    A 57-year-old woman suffered rapid destruction of both hip joints over a 10 months period. At the first visit, her radiographs demonstrated slight joint space narrowing and acetabular cyst formation in both hips. Five months later, joint space narrowing had further progressed, and intra-articular injection of steroid was given in both hips. However, the hip pain gradually became worse. Five months later, both joint spaces had totally disappeared and both femoral heads had undergone massive collapse. At gross examination, both resected femoral heads showed extensive opaque yellow areas consistent with osteonecrosis. Microscopic examination of these areas revealed evidence of both extensive fracture and callus formation, as well as necrosis throughout, indicating that the osteonecrosis observed in this case was a secondary phenomenon superimposed on pre-existing osteoarthritis and subchondral fracture. There were many pseudogranulomatous lesions in the marrow space and necrotic area, where tiny fragments of bone and articular cartilage, surrounded by histiocytes and giant cells, were embedded, such as are typically seen in rapidly destructive arthrosis. No radiologic or morphologic evidence of primary osteonecrosis was noted. This case indicates that at least some cases of rapidly destructive arthritis are the result of subchondral fracture with superimposed secondary osteonecrosis. (orig.)

    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.

    Full Text Available Abstract Background Rapidly destructive arthrosis of the hip is a rare and incompletely understood disorder with scarce literature about variations in natural history within a population. Methods A series of cases from North Wales with rapid progressive joint destruction and extensive subchondral bone loss in the femoral head and acetabulum are presented. Radiographic findings mimicked those of other disorders such as septic arthritis, rheumatoid and seronegative arthritis, primary osteonecrosis with secondary osteoarthritis, or neuropathic osteoarthropathy, but none of the patients had clinical, pathologic, or laboratory evidence of these entities. Results Rapid progression of hip pain and disability was a consistent clinical feature. The average duration of symptoms was 1.4 years. Radiographs obtained at various intervals before surgery (average 14 months in 18 patients documented rapid hip destruction, involvement being unilateral in 13 cases. All patients underwent total hip arthroplasty, and osteoarthritis was confirmed at pathologic examination. Conclusion The authors postulate that these cases represent an uncommon subset of osteoarthritis and regular review, both clinically and radiologically, are required to assess speed of progression and prevent rapid loss of bone stock without the surgeon being aware. These cases are unsuitable for being placed on long waiting list due to technical difficulties in delayed surgery and compromised outcome following surgery.

    Complex injuries of the hand and wrist lead to severe loss of function. Complex trauma of the upper extremities may lead to severe disabilities and therefore meticulous reconstruction is of utmost importance to enable good functional outcome and to assure an adequate quality of life. We demonstrate the case of a patient who suffered from complex bilateral injuries at the wrist level including a subtotal amputation of the left hand and third degree open wrist destruction on the contralateral side. Due to the immediate bilateral operation including the unilateral use of an osteocutaneous free fibula flap, both hands could be salvaged in this case. Severe hand and wrist injuries also require intensive postoperative treatment including intensive physiotherapy, occupational therapy, pain therapy and psychological support to achieve a good functional result.

  5. Neural Correlates of Body and Face Perception Following Bilateral Destruction of the Primary Visual Cortices

    Full Text Available Non-conscious visual processing of different object categories was investigated in a rare patient with bilateral destruction of the visual cortex (V1 and clinical blindness over the entire visual field. Images of biological and non-biological object categories were presented consisting of human bodies, faces, butterflies, cars, and scrambles. Behaviorally, only the body shape induced higher perceptual sensitivity, as revealed by signal detection analysis. Passive exposure to bodies and faces activated amygdala and superior temporal sulcus. In addition, bodies also activated the extrastriate body area, insula, orbitofrontal cortex (OFC and cerebellum. The results show that following bilateral damage to the primary visual cortex and ensuing complete cortical blindness, the human visual system is able to process categorical properties of human body shapes. This residual vision may be based on V1-independent input to body-selective areas along the ventral stream, in concert with areas involved in the representation of bodily states, like insula, OFC and cerebellum.

    An elderly woman with osteoarthritis is presented with a unilateral, rapidly-destructive, erosive arthropathy. The etiology of this disorder is not clear, but patients presenting with the characteristic radiographic findings demonstrated in this patient, represent a definite subgroup of people with OA. Of great interest is the history of oral ingestion of indomethacin over a 6-month period.

    2013-03-01

    Hypertension secondary to hydronephrosis is not commonly reported in the medical literature. Tubuloglomerular feedback and the renin-angiotensin-aldosterone axis are thought to mediate this process. We describe a patient presenting with acute kidney injury and bilateral hydronephrosis secondary to pelvic malignancy in which peripheral venous renin and aldosterone were elevated. Her blood pressure improved rapidly following insertion of bilateral nephrostomies. The speed of resolution of hypertension following relief of obstruction suggests that humorally mediated vasoconstriction can play an important role in the mechanism by which hydronephrosis causes hypertension. We also discuss other causes of renal parenchymal compression that may lead to the development of hypertension.

    The pathophysiology of rapidly destructive osteoarthritis (OA) of the hip is unknown. This study documented cases of inversion of the acetabular labrum, which has clinicoradiologic features similar to those of initial-stage rapidly destructive hip OA. Our study was based on a prospective review of data for 9 patients with rapidly destructive hip OA. Intraoperative findings showed that the anterosuperior portion of the acetabular labrum had inverted into the articular space, along with many fragments of articular cartilage, in all patients. Subchondral insufficiency fractures of the femoral heads were seen just under the inverted labra in 8 of the 9 patients. Inversion of the acetabular labrum may be involved in rapid joint-space narrowing and subchondral insufficiency fracture in rapidly destructive hip OA.

    A 37-year-old female had been treated with corticosteroids for systemic lupus erythematosus clinically diagnosed at age 10. She suddenly had right hip pain without any antecedent trauma. Four months after the onset of pain, she visited her primary care physician. On magnetic resonance imaging, joint space narrowing at the weight-bearing area was already seen with bone marrow edematous lesions in both the femoral head and acetabulum. She was treated non-operatively; however, her pain continued to worsen in severity. Thirteen months after the onset of pain, she was referred to our hospital. A plain radiograph showed subluxation of the collapsed femoral head accompanied by destruction of the acetabular rim. Because of her severe intractable pain, she underwent total hip arthroplasty 1 month after her first visit. Histological examination of the resected femoral head revealed pseudogranulomatous lesions along with prominent callus formation, suggesting rapid destruction of the femoral head.

    Dentin moisture content is important in adhesive bonding and structural strength research. However, there is no rapid method available to assess dentin moisture without sample destruction. This study examined the use of a digital grain moisture meter to measure root dentin moisture in vitro. Extracted mandibular single rooted teeth were sectioned at the CEJ. The moisture of the root dentin was measured at six measuring modes for different grains and repeated five times. Dentin weight changes before and after drying were measured to obtain control values. The control values were compared with machine readings. In conclusion, (1) Each non-destructive measurement took less than 30 seconds. (2) 24 hours storage at 37°C and 100 % humidity did not restore dentin moisture. (3) Five grain modes had a high validity, and could be used for dentin moisture measurements. PMID:19157921

    Full Text Available We describe a 50-year-old Japanese patient with dermatofibrosarcoma protuberans (DFSP rapidly growing after bilateral adrenalectomy for Cushing’s syndrome that reduced the serum level of cortisol from 17.1 to 0.8 mg/dl. It is known that glucocorticoids decrease the transcriptions of the COL1A1 gene and the PDGFB gene, which is under the direct control of the COL1A1 gene in most DFSP. Therefore, the hypersecretion of glucocorticoids in Cushing’s syndrome might suppress the development of DFSP. To the best of our knowledge, this is the first case of rapid growth of DFSP that may be associated with bilateral adrenalectomy for Cushing’s syndrome.

    Bilateral spontaneous quadriceps rupture is an uncommon injury that is usually seen in association with multiple medical conditions and is frequently misdiagnosed. It is rarely seen in healthy, active individuals. This article presents a case of bilateral simultaneous and spontaneous rupture of the quadriceps tendon in a healthy, athletic, active and highly motivated patient with rapid recovery from injury and return to full sport activity within a relatively short period of time. A 65-year-old healthy man felt both knees give way while walking down stairs at home and collapsed, unable to bear weight. He was fit and well, not on any medications and basic laboratory screening was within normal limits. He was an active sportsman, horse rider, swimmer, and long-distance cyclist, and had completed a half marathon 1 month before his injury. He was diagnosed with bilateral quadriceps tendon ruptures. An ultrasound of both knees confirmed the diagnosis of full-thickness rupture. Surgical repair of both quadriceps tendons was performed 3 days after the injury. Bilateral locking brace in 10 degrees of flexion was used to immobilize both knees and protect the repair for 6 weeks. The patient remained nonweight bearing for 2 weeks, then gradual weight bearing was commenced, with full weight bearing at 6 weeks. Intensive isometric quadriceps exercises were started on the second postoperative day. Immobilization of both knees was maintained for 6 weeks, after which full active range of motion (ROM) was initiated. At 16 weeks after the injury he had bilateral ROM from 0 degrees to 120 degrees flexion, with no extension lag. He was horse riding, playing golf, swimming, and walking distances up to 2 miles at that time.

  13. Rapid Changes in Cortical and Subcortical Brain Regions after Early Bilateral Enucleation in the Mouse.

    Directory of Open Access Journals (Sweden)

    Olga O Kozanian

    Full Text Available Functional sensory and motor areas in the developing mammalian neocortex are formed through a complex interaction of cortically intrinsic mechanisms, such as gene expression, and cortically extrinsic mechanisms such as those mediated by thalamic input from the senses. Both intrinsic and extrinsic mechanisms are believed to be involved in cortical patterning and the establishment of areal boundaries in early development; however, the nature of the interaction between intrinsic and extrinsic processes is not well understood. In a previous study, we used a perinatal bilateral enucleation mouse model to test some aspects of this interaction by reweighting sensory input to the developing cortex. Visual deprivation at birth resulted in a shift of intraneocortical connections (INCs that aligned with ectopic ephrin A5 expression in the same location ten days later at postnatal day (P 10. A prevailing question remained: Does visual deprivation first induce a change in gene expression, followed by a shift in INCs, or vice versa? In the present study, we address this question by investigating the neuroanatomy and patterns of gene expression in post-natal day (P 1 and 4 mice following bilateral enucleation at birth. Our results demonstrate a rapid reduction in dorsal lateral geniculate nucleus (dLGN size and ephrin A5 gene expression 24-hours post-enucleation, with more profound effects apparent at P4. The reduced nuclear size and diminished gene expression mirrors subtle changes in ephrin A5 expression evident in P1 and P4 enucleated neocortex, 11 and 8 days prior to natural eye opening, respectively. Somatosensory and visual INCs were indistinguishable between P1 and P4 mice bilaterally enucleated at birth, indicating that perinatal bilateral enucleation initiates a rapid change in gene expression (within one day followed by an alteration of sensory INCs later on (second postnatal week. With these results, we gain a deeper understanding of how gene

    We demonstrate a smartphone based spectrometer design that is standalone and supported on a wireless platform. The device is inherently low-cost and the power consumption is minimal making it portable to carry out a range of studies in the field. All essential components of the device like the light source, spectrometer, filters, microcontroller and wireless circuits have been assembled in a housing of dimensions 88 mm × 37 mm × 22 mm and the entire device weighs 48 g. The resolution of the spectrometer is 15 nm, delivering accurate and repeatable measurements. The device has a dedicated app interface on the smartphone to communicate, receive, plot and analyze spectral data. The performance of the smartphone spectrometer is comparable to existing bench-top spectrometers in terms of stability and wavelength resolution. Validations of the device were carried out by demonstrating non-destructive ripeness testing in fruit samples. Ultra-Violet (UV) fluorescence from Chlorophyll present in the skin was measured across various apple varieties during the ripening process and correlated with destructive firmness tests. A satisfactory agreement was observed between ripeness and fluorescence signals. This demonstration is a step towards possible consumer, bio-sensing and diagnostic applications that can be carried out in a rapid manner.

    Staple foods, including cereals, legumes, and root/tuber crops, dominate the daily diet of humans by providing valuable proteins, starch, oils, minerals, and vitamins. Quality evaluation of staple foods is primarily carried out on sensory (e.g. external defect, color), adulteration (e.g. species, origin), chemical (e.g. starch, proteins), mycotoxin (e.g. Fusarium toxin, aflatoxin), parasitic infection (e.g. weevil, beetle), and internal physiological (e.g. hollow heart, black heart) aspects. Conventional methods for the quality assessment of staple foods are always laborious, destructive, and time-consuming. Requirements for online monitoring of staple foods have been proposed to encourage the development of rapid, reagentless, and noninvasive techniques. Spectroscopic techniques, such as visible-infrared spectroscopy, Raman spectroscopy, nuclear magnetic resonance spectroscopy, and spectral imaging, have been introduced as promising analytical tools and applied for the quality evaluation of staple foods. This review summarizes the recent applications and progress of such spectroscopic techniques in determining various qualities of staple foods. Besides, challenges and future trends of these spectroscopic techniques are also presented.

    In this paper, litchi freshness rapid non-destructive evaluating method using electronic nose (e-nose) and non-linear stochastic resonance (SR) was proposed. EN responses to litchi samples were continuously detected for 6 d Principal component analysis (PCA) and non-linear stochastic resonance (SR) methods were utilized to analyze EN detection data. PCA method could not totally discriminate litchi samples, while SR signal-to-noise ratio (SNR) eigen spectrum successfully discriminated all litchi samples. Litchi freshness predictive model developed using SNR eigen values shows high predictive accuracy with regression coefficients R(2) = 0 .99396.

    Meat is an important food item in human diet. Its production and consumption has greatly increased in the last decades with the development of economies and improvement of peoples' living standards. However, most of the traditional methods for evaluation of meat quality are time-consuming, laborious, inconsistent and destructive to samples, which make them not appropriate for a fast-paced production and processing environment. Development of innovative and non-destructive optical sensing techniques to facilitate simple, fast, and accurate evaluation of quality are attracting increasing attention in the food industry. Hyperspectral imaging is one of the promising techniques. It integrates the combined merits of imaging and spectroscopic techniques. This paper provides a comprehensive review on recent advances in evaluation of the important quality attributes of meat including color, marbling, tenderness, pH, water holding capacity, and also chemical composition attributes such as moisture content, protein content and fat content in pork, beef and lamb. In addition, the future potential applications and trends of hyperspectral imaging are also discussed in this paper.

  20. Rapid cytotoxicity of antimicrobial peptide tempoprin-1CEa in breast cancer cells through membrane destruction and intracellular calcium mechanism.

    Che Wang

    Full Text Available Temporin-1CEa is an antimicrobial peptide isolated from the skin secretions of the Chinese brown frog (Rana chensinensis. We have previously reported the rapid and broad-spectrum anticancer activity of temporin-1CEa in vitro. However, the detailed mechanisms for temporin-1CEa-induced cancer cell death are still weakly understood. In the present study, the mechanisms of temporin-1CEa-induced rapid cytotoxicity on two human breast cancer cell lines, MDA-MB-231 and MCF-7, were investigated. The MTT assay and the LDH leakage assay indicated that one-hour of incubation with temporin-1CEa led to cytotoxicity in a dose-dependent manner. The morphological observation using electronic microscopes suggested that one-hour exposure of temporin-1CEa resulted in profound morphological changes in both MDA-MB-231 and MCF-7 cells. The membrane-disrupting property of temporin-1CEa was further characterized by induction of cell-surface exposure of phosphatidylserine, elevation of plasma membrane permeability and rapid depolarization of transmembrane potential. Moreover, temporin-1CEa evoked intracellular calcium ion and reactive oxygen species (ROS elevations as well as collapse of mitochondrial membrane potential (Δφm. In summary, the present study indicates that temporin-1CEa triggers rapid cell death in breast cancer cells. This rapid cytotoxic activity might be mediated by both membrane destruction and intracellular calcium mechanism.

    The power and simplicity of visual colony counting have made it the mainstay of microbiological analysis for more than 130 years. A disadvantage of the method is the long time required to generate visible colonies from cells in a sample. New rapid testing technologies generally have failed to maintain one or more of the major advantages of culture-based methods. We present a new technology and platform that uses digital imaging of cellular autofluorescence to detect and enumerate growing microcolonies many generations before they become visible to the eye. The data presented demonstrate that the method preserves the viability of the microcolonies it detects, thus enabling generation of pure cultures for microbial identification. While visual colony counting detects Escherichia coli colonies containing about 5x10(6) cells, the new imaging method detects E. coli microcolonies when they contain about 120 cells and microcolonies of the yeast Candida albicans when they contain only about 12 cells. We demonstrate that digital imaging of microcolony autofluorescence detects a broad spectrum of prokaryotic and eukaryotic microbes and present a model for predicting the time to detection for individual strains. Results from the analysis of environmental samples from pharmaceutical manufacturing plants containing a mixture of unidentified microbes demonstrate the method's improved test turnaround times. This work demonstrates a new technology and automated platform that substantially shortens test times while maintaining key advantages of the current methods.

    2013-01-01

    Full Text Available Introduction. Rapidly vanishing lung pseudotumor (phantom tumor refers to the transient well-demarcated accumulation of pleural fluid in the interlobar pulmonary fissures. Most frequently their appearance is associated with congestive heart failure, but also other disorders like hypoalbuminemia, renal insufficiency or pleuritis. Its rapid disappearance in response to the treatment of the underlying disorder is a classical feature of this clinical entity. Case report. A 47-yearold woman, chronic smoker with symptoms of shortness of breath, orthopnea, chills, cough, weakness and the temperature of 39.2°C was admitted to our hospital. A posteroanterior chest X-ray revealed cardiomegaly with the cardiothoracic ratio of > 0.5, blunting of both costophrenic angles and an adjacent 6 x 5 cm well-defined, rounded opacity in the right interlobar fissure. Transthoracic 2-dimensional echocardiography demonstrated left ventricular hyperthrophy with a systolic ejection fraction of 25% and moderate mitral regurgitation. The patient’s symptoms resolved rapidly after diuresis, and repeated chest X-ray four days later showed that the right lung opacity and pleural effusions had vanished. Conclusion. The presented case underlines the importance of the possibility of vanishing lung tumor in patients with left ventricular failure and a sharp oval lung mass on the chest X-ray. This is the way to avoid incorrect interpretation of this finding causing additional, unnecessary, costly or invasive imaging, interventions and drugs.

  4. Proposal of a New Method for Measuring Förster Resonance Energy Transfer (FRET Rapidly, Quantitatively and Non-Destructively

    Directory of Open Access Journals (Sweden)

    Paul Johannes Helm

    2012-09-01

    Full Text Available The process of radiationless energy transfer from a chromophore in an excited electronic state (the “donor” to another chromophore (an “acceptor”, in which the energy released by the donor effects an electronic transition, is known as “Förster Resonance Energy Transfer” (FRET. The rate of energy transfer is dependent on the sixth power of the distance between donor and acceptor. Determining FRET efficiencies is tantamount to measuring distances between molecules. A new method is proposed for determining FRET efficiencies rapidly, quantitatively, and non-destructively on ensembles containing donor acceptor pairs: at wavelengths suitable for mutually exclusive excitations of donors and acceptors, two laser beams are intensity-modulated in rectangular patterns at duty cycle ½ and frequencies ƒ1 and ƒ2 by electro-optic modulators. In an ensemble exposed to these laser beams, the donor excitation is modulated at ƒ1, and the acceptor excitation, and therefore the degree of saturation of the excited electronic state of the acceptors, is modulated at ƒ2. Since the ensemble contains donor acceptor pairs engaged in FRET, the released donor fluorescence is modulated not only at ƒ1 but also at the beat frequency Δƒ: = |ƒ1 − ƒ2|. The depth of the latter modulation, detectable via a lock-in amplifier, quantitatively indicates the FRET efficiency.

    Bilateral oophorectomy leads to reduced bone mineral density (BMD), and reduced BMD is associated with increased marrow fat and reduced marrow perfusion. Purpose of this study was to investigate how soon these changes occur following surgical oophorectomy. Six patients who underwent hysterectomy and bilateral salpingo-oophorectomy were studied. At baseline, mean patient age was 49.5 years (range: 45-54 years). Third lumbar vertebral body BMD measurement using quantitative CT, marrow fat fraction (FF) using MR spectroscopy and marrow perfusion using dynamic contrast enhanced MRI were conducted immediately prior to surgery and at 3, 9, and 21 months after surgery. Reduced BMD, increased marrow FF, and reduced marrow perfusion occurred synchronously post-oophorectomy. There was a sharp decrease of 12.5 +/- 7.2% in BMD (n = 6), a sharp increase of 92.2 +/- 46.3% (n = 6) in FF, a sharp decrease of 23.6 +/- 3.9% in maximum contrast enhancement (n = 5), and of 45.4 +/- 7.7% for enhancement slope (n = 5) during the initial 3 months post surgery. BMD and marrow perfusion continued to decrease, and marrow FF continued to increase at a slower rate during the following 18 months. Friedman test showed a significant trend for these changes (p < 0.05). Bilateral oophorectomy leads to a rapid decrease in lumbar BMD, an increase in marrow fat content, and a decrease in marrow blood perfusion.

    Body fluid traces recovered at crime scenes are among the most important types of evidence to forensic investigators. They contain valuable DNA evidence which can identify a suspect or victim as well as exonerate an innocent individual. The first step of identifying a particular body fluid is highly important since the nature of the fluid is itself very informative to the investigation, and the destructive nature of a screening test must be considered when only a small amount of material is available. The ability to characterize an unknown stain at the scene of the crime without having to wait for results from a laboratory is another very critical step in the development of forensic body fluid analysis. Driven by the importance for forensic applications, body fluid identification methods have been extensively developed in recent years. The systematic analysis of these new developments is vital for forensic investigators to be continuously educated on possible superior techniques. Significant advances in laser technology and the development of novel light detectors have dramatically improved spectroscopic methods for molecular characterization over the last decade. The application of this novel biospectroscopy for forensic purposes opens new and exciting opportunities for the development of on-field, non-destructive, confirmatory methods for body fluid identification at a crime scene. In addition, the biospectroscopy methods are universally applicable to all body fluids unlike the majority of current techniques which are valid for individual fluids only. This article analyzes the current methods being used to identify body fluid stains including blood, semen, saliva, vaginal fluid, urine, and sweat, and also focuses on new techniques that have been developed in the last 5-6 years. In addition, the potential of new biospectroscopic techniques based on Raman and fluorescence spectroscopy is evaluated for rapid, confirmatory, non-destructive identification of a body

    Our purpose in this case report is to present an orthodontic treatment obtained and the results achieved in 17-year-old white female patient with Angle Class II malocclusion and bilateral posterior crossbite. Patient was treated with bonded acrylic Hyrax appliance and surgically assisted rapid maxillary expansion (SARME). The multiloop system 0.16 TMA (ß titanium) arch wire was used in the alignment phase and on purpose to prohibit bite opening and optimize threedimensional movement control. After treatment bonded lingual retainers were placed in between maxillary central incisors and in mandible canine-to-canine. A functional removable Klammt appliance was used for retention. The 3D Laser Scanner Roland LPX-250 was used in order to obtain digital dental casts. Evaluation of the treatment results was measured on these models and using finite element scaling analysis (FESA). An Angle Class I relationship was obtained after 2½ years of treatment, function and facial aesthetics were improved. The shape of the palate changed significant in the width direction, not significantly in length and high direction. The greatest expansion of palate was found in the region between the palatal cusps of the first molars 26.6%, followed by first 21.9% and second premolars 16.5%. SARME in adult patients with bilateral cross bite and maxillary deficiency lead to satisfactory results. The 3D laser scanned models and their measurements, using advanced software's are successfully used for precise studies.

    To compare simultaneous integrated boost plans for intensity-modulated proton therapy (IMPT), helical tomotherapy (HT), and RapidArc therapy (RA) for patients with head and neck cancer. A total of 20 patients with squamous cell carcinoma of the head and neck received definitive chemoradiation with bilateral (n = 14) or unilateral (n = 6) neck irradiation and were planned using IMPT, HT, and RA with 54.4, 60.8, and 70.4 GyE/Gy in 32 fractions. Dose distributions, coverage, conformity, homogeneity to planning target volumes (PTV)s and sparing of organs at risk and normal tissue were compared. All unilateral and bilateral plans showed excellent PTV coverage and acceptable dose conformity. For unilateral treatment, IMPT delivered substantially lower mean doses to contralateral salivary glands (< 0.001-1.1 Gy) than both rotational techniques did (parotid gland: 6-10 Gy; submandibular gland: 15-20 Gy). Regarding the sparing of classical organs at risk for bilateral treatment, IMPT and HT were similarly excellent and RA was satisfactory. For unilateral neck irradiation, IMPT may minimize the dry mouth risk in this subgroup but showed no advantage over HT for bilateral neck treatment regarding classical organ-at-risk sparing. All methods satisfied modern standards regarding toxicity and excellent target coverage for unilateral and bilateral treatment of head and neck cancer at the planning level. (orig.)

    In the present study, for the first time, NIR spectroscopy coupled with PLS regression as a rapid and alternative method was developed to quantify the amount of Keto-β-Boswellic Acid (KBA) in different plant parts of Boswellia sacra and the resin exudates of the trunk. NIR spectroscopy was used for the measurement of KBA standards and B. sacra samples in absorption mode in the wavelength range from 700-2500 nm. PLS regression model was built from the obtained spectral data using 70% of KBA standards (training set) in the range from 0.1 ppm to 100 ppm. The PLS regression model obtained was having R-square value of 98% with 0.99 corelationship value and having good prediction with RMSEP value 3.2 and correlation of 0.99. It was then used to quantify the amount of KBA in the samples of B. sacra. The results indicated that the MeOH extract of resin has the highest concentration of KBA (0.6%) followed by essential oil (0.1%). However, no KBA was found in the aqueous extract. The MeOH extract of the resin was subjected to column chromatography to get various sub-fractions at different polarity of organic solvents. The sub-fraction at 4% MeOH/CHCl3 (4.1% of KBA) was found to contain the highest percentage of KBA followed by another sub-fraction at 2% MeOH/CHCl3 (2.2% of KBA). The present results also indicated that KBA is only present in the gum-resin of the trunk and not in all parts of the plant. These results were further confirmed through HPLC analysis and therefore it is concluded that NIRS coupled with PLS regression is a rapid and alternate method for quantification of KBA in Boswellia sacra. It is non-destructive, rapid, sensitive and uses simple methods of sample preparation.

