Full Text Available The flood after a typhoon may lead to increase in patients with cellulitis of lower limbs. However, the microbiological features of these cases are rarely reported. We conducted a study of patients with lower extremity cellulitis after a typhoon followed in southern Taiwan to study the risk factors of cellulitis and the bacteriological features of the patients.We reviewed all the medical records of cellulitis at emergency departments of two teaching hospitals in southern Taiwan 30 days before and after the landing of Typhoon Morakot and collected data on the demographic and bacteriological characteristics. In addition, we evaluated the relationship between the daily number of patients and the rainfall in the Tainan area.The number of cellulitis patients increased from 183 to 344 during the 30-day period after the typhoon. The number peaked in the third and fourth days and lasted for 3 weeks. The proportion of patients with water immersion of the affected limb was higher after the typhoon (6% vs. 37%, odds ratio [OR]: 9.0, 95% Confidence interval [CI]: 4.7-17.2. We found cultures from the infected limbs with immersion had more polymicrobial (73% vs. 26%, OR: 7.8, 95% CI: 3.2-19.2 and Gram-negative bacilli infection (86% vs. 34%, OR: 11.8, 95% CI: 4.1-34.5.Flood arose from Typhoon Morakot caused increases in cellulitis patients, which lasted for 3 weeks. Antibiotic treatment that were effective to both Gram-positive cocci and Gram-negative bacilli are recommended for patients with limbs emerged in the water.

The aim of this study was to assess the use of magnetic resonance as a new method for evaluating the manual lymphatic drainage technique in treating cellulitis. Cellulitis is one of the main esthetic problems that lead women toward seeking guidance and specific treatments. There are various therapeutic approaches, owing to the multifactorial nature of its pathogen, although the effectiveness of most of these has not been definitively proven, given that the assessment methods used are mostly subjective or do not provide enough information on subcutaneous tissue. The introduction of magnetic resonance as a means of assessing a lymphatic drainage technique in cellulitis treatment makes the evaluation more accurate, since it enables a detailed study of subcutaneous architecture.

2010-10-01

Limited data exist on optimal empiric oral antibiotic treatment for outpatients with cellulitis in areas with a high prevalence of community-associated methicillin-resistant Staphylococcus aureus (MRSA) infections. We conducted a 3-year retrospective cohort study of outpatients with cellulitis empirically treated at a teaching clinic of a tertiary-care medical center in Hawaii. Patients who received more than 1 oral antibiotic, were hospitalized, or had no follow-up information were excluded. Treatment success rates for empiric therapy were compared among commonly prescribed antibiotics in our clinic: cephalexin, trimethoprim-sulfamethoxazole, and clindamycin. Risk factors for treatment failure were evaluated using multivariate logistic regression analysis. Of 544 patients with cellulitis, 405 met the inclusion criteria. The overall treatment success rate of trimethoprim-sulfamethoxazole was significantly higher than the rate of cephalexin (91% vs 74%; P<.001), whereas clindamycin success rates were higher than those of cephalexin in patients who had subsequently culture-confirmed MRSA infections (P=.01), had moderately severe cellulitis (P=.03), and were obese (P=.04). Methicillin-resistant S. aureus was recovered in 72 of 117 positive culture specimens (62%). Compliance and adverse drug reaction rates were not significantly different among patients who received these 3 antibiotics. Factors associated with treatment failure included therapy with an antibiotic that was not active against community-associated MRSA (adjusted odds ratio 4.22; 95% confidence interval, 2.25-7.92; P<.001) and severity of cellulitis (adjusted odds ratio 3.74; 95% confidence interval, 2.06-6.79; P<.001). Antibiotics with activity against community-associated MRSA, such as trimethoprim-sulfamethoxazole and clindamycin, are preferred empiric therapy for outpatients with cellulitis in the community-associated MRSA-prevalent setting.

Full Text Available Military trainees are at high risk for skin and soft-tissue infections (SSTIs. Although Staphylococcus aureus is associated with purulent SSTI, it is unclear to what degree this pathogen causes nonpurulent cellulitis. To inform effective prevention strategies and to provide novel insights into SSTI pathogenesis, we aimed to determine the etiology of SSTI in this population. We conducted a prospective observational study in US Army Infantry trainees with SSTI (cutaneous abscesses and cellulitis from July 2012 through December 2014. We used standard microbiology, serology, and high-throughput sequencing to determine the etiology of SSTI. Furthermore, we compared purported risk factors as well as anatomic site colonization for S. aureus. Among 201 SSTI cases evaluated for SSTI risk factors, cellulitis was associated with lower extremity blisters (P = 0.01 and abscess was associated with methicillin-resistant S. aureus (MRSA colonization (P<0.001. Among the 22 tested cellulitis cases that were part of the microbiome analysis, only 1 leading edge aspirate was culturable (Coagulase-negative Staphylococcus. Microbiome evaluation of aspirate specimens demonstrated that Rhodanobacter terrae was the most abundant species (66.8% average abundance, while abscesses were dominated by S. aureus (92.9% average abundance. Although abscesses and cellulitis share the spectrum of clinical SSTI, the bacterial etiologies as determined by current technology appear distinct. Furthermore, the presence of atypical bacteria within cellulitis aspirates may indicate novel mechanisms of cellulitis pathogenesis.NCT01105767.

The study aimed to assess characteristics of facial cellulitis admissions and their relationship to cost of hospitalization (COH) and length of stay (LOS) in children ages 0 to 20 years at an urban hospital and to compare outcomes of rapid management to published and national statistics for LOS and COH. A retrospective review of 376 charts of facial cellulitis admissions between 2000 and 2006 revealed 63 of confirmed odontogenic cases from which cellulitis characteristics, COH, and LOS were gleaned. Variables were correlated to LOS and COH. Data on LOS and cost of admission were compared to published studies and 506 entries from the 2006 Kids' Inpatient Database (KID). Of 63 charts included, children included were 8.3 years (SD, +/-3.8 years) and equal in sex distribution. Treatment rendered and site of infection had no significant relationship to COH. Overall mean hospital LOS was 2.08 days and significantly less as compared to 3.97 days for published studies and 3.4 days for KID (P KID. In the management of pediatric facial cellulitis of odontogenic origin, rapid treatment had a significant positive impact on length of stay and total cost of treatment compared to published studies and nationally reflective data.

A suspected dental cellulitis leading to diagnosis of both herpes zoster ophthalmicus and HIV

Directory of Open Access Journals (Sweden)

Grace E. Parkins, BDS, FDS.RCPS (Glas., FWACS, FGCS

2015-03-01

Full Text Available Herpes zoster ophthalmicus and HIV are serious health problems. We report a case of a 37-year-old woman who presented to the Korle-Bu Teaching Hospital with dyspnea and facial cellulitis, and a diagnosis 5 days prior of dental cellulitis made at a district hospital. Investigations revealed that the facial cellulitis was secondary to herpes zoster infection involving the ophthalmic division of the left trigeminal nerve. The patient responded well to oral acyclovir but developed postherpetic neuralgia. During the course of treatment, she was also diagnosed to be HIV-1 positive and was referred for further management. This case represents a unique report in which the patient presented to the hospital with symptoms of cellulitis suggestive of underlying dental infection but was later diagnosed with both herpes zoster ophthalmicus and an underlying HIV infection. Atypical presentations of herpes zoster can occur in HIV/AIDS. Signs of herpes zoster infection with cellulitis should alert the clinician that the patient may have a possible underlying immunosuppressive disease. The population must be educated regarding the importance of early presentation and careful compliance with treatment as well as regular follow-ups.

2007-01-01

Full Text Available Bergeyella zoohelcum is a rod-shaped, aerobic, Gram-negative, non-motile and non-saccharolytic bacterium. It is frequently isolated from the upper respiratory tract of dogs, cats and other mammals. Clinically, B. zoohelcum has been known to cause cellulitis, leg abscess, tenosynovitis, septicemia, pneumonia and meningitis, and is associated with animal bites. In addition, food-borne transmission was considered in a recent case report. We report a 73-year-old man with liver cirrhosis who had no history of dog bite but had dog exposure, who developed cellulitis of the left lower leg and B. zoohelcum was isolated from blood culture. This patient, without evidence of polymicrobial infection, was treated with cefazolin and gentamicin with a good outcome. B. zoohelcum is a zoonotic pathogen that may cause bacteremia in patients with underlying disease such as liver cirrhosis; it can be treated with a beta-lactam or quinolone.

Full Text Available Orbital cellulitis is an infection of soft tissue behind the orbital septum. Common pathogens isolated include Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus pneumoniae. It is a straightforward diagnosis and usually responds to empirical treatment without any sequela. We report a case of orbital cellulitis caused by Enterococcus faecalis, which was complicated by myositis of levator palpebrae superioris. To the best of our knowledge, only one case report exists dating way back to 1986.

There is some evidence to suggest that host inflammatory response has some effect on the clinical manifestations of cellulitis. The objective of this pilot study was to investigate whether the addition of oral nonsteroidal anti-inflammatory (NSAI) therapy to antibiotic treatment hastens resolution of cellulitis-related inflammation. Patients presenting in the emergency department with signs and symptoms of class II cellulitis were assigned to receive treatment with either antibiotic therapy alone (intravenous, supplemented with oral cephalexin or an equivalent) for 10 days (n = 33) or antibiotic therapy for 10 days plus an oral anti-inflammatory (ibuprofen 400 mg every 6 hours) for 5 days (n = 31). Patients were discharged as soon as possible to complete their therapy on an outpatient basis. The addition of an oral anti-inflammatory agent significantly (P < .05) shortened the time to regression of inflammation and complete resolution of cellulitis. Twenty-four of 29 evaluable patients (82.8%) who received supplemental anti-inflammatory treatment showed regression of inflammation within 1 to 2 days compared with only 3 of 33 patients (9.1%) treated without an anti-inflammatory in the same time frame. All patients receiving adjunctive anti-inflammatory treatment experienced complete resolution of cellulitis in 4 to 5 days or less, while 24.2% (8/33) of patients treated with antibiotic alone required 6 to 7 days, and 6.1% (2/33) required 7 days or more (P < .05). This small preliminary study provides some promising data, suggesting that the supplemental use of anti-inflammatory therapy may hasten the time to regression of inflammation and complete resolution of cellulitis.

Improving accuracy of ET measurement of LISS nozzle to calandria tube clearance

International Nuclear Information System (INIS)

Craig, S.T.; Krause, T.W.; Schankula, J.J.

2006-01-01

The AECL Fuel Channel Inspection System (AFCIS) has been used in an in-reactor field trial to successfully measure the clearance between Liquid Injection Shutdown System (LISS) nozzles and calandria tubes. Each measurement over the full length of a channel added only 15 minutes to the on-channel inspection time. No changes were required to the inspection heads. The only equipment changes made were the addition of a Remote Field Eddy Current (RFEC) module to the eddy current instrument, and minor wiring changes, at the instrument, to achieve a RFEC configuration. With the experience gained from the field trial, factors potentially limiting accuracy were identified. These, and other factors, were investigated and are discussed herein. The RFEC probe is delivered inside the pressure tube. Magnetic fields from the RFEC probe extend through the conducting walls of the pressure tube and calandria tube to interact with the LISS nozzle. Data acquired during the field trial showed the LISS nozzle signal is distinct and the signal-to-noise ratio is very favourable. Nevertheless, comparison of the RFEC measurements to a visual examination, made during the same outage, had the RFEC method underestimating the clearance by 2.5 mm on average. By way of laboratory tests, the following factors were investigated as potential sources of error: resistivity and geometry of LISS nozzle reference/calibration pieces, pressure-tube wall thickness, diameter and resistivity variations, pressure-tube to calandria-tube gap, and radial offsets of the probe within the pressure-tube. The sensitivity to these various noise sources was established. A model, based on fundamental electromagnetic principles, was developed and was used to normalize the effects of LISS nozzle conductivity and geometry. This enabled compensation for various sources of error, and made it possible to produce a correction factor for the field trial data, reducing the average difference from the visual inspection of LISS

Cellulitis is an unusual presentation of cryptococcal infection in renal allograft recipients. In such patients, disseminated cryptococcal infection can result in significant morbidity and mortality. Patients are often treated with antibiotics before a definitive diagnosis is made, delaying appropriate therapy. We describe the case of a 43-year-old post renal transplant recipient presenting with fever and swelling in the right thigh. On physical examination, the patient was found to have features suggestive of cellulitis with minimal slurring of speech. Material obtained from incision and drainage of the wound showed yeast cells resembling Cryptococcus spp. Blood culture and cerebrospinal fluid culture were also found to have growth of Cryptococcus neoformans. He received treatment with amphotericin B 6 mg/kg daily intravenously for two weeks, then continued with fluconazole 400 mg daily for three months. The patient showed a remarkable improvement. There was no recurrence of cryptococcosis after four months of follow-up. The diagnosis of disseminated cryptococcosis should be considered in differential diagnosis of cellulitis among non HIV immunocompromised hosts. A high clinical suspicion and early initiation of therapy is needed to recognize and treat patients effectively.

[Orbital cellulitis complicated by subperiosteal abscess due to Streptococcus pyogenes infection].

Science.gov (United States)

Ruíz Carrillo, José Daniel; Vázquez Guerrero, Edwin; Mercado Uribe, Mónica Cecilia

Orbital cellulitis is an infectious disease that is very common in pediatric patients, in which severe complications may develop. Etiological agents related to this disease are Haemophilus influenzae B, Staphylococcus aureus, Streptococcus pneumoniae and Moraxella catarrhalis, which correspond to 95% of cases. Moreover, Streptococcus beta hemolytic and anaerobic microorganisms may also be present corresponding to < 5% of the cases. We present an uncommon case of cellulitis complicated by sub-periosteal abscess caused by Streptococcus pyogenes (Group A beta hemolytic streptococcus). A 9-year-old male patient with a history of deficit disorder and hyperactivity since 5 years of age. His current condition started with erythema in the external edge of the right eye, increase in peri-orbicular volume with limitation of eyelid opening, progression to proptosis, pain with eye movements and conjunctival purulent discharge. Image studies reported subperiosteal abscess and preseptal right with extraocular cellulitis. The patient started with empirical antibiotic treatment, surgical drainage and culture of purulent material from which Streptococcus pyogenes was isolated. Due to the implementation of vaccination schemes against H. influenza and S. pneumoniae since the 90s, the cases by these pathogens have decreased, causing new bacteria to take place as the cause of the infection. The importance of considering S. pyogenes as an etiology of orbital cellulitis is the rapid progression to abscess formation, and the few cases described in the literature.

2013-10-01

Full Text Available Introduction: Orbital pseudotumor, also known as idiopathic orbital inflammatory syndrome (IOIS, is a benign, non- infective inflammatory condition of the orbit without identifiable local or systemic causes. The disease may mimics a variety of pathologic conditions. We pre-sent a case of pseudotumor observed in a patient admitted under the name of orbital celluli-ties. Case Report: A 26-year-old woman reffered to our hospital with the history of left ocular pain and headache 2 days before her visit.. Ophthalmological examination of the patient was normal except for the redness and lid edema, mild chemosis and conjunctival injection. Gen-eral assessment was normal but a low grade fever was observed. She was hospitalized as an orbital cellulitis patient. She was treated with intravenous antibiotics. On the third day , sud-denly diplopia, proptosis in her left eye and ocular pain in her right side appeared. MRI re-vealed bilateral enlargement of extraocular muscles. Diagnosis of orbital pseudotumor was made and the patient was treated with oral steroid.She responded promptly to the treatment. Antibiotics were discontinued and steroid was tapered in one month period under close fol-low up. Conclusion: The clinical features of orbital pseudotumor vary widely . Orbital pseudotumor and orbital cellulitis can occasionally demonstrate overlapping features.. Despite complete physical examination and appropriate imaging, sometimes correct diagnosis of the disease would be difficult (Sci J Hamadan Univ Med Sci 2013; 20 (3:256-259

2009-03-01

Orbital cellulitis is conventionally managed by intravenous (i.v.) antibiotic therapy, followed by oral antibiotics once the infection shows signs of significant improvement. We report 4 years of experience using primary oral ciprofloxacin and clindamycin in cases of orbital cellulitis. Oral ciprofloxacin and clindamycin have a similar bioavailability to the i.v. preparations and provide an appropriate spectrum of antibiotic cover for the pathogens responsible for orbital cellulitis. A retrospective review was performed that identified all patients with orbital cellulitis and treated with primary oral antibiotic therapy admitted to the Manchester Royal Eye Hospital between March 2003 and March 2007. Age, stage of disease, surgical intervention, hospital duration, and complications were obtained. A comparison was made with patients admitted to our unit with orbital cellulitis and treated with primary i.v. antibiotics between March 2000 and March 2003. Nineteen patients were included in the review for the period March 2003 to March 2007, which comprised of 7 children and 12 adults. Five patients required surgical intervention. All patients responded to the oral regimen, 18 patients had no change to their oral antibiotic therapy. Mean hospital stay was 4.4 days. There were no complications. Empirical oral ciprofloxacin and clindamycin combination may be as safe and effective as i.v. therapy in the management of orbital cellulitis. Oral treatment can offer the advantages of rapid delivery of the first antibiotic dose, fewer interruptions in treatment, and simplified delivery of medication particularly in children.

Necrotizing cellulitis of dental origin is a serious disease and requires prompt and effective management to avoid adverse outcomes. The purpose of this work is to describe the diagnostic and therapeutic difficulties encountered in this condition. This was a prospective study in the thoracic surgery department of Mali Hospital from January 2011 to February 2015. We collected consecutively 19 cases of complicating cervico-facial cellulitis of dental origin. The anatomical and clinical aspects, therapeutic modalities and difficulties are described. Dental pain and fever were the predominant symptoms followed by cervical edema. Chest CT-scan was the basis for the diagnosis in all cases. Cervicotomy with debridement was the most performed surgical procedure. Pleural drainage was performed in 6 cases. Three patients (15.8%) died. Necrotizing cellulitis of dental origin is a serious disease with high morbidity and mortality. The key radiological examination is the thoracic CT-scan. Early medico-surgical management by emergency care, tailored antibiotic therapy, removal of necrotizing tissues and drainage of collections are required to deliver a good outcome.

Banana is one of the major crops of India with increasing export potential. It is important to estimate the production and acreage of the crop. Thus, the present study was carried out to evolve a suitable methodology for estimating banana acreage. Area estimation methodology was devised around the fact that unlike other crops, the time of plantation of banana is different for different farmers as per their local practices or conditions. Thus in order to capture the peak signatures, biowindow of 6 months was considered, its NDVI pattern studied and the optimum two months were considered when banana could be distinguished from other competing crops. The final area of banana for the particular growing cycle was computed by integrating the areas of these two months using LISS III data with spatial resolution of 23m. Estimated banana acreage in the three districts were 11857Ha, 15202ha and 11373Ha for Bharuch, Anand and Vadodara respectively with corresponding accuracy of 91.8%, 90% and 88.16%. Study further compared the use of LISS IV data of 5.8m spatial resolution for estimation of banana using object based as well as per-pixel classification and the results were compared with statistical reports for both the approaches. In the current paper we depict the various methodologies to accurately estimate the banana acreage.

2013-10-01

To evaluate the effectiveness of a replating technique having a less-invasive stabilization system (LISS) for femoral shaft fractures due to LISS failure in adults. There were 11 patients with hardware failure of LISS for femoral shaft fractures, on an average of 50 days after the primary operation. The failed implants were removed, and the fractures were replated with a LISS following the rationale of biological osteosynthesis. Radiological fracture union and incidence of postoperative complications were employed to evaluate the effectiveness of this replating technique for femoral shaft fractures. Operative duration including removing failed hardware and replating fractures averaged 81.5 min, with an average blood loss of 330 ml. Patients had an average follow-up of 25.7 months. Radiological evaluation indicated that fracture union occurred in an average of 4.4 months in all patients. The length and alignment of the affected limb were satisfactory, and hardware failure did not recur. The replating technique with LISS for femoral shaft fractures due to hardware failure of LISS can obtain satisfactory results when the appropriate rationale of biological osteosynthesis and functional exercise is followed.

Full Text Available Avian cellulitis is an inflammatory process in the subcutaneous tissue, mainly located in the abdomen and thighs. This problem is commonly observed in poultry at slaughter and it is considered one of the major causes of condemnation of carcasses in Brazil. The aim of this study was to perform the microbial isolation of lesions of avian cellulitis from a processing plant located in the State of Goiás in order to analyze antimicrobial resistance by antibiogram test and to detect resistance genes by polymerase chain reaction. A total of 25 samples of avian cellulitis lesions were analyzed, from which 30 bacterial strains were isolated. There were eleven (44% strains of Escherichia coli, nine (36% strains of Staphylococcus epidermidis, seven (28% strains of Proteus mirabilis and three (12% strains of Manheimiahaemolytica. The antibiogram test showed that all strains were resistant to at least one antimicrobial. The gene of antimicrobial resistance tetB was detected in E. coli, S. epidermidis and P. mirabilis strains, and was the most frequently observed gene. The gene of antimicrobial resistance Sul1 was detected in all bacterial species, while tetA was found in E. coli and S. epidermidis strains, SHV in E. coli strains, S. epidermidis and P. mirabilis,and cat1 in one P. mirabilis strain. The results suggest a potential public health hazard due to the ability of these microorganisms to transmit antimicrobial resistancegenes to other microorganisms present in the intestinal tract of humans and animals, which may affect clinical-medical usage of these drugs.

Cellulitis Secondary to Liquid Nitrogen Cryotherapy: Case Report and Literature Review.

Science.gov (United States)

Huang, Christina M; Lu, Emily Y; Kirchhof, Mark G

Liquid nitrogen cryotherapy is a commonly used technique to treat a wide variety of dermatologic conditions including actinic keratoses, non-melanoma skin cancers, verrucae, and seborrheic keratoses. The risks associated with liquid nitrogen cryotherapy are important to know and discuss with patients prior to treatment. We report a case of cellulitis secondary to liquid nitrogen cryotherapy for actinic keratosis. We sought to review the literature for an estimate of secondary infection rates following cryotherapy treatment. We searched Pubmed using the terms cryotherapy and infection or cellulitis. We then looked at articles classified as clinical trials where cryotherapy was used to treat skin conditions. We then selected clinical trials that listed cellulitis or infection as an adverse event. There were no case reports, case series, or review articles detailing the risk of infection from liquid nitrogen cryotherapy. We found 8 articles classified as clinical trials on Pubmed that did list infection as an adverse event. The risk of infection from these studies varied from approximately 2% to 30%. There was a great degree of heterogeneity in treatment sites, length of treatment, and treatment targets. While it is difficult to determine the true incidence of infection from liquid nitrogen cryotherapy, clinicians should endeavor to inform patients of this potential risk.

Evaluating the Laboratory Risk Indicator to Differentiate Cellulitis from Necrotizing Fasciitis in the Emergency Department

2017-05-01

Full Text Available Introduction: Necrotizing fasciitis (NF is an uncommon but rapidly progressive infection that results in gross morbidity and mortality if not treated in its early stages. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC score is used to distinguish NF from other soft tissue infections such as cellulitis or abscess. This study analyzed the ability of the LRINEC score to accurately rule out NF in patients who were confirmed to have cellulitis, as well as the capability to differentiate cellulitis from NF. Methods: This was a 10-year retrospective chart-review study that included emergency department (ED patients ≥18 years old with a diagnosis of cellulitis or NF. We calculated a LRINEC score ranging from 0–13 for each patient with all pertinent laboratory values. Three categories were developed per the original LRINEC score guidelines denoting NF risk stratification: high risk (LRINEC score ≥8, moderate risk (LRINEC score 6–7, and low risk (LRINEC score ≤5. All cases missing laboratory values were due to the absence of a C-reactive protein (CRP value. Since the score for a negative or positive CRP value for the LRINEC score was 0 or 4 respectively, a LRINEC score of 0 or 1 without a CRP value would have placed the patient in the “low risk” group and a LRINEC score of 8 or greater without CRP value would have placed the patient in the “high risk” group. These patients missing CRP values were added to these respective groups. Results: Among the 948 ED patients with cellulitis, more than one-tenth (10.7%, n=102 of 948 were moderate or high risk for NF based on LRINEC score. Of the 135 ED patients with a diagnosis of NF, 22 patients had valid CRP laboratory values and LRINEC scores were calculated. Among the other 113 patients without CRP values, six patients had a LRINEC score ≥ 8, and 19 patients had a LRINEC score ≤ 1. Thus, a total of 47 patients were further classified based on LRINEC score without a CRP value

Discovery of sessile mode of microbial existence (Biofilm state) focussed much interest, during the recent years, on the study of biofilms in many recurring and chronic infections. However, the exact role of microbial biofilms in chronic rhinosinusitis and orbital cellulitis were not elucidated earlier. The purpose of the present study was to look for the adherent property and biofilm producing ability of the clinical isolates in chronic rhinosinusitis and orbital cellulitis, and to look for the effects of antimicrobial agents on these biofilms by colorimetric assay and ultrastructural analysis. Organisms were isolated and identified from various clinical samples in patients with chronic sinusitis and orbital cellulitis. Antimicrobial sensitivity testing was carried out by the standard protocol. Biofilms were developed; quantified and antimicrobial drug perfusion through the biofilm model was evaluated by the earlier devised procedure. Electronmicroscopic study of the biofilm was performed by the recommended technique. Of the total of 70 clinical samples processed, 48 i.e. 68.5 % grew bacteria and 13 i.e.(18.6 %) fungi. Staphylococcus aureus (20), S epidermidis (16) and Pseudomonas aeruginosa (6) accounted for the majority of the bacterial isolates. Aspergillus flavus (8), however was the commonest amongst the fungi. A total of 40 bacteria and 8 fungi could be tested for biofilm production. Eighteen (45 %) of the 40 bacterial isolates and 4(50 %) out of the 8 A flavus isolates were found to be biofilm producers. In vitro adherence testing revealed that majority i.e. 16 (88.8 %) of the 18 biofilm positive bacteria were adherent to artificial surfaces. Antimicrobial drug perfusion through the biofilm model was poor. Antimicrobial treatment was totally ineffective against strong biofilm producers, whose electron microscopic picture was quite similar to that observed for biofilm producers without any antimicrobial pre-treatment.

Evaluation of IRS-1C LISS-3 satellite data for Norway spruce defoliation assessment

Energy Technology Data Exchange (ETDEWEB)

Falkenstroem, H.

1999-02-01

Satellite based remote sensing supported by air photo and field surveys, provide a means to area covering forest health assessment on a regional scale. Landsat TM data has been extensively used in studies of spruce and fir defoliation in Europe and North America. The temporal coverage of Landsat TM in combination with cloudiness however restrict the availability of data. In this study the LISS-3 sensor onboard the Indian Resource Satellite, IRS-1C, was evaluated for defoliation assessments in Norway spruce (Picea abies) in the central part of Sweden. The near infrared wavelength band proved to be best correlated with mean stand defoliation. After normalisation of satellite data for topographic conditions, the correlation coefficient increased from -0,19 to -0,83. Normalising satellite data for species composition did not improve the results though. The correction coefficients involved in the procedure were originally developed for Landsat TM, and proved to be inadequate for the LISS-3 data set. A thorough examination of the effects of species composition on LISS-3 data is needed to yield better results. The correlation between observed defoliation in the verification stands and predicted (based on the inverse regression function between corrected NIR values and defoliation in reference stands) was 0,70, despite a very limited range of defoliation in the verification set. IRS-1C LISS-3 is fully comparable to Landsat TM for spruce defoliation studies, although the results would probably not be significantly improved 49 refs, 7 figs, 10 tabs

Generation of a new spectral format, the lifetime synchronous spectrum (LiSS), using phase-resolved fluorescence spectroscopy

Shaver, J.M.; McGown, L.B.

