    2014-01-01

    Resumen Las cepas de E. coli patógenas intestinales son causas importantes de la enfermedad diarreica aguda (EDA) en niños menores de 5 años en América Latina, África y Asia y están asociadas a alta mortalidad en niños en las comunidades más pobres de África y el Sudeste Asiático. Estudios sobre el papel de las E. coli patógenas intestinales en la EDA infantil en Colombia y otros países de América Latina son limitados debido a la carencia de ensayos para detección de estos patógenos en los laboratorios clínicos de centros de salud. Estudios recientes han reportado la detección de E. coli patógenas intestinales en Colombia, siendo la E. coli enterotoxigénica la cepa más frecuentemente asociada a diarrea en niños menores de 5 años. Otros patógenos detectados en estos pacientes incluyen las E. coli enteroagregativa, enteropatógena, productora de toxina Shiga, y de adherencia difusa. Con base en estudios que reportan la presencia de E. coli productora de toxina Shiga y E. coli enteroagregativa en carnes y vegetales en supermercados, se cree que productos alimentarios contaminados contribuyen a la transmisión de estos patógenos y a la infección del huésped susceptible. Más estudios son necesarios para evaluar los mecanismos de transmisión, el impacto en la epidemiologia de la EDA, y las pautas de manejo y prevención de estos patógenos que afectan la población pediátrica en Colombia.

  2. Bilateral cellulitis.

    PubMed

    Batra, Vivek; Baras, Alexander

    2015-01-01

    We present a case of bilateral lesions in a 50-year-old man, which were on first impression mistaken for and initially treated as bilateral cellulitis. We propose that bilateral cellulitis, as opposed to unilateral, is rare and that other aetiologies should be considered in evaluating a patient with bilateral lesions. The differential diagnosis includes stasis-dermatitis, lipodermatosclerosis, lymphoedema and vascular lesions such as Kaposi sarcoma, as was identified in this case. Early consultation with dermatology and biopsy in unclear cases mitigates the unnecessary use of prolonged antibiotics, antibiotic resistance and Clostridium difficile infections. HIV testing is an essential screening test in all adults who present with non-specific viral symptoms and rash. PMID:26392449

    The bilateral operculum syndrome, is a unique developmental syndrome. It is characterized by spastic paralysis of the muscles of the face, pharynx, and of mastication, as well as by epilepsy and mental retardation. Imaging studies show bilateral, structural abnormalities in the frontal, perisylvian region consistent with polymicrogyria. These children are usually diagnosed as suffering from cerebral palsy, but in the bilateral operculum syndrome, intelligence is relatively preserved despite the severe motor involvement. Misdiagnosis may lead to improper estimation of rehabilitation potential preventing appropriate therapy, especially in the field of alternative communication. We present a 3-year-old boy, apparently the first case of this syndrome to be described in Israel. PMID:8940497

  5. Echinoderms Have Bilateral Tendencies

    2012-01-01

    Echinoderms take many forms of symmetry. Pentameral symmetry is the major form and the other forms are derived from it. However, the ancestors of echinoderms, which originated from Cambrian period, were believed to be bilaterians. Echinoderm larvae are bilateral during their early development. During embryonic development of starfish and sea urchins, the position and the developmental sequence of each arm are fixed, implying an auxological anterior/posterior axis. Starfish also possess the Hox gene cluster, which controls symmetrical development. Overall, echinoderms are thought to have a bilateral developmental mechanism and process. In this article, we focused on adult starfish behaviors to corroborate its bilateral tendency. We weighed their central disk and each arm to measure the position of the center of gravity. We then studied their turning-over behavior, crawling behavior and fleeing behavior statistically to obtain the center of frequency of each behavior. By joining the center of gravity and each center of frequency, we obtained three behavioral symmetric planes. These behavioral bilateral tendencies might be related to the A/P axis during the embryonic development of the starfish. It is very likely that the adult starfish is, to some extent, bilaterian because it displays some bilateral propensity and has a definite behavioral symmetric plane. The remainder of bilateral symmetry may have benefited echinoderms during their evolution from the Cambrian period to the present. PMID:22247765

    2012-01-01

    A clinical feature of bilateral popliteal arterial dissection without involving the descending aorta, bilateral iliac, as well as femoral arteries has never been reported in the past literature. We report a 56-year-old man with hypertension and coronary artery disease who presented to our emergency department with complaints of bilateral knee pain after long-distance walking. Physical examination was notable for elevated blood pressure, but there was no palpable pulsation over dorsalis pedis arteries on his feet. Laboratory evaluation revealed a d-dimer level of 35.2 mg/L (FEU) on the day of the test and 1.2 mg/L one and a half months ago (normal level, <0.55). These findings were suggestive of a recent-onset peripheral arterial occlusive disorder. Computed tomography of the aorta showed bilateral popliteal arterial dissection with arterial intimal flap. Abdominal aorta, bilateral iliac, and femoral arteries remained intact with only arteriosclerotic change. Minimally invasive endovascular stent grafting was then performed. The patient had an uneventful recovery. PMID:21106320

    1997-11-01

    We reported a 67-year-old woman with bilateral caudate head infarcts. She developed sudden mutism followed by abulia. She was admitted to our hospital 2 months after ictus for further examination. She showed prominent abulia and was inactive, slow and apathetic. Spontaneous activity and speech, immediate response to queries, spontaneous word recall and attention and persistence to complex programs were disturbed. Apparent motor disturbance, gait disturbance, motor aphasia, apraxia and remote memory disturbance were not identified. She seemed to be depressed but not sad. Brain CT and MRI revealed bilateral caudate head hemorrhagic infarcts including bilateral anterior internal capsules, in which the left lesion was more extensive than right one and involved the part of the left putamen. These infarct locations were thought to be supplied by the area around the medial striate artery including Heubner's arteries and the A1 perforator. Digital subtraction angiography showed asymptomatic right internal carotid artery occlusion. She bad had hypertension, diabetes mellitus and atrial fibrillation and also had a left atrium with a large diameter. The infarcts were thought to be caused by cardioembolic occlusion to the distal portion of the left internal carotid artery. Although some variations of vasculature at the anterior communicating artery might contribute to bilateral medial striate artery infarcts, we could not demonstrate such abnormalities by angiography. Bilateral caudate head infarcts involving the anterior internal capsule may cause prominent abulia. The patient did not improve by drug and rehabilitation therapy and died suddenly a year after discharge. PMID:9503974

    Osteomas are the most common benign osteoclastic tumours of the paranasal sinuses. However, nasal cavity and turbinate osteomas are extremely rare. Only nine middle turbinate, three inferior turbinate and one inferior turbinate osteoma cases have been reported to date. The present case report describes the management and follow-up of symptomatic bilateral inferior turbinate osteoma.A 60-year-old female presented with symptoms of bilateral nasal obstruction and right-sided epiphora. Radiological investigation found hypertrophic bony changes involving both inferior turbinates. The patient was managed successfully by endoscopic inferior turbinectomies in order to achieve a patent airway, with no further recurrence of tumour after 3 months postoperatively.To the best of our knowledge, this is the first reported case of bilateral inferior turbinate osteoma. We describe a safe and minimally invasive method of tumour resection, which has a better cosmetic outcome compared with other approaches. PMID:27534890

  9. Efficacy of bilateral pallidotomy.

    Unilateral pallidotomy is a safe and effective treatment for medically refractory bradykinetic Parkinson's disease, especially in those patients with levodopa-induced dyskinesia and severe on-off fluctuations. The efficacy of bilateral pallidotomy is less certain. The authors completed 11 of 12 attempted bilateral pallidotomies among 150 patients undergoing pallidotomy at New York University. In all but one patient, the pallidotomies were separated by at least 9 months. Patients were selected for bilateral pallidotomy if they exhibited bilateral rigidity, bradykinesia, or levodopa-induced dyskinesia prior to treatment or if they exhibited disease progression contralateral to their previously treated side. The Unified Parkinson's Disease Rating Scale (UPDRS) and timed upper-extremity tasks of the Core Assessment Protocol for Intracerebral Transplantation (CAPIT) were administered to all 12 patients in the "off" state (12 hours without receiving medications) preoperatively and again at 6 and 12 months after each procedure. The median UPDRS and contralateral CAPIT scores improved 60% following the initial procedure (p = 0.008, Wilcoxon rank sums test). The second pallidotomy generated only an additional 10% improvement in the UPDRS and CAPIT scores ipsilateral to the original procedure (p = 0.05). Worsened speech was observed in two cases. In the 12th case, total speech arrest was noted during test stimulation. Speech returned within minutes after stimulation was halted. Lesioning was not performed. These results indicate that bilateral pallidotomy has a narrow therapeutic window. Motor improvement ipsilateral to the first lesion leaves little room for further improvement from the second lesion and the risk of speech deficit is greatly enhanced. Chronic pallidal stimulation contralateral to a previously successful pallidotomy may prove to be a safer alternative for the subset of patients who require bilateral procedures. PMID:15096015

    Primary ovarian lymphoma is a rare entity. We submit a case of a 34-year-old black patient presenting with a bilateral adnexal tumor. She underwent hysterectomy with double salpingo-oophorectomy followed by polychemotherapy treatment. Histology confirmed Epstein-Barr virus-positive bilateral Burkitt's lymphoma. The patient died from septic shock after a month of treatment. Endemic Burkitt's lymphoma has a predilection for the female genital tract, manifesting itself clinically as a pelvic mass and less frequently as a menstrual disorder. It is a rare entity in our environment but should be kept in mind when treating patients of African origin. PMID:19480266

    2013-01-01

    The bilateral sagittal split osteotomy is an indispensable tool in the correction of dentofacial abnormalities. The technique has been in practice since the late 1800s, but did not reach widespread acceptance and use until several modifications were described in the 1960s and 1970s. Those modifications came from a desire to make the procedure safer, more reliable, and more predictable with less relapse. Those goals continue to stimulate innovation in the field today and have helped the procedure evolve to be a very dependable, consistent method of correction of many types of malocclusion. The operative surgeon should be well versed in the history, anatomy, technical aspects, and complications of the bilateral sagittal split osteotomy to fully understand the procedure and to counsel the patient.

    Purpose: To describe a case of bilateral presumed tuberculous choroiditis which resolved promptly with a short course of antituberculous therapy. Case Report: A 44-year-old lady presented with bilateral visual loss of 8 months’duration. Considering the presence of pan-uveitis, severe macular edema, multifocal leakage on fluorescein angiography, positive tuberculin skin test, and after excluding other diseases, she underwent anti-tuberculous therapy (ATT) for disseminated choroiditis due to presumed ocular tuberculosis. She improved promptly and completely. There were no signs of relapse 18 months after completion of the treatment course. In a young patient with disseminated choroiditis and relatively short duration of symptoms, a course of ATT for 6 months may effectively treat the disease preventing relapse for a considerable period of time. Conclusion: In Presumed Tuberculous chroiditis early diagnosis is crucial for prompt and complete improvement. PMID:27413507

    Bilateral renal calculi were present in 114 (10.7%) of 1,070 cases of proved urinary calculus admitted to the Urological Department of the General Hospital, Kuala Lumpur, during the period November 1968—May 1973. The management of bilateral renal calculi is discussed with reference to the first 100 cases in this series. The introduction of renography has greatly facilitated the decision as to which kidney should be operated on first. The management of patients with and without uraemia is discussed and the use of the modified V and V—Y incisions for the removal of staghorn calculi is described. Complications and results are briefly reviewed. ImagesFig. 1Fig. 4Fig. 6Fig. 7 PMID:4845653

    ABSTRACT Supernumerary tooth is a developmental anomaly and has been argued to arise from multiple etiologies. These teeth may remain embedded in the alveolar bone or can erupt into the oral cavity. They can cause a variety of complications in the develo­ping dentition. Supernumerary teeth can present in various forms and in any region of the mandible or maxilla, but have a predisposition for the anterior maxilla. Here is the presentation of a case of unusual location of supernumerary teeth located in between mandibular first and second molar region bilaterally. How to cite this article: Dhull KS, Dhull RS, Panda S, Acharya S, Yadav S, Mohanty G. Bilateral Mandibular Paramolars. Int J Clin Pediatr Dent 2014;7(1):40-42. PMID:25206236

    Cutaneous leiomyomas are benign smooth muscle neoplasms of the skin. They arise from vascular, arrector pili, genital, and areolar smooth muscles. The most common localizations of cutaneous leiomyomas are the extensor surfaces of the extremities and the trunk. To our knowledge, only few cases of one-sided nipple leiomyomas have been reported, but two-sided nipple leiomyomas have not been presented. For the first time, here, we report a bilateral nipple leiomyoma. PMID:23762734

  18. Compressive Bilateral Filtering.

    2015-11-01

    This paper presents an efficient constant-time bilateral filter that produces a near-optimal performance tradeoff between approximate accuracy and computational complexity without any complicated parameter adjustment, called a compressive bilateral filter (CBLF). The constant-time means that the computational complexity is independent of its filter window size. Although many existing constant-time bilateral filters have been proposed step-by-step to pursue a more efficient performance tradeoff, they have less focused on the optimal tradeoff for their own frameworks. It is important to discuss this question, because it can reveal whether or not a constant-time algorithm still has plenty room for improvements of performance tradeoff. This paper tackles the question from a viewpoint of compressibility and highlights the fact that state-of-the-art algorithms have not yet touched the optimal tradeoff. The CBLF achieves a near-optimal performance tradeoff by two key ideas: 1) an approximate Gaussian range kernel through Fourier analysis and 2) a period length optimization. Experiments demonstrate that the CBLF significantly outperforms state-of-the-art algorithms in terms of approximate accuracy, computational complexity, and usability. PMID:26068315

    Background Bilateral breast cancer (BBC) is not an uncommon entity in contemporary breast clinics. Improved life expectancy after breast cancer treatment and routine use of contra-lateral breast mammography has led to increased incidence of BBC. Our study objective was to define the epidemiological and tumour characteristics of BBC in India. Materials and Methods A total of 1251 breast cancer patients were treated during the period January 2007 to March 2015 and 30 patients were found to have BBC who constituted the study population (60 tumour samples). Synchronous bilateral breast cancers (SBC) was defined as two tumours diagnosed within an interval of 6 months and a second cancer diagnosed after 6 months was labelled as metachronous breast cancer (MBC). Analyses of patient and tumour characteristics were done in this prospective data base of BBC patients. Results Median patient age was 66 years (range 39-85). Majority of the patients had SBC (n=28) and in 12 patients the second tumour was clinically occult and detected only by mammography of the contra-lateral breast. The second tumour was found at lower tumour size compared to the first in 73% of cases and was negative for axillary metastasis in 80% of cases (24/30). Infiltrating ductal carcinoma was the commonest histological type (n=51) and majority of the tumours were ER/PR positive (50/60). Her2 was overexpressed in 13 tumours (21%). Over 70% (22/30) of patients had similar histology in both breasts and amongst them grade concordance was present in about 69% (15/22) of patients. Concordance rates of ER, PR and Her2 statuses were 83%, 80% and 90% respectively. Bilateral mastectomy was the commonest surgery performed in 80% of the patients followed by bilateral breast conservation in 13%. At the end of study period, 26 patients were alive and disease free. Median survival was 29 months (range 3-86 months). Conclusion In most patients with BBC, the second tumour is identified at an early stage than index

    Posterior sternoclavicular dislocations are a rare injury, representing <5% of all sternoclavicular dislocations and 1 in 1600 shoulder girdle injuries. Proper imaging with computed tomography and prompt diagnosis are essential steps in preventing potentially lethal complications observed in approximately 3% of all posterior sternoclavicular dislocations. Surgical treatment is necessary if closed reduction fails. With the medial clavicular epiphysis being the last to close (between ages 22 and 25), children and adolescents typically present with epiphyseal fractures rather than joint dislocations. If closed reduction fails, open reduction and internal fixation (ORIF) should be considered in fractures, whereas complex reconstructions with tendon graft procedures have been recommended for joint dislocations. This article presents a case of a traumatic bilateral posterior sternoclavicular dislocation due to an epiphyseal fracture in a 15-year-old boy. To our knowledge, this is the first reported case of a bilateral posterior sternoclavicular dislocation. Attempted closed reduction failed with redislocation after 2 days. The patient subsequently required ORIF. This article describes our technique with anterior retraction of the medial clavicle, closure of the posterior periosteum, and ORIF using nonabsorbable sutures. Postoperative shoulder mobilization was started on day 1. At final follow-up, the patient was completely asymptomatic. PMID:20608625

    We describe 12 patients with simultaneous bilateral spontaneous pneumothorax (SBSP). They represent 4 percent of patients with spontaneous pneumothorax seen at our hospital from 1971 to 1990. Five of the 12 had no underlying lung disease. In the seven remaining patients, SBSP was secondary to histiocytosis X, lymphangioleiomyomatosis, osteogenic sarcoma with pleural and pulmonary metastases, Hodgkin's disease, mesothelioma, cystic fibrosis, or miliary tuberculosis. Nineteen of the 56 patients with SBSP (34 percent) described in the literature (this series included) had pulmonary disease related to disorders of cells of mesenchymal origin. Emphysema and bullous lung disease were not associated with SBSP. Long-term prognosis was a function of pulmonary status. Four of the patients described herein died during the period reviewed. All suffered from severe underlying disease. In no case was SBSP the main cause of death. With timely treatment, the short-term prognosis is benign even for patients with underlying lung disease. Surgical pleurectomy should be attempted early, especially in SBSP secondary to underlying lung disease. PMID:8162740

    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.

    Objective Report on the 7-year experience with bilateral ophthalmic artery chemosurgery (OAC-Tandem therapy) for bilateral retinoblastoma. Design Retrospective, single institution study. Subjects 120 eyes of 60 children with bilateral retinoblastoma treated since March 2008. Methods Retrospective review of all children treated at Memorial Sloan Kettering with bilateral ophthalmic artery chemosurgery (Melphalan, Carboplatin, Topotecan, Methotrexate) delivered in the same initial session to both naïve and previously treated eyes. Main Outcome Measures Ocular survival, metastatic disease, patient survival from metastases, second cancers, systemic adverse effects, need for transfusion of blood products, electroretinogram before and after treatment. Results 116 eyes were salvaged (4 eyes were enucleated: 3 because of progressive disease, 1 family choice). Kaplan Meier ocular survival was 99.2% at one year, 96.9% at 2 and 3 years and 94.9% for years 4 through 7. There were no cases of metastatic disease or metastatic deaths with a mean follow-up of 3.01 years. Two children developed second cancers (both pineoblastoma) and one of them died. Transfusion of blood products was required in 3 cases (4 transfusions), 1.9%. Two children developed fever/neutropenia requiring hospitalization (0.95%). ERGs were improved in 21.6% and unchanged after treatment in 52.5% of cases (increase or decrease of less than 25μV). Conclusions Bilateral ophthalmic artery chemosurgery is a safe and effective technique for managing bilateral retinoblastoma-even when eyes are advanced bilaterally, and if both eyes have progressed after systemic chemotherapy. Ocular survival was excellent (94.9% at 8 years), there were no cases of of metastatic disease and no deaths from metastatic disease, but children remain at risk for second cancers. In 21.6% of cases ERG function improved. Despite using chemotherapy in both eyes in the same session, systemic toxicity was low. PMID:27258771

    A 19-year-old woman with insulin-dependent diabetes mellitus developed pain and tenderness in the medial aspect of the left thigh and calf, followed 1 week later by similar symptoms in the right leg. Technetium 99m pyrophosphate (PYP) radionuclide scans showed increased flow and uptake in the medial thigh muscles. Magnetic resonance imaging (MRI) of the thigh showed increased signal on proton density and T2-weighted images in the medial and lateral thigh compartments. High-resolution B-mode ultrasound showed hyperechoic changes in the anteromedial thigh muscles, with loss of normal myofascial interfaces, and a mixed appearance, bilaterally. Two months later, after the symptoms had begun to resolve, the images had improved. This case documents bilateral diabetic thigh infarction identified by abnormal technetium 99m PYP flow studies, MRI signal, and B-mode ultrasound imaging. PMID:8136579

    Bilateral loss of vestibular inputs affects far fewer patients than unilateral inner ear damage, and thus has been understudied. In both animal subjects and human patients, bilateral vestibular hypofunction (BVH) produces a variety of clinical problems, including impaired balance control, inability to maintain stable blood pressure during postural changes, difficulty in visual targeting of images, and disturbances in spatial memory and navigational performance. Experiments in animals have shown that non-labyrinthine inputs to the vestibular nuclei are rapidly amplified following the onset of BVH, which may explain the recovery of postural stability and orthostatic tolerance that occurs within 10 days. However, the loss of the vestibulo-ocular reflex and degraded spatial cognition appear to be permanent in animals with BVH. Current concepts of the compensatory mechanisms in humans with BVH are largely inferential, as there is a lack of data from patients early in the disease process. Translation of animal studies of compensation for BVH into therapeutic strategies and subsequent application in the clinic is the most likely route to improve treatment. In addition to physical therapy, two types of prosthetic devices have been proposed to treat individuals with bilateral loss of vestibular inputs: those that provide tactile stimulation to indicate body position in space, and those that deliver electrical stimuli to branches of the vestibular nerve in accordance with head movements. The relative efficacy of these two treatment paradigms, and whether they can be combined to facilitate recovery, is yet to be ascertained. PMID:22207864

  11. Multiresolution Bilateral Filtering for Image Denoising

    2008-01-01

    The bilateral filter is a nonlinear filter that does spatial averaging without smoothing edges; it has shown to be an effective image denoising technique. An important issue with the application of the bilateral filter is the selection of the filter parameters, which affect the results significantly. There are two main contributions of this paper. The first contribution is an empirical study of the optimal bilateral filter parameter selection in image denoising applications. The second contribution is an extension of the bilateral filter: multiresolution bilateral filter, where bilateral filtering is applied to the approximation (low-frequency) subbands of a signal decomposed using a wavelet filter bank. The multiresolution bilateral filter is combined with wavelet thresholding to form a new image denoising framework, which turns out to be very effective in eliminating noise in real noisy images. Experimental results with both simulated and real data are provided. PMID:19004705

    Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from severe or treatment-resistant major depressive disorder (MDD). Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups. Our results reveal that ECT induces significant, bilateral increases in cortical thickness, including the temporal pole, inferior and middle temporal cortex and the insula. The pattern of increased cortical thickness was predominant in regions that are associated with seizure onset in ECT. Post hoc analyses showed that the increase in thickness of the insular cortex was larger in responders than in non-responders, which may point to a specific relationship of this region with treatment effects of ECT.

    Depth maps are used in many applications, e.g. 3D television, stereo matching, segmentation, etc. Often, depth maps are available at a lower resolution compared to the corresponding image data. For these applications, depth maps must be upsampled to the image resolution. Recently, joint bilateral filters are proposed to upsample depth maps in a single step. In this solution, a high-resolution output depth is computed as a weighted average of surrounding low-resolution depth values, where the weight calculation depends on spatial distance function and intensity range function on the related image data. Compared to that, we present two novel ideas. Firstly, we apply anti-alias prefiltering on the high-resolution image to derive an image at the same low resolution as the input depth map. The upsample filter uses samples from both the high-resolution and the low-resolution images in the range term of the bilateral filter. Secondly, we propose to perform the upsampling in multiple stages, refining the resolution by a factor of 2×2 at each stage. We show experimental results on the consequences of the aliasing issue, and we apply our method to two use cases: a high quality ground-truth depth map and a real-time generated depth map of lower quality. For the first use case a relatively small filter footprint is applied; the second use case benefits from a substantially larger footprint. These experiments show that the dual image resolution range function alleviates the aliasing artifacts and therefore improves the temporal stability of the output depth map. On both use cases, we achieved comparable or better image quality with respect to upsampling with the joint bilateral filter in a single step. On the former use case, we feature a reduction of a factor of 5 in computational cost, whereas on the latter use case, the cost saving is a factor of 50.

    Telemanipulator system includes master robot manipulated by human operator, and slave robot performing tasks at remote location. Two robots electronically coupled so slave robot moves in response to commands from master robot. Teleoperation greatly enhanced if forces acting on slave robot fed back to operator, giving operator feeling he or she manipulates remote environment directly. Main advantage of bilateral impedance control: enables arbitrary specification of desired performance characteristics for telemanipulator system. Relationship between force and position modulated at both ends of system to suit requirements of task.

    Macrodontia is a rare dental anomaly that refers to teeth that appear larger than normal. Generalised macrodontia can be associated with certain medical conditions and syndromes. This case report presents clinical and radiographic findings of isolated bilateral macrodontia in a 14-year-old child. The patient was referred to the clinic with local crowding of maxillary and mandibular teeth. Radiographic findings revealed the presence of impacted macrodont mandibular second premolar on one side and erupted macrodontic premolar on the other side and their distinct morphological appearance, characterized by large, multitubercular, and molariform crowns and tapering, single roots.

    Sequentially evolved bilateral epidural haematomas, where the second haematoma evolves after surgical removal of the first haematoma, are rarely reported. We report two cases of this entity. One patient was involved in a road traffic accident and the other was suffering from a head injury after an assault. CT scans showed that both patients had an unilateral epidural haematoma with a thin presumably epidural haemorrhage on the opposite side. Both patients were operated for their epidural haematomas, but did not improve after surgical treatment, and postoperative CT scans revealed evolving of an epidural haematoma on the opposite side. After evacuation of the second epidural haematoma both patients recovered quickly. Sequentially evolved bilateral epidural haematomas are rare, but must be considered in the postoperative intensive care treatment in patients with epidural haematomas. Both cases emphasize the need for intensive care monitoring after an operation for an epidural haematoma and the need for CT scans if the patient does not improve quickly after removal of the haematoma. This is especially important if a small contralateral haematoma is seen on the initial CT scan. PMID:12445923

    A case report of a 44 year-old white man admitted to the surgical unit for a bilateral simultaneous pneumothorax is presented. The pneumothorax occurred on day one after a surgical operation for discal hernia; in the past the patient already presented a right spontaneous pneumothorax at 32 years of age and a left pneumothorax at 37 years of age, both treated with a pleural drainage. A thoracic drain was bilaterally positioned with a good result only in the right side. The persistence of the left pneumothorax induced the authors to perform a postero-lateral thoracotomy bullae excision and pleurectomy with a good postoperative course. After a few months a new right pneumothorax occurred and the patient was treated with a right postero-lateral thoracotomy, bullae resection and pleurectomy. On the basis of the case reported, the authors consider the different opportunities in the treatment of spontaneous pneumothorax in relation to the present knowledges and technologies. Surgical procedure is to be preferred in case of persistence of pneumothorax despite a pleural drain and in case of pneumothorax in high risk subjects. Even if thoracoscopy seems to give better results regarding postoperative pain, it is not always possible with such a method to perform a careful pleurectomy neither to obtain it in all cases (above all in secondary pneumothorax). Every case must then be carefully studied to choose the best treatment at present available. PMID:11353349

  18. Bilateral internal thoracic artery grafting

    PubMed Central

    2013-01-01

    The effectiveness of the left internal mammary artery graft to the anterior descending coronary artery as a surgical strategy has been shown to improve the survival rate and decrease the risk of adverse cardiac events in patients undergoing coronary bypass surgery. These clinical benefits appear to be related to the superior short and long-term patency rates of the internal thoracic artery graft. Although the advantages of using of both internal thoracic arteries (ITA) for bypass grafting have taken longer to prove, recent results from multiple data sets now support these findings. The major advantage of bilateral ITA grafting appears to be improved survival rate, while the disadvantages of complex ITA grafting include the increased complexity of operation, and an increased risk of wound complications. While these short-term disadvantages have been mitigated in contemporary surgical practice, they have not eliminated. Bilateral ITA grafting should be considered the procedure of choice for patients undergoing coronary bypass surgery that have a predicted survival rate of longer than ten years. PMID:23977627

    Although bilateral orbital fracture can cause serious eyeball and facial skeletal problems, few reports have been issued on the topic. We analyzed the clinical features of bilateral orbital fracture by reviewing the medical records of 147 patients and compared bilateral and unilateral fractures by reviewing the literature.Bilateral orbital fracture was most common in men aged between 50 and 59 years. A traffic accident was the leading cause of trauma, and average time between trauma and surgery was 12.2 days. Bilateral medial fracture accompanied by nasal fracture accounted for the overwhelming majority, and impure blowout fracture in at least 1 eye occurred in 69.4% of the 147 patients. Associated ocular injuries seemed to be similar for bilateral and unilateral fracture. Thirty-five patients (23.8%) had other multiple traumas affecting other than the eyes, and this significantly increased the need for surgery (P < 0.05). Of the 48 patients who underwent surgery, including 4 cases of bilateral surgery, 21 patients who had ocular motility restriction with central diplopia within 30 degrees almost completely recovered. No significant relation between the timing of surgery and improvement was found. Although unilateral surgery was performed in most cases, facial asymmetry related to enophthalmos was unclear at 6 months postoperatively.In summary, bilateral orbital fracture was found to be clinically distinguishable from unilateral fracture in several aspects. We hope these findings provide a reference guide to the approach and management of bilateral orbital fracture. PMID:24514894

    We propose a constant-time algorithm for a bilateral filter. Bilateral filter can be converted into the operation of three-dimensional (3D) convolution. By using recursive moving sum, we can reduce the number of calculations needed to construct a pseudo-Gaussian filter. Applying one-dimensional Gaussian filter to the 3D convolution, we achieved a constant-time bilateral filter. We used a 3-GHz CPU without SIMD instructions, or multi-thread operations. We confirmed our proposed bilateral filter to be processed in constant time. In practical conditions, high PSNR values over 40 dB are obtained.

We present a case of a 69-year-old bilateral below-knee amputee male admitted to the emergency department with bilateral hip pain and radiological evidence of bilateral displaced neck of femur fractures. The patient subsequently underwent synchronous bilateral total hip replacements under general anaesthetic and an epidural and then went on to make a full recovery. He was discharged 27 days after arrival in hospital. Outpatient follow-up at 3 months has shown that the patient has returned to a similar level of preinjury function and is still able to carry out his daily activities with walking aids and bilateral leg prostheses.

    A 4-year-old, otherwise healthy white girl was referred for a 15-month history of alopecia areata. Anthralin 0.1% cream was prescribed for the left side of the scalp, while corticosteroids for the right side. After 4 months, only the right side of the scalp showed hair regrowth. Half-side strategy, that is, treating one side and managing the other--divided by the mid sagittal suture--as an internal control for no treatment, placebo or other treatment, has been commonly used in clinical studies for decades. In everyday practice, bilateral treatment is useful to evaluate the responsiveness to two topically delivered interventions and diminishes the time necessary to identify an effective one.

    Bilateral adrenal hemorrhage with subsequent adrenal insufficiency is a recognized complication of anticoagulant therapy. Because the clinical manifestations are often nonspecific, the antemortem diagnosis of adrenal hemorrhage has been a difficult clinical problem. Computed tomography (CT) provides detailed images of the adrenal glands that are not possible with conventional imaging methods. The CT findings of bilateral adrenal hemorrhage in an anticoagulated patient are reported.

    We herein report a rare case of sarcoidosis presenting as bilateral vocal cord paralysis due to bilateral vagal nerve involvement. A 72-year-old woman with uveitis of the left eye complained of hoarseness and aspiration due to bilateral vocal cord paralysis. An endobronchial needle aspiration biopsy specimen of the mediastinal lymph nodes showed non-caseating epithelioid cell granuloma. Total protein and cell concentrations in the cerebrospinal fluid were increased. We diagnosed her to have sarcoidosis with bilateral vagal nerve involvement. Corticosteroid therapy improved her symptoms of hoarseness and aspiration. Sarcoidosis should therefore be taken into consideration as a potential cause of bilateral vocal cord paralysis.

    Ectopic pregnancy is identified with the widely-applied assisted reproductive technology (ART). Bilateral ectopic pregnancy is a rare form of ectopic pregnancy which is difficult to be diagnosed at the pre-operation stage. In this paper, we presented an unusual case of heterochronic bilateral ectopic pregnancy after stimulated intrauterine insemination (IUI), where there has been a delay of 22 d between the diagnoses of the two ectopic pregnancies. Literature was reviewed on the occurrence of bilateral ectopic pregnancy during the past four years in the MEDLINE database. We found 16 cases of bilateral ectopic pregnancy reported since 2008, and analyzed the characteristics of those cases of bilateral ectopic pregnancy. We emphasize that ovulation induction and other ARTs may increase the risk of bilateral ectopic pregnancy. Because of the difficulty in identification of bilateral ectopic pregnancy by ultrasonography, the clinician should be aware that the treatment of one ectopic pregnancy does not preclude the occurrence of a second ectopic pregnancy in the same patient and should pay attention to the intra-operation inspection of both side fallopian tubes in any ectopic pregnancy case.

