The Hot Orbit: Orbital Cellulitis  

PubMed Central

Orbital cellulitis is an uncommon condition previously associated with severe complications. If untreated, orbital cellulitis can be potentially sight and life threatening. It can affect both adults and children but has a greater tendency to occur in the pediatric age group. The infection most commonly originates from sinuses, eyelids or face, retained foreign bodies, or distant soources by hematogenous spread. It is characterized by eyelid edema, erythema, chemosis, proptosis, blurred vision, fever, headache, and double vision. A history of upper respiratory tract infection prior to the onset is very common especially in children. In the era prior to antibiotics, vision loss from orbital cellulitis was a dreaded complication. Currently, imaging studies for detection of orbital abcess, the use of antibiotics and early drainage have mitigated visual morbidity significantly. The purpose of this review is to describe current investigative strategies and management options in the treatment of orbital cellulitis, establish their effectiveness and possible complications due to late intervention.

Breast cellulitis after conservative surgery and radiotherapy  

SciTech Connect

Cellulitis is a previously unreported complication of conservative surgery and radiation therapy for early stage breast cancer. Patients who presented with breast cellulitis after conservative therapy are described. Eleven patients that developed cellulitis of the breast over a 38-month period of observation are the subject of this report. Clinical characteristics of patients with cellulitis and their treatment and outcome are reported. Potential patient and treatment-related correlates for the development of cellulitis are analyzed. The risk of cellulitis persists years after initial breast cancer therapy. The clinical course of the patients was variable: some patients required aggressive, long-duration antibiotic therapy, while others had rapid resolution with antibiotics. Three patients suffered from multiple episodes of cellulitis. Patients with breast cancer treated with conservative surgery and radiotherapy are at risk for breast cellulitis. Systematic characterization of cases of cellulitis may provide insight into diagnosis, prevention, and more effective therapy for this uncommon complication. 15 refs., 1 fig., 2 tabs.

In general, skin squamous cell carcinoma (SCC) presents as papules or plaques with erythematous or pigmented appearance that may ulcerate the skin. Cellulitis caused by metastatic deposit from a known primary skin SCC has been reported once.1 We describe a patient who presented with cellulitis on the face that did not respond well to full course of antibiotics treatment, and turned out to be a newly diagnosed SCC after biopsy. Other differential diagnoses, such as malignancy, should be suspected in all unusual presentations and biopsy should be taken if patients do not show an optimal and desired improvement after receiving a full-course of antibiotic therapy for cellulitis.

Candida albicans rarely infects the lacrimal drainage system. This paper describes a case of bilateral C. albicans dacryocystitis following midfacial trauma. The patient presented with recurrent facial cellulitis and a fistula opening onto the cheek. The condition was controlled only after bilateral dacryocystorhinostomy along with amphotericin B therapy. This appears to be the first reported case in which the lacrimal sacs acted as a reservoir for microorganisms causing recurrent facial cellulitis. PMID:7127203

Successful Treatment of Steroid-Dependent Eosinophilic Cellulitis With Cyclosporine  

PubMed Central

Eosinophilic cellulitis (EC) is a rare idiopathic disorder, first described as a "recurrent granulomatous dermatitis with eosinophilia", that mimics cellulitis of infectious origin. We describe here a previously healthy 11-year-old girl who experienced fever and tender erythematous patch lesions after trauma to her knees. Because of the relapsing cellulitis-like skin lesions, skin biopsies were taken, resulting in a diagnosis of EC. The patient responded well to oral prednisolone but experienced side effects and relapse during dose tapering. She was switched from prednisolone to cyclosporine. Her EC remained under control, and she showed no evidence of relapse after discontinuation of cyclosporine. PMID:23277881

Orbital cellulitis complicated by central retinal artery occlusion.  

PubMed

The authors present a case of a 16-year-old boy who sought treatment in Storm Eye Institute for orbital cellulitis complicated by central retinal artery occlusion. He was examined for severe signs of orbital cellulitis, including decreased vision and an afferent pupillary defect. Intravenous antibiotics failed to provide timely improvement, and the patient was surgically managed with endoscopic orbital decompression. An ocular examination under anesthesia revealed retinal ischemia in the affected eye, and fluorescein angiography confirmed the diagnosis of central retinal artery occlusion. The patient's vision improved slightly following resolution of the infection. Central retinal artery occlusion is a rare complication of orbital cellulitis in adults and has yet to be reported in the pediatric population. PMID:23128536

Two cases of cellulitis in the course of African tick bite fever: a fortuitous association?  

PubMed

In African tick bite fever (ATBF), inoculation eschar - resulting from disruption of the cutaneous barrier - may be a risk factor for cellulitis. We report 2 cases of ATBF associated with cellulitis. A 77-year-old woman was referred for severe leg cellulitis upon returning from sub-Saharan Africa. She developed erythematous macules. Rickettsia africae was detected by PCR assay from a skin biopsy specimen, and ATBF diagnosis was confirmed. A 75-year-old man was hospitalized after his return from Zimbabwe for a maculopapular exanthema and erysipelas-like rash of the leg. The diagnosis of cellulitis associated with ATBF was confirmed by PCR and serological methods. Both patients were treated for ATBF and cellulitis by a combination of doxycycline and beta-lactam antibiotics, and both had a good recovery. Inoculation eschar may be a risk factor for cellulitis; thus, we hypothesize a non-fortuitous association between ATBF and cellulitis. PMID:18503259

Orbital cellulitis following silicone-sponge scleral buckles  

PubMed Central

Background Acute or chronic infection of the scleral explant is rare. We report seven cases of scleral explant infections that caused orbital cellulitis. Materials and methods This was a retrospective chart review of oculoplastics at oculoplastics and vitreo-retinal units in a secondary referral hospital. All subjects had orbital cellulitis secondary to scleral buckle in the range of January 1990 to March 2010. Demographics, imaging studies, and pathology specimens were reviewed. Results A total of 841 silicone-sponge scleral buckle implants for rhegmatogenous retinal detachment were performed. Forty were extracted (4.75%; annual rate of 1.9 cases). Seven (0.83%) had orbital cellulitis. The mean time from implantation to presentation was 5.7 years. There was bacterial growth in all specimens, with Staphylococcus aureus in four. Conclusions Patients who are operated on with silicone-sponge scleral buckling for rhegmatogenous retinal detachment sometimes require removal of the implant because of infection. However, the infection rate is low. Patients should be followed in the long term for possible complications. PMID:24204118

Clostridial dermatitis and cellulitis: an emerging disease of turkeys.  

PubMed

Clostridial dermatitis of turkeys (CDT) has emerged as a major issue across most geographic regions of the United States. The prevalence and severity of dermatitis has increased over the last several years, since the time it was first reported in 1993. Cellulitis in poultry can be associated with Staphylococcus aureus or Escherichia coli, but the more recent field situation in turkeys is specifically associated with Clostridium spp. The prevalence of cellulitis is relatively low; however, the disease can be devastating in the individual flocks affected. Clostridium septicum, Clostridium perfringens, Clostridium sordelli, and S. aureus can cause cellulitis. Escherichia coli, Streptococcus spp., and other bacteria have occasionally been isolated from birds diagnosed with cellulitis. CDT appears as excessive mortality in older birds around 16-18 weeks of age. It has been reported from field experience as early as 7 wk of age. Clinical signs of CDT can range from sudden death to inappetence, depression, leg weakness, recumbency, and ataxia. The disease is characterized by reddish to dark or greenish discoloration of the skin around the thighs, abdomen, keel, tail region, back, and wings. The lesions can extend into the underlying muscles, and there can be gas bubbles under the skin which result in crepitation. Some cases present with dead birds having "bubbly tail," fluid-filled blisters associated with broken feather follicles around the base of the tail. Bubbly tail in breeder toms might not cause excessive mortality, but the lesions are so severe that the birds cannot be used for semen collection. Incidence of mortality from this condition can be severe and acute (i.e., rapid onset of high mortality). The dead birds decompose very quickly. Microscopically, there is necrosis, with or without inflammation of the skin, especially in the dermis and occasionally in the skeletal muscles, associated with large numbers of rod-shaped bacteria. Overcrowding, aggressive birds, poor-wet litter, decreased down time, a contaminated environment including feed and water, poor hygienic conditions, and contaminated vaccines and vaccine equipment, etc., can predispose birds for CDT. Preventative measures and treatment are discussed extensively in this review. PMID:20608520

Mouillage de surfaces hétérogènes : cellule de Hele-Shaw imparfaite  

NASA Astrophysics Data System (ADS)

We study the influence of the surface wettability defects on the behavior of a liquid front advancing in a thin Hele-Shaw cell. Defects are made by spraying ink or by deposition of a photosensitive resin on a glass surface, giving a well-characterized system with controlled defects. We have done an experimental and theoretical study of the interface motion past a single defect. The main result is the existence of a pinning transition: the contact line cannot move over defects that are too large and an air bubble remains trapped on the defect. Smaller defects do hold the contact line for a while, but they are eventually wetted by the advancing liquid. We determine the critical defect size for this transition and calculate the equilibrium shapes of the interface in a two-dimensional geometry. We also investigate the motion of an interface moving over multiple defects. We analyze the relation between the statistical properties of the wetting front as function of the geometrical properties of the defect distribution and gravity effects. Nous avons étudié l'influence des défauts de mouillabilité sur la morphologie d'un front de mouillage avançant dans une cellule mince, dite cellule de Hele-Shaw. Nous avons mis au point la réalisation des cellules minces, la fabrication de défauts et leur caractérisation ainsi qu'un dispositif optique nous permettant de visualiser les déformations successives du front de mouillage. Nous avons étudié expérimentalement et théoriquement l'interaction entre l'interface et un défaut de mouillabilité isolé. Nous avons mis en évidence la transition entre un régime de "décrochage" et de "piégeage": si le défaut est suffisamment fort, la ligne de contact reste accrochée sur le défaut et le front liquide ne peut progresser qu'en laissant une bulle d'air sur le défaut, une partie de la surface solide restant alors non mouillée. Sur un défaut faible, en revanche, la ligne de contact ne fait que se déformer momentanément et la surface solide est finalement entièrement recouverte par le liquide. Nous avons calculé les formes d'équilibre de l'interface en faible et forte déformation en géométrie bidimensionnelle et déterminé expérimentalement la force critique du défaut associée à cette transition. Nous avons examiné le comportement du front de mouillage sur des défauts de mouillabilité multiples, situation qui correspond aux applications industrielles. Nous examinons l'influence de la répartition des défauts et de la gravité sur l'amplitude de fluctuation du front de mouillage. L'analyse statistique de ces systèmes permet d'établir des corrélations entre la distribution de défauts sur le substrat et le comportement de l'interface liquide.

Role of Clostridium perfringens and Clostridium septicum in causing turkey cellulitis.  

PubMed

The role of Clostridium perfringens and Clostridium septicum in the development of cellulitis and mortality in turkey poults was examined. Studies were done in turkeys of two age groups: 3-wk-old and 7-wk-old turkey poults. The effect of varying doses of C. perfringens and C. septicum in reproducing cellulitis lesions and mortality in turkeys was investigated. Both in vitro and in vivo assays were conducted to study their toxic and biologic activities. Clostridium septicum spore culture was found to be more potent than that of C. perfringens in both in vitro assays, such as the hemolysis test, and in vivo assays in mice and turkeys. Both C. perfringens and C. septicum spore cultures were found to be capable of inducing cellulitis lesions and mortality in turkey poults when inoculated by subcutaneous route. Histopathology examination of affected tissues revealed a "moth-eaten appearance, with abundant growth of C. perfringens and C. septicum in the sarcomeres of muscle tissues and in the subcutaneous tissues. However, C. septicum was found to be more potent than C. perfringens in causing cellulitis lesions and mortality in turkeys. Three-week-old poults were found to be less susceptible than 7-wk-old poults in the development of cellulitis lesions and mortality after inoculation with either spore cultures of C. perfringens or C. septicum. The results of the current study suggest that although C. septicum is more potent in causing cellulitis lesions and mortality, infection with either C. septicum or C. perfringens can cause cellulitis lesions and mortality in turkeys.

Evidence of streptococcal origin of acute non-necrotising cellulitis: a serological study.  

PubMed

Bacteriological diagnosis is rarely achieved in acute cellulitis. Beta-haemolytic streptococci and Staphylococcus aureus are considered the main pathogens. The role of the latter is, however, unclear in cases of non-suppurative cellulitis. We conducted a serological study to investigate the bacterial aetiology of acute non-necrotising cellulitis. Anti-streptolysin O (ASO), anti-deoxyribonuclease B (ADN) and anti-staphylolysin (ASTA) titres were measured from acute and convalescent phase sera of 77 patients hospitalised because of acute bacterial non-necrotising cellulitis and from the serum samples of 89 control subjects matched for age and sex. Antibiotic treatment decisions were also reviewed. Streptococcal serology was positive in 53 (69 %) of the 77 cases. Furthermore, ten cases without serological evidence of streptococcal infection were successfully treated with penicillin. Positive ASO and ADN titres were detected in ten (11 %) and three (3 %) of the 89 controls, respectively, and ASTA was elevated in three patients and 11 controls. Our findings suggest that acute non-necrotising cellulitis without pus formation is mostly of streptococcal origin and that penicillin can be used as the first-line therapy for most patients.

Value of needle aspiration in bacteriologic diagnosis of cellulitis in adults.  

PubMed Central

We prospectively studied 30 adult patients with cellulitis, including many who were hospitalized with significant underlying medical problems. Needle aspiration of both central and leading edge areas of their lesions was performed in an attempt to establish a bacteriologic diagnosis. Potential pathogens were isolated by this technique in only 10% of the patients. Neither site of aspiration was clearly superior in terms of culture yield. Because aspirate Gram stains and cultures so rarely provided useful bacteriologic information, they were seldom helpful in guiding antibiotic selection or in influencing the outcome of treatment in most patients. However, clinical information, as well as results of primary lesion cultures when obtainable, may be used to successfully select therapy in most cases of adult cellulitis. On the basis of our results, needle aspiration may not be justified as a routine diagnostic procedure for all adults with cellulitis, though it may still be useful in selected patients. PMID:3356783

A case of odontogenic orbital cellulitis causing blindness by severe tension orbit.  

PubMed

We report a very rare case of odontogenic orbital cellulitis causing blindness by severe tension orbit. A 41-yr old male patient had visited the hospital due to severe periorbital swelling and nasal stuffiness while he was treated for a periodontal abscess. He was diagnosed with odontogenic sinusitis and orbital cellulitis, and treated with antibiotics. The symptoms were aggravated and emergency sinus drainage was performed. On the next day, a sudden decrease in vision occurred with findings of ischemic optic neuropathy and central retinal artery occlusion. Deformation of the eyeball posterior pole into a cone shape was found from the orbital CT. A high-dose steroid was administered immediately resulting in improvements of periorbital swelling, but the patient's vision had not recovered. Odontogenic orbital cellulitis is relatively rare, but can cause blindness via rapidly progressing tension orbit. Therefore even the simplest of dental problems requires careful attention.

Delayed breast cellulitis: An evolving complication of breast conservation  

SciTech Connect

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.

Rapid resolution of cellulitis in patients managed with combination antibiotic and anti-inflammatory therapy.  

PubMed

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.

Abdominal Cellulitis following a Laparoscopic Procedure: A Rare and Severe Complication  

PubMed Central

Advantages of laparoscopic approach in Hirschsprung disease have been already published decreasing the hospital stay and postoperative adhesions. To our knowledge, we report the first case of postoperative abdominal cellulitis after laparoscopic procedure. A laparoscopic Duhamel pull through was done on a 3-month-old child. Full-thickness biopsy under laparoscopy was performed with intraperitoneal inoculation. Large peritoneal irrigation was used. Abdominal necrotizing cellulitis starting from a port site occurred few days after the procedure requiring repeat surgical excision, broad spectrum antibiotics, and hyperbaric oxygen. PMID:25755975

Association between cellulitis (enlarged sternal bursa) and focal ulcerative dermatitis in Ontario turkeys at the time of processing.  

PubMed

We conducted a processing plant survey to determine the prevalence of cellulitis (enlarged sternal bursa) and focal ulcerative dermatitis (FUD) in Ontario turkeys during the summer and to establish whether the two conditions were associated. A total of 11,772 birds from 24 different farms were observed at three processing plants in Ontario between June and August 2001. Each bird was examined for the presence of cellulitis and FUD. The severity and location of lesions were also noted. The overall prevalence of severe cellulitis (requiring either extensive trimming or condemnation of the bird) was 8.8% (95% confidence interval [CI] = 6.7, 10.9) and the overall prevalence for FUD was 22.6% (19.3, 25.9). The Pearson correlation coefficient between the prevalences of the two lesions was 0.56 (P = 0.0043), suggesting farms with a high prevalence of FUD in their birds also had a high prevalence of cellulitis. More specifically, birds with FUD were, on average, 10.8 times more likely to have cellulitis than birds without FUD (Mantel-Haenszel summary odds ratio = 10.8; 95% CI = 9.5, 12.3). Our observations suggest FUD may predispose birds to cellulitis, in which case, preventing FUD may reduce the occurrence of cellulitis condemnations in turkeys. PMID:14562879

Evidence for Clostridium septicum as a primary cause of cellulitis in commercial turkeys.  

PubMed

Etiology and methods of immunoprophylaxis against common field cellulitis in commercial turkeys were evaluated. It was determined that intravenous administration ( approximately 10(8) cells/ml) of 1 of 4 isolates of Clostridium septicum from cellulitis lesions rapidly caused the classic lesions of cellulitis followed by death within 36 hr at high doses. When the supernatant alone was injected into turkey poults, signs of depression and ataxia were temporarily observed for up to 20 hr after injection, but no cellulitis lesions were detected. An enzyme-linked immunosorbent assay was developed to measure antibody levels against the isolated C. septicum. This assay was used to predict susceptibility to infection. An experimental formalin-killed bacterin/toxoid was produced from the challenge strain of C. septicum with inactivation timed to allow toxin accumulation and approximately 10(8) cells/ml. This bacterin/toxoid given at day of hatch generated a rapid and persistent antibody response against the homologous C. septicum in the vaccinated birds at 9 weeks (P < 0.001). The ability of this experimental vaccine to protect birds in the field as well as its ability to evaluate unvaccinated flocks to establish the time of seroconversion and the relationship to clinical disease are currently under evaluation.

The air forces on a systematic series of biplane and triplane cellule models  

NASA Technical Reports Server (NTRS)

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.

Flucloxacillin alone or combined with benzylpenicillin to treat lower limb cellulitis: a randomised controlled trial  

PubMed Central

Objective: To determine whether using intravenous benzylpenicillin in addition to intravenous flucloxacillin would result in a more rapid clinical response in patients with lower limb cellulitis. Methods: This was a randomised controlled trial set in an inner city teaching hospital, comprising 81 patients with lower limb cellulitis requiring intravenous antibiotics. The main outcome measure was the mean number of doses of antibiotic required until clinical response. Results: The mean number of doses required was 8.47 (95% confidence interval (CI) 7.09 to 9.86) in the benzylpenicillin and flucloxacillin combined group. In the flucloxacillin only group it was 8.71 doses (95% CI 6.90 to 10.5), a mean difference of –0.24 doses (95% CI –2.48 to 2.01, p = 0.83). Other markers of treatment efficacy showed no difference between groups at review the following day; temperature decrease (mean difference –0.07°C, 95% CI –0.76 to 0.62, p = 0.84), or diameter decrease of affected area (mean difference –34 mm, 95% CI –99 to 31, p = 0.30). Patient subjective assessments were also similar between the different drug regimen; improvement on a visual analogue scale of pain/discomfort from admission to first review (mean difference 10 mm, 95% CI –12.6 to 14.2, p = 0.91) and on second review (mean difference 15 mm, 95% CI –18.6 to 21.6, p = 0.88). Patient overall subjective feelings of improvement on first review (p = 0.32) and on second review (p = 0.64) were also similar. Conclusions: This study provides no evidence to support the addition of intravenous benzylpenicillin to intravenous flucloxacillin in the treatment of lower limb cellulitis. PMID:15843702

A 6 years old female bernese mountain dog was seen for a nodular and erythemato-edematous dermatosis resistant to therapy. The histopathological exam showed a eosinophilic cellulitis with flame figures, which are caracteristic for the Wells' syndrome in human. A combined treatment with marbofloxacin and prednisolone brought first a stabilisation of the disease. The cutaneous lesions worsened however at the end of the antibiotic treatment, after reduction of the steroid dosage. The prescription of dapsone did not change the clinical image, which motivated the owner to euthanize the dog. This case report is presented to make practitioners aware of a rare but particularly challenging dermatological problem. PMID:21043027

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. PMID:25556256

Regional and national review of factors associated with burn wound cellulitis.  

PubMed

Burn wound cellulitis (BWC) is the second leading complication reported in burns. In this study we sought to identify demographic variables, burn factors, and other factors that may predispose patients to BWC. Regional data was obtained through retrospective medical record review of burn patients treated between May 2009 to April 2013 for BWC within 8 days of the injury. The patients were matched 1:2 with contemporaneously treated patients. Similarly, the National Burn Repository was queried to identify burn patients with BWC between the years 2002 to 2011, which were then compared to the remaining entries who did not have BWC reported. The data sets were analyzed separately. Univariate and multiple variable analyses were performed to evaluate risk factors for BWC. The risk factors that were consistent regionally and nationally were older age, male sex, African-American race (protective), lower extremity burns, scald burns, and full thickness burns. The treatment delay was only collected regionally, and was associated with an eight times increased risk. The factors that were inconsistent or significant in one sample only were smoking status, psychiatric conditions, upper extremity burns, and the place of injury. Cellulitis remains a significant problem for the burn community. Future prospective analyses need to clarify the impact of these factors as well as other factors on the development of BWC. Preventing BWC from occurring through earlier intervention or targeted prophylactic antibiotics may help reduce morbidity and decrease associated healthcare costs. PMID:25102232

Marked worsening was noted despite intramuscular ceftriaxone treatment for 3 days, with marked proptosis, conjunctival chemosis, and a frozen eye. Orbital cellulitis was suspected. Ceftriaxone was intravenously administered. Orbital computed tomography (CT) disclosed an inflammatory process in the medial aspect of the left orbit with ethmoiditis. Improvement was not noted after external ethmoidectomy and drainage of the intraconal abscess. Repeat CT showed a recurrent intraconal abscess. A revision external ethmoidectomy was performed, and a bent wooden match was removed from the posterior aspect of the ethmoidal sinus, after which significant clinical improvement was noted. In patients with CIPA, accidental or self-penetrated foreign bodies must be kept in mind when treating all types of wounds. PMID:14752319

Pemphigus foliaceus-like drug reaction in a 3-month-old crossbreed dog treated for juvenile cellulitis.  

PubMed

Two weeks after administration of routine vaccinations, a 3-month-old, male crossbreed dog developed cutaneous lesions that were clinically and histopathologically consistent with a diagnosis of juvenile cellulitis. The patient was treated with systemic antibacterial, antibacterial ophthalmic ointment and nonsteroidal anti-inflammatory drugs. Within 1 week, new skin lesions that were clinically, histopathologically and immunohistochemically consistent with pemphigus foliaceus developed. The latter completely resolved following drug withdrawal, suggesting a pemphigus foliaceus-like drug reaction. However, the initial lesions persisted and required glucocorticoid therapy to effect resolution. To the authors' knowledge, this is the first reported case of a puppy developing juvenile cellulitis followed by a pemphigus foliaceus-like reaction shortly thereafter, in response to drug therapy.