1994-01-01

A new fluorescence spectral format is introduced in which fluorescence lifetime is shown as a function of synchronously scanned wavelength to generate a Lifetime Synchronous Spectrum (LiSS). Lifetimes are determined in the frequency domain with the use of Phase-Resolved Fluorescence Spectroscopy (PRFS) to obtain the phase of the fluorescence signal. Theory and construction of the LiSS are presented and experimental results are shown for solutions of single components and simple binary and ternary mixtures. These results show how the lifetime information in the LiSS augments the steady-state intensity information of a standard synchronous spectrum, providing unique information for identification of components and resolution of overlapping spectral peaks. The LiSS technique takes advantage of noise reduction inherent in the extraction of lifetime from PRFS in addition to standard spectral smoothing techniques. The precision of phase determination through PRFS is found to be comparable to that of direct phase measurements at normal fluorescence intensities and superior for low-intensity signals

2016-09-01

Full Text Available Sporotrichosis is a cutaneous or systemic fungal infection caused by Sporothrix schenckii. The infection is characterized by nodular, pustular, or ulcerative lesions. Infection usually occurs after traumatic implantation of the fungus into the skin. We report a case presenting first cellulitis and later on as a non-healing ulcer which was diagnosed by punch biopsy as sporotrichosis and managed successfully with itraconazole. A 56-year-old woman admitted to our department with complaint acute onset of swelling of the right lower-extremity with erythema and warmth. The patient was diagnosed initially as celulitis and started on ampicillin-sulbactam. Diagnosis of sporotrichosis was made with histological examination skin biopsy and the patient was started on itraconazole. One month after commencement of antifungal treatment, the ulcer began to dry up and at 3 months the lesions had healed. This case shows that if a wound do not respond to antibiotics in cases with ulcer, some rare etiological agents should be considered. [Dis Mol Med 2016; 4(3.000: 34-36

2012-05-01

Full Text Available Abstract Background Methicillin-resistant Staphylococcus aureus is a serious cause of morbidity and mortality in hospital environment, but also, lately, in the community. This case report is, to our knowledge, the first detailed description of a community-associated methicillin-resistant S. aureus ST80 orbital cellulitis in a previously healthy neonate. Possible predisposing factors of microbial acquisition and treatment selection are also discussed. Case presentation A 28-day-old Caucasian boy was referred to our hospital with the diagnosis of right orbital cellulitis. His symptoms included right eye proptosis, periocular edema and redness. Empirical therapy of intravenous daptomycin, rifampin and ceftriaxone was initiated. The culture of pus yielded a methicillin-resistant S. aureus isolate and the molecular analysis revealed that it was a Panton-Valentine leukocidine-positive ST80 strain. The combination antimicrobial therapy was continued for 42days and the infection was successfully controlled. Conclusions Clinicians should be aware that young infants, even without any predisposing condition, are susceptible to orbital cellulitis caused by community-associated methicillin-resistant S. aureus. Prompt initiation of the appropriate empirical therapy, according to the local epidemiology, should successfully address the infection, preventing ocular and systemic complications.

2018-03-01

Full Text Available A 58-year-old female presented with 3 weeks history of painful skin lesion on the right cheek. Diagnosis was cellulitis based on the clinical manifestation and laboratory test. However, skin lesion did not improve with antibiotics, and as a consequence, biopsy was performed. Based on histopathological findings and additional information of her previous history of intradermal filler injection, the lesion was diagnosed to be foreign body reaction. Previous reported cases of foreign body reaction induced by hyaluronic acid dermal filler typically manifested as nodular lesions, but cellulitis-like cutaneous manifestation has not been reported. Therefore, we report this interesting case of foreign body reaction after hyaluronic acid dermal filler injection.

Munk, Max M

1927-01-01

The air forces on a systematic series of biplane and triplane cellule models are the subject of this report. The test consist in the determination of the lift, drag, and moment of each individual airfoil in each cellule, mostly with the same wing section. The magnitude of the gap and of the stagger is systematically varied; not, however, the decalage, which is zero throughout the tests. Certain check tests with a second wing section make the tests more complete and conclusions more convincing. The results give evidence that the present army and navy specifications for the relative lifts of biplanes are good. They furnish material for improving such specifications for the relative lifts of triplanes. A larger number of factors can now be prescribed to take care of different cases.

Successful endoscopic management with Mitomycin C application for sinusitis with orbital cellulitis

Directory of Open Access Journals (Sweden)

Anil S Harugop

2013-01-01

Full Text Available Background: Sinusitis with orbital complication is a potentially fatal disease that has been known since the days of Hippocrates. Primary sinus infection is the most common cause of orbital cellulitis. It is an emergency that threatens not only vision but also life from complications such as meningitis, cavernous sinus thrombosis, and brain abscess. Surgical intervention is mandatory whenever antibiotic treatment fails. There are two surgical options for the drainage, an external approach via a Lynch incision and an intranasal endoscopic procedure. Materials and Methods: Five patients with orbital cellulitis secondary to acute on chronic rhinosinusitis were included in the study from the period of 2010 - 2011. All five patients did not respond to medical management and hence underwent endoscopic sinus surgery with treatment of orbital pathology. At the end of the surgical procedure Mitomycin C in a concentration of 0.4mg/ml was applied with a cottonoid for a period of 4 minutes to prevent chance of adhesion formation. Results: In this series 3 females and 2 male patient with orbital cellulitis secondary to acute on chronic rhinosinusitis underwent endoscopic sinus surgery with treatment of orbital pathology. All 5 patients showed subjective and objective improvement within one week of endoscopic management. Conclusion: Though antibiotics have altered the course of sinusitis, its grave complications still persist in our environment. The excellent results and the absence of any major complications of endoscopic sinus surgery and drainage of abscess with application of Mitomycin C can be recommended as the preferred surgical technique.

Objective: To report an aggressive case of extranodal natural killer/T-cell lymphoma (NKTCL) of the ethmoid sinus presenting as orbital cellulitis Method: Case report Results: A 56-year-old male presented with right eye redness, reduced vision, and periorbital swelling for 5 weeks duration associated with a two-month history of blocked nose. The visual acuity of the right eye was 6/18. The eye was proptosed with periorbital oedema and conjunctival chemosis. The pupil was mid-dilated but there was no relative afferent pupillary defect. The fundus was normal. The extraocular movements were restricted in all directions of gaze. Nasal endoscopy revealed pansinusitis that corresponded with CT scan orbit and paranasal sinuses findings. Despite treatment, he showed no clinical improvement. Ethmoidal sinus biopsies performed revealed extranodal NKTCL. Further imaging showed involvement of the right orbital contents and its adnexa with intracranial extension into the right cavernous sinus and meninges over right temporal fossa. The patient underwent chemotherapy. However he succumbed to his illness two months after the diagnosis. Conclusion: Extranodal NKTCL is a great mimicker. This case demonstrated how an acute initial presentation of extranodal NKTCL can present as orbital cellulitis with pansinusitis. PMID:28194321

Cellulitis is a common and costly problem, often diagnosed in the outpatient setting. Many cutaneous conditions may clinically mimic cellulitis, but little research has been done to assess the magnitude of the problem. To determine if obtaining dermatology consultations in the outpatient primary care setting could assist in the diagnosis of pseudocellulitic conditions and reduce the rate of unnecessary antibiotic use. Nonblinded randomized clinical trial of competent adults who were diagnosed as having cellulitis by their primary care physicians (PCPs), conducted at outpatient internal medical primary care offices affiliated with a large academic medical center. Outpatient dermatology consultation. Primary outcomes were final diagnosis, antibiotic use, and need for hospitalization. A total of 29 patients (12 male and 17 female) were enrolled for participation in this trial. Nine patients were randomized to continue with PCP management (control group), and 20 patients were randomized to receive a dermatology consultation (treatment group). Of the 20 patients in the dermatology consultation group, 2 (10%) were diagnosed as having cellulitis. In the control group, all 9 patients were diagnosed as having cellulitis by PCPs, but dermatologist evaluation determined that 6 (67%) of these patients had a psuedocellulitis rather than true infection. All 9 patients (100%) in the control group were treated for cellulitis with antibiotics vs 2 patients (10%) in the treatment group (P Dermatology consultation in the primary care setting improves the diagnostic accuracy of suspected cellulitis and decreases unnecessary antibiotic use in patients with pseudocellulitic conditions.

Full Text Available Bacteria of the genus Salmonella are highly adapted for the growth in both humans and animals and cause a wide spectrum of disease. The growth of Serotypes S. typhi and S. paratyphi is restricted to human hosts, in whom these organisms cause enteric (typhoid fever. The remaining Serotypes (non typhoidal Salmonella or NTS can colonize the gastrointestinal tracts of the broad range of animals, including mammals, reptiles, birds and insects. The usual clinical presentation of non-typhoidal salmonellae (NTS infection is self limited gastroenteritis; however bacteremia and focal extra intestinal infection may occur. However salmonella localization to the skin presenting as cutaneous ulceration is regarded as a rare event. Rates of morbidity and mortality associated with NTS are highest among the elderly, infants, and immunocompromised individuals, including those with hemoglobinopathies, HIV infection, or infections that cause blockade of the reticuloendothelial system. We isolated S.infantis in 50 years old man with left leg cellulitis. The serotype was confirmed at Central Research Institute, Kasauli.

Chun-Ming Chen

2005-07-01

Full Text Available Dens evaginatus is a developmental anomaly that produces a tubercle on the occlusal surface of a tooth. It is found most frequently in the mandibular premolars. The occlusal tubercle easily causes occlusal interferences. Attrition or fracture of the tubercle can lead to pulpitis, pulp necrosis, periapical pathosis, and periapical infection. This case report illustrates the treatment of facial cellulitis arising from dens evaginatus with open apex. Calcium hydroxide was used for the apexification procedure. One year after canal obturation, radiography revealed no apical pathosis and the apical seal was evident.

BACKGROUND Poliomyelitis is a neuromuscular disease which causes muscle atrophy, skeletal deformities, and disabilities. Treatment of hip fractures on polio-affect limbs is unique and difficult, since routine fixation methods like nailing may not be suitable due to abnormal skeletal structures. CASE REPORT We report one femoral neck fracture and one subtrochanteric fracture in polio survivors successfully treated with reverse less invasive stabilization system (LISS) plating technique. Both fractures were on polio-affected limbs with significant skeletal deformities and low bone density. A contralateral femoral LISS plate was applied upside down to the proximal femur as an internal fixator after indirect or direct reduction. Both patients had uneventful bone union and good functional recovery. CONCLUSIONS Reverse LISS plating is a safe and effective technique to treat hip fractures with skeletal deformities caused by poliomyelitis.

Mycobacterium avium-intracellulare cellulitis occurring with septic arthritis after joint injection: a case report

Directory of Open Access Journals (Sweden)

Murdoch David M

2007-02-01

Full Text Available Abstract Background Cellulitis caused by Mycobacterium avium-intracellulare has rarely been described. Mycobacterium avium-intracellulare is a rare cause of septic arthritis after intra-articular injection, though the causative role of injection is difficult to ascertain in such cases. Case presentation A 57-year-old with rheumatoid arthritis treated with prednisone and azathioprine developed bilateral painful degenerative shoulder arthritis. After corticosteroid injections into both acromioclavicular joints, he developed bilateral cellulitis centered over the injection sites. Skin biopsy showed non-caseating granulomas, and culture grew Mycobacterium avium-intracellulare. Joint aspiration also revealed Mycobacterium avium-intracellulare infection. Conclusion Although rare, skin and joint infections caused by Mycobacterium avium-intracellulare should be considered in any immunocompromised host, particularly after intra-articular injection. Stains for acid-fast bacilli may be negative in pathologic samples even in the presence of infection; cultures of tissue specimens should always be obtained.

Conclusion: Intramuscular benzathine penicillin at a 4-week interval may be an effective prophylactic strategy to reduce the incidence of cellulitis. Further studies are necessary to determine the factors associated with failure of prophylaxis as well as optimal individualized dosage and dosing interval of the prophylactic agent.

Skin and soft tissue infections (SSTI) affect millions of people globally, which represents a significant burden on ambulatory care and hospital settings. The role of sulfamethoxazole-trimethoprim (SXT) in SSTI treatment, particularly when group A Streptococcus (GAS) is involved, is controversial. We conducted a systematic review of clinical trials and observational studies that address the utility of SXT for SSTI treatment, caused by either GAS or Staphylococcus aureus , including methicillin-resistant (MRSA). We identified 196 studies, and 15 underwent full text review by 2 reviewers. Observational studies, which mainly focused on SSTI due to S aureus , supported the use of SXT when compared with clindamycin or β-lactams. Of 10 randomized controlled trials, 8 demonstrated the efficacy of SXT for SSTI treatment including conditions involving GAS. These findings support SXT use for treatment of impetigo and purulent cellulitis (without an additional β-lactam agent) and abscess and wound infection. For nonpurulent cellulitis, β-lactams remain the treatment of choice.

To characterise the Emergency Department (ED) prevalence of cellulitis, factors predicting oral antibiotic therapy and the utility of the Clinical Resource Efficiency Support Team (CREST) guideline in predicting patient management in the ED setting, a prospective, cross-sectional study of consecutive adult patients presenting to 3 Irish EDs was performed. The overall prevalence of cellulitis was 12 per 1,000 ED visits. Of 59 patients enrolled, 45.8% were discharged. Predictors of treatment with oral antibiotics were: CREST, Class 1 allocation (odds ratio (OR) 6.81, 95% Cl =1.5-30.1, p=0.012), patient self-referral (OR= 6.2, 95% Cl 1.9- 20.0, p=0.03) and symptom duration longer than 48 hours (OR 1.2, 95% Cl = 1.0-1.5,p=0.049). In conflict with guideline recommendation, 43% of patients in CREST Class 1 received IV therapy. Treatment with oral antibiotics was predicted by CREST Class 1 allocation, self-referral, symptom duration of more than 48 hours and absence of pre-EO antibiotic therapy.

The records of 15 dogs diagnosed as having juvenile cellulitis (juvenile pyoderma, puppy strangles) were evaluated for clinical, laboratory, and therapeutic results. Mandibular lymphadenopathy was observed in 14 dogs, and was not associated with skin lesions in 5 dogs. Edema, pustules, papules, or crusts were noticed periorally, periocularly, on the chin or muzzle, or in the ears of those dogs with skin lesions. Eight dogs were lethargic; fever and anorexia were inconsistent findings. Four dogs had signs of pain on manipulation of their joints. Complete blood counts revealed leukocytosis with neutrophilia in 4 dogs, and normocytic, normochromic anemia in 6 dogs. Three dogs had suppurative lymphadenitis with many neutrophils. Cytology of the aspirate of pustules or abscesses in 6 dogs revealed many neutrophils without bacteria. Coagulase-positive Staphylococcus spp were isolated from draining lesions in 2 dogs. Intact abscesses and lymph nodes were negative for bacterial growth in 4 dogs. Three of these dogs were being administered antibiotics at the time of bacterial culturing. Cytology of the aspirates of joints in 3 of the 4 dogs with joint pain revealed suppurative arthritis with no bacteria, and the aspirates were negative for bacterial growth on culturing, although all 3 dogs were being administered antibiotics at the time of culturing. Of 12 dogs initially treated with antibiotics, only 4 (33%) responded favorably; the other 8 dogs were then given antibiotics and corticosteroids. Three dogs were initially given antibiotics and corticosteroids. All dogs treated concurrently with antibiotics and corticosteroids responded favorably. One of these dogs had a relapse after treatment was discontinued. The concurrent arthritis in 4 of the dogs resolved with treatment of the juvenile cellulitis and did not redevelop once the medication was discontinued. Concurrent treatment with antibiotics (cephalosporins) and prednisone (2.2 mg/kg of body weight/day) was the most

Hypothesis of Lithocoding: Origin of the Genetic Code as a "Double Jigsaw Puzzle" of Nucleobase-Containing Molecules and Amino Acids Assembled by Sequential Filling of Apatite Mineral Cellules.

The hypothesis of direct coding, assuming the direct contact of pairs of coding molecules with amino acid side chains in hollow unit cells (cellules) of a regular crystal-structure mineral is proposed. The coding nucleobase-containing molecules in each cellule (named "lithocodon") partially shield each other; the remaining free space determines the stereochemical character of the filling side chain. Apatite-group minerals are considered as the most preferable for this type of coding (named "lithocoding"). A scheme of the cellule with certain stereometric parameters, providing for the isomeric selection of contacting molecules is proposed. We modelled the filling of cellules with molecules involved in direct coding, with the possibility of coding by their single combination for a group of stereochemically similar amino acids. The regular ordered arrangement of cellules enables the polymerization of amino acids and nucleobase-containing molecules in the same direction (named "lithotranslation") preventing the shift of coding. A table of the presumed "LithoCode" (possible and optimal lithocodon assignments for abiogenically synthesized α-amino acids involved in lithocoding and lithotranslation) is proposed. The magmatic nature of the mineral, abiogenic synthesis of organic molecules and polymerization events are considered within the framework of the proposed "volcanic scenario".

As many doctors know little about gas-forming synergistic necrotizing cellulitis, we retrospectively explored it in our study. Totally, 30 patients diagnosed with gas-forming synergistic necrotizing cellulitis between November 2006 and September 2015 were included. They were divided into two groups: open drainage group (19 patients) and aggressive debridement group (11 patients). Retrospectively analyzed data comprised demographic characteristics, APACHE II scores, pathogen culture results, bleeding amount during the operation, white blood cell count, length of hospital stay and recovery. The mortality rate was 26% in the open drainage group and 73% in the aggressive debridement group (p=0.023). There was no statistical difference in the APACHE II score before treatment between the open drainageand aggressive debridement groups (16.6±4.5 vs 18.1±7.5, p=0.511). The APACHE II score was significantly higher after treatment in the aggressive debridement group (14.2±5.8 score vs 20.1±9.1, p=0.038). There were no statistical differences in the white blood count cell before and after treatment (13.49 × 109±5.05×109 cells/L vs 17.46×109±6.94×109 cells/L, p=0.082; 10.37×109±3.54×109 cells/L vs 15.47×109 ±7.51×109 cells/L, p=0.055; respectively). The bleeding amount during the operation was significantly more in the aggressive debridement group (315±112 ml vs 105±45 ml, pgas-forming synergistic necrotizing cellulitis, performing open drainage as early as possible isthe most important procedure after admission.

Eosinophilic cellulitis (Wells’ syndrome) is an uncommon condition of unknown etiology. Wells’ syndrome is usually seen in adulthood but very rare in childhood. Although pathogenesis of the disease is not very clear, it is a hypersensitivity reaction developing against a variety of exogenous and endogenous antigenic stimuli. Paraphenylenediamine is a strong allergen frequently used as a temporary henna tattoo, which makes the color darker. Here, a 9-year-old male patient with Wells’ syndrome is presented, which developed following a temporary henna tattoo and shown by the patch test sensitivity to paraphenylenediamine. PMID:25395929

Modelling of the Liquid Injection Shutdown System (LISS) in the ACR-1000 reactor core must account for the major phenomena that occur following its activation, namely the moderator hydraulics and core neutronics. The former requires modelling of the poison volumes, their time of entry into the reactor, and their propagation into the moderator after emission from the nozzle. The latter requires the reactivity worth of varying volumes and geometries of poisoned moderator fluid in order to simulate the reactivity effect of the injected poison. The time-dependent poison map is generated from hydraulic calculations, and then the neutronics data for standard geometries and concentrations is constructed using DRAGON. (author)

The benefits of treating children at home or in an ambulatory setting have been well documented. We aimed to describe the characteristics and evaluate the outcomes of children with moderate/severe cellulitis treated at home with intravenous (IV) ceftriaxone via direct referral from the Emergency Department to a hospital-in-the-home (HITH) program. Patients aged 3 months to 18 years with moderate/severe cellulitis referred from a tertiary pediatric Emergency Department to HITH from September 2012 to January 2014 were prospectively identified. Data collection included demographics, clinical features, microbiological characteristics and outcomes. To ensure home treatment did not result in inferior outcomes, these patients were retrospectively compared with patients who were hospitalized for IV flucloxacillin, the standard-of-care over the same period. The primary outcome was home treatment failure necessitating hospital admission. Secondary outcomes included antibiotic changes, complications, length of stay and cost. Forty-one (28%) patients were treated on HITH and 103 (72%) were hospitalized. Compared with hospitalized patients, HITH patients were older (P antibiotic changes was similar in both groups (5% vs. 7%, P = 0.67), as was IV antibiotic duration (2.3 vs. 2.5 days, P = 0.23). Older children with moderate/severe limb cellulitis without systemic symptoms can be treated at home. To ascertain if this practice can be applied more widely, a comparative prospective, ideally randomized, study is needed.

Extranodal natural killer (NK)/T-cell lymphoma is a very rare and aggressive disease characterized histopathologically by an Epstein-Barr virus (EBV)-positive atypical lymphoid cytotoxic infiltrate, extensive vascular destruction, and prominent tissue necrosis. It commonly shows cutaneous lesions that primarily or secondarily mimic cellulitis at the primary site. We report on a very rare case of extranodal NK/T-cell lymphoma, nasal type of skin/soft tissue, in a 64-year-old man, and describe the radiological findings. The condition was misdiagnosed as cellulitis of the left arm based on initial noninvasive clinical and radiologic work-up

Full Text Available We illustrate a case involving a 51-year-old man who presented to a tertiary hospital with sepsis secondary to an abscess of the nasal vestibule and pustular eruptions of the nasal mucosa. Associated cellulitis extended across the face to the eye, and mucosal thickening of the sinuses was seen on computed tomography. The patient underwent incision and drainage and endoscopic sinus surgery. Blood cultures and swabs were positive for a gram-negative bacillus, Burkholderia pseudomallei. He had multiple risk factors including travel to an endemic area. The patient received extended antibiotic therapy in keeping with published national guidelines. Melioidosis is caused by Burkholderia pseudomallei, found in the soil in Northern Australia and Asia. It is transmitted via cutaneous or inhaled routes, leading to pneumonia, skin or soft tissue abscesses, and genitourinary infections. Risk factors include diabetes, chronic lung disease, and alcohol abuse. It can exist as a latent, active, or reactivated infection. A high mortality rate has been identified in patients with sepsis. Melioidosis is endemic in tropical Northern Australia and northeastern Thailand where it is the most common cause of severe community-acquired sepsis. There is one other report of melioidosis in the literature involving orbital cellulitis and sinusitis.

Stenotrophomas maltophilia is an opportunistic Gram-negative bacillus and an important cause of nosocomial infections, particularly in immunosuppressed individuals. Although infections with this organism are most often in the form of pneumonia, bacteremia and endocarditis, awareness of the impact of S. maltophilia skin infections has been increasing. Here we describe a case of S. maltophilia cellulitis in a 65-year-old man with severe neutropenia and purpuric skin lesions to highlight the critical histopathological findings and correlate them with the clinical manifestations of the skin infection with this organism. Because identification of S. maltophilia can be challenging and infections are difficult to manage, this case illustrates essential considerations regarding the multifaceted histopathological, dermatological, clinical and microbiological aspects of the diagnosis and treatment of S. maltophilia cellulitis in a severely immunocompromised patient. Cognizance of the increasing incidence of nosocomial infections with uncommon microorganisms such as S. maltophilia is necessary when presented with atypical cutaneous manifestations, particularly in immunocompromised patients. © 2016 John Wiley & Sons A/S.

Facing the Danger Zone: The Use of Ultrasound to Distinguish Cellulitis from Abscess in Facial Infections

Directory of Open Access Journals (Sweden)

Dywanda L. Lewis

2014-01-01

Full Text Available Physical exam alone is often insufficient to determine whether or not cellulitis is accompanied by an abscess. Bedside ultrasound can be a valuable tool in ruling out suspected abscess by allowing direct visualization of a fluid collection. The proximity of the infection to adjacent structures can also be determined, thus aiding clinical decision making. Patients with cellulitis near the eye and nose are of particular concern due to the adjacent facial structures and the anatomy of the venous drainage. Accurately determining the presence or absence of an associated abscess in these patients is a crucial step in treatment planning. The purpose of this report is to (1 emphasize the benefits of bedside ultrasound when used in conjunction with the physical exam to rule out abscess; (2 demonstrate the utility of bedside ultrasound in planning a treatment strategy for soft tissue infection; (3 depict an instance where ultrasound detected an abscess when computed tomography (CT scan did not.

Lower limb (LL) cellulitis-related hospitalisations are prevalent in type 2 diabetes subjects. We assess its costs and factors associated with length of stay and readmissions. A retrospective case-control study at an urban hospital servicing a multi-ethnic population in New Zealand, where 7% of the adult population is estimated to have diabetes. Admissions with LL cellulitis in 2008-2013 were identified using coding records. Subsequent hospitalisations after 1 month with the same diagnosis were classified as readmissions. Glycaemic control was assessed by HbA1c measured within 6 months of the index admission. There were 4600 admissions with LL cellulitis in 3636 patients, including 719 patients (20%) with type 2 diabetes. Hospital stay was longer for type 2 diabetes patients (median 5.3 vs 3.0 days, P < 0.001), independent of age, ethnicity and HbA1c. Accompanying LL ulceration was more frequent in type 2 diabetes patients (50% vs 17%, P < 0.001); however, admissions remained longer for type 2 diabetes patients without ulceration (median 3.4 vs 2.8 days, P < 0.001). Readmission rates were also higher in type 2 diabetes patients compared to non-diabetes patients (HR 1.7, P < 0.001), even in the absence of ulceration (HR 2.2, P < 0.001). Age, HbA1c and ethnicity did not distinguish those prone to readmissions in the type 2 diabetes cohort. Type 2 diabetes patients accounted for a fifth of all admissions and one third of the estimated costs. A high proportion of patients with type 2 diabetes was admitted with LL cellulitis. They had significantly longer admissions and higher readmission rates. Age, HbA1c and ethnicity did not predict length of stay or recurrence. © 2016 Royal Australasian College of Physicians.

Décrite pour la première fois en 1926 par Abrikossoff, les tumeurs à cellules granuleuses (TCG) sont bénignes et uniques dans la grande majorité des cas. Les principales localisations sont la cavité orale, puis les tissus sous-cutanés de la tête et du cou et les seins. La pathogenèse a été longtemps débattue, après avoir proposé initialement une origine musculaire striée les études récentes sont en faveur d'une origine neurogène schwannienne confirmées par une étude immunohistochimique. Le traitement de la tumeur à cellules granuleuses est un traitement chirurgical, il permet un diagnostic de certitude par l'examen anatomo-pathologique de la pièce d'exérèse qui doit rechercher les limites d'exérèse et la présence de critères de malignité. Leur évolution est souvent favorable si la résection chirurgicale est complète. Nous rapportons ici le cas d'une tumeur d'Abrikossoff à localisation juxta axillaire et nous profitons de faire une revue de la littérature afin de mettre le point sur cette entité rare.