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing's syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88-100% and 67-100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50-70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. PMID:27352844

    Among complications in orthognathic surgery, the insurgence of pneumothorax is very rare. Pneumothorax is the presence of air or gas in the pleural cavity and it is rare complications in the postoperative oral and maxillofacial surgery patient. The clinical results are dependent on the degree of collapse of the lung on the affected side. Pneumothorax can impair oxygenation and/or ventilation. If the pneumothorax is significant, it can cause a shift of the mediastinum and compromise haemodynamic stability. While 10% of pneumothoraces are asymptomatic, patients often complain of acute chest pain and difficulty breathing. There is a reduction in vital capacity, tachycardia, tachypnoea and a decrease in partial pressure of oxygen with an inability to maintain oxygen saturations. We observed this unusual surgical consequence in a 28-year-old female with negative clinical history and instrumental evaluation after Le Fort I osteotomy and bilateral sagittal split osteotomy (BSSO). No further consequences, no neurological sequelae, no infections and no other osteotomies sequelae were seen. Sudden post-surgical dispnea associated to sub-cutaneous emphysema of the neck and of the thorax must be adequately observed with the aim of monitoring further severe sequelae. The anaesthetic management of the emergency difficult airway in any post-surgical orthognatic treatment can be extremely difficult requiring a multi-disciplinary approach. PMID:23814593

    The first retroperitoneal lumbar sympathectomy was performed in 1924 by Julio Diez. The classic procedure for sympathectomy is open surgery. We report a unilateral laparoscopic retroperitoneal approach to perform bilateral lumbar sympathectomy. This approach was performed for a 43-year-old man with distal arterial occlusive disease and no indication for direct revascularization. His predominant symptoms were intermittent claudication at 100 metres and cold legs. The patient was placed in a left lateral decubitus position. The optical system was placed first in an intra-abdominal position to check that the trocars were well positioned in the retroperitoneal space. The dissection of retroperitoneum was performed by CO2 insufflation. The inferior vena cava was reclined and the right sympathetic chain was individualized. Two ganglia (L3-L4) were removed by bipolar electro-coagulation. The aorta was isolated on a vessel loop and careful anterior traction allowed a retro-aortic pre-vertebral approach between the lumbar vessels. The left sympathetic chain was dissected. Two ganglia (L3-L4) were removed by bipolar electro-coagulation. PMID:17685269

    There are three main highland areas on Venus: Beta Regio, Ishtar Terra and Aphrodite Terra. The latter is least known and the least mapped, yet existing analyses of Aphrodite Terra based on available Pioneer-Venus orbiter data suggest that it may be the site of extensive rifting. Some of the highest resolution (30 km) PV data (SAR) included most of the western half of Aphrodite Terra. Recent analysis of the SAR data together with Arecibo range-doppler topographic profiling (10 X 100 km horizontal and 10 m vertical resolution) across parts of Aphrodite, further characterized the nature of possible tectonic processes in the equatorial highlands. The existence of distinct topographic and radar morphologic linear discontinuities across the nearly east-west strike of Aphrodite Terra is indicated. Another prominent set of linear features is distinctly parallel to and orthogonal to the ground tracks of the PV spacecraft and are not included because of the possibility that they are artifacts. Study of the northwest trending cross-strike discontinuities (CSD's) and the nature of topographic and morphologic features along their strike suggest the presence of bilateral topographic and morphologic symmetry about the long axis of Aphrodite Terra.

    Dorsal wrist pain and swelling is commonly attributed to a dorsal wrist ganglion. However, based on the authors' experience, a cautious surgeon should keep the uncommonly symptomatic diagnosis of an extensor digitorum brevis manus in their differential despite classic ganglion presentation and suggestive advanced imaging. This article describes a case of a young patient who presented with bilateral symptomatic extensor digitorum brevis manus anomalies that required surgical intervention. An extensor digitorum brevis manus is present in 3% of the population in a classic anatomy study from Japan and is most commonly symptomatic with heavy activity and extremes of wrist extension. Anatomically, the extensor digitorum brevis manus is located in the fourth wrist compartment and most commonly inserts on the index finger extensor mechanism. Examination often reveals a spindle-shaped mass that is palpable distal to the extensor mechanism and moves with extensor tendon motion. Magnetic resonance imaging shows a typical dorsal mass distal to the common extensors with a similar signal as muscle with all image sequencing. Treatment includes activity alterations to relieve symptoms or surgical excision of the muscle belly for refractory cases with care taken to preserve the index extensor mechanism. PMID:22955414

    Neurofibromatosis is a neuroectodermal systemic disease. A rare variant of this condition is bilateral segmental neurofibromatosis. A 29-year-old man presented with bilateral papillomatous plaques in the lumbar dermatomes. Clinically, the lesions were very similar to an epidermal nevus but histologic examination revealed superficial neurofibromas. Family history, ophthalmologic and neurologic investigations were unremarkable. The unusual morphologic presentation of bilateral segmental neurofibromas in this case points to the wide clinical spectrum of the disease and the significance of histologic examination in systematic nevoid lesions.

    A 77-year-old man presented with an acute worsening of chronic back pain. CT showed dense bilateral adrenal glands suggestive of adrenal haemorrhage which was confirmed by MRI. Despite appropriate glucocorticoid replacement for adrenal insufficiency, 7 days after admission this patient suffered an adrenal crisis. Owing to the timely diagnosis, appropriate treatment was given and the patient survived. Large bilateral adrenal haemorrhage however, can lead to cardiovascular collapse and death if not appropriately diagnosed and managed promptly. Despite its rarity, bilateral adrenal haemorrhage should always be considered as a differential for back pain in the setting of an acute illness due to its potentially fatal consequences.

    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.

    The purpose of this study was to evaluate the bilateral coordination in children and adolescents with visual impairments aged 7 to 18 years in comparison to their sighted peers. An additional objective was to identify the influence of sex and age on bilateral coordination. Seventy-five individuals with congenital severe visual impairment (40 girls and 35 boys) comprised the visually impaired group. The Sighted group comprised 139 youth without visual impairment. Subtest 4 of the Bruininks-Oseretsky Test of Motor Proficiency was administered to test bilateral coordination. To analyze the effect of the independent variables in the results obtained in the Subtest 4, four linear regression models were applied according to group and sex. The results indicated that severe visual impairment and lack of visual sensation had a negative effect on the development of participants' bilateral coordination, which however did not depend on sex or age.

    Bilateral anterior glenohumeral dislocation is a rare occurrence. We present a case of bilateral anterior glenohumeral dislocation caused by a fall. The interest in publishing this case is that this is a clinical rarity with few cases reported in the literature. An 89-year-old female patient was brought to the emergency department after a fall, complaining of intense pain in both shoulders and inability to move them. Objective examination showed clinical signs giving the suspicion of bilateral anterior glenohumeral dislocation, which was confirmed by x-ray imaging. Both dislocations were successfully reduced in the emergency department using the modified Milch technique. When a synchronous and symmetrical force has acted on both shoulders and these are painful with significant functional limitation, the suspicion of bilateral glenohumeral dislocation is a differential diagnosis to be considered, even though it is rare.

    A 64 year old woman with a predominantly midline pontine tegmental haemorrhage presented with bilateral total deafness. One week later reasonable pure-tone thresholds appeared but she still had total bilateral loss of speech discrimination. At that time contralateral acoustic reflexes were bilaterally absent, whereas ipsilateral acoustic reflexes and waves IV and V of the brainstem auditory evoked potential were bilaterally preserved. It is proposed that this patient's hearing deficit was due to inactivation of the ventral acoustic striae decussating in the trapezoid body. This case supports the contention that in humans the ventral pontine acoustic decussation carries most of the neural signals required for hearing and perhaps all the neural signals required for speech perception.

    A 60-year-old woman with a history of breast cancer presented with bilateral obstruction of bilaterally duplicated renal collecting systems secondary to extrinsic compression from metastatic pelvic lymphadenopathy. Bilateral JJ ureteric stents were inserted, resulting in some improvement of renal function but a failure to normalise completely. Repeat computed tomography demonstrated bilateral duplex collecting systems with persisting obstruction of the undrained moieties. Selective puncture was performed to decompress the obstructed renal moieties for bilateral nephrostomy catheter insertion. This allowed renal function to improve sufficiently for the patient to be discharged and commence chemotherapy. This is the first reported case of bilaterally obstructed partially duplicated collecting systems and it illustrates the importance of recognising anatomical variants to tailor treatment appropriately. It also highlights the important relationship between urology and interventional radiology in the management of such complex patients. PMID:26985816

    Simultaneous bilateral spontaneous pneumothorax (SBSP) occurred in a 16-year-old male. He presented with severe dyspnea. Chest X-ray showed bilateral pneumothorax. Computed tomography revealed bilateral apical bullas. Chest tubes were promptly inserted bilaterally. The patient underwent single-stage bilateral video-assisted thoracoscopic surgery( VATS). Bilateral bullectomy was performed sequentially. Saline poured in to test for air leakage did not escape to the opposite pleural cavity, suggesting no pleuro-pleural communication. Post-operative course was uneventful. A bilateral single-stage VATS by a conventional lateral approach with intra-operative patient repositioning is a safe, feasible and familiar technique for treatment of SBSP. PMID:24917168

    Bilateral anterior cruciate ligament (ACL) injuries are rare with incidence between 2 and 4%, and presently no definitive guidelines for proper management exist. Ideal treatment protocol remains controversial between a single-stage and two-stage bilateral ACL reconstruction. The purpose of this study is to evaluate the outcome of single-stage bilateral ACL reconstruction with hamstring tendon autografts in bilateral ACL injuries. A prospective study was undertaken including a total of 14 consecutive patients with bilateral ACL deficient knee who underwent single-stage bilateral ACL reconstruction with hamstring tendon autograft with a mean follow-up duration of 28 months (24-38 months). Functional outcomes were evaluated by range of movements, International Knee Documentation Committee (IKDC), Lysholm and Tegner activity score, and stability tests. The mean age was 30 years (range 18-42 years). Average duration of rehabilitation was 8 weeks. Time to return to full-time work and full sports was 5.6 weeks and 6.2 months, respectively. Clinical examination demonstrated full range of motion; a total of 12 patients (86%) had a negative Lachman test and 13 patients (93%) had a negative pivot shift at the final follow-ups. The mean IKDC evaluation score was 89 points, the mean Tegner activity score was 7 points, and the mean Lysholm knee score was 91 points. A total of 12 patients (86%) returned to their preinjury level of activity and an overall greater than 90% satisfaction rate was achieved. Single-stage bilateral ACL reconstruction using hamstring autografts is clinically safe, effective, and cost-effective with better patient compliance and with comparable functional outcome as opposed to two-stage ACL reconstructions.

    Abstract Although laparoscopy is a recognized operative approach to the management of renal masses, there is currently no standardized approach to manage bilateral synchronous renal masses. We present a case of synchronous bilateral renal masses, identified during work-up for flank pain, and managed simultaneously with laparoscopic partial nephrectomies. The patient is a 42-year-old Caucasian male found to have bilateral renal masses during evaluation for left flank pain. Cross-sectional imaging studies showed a 7.0 × 7.3 × 5.2 cm anterior, mid-to-lower pole mass on the left kidney and a 1.5 × 1.9 × 1.6 cm medial lower pole mass on the right kidney. He underwent bilateral laparoscopic partial nephrectomy at the same setting, with an uncomplicated postoperative course. Pathology report revealed clear cell renal-cell carcinoma (ccRCC) on both sides. He had normal renal function and no evidence of recurrence in the first 6 months of follow-up. This case demonstrates the possibility and safety of performing bilateral laparoscopic partial nephrectomies in one operative session. Our review of the literature supports the role of genetic counseling and the need for long-term surveillance in young patients having RCC.

    The aim of this report is to present a case of a patient with bilateral lacrimal gland abscesses in the course of dacryoadenitis. A 45-year-old female patient with a long history of cocaine abuse presented with bilateral bacterial dacryoadenitis and upper lid inflammation with purulent discharge from a palpebral wound of the right upper lid. The diagnosis was confirmed with microbiology culture and an orbital CT scan, which revealed lacrimal gland abscesses. The patient admitted to vigorous eye scratching, which we believe was the mechanism responsible for the process. The infection resolved on targeted antibiotic therapy. This is the first reported case of bilateral infectious dacryoadenitis produced in a self-inflicted mechanism in a cocaine addict. PMID:25208047

    Early diagnosis of this septic sacroiliitis is difficult because symptoms are nonspecific during the postpartum period. In this case we dicscuss about a patient with bilateral buttock pain unresolved with painkillers and rest, after an induction delivery. A 31-year-old woman was presented to our clinic on the second week of postpartum period with bilateral buttock pain. She was subfebrile and had no apparent abnormality on her pelvic X-ray. The pain was so severe that she was unable to walk properly. Sacroiliac MRI during the acute episode of pain showed bone marrow oedema and fluid within the bilateral sacroiliac joint. She was found seropositive for brucellosis and the patient completely recovered with antibiotherapy treatment. We stopped our patient from breastfeeding when the Rose Bengal test turned out positive. Brucella sacroiliitis should be considered in puerperium period women when buttock pain and difficulty in walking are present and pain is unresponsive to analgesics. PMID:26675497

    Among the rare cardiac tumors, myxoma, which is mostly located in the left atrium, is the most common type. Bilateral atrial myxoma is extremely rare, and requires urgent surgery. The authors report the case of a 34-year-old male, who presented with one month of right hemiparesis and aphasia and subsequently diagnosed with bilateral atrial myxoma based on transthoracic echocardiography. An urgent operation for intra-cardiac tumor removal was performed with the biatrial approach. Once a diagnosis of myxoma has been made, an urgent operation for tumor removal is necessary due to the risk of serious complications, including sudden death from normal blood flow obstruction.

We report a patient with bilateral psoas abscesses causing extensive pulmonary emboli through compression of the iliac vein. Case Report: A 47-year-old man presented with bilateral leg swelling over 4 weeks. Physical examination revealed a thin male with bilateral leg swelling, extending to the thigh on his left side. He had hemoglobin of 10.5 g/dl, leukocytosis of 16 000/ml, and an elevated D-dimer. A computed tomography (CT) angiogram of his chest showed extensive bilateral pulmonary emboli and infarcts. He remained febrile with vague flank pain, prompting a CT of his abdomen and pelvis that showed large, multiloculated, septated, bilateral psoas abscesses with compression of the left femoral vein by the left psoas abscess and a thrombus distal to the occlusion. Two liters of pus was drained from the left psoas abscess by CT-guidance, and although the Gram staining showed Gram-positive cocci in clusters, cultures from the abscess and blood were negative. A repeat CT showed resolution of the abscesses, and the drain was removed. He was discharged to a nursing home to complete a course of intravenous antibiotics and anticoagulation. Conclusions: Although the infectious complications of psoas abscesses have been described in the literature, the mechanical complications of bilateral psoas abscesses are lacking. It is important to assess for complete resolution of psoas abscesses through

    2016-06-01

    The bilateral filter is a non-linear filter that uses a range filter along with a spatial filter to perform edge-preserving smoothing of images. A direct computation of the bilateral filter requires $O(S)$ operations per pixel, where $S$ is the size of the support of the spatial filter. In this paper, we present a fast and provably accurate algorithm for approximating the bilateral filter when the range kernel is Gaussian. In particular, for box and Gaussian spatial filters, the proposed algorithm can cut down the complexity to $O(1)$ per pixel for any arbitrary $S$. The algorithm has a simple implementation involving $N+1$ spatial filterings, where $N$ is the approximation order. We give a detailed analysis of the filtering accuracy that can be achieved by the proposed approximation in relation to the target bilateral filter. This allows us to to estimate the order $N$ required to obtain a given accuracy. We also present comprehensive numerical results to demonstrate that the proposed algorithm is competitive with state-of-the-art methods in terms of speed and accuracy.

    A patient with cluster type headaches demonstrated bilateral and alternating ocular sympathetic dysfunction during a spontaneous as well as a nitroglycerin-induced attack. Biochemical evaluation revealed postganglionic pupillary dysfunction on the symptomatic side and preganglionic pupillary dysfunction contralaterally. These findings defy a simple explanation regarding a central or peripheral origin of the oculocephalic sympathetic dysfunction. PMID:8262788

    Obturator hernia (OH), a rare type of hernia, is associated with high morbidity and mortality. Diagnosis is often delayed as clinical symptoms are typically non-specific. OH is frequently associated with other occult inguinopelvic herniae. Early diagnosis is vital to decrease morbidity and mortality. We report the case of a 75-year-old woman who presented to the surgical outpatients' department with non-specific bilateral groin pain radiating to the thighs. CT of the pelvis demonstrated bilateral OH with no radiological evidence of bowel obstruction. Semiurgent elective laparoscopic total extraperitoneal mesh repair was performed. Intraoperative findings confirmed bilateral obturator herniae as well as incidental bilateral femoral herniae. This case highlights the need for a high index of suspicion for such concomitant hernias that, in the presence of OH, may only be identified intraoperatively. PMID:27113790

    2014-01-01

    Introduction: Stress fractures are overuse injuries most commonly seen in athletes, military recruits, and individuals with endocrine abnormalities. It has been demonstrated that chronic cases of anterior tibial stress fractures refractory to conservative management respond well to intramedullary nailing. To our knowledge, only one report has been published concerning patients with bilateral tibial stress fractures treated with bilateral intramedullary nailing. All patients in the series were high-level athletes. We present the case of a non-athletic patient with chronic bilateral tibial stress fractures and associated deformity successfully treated with bilateral intramedullary nails. Case Report: A 23-year-old Caucasian female full-time student presented with chronic bilateral shin pain for approximately five years. She had failed an extensive regimen of conservative management. She was diagnosed with chronic bilateral tibial stress fractures based on history, physical examination, and radiologic findings. She subsequently underwent sequential intramedullary nailing of her tibiae. Both tibiae were in valgus alignment; however, this did not preclude nail placement. The nails deformed upon insertion into the sclerotic canals to conform to the deformation. Post operatively the tibiae united and patient was relieved of her symptoms. Conclusion: Bilateral intramedullary nailing of chronic bilateral tibial stress fractures should be considered as a treatment option for all patients, not just high-level athletes, who fail a trial of conservative management. Additionally, mild to moderate tibial malalignment does not necessarily preclude tibial nailing as the smaller nails placed in sclerotic canals will likely deform on insertion and conform to the canal.

    2009-01-01

    Upper extremity hemiparesis is the most common post-stroke disability. Longitudinal studies have indicated that 30-66% of stroke survivors do not have full arm function 6 months post-stroke. The current gold standard for treatment of mild post-stroke upper limb impairment is constraint-induced therapy but, because of the inclusion criteria, alternative treatments are needed which target more impaired subjects. Bilateral arm training has been investigated as a potential rehabilitation intervention. Bilateral arm training encompasses a number of methods including: (1) bilateral isokinematic training; (2) mirror therapy using bilateral training; (3) device-driven bilateral training; and (4) bilateral motor priming. Neural mechanisms mediating bilateral training are first reviewed. The key bilateral training studies that have demonstrated evidence of efficacy will then be discussed. Finally, conclusions are drawn concerning clinical implications based on the reviewed literature. PMID:19517519

  5. 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

    Many types of bilateral control architectures to transmit force sensation have been proposed. Some control methods obtain good performance. Operationality is not satisfactory, however, when these methods are implemented in bilateral systems with large inertia and friction force. In this paper, a novel bilateral control method is proposed to improve operationality of bilateral systems with large inertia and friction force. The proposed method is compared with a conventional method, and the effectiveness of the proposed method is demonstrated by coordinate transformation and experiments.

    Infectious orbital complications after strabismus surgery are rare. Their incidence is estimated to be 1 case per 1,100 surgeries and include preseptal cellulitis, orbital cellulitis, subconjunctival and sub-Tenon's abscesses, myositis, and endophthalmitis. This report describes the case of an otherwise healthy 3-year-old boy who underwent bilateral medial rectus recession and disinsertion of the inferior obliques. A few days after surgery, the patient presented with bilateral periorbital edema and inferotemporal chemosis. A series of CT scans with contrast revealed inferotemporal orbital collections OU. The patient immediately underwent transconjunctival drainage of fibrinous and seropurulent collections in the sub-Tenon's space and experienced rapid improvement a few days later. The patient is reported to be in stable condition in a follow-up examination performed more than a year after the reported events. PMID:24896771

    Introduction Isolated traumatic fractures of both Patellae, occurring at the same time, in an otherwise healthy person, are very rare. The Patella, as a subcutaneous and a cancellous bone, is vulnerable to injury. However, simultaneous injury to both Patellae without the involvement of any other bony injuries occurs infrequently, and only a few cases have been reported in the literature. Case Presentation We report a rare case of isolated, traumatic bilateral Patella fracture with unusual fracture patterns and briefly review the literature. Conclusions In simultaneous bilateral Patella fractures, good functional outcome can be expected following a stable surgical fixation and a structured rehabilitation regime. However, personality of the fracture determines salvage versus sacrifice of the Patella. PMID:27218047

    Although traumatic injury of the facial nerve is a relatively common condition in neurosurgical practice, bilateral lesions related to fracture of temporal bones are seldom seen. We report the case of a 38-year-old patient admitted to Intensive Care Unit after severe head trauma requiring ventilatory support (Glasgow Coma Scale of 7 on admission). A computed tomography (CT) scan confirmed a longitudinal fracture of the right temporal bone and a transversal fracture of the left. After successful weaning from respirator, bilateral facial paralysis was observed. The possible aetiologies for facial diplegia differ from those of unilateral injury. Due to the lack of facial asymmetry, it can be easily missed in critically ill patients, and both the high resolution CT scan and electromyographic studies can be helpful for correct diagnosis.

MRI demonstrated mild bilateral optic nerve enhancement. Humphrey 30-2 visual field testing showed bilateral seco-central scotomas. MR venogram, visual evoked potentials, preeclampsia workup, and serum blood tests for folate, B6, B12, Toxoplasmosis, Bartonella, Lyme disease, ACE levels, RPR, and LFTs were all within normal limits. After one-time treatment of IV 125 mg methylprednisolone and spinal tap, visual acuity improved to 20/20 OD and 20/20 OS. PMID:23305442

    We report a case of bilateral orbital hemorrhage as a complication of peribulbar anesthesia in a 78 year old man. Initially, unilateral orbital hemorrhage occurred but quickly spread to the contralateral side. Neuroophthalmological assessment revealed a proptosed tense globe with normal retinovascular findings. Visual acuity was adversely affected and this was conservatively managed with no lasting ophthalmic sequela. This patient’s case was reported as it illustrates an unusual complication of bilateral spread of orbital hemorrhage secondary to peribulbar anesthesia. It highlights how early ophthalmic assessment can ensure a good visual outcome in the setting of appropriate ophthalmic monitoring. The mechanisms of orbital hemorrhage spread and appropriate management options are discussed. PMID:27013899

    Two cats that developed bilateral calcaneal stress fractures are reported. One cat developed lameness associated with incomplete fractures at the base of both calcanei, both of which progressed to acute, complete fractures 2 months later. The second cat presented with acute complete calcaneal fracture, with evidence of remodelling of the contralateral calcaneus, which subsequently fractured two years later. The calcaneal fractures were successfully stabilised with lateral bone plates in each case. Stress fractures were suspected because of the bilateral nature, the simple and similar configuration, the consistent location of the fractures, the absence of other signs of trauma in both cases and the suspected insidious onset of the lameness. The feline calcaneus is susceptible to stress fracture, and cats presenting with calcaneal fractures without evidence of trauma should be evaluated for concurrent skeletal pathology. PMID:25929309

    Purpose To report the clinical, confocal scan, and histopathologic features of nocardia keratitis in a patient who developed bilateral infection following photorefractive keratectomy (PRK). Case Report A 23-year-old woman underwent bilateral PRK for low myopia. On postoperative day 3, dense central stromal infiltrates were noticed in both eyes. Empirical antibiotic therapy was initiated which was converted into specific therapy after a definite diagnosis was made based on clinical features and confirmed by confocal scan and histopathologic findings. Clinical and confocal scan features were consistent with the diagnosis of Nocardia keratitis, and topical 2% amikacin eye drops were started. Because of poor response to medical therapy, lamellar keratectomy was performed in both eyes which shortened the treatment course. Histopathologic examination reconfirmed the initial diagnosis. Conclusion Familiarity with clinical and confocal scan features facilitates early diagnosis of Nocardia keratitis leading to proper management and hence a rapid therapeutic response. PMID:23275825

    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 unknown iatrogenic seed

    2015-01-01

    Patient: Male, 21 Final Diagnosis: Idiopathic bilateral external jugular vein thrombosis Symptoms: Face engorgement • neck swelling Medication: — Clinical Procedure: None Specialty: Hematology Objective: Unknown ethiology Background: 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. Case Report: 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. Conclusions: 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

    To evaluate the analgesic efficacy of local anesthetic infiltration, 20 parturients scheduled for elective minilaparotomy and bilateral tubal ligation with either spinal or epidural anesthesia participated in this prospective, randomized, controlled, double-blind trial. All patients received intravenous (iv) metoclopramide 10 mg and ketorolac 60 mg intraoperatively, as well as preincisional infiltration of the infraumbilical skin incision with 0.5% bupivacaine. Infiltration of bilateral uterine tubes and mesosalpinx was performed either with 0.5% bupivacaine (n = 10) or isotonic sodium chloride solution (n = 10). Intravenous meperidine (25 mg every 3 minutes as needed) was given to treat pain in the postanesthesia care unit (PACU). The total amount of meperidine administered in the PACU was significantly larger in the saline group than in the bupivacaine group. Pain scores at 30, 45, 60, 75, and 90 minutes postoperatively and on the 7th postoperative day were significantly lower in the bupivacaine group than in the saline group. During tubal ligation, infiltration of uterine tubes and mesosalpinx with 0.5% bupivacaine significantly enhanced analgesia both immediately postoperatively and on the 7th postoperative day compared with infiltration with sodium chloride. In conclusion, this study proved that during bilateral tubal ligation with either spinal or epidural anesthesia, preemptive analgesia using iv ketorolac, iv metoclopramide, and infiltration of the incised skin and uterine tubes with 0.5% bupivacaine can eliminate pain, nausea, vomiting, or cramping and maintain good analgesia for 7 days postoperatively.

    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.

    We report here a case study of a rare neurological patient with bilateral brain damage encompassing a substantial portion of the so-called “limbic system.” The patient, Roger, has been studied in our laboratory for over 14 years and the current article presents his complete neuroanatomical and neuropsychological profiles. The brain damage occurred in 1980 following an episode of herpes simplex encephalitis. The amount of destroyed neural tissue is extensive and includes bilateral damage to core limbic and paralimbic regions, including the hippocampus, amygdala, parahippocampal gyrus, temporal poles, orbitofrontal cortex, basal forebrain, anterior cingulate cortex, and insular cortex. The right hemisphere is more extensively affected than the left, although the lesions are largely bilateral. Despite the magnitude of his brain damage, Roger has a normal IQ, average to above average attention, working memory, and executive functioning skills, and very good speech and language abilities. In fact, his only obvious presenting deficits are a dense global amnesia and a severe anosmia and ageusia. Roger's case presents a rare opportunity to advance our understanding of the critical functions underlying the human limbic system, and the neuropsychological and neuroanatomical data presented here provide a critical foundation for such investigations.

    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.

    Among 238 patients with bilateral trigeminal neuralgia(TN)who visited our hospital between April 2007 and June 2014, 5(2%)were surgically treated by microvascular decompression(MVD). The initial symptom was on the right side in four and on both sides in one patient. Intervals between the initial and second onset on the other side(left)were two months, and four, six, and eight years. None of the patients showed involvement of the first branch of the trigeminal nerve. The patients with bilateral TN were younger than the 154 patients with unilateral TN who were treated surgically by MVD in this period(45 vs. 65 years), and the bilateral TN patients predominantly were women(4/5 vs. 99/154). In the surgical field, the trigeminal nerve and root entry zone were compressed more by veins in the bi lateral TN patients than in the unilateral TN(4/5 vs. 60/154, respectively)patients. We could not identify any differences in MRI CISS before versus after the onset of left trigeminal neuralgia, suggesting that compression is not the sole cause of the symptom. PMID:25672553

    Caudate strokes comprise only a small proportion of all subtypes of strokes. Bilateral caudate infarcts are even rarer and only a few cases have been reported in the literature. We report an 86-year-old woman with bilateral caudate infarcts. She had no past medical history of note. She presented with headache for several days and drowsiness on day of admission. Clinical examination revealed abulia, inability to comprehend or verbalize (acute mutism), right-sided neglect and right-sided hemiparesis. Computed tomographic (CT) scan brain revealed decreased attenuation in both heads of both caudate nuclei with extension across the anterior limb of both internal capsules to involve the lentiform nuclei. Echocardiography showed aortic valve sclerosis, mild mitral and aortic regurgitation and normal left ventricular function. Carotid ultrasound revealed mild stenosis of proximal right internal carotid and left distal common carotid and adjacent proximal internal carotid arteries. She showed initial improvement in the first week, but subsequently had a progressive downward course despite rehabilitation and died 44 days after her stroke. A patient with bilateral caudate infarcts is likely to have poor prognosis for rehabilitation and survival. PMID:10561773

    Acute spontaneous compartment syndrome of the forearm is rarely reported in the literature. It is typically associated with trauma or thromboembolism in the acute setting and repetitive exertional stress in the chronic setting. However it is rare for it to present bilaterally with no apparent underlying cause. We report the case of a young 31-year-old lady who presented to our Emergency Department with bilateral compartment syndrome of the forearm. Her presenting complaints included acute severe pain and swelling of the forearms bilaterally, with a decreased range of movement of the wrist and fingers. She also complained of numbness in all fingers. She had no history of recent trauma and ultrasound scans showed no evidence of vascular compromise. Past medical history was notable only for idiopathic hypertension and coeliac disease. The patient was taken to theatre urgently where flexor and extensor compartments and carpal tunnel were decompressed. Pronator Teres was found to be dusky initially but turned pink after decompression. All other muscles were normal. An interesting fact of this case was that combination of the high compartment pressures and anaesthetic related hypotension caused the forearm pulses to become impalpable at induction, these returned intra-operatively. The patient has been seen in the outpatient department following discharge. She is well apart from some mildly reduced grip strength in her right hand likely due to carpal tunnel decompression. No cause was found for the scenario after extensive medical investigation. PMID:24641749

    Purpose The management of prenatally detected bilateral ureteropelvic junction obstruction (UPJO) remains controversial. We attempted to develop a treatment plan for patients with severe bilateral UPJO. Materials and Methods We evaluated the records of 13 patients with prenatally diagnosed grade 3 or more bilateral hydronephrosis that led to the postnatal diagnosis of severe bilateral UPJO. Ultrasonography and 99mtechnetium mercaptoacetyltriglycine (99mTc-MAG3) renal scans were performed within 1 month. Four renal units had grade 3 and 22 had grade 4 hydronephrosis. All 13 patients were managed by unilateral pyeloplasty, and the patients' mean age was 3 months. At 1 month postoperatively, we decided whether delayed surgery in the opposite renal unit was necessary according to the findings of ultrasonography and 99mTc-MAG3 scans. Results Of 13 patients, 11 underwent initial pyeloplasty on renal units with more severe hydronephrosis or lower relative renal function (RRF) on 99mTc-MAG3 scans. The remaining 2 patients simultaneously underwent percutaneous nephrostomy on renal units with a lower RRF and initial pyeloplasty on renal units with a higher RRF. In 5 patients, contralateral hydronephrosis had spontaneously improved at 1 month postoperatively, and 8 patients underwent delayed contralateral pyeloplasty at 2 months postoperatively. Conclusions In children with severe bilateral UPJO, the non-operated renal units with grade 3 and some with grade 4 hydronephrosis improved spontaneously after unilateral pyeloplasty. Therefore, delayed pyeloplasty of the opposite side should be considered at 1 month following initial pyeloplasty. PMID:20856652

    We present a 54 year old male patient who had a bilateral lung transplant sixteen years ago for Alpha-1 Antitrypsin Deficiency-related emphysema. He was referred for flexible bronchoscopy with transbronchial biopsies to evaluate new mild exertional dyspnea and worsening of his FEV1. Eight transbronchial biopsies were done from the right middle lobe and the right lower lobe. Post procedure he developed bilateral pneumothoces that required emergent bilateral pleural ‘pigtail’ catheters. To our knowledge, this is the first reported case of bilateral pneumothoraces that developed after a unilateral procedure in a bilateral lung transplant recipient relatively late after the transplant.

    Simultaneous bilateral spontaneous pneumothorax (SBSP) is a very rare life-threatening condition that requires rapid diagnosis and treatment. Most cases are secondary to various underlying lung pathology but a primary SBSP may occur due to rupture of subpleural blebs or bullae. Surgery via an open or minimally invasive approach provides definitive treatment and can be undertaken as a staged or simultaneous procedure. We report our experience with two such rare cases utilizing a single stage minimally invasive bilateral video assisted thoracoscopic (VATS) approach. The pathogenesis of this rare condition and intra-operative technical considerations for a successful outcome are discussed. PMID:22822653

    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. PMID:27186561

    Bilaterality is uncommon in Wilms' tumor, being present in 4% to 8% of the cases. We report the combined experience of two children's hospitals in one city over a 20-year period. We encountered nine cases of synchronous bilateral nephroblastoma (National Wilms' Tumor Study 3, stage V). Age at diagnosis ranged from 9 to 41 months (mean 23 months). There were five girls and four boys. Associated findings include nephroblastomatosis in three cases (33%), one of which also had a familial history; undescended testis in two cases; and minor anomalies in two other cases. Surgical treatment consisted of unilateral nephrectomy with contralateral partial nephrectomy or tumorectomy in six cases, nephrectomy with contralateral biopsy only in two cases, and the other patient had bilateral biopsies initially, followed at a later date by partial nephrectomy on one side. All patients received chemotherapy; actinomycin D (AMD) only was used in the oldest case, vincristine and AMD in five cases, to which was added cyclophosphamide in one case and adriamycin in two. Seven patients received radiation therapy. Seven out of the nine patients survived more than 2 years (77%); five are well, off chemotherapy, with no evidence of disease from 4 to 11 years after diagnosis. Two patients suffered from chronic renal failure and one died from complications after renal transplantation more than 19 years after diagnosis. The two patients who died from their disease presented with more advanced tumor. Therefore, the agressiveness of multimodal therapy can be tailored according to stage and histology, and effective chemotherapy allows maximal preservation of renal parenchyma in patients with stage I and II tumors.