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

    The objective of this study was to evaluate the potential of a new handheld ultra-compact near infrared (NIR) spectrometer, based on the linear-variable filter (LVF) technology for rapid and non-destructive quality control analysis of the 'Tommy Atkins' mango. Multivariate calibration models were built using the Partial Least Squares (PLS) regression method to determine soluble solids (SS), dry matter (DM), titratable acidity (TA) and pulp firmness (PF). Different spectral pre-processing techniques were tested. Coefficient of determination and root mean square errors of prediction (RMSEP) values were, respectively: 0.92 and 0.55°Brix for SS, 0.67 and 0.51% for DM, 0.50 and 0.17% citric acid for TA, 0.72 and 12.2N for PF. The predictive models allowed monitoring physico-chemical changes in each fruit during ripening. The results show the feasibility of using the new NIR handheld spectrometer to determine quality parameters in the 'Tommy Atkins' mango. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Many existing methods to monitor the corrosion of concrete in sewers are either very slow or destructive measurements. To overcome these limitations, a rapid, non-invasive methodology was developed to monitor the sulfide-induced corrosion process on concrete through the measurement of the H2S uptake rates of concrete at various corrosion stages. The H2S uptake rate for a concrete coupon was determined by measuring the gaseous H2S concentrations over time in a temperature- and humidity-controlled gas-tight reactor. The reliability of this method was evaluated by carrying out repeated tests on different concrete coupons previously exposed to 50 ppm of H2S, at 30 °C and 100% relative humidity for over 32 months. The H2S uptake measurements showed good reproducibility. It was also shown that a severely corroded coupon exhibited higher sulfide uptake rates than a less corroded coupon. This could be explained by the corrosion layer in the more corroded coupon having a higher biological sulfide oxidation activity than the less corroded coupon. Additionally, temperature changes had a stronger effect on the uptake rate of the heavily corroded coupon compared to the less corroded coupon. A corrosion rate of 8.9 ± 0.5 mm/year, estimated from the H2S uptake results, agreed well with the corrosion rate observed in real sewers under similar conditions. The method could be applied to investigate important factors affecting sulfide-induced concrete corrosion, particularly temperature, fluctuating gaseous H2S concentrations, oxygen concentrations, surface pH and relative humidity.

    The performance of a multispectral imaging system has been evaluated in monitoring aerobically packaged beef filet spoilage at different storage temperatures (0, 4, 8, 12, and 16°C). Spectral data in the visible and short wave near infrared area (405-970nm) were collected from the surface of meat samples and correlated with microbiological data (log counts), for total viable counts (TVCs), Pseudomonas spp., and Brochothrix thermosphacta. Qualitative analysis (PLS-DA) was employed for the discrimination of meat samples in three microbiological quality classes based on the values of total viable counts, namely Class 1 (TVC7.0log10CFU/g). Furthermore, PLS regression models were developed to provide quantitative estimations of microbial counts during meat storage. In both cases model validation was implemented with independent experiments at intermediate storage temperatures (2 and 10°C) using different batches of meat. Results demonstrated good performance in classifying meat samples with overall correct classification rate for the three quality classes ranging from 91.8% to 80.0% for model calibration and validation, respectively. For quantitative estimation, the calculated regression coefficients between observed and estimated counts ranged within 0.90-0.93 and 0.78-0.86 for model development and validation, respectively, depending on the microorganism. Moreover, the calculated average deviation between observations and estimations was 11.6%, 13.6%, and 16.7% for Pseudomonas spp., B. thermosphacta, and TVC, respectively. The results indicated that multispectral vision technology has significant potential as a rapid and non-destructive technique in assessing the microbiological quality of beef fillets.

    The release of Wolbachia infected mosquitoes is likely to form a key component of disease control strategies in the near future. We investigated the potential of using near-infrared spectroscopy (NIRS) to simultaneously detect and identify two strains of Wolbachia pipientis (wMelPop and wMel) in male and female laboratory-reared Aedes aegypti mosquitoes. Our aim is to find faster, cheaper alternatives for monitoring those releases than the molecular diagnostic techniques that are currently in use. Our findings indicate that NIRS can differentiate females and males infected with wMelPop from uninfected wild type samples with an accuracy of 96% (N = 299) and 87.5% (N = 377), respectively. Similarly, females and males infected with wMel were differentiated from uninfected wild type samples with accuracies of 92% (N = 352) and 89% (N = 444). NIRS could differentiate wMelPop and wMel transinfected females with an accuracy of 96.6% (N = 442) and males with an accuracy of 84.5% (N = 443). This non-destructive technique is faster than the standard polymerase chain reaction diagnostic techniques. After the purchase of a NIRS spectrometer, the technique requires little sample processing and does not consume any reagents. PMID:27362709

    Bilateral oophorectomy leads to reduced bone mineral density (BMD), and reduced BMD is associated with increased marrow fat and reduced marrow perfusion. Purpose of this study was to investigate how soon these changes occur following surgical oophorectomy. Six patients who underwent hysterectomy and bilateral salpingo-oophorectomy were studied. At baseline, mean patient age was 49.5 years (range: 45-54 years). Third lumbar vertebral body BMD measurement using quantitative CT, marrow fat fraction (FF) using MR spectroscopy and marrow perfusion using dynamic contrast enhanced MRI were conducted immediately prior to surgery and at 3, 9, and 21 months after surgery. Reduced BMD, increased marrow FF, and reduced marrow perfusion occurred synchronously post-oophorectomy. There was a sharp decrease of 12.5 ± 7.2% in BMD (n = 6), a sharp increase of 92.2 ± 46.3% (n = 6) in FF, a sharp decrease of 23.6 ± 3.9% in maximum contrast enhancement (n = 5), and of 45.4 ± 7.7% for enhancement slope (n = 5) during the initial 3 months post surgery. BMD and marrow perfusion continued to decrease, and marrow FF continued to increase at a slower rate during the following 18 months. Friedman test showed a significant trend for these changes (p decrease in lumbar BMD, an increase in marrow fat content, and a decrease in marrow blood perfusion.

    A 38-year-old man with brittle, juvenile onset diabetes mellitus and bilateral severe dry eyes with recurrent corneal ulcers developed atypical band-shaped calcifications of both corneas during a 24-hour period. Serum calcium, phosphate, and carbon dioxide levels all were within normal limits. The patient was mildly uremic but was not in renal failure. When EDTA chelation failed to clear the deposits, partial keratectomies were performed in both eyes and the specimens were examined by light and electron microscopy, including energy dispersive x-ray analysis. Microscopic studies revealed an atypical calcific keratopathy which involved neither Bowman's layer nor the most superficial stromal lamellae. The deposits were confined to deeper lamellae in the anterior stroma and by electron microscopy were composed of extracellular crystalline aggregates. Energy dispersive x-ray analysis of these aggregates confirmed the presence of calcium and phosphate. Corneal dessication appeared to be a major contributing factor in the rapid formation of these deposits.

    2014-05-01

    Tephrostratigraphy has been considerably developed for 30 years, mainly in palaeo-environmental studies. In such studies, distal tephra layers are important chronological markers, but they are also tools to establish or specify record of past eruptions of a volcanic field. Nowadays, development of effective rapid methods to detect tephra layers in sedimentary records of various compositions is a challenge. Many classic methods for detection of tephra layers, like regular sampling or magnetic susceptibility measurements, have shown their limits. Regular sampling takes a long time, and finding tephra layers remains uncertain. Moreover, magnetic susceptibility maesurements, although it is a non-destructive method, is ineffective when tephra layers are made of volcanic glass shards with differentiated magma composition. X-ray fluorescence (XRF) is also a non-destructive method but it takes a very long time to analyze a core with sufficient high resolution, and measurements only concern the surface of the sediment. We propose a new method allows detection of tephra layers with, for the first time, a 3D resolution: the Computed Tomography Scan (CT- Scan). This method, regularly used in medicine, allows there to obtain pictures of materials density on 3D with inframillimetric measurement ranges. Then, it is possible to detect tephras, cryptotephras (invisible by naked eye), reworked tephra layers even when tephra layers don't outcrop at the surface of the sediment (and are therefore undetectable by usual methods like XRF and magnetic susceptibility). This method has been tried out on tephras sedimented in different types of sediments (silicated, carbonated and organic matter). Our results show that this method is very efficient for peaty environment. Used on coring carried out in Forez Mountains (French Massif Central), CT-Scan allows to detect more tephra layers than usual methods (XRF and magnetic susceptibility). Results presented here allow to build the first

    Full Text Available Destructiveness is among the fundamental discourse categories that play a significant role in the organization of communicative interaction and define the pragmatics of discourse; its study helps to understand some mechanisms and principles of communication, identify strategies and tactics used by a destructive communicative personality. The relevance of this study is determined by the increasing aggressiveness in various types of discourse, and, accordingly, by the need to extend the knowledge of destructive behavior of a communicative personality. The study is based on the theory of discourse-analysis and theory of destructiveness (Z. Harris, T. van Dijk, A. Buss, E. Fromm, D. Ponton, K. Hacker, R. Wodak. N. Arutyunova, V. Karasik, M. Makarov, E. Sheigal et al. Developing the theory of destructiveness and relying on Erich Fromm’s research (1973, we specify the concept of “destructiveness” in relation to the political discourse and compare it with the related concept of aggressiveness. The paper analyses the category of destructiveness in modern US political discourse, using excerpts from the speeches of the candidates for presidency of 2016. Particular attention is paid to the dominant destructive intention - to harm the reputation of the opponent and reduce his political chances, as well as to the functions of verbal aggression: on the one hand - to discredit the opponent, bring accusations, on the other hand - to poison the audience mind against him/her and arouse the feeling of danger posed by a political opponent. The analysis of verbal and nonverbal means of destructiveness in the US political discourse is carried out. The article concludes that abusive remarks of politicians do not result from spontaneous emotional outburst, but from an elaborated destructive strategy where the agonistic nature of political discourse stipulates the use of instrumental aggression (Buss, 1971 for the sake of the conquest of power, lowering the

    Renal angiomyolipoma is a rare benign tumour, often associated with congenital diseases especially de Bourneville's tuberous sclerosis. Bilateral angiomyolipoma is exceptional. The authors report a case of bilateral renal angiomyolipoma in a 33-year-old patient presenting with haemorrhagic shock. In the light of this case and a review of the literature, the authors discuss the diagnostic and therapeutic aspects of this disease.

    2015-01-01

    Full Text Available Background: Acute bilateral extradural hematoma is a rare presentation of head trauma injury. In sporadic cases, they represent 0.5-10% of all extradural hematomas. However, higher mortality rates have been reported in previous series. Case Description: The authors described the case of a 28-year-old male presenting head injury, comatose, Glasgow Coma Scale of 6, anisocoric pupils without puppilary light reflex. Computed tomography showed asymmetric bilateral epidural hematomas, effacement of the lateral ventricles and sulci, midline shift and a bilateral skull fracture reaching the vertex. Surgical evacuation was performed with simultaneous hematoma drainage. Patient was discharged on the 29 th postoperative day with no neurological deficit. Conclusion: The correct approach on bilateral epidural hematomas depends on the volume, moment of diagnosis, and neurological deficit level. Simultaneous drainage of bilateral hematomas has been demonstrated to be an effective technique for it, which soon decreases the intracranial pressure and promotes an efficient resolution to the neurological damage.

  18. Compensation following bilateral vestibular damage

    Directory of Open Access Journals (Sweden)

    Bill J Yates

    2011-12-01

    Full Text Available 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 nonlabyrinthine 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.

    We study money creation and destruction in today’s monetary architecture and examine the impact of monetary policy and capital regulation in a general equilibrium setting. There are two types of money created and destructed: bank deposits, when banks grant loans to firms or to other banks and central bank money, when the central bank grants loans to private banks. We show that equilibria yield the first-best level of money creation and lending when prices are flexible, regardless of the monet...

    A succinct definition of the word bilateral is having two sides [1]. In robotics the term bilateral control is used to define the specific interaction of two systems by means of position and/or force. Bilateral systems are composed of two sides named master and slave side. The aim of such an arrangement is such that position command dictated by master side is followed by a slave side, and at the same time the force sensation of the remote environment experienced by slave is transferred to the...

    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.

    2013-03-01

    Mandibular metastasis of thyroid carcinoma is extremely rare. We present the case of a 46-year-old woman who had bilateral huge cheek masses that had grown rapidly over several years. Intra-oral mucosal tissue biopsy and imaging work-up including computed tomography scan and magnetic resonance imaging were performed and the initial diagnosis was presumed to be central giant cell granuloma. Incidentally detected thyroid lesions were studied with ultra-sonography guided fine needle aspiration and diagnosed as simple benign nodules. Due to continuous oral bleeding and the locally destructive feature of the lesions, we decided to excise the mass surgically. To avoid functional deficit, a stepwise approach was performed: Firstly, the larger left mass was excised and the mandible was reconstructed with a fibular free flap. The final pathologic diagnosis was follicular thyroid cancer. Postoperative I-131 thyroid scan and whole body positron-emissions-tomography were performed. Right side mass was revealed as a thyroid malignancy. Multiple bony metastases were detected. Since further radioactive iodine therapy was required, additional total thyroidectomy and right side mandibulectomy with fibular free flap reconstruction was performed. The patient also underwent high dose radioactive iodine therapy and palliative extra-beam radiotherapy for the metastatic lumbar lesion. Follicular thyroid carcinoma should be considered as a differential diagnosis for mandibular mass lesions.

    Full Text Available Diabetic osteoarthropathy is a rare cause of neuropathic joint disease of the knee; bilateral involvement is even more exceptional. Diagnosis is often made late due to its unspecific symptoms and appropriate surgical management still needs to be defined, due to lack of evidence because of the disease’s low incidence. We report the case of a forty-year-old woman with history of diabetes type I who developed bilateral destructive Charcot knee arthropathy. Bilateral total knee arthroplasty was performed in order to achieve maximal functional outcome. Follow-up was marked by bilateral tibial periprosthetic fractures treated by osteosynthesis with a satisfactory outcome. The diagnosis of Charcot arthropathy should always be in mind when dealing with atraumatic joint destruction in diabetic patients. Arthroplasty should be considered as an alternative to arthrodesis in bilateral involvement in young patients.

    2013-06-01

    Full Text Available Morgagni hernia is a rare congenital diaphragmatic hernia. It is seen rarely bilaterally. Patients are usually asymptomatic. Therefore, diagnosis may be delayed until adulthood. Significant morbidity can occur in case complications arise and diagnosis is delayed. The patient, a 74 year-old female, presented in this article, was admitted to the emergency department with abdominal pain, vomiting, and shortness of breath. The plain abdominal radiograph of the patient revealed bowel obstruction and suspicious appearence in favor of the diaphragmatic hernia on both sides of the sternum. Computed tomography revealed bilaterally incarcerated Morgagni hernia with strangulated omentum in the right side of the sternum and a part of colon in the left side of sternum. Incarcerated organs were withdrawn to peritoneal cavity and defects of hernia were sutured primarily on laparatomy. Because bilateral incarcerated Morgagni hernia can be seen rarely, this case was reported.

    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

    Emphysematous pyelonephritis (EPN) is a serious infectious disease that occurs more frequently in diabetic patients. Radiological studies are indispensable for distinguishing between the two types since each is associated with a markedly different prognosis. We present a case of bilateral EPN diagnosed as type I on the basis of computed tomography findings, differentiating it from type II EPN, taking into account the prognostic value of this distinction. Type I EPN is characterized by the destruction of the renal parenchyma, a mottled or linear gas pattern and the absence of renal and perirenal fluid collection. Type II EPN is characterized by a loculated or bubbly gas pattern, the existence of fluid collection and less marked renal destruction. Type I is more aggressive and is associated with high rate of mortality. (Author) 7 refs.

    Congenital absence of tibia is a rare anomaly. We report a case of bilateral tibial hemimelia born to phenotypically normal parents. The two amputated legs with tibial dysplasia obtained from a 3-year-old boy were studied by radiography and anatomical dissection. The radiological evaluation revealed a normal hip joint. The lower end of femur was normal without any bifurcation, shortening or bowing. Fibula was present on both legs and there was no sign of bowing or doubling. Both right and left tibiae were absent. In addition, on the right side, five tarsal bones, two metatarsals and the corresponding digital rays were absent. On the left side, three tarsal bones were absent. Dissection of the amputated segments showed the presence of extensor digitorum longus, peroneus tertius, peroneus longus and brevis, gastrocnemius, and soleus. Following bilateral knee disarticulation the patient was fitted with prosthesis and is doing well.

    The author reports the case of a well and fit patient who presented herself to the emergency department and was found to have bilateral emphysematous pyelonephritis. She was admitted to the intensive care where she was initially treated conservatively with antibiotics, percutaneous drainage and continuous renal replacement therapy, but her condition deteriorated. She underwent a left total nephrectomy and a partial right nephrectomy that resulted in remarkable improvement. The patient started passing urine spontaneously, so no haemofiltration was required. She was discharged home and her case was followed-up by an urologist and nephrologist. This case lays emphasis on thoroughly investigating and managing a patient with bilateral emphysematous pyelonephritis and, in relation to its management, on the dilemma of whether the treatment of choice should be conservative or surgical.

    Axon degeneration is an intrinsic self-destruction program that underlies axon loss during injury and disease. Sterile alpha and TIR motif containing 1 (SARM1) protein is an essential mediator of axon degeneration. We report that SARM1 initiates a local destruction program involving rapid breakdown of NAD+ after injury. We used an engineered protease-sensitized SARM1 to demonstrate that SARM1 activity is required after axon injury to induce axon degeneration. Dimerization of the Toll-Interleu...

Magnetic resonance imaging of the brain on admission revealed high-intensity signal areas in the bilateral putamina on diffusion-weighted and T2-weighted images as well as a high-intensity signal area in the left middle cerebellar peduncle that had been identified 3 years previously. We diagnosed bilateral optic neuropathy with bilateral putaminal lesions caused by preceding infection-triggered demyelination. We administered methylprednisolone, but his vision did not recover.

    The subscapular artery arises from the third part of the axillary artery and gives off the circumflex scapular and the thoracodorsal arteries. Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

    OBJECTIVE: The pathogenesis of diabetic papillopathy largely is unknown, but case reports suggest that it may follow rapidly improved metabolic control. The present study was designed to investigate this hypothesis. DESIGN: Retrospective case-control study. PARTICIPANTS: Two thousand sixty......-six patients with type 1 diabetes. METHODS: Review of clinical, photographic, and clinical chemistry records from a large diabetology and ophthalmology unit between 2001 and 2008. MAIN OUTCOME MEASURES: Simultaneous, bilateral diabetic papillopathy. RESULTS: The mean follow-up was 4.9 years. During 10 020...... patient-years of observation, bilateral diabetic papillopathy developed in 5 patients. During the year preceding this incident, all 5 patients had experienced a decrease in glycosylated hemoglobin A(1c) (HbA(1C)) at a maximum rate of -2.5 (mean) percentage points per quarter year, which was significantly...

    Summary Background To evaluate the safety, etiology and outcomes of patients undergoing bilateral thoracentesis. Methods This is a prospective cohort study of 100 consecutive patients who underwent bilateral thoracenteses in an academic medical center from July 2009 through November 2010. Pleural fluid characteristics and etiologies of the effusions were assessed. Mean differences in levels of fluid characteristics between right and left lungs were tested. Associations between fluid characteristics and occurrence of bilateral malignant effusions were evaluated. The rate of pneumothorax and other complications subsequent to bilateral thoracentesis was determined. Results Exudates were more common than transudates, and most effusions had multiple etiologies, with 83% having two or more etiologies. Bilateral malignant effusions occurred in 19 patients, were the most common single etiology of exudative effusions, and were associated with higher levels of protein and LDH in the pleural fluid. Among 200 thoracenteses performed with a bilateral procedure, seven resulted in pneumothoraces, three of which required chest tube drainage and four were ex vacuo. Conclusions More often than not, there are multiple etiologies that contribute to pleural fluid formation, and of the combinations of etiologies observed congestive heart failure was the most frequent contributor. Exudative effusions are more common than transudates when bilateral effusions are present. Malignancy is a common etiology of exudative effusions. This study suggests that the overall complication rate following bilateral thoracentesis is low and the rate of pneumothorax subsequent to bilateral thoracentesis is comparable to unilateral thoracentesis.

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    Cochlear implant surgery became the standard of care in hearing rehabilitation of patients with severe to profound sensorineural hearing loss. This procedure may alter the lives of children and adults enabling them to integrate with the hearing population. In the past, implantation was performed only in one ear, despite the fact that binaural hearing is superior to unilateral, especially in noisy conditions. Cochlear implantation may be performed sequentially or simultaneously. The "sensitive period" of time between hearing loss and implantation and between the two implantations, when performed sequentially, significantly influences the results. Shorter time spans between implantations improve the hearing results after implantation. Hearing success after implantation is highly dependent on the rehabilitation process which includes mapping, implant adjustments and hearing training. Bilateral cochlear implantation in children is recommended as the proposed procedure in spite of the additional financial burden.

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

    2015-01-01

    Bilateral Cochlear implants (CIs) improved speech intelligibility, speech perception in background noise, and sound localization in quiet and noisy situations. However, it is unclear whether these advantages essentially result in binaural integration of acoustic stimuli from each ear. In this study, we investigated the effectiveness of binaural integration by bilateral CIs placement using binaural hearing tests and subjective auditory perceptual assessment. A 61-year-old bilateral CIs subject underwent the following four tests:the Japanese Hearing in Noise Test (HINT-J), the dichotic listening test (DLT), the Rapidly Alternating Speech Perception (RASP) test, and subjective auditory perceptual assessment. The HINT-J score was significantly higher for bilateral CIs than for a unilateral CI. However, DLT and the RASP test revealed contradictory results. Subjective auditory perceptual assessment revealed active and bright impressions for bilateral hearing, which were also noisy and strong compared with those for unilateral hearing. The results of this study revealed that bilateral CIs improved speech perception in background noise and an improved auditory impression, although the bilateral integration abilities were not improved. This was probably because the patient was required to combine information from the two ears into a single perception in DLT and the RASP test. More longitudinal data should be collected and analyzed in future studies to evaluate the long-term effects of bilateral CIs.

    2011-01-01

    Destructive injury is defined as a very serious damage both to the bone and the soft tissues. But in clinical practice we found that in some fracture cases, the damage to soft tissues is not as severe as "destructive injury" indicates, whereas comminuted fractures still cannot show the severity of bone damage. Therefore we proposed a new term "destructive fractures" after combining the definition of destructive injury with typical clinic cases. Destructive fractures refer to the fractures whose osseous tissues are damaged too seriously to be repaired, but soft tissues, nerves and veins are less severely injured and can be repaired. From the year 2001 to 2010, 75 cases of destructive fractures were admitted in our department. According to whether the fractures interlinked with the external environment, together with the fracture sites, they were divided into 6 types: al type, closed diaphysis destructive fracture; a2 type, open diaphysis destructive fracture; b1 type, closed joint-involved destructive fracture; b2 type,open joint-involved destructive fracture; cl type, closed mixed destructive fracture; c2 type, open mixed destructive fracture. Corresponding clinical treatments were conducted for each type.The new classification criterion of destructivefracture is simple and practical and thus can be used as an important guide to make reasonable treatment plans for destructive fractures.

    Chondrules are millimeter-sized silicate spherules ubiquitous in primitive meteorites, but whose origin remains mysterious. One of the main proposed mechanisms for producing them is melting of solids in shock waves in the gaseous protoplanetary disk. However, evidence is mounting that chondrule-forming regions were enriched in solids well above solar abundances. Given the high velocities involved in shock models, destructive collisions would be expected between differently sized grains after passage of the shock front as a result of differential drag. We investigate the probability and outcome of collisions of particles behind a one-dimensional shock using analytic methods as well as a full integration of the coupled mass, momentum, energy, and radiation equations. Destruction of protochondrules seems unavoidable for solid/gas ratios ε ≳ 0.1, and possibly even for solar abundances because of 'sandblasting' by finer dust. A flow with ε ≳ 10 requires much smaller shock velocities (∼2 versus 8 km s{sup –1}) in order to achieve chondrule-melting temperatures, and radiation trapping allows slow cooling of the shocked fragments. Initial destruction would still be extensive; although re-assembly of millimeter-sized particles would naturally occur by grain sticking afterward, the compositional heterogeneity of chondrules may be difficult to reproduce. We finally note that solids passing through small-scale bow shocks around few kilometer-sized planetesimals might experience partial melting and yet escape fragmentation.

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

    Full Text Available Simultaneous bilateral primary pneumothorax is a very rare (1.6 / 100,000 and life-threatening condition. Clinical presentation may vary from mild dyspnea to tension pneumothorax. It may be milder particularly in younger patients, but more severe in patients with advanced age, and tube thoracostomy is a life preserver in the latter group. Since mortality and recurrence rates following tube thoracostomy are high, endoscopic approaches to bilateral hemithorax have been reported in literature. Apical wedge resection and pleural procedures are recommended in video thoracoscopy or mini thoracotomy even if no bulla and/or bleb are detected. Bilateral surgical interventions and additional pleural procedures are associated with increased rate of post-operative complications and longer postoperative hospital-stays. As a first-line approach, the surgical method toward any side of lung with air leakage following a previous tube thoracostomy is considered less invasive, especially in younger patients. Here, we present a case of simultaneous bilateral primary spontaneous pneumothorax (SBPSP in a 21-year old male with no history of smoking and chronic pulmonary disease. A unilateral surgical intervention was performed, and no recurrence was observed during 5-year follow up.

    A multitude of different diseases can result in bilateral thalamic lesions. These include vascular pathologies requiring prompt therapeutic intervention, such as basilar thrombosis or thrombosis of the internal cerebral veins, as well as tumors, infectious or demyelinating diseases, and toxic-metabolic lesions. Therefore, detailed knowledge of the typical radiological findings for the various diseases is essential for determining the correct diagnosis. This review provides a synopsis of the radiological findings for the most important bithalamic lesions and an overview of the literature.

    While emotional intelligence may have a favourable influence on the life and psychological and social functioning of the individual, indirect self-destructiveness exerts a rather negative influence. The aim of this study has been to explore possible relations between indirect self-destructiveness and emotional intelligence. A population of 260 individuals (130 females and 130 males) aged 20-30 (mean age of 24.5) was studied by using the Polish version of the chronic self-destructiveness scale and INTE, i.e., the Polish version of the assessing emotions scale. Indirect self-destructiveness has significant correlations with all variables of INTE (overall score, factor I, factor II), and these correlations are negative. The intensity of indirect self-destructiveness differentiates significantly the height of the emotional intelligence and vice versa: the height of the emotional intelligence differentiates significantly the intensity of indirect self-destructiveness. Indirect self-destructiveness has negative correlations with emotional intelligence as well as its components: the ability to recognize emotions and the ability to utilize emotions. The height of emotional intelligence differentiates the intensity of indirect self-destructiveness, and vice versa: the intensity of indirect self-destructiveness differentiates the height of emotional intelligence. It seems advisable to use emotional intelligence in the prophylactic and therapeutic work with persons with various types of disorders, especially with the syndrome of indirect self-destructiveness.