The underlying immunologic defect is the result of accidental or iatrogenic penetrating wounds on the medial aspect of the thigh or lower limb overlying the greater saphenous vein, because the primary lymphatic drainage vessels are adjacent to this structure. Cracking/fissuring of the skin associated with chronic fungal infection of the feet ("athlete's foot"), most commonly mixed bacterial/fungal interdigital involvement, provides a portal of entry for opportunistic organisms. Bacteria and their products are cleared more slowly in the lymphatic-disrupted and therefore immunologically impaired limb, producing broad areas of dermatitis and around the scars quite distinct from other forms of superficial infection. This rarely develop in otherwise normal limbs. The dermatitis of RLCS and its systemic effects clear with antibiotics but recur intermittently until the tinea pedis is eradicated. The contralateral limb with normal lymphatic structures never develops clinical evidence of infection even though bilateral tinea infection is almost always present. This confirms the central role of an anatomically induced immunocompromised district (ICD) in this syndrome. PMID:25160103

Hypertrophic Osteoarthropathy Presenting as Unilateral Cellulitis with Successful Treatment Using Pamidronate Disodium  

PubMed Central

Hypertrophic pulmonary osteoarthropathy is a paraneoplastic syndrome seen in patients with lung cancer. This condition is characterized by the presence of digital clubbing, periosteal thickening, synovial thickening, and severe pain of the affected joints. Other syndromes exhibiting clubbing may or may not have underlying diseases causing their manifestation. An example is primary hypertrophic osteoarthropathy, or pachydermoperiostosis. While clubbing makes up part of the clinical picture in both hypertrophic pulmonary osteoarthropathy and hypertrophic osteoarthropathy, the latter has no underlying disease associations. Rather, primary hypertrophic osteoarthropathy is familial, idiopathic, and has a chronic course often beginning during puberty in males. Secondary hypertrophic osteoarthropathy is an acquired form of clubbing that is classically associated with lung disease. However, it has also been associated with diseases of the heart, liver, and intestines. In the setting of pulmonary malignancy, secondary hypertrophic osteoarthropathy is known as hypertrophic pulmonary osteoarthropathy. Hypertrophic pulmonary osteoarthropathy has a distinct constellation of clinical findings that includes intractable pain often refractory to treatments other than resolution of the underlying disease process. The authors herein report a case of hypertrophic pulmonary osteoarthropathy masquerading as recurrent lower extremity cellulitis with chronic hand and foot pain in the setting of pulmonary malignancy that responded dramatically to intravenous pamidronate disodium (a bisphosphonate). Given the rarity of hypertrophic osteoarthropathy associated with lung cancer and the difficulty with pain management in such circumstances, the authors present the following case in which pain was mitigated by treatment with bisphosphonate therapy.

A case of cellulitis of the hands caused by a predatory bird attack  

PubMed Central

Many species have been drastically affected by rapid urbanization. Harris's hawks from their natural habitat of open spaces and a supply of rodents, lizards and other small prey have been forced to change their natural environment adapting to living in open spaces in sub- and peri-urban areas. Specific areas include playgrounds, parks and school courtyards. The migration of this predatory species into these areas poses a risk to individuals, and especially the children are often attacked by claws, talons and beaks intentionally or as collateral damage while attacking rodent prey. In addition, the diverse micro-organisms harbored in the beaks and talons can result in wound infections, presenting a challenge to clinical management. Here we would like to present a case of an 80-year-old man with cellulitis of both hands after sustaining minor injuries from the talons of a Harris's hawk and review the management options. We would also like to draw attention to the matter that, even though previously a rarity, more cases of injuries caused by birds of prey may be seen in hospital settings. PMID:23569751

Cassures double-brin de l'ADN, cassures chrosomiques et létalité des cellules humaines irradiées  

NASA Astrophysics Data System (ADS)

DNA double-strand breaks (DSB) are the likely event which may explain the radiation-induced killing effect in mammalian cells. An overview of the litterature shows that, to the exception of a small group of human tumours, the repair defect rather than the induction rate of DSB plays the major role. However, the arguments supporting the relationship between DSB and intrinsic radiosensitivity are most often indirect. Our results dealing with intrinsic radiosensitivity, residual DNA DSB and chromosome breaks have been achieved with untransformed human fibroblasts (5 control and 18 hypersensitive cell lines). We describe a quantitative relationship between the intrinsic radiosensitivity and the residual breaks. The death of a human fibroblast is linked to 1.3 unrepaired chromosome break and 6.6 unrepaired DSB. Les cassures double-brin (CDB) de l'ADN constituent l'événement-clé susceptible d'expliquer l'effet létal des radiations ionisantes. Une revue générale de la littérature montre que, à l'exception d'un groupe minoritaire de tumeurs humaines, c'est surtout une déficience de réparation plutôt que l'incidence des dégâts qui est associée à la mort des cellules de mammifères irradiées. Toutefois, les arguments en faveur d'un lien entre radiosensibilité et CDB sont généralement indirects. À partir de 23lignées fibroblastiques humaines (5témoins et 18hypersensibles), nous décrivons une relation quantifiée entre la radiosensibilité intrinsèque et les cassures résiduelles de l'ADN et des chromosomes. La mort d'un fibroblaste humain irradié est associée à 6,6 CDB et 1,3 cassure chromosomique non réparées.

Clinico-radiologic findings in primary cutaneous extranodal natural killer/t-cell lymphoma, nasal type mimicking cellulitis of the left arm.  

PubMed

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. PMID:25793085

A Homeopathic Arnica Patch for the Relief of Cellulitis-derived Pain and Numbness in the Hand  

PubMed Central

Objectives: Arnica montana, belonging to the Compositae family, is a plant with a longstanding tradition of relieving pain and/or inflammation in muscles and joints and may thus represent an alternative to nonsteroidal antiinflammatory drugs, which are often ineffective or lead to a number of adverse effects. A homeopathic arnica patch (3X dilution according to the Homeopathic Pharmacopoeia of the United States) was developed to alleviate pain symptoms in the back and neck muscles and joints. Case Presentation: The present case report describes the treatment outcome after administration of the arnica patch in a 55-year-old female patient with pain in the right hand and numbness in the fourth finger after cellulitis in the palmar area. The cellulitis was treated with antibiotics, but pain symptoms remained at 7 points on a 0-to-10–point visual analog scale (VAS) for pain despite intake of oral ibuprofen and oral and topical application of an arnica-containing complex homeopathic ointment. Ten arnica patches were dispensed to the patient. She cut the patch into strips to cover all painful areas of the hand and applied them at night. After 3 days, she reported a substantial decrease in pain symptoms (VAS = 1) and a marked decrease in numbness and in the size of a tender nodule on the third metacarpal area. Moreover, the patient was able to sleep through the night without being awakened by the pain. The symptoms declined further during the next 2 days. Conclusion: This case demonstrates that after a relatively short period of time, the administration of the arnica patch on the hand provided a marked reduction of pain and recovery of functionality of the hand.

Feasibility study to inform the design of a UK multi-centre randomised controlled trial of prophylactic antibiotics for the prevention of recurrent cellulitis of the leg  

PubMed Central

Background This paper describes the results of a feasibility study for a randomised controlled trial (RCT). Methods Twenty-nine members of the UK Dermatology Clinical Trials Network (UK DCTN) expressed an interest in recruiting for this study. Of these, 17 obtained full ethics and Research & Development (R&D) approval, and 15 successfully recruited patients into the study. A total of 70 participants with a diagnosis of cellulitis of the leg were enrolled over a 5-month period. These participants were largely recruited from medical admissions wards, although some were identified from dermatology, orthopaedic, geriatric and general surgery wards. Data were collected on patient demographics, clinical features and willingness to take part in a future RCT. Results Despite being a relatively common condition, cellulitis patients were difficult to locate through our network of UK DCTN clinicians. This was largely because patients were rarely seen by dermatologists, and admissions were not co-ordinated centrally. In addition, the impact of the proposed exclusion criteria was high; only 26 (37%) of those enrolled in the study fulfilled all of the inclusion criteria for the subsequent RCT, and were willing to be randomised to treatment. Of the 70 participants identified during the study as having cellulitis of the leg (as confirmed by a dermatologist), only 59 (84%) had all 3 of the defining features of: i) erythema, ii) oedema, and iii) warmth with acute pain/tenderness upon examination. Twenty-two (32%) patients experienced a previous episode of cellulitis within the last 3 years. The median time to recurrence (estimated as the time since the most recent previous attack) was 205 days (95% CI 102 to 308). Service users were generally supportive of the trial, although several expressed concerns about taking antibiotics for lengthy periods, and felt that multiple morbidity/old age would limit entry into a 3-year study. Conclusion This pilot study has been crucial in highlighting some key issues for the conduct of a future RCT. As a result of these findings, changes have been made to i) the planned recruitment strategy, ii) the proposed inclusion criteria and ii) the definition of cellulitis for use in the future trial.

Life of lesions in eosinophilic cellulitis (Wells' syndrome)-a condition that may be missed at first sight.  

PubMed

: Eosinophilic cellulitis is an inflammation of, until now, unknown etiology that was first described by George Wells in 1971. Its dominating histological hallmarks are so-called "flame figures" and an eosinophilic infiltrate. Here, we report the case of a 46-year-old man who initially presented with excoriated papules that were histologically interpreted as consistent with "arthropod reactions." Later on, the clinical presentation changed to erythematous plaques, partially with cockade-like aspects. At this time, new biopsies were performed showing a superficial and deep perivascular lymphocytic and heavily eosinophilic infiltrate and flame figures, thus allowing to establish the diagnosis of Wells' syndrome. Under treatment with oral prednisolone and dapsone, the patient showed a rapid improvement of the condition. The presented case demonstrates both the clinical and histopathologic life of lesions of Well's syndrome in the course of the disease from unspecific to distinctive. The need for repeated biopsies is discussed. Current understanding of the pathogenesis of Wells' syndrome and its correlating histological features are elucidated. PMID:25238447

Oral flucloxacillin and phenoxymethylpenicillin versus flucloxacillin alone for the emergency department outpatient treatment of cellulitis: study protocol for a randomised controlled trial  

PubMed Central

Background Oral flucloxacillin, either alone or in combination with phenoxymethylpenicillin, is a commonly prescribed antibiotic for the treatment of cellulitis, particularly in Ireland and the United Kingdom. This study aims to establish the non-inferiority of oral monotherapy (flucloxacillin alone) to dual therapy (flucloxacillin and phenoxymethylpenicillin) for the outpatient treatment of cellulitis in adults. Methods/design This study is a multicentre, randomised, double-blind, placebo-controlled trial of adults who present to the emergency department (ED) with cellulitis that is deemed treatable on an outpatient basis with oral antibiotics. After fulfilling specified inclusion and exclusion criteria, informed consent will be taken. Patients will be given a treatment pack containing 7 days of treatment with flucloxacillin 500 mg four times daily and placebo or flucloxacillin 500 mg four times daily and phenoxymethylpenicillin 500 mg four times daily. The primary outcome measure under study is the proportion of patients in each group in which there is greater than or equal to a 50% reduction in the area of diameter of infection from the area measured at enrolment at the end-of-treatment visit (7 to 10 days). Secondary endpoints include a health-related quality of life measurement as rated by the SF-36 score and the Extremity Soft Tissue Infection Score (not validated), compliance and adverse events. Patients will be followed up by telephone call at 3 days, end-of-treatment visit (EOT) at 7 to 10 days and test-of-cure (TOC) visit at 30 days. To achieve 90% power, a sample size of 172 patients per treatment arm is needed. This assumes a treatment success rate of 85% with oral flucloxacillin and phenoxymethylpenicillin, an equivalence threshold ? = 12.5% and an ? = 0.025. Non-inferiority will be assessed using a one-sided confidence interval on the difference of proportions between the two groups. Standard analysis including per-protocol and intention-to-treat will be performed. Discussion This trial aims to establish the non-inferiority of flucloxacillin monotherapy to dual therapy in the treatment of uncomplicated cellulitis among ED patients. In doing so, this trial will bridge a knowledge gap in this understudied and common condition and will be relevant to clinicians across several different disciplines.

Fragmentation radioinduite de l'ADN et réparation étudiée par immunomarquage anti poly(ADP-ribose)polymérase (PARP) dans les cellules de hamster chinois (CHO)  

NASA Astrophysics Data System (ADS)

The poly(ADP-ribose)polymerase is a nuclear ubiquitous enzyme capable of binding to DNA breaks. Chinese hamster ovary cells were (CHO-K1) cultured on slides and ?-irradiated (137Cs) at a high (12.8 Gy/min) or medium dose rate (5 Gy/min), and immunolabelling against (ADP-ribose) polymers immediatly or three hours after irradiation. Quantification and localisation of ?-ray induced breaks was performed by confocal microscopy. The results show a dose effect relationship, a dose-rate effect and the signal disappearence after 3 hours at 37 °C. The presence of PARP activity appears to reflect ?-rays induced DNA fragmentation. Le poly(ADP-ribose)polymérase est une enzyme nucléaire ubiquitaire capable de se fixer sur les cassures de l'ADN. Sur une lignée sauvage de cellules d'ovaire de hamster chinois (CHO-K1) cultivée sur lame et irradiée aux rayons ? à haut débit de dose (HD) 12,8 Gy/min ou à moyen débit de dose (MD) 5 Gy/min, nous avons réalisé un immunomarquage anti-polymères d'ADP-ribose immédiatement après l'irradiation ? ou après trois heures d'incubation à 37 °C. La quantification et la localisation des lésions radioinduites ont été réalisées par microscopie confocale. Les résultats montrent une relation dose-effet et un effet de débit de dose, ainsi qu'une disparition du signal après 3 heures à 37 °C. La présence de la PARP semble donc bien refléter la fragmentation radioinduite de l'ADN.

Human parasitization by oestrid flies is a rare occurrence. The authors report a case of ophthalmomyiasis externa caused by Dermatobia hominis infestation in a 10-year-old female. Misdiagnosis resulted in a delay in treatment, which can be potentially devastating in cases of orbital or ocular involvement. The treatment of choice is early surgical removal of the larvae to minimize the inflammatory response and the extent of surgery. Patients should also be screened for multiple sites of cutaneous infestation. When the organism is completely excised, the prognosis is good. PMID:25226095

A case of cellulitis causing tissue defect during etanercept therapy.  

PubMed

Tumor necrosis factor-alpha (TNF-?) antagonists are employed increasingly during recent years in patients with active rheumatoid arthritis who do not respond to disease-modifying anti-rheumatic drugs. Contraindications such as infections, auto-antibody formation and hypersensitive reactions can be observed during the treatment with TNF-? antagonist drugs. Our case was a 52-year-old woman, followed by several centers for a period of 21 years with a seropositive, erosive and nodular RA diagnosis. Anti TNF-? treatment was commenced due to the failure to control the disease. During the treatment, a serious cellulite developed, which required hospitalization and surgical debridement as well as intravenous antibiotics treatment. Through the present case, we aimed to draw attention to the skin infection during the use of etanercept in a patient with RA. PMID:20020139

Intracranial brain abscess preceded by orbital cellulitis and sinusitis.  

PubMed

A 17-year-old boy with pyrexia, headache, and frequent drop attacks reported an acute onset of periorbital pain and swelling 1 month previously. Coronal computed tomography (CT) identified an ethmoid sinusitis, which was treated with functional endoscopic sinus surgery and intravenous gentamicin, prostaphylline, and metronidazone. Because of persistent symptoms, the patient returned 1 month later. The CT identified accumulation of debris in both frontal sinuses and a multilobulated lesion over the right frontal lobe. Bicoronal craniotomy was performed, and a mass located in the right frontal lobe was excised; the mass comprised chronic inflammatory tissues without evidence of malignancy. A postoperative brain CT confirmed the absence of a residual mass, and no recurrence or neurologic deficits were noted during the 3-month follow-up period. Intracranial complications cannot be prevented entirely even with the judicious use of antibiotics. Early application of the appropriate imaging modality and institution of aggressive therapy in any patient, not just pediatric patients, to prevent potential long-term disabilities and death are essential.

Influence de revetements bioactifs sur les cellules endotheliales: Vers des protheses vasculaires non thrombotiques  

NASA Astrophysics Data System (ADS)

Developing vascular prostheses of small diameter to replace vessels closed by atherosclerosis remains a challenge because of the risk of thrombosis. Seeding of endothelial cells, which have antithrombogenic properties, is a promising solution, but we must create surfaces which promote their adhesion and retention to resist shear stresses created by the blood flow on the surface. This master's project aimed at investigating the effect of a plasma polymerized coating rich in primary amines (called LP), with or without elements of the extracellular matrix (Fibronectin (FN) or chondroitin sulphate (CS)) on the endothelial cells and hemocompatibility of polyethylene terephthalate (PET). The adhesion, growth and retention of human umbilical vein endothelial cells (HUVECs) on PET and LP, in the presence and absence of FN or CS, have been studied. In addition, platelet adhesion on different surfaces was evaluated by a perfusion test with whole blood, platelets being previously labeled with rhodamine. Finally a double fluorescent labeling (using Cellview Maroon to mark the HUVECs and CD61 antibody for platelets) was developed to study the retention of endothelial cells, under blood flow and verify their non thrombogenic character. The results obtained show that both the LP coating and the adsorbed FN, strongly increase both the cellular adhesion and growth on PET; however they have no additional effect when the two are combined. They also augment cellular retention to surface, but this remains incomplete. Moreover we observed that the plasma coating (LP) greatly increases the thrombogenicity of the surface, with strong platelet adhesion and activation. This thrombogenicity is extremely reduced when endothelial cells cover the surface, but cell loss under the effect of shear produced by the perfusion creates significant areas of platelet adhesion. The grafting of CS on LP also permits good HUVECs adhesion, growth and retention under shear stress on HUVEC, with no difference from the LP alone. In addition, the CS sharply decreases the platelet adhesion, which is found below the value observed for PET. The double cell labeling also showed that cells adhered on LP+CS has an anti-thrombotic phenotype and can resist blood flow. These studies suggest that a coating of CS is a promising strategy for vascular prosthesis given the combination of the good adhesion of endothelial cells and the low thrombogenicity of the underlying surface. Keywords: vascular prostheses, polymers, bioactive coating, thrombogenicity, HUVECs.

Study Design?Case report. Objective?To report and discuss a rare complication after a patient was treated conservatively with a halo vest. Methods?A 51-year-old man sustained a hangman's injury of the C2 vertebra following a motor vehicle collision. He was treated conservatively in a halo vest appliance and following mobilization was discharged from the hospital. Two weeks after discharge, the patient presented to the emergency department complaining of proptosis, ptosis, diplopia, and pin loosening. He was readmitted to the hospital, the halo vest was removed, and urgent imaging studies including computed tomography scan and magnetic resonance imaging were performed. They revealed that one of the halo pins had penetrated the orbital roof with active infection of the extraocular soft tissues. In consultation with the ophthalmologist, he was treated conservatively with antibiotics for 10 days. Results?His ophthalmologic complaints resolved gradually and his eye returned to normal appearance and function. In the meantime, he was immobilized in a sterno-occipital mandibular immobilizer brace. Conclusion?Though rare, penetrating injuries after cranial pin insertion can occur. Halo devices must be applied by, or under close supervision of, experienced personnel to avoid such complications, and halo vests should be reviewed frequently to detect such incidents early.

Post-mortem CT findings in a case of necrotizing cellulitis of the floor of the mouth (Ludwig angina).  

PubMed

Ludwig angina is a rare but potentially lethal infection of the submandibular space that can cause significant upper airway obstruction. We report a case of undiagnosed Ludwig angina that progressed rapidly to death. Ludwig angina was suspected after post-mortem computed tomography (PMCT) found swollen mylohyoid muscle with stranding in subcutaneous fat, thickening of deep fascia, and local lymphadenopathy. Subsequently, an autopsy revealed woody induration of the submental region and liquefactive necrosis of the mylohyoid muscle, confirming the diagnosis. It is likely that the dental abscess identified on PMCT was the source of infection. Multiple invasive medical procedures were performed on the subject by the ambulance crew prior to his death. PMCT assisted further in determining procedural success. PMID:24150965

Necrotizing cellulitis of the abdominal wall, caused by Pediococcus sp., due to rupture of a retroperitoneal stromal cell tumor  

PubMed Central

INTRODUCTION Soft tissue necrotizing infections are a significant cause of morbidity and mortality. The aim of this study is to present a patient with necrotizing infection of abdominal wall resulting from the rupture of a retroperitoneal stromal tumor. PRESENTATION OF CASE We present a 60-year-old Caucasian male patient with necrotizing infection of abdominal wall secondary to the rupture of a retroperitoneal stromal tumor. The patient was initially treated with debridement and fasciotomy of the anterior abdominal wall. Laparotomy revealed purulent peritonitis caused by infiltration and rupture of the splenic flexure by the tumor. Despite prompt intervention the patient died 19 days later. The isolated microorganism causing the infection was the rarely identified as cause of infections in humans Pediococcus sp., a gram-positive, catalase-negative coccus. DISCUSSION Necrotizing infections of abdominal wall are usually secondary either to perineal or to intra-abdominal infections. Gastrointestinal stromal cell tumors could be rarely complicated with perforation and abscess formation. In our case, the infiltrated by the extra-gastrointestinal stromal cell tumor ruptured colon was the source of the infection. The pediococci are rarely isolated as the cause of severe septicemia. CONCLUSION Ruptured retroperitoneal stromal cell tumors are extremely rare cause of necrotizing fasciitis, and before this case, Pediococcus sp. has never been isolated as the responsible agent.

Simulation numerique de l'effet du reflecteur radial sur les cellules rep en utilisant les codes DRAGON et DONJON  

NASA Astrophysics Data System (ADS)

The pressurized water nuclear reactors (PWRs) is the largest fleet of nuclear reactors in operation around the world. Although these reactors have been studied extensively by designers and operators using efficient numerical methods, there are still some calculation weaknesses, given the geometric complexity of the core, still unresolved such as the analysis of the neutron flux's behavior at the core-reflector interface. The standard calculation scheme is a two steps process. In the first step, a detailed calculation at the assembly level with reflective boundary conditions, provides homogenized cross-sections for the assemblies, condensed to a reduced number of groups; this step is called the lattice calculation. The second step uses homogenized properties in each assemblies to calculate reactor properties at the core level. This step is called the full-core calculation or whole-core calculation. This decoupling of the two calculation steps is the origin of methodological bias particularly at the interface core reflector: the periodicity hypothesis used to calculate cross section librairies becomes less pertinent for assemblies that are adjacent to the reflector generally represented by these two models: thus the introduction of equivalent reflector or albedo matrices. The reflector helps to slowdown neutrons leaving the reactor and returning them to the core. This effect leads to two fission peaks in fuel assemblies localised at the core/reflector interface, the fission rate increasing due to the greater proportion of reentrant neutrons. This change in the neutron spectrum arises deep inside the fuel located on the outskirts of the core. To remedy this we simulated a peripheral assembly reflected with TMI-PWR reflector and developed an advanced calculation scheme that takes into account the environment of the peripheral assemblies and generate equivalent neutronic properties for the reflector. This scheme is tested on a core without control mechanisms and charged with fresh fuel. The results of this study showed that explicit representation of reflector and calculation of peripheral assembly with our advanced scheme allow corrections to the energy spectrum at the core interface and increase the peripheral power by up to 12% compared with that of the reference scheme.