    Discoid medial meniscus is a relatively rare pathology of the knee joint, with bilateral cases even rarer. Herein, we report the case of a 25-year-old man diagnosed with discoid medial meniscus in the right knee with a horizontal tear. Increased cupping of the medial condyle of the tibia, widening of the medial joint space and the presence of discoid meniscus in the right knee prompted investigation of the asymptomatic left knee with magnetic resonance imaging. The contralateral asymptomatic knee also showed evidence of discoid medial meniscus. The symptomatic knee was successfully treated by arthroscopic partial meniscectomy, with excellent functional outcome. PMID:25273941

    An adolescent presented with a rhinosinusitis complicated with bilateral jugular veins and left superior ophthalmic vein thrombosis and respiratory distress with pulmonary hypertension. Blood culture was positive for Haemophilus influenzae and sinus puncture for Streptococcus constellatus. Evolution was under control after 1 week of appropriate antibiotherapy, antithrombotic and anti-inflammatory treatment. He had no neurologic, respiratory or ophthalmologic sequelae 6 months later. Despite lack of pharyngitis or isolation of anaerobic species on blood cultures, the picture was considered compatible with Lemierre syndrome. The risk for such a complication should be considered in cases of severe otorhinolaryngologic infection in young adults. PMID:14643536

    Achondroplasia is the most common skeletal dysplasia and it combines various complications with normal longevity. Hearing disturbance due to otitis media or an ossicular anomaly is one of the most common complications. Conductive hearing loss is suggested as the most common form of hearing loss. Temporal bone and middle ear structures are distorted in achondroplasia because of rotational change of the skull base. Authors experienced a case of an achondroplastic patient with bilateral hearing disturbance. We faced making a potential mistake during the previous operation but a favorable postoperative result occurred. Our experience could be helpful to other clinicians who face achondroplastic patients.

    Despite the high incidence of prostate carcinoma, metastases of the uvea are very rare and bilateral localization is even more. We report here the case of a 77-year-old man diagnosed with a metastatic prostate carcinoma. Two months later, he presented a decreased vision in his right eye and blurred vision in the left eye relevant to metastatic lesion on his right iris and left choroidal metastasis.

    We report the case of a 14-year-old boy with bilateral congenital perisylvian syndrome as evidenced by polymicrogyria in the left and right frontotemporal regions, pseudobulbar paresis, seizures, and spastic diplegia. This is the first description of comprehensive neuropsychological assessment in a child with this syndrome. The results reflect significant impairments in auditory processing and independent learning and retention, but relatively preserved cognitive performance on interactive tasks involving frequent feedback and redirection. The findings are interpreted in the context of the neuropathology of this syndrome, with an emphasis on pragmatic implications for rehabilitation. PMID:18618376

    The observational case describes bilateral recurrent keratoconus in corneal transplants performed in a patient with self-induced keratoconus secondary to compulsive eye rubbing. Slitlamp findings demonstrated corneal stromal thinning and scarring in the patient's right eye and temporal corneal hydrops in his left eye. Videokeratography of the right eye confirmed the presence of corneal steepening and irregular astigmatism, consistent with the diagnosis of keratoconus involving each transplant. Together with the history of ongoing compulsive eye rubbing, these findings support the concept that chronic mechanical trauma to the cornea may contribute to the development of keratoconus.

    The authors report a case of congenital bilateral eversion of the eyelids with secondary conjunctival prolapse in a 4-hour-old neonate. Conservative treatment with hypertonic normal saline, lubricants, antibiotics, and padding was instituted. No surgery was performed. Complete eye opening was achieved by the 10th day after birth. Medical management is advantageous in that it is inexpensive, noninvasive, and can be performed even in a center with poor surgical facilities, as is commonly encountered in developing countries. The sociopsychological aspect of the disease, possible pathophysiology, and treatment are discussed. PMID:19043951

    1982-03-01

    Observation of a case of progressive bilateral parietal thinning within a period of 14 years induced us to study skull films of 3 636 consecutive patients. Parietal thinning was found in 86 patients (2.37%). It was more common in women, with a sex ratio of 1:1.9. The mean age of the females was 72 years, and that of the males 63 years. Previous skull films of 25 of these patients were available and showed progression in 10. It is concluded that parietal thinning is a slowly progressive disease of middle-aged and old patients and is not an anatomical variant or congenital dysplasia of the dipole.

    Primary aldosteronism due to unilateral aldosterone-producing adenoma (APA) is a surgically curable form of hypertension. Bilateral APA can also be surgically curable in theory but few successful cases can be found in the literature. It has been reported that even using successful adrenal venous sampling (AVS) via bilateral adrenal central veins, it is extremely difficult to differentiate bilateral APA from bilateral idiopathic hyperaldosteronism (IHA) harbouring computed tomography (CT)-detectable bilateral adrenocortical nodules. We report a case of bilateral APA diagnosed by segmental AVS (S-AVS) and blood sampling via intra-adrenal first-degree tributary veins to localize the sites of intra-adrenal hormone production. A 36-year-old man with marked long-standing hypertension was referred to us with a clinical diagnosis of bilateral APA. He had typical clinical and laboratory profiles of marked hypertension, hypokalaemia, elevated plasma aldosterone concentration (PAC) of 45.1 ng dl−1 and aldosterone renin activity ratio of 90.2 (ng dl−1 per ng ml−1 h−1), which was still high after 50 mg-captopril loading. CT revealed bilateral adrenocortical tumours of 10 and 12 mm in diameter on the right and left sides, respectively. S-AVS confirmed excess aldosterone secretion from a tumour segment vein and suppressed secretion from a non-tumour segment vein bilaterally, leading to the diagnosis of bilateral APA. The patient underwent simultaneous bilateral sparing adrenalectomy. Histopathological analysis of the resected adrenals together with decreased blood pressure and PAC of 5.2 ng dl−1 confirmed the removal of bilateral APA. S-AVS was reliable to differentiate bilateral APA from IHA by direct evaluation of intra-adrenal hormone production. PMID:26538381

    Bilateral simultaneous fracture dislocation of the talus is a very rare injury. It occurs usually following high-velocity injuries. We report a 45-year-old man who presented with bilateral talar fracture dislocation following a heavy stone falling on him. On his right side, he had open talus dislocation with lateral process fracture and on his left side he had closed talar neck fracture dislocation. He underwent immediate debridement and external fixator application for his right side and open reduction and internal fixation for his left talus. At the end of 34 months’ follow-up, he was able to walk up to 2 km without pain. His ankle range of movements were restricted bilaterally. Radiographs revealed bilateral avascular necrosis with right side showing complete collapse. We present this case for its rare presentation of bilateral talar fracture dislocation with bilateral avascular necrosis with sequential radiographs. PMID:25155493

    The diagnostic strategy for asymptomatic patients with persistent bilateral bilar adenopathy often involves invasive procedures. The authors used Bayesian analysis to: (1) estimate the relative prevalences of diseases causing bilateral bilar adenopathy; (2) assess changes in the prevalence of disease by race, the presence of other clinical symptoms, and geography; and (3) determine the value of relevant noninvasive tests, including the angiotensin-converting enzyme (ACE) assay, gallium scan, and purified protein derivative (PPD), in order to assess when a strategy of watchful waiting is appropriate. The analysis indicated that the ACE assay, particularly when paired with the PPD, can identify many patients who might safely be managed without immediate invasive biopsy. Patients who are ACE+ and PPD- have an estimated probability of sarcoidosis of 0.95 or greater; patients who are ACE- and PPD+ have a probability of tuberculosis of 0.86 if black, 0.79 if white. In contrast, gallium scanning has no diagnostic role in this clinical situation. Bronchoscopic or mediastinoscopic biopsy has a limited role for patients who are ACE+ PPD- or ACE- PPD+ because of limited sensitivity. Patients who are both ACE- and PPD-, particularly if white, may have a high enough risk of lymphoma to consider invasive biopsy.

    The paper presents the results of gait parameters as a function of unilateral weight. The object of the research was a woman walking on a stationary surface and carrying in his hand weights from 0 to 15 kg. Her movement was recorded by 6 cameras recording the location of 34 markers placed at appropriate points in the body. 3D reconstruction was performed for each of the reflecting markers. Tested signals were changes in the value the joint angles of ankle, knee and hip. On the basis of about 6 cycles of movement of each load, a model for the average gait cycle was developed. The result of the experiments are graphs of changes the joint angles as a function of time, bilateral cyclograms, synchronized bilateral cyclograms and regression lines. The conclusion of the study is to determine how one-sided load affects gait asymmetry. Simple and easy to interpret method of presentation of results were also shown. Studies were conducted using VICON system.

    At present, the care of women at increased risk of developing breast cancer poses a clinical dilemma and remains an area of controversy. A number of investigators have addressed the pros and cons of prophylactic mastectomy versus close follow-up, utilizing annual mammography, semiannual or even more frequent physical examinations of the breast, and proficient monthly breast self-examinations. Recent efforts to isolate a gene (BRCA1) on chromosome 17q12-21 raise additional concerns about the management of women testing positive for BRCA1 mutations. These women are estimated to have an 85% lifetime risk of developing breast cancer. Testing for BRCA1 mutation carriers may soon be available for population screening. This article describes preliminary studies investigating health care provider and patient perceptions of bilateral prophylactic mastectomy. In addition, a number of research questions remain regarding the efficacy and utilization of bilateral prophylactic mastectomy as a treatment option for women at increased risk of developing breast cancer. These women include those testing positive for BRCA1 mutations. In addition, women with a strong family history opting against testing for BRCA1 mutations may express interest in surgery.

    Bilateral Fuchs uveitis associated with vitreous infiltration and posterior segment involvement requires a thorough diagnostic evaluation. The lack of well-defined diagnostic criteria makes identification of this entity difficult. The aim of this case report was to present the characteristics of a patient with atypical Fuchs uveitis and the procedures needed to rule out the differential diagnosis with specific attention to the utility of in vivo confocal microscopy (IVCM). Case Report One case of chronic bilateral uveitis with severe vitreous opacities is presented. After extensive systemic workup, including vitrectomy, the case had no identifiable systemic etiology. IVCM of the cornea revealed the presence of dendritiform keratic precipitates. Conclusion The diagnosis of Fuchs uveitis is based on clinical findings as no confirmatory laboratory tests are available. A high index of suspicion is key to an early diagnosis, especially in the cases with vitreous opacities and posterior segment manifestations. Auxiliary tests such as IVCM may aid the clinician in the diagnosis of Fuchs uveitis. PMID:26483668

    Motivation is drawn from the need to determine the sensory cues that animals such as blue crabs and lobsters use to track chemical odor plumes to locate food or mates. Major steps forward with this difficult problem can only be achieved through an appreciation of the spatial and temporal variation of concentration fields and the information content available to a forager in the plume. Here we discuss the usefulness of bilateral comparison to an animal tracking a turbulent plume. Instantaneous concentration fields of a chemical plume diffusing in a fully-developed turbulent open channel flow are measured using planar laser-induced fluorescence (PLIF). The plume is released iso-kinetically 25 mm above the smooth bed (z+ = 90), thus transport is mainly due to advection and ambient turbulence. A spatial correlation function in the spanwise direction is a dramatic indicator of the relative position of the centerline and distance from the source. The relative direction of the plume centerline can be estimated from an instantaneous bilateral comparison provided the sensors are separated by a distance that is relatively large compared to the spanwise integral length scale based on the spatial correlation function.

    Background. Despite advances in surgical repair of hiatus hernias, there remains a high radiological recurrence rate. We performed a novel technique incorporating bilateral oesophageal fixation and evaluated outcomes, principally symptom improvement and hernia recurrence. Methods. A retrospective study was performed on a prospective database of patients undergoing hiatus hernia repair with bilateral oesophageal fixation. Retrospective and prospective quality of life (QOL), PPI usage, and patient satisfaction data were obtained. Hernia recurrence was assessed by either barium swallow or gastroscopy. Results. 87 patients were identified in the database with a minimum of 3 months followup. There were significant improvements in QOL scores including GERD HRQL (29.13 to 4.38, P < 0.01), Visick (3 to 1), and RSI (17.45 to 5, P < 0.01). PPI usage decreased from a median of daily to none, and there was high patient satisfaction (94%). 57 patients were assessed for recurrence with either gastroscopy or barium swallow, and one patient had evidence of recurrence on barium swallow at 45 months postoperatively. There was an 8% complication rate and no mortality or oesophageal perforation. Conclusions. This study demonstrates that our technique is both safe and effective in symptom control, and our recurrence investigations demonstrate at least short term durability. PMID:26065030

    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.

    2015-01-01

    This is a report of one case of bilateral acetabular rim fracture in association with femoroacetabular impingement (FAI), which was treated with a hip arthroscopic procedure, performing a partial resection, a labral reinsertion, and a subsequential internal fixation with cannulated screws. Up to date, there are in the literature only two reports of rim fracture and “os acetabuli” in association with FAI. In the case we present, the pincer and cam resection were performed without complications; the technique used was published previously. With this technique the head of the screw lays hidden by the reattached labrum. We removed partially the fractured rim fragment and the internal fixation of the remaining portion was achieved with a screw. In the event of a complete resection of the fragment, it would have ended with a LCE angle of 18° and a high probability of hip instability. We believe that this bilateral case helps establish the efficacy and reproducibility of the technique described by Larson. PMID:25722907

    Case series Patient: Male, 44 • Male, 58 Final Diagnosis: Soft tissue sarcomas Symptoms: Discomfort • swelling Medication: — Clinical Procedure: Image guided biopsy • metastatic work up • neoadjuvant radiotherapy • radical resection Specialty: Surgery Objective: Rare disease Background: Soft tissue sarcomas (STS) account for approximately 1% of adult malignancies, with 50 to 60% occurring in the extremities. Liposarcoma is the most common type of STS and represent about 20% of total adult sarcomas. There are rare syndromes associated with increased risk of developing STS. Further, chemical compounds such as chlorinated phenols and a few chemotherapeutic drugs have been linked to STS, along with ionizing radiation. Nevertheless, the etiology is uncertain for most of these lesions. Case Report: This report details 2 cases of metachronous bilateral STS of the lower extremities. The first of these presented as a local recurrence of a previously resected right thigh liposarcoma and a new liposarcoma in the left thigh. As mentioned above, among the different subtypes of STS, liposarcoma has the highest tendency for multifocality. The second patient had multifocal metachronous leiomyosarcoma with lung metastases occurring simultaneously with the second presentation. Leiomyosarcoma is another subtype reported to present with multi-focal disease. Conclusions: Despite the rarity of bilateral lesions, their occurrence should not be overlooked in the initial diagnosis and follow-up of the initially detected tumor. Early detection can affect patient survival because their presence predicts unfavorable outcomes. PMID:26744032

    Among infertile men, a diagnosis of unilateral varicocele is made in 90% of varicocele cases and bilateral in the remaining varicocele cases. However, there are reports of under-diagnosis of bilateral varicocele among infertile men and that its prevalence is greater than 10%. In this prospective study, we aimed to examine the differentially expressed proteins (DEP) extracted from spermatozoa cells of patients with bilateral varicocele and fertile donors. Subjects consisted of 17 men diagnosed with bilateral varicocele and 10 proven fertile men as healthy controls. Using the LTQ-orbitrap elite hybrid mass spectrometry system, proteomic analysis was done on pooled samples from 3 patients with bilateral varicocele and 5 fertile men. From these samples, 73 DEP were identified of which 58 proteins were differentially expressed, with 7 proteins unique to the bilateral varicocele group and 8 proteins to the fertile control group. Majority of the DEPs were observed to be associated with metabolic processes, stress responses, oxidoreductase activity, enzyme regulation, and immune system processes. Seven DEP were involved in sperm function such as capacitation, motility, and sperm-zona binding. Proteins TEKT3 and TCP11 were validated by Western blot analysis and may serve as potential biomarkers for bilateral varicocele. In this study, we have demonstrated for the first time the presence of DEP and identified proteins with distinct reproductive functions which are altered in infertile men with bilateral varicocele. Functional proteomic profiling provides insight into the mechanistic implications of bilateral varicocele-associated male infertility. PMID:25999357

  2. Bilateral Trade Flows and Income Distribution Similarity

    PubMed Central

    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

    INTRODUCTION Gorlin syndrome (GS), also known as nevoid basal cell carcinoma syndrome (NBCCS), is a rare hereditary, autosomal dominant disease that affects various systems. Its prevalence is estimated at 1/57,000 to 1/256,000 of the population. It is characterized by basal cell carcinomas, multiple odontogenic keratocysts, skeletal abnormalities and ovarian fibroma, among other disorders. PRESENTATION OF CASE To report the case of a young patient with Gorlin syndrome and bilateral ovarian fibroma. DISCUSSION A 20-year old patient with Gorlin syndrome presented with facial asymmetry, broad nasal root, dental abnormalities, micrognathism, convergent strabismus, multiple pigmented lesions on the trunk and face, pectus excavatum, kyphoscoliosis and a palpable mass in the abdomen occupying the entire pelvic region. CONCLUSION Gorlin–Goltz syndrome is a hereditary pathology that includes numerous clinical manifestations. Diagnosis is clinical and genetic confirmation is unnecessary. PMID:22771908

    1995-12-01

    The paper describes the implementation of shared control in a force reflecting telerobotic system which has been carried out during the EC TELEMAN project INGRID. The experimental facility which has been developed at Newcastle comprises a Puma 762 robot which can be manually teleoperated by a Puma 260 robot, functioning as a generalized bilateral (or force reflecting) controller. The slave robot has been configured to support several autonomous force controlled tasks, which have been developed specifically for repair and maintenance operations in nuclear and/or other hazardous environments. The control architecture is based on a network of parallel processors, and the man-machine interface provides `soft-switching' of any axis to facilitate mixed mode and shared control which can be configured in both teleoperator and task based modes. A graphic display is also included to provide a visual indication of the magnitude of forces/torques exerted at the tool/environment interface.

    A 40-year-old male paddy field worker was referred for exertional shortness of breath and non-productive cough for 4 years. He had been treated for pulmonary tuberculosis twice. Chest radiograph showed extensive bilateral nodular opacities ("sandstorm-like") in the middle and lower lobe. Pulmonary function tests revealed a restrictive ventilatory defect. High resolution CT showed widespread nodular infiltration with "crazy paving" appearance and interrupted black pleura sign. This was confirmed as pulmonary alveolar microlithiasis (PAM) by trans-bronchial lung biopsy, which showed normal respiratory lining epithelium with dilated alveolar spaces containing many calcific bodies, some of which showed concentric calcification. The possibilities of silicosis (due to exposure to husk) and tuberculosis, both of which can mimic PAM clinically and radiologically, made this case a diagnostic challenge. PMID:21686505

    A 57-year-old otherwise healthy woman presented with painless binocular vision loss 1 week after direct application of radiofrequency energy to her orbits. She had no light perception bilaterally. Pupils were dilated and not reactive to light. Fundoscopic exam initially showed optic disc swelling in the right eye and a normal-appearing disc in the left eye. Magnetic resonance imaging of the brain and orbits showed gadolinium enhancement of both intraorbital optic nerves. She underwent a course of high-dose steroid treatment without recovery of vision. Optic discs were pale 11 weeks after injury. With exclusion of other possible causes, this represents a unique case of irreversible binocular optic nerve damage and blindness secondary to radiofrequency exposure. PMID:23271888

    Mandible is the most frequently affected bone during head and neck irradiation. Late changes in the mandible may manifest in the form of reduced bone density, dental caries, loss of spongiosa trabeculations, delayed healing following dental extraction, pathologic fractures, osteoradionecrosis, trismus, growth defects in children or second malignancies. Pathologic fractures of mandibular bone are rare and may be spontaneous or traumatic (following dental extraction). We report the case of a 55-year lady, who had undergone surgery and adjuvant radiotherapy for carcinoma oral tongue T2N0M0 on a cobalt-60 unit and was disease-free. After a follow-up of 8 years post-irradiation, she presented with sudden onset oral pain and inability to open mouth. Pantomogram showed fracture at the junction of body and ramus of the mandible bilaterally. PMID:26097342

    Perinephric lymphangioma is rare disorder that may be confused with various forms of renal cystic diseases and urinomas. In this disorder a developmental malformation results in failure of developing lymphatic tissue to establish normal communication with the rest of lymphatic system. Once there is restricted drainage of lymphatic fluid the lymphatic channels dilate to form cystic masses that may be unilocular or multilocular and may be seen unilaterally or bilaterally .This condition presents with various signs and symptoms or can be just an incidental finding which in presence of misleading clinical history may be confused with other diseases. CT scan with delayed cuts and USG guided aspiration with biochemical analysis of fluid will help us in arriving to final diagnosis. PMID:20842254

    Taurodontism is a rare dental anomaly in which there is an enlarged pulp chamber at the expense of roots with apical displacement of the pulpal floor, giving it a rectangular shape. It is caused by the failure of Hertwig's epithelial root sheath to invaginate at the proper horizontal level. Taurodontism has been reported as an intraoral feature of several syndromes like Down syndrome, Klinefelter syndrome, Smith-Magenis syndrome, Hurler syndrome, etc. Association of taurodontism with hypodontia in permanent dentition has also been reported. Taurodontism in primary dentition and its association with hypodontia is very rarely reported in the literature. The present case illustrates bilateral taurodontism of primary mandibular molars with hypodontia in maxilla. PMID:23345504

    A 23-year-old woman known to have methylmalonic acidemia (MMA) since birth suffered bilateral visual loss within 5 days. Multiple sclerosis, Leber hereditary optic neuropathy, vasculitis, infections (in particular treponema), and vitamin deficiency were ruled out. The optic nerve head changed from normal in appearance to atrophic. Treatment attempts with high-dose intravenous steroids and coenzyme Q10 combined with vitamin E were ineffective. The patient's underlying disease was metabolically well controlled by strict diet and carnitine supplementation. Toxic damage of both optic nerves due to MMA is the most likely mechanism. MRI showed moderate enhancement of both optic nerves. To our knowledge, this is the first report of a morphological correlate on MRI. PMID:21873889

    Pleural tuberculosis is the first or second most common form of extrapulmonary tuberculosis as well as the main cause of pleural effusion in many countries. It is rare in young infants and is more common in children over 10 years of age. We report the case of a 19-month-old girl admitted for prolonged fever with unilateral pleural effusion. The mother reported a history of lymph node tuberculosis 6 years previously. Intravenous antibiotics with cefotaxime and vancomycin were started. Thoracocentesis yielded a serosanguinous exudate fluid with a lymphocyte predominance. The tuberculin skin test and PCR GeneXpert(©) on pleural fluid were negative. The initial outcome was favorable, but the chest X-rays 10 days after discharge showed bilateral pleural effusion. Pleural biopsy was proposed but the culture of pleural fluid was positive for Mycobacterium tuberculosis. The child was put under standard treatment for tuberculosis. The outcome was favorable.

    This case demonstrates a rarely reported bilateral scapulohumeral bony ankylosis. A young woman developed extensive heterotopic ossifications (HOs) in both shoulder joints after being mechanically ventilated for several months at the intensive care unit in a comatose status. She presented with a severe movement restriction of both shoulder joints. Surgical resection of the bony bridges was performed in 2 separate sessions with a significant improvement of shoulder function afterwards. No postoperative complications, pain, or recurrence of HOs were noted at 1-year follow-up. Mechanical ventilation, immobilization, neuromuscular blockage, and prolonged sedation are known risk factors for the development of HOs in the shoulder joints. Relatively early surgical resection of the HOs can be performed safely in contrary to earlier belief. Afterwards, nonsteroidal anti-inflammatory drugs and/or radiation therapy can be possible treatment modalities to prevent recurrence of HOs. PMID:27583120

    Summary Our patient had drainage of a large amoebic liver abscess. This got complicated by a severe degree of hypotension, which required aggressive fluid resuscitation and hydrocortisone support. Computerised tomography (CT) of the abdomen revealed bilateral adrenal gland haemorrhage (BAH) resulting in primary adrenal gland failure, which was the cause for hypotension. Patient was on long-term warfarin for provoked deep vein thrombosis of lower limb, which was discontinued before the procedure. Thrombophilia profile indicated the presence of lupus anticoagulant factor with prolonged activated partial thromboplastin time (aPTT). Patient was discharged on lifelong warfarin. This case emphasises the need for strong clinical suspicion for diagnosing BAH, rare but life-threatening condition, and its association with amoebic liver abscess and anti-phospholipid antibody syndrome (APLS). Learning points Recognition of BAH as a rare complication of sepsis.APLS can rarely cause BAH. PMID:25276353

    For more than a hundred years, it has been supposed that canine guidance should be avoided in conventional complete dentures, since it would result in denture instability. Thus, bilateral balanced articulation has been held by many authors as fundamental for treatment success. However, randomized clinical trials have shown that balanced articulation is not as important as previously thought. The issue about which occlusal concept is the most appropriate for individual needs is clinically and economically relevant for both the dentist and dental technician. Therefore, the purpose of this study is to provide an evidence-based update on complete denture occlusion. Clinical Relevance: The issue about which occlusal concept is the most appropriate for individual needs is clinically and economically relevant. PMID:25073224

    A 40-year-old male presented to our outpatient department with the chief complaint of a painless mass on his right testis with gradual size increase over the past two months. Physical examination and ultrasound revealed a firm and nontender mass both on the right and on the left testis. The only elevated biomarker was b-hcG (24,7 mIU/mL) and computer tomography (CT) did not reveal any pathology. Bilateral high orchiectomies were performed, without previous frozen storage of the sperm. Histology proved typical seminoma of the left testis and embryonal carcinoma of the right testis. He received two cycles of adjuvant combination chemotherapy with bleomycin, etoposide, and cisplatin. Six months after the operation no residual tumor or recurrence was observed. PMID:26060594

    Bilateral adrenal hemorrhage (BAH) is a rare complication typically seen in critically ill patients, which can lead to acute adrenal insufficiency and death unless it is recognized promptly and treated appropriately. We describe the case of a 64-year-old man with polycythemia vera found to be unresponsive with fever, hypotension, tachycardia, and hypoglycemia. Electrocardiogram showed ST-elevation with elevated troponin, hemoglobin, prothrombin time, and partial thromboplastin time. He required aggressive ventilator and vasopressor support. Despite primary coronary intervention, he remained hypotensive. Random cortisol level was low. He received stress dose hydrocortisone with immediate hemodynamic stability. BAH was highly suspected and was confirmed by non-contrast abdominal computed tomography. Prompt recognition and timely initiated treatment remain crucial to impact the mortality associated with acute adrenal insufficiency. PMID:27609733

    Pigmented villonodular synovitis is a disorder resulting in a villous, nodular, or villonodular proliferation of the synovium, with pigmentation related to the presence of hemosiderin. These lesions are almost exclusively benign with rare reports of malignancy. Pigmented villonodular synovitis can occur in a variety of joints and at any age but most often occurs within the knee in the young adult. Pigmented villonodular synovitis is a rare disease entity, and bilateral synchronous or metachronous involvement of a joint is even more uncommon, with few reports previously described in the literature. We present a case of pigmented villonodular synovitis involving both the right and left knee in the same patient, with radiographic imaging, magnetic resonance imaging, photograph and video intraoperative imaging, and pathologic correlation.

    Rotational vertebral artery occlusion, or bow hunter's stroke, is reversible, positional symptomatic vertebrobasilar ischemia. The typical mechanism of action is obstruction of a dominant vertebral artery with contralateral head rotation in the setting of baseline ipsilateral vertebral artery stenosis or occlusion. Here we present a rare case of mechanical occlusion of bilateral patent vertebral arteries manifesting as near syncope with rightward head rotation. Diagnostic cerebral angiography showed dynamic right C5 vertebral occlusion and left C2 vertebral occlusion. The patient underwent right C4/5 transverse process decompression. Postoperative angiogram showed patent flow through the right vertebral artery in neutral position and with head turn with resultant resolution of symptoms. PMID:23465174

    2016-06-01

    In this paper, we introduce a high efficient and practical disparity estimation using hierarchical bilateral filtering for real-time view synthesis. The proposed method is based on hierarchical stereo matching with hardware-efficient bilateral filtering. Hardware-efficient bilateral filtering is different from the exact bilateral filter. The purpose of the method is to design an edge-preserving filter that can be efficiently parallelized on hardware. The proposed hierarchical bilateral filtering based disparity estimation is essentially a coarse-to-fine use of stereo matching with bilateral filtering. It works as follows: firstly, the hierarchical image pyramid are constructed; the multi-scale algorithm then starts by applying a local stereo matching to the downsampled images at the coarsest level of the hierarchy. After the local stereo matching, the estimated disparity map is refined with the bilateral filtering. And then the refined disparity map will be adaptively upsampled to the next finer level. The upsampled disparity map used as a prior of the corresponding local stereo matching at the next level, and filtered and so on. The method we propose is essentially a combination of hierarchical stereo matching and hardware-efficient bilateral filtering. As a result, visual comparison using real-world stereoscopic video clips shows that the method gives better results than one of state-of-art methods in terms of robustness and computation time.

There were no differences in wound complications, post-operative respiratory complications, or other adverse effects in the three groups. Operating time was similar in the unilateral and bilateral simultaneous repairs (median 55 min), but was longer (100 min) for the combination of two sequential repairs. Hospital stay was shortest for patients undergoing unilateral repair (2 days) but was less with bilateral simultaneous repair (4 days) than after two sequential repairs (total of 6 days). There were 12 (11%) wound complications of which five (5%) were infections. There was no difference in complication rate between unilateral and bilateral hernia repair. Postoperative recovery was assessed prospectively and was recorded at 1 month. There was no difference between unilateral and bilateral simultaneous repairs in the number of days before the patient was able to climb stairs easily, drive a car or return to work. The duration of the requirement for analgesia was similar in each group. We conclude that bilateral simultaneous hernia repair can be carried out with no greater morbidity than a unilateral repair, and the return to normal activity is as rapid. Bilateral hernias should be repaired simultaneously rather than sequentially. PMID:2221764

    Ganglion cysts usually arise from the tissues around the facet joints. It is usually associated with degenerative cahanges in facet joints. Bilateral thoracic ganglion cysts are very rare and there is no previous case that located in bilateral intervertebral foramen compressing the L1 nerve root associated with severe radiculopathy. We report a 53 years old woman who presented with bilateral groin pain and severe numbness. Magnetic resonance imaging revealed bilateral cystic mass in the intervertebral foramen between 12th thoracal and 1st lumbar vertebrae. The cystic lesions were removed after bilateral exposure of Th12-L1 foramens. The result of hystopathology confirmed the diagnosis as ganglion cyst. The ganglion cyst may compromise lumbar dorsal ganglion when it located in the intervertebral foramen. The surgeon should keep this rare entity in their mind for differential diagnosis.

    Piriformis syndrome (PS) is an uncommon neuromuscular disorder caused by the piriformis muscle (PM) compressing the sciatic nerve (SN). The main symptom of PS is sciatica, which worsens with certain triggering conditions. Because the pathophysiology is poorly understood, there are no definite diagnostic and therapeutic choices for PS. This case report presents a young woman who mainly complained of bilateral leg weakness. Electromyography revealed bilateral sciatic neuropathy and magnetic resonance imaging confirmed structural lesions causing entrapment of the bilateral SNs. After a laborious diagnosis of bilateral PS, she underwent PM releasing surgery. Few PS cases present with bilateral symptoms and leg weakness. Therefore, in such cases, a high level of suspicion is necessary for accurate and prompt diagnosis and treatment. PMID:26798622

    Uveal melanoma is the most common primary intraocular neoplasm in adults. Its bilateral localization is extremely rare. The aim of the paper is analysis of the cases of bilateral uveal melanoma. Five bilateral uveal melanoma patients were diagnosed in the Department of Ophtalmology and Ocular Oncology beetwen 1980 and 2014. Both eyes of four patients were threated with brachytherapy. Final enulcleation of the one eye was performed in three patients. It was the primary treatment in one patient. The presence of uveal melanoma was confirmed by pathological examination in all cases after surgical removal of eyeball and in one after local resection of iris tumor. Metastatic lesions were diagnosed in lungs and liver in two patients. Three patients are still followed-up at our institution. The possibility of bilateral uveal melanoma should considered although it is extremely rare. bilateral uveal melanoma, brachytherapy, enucleation. PMID:26638545

    2016-01-01

    Bilateral clavicle fractures are uncommonly reported in the literature with the incidence being less than 0.5% of all the clavicle fractures. Bilateral clavicle fractures are caused either by high-energy transfer of compression forces across both shoulder girdles or by a direct trauma to one clavicle followed by that to the other clavicle. These fractures could be missed due to their association with more severe chest injuries or a more symptomatically displaced fracture on one side or due to inadequate chest radiographs. We report three cases of traumatic bilateral clavicle fractures with three modes of injuries in different age groups. All the fractures were treated conservatively with good functional outcomes without any sequelae. Bilateral clavicle fractures should be actively sought by every trauma team with proper clinical examination and chest radiographs including both shoulder joints in high-energy trauma cases or with bilateral shoulder compression injuries.

    Hip and pelvic pain during pregnancy or after delivery is a common problem in young females, and in most cases this problem has a self-limiting course. The patient described in this case suffered from severe hip pain after childbirth. MR imaging study was performed and it showed arthritis of bilateral hip joints and osteomyelitis of femoral heads with an abscess in the surrounding muscle. Infection, such as septic arthritis or osteomyelitis, is an extremely rare cause of peripartum joint pain. The patient's clinical symptoms and laboratory findings improved with antibiotic therapy. However, limitation of motion of the bilateral hip joints persisted although the patient continued rehabilitative therapy for 15 months, and the patient had to undergo bilateral total hip replacement. Hereby, we present a case of severe osteomyelitis and pyogenic arthritis of bilateral femoral heads and hip joints after delivery, which eventually required bilateral total hip replacement.

    Dural arteriovenous fistulae (DAVFs) are infrequent lesions, the most common locations of which are the cavernous, sigmoid and transverse sinuses. The cribiform plate is one of the less frequent sites for DAVFs, where they entail a high hemorrhage risk. Feeding arteries for ethmoidal DAVFs can be uni- or bilateral. However, the draining fistulous system has classically been described as unilateral. The authors report the second case in literature of bilateral ethmoidal DAVF, which is defined as that with bilateral draining veins. The present case was diagnosed only after surgical exploration of both cribiform plates. No preoperative radiological test could detect the presence of a bilateral venous draining system from the ethmoidal DAVF. Possible reasons for that lack of presurgical diagnosis are discussed. Bilateral surgical exploration of the anterior cranial fossa is recommended when dealing with ethmoidal DAVFs, even when they seem to be unilateral on preoperative studies. PMID:20727670

  20. Comparative gait initiation kinematics between simulated unilateral and bilateral ankle hypomobility: Does bilateral constraint improve speed performance?