2014-11-01

Continuous and automated co-registration and geo-tagging of images from multiple bands of Liss-4 camera is one of the interesting challenges of Resourcesat-2 data processing. Three arrays of the Liss-4 camera are physically separated in the focal plane in alongtrack direction. Thus, same line on the ground will be imaged by extreme bands with a time interval of as much as 2.1 seconds. During this time, the satellite would have covered a distance of about 14 km on the ground and the earth would have rotated through an angle of 30". A yaw steering is done to compensate the earth rotation effects, thus ensuring a first level registration between the bands. But this will not do a perfect co-registration because of the attitude fluctuations, satellite movement, terrain topography, PSM steering and small variations in the angular placement of the CCD lines (from the pre-launch values) in the focal plane. This paper describes an algorithm based on the viewing geometry of the satellite to do an automatic band to band registration of Liss-4 MX image of Resourcesat-2 in Level 1A. The algorithm is using the principles of photogrammetric collinearity equations. The model employs an orbit trajectory and attitude fitting with polynomials. Then, a direct geo-referencing with a global DEM with which every pixel in the middle band is mapped to a particular position on the surface of the earth with the given attitude. Attitude is estimated by interpolating measurement data obtained from star sensors and gyros, which are sampled at low frequency. When the sampling rate of attitude information is low compared to the frequency of jitter or micro-vibration, images processed by geometric correction suffer from distortion. Therefore, a set of conjugate points are identified between the bands to perform a relative attitude error estimation and correction which will ensure the internal accuracy and co-registration of bands.

Primary cutaneous nocardiosis is an infrequent infection among children, generally affecting immunocompromised hosts. It is caused by Gram positive bacteria, partially alcohol and acid resistant which are saprophytes of the soil, water and organic matter. In most cases the causal agent enters through inhalation, and hematogenous dissemination may occur mainly among the immune compromised patients. Direct cutaneous inoculation is less frequent, especially among children. We report an 8-year old female who lives in an urban house with a small garden, who presented with an ulcer on her right shin accompanied by surrounding cellulitis, pain, swelling and fever. The patient's medical history was unremarkable, with no exposure to animals or travelling, except for rafting on the Jordan River the previous week. Culture from the ulcer grew Nocardia brasiliensis, and she recovered after 8 weeks of therapy with trimethoprim-sulphamethoxazole.

Comparison of satellite imagery from LISS-III/Resourcesat-1 and TM/Landsat 5 to estimate stand-level timber volume

Full Text Available After Landsat 5 activities were discontinued, sensors on board ResourceSat-1 satellite have been pointed as an option for Landsat series. The aim of this study is to estimate timber volume from a slash pine (Pinus elliottii Engelm. stand using images from both LISS-III/ResourceSat-1 and TM/Landsat 5 sensors, cross comparing their performances. Reflectance values from the four spectral bands considered equivalent for both sensors were compared regarding sensitivity to changes in timber volume. Trends were similar, with direct relationship in the near-infrared bands and inverse relationships in the visible and mid-infrared bands. Significant differences were only found in the equivalent band of green. Multiple linear regressions were used to select spectral bands that would better explain variations in timber volume. The best fit equations for each sensor were inverted to generate maps of timber volume, estimates which were compared at pixel and stand level. None of the scales showed significant differences between estimates generated from the two sensors. We concluded that LISS-III and TM have generally very similar performance for monitoring timber volume, and LISS-III could therefore be potentially used as a complement or substitute to Landsat series.

Full Text Available Chemical cellulitis is the reaction of the integuments in response to the administration of toxic substances, leading to an acute inflammatory reaction that develops into an abscess or necrosis. This disease is not frequently treated in the Department of Orthopedics and Traumatology of the Joaquin Albarrán Clinical-Surgical Hospital. We present the case of a patient who attended our institution because of increased volume in both upper limbs at the biceps and triceps areas, and marked skin necrosis accompanied by lesions of axillary adenopathy, one as an abscess. Antibiotics were prescribed prior to the completion of cultures, antibiogram and dressing under anesthesia, at present the lesions are in the healing phase.

Lemierre syndrome is characterized by a septic thrombophlebitis of the internal jugular vein (IJV) following an oropharyngeal infection. We report a case of Lemierre syndrome that occurred in a context of angina and necrotizing cellulitis of the neck in a 45-year-old patient. The Doppler ultrasound exam of the neck vessels and a neck CT showed an IJV thrombophlebitis. No germ could be isolated in the samples (blood culture, pus). The treatment associated antibiotics, heparin and surgical debridement of the necrotic tissues with extraction of the thrombus after ligation and section of the IJV. The postoperative course was uneventful. Lemierre syndrome is a rare but serious disease. Its low incidence makes him a forgotten disease. It should be systematically suspected in any oropharyngeal infection with the presence of a large painful swelling of the neck. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Emergency department visits for skin infections in the United States have increased with the emergence of methicillin-resistant Staphylococcus aureus (MRSA). For cellulitis without purulent drainage, β-hemolytic streptococci are presumed to be the predominant pathogens. It is unknown if antimicrobial regimens possessing in vitro MRSA activity provide improved outcomes compared with treatments lacking MRSA activity. To determine whether cephalexin plus trimethoprim-sulfamethoxazole yields a higher clinical cure rate of uncomplicated cellulitis than cephalexin alone. Multicenter, double-blind, randomized superiority trial in 5 US emergency departments among outpatients older than 12 years with cellulitis and no wound, purulent drainage, or abscess enrolled from April 2009 through June 2012. All participants had soft tissue ultrasound performed at the time of enrollment to exclude abscess. Final follow-up was August 2012. Cephalexin, 500 mg 4 times daily, plus trimethoprim-sulfamethoxazole, 320 mg/1600 mg twice daily, for 7 days (n = 248 participants) or cephalexin plus placebo for 7 days (n = 248 participants). The primary outcome determined a priori in the per-protocol group was clinical cure, defined as absence of these clinical failure criteria at follow-up visits: fever; increase in erythema (>25%), swelling, or tenderness (days 3-4); no decrease in erythema, swelling, or tenderness (days 8-10); and more than minimal erythema, swelling, or tenderness (days 14-21). A clinically significant difference was defined as greater than 10%. Among 500 randomized participants, 496 (99%) were included in the modified intention-to-treat analysis and 411 (82.2%) in the per-protocol analysis (median age, 40 years [range, 15-78 years]; 58.4% male; 10.9% had diabetes). Median length and width of erythema were 13.0 cm and 10.0 cm. In the per-protocol population, clinical cure occurred in 182 (83.5%) of 218 participants in the cephalexin plus trimethoprim

Cutaneous Paecilomyces lilacinus infection mimicking cellulitis in an immunocompetent patient: Report of a case and review of the literature

Full Text Available Paecilomyces lilacinus, a ubiquitous saprophytic mold found in the environment, is an emerging pathogen that causes localized to severe systemic diseases, especially in immunocompromised patients. Thus far, there are only eight reports on immunocompetent patients with cutaneous P. lilacinus in the English literature. We herein present the case of an 87-year-old immunocompetent Taiwanese man who presented with a progressive, tender, erythematous plaque mimicking cellulitis on the ventral surface of the right forearm for 2 weeks. The patient was initially diagnosed as a case of cellulitis; however, due to unresponsiveness to the treatment for 1 week, we decided to perform skin biopsy and tissue culture. Results of histopathologic analysis, tissue culture, and polymerase chain reaction assay indicated cutaneous P. lilacinus infection. Consequently, systemic antifungal treatment with oral itraconazole (200 mg/d was initiated and the skin lesion resolved after a 4-week treatment.

1. This study was conducted to verify the impact of different kinds of material and the number of times of litter reuse on the incidence of chicken pathologies. Approximately 4·5 million broilers from conventional Brazilian farms were evaluated in the abattoir for cellulitis, arthritis and contact foot-pad dermatitis. 2. Four different kinds of litter material, Brachiaria grass, corncob, sawdust and rice shell, were used. Brachiaria grass litter showed the highest incidence of contact foot-pad dermatitis. Corncob litter also showed some negative effects on foot quality. Broilers raised on rice shell litter showed good results in terms of the incidence of contact foot-pad dermatitis. The best results were obtained with sawdust litter, because the incidence of cellulitis and arthritis were the lowest and the incidence of contact foot-pad dermatitis was also very low.

Bamber, M J

1935-01-01

General methods of theoretical analysis of airplane spinning characteristics have been available for some time. Some of these methods of analysis might be used by designers to predict the spinning characteristics of proposed airplane designs if the necessary aerodynamic data were known. The present investigation, to determine the spinning characteristics of wings, is planned to include variations in airfoil sections, plan forms, and tip shapes of monoplane wings and variations in stagger, gap, and decalage for biplane cellules. The first series of tests, made on a rectangular Clark Y monoplane wing, are reported in reference 1. That report also gives an analysis of the data for predicting the probable effects of various important parameters on the spin for normal airplanes using such a wing. The present report is the second of the series. It gives the aerodynamic characteristics of a rectangular Clark Y biplane cellule in spinning attitudes and includes a discussion of the data, using the method of analysis given in reference 1.

As hospital crowding has increased, more patients have ended up boarding in the emergency department (ED) awaiting their inpatient beds. To the best of our knowledge, no study has compared the quality of care of boarded and nonboarded patients. This study sought to examine whether being a boarded patient and boarding longer were associated with more delays, medication errors, and adverse events among ED patients admitted with chest pain, pneumonia, or cellulitis. This study was a retrospective cohort design in which data collection was accomplished via medical record review from two urban teaching hospitals. Patients admitted with chest pain, pneumonia, or cellulitis between August 2004 and January 2005 were eligible for inclusion. Our outcomes measures were: 1) delays in administration of home medications, cardiac enzyme tests, partial thromboplastin time (PTT), and antibiotics; 2) medication errors; and 3) adverse events or near misses. Primary independent variables were boarded status, boarding time, and boarded time interval. Multiple logistic regression models controlling for patient, ED, and hospital characteristics were used. A total of 1,431 patient charts were included: 811 with chest pain, 387 with pneumonia, and 233 with cellulitis. Boarding time was associated with an increased odds of home medication delays (adjusted odds ratio [AOR] = 1.07, 95% confidence interval [CI] = 1.05 to 1.10), as were boarded time intervals of 12, 18, and 24 hours. Boarding time also was associated with lower odds of having a late cardiac enzyme test (AOR = 0.93, 95% CI = 0.88 to 0.97). Boarding was associated with home medication delays, but fewer cardiac enzyme test delays. Boarding was not associated with delayed PTT checks, antibiotic administration, medication errors, or adverse events/near misses. These findings likely reflect the inherent resources of the ED and the inpatient units. © 2011 by the Society for Academic Emergency Medicine.

LISS: Planning for spin physics with multi-GeV nucleon beams at IUCF

1995-01-01

The technology developed in recent years to facilitate experiments with stored, cooled polarized beams bombarding internal targets (including polarized gaseous targets) has natural and novel applications at multi-GeV energies. At IUCF we are preparing a proposal for a Light-Ion Spin Synchrotron (LISS) that would adapt this technology to the exploration of nucleon spin physics in the non-perturbative QCD regime from 1 endash 20 GeV. I will describe the research goals of such a facility, with emphasis on a few contemplated experiments, chosen to illustrate both the range of physics issues to be addressed and the considerable advantages offered by storage ring techniques. copyright 1995 American Institute of Physics

Full Text Available A importância das imagens de sensoriamento remoto para o monitoramento da cobertura vegetal é algo inegável. Por mais de três décadas a série Landsat tem fornecido imagens da terra, porém a partir de novembro de 2011 o satélite interrompeu a disponibilização de suas imagens para o monitoramento ambiental. Uma das alternativas de imagens ao Landsat têm sido as imagens do sensor LISS III a bordo do satélite indiano Resourcesat 1. O presente trabalho tem como área de estudo o município de Janaúba, por estar em uma área de transição de dois biomas, e o mesmo tem por objetivo comparar os dois sensores, o sensor TM que se encontra a bordo do satélite Landsat 5 e o sensor LISS III a bordo do satélite Resourcesat 1. Para esse estudo comparativo as imagens foram adquiridas do site do Instituto Nacional de Pesquisas Espaciais (INPE e seus valores de níveis digitais (ND foram convertidos em reflectância com correção atmosférica utilizando o método de correção DOS. Amostras de pixels das imagens índice foram coletadas para o estudo de correlação e ajuste de uma equação linear por meio da técnica de regressão. Utilizando a equação ajustada foram gerados dois mapas temáticos de ambos os sensores, sendo os mesmos comparados pelo teste estatístico Kappa. Os resultados mostraram uma forte correlação entre os valores de NDVI (0,81, sendo possível o ajuste de uma equação linear que expresse a forma dessa relação. O sensor TM, superestimou os valores de NDVI em relação ao sensor LISS III (Inclinação de 1,1035. O valor de Kappa para os mapas temáticos obtidos foi de 0,5894 e o índice de acerto foi de 98,81%, o que mostra uma boa similaridade entre eles. O sensor LISS III pode ser perfeitamente utilizado como alternativa ao Landsat 5.

Flucloxacillin either alone or combined with penicillin V is still the first-line antibiotic drug of choice for the treatment of cellulitis in emergency departments (EDs) in Ireland. The rationale for this antibiotic regimen is their anti-staphylococcal and anti-streptococcal activity. To determine the clinical efficacy, tolerability and safety of oral flucloxacillin alone (monotherapy) compared with a combination of flucloxacillin with penicillin V (dual therapy) in the ED-directed outpatient treatment of cellulitis. We searched the following electronic databases: MEDLINE (1950 to August 2011), EMBASE (1980 to August 2011), Cochrane Central Register of Controlled Clinical Trials (CENTRAL) (The Cochrane Library 2011, Issue), OpenGrey, Current Controlled Trials metaRegister of Clinical Trials (August 2011) and reference lists and websites of potential trials. We performed cross-referencing from the reference lists of major articles on the subject. We imposed no language restriction. Despite a comprehensive literature search to identify relevant studies, no randomized-controlled trials that fulfilled the inclusion criteria were found. Despite its common use, there are no published randomized-controlled trials comparing flucloxacillin monotherapy with a combination of flucloxacillin and penicillin V in the ED management of cellulitis. We discuss existing European and North American prescribing rationale and current guidelines.

2006-11-01

Full Text Available A universal dimensionless scaling group and its critical value at the onset of instability for a miscible displacement in a Hele-Shaw cell is derived. The derivation is based on a variational technique and it is capable of considering, for the first time, the effect of the length of a Hele-Shaw cell on the criterion for the onset of instability. The theory is verified by comparing it with forty-four Hele-Shaw cell experiments. On calcule un groupe universel sans dimension de mise à l'échelle et sa valeur critique au départ de l'instabilité dans un déplacement miscible dans une cellule Hele-Shaw. Ce calcul est basé sur une technique variationnelle et permet, pour la première fois, de prendre en compte l'effet de la longueur d'une cellule Hele-Shaw sur le critère d'apparition d'instabilité. La théorie est vérifiée en la comparant avec des expériences réalisées avec quarante-quatre cellules Hele-Shaw.

Cemento-ossifying Fibroma Of Paranasal Sinus Presenting Acutely As Orbital Cellulitis.

Science.gov (United States)

Khanna, Maneesh; Buddhavarapu, Shanker Rao; Hussain, Sheik Akbar; Amir, Emran

2009-01-01

Fibro-osseous lesions of the face and paranasal sinuses are relatively uncommon. These lesions have overlapping clinical, radiologic and pathologic features causing difficulty in diagnosis. Neoplastic fibro-osseous paranasal sinus lesions can be benign or malignant. The benign fibro-osseous lesions described are: ossifying fibroma (and its histologic variants) and fibrous dysplasia. The variants of ossifying fibroma differ in the nature of calcified material (i.e. cementum versus bone), in the location of the lesion (oral versus paranasal sinus or orbital), other morphologic variations (presence of psammomatoid concretions) and biologic behavior (aggressive versus stable). Presence of cementum or bone classifies the lesion as cementifying fibroma or ossifying fibroma respectively while lesions with mixture of both cementum and bone are called cemento-ossifying fibroma. We describe a case of a young adult male with cemento-ossifying fibroma of paranasal sinus presenting acutely as left orbital cellulitis with proptosis.

The acute orbit: Differentiation of orbital cellulitis from subperiosteal abscess by computerized tomography

International Nuclear Information System (INIS)

Handler, L.C.; Davey, I.C.; Hill, J.C.; Lauryssen, C.

1991-01-01

A series of 65 patients suffering from acute inflammatory disease of the orbit was studied by CT. Ethmoiditis was the cause in the vast majority; trauma and dental extraction played a lesser role in causation. Orbital cellulitis was diagnosed in 17 and subperiosteal abscess in the remaining 48. It was not possible to differentiate 33 pus-containing abscesses from the six with inflammatory masses (phlegmons). The satisfactory response to aggressive medical treatment in those patients with inflammatory masses that were not drained justifies a more conservative approach; surgical drainage being reserved for those with a deterioration in proptosis, ocular movements or vision. Six abscesses arose de novo, of which some were in the orbital fat rather than the subperiosteal space. (orig.)

Review of a case of paraosseous extramedullary hematopoiesis (EMH) affecting the maxillary sinuses and retro-orbital spaces imitating bilateral orbital cellulitis. Maxillofacial EMH causes diagnostic/therapeutic challenges. This case report describes a 4-year-old African American male with sickle cell disease (HbSS) who presented with bilateral orbitofacial swelling. Diagnosis was made with imaging and confirmed with tissue sampling. Partial exchange transfusion was utilized to stop the progression of maxillofacial EMH and to treat the patient's chronic anemia. Follow-up MRI showed regression of orbital and retro-orbital involvement. Early treatment with conservative modalities and close observation may prevent need for more invasive treatments.

Full Text Available There are reported cases of diphencyprone used in treating cutaneous metastases of melanoma. Here, we report a patient with previous primary melanoma on his left back treated with surgical excision and lymphadenectomy, followed by radiotherapy for the recurrent tumor on the primary site. Despite radiotherapy and treatment with dabrafenib and trametinib, in-transit metastases have developed and topical diphencyprone was applied to these metastases. Six weeks later, the patient developed fever and a spreading erythematous tender indurated plaque covering the left side of the body including axillae, back, and flank, clinically suggestive of cellulitis. Systemic antibiotic therapy did not improve the condition and a biopsy showed sparse lymphocytic infiltrate. With the diagnosis of possible acute lymphedema, a CT scan was requested that showed significant axillary lymph node metastasis. The fever was considered secondary to dabrafenib and trametinib therapy. This case highlights that, in patients with lymphadenectomy, atypical forms of lymphedema on the body may appear. Truncal lymphedema is an infrequent event.

M2 macrophages play a critical role in the recruitment of T helper 2 (Th2) regulatory T cells (Treg). To study the role of M2 macrophages and Treg cells in eosinophilic celulitis. We employed immunohistochemical staining for CD163( )and CD206 (macrophages) as well as FoxP3 (Treg), in lesional skin of four cases of eosinophilic cellulitis. CD163(+) CD206(+) M2 macrophages, which were previously reported to produce CCL17 to induce Th2 cells and Treg cells, were predominantly infiltrating the subcutaneous tissues and interstitial area of the dermis. M2 macrophages derived from PBMC showed significantly increased expression of CCL11, CCL17, CCL24 and CCL26 mRNA and production of CCL17 and CCL24, when stimulated by IL-4 or IL- 13. In addition, CCL17-producing cells and CCL24-producing cells were prominent in the lesional skin of EC. Our study sheds light on one of the possible immunological mechanisms of eosinophilic cellulitis.

Ultrahigh-rate supercapacitors with large capacitance based on edge oriented graphene coated carbonized cellulous paper as flexible freestanding electrodes

Large-capacitance and ultrahigh-rate electrochemical supercapacitors (UECs) with frequency response up to kilohertz (kHz) range are reported using light, thin, and flexible freestanding electrodes. The electrode is formed by perpendicularly edge oriented multilayer graphene/thin-graphite (EOG) sheets grown radially around individual fibers in carbonized cellulous paper (CCP), with cellulous carbonization and EOG deposition implemented in one step. The resulted ∼10 μm thick EOG/CCP electrode is light and flexible. The oriented porous structure of EOG with large surface area, in conjunction with high conductivity of the electrode, ensures ultrahigh-rate performance of the fabricated cells, with large areal capacitance of 0.59 mF cm-2 and 0.53 mF cm-2 and large phase angle of -83° and -80° at 120 Hz and 1 kHz, respectively. Particularly, the hierarchical EOG/CCP sheet structure allows multiple sheets stacked together for thick electrodes with almost linearly increased areal capacitance while maintaining the volumetric capacitance nearly no degradation, a critical merit for developing practical faraday-scale UECs. 3-layers of EOG/CCP electrode achieved an areal capacitance of 1.5 mF cm-2 and 1.4 mF cm-2 at 120 Hz and 1 kHz, respectively. This demonstration moves a step closer to the goal of bridging the frequency/capacitance gap between supercapacitors and electrolytic capacitors.

Technologies and devices for cosmetic procedures are developing with each passing day. However, increased and unauthorized use of such emerging technologies may also lead to increases in unexpected results and complications as well. Here, we report a case of facial cellulitis after a "beauty parlor" session of skin cleaning with jet stream peeling device in 19-year old female patient for the first time. Complications due to improper and unauthorized use of jet stream peeling devices may also cause doubts about the safety and impair the reputation of the technology as well. In order to avoid irreversible complications, local authorities should follow the technology and update the regulations where the dermatologists should take an active role.

Serratia marcescens is a Gram-negative bacillus belonging to the Enterobacteriaceae family. Cutaneous infection with Serratia is rare, and usually occurs in immunocompromised individuals. Primary cutaneous infections are uncommon, but they are typically severe and are associated with significant morbidity and mortality. The pathogenetic factors leading to S. marcescens infection are not fully understood, but contributing virulence factors include proteases, secreted exotoxins, and the formation of biofilm. We report a case of cellulitis occurring in a splenectomized patient, which led to multiple wound debridements and a transmetatarsal amputation. This dramatic case led us to review the published literature on soft tissue infections caused by S. marcescens. © The Author(s) 2016.

A conventional metallographic apparatus has been adapted for work in a protected cell. The small size of the apparatus and the placing of this apparatus simply on a working bench which can easily be dismantled make it possible on the one hand to repair the apparatus easily in the event of a breakdown, and on the other hand to decontaminate it fairly easily without the presence of a technician in the cell. (authors) [French] Une installation de metallographie classique a ete adaptee au travail en cellule blindee.

2014-01-01

Full Text Available Technologies and devices for cosmetic procedures are developing with each passing day. However, increased and unauthorized use of such emerging technologies may also lead to increases in unexpected results and complications as well. Here, we report a case of facial cellulitis after a “beauty parlor” session of skin cleaning with jet stream peeling device in 19-year old female patient for the first time. Complications due to improper and unauthorized use of jet stream peeling devices may also cause doubts about the safety and impair the reputation of the technology as well. In order to avoid irreversible complications, local authorities should follow the technology and update the regulations where the dermatologists should take an active role.

Acute bacterial cellulitis of the leg (erysipelas) is a common problem involving considerable morbidity in dermatology practice in Africa. Previous studies conducted in Europe and North Africa have highlighted lymphoedema and toe-web intertrigo as independent factors associated with leg erysipelas. The aim of this case-control study was to identify risk factors associated with leg erysipelas in sub-Saharan Africa, within a different socio-economic and culture context. We conducted a prospective case-control study in hospital dermatology departments in 8 sub-Saharan African countries over a 12-month period (October 2013 to September 2014). Each case of acute leg cellulitis was matched with 2 controls for age (±5 years) and sex. We analysed the general and local factors. During the study period, 364 cases (223 female, 141 male) were matched with 728 controls. The mean age was 42.15±15.15 years for patients and 42.11±36 years for controls. Multivariate analysis showed the following to be independent risk factors associated with leg erysipelas in our study: obesity (odds ratio [OR]=2.82 ; 95% confidence interval: 2.11-3.76), lymphoedema (OR=3.87, 95%CI: 2.17-6.89), voluntary cosmetic depigmentation (OR=4.29, 95%CI: 2.35-7.83), neglected traumatic wound (OR=37.2, 95%CI: 24.9-57.72) and toe-web intertrigo (OR=37.86, 95%CI: 22.27-64.5). The results of this study confirms the major role of local risk factors (toe-web intertrigo, lymphoedema) previously identified in other geographical settings. However, the originality of our study consists of the identification of voluntary cosmetic depigmentation as a risk factor for leg erysipelas in sub-Saharan Africa.

Full Text Available Cet article est essentiellement consacré à l'étude du fonctionnement limite des paliers lisses lubrifiés à la graisse ; son but est de permettre la détermination des conditions nécessaires à l'obtention d'un film lubrifiant d'épaisseur suffisante. L'auteur cherche à cette occasion une loi théorique qui permet de départager les régimes de lubrification, non plus empiriquement, mais sur la base de lois statistiques. La formulation finale doit permettre aux utilisateurs de situer correctement les conditions de fonctionnement d'un palier lisse et d'en estimer la sécurité du régime. This article deals essentially with the boundary behaviour of plain bearings lubricated by grease. Its aim is to determine the conditions required to obtain a sufficiently thick lubricating film. The author proposes a theoretical law for separating lubrication types. This law is not empirical but is based on statistical laws. The final formulation should enable users to correctly situate the operating conditions of a plain bearing and to evaluate the safety factor during running.

Cervicofacial cellulitises are dominated by dental affections. The aim of this study is to describe etio-epidemiological and therapeutic aspects of cervicofacial cellulitis of dental cause at the CNHU-HKM in Cotonou (Benin). It's a retrospective study from 1998 to 2007 included patients with inflammatory cervicofacial tumefaction of dental cause. A glycaemia, a HIV serology and a blood formula numeration are realized. Some patients practiced standard oral and dental radio. Patients were hospitalized and received mono, bi or triple antibiotic. Lancing with swab of pus for cytobacteriological and antibiogram examination was realized for some of patients. Dental cares were been systematic. 68 cases whose 53 dental cause where been collected 77.94%. Bracket concern patients between 0-20 and 20-40 years old (64.15%). Males were, more concerned. Dental traumatisms find again (18.88%), tooth decay (56.60%) and 24.53% patients practiced dental extraction. Anti inflammatory practiced by 67.92% patients associated to antibiotic in 41.51% cases. The three latest molar were concerned to 26 patients. Among those last 22 had attack of mandibular teeth. Treatment consisted in lancing drainage to 2/3 patients in 83.40% cases associated to tri antibiotic. Evolution has been favourable with recovery to 86.67%; 6 decreases to 13.33% cases. Cervicofacial cellulitises are dangerous, rapidly responsible of deceases by extension. A better oral and dental hygiene would improved prognosis.