    1990-01-01

    Bio-Imaging Research's technology that originated in an aerospace program has come full circle with a new aerospace adaptation called the Advanced Computed Tomography Inspection System, or ACTIS. The medical version of CT scans the human body for tumors or other abnormalities, the ACTIS system finds imperfections in aerospace structures and components, such as castings, assemblies, rocket motors and nozzles. ACTIS is described by its developer as the most versatile CT scanner available for non-destructive testing applications. ACTIS is a variable geometry system. ACTIS source and detectors can be moved closer together or farther apart to optimize the geometry for different sizes of test objects. The combination of variable geometry, three sources, and focusing detectors makes ACTIS cost effective for a broad range of applications. System can scan anything from very small turbine blades to large rocket assemblies.

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

    Full Text Available Lhermitte-Duclos disease (LDD is a pathologic entity with progrediating, diffuse hypertrophy chiefly of the stratum granulosum of the cerebellum. Typically LDD is a unilateral lesion of the cerebellum or in vermis. Here we report a case of LDD with bilateral lesions of cerebellar hemispheres managed surgically. A 28-year-old woman presented with one-year history of progressive headache, nausea, vomiting, and blurred vision. Neurologic examination revealed a bilateral mild papilledema, mild dysmetria, and dysdiadochokinesia. The cerebellar lesions caused moderate mass effect in posterior fossa with hydrocephalus, and Chiari type I malformation. We performed the suboccipital-retrosigmoid approach, and removed completely the left intracerebellar mass. Symptoms related to elevated intracranial pressure disappeared in a short period postoperatively.

    Bilateral patellae fractures represent a rare entity, accounting for approximately 2.9% of all lesions interesting in this anatomical district. In most cases found in the published work, they are described as stress fractures or as complications of chronic diseases such as osteoporosis, renal failure and secondary hyperparathyroidism. Although many pathogenetic mechanisms have been supposed, none have been proved for certain. Insufficiency fractures of the patellae are rare events and no data has been published on their incidence. We present a case of bilateral fracture of the patellae due to an indirect trauma occurring in an 85-year-old patient affected by Parkinson's disease, osteoporosis and diffuse degenerative osteoarthritis. X-ray of the knees (anteroposterior and lateral) and magnetic resonance imaging evaluation confirmed the fractures. The patient was treated conservatively. She had a good result, returning to her previous autonomous ambulation. This case is unusual because there was no direct trauma to the knees because of bilaterality, but confirmed previous observations about insufficiency fractures of patellae in the presence of comorbidity. Insufficiency fractures of patellae can be an insidious condition in elderly people. Prepatellar pain, a common symptom in the relapse phase of degenerative arthritis of the knee, should not be underestimated, particularly in patients with diseases influencing metabolism of bone and with an elevated risk of fall. A periodical clinical and instrumental follow up should be done in these patient. Moreover, we underline the necessity of a multidisciplinary approach.

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

    The γ -ray emission associated with the radioactive decay of 26Al is one of the key pieces of observational evidence indicating stellar nucleosynthesis is an ongoing process in our Galaxy, and it was the first such radioactivity to be detected. Despite numerous efforts in stellar modeling, observation, nuclear theory, and nuclear experiment over the past four decades, the precise sites and origin of Galactic ^{26} Al remain elusive. We explore the present experimental knowledge concerning the destruction of ^{26} Al in massive stars. The precise stellar rates of neutron-induced reactions on ^{26} Al, such as (n,p) and (n, α , have among the largest impacts on the total ^{26} Al yield. Meanwhile, reactions involving the short-lived isomeric state of ^{26} Al such as radiative proton capture are highly-uncertain at present. Although we presented on-going experimental work from n_TOF at CERN with an ^{26} Al target, the present proceeding focuses only on the ^{26} Al isomeric radioactive beam production aspect and the first experimental results at CRIB.

    We report a rare case of bilateral primary adrenal non-Hodgkin's lymphoma with adrenal failure. A 66-year-old woman developed symptoms of adrenal failure. The cause of adrenal failure was suspected to be malignant lymphoma based on the high levels of serum soluble interleukin-2 receptor and LDH. Bilateral adrenalectomy was performed and pathological examination showed intravascular large B-cell lymphoma (IVL). Although complete remission was achieved, recurrence occurred three months later with brain metastases. IVL should be suspected in patients with bilateral adrenal tumors who present with rapidly progressive adrenal failure.

    Postoperative maxillary cysts are locally aggressive lesions, usually developing as delayed complications many years after radical antral surgery. This report describes a case of bilateral postoperative maxillary cysts following orthognathic surgery performed approximately 21 years previously. The patient complained of stinging pain on her right cheek. Radiographic examination revealed low-attenuation lesions on both maxillary sinuses with discontinuously corticated margins without distinct expansion or bone destruction. The cysts were enucleated with the removal of metal plates and screws for pain relief. Histopathological examination confirmed the diagnosis of postoperative maxillary cysts lined by ciliated, pseudostratified columnar cells. The patient has remained asymptomatic thus far, and there was no evidence of local recurrence at 21 months of postoperative follow-up.

    2009-01-01

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

    The Lawrence Livermore National Laboratory in conjunction with the Energetic Materials Center is developing methods for the safe and environmentally sound destruction of explosives and propellants as a part of the Laboratory`s ancillary demilitarization mission. LLNL has built a small-scale unit to test the destruction of HE using the Molten Salt Destruction (MSD) Process. In addition to the high explosive HMX, destruction has been carried out on RDX, PETN, ammonium picrate, TNT, nitroguanadine, and TATB. Also destroyed was a liquid gun propellant comprising hydroxyammonium nitrate, triethanolammonium nitrate and water. In addition to these pure components, destruction has been carried out on a number of commonly used formulations, such as LX-10, LX-16, LX-17, and PBX-9404.

    Full Text Available Introduction. In 1814 Giovanni Monteggia first described two cases of fractures of the proximal third of ulna with dislocation of the radial head. These fractures are more common in children than in adults, and mutual Monteggia fracture is a rare complication. This study presents a treatment course of a patient with bilateral Monteggia fracture. Case report. A 55- year-old patient was injured by falling in the yard. Radiography showed bilateral Monteggia fracture type II (by the Badon classification. Operative treatment of fracture was done by a compression plate on the right side and by the zuggurtung technique on the left one. Closed repositioning of the radial head was done on both sides. The patient was wearing a plaster splint for the upper arm for 21 days. After removing the fixation, the function of the elbow was determined by the Broberg Morrey score (BM which was on the right side 45.5 and on the left side 47.5. After the proper physical therapy, four months after the surgery, BM score was 100 on the right side, and 93 on the left one. Conclusion. Surgical treatment and early rehabilitation is the key for the return of good function of both elbows.

    A 35-year-old man presented with asymptomatic eruption on both forearms and lower aspects of the legs for 6 months. The lesions first appeared on his inner aspects of the wrist, the dorsal surface of the hands, and legs and progressed to involve proximal aspects of the extremities. There was no significant past history. On examination, multiple pearly white papules and depigmented atrophic plaques were found bilaterally on the flexors of the arms and the extensors of the legs. The lesions were arranged in a linear manner, following the lines of Blaschko (Figures 1 and 2). The surface of the atrophic plaques was notable for prominent telangiectasia, giving an erythematous appearance. The genitalia, oral cavity, palms, and soles were spared. Systemic examination was noncontributory. Lichen striatus and extragenital lichen sclerosus (ELS) were considered the differential diagnosis. Clinically, the age of the patient, the absence of scaling, and the presence of atrophic plaques and telangiectasia were in favor of ELS. A punch biopsy from an atrophic plaque was performed, and it revealed hyperkeratosis, atrophic epidermis, basal layer vacuolar degeneration, mild lymphocytic infiltration in the dermis, edema, and homogenization of collagen of the upper portion of the dermis (Figures 3 and Figure 4). Histopathologic findings were consistent with lichen sclerosus. A diagnosis of bilateral zosteriform ELS was made.

    Full Text Available Abstract How to Cite This Article: Inaloo S, Katibeh P. Guillain-Barre Syndrome Presenting With Bilateral Facial Nerve Palsy. Iran J Child Neurol. 2014 Winter;8(1:69-71. Objective This case study is about an 11-year-old girl with bilateral facial weakness, abnormal taste sensation, and deep tendon reflexes of both knees and ankles were absent. However, the muscle power of the lower and upper extremities across all muscle groups was normal. After 2 days, she developed paresthesia and numbness in the lower extremities. Other neurologic examinations, such as fundoscopic evaluation of the retina were normal with the muscle power of both upper- and lower-extremities intact. A lumbar puncture revealed albumincytological dissociation. EMG and NCV were in favor of Guillain-Barre syndrome, for which IVIG was prescribed and the abnormal sensations in the lower limbs rapidly improved. Bilateral facial diplegia without weakness and paresthesia is a variant of Guillain-Barre syndrome that mostly presents with acute onset, rapid progression with or without limb weakness, paresthesia, and decreased or absent DTR and albumin-cytological dissociation.

    To discuss the role of bilateral adrenalectomy in Cushing syndrome, as illustrated in a case of severe hypercortisolism that was unresponsive to combination agent medical therapy. We report the clinical, laboratory, imaging, and pathologic findings in a patient with ectopic Cushing syndrome attributable to an adrenocorticotropic hormone (ACTH)-secreting neuroblastoma. In addition, we provide a literature review regarding olfactory neuroblastoma and discuss current and emerging therapeutic options for Cushing syndrome. A 59-year-old man presented with nasal congestion and neck swelling and was noted to have hypokalemia, hypertension, and hyperglycemia. A nasal biopsy demonstrated a poorly differentiated carcinoma with neuroendocrine features. He was subsequently diagnosed as having ACTH-dependent Cushing syndrome, but despite high-dose combination medical therapy, his condition rapidly deteriorated. Urgent bilateral adrenalectomy provided rapid control of the hypercortisolism, and the patient was later able to undergo an uncomplicated total macroscopic resection of his locally metastatic primary tumor. This report describes the challenges in the diagnosis and management of ACTH-dependent Cushing syndrome and highlights the important role that bilateral adrenalectomy can still have in patients with severe hypercortisolism causing life-threatening complications.

    The uncommon variant of degenerative hip joint disease, termed rapidly progressive osteoarthritis, and highlighted by severe joint space loss and osteochondral disintegration, is well established. We present a similar unusual subset in the lumbar spine termed destructive discovertebral degenerative disease (DDDD) with radiological features of vertebral malalignment, severe disc resorption, and "bone sand" formation secondary to vertebral fragmentation. Co-existing metabolic bone disease is likely to promote the development of DDDD of the lumbar spine, which presents with back pain and sciatica due to nerve root compression by the "bone sand" in the epidural space. MRI and CT play a complimentary role in making the diagnosis.

    2011-10-01

    Full Text Available Mucoceles of the paranasal sinuses are slowly growing, epithelium-lined cystic lesions with sterile content. When the mucocele content becomes infected with a bacterial super-infection, the lesion is defined as mucopyocele. Mucoceles or mucopyoceles are commonly located in the frontal and anterior ethmoidal sinuses and can manifest with ocular signs and symptoms, mostly proptosis. In this report, we demonstrate a case of bilateral ethmoidal mucopyocele in a 53-year-old female who presented with reduced vision, diplopia, and proptosis. Computed tomography (CT scanning of the paranasal sinuses revealed cystic lesions filling the maxillary sinuses and anterior ethmoidal cells bilaterally and causing erosion in the walls of the sinuses. After marsupialization of the mucopyoceles was performed by endoscopic sinus surgery, the symptoms of the patient recovered rapidly. (Turk J Ophthalmol 2011; 41: 354-6

    Cochlear implantation is a standard method of hearing rehabilitation among patients with severe to profound bilateral sensorineural hearing loss. In recent years there have been an increasing number of studies showing superior hearing with bilateral cochlear implantation in comparison with a unilateral procedure. In this study we present our experience with 15 patients, children and adults, who had bilateral cochlear implant surgery. Speech perception test results demonstrated a hearing benefit in bilateral cochlear implantation in comparison with a unilateral device, mainly by improvement in the identification of speech in noise tests.

  2. Entropic destruction of a moving heavy quarkonium

    2015-01-01

    Recently it has been shown that the peak of the quarkonium entropy at the deconfinement transition is related to the emergent entropic force which destructs the quarkonium. Using the AdS/CFT correspondence, we consider dissociation of a moving heavy quarkonium by entropic force. We find that the entropic force destructs the moving quarkonium easier than the static case which is expected from perturbative weakly coupled plasma. By considering the Maxwell charge, we study the effect of medium on the destruction of heavy quarkonium. It is shown that the quarkonium dissociates easier in the medium.

    The non-destructive identification of the orbital angular momentum (OAM) is essential to various applications in the optical information processing. Here, we propose and demonstrate experimentally an efficient method to identify non-destructively the OAM by using a modified Mach-Zehnder interferometer. Our schemes are applicable not only to the case with integer charges, but also to optical vortices with noninteger charges. Our Letter presents the first experimental demonstration of the non-destructive identification of twisted light with integer or noninteger topological charges, which has potential applications in the OAM-based data transmission for optical communications.

    Iatrogenic Cushing syndrome induced by oral and parenteral corticosteroid administration is a well-known complication, and necessary precautions have to be taken. Cushing syndrome, however, following treatment with glucocorticoid-containing eye drops is a very rare complication. To the best of our knowledge, there have been only four reported cases in the literature. Herein, we present an infant boy who developed Cushing syndrome after receiving dexamethasone-containing eye drops after bilateral cataract extraction to prevent postoperative inflammatory complications. At the age of 5 months, after approx. 3 months of dexamethasone therapy, the patient presented with cushingoid facies, nephrocalcinosis and failure to grow. Iatrogenic Cushing syndrome was diagnosed and dexamethasone-containing eye drops were reduced and eventually stopped. Follow-up examinations revealed catch-up growth. Ocularly administered corticosteroids may have substantial systemic side effects in infants.

    Full Text Available Introduction: HIV/AIDS is now a global epidemic that has become the leading infectious killer of adults worldwide. Although antiretroviral (ARV therapy has dramatically improved the quality of life and increased the life expectancy of those infected with HIV but frequency of dosing and drug toxicity as well as the development of viral resistance pose additional limitations. The rapidly expanding field of nanotechnology has vast potential to radically advance the treatment and prevention of HIV/AIDS. Nanoparticles can provide improved drug delivery, by virtue of their small size, robustness, safety, multimodality or multifunctionality. Aims and objectives: Since HIV primarily infects CD4+ cells; we aim to use CD4 as a selectable target to deliver a pro-apoptotic protein to HIV-infected cells using nanoparticles as carriers. The aim of study was to develop a nanotechnology-based death inducing delivery system for the destruction of CD4+HIV infected cells through the activation of caspase-3. Methodology: A modified caspase-3 protein (Mut-3 was engineered, which is cleavable only by HIV-1 protease. Mut-3 can activate apoptosis in the presence of HIV-1 protease, consequently killing HIV-positive cells. Mut-3 protein was conjugated to gold nanoparticles together with a CD4-targeting peptide. The efficacy of the gold nanoparticles was tested on CHO cells that were genetically engineered to express GFP labelled CD4 and HIV-1 protease. Results: Mut-3 was expressed in bacterial cells and purified. CHO cells that stably over express CD4-GFP and HIV-1 protease were selected using Fluorescence Activated Cell Sorting. Dose response cell culture experiments showed that gold nanoparticles without Mut-3 and CD4-targeting peptide did not induce cell death in CHO cells, while gold nanoparticles that was conjugated with Mut-3 and the CD4-targeting peptide rapidly induced cell death in CHO cells. Conclusions: Our results suggest that gold nanoparticles conjugated

    In bilateral thumb amputations, the functional impairment is serious and every attempt should be made to reconstruct the thumb. We report a case of bilateral post traumatic thumb amputation, reconstructed with bilateral second toe transfer. Only two such cases have been reported in literature so far. Though there are various modalities for the reconstruction of thumb, microvascular toe transfer has its own merits. The convalescent period is minimal with excellent function. It is bilaterally s...

    Full Text Available First rib fractures are scarce due to their well-protected anatomic locations. Bilateral first rib fractures accompanying bilateral scapular fractures are very rare, although they may be together with scapular and clavicular fractures. According to our knowledge, no case of bilateral first rib fractures accompanying bilateral scapular fractures has been reported, so we herein discussed the diagnosis, treatment, and complications of bone fractures due to thoracic trauma in bias of this rare entity.

    To simulate numerically a non-destructive by eddy current testing (NDT-CF), the sensor response can be modeled through a semi-analytical approach by volume integral equations. Faster than the finite element method, this approach is however restricted to the study of plane or cylindrical parts (without taking into account the edge effects) because of the complexity of the expression of the dyadic Green function for more general configurations. However, there is an industrial demand to extend the capabilities of the CF model in complex configurations (deformed plates, edges effects...). We were thus brought to formulate the electromagnetic problem differently, by setting ourselves the goal of maintaining a semi-analytical approach. The surface integral equation (SIE) expresses the volume problem by an equivalent transmission one at the interfaces (2D) between homogeneous sub-domains. This problem is approached by a linear system (by the method of moments), whose number of unknowns is reduced due to the nature of the surfacic mesh. Therefore, this system can be solved by a direct solver for small configurations. That enabled us to treat several various positions of the sensor for only one inversion of the impedance matrix. The numerical results obtained using this formulation involve plates with consideration of edge effects such as edge and corner. They are consistent with results obtained by the finite element method. For larger configurations, we conducted a preliminary study for the adaptation of an acceleration method of the matrix vector product involved in an iterative solver (fast multipole method or FMM) to define the conditions under which the FMM calculation works correctly (accuracy, convergence...) in the NDT's domain. A special attention has been given to the choice of basis functions (which have to satisfy an Hdiv conforming property) and on the evaluation of near interactions (which are weakly singular).

    The research results indicate that, as compared with the group of heterosexual individuals, in the group of homosexuals there occurs a worsening in psychological functioning, which may be also manifested by an increased indirect self-destructiveness index. The increased intensity of indirect self-destructiveness in homosexual individuals may be considered a manifestation of worsened psychological functioning. The homosexual individuals look after their health similarly to heterosexuals.

    Full Text Available Bilateral ectopic pregnancy is a rare twin gestation with only a few cases reported in the literature. We report a 30 year old woman without any high risk factor for ectopic pregnancy, who had concurrent bilateral ectopic pregnancy. A 30 year old female presented to the Gynecology emergency department complaining of vaginal bleeding and abdominal pain. The presumptive diagnosis of ruptured left sided ectopic pregnancy was made on basis of clinical findings and ultrasound finings. An emergency laparotomy was done revealed a hemoperitoneum of 1.5 liters, a ruptured left tubal pregnancy with active bleeding and right tubal un-ruptured ectopic was found. A bilateral salpingectomy was performed. Histopathology confirmed presence of chorionic villi in both tubes. In theory, laparoscopic salpingostomy is the best surgical approach in bilateral tubal pregnancy. However, bilateral salpingectomy may be necessary when both tubes are extensively damaged or are actively bleeding. Successful pregnancies have been reported after conservative surgical treatment of bilateral ectopic, but the risk of recurrence is high. Our decision for an emergency laparotomy followed by bilateral salpingectomy was based on the fact that the patient presented with acute abdomen and was haemodynamically unstable and there was extensive bilateral tubal damage. As the incidence of ectopic pregnancies is increasing concurrently with the incidences of pelvic inflammatory disease and use of assisted fertility techniques; it may be that these and ldquo;rare ectopics and rdquo; will become less uncommon.

    Epithelial-myoepithelial carcinoma (EMC) is a rare tumor that commonly involves the salivary glands. EMC arising from the nasal cavity is one of the most unusual cases. We describe a case of a 48-year-old patient who is presented with bilateral nasal obstruction for several months. Multidetector computed tomography reveals expansile, well-defined, heterogeneous enhancing soft tissue masses filling the nasal cavity with bony destruction of hard palate and maxillary alveolar ridge. The carcinoma was histologically characterized by a mixture of trabecular structure with myoepithelial cells and ductal cells, which are confirmed by electron microscopy and immunohistochemistry.

The analysis is based on the gravity model of bilateral trade; a structural model developed over decades and now the central model in analyses of bilateral trade flows...... and trade policies. The main result of the study is that Danish bilateral aid has a positive and statistically significant impact on Danish exports to the recipient countries. Bilateral development assistance may affect exports through several channels. Three of the main channels are direct aid tying......; increasing recipient income where higher income leads to higher imports, and decreased trade costs, say due to improved information about cultural and administrative customs and practices. Thus, as for preferential trade arrangements, bilateral aid has two potential economic effects; trade creation working...

    We introduce a new type of multiple zeta functions, which we call bilateral zeta functions, analogous to the Barnes zeta functions. The bilateral zeta function is a periodic function and shares certain basic properties of Barnes zeta function. Especially, we prove that the bilateral zeta function has a nice Fourier series expansion and the Barnes zeta function can be expressed as a finite sum of bilateral zeta functions. By these properties of the bilateral zeta functions, We obtain simple proofs of some formulas, for example the reflection formula for the multiple gamma function, the inversion formula of the Dedekind eta function, Ramanujan's formula, Fourier expansion of the Barnes zeta function and multiple Iseki's formula.

    completely.Amplifying EncountersFor stars that survive their encounter with the black hole, Guillochon and McCourt find that the process of partial disruption and re-accretion can amplify the magnetic field of the star by up to a factor of 20. Repeated encounters of the star with the black hole could amplify the field even more.The authors suggest an interesting implication of this idea: a population of highly magnetized stars may have formed in our own galactic center, resulting from their encounters with the supermassive black hole Sgr A*.A turbulent magnetic field forms after a partial stellar disruption and re-accretion of the tidal tails. [Adapted from Guillochon McCourt 2017]Effects in DestructionFor stars that are completely shredded and form a tidal stream after their encounter with the black hole, the authors find that the magnetic field geometry straightens within the stream of debris. There, the pressure of the magnetic field eventually dominates over the gas pressure and self-gravity.Guillochon and McCourt find that the fields new configuration isnt ideal for powering jets from the black hole but it is strong enough to influence how the stream interacts with itself and its surrounding environment, likely affecting what we can expect to see from these short-lived events.These simulations have clearly demonstrated the need to further explore the role of magnetic fields in the disruptions of stars by black holes.BonusCheck out the full (brief) video from one of the simulations by Guillochon and McCourt (be sure to watch it in high-res!). It reveals the evolution of a stars magnetic field configuration as the star is partially disrupted by the forces of a supermassive black hole and then re-accretes.CitationJames Guillochon and Michael McCourt 2017 ApJL 834 L19. doi:10.3847/2041-8213/834/2/L19

    Hashimoto's encephalopathy often presents with neuropsychiatric manifestations including seizures and movement disorders. We describe a patient who presented with bilateral hand tremor and mild cognitive defects that fulfilled the criteria for a diagnosis of Hashimoto's encephalopathy. There was a rapid response to glucocorticoid therapy with relapse following treatment withdrawal. Recently published clinical criteria for the diagnosis of Hashimoto's encephalopathy include seizures, myoclonus, hallucinations, or stroke-like episodes but do not include tremor. Our case had mild cognitive dysfunction and a coarse tremor as the predominant clinical features, which probably represent mild disease.

    Full Text Available Objectives: The objective of this study was to examine the sex (gender differentiation of indirect self-destructiveness intensity and its manifestations, as well as relationships between indirect self-destructiveness and its manifestations (categories and the psychological dimensions of masculinity and femininity, also from the point of view of assessing occupational health and safety. Materials and Methods: A population of 558 individuals (399 females and 159 males aged 19–25 (mean age: 22.6 was studied. The Polish version of the “Chronic Self-Destructiveness Scale” (CS-DS by Kelley adapted by Suchańska was used in order to examine indirect self-destructiveness and its manifestations. Gender testing applied the Polish version of the Bem Sex Role Inventory (BSRI by Bem in its adaptation by Kuczyńska. Results: Males’ scores are signifi cantly higher than those of females for the majority of CS-DS scales/indices: Indirect Self-Destructiveness (general index, Poor Health Maintenance (A2, Lack of Planfulness (A4, and Helplessness, Passiveness (A5. Moreover, there are statistically signifi cant correlations between CS-DS scales and the masculinity dimension (positive as well as the femininity dimension (negative. Conclusions: Masculinity is a factor that may predispose towards indirectly self-destructive behaviors, while femininity is a factor protecting against those. The study results may prove useful in preventing indirectly and directly self-destructive behaviors as well as in therapy work with the individuals who display such tendencies or have made attempts on their own lives, in particular taking into account their being of a specifi c sex/gender and in the context of work (especially in diffi cult or dangerous conditions or both.

    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.

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

    Full Text Available Total hip replacement in children is performed according to very limited and compelling indications. The principal of such a treatment is the complete and irreversible destruction of the hip joint accompanied by a permanent loss of function of the lower limb. Hip replacement in children with cerebral palsy is a very rare method of treatment. According to observations from the Turner Institute, it was performed in only 2% of all replacement cases. After the placement of an artificial joint, the atherogenic component of the contractures disappears and improves the motor activity of patients. In this paper, a 3-year follow-up of the bilateral total hip replacement in a child with cerebral palsy and bilateral secondary stage III coxarthrosis is presented.

    Bilateral amputations of upper limbs are excessively rare clinical situations. We report an exceptional clinical case of bilateral amputation of upper limbs at different levels: destruction of the right hand and left transhumeral amputation in a patient after an attempted suicide on train lines. This special situation led us to perform a cross-hand replantation of the left hand to the right forearm. Only 4 other similar cases have been published in the literature. Once the surgical indication had been formulated collectively, and taking into account all the ethical issues surrounding such a decision, we had to solve the issue of inverting anatomical structures in emergency. We have provided a detailed description of our surgical technique. The aim was to save at least one organ used for grasping. The result obtained is presented and reviewed.

    Multiple myeloma is a hematologic malignancy associated with destructive bone loss. Lytic lesions, a hallmark of this cancer, can result in significant morbidity because of associated pain and structural osseous compromise. Osteoplasty has demonstrated efficacy in the treatment of myelomatous pain within the axial skeleton; however, there is limited evidence supporting the utility of osteoplasty to treat extra-spinal lesions. We describe a 67 year-old woman with stable IgA lambda multiple myeloma with sentinel bilateral greater trochanteric lytic lesions that was referred to our interventional pain management clinic for evaluation of bilateral lateral hip pain. Conservative treatment options including physical therapy, non-steroidal anti-inflammatory drugs (NSAIDs), oral opiates, and local corticosteroid injections to bilateral trochanteric bursae failed to offer pain relief. The patient underwent minimally invasive percutaneous trochanteroplasty with concomitant core biopsy of her bilateral trochanteric lytic lesions. The intended goals of this novel procedure were to determine the cause of the suspected lytic lesions, provide pain relief, and offer structural stability by safely implanting bone cement as part of a fracture prevention strategy. At 12 month follow-up, the patient's pain improved by 70% and she no longer required the use of pain medication. The patient also displayed a significant improvement in her day-to-day functioning and quality of life.