    Improvement of motor performance in unilateral upper limb motor disability has been shown when utilizing inter-limb coupling strategies during physical rehabilitation. This suggests that 'default' bilateral central motor commands are facilitated. Here, we tested whether this bilateral motor control principle may be generalized to the lower limbs during gait initiation, which involves alternate bilateral actions. Disability was simulated by strapping to produce ankle hypomobility. Healthy adult subjects initiated gait at a self-paced speed with no ankle constraint (control), or with the stance, swing or bilateral ankles strapped. The duration of the anticipatory postural adjustments lengthened and the center of mass instantaneous progression velocity at foot-off decreased when the ankle was strapped. During the step execution phase, progression velocity at foot-contact was higher when both ankles were strapped compared to unilateral strapping of the stance ankle. These findings suggest that bilateral central motor commands are favored during walking tasks. Indeed, unilateral constraint of the stance ankle should compel the central nervous system to adapt specific commands to the constraint and normal sides whereas the 'default' bilateral motor commands would be utilized when both ankles are strapped leading to better kinematics performance. Bilateral in-phase upper limb coordination and bilateral alternating lower limb locomotor movements may share similar control mechanisms. PMID:26197055

    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. PMID:19894280

  2. Speckle reducing bilateral filter for cattle follicle segmentation

    PubMed Central

    2010-01-01

    Background Ultrasound imaging technology has wide applications in cattle reproduction and has been used to monitor individual follicles and determine the patterns of follicular development. However, the speckles in ultrasound images affect the post-processing, such as follicle segmentation and finally affect the measurement of the follicles. In order to reduce the effect of speckles, a bilateral filter is developed in this paper. Results We develop a new bilateral filter for speckle reduction in ultrasound images for follicle segmentation and measurement. Different from the previous bilateral filters, the proposed bilateral filter uses normalized difference in the computation of the Gaussian intensity difference. We also present the results of follicle segmentation after speckle reduction. Experimental results on both synthetic images and real ultrasound images demonstrate the effectiveness of the proposed filter. Conclusions Compared with the previous bilateral filters, the proposed bilateral filter can reduce speckles in both high-intensity regions and low intensity regions in ultrasound images. The segmentation of the follicles in the speckle reduced images by the proposed method has higher performance than the segmentation in the original ultrasound image, and the images filtered by Gaussian filter, the conventional bilateral filter respectively.

    The present short communication puts on record a case of bilateral, multiple follicular cysts in a water buffalo along with a detailed description of its ovarian biometry and follicular fluid composition. The ovarian weight and biometrical parameters were much higher than in normal cycling buffaloes. A total of three follicular cysts were observed, two on the right ovary and one on the left ovary, measuring 4.9, 3.0 and 2.6 cm yielding 21, 9 and 5 ml of follicular fluid, respectively. The cystic fluid was deep yellow in colour with a viscous consistency. The follicular fluid concentrations of glucose, total protein, cholesterol, acid phosphatase, calcium, phosphorus and progesterone in all the cysts were within the range reported previously in normal buffalo follicular fluid; however, the alkaline phosphatase concentration in cyst 1 and total bilirubin concentration in cysts 1 and 2 were higher than the values in normal follicular fluid. In contrast, the levels of urea nitrogen in cysts 1 and 3, and oestradiol in cyst 3 were lower than the normal values. All the three follicles had an oestradiol to progesterone ratio less than 1. The results of our study suggest that follicular cysts in buffalo are oestrogenically inactive and have an altered concentration of certain biochemical and hormonal constituents. PMID:21086160

    An 11-year-old intact female Doberman Pinscher was presented with the complaint of non-ambulatory tetraparesis. Clinical and neurological examination revealed a caudal cervical spinal cord disfunction (C6-T2 spinal cord segments). Magnetic resonance imaging and computed tomographic (CT) findings of the cervical spine were consistent with caudal cervical spondylomyelopathy (CSM). During the diagnostic work-up for the cervical spine, bilateral bone anomalies involving the seventh cervical vertebra and the first ribs were found on radiographs and CT examination. The rib anomalies found in this dog appear similar to cervical ribs widely described in human medicine. In people, cervical ribs are associated with a high rate of stillbirth, early childhood cancer, and can cause the thoracic outlet syndrome, characterized by neurovascular compression at level of superior aperture of the chest. In dogs, only some sporadic anatomopathological descriptions of cervical ribs exist. In this report the radiographic and CT findings of these particular vertebral and rib anomalies along with their relationships with adjacent vasculature and musculature are shown intravitam in a dog. Specific radiographic and CT findings described in this report may help in reaching a presumptive diagnosis of this anomaly. Finally, their clinical and evolutionary significance are discussed.

    Background: Since the first successful hand transplantation in 1998, there have been multiple reports about surgical technique, transplant survival, and immunosuppression. However, very limited published data exist on psychosocial outcomes following hand transplantation. Methods: We report psychosocial outcomes in a patient with bilateral hand transplants at the midforearm level with serial follow-ups over 3.5 years. Different metrics used to study psychosocial outcomes included the following: SF-12, CES-D, Dyadic Adjustment Scale, Rosenberg SE, and EQ-5D. Result: Preoperatively, our patient did not have any evidence of depression (CES-D = 3), had a nonstressful relationship with his spouse (Dyadic Adjustment Scale = 100), and self-esteem was in the normal range (Rosenberg SE = 21). These metrics and his additional scales (SF-12 MCS, EQ-5D, and EQ-VAS) did not change appreciably and were within the normal range for the entire duration of 3.5-year follow-up at all different time points. Conclusion: With the increasing popularity of hand transplantation and the increasing awareness of the importance of psychosocial parameters in overall success, appropriate, comprehensive, and standardized measurements are important. These should be an integral part of patients’ screening and follow-up. PMID:26579339

    We describe reconstructive surgeries, therapy, prostheses, and adaptations for a patient who experienced bilateral amputation of all five fingers of both hands through the proximal phalanges in January 1992. The patient made considerable progress in the use of his hands in the 10 mo after amputation, including nearly a 120% increase in the active range of flexion of metacarpophalangeal joints. In late 1992 and early 1993, the patient had "on-top plasty" surgeries, in which the index finger remnants were transferred onto the thumb stumps, performed on both hands. The increased web space and functional pinch resulting from these procedures made many tasks much easier. The patient and occupational therapists set challenging goals at all times. Moreover, the patient was actively involved in the design and fabrication of all prostheses and adaptations or he developed them himself. Although he was discharged from occupational therapy in 1997, the patient continues to actively find new solutions for prehension and grip strength 18 yr after amputation.

    Iatrogenic pneumothorax secondary to thoracentesis is relatively uncommon but does present to the emergency department (ED). Iatrogenic pneumothoraces developing tension physiology are rare. We report a case of an elderly female patient presenting to the ED with an isolated chief complaint of bilateral leg swelling, beginning the day after a thoracentesis, which was performed 3 days prior for pleural effusions secondary to lung cancer. Given that the patient was hemodynamically stable, not hypoxic, and had a history of chronic obstructive pulmonary disease and recent history of pleural effusions with diminished lung sounds throughout, this was a radiologic diagnosis. Immediately upon diagnosis, a 10F intrapleural catheter was inserted at the second intercostal space in the midclavicular line with successful resolution of the tension phenomenon. The patient tolerated the procedure well, and the catheter was removed on hospital day 2 without recurrence of the pneumothorax. She experienced resolution of her lower extremity swelling and was discharged from the hospital 2 days later. Isolated inferior vena cava syndrome secondary to a subacute tension pneumothorax was likely the cause of the patient's symptoms. This presentation is very rare and is undocumented in the literature. A high degree of suspicion for acute chest pathology should exist in every patient presenting to the ED with history of recent pleural violation. PMID:26003746

    Among alcohols, methanol intoxication is the most frequently associated with cerebral toxicity, causing retinal damage and putaminal necrosis. This consequence is believed to be due to the transformation of methanol into formic acid. We describe the case of a patient who presented with acute impairment of consciousness and tetraparesis after she had been drinking several bottles of a topical antiseptic solution (Lysoform Medical) containing 2-bromo-2-nitro-1,3-propandiol (bronopol) among excipients, in order to lose weight during previous months. Moreover, she had been on a strict slimming diet. Soon after admission, a severe respiratory and metabolic impairment became rapidly evident, requiring an intensive care unit admission. Cerebral MRI showed the presence of bilateral putaminal necrosis. She recovered in 10 days, surprisingly, without any evident clinical neurological signs. Methanol, also bronopol, when diluted in aqueous solution, at warm temperature and/or higher pH, may release formaldehyde, which is converted into formic acid, a basal ganglia toxic compound.

A plain chest film showed dilated loops of large bowel and blood results on admission showed an acute kidney injury (stage 3). A diagnosis of bowel obstruction was made initially but a CT scan of the abdomen showed bilateral obstructing calculi. After initial resuscitation, the patient had bilateral ultrasound-guided nephrostomies and haemofiltration. He later underwent bilateral antegrade ureteric stenting.

    Unilateral carotid cavernous fistula presents with ipsilateral ocular findings. Bilateral presentation is only seen in bilateral fistulas, usually associated with indirect (dural) carotid cavernous fistulas. Direct carotid cavernous fistulas are an abnormal communication between the internal carotid artery and the cavernous sinus. They typically begin with a traumatic disruption in the artery wall into the cavernous sinus, presenting with a classic triad of unilateral pulsatile exophthalmos, cranial bruit and episcleral venous engorgement. We report the case of a 38-year-old male with traumatic right carotid cavernous sinus fistula and bilateral ocular presentation successfully treated by interventional neuroradiology. PMID:26955353

    Abstract We report a 64-year-old man with diabetic chorea whom we investigated with dopamine transporter SPECT, 18F FDG PET, 99mTc ethylcysteinate dimer (ECD) SPECT, and 123I metaiodobenzylguanidine (MIBG) scintigraphy. Dopamine transporter SPECT revealed reduced 123I ioflupane binding in the bilateral striatum. 18F FDG PET showed metabolic dysfunction in the bilateral striatum, as shown in earlier studies. 99mTc ECD SPECT revealed reduced brain perfusion in the bilateral caudate nucleus and putamen. 123I MIBG scintigraphy revealed no cardiac sympathetic nerve dysfunction. Our case suggests a possible nigrostriatal presynaptic dopaminergic involvement in diabetic chorea. PMID:26975011

    Geminated teeth occur more frequently in the deciduous dentition than in the permanent dentition, with prevalence figures of 0.6% and 0.1%, respectively. Bilateral presentation is rare. A survey of the literature showed that the prevalence estimates for bilateral double teeth range from 0.01% to 0.04% in the deciduous dentition, and 0.05% in the permanent dentition. In this article, we report a rare case of bilateral fusion of the maxillary permanent incisors, discuss possible histogenetic mechanisms related to this anomaly, and explain the treatment management.

    Topographic profiles have been obtained 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 noted within domains between linear discontinuities in directions parallel to the strike of the discontinuities. The results suggest that western Aphrodite Terra is similar to terrestrial oceanic divergent plate boundary environments, and that the cross-strike discontinuities are analogous to oceanic fracture zones rather than strike-slip faults.

  18. Parkinsonism and transient bilateral ptosis in systemic lupus erythematosus

    Many neurological abnormalities have been described in systemic lupus erythematosus (SLE), but transient bilateral ptosis and parkinsonism are rarely encountered. This paper describes a young Malay girl with SLE who develops psychosis, bilateral ptosis and parkinsonism during an exacerbation of her illness. These neurological features disappeared after adequate treatment with cyclophosphamide. Though the pathogenesis of these neurological abnormalities is not clearly known, it is likely that transient bilateral ptosis is due to myoneural dysfunction not unlike that of myasthenia gravis. As for parkinsonism, it can probably be explained on the basis of ‘vasculitis’ of the basal ganglia leading to microinfarcts and encephalomalacia. ImagesFig. 1Fig. 2

    We present a case of synchronous malignant pheochromocytoma in bilateral adrenal glands. A 73- year-old man presented to our hospital with bilateral adrenal masses incidentally found during abdominal ultrasonography examination for an unrelated issue. The patient had a 30-year history of hypertension and paroxysmal atrial fibrillation. Computed tomography and magnetic resonance imaging showed heterogeneous tumors in bilateral adrenal glands and an enlarged para-aortic lymph node. Hormonal examinations revealed a high value of urinary catecholamines. Metaiodobenzylguanidine (MIBG) scintigraphy showed increased uptake in bilateral adrenal glands and the lymph node. Both adrenal tumors and the node were surgically removed. Pathological examination revealed histologically distinct tissue between the two adrenal tumors. The patient received five cycles of adjuvant chemotherapy, consisting of cyclophosphamide, vincristine, and dacarbazine. The patient has been in remission for 32 months following surgical treatment.

    A 17-year-old teen was hospitalized with bilateral pneumothorax. After the bilateral lungs were expanded using catheter tubes, he fully recovered and he was discharged from our hospital. He had a history of colon perforation. Ehlers-Danlos syndrome (EDS) was suspected due to the combination of colon perforation and pneumothorax, and EDS type IV was confirmed after a genetic study identified a c.1511g>a mutation in the COL3A1 gene. This is the first report of bilateral pneumothorax caused by EDS type IV. Clinicians should consider EDS type IV in the differential diagnosis for bilateral pneumothorax in conjunction with distinct previous histories and radiological findings. PMID:26666608

    A 4-year-old girl presented with a history of poor vision and oscillation of both eyes since infancy. Ocular examination revealed the best corrected visual acuity of 2/60 in right eye and 3/60 in left eye. Horizontal pendular nystagmus was present in both eyes. Fundus examination revealed morning glory disc anomaly (MGDA) bilaterally. Radiographic imaging of the brain revealed central nervous system anomalies. The guarded visual prognosis was explained and the patient referred for low vision rehabilitation and advised yearly follow-up. MGDA is very rarely bilateral. We aim to highlight the distinguishing features of bilateral MGDA from other excavated optic nerve head anomalies which could also present bilaterally but vary in their associations, management and prognosis.

    This report describes a case of bilateral greater occipital neuralgia treated with cooled radiofrequency ablation. The case is considered in relation to a review of greater occipital neuralgia, continuous thermal and pulsed radiofrequency ablation, and current medical literature on cooled radiofrequency ablation. In this case, a 35-year-old female with a 2.5-year history of chronic suboccipital bilateral headaches, described as constant, burning, and pulsating pain that started at the suboccipital region and radiated into her vertex. She was diagnosed with bilateral greater occipital neuralgia. She underwent cooled radiofrequency ablation of bilateral greater occipital nerves with minimal side effects and 75% pain reduction. Cooled radiofrequency ablation of the greater occipital nerve in challenging cases is an alternative to pulsed and continuous RFA to alleviate pain with less side effects and potential for long-term efficacy.

    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. PMID:22807945

    Limbal stem cell deficiency (LSCD) is now established as a distinct entity with a spectrum of clinical manifestations. Bilateral LSCD presents a unique set of challenges to the clinician dealing with ocular surface disease, due to the underlying causes, clinical presentation, and adnexal status, as well as lack of a source of autologous limbal stem cells. Various surgical modalities have been described to achieve visual rehabilitation in patients with bilateral LSCD. These can primarily be divided into cell-based therapies and implantation of keratoprostheses. In this review, the surgical options for management of bilateral LSCD, including autologous and allogeneic cell-based therapies and different types of keratoprostheses are described and classified. The indications, prerequisites, technique, results and complications of each modality are discussed. Based on the status of the ocular surface, an algorithm for choosing appropriate surgical management for vision restoration in bilateral LSCD has been proposed. PMID:27151421

    Intraoral vertical ramus osteotomy (IVRO) is an effective surgical procedure that is used for the correction of mandibular prognathism. However, application of IVRO for mandibular advancement has been limited because of the instability of the proximal segments caused by the gap between the distal and proximal segments. We report a case of unilateral mandibular advancement with bilateral IVRO for the correction of facial asymmetry. This case shows possible application of bilateral IVRO for unilateral mandibular advancement without any means of fixation. PMID:25974825

    Introduction: Bilateral shoulder dislocation are most commonly posterior type. These are most commonly due to seizure disorder and electrocution. Anterior shoulder dislocations occurring bilaterally without any predisposing factors are very rare. These types of injuries are due to trauma with a unique mechanism of injury. To best of our knowledge there are only few cases of similar kind are reported in literature. We hereby report a interesting case of posttraumatic, bilateral anterior dislocation of shoulder without associated fracture in a 45 old women without any predisposing pathoanatomy. Case report: A 45-year-old women presented to casualty with sudden onset of pain and restriction of movement in both shoulders fallowing trauma. Immediately post trauma she had severe pain and restriction of both shoulders. On examination arms were abducted and externally rotated. Bilateral shoulder movements were painful and restricted. There was loss of round contour of shoulder with increased vertical diameter of axilla anteriorly. Radiological examination revealed bilateral anterior dislocation of the shoulders without any associated fractures. Closed reduction done by Milch technique after intraraticular lignocaine injection. MRI of bilateral shoulder showed no pathological lesion. Both shoulders were immobilized with a shoulder immobilizer for three weeks. Conclusion: Most of the bilateral shoulder dislocations are posterior type seen in seizure disorders. Bilateral traumatic anterior shoulder dislocations are rare and are seen as a result of unique mechanism of injury. In our case patient had a fall on her elbows causing forced extension. If diagnosed and treated promptly completely normal function of the shoulders can be restored. PMID:27298892

    The incidence of bilateral breast reconstruction is increasing particularly due to genetic counseling and the option for bilateral prophylactic mastectomies. The decision to undergo a prophylactic mastectomy depends on the achievable outcomes of breast reconstruction. The free superior gluteal artery perforator flap (sGAP) flap is one option for autologous bilateral reconstruction which has rarely been reported.All bilateral sGAP flaps performed in the department of plastic surgery at the Behandlungszentrum Vogtareuth over a period of 4.5 years were retrospectively analyzed for indication, success rate, and complications.Thirty sGAP flaps were performed for bilateral breast reconstruction. The average age of the 15 women was 42 years and the average body mass index was 20.8. Indications for breast reconstruction were predominantly prophylactic mastectomies (60%). Indication for a sGAP flap was either a thin patient with insufficient abdominal tissue or a 2-staged bilateral reconstruction. 83% of the breast reconstructions were performed secondarily and 93% in 2 stages. The average operating time was 7 hours 12 minutes. Twenty-nine flaps (97%) were successful. Complications were fat necrosis (n = 3), hematoma (n = 3), and breast seroma (n = 1). Donor site complications were seroma (n = 8), infection (n = 1), and wound dehiscence (n = 1).Our results with bilateral breast reconstruction with the sGAP flap show cosmetically appealing results with high success and low complication rates on the breast. However, seromas on the donor site occurred in 27%. In addition, the sGAP flap is a technically demanding and time consuming operation. We recommend the sGAP flap when the abdomen has not enough tissue bulk to perform a deep inferior epigastric perforator flap or for a 2-staged bilateral reconstruction. This is often the case in women with a hereditary high risk of breast cancer who often present as young and slim patients. PMID:20010408

    Benefits of bilateral practice both for the non-dominant and for the dominant body side have been shown in several studies. Thereby, most of the studies included movement tasks of the upper extremity or investigated sports games in which the ability of acting bilaterally is an essential basis for success and, thus, a bilateral practice is reasonable anyway. Individual unilaterally performed sports including movement tasks of the lower extremity are rarely investigated. Therefore, the aim of our study was to test if contralateral transfer due to bilateral practice can be found in an unilaterally performed sport including the lower extremity. We trained and tested 61 adolescent athletes in long jump to compare the jumping performance of the dominant leg after a 12-week practice period between two groups: a bilateral practice group that practiced specific long jump exercises with both the dominant and non-dominant leg and an unilateral practice group that practiced specific long jump exercises only with the dominant leg. Results showed a superior effect of bilateral practice compared to unilateral practice regarding the jumping performance of the dominant leg. The performance increase at post-test and retention-test for the dominant limb was significantly higher for the bilateral practice group (pre-to-post: 5.2%, pre-to-retention: 7.4%) compared to the unilateral practice group (pre-to-post: 3.4%, pre-to-retention: 4.5%). Thus, bilateral practice should be established in the early practice programmes of track and field athletes to improve the performance of the dominant take-off leg. PMID:26864045

    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. PMID:25606034

    Osteochondritis dissecans (OCD) of the lateral femoral condyle sometimes occurs with a discoid lateral meniscus. Recently, it was reported that OCD of the lateral femoral condyle occurred after total removal of the lateral meniscus. We report the case of a 12-year-old boy with bilateral OCD of the lateral femoral condyle following bilateral total removal for discoid lateral meniscus. Valgus deviation of the knee after total removal and increased sporting activity might have concentrated excessive stress on the lateral condyles in the standing position. As a result, bilateral OCD might have occurred. Drilling of the areas of OCD on the bilateral lateral femoral condyles was done and the patient wore inner wedge arch supports postoperatively. After 2 years, neither knee pain nor arthrosis has occurred so far, but long-term follow-up of this patient is considered to be necessary. PMID:17985146

  20. EphA4-Mediated Ipsilateral Corticospinal Tract Misprojections Are Necessary for Bilateral Voluntary Movements But Not Bilateral Stereotypic Locomotion

    In this study, we took advantage of the reported role of EphA4 in determining the contralateral spinal projection of the corticospinal tract (CST) to investigate the effects of ipsilateral misprojections on voluntary movements and stereotypic locomotion. Null EphA4 mutations produce robust ipsilateral CST misprojections, resulting in bilateral corticospinal tracts. We hypothesize that a unilateral voluntary limb movement, not a stereotypic locomotor movement, will become a bilateral movement in EphA4 knock-out mice with a bilateral CST. However, in EphA4 full knock-outs, spinal interneurons also develop bilateral misprojections. Aberrant bilateral spinal circuits could thus transform unilateral corticospinal control signals into bilateral movements. We therefore studied mice with conditional forebrain deletion of the EphA4 gene under control by Emx1, a gene expressed in the forebrain that affects the developing CST but spares brainstem motor pathways and spinal motor circuits. We examined two conditional knock-outs targeting forebrain EphA4 during performance of stereotypic locomotion and voluntary movement: adaptive locomotion over obstacles and exploratory reaching. We found that the conditional knock-outs used alternate stepping, not hopping, during overground locomotion, suggesting normal central pattern generator function and supporting our hypothesis of minimal CST involvement in the moment-to-moment control of stereotypic locomotion. In contrast, the conditional knock-outs showed bilateral voluntary movements under conditions when single limb movements are normally produced and, as a basis for this aberrant control, developed a bilateral motor map in motor cortex that is driven by the aberrant ipsilateral CST misprojections. Therefore, a specific change in CST connectivity is associated with and explains a change in voluntary movement. PMID:24719100

    Introduction Bilateral femoral neck fractures without major trauma are rare and related to several conditions. Insufficiency fractures due to the use of anti-epileptic drug are one of the rare causes. This case study is about bilateral femoral neck insufficiency fractures resulting from chronic use of anti-epileptic drug. Presentation of case A 26-year-old woman was referred to our emergency department with a complaint of bilateral groin pain and a 12-year history of irregular carbamazepine use. The diagnosis was bilateral femoral neck insufficiency fractures due to irregular long-term carbamazepine use. One-stage bilateral dynamic hip screw osteosynthesis was performed. After 2 years of follow up, good result was obtained. Discussion There are several risk factors for insufficiency fracture, and antiepileptic drug related osteoporosis is one of the reason. These drugs have negative effect on bone methabolism and bone mineral density. Conclusion To our knowledge, this is the first case in the literature of bilateral femoral neck insufficiency fracture due to chronic carbamazepine use. Joint and bone pain with a history of long-term use of anti-epileptic drug should be investigated carefully, and insufficiency fractures should be kept in mind. PMID:25528039

    Congenital bilateral perisylvian syndrome (CBPS) is a type of cortical developmental abnormality associated with distinctive clinical and imaging features. Clinical spectrum of this syndrome is quite heterogeneous, with different degrees of neurological impairment in affected individuals. High-definition magnetic resonance imaging (MRI) has a great importance in revealing the presence of CBPS, but is limited in elucidating the heterogeneous clinical spectrum. The arcuate fasciculus (AF) is a prominent language tract in the perisylvian region interconnecting Broca and Wernicke areas, and has a high probability of being affected developmentally in CBPS. Herein, we report a case of CBPS with investigation of AF using diffusion tensor imaging (DTI) and fiber tractography in relation to clinical findings. We postulated that proven absence of AF on DTI and fiber tractography would correlate with a severe phenotype of CBPS. PMID:24852949

    BACKGROUND This retrospective clinical investigation aimed to evaluate the short-term effectiveness and safety of SBCAS for symptomatic bilateral high-grade CS. MATERIAL AND METHODS From 2009 to 2014, 145 patients were recruited. Among them, 70 underwent SBCAS, and other 75 patients underwent SAMM and served as controls. The immediate postprocedural complications and postprocedural neurological evaluation, as well as restenosis at 6-month and 1-year follow-ups in the SBCAS group are reported. Additionally, baseline risk factors for ischemic stroke, adverse effects of drugs, and outcomes at 30-day, 6-month, and 1-year follow-ups were compared between the 2 groups. RESULTS Our data did not reveal significant differences between the 2 groups in baseline risk factors for ischemic stroke. In the SBCAS group, both HPS (5.7%) and HD (40%) occurred, but they were not very severe, and no patients had postprocedural neurological deficit. Moreover, restenosis only occurred in 3 patients at 3 stent placement sites (4.3%) at 1-year follow-up. Adverse effects of drugs did not occur in SBCAS group, but adverse effects of Bayer aspirin and Lipitor occurred in 4 patients (5.4%) and 18 patients (24.3%), respectively, at 6-month follow-up in the control group. Furthermore, there were significant differences in outcomes between the 2 groups at 30-day, 6-month, and 1-year follow-ups, in that NIHSS, CS ratio, and incidence of endpoint events, as well as 1-year cumulative probability of endpoint events, were all lower in the SBCAS group than in the control group (p<0.05). CONCLUSIONS Compared to SAMM, we found that SBCAS was more effective and safer for symptomatic bilateral high-grade CS. PMID:27542158

Age at presentation was less in patients with pheochromocytoma (33 years) and tuberculosis (41 years) compared with PAL (48 years) and metastases (61 years) (P<0.001). The presenting symptoms for pheochromocytoma were hyperadrenergic spells (54%) and abdominal pain (29%), whereas tuberculosis presented with adrenal insufficiency (AI) (95%). The presenting symptoms for PAL were AI (57%) and abdominal pain (43%), whereas all cases of metastasis had abdominal pain. Mean size of adrenal masses was the largest in lymphoma (5.5cm) followed by pheochromocytoma (4.8cm), metastasis (4cm) and tuberculosis (2.1cm) (P<0.001). Biochemically, most patients with pheochromocytoma (92.8%) had catecholamine excess. Hypocortisolism was common in tuberculosis (100%) and PAL (71.4%) and absent with metastases (P<0.001). Conclusion In evaluation of bilateral adrenal masses, age at presentation, presenting symptoms, lesion size, and biochemical features are helpful in delineating varied underlying aetiologies.

    Purpose: This retrospective study examined the feasibility and efficacy of bilateral lung radiofrequency ablation (RFA) performed in a single session. Methods: From 2002-2009, patients with bilateral lung metastases were treated by RFA, where possible in a single session under general anesthesia with CT guidance. The second lung was punctured only if no complications occurred after treatment of the first lung. Five lung metastases maximum per patient were treated by RFA and prospectively followed. The primary endpoint was the evaluation of acute and delayed complications. Secondary endpoints were calculation of hospitalization duration, local efficacy, median survival, and median time to tumor progression. Local efficacy was evaluated on CT or positron emission tomography (PET) CT. Results: Sixty-seven patients were treated for bilateral lung metastases with RFA (mean age, 62 years). Single-session treatment was not possible in 40 due to severe pneumothoraces (n = 24), bilateral pleural contact (n = 14), and operational exclusions (n = 2). Twenty-seven (41%) received single-session RFA of lesions in both lungs for 66 metastases overall. Fourteen unilateral and four bilateral pneumothoraces occurred (18 overall, 66.7%). Unilateral (n = 13) and bilateral (n = 2) chest tube drainage was required. Median hospitalization was 3 (range, 2-8) days. Median survival was 26 months (95% confidence interval (CI), 19-33). Four recurrences on RFA sites were observed (4 patients). Median time to tumor progression was 9.5 months (95% CI, 4.2-23.5). Conclusions: Although performing single-session bilateral lung RFA is not always possible due to pneumothoraces after RFA of first lung, when it is performed, this technique is safe and effective.

    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.

    It still needs to be verified whether multiple syncronous homolateral and bilateral breast cancers represent intramammary spread of a single tumor or two or more separate neoplastic events. To clarify this problem, we studied the biopathological profile of 46 homolateral and 20 bilateral cases. The cancers were always surgically removed and processed at the same time. The expression of estrogen receptors (ER), progesterone receptors (PR), MIB 1, p53, and c-erbB-2 was determined. Computer-assisted image analysis (CAS 200) was used to evaluate ER, PR, MIB 1, and p53. The histological concordance was 95.6% in homolateral and 50% in bilateral cases. The immunophenotype profile of multiple homolateral neoplasms showed a concordance between 93.47% for ER and 78.26% for p53. The results were statistically significant for all parameters except for p53. In bilateral cancers, there was a significant statistical concordance for ER. These data strongly suggest that both mechanisms may exert an influence and, in particular, that in the majority of homolateral carcinomas, there may be intramammary spread of tumor cells. In multiple bilateral tumors, however, the great diversity of the histological aspects and the differences in the immunophenotype pattern suggest that the vast majority of these may constitute independent multiple events.

    A persistent trigeminal artery (PTA) is the most common anastomosis between the carotid and vertebrobasilar system. A PTA variant (PTAV) is a rare anomaly in which the cerebellar artery arises from the internal carotid artery (ICA) without connection with the basilar artery (BA). I present what I believe is the first report of bilateral PTAVs diagnosed using magnetic resonance (MR) angiography and briefly discuss the embryology of this rare anomaly. An 81-year-old woman with small infarctions underwent cerebral MR imaging and MR angiography with a 1.5-tesla imager for the evaluation of brain lesions. An MR angiography was obtained using the standard noncontrast three-dimensional time-of-flight technique. The MR angiographic demonstration of bilateral anterior inferior cerebellar arteries arising from the precavernous segment of the ICA without anastomosis to the BA indicated bilateral PTAVs. This is the first report of bilateral PTAVs diagnosed by MR angiography. The literature review indicates that an estimated prevalence of bilateral PTAVs is about 0.0012%. PMID:21544587

    Purpose The aim of the study was to investigate and analyze bilateral incidence and morphology of complete discoid lateral meniscus (DLM) with possible relation to tears and symptoms in knee joints. Materials and Methods Thirty-eight consecutive patients with symptomatic or already-torn complete DLM on magnetic resonance imaging in a unilateral knee underwent diagnostic arthroscopy on both knee joints upon agreement. The presence and shape of complete DLM as well as presence and pattern of tear were recorded accordingly. Results In total, 89.5% (34 of 38 patients) showed bilateral complete DLM, and 84.2% yielded bilateralism with identical shape. Cape-slab was the most frequent shape, comprising 68.8% of patients with identically-shaped bilateral DLM overall. Tear patterns were more frequent, in the order of longitudinal, simple horizontal, radial, and degenerative; however, the morphological shape of complete DLM was not significantly related to tear incidence or pattern. Meniscus tears and knee symptoms occurred in the contralateral knee with incidences of 32.4% and 26.5% in patients with bilateral complete DLM, respectively. Conclusion Based on these findings, more aggressive warning on the presence of discoid pathology and the need for evaluation on the contralateral knee should be considered during consultation with patients with symptomatic complete DLM in a unilateral knee in the outpatient clinic.

    OBJECTIVE: The authors confirm the advantages of simultaneous repair of bilateral inguinal hernias, indicate that it is feasible to perform the procedure under local anesthesia, and suggest that when an open tension-free technique is used, the results are superior to those of laparoscopic repair of bilateral inguinal hernias. SUMMARY BACKGROUND DATA: Between 1971 and 1995, simultaneous repair of bilateral inguinal hernias were performed in 2953 men. Initially, between 1971 and 1984, patients with indirect hernias underwent the traditional tissue approximation repair. Those with direct hernias had the same procedure, with the repair additionally buttressed by a sheet of Marlex mesh (Davol, Inc., Cronston, RI). Between 1984 and 1995, both direct and indirect hernias were repaired using the open tension-free hernioplasty procedure. METHOD: The 2953 patients underwent simultaneous repair of bilateral inguinal hernias under local anesthesia in a private practice setting in general hospitals. RESULTS: In those cases in which the "tension free" technique was used, patients experienced minimal to mild postoperative pain and had a short recovery period, with a recurrence rate of 0.1%. CONCLUSIONS: Uncomplicated bilateral inguinal hernias in adults are best treated simultaneously. It is feasible to perform the operation under local anesthesia, and when an open tension-free repair is used, postoperative pain and recovery periods are equally comparable with those of laparoscopic repair, although the complication and the recurrence rates are significantly less.