Purpose: Delayed breast cellulitis (DBC) is characterized by the late onset of breast erythema, edema, tenderness, and warmth. This retrospective study analyzes the risk factors and clinical course of DBC. Methods and Materials: From 1985 through 2004, 580 sequential women with 601 stage T0-2N0-1 breast cancers underwent breast conserving therapy. Cases of DBC were identified according to accepted clinical criteria: diffuse breast erythema, edema, tenderness, and warmth occurring >3 months after definitive surgery and >3 weeks after radiotherapy. Potential risk factors analyzed included patient comorbidity, operative technique, acute complications, and details of adjunctive therapy. Response to treatment and long-term outcome were analyzed to characterize the natural course of this syndrome. Results: Of the 601 cases, 16%, 52%, and 32% were Stage 0, I, and II, respectively. The overall incidence of DBC was 8% (50/601). Obesity, ecchymoses, T stage, the presence and aspiration of a breast hematoma/seroma, removal of >5 axillary lymph nodes, and arm lymphedema were significantly associated with DBC. The median time to onset of DBC from the date of definitive surgery was 226 days. Ninety-two percent of DBC patients were empirically treated with antibiotics. Fourteen percent required more invasive intervention. Twenty-two percent had recurrent episodes of DBC. Ultimately, 2 patients (4%) underwent mastectomy for intractable breast pain related to DBC. Conclusion: Although multifactorial, we believe DBC is primarily related to a bacterial infection in the setting of impaired lymphatic drainage and may appear months after completion of radiotherapy. Invasive testing before a trial of antibiotics is generally not recommended

Serratia marcescens is an unusual cause of severe skin infection initially described in immunocompromised patients. We report a case of necrotizing cellulitis of the leg caused by S marcescens in a 68-year-old woman with diabetes mellitus and a history of chronic lymphoedema of the leg. We reviewed the literature and found 49 cases of severe skin infections from S marcescens that included 20 cases of necrotizing fasciitis (NF) as well as 29 cases of severe skin infections without NF (non-NF cases). Patients were immunocompromised in 59% to 70% of cases. The mortality rate was high in NF cases (60%) versus non-NF cases (3%). Surgery was required in 95% of NF cases and in 24% of non-NF cases. The other clinical manifestations of S marcescens skin infection reported in the literature included disseminated papular eruptions in patients infected with human immunodeficiency virus with folliculitis on the trunk. Serratia marcescens is naturally resistant to amoxicillin alone and amoxicillin associated with clavulanic acid. Broad-spectrum antibiotics are indicated to treat S marcescens skin infections, and surgery should be promptly considered in cases of severe skin infections if appropriate antibiotic therapy does not lead to rapid improvement.

An epizootic of ulcerative to nodular ventral dermatitis was observed in a large breeding colony of 8-month to 5-year-old leopard geckos (Eublepharis macularius) of both sexes. Two representative mature male geckos were euthanized for diagnostic necropsy. The Chrysosporium anamorph of Nannizziopsis vriesii (CANV) was isolated from the skin lesions, and identification was confirmed by sequencing of the internal transcribed spacer region of the rRNA gene. Histopathology revealed multifocal to coalescing dermal and subcutaneous heterophilic granulomas that contained septate fungal hyphae. There was also multifocal epidermal hyperplasia with hyperkeratosis, and similar hyphae were present within the stratum corneum, occasionally with terminal chains of arthroconidia consistent with the CANV. In one case, there was focal extension of granulomatous inflammation into the underlying masseter muscle. This is the first report of dermatitis and cellulitis due to the CANV in leopard geckos.

Full Text Available Bites from brown recluse spiders (Loxosceles reclusa result in several clinical manifestations, causing painful, disfiguring necrotic ulcers and, uncommonly, severe systemic effects. We report two cases reports with necrotic arachnidism from Turkey. A 21-year-old man was admitted to our clinic with the complaints of pruritis, redness on his neck. He had a history of spider bite one day ago. A 52-year-old woman had a cellulitis with hemorrhagic lesion and superficial necrosis on her arm and had a history of spider bite one day ago. Based on these clinical and epidemiological findings, a diagnosis of necrotic arachnidism was suspected, and the diagnosis of necrotic arachnidism was confirmed with these typical skin lesions and spiders bites in histories of patients. The outcome of our patients were good after antihistaminic, antibiotic, analgesic and anti-inflammatory treatments. The brown recluse spider is notorious for its necrosisinducing bite. Its venom contains a rare toxin, sphingomyelinase D, which activates the vascular endothelium and initiates a cascade of activation of neutrophils and granulocyte macrophage colony-stimulating factor, resulting in tissue destruction. In many cases, diagnosis of spider bite is very difficult. Therefore, clinical and epidemiological findings, as well as a detailed history, may establish the diagnosis.

Lisse et al. [Lisse, C.M., Kraemer, K.E., Nuth III, J.A., Li, A., Joswiak, D., 2007. Icarus 187, 69-86] recently presented a new analysis of an ISO spectrum of Comet C/1995 O1 (Hale-Bopp), from which they claimed the identification of many new dust species. Among them are PAHs, which were not found in our first analysis of the ISO spectra. We present here a re-examination of the ISO observations of Comet Hale-Bopp. From the absence of PAHs features in the 5.25-8.5 μm region, we infer that PAHs are at least twice less abundant than derived by Lisse et al. The carbonate feature at 7.00 μm is marginally present, but lower by a factor 2 to 3 than predicted by the model of Lisse et al.

Hospital admissions for non-purulent lower extremity cellulitis (NLEC) are common and can be prolonged and costly. Newer treatment options and preventive strategies are expected to result in cost savings before implementation, but few studies have quantified the cost of conventional treatment. Using the Rochester Epidemiology Project, the incidence of NLEC in Olmsted County, MN in 2013 was 176.6 per 100,000 persons. The subset of patients who required hospitalization for NLEC in 2013 was determined. Hospital admissions were analyzed retrospectively using standardized cost analysis within several relevant categories. Thirty-four patients had an average hospital length of stay of 4.7 days. The median total inpatient cost was $7,341. The median cost per day was $2,087, with 49% due to room and board. Antibiotics administered for treatment of NLEC contributed a median cost of $75 per day of hospitalization, and laboratory and imaging test costs were $73 and $44, respectively, per day of hospitalization. Hospitalizations for NLEC can be costly and prolonged with room and board accounting for much of the cost. Therefore, newer management strategies should seek to reduce hospital length of stay and/or avoid inpatient admission to reduce cost.

A high pressure experimental water loop has been made for studying the detection and evolution of cladding failure in a pressurized reactor. The loop has been designed for a maximum temperature of 360 deg. C, a maximum of 160 kg/cm{sup 2} and flow rates up to 5 m{sup 3}/h. The entire loop consists of several parts: a main circuit with a canned rotor circulation pump, steam pressurizer, heating tubes, two hydro-cyclones (one de-gasser and one decanter) and one tubular heat exchanger; a continuous purification loop, connected in parallel, comprising pressure reducing valves and resin pots which also allow studies of the stability of resins under pressure, temperature and radiation; following the gas separator is a gas loop for studying the recombination of the radiolytic gases in the steam phase. The preceding circuits, as well as others, return to a low pressure storage circuit. The cold water of the low pressure storage flask is continuously reintroduced into the high pressure main circuit by means of a return pump at a maximum head of 160 kg /cm{sup 2}, and adjusted to the pressurizer level. This loop is also a testing bench for the tight high pressure apparatus. The circulating pump and the connecting flanges (Oak Ridge type) are water-tight. The feed pump and the pressure reducing valves are not; the un-tight ones have a system of leak recovery. To permanently check the tightness the circuit has been fitted with a leak detection system (similar to the HRT one). (author)Fren.

Probst Corina

2010-08-01

Full Text Available Abstract Background Cryptococcus neoformans is an encapsulated yeast and the most frequent cryptococcal species found in humans. Cryptococcosis is considered an opportunistic infection as it affects mainly immunosuppressed individuals. In humans, C. neoformans causes three types of infections: pulmonary cryptococcosis, cryptococcal meningitis and wound or cutaneous cryptococcosis. Case Presentation An 81-year-old woman developed severe necrotizing cellulitis on her left arm without any preceding injury. The patient had been treated with systemic corticosteroids over twenty years for rheumatoid arthritis (RA. Skin biopsies of the wound area were initially interpreted as cutaneous vasculitis of unknown etiology. However, periodic acid Schiff staining and smear analysis later revealed structures consistent with Cryptococcus neoformans, and the infection was subsequently confirmed by culture. After the initiation of therapy with fluconazole 400 mg per day the general condition and the skin ulcers improved rapidly and the patient was discharged to a rehabilitation facility. Subsequently surgical debridement and skin grafting were performed. Conclusions Opportunistic infections such as cryptococcosis can clinically and histologically mimic cutaneous vasculitis and have to be investigated rigorously as a differential diagnosis in immunosuppressed patients.

Within the framework of the 'Rapsodie' fast reactor program, prototype plutonium fuel elements are irradiated and then examined in an {alpha} {beta} {gamma} laboratory at Saclay. This laboratory consists of five in line cells and a lead enclosure microscope. Each cell contains an {alpha} sealed removable box 4 ft 3 in. high, 4 ft 11 in. wide and 5 ft 1 in. deep, fitted with one or two magnetic transmission indirect manipulators. The boxes are contained in an {beta} {gamma} shielded enclosure whose front face is constructed of cast iron panels 21-2/3 in. thick. Nitrogen circulating in a closed loop forms the atmosphere of the boxes. This laboratory is essentially intended for metallurgical research. The functions of the various cells are as follows: transferring and packing, cutting, density measurement and cathodic etching, storage and metallography. Work on radioactive materials began in April 1961. Operational incidents have always been of a material nature only.

Clóvis Cechim Junior

Full Text Available ABSTRACT The knowledge on reliable estimates of areas under sugarcane cultivation is essential for the Brazilian agribusiness, since it helps in the development of public policies, in determining prices by sugar mills to producers and allows establishing the logistics of production disposal. The objective of this work was to develop a methodology for mapping the sugarcane crop area in the state of Paraná, Brazil, using images from the Landsat/TM/OLI and IRS/LISS-3 satellites, for the crop years from 2010/2011 to 2013/2014. The mappings were conducted through the supervised Maximum likelihood classification (Maxver achieving, on average, an overall accuracy of 94.13% and kappa index of 0.82. The correlation with the official data of the IBGE ranged from moderate to strong (0.64 ≤ rs ≤ 0.80 with average agreement (dr of 0.81. There was an increase of 2.73% (18,630 ha in the area with sugarcane in Paraná between 2010/2011 and 2013/2014.

Within the framework of the 'Rapsodie' fast reactor program, prototype plutonium fuel elements are irradiated and then examined in an {alpha} {beta} {gamma} laboratory at Saclay. This laboratory consists of five in line cells and a lead enclosure microscope. Each cell contains an {alpha} sealed removable box 4 ft 3 in. high, 4 ft 11 in. wide and 5 ft 1 in. deep, fitted with one or two magnetic transmission indirect manipulators. The boxes are contained in an {beta} {gamma} shielded enclosure whose front face is constructed of cast iron panels 21-2/3 in. thick. Nitrogen circulating in a closed loop forms the atmosphere of the boxes. This laboratory is essentially intended for metallurgical research. The functions of the various cells are as follows: transferring and packing, cutting, density measurement and cathodic etching, storage and metallography. Work on radioactive materials began in April 1961. Operational incidents have always been of a material nature only.

La muestra estuvo constituida por 75 pacientes que presentaron síntomas y signos de celulitis para lo cual se les realizó un minucioso examen físico general y regional, tanto extraoral como intraoral. El sexo masculino resultó ser el más afectado con 42 pacientes y el grupo de edades más dañado fue el de 35 a 59 años. La región anatómica superficial externa mentoniana estuvo involucrada en 36 casos. La misma región mentoniana pero en su porción vestibular inferior se destacó con 51 pacientes. De las regiones anatómicas profundas, la submandibular predominó en 51 individuos para un 68,0 %.

In order to investigate the capability of satellite images for Pistachio forests density mapping, IRS-P6-LISS IV data were analyzed in an area of 500 ha in Iran. After geometric correction, suitable training areas were determined based on fieldwork. Suitable spectral transformations like NDVI, PVI and PCA were performed. A ground truth map included of 34 plots (each plot 1 ha) were prepared. Hard and soft supervised classifications were performed with 5 density classes (0-5%, 5-10%, 10-15%, 15-20% and > 20%). Because of low separability of classes, some classes were merged and classifications were repeated with 3 classes. Finally, the highest overall accuracy and kappa coefficient of 70% and 0.44, respectively, were obtained with three classes (0-5%, 5-20%, and > 20%) by fuzzy classifier. Considering the low kappa value obtained, it could be concluded that the result of the classification was not desirable. Therefore, this approach is not appropriate for operational mapping of these valuable Pistachio forests.

ERS-2 SAR and IRS-1C LISS III data fusion: A PCA approach to improve remote sensing based geological interpretation

Science.gov (United States)

Pal, S. K.; Majumdar, T. J.; Bhattacharya, Amit K.

Fusion of optical and synthetic aperture radar data has been attempted in the present study for mapping of various lithologic units over a part of the Singhbhum Shear Zone (SSZ) and its surroundings. ERS-2 SAR data over the study area has been enhanced using Fast Fourier Transformation (FFT) based filtering approach, and also using Frost filtering technique. Both the enhanced SAR imagery have been then separately fused with histogram equalized IRS-1C LISS III image using Principal Component Analysis (PCA) technique. Later, Feature-oriented Principal Components Selection (FPCS) technique has been applied to generate False Color Composite (FCC) images, from which corresponding geological maps have been prepared. Finally, GIS techniques have been successfully used for change detection analysis in the lithological interpretation between the published geological map and the fusion based geological maps. In general, there is good agreement between these maps over a large portion of the study area. Based on the change detection studies, few areas could be identified which need attention for further detailed ground-based geological studies.

Genotypes and pathogenicity of cellulitis isolates reveal traits that modulate APEC virulence.

Full Text Available We characterized 144 Escherichia coli isolates from severe cellulitis lesions in broiler chickens from South Brazil. Analysis of susceptibility to 15 antimicrobials revealed frequencies of resistance of less than 30% for most antimicrobials except tetracycline (70% and sulphonamides (60%. The genotyping of 34 virulence-associated genes revealed that all the isolates harbored virulence factors related to adhesion, iron acquisition and serum resistance, which are characteristic of the avian pathogenic E. coli (APEC pathotype. ColV plasmid-associated genes (cvi/cva, iroN, iss, iucD, sitD, traT, tsh were especially frequent among the isolates (from 66.6% to 89.6%. According to the Clermont method of ECOR phylogenetic typing, isolates belonged to group D (47.2%, to group A (27.8%, to group B2 (17.4% and to group B1 (7.6%; the group B2 isolates contained the highest number of virulence-associated genes. Clonal relationship analysis using the ARDRA method revealed a similarity level of 57% or higher among isolates, but no endemic clone. The virulence of the isolates was confirmed in vivo in one-day-old chicks. Most isolates (72.9% killed all infected chicks within 7 days, and 65 isolates (38.1% killed most of them within 24 hours. In order to analyze differences in virulence among the APEC isolates, we created a pathogenicity score by combining the times of death with the clinical symptoms noted. By looking for significant associations between the presence of virulence-associated genes and the pathogenicity score, we found that the presence of genes for invasins ibeA and gimB and for group II capsule KpsMTII increased virulence, while the presence of pic decreased virulence. The fact that ibeA, gimB and KpsMTII are characteristic of neonatal meningitis E. coli (NMEC suggests that genes of NMEC in APEC increase virulence of strains.

The authors describe a method of determining electrolytes (Na, K, CI) and phosphorus in small fragments of muscle taken from child patients by needle biopsy. This method has been used to study muscular disturbances in hydroelectrolytic illnesses of childhood, whether acute, such as dehydration or toxicosis in infants, or chronic, such as malnutrition or marasmus. The results are discussed in the light of parallel data obtained by other methods of investigation. The authors also discuss the possibility of using this method to estimate intra-cellular hydroelectrolytic disorders in child pathology.

Classism might be the downside of the prevailing ideologies of individual responsibility for success. However, since studies into perceived classism have mainly been qualitative, little is known about its association with socioeconomic status, health, health behaviours and perceived inferiority, especially in more egalitarian countries. This study, therefore, examined the associations of perceived classism with socioeconomic status, health, health behaviours and perceived inferiority. We used cross-sectional data (2012/2013) from the Dutch Longitudinal Internet Studies for the Social Sciences (LISS) (n = 1540; age 16-90; 46.9 % men). We found that classism was perceived by 18.2 % of the participants, with the lowest income and occupation group most likely to perceive classism (22.0 and 27.5 %, respectively). Perceived classism was significantly associated with poor health (e.g. self-rated health OR = 2.44, 95 % CI = 1.76-3.38) and feelings of inferiority (e.g. shame OR = 4.64, 95 % CI = 3.08-6.98). No significant associations were found with health behaviours. To further examine the role of perceived classism for socioeconomic differences in health and its association with country-level socioeconomic inequalities, prevailing ideologies, and objective opportunities for social mobility, we recommend more longitudinal and international studies with comparable measures of perceived classism.

non completamente risolto per talune condizioni patologiche, nelle quali i dati obiettivi ed anamnestici sono relativamente uniformi e il quadro radiologico privo di qualsiasi caratteristica. Materiale e metodi: Il materiale � costituito da sei casi di istiocitosi delle cellule di Langherans della mandibola osservati nell'arco di un decennio. Lo studio � basato sulla valutazione della documentazione radiologica tradizionale. Le radiografie sono state eseguite in proiezione latero-laterale-obliqua che, come noto, libera quasi completamente la porzione orizzontale della mandibola dalla sovrapposizione delle immagini di altre strutture ossee. Risultati: I risultati delle indagini radiologiche sono riportati nella tabella I. Si tratta di reticoloendoteliopatie capaci di dar luogo ad un processo granulomatoso costituito da polinucleati eosinofili, plasmacellule e linfociti e, fondamentalmente, da grandi cellule istiocitarie mononucleate dotate di attivit� granulopessica e fagocitaria, spiccatamente proliferanti nel tessuto osseo, identificabili con le cellule di Langherhans della pelle, delle mucose, degli spazi periodontali, del midollo osseo. Il tessuto granulomatoso che ne deriva si infiltra tra gli elementi costitutivi dell'organo colpito ed estendendosi comprime, atrofizza e tende a distruggere il tessuto, sostituendosi ad esso. Le alterazioni determinate dal granuloma isiocitario di Langherhans prevalgono nettamente nel sistema scheletrico e si verificano, in ordine di frequenza, nel cranio, nelle ossa lunghe dell'estremit�, nel piede, nelle coste e nella colonna vertebrale. L'interessamento della mucosa orale � eccezionale. Conclusioni: Nel granuloma istiocitario unifocale di Langherhans della mandibola l'indagine radiologica � indispensabile per l'approccio allo studio della tumefazione premandibolare fermo restando che la diagnosi di natura si basa esclusivamente sulla biopsia. Oltre all'esame radiologico digitale o

Les polymyosites (PM) sont des connectivites très rares, d’étiologie inconnue, dotées d'un grand polymorphisme clinique et évolutif. Elles peuvent être associées à d'autres manifestations viscérales notamment pulmonaires telles que la pneumopathie interstitielle. Ces complications respiratoires sont souvent associées à un taux de mortalité élevé. Les cas de pneumonie organisée révélatrice de polymyosite sont rarement rapportés dans la littérature et de description récente.

La biopsie musculaire a confirmé le diagnostic de la myosite. L’évolution était favorable sous corticothérapie. Le traitement de la PO associée au PM n'est pas clairement établi. La corticothérapie constitue le traitement de première intention. PMID:25722789

avantages que presente l'emploi de composes trities pour l'autoradiographie. En effet les electrons du tritium ont une energie maximum de 0,018 MeV, correspondant a un parcours d'environ 1 micron dans une emulsion photographique, ce qui permet d'obtenir le plus fort degre de resolution possible aux niveaux cellulaire et infracellulaire. Ce phenomene est particulierement utile pour l'etude du metabolisme de tissus comme la moelle osseuse, qui sont composes de differents types de cellules a divers stades de differenciation. Cette technique a ete utilisee pour l'etude du metabolisme des acides nucleiques et des proteines des cellules normales et leucemiques de la moelle osseuse. L'auteur a etudie le metabolisme de l'ADN a l'aide d'un precurseur specifique, la thymidine tritiee. Il a decele certaines differences importantes dans les pourcentages de cellules marquees, en comparant les elements normaux et leucemiques au meme stade de maturation. Il a constate, en particulier, que dans les cellules d'un sujet atteint de leucemie aiguee, le taux d'incorporation de la thymidine etait beaucoup plus faible, ce qui prouve une diminution de la capacite de proliferation de ces cellules par rapport aux myeloblastes normaux. L'auteur a utilise la meme technique pour etudier le metabolisme de l'ARN et des proteines, a l'aide des precurseurs suivants: uridine, leucine et phenylalanine tritiees. Il est maintenant admis en biologie cellulaire qu'il existe un rapport etroit entre le metabolisme de l'ARN et celui des proteines; l'auteur a demontre qu'il existait egalement un rapport constant entre l'incorporation de l'uridine et des acides amines, dans les cellules normales de la moelle osseuse. Dans les cellules de sujets atteints de leucemie aiguee, l'incorporation de l'ARN et des precurseurs protidiques, bien qu'elle differe dans chaque cas, est toujours nettement plus faible. De plus, le rapport entre l'incorporation de l'uridine et celle des amino-acides varie constamment dans ces cellules

Caracterisation thermique de modules de refroidissement pour la photovoltaique concentree

Science.gov (United States)

Collin, Louis-Michel

Pour rentabiliser la technologie des cellules solaires, une reduction du cout d'exploitation et de fabrication est necessaire. L'utilisation de materiaux photovoltaiques a un impact appreciable sur le prix final par quantite d'energie produite. Une technologie en developpement consiste a concentrer la lumiere sur les cellules solaires afin de reduire cette quantite de materiaux. Or, concentrer la lumiere augmente la temperature de la cellule et diminue ainsi son efficacite. Il faut donc assurer a la cellule un refroidissement efficace. La charge thermique a evacuer de la cellule passe au travers du recepteur, soit la composante soutenant physiquement la cellule. Le recepteur transmet le flux thermique de la cellule a un systeme de refroidissement. L'ensemble recepteur-systeme de refroidissement se nomme module de refroidissement. Habituellement, la surface du recepteur est plus grande que celle de la cellule. La chaleur se propage donc lateralement dans le recepteur au fur et a mesure qu'elle traverse le recepteur. Une telle propagation de la chaleur fournit une plus grande surface effective, reduisant la resistance thermique apparente des interfaces thermiques et du systeme de refroidissement en aval vers le module de refroidissement. Actuellement, aucune installation ni methode ne semble exister afin de caracteriser les performances thermiques des recepteurs. Ce projet traite d'une nouvelle technique de caracterisation pour definir la diffusion thermique du recepteur a l'interieur d'un module de refroidissement. Des indices de performance sont issus de resistances thermiques mesurees experimentalement sur les modules. Une plateforme de caracterisation est realisee afin de mesurer experimentalement les criteres de performance. Cette plateforme injecte un flux thermique controle sur une zone localisee de la surface superieure du recepteur. L'injection de chaleur remplace le flux thermique normalement fourni par la cellule. Un systeme de refroidissement est installe

Primary extraintestinal complications caused by Yersinia enterocolitica are extremely rare, especially in the form of skin and soft-tissue manifestations, and little is known about their clinical characteristics and treatments. We presented our case and reviewed past cases of primary skin and soft-tissue infections caused by Y enterocolitica. We report a case of primary cellulitis and cutaneous abscess caused by Y enterocolitica in an immunocompetent 70-year-old woman with keratodermia tylodes palmaris progressiva. She presented to an outpatient clinic with redness, swelling, and pain of the left ring finger and left upper arm without fever or gastrointestinal symptoms 3 days before admission. One day later, ulceration of the skin with exposed bone of the proximal interphalangeal joint of the left ring finger developed, and cefditoren pivoxil was described. However, she was admitted to our hospital due to deterioration of symptoms involving the left finger and upper arm. Cefazolin was initiated on admission, then changed to sulbactam/ampicillin and vancomycin with debridement of the left ring finger and drainage of the left upper arm abscess. Wound culture grew Y enterocolitica serotype O:8 and methicillin-sensitive Staphylococcus aureus. Blood cultures were negative and osteomyelitis was ruled out. Vancomycin was switched to ciprofloxacin, then skin and soft-tissue manifestations showed clear improvement within a few days. The patient received 14 days of ciprofloxacin and oral amoxicillin/clavulanate and has since shown no recurrence. We reviewed 12 cases of primary skin and soft-tissue infections caused by Y enterocolitica from the literature. In several past cases, portal entry involved failure of the skin barrier on distal body parts. Thereafter, infection might have spread to the regional lymph nodes from the ruptured skin. Y enterocolitica is typically resistant to aminopenicillins and narrow-spectrum cephalosporins. In most cases, these inefficient

increased with the increase of the concentration of the TH{sup 3} administered. After an incubation period which lasted 120 min no labelled mitosis was found. Further, the incorporation pattern was the same whether the label was added at the beginning of the incubation or after 160 min. Addition of TH{sup 3} to the same suspension at various time intervals did not alter the per cent of labelled cells but the number of grains per nucleus rose after every administration of the TH{sup 3}. Not all the cells in the suspension incorporated the same amount of TH{sup 3}. Quantitative measurements were made including grain counts, and the results showed that there is probably a deficiency of thymidine available to the leukaemic cells in their ascitic fluid. The dichotomy between the synthesis of the full complement of DNA and subsequent division of the cell will be discussed.

Full Text Available The Topographic maps and Aerial Photographs are used for morphometric analysis of drainage basins and mapping contours with drainage. The stereo pairs of 2.5 m resolution Cartosat 1, Indian satellite 2 and merged data with 5.5 m resolution P6 Resourcesat 1 LISS 4 Indian satellite of 2001 is used to map, rills, gullies, and streams of first order to evaluate part of drainage basin of Cooum and Poondi Reservoir in Thiruvallur taluk of Tamil Nadu state. The Geo Eye latest 2011data is also used with Catrosat 1Stereo data to study present morphology of tiny micro watersheds to study the use of High resolution data for delineation and codification of watersheds. This study area is in an inter fluvial drainage basin of Cooum and Kusasthalai rivers. Kusasthalai river drains in Poondi reservoir which is about 50 km from Chennai. The excess water from Kosasthalai is also diverted through Kesawaram weir to Cooum river which passes through Thiruvallur and Chennai city before it's confluence with Bay of Benegal in the east. As Cooum basin is at higher elevation, water for irrigation is again diverted through chain of tanks to Kusasthalai river basin to drain in Poondi reservoir. Delineation of water sheds in this fluvial basin is difficult by manual survey as man made irrigation channels, natural drainage streams etc., have to be clearly identified. The streams of various orders are identified based on Strahler stream order hierarchy of tributaries, slops and contours using large scale satellite data. The micro water sheds are delinated identifying the ridges from Catrosat data for this interfluves basin which has mild slop. To illustrate this research, parts of two micro watersheds which were delineated using 1:50000 data for Tamil Nadu watershed Atlas up to 7th order streams are taken up for a detailed study using high resolution data. 19 Micro watersheds with streams up to 10th order are mapped.

The flare-up phenomenon in endodontics: a clinical perspective and review.

Science.gov (United States)

Matusow, R J

1988-06-01

The acute endodontic cellulitis exacerbation, which can be potentially fatal, is a definitive entity in endodontic flare-ups. Aerobic microbes, particularly streptococci, are the predominant causative microbes isolated. There was a noticeable absence of obligate anaerobes. This is significant for the selection of an antibiotic for therapy. Treatment parameters were presented. An endodontic cellulitis exacerbation is most unlikely with obligate anaerobes. An endodontic flare-up perspective was attempted with some clinical parameters. The proponents of routine one-visit endodontic treatment with prophylactic drugs to prevent cellulitis exacerbations do not appear to offer any advantage to the more traditional approaches to endodontic treatment of the patient, which may be more beneficial.