Etude ab initio des proprietes electroniques et optiques d'un systeme donneur-accepteur organique utilise dans les cellules photovoltaiques  

NASA Astrophysics Data System (ADS)

The search for new sources of clean and renewable energy has recently been encouraged by the growing energy demand caused by the industrialization of developing countries and by population growth. In this context, the generation of electricity through the exploitation of solar energy with photovoltaic cells is particularly interesting, since this energy source is largely unused compared to its full potential. Nevertheless, large scale electricity generation with the current design of photovoltaic cells based on silicon is hindered by the large manufacturing cost of these devices. A new generation of photovoltaic cells, which includes organic photovoltaic cells that use semiconducting polymers, is under intense development in order to significantly reduce the manufacturing costs. The replacement of conventional materials with conjugated polymers in photovoltaic cells opens the possibility of using large scale manufacturing processes to produce large-area devices at low cost. However, the power conversion efficiency and the lifetime of organic photovoltaic cells are currently too low for these devices to be cost effective. A better understanding of the organic photovoltaic process is therefore necessary to improve the power conversion efficiency of these devices. The operating principle of photovoltaic cells requires the charge transfer between a polymer acting as an electron donor and a molecule acting as an electron acceptor to enable the dissociation of photogenerated excitons into free charge carriers. Furthermore, to ensure that the majority of the photogenerated excitons dissociates, the active region of an organic photovoltaic cell is typically formed by a bulk heterojunction between the donor and the acceptor. Many experimental studies have shown that the power conversion efficiency of these devices, which is proportional to the product of their short-circuit current Isc with their open circuit potential Voc, is strongly governed by the microstructure of the bulk heterojunction defined as the local order of the two phases and the organization of the donor-acceptor interfaces. Even though these studies have helped to increase the efficiency of organic photovoltaic cells, the relations linking the microstructure of the bulk heterojunction to their electronic and optical properties are still to be established. The objective of the research project is to computationally study the electronic and optical properties of organic bulk heterojunctions composed of regioregular poly(3-hexylthiophene) (rrP3HT) and C60, two materials typically used in organic photovoltaic cells. In this study, the microstructure of the donor-acceptor systems can be directly controlled, which facilitates the systematic study of the influence of this parameter on the electronic and optical properties of the organic bulk heterojunctions. The density functional theory (DFT) is used to study the ground state geometric and electronic properties of multiple bulk heterojunction systems, while the time dependent density functional theory (TDDFT) is used to study the optical properties of these systems. The SIESTA software package is used to study periodic systems representing perfectly crystalline materials. The results obtained in this research project show that the power conversion efficiency of organic photovoltaic cells is strongly modulated by the microstructure of the bulk heterojunctions. Indeed, the size of the rrP3HT crystalline domains must be optimized to maximize the efficiency of the photovoltaic devices, since Voc and Isc have opposite behaviors with respect to ?-stacking of the rrP3HT chains. In addition, the efficiency of organic photovoltaic cells could be improved by imposing geometrical constraints in the bulk heterojunctions through manufacturing methods in order to increase the value of Voc without altering the value of Isc.

SciTech Connect

Thin films of Cd sub(1-y)Zn sub y S (0 < y < 0.2) have been prepared either by thermal evaporation of the powdered solids from a single crucible, or by rapid evaporation from two crucibles. Different methods were used to characterise the films according to their structural, electrical and electron-optical properties as a function of the amount of Zn in the film. Both liquid-phase and solid-phase ion exchange processes have been used to deposit a thin film of Cu/sub 2/S on the Cd sub(1-y)Zn sub y S film to produce a p-n hetero-junction. A study of the growth of the Cd/sub 2/S layer has been carried out. Photocurrents and voltages have been determined for these Cu/sub 2/S-CdZnS cells.

Lesson of the month 1: A rash decision.  

PubMed

Cellulitis is a common condition and several mimics exist which should be considered in patients who fail to respond to antibiotics. We describe the case of a patient with anaplastic large cell lymphoma masquerading as a lower leg cellulitis. The patient had failed to respond to intravenous antibiotics and a skin biopsy confirmed her diagnosis. She received radical radiotherapy to the lower leg but later developed shortness of breath and was identified to have pulmonary infiltration of the lymphoma. She died shortly afterwards from lobar pneumonia. This case highlights the importance of regularly reassessing patients with suspected cellulitis and considering alternative diagnoses in cases that fail to respond to treatment. PMID:25824078

A Spatial Load Forecasting Method Based on the Theory of Clustering Analysis  

NASA Astrophysics Data System (ADS)

The spatial load forecasting method based on time series analysis usually divides predictive zone into cellules, and then forecast the load of each cell based on time series analysis, to predict the whole spatial load. Now there are many prediction models based on time series analysis, but it is hard to realize the minimum of the prediction error for each cell, namely not guarantee the accuracy of results of spatial load forecasting. Thus, the spatial load forecasting method based on the theory of clustering analysis is proposed there. Firstly this method analyzes the results and the relative prediction error of each cell with different load forecasting model. Second, according to the best forecast models, cluster all cellules, which cellules in the same cluster use the same prediction model to forecast the load of cellules of the target year. The results of a practical example show that our method is correct and effective.

Pharmacological treatment for chronic oedema.  

PubMed

Chronic oedema is mainly treated by physical methods (compression, lymphatic drainage, massage and exercise), with drugs not having a major role to play. However, antibiotics are essential in the management of cellulitis, a common and important complication of chronic oedema. Diuretics and cortico-steroids may be appropriate in some types of oedema such as that associated with advanced cancer. Analgesics may be helpful in managing pain, particularly in the short term e.g. pain from cellulitis, although long-term use may also be appropriate, e.g. in cancer pain. Benzopyrones are not routinely used in the management of lymphoedema in the UK. PMID:18595306

Postoperative infection is the most commonly seen complication of surgery in obstetrics and gynecology. The use of antibiotic prophylaxis has greatly decreased though not completely eliminated this adverse outcome. Postoperative infections include wound cellulitis, wound abscess, endomyometritis, pelvic cellulitis, and pelvic abscess. Infections usually manifest as fever and greater than normal postoperative pain. Refractory fevers maybe because of septic pelvic vein thrombophlebitis or maybe noninfectious in origin. Broad-spectrum antibiotics should be initiated as soon as possible when diagnosis of postoperative infection is made; most patients will respond to treatment within 24 to 48 hours when appropriate antibiotics are selected.

Bone scintigraphy for neonatal osteomyelitis: simulation by extravasation of intravenous calcium  

SciTech Connect

Intravenously administered calcium gluconate has become increasingly popular in the treatment of neonatal tetany. Occasionally, extravasation results in cellulitis, leading to a clinical diagnosis of superimposed osteomyelitis. Osseous scintigraphy, as the accepted modality in the early detection of osteomyelitis, would tend to be used in this circumstance. This case illustrates a false-positive result, probably due to soft-tissue calcification.

Carcinome mucineux primitif cutané: à propos de deux cas et d'une revue de la literature  

PubMed Central

Le carcinome mucineux primitif cutané est une tumeur annexielle rare, développée à partir des glandes sudoripares. Il se localise en générale à l'extrémité céphalique, surtout la région périorbitaire. Nous rapportons deux observations d'un carcinome mucineux primitif de la face et de la région axillaire, chez deux patients âgés de 60 ans. L’étude histologique montrait une prolifération tumorale dermohypodermique, faite de cellules organisées en cordons, en amas et en massif cribriformes, au sein d'une substance mucoïde. En immunohistochimie les cellules tumorales exprimaient la cytokératine 7, l'EMA et les récepteurs hormonaux. L'actine musculaire lisse a bien marqué les cellules myoépithéliales au niveau de la composante in situ dans un seul cas. Le carcinome mucineux primitif cutané est difficile à différencier d'une métastase mammaire ou digestive. La mise en évidence de carcinome in situ ou de cellules myoépithéliale est en faveur de l'origine cutanée primitive. C'est une tumeur à croissance lente, avec des métastases exceptionnelles. Le traitement est chirurgical et le taux de récidive est très élevé. Et à travers ces deux observations, les auteurs mettent en relief les principaux aspects cliniques, histologiques, thérapeutiques de cette entité avec une revue de la littérature. PMID:25574316

Caracterisation thermique de modules de refroidissement pour la photovoltaique concentree  

NASA Astrophysics Data System (ADS)

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 a la surface opposee du recepteur pour evacuer la chaleur injectee. Les resultats mettent egalement en evidence l'importance des interfaces thermiques et les avantages de diffuser la chaleur dans les couches metalliques avant de la conduire au travers des couches dielectriques du recepteur. Des recepteurs de multiples compositions ont ete caracterises, demontrant que les outils developpes peuvent definir la capacite de diffusion thermique. La repetabilite de la plateforme est evaluee par l'analyse de l'etendue des mesures repetees sur des echantillons selectionnes. La plateforme demontre une precision et reproductibilite de +/- 0.14 ° C/W. Ce travail fournit des outils pour la conception des recepteurs en proposant une mesure qui permet de comparer et d'evaluer l'impact thermique de ces recepteurs integres a uri module de refroidissement.

Pressure-Distribution Measurements on O-2H Airplane in Flight  

NASA Technical Reports Server (NTRS)

Results are given of pressure-distribution measurements made over two different horizontal tail surfaces and the right wing cellule, including the slipstream area, of an observation-type biplane. Measurements were also taken of air speed, control-surface positions, control-stick forces, angular velocities, and accelerations during various abrupt maneuvers. These maneuvers consisted of push-downs and pull-ups from level flight, dive pull-outs, and aileron rolls with various thrust conditions. The results from the pressure-distribution measurements over the wing cellule are given on charts showing the variation of individual rib coefficients with wing coefficients; the data from the tail-surface pressure-distribution measurements are given mainly as total loads and moments. These data are supplemented by time histories of the measured quantities and isometric views of the rib pressure distributions occurring in abrupt maneuvers.

Pelvic Surgical Site Infections in Gynecologic Surgery  

PubMed Central

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. PMID:25788822

Streptococcus dysgalactiae subsp. equisimilis bacteremia: an emerging infection.  

PubMed

The importance of group C and G Streptococcus dysgalactiae subspecies equisimilis (S. dysgalactiae subsp. equisimilis) as a significant pathogen has recently been better recognized. S. dysgalactiae subsp. equisimilis disease can range in severity from milder skin and soft-tissue conditions such as wound infection, erysipelas, and cellulitis, to life-threatening necrotizing fasciitis and streptococcal toxic shock syndrome, thus sharing the clinical picture with S. pyogenes. The most common clinical manifestation of bacteremia is cellulitis. An increase in the incidence of S. dysgalactiae subsp. equisimilis bacteremia has been recognized. Invasive forms of this infection are most commonly found in elderly patients with underlying comorbidities and skin breakdown. The case fatality in bacteremia has been reported to be 15-18%. In this review, the epidemiology, clinical characteristics, and emm types of S. dysgalactiae subsp. equisimilis bacteremia are summarized. PMID:24682845

Management of acute dental infections requires an understanding of microbiology, anatomy, pharmacology, wound healing, and oral surgery. Recognizing early signs of inflammation and differentiating them from characteristics of an infection facilitates timely intervention and avoids further complications. This article addresses various aspects of the diagnosis and treatment of acute oral infections. Suggestions are made to help differentiate between swelling associated with an infection and edema related to inflammation of nonpathogenic origin. In addition, discussion focuses on how to distinguish between an abscess and cellulitis, when to culture, and which antibiotics to select to resolve an infection. Protocols for managing an infection with and without fluctuance are reviewed. Finally, the consequences of spreading cellulitis are discussed, and signs indicating the need for referral of a patient are delineated. PMID:25822636

Radionuclide imaging in the evaluation of osteomyelitis and septic arthritis  

SciTech Connect

Despite controversy over its exact role, radionuclide imaging plays an important role in the evaluation of patients suspected of having osteomyelitis. The differentiation between osteomyelitis and cellulitis is best accomplished by using a three-phase technique using Tc-99m methylene diphosphonate (MDP). Frequently, it is necessary to obtain multiple projections and magnification views to adequately assess suspected areas. It is recommended that a Ga-67 or In-111 leukocyte scan be performed in those cases where osteomyelitis is strongly suspected clinically and the routine bone scan is equivocal or normal. Repeated bone scan after 48 to 72 h may demonstrate increased radioactivity in the case of early osteomyelitis with the initial photon-deficient lesion. In-111 leukocyte imaging is useful for the evaluation of suspected osteomyelitis complicating recent fracture or operation, but must be used in conjunction with clinical and radiographic correlation. The recognition of certain imaging patterns appears helpful to separate osteomyelitis from septic arthritis or cellulitis. 83 references.

Pelvic surgical site infections in gynecologic surgery.  

PubMed

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. PMID:25788822

Graph Varieties in High Dimension  

E-print Network

We study the \\emph{picture space} $X^d(G)$ of all embeddings of a finite graph $G$ as point-and-line arrangements in an arbitrary-dimensional projective space, continuing previous work on the planar case. The picture space admits a natural decomposition into smooth quasiprojective subvarieties called \\emph{cellules}, indexed by partitions of the vertex set of $G$, and the irreducible components of $X^d(G)$ correspond to cellules that are maximal with respect to a partial order on partitions that is in general weaker than refinement. We study both general properties of this partial order and its characterization for specific graphs. Our results include complete combinatorial descriptions of the irreducible components of the picture spaces of complete graphs and complete multipartite graphs, for any ambient dimension $d$. In addition, we give two graph-theoretic formulas for the minimum ambient dimension in which the directions of edges in an embedding of $G$ are mutually constrained.

Lime-induced phytophotodermatitis.  

PubMed

This case describes a scenario of lime-induced phytophotodermatitis. Phytophotodermatitis is a dermatitis caused after the skin is exposed to photosensitizing compounds in plants and then exposed to sunlight. Many common plants including citrus fruits, celery, and wild parsnip contain these photosensitizing compounds which cause phytophotodermatitis. It is important for a physician to be aware of phytophotodermatitis because it may often be misdiagnosed as other skin conditions including fungal infection, cellulitis, allergic contact dermatitis, and even child abuse.

Radionucleotide scanning in osteomyelitis  

SciTech Connect

Radionucleotide bone scanning can be an excellent adjunct to the standard radiograph and clinical findings in the diagnosis of osteomyelitis. Bone scans have the ability to detect osteomyelitis far in advance of the standard radiograph. The sequential use of technetium and gallium has been useful in differentiating cellulitis and osteomyelitis. Serial scanning with technetium and gallium may be used to monitor the response of osteomyelitis to antibiotic therapy.

A Case of Community-Associated Methicillin-Resistant Staphylococcus Aureus Infections in a Community Hospital  

PubMed Central

Infections caused by methicillin-resistant Staphylococcus Aureus (MRSA) have recently occurred in communities in people lacking known healthcare risk factors. This MRSA infection is referred to as community-associated MRSA (CA-MRSA) infection, and is distinct from hospital-associated MRSA infection, which occurs in people with risk factors. We experienced a patient diagnosed with CA-MRSA cellulitis, as culture of pus revealed MRSA and he had not been exposed to healthcare environments for the past year. The patient was a previously healthy 38-year-old man with suppurative cellulitis in his right index finger following injury to the finger at his worksite. The cellulitis was successfully managed with incision and drainage (I&D), followed by cefazolin during a 10-day clinical course, although the patient’s MRSA strain was resistant to cefazolin. There are several reports that suggest that I&D followed by antibiotic treatment for CA-MRSA skin infection produces equivalent clinical outcomes, whether the antibiotic prescribed was effective or not. Given that MRSA emerged in an outpatient setting, CA-MRSA should be considered a possible etiology of skin infection in healthy individuals with no classical risk factors for acquisition of MRSA.

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

PubMed Central

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 took place prior to research support being available through the Comprehensive Clinical Research Network (CCRN). There is a balance to be struck between asking a lot of centres to recruit just a few patients, and asking a few centres to recruit a lot of patients. Giving modest funds to principal investigators to buy local research nurse time did not work well, probably because too little research time was bought, and it was difficult to separate research tasks from the nurses existing clinical duties. National research infrastructure networks such as the Comprehensive Clinical Research Network will overcome many of the problems encountered in the PATCH II trial. Trial Registration The trial registration number is ISRCTN03813200. PMID:20196846

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

PubMed Central

Background: 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. Objective: The aim was to compare the diagnostic accuracies of three phase bone scan (TPBS) and FDG PET-CT (FDG-PET) in diabetic foot evaluation. Methods: 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. Conclusion: Flourodeoxy glucose PET-CT has a higher specificity and NPV than TPBS in diagnosing pedal osteomyelitis.

Emergency imaging assessment of deep neck space infections.  

PubMed

Deep neck space infection may lead to severe and potentially life-threatening complications, such as airway obstruction, mediastinitis, septic embolization, dural sinus thrombosis, and intracranial abscess. The clinical presentation is widely variable, and often early symptoms do not reflect the disease severity. The complication risk depends on the extent and anatomical site: diseases that transgress fascial boundaries and spread along vertically oriented spaces (parapharyngeal, retropharyngeal, and paravertebral space) have a higher risk of complications and require a more aggressive treatment compared with those confined within a nonvertically oriented space (peritonsillar, sublingual, submandibular, parotid, and masticator space). Imaging has 5 crucial roles: (1) confirm the suspected clinical diagnosis, (2) define the precise extent of the disease, (3) identify complications, (4) distinguish between drainable abscesses and cellulitis, and (5) monitor deep neck space infection progression. Ultrasonography is the gold standard to differentiate abscesses from cellulitis, for the diagnosis of lymphadenitis. and to identify internal jugular thrombophlebitis in the infrahyoid neck. However, field-of-view limitation and poor anatomical information confine the use of ultrasonography to the evaluation of superficial lesions and to image-guided aspiration or drainage. Computed tomography (CT) combines fast image acquisition and precise anatomical information without field-of-view limitations. For these reasons, it is the most reliable technique for the evaluation of deep and multicompartment lesions and for the identification of mediastinal and intracranial complications. Contrast agent administration enhances the capability to differentiate fluid collections from cellulitis and allows the detection of vascular complications. Magnetic resonance imaging is more time-consuming than CT, limiting its use to selected indications. It is the technique of choice for assessing the epidural space involvement in pre- and paravertebral space infections and complements CT in the evaluation of the infections reaching the skull base.

Three phase bone scan interpretation based upon vascular endothelial response  

PubMed Central

Objectives: A new method of interpretation of Three Phase Bone Scan (TPBS) scan based upon the normal physiological vascular endothelial related response. Materials and Methods: Fifty cases of TPBS were evaluated. Thirteen were normal. In remaining 37 positive studies, 20 showed localized hyperemic response. All localized hyperemic responses except one with vascular endothelial dysfunction were without infection (95.0%). Infection could be ruled out in absence of generalized massive flow and pool response. All 17 cases with generalized massive hyperemic response had infection, consistent with infection or CRPS/RSD. Micro-bacterial or histological confirmation of infection was obtained in 11 cases. All 11 cases with confirmed infection showed generalized massive hyperemic response (100.0%). Two were CRPS/RSD and 2 cases were of cellulitis (100.0%). Among remaining 2, one refused surgery and other was lost to follow-up. Additionally, 20 published cases in the literature of osteomyelitis were also analyzed. Nineteen cases of bone and joint infection, (osteomyelitis/arthritis/cellulitis) except one with endothelial dysfunction showed generalized massive increased flow and pool response (95.0%). All published cases of osteomyelitis in the literature showed generalized massive hyperemic response (100.0%). Results: The data clearly indicated that 100% of the cases of bone infection (osteomyelitis/arthritis/cellulitis) and cases of CRPS/RSD showed generalized massive flow and pool pattern. Infection could be ruled out in absence of generalized massive flow and pool response. All 100% published cases of osteomyelitis in the literature showed positive vascular endothelial response. Conclusion: By incorporating the concept of vascular endothelial related response causing massive vasodilatation in infection, the interpretation of the TPBS can be more précised as it is based upon the normal physiology. Larger studies are recommended.

Cutaneous furuncular myiasis: Human infestation by the botfly.  

PubMed

Dermatobia hominis, the botfly, is indigenous to Central and South America. Its usual host is a mammal, often a horse or cow. Cutaneous furuncular myiasis, human infestation by the botfly, has rarely been reported. Symptoms of infestation include a locally painful, firm furuncular lesion, often with a centrally located pore. Due to their infrequent occurrence, these lesions are often misdiagnosed as cellulitis, leishmaniasis, furunculosis, staphylococcal boil, insect bite or sebaceous cyst - conditions with similar presentations. The present case reiterates the need to think of 'zebras' when hearing 'hoof beats' that may have originated in a different land. PMID:19554228

Three eyelid localized cutaneous anthrax cases.  

PubMed

Anthrax is primarily seen in the developing countries, but it can be a worldwide medical concern due to bioterrorism threats. Palpebral anthrax is a rare form of cutaneous anthrax. Untreated cutaneous anthrax can be lethal. Patients with palpebral anthrax can develop complications including cicatrisation and ectropion. Thus, anthrax should be considered in differential diagnosis for patients presenting with preseptal cellulitis in high-risk regions. Herein, we report three anthrax cases (with different age) involving eyelids that were cured without any complications due to early diagnosis and treatment. PMID:24641116

Multiple nontuberculous scrofulodermas showing dramatic response to clarithromycin  

PubMed Central

Atypical mycobacteria are distinct from the Mycobacterium tuberculosis. Mycobacterium chelonae, a non-pigment producing rapid grower, can be found in many cutaneous sites; infection occurs most commonly after skin trauma from surgery, injections, or minor injuries. In immune competent patients, the infection is more frequently localized as a cellulitis or a nodule, whereas, in the immunocompromised patient, dissemination (more than five lesions) can occur. Because the organism is resistant to antituberculous therapy, abscess can develop and follow a chronic, indolent course. We report a case of multiple scrofuloderma due to nontuberculous infection caused by M. chelonae showing dramatic response to clarithromycin. PMID:25657914

Bisphosphonate-related osteonecrosis of the jaw complicated by Ludwig's angina.  

