    Peristomal pyoderma gangrenosum (PPG) is a rare subtype of pyoderma gangrenosum that is difficult to diagnose and treat. It is characterized by the rapid progression of painful necrotic ulcer surrounding an area of abdominal stoma. It is almost exclusively associated with inflammatory bowel disease even after bowel surgery and is associated with significant morbidity. Diagnosis of pyoderma gangrenosum is based on exclusion of other disorders replicating some of its clinical features and histo...

    Full Text Available Pyoderma gangrenosum (PG is an uncommon inflammatory ulcerative skin disease. It is characterized by painful progressive necrosis of the wound margins. Rarely, postoperative pyoderma gangrenosum (PPG manifests as a severe disturbance of wound healing following surgical interventions. Only rare cases of this complication have been reported after appendectomy. We report a case of PPG in a 29-year-old female after appendectomy. She was successfully treated with oral prednisolone. Postoperative pyoderma gangrenosum should be kept in mind in the differential diagnosis of any postoperative delayed wound healing, because this disease is simply distinguished from a postoperative wound.

    Peristomal pyoderma gangrenosum (PPG) is a rare subtype of pyoderma gangrenosum that is difficult to diagnose and treat. It is characterized by the rapid progression of painful necrotic ulcer surrounding an area of abdominal stoma. It is almost exclusively associated with inflammatory bowel disease even after bowel surgery and is associated with significant morbidity. Diagnosis of pyoderma gangrenosum is based on exclusion of other disorders replicating some of its clinical features and histopathological evidence. This is a case report of a 56-year-old lady with rheumatoid arthritis who presented with rapidly progressing abdominal ulcer 8 months after a Hartmanns procedure for perforated diverticulitis. The ulcer had formed a large cavity causing faecal filling in the dependent defect. The other causes of ulcer were excluded with negative histopathology, negative polymerase chain reaction for Mycobacterium ulcerans and negative acid fast bacillus (AFB) test. She was diagnosed with PPG which is routinely treated medically due to risk of setting off a second focus of pyoderma if surgically intervened. However due to increased risk of faecal peritonitis, it was decided to proceed with surgical debridement. This article will discuss the case in more detail and briefly discuss diagnosis and treatment options for PPG. PMID:27302499

    2012-02-01

    A 65-year-old woman presented with widespread necrotising cutaneous ulceration and oral involvement. Past history included rheumatoid arthritis, and a left nephrectomy.Examination revealed multiple violaceous undermined ulcers. Blood investigations showed an acute inflammatory response. Skin histopathology showed epidermal ulceration with acute and chronic inflammation. Direct immunofluorescence was negative. A diagnosis of pyoderma gangrenosum with oral involvement was made. Mycophenolate mofetil therapy resulted in complete resolution of her pyoderma gangrenosum. Her treatment was complicated by a left proteus mirabilis psoas abscess. This resolved following four weeks of antibiotics.Pyoderma gangrenosum with oral involvement is rare but has been linked with inflammatory bowel disease and hematological disorders. Oral pyoderma gangrenosum has not previously been described in rheumatoid arthritis. Primary psoas abscess is rare but can develop in immunocompromised patients. Proteus mirabilis has been reported in patients years after nephrectomy. This is a rare case of pyoderma gangrenosum with oral involvement.

    Full Text Available Pyoderma gangrenosum is one of the most severe complications that can occur following stoma placement. Despite few cases reported in the literature, it is considered an underdiagnosed entity. We present a case of peri-ileostomy pyoderma gangrenosum (PPG in a patient who underwent a pancoloproctectomy and permanent ileostomy due to ulcerative colitis (UC. Treatment was based on local cures, proper fitting of ostomy devices, topical tacrolimus and systemic corticosteroids, adalimumab and antibiotics. Satisfactory resolution was achieved in eight weeks.

    Full Text Available Background. Atypical forms of pyoderma gangrenosum generally appear on the upper extremities; most frequently they are associated with myeloproliferative disorders, including osteomyelofibrosis. A response to systemic steroids is more pronounced than in classical form. Sometimes it may be the first sign of an underlying malignancy. Case report. We reported a patient with atypical pyoderma gangrenosum developed during the course of a myeloid malignancy - osteomyelofibrosis. The lesions occurred after a minor trauma. Painful blistering plaques, with an elevated, bluish-gray border were located on the dorsal aspect of hands. No skin malignancy was found. The lesions resolved rapidly to systemic steroids. Conclusion. Considering the unusual clinical presentation which makes the diagnosis difficult, as well as the fact that atypical forms of pyoderma gangrenosum can be the first sign of malignancies, especially myeloproliferative ones, recognizing this entity enables timely guiding future investigations toward their prompt detection.

    Full Text Available Introduction: The cocaine is obtained from the leaves of the coca (Erythroxylon coca. It can be used in many ways, but the most common is the drug inhalation. The Cocaine also causes vasoconstriction at nasal mucous membrane and its chronic use can cause necrosis and nasal septum perforation. Pyoderma gangrenosum is an uncommon idiopathic disease characterized by ulcerations, usually observed on the legs. Its diagnosis is most common an exclusion of others diseases. So far, there is no specific treatment based on evidence by randomized controlled trials. Objective: Describe the rare association between Pyoderma gangrenosum and cocaine. Case Report: E. A., 27-year-old woman with destruction of nasal septum and palate who has been using a big amount of cocaine, been necessary note the difference from which disease cause de damage. Final Comments: Also there are only three cases of Pyoderma gangrenosum complicated with nasal septum perforation in cocaine users.

  10. Delayed diagnosis of post-surgical pyoderma gangrenosum: A multicenter case series and review of literature

    Rawaa Almukhtar

    Full Text Available Introduction: Pyoderma gangrenosum is a chronic neutrophilic dermatosis which can occur following trauma or surgery and can mimic infection. Surgical intervention can lead to progression of disease. Presentation of cases: This case series describes 3 cases of post-surgical pyoderma gangrenosum with delayed diagnosis from two large medical centers. Discussion: Epidemiology, pathogenesis, clinical and histopathologic presentation, and management of post-surgical pyoderma gangrenosum are discussed with a review of the literature. Conclusion: Post-surgical pyoderma gangrenosum (PSPG can mimic ulcerative disorders including bacterial infection. The diagnosis should be suspected in post-operative wounds with negative bacterial cultures which progress despite broad-spectrum antibiotics and surgical debridement. Recognizing the clinical features of PSPG is fundamental to prevent severe destruction and deformity. Keywords: Post-surgical, Pyoderma gangrenosum, Necrotizing fasciitis, Case report

    A 52-year-old woman with ulcerative colitis was admitted to our hospital for an ulcerative colitis flare-up under salazosulfapyridine therapy. The symptoms improved with high-dose corticosteroids. After prednisolone was tapered to 10 mg, the frequency of diarrhea increased. The diarrhea was accompanied by joint pain and a skin ulcer with abscess formation, which was diagnosed to be pyoderma gangrenosum. The patient was started on adalimumab. A positive response to the adalimumab therapy was observed after 2 weeks, during which time the ulcerative skin lesion healed completely, however, colonic mucosal healing was achieved at 2 months. Therefore, adalimumab appears to be an effective therapeutic option for patients with ulcerative colitis-associated pyoderma gangrenosum.

    Pyoderma gangrenosum (PG) is rare in infants. There have been 12 cases of PG in infants (<12 months old) reported in the past 25 years, to our knowledge. Six of these cases have been successfully controlled with systemic steroids, and one case with topical steroids alone. We report a case of an 8-month-old infant whose PG was aggressive and unresponsive to systemic steroids. Adjuvant treatment with cyclosporine was required to achieve healing. We review the previous cases of infantile PG and the therapeutic options in this age group.

    Full Text Available Pyoderma gangrenosum is a phenomenon of cutaneous ulceration where etiology is not well understood. About half of the cases have an associated extracutanoeus manifestation or associated systemic diseases. Most commonly associated systemic disorders include inflammatory bowel disease, hematologic malignancies, autoimmune arthritis, and vasculitis. We are reporting a case where pyoderma gangrenosum has presenting features for ulcerative colitis.

    Pyoderma gangrenosum is an inflammatory neutrophilic dermatosis. Current knowledge of this rare disease is limited owing to a lack of validated diagnostic criteria and large population studies. To evaluate the association of age with the clinical presentation and comorbidities of pyoderma gangrenosum. This was a multicenter retrospective cohort study performed at tertiary academic referral centers in urban settings. Adults (≥18 years) who were evaluated and diagnosed as having pyoderma gangrenosum at the Brigham and Women's and Massachusetts General Hospitals from 2000 to 2015 and the University of Pennsylvania Health System from 2006 to 2016 were included. Patient demographics, clinical features, medical comorbidities, and treatment. Of the 356 validated cases of pyoderma gangrenosum included in the study, 267 (75%) were women and 284 (84.8%) were white. The mean (SD) age at presentation was 51.6 (17.7) years. Pathergy was recorded in 100 patients (28.1%). A total of 238 patients (66.9%) had associated medical comorbidities: inflammatory bowel disease in 146 patients (41.0%); inflammatory arthritis in 73 patients (20.5%); solid organ malignant neoplasms in 23 patients (6.5%); hematologic malignant neoplasms in 21 patients (5.9%); and hematologic disorders, specifically monoclonal gammopathy of undetermined significance, myelodysplastic syndrome, and polycythemia vera in 17 patients (4.8%). When stratified by age, pathergy was more common in patients 65 years or older (36.3% vs 24.3%; P = .02). Inflammatory bowel disease was the only medical comorbidity that was more common in patients younger than 65 years (47.7% vs 26.6%; P clinical presentation in this large cohort was similar between different age groups, disease associations varied by age. The findings of this study may allow for a more focused, age-specific evaluation of patients with pyoderma gangrenosum.

    Behçet's syndrome (BS) is a rare multisystem disorder belonging to a group of neutrophilic dermatoses. We report a 65-year-old male patient who had suffered from recurrent painful orogenital ulcers for 50 years from the age of 15 and started developing pustular and bullous lesions evolving into non-healing ulcers similar to those seen in pyoderma gangrenosum (PG) two months prior to presenting to us. There was no evidence of systemic disease or malignancy. Routine baseline investigations were within normal limits. The patient was treated successfully with dapsone, antibiotics, and local wound care.