    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. PMID:15575957

    Introduction: Anterior dislocation of shoulder is commonest dislocation one encounters in day to day Orthopaedic practice. But bilateral shoulder dislocations are relatively uncommon frequently posterior and secondary to violent muscle contraction. Simultaneous bilateral anterior dislocations of shoulder following trauma is rare occurrence. Case Report: 35 year old male presented to emergency department with history fall by tripping on a stone (fall on outstretched hand). He complained of pain and difficulty in moving both the shoulders. On clinical examination, patient's both upper limbs were abducted and externally rotated. Bilaterally shoulder contour was lost with flattening. Other classical signs of shoulder dislocation viz, Bryants test, Callway sign, Hamilton's ruler test were positive. Diagnosis was confirmed on X rays. Both shoulders were reduced in emergency operation theater under general anaesthesia by Kocher's method and were immobilised in sling. Conclusion: Though bilateral shoulder dislocations are commonly posterior, usually either secondary to convulsions or electric shock, anterior dislocation has to be kept in mind , especially in post traumatic injuries. This bilateral dislocation also presents with practical problems immobilization and day to day care of patients. PMID:27298905

    To report on the outcomes of sequential bilateral cochlear implantation (CI) in children with inner ear malformation. The study design is a retrospective case study. The setting is a tertiary reference center. Two children presenting a profound bilateral congenital hearing loss with bilateral hypoplasia of the cochleovestibular nerves and hypoplasic external semicircular canal had a cochlear implant at respectively 16 months and 33 months. A second implant was proposed at respectively 17 and 20 months after the first implant. The main outcome measures are audiometry, perceptive results in closed and open set words (CSW and OSW) and oral production at follow-up. The first cochlear implant gave respectively mean thresholds at 60 dB and 70 dB. Bilateral CI showed mean threshold at respectively 40 dB and 55 dB. In case 1, perceptive assessment was 83% and 70% in respectively CSW and OSW with oral production and comprehension of sentences after 1 year follow-up. In case 2, the perceptive assessment showed no perceptive or linguistic evolution at 6 months follow-up. In cochleovestibular nerve hypoplasia, bilateral implantation could be discussed in cases of limited result after unilateral implant. PMID:19665238

    A seven-year-old, 41 kg, intact, cross breed dog, was presented with a history of bilateral hind limb lameness after falling from a height of 1 m. Clinical and radiographic findings were consistent with bilateral patellar tendon rupture. Surgical repair was performed bilaterally. The tendons were sutured primarily, and an internal splint of nylon leader was added. Good apposition of the severed tendon ends had been achieved intraoperatively; however, post operative radiographs showed supra-trochlear displacement of both patellae. The casts used to immobilize the stifle joints slipped distally and three days post operatively the tendon repair had broken down, bilaterally. Revision surgery was undertaken and the tendons were re-sutured. Nylon leader was placed through holes that had been drilled in the patellae and tibiae. The stifle joints were immobilized with type I external skeletal fixators (ESFs). Both freeform polymethylmethacrylate (PMMA) connecting bars were found to be broken at the level of the stifle joints two days later, without any disruption of the primary tendon repair. Each connecting bar was replaced with two connecting bars of PMMA reinforced with 3 mm steel wire. The dog was fully weight-bearing with a reduced range of motion in flexion immediately after removal of the ESFs at six weeks and was still sound 18 months post-operatively. Primary tendon repair in combination with adequate immobilization allowed for an excellent outcome in a complicated bilateral pathology. PMID:18545725

    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. PMID:25871299

    Bilateral simultaneous otologic surgery is being performed more commonly among otologists. The benefits of performing bilateral simultaneous cochlear implants in the pediatric population, in particular, have become increasingly recognized as the safety and efficacy of this operation have been recognized in the literature. Here we present a streamlined method of performing bilateral simultaneous otologic surgery that emphasizes midline placement of facial nerve electrodes and a method of sterile preparation and draping that affords direct exposure to both ears at one time, without the need to turn the head or adjust the drapes multiple times throughout the operation. Our approach facilitates frequent and efficient alternation between ears throughout the operation, optimizing efficiency of motion and instrumentation for the surgeon, and reducing overall operative and general anesthesia time for the patient.

    Ruiz Monroy, José Joaquín; Kita, Hiroyuki; Tanaka, Eiichi; Hasegawa, Jun

    This paper proposes an algorithm to simulate the transactions that take place in a free market of electricity. The algorithm presented is used for Bilateral Transaction Matrix (BTM) creation assuming that a day ahead load forecast is previously known. Bids can be made by both the generation side and the demand side to determine transaction prices, then the algorithm allocates the transactions according to market rules until the demand is satisfied. This creates feasible BTMs that can be used to study system security and to find future methods to regulate bilateral transactions through market mechanisms like the application of penalties to the transactions that affect the system’s security. Results show that the proposed algorithm is a good option for electricity market analysis. The proposed algorithm provides system planners with a practical tool for data creation to further study the effects of bilateral transactions in a deregulated electricity market.

    Bronchiectasis is a major cause of morbidity and mortality in developing countries. Staged bilateral segmental resection of the lungs is performed in selected patients. Our experience of surgical removal of 87 bilateral bronchiectases in 29 patients during an 11-year period was reviewed retrospectively. High-resolution computed tomography was performed preoperatively in all patients to locate the anatomic sites of bronchiectasis. The mortality and morbidity of the surgical procedure, clinical symptoms, age distribution, etiology, bacteriology, and operative procedures were analyzed. There were 22 males (76%) and 7 females (24%), aged 5 to 60 years, with a mean age of 30 years. Complications developed in 11 patients (38%); atelectasia was the most common (14%). There was one hospital death. Clinical symptoms disappeared in 19 (66%) patients, improved in 5 (17%), and were unchanged in 4 (14%). Staged bilateral resection for bronchiectases can be performed at any age with acceptable morbidity and mortality. PMID:16714699

    We report an unusual case of bilateral inflammatory aural polyps in a patient with Samter's triad. This 52-year-old patient had a history of chronic rhinosinusitis with sinonasal polyps, asthma, and aspirin sensitivity, with progressive right-sided hearing loss, otorrhea, and aural fullness. She was found to have bilateral aural polyps, with the larger obstructing lesion on the right. A computed tomography supported these findings and revealed bilateral opacification of the middle ear cleft and mastoid air cells. An initial right tympanomastoidectomy was performed with the specimen histologically resembling a typical sinonasal polyp. We speculate that this patient's middle ear polyposis is secondary to the inflammatory changes of Samter's triad. This has not been described previously in the literature. PMID:20182629

    The effects of saccadic bilateral (horizontal) eye movements on memory for a visual event narrative were investigated. In the study phase, participants were exposed to a set of pictures accompanied by a verbal commentary describing the events depicted in the pictures. Next, the participants were asked either misleading or control questions about the depicted event and were then asked to engage in 30s of bilateral vs. vertical vs. no eye movements. Finally, recognition memory was tested using the remember-know procedure. It was found that bilateral eye movements increased true memory for the event, increased recollection, and decreased the magnitude of the misinformation effect. The findings are discussed in terms of source monitoring, dual-process theories of memory and the potential neural foundations of such effects. PMID:18635303

    Introduction: Cement pressurisation is important for the insertion of both the acetabular and femoral components during Total Hip Arthroplasty (THA). Secondary to pressurization the rare phenomenon of unilateral cement incursion into the nutrient foramen has previously been reported. No bilateral case has been reported to date. This has implications both for misdiagnosis of periprosthetic fractures and for medico-legal consequences due to a presumed adverse intra-operative event. Case Report: We present a case report of a 59 year old, caucasian female who underwent staged bilateral cemented Stanmore THA. The post-operative radiographs demonstrate evidence of bilateral nutrient foramen penetration intra-operatively by standard viscosity cement. The patient suffered no adverse consequences. Conclusions: In summary, cement extravasation into the nutrient foramen is an important differential to be considered in presence of posterior-medial cement in the diaphysis of femur following THA. This requires no further intervention and has no effect on the outcome.

    Spontaneous pneumothoraces are relatively common; however, simultaneous bilateral spontaneous pneumothoraces (SBSP) have rarely been reported. This case report describes the presentation of SBSP in a 60-year-old man with occupational asthma. He was initially started on treatment for life-threatening asthma, but an early deterioration in symptoms prompted an urgent chest radiography that established the diagnosis of bilateral pneumothoraces. This was managed with bilateral needle thoracocentesis followed by stabilisation with intercostal chest drains. He was subsequently referred to the thoracic unit for minithoracotomy, bullectomy and talc pleurodesis. This case highlights the potential difficulties in diagnosing SBSP and advocates the necessity for prompt chest radiography when managing such presentations in the acute setting. PMID:24000212

    Bilateral flower symmetry has evolved multiple times during flowering plant diversification, is associated with specialized pollination, and is hypothesized to have contributed to flowering plant species richness. The genes and genetic interactions that control bilateral symmetry are well understood in the model species Snapdragon (Antirrhinum majus). I review recent insights into the genetic control of symmetry in Snapdragon. I summarize how this foundational genetic work has been integrated with mathematical modeling approaches, which together provided new insights into the control of quantitative aspects of petal shape. Lastly, I review how evolutionary studies, stemming from knowledge of the genetic control of symmetry in Snapdragon flowers, have revealed extensive parallel recruitment of a similar genetic program during repeated evolution of bilateral symmetry.

    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.

    BACKGROUND Olfactory neuroblastoma (ONB), also known as esthesioneuroblastoma, is a rare malignant head and neck cancer thought to originate from the olfactory epithelium. It typically invades contiguous structures at presentation. We report a very rare case of multifocal and ectopic ONB. CASE REPORT A 41-year-old man presented with left nasal obstruction and occasional left epistaxis associated with headache. Endoscopic examination of the nasal cavities and computed tomography suggested bilateral polypoid masses. Histopathological diagnosis after endoscopic resection established bilateral olfactory neuroblastoma of the ethmoid sinuses. The patient received postoperative radiotherapy. He remains free of disease 4 years after treatment. CONCLUSIONS To the best of our knowledge this is the second documented case of multifocal ectopic olfactory neuroblastoma. Clinicians should consider ONB in the differential diagnosis of bilateral synchronous nasal and paranasal masses to avoid delayed diagnosis. Endoscopic resection of ONB could be an option in selected cases. PMID:27097989

    Multiple symmetric lipomatosis (MSL), or Madelung's disease, is a rare disease of unknown etiology. It is characterized by the presence of loose adipose tissue deposits localized in the cervical region and upper body. MSL presenting as bilateral huge gynecomastia is an extremely rare phenomenon. The present report describes a case of MSL in a 66-year-old man. The patients presented with bilateral breast bulging. He had a history of cigarette and alcohol use. His condition was treated with a bilateral nipple-sparing mastectomy. MSL can present as a form of gynecomastia, for its accurate diagnosis and proper treatment of MSL, increasing awareness of the clinical characteristics of the disease is required, especially amongst breast surgeons. Herein, we review the literature and discuss the clinical characteristics, pathology, and surgical treatment of MSL. PMID:25548590

    Simultaneous bilateral rupture of the patellar tendon (PT) is extremely rare and is generally associated to some chronic diseases. When the rupture becomes chronic, it is more difficult to repair that as it remained untreated. The diagnosis, which is clinical, is often delayed, guided by standard radiography and confirmed by ultrasound or MRI. The management of a bilateral neglected, chronic patellar tendon rupture must address some serious difficulties: the proximally retracted patella, the reconstruction of the patellar tendon, finally, the temporary protection of this repair. We report a case of neglected bilateral rupture of the patellar tendon in a chronic hemodialysis patient, treated with a plastic surgery of the ipsilateral quadriceps tendon. PMID:26566349

    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. PMID:25871299

  12. Bilateral Foot Pain in a Collegiate Distance Runner

    1996-01-01

    A 19-year-old, white female, college freshman cross-country runner presented to the athletic training center complaining of bilateral plantar foot pain 1 week into the cross-country season. She had been treated for bilateral plantar fasciitis twice in the previous 3 years, and initial evaluation suggested a recurrence. A failure to respond to treatment led us to suspect other causes. Subsequent diagnostic imaging (bone scan, CT scan) revealed bilateral navicular stress fractures. Navicular stress fractures are probably more common than once believed. This case study describes the course of evaluation and treatment in relation to the common presentation, etiology, problems of diagnosis, and treatment of navicular stress fractures.

    Intravitreal injection is one of the most common in-office procedures performed in ophthalmic practices. In teaching institutions such as the Veterans Affairs (VA) Hospitals, patient care is delivered by physicians-in-training, while mastering intravitreal injection technique. Infectious endophthalmitis and visual loss are the most feared complications of intravitreal injections, especially in the context of recent outbreaks caused by contaminated compounded medications. Ophthalmologists and ophthalmic educators increasingly face the dilemma of timing as well as balancing the risks and benefits of bilateral treatments required by many patients. In this editorial, we discuss published reports of bilateral injections, summarize our experience with bilateral intravitreal injections in a teaching setting at the Miami VA Hospital and list our recommendations for minimizing the risk of infectious endophthalmitis.

    Purpose: To describe a clinical case and literature review of Whipple disease. Methods: A 65-year-old male with bilateral decreased visual acuity for 3 weeks as well as bilateral hypoacusia, vertigo, disequilibrium, headache and decreased strength in the right upper limb for 4 months. The clinical work-up revealed a bilateral panuveitis and an ischemic cerebellar stroke. Result: The diagnosis of Whipple disease was confirmed by histopathological analysis of adenopathy. The patient was treated with cortico-antibiotic therapy with significant clinical improvement. Conclusion: Although rare, Whipple disease is potentially fatal if left untreated, it must be always be taken into consideration before any panuveitis of an unknown cause, even in the absence of gastrointestinal symptoms.

    Pseudoangiomatous stromal hyperplasia (PASH) is a benign breast lesion commonly encountered as an incidental microscopic finding. However, it can also manifest as a mass-forming lesion (tumorous PASH) capable of recurrence after surgical excision. Most of the previously reported cases of tumorous PASH present as a single dominant mass. Here we reported a rare case of diffuse tumorous PASH involving bilateral breasts clinically mimicking malignancy. A 29-year-old African-American female presented with a one-year history of bilateral breast enlargement and asymmetry. Physical examination revealed multiple palpable nodules in bilateral breasts. Imaging studies demonstrated innumerable homogeneously enhancing masses throughout both breasts, greater on the left, with multiple cysts and edema. Biopsy of the breast nodules demonstrated histopathological changes consistent with PASH. Due to the extent of the lesions and progressive clinical symptoms, decision was made to perform bilateral mastectomy. Macroscopic examination of the bilateral mastectomy specimens revealed markedly enlarged breasts with marked edema and numerous well-defined firm nodules. Microscopic evaluation of the nodules confirmed the diagnosis of PASH. No evidence of malignancy was identified. Recognition of this rare form of PASH is essential for the proper clinical management.

    2009-06-01

    The coracoclavicular joint (CCJ) is a rare anomalous joint. Symptomatic CCJ, being an exceptional rarity, makes it difficult to formulate a standard set of practice or guidelines. We report a 50-year-old Indian man, a machine operator by profession, who experienced bilateral shoulder pain and arm paraesthesia for two years, and was diagnosed with bilateral CCJ. The symptoms gradually increased, affecting his daily activities. Dynamic magnetic resonance imaging revealed the compression of the brachial plexus in extreme shoulder abduction. After a thorough search of the literature, we retrieved four similar cases, all of them treated with individualised protocols. None of the cases was bilateral. The lack of clear evidence in any particular direction and the patient's medical condition prompted us to give a conservative trial, before embarking on more invasive methods. He showed rapid response to the conservative treatment with remission of all symptoms. To the best of our knowledge, this is the first reported case of bilateral symptomatic CCJ with bilateral thoracic outlet syndrome, that was managed conservatively. PMID:19551300

    Background: For reconstructing moderate-to-high projection breasts in nulliparous patients with insufficient abdominal tissue or prior abdominal surgeries, a unilateral inferior gluteal artery perforator (IGAP) flap is an alternative procedure. In patients with slim hips, however, unilateral gluteal tissue is insufficient and inferior gluteal crease displacement may develop postoperatively. Donor-site asymmetry is also a major disadvantage. In these circumstances, bilateral IGAP flaps provide sufficient tissue without significant gluteal deformity. Methods: We retrospectively reviewed 20 patients who underwent unilateral breast reconstruction using bilateral IGAP flaps by a single surgeon between November 2007 and December 2012. A quantitative outcome assessment was performed and compared with that of 22 unilateral IGAP flap patients operated on by the same surgeon. Results: Twenty patients underwent reconstruction with 40 IGAP flaps. Of the 40 flaps, 39 survived and 1 developed total necrosis due to repeated venous thrombosis. In 15 of 20 patients, the size of reconstructed breast was comparable to that of the contralateral breast. Final inset flap weight was 462.3 g for bilateral flaps and 244.3 g for unilateral flaps. Total operating time was 671.1 minutes (bilateral flaps) and 486.8 minutes (unilateral flaps). Conclusions: Use of bilateral IGAP flaps for breast reconstruction helps to avoid asymmetry of the inferior buttock volume and shape. Bilateral flaps provide sufficient tissue volume and allow for reconstruction of a breast comparable to the unaffected side. In patients with moderate-to-high projection breast whose abdominal tissue cannot be used for reconstruction, IGAP flaps may be a suitable alternative. PMID:25878925

    Bilateral hip dislocation is a rare condition. We report a case of traumatic bilateral hip dislocation and unilateral sciatic nerve palsy in a young woman with known idiopathic scoliosis. With prompt reduction of the dislocated hips, there was reasonable neurological recovery. There was no avascular necrosis of the femoral head or post-traumatic arthritis up to 3-year follow-up. The gender difference in incidence, as well as the predisposition of hip dislocation in scoliosis is discussed. In our case, the decreased femoral anteversion was the culprit. PMID:25809426

    A bilateral S-shaped kidney is a rare anomaly in which both the kidneys are in their normal position, in contrast to the commonly reported S-shaped fusion anomaly, in which the contralateral kidney crosses the midline to fuse with opposite kidney leaving the ipsilateral renal fossa empty. Here we present the diagnosis and management of a case of bilateral S-shaped renal anomaly with associated left pelviureteric junction obstruction and nonfunctioning kidney and right renal stones. Left kidney was managed by open nephrectomy and right kidney by PNL. PMID:26166977

    We report the case of a 13-year-old boy who had a bilateral macular injury after playing with a green laser pointer for a duration of 1 minute. Clinical examination revealed a decrease in visual acuity and macular injury in both eyes, and imaging investigations revealed a bilateral macular lesion due to exposure to the laser pointer. At 3 months' follow up, visual function had improved but remained partially impaired. This case emphasizes the importance of cautious and appropriate use of laser pointer devices because of the potential vision-threatening hazards induced by mishandling of these devices.

    Round ligament varicosity (RLV) is rare and almost all cases are pregnant women. RLV appears as a unilateral or bilateral groin swelling. Pain and tenderness may present. Clinical evaluation is inadequate for exact diagnosis because inguinal hernia has similar findings. Ultrasonography (US) is essential when a groin swelling is detected in a pregnant woman. We present gray scale US and colour Doppler US findings of a 32-week pregnant woman with bilateral RLVs at the inguinal canal, parauterine area and in the myometrium. PMID:26430450

    We report on a 15-year-old girl with bilateral scaphotrapezium-trapezoid coalitions and bipartite scaphoids. There was no history of trauma or any other associated pathology. Wrist pain was alleviated by arthrodesis of the pseudarthrosis of the scaphoid component of the coalitions. Coalition of the distal portions of the scaphoids may have interfered with union of 2 ossification centers of the scaphoid. It is also possible that the carpal coalitions predisposed the scaphoid to fracture and that this represents bilateral nonunion. PMID:23932812

    2012-01-01

    Elbow dislocation is second in frequency, after the shoulder, whereas bilateral dislocation is uncommon, even less than dislocations with concurrent associated fractures. One of the least frequent associations is the Essex-Lopresti injury which consists of a fracture of the radial head affecting the distal radioulnar joint with injury to the interosseous membrane. This is a case of bilateral elbow dislocation, one of the elbows associated with the Essex-Lopresti injury. During treatment, the premature closed reduction prevails, previously making sure the elbow is stable, the premise which will determine the orthopedic or surgical treatment of the injury.

Cases with bilateral cystic lymphangiomas of the ovary are reported very rarely in literature. We report a rare case of bilateral cystic lymphangioma of ovary associated with chylous ascites in a 35-year-old lady who presented with complaints of severe dysmenorrhoea and oligomenorrhoea since 6 months with history of chyluria for the past 3 years.

    Bloody otorrhagia in the perioperative period is an uncommon event. We present a case of bilateral bloody otorrhagia after uncomplicated robotic-assisted laparoscopic prostatectomy in a 66-year-old man. Anesthetic management was unremarkable. No symptoms were noted by the patient. Postoperative otolaryngology evaluation revealed bilateral ear canal hematomas with intact tympanic membranes. The patient was discharged with Ciprodex ear drops on postoperative day 1. One-month otolaryngology follow-up revealed no long-term sequelae. Although the etiology is unclear, there seems to be a trend in the literature toward occurrence with laparoscopy in the Trendelenburg position. PMID:26361383

    Yokokura, Yuki; Katsura, Seiichiro; Ohishi, Kiyoshi

    A bilateral controller is used to transmit and share haptic information between a master system and a slave system. In a transmission system, the bilateral controller encounters problems in the event of data packet loss and/or disconnections. In this study, a master/slave simulator and environmental data memory are used to solve the problems. In the case of normal operation, the environmental data memory stores force data in a remote side. The control system is operated by the environmental data memory and master/slave simulator when the communication lines are disconnected.

    2015-01-01

    Proboscis lateralis is a very rare congenital craniofacial malformation characterized by a trunk like tubular appendage arising commonly from roof of the orbit near medial canthus. It may be seen as an isolated defect with sporadic occurrence or it may be associated with a spectrum of anomalies. It is usually unilateral and very few bilateral cases of proboscis lateralis have been reported in the literature worldwide. Alobar holoprosencephaly is commonly associated with a single central proboscis and cyclopia. Here we report an unusual case of a bilateral proboscis lateralis seen in association with holoprosencephaly. PMID:26436002

    Morgagni hernia is an unusual congenital herniation of abdominal content through the triangular parasternal gaps of the anterior diaphragm. They are commonly asymptomatic and right-sided. We present a case of a bilateral Morgagni hernia resulting in delayed growth in a 10-month-old boy. The presentation was unique due to its bilateral nature and its symptomatic compression of the mediastinum. Diagnosis was made by 3D reconstructed CT angiogram. The patient underwent medical optimization until he was safely able to tolerate laparoscopic surgical repair of his hernia. Upon laparoscopy, the CT findings were confirmed and the hernia was repaired.

    Hippurate function scintiscans were obtained in prone and standing positions in a group of 76 patients with concurrent hypertension and nephroptosis. Twelve of these patients had massive, bilateral disturbance of intrarenal hippurate transport in the standing position; hippurate transport was normal in the prone position. This pattern was present in only three of 120 normotensive patients with nephroptosis. To investigate the importance of nephroptosis, 87 other hypertensive patients were examined. Eighteen of these patients demonstrated posture-dependent tubular dysfunction, but only four had nephroptosis. The results suggest a direct relationship between bilateral posture-dependent tubular dysfunction and hypertension.

    A female patient suffered from gradual decline of vision for few months. She presented with bilateral multiple pigmented choroidal tumours, associated with overlying retinal changes. The clinical presentation suggested bilateral diffuse uveal melanocytic proliferation (BDUMP) syndrome, which is a paraneoplastic disease, although there was no evidence of any concurrent malignancy. The periodic systemic surveillance that was undertaken for the following 4 years failed to reveal any occult cancer. Nevertheless, there has been relentless progressive deterioration in vision as a consequence of BDUMP syndrome. The management of the declining vision in BDUMP syndrome is challenging and controversial. PMID:24855079

    Variations and anomalies of upper extremities have been commonly reported in routine dissection, clinical practices, and cadaver studies. Despite ongoing research on arterial variations of upper extremities, the absence of bilateral ulnar artery is extremely rare with only 3 patients reported. As the authors are presenting a successfully treated patient, initially prepped for radial forearm osteocutaneous free flap for treatment on oromandibular defect after a wide resection of head and neck cancer lesion, being confirmed to have bilateral ulnar artery hypoplasia and due to this, the patient had to change her surgical plan to fibular osteocutaneous free flap.

    Congenital, infectious, toxic, and demyelinating disorders are common etiological causes of deafness. Tuberculous meningitis, as one of the infectious causes, should be considered in the differential diagnosis since tuberculosis represents an endemic public health problem in developing countries. Multiple cranial nerve palsies can be expected due to basal meningitis; however, presentation with bilateral hearing loss is quite rare. Early diagnosis and treatment are crucial to prevent mortality and residual neurologic deficits. The focus of this discussion is a 42-year-old female presenting with bilateral hearing loss and nonspecific complaints who was finally diagnosed with chronic tuberculous meningitis. We also demonstrate the characteristic radiological and histopathological findings. PMID:25274594

    Congenital bladder diverticulum (CBD) is a very uncommon entity in adults. CBD could be unilateral or bilateral and is caused by a congenital weakness in the bladder musculature. CBD is differentiated from the paraureteral or Hutch type of diverticula. A 42-year-old male presented with bilateral Hutch diverticulum and multiple diverticulum calculus on intravenous pyelography. Cystoscopy revealed bladder diverticulum just medial to the left ureteral orifice with multiple calculi; the patient successfully underwent endoscopic laser cystolithotripsy with resolution of his urinary tract infection. To the best of our knowledge, this is the first case report presenting stone formation of CBD in an adult. PMID:26029313

    2016-01-01

    Introduction. DSM-5 identifies two disorders: somatic symptom disorder and illness anxiety disorder, to replace hypochondriasis in DSM-IV. Patients with both disorders are intensely anxious about the possibility of an undiagnosed illness or devote excessive time and energy to health concerns and are not easily reassured. Both disorders cause considerable distress and life disruption, even at moderate levels. However, hypochondriasis (DSM-IV) is an indication for neither orchidopexy nor orchidectomy. This is the rationale for this report which is the first of its kind to the best of available literature. This is an original case report of interest to a particular clinical specialty of mental health but it will have a broader clinical impact across medicine. Case Presentation. A 30-year-old black male presented to a primary care clinic with multiple internet searches on the topic of testicular pain and its differential diagnosis. He had a bilateral orchidopexy for a suspected torsion. He was referred to mental health unit, to determine fitness for further surgery. Conclusions. If hypochondriasis is suspected in a medical or surgical inpatient, a psychological medicine consultation should be performed, to elucidate the diagnosis, to avoid unnecessary procedures, and to optimize patient's care.

    Purpose: To evaluate the outcome of children with bilateral Wilms’ tumor (BWT) treated on All India Institute of Medical Sciences-Wilms Tumor-99 (AIIMS-WT-99) protocol. Materials and Methods: All children with BWT, registered in our solid tumor clinic from August 1999 through December 2010 were included. Results: Of the 178 fresh cases of Wilms Tumor (WT) treated during this period, 11 (6.2%) had bilateral involvement. All patients except one (12 and 3 cm), had massive bilateral tumors of more than 10 cm on each side. There were eight boys and three girls in the age range 6–30 months. One patient had Denys-Drash syndrome. Twenty renal units were operated upon (12 tumorectomy, five partial nephrectomy, and three nephrectomies), while one patient with inferior vena cava (IVC) thrombus died of renal failure. Tumor spill occurred in three units, lymphnode was positive in two patients. Local recurrence occurred in four patients (six of 18 renal units (33%)—two bilateral and two unilateral). There was one recurrence in the liver that was treated with radio-frequency ablation. The 5-year overall survival (OS) was 90% (95% confidence interval (CI) = 50.8–98.6) and the relapse free survival (RFS) was 38% (95% CI = 6.1–71.6). Conclusion: Massive BWT respond poorly to preoperative chemotherapy, are often not amenable to partial nephrectomy/tumorectomy and have a higher local recurrence rate, giving a poor RFS.

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.

    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. PMID:27096022

    Diaphragmatic paralysis following phrenic nerve injury is a major complication following congenital cardiac surgery. In contrast to unilateral paralysis, patients with bilateral diaphragmatic paralysis present a higher risk group, require different management methods, and have poorer prognosis. We retrospectively analysed seven patients who had bilateral diaphragmatic paralysis following congenital heart surgery during the period from July, 2006 to July, 2014. Considerations were given to the time to diagnosis of diaphragm paralysis, total ventilator days, interval after plication, and lengths of ICU and hospital stays. The incidence of bilateral diaphragmatic paralysis was 0.68% with a median age of 2 months (0.6-12 months). There was one neonate and six infants with a median weight of 4 kg (3-7 kg); five patients underwent unilateral plication of the paradoxical diaphragm following recovery of the other side, whereas the remaining two patients who did not demonstrate a paradoxical movement were successfully weaned from the ventilator following recovery of function in one of the diaphragms. The median ventilation time for the whole group was 48 days (20-90 days). The median length of ICU stay was 46 days (24-110 days), and the median length of hospital stay was 50 days (30-116 days). None of the patients required tracheostomy for respiratory support and there were no mortalities, although all the patients except one developed ventilator-associated pneumonia. The outcome of different management options for bilateral diaphragmatic paralysis following surgery for CHD is discussed. PMID:26345716

    2014-01-01

    Bilateral ureteral obstruction in children is a rare condition arising from several medical or surgical pictures. It needs to be promptly suspected in order to attempt a quick renal function recovery. In this paper we concentrated on uncommon causes of obstruction, with the aim of giving a summary of such multiple, rare and heterogeneous conditions joint together by the common denominator of sudden bilateral ureteral obstruction, difficult to be suspected at times. Conversely, typical and well-known diseases have been just run over. We considered pediatric cases of ureteral obstruction presenting as bilateral, along with some cases which truly appeared as single-sided, because of their potential bilateral presentation. We performed a review of the literature by a search on PubMed, CrossRef Metadata Search, internet and reference lists of single articles updated to May 2014, with no time limits in the past. Given that we deal with rare conditions, we decided to include also papers in non-English languages, published with an English abstract. For the sake of clearness, we divided our research results into 8 categories: (1) urolithiasis; (2) congenital urinary tract malformations; (3) immuno-rheumatologic causes of ureteral obstruction; (4) ureteral localization of infections; (5) other systemic infective causes of ureteral obstructions; (6) neoplastic intrinsic ureteral obstructions; (7) extrinsic ureteral obstructions; and (8) iatrogenic trigonal obstruction or inflammation. Of course, different pathogenic mechanisms underlay those clinical pictures, partly well-known and partly not completely understood. PMID:25374811

  13. Bilateral Control of Master-Slave Systems with Different Scaling

    NASA Astrophysics Data System (ADS)

    Susa, Shigeru; Natori, Kenji; Ohnishi, Kouhei

    Bilateral control is one of control methods used to achieve haptic teleoperation between remote places. If the bilateral system is utilized for small or large environments such as those in brain surgery and space development, it is necessary that the system takes into account scaling factors between the master and slave. In this paper, we propose the bilateral control of master-slave system with different scaling on the basis of reproducibility and operationality which are one of the evaluation indices of bilateral control system. The proposed control system contains two kinds of scaling factors. One of them is scaling factors of position and force responses that are used to determine the scaling ratio between the master and the slave. The other one is used to adjust the control gains at the master and the slave, respectively. In this paper, some scaling types depending on the nominal masses of the systems are proposed. In order to compare the scaling methods, the analysis results of the proposed method on reproducibility and operationality are shown. Moreover, experimental results confirm the validity of the proposed method.

    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.

  2. Bayer bilateral denoising on TriMedia3270

    Digital cameras are now commonly included in several digital devices such as mobile phones. They are present everywhere and have become the principal image capturing tool. Inherent to light and semiconductors properties, sensor noise [10] continues to be an important factor of image quality [12], especially in low light conditions. Removing the noise with mathematical solutions appears thus unavoidable to obtain an acceptable image quality. However, embedded devices are limited by processing capabilities and power consumption and thus cannot make use of the full range of complex mathematical noise removing solutions. The bilateral filter [6] appears to be an interesting compromise between implementation complexity and noise removing performances. Especially, the Bayer [5] bilateral filter proposed in [11] is well adapted for single sensor devices. In this paper, we simulate and optimize the Bayer bilateral filter execution on a common media-processor: the TM3270 [4] from the NXP Semiconductors TriMedia family. To do so we use the TriMedia Compilation System (TCS). We applied common optimization techniques (such as LUT, loop unrolling, convenient data type representation) as well as custom TriMedia operations. We finally propose a new Bayer bilateral filter formulation dedicated to the TM3270 architecture that yields an execution improvement of 99.6% compared to the naÃve version. This improvement results in real-time video processing at VGA resolution at the 350MHz clock rate.

    2015-01-01

    Bow hunter's syndrome is a condition in which vertebrobasilar insufficiency is resultant from head rotation, clinically manifested by presyncopal sensation, syncope, dizziness, and nausea. It is usually diagnosed clinically, with supporting vascular imaging demonstrating an occluded or at the very least compromised unilateral vertebral artery, while the dominant vertebral artery remains patent in the neutral position. Dynamic imaging is utilized to confirm the rotational compression of the dominant vertebral artery. We present the rare case of a patient with typical Bow hunter's symptoms, bilaterally patent vertebral arteries on neutral imaging, and bilateral compromise with head rotation. Our patient underwent posterior decompression of the culprit atlanto-axial transverse foramen and subaxial cervical fusion, with resolution of his symptoms. Our patient exemplifies the possibility of bilateral dynamic vertebral artery occlusion. We show that Bow hunter's syndrome cannot be ruled out in the setting of bilaterally patent vertebral arteries on neutral imaging and that severe cervical spondylosis should impart further clinical suspicion of this unusual phenomenon.