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

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

    Full Text Available Tessier cleft 3 is a very rare congenital anomaly, (2 especially the bilateral form. Very few cases have been reported worldwide. (1,2 I report a case of bilateral Tessier cleft 3 presenting at the age of three months with clefts extending from philtral regions, undermining the nasal alar bases to the medial canthal areas bilaterally. There were bilateral complete alveolar clefts with mild protrusion of the pre-maxilla, but the rest of the maxilla including the palate was not involved. Surgical correction was started at the age of three months and completed at the age of one and half years in three stages. There was no intra-operative or postoperative complications and the final result was satisfactory.

    We report a case of bilateral pneumolabyrinth presenting as sudden, bilateral deafness, without temporal bone fracture, after a fall. A 49-year-old man presented with sudden, bilateral deafness and whirling vertigo, without any other neurological manifestations. Temporal bone computed tomography clearly demonstrated the presence of air in the vestibule and cochlea on both sides. However, there was no definite fracture line, ossicular chain anomaly or soft tissue density in the temporal bone or middle-ear cavity. The patient was treated conservatively. Unfortunately, there was no improvement in his hearing. Pneumolabyrinth is an uncommon condition in which air is present in the vestibule or cochlea. It is rarely found, even with fractures violating the otic capsule or with transverse fractures of the temporal bone. In addition, its bilateral occurrence is extremely rare. In this article, we describe a case of bilateral pneumolabyrinth presenting as sudden, bilateral deafness, without temporal bone fracture, an occurrence which has not previously been reported.

    Full Text Available Adrenal haemorrhage is a rare cause of adrenal crisis, which requires rapid diagnosis, prompt initiation of parenteral hydrocortisone and haemodynamic monitoring to avoid hypotensive crises. We herein describe a case of bilateral adrenal haemorrhage after hemicolectomy in a 93-year-old female with high-grade colonic adenocarcinoma. This patient’s post-operative recovery was complicated by an acute hypotensive episode, hypoglycaemia and syncope, and subsequent computed tomography (CT scan of the abdomen revealed bilateral adrenal haemorrhage. Given her labile blood pressure, intravenous hydrocortisone was commenced with rapid improvement of blood pressure, which had incompletely responded with fluids. A provisional diagnosis of hypocortisolism was made. Initial heparin-induced thrombocytopenic screen (HITTS was positive, but platelet count and coagulation profile were both normal. The patient suffered a concurrent transient ischaemic attack with no neurological deficits. She was discharged on a reducing dose of oral steroids with normal serum cortisol levels at the time of discharge. She and her family were educated about lifelong steroids and the use of parenteral steroids should a hypoadrenal crisis eventuate.

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

    Full Text Available Objective. Improve the effectiveness of surgical treatment in patients with bilateral destructive pulmonary tuberculosis by mini-invasive resection and collapse therapy. Materials and Methods: Retrospective analysis of 222 patients’ cards with bilateral destructive pulmonary tuberculosis who were treated in the period from 1995 to 2014 in the thoracic department of Dnepropetrovsk regional clinical therapeutic and prophylactic association "Phthisiology". Patients were divided into 2 groups: basic (111 patients who underwent mini-invasive surgery and control (111 patients, who underwent standard surgical approach. The distribution of patients in investigated groups was representative by the majority of parameters. Results and discussion. The average duration of simultaneous bilateral VATS lung resections was 1,90 ± 0,12 hour, standard thoracotomies - 2,13 ± 0,19 per hour, estimated blood loss was 234±5,20ml and 433±3,70ml respectively. The average postoperative time in-patient was 52,40±2,63 days in basic and 80,10±3,58 days in the control group. Number of postoperative complications after lung resection with VATS was significantly lower (1.6 times, as compared with standard surgical approach. Volume of blood loss less than 400 ml was 93,40±3,20% in basic and 72,60±4,80% in the control group, the amount of intraoperative complications reduced by 2.2 times. Complete clinical response (decontamination and closing of cavities have been achieved in patients of the basic group by 1.6 times more often. Conclusions: For patients with bilateral pulmonary tuberculosis to perform mini-invasive surgical approach is the best option. Mini-invasive interventions with VATS due to its good abilities to visualize tissues and anatomical structures may significantly decrease the amount of intraoperative blood and plasma loss in the first postoperative day. It leads to the stabilization of tuberculosis process in the contralateral lung, responsible for

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

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

    Hail is considered to be among the most complex extreme weather phenomena of the atmosphere. Every year, notably in the southern Brazilian States, destructive hailstorms result in serious economic losses and cause a great social impact destroying crops, homes, medical facilities and schools. The aim of this study is to document the spatial, annual, and diurnal variation in destructive hailstorm frequency during a 22 year period from 1991 to 2012 in Brazil. The analysis is based on a collection of reports released by the Brazilian National Civil Protection Secretariat - SEDEC. Based on reports of emergency assistance given to the population affected by a disaster, the information discussed in this work is assumed as representative only of destructive hailstorms. The analysis reveals a large spatial variability, with the majority of hailstorm occurrences distributed in the three southernmost Brazilian States. Within those states, the number of hail reports was observed to increase with increasing population density in rural areas. Hailstorms were reported most often in the late afternoon and evening of the winter/spring transition, in agreement with a few other areas in the subtropics with available studies, but different from the majority of studies for temperate zones, which suggest spring/summer as the hail season. Although the results show some discrepancies compared to satellite hail signatures, the findings of this work confirm that southern Brazil is a region prone to the development of strong convective storms, with high annual numbers of destructive hail events.

    Using the AdS/CFT duality, we study the destruction of a rotating heavy quarkonium due to the entropice force in $\\mathcal{N}=4$ SYM theory and a confining YM theory. It is shown that in both theories increasing the angular velocity leads to decreasing the entropic force. This result implies that the rotating quarkonium dissociates harder than the static case.

    In bilateral thumb amputations, the functional impairment is serious and every attempt should be made to reconstruct the thumb. We report a case of bilateral post traumatic thumb amputation, reconstructed with bilateral second toe transfer. Only two such cases have been reported in literature so far. Though there are various modalities for the reconstruction of thumb, microvascular toe transfer has its own merits. The convalescent period is minimal with excellent function. It is bilaterally symmetric and aesthetically superior to the osteoplastic reconstruction. The technical details are discussed, and the long term functional and aesthetic results are presented.

    1997-02-01

    Full Text Available Massive destruction of parasitized splenic macrophages was histologically observed at the height of a virulent infection caused by Trypanosoma cruzi (Y strain in the mouse. This was coincident with a sudden drop in parasitemic curve. Most of the animals died at this point, probably due to the liberation of toxic products, such as TNF, following the massive destruction of parasitized cells. However, parasitized-cell destruction indicated the transition from susceptibility to resistance. Although it has been extensively studied in vitro, this study contributes with the morphological counterpart observed in vivo by optical and electron microscopy. When infected animals were specifically treated during early infection transition to chronic phase was immediately observed without splenic parasitism. Animals that apparently recovered from massive cell-destruction in the spleen showed evidences of a rapid restoration of splenic architecture.Um estudo histologico sequenciado mostrou que o parasitismo dos macrófagos esplênicos por uma cepa virulenta (cepa Y do Trypanosoma cruzi tem um curso progressivo, mas chega até um ponto em que todos as células parasitadas são subitamente destruídas. Tal achado coincidiu com uma quéda brusca da curva parasitêmica e com a morte da maioria dos animais, provavelmente devido à liberação de produtos tóxicos (como o TNF pelas células desintegradas. O achado foi interpretado como o auge da transição entre uma fase de susceptibilidade e outra de resistência. Embora esta transição tenha sido bem estudada in vitro, este estudo contribui com os dados do substrato morfológico observados in vivo, através da microscopia ótica e eletrônica. O tratamento específico e supressivo feito na fase inicial da infecção acarreta uma transição imediata para a fase crônica e aí o parasitismo esplênico desaparece completamente.

    2016-01-01

    Recent published data have suggested successful union of subtalar and tibiotalar joints without formal debridement during tibiotalocalcaneal (TTC) fusion procedures. Although previous studies have reported on the importance of the proper guidewire starting point and trajectory to obtain appropriate hindfoot alignment for successful fusion, to our knowledge, no studies have quantified the amount of articular damage to the subtalar joint with retrograde reaming. We hypothesized that reaming would destroy >50% of the posterior facet of the subtalar joint. The bilateral lower extremities of 5 cadavers were obtained and the subtalar joints exposed. Retrograde TTC nail guidewires were inserted, and a 12-mm reamer was passed through the subtalar and ankle joints. Pre- and postreaming images of the subtalar joint were obtained to compare the amount of joint destruction after reaming. We found an average of 5.89% articular destruction of the talar posterior facet and an average of 4.01% articular destruction of the posterior facet of the calcaneus. No damage to the middle facets of the subtalar joint was observed. TTC nailing is a successful procedure for ankle and subtalar joint fusion. Published studies have reported successful subtalar union using TTC nailing without formal open debridement of the subtalar joint, preserving the soft tissue envelope. TTC nail insertion using a 12-mm reamer will destroy 5.89% and 4.01% of the respective talar and calcaneal posterior facets of the subtalar joint.

    Pseudoangiomatous stromal hyperplasia (PASH), a rare benign lesion, shows the proliferation of the breast stromal tissue mimicking the low grade angiosarcoma (1-7). The most common mammographic and ultrasound finding of PASH is a circumscribed mass without calcification and it is difficult to distinguish from the phyllodes tumor and fibroadenoma (1-4, 8). Up to our knowledge, PASH presenting as rapid bilateral breast enlargement, as seen in our case, is very rare. In addition, several English medical literature were reported in this kind of manifestation of PASH (3, 4, 8). We described imaging findings of diffuse, infiltrating, and bilateral manifectation of PASH.

Plain films showed absence of thoracic pedicles bilaterally from T2 to T9, which was better demonstrated on CT multiplanar and 3-D reformatted images. There were no neurological symptoms even though the deformity progressed rapidly. Congenital kyphosis or kyphoscoliosis is often related to spinal anomalies that are located on the anterior aspect of the vertebrae.

    Full Text Available Meniere disease (MD is a heterogeneous clinical condition characterized by sensorineural hearing loss, episodic vestibular symptoms and tinnitus associated with several comorbidities such as migraine or autoimmune disorders (AD. The frequency of bilateral involvement may range from 5-50% and it depends on the duration of the disease. We have performed a two-step cluster analysis in 398 patients with bilateral MD to identify the best predictors to define clinical subgroups with a potential different etiology to improve the phenotyping of bilateral MD and to develop new treatments. We have defined five clinical variants in bilateral MD. Group 1 is the most frequently found, includes 46% of patients, and is defined by metachronic hearing loss without migraine and without AD. Group 2 is found in 17% of patients, and it is defined by synchronic hearing loss without migraine or AD. Group 3, with 13% of patients, is characterized by familial MD, while group 4, that includes 12% of patients, is associated by the presence of migraine in all cases. Group 5 is found in 11% of patients and is defined by AD. This approach can be helpful in selecting patients for genetic and clinical research. However, further studies will be required to improve the phenotyping in these clinical variants for a better understanding of the diverse etiological factors contributing to bilateral MD.

  2. Influence of flow variability on floodplain formation and destruction, Little Missouri River, North Dakota

    2009-01-01

    Resolving observations of channel change into separate planimetric measurements of floodplain formation and destruction reveals distinct relations between these processes and the flow regime. We analyzed a time sequence of eight bottomland images from 1939 to 2003 along the Little Missouri River, North Dakota, to relate geomorphic floodplain change to flow along this largely unregulated river. At the decadal scale, floodplain formation and destruction varied independently. Destruction was strongly positively correlated with the magnitude of infrequent high flows that recur every 5-10 yr, whereas floodplain formation was negatively correlated with the magnitude of frequent low flows exceeded 80% of the time. At the century scale, however, a climatically induced decrease in peak flows has reduced the destruction rate, limiting the area made available for floodplain formation. The rate of destruction was not uniform across the floodplain. Younger surfaces were consistently destroyed at a higher rate than older surfaces, suggesting that throughput of contaminants would have occurred more rapidly than predicted by models that assume uniform residence time of sediment across the floodplain. Maps of floodplain ages produced by analysis of sequential floodplain images are similar to maps of forest ages produced through dendrochronology, confirming the assumption of dendrogeomorphic studies that riparian tree establishment in this system is limited to recent channel locations. ?? 2009 Geological Society of America.

    1978-01-01

    An automatic hybrid holographic non-destructive testing (HNDT) method and system capable of detecting flaws or debonds contained within certain materials are described. This system incorporates the techniques of optical holography, acoustical/optical holography and holographic correlation in determining the structural integrity of a test object. An automatic processing system including a detector and automatic data processor is used in conjunction with the three holographic techniques for correlating and interpreting the information supplied by the non-destructive systems. The automatic system also includes a sensor which directly translates an optical data format produced by the holographic techniques into electrical signals and then transmits this information to a digital computer for indicating the structural properties of the test object. The computer interprets the data gathered and determines whether further testing is necessary as well as the format of this new testing procedure.

    1996-01-01

    We investigate the dynamical evolution of the Galactic Globular Cluster System in considerably greater detail than has been done hitherto, finding that destruction rates are significantly larger than given by previous estimates. More than half of the present clusters (52%-58% for the OC galactic model, and 75%-86% for the BSS model) will be destroyed in the next Hubble time. For the evolution of individual clusters we use a Fokker-Planck code including two-body relaxation, tidal truncation of clusters, compressive gravitational shocks while clusters pass through the Galactic disk, and tidal shocks due to passage close to the bulge. Gravitational shocks are treated comprehensively, using a recent result by Kundic & Ostriker (1995) that the shock-induced relaxation term, driving an additional dispersion of energies, is generally more important than the usual energy shift term. We discuss some implications for a past history of the Globular Cluster System, and the initial distribution of the destruction time...

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

    Laparoscopic adrenalectomy, if done by skilled surgeons, is now the first choice for treating most adrenal tumors, including bilateral pheochromocytoma. We report two women, aged 35 and 34 years old, with bilateral adrenal pheochromocytoma successfully excised by laparoscopic surgery. Both had severe hypertension, high urinary catecholamine values (epinephrine + norepinephrine: 528 and 1083 ug/24 h) and bilateral adrenal tumors at CT scan. After 4 weeks of doxazosin treatment, a laparoscopic transperitoneal adrenalectomy was done (Gugner's technique), with surgical times of 7 and 5 hours respectively. Both patients received hydrocortisone and only the second one required one unit of packed cells. Postoperative evolution was uneventful and both patients were discharged at the fifth postoperative day. At two months of follow up, both patients are asymptomatic and normotensive.

    Full Text Available A 39-year-old male was admitted to our clinic with symptoms of headache, dizziness, nausea, otalgia, otorrhea, tinnitus, and hearing loss in both ears for 3 weeks. Physical examination revealed edema in the tympanic membrane and external ear canal, and pain by palpation in the mastoid area bilaterally. There was no nystagmus, and the rest of the physical examination was otherwise normal. Temporal bone high resolution computed tomography (CT showed a lesion causing erosion in the mastoid cortex, tegmen tympani, ossicles, and in the bone covering the sigmoid sinus bilaterally. There was also erosion in the superior semicircular canal and petrous bone on the left side. Cortical mastoidectomy was performed under general anesthesia. Histopathologic examination of the tissue revealed Langerhans cell histiocytosis (LCH. In this paper a case with LCH, presenting with bilateral mastoid involvement which has been rarely reported in the literature, is discussed with the existing literature.

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

    Bilateral prophylactic mastectomy in women with increased breast cancer risk dramatically reduces breast cancer occurrence but little is known about psychosocial outcomes. To examine long-term quality of life after bilateral prophylactic mastectomy, we mailed surveys to 195 women who had the procedure from 1979 to 1999 and to a random sample of 117 women at increased breast cancer risk who did not have the procedure. Measures were modeled on or drawn directly from validated instruments designed to assess quality of life, body image, sexuality, breast cancer concerns, depression, health perception, and demographic characteristics. We used logistic regression to examine associations between quality of life and other domains. The response rate was 58%, with 106 women with and 62 women without prophylactic mastectomy returning complete surveys. Among women who underwent bilateral prophylactic mastectomy, 84% were satisfied with their decision to have the procedure; 61% reported high contentment with quality of life compared with an identical 61% of women who did not have the procedure (P = 1.0). Among all subjects, diminished contentment with quality of life was not associated with bilateral prophylactic mastectomy but with dissatisfaction with sex life (adjusted ratio [OR] = 2.5, 95% confidence interval [CI] = 1.0-6.2), possible depression (CES-D > 16, OR = 4.9, CI = 2.0-11.8), and poor or fair general health perception (OR = 8.3, 95% CI = 2.4-29.0). The majority of women reported satisfaction with bilateral prophylactic mastectomy and experienced psychosocial outcomes similar to women with similarly elevated breast cancer risk who did not undergo prophylactic mastectomy. Bilateral prophylactic mastectomy appears to neither positively nor negatively impact long-term psychosocial outcomes.

    2009-10-01

    Full Text Available During routine anatomical dissection of the infrahyoid region, a muscle was found bilaterally originating from the sternal end of clavicle and inserting into the hyoid bone. The muscle coursed parallel and lateral to the sternohyoid muscle. The muscle was found in the presence of an intact omohyoid, thus being classified as an accessory cleidohyoid (cleidohyoideus accessorius muscle. While other authors have reported the presence of a unilateral cleidohyoideus accessorius muscle, to our knowledge this is the first case of a bilateral cleidohyoideus accessorius muscle in the medical literature. Anatomical variations of the infrahyoid muscles may have functional, diagnostic, surgical and pathological implications.

    Choroidal osteoma is a an extremely rare (especially located bilaterally), benign, intraocular tumor, the type of choristoma. It occurs between 2-3 decades of life, women are particularly vulnerable. The main complication in 1/3 cases is a subretinal neovascularization which may cause bleeding. The gradually progressive decalcification develops within the tumour over time, which causes atrophy of the retinal pigment epithelium and Bruch's membrane deformity. The article presents a case of a 26-year-old woman with bilateral choroidal osteoma complicated by subretinal hemorrhage; the diagnosis was based on clinical examination (biomicroscopy and indirect ophthalmoscopy) as well as specialised tests including: ultrasonography, optical coherence tomography, and fluorescein angiography.

    Highlights: • The first wall of F82H steel will be fabricated by the HIP method. • Inspection techniques need to be developed for the HIPed interface. • Both destructive and non-destructive inspection techniques are introduced. - Abstract: The first walls of F82H steel with built-in cooling channels will be assembled thin plates and rectangular pipes by a HIP method. Silicon oxides form on an interface of HIPed joints during HIPing and result in the lowering of toughness of the HIPed joints. A large issue is investigation method of HIPed interface. The flexibility of specimen size for the investigation will be necessary because of the thin wall of cooling channels. A small specimen destructive test technique which is able to distinguish a base metal and an excellent HIPed joint has been desired, and recent researches find out a torsion test method to solve the issue. Non-destructive test technique is another issue for the inspection of the first wall. An ultrasonic inspection method is a candidate but silicon oxides are too small to produce good flaw echo from oxides, some solutions will be necessary. Present research introduces the current status of development of small specimen destructive test technique and the ultrasonic method for the first wall inspection.

    Recent reports have shown the existence of subchondral insufficiency fracture in rapidly destructive arthrosis of the hip joint (RDA), and the findings suggest that osteopenia is related to the pathogenesis of the rapid progression of this disease. Therefore, we measured bone mineral density (BMD) in RDA patients. We measured BMD of the lumbar spine, radius, and calcaneus using dual-energy X-ray absorptiometry in 19 patients with RDA and 75 with osteoarthritis of the hip (OA) and compared BMD at different skeletal sites between RDA and OA patients. No significant differences were observed in BMD of the lumbar spine, ultradistal radius, mid-radius, and calcaneous between the RDA and OA groups. Our data suggest that RDA is not accompanied by generalized osteoporosis. Factors other than generalized bone status, for example, BMD around the affected hip joint before destruction, need to be analyzed to elucidate the pathophysiological mechanism of RDA.

    A 48-year-old smoker with a history of hyperthyroidism treated 10 years prior to presentation with radioactive iodine ablation of the thyroid gland presented to his ophthalmologist with a 2-week history of transient loss of vision in the right eye occurring for 1 to 2 hours each morning. He denied ocular pain, diplopia or change in the prominence of one or both eyes. Examination revealed 2 mm of relative proptosis on the right, bilateral temporal flare and lower lid retraction. There was minimal upper lid retraction and no evidence of lid lag. Ocular motility was full. Dilated fundoscopic examination revealed bilateral optic nerve edema, right more than left. CT of the orbit demonstrated enlargement of the extraocular muscles bilaterally with marked enlargement of the right medial rectus and left inferior rectus muscles resulting in crowding at the orbital apex bilaterally. Laboratory testing revealed the patient to be hyperthyroid. The patient was treated with high dose oral steroids followed by orbital radiation. Hyperthyroidism was managed by the patient's primary care physician. Visual symptoms rapidly improved with oral steroids and orbital radiation. Optic nerve edema completely resolved. Repeat CT imaging demonstrated a reduction in the enlargement of the extraocular muscles with relief of bilateral optic nerve compression.

    Full Text Available Objective of our study was to increase the effectiveness of surgical treatment of bilateral destructive pulmonary tuberculosis complicated by pleural empyema by using VTS-technologies. The study was done in Dnepropetrovsk regional clinical therapeutic and prophylactic association "Phthisiology" in the period from 2008 to 2013. A retrospective analysis of 43 cases of bilateral destructive pulmonary tuberculosis complicated by pleural empyema on one side and dissemination focus or limited destructive process on contralateral side has been performed. Selected cases were divided into 2 groups: main (eighteen cases where the following procedures were done: performed transsternal occlusion of the main bronchus, sanation of empyema cavity using videothoracosopy, in 30-45 days followed by pleuropneumectomy with usage of minithoracothomy and control (nineteen cases who had undergone drainage of the empyema cavity, sanation, in 45-60 days followed by pleuropmeumectomy with usage of anterolateral access. The distribution of main and control groups for analyzed parameters was representative. Sanation of pleural cavity with videothoracosopy usage compared with Bulau’s drainage provides better antibacterial effect, effective sanitation of the pleural cavity as evidenced by following changes: significant decrease in the number of microbial cells; normalization of total white blood cells count and rod-shaped granulocytes in the peripheral blood 10 days after treatment; normalization of leukocyte intoxication index. The use of minimally invasive surgical treatment allowed to reduce intraoperative complications by 2 times, amount of intraoperative blood loss and hemotrasfusions by 1.5 times, postoperative mortality by 2.5 times. Pleural cavity sanation with videothoracoscopy usage with following pneumoectomy leads to reduce in the incidence and severity of postoperative complications. The most promising is stage-by-stage surgical approach with consecutive use

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

  20. Fast and Provably Accurate Bilateral Filtering.

    Science.gov (United States)

    Chaudhury, Kunal N; Dabhade, Swapnil D

    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 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 the state-of-the-art methods in terms of speed and accuracy.

    2014-07-01

    Full Text Available Extrapontine myelinolysis (EPM is a rare clinical entity affecting anterior basal ganglia. This is one of the osmotic demyelination syndromes. It occurs due to rapid correction of hyponatremia and also rarely occurs in alcoholics. It generally presents with extrapyramidal symptoms. We here report a case of EPM in a 13 year old boy presenting with bilateral internuclear ophthalmoplegia and ptosis. The patient also had generalised weakness, but no psychiatric symptoms. The patient slowly recovered over six months. EPM can affect any age group, although the elderly are more likely to be affected due to frequent electrolyte abnormalities. Ocular movement disorders or brainstem signs are rarely reported in EPM. When present, it can create diagnostic confusion with multiple sclerosis. We believe this is the first report of this entity from India. The relevant literature regarding brainstem manifestations in myelinolysis syndromes is also discussed, along with the radiological findings.

  6. Experimentally Evaluated Explosion Resistance and Performance of Destruction Unit in Multiple Detonation of Ammunition

    2016-01-01

    Full Text Available The paper presents results of development and experimental investigation of explosion resistance and destruction unit performance in multiple detonation of ammunition with an explosive weight up to 0.7 kg of TNT. A preliminary evaluation of the explosion resistance was carried out using a model of explosion resistance localizer, represented as a thick-walled tube. As a result of explosive tests, the nature and characteristics of tube deformation under repeated explosions have been revealed. The findings allowed us to develop the first embodiment of the destruction unit with a turning non-separable heater and a two-layer localizer, which was heated by the induction field. The explosive life tests have revealed the following drawbacks: low resource localizer, jamming rotating mechanism in contact with the splinters, and impossible replacement of damaged localizer. In the second embodiment of the destruction unit a plate-assembled easychange localizer is mounted on the heater, and it is heated by heat transfer from the core. Tests have shown that, with such a placement, the uniform heating of the localizer is not reached. This leads to incomplete destruction of ammunition. Besides, because of the low strength of the pins connecting the plates, occurrs their rapid destruction. Taking into consideration the shortcomings of the previous two designs, the third option of the destruction unit with a replaceable localizer and induction heating of a localizer has been designed. A localizer material having high mechanical strength at high temperatures and good ferromagnetic properties has been selected. The paper offers an all-metal localizer design with the thickest wall at the bottom that is the most damageable. The paper has experimentally determined a critical deformation of the localizer when destroying the ammunition with varying weight of explosive and defined the heater and bump resource. As a result, the work proposes the destruction unit design

    1999-10-01

    The first 100 T non-destructive (100 T ND) magnet and power supplies as currently designed are described. This magnet will be installed as part of the user facility research equipment at the National High Magnetic Field Laboratory (NHMFL) Pulsed Field Facility at Los Alamos National Laboratory. The 100 T ND magnet will provide a 100 T pulsed field of 5 ms duration (above 90% of full field) in a 15 mm diameter bore once per hour. Magnet operation will be non-destructive. The magnet will consist of a controlled power outer coil set which produces a 47 T platform field in a 225 mm diameter bore. Located within the outer coil set will be a 220 mm outer diameter capacitor powered insert coil. Using inertial energy storage a synchronous motor/generator will provide ac power to a set of seven ac-dc converters rated at 64 MW/80 MVA each. These converters will energize three independent coil circuits to create 170 MJ of field energy in the outer coil set at the platform field of 47 T. The insert will then be energized to produce the balance of the 100 T peak field using a 2.3 MJ, 18 kV (charged to 15 kV), 14.4 mF capacitor bank controlled with solid-state switches. The magnet will be the first of its kind and the first non-destructive, reusable 100 T pulsed magnet. The operation of the magnet will be described along with special features of its design and construction.