PubMed

Ludwig's angina is a life-threatening cellulitis that involves the submandibular and sublingual spaces. It often occurs after an infection of the roots of the teeth. However, modern dental care and use of antibiotics for oral infections have made Ludwig's angina rare. We present here a cancer patient exhibiting the sequential features of bisphosphonate related osteonecrosis of the jaw on bone scan complicating with Ludwig's angina. This report highlights the need for medical practitioners to be alert to these rare combinations in the compromised patient after bisphosphonate therapy. To the best of our knowledge, no case of Ludwig's angina secondary to osteonecrosis of the jaw has been reported. PMID:25074798

Necrotizing fasciitis is an uncommon disease that results in gross morbidity and mortality if not diagnosed and treated in its early stages. At onset, however, it is difficult to differentiate from other superficial skin conditions such as cellulitis. Family physicians must have a high level of suspicion and low threshold for surgical referral when confronted with cases of pain, fever, and erythema. We present ten cases of necrotizing fasciitis managed in a provincial secondary hospital in Oman over 3 years ago. A review of recent literature is also presented. PMID:23904882

Dental procedures done in the vicinity of dermal fillers may result in complications of the dermal fillers such as infections which may mimic a dental infection. These infections of dermal fillers must be differentiated from facial cellulitis or from dental infection as treatment for infection from dermal fillers may be prolonged with repeated use of antibiotics, incision and drainage or removal of the filler material itself. Dental surgeons need to be aware of this potential risk in order to recognize and manage it appropriately. PMID:25838691

Cupriavidus gilardii is a rare cause of human infection. We report a muscular abscess on the right thigh caused by this organism in a renal transplant recipient, who had suffered a septic shock associated with an extensive cellulitis caused by Streptococcus pyogenes. The patient was successfully treated with surgical drainage and intravenous ciprofloxacin for 13 days. This is the first time that C. gilardii is isolated from a human abscess. C. gilardii should be considered as a cause of human infection, especially in immunocompromised patients. Infection caused by this organism may be underdiagnosed because the identification is very difficult. PMID:24582579

Ruptured Popliteal Cyst Diagnosed by Ultrasound Before Evaluation for Deep Vein Thrombosis  

PubMed Central

Most popliteal cysts are asymptomatic. However, cysts may rupture, resulting in pain and swelling of the leg that could also arise from other diseases, including deep vein thrombosis, lymphedema, cellulitis, and tear of a muscle or tendon. Therefore, it is difficult to diagnose a ruptured popliteal cyst based on only a patient's history and physical examination. Musculoskeletal ultrasound has been regarded as a diagnostic tool for ruptured popliteal cyst. Here, we describe a patient who was rapidly diagnosed as ruptured popliteal cyst by ultrasonography. Therefore, ultrasound could be used to distinguish a ruptured popliteal cyst from other diseases in patients with painful swollen legs before evaluation for deep vein thrombosis. PMID:25566485

[Orbital complications of sinusitis].  

PubMed

Orbital complications categorised by Chandler are emergency. They need early diagnosis and agresive treatment. Stage and origin of orbital complications are identified by rhinoendoscopy, ophtalmologic examination and CT of orbite and paranasal sinuses. Periorbital cellulitis and early stage of orbital cellulitis can be treated conservatively with i. v. antibiotics. Monitoring of laboratory parameters and ophtalmologic symptoms is mandatory. Lack of improvement or worsening of symptoms within 24-48 hours and advanced stages of orbital complications are indicated for surgery. The purpose of the study is to evaluate epidemiology, clinical features and management of sinogenic orbital complications. Retrospective data of 8 patients with suspicion of orbital complication admited to hospital from 2008 to 2013 were evaluated. Patients were analyzed in terms of gender, age, CT findings, microbiology, clinical features, stage and treatment. Male and female were afected in rate 1,66:1. Most of patients were young adult in 3rd. and 4th. decade of life (62,5 %). Acute and chronic sinusitis were cause of orbital complication in the same rate. The most common origin of orbital complication was ethmoiditis (62,5 %), than maxillary (25 %) and frontal (12,5 %) sinusitis. Polysinusitis with affection of ethmoidal, maxillary and frontal sinuses (75 %) was usual CT finding. Staphylococcus epidermidis and Staphylococcus aureus were etiological agens in half of cases. Periorbital oedema (100 %), proptosis, chemosis (50 %), diplopia and glaucoma (12,5 %) were observed. Based on examinations, diagnosis of periorbital oedema/preseptal cellulitis was made in 3 (37,5 %), orbital cellulitis in 3 (37,5 %) and subperiosteal abscess in 2 cases (25 %). All patients underwent combined therapy - i. v. antibiotics and surgery within 24 hours. Eradication of disease from ostiomeatal complex (OMC), drainage of affected sinuses and drainage of subperiosteal abscess were done via fuctional endonasal endoscopic surgery (FEES). In case of superior subperiosteal abscess, combined endonasal and external approach (external orbitotomy) was needed. Combined therapy facilitated quick improvement of local and systematic symptoms. Average time of hospitalisation was 7 days. Early diagnosis and agresive combined therapy prevent loss of vision and life threatening complications. PMID:25640234

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. PMID:25580339

Fatal septicemia caused by Helicobacter infection in a pancake tortoise (Malacochersus tornieri).  

PubMed

Bacteria of the genus Helicobacter are associated with disease in humans and animals. Reports of infection in reptiles are very limited. In the present study, pathological findings and molecular characterization are reported for a Helicobacter species associated with septicemia in a pancake tortoise (Malacochersus tornieri). Disseminated infection resulted in regional cellulitis and edema of the head and neck, and pericarditis. Spiral bacteria were identified in cytological preparations and Warthin-Starry-stained sections of pathological lesions. Amplification of partial sequence of the 16S ribosomal gene using polymerase chain reaction identified the organism as Helicobacter and suggest that it is a novel species. PMID:20622247

Ultrasonography was performed on 54 patients with lesions of the extremities and pelvic girdle. Computed tomography (CT) was employed in 8 patients. Focal space-occupying lesions such as tumors, abscesses, hematomas, aneurysms, and popliteal cysts (dissecting or otherwise) were delineated by ultrasound and their extent defined. Differentiation from diffuse changes such as lymphedema, cellulitis, or phlebitis and diagnosis of aneurysms were possible. Popliteal cysts were ususally quite characteristic, while correlation with the clinical features suggested the correct diagnosis in the case of the other lesions. CT correlated well with ultrasound, except for one tumor of the forearm which was not shown by CT.

The febrile child with a painful bone or joint still presents a difficult pediatric diagnostic problem. Acute hematogenous osteomyelitis, septic arthritis, and cellulitis are the most common causes of this symptom. Thirty-seven patients with these disorders were studied. Because findings from technetium-99m phosphate bone scans and roentgenograms are often normal in patients in the early stages of acute hematogenous osteomyelitis, children suspected of having this disorder were tested using gallium-67 citrate scans in addition to the other diagnostic procedures. The increased diagnostic accuracy of this approach over that of bone scan and roentgenogram studies alone was observed in the children with fever and bone or joint pain.

When bone scanning agents are combined with bone marrow scanning agents and gallium-67 scintigraphy, a more accurate diagnosis can be obtained. By selecting the appropriate imaging sequence, it is often possible to distinguish cellulitis from underlying osteomyelitis. In patients with total hip replacements, it may be possible to separate postsurgical changes from prosthetic loosening or infection.

Twenty-four patients with inflammatory lesions of the abdominal wall were examined by ultrasonography. Nine of these patients underwent computed tomographic (CT) scanning as well. Both ultrasonography and CT clearly delineated the exact location and extent of abdominal wall abscesses. Abscesses were easily differentiated from cellulitis or phlegmon with ultrasound. The peritoneal line was more clearly delineated on ultrasonograms than on CT scans; abscesses were also more distinct on the ultrasonograms because of their low echogenicity compared with the surrounding structures. Gas bubbles, fat density with specific low attenuation values, and underlying inflamed bowel loops in obese patients with Crohn's disease were better delineated by CT.

Computed tomography (CT) is now used extensively for the evaluation of orbital, facial, and intracranial infections. Nine patients are presented to illustrate the importance of detecting underlying and unsuspected sinusitis. Prompt treatment of the sinusitis is essential to minimize the morbidity and mortality associated with complications such as brain abscess, meningitis, orbital cellulitis, and osteomyelitis. A review of the literature documents the persistence of these complications despite the widespread use of antibiotic therapy. Recognition of the underlying sinusitis is now possible with CT if the region of the sinuses is included and bone-window settings are used during the examination of patients with orbital and intracranial infection.

Background Anthrax is a zoonotic disease caused by Bacillus anthracis. Naturally occurring human infection is rare and is generally the result of contact with anthrax-infected animals or animal products. Case presentation We examined three patients who had contact with presumed anthrax-infected animal and/or its product and presented with preseptal cellulitis with a localized itchy erythematous papule of the eyelid and non-pitting periorbital edema, followed by ulceration and dark eschar formation. All the three patients responded to intravenous antibiotics, and the lesion resolved leaving scars which caused cicatricial ectropion in all cases. Conclusion Anthrax is a rare disease but should be considered in the differential diagnosis of ulcerative (and eschar forming) preseptal cellulitis with a history of contact with anthrax-infected animals or animal products. Furthermore, cicatrization of the eyelids, one of the sequelae of periocular cutaneous anthrax, should be addressed. Urgent case report to the local zoonotic disease and infection control body and other responsible authorities is recommended. PMID:23924443

Bilateral orbital complications of paediatric rhinosinusitis  

PubMed Central

Background The spread of infection from the ethmoid sinuses to the orbit occurs directly through a congenital dehiscence of the lamina papyracea or via haematogenous spread through ophthalmic venous system. Hence orbital complications of paediatric rhinosinusitis are usually unilateral at presentation. Methods We describe three children with bilateral orbital cellulitis that occurred as a complication of rhinosinusitis without intracranial spread of the infection. The children ranged in the age group from 4 to 7 years. All these children had a prolonged hospital stay from 14 to 25 days and underwent multiple surgical procedures to drain the subperiosteal abscess. These children presented to the hospital with bilateral orbital cellulitis without significant past history. All of them on radiological evaluation showed subperiosteal abscess involving only one orbit. They were taken up for functional endoscopic sinus surgery and the subperiosteal abscess was drained endoscopically with partial removal of lamina papyracea. One case required second surgery despite good recovery for two days post first surgery. Result and conclusion Two cases had severe unilateral visual loss at presentation but both recovered dramatically after the surgery. All cases had uneventful recovery with no residual disability. The purpose of this article is to discuss the reasons for bilateral orbital complications of rhinosinusitis at initial presentation despite the previous hypothesis of unilateral involvement.

Fine-needle aspiration biopsy in diagnosis of soft tissue infections.  

PubMed Central

This study explores the efficacy of fine-needle tissue aspiration biopsy in the diagnosis of soft tissue infections that cannot be sampled satisfactorily by regular microbiological techniques. Aspiration biopsy was performed on 50 patients with presumptive soft tissue infections. The conditions investigated were decubitus, diabetic, ischemic, venous, and traumatic ulcers (2, 6, 1, 2, and 7 patients, respectively), cellulitis (23 patients), chronic osteomyelitis (5 patients), and infected surgical wounds (4 patients). Where possible, comparison with superficial cultures was made. All of the cultures obtained from aspirate samples taken from ulcers, chronic osteomyelitis, and infected surgical wounds were positive. In cellulitis, cultures from aspirates were positive in 30 and 81% of the cases, respectively, depending on the presence or absence of concomitant antimicrobial therapy. These results suggest that fine-needle deep tissue aspiration biopsy is reliable and clinically applicable for deep tissue sample collection. The procedure is simple, brief, and does not cause significant discomfort to the patient. It also plays an important role in providing a guideline for antimicrobial therapy. PMID:4019745

Métastase vésicale d'un adénocarcinome gastrique en bague à chaton  

PubMed Central

Bien que le cancer primitif de la vessie représente le deuxième cancer urologique après le cancer de la prostate, les métastases vésicales sont rares et le primitif gastrique reste exceptionnel. On rapporte le cas d'un patient âgé de 46 ans, avec des épigatsralgies chroniques, qui présentait une hématurie totale avec des signes irritatifs urinaires. La cystoscopie a montré une vessie inflammatoire sans lésion tumorale décelable. La biopsie vésicale avec une étude anatomopathologique a été en faveur d'un adénocarcinome peu différencié à cellules indépendantes. Le scanner thoraco-abdomino-pelvien a montré un épaississement vésical et gastrique. La fibroscopie oeso-gastroduodénale a montré une tumeur bourgeonnante ulcérée fundique qui a été biopsiée. L’étude anatomo-pathologique a montré un adénocarcinome gastrique à cellules indépendantes mucipares. Le patient a eu 6 cures de chimiothérapie palliative de première ligne type EOX à base d'Epirubicine, Oxaliplatine, et Capécitabine, avec une légère régression tumorale puis une chimiothérapie de maintenance à base de Capécitabine.

Evaluation of extremity pain in children using technetium-99m MDP bone scan: A general hospital experience  

SciTech Connect

This study was undertaken to evaluate the efficacy of three-phase bone scan in detection of significant pathology i.e., osteomyelitis (OM), septic joint, cellulitis, etc., in children with symptoms of extremity pain. A total of 100 consecutive patients (age 9 days - 16 yrs, 63 boys and 37 girls) were studied. The authors reviewed their scans, x-rays and hospital records. The final diagnoses were based on the findings of needle aspiration, surgical drainage, biopsy, culture, and on the therapeutic response. In 87%, sufficiently long clinical follow-up was available to confirm the final diagnoses. In the remaining 13%, the symptoms resolved quickly and follow-up was not felt necessary. The scan was essential in pinpointing the lesions in pts with referred or nonlocalizing extremity pain. The +ve and -ve predictive values of the scan and OM were 89% and 96% respectively. One spiral fracture was misinterpreted as diffuse OM. One ''Subacute epiphyseal OM'' was not detected. In two cases, cellulitis and septic joint obscured underlying OM. Prior antibotic therapy resulted in one equivocal scan. Although less sensitive (29%) in early OM, radiographs play an important complimentary role. Bone scans detected underlying pathology for extremity pain in 61% of all pts studied.

Validation of a disease model in Japanese quail (Coturnix coturnix japonica) with the use of Escherichia coli serogroup O2 isolated from a turkey  

PubMed Central

This study established a disease model and protocol for bacterial challenge with Escherichia coli serogroup O2 strain EC317 in Japanese quail. Five groups of 10 birds each were injected subcutaneously in the breast with 200 ?L of a brain–heart infusion (BHI) culture containing 1 × 108, 1 × 107, 1 × 106, 1 × 105, or 1 × 104 colony-forming units/mL of the test organism, which had been isolated from a turkey with cellulitis and septicemia. Birds in a 6th group were controls that received sterile BHI alone. Localized lesions of cellulitis developed in all of the birds that received E. coli. The morbidity and mortality rates were highest (100%) in the birds receiving the highest dose of E. coli and decreased linearly with decreasing dose (P < 0.05). Severity of disease, including lesions of pericarditis and perihepatitis, was also directly proportional to the dose of E. coli. These findings indicate that this disease challenge protocol can be used to study disease resistance and immunologic consequences of contaminant exposure or other stressors in birds. PMID:22210992

Rare complication of silicone fluid injection presenting as multiple calcification and skin defect in both legs: a case report.  

PubMed

In the past, many materials have been injected for soft tissue augmentation including paraffin (mineral oil) and other non-biocompatible products. Liquid silicone as one of these materials has a long and notorious history as an injectable material for soft tissue augmentation. However, complications, including cellulitis, ulcerations, migration, and nodule formation, have also been reported with silicone injections. This article aims to demonstrate the diagnosis and treatment of multiple calcification and skin defect after silicone fluid injection for soft tissue augmentation. A 65-year-old female presented with skin defect and calcifications had been steadily increasing in size over a 3-month period. Examination confirmed pain, swelling, induration, and 5 × 5 cm sized skin defect with marginal and adjacent calcification in the left lateral malleolar area. She had been injected silicone fluid for soft tissue of lower extremity augmentation and contouring 30 years ago. Serial surgical debridement of this entire zone of calcification and ulceration was undertaken. The defect was closed by a split thickness skin graft. She was satisfied with the aesthetic appearance of the lateral malleolar area, relieving the symptoms of cellulitis. PMID:25564484

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

PubMed Central

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

Safety and tolerability of denosumab for the treatment of postmenopausal osteoporosis  

PubMed Central

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. PMID:22279412

Importance des communications intercellulaires en radiopathologie expérimentale : le syndrôme inflammatoire radioinduit  

NASA Astrophysics Data System (ADS)

The monolithic image of radiation pathology, the physiopathological mechanisms of which are limited to the conventional concept of specific “target cell" with mitotic and apoptotic cell death, is changing owing to our increasing knowledge about intercellular communications. The cellular radiationbiology is currently enriched by the “humoral" radiationbiology with its concept of “target network" including cells and intercellular messengers. The radiation-induced disorders observed in these networks take shape in the inflammatory reaction, which is largely involved, in the physiopathological development of the acute radiation syndrome. These concepts of a perpetual cascade of cytokines, leading to radiation-induced late effects with no biological latent period, are especially illustrated by the radiation-induced pneumonitis and pulmonary fibrosis. L'image monolithique de la radiopathologie dont les mécanismes physiopathologiques sont réduits aux concepts classiques de “cellule cible" spécifique avec mort cellulaire mitotique et apoptotique, se modifie grâce à l'accroissement de nos connaissances sur les communications intercellulaires. La radiobiologie cellulaire s'enrichit aujourd'hui de la radiobiologie “humorale" avec son concept de “réseau cible" tant au niveau des cellules que des messagers intercellulaires. Les désordres radio-induits observés au niveau de ces réseaux se concrétisent dans la réaction inflammatoire qui est fortement impliquée dans l'évolution physiopathologique du syndrome aigu d'irradiation. Ces concepts d'une cascade perpétuelle de cytokines, sans période de latence biologique et qui amènent aux effets tardifs radio-induits, sont particulièrement illustrés dans la pneumonie et la fibrose pulmonaire radio-induites.

A triangulation of $\\CC P^3$ as symmetric cube of $S^2$  

E-print Network

The symmetric group $S_3$ acts on $S^2 \\times S^2 \\times S^2$ by coordinate permutation, and the quotient space $(S^2 \\times S^2 \\times S^2)/S_3$ is homeomorphic to the complex projective space $\\CC P^3$. In this paper, we construct an 124-vertex simplicial subdivision $(S^2 \\times S^2 \\times S^2)_{124}$ of the 64-vertex standard cellulation $S^2_4 \\times S^2_4 \\times S^2_4$ of $S^2 \\times S^2 \\times S^2$, such that the $S_3$-action on this cellulation naturally extends to an action on $(S^2 \\times S^2 \\times S^2)_{124}$. Further, the $S_3$-action on $(S^2 \\times S^2 \\times S^2)_{124}$ is "good", so that the quotient simplicial complex $(S^2 \\times S^2 \\times S^2)_{124}/S_3$ is a 30-vertex triangulation $\\CC P^3_{30}$ of $\\CC P^3$. In other words, we construct a simplicial realization $(S^2 \\times S^2 \\times S^2)_{124} \\to \\CC P^3_{30}$ of the branched covering $S^2 \\times S^2 \\times S^2 \\to \\CC P^3$.

Croissance epitaxiale de GaAs sur substrats de Ge par epitaxie par faisceaux chimiques  

NASA Astrophysics Data System (ADS)

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). Les experiences ont permis de confirmer l'efficacite du procede de preparation de surface et d'identifier les conditions de croissance optimales. Les resultats de caracterisation indiquent que les materiaux obtenus presentent une tres faible rugosite de surface, une bonne qualite cristalline et un dopage residuel relativement important. De plus, l'interface GaAs/Ge possede une faible densite de defauts. Finalement, la diffusion d'arsenic dans le substrat de germanium est comparable aux valeurs trouvees dans la litterature pour la croissance a basse temperature avec les autres procedes d'epitaxie courants. Ces resultats confirment que la technique d'epitaxie par faisceaux chimiques (CBE) permet de produire des couches de GaAs sur Ge de qualite adequate pour la fabrication de cellules solaires a haute performance. L'apport a la communaute scientifique a ete maximise par le biais de la redaction d'un article soumis a la revue Journal of Crystal Growth et la presentation des travaux a la conference Photovoltaics Canada 2010 .

From ophthalmologist to dentist via radiology  

PubMed Central

Summary Background: 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. Material/Methods: 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. Results: Iatrogenic treatment was the cause of sinusitis and cellulitis in three cases: incorrectly implanted dental implant in one case, root of the 3rd 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. Conclusions: Co-operation between ophthalmologists, radiologists and dentists is necessary during the treatment of such orbital diseases. PMID:22802862

Pseudomonas aeruginosa ecthyma gangrenosum in a woman with recurrent Graves' disease.  

PubMed

A 35-year-old woman with postoperative recurrent Graves' disease presented with a 5-day history of a red swelling on the right cheek associated with 4 days of remittent hyperpyrexia. Investigations revealed fever, a gangrenous ulcer on the right cheek, submandibular lymphadenopathy, and thyroid gland enlargement. Her white blood cell count, immunoglobulins, and lymphocyte subsets were unremarkable. Thyroid function tests showed low thyroid-stimulating hormone, high free thyroxine, and elevated radioactive iodine uptake. Repeated pus cultures grew Pseudomonas aeruginosa, but blood cultures were negative. An ill-demarcated erythematous plaque occurred on the right leg on hospital day 3. She was treated with intravenous antibiotics with topical gentamicin, recombinant bovine basic fibroblast growth factor, and radioiodine therapy with anti-thyroid drugs. The ulcer healed leaving a depressed scar at 35 days after discharge. This patient may represent the first case of P. aeruginosa ecthyma gangrenosum and cellulitis in postoperative recurrent Graves' disease. PMID:24560831

The retina was one of the main objects of study in the first stage of the scientific work of Ramón y Cajal. As culmination of his previous works Cajal published in 1893 in the journal La Cellule an article titled "La rétine des Vertébrés". This article on the retina is a perfect example of Cajal's ability for the systematic study of the cellular types of the nervous centers, its morphological description and its intercellular contacts, as well as for the formulation of physiological interpretations and hypothesis on the development of the neuronal prolongations. Finally some comments are made on the influence of the evolutionary thinking of Haeckel and Herbert Spencer on the work of Ramón y Cajal. PMID:11640477

Hand infections: anatomy, types and spread of infection, imaging findings, and treatment options.  

PubMed

Infections of the hand are common, particularly in immunocompromised patients, and can lead to significant morbidity, including amputation, if not treated properly. Hand infection can spread far and wide from the original site of inoculation through interconnections between the synovium-lined and nonsynovial potential spaces. Because surgery is the mainstay of treatment, knowledge of the pertinent anatomy is imperative for accurately describing the presence, location, and extent of infection. The authors review the pertinent anatomy of the spaces of the hand and describe different types of infection-including cellulitis, necrotizing fasciitis, paronychia, felon, pyogenic flexor tenosynovitis, deep space infections, septic arthritis, and osteomyelitis-and common causative organisms of these infections. They also describe various modes of spread; the common radiologic appearances of hand infections, with emphasis on findings at magnetic resonance imaging and ultrasonography; and the role of radiology in the management of these infections, along with a brief overview of treatment options.

Postoperative erosions of the Mersilene® suburethral sling mesh for antiincontinence surgery  

PubMed Central

The objective of the study was to describe the presentation of vaginal mesh erosions following Mersilene® suburethral slings for urinary incontinence. We performed a retrospective review of all Mersilene® suburethral slings placed at a tertiary referral center from 1996 to 2007. A total of 772 women underwent placement of a Mersilene® suburethral sling. We identified 62 women that underwent surgical revision due to mesh erosion for an overall erosion rate of 8%. The most common presenting symptom was vaginal discharge reported in 37% of women. Other symptoms included vaginal bleeding in 31%, pain or dyspareunia in 13%, and voiding dysfunction in 21% of women. Seven women were found to have the mesh in the bladder on cystoscopy. Cellulitis complicated 8.3% of erosions. Patients with erosions of Mersilene® mesh slings commonly complain of vaginal bleeding and discharge and may present up to 20 years after the surgery.

Upper body pain and functional disorders in patients with breast cancer.  