    Introduction & objectives Adaptive deep brain stimulation (aDBS) uses feedback from brain signals to guide stimulation. A recent acute trial of unilateral aDBS showed that aDBS can lead to substantial improvements in contralateral hemibody Unified Parkinson’s Disease Rating Scale (UPDRS) motor scores and may be superior to conventional continuous DBS in Parkinson’s disease (PD). We test whether potential benefits are retained with bilateral aDBS and in the face of concurrent medication. Methods We applied bilateral aDBS in 4 patients with PD undergoing DBS of the subthalamic nucleus. aDBS was delivered bilaterally with independent triggering of stimulation according to the amplitude of β activity at the corresponding electrode. Mean stimulation voltage was 3.0±0.1 volts. Motor assessments consisted of double-blinded video-taped motor UPDRS scores that included both limb and axial features. Results UPDRS scores were 43% (p=0.04; Cohen’s d=1.62) better with aDBS than without stimulation. Motor improvement with aDBS occurred despite an average time on stimulation (ToS) of only 45%. Levodopa was well tolerated during aDBS and led to further reductions in ToS. Conclusion Bilateral aDBS can improve both axial and limb symptoms and can track the need for stimulation across drug states. PMID:26424898

It typically invades contiguous structures at presentation. We report a very rare case of multifocal and ectopic ONB. Case Report: A 41-year-old man presented with left nasal obstruction and occasional left epistaxis associated with headache. Endoscopic examination of the nasal cavities and computed tomography suggested bilateral polypoid masses. Histopathological diagnosis after endoscopic resection established bilateral olfactory neuroblastoma of the ethmoid sinuses. The patient received postoperative radiotherapy. He remains free of disease 4 years after treatment. Conclusions: To the best of our knowledge this is the second documented case of multifocal ectopic olfactory neuroblastoma. Clinicians should consider ONB in the differential diagnosis of bilateral synchronous nasal and paranasal masses to avoid delayed diagnosis. Endoscopic resection of ONB could be an option in selected cases. PMID:27097989

    Bilateral breast cancer incidence is appreciated to be between 0.3 to 12% and is determined either by a hereditary load associated with chromosomal instability under the effect of environmental factors, or by the evolution in a particular hormonal context which gives biological aggressiveness. We present the case of a patient, aged 38 years, clinically, imagistic and bioptic diagnosed with left axillary lymph node metastases of breast carcinoma NST invasive G3, IHC-RE = 60%, RP = 30%, HER2neu = 2 +, Ki67 = 20%, in August 2013. Patient followed neoadjuvant chemotherapy treatment during September-October 2013. In December 2013 she was clinically and imaging diagnosed with bilateral breast cancer, for which surgical intervention was done which consisted of bilateral radical Madden mastectomy with bilateral axillary lymphadenectomy. BAP-invasive carcinoma NST: left breast-pT2mN3a G2, right breast--pT3mN3a G2, IHC-RE = 90%, RP =70% HER2neu = 2 +, Ki67 = 50%. During the period of January-March 2014, the patient followed adjuvant chemotherapy and Herceptin. Bilateral breast ultrasound assessment in April 2014 revealed: left axilla--liquid blade 29 / 6mm; right axilla--oval ganglion 9/5 mm. Abdominal and pelvic ultrasound: empty uterine cavity, bosselated contour; at left ovary level multiple cystic formations. During the period of May-June 2014, adjuvant radiation therapy and ovarian irradiationwas administered to the patient. Subsequently hormone therapy was initiated. Following CHT / ovarian irradiation patient continues to experience intermittent uterine bleeding, which is why a total hysterectomy with bilateral ovariectomy was done, and BAP: cervical, endometrialand left ovary with tumor multifocal infiltration with histopathological aspect of invasive breast carcinoma NST.

    Seeber, Bernhard U.; Baumann, Uwe; Fastl, Hugo

    2004-09-01

    After successful cochlear implantation in one ear, some patients continue to use a hearing aid at the contralateral ear. They report an improved reception of speech, especially in noise, as well as a better perception of music when the hearing aid and cochlear implant are used in this bimodal combination. Some individuals in this bimodal patient group also report the impression of an improved localization ability. Similar experiences are reported by the group of bilateral cochlear implantees. In this study, a survey of 11 bimodally and 4 bilaterally equipped cochlear implant users was carried out to assess localization ability. Individuals in the bimodal implant group were all provided with the same type of hearing aid in the opposite ear, and subjects in the bilateral implant group used cochlear implants of the same manufacturer on each ear. Subjects adjusted the spot of a computer-controlled laser-pointer to the perceived direction of sound incidence in the frontal horizontal plane by rotating a trackball. Two subjects of the bimodal group who had substantial residual hearing showed localization ability in the bimodal configuration, whereas using each single device only the subject with better residual hearing was able to discriminate the side of sound origin. Five other subjects with more pronounced hearing loss displayed an ability for side discrimination through the use of bimodal aids, while four of them were already able to discriminate the side with a single device. Of the bilateral cochlear implant group one subject showed localization accuracy close to that of normal hearing subjects. This subject was also able to discriminate the side of sound origin using the first implanted device alone. The other three bilaterally equipped subjects showed limited localization ability using both devices. Among them one subject demonstrated a side-discrimination ability using only the first implanted device.

    Background: Gangliogliomas are rare low grade, typically well-differentiated, tumors that are composed of mature ganglion cells and neoplastic glial cells. These tumors can appear at virtually any location along the neuroaxis but classically occur in the temporal lobe of young patients. In a small number of cases, gangliogliomas have presented as masses in the brainstem or involving cranial nerves. With the exception of vestibular schwannomas, bilateral tumors in the region of the internal auditory canal (IAC) or cerebellopontine angle (CPA) are exceedingly rare. Case Description: We report a case of a 58-year-old male who presented with hearing loss, tinnitus, and vertigo. Initial magnetic resonance imaging revealed bilateral nonenhancing IAC/CPA tumors. Based on this finding, a presumptive diagnosis of neurofibromatosis Type II was made, which was initially managed conservatively with close observation. He returned for follow-up with worsening vertigo and tinnitus, thus prompting the decision to proceed with surgical resection of the symptomatic mass. Intriguingly, pathological study demonstrated a WHO Grade I ganglioglioma. Description: We report a case of a 58-year-old male who presented with hearing loss, tinnitus, and vertigo.

    Aim: To assess the outcome of patients undergoing bilateral adrenalectomy for Cushing's syndrome (CS). 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. PMID:26693437

    Background Desmoid tumor of the breast is very rare and locally aggressive but has no distant metastasis. Bilateral lesions are extremely rare, found in only 4% of patients. Two cases of bilateral desmoid tumor of the breast are reported. The clinical presentation, diagnosis, imaging, treatment, and follow-up outcomes of recurrence as well as a brief literature review are provided. Case reports Case 1 is a 31-year-old woman who presented with nipple retraction. An ultrasound revealed BIRAD V in both breasts. She underwent a bilateral excisional biopsy under ultrasound mark with the pathology result of extra-abdominal desmoid tumor in both breasts. The patient had a bilateral mastectomy with silicone implantation due to the involved margins by excision. She remained tumor free after 7-year follow-up. Case 2 is a 28-year-old woman who presented with a lump on her right breast that she had discovered ~2 months earlier. An ultrasound showed a spiculated mass in the right breast and some circumscribed hypoechoic masses in both breasts. A bilateral breast excision was done. The pathology result was an extra-abdominal desmoid tumor. She had recurrence on both sides and underwent a mastectomy and silicone implantation. The tumor has not recurred after 1-year follow-up. Conclusion Imaging cannot distinguish between benign breast lesions and malignancy. Pathology results are helpful in making a definitive diagnosis. Given that the desmoid tumor is locally aggressive, a local excision with clear margins is recommended. Chemotherapy and hormonal treatment are controversial. PMID:27578999

    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 < .05). Age, gender, race, income, and education were not statistically significant independent predictors of the utility scores for 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. PMID:27289218

    Magnetoencephalography (MEG) noninvasively measures neuronal activity with high temporal resolution. The aim of this study was to develop a new type of MEG system that can measure bilateral MEG waveforms without a magnetically shielded room, which is an obstacle to reducing both the cost and size of an MEG system. An unshielded bilateral MEG system was developed using four two-dimensional (2D) gradiometers and two symmetric cryostats. The 2D gradiometer, which is based on a low-Tc superconducting quantum interference device and wire-wound pickup coil detects a magnetic-field gradient in two orthogonal directions, or ∂/∂x(∂2Bz/∂z2), and reduces environmental magnetic-field noise by more than 50 dB. The cryostats can be symmetrically positioned in three directions: vertical, horizontal, and rotational. This makes it possible to detect bilateral neuronal activity in the cerebral cortex simultaneously. Bilateral auditory-evoked fields (AEF) of 18 elderly subjects were measured in an unshielded hospital environment using the MEG system. As a result, both the ipsilateral and the contralateral AEF component N100m, which is the magnetic counterpart of electric N100 in electroencephalography and appears about 100 ms after the onset of an auditory stimulus, were successfully detected for all the subjects. Moreover, the ipsilateral P50m and the contralateral P50m were also detected for 12 (67%) and 16 (89%) subjects, respectively. Experimental results demonstrate that the unshielded bilateral MEG system can detect MEG waveforms, which are associated with brain dysfunction such as epilepsy, Alzheimer's disease, and Down syndrome.

    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.

    Guillain-Barre syndrome (GBS) is an acquired immune-mediated inflammatory disorder of the peripheral nervous system. GBS is also called acute idiopathic polyradiculoneuritis. Cranial nerves are affected in over 50% of all cases, with the facial nerves being affected the most. Otherwise, oculomotor nerves affection is rare and might occur in about 10% of cases. In this case report we present 61 years old female with GBS (acute motor and sensory axonal neuropathy subtype) associated with bilateral oculomotor nerve palsy. At the admittance in the neurological status were flaccid paraplegia, tendon reflexes absent at legs and reduced at arms, sensory disturbances in a distal (stocking-glove) distribution and bilateral ptosis. The disease was diagnosed on clinical features, nerve conduction velocity test (NCV), electromyogram (EMG) and cerebrospinal fluid (CSF) tests. After treatment with intravenous immunoglobulins and physical treatment the patient improved. She was able to walk by her own, mild semiptosis remained and she had no paresthesia. PMID:18669237

    Langerhans cell histiocytosis (LCH) is a rare histiocytic disorder with an unpredictable clinical course and highly varied clinical presentation ranging from single system to multisystem involvement. Although head and neck involvement is common in LCH, isolated bilateral temporal bone involvement is exceedingly rare. Furthermore, LCH is commonly misinterpreted as mastoiditis, otitis media and otitis externa, delaying diagnosis and appropriate therapeutic management. To improve detection and time to treatment, it is imperative to have LCH in the differential diagnosis for unusual presentations of the aforementioned infectious head and neck etiologies. Any lytic lesion of the temporal bone identified by radiology should raise suspicion for LCH. We hereby describe the radiologic findings of a case of bilateral temporal bone LCH, originally misdiagnosed as mastoiditis. PMID:24478812

    ABSTRACT Background: The inguinal hernia is one of the most frequent surgical diseases, being frequent procedure and surgeon´s everyday practice. Aim: To present technical details in making hernioplasty using robotic equipment on bilateral inguinal hernia repair with single port and preliminary results with the method. Method: The bilateral inguinal hernia repair was performed by using the Single-Site(c) Da Vinci Surgical Access Platform to the abdominal cavity and the placement of clamps. Results: This technique proved to be effective for inguinal hernia and have more aesthetic result when compared to other techniques. Conclusions: Inguinal hernia repair robot-assisted with single-trocar is feasible and effective. However, still has higher costs needing surgical team special training. PMID:27438038

    Patellar tendon rupture is an uncommon clinical presentation, which generally affects the under 40s who are active in sport. Bilateral rupture of both tendons is much rarer. It occurs most frequently in patients with predisposing factors such as corticosteroid use or systemic diseases. The authors present the case of a 56-year-old male on long-term statin therapy who sustained this injury following a fall on ice. He had no known risk factors for tendon rupture. Surgical treatment involved tendon repair using Krakow suture via bony tunnels in the patella. Statins have previously been associated with tendon ruptures at other sites but there have been no published cases of bilateral patellar tendon rupture linked to statin use. We review the literature regarding the association between statins and tendon rupture. PMID:27165749

    Focal choroidal excavation (FCE) has recently been described as one or more localized areas of choroidal excavation on spectral-domain optical coherence tomography (SD-OCT). The authors describe a case of bilateral FCE in Best vitelliform macular dystrophy (VMD). SD-OCT revealed FCE in both eyes characterized by interruption of the internal segment-outer segment junction and the presence of subretinal hyporeflective space. This is the first report describing bilateral FCE in a distinct macular disorder and specifically with VMD. Future investigations are warranted to ascertain the involvement of other macular dystrophies with atrophic evolution and the impact of FCE on the clinical course.

    The dilated odontoma is an infrequent developmental alteration that appears in any area of the dental arches and can affect deciduous, permanent and supernumerary tooth. Dens invaginatus is a developmental anomaly resulting from invagination of a portion of crown forming within the enamel organ during odontogenesis. The most extreme form of dens invaginatus is known as dilated odontoma. The aim of this case report is to present a rare case of bilateral dilated odontoma affecting a microdontic permanent lateral incisor in a 30 year old female patient with hypodontia and peglateral teeth with its clinical, radiological and histological features, which has yet been not reported. Bilateral presence of dilated odontoma is not a common occurrence, although a single tooth involvement in each case has been reported in the literature. PMID:24348628

    The Achilles tendon is the strongest tendon in the body, which is commonly ruptured in male athletes. Bilateral rupture of the Achilles tendon is a rare condition with very few reported cases in the literature. It poses a challenge in management, and hence, we report a case with traumatic bilateral Achilles tendon rupture in a young male patient and its management. One side was treated conservatively as the rupture was partial and the other side, which had a complete tear, was operated. At nine months follow-up, the patient has had a satisfactory result and is now bearing full weight without any problems. We suggest this method of treatment to be worthwhile for this unusual entity.

    Mounier-Kuhn syndrome is a rare disorder of unknown cause that is characterized by atrophy of the elastic and smooth muscle of the tracheobronchial tree leading to tracheobronchomegaly and bronchiectasis. The syndrome is likely underdiagnosed, because the patients usually present with common respiratory symptoms such as productive cough and usually labeled as chronic obstructive pulmonary disease. Diagnosis is established on the basis of radiologic findings. Association with bilateral vocal cord paralysis has not been described. Treatment is mainly supportive. Symptomatic patients may require endobronchial stenting if airway collapse is encountered. Here, we described a patient who presented with hoarseness and pneumonia. Further studies confirmed the diagnosis of Mounier-Kuhn syndrome with bilateral vocal cord paralysis. PMID:23207474

    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. Histologically, the findings of a papillary pattern of poorly differentiated, mucicarmine-staining cells enclosing gland-like spaces, and the absence of pseudorosettes, melanin, mesenchymal and peripheral neural elements supports an epithelial origin of this tumor. 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. Careful long-term head and neck surveillance is mandatory if early aggressive management of these extremely lethal tumors is to be successful.

    2014-09-01

    Maxillofacial trauma is rare in children younger than the age of 5 years (range 0.6%-1.2%), and they can require different clinical treatment strategies compared with fractures in the adult population because of concerns regarding mandibular growth and development of dentition. A 5-year-old girl with a history of falling from a bicycle 7 hours earlier was referred to the department of oral and maxillofacial surgery. Multislice computed tomographic examination demonstrated a bilateral fracture of the mandibular condyle neck associated with minimal fracture of the alveolar ridge of the maxilla. The multislice computed tomographic scan also demonstrated dislocation on the right condyle neck and, on the left side, a medial inclination of approximately 45 degrees associated with greenstick fracture of the right parasymphysis region. In this particular case, orthodontic rubber elastics in combination with fixed orthodontic brackets provided good results in the treatment of bilateral condyle neck fractures associated with greenstick fracture of parasymphysis.

    2016-07-01

    Carrying a casualty on a stretcher is a critical task within military and emergency service occupations. This study evaluated the impact of manipulating carry speed and the object type in bilateral carries on the ability to predict performance and reflect the physical and physiological requirements of a unilateral stretcher carry. We demonstrated that three task-related predictive tests; a jerry can carry performed at 4.5 km h(-1)or 5.0 km h(-1) and a kettle-bell carry performed at 5.0 km h(-1) were strongly predictive of the physical and physiological demands of an individual participating as part of a four-person stretcher carry team. Therefore, bilateral predictive assessments have the utility for predicting the suitability of employees to effectively and safely conduct a four-person unilateral stretcher carry. PMID:26995042

    Supernumerary teeth are extra teeth in comparison to the normal dentition. Their prevalence varies between 0.1% and 3.8%. Supernumeraries are more common in permanent dentition and its incidence is higher in maxillary incisor region, followed by maxillary third molar and mandibular molar, premolar, canine, and lateral incisor. The prevalence of supernumerary premolars is between 0.075-0.26%, and they may occur in single or multiple numbers Bilateral occurrence is uncommon and large percentage of supernumerary premolars remains impacted, unerupted, and usually asymptomatic; radiograph plays an important role in diagnosis of these. The present paper reports a case of bilaterally impacted completely developed supernumerary premolars associated with common clinical complication in unusual manner along with taurodontism of the upper and lower molars.

    Patients with bilateral high level amputations of the legs are rarely functionally independent after their discharge from hospital. Eighty bilateral amputees were visited by a research physiotherapist, and information was obtained on their family circumstances, accommodation, mobility, and prostheses. A second questionnaire was completed by hospital staff on medical condition, assessments, rehabilitation, and total overall management. The results showed that mobility was severely restricted; out of the 80 patients visited, only 65 could manoeuvre wheelchairs and 23 use prostheses. Accommodation presented difficulties: 34 homes had steps inside and 40 had steps outside. Of the 80 patients seen, 60 could not cope in the bath while 33 were unable to use the lavatory. Assessments and rehabilitation were lacking. There appeared to be little overall management, and hospital staff made only 36 visits to the patient's accommodation before discharge. PMID:6793134

    Katsura, Seiichiro; Ohnishi, Kouhei

    Minimally invasive surgery (MIS) which thinks a great deal of patient’s quality of life (QOL) has attracted attention during about ten years. In this paper, it aims at development of the technology for transmitting force sensation required in medical treatment especially through surgical instruments, such as forceps. In bilateral control, it is a problem how master and slave robots realize the law of action and reaction to the environment. Mechanism of contact with environment and bilateral controller based on stiffness are shown. Master arm in contact with human and slave arm in contact with environment are given compliance, and stable contact with environment can be realized. The proposed method is applied to 3-link master-slave manipulators. As a result, transmission and reproduction of force sensation can be realized. The experimental results show viability of the proposed method.

    During the past decade, advances in techniques and technology led to major changes in cataract surgical practice patterns. In this progression towards ever faster eye rehabilitation after surgery, simultaneous bilateral cataract surgery (SBCS) may be the next and ultimate step. It is not routinely performed: however, there are certain situations in which SBCS might be beneficial to the patients. It has been considered a good option in patients who have significant cataract in both eyes and are not good candidates for having anesthesia and surgery twice. The question is, if the benefits by bilateral surgery justify the risk of simultaneous complications, in particular endophthalmitis. In this perspective we present the clinical, social and economic advantages and disadvantages of such surgical procedures. PMID:17290841

    2016-01-01

    Perinatal testicular torsion (PTT) has poor rates of testicular salvage. Although rare, bilateral PTT carries the risk of anorchia. We present a case of a 2-day-old term infant with acute onset right-sided scrotal discolouration and tenderness. The infant was promptly taken to the operating theatre for emergency scrotal exploration. Bilateral extravaginal testicular torsion was identified, with the right testis appearing to have a more established ischaemic appearance compared to that on the left side. Intraoperative findings were representative of metachronous PTT with a short time period of only several hours separating the torsion events. Both testes were detorted and fixated in the scrotum. The infant made an uneventful recovery. Outpatient clinic review at 6 weeks and 6 months postoperatively confirmed no clinical evidence of testicular atrophy. Given the potential for contralateral torsion and the morbidity of anorchia, our experience supports the role for emergency scrotal exploration in suspected PTT. PMID:27307430

    Abstract Complications following snake bites are not common in France. We report the case of a bilateral pulmonary embolism following a viper envenomation in France. A healthy 72-year-old female presented with a lower limb hematoma following a viper bite. She was admitted at the hospital 2 days later and received low-molecular-weight heparin because of bed rest. Seven days later, she complained of thoracic pain and respiratory failure, and a bilateral pulmonary was diagnosed, without biological sign of neither disseminated intravascular coagulation nor coagulation trouble. Repeated lower limbs Doppler ultrasound were normal. This case is particularly interesting because it is only the 7th reported case of pulmonary embolism following a snake envenomation; moreover, it happened in France where poisonous snakes are very rare. Several hypotheses have been made to explain this late localized coagulopathy: an increased level of unstable fibrin produced by thrombin-like glycoproteins from the venom is one of them.

    Diaphragmatic paralysis is an unusual and often underrecognized cause of dyspnea. We present a case of bilateral diaphragmatic paralysis with no identifiable etiology. Our patient is a 73-year-old female with a history of smoking who presented with dyspnea and orthopnea. She was treated for obstructive lung disease with no improvement in dyspnea despite adequate therapy. She had pulmonary function tests (PFTs) that revealed marked decrease in vital capacity and was unable to perform lung volume maneuvers supine due to marked dyspnea. The maximal inspiratory pressure was 37 in the upright position and decreased to 27 in the supine position. She was given a presumptive diagnosis of idiopathic bilateral diaphragmatic dysfunction. Given the history, physical exam, and PFT findings, we felt that the patient did not need further invasive testing. The patient was treated with noninvasive mechanical ventilation due to hypercapnia and her symptoms improved. PMID:27186002

    The author describes the case of a girl with bilateral persistent pupillary membranes and good visual acuity. An otherwise healthy 10-year-old girl presented with persistent pupillary membranes in both eyes since childhood. The patient had ametropic amblyopia, which was treated with spectacles and part-time occlusion therapy, with the patient responding conventionally. After therapy, her best-corrected visual acuity was 20/25 in both eyes. She had stereopsis of 50 seconds of arc, orthophoria, and normal extraocular movements. The remainder of the examination was normal. Patients with bilateral persistent pupillary membranes may not require surgery if there is adequate opening. The author suggests a trial of refractive correction and occlusion therapy before deciding on surgical and laser intervention, even if it seems an absolute requirement. PMID:19791728

    Introduction: Complete androgen insensitivity syndrome (previously called testicular feminization) is specified by a 46 XY karyotype and negative sex chromatin, bilateral undescended testes, female genitalia appearance, and lack of mullerian derivatives. Case Presentation: A 28-year-old woman with complete (severe) androgen resistance underwent prophylactic laparoscopic bilateral gonadectomy because of the eventually increased risk of gonadal malignancy. Although the gonads appeared grossly normal, microscopic examination revealed bilateral well differentiated sertoli–leydig cell tumor (SLCT). Discussion: Our Medline search revealed that this is the first reported case of bilateral sertoli–leydig cell tumor (SLCT) in androgen insensitivity syndrome. PMID:25032133

Guaifenesin stones were originally reported as complexed with ephedrine, and subsequent reports have demonstrated pure guaifenesin stones, occurring after long term abuse. We report a case of a 23-year-old male who ingested a large, one time dose of guaifenesin, resulting in acute bilateral ureteral obstruction, which, to our knowledge, is the first such reported case in the literature.

    Hypertrophic olivary degeneration is a trans-synaptic neuronal degeneration associated with hypertrophy of the inferior olivary nucleus due to a lesion in the triangle of Guillain-Mollaret. Familiarity with this entity on magnetic resonance imaging (MRI) is essential to avoid other erroneous ominous diagnoses. We present a case of bilateral hypertrophic olivary degeneration and discuss the etiopathogenesis and MRI findings in this entity. The contributory role of MR tractography in the diagnosis is also highlighted. PMID:25489133

    it is difficult to diagnose because of its nonspecific presentation. This condition frequently occurs in association with an extreme physical stress and may lead to acute adrenal insufficiency or death if not promptly and properly treated. We report a rare case of acute bilateral adrenal hemorrhage with adrenal insufficiency following duodenopancreatectomy for ampulloma in absence of surgical complications. Early diagnosis and corticosteroid replacement with aggressive management of the precipitating pathology are essential to enable a successful outcome. PMID:25945442

  13. Bilateral persistent primitive trigeminal arteries associated with trigeminal neuralgia.

    Persistent carotid-vertebrobasilar anastomoses (PCVBA) include the primitive trigeminal artery (PTA), the primitive otic artery (POA), the primitive hypoglossal artery and proatlantal arteries (ProAs). The PTA is the most commonly seen of these accounting for approximately 80-85% of PCVBAs. The PTA which connects the internal carotid artery (ICA) to the basilar artery (BA) may occasionally connect to the superior or posterior inferior cerebellar arteries without interposition to the BA. It is then referred to as a persistent trigeminal artery variant (PTAV), an anomalous carotid-cerebellar anastomosis. Bilateral occurrence of PTA is extremely rare. During vertebral artery (VA) development the anterior radicular artery of segment C1 from the proatlantal artery of Padget evolves into the intradural component of the VA (V4 segment) plus a short extradural segment (distal V3 segment). Agenesis of a single anterior radicular artery of ProA results in the absence of one distal VA associated with an unremarkable contralateral VA and the BA. Absence or hypoplasia of the terminal portion of one VA is a commonly observed anatomic variant. However, absence of the terminal portions of both VAs is exceptional. A rare case of bilateral PTAs is presented with unilateral PTA and a contralateral PTAV causing trigeminal neuralgia. Furthermore, the bilateral PTAs were associated with the absence of the proximal portion of the BA in addition to the bilateral lack of a distal VA. This finding comes as a logical consequence of the developmental anatomy of the vertebrobasilar junction and is consistent with the assumed congenital nature of the anatomic variant. PMID:22113402

    Alkaptonuria ochronosis is a rare metabolic disease in which the body does not have enough enzyme called homogentisic acid oxidase. Due to the homogentisic acid oxidase deficiency, homogentisic acid accumulates in cartilage and connective tissues which leads to ochronotic arthritis. We reported a case of bilateral ochronotic arthritis verified by clinical presentation, imaging, arthroscopic and histological findings. The patient achieved a satisfying therapeutic outcome after arthroscopic debridement followed by intra-articular injection of sodium haluronate. PMID:26221390

    We present experimental and anatomical data from a case study of impaired auditory perception following bilateral hemispheric strokes. To consider the cortical representation of sensory, perceptual, and cognitive functions mediating tonal information processing in music, pure tone sensation thresholds, spectral intonation judgments, and the associative priming of spectral intonation judgments by harmonic context were examined, and lesion localization was analyzed quantitatively using straight-line two-dimensional maps of the cortical surface reconstructed from magnetic resonance images. Despite normal pure tone sensation thresholds at 250-8000 Hz, the perception of tonal spectra was severely impaired, such that harmonic structures (major triads) were almost uniformly judged to sound dissonant; yet, the associative priming of spectral intonation judgments by harmonic context was preserved, indicating that cognitive representations of tonal hierarchies in music remained intact and accessible. Brainprints demonstrated complete bilateral lesions of the transverse gyri of Heschl and partial lesions of the right and left superior temporal gyri involving 98 and 20% of their surface areas, respectively. In the right hemisphere, there was partial sparing of the planum temporale, temporoparietal junction, and inferior parietal cortex. In the left hemisphere, all of the superior temporal region anterior to the transverse gyrus and parts of the planum temporale, temporoparietal junction, inferior parietal cortex, and insula were spared. These observations suggest that (1) sensory, perceptual, and cognitive functions mediating tonal information processing in music are neurologically dissociable; (2) complete bilateral lesions of primary auditory cortex combined with partial bilateral lesions of auditory association cortex chronically impair tonal consonance perception; (3) cognitive functions that hierarchically structure pitch information and generate harmonic expectancies

    Background Essential tremor (ET) is one of the most common hyperkinetic movement disorders. Previous research into the pathophysiology of ET suggested underlying cerebellar abnormalities. Objective In this study, we added electromyography as an index of tremor intensity to functional Magnetic Resonance Imaging (EMG-fMRI) to study a group of ET patients selected according to strict criteria to achieve maximal homogeneity. With this approach we expected to improve upon the localization of the bilateral cerebellar abnormalities found in earlier fMRI studies. Methods We included 21 propranolol sensitive patients, who were not using other tremor medication, with a definite diagnosis of ET defined by the Tremor Investigation Group. Simultaneous EMG-fMRI recordings were performed while patients were off tremor medication. Patients performed unilateral right hand and arm extension, inducing tremor, alternated with relaxation (rest). Twenty-one healthy, age- and sex-matched participants mimicked tremor during right arm extension. EMG power variability at the individual tremor frequency as a measure of tremor intensity variability was used as a regressor, mathematically independent of the block regressor, in the general linear model used for fMRI analysis, to find specific tremor-related activations. Results Block-related activations were found in the classical upper-limb motor network, both for ET patients and healthy participants in motor, premotor and supplementary motor areas. In ET patients, we found tremor-related activations bilaterally in the cerebellum: in left lobules V, VI, VIIb and IX and in right lobules V, VI, VIIIa and b, and in the brainstem. In healthy controls we found simulated tremor-related activations in right cerebellar lobule V. Conclusions Our results expand on previous findings of bilateral cerebellar involvement in ET. We have identified specific areas in the bilateral somatomotor regions of the cerebellum: lobules V, VI and VIII. PMID:26909321

    Glaucoma is one of the leading causes of blindness worldwide. Primary angle closure glaucoma (PACG) is a leading cause ofblindness in East Asian people and known to cause bilateral blindness more frequently than other glaucoma. A retrospective study was thus undertaken to see the visual profile among these cases attending glaucoma unit. Total of 387 cases of angle closure glaucoma were seen in 3 years period. Out of these, 278 (71.8%) were females and 109 were males (28.2%). Among total cases, 61.5% had chronic angle closure glaucoma (CACG) and 38.5% had acute angle closure glaucoma (AACG) in one or both eyes. Bilateral angle closure attack was encountered simultaneously in 16 of the total acute angle closure cases accounting for 10.7%. Vision evaluation at the time of diagnosis among chronic angle closure glaucoma revealed blindness in 97 patients accounting for 20.4%. In acute glaucoma cases, after breaking the acute attack, the prevalence of blindness was found to be 8.9% out of total cases. Bilateral blindness was seen in 17.6% of total cases presented with either acute attack or chronic glaucoma. Mean intraocular pressure (IOP) was 32 mmHg (SD = 9.456) and 44 mmHg (8.67) in CACG and AACG respectively. Cataract was associated in 15.1% of CACG and 12.8% of AACG. Cataract related blindness was presumed to be present in only 4.1% cases of CACG and 14.3% of AACG cases who were blind. (p = < 0.001) Angle closure glaucoma is the frequent cause of bilateral blindness. PMID:17203819

    Background: Parkinson's disease (PD), the most common basal ganglia degenerative disease, affects balance control, especially when patients change balance strategy during postural tasks. Bilateral chronic stimulation of the subthalamic nucleus (STN) is therapeutically useful in advanced PD, and reduces the motor signs of patients. Nevertheless, the effects of STN stimulation on postural control are still debatable. Aims: To assess the impact of bilateral STN stimulation on balance control in PD and to determine how basal ganglia related sensorimotor modifications act on neurosensorial organisation of balance and motor postural programming. Methods: Twelve subjects aged 45–70 years underwent unified Parkinson's disease rating scale motor (part III) clinical tests, static and dynamic posturography, including sensory organisation and adaptation tests, shortly before and six months after bilateral implantation of electrodes into the STN. Results: The postoperative static test showed an improvement in postural control precision both in eyes open and eyes closed conditions. The dynamic test highlighted the decreased number of falls and the ability of the patients to develop more appropriate sensorimotor strategies when stimulated. The sensory organisation test showed an improvement of equilibrium score and, thus, a better resolution of sensorial conflicts. Conclusions: STN stimulation allowed a reduction in rigidity and therefore an improvement in the ability to use muscular proprioception as reliable information, resulting in vestibulo-proprioceptive conflict suppression. STN stimulation has a synergistic effect with levodopa for postural control. Accordingly, non-dopaminergic pathways could be involved in postural regulation and STN stimulation may influence the functioning of these pathways. PMID:15897498

    Khosla, Rohit K.; McGregor, Jyoti; Kelley, Patrick K.; Gruss, Joseph S.

    2012-01-01

    The bilateral cleft lip and nasal deformity presents a complex challenge for repair. Surgical techniques continue to evolve and are focused on primary anatomic realignment of the tissues. This can be accomplished in a single-stage or two-stage repair early in infancy to provide a foundation for future growth of the lip and nasal tissue. Most cleft surgeons currently perform a single-stage repair for simplifying patient care. Certain institutions utilize presurgical orthopedics for alignment of the maxillary segments and nasal shaping. Methods for the bilateral cleft lip repair are combined with various open and closed rhinoplasty techniques to achieve improved correction of the primary nasal deformity. There is recent focus on shaping the nose for columellar and tip support, as well as alar contour and alar base position. The authors will present a new technique for closure of the nasal floor to prevent the alveolar cleft fistula. Although the alveolar fistula is closed, alveolar bone grafting is still required at the usual time in dental development to fuse the maxilla. It is paramount to try and minimize the stigmata of secondary deformities that historically have been characteristic of the repaired bilateral cleft lip. A properly planned and executed repair reduces the number of revisions and can spare a child from living with secondary deformities. PMID:24179448

    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. PMID:23387809

    Summary: In this case report we describe a rare case of bilateral diaphragmatic dysfunction due to Lyme disease. Case report: A 62-years-old male presented to the hospital because of flu-like symptoms. During initial evaluation a bilateral diaphragmatic weakness with orthopnea and nocturnal hypoventilation was observed, without a known aetiology. Bilateral diaphragmatic paralysis was confirmed by fluoroscopy with a positive sniff test. The patient was referred to our centre for chronic non-invasive nocturnal ventilation (cNPPV). Subsequent investigations revealed evidence of anti- Borrelia seroactivity in EIA-IgG and IgG-blot, suggesting a recent infection with Lyme disease, and resulted in a 4-week treatment with oral doxycycline. The symptoms of nocturnal hypoventilation were successfully improved with cNPPV. However, our patient still shows impaired diaphragmatic function but he is no longer fully dependent on nocturnal ventilatory support.     Conclusion: Lyme disease should be considered in the differential diagnosis of diaphragmatic dysfunction. It is a tick-borne illness caused by one of the three pathogenic species of the spirochete Borrelia burgdorferi, present in Europe. A delay in recognizing the symptoms can negatively affect the success of treatment. Non-invasive mechanical ventilation (NIV) is considered a treatment option for patients with diaphragmatic paralysis. PMID:25671085

  17. Simultaneous bilateral total ankle replacement using a 3-component prosthesis

    PubMed Central

    2011-01-01

    Background and purpose Total ankle replacement is an established surgical procedure in patients with end-stage ankle osteoarthritis. We analyzed complications and medium-term results in patients with simultaneous bilateral total ankle replacement. Patients and methods 10 women and 16 men, mean age 60 (SD 13) years, were followed for a median of 5 (2–10) years. Results There were no intraoperative or perioperative complications, with the exception of 1 patient with prolonged wound healing. Major revision surgery was necessary in 6 of the 52 ankles, including 4 revisions of prosthetic components. The average pain score decreased from 6.9 (4−10) to 1.8 (0−4) points. The American Orthopaedic Foot and Ankle Society hindfoot score increased from 32 (SD 14) points preoperatively to 74 (SD 12) points postoperatively. The average range of motion increased from 28° (SD 12) preoperatively to 38° (SD 9) postoperatively. All 8 categories of SF-36 score improved. Interpretation Simultaneous bilateral total ankle replacement is a suitable method for restoration of function and attainment of pain relief in patients with bilateral end-stage ankle osteoarthritis. The results of this procedure, including complication rates, revision rates, and functional outcome, are comparable to those reported in patients with unilateral total ankle replacement.