Radiations and chemical mutagens kill cells in numerous ways: by one of several kinds of induced dominant lethality, by a direct inactivation of function as with sperm, and by genetically undefinable types of death which may or may not be related to dominant lethality per se. Also, chemical mutagens appear to exert a curious enhancement of the fertilizing capacity of sperm. The different stages of oflgenesis and spermatogenesis respond with unequal sensitivity to radiation, and individual cells pass through stages conferring as much as a 50-fold difference in sensitivity. Where species of Diptera, Hymenoptera and Coleoptera can be compared, a striking similarity of response to radiation can be observed, both to stage sensitivity and degree of response with dose. The silkworm, Bombyx mori (Lepidoptera), seems to be similar in most respects to representatives of the other orders in response of germ cells to radiation, but differs sharply in types of dominant lethality induced. Species having atypical genetic mechanisms (e.g.,the lecanoid system of Planococcus citri (Hemipt. : Coccidae) are special cases, and their responses to radiation are considerably modified from those of other species. For insect population control by the irradiation-of-male method, dominant lethality is as advantageous in species where matings are multiple as in species where mating occurs once. Sperm inactivation and gonial killing can be regarded as instances of true sterility and are maximally effective only in species where mating occurs once. For most efficient control, doses should be chosen which would induce maximum dominant lethality, minimum sperm inactivation and complete killing of gonial cells. These parameters are simple to determine by gamete viability measurements, irradiated and unirradiated population competition experiments and histological examination of gonia.

Risultati. Le alterazioni apoptotiche nelle cellule HEp-2 sono apparse entro 24 ore dall’esposizione alla camptoicina, mentre i segni di necrosi si sono evidenziati più precocemente. La luminescenza si è dimostrata significativamente superiore nei sieri ANA positivi che nei controlli ANA negativi. Gli antcorpi antinucleari sieirici riconoscono meglio gli antigeni da cellule apoptotiche e necrotiche rispetto ai controlli che non hanno subito trattamenti chimici. Conclusioni. L’apoptosi e la necrosi incrementano la capacità legante degli ANA attraverso una migliore disponibilità di antigeni intracellulari o svelando epitopi criptici.

B-cell depletion and primary Sjögren’s syndrome: is there a role for rituximab?

Full Text Available L’idea che la deplezione dei B linfociti potesse essere utilizzata per il trattamento delle malattie reumatiche sistemiche deriva dall’ipotesi che, eliminando le cellule alterate dal circolo, si possa curare la malattia. In realtà, nelle malattie reumatiche sistemiche, contrariamente a quanto accade nei linfomi, la deplezione dei B linfociti persiste per alcuni mesi e successivamente si assiste alla riacutizzazione della malattia. Molteplici sono le ipotesi che possono spiegare tale evento: a insufficiente deplezione dei cloni patogeni; b persistenza di anticorpi patogeni; c alterazione primaria o secondaria della tolleranza dei B linfociti; d ricomparsa delle B cellule; e reminiscenza della malattie da parte di cellule diverse dai B linfociti, probabilmente T linfociti (1, 2...

Cellulitis is a very common condition that often recurs. The PATCH II study was designed to explore the possibility of preventing future episodes of cellulitis, with resultant cost savings for the NHS. This was the first trial to be undertaken by the UK Dermatology Clinical Trials Network. As such, it was the first to test a recruitment model that involved many busy clinicians each contributing just a few patients.

È stata, inoltre, valutata la presenza sulla superficie di tali cellule di recettori specifici per tale induttore, TNFR1 e TNFR2. Materiali e metodi: Gli autoanticorpi anti-La ed anti-Ro sono stati purificati su una colonna cromatografia ad alta affinità. Le metodiche utilizzate per la valutazione della produzione di TNF-α e lo studio dei recettori di superficie sono state immunofluorescenza, RT-PCR e saggi immunoenzimatici. Risultati: I nostri risultati hanno dimostrato che le cellule A-253 esprimono in superficie i recettori TNFR1 e TNFR2 e che gli autoanticorpi anti-Ro e anti-La sono in grado di indurre la produzione di TNF-α nelle stesse cellule. Conclusioni: Il trattamento con gli autoanticorpi anti-Ro ed anti-La induce la produzione di TNF-α in cellule di ghiandole salivari umane e questo potrebbe spiegare la attivazione della via estrinseca della apoptosi.

This research thesis reports the study of possibility of treatments (or restoration) of a mouse which has been submitted to a lethal dose of X rays. More particularly, the author compared the restoring efficiency of bone marrow and fetal liver injected in a mouse which had been lethally irradiated by a total exposure to X rays. He also studied the functional status of the hemopoietic graft, and the emergence of the secondary disease in mice which had been as well lethally irradiated and then restored by injection of bone marrow and fetal liver. The author then addressed the influence of the induction of immune tolerance of the host with respect to the donor on the survival of a mouse lethally irradiated and restored by homologue bone marrow [French] Des resultats des recherches que nous avons conduites permettent, dans les limites de nos conditions experimentales, d'eclaircir certains aspects du probleme de la restauration des animaux irradies par la greffe de cellules hemopoietiques.

An 11-month-old Malay child presented with a gunshot-like wound over the forehead following sling shot injury. On examination, he had a deep circular laceration wound over the forehead, measuring 2.0 cm in diameter, with minimal bleeding. There was no obvious foreign body seen inside the wound and no palpable foreign body surrounding the wound. The gunshot-like wound was associated with left preseptal cellulitis. A skull X-ray showed a white opaque foreign body in the left frontal bone. Computed tomography (CT scan of orbit and brain revealed a left comminuted fracture of the left orbital roof, and left frontal brain contusion with prelesional edema. Wound exploration was performed and revealed a 0.5 cm unshattered marble embedded in the left frontal bone. The marble and bone fragments were removed. The left preseptal cellulitis responded well to intravenous antibiotic and topical antibiotic. Keywords: preseptal cellulitis, orbital roof fracture, pediatric trauma

Objective: To study the imaging appearance of deep neck space cellulitis and abscess and to evaluate the diagnostic criteria of deep neck space infection. Methods: CT and MRI findings of 28 cases with deep neck space infection proved by clinical manifestation and pathology were analyzed, including 11 cases of retropharyngeal space, 5 cases of parapharyngeal space infection, 4 cases of masticator space infection, and 8 cases of multi-space infection. Results: CT and MRI could display the swelling of the soft tissues and displacement, reduction, or disappearance of lipoid space in the cellulitis. In inflammatory tissues, MRI imaging demonstrated hypointense or isointense signal on T 1 WI, and hyperintense signal changes on T 2 WI. In abscess, CT could display hypodensity in the center and boundary enhancement of the abscess. MRI could display obvious hyperintense signal on T 2 WI and boundary enhancement. Conclusion: CT and MRI could provide useful information for deep neck space cellulitis and abscess

If rats are sacrificed within minutes after an injection of acetate 1 - {sup 14}C the specific radioactivities of sterols precipitable with digitonine, extracted from liver parenchyma cells and from Kupffer cells are very close to each other, whatever the duration of the experiment may be. It follows that cholesterol synthesis probably occurs in both types of cells. A validation of this conclusion requires that the validity of certain assumptions be established.

An approach to box homogenisation-lattice properties

International Nuclear Information System (INIS)

Paul, O.P.K.

1978-01-01

A computer code has been developed to solve two group coupled neutron diffusion equations in x, y geometry for a lattice cell of a thermal reactor comprising an array of fuel pins (cellules) regularly spaced in a square box. The method uses finite difference approximation considering four neighbours of a mesh point and successive iteration technique. To simulate the current vanishing boundary condition at the cell boundary, the code uses an hypothesis that the thermal neutron flux increases exponentially beyond the pin cellules boundary while the fast neutron flux follows the reverse behaviour and the flux across the cell boundary follows the mirror image distribution. The code requires two group diffusion properties of pin cellules as input data and it calculates Ksub(infinity), L 2 , Lsub(infinity)sup(2), Dsub(th), and Df of the system. This code coupled with lattice pin and global calculation codes has been used for IRT - 2000 reactor and the results are quite reasonable. (author)

2011-01-01

Full Text Available Background: Two major therapeutic principles can be employed for the treatment of distal femoral fractures: retrograde intramedullary (IM nailing (RN or less invasive stabilization on system (LISS. Both operative stabilizing systems follow the principle of biological osteosynthesis. IM nailing protects the soft-tissue envelope due to its minimally invasive approach and closed reduction techniques better than distal femoral locked plating. The purpose of this study was to evaluate and compare outcome of distal femur fracture stabilization using RN or LISS techniques. Materials and Methods: In a retrospective study from 2003 to 2008, we analyzed 115 patients with distal femur fracture who had been treated by retrograde IM nailing (59 patients or LISS plating (56 patients. In the two cohort groups, mean age was 54 years (17-89 years. Mechanism of injury was high energy impact in 57% (53% RN, 67% LISS and low-energy injury in 43% (47% RN, 33% LISS, respectively. Fractures were classified according to AO classification: there were 52 type A fractures (RN 31, LISS 21 and 63 type C fractures (RN 28, LISS 35; 32% (RN and 56% (LISS were open and 68% (RN and 44% (LISS were closed fractures, respectively. Functional and radiological outcome was assessed. Results: Clinical and radiographic evaluation demonstrated osseous healing within 6 months following RN and following LISS plating in over 90% of patients. However, no statistically significant differences were found for the parameters time to osseous healing, rate of nonunion, and postoperative complications. The following complications were treated: hematoma formation (one patient RN and three patients LISS, superficial infection (one patient RN and three patients LISS, deep infection (2 patients LISS. Additional secondary bone grafting for successful healing 3 months after the primary operation was required in four patients in the RN (7% of patients and six in the LISS group (10% of patients

Chemical facial cellulitis, while commonly seen in domestic accidents or attempted suicide, is uncommon in the dental office and hence rarely addressed in the dental literature. We present an unusual case of chemical facial cellulitis caused by inadvertent injection of formalin into the soft tissues of the oral cavity, which was mistaken for local anesthesia solution. This report comprises the immediate symptoms, possible root cause, and management of the difficult situation. We also provide some guidelines to avoid such unfortunate events.

2015-12-01

Full Text Available Introduction: Cellulitis remains a very serious disease even today. Mortality, which varied between 10–40%, has been reduced owing to the standard securing of airway patency and use of an appropriate surgical treatment approach. Materials and methods: A total of 195 patients were hospitalised for cellulitis at the University Hospital in Hradec Králové during 2007–2011. The following parameters were evaluated: age, gender, dependence of incidence of the disease on the season of the year, frequency of attacks of the particular areas and their clinical characteristics, aetiology of the inflammation, types of patient complaints, prevalence of current systemic diseases, results of microbiological and selected laboratory analyses, socio-economic status of the patients, and duration of patient stay at the hospital. Statistical analysis was performed by using Pearson’s correlation coefficient, the statistical significance level was p < 0.05. Results: The mean age of the patients was 39.8 years. The group of 195 patients included 108 (55% males and 87 (45% females. The mean time between the first symptoms of the disease and admission to the Department was 5 days. From among the 195 patients, 116 (59.5% were working persons, 79 (40.5% were non-working (children, students, unemployed persons, women on maternity leave, retired people. The odontogenic origin of the disease was verified in 173 (88.7% patients. In total, 65 (33.3% patients had no coinciding complicating systemic disease, 22 (11.3% patients had diabetes mellitus. The most frequent symptom of cellulitis was painful swelling, found in 194 (99.5% patients, followed by jaw contracture, found in 153 (78.5% patients. Conclusion: The results are largely very similar to those of previous studies performed in other countries, except that we found no correlation between the prevalence of cellulitis and the socio-economic status, nor have we confirmed Klebsiella pneumoniae sp. as the cause of

Eddy current proximity measurement of perpendicular tubes from within pressure tubes in CANDU nuclear reactors

2018-04-01

Fuel channels in CANDU® (CANada Deuterium Uranium) nuclear reactors consist of two non-concentric tubes; an inner pressure tube (PT) and a larger diameter calandria tube (CT). Up to 400 horizontally mounted fuel channels are contained within a calandria vessel, which also holds the heavy water moderator. Certain fuel channels pass perpendicularly over horizontally oriented tubes (nozzles) that are part of the reactor's liquid injection shutdown system (LISS). Due to sag, these fuel channels are at risk of coming into contact with the LISS nozzles. In the event of contact between the LISS nozzle and CT, flow-induced vibrations from within the moderator could lead to fretting and deformation of the CT. LISS nozzle proximity to CTs is currently measured optically from within the calandria vessel, but from outside the fuel channels. Measurement by an independent means would provide confidence in optical results and supplement cases where optical observations are not possible. Separation of PT and CT, known as gap, is monitored from within the PT using a transmit-receive eddy current probe. Investigation of the eddy current based gap probe as a tool to also measure proximity of LISS nozzles was carried out experimentally in this work. Eddy current response as a function of LISS-PT proximity was recorded. When PT-CT gap, PT wall thickness, PT resistivity and probe lift-off variations were not present this dependence could be used to determine the LISS-PT proximity. This method has the potential to provide LISS-CT proximity using existing gap measurement data. Obtaining LISS nozzle proximity at multiple inspection intervals could be used to provide an estimate of the time to LISS-CT contact, and thereby provide a means of optimizing maintenance schedules.

L'angiomyolipome rénal est une tumeur qui est reconnue bénigne. Elle présente trois composantes différentes: musculaire, vasculaire et graisseuse, dont la distribution est variable. Le diagnostic repose sur la mise en évidence de la composante graisseuse intra-tumorale en TDM ou IRM. Exceptionnellement la tumeur peut avoir un caractère agressive avec extension locorégionale et veineuse (la veine rénale et la veine cave inferieure). Nous présentons une observation d'une patiente âgée de 37 ans présentant un Angiomyolipome rénal volumineux avec extension à la veine rénale. PMID:29599888

Improvement of a Clinical Score for Necrotizing Fasciitis: 'Pain Out of Proportion' and High CRP Levels Aid the Diagnosis.

Necrotizing fasciitis (NF) is a rare mono-/polymicrobial skin infection that spreads to underlying tissues. NF is quickly progressing and leads to life threatening situations. Immediate surgical debridement together with i.v. antibiotic administration is required to avoid fatal outcome. Early diagnosis is often delayed due to underestimation or confusion with cellulitis. We now compared the initial clinical and laboratory presentation of NF and cellulitis in detail to assess if a typical pattern can be identified that aids timely diagnosis of NF and avoidance of fatal outcome. 138 different clinical and laboratory features of 29 NF patients were compared to those of 59 age- and gender matched patients with severe erysipelas requiring a subsequent hospitalization time of ≥10 days. Differences in clinical presentation were not obvious; however, NF patients suffered significantly more often from strong pain. NF patients exhibited dramatically elevated CRP levels (5-fold, p>0.001). The overall laboratory risk indicator for necrotizing fasciitis (LRINEC) score was significantly higher in NF patients as compared to cellulitis. However, a modification of the score (alteration of laboratory parameters, addition of clinical parameters) led to a clear improvement of the score with a higher positive predictive value without losing specificity. In summary, clinical differentiation of NF from cellulitis appears to be hard. 'Pain out of proportion' may be an early sign for NF. An improvement of the LRINEC score emphasizing only relevant laboratory and clinical findings as suggested may aid the early diagnosis of NF in the future leading to improvement of disease outcome by enabling rapid adequate therapy.

funzionamento di cellule macrofagiche stabilizzate e coltivate in vitro (RAW 264.7) responsabili dei meccanismi di difesa specifica e aspecifica del sistema immunitario. Sono stati, inoltre, standardizzati due diversi sistemi espositivi operanti a 900 MHz a differenti livelli di densita' di potenza (da 1 a 100 W/m{sup 2}) per garantire condizioni elettromagnetiche omogenee, idonee condizioni di incubazione delle cellule e la riproducibilita' degli esperimenti. Il lavoro di standardizzazione dei sistemi espositivi e i risultati sperimentali di questa ricerca, che hanno evidenziato differenze significative della crescita e della funzionalita' macrofagica solo al livello di densita' di potenza piu' elevato (100 W/m{sup 2}), ma recuperare dopo 48 ore dall'esposizione, risultano essere preliminari e propedeutici per una programmazione sperimentale futura atta ad approfondire una valutazione bio-tossicologica in vitro.

There is a paucity of knowledge regarding nationally representative estimates of hospital-based emergency department (ED) visits for dental problems made by people with mental health conditions. The authors conducted a study to provide nationwide estimates of hospital-based ED visits attributed to dental caries, pulpal and periapical lesions, gingival and periodontal lesions and mouth cellulitis/abscess made by people with mental health conditions. The authors used the Nationwide Emergency Department Sample, which is a component of the Healthcare Cost and Utilization Project sponsored by the Agency for Healthcare Research and Quality. ED visits attributable to dental caries, pulpal and periapical lesions, gingival and periodontal lesions and mouth cellulitis/abscess were identified by the emergency care provider by using diagnostic codes in International Classification of Diseases, Ninth Revision, Clinical Modification. The authors examined outcomes, including hospital charges. They used simple descriptive statistics to summarize the data. In 2008, people with mental health conditions made 15,635,253 visits to hospital-based ED in the United States. A diagnosis of dental caries, pulpal and periapical lesions, gingival and periodontal lesions and mouth cellulitis/abscess represented 63,164 of these ED visits. The breakdown of the ED visits was 34,574 with dental caries, 25,352 with pulpal and periapical lesions, 9,657 with gingival and periodontal lesions, and 2,776 with mouth cellulitis/abscess. The total charge for ED visits in the United States was $55.46 million in 2008. In 2008, people with mental health conditions made 63,164 visits to hospital-based EDs and received a diagnosis of dental caries, pulpal and periapical lesions, gingival and periodontal lesions or mouth cellulitis/abscess. These ED visits incurred substantial hospital charges. Programs designed to reduce the number of ED visits made by this population for common dental problems could have a

Examining the correlation between diabetes and odontogenic infection: A nationwide, retrospective, matched-cohort study in Taiwan.

Full Text Available More than 90% of head and neck infections are caused by pathological changes originating in the teeth. When odontogenic infections are not properly treated, infections may spread to distant spaces and cause more serious infections in fascial spaces, ultimately leading to deep neck infections. Clinical experience has indicated that patients with diabetes mellitus (DM may be more susceptible to facial cellulitis and deep neck infections caused by odontogenic infections. This study used the Taiwan National Health Insurance Database (NHIRD to analyze and examine the correlation between DM and odontogenic infections in patients. To this end, this study analyzed 1 million NHIRD individual datasets from 2005, of which 964,182 individuals had medical treatment records. The insurance database also recorded related factors such as age, sex, duration of hospital stays, season, and whether patients were low income. We also analyzed the correlation between urbanization and the studied diseases. The results indicated that the correlation between facial cellulitis and DM patients was confirmed; facial cellulitis was most likely to occur 2 years after the initial DM diagnosis, with a risk occurrence 1.409 times greater than that of the control group. Facial cellulitis is more likely to occur in patients originating from poorer socioeconomic backgrounds, and female DM patients are more likely to experience this condition. These conclusions may facilitate the establishment of clinical guidelines for preventative education and treatment. Oral prevention and health education for high-risk patients, as well as early-stage surgical intervention and antibiotic usage in early-stage odontogenic infections, can prevent disease progression, improve patient recovery rates, and reduce the use and waste of medical resources.

This study was designed to compare the CT findings and clinical manifestations in children and adolescents with acute sialadenitis according to the involved salivary glands. The study included fifty children and adolescents (34 boys, 16 girls) with acute sialadenitis that was diagnosed during the past five years. All of the subjects were divided into three groups: group I (parotid gland involvement, n = 16), group II (submandibular gland involvement, n = 20) and group III (involvement of both glands, n 14). We analyzed the presence of an abscess, sialolith, bilaterality, cellulitis and lymphadenopathy on CT scans. The analyzed clinical data were age, sex, lymphadenopathy, pain, swelling, presence of a mass, tonsillitis, treatment period and surgical treatment if it was performed. The presence of an abscess, sialolith, cellulitis, swelling, age, presence of a palpable mass and treatment period were statistically significant factors for the patients in the three groups. An abscess was combined only in group I patients. There was a high rate of sialolith in group II patients and cellulitis in group III patients as seen on CT scans. Swelling in group II patients and group III patients and the presence of a palpable mass in group I patients were identified as clinical manifestations. Age was younger in group I patients (mean age, 5.3 years) than in group II patients (mean age, 12.9 years) and group III patients (mean age, 15.2 years). The treatment period was longer for group I patients. For acute sialadenitis in children and adolescents, age, presence of an abscess, sialolith, cellulitis, swelling, presence of a palpable mass and treatment period were different according to the involved salivary glands

Encapsulation of tritiated wastes in hot laboratories

From 1962 to 1976, one of the laboratories called ''Cellule 4'', was equipped to produce large quantities of tritium. The decisions taken in June 1976 to redirect the activities of the Radioisotopes Department included the suspension of the tritium activities of ''Cellule 4'' at the Saclay Nuclear Research Center. From 1976 to 1981, many CEA departments contributed to the design and implementation of a packaging procedure for tritiated wastes resulting from the dismantling of ''Cellule 4''. A classification into three groups was adopted for this purpose. (1) Packaging in a welded stainless steel container. (2) Packaging in a reinforced concrete shell lined internally with a thick coat of epoxy resin charged with sand. (3) Packaging in a reinforced concrete shell lined internally with a thin coat of epoxy resin. The dismantling operations were carried out in three phases. (1) (2 1/2 months): the T activity remained unchanged during this period and waste selection was carried out. (2) (2 1/2 months): waste dismantling and packaging of groups (2) and (3) were carried out in this phase. Activity decayed rapidly. (3) (2 months): the work performed included the loosening and cutting of the general structures [fr

Constructing elliptic curves from Galois representations

Snowden, Andrew; Tsimerman, Jacob

2017-01-01

Given a non-isotrivial elliptic curve over an arithmetic surface, one obtains a lisse $\\ell$-adic sheaf of rank two over the surface. This lisse sheaf has a number of straightforward properties: cyclotomic determinant, finite ramification, rational traces of Frobenius, and somewhere not potentially good reduction. We prove that any lisse sheaf of rank two possessing these properties comes from an elliptic curve.

Material influence on biocontamination level and adhering cell physiology Influence des matériaux sur le niveau de biocontamination et la physiologie des cellules adhérentes

Full Text Available Dans la plupart des environnements, les microorganismes vivent préférentiellement au sein de biofilms. De nombreux facteurs influencent leur formation i.e. les nutriments, la température, le régime du fluide environnent, la microflore et les matériaux. Dans le mécanisme de biocontamination, décrit en quatre étapes successives, l'adhésion initiale est un élément clé de la bioadhésion et les matériaux un élément majeur pour son contrôle. L'acier inoxydable est très utilisé dans de nombreux secteurs d'activité pour sa bonne nettoyabilité et son excellente résistance à la corrosion. Pour se différencier, certains matériaux mettent en avant d'autres propriétés. Ainsi, la sélection du matériau le mieux adapté à un problème donné nécessite de connaitre son aptitude à la biocontamination ainsi que son impact sur la physiologie des microorganismes. Pour tous les matériaux testés, la mortalité des bactéries adhérentes est inférieure à 55 %. Les résultats obtenus ont montré qu'un matériau dit antimicrobien n'induit pas plus de cellules endommagées comparativement aux autres matériaux. In most environments, association with a surface in a structure known as a biofilm is the prevailing microbial lifestyle. Several factors may influence the biofilm formation e.g. nutrients, temperature, flow velocity, initial microflora and the nature of materials. Considering the biocontamination mechanism described in four steps, the initial adhesion is a key element in the biocontamination phenomenon and the substratum is of major concern in controlling bacterial adhesion. Stainless steel is well used in numerous markets because of its high cleanability and corrosion resistance properties. However, other materials are put forward by focusing on properties which differentiate them from those of stainless steel. Thereby, to select the material best suited to the problem, there should have data on their aptitude for

HISTORIQUE : La lombalgie chronique est une douleur lombaire persistante d’origine multifactorielle. Le niveau de douleur initial reste faiblement utilisé pour analyser et comparer les réponses des patients lombalgiques au programme de reconditionnement. OBJECTIFS : Apprécier et évaluer les réponses des sujets lombalgiques chroniques très douloureux à une prise en charge dynamique et intensive. MÉTHODOLOGIE : 144 sujets atteints de lombalgie chronique ont été inclus dans un programme de restauration fonctionnelle du rachis de 5 semaines. Les sujets ont été classés en deux groupes de niveau de douleur: un groupe atteint de douleur sévère (n = 28) et un groupe atteint de douleur légère à modérée (n = 106). L’ensemble des sujets ont bénéficié d’une prise en charge identique comprenant principalement de la kinésithérapie, de l’ergothérapie, du reconditionnement musculaire et cardio-vasculaire ainsi qu’un suivi psychologique. Les paramètres physiques (flexibilité, force musculaire) et psychologiques (qualité de vie) ont été mesurés avant (T0) et après le programme (T5sem). RÉSULTATS : L’ensemble des performances physiques et fonctionnelles des sujets très douloureux sont moins bonnes et le retentissement de la lombalgie sur la qualité de vie, pour ces mêmes sujets, est majoré à T0. Toutes les différences significatives constatées à T0 entre les deux groupes s’effacent à T5sem. CONCLUSIONS : Les sujets lombalgiques chroniques très douloureux répondent favorablement au programme dynamique et intensif. L’intensité douloureuse de la lombalgie n’aurait pas d’effet sur les réponses au programme. La restauration fonctionnelle du rachis apporterait aux sujets la possibilité de mieux gérer leur douleur quel que soit son niveau. PMID:25299476

Following an intravenous injection of potassium-42 as indicator, an analysis of the specific activity vs. time curve in arterial plasma, in venous plasma efferent from the kidney, in urine and in various regions of the kidney of rabbits reveals that: 1) The turnover rate of potassium in the cortex cells (proximal and distal convoluted tubes) is very large, being limited only by renal blood flow. 2) The turnover rate of potassium in deep regions (Henle loops and collector tubules) is much smaller. 3) Potassium in the urine comes from cells of the convoluted tubes and not from cells of Henle loops, collector ducts, or glomerular filtrate. 4) Any potassium filtered at the level of the glomerules would be entirely reabsorbed at the level of the proximal tube, while total potassium in the urine results from a process of excretion by cells of the distal tube. These results are comparable with the assumption that the movement of potassium between interstitial medium and convoluted tube cells results from entirely passive processes.

Liu, Alexander; Pusalkar, Pawan

2011-01-01

A 19-year-old male presented with periorbital cellulitis responsive to intravenous antibiotics. A routine ECG on admission showed slurred upstroke of the QRS complexes consistent with Wolff–Parkinson–White syndrome (WPW). He has never experienced any cardiac-related symptoms. Once the periorbital cellulitis resolved, he was referred to the specialist cardiology ablation clinic. He was counselled on the arrythmogenic risks of untreated WPW and the potential complications of radiofrequency catheter ablation (RFCA). He decided to go ahead with electrophysiological studies and RFCA, which took place successfully. This case highlights the importance of routine ECG in the diagnosis of asymptomatic WPW. The use of prophylactic ablation of asymptomatic WPW is controversial and should be considered on a case-specific basis. PMID:22693197

Pelvic Surgical Site Infections in Gynecologic Surgery

Directory of Open Access Journals (Sweden)

Mark P. Lachiewicz

2015-01-01

Full Text Available The development of surgical site infection (SSI remains the most common complication of gynecologic surgical procedures and results in significant patient morbidity. Gynecologic procedures pose a unique challenge in that potential pathogenic microorganisms from the skin or vagina and endocervix may migrate to operative sites and can result in vaginal cuff cellulitis, pelvic cellulitis, and pelvic abscesses. Multiple host and surgical risk factors have been identified as risks that increase infectious sequelae after pelvic surgery. This paper will review these risk factors as many are modifiable and care should be taken to address such factors in order to decrease the chance of infection. We will also review the definitions, microbiology, pathogenesis, diagnosis, and management of pelvic SSIs after gynecologic surgery.