PubMed

Upper body pain and dysfunction are common in survivors of breast cancer. Disorders of the upper body can result directly from breast cancer or from the surgery, chemotherapy, radiotherapy, or hormonal therapies used in its treatment. Although considerable information is available regarding impairments such as pain and restricted shoulder range of motion associated with breast cancer and its treatment, relatively little information is available about the specific neuromuscular, musculoskeletal, lymphovascular, and other diagnostic entities that underlie those impairments. This article will detail the common and specific causes of upper body pain and dysfunction in breast cancer survivors, including postsurgical pain, rotator cuff disease, adhesive capsulitis, arthralgias, cervical radiculopathy, brachial plexopathy, mononeuropathy, postmastectomy pain syndrome, lymphedema, axillary web syndrome, deep vein thrombosis, and cellulitis. Diagnostic specificity is a key first step to safely and effectively restore function and quality of life to breast cancer survivors. PMID:24360839

Bordetella holmesii meningitis in an asplenic patient with systemic lupus erythematosus.  

PubMed

Bordetella holmesii is a slow-growing, Gram-negative, non-oxidizing bacillus with colonies that produce a brown soluble pigment and was originally described by Weyant et al. (1995) as CDC nonoxidizer group 2 (NO-2). It has recently been shown that B. holmesii may be isolated from nasopharyngeal specimens of up to 20% of patients with pertussis-like symptoms. However, invasive B. holmesii has rarely been reported and in the vast majority of cases the patients were immune deficient, mostly as a result of splenectomy or functional asplenia. Clinical presentations have included endocarditis, pneumonia, cellulitis, suppurative arthritis, pyelonephritis and septicaemia but no previous reports have documented meningitis secondary to this organism. Here we report what we believe to be the first clinical description of an adult with B. holmesii meningitis and bacteraemia with a brief review of published cases. PMID:22556329

Antimicrobial Prophylaxis in Adults  

PubMed Central

Antimicrobial prophylaxis is commonly used by clinicians for the prevention of numerous infectious diseases, including herpes simplex infection, rheumatic fever, recurrent cellulitis, meningococcal disease, recurrent uncomplicated urinary tract infections in women, spontaneous bacterial peritonitis in patients with cirrhosis, influenza, infective endocarditis, pertussis, and acute necrotizing pancreatitis, as well as infections associated with open fractures, recent prosthetic joint placement, and bite wounds. Perioperative antimicrobial prophylaxis is recommended for various surgical procedures to prevent surgical site infections. Optimal antimicrobial agents for prophylaxis should be bactericidal, nontoxic, inexpensive, and active against the typical pathogens that can cause surgical site infection postoperatively. To maximize its effectiveness, intravenous perioperative prophylaxis should be administered within 30 to 60 minutes before the surgical incision. Antimicrobial prophylaxis should be of short duration to decrease toxicity and antimicrobial resistance and to reduce cost. PMID:21719623

[Septic shock by Vibrio vulnificus at the coast Gulf of Mexico].  

PubMed

Vibrio vulnificus is a Gram-negative bacterium which is found in marine environments and where there is a partly enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the open sea. The infection by these bacteria can cause primary septicemia by two mechanisms: upon consuming crustaceans, mollusks and some fish (filtering shellfish) raw or barely cooked or by an open injury in contact with seawater. The patients with infections of the primary injury by Vibrio vulnificus developed contaminated painful cellulitis that progresses quickly as well as a marked local inflammation with signs of hemorrhaging. We described a case of Vibrio vulnificus sepsis, with emphasis on the clinical picture, the epidemiological background and lab findings; finally we did a brief review of the literature related to the case.

Angiosarcoma Presenting with Minor Erythema and Swelling  

PubMed Central

A 76-year-old man presented with slowly progressive swelling in his forehead and left upper eyelid over the course of three months. CT scanning showed non-specific enhancement of subcutaneous tissues, suggesting a low-grade cellulitis. Poor response to treatment prompted an MRI, which revealed the presence of a soft tissue lesion. Biopsy of this lesion was positive for angiosarcoma. The patient underwent chemotherapy and radiation, but unfortunately succumbed to his malignancy eight months later. This case illustrates a rare example of facial/periorbital angiosarcoma, a benign-appearing but aggressive tumor associated with a high incidence of mortality. A review of the literature and current treatment options are discussed. PMID:23616765

Rhino-cerebral zygomycosis resistant to antimycotic treatment: a case report.  

PubMed

We report a fatal case of a rhino-cerebral zygomycosis, caused by Rhizopus arrhizus (oryzae). The patient was suffering from idiopathic thrombopenic purpura, diagnosed 1 year earlier. He was already treated with methylprednisolone 5 months prior to his admission to the hospital for a loss of vision and pain in the left eye as well as left orbital cellulitis. After an initial empirical treatment with broad spectrum antibiotics and voriconazole (infection of unknown origin), the patient was treated with liposomal amphotericin as soon as a positive fungal culture revealed a zygomycete. Unfortunately, the mould was resistant to amphotericin B (MIC: 16 microg ml(-1)) and probably to posaconazole (MIC: 4 microg ml(-1)), which was co-administrated a few days later. PMID:18498302

Les mécanismes physiopathologiques sont multiples : un état de surcharge hydrique qui dépend du caractère complet ou incomplet de l’obstacle, des anomalies tubulaires (atteinte de la capacité de dilution et de concentration des urines, diminution de la réabsorption du sodium, fuites de potassium, troubles de l’acidification des urines, insensibilité des cellules tubulaires à l’hormone antidiurétique), ainsi que des facteurs biochimiques et immunologiques sont mis en jeu. La levée d’un obstacle nécessite une surveillance clinique et biologique stricte (diurèse horaire, état hémodynamique, état d’hydratation, créatininémie, urémie, ionogramme sanguin). Le traitement a pour but d’éviter les troubles hémodynamiques et métaboliques graves, et repose sur le principe de la compensation des pertes hydroélectrolytiques. PMID:23283096

Understanding and communicating the benefits and risks of denosumab, raloxifene, and teriparatide for the treatment of osteoporosis.  

PubMed

The number needed to treat is a valuable metric to determine the benefit of therapy, but it must be viewed against the respective number needed to harm. Denosumab and teriparatide (TPTD) have proven antifracture efficacy at vertebral and nonvertebral sites, whereas raloxifene has proven antifracture efficacy at the spine only. Denosumab use has been associated with a small, yet statistically significant, increased incidence of eczema and serious cellulitis. Raloxifene use has been associated with statistically significant increases in the risk of venous thromboembolism and possibly deadly stroke, although not an increase in total strokes. No significant, nontransient adverse events have been reported with TPTD use. When used for the treatment of postmenopausal osteoporosis, denosumab, raloxifene, and TPTD all generally have favorable risk-to-benefit profiles, but therapy-specific contraindications necessitate thoughtful consideration of all available clinical information and individualization of treatment decisions.

Orbital inflammatory disease: Pictorial review and differential diagnosis  

PubMed Central

Orbital inflammatory disease (OID) represents a collection of inflammatory conditions affecting the orbit. OID is a diagnosis of exclusion, with the differential diagnosis including infection, systemic inflammatory conditions, and neoplasms, among other conditions. Inflammatory conditions in OID include dacryoadenitis, myositis, cellulitis, optic perineuritis, periscleritis, orbital apicitis, and a focal mass. Sclerosing orbital inflammation is a rare condition with a chronic, indolent course involving dense fibrosis and lymphocytic infiltrate. Previously thought to be along the spectrum of OID, it is now considered a distinct pathologic entity. Imaging plays an important role in elucidating any underlying etiology behind orbital inflammation and is critical for ruling out other conditions prior to a definitive diagnosis of OID. In this review, we will explore the common sites of involvement by OID and discuss differential diagnosis by site and key imaging findings for each condition. PMID:24778772

The necrotizing fasciitis (NF) means a serious infection of the subcutis, the fascia and superficial dermis secondarily. We report the case of a patient with cellulitis NF of the thoracoabdominal wall complicating Dujarier's bandage. It was monobacterial NF caused by ? hemolytic streptococcus, whose development was supported through an appropriate medical and surgical care. The situation mentioned is the occurrence of secondary infection of skin necrosis occurred in the bandage too tight opposite the support zone of the elbow on the trunk. We point out, through this case, the importance of the medicosurgical and also the importance of making any thoracoabdominal bandage, which could lead, if it is tight, a pressure sore can be a door entry for any NF plus a late diagnosis.

Unilateral RS3PE in a Patient of Seronegative Rheumatoid Arthritis  

PubMed Central

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare but well-reported clinical entity. It is classically described as symmetrical involvement of both upper extremities. Asymmetrical involvement had also been reported, but unilateral presentation is very rare. We hereby report a case of unilateral RS3PE in a patient of seronegative rheumatoid arthritis which was initially misdiagnosed as cellulitis and was given high dose antibiotics without any significant improvement. Later a rheumatologic consultation leads to a prompt diagnosis, and treatment with steroids leads to dramatic reversal of symptoms. This case demonstrates the rare presentation of this rare clinical entity and highlights the necessity of awareness regarding unilateral disease to clinicians. PMID:23662237

Pyomyositis after vaginal delivery  

PubMed Central

Pyomyositis is a purulent infection of skeletal muscle that arises from haematogenous spread, usually with abscess formation. It can develop after a transient bacteraemia of any cause. This type of infection has never been reported before in the literature after vaginal delivery. A 34-year-old woman had progressive severe pain in the left buttock and thigh and weakness in the left lower limb day 1 post spontaneous vaginal delivery. MRI showed severe oedema of the left gluteus, iliacus, piriformis and adductor muscles of the left thigh and a small fluid collection at the left hip joint. She was diagnosed with pyomyositis. She had fever of 37.9°C immediately postpartum and her risk factors for bacteraemia were a mild IV cannula-associated cellulitis and labour itself. She required prolonged treatment with antibiotics before significant clinical improvement was noted. PMID:22693277

[The safety of interleukin-1 receptor antagonist (anakinra) in the treatment of rheumatoid arthritis].  

PubMed

The safety profile of interleukin-1 receptor antagonist (anakinra) has been studied with randomised, placebo-controlled trials involving 2932 patients affected by rheumatoid arthritis. The most frequently reported adverse events were represented by injection site reactions (71%) and headache (13.6%). No statistically significant difference in the incidence of infections was observed among the patients treated with the interleukin-1 receptor antagonist and the patients receiving placebo. In particular, the incidence of serious infections was 1,8% in rheumatoid arthritis patients on anakinra therapy and 0,7% in patients on placebo. The reported serious infections consisted of pneumonia, cellulitis, bone and joint infections, bursitis. No case of opportunistic infections or tubercolosis was observed. The results of clinical studies suggest that anakinra is a new well-tolerated drug for the treatment of patients affected by rheumatoid arthritis. PMID:15201943

Cancer métaplasique du sein: à propos d'un cas  

PubMed Central

Les carcinomes métaplasiques du sein sont des tumeurs rares. Ils constituent un groupe hétérogène de tumeurs définis selon l'organisation mondiale de la santé comme étant un carcinome canalaire infiltrant mais comportant des zones de remaniements métaplasiques (de type épidermoïde, à cellules fusiformes, chondroïde et osseux ou mixte), qui varient de quelques foyers microscopiques à un remplacement glandulaire complet. Les aspects cliniques et radiologiques ne sont pas spécifiques. Le traitement associe la chirurgie, la radiothérapie et la chimiothérapie. L'hormonothérapie n'a pas de place. Le pronostic est sombre. L'histopathologie combinée à l'immunohistochimie permet de poser un diagnostic sure. Etant donné que la prise en charge thérapeutique est limitée, une nouvelle approche moléculaire pourrait modifier cette contribution faible et mal cernée des traitements systémiques classiques. Les patientes atteintes de carcinome métaplasique mammaire pourraient bénéficier de traitements ciblés, ce qui reste à confirmer par des essais cliniques.

Wound infection in the obese pregnant woman.  

PubMed

Obesity has been linked as a risk factor for wound complications and is becoming a more common occurrence. We reviewed the risk factors, preventive strategies, and recommended management of wound complications in obese women undergoing cesarean delivery. The limited available data support the use of prophylactic antibiotic before cesarean delivery, closure of subcutaneous space >2 cm, and maintaining normothermia intraoperatively to help reduce the incidence of postoperative wound complications. Data regarding management of cesarean wound complications in the obese patient are sparse, but they do suggest either primary or secondary closure of wounds is preferred to healing by secondary intention. Antibiotics should be administered in the presence of cellulitis or systemic toxicity. Use of vacuum-assisted wound closure devices may be useful in wound management. There is a need for randomized controlled trials which evaluate the prevention and management of wound complications in obese women undergoing cesarean delivery. PMID:22108085

Metabolic pathways implied in the synthesis of succinoglycan produced by the Su47 strain of R. meliloti were evaluated by 13C-NMR spectroscopy after incubation with [1{-}13C] or [2{-}13C] glucose. The biosynthesis of this polymer by R. meliloti from glucose occurred by a direct polymerisation of the introduced glucose and by the pentose phosphate pathway. Les voies métaboliques impliquées dans la synthèse du succinoglycane produit par la souche Su47 de R. meliloti ont été évaluées par la spectroscopie de RMN du carbone 13 après incubation des cellules avec du [1{-}13C] ou [2{-}13C] glucose. La biosynthèse de ce polymère à partir du glucose se produit par polymérisation directe du glucose et par la voie des pentoses phosphate.

Orbital exenteration under trigeminal block: An innovative method of regional anesthesia  

PubMed Central

Orbital exenteration is a disfiguring operation involving the removal of the entire contents of the orbit, with or without the eyelids. It is widely felt that such extensive surgery can only be performed under general anesthesia. We report our experience with a patient who underwent orbitalexenteration under trigeminal block with intravenous sedation. A 68-year-old male patient was diagnosed to have orbital cellulitis (mucormycosis), uncontrolled diabetes mellitus, ischemic heart disease, dilated cardiomyopathy with severe left ventricular systolic dysfunction with severe pulmonary artery hypertension, and nephropathy. We decided to avoid general anesthesia for such a high-risk patient with many co-morbid illnesses. We gave trigeminal block using a 22-G spinal needle with local anesthetic solution of bupivacaine 0.5% by classic approach. A standard exenteration was performed and the patient tolerated the procedure well with no complications. PMID:24348304

Rhinocerebral mucormycosis in a patient with type 1 diabetes presenting as toothache: a case report from Himalayan region of India.  

PubMed

Mucormycosis is an angioinvasive infection caused by ubiquitous filamentous fungi of the order Mucorales. It is a rapidly progressive fatal infection mostly reported in susceptible individuals, such as those with poorly controlled diabetes or those with defects in phagocytic function. Rhinocerebral mucormycosis is the most common type of mucormycosis in diabetic patients. This case report describes a 17-year-old girl with type 1 diabetes mellitus presenting with rhinocerebral mucormycosis. The patient presented with a history of toothache and facial pain with oedema of left half of face, periorbital oedema and depressed conciousness. She had hyperglycaemia with diabetic ketoacidosis and rapidly developed hemiparesis progressing to quadriparesis and died within 3 days of admission. The current report emphasises the importance of having a high index of suspicion when dealing with patients with diabetes presenting with facial pain or cellulitis and prompt initiation of medical therapy along with surgical debridement for control of rhinocerebral mucormycosis.

Primary cutaneous cryptococcosis treated with debridement and fluconazole monotherapy in an immunosuppressed patient: a case report and review of the literature.  

PubMed

Cryptococcus neoformans is an opportunistic yeast present in the environment. Practitioners are familiar with the presentation and management of the most common manifestation of cryptococcal infection, meningoencephalitis, in patients with AIDS or other conditions of immunocompromise. There is less awareness, however, of uncommon presentations where experience rather than evidence guides therapy. We report a case of primary cutaneous cryptococcosis (PCC) in a patient who had been immunosuppressed by chronic high-dose corticosteroid for the treatment of severe asthma. This case highlights the importance of early recognition of aggressive cellulitis that fails standard empiric antibiotic treatment in an immunocompromised patient. It also demonstrates successful treatment of PCC with a multispecialty approach including local debridement and fluconazole monotherapy. PMID:25722900

Computerized tomography of pelvic osteomyelitis in patients with spinal cord injuries  

SciTech Connect

Computerized tomography (CT) was performed in 19 patients with spinal cord injury (SCI) who had large pressure sores and in whom other complications were suspected. CT detected the depth, extent, and degree of undermining of the edges of the pressure sores in 19 of 27 lesions. Conventional radiography detected four cases of pelvic osteomyelitis. CT detected eight additional cases of pelvic osteomyelitis, as well as eight clinically unsuspected peripelvic and intrapelvic abscesses. Technetium-99m bone scanning was not very helpful because of localization in chronic proliferative changes of bone and widespread foci of myositis ossificans, as well as in osteomyelitis. Gallium-67 scanning detected only one of six abscesses. It was not very helpful because of confusion of abscess and osteomyelitis with intense soft tissue swelling and cellulitis, which are often associated with pressure sores in patients with chronic SCI. CT was found to be, by far, the modality of choice for detection of pelvic osteomyelitis and abscess in patients with SCI.

Experimental infections of the musculoskeletal system: evaluation with MR imaging and Tc-99m MDP and Ga-67 scintigraphy  

SciTech Connect

Acute osteomyelitis, soft-tissue infection, or both were experimentally produced in 38 New Zealand white rabbits, and three-phase technetium-99m methylene diphosphonate, gallium-67, and magnetic resonance (MR) images were obtained 7 or 14 days after infection. There was no significant difference between radionuclide studies and MR images in the detection of osteomyelitis, but MR imaging was significantly more sensitive (100% vs. 69%; P less than .01) in the detection of soft-tissue infection. In addition, cellulitis could not be distinguished from soft-tissue abscess on radionuclide studies, whereas MR imaging was 92% accurate in depicting soft-tissue abscesses. Further research is necessary to determine how to relate these findings to true human clinical situations.

The technetium phosphate bone scan in the diagnosis of osteomyelitis in childhood  

SciTech Connect

We reviewed the technetium phosphate scans of 280 patients who had been referred with a clinical diagnosis of osteomyelitis in order to establish the diagnostic accuracy of this procedure. Strict criteria were established to define two subgroups: one of patients with proved osteomyelitis and one of patients who definitely did not have osteomyelitis. The scan correctly identified osteomyelitis at fifty-five of sixty-two sites, and was correctly negative in seventy-four of seventy-nine patients without osteomyelitis. The scan correctly distinguished all cases of cellulitis or soft-tissue abscess from osteomyelitis, but identified osteomyelitis in eight of thirty-nine patients with septic arthritis. The phosphate bone scan maintained this accuracy through any duration of symptoms, and performed almost equally well at all skeletal sites and in all age groups.

Ludwig's Angina in Pregnancy Necessitating Pre Mature Delivery.  

PubMed

Ludwig's angina is a potentially life threatening disease that can arise from odontogenic infections if they are not attended well in advance. Its incidence in pregnancy is rare, but has been reported. Pregnancy is associated with complex physiological changes in the body which can make small dental infections assume grave proportions if not treated appropriately. This article presents a case of a 24 year old, 32 week pregnant lady who reported with swelling around the jaws and neck, difficulty in breathing and swallowing since 2 days. She had to be taken up for pre-term delivery to avoid damage to foetus. Subsequently she underwent multiple debridement of the cellulitis affecting the deep neck spaces and superior mediastinum. Surgical debridement and intravenous antibiotics along with adequate hydration improved the health of the patient before she was discharged. PMID:25838696

A review of dental treatment of head and neck cancer patients, before, during and after radiotherapy: part 1.  

PubMed

The incidence of head and neck cancer is on the rise. Most head and neck cancers are treated with surgery, radiotherapy, chemotherapy or a combination of these modalities. Patients undergoing radiotherapy can experience several unwanted oral side effects, which have both short and long term implications. Dental general practitioners should be aware of these implications and should liaise closely with the restorative consultants and the oncology team to establish the best oral care pathway. This two-part series is a review of the oral changes that occur during and after radiotherapy and the oral management of head and neck oncology before, during and after radiotherapy. This article deals with both immediate sequelae such as cellulitis, mucositis, dysphagia, dysguesia and weight loss as well as long term sequelae such as rampant caries, trismus, xerostomia and osteoradionecrosis. It also encompasses the importance and need for pre-radiotherapy assessment. PMID:25613260

Chronic osteomyelitis of the clavicle  

SciTech Connect

Osteomyelitis of the clavicle is an uncommon disease, but it should be considered in patients who present with pain, cellulitis, or drainage in the sternoclavicular area following head and neck surgery, irradiation, subclavian vein catheterization, or immunosuppression. An idiopathic presentation is possible. In contrast to primary osteomyelitis of the clavicle, which is occasionally seen in children, secondary osteomyelitis is quite rare. It is often mistaken for a fracture or a possible neoplasm on plain x-rays. Tomograms and CT scanning are confirmatory, and in early cases, technetium-99m bone scanning can be helpful. Treatment must include early, aggressive surgical debridement of all affected tissues, followed by wound coverage with a well-vascularized flap and perioperative antibiotics.

Acute Haemorrhagic Oedema of Infancy (AHOI): A Case Report.  

