    There is no relation between what French women call "cellulitis" and the venous problems of genetic origin. It may be that cellulitis is the name given to those extra kilos, to mild obesity, to fatty deposits on the thighs and buttocks (sub-trochanteric and crural steatomeries: "jodhpurs"); the point is that cellulitis is apparent, either immediately or on pinching the skin, as an orange-peel pitting. This problem exteriorises the lobular structure of the surface fat. This derives from excessively large lobules, cutaneous relaxation, or excessive pressure on the walls separating the lobules into compartments. Slimming reduces the large areas of deposit at the base of the buttocks. Musculation of the thighs can improve their appearance. More people think they have cellulitis than are really afflicted with it; this is just one of the many deceptions associated with it. PMID:4095152

    Tinea capitis is a common disease of childhood that typically follows one of several clinical patterns. Our patient and several previously reported cases demonstrate the existence of a dissecting cellulitis-like presentation of tinea capitis. This variant should be recognized to prevent misdiagnosis of dissecting cellulitis and allow proper treatment to prevent scarring alopecia. PMID:24134312

    Pediatric preseptal and orbital cellulitis are infectious disorders that result in periorbital inflammation. Preseptal cellulitis is often associated with breaches in the skin barrier whereas orbital cellulitis is commonly associated with paranasal sinusitis. Orbital cellulitis may be associated with subperiosteal abscess. It is important to distinguish between preseptal from orbital cellulitis. Clinical examination and diagnostic imaging are useful in determining appropriate management. Patients are usually treated with broad spectrum antibiotics and surgery when indicated. PMID:20616919

    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.

    Cellulitis is an acute bacterial non-necrotizing dermal-hypodermal infection predominantly affecting the lower limbs. It is characterised by a circumscribed erythema with a raised border and fever. The predisposing factors are skin wounds, edema from any cause and systemic factors (diabetes, immunosuppression). The diagnosis is clinical and the most common complication is recurrence. Other complications include local abscess, fasciitis and bacteremia. The germ is rarely identified. The majority of infections (85%) is due to group A beta-hemolytic streptococcus. The treatment of cellulitis consists of an association of an antibiotic with rest of the concerned area.

    Erysipelas and infectious cellulitis are skin infections that develop following the entry of bacteria through gaps in the skin. The most common complication is recurrence. Control of predisposing factors remains essential to prevent it. Prophylactic antibiotics are sometimes prescribed, but this approach is based on small studies and expert opinion. This article reflects the current state of knowledge and the standard of care.

    Several common conditions can mimic cellulitis, creating a potential for misdiagnosis and incorrect management. The most common disorders mistaken for lower limb cellulitis include venous eczema, lipodermatosclerosis, irritant dermatitis, and lymphedema. The dermatologist is often consulted when a patient has failed to respond to therapy, and a thorough knowledge of the differential diagnosis is essential. This article focuses on entities that can mimic cellulitis, with an emphasis of elements of the history and physical examination that can help to distinguish between lower limb cellulitis and its simulators.

    An 89-year-old man presented with an inflammatory erythematous plaque on the left thigh that closely mimicked cellulitis. Empiric therapies with ordinary antibiotics were not effective. A skin biopsy showed epithelioid cell granulomas throughout the dermis and subcutis. Ziehl-Neelsen stain revealed numerous acid-fast bacilli. Additionally, Mycobacterium tuberculosis was isolated from a skin biopsy specimen as well as gastric fluid and sputum cultures. He was diagnosed with tuberculous cellulitis with pulmonary tuberculosis. Cellulitis is a common disease seen by dermatologists; however, sometimes other diseases may masquerade as this banal illness. Among them, cutaneous tuberculosis should be excluded because of its clinical significance. Most cases of cutaneous tuberculosis are symptom free, but tuberculous cellulitis is sometimes painful. Therefore, cutaneous tuberculosis should always be considered in the differential diagnosis of a cellulitislike rash if the lesions do not respond to ordinary antibiotic therapy, especially in countries with a high incidence of tuberculosis.

    A case of cellulitis was observed in Japanese quail (Coturnix coturnix japonica) reared for commercial meat production. This condition in Japanese quail has not been reported in the literature. This incident was the first, and to date only, occurrence of cellulitis in this processing plant. The cellulitis lesions were localized to the subcutis overlying the breast and inner thigh. Carcasses of processed birds and live birds from the affected farm were presented to the Poultry Diagnostic and Research Center, University of Georgia. Escherichia coli was cultured from the lesion. The affected live birds displayed lameness and had osteomyelitis. Pasteurella multocida serotype 3,4 was cultured from the liver and bone marrow of affected birds. Approximately 4.61% of the processed carcasses from the flock were condemned because of cellulitis. This represented a 10fold increase from the typical condemnation rate. Further investigation revealed birds were placed in higher than normal density; therefore, we theorize that the concurrent pasteurellosis and increased placement density resulted in the cellulitis condition.

    Infectious intracranial aneurysm and cavernous sinus thrombosis are rare complications of orbital cellulitis. We report the case of a 46-year-old male presenting with sinusitis and orbital cellulitis complicated by the development of an orbital mass. Following orbitotomy with debulking, the patient underwent bony orbital decompression for increasing proptosis postoperatively. While his exam stabilized, the patient developed complete ptosis and extraocular motor palsy in the contralateral eye after undergoing bilateral sinus debridement. Imaging was notable for the presence of a pseudoaneurysm of the internal carotid artery, which was treated with a stent. This report demonstrates rare complications of orbital cellulitis. These patients should be monitored carefully with noninvasive imaging studies, such as cerebral angiography, for early detection of vascular abnormalities that can progress rapidly. PMID:25955309

    A 55-year-old woman presented with a 3-year history of recurrent episodes of pruritic cellulitis-like erythematous plaques, mostly located on the limbs. Simultaneously, fever, malaise and peripheral eosinophilia were noted. The clinical diagnosis of eosinophilic cellulitis (also known as Well's syndrome) was supported by the histopathological finding of typical "flame figures". Treatment with dapsone was initiated at a dose of 50 mg per day. After one year of follow-up the patient was relapse-free. Eosinophilic cellulitis is an uncommon, recurrent inflammatory skin disease. The management is often a challenge, due to the frequent need for long-term therapy. Dapsone is an effective and safe treatment option. PMID:27617724

    Bullous leukemia cutis is an uncommon clinical manifestation of cutaneous infiltration by leukemic cells, from B-cell chronic lymphocytic leukemia. We present the case of a 67-year-old, female, chronic lymphocytic leukemia patient. She was taking chlorambucil and developed facial edema with erythema and warmth, misjudged as facial cellulitis. Two days later, she developed bullous lesions in the arms, legs, neck and face. The histopathology of facial and bullous lesions confirmed leukemia cutis. All lesions disappeared following the administration of rituximab combined with cycles of fludarabine and cyclophosphamide. Although soft tissue infections are common complications in patients undergoing chemotherapy, leukemia cutis can also resemble cellulitis. PMID:27192532

    2015-01-01

    Wells' syndrome (WS), or eosinophilic cellulitis, is an uncommon inflammatory dermatosis of unknown etiology that typically presents with pruritic cellulitis-like plaques on the extremities. Therefore, WS is often misdiagnosed as bacterial cellulitis due to its similarity in presentation. Here, we report two cases of WS that masqueraded as bacterial facial cellulitis. Under treatment with oral prednisone and/or a combination therapy with levocetirizine and hydroxyzine, both patients showed a dramatic improvement of the skin lesions. These cases highlight the need for clinicians to consider WS in the differential diagnosis when evaluating a patient with facial cellulitis that does not respond to an initial antimicrobial regimen. In addition, our cases suggest that combination therapy with levocetirizine and hydroxyzine may be successfully used as corticosteroid-sparing treatment or to prevent relapse after the discontinuation of corticosteroid treatment.

    Sweet's syndrome is a neutrophilic dermatosis with worldwide distribution that has been associated with inflammatory autoimmune diseases, infections, malignancies, drugs, and pregnancy. The disease is idiopathic in up to 50% of patients. A 64-year-old woman, diagnosed with right limb cellulitis (4 days of evolution), was seen at our department, due to persistent cellulitis and progressive appearance of painful nodules and plaques in both shins and the right forearm (2 days of evolution). Taken together, clinical, laboratory and pathological data suggested the diagnosis of Sweet's syndrome, probably secondary to cellulitis of the right inferior limb. We suggest that cellulitis may be associated with Sweet's syndrome, a rare association in the literature. PMID:26982787

    In this article we have reviewed the clinical and bacteriologic aspects of anaerobic orbital cellulitis and have presented six patients to illustrate these points. Physicians who treat patients with orbital cellulitis should have a high index of suspicion for possible instances involving anaerobes, so that appropriate management can be started early. To investigate this problem further, we created an animal model of anaerobic orbital cellulitis. This model may be useful in future studies of the pathogenesis and treatment of this serious and often devastating disease.

    Background Prior studies repeatedly showed that cultures of skin lesions diagnosed as "cellulitis" are usually negative. However, lack of a gold standard for diagnosis (against which culture might be judged) and failure to assess the human immune response are important limitations of prior work. In this pilot study, we aimed to develop a criterion standard for research on bacterial cellulitis, to evaluate the sensitivity of procalcitonin for bacterial cellulitis, and to use gene expression analysis to find other candidate diagnostic markers. Methods We classified lesions via biopsies, 16s rRNA gene detection, culture, and histopathology. We quantified procalcitonin expression in blood. We also used Nanostring technology to quantify transcription of immunomodulators that may distinguish cases from inflamed controls. Results Of 28 participants, 15 had a clinical diagnosis of cellulitis, six had a diagnosis of non-infectious dermatitis, and seven were normal volunteers. Of the “cellulitis” patients, three (20%) had pathogens isolated, and were designated confirmed cases. Procalcitonin was undetectable in all three. HLA-DQA1 was expressed 34-fold more in confirmed cases vs. controls (fold change of geometric mean). Heat maps depicting multiplex gene expression analysis revealed a distinct profile of gene expression in confirmed cases relative to comparators. Conclusions Most “cellulitis” patients had microbiologically-negative biopsies. Procalcitonin was undetectable, and HLA-DQA1 elevated, in confirmed bacterial cases. Multivariable transcriptomic profiling results supported our algorithm’s ability to identify patients with true bacterial cellulitis. A larger sample may allow discovery of an immunological signature capable of distinguishing bacterial cellulitis from its mimics in clinical practice. PMID:27656884

    2016-06-01

    Tick-borne illnesses have diverse biological and clinical features that make recognition and appropriate treatment challenging. Arthropod-transmitted (ticks, fleas and deer flies) tularaemia remains a concern worldwide. Generally, two kinds of tularaemia manifestations, namely ulceroglandular and glandular infections, can arise from the bite of an infected arthropod vector. If the ulceroglandular or glandular form is not treated, suppuration can arise from the gland. In addition, cellulitis is rarely observed around the ulcers. In our case, with the knowledge of tick exposure to the scalp, tularaemia was not initially considered for facial cellulitis without regional lymphadenopathy and also due to apparent failure to respond to doxycycline and gentamicin therapy. Serological confirmation in the late stages of the disease suggests the importance of clinical suspicion in such rare conditions. PMID:27367325

    The US Food and Drug Administration has scrutinized clinical trial methodology in cellulitis, partly because the definition and timing of cure are debatable. We analysed the validity of telephone self-report as a proxy for in-person follow up in a cellulitis treatment trial comparing cephalexin alone with cephalexin-plus-trimethoprim/sulfamethoxazole. Our results demonstrate poor agreement between these two methods of outcome determination and have implications for future cellulitis clinical trial design and clinical management. PMID:25882364

    Acute apical abscesses and cellulitis are severe endodontic diseases caused by opportunistic bacteria with possible co-infection with latent herpesviruses. The objectives of this study are to identify herpesviruses, including human cytomegalovirus (HCMV), Epstein-Barr virus (EBV), herpes simplex virus-1 (HSV-1) and Varicella zoster virus (VZV), in patients (n=31) presenting with acute apical abscesses and cellulitis of endodontic origin. Primary and nested polymerase chain reaction (PCR) was conducted using virus-specific primers and DNA isolated from cell-free abscess fluid. From patients exhibiting concurrent spontaneous pain (n=28), nine abscesses contained HCMV, two abscesses contained EBV, one abscess contained HSV-1, and no abscesses contained VZV. Control PCR using genomic or recombinant templates demonstrated detection limits to a single genomic copy of HCMV, 100 genomic copies for EBV, and 1-10 copies for HSV-1, with no cross-amplification between herpesviral DNA targets. Nested PCR was required for detection of herpesviral DNA in the abscess specimens, indicating that these viruses were present in low copy number. Filtration of abscess specimens and virus transfer experiments using human fibroblastic MRC-5 cells confirmed the presence of HCMV particles in several abscess specimens. We conclude that herpesviruses are present, but not required for development of acute apical abscesses and cellulitis of endodontic origin. PMID:19166769

    Periorbital cellulitis is a relatively common ocular disease in the pediatric population. Early diagnosis of this disease with a prompt intervention is critical to avoid vision and life-threatening complications. In the last years, medical therapy has been expanding for the treatment of orbital cellulitis, instead of the standard surgical approach. The purpose of this study was to describe the outcome of treatment with intravenous antibiotic of periorbital cellulitis in children. A retrospective review of all children admitted with periorbital cellulitis in our hospital between January 2002 and July 2013 was conducted. Cases were divided in two subgroups, pre-septal and post-septal infection. The demographics, clinical findings, treatment and outcomes were analyzed. In total 110 children were included, 93 with pre-septal and 17 with post-septal cellulitis. The mean age was 3.5 years in children with pre-septal cellulitis and 5.5 years in those with post-septal cellulitis (p = 0.149). For both subgroups the most common predisposing factor was sinusitis. Intravenous antibiotic therapy was successful in all except one patient with an orbital abscess who required surgical intervention. In our study complete recovery was achieve in all (except for one) children with periorbital cellulitis treated with intravenous antibiotics only. PMID:27192038

    Dacryocystitis-related orbital cellulitis is a relatively rare condition, and large case series of this clinical entity have been reported. This study was undertaken to identify a larger cohort of patients with this ailment, with the intent of defining its clinical and microbiologic features. Case logs from four institutions were reviewed to identify patients that suffered from dacryocystitis-related orbital cellulitis. A retrospective chart review was then performed to identify clinical features, management strategies, microbiologic features, and outcomes. A dedicated statistical software package was utilized to identify correlations between these variables. 13 patients (7 females, 6 males; mean age = 57.2 years, range = 7-89 years) were identified. One patient carried a diagnosis of immunosuppressive disease. All patients underwent emergent surgical drainage and received intravenous antibiotics. Primary acquired nasolacrimal duct obstruction was found to be the underlying etiology in nine cases (69.2%), whereas four patients suffered from specific causes of their obstructions. An average of 1.07 organisms/patient (standard deviation = 0.49 organisms/patient) were recovered from microbiologic cultures, and Gram-positive bacteria represented the majority of cultured organisms. All patients experienced either stable or improved vision upon discharge. The relationships between a specific etiology and the possibility of vision loss or the number of organisms cultured, between the number of organisms cultured and vision loss, and immunosuppression and vision loss or the number of organisms cultured were all not statistically significant (p > 0.05). Dacryocystitis-related orbital cellulitis most commonly occurs in adult patients who do not carry immunosuppressive diagnoses and suffer from primary obstructions. Multiple microbiologic species may cause this problem, although Gram-positive organisms are most common. With appropriate management, stable or improved vision

    Cryptococcus neoformans is a common fungus found throughout the environment that causes opportunistic disease in immunocompromised individuals. Infection of humans with C neoformans usually manifests as lung disease through inhalation of spores or meningoencephalitis by involvement of the central nervous system. Rarely, dissemination in the form of cutaneous lesions can occur in individuals with long term immunosuppression. We present a patient with C. neoformans manifesting as cellulitis with focal segmental glomerulosclerosis treated with corticosteroids. Because of the mortality associated with disseminated cryptococcosis, early identification, especially of atypical cutaneous presentations is critical from a dermatological perspective.

Upon presentation, she was immediately started on broad-spectrum antibiotics and underwent surgical incision and drainage of the lacrimal sac abscess but never regained vision. There are 4 cases in the literature of permanent severe vision loss from acute dacryocystitis. Prompt diagnosis and close monitoring of acute dacryocystitis are therefore essential to prevent extension into the orbit and possible optic nerve compromise. PMID:27803829

    Objective To evaluate the prevalence and associated factors involved in cellulitis with lymphangitis among a group of Korean patients who were being treated for lymphedema. We present our epidemiologic research and we also report a systematic review of these types of cases. Methods This was a retrospective medical record study among 1,246 patients diagnosed with lymphedema. The study was carried out between January 2006 and December 2012 at the Kosin University Gospel Hospital and Seoul National University Bundang Hospital. Cases were examined for onset time, affected site, seasonal trend, and recurrence pattern of lymphedema, lymphangitis, and cellulitis. We also evaluated the history of blood-cell culture and antibiotic use. Results Ninety-nine lymphedema patients experienced complications such as cellulitis with accompanying lymphangitis. Forty-nine patients had more than two recurrences of cellulitis with lymphangitis. The incidence and recurrence of cellulitis with lymphangitis were significantly higher in the patients with lower-extremity lymphedema. There was a significant trend toward higher cellulitis prevalence in the lower-extremity lymphedema group according to the time of lymphedema onset. Among the cellulitis with lymphangitis cases, 62 cases were diagnosed through blood-cell culture; 8 of these 62 cultures were positive for β-hemolytic streptococci. Conclusion The prevalence rate of cellulitis with lymphangitis in patients with lymphedema was 7.95%, and the prevalence of recurrent episodes was 3.93%. Especially, there was high risk of cellulitis with lymphangitis after occurrence of lower-extremity lymphedema with passage of time. Lymphedema patients should be fully briefed about the associated risks of cellulitis before treatment, and physicians should be prepared to provide appropriate preventive education. PMID:27152284

    We report a case of acute neck cellulitis and mediastinitis complicating a continuous interscalene brachial plexus block. A 61-yr-old man was scheduled for an elective arthroscopic right shoulder rotator cuff repair. A continuous interscalene block was done preoperatively and 20 mL of 0.5% bupivacaine and 20 mL of 2% mepivacaine were injected through the catheter. Postoperative analgesia was provided by a continuous infusion of bupivacaine, 0.25% at 5 mL/h for 39 h using a 240-mL elastomeric disposable pump. The day after surgery, the patient complained of neck pain. The analgesic block was not fully effective. He was discharged home. Three days later, the patient was readmitted with neck edema and erythema, fever and fatigue. Neck ultrasonography and computed tomographic scan revealed an abscess of the interscalene and sternocleidomastiod muscles and cellulitis, as well as acute mediastinitis. Two blood cultures and surgical samples were positive for Staphylococcus aureus. The infection was treated with surgery, the site was surgically debrided, and a 2-mo course of vancomycin, imipenem, and oxacilline. The technique of drawing local anesthetic from the bottle and filling the elastomeric pump was the most likely cause of infection. This case emphasizes the importance of strict aseptic conditions during puncture, catheter insertion, and management of the local anesthetic infusate. PMID:18806062

    Military trainees are at high risk for skin and soft-tissue infections (SSTIs). Although Staphylococcus aureus is associated with purulent SSTI, it is unclear to what degree this pathogen causes nonpurulent cellulitis. To inform effective prevention strategies and to provide novel insights into SSTI pathogenesis, we aimed to determine the etiology of SSTI in this population. We conducted a prospective observational study in US Army Infantry trainees with SSTI (cutaneous abscesses and cellulitis) from July 2012 through December 2014. We used standard microbiology, serology, and high-throughput sequencing to determine the etiology of SSTI. Furthermore, we compared purported risk factors as well as anatomic site colonization for S. aureus. Among 201 SSTI cases evaluated for SSTI risk factors, cellulitis was associated with lower extremity blisters (P = 0.01) and abscess was associated with methicillin-resistant S. aureus (MRSA) colonization (P<0.001). Among the 22 tested cellulitis cases that were part of the microbiome analysis, only 1 leading edge aspirate was culturable (Coagulase-negative Staphylococcus). Microbiome evaluation of aspirate specimens demonstrated that Rhodanobacter terrae was the most abundant species (66.8% average abundance), while abscesses were dominated by S. aureus (92.9% average abundance). Although abscesses and cellulitis share the spectrum of clinical SSTI, the bacterial etiologies as determined by current technology appear distinct. Furthermore, the presence of atypical bacteria within cellulitis aspirates may indicate novel mechanisms of cellulitis pathogenesis. Clinical Trials Registration: NCT01105767. PMID:27780238

    Primary cutaneous nocardiosis is an infrequent infection among children, generally affecting immunocompromised hosts. It is caused by Gram positive bacteria, partially alcohol and acid resistant which are saprophytes of the soil, water and organic matter. In most cases the causal agent enters through inhalation, and hematogenous dissemination may occur mainly among the immune compromised patients. Direct cutaneous inoculation is less frequent, especially among children. We report an 8-year old female who lives in an urban house with a small garden, who presented with an ulcer on her right shin accompanied by surrounding cellulitis, pain, swelling and fever. The patient's medical history was unremarkable, with no exposure to animals or travelling, except for rafting on the Jordan River the previous week. Culture from the ulcer grew Nocardia brasiliensis, and she recovered after 8 weeks of therapy with trimethoprim-sulphamethoxazole. PMID:23350294

    Corals are the marine organism that belongs to the phylum Cnidaria, and are one of the common causes of superficial injury in the marine environment. In addition to acute reactions such as burning or stinging pain and erythema, coral injuries may present with complications such as foreign body reactions, bacterial infections, and/or localized eczematous reactions. A 23-year-old male presented with an erythematous edematous tender patch with centrally grouped vesicles on the left ankle; the injury had occurred during skin-scuba diving 2 days before. A biopsy of the lesion treated with hematoxylin-eosin stain showed epidermal necrosis with subepidermal blisters and neutrophilic panniculitis. Herein we report a case of cellulitis caused by the nematocyst stings of corals.

    A retrobulbar abscess/cellulitis occurred in a Yorkshire Terrier dog. The clinical signs were exophthalmos, prolapsed nictitating membrane and purulent ocular discharge. Ultrasonography showed a marked soft tissue swelling of the retrobulbar tissues as well as echogenic parallel lines between the globe and the medial orbital rim. Surgical exploration of the orbit was performed and no foreign body was found. The pterygopalatine fossa was incised and therapeutic retrobulbar drainage attempted. A drain was placed to encourage ventral drainage of the abscess. Anaerobic cultures revealed heavy growth of gram negative rods (prevotella bivia and prevotella buccae were isolated). Recovery was successful but subsequent treatment for keratoconjunctivitis sicca was necessary. A full recovery of tear production occurred after several weeks.

    We describe a case of toxic scarlet fever in a healthy adult with streptococcal cellulitis of the right elbow as a result of skin abrasion. The clinical picture mimicked that of drug eruption after treatment of cellulitis with antibiotics. Among the five cases of scarlet fever complicating cellulitis, including the present one, reported in the English literature, four had severe systemic complications and two died. As a result of re-emergence of invasive streptococcal infections, clinicians should be aware of the differential diagnosis of scarlet fever in patients presenting with cellulitis and skin rash. Early clinical diagnosis is crucial to exclude drug eruptions, prompt initiation of antibiotic treatment, and prevention of the potentially fatal outcome.

    Dissecting cellulitis is an uncommon, chronic, progressive suppurative disease of unknown etiology. It is characterized by painful papules and nodules, interconnecting sinus tracts, purulent drainage, and scarring alopecia. This disease predominately affects young black men, but is rarely reported in white males. The refractory nature of this process makes treatment difficult. We report a case of dissecting cellulitis in a white male, which responded to oral isotretinoin. PMID:11204602

    In neutropenic patients cellulitis caused by Gram-negative organisms may prove difficult to control and cause considerable tissue damage. Phenoxyethanol has activity against a range of bacteria, including Pseudomonas aeruginosa, and is absorbed by intact skin. Three severely neutropenic patients are described in whom cellulitis failed to respond to appropriate intravenous antibiotics. However the topical application of phenoxyethanol solution gave prompt local control. This cheap and nontoxic agent may give dramatic improvement in this difficult clinical situation.

    2016-09-01

    Eosinophilic cellulitis (Wells syndrome) is a rare inflammatory skin disease defined by erythematous, tender, sometimes urticarial plaques, possibly with vesicles and bullae, and granulomatous eosinophilic infiltrates in the dermis. Usually the disease has a benign course with spontaneous remission within a few weeks. Nevertheless, recurrences are quite frequent and may occur for several years. The objective of this study was to review the so far reported treatment options for Wells syndrome in a systematic manner. This systematic review is based on a search on Medline, Embase and Cochrane Central Register for English and German articles from 1970 to 2015. Advices on the treatment of Wells syndrome are limited predominately to case reports or to small case series. There are no randomized controlled trials, and control groups are missing. A variety of treatment options for Wells syndrome were reported including topical and systemic corticosteroids, antihistamines, cyclosporine, dapsone, azathioprine, griseofulvin, doxycycline, minocycline, antimalarial medications, oral tacrolimus/topical tacrolimus, sulfasalazine, interferon alpha and gamma, TNF alpha inhibitors, colchicine and PUVA therapy. As well-designed, randomized controlled trials are missing, no guidelines for the treatment of this disease can be given. Due to the small number of patients and the frequent misdiagnosis of this clinical entity, the aim of this systematic overview is to call attention to this rare condition and to help clinicians to diagnose and treat Wells syndrome effectively. Due to the good prognosis and tendency to resolve, systemic treatment should be limited to cases resistant to local therapy or with widespread lesions. PMID:27357601

  12. Neonatal retroauricular cellulitis as an indicator of group B streptococcal bacteremia: a case report

    PubMed Central

    2009-01-01

    Introduction The relation between cellulitis and Group B streptococcus infection in newborns and small infants was first reported during the early 1980s and named cellulitis-adenitis syndrome. We report a case of a neonate with cellulitis-adenitis syndrome in an unusual location (retroauricular). Case presentation A 21-day-old Caucasian female infant was brought to the emergency department with fever, irritability and a decreased appetite. Physical examination revealed erythema and painful, mild swelling in the right retroauricular region. The blood count and C-reactive protein level were normal. She was treated with ceftriaxone. The fever and irritability were resolved after 24 hours, and the cellulitis was clearly reduced after two days of hospitalization. Blood culture yielded Group B streptococcus. Conclusion A thorough evaluation must be done, and lumbar punctures for infants with cellulitis must be considered. We emphasize the lack of data about acute phase reactants to predict bacteremia and meningitis and to adjust the duration of parenteral antibiotic therapy to address this syndrome. PMID:20062760

    The incidence of deep vein thrombosis (DVT) in patients with erysipelas and cellulitis of the lower extremities is unknown. As such, the indication and efficacy of prophylactic anticoagulation for prevention of DVT in these patients is unclear. The main goal of this review is to provide an estimate of the incidence of DVT in erysipelas and cellulitis based on existing literature. A comprehensive search of the electronic sources: MEDLINE, EMBASE, CINAHL, LILAC and Cochrane without any language limitation was performed from 1950 to April 2011 for articles focused on the occurrence of DVT in cellulitis or erysipelas of the lower extremities. The selected studies were divided into two groups according to presence or absence of systematic investigation for DVT. Those studies in which the patients received prophylactic or therapeutic anticoagulants before a diagnosis of DVT were excluded. The reported incidence rate of DVT in patients with erysipelas or cellulitis of the lower extremities is highly variable, ranging from 0 to 15%. In this review, the overall incidence rates of DVT in studies with and without systematic investigation for thromboembolism were 2.72% (95% CI: 1.71-3.75%) and 0.68% (95% CI: 0.27-1.07%), respectively. Given the low reported overall incidence of DVT, neither routine prophylactic anticoagulation nor systematic paraclinical investigation for DVT is indicated in low risk patients with erysipelas or cellulitis of the lower extremities. DVT should still be considered in patients with high pretest probability or other thromboembolic risk factors.

    Hypersensitivity reactions to aluminum are rare. Sensitization has been reported during the continuous application of aluminum-containing antiperspirants or after the injection of aluminum-adsorbed vaccines and allergen extracts containing aluminum. We report a rare case of a nonhealing ulcer at the site of an accidental molten aluminum burn that showed changes of eosinophilic cellulitis and panniculitis histologically. This process was followed by a generalized vesicular and pustular id reaction. The reactions resolved after 1 month of systemic corticosteroid therapy. Two months later, there was a relapse with bullae over the burn scar, accompanied by a pruritic oozing rash on the ears and face; the lesions were controlled again with systemic corticosteroid treatment. The clinicopathologic features suggest that the eosinophilic cellulitis with panniculitis and id reaction in the present case represents an unusual allergic reaction to aluminum. Aluminum allergy may be considered as a possible underlying process in the setting of eosinophilic cellulitis with panniculitis and id reaction.

    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.

    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.

    Dissecting cellulitis of the scalp, or perifolliculitis capitis abscedens et suffodiens, is an uncommon chronic suppurative disease of the scalp manifested by follicular and perifollicular inflammatory nodules that suppurate and undermine, forming intercommunicating sinuses, and leading to scarring alopecia. Treatment generally fails to obtain a permanently successful result; thus, many therapeutic options have been proposed. We report 4 cases of dissecting cellulitis of the scalp successfully treated with oral rifampicin and oral isotretinoin. To our knowledge, this is the first report of oral rifampicin used concomitantly with oral isotretinoin in this disease entity. We also present a brief review of the literature on the topic.

    Objective The purpose of this case report is to describe the presentation of cellulitis in a 16-month-old boy to a chiropractic clinic. Clinical Features The patient presented with nontraumatic, sudden onset of nonpurulent erythema on the right knee. A plain film radiograph of the knee showed a 40-mm thickening of the anterior knee. A diagnosis of cellulitis was rendered based on the presentation of the rapidly spreading erythema and radiographically confirmed findings. Intervention and Outcome The patient was immediately referred to the local emergency room. The patient was hospitalized, treated with clindamycin and amoxicillin for 3 days, and then discharged. The patient’s pediatrician discontinued clindamycin treatment at the posthospitalization follow-up. Two weeks after treatment was discontinued, the patient was diagnosed with recurrent cellulitis. Conclusion This case demonstrated that for this young patient with cellulitis of the knee, timely recognition and referral, together with patient or parent education and immediate treatment, were essential to a successful outcome.

    The purpose of this investigation was to analyze the clinical and epidemiological aspects of all cases of erysipelas and infectious cellulitis admitted to a tertiary hospital during a period of five years. All patients admitted with the main diagnosis of erysipelas or cellulitis to the Department of Dermatology of the author's institution from January 2005 to May 2010 were included. Seventy patients were identified and their medical records were retrospectively reviewed so as to record the epidemiological and clinical data. Univariate and multivariable analyses were performed to analyze variables that predicted longer length of stay. The frequency of cellulitis in the lower limbs was higher in men and patients older than 65 years. Moderate/severe cellulitis in patients with basal comorbidity followed by a poor response to oral antibiotic therapy for 48 h were the most common reasons for admission. At arrival, four patients had abscessed areas. Fourteen patients developed local complications and 18 cases developed general in-hospital complications. Most patients improved or were healed with intravenous amoxicillin-clavulanate 1 g-200 mg/8 h. Intravenous amoxicillin-clavulanate 1 g-200 mg/8 h may be a good choice for empiric treatment in our setting. The development of in-hospital complications and the need for changing empiric antibiotic therapy were significant and independent variables associated with longer length of stay.

    A 31-year-old woman presented with a subcutaneous cellulitis which occurred within four hours following a minor wound of a knee. This very short delay could be explained neither by the health state, nor the mechanism of injury, nor the bacteria usually responsible for such a cellulitis. Considering the clinical characteristics (high gas production) and the professional context (wine cellar employee), Saccharomyces cerevisiae, a yeast used for wine or bread production, may explain this complication.

    The prevalence of mycobacterial infection has increased in recent years, especially in patients immunocompromised due to autoimmune disease, malignancy and AIDS. Mycobacterium kansasii infection most commonly presents as tuberculosis-like pulmonary disease. We report the case of a 38-year-old woman with systemic lupus erythematosus (SLE) who developed cellulitis over the left lower leg and had poor response to antibiotics. Two months before this admission, she had sustained a small wound over the right pretibial area and had noticed erythematous swelling after swimming at the beach. Pathologic examination of biopsied tissue showed acid-fast bacilli, and culture yielded M. kansasii. The cellulitis improved gradually during treatment with antimycobacterial agents for 1 year. This case emphasizes the possibility that cutaneous M. kansasii infection may occur in an immunocompromised patient and that exposure to contaminated water is a possible source. With early diagnosis, the response to an antimycobacterial multidrug regimen is usually satisfactory.

    Dissecting cellulitis (also called perifolliculitis capitis abscedens et suffodiens) manifests with perifollicular pustules, nodules, abscesses and sinuses that evolve into scarring alopecia. It predominantly occurs in African American men between 20-40 years of age, but can occasionally affect other races and women too. Associated musculoskeletal findings are sometimes reported. When it occurs with acne conglobata, hidradenitis suppurativa, and pilonidal cysts, the syndrome is referred to as the follicular occlusion triad or tetrad. Its course is chronic and relapsing, and treatment is often difficult. Medical therapies include isotretinoin, antibiotics, and prednisone. Destructive therapies include X-ray therapy, surgical excision, and skin grafting. Laser epilation of hair follicles is a promising new therapy for dissecting cellulitis. PMID:12639466

    We describe 3 patients with rheumatoid arthritis who presented with diffuse pain, swelling, and erythema of the distal aspect of the lower extremity, suggestive of either cellulitis or thrombophlebitis, but were found to have insufficiency fractures of the distal tibia. The value of technetium-99m diphosphonate bone scintigraphy in the early recognition of these fractures and a possible explanation for the associated inflammatory symptoms are discussed.

    Cellulitis in the setting of lymphedema is an uncommon but clinically important presentation to the emergency department. Stagnant lymph is an ideal medium for bacterial growth and progression can be rapid due to decreased ability to fight infection in the affected area. Infections are commonly caused by gram-positive cocci, though blood cultures are often negative. Treatment should be aimed at rapid initiation of antibiotics targeting these species. There may be a role for antibiotic prophylaxis in recurrent cases. PMID:26171259

    An advanced analysis code, ARKAS cellule, has been developed to determine the core distortion and the mechanical behavior of fast reactors. In this code, each hexagonal subassembly duct is represented by a folded thin plate structure divided into a user-specified number of shell elements so that the interduct contact forms and the cross-sectional distortion effect of each duct are properly taken into account. In this paper, the numerical model of the ARKAS cellule code is introduced, and the analytical results for two validation problems are presented. From a single duct compaction analysis, the first validation problem, it is clarified that the new analytical model is applicable to simulating the change of duct compaction stiffness that depends on the loading conditions such as the loading pad forms and the number of contact faces. The second validation analysis has been conducted by comparison with the experimental values obtained by the National Nuclear Corporation Limited in the United Kingdom using the core restraint uniplanar experimental rig (CRUPER), an ex-reactor rig in which a cluster of 91 short ducts is compressed by 30 movable peripheral rams toward the center of the cluster in seven stages. The analysis clarified that the predictions obtained using ARKAS cellule agree well with the measured ram loads and interwrapper gap widths during the compaction sequence. One may conclude that ARKAS cellule is valid for quantitative analysis of the core mechanical behavior and will be particularly useful for the evaluation of transient deformation of core assemblies during accidents in which the distortion of loading pads have important effects on obtaining favorable reactivity feedback.

    Follicular mycosis fungoides (MF) is a rare variant of cutaneous T-cell lymphoma (CTCL) in which malignant lymphocytes preferentially infiltrate hair follicles. This report describes a patient with follicular mycosis fungoides presenting in a manner similar to dissecting cellulitis of the scalp with nonhealing, draining nodular lesions. Follicular mucinosis associated with folliculotropic mycosis fungoides resulted in follicular disruption and deep dissecting cellulitis. Large-cell transformation of CTCL was present in the initial diagnostic scalp and axillary lymph node specimens. The patient died from progressive CTCL 9 months following initial diagnosis despite electron beam radiation, topical mechlorethamine, interferon-alpha, and systemic chemotherapy. This case indicates that large-cell transformation of folliculotropic mycosis fungoides is an aggressive form of CTCL, and that folliculotropic mycosis fungoides can give rise to lesions which resemble dissecting cellulitis of the scalp. Upregulation of intercellular adhesion molecule-1 (ICAM-1) on follicular epithelium adjacent to lymphocyte function-associated antigen-1 (LFA-1)-positive folliculotropic lymphoma cells in this report provides insight into lymphocyte homing mechanisms in folliculotropic MF.