    We present a patient with atypical pyoderma gangrenosum (APG), which involved the patient's arm and hand. Hemorrhagic bullae and progressive ulcerations were initially thought to be secondary to an infectious process, but a biopsy revealed PG. Awareness of APG by infectious disease services may prevent unnecessary use of broad-spectrum antibiotics.

    Pyoderma gangrenosum (PG) manifests as recurrent deep ulceration of the skin and PG is associated with a variety of disorders. Approximately 30% of the cases of PG develop in patients with inflammatory bowel disease. A 34-year-old woman presented with a one-week history of recurrent ulcers on the right cheek and back. She was diagnosed with ulcerative colitis (UC) 4 years previously and with PG 1 year previously. The clinical course of the skin lesions followed the status of her UC. The patie...

  18. Pyoderma gangrenosum as a initial manifestation of ulcerative proctocolitis

    2011-09-01

    Full Text Available pyoderma gangrenosum is a rare inflammatory skin condition characterized by progressive and recurrent skin ulceration of destructive course. It is usually associated with rheumatoid arthritis, paraproteinemia, myeloproliferative diseases and inflammatory bowel diseases, especially non-specific ulcerative proctocolitis. In these situations, skin lesions are described as concurrent with the intestinal condition. However, reports on pyoderma gangrenosum preceding intestinal findings are less frequent. The authors describe a case of a woman with febrile condition associated with skin lesions diagnosed by biopsy as pyoderma gangrenosum. Two weeks later, she developed diarrhea, arthralgia and sepsis, being diagnosed as ulcerative proctocolitis. After the administration of the treatment for ulcerative proctocolitis, she showed improvements in sepsis care, remission of diarrhea and regression of skin lesions. This case highlights the importance of considering pyoderma gangrenosum as a manifestation associated with inflammatory bowel disease, regardless of its timing in relation to intestinal symptoms.Pioderma gangrenoso é uma forma de inflamação cutânea, caracterizada por ulceração progressiva e recorrente da pele, com curso destrutivo. Geralmente é associada à artrite reumatoide, paraproteinemia, doenças mieloproliferativas e doença inflamatória intestinal, em especial retocolite ulcerativa inespecífica. Em tais casos, as lesões cutâneas são descritas concomitantes ao quadro intestinal, porém, relatos com descrição de pioderma gangrenoso precedendo achados intestinais são menos frequentes. Os autores relatam caso de mulher com quadro febril associado a lesões cutâneas diagnosticadas por biópsia como pioderma gangrenoso. Duas semanas depois, apresentou diarreia, artralgia e sepse sendo diagnosticada retocolite ulcerativa. Com o tratamento para retocolite ulcerativa apresentou melhora do quadro séptico, remissão da diarreia e

    We present a unique case of a 36-year-old male who developed more than 20 pyoderma gangrenosum (PG) ulcers showing on histopathology a dense inflammatory infiltrate composed of histiocytoid mononuclear immature cells with a strong positivity for myeloperoxidase and Leder stain, suggesting a myeloid lineage in the absence of a concomitant myeloproliferative disorder. Histiocytoid Sweet syndrome (SS) is now recognized as a histological subtype of SS. Although PG and SS belong to the spectrum of neutrophilic diseases, to the best of our knowledge, this is the first case of a "Histiocytoid pyoderma gangrenosum" encompassing immature granulocytes in the absence of leukemia cutis. © 2017 John Wiley & Sons A/S.

    This report describes a case of neutrophilic dermatosis in a dog, with a number of clinical and pathological similarities to human pyoderma gangrenosum. A seven-year-old, female German shepherd dog with a history of non-erosive idiopathic polyarthritis was presented with severe facial swelling, bilateral erosivoulcerative lesions on the muzzle and multiple, eroded, dermal-subcutaneous nodules on the cranial trunk. Histopathological examination of skin biopsies revealed a necrotising neutrophilic dermatitis. No infectious agents could be detected using specific stains, immunohistochemistry, serology and bacterial aerobic, anaerobic or fungal cultures. A sterile neutrophilic dermatosis resembling human pyoderma gangrenosum was presumptively diagnosed, and the patient showed an excellent response to treatment with prednisone and ciclosporin.

    Full Text Available Classic type of pyoderma gangrenosum (PG is an uncommon ulceronecrotic cutaneous disease of uncertain aetiology characterised by broad zones of confluent ulceration with violaceous undermined margins. Some 50% of cases are associated with systemic diseases. The superficial granulomatous variant of pyoderma gangrenosum (SGPG of the external genitalia is extremely rare Patients with this condition develop single or multiple ulcerated skin lesions often with sinus tract formation. The majority of these lesions were found on the trunk and limbs. SGPG is less likely to be associated with underlying disease processes than classic PG. We present a 58 year-old with recalcitrant penile ulceration demonstrated to be SGPG on biopsy. Although rare and poorly recognised, the histological features are sufficiently typical to allow the correct diagnosis to be established.

    A 76-year-old man complained of difficulty in urination and miction pain with abacterial pyuria after radiation therapy for prostate cancer. Transurethral resection of the prostate was performed and histopathologically widespread necrosis was observed in the prostate. Thereafter retention of urine and fever occurred and computed tomography scan revealed an abscess of the penile corpus. The abscess was drained, but the fever continued. He developed an abacterial lung abscess and abacterial necrotic ulcerating lesions on his back, his left leg and his lower abdomen. Macroscopic findings demonstrated typical features of pyoderma gangrenosum. Steroid treatment was initiated and the response to steroid therapy was dramatic. Finally urinary diversion using an ileal conduit was performed. We found few cases of pyoderma gangrenosum involving lesions other than those of the skin in the literature. This is the first report of pyoderma gangrenosum involving the prostate gland after radiation therapy for prostate cancer. (author)

    1990-12-01

    Full Text Available A 35-year-old female with pyoderma gangrenosum developed paraparesis with a sensory level at L1. Three months later she complained of diplopia and was found to have bilateral internuclear ophthalmoplegia with exotropia and no ocular convergence. The term Webino syndrome has been coined to design this set of neuro-opthalmologic findings. Although it was initially attributed to lesions affecting the medial longitudinal fasciculus and the medial rectus subnuclei of the oculomotor complex in the midbrain the exact location of the lesion is still disputed. In the present case both myelopathy and Webino syndrome were probably due to vascular occlusive disease resulting from central nervous system vasculitis occurring in concomitance to pyoderma gangrenosum.

    Full Text Available Pyoderma gangrenosum (PG is a rare disease and that affecting specifically the sole of the foot, is even rarer. Here, we report the case of a 54-year-old female admitted with a painful ulcer on the sole of the right foot which was initially treated with empirical antibiotics and debridement. The disease was found to spread rapidly after each debridement. The culture reports were negative; rheumatology workup and Doppler study were within normal limits. A clinical suspicion of PG was made and was confirmed with tissue biopsy. She was started on oral steroids following which she dramatically improved. Thus, when a patient presents with a rapidly expanding painful ulcer in a vascular limb that is refractory to antibiotic treatment and exacerbating on debridement, it is imperative to consider the possibility of PG.

    Here, we report a case of pyoderma gangrenosum of the penis which was difficult to distinguish from Fournier gangrene. The patient was a 54-year-old male who was aware of redness and swelling of the glanspenis for 1 month prior to a consultation at our department. Although he was diagnosed with herpes and treated at a nearby hospital, his symptoms did not improve. Subsequently, the patient visited our department following the onset of pain and fever. During his initial consultation, he had a fever of 39 °C as well as redness and swelling of the glans penis with partial spontaneous purulent discharge. His blood test revealed an elevated white blood cell count (20, 000/μl) and C-reactive protein (19.1 mg/dl). Because Fournier gangrene was suspected, administration of broad-spectrum antimicrobial agents was initiated but proved to be ineffective. An abscess (2 cm in diameter) was also noted in the umbilical region.Enterococcus faecalis was detected by the bacterial culture ; and therefore, Fournier gangrene was diagnosed. A partial penectomy was performed to control the infection. Pathological findings showed only non-specific inflammation ; however, fever persisted postoperatively and blood test results showed no improvement. Furthermore, new abscess lesions emerged on the right heel and back. Because the re-performed abscess bacterial culture test result was negative, pyoderma gangrenosum was suspected, and he was started on oral prednisolone (20 mg/day). On the following day, his fever subsided and his blood test results also showed improvement. A final diagnosis of pyoderma gangrenosum was ultimately made.

    2015-01-01

    Peristomal pyoderma gangrenosum (PPG) is a rare subtype of pyoderma gangrenosum that is characterized by painful, necrotic ulcerations occurring in the area surrounding an abdominal stoma. PPG is typically seen in younger patients with active inflammatory bowel disease. The etiology and pathogenesis is largely unknown and risk factors are not well defined. Therapy typically involves a combination of aggressive local wound care and systemic medications. Diagnosis and management of PPG can be difficult and data on treatment are limited. We present a case of severe postoperative peristomal recalcitrant to conventional therapy successfully treated with intravenous immune globulin. PMID:25802252

    2012-03-01

    PAPA syndrome is a recently identified hereditary autoinflammatory syndrome clinically characterized by pyogenic arthritis, severe acne, and pyoderma gangrenosum. It is caused by mutations in the PSTPIP1 gene and may be closely linked to the aseptic abscesses syndrome, which has been shown to be associated with CCTG repeat amplification in the promoter region of PSTPIP1. We describe two unrelated patients with a clinical presentation quite similar to, yet distinct from, PAPA syndrome. Both patients had pyoderma gangrenosum and acute or remittent acne conglobata, but, in contrast to PAPA syndrome, lacked any episodes of pyogenic arthritis. Instead, they had suppurative hidradenitis. Mutations in PSTPIP1 exons 1 to 15 were excluded. In the promoter region, an increased repetition of the CCTG microsatellite motif was present on one allele in both patients. Alterations of the most commonly affected exons of the MEFV, NLRP3, and TNFRSF1A genes also were not detectable. One patient was treated with the interleukin (IL)-1 receptor antagonist anakinra and responded well, although without complete remission. This implies that IL-1ß may be of pathogenetic importance. Small number of patients, no gene mutation identified, and unclear efficacy of therapy are limitations. The clinical triad of pyoderma gangrenosum, acne, and suppurative hidradenitis represents a new disease entity within the spectrum of autoinflammatory syndromes, similar to PAPA and aseptic abscesses syndrome. For this disease, we propose the acronym "PASH" syndrome. PASH syndrome may respond to IL-1ß blockade. Copyright © 2011 American Academy of Dermatology, Inc. Published by Mosby, Inc.