Experience in ultrasonic gap measurement between calandria tubes and liquid injection shutdown systems nozzles in Bruce Nuclear Generating Station

International Nuclear Information System (INIS)

Abucay, R.C.; Mahil, K.S.; Goszczynski, J.J.

1995-01-01

The gaps between calandria tubes (CT) and Liquid Injection Shutdown System (LISS) nozzles at the Bruce Nuclear Generating Station ''A'' (Bruce A) are known to decrease with time due to radiation induced creep/sag of the calandria tubes. If this gap decreases to a point where the calandria tubes come into contact with the LISS nozzle, the calandria tubes could fail as a result of fretting damage. Proximity measurements were needed to verify the analytical models and ensure that CT/LISS nozzle contact does not occur earlier than predicted. The technique used was originally developed at Ontario Hydro Technologies (formerly Ontario Hydro Research Division) in the late seventies and put into practical use by Research and Productivity Council (RPC) of New Brunswick, who carried out similar measurements at Point Lepreau NGS in 1989 and 1991. The gap measurement was accomplished y inserting an inspection probe, containing four ultrasonic transducers (2 to measure gaps and 2 to check for probe tilt) and a Fredericks electrolytic potentiometer as a probe rotational sensor, inside LISS Nozzle number-sign 7. The ultrasonic measurements were fed to a system computer that was programmed to convert the readings into fully compensated gaps, taking into account moderator heavy water temperature and probe tilt. Since the measured gaps were found to be generally larger than predicted, the time to CT/LISS nozzle contact is now being re-evaluated and the planned LISS nozzle replacement will likely be deferred, resulting in considerable savings

Purpose: We reported on the clinical approaches of ophthalmology and otorhinolaryngology departments in the treatment of the orbital complications of sinusitis. We also included an in-depth literature review. Methods: We retrospectively reviewed the medical files of 51 patients from January 2008 to January 2014. The records were evaluated for age, gender, type of orbital complications, symptoms, predisposing factors, imaging studies, medical and surgical management, culture results, and follow-up information. SPSS version 15.0 software (Statistical Analysis, The Statistical Package for Social Sciences Inc, Chicago, IL) was used for the statistical analysis. Results: Fifty-one patients met the criteria, with available medical records, for the study (29 male, 22 female). Thirty-two (62.7%) were diagnosed with preseptal cellulitis and 19 (37.3%) with postseptal cellulitis. After a detailed evaluation, 15 were diagnosed with a subperiosteal abscess (SPA), and 4 were diagnosed with orbital cellulitis. The age and gender was similar for the two groups. Five patients with medial SPA were treated with endoscopic sinus surgery, one patient with inferior SPA was treated with external surgery, and six patients with other localizations were treated with a combination of endoscopic sinus surgery and external surgery. All patients presented with periorbital erythema and edema. The length of hospitalization and duration of symptoms were similar in both groups. Visual acuity was between 1/10 to 10/10 (mean 7/10) and statistically significant for preseptal and postseptal cellulitis groups (p<0.001). All patients received intravenous antibiotics upon the first day of admission. Conclusion: Orbital complications of acute sinusitis required intensive follow-up and a multidisciplinary approach. A contrast-enhanced paranasal sinus computerized tomography (CT) scan can detect the extent of the infection. An initial trial of intravenosus (IV) antibiotics may be appropriate when close

Studying a disease with no home - lessons in trial recruitment from the PATCH II study

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Cellulitis is a very common condition that often recurs. The PATCH II study was designed to explore the possibility of preventing future episodes of cellulitis, with resultant cost savings for the NHS. This was the first trial to be undertaken by the UK Dermatology Clinical Trials Network. As such, it was the first to test a recruitment model that involved many busy clinicians each contributing just a few patients. Methods A double-blind randomised controlled trial comparing prophylactic antibiotics (penicillin V with placebo tablets, for the prevention of repeat episodes of cellulitis of the leg. Primary outcome was time to subsequent recurrence of cellulitis. Results The PATCH II study was closed to recruitment having enrolled 123 participants from a target of 400. Whilst the recruitment period was extended by 12 months, it was not possible to continue beyond this point without additional funds. Many factors contributed to poor recruitment: (i changes in hospital policy and the introduction of community-based intravenous teams resulted in fewer cellulitis patients being admitted to hospital; ii those who were admitted were seen by many different specialties, making it difficult for a network of dermatology clinicians to identify suitable participants; and iii funding for research staff was limited to a trial manager and a trial administrator at the co-ordinating centre. With no dedicated research nurses at the recruiting centres, it was extremely difficult to maintain momentum and interest in the study. Attempts to boost recruitment by providing some financial support for principal investigators to employ local research staff was of limited success. Discussion The model of a network of busy NHS clinicians all recruiting a few patients into large clinical studies requires further testing. It did not work very well for PATCH II, but this was probably because patients were not routinely seen by dermatologists, and recruitment

A high temperature apparatus for vapour pressure measurements by Knudsen effusion method is described. Sample is heated in a tungsten cell in an electronic bombardment furnace. Several critical factors affecting the accuracy of measurements such as: - temperature distribution and measurement in the effusion cell, - CLAUSING factor and molecular flow, - compatibility between cell material and sample heated, are discussed with careful attention. Vapour pressure of UO{sub 2} has been studied between 2200 and 2800 K. Experimental points fit a curve expressed by: logP{sub mm} = 12.4264 - (3.3184/T * 10{sup 4}/T) which is in good agreement with previous results of literature.

To describe the characteristics of patients admitted in hospitals with soft tissue infections, and analyse the variables whose died, in order to define risk groups. retrospective analysis of medical reports of all patient admitted during 2002 year for soft tissue infections in public malacitans hospitals. We excluded the patient with soft tissue infections associated with burns, surgery, pressure ulcers, and orbit cellulitis. We analysed clinical, biochemical variables and indications for yields and imaging tests, so the empiric antibiotic treatment established and its correlations with practice guidelines. We analysed 391 admissions of 374 patients. Cellulitis was the most frequent diagnosis (69.3%). We did imaging tests in 51.6%. In 94.3% of cases were treated with empirics antibiotics. The most prescribed drug was amoxiciline plus clavulanate (39%). 27 patients died, 40.7% of them for septic cause. All deceased patients had chronic diseases. The only biochemical parameters associated with mortality were serum proteins and albumina (55 +/- 9 g/L vs. 63 +/- 8 g/L; p = 0.0231) and (22 +/- 7 g/L vs. 29 +/- 7 g/L; p = 0.0125) respectively. Cellullitis are the most frequent soft tissue infections that requires admissions in hospitals. We overuse imaging test and don t follow the practice guidelines recommendations in antibiotic therapy. Primary soft issue infection s mortality is low and it s restricted to people with chronic illness, deep infections and bad nutritional status.

Dose effect relations concerning inhibition of clone formation by kidney cells of human origin in culture after irradiation with monoenergetic neutrons of about 3-MeV and about 15-MeV energy, are reported. For 3-MeV neutrons the dose rate was equal to 0.2 rad/min, while for 15-MeV neutrons dose rates of 2.7 rad/min and 12 rad/min were obtained. The cells were irradiated in culture dishes with a thin Melinex bottom and in small flexible nylon and silicon rubber tubes. Neutron fluxes were determined by measuring the activation of sulphur pellets mounted respectively between the dishes and the tubes. Calculation of the dose on the basis of the neutron flux presented a number of problems which are discussed. Because no radiation equilibrium exists around the cells, the resulting inaccuracies in the dose determinations are investigated. Dose-survival curves for both types of neutrons are presented. For 3-MeV neutrons an RBE was found ranging from 6.5 at low doses to about 3.1 at high doses, while for 15-MeV neutrons the RBE varied from 1.9 to 1.6. By comparison of these RBE-values with the RBE-LET relation obtained in earlier experiments with deuterons and {alpha}-particles, it is possible to derive an effective LET for the neutrons used. In order to elucidate certain problems related to the death of experimental animals after X- or neutron- irradiation, a technique has been developed whereby the cells, contained in small tubes, are used to measure the effective dose (i.e . dose corrected for the RBE) at sites of interest in phantoms or animals.

Belanger, Simon

La situation energetique et les enjeux environnementaux auxquels la societe est confrontee entrainent un interet grandissant pour la production d'electricite a partir de l'energie solaire. Parmi les technologies actuellement disponibles, la filiere du photovoltaique a concentrateur solaire (CPV pour concentrator photovoltaics) possede un rendement superieur et mi potentiel interessant a condition que ses couts de production soient competitifs. La methode d'epitaxie par faisceaux chimiques (CBE pour chemical beam epitaxy) possede plusieurs caracteristiques qui la rendent interessante pour la production a grande echelle de cellules photovoltaiques a jonctions multiples a base de semi-conducteurs III-V. Ce type de cellule possede la meilleure efficacite atteinte a ce jour et est utilise sur les satellites et les systemes photovoltaiques a concentrateur solaire (CPV) les plus efficaces. Une des principales forces de la technique CBE se trouve dans son potentiel d'efficacite d'utilisation des materiaux source qui est superieur a celui de la technique d'epitaxie qui est couramment utilisee pour la production a grande echelle de ces cellules. Ce memoire de maitrise presente les travaux effectues dans le but d'evaluer le potentiel de la technique CBE pour realiser la croissance de couches de GaAs sur des substrats de Ge. Cette croissance constitue la premiere etape de fabrication de nombreux modeles de cellules solaires a haute performance decrites plus haut. La realisation de ce projet a necessite le developpement d'un procede de preparation de surface pour les substrats de germanium, la realisation de nombreuses sceances de croissance epitaxiale et la caracterisation des materiaux obtenus par microscopie optique, microscopie a force atomique (AFM), diffraction des rayons-X a haute resolution (HRXRD), microscopie electronique a transmission (TEM), photoluminescence a basse temperature (LTPL) et spectrometrie de masse des ions secondaires (SIMS).

Full Text Available Objectives: The purpose of the study was to establish the role of ultrasonography in determining the involvement of specific fascial spaces in maxillofacial region and the stage of infection, in indicating the appropriate time for surgical intervention and to compare clinical and ultrasonographic findings.Material and Methods: Twenty five patients with fascial space infection in maxillofacial region were subjected to ultrasonographic examination following a detailed clinical and radiological examination. Ultrasonography guided needle aspiration was performed. Based on the findings, patients diagnosed with abscess were subjected to incision and drainage and those with cellulitis were subjected to medical line of treatment.Results: More than one fascial space was involved in all patients. On clinical examination 64 spaces were involved, of them 34 spaces had abscess formation and 30 spaces were in the stage of cellulitis. On ultrasonography examination, 28 spaces were reported to have abscess formation and 36 spaces were diagnosed to be in the stage of cellulitis. On comparative analysis of both clinical and ultrasonographic findings, ultrasonography was found to be sensitive in 65% of the cases and having specificity of 80%. It was registered statistically significant (P < 0.001 agreement between these two methods of assessment (kappa index = 0.814.Conclusions: Ultrasonography is a quick, widely available, relatively inexpensive, and painless procedure and can be repeated as often as necessary without risk to the patient. Thus ultrasonography is a valuable diagnostic aid to the oral and maxillofacial surgeon for early and accurate diagnosis of fascial space infection, their appropriate treatment and to limit their further spread.

Precipitation of uranium oxide by reduction in alkaline solution; Precipitation d'oxyde d'uranium par reduction en milieu alcalin

In the first part of the report the authors study the reaction mechanism for this reduction which makes it possible to precipitate a hydrated uranium oxide from alkaline uranyl carbonate solutions. The research into the effects of different variables on numerous cycles are then summarized. Optical, X-ray and thermogravimetric examinations then make it possible to predict the properties of this oxide. In the second part the authors carry out calculations for the continuous operation of single cells and cells in series. These calculations give the data required for the construction of 2 cells having capacities of 0.3 and 10 litres. Results obtained from the continuous operation of this latter cell lead to certain conclusions concerning the applicability of this method to the hydrometallurgy of uranium. (authors) [French] Dans une premiere partie, les auteurs etudient le mecanisme de reaction de cette reduction qui permet la precipitation d'un oxyde d'uranium hydrate dans les solutions d'uranyle-carbonates alcalins. Les etudes de diverses variables sur de nombreux cycles sont ensuite resumees. Puis des examens optiques, aux rayons X et par thermogravimetrie, permettent de proposer une hypothese sur les proprietes de l'oxyde obtenu. Dans la deuxieme partie, les auteurs developpent un calcul prevoyant la marche continue de cellules uniques et en cascades. De ces calculs on tire les elements permettant la realisation de deux cellules de 0,3 et 10 litres. Des resultats de marche continue sur cette derniere cellule, on peut conclure a l'applicabilite de cette methode a l'hydrometallurgie de l'uranium. (auteurs)

Gadolinium-DTPA-enhanced magnetic resonance imaging of musculoskeletal infectious processes

International Nuclear Information System (INIS)

Hopkins, K.L.; Li, K.C.P.; Bergman, G.

1995-01-01

The purpose of this study was to assess whether gadolinium-enhanced magnetic resonance imaging (MRI) provides diagnostic information beyond that given by nonenhanced imaging in the evaluation of musculoskeletal infectious processes and whether it can be used for differentiating infectious from noninfectious inflammatory lesions. Magnetic resonance images performed with and without intravenous gadolinium-DTPA in 34 cases in which musculoskeletal infection had been clinically suspected were reviewed. Infectious lesions-including osteomyelitis, pyarthrosis, abscess, and cellulitis-were confirmed in a total of 22 cases: in 15 by biopsy or drainage and in 7 by clinical course. Our results show that gadolinium-DTPA-enhanced MRI is a highly sensitive technique in diagnosing musculoskeletal infectious lesions. It is especially useful in distinguishing abscesses from surrounding cellulitis/myositis. Lack of contrast enhancement rules out infection with a high degree of certainty. However, contrast enhancement cannot be used to reliably distinguish infectious from noninfectious inflammatory conditions. (orig.)

Treatment of idiopathic hepatic lipidosis in cats: 11 cases (1986-1987).

Science.gov (United States)

Jacobs, G; Cornelius, L; Allen, S; Greene, C

1989-09-01

Idiopathic hepatic lipidosis was diagnosed in 11 cats. Cats were treated by delivery of balanced nutrients supplemented with L-carnitine via a surgically placed gastrostomy tube. Feeding through the gastrostomy tube was initiated in the hospital and was continued at home in all cats. The mean duration of gastrostomy tube feeding was 48 days (range, 22 to 98 days). Vomiting associated with feeding (3 cats) and localized cellulitis at the gastrostomy site (2 cats) were the most frequent complications. Vomiting was controlled by reducing the volume of food administered at each feeding or by administration of metoclopramide. Cellulitis was treated successfully by parenteral administration of antibiotics and local wound cleansing. Seven of 11 cats (65%) survived and have remained clinically healthy for 15 to 29 months (mean, 20 months) since diagnosis. The other 4 cats died of peritonitis (n = 1), pneumonia (n = 1), hepatic encephalopathy (n = 1), or cardiopulmonary arrest (n = 1) between 0 and 10 days after surgery.

Parameterization and Observability Analysis of Scalable Battery Clusters for Onboard Thermal Management Paramétrage et analyse d’observabilité de clusters de batteries de taille variable pour une gestion thermique embarquée

Directory of Open Access Journals (Sweden)

Lin Xinfan

2013-03-01

Full Text Available Although the battery surface temperature is commonly measured, the core temperature of a cell may be much higher hence more critical than the surface temperature. The core temperature of a battery, though usually unmeasured in commercial applications, can be estimated by an observer, based on a lumped-parameter battery thermal model and the measurement of the current and the surface temperature. Even with a closed loop observer based on the measured surface temperature, the accuracy of the core temperature estimation depends on the model parameters. For such purpose, an online parameterization methodology and an adaptive observer are designed for a cylindrical battery. The single cell thermal model is then scaled up to create a battery cluster model to investigate the temperature pattern of the cluster. The modeled thermal interconnections between cells include cell to cell heat conduction and convection to the surrounding coolant flow. An observability analysis is performed on the cluster before designing a closed loop observer for the pack. Based on the analysis, guidelines for determining the minimum number of required sensors and their exact locations are derived that guarantee the observability of all temperature states. Bien que la température de surface d’une batterie soit généralement mesurée, la température interne d’une cellule peut être beaucoup plus élevée donc plus critique que la température de surface. La température interne d’une batterie, pourtant normalement non mesurée dans les applications commerciales, peut être évaluée par un observateur, sur la base d’un modèle thermique de batterie à constantes localisées et à partir de la mesure du courant et de la température de surface. Même avec un observateur en boucle fermée basé sur la température de surface mesurée, la précision de l’estimation de la température interne dépend des constantes du modèle. Dans cette optique, une méthodologie de

18-F flourodeoxy glucose positron emission tomography-computed tomography imaging: A viable alternative to three phase bone scan in evaluating diabetic foot complications?

International Nuclear Information System (INIS)

Shagos, G. S.; Shanmugasundaram, Palaniswamy; Varma, Ajith Kumar; Padma, Subramanyam; Sarma, Manjit

2015-01-01

This paper is based on the initial findings from a prospective ongoing study to evaluate the efficacy of flourodeoxy glucose positron emission tomography-computed tomography (FDG-PET CT) in diabetic foot evaluation. The aim was to compare the diagnostic accuracies of three phase bone scan (TPBS) and FDG PET-CT (FDG-PET) in diabetic foot evaluation. Seventy-nine patients with complicated diabetic foot (osteomyelitis/cellulitis, Charcot's neuropathy) were prospectively investigated. TPBS (15 mci methylene di phosphonate [MDP] intravenous [IV]), followed by FDG-PET (5 mci IV) within 5 days were performed in all patients. Based on referral indication, patients grouped into Group I, n = 36, (?osteomyelitis/cellulitis) and Group II, n = 43 (?Charcot's neuropathy). Interpretation was based on intensity, extent, pattern of MDP and FDG uptake (standardized uptake value) along with CT correlation. Findings were compared with final diagnostic outcome based on bone/soft tissue culture in Group I and clinical, radiological or scintigraphic followup in Group II. Results: Group I: For diagnosing osteomyelitis, TP: TN: FP: FN were 14:5:2:2 by FDG PET and 13:02:05:03 by TPBS respectively. Sensitivity, specificity, positive predictive value and negative predictive value (NPV) of FDG-PET were 87.5%, 71%, 87.5% and 71% and 81.25%, 28.5%, 72% and 40% for TPBS, respectively. Group II: charcot's: cellulitis: Normal were 22:14:7 by FDG PET and 32:5:6 by TPBS, respectively. Flourodeoxy glucose PET-CT has a higher specificity and NPV than TPBS in diagnosing pedal osteomyelitis. TPBS, being highly sensitive is more useful than FDG-PET in detecting Charcot's neuropathy

'un reacteur et celui de certains circuits radioelectriques usuels. Les fluctuations peuvent alors etre calculees par l'introduction dans le circuit d'une source de bruit convenable. Cette methode nous a permis d'aborder sous une forme particulierement simple l'etude des fluctuations d'ensemble et de preciser la signification physique de certains resultats auxquels conduisent plus laborieusement les autres methodes. L'objet du present rapport est de generaliser cette methode,notamment de l'etendre au cas d'un reacteur ayant une structure en cellules et de l'appliquer a l'etude des fluctuations dans une cellule. On etablit ainsi simplement que les fluctuations dans une cellule sont la resultante de deux termes: - un bruit poissonnien a evolution rapide, non correle avec les fluctuations d'ensemble ; - un bruit a evolution lente, lorsque le reacteur n'est pas trop eloigne de la criticalite, correle avec les fluctuations d'ensemble. Le premier terme provient d'une 'mise en ordre' rapide du systeme, au cours de laquelle les cellules se mettent en equilibre entre elles. Le deuxieme terme traduit l'evolution coordonnee de l'ensemble des cellules, apres extinction de la premiere phase transitoire. Les conclusions de l'etude montrent qu'il serait utile de la completer par une analyse des phenomenes non lineaires qui peuvent influer considerablement sur le comportement transitoire des cellules, pendant la phase ou elles tendent a se mettre en equilibre entre elles. Ce rapport met aussi l'accent sur les liens entre la nouvelle methode et les methodes anterieures. De plus, il tend a faire entrer la theorie des fluctuations des piles dans un cadre plus general, celui des fluctuations d'un systeme dependant de plusieurs parametres aleatoires, et de ce point de vue, la methode pourrait etre aisement transposee et adaptee a l'etude d'autres problemes physiques de ce type.

Discrete symmetries: A broken look at QCD

International Nuclear Information System (INIS)

Goldman, T.

1996-01-01

The alphabet soup of discrete symmetries is briefly surveyed with a view towards those which can be tested at LISS and two particularly interesting cases are called out. A LISS experiment may be able to distinguish CP violation that is not due to the QCD θ term. The elements of a model of parity violation in proton-nucleon scattering, which is consistent with lower energy LAMPF and ANL results, are reviewed in the light of new information on diquarks and the proton spin fraction carried by quarks. The prediction that the parity violating total cross section asymmetry should be large at LISS energies is confirmed. The results of such an experiment can be used both to obtain new information about the diquark substructure of the nucleon and to provide bounds on new right-chiral weak interactions

National trends in ambulatory visits and antibiotic prescribing for skin and soft-tissue infections.

Science.gov (United States)

Hersh, Adam L; Chambers, Henry F; Maselli, Judith H; Gonzales, Ralph

2008-07-28

Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) has emerged as a common cause of skin and soft-tissue infections (SSTIs) in the United States. It is unknown whether this development has affected the national rate of visits to primary care practices and emergency departments (EDs) and whether changes in antibiotic prescribing have occurred. We examined visits by patients with SSTIs to physician offices, hospital outpatient departments, and EDs using the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey from 1997 to 2005. We estimated annual visit rates for all SSTIs and a subset classified as abscess/cellulitis. For abscess/cellulitis visits, we examined trends in characteristics of patients and clinical settings and in antibiotic prescribing. Overall rate of visits for SSTIs increased from 32.1 to 48.1 visits per 1000 population (50%; P = .003 for trend), reaching 14.2 million by 2005. More than 95% of this change was attributable to visits for abscess/cellulitis, which increased from 17.3 to 32.5 visits per 1000 population (88% increase; P trend). The largest relative increases occurred in EDs (especially in high safety-net-status EDs and in the South), among black patients, and among patients younger than 18 years. Use of antibiotics recommended for CA-MRSA increased from 7% to 28% of visits (P < .001) during the study period. Independent predictors of treatment with these antibiotics included being younger than 45 years, living in the South, and an ED setting. The incidence of SSTIs has rapidly increased nationwide in the CA-MRSA era and appears to disproportionately affect certain populations. Although physicians are beginning to modify antibiotic prescribing practices, opportunities for improvement exist, targeting physicians caring for patients who are at high risk.

Cell and tissue structural modifications in hibernating dormice

Directory of Open Access Journals (Sweden)

Manuela Malatesta

2005-06-01

Full Text Available Abstract Tissues and cells of hibernating mammals undergo striking seasonal modifications of their activity through a quiescence-reactivation cycle. During winter, the temperature drastically decreases, the cell timing greatly slows down, the mitotic index sharply falls, DNA, RNA and protein synthesis are drastically reduced; however, upon arousal, all metabolic and physiological activities are quickly restored at the euthermic levels. The physiological, biochemical and behavioural aspects of hibernation have been extensively studied, but data on the morpho-functional relationships of cell and tissue components during the euthermia-hibernation-arousal cycle are rare. In this review, an overview of cell and tissue structural modifications so far reported in hibernating dormice is given and the possible role in the adaptation to the hypometabolic state as well as in the rapid resumption of activities upon arousal is discussed. Riassunto Modificazioni strutturali di cellule e tessuti in Gliridi ibernanti I tessuti e le cellule dei mammiferi ibernanti subiscono profonde modificazioni stagionali della loro attività attraverso un ciclo di quiescenza-riattivazione. Durante l'inverno, la temperatura corporea si abbassa a valori vicini a quelli ambientali, il ciclo cellulare rallenta, l'indice mitotico si riduce notevolmente e la sintesi di DNA, RNA e proteine è drasticamente ridotta. Tuttavia, al risveglio, tutte le attività metaboliche e fisiologiche sono rapidamente ristabilite ai livelli eutermici. Mentre gli aspetti fisiologici, biochimici e comportamentali dell'ibernazione sono stati ampiamenti studiati, i dati sulle relazioni morfo-funzionali dei componenti cellulari e tessutali durante il ciclo eutermia-ibernazione-risveglio sono piuttosto rari. In questo articolo vengono riassunte le attuali conoscenze sulle modificazioni strutturali di cellule e tessuti nei Gliridi ibernanti e viene discusso

To characterise the Emergency Department (ED) prevalence of cellulitis, factors predicting oral antibiotic therapy and the utility of the Clinical Resource Efficiency Support Team (CREST) guideline in predicting patient management in the ED setting, a prospective, cross-sectional study of consecutive adult patients presenting to 3 Irish EDs was performed. The overall prevalence of cellulitis was 12 per 1,000 ED visits. Of 59 patients enrolled, 45.8% were discharged. Predictors of treatment with oral antibiotics were: CREST, Class 1 allocation (odds ratio (OR) 6.81, 95% Cl =1.5-30.1, p=0.012), patient self-referral (OR= 6.2, 95% Cl 1.9- 20.0, p=0.03) and symptom duration longer than 48 hours (OR 1.2, 95% Cl = 1.0-1.5,p=0.049). In conflict with guideline recommendation, 43% of patients in CREST Class 1 received IV therapy. Treatment with oral antibiotics was predicted by CREST Class 1 allocation, self-referral, symptom duration of more than 48 hours and absence of pre-EO antibiotic therapy.

The water hammer analysis code, PTRAN, is used for computation of transient pressures and pressure differentials in the Liquid Injection Shutdown System(LISS) piping network of CANDU-9 to ensure that the design allowables for LEVEL C Service Limit are met for the water hammer loads resulting from the water hammer. The LISS piping network of CANDU-9 has incorporated design improvement in considering the water hammer, such as declining the horizontal part of helium header, and raising the elevation of the overall system piping configuration, etc. The maximum pressure in the LISS piping network is found to be 7.92 MPa(a) at the closed valve in the vent line, which is below the allowable working pressure and the valve design pressure under Level C service conditions. And it is also shown that the maximum pressure in CANDU-9 is much lower than that in CANDU-6

The high resolution now obtainable in sectioned cells studied in the electron microscope offers some promise of visualizing some of the intracellular events leading to the synthesis of proteins. The specificity of incorporation of tritiated thymidine into DNA provides a system which can be accurately followed with respect to time and localization within the cell. The work to be reported here demonstrates that it is possible to study ultra-thin sections of labelled cells in the electron microscope, to remove the specimen after suitable electron micrographs have been taken, to apply a coating of emulsion sufficiently thick to obtain an autoradiograph but still thin enough' to permit re-examination of the specimen in the electron microscope and to obtain electron micrographic images of autoradiography of cells previously recorded. The autoradiographic emulsion was applied as follows: a thin film was formed by dipping a small wire loop into liquid emulsion and transferring the film by passing the loop over the mounted specimen which was fixed to the top of a small plastic peg. Adequate control can be achieved by taking a one-half micron section after each ultra-thin section during sectioning, mounting it on a glass slide and applying conventional autoradiographic techniques. Because of the fragile nature of ultra-thin sections, the yield of successful autoradiographs is quite low. In spite of this objection it is expected that with improvements in skill and techniques the method will facilitate a better understanding of vital cell processes.

Etudes physiques des mélanges eau-cryoprotecteurs

Science.gov (United States)

Vassoille, R.; Perez, J.