  18. Fast O1 bilateral filtering using trigonometric range kernels.

    PubMed

    Chaudhury, Kunal Narayan; Sage, Daniel; Unser, Michael

    2011-12-01

    It is well known that spatial averaging can be realized (in space or frequency domain) using algorithms whose complexity does not scale with the size or shape of the filter. These fast algorithms are generally referred to as constant-time or O(1) algorithms in the image-processing literature. Along with the spatial filter, the edge-preserving bilateral filter involves an additional range kernel. This is used to restrict the averaging to those neighborhood pixels whose intensity are similar or close to that of the pixel of interest. The range kernel operates by acting on the pixel intensities. This makes the averaging process nonlinear and computationally intensive, particularly when the spatial filter is large. In this paper, we show how the O(1) averaging algorithms can be leveraged for realizing the bilateral filter in constant time, by using trigonometric range kernels. This is done by generalizing the idea presented by Porikli, i.e., using polynomial kernels. The class of trigonometric kernels turns out to be sufficiently rich, allowing for the approximation of the standard Gaussian bilateral filter. The attractive feature of our approach is that, for a fixed number of terms, the quality of approximation achieved using trigonometric kernels is much superior to that obtained by Porikli using polynomials.

    Bilateral vestibular failure (BVF) is a severe chronic disorder of the labyrinth or the eighth cranial nerve characterized by unsteadiness of gait and disabling oscillopsia during head movements. According to animal data, vestibular input to the hippocampus is proposed to contribute to spatial memory and spatial navigation. Except for one seminal study showing the association of impaired spatial navigation and hippocampal atrophy, patient data in BVF are lacking. Therefore, we performed a voxel-wise comparison of the hippocampal gray matter volume (GMV) in a clinically representative sample of 27 patients with incomplete BVF and 29 age- and gender-matched healthy controls to test the hypothesis of hippocampal atrophy in BVF. Although the two groups did not generally differ in their hippocampal GMV, a reduction of GMV in the bilateral hippocampal CA3 region was significantly correlated with increased vestibulopathy-related clinical impairment. We propose that GMV reduction in the hippocampus of BVF patients is related to the severity of vestibular-induced disability which is in line with combined hippocampal atrophy and disorders of spatial navigation in complete vestibular deafferentation due to bilateral nerve section. Clinically, however, the most frequent etiologies of BVF cause incomplete lesions. Accordingly, hippocampus atrophy and deficits in spatial navigation occur possibly less frequently than previously suspected. Hum Brain Mapp 37:1998-2006, 2016. © 2016 Wiley Periodicals, Inc.

    The following case report describes a 1-year-old female cheetah (Acinonyx jubatus) with bilateral blindness and unresponsive pupils. For comparison, a second healthy 2.5-year-old male cheetah without visual deficits was also examined. Clinical examination of both animals included biomicroscopy, indirect ophthalmoscopy, tonometry, and electroretinography. The young female cheetah showed no menace response, no direct or indirect pupillary light reflex, and no dazzle reflex in either eye. Fundus lesions, as detected by indirect ophthalmoscopy, are described for the female animal. In both eyes, the fundus color was green/turquoise/yellow with multiple hyperpigmented linear lesions in the tapetal area around the optic nerve. The optic nerve head was dark gray and about half the normal size suggesting bilateral optic nerve hypoplasia and retinal dysplasia or differentially optic nerve atrophy and chorioretinal scarring. The ERG had low amplitudes in the right eye but appeared normal in the left eye compared with the male cheetah. Blood levels did not suggest current taurine deficiency. This is addressed to some degree in the discussion. Bilateral optic nerve hypoplasia or optic nerve atrophy is a rare anomaly in cats and has not yet been described in a cheetah. PMID:20840102

    Introduction Posterior dislocation of the shoulder is a rare and commonly missed injury. Unilateral dislocations occur mostly due to trauma. Bilateral posterior shoulder dislocations are even more rare and result mainly from epileptic seizures. Electrical injury is a rare cause of posterior shoulder dislocation. Injury mechanism in electrical injury is similar to epileptic seizures, where the shoulder is forced to internal rotation, flexion and adduction. Presentation of case This report presents a case of bilateral posterior shoulder dislocation after electrical shock. We were able to find a few individual case reports describing this condition. The case was acute and humeral head impression defects were minor. Our treatment in this case consisted of closed reduction under general anesthesia and applying of orthoses which kept the shoulders in abduction and external rotation. A rehabilitation program was begun after 3 weeks of immobilization. After 6 months of injury the patient has returned to work. 20 months postoperatively, at final follow-up, he was painless and capable of performing all of his daily activities. Discussion The amount of bilateral shoulder dislocations after electrical injury is not reported but is known to be very rare. The aim of this case presentation is to report an example for this rare entity, highlight the difficulties in diagnosis and review the treatment options. Conclusion Physical examination and radiographic evaluation are important for quick and accurate diagnosis. PMID:26904192

    Human children with cochlear implants represent a unique population of individuals who have undergone variable amounts of auditory deprivation prior to being able to hear. Even more unique are children who received bilateral cochlear implants (BICIs), in sequential surgical procedures, several years apart. Auditory deprivation in these individuals consists of a two-stage process, whereby complete deafness is experienced initially, followed by deafness in one ear. We studied the effects of post-implant experience on the ability of deaf children to localize sounds and to understand speech in noise. These are two of the most important functions that are known to depend on binaural hearing. Children were tested at time intervals ranging from 3-months to 24-months following implantation of the second ear, while listening with either implant alone or bilaterally. Our findings suggest that the period during which plasticity occurs in human binaural system is protracted, extending into middle-to-late childhood. The rate at which benefits from bilateral hearing abilities are attained following deprivation is faster for speech intelligibility in noise compared with sound localization. Finally, the age at which the second implant was received may play an important role in the acquisition of binaural abilities. [Work supported by NIH-NIDCD.

    Introduction: Tuberculous otitis media (TOM) is an uncommon, insidious, and frequently misdiagnosed form of tuberculosis (TB). In particular, TOM is usually secondary to direct transmission from adjacent organs, while the primary form has been rarely reported. The main aim of treatment is to start the patient on an antitubercular regime and early surgical intervention to decompress the facial nerve if involved. Case Report: The case report of a twenty year-old male with bilateral tuberculous otitis media, who presented himself with fever followed by sequential bilateral facial nerve paralysis, bilateral profound hearing loss, and abdominal tuberculosis leading to intestinal perforation, is presented. To the best available knowledge and after researching literature, no such case depicting the extensive otological complications of tuberculosis has been reported till date. Conclusion: Tuberculosis of the ear is a rare entity and in most cases the clinical features resemble that of chronic otitis media. The diagnosis is often delayed due to varied clinical presentations and this can lead to irreversible complications. Early diagnosis is essential for prompt administration of antitubercular therapy and to prevent complications. PMID:26082906

    This paper presents the design and validation of a control system for a pair of powered knee and ankle prostheses to be used as a prosthetic intervention for bilateral transfemoral amputees. The control system leverages communication between the prostheses for enhanced awareness and stability, along with power generation at the knee and ankle joints to better restore biomechanical functionality in level ground walking. The control methodology employed is a combination of an impedance-based framework for weight-bearing portions of gait and a trajectory-based approach for the non-weight-bearing portions. The control system was implemented on a pair of self-contained powered knee and ankle prostheses, and the ability of the prostheses and control approach to provide walking functionality was assessed in a set of experimental trials with a bilateral transfemoral amputee subject. Specifically, experimental data from these trials indicate that the powered prostheses and bilateral control architecture provide gait kinematics that reproduce healthy gait kinematics to a greater extent than the subject’s daily-use passive prostheses.

    Five bilateral cochlear implant users were tested for their localization abilities and speech understanding in noise, for both monaural and binaural listening conditions. They also participated in lateralization tasks to assess the impact of variations in interaural time delays (ITDs) and interaural level differences (ILDs) for electrical pulse trains under direct computer control. The localization task used pink noise bursts presented from an eight-loudspeaker array spanning an arc of approximately 108° in front of the listeners at ear level (0-degree elevation). Subjects showed large benefits from bilateral device use compared to either side alone. Typical root-mean-square (rms) averaged errors across all eight loudspeakers in the array were about 10° for bilateral device use and ranged from 20° to 60° using either ear alone. Speech reception thresholds (SRTs) were measured for sentences presented from directly in front of the listeners (0°) in spectrally matching speech-weighted noise at either 0°, +90° or -90° for four subjects out of five tested who could perform the task. For noise to either side, bilateral device use showed a substantial benefit over unilateral device use when noise was ipsilateral to the unilateral device. This was primarily because of monaural head-shadow effects, which resulted in robust SRT improvements (P<0.001) of about 4 to 5 dB when ipsilateral and contralateral noise positions were compared. The additional benefit of using both ears compared to the shadowed ear (i.e., binaural unmasking) was only 1 or 2 dB and less robust (P=0.04). Results from the lateralization studies showed consistently good sensitivity to ILDs; better than the smallest level adjustment available in the implants (0.17 dB) for some subjects. Sensitivity to ITDs was moderate on the other hand, typically of the order of 100 μs. ITD sensitivity deteriorated rapidly when stimulation rates for unmodulated pulse-trains increased above a few hundred Hz but at

    The number of injuries that force golfers to quit is also increasing. In particular, the upper body injuries are concerns for amateur golfers. This study was conducted not only to investigate muscular balance, such as ipsilateral and bilateral ratios of the upper body, but to also evaluate the possible problems of muscular joints in amateur golfers. Male golfers (n=10) and a healthy control group (n=10) were recruited for the assessment of muscular function in the upper body, which was measured by an isokinetic dynamometer at 60°/sec. The tested parts were trunk, wrist, forearm, elbow, and shoulder joints. Mann-Whitney U-test was used to evaluate the significance of the differences between groups. The ipsilateral ratios of peak torque or work per repetition (WR) of trunk flexor and extensor in the golfers were not significantly different compared to those of the control group. These results were similar to the shoulder horizontal abductor and adductor. However, there were significant differences in the ipsilateral and bilateral ratios of the wrist, forearm, and elbow joints. Especially, the WR of the wrist flexor, forearm pronator, and elbow flexor on the left side of amateur golfers showed imbalances in bilateral ratios. Moreover, the WR of the wrist and elbow flexors on the left side of amateur golfers were lower than those of the wrist and elbow extensors. Therefore, amateur golfers should strive to prevent injuries of the wrist, forearm, and elbow joints and to reinforce the endurance on those parts of the left side. PMID:27162771

    Studies of manual wheelchair propulsion often assume bilateral symmetry to simplify data collection, processing, and analysis. However, the validity of this assumption is unclear. Most investigations of wheelchair propulsion symmetry have been limited by a relatively small sample size and a focus on a single propulsion condition (e.g., level propulsion at self-selected speed). The purpose of this study was to evaluate bilateral symmetry during manual wheelchair propulsion in a large group of subjects across different propulsion conditions. Three-dimensional kinematics and handrim kinetics along with spatiotemporal variables were collected and processed from 80 subjects with paraplegia while propelling their wheelchairs on a stationary ergometer during three different conditions: level propulsion at their self-selected speed (free), level propulsion at their fastest comfortable speed (fast), and propulsion on an 8% grade at their level, self-selected speed (graded). All kinematic variables had significant side-to-side differences, primarily in the graded condition. Push angle was the only spatiotemporal variable with a significant side-to-side difference, and only during the graded condition. No kinetic variables had significant side-to-side differences. The magnitudes of the kinematic differences were low, with only one difference exceeding 5°. With differences of such small magnitude, the bilateral symmetry assumption appears to be reasonable during manual wheelchair propulsion in subjects without significant upper-extremity pain or impairment. However, larger asymmetries may exist in individuals with secondary injuries and pain in their upper extremity and different etiologies of their neurological impairment. PMID:26125019

    The purpose of this study was to evaluate the long-term follow-up results of subcutaneous venous ports implanted in patients with bilateral mastectomies. We retrospectively reviewed the hospital charts and the electronic database of 17 patients with bilateral mastectomies whom had venous port implantation in our interventional radiology suit. A total of 17 ports were implanted to the paramedian (n = 3) and anterolateral (standard; n = 12) chest wall, on the trapezius muscle (n = 1), and to the antecubital fossa (n = 1). The mean age was 48.29 years (range: 35-60 years). The mean time interval from time of surgery to port implantation was 34 months (range: 1-84 months). The mean follow-up time was 15 months (range: 7-39 months). Follow-up parameters and classification of the complications was defined according to the SIR guidelines. No procedure-related complication occurred. A single case of mild late infection was noted and the infection rate was 0.19/1000 catheter days. Infusion chemotherapy administration was still going on in eight patients. Two patients died during the follow-up and four patients were lost after 6 months. Port removal was performed in three patients at follow-up because of the end of treatment. One trapezius port and one paramedian port weres among the removed ports without any problem. Although we have a limited number of patients, port placement to the anterior chest wall, either paramedian or anterolateral, on the trapezius muscle or to the antecubital fossa depending on the extent of the bilateral breast surgeries that can be performed with low complication rates by a careful patient and anatomical location selection by involving the patients in the decision-making process. We believe that patient education and knowledge of possible complications have high importance in follow-up.

    Purpose: To determine the etiology, clinical features and outcomes of bilateral vitreous hemorrhage (VH) in children. Methods: This retrospective chart review was performed on patients with bilateral VH under the age of 18 at a tertiary eye care center in India. Data included demographics, details of history and ocular examination, reports of investigations, surgeries or other interventions performed, and final anatomical and visual outcomes. Patients were divided into two groups i.e., traumatic and non-traumatic (spontaneous). Results: The traumatic group was comprised of 37 patients including 27 male and 10 female subjects with mean age of 13.47 ± 5.31 years, the most common complaint was decreased vision (96.45%) and the most prevalent etiology was firecracker injury in 16 (43.2%) patients. Mean baseline visual acuity (VA) was 2.34 ± 1.31 logMAR which was significantly improved to 1.08 ± 0.23 logMAR (P = 0.042). The mean number of surgeries was 2.72 ± 1.43 in the traumatic VH and mean follow up period was 23.14 ± 6.54 months. The spontaneous group included 48 subjects comprised of 27 male and 21 female cases with mean age of 14.48 ± 2.03 years. The most common cause was vasculitis in 21 (43.75%) subjects including four patients with tuberculosis. Mean baseline VA was 1.97 ± 1.13 logMAR which showed a significant improvement to 0.82 ± 0.24 logMAR (P = 0.012) after mean follow up of 34.2 ± 11.2 months. Eleven patients required at least one major surgery. Conclusion: Vasculitis was the most common cause of spontaneous bilateral VH; traumatic VH most prevalently occurred due to firecracker injury. Final VA was better in the spontaneous group. PMID:26425315

    Our main objective is to report the feasibility of performing simultaneous robotic-assisted laparoscopic (RAL) heminephrectomy with contralateral ureteroureterostomy in children with bilateral duplicated systems. Three female children with bilateral congenital renal/ureteral anomalies underwent concurrent RAL simultaneous unilateral partial nephrectomy with ureterectomy and contralateral ureteroureterostomy with redundant ureterectomy using a four/five-port approach. Mean age at repair was 32.9 months (range 7-46 months) and mean weight was 13.7 kg (range 10.4-13.6 kg). The RAL heminephroureterectomy and contralateral ureteroureterostomy were performed via a four-port approach (five ports in one patient), and the patients were repositioned and draped when moving to the other side. Mean operative time was 446 min (range 356-503 min). Mean estimated blood loss was 23.3 cc (range 10-50 cc). Postoperative length of stay for two patients was 2 days and 1 day for one patient (mean = 1.7 days). Mean length of follow-up was 18.3 months (range 7-36 months). No significant intraoperative or postoperative complications occurred for any of the three patients. Two children had no hydronephrosis on postoperative imaging in follow-up, and one child had a small stable, residual pararenal fluid collection on the side of heminephrectomy. Two patients underwent postoperative ureteral stent removal under general anesthesia. In children with bilateral duplicated urinary tract with ureterocele, ectopic ureter, and/or vesicoureteral reflux, laparoscopic repair with robotic assistance can be accomplished safely in a single operative procedure with a short hospital stay.

Chest radiograph revealed the above findings, later confirmed by computed tomography. He was in shock and also had gastrointestinal (GI) bleeding and renal dysfunction. With adequate resuscitative measures including fluids, blood transfusions, intercostal tube drainage and mechanical ventilation he made a complete recovery. Good prognostic indicators in near drowning patients include higher Glasgow Coma Scale, short submersion time and quick resuscitative measures even in the presence of serious cardiorespiratory or hemodynamic compromise.

    Wernicke's encephalopathy is a life-threatening neurologic complication of thiamine deficiency. Though the presentation of symptoms can vary widely, the classical triad is founded on ophthalmoplegia, alteration of mental status, and gait disturbance. We describe a case of Wernicke's encephalopathy in an oncology patient shortly after concurrent 5-fluorouracil, carboplatin, and radiotherapy for locally advanced oropharyngeal cancer, presenting as complete bilateral blindness, ataxia, nystagmus, and confusion. Thiamine was given based on clinical suspicion and rapid improvement of clinical findings occurred. An MRI performed later supported the diagnosis of Wernicke's encephalopathy. A multifactorial etiology of thiamine deficiency from nutritional deficits and neurotoxic effects of chemotherapy are hypothesized. PMID:26623207

    STUDY QUESTION Is bilateral tubotubal anastomosis a successful treatment in an outpatient patient population? SUMMARY ANSWER For women wanting children after tubal sterilization, bilateral tubotubal anastomosis is an effective outpatient treatment. WHAT IS KNOWN ALREADY With the current emphasis in reproductive medicine on high technology procedures, the effectiveness of female surgical sterilization reversal is often overlooked. Previous clinical studies of tubal sterilization reversal have been mostly retrospective analyses of small patient populations. STUDY DESIGN, SIZE, DURATION A cohort of women who underwent outpatient bilateral tubotubal anastomosis from January 2000 to June 2013 was followed prospectively until December 2014 to determine the proportions of women undergoing the procedure who became pregnant and who had live births. Data were collected at the time of pregnancy. Differences in pregnancy rates and live birth rates associated with age, race and sterilization method were evaluated. PARTICIPANTS/MATERIALS, SETTING, METHODS A total of 6692 women, aged 20–51 years, underwent outpatient bilateral tubotubal anastomosis. MAIN RESULTS AND THE ROLE OF CHANCE The crude overall pregnancy rate was 69%. The crude overall birth rate was 35%. Results varied according to age at sterilization reversal and the method of sterilization. Women under 30 years of age at reversal of ring/clip sterilizations had an 88% pregnancy rate and 62% birth rate. Pregnancy and birth rates declined as age increased at sterilization reversal. Coagulation sterilization reversals resulted in the lowest rates of pregnancies and births. Ligation/resection reversals had intermediate success rates. LIMITATIONS, REASONS FOR CAUTION Limitations of our study include probable underreporting of pregnancies based on patient-initiated reports; possible errors in the reporting of pregnancies or early miscarriages that may have been based solely on home pregnancy tests; and probable over

She underwent pars plana vitrectomy surgery combined with endolaser photocoagulation and silicone oil tamponade in the right eye. A week later, pneumatic retinopexy was done in the left eye. As the retinal tear did not seal, 360° scleral buckling surgery was performed and retina was attached. Bilateral simultaneous rhegmatogenous retinal detachment after LASIK for correction of myopia can be a serious complication. Patients should be informed about the possibility of this complication.

    Simultaneous bilateral facial paralisis (SBFP) occurs in 0.3-2% of all facial paralisis. We report a case of SBFP in association with Lyme disease. A review of literature about SBFP is made, studing specially the one caused by Borrelia burgdorferi. We present a diagnostic guideline of SBFP. Suspect diagnosis of Lyme disease is based on clinical and epidemiological criteria. Culture isolation of this bacteria is difficult, therefore serologic testing is required. Neuroborreliosis treatment is intravenous Ceftriaxone or Cefotaxime. Oral Doxycycline is useful in the treatment of neuritis without central nervous system involvement. PMID:15566265

    The precedence effect (PE) enables the perceptual dominance by a source (lead) over an echo (lag) in reverberant environments. In addition to facilitating sound localization, the PE can play an important role in spatial unmasking of speech. Listeners attending to binaural vocoder simulations with identical channel center frequencies and phase demonstrated PE-based benefits in a closed-set speech segregation task. When presented with the same stimuli, bilateral cochlear implant users did not derive such benefits. These findings suggest that envelope extraction in itself may not lead to a breakdown of the PE benefits, and that other factors may play a role. PMID:26723365

    Medial medullary syndrome (MMS) is a rare type of stroke which results due to occlusion of the anterior spinal artery or vertebral artery or its branches. In this case report we present a patient who developed MMS secondary to Takayasu arteritis (TA). TA is a chronic inflammatory arteritis primarily involving the arch of aorta and its branches, which in our patient resulted in occlusion of subclavian arteries as well as infarction of the medial medulla bilaterally. To our knowledge this is the first time that MMS has been found to occur secondary to TA. PMID:23943806

    2016-01-01

    ABSTRACT Leber hereditary optic neuropathy (LHON) causes visual loss, predominantly in healthy young men. We recently examined a patient who previously had bilateral macular holes and subsequently developed LHON at 74 years of age. Although his central scotomas were initially attributed to the macular holes, his visual acuity declined following an initial improvement after operative closure of the macular holes; thus, other diagnoses, including LHON, were considered. Furthermore, macular optical coherence tomography (OCT) images remained unchanged in this time. A mitochondrial genetic analysis identified a 11778G→A mutation. From this case, we propose that LHON remains in the differential diagnosis even in older patients, as has previously been reported. PMID:27335507

    Acquired emphysema is a rare pathology in pediatrics. We report the case of a patient born at term with a neonatal respiratory distress, which had required mechanical ventilation. She developed gradually chronic obstructive pulmonary disease with severe emphysematous lesions, respiratory failure and functional impairments. Bilateral emphysema resection, performed at 16 years old, allowed major functional benefits at rest and during exercise. We present the results of respiratory functional evaluations, walk tests and maximal exercise tests (including measure of dynamic hyperinflation) before and after surgery, which highlights that surgery is a successful option in the treatment of compressive emphysema in childhood.

    We present clinical and magnetic resonance (MR) findings in three patients with segmental myoclonia occurring 11-18 months after severe brainstem injury. Palatal myoclonus and vertical ocular myorhythmia were present in all three patients and synchronous involuntary movements of the upper extremities ("wing beating") in two patients. MR-imaging showed multiple post-traumatic lesions within the dentato-rubro-olivary pathway ("myoclonic triangle"), associated with bilateral enlargement and increased signal intensity of the inferior olives. The signal abnormality was more prominent on proton density weighted images than on T2-weighted images, suggesting underlying pathological changes different from typical gliosis. PMID:8356884

    2011-01-01

    Bilateral temporomandibular joint (TMJ) luxation was diagnosed postmortem in a female, 6-mo-old CD rat (Rattus norvegicus) after probable head entrapment and subsequent disentanglement from a protective jacket. Clinical antemortem signs included inability to close her mouth, prehend food and drink water, anxiety, and linear skin erosions extending down the right and left commissures of the mouth. Radiography revealed rostral displacement of the mandible with concomitant malocclusion. The combination of clinical signs, acute nature of the presentation, and torn appearance of the protective jacket were strongly indicative of a traumatic etiology. To our knowledge, this is the first reported case of TMJ luxation in a rat. PMID:22330578

    The clinical syndrome of a 65-year-old patient with a slit-shaped right-sided meso-diencephalic lesion was analysed. A cerebellar syndrome with limb-kinetic ataxia, intention tremor and hypotonicity in all extremities as well as ataxic dysarthria was found. The disruption of the two cerebello-(rubro)-thalamic pathways probably explained the signs of bilateral cerebellar dysfunction. The uncrossed ascending limb of the right, and the crossed one of the left brachium conjunctivum may have been damaged by the unilateral lesion extending between caudal midbrain and dorsal thalamus.

    A master controller for a mechanically dissimilar bilateral slave servo-manipulator is disclosed. The master controller includes a plurality of drive trains comprising a plurality of sheave arrangements and cables for controlling upper and lower degrees of master movement. The cables and sheaves of the master controller are arranged to effect kinematic duplication of the slave servo-manipulator, despite mechanical differences there between. A method for kinematically matching a master controller to a slave servo-manipulator is also disclosed. 13 figs.

    In the field of teleoperation, visual or tactile information obtained by the operators is restricted (e. g., limited or delayed sight) because of communication constraints. Therefore, it is difficult for the operators to operate the system. In this paper, a bilateral control system using the environmental information about the position and posture of a target as obtained by a camera is proposed. The proposed method reduces the workload of the operators by taking some of their tasks. An experiment is conducted to prove the benefit of the proposed method by using a 1-DOF master robot and a 2-DOF slave robot.

    Recently, minimally invasive surgery (MIS) has become apparent. Research has been performed on surgical robots needed in MIS. In the case of MIS, it is effective to express environmental impedance as numerical data in order to preserve it for establishing standard reference values of the conditions of internal organs. In this paper, we propose a novel method for the estimation of stiffness in real environments in which bilaterally controlled robots are needed. By using the proposed method, environmental stiffness can be estimated dynamically regardless of the initial position of slave system. The viability of the proposed method is confirmed from the experimental results.

    Ghosh, Chiranjit; Mondal, Pradeep Kumar

    2014-01-01

    Supernumerary teeth are considered as one of the most significant dental anomalies during the primary and early mixed dentition stages. They are of great concern to the dentists and parents because of the eruption, occlusal, and esthetic problems they can cause. Supernumerary teeth occur more frequently in the permanent dentition but rarely in primary dentition and more often seen in males. A supernumerary tooth in the primary dentition can cause ectopic or delayed eruption of permanent central incisors which will further alter occlusion and may compromise esthetics and formation of dentigerous cysts. Here we discuss a case of bilateral supernumerary teeth in deciduous dentition in a female child. PMID:24995257

    Purpose. To report a case of transient lymphoid hyperplasia presenting as bilateral nodular scleral mass in a young male patient. Design. Observational case report. Methods. Chart review. Causes of scleritis were considered and excluded based on detailed history, physical examination, and laboratory investigations. Results. Excisional biopsy of scleral lesions indicated lymphoid tissue. Immunohistochemical studies revealed a polyclonal population of T and B cells consistent with a benign reactive process. Conclusions. Chronic exposure of the ocular adnexa to many allergens and irritants may lead to activation of the inflammatory cascade. In severely allergic patients activation may be exponential and elicit an immune-mediated response resulting in a transient lymphoid reactive process. PMID:26421203

    Verrucous epidermal nevi are congenital, noninflammatory cutaneous hamartomas composed of keratinocytes. They follow the lines of Blaschko and show hyperkeratosis without cellular atypia. The routine histology shows variable amount of hyperkeratosis, acanthosis and papillomatosis and rarely epidermolytic hyperkeratosis. We saw a 3-year-old boy with bilaterally symmetrical, systematized verrucous plaques along the lines of Blaschko extensively involving the trunk and extremities but sparing the face and palmoplantar skin. Histopathology showed features of epidermal nevi with prominent epidermolytic hyperkeratosis. We report here the case for the rarity of this entity. PMID:26288413

  16. Bilateral and multiple cavitation sounds during upper cervical thrust manipulation

    PubMed Central

    2013-01-01

    Background The popping produced during high-velocity, low-amplitude (HVLA) thrust manipulation is a common sound; however to our knowledge, no study has previously investigated the location of cavitation sounds during manipulation of the upper cervical spine. The primary purpose was to determine which side of the spine cavitates during C1-2 rotatory HVLA thrust manipulation. Secondary aims were to calculate the average number of pops, the duration of upper cervical thrust manipulation, and the duration of a single cavitation. Methods Nineteen asymptomatic participants received two upper cervical thrust manipulations targeting the right and left C1-2 articulation, respectively. Skin mounted microphones were secured bilaterally over the transverse process of C1, and sound wave signals were recorded. Identification of the side, duration, and number of popping sounds were determined by simultaneous analysis of spectrograms with audio feedback using custom software developed in Matlab. Results Bilateral popping sounds were detected in 34 (91.9%) of 37 manipulations while unilateral popping sounds were detected in just 3 (8.1%) manipulations; that is, cavitation was significantly (P < 0.001) more likely to occur bilaterally than unilaterally. Of the 132 total cavitations, 72 occurred ipsilateral and 60 occurred contralateral to the targeted C1-2 articulation. In other words, cavitation was no more likely to occur on the ipsilateral than the contralateral side (P = 0.294). The mean number of pops per C1-2 rotatory HVLA thrust manipulation was 3.57 (95% CI: 3.19, 3.94) and the mean number of pops per subject following both right and left C1-2 thrust manipulations was 6.95 (95% CI: 6.11, 7.79). The mean duration of a single audible pop was 5.66 ms (95% CI: 5.36, 5.96) and the mean duration of a single manipulation was 96.95 ms (95% CI: 57.20, 136.71). Conclusions Cavitation was significantly more likely to occur bilaterally than unilaterally during upper cervical HVLA

    A 21-year-old woman developed simultaneous rhegmatogenous retinal detachment after laser in situ keratomileusis (LASIK) in both eyes. She underwent pars plana vitrectomy surgery combined with endolaser photocoagulation and silicone oil tamponade in the right eye. A week later, pneumatic retinopexy was done in the left eye. As the retinal tear did not seal, 360° scleral buckling surgery was performed and retina was attached. Bilateral simultaneous rhegmatogenous retinal detachment after LASIK for correction of myopia can be a serious complication. Patients should be informed about the possibility of this complication.

    The occurrence impacted teeth, single or multiple is very common. But, phenomenon of kissing molars is an extremely rare phenomenon. Mandibular third molars are the most common impacted teeth. Mandibular first or second molars does not share the same frequency of occurrence. But, there are rare cases in which the occlusal surfaces of impacted molars are united by the same follicular space and the roots point in the opposite direction, and are termed as kissing molars. Sometimes, these teeth will be associated with pathologies. This article reports a rare case of mandibular bilateral kissing molars. PMID:25918627

    Atlantoaxial rotatory fixation (AARF), which is a dislocation or subluxation of the atlantoaxial joint, is a well-recognized condition in children. We present a case of AARF after otoplastic surgery for bilateral cryptotia performed by plastic surgeons. The pediatric patient presented with neck pain and torticollis after the surgery, and an orthopedic surgeon diagnosed AARF. The patient was treated successfully with conservative treatment incorporating mild manual manipulation, neck traction, and a collar for 1.5 months. Physicians should consider the possibility of AARF when a patient presents with neck pain and torticollis after otoplastic surgery; diagnosis and treatment should be started immediately.

    Bilateral internal mammary artery (BIMA) grafts are used for coronary revascularisation by only a minority of surgeons, despite a growing body of evidence suggesting improved survival when compared to use of only one internal mammary artery with additional saphenous vein grafts. Herein we review the evidence supporting revascularisation with BIMA and suggest reasons why the majority of surgeons use only one internal mammary artery. We discuss technical considerations, various graft combinations and the use of BIMA to facilitate anaortic off-pump coronary artery bypass (OPCAB). PMID:23977638

    Interdisciplinary approach for the management of malocclusion provides a holistic approach of patient management. Prudent treatment planning is necessary to achieve the various treatment goals. This case report describes the orthodontic management of a 16-year-old adolescent female patient with bilateral labially impacted maxillary canines. The problems associated with impacted maxillary canines and the biomechanical interventions used for this patient are discussed. The treatment protocol involved surgical intervention, followed by sequential traction of the impacted teeth. An interdisciplinary approach to treatment with different mechanical strategies led to the achievement of the desired esthetic, functional, and occlusal treatment goals. PMID:25395776

    Pseudohypoaldosteronism type 1 (PHA-1) is a rare salt-wasting syndrome caused by a peripheral resistance to aldosterone. Here, we describe an unusual presentation of the autosomal dominant PHA-1 featuring bilateral pneumothoraces at birth, thrombocytosis in infancy, and hypercalcemia in addition to the well-described findings of hyponatremia, hyperkalemia, and failure to thrive. These findings contribute to the limited case descriptions of PHA-1 and may suggest additional diagnostic considerations in a neonate presenting with hyperkalemia, hyponatremia, and failure to thrive.

    1992-05-01

    The objective of this project was to develop a bilateral six degree-of-freedom telerobotic component assembly station utilizing remote stereo vision assisted control. The component assembly station consists of two Unimation Puma 260 robot arms and their associated controls, two Panasonic miniature camera systems, and an air compressor. The operator controls the assembly station remotely via kinematically similar master controllers. A Zenith 386 personal computer acts as an interface and system control between the human operator's controls and the Val II computer controlling the arms. A series of tasks, ranging in complexity and difficulty, was utilized to assess and demonstrate the performance of the complete system.