    Autoinflammatory disorders are a group of Mendelian disorders characterized by seemingly unprovoked inflammatory bouts without high-titer autoantibodies or antigen-specific T-cells and are probably due to defects in the innate immunity. We here report on a 4-year-old Arabic boy with the clinical presentation of an autoinflammatory disorder, namely Pyogenic Arthritis, Pyoderma Gangrenosum and Acne (PAPA) syndrome. The presentation includes abscess formation after immunization and recurrent mono-articular acute arthritis in various joints that responded favourably to systemic glucocorticosteroids, albeit without acne or pyoderma gangrenosum. The mutation analysis of the boy identified a novel de novo mutation in PSTPIP1, the gene responsible for PAPA syndrome. We recommend that the diagnosis of PAPA syndrome should be entertained in the differential diagnosis of patients with recurrent sterile pyogenic arthritis prior to the development of pyoderma gangrenosum or acne in order to initiate a timely management of the disorder.

    Pyoderma gangrenosum (PG) is an immune-mediated inflammatory skin condition representing one of the most distinct extraintestinal manifestations of inflammatory bowel disease (IBD). PG occurs independently from intestinal disease activity in about 1–2% of patients suffering from ulcerative colitis or Crohn's disease and is characterized by chronic deep skin ulcers whose exact pathogenesis is still unknown. So far, patients with ulcerative colitis have only been reported to develop PG during t...

    We report successful treatment of a refractory myelodysplastic syndrome-associated pyoderma gangrenosum with the combination of thalidomide and interferon-alpha2a in a single patient. A non-healing wound developed on a 40-year-old woman's left thumb after minor trauma. Massive ulcerovegetative lesions developed after reconstruction surgery. Histopathological examination of the bone marrow and cytogenetic studies revealed an atypical myeloproliferative/myelodysplastic syndrome. The skin lesions resolved dramatically after two months of thalidomide and interferon-alpha2a combination therapy and the haematological status improved.

    Pyoderma gangrenosum (PG) manifests as recurrent deep ulceration of the skin and PG is associated with a variety of disorders. Approximately 30% of the cases of PG develop in patients with inflammatory bowel disease. A 34-year-old woman presented with a one-week history of recurrent ulcers on the right cheek and back. She was diagnosed with ulcerative colitis (UC) 4 years previously and with PG 1 year previously. The clinical course of the skin lesions followed the status of her UC. The patient's skin lesions and bowel symptoms were not improved with prednisolone. After she was started on mesalazine, we observed rapid resolution of skin lesions and bowel symptoms. Herein, we report a case of recurrent PG with UC, and we discuss the possible association between these two conditions, and the efficacy of mesalazine therapy for the treatment of PG combined with UC.

    Pyoderma gangrenosum (PG) is an uncommon ulcerative disease of the skin. The cause is unknown but the condition is often associated with other diseases such as rheumatoid arthritis, ulcerative colitis, Crohn's disease or monoclonal gammopathy. The association between PG and haematological malignancies (acute leukaemia, Myeloproliferative disorders) is infrequent. Two cases of PG associated with haemopathy are described; one had primary thrombocythaemia and the other, acute myeloblastic leukaemia following for myeloma. The significance of this association is discussed in the light of other observations previously reported in the literature.

    Pyoderma gangrenosum (PG) is an uncommon extra-intestinal manifestation of inflammatory bowel disease (IBD). Despite limited published literature, biologics have caused a paradigm shift in the management of this difficult-to-treat skin condition. The clinical data and outcomes of three patients with active ulcerative colitis and concurrent PG treated with biologics (infliximab two and adalimumab one) are reviewed in this report. Biologics were added because of the sub-optimal response of the colonic symptoms and skin lesions to parenteral hydrocortisone therapy. All three patients showed a dramatic response to the addition of the biologics. In view of the rapid healing of the skin lesions, superior response rate, and the additional benefit of improvement in the underlying colonic disease following treatment, anti-tumor necrosis factor blockers should be considered as a first line therapy in the management of PG with underlying IBD.

    Full Text Available A patient with post-Cesarean wound complication was treated for necrotizing fasciitis (NF with sharp debridement and broad-spectrum antibiotics. Several operations and three weeks later, her abdominal skin, subcutaneous fat, right-sided rectus abdominus, and underlying fascia had been removed without any improvement in granulation tissue. Original pathology samples demonstrated sheets of necrosis consistent with NF, but were re-reviewed by a dermatopathologist who diagnosed the patient with pyoderma gangrenosum (PG. She was started on high-dose steroids and dapsone, and her wound quickly showed signs of improvement. Anchor bias delayed the initiation of steroids and diagnosis of PG as the surgical, medical, and consulting teams were hesitant to stray from the diagnosis of NF.

    To describe the genotypes, phenotypes, immunophenotypes, and treatments of PAPA syndrome (pyogenic sterile arthritis, pyoderma gangrenosum, and acne), a rare autoinflammatory disease, in 5 patients. Clinical information was gathered from medical records and through interviews with 5 patients from 4 kindreds. PSTPIP1 (CD2BP1) exon 10 and exon 11 sequencing was performed in each patient. Neutrophil granule content and cytokine levels were determined in plasma and stimulated peripheral blood mononuclear cells (PBMCs) from patients and controls. We identified 2 previously described PAPA syndrome-associated PSTPIP1 mutations, A230T and E250Q, and a novel change, E250K. Disease penetrance was incomplete, with variable expressivity. The cutaneous manifestations included pathergy, cystic acne, and pyoderma gangrenosum. Interleukin-1β (IL-1β) and circulating neutrophil granule enzyme levels were markedly elevated in patients compared to those in controls. PBMC stimulation studies demonstrated impaired production of IL-10 and enhanced production of granulocyte-macrophage colony-stimulating factor. Good resolution of pyoderma gangrenosum was achieved in 3 patients with tumor necrosis factor α (TNFα) blockade treatment. This analysis of 5 patients demonstrates that mutations in PSTPIP1 are incompletely penetrant and variably expressed in the PAPA syndrome. Neutrophil granule proteins are markedly elevated ex vivo and in the plasma, and elevated levels might be compatible with a diagnosis of PAPA syndrome. TNFα blockade appears to be effective in treating the cutaneous manifestations of PAPA syndrome. Copyright © 2012 by the American College of Rheumatology.

    Full Text Available Introduction: pyoderma gangrenosum (PG is a rare and severe neutrophilic dermatosis asso- ciated with inflammatory bowel disease (IBD and other systemic diseases such as rheu- matoid arthritis and hematological malignancies. Diagnosis is based on clinical criteria and exclusion of other skin disorders. There is no gold standard for the treatment of PG; traditionally intravenous corticosteroids are used, but recently the use of drugs that in- hibit tumor necrosis factor alpha (TNF-alpha has changed the management of PG, showing great effectiveness.Case report: female patient, 23 years old, diagnosed with severe nonspecific ulcerative colitis (UC three years ago, undergoing treatment with oral mesalamine and azathioprine. She developed PG fourteen days after hospital discharge; hospitalization was due to worsening of intestinal disease symptoms. She was successfully treated using biological therapy after unfavorable evolution with corticosteroid therapy.Conclusion: PG, a rare extraintestinal manifestation of IBD of difficult resolution that has significant impact on patient quality of life. The use of biological therapy for PG has higher efficacy in the treatment of patients decreasing wound healing time and return to daily activities.

    We report a 57-year-old woman with a 12-year history of ulcerative pyoderma gangrenosum (PG). Five years after the onset of PG, she developed subcorneal pustular dermatosis (SPD) and biclonal IgA and IgG gammopathy. She developed PG at two bone-marrow biopsy sites, showing pathergy. Finally, she developed multiple myeloma. Although PG and SPD may occur without associated underlying malignancy, these patients should be followed up for any prospective malignancy because of the association between these disorders.

    Pyoderma gangrenosum-like ulcers and cellulitis of the lower extremities associated with recurrent fevers in patients with X-linked (Bruton) agammaglobulinemia have been reported to be caused by Helicobacter bilis (formerly classified as Flexispira rappini and then Helicobacter strain flexispira taxon 8). Consistent themes in these reports are the difficulty in recovering this organism in blood and wound cultures and in maintaining isolates in vitro. We confirmed the presence of this organism in a patient's culture by using a novel application of gene amplification polymerase chain reaction and electrospray ionization time-of-flight mass spectrometry. An adolescent boy with X-linked agammaglobulinemia presented with indurated plaques and a chronic leg ulcer whose origin was strongly suspected to be an H bilis organism. Histologic analysis demonstrated positive Warthin-Starry staining of curvilinear rods, which grew in culture but failed to grow when subcultured. They could not be identified by conventional techniques. A combination of gene amplification by polymerase chain reaction and electrospray ionization time-of-flight mass spectrometry confirmed the identity of this organism. This novel technology was useful in the identification of a difficult-to-grow Helicobacter organism, the cause of pyoderma gangrenosum-like leg ulcers in patients with X-linked agammaglobulinemia. Correct identification of this organism as the cause of pyoderma gangrenosum-like ulcers in patients with X-linked agammaglobulinemia is of great importance for the early initiation of appropriate and curative antibiotic therapy.

    Pyoderma gangrenosum (PG) is a rare disease whose precise etiology remains unknown. It causes rapidly developing skin necrosis and can occur after surgery, or after a nonspecific external stimulus. This condition is difficult to diagnose because it often mimics a fulminant infection. We present a case of very significant local presentation of PG after placement of a venous access device. Fifteen days after placement, the patient developed extensive cutaneous ulcers and necrosis in the subclavicular area, which led to the misdiagnosis of infection. The device was removed and the patient was given antibiotics. Because there was no improvement following antibiotic treatment, combined with the worrying and extensive appearance of the skin and extremely intense pain, the diagnosis of PG was made. The patient was immediately treated with high-dose corticosteroids, resulting in rapid improvement of the lesions and relief of pain. PG should be considered in cases of extensive, antibiotic-resistant ulceration and treatment with corticosteroids should be initiated. Clinical improvement is usually dramatic, with almost immediate suppression of the pain and arrest of the lesion's progression. Early treatment is the best guarantee for an effective recovery.