    Tinea capitis in postpubertal patients is unusual and may be misdiagnosed as dissecting cellulitis. We report a case of a healthy 19-year-old Hispanic male presenting with a 2-month history of a large, painful subcutaneous boggy plaque on the scalp with patchy alopecia, erythematous papules, cysts and pustules. Although initially diagnosed as dissecting cellulitis, potassium hydroxide evaluation (KOH preparation) of the hair from the affected region was positive. A punch biopsy of the scalp demonstrated endothrix consistent with tinea capitis, but with a brisk, deep mixed inflammatory infiltrate as can be seen with chronic dissecting cellulitis. Fungal culture revealed Trichophyton tonsurans, and a diagnosis of inflammatory tinea capitis was made. The patient was treated over the course of 17 months with multiple systemic and topical antifungal medications, with slow, but demonstrable clinical and histopathological improvement. A rare diagnosis in adults, clinicians should have a high index of suspicion for this condition in an adult with an inflammatory scalp disorder not classic for dissecting cellulitis or with a recalcitrant dissecting cellulitis. Prompt, appropriate diagnosis and treatment is necessary to prevent the long-term complications of scarring alopecia. PMID:23582018

    A case of fulminant dissecting cellulitis of the scalp in a fifteen-year-old African American male is reported. The presentation was refractory to standard medical treatment such that treatment required radical subgaleal excision of the entire hair-bearing scalp. Reconstruction was in the form of split-thickness skin grafting at the level of the pericranium following several days of vacuum-assisted closure dressing to promote an acceptable wound bed for skin grafting and to ensure appropriate clearance of infection. Numerous nonsurgical modalities have been described for the treatment of dissecting cellulitis of the scalp, with surgical intervention reserved for patients refractory to medical treatment. The present paper reports a fulminant form of the disease in an atypical age of presentation, adolescence. The pathophysiology, etiology, natural history, complications and treatment options for dissecting cellulitis of the scalp are reviewed, and the authors suggest this method of treatment to be efficacious for severe presentations refractory to medical therapy.

    Non-traumatic nasal septal abscess is rare, commonly seen in patients with poor immunity, and presents as isolated nasal septal abscess. Further, nasal septal abscess complicated with acute sinusitis is rather rare. Very little literature has been generated for non-traumatic nasal septal abscess complicated with acute sinusitis in healthy patients. Prompt diagnosis and adequate treatment will help to prevent the complications associated with nasal septal abscess such as saddle nose and intracranial involvement. Herein, to our knowledge, we present the first case involving an otherwise healthy little girl with nasal septal abscess complicated with acute sinusitis and facial cellulitis.

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

    The authors present the case of a 30-year-old male patient with a severe and long-standing dissecting cellulitis of the scalp. The disease did not respond to conventional treatment, including oral antibiotics, isotretinoin, and prednisolone. Quality of life was significantly impaired. After introduction of anti-tumor necrosis factor-alpha treatment (infliximab), the malodorous discharge stopped, inflammation was reduced significantly, nodules became flat, and pain decreased. The treatment was well tolerated although he developed a temporary psoriasiform rash after the second intravenous infusion. In conclusion, anti-tumor necrosis factor-alpha treatment is a new therapeutic option in this severe and recalcitrant disorder. PMID:22708007

    Dissecting cellulitis of the scalp, or Hoffman's disease, is a rare dermatologic condition characterized by recurrent pustules and sinus tract formation leading to scarring and alopecia. Medical management includes the use of corticosteroids, antibiotics, isotretinoin, and adalimumab. In cases where the disease is severe, refractory, and intractable, surgery is an option. We report two cases of Hoffman's disease, where medical management failed to achieve remission. Surgical treatment was undertaken with complete resection of the affected scalp in staged procedures with subsequent split-thickness skin grafting for reconstruction. Surgery achieved both disease remission and excellent aesthetic outcomes in both patients. PMID:26966606

    Agrobacterium radiobacter is a gram-negative aerobic bacillus that has been reported as a cause of disease only 36 times in the literature. More than half of the patients (25) have had bacteremia. Peritonitis, urinary tract infection, endocarditis, and one case of cellulitis associated with bacteremia have also been reported. Infection is often associated with immunosuppression and the presence of a plastic foreign body, such as central venous catheters, nephrostomy tubes, intraperitoneal catheters, and prosthetic cardiac valves. We present apparently the first case of A radiobacter causing myositis after influenza virus vaccination.

    Centipede bites occurring in tropical countries are rare, however vigilance must be exercised during activities in the open air and dwellings should be checked in the event of rain. The bite is very painful and can be accompanied by generalised signs. An initial wound disinfection and a check of antitetanus vaccination status is all that is usually needed to ensure an uneventful outcome. There are however, rare cases where local toxicity and a bacterial super-infection, often with Gram+ cocci, can lead to a cellulitis or even necrotizing fasciitis of the hand. The diagnosis of a centipede bite can be made by the double marks made by the fangs. Wound debridement and antibiotics led to a good outcome in both our cases.

The infection occurred in an immunocompetent man with diabetes mellitus type II. Apparently, the infection was acquired in a tropical country and once the patient was in Spain the infection progressed causing nail detachment (onychomadesis). Seven months later a relapse that affected the left toenail occurred. The patient was treated topically with chemical toenail avulsion contained 40% urea associated with bifonazole followed by ciclopirox-olamine nail lacquer for 12 months. Complete cure without relapse was observed after 10 years of follow-up. In vitro antifungal susceptibility study demonstrated that two of the recovered isolates were both resistant to itraconazole and voriconazole.

    In recent years, the market for resorbable injectables has been steadily expanding. The European Community's seal of approval (CE) is a sufficient guaranty to get them distributed. These injectables do not require official approval because they are considered to be "implantable medical devices" and not medicines. Macrolane(®)is a hyaluronic acid in gel form (NASHA [non-animal stabilized hyaluronic acid]) and has been on the French market since 2007. It can be injected into all areas except the face. It is highly cross-linked which, while slowing its absorption into the body, can also leave long-lasting residues. We report the first case of cellulitis after injection into the calf by a practitioner in his office.

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

    Leprosy is aneasily recognizable disease due to its dermato-neurological manifestations. It must be present in the physician’s diagnostic repertoire, especially for those working in endemic areas. However, leprosy reaction is not always easily recognized by non-dermatologists, becoming one of the major problems in the management of patients with leprosy, as it presents clinical complications characterized by inflammatory process, accompanied by pain, malaise and sometimes the establishment or worsening of the patient’s disabilities. We report the case of a patient with type-1 periorbital reaction admitted to the hospital, diagnosed and treated as facial cellulitis, whose late diagnosis may have contributed to the appearance or worsening of facial neuritis.

    2016-01-01

    Background. Skin and soft tissue infections are common reasons for medical care. Use of broad-spectrum therapy and costs have increased. Assessment of early treatment response has been given a central role both in clinical trials and everyday practice. However, there is a paucity of data on the dynamics of response, causes of early nonresponse, and how early nonresponse affects resource use and predicts outcome. Methods. We prospectively enrolled 216 patients hospitalized with cellulitis. Clinical and biochemical response data during the first 3 days of treatment were analyzed in relation to baseline factors, antibiotic use, surgery, and outcome. Multivariable analysis included logistic lasso regression. Results. Clinical or biochemical response was observed in the majority of patients the day after treatment initiation. Concordance between clinical and biochemical response was strongest at days 2 and 3. Female sex, cardiovascular disease, higher body mass index, shorter duration of symptoms, and cellulitis other than typical erysipelas were predictors of nonresponse at day 3. In contrast, baseline factors were not predictive of clinical failure assessed posttreatment. Among cases with antibiotic treatment escalation by day 2, 90% (37/41) had nonresponse at day 1, but only 5% (2/40) had inappropriate initial therapy. Nonresponse at day 3 was a predictor of treatment duration >14 days, but not of clinical failure. Conclusions. Nonpharmacological factors had a major impact on early response dynamics. Delayed response was rarely related to inappropriate therapy but strongly predictive of early treatment escalation, suggesting that broadening antibiotic treatment may often be premature.

    This article advocates the need for early incision and drainage of periorbital abscesses. We report a case of a 1.5-month-old neonate with orbital cellulitis and periorbital abscess, which had rapidly developed over a period of 3 days. Treatment history revealed methicillin-resistant Staphylococcus aureus sepsis treated with intravenous vancomycin, and incision and drainage of abscesses at multiple sites (left parotid region, upper and lower limbs). A small swelling noted on the left temporal region on discharge from the hospital was treated with oral cotrimoxazole. However, it spread rapidly to involve the periorbital tissue and the bones of the orbital walls to form a periorbital abscess and orbital cellulitis. PMID:25899513

    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.

    Suspected Streptomyces spp infections were identified in 4 cats at UC Davis Veterinary Medical Teaching Hospital between 1982 and 2011. Three had ulcerated, dark red mycetomas involving the dermis, subcutis, and fascia with fistulous tracts and/or regional lymphadenopathy. One cat had pyogranulomatous mesenteric lymphadenitis. Granulomatous inflammation in all cats contained colonies of Gram-positive, non-acid-fast organisms. All 4 cats failed to respond to aggressive medical and surgical treatment and were euthanized. Laser capture microdissection (LCM) was used to selectively harvest DNA from the affected formalin-fixed, paraffin-embedded (FFPE) tissues. Cloned amplicons from LCM-derived tissue confirmed the presence of Streptomyces spp in the dermatitis cases. Amplicons from the remaining cat with peritoneal involvement aligned with the 16S ribosomal RNA gene for Actinomycetales. Usually considered a contaminant, Streptomyces spp can be associated with refractory pyogranulomatous dermatitis and cellulitis in cats with outdoor access. LCM is useful in the diagnosis of bacterial diseases where contamination may be an issue.

    We report a 4-year-old boy with cellulitis and scarlet fever due to streptococcal infection following the onset of varicella. He developed a painful ulcer and subcutaneous induration on the left shoulder and a small, light-red-colored rash on the trunk at approximately the same time as the development of vesicles over the entire body. Streptococcus pyrogenes was isolated from samples from the posterior intranasal space and the ulcer on the shoulder. The clinical symptoms improved with the administration of antibiotics and intravenous drip infusion, but it took approximately one month from the first visit for the subcutaneous induration to disappear and the ulcer to heal with epithelialization. The complication of secondary streptococcal infection in varicella is relatively rare in Japan, but in Western countries there have been many reported cases of life-threatening necrotizing fasciitis and necrotizing pyomyositis due to secondary streptococcal infection following varicella. Close attention should be paid to streptococcal infection as a complication of varicella.

    Suspected Streptomyces spp infections were identified in 4 cats at UC Davis Veterinary Medical Teaching Hospital between 1982 and 2011. Three had ulcerated, dark red mycetomas involving the dermis, subcutis, and fascia with fistulous tracts and/or regional lymphadenopathy. One cat had pyogranulomatous mesenteric lymphadenitis. Granulomatous inflammation in all cats contained colonies of Gram-positive, non-acid-fast organisms. All 4 cats failed to respond to aggressive medical and surgical treatment and were euthanized. Laser capture microdissection (LCM) was used to selectively harvest DNA from the affected formalin-fixed, paraffin-embedded (FFPE) tissues. Cloned amplicons from LCM-derived tissue confirmed the presence of Streptomyces spp in the dermatitis cases. Amplicons from the remaining cat with peritoneal involvement aligned with the 16S ribosomal RNA gene for Actinomycetales. Usually considered a contaminant, Streptomyces spp can be associated with refractory pyogranulomatous dermatitis and cellulitis in cats with outdoor access. LCM is useful in the diagnosis of bacterial diseases where contamination may be an issue. PMID:25516065

    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.

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

    Facial cellulitis caused by odontogenic bacterial infection is frequently encountered; however, facial cellulitis caused by Candida albicans infection is rarely found. A patient with oral submucous fibrosis (OSF) and unknown diabetes mellitus (DM) was treated in our out-patient dental clinic by biweekly submucosal injection of 40 mg triamcinolone acetonide into bilateral buccal mucosae plus forced mouth opening performed by the two hands of the clinician. The interincisal distance of the patient improved from 28 to 48 mm after four times of steroid injection. The symptoms and signs of OSF also improved markedly. Unfortunately, facial candidal cellulitis occurred 2 months after the last time of steroid injection treatment. The infection was cured by incision and drainage, intravenous administration of amphotericin B (100 mg once a day for a week), and an appropriate medical control of DM. No recurrence of facial cellulitis was found during the follow-up period of 18 months. To prevent the occurrence of facial cellulitis after a high-dose steroid therapy, some prophylactic procedures should be taken before the initiation of the steroid treatment.

    Dissecting cellulitis of the scalp or dissecting folliculitis also known as "perifoliculitis capitis abscedens et suffodiens" (PCAS), is a rare, severe and distinct dermatological disease. It most probably occurs because of follicular occlusion via hyperkeratosis, having the same mechanism of acnea conglobata and hidradenitis suppurativa. These dermatoses may be associated or may have an isolated evolution. PCAS is one of the primitive cicatricial alopecia of neutrophilic type (with pustules). What is characteristic for the histopathologic picture of the disease is the deep inflammatory infiltrate, placed at the reticular derm or hypoderm level. The initial perifolliculitis evolves towards forming profound abscesses and the destruction of polysebaceous follicles because of granuloma, usually lymphoplasmocitary and with gigantic cells. Here is the case of a 24-year-old male with records of acne conglobata and cicatricial alopecia of the scalp, with relapsed inflammatory nodular lesions on the surface of the alopecic plaques and follicular pustules on their margin. The patient had followed before hospitalizing a systemic treatment with antibiotics (azithromycin, tetracycline, ciprofloxacin, in therapeutic schemes that the patient cannot mention, but anyway of short time) and after that a treatment with retinoids (isotretinoin, 20-30 mg/day, in two successive therapies of one month each). The evolution of the disease under these treatments was with outbreaks and short times of remission of the acne lesions and nodular lesions of the scalp. The clinical diagnosis of PCAS is difficult, especially in the initial stage of the disease, as it was the case of the patient presented here. We underline the importance of a correct history of the disease, of the complete clinical exams and the need of paraclinical investigations (histopathologic exam from the lesional biopsy - microscopy and immunohistochemistry) in order to come with a positive diagnosis of PCAS and a

The patient tolerated and responded well to this new approach without any adverse events. This suggested that topical ALA-PDT could be an effective and safe alternative for DCS patients who were refractory to other conventional therapies. We also reviewed etiology, pathophysiology, natural history and treatment options for DCS. PMID:24284093

    Dans le contexte environnemental actuel, le photovoltaïque bénéficie de l'augmentation des efforts de recherche dans le domaine des énergies renouvelables. Pour réduire le coût de la production d'électricité par conversion directe de l'énergie lumineuse en électricité, le photovoltaïque concentré est intéressant. Le principe est de concentrer une grande quantité d'énergie lumineuse sur des petites surfaces de cellules solaires multi-jonction à haute efficacité. Lors de la fabrication d'une cellule solaire, il est essentiel d'inclure une méthode pour réduire la réflexion de la lumière à la surface du dispositif. Le design d'un revêtement antireflet (ARC) pour cellules solaires multi-jonction présente des défis à cause de la large bande d'absorption et du besoin d'égaliser le courant produit par chaque sous-cellule. Le nitrure de silicium déposé par PECVD en utilisant des conditions standards est largement utilisé dans l'industrie des cellules solaires à base de silicium. Cependant, ce diélectrique présente de l'absorption dans la plage des courtes longueurs d'onde. Nous proposons l'utilisation du nitrure de silicium déposé par PECVD basse fréquence (LFSiN) optimisé pour avoir un haut indice de réfraction et une faible absorption optique pour l'ARC pour cellules solaires triple-jonction III-V/Ge. Ce matériau peut aussi servir de couche de passivation/encapsulation. Les simulations montrent que l'ARC double couche SiO2/LFSiN peut être très efficace pour réduire les pertes par réflexion dans la plage de longueurs d'onde de la sous-cellule limitante autant pour des cellules solaires triple-jonction limitées par la sous-cellule du haut que pour celles limitées par la sous-cellule du milieu. Nous démontrons aussi que la performance de la structure est robuste par rapport aux fluctuations des paramètres des couches PECVD (épaisseurs, indice de réfraction).

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

    The clinical presentation of Ludwig's angina consists in a severe expanding cellulitis causing swelling of the floor of the mouth, tongue and submandibular region, thus resulting in a possible obstruction of the airway and in a rapid progress in deep neck soft tissue infection and mediastinitis with potentially fatal consequences. Frequently, submandibular cellulitis develops from an acute infection spreading from the lower molar teeth. Mandibular fractures, traumatic laceration of the floor of the mouth, and peritonsillar abscesses are other concomitant clinical features. A case of Ludwig's angina associated with a large erupted odontoma and with a deeply impacted third molar displaced to the border of the mandible is described. The patient was affected by enlargement of submandibular space, marked face swelling causing an evident face deformity, tenderness and redness of the neck and limited movement of the neck and mouth. In the past, Ludwig's angina was frequently fatal, however aggressive surgical and medical therapy have significantly reduced the mortality rate. The reported case can be considered as important, not only because of the rarity of the odontoma eruption in the oral cavity, but mainly for the extent of the clinical manifestation of a lesion usually described in literature as asymptomatic.

    Richter syndrome (RS) is characterized by the development of a high-grade lymphoma in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Herein, we present the case of an 85-year-old woman with a 3-year history of stable asymptomatic CLL that developed a cutaneous RS. The patient presented with painless inflammation in the left leg and foot that was initially diagnosed as a cellulitis infection. She was treated accordingly with ceftriaxone and clindamycin. However, after completing the antibiotic regimen, not only did the inflammation persist, but also superimposed painless nodules gradually appeared on the left leg and foot over the course of four months. The histopathological examination of the nodules revealed a large B-cell cutaneous lymphoma. The patient underwent chemotherapy with CVP, followed by R-CHOP, resulting in a reduction of size of the nodules and remission of the inflammation. The patient died five months after the diagnosis owing to a bacterial pneumonia. We identified in previous reports a total of fifteen cases of cutaneous RS. Most cases presented with rapidly growing tumors or multiple erythematous nodules, similar to our case. This case of a cutaneous RS mimicking a cellulitis infection underlines the importance of a low threshold for performing biopsies of suspicious skin lesions in patients with CLL/SLL. PMID:27617524

    We characterized 144 Escherichia coli isolates from severe cellulitis lesions in broiler chickens from South Brazil. Analysis of susceptibility to 15 antimicrobials revealed frequencies of resistance of less than 30% for most antimicrobials except tetracycline (70%) and sulphonamides (60%). The genotyping of 34 virulence-associated genes revealed that all the isolates harbored virulence factors related to adhesion, iron acquisition and serum resistance, which are characteristic of the avian pathogenic E. coli (APEC) pathotype. ColV plasmid-associated genes (cvi/cva, iroN, iss, iucD, sitD, traT, tsh) were especially frequent among the isolates (from 66.6% to 89.6%). According to the Clermont method of ECOR phylogenetic typing, isolates belonged to group D (47.2%), to group A (27.8%), to group B2 (17.4%) and to group B1 (7.6%); the group B2 isolates contained the highest number of virulence-associated genes. Clonal relationship analysis using the ARDRA method revealed a similarity level of 57% or higher among isolates, but no endemic clone. The virulence of the isolates was confirmed in vivo in one-day-old chicks. Most isolates (72.9%) killed all infected chicks within 7 days, and 65 isolates (38.1%) killed most of them within 24 hours. In order to analyze differences in virulence among the APEC isolates, we created a pathogenicity score by combining the times of death with the clinical symptoms noted. By looking for significant associations between the presence of virulence-associated genes and the pathogenicity score, we found that the presence of genes for invasins ibeA and gimB and for group II capsule KpsMTII increased virulence, while the presence of pic decreased virulence. The fact that ibeA, gimB and KpsMTII are characteristic of neonatal meningitis E. coli (NMEC) suggests that genes of NMEC in APEC increase virulence of strains. PMID:23977279

    Introduction Oedematous lesions are a less common but more severe form of Mycobacterium ulcerans disease. Misdiagnosis as bacterial cellulitis can lead to delays in treatment. We report the first comprehensive descriptions of the clinical features and risk factors of patients with oedematous disease from the Bellarine Peninsula of south-eastern Victoria, Australia. Methods Data on all confirmed Mycobacterium ulcerans cases managed at Barwon Health, Victoria, were collected from 1/1/1998–31/12/2012. A multivariate logistic regression model was used to assess associations with oedematous forms of Mycobacterium ulcerans disease. Results Seventeen of 238 (7%) patients had oedematous Mycobacterium ulcerans lesions. Their median age was 70 years (IQR 17–82 years) and 71% were male. Twenty-one percent of lesions were WHO category one, 35% category two and 41% category three. 16 (94%) patients were initially diagnosed with cellulitis and received a median 14 days (IQR 9–17 days) of antibiotics and 65% required hospitalization prior to Mycobacterium ulcerans diagnosis. Fever was present in 50% and pain in 87% of patients. The WCC, neutrophil count and CRP were elevated in 54%, 62% and 75% of cases respectively. The median duration of antibiotic treatment was 84 days (IQR 67–96) and 94% of cases required surgical intervention. On multivariable analysis, there was an increased likelihood of a lesion being oedematous if on the hand (OR 85.62, 95% CI 13.69–535.70; P<0.001), elbow (OR 7.83, 95% CI 1.39–43.96; p<0.001) or ankle (OR 7.92, 95% CI 1.28–49.16; p<0.001), or if the patient had diabetes mellitus (OR 9.42, 95% CI 1.62–54.74; p = 0.02). Conclusions In an Australian population, oedematous Mycobacterium ulcerans lesions present with similar symptoms, signs and investigation results to, and are commonly mistakenly diagnosed for, bacterial limb cellulitis. There is an increased likelihood of oedematous lesions affecting the hand, elbow or ankle, and in

    To review and highlight the association of acne conglobata, hidradenitis suppurativa, and dissecting cellulitis of the scalp with inflammatory arthritic conditions, we report five illustrative patients with this association, and a review of the literature. All our patients were African-American males, and their skin disease present before the onset of arthritis. Both asymmetric peripheral arthritis and axial disease can occur. The arthritis is usually insidious and lacks association with rheumatoid factor and HLA-B27. Imaging of peripheral joints can reveal erosions, periosteal bone reaction and new bone formation. When the axial skeleton is involved, imaging can reveal sacroiliitis, syndesmophyte formation. NSAIDs, oral and intra-articular steroids, DMARDs and TNF alpha antagonists have all been used with success. Controlled trials with larger numbers of patients are needed to assess which treatment options are the most effective for this group of patients. PMID:23771559

    Purpose To identify significant clinical and radiological findings that distinguish rhino-orbito-cerebral mucormycosis (ROCM) from bacterial orbital cellulitis (BOC). Methods This study was retrospective, multicenter, case-control study that enrolled 34 cases; 14 cases were diagnosed with ROCM and 20 cases were diagnosed with BOC at three different tertiary hospitals between 2005 and 2013. The medical records of all 34 cases were reviewed. The initial clinical manifestations (eyelid swelling, ptosis, extraocular muscle [EOM] limitation, conjunctival injection, and chemosis) and computed tomography (CT) findings (sinus mucosal thickening, full opacification, and air-fluid level) of both diseases were compared. Results Patients with diabetes mellitus (DM) and hypertension (HTN) showed higher incidence rates of ROCM than BOC (DM: p < 0.001, HTN: p = 0.036). ROCM cases exhibited more frequent EOM limitation than cases with BOC (100.0% vs. 66.7%, p = 0.024) but less frequent eyelid swelling (35.7% vs. 90.0%, p = 0.002). However, the incidence rates of ptosis, conjunctival injection, and chemosis exhibited no differences between the diseases. Abnormal CT findings were observed in the sinuses of all patients with ROCM, whereas 12 patients with BOC had sinus abnormalities (100.0% vs. 60.0%, p = 0.011). Thickening of the sinus mucosa was more frequent in patients with ROCM than in those with BOC (92.9% vs. 45.0%, p = 0.009). No significant differences in full opacification or air-fluid level were detected between the groups. Conclusions The differential diagnosis of ROCM and BOC is difficult. Nevertheless, physicians should consider ROCM when a patient with suspected orbital cellulitis presents with EOM limitation without swollen eyelids or thickening of the sinus mucosa on a CT scan.

    Standard antibiotic treatment of infections has become more difficult and costly due to treatment failure associated with the rise in bacterial resistance. New antibiotics that can overcome such resistant pathogens have the potential for great clinical and economic impact. Linezolid is a new antibiotic that is effective in the treatment of both antibiotic-susceptible and antibiotic-resistant Gram-positive bacterial infections, including those resistant to other available antibiotics. This breadth of activity is unique in existing antibiotics for Gram-positive bacteria and serves as the rationale for exploring the hypothesis that linezolid is an appropriate choice when considering empirical treatment of cellulitis in complicated or compromised patients in the nosocomial setting. A decision-modelling approach was used to compare the predicted first-line treatment efficacy and direct medical costs of linezolid with standard treatment of cellulitis among hospitalized patients. For the purposes of this analysis, standard care is defined along two main pathways: (1) initiating care with intravenous (iv) flucloxacillin, switching to vancomycin if the pathogen is found to be resistant to flucloxacillin, or maintaining flucloxacillin if the pathogen is found susceptible, or when culture and sensitivity analysis is inconclusive; or (2) initiating care with vancomycin, switching to iv flucloxacillin if the pathogen is found susceptible to flucloxacillin, maintaining vancomycin if the infection is found resistant, or when culture and sensitivity are inconclusive. For those patients taking iv flucloxacillin, a switch to oral flucloxacillin was allowed when clinically appropriate. We hypothesized that the cost of care of initiating treatment with linezolid would be less than that for both vancomycin and flucloxacillin in resistance risk ranges typically encountered in UK hospitals. In addition, while the registration trials showed equivalence of linezolid with the comparators in

    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

The coding nucleobase-containing molecules in each cellule (named "lithocodon") partially shield each other; the remaining free space determines the stereochemical character of the filling side chain. Apatite-group minerals are considered as the most preferable for this type of coding (named "lithocoding"). A scheme of the cellule with certain stereometric parameters, providing for the isomeric selection of contacting molecules is proposed. We modelled the filling of cellules with molecules involved in direct coding, with the possibility of coding by their single combination for a group of stereochemically similar amino acids. The regular ordered arrangement of cellules enables the polymerization of amino acids and nucleobase-containing molecules in the same direction (named "lithotranslation") preventing the shift of coding. A table of the presumed "LithoCode" (possible and optimal lithocodon assignments for abiogenically synthesized α-amino acids involved in lithocoding and lithotranslation) is proposed. The magmatic nature of the mineral, abiogenic synthesis of organic molecules and polymerization events are considered within the framework of the proposed "volcanic scenario". PMID:27048216

    Dissecting cellulitis (DC) also referred to as to as perifolliculitis capitis abscedens et suffodiens (Hoffman) manifests with perifollicular pustules, nodules, abscesses and sinuses that evolve into scarring alopecia. In the U.S., it predominantly occurs in African American men between 20-40 years of age. DC also occurs in other races and women more rarely. DC has been reported worldwide. Older therapies reported effective include: low dose oral zinc, isotretinoin, minocycline, sulfa drugs, tetracycline, prednisone, intralesional triamcinolone, incision and drainage, dapsone, antiandrogens (in women), topical clindamycin, topical isotretinoin, X-ray epilation and ablation, ablative C02 lasers, hair removal lasers (800nm and 694nm), and surgical excision. Newer treatments reported include tumor necrosis factor blockers (TNFB), quinolones, macrolide antibiotics, rifampin, alitretinoin, metronidazole, and high dose zinc sulphate (135-220 mg TID). Isotretinoin seems to provide the best chance at remission, but the number of reports is small, dosing schedules variable, and the long term follow up beyond a year is negligible; treatment failures have been reported. TNFB can succeed when isotretinoin fails, either as monotherapy, or as a bridge to aggressive surgical treatment, but long term data is lacking. Non-medical therapies noted in the last decade include: the 1064 nm laser, ALA-PDT, and modern external beam radiation therapy. Studies that span more than 1 year are lacking. Newer pathologic hair findings include: pigmented casts, black dots, and "3D" yellow dots. Newer associations include: keratitis-ichthyosis-deafness syndrome, Crohn disease and pyoderma gangrenosum. Older associations include arthritis and keratitis. DC is likely a reaction pattern, as is shown by its varied therapeutic successes and failures. The etiology of DC remains enigmatic and DC is distinct from hidradenitis suppurativa, which is shown by their varied responses to therapies and their

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

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

    Precautionary recommendations conveyed to survivors of cancer by health-care practitioners to reduce the risk of breast cancer-related lymphoedema are indispensable aspects of clinical care, yet remain unsubstantiated by high-level scientific evidence. By reviewing the literature, we identified 31 original research articles that examined whether lifestyle-associated risk factors (air travel, ipsilateral arm blood pressure measurements, skin puncture, extreme temperatures, and skin infections-eg, cellulitis) increase the risk of breast cancer-related lymphoedema. Among the few studies that lend support to precautionary guidelines, most provide low-level (levels 3-5) or inconclusive evidence of an association between lymphoedema and these risk factors, and only four level 2 studies show a significant association. Skin infections and previous infection or inflammation on the ipsilateral arm were among the most clearly defined and well established risk factors for lymphoedema. The paucity of high-level evidence and the conflicting nature of the existing literature make it difficult to establish definitive predictive factors for breast cancer-related lymphoedema, which could be a considerable source of patient distress and anxiety. Along with further research into these risk factors, continued discussion regarding modification of the guidelines and adoption of a risk-adjusted approach is needed. PMID:27599144

    Gamma irradiation leads to an increased production of interleukin- (IL)-6 and IL-8 by human endothelial cells. In order to regulate the radio-induced production of these pro-inflammatory cytokines, we used the immunoregulatory cytokines IL-4 and IL-10. These agents were added either before or after a 10 Gy-irradiation. Our results show that it is possible to decrease the radio-induced production of IL-6 and IL-8 with the use of IL-4 and IL-10. Differences in the intensity of the response have been observed according to the time of treatment. The anti-inflammatory potential of both IL-4 and IL-10 was more pronounced when added after irradiation. Après irradiation gamma, des cellules endothéliales humaines ont une production accrue des interleukines (IL-) -6 et -8. Dans le but de réguler la production de ces cytokines pro-inflammatoires, nous avons utilisé des cytokines dites anti-inflammatoires, l'IL-4 et l'IL-10. Ces agents ont été ajoutés soit avant soit après une irradiation de 10Gy. Nos résultats montrent qu'il est possible de diminuer les productions radio-induites d'IL-6 et d'IL-8 par l'IL-4 et l'IL-10. Des différences dans l'intensité de la réponse ont toutefois été observées selon que l'IL-4 ou l'IL-10 ont été ajoutées avant ou après irradiation; leur efficacité anti-inflammatoire étant plus marquée lorsque les cytokines sont ajoutées après l'irradiation.

    In spite of the contribution of the new techniques of radiology and the use of new antibiotics, the diagnosis of perinephric abscess remains difficult and late and is at the origin of high morbidity and mortality. 75 cases of perinephric abscess collected during 15 years are reviewed. We studied the etiopathogenic, diagnostic, bacteriologic and therapeutic characteristics of this affection. Urinary signs are found in 26.7% of patients, diabetes in 17% and extra urinary origin is found in 11% of patients. Diagnostic delay is over one month in 75% of patients. Ultrasonography is carried out in 55 patients showing evocative images of perinephric abscess in 96% of cases. Computed tomography seems more performant than ultrasonography. Gram negative bacillus and staphylococcus are the germs which are the most frequently found. Surgical drainage associated to antibiotherapy is realized in all patients with collected perinephric abscess (73 cases). Evolution is often favourable in spite of the expanse of the abscedation. Literature data about pathogenesis, bacteriology, diagnosis and treatment of this affection are discussed. PMID:7719371

    We are sharing a case of orbital cysticercosis,which presented to us initially with simple ptosis and later on with upper lid inflammation and restricted ocular motility in upgaze. Human cysticercosis, a parasitic infection caused by Cysticercus cellulosae, the larval form of the cestode, Taenia solium, is a benign infection of the subcutaneous tissues, inter-muscular fascia, muscles and other organs. Though it exists worldwide, it is more prevalent in the developing countries of Latin America, Asia and Africa, especially in areas where under-cooked pork is consumed regularly (Pushker et al, 2001). However, 5 year study of 33 cases of Ocular/Adnexal cysticercosis showed seventy percent of patients were of low socioeconomic group and 70% were strictly vegetarians (Atul et al, 1995). The clinical manifestation of orbital cysticercosis is entirely different from neuro-cysticercosis or cysticercosis of other parts of body. Diagnosis of cysticercosis is mainly based on highly specific radiological signs and history of exposure in endemic areas. PMID:27363971

    Fadlallah, Hicham

    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.

    Perianal streptococcal dermatitis is an uncommon superficial cutaneous infection of the perianal area almost exclusively described in children. Perianal streptococcal dermatitis is caused by group A beta-hemolytic streptococci and occurs mainly in children between six months and ten years of age. Prior therapy with topical antifungal agents, topical corticosteroids, and oral preparations for pinworms either fails to improve or worsens patient's symptoms. Early antibiotic therapy causes a dramatic and rapid improvement of symptoms. Treatment protocol consists of amoxicillin 40 mg/kg/day, divided into three doses, and/or topical application of mupirocin 2% ointment three times per day for ten days. We describe a four-year-old boy with perianal streptococcal dermatitis who was brought to our clinic with plaque type psoriasis.

    A 51-year-old man presented to a community based emergency department with bilateral lower extremity swelling that began four days prior and that had evolved into recent blister formation on the left lower extremity. Medical history was significant only for hypertension and a recent self-described episode of "food poisoning" five days earlier characterized by diarrhea, nausea, and vomiting that quickly resolved. Physical exam revealed marked bilateral lower extremity edema and an ecchymotic rash below the knee. In addition to the rash, there were large flaccid bullae on the left leg, mostly intact but some notable for draining of scanty serosanguinous fluid. The patient was tachycardic with a rate of 114 bpm and initial labs showed thrombocytopenia (platelets 56 x 103/uL [140-440 x 103/uL]), hypoglycemia (15mg/dl [70-105mg/dl]), an elevated creatinine (2.7mg/dL [0.7- 1.25mg/dL]), and aspartate aminotransferase (AST 156U/L [5- 34U/L]). Two sets of blood cultures were drawn, broad spectrum antibiotics including doxycycline were empirically initiated and then he was subsequently transported to a tertiary care hospital for escalation of care. Within hours of presentation to the tertiary care facility, the rash appeared progressively hemorrhagic and bullous, lactic acidosis and coagulopathy developed and hemodynamic instability and septic shock necessitated endotracheal intubation and vasopressors. He was taken to the operating room for skin debridement but was emergently converted to bilateral above the knee lower extremity amputations due to the extent of the soft tissue necrosis. The patient remained intubated and in critical condition following surgery and the ecchymotic rash reappeared at the amputation sites. A newly developed ecchymotic rash with bullae formation was noted on the right upper extremity forearm. At that time, the clinicians were notified that four out of four blood culture bottles from admission were rapidly growing a microorganism. The family elected for withdrawal of care, and the patient died approximately 72 hours following presentation. A full and unrestricted autopsy was authorized by the Coroner's Office. PMID:27389382

    Amphiphilic block copolymers can self-assemble in water into various stable morphologies which resemble key cell structures, notably filaments and membranes. Filamentous 'worms' of copolymer, microns-long, are briefly introduced, and related dynamics of copolymer vesicle 'polymersomes' are reviewed. Fluorescence visualization of single worms stretched under flow demonstrates their stability as well as a means to control conformation. Polymersome membranes have been more thoroughly studied, especially copolymer molecular weight effects. We summarize results suggestive of a transition from Rouse-like behavior to entangled chains. Viewed together, the results ask the question: what physics are needed next to mimic cell activities such as crawling? To cite this article: P. Dalhaimer et al., C. R. Physique 4 (2003).

    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 π-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.

  9. MODIFICATIONS ULTRASTRUCTURALES DES CELLULES SÉCRÉTRICES DE LA GLANDE PROTHORACIQUE DE VERS À SOIE AU COURS DES DEUX DERNIERS ÂGES LARVAIRES

    Ultrastructural study of the prothoracic glands of silkworms (Antheraea pernyi and Bombyx mori) at the last two larval stages has shown that the essential modifications which take place during each intermolt affect the chondriome of secretory cells. A description is given of the differentiation of macromitochondria from typical mitochondria by a general swelling, a clearing of the matrix, and the formation of a complex tubular network. The hypothesis of fixation or anaesthesia artifacts has been dismissed because of the persistence of these transformations after different fixations and because of the existence of numerous intermediary stages between these two types of chondriosomes which imply the progressiveness of differentiation. The cytochemical demonstration of mitochondrial DNA fibers suggests that the genetic information, probably present in this type of nucleic acid, controls the differentiation and the specific metabolic activity of these organelles. The frequent relationships observed in Antheraea between the tubules of agranular reticulum and the macromitochondria which are reminiscent of the vacuoles-mitochondria associations of the adrenal cortex, may be related to the transfer of cholesterol and other precursors of steroidogenesis. In the last stages, the macromitochondria become transformed into vacuoles by a disappearance of the tubular network. The correlation revealed between mitochondrial transformations and the cyclical release of ecdysone (65) leads to the conclusion that a prominent fraction of chondriosomes is involved, in relation to the agranular reticulum, in the elaboration of steroid hormones such as ecdysone.