PubMed

Acute haemorrhagic oedema of infancy (AHOI) is a benign variant of leukocytoclastic vasculitis which occurs in children up to 2 years of age. It is considered by some to be a variant of Henoch-Schönlein purpura with its hallmark of prominent facial swelling, purpuric rash without visceral involvement, in an otherwise well child. This condition is well recognised in the paediatric and dermatology literature but despite its impressive facial features, often mimicking more serious pathology like orbital cellulitis, to our knowledge AHOI has not been published in the Oral & Maxillofacial Surgery literature. We present a case of AHOI to raise awareness of this condition in maxillofacial surgery to avoid it being mis- or over-diagnosed. PMID:25838694

A commercial broiler flock in the Central Valley of California experienced a sudden increase in mortality due to heavy culling. Clinical signs included a snick, swollen heads and severe depression. Necropsy and histology revealed tracheitis, rhinitis, facial cellulitis, blepharitis, episcleritis, otitis media and caseous exudate within the air spaces of cranial bones. Escherichia coli serotype O78 was isolated from all lesions. Infectious bronchitis virus (Massachusetts serotype) was isolated from trachea/nasal cavity tissue pool. Adenovirus group 1 was isolated from trachea/nasal cavity and caecal tonsil tissue pools. Serum samples were positive for infectious bronchitis using ELISA and haemagglutination inhibition tests, but negative for turkey rhinotracheitis by an ELISA using the British antigen. This case suggests that swollen head syndrome can be associated with viruses other than pneumovirus. PMID:18671139

Plates-formes de microscopie et fluorescence par resonance de plasmons de surface appliquees a l'imagerie cellulaire  

NASA Astrophysics Data System (ADS)

L'elaboration de nouveaux medicaments repose sur les etudes pharmacologiques, dont le role est d'identifier de nouveaux composes actifs ou de nouvelles cibles pharmacologiques agissant entre autres au niveau cellulaire. Recemment, la detection basee sur la resonance des plasmons de surface (SPR) a ete appliquee a l'etude de reponses cellulaires. Cette methode de detection, permettant d'observer des variations d'indice de refraction associes a de faibles changements de masse a la surface d'un metal, a l'avantage de permettre l'etude d'une population de cellules vivantes en temps reel, sans necessiter l'introduction d'agents de marquage. Pour effectuer la detection au niveau de cellules individuelles, on peut employer la microscopie SPR, qui consiste a localiser spatialement la detection par un systeme d'imagerie. Cependant, la detection basee sur la SPR est une mesure sans marquage et les signaux mesures sont attribues a une reponse moyennee des differentes sources cellulaires. Afin de mieux comprendre et identifier les composantes cellulaires generant le signal mesure en SPR, il est pertinent de combiner la microscopie SPR avec une modalite complementaire, soit l'imagerie de fluorescence. C'est dans cette problematique que s'insere ce projet de these, consistant a concevoir deux plates-formes distinctes de microscopie SPR et de fluorescence optimisees pour l'etude cellulaire, de sorte a evaluer les possibilites d'integration de ces deux modalites en un seul systeme. Des substrats adaptes pour chaque plate-forme ont ete concus et realises. Ces substrats employaient une couche d'argent passivee par l'ajout d'une mince couche d'or. La stabilite et la biocompatibilite des substrats ont ete validees pour l'etude cellulaire. Deux configurations permettant d'ameliorer la sensibilite en sondant les cellules plus profondement ont ete evaluees, soit l'emploi de plasmons de surface a longue portee et de guides d'onde a gaine metallique. La sensibilite accrue de ces configurations a aussi ete demontree pour un usage en biodetection cellulaire. Une plate-forme permettant de mesurer la spectroscopie SPR simultanement avec l'acquisition d'images de fluorescence a ete realisee. Cette plate-forme a ensuite ete validee par l'etude de reponses cellulaires suite a une stimulation pharmacologique. Puis, un systeme base sur la microscopie SPR a ete concu et caracterise. Son emploi pour l'etude de reponses au niveau de cellules individuelles a ete demontre. Finalement, les forces et faiblesses des substrats et des plates-formes realisees au cours de la these ont ete evaluees. Des possibilites d'amelioration sont mises de l'avant et l'integration des modalites de microscopie SPR et de fluorescence suite aux travaux de la these est discutee. Les realisations au cours de cette etude ont donc permis d'identifier les composantes cellulaires impliquees dans la generation du signal mesure en biodetection SPR. Mots-cles : Resonance des plasmons de surface, microscopie SPR, plasmons de surface a longue portee LRSPR, guide d'onde a gaine metallique MCWG, fluorescence exaltee par plasmons de surface SPEF, biodetection cellulaire, imagerie SPR.

Les carcinomes neuroendocrine primitifs du sein sont des tumeurs rares et représentent 2 à 5% des cancers mammaires. Nous rapportons le cas de localisation mammaire chez une patiente de 50 ans. Il s'agit d'une tumeur classée T4d N1 M0. La tumeur est suspecte radiologiquement. Une microbiopsie est réalisée. L’étude anatomopathologique et immunohistochimique est en faveur d'une tumeur neuroendocrine primitive du sein à grande cellules exprimant les récepteurs progestéroniques seulement. Vu le caractère inflammatoire de la tumeur une chimiothérapie est démarrée avec bonne évolution clinique. A la fin de la chimiothérapie on prévoit de réaliser une mastectomie avec curage axillaire et en fonction des résultats définitifs, une radiothérapie. Une hormonothérapie sera envisagée une 2ème étude immunohistochimique sur la pièce de mastectomie. Vu la rareté des carcinomes neuroendocrines mammaires primitifs, il n'existe pas de standard thérapeutique et le pronostic demeure difficile à déterminer. PMID:24772221

Described here is an unusual case of disseminated Cylindrocarpon lichenicola (Fusarium lichenicola) infection originating from a toenail lesion of a neutropenic woman with cellulitis of the foot and underlying acute leukaemia. A computed tomography scan of the chest showed multiple, ill-defined, nodular infiltrates with alveolar consolidation. The fungus was isolated from both the nail and the skin of the infected toe. Susceptibility testing revealed low minimum inhibitory concentrations for amphotericin B (0.78 micro g/ml) and voriconazole (1.56 micro g/ml) and high minimum inhibitory concentrations (>100 micro g/ml) for fluconazole, ketoconazole and itraconazole. The infection resolved after treatment with a total dose of 1 g of amphotericin B followed by oral itraconazole and bone marrow regeneration. PMID:12582748

Fatal clostridium septicum myonecrosis in a captive canada lynx (Lynx canadensis).  

PubMed

A 1-yr-old female Canada lynx (Lynx canadensis) presented for sudden onset of rapidly progressive bilateral pelvic limb paralysis. The lynx was chemically immobilized to perform a physical examination but expired shortly thereafter. On postmortem radiographs, there were myriad small irregular, round-to-spherical gas densities within the skeletal muscle of the right thigh and epaxial musculature. At gross necropsy, the muscles of the right thigh, right lateral abdominal wall, and epaxial region were emphysematous and necrohemorrhagic, with subcutaneous and muscular crepitant swelling. Multiple skin puncture wounds, consistent with bites, were present over the affected tissues. Clostridium septicum was isolated in pure anaerobic culture from the musculature of the right hind limb. Histopathologic examination confirmed the diagnosis of acute, severe necrohemorrhagic and gangrenous myositis and cellulitis. Gram stains demonstrated large gram-positive bacilli with subterminal spores. This is the first known documented case of C. septicum myonecrosis in a nondomestic felid. PMID:25314833

Some wild plants and their parts are frequently used to treat these diseases. The use of plants is as old as the mankind. Natural treatment is cheap and claimed to be safe. It is also suitable raw material for production of new synthetic agents. A review of some plants for the treatment of skin diseases is provided that summarizes the recent technical advancements that have taken place in this area during the past 17 years. PMID:24600196

Use of the comet assay to measure DNA damage in cells exposed to photosensitizers and gamma radiation  

NASA Astrophysics Data System (ADS)

We used the comet assay associated with DNA-glycosylases to estimate DNA damage in cells exposed to gamma irradiation or photosensitized either with methylene blue or orange acridine. A calibration performed using irradiation allowed the measurement of the steady-state level and the yield of 8-oxodGuo as well as strand breaks and alkali-labile sites. Nous avons utilisé la méthode des comètes associée à des ADN-glycosylases, pour estimer les dommages de l'ADN dans des cellules après l'exposition à un rayonnement gamma ou après photosensibilisation par le bleu de méthylène ou l'acridine orange. Une calibration de la méthode des comètes a permis de mesurer le niveau basal et les taux de formation de 8-oxodGuo ainsi que le nombre de cassures de brins et de sites alcali labiles.

Infectious coryza in meat chickens in the San Joaquin Valley of California.  

PubMed

Two cases of infectious coryza in meat chickens are reported. The first case involved 6-week-old broiler chickens in which only Haemophilus paragallinarum was isolated. The second case involved 11-week-old roaster chickens in which H. paragallinarum and Mycoplasma synoviae were isolated. Both farms were in close proximity to layer-chicken farms where infectious coryza had been previously diagnosed. In both cases, only certain houses on the farm were affected, and mortality in these houses increased slightly. At processing, the condemnation rates for affected houses were considerably higher than rates for unaffected houses. Condemnations for affected houses were mostly due to airsacculitis. A dissecting fibronopurulent cellulitis was a prominent lesion in the second case. This lesion could lead to confusion with chronic fowl cholera and swollen-head syndrome. PMID:2282006

Peritonsillar infection in Christchurch 1981-1984.  

PubMed

Retrospective review of the notes of 83 peritonsillar infection sufferers over three years at Christchurch Hospital reveals that the typical sufferer is a young adult male who is most likely to present in winter or summer. Only a quarter of the patients had a significant recent history of tonsillitis but four had had a previous quinsy and six had had a previous tonsillectomy in childhood. Length of symptoms does not appear helpful in differentiating an abscess from a cellulitis. Anaerobic organisms were found in 49% of aspirates and streptococci were the most important aerobic organism. Potential beta lactamase producing organisms, H influenzae, Staph aureus and Bacteroides sp were infrequent and penicillin remains the drug of choice. Appropriate antibiotics and drainage are the essentials of management and tonsillectomy may be indicated. PMID:3526210

Kawasaki Disease with Retropharyngeal Edema following a Blackfly Bite  

PubMed Central

We describe a patient with Kawasaki disease (KD) and retropharyngeal edema following a blackfly bite. An 8-year-old boy was referred to our hospital because of a 3-day-history of fever and left neck swelling and redness after a blackfly bite. Computed tomography of the neck revealed left cervical lymph nodes swelling with edema, increased density of the adjacent subcutaneous tissue layer, and low density of the retropharyngeum. The patient was initially presumed to have cervical cellulitis, lymphadenitis, and retropharyngeal abscess. He was administered antibiotics intravenously, which did not improve his condition. The patient subsequently exhibited other signs of KD and was diagnosed with KD and retropharyngeal edema. Intravenous immunoglobulin therapy and oral flurbiprofen completely resolved the symptoms and signs. A blackfly bite sometimes incites a systemic reaction in humans due to a hypersensitive reaction to salivary secretions, which may have contributed to the development of KD in our patient.

Elaboration du Ge mesoporeux et etude de ses proprietes physico-chimiques en vue d'applications photovoltaiques  

NASA Astrophysics Data System (ADS)

Le sujet de cette these porte sur l'elaboration du nouveau nanomateriau par la gravure electrochimique bipolaire (BEE) --- le Ge mesoporeux et sur l'analyse de ses proprietes physico-chimiques en vue de son utilisation dans des applications photovoltaiques. La formation du Ge mesoporeux par gravure electrochimique a ete precedemment rapportee dans la litterature. Cependant, le verrou technologique important des procedes de fabrication existants consistait a obtenir des couches epaisses (superieure a 500 nm) du Ge mesoporeux a la morphologie parfaitement controlee. En effet, la caracterisation physico-chimique des couches minces est beaucoup plus compliquee et le nombre de leurs applications possibles est fortement limite. Nous avons developpe un modele electrochimique qui decrit les mecanismes principaux de formation des pores ce qui nous a permis de realiser des structures epaisses du Ge mesoporeux (jusqu'au 10 mum) ayant la porosite ajustable dans une large gamme de 15% a 60%. En plus, la formation des nanostructures poreuses aux morphologies variables et bien controlees est desormais devenue possible. Enfin, la maitrise de tous ces parametres a ouvert la voie extremement prometteuse vers la realisation des structures poreuses a multi-couches a base de Ge pour des nombreuses applications innovantes et multidisciplinaires grace a la flexibilite technologique actuelle atteinte. En particulier, dans le cadre de cette these, les couches du Ge mesoporeux ont ete optimisees dans le but de realiser le procede de transfert de couches minces d'une cellule solaire a triple jonctions via une couche sacrificielle en Ge poreux.

Facteurs influençant l'initiation au traitement antirétroviral des personnes vivant avec le VIH dans les Centres de Traitement Agréés de Bamenda et de Bertoua au Cameroun  

PubMed Central

Introduction L'objectif de ce travail était de déterminer les facteurs influençant l'initiation au traitement antirétroviral des personnes vivant avec le VIH (PVVIH) dans les centres de traitements agrées (CTA) de Bamenda et de Bertoua au Cameroun. Méthodes Il s'agissait d'une étude transversale, analytique réalisée de Janvier à Avril 2011, dans les CTA de Bamenda et de Bertoua. Pour cette étude, nous avons obtenu une clairance éthique. Résultats Nous avons étudiés 460 dossiers de patients séropositifs en phase d'initiation au traitement antirétroviral dans les CTA de Bamenda et de Bertoua, 53,9% et 46,1% respectivement. L ‘âge médian était de 36 ans. La plupart des séropositifs à Bertoua (41) avaient fait un dépistage volontaire du VIH par rapport à ceux de Bamenda (22) (p= 0.008). Il y ‘avait plus de VIH de type 1 et 2 dans le CTA de Bamenda (15) par rapport à Bertoua (3) (p= 0.011). La majorité des patients était classé au stade clinique II à Bamenda (54,0%) tandis qu ‘à Bertoua le stade clinique III était prédominant (52,4%) (p = 0,000). Le taux médian de CD4 était de 133 cellules/mm3 dans le CTA de Bamenda et de 175 cellules/mm3 à Bertoua (p = 0,008). La Zidovudine était plus prescrit à Bamenda et le Ténofovir à Bertoua (p = 0,000). L ‘Efavirenz était plus prescrit à Bertoua tandis que la Névirapine l ‘était plus à Bamenda (p = 0,000). Le Lopinavir/r était plus prescrit à Bamenda qu ‘à Bertoua (p = 0,017). Conclusion Il apparait urgent de standardiser la prise en charge des PVVIH dans les CTA du Cameroun. PMID:25184023

Complicating osteomyelitis imaged with Tc-99m MDP, In-111 granulocytes, and Ga-67 citrate  

SciTech Connect

Gallium-67 and 3-phase bone scan (3P) studies, though very sensitive, are not very specific in evaluating suspected osteomyelitis (OM) which is superimposed upon other diseases that cause increased bone turnover (IBT). The authors compared In-111 acetylacetone labeled granulocytes (In-111) GRAN) with 3P in 57 such patients; 29 of these patients had Ga-67 studies as well. In-111 GRAN had a sensitivity of 100% in acute OM, 62% in chronic OM, and a specificity of 96%. Gallium-67 ruled out OM when the study was normal; it diagnosed OM when the relative uptake of Ga-67 exceeded the uptake of Tc-99m MDP, or when the skeletal distribution of Ga-67 was different from that of the TC-99m MDP. Unfortunately, these criteria were met in only 28% of the subjects. The simple approach of increased Ga-67 activity meant OM gave a sensitivity of 100%, but an unacceptable specificity of 38%. Chronic cellulitis or long-standing decubiti were seldom detected by IN-111 GRAN. Clinically obvious soft tissue infections or cellulitis were seen with In-111 GRAN 27% of the time, and 17% of the time with Ga-67. The authors conclude that when added to 3P, In-111 GRAN provided more useful information than did Ga-67. A combination of all 3 studies did not significantly increase the diagnostic yield. Performing In-111 GRAN without 3P in patients with IBT is not recommended since the 3P provides anatomic information that aids in the differentiation of OM from soft tissue infections.

Mycobacterium fortuitum Infection following Reconstructive Breast Surgery: Differentiation from Classically Described Red Breast Syndrome  

PubMed Central

Background: Red breast syndrome (RBS) has been described as an erythema that may be associated with 2-stage prosthetic reconstructive breast surgery using biologic mesh. RBS is differentiated from infectious cellulitis through absence of fever and laboratory abnormalities and usually has a self-limiting course. There have been no clinical reports on etiology, risk factors, or management of RBS. This report describes patient data that raise the need to rule out mycobacterial infection when RBS is being considered as a diagnosis. Methods: We present 6 cases of Mycobacterium fortuitum infection occurring after prosthetic breast reconstruction performed with a human-derived acellular dermal matrix, including the timing and course of erythema, laboratory results, treatments used, and long-term outcomes. We also describe the differential diagnoses of RBS in the context of these cases, including emergence of acid-fast bacilli and diagnostic and treatment considerations. Exact two-tailed 95% confidence intervals based on the F-distribution are provided with estimates of the incidence rates of infection. Results: The 6 cases presented here do not fit the typical description of RBS and were caused by mycobacterium infection. Statistical evaluation of the estimated incidence rate of M. fortuitum infection in a patient thought to have RBS, which occurred 100% of the time in this series, revealed a 95% confidence interval of 54.1–100%. Conclusions: When presented with possible RBS, surgeons must rule out cellulitis, culture for acid-fast bacilli such as mycobacterium species, and then determine the best course of treatment. Patient counseling regarding potential household sources of infection is warranted to minimize postoperative infection risk. PMID:25289245

Étude des anomalies chromosomiques après radiothérapie chez des patients traités pour lymphome malin non-Hodgkinien  

NASA Astrophysics Data System (ADS)

Structural chromosome defects were evaluated in the lymphocytes of 30 patients (pts) who had undergone radiotherapy for non Hodgkin's lymphoma (NHL). Twelve had received 20 Grays (Gy) over the abdomen (group I), 12 whole body irradiation at 1.5 Gy (group II) and 6 whole body irradiation at 15 Gy (group III). A cohort of 468 unirradiated pts served as controls. For the irradiated group, 7% of cells had aberrations compared to 0.4% in controls {P <10-6}. The frequency of abnormal cells was statistically higher in group I (12%) than in group II (3.5%) and III (2.5%) . In group I, frequency of aberrations was statistically higher in pts who had additionnal extra-abdominal involved field irradiation, those with evolutive NHL and those receiving chemotherapy at the time of the cytogenetic analysis. Les aberrations chromosomiques ont ,été, mesurées sur les lymphocytes de 30 patients (pts) irradiés pour lymphome malin non-hodgkinien (LNH) selon 3 modalités : 20 Grays (Gy) sur l'abdomen (groupe I : 12 pts), Irradiation corporelle totale 1,5 Gy (groupe II : 12 pts), ou 15 Gy (groupe III : 6 pts). Une population non irradiée de 468 pts a servi de témoin. Dans le groupe irradié, 7 % des cellules présentaient des anomalies contre 0,4 % dans le groupe témoin {P <10-6}. Les aberrations ,étaient statistiquement plus nombreuses dans le groupe I (12 % des cellules) que dans les groupes II (3,5 %) et III (2,5 %). Dans le groupe I, les anomalies , étaient statistiquement plus fréquentes chez les pts ayant eu une irradiation localisée extra-abdominale en complément de celle de l'abdomen ainsi que chez ceux en rechute de leur LNH et ceux recevant une chimiothérapie lors de l',étude cytogénétique.

Catfish spine envenomation and bacterial abscess with Proteus and Morganella: a case report  

PubMed Central

Introduction Abscess formation and cellulitis in the setting of envenomation are rare complications of handling catfish. To the best of our knowledge, isolation of Proteus vulgaris has not been previously recorded, and recovery of Morganella morganii has been reported in only one prior case from wound cultures in patients injured by catfish stings. We report a case of catfish envenomation characterized by abscess formation and cellulitis, in which wound cultures grew these unusual organisms. Case presentation A 52-year-old Chinese-American man was hospitalized with erythema and swelling of his right arm of 10?days’ duration after skin penetration by a catfish barb. An abscess of his right thumb had undergone incision and drainage, with purulent drainage sent for wound culture immediately prior to admission. Laboratory studies revealed elevated white blood count, sedimentation rate, and C-reactive protein. The patient was treated with intravenous ampicillin-sulbactam and vancomycin during his hospitalization, and symptoms improved. Wound cultures obtained prior to presentation grew many Proteus vulgaris and Morganella morganii. He was subsequently discharged on a 10-day course of oral ciprofloxacin and amoxicillin-clavulanate. At a 12-month telephone follow-up, the patient denied developing further symptoms and reported that the wound had healed completely without complication. Conclusion Although envenomation and secondary infection are not uncommon sequelae of handling catfish, the present case is unique by virtue of the infecting organisms isolated. Given the prevalence of injury from catfish stings, a review of the literature is presented in order to provide recommendations for prevention and treatment of catfish envenomation. PMID:23631594

Longitudinal Analysis of Methicillin-Resistant and Methicillin-Susceptible Staphylococcus aureus Carriage in Healthy Adolescents  

PubMed Central

To determine the long-term carriage patterns, strain relatedness, and incidence of subsequent infections among methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) carriers, we screened 154 high school students for nasal carriage of S. aureus on 8 occasions over 11 months. Persistent carriage was defined as a positive culture on ?7 occasions. Two consecutive isolates from the same subject comprised a pair, and strain relatedness was determined for each pair by molecular typing. Of 1,232 nasal swab cultures obtained on 8 occasions, 323 (26.2%) were positive for S. aureus. Forty-five isolates (3.7%) were MRSA and 278 isolates (22.6%) were MSSA from 12 and 63 subjects, respectively. Thirty-five (77.8%) MRSA isolates harbored a type IV or VT staphylococcal chromosomal cassette mec element. Among the 154 subjects, 52 (33.8%) were intermittent (1 to 6 positive swabs) carriers. Persistent carriage was identified in 23 (14.9%) subjects, and the incidence was not significantly different for MRSA and MSSA carriers (3/12 [25%] versus 20/63 [31.7%]; P = 0.7449). The MRSA and MSSA isolates were composed of 33 and 215 strain pairs, respectively. Of them, an indistinguishable genotype was identified in 33 (100%) MRSA pairs and 173 (80.5%) MSSA pairs (P = 0.0053). Five subjects developed cellulitis, and the incidence of this was higher for MRSA carriers (2/12 [16.7%]) than for MSSA carriers (1/63 [1.58%]; P = 0.0632) and noncarriers (2/79 [2.56%]; P = 0.0828). In conclusion, the long-term carriage patterns for MRSA and MSSA in healthy individuals were similar. MRSA carriers were more likely to carry a single strain, with a trend toward a higher chance of developing cellulitis than for MSSA carriers. PMID:23678067

Utilisation de l'essai comete et du biomarqueur gamma-H2AX pour detecter les dommages induits a l'ADN cellulaire par le 5-bromodeoxyuridine post-irradiation  

NASA Astrophysics Data System (ADS)

Ce memoire est presente a la Faculte de medecine et des sciences de la sante de l'Universite de Sherbrooke en vue de l'obtention du grade de maitre es sciences (M.Sc.) en radiobiologie (2009). Un jury a revise les informations contenues dans ce memoire. Il etait compose de professeurs de la Faculte de medecine et des sciences de la sante soit : Darel Hunting PhD, directeur de recherche (departement de medecine nucleaire et radiobiologie), Leon Sanche PhD, directeur de recherche (departement de medecine nucleaire et radiobiologie), Richard Wagner PhD, membre du programme (departement de medecine nucleaire et radiobiologie) et Guylain Boissonneault PhD, membre exterieur au programme (departement de biochimie). Le 5-bromodeoxyuridine (BrdU), un analogue halogene de la thymidine reconnu depuis les annees 60 comme etant un excellent radiosensibilisateur. L'hypothese la plus repandue au sujet de l'effet radio sensibilisant du BrdU est qu'il augmente le nombre de cassures simple et double brin lorsqu'il est incorpore dans l'ADN de la cellule et expose aux radiations ionisantes. Toutefois, de nouvelles recherches semblent remettre en question les observations precedentes. Ces dernieres etudes ont confirme que le BrdU est un bon radiosensibilisateur, car il augmente les dommages radio-induits dans l'ADN. Mais, c'est en etant incorpore dans une region simple brin que le BrdU radiosensibilise l'ADN. Ces recherches ont egalement revele pour la premiere fois un nouveau type de dommages produits lors de l'irradiation de l'ADN contenant du BrdU : les dimeres interbrins. Le but de ces travaux de recherche est de determiner si la presence de bromodeoxyuridine dans l'ADN augmente l'induction de bris simple et / ou double brin chez les cellules irradiees en utilisant de nouvelles techniques plus sensibles et specifiques que celles utilisees auparavant. Pour ce faire, les essais cometes et la detection des foci H2AX phosphorylee pourraient permettre d'etablir les effets engendres par le BrdU au niveau cellulaire. Notre hypothese (basee sur des resultats preliminaires effectues dans notre laboratoire) est que l'irradiation de l'ADN cellulaire en presence de BrdU augmentera le nombre de bris simple brin sans toutefois augmenter le nombre de bris double brin. Les resultats presentes dans ce memoire semblent corroborer cette hypothese. Les nouvelles methodes d'analyse, soient l'essai comete et la detection des foci gamma-H2AX remettent en question ce qui a ete dit sur le BrdU au sujet de l'induction des cassures double brin depuis plusieurs annees. L'ensemble de ces nouveaux resultats effectue a l'aide de cellules ayant incorporees du BrdU sont en correlation avec de precedents resultats obtenus dans notre laboratoire sur des oligonucleotides bromes. Ils reaffirment que l'irradiation combinee au BrdU augmente l'induction de bris simple brin mais pas de bris double brin. L'investigation approfondie des mecanismes d'action non elucides du BrdU au niveau cellulaire et son utilisation a des moments strategiques pendant le traitement de radiotherapie pourraient accroitre son efficacite a des fins d'utilisation clinique.