    Full Text Available Pyoderma gangrenosum (PG is an immune-mediated inflammatory skin condition representing one of the most distinct extraintestinal manifestations of inflammatory bowel disease (IBD. PG occurs independently from intestinal disease activity in about 1–2% of patients suffering from ulcerative colitis or Crohn’s disease and is characterized by chronic deep skin ulcers whose exact pathogenesis is still unknown. So far, patients with ulcerative colitis have only been reported to develop PG during the course of IBD but not at the initial manifestation of bowel symptoms. This is the first report demonstrating the simultaneous onset of ulcerative colitis and severe multifocal PG. In addition, we provide first evidence that infliximab may have a particularly powerful effect in early disseminated PG compared to late-onset PG, advocating an early application of this drug.

  9. Wegener’s granulomatosis and pyoderma gangrenosum – rare causes of facial ulcerations

    Directory of Open Access Journals (Sweden)

    Karolina Kędzierska

    2016-03-01

    Full Text Available Background: Pyoderma gangrenosum (PG is caused by immune system dysfunction, and particularly improper functioning of neutrophils. At least half of all PG patients also suffer from autoimmunological diseases, one of which is Wegener granulomatosis (WG. The purpose of this article was to compare cases of patients with WG and PG in terms of their clinical course, histopathology, and applied treatment. In both, histopathological features are not fully distinct. Data from microbiological and immunological evaluation and clinical presentation are required to establish the diagnosis. We also present the case of a patient with WG and deep facial skin lesions not responding to standard treatment. Methods: Systematic review of the literature in PubMed using the search terms “Wegener granulomatosis AND Pyoderma gangrenosum” and case report. Results: The finding of 22 reports in the literature (PubMed suggests that it is a rare phenomenon. This study revealed a similar rate of comorbidity of WG and PG in both genders and an increased incidence of both diseases after the age of 50. Among skin lesions there was a dominance of ulceration, most often deep and painful, covering a large area with the presence of advanced necrosis and destruction of the surrounding tissue. The most common location proved to be the cervical-cephalic area. The most popular treatment included steroids with cyclophosphamide. Discussion: The rarity of the coexistence of these two diseases results in a lack of effective therapy. In such cases sulfone derivatives are still effective and provide an alternative to standard immunosuppression methods. Hyperbaric therapy and plasmapheresis can also play an important complementary role.

  10. Topical Medical Cannabis: A New Treatment for Wound Pain-Three Cases of Pyoderma Gangrenosum.

    2017-11-01

    Pain associated with integumentary wounds is highly prevalent, yet it remains an area of significant unmet need within health care. Currently, systemically administered opioids are the mainstay of treatment. However, recent publications are casting opioids in a negative light given their high side effect profile, inhibition of wound healing, and association with accidental overdose, incidents that are frequently fatal. Thus, novel analgesic strategies for wound-related pain need to be investigated. The ideal methods of pain relief for wound patients are modalities that are topical, lack systemic side effects, noninvasive, self-administered, and display rapid onset of analgesia. Extracts derived from the cannabis plant have been applied to wounds for thousands of years. The discovery of the human endocannabinoid system and its dominant presence throughout the integumentary system provides a valid and logical scientific platform to consider the use of topical cannabinoids for wounds. We are reporting a prospective case series of three patients with pyoderma gangrenosum that were treated with topical medical cannabis compounded in nongenetically modified organic sunflower oil. Clinically significant analgesia that was associated with reduced opioid utilization was noted in all three cases. Topical medical cannabis has the potential to improve pain management in patients suffering from wounds of all classes. Copyright © 2017 American Academy of Hospice and Palliative Medicine.

    Pyoderma gangrenosum (PG) is a neutrophilic dermatosis of unknown aetiology. We report a 27-year-old male patient with diabetes, who presented with a nonhealing ulcer on the left leg, pruritic hyperpigmented papules distributed over the trunk and limbs, and chronic diarrhoea. He had eosinophilia, low haemoglobin and serum IgE levels, and raised erythrocyte sedimentation rate. Histopathology of the leg ulcer was consistent with the diagnosis of PG, while the histology of the hyperpigmented papule revealed tissue eosinophilia. Subsequent evaluation was conclusive of the diagnosis of PG, idiopathic hypereosinophilic syndrome (IHES) and selective IgE deficiency. Dexamethasone pulse therapy achieved resolution of the ulcer and reduction in the eosinophilia. Further evaluation for the persistent diarrhoea led to a diagnosis of lymphocytic colitis (LC), which responded to budesonide. To our knowledge, the association of PG with IHES, selective IgE deficiency or LC has not been previously reported. © 2015 British Association of Dermatologists.

    Pyoderma gangrenosum (PG) is a rare inflammatory neutrophilic dermatosis for which accurate epidemiological data are limited and therapy remains a challenge. The primary study aim was to examine all cases of PG observed in our regional department over a 15-year period in order to describe the relevant characteristics and outcome under therapy. The medical records of all patients with PG from 1997 to 2012 in the Marne department of France were studied retrospectively. Clinical and histological characteristics, comorbidities, therapeutic modalities and outcome were analysed. Forty-two patients were included (30 women, 12 men). A classical, ulcerative form was found in 39 cases and PG was multifocal in 28 cases. The number of lesions did not differ according to age or the presence of comorbidities. The most frequent first-line treatments were doxycycline (23 cases) and oral corticosteroids (15 cases), regardless of age, number of lesions or existence of comorbidities. Complete remission of PG was obtained in 38 cases (median time to remission: 3 months), with relapse occurring in 17 patients (median time to relapse: 12 months after treatment withdrawal). After a median follow-up of 46 months, 8 patients had died (median time to death: 26 months after treatment initiation). This is the first large French series of patients presenting PG and enabling determination of the annual incidence within the Marne department at around 4.6 cases/1000,000 inhabitants. Our study illustrates the value of first-line treatment with tetracycline, which merits confirmation by further prospective, controlled studies. Copyright © 2015 Elsevier Masson SAS.

    To determine whether ciclosporin is superior to prednisolone for the treatment of pyoderma gangrenosum, a painful, ulcerating skin disease with a poor evidence base for management. Multicentre, parallel group, observer blind, randomised controlled trial. 39 UK hospitals, recruiting from June 2009 to November 2012. 121 patients (73 women, mean age 54 years) with clinician diagnosed pyoderma gangrenosum. Clinical diagnosis was revised in nine participants after randomisation, leaving 112 participants in the analysis set (59 ciclosporin; 53 prednisolone). Oral prednisolone 0.75 mg/kg/day compared with ciclosporin 4 mg/kg/day, to a maximum dose of 75 and 400 mg/day, respectively. The primary outcome was speed of healing over six weeks, captured using digital images and assessed by blinded investigators. Secondary outcomes were time to healing, global treatment response, resolution of inflammation, self reported pain, quality of life, number of treatment failures, adverse reactions, and time to recurrence. Outcomes were assessed at baseline and six weeks and when the ulcer had healed (to a maximum of six months). Of the 112 participants, 108 had complete primary outcome data at baseline and six weeks (57 ciclosporin; 51 prednisolone). Groups were balanced at baseline. The mean (SD) speed of healing at six weeks was -0.21 (1.00) cm(2)/day in the ciclosporin group compared with -0.14 (0.42) cm(2)/day in the prednisolone group. The adjusted mean difference showed no between group difference (0.003 cm(2)/day, 95% confidence interval -0.20 to 0.21; P=0.97). By six months, ulcers had healed in 28/59 (47%) participants in the ciclosporin group compared with 25/53 (47%) in the prednisolone group. In those with healed ulcers, eight (30%) receiving ciclosporin and seven (28%) receiving prednisolone had a recurrence. Adverse reactions were similar for the two groups (68% ciclosporin and 66% prednisolone), but serious adverse reactions, especially infections, were more common in

    Full Text Available This is a report of an atypical presentation of pyoderma gangrenosum (PG in a 26-year-old male who had a negative septic screen. The patient had a life-threatening presentation requiring an intensive care unit (ICU admission for vasopressor support. It was thought that the likely cause of circulatory collapse was an overwhelming cytokine reaction or systemic inflammatory response syndrome (SIRS secondary to extensive PG lesions rather than septic shock. The patient presented with multiple large ulcers, the largest being 4 cm in diameter on the central chest. He developed fevers and circulatory shock preceding his ICU admission. Microbiological specimens, including blood cultures and wound swabs, were negative for any growth (bacterial, fungal, and tuberculosis. No infective foci could be identified as a cause of hemodynamic instability. During admission, the patient’s condition was complicated by multi-organ dysfunction. Wound debridement extending to the deep fascia on the anterior chest, back, bilateral shoulders, and right upper thigh was deemed necessary and performed by the plastic surgery team. Histopathology showed abundant neutrophils but could not confirm an infective process. Overall, the patient made an impressive recovery with almost complete healing of all lesions following oral prednisolone alone. Based on the history and clinical and laboratory findings, a diagnosis of PG complicated by a SIRS was favored. Very few cases of neutrophilic dermatoses have been described in this way. A similar presentation has been described in a 76-year-old female with lower-leg ulcers who developed circulatory shock and required an amputation. Lesions continued to appear despite antibiotics and surgical treatment. Septic screen was negative. She was subsequently diagnosed with PG and recovered rapidly after steroid therapy.

    Pyogenic arthritis, pyoderma gangrenosum, and acne (PAPA) syndrome is a rare autosomal dominant disease that usually presents in childhood with recurrent sterile arthritis. As the child ages into puberty, cutaneous features develop and arthritis subsides. We report the case of a now 25-year-old male patient with PAPA syndrome with the E250K mutation in PSTPIP1. We also present a systematic literature review of other PAPA cases. We conducted a literature search of PubMed using the following search terms: E250K mutation, PSTPIP1, and PAPA. PAPA syndrome is caused by mutations on chromosome 15q affecting the proline-serine-threonine phosphatase-interacting protein 1 (PSTPIP1) gene, also known as CD2-binding protein 1 (CD2BP1). The reported cases of PAPA syndrome currently in the literature involve mutations in A230T and E250Q. One case of a novel E250K mutation has been reported, which presented with a different phenotype to previously described cases of PAPA syndrome. With variation present between disease presentations from case to case, it is possible that the spectrum of PAPA syndrome is wider than currently thought. Further research is needed which may uncover an as-yet undiscovered genetic abnormality linking these interrelated diseases together. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available A 19 year old female with pyoderma gangrenosum was referred to the oculoplastic clinic for evaluation of severe cicatricial ectropion of the right lower eyelid. Examination evidenced important scarring of lower eyelid and malar region with secondary ectropion. A full-thickness skin graft associated with a lateral tarsal strip procedure and scar tissue release was performed. The patient's corticosteroid dose was raised for the procedure, and after surgery there was no healing problem or ulcer formation in the eyelid or in the graft donor site. As pyoderma gangrenosum is associated with a pathergy phenomenon in up to 25% of the cases, the onset of new lesions is a relevant concern when performing surgery in these patients. In this case, the surgery was safely performed under corticosteroid immunosuppression.Paciente do sexo feminino de 19 anos com pioderma gangrenoso foi encaminhada ao setor de Plástica Ocular para avaliação de ectrópio cicatricial grave da pálpebra inferior direita. O exame evidenciou cicatrização importante na pálpebra inferior e região malar com um ectrópio secundário. Foi realizado liberação do tecido cicatricial e um enxerto de pele total associado a "tarsal strip". A dose de corticóide da paciente foi aumentada para a realização do procedimento e não houve problemas de cicatrização ou formação de úlceras na pálpebra ou no sítio doador após a cirurgia. Como o pioderma gangrenoso é associado ao fenômeno de patergia em até 25% dos casos, o surgimento de novas lesões é uma preocupação relevante ao indicar cirurgia nestes pacientes. Neste caso, a cirurgia foi realizada com segurança sob imunossupressão com corticóide.