    2001-10-01

    Common skin and soft tissue infections in nursing home patients include herpes zoster, cellulitis, pressure ulcer infections, and scables. Treatment of shingles with an oral antiviral should be started within 24 hours of symptom onset. Dissemination and bacterial superinfection require antibiotic therapy. Use of corticosteroids to prevent post-herpetic neuralgia remains controversial. Cellulitis is most often caused by Staphylococcus aureus and beta-hemolytic streptococci (groups A and B). Therapy for cellulitis is empiric; gram-negative bacilli should be covered in diabetic patients. Most pressure ulcers never become infected; for those that do, empiric therapy should cover S aureus, gram-negative bacilli, and anaerobes. Topical treatment of scables with 5% permethrin cream or 1% lindane lotion is recommended.

    Introduction: Superficial facial space infections represent a significant amount of the dental problems that present to hospital. Determining whether an odontogenic swelling is a cellulitis or abscess is difficult, but important as both may require different treatments. The use of an ultrasound may aid in differentiating cellulitis and abscess. This study was done to compare the accuracy of clinical examination alone versus ultrasonography (USG) in the diagnosis of cellulitis and abscess in symptomatic patients with a diagnosis of superficial facial space infection. Materials and Methods: Twenty patients (1870 years) diagnosed as superficial facial space infections by clinical and radiographic examinations were included in the study and patients with significant medical conditions were excluded. The provisional clinical diagnosis was made after a thorough history was taken and clinical examination was performed to determine if the swelling was a cellulitis or abscess. Swelling was then evaluated using the ultrasonic transducer which was placed over the swelling to aid the diagnosis which was again recorded. An incision and drainage procedure was performed after the administration of local anesthesia. The success of the ultrasound intervention versus clinical examination was based on whether frank exudation was detected during incision and drainage of such swellings. Results: The statistical analysis found that USG is a valuable diagnostic aid for detection of abscess or cellulitis in head and neck facial space infections. Interpretation and Conclusion: The findings of this prospective analysis indicate that there was statistical difference between clinical examination alone and USG in making the correct diagnosis. The sensitivity, specificity, positive predictive, negative predictive, and accuracy were not similar for all methods tested. From the results of this study, ultrasound is recommended as an adjunct to clinical examination in differentiating between

  2. Periorbital Dirofilariasis: A Rare Case from Western India

    PubMed Central

    2016-01-01

    Dirofilariasis is a zoonotic disease caused commonly by Dirofilaria repens and Dirofilaria immitus. The definitive hosts are domestic dogs and cats. Human beings are accidental dead end hosts, and acquire infestation through mosquito bites. So far, very few cases have been reported from western India. We report a case of a 27-year-old male who presented with preseptal cellulitis right eye and a firm mass in the lower lid. Histopathological examination after surgical excision of the mass revealed a diagnosis of dirofilariasis. Although rare in Western India a diagnosis of dirofilariasis should be considered in cases of preseptal cellulitis associated with a periorbital mass. PMID:27134918

  15. Caracterisation thermique de modules de refroidissement pour la photovoltaique concentree

    NASA Astrophysics Data System (ADS)

    Collin, Louis-Michel

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

    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.

    2015-01-01

    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.

    Epistaxis is a very common emergency in otorhinolaryngology. Anterior ethmoidal artery ligation using an external approach is one of the surgical options in posterior epistaxis. We present, to the best of our knowledge, the first reported case of an intracerebral abscess after epistaxis treatment with ligation of the anterior ethmoidal artery using an endoscopic-assisted external approach in a 56-year-old patient. The patient presented 4 days postoperatively with an orbital cellulitis. A CT was performed and a frontobasal hypodensity was found. An additional MR tomography the next day showed a lesion suspicious for an intracerebral abscess. Despite intravenous antibiotic therapy, the lesion increased and was successfully treated by the neurosurgeons, with abscess resection over a craniotomy and frontobasal repair using a pedicled periosteal flap. Surgeons have to be aware of this rare but possibly lethal severe complication and should consider early imaging studies, especially if a periorbital cellulitis appears.

    2016-06-15

    Eye problems constitute 2% to 3% of all primary care and emergency department visits. Common eye conditions that can cause eye pain are conjunctivitis, corneal abrasion, and hordeolum, and some of the most serious eye conditions include acute angle-closure glaucoma, orbital cellulitis, and herpetic keratitis. The history should focus on vision changes, foreign body sensation, photophobia, and associated symptoms, such as headache. The physical examination includes an assessment of visual acuity and systematic evaluation of the conjunctiva, eyelids, sclera, cornea, pupil, anterior chamber, and anterior uvea. Further examination with fluorescein staining and tonometry is often necessary. Because eye pain can be the first sign of an ophthalmologic emergency, the physician should determine if referral is warranted. Specific conditions that require ophthalmology consultation include acute angle-closure glaucoma, optic neuritis, orbital cellulitis, scleritis, anterior uveitis, and infectious keratitis.

They consist microscopically of all the tissue types found in a developed tooth. We present a case of a large sequestrating complex odontoma resulting in facial asymmetry, cellulitis, pain and partial loss of function. This case has significance, as odontomas of this large size have rarely been reported.

    In brief: An ingrown toenail is one of the most common diseases of the nail. Initial treatment includes trimming away the ingrown area and soaking the foot in Epsom salt, or a combination of Epsom salt and pHisoHex or Betadine. If inflammation, localized cellulitis, and pain do not resolve rapidly, chemocautery with phenol or a surgical partial matricectomy can be carried out. PMID:27409375

    A 69-year-old man presented with sudden onset of pain with acute tense swelling of his left leg. Initially he was treated empirically with antibiotics for cellulitis while the possibility of deep vein thrombosis was ruled out. His symptoms gradually worsened with progressive distal neurological deficit and increasing pain. Further investigations suggested that he had a ruptured Baker's cyst in the calf with development of compartment syndrome.

    67 patients were investigated. From these patients, 35 had been persistent form of Allergic Rhinitis and 32 - intermittent form of pathology. It has been established, that in patients with Allergic Rhinitis the treatment with intranasal electrophoresis of vanadium strenghthens T-cellulal immunity, has a desensitization action, increases non-specific resistance of the organism and has a normalizing influence on the indices of humoral immunity. The above shown positive shift were more pronounced in patients with intermittent form of Allergic Rhinitis.

    Agrobacterium tumefaciens (radiobacter) is usually a plant pathogen, but is isolated occasionally from human clinical specimens, frequently along with other bacteria. Agrobacterium tumefaciens (radiobacter) has been isolated from blood, central intravenous catheters, peritoneal fluid, urine, and cellulitis aspirates, often in immunocompromised individuals. This report details the isolation of A. tumefaciens (radiobacter) from the blood of a pregnant woman, as well as from the blood of her stillborn, premature fetus. It is, to our knowledge, the first report of such an occurrence.

    Il cancro del rene rappresenta la 13a forma di tumore a livello mondiale e risulta incrementata, dal punto di vista epidemiologico, di circa il 2% annuo nelle ultime due decadi. Studi recenti hanno mostrato un numero complessivo di 65,150 nuovi casi di cancro renale diagnosticato nei paesi occidentali e circa 13.680 morti. Il carcinoma a cellule renali rappresenta approssimativamente il 90% di tutte le forme di cancro renale e presenta un tasso di mortalità di circa 4 soggetti ogni 100000 abitanti per anno. Il carcinoma a cellule renali ha, spesso, un particolare corteo sintomatologico caratterizzato da dolore addominale, masse addominali ed ematuria. Caratteristico è il fatto che circa il 25-30% dei pazienti, all’atto della diagnosi, presentano già metastasti a distanza; un ulteriore 30-50%, inoltre, svilupperanno metastasi nel corso della malattia, anche dopo molti anni dall’operazione chirurgica di nefrectomia radicale. Il Cancro del Rene a Cellule Chiare metastatizza in genere per via linfatica, ematogena, transperitoneale o per invasione diretta, ed i siti di metastasi più comuni sono il polmone ed i linfonodi, seguiti dalle ossa e dal fegato. Tra tutte le possibili localizzazioni ai segmenti addominali, il duodeno rappresenta la sede meno colpita: quando coinvolta, viene, in genere, invasa la regione periampollare ed il bulbo del duodeno. Tali localizzazioni danno segno di sè, spesso tardivamente, con sanguinamenti (ematemesi) o ostruzioni del tratto gastrointestinale superiore (vomito). Il nostro caso clinico descrive un carcinoma a cellule renali che si presentava, dopo soli 5 mesi dalla nefrectomia radicale destra, con sanguinamento del tratto gastrointestinale superiore e metastasi a carico del duodeno, e che è stato trattato chirurgicamente con duodenocefalopancreasectomia. L’intervento chirurgico, noto per essere altamente demolitivo ed associato ad elevata morbilità, applicato a recidiva precoce di cancro, ha garantito un ottimo risultato

    Introduction: Orbital cellulits following cataract surgery is extremely rare. We describe a case of orbital and facial cellulitis that occurred after routine cataract operation with peribulbar anaesthesia. There were no preoperative systemic or ocular risk factors for postoperative infection. Case description: An 89-year-old man presented to eye casualty, the day after he underwent an uneventful phacoemulsification and posterior chamber lens implantation in the left eye under peribulabr anaesthesia, with soreness, swelling and reduced visual acuity (6/18) in the operated eye. On initial presentation periorbital swelling was noted, the eye was minimally tender, intraocular pressure was raised at 28 mHg and fundoscopy was limited due to a hazy cornea. The patient was discharged on topical medication with a diagnosis of allergic reaction to postoperative drops. The following day, the patient re-presented with worsening orbital swelling involving the left cheek. Ocular findings remained unchanged. CT scan revealed left orbit soft tissue swelling and a locule of air medial to the medial rectus. There were no signs of sinus infection or periosteal inflammation. A diagnosis of left orbital and facial cellulitis was made and the patient was treated with intravenous antibiotics. Discussion: Our patient did not have any predisposing risk factors, therefore most likely cause of cellulitis is surgical trauma during administration of the peribulbar block. This case illustrates the need for adequate skin preparation before the administration of peribulbar anaesthesia and minimal tissue trauma during the procedure.

    We report a rare case of sling shot injury that presented with a gunshot-like wound with preseptal cellulitis, in a toddler. An 11-month-old Malay child presented with a gunshot-like wound over the forehead following sling shot injury. On examination, he had a deep circular laceration wound over the forehead, measuring 2.0 cm in diameter, with minimal bleeding. There was no obvious foreign body seen inside the wound and no palpable foreign body surrounding the wound. The gunshot-like wound was associated with left preseptal cellulitis. A skull X-ray showed a white opaque foreign body in the left frontal bone. Computed tomography (CT) scan of orbit and brain revealed a left comminuted fracture of the left orbital roof, and left frontal brain contusion with prelesional edema. Wound exploration was performed and revealed a 0.5 cm unshattered marble embedded in the left frontal bone. The marble and bone fragments were removed. The left preseptal cellulitis responded well to intravenous antibiotic and topical antibiotic. PMID:25709507

    Clostridial dermatitis (CD) is a production disease of commercial turkeys that is characterized by sudden mortality in market-aged male birds and by lesions that include fluid and air bubbles under the skin of the thigh, breast, and tail area. We have developed a model for CD using dexamethasone (Dex) injection that suggests this disease may be related to stressors during the last stages of turkey production. Male turkeys were provided with control feed and water or with feed supplemented with a commercial yeast extract (YE) product, water supplemented with vitamin D (VD), or the combination. At 6, 11, and 15 wk of age birds were treated with three intramuscular injections of Dex over a 5-day period. Both YE and VD, but not the combination, decreased early mortality. At week 7 mortality was increased by VD, and cellulitis lesions were seen in 7/8 mortalities. Mortality at week 12 was decreased by both YE and the combination of YE and VD, and cellulitis lesions were seen in 8/17 mortalities. There were no significant differences in mortality at week 16. Total mortality was 66 birds, and 23 of these had cellulitis lesions (38%). There were no YE-treated birds with CD lesions; however, 67% of VD-treated birds had CD lesions. This study suggests that feed supplementation with YE may improve the ability of turkeys to withstand the stressors during late production and provide protection against the development of CD; however, high levels of VD supplementation may be detrimental.

    Cervical adenitis >1.5cm in diameter is the less frequently observed criteria in patients with Kawasaki disease and it is usually found in association with other symptoms during the acute phase. Moreover, the finding of fever and lymphadenitis with intense local signs of inflammation and phlegmon is rarely seen as the initial manifestation of Kawasaki disease. We report the case of a 7-year-old boy who had cervical lymphadenitis with adjacent cellulitis and phlegmon mimicking bacterial adenitis as the first presentation of Kawasaki disease. The patient had fever, cervical lymphadenitis with adjacent cellulitis, and severe headache. Cefadroxil was prescribed based on the clinical diagnosis of bacterial adenitis. Because he remained febrile and phlogistic signs worsened, after 1 day of hospitalization, antibiotics were administrated intravenously (ceftriaxone and oxacillin). The computed tomography of the neck showed primary infectious/inflammatory process. On the fourth day, the patient had dry and scaly lips, and treatment with oxacillin was replaced by clindamycin because the patient was still febrile. On the ninth day, he presented non-exudative bilateral conjunctival injection. On the tenth day of febrile disease, a rash appeared on his trunk, hands and feet. Patient’s symptoms resolved after intravenous administration of immunoglobulin (2g/kg/dose), and he was discharged 2 days later. On the 14th day, the patient had lamellar desquamation of fingers. Kawasaki disease should be considered as a differential diagnosis in children with febrile cervical lymphadenitis unresponsive to empiric antibiotics even if they have adjacent cellulitis and phlegmon.

    Le ulcere cutanee croniche colpiscono circa l’1% della popolazione adulta e il 3.6% della popolazione con più di sessantacinque anni di età. Per quanto riguarda l’impegno finanziario per la terapia delle ulcere cutanee, questo è pari a sette miliardi di euro annui a livello mondiale. Le cellule staminali mesenchimali prelevate da lipoaspirato (ASCs) rappresentano una delle frontiere più promettenti della medicina rigenerativa. Diversi studi hanno, infatti, dimostrato l’efficacia terapeutica di questa popolazione di cellule staminali nel trattamento delle ulcere cutanee croniche. Le ASCs hanno caratteristiche morfologiche e funzionali paragonabili alle cellule staminali del midollo osseo (BMSCs), tuttavia se ne differenziano per la maggiore facilità di prelievo e isolamento, e per il loro più cospicuo numero. È, infatti, sufficiente eseguire una liposuzione tradizionale e in seguito utilizzare metodiche d’isolamento appropriate per ottenere un pellet di ASCs pronte per essere innestate nel fondo e nel margine dell’ulcera cutanea, al fine di promuoverne la guarigione. Diversi sono i protocolli d’isolamento; i più diffusi prevedono complicati e lunghi procedimenti, caratterizzati dal susseguirsi di differenti prodotti sia chimici sia biologici, i quali sono non solo costosi ma anche potenzialmente pericolosi. Il nostro protocollo d’isolamento richiede solo 15’ e prevede che il lipoaspirato sia prima sistemato in uno shaker cellulare e successivamente in una centrifuga così da ottenere le ASCs richieste per la terapia. L’uso delle ASCs si è rivelato una risorsa preziosa per la terapia delle ulcere cutanee croniche, accelerando significativamente il processo di guarigione e la rigenerazione dei tessuti; con protocolli d’isolamento efficaci e semplificati, il loro utilizzo routinario risulta essere facilitato.

    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

    Streptococcus dysgalactiae subsp. dysgalactiae (SDSD) are considered exclusive animal pathogens; however, a putative zoonotic upper limb cellulitis, a prosthetic joint infection and an infective endocarditis were described in humans. To unravel if bovine SDSD isolates are able to infect human cells, the adherence and internalization to human primary keratinocytes of two bovine SDSD strains isolated from milk collected from udder were analyzed. Bacterial adhesion assays and confocal microscopy indicate a high adherence and internalization of SDSD isolates to human cells, suggesting for the first time the ability of bovine isolates to infect human cells.

    A 32-year-old female who underwent scleral buckle removal presented 5 weeks postoperatively with a red, fluctuant subconjunctival mass. CT scan identified an irregularly bordered, hypoattenuated lesion next to the globe with the density of air. Ophthalmic plastic and reconstructive surgeons were consulted to evaluate orbital cellulitis with intraorbital gas, at which point it was deemed that the hypoattenuated mass was likely a retained sponge element based on its radiological features. Additional surgical exploration identified the retained silicone sponge. This clinical photographic-radiological correlation of retained silicone sponges presenting as orbital inflammation reminds surgeons to meticulously explant buckle material. PMID:27413562

    The role of computerized blood flow analysis in routine bone scanning is reviewed. Cases illustrating the technique include proven diagnoses of toxic synovitis, Legg-Perthes disease, arthritis, avascular necrosis of the hip, fractures, benign and malignant tumors, Paget's disease, cellulitis, osteomyelitis, and shin splints. Several examples also show the use of the technique in monitoring treatment. The use of quantitative data from the blood flow, bone uptake phase, and static images suggests specific diagnostic patterns for each of the diseases presented in this atlas. Thus, this technique enables increased accuracy in the interpretation of the radionuclide bone scan.

    Infections of the vulva can present a complex differential to the gynecologist, ranging from superficial skin infections to lifethreatening necrotizing fasciitis. Recognition and timely treatment remain universal to skin and soft-tissue infections as the subcutaneous anatomy of the vulva can facilitate rapid spread to other tissues with significant morbidity and mortality. Employing a multidisciplinary team approach to care for vulvar cellulitis and abscess can guide treatment from antibiotic therapies to more aggressive surgical debridement. In this report, we describe a case of vulvar abscess caused by Methicillin-resistant staphylococcus aureus (MRSA) in a postmenopausal woman with underlying diseases of bronchiectasis and atelectasis.

The condition is usually associated with end-stage renal disease and has a poor prognosis. We present a 76-year-old man on hemodialysis who developed small, painful purpura on the thigh. The purpura rapidly spread to his back and hip and became ulcerated. Histological examination of a skin biopsy revealed arterial calcification in the subcutaneous adipose tissue. We therefore diagnosed calciphylaxis and administered intravenous antibiotics and debrided the necrotic soft tissue. However, the lesions did not heal and the patient died from sepsis related to cellulitis. PMID:21063168

Others dermatoses are environmental diseases such as sunburns, arthropod-related reactions and superficial injuries. The most common tropical skin disease is hookworm-related cutaneous larva migrans but treating physicians may also face patients with localized cutaneous leishmaniasis, tungiasis, or myiasis. Also some systemic infections can be associated with skin manifestations. The most useful treatments in this setting are oral antihistamines, topical steroids, antibiotics effective against bacterial skin infection, booster for tetanus immunization, and rabies vaccination in case of animal exposure.

    Pansclerotic morphea is a rare subtype of localised scleroderma. Very few cases have been reported in the literature. This case discusses a young man with a 15-year history of pansclerotic morphea, illustrating the clinical course and complications of this disease. Notably, recurrent squamous cell carcinomas with several high-risk features and frequent cellulitis were the basis of many admissions. As often seen with this disease, autoimmune markers were negative. However, marked eosinophilia was noted late in the course. Furthermore, this disease is quite resistant to treatment. Immunosuppressive therapy thus far has perhaps slowed the progression, although not cured the disease in this patient. PMID:25312894

    Recent advances in nuclear imaging have improved the noninvasive evaluation of patients with nonmalignant bone disorders. 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. Stress fractures in joggers may be detected by radionuclide bone scintigraphy before radiographs become abnormal. These nuclear imaging procedures can be done in most hospitals.

In all patients, fever and systemic erythema without hemodynamic disturbance occurred following cellulitis of the lower limbs. At the site of infection, TSST-1 producing Methicillin-susceptible Staphylococcus aureus was detected. They defervesced and erythema resolved in response to administration of an antimicrobial drug, thereby avoiding severe illness. These patients did not meet the criteria for a clinical diagnosis of toxic shock syndrome. Measurement of T-cell receptor Vβ2-positive T cells in the peripheral blood early after onset of symptoms was useful for diagnosis.

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

    Soft tissue infections and angioedema from insect bites and stings may be difficult to differentiate by inspection. We present sonographic findings of 4 cases of soft tissue swelling from insect bites and stings suggestive of angioedema. Sonographic features of soft tissue angioedema consist of thickened subcutaneous tissue layers with multiple linear, horizontal, striated, and hypoechoic lines following the tissue planes between soft tissue layers. In addition to the history and physical examination, sonographic findings may assist in differentiating between local allergic reactions and cellulitis in patients with insect bites and stings. Further study is warranted for clinical application.

    Magnetic resonance imaging (MRI) is the modality of choice to identify intracranial or perineural spread from a head and neck primary tumor. Perineural spread is a form of metastatic disease in which primary tumors spread along neural pathways. Orbital cellulitis is a sight-threatening, and potentially life-threatening condition. Urgent imaging is performed to assess the anatomic extent of disease, including postseptal, cavernous sinus, and intracranial involvement, and identify orbital abscesses that require exploration and drainage. MRI is useful in the evaluation of the brachial plexus.

    Lupus vulgaris (LV) is the most common morphological variant of cutaneous tuberculosis. However, the occurrence of bizarre clinical presentations over atypical sites often leads to misdiagnosis and inappropriate treatment causing significant morbidity. This report seeks to highlight two unusual cases of lupus vulgaris occurring on the face of immunocompetent women and remarkably mimicking periorbital cellulitis and basal cell carcinoma, respectively. The diagnosis was confirmed by histopathology, an enzyme-linked immunosorbent assay (ELISA) test for Mycobacterium tuberculosis and polymerase chain reaction (PCR). With four-drug antitubercular therapy, both patients had a dramatic response.

    A 36-year-old man with type 1 diabetes developed skin inflammation at the site of subcutaneous insulin injection after 10 years of basal bolus subcutaneous insulin therapy. This inflammation led to poor insulin absorption, poorly controlled blood glucose and subsequently to ketoacidosis. The problem persisted despite a trial of continuous subcutaneous insulin infusion. The patient went on to be treated with continuous intraperitoneal insulin infusion. Three months after the procedure, he was achieving good glucose control and was able to resume his normal life, with the only complication being an episode of cellulitis surrounding the port site.

    Acquired lymphangiectasis is a dilatation of lymphatic vessels that can result as a complication of surgical intervention and radiation therapy for malignancy. Acquired lymphangiectasis shares clinical and histologic features with the congenital lesion, lymphangioma circumscriptum. Diagnosis and treatment of these vesiculo-bullous lesions is important because they may be associated with pain, chronic drainage, and cellulitis. We describe two patients who had these lesions after treatment for cancer and review the pertinent literature. Although a number of treatment options are available, we have found CO2 laser ablation particularly effective. PMID:9932832

    1982-05-01

    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.

    In December 1988 an indigenous case of cutaneous anthrax was identified in Texas. The patient, a 63-year-old male Hispanic from southwest Texas, was a sheep shearer and had a recent history of dissecting sheep that had died suddenly. He experienced an illness characterized by left arm pain and edema. A necrotic lesion developed on his left forearm, with cellulitis and lymphadenopathy. After treatment with oral and intravenous penicillins, the patient fully recovered. Western blot testing revealed a fourfold or greater rise in antibody titer to Bacillus anthracis protective antigen and lethal factor. This represents the first case of indigenous anthrax in Texas in more than 20 years. PMID:8420007

    The neutrophil-associated and infiltrative scarring alopecias are reviewed including folliculitis decalvans, tufted folliculitis, dissecting cellulitis of the scalp, acne keloidalis and follicular degeneration syndrome. The management of acquired scalp alopecia is also reviewed including newer, promising therapies. More specific agents targeting components of the androgen system will make the treatment of androgenetic alopecia more rewarding. Similarly new immunomodulatory therapies show great promise for the lymphocyte-associated alopecias and include a new generation of macrolide immunosuppressives (tacrolimus, SDZ ASM 981, and SDZ 281-240), some of which appear to have good transcutaneous absorption.

    The use of ultrasound in osteomyelitis has been studied in 25 patients clinically suspected of osteomyelitis. A sonographic diagnosis of osteomyelitis was made if fluid was present in direct contact with the bone, without intervening soft tissues. This was thought to represent an inflammatory exudate dissecting in a subperiosteal and/or extraperiosteal location. Ultrasonographically 15 patients were found to have osteomyelitis, proved either by surgical drainage or needle aspiration. Seven patients had soft-tissue abscesses, one had cellulitis and two patients had no abnormality. PMID:1393388

    We are seeing an increased number of complications in intravenous drug abusers who resort to injecting the groin for vascular access (the "groin hit"). Vascular complications include venous thrombosis, arteriovenous fistula, mycotic aneurysm, ruptured pseudoaneurysm, and dissecting hematoma. Soft tissue complications include cellulitis and abscess. The latter may dissect into the extraperitoneal space. Skeletal complications include osteomyelitis and septic arthritis. This paper illustrates the radiographic spectrum of these complications. An algorithm will illustrate the radiographic evaluation of a groin mass in a drug addict. PMID:2727357

    2010-09-01

    Infections due to methicillin-resistant Staphylococcus aureus (MRSA) have become more prevalent, in part because of the emergence and spread of community-acquired MRSA. This trend is particularly concerning because of the significant rates of morbidity and mortality associated with MRSA infections, and because MRSA strains are often resistant to many classes of antibiotics. Reports of infections of the head and neck, including wound infections, cellulitis, sinusitis, otitis media, and otitis externa, are well documented. However, to our knowledge, there have been no reports of bacterial laryngitis due to MRSA. We report the first published case of bacterial laryngitis caused by MRSA.

    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

    Infections of the vulva can present a complex differential to the gynecologist, ranging from superficial skin infections to lifethreatening necrotizing fasciitis. Recognition and timely treatment remain universal to skin and soft-tissue infections as the subcutaneous anatomy of the vulva can facilitate rapid spread to other tissues with significant morbidity and mortality. Employing a multidisciplinary team approach to care for vulvar cellulitis and abscess can guide treatment from antibiotic therapies to more aggressive surgical debridement. In this report, we describe a case of vulvar abscess caused by Methicillin-resistant staphylococcus aureus (MRSA) in a postmenopausal woman with underlying diseases of bronchiectasis and atelectasis.

    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

    Submasseteric space infections are rare at any age but particularly so in primary school children. The origin of the infection is usually odontogenic, from pericoronitis in a third molar. Submasseteric inflammation is a deep facial space inflammation, often progressing to mature abscess, and usually misdiagnosed as staphylococcal or streptococcal lymphadenitis or pyogenic parotitis. The hallmark of a masticatory space infection is trismus. The cardinal signs of this infection include a firm mass in the body of the masseter muscle with overlying cellulitis with trismus.

    A young girl developed an intracranial abscess and necrotizing cellulitis following penetrating injury from a lawn dart. Initial identification of a gram-positive rod growing aerobically from clinical specimens was as a Bacillus organism, but the observation that the isolate grew poorly in subcultures for susceptibility testing but quite well under standard anaerobic culture techniques led to the identification of the organism as an aerotolerant Clostridium tertium. Early management of penetrating head trauma should include cranial imaging studies to detect fractures and intracranial pathology. Clinical microbiologists and clinicians should be aware of the phenomenon of aerotolerance in anaerobic bacteria to avoid errors in choice of antibiotic therapy. Images PMID:2229397

    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.

    Antibiotics have a significant role in dermatology, treating a wide range of diseases, including acne, rosacea, inflammatory skin conditions and skin structure infections, such as cellulitis, folliculitis, carbuncles, and furuncles. Because of their consistent use, utility, and availability, antibiotics are susceptible to overuse within the medical practice, and, specific to this discussion, in the dermatologic setting. The issue of continuously increasing risk of antibiotic resistance remains an important concern to the dermatologist. The scope of this review will be to provide an overview of the common antibiotics used in the dermatologic setting with an emphasis on identifying areas of overuse, reported bacterial resistance, and discussion of clinical management aimed at decreasing antibiotic resistance.

    Hereditary angioedema is an autosomal dominant and life-threatening disorder characterized by recurrent episodes of non-pitting edema affecting the skin, respiratory system and digestive tracts and caused by a congenital deficiency or function defect of the C1 esterase inhibitor. Preseptal cellulitis is defined as an infection of the tissues of the anterior orbital septum. It is generally caused by complications from an upper respiratory tract infection, dacryocystitis, dermal infection, and, rarely, sinusitis. The disease presents with orbital pain, edema on the eyelids, erythema, and fever. In this case, a child with hereditary angioedema type 2 who presented as mimicking a complication of acute sinusitis is discussed.

    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.

CT scan identified an irregularly bordered, hypoattenuated lesion next to the globe with the density of air. Ophthalmic plastic and reconstructive surgeons were consulted to evaluate orbital cellulitis with intraorbital gas, at which point it was deemed that the hypoattenuated mass was likely a retained sponge element based on its radiological features. Additional surgical exploration identified the retained silicone sponge. This clinical photographic-radiological correlation of retained silicone sponges presenting as orbital inflammation reminds surgeons to meticulously explant buckle material. PMID:27413562

In 84 clinically evaluable patients, high cure rates were obtained for all treatment groups (64 to 85%). Patients who received amoxicillin-clavulanic acid had a much higher incidence of gastrointestinal side effects than did patients who received cefaclor (34 versus 3%, P less than 0.005). However, only five patients with gastrointestinal reactions to amoxicillin-clavulanic acid had symptoms severe enough to warrant halting the completion of antibiotic therapy. PMID:6362559

    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.

    Summary Background Common etiologies of scrotal swelling in neonates include hydrocoele, inguinal hernia and testicular torsion; less common is epididymo-orchitis. Congenital nephrotic syndrome (CNS), a rare entity, is known to present as progressive renal failure and its leading presentation with scrotal involvement has not been reported. Material/Methods We report a rare case of CNS with primary clinical presentation as scrotal cellulitis and epididymo-orchitis. In this neonate, scrotal and abdominal ultrasound examination was performed and the laboratory data were obtained. Results Sonography revealed bilaterally enlarged echogenic kidneys, testis and epididymis with echogenic peritoneal fluid tracking into both scrotal sacs. Laboratory data revealed proteinuria and severe depletion of serum IgG. Culture of the peritoneal fluid showed gram-negative organisms. A final diagnosis of CNS, complicated with peritonitis tracking into the scrotal sacs was arrived at. Conclusions CNS may have a rare presentation with distracting symptoms of scrotal cellulitis and epididymo-orchitis, as seen in our patient. However, diligent use of abdomino-scrotal sonography, supported by relevant laboratory data can clinch the accurate diagnosis. PMID:27757175

    Aims: This study was conducted retrospectively to define early demographic and clinical predictors for acute kidney injury (AKI) among snake bite patients at the time of hospital admission. Materials and Methods: We analyzed 138 cases with a poisonous snake bite. Patients were classified into two groups according to the presence and absence of AKI. The data regarding clinical features and demographic profile of these patients were collected from the hospital records in a prestructured pro forma and statistically compared. Results: Of the 138 patients of venomous snake bite, 62 developed AKI (44.92%). Patients who developed AKI were older in age. Moreover, prolonged bite to anti-snake venom (ASV) time had a significant relationship in developing AKI (P < 0.05). Among the clinical features, there was an independent positive association of AKI with abdomen pain, tenderness and vomiting, cellulitis, bleeding tendencies, myalgia, and black or brown urine (P < 0.05). Neurological features were inversely associated with renal involvement. Conclusion: We found that marked abdominal pain, tenderness and vomiting, myalgia, black or brown urine, bite site cellulitis, bleeding tendencies, and prolonged (>2 h) bite to ASV time were significantly associated with the development of AKI in snake bite patients.

    Staphylococcus aureus is a known pathogen in pediatric patients that produces skin infections, cutaneous abscess, cellulitis and osteoarticular infections. Most of these infections are produced by a meticilin susceptible strain. The community associated methicillin resistant Staphylococcus aureus was published for the first time in 1993, ever since then is has been recognized as a cosmopolite pathogen. The first report in Latin America was published in 2003, and in Chile in 2008 from adult patients that have reported traveling to other countries. The following series describes four pediatric cases, all school-aged children, diagnosed since 2012 with clinical followups and molecular studies. Two cases presented as osteomyelitis of the lower extremity; and one presented as arm cellulitis. These three cases had Panton Valentine leukocidine (PV-L) negative strains from the clone complex 8. The last case presented a renal abscess, the strain was PV-L positive from the clone complex 30. This case series constitutes the first pediatric case report in Chile. PMID:26230445

    Gram-positive Streptococcus pyogenes (group A Streptococcus or GAS) is a major skin pathogen and interacts with keratinocytes in cutaneous tissues. GAS can cause diverse suppurative and inflammatory infections, such as cellulitis, a common acute bacterial dermo-hypodermitis with a high morbidity. Bacterial isolation yields from the lesions are low despite the strong local inflammation observed, raising numerous questions about the pathogenesis of the infection. Using an in vitro model of GAS-infected keratinocytes, we show that the major ROS produced is the superoxide anion ([Formula: see text]), and that its production is time- and dose-dependent. Using specific modulators of ROS production, we show that [Formula: see text] is mainly synthesized by the cytoplasmic NADPH oxidase. Superoxide anion production leads to keratinocyte necrosis but incomplete inhibition of GAS growth, suggesting that GAS may be partially resistant to the oxidative burst. In conclusion, GAS-stimulated keratinocytes are able to develop an innate immune response based on the production of ROS. This local immune response limits GAS development and induces keratinocyte cell death, resulting in the skin lesions observed in patients with cellulitis.

    Chronic wounds such as diabetic foot ulcers, venous ulcers, and pressure ulcers are a major source of morbidity and mortality. To describe wound characteristics associated with a wound emergency, the Wound Electronic Medical Records (WEMR) of 200 consecutive admissions (139 patients, average number of admissions 1.4) to a dedicated inpatient wound healing unit over a period of 5 months were retrospectively reviewed. Patient mean age was 62 +/- 16 years, 59% were men, 27% had a foot ulcer and diabetes mellitus, and 29% had venous ulcers. Presenting signs and symptoms included wound pain, cellulitis, nonpurulent drainage, and undermining, but few presented with classic local clinical signs of infection. Treatment consisted of sharp debridement with deep tissue culture and pathology from the wound base and/or systemic antibiotics. Twenty-percent (20%) of patients had pathology-confirmed and 38% had pathology- or radiology-confirmed osteomyelitis on admission, supporting that new or increasing wound pain, cellulitis, and/or nonpurulent drainage or presence of significant undermining may be indicative of an invasive infection and that patients presenting with these signs and symptoms require an immediate treatment plan and consideration of hospital admission. Use of an objective documentation system such as the WEMR may help alert clinicians to subtle wound changes that require aggressive treatment; thereby, avoiding emergency room visits and hospital admissions. Future research is needed utilizing the WEMR across multiple medical centers to further define criteria for a chronic wound emergency.

    To assess the feasibility of remote management of extremity wound by using a mobile camera phone to transfer clinical images and online communication, teleconsultations were carried out on 60 patients between January and August 2003 for 82 extremity wounds presented to the emergency room between residents and consultant plastic surgeons. A questionnaire about wound descriptors (gangrene, necrosis, erythema, and cellulitis/infection), as well as clinical opinions regarding treatment with antibiotics or debridement, was filled out. In this study, 3 surgeons were able to make 80%, 76%, 66%, and 74% agreement, respectively, in the remote diagnosis regarding presence of gangrene, necrosis, erythema, and cellulitis/infection. Recognition of gangrene had the highest agreement percent (80%), sensitivity (85%), and specificity (93%). There were 68% to 90% of image sets that could be made with equivalent diagnoses of wound descriptors and 83% of wounds managed as per the remote treatment recommendation regarding whether to use antibiotics or to perform debridement. The preliminary results showed that the camera phone is valuable and bears potential for remote management of the extremity wound.

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

    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 μL of a brain-heart infusion (BHI) culture containing 1 × 10(8), 1 × 10(7), 1 × 10(6), 1 × 10(5), or 1 × 10(4) 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.

    La fibromatose desmoïde mammaire est une entité rare, mimant sur le plan clinique et échographique un cancer du sein. Seule l'histologie apportera le diagnostic en objectivant une prolifération de cellule fusiforme (fibro et myofibroblastique sans atypies nucléaires), agencée en faisceaux, mêlés à des bandes de collagène, sans composante épithéliale. Le diagnostic différentiel se pose essentiellement avec le carcinome métaplasique à cellules fusiformes. L’évolution est strictement locale, avec un grand pouvoir récidivant. L'exérèse chirurgicale complète avec des marges saines (jusqu’à 3cm) est le traitement de choix, la radiothérapie reste une option thérapeutique en complément de la chirurgie dans les exérèses incomplètes et en cas de récidives multiples. A travers notre cas et une revue de la littérature, nous essayerons de mettre le point sur le diagnostic de cette entité rare et de sa prise en charge puisqu'elle va conditionner le pronostic.