    Chylothorax is accumulation of chylous fluid in the pleural space due to impaired integrity of the thoracic duct or its branches. In childhood, the causes differ from those in adults because children less frequently develop malignancies and are more resistant to trauma. Commonly, chylothorax occurs as a complication of tumoral invasion or cardiopulmonary surgery. Treatment of chylothorax is essentially medical. In the event of medical treatment failure or a massive effusion, surgery is needed. We describe the case of a 65-year-old woman who developed bilateral chylothorax after a simple cough. She was treated with a medium-chain triglyceride diet and thoracentesis. PMID:24928644

She progressively developed severe somnolence with marked abulia, right hemiparesis, right hemianopsia, and pseudobulbar palsy. Brain magnetic resonance imaging showed the rare image of bilateral acute anterior choroidal artery infarction. Pseudobulbar mutism and in rare cases abulia have been described in acute anterior choroidal artery infarction contralateral to an older lesion in mirror position. Although neurologic deterioration is not infrequent in anterior choroidal artery territory infarcts, the absence of focal neurologic signs on admission is rare and did not raise suspicion of acute stroke.

Plain radiography and magnetic resonance imaging demonstrated bilateral distal patellar tendon avulsions without fracture of the tibial tuberosities and the physes. To our knowledge, this particular injury has not been previously described in the literature. Open surgeries and internal fixation were performed with excellent functional outcome. This type of injury was similar to the well-recognised acute tibial tuberosity avulsion fracture in terms of the pathogenesis and treatment. We propose a further subtype of this injury pattern.

There were very few reports about urinary tract infections such as renal abscess, perinephric abscess, and emphysematous pyelonephritis complicated with psoas muscle abscess; however, psoas muscle abscess associated with emphysematous cystitis has not yet been reported. Here, we report a case of bilateral posas muscle abscess following emphysematous cystitis in an 81-year-old nondiabetic man, who was treated successfully with prolonged antibiotic therapy and supportive care. Early recognition of psoas muscle abscess can prevent aggressive interventional procedure and warrant good prognosis. PMID:25755669

    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. PMID:27298913

    Accessory breast is a rare entity that can present as asymptomatic masses or can cause symptoms like heaviness, pain, restriction of arm movement and limitation in daily pursuits with allied apprehension and anxiety for the patient. We present a case of bilateral axillary masses mimicking as accessory breast with multiple fibroadenoma in a 28 years, nulliparous, Indian woman who is HIV positive, which proves to be a diagnostic dilemma. Excisional biopsy was diagnostic. The rarity of such cases imposes challenges on the management in terms of diagnosis, prognosis and therapeutic options. PMID:23813993

    A 31-year-old woman was referred to our hospital with symptoms of hypertension and bilateral adrenocortical masses with no feature of Cushing syndrome. The serum aldosterone/renin ratio was elevated and the saline loading test showed no suppression of the plasma aldosterone level, consistent with a diagnosis of primary hyperaldosteronism. Overnight and low-dose dexamethasone suppression tests showed no suppression of serum cortisol, indicating a secondary diagnosis of subclinical Cushing syndrome. Adrenal vein sampling during the low-dose dexamethasone suppression test demonstrated excess secretion of cortisol from the left adrenal mass. A partial right adrenalectomy was performed, resulting in normalization of blood pressure, hypokalemia, and high aldosterone level, implying that the right adrenal mass was the main cause of the hyperaldosteronism. A total adrenalectomy for the left adrenal mass was later performed, resulting in a normalization of cortisol level. The final diagnosis was bilateral adrenocortical adenomas, which were secreting aldosterone and cortisol independently. This case is the first report of a concurrent cortisol-producing left adrenal adenoma and an aldosterone-producing right adrenal adenoma in Korea, as demonstrated by adrenal vein sampling and sequential removal of adrenal masses.

    A leading neurological hypothesis for autism postulates amygdala dysfunction. This hypothesis has considerable support from anatomical and neuroimaging studies. Individuals with bilateral amygdala lesions show impairments in some aspects of social cognition. These impairments bear intriguing similarity to those reported in people with autism, such as impaired recognition of emotion in faces, impaired theory of mind abilities, failure to fixate eyes in faces, and difficulties in regulating personal space distance to others. Yet such neurological cases have never before been assessed directly to see if they meet criteria for autism spectrum disorders (ASD). Here we undertook such an investigation in two rare participants with developmental-onset bilateral amygdala lesions. We administered a comprehensive clinical examination, as well as the Autism Diagnostic Observation Schedule (ADOS), the Social Responsiveness Scale (SRS), together with several other standardized questionnaires. Results from the two individuals with amygdala lesions were compared with published norms from both healthy populations as well as from people with ASD. Neither participant with amygdala lesions showed any evidence of autism across the array of different measures. The findings demonstrate that amygdala lesions in isolation are not sufficient for producing autistic symptoms. We suggest instead that it may be abnormal connectivity between the amygdala and other structures that contributes to autistic symptoms at a network level. PMID:20700516

    An 80-year-old right-handed man suddenly became impossible to recognize any color 7 years prior to admission. He complained that everything looked like of the same color, monochromatic. On admission, he could not discriminate any color and any familial face. Left homonymous hemianopsia associated with right lower partial visual filed defect was observed, but visual acuity of both eyes was well preserved. Visual-visual color tasks (Ishihara, matching, Hue test, Panel-D15) disclosed the disturbances in color perception. However, he could roughly distinguished red or brown from the other colors. The color test was also impaired regarding the visual-verbal color tasks (naming, pointing). However, verbal description of the color concept, which was shown by the verbal-verbal color tasks, was well preserved. In addition, we observed left hemispatial neglect, disturbance of face recognition and topographical disorientation. MRI revealed old hemorrhagic infarcts in the bilateral occipital and temporal lobes, including the bilateral lateral and medial occipito-temporal gyri. Disturbance of color recognition in this case was diagnosed as cerebral achromatopsia on the basis of clinical characteristics and MRI findings. This is the first case of cerebral achromatopsia of which lesions were detected by MRI in detail. PMID:1628452

  5. Comparison of Interaural Electrode Pairing Methods for Bilateral Cochlear Implants

    PubMed Central

    Dietz, Mathias

    2015-01-01

    In patients with bilateral cochlear implants (CIs), pairing matched interaural electrodes and stimulating them with the same frequency band is expected to facilitate binaural functions such as binaural fusion, localization, and spatial release from masking. Because clinical procedures typically do not include patient-specific interaural electrode pairing, it remains the case that each electrode is allocated to a generic frequency range, based simply on the electrode number. Two psychoacoustic techniques for determining interaurally paired electrodes have been demonstrated in several studies: interaural pitch comparison and interaural time difference (ITD) sensitivity. However, these two methods are rarely, if ever, compared directly. A third, more objective method is to assess the amplitude of the binaural interaction component (BIC) derived from electrically evoked auditory brainstem responses for different electrode pairings; a method has been demonstrated to be a potential candidate for bilateral CI users. Here, we tested all three measures in the same eight CI users. We found good correspondence between the electrode pair producing the largest BIC and the electrode pair producing the maximum ITD sensitivity. The correspondence between the pairs producing the largest BIC and the pitch-matched electrode pairs was considerably weaker, supporting the previously proposed hypothesis that whilst place pitch might adapt over time to accommodate mismatched inputs, sensitivity to ITDs does not adapt to the same degree.

    Traumatic brain injuries (TBIs) affect millions of people each year. Research investigating repeated or serial damage in the form of lesions indicates that behavioral deficits are reduced in animals given sequential lesions separated by a sufficient period of recovery. In the lesion literature, this phenomenon is known as the serial lesion effect (SLE). Although the SLE phenomenon is established in the lesion literature, it has not been thoroughly investigated under current models of brain injury. In the current study, a controlled cortical impact of the bilateral frontal cortex was performed in either a single procedure or a serial procedure separated by two weeks. Rats were tested on the Morris water maze, bilateral tactile adhesive removal task, rotarod and Barnes maze task to determine behavioral deficits. Histology was performed to determine lesion size and astrocyte and microglial response. A serial lesion effect was demonstrated across a majority of the behavioral tasks. However, histological analyses did not suggest a clear mechanistic link to the behavioral phenomena. This is the first study to demonstrate the SLE in a model of TBI, suggesting that behavioral deficits may actually be reduced in repeated head injuries, given an adequate time window between injuries.

    A 31-year-old woman had bilateral retinoblastoma diagnosed in early childhood. The right eye was enucleated at the age of 1 year, and the left eye was treated with radiation therapy (a total dose of 16,000 rad). Twenty-three years later, in 1975, a subcutaneous mass was noted in the left periorbital region. A biopsy specimen of the mass was taken and a diagnosis of pleomorphic postradiation sarcoma was made. Electron microscopic studies of the periorbital mass confirmed the diagnosis of leiomyosarcoma. After additional radiation therapy, the residual mass was surgically excised. Five years later, a right renal mass, which histologically proved to be a renal cell carcinoma, was discovered. She was treated with nephrectomy, radiation, and chemotherapy. A recent follow-up examination disclosed that the patient is alive and apparently without any evidence of metastatic disease, 30 years after the diagnosis of bilateral retinoblastoma was made. The literature is reviewed regarding postradiation sarcomas and the occurrence of second malignant neoplasms in patients with retinoblastoma.

    A patient who had disseminated vascular tumors involving the bilateral ovaries, bilateral lungs and pleura, pericardium, and mediastinum is reported. The tumors were histologically of the capillary, and partly the cavernous, type of hemangioma. However, endothelial cell growth was prominent in some areas, especially in the lung, and the histology of the lung tumor resembled epithelioid hemangioendothelioma or intravascular bronchiolo-alveolar tumor (IVBAT). In the endocardium of the right atrium, an endothelial tumorous projection was observed, and there were tiny foci of tumor cell nests in the abdominal venous wall. Small lymphangiomas were also found in the subcapsular region of the spleen. These findings suggest that there had been an abnormal proliferation of systemic endothelial cells and that tumors of endothelial cell origin with diverse histological patterns developed with this condition as a background. The autopsy finding of fibrin thrombi in multiple organs as well as laboratory data including thrombocytopenia suggest that this case belongs to the "Kasabach-Merritt syndrome." PMID:3673576

    Objective The aim of this study was to evaluate the results of bilateral sacrospinous fixation (SSF), which was performed with surgical mesh interposition and bilateral vaginal repair. Material and Methods Twenty-two patients underwent SSF between 2010 and 2012, and the results were evaluated retrospectively. The results at preoperative and postoperative 6th, 12th, and 18th months of the pelvic organ prolapse quantification system (POP-Q) and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12 (PISQ-12) were compared using Friedman and Wilcoxon Signed Ranks tests. Values of p<0.05 and <0.01 were considered statistically significant. Results According to the POP-Q, significant healing was observed on all vaginal vault points (p=0.001), and no prolapse was observed until the 18-month follow-up stage. There were also prominent patients who felt satisfactory with respect to their sexual life according to PISQ-12 (p=0.001). Conclusion This technique appears to provide an adequate clinical resolution, and it may be the primary surgical option for women with pelvic organ prolapse. PMID:26097393

    Bilateral recurrent laryngeal nerve (RLN) injury is rare for benign thyroid lesions (0.2%). After extubation-stridor, respiratory distress, aphonia occurs due to the closure of the glottic aperture necessitating immediate intervention and emergency intubation or tracheostomy. Intra-operative identification and preservation of the RLN minimizes the risk of injury. It is customary to expect RLN problems after thyroid surgery especially if malignancy, big thyroid, distorted anatomical problems and difficult airway that can lead to intubation trauma. Soon after extubating, it is essential to the anesthetist to check the vocal cord movements on phonation and oropharyngeal reflexes competency. But this case is specially mentioned to convey the message that in spite of absence of above mentioned predisposing factors for complications and good recovery profile specific to thyroid, there can be unanticipated airway compromise that if not attended to immediately may cost patient's life. This is a case of postextubation stridor following subtotal thyroidectomy due to bilateral RLN damage and its management. PMID:26417137

    Globalization and technological revolutions are making the world more interconnected. International trade is an important approach linking the world. Since the 2011 Tohoku earthquake and tsunami in Japan shocked the global supply chain, more attention has been paid to the global impact of large-scale disasters. China is the second largest trader in the world and faces frequent natural disasters. Therefore, this study proposes a gravity model for China's bilateral trade tailored to national circumstances and estimates the impact of natural disasters in China and trading partner countries on Chinese imports and exports. We analyzed Chinese and trading partner statistical data from 1980 to 2012. Study results show the following: (1) China's natural disasters have a positive impact on exports but have no significant impact on imports; (2) trading partner countries' natural disasters reduce Chinese imports and exports; (3) both development level and land area of the partners are important in determining the intensity of natural disaster impacts on China's bilateral trade. The above findings suggest that the impact of natural disasters on trade is asymmetric and significantly affected by other factors, which demand further study.

    Objective: Spontaneous pneumothorax is a disease that may cause serious respiratory distress and can be a life-threatening condition. A total of 1.3% of all spontaneous pneumothorax cases are simultaneous bilateral spontaneous pneumothorax (SBSP). In this study, because of its rarity, we discuss SBSP cases in light of previously reported cases. Materials and Methods: Between January 2004 and December 2009, SBSP was detected in five patients. Results: All patients were male, and the mean patient age was 18.6 (between 16 and 22 years of age). All patients had various degrees of dyspnea and chest pain. All diagnoses were established by chest X-rays. Two patients (40%) had primary spontaneous pneumothorax (PSP), and three (60%) had secondary spontaneous pneumothorax (SSP) (two patients had silicosis, and one had Staphylococcus aureus pneumonia). Previously, bilateral tube thoracostomies were performed on all patients. One PSP patient had a left apical pleurectomy with axillary thoracotomy; the other had a right apical pleurectomy. Tetracycline pleurodesis was performed on one of the silicosis patients. No additional surgical procedure or pleurodesis was performed on the other silicosis patient or on the pneumonia patient. No recurrence of pneumothorax was observed in any patient. Conclusions: SBSP could be a life-threatening condition; therefore, urgent diagnosis and appropriate treatment of this condition can save patients’ lives. PMID:25610108

    The acronym PHACE has been used to denote a constellation of abnormalities: posterior fossa anomalies, facial hemangiomas, arterial anomalies, cardiac anomalies, and eye abnormalities. Approximately 30% of patients with large facial hemangiomas have PHACE syndrome, with the vast majority having intracranial arteriopathy. Few reports characterize neurological deterioration from this intracranial arteriopathy, and even fewer report successful treatment thereof. The authors report on a case of a child with PHACE syndrome who presented with an ischemic stroke from a progressive intracranial arteriopathy and describe her successful treatment with bilateral pial synangiosis. An 8-month old girl diagnosed with PHACE syndrome was found to have bilateral internal carotid artery stenosis. Although initially asymptomatic, a few months after diagnosis she suffered a right frontal and parietal stroke. MRI and cerebral angiography investigations demonstrated progressive intracranial arterial stenosis and occlusion. The patient then underwent indirect cerebral revascularization surgery. At 2-year follow-up, she exhibited clinical improvement with persistent speech and motor developmental delay. Follow-up MRI and cerebral angiography showed no new ischemic events and robust extensive vascular collateralization from surgery. PHACE syndrome is an uncommon disease, and affected patients often have cerebral arteriopathy. Although the underlying natural history of cerebral arteriopathy in PHACE remains unclear, cerebral revascularization may represent a potential therapy for symptomatic patients. PMID:26405843

    Purpose. To report a case of bilateral Coats' disease combined with retinopathy of prematurity (ROP). Case. Retinal vascularization was complete in the right eye, whereas zone III, stage 3 ROP and preplus disease were observed in the left eye at 43 weeks of postmenstrual age (PMA) in a 31-week premature, 1200-g neonate. Intraretinal exudates developed and retinal hemorrhages increased in the left eye at 51 weeks of PMA. Diode laser photocoagulation (LP) was applied to the left eye. Exudates involved the macula, and telangiectatic changes developed one month following LP. Additional LP was applied to the left eye combined with intravitreal bevacizumab (IVB) injection at 55 weeks of PMA. Disease regressed one month after the additional therapy. At the 14-month examination of the baby, telangiectatic changes and intraretinal exudates were observed in the right eye. Diode LP was applied to the right eye combined with IVB injection. Exudates did not resolve completely, and cryotherapy was applied one month following LP. Retinal findings regressed three months following the cryotherapy. Conclusion. This is the first report of presumed bilateral Coats' disease combined with ROP. If Coats' disease could be diagnosed at early stages, it would be a disease associated with better prognosis.

    We present a study of the bilateral symmetry of human breast hemoglobin saturation maps measured with a broadband optical mammography instrument. We have imaged 21 patients with unilateral breast cancer, 32 patients with unilateral benign lesions, and 27 healthy patients. An image registration process was applied to the bilateral hemoglobin saturation (SO 2 SO2 ) images by assigning each pixel to the low, middle, or high range of SO 2 SO2 values, where the thresholds for the categories were the 15th and 85th percentiles of the individual saturation range. The Dice coefficient, which is a measure of similarity, was calculated for each patient’s pair of right and left breast SO 2 SO2 images. The invasive cancer patients were found to have an average Dice coefficient value of 0.55±0.07 0.55±0.07 , which was significantly lower than the benign and healthy groups (0.61±0.11 0.61±0.11 and 0.62±0.12 0.62±0.12 , respectively). Although differences were seen in a group analysis, the healthy patient Dice coefficients spanned a wide range, limiting the diagnostic capabilities of this SO 2 SO2 symmetry analysis on an individual basis. Our results suggest that for assessing the SO 2 SO2 contrast of breast lesions, it may be better to select a reference tissue in the ipsilateral rather than the contralateral breast. PMID:26849841

    The classical accelerated Demons algorithm uses Gaussian smoothing to penalize oscillatory motion in the displacement fields during registration. This well known method uses the L2 norm for regularization. Whereas the L2 norm is known for producing well behaving smooth deformation fields it cannot properly deal with discontinuities often seen in the deformation field as the regularizer cannot differentiate between discontinuities and smooth part of motion field. In this paper we propose replacement the Gaussian filter of the accelerated Demons with a bilateral filter. In contrast the bilateral filter not only uses information from displacement field but also from the image intensities. In this way we can smooth the motion field depending on image content as opposed to the classical Gaussian filtering. By proper adjustment of two tunable parameters one can obtain more realistic deformations in a case of discontinuity. The proposed approach was tested on 2D and 3D datasets and showed significant improvements in the Target Registration Error (TRE) for the well known POPI dataset. Despite the increased computational complexity, the improved registration result is justified in particular abdominal data sets where discontinuities often appear due to sliding organ motion.

    Proximal humerus fracture represents five to eight percent of all fractures and is twice as common in women than in men. Most cases of displaced fracture of the proximal humerus are treated surgically; it is probable that more cases are preferred to be treated surgically greater than required. The optimal treatment for these fractures remains controversial, but physicians have a tendency to treat via open reduction and fixation with angular locking plates or glenohumeral arthroplasty.  We present a case of a 71-year-old woman with bilateral displaced proximal humeral fracture. Conservative treatment was initiated with two hanging casts, achieving radiological reduction on week one. After two additional weeks of casting, treatment continued with radiologic control and home physical therapy, ultimately an excellent functional outcome and adequate radiological reduction was obtained.    Even in bilaterally displaced proximal humerus fractures, conservative treatment can be an efficient option, reducing complications, reaching adequate functional results and acceptable radiographic reduction.​ PMID:27489750

    The cortical representation of eye position is still uncertain. In the monkey a proprioceptive representation of the extraocular muscles (EOM) of an eye were recently found within the contralateral central sulcus. In humans, we have previously shown a change in the perceived position of the right eye after a virtual lesion with rTMS over the left somatosensory area. However, it is possible that the proprioceptive representation of the EOM extends to other brain sites, which were not examined in these previous studies. The aim of this fMRI study was to sample the whole brain to identify the proprioceptive representation for the left and the right eye separately. Data were acquired while passive eye movement was used to stimulate EOM proprioceptors in the absence of a motor command. We also controlled for the tactile stimulation of the eyelid by removing from the analysis voxels activated by eyelid touch alone. For either eye, the brain area commonly activated by passive and active eye movement was located bilaterally in the somatosensory area extending into the motor and premotor cytoarchitectonic areas. We suggest this is where EOM proprioception is processed. The bilateral representation for either eye contrasts with the contralateral representation of hand proprioception. We suggest that the proprioceptive representation of the two eyes next to each other in either somatosensory cortex and extending into the premotor cortex reflects the integrative nature of the eye position sense, which combines proprioceptive information across the two eyes with the efference copy of the oculomotor command.

    Introduction The abducent nucleus is located in the upper part of the rhomboid fossa beneath the fourth ventricle in the caudal portion of the pons. The abducent nerve courses from its nucleus, to innervate the lateral rectus muscle. This nerve has the longest subarachnoid course of all the cranial nerves, it is the cranial nerve most vulnerable to trauma. It has been reported that 1% to 2.7% of all head injuries are followed by unilateral abducent palsy, but bilateral abducent nerve palsy is extremely rare. Case Presentation A 65-year-old woman presented to the emergency department following a motor vehicle accident. A neurological assessment showed the patient’s Glascow coma scale (GCS) to be 15. She complained of double vision, and we found lateral gaze palsy in both eyes. A hangman fracture type IIA (C2 fracture with posterior ligamentous C1 - C2 distraction) was found on the cervical CT scan. A three-month follow-up of the patient showed complete recovery of the abducent nerve. Conclusions Conservative treatment is usually recommended for traumatic bilateral abducent nerve palsy. Our patient recovered from this condition after three months without any remaining neurological deficit, a very rare outcome in a rare case. PMID:27218062

    A healthy 40-year-old man, restrained in the front passenger seat, suffered visually disabling blunt ocular trauma following spontaneous release of the passenger side air-bag module, during vehicular deceleration, without an automobile crash. Though the driver-side airbag was also released, the driver was unharmed. The passenger suffered bilateral hyphema, bilateral vitreous hemorrhage and suspected posterior scleral rupture in the left eye and also had an eyebrow laceration, from impact with the dashboard panel covering the air-bag module, which was detached by the force of airbag deployment. This is the first reported case from West Africa and the first case in which part of the airbag module detached to cause additional trauma. This report adds to the growing burden of evidence world-wide, for a review of the safety aspects of the automobile airbag. This case clearly illustrates that although airbags reduce mortality, they carry a high risk of ocular morbidity, even with seat belt restraint. PMID:24791116

    Management of severe ovarian hyperstimulation syndrome (OHSS) includes hospitalization for fluid and electrolyte management. Abdominal paracentesis is also used as minimally invasive form of management in selected cases of severe OHSS following ovulation induction. However, if pregnancy ensues, the syndrome persists for a longer period, and the clinical manifestations of severe OHSS could mask the picture of a bleeding gestational sac. It could be easily overlooked unless the possibility of an ectopic pregnancy is kept in mind in cases of severe OHSS exacerbated by early pregnancy with or without a previous ectopic pregnancy history. We report a case of severe OHSS with simultaneous bilateral tubal pregnancy following intrauterine insemination (IUI). A 31-year-old woman with polycystic ovarian disease developed severe OHSS during the therapeutic course of IUI. An emergent exploratory laparotomy was performed 14 days after admission, and the operative findings showed persistent profuse bleeding from the bilateral fimbrial ends with marked enlargement of the ampullary portions. A linear salpingotomy was performed by a longitudinal incision along the area of maximal distension of the dilated fallopian tubes to preserve her fertility. We recommend that in cases of severe OHSS exacerbated by early pregnancy, serial serum beta-hCG and transvaginal ultrasound follow-up may be necessary due to the potential association of severe OHSS in pregnancy with an ectopic pregnancy.

    In children, fracture-separation of the epiphyseal plate near the elbow joint is a common occurrence. However, separation of the distal humeral epiphysis is very rare, and in most cases, it is caused by high-impact trauma. In all reported cases, there has been a clear mechanism of injury. We report a case of an 11-year-old male patient who sustained separation of the distal humeral epiphyses bilaterally after 2 years of gymnastics, without a clear mechanism of injury. This patient had been using the vault since he was 9 years old, although children of that age do not normally perform on the vault. When gymnasts place their hands on the vault with their elbows flexed and subsequently extend their elbows to push off, the biomechanical load is placed equally on the right and left arms. Consequently, this type of repeated stress induces injury to the epiphyseal cartilages bilaterally, resulting in chronic progression of separation of the distal humeral epiphyses. PMID:25438108

    Simultaneous bilateral hip fractures are rare, mostly being caused by violent forces or in patients with bone metabolism disorders. We present the case of an elderly patient who sustained simultaneous bilateral hip fractures following a simple fall without having any known predilecting comorbidities other than advanced age. Only four cases have been described of elderly patients without comorbidity with simultaneous bilateral hip fractures following low-energy traumas. This rareness potentially leads to misses of this diagnosis. PMID:27161143

    This paper proposes a bilateral control method for a teleoperation system with different sizes and work volumes. In the proposed controller, transformer-type bilateral control and gyrator-type bilateral control are integrated. The proposed control method can be used for the control of the motion of a slave robot; this involves intuitive manipulation of the master robot despite the structural difference between the master and slave.

    Inguinal hernias may contain urinary bladder as one of its contents, but very rarely have it as sole content. Inguinal vesical hernias may be unilateral or bilateral. When bilateral, inguinal vesical hernia may produce "pelvic Mickey mouse sign." This case reinforces the "pelvic Mickey mouse sign" in bilateral inguinal hernia containing only urinary bladder as content, which has been described only once before. PMID:26775075

    Bilateral patellar tendon ruptures are rare. The majority of case reports describing bilateral patellar tendon ruptures have occurred in patients with predisposing factors to tendinopathy. We describe a case of bilateral patellar tendon rupture sustained following minimal trauma by a patient with no systemic disease or history of steroid use. Due to the rarity of this injury, clinical suspicion is low. It is reported that 38% of patellar tendon ruptures are misdiagnosed initially. Therefore careful history taking and physical examination is integral in ensuring a diagnosis is achieved for early primary repair. We discuss the aetiology of spontaneous tendon rupture and report a literature review of bilateral patellar tendon ruptures. PMID:27200200

    We report a 57-year-old man with bilateral cranial nerve IX and X palsies who presented with severe dysphagia. After a mild head injury, the patient complained of difficult swallowing. Physical examination revealed normal tongue motion and no uvular deviation. Cervical X-ray findings were negative, but a brain computed tomography revealed a skull fracture involving bilateral jugular foramen. Laryngoscopy indicated bilateral vocal cord palsy. In a videofluoroscopic swallowing study, food residue remained in the vallecula and pyriform sinus, and there was reduced motion of the pharynx and larynx. Electromyography confirmed bilateral superior and recurrent laryngeal neuropathy. PMID:26949684

  12. Bilateral thalamic infarcts due to occlusion of the Artery of Percheron and discussion of the differential diagnosis of bilateral thalamic lesions.

    The Artery of Percheron is a rare vascular variant in which a single dominant thalamoperforating artery arises from one P1 segment and bifurcates to supply both paramedian thalami. Occlusion of this uncommon vessel results in a characteristic pattern of bilateral paramedian thalamic infarcts with or without mesencephalic infarctions. We report a case of a 31-year-old man with acute bilateral thalamic infarcts and a truncated Artery of Percheron demonstrated on magnetic resonance angiography (MRA). Occlusion of the vessel was presumably due to embolism from a patent foramen ovale that was subsequently closed. The case presentation is followed by a discussion of bilateral paramedian thalamic infarcts including the causes and clinical presentation. The differential diagnosis of vascular and nonvascular etiologies of bilateral thalamic lesions is also discussed. PMID:24421943

    Aural rehabilitation is a critical and often neglected aspect of a hearing-impaired patient's total rehabilitation. This case description illustrates the need for implementation of aural rehabilitation services. A 59-year-old woman exhibited bilateral profound sensorineural hearing loss following the onset of encephalitis herpes simplex. Auditory amplification attempts were unsuccessful. Aural rehabilitation was initiated immediately, and she was seen for lipreading and vibrotactile stimulation training. Goals progressed from identification of single words within a category to phonemic recognition. Vibrotactile stimulation was used to facilitate environmental awareness. Therapy goals reflected the patient's increased motivation to communicate within her environment. This patient's communicative status is viewed on a continuum: from success in individual treatment goals, extending to successful communication within the structure of the entire rehabilitation setting, and finally to functional communication within her home environment.

    A middle aged African-American woman with a stable history of carnitine palmitoyl transferase II (CPT II) deficiency presented with myalgias for 1 week. Physical examination and laboratory findings were consistent with severe sepsis secondary to pyelonephritis leading to rhabdomyolysis. Subsequent CT of the abdomen revealed bilateral supernumerary kidneys with non-obstructive calculi within the supernumerary kidneys. Abnormal ureteral development of the supernumerary kidneys likely led to an increased risk for urinary tract infections (UTIs) and renal calculi resulting in pyelonephritis. The stress of this infection overwhelmed the muscle CPT II enzyme load, putting her in a state of rhabdomyolysis. In addition to fluids and antibiotics, she was provided a diet rich in carbohydrates and low in fats so as to limit long-chain fatty acid oxidation. Supernumerary nephrectomy was not considered during this admission. During follow-up, she developed obstructive ureteral calculi requiring placement of a right-sided ureteral stent. PMID:24692375

    Introduction: Symptomatic adrenal adenoma usually presents with systemic symptoms. Depending on the function of the adenoma, the patient can present with pheochromocytoma-like symptoms; primary hyperaldosteronism and Cushing syndrome (weight gain, weakness, depression, and bruising). Case report: A 41 year-old lady presented with multiple metatarsal and phalangeal fractures of the both feet without significant injury. DEXA scan showed evidence of osteoporosis. Investigations showed that the picture was compatible with adrenal Cushing syndrome. Computed tomogram showed bilateral adrenal adenoma. Adrenal cortex scintigraphy with NP-59 scan showed hyperfunctioning right adrenal adenoma. Laproscopic R adrenalectomy was performed and histological study confirmed adrenal cortical adenoma with adjacent cortical atrophy suggestive of a functioning adenoma. Post-operatively, she was put on hydrocortisone replacement and recovered well. Conclusion: Adrenal adenoma can present with insufficiency fractures of the feet. PMID:27299107

    We report a case of a 75-year-old woman presenting a hitherto undescribed condition of bilateral second carpal row duplication. She was diagnosed in childhood with both Marfan and Ehlers-Danlos syndromes, with no clear evidence and no further medical follow-up. She presented throughout her life with various articular symptoms, which appeared to be compatible with a diagnosis of multiple epiphyseal dysplasia, and underwent several surgical procedures on her knees and hips. Most recently, she was reporting pain at the base of the fifth metacarpal bone of the left hand. X-ray images and computed tomography (CT) were obtained for exploration and showed a total second row duplication in both carpi, with a total number of 18 carpal bones in each wrist. PMID:26649258

    Spontaneous bacterial empyema (SBEM), a rare infectious complication among liver cirrhosis patients, is characterized by infection in the presence of pleural effusion without evidence of pre-existing pneumonia. The prevalence of SBEM in cirrhotic patients with hydrothorax is about 13%. However, it has previously not been reported in medical literature in patients with nephrotic syndrome. The most common microorganism identified is Escherichia coli, followed by Streptococcus species, Enterococcus species, Klebsiella pneumoniae, and Pseudomonas stutzeri. We present a patient with a history of nephrotic syndrome caused by membranous nephropathy, who received steroids and cyclophosphamide. He developed bilateral SBEM due to Aeromonas hydrophila and E. coli, which were isolated from the left- and right-side pleural fluid, respectively. The detailed clinical course, treatment, and outcome are described. PMID:16457891

  18. Impaired threat prioritisation after selective bilateral amygdala lesions

    The amygdala is proposed to process threat-related information in non-human animals. In humans, empirical evidence from lesion studies has provided the strongest evidence for a role in emotional face recognition and social judgement. Here we use a face-in-the-crowd (FITC) task which in healthy control individuals reveals prioritised threat processing, evident in faster serial search for angry compared to happy target faces. We investigate AM and BG, two individuals with bilateral amygdala lesions due to Urbach–Wiethe syndrome, and 16 control individuals. In lesion patients we show a reversal of a threat detection advantage indicating a profound impairment in prioritising threat information. This is the first direct demonstration that human amygdala lesions impair prioritisation of threatening faces, providing evidence that this structure has a causal role in responding to imminent danger.

    Simultaneous fractures of the femoral neck and shaft are not common injuries, though they cannot be considered rare. Herein, we report our experience with a patient with bilateral occurance of this injury. Up to the best of our knowkedge this is the first case reported in literature in which correct diagnosis was made initially. Both femurs were fixed using broad 4.5 mm dynamic compression plate and both necks were fixed using 6.5 mm cannulated screws. Femur fixation on one side was converted to retrograde nailing because of plate failure. Both neck fractures healed uneventfully. In spite of rarity of concomitant fractures of femoral neck and shaft, this injury must be approached carefully demanding especial attention and careful device selection. PMID:25692158

    Tarsometatarsal (Lisfranc) joint injuries are rare but potentially devastating conditions requiring anatomical reduction and internal fixation or arthrodesis. We describe an unusual mechanism involving forced eversion and dorsiflexion on both fully supinated feet resulting in bilateral tarsometatarsal joint injury. The injury pattern involved incongruity between the medial and middle columns extending between the cuneiform bones with associated fracture of the cuboid on the right and the cuboid, os calcis and talus on the left. Operative fixation is discussed and the clinical outcome was good at 4 years post-operatively. We believe this introduces an additional and potentially serious mechanism of injury and pattern of ligamentous and osseous disruption into the pantheon of injuries classed as Lisfranc, which surgeons should be aware of. Furthermore, we recommend attention to the mechanism of injury in consideration with classification to aid in operative reduction and fixation. PMID:25510168