    Full Text Available Background: Pyoderma ga ngrenosum (PG is a rare, inflammatory, destructive neutrophilic dermatosis, which mimics other ulcerative conditions. Materials and Methods: In a retrospective study based on patients diagnosed with PG over a 3-year period (2010-2013, we evaluated demographics, anatomical sites, number of lesions, subtypes, histopathology, associated conditions, treatment regimens, healing time, and recurrence. Results: Of our five patients, there were three males and two females, age ranging between 19 and 58 years (mean age 38 years. Four had single lesions localized to the lower limbs while one had multiple lesions (more than five over bilateral hands and legs. Ulcerative subtype was observed in all the patients. One exhibited pathergy. Skin biopsies were done in four patients, revealing dense neutrophilic infiltrates in three cases and leukocytoclastic vasculitis in one. Associated systemic diseases were observed in all patients, four having inflammatory bowel disease and one having both systemic lupus erythematosus and anti-phospholipid syndrome. The patients were all treated with systemic corticosteroids either alone or in combination with immunosuppressants (e.g., azathioprine, mycophenolate mofetil, tacrolimus, and wound dressing. Split-thickness skin graft was done in one patient. Complete healing was achieved in all patients, ranging from one to 3 months after diagnosis. No recurrence was reported. Conclusions: Systemic corticosteroids, either alone or in combination with steroid-sparing agents are the mainstay of treatment. Should family physicians encounter a rapidly progressing ulcer that has poor response to usual wound management, timely referral to dermatology should be made.

    Pyoderma gangrenosum (PG) is an uncommon dermatosis with a limited evidence base for treatment. We sought to estimate the effectiveness of topical therapies in the treatment of patients with PG. This was a prospective cohort study of UK secondary care patients with a clinical diagnosis of PG that was suitable for topical treatment (recruited between July 2009 and June 2012). Participants received topical therapy after normal clinical practice (primarily topical corticosteroids [classes I-III] and tacrolimus 0.03% or 0.1%). The primary outcome was speed of healing at 6 weeks. Secondary outcomes included the following: proportion healed by 6 months; time to healing; global assessment; inflammation; pain; quality of life; treatment failure; and recurrence. Sixty-six patients (22-85 years of age) were enrolled. Clobetasol propionate 0.05% was the most commonly prescribed therapy. Overall, 28 of 66 (43.8%) ulcers healed by 6 months. The median time to healing was 145 days (95% confidence interval, 96 days to ∞). Initial ulcer size was a significant predictor of time to healing (hazard ratio, 0.94 [95% confidence interval, 0.88-1.00); P = .043). Four patients (15%) had a recurrence. Our study did not include a randomized comparator. Topical therapy is potentially an effective first-line treatment for PG that avoids the possible side effects associated with systemic therapy. It remains unclear whether more severe disease will respond adequately to topical therapy alone. Crown Copyright © 2016. Published by Elsevier Inc. All rights reserved.

    Pyoderma gangrenosum (PG) is a painful, ulcerating skin disease with poor evidence for management. Prednisolone and ciclosporin are the most commonly used treatments, although not previously compared within a randomized controlled trial (RCT). To compare the cost-effectiveness of ciclosporin and prednisolone-initiated treatment for patients with PG. Quality of life (QoL, EuroQoL five dimensions three level questionnaire, EQ-5D-3L) and resource data were collected as part of the STOP GAP trial: a multicentre, parallel-group, observer-blind RCT. Within-trial analysis used bivariate regression of costs and quality-adjusted life years (QALYs), with multiple imputation of missing data, informing a probabilistic assessment of incremental treatment cost-effectiveness from a health service perspective. In the base case analysis, when compared with prednisolone, ciclosporin was cost-effective due to a reduction in costs [net cost: -£1160; 95% confidence interval (CI) -2991 to 672] and improvement in QoL (net QALYs: 0·055; 95% CI 0·018-0·093). However, this finding appears driven by a minority of patients with large lesions (≥ 20 cm 2 ) (net cost: -£5310; 95% CI -9729 to -891; net QALYs: 0·077; 95% CI 0·004-0·151). The incremental cost-effectiveness of ciclosporin for the majority of patients with smaller lesions was £23 374/QALY, although the estimate is imprecise: the probability of being cost-effective at a willingness-to-pay of £20 000/QALY was 43%. Consistent with the clinical findings of the STOP GAP trial, patients with small lesions should receive treatment guided by the side-effect profiles of the drugs and patient preference - neither strategy is clearly a preferred use of National Health Service resources. However, ciclosporin-initiated treatment may be more cost-effective for patients with large lesions. © 2017 The Authors.

    Pyoderma gangrenosum (PG) is a rare inflammatory skin disorder characterised by painful and rapidly progressing skin ulceration. PG can be extremely difficult to treat and patients often require systemic immunosuppression. Recurrent lesions of PG are common, but the relative rarity of this condition means that there is a lack of published evidence regarding its treatment. A systematic review published in 2005 found no randomised controlled trials (RCTs) relating to the treatment of PG. Since this time, one small RCT has been published comparing infliximab to placebo, but none of the commonly used systemic treatments for PG have been formally assessed. The UK Dermatology Clinical Trials Network's STOP GAP Trial has been designed to address this lack of trial evidence. The objective is to assess whether oral ciclosporin is more effective than oral prednisolone for the treatment of PG. The trial design is a two-arm, observer-blind, parallel-group, randomised controlled trial comparing ciclosporin (4 mg/kg/day) to prednisolone (0.75 mg/kg/day). A total of 140 participants are to be recruited over a period of 4 years, from up to 50 hospitals in the UK and Eire. Primary outcome of velocity of healing at 6 weeks is assessed blinded to treatment allocation (using digital images of the ulcers). Secondary outcomes include: (i) time to healing; (ii) global assessment of improvement; (iii) PG inflammation assessment scale score; (iv) self-reported pain; (v) health-related quality of life; (vi) time to recurrence; (vii) treatment failures; (viii) adverse reactions to study medications; and (ix) cost effectiveness/utility. Patients with a clinical diagnosis of PG (excluding granulomatous PG); measurable ulceration (that is, not pustular PG); and patients aged over 18 years old who are able to give informed consent are included in the trial. Randomisation is by computer generated code using permuted blocks of randomly varying size, stratified by lesion size, and

    Pyogenic sterile arthritis, pyoderma gangrenosum, and acne (PAPA) syndrome (OMIM 604416) is a rare autosomal dominant inherited autoinflammatory syndrome characterized by pyogenic sterile arthritis and less frequently accompanied by pyoderma gangrenosum and acne. It is associated with dominant missense mutations in the proline-serine-threonine phosphatase-interacting protein 1 gene (PSTPIP1) located on chromosome 15. The patient was diagnosed as having features of a PAPA-like syndrome in which cutaneous manifestations, such as pyoderma gangrenosum and acne fulminans, predominated. Sequencing of the PSTPIP1 gene was performed in the patient and his extended family. The patient's DNA analysis revealed a homozygous nucleotide exchange c.773G>C in the PSTPIP1 gene, leading to the substitution of glycine 258 by alanine (p.Gly258Ala), a previously reported heterozygous polymorphism. Heterozygous changes were identified in both of the patient's parents and in 7 other family members, all of whom were asymptomatic. The patient was treated with canakinumab, a human anti-interleukin 1β monoclonal antibody, which led to rapid remission of the symptoms. To our knowledge, this is the first reported case of the resolution of dermatological symptoms associated with a PAPA-like syndrome using canakinumab treatment. Further study of the p.Gly258Ala variant is warranted to determine whether this mutation has a role in causing an apparently recessive cutaneous syndrome resembling PAPA syndrome.

    Perianal sepsis with ecthyma gangrenosum is a severe and potentially mutilating complication in immunocompromised children. Therapies include antimicrobial treatment, incision and drainage, generous tissue debridement, and skin transplantation. We describe 3 children with acute lymphoblastic leukemia having sepsis with Pseudomonas aeruginosa in febrile neutropenia and severe perianal infections treated relatively early with a protective colostomy. Indications for colostomy were nonhealing wounds, and ceaseless pain. All patients showed a rapid reduction of pain. Complete wound healing was seen in 2 patients, and considerable pain reduction and increased quality of life were seen in a third patient during palliative care. These results suggest that a protective colostomy should be considered early in the management of immunocompromised children with ecthyma gangrenosum.

    Full Text Available Introduction. Ecthyma gangrenosum is a rare disease of the skin that causes the localized necrosis of the skin and subcutaneous fat tissue, leading to the multiple ulcerations surrounded by local hyperaemia. The ulcerations are usually localized in groins, and perianal area. In the majority of cases ecthyma is caused by a Pseudomonas aeruginosa sepsis. The disease usually appears in immunocompromized, most frequently hematological patients. Case report. We presented a 78-year-old woman who had been treated for non-Hodgkin lymphoma for the last 18 years. She had recently been given cytotoxics which led to neutropenia. The patient suddenly developed high fever, chill and diarrhea, followed by ecthyma gangrenosum cutaneous lesions in groins, axillas, right side of the neck and umbilicus. Pseudomonas aeruginosa and Proteus mirabilis, that were sensitive to several antibiotics were isolated. The treatment included rehydratation, antibiotics, surgical debridement and regular dressing with antiseptics. The healing of all lesions was achieved after sixteen weeks of the treatment. Conclusion. If haemorrhagic- necrotic lesions of the skin are developed in immunocompromised, usually haematologic patients, an Ecthyma gangrenosum has to be considered immediately, material for identification of a cause has to be taken, followed by immediate administration of antibiotics effective against Pseudomonas aeruginosa. Surgical debridement and other therapeutic modalities are to be considered in some patients. .