  2. Tufted folliculitis of the scalp: a distinctive clinicohistological variant of folliculitis decalvans.

    1998-05-01

    Tufted folliculitis is an uncommon folliculitis of the scalp that resolves with patches of scarring alopecia within which multiple hair tufts emerge from dilated follicular orifices. The clinicohistological data from a group of 15 patients with tufted folliculitis were reviewed and compared with those of seven patients with folliculitis decalvans, five with acne keloidalis nuchae, four with dissecting cellulitis of the scalp, three with kerion celsi and 20 with follicular lichen planus. It was found that tufted folliculitis could be differentiated from folliculitis decalvans only by finding several hair tufts scattered within patches of scarring alopecia. Histologically, a single tuft consisted of peculiar clustering of adjacent follicular units opening at the bottom of an epidermal depression. Conversely, the presence of keloidal plaques in acne keloidalis nuchae, coalescing nodules discharging purulent material in dissecting cellulitis of the scalp, erythematous plaques covered by pustules replete with fungal elements in kerion celsi, and the absence of follicular pustules in follicular lichen planus distinguished these diseases from tufted folliculitis. On the basis of these findings, it is suggested that tufted folliculitis should be considered as a distinctive clinicohistological variant of folliculitis decalvans. Tufting of hair is caused by clustering of adjacent follicular units due to a fibrosing process and to retention of telogen hairs within the involved follicular units. PMID:9666825

    Ludwig angina is a rapidly progressing submaxillary, submandibular, and sublingual necrotizing cellulitis of the floor of the mouth that can have lethal consequences due to airway obstruction. Various aerobic and anaerobic microorganisms, and less often fungi, have been implicated to cause Ludwig angina, including oral flora such as streptococci and staphylococci. Early recognition and the use of parenteral antibiotics can prevent mortality and morbidity. We report a case of a 25-year-old white man who was admitted to the hospital by his dentist after being diagnosed with Ludwig angina secondary to periodontal abscesses involving teeth #17 and #32. Although antibiotics were administered, while in the hospital, the decedent had difficulty swallowing and was drooling. He suddenly began to have seizure-like activity thought to be anoxic myoclonus. The decedent was aggressively resuscitated and taken to the operating room for neck exploration and a tracheostomy. Neck exploration revealed severe necrotizing acute inflammation of the deep soft tissues and musculature of the neck. He remained on life support for 7 days until he was declared brain dead. Ludwig angina is a progressive cellulitis that often results in death by asphyxia. Ludwig angina can be complicated by subsequent deep neck infection. The underlying etiologies and common scenarios are examined, and significant autopsy findings and dissecting procedures are discussed. The pathophysiology of Ludwig angina is studied with a review of the current literature. PMID:18725784

    Pigmented casts have been reported with variable frequency in scalp biopsies from alopecia areata, trichotillomania, chemotherapy-induced alopecia and postoperative (pressure induced) alopecia. Their presence and morphology in other scalp disorders has not been described. The authors assessed for the presence and morphology of pigmented casts in 308 transversely bisected scalp biopsies from nonscarring and scarring alopecia, referred to the Department of Dermatology, University of Miami within a year. The pigmented casts were present in 21 of 29 cases of alopecia areata (72%), 7 of 7 cases of trichotillomania (100%), 1 case of friction alopecia, 4 of 28 cases of central centrifugal cicatricial alopecia (14%), and 4 of 4 cases of dissecting cellulitis (100%). They did not show any distinguishing features except for the morphology in trichotillomania, which included twisted, linear (zip), and "button"-like pigment aggregation. The linear arrangement was found also in friction alopecia and dissecting cellulitis. Pigmented casts in the hair canals of miniaturized/vellus hairs was a clue to alopecia areata. Pigmented casts can be observed in biopsies of different hair disorders, but they are not specific for the diagnosis. Horizontal sections allow to better assess their morphology and the follicular level of presence of pigmented casts, which in the context of the other follicular findings may be a clue to the diagnosis.

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

    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.

    Background: The orbital complications account for about 80% of all complications secondary to acute rhinosinusitis. If the treatment is not correct and in time, orbital complications could progress rapidly, leading to optic neuritis, cavernous sinus thrombophlebitis or life-threatening intracranial complications. Aims: To evaluate the therapeutic efficacy of conservative therapy for the patients with orbital cellulitis and endoscopic sinus surgery (ESS) performed on patients with subperiosteal abscess (SPA) secondary to acute rhinosinusitis in children. Study Design: Retrospective cross-sectional study. Methods: The retrospective study included 31 pediatric patients with orbital complications secondary to acute rhinosinusitis. In all cases, intensive treatment was initiated with a combination of oral or intravenous antibiotics, glucocorticoid and gelomyrtol forte after admission. ESS was performed if an improvement in the condition of patients did not occur after 48 hours. However, the patients with orbital SPA, motility disorders of eyeball or decreased vision received ESS immediately within 24 hours. Results: Sixteen patients were cured by conservative therapy and 15 patients by ESS. All of the signs and symptoms disappeared after conservative therapy or ESS. There were no recurrences within the follow-up period of 1 to 8 years. Conclusion: Conservative therapy is an effective method for patients with inflammatory edema and most cases of orbital cellulitis in children. SPA can be cured by ESS.

    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

    Aim: Snakebite injuries are common in tropical India among those who are involved in outdoor activities. These injuries results in cellulitis, gangrene at the bite area, bleeding manifestations, compartment syndrome, regional lymphadenopathy, septicemia, hypotension, and disseminated intravascular coagulation (DIC) resulting in significant morbidity and mortality. The purpose of this study is to share our experience of multidisciplinary approach in the management of snakebite injuries of the extremities with various treatment modalities including hyperbaric oxygen (HBO) therapy, surgical debridement, and soft tissue reconstruction to provide an effective treatment for snake bite injuries. Methods: The study was conducted in the Department of Plastic Surgery, during the period October 2012–December 2014, wherein all the patients who were admitted with snakebite injuries were enrolled and the patients treated in plastic surgery department were included into the study. Out of total 766 patients, there were 323 patients treated with anti snake venom (ASV) and 29 died among the treated patients; 205 patients belonged to pediatric age group. Results: Out of 112 patients referred to Department of Plastic Surgery, 50 cases presented with cellulitis, 24 patients with compartment syndrome, and 38 patients were referred for the management of soft tissue cover over the extremities. Among 112 patients, 77 involved the lower extremity and 35 the upper extremity. Conclusion: Multidisciplinary approach including hyperbaric oxygen (HBO) therapy improves outcome in the management of snakebite injuries of the extremities. PMID:26862269

    2002-06-15

    THE DIAGNOSIS OF ACUTE BACTERIAL MAXILLARY SINUSITIS: Is based on at least two of three major criteria: sinus pain, unilateral signs, increasingly voluminous and purulent rhinorrhea. Minor criteria can also be retained for diagnosis if they persist for three days. THE NEED FOR ANTIBIOTIC THERAPY: In this diagnostic context is undeniable, similar to the situation after failure of symptomatic treatment or complication. Likewise for unilateral maxillary sinusitis due to homolateral infection of the superior dental archade or for frontal, ethmoidal, or sphemoïdal sinusities. THE MOST FREQUENTLY CAUSAL BACTERIA: Are Streptococcus pneumoniae and Haemophilus influenzae. For first intention treatment generally relies on beta-lactams (amoxicilin/clavulanic acid, second or third generation cephalosporins); pristinamycin may also be useful. Fluoroquinolones active against pneumococci, e.g. levofloxacin, are reserved for cases of sinusitis with risk of complications and for second line treatment after failure in patients with acute maxillary sinusitis. COMPLICATIONS OF SINUSITIS: Can result from anatomic anomalies or from infectious mechanisms such as metastasis of a locoregional infection: peri-orbital cellulitis, orbital cellulitis, thrombophlebitis of the cavernous sinus, extradural, subdural or intracerebral abscess. Three clinical trials are under way to assess efficacy in the treatment of complicated or high risk sinusitis.

    I paragangliomi sono tumori neuroendocrini derivati dalla cresta neurale, provenienti dai paragangli, organi neuroendocrini dispersi e caratterizzati da cellule producenti catecolamine e peptidi. Presentano un’incidenza annuale stimata in 1 / 100.000, rappresentando il 10% dei tumori secernenti catecolamine. Riportiamo il caso di un uomo di 76 anni giunto alla nostra osservazione per la presenza di una lesione polipoide di 4 cm, vegetativaulcerata, tra il corpo e dell’antro gastrico rilevata durante una gastroscopia per la comparsa di anemia. Il paziente è stato sottoposto a gastrectomia subtotale con omentectomia e anastomosi gastrodigiunale. L’esame istologico ha rivelato un carcinoma gastrico polipoide ulcerato con cellule scarsamente aderenti con infiltrazione della parete gastrica muscolare e incidentalmente è stata identificata una lesione della parete gastrica posteriore incidentale che si rilevava essre un paraganglioma con la positività alle indagini di immunocitochimica per NSE e negatività per CD117, S100, CD34 e SMA. Con il termine di feocromocitoma si indica esclusivamente i tumori derivanti dalla midollare del surrene, mentre il paraganglioma extra-surrenalico suggerisce tumori delle cellule cromaffini con altre posizioni. La localizzazione gastrica o perigastrica, come nel nostro caso, è molto rara per queste neoplasie, e in letteratura vi sono solo pochi case report. La predisposizione genetica si osserva nel 30% di questi tumori e può essere responsabile della malattia ereditaria caratterizzata da differenze nella distribuzione del tumore, nella produzione di catecolamine, nel rischio di metastasi, e nell’associazione con altri tipi di tumori. In conclusione, nei pazienti con sintomi di tumore secernente cromaffini o in pazienti con una storia familiare di feocromocitoma-paraganglioma, che portano mutazioni e sottoposti a screening per il tumore asintomatico, la prima indagine diagnostica è determinare i livelli di metanefrina

    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

    This article presents a case of bilateral ethmoid sinusitis with unilateral proptosis as a presenting sign of an unsuspected prostate carcinoma. A 59-year-old Hispanic male presented to his primary care physician with nasal congestion and rhinitis. He was treated with antibiotics and antihistamine decongestants for 3 weeks without improvement. A trial of steroids resulted in brief improvement followed by a rapid onset of nasal obstruction with proptosis. A computed tomography scan revealed opacification of the ethmoid sinus with right proptosis. The presumptive diagnosis was orbital cellulitis secondary to chronic ethmoid sinusitis. Endoscopic sinusotomy and bilateral ethmoidectomies were performed. Biopsy results returned as metastatic adenocarcinoma, probably of prostate origin. Urological work-up and evaluation with biopsy confirmed the diagnosis of prostatic carcinoma. The patient was treated with chemotherapy and radiation therapy. He died 7 months later with disseminated disease. Images Figure 1 Figure 2 Figure 3 Figure 4A Figure 4B PMID:7861473

    We compared the activities of tedizolid to those of linezolid and other commonly used antimicrobial agents against gram-positive cocci recovered from patients with skin and skin structure infections (SSSIs) and hospital-acquired pneumonia (HAP) in Korean hospitals. Gram-positive isolates were collected from 356 patients with SSSIs and 144 patients with HAP at eight hospitals in Korea from 2011 to 2014. SSSIs included impetigo, cellulitis, erysipelas, furuncles, abscesses, and infected burns. Antimicrobial susceptibility was tested by using the CLSI agar dilution method. All of the gram-positive isolates were inhibited by ≤1 μg/mL tedizolid. The minimum inhibitory concentration [MIC]₉₀ of tedizolid was 0.5 μg/mL for methicillin-resistant Staphylococcus aureus, which was 4-fold lower than that of linezolid. Tedizolid may become a useful option for the treatment of SSSIs and HAP caused by gram-positive bacteria. PMID:26206690

    We describe the first case of a psoas muscle abscess caused by Nocardia beijingensis and subcutaneous phaeohyphomycosis caused by Phaeoacremonium parasiticum in a renal transplant recipient. The patient was treated for nocardiosis with percutaneous drainage and intravenous trimethoprim/sulfamethoxazole (TMP/SMX) combined with imipenem for 2 weeks, followed by a 4-week course of intravenous TMP/SMX and then oral TMP/SMX. During hospitalization for the psoas muscle abscess the patient developed cellulitis with subcutaneous nodules of his right leg. Skin biopsy and cultures revealed a dematiaceous mold, subsequently identified as P. parasiticum by DNA sequencing. The subcutaneous phaeohyphomycosis was treated with surgical drainage and liposomal amphotericin B for 4 weeks followed by a combination of itraconazole and terbinafine. The patient gradually improved and was discharged home after 18 weeks of hospitalization. PMID:26867363

    An epizootic in white Saanen goats, caused by Mycoplasma mycoides subsp. mycoides is described. Twenty-five flocks totalling approximately 4,500 animals were involved. The disease was characterized by a high, transient temperature, general malaise and mastitis in the lactating does, and a keratoconjunctivitis, arthritis, mycoplasmaemia and death among the kids. In one goat flock there was a precipitous change in the character of the disease, from a predominantly mastitis syndrome to a fulminating pleuropneumonia. In another goat flock, twin kids were born with an advanced purulent, proliferative arthritis, suggesting early congenital infection. In yet another infected flock there were cases of subcutaneous abscesses from which both M. mycoides and Corynebacterium pyogenes were cultured. M. mycoides was also isolated from synovial fluid and the parenchymal organs of an Ibex mountain goat that died of a purulent polyarthritis. Experimental infection in kids caused a diffuse cellulitis at the site of inoculation, a high fever, polyarthritis and death.

    Orbital emphysema is generally recognized as a complication of orbital fractures involving any paranasal sinuses. The recognition about its etiology has extended beyond sole trauma, but few articles mentioned tumors to be a possible cause.In this case report, we present a patient with orbital emphysema associated with ethmoid osteoma without orbital cellulitis or trauma history. The patient developed sudden proptosis, eyelid swelling, and movement limitation of the left eye, peripheral diplopia, and left periorbital crepitus after a vigorous nose blowing.Complete surgical resection of ethmoid osteoma followed by repair of the orbital medial wall was performed with assistance of combined endoscopy and navigational techniques. Twelve-month follow-up showed no residual lesion or recurrence; the orbital medial wall was accurately repaired with good visual function and facial symmetry.Tumors should be considered for differential diagnosis of orbital emphysema, and combined endoscopy and navigational techniques may improve safety, accuracy, and effectiveness of orbital surgeries.

    Skin and soft tissue infections (SSTIs) are a common cause of hospital admission among elderly patients, and traditionally have been divided into complicated and uncomplicated SSTIs. In 2010, the FDA provided a new classification of these infections, and a new category of disease, named acute bacterial skin and skin structure infections (ABSSSIs), has been proposed as an independent clinical entity. ABSSSIs include three entities: cellulitis and erysipelas, wound infections, and major cutaneous abscesses This paper revises the epidemiology of SSTIs and ABSSSIs with regard to etiologies, diagnostic techniques, and clinical presentation in the hospital settings. Particular attention is owed to frail patients with multiple comorbidities and underlying significant disease states, hospitalized on internal medicine wards or residing in nursing homes, who appear to be at increased risk of infection due to multi-drug resistant pathogens and treatment failures. Management of ABSSSIs and SSTIs, including evaluation of the hemodynamic state, surgical intervention and treatment with appropriate antibiotic therapy are extensively discussed. PMID:27084183

    A new enterostomy tube placement technique is described for provision of nutrients into the duodenum. Placement of the duodenostomy tube (d-tube) is performed through a limited right flank approach under sedation and local anesthesia. Seven client-owned animals (three dogs and four cats) requiring enteral nutritional support were selected for d-tube placement. Patients were fed via the d-tube for two to 28 days. Complications included discomfort when manipulating and exteriorizing the duodenum, discomfort with bolus feedings, local cellulitis, and tube site infection. All complications resolved without further incident. This technique should be considered in patients that are not good candidates for prolonged general anesthesia or esophageal or gastric feeding, or patients being mechanically ventilated.

    The hallmarks of X-linked Agammaglobulinemia (XLA) are panhypogammaglobulinemia, absent B-cells, and recurrent sinopulmonary and gastrointestinal infections starting at an early age, as well as other infections like cellulitis, meningitis, arthritis and sepsis. A number of non-infectious complications have been reported in these patients, including autoimmune diseases and malignancy, especially lymphomas. Here, we report the case of a 30-year old man who developed gastric adenocarcinoma in the context of XLA. Previous reports of, and hypotheses addressing the development of cancer in patients with XLA, are also summarized. Solid cancer in XLA affects mainly the gastrointestinal tract and seems to be related to chronic infection. A natural evolution can be traced back from gastric adenocarcinoma to megaloblastic anemia due to achlorhydria in the context of chronic infection; periodic endoscopy thus seems justified to detect and treat carcinoma in early stages.

    Inappropriate prescribing of antibiotics by health care professionals is a worldwide concern. This study evaluated the knowledge and practices of dental practitioners in the city of Shiraz, Islamic Republic of Iran regarding their therapeutic use of antibiotics for patients with dentoalveolar infections. Of 219 (48.6%) dentists responding to the questionnaire more than 40% would prescribe antibiotics for localized fluctuant swelling and for problems for which antibiotics are not required according to good practice guidelines (acute pulpitis, chronic apical infection, periodontal abscess, chronic gingivitis, chronic periodontitis, pericoronitis and dry socket). A majority correctly prescribed antibiotics for acute periapical infection (77.2%), cellulitis (75.3%) and acute ulcerated gingivitis (63.0%). Amoxicillin was the most frequently prescribed antibiotic for all clinical conditions but there was a wide variation in dosage, frequency and duration for all antibiotics used. Guidelines on rational antibiotic use are needed for dental practitioners in the Islamic Republic of Iran.

    2014-01-01

    Background We describe a minimally invasive surgical technique, tracheostomaplasty, to overcome anatomical deformities of the stoma that preclude successful retention of a stoma button for hands free tracheoesophageal (TE) speech. Methods We conducted a retrospective analysis of 21 patients who underwent tracheostomaplasty after laryngectomy to accommodate an intraluminal valve attachment for hands-free TE speech. Results Sixteen men and 5 women (median age, 65 years; median follow-up, 27.7 months) underwent tracheostomaplasty; 6 patients developed a mild cellulitis that required therapy and 5 patients required a minor revision surgery. At last follow-up, 15 (71%) patients successfully achieved hands-free TE speech using an intraluminal stoma button. Three patients only retained the intraluminal device to facilitate digital occlusion. Tracheostomaplasty failed in 3 patients because of granulation tissue formation or stomal stenosis. Conclusions Tracheostomaplasty is a successful technique to improve intraluminal retention of a stoma button for hands-free TE speech in laryngectomy patients. PMID:20848405

    Postpartum infections remain a leading cause of neonatal morbidity and mortality worldwide. A high percentage of these infections may stem from bacterial colonization of the umbilicus, because cord care practices vary in reflection of cultural traditions within communities and disparities in health care practices globally. After birth, the devitalized umbilical cord often proves to be an ideal substrate for bacterial growth and also provides direct access to the bloodstream of the neonate. Bacterial colonization of the cord not infrequently leads to omphalitis and associated thrombophlebitis, cellulitis, or necrotizing fasciitis. Various topical substances continue to be used for cord care around the world to mitigate the risk of serious infection. More recently, particularly in high-resource countries, the treatment paradigm has shifted toward dry umbilical cord care. This clinical report reviews the evidence underlying recommendations for care of the umbilical cord in different clinical settings. PMID:27573092

    Raoultella species are Gram-negative, non-motile bacilli primarily considered to be environmental bacteria. Raoultella planticola is a rare cause of human infections. We report a case of serious soft-tissue infection in a young male tiler who presented with cellulitis of his left thumb. He had sustained a crush injury to his left thumb 10 days earlier in a soiled environment. He noted a minor break in the skin and he washed the wound out with running water. One week later, he experienced pain, erythema, and swelling of his thumb and attended his general practitioner who prescribed oral flucloxacillin and penicillin V. Despite this treatment, he noticed progressive erythema and swelling of his thumb requiring hospital admission 3 days later. He underwent washout and debridement of his thumb. Tissue obtained intraoperatively cultured Raoultella planticola. He was treated with broad-spectrum antibiotics including ciprofloxacin and made a full and rapid recovery.

Her past medical history was remarkable for DM type 2, hypertension, and hypothyroidism. Upon admission, examination showed bilateral warmth and tender soft tissue swelling around the knees and MRI showed cellulitis of distal thirds of both thighs. The next day, the patient became drowsy. Neurologic examination showed neck rigidity and right sided hemiparesis. Cerebrospinal fluid and blood cultures yielded group B streptococcus sensitive to ceftriaxone, penicillin G, and vancomycin. The patient received ceftriaxone for a total of 14 days after which she improved and was discharged from the hospital with right sided weakness. PMID:26904325

    Mycobacteium chelonae is a rapidly growing atypical mycobacteria known to be pathogenic in humans. We report a case of Hidradenitis Suppurativa (HS) with diabetes complicated by infection of the lesions with Staphylococcus aureus and M. chelonae leading to non-healing and discharging lesions. HS is a rare, insidious and debilitating disease characterized by swollen, painful, inflamed lesions in the axillae, groin, and other parts of the body that contain apocrine glands. Discharge from HS lesions are often found to be sterile, however, polymicrobial bacterial colonization commonly occurs within sinus tracts which can lead to offensive smelling discharge, infection, cellulitis, and superinfection. The incidence of HS is very low and the association with M. chelonae makes it a rare and interesting case. PMID:24350020

    A woman in her 60s with type 2 diabetes presented with a 4-week history of a rash on her chest wall, flu-like symptoms and a red right eye. On examination, there was a cellulitic rash over the right chest wall, breast and neck and a hypopyon in the right eye. Chest x-ray demonstrated right upper lobe opacification, with subsequent CT and MRI revealing bilateral collections at the lung apices, and a possible permeative bone destruction of the manubrium, respectively. A diagnosis of primary sternal osteomyelitis with associated lung abscesses, chest wall cellulitis and hypopyon due to endogenous endophthalmitis was made, with microbiological assessment identifying group B β-haemolytic streptococci. The patient underwent surgical debridement of the affected tissue and received 6 weeks of intravenous antibiotics. This case highlights the role of multidisciplinary team involvement in management of infections and the need to consider deep-seated infection in diabetics.

    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.

    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.

    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.

    Metastatic Crohn disease is a rare cutaneous manifestation of Crohn disease characterized by granulomatous lesions discontinuous with the diseased areas of the gastrointestinal tract. We report a case of a 32-year-old woman with history of Crohn disease who was admitted for treatment of cellulitis after presenting with a tender erythematous plaque of the left calf. Microbiological tests including tissue cultures were negative. A skin biopsy revealed granulomatous dermatitis consistent with metastatic cutaneous Crohn disease. Owing to concomitant perianal fistulas and abscesses and prior infusion reaction to infliximab, the patient was treated with certolizumab, a pegylated tumor necrosis factor (TNF) inhibitor combined with methotrexate resulting in complete resolution of the skin lesion. This case emphasizes the importance of recognizing this rare skin manifestation of Crohn disease and adds certolizumab as one of TNF inhibitors useful in the treatment of metastatic cutaneous Crohn disease.

    In case of complex anal fistulae, the treatment can include muscular flaps. The gracilis transposition flap is the gold-standard in perineal reconstructive surgery, with wide use during the past decades. However, in some cases, this flap is too short to reach difficult locations such as the posterior perineum. The long head of the biceps femoris, which has already been studied in the electrically stimulated neosphincter formation, could be more appropriate in such clinical situations. Furthermore, its potential advantages, amongst which an excellent functional outcome, would be to allow persistent prone position, during both treatment and reconstruction, as well as a more favorable intramuscular vascularisation. We report the case of a 39-year-old man with a complex recurrent transphincteric posterior anal fistula with an external orifice in the right buttock and complicated with a severe cellulitis, treated with an endo-anal flap combined with a long head of biceps femoris pediculised flap.

    The present study reports the case of a 58-year-old male patient who repeatedly presented with hand ulcers that were diagnosed as cellulitis. Upon histological analysis, however, an inflammatory myofibroblastic tumor (IMT) was diagnosed. IMTs rarely occur in the hands. The involved tissue was removed with the tumor, with the exception of the tendons and cutaneous nerve. The involved tendon sheath and epineurium were carefully resected. After 2 years of follow-up, the patient showed no signs of tumor recurrence and the hand function was good. IMTs in the hands are relatively rare, and are often easily misdiagnosed as infection. An early and correct diagnosis is the key to successful treatment. A biopsy is necessary following debridement of the infected lesion, particularly for recurrent infected lesions. The surgical approach should be conservative, in order to maintain maximum hand function. PMID:26137104

    Ligneous conjunctivitis, secondary to inherited homozygous plasminogen deficiency, is a poorly understood condition that has the potential to hinder normal childhood development if not managed adequately. We report the clinical progression of a child with ligneous conjunctivitis, controlled with daily heparin eye drops, postsurgical excision, for a duration of approximately 5 years at a cost of approximately 30 USD per month. During this time, the patient's progress has been complicated by one occurrence of periorbital cellulitis and also otitis media. The patient has also experienced ocular complications due to the remaining membranous lesion. This case indicates that individual patient factors including plasminogen levels and exposure to triggers of ocular inflammation may influence the clinical progression of ligneous conjunctivitis. Furthermore, this study is one of the first to present over 5-year follow-up of a patient with ligneous conjunctivitis effectively managed with long-term heparin eye drops.

    Scarring alopecia or cicatricial alopecia results from follicular damage that is sufficient to cause the destruction and replacement of pilosebaceous structures by scar tissue. Primary scarring alopecias represent a group of disorders that primarily affect the hair follicles, as opposed to secondary scarring alopecias, which affect the dermis and secondarily cause follicular destruction. Inflammation may predominantly involve lymphocytes or neutrophils. Cicatricial alopecias that mainly involve lymphocytic inflammation include discoid lupus erythematosus, lichen planopilaris, frontal fibrosing alopecia, central centrifugal alopecia, and pseudopelade (Brocq). Cicatricial alopecias that are due to predominantly neutrophilic inflammation include folliculitis decalvans, tufted folliculitis, and dissecting cellulitis of the scalp. Folliculitis keloidalis is a cicatricial alopecia with a mixed inflammatory infiltrate. PMID:26370646

    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

    To evaluate the role of ultrasound (US) in the detection of osteomyelitis, the authors prospectively studied 48 patients clinically suspected of having osteomyelitis. A sonographic diagnosis was made if fluid was seen directly in contact with bone, without intervening soft tissues. Twelve of the 48 patients were subsequently found to have osteomyelitis. In 10 of them, US demonstrated abnormal fluid adjacent to the bone. This fluid was thought to represent an inflammatory exudate dissecting in a subperiosteal and/or extraperiosteal location. Eight of the 48 patients had soft-tissue fluid collections. The rest of the patients either had no abnormalities or had cellulitis. The authors conclude that US can be useful in the detection of osteomyelitis. PMID:2664872

    Intravenous drug injection persists despite health risks and medical complications. Venous thrombosis, septic thrombophlebitis, artery necrosis, arterio-venous fistula, mycotic aneurysm, dissecting hematoma, pseudoaneurysm formation, and soft tissues infections (i.e. abscesses, cellulitis, infected ulcers), are some of the major clinical consequences lives threatening. The aim of this work is to present this unusual autoptic case of a drug addict man died for an unrecognized groin abscess referred to the Institute of Legal Medicine, University of Chieti, causing femoral vein's erosion, and to analyse the most common patterns of vascular lesions among drug addicts. It could be stimulated a new scientific debate because groin injections and their vascular complications increase over years; while soft tissue infections may hide vascular lesions' diagnosis. So physicians should have a high index of suspicion for serious vascular problems, among intravenous drug users (IDUs): prevention for avoiding groin injection and a proper treatment are necessary.

    The management of hair and scalp conditions is difficult in any patient, especially given the emotional and psychological implications of hair loss. This undertaking becomes even more challenging in the ethnic patient. Differences in hair care practices, hair shaft morphology, and follicular architecture add complexity to the task. It is imperative that the physician be knowledgeable about these practices and the phenotypic differences seen in ethnic hair in order to appropriately diagnose and treat these patients. In this chapter, we will discuss cultural practices and morphologic differences and explain how these relate to the specific disorders seen in ethnic populations. We will also review the most prominent of the ethnic hair conditions including acquired trichorrhexis nodosa, traction alopecia, central centrifugal cicatricial alopecia, pseudofolliculitis barbae, dissecting cellulitis, and acne keloidalis nuchae.

    Perifolliculitis capitis abscedens et suffodiens (or dissecting folliculitis of the scalp or dissecting cellulitis of the scalp or dissecting perifolliculitis of the scalp) is a rare entity and constitutes the equivalent over the scalp, of hidradenitis suppurativa and acne conglobata. Etiologic factors are unknown. Diagnosis is proven histologically. Management is very difficult and consists in systemic administration or intralesional injection of several drugs or in surgical manipulations. An 18 year-old white patient with cystic infiltrations, alopecia plaques, pustules and other inflammatory elements (clinicohistological features consistent with dissecting folliculitis of the scalp), is presented. Isotretinoin topical application assured successful control of the disease and averted the evolution of the clinical aspect to scarring alopecia and nodule formation. Topical isotretinoin exercises a curative, inhibitory and antiproliferative action, in perifolliculitis capitis abscedens et suffodiens. PMID:12695138

    Abstract: A female American kestrel (Falco spaverius) fledgling was found on the ground with a suspected trauma to the right eye and open-mouth breathing. During the first 2 days of hospitalization, the bird developed severe bilateral periorbital cellulitis, blepharoedema, and sinusitis. The periocular tissues of the right globe were devitalized and communicated with a fistula at the commissure of the right side of the beak. The blepharoedema of the left eye was aspirated and yielded a dark colored malodorous fluid, which was submitted for aerobic bacterial and Mycoplasma cultures. Results showed a mixed infection with Mycoplasma buteonis, Avibacterium gallinarum, and Staphylococcus pasteuri, all of which are not commonly isolated from birds of prey. With antimicrobial therapy, supportive care, and surgical debridement of the right periocular necrotic tissues and adhesed phthisical globe, the kestrel recovered from this severe mixed upper respiratory infection.

    Langerhans cell histiocytosis (LCH) is an uncommon multisystem disease with an abnormal polyclonal proliferation of Langerhans cells that invade various organs. In rare instances, the affection of the orbit is the only and the first symptom. We report an unusual case of an 18-month-old male who presented with orbital disease as the first symptom, in the form of chronic presentation of periorbital swelling (2 months duration) with acute inflammation (1-week duration) giving a suspicion of orbital cellulitis. Histopathology after radical excision confirmed the diagnosis of LCH and was advised initial therapy as per Histiocyte Society Evaluation and Treatment Guidelines (2009) but was lost to follow-up only reappearing with progression (multisystem LCH with risk organ involvement) and developed progressive active disease on treatment after 5 weeks. He was treated with salvage therapy for risk patients achieving complete remission. PMID:26167225

    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.

    Pott's puffy tumor is a rare complication of frontal sinusitis characterized by swelling and edema in the brow due to a subperiosteal abscess associated with frontal osteomyelitis. Added complications are cellulitis by extension to the orbit and intracranial infection by posterior extension, with high risk of meningitis, intracranial abscess, and venous sinus thrombosis. Early diagnosis and aggressive medical or surgical treatment are essential for optimal recovery of affected patients. In the antibiotic age it is extremely rare, with very few cases described in the recent literature. A case is presented of a Pott inflammatory tumor in a 7 year-old boy, as a complication of acute pansinusitis who presented with front preseptal swelling and intracranial involvement with thrombosis of ophthalmic and superior orbital veins and frontal epidural abscess extending to the subarachnoid space.

We report a case of an elderly lady with multiple myeloma on treatment and uncontrolled diabetes, who developed loss of vision, swelling and redness of left eye of 4 days duration. There was no history of injury or entry of a foreign body. She also had left arm cellulitis. Ocular examination revealed visual acuity of 6/36 in right eye and no perception of light in left eye. Anterior segment of the right eye was insignificant while the left eye showed features suggestive of panophthalmitis. B scan revealed choroidal detachment and confirmed panophthalmitis. She underwent evisceration of the left eye. The cause of spontaneous infections is an immunocompromised state due to multiple myeloma and uncontrolled diabetes. This case report highlights the propensity of multiple myeloma to cause infections of the eye debilitating enough to cause severe visual morbidity. PMID:27630876

    The formation of special nanostructure, cellular structure, in Nd 4.5Fe 73.8B 18.5Cr 0.5Co 1.5Nb 1Cu 0.2 nanocomposite magnet has been observed by means of SEM for the first time. Ultrafine structure of cellules with thickness of 20-25 nm and length in range of 200-300 nm leads to high shape anisotropy of the materials. Therefore, high hard magnetic properties were obtained with ( BH) max up to 17.3 MG Oe in ribbons with very high remanence of 13.5 kG. The role of Cr and Co in the formation and refinement of cellular structure is proposed. Effect of heat treatment on hard magnetic properties is discussed in detail.

    During November 2008 to January 2009, 11 babies in the neonatal intensive care (NICU) and three babies in the nursery were infected with Serratia marcescens at King Abdulaziz University Hospital in Saudi Arabia. Overall, fifteen infections were identified among 11 newborns in the NICU: septicaemia (five cases), purulent conjunctivitis (three), urinary tract infection (two), meningitis (two) and cellulitis (one). Three newborns in the nursery had three infections: purulent conjunctivitis (two cases) and omphalitis (one). Thirteen of 14 babies recovered fully but one died from S. marcescens meningitis and septicaemia. All infections were traced to intrinsically contaminated baby shampoo introduced to the units five days before the first reported case. The outbreak terminated following withdrawal of the shampoo product.

    Any adult with diabetes in the tropics with hand cellulitis, infection and gangrene qualifies for tropical diabetic hand syndrome (TDHS). We reviewed a 39-year-old woman with a 3-week history of swelling of the left index finger following an insect bite. The swelling progressively increased in size, was very painful, and extended to the palm. There was no history or symptoms suggestive of chronic complications of diabetes. Random blood sugar on presentation was above 600 mg/dl using a glucometer. Examination revealed an edematous left palm draining pus from multiple sinuses, necrotic and gangrenous left index finger extending down to just above the thenar eminence. A diagnosis of TDHS in a patient with hyperosmolar state was made. She was managed accordingly and subsequently underwent aggressive debridement and desloughing. Two fingers were amputated and the wound was allowed to heal by secondary intention. PMID:27057390

    Skin tears are a common phenomenon in elderly institutionalized adults (EIAs). Incidence ranges from 0.92 to 2.5 per person/year. Little supportive literature exists regarding optimal treatment with many regimens reported. A convenience sample of 20 patients with Payne-Martin Category II and III skin tears of less than 8 hours' duration were prospectively evaluated with the use of a formulated 2-octylcyanoacrylate topical bandage. Patients were followed weekly until the tear healed. Complete healing occurred with 1 application of 2-OTB in 90% (18/20) of study subjects; 5% (n = 1) reported transient mild pain (less than 15 seconds), and 90% (n = 19) reported no pain. There were no incidents of cellulitis or infection. Shower and bathing routines were not interrupted. Cost averaged less than $1 per application. Clinician time averaged 1.5 minutes per application. Clinicians reported high satisfaction because repeated dressing changes were eliminated.

    Introduction and Objective. The Nuss procedure is widely used in the treatment of pectus excavatum worldwide. Postoperative pectus bar infection is one of the most serious complications associated with this procedure. Therefore, early detection of signs of implant infection is very important. However, this is difficult, and effective methods have yet to be established. Methods. We use a handheld infrared thermal imaging camera to screen patients for postoperative infection following the Nuss procedure. Here, we report a 28-year-old man with recurrent postoperative (Ravitch procedure) pectus excavatum. Results. Infrared thermography camera clearly indicated slight cellulitis in the right chest. Conclusion. Our technique may assist in preventing postoperative bar infection and removal caused by severe bar infection. Furthermore, this camera is potentially suitable for many situations in infection monitoring following subcutaneous implant surgery.

    Skin diseases are numerous and a frequently occurring health problem affecting all ages from the neonates to the elderly and cause harm in number of ways. Maintaining healthy skin is important for a healthy body. Many people may develop skin diseases that affect the skin, including cancer, herpes and cellulitis. 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

We present a case of a 37-year-old man presenting with pain and swelling in the groin following injection of heroin into the area. He was initially treated for severe cellulitis, however, he failed to respond to appropriate antimicrobial therapy. He went onto develop a widespread rash; it was then that a diagnosis of injectional anthrax infection was considered. Appropriate investigations were initiated including serum sample and tissue biopsy, and the diagnosis was confirmed. Management included extensive surgical debridement and a prolonged course of combination antibiotic therapy. The authors summarise the important steps in diagnosis and the management options in patients presenting with this life-threatening infection. PMID:24526196

    Animal bites are frequently encountered in the emergency department (ED). Aortitis leading to mycotic abdominal aortic aneurysm is a rare and potentially deadly complication of Pasteurella multocida (P. multocida) following an animal bite. We present the case of a 68-year-old male who presented to the ED after falling at home. He complained of weakness and abdominal pain. He was in septic shock and was treated empirically with broad-spectrum antibiotics and intravenous fluids. He reported previous antibiotic treatment of a cellulitis secondary to a cat bite injury to his right thumb four weeks prior. Abdominal ultrasound and subsequent computed tomography scan revealed a leaking mycotic abdominal aneurysm that was surgically repaired. Blood cultures and aortic wall tissue cultures grew P. multocida. Given how common animal bite presentations are in the ED, this case highlights the need to consider aortitis and mycotic abdominal aortic aneurysm in an unwell patient with an animal bite.