    1983-02-01

    Twenty percent of a population of mentally retarded children, who underwent clinical observation because of behavior problems, demonstrated serious aggressive, destructive, negativistic and hyperactive behavior patterns. According to the parents this type of behavior developed between two and four years of age. It remains unclear whether this behavior is caused by a differential rate of maturation of certain brain structures or by unfavorable emotional and environmental variables. A psychotherapeutic approach to the treatment of these children led to positive results. It is supposed that if left untreated, a symptom shift can occur towards neurotic, depressive or aggressive behavior when the child gets older.

A flowsheet is established for the recommended technology.

  11. Constraining Tidal Dissipation in Stars and Destruction Rates of Exoplanets

    Science.gov (United States)

    Jackson, Brian; Penev, K.; Barnes, R.

    2011-01-01

    Several recent studies have shown that the orbits of most transiting extra-solar planets, with periods of order a few days, are not stable against tidal decay. If the host star rotates slowly enough, tidal dissipation within the star causes the planet to spiral in over many millions or billions of years. Because the rate of tidal decay increases rapidly as orbital semi-major axis drops, planets that start out very close to their host stars are quickly destroyed, while planets farther out require more time. We calculate the times left for known transiting exoplanets as a function of the rate of tidal dissipation within the host star. For a population of such planets, we expect to observe a minority of planets near the end of their lives since those planets will only survive for a short time more. For an assumed tidal dissipation rate, if we find instead that a majority of transiting planets have only a small fraction of the lifetimes left before destruction, we can conclude the assumed tidal dissipation rate is too large. Thus, we can estimate the rate of tidal dissipation within planet-hosting stars by considering the distributions of times left of transiting planets for a range of assumed dissipation rates. We must also account for important selection and observational biases. Our results based on such an analysis suggest stellar dissipation rates corresponding to tidal Q-values of 106 and larger are consistent with observations, while values of 105 and smaller are not. Given these constraints, we estimate the rates of tidal destruction of transiting exoplanets.

    Supercritical water oxidation is a relatively low-temperature process that can give high destruction efficiencies for a variety of hazardous chemical wastes. Results are presented examining the destruction of high explosives and propellants in supercritical water and the use of low temperature, low pressure hydrolysis as a pretreatment process. Reactions of cyclotrimethylene trinitramine (RDX), cyclotetramethylene tetranitramine (HMX), nitroguanidine (NQ), pentaerythritol tetranitrate (PETN), and 2,4,6-trinitrotoluene (TNT) are examined in a flow reactor operated at temperatures between 400{degrees}C and 650{degrees}C. Explosives are introduced into the reactor at concentrations below the solubility limits. For each of the compounds, over 99.9% is destroyed in less than 30 seconds at temperatures above 600{degrees}C. The reactions produce primarily N{sub 2}, N{sub 2}O,CO{sub 2}, and some nitrate and nitrite ions. The distribution of reaction products depends on reactor pressure, temperature, and oxidizer concentration. Kinetics studies of the reactions of nitrate and nitrite ions with various reducing reagents in supercritical water show that they can be rapidly and completely destroyed at temperatures above 525{degrees}C. The use of slurries and hydrolysis to introduce high concentrations of explosives into a supercritical water reactor is examined. For some compounds the rate of reaction depends on particle size. The hydrolysis of explosives at low temperatures (<100{degrees}C) and low pressures (<1 atm) under basic conditions produces water soluble, non-explosive products which are easily destroyed by supercritical water oxidation. Large pieces of explosives (13 cm diameter) have been successfully hydrolyzed. The rate, extent, and products of the hydrolysis depend on the type and concentration of base. Results from the base hydrolysis of triple base propellant M31A1E1 and the subsequent supercritical water oxidation of the hydrolysis products are presented.

    We report a case of a 55-year-old man with ischemic lesions of the bilateral hippocampus and bilateral basal ganglia following a myocardial infarction during an episode of multiple drug use with subsequent anoxia requiring resuscitation. He presented for a neuropsychological evaluation with an anterograde amnesia for both explicit and procedural memory. There are two main points to this case, the unique aspects of the bilateral multifocal lesions and the functional, cognitive impact of these lesions. We hypothesize that his rare focal bilateral lesions of both the hippocampus and basal ganglia are a result of anoxia acting in synergy with his stimulant drug use (cocaine and/or 3,4-methylenedioxy-methamphetamine). Second, his unique lesions produced an explicit and implicit/procedural anterograde amnesia. PMID:28228745

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

    2015-01-01

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

    Pyelonephritis is defined as an inflammation of the kidney and renal pelvis. The diagnosis is usually clinical. Acute multifocal bacterial nephritis is a rare form of pyelonephritis that is more severe and sepsis is more common. We report a patient who presented with fever and right-sided abdominal pain associated with right flank tenderness, suggesting right acute pyelonephritis. Bilateral multifocal pyelonephritis was diagnosed on ultrasonography, radionuclide renal scintigraphy and computed tomography. However, owing to non-resolution of symptoms, a biopsy was performed, which showed bilateral papillary renal cell carcinoma (PRCC). PRCC is known to exhibit multicentricity. To our knowledge, a case of bilateral multicentric PRCC masquerading as bilateral multifocal pyelonephritis has not been reported in the English literature. This case highlights the need to be vigilant while treating patients with focal lesions of the kidney as an inflammatory condition lest a malignancy should be missed.

    Five patients aged 55 to 73 years (mean 63 years) underwent one-stage clipping for unruptured aneurysms in the bilateral middle cerebral arteries (mean size 4.5 mm, range 2 to 7 mm) via the bilateral pterional keyhole approach in our institute. Important points are as follows: the head is affixed with no rotation; one side manipulation is started 5 minutes after the other side to avoid conflict of surgical instruments; a 5-cm curvilinear skin incision is made inside the hairline and pterional keyhole craniotomy is made bilaterally using 2 burr holes; the whole operating table is rotated 15 degrees to one side to facilitate the microsurgical trans-sylvian approach and aneurysm clipping; the operating table is rotated to the other side for the contralateral procedure; and particular care is taken to avoid bilateral brain injury. This approach provided minimum but sufficient working space required for trans-sylvian dissection. Aneurysm neck clipping was safely performed in a mean operation time of 5 hours 17 minutes. No complications occurred and satisfactory cosmetic results were obtained in all patients. Postoperative neuroimaging studies exhibited bilateral complete clipping with minimal intracranial air content and minimum consequences of brain retraction. One-stage clipping via the pterional keyhole approach is a safe and effective therapeutic option for small bilateral aneurysms.

    We perform smoothed particle hydrodynamics (SPH) simulations of an isolated galaxy with a new treatment for dust formation and destruction. To this aim, we treat dust and metal production self-consistently with star formation and supernova feedback. For dust, we consider a simplified model of grain size distribution by representing the entire range of grain sizes with large and small grains. We include dust production in stellar ejecta, dust destruction by supernova (SN) shocks, grain growth by accretion and coagulation, and grain disruption by shattering. We find that the assumption of fixed dust-to-metal mass ratio becomes no longer valid when the galaxy is older than 0.2 Gyr, at which point the grain growth by accretion starts to contribute to the nonlinear rise of dust-to-gas ratio. As expected in our previous one-zone model, shattering triggers grain growth by accretion since it increases the total surface area of grains. Coagulation becomes significant when the galaxy age is greater than $\\sim$ 1 Gyr: a...

    Pyogenic granuloma is a overzealous proliferation of a vascular type connective tissue as a result of some minor trauma and is a well circumscribed elevated, pedunculated or sessile benign inflammatory lesion of skin and mucous membrane. The clinical features of pyogenic granuloma are indicative but not specific and nearly all cases of pyogenic granulomas are superficial in nature, and there is little if any mention in the literature of these lesions producing alveolar bone even jaw bone loss. This case is somewhat unique in that the lesion was an obvious histologic pyogenic granuloma; however, it appeared to invade the mandibular bone which resulted in the loss of the adjacent teeth. A 12-year-old boy came to Seoul National University Dental Hospital with chief complaints of left facial swelling. The features obtained were as follows ; Plain radiograms showed a large well-circumscribed radiolucent lesion on left mandibular ramus area, which made severe expansion of lingual cortex and displacement of lower left 3rd molar tooth germ. Computed tomograms showed large soft tissue mass involving left masticator space with destruction of left mandibular ramus. Histologically, sections revealed loose edematous stroma with intense infiltration of inflammatory cells and proliferation of vascular channels. Also, there were focal areas of extensive capillary proliferation, bone destruction and peripheral new bone formation.

    Koza, Y.; Amouroux, S.; Bazylev, B. N.; Berthe, E.; Kuehnlein, W.; Linke, J.; Penkalla, H. J.; Singheiser, L.

    Erosion mechanisms for different carbon based materials (graphite, carbon fiber composites (CFCs), Si-doped CFC) have been studied under brittle destruction under intense transient thermal loads (ELMs, plasma disruptions, VDEs) with respect to material erosion in different particle emission regimes, characterization of emitted particles, and behavior of preheated samples. Furthermore, the experimental data were compared with 3-D numerical simulation on the onset of brittle destruction. From a morphological point of view, the resulting erosion patterns on the test samples and ejected particles differ significantly for the three materials. The isotropic graphite shows a homogeneous erosion profile with flat craters, while the CFC forms no crater and only preferential erosion in localized spots in the PAN fiber area while the pitch fiber strands remain almost undamaged. The particles originating from graphite samples which have been collected on TEM grids are composed of nano sized amorphous carbon. CFCs have been the source for sub Î 1/4 m sized agglomerated fragments of crystalline carbon or silicon particles with âe 1/4 50 nm diameter. Preheating of the test samples to 500 or 800°C results in a remarkable increase of the erosion depth and weight loss compared to the samples loaded at room temperature and identical heat fluxes. In particular, melting phenomena in the Si-doped CFC materials became essential at elevated temperatures.

    The use of non-destructive evaluation (NDE) for defect detection and failure prediction in structures and specimens is widespread in energy industries, aimed at ageing power plants and pipelines, material degradation, fatigue and radiation damage, etc. At present there are no suitable electromagnetic NDE methods for the measurement and characterization of material degradation, in irradiated samples in particular, which is very important and timely for the nuclear power industry in the UK. This paper reports recent developments in the field of electromagnetic (EM) NDE at Newcastle University, including pulsed eddy current (PEC), pulsed magnetic flux leakage (PMFL), magnetic Barkhausen emission (MBE) and magneto-acoustic emission (MAE). As different EM methods have different strengths, an integrative EM framework is introduced. Case studies through the second round robin tests organized by the Universal Network for Magnetic Non-Destructive Evaluation (UNMNDE), representing eighteen leading research groups worldwide in the area of electromagnetic NDE, are reported. Twelve samples with different ageing times and rolling reduction ratios were tested using different magnetic methods among the UNMNDE members. Based on the studies, the complementary characteristics of electromagnetic techniques for NDE are discussed.

    2008-07-30

    The 200 Area Effluent Treatment Facility (ETF) main treatment train includes the peroxide destruction module (PDM) where the hydrogen peroxide residual from the upstream ultraviolet light/hydrogen peroxide oxidation unit is destroyed. Removal of the residual peroxide is necessary to protect downstream membranes from the strong oxidizer. The main component of the PDM is two reaction vessels utilizing granular activated carbon (GAC) as the reaction media. The PDM experienced a number of operability problems, including frequent plugging, and has not been utilized since the ETF changed to groundwater as the predominant feed. The unit seemed to be underperforming in regards to peroxide removal during the early periods of operation as well. It is anticipated that a functional PDM will be required for wastewater from the vitrification plant and other future streams. An alternate media or methodology needs to be identified to replace the GAC in the PDMs. This series of bench scale tests is to develop information to support an engineering study on the options for replacement of the existing GAC method for peroxide destruction at the ETF. A number of different catalysts will be compared as well as other potential methods such as strong reducing agents. The testing should lead to general conclusions on the viability of different catalysts and identify candidates for further study and evaluation.

    2012-01-01

    Full Text Available Simultaneous bilateral spontaneous pneumothorax (SBSP and pneumomediastinum are complications rarely observed synchronously during an acute asthma attack. It is a clinical condition that manifests itself with serious respiratory distress and must be rapidly diagnosed and treated. Although bilateral spontaneous pneumothorax has already been reported in asthma patients in the literature, its concurrence with subcutaneous emphysema and pneumomediastinum is extremely rare except for iatrogenic conditions. By sharing this case about a 39-year-old patient who presented to the emergency room with severe respiratory distress and developed cardiopulmonary arrest during his physical examination, our aim is to emphasize that a rapid diagnosis and treatment by the emergency physicians is the only way for survival in these patients.

    A 49-year-old female victim of violent crime with an acute bilateral loss of vision was referred to our hospital. The ophthalmological evaluation showed complete subconjunctival hemorrhage of both eyes, bilateral hemophthalmos and hypotonia of the left eye. These raised the suspicion of an occult scleral rupture. We immediately performed exploratory surgery and found a perforating scleral lesion of the left eye and a penetrating scleral lesion of the right eye. Furthermore, a small, cruciform wound was detected on the left temple. In cooperation with the department of radiology, the extraordinary injury pattern was reconstructed: a horizontal stab wound with perforation of the left eye and penetration of the right eye caused by a screwdriver. Visual rehabilitation necessitated further surgical interventions. Besides the intraoperative approach, immediate primary wound management within 100 h of trauma plays a pivotal role for long-term outcome.

    Full Text Available 【Abstract】There is a dearth of case reports de-scribing simultaneous bilateral patellar tendon ruptures in the medical literature. These ruptures are often associated with systemic disorders such as lupus erythematosus or chronic steroid use. The author describes a case of a 24-year-old man who sustained traumatic bilateral patellar ten-don ruptures without any history of systemic disease or steroidal medication. We repaired and reattached the rup-tured tendons to the patella and augmented our procedure with allogeneic tendon followed by wire loop reinforcement. One year after operation, the patient regained a satisfactory range of motion of both knees with good quadriceps strength and no extensor lag. The recurrent microtrauma from a history of intense sports activity and a high body mass index may have played an important role in this trauma event.

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

    Two experiments examined the effect of illusion of control on in-group favoritism found in the minimal group situation (Tajfel, Billig, Bundy, & Flament, 1971). In bilateral dependency condition, each member made allocation decisions for in-group as well as out-group participants. It was exactly the same situation used in the original studies under the minimal group paradigm, and the subjects knew that their reward allocation too depended on others' decisions. In contrast, in unilateral dependency condition, the subjects made allocation decisions knowing that theirs were not dependent on others' decisions. In Experiment 1, an in-group bias in reward distribution was found in the bilateral dependency condition, but not in the unilateral condition. In Experiment 2, it was found that only those who felt illusion of control exhibited such an in-group bias. Results of the experiments therefore confirmed that illusion of control explained in-group favoritism, as Karp, Jin, Yamagishi, and Shinotsuka (1993) originally hypothesized.

    This case study describes a 37-year-old male who suffered a bilateral transverse acetabulum fracture with a fracture of the posterior wall and a double-sided dorsal hip dislocation in combination with a left-sided femoral head fracture (Pipkin IV) while skiing in a "fun park". The accurate diagnosis and presurgical planning was made by means of a computed tomography (CT) scan and a subsequent 3D reconstruction. After a primarily executed shielded repositioning of the bilateral hip dislocationearly secondary and anatomical reconstruction of the double-sided acetabulum fracture was possible using the Kocher-Langenbeck approach. A consistent physiotherapy as well as rehabilitation finally led to a positive clinical result for the patient.

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

    A 53-year-old woman presented with a complaint of a sore throat. Examination showed a left-sided atrophy of the tongue. Upon protrusion, the tongue deviated to the left, suggestive of a unilateral hypoglossal nerve palsy. Computed tomography revealed enlarged hypoglossal canals. Magnetic resonance imaging (MRI) demonstrated bilateral hypoglossal canal masses, with enhancement following gadolinium administration. Magnetic resonance angiography and MRI with fat suppression revealed nonvascular masses in both hypoglossal canals. Radiological diagnosis of bilateral hypoglossal nerve schwannoma was made and the patient was scheduled for MRI monitoring with six-month intervals. The size of the masses and the clinical manifestations remained unchanged during a two-year follow-up period.

    Women who develop bilateral breast cancer at an early age are likely to harbour germline mutations in breast cancer susceptibility genes. The aim of this study was to test for concordant genetic changes in left and right breast cancer of young women (age < 50) with bilateral breast cancer that may suggest an inherited breast cancer predisposition. Microsatellite markers were used to test for loss of heterozygosity (LOH) in left and right tumours for 31 women with premenopausal bilateral breast cancer. Markers adjacent to or within candidate genes on 17p (p53), 17q (BRCA1), 13q (BRCA2), 11q (Ataxia Telangiectasia-ATM) and 3p (FHIT) were chosen. Mutational testing for BRCA1 and BRCA2 was performed for cases where blood was available. Concordant LOH in both left and right tumours was demonstrated for at least one of the markers tested in 16/31(54%) cases. Where allelic loss was demonstrated for both left and right breast cancer, the same allele was lost on each occasion. This may suggest a common mutational event. Four cases showed concordant loss of alleles in both left and right breast cancer at D17S791 (BRCA1). BRCA1 mutations were identified in two of these cases where blood was available. Four cases showed concordant LOH at D13S155 (BRCA2). Concordant LOH was further demonstrated in seven cases for D11S1778 (ATM) and four cases for D3S1300 (which maps to the FHIT gene), suggesting a possible role for these tumour suppressor genes in this subgroup of breast cancer patients. No concordant allelic loss was demonstrated for D17S786 suggesting that germline mutations in p53 are unlikely in such cases of bilateral breast cancer.

    Germinoma arising in the bilateral basal ganglia is exceedingly rare, with only five cases reported to date. Owing to non-specific clinical findings and the frequent presence of ill-defined abnormalities without a definite tumor mass on neuroimaging, the diagnosis can be difficult. We describe a case in which magnetic resonance spectroscopy (MRS) findings suggested a tumor and supported the decision to perform biopsy of the lesion.

    Brodie's abscess is a form of subacute osteomyelitis, which typically involves the metaphyses of the long tubular bones, particularly in the tibia. The diagnosis is usually made incidentally, as there are no accompanying symptoms or laboratory studies. Bilateral involvement at the proximal tibia is unusual. However, orthopaedic surgeons should be aware of this entity, as it may present without symptoms. Checking the contralateral limb for concomitant Brodie's abscess is recommended.

    2010-01-01

    At space vehicle launch sites such as Vandenberg Air Force Base (VAFB), Cape Canaveral Air Force Station (CCAFS) and Kennedy Space Center (KSC), toxic vapors and hazardous liquid wastes result from the handling of commodities (hypergolic fuels and oxidizers), most notably from transfer operations where fuel and oxidizer are transferred from bulk storage tanks or transfer tankers to space launch vehicles. During commodity transfer at CCAFS and KSC, wet chemical scrubbers (typically containing four scrubbing towers) are used to neutralize fuel saturated vapors from vent systems on tanks and tanker trailers. For fuel vapors, a citric acid solution is used to scrub out most of the hydrazine. Operation of both the hypergolic fuel and oxidizer vapor scrubbers generates waste scrubber liquor. Currently, scrubber liquor from the fuel vapor scrubber is considered non-hazardous. The scrubber liquor is defined as spent citric acid scrubber solution; the solution contains complexed hydrazine I methylhydrazine and is used to neutralize nonspecification hypergolic fuel generated by CCAFS and KSC. This project is a collaborative effort between Air Force Space Command (AFSPC), Space and Missile Center (SMC), the CCAFS, and National Aeronautics and Space Administration (NASA) to evaluate microwave destruction technology for the treatment of non-specification hypergolic fuel generated at CCAFS and KSC. The project will capitalize on knowledge gained from microwave treatment work being accomplished by AFSPC and SMC at V AFB. This report focuses on the costs associated with the current non-specification hypergolic fuel neutralization process (Section 2.0) as well as the estimated costs of operating a mobile microwave unit to treat non-specification hypergolic fuel (Section 3.0), and compares the costs for each (Section 4.0).The purpose of this document is to assess the costs associated with waste hypergolic fuel. This document will report the costs associated with the current fuel

    Breast cancer is the most common malignancy in women. The most frequent metastatic sites are lung, bone, liver and brain. On the other hand, gastric metastases are rare. Synchronous bilateral breast cancer (SBBC) occurs rarely. Lobular carcinoma is the histological type most often associated with bilateral breast carcinomas and gastric metastases. We made a retrospective study including four patients followed in the Salah Azaiez Institute, for a bilateral breast cancer with gastric metastases. We analyzed the epidemiological, anatomoclinical and therapeutic particularities of this rare entity. Symptoms were unspecific. The diagnosis of gastric metastasis of the SBBC was confirmed by a histopathological examination of an endoscopic biopsy. The median age was 46.2 years (range, 36–51 years) and the median time until the gastric involvement was 19 months (range, 0–41 months). None of patients had a surgical treatment for the gastric location. All Patients received at least one line of chemotherapy and radiotherapy. Median survival following the detection of gastric involvement was 22 months (range, 1–56 months). Gastric metastases from breast cancer are rare and frequently associated with other distant metastasis. Symptoms are unspecific and endoscopy may not be contributive. Therefore, gastric involvement is underestimated. Lobular infiltrating carcinoma (LIC) is the most histological type incriminated in its occurrence. The supply of immunohistochemistry is crucial to distinguish between primary or metastatic gastric cancer. PMID:28280631

    2008-06-05

    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.

    Full Text Available Nasolabial cysts are painless, submucosal, non-odontogenic jaw cysts presenting as soft tissue swellings in the maxillary anterior mucolabial fold lateral to midline, leading to elevation of nasal ala. Present case documents bilateral nasolabial cysts in a 69-year-old Asian female patient. In the present case, extraoral swelling of maxillary lip and elevation of nasal ala was observed on right side of the face. Intraorally, soft and fluctuant bilateral cysts were observed. Straw-colored fluid was aspirated from the right cyst. Radiographically, erosion of bone in a "cupping" fashion was observed in the region of left cyst. The cysts were enucleated using intraoral approach. Histopathology of the right-sided cyst revealed a cystic cavity lined by stratified squamous cells along with a few mucosal cells. At few places, stratified squamous and pseudostratified columnar epithelia with many cilia and goblet cells were also evident. Capsule was loosely arranged with fibrous tissue and chronic inflammatory infiltrate. Left-sided cystic specimen showed two or more layered stratified squamous lining epithelium with thin capsule. Diagnosis of bilateral nasolabial/nasoalveolar cysts was confirmed.

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

    2014-12-01

    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.

    Full Text Available Abstract Introduction We report a case of bilateral herpetic keratitis developing after rapid oral corticosteroid tapering in a patient with pemphigus foliaceus, which was followed by unilateral neurotrophic keratitis that was treated with amniotic membrane transplantation. Case presentation A 71-year-old Korean man developed bilateral herpetic keratitis one week after rapid tapering of systemic corticosteroid. He had been on high-dose oral corticosteroid and azathioprine therapy for six months for treatment of pemphigus foliaceus. Topical acyclovir ointment was prescribed. A week later, our patient's right eye had healed, but his left eye showed increased stromal edema with enlarged epithelial defects. He was prescribed oral acyclovir with topical broad-spectrum antibiotics applied to his left eye. The stromal edema cleared within a week but the epithelial defect remained unchanged. An amniotic membrane transplantation was performed on our patient's left eye, and his epithelial defect had totally healed three weeks later. Conclusions Patients with autoimmune disease or who are on immunosuppressive therapy have a higher chance of developing bilateral herpetic keratitis. Although rare, the condition may be followed by unilateral neurotrophic keratitis. Rapid corticosteroid tapering may act as a triggering factor for viral infection or reactivation of herpes.

    Rapidly destructive hip disease is a rare condition, the cause of which is yet to be clarified, and is described in the literature by scant case reports. The disease was first described by Forestier in 1957, and since then many names have been proposed to describe the rapid vanishing of the femoral head, and occasionally the acetabulum. This condition initially represents as acute hip pain, and rapidly progresses to complete vanishing of the proximal femur, within a few months. We briefly discuss the literature regarding this phenomenon, and describe a case of a female patient who suffered from complete disappearance of the femoral head within 9 weeks.

    In this summary, we have shown that diodes are susceptible to destructive single-event effects, and that these failures occur along the guard ring. By determining the last passing voltages, a safe operating area can be derived. By derating off of those values, rather than by the rated voltage, like what is currently done with power MOSFETs, we can work to ensure the safety of future missions. However, there are still open questions about these failures. Are they limited to a single manufacturer, a small number, or all of them? Is there a threshold rated voltage that must be exceeded to see these failures? With future work, we hope to answer these questions. In the full paper, laser results will also be presented to verify that failures only occur along the guard ring.

We demonstrate that the technique is capable of imaging a small sample of only 10 4 atoms up to 100 times with negligible decreases in atom number and no observable heating. At approximately 1GHz detuning, the SNR remains at approximately 7 for all 100 images, with a 22ms TOF absorption image confirming the survival of the condensate. The splitting of the magnetic sublevels of this species at such fields show non-trivial selection rules. We present experimental data outlining particular allowed transitions in this regime.

    2014-06-01

    Full Text Available This paper is a survey of the destruction of books particularly by traditionists (collectors, transmitters, and critics of hadith and particularly in the ninth century CE and before, offered as an addendum to Omar Ali de Unzaga’s forthcoming study of book burning in Islam. The destruction of books from distrust of written transmission has been adequately brought out by Michael Cook. What I chiefly add to previous scholarly accounts are some additional examples, a brief consideration of destroying books for the sake of orthodoxy, and a better account of pious reasons for destroying books, which had much to do with distrust not of writing hadith but of teaching it as a temptation to pride and a distraction from weightier things.Este artículo ofrece una panorámica de la destrucción de libros especialmente por parte de los tradicionistas (compiladores, transmisores, críticos del hadiz, especialmente en el siglo IX de la era cristiana y antes, que sirve como una adenda al estudio (en curso de publicación de Omar Ali de Unzaga sobre la quema de libros en el islam. La destrucción de libros a causa de la desconfianza hacia la transmisión escrita ha sido analizada en profundidad por Michael Cook. Lo que me interesa añadir a la investigación previa son algunos ejemplos adicionales, unas breves consideraciones sobre la destrucción de libros en pro de la ortodoxia, y una mejor presentación de las razones piadosas para destruir libros, razones que tenían mucho que ver con la desconfianza no tanto de poner escrito el hadiz, sino de enseñarlo, en tanto que tentación para caer en la vanidad y distracción de asuntos más importantes.