    We report a diagnosis of ecthyma gangrenosum (EG) in 4 females of mean age 54.8 (range 43-64) years, within 10 months. Severe drug reaction treated with high dose systemic corticosteroids in patient 1, acute myelocytic leukemia treated with high dose dexamethasone and multiple broad-spectrum antibiotics in patient 2precede the onset of EG. Patients 3 and 4 had vasculitic purpura and hemodialysis. In addition, patient 3 was receiving multiple broad-spectrum antibiotics plus anti-tuberculosis (TB) drugs for gastric TB, while patient 4 was on melphalan and high dose systemic corticosteroids. Pseudomonas aeruginosa was isolated from blood culture of the first 3 patients and skin culture of patient one. Blister aspirate from patient 4 yielded Candida albicans. Factors enhancing skin invasion by pathogenic organisms in our patients were breached skin integrity, therapy with high dose corticosteroids and multiple broad-spectrum antibiotics, hematologic malignancies and chemotherapy with severe neutropenia.

    Full Text Available Dogs with a history of more than three episodes of skin infections in a period of one year were selected for a study on recurrent pyoderma. Oral enrofloxacin along with appropriate simultaneous medication for the underlying associated conditions were chosen as therapy for recurrent pyoderma in dogs. Response to therapy was excellent in all the cases. Improvement was noticed by 12 to 20 days and 20 to 26 days in recurrent superficial and deep pyoderma respectively. Relapse occurred in one dog by 45 days due to re-introduction of allergic food. Enrofloxacin proved to be an effective, safe and convenient antibiotic for the treatment of recurrent pyoderma in dogs.

    Full Text Available Background: Although prevalence of MRSA strains is reported to be increasing, there are no studies of their prevalence in community-acquired primary pyodermas in western India. Aims: This study aimed at determining the prevalence of MRSA infection in community-acquired primary pyodermas. Methods: Open, prospective survey carried out in a tertiary care hospital in Mumbai. Materials and Methods: Eighty-six patients with primary pyoderma, visiting the dermatology outpatient, were studied clinically and microbiologically. Sensitivity testing was done for vancomycin, sisomycin, gentamicin, framycetin, erythromycin, methicillin, cefazolin, cefuroxime, penicillin G and ciprofloxacin. Phage typing was done for MRSA positive strains. Results : The culture positivity rate was 83.7%. Staphylococcus aureus was isolated in all cases except two. Barring one, all strains of Staphylococcus were sensitive to methicillin. Conclusions: Methicillin resistance is uncommon in community-acquired primary pyodermas in Mumbai. Treatment with antibacterials active against MRSA is probably unwarranted for community-acquired primary pyodermas.

    There is a lack of studies comparing topical antiseptics to systemic antibiotics in the treatment of canine superficial pyoderma. To compare the efficacy of topical chlorhexidine with systemic amoxicillin-clavulanic acid for the treatment of canine superficial pyoderma. A randomized controlled trial was conducted in dogs with superficial pyoderma. Group T (n = 31) was treated topically with 4% chlorhexidine digluconate shampoo (twice weekly) and solution (once daily) for 4 weeks. Group S (n = 20) was treated orally with amoxicillin-clavulanic acid (25 mg/kg) twice daily for 4 weeks. Bacterial culture and susceptibility testing were performed on clinical specimens collected before treatment. Severity of lesions and number of intracellular bacteria were evaluated using four-point scales to calculate a total pyoderma score for each dog. Pruritus was assessed by owners using a visual analog scale (range 0-10). Scores were analysed for statistical differences between groups T and S. Staphylococcus pseudintermedius was isolated from 48 dogs, including eight meticillin-resistant strains (MRSP). Although the number of dogs was small, no significant differences in pyoderma and pruritus scores were observed between groups throughout the study except for day 1, when group S had a significantly higher total score than group T (P = 0.03). Treatment with chlorhexidine products resulted in resolution of clinical signs in all dogs including those infected with MRSP. Topical therapy with chlorhexidine digluconate products may be as effective as systemic therapy with amoxicillin-clavulanic acid. This finding supports the current recommendations to use topical antiseptics alone for the management of superficial pyoderma. © 2015 The Authors.

    Superficial pyoderma is traditionally considered rare in cats but may be more prevalent than previously reported. To better characterize superficial pyoderma in cats. Fifty-two cats from a dermatology referral population over a 10 year period. This study was retrospective. Cases were included if neutrophils and intracellular bacteria were reported from surface cytology of skin lesions. Medical records were reviewed for signalment, historical and clinical data, cytology results, primary skin diagnoses and treatment details. Disease prevalence was 20%, with no breed or sex predispositions. The estimated median age of onset was 2 years, affecting 54% of cats by 3 years and 23% after 9 years. Fewer cases presented during winter (15%) compared with other seasons. Skin lesions were typically multifocal, affecting the face (62%), neck (37%), limbs (33%) and ventral abdomen (29%) most commonly. Crusting (83%), alopecia (67%), ulceration/erosion (54%) and erythema (46%) were common lesion types. Pruritus was reported in 92% of cats. Underlying hypersensitivities (confirmed in 60%; suspected in 19%), and atopic dermatitis specifically (confirmed in 48%), were the most frequent primary dermatoses. Cats were treated with a variety of systemic and/or topical antimicrobials. The overall apparent response was considered good in 61% and poor in 27% of cats. Recurrence was confirmed or suspected in 42% of cats. Feline superficial pyoderma was more prevalent in this study population than previously reported. Young cats with hypersensitivities and older cats were more commonly affected, and a variety of lesion types and distributions occurred. © 2012 The Authors.

    In veterinary medicine, Staphylococcus schleiferi was previously assumed to be an inhabitant of carnivore skin, however, more recently, it has been repeatedly documented in the literature as both an inhabitant and as a pathogen. In order to determine the frequency of nasal carriage, and the methicillin susceptibility pattern of S. schleiferi from healthy dogs as well as dogs with otitis and/or pyoderma, a prospective study including 24 dogs with healthy ears and skin, 27 dogs with healthy ears and pyoderma, 15 dogs with otitis without pyoderma and 20 dogs with both otitis and pyoderma was performed. Specimens were obtained and cultured and isolates were identified as S. schleiferi based on growth and biochemical characteristics. S. schleiferi was isolated from the nares of 1 healthy dog, 3 dogs with recurrent pyoderma, 2 dogs with recurrent otitis, and 1 dog with both recurrent otitis and pyoderma. One of the S. schleiferi isolates was methicillin resistant. Nasal carriage of S. schleiferi does occur in healthy dogs as well as dogs with otitis and pyoderma. Methicillin resistant and sensitive S. schleiferi can be found in the nares of dogs with diseased ears and skin. Copyright © 2012 Elsevier B.V. All rights reserved.

    The clinical and antibacterial efficacy of two shampoos used as a sole antibacterial treatment in dogs with superficial pyoderma were investigated and compared. In a randomised, partially blinded study, a 3 per cent chlorhexidine gluconate shampoo (Chlorhex 3; Leo Animal Health) was compared against a 2.5 per cent benzoyl peroxide shampoo (Paxcutol; Virbac) in 22 dogs with superficial pyoderma. Dogs were washed two to three times weekly with a 10-minute contact time over 21 days. Clinical scores and bacterial counts were assessed on days 1, 8 and 22 and compared within and between treatment groups; overall response was assessed at the end of the study. Twenty dogs completed the study; 15 (68.2 per cent) showed an overall clinical improvement and the clinical signs resolved in three chlorhexidine-treated dogs. In the chlorhexidine-treated group, scores for papules/pustules (P<0.001), investigator-assessed pruritus (P=0.003), total bacterial counts (P=0.003) and counts for coagulase-positive staphylococci (P=0.003) were reduced after three weeks. Scores and bacterial counts did not vary significantly in the benzoyl peroxide-treated group.

    Full Text Available Context: The uncontrolled use of antibiotics has resulted in a relentless spread of multiresistant strains of Staphylococcus aureus. There are studies conducted in medical colleges in Chandigarh, Chennai, Mumbai and Vellore comparing pyodermas in the community and hospital setting based on clinical and bacteriological parameters. Aims: This study, conducted over 1½ years from March 2009 to August 2010, aimed at analyzing the clinical spectrum and antibiotic sensitivity pattern of community and hospital-associated (HA staphylococcal pyoderma. It also assessed the prevalence of methicillin-resistant S. aureus (MRSA in the community and hospital cohort settings. Subjects and Methods: The study comprised of 200 cases of staphylococcal pyodermas, derived from the community (150 cases and hospital (50 cases. Patients were evaluated based on their clinical presentation; antibiotic susceptibility was tested using the Kirby-Bauer disk diffusion method. Statistical Analysis Used: Statistical significance between individual attributes between the community and HA staphylococcal pyoderma groups was analyzed using Chi-square test and mean differences using student′s t-test. Results: Factors associated with community-associated (CA pyodermas were young age (P = 0.0021, primary pyodermas, and involvement of extremities, while those with HA pyodermas were middle age, secondary pyodermas, and significantly increased body surface involvement (P = 0.041. Incidence of CA-MRSA was 11.3%, while that of HA-MRSA was 18%. Conclusions: A high level of resistance to first-line drugs such as penicillin, ciprofloxacin and cotrimoxazole was observed, more so in the hospital strain than in the community strain. S. aureus demonstrated good susceptibility to cephalosporins. Though the two strains of MRSA differed clinically, they showed 100% sensitivity to vancomycin and linezolid.

    Full Text Available A 35 year male suffering from acid-peptic disease since last 15 years developed multiple, progressive necrotic gangrenous ulcers with pus discharge since one month. He also had cellulites and a big serpiginous necrotic ulcer of left ring finger resembling decubitus ulcer. Smears of pus from both types of ulcers revealed gram-negative bacilli. Culture of pus from both sites showed growth of pseudomonas aeruginosa. Blood culture was negative. Diagnosis of Echthyma gangrenosum (EG was established histopathologically as gram-negative bacilli invaded the dermal vessels. Complete cure occurred after 3 months of treatment with different antibiotics; 80% of ulcers healed with cefadroxyl therapy.