    The bacterium Aeromonas hydrophila is an anaerobic gram-negative bacillus commonly found in natural bodies of water and can cause infection in patients who suffer water-associated trauma or in immunocompromised hosts. The authors present 5 cases of penetrating wound trauma that did not involve any aquatic environment and developed rapidly forming infections. All patients presented with severe pain, cellulitis, ascending lymphangitis, fever, and pain on range of motion of the joint near the traumatic site. Presentation of clinical symptoms mimicked that of a septic joint or of severe streptococcal infection. All patients required surgical incision and drainage, intravenous and oral antibiotics using levofloxacin or bactrim, and local wound care. Results from cultures taken intraoperatively showed only A hydrophilia in every case. Resolution of symptoms occurred rapidly after surgery, and clinical resolution was seen within 72 hours. Each patient healed uneventfully and returned to preinjury status.

    Necrotizing fasciitis is a rapidly evolving, potentially fatal infection. Current recommendations advocate antibiotic administration and early aggressive surgical debridement. Aggressive surgery is associated with significant morbidity, leaving patients with substantial tissue loss and complex wounds. A case of suspected necrotizing fasciitis treated with minimal surgery is described. A previously healthy 48-year-old man presented with increased erythema, swelling and blistering of his left upper extremity. Despite a benign systemic clinical presentation, the hand and forearm were suspicious for necrotizing fasciitis, prompting surgical treatment. Surgical exploration found a significant amount of intradermal and subdermal clear fluid. It was decided to limit the amount of debridement. The diagnosis was Wells syndrome, eosinophilic cellulitis. Treated with steroids, the wounds healed uneventfully. It is important to consider the complete clinical picture before aggressive surgical treatment. A negative history for diabetes, atypical clinical presentation and benign operative findings are suggestive of a more benign diagnosis. PMID:23997598

    The authors present the complications due to subcutaneous injections on two patients suffering from morbid obesity with an abdomen pendulum. In the first case, injections of heparin of low molecular weight at curative dose, for treatment of a pulmonary embolism, have been complicated with a giant abdominal wall haematoma, the biggest ever reported. The initial treatment was insufficient so we had to practice a dermolipectomy to take off the haematoma of four litters. In the second case, insulin injections were complicated with cellulitis of the abdominal wall and a surgical treatment has been practiced in emergency. The first case reminds us the importance to change the sites of injections and to accommodate the dose, surgical treatment staying as simple as possible. The second case allows us to report a rare complication, not often published but known with obese patients. These two cases illustrate the importance of therapeutic education of the patient and the fact that a simple injection can be life threatening.

    Morganella morganii belongs to the tribe Proteeae of the Enterobacteriaceae family. This species is considered as an unusual opportunistic pathogen that mainly causes post-operative wound and urinary tract infections. However, certain clinical M. morganii isolates present resistance to multiple antibiotics by carrying various resistant genes (such as blaNDM-1, and qnrD1), thereby posing a serious challenge for clinical infection control. Moreover, virulence evolution makes M. morganii an important pathogen. Accumulated data have demonstrated that M. morganii can cause various infections, such as sepsis, abscess, purple urine bag syndrome, chorioamnionitis, and cellulitis. This bacterium often results in a high mortality rate in patients with some infections. M. morganii is considered as a non-negligent opportunistic pathogen because of the increased levels of resistance and virulence. In this review, we summarized the epidemiology of M. morganii, particularly on its resistance profile and resistant genes, as well as the disease spectrum and risk factors for its infection.

    The incidence of skin infections caused by Serratia marcescens is extremely low and such infections are typically observed in immunocompromised patients. The clinical manifestations of these infections include cellulitis, abscesses, fluctuant nodules, or granulomatous lesions. Infections caused by S. marcescens are very difficult to treat due to their resistance to many antibiotics, which often leads to specific and prolonged treatment. Infections after receiving a tattoo are very rare and are caused by unhygienic conditions or the inexperience of the tattooist. In this paper we present the case of a 32-year-old male with no comorbidity, who presented an abscess caused by S. marcescens in a area that was tattooed one month earlier. The case was resolved with surgery and antimicrobial therapy that was based on the antibiogram. To our knowledge, this is the first reported case of a S. marcescens skin infection following a tattoo, in the absence of immunosuppression. PMID:26356072

The aim of this work is to present this unusual autoptic case of a drug addict man died for an unrecognized groin abscess referred to the Institute of Legal Medicine, University of Chieti, causing femoral vein's erosion, and to analyse the most common patterns of vascular lesions among drug addicts. It could be stimulated a new scientific debate because groin injections and their vascular complications increase over years; while soft tissue infections may hide vascular lesions' diagnosis. So physicians should have a high index of suspicion for serious vascular problems, among intravenous drug users (IDUs): prevention for avoiding groin injection and a proper treatment are necessary.

    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.

    Langerhans cell histiocytosis (LCH) is an uncommon multisystem disease with an abnormal polyclonal proliferation of Langerhans cells that invade various organs. In rare instances, the affection of the orbit is the only and the first symptom. We report an unusual case of an 18-month-old male who presented with orbital disease as the first symptom, in the form of chronic presentation of periorbital swelling (2 months duration) with acute inflammation (1-week duration) giving a suspicion of orbital cellulitis. Histopathology after radical excision confirmed the diagnosis of LCH and was advised initial therapy as per Histiocyte Society Evaluation and Treatment Guidelines (2009) but was lost to follow-up only reappearing with progression (multisystem LCH with risk organ involvement) and developed progressive active disease on treatment after 5 weeks. He was treated with salvage therapy for risk patients achieving complete remission. PMID:26167225

    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

    The aim of this study was to investigate the effect of retinol on the human adipose conversion process using primary cultured human adipocyte precursor cells. When these cells were seeded in a medium containing retinol (concentrations ranging from 3.5 nM to 3.5 muM), cell proliferation was slightly inhibited by high concentrations of retinol, as demonstrated by cell counting and [(3)H]-thymidine incorporation. Moreover, the differentiation capacities of these cells were markedly and dose-dependently inhibited by retinol, as shown by the reduced expression of the lipogenic enzyme glycerol-3-phosphate dehydrogenase and by microscopic morphological analysis. These results strongly suggest that retinol, by inhibiting the ability of human preadipocytes to convert into mature adipocytes, could be of potential interest in the prevention of human adipose tissue development in general and of cellulitis in particular.

    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.

    ASBSTRACT Disinfection should be required for all skin penetrative procedures including parenteral administration of vaccines. This review analyses medically attended infectious events following parenteral vaccination in terms of their microbiological aetiology and pathogenesis. Like ‘clean’ surgical site infections, the major pathogens responsible for these events were Staphylococcal species, implicating endogenous con-tamination as a significant source of infection. As 70% isopropyl alcohol swabbing has been shown to effectively disinfect the skin, it would be medico-legally difficult to defend a case of sepsis with the omission of skin disinfection unless the very low risk of this event was adequately explained to the patient and documented prior to vaccination. There was a significant cost-benefit for skin disinfection and cellulitis. Skin disinfection in the context of parenteral vaccination represents a new paradigm of medical practice; the use of a low cost intervention to prevent an event of very low prevalence but of significant cost.

    A severe fungal infection affecting the head and lateral line system was diagnosed in 7 captive scalloped hammerhead sharks Sphyrna lewini in an aquarium in Thailand. Extensive and severe necrotizing cellulitis was consistently observed microscopically along the cephalic and lateral line canals in conjunction with positive fungal cultures for Fusarium sp. Molecular phylogenetic analysis was performed from 3 isolates based on the nucleotide sequences containing internally transcribed spacer (ITS) and a portion of 5.8S and 28S rDNA. The fungus was highly homologous (100%) and closely related to F. solani species complex 2 (FSSC 2), which belongs to Clade 3 of the FSSC. Our results illustrate the histopathological findings and expand upon our knowledge of the prevalence of invasive fusariosis in the head and lateral line system of hammerhead sharks. PMID:27503915

    Vassoille, R.; Perez, J.

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

    We report the case of a long-lasting cutaneous side effect after inappropriate use of Octenisept® solution (containing octenidine and phenoxyethanol). Following lavage of an abscess in the inguinal region, a painful erythematous induration mimicking cellulitis persisted for several months. Manual lymphatic drainage considerably improved the symptoms. Octenisept® shows considerable tissue toxicity in vivo including - but not restricted to - blood vessel damage. Deterioration of endothelial cells followed by oedema and continued tissue damage can be seen histologically. Despite the fact that there is a circular letter issued by the manufacturer as well as a boxed warning on the bottles, the awareness to avoid this misuse of Octenisept® is still lacking.

    We compared the activities of tedizolid to those of linezolid and other commonly used antimicrobial agents against gram-positive cocci recovered from patients with skin and skin structure infections (SSSIs) and hospital-acquired pneumonia (HAP) in Korean hospitals. Gram-positive isolates were collected from 356 patients with SSSIs and 144 patients with HAP at eight hospitals in Korea from 2011 to 2014. SSSIs included impetigo, cellulitis, erysipelas, furuncles, abscesses, and infected burns. Antimicrobial susceptibility was tested by using the CLSI agar dilution method. All of the gram-positive isolates were inhibited by ≤1 μg/mL tedizolid. The minimum inhibitory concentration [MIC]₉₀ of tedizolid was 0.5 μg/mL for methicillin-resistant Staphylococcus aureus, which was 4-fold lower than that of linezolid. Tedizolid may become a useful option for the treatment of SSSIs and HAP caused by gram-positive bacteria.

    Althought serious illnesses can be transmitted by mosquitoes, the most frequent manifestations are due to the contact with saliva of mosquitoes during the blood meal. Culex and Aedes are meeting in countries with moderate climates. Clinical signs vary according to the immunoallergical response, from simple pruritic wheals to immediate and/or delayed allergic reactions. Some reactions can provoke confusion with an infectious cellulitis and an inappropriate antibiotherapy. The natural history of insect bite reactions in an individual tends to progress through 5 stages until immunizing tolerance settles down. Skin prick testing or Serum specific IgE of whole body extracts are lacking sensibility and specificity. Actually, they must be reserved for the most invalidating or severe cases. The recombinant allergens of the saliva of mosquitoes should allow to improve diagnosis and to envisage immunotherapy.

    Scorpion sting is one of the common paediatric toxicological problems encountered in southern India. This rural emergency often results in an autonomic storm causing peripheral circulatory failure and/or congestive cardiac failure, leading to pulmonary oedema. A rare case of scorpion sting envenoming in an 11-year-old boy that led to local cellulitis, dyspnoea and congestive heart failure is presented. This was followed by a persistent high-grade fever which lasted for more than 2 weeks and was complicated by fatal Staphylococcus aureus infective endocarditis and septic pulmonary embolism. Although infective endocarditis has been reported occasionally in adults following scorpion sting, this is the first case of infective endocarditis in a native valve in a child following scorpion sting. The literature is reviewed and the mechanisms for this association are discussed.

    Owing to technical advances and improvement of the software, diffusion weighted imaging and diffusion tensor imaging (DWI and DTI) greatly improved the diagnostic value of magnetic resonance imaging (MRI) of the pelvic region. These imaging sequences can exhibit important tissue contrast on the basis of random diffusion (Brownian motion) of water molecules in tissues. Quantitative measurements can be done with DWI and DTI by apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values respectively. ADC and FA values may be changed by various physiological and pathological conditions providing additional information to conventional MRI. The quantitative DWI assists significantly in the differentiation of benign and malignant lesions. It can demonstrate the microstructural architecture and celluler density of the normal and diseased uterine zones. On the other hand, DWI and DTI are useful for monitoring the treatment outcome of the uterine lesions. In this review, we discussed advantages of DWI and DTI of the normal and diseased uterus.

    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.

    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

This system, controlled by a microcomputer, gives the sheet resistance, the density and the mobility of the sample free carriers with the same accuracy as with the van der Pauw method. The 3× 3 mm sample is pressed straight on the cell without any previous technological process. We deal with the determination of the two apparatus factors from a simple calibration procedure made only once. At last, we give results concerning GaAs superficial or buried layers. Dans cet article, nous proposons une technique de caractérisation non destructive de couches semiconductrices qui utilise une cellule hyperfréquence originale permettant des mesures d'effet Hall.

L'échantillon de 3× 3 mm est appliqué directement sur la cellule, sans subir l'opérations technologiques préalables. Nous détaillons le procédé de détermination des deux coefficients d'appareil obtenus à partir d'un étalonnage très simple effectué une fois pour toutes.

  12. Cofactor recycling mechanism in asymmetric biocatalytic reduction of carbonyl compounds mediated by yeast: which is the efficient electron donor?

    PubMed

    2003-08-01

    In asymmetric reduction of carbonyl compounds mediated by microorganisms, the cofactors that transfer hydride should be regenerated by using a recycling system. In most cases, this recycling system consists of carbohydrate molecules, especially glucose or sucrose. Other molecules such as ethanol and acetate have been used as electron donors too. The reduction can even be conducted without added electron donors. To improve biocatalytic synthesis, it is important to understand the cofactor recycling mechanism. In this work, the hydride-transfer mechanism in cofactor regeneration, which takes place in bioreduction mediated by yeast, was studied by means of an isotope tracing technique. The results show that, when glucose was used, the NADH involved in the glycolysis was consumed directly in the formation of ethanol and was not used in the bioreduction. Hence, the regeneration of cofactors in the reduction is not coupled with glycolysis. Nevertheless, glucose is an efficient electron donor that transfers hydride through the hexose monophosphate (HMP) pathway in which the main hydrogen source is C-1 and C-3 hydrogen of glucose. Ethanol is not a good electron donor, since, when it was used, only a small quantity of hydrogen was transferred from this molecule, and the main hydrogen source was water. Therefore, the ethanol oxidation pathway may not be efficient. In the absence of added auxiliary substrates, the yeast cells may use electron donors stored in its cellules. However, in this case we observed that the main hydrogen source for cofactor recycling was water, while only very few hydrogen atoms were from unexchangeable sites. This is similar to the case in which ethanol is used, and is in contradiction with the HMP pathway if stored glucose was the electron donor. The question that remains to be investigated is "what is the efficient electron donor recycling mechanism in the yeast cellules?" PMID:12898687

    2010-01-01

    Background Diabetic foot infections are common, serious, and varied. Diagnostic and treatment strategies are correspondingly diverse. It is unclear how patients are managed in actual practice and how outcomes might be improved. Clarification will require study of large numbers of patients, such as are available in medical databases. We have developed and evaluated a system for identifying and classifying diabetic foot infections that can be used for this purpose. Methods We used the (VA) Diabetes Epidemiology Cohorts (DEpiC) database to conduct a retrospective observational study of patients with diabetic foot infections. DEpiC contains computerized VA and Medicare patient-level data for patients with diabetes since 1998. We determined which ICD-9-CM codes served to identify patients with different types of diabetic foot infections and ranked them in declining order of severity: Gangrene, Osteomyelitis, Ulcer, Foot cellulitis/abscess, Toe cellulitis/abscess, Paronychia. We evaluated our classification by examining its relationship to patient characteristics, diagnostic procedures, treatments given, and medical outcomes. Results There were 61,007 patients with foot infections, of which 42,063 were classifiable into one of our predefined groups. The different types of infection were related to expected patient characteristics, diagnostic procedures, treatments, and outcomes. Our severity ranking showed a monotonic relationship to hospital length of stay, amputation rate, transition to long-term care, and mortality. Conclusions We have developed a classification system for patients with diabetic foot infections that is expressly designed for use with large, computerized, ICD-9-CM coded administrative medical databases. It provides a framework that can be used to conduct observational studies of large numbers of patients in order to examine treatment variation and patient outcomes, including the effect of new management strategies, implementation of practice guidelines

    Background Beyond their lipid-lowering abilities, statins have anti-inflammatory and immunomodulatory properties. In view of these effects, a growing interest has emerged in the possible role of statins, in preventing or decreasing morbidity and mortality from infection. Objectives The aim of this study was to determine whether previous statin use is associated with reduced risk of acute bacterial infections and better outcome of these infections. Materials and Methods In this historical cohort study, consecutive adult patients admitted with acute bacterial infection were enrolled. Control group were selected from adult outpatient and without history of acute bacterial infections. Acute bacterial infections included in this study were; pneumonia, acute pyelonephritis, cellulitis and sepsis with unknown origin. Data about baseline characteristics, co-morbidities and statins use of two groups was obtained. Results Finally 144 patients met inclusion criteria and were enrolled. Same numbers of controls were selected. Two groups were matched based on most baseline characteristics and co-morbidities. The patients’ categories were as follows: pneumonia 42.3%, acute pyelonephritis 23.6%, cellulitis 16% and sepsis 18%. From all participants 29.9% of patients and 45.8% controls were statin users. There was significant association between previous statin use and reduced risk of acute bacterial infections (Mantel Haenszel Weighted Odds Ratio=0.51, 95% CI: 0.30-0.85, p=0.009). Duration of hospitalization was significantly shorter in statin users (p=0.002). Hospital mortality rate was lower (14.6%) in statins users when compared with non-users (18.8%) with significant difference (p=0.028). Conclusion Prior therapy with statins is associated with considerably reduced onset of acute bacterial infections and better outcome in adult patients. PMID:26676277

    Background: The primary cicatricial alopecias (PCAs) are a rare group of diseases where hair follicle is the primary target of destruction. There are a few studies on histopathological and trichoscopic features of PCA. Aims: To study the clinical, trichoscopic, and histopathological characteristics of PCAs of the scalp and to find out the concordance between trichoscopic and histopathological diagnosis. Materials and Methods: We retrospectively analyzed the clinical, trichoscopic, and histopathological features of 24 PCA patients. Fisher's Chi-square exact test was done to find the significant trichoscopic and histopathological features. Cohen's kappa coefficient was used to determine the agreement between histopathological and trichoscopic diagnosis. Results: A total of 24 patients of PCA were seen with a male: female ratio of 2:1. There were 10 (41.7%) patients of discoid lupus erythematosus (DLE), 5 (20.8%) of lichen planopilaris (LPP), 3 (12.5%) of dissecting cellulitis of scalp, and 2 (8.3%) each of pseudopelade of brocq, folliculitis decalvans, and frontal fibrosing alopecia. The important histopathological findings of DLE were follicular plugging, vacuolar changes in the basal layer, necrotic keratinocytes, and superficial and deep perifollicular and perivascular lymphocytic infiltrate. Histopathology of LPP showed vacuolar changes in the basal layer and lichenoid infiltrate involving the infundibulum and isthmus. Trichoscopy of DLE showed follicular plugging, yellow dots, and thick arborizing blood vessels. The peripilar cast was important finding in LPP. The characteristic yellow dot with three-dimensional structure was noted in dissecting cellulitis of the scalp. The Cohen's kappa agreement was 0.89 between histopathological and trichoscopic diagnosis. Conclusion: The diagnosis of PCA is challenging because of overlapping features clinically and histopathologically. Trichoscopy may provide quick and reliable diagnosis and obviate the necessity of scalp

    Perioperative infection is the most common and dreaded complication associated with tissue expander (TE) breast reconstruction. Historically, the expansion period was thought to be the time of greatest hazard to the implant. However, recent institutional observations suggest infectious complications occur prior to expansion. This investigation, therefore, was conducted to determine the timing of infectious complications associated with two-stage TE breast reconstructions. Following IRB approval, a retrospective review of all consecutive two-stage immediate TE breast reconstructions at a single institution from November 2007 to November 2011 was conducted. Reconstructions were then divided into two cohorts: those suffering infectious complications and those that did not. Infectious complications including minor cellulitis, major cellulitis, abscess drainage, and explantation were identified. Various operative and patient variables were evaluated in comparison. Eight hundred ninety immediate two-stage TE breast reconstructions met inclusion criteria. Patients suffering infection were older (55.4 years versus 49.3 years; p < 0.001), and more likely to have therapeutic mastectomy (94% versus 61%; p < 0.0001), the use of acellular dermal matrix (ADM; 72.5% versus 54.9%; p = 0.001), and greater initial TE fill (448.6 mL versus 404.7 mL; p = 0.0078). The average time to developing of infectious symptoms was 29.6 days (range 9-142 days), with 94.6% (n = 87) of infections prior to the start of expansion. Perioperative infections in immediate two-stage TE to implant breast reconstructions are significant and occur mostly prior to the start of expansion. Thus, challenging the conventional wisdom that instrumentation during expander filling as the primary cause of implant infections. Possible etiologic factors include greater age, therapeutic mastectomy versus prophylactic mastectomy, larger initial TE fill, and the use of ADM.

  18. Wound infections on board ship--prevention, pathogens, and treatment.

    Wounds are common in seafarers and they can easily become infected in the marine environment. Pre-sea tetanus immunization is essential. Without diagnostic facilities and only a limited range of antibiotics onboard, injury prevention and early treatment to reduce the likelihood of infection are important measures. Suturing clean cuts reduces healing time and risk of infection. Fresh, clean cuts, especially on the face or head, can be closed by adhesive tape or sutures, but if infection arises, then one or more sutures should be removed to enable drainage. Most wounds must be considered contaminated and should not be closed, just covered with sterile dressing after cleaning. Antibiotic treatment should be started immediately in seafarers with hand and puncture wounds. The primary treatment for a simple abscess is incision and drainage. Antibiotic treatment is recommended for abscesses if the infection spreads to the surrounding tissue (associated cellulitis), if there is lack of response to incision and drainage alone, or if the abscess is in an area difficult or dangerous to drain (e.g. face, palm, genitalia). Recommended therapy for cellulitis is 5-10 days of dicloxacillin, cephalexin, clindamycin, or erythromycin, but if there is no improvement after 2-3 days, methicillin-resistant Staphylococcus aureus (MRSA) should be suspected. Bites and burn wounds require special attention. Since wound infections can deteriorate rapidly, a telemedicine advice service (TMAS) should be consulted during the early stages, and serial digital photographs of the affected area, transmitted by e-mail to TMAS, are often useful during treatment at sea.

    Nowadays, in industrialised societies, it is fashionable for women to be slim. However, throughout history, this has not always been the case, especially as "cellulite" (cellulitis) was full of typically feminine symbols. The ideal feminine silhouette has changed with the rhythm of cultures. Cellulitis is an inappropriate term used by women to describe curves which they judge to be too plump and not very aesthetic, mostly around the thighs and hips. This lipodystrophy of the adipose tissue represents approximately 25% of a woman's body weight. It is clinically characterised by an "orange peel" skin surface, which is a result of the excessive development of the volume of the adipocytes organised in lobules within the walls of the unstretchable conjunctive tissue. This phenomenon is associated with an insufficiency of the venous tonus and an increase in the capillary permeability, which both contribute to an increase in the infiltration of water in the tissue. In reality, the understanding of cellulite has truly progressed with research based on adipocyte functions. An adipocyte is a metabolically active cell which plays a central role in the control of the energetic balance of the organism. In order to assume this role, it possesses all the enzymatic equipment necessary for synthesis (lipogenesis) and for triglyceride storage, mobilisation and liberation as free fatty acids (lipolysis). During these last few years, as well as this role as an energetic reserve which manages lipogenesis/lipolysis balance, the adipocyte has acquired the status of an endocrine and paracrine cell through the identification of numerous secreted factors. When we look back at the history of slimming products launched on the market since the 1980's, we can notice the role of the adipocyte tool and understand its functions in the choice of active ingredients, the development of complementary actions, the importance of the texture, the evolution of methods used to evaluate the efficacy on

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

    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.

    OBJECTIVE: The authors reviewed patients who developed sepsis or soft tissue infections caused by marine Vibrio bacteria in Florida. SUMMARY BACKGROUND DATA: Marine Vibrio bacteria are the most common bacteria found in seawater. They are concentrated in marine animals that feed by filtration such as oysters and clams. These bacteria can cause gastroenteritis, sepsis, cellulitis leading to necrotizing soft tissue infection after exposure to seawater or consumption of raw seafood. METHODS: The authors received 182 systemic infections that occurred in Florida between January 1, 1979, and December 31, 1991, which were treated by the authors or were reported to the Florida Department of Health and Rehabilitative Services. Patients were divided into two groups depending on whether they presented with primary bacteremia or soft tissue infection. RESULTS: Seventy-one patients had been exposed to these bacteria by eating raw seafood, 94 had direct exposure to seawater, and exposure was uncertain in 27 patients. Vibrio species were cultured from the blood of 103 patients and from wounds or soft tissues of 113. An additional 5 patients had cellulitis but bacteria were not cultured from these sites. In patients in whom it could be determined, 93 had primary soft tissue infections and 82 had primary bacteremia. Twenty-four patients had necrotizing soft tissue infections and required surgical debridement. Three of these 24 patients required amputation. Thirty-seven (20.3%) patients died. Severe liver disease occurred in 54 patients and 25 of these patients died. CONCLUSIONS: Marine Vibrio bacteria can cause sepsis and soft tissue infections, especially in individuals with severe liver disease and other chronic illnesses such as diabetes mellitus. The authors believe all individuals, especially those with systemic illness, should be warned against eating raw seafood. Images Figure 1. PMID:8489315

    Speciation studies consist in the determination of the molecular characteristics of the elements. The research currently carried out in that field is aimed at describing the intracellular deposit of the radionuclides and the complexation mechanisms which determine their behaviour. Such studies are developed in order to contribute towards the solution of two major problems in the field of internal dosimetry: the realistic assessment of the dose received by the target cells and the therapeutic removal of neptunium or uranium after internal contamination. The work presented thereafter resumes the main results obtained in that field. La spéciation est l',étude des caract,ristiques moléculaires des ,éléments radioactifs.

    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

    2012-01-01

    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

    La laparoscopia rappresenta un approccio ormai noto per trattare chirurgicamente le patologie benigne e maligne colorettali e numerosi autori hanno riportato una risposta immunologica migliore nei pazienti sottoposti a chirurgia laparoscopica eseguendo un confronto con la chirurgia colorettale tradizionale. Il trauma chirurgico determina una risposta immunitaria locale che può diventare una risposta sistemica in seguito agli stimoli infiammatori e ciò porta ad attivazione del sistema immunitario in difesa dal trauma chirurgico e contemporaneamente una modulazione negativa con immunosoppressione circa l’eventuale difesa dalle infezioni e la diffusione di cellule neoplastiche. Lo scopo del nostro studio è valutare la differente risposta bioumorale al trauma chirurgico in pazienti sottoposti a resezione colica per via videolaparoscopica ed in pazienti sottoposti ad analogo intervento per via laparotomica convenzionale. Sono stati arruolati quattordici pazienti, con patologia maligna colorettale, di cui 7 sottoposti a chirurgia laparoscopica e 7 a chirurgia tradizionale, selezionati in base all’anamnesi negativa per pregressa patologia neoplastica e/o per patologie particolarmente invalidanti ed in base alla stadiazione del tumore, per cui non vi era evidenza di metastasi a distanza. Tutti i campioni sono stati collezionati prima dell’intervento e dopo di esso, alle 24 ore e a 7 giorni e sottoposti ad analisi di laboratorio: analisi ELISA, determinazione PCR tramite dosaggio immunoturbidimetrico quantitativo, fenotipizzazione delle cellule immunitarie. Abbiamo osservato un incremento significativo dei livelli circolanti di Proteina CReattiva (PCR) alle 24h dall’intervento nel gruppo convenzionale. Il valore dell’Interleuchina-6 (IL-6) ha subito un aumento nell’immediato postoperatorio dopo approccio laparoscopico. I livelli delle sottopopolazioni linfocitarie subiscono minor elevazione nel gruppo laparoscopico. In conclusione, la produzione di mediatori

    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].

    Little is known about the relative importance of the four species of Lancefield group G beta-hemolytic streptococci in causing bacteremia and the factors that determine the outcome for patients with group G beta-hemolytic streptococcal bacteremia. From 1997 to 2000, 75 group G beta-hemolytic streptococcal strains were isolated from the blood cultures of 66 patients. Sequencing of the 16S rRNA genes of the group G beta-hemolytic streptococci showed that all 75 isolates were Streptococcus dysgalactiae subspecies equisimilis. The API system (20 STREP) and Vitek system (GPI) successfully identified 65 (98.5%) and 62 (93.9%) isolates, respectively, as S. dysgalactiae subspecies equisimilis with >95% confidence, whereas the ATB Expression system (ID32 STREP) only successfully identified 49 isolates (74.2%) as S. dysgalactiae subspecies equisimilis with >95% confidence. The median age of the patients was 76 years (range, 33 to 99 years). Fifty-six patients (85%) were over 60 years old. All patients had underlying diseases. No source of the bacteremia was identified (primary bacteremia) in 34 patients (52%), whereas 17 (26%) had cellulitis and 8 (12%) had bed sore or wound infections. Fifty-eight patients (88%) had community-acquired group G streptococcal bacteremia. Sixty-two patients (94%) had group G Streptococcus recovered in one blood culture, whereas 4 patients (6%) had it recovered in multiple blood cultures. Fifty-nine patients (89%) had group G Streptococcus as the only bacterium recovered in their blood cultures, whereas in 7 patients other bacteria were recovered concomitantly with the group G Streptococcus in the blood cultures (Staphylococcus aureus in 3, Clostridium perfringens in 2, Citrobacter freundii in 1, and Bacteroides fragilis in 1). Overall, 10 patients (15%) died. Male sex, diagnosis other than cellulitis, hospital-acquired bacteremia, and multiple positive blood cultures were associated with mortality {P < 0.005 (relative risk [RR] = 7.6), P < 0

    Les tumeurs brunes sont des lésions ostéolytiques rarement révélatrices des hyperparathyroïdies. Elles surviennent habituellement au stade terminal de l'hyperparathyroïdie primaire ou secondaire. Durant les 3 dernières décennies, le diagnostic des hyperparathyroïdies est le plus souvent fait à la phase asymptomatique grâce aux dosages systématiques du calcium et l'avènement des nouvelles techniques, de dosage de la parathormone. Nous rapportons l'observation d'une patiente avec hyperparathyroïdie primaire révélée par une tumeur du maxillaire, dont la TDM avait mis en évidence un processus ostéolytique agressif. L'intervention chirurgicale a consisté en une maxillectomie droite avec reconstruction. Le résultat anatomo-pathologique a conclu en une tumeur à cellule géantes bénigne du maxillaire. Le diagnostic de tumeur brune a été évoqué et confirmé après la réalisation d'un bilan phosphocalcique qui a mis en évidence une hypercalcémie, avec une hypophosphorémie. La recherche étiologique a objectivé à la TDM cervicale un processus en situation rétro et infra thyroïdienne droite en faveur d'un adénome parathyroïdien. Le dosage de la parathormone: 322 pmol/L a confirmé le diagnostic. Nous rappelons à travers cette observation la difficulté d’établir un diagnostic correct chez les patients avec un processus ostéolytique du maxillaire et la nécessité de rechercher une hyperparathyroïdie devant une lésion à cellules géantes vue le caractère insidieux de cette endocrinopathie.

    Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease with high mortality. Many disorders can mimic CCHF. It is important to recognize the condition and to perform differential diagnosis in endemic countries. Twenty-one children aged 18 years or less with a preliminary diagnosis of CCHF were retrospectively evaluated. Real-time PCR and a confirmatory indirect immunofluorescence assay for negative results were performed. The diagnoses determined that 9 patients had (42.9%) CCHF; 7 patients had (33.3%) viral upper respiratory tract infections (URTI); 2 patients had (9.5%) brucellosis; 1 patients had (4.7%) periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome episode; 1 patient had (4.7%) cerebral palsy, diabetes insipidus, acute gastroenteritis, and hypernatremic dehydration; and 1 patient had (4.7%) cellulitis after a tick bite. The mean age of patients with CCHF was greater than that of the other patients (116.1±53.6 vs. 94.1±52.1 months, p=0.02). Seventeen (81%) of the children included had a history of tick bites, 2 (9.5%) had a history of contact with a patient with CCHF, and 2 (9.5%) had no exposure, but were living in an endemic region. Three patients had an underlying disorder: cerebral palsy and diabetes insipidus, epilepsy, or PFAPA. All of the children experienced fever. Other frequent symptoms were malaise, diarrhea, vomiting, and abdominal pain, but none of these differed statistically between the patient groups. CCHF patients had a longer mean duration of symptoms (10.56±1.42 vs. 6.75±3.62 days, p=0.008) and a longer mean length of hospitalization (8.00±2.08 vs. 3.58±1.56 days, p<0.001) than the other patients. At laboratory examination, patients with CCHF had statistically significant lower leukocyte and platelet counts, more prolonged coagulation parameters, and greater AST, ALT, LDH, and CK levels than the other patients. No mortality or complications occurred in the study. Both infectious causes, such as

    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.

    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].

    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

    Extracts of some spices have been reported to play a contributory role in enhancing immune function. We evaluated and compared the effect(s) of single and combined oral administration of fresh aqueous onion (Allium cepa) and garlic (Allium sativum) extracts at different concentrations on some immunological determinants in rats. CD₄ cells of the rats were estimated using Partec flow cytometric technique, while total and differential white blood cell (WBC) counts were estimated using the Sysmsex® automated haematology analyzing technique. Our findings revealed that, CD4 and total WBC counts were significantly increased (P≤0.05) in a dose-dependent manner in both onion (250mg/Kg/d: 349±11cell/ul and 2.75±0.15X10³cell/l; 500mg/Kg/d: 389±10cells/µl and 3.05±0.05 X10³cell/l; 750mg/Kg/d: 600±11cell/µl and 3.25±0.05X10³cells/l) and garlic (250mg/Kg/d: 410±10cell/ul and 2.85±0.15X10³cell/l; 500mg/Kg/d: 494±32cells/µl and 3.30±0.10 X10³cell/l; 750mg/Kg/d: 684±11cell/µl and 3.55±0.05X10³cells/l) treated rats when compared to the zero control (200±11cells/µl and 1.55±0.05X10³cells/l, respectively). Extract of garlic at 750mg/Kg/d had significantly increased the CD4 cells and total white cell count when compared to other concentrations (P≤0.05). However, no significant effect was observed on these parameters when extracts were combined (250mg/Kg/d: 252±21cell/µl and 1.80±0.10X10³cells/l; 500mg/Kg/d: 315±21cells/ul and 2.10±0.10X10³cells/l; 750mg/Kg/d: 368±10cells/µl and 2.35±0.05X10³cells/l, respectively), the differential WBC count showed a significant increase in the proportion of cell types (lymphocytes, neutophils and monocytes) (P≤0.05). The results from this study revealed the immune boosting capabilities of Allium cepa and Allium sativum, but underscored their synergistic activities. PMID:23983369

    Prescription drug abuse ranks as the second most common class of illicit drug use in the United States, and one mechanism of opiate abuse involves intravenous injection of enteral narcotics such as oxycodone or hydrocodone. The authors describe a patient who sustained significant soft tissue necrosis after intravenously injecting a solution made from crushed enteral narcotics, with a focus on the operative course that resulted due to a delay in initial definitive treatment. The patient's wounds encompassed 8% total body surface area and covered 247 cm2. A 55-year-old female was admitted to the burn unit (West Penn Burn Center, Western Pennsylvania Hospital, Pittsburgh, PA) after she initially presented with infection and cellulitis to her bilateral upper extremities 3 weeks after intravenously injecting herself with crushed oxycodone/acetaminophen. She underwent numerous sequential operative repairs including initial debridement, placement of dermal replacement templates, and several split-thickness autografts and xenografts. Her total length of stay was 59 days, broken into an initial 47-day stay, and a subsequent 12-day readmission due to graft failure secondary to poor follow-up. As the number of prescription drug abusers rises, it is possible that an increase in attempts to intravenously abuse enteral narcotics may also rise. As such, burn centers should be prepared for the extent of potential limb necrosis and the operative treatment that may ensue.

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

    Helicobacter cinaedi causes infections, such as bacteremia, diarrhea and cellulitis in mainly immunocompromised patients. This pathogen is often problematic to analyze, and insufficient information is available, because it grows slowly and poorly in subculture under a microaerobic atmosphere. The first-choice therapy to eradicate H. cinaedi is antimicrobial chemotherapy; however, its use is linked to the development of resistance. Although we need to understand the antimicrobial resistance mechanisms of H. cinaedi, unfortunately, sufficient genetic tools for H. cinaedi have not yet been developed. In July 2012, the complete sequence of H. cinaedi strain PAGU 611, isolated from a case of human bacteremia, was announced. This strain possesses multidrug efflux systems, intrinsic antimicrobial resistance mechanisms and typical mutations in gyrA and the 23S rRNA gene, which are involved in acquired resistance to fluoroquinolones and macrolides, respectively. Here, we compare the organization and properties of the efflux systems of H. cinaedi with the multidrug efflux systems identified in other bacteria. PMID:27029418

    A 46-year-old man who had been treated with azathioprine and budesonide for Crohn's disease for the past eight years developed a purulent skin condition on the right ring finger. Despite surgical drainage and treatment with amoxicillin and flucloxacillin, the condition spread itself over the hand and lower arm, partly per continuum and partly in jumps. The patient did not feel ill and there were no systemic symptoms. Ultimately, Nocardia asteroides was cultured from the wound and complete cure was achieved after 8 months' treatment with co-trimoxazole. Infections with Nocardia spp. are rare but may occur more often and run a more fulminant course in patients under treatment with immunosuppressants. Cutaneous nocardiosis generally has a characteristic lymphogenous spreading pattern, but an atypical picture with pustules, pyoderma, cellulitis or abscess formation is also possible. In non-cutaneous nocardiosis there is usually pneumonia or lung abscess, possibly with secondary haematogenous spread to the central nervous system or skin. Culturing Nocardia requires more time than usual but can be promoted by special culture media. Treatment of the infection with co-trimoxazole is the method of choice and is almost always successful in cases of cutaneous nocardiosis.