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

  11. Bilateral periprosthetic stress fractures in a juvenile chronic arthritis patient secondary to bilateral genu valgum.

    Science.gov (United States)

    Al-Khateeb, H; Meir, A; Singer, G C

    2007-01-01

    Lateral insufficiency fractures following total hip replacement have been reported with the femoral stems positioned in varus, together with osteopenia of the lateral femoral cortex. Any abnormal alignment of the lower limbs, such as genu valgum, will alter the load distribution across the femoral cortices, and repetitive loading during walking will predispose the bones to stress fractures at any stress riser point, such as the tip of a femoral component. Bilateral femoral stress fractures post total hip replacements have not been previously described. We present a 55-year-old woman, diagnosed with juvenile idiopathic arthritis, who had undergone bilateral total hip replacements and bilateral knee replacements. The knees 15 years postoperatively were in valgus and the left knee was extremely stiff, flexing to just 5. The patient presented with bilateral thigh pain, with plain radiographs confirming bilateral periprosthetic fractures of the femur at the tip of well-fixed femoral components. There was no history of injury and her hips were functioning well up to this time. The patient required revision of both hips to long-stem uncemented components, bypassing the fractures, and revision of both knees to stemmed semi-constrained implants, thereby correcting the alignment of both lower limbs. Both fractures healed and the patient is currently pain-free and mobile with walking aids. Surgeons must remain aware that when implants are in situ, abnormal alignments will lead to abnormal forces, and stress fractures are likely to occur at any stress riser around the implant. Avoiding malalignment will avoid this complication.

    The mechanism of a rise in blood pressure after kidney irradiation is unclear but most likely of renal origin. We have investigated the role of the renin-angiotensin system and dietary salt restriction in the development of systolic hypertension after bilateral kidney irradiation in young and adult rats. Three to 12 months after a single X-ray dose of 7.5 or 12.5 Gy to both kidneys of young and adult rats, the systolic blood pressure (SBP) and plasma renin concentration (PRC) were measured regularly. A single X-ray dose of 12.5 Gy caused a moderate rise in SBP and a slight reduction in PRC in both young and adult rats. A dose of 7.5 Gy did not significantly alter the SBP or PRC during the follow-up period of 1 year. In a second experiment, the kidneys of young rats received an X-ray dose of 20 Gy. Subsequently, rats were kept on a standard diet (110 mmol sodium/kg) or a sodium-poor diet (10 mmol sodium/kg). On both diets, SBP started to rise rapidly 3 months after kidney irradiation. Sodium balance studies carried out at that time revealed an increased sodium retention in the irradiated rats compared to controls on the same diet. In rats on a low sodium intake, there was neither a delay nor an alleviation in the development of hypertension. Compared to controls, the PRC tended to be lower in irradiated rats up to 4 months after irradiation. Subsequently, malignant hypertension developed in all 20 Gy rats, resulting in pressure natriuresis, stimulating the renin-angiotensin system. Our findings indicated that hypertension after bilateral kidney irradiation was not primarily the result of an activation of the renin-angiotensin system. Although there were some indications that sodium retention played a role, dietary sodium restriction did not influence the development of hypertension.

    Full Text Available Background: Inguinal hernia repair remains one of the most common operations performed by pediatric surgeons. We described a new surgical approach for treating bilateral inguinal hernias in girls through a small single transverse supra-pubic incision. Materials and Methods: A new approach was performed on female children 12-years-old and younger with bilateral inguinal hernias between January 2005 and April 2012. Technique: A single transverse suprapubic incision (1-1.5 cm was made. Using sharp and blunt dissection bilateral hernias were exposed and repaired using a standard high ligation. Results: Ninety-nine girls with a preoperative clinical diagnosis of bilateral inguinal hernia were included. Median age was 2 years (range: 1 month to 12 years. All patients underwent general anesthesia. Median operative time was 12 minutes (range 5-22. There were no intra-operative complications or misdiagnosis. Two patients had bilateral sliding hernias and the remainder had indirect hernias. Post-operatively two patients developed non-expanding small hematomas, both treated non-operatively without sequelae. There were zero hernia recurrence and median follow-up was 5 years (range: 1-8 years on 99% of patients. Conclusion: We described a new, safe, simple, and rapid approach for bilateral inguinal hernia repair in female pediatric population. A single transverse suprapubic skin incision was adequate for exposing both inguinal regions with excellent postoperative results.

  17. Economic Diplomacy in Africa: The Impact of Regional Integration versus Bilateral Diplomacy on Bilateral Trade

    DEFF Research Database (Denmark)

    Afesorgbor, Sylvanus Kwaku

    The paper examines the impact of two main instruments of economic diplomacy — regional integration and commercial diplomacy on export flows among African states. We test whether there is any evidence of a trade-off or complementary interaction between these two instruments in trade facilitation. We...... compare the effects of these two instruments of economic diplomacy on bilateral trade by employing a gravity model for 45 African states over the period 1980-2005. The results show that bilateral diplomatic exchange is a relatively more significant determinant of bilateral exports among African states...... compared to regional integration. We also find a nuanced interaction between these two instruments of economic diplomacy: the trade–stimulating effect of diplomatic exchange is less pronounced among African countries that shared membership of the same regional bloc. Generally, this could mean...

    Full Text Available 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.

    2011-02-01

    This report satisfies the initial phase of Task WP-2.3.4 Alternative Sodium Recovery Technology, Subtask 1; Develop Near-Tank Nitrate/Nitrite Destruction Technology. Some of the more common anions in carbon steel waste tanks at SRS and Hanford Site are nitrate which is corrosive, and nitrite and hydroxide which are corrosion inhibitors. At present it is necessary to periodically add large quantities of 50 wt% caustic to waste tanks. There are three primary reasons for this addition. First, when the contents of salt tanks are dissolved, sodium hydroxide preferentially dissolves and is removed. During the dissolution process the concentration of free hydroxide in the tank liquid can decrease from 9 M to less than 0.2 M. As a result, roughly half way through the dissolution process large quantities of sodium hydroxide must be added to the tank to comply with requirements for corrosion control. Second, hydroxide is continuously consumed by reaction with carbon dioxide which occurs naturally in purge air used to prevent buildup of hydrogen gas inside the tanks. The hydrogen is generated by radiolysis of water. Third, increasing the concentration of hydroxide increases solubility of some aluminum compounds, which is desirable in processing waste. A process that converts nitrate and nitrite to hydroxide would reduce certain costs. (1) Less caustic would be purchased. (2) Some of the aluminum solid compounds in the waste tanks would become more soluble so less mass of solids would be sent to High Level Vitrification and therefore it would be not be necessary to make as much expensive high level vitrified product. (3) Less mass of sodium would be fed to Saltstone at SRS or Low Level Vitrification at Hanford Site so it would not be necessary to make as much low level product. (4) At SRS less nitrite and nitrate would be sent to Defense Waste Processing Facility (DWPF) so less formic acid would be consumed there and less hydrogen gas would be generated. This task involves

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

    This report describes the feasibility, calibration, and safety considerations of a non-destructive, in situ, quantitative, volumetric soil carbon analytical method based on inelastic neutron scattering (INS). The method can quantify values as low as 0.018 gC/cc, or about 1.2% carbon by weight with high precision under the instrument's configuration and operating conditions reported here. INS is safe and easy to use, residual soil activation declines to background values in under an hour, and no radiological requirements are needed for transporting the instrument. The labor required to obtain soil-carbon data is about 10-fold less than with other methods, and the instrument offers a nearly instantaneous rate of output of carbon-content values. Furthermore, it has the potential to quantify other elements, particularly nitrogen. New instrumentation was developed in response to a research solicitation from the U.S. Department of Energy (DOE LAB 00-09 Carbon Sequestration Research Program) supporting the Terrestrial Carbon Processes (TCP) program of the Office of Science, Biological and Environmental Research (BER). The solicitation called for developing and demonstrating novel techniques for quantitatively measuring changes in soil carbon. The report includes raw data and analyses of a set of proof-of-concept, double-blind studies to evaluate the INS approach in the first phase of developing the instrument. Managing soils so that they sequester massive amounts of carbon was suggested as a means to mitigate the atmospheric buildup of anthropogenic CO{sub 2}. Quantifying changes in the soils' carbon stocks will be essential to evaluating such schemes and documenting their performance. Current methods for quantifying carbon in soil by excavation and core sampling are invasive, slow, labor-intensive and locally destroy the system being observed. Newly emerging technologies, such as Laser Induced Breakdown Spectroscopy and Near-Infrared Spectroscopy, offer soil

    Hypersexuality is a rare but well recognized condition following brain injury. It has been described secondarily to dysfunction in the hypothalamus, the temporal and frontal lobes. We report a 63 year-old man that developed neuropsychological disturbances with hypersexuality as a prominent feature, disinhibition and moderate memory loss, hypersomnia and irritability after a bilateral paramedian thalamic infarction. A SPECT showed frontal hypoperfusion. We believe that these findings are expression of frontal-subcortical circuits dysfunction, particularly the orbitofrontal circuit, secondary to dorso medial thalamic infarction which probably plays a role in the determination of human sexual behavior. This case favors a thalamic modulation of frontal function.

  17. A bilateral advantage for storage in visual working memory.

    Umemoto, Akina; Drew, Trafton; Ester, Edward F; Awh, Edward

    2010-10-01

    Various studies have demonstrated enhanced visual processing when information is presented across both visual hemifields rather than in a single hemifield (the bilateral advantage). For example, Alvarez and Cavanagh (2005) reported that observers were able to track twice as many moving visual stimuli when the tracked items were presented bilaterally rather than unilaterally, suggesting that independent resources enable tracking in the two visual fields. Motivated by similarities in the apparent capacity and neural substrates that mediate tracking and visual working memory (WM), the present work examined whether or not a bilateral advantage also arises during storage in visual WM. Using a recall procedure to assess working memory for orientation information, we found a reliable bilateral advantage; recall error was smaller with bilateral sample displays than with unilateral displays. To demonstrate that the bilateral advantage influenced storage per se rather than just encoding efficiency, we replicated the observed bilateral advantage using sequentially presented stimuli. Finally, to further characterize how bilateral presentations enhanced storage in working memory, we measured both the number and the resolution of the stored items and found that bilateral presentations lead to an increased probability of storage, rather than enhanced mnemonic resolution. Thus, the bilateral advantage extends beyond the initial selection and encoding of visual information to influence online maintenance in visual working memory. Copyright 2010 Elsevier B.V.

    One means of countering a hazardous asteroid is discussed: destruction of the object using a nuclear charge. Explosion of such an asteroid shortly before its predicted collision would have catastrophic consequences, with numerous highly radioactive fragments falling onto the Earth. The possibility of exploding the asteroid several years before its impact is also considered. Such an approach is made feasible because the vast majority of hazardous objects pass by the Earth several times before colliding with it. Computations show that, in the 10 years following the explosion, only a negligible number of fragments fall onto the Earth, whose radioactivity has substantially reduced during this time. In most cases, none of these fragments collides with the Earth. Thus, this proposed method for eliminating a threat from space is reasonable in at least two cases: when it is not possible to undergo a soft removal of the object from the collisional path, and to destroy objects that are continually returning to near-Earth space and require multiple removals from hazardous orbits.

    Non-destructive analytical method is favored for the measurement of samples from the field of cultural properties. Among many scientific methods, X-ray fluorescence spectrometry and X-ray diffraction method are frequently applied in this field. X-ray fluorescence spectrometer is the main method for the measurement of chemical composition of cultural properties when sample is not taken out. It is the most important concept during the measurement, that samples should be kept in the safety condition without any difficulty or defect. Because a sample from the field of cultural properties could not be cut or could not be laid down in some cases, instruments should be improved to admit these samples and conditions. It is one of the solutions for this point to equip a large sample chamber in the instrument. Several new instruments with large sample chamber which was specially designed for the cultural properties were explained. Applications of these instruments were also explained for the real archaeological and historical samples. Even the measurements is not quantitative and qualitative analysis only, the results is evaluated to be valuable for the understanding of the samples. The micro focus X-ray fluorescence spectrometer was also applied in this field. The method gave not only the ordinary chemical composition but also the structure of the samples by mapping. (author)

    High Energy X-ray cargo screening is a mature technology that has proven its value in the detection of contraband material hidden within cargo including fully loaded sea containers. To date high energy screening has been largely applied to manifest verification and to drug detection. However, the dramatic change in world terrorism has altered the application. Now it is essential that weapons of mass destruction (WMD"s) be interdicted with incredibly high accuracy. The implication of a missed detection has gone from loss of revenue or the lowering of the street price of drugs to potentially stopping, at least for some significant time, most world commerce. Screening containers with high energy x-rays (~250+ mm of steel penetration) is capable of detecting all nuclear threats at a fraction of the strategically important mass. The screening operation can be automated so that no human decisions are required with very low false alarms. Finally, the goal of 100% inspection of cargo inbound to the United States from the twenty largest international ports is an achievable goal with hardware costs in the area of that already spent on airport security.

    ENDEF, an initiative of the European Commission, DG XVII (Energy) was well supported by the European industrial institutions working in assistance with nuclear industrial organisations in the CEEC`s (Central and Eastern European Countries) and NIS`s (New Independent States). This Forum provides effectively a platform for open discussion between representatives of industrial actors active in the NDE (Non Destructive Examination)/ISI (In Service Inspection) field with the purpose to establish a co-operation pattern between qualified representatives of the EU (European Union) industry to offer a better co-ordinated and well defined assistance to the CEEC`s and NIS in the field of NDE/ISI, and to lay the ground for further industrial co-operation. ENDEF developed a strategy to follow for the establishment of co-operation projects. This strategy is now used to understand the extent of past or present assistance projects and to identify the areas where more co-operation is needed. ENDEF encourages the creation in the NIS`s and CEEC`s of similar forums in order to increase the co-operation and co-ordination. ENDEF is also working in perfect agreement with the European Network ENIQ, piloted by the European plant operators. This identity of views lead to the leadership by the ENDEF co-ordinator of the ENIQ Task 3 involving Applications of the European Methodology for ISI qualification in the CEEC`s and NIS`s and presently fully integrated in ENDEF.

    A mobile system for non-destructive assay (NDA), developed at the Los Alamos National Laboratory, provides accurate and sensitive measurements for transuranic (TRU) isotopes contained in 208-iota drums of miscellaneous nuclear wastes. The NDA unit consists of four major subsystems: an assay chamber, counting and digital electronics, data acquisition, and a neutron generator. It performs both active and passive neutron waste measurements. The former determines the amount of fissile isotopes at a sensitivity level of 1 mg plutonium. The latter determines spontaneous fission and ..cap alpha..,n) isotopes at a comparable level. A complete assay consists of sequential active and passive measurements. The assay measurement and other supporting data are incorporated in a commercial spreadsheet program (Lotus 1,2,3) for further analysis, which includes various matrix corrections and a determination of whether or not the drum exceeds the 100-nCi/g threshold for TRU wastes. Field tests have been performed on three separate occasions, accomplishing more than 1800 waste drum assays. These waste drum assays are discussed, especially those comparing passive and active neutron measurements with independent segmented gamma scan assays. Results obtained with a set of 15 drums containing plutonium prepared from standards and actual hot waste matrices are also reviewed.

    KAERI The agent uses Cu ion and hydrazine in an inorganic acid solution. This agent is used for the dissolution of Fe and Ni ions in a spinel type nickel chromium ferrite. After decontamination, the generation of the secondary waste can be reduced by the destruction of hydrazine. Wellman et al. reported that hydrazine is decomposed to water and nitrogen by hydrogen peroxide in the presence of Cu{sup 2+} ion. N{sub 2}H{sub 4}+2H{sub 2}0{sub 2} (Cu{sup 2+} →) N{sub 2} +4H{sub 2}0 As the decrease of the hydrazine concentration, the solution pH also becomes to decrease. The decrease of solution pH can affect the integrity of structural metal. The objective of the study is to investigate the decomposition characteristics of hydrazine by hydrogen peroxide. The corrosion compatibility of metal after the decomposition of hydrazine is also investigated. The application of a decontamination solution to the primary coolant system before decommissioning is necessary to minimize the personnel dose rates. In foreign countries, system decontaminations have been performed several times by applying the dilute organic chemical decontamination process. To prepare against the decommissioning of the nuclear power plant, it is necessary to develop the unique domestic chemical decontamination process.

    Kinematic and neuromuscular synergies have been found in numerous aspects of human motion. This study aims to determine how effectively kinematic synergies in bilateral upper arm movements can be used to replicate complex activities of daily living (ADL) tasks using a sparse optimization algorithm. Ten right-handed subjects executed 18 rapid and 11 natural-paced ADL tasks requiring bimanual coordination while sitting at a table. A position tracking system was used to track the subjects’ arms in space, and angular velocities over time for shoulder abduction, shoulder flexion, shoulder internal rotation, and elbow flexion for each arm were computed. Principal component analysis (PCA) was used to generate kinematic synergies from the rapid-paced task set for each subject. The first three synergies accounted for 80.3 ± 3.8% of variance, while the first eight accounted for 94.8 ± 0.85%. The first and second synergies appeared to encode symmetric reaching motions which were highly correlated across subjects. The first three synergies were correlated between left and right arms within subjects, whereas synergies four through eight were not, indicating asymmetries between left and right arms in only the higher order synergies. The synergies were then used to reconstruct each natural-paced task using the l1-norm minimization algorithm. Temporal dilations of the synergies were introduced in order to model the temporal scaling of movement patterns achieved by the cerebellum and basal ganglia as reported previously in the literature. Reconstruction error was reduced by introducing synergy dilations, and cumulative recruitment of several synergies was significantly reduced in the first 10% of training task time by introducing temporal dilations. The outcomes of this work could open new scenarios for the applications of postural synergies to the control of robotic systems, with potential applications in rehabilitation. These synergies not only help in providing near

    Vocal cord paralysis is a rare cause of obstructive sleep apnea syndrome (OSAS). Recurrent laryngeal nerve injury after thyroid gland surgery is one of the leading causes of acquired vocal cord paralysis. A 46-year-old woman with OSAS due to bilateral abductor vocal cord paralysis was presented. She had thyroidectomy 30 years ago and had a weak, breathy voice. She had been referred with a history of high-pitched snoring, apnea witnessed by her spouse, and excessive daytime sleepiness for the last 5 years. Full-night polysomnography revealed that her apnea-hypopnea index was 72/h and minimal oxygen saturation level was 81%. There was no REM and deep sleep periods. Ear-nose-throat consultation offered an endoscopic bilateral posterior cordotomy operation via microscopic suspension laryngoscopy (MLS) as a treatment option. Instead of using a nasal positive airway pressure (nCPAP) device, she was treated surgically. Her OSAS resolved completely within 5 months of the surgery. Her phonation was preserved, and symptoms such as snoring and hypersomnolance disappeared. In OSAS patients with bilateral vocal cord paralysis, MLS-associated bilateral posterior cordotomy can be a choice of treatment as an alternative to nCPAP application.

    Schwab, K O; Krause, M

    1992-11-01

    In order to determine plasma and urine epinephrine levels after bilateral adrenalectomy, we examined a 16 year old young man with bilateral pheochromocytoma. Bilateral removal of the adrenals was performed because of a left sided pheochromocytoma relapse. An extra-adrenal pheochromocytoma could be excluded by scintigraphy. Macroscopically all adrenal tissue was removed during surgery. A modified radioenzymatic determination of the free catecholamines epinephrine, norepinephrine and dopamine was used according to Peuler and Johnson. Sulfoconjugated catecholamines were measured after addition of 60 microU arylsulfatase type VI. Urine catecholamine levels were determined fluorometrically. The elevated plasma andurine norepinephrine levels before surgery returned to normal after surgery. In contrast, plasma epinephrine levels returned to subnormal values thereafter but increases 5-fold at the end of anesthesia suggesting an extra-adrenal source of epinephrine. Urine epinephrine levels remained in the lower normal range. An insulin induced hypoglycemia was performed resulting in adrenergic symptoms of hypoglycemia and a subnormal increase of epinephrine. We conclude, that epinephrine mediated physiological regulations occur inspite of bilateral adrenalectomy probably by a regulated extra-adrenal source of epinephrine. The kidney could be the site of extra-adrenal epinephrine production.

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

    Full Text Available Corneal edema, hyphema, lens dislocation, iris atrophy, cataract and glaucoma cases due to bee sting are frequently reported. Optic neuropathy developing after a bee sting is rarely reported. A 46-year-old man applied to our clinic with visual loss. He had a history of transient loss of consciousness and bilateral severe visual loss after a bee sting 10 days ago. His first diagnosis was myocardial infarction and coronary angiography was applied in a private hospital; the angiography was found normal. In our clinic, his best-corrected visual acuity was 0.5 in the right eye and 0.7 in the left eye. The diagnosis was bilateral optic neuritis, and 64 mg/day oral methylprednisolone treatment was applied. Visual acuity improved to 1.0 in both eyes 39 days later. Optic neuritis due to bee sting is a rare case that can cause severe visual loss and responds well to systemic corticosteroid treatment. (Turk J Ophthalmol 2014; 44: 72-4

  6. Unusual Bilateral Rim Fracture in Femoroacetabular Impingement

    2015-01-01

    Full Text Available 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.

    antecedentes: el cáncer de mama en el hombre es una enfermedad con baja incidencia, que se reduce aún más cuando es bilateral sincrónica. Existen pocas publicaciones en los últimos años. Objetivo: establecer pautas para el tratamiento de este cáncer, aunque sea infrecuente. Caso clínico: paciente masculino de 75 años de edad, con tumores en ambas mamas, que se le resecaron completamente con exéresis de ganglios palpables. El estudio histopatológico informó que se trataba de un carcinoma ductal infiltrante no especificado. Se indicó tratamiento adyuvante con tamoxifeno y radioterapia; en la actualidad está libre de enfermedad. Conclusiones: el carcinoma mamario bilateral sincrónico en el varón es una enfermedad poco frecuente. Su tratamiento principal es la cirugía, de ahí la importancia del diagnóstico temprano. En la mayoría de los casos se requiere quimioterapia y radioterapia adyuvante porque suelen diagnosticarse en un estadio avanzado.

    Meniere disease (MD) is a heterogeneous clinical condition characterized by sensorineural hearing loss, episodic vestibular symptoms, and tinnitus associated with several comorbidities, such as migraine or autoimmune disorders (AD). The frequency of bilateral involvement may range from 5 to 50%, and it depends on the duration of the disease. We have performed a two-step cluster analysis in 398 patients with bilateral MD (BMD) to identify the best predictors to define clinical subgroups with a potential different etiology to improve the phenotyping of BMD and to develop new treatments. We have defined five clinical variants in BMD. Group 1 is the most frequently found, includes 46% of patients, and is defined by metachronic hearing loss without migraine and without AD. Group 2 is found in 17% of patients, and it is defined by synchronic hearing loss without migraine or AD. Group 3, with 13% of patients, is characterized by familial MD, while group 4, that includes 12% of patients, is associated by the presence of migraine in all cases. Group 5 is found in 11% of patients and is defined by AD. This approach can be helpful in selecting patients for genetic and clinical research. However, further studies will be required to improve the phenotyping in these clinical variants for a better understanding of the diverse etiological factors contributing to BMD. PMID:27822199

    Full Text Available Study Objective: To assess outcome from anaesthesia during laparoscopic bilateral simultaneous nephrectomy. Design: Retrospective study. Measurements: Preoperative Hb%, serum potassium, coagulation profile electrocardiography (ECG changes, 2D Echography, x-ray chest, haemodynamic changes, end-tidal carbon dioxide (EtCO 2 , fluid management and postoperative analgesia. Results: The mean age was 24.75 ± 14.35 years. The mean duration of surgery was 120 ± 80 minutes. The Hb%, serum creatinine and serum potassium were 9.4 ± 1.04%, 6.79 ± 4.91 meq/L and 3.61 ± 0.51 meq/L, respectively. Pulse rate mean blood pressure and EtCO 2 were recorded after creation of pneumoperitoneum and at 15, 30, 45 and after exsufflation of pneumoperitoneum. After pneumoperitoneum, there was increase in pulse rate, systolic blood pressure, diastolic blood pressure and EtCO 2 . After 30 minutes and throughout the surgery, these variables remained stable. Four patients required nitroglycerine infusion for intraoperative hypertention. Only one patient required packed cell volume (PCV transfusion and total intravenous fluid was 1 ± 0.5 L. At the time of exsufflation, there was decrease in pulse rate, systolic and diastolic blood pressure and EtCO 2 . Conclusion: Because of advancement in anaesthetic agents and muscle relaxant, there is safe outcome from anaesthesia during laparoscopic bilateral simultaneous nephrectomy.

  10. Bilateral high division of sciatic nerve

    2014-08-01

    Full Text Available Sciatic nerve is the thickest nerve in the body formed by the sacral plexus from L4 to S3 in the lesser pelvis. It emerges through the greater sciatic foramen below the piriformis and enter the gluteal region. Then the nerve passes on the back of the thigh and at the level of superior angle of popliteal fossa it terminates by dividing into tibial and common peroneal nerve. The knowledge of anatomical variations in the division of nerve is important for various surgical and anaesthetic procedures. During routine dissection in the department of anatomy, Mysore Medical College and Research Institute, Mysore, a rare bilateral high division of sciatic nerve was observed in a female cadaver aged about 40 years. In the present case there was bilateral high division of sciatic nerve. The nerve was seen dividing into two branches before it emerges through the greater sciatic foramen. The tibial nerve was entering the gluteal region below the piriformis muscle and common peroneal nerve was entering by piercing the piriformis. The knowledge of this variation is important as the nerve may get compressed with surrounding anatomical structures resulting in non discogenic sciatica. The awareness of variations is important for surgeons during various procedures like fracture, posterior dislocation of hip joint and hip joint replacement. The anatomical variations are important during deep intramuscular injections in gluteal region and also for anaesthetists during sciatic nerve block. [Int J Res Med Sci 2014; 2(4.000: 1785-1787

    2017-08-07

    A relatively young healthy man (barring obesity and distant gouty arthritis) was admitted with severe acute kidney injury (serum creatinine, 15.9 mg/dL) following acute gastroenteritis and occasional use of diclofenac. Abdominal ultrasound revealed mild left hydronephrosis due to staghorn stone and normal right kidney. Soon after, complete anuria necessitating haemodialysis developed without pain or evidence of infection. CT imaging revealed stones obstructing the right ureter. Following urological surgery, postobstructive diuresis developed and the serum creatinine came down to near normal. The stones were identified as uric acid stones.Anuria has a relatively narrow differential and painless (partially non-dilated) bilateral ureteral obstruction is a distinctly unusual cause. A review of the literature to cover all reported causes of bilateral ureteral obstruction is presented. Only a minority of cases were not associated with an underlying malignant disease or its treatment. The multifactorial aetiology of the patient's acute kidney injury (volume depletion, diclofenac and obstructive uropathy) is presented and discussed. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

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

    Full Text Available Parotid gland tuberculosis is an extremely rare form of extrapulmonary tuberculosis, even in countries where tuberculosis is endemic like India; however, it should be included as one of the differentials of discrete parotid swelling as it generally presents as a slow-growing mass indistinguishable from a malignancy and even imaging too, can’t differentiate these clearly. The majority of the previously reported cases were mostly unilateral and diagnosed by histopathological examination of post parotidectomy specimens. Here we are describing a case of tuberculosis of both parotid glands in a 25 year-old male who was referred to us with bilateral parotid region swelling of two month duration. Tubercular parotiditis was confirmed by demonstration of epithelioid granuloma and caseous necrosis compatible with TB on fine needle aspiration cytology (FNAC. He was treated with four drug anti-TB regimen (2HERZ + 4HR leading to full recovery and complete disappearance of swelling and symptoms with no recurrence till one year of follow up. Apart from rarity due to bilateral involvement, this case report highlights the clinical presentation, ultrasonography and other imaging findings, and significance of FNAC in diagnosis of this uncommon entity reinforcing the fact that the diagnosis of parotid gland tuberculosis requires a high degree of clinical suspicion.