    Pyoderma gangraenosum is an immune-mediated, inflammatory, neutrophilic dermatosis of unknown etiology, which represents one of the extraintestinal manifestations of inflammatory bowel disease. It is a rare disease that occurs in less than 1% of patients with inflammatory bowel disease and with the same ratio in patients with Crohn's disease and ulcerative colitis. A 36-year-old woman was diagnosed with ulcerative colitis 6 years before admission to our dermatology department with an acute disseminated pyoderma gangraenosum with mucosal involvement, during a flare of ulcerative colitis. Disease progression was interrupted by intravenous administration of the tumor necrosis factor-α inhibitor infliximab at 5 mg/kg at weeks 0, 2, and 6 (1st cycle) and every 8 weeks thereafter. Improvement of intestinal, skin and oral manifestations was evident already after the 1st cycle of treatment and has been maintained since (at least 16 months). This case report is one of very few on disseminated pyoderma gangraenosum with oral involvement complicating ulcerative colitis, where infliximab was shown to have a rapid efficacy on skin, mucosal and bowel symptoms.

    Full Text Available Primary cutaneous anaplastic large cell lymphoma (pcALCL forms 9% of the cutaneous T-cell lymphomas. It usually presents as solitary reddish brown ulcerating nodule or indurated plaque. Sometimes, it mimics other dermatological diseases such as eczema, pyoderma gangrenosum, pyogenic granuloma, morphea, and squamous cell carcinoma. Our case presented with large pyogenic granuloma like lesion with regional lymphadenopathy. Since pcALCL is rare, one can misdiagnose such cases and therefore high index of suspicion is necessary.

    2011-01-01

    Background Pyoderma gangrenosum–like ulcers and cellulitis of the lower extremities associated with recurrent fevers in patients with X-linked (Bruton) agammaglobulinemia have been reported to be caused by Helicobacter bilis (formerly classified as Flexispira rappini and then Helicobacter strain flexispira taxon 8). Consistent themes in these reports are the difficulty in recovering this organism in blood and wound cultures and in maintaining isolates in vitro. We confirmed the presence of this organism in a patient’s culture by using a novel application of gene amplification polymerase chain reaction and electrospray ionization time-of-flight mass spectrometry. Observation An adolescent boy with X-linked agammaglobulinemia presented with indurated plaques and a chronic leg ulcer whose origin was strongly suspected to be an H bilis organism. Histologic analysis demonstrated positive Warthin-Starry staining of curvilinear rods, which grew in culture but failed to grow when sub-cultured. They could not be identified by conventional techniques. A combination of gene amplification by polymerase chain reaction and electrospray ionization time-of-flight mass spectrometry confirmed the identity of this organism. Conclusions This novel technology was useful in the identification of a difficult-to-grow Helicobacter organism, the cause of pyoderma gangrenosum–like leg ulcers in patients with X-linked agammaglobulinemia. Correct identification of this organism as the cause of pyoderma gangrenosum–like ulcers in patients with X-linked agammaglobulinemia is of great importance for the early initiation of appropriate and curative antibiotic therapy.

    Full Text Available Pyoderma vegetans (PV is a rare inflammatory disorder characterized by vegetating pustules and plaques affecting the skin and mucosal membranes. It is believed that this entity is mostly associated with inflammatory bowel disease (IBD, chronic malnutrition, human immunodeficiency virus (HIV, malignancies, and other immunocompromised states. Pyoderma vegetans occurs more commonly in young and middle-aged adults. There is no sex predilection for this entity. The lesions could heal spontaneously, but usually recur and become chronic. Our patient was an 11-year-old girl suspected to have primary combined immunodeficiency complicated by chronic recurrent vegetating pustular lesions on the face and postauricular area since one year of age. The histological features of the lesions were consistent with pyoderma vegetans. This is the first case of PV beginning from early infancy in the setting of primary immunodeficiency and in an unusual location.

    Full Text Available Background: Pyoderma is common in India and other tropical countries. Staphylococcus aureus is the commonest causative agent ofpyoderma. Aims and Objectives: To know the antibiotic susceptibility and bacteriophage pattern of Staphylococcus aureus isolated from pyoderma infection. Materials and Methods: One hundred clinically diagnosed pyoderma cases were investigated bacteriologically. A total of 59 isolates of S. aureus were subjected to antibioticsusceptibility testing by Kirby Bauer’s disk diffusion method and phage typing by routine test dilution X 100 bacteriophages. Results: Most of the strains were resistant to penicillin, ampicillin and were susceptible to gentamicin, streptomycin and erythromycin. Multidrug resistance was also high among these strains. Regarding the phage types, Phage type 52 (15 strains, 96 (8 strains and 71(16strains were predominant among the typed strains (55.95% of S. aureus. The most common group was mixed phage group (17% followed by phage group I (13.55%. Conclusion: Knowledge of antibioticsusceptibility pattern is essential to give proper antibiotic therapy and avoid unnecessary medication with non-effective drugs, which may increase resistance. Gentamicin, streptomycin and erythromycin are the drugs of choice in that order. Association of phage typing and antibiotic sensitivity of S. aureus showed the predominance of phage group III with greater frequency of penicillin resistance.

    2013-05-01

    Full Text Available Successful treatment of canine pyoderma has become compromised owing to the development of antimicrobial resistance with accompanying recurrence of infection. Canine skin samples submitted to a veterinary diagnostic laboratory for microbiological culture and sensitivity between January 2007 and June 2010, from which Staphylococcus intermedius was isolated, were selected for this investigation. Antimicrobial resistance of S. intermedius was most prevalent with reference to ampicillin followed by resistance to tetracycline and then potentiated sulphonamides. In general, antimicrobial resistance was low and very few methicillin-resistant isolates were detected. Temporal trends were not noted, except for ampicillin, with isolates becoming more susceptible, and potentiated sulphonamides (co-trimoxazole, with isolates becoming more resistant. In general, both the Kirby–Bauer disc diffusion and broth dilution minimum inhibitory concentration tests yielded similar results for the antimicrobial agents tested. The main difference was evident in the over-estimation of resistance by the Kirby–Bauer test for ampicillin, co-trimoxazole, penicillin and doxycycline. Knowledge of trends in bacterial resistance is important for veterinarians when presented with canine pyoderma. Analysis of antimicrobial susceptibility profiles of S. intermedius isolated from canine pyodermas will guide veterinarians’ use of the most appropriate agent and encourage prudent use of antimicrobials in companion animals.

  20. Diseases associated with hidranitis suppurativa: part 2 of a series on hidradenitis.

    Science.gov (United States)

    Scheinfeld, Noah

    2013-06-15

    Hidradenitis suppurativa (HS), a pathologic follicular disease, impacts patients' lives profoundly and usually occurs in isolation. The diseases with the strongest association are obesity, depression, and pain. HS is associated with many diseases including acne conglobata (AC), dissecting cellulitis, pilonidal cysts, and obesity. Pyoderma fistulans sinifica (fox den disease) appears to be the same entity as Hurley Stage 2 of 3 HS. The rate of acne vulgaris in HS patients mirrors unaffected controls. The most common, albeit still uncommon, association is with seronegative, haplotype unlinked arthritis (most importantly B27), in particular spondolyarthritis. Crohn disease and HS occur together at a rate that varies from 0.6% to 38% in retrospective cases series. Ulcerative colitis occurred with HS in 14% of patients in one series. The next most common association is with pyoderma gangrenosum, but this association is likely under-reported. Synovitis-Acne-Pustulosis Hyperostosis-Osteitis (SAPHO) syndrome, which is rare, has more than 10 reports linking it to HS. Nine case reports have linked Dowling-Degos disease (DDD) to HS and two reports related HS to Fox-Fordyce disease (FF), but because both occur in the axilla this might be a mere coincidence. HS is rarely associated with ophthalmic pathology. Specifically, more than 5 reports link it to Keratitis-Ichthyosis-Deafness syndrome (KID); greater than10 cases link it to interstitial keratitis and 2 cases are linked to Behçet's disease. The presence of proteinuria and acute nephritis link HS to the kidney, especially since and reports have documented resolution of HS after renal transplant. Florid steatocystoma multiplex, Sjogren Syndrome, and HS have been linked and their reports likely underestimate their coincidence because all these entities involve occlusion (albeit by different mechanisms). Three reports link HS and amyloid, but both share some common genetic underpinnings and thus the coincidence of these

    We conducted a comprehensive, systematic review of the global childhood population prevalence of impetigo and the broader condition pyoderma. PubMed was systematically searched for impetigo or pyoderma studies published between January 1 1970 and September 30 2014. Two independent reviewers extracted data from each relevant article on the prevalence of impetigo. Sixty-six articles relating to 89 studies met our inclusion criteria. Based on population surveillance, 82 studies included data on 145,028 children assessed for pyoderma or impetigo. Median childhood prevalence was 12·3% (IQR 4·2-19·4%). Fifty-eight (65%) studies were from low or low-middle income countries, where median childhood prevalences were 8·4% (IQR 4·2-16·1%) and 14·5% (IQR 8·3-20·9%), respectively. However, the highest burden was seen in underprivileged children from marginalised communities of high-income countries; median prevalence 19·4%, (IQR 3·9-43·3%). Based on data from studies published since 2000 from low and low-middle income countries, we estimate the global population of children suffering from impetigo at any one time to be in excess of 162 million, predominantly in tropical, resource-poor contexts. Impetigo is an under-recognised disease and in conjunction with scabies, comprises a major childhood dermatological condition with potential lifelong consequences if untreated.

    Ulcerative colitis is occasionally complicated by dermatological disorders presenting as extra-intestinal manifestations, including erythema nodosum and pyoderma gangrenosum. Sweet's syndrome is considered to be a rare cutaneous disease in patients with ulcerative colitis. To date, only 17 cases of Sweet's syndrome complicating ulcerative colitis have been reported in the English literature. Here, we report a case of a 41-year-old male who had been suffering from ulcerative colitis for 20 years. He was admitted to hospital with hematochezia, diarrhea and fever, and painful erythematous nodules on the face and arms. Histological examination of skin biopsies showed inflammatory cell infiltration composed mainly of neutrophils without evidence of necrotizing vasculitis, and the condition was diagnosed as Sweet's syndrome. The patient was treated with prednisolone and leukocytapheresis and the erythematous nodules on the skin, as well as the abdominal symptoms and endoscopic findings of ulcerative colitis, immediately improved. In this paper we report on this case and review the literature concerning ulcerative colitis and Sweet's syndrome.