    The composition of human skin acts as a natural habitat for various bacterial species that function in a commensal and symbiotic fashion. In a healthy individual, bacterial flora serves to protect the host. Under certain conditions such as minor trauma, impaired host immunity, or environmental factors, the risk of developing skin infections is increased. Although a large majority of bacterial associated skin infections are common, a portion can potentially manifest into clinically significant morbidity. For example, Gram-positive species that typically reside on the skin such as Staphylococcus and Streptococcus can cause numerous epidermal (impetigo, ecthyma) and dermal (cellulitis, necrotizing fasciitis, erysipelas) skin infections. Moreover, the increasing incidence of bacterial antibiotic resistance represents a serious challenge to modern medicine and threatens the health care system. Therefore, it is critical to develop tools and strategies that can allow us to better elucidate the nature and mechanism of bacterial virulence. To this end, mass spectrometry (MS)-based proteomics has been revolutionizing biomedical research, and has positively impacted the microbiology field. Advances in MS technologies have paved the way for numerous bacterial proteomes and their respective post translational modifications (PTMs) to be accurately identified and quantified in a high throughput and robust fashion. This technological platform offers critical information with regards to signal transduction, adherence, and microbial-host interactions associated with bacterial pathogenesis. This mini-review serves to highlight the current progress proteomics has contributed toward the understanding of bacteria that are associated with skin related diseases, infections, and antibiotic resistance.

    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

    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

    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.

    Four kinds of TiO2 electrodes with different porosities were prepared by adding different ratios of ethyl cellulous into a Dyesol 18-NRT paste. Higher polymer ratios contributed to the higher porosity of TiO2 films. All electrodes were spin-coated with spiro-OMeTAD and fabricated into solid-state dye-sensitized solar cells (ss-DSCs). This simple method allowed more spiro-OMeTAD penetrated into the more porous TiO2 films. This result demonstrated the pore-filling effect of hole transport materials on the photovoltaic performance of ss-DSCs. Photoluminescence and electrical impedance spectra measurements were introduced to investigate the dye regeneration, charge transport, and recombination kinetics of the solar cells. The increased pore filling of spiro-OMeTAD could enhance hole injection, hole transport, and recombination retardation, thus providing good charge collection efficiency and long recombination lifetime and resulting in the high short-circuit current density, open-circuit voltage, fill factor, and energy conversion efficiency of the solar cells. An efficiency enhancement of 34 % was obtained by using this method. However, further increasing the TiO2 porosity decreased the electron transport, thus causing a low charge collection and reducing cell performance.

    In order to assess the clinical characteristics and impact of group A streptococcal infection in children with atopic dermatitis, a retrospective review was performed in children diagnosed with atopic dermatitis who had a skin culture. Culture results and clinical characteristics of those with group A streptococcus were compared with those with Staphlococcus aureus. Infection with group A streptococcus was present in 16%; infection with Staphlococcus aureus was present in 72%, and 14% had mixed cultures. Patients infected with group A streptococcus were more likely to be febrile, to have facial and periorbital involvement, and to be hospitalized compared with those infected with Staphlococcus aureus alone (p ≤ 0.01 for all comparisons). Bacteremia and cellulitis were significantly more common in those infected with group A streptococcus than in those infected with Staphlococcus aureus. Retrospective design and review of only those patients receiving bacterial cultures may select for greater severity than in the general atopic dermatitis population. Group A streptococcus appears to be a significant skin pathogen infecting children with atopic dermatitis. Children with atopic dermatitis and group A streptococcal infection are more likely to have invasive disease and complications than those infected with Staphlococcus aureus alone.

    Here we describe the successful surgical implementation of antibiotic-impregnated polymethylmethacrylate beads in a rhesus macaque (Macaca mulatta) with marked osteomyelitis. The macaque presented to the veterinary clinic with grossly contaminated bite wounds in the left ankle secondary to conspecific trauma. Radiographic findings were highly suggestive of osteomyelitis. Additional differential diagnoses included bony infarct, fracture, and cellulitis. In light of the location of the lesion and extensive tissue trauma, the animal had a poor prognosis. Systemic, broad-spectrum antibiotics were instituted. After 2 wk of care, lesions did not respond to empirical therapies. On consultation, a veterinary orthopedic surgeon at another facility recommended placement of antibiotic-impregnated polymethylmethacrylate beads at the sites of osteomyelitis. The animal underwent minor surgery in which beads were introduced into the wound. The monkey had a positive response to therapy. The animal regained full function and was returned to outdoor social housing. Veterinarians are encouraged to consider using antibiotic-impregnated polymethylmethacrylate beads when treating osteomyelitis in other nonhuman primates and in other traditional laboratory animal species.

    We compared results using unidirectional barbed sutures and conventional sutures for vaginal cuff closure during total laparoscopic hysterectomy (TLH).The electronic medical records and surgical videos of 170 patients who underwent TLH between January 2013 and March 2015 at Uijeong-bu St. Mary's Hospital of Catholic University of Korea were reviewed. Vaginal cuffs were closed using the 2-layer continuous running technique with unidirectional barbed sutures (V-Loc; Covidien, Mansfield, MA) in 64 patients and with polycolic acid Vicryl; Ethicon, Somerville, NJ sutures in 106 patients. Procedure time, clinical characteristics, and postoperative complications were compared between the 2 study groups. There were no differences in clinical characteristics (age, body mass index, and demographic data) between groups. The mean suturing time was significantly reduced in the barbed group (7.2 vs 12.2 minutes; P < 0.001), although the mean number of stitches was greater than in the Vicryl group (14.1 vs 12.3, P < 0.001). Perioperative complications, including episodes of vaginal bleeding, vaginal cuff cellulitis, and postoperative fever, did not differ between groups. There were no instances of vaginal cuff dehiscence in either group. Unidirectional barbed sutures can be used safely to reduce procedure time and surgical difficulty relative to conventional sutures in laparoscopic vaginal cuff closure. PMID:27684850

    BACKGROUND: Inadvertent intra-arterial injection of illicit substances is a known complication of injection drug use and can lead to severe complications, including infection, ischemia and compartment syndrome. Identifying complications of intra-arterial injection can be difficult, as clinical manifestations overlap with other more common conditions such as cellulitis and soft tissue infection, and a history of injection drug use is frequently not disclosed. METHODS: A 37-year-old male patient presented with 24 hours of right hand pain, erythema and swelling. Despite classic “track marks”, he denied a history of injection drug use, and vascular insults were not initially considered. After failing to respond to three days of aggressive treatment for suspected deep-space infection, an arteriogram demonstrated findings consistent with digital ischemia of embolic etiology. RESULTS: As a result of the delay in diagnosis, the lesion was not amenable to reperfusion and the patient required amputation of the distal digit. CONCLUSION: Practitioners should be alert to the possibility of intra-arterial injection and resulting complications when evaluating unusual extremity infections or unexplained ischemic symptoms, even in the absence of a definite history of injection drug use.

    Drug-induced hepatotoxicity most commonly manifests as an acute hepatitis syndrome and remains the leading cause of drug-induced death/mortality and the primary reason for withdrawal of drugs from the pharmaceutical market. We report a case of acute liver injury in a 12-year-old Hispanic boy, who received a series of five antibiotics (amoxicillin, ceftriaxone, vancomycin, ampicillin/sulbactam, and clindamycin) for cervical lymphadenitis/retropharyngeal cellulitis. Histopathology of the liver biopsy specimen revealed acute cholestatic hepatitis. All known causes of acute liver injury were appropriately excluded and (only) drug-induced liver injury was left as a cause of his cholestasis. Liver-specific causality assessment scales such as Council for the International Organization of Medical Sciences/Roussel Uclaf Causality Assessment Method scoring system (CIOMS/RUCAM), Maria and Victorino scale, and Digestive Disease Week-Japan were applied to seek the most likely offending drug. Although clindamycin is the most likely cause by clinical diagnosis, none of causality assessment scales aid in the diagnosis.

    Background. Outpatient parenteral antibiotic therapy (OPAT) is a safe and effective modality for treating serious infections. This study was undertaken to define the value of OPAT in a multicentered infectious disease (ID) private practice setting. Methods. Over a period of 32 months, 6120 patients were treated using 19 outpatient ID offices in 6 states. Analysis included patient demographics, indications of OPAT, diagnoses, therapeutic agent, duration of therapy, and site of therapy initiation. Outcomes were stratified by therapeutic success, clinical relapse, therapeutic complications, and hospitalizations after initiating therapy. Statistical analysis included an ordinal logistic regression analysis. Results. Forty-three percent of patients initiated therapy in an outpatient office, and 57% began therapy in a hospital. Most common diagnoses treated were bone and joint (32.2%), abscesses (18.8%), cellulitis (18.5%), and urinary tract infection (10.8%). Ninety-four percent of patients were successfully treated, and only 3% were hospitalized after beginning therapy. Most common cause of treatment failure was a relapse of primary infection (60%), progression of primary infection (21%), and therapeutic complication (19%). Conclusions. An ID-supervised OPAT program is safe, efficient, and clinically effective. By maximizing the delivery of outpatient care, OPAT provides a tangible value to hospitals, payers, and patients. This program is a distinctive competency available to ID physicians who offer this service to patients. PMID:27807591

    Streptococcus iniae is a major fish pathogen that can also cause human bacteremia, cellulitis and meningitis. Screening for and identification of protective antigens plays an important role in developing therapies against S. iniae infections. In this study, we indicated that the α-enolase of S. iniae was not only distributed in the cytoplasm and associated to cell walls, but was also secreted to the bacterial cell surface. The functional identity of the purified recombinant α-enolase protein was verified by its ability to catalyze the conversion of 2-phosphoglycerate (2-PGE) to phosphoenolpyruvate (PEP), and both the recombinant and native proteins interacted with human plasminogen. The rabbit anti-rENO serum blockade assay shows that α-enolase participates in S. iniae adhesion to and invasion of BHK-21 cells. In addition, the recombinant α-enolase can confer effective protection against S. iniae infection in mice, which suggests that α-enolase has potential as a vaccine candidate in mammals. We conclude that S. iniae α-enolase is a moonlighting protein that also associates with the bacterial outer surface and functions as a protective antigen in mice.

    We collected β-hemolytic streptococci (1,611 isolates) from patients with invasive streptococcal infections in Japan during April 2010-March 2013. Streptococcus dysgalactiae subsp. equisimilis (SDSE) was most common (n = 693); 99% of patients with SDSE infections were elderly (mean age 75 years, SD ±15 years). We aimed to clarify molecular and epidemiologic characteristics of SDSE isolates and features of patient infections. Bacteremia with no identified focus of origin and cellulitis were the most prevalent manifestations; otherwise, clinical manifestations resembled those of S. pyogenes infections. Clinical manifestations also differed by patient's age. SDSE isolates were classified into 34 emm types; stG6792 was most prevalent (27.1%), followed by stG485 and stG245. Mortality rates did not differ according to emm types. Multilocus sequence typing identified 46 sequence types and 12 novel types. Types possessing macrolide- and quinolone-resistance genes were 18.4% and 2.6%, respectively; none showed β-lactam resistance. Among aging populations, invasive SDSE infections are an increasing risk.

    Necrotizing soft tissue infections are a group of highly lethal infections that typically occur after trauma or surgery. Many individual infectious entities have been described, but they all have similar pathophysiologies, clinical features, and treatment approaches. The essentials of successful treatment include early diagnosis, aggressive surgical debridement, antibiotics, and supportive intensive treatment unit care. The two commonest pitfalls in management are failure of early diagnosis and inadequate surgical debridement. These life-threatening infections are often mistaken for cellulitis or innocent wound infections, and this is responsible for diagnostic delay. Tissue gas is not a universal finding in necrotizing soft tissue infections. This misconception also contributes to diagnostic errors. Incision and drainage is an inappropriate surgical strategy for necrotizing soft tissue infections; excisional debridement is needed. Hyperbaric oxygen therapy may be useful, but it is not as important as aggressive surgical therapy. Despite advances in antibiotic therapy and intensive treatment unit medicine, the mortality of necrotizing soft tissue infections is still high. This article emphasizes common treatment principles for all of these infections, and reviews some of the more important individual necrotizing soft tissue infectious entities.

    Veno-occlusive disease (VOD) is a complication arising from the toxicity of conditioning regimens that have a significant impact on the survival of patients who undergo stem cell transplantation. There are several known risk factors for developing VOD and their assessment before the start of conditioning regimens could improve the quality of care. Equally important are early identification of signs and symptoms ascribable to VOD, rapid diagnosis, and timely adjustment of support therapy and treatment. Nurses have a fundamental role at the stages of assessment and monitoring for signs and symptoms; therefore, they should have documented skills and training. The literature defines nurses' areas of competence in managing VOD, but in the actual clinical practice, this is not so clear. Moreover, there is an intrinsic difficulty in managing VOD due to its rapid and often dramatic evolution, together with a lack of care tools to guide nurses. Through a complex evidence-based process, the Gruppo Italiano per il Trapianto di Midollo Osseo (GITMO), cellule staminali emopoietiche e terapia cellulare nursing board has developed an operational flowchart and a dynamic monitoring tool applicable to haematopoietic stem cell transplantation patients, whether they develop this complication or not.

    Magnetic resonance (MR) imaging has opened new horizons in the diagnosis and treatment of many musculoskeletal diseases of the ankle and foot. It demonstrates abnormalities in the bones and soft tissues before they become evident at other imaging modalities. The exquisite soft-tissue contrast resolution, noninvasive nature, and multiplanar capabilities of MR imaging make it especially valuable for the detection and assessment of a variety of soft-tissue disorders of the ligaments (eg, sprain), tendons (tendinosis, peritendinosis, tenosynovitis, entrapment, rupture, dislocation), and other soft-tissue structures (eg, anterolateral impingement syndrome, sinus tarsi syndrome, compressive neuropathies [eg, tarsal tunnel syndrome, Morton neuroma], synovial disorders). MR imaging has also been shown to be highly sensitive in the detection and staging of a number of musculoskeletal infections including cellulitis, soft-tissue abscesses, and osteomyelitis. In addition, MR imaging is excellent for the early detection and assessment of a number of osseous abnormalities such as bone contusions, stress and insufficiency fractures, osteochondral fractures, osteonecrosis, and transient bone marrow edema. MR imaging is increasingly being recognized as the modality of choice for assessment of pathologic conditions of the ankle and foot.

    The Stewart-Treves syndrome is a rare and deadly entity, which is defined as angiosarcoma arising in the setting of chronic lymphedema. It typically presents in women who develop lymphedema in the upper extremity secondary to axillary lymph node dissection for breast cancer surgery. It is extremely uncommon in the lower extremities as a result of idiopathic chronic lymphedema. Here, we present the case of a 63-year-old female patient with idiopathic chronic lymphedema of the lower extremities having morbid obesity (BMI 82.6) and multiple comorbidities. She developed multiple confluent, hemorrhagic and necrotic elevated purple-black papules in the lower extremities, for which the initial diagnosis was cellulitis. Because there was no improvement with antibiotics, a lower extremity ultrasound and biopsy was performed which showed multiple masses in the left inner upper calf with solid and cystic components. The pathology results of the punch biopsies were consistent with angiosarcoma. Immunohistochemical studies revealed positivity for CD31, FLI-1, and a high Ki-67 proliferation rate. Because of the patient's weight and medical comorbidities, no further extensive diagnostic tests were performed to detect metastatic disease, and because of contraindications, no further medical treatment was provided. The patient subsequently died 1 month after diagnosis. PMID:27099606

    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

    Lower limb lymphedema and an accompanying lymphatic fistula (lymphorrhea) occur as complications after gynecologic surgery to treat cancer. Herein, we report the case of a 68-year-old woman who underwent resection and radiotherapy because of uterine cervical cancer (stage 2a) 20 years previously. Left lower limb and pudendal lymphedema and continuous lymphorrhea developed soon after surgery. Conservative treatment was administered; however, the edema increased, and a pudendal lymphatic fistula and cellulitis developed repeatedly. Lymphovascular anastomosis (LVA) and lymph vessel ligation were performed after preoperative evaluation via lymphoscintigraphy and indocyanine green (ICG) lymphography. A radioisotope injected into the first interdigit pedal region flowed into the pudendal region via the inguinal lymph nodes at preoperative lymphoscintigraphy. Linear patterns were observed up to the half level of the crus, and stardust patterns occurred over the lower abdominal and pudendal regions at ICG lymphography. During surgery, ICG lymphography was also used to identify the site of the fistula. With the patient under local anesthesia, LVA was applied in the half crus and left inguinal regions, followed by ligation and division of lymph vessels flowing into the fistula. The region around the fistula was excised as a 1 × 3-cm tissue block. As of 5 months after surgery, no recurrence of lymphatic fistula or exacerbation of lymphedema has occurred. This case shows the effectiveness of preoperative ICG lymphography and lymphoscintigraphy followed by treatment via lymph vessel ligation and LVA for curative resolution of a lymphatic fistula.

    Epidemiology and clinical characteristics of invasive Group A streptococcal infections (IGASI) are highly variable. Long-term studies are needed to understand the interplay between epidemiology and virulence. In a population-based study of IGASI in Iceland from 1975 to 2012, 288 cases were identified by positive cultures from normally sterile body sites. Charts were reviewed retrospectively and emm-types of viable Streptococcus pyogenes isolates (n=226) determined. Comparing the first and last decade of the study period, IGASI incidence increased from 1.09 to 3.96 cases per 100,000 inhabitants per year. The most common were emm types 1 (25%), 28 (11%) and 89 (11%); emm1 strains were most likely to cause severe infections. Infections in adults were significantly more likely to be severe during the seasonal peak from January to April (risk ratio: 2.36, 95% confidence interval: 1.34–4.15). Significant seasonal variability in severity was noted among patients with diagnosis of sepsis, respiratory infection and cellulitis, with 38% of severe infections in January to April compared with 16% in other months (p<0.01). A seasonal increase in severity of IGASI suggested that generalised seasonal increase in host susceptibility, rather than introduction of more virulent strains may play a role in the pathogenesis of these potentially fatal infections.

    We report the first case of a post-acupuncture soft tissue infection due to Mycobacterium fortuitum. Two months after finishing an acupuncture treatment session, an immunocompetent 23-year-old woman developed cellulitis at the side of the needle insertions and the acid-fast bacillus was isolated from a closed abscess. The patient was successfully treated with a proper drug combination. We review the literature concerning the infection source and the risks for skin and soft tissue infection due to mycobacteria after acupuncture. The infection source in most cases is unknown but is probably associated with the inadequate sterilization of the needles or the puncture site. We show that these infections are not rare but difficult to diagnose. To avoid delays in the definitive diagnosis, infection with mycobacteria should be considered for skin and soft tissue infections, in particular late-onset infections, which are negative for routine bacterial cultures and without a clinical response to antibiotics used for acute pyogenic infections. Bacterial cultures from this lesion should be maintained for at least six weeks before discharged as negative.

    This study investigates the effect of a new short-stretch two-layer compression system in eight patients with common chronic lower-limb conditions in three locations in the UK. Chronic leg ulcers are the most common type of lower-limb ulceration with 70% caused by chronic venous hypertension. An appropriate level of compression is proven to heal chronic venous leg ulcers. The study was only a small sample of patients; however, the underlying conditions included chronic venous eczema, diabetes, sarcoma, cellulitis and mixed-aetiology ulcers. During the study, the UK experienced some of the hottest temperatures in the last 30 years. This had an impact on five patients, who noted an increase in malodour associated with their leg ulcers. CoFlex TLC (Aspen Medical Europe Ltd) foam comfort layer is impregnated with cyclodextrin-a naturally based oligosaccharide known to reduce malodour. The zinc-impregnated foam bandages in this study were viewed very favourably by both patients and staff, particularly those who had chronic venous eczema. PMID:24912834

    The symptoms of Staphylococcal scalded skin syndrome (SSSS) include blistering of skin on superficial layers due to the exfoliative toxins released from Staphylococcus aureus. After the acute exfoliation of skin surface, erythematous cellulitis occurs. The SSSS may be confined to few blisters localized to the infection site and spread to severe exfoliation affecting complete body. The specific antibodies to exotoxins and increased clearence of exotoxins decrease the frequency of SSSS in adults. Immediate medication with parenteral anti-staphylococcal antibiotics is mandatory. Mostly, SSSS are resistant to penicillin. Penicillinase resistant synthetic penicillins such as Nafcillin or Oxacillin are prescribed as emergency treatment medicine. If Methicillin-resistant Staphylococcus aureus (MRSA) is suspected), antibiotics with MRSA coverage (e.g., Vancomycin or Linezolid) are indicated. Clindamycin is considered as drug of choice to stop the production of exotoxin from bacteria ribosome. The use of Ringer solution to to balance the fluid loss, followed by maintainence therapy with an objective to maintain the fluid loss from exfoliation of skin, application of Cotrimoxazole on topical surface are greatlly considered to treat the SSSS. The drugs that reduce renal function are avoided. Through this article, an attempt has been made to focus the source, etiology, mechanism, outbreaks, mechanism, clinical manisfestation, treatment and other detail of SSSS. PMID:27651848

    Because patterns of disease and health care system usage by the homeless constitute a neglected area of research in the medical literature, we undertook a retrospective analysis of inpatient records on medically indigent adults, controlling for housing status, to add to the growing body of research in the area of homeless health care. Data on all 4,243 indigent patients admitted over 2 fiscal years (1985 and 1986) under the county medical services program of San Diego County, California, revealed 5.3% (226) to be homeless. The commonest major diagnostic category among the homeless discharges was "diseases and disorders of the skin, subcutaneous tissue, and breast," constituting 21.2% as compared with only 8.7% of the discharge diagnoses for housed indigent persons. Within this major diagnostic category, the predominant diagnosis-related group was cellulitis, accounting for 12.8% of diagnoses in the homeless and only 4.0% of discharge diagnoses in other medically indigent persons. A homeless housing status was also correlated with a higher percentage of discharges with the major diagnostic category of "substance use and substance-induced organic mental disorders" but was negatively correlated with that of "diseases and disorders of the circulatory system."

    This study examined acute-convalescent changes in diagnostic anti-streptococcal antibodies by the anti-streptolysin O (ASO) and anti-DNAase B (ADAB) tests among patients (n 28) with lymphedema and recurrent erisipela of the lower limb, comparing them with endemic normal control residents (n=25). The study was based in Villa Francisca, an urban focus of Bancroftian filariasis in eastern Santo Domingo, capital of the Dominican Republic. The acute signs and symptoms of erisipela were consistent with a diagnosis of bacterial cellulitis. The ASO test was especially successful at demonstrating a rise in mean titer during convalescence, whereas the ADAB produced about the same frequency of significant increases (0.2 log titer) as did the ASO. When subjects were scored as responders if mounting a minimal titer increase by either test, patients were found more frequently positive than were controls (chi2=5.3, P=0.02). About half (54%) of all patients mounted at least a minimal antibody increase. Filaria-specific IgG4 antibodies were absent from all sera of 20 residents of a nonendemic Dominican mountain town but appeared in about two-thirds of the sampled residents of the endemic barrio. Notably however, levels did not change between the acute phase and convalescence. These findings are consistent with the hypothesis that recurrent streptococcal invasion of the lymphatics may be a significant factor triggering or amplifying lymphedema and elephantiasis in patients with chronic filariasis.

    At the request of the Army Air Corps, an investigation of the pressure distribution over PW-9 wing models was conducted in the atmospheric wind tunnel of the National Advisory Committee for Aeronautics. The primary purpose of these tests was to obtain wind-tunnel data on the load distribution on the cellule to be correlated with similar information obtained in flight tests, both to be used for design purposes. Because of the importance of the conditions beyond the stall as affecting the control and stability, this investigation was extended through 90 degree angle of attack. The results for the range of normal flight have been given in NACA Technical Report No. 271. The present paper presents the same results in a different form and includes, in addition, those over the greater range of angle of attack, -18 degrees through 90 degrees. The results show that: (1) at angles of attack above maximum lift, the biplane upper wing pressures are decreased by the shielding action of the lower wing. (2) the burble of the biplane lower wing, with respect to the angle of attack, is delayed, due to the shielding action of the lower wing. (3) the center of pressure of the biplane upper wing (semispan) is, in general, displaced forward and outward with reference to that of the wing as a monoplane, while for the lower wing there is but slight difference for both conditions. (4) the overhanging portion of the upper wing is little affected by the presence of the lower wing.

    The composition of human skin acts as a natural habitat for various bacterial species that function in a commensal and symbiotic fashion. In a healthy individual, bacterial flora serves to protect the host. Under certain conditions such as minor trauma, impaired host immunity, or environmental factors, the risk of developing skin infections is increased. Although a large majority of bacterial associated skin infections are common, a portion can potentially manifest into clinically significant morbidity. For example, Gram-positive species that typically reside on the skin such as Staphylococcus and Streptococcus can cause numerous epidermal (impetigo, ecthyma) and dermal (cellulitis, necrotizing fasciitis, erysipelas) skin infections. Moreover, the increasing incidence of bacterial antibiotic resistance represents a serious challenge to modern medicine and threatens the health care system. Therefore, it is critical to develop tools and strategies that can allow us to better elucidate the nature and mechanism of bacterial virulence. To this end, mass spectrometry (MS)-based proteomics has been revolutionizing biomedical research, and has positively impacted the microbiology field. Advances in MS technologies have paved the way for numerous bacterial proteomes and their respective post translational modifications (PTMs) to be accurately identified and quantified in a high throughput and robust fashion. This technological platform offers critical information with regards to signal transduction, adherence, and microbial–host interactions associated with bacterial pathogenesis. This mini-review serves to highlight the current progress proteomics has contributed toward the understanding of bacteria that are associated with skin related diseases, infections, and antibiotic resistance.

    The incidence of deep neck space infections has dramatically decreased since the advent of antibiotics, but with delayed treatment they carry the potential for significant morbidity and mortality. Odontogenic infections with involvement of the submandibular space are the most common source of deep neck space infections in adults, whereas in the pediatric population the most common cause is acute tonsillitis with involvement of the peritonsillar space. The newest group of patients at risk for deep neck space infections are intravenous drug abusers who inject the major vessels of the neck. Knowledge of neck spaces and fascial relationships is important in understanding the presentation, treatment, and complications of deep neck space infections. The spaces, which are created by various fasciae of the head and neck, are only potential spaces in that under normal conditions they cannot be examined clinically or radiographically. As the spaces are invaded by bacteria, a cellulitis or abscess occurs, and this infection may travel through paths of least resistance from one space to another.

    BACKGROUND / OBJECTIVES The aim of this study was to perform a retrospective analysis characterizing patients receiving tube feeding following percutaneous endoscopic gastrostomy ( PEG) tube placement between 2004 and 2012 at Erciyes University Hospital in Turkey. METHODS Patients above the age of 18 years, who required long term enteral tube feeding were studied. All PEGs were performed using the pull-through technique by one experienced endoscopist Demographic, clinical outcomes, and PEG-related complication data were collected. RESULTS Of the 128 subjects studied, 91 were male (71%) and 37 were female (29%). The mean age of this patient population was 54±19 years. The most common reason for PEG tube insertion was inability to consume oral diet due to complications of cerebrovascular disease (CVD; 27%), while cerebral hypoxia, occuring after non-neurological medical disorders, was the second most common indication (23%). A total of 70 patients (55%) had chronic comorbidities, with hypertension the most common (20%). The most common procedure related complication was insertion site bleeding, which occurred in 4 % of patients. Long term complications, during one year were insertion site cellulitis, gastric contents leakage, and peristomal ulceration occurred in 14%, 5%, and 0.5% of patients, respectively. There were no PEG insertion-related mortalities; one-year mortality was unrelated to the indication for PEG tube insertion. CONCLUSIONS PEG tube insertion was a safe method to provide enteral access for nutrition support in this hospitalized patient population. PMID:24518749

    Bacterial vaginosis (BV) is the most common of the vaginitides affecting women of reproductive age. It appears to be due to an alteration in the vaginal ecology by which Lactobacillus spp., the predominant organisms in the healthy vagina, are replaced by a mixed flora including Prevotella bivia, Prevotella disiens, Porphyromonas spp., Mobiluncus spp., and Peptostreptococcus spp. All of these organisms except Mobiluncus spp. are also members of the endogenous vaginal flora. While evidence from treatment trials does not support the notion that BV is sexually transmitted, recent studies have shown an increased risk associated with multiple sexual partners. It has also been suggested that the pathogenesis of BV may be similar to that of urinary tract infections, with the rectum serving as a reservoir for some BV-associated flora. The organisms associated with BV have also been recognized as agents of female upper genital tract infection, including pelvic inflammatory disease, and the syndrome BV has been associated with adverse outcome of pregnancy, including premature rupture of membranes, chorioamnionitis, and fetal loss; postpartum endometritis; cuff cellulitis; and urinary tract infections. The mechanisms by which the BV-associated flora causes the signs of BV are not well understood, but a role for H2O2-producing Lactobacillus spp. in protecting against colonization by catalase-negative anaerobic bacteria has been recognized. These and other aspects of BV are reviewed. PMID:1747864

    Objective To determine effectiveness of receipt of care from podiatrist and lower extremity clinician specialists (LEC specialists) on diabetes mellitus (DM)-related lower extremity amputation. Data Sources Medicare 5 percent sample claims, 1991–2007. Study Design Individuals with DM-related lower extremity complications (LECs) were followed 6 years. Visits with podiatrists, LEC specialists, and other health professionals were tracked to ascertain whether receipt of such care reduced the hazards of an LEC amputation. Data Collection Individuals were stratified based on disease severity, Stage 1—neuropathy, paresthesia, pain in feet, diabetic amyotrophy; Stage 2—cellutis, charcot foot; Stage 3—ulcer; Stage 4—osteomyelitis, gangrene. Principal Findings Half the LEC sample died within 6 years. More severe lower extremity disease increased risk of death and amputation. Persons visiting a podiatrist and an LEC specialist within a year before developing all stage complications were between 31 percent (ulceration) and 77 percent (cellulitis and charcot foot) as likely to undergo amputation compared with individuals visiting other health professionals. Conclusions Individuals with an LEC had high mortality. Visiting both a podiatrist and an LEC specialist in the year before LEC diagnosis was protective of undergoing lower extremity amputation, suggesting a benefit from multidisciplinary care.

    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. PMID:25870723

    Electrospinning of biopolymers has gained significant interest for the fabrication of fibrous mats for potential applications in tissue engineering, particularly for wound dressing and skin regeneration. In this study, for the first time, we report successful electrospinning of chitosan-based biopolymers containing bacterial cellulous (33 wt %) and medical grade nanodiamonds (MND) (3 nm; up to 3 wt %). Morphological studies by scanning electron microscopy showed that long and uniform fibers with controllable diameters from 80 to 170 nm were prepared. Introducing diamond nanoparticles facilitated the electrospinning process with a decrease in the size of fibers. Fourier transform infrared spectroscopy determined hydrogen bonding between the polymeric matrix and functional groups of MND. It was also found that beyond 1 wt % MND, percolation networks of nanoparticles were formed which affected the properties of the nanofibrous mats. Uniaxial tensile testing of the woven mats determined significant enhancement of the strength (from 13 MPa to 25 MP) by dispersion of 1 wt % MND. The hydrophilicity of the mats was also remarkably improved, which was favorable for cell attachment. The water vapor permeability was tailorable in the range of 342 to 423 µg·Pa−1·s−1·m−1. The nanodiamond-modified mats are potentially suitable for wound healing applications. PMID:27399726

    This study was completed to understand the usage patterns, system performance, degree of satisfaction, complications, and health benefits as perceived by recipients of a surgically implanted neuroprosthesis for exercise, standing, and transfers in individuals with low-cervical or thoracic spinal cord injury (SCI). A standardized telephone survey was administered to 11 recipients of the Case Western Reserve University/Veterans Affairs (CWRU/VA) implanted standing neuroprosthesis with more than 12 months of experience with the functional electrical stimulation (FES) system. Nine implant recipients were using the neuroprosthesis regularly for standing and/or exercising at the time of the survey. All 11 implant recipients noted improved health and a reduced incidence of pressure sores, leg spasms, and urinary tract infections (UTIs). No incidents of deep-vein thrombosis, infection, cellulitis, or electrical burns because of the neuroprosthesis were noted. System recipients uniformly felt that the neuroprosthesis resulted in better overall health and general well-being. Subjects were moderately to very satisfied with the performance of the neuroprosthesis and unanimously expressed a willingness to repeat the surgery and rehabilitation to obtain the same clinical outcome. All implant recipients reported the system to be safe, reliable, and easy to use. The implanted standing neuroprosthesis appears to be a clinically acceptable and effective means of providing the ability to exercise, stand, and transfer to selected individuals with paraplegia or low tetraplegia.

    On 30 June 1559, Henry II, King of France, was mortally wounded in the head by a lance during a jousting match. Despite the best efforts of his physicians, Ambroise Paré and Andreas Vesalius, King Henry died 11 days later. This article, based on previously unpublished evidence, aims at examining the historical account of his death against modern medical practice to establish the probable cause of the king's death. We also discuss what treatments the doctors in the sixteenth century may have had to offer. Historical accounts of the joust provide details of the incident including the position of the visor of the king's helmet. Descriptions of the wood fragments removed from the right orbit by Italian observers and a new translation of the autopsy by Andreas Vesalius allow an accurate description of the actual injury. Our research counters previous theories and concludes that Henry II was the victim of craniofacial trauma involving the right eye and that he died from periorbital cellulitis caused by a retained foreign body in the wound, complicated by a left interhemispheric empyema preceded by a traumatic interhemispheric haematoma. It would appear that the royal court doctors advocated a wait-and-see strategy, with little actual input from Ambroise Paré or Andreas Vesalius, with a clearly regrettable outcome. PMID:25421951

    Veno-occlusive disease (VOD) is a complication arising from the toxicity of conditioning regimens that have a significant impact on the survival of patients who undergo stem cell transplantation. There are several known risk factors for developing VOD and their assessment before the start of conditioning regimens could improve the quality of care. Equally important are early identification of signs and symptoms ascribable to VOD, rapid diagnosis, and timely adjustment of support therapy and treatment. Nurses have a fundamental role at the stages of assessment and monitoring for signs and symptoms; therefore, they should have documented skills and training. The literature defines nurses’ areas of competence in managing VOD, but in the actual clinical practice, this is not so clear. Moreover, there is an intrinsic difficulty in managing VOD due to its rapid and often dramatic evolution, together with a lack of care tools to guide nurses. Through a complex evidence-based process, the Gruppo Italiano per il Trapianto di Midollo Osseo (GITMO), cellule staminali emopoietiche e terapia cellulare nursing board has developed an operational flowchart and a dynamic monitoring tool applicable to haematopoietic stem cell transplantation patients, whether they develop this complication or not.

    Loxocelism is a toxic condition produces by the venom inoculated by the bit of the recluse spider (genus Loxosceles). In can appear in two clinical forms: cutaneous loxocelism and viscerocutaneous Ioxocelim. The species Loxoceles rufescens, found in Spain, is responsible of cases of cutaneous loxocelism. Cutaneous loxocelism starts with an itch, later giving rise to intense pain, and it later takes either a more or less severe necrotic form or an edematous form. The latter, with a better prognosis, is the one we focus on here. The diagnosis is clinical. The systemic treatment consists in analgesics, antihistamines, corticosteroids, broad-spectrum antibiotics, and dapsone in severe cases. The local treatment is based on the cleaning and debridement of the wound, and in advanced treatments for complex wounds. It is not uncommon that such wounds require skin grafting. We present the case of an 18-year female bitten by a loxosceles on the dorsal area of the foot. She developed a deep tissue necrosis in the area. She presented systemic complications such as leucocitosis, fever, local infection and cellulitis. Systemic treatment and hospitalization were required, as well as advanced therapeutic care. Finally, cutaneous integrity was restored after 84 days.

    INTRODUCTION Acinetobacter baumannii is usually associated with respiratory tract, urinary tract and bloodstream infections. Recent reports suggest that it is increasingly causing skin and soft tissue infections. It is also evolving as a multidrug resistant organism that can be difficult to treat. We present a fatal case of multidrug resistant A. baumannii soft tissue infection and review of relevant literature. PRESENTATION OF CASE A 41 year old morbidly obese man, with history of alcoholic liver disease presented with left superficial pre-tibial abrasions and cellulitis caused by multidrug resistant (MDR) A. baumannii. In spite of early antibiotic administration he developed extensive myositis and fat necrosis requiring extensive and multiple surgical debridements. He deteriorated despite appropriate antibiotic therapy and multiple surgical interventions with development of multi-organ failure and died. DISCUSSION Managing Acinetobacter infections remains difficult due to the array of resistance and the pathogens ability to develop new and ongoing resistance. The early diagnosis of necrotizing soft tissue infection may be challenging, but the key to successful management of patients with necrotizing soft tissue infection are early recognition and complete surgical debridement. CONCLUSION A. baumannii is emerging as an important cause of severe, life-threatening soft tissue infections. Multidrug resistant A. baumannii soft tissue infections may carry a high mortality in spite of early and aggressive treatment. Clinicians need to consider appropriate early empirical antibiotic coverage or the use of combination therapy to include MDR A. baumannii as a cause of skin and soft tissue infections. PMID:25016080

    2010-10-01

    Periprosthetic joint infection (PJI) is caused by haematogenous spread from a distant primary infection in 70% of deep infections. It can potentially be avoided by prompt recognition and treatment of the primary infection focus in susceptible patients. Streptococci are commonly implicated in such secondary infections. Group A, B, C and G streptococci can cause invasive, potentially life-threatening infection. Risk factors include diabetes, immunodeficiency and venous insufficiency Any patient with a joint replacement should be counselled to seek early attention for any soft tissue or dental infection. A course of antibiotics should be considered in any wound in which there has been significant contamination. Patients at risk of infection through impaired physical defences such as chronic venous insufficiency should be treated appropriately and consideration should be given to prophylactic treatment of varicose veins if there are early signs of chronic venous insufficiency. Mild, uncomplicated cellulitis can be treated with oral antibiotics, simple penicillin agents such as amoxicillin or flucloxacillin should be administered. Patients should be referred to hospital for consideration of parenteral antibiotics if they are exhibiting signs of systemic sepsis such as tachycardia, pyrexia or hypotension. PJI should be suspected if a patient with a joint replacement develops pain in that joint after a soft tissue, respiratory tract or dental infection. In cases of suspected PJI prompt orthopaedic advice should be sought and antibiotics withheld.