    Full Text Available To present a rare complication, such as bilateral cataracts, in a man who sustained a high-voltage electrical injury. A 35- year-old man was admitted with a complaint of decrease in visual acuity. He had a history of a contact with a power line carrying 30.000 volts of electricity while working at a construction site. Examination at a burn center revealed second-degree facial, neck and left foot burns. One month later, the patient underwent amputation of fourth and fifth toes of his left foot. During the next 6 months, he noted decreasing vision in both eyes. Ocular examination 1 year after the accident revealed that the patient’s visual acuity had deteriorated to 1/10 in both eyes. The cornea on the left eye showed superficial punctate opacities. The lenses in both eyes had anterior subcapsular cortical lens opacities and posterior subcapsular opacities. Uncomplicated bilateral phacoemulsification surgery with intraocular lens implantation was performed and the patient’s visual acuity returned to 10/10 in both eyes. We noted that the fundus remained normal in both eyes. Electrical cataracts are still a serious potential complication that may occur after electrical injury. Awareness of this by burn team members is important for providing optimal treatment to those who have suffered an electrical injury. (Turk J Ophthalmol 2011; 41: 197-9

    2014-11-01

    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.

Although his general condition improved after intravenous acyclovir administration, the patient presented with visual loss in both eyes 4 days after admission. Visual acuity in his right eye was 20/200 and his left eye had light perception alone. Both eyes showed panretinal arteritis diagnosed as acute retinal necrosis. Panretinal photocoagulation was performed for both eyes. Progression of retinal detachment was prevented in both eyes; however, visual acuity of the left eye was totally lost because of neovascular glaucoma. Visual acuity of the right eye recovered to 20/20.Conclusion: Although cases of bilateral acute retinal necrosis have been reported after herpetic encephalitis, this condition is rare after herpetic meningitis. Prophylactic acyclovir therapy and early panretinal photocoagulation may prevent retinal detachment and improve the prognosis. Neurologists and ophthalmologists should be aware that not only herpetic encephalitis but also herpetic meningitis can lead to acute retinal necrosis within a very short interval.Keywords: acute retinal necrosis, herpetic meningitis, herpes simplex, varicella zoster virus

  18. Destruction and Sequestration of H2O on Mars

    Science.gov (United States)

    Clark, Benton

    2016-07-01

    The availability of water in biologically useable form on any planet is a quintessential resource, even if the planet is in a zone habitable with temperature regimes required for growth of organisms (above -18 °C). Mars and most other planetary objects in the solar system do not have sufficient liquid water at their surfaces that photosynthesis or chemolithoautotrophic metabolism could occur. Given clear evidence of hydrous mineral alteration and geomorphological constructs requiring abundant supplies of liquid water in the past, the question arises whether this H2O only became trapped physically as ice, or whether there could be other, more or less accessible reservoirs that it has evolved into. Salts containing S or Cl appear to be ubiquitous on Mars, having been measured in soils by all six Mars landed missions, and detected in additional areas by orbital investigations. Volcanoes emit gaseous H2S, S, SO2, HCl and Cl2. A variety of evidence indicates the geochemical fate of these gases is to be transformed into sulfates, chlorides, chlorates and perchlorates. Depending on the gas, the net reaction causes the destruction of between one and up to eight molecules of H2O per atom of S or Cl (although hydrogen atoms are also released, they are lost relatively rapidly to atmospheric escape). Furthermore, the salt minerals formed often incorporate H2O into their crystalline structures, and can result in the sequestration of up to yet another six (sometimes, more) molecules of H2O. In addition, if the salts are microcrystalline or amorphous, they are potent adsorbents for H2O. In certain cases, they are even deliquescent under martian conditions. Finally, the high solubility of the vast majority of these salts (with notable exception of CaSO4) can result in dense brines with low water activity, aH, as well as cations which can be inimical to microbial metabolism, effectively "poisoning the well." The original geologic materials on Mars, igneous rocks, also provide some

    In the absence of firm recommendations, we analyzed whether unilateral thoracic puncture is sufficient for bilateral pleural effusion (PE), or if the procedure needs to be performed in both sides. Prospective study of patients seen consecutively for bilateral PE during a period of 3 years and 9 months. All patients underwent simultaneous bilateral thoracocentesis. The standard protocol variables collected in our hospital served as study parameters. Size of PE, presence of chest pain or fever, or accompanying lung abnormalities, different attenuation values on chest computed tomography, presence of loculated pleural fluid, and radiological resolution in a single side were also evaluated. A total of 36 patients (19 men; mean age 68.5 ± 16.5 years) were included. The etiology of the effusion was different in each side in only 2 patients (5.6%). In 6/32 cases (18.8%), the biological analysis of the pleural fluid (in terms of transudate/exudate) from both sides did not correspond with the etiological diagnosis of the effusion. Correlation between biochemical parameters analyzed in the fluid from both sides (Pearson's correlation coefficient) ranged between 0.74 (LDH) and 0.998 (NT-proBNP). As different diagnoses in each side were found in only 2 patients, the circumstances in which bilateral diagnostic thoracocentesis would be necessary could not be determined. Simultaneous bilateral thoracocentesis does not appear to be recommendable. Larger series are needed to establish which factors might suggest the need for simultaneous puncture of both PE.

    Mental imagery is a powerful mechanism that may facilitate visual perception as well as compensate for it. The role of V1 in mental imagery is still a matter of debate. Our goal here was to investigate whether visual imagery was still possible in case of bilateral V1 destruction behaviorally evidenced by total clinical blindness and if so, whether it might boost residual visual perception. In a factorial fMRI design, faces, scenes or scrambled images were presented while a rare patient with cortical blindness over the whole visual field due to bilateral V1-lesions (TN) was instructed to imagine either an angry person or a neutral object (tree). The results show that visual imagery of a person activates frontal, parietal and occipital brain regions similar to control subjects and hence suggest that V1 is not necessary for visual imagery. In addition, the combination of visual stimulation and visual imagery of socio-emotional stimuli triggers activation in superior parietal lobule (SPL) and ventromedial (vmPFC) and dorsolateral prefrontal cortex (DLPFC). Finally, activation during residual vision, visual imagery and their interaction overlapped in the SPL, arguing for a central role of feeling in V1-independent vision and imagery.

  1. The bilateral advantage for famous faces: interhemispheric communication or competition?

    Baird, Lyndsay M; Burton, A Mike

    2008-04-01

    The bilateral advantage for the perception of famous faces was investigated using a redundant target procedure. In experiment 1 we compared simultaneous presentation of stimuli (a) bilaterally and (b) one above the other in the central field. Results showed a redundancy advantage, but only when faces were presented bilaterally. This result lends support to the notion of interhemispheric communication using cross-hemisphere representations. Experiment 2 examined the nature of such communication by comparing bilateral presentation of identical face images, with bilateral presentation of different images of the same person. When asked to make a familiar/unfamiliar face judgement, participants showed evidence for a redundancy advantage under both bilateral conditions. This suggests that the nature of the information shared in interhemispheric communication is abstract, rather than being tied to superficial stimulus properties.

    Full text: The natural volcanic glass obsidian is one of the classical objects of archaeometric analyses. Reliable provenancing by means of the highly specific chemical composition, the 'chemical fingerprint', can provide information about trading routes, extension of territory, long-distance contacts and the mobility of prehistoric people. Since the pioneer work of Cann and Renfrew in 1964 [1] various analytical methods have been employed on obsidian samples in order to locate their provenance. The existing data already offers important knowledge about long-distance interactions between prehistoric human populations. However, most applied techniques just show a small part of the element spectrum. Latest studies showed that published results gained by different analytical methods are not consistent due to systematic errors [2-3]. Therefore, the application of three complementary analytical techniques on the same set of raw material samples allows both a better characterization of obsidian sources and a comparison and validation of analytical results. The aim of this multi-methodical approach is to apply in particular: 1) lon Beam Analysis (IBA) comprising of Particle Induced X-ray Emission (PIXE) and Particle Induced Gamma-ray Emission (PIGE), 2) Instrumental Neutron Activation Analysis (INAA), 3) Laser Ablation-lnductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS), to detect a maximum element spectrum and to compare element concentrations determined with at least two analytical techniques. This approach should check the accuracy and reliability of analytical results and should show a maximum of compositional differences between European obsidian sources to reveal the most characteristic 'chemical fingerprint' composed of more than 40 elements. These investigations are part of a new multi-methodical analytical database called the 'Obsidian Least Destructive Analysis Provenancing System' (OLDAPS). This novel scientific approach for

    This slide presentation reviews the work in non-destructive evaluation (NDE) of cryogenic storage tanks. Four large cryogenic tanks, constructed in 1965 with perlite insulation in the annular regions, are of concern. The construction of the tanks, two Liquid Oxygen (LOX) and two Liquid Hydrogen (LH2), are described. The loss rate for the LOX tank at Pad A is slightly higher than that for the one at Pad B. The concerns for the LH2 tank at Pad B are that there is a significantly higher boil-off rate than that at Pad A, that there is mold growth, indicative of increased heat flow, that there is a long down-time needed for repairs, and that 3 of 5 full thermal cycles have been used on the Pad B LH2 tank. The advantages and disadvantages of thermal imaging are given. A detailed description of what is visible of the structures in the infra-red is given and views of the thermal images are included. Missing Perlite is given as the probable cause of the cold spot on the Pad B LH2 tank. There is no indications of problematic cold regions on the Pad A LH2 tank, as shown by the thermal images given in the presentation. There is definite indication of a cold region on the Pad A LOX tank. There is however concerns with thermal imaging, as thermal images can be significantly effected by environmental conditions, image differences on similar days but with different wind speeds. Other effects that must be considered include ambient temperature, humidity levels/dew, and cloud reflections

  4. PROCESSING ALTERNATIVES FOR DESTRUCTION OF TETRAPHENYLBORATE

    2007-02-27

    Two processes were chosen in the 1980's at the Savannah River Site (SRS) to decontaminate the soluble High Level Waste (HLW). The In Tank Precipitation (ITP) process (1,2) was developed at SRS for the removal of radioactive cesium and actinides from the soluble HLW. Sodium tetraphenylborate was added to the waste to precipitate cesium and monosodium titanate (MST) was added to adsorb actinides, primarily uranium and plutonium. Two products of this process were a low activity waste stream and a concentrated organic stream containing cesium tetraphenylborate and actinides adsorbed on monosodium titanate (MST). A copper catalyzed acid hydrolysis process was built to process (3, 4) the Tank 48H cesium tetraphenylborate waste in the SRS's Defense Waste Processing Facility (DWPF). Operation of the DWPF would have resulted in the production of benzene for incineration in SRS's Consolidated Incineration Facility. This process was abandoned together with the ITP process in 1998 due to high benzene in ITP caused by decomposition of excess sodium tetraphenylborate. Processing in ITP resulted in the production of approximately 1.0 million liters of HLW. SRS has chosen a solvent extraction process combined with adsorption of the actinides to decontaminate the soluble HLW stream (5). However, the waste in Tank 48H is incompatible with existing waste processing facilities. As a result, a processing facility is needed to disposition the HLW in Tank 48H. This paper will describe the process for searching for processing options by SRS task teams for the disposition of the waste in Tank 48H. In addition, attempts to develop a caustic hydrolysis process for in tank destruction of tetraphenylborate will be presented. Lastly, the development of both a caustic and acidic copper catalyzed peroxide oxidation process will be discussed.

    Spermatocytic seminoma (SS) is a rare testicular neoplasm characterized by a palpable, painless, slowly enlarging mass in the testis. Even more rare is a synchronous bilateral presentation. Only eight cases of bilateral SS have been reported in the literature, of which three cases were present with synchronous testis enlargement, and five were sequential. Here, we report an additional case of synchronous bilateral SS and present a comprehensive relevant literature review concerning clinical features, histopathology, and treatment. PMID:23915031

    Conclusion: The early functional recovery of bilateral TKA patient lags behind that of unilateral TKA patient for the first 5 days, becomes equal by the 14 th day and remains equal till 1 year after surgery. Bilateral TKA patients regain their preoperative functional status by 6 weeks against 3 months for unilateral TKA. The operative status of the contralateral knee makes no difference to early functional recovery after unilateral TKA. With bilateral TKA, there is no difference in pain and ROM parameters.

    We present a case of bilateral adrenal haemorrhage (BAH) associated with heparin-induced thrombocytopaenia (HIT) in a 61-year-old man admitted to hospital for the treatment of Fournier's gangrene. He presented to hospital with scrotal swelling and fever, and developed spreading erythaema and a gangrenous scrotum. His scrotum was surgically debrided and intravenous broad-spectrum antibiotics were administered. Unfractionated heparin was given postoperatively for venous thromboembolism prophylaxis. The patient deteriorated clinically 8-11 days postoperatively with delirium, chest pain and severe hypertension followed by hypotension and thrombocytopaenia. Abdominal CT scan revealed bilateral adrenal haemorrhage. Antibodies to the heparin-platelet factor 4 complex were present. HIT-associated BAH was diagnosed and heparin was discontinued. Intravenous bivalirudin and hydrocortisone were started, with rapid improvement in clinical status. BAH is a rare complication of HIT and should be considered in the postoperative patient with unexplained clinical deterioration.

    2011-02-01

    This report satisfies the initial phase of Task WP-2.3.4 Alternative Sodium Recovery Technology, Subtask 1; Develop Near-Tank Nitrate/Nitrite Destruction Technology. Some of the more common anions in carbon steel waste tanks at SRS and Hanford Site are nitrate which is corrosive, and nitrite and hydroxide which are corrosion inhibitors. At present it is necessary to periodically add large quantities of 50 wt% caustic to waste tanks. There are three primary reasons for this addition. First, when the contents of salt tanks are dissolved, sodium hydroxide preferentially dissolves and is removed. During the dissolution process the concentration of free hydroxide in the tank liquid can decrease from 9 M to less than 0.2 M. As a result, roughly half way through the dissolution process large quantities of sodium hydroxide must be added to the tank to comply with requirements for corrosion control. Second, hydroxide is continuously consumed by reaction with carbon dioxide which occurs naturally in purge air used to prevent buildup of hydrogen gas inside the tanks. The hydrogen is generated by radiolysis of water. Third, increasing the concentration of hydroxide increases solubility of some aluminum compounds, which is desirable in processing waste. A process that converts nitrate and nitrite to hydroxide would reduce certain costs. (1) Less caustic would be purchased. (2) Some of the aluminum solid compounds in the waste tanks would become more soluble so less mass of solids would be sent to High Level Vitrification and therefore it would be not be necessary to make as much expensive high level vitrified product. (3) Less mass of sodium would be fed to Saltstone at SRS or Low Level Vitrification at Hanford Site so it would not be necessary to make as much low level product. (4) At SRS less nitrite and nitrate would be sent to Defense Waste Processing Facility (DWPF) so less formic acid would be consumed there and less hydrogen gas would be generated. This task involves

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

The symmetry between the right and left eye of 397 subjects in 14 biometric parameters, spherical equivalent of refractive error (SE), Jackson crossed cylinder power of refractive error astigmatism with axes at 90° and 180° (RJ0) and at 45° and 135° (RJ45), best-corrected visual acuity (BCVA), average corneal curvature (CC), Jackson crossed cylinder power of corneal astigmatism (CJ0 and CJ45), corneal asphericity coefficient (Q), intraocular pressure (IOP), central corneal thickness (CCT), axial length (AL), anterior chamber depth (ACD), lens thickness (LT) and vitreous chamber depth (VCD), was assessed by comparative data analysis. Aside from RJ0 (p = 0.00), RJ45 (p = 0.02) and Q (p = 0.00), the overall interocular differences of other biometric parameters between fellow eyes were not significant (p > 0.05). The interocular correlation and Bland-Altman plots showed a good agreement between fellow eyes in 14 biometric parameters. Correlations between interocular differences in SE and that in RJ0 (p = 0.03), CC (p = 0.00), AL (p = 0.00) and VCD (p = 0.00) were statistically significant. There were similar strong linear relationships between refractive error astigmatism vectors and corneal astigmatism vectors in bilateral eyes. There were negative correlations of RJ45 and CJ45 between bilateral eyes. A potentially clinically important interocular symmetry in SE, BCVA, CC, CJ0, CJ45, IOP, CCT, AL, ACD, LT and VCD is found in this research, while the differences of RJ0, RJ45 and Q between left and right eyes seem a bit large. The negative interocular relationships of RJ45 and CJ45 demonstrate moderate mirror symmetry exists among fellow eyes. High interocular symmetry in bilateral eyes may be helpful in intraocular lens power calculation, intraocular pressure evaluation, post-operative visual acuity and refraction

    The wastewater discharged from tanneries lack biodegradability due to the presence of recalcitrant compounds at significant concentration. The focal theme of the present investigation was to use chemo-autotrophic activated carbon oxidation(CAACO) reactor, an immobilized cell reactor using chemoautotrophs for the treatment of tannery wastewater. The treatment scheme comprised of anaerobic treatment, sand filtration, and CAACO reactor, which remove COD, BOD, TOC, VFA and sulphides respectively by 86%, 95%, 81%,71% and 100%. Rice bran mesoporous activated carbon prepared indigenously and was used for immobilization of chemoautotrophs. The degradation of xenobiotic compounds by CAACO was confirmed through HPLC and FT-IR techniques.

    Full Text Available There are limited data about the cutaneous metastases of gynecological malignancies in the literature. Based on this limited number of studies, cutaneous metastases from gynecological malignancies are uncommon occurrences. Cutaneous metastases from the synchronous endometrioid carcinoma of the uterine corpus and bilateral ovaries arising from endometriosis are extremely rare. Herein, we report a 51-year-old woman with FIGO Stage 1A Grade 1 endometrial endometrioid-type adenocarcinoma and synchronous bilateral Stage 1B ovarian endometrioid-type adenocarcinoma who presented 34 months following total abdominal hysterectomy and bilateral salpingo-oophorectomy with skin metastases. After the patient underwent an excisional biopsy, we applied a palliative radiotherapy. The patient received the combination therapy with cisplatin and doxorubicin after the completion of radiotherapy but the disease evolution was rapidly fatal and the patient died 4 months after her admission to our department due to widely disseminated disease.

    The outcome of acoustic neuroma (vestibular schwannoma) surgery continues to improve rapidly. Advances can be attributed to several fields, but the most important contributions have arisen from the identification of the genes responsible for the dominant inheritance of neurofibromatosis types 1 (NF1) and 2 (NF2) and the development of magnetic resonance imaging with gadolinium enhancement for the early anatomic confirmation of the pathognomonic, bilateral vestibular schwannomas in NF2. These advances enable early diagnosis and treatment when the tumors are small in virtually all subjects at risk for NF2. The authors suggest that advising young NF2 patients to wait until complications develop, especially hearing loss, before diagnosing and operating for bilateral eighth nerve schwannomas may not always be in the best interest of the patient. To the authors' knowledge, this is the first reported case of preservation of both auditory and vestibular function in a patient after bilateral vestibular schwannoma excision.

    Full Text Available Marfan syndrome is an autosomal dominant systemic disorder of the connective tissue. Marfan syndrome affects most organs and tissues, especially the skeleton, lungs, eyes, heart, and the large blood vessels. Eye involvement may be in the form of retinal detachment which is a potentially dangerous manifestation for its sight threatening nature .We report a case where a 17 year old male developed sudden blindness due to spontaneous bilateral retinal detachment. Examination revealed features of Marfan syndrome and was stamped as a case of Marfan syndrome by Ghent criteria . The point to stress upon is that a young male developing spontaneous retinal detachment, a diagnosis of underlying Marfan syndrome should be kept in mind if appropriate clinical stigmata are present.

    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.

  7. Bilaterally Weighted Patches for Disparity Map Computation

    2015-03-01

    Full Text Available Visual correspondence is the key for 3D reconstruction in binocular stereovision. Local methods perform block-matching to compute the disparity, or apparent motion, of pixels between images. The simplest approach computes the distance of patches, usually square windows, and assumes that all pixels in the patch have the same disparity. A prominent artifact of the method is the "foreground fattening effet" near depth discontinuities. In order to find a more appropriate support, Yoon and Kweon introduced the use of weights based on color similarity and spatial distance, analogous to those used in the bilateral filter. This paper presents the theory of this method and the implementation we have developed. Moreover, some variants are discussed and improvements are used in the final implementation. Several examples and tests are presented and the parameters and performance of the method are analyzed.

    2016-10-08

    In this paper, we describe the case of a 62-year-old female with recurring episodes of sudden deafness with vertigo and facial paresis. Within a month's time, this resulted in bilateral deafness and vestibular areflexia. Erroneously, the patient was diagnosed with sudden deafness of unknown origin and subsequently with neuroborreliosis (Lyme disease). The true diagnosis of relapsing polychondritis (RP) was revealed 9 months after initial presentation. The diagnostic delay is in part explained by the fact that, by definition, the disease has to relapse before the diagnosis can be made, but also by its pluriform clinical presentation. Timely identification of RP as the cause of this profound sensorineural hearing loss proved to be important. It was key in instigating adequate follow-up, and allowed for cochlear implantation before total cochlear obliteration, which might have hampered optimal hearing rehabilitation.

    Full Text Available X-linked juvenile retinoschisis is a rare hereditary retinal disease characterized by a tangential splitting of the neurosensory retina which may cause early-onset visual impairment. Existence of the retinal neurosensory layer splitting on cross-sectional images of optical coherance tomography (OCT and the absence of leakage on fluorescein angiography (FA help confirming the diagnosis. Such diagnostic tests are also helpful in determining the management of the disease. However, most of the retinoschisis cavities remain stable and rarely extend to the posterior pole, many authors suggest laser prophylaxis to avoid the potential risk of retinal detachment due to holes in the outer retinal layer. Herein, we report a case with bilateral foveal retinoschisis accompanying unilateral peripheral retinoschisis who was evaluated with detailed ophthalmologic examination. Visual acuity, fundoscopy, OCT, and FA remained stable in the second year of follow-up after prophylactic argon laser treatment.

    Idiopathic granulomatous mastitis (IGM) is an uncommon benign disorder of the breast. At clinical examination, IGM is characterized by an inflammatory process of the breast, usually unilateral. Possible clinical findings are palpable mass with erythematous skin, pain, sterile abscesses, fistula and nipple retraction. Mammography and ultrasound findings are not specific for IGM. Magnetic resonance imaging (MRI) is a useful tool for the differential diagnosis; it is also necessary to delineate the exact extension of the disease and to plan the correct treatment. Final diagnosis is histological. We described an unusual case of IGM with bilateral involvement in a patient with history of pacemaker implantation and IGM typical clinical symptoms. Mammography, ultrasound, and MRI examinations were performed to identify the inflammatory disorder and to plan the correct therapy. Imaging features were correlated with final histological diagnosis of IGM.

    2010-05-01

    A paradigmatic example of an emotional bias in decision making is the framing effect, where the manner in which a choice is posed--as a potential loss or a potential gain--systematically biases an ensuing decision. Two fMRI studies have shown that the activation in the amygdala is modulated by the framing effect. Here, contrary to an expectation based on these studies, we show that two patients with Urbach-Wiethe (UW) disease, a rare condition associated with congenital, complete bilateral amygdala degeneration, exhibit an intact framing effect. However, choice preference in these patients did show a qualitatively distinct pattern compared to controls evident in an increased propensity to gamble, indicating that loss of amygdala function does exert an overall influence on risk-taking. These findings suggest either that amygdala does contribute to decision making but does not play a causal role in framing, or that UW is not a pure lesion model of amygdala function.

    Full Text Available Tuberculosis is an important cause of uveitis in our country. India has been declared the country with the highest tuberculosis burden with 25 % of the cases . (1 This is especially true in Andhra Pradesh and Telangana which have a high percentage of affected patients. However , tuberculous uveitis is usually a unilateral presen tation. We report a case of bilateral uveitis of tuberculous origin in a 55 year old woman. She presented with different tuberculous manifestations in the two eyes. While the RE showed non granulomatous uveitis with sclerosing keratitis , the LE showed gran ulomatous uveitis with mutton fat keratic precipitates. Systemic examination revealed an enlarged lymph node which was positive for tuberculosis on biopsy. She was hence diagnosed as extra pulmonary tuberculosis and was treated with ATT regimen. In this pa tient , uveitis was the initial manifestation and resulted in a systemic diagnosis.

    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.

    Full Text Available 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.

    Full Text Available Dianna Liu, Franz Marie Cruz, Prem S SubramanianWilmer Eye Institute, The Johns Hopkins School of Medicine, Baltimore, Maryland, USAAbstract: 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.Keywords: optic neuropathy, blindness, radiofrequency, vision loss

    A 57-year-old woman underwent an enucleoresection of her right kidney angiomyolipoma. Two weeks later she was admitted to our hospital because of dyspnea at rest with orthopnea. The chest x-ray showed the elevation of both hemidiaphragms and the measurement of the sniff transdiaphragmatic pressure confirmed the diagnosis of bilateral diaphragmatic paralysis. A diaphragm paralysis can be ascribed to several causes, i.e. trauma, compressive events, inflammations, neuropathies, or it can be idiopathic. In this case, it was very likely that the patient suffered from post-surgery neuralgic amyotrophy. To our knowledge, there are only a few reported cases of neuralgic amyotrophy, also known as Parsonage-Turner Syndrome, which affects only the phrenic nerve as a consequence of a surgery in an anatomically distant site.