The aim of the following review is to present the most important studies concerning the physical properties of water-solutes mixtures used in cryobiology. Cryobiology is a branch of biology which deals with the very low temperature behaviour of cells. This technique is developed today in several directions. The creation of banks of cells and perhaps in a short time of small organs, is the purpose of much research in this domain. Before freezing, living cells are generally put in a solution containing one or more solutes. The role of these solutes is to protect the cells against damage due to crystallization of water (cryoprotectors). The mechanisms of cryoprotection are not well known ; nevertheless the vitreous state formation during cooling is often invoked. So, it is possible to avoid crystallization damage such as mechanical strain (due to an increase of volume of about 10 %) and salt effects (due to osmotic pressure). The conditions in which the vitreous state is obtained, maintained during cooling, storage at low temperature and rewarming can be defined by physical studies presented in the following review. Le présent travail est essentiellement une revue bibliographique des principales études physiques qui ont été réalisées avec des solutions de composés habituellement employés en cryobiologie. La cryobiologie est une branche de la biologie qui s'intéresse au comportement des cellules à basse température. Cette discipline est actuellement en plein développement dans des domaines très divers. Son principal but est la création de banques de cellules de plus en plus complexes avec comme perspective la conservation des organes. Les cellules vivantes sont généralement placées avant congélation dans une solution contenant divers composés dont le rôle est de protéger les cellules contre les effets de la cristallisation de l'eau. L'action protectrice de ces cryoprotecteurs est encore mal connue; cependant, la formation d'un état vitreux lors du

Advances in the physics modelling of CANDU liquid injection shutdown systems

International Nuclear Information System (INIS)

Smith, H.J.; Robinson, R.; Guertin, C.

1993-01-01

The physics modelling of liquid poison injection shutdown systems in CANDU reactors accounts for the major phenomena taking place by combining the effects of both moderator hydraulics and neutronics. This paper describes the advances in the physics modelling of liquid poison injection shutdown systems (LISS), discusses some of the effects of the more realistic modelling, and briefly describes the automation methodology. Modifications to the LISS methodology have improved the realism of the physics modelling, showing that the previous methodology significantly overestimated energy deposition during the simulation of a loss of coolant transient in Bruce A, by overestimating the reactivity transient. Furthermore, the automation of the modelling process has reduced the time needed to carry put LISS evaluations to the same level as required for shutoff-rod evaluations, while at the same time minimizing the amount of input, and providing a method for tracing all files used, thus adding a level of quality assurance to the calculation. 5 refs., 11 figs

CT findings of orbital inflammatory diseases

International Nuclear Information System (INIS)

Kim, Jang Min; Shin, Hyun Joon; Kim, Jung Hyuk; Suh, Won Hyuck

1991-01-01

Twenty-nine patients with orbital inflammatory disease (OIDs) were retrospectively reviewed in order to analyze detailed CT findings which might aid in differentiating OIDs. This study comprised 18 pseudotumors, 5 thyroid ophthalmopathies, and 6 cases of orbital cellulitis. CT scans of the pseudotumors showed various findings such as exophthalmos, scleritis, myositis of the extraocular muscle (MOM), and bone lesion. Bone lesions of the pseudo tumors, which have been rarely reported, were present in 7 cases in our series. Bilateral exophthalmos, myositis, and retrobulbar fat deposition were readily detected by CT in thyroid ophthalmopathy, and, in addition, we found bone erosions involving the orbital apices in 2 cases. In orbital cellulitis, extraorbital soft tissue swelling and lateral displacement of the medial rectus muscle in cases with ethmoiditis were the most conspicuous features. In summary, because of the overlapping CT findings in OIDs, careful examination of CT findings regarding the mode of EOM involvement and the presence or absence of scleritis or sinusitis might help narrow down the differential diagnosis. A pseudotumor with bone lesions could be mistaken as a malignant lesion, and therefore it is necessary to correlate clinical features with CT findings for an accurate diagnosis

Mortality from nonneoplastic skin disease in the United States.

Lott, Jason P; Gross, Cary P

2014-01-01

The mortality burden from nonneoplastic skin disease in the United States is unknown. We sought to estimate mortality from nonneoplastic skin disease as underlying and contributing causes of death. Population-based death certificate data detailing mortality from nonneoplastic skin disease for years 1999 to 2009 were used to calculate absolute numbers of death and age-adjusted mortality by year, patient demographics, and 10 most commonly reported diagnoses. Nonneoplastic skin diseases were reported as underlying and contributing causes of mortality for approximately 3948 and 19,542 patients per year, respectively. Age-adjusted underlying cause mortality (per 100,000 persons) were significantly greater (P deaths occurred in patients ages 65 years and older (34,248 total deaths). Common underlying causes of death included chronic ulcers (1789 deaths/y) and cellulitis (1348 deaths/y). Errors in death certificate data and inability to adjust for patient-level confounders may limit the accuracy and generalizability of our results. Mortality from nonneoplastic skin disease is uncommon yet potentially preventable. The elderly bear the greatest burden of mortality from nonneoplastic skin disease. Chronic ulcers and cellulitis constitute frequent causes of death. Copyright © 2013 American Academy of Dermatology, Inc. Published by Mosby, Inc. All rights reserved.

The aim of this paper was to analyze the causes of orbital cellulitis in connection with covert dental changes as well as to establish the role of radiological procedures in the final diagnosis and further treatment of such cases. Thirty-two patients, aged 25–56, 22 women and 10 men were diagnosed and treated between January 2007 and April 2011 at the Pomeranian Medical University in Szczecin. The patients were examined in the infirmary of the ophthalmological department due to unilateral blepharo-oedema, abrupt pain and vision disturbances; in 5 cases, body temperature increased up to 37.8°C was observed. Next, the patients underwent conventional X-ray examinations of the orbit to exclude any foreign bodies in the eyeball, as well as pantomographies to evaluate the dental status. Visible periapical or periodontal changes in dentition were analyzed with intraoral X-rays with the use of DIGORA System 2.1. Changes found in 3 patients on pantomograms and connected with iatrogenic procedures were further evaluated with CT (64 lines and 128 layers) in frontal, sagittal and axial projections. Orbital disorders were also diagnosed by an ophthalmologist and radiologist with Doppler ultrasound (US) examinations. A linear transducer of 7.5–10 MHz to observe the morphology and vascularity of the eyeball was applied. Iatrogenic treatment was the cause of sinusitis and cellulitis in three cases: incorrectly implanted dental implant in one case, root of the 3 rd molar pushed into the sinus in the second case, and communication between the maxillary alveolar process and the sinus after extraction in case of the third patient. Asymptomatic periapical osteolysis, periodontal disease or dead teeth were found in all cases. Diagnosis of orbital cellulitis of dental origin was determined on the basis of clinical, radiographic and ultrasound findings. Ophthalmologic and dental treatment was applied simultaneously. Co-operation between ophthalmologists, radiologists and dentists is

Developpement d'une methode de Monte Carlo dependante du temps et application au reacteur de type CANDU-6

Science.gov (United States)

Mahjoub, Mehdi

La resolution de l'equation de Boltzmann demeure une etape importante dans la prediction du comportement d'un reacteur nucleaire. Malheureusement, la resolution de cette equation presente toujours un defi pour une geometrie complexe (reacteur) tout comme pour une geometrie simple (cellule). Ainsi, pour predire le comportement d'un reacteur nucleaire,un schema de calcul a deux etapes est necessaire. La premiere etape consiste a obtenir les parametres nucleaires d'une cellule du reacteur apres une etape d'homogeneisation et condensation. La deuxieme etape consiste en un calcul de diffusion pour tout le reacteur en utilisant les resultats de la premiere etape tout en simplifiant la geometrie du reacteur a un ensemble de cellules homogenes le tout entoure de reflecteur. Lors des transitoires (accident), ces deux etapes sont insuffisantes pour pouvoir predire le comportement du reacteur. Comme la resolution de l'equation de Boltzmann dans sa forme dependante du temps presente toujours un defi de taille pour tous types de geometries,un autre schema de calcul est necessaire. Afin de contourner cette difficulte, l'hypothese adiabatique est utilisee. Elle se concretise en un schema de calcul a quatre etapes. La premiere et deuxieme etapes demeurent les memes pour des conditions nominales du reacteur. La troisieme etape se resume a obtenir les nouvelles proprietes nucleaires de la cellule a la suite de la perturbation pour les utiliser, au niveau de la quatrieme etape, dans un nouveau calcul de reacteur et obtenir l'effet de la perturbation sur le reacteur. Ce projet vise a verifier cette hypothese. Ainsi, un nouveau schema de calcul a ete defini. La premiere etape de ce projet a ete de creer un nouveau logiciel capable de resoudre l'equation de Boltzmann dependante du temps par la methode stochastique Monte Carlo dans le but d'obtenir des sections efficaces qui evoluent dans le temps. Ce code a ete utilise pour simuler un accident LOCA dans un reacteur nucleaire de type

We present here the case of a healthy 16-year-old American girl who returned from an organized trip to Israel with cutaneous leishmaniasis caused by Leishmania major; the infection was treated successfully with paromomycin-gentamicin ointment. She was initially misdiagnosed with staphylococcal and pseudomonal cellulitis. Although cutaneous leishmaniasis is seen only rarely in the United States, it should be considered when diagnosing new skin lesions after travel to affected countries.

L'objectif de ce travail est de rapporter une observation particulière de myélome multiple survenant au cours d'une maladie périodique. Il s'agit d'un patient tunisien de 53 ans suivi depuis le jeune âge pour maladie périodique dont le diagnostic était confirmé par l’étude génétique montrant l'homozygotie pour la mutation M694V du gène MEFV, fut admis pour exploration d'une douleur avec tuméfaction fessière droite récente. Les explorations biologiques et radiologiques ont permis de retenir le diagnostic d'un myélome multiple de type IgA à chaînes légères kappa stade III B, associé à une volumineuse localisation plasmocytaire très agressive de l'aile iliaque droite envahissant les structures musculaires avoisinantes. Notre observation, qui à notre connaissance est la deuxième signalant une telle association, se distingue par sa survenue brutale, sa progression rapide et le caractère très agressif de l'hémopathie.

Le lymphome de Burkitt (LB) est une forme de lymphome malin non-Hodgkinien qui provient de l'évolution maligne et de la prolifération de cellules lymphoïdes de type B. Le diagnostic positif repose sur la biopsie d'une masse tumorale ou la ponction de la moelle osseuse révélant la présence de cellules tumorales. Le cas rapporté est celui d'un jeune homme d'une vingtaine d'années qui a été adressé pour des tuméfactions gingivales évoluant depuis 1 mois suite à des extractions dentaires. L'examen anatomopathologique après biopsie complété par l'immunohistochimie conclut à un lymphome de Burkitt. La prise en charge a consisté en une chimiothérapie. Bien que rare, le lymphome de Burkitt est une tumeur agressive qui représente un véritable problème de santé publique d'où la place importante qu'occupe le médecin dentiste dans le diagnostic précoce afin de permettre une prise en charge rapide et appropriée seule garante de la guérison.

Background Cellulite is a 'cottage cheese-like' cutaneous change caused by subcutaneous fat bulging into the dermis that usually leads to cosmetic problems. Slimming cream containing 3.5% water-soluble caffeine and xanthenes exhibits a lipolytic effect with penetration into the dermis. Objective To evaluate the efficacy and safety of slimming cream for the treatment of cellulite. Methods Fifteen subjects with cellulite applied slimming cream to the thighs and inner side of the upper arms twice daily for 6 weeks. Efficacy was assessed using a standard visual scale, changes in the circumferences of the thighs and upper arms, and patient satisfaction by a questionnaire at baseline, week 3, and week 6. Safety was assessed by inquiring about adverse events through questionnaires. Results The standard visual scale score improved significantly by 0.49 points (19.8%) at week 6. Thigh and upper-arm circumferences decreased by 0.7 cm (1.7%) and 0.8 cm (2.3%), respectively, at week 6. Slight itching and transient flushing were commonly reported, but no serious adverse event occurred. Conclusion The slimming cream tested appears to be effective for the treatment of cellulitis without serious adverse effects. However, additional large clinical trials are required to confirm the efficacy and safety of slimming cream for the treatment of cellulitis. PMID:26082579

2006-12-01

The Indian Space Research Organisation (ISRO) has established an operational Remote sensing satellite system by launching its first satellite, IRS-1A in 1988, followed by a series of IRS spacecraft. The IRS-1C/1D satellites with their unique combination of Payloads have taken a lead position in the Global remote sensing scenario. Realising the growing User demands for the "Multi" level approach in terms of Spatial, Spectral, Temporal and Radiometric resolutions, ISRO identified the Resourcesat as a continuity as well as improved RS Satellite. The Resourcesat-1 (IRS-P6) was launched in October 2003 using PSLV launch vehicle and it is in operational service. Resourcesat-2 is its follow-on Mission scheduled for launch in 2008. Each Resourcesat satellite carries three Electro-optical cameras as its payload - LISS-3, LISS-4 and AWIFS. All the three are multi-spectral push-broom scanners with linear array CCDs as Detectors. LISS-3 and AWIFS operate in four identical spectral bands in the VIS-NIR-SWIR range while LISS-4 is a high resolution camera with three spectral bands in VIS-NIR range. In order to meet the stringent requirements of band-to-band registration and platform stability, several improvements have been incorporated in the mainframe Bus configuration like wide field Star trackers, precision Gyroscopes, on-board GPS receiver etc,. The Resourcesat data finds its application in several areas like agricultural crop discrimination and monitoring, crop acreage/yield estimation, precision farming, water resources, forest mapping, Rural infrastructure development, disaster management etc,. to name a few. A brief description of the Payload cameras, spacecraft bus elements and operational modes and few applications are presented.

Observational Trends of Cometary X-ray Emission

Science.gov (United States)

Lisse, C. M.

2001-05-01

The unexpected discovery of x-ray emission from Comet Hyakutake in March 1996 (Lisse et al. 1996) has produced a number of questions about the physical mechanism producing the radiation. The original detection and subsequent observations (Dennerl et al. 1997, Mumma et al. 1997, Krasnopolsky et al. 1998, Owens et al. 1998, Lisse et al. 1999, Lisse et a. 2001, Dennerl et al. 2001) have shown that the very soft (best fit thermal bremsstrahlung model kT = 0.23 keV) emission is due to an interaction between the solar wind and the comet's atmosphere. Using the results from the more than 15 comets detected to date in x-rays, we report on the latest results on cometary x-ray emission. Our emphasis will be on understanding the physical mechanism producing the emission, and using this to determine the nature of the cometary coma and solar wind flux. As-observed morphologies, spectra, and light curves will be discussed. We also report on the status of current cometary observations using the new powerful x-ray observatories Chandra and XMM. This work has been graciously supported by grants from the NASA Planetary Astronomy and Astrophysical Data Programs.

Mills, Janete M.; Schultz, Delray J.; Solin, Lawrence J.

1997-01-01

Purpose: Although the clinical outcome after treatment of ductal carcinoma in situ (DCIS) using breast-conservation surgery and radiation therapy has been well documented, little data has been reported on cosmetic outcome or treatment complications. Therefore, the present study was performed to evaluate cosmesis and complications after breast-conservation treatment for DCIS and to analyze various factors that might affect cosmesis and predispose to complications. Methods and Materials: The records of 90 patients who were alive without evidence of disease with a 3-year minimum follow-up were evaluated for cosmetic results and treatment complications following breast-conservation surgery and radiation therapy for DCIS. Complete gross excision of the primary tumor had been performed in all patients. Additionally, 24 patients had undergone an axillary lymph node dissection in the earlier years of the study. The majority of the patients had received 50-50.4 Gy to the whole breast followed by an electron boost for a total dose of 60-66 Gy. Results: The cosmetic results of 90 evaluable patients at 3 years were: excellent in 69 (77%), good in 19 (21%), and fair in 2 (2%). The cosmetic results of 64 evaluable patients at 5 years were: excellent in 46 (72%), good in 16 (25%), and fair in 2 (3%). Factors associated with worse cosmetic results were an increased volume of tissue excised (>70 cm 3 ) and a negative ipsilateral breast biopsy after radiotherapy. Complications in the 24 patients with an axillary dissection were: arm edema (n = 6), cellulitis of the arm (n = 5), and axillary vein thrombosis (n = 1). Complications in the 66 patients without an axillary dissection were: cellulitis of the arm (n = 1) and cellulitis of the breast (n = 1). Discussion: Breast-conservation surgery followed by radiation therapy achieved excellent or good cosmetic results in 98 and 97% of patients at 3 years and 5 years, respectively. Complications were associated primarily with axillary

electrons de 15 MeV emis par un betatron. Les auteurs presentent les resultats d'une etude autoradiographique sur le comportement de differentes categories de cellules de thymus chez la souris, etude dans laquelle ils ont utilise de la thymidine tritiee comme precurseur de l'ADN. Les donnees sont fonction des modifications du nombre relatif des diverses categories de cellules (par taille), ainsi que du poids de l'organe. Apres irradiation, la proportion des grandes cellules par rapport aux petites augmente; l'incorporation de thymidine tritiee diminue au niveau des grands et petits lymphocytes. Dans la phase aiguee, on n'observe aucune difference notable entre l'effet des rayons X et celui des electrons sur les dimensions des cellules et sur le marquage des grandes cellules. Une modification relative apparait pour le marquage des petites cellules; ce phenomene, qui peut avoir un rapport avec les valeurs EBR des electrons rapides, concorde avec les donnees relatives au poids de l'organe. Pendant la regeneration, les cellules moins differenciees presentent une proliferation active, mais le pourcentage des lymphocytes arrives a maturation reste faible. Apres exposition a des electrons de 15 MeV, la proliferation des grandes cellules est plus active, suivant les courbes d'atrophie du thymus en fonction du temps. D'apres les resultats ci-dessus, il semblerait que le pouvoir de regeneration depende de l'importance des lesions subies par les cellules primitives; pour une dose donnee, ces lesions semblent plus marquees apres exposition aux rayons X qu'apres exposition aux electrons.

Two hundred health care workers in England and Wales were vaccinated with the Lister/Elstree strain of the vaccinia virus, and completed health diaries for 21 days or until the lesion had scabbed over. Pain and temperature were measured daily, and all other symptoms recorded freehand by the vaccinee. One hundred and forty two (71%) vaccinees reported pain, of which 25% considered it to be moderate or severe; 32 vaccinees (16%) recorded a temperature of >37.7 degrees C, two of which exceeded 39 degrees C. Other, mainly trivial, adverse events were common; itch was reported in 72%, erythema in 27%, axillary pain or lymphadenopathy in 38%, malaise or flu-like symptoms in 40% and headache in 23%. The incidences of minor adverse events were lower in re-vaccinees, compared with naïve vaccine recipients, significantly so in the case of erythema and general malaise (p=0.001 and 0.006, respectively), perhaps reflecting pre-existing immunity. Major adverse events occurred in two vaccinees (hospital admission, one with cellulitis and one with headache and possible encephalitis), and a further five were treated with antibiotics for local cellulitis. This is the first study to report results derived from active follow-up by diaries in recipients of the Lister/Elstree strain of vaccinia, and to document reductions in trivial adverse events in re-vaccinees.

The theory of the statistical fluctuations in a pile is extended to the space dependent case, and gives the fluctuations of the number of neutrons in a cell of the core or reflector of the pile. This number changes through elementary processes occurring at random, which are, capture, source, fission and scattering. Of all these processes, fission is the only one which changes more than one neutron at a time and so is responsible of the deviation of the fluctuations from a Poisson law. The importance of this deviation depends on the dimensions of the cell compared to the slowing down length. When the dimensions are small, the fluctuations close to a Poisson law. (author) [French] La theorie des fluctuations statistiques est etendue au cas local et donne les fluctuations du nombre de neutrons dans une cellule situee dans le coeur ou le reflecteur de la pile. Ce nombre evolue au cours du temps sous l'influence de phenomenes aleatoires qui sont la capture, la diffusion, les sources et les neutrons secondaires de fission. L'emission simultanee de plusieurs neutrons distingue ce phenomene des precedents qui n'affectent qu'un neutron individuellement. L'importance de ce phenomene sur la loi de fluctuation depend des dimensions de la cellule par rapport a la longueur de ralentissement. Quand ces dimensions sont petites, le caractere particulier de ce phenomene disparait. (auteur)

Breast cancer-related lymphedema often causes cellulitis and is one of the most common complications after breast cancer surgery. Streptococci are the major pathogens underlying such cellulitis. Among the streptococci, the importance of the Lancefield groups C and G is underappreciated; most cases involve Streptococcus dysgalactiae subspecies equisimilis. Despite having a relatively weak toxicity compared with group A streptococci, Streptococcus dysgalactiae subspecies equisimilis is associated with a mortality rate that is as high as that of group A streptococci in cases of invasive infection because Streptococcus dysgalactiae subspecies equisimilis mainly affects elderly individuals who already have various comorbidities. An 83-year-old Japanese woman with breast cancer-related lymphedema in her left upper limb was referred to our hospital with high fever and acute pain with erythema in her left arm. She showed septic shock with disseminated intravascular coagulation. Blood culture showed positive results for Streptococcus dysgalactiae subspecies equisimilis, confirming a diagnosis of streptococcal toxic-shock syndrome. She survived after successful intensive care. To the best of our knowledge, this case represents the first report of Streptococcus dysgalactiae subspecies equisimilis-induced streptococcal toxic-shock syndrome in a patient with breast cancer-related lymphedema. Breast cancer-related lymphedema is a common problem, and we must pay attention to invasive streptococcal soft tissue infections, particularly in elderly patients with chronic disease.

2008-03-01

Full Text Available This paper aims to evaluate the recent and numerous applications of ultrasonography in the differential diagnosis of conditions that affect the popliteal fossa and lower limbs, resulting in calf pain. Popliteal cysts and their ruptures, aneurysms, hematomas, cellulitis, abscesses, soft tissue tumors and other fluid collections are easily identified by this technique. Moreover, post-trauma and inflammatory conditions affecting muscles and tendons, muscle necrosis, deep venous thrombosis and superficial thrombophlebitis are very well demonstrated by the ultrasonographic screening.

Full Text Available Catheter insertion for intravenous hyperalimentation is a commonly and widely used clinical technique. When compared with the incidence of complications associated with insertions into the internal jugular vein or the subclavian vein, complications associated with insertions into the femoral vein are less frequent. In this paper, we describe a very rare complication of femoral vein catheter insertion—namely, catheter displacement into the inferior epigastric vein.

Polymer photovoltaic cells; Etude et realisation de cellules photovoltaiques en polymere

Energy Technology Data Exchange (ETDEWEB)

Sicot, L.

1999-09-29

We study organic photovoltaic cells based on a semiconducting polymer. The first photovoltaic cells we realize are Schottky cells. Their structure are ITO/Polymeric film/Au. Metallic electrode is made of aluminium or gold. The organic layer is made of pure poly(3-butyl-thiophene) or of a blend of the polymer and a dye, the 1,3-bis(di-cyano-methylidene)-2-(4-dibutyl-amino-benzylidene)indane. We study the influence of the nature of the electrode on the conversion efficiency. We also study the variations of the photovoltaic parameters as functions of the thickness of the polymeric film and of the doping ratio of the dye. The performances of this kind of cells depends on the interface between the organic layer and the ITO. Its morphology, particularly its rugosity, and its electrical properties are not easy to control. By depositing a layer of a derivative of perylene on the ITO, we move the photo-generation zone to the interface between the two organic films. The efficiency of this p-n cell is higher than the one measured with the Schottky cell. Nevertheless, we have observed a decrease of the performances of our cells due to the degradation of the dye and the polymer when they are illuminated at high intensity of light during a long time.

Yao-Hung Tsai

2017-10-01

Conclusions: Victims of venomous snakebites should be admitted for close monitoring of secondary wound infections. The risk factors of developing necrotizing fasciitis from cellulitis following snakebites were associated with chronic underlying diseases and leukocytosis (total white blood-cell counts ≥10000 cells/mm3 and ≥80% of segmented leukocyte forms. Physicians should be alert to a worsening wound condition after a snakebite, and surgical interventions should be performed for established necrotizing fasciitis with the empirical use of third-generation cephalosporins plus other regimens.

Rhino-orbital mucormycosis is the most frequently fatal fungal infection commonly occurring in patients with poorly controlled diabetes mellitus and those who are immunocompromised, and requires prompt treatment. We describe a case of rhino-orbital mucormycosis with orbital cellulitis and paranasal sinusitis, as seen on initial MR images, which on follow-up images had evolved to orbitofacial infarction. MR imaging was useful for the demonstration of orbitofacial infarction, seen as areas of lack of enhancement and thus suggesting vascular involvement by mucor hyphae. (author)

Comets As Objects of High Energy Astrophysics

2000-10-01

Strong soft X-ray emission from comet Hyakutake C/1996 B2 was discovered with ROSAT in March 27, 1996 (Lisse et al. 1996, Science 274, 205-209) and the results of a theoretical approach (Ibadov 1990, Icarus 86, 283-288) served as a motive for that observations (Dennerl, Lisse and Truemper 1998, Private Communications). It is now well established that comets emit EUV and X-rays regularly (Dennerl, Englhauser and Truemper 1997, Science 277, 1625-1630; Dennerl 1998, Proc. 16th Int. Conf. Atomic Physics, Windsor, Ontario, Canada). To explain this phenomenon different theoretical models were proposed (Krasnopolsky 1997, Icarus 128, 365-385; Ibadov 1998, Proc. First XMM Workshop, Noordwijk, The Netherlands, and references therein). In the paper the problem of identifying X-ray generation mechanisms in comets will be considered.

A total of 337 Kaingang and Guarani Indians from two localities were studied in relation to 18 protein genetic loci. In one of the localities, members of these two groups live side by side but show little genetic similarity, emphasizing the influence of cultural factors in the mating behavior of human groups. Integrating the present results with previous ones, it was verified that the genetic relationships among six Kaingang populations do not follow the pattern expected from their geographical distribution. Comparisons made with three other Ge˜-speaking tribes indicate that the Kaingang did not separate well from them. Most (96%) of the variability in the six polymorphic systems considered occur at the intrapopulational level. Am. J. Hum. Biol. 9:505-512, 1997. © 1997 Wiley-Liss, Inc.

To investigate the diagnostic value of contrast-enhanced computed tomography (CT) for the prediction of deep neck abscesses in different deep neck spaces and to evaluate the false-positive results. We retrospectively analysed the clinical charts, CT examinations, surgical findings, bacteriology, pathological examinations and complications of hospitalised patients with a diagnosis of deep neck abscess from 2004 to 2010. The positive predictive values (PPV) for the prediction of abscesses by CT scan in different deep neck spaces were calculated individually on the basis of surgical findings. A total of 162 patients were included in this study. All patients received both intravenous antibiotics and surgical drainage. The parapharyngeal space was the most commonly involved space. The overall PPV for the prediction of deep neck abscess with contrast-enhanced CT was 79.6%. The PPV was 91.3% when more than one deep neck space was involved but only 50.0% in patients with isolated retropharyngeal abscesses. In the false-positive group, cellulitis was the most common final result, followed by cystic degeneration of cervical metastases. Five specimens taken intra-operatively revealed malignancy and four of these were not infected. There are some limitations affecting the differentiation of abscesses and cellulitis, particularly in the retropharyngeal space. A central necrotic cervical metastatic lymph node may sometimes also mimic a simple pyogenic deep neck abscess on both clinical pictures and CT images. Routine biopsy of the tissue must be performed during surgical drainage.