    Mucormycosis and aspergillosis are two opportunistic fungal infections, which can evolve into life-threatening complications. They generally affect patients with relevant risk factors such as immunocompromisation or long-term use of antibiotics or corticosteroids. Treatment usually combines medical and surgical approaches, often including extended necrosectomies, although the prognosis of generalized fungal infections is very poor. In this paper, we present the case of a 17-year-old girl affected by combined aspergillosis and mucormycosis, following treatment of a recurrent glioma. The patient was hospitalized for a suspected cellulitis of the right hemi-face, involving frontal maxillary area and the upper airways and was immediately put on intravenous antibiotic therapies; after performing nasal septum and maxillary biopsies, concomitant mucormycosis and aspergillosis were diagnosed and antimycotic therapy with liposomal B-amphotericin was administered. After evaluation by the oral surgeon and otolaryngologist, surgical cranio-facial necrosectomy was suggested, but refused by the parents of the patient. The girl died only few days later, due to a respiratory arrest. Awareness of this pathology with prompt diagnosis and early treatment may improve the outcome of these infections and reduce the mortality. PMID:27350324

    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

    In England and Wales, meningococcal disease caused by group W has historically been associated with outbreaks of disease among travellers to high-risk countries. Following a large outbreak associated with travel to the Hajj in 2000, the number of cases declined and, in 2008, only 19 laboratory-confirmed cases were identified nationally. In 2013, in the East Midlands region of England, eight cases of meningococcal disease caused by this serogroup were recorded, compared with six from 2011 to 2012. To explore this further, data for all cases with a date of onset between 1 January 2011 and 31 December 2013 were collected. Data collected included geographical location, clinical presentation and outcome. Fourteen cases were identified; two died as a result of their illness and two developed long-term health problems. No commonality in terms of geographical location, shared space or activities was identified, suggesting that group W is circulating endemically with local transmission. Clinical presentation was variable. Half presented with symptoms not typical of a classical meningococcal disease, including two cases of cellulitis, which may have implications for clinicians, in terms of timely identification and treatment, and public health specialists, for offering timely antibiotic chemoprophylaxis to close contacts.

    Introduction: The frequently used irrigant in dental surgery, sodium hypochlorite, is occasionally the cause of minor, usually circumscribed, adverse effects. Severe, extensive complications, with lasting sequelae, however, also can occur, as in the case we report herein. Case Report: A 55-year-old woman underwent an endodontic procedure on a maxillary molar, whose roots, unknown to the surgeon, were protruding into the maxillary sinus. After sodium hypochlorite root canal irrigation, the patient immediately developed intense facial pain, facial edema, and periorbital cellulitis. An emergency department evaluation diagnosed an intense inflammatory disease of the maxillary sinus, with significant destruction of its bony walls, accompanied by midface paraesthesia due to infraorbital nerve injury. In the following weeks, the patient slowly developed enophthalmos due to bone erosion of the orbit floor. Treatment, besides prolonged oral steroids, required the endoscopic endonasal opening of the maxillary sinus for profuse irrigation. Two years later, the patient maintained a complete loss of function of the maxillary sinus, anesthesia-paraesthesia of the midface, and inferior dystonia of the eye with an enophthalmos. Conclusion: Dentists, maxillofacial surgeons, and otorhinolaryngologists should all be aware of the whole spectrum of complications of even the simplest dental work. Sodium hypochlorite irrigations should be used cautiously in root canal surgery, with the full awareness of its potential for causing soft-tissue damage. PMID:27465790

    Abstract Helicobacter fennelliae is a gram-negative, spiral bacillus that appears as thin-spread colonies on sheep blood agar and is similar to Helicobacter cinaedi. H fennelliae is diagnosed by genetic testing, which is not readily available in all laboratories. Therefore, H fennelliae bacteremia has only been reported sporadically, and little is known about its clinical characteristics. We describe 3 cases of H fennelliae bacteremia with gastrointestinal symptoms, including nausea, vomiting, and diarrhea. Isolates could be differentiated from H cinaedi by biochemical reaction testing, including nitrate reduction and alkaline phosphatase hydrolysis. We retrospectively reviewed 24 cases of H fennelliae bacteremia reported in the literature. Most of the patients had immunosuppressive backgrounds, including solid tumors, hematological malignancies, and autoimmune diseases. Although gastrointestinal symptoms were common, cellulitis was not often observed in patients with H fennelliae bacteremia. Clinicians should bear in mind that H fennelliae may be a differential diagnosis in patients with gastrointestinal manifestations and gram-negative, spiral bacilli. In addition, biochemical reactions, such as nitrate reduction and alkaline phosphatase hydrolysis, are useful in differentiating H fennelliae from H cinaedi. PMID:27149471

    Infectious disease physicians in university and community practices completed a standard data form following each of 1,366 inpatient consultations during a 7-month period. The rate of consultation was higher in the university practice than in the community practice (3.4 vs. 1.8 per 100 discharges, respectively). Known or suspected bacterial pathogens accounted for more than half of all consultations in both practice groups. The three organ systems most commonly affected by infection were pulmonary (20% in university practice vs. 19% in community practice), skin and soft tissue (13% in university practice vs. 20% in community practice), and musculoskeletal (12% in university practice vs. 16% in community practice). Bloodstream infection, pneumonia, unexplained fever, osteomyelitis, urinary tract infection, and cellulitis were the six most common disease processes that led to consultation in both practice groups. The percentage of patients with noninfectious diseases and the percentage for whom a change in antimicrobial therapy was advised was nearly identical in both practice settings. Physicians in private practice performed more consultations on weekends (20% vs. 11% in university practices, P < .001) and between 6:00 P.M. and 7:00 A.M. (15% vs. 6% in university practices, P < .001). The scope and diversity of the work of consultants in community practices are nearly identical to those of their colleagues in university-based practices.

    Introduction: The incidence of deep vein thrombosis (DVT) in pediatric patients is significantly much lower than adults. Most of the pediatric in-patients with major trauma, sepsis do not undergo routine screening for DVT. Case report: We present a case of a 12-year-old boy presented to us with minor trauma to right ankle associated with swelling, pain and had associated cough, and fever. On investigation with plain X-ray of right ankle/chest, and blood parameters, patient was suspected of having cellulitis of right leg with chest infection. Patient was treated with IV Cloxacillin and ample of rest. During the course of treatment, patient’s condition deteriorated with fever, tachycardia and a swollen leg without much pain. Duplex scan was performed where the right leg revealed thrombosis of popliteal vein, while CT scan of chest with angiogram ruled out possibility of pulmonary embolism. However, CT chest showed pneumonia with pulmonary effusion. Patient was treated with low molecular heparin and IV Cloxacillin for pneumonia. Patient recovered completely and there was no recurrence during follow up period of 6 months. Conclusion: The possibility of DVT in pediatric should be kept in mind and when suspected, should be properly investigated and treated. PMID:27299134

    2016-01-01

    The symptoms of Staphylococcal scalded skin syndrome (SSSS) include blistering of skin on superficial layers due to the exfoliative toxins released from Staphylococcus aureus. After the acute exfoliation of skin surface, erythematous cellulitis occurs. The SSSS may be confined to few blisters localized to the infection site and spread to severe exfoliation affecting complete body. The specific antibodies to exotoxins and increased clearence of exotoxins decrease the frequency of SSSS in adults. Immediate medication with parenteral anti-staphylococcal antibiotics is mandatory. Mostly, SSSS are resistant to penicillin. Penicillinase resistant synthetic penicillins such as Nafcillin or Oxacillin are prescribed as emergency treatment medicine. If Methicillin-resistant Staphylococcus aureus (MRSA) is suspected), antibiotics with MRSA coverage (e.g., Vancomycin or Linezolid) are indicated. Clindamycin is considered as drug of choice to stop the production of exotoxin from bacteria ribosome. The use of Ringer solution to to balance the fluid loss, followed by maintainence therapy with an objective to maintain the fluid loss from exfoliation of skin, application of Cotrimoxazole on topical surface are greatlly considered to treat the SSSS. The drugs that reduce renal function are avoided. Through this article, an attempt has been made to focus the source, etiology, mechanism, outbreaks, mechanism, clinical manisfestation, treatment and other detail of SSSS.

    Veno-occlusive disease (VOD) is a complication arising from the toxicity of conditioning regimens that have a significant impact on the survival of patients who undergo stem cell transplantation. There are several known risk factors for developing VOD and their assessment before the start of conditioning regimens could improve the quality of care. Equally important are early identification of signs and symptoms ascribable to VOD, rapid diagnosis, and timely adjustment of support therapy and treatment. Nurses have a fundamental role at the stages of assessment and monitoring for signs and symptoms; therefore, they should have documented skills and training. The literature defines nurses’ areas of competence in managing VOD, but in the actual clinical practice, this is not so clear. Moreover, there is an intrinsic difficulty in managing VOD due to its rapid and often dramatic evolution, together with a lack of care tools to guide nurses. Through a complex evidence-based process, the Gruppo Italiano per il Trapianto di Midollo Osseo (GITMO), cellule staminali emopoietiche e terapia cellulare nursing board has developed an operational flowchart and a dynamic monitoring tool applicable to haematopoietic stem cell transplantation patients, whether they develop this complication or not.

    Many skin and skin-related diseases affect the sexes unequally, with attendant implications for public health and resource allocation. To evaluate better the incidence of skin and skin-related diseases affecting males vs. females, we reviewed published population-based epidemiology studies of skin disorders performed utilizing Rochester Epidemiology Project data. Females had a higher incidence of the following diseases: connective tissue diseases (scleroderma, morphea, dermatomyositis, primary Sjögren syndrome, systemic lupus erythematosus [not in all studies]), pityriasis rosea, herpes progenitalis, condyloma acuminatum, hidradenitis suppurativa, herpes zoster (except in children), erythromelalgia, venous stasis syndrome, and venous ulcers. Males had a higher incidence of psoriasis and psoriatic arthritis, basal cell carcinoma (exception, females aged ≤40 years), squamous cell carcinoma, and lentigo maligna. Incidence rates were equal in males and females for cutaneous malignant melanoma (exception, higher in females aged 18-39 years), lower-extremity cellulitis, cutaneous nontuberculous mycobacterial infection, Behçet disease, delusional infestation, alopecia areata, and bullous pemphigoid. Many of the population-based sex-specific incidence rates of skin and skin-related diseases derived from the Rochester Epidemiology Project are strikingly different from those estimated elsewhere. In general, females are more commonly affected by skin and skin-related diseases. The reasons for this imbalance remain to be determined and are likely multifactorial. PMID:27009931

  16. Serious soft tissue infections of the head and neck

    The head and neck contain a number of spaces that can be invaded by organisms of the mouth or by spread of cervical osteomyelitis. Infection in these spaces may progress from superficial infection to cellulitis to the formation of an abscess requiring immediate drainage. Spread of infection between spaces depends on anatomic location. Most patients require hospitalization and intravenous antibiotic therapy. Because a deep space infection may be occult, a high index of suspicion is required for diagnosis. Early recognition is necessary to avoid tissue damage, bacteremia or airway compromise. The possibility of deep space infection should be considered in any patient who does not respond to the usual treatment of an abscessed tooth or tonsillitis. This type of infection also should be considered in a toxic patient who has a fever of unknown origin, with or without blood cultures that show anaerobic organisms. Computed tomography or magnetic resonance imaging is usually necessary to locate the infection and to detect suppuration that will be amenable to surgical exploration and drainage. 25 references.

    A 9-month-old baby girl presented multiple times with an erythematous, papular and pustular big toe in an otherwise healthy infant. A diagnosis of cellulitis was made and she was started on oral antibiotics, and bacterial swabs were taken. After 2 weeks of worsening appearance she was admitted for intravenous antibiotics. Inflammatory markers remained normal and viral swabs were taken. No improvement was seen after 2 days and she was referred for orthopaedic and dermatological opinions. The orthopaedic team recommended debridement whereas the dermatologist suspected a primary herpetic whitlow and recommended intravenous acyclovir in addition to intravenous antibiotics. A viral swab for Herpes simplex virus type 1 (HSV1) was positive by PCR on day 3. The toe continued to improve clinically and the patient received 21 days of acyclovir in total. 27 days after discharge the infection relapsed. She was treated with a further 14 days of oral acyclovir and recovered completely. PMID:23436893

    Since 2007, 21 female and 1 male patient aged 25 to 55 years, who either did not have any obvious causative infection source or, despite the presence of nonvital teeth, did not display typical symptoms of odontogenic infection, were treated for acute facial inflammation. All these patients admitted previous application of injectable soft tissue fillers (ISTFs) performed in either private plastic surgery and dermatology practices or cosmetic salons. The period between injection and infection varied from 1 week to 6 years. The injected substance remained unknown in many cases. Of the 22 patients, 3 were diagnosed with facial cellulitis, 4 with periorbital abscess, and 15 with a buccal space abscess. ISTFs provide an attractive option in facial rejuvenation. With their increasing use, the prevalence of complications is also expected to increase. Infectious complications of ISTFs were previously unknown in Kuwait. Although these products are primarily meant for treatment of the aging face, the age pattern of our patients suggests their frequent misuse and spurious indications. Especially worrisome is the recently observed application of fillers in cosmetic salons. We believe that the use of ISTFs should be regulated and their administration in nonmedical facilities prohibited. Patients with an atypical course of facial inflammation should be questioned about a history of cosmetic procedures.

    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.

    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

  1. Molecular defects in the mannose binding lectin pathway in dermatological disease: Case report and literature review

    PubMed Central

    2010-01-01

    Mannose-binding lectin (MBL) and the Mannose-binding lectin-associated serine proteases (MASPs) are an essential aspect of innate immune responses that probably play an important but understudied role in cutaneous function. The MBL-MASP pathway appears to exert its primary role by assisting in the clearance of apoptotic skin cells (thus preventing accumulation and a subsequent autoimmune response) and promoting opsonophagocytosis of invading pathogens, limiting their dissemination. Deficiencies of the pathway have been described and are associated with infectious, autoimmune and vascular complications. However, the role of this pathway in dermatological disease is essentially unexplored. We describe 6 patients presenting with recurrent inflammatory and/or infectious skin conditions who also demonstrated severely low MBL levels. One patient also had a defect in the MASP2 gene. Genotype analysis revealed specific point mutations in the MBL2 promoter in all 6 patients and a variant MASP-2 gene in one patient. Five patients presented recurrent pustular skin infections (cellulitis, folliculitis and cutaneous abscess). A case of Grover's disease and one forme fruste of Behcet's syndrome (orogenital ulcers) were also observed. The patients responded to antimicrobial therapy, although in some, recurrence of infection was the rule. It appears that MBL deficiency may contribute to recurrent skin infections and to certain forms of inflammatory skin disease. The mechanisms may relate to the role of this pathway in innate immunity, removal of apoptotic cells and in immune complexes. Further study of MBL pathway defects in dermatological disease is required. PMID:20338057

    Perifolliculitis capitis abscedens et suffodiens or dissecting cellulitis of the scalp is a rare, chronic destructive folliculitis of the scalp, characterized by painful nodules, purulent drainage, sinus tracts, keloid formation and cicatricial alopecia. The cause of the disease is unknown, but it is similar in many features to hidradenitis suppurativa and acne conglobata. In our case report, the patient's dermatologic appearance included one slightly erythematous, infiltrated alopecic area with draining lesions in the right parietal part of the scalp with a few alopecic areas in other parts of the scalp. The identification of the infectious agent, repeated swabs and KOH examination/or fungal cultures and tissue sampling for histopathologic analysis were necessary to confirm the diagnosis of perifolliculitis capitis abscedens et suffodiens. The patient received systemic antibiotics (azithromycin and amoxicillin-clavulanate) and oral antimycotic therapy (fluconazole), followed by a long period of oral isotretinoin with local skin care, which led to resolution and thus inhibited the evolution to scarring and nodular stage of the disease. Thus, such combined approach could be useful for other patients with these dermatologic problems. PMID:21703156

    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

    Aims: To record and analyse the technical aspects of neonatal tracheostomy and to suggest some solutions. Materials and Methods: This is a retrospective observational cohort of 37 cases of neonatal tracheostomies performed over 30 years (1985-2014). Results: Thirty-three of the 37 tracheostomies were done as an elective procedure and four done emergently. Eighteen neonatal tracheostomies were done with a low transverse cervical incision and 19 were done with low vertical cervical incision. Three patients had bleeding while exposing the trachea. Trachea could not easily be identified in 2 cases. Commercial tracheostomy tubes were used in only 20 cases. In 17 patients, the conventional endotracheal tubes 2.5 or 3fr size were used. There were 3 instances of wound infection out of which one has peri-tracheostomy necrotizing cellulitis and the neonate succumbed to sepsis. Two cases had surgical emphysema. No case had pneumothorax. Conclusion: We described tracheostomy in neonates in a resource constrained centre. Various makeshift arrangements can be used in absence of standard supplies.

    Skin of color, also known as ethnic skin, is described as skin of individuals of African, Asian, Hispanic, Native-American, Middle Eastern, and Pacific Island backgrounds. Differences in hair morphology, hair grooming, cultural practices, and susceptibility to keloid scarring exist within these populations and have been implicated in hair, scalp, and skin disorders. Acne keloidalis (AK), central centrifugal cicatricial alopecia (CCCA), dissecting cellulitis of the scalp (DCS), pseudofolliculitis barbae (PFB), traction alopecia (TA), and keloids are the most prevalent follicular and scarring disorders in skin of color. They have been associated with disfigurement, permanent hair loss, emotional distress, and decreased quality of life. Hair grooming practices, such as the use of chemical relaxers, heat straightening, and tight braiding and weaving can cause scalp irritation and follicular damage and are linked to the pathogenesis of some of these conditions. Consequently, patient education and behavior modifications are integral to the prevention and management of these disorders. Scarring disorders are also of concern in ethnic populations. Keloid scarring is more prevalent in individuals of African, Asian, and Hispanic descent. The scarring alopecia CCCA is almost exclusively seen in patients of African descent. Therapeutic regimens such as intralesional corticosteroids, surgical excision, and laser therapy can be effective for these follicular and scarring disorders, but carry a risk of dyspigmentation and keloid scarring. Ethnic skin and hair may present unique challenges to the clinician, and knowledge of these differences is essential to providing quality care. PMID:24820821

    Tumor necrosis factor-alpha (TNF)-alpha inhibitors are licensed for patients with severe refractory psoriasis and psoriatic arthritis. However, TNF-alpha inhibitors have also been used off-label for various recalcitrant mucocutaneous diseases. This study aimed to evaluate the efficacy and safety of TNF-alpha inhibitors used for off-label dermatological indications. We retrospectively evaluated patient records of 118 patients treated off-label with TNF-alpha inhibitors in a dermatological university department. Patients presented with severe aphthous stomatitis/genital aphthous lesions (26), chronic urticaria (25), hidradenitis suppurativa (29), acne conglobata (11), dissecting cellulitis of the scalp (two), orofacial granulomatosis (four), sarcoidosis (four), granuloma annulare (two), granulomatous rosacea (one), granuloma faciale (one), subcorneal pustulosis (one), pyoderma gangrenosum (four), Sweet's syndrome (four), Well's syndrome (one), benign familial pemphigus (one), lichen planus (one), and folliculitis decalvans (one). A significant number of these patients went into remission during therapy with TNF-alpha inhibitors. A total of 11 patients (9%) experienced severe adverse effects during therapy. Off-label therapy with TNF-alpha inhibitors may be considered for selected patients with severe recalcitrant mucocutaneous diseases. The risk of severe adverse effects signals that a thorough benefit-risk assessment should be performed before initiating off-label treatment with TNF-alpha inhibitors for these conditions.

    Hair loss in skin of color patients can vary from the very simplest of diagnoses to a unique diagnostic challenge requiring extensive knowledge of historical symptoms, haircare practices, and previous treatments. There are several disorders in the literature that are noted to be more common in patients of African descent as compared to Caucasian populations. These disorders include central centrifugal cicatricial alopecia, dissecting cellulitis, discoid lesions of lupus erythematosus, traction alopecia, seborrheic dermatitis, and hair breakage. While there is no definitive prevalence data for the various forms of hair loss in the skin of color population, it is clear that these disorders are a concern for many patients in this population along with common hair loss concerns, such as telogen effluvium and pattern hair loss. A careful detailed clinical examination, history, and potential histopathology will guide the clinician to appropriate management. Hair disorders in skin of color patients may present unique challenges to the clinician, and knowledge of accurate clinical presentation and treatment approaches is essential to providing quality care.

    Keratitis-Ichthyosis-Deafness syndrome is a rare congenital disorder of the ectoderm caused by mutations in the connexin-26 gene (GJB2) on chromosome 13q11-q12, giving rise to keratitis, erythrokeratoderma and neurosensory deafness. We report the case of a 31-year-old black male diagnosed as having KID syndrome. Sequencing analysis showed a heterozygous missense mutation D50N (148G > A) in the GJB2 gene. In addition to the classical features of vascularizing keratitis, erythrokeratoderma and congenital deafness, our patient presented a follicular occlusion triad with hidradenitis suppurativa (HS, alias acne inversa), acne conglobata and dissecting cellulitis of the scalp, leading to cicatricial alopecia and disfiguring, inflammatory vegetations of his scalp. Conservative therapy such as a keratolytic, rehydrating and antiseptic external therapy, antibiotic, antimycotic and retinoids were only of moderate benefit, so we finally chose the curative possibility of surgery therapy of the axillar papillomas and of the scalp. The inflammatory papillomatous regions of the axillae and of the scalp were radically debrided. Clean granulation was awaited and covered in a second session with a mesh graft from the thigh, achieving a satisfactory result. To our knowledge, only one case of KID syndrome occurring in association with follicular occlusion triad has been reported before. PMID:16172043

    Background ‘Flame hairs’ is a trichoscopic feature described as hair residue from pulling anagen hairs in trichotillomania. Objective: To detect whether flame hairs are present in other hair loss disorders. Methods We retrospectively, independently and blindly reviewed the trichoscopic images of 454 consecutive patients with alopecia areata (99 cases), trichotillomania (n = 20), acute chemotherapy-induced alopecia (n = 6), acute radiotherapy-induced alopecia (n = 2), tinea capitis (n = 13), lichen planopilaris (n = 33), frontal fibrosing alopecia (n = 60), discoid lupus erythematosus (n = 30), dissecting cellulitis (n = 11), central centrifugal cicatricial alopecia (n = 94) and traction alopecia (n = 86) for the presence of flame hairs. We prospectively obtained trichoscopy-guided scalp biopsies from flame hairs in trichotillomania, alopecia areata, traction alopecia and central centrifugal cicatricial alopecia (1 case each). Results Flame hairs were detected in 100% of the acute chemotherapy- and radiotherapy-induced alopecias, where they were the predominant hair abnormality. They were also found in trichotillomania (55%), alopecia areata (21%), traction alopecia (4%) and central centrifugal cicatricial alopecia (3%). On pathology, they corresponded to distorted hair shafts. Conclusion The flame hair is a type of broken hair which can be seen in various hair loss disorders. It results from traumatic pulling of anagen hairs or from anagen arrest due to inflammation or drugs. © 2015 S. Karger AG, Basel PMID:27171360

    Rupture of isolated posterior spinal artery (PSA) aneurysms is a rare cause of subarachnoid hemorrhage (SAH) that presents unique diagnostic challenges owing to a nuanced clinical presentation. Here, we report on the diagnosis and management of the first known case of an isolated PSA aneurysm in the context of leukocytoclastic vasculitis. A 53-year-old male presented to an outside institution with acute bilateral lower extremity paralysis 9 days after admission for recurrent cellulitis. Early magnetic resonance imaging was read as negative and repeat imaging 15 days after presentation revealed SAH and a compressive spinal subdural hematoma. Angiography identified a PSA aneurysm at T9, as well as other areas suspicious for inflammatory or post-hemorrhagic reactive changes. The patient underwent a multilevel laminectomy for clot evacuation and aneurysm resection to prevent future hemorrhage and to establish a diagnosis. The postoperative course was complicated by medical issues and led to the diagnosis of leukocytoclastic vasculitis that may have predisposed the patient to aneurysm development. Literature review reveals greater mortality for cervical lesions than thoracolumbar lesions and that the presence of meningitic symptoms portents better functional outcome than symptoms of cord compression. The outcome obtained in this case is consistent with outcomes reported in the literature. PMID:27114966

  11. Necrotizing fasciitis – a diagnostic dilemma: two case reports

    PubMed Central

    2014-01-01

    Introduction Necrotizing soft tissue infections can affect various tissue planes. Although predisposing etiologies are many, they mostly center on impaired immunity occurring directly or indirectly and loss of integrity of protective barriers which predispose to infection. The nonspecific presentation may delay diagnosis and favor high mortality. Case presentation Two case vignettes are presented. The first patient, a 44-year-old healthy South Asian man with a history of repeated minor traumatic injury presented to a primary health care center with a swollen left lower limb. He was treated with antibiotics with an initial diagnosis of cellulitis. Because he deteriorated rapidly and additionally developed intestinal obstruction, he was transferred to our hospital which is a tertiary health care center for further evaluation and management. Prompt clinical diagnosis of necrotizing soft tissue infection was made and confirmed on magnetic resonance imaging as necrotizing fasciitis. Urgent debridement was done, but the already spread infection resulted in rapid clinical deterioration with resultant mortality. The second patient was a 35-year-old South Asian woman with systemic lupus erythematous receiving immunosuppressive therapy who developed left lower limb pain and fever. Medical attention was sought late as she came to the hospital after 4 days. Her condition deteriorated rapidly as she developed septic shock and died within 2 days. Conclusions Necrotizing fasciitis can be fatal when not recognized and without early intervention. Clinicians and surgeons alike should have a greater level of suspicion and appreciation for this uncommon yet lethal infection. PMID:24965382

    Helicobacter spp., except for Helicobacter cinaedi, have only rarely been reported in cases of septicemia. A patient with X-linked (Bruton’s) agammaglobulinemia was found to have persistent sepsis with a Helicobacter-like organism despite multiple courses of antibiotics. His periods of sepsis were associated with leg swelling thought to be consistent with cellulitis. The organism was fastidious and required a microaerophilic environment containing H2 for growth. Optimal growth was observed at 35 to 37°C on sheep blood, CDC anaerobe, and Bordet-Gengou agars. Serial subcultures every 4 to 5 days were required to maintain viability. The organism was strongly urease positive and showed highest relatedness to Helicobacter-like organisms with the vernacular name “Flexispira rappini” by 16S rRNA gene sequence analysis. Genomic DNA hybridization studies, however, found 24 to 37% relatedness to “F. rappini” and even less to other Helicobacter spp. Although the organism phenotypically resembles “Flexispira” and Helicobacter, it is thought to represent a new taxon. The patient’s infection was eventually cleared with a prolonged (5-month) course of intravenous imipenem and gentamicin. PMID:10405381

    2015-01-01

    Calciphylaxis or uremic arteriolopathy is a complex process typically seen in patients with end-stage renal disease, but has also been reported in patients with normal renal function. However, therapies for calciphylaxis are based on reports of traditional patients (i.e., end-stage renal disease). A mainstay of therapy, sodium thiosulfate (STS), has been shown to be effective for the treatment of calciphylaxis. Without a standardized therapy reported for nondialysis patients there is a need for evidence-based therapy. Here, we report a case of a 63-year-old woman with an acute injury on chronic kidney disease (CrClBaseline = 48 mL/min, CrClAKI = 36 mL/min), not requiring dialysis, with warfarin-induced calciphylaxis. After 4 weeks of therapy with STS, sevelamer, alendronate, and enzymatic debridement the patient subjectively reported slight improvement of the necrotic ulcers but developed cellulitis on her nonaffected limb. Additionally, after 12 weeks of therapy she was readmitted for renal failure and subsequently required dialysis. PMID:26816477

  15. Pilonidal sinus disease and tuberculosis.

    Gupta, P J

    2012-01-01

    Pilonidal disease is a disease of young people, usually men, which can result in an abscess, draining sinus tracts, and moderate debility for some. It probably results from hair penetration beneath the skin, for reasons that are not totally clear. A pilonidal sinus in the sacrococcygeal region is associated with recurrent infection, abscess formation, cellulitis, and fistulae. The infection is usually chronic and non-specific. However, few reports of granulomatous infection like tuberculosis and actinomycosis in pilonidal sinus have been observed. The presentation of tuberculosis in these sinuses may have wide forms, with atypical and uncharacteristic clinical picture, making it difficult to make a diagnosis preoperatively. This paper discusses about pilonidal sinus disease and tubercular infiltration in these sinuses. The diagnosis of tuberculosis in pilonidal sinus disease is elusive, necessitating a high index of suspicion. The literature on the tubercular affliction of pilonidal sinus is scant. Novel diagnostic modalities such as adenosine deaminase levels and polymerase chain reaction (PCR) can be useful in doubtful situations. Physicians should obtain a thorough history focusing on risk behaviors for human immunodeficiency virus infection (HIV) and tuberculosis. Treatment comprises of standard regimen of antitubercular medication and a modest surgical approach towards the sinuses. PMID:22338544

  16. Imaging of orbital disorders.

    Diseases of the orbit can be categorized in many ways, but in this chapter we shall group them according to etiology. Inflammatory diseases of the orbits may be infectious or noninfectious. Of the infections, orbital cellulitis is the most common and typically arises as a complication of acute sinusitis. Of the noninfectious, inflammatory conditions, thyroid orbitopathy is the most common and results in enlargement of the extraocular muscles and proliferation of the orbital fat. Idiopathic orbital inflammatory syndrome is another cause of inflammation in the orbit, which may mimic thyroid orbitopathy or even neoplasm, but typically presents with pain. Masses in the orbit may be benign or malignant and the differential diagnosis primarily depends on the location of the mass lesion, and on the age of the patient. Lacrimal gland tumors may be lymphomas or epithelial lesions of salivary origin. Extraocular muscle tumors may represent lymphoma or metastases. Tumors of the intraconal fat are often benign, typically hemangiomas or schwannomas. Finally, globe tumors may be retinoblastomas (in children), or choroidal melanomas or metastases in adults.

  17. Positive amplitudes in the amplituhedron

    The all-loop integrand for scattering amplitudes in planar SYM is determined by an "amplitude form" with logarithmic singularities on the boundary of the amplituhedron. In this note we provide strong evidence for a new striking property of the superamplitude, which we conjecture to be true to all loop orders: the amplitude form is positive when evaluated inside the amplituhedron. The statement is sensibly formulated thanks to the natural "bosonization" of the superamplitude associated with the amplituhedron geometry. However this positivity is not manifest in any of the current approaches to scattering amplitudes, and in particular not in the cellulations of the amplituhedron related to on-shell diagrams and the positive grassmannian. The surprising positivity of the form suggests the existence of a "dual amplituhedron" formulation where this feature would be made obvious. We also suggest that the positivity is associated with an extended picture of amplituhedron geometry, with the amplituhedron sitting inside a co-dimension one surface separating "legal" and "illegal" local singularities of the amplitude. We illustrate this in several simple examples, obtaining new expressions for amplitudes not associated with any triangulations, but following in a more invariant manner from a global view of the positive geometry.

    Venous disease is the most common cause of chronic leg ulceration and represents an advanced clinical manifestation of venous insufficiency. Due to their frequency and chronicity, venous ulcers have a high socioeconomic impact, with treatment costs accounting for 1% of the health care budget in Western countries. The evaluation of patients with venous ulcers should include a thorough medical history for prior deep venous thrombosis, assessment for an hypercoagulable state, and a physical examination. Use of the CEAP (clinical, etiology, anatomy, pathophysiology) Classification System and the revised Venous Clinical Severity Scoring System is strongly recommended to characterize disease severity and assess response to treatment. This venous condition requires lifestyle modification, with affected individuals performing daily intervals of leg elevation to control edema; use of elastic compression garments; and moderate physical activity, such as walking wearing below-knee elastic stockings. Meticulous skin care, treatment of dermatitis, and prompt treatment of cellulitis are important aspects of medical management. The pharmacology of chronic venous insufficiency and venous ulcers include essentially two medications: pentoxifylline and phlebotropic agents. The micronized purified flavonoid fraction is an effective adjunct to compression therapy in patients with large, chronic ulceration.

    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 effect of an extensive prophylactic antimicrobial regimen was prospectively assessed in 126 patients after high-dose chemotherapy and autologous PBSC. They received ciprofloxacin (500 mg/12 h), acyclovir (200 mg/6 h), and itraconazole (200 mg/12 h) orally until neutrophil recovery. Febrile patients received i.v. imipenem (500 mg/6 h) to which vancomycin and amikacin were added if fever persisted for 2-3 and 5 days, respectively. Amphotericin B lipid complex was further given on day 7 or 8 of fever. Median times for a neutrophil count of >0.5 x 10(9)/l and a platelet count of >20 x 10(9)/l were 9 and 11 days. Severe neutropenia (<0.1 x 10(9)/l) lasted for a median of 5 days in which 72% of febrile episodes and 50% of cases of bacteremia occurred. Gram-positive bacteria were isolated in 30 of 40 episodes of bacteremia, 25 of which were caused by Staphylococcus epidermidis. Clinical foci were the intravascular catheter in 35 cases, respiratory infection in 11, cellulitis in two, anal abscess in one, and neutropenic enterocolitis in one. The high incidence of febrile episodes (94%) and bacteremias (31%) may be due to the lack of efficacy of antimicrobial prophylaxis and the persistence of a 5-day period of severe neutropenia.

    Sea-urchin stings may produce injurious and venomous wounds. Although numerous writers refer to the danger of pedicellarial stings, there is little worth-while clinical data. We report a case of sea-urchin injury with severe local reaction and acute hepatitis. A 47-y-o Taiwanese woman accidentally stepped on a sea urchin while scuba diving on a beach in Palau Islands. The puncture wounds were numerous and she felt faintness, and immediate and intense pain. Initial management included partial spine removal, betadine immersion, intravenous fluid and analgesics. She developed fever, chills, nausea, and persistent serous discharge and tenderness from the sites of stings in the following days. She was admitted due to right foot cellulitis, sea-urchin injuries of both soles and suspected toxic hepatitis on the 7th day after envenomation. Serum alanine transaminase was 810 U/L and aspartate transaminase 320 U/L; she received i.v. antibiotics and wound debridement for removal of residual stings. She recovered gradually and was discharged 2 w later. Travel related marine animal injury has an increasing tendency throughout the world. This case had the unusual presentation of severe local reaction and hepatitis; immediate and more aggressive spine removal might have lessened the degree of injury.

    La mucocèle appendiculaire est une entité pathologique rare, mais potentiellement dangereuse, elle se présente sous différentes formes cliniques. Nous rapportons ici un cas d'une patiente âgée de 49 ans sans antécédents chirurgicaux chez qui nous avons découvert d'une façon fortuite cette affection. La clinique était celle d'un syndrome appendiculaire aigu patent et elle révélait une masse dans la fosse iliaque droite. Les examens de laboratoire ont montré une hyperleucocytose et une vitesse de sédimentation augmentée. L’échographie a démontré une masse kystique péricaecal. La patiente a subi une appendicectomie avec cæcectomie partielle et la pièce opératoire appendiculaire mesurait 153 mm de longueur et 64 mm de diamètre. L'analyse anatomopathologique de celle-ci a confirmé le diagnostic de mucocèle appendiculaire sans cellules de malignité. Les suites opératoires ont été simples et la patiente est sortie au cinquième jour postopératoire. PMID:25368725

    Les lymphomes malins non-hodgkiniens (LMNH) primitifs du sein sont des tumeurs rares. Leur symptomatologie clinique est polymorphe. L'imagerie médicale est non-spécifique. Le diagnostic peut être évoqué à l'examen cytologique, sa confirmation est toujours histologique. Il s'agit essentiellement de lymphomes de type B, ceux de type NK/T restant rares. Les plus fréquents sont les lymphomes diffus à grandes cellules présentant la particularité de donner des rechutes sous forme d'extension au système nerveux central. Nous rapportons un cas de LMNH primitif bilatéral du sein chez une patiente âgée de 33 ans, révélé par deux nodules mammaires bilatéraux. La mammographie et l'examen extemporané ont évoqué une tumeur phyllode. Le diagnostic du LMNH n'a été fait qu'après examen histologique définitif. Sous chimiothérapie, l’évolution était favorable avec un recul de 15 mois. PMID:27386030

    The purpose of this study is to demonstrate and discuss the radiological features of four patients with muscular hydatid disease and to evaluate the results of percutaneous treatment in these patients. Four patients (three female and one male) with six muscular hydatid cysts underwent percutaneous treatment and were followed up. The mean age of patients was 35 years (range: 12-60 years). Type I (n = 2), type II (n = 1), and type III (n = 3) hydatid cysts were observed in the thigh (n = 3) and gluteal (n = 1) region on radiologic examination. All interventions were performed under sonographic and fluoroscopic guidance. According to the type of the cyst, the procedure was carried out by either a 'catheterization technique with hypertonic saline and alcohol' or a 'modified catheterization technique.' The mean cathaterization time was 13.7 days, ranging from 1 to 54 days. The dimensions of the residual cavity were noted at every sonographic control, and an average of 96.1% volume reduction was obtained in six cysts of four patients. No sign of viability was observed during the follow-up period. Cavity infection and cellulitis were observed as complications, which resolved after medical therapy. Percutaneous treatment is a safe and effective procedure in patients with soft-tissue hydatid cysts and should be considered as a serious alternative to surgery.