    Coral reefs are among the most diverse and threatened ecosystems on the planet. The most commonly stated for developing coral reef remote sensing techniques is to asses and or to monitor the status of these ecosystems. The study site was selected one of small island in inner zone Spermonde archipelago, Indonesia. We used Landsat MSS, Landsat TM, Landsat ETM, and Landsat OLI data to examine changes in the coral reefs of inner zone island in the Spermonde Archipelago from 1972 to 2016. The image processing are gap fills, atmospheric correction, geometric corrections, image composites, water column corrections, unsupervised classifications, and reclassification. Some of component change detection procedure was applied to define change. The results showed significant changes in 44 years. Disturbed coral reefs are typically characterized by loss of coral cover by increase in the abundance of dead corals and rubble. Local factors such as destructive fishing is direct destruction of inner zone island. While the impact of local threats may be reduced through management action, global threats to coral reefs are likely to increase in severity in the coming years.

    Recent findings indicate that conscious attention is related to large-scale information integration of various brain regions, including both hemispheres, that enables integration of parallel distributed modalities of processed information. There is also evidence that the level of information transference related to integration or splitting among brain regions, and between hemispheres, establishes a certain level of efficiency of the information processing. The level of information transference also may have modulatory influences on attentional capacity that are closely linked to the emotional arousal and autonomic response related to a stimulus. These findings suggest a hypothesis that changes in conscious attention, specifically during meditation could be reflected in the autonomic activity as the left-right information transference calculated from bilateral electrodermal activity (EDA). With the aim to compare conscious attention during meditation with other attentional states (resting state, Stroop task, and memory task), we performed bilateral EDA measurement in 7 healthy persons during resting state, Stroop task, neurofeedback memory test, and meditation. The results indicate that the information transference (ie, transinformation) is able to distinguish those attentional states, and that the highest level of the transinformation has been found during attentional processing related to meditation, indicating higher level of connectivity between left and right sides. Calculations other than pointwise transinformation (PTI) performed on EDA records, such as mean skin conductance level or laterality index, were not able to distinguish attentional states. The results suggest that PTI may present an interesting method useful for the assessment of information flow, related to neural functioning, that in the case of meditation may reflect typical integrative changes in the autonomic nervous system related to brain functions and focused attentional processing.

    Antecedentes: el linfoma de Burkitt es una forma agresiva de los linfomas no Hodgkin de células B que ocurre con mayor frecuencia en niños y adultos jóvenes; el linfoma de ovario puede aparecer como lesión primaria o, más comúnmente, como una metástasis. Las lesiones primarias de ovario son manifestaciones raras que corresponden a 0.5% de los linfomas no Hodgkin y 1.5% de los tumores de ovario. Caso clínico: paciente femenina de 31 años de edad, con debilidad generalizada, incapacidad para la marcha, disnea, hiporexia, fiebre, diaforesis, pérdida de 20 kg de peso, abdomen plano, con dolor abdominal; Ca125 610 U/mL. La tomografía computada abdominal mostró un gran tumor de aspecto sólido que afectaba a la cavidad pélvica derecha. Se extirparon los tumores ováricos bilaterales. Desde el punto de vista microscópico ambas lesiones muestran una imagen en "cielo estrellado" compuesta por un patrón de infiltrado monótono de linfocitos mezclada con macrófagos de citoplasma amplio y claro, abundantes mitosis atípicas, zonas de necrosis y hemorragia. La inmunohistoquímica reveló positividad para CDI0 y CD20, negativo con CD3, índice de proliferación Ki67 alto. Se diagnosticó linfoma tipo Burkitt bilateral de ovario. Conclusiones: el linfoma de Burkitt de ovario bilateral es poco frecuente, con variabilidad de presentación; el dolor abdominal y los tumores abdominales son lo más frecuente. El pronóstico a corto plazo de las pacientes es malo, por lo que es necesario conocer esta afección para poder establecer el diagnóstico temprano.

    A new engineering technique of calculating the heating and thermal destruction of vessels containing liquid under extreme thermal loading conditions is offered. The heating of the shell and the internal vessel volume is described on the basis of the thermodynamic approach. The pressure growth in a vessel is a result of gas heating and liquid evaporation. Stresses within the shell and its destruction conditions are determined, which allows predicting the critical time of destruction upon heating. The calculation and experimental data for pressure growth inside the vessel are in good agreement.

    Full Text Available Ground lichens constitute a vital part of reindeer winter diet, and non-destructive estimation of lichen biomass is therefore crucial for providing objective data for the management of lichen resources. The aim of this study is to compare precisions of different methods of estimating lichen biomass from ground cover and thallus heights of the four most important lichen species: Cladonia arbuscula, C. rangiferina, C. stellaris, and Cetraria islandica. The methods were validated against actual lichen biomass within 50 cm x 50 cm plots. Different methods gave remarkably similar results, except when cover estimation was based on presence/absence data with a strict criterion of 100% lichen cover. Average thallus heights within the plot explained the variation in lichen biomass as well as lichen volume (estimated from cover and average heights. Relationships between biomass and volume or height were also very similar for all four lichen species, and separation into species thus do not seem necessary for practical purposes.Abstract in Swedish / Sammandrag:Icke-destruktiv skattning av lavbiomassa Marklavar utgör en kritisk del av renars vinterföda, och det blir därmed väsentligt att kunna skatta lavbiomassa på ett icke-destruktivt sätt för att kunna förvalta lavresursen. Syftet med denna studie är att jämföra precisionen hos olika metoder för att skatta lavbiomassa baserat på volym- och bålhöjdsmätningar för de fyra viktigaste arterna: Cladonia arbuscula, C. rangiferina, C. stellaris, and Cetraria islandica. Metoderna validerades mot lavbiomassa mätt i 50 cm x 50 cm provytor. Olika metoder gav anmärkningsvärt lika resultat, förutom när täckning skattades med förekomstdata med ett strikt kriterium av 100% lavförekomst. Medelhöjd på lavbålarna i provytan förklarade lika mycket av variationen i lavbiomassa som lavvolym (baserat på täckning och medelhöjd. Förhållandet mellan biomassa och volym eller bålhöjd var ocks

    Full Text Available Espasmo hemifacial bilateral é um distúrbio de movimento raro geralmente associado à compressão vascular dos nervos faciais. Caracteriza-se clinicamente por contrações assimétricas e assíncronas da musculatura facial e por longa latência entre a instalação dos movimentos em cada hemiface. Deve ser diferenciado de outras condições como blefaroespasmo, miocimia facial, tiques faciais, distonia oromandibular e espasmo hemimastigatório. O tratamento sintomático mais eficaz e menos invasivo consiste em aplicações de toxina botulínica mas abordagem cirúrgica de descompressão microvascular é outra alternativa terapêutica. Relatamos o caso de homem de 70 anos com espasmo hemifacial bilateral e fazemos uma breve revisão da literatura.Bilateral hemifacial spasm (BHS is a rare focal movement disorder often associated with vascular compression of both facial nerves. The contractions are usually asymmetric and asynchronous. Typically, one side is affected first and there is a long but variable interval for the symptoms on the other side to occur. BHS must be differentiated from other conditions including blefarospasm, facial myokymia, facial tics, oromandibular dystonia, and hemimasticatory spasm. The most successful and non-invasive symtomatic treatment is botulinum toxin injections but microvascular decompression surgery is another therapeutic option. We report the case of a 70 years old man with bilateral hemifacial spasms and present a brief review of the literature.

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

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

    2016-03-01

    Full Text Available Objective:To evaluate the different etiologies and clinical subtypes of bilateral vestibular hypofunction (BVH and the value of diagnostic tools in the diagnostic process of BVH.Materials and methods: A retrospective case review was performed on 154 patients diagnosed with BVH in a tertiary referral center, between 2013 and 2015. Inclusion criteria comprised 1 imbalance and/or oscillopsia during locomotion, and 2 summated slow phase velocity of nystagmus of less than 20 degrees per second during bithermal caloric tests.Results:The definite etiology of BVH was determined in 47% of the cases and the probable etiology in 22%. In 31%, the etiology of BVH remained idiopathic. BVH resulted from more than 20 different etiologies. In the idiopathic group, the percentage of migraine was significantly higher compared to the non-idiopathic group (50% versus 11%, p<0.001. Among all patients, 23.4% were known with autoimmune disorders in their medical history. All 4 clinical subtypes (recurrent vertigo with BVH, rapidly progressive BVH, slowly progressive BVH and slowly progressive BVH with ataxia were found in this population. Slowly progressive BVH with ataxia comprised only 4.5% of the cases. The head impulse test was abnormal in 94% of the cases. The torsion swing test was abnormal in 66%. Bilateral normal hearing to moderate hearing loss was found in 49%. Blood tests did not often contribute to the determination of the etiology of the disease. Abnormal cerebral imaging was found in 21 patients.Conclusion:BVH is a heterogeneous condition with various etiologies and clinical characteristics. Migraine seems to play a significant role in idiopathic BVH and auto-immunity could be a modulating factor in the development of BVH. The distribution of etiologies of BVH probably depends on the clinical setting. In the diagnostic process of BVH, the routine use of some blood tests can be reconsidered and a low-threshold use of audiometry and cerebral imaging is

  15. Simultaneous Bilateral Transient Osteoporosis of the Hip without Pregnancy

    Directory of Open Access Journals (Sweden)

    Yasuaki Okada

    2016-01-01

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

    2014-12-01

    Full Text Available The paper discusses the mechanisms of destructive processes in rheumatoid arthritis (RA. At the present stage, in addition to suppress inflammation, the goals of treatment are to prevent cartilage and bone destruction in the affected joints. Prediction of destructive processes in RA plays an important role as the irreversibility of functional changes in RA directly correlates with the degree of joint injury. The paper discusses the mechanisms of articular cartilage and bone destruction and the significance of different biochemical markers for estimating the degree of injury and for predicting further destruction of small hand and foot joints. In RA, the investigators identify not only clinical (activity indicators, but also biological (bone, cartilage, and synovium damage markers predictors for joint injury: CТXII is a marker for cartilage degradation (collagen type II and CTXI is a marker for bone degradation (collagen type I and their trends over 4–12 or more weeks. Although the occurrence of erosions is considered to be a major manifestation of joint destruction progression in RA, the functional activity in its early stages is shown to depend on the estimate of joint space narrowing (cartilage degradation to a greater extent than on that of erosions when evaluating the destruction by the modified Sharp method. Several randomized placebocontrolled studies (RPCSs have assessed the association of patients' functional capacity with joint space narrowing or with the number of erosions. In RA, cartilage degradation has been demonstrated to play a larger role in irreversible function loss than bone destruction.The possibility of suppressing cartilage degradation, which is indicated in RPCSs of the efficacy of adalimumab, correlates with a better functional outcome in patients with RA. Serum markers for cartilage metabolism may be not only predictors for further radiographic progression, but also be used to evaluate therapeutic effectiveness.

    Over the past 70 years, various actors have dramatically reconfigured the Las Vegas Strip in many forms. I claim that behind the Strip's "reinventions" lies a process of symbolic destruction. Since resorts distinguish themselves symbolically, each new round of capital accumulation relies on the destruction of symbolic capital of existing resorts. A new resort either ups the language within a paradigm, or causes a paradigm shift, which devalues the previous resorts even further. This is why, i...

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

    2015-12-01

    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.

    The injection of a high viscosity fluids into the tissues for cosmetic body contouring has been practised in the last four decades in the East and South-East of Asia. The injection of liquid paraffin for mammary augmentation was widely practised by surgeons, physician and even non medical people. Unfortunately, most of these cases ended by having different varieties of paraffinoma as a complication of a foreign body reaction. We report three cases of a destructive form of these paraffinomas ulcerating into both breasts and the anterior chest wall. One case was treated by bilateral mastectomy, radical excision of the anterior chest wall soft tissue and reconstruction by a vertical Rectus Abdominus Myocutaneous Flap. The second case had bilateral mastectomy and followed up for facial paraffinomas. The third case was just followed for up regular wound care as surgery was not indicated due to advanced age, poor general condition and the family request.

    2017-04-01

    The combination of semi-destructive and non-destructive methods was used to asset the conditions of a tiled floor in the historical monument Minaret, situated in the park complex of the Chateau Lednice (South Moravia Region, Czech Republic), before its renovation. Another set of measurements is going to be performed after the conservation works are finished. (The comparison of the results collected during pre- and post-remediation measurements will be known and presented during the General Assembly meeting in Wien.) The diagnostic complex of methods consisted of photogrammetry, resistivity drilling and georadar. The survey was aimed to contour extends of air gaps beneath the tiles and the efficiency of filling gaps by means of injection, consolidation and gluing individual layers. The state chateau Lednice creates a part of the Lednice-Valtice precinct, a UNESCO landmark, and belongs among the greatest historic monuments in Southern Moravia. In the chateau park there is a romantic observation tower in the shape of a minaret built according to the plans of Josef Hardtmuth between 1798-1804. The Minaret has been extensively renovated for many decades including the restoration of mosaic floors from Venetian terazzo. During the static works of the Minaret building between 1999-2000, the mosaic floors in the rooms on the second floor were transferred and put back onto concrete slabs. Specifically, the floor was cut up to tiles and these were glued to square slabs which were then attached to the base plate. The transfer was not successful and the floor restoration was finalized between 2016-2017. The damage consisted in separating the original floor from the concrete plate which led to creating gaps. Furthermore, the layers of the floor were not compact. It was necessary to fill the gaps and consolidate and glue the layers. The existence of air gap between individual layers of the tiles and their degradation was detected using two different diagnostic methods: semi-destructive

  18. The results of cutting disks testing for rock destruction

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available To determine the rational order of disk tools placement on the working body is necessary to know the maximum amount of rock, destroyed by the disk tool in benching cutting mode depending on the tool geometry parameters, physical and mechanical parameters of rocks. The article contains the definition of rational parameters of cutting disk tools as well as power and energy parameters of the destruction process by cutting disks and by executive body of the coal cutter. The rational geometric parameters of cutting discs are specified. It was found that each step of cutting with a minimum depth of penetration has its own maximum height of bench outcrop. The dependence of the volumes of large items destroyed by the disk tool on the cutting step height was determined. The existence of the cyclic alternation of destruction phases, regardless the fracture parameters, the height of the ledge outcrop, and tools like free cutting geometry were found. In contrast to the free cutting in benching mode of destruction two large fragments of rocks in one cycle were observed. Consequently, the cyclical nature of the destruction process in the benching mode will be characterized by two chips and crushing, and this cycling repeats throughout the destruction process with the same parameters of destruction.

    The cholinergic innervation of the interpeduncular nucleus (IPN) is wholly extrinsic and is greatly attenuated by bilateral habenular destruction. We describe changes in the labeling of putative nicotinic receptors within this nucleus at 3, 5, or 11 days after bilateral habenular lesions. Adjacent tissue sections of the rat IPN were utilized for /sup 3/H-nicotine and /sup 125/I-alpha-bungarotoxin (/sup 125/I-BTX) receptor autoradiography. Compared to sham-operated controls, habenular destruction significantly reduced autoradiographic /sup 3/H-nicotine labeling in rostral (-25%), intermediate (-13%), and lateral subnuclei (-36%). Labeling in the central subnucleus was unchanged. Loss of labeling was maximal at the shortest survival time (3 days) and did not change thereafter. In order to establish whether this loss was due to a reduction in the number or the affinity of /sup 3/H-nicotine-binding sites, a membrane assay was performed on microdissected IPN tissue from rats that had received surgery 3 days previously. Bilateral habenular lesions produced a 35% reduction of high-affinity /sup 3/H-nicotine-binding sites, with no change in binding affinity. Bilateral habenular lesions reduced /sup 125/I-BTX labeling in the intermediate subnuclei, and a slight increase occurred in the rostral subnucleus. In the lateral subnuclei, /sup 125/I-BTX labeling was significantly reduced (27%) at 3 days but not at later survival times. In view of the known synaptic morphology of the habenulointerpeduncular tract, it is concluded that a subpopulation of /sup 3/H-nicotine binding sites within the IPN is located on afferent axons and/or terminals. This subpopulation, located within rostral, intermediate, and lateral subnuclei, may correspond to presynaptic nicotinic cholinergic receptors. Sites that bind /sup 125/I-BTX may include a presynaptic subpopulation located in the lateral and possibly the intermediate subnuclei.

    Full Text Available Sinonasal undifferentiated carcinoma-related rhinogenic optic neuropathy is rare and may lead to visual loss. To the best of our knowledge, this is the first report of bilateral sequential visual loss induced by this etiology. It is important to differentiate between chronic sinusitis and malignancy on the basis of specific findings on magnetic resonance images. Surgical decompression with multidisciplinary therapy, including steroids, chemotherapy, and radiotherapy, is indicated. However, no visual improvement was noted in this case, emphasizing the rapid disease progression and importance of early diagnosis and treatment.

    Botton, CE, Radaelli, R, Wilhelm, EN, Rech, A, Brown, LE, and Pinto, RS. Neuromuscular adaptations to unilateral vs. bilateral strength training in women. J Strength Cond Res 30(7): 1924-1932, 2016-Considering the bilateral deficit, the sum of forces produced by each limb in a unilateral condition is generally greater than that produced by them in a bilateral condition. Therefore, it can be speculated that performing unilateral strength exercises may allow greater training workloads and subsequently greater neuromuscular adaptations when compared with bilateral training. Hence, the purpose of this study was to compare neuromuscular adaptations with unilateral vs. bilateral training in the knee extensor muscles. Forty-three recreationally active young women were allocated to a control, unilateral (UG) or bilateral (BG) training group, which performed 2 times strength training sessions a week for 12 weeks. Knee extension one repetition maximum (1RM), maximal isometric strength, muscle electrical activity, and muscle thickness were obtained before and after the study period. Muscle strength was measured in unilateral (right + left) and bilateral tests. Both UG and BG increased similarly their unilateral 1RM (33.3 ± 14.3% vs. 24.6 ± 11.9%, respectively), bilateral 1RM (20.3 ± 6.8% vs. 28.5 ± 12.3%, respectively), and isometric strength (14.7 ± 11.3% vs. 13.1 ± 12.5%, respectively). The UG demonstrated greater unilateral isometric strength increase than the BG (21.4 ± 10.5% vs. 10.3 ± 11.1%, respectively) and only the UG increased muscle electrical activity. Muscle thickness increased similarly for both training groups. Neither group exhibited pretesting 1RM bilateral deficit values, but at post-testing, UG showed a significant bilateral deficit (-6.5 ± 7.8%) whereas BG showed a significant bilateral facilitation (5.9 ± 9.0%). Thus, performing unilateral or bilateral exercises was not a decisive factor for improving morphological adaptations and bilateral

    Full Text Available CONTEXT: Electrical burns are an important etiology in dealing with patients suffering from burns. In situations of extensive deep lesions of multiple organs and systems affecting young and economically active people, there is a need for expensive multidisciplinary treatment, with a high socioeconomic cost for the community. Among the permanent injuries that explain this high cost, eye injuries stand out, since they are widely disabling. Although rare, lesions of the posterior segment of the eye are associated with higher incidence of major sequelae, and thus deserve special attention for dissemination and discussion of the few cases observed.CASE REPORT: The authors report the case of a patient who suffered high-voltage electrical burns and presented bilateral maculopathy, which evolved with a need for a surgical approach to repair retinal detachment and permanent low visual acuity.CONCLUSION: This report highlights the rarity of the etiology of maculopathy and the need for campaigns for prevention not only of burns in general, but also especially of electrical burns.

    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.

    Full Text Available Background. The challenge in managing patients undergoing renal transplantation is how to achieve optimum levels of anticoagulation to avoid both clotting and postoperative bleeding. We report a rare case of severe postoperative retroperitoneal bleeding including psoas haematomata complicating renal transplantation. Case Report. SM, a 55-year-old female, had a past history of aortic valve replacement, cerebrovascular event, and thoracic aortic aneurysm and was on long-term warfarin that was switched to enoxaparin 60 mg daily a week prior to her living donor transplantation. Postoperatively, she was started on a heparin infusion, but this was complicated by a large retroperitoneal bleed requiring surgical evacuation on the first postoperative day. Four weeks later, she developed features compatible with acute femoral neuropathy and a CT scan revealed bilateral psoas haematomata. Following conservative management, she made steady progress and was discharged home via a community hospital 94 days after transplantation. At her last visit 18 months after transplantation, she had returned to full fitness with excellent transplant function. Conclusion. Patients in established renal failure who require significant anticoagulation are at increased risk of bleeding that may involve prolonged hospitalisation and more protracted recovery and patients should be carefully counselled about this.

    Full Text Available Background. This case highlights the importance of recognising multiple pathologies within the eye which may not necessarily be linked. Both birdshot retinochoroiditis and astrocytoma are rare conditions. The case underlines the need for early identification and treatment of birdshot retinochoroiditis with steroids and disease modifying drugs. Astrocytoma in the absence of tuberous sclerosis is also uncommon. Case Presentation. A 36-year-old male presented with 3-month history of bilateral progressive flashing lights and floaters. He was systemically well with no significant past medical history. Fundal examination revealed retinal vasculitis and active creamy lesions in the choroid radiating from the optic nerve. In the supranasal periphery of the right eye there was a raised white, jagged lesion protruding into the vitreous. Fluorescein angiogram and indocyanine green showed marked venous vasculitis, hypofluorescence, and disc leakage in keeping with birdshot retinochoroiditis. The supranasal lesion features were in keeping with astrocytoma and this was thought to be a coincidental finding. Conclusions. Retinal astrocytoma may be present as an isolated ocular finding; however, patients must still be investigated for tuberous sclerosis which is the most common association. Birdshot retinochoroiditis typically responds well to steroid therapy, and disease modifying drugs should be considered as soon as possible.

    Objective:To observe the influence of electrolytic destruction of nucleus solitary tract (NTS) and hypothalamic paraventricular nucleus (PVN) on the effect of electroacupuncture (EA) in improving ischemic myocardia cellular transmembrane action potential (TMAP). Methods: 38 Japanese breed big-ear white rabbits (anesthetized with 20% Urethane, 4mL/kg) were randomly divided into acute myocardial ischemia (AMI) group (n=8), PVN destruction group (n=12) and PVN+NTS destruction group (n=18). AMI model was established by occlusion of the descending anterior branch (DAB) of the coronary artery. TMAP of myocytes was recorded by using a glass microelectrode which was fixed to a suspending spring silver wire. Bilateral "Neiguan"(PC 6) in all the 3 groups were punctured and stimulated electrically by using parameters of continuous waves, frequency ECG-ST elevated significantly while APA lowered, APD50 and APD90 shortened of 7 Hz, intensity of 6 mA and duration of 30 minutes. Results: After AMI,clearly in comparison with those of pre-AMI in the 3 groups. Compared with AMI group, ECG-ST values of PVN destruction group and PVN+NTS destruction group were significantly higher (P<0.05~0.01), while APA, APD50 and APD90 all significantly lower in all the recording time courses(P<0.05). The facts displayed that electrolytic destruction of PVN and PVN+NTS could produce ischemic myocardial injury and reduce the protective effect of EA on ischemic myocardial cells. Comparison between PVN destruction and PVN+NTS groups showed that all the 4 indexes of the later group were evidently worse than those of the former group (P<0.05), suggesting after destruction of these two nuclei, the effect of EA was worsened further. Conclusion: Electrolytic destruction of PVN and NTS weakens the protective effect of EA on ischemic myocardial cells, both NTS and PVN take part in the effect of EA of "Neiguan"(PC 6) Point in improving ischemic myocardium.

    We address the possibility that intelligent civilizations that destroy themselves could present signatures observable by humanity. Placing limits on the number of self-destroyed civilizations in the Milky Way has strong implications for the final three terms in Drake's Equation, and would allow us to identify which classes of solution to Fermi's Paradox fit with the evidence (or lack thereof). Using the Earth as an example, we consider a variety of scenarios in which humans could extinguish their own technological civilization. Each scenario presents some form of observable signature that could be probed by astronomical campaigns to detect and characterize extrasolar planetary systems. Some observables are unlikely to be detected at interstellar distances, but some scenarios are likely to produce significant changes in atmospheric composition that could be detected serendipitously with next-generation telescopes. In some cases, the timing of the observation would prove crucial to detection, as the decay of signatures is rapid compared with humanity's communication lifetime. In others, the signatures persist on far longer timescales.

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

    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.

    Puerarin, the most abundant isoflavonoid in kudzu root, shows various bioactivities, including bone-sparing, anti-inflammatory and antiproteinase properties. This study aimed to evaluate the effects of puerarin in a rat model of ligature-induced periodontitis. Rat models of periodontitis were developed by bilaterally placing ligatures around the first mandibular molars. Puerarin was administrated daily by gavage at doses of 100, 200 and 400 mg/kg, starting a day before the placement of ligatures. Rats were humanely killed 7 d after the induction of periodontitis. Micro-computed tomography and sirius red staining were used to evaluate alveolar bone loss and collagen destruction, respectively. Histomorphometrical analysis was used to assess the inflammatory cell infiltration. Immunohistochemistry and tartrate-resistant acid phosphatase were used to detect receptor activator of nuclear factor kappa B ligand and osteoprotegerin expressions, and osteoclast activity in the gingiva and alveolar bone. The activation of nuclear factor-kappa B, production of tumor necrosis factor (TNF)-α and interleukin (IL)-1β, glycosylation of extracellular matrix metalloproteinase inducer, and production of matrix metalloproteinase (MMP)-2 and MMP-9 in the gingiva were assessed by Western blot. Puerarin at doses of 200 and 400 mg/kg significantly reduced the alveolar bone loss compared with the vehicle group. Collagen destruction and inflammatory cell infiltration were significantly less in the puerarin-treated group (200 mg/kg) compared with that of the vehicle group. Puerarin (200 mg/kg) also reduced the ratio of receptor activator of nuclear factor kappa B ligand/osteoprotegerin and osteoclast activity. Western blot analysis showed that puerarin (200 mg/kg) inhibited the activation of nuclear factor-kappa B p65, which is associated with lower IL-1β and TNF-α production, and reduced the glycosylation of extracellular matrix metalloproteinase inducer, which is associated with lower

A grande maioria desses casos ocorre unilateralmente. Em setembro de 2004, um homem de 43 anos chegou ao pronto-socorro do Hospital Universitário de Santa Maria (HUSM com queixa de dor bilateral no ombro e incapacidade de abaixar os braços, em consequência de uma queda com os braços abduzidos, enquanto desempenhava sua atividade laboral. Após o exame físico e radiológico constatou- se que o indivíduo apresentava uma luxação inferior bilateral dos ombros. O paciente foi então encaminhado ao bloco cirúrgico onde foi realizada redução incruenta das luxações sob anestesia através da técnica de tração e contra-tração. No dia seguinte recebeu alta com imobilização tipo Velpeau mantendo os ombros totalmente aduzidos e rotados internamente, com orientação de manter a imobilização por três semanas.