Les biofilms bactériens : leur importance en santé animale et en santé publique

Tremblay, Yannick D.N.; Hathroubi, Skander; Jacques, Mario

2014-01-01

Résumé Les biofilms bactériens sont des amas structurés de cellules bactériennes enrobés d’une matrice polymérique et attachés à une surface. Le biofilm protège les bactéries et leur permet de survivre dans des conditions environnementales hostiles. Les bactéries du biofilm peuvent résister à la réponse immunitaire de l’hôte et sont beaucoup plus résistantes aux antibiotiques et aux désinfectants que les cellules bactériennes planctoniques. La capacité de former un biofilm est maintenant reconnue comme une caractéristique propre à plusieurs microorganismes. La présence de biofilms lors d’infections demande donc de nouvelles méthodes de prévention, de diagnostic et de traitement. De même, la présence de biofilms sur des surfaces retrouvées à la ferme, à l’abattoir ou à l’usine de transformation affectera l’efficacité du protocole de désinfection. De façon surprenante, la formation de biofilms chez les bactéries pathogènes des animaux et les bactéries zoonotiques est un sujet relativement peu étudié. Ce bref compte rendu a pour objectif de sensibiliser les intervenants en santé animale à l’importance des biofilms. PMID:24688172

Assessment of Quadrivalent Human Papillomavirus Vaccine Safety Using the Self-Controlled Tree-Temporal Scan Statistic Signal-Detection Method in the Sentinel System.

The self-controlled tree-temporal scan statistic-a new signal-detection method-can evaluate whether any of a wide variety of health outcomes are temporally associated with receipt of a specific vaccine, while adjusting for multiple testing. Neither health outcomes nor postvaccination potential periods of increased risk need be prespecified. Using US medical claims data in the Food and Drug Administration's Sentinel system, we employed the method to evaluate adverse events occurring after receipt of quadrivalent human papillomavirus vaccine (4vHPV). Incident outcomes recorded in emergency department or inpatient settings within 56 days after first doses of 4vHPV received by 9- through 26.9-year-olds in 2006-2014 were identified using International Classification of Diseases, Ninth Revision, diagnosis codes and analyzed by pairing the new method with a standard hierarchical classification of diagnoses. On scanning diagnoses of 1.9 million 4vHPV recipients, 2 statistically significant categories of adverse events were found: cellulitis on days 2-3 after vaccination and "other complications of surgical and medical procedures" on days 1-3 after vaccination. Cellulitis is a known adverse event. Clinically informed investigation of electronic claims records of the patients with "other complications" did not suggest any previously unknown vaccine safety problem. Considering that thousands of potential short-term adverse events and hundreds of potential risk intervals were evaluated, these findings add significantly to the growing safety record of 4vHPV.

The aim of this study was to assess the incidence and susceptibility to antibacterial agents of anaerobic strains in 118 patients with head and neck abscesses (31) and cellulitis (87). Odontogenic infection was the most common identified source, occurring in 73 (77.7%) of 94 patients. The incidence of anaerobes in abscesses and cellulitis was 71 and 75.9%, respectively, and that in patients before (31 patients) and after (87) the start of empirical treatment was 80.6 and 72.4%, respectively. The detection rates of anaerobes in patients with odontogenic and other sources of infection were 82.2 and 71.4%, respectively. In total, 174 anaerobic strains were found. The predominant bacteria were Prevotella (49 strains), Fusobacterium species (22), Actinomyces spp. (21), anaerobic cocci (20) and Eubacterium spp. (18). Bacteroides fragilis strains were isolated from 7 (5.9%) specimens. The detection rate of Fusobacterium strains from non-treated patients (32.2%) was higher than that from treated patients (13.8%). Resistance rates to clindamycin and metronidazole of Gram-negative anaerobes were 5.4 and 2.5%, respectively, and those of Gram-positive species were 4.5 and 58.3%, respectively. One Prevotella strain was intermediately susceptible to ampicillin/sulbactam. In conclusion, the start of empirical treatment could influence the frequency or rate of isolation of Fusobacterium species. The involvement of the Bacteroides fragilis group in some head and neck infections should be considered.

Full Text Available Necrotizing fasciitis is a rapidly progressive life threatening bacterial infection of the skin, the subcutaneous tissue, and the fascia. We present a case of necrotizing fasciitis involving the nose complicated by cavernous sinus thrombosis. Few cases of septic cavernous sinus thrombosis have been reported to be caused by cellulitis of the face but necrotizing fasciitis of the nose is rare. It is very important to recognize the early signs of cavernous thrombosis. Treatment for septic cavernous sinus thrombosis is controversial but early use of empirical antibiotics is imperative.

Full Text Available Shewanella putrefaciens rarely causes human infection. These are mostly found in environment and food stuffs. Shewanella are often found in mixed culture. It has been implicated in cellulitis, otitis media, and septicemia. It may be found in respiratory tract, urine, feces, and pleural fluid. There is no definite guideline for therapeutic option. In general, these are susceptible to various antimicrobial agents but are often resistant to penicillin and cephalothin. We report a rare case of bacteremia by S. putrefaciens in a patient of head injury with polytrauma after a road traffic accident.

Full Text Available Ludwig's angina is potentially lethal, rapidly spreading cellulitis of the floor of mouth and neck. The anticipated difficult airway becomes even more challenging when it occurs in children. In children, the larynx is positioned relatively higher in the neck, and one does not have the option for blind nasal intubation or awake fiberoptic, which otherwise is the technique of choice in adult patients. We present the clinical course of 16 children and highlight various problems encountered during the anesthetic management of six children who required emergency surgical drainage under general anesthesia.

ènes entre plantes et micro-organismes. Parmi les trois mécanismes précédemment cités, seule la transformation génétique est en mesure d’assurer le transfert d’ADN entre plantes et bactéries [4]. Celle-ci se caractérise par l’acquisition d’ADN extracellulaire par une cellule bactérienne en état de compétence. En conditions naturelles, la réalisation d’un tel processus requiert donc successivement la libération d’ADN par la plante et la persistance de ces molécules dans un environnement hostile jusqu’au contact avec des cellules bactériennes non seulement génétiquement adaptées pour la transformation mais physiologiquement dans un stade de compétence. Enfin, l’ADN ayant pénétré une cellule bactérienne ne s’y maintiendra que si les séquences qu’il porte et les mécanismes de la cellule hôte lui permettent de s’intégrer dans le génome ou, éventuellement, de se répliquer de façon autonome.

1996-01-01

The present study tested whether various sociodemographic, anthropometric, behavioral, and medical/physiological factors act in a direct or indirect manner on the risk of prematurity using path analysis on a sample of Israeli births. The path model shows that medical complications, primarily toxemia, chorioammionitis, and a previous low birth weight delivery directly and significantly act on the risk of prematurity as do low maternal pregnancy weight gain and ethnicity. Other medical complications, including chronic hypertension, preclampsia, and placental abruption, although significantly correlated with prematurity, act indirectly on prematurity through toxemia.

Comparative myology of the unicornfishes, Naso (Acanthuridae, Percomorpha), with implications for phylogenetic analysis.

Science.gov (United States)

Borden, W Calvin

1999-02-01

Striated muscles of 15 species of unicornfishes (Naso, Acanthuridae) are described in detail. Of 93 muscles dissected, only five demonstrate intrageneric variation, providing only ten characters suitable for phylogenetic analysis. Thus, myology appears to be highly conservative at the species level and has been so for approximately 50-55 million years in this particular group of fishes. Furthermore, myology is static relative to osteology in Naso and at any taxonomic rank within fishes, implying osteology provides a larger but not necessarily more valuable data source for systematic studies. Although important for their epistomological value, these descriptions provide a basis for further studies ranging from functional, comparative, and systematic analyses, ultimately with the potential to address questions of historical ecology (i.e., speciation, adaptation, coevolution) within Naso.

Anatomy and histochemistry of spread-wing posture in birds. I. Wing drying posture in the double-crested cormorant, Phalacrocorax auritus.

Science.gov (United States)

Meyers, Ron A

1997-07-01

Spread-wing postures of birds often have been studied with respect to the function of behavior, but ignored with regard to the mechanism by which the birds accomplish posture. The double-crested cormorant, Phalacrocorax auritus, was used as a model for this study of spread-wing posture. Those muscles capable of positioning and maintaining the wing in extension and protraction were assayed histochemically for the presence of slow (postural) muscle fibers. Within the forelimb of Phalacrocorax, Mm. coracobrachialis cranialis, pectoralis thoracicus (cranial portion), deltoideus minor, triceps scapularis, and extensor metacarpi radialis pars dorsalis and ventralis were found to contain populations of slow-twitch or slow-tonic muscle fibers. These slow fibers in the above muscles are considered to function during spread-wing posture in this species. J Morphol 233:67-76, 1997. © 1997 Wiley-Liss, Inc. Copyright © 1997 Wiley-Liss, Inc.

We have tested this model for the fourfold increase in activity since mid-1962 and have found it to predict accurately the present distribution of caesium-137 radioactivity between individual members of the sample population. (author) [French] Les faibles concentrations de radioactivite artificielle dans l'organisme risquent d'avoir des effets nuisibles dans une population surtout pour les individus chez qui cette concentration atteint une valeur plusieurs fois superieure a la moyenne. On ne peut estimer valablement les dangers dus aux retombees radioactives que si l'on connait la loi de frequence de la radioactivite dans la population. Les tentatives faites pour determiner la forme de la courbe de frequence a partir des donnees de Kulp sur la concentration du strontium 90 dans les tissus osseux d'enfants n'ont abouti qu'a des resultats limites en laison de la petite taille de'l'echantillon et de l'absence d'equilibre entre le strontium 90 et le calcium dans ces tissus. Pour y remedier, les auteurs ont dose le cesium 137 d'environ 900 echantillons de tissus musculaires. Ces echantillons avaient ete preleves a l'occasion d'autopsies pratiquees entre janvier 1959 et aout 1963. En utilisant le cesium 137 comme indicateur des produits de fission, on s'assure que tous les individus du'groupe, quel que fut leur age, etaient essentiellement en equilibre avec la radioactivite ambiante au moment de leur deces. L'enquete a ete faite pendant la periode correspondant a la premiere interruption des essais d'engins nucleaires et a la reprise en grand de ces essais a l'automne 1961. La teneur moyenne en cesium 137 des echantillons de tissus musculaires est restee relativement constante durant toute l'annee 1959, puis a diminue d'un facteur de deux en 1960 et est demeuree relativement stable jusqu'au debut de l'ete 1962.

This research thesis reports a radiobiological study of Dianthus periclinal chimeras performed by submitting plants and plant cuttings at different physiological stages to cobalt-60 gamma irradiation under different dose conditions and rates. The effects of these treatments are studied while growing the so-processed plants and by microscopic examination of sections of irradiated meristems [French] Une etude radiobiologique de chimeres periclinales d'oeillet est effectuee en soumettant au rayonnement gamma du cobalt 60, sous differentes conditions de doses et debits de dose, des plantes entieres et des boutures a des stades physiologiques differents. Les effets des traitements sont observes au cours de la culture des plantes traitees et par l'examen microscopique de coupes des meristemes irradies. La destruction de cellules meristematiques, dans des proportions variables avec les modalites d'irradiation, provoque des modifications de structure des chimeres dont les plus frequentes sont la formation de tiges genetiquement homogenes a partir des differents genotypes existants dans la plante irradiee. Le traitement aux radiations ionisantes constitue donc une methode pratique de detection des chimeres periclinales qui, a l'image de ce qui se passe pour l'oeillet, sont tres repandues chez les plantes cultivees a propagation vegetative. Mais, comme il existe generalement plus de deux ensembles cellulaires meristematiques independants, cette methode ne permet pas, a elle seule, de definir la repartition des differents genotypes dans ces ensembles; elle doit alors etre completee par des etudes genetiques ou des marquages cellulaires tels que des mutations chlorophylliennes ou de genomes. Ainsi la structure de deux varietes d'oeillet a fleurs oranges, qui produisent, apres irradiation, des fleurs rouges et des fleurs jaunes, a ete determinee grace a l'obtention, par traitement a la colchicine, de cytochimeres 4 - 2 - 2 et 2 - 4 - 4.

The purpose of this study was to report the MRI findings that can be encountered in successfully treated bacterial septic arthritis. The study included 12 patients (8 male and 4 female; mean age 38 years, range 9-85) with 13 proven cases of bacterial septic arthritis. The joints involved were hip (n = 3), knee (n = 3), shoulder (n = 2), sacroiliac (n = 2), ankle (n = 1), wrist (n = 1), and elbow (n = 1). MRI examinations following surgical debridement and at initiation of antibiotic therapy and after successful treatment were compared for changes in effusion, synovium, bone, and periarticular soft tissues. Imaging findings were correlated with microbiological and clinical findings. Joint effusions were present in all joints at baseline and regressed significantly at follow-up MRI (p = 0.001). Abscesses were present in 5 cases (38 %), and their sizes decreased significantly at follow-up (p = 0.001). Synovial enhancement and thickening were observed in all joints at both baseline and follow-up MRI. Myositis/cellulitis was present in 10 cases (77 %) at baseline and in 8 cases (62 %) at follow-up MRI. Bone marrow edema was present in 10 joints (77 %) at baseline and persisted in 8 joints (62 %). Bone erosions were found in 8 joints (62 %) and persisted at follow-up MRI in all cases. The sizes of joint effusions and abscesses appear to be the factors with the most potential for monitoring therapy for septic arthritis, since both decreased significantly following successful treatment. Synovial thickening and enhancement, periarticular myositis/cellulitis, and bone marrow edema can persist even after resolution of the infection. (orig.)

Lymphedema typically affects a whole limb. Rarely, lymphedema can present as a circumscribed plaque or an isolated skin tumor. To describe the clinical and pathologic characteristics and etiologic factors of localized lymphedema. Case-control study of skin biopsy and excision specimens histologically diagnosed with lymphedema and presenting as a localized skin tumor identified during a 4-year period. We identified 24 cases of localized lymphedema presenting as solitary large polyps (11), solid or papillomatous plaques (7), pendulous swellings (4), or tumors mimicking sarcoma (2). Patients were 18 females and 6 males with a mean age of 41 years (range 16-74). Anogenital involvement was most frequent (75%)--mostly vulva (58%), followed by eyelid (13%), thigh (8%) and breast (4%). Causative factors included injury due to trauma, surgery or childbirth (54%), chronic inflammatory disease (rosacea, Crohn's disease) (8%), and bacterial cellulitis (12%). Eighty-five percent of these patients were either overweight (50%) or obese (35%). Compared with a series of 80 patients with diffuse lymphedema, localized lymphedema patients were significantly younger (41 vs. 62 years old, p = 0.0001), had no history of cancer treatment (0% vs. 18%, p = 0.03), and had an injury to the affected site (54% vs. 6%, p = 0.0001). Histologically, all cases exhibited dermal edema, fibroplasia, dilated lymphatic vessels, uniformly distributed stromal cells and varying degrees of papillated epidermal hyperplasia, inflammatory infiltrates and hyperkeratosis. Tumor size significantly and positively correlated with history of cellulitis, obesity, dense inflammatory infiltrates containing abundant plasma cells, and lymphoid follicles (p elephantiasis.

Safety and tolerability of denosumab for the treatment of postmenopausal osteoporosis

Lewiecki EM

Full Text Available E Michael LewieckiNew Mexico Clinical Research & Osteoporosis Center, Albuquerque, New Mexico, USAAbstract: Denosumab is a fully human monoclonal antibody to receptor activator of nuclear factor kappa-B ligand (RANKL, a cytokine member of the tumor necrosis factor family that is the principal regulator of osteoclastic bone resorption. Postmenopausal osteoporosis (PMO is a systemic skeletal disease associated with high levels of RANKL, resulting in a high rate of bone remodeling and an imbalance of bone resorption over bone formation. By inhibiting RANKL in women with PMO, denosumab reduces the rate of bone remodeling, thereby increasing bone mineral density, improving bone strength, and reducing the risk of fractures. In clinical trials of women with osteoporosis and low bone mineral density, denosumab has been well tolerated, with overall rates of adverse events and serious adverse events in women treated with denosumab similar to those receiving placebo. In the largest clinical trial of denosumab for the treatment of women with PMO, there was a significantly greater incidence of cellulitis reported as a serious adverse event, with no difference in the overall incidence of cellulitis, and a significantly lower incidence of the serious adverse event of concussions with denosumab compared with placebo. The evidence supports a favorable balance of benefits versus risks of denosumab for the treatment of PMO. Assessments of the long-term safety of denosumab are ongoing. Denosumab 60 mg subcutaneously every 6 months is an approved treatment for women with PMO who are at high risk for fracture.Keywords: denosumab, osteoporosis, safety, risk, benefit, FDA

CASE DESCRIPTION A 1-year-old reticulated python (Python reticulatus) was evaluated because of a 2-week history of wheezing and hissing. CLINICAL FINDINGS Rostral facial cellulitis and deep gingival pockets associated with missing rostral maxillary teeth were evident. Tissues of the nares were swollen, resulting in an audible wheeze during respiration. Multiple scars and superficial facial wounds attributed to biting by live prey were apparent. Radiographic examination revealed bilateral, focal, rostral maxillary osteomyelitis. TREATMENT AND OUTCOME Wound irrigation, antimicrobials, and anti-inflammatory drug treatment resulted in reduced cellulitis. A 3-week regimen that included empirical antimicrobial treatment and improved husbandry resulted in resolution of the respiratory sounds and partial healing of bite wounds, but radiographic evaluation revealed progressive maxillary osteomyelitis. Microbial culture of blood yielded scant gram-positive cocci and Bacillus spp, which were suspected sample contaminants. Bilateral partial maxillectomies were performed; microbial culture and histologic examination of resected bone confirmed osteomyelitis with gram-positive cocci. Treatment with trimethoprim-sulfamethoxazole was initiated on the basis of microbial susceptibility tests. Four months later, follow-up radiography revealed premaxillary osteomyelitis; surgery was declined, and treatment with trimethoprim-sulfamethoxazole was reinstituted. Eight months after surgery, the patient was reevaluated because of recurrent clinical signs; premaxillectomy was performed, and treatment with trimethoprim-sulfamethoxazole was prescribed on the basis of microbial culture of bone and microbial susceptibility testing. Resolution of osteomyelitis was confirmed by CT 11 months after the initial surgery. CONCLUSIONS AND CLINICAL RELEVANCE Focal maxillectomies and premaxillectomy were successfully performed in a large python. Surgical management and appropriate antimicrobial treatment

We have to investigate the equilibrium regime that appears between a hot cathode and the electronic cloud that is confined around the cathode by a magnetic field parallel to its axis. The densities being high enough to involve the effect of space charge. The challenge of the magnetron theory is to face 2 issues: first the structure of the electronic cloud in a diode submitted to a magnetic field and secondly the oscillations that are likely to appear in this cloud. In this work we have made 2 attempts to clarify the situation, we have extended the classical theory of the static charge of space through a study of its oscillation modes on one hand and on the other hand we have tackled the issue of the structure of the electronic cloud with the tool of statistics. This document is divided into 2 chapters. In the first chapter we present a static study of the magnetron in which we take a statistical approach deliberately. We give answers to the issue of the thermodynamical equilibrium of the electronic cloud and we have found a mode very close to the Brillouin mode. The statistical approach has made us discuss the boundary conditions on the cathode, it means the coupling between the cathode and the electronic cloud. In the second chapter we present the theoretical study of the oscillations in a magnetron operating in the Brillouin mode. The resonances that appear in experimental data stay difficult to explain.

Effects of religion, economics, and geography on genetic structure of Fogo Island, Newfoundland.

The population structure of Fogo Island, Newfoundland is described using geography, religious affiliation, economic factors (such as the presence of a fish-packing plant), and genetic markers. Five different analytic methods, R-matrix analysis, r ii VS. mean per locus heterozygosity, predicted kinship (ϕ), mean first passage time, and Mantel matrix comparisons, were applied to the Fogo Island genetic and demographic data. The results suggest that geography plays a role on Fogo Island in the distribution of genes, while religion, ethnicity, and economic factors play less significant roles. The communities with fish-packing plants and tourism serve as migratory "sinks" for Fogo islanders seeking employment. Reproductively, the most isolated village on Fogo Island is Tilting, and this is reflected in its genetic uniqueness, initially caused by Irish settlement and subsequently the action of stochastic processes. © 1995 Wiley-Liss, Inc.

The purpose of creating the virtual reality (VR) simulator is to facilitate and supplement the training opportunities provided to orthopedic residents. The use of VR simulators has increased rapidly in the field of medical surgery for training purposes. This paper discusses the creation of the virtual surgical environment (VSE) for training residents in an orthopedic surgical process called less invasive stabilization system (LISS) surgery which is used to address fractures of the femur. The overall methodology included first obtaining an understanding of the LISS plating process through interactions with expert orthopedic surgeons and developing the information centric models. The information centric models provided a structured basis to design and build the simulator. Subsequently, the haptic-based simulator was built. Finally, the learning assessments were conducted in a medical school. The results from the learning assessments confirm the effectiveness of the VSE for teaching medical residents and students. The scope of the assessment was to ensure (1) the correctness and (2) the usefulness of the VSE. Out of 37 residents/students who participated in the test, 32 showed improvements in their understanding of the LISS plating surgical process. A majority of participants were satisfied with the use of teaching Avatars and haptic technology. A paired t test was conducted to test the statistical significance of the assessment data which showed that the data were statistically significant. This paper demonstrates the usefulness of adopting information centric modeling approach in the design and development of the simulator. The assessment results underscore the potential of using VR-based simulators in medical education especially in orthopedic surgery.

While on our general inpatient rehabilitation floor, a 58-year-old man with no hematologic or dermatologic history developed an erythematous patch on his medial ankle that turned more purpuric, with a slight orange tint, and was associated with mild pruritus. The diagnosis of exercise-induced vasculitis was made after initially being mistaken for cellulitis. This common exanthem is often misdiagnosed. Due to its association with exercise, the physiatrist should be aware of its presence in both the inpatient and outpatient settings.

2014-01-01

Full Text Available We present the unusual case of a large complex odontoma erupting in the maxilla. Odontomas are benign developmental tumours of odontogenic origin. They are characterized by slow growth and nonaggressive behaviour. Complex odontomas, which erupt, are rare. They are usually asymptomatic and are identified on routine radiograph but may present with erosion into the oral cavity with subsequent cellulitis and facial asymmetry. This present paper describes the presentation and management of an erupting complex odontoma, occupying the maxillary sinus with extension to the infraorbital rim. We also discuss various surgical approaches used to access this anatomic area.

Scheinfeld, Noah S

2004-01-01

Obesity is associated with a number of dermatoses. It affects cutaneous sensation, temperature regulation, foot shape, and vasculature. Acanthosis nigricans is the most common dermatological manifestation of obesity. Skin tags are more commonly associated with diabetes than with obesity. Obesity increases the incidence of cutaneous infections that include: candidiasis, intertigo, candida folliculitis, furunculosis, erythrasma, tinea cruris, and folliculitis. Less common infections include cellulitis, necrotizing fasciitis, and gas gangrene. Leg ulcerations, lymphedema, plantar hyperkeratosis, and striae are more common with obesity. Hormonal abnormalities and genetic syndromes (Prader-Willi) are related to obesity and its dermatoses; however, cellulite is not related to obesity.

Full Text Available Odontogenic keratocyst is a cyst of dental lamina origin with a high recurrence rate and well defined histologic criteria. Radiographically, odontogenic keratocyst presents as a unilocular or multilocular radiolucency of the jaws. Its capacity for aggressive growth and recurrence even after many years makes it an entity of special interest. Recently, neoplastic transformations have also been reported. They must therefore be distinguished from other cysts and tumors of the jaws. We report a case of fortuitous bilobular radiolucency in the left ascending ramus of a patient, who reported with a clinical presentation of submandibular space cellulitis.

Full Text Available Granulomatous disorders comprise a large family sharing the common histological denominator of granuloma formation. Collagenolytic or necrobiotic granuloma is one in which a granulomatous infiltrate develops around a central area of altered collagen and elastic fibers. The altered fibers exhibit new staining patterns, becoming either more basophilic which gives blue appearance (“blue granuloma” or eosinophilic giving red appearance (“red granuloma”. Conditions which exhibit blue granuloma include granuloma annulare, Wegener's granulomatosis, and rheumatoid vasculitis, whereas red granulomas include necrobiosis lipoidica, necrobiosis xanthogranuloma, rheumatoid nodules, Churg-Strauss syndrome, and eosinophilic cellulitis (Well's syndrome.

Lusseyran, Francois

1990-12-13

This research thesis reports the study and description of the structure of a slug flow regime in a co-current vertical cylindrical duct, and the characterization and prediction of its transition towards a slug-churn (de-structured) regime. Flow physical mechanisms highlighted by the measurement of two important dynamics variables (wall friction and thickness of liquid films) are related to hypotheses of cellular models. The author first proposes an overview of slug flow regimes: theoretical steady and one-dimensional analysis, mass assessment equations of cellular models, application to the assessment of the flow rate and of the thickness of the film surrounding the gas slug. In the second part, the author addresses the slug flow regime transition towards the slug-churn regime: assessment of the evolution of flow dynamic properties, use of average wall friction analysis to obtain a relevant transition criterion. The third part presents experimental conditions, and measurement methods: conductometry for thickness measurement, polarography for wall friction measurement, and gas phase detection by using an optic barrier or optic fibres [French] Les ecoulements gaz-liquide en conduite verticale presentent quatre configurations ou regimes d'ecoulement. Ce travail porte sur le regime a poches et sur la transition vers la configuration qui lui succede: le regime destructure (churn flow). Les mesures sont effectuees a 200D du point d'injection du gaz, dans une conduite de 12.2 mm de diametre et pour le couple de fluides eau-azote. Les deux principales grandeurs mesurees en fonction des flux d'entree sont: le frottement parietal instantane (methode electrochimique) et l'epaisseur de film instantanee (methode conductimetrique). Une detection optique simultanee de la presence des phases permet un traitement conditionnel de la base de donnees.

Sex hormones play an important role in the control of glucose metabolism and insulin. Decreased glucose tolerance observed at the end of pregnancy in most cases remains within normal limits. Pregnancy has an important effect on the islets of Langerhans and on the growth of beta cellules. At the end of pregnancy, assimilation of glucose and triglycerides by maternal tissues is slowed and transfer to the fetus is favored. Hyperinsulinism persists but insulin resistance at the level of maternal tissue becomes very strong and the number of receptors declines. This late pregnancy insulin resistance has not been satisfactorily explained. The declining number of receptors may be a mechanism, or the "antiinsulin" pregnancy hormones which includes estrogens and progesterone may play a major role. Although other mechanisms have been proposed to explain the antiinsulin effect, the role of sex hormones and especially of progesterone (and synthetic progestins used in contraception) appears crucial. The presence of estrogen and progesterone receptors in the beta cellules of the islets of Langerhans suggests a direct effect of these hormones on the cellules. Estrogens however work by other mechanisms than insulin secretion. Experimental evidence indicates that during pregnancy, progesterone increases insulin release while human placental lactogen stimulates hyperplasia of the islets. The progestins derived from progesterone used in contraception have a parallel action. A slight elevation of blood sugar and insulinemia have been observed in oral contraceptive (OC) users. Only 3-5% of OC users develop true hyperglycemia. The changes are usually transitory and disappear on termination of OC use except in the small number of women predisposed to diabetes. The decreased glucose tolerance of OC users differs from true diabetes. Combined OCs favor vascular accidents and myocardial infarct in insulin-dependent diabetics. The mechanisms involved include deteriorating control of diabetes