An atlas of the morphological manifestations of hidradenitis suppurativa.  

PubMed

This article is dermatological atlas of the morphologic presentations of Hidradenitis Suppurativa (HS). It includes: superficial abscesses (boils, furnucles, carbuncles), abscesses that are subcutaneous and suprafascial, pyogenic granulomas, cysts, painful erythematous papules and plaques, folliculitis, open ulcerations, chronic sinuses, fistulas, sinus tracts, scrotal and genital lyphedema, dermal contractures, keloids (some that are still pitted with follicular ostia), scarring, skin tags, fibrosis, anal fissures, fistulas (i.e. circinate, linear, arcuate), scarring folliculitis of the buttocks (from mild to cigarette-like scarring), condyloma like lesions in intertrigous areas, fishmouth scars, acne inversa, honey-comb scarring, cribiform scarring, tombstone comedones, and morphia-like plaques. HS can co-exist with other follicular diseases such as pilonidal cysts, dissecting cellulitis, acne conglobata, pyoderma gangrenosum, and acanthosis nigricans. In sum, the variety of presentations of HS as shown by these images supports the supposition that HS is a reaction pattern.HS is a follicular based diseased and its manifestations involve a multitude of follicular pathologies [1,2]. It is also known as acne inversa (AI) because of one manifestation that involves the formation of open comedones on areas besides the face. It is as yet unclear why HS is so protean in its manifestations. HS severity is assessed using the Hurley Staging System (Table 1). It also remains unclear why hidradentitis may remain limited to Hurley Stage 1, evolve to the more confluent (Hurley Stage 2), or progress even further to the fully confluent (Hurley Stage 3).In addition, HS can be associated with other follicular based diseases such as pilonidal cysts (PCs) of the sacrum and buttocks, dissecting cellulitis (DC), and acne conglobata (AC), which usually involves the face, chest, When HS occurs with PCs, DC, and/or AC it is referred to as the follicular occlusion triad or tetrad [2]. HS can more rarely be associated with pyoderma gagrenosum (PG) or Crohn disease (CD), other inflammatory diseases of the skin that are not follicular. The reason for this is unclear [2]. What AC, DC, HS, CD, and PG share is that they occur in bacterially rich environments. HS probably occurs with acanthosis nigricans because many HS patients are obese [2]. This concurrence seems under reported. PMID:24746309

Évolution nycthémérale des composantes biochimiques du phytoplancton de la retenue du barrage Idriss premier (Fès, Maroc)  

NASA Astrophysics Data System (ADS)

The diel changes of the biochemical composition of the phytoplankton were studied in the Idriss first reservoir (located on the Inaouen river at thirty Km from the city of Fes, Morrocco) during September 1994. Several biomass and metabolic indicators (proteins, carbohydrates, lipids, chlorophyll a and primary production) were assessed every fourth hour over tow days (7, 8 and 9 September). Since the Protein/Carbohydrates ratio (P/C) is largely recognised as a good integrator of the metabolic functions of the cells, we examined its distribution pattern concomitantly with aforementioned parameters. The results demonstrated enhanced P/C ratios clearly indicating that nutrients were sufficiently available for growth. In addition, this index showed a diel significant variation with levels higher in the night than in the day. Moreover, these results suggest that phytoplankton species during the night used the day-synthesised carbohydrates to insure the cell metabolic functioning. The P/C presents relatively high values in proposition to the ones that have been recorded in temperate regions, and seems to be related to azotic inputs of the Inaouen river. Dans le but de parfaire nos connaissances sur le fonctionnement du sous écosystème phytoplancton, nous nous sommes intéressés à étudier son cycle nycthéméral et son métabolisme cellulaire dans la retenue du barrage Idriss premier. Cette dernière, construite sur l'Oued Inaouène, est située à une trentaine de Km de la ville de Fès. Au cours de ce cycle, les prélèvements ont été effectués selon une séquence temporelle de 4 heures pendant 48 heures, les 7, 8 et 9 septembre 1994. L'étude de l'évolution des composantes biochimiques des cellules phytoplanctoniques à savoir les protéines, les glucides et les lipides a permis de mettre en évidence des variations nycthémérales importantes. Ces variations sont d'autant plus importantes que les variations spatiales observées entre les profondeurs. De plus, le rapport protéines/glucides (P/G), reconnu comme un bon indicateur de l'état physiologique des algues, présente des valeurs plus élevées la nuit que le jour au niveau du fond du lac. Ce résultat suggère que le phytoplancton utilise les produits de réserve synthétisés le jour pour assurer le fonctionnement métabolique des cellules. De plus, les valeurs de ce rapport sont relativement élevées par rapport à celle enregistrées dans les régions tempérés et semblent être liées aux ressources azotées du milieu en particulier les apports de l'Oued Inaouène.

Defining parasite biodiversity at high latitudes of North America: new host and geographic records for Onchocerca cervipedis (Nematoda: Onchocercidae) in moose and caribou  

PubMed Central

Background Onchocerca cervipedis is a filarioid nematode of cervids reported from Central America to boreal regions of North America. It is found primarily in subcutaneous tissues of the legs, and is more commonly known as ‘legworm’. Blackflies are intermediate hosts and transmit larvae to ungulates when they blood-feed. In this article we report the first records of O. cervipedis from high latitudes of North America and its occurrence in previously unrecognized host subspecies including the Yukon-Alaska moose (Alces americanus gigas) and the Grant’s caribou (Rangifer tarandus granti). Methods We examined the subcutaneous connective tissues of the metacarpi and/or metatarsi of 34 moose and one caribou for parasitic lesions. Samples were collected from animals killed by subsistence hunters or animals found dead in the Northwest Territories (NT), Canada and Alaska (AK), USA from 2005 to 2012. Genomic DNA lysate was prepared from nematode fragments collected from two moose. The nd5 region of the mitochondrial DNA was amplified by PCR and sequenced. Results Subcutaneous nodules were found in 12 moose from the NT and AK, and one caribou from AK. Nematodes dissected from the lesions were identified as Onchocerca cervipedis based on morphology of female and male specimens. Histopathological findings in moose included cavitating lesions with multifocal granulomatous cellulitis containing intralesional microfilariae and adults, often necrotic and partially mineralized. Lesions in the caribou included periosteitis with chronic cellulitis, eosinophilic and lymphoplasmacytic infiltrate, and abundant granulation associated with intralesional adult nematodes and larvae. Sequences of the nd5 region (471bp), the first generated for this species, were deposited with Genbank (JN580791 and JN580792). Representative voucher specimens were deposited in the archives of the United States National Parasite Collection. Conclusions The geographic range of O. cervipedis is broader than previously thought, and extends into subarctic regions of western North America, at least to latitude 66°N. The host range is now recognized to include two additional subspecies: the Yukon-Alaska moose and Grant’s caribou. Accelerated climate change at high latitudes may affect vector dynamics, and consequently the abundance and distribution of O. cervipedis in moose and caribou. Disease outbreaks and mortality events associated with climatic perturbations have been reported for other filarioids, such as Setaria tundra in Fennoscandia, and may become an emerging issue for O. cervipedis in subarctic North America.

Local envenoming by the Western hognose snake (Heterodon nasicus): a case report and review of medically significant Heterodon bites.  

PubMed

A case of clinically significant local envenoming resulting from a bite inflicted by a Western hognose snake, Heterodon nasicus, is described. The patient was bitten while offering a juvenile mouse to a captive snake. The snake maintained a grip on the patient's arm (left anticubital fossa) for several minutes. The bite resulted in marked edema, ecchymoses, lymphadenopathy, cutaneous signs suggestive of mild cellulitis and blister formation. There were no systemic effects. Recovery was complete after approximately five months. Several documented Heterodon sp. bites with significant clinical effects are reviewed. This common xenodontine colubrid must be considered capable of inflicting medically significant bites. It is currently unclear whether the pathological changes associated with these bites are due to specific Duvernoy's secretion components, Type I hypersensitivity or a combination of these. The influence of the feeding response on the severity of clinical effects is considered as is the discrepancy between experimentally verified pharmacological activities of Duvernoy's secretions from Heterodon sp. and medical sequelae of documented bites. Although hognose snakes may uncommonly produce medically significant bites, they should not be considered dangerous or venomous. Captive specimens should be handled carefully, particularly when offered food. PMID:19393681

Insights into the Staphylococcus aureus-Host Interface: Global Changes in Host and Pathogen Gene Expression in a Rabbit Skin Infection Model  

PubMed Central

Staphylococcus aureus is an important cause of human skin and soft tissue infections (SSTIs) globally. Notably, 80% of all SSTIs are caused by S. aureus, of which ?63% are abscesses and/or cellulitis. Although progress has been made, our knowledge of the host and pathogen factors that contribute to the pathogenesis of SSTIs is incomplete. To provide a more comprehensive view of this process, we monitored changes in the S. aureus transcriptome and selected host proinflammatory molecules during abscess formation and resolution in a rabbit skin infection model. Within the first 24 h, S. aureus transcripts involved in DNA repair, metabolite transport, and metabolism were up-regulated, suggesting an increase in the machinery encoding molecules involved in replication and cell division. There was also increased expression of genes encoding virulence factors, namely secreted toxins and fibronectin and/or fibrinogen-binding proteins. Of the host genes tested, we found that transcripts encoding IL-8, IL1?, oncostatin M-like, CCR1, CXCR1 (IL8RA), CCL4 (MIP-1?) and CCL3 (MIP1?)-like proteins were among the most highly up-regulated transcripts during S. aureus abscess formation. Our findings provide additional insight into the pathogenesis of S. aureus SSTIs, including a temporal component of the host response. These results serve as a springboard for future studies directed to better understand how/why mild or moderate SSTIs progress to invasive disease. PMID:25719526

Septicaemia and meningitis caused by infection of New Zealand sea lion pups with a hypermucoviscous strain of Klebsiella pneumoniae.  

PubMed

This study describes a syndrome of neonatal septicemia and meningitis in New Zealand sea lions, caused by a strain of Klebsiella pneumoniae that is phenotypically similar to strains causing environmentally-acquired septicemia and neuro-invasive disease in humans. Between late 2006 and early 2010, 123 pups from the Enderby Island breeding colony died of K. pneumoniae infection, with lesions including fibrinous to fibrinosuppurative meningitis, subdural hemorrhage, septic arthritis, herniation and hemorrhage of the cerebellar vermis, lymphadenitis and cellulitis. This infection was responsible for 58% of observed pup mortality over this time period, with most deaths occurring in the latter part of the breeding season (mid February onwards). The results of this study suggest that the pattern of this disease has changed since it was first described in 2002, when most deaths occurred early in the season (early to mid-January), and that it is an important and consistent cause of pup mortality in this population. In addition, a similar disease syndrome and bacterial strain was diagnosed in a single pup in a fragile recolonizing New Zealand sea lion population on mainland New Zealand, and the potential effect on this population is unknown but could have a negative impact on recolonisation at this site.

Georges Marinesco (1863-1938): neurologist, neurohistologist and neuropathologist.  

PubMed

Gheorghe Marinescu (Georges Marinesco, in French) is a Romanian physician, founder of the School of Neurology in that country. He begins his medical studies in Bucharest, then has the opportunity to reach Paris and join the School of Neurology in La Salpêtrière Hospital, lead by Jean-Martin Charcot. This trip will forever imprint the mind of Marinescu, a great friend of France, a respectful student of Charcot and a friendly colleague of many Parisian neurologists. Marinescu's works are multiple and very important. He describes the succulent hand in syringomyelia and the palmar-jaw reflex. Marinescu is also one of the first to use the cinema for medical purposes. His work as an anatomo-clinician, a method developed by Charcot, is important. We denote the description of the locus niger affected by tuberculosis in a case of parkinsonism (this description paving Etienne Brissaud's way to highlight the anatomical origin of Parkinson's disease), the original clinical description of Marinesco-Sjögren syndrome, and that of medullomyoblastoma. Marinescu is also a famous neurocytologist as evidenced by his work, La Cellule Nerveuse, published in 1909. The first volume of the book is devoted to the aspects of the normal nervous tissue: the neurofibrillar network, the chromatophilic elements, and the paranucleolar corpuscles (now known as Marinescu's bodies). The second volume of the book is almost related to features revealed by experimental lesions: chromatolysis and neuronophagia. Furthermore, Marinescu describes with Oscar Blocq, small nodules than are now regarded as the first description of senile plaques. PMID:23303009

Tungiasis presenting as a soft tissue oral lesion  

PubMed Central

Background The sand flea Tunga penetrans usually infects the feet and affects primary school-age children and elderly persons in rural Uganda. Tungiasis occurs nationwide but disease outbreaks have been reported in the Busoga sub-Region of eastern Uganda, associated with poor sanitation and proximity between humans and domestic animals. Ectopic tungiasis, usually seen with extensive infection and at weight-bearing body surfaces often follows exposure in highly infested environments. For patients who present abroad treatment may be surgical excision or amputation. Case presentation An adult female Musoga by tribe, resident in a Kampala City suburb presented at Mulago National Referral and Teaching Hospital’s Oral Surgery and Jaw Injuries Unit with a discoloured swollen tongue, facial cellulitis and submandibular lymphadenopathy. A swelling palpable in the body of her tongue was excised and sent for histology. Tungiasis of the tongue was diagnosed after microscopic examination of formalin-fixed paraffin-embedded Haematoxylin and Eosin-stained tissue sections. Conclusion Lingual tungiasis is a rare diagnosis that was made on histological examination. Atypical presentation outside an endemic area predisposed the patient to partial glossectomy instead of the less invasive flea enucleation. Ectopic disease in a city-resident highlights the plight not only of visitors to infested areas but also of the communities and their domestic animals. PMID:25186303

Vacuum-assisted therapy accelerates wound healing in necrotizing soft tissue infections: our experience in two intravenous drug abuse patients.  

PubMed

Negative pressure wound therapy using vacuum-assisted closure (VAC) devices is currently a well established technique for managing complicated wounds. Such wounds occur after aggressive surgical debridement for necrotizing soft tissue infections (NSTI). In this report we present our experience in two intravenous drug abusers managed with VAC for NSTIs. The patients were 25 and 34 years old, HCV positive and presented with oedema of the upper femoral compartments and concomitant severe sepsis. Ultrasonography and computed tomography revealed severe cellulitis, fluid collection and necrosis of the affected fasciae and muscles. After emergent and subsequent aggressive surgical debridement during the first 48h, the VAC device was applied. Both patients had an uncomplicated postoperative course and a fast recovery from their multiorgan dysfunction. Suture closure of the wounds was achieved at the 25th and 38th postoperative days respectively and patients were discharged without any motor deficit. Negative pressure wound therapy is a modern therapeutic modality for treating complicated infected wounds. Moreover, it accelerates wound healing and primary closure, facilitating patient ambulation and recovery. A dedicated medical and nursing team is an important prerequisite for a successful outcome.

Staphylococcus lugdunensis Cultured from the Amniotic Fluid at Caesarean Section  

PubMed Central

Staphylococcus lugdunensis is a virulent coagulase-negative staphylococcus. It behaves like and can be mistaken in culture for Staphylococcus aureus. While originally thought to be a skin commensal rarely responsible for opportunistic infection, it was rapidly established as a significant human pathogen. It has been mainly associated with native and prosthetic valve endocarditis, osteomyelitis, and skin and soft tissue cellulitis, but has also been reported as a cause of fasciitis as well as peritonitis. Staphylococcus lugdunensis has been reported as a cause of endometritis but has not been previously isolated from amniotic fluid. Here, amniotic fluid samples were collected in the course of a larger study on amniotic fluid bacteriology, with prior ethical approval and informed patient consent. Amniotic fluid was obtained at Caesarean Section by direct needle aspiration from the intact amnion. Analysis with Staphylococcal API test kits led to identification of Staphylococcus lugdunensis in two cases. The clinical significance of the finding in these reported cases is undetermined. Staphylococcus lugdunensis has been shown to be a cause of serious and potentially fatal morbidities, but this is the first report of its culture from amniotic fluid. As caesarean delivery is accepted as the single most important factor associated with post-partum infectious complications in both mother and neonate, the identification of this pathogen is a new concern.

Going Out on a Limb: Do Not Delay Diagnosis of Necrotizing Fasciitis in Varicella Infection.  

PubMed

Necrotizing fasciitis (NF) is a rare complication of varicella zoster (chicken pox) infection. Its diagnosis can be delayed or missed, which increases mortality and morbidity, because it initially presents similarly to cellulitis. We present the case of a 5-year-old boy who presented with a swollen leg, the difficulties in the diagnosis of NF, and a review of the literature. Necrotizing fasciitis complicating varicella zoster in children is associated with 3.4% mortality, although this rises to 13.6% in streptococcal toxic shock syndrome. Seventy-one percent of cases are confirmed as being caused by group A ?-hemolytic Streptococcus. The association of NF with chicken pox is discussed along with the difficulties in diagnosis and treatment options. Necrotizing fasciitis is a surgical emergency and should be considered by all emergency department acute care practitioners in cases of varicella in which fever is enduring and swelling or pain is disproportionate. Because of the difficulty in diagnosis, senior opinion should be sought early. PMID:25356828

Community-acquired methicillin-resistant Staphylococcus aureus: a potential diagnosis for a 16-year-old athlete with knee pain  

PubMed Central

Objective This case report aims to raise awareness in chiropractic physicians of the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in adolescents who participate in sports activities and to alert the chiropractic physician of the necessity to consider potential diagnoses that are not within their typical clinical heuristic. Clinical Features A 16-year-old adolescent girl entered the clinic with a complaint of left knee pain that had an insidious onset during her involvement in sports activities. Later that same day, her knee became enlarged, red, and had pustular formations with a discharge. She was taken to an urgent care facility and subsequently diagnosed with MRSA. Her history included treatment of a left knee musculoskeletal condition 6 weeks prior to which she had responded favorably. Interventions and Outcomes She was treated medically with an aggressive course of antibiotic therapy and excision of the furuncle. The chiropractic physician played a role in patient education and notifying local school authorities of the case. Conclusion Doctors of chiropractic must prepare themselves for the unexpected and remain open to diagnostic possibilities outside of the normal scope of practice. Knee pain or cellulitis of any type may require additional diagnostic and patient care protocols to make the correct diagnosis. With the incidence of community-acquired MRSA increasing at an alarming rate, it is certainly a diagnosis doctors of chiropractic should be aware of when treating patients, especially those involved in sports activities.

Longitudinal evaluation of manual lymphatic drainage for the treatment of gynoid lipodystrophy*  

PubMed Central

BACKGROUND The gynoidlypodystrophy, known as cellulitis or cellulite, refers to a condition that gives the skin an undulating and uneven appearance, affecting 80-90% of women after puberty. OBJECTIVES to investigate the efficacy and safety of manual lymphatic drainage for cellulite management. METHODS this was an open, prospective, intervention study including 20 women aged from 20 to 40 years. Fourteen sessions of manual lymphatic drainage were performed once a week on lower limbs and buttocks. RESULTS Fifteen women completed the study. A significant improvement on quality of life was observed (p=0.018). A significant reduction (p=0.023), estimated at 0.3±0.8 cm, in hip circumference was found, but no difference was found in thighs circumference (p>0.05). A significant reduction elastic recuperation of skin on buttocks, which means skin elasticity worsening, was observed. All measures obtained by ultrasound images showed no changes (p>0.05). CONCLUSION manual lymphatic drainage was safe but not effective as an isolated approach for cellulite management. Further randomized, controlled or comparative studies about manual lymphatic drainage for cellulite control, as unique or combined therapeutic modality, are necessary. PMID:25184909

A Case Report of Herpetic Whitlow with Positive Kanavel's Cardinal Signs: A Diagnostic and Treatment Difficulty.  

PubMed

Herpetic whitlow is an acute viral infection of the hand caused by either herpes simplex virus (HSV) 1 or 2. Its characteristic findings are significant pain and erythema with overlying nonpurulent vesicles. The differential diagnosis includes flexor tenosynovitis. We present a case of recurrent infection of the middle finger in an immunocompetent 19-year-old girl. Multiple painful pustules with tracking cellulitis were partially treated by oral antibiotics. A recurrence with positive Kanavel's signs suggested flexor tenosynovitis at seven months. Her symptoms improved transiently following emergent surgical open flexor sheath exploration and washout however, she required two further washouts; at eleven and thirteen months to improve symptoms. Viral cultures were obtained from the third washout as HSV infection was disclosed from further history taking. These were positive for HSV2. Treatment with acyclovir at thirteen months after presentation led to a complete resolution of her symptoms with no further recurrences to date. This rare case highlights the similarity in presentation between flexor sheath infection and herpetic whitlow which can lead to diagnostic confusion and mismanagement. We emphasise the importance of careful past medical history taking as well as considering herpetic whitlow as a differential diagnosis despite the presence of strongly positive Kanavel's signs.

Type I Interferon Production Induced by Streptococcus pyogenes-Derived Nucleic Acids Is Required for Host Protection  

PubMed Central

Streptococcus pyogenes is a Gram-positive human pathogen that is recognized by yet unknown pattern recognition receptors (PRRs). Engagement of these receptor molecules during infection with S. pyogenes, a largely extracellular bacterium with limited capacity for intracellular survival, causes innate immune cells to produce inflammatory mediators such as TNF, but also type I interferon (IFN). Here we show that signaling elicited by type I IFNs is required for successful defense of mice against lethal subcutaneous cellulitis caused by S. pyogenes. Type I IFN signaling was accompanied with reduced neutrophil recruitment to the site of infection. Mechanistic analysis revealed that macrophages and conventional dendritic cells (cDCs) employ different signaling pathways leading to IFN-beta production. Macrophages required IRF3, STING, TBK1 and partially MyD88, whereas in cDCs the IFN-beta production was fully dependent on IRF5 and MyD88. Furthermore, IFN-beta production by macrophages was dependent on the endosomal delivery of streptococcal DNA, while in cDCs streptococcal RNA was identified as the IFN-beta inducer. Despite a role of MyD88 in both cell types, the known IFN-inducing TLRs were individually not required for generation of the IFN-beta response. These results demonstrate that the innate immune system employs several strategies to efficiently recognize S. pyogenes, a pathogenic bacterium that succeeded in avoiding recognition by the standard arsenal of TLRs.