    Bacterial skin infections, such as erysipelas or cellulitis, are characterized by fever and a painful erythematous rash. Despite the high prevalence of these infections, little is known about the underlying pathogenic mechanisms. This is partly due to the fact that a bacterial diagnosis is often difficult to attain. To gain insight into the pathogenesis of erysipelas, we investigated the samples obtained from infected and noninfected areas of skin from 12 patients with erysipelas. Bacterial cultures, detection of specific streptococcal antibodies in convalescent sera, and immunohistochemical analyses of biopsies indicated group A streptococcal etiology in 11 of the 12 patients. Also, electron micrographs of erythematous skin confirmed the presence of group A streptococcal cells and showed a limited solubilization of the surface-attached M protein. Degradation of high-molecular-weight kininogen and upregulation of the bradykinin-1 receptor in inflamed tissues indicated activation of the contact system in 11 patients. Analyses of release of the vasoactive heparin-binding protein (HBP) showed increased levels in the infected as compared with the noninfected areas. The results suggest that group A streptococci induce contact activation and HBP release during skin infection, which likely contribute to the symptoms seen in erysipelas: fever, pain, erythema, and edema.

    There are many rare cutaneous infections of the face. This phrase seems irrelevant, because rare infections in certain parts of the world are common in others. This is more apparent if applied to different sites of the body (eg, face). For instance, cutaneous leishmaniasis (CL) is common in Central and South America and uncommon in the United States. Because most medical practitioners in this country have never seen a case, it is easy for them to miss a diagnosis. Cutaneous leishmaniasis, a protozoan infection transmitted by phlebotomine sand flies, is typically divided into two forms: one found in the Middle East, Asia, Africa, and southern Europe, called Old World leishmaniasis, and one found in Latin and Central America, called New World leishmaniasis. Also atypical mycobacterial infection has been described in the medical literature since the mid-1950s. The development and introduction of a rapid radiometric mycobacterial detection system has advanced the field of mycobacteriology over the past 20 years. This method has allowed the distinction of Mycobacterium tuberculosis from other mycobacteria and enabled the performance of antimicrobial susceptibility testing of mycobacteria. The increased frequency of atypical mycobacterial infection stems from advances in the diagnostic procedures concerning the infection paired with the prevalence of mycobacterial disease in immunocompromised patients infected with HIV. Erysipelas and facial cellulitis are covered briefly in this paper.

    A 19-year-old man with chronic lymphoedema due to Noonan syndrome presented at our hospital with septic shock and pain in his lower leg. Blood cultures were positive for Streptococcus dysgalactiae subsp equisimilis (SDSE), resulting in a diagnosis of cellulitis with toxic involvement. He was treated with ampicillin for 3 weeks. Although he did well for 6 weeks, septic shock recurred. Blood culture again revealed SDSE, with the strain being identical to the first episode, suggesting that this infection had relapsed. He was treated with ampicillin for 6 weeks and prophylactically with trimethoprim-sulfamethoxazole for 12 months. Although SDSE bacteraemia occurs commonly in elderly patients, findings in this patient showed that it can also develop in younger persons with predisposing factors. This case also indicates that SDSE has the potential to recur, despite generally sufficient antibiotic administration, and that patients who experience recurrent episodes may require prolonged treatment with antibiotics, including prophylaxis.

    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.

    In England and Wales, meningococcal disease caused by group W has historically been associated with outbreaks of disease among travellers to high-risk countries. Following a large outbreak associated with travel to the Hajj in 2000, the number of cases declined and, in 2008, only 19 laboratory-confirmed cases were identified nationally. In 2013, in the East Midlands region of England, eight cases of meningococcal disease caused by this serogroup were recorded, compared with six from 2011 to 2012. To explore this further, data for all cases with a date of onset between 1 January 2011 and 31 December 2013 were collected. Data collected included geographical location, clinical presentation and outcome. Fourteen cases were identified; two died as a result of their illness and two developed long-term health problems. No commonality in terms of geographical location, shared space or activities was identified, suggesting that group W is circulating endemically with local transmission. Clinical presentation was variable. Half presented with symptoms not typical of a classical meningococcal disease, including two cases of cellulitis, which may have implications for clinicians, in terms of timely identification and treatment, and public health specialists, for offering timely antibiotic chemoprophylaxis to close contacts.

    There is great interest in new treatments of osteoporosis owing to general ageing of population and increased risk for fragility fractures in the elderly. Current therapies show a good efficacy in improving bone quality and bone density, but, in spite of a certain reduction in fracture rate, according to each treatment, the problem of osteoporotic fractures is yet far from to be solved. Moreover, some treatments may produce different side effects. Denosumab (Dmab), a receptor activator of nuclear factor kappa-B ligand (RANKL)-inhibitor, is an agent recently introduced in clinical practice for treatment of osteoporosis of postmenopausal women. Dmab has improved bone mineral density and prevented new vertebral and non-vertebral fractures with a similar efficacy in comparison with alendronate. Many clinical studies showed Dmab produces also significant improvement versus placebo in bone quality as indicated by decreasing markers of bone turnover. Patients using Dmab reported less risk of AFF (Atypical Femoral Fractures) and ONJ (Osteonecrosis of the Jaw) with an increased number of cellulitis. Here, we review articles using Dmab for female post-menopausal osteoporosis.

    The case of a 37-year-old cleaning worker, who applied to the court with a claim of being fired from her job due to permanent functional loss of her left arm triggered by a stroke following a work accident, is presented. The court has forwarded the case to the forensic medicine department for further evaluation and documentation of the judicial report. Examination of the medical files has revealed that the person applied to our and other hospitals with various symptoms simulating urologic, neurological, musculoskeletal, cardiovascular, and pulmonary disorders. The person had been hospitalized for extensive, costly, and often invasive medical examinations and/or treatment, and deceived the physicians into carry out unnecessary diagnostic procedures. No objective signs or evidence related to a work accident or stroke was obtained from the medical records. She has been followed up with the diagnosis of lymphangitis, thrombophlebitis and repeated cellulities since 2001, and the infection had been caused by intentional insertion of glass pieces into her left arm. The reason why she was unable to use her left arm was because of contraction related to the repeated soft tissue infection rather than the claimed work accident. This case was not only trying the medical personnel to make errors and confusion, but also attempting to mislead the judgment. Therefore, in forensic cases, medical history of patient must be evaluated carefully.

    A 7-month-old, male jaguar presented with dyspnea and leukocytosis unresponsive to antibiotic therapy. Radiographs revealed unilateral pulmonary consolidation. An exploratory thoracotomy was performed, and the left lung, which contained a large multilobular mass with extensive fibrosis and numerous caseonecrotic foci, was removed. Microscopically, eosinophilic granulomatous inflammation surrounded broad (4.4-8.3 microm) rarely septate hyphae. A diagnosis of Pythium insidiosum infection was confirmed by immunohistochemistry, immunoblot serology, culture, and polymerase chain reaction. Dyspnea recurred despite treatment, and the animal succumbed 3 weeks after surgery. Necropsy findings indicated that death resulted from occlusion of the right main stem bronchus by a fungal granuloma. The oomycete P. insidiosum typically causes granulomatous disease of the skin or gastrointestinal tract in animals and arteritis, keratitis, or cellulitis in humans. Infection is uncommon in felines, and pulmonary involvement is rare. This report details the first case of P. insidiosum infection in an exotic felid and provides the first description of primary pulmonary pythiosis in any species.

    Introduction: Foreign body injuries with date thorns, metal and wooden splinters are common in Middle East region, as most of it is desert. Some of the injuries lead to cellulitis or abscess formation, if neglected or improperly managed results in osteomyelitis or septic arthritis of foot structures. This is the first report of isolated navicular osteomyelitis following neglected foreign body in a paediatric foot. Case Report: A 10 year old male patient presented with discharging sinus in left mid-foot 3 years after penetrating injury with wooden splinter. The diagnosis of navicular osteomelitis is confirmed with plain radio-graphs. The ultrasound of foot was done to localize the foreign bodies. Patient was treated with complete removal of foreign body (wooden splinters), surgical debridement and combination of IV and oral cloxacillin for period of 6 weeks. At 18 months follow up, patient had painless foot with no recurrence or collapse of navicular bone. Conclusion: The neglected foreign body can result in osteomyelitis of small bones of foot in pediatric patient. The ultrasound is more useful tool in localizing foreign bodies; those are not radio-opaque. Early and prompt diagnosis with adequate treatment of established osteomyelitis by complete removal of foreign body, curettage and antibiotics can give good results. PMID:27298914

    The objective of the study was to evaluate the expression pattern of interleukin-6 (IL-6) to determine its utility in differentiating Castleman Disease subtypes and reactive lymphadenopathies. Paraffin-embedded tissue blocks from 20 cases referred for assessment of Castleman Disease (CD) and 4 cases of reactive hyperplasia were selected for immunohistochemical staining with an IL-6 antibody. Six pathologists evaluated the hematoxylin and eosin stained tissue sections and IL-6 expression pattern. Of 20 CD referral cases, the pathologic diagnosis was CD in 14 cases and included 6 hyaline-vascular (HV-CD), 6 plasma cell (PC-CD) and 2 "mixed type"-CD cases. The remaining 6 referral cases showed morphologic features consistent with reactive lymphadenopathy. Patients with non-CD, reactive lymphadenopathies had clinical and/or laboratory features of systemic lupus erythematosus, Hashimoto's disease, viral infection or chronic cellulitis. The pattern of IL-6 expression differed between CD subtypes and non-CD cases. In PC-CD, IL-6 expression was detected in plasma cells and vascular endothelial cells; whereas IL-6 immunoreactivity was detected primarily in vascular endothelial cells in HV-CD. Interfollicular plasma cells were prominent in PC-CD and reactive lymphadenopathies; however, IL-6 expression was significantly increased in PC-CD compared to reactive lymph nodes. Together with morphologic features, the expression pattern of IL-6 detected by immunohistochemistry is helpful to distinguish CD subtypes and reactive mimics. PMID:27650613

    Streptococcus pyogenes (group A Streptococcus) causes severe invasive infections including scarlet fever, pharyngitis (streptococcal sore throat), skin infections, necrotizing fasciitis (flesh-eating disease), septicemia, erysipelas, cellulitis, acute rheumatic fever, and toxic shock. The conversion from nonpathogenic to toxigenic strains of S. pyogenes is frequently mediated by bacteriophage infection. One of the key bacteriophage-encoded virulence factors is a putative "hyaluronidase," HylP1, a phage tail-fiber protein responsible for the digestion of the S. pyogenes hyaluronan capsule during phage infection. Here we demonstrate that HylP1 is a hyaluronate lyase. The 3D structure, at 1.8-angstroms resolution, reveals an unusual triple-stranded beta-helical structure and provides insight into the structural basis for phage tail assembly and the role of phage tail proteins in virulence. Unlike the triple-stranded beta-helix assemblies of the bacteriophage T4 injection machinery and the tailspike endosialidase of the Escherichia coli K1 bacteriophage K1F, HylP1 possesses three copies of the active center on the triple-helical fiber itself without the need for an accessory catalytic domain. The triple-stranded beta-helix is not simply a structural scaffold, as previously envisaged; it is harnessed to provide a 200-angstroms-long substrate-binding groove for the optimal reduction in hyaluronan viscosity to aid phage penetration of the capsule.

    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.

    The symptoms of Staphylococcal scalded skin syndrome (SSSS) include blistering of skin on superficial layers due to the exfoliative toxins released from Staphylococcus aureus. After the acute exfoliation of skin surface, erythematous cellulitis occurs. The SSSS may be confined to few blisters localized to the infection site and spread to severe exfoliation affecting complete body. The specific antibodies to exotoxins and increased clearence of exotoxins decrease the frequency of SSSS in adults. Immediate medication with parenteral anti-staphylococcal antibiotics is mandatory. Mostly, SSSS are resistant to penicillin. Penicillinase resistant synthetic penicillins such as Nafcillin or Oxacillin are prescribed as emergency treatment medicine. If Methicillin-resistant Staphylococcus aureus (MRSA) is suspected), antibiotics with MRSA coverage (e.g., Vancomycin or Linezolid) are indicated. Clindamycin is considered as drug of choice to stop the production of exotoxin from bacteria ribosome. The use of Ringer solution to to balance the fluid loss, followed by maintainence therapy with an objective to maintain the fluid loss from exfoliation of skin, application of Cotrimoxazole on topical surface are greatlly considered to treat the SSSS. The drugs that reduce renal function are avoided. Through this article, an attempt has been made to focus the source, etiology, mechanism, outbreaks, mechanism, clinical manisfestation, treatment and other detail of SSSS. PMID:27651848

    This paper describes design and development of a self-management program, delivered by telerehabilitation (TR), to address the problem of chronic lower limb swelling in persons with limited mobility. The 18.6 million persons with limited mobility in the USA are at increased risk for chronic lower limb swelling and related secondary complications, including cellulitis and skin ulcers. Over time, chronic swelling often progresses to lymphedema, an incurable condition requiring lifelong care. Without successful self-management, lymphedema and its related complications inevitably worsen. Access and adherence to appropriate treatment are challenging for persons with limited mobility. Program development involved a structured process to establish content validity (videos and manuals), readability, suitability, and selection of a TR platform to deliver the educational program. Our goal was to develop a program that would engage patients in self-management skills. The TR software platform chosen, Versatile and Integrated System for Telerehabilitation (VISYTER) was designed to facilitate face-to-face delivery of an interactive home-based self-management program via the internet in real time. Results demonstrated validity of the educational program and ease of use with TR. Future plans are to evaluate ability of this approach to promote self-management skills, home monitoring, and improved management of persons with lymphedema and limited mobility. PMID:23227323

    Thirty-one patients with juvenile nasopharyngeal angiofibroma treated at Memorial Sloan-Kettering Cancer Center from 1949 to 1979 were reviewed. Eighteen of the patients were previously untreated and in the other 13, previous treatment elsewhere had failed. Median follow-up was 54 months. All the patients were male adolescents whose presentations were characterized by epistaxis (73 percent) and nasal obstruction (60 percent). The tumors invariably arose within the nasal cavity or nasopharynx and involved neighboring structures in 58 percent of the patients. Treatment included surgery (30 patients), radiotherapy (13 patients), the administration of androgens (11 patients), sclerotherapy (2 patients), and cryotherapy (1 patient). Of the 18 primary patients, 14 were managed surgically with irradication of disease in 12 (86 percent). Of the four primary patients initially treated nonsurgically, disease recurred in three, all of whom were rendered free of disease by surgical excision. Of the 13 secondary patients, 8 were free of disease after surgery only, and 2 were free of disease after multimodal therapy with surgery being the last treatment employed. There were no deaths. Maxillary radionecrosis (one patient) and facial cellulitis (three patients) constituted the only significant morbidity. This study has demonstrated the clinical characteristics of juvenile nasopharyngeal angiofibroma and supports the primary role of surgical excision in its management.

    We were presented with two cases of relapsing polychondritis (RP) associated with different types of ocular inflammation. The first case was a 35-year-old man who had bilateral hyperemic conjunctiva and ocular pain, and was referred to Chiba University Hospital with a diagnosis of episcleritis refractory. He was treated with dexamethasone eye drops. He developed tinnitus, deafness in both ears, and left auriculitis. A left auricular biopsy showed an infiltration of lymphocytes surrounding the cartilage. He was diagnosed with RP and treated with 30 mg/day oral prednisolone. After tapering the prednisolone, the scleritis in both eyes improved. The second case was a 71-year-old man who was deaf in both ears and had bilateral scleritis. At the first visit to our hospital, his left eyelid and right auricula were reddish and swollen, and he reported some pain. He was treated with intravenous antibiotics, and the left orbital cellulitis quickly improved. However, he developed right scleritis and left gonitis. Magnetic resonance imaging showed bilateral posterior scleritis and right auricular perichondritis. Auricular biopsy showed an infiltration of lymphocytes into the periauricular tissue. He was diagnosed with RP, and 40 mg/day oral prednisolone was given and his symptoms improved. Although RP is rare, it is a life-threatening disease. Thus, ophthalmologists should consider RP in patients with both ocular and auricular inflammation. PMID:26425107

    Le syndrome de Vogt-Koyanagi-Harada (VKH) est une affection systémique rare, sévère mettant en jeu le pronostic visuel malgré les traitements agressifs, caractérisée par l'association de plusieurs symptômes: oculaires, méningés, auditifs et cutanés secondaire à une auto-immunisation où le mélanocyte serait la cellule cible. Nous rapportons un nouveau cas rare où l'atteinte oculaire est isolée. La sévérité de l'uvéite réside dans la fréquence des récidives, dans la cortico-résistance et dans la forte incidence des complications qui conditionnent le pronostic et expliquent les acuités visuelles finales médiocres. La prise en charge doit être précoce afin d'essayer d'améliorer le pronostic visuel. PMID:25667692

    Onychomycosis increases the risk of developing secondary bacterial infection and cellulitis if left untreated. The aim of this study was to determine the prevalence of onychomycosis among diabetics and its associated factors. A cross sectional study using universal sampling of all type 1 and 2 diabetic patients attending a primary care facility of the Universiti Kebangsaan Malaysia (UKM) from January to March 2011 was conducted. Samples were taken from clinically abnormal nails and from the first right toenail in the absence of nail abnormalities and cultured for fungal elements. A total of 151 diabetics participated in the study. The mean patient age was 60.7 +/- 9.1 years. A total of 123 nail samples (81.5%) were culture positive for fungal elements. A positive correlation was found between onychomycosis and increasing age (p = 0.011) and clinically abnormal nails (p < 0.05). There were no significant correlations with gender, ethnic group, duration of diabetes, types of diabetes or glycemic control. The prevalence of onychomycosis among diabetics in our study was high.

    Veno-occlusive disease (VOD) is a complication arising from the toxicity of conditioning regimens that have a significant impact on the survival of patients who undergo stem cell transplantation. There are several known risk factors for developing VOD and their assessment before the start of conditioning regimens could improve the quality of care. Equally important are early identification of signs and symptoms ascribable to VOD, rapid diagnosis, and timely adjustment of support therapy and treatment. Nurses have a fundamental role at the stages of assessment and monitoring for signs and symptoms; therefore, they should have documented skills and training. The literature defines nurses' areas of competence in managing VOD, but in the actual clinical practice, this is not so clear. Moreover, there is an intrinsic difficulty in managing VOD due to its rapid and often dramatic evolution, together with a lack of care tools to guide nurses. Through a complex evidence-based process, the Gruppo Italiano per il Trapianto di Midollo Osseo (GITMO), cellule staminali emopoietiche e terapia cellulare nursing board has developed an operational flowchart and a dynamic monitoring tool applicable to haematopoietic stem cell transplantation patients, whether they develop this complication or not.

    Information regarding analgesics in pinnipeds is limited. This study aimed to establish the pharmacokinetic parameters of a single subcutaneous dose of sustained release buprenorphine (Buprenorphine SR) in juvenile northern elephant seals (Mirounga angustirostris) with regard to its potential to provide long-lasting analgesia that requires infrequent dosing. Seals (n=26) were administered a single dose of sustained release buprenorphine at 0.12 mg/kg s.c. Blood samples were collected from the extradural intervertebral vein at 0 hr and at three or four of the following time points: 0.5, 1, 2, 6, 12, 24, 36, 48, 60, 96, 120, and 144 hr. Seals were examined daily for systemic and local adverse reactions. Plasma was analyzed by liquid chromatography tandem-mass spectrometry for buprenorphine and norbuprenorphine concentrations. A noncompartmental analysis for pharmacokinetic parameters was calculated using standard methods and equations. An average maximum concentration of 1.21 ng/ml (0.3-2.9 ng/ml) was detected 12 hr postadministration. Concentrations were quantifiable up to 144 hr postadministration but were below those expected to provide analgesia in some other species. No systemic adverse effects were noted in healthy seals receiving sustained release buprenorphine. Cellulitis or abscesses at the injection site were observed in 6/26 (23%) seals between 24 and 168 hr postadministration. Adverse local effects suggest that this drug should be used with caution in northern elephant seals. PMID:25831576

    Skin of color, also known as ethnic skin, is described as skin of individuals of African, Asian, Hispanic, Native-American, Middle Eastern, and Pacific Island backgrounds. Differences in hair morphology, hair grooming, cultural practices, and susceptibility to keloid scarring exist within these populations and have been implicated in hair, scalp, and skin disorders. Acne keloidalis (AK), central centrifugal cicatricial alopecia (CCCA), dissecting cellulitis of the scalp (DCS), pseudofolliculitis barbae (PFB), traction alopecia (TA), and keloids are the most prevalent follicular and scarring disorders in skin of color. They have been associated with disfigurement, permanent hair loss, emotional distress, and decreased quality of life. Hair grooming practices, such as the use of chemical relaxers, heat straightening, and tight braiding and weaving can cause scalp irritation and follicular damage and are linked to the pathogenesis of some of these conditions. Consequently, patient education and behavior modifications are integral to the prevention and management of these disorders. Scarring disorders are also of concern in ethnic populations. Keloid scarring is more prevalent in individuals of African, Asian, and Hispanic descent. The scarring alopecia CCCA is almost exclusively seen in patients of African descent. Therapeutic regimens such as intralesional corticosteroids, surgical excision, and laser therapy can be effective for these follicular and scarring disorders, but carry a risk of dyspigmentation and keloid scarring. Ethnic skin and hair may present unique challenges to the clinician, and knowledge of these differences is essential to providing quality care.

    Morganella morganii belongs to the tribe Proteeae of the Enterobacteriaceae family. This species is considered as an unusual opportunistic pathogen that mainly causes post-operative wound and urinary tract infections. However, certain clinical M. morganii isolates present resistance to multiple antibiotics by carrying various resistant genes (such as blaNDM-1, and qnrD1), thereby posing a serious challenge for clinical infection control. Moreover, virulence evolution makes M. morganii an important pathogen. Accumulated data have demonstrated that M. morganii can cause various infections, such as sepsis, abscess, purple urine bag syndrome, chorioamnionitis, and cellulitis. This bacterium often results in a high mortality rate in patients with some infections. M. morganii is considered as a non-negligent opportunistic pathogen because of the increased levels of resistance and virulence. In this review, we summarized the epidemiology of M. morganii, particularly on its resistance profile and resistant genes, as well as the disease spectrum and risk factors for its infection.

    Background: Snake bite envenomation is a major public health concern in developing countries. Acute kidney injury (AKI) is as important cause of mortality in patients with vasculotoxic snake bite. Aims: This study was to evaluate the clinical profile of snake bite patients and to determine the predictors of developing AKI following snake bite. Materials and Methods: Two hundred and eighty-one patients with snake envenomation were included. Eighty-seven patients developed AKI (Group A) and 194 (Group B) did not. History, examination findings and investigations results were recorded and compared between the two groups. Results: In group A, 61 (70.11%) patients were male and in group B, 117 (60.30%) patients were male. Out of 281 patients, 232 had cellulitis, 113 had bleeding tendencies, 87 had oliguria, 76 had neuroparalysis, and 23 had hypotension at presentation. After multivariate analysis, bite to hospital time (P = 0.016), hypotension (P = 0.000), albuminuria (P = 0.000), bleeding time (P = 0.000), prothrombin time (P = 0.000), hemoglobin (P = 0.000) and total bilirubin (P = 0.010) were significant independent predictors of AKI. Conclusions: AKI developed in 30.96% of patients with snake bite, leading to mortality in 39.08% patients. Factors associated with AKI are bite to hospital time, hypotension, albuminuria, prolonged bleeding time, prolonged prothrombin time, low hemoglobin and a high total bilirubin. PMID:24350071

    Gastric electrical stimulation can provide symptomatic relief for patients with refractory gastroparesis. Traditionally, these wires are placed through a midline laparotomy. This paper describes and illustrates, in detail, the laparoscopic technique for successful implantation. Thirty-one consecutive patients from October 2003 to March 2005 underwent laparoscopic insertion of gastric stimulating wires for gastroparesis. Twenty-six patients were female. Four laparoscopic ports were used to insert a pair of electrodes. Anterior, cephalad retraction of the gastric wall is critical for accurate seromuscular placement of gastric leads. Intraoperative endoscopy was used to verify the seromuscular placement of the leads. Both leads were secured to a subcutaneous generator and electrical parameters were immediately established in the operating room. Patient demographics, operative details, and postoperative morbidities were recorded. All procedures were completed laparoscopically. The mean operative time was 114.4 +/- 20.9 minutes (range, 95-140). No perioperative mortality occurred. Two patients developed cellulitis at the generator site postoperatively and oral antibiotics were prescribed for one week postoperatively. No hardware was removed. Two patients had their generators repositioned due to pain at the pocket site. Gastric electrical stimulation is a novel treatment modality for patients with refractory gastroparesis and can be accomplished safely via laparoscopy. Laparoscopic insertion is successful even in patients with prior surgery and intact gastrointestinal tubes. Long-term follow-up and the current prospective multicenter trial continue to assess the efficacy of this treatment modality. PMID:17362169

    Serratia marcescens is a species of gram negative bacillus, classified as a member of the Enterobacteriaceae, mainly involved in opportunistic infections, particulary in the hospital environment. Cutaneous infections have rarely reported in literature and are predominantly observed in elderly or in immunocompromised patients. The clinical manifestations of skin infections include granulomatous lesions, necrotizing fasciitis, nodules, cellulitis, ulcers, dermal abscesses. Infections caused by S. marcescens may be difficult to treat because of resistance to a variety of antibiotics, including ampicillin and first and second generation cephalosporins. Aminoglycosides have good activity against S. marcescens, but resistant strains have also been described. We report a very intriguing case of S. marcescens infection, in an immunocompetent 18-year-old man, causing multiple rounded ulcers of varying sizes, along with few pustular lesions that both clinically and histopathologically mimic a pyoderma gangrenosum (PG). This is a non infectious neutrophilic skin disorder, characterized by painful and rapidly progressing skin ulceration. According to our experience, we would strongly recommend to perform cultures of multiple skin ulcers resembling PG, even in young healthy patients, to ensure correct diagnosis and treatment, since resistant to conventional antibiotics bacteria such as S. marcescens may be the cause of these lesions, like in the case here reported.

    Onychomycosis is a difficult diagnosis to manage and treatment is sometimes avoided, as this diagnosis is often wrongly perceived as a cosmetic problem. However, onychomycosis has a negative impact on patients’ quality of life, affecting social interaction, psychological well-being, and physical activities. Onychomycosis is also a risk factor for patients with diabetes, with proven increased rates of cellulitis, gangrene, and foot ulcers. Treatments are only mild to moderately effective, and rates of relapse and reinfection are high. Oral treatments require laboratory monitoring due to risk of hepatotoxicity and may be contraindicated in some patients due to risk of drug–drug interactions. Topical treatments require prolonged application and are not very effective. Efinaconazole 10% solution is a new topical triazole treatment for mild to moderate distal subungual onychomycosis, with good efficacy and without the need for debridement of nails. In onychomycosis of the toenails, efinaconazole 10% solution is documented to have a statistically significant, positive impact on patient satisfaction and quality of life. PMID:26170638

    Skin rashes are infrequently encountered in the intensive care units, either as a result or as a cause of admission. The entities of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) form a spectrum of desquamating skin diseases that have multiple etiologies, the most common being drug-related reactions; very rarely, the cause may be cutaneous malignancies. We herein present a unique case of a 54-year-old male patient with psoriasis treated with methotrexate, who presented with a cellulitis-like clinical picture, then developed a severe progressive systemic inflammatory response syndrome, and progressed clinically to SJS, then TEN even after discontinuing the antibiotics and methotrexate. A skin biopsy demonstrated an aggressive and rapidly-progressing T-cell lymphoma. The present case highlights the necessity of skin biopsy when encountering SJS and TEN in the ICU in order to identify potentially treatable/controllable causes. Although it appeared reasonable to correlate TEN solely to medications, the skin biopsies clearly demonstrated an aggressive T-cell skin lymphoma. In a patient with a better general condition it may have been helpful to treat this malignancy. TEN is a life-threatening condition and skin biopsy is the cornerstone of diagnosis, despite the presence of multiple risk factors and the typical physical findings of a drug-induced reaction.

    Electrospinning of biopolymers has gained significant interest for the fabrication of fibrous mats for potential applications in tissue engineering, particularly for wound dressing and skin regeneration. In this study, for the first time, we report successful electrospinning of chitosan-based biopolymers containing bacterial cellulous (33 wt %) and medical grade nanodiamonds (MND) (3 nm; up to 3 wt %). Morphological studies by scanning electron microscopy showed that long and uniform fibers with controllable diameters from 80 to 170 nm were prepared. Introducing diamond nanoparticles facilitated the electrospinning process with a decrease in the size of fibers. Fourier transform infrared spectroscopy determined hydrogen bonding between the polymeric matrix and functional groups of MND. It was also found that beyond 1 wt % MND, percolation networks of nanoparticles were formed which affected the properties of the nanofibrous mats. Uniaxial tensile testing of the woven mats determined significant enhancement of the strength (from 13 MPa to 25 MP) by dispersion of 1 wt % MND. The hydrophilicity of the mats was also remarkably improved, which was favorable for cell attachment. The water vapor permeability was tailorable in the range of 342 to 423 µg·Pa(-1)·s(-1)·m(-1). The nanodiamond-modified mats are potentially suitable for wound healing applications. PMID:27399726

    Over the last few years, the number of associations involved in AIDS prevention has dramatically increased in Ivory Coast, especially in Abidjan. This article describes an experiment in the prevention of AIDS and STDs among young people in Abidjan by means of peer education. It follows the management and progress of a youth organization for AIDS prevention, CESAM (Cellule Scolaire Anti-SIDA et MST), the School-based Anti-AIDS and STD Unit. Critical review of the activities of this association identifies a number of methodological, planning, human and material problems, which have received little attention in the past. CESAM is one of the first anti-AIDS associations in Ivory Coast to target young people and to have young members. This may be the reason for some of its successes and some of its failures and disappointments. The association's successes include the provision of information to more than 25,000 people between 1992 and 1996, and the overall satisfaction of the public and local AIDS institutions. The young people involved have taken on a new social identity, which has developed from the motivation of association members and the personal experiences of some with respect to AIDS, STDs and problems associated with contraception. However, this new identity is threatened by rivalry between members and the search for funding, as the substantial funding obtained in 1994-1995 can show it. PMID:10623875

    Onychomycosis increases the risk of developing secondary bacterial infection and cellulitis if left untreated. The aim of this study was to determine the prevalence of onychomycosis among diabetics and its associated factors. A cross sectional study using universal sampling of all type 1 and 2 diabetic patients attending a primary care facility of the Universiti Kebangsaan Malaysia (UKM) from January to March 2011 was conducted. Samples were taken from clinically abnormal nails and from the first right toenail in the absence of nail abnormalities and cultured for fungal elements. A total of 151 diabetics participated in the study. The mean patient age was 60.7 +/- 9.1 years. A total of 123 nail samples (81.5%) were culture positive for fungal elements. A positive correlation was found between onychomycosis and increasing age (p = 0.011) and clinically abnormal nails (p < 0.05). There were no significant correlations with gender, ethnic group, duration of diabetes, types of diabetes or glycemic control. The prevalence of onychomycosis among diabetics in our study was high.

    Even though community-acquired methicillin resistant Staphylococcus aureus (CA-MRSA) was described a decade ago, reports from Brazil are scarce and cases occurred in large urban centers. We report MRSA sepsis in a 16-year-old male from a small town and who had no history of exposure to healthcare or recent travel. After trauma during a soccer match, he presented swelling in the right thigh, which evolved in a month to cellulitis complicated by local abscess, orchitis and pneumonia. The patient presented severe sepsis, with fever and respiratory failure. Laboratory findings included blood leukocyte counts above 40,000/mm(3) and thrombocytopenia. He was submitted to mechanical ventilation and therapy with vancomycin and imipenem. He had a slow but favorable response to therapy and was discharged after six weeks of hospitalization. MRSA grew from blood cultures and respiratory aspirates obtained before antimicrobial therapy. The isolate belonged to sequence type 5, spa type t311, harbored SCCmec type IV and genes for Panton-Valentine leukocidin and Enterotoxin A. The pulsed-field gel electrophoresis pattern was distinct from North American classic CA-MRSA clones. However, the sequence type and the spa type revealed that the clone belong to the same clonal complex isolated in Argentina. This is the first CA-MRSA infection reported in that region, with significant epidemiologic and clinical implications.

    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.

    Background The aim of this study was to compare the days of hospitalization length between patients treated with Moxifloxacin with that of patients treated with a Clindamycin/Ceftriaxone combination and additionally, to isolate and identify the oral pathogens involved in orofacial odontogenic infections. Material and Methods A pilot-controlled-clinical-trial was carried out on hospitalized patients with cervicofacial odontogenic abscesses or cellulitis, who were randomly asigned to two study groups: 1) patients who received Moxifloxacin, and 2) patients receiving Clindamycin/Ceftriaxone combination. Infiltrate samples were collected through transdermic or transmucosal punction and later cultured on a media specific for aerobic and anaerobic microorganisms. Mean hospitalization duration in days until hospital discharge and susceptibility assessment in rates were established. Results Mean hospitalization time in days of patients treated with Moxifloxacin was 7.0 ± 1.6 days, while in the Clindamycin/Ceftriaxone group, this was 8.4 ± 1.8 days, although significant difference could not be demonstrated (p=0.074). A total of 43 strains were isolated, all of these Gram-positive. These strains appeared to be highly sensitive to Moxifloxacin (97.5%) and Ceftriaxone (92.5%). Conclusions Moxifloxacin and Ceftriaxone appear to be potential convenient and rational alternatives to traditional antibiotics, for treating severe odontogenic infections, in conjunction with surgical extraoral incision, debridement, and drainage. Key words:Orofacial odontogenic infections, antimicrobial susceptibility, antimicrobial resistance. PMID:26644841

    Information regarding analgesics in pinnipeds is limited. This study aimed to establish the pharmacokinetic parameters of a single subcutaneous dose of sustained release buprenorphine (Buprenorphine SR) in juvenile northern elephant seals (Mirounga angustirostris) with regard to its potential to provide long-lasting analgesia that requires infrequent dosing. Seals (n=26) were administered a single dose of sustained release buprenorphine at 0.12 mg/kg s.c. Blood samples were collected from the extradural intervertebral vein at 0 hr and at three or four of the following time points: 0.5, 1, 2, 6, 12, 24, 36, 48, 60, 96, 120, and 144 hr. Seals were examined daily for systemic and local adverse reactions. Plasma was analyzed by liquid chromatography tandem-mass spectrometry for buprenorphine and norbuprenorphine concentrations. A noncompartmental analysis for pharmacokinetic parameters was calculated using standard methods and equations. An average maximum concentration of 1.21 ng/ml (0.3-2.9 ng/ml) was detected 12 hr postadministration. Concentrations were quantifiable up to 144 hr postadministration but were below those expected to provide analgesia in some other species. No systemic adverse effects were noted in healthy seals receiving sustained release buprenorphine. Cellulitis or abscesses at the injection site were observed in 6/26 (23%) seals between 24 and 168 hr postadministration. Adverse local effects suggest that this drug should be used with caution in northern elephant seals.

    On 30 June 1559, Henry II, King of France, was mortally wounded in the head by a lance during a jousting match. Despite the best efforts of his physicians, Ambroise Paré and Andreas Vesalius, King Henry died 11 days later. This article, based on previously unpublished evidence, aims at examining the historical account of his death against modern medical practice to establish the probable cause of the king's death. We also discuss what treatments the doctors in the sixteenth century may have had to offer. Historical accounts of the joust provide details of the incident including the position of the visor of the king's helmet. Descriptions of the wood fragments removed from the right orbit by Italian observers and a new translation of the autopsy by Andreas Vesalius allow an accurate description of the actual injury. Our research counters previous theories and concludes that Henry II was the victim of craniofacial trauma involving the right eye and that he died from periorbital cellulitis caused by a retained foreign body in the wound, complicated by a left interhemispheric empyema preceded by a traumatic interhemispheric haematoma. It would appear that the royal court doctors advocated a wait-and-see strategy, with little actual input from Ambroise Paré or Andreas Vesalius, with a clearly regrettable outcome.