A Simple Approach to Specimen Retrieval via Posterior Colpotomy Incision  

PubMed Central

Introduction: Posterior colpotomy incision for specimen retrieval is infrequently used in gynecologic laparoscopic surgery unless a concomitant hysterectomy is performed. We aim to describe a simple and unique technique for creating the colpotomy incision and to describe intraoperative and postoperative outcomes. Methods: Fifty patients underwent adnexal specimen retrieval through a posterior colpotomy incision. After devascularization and detachment of the adnexal specimen, the posterior cul-de-sac was visualized. The colpotomy incision was created by introducing a 12- or 15-mm laparoscopic trocar through the vagina into the posterior vaginal fornix under direct visualization. Specimens were placed into laparoscopic bags and removed through the vagina. The colpotomy incision was closed vaginally. Charts were reviewed for intraoperative and postoperative outcomes. Results: Twenty-nine women underwent adnexal surgery for an adnexal mass, 14 women underwent surgery for pelvic pain, and 7 women underwent adnexal surgery for primary prevention of malignancy. The specimens removed ranged in size from 2 to 16 cm (mean 5.7). The mean time patients were under anesthesia was 103 minutes (SD 57.3). There were no operative complications related to the colpotomy incision and no cases of postoperative vaginal cellulitis or pelvic infection were reported. Only 1 woman with a prior vaginal delivery reported dyspareunia postoperatively. Conclusion: This simple technique for posterior colpotomy incision can easily be added to the gynecologic surgeon's armamentarium and can be safely used for most women.

Cicatricial alopecia as a manifestation of different dermatoses.  

PubMed

There are numerous dermatoses which may cause cicatricial alopecia when localized on the scalp, such as chronic discoid lupus erythematosus (DLE), lichen planus, graft-versus-host disease, dermatomyositis, scleroderma, cicatricial pemphigoid, porphyria cutanea tarda, follicular mucinosis, perifolliculitis capitis abscedens, lichen sclerosus et atrophicus, necrobiosis lipoidica, sarcoidosis, etc. Histologically, cicatricial alopecia is characterized by dermal scarring, along with absent or reduced hair follicles and reduced number of erector pili muscles. According to working classification of cicatricial alopecia by the North American Hair Society, primary cicatricial alopecia may be divided into the following categories: lymphocytic group (e.g., DLE, lichen planopilaris, classic pseudopelade (Brocq), central centrifugal cicatricial alopecia); neutrophilic group (e.g., folliculitis decalvans, dissecting cellulitis); and mixed group (e.g., folliculitis keloidalis). Over a 5-year period, 36 patients with cicatricial alopecia were hospitalized at our Department: DLE (n = 27), pseudopelade Brocq (n = 3), mucinosis follicularis (n = 2), and lichen planopilaris, folliculitis decalvans, folliculitis abscedens and folliculitis keloidalis (one patient each). Clinical evaluation was compared with histopathologic analysis of follicular architecture, as well as with the type, localization and extent of inflammatory infiltrate. Scalp biopsy was considered mandatory in all cases. Our experience indicates the need of more complex research to extend the knowledge about the etiopathogenesis and treatment options for cicatricial alopecia. We hope that this type of alopecia may attract more attention and research in the future. PMID:17311739

Approche morphologique de la fragmentation de l'ADN radio-induite par immunomarquage anti-poly (ADP-ribose) polymérase (PARP) : étude de cultures d'oligodendrogliomes  

NASA Astrophysics Data System (ADS)

Poly (ADP-ribose) polymerase (PARP) is a nuclear enzyme encompassing two zinc finger motifs which specifically binds to radiation induced DNA strand breaks. We develop a new immuno-labelling of poly ADP-ribose which coupled together with the immunodetection of cells in cycle with MIB1, permits to detect and quantify the DNA fragmentation induced by radiations (Cesium137). This method, applied to organotypical cultures of human oligodendroglioma, submitted to radiation, a dose dependant nuclear signal. This one increased significantly in the presence of a radiosensitizer like iododeoxyuridine (IUDR 5 g/ml). This poly ADP-ribose immunodetection can be useful, to detect furtherly the individual radiosensitivity of human glioma. Les protéases “ICE-like" ou caspases, sont les homologues humaines du produit du gène ced-3 du ver Caenorhabditis elegans et sont activées lors des étapes précoces de l'apoptose. L'objectif de ce travail vise à déterminer dans quelle mesure l'inhibition de l'une d'entre elles, la caspase-3 est susceptible de modifier la sensibilité des cellules vis-à-vis de l'apoptose radioinduite. Des lymphocytes spléniques murins irradiés en présence de Ac-DVED-CHO un inhibiteur spécifique de la caspase-3 présentent un taux de particules hypodiploïdes radioinduites bien inférieur à celui des contrôles et une diminution drastique de la fragmentation internucléosomale de l'ADN. Toutefois, ni l'externalisation des phospholipides anioniques, autre marqueur spécifique de l'apoptose, ni la viabilité ne sont affectées.

Shewanella and Photobacterium spp. in oysters and seawater from the Delaware Bay.  

PubMed

Shewanella algae, S. putrefaciens, and Photobacterium damselae subsp. damselae are indigenous marine bacteria and human pathogens causing cellulitis, necrotizing fasciitis, abscesses, septicemia, and death. Infections are rare and are most often associated with the immunocompromised host. A study was performed on the microbiological flora of oysters and seawater from commercial oyster harvesting sites in the Delaware Bay, New Jersey. From 276 water and shellfish samples tested, 1,421 bacterial isolates were picked for biochemical identification and 170 (12.0%) of the isolates were presumptively identified as S. putrefaciens, 26 (1.8%) were presumptively identified as P. damselae subsp. damselae, and 665 (46.8%) could not be identified using the API 20E identification database. Sequencing of the 16S rRNA genes of 22 S. putrefaciens-like isolates identified them as S. abalonesis, S. algae, S. baltica, S. hafniensis, S. marisflavi, S. putrefaciens, Listonella anguillarum, and P. damselae. Beta-hemolysis was produced by some S. algae and P. damselae isolates, while isolates of S. baltica and L. anguillarum, species perceived as nonpathogenic, also exhibited beta-hemolysis and growth at 37 degrees C. To our knowledge, this is the first time these beta-hemolytic strains were reported from shellfish or seawater from the Delaware Bay. Pathogenic Shewanella and Photobacterium species could pose a health threat through the ingestion of contaminated seafood, by cuts or abrasions acquired in the marine environment, or by swimming and other recreational activities.

A Case of Helicobacter cinaedi Bacteremia in an Asplenic Patient  

PubMed Central

Helicobacter cinaedi is an enterohepatic species. It can cause bacteremia, gastroenteritis, and cellulitis, particularly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, malignancy, or alcoholism. There are no previous reports of H. cinaedi infection in Korea. A 71-yr-old man was admitted to the emergency room because of dyspnea on November 9, 2011. He had undergone splenectomy 3 yr ago because of immune hemolytic anemia. Chest plain radiography revealed bilateral pleural effusion. He developed fever on hospital day (HD) 21. Three sets of blood cultures were taken, and gram-negative spiral bacilli were detected in all aerobic vials. The isolate grew in tiny colonies on chocolate agar after 3-day incubation under microaerophilic conditions. This organism tested positive for catalase and oxidase, and negative for urease. The 16S rRNA gene sequence of this isolate exhibited 99.8% homology with the published sequence of H. cinaedi CCUG 18818T (GenBank accession no. ABQT01000054) and 98.5% homology with the sequence of Helicobacter bilis Hb1T (GenBank accession no. U18766). The patient was empirically treated with piperacillin/tazobactam and levofloxacin, and discharged with improvement on HD 31. To our knowledge, this is the first report of H. cinaedi bacteremia in an asplenic patient. Asplenia appears to be a risk factor for H. cinaedi bacteremia. PMID:23130344

The first leg video endoscopic groin lymphadenectomy in vulvar cancer: A case report  

PubMed Central

INTRODUCTION The current management of vulvar cancer depends on the extension of disease, and includes primary tumor resection with safety margin as well as inguinofemoral lymph node staging. We report the case of the first leg videoendoscopic inguinal lymphadenectomy performed in a woman with a squamous cell vulvar carcinoma. PRESENTATION OF CASE A 74 years old female referred to our institution complaining of vulvar mass associated with bleeding and swelling from external genitals, vaginal burning sensation and dysuria for 5 months. A vulvar–vaginal examination under narcosis reported a right major labium lesion of 5 cm with an irregular and ulcerated surface, easily bleeding on palpation, involving anteriorly the clitoral region and with a histological finding of a poorly differentiated squamous cell invasive carcinoma of the vulva ulcerating the surface epithelium. We performed, after adequate informed consent, a radical vulvectomy with a standard right inguinofemoral lymphadenectomy and a contralateral simultaneous video endoscopic inguinal lymphadenectomy-Leg procedure. DISCUSSION Our minimally invasive VEIL-Leg approach, performed for the first time in literature in a woman with vulvar cancer, could reduce the presence of high risk factors represented by surgical incision and by procedure-related complications, including wound infection and breakdown, hematoma, cellulitis and hernia formation. CONCLUSION A multicenter prospective randomized study will be helpful to clarify how this procedure could replace the standard laparotomic approach to inguinal lymphadenectomy in the vulvar cancer treatment and staging.

Multisystemic toxoplasmosis associated with a type II-like Toxoplasma gondii strain in a New Zealand fur seal (Arctocephalus forsteri) from New South Wales, Australia.  

PubMed

We report the first confirmed case of toxoplasmosis in an Australian pinniped. Presence of Toxoplasma gondii DNA was detected in the brain of a free-ranging subadult New Zealand fur seal (Arctocephalus forsteri) with nonsuppurative meningoencephalitis, hypophysitis, posterior uveitis, retrobulbar cellulitis, and myocarditis associated with protozoan cysts and tachyzoites. The emaciated seal stranded moribund on a beach in northern Sydney in New South Wales. Histopathology coupled with specific immunohistochemistry and PCR assays confirmed the presence of T. gondii. The T. gondii sample (NZfs8825) identified in this study has an identical genotype as the type II (ToxoDB PCR-RFLP genotype #1) based on the direct sequencing and virtual RFLP of multilocus DNA markers including SAG1, 5'- and 3'-SAG2, alt.SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, and Apico. Direct sequencing of T. gondii B1 DNA marker from the T. gondii sample (NZfs8825) identified a type II-like strain, based on presence of non-archetypal B1 gene polymorphisms previously reported as unique to Australia. This study suggests that T. gondii oocysts originating from mainland Australia, which has a large population of feral cats, may act as a disease threat to native marine fauna. Therefore, emerging toxoplasmosis in the Arctic has a relevant parallel in the Southern Ocean within Australian waters with yet unknown relevance to Antarctica. PMID:25123611

The role of primary care prescribers in the diagnosis and management of community-associated methicillin-resistant Staphylococcus aureus skin and soft tissue infections.  

PubMed

Nosocomial infections caused by methicillin-resistant Staphylococcus aureus were first reported in the United States in the early 1960s. Beginning in the 1990s, healthy individuals from the community with no risk factors for resistant bacteria began presenting with methicillin-resistant Staphylococcus aureus infections, acquiring the name "community-associated methicillin-resistant Staphylococcus aureus" (CA-MRSA). CA-MRSA has a tendency to affect the skin and skin structures, generally in the form of abscesses and furuncles, carbuncles, and cellulitis. Cases of invasive infections including bacteremia, endocarditis, and necrotizing pneumonia have also been reported. A patient complaint of a "spider bite" is frequently associated with CA-MRSA. CA-MRSA and the traditional health care-associated methicillin-resistant Staphylococcus aureus are distinguished by their genetic composition, virulence factors, and susceptibility patterns to non-beta-lactam antibiotics. Appropriate management of CA-MRSA skin and skin structure infections includes incision and drainage of infected tissue and appropriate antimicrobial therapy. It has been suggested that when prevalence of CA-MRSA within a community eclipses 10%-15%, empiric use of non-beta-lactam antibiotics with in vitro activity against CA-MRSA be initiated when treating skin and skin structure infections. CA-MRSA retains susceptibility to a range of older antibiotics available in oral formulations such as minocycline, doxycycline, sulfamethoxazole-trimethoprim, moxifloxacin, levofloxacin, and clindamycin. Local susceptibility patterns and individual patient factors should guide the selection of antibiotics. PMID:19617720

The global burden of skin disease in 2010: an analysis of the prevalence and impact of skin conditions.  

PubMed

The Global Burden of Disease (GBD) Study 2010 estimated the GBD attributable to 15 categories of skin disease from 1990 to 2010 for 187 countries. For each of the following diseases, we performed systematic literature reviews and analyzed resulting data: eczema, psoriasis, acne vulgaris, pruritus, alopecia areata, decubitus ulcer, urticaria, scabies, fungal skin diseases, impetigo, abscess, and other bacterial skin diseases, cellulitis, viral warts, molluscum contagiosum, and non-melanoma skin cancer. We used disability estimates to determine nonfatal burden. Three skin conditions, fungal skin diseases, other skin and subcutaneous diseases, and acne were in the top 10 most prevalent diseases worldwide in 2010, and eight fell into the top 50; these additional five skin problems were pruritus, eczema, impetigo, scabies, and molluscum contagiosum. Collectively, skin conditions ranged from the 2nd to 11th leading cause of years lived with disability at the country level. At the global level, skin conditions were the fourth leading cause of nonfatal disease burden. Using more data than has been used previously, the burden due to these diseases is enormous in both high- and low-income countries. These results argue strongly to include skin disease prevention and treatment in future global health strategies as a matter of urgency. PMID:24166134

Bacterial skin infections, active component, U.S. Armed Forces, 2000-2012.  

PubMed

From 2000 through 2012, health care records of the Military Health System documented 998,671 incident cases of bacterial skin infections among active component members of the U.S. Armed Forces. Most cases (97.3%) were identified from records of outpatient medical encounters rather than hospitalizations. Cellulitis accounted for half (50.9%) of all cases of bacterial skin infection but 96 percent of associated hospital bed days. Of all cases, 42.3 percent were "other" skin infections (i.e., folliculitis, impetigo, pyoderma, pyogenic granuloma, other and unspecified infections). The remainder were attributable to carbuncles/furuncles (6.6%) and erysipelas (0.1%). Rates of infection were higher among female service members except for "other" skin infections. In general, the highest rates were associated with youth, recruit trainee status, and junior enlisted rank; however, rates of erysipelas were highest among those 50 years and older. Annual incidence rates of all bacterial skin infections have increased greatly since 2000. During the entire period, such infections required more than 1.4 million health care encounters and 94,000 hospital bed-days (equivalent to 257 years of lost duty time). The prevention, early diagnosis, and treatment of bacterial skin infections, particularly in high risk settings, deserve continued emphasis. PMID:24428536

Foot ischemia after a free fibula flap harvest: immediate salvage with an interpositional sapheneous vein graft.  

PubMed

The most dreaded major donor-site complication of free fibula flap is a foot ischemia, which is fortunately rare. Various authors have discussed the efficacy of the use of preoperative imaging methods including color Doppler, magnetic resonance angiography, and conventional angiography. A 25-year-old man presented with a 10-cm mandibular defect after a facial gunshot injury. Lower extremity color Doppler revealed triphasic peroneal, tibialis anterior, and posterior artery flows. A fibula osteocutaneous flap was harvested, and the mandible was reconstructed. However, the suture sites at the donor site began to demonstrate signs of necrosis, abscess formation, and widespread cellulitis beginning from postoperative day 9. Angiogram of the lower extremity on the 13th day demonstrated no flow in the right posterior tibial artery distal to the popliteal artery, whereas the anterior tibial artery had weak flow with collateral filling distally. An emergency bypass with a saphenous vein graft between the popliteal artery and the distal posterior tibial artery was performed. Repeated debridements, local wound care, and vacuum-assisted closure were applied. A skin graft was placed eventually. The extremity healed without severe functional disability. In conclusion, although the arterial anatomy is completely normal in preoperative evaluation, vascular complications may still ocur at the donor fibula free flap site. In addition, emergency cardiovascular bypass surgery, as we experienced, may be necessary for limb perfusion. PMID:25119400

Compact or fractal patterns in diffusion limited growth  

NASA Astrophysics Data System (ADS)

Fractal viscous fingering patterns are observed in an infinite Hele-Shaw cell at long times when the capillary forces become negligible. On the contrary, growth of monocrystals from a punctual seed shows dendrites growing independently in 4 or 6 directions, according to the crystal symmetry. A close comparison of numerical and experimental data explains first the origin of the tip-splitting instability in radial growth and shows that it can be inhibited by the anisotropy of surface tension. Des structures fractales ont été observées en digitations visqueuses en cellule de Hele-Shaw et aux temps longs lorsque les forces capillaires deviennent négligeables. Par opposition, la croissance de monocristaux à partir d'un germe ponctuel fait apparaître des dendrites croissant dans 4 ou 6 directions selon la symétrie cristalline. Une comparaison entre des résultats numériques et des données expérimentales explique l'origine de l'instabilité de dédoublement des pointes en croissance radiale et montre qu'elle peut être supprimée par l'anisotropie cristalline.

Successful medical treatment for globe penetration following tooth extraction in a dog.  

PubMed

A five-year-old entire male Tibetan Terrier was referred for left-sided periorbital swelling and blepharospasm 4 days following ipsilateral maxillary tooth extraction. Examination of the left eye revealed mild exophthalmos, pain on retropulsion, and absent menace response and pupillary light reflexes. Examination of the posterior segment was not possible owing to the anterior segment pathology. Differential diagnoses considered were iatrogenic globe penetration and peribulbar abscess/cellulitis. Ocular ultrasound was consistent with a penetrating wound to the globe. Treatment with systemic prednisolone and marbofloxacin, and topical atropine sulfate 1%, prednisolone acetate, and brinzolamide was started. Marked clinical improvement allowed visual confirmation of the perforation. Oral prednisolone was tapered over the following 10 weeks. At final re-examination (10 months), the patient was visual, and fundic examination revealed an additional chorioretinal scar, most likely an exit wound that was obscured by vitreal debris on initial examinations. Neither scar was associated with retinal detachment. To the authors' knowledge, this is the first reported case of successful medical management of iatrogenic globe penetration following exodontic procedures. PMID:23869648

[Case of prostate cancer associated with bisphosphonate-related osteonecrosis of the jaw followed by retropharyngeal abscess].  

PubMed

A 67-year-old man with castration-resistant prostate cancer associated with multiple bone metastases had been treated with zoledronic acid and docetaxel. Although there was no evidence of damage around the right lower jaw bone, the patient complained of pain in May 2011, which worsened during the next 2 weeks and was followed by difficulty with breathing. Computed tomographic (CT) findings of the cervical area showed swelling of the cervical tissue with air and tightening of the trachea, suggesting cellulitis caused by gas gangrene. He was intubated and treated with antibiotics. On the 12th hospital day, CT scan revealed a pharyngeal abscess and we performed a drainage operation. On the 20th hospital day, bone of the intraoral lower jaw was exposed, revealing that the infection was caused by osteonecrosis. Additional CT findings showed the abscess extending to the mediastinum and multiple liver metastases. Although antibiotic therapy was continued, the patient died of liver failure on the 61st day.

Noninvasive evaluation of the swollen extremity: Experiences with 190 lymphoscintigraphic examinations  

SciTech Connect

Lymphoscintigraphy (LS), performed with technetium 99m-labeled antimony trisulfide colloid, was used as a noninvasive diagnostic examination to evaluate the lymphatic circulation in 190 extremities of 115 patients. Forty-six patients had primary lymphedema, 48 had secondary lymphedema, and 21 patients had other causes of limb swelling. To determine the value of LS in surgical decision making, preoperative and postoperative LS of 16 patients who underwent surgical repair of the lymphatic abnormality were studied separately. Semiquantitative evaluation of the lymphatic drainage and visual interpretation of the image patterns were reliable to differentiate lymphedema from edemas of other origin (sensitivity: 92%, specificity: 100%). Although certain image patterns were characteristic of either primary or secondary lymphedema, LS could not consistently differentiate between the two types. Episodes of cellulitis in lymphedema clearly delayed lymph transport. LS was helpful in patient selection and follow-up after lymphatic surgery, but it did not prove patency of lymphovenous anastomoses. It was diagnostic in the evaluation of lymphangiectasia and was used to document successful surgical treatment of reflux of chyle. LS is safe and reliable and has no side effects. It should replace contrast lymphangiography in the routine evaluation of the swollen extremity.

Complications and outcomes of brown recluse spider bites in children.  

PubMed

Brown recluse spider bites may cause severe local and systemic morbidity, but data regarding morbidity in children are limited. This study reviewed inpatient medical records (n = 26; 10 years) with a discharge diagnosis of "spider bite" from a tertiary pediatric hospital. The majority (85%) of children had an inflammatory response accompanying necrosis, usually with signs of secondary cellulitis (77%). Hemolytic anemia (50%), rhabdomyolysis (27%), and acute renal failure (12%) were the most prevalent systemic effects. Hemolytic anemia was bimodal in distribution relative to the time-of-onset of the bite (early, 2.2 ± 0.4; late, 6.9 ± 1.5 days postbite, respectively; P = .004). Although no fatalities occurred in the population, 65% of children had major morbidity, including wound complications requiring surgical care and acute orbital compartment syndrome. The findings emphasize the importance of anticipatory patient/family education for outpatients and careful monitoring for systemic morbidity in inpatients. Timely and appropriate supportive care should yield favorable outcomes in most cases. PMID:21307081

Milroy disease and the VEGFR-3 mutation phenotype  

PubMed Central

Primary congenital lymphoedema (Milroy disease) is a rare autosomal dominant condition for which a major causative gene defect has recently been determined. Mutations in the vascular endothelial growth factor receptor 3 (VEGFR-3) gene have now been described in 13 families world-wide. This is a review of the condition based on the clinical findings in 71 subjects from 10 families. All 71 individuals have a mutation in VEGFR-3. Ninety per cent of the 71 individuals carrying a VEGFR-3 mutation showed signs of oedema, which was confined in all cases to the lower limbs. In all but two cases onset of swelling was from birth. Other symptoms and signs included cellulitis (20%), large calibre leg veins (23%), papillomatosis (10%), and upslanting toenails (10%). In males, hydrocoele was the next most common finding after oedema (37%). Thorough clinical examination of these patients indicates that there are few clinical signs in addition to lower limb oedema. Rigorous phenotyping of patients produces a high yield of VEGFR-3 mutations. PMID:15689446

Lymphedema and subclinical lymphostasis (microlymphedema) facilitate cutaneous infection, inflammatory dermatoses, and neoplasia: A locus minoris resistentiae.  

PubMed

Whether primary or secondary, lymphedema is caused by failure to drain protein-rich interstitial fluid. Typically affecting a whole limb, it has become apparent that lymphedema can also affect localized regions of the skin, or it can be clinically silent but histologically evident, denoted by dilated lymphangiectases (latent lymphedema). Chronic lymph stasis has numerous consequences, including lipogenesis, fibrosis, inflammation, lymphangiogenesis, and immunosuppression. For example, lymphedema's disruption of immune cell trafficking leads to localized immune suppression, predisposing the area affected to chronic inflammation, infection (cellulitis and verrucosis), and malignancy (angiosarcoma and nonmelanoma skin cancer). The pathogenesis of lymphedema is reviewed and exemplified by describing how a combination of lymph stasis-promoting factors such as trauma, obesity, infection, and inflammatory disorders produces localized elephantiasis; furthermore, the finding of lymphangiectases is found to be common in numerous dermatologic disorders and argued to play a role in their pathogenesis. Lastly, it is discussed how antigen burden, which is controlled by lymphatic clearance, affects the immune response, resulting in immune tolerance, immunopathology, or normal adaptive immunity.