    2010-01-01

    PAPA syndrome (Pyogenic Arthritis, Pyoderma gangrenosum, and Acne) is an autosomal dominant, hereditary auto-inflammatory disease arising from mutations in the PSTPIP1/CD2BP1 gene on chromosome 15q. These mutations produce a hyper-phosphorylated PSTPIP1 protein and alter its participation in activation of the “inflammasome” involved in interleukin-1 (IL-1β) production. Overproduction of IL-1β is a clear molecular feature of PAPA syndrome. Ongoing research is implicating other biochemical pathways that may be relevant to the distinct pyogenic inflammation of the skin and joints characteristic of this disease. This review summarizes the recent and rapidly accumulating knowledge on these molecular aspects of PAPA syndrome and related disorders. PMID:21532836

    Tobacco smoking is a serious and preventable health hazard that can cause or exacerbate a number of diseases and shorten life expectancy, but the role of smoking as an etiologic factor in the development of skin disease is largely unknown. Although epidemiological evidence is sparse, findings...... suggest that tobacco smoking is a contributing factor in systemic lupus erythematosus, psoriasis, palmoplantar pustulosis, cutaneous squamous cell carcinoma, hidradenitis suppurativa, and genital warts. In contrast, smoking may confer some protective effects and mitigate other skin diseases, notably...... pemphigus vulgaris, pyoderma gangrenosum, aphthous ulcers, and Behçet's disease. Various degenerative dermatologic conditions are also impacted by smoking, such as skin wrinkling and dysregulated wound healing, which can result in post-surgical complications and delayed or even arrested healing of chronic...

    Antimicrobial resistance may be overestimated in bacterial isolates from clinical samples because veterinarians often submit samples in cases of treatment failure or recurrent cases, which are more frequently associated with resistant strains. To assess to what extent the prevalence of antimicrobial resistance in Staphylococcus pseudintermedius isolated from first-time superficial pyoderma differs from canine skin isolates from clinical samples with unknown clinical background. Two study groups were enrolled in Denmark between March 2012 and October 2013: 57 dogs with first-time superficial pyoderma and no prior antimicrobial treatment (Group A); and 289 different dogs for which skin specimens were submitted for culture during the study (Group B). One S. pseudintermedius isolate from each dog was confirmed by MALDI-TOF mass spectrometry and tested for antimicrobial susceptibility by broth microdilution. Resistance levels in the two groups were compared by Fisher's exact test. Clindamycin resistance was less frequent in Group A (14%) than in Group B (27%) (P = 0.02). Similar trends were observed for amoxicillin-clavulanic acid (1.8 versus 4.8%), chloramphenicol (8.8 versus 14.5%), enrofloxacin (1.8 versus 3.5%), oxacillin (1.8 versus 4.8%) and trimethoprim/sulfamethoxazole (3.5 versus 5.9%). Oxacillin resistance was significantly associated with resistance to six of seven non-β-lactams. The prevalence of lincosamide resistance is markedly influenced by patients' clinical and antimicrobial treatment history. To limit selection of multidrug-resistant bacteria, lincosamides are appropriate empirical choices for treatment of first-time superficial pyoderma even though resistance is not infrequent. Culture and susceptibility testing are, however, recommended for all pyoderma patients. © 2015 ESVD and ACVD.

    Thalidomide is a synthetic glutamic acid derivative first introduced in 1956 in Germany as an over the counter medications. It was thought to be one of the safest sedatives ever produced as it was effective in small doses, was not addictive, and did not have acute side-effects such as motor impairment, but was quickly removed from market after it was linked to cases of severe birth defects. The Food and Drug Administration approved use in the treatment of erythema nodosum leprosum. Further, it was shown its effectiveness in unresponsive dermatological conditions such as actinic prurigo, adult Langerhans cell hystiocytosis, aphthous stomatitis, Behçet syndrome, graft-versus-host disease, cutaneous sarcoidosis, erythema multiforme, Jessner-Kanof lymphocytic infiltration of the skin, Kaposi sarcoma, lichen planus, lupus erythematosus, melanoma, prurigo nodularis, pyoderma gangrenosum and others. In May 2006, it was approved for the treating multiple myeloma. New thalidomide analogues have been developed but lack clinical experience. This paper is a review of the history, pharmacology, mechanism of action, clinical applications and side effects of thalidomide and its analogues. Copyright © 2013 Elsevier España, S.L.

    In 2007, a previously unrecorded disease, fur animal epidemic necrotic pyoderma (FENP), was detected in farmed mink (Neovision vision), foxes (Vulpes lagopus) and Finnraccoons (Nyctereutes procyonoides) in Finland. Symptoms included severe pyoderma with increased mortality, causing both animal welfare problems and economic losses. In 2011, an epidemiologic questionnaire was mailed to all members of the Finnish Fur Breeders' Association to assess the occurrence of FENP from 2009 through the first 6 months of 2011. The aim was to describe the geographical distribution and detailed clinical signs of FENP, as well as sources of infection and potential risk factors for the disease. A total of 239 farmers (25%) returned the questionnaire. Clinical signs of FENP were observed in 40% (95% CI 34-46%) of the study farms. In addition, the survey clarified the specific clinical signs for different animal species. The presence of disease was associated with the importation of mink, especially from Denmark (OR 9.3, 95% CI 2.6-33.0). The transmission route between Finnish farms was associated with fur animal purchases. Some risk factors such as the farm type were also indicated. As such, FENP was detected more commonly on farms with more than one species of fur animal in comparison to farms with, for example, only foxes (OR 4.6, 95% CI 2.4-8.6), and the incidence was higher on farms with over 750 breeder mink compared to smaller farms (OR 3.8, 95% CI 1.6-9.0). Contact between fur animals and birds and other wildlife increased the risk of FENP on farms. Responses also indicated that blocking the entry of wildlife to the animal premises protected against FENP. FENP was most likely introduced to Finland by imported mink and spread further within the country via domestically purchased fur animals. Some potential risk factors, such as the type and size of the farm and contact with wildlife, contributed to the spread of FENP. Escape-proof shelter buildings block the entry of wildlife

    Full Text Available Ecthyma gangrenosum (EG is a cutaneous lesion classically associated with potentially fatal Pseudomonas septicemia in immunocompromised patients. Other bacterial and fungal pathogens have also been implicated. Although EG typically occurs in immunocompromised or neutropenic patients, it may occasionally affect a previously healthy person. The cutaneous findings are characteristic with small indurated papulovesicles progressing rapidly to necrotic ulcers with surrounding erythema and a central black Eschar. While lesions can occur at any site, most are commonly found over the buttocks, perineum, limbs, and axillae. We describe a case of EG in periorbital region in a previously healthy woman who responded to appropriate antibiotic treatment for Pseudomonas. It is very important to establish the diagnosis early so that appropriate systemic antibiotic therapy can be initiated to reduce morbidity and potential mortality.

    A 66-year-old man presented with a chief complaint of glans penis pain, induration, and discharge of pus. He was prescribed a course of antibiotics, but the condition persisted despite treatment. Thus, we differrentially diagnosed the patient with penile tuberculosis and pyoderma gangrenosum, and performed a biopsy of the penis. The biopsy result was thickening of the horny layer epidermis with only a foreign body granuloma composed of inflammatory cells, and did not lead to a definitive diagnosis. Thoraca-abdominal computed tomography revealed axillary lymphadenopathy with necrosis. Suspecting tuberculosis lymphadenitis, we performed T-spot and QuantiFERONtests. The result was T-spot negative and QuantiFERONpositive, so we diagnosed the patient with penile tuberculosis, and started antituberculosis medication. In about half a year after the start of treatment the symptoms subsided, and lymphadenopathy showed reduction.

    2018-01-01

    Full Text Available Hidradenitis suppurativa is a chronic, disabling, suppurative disease characterized by deep tender subcutaneous nodules; complicated by fibrosis and extensive sinuses affecting primarily the apocrine gland bearing areas. It affects all races in early 20s with greater prevalence seen in women (3 to 5:1. The estimated disease prevalence is 1 - 4 %. The disease is speculated to be caused by follicular structural abnormalities with associated risk factors as smoking, obesity, positive family history and shaving. Certain co-morbidities can also be seen such as inflammatory bowel disease, spondyloarthropathies, epithelial tumors, pyoderma gangrenosum etc. Treatment modalities include counseling of the patient to lose weight if obese, to wear loose clothes, stop smoking and maintain good hygiene. Topical antibiotics, like 1% clindamycin, have shown to give good results along with benzoyl peroxide wash. Orally cocktail of antibiotics can be given, though biologicals remain the best treatment option. Surgical excision can be done in later stages and in recalcitrant cases.

    Infliximab is an accepted induction and maintenance treatment for patients with Crohn's disease. The effectiveness of infliximab has been demonstrated for both active luminal disease and for enterocutaneous fistulisation. In addition, infliximab can be administered for extraintestinal symptoms of Crohn's disease, such as pyoderma gangrenosum, uveitis and arthropathy. Maintenance treatment with infliximab is effective and is regarded as safe as long as the necessary safety measures are heeded. Infusion reactions occur in 3 to 17% of the patients and are associated with the formation of antibodies to infliximab. A reduction in infusion reactions is possible by the concurrent administration of steroids and the use of immunosuppressants (azathioprine, 6-mercaptopurine, methotrexate). Furthermore, immunosuppressants increase the duration of the response to infliximab. For these reasons, the concomitant use of immunosuppressants with infliximab is recommended. Infections and most specifically tuberculosis need to be ruled out before infliximab is administered. Up to now, there are no indications for a connection between an increased risk for malignancies and treatment with infliximab.

    Full Text Available Lincomycin is chemically distinct from all other available antibiotics except its semi-synthetic derivative clindamycin. Though it has been in the market for over three decades, there were not many clinical studies in India. This study has been undertaken to know its efficacy against Staphylococcus aureus, commonest organism of pyodermas in children. Material was taken from the lesions of 100 fresh cases of various types of pyodermas in children and studied by Gram stain and in 50% human blood agar and nutrient agar according to standard methods. The staphylococci thus isolated were tested for linocomycin susceptibility by using the disc diffusion technique. Lincomycin was given to all these children in a daily dose of 30 mg/kg 5 - 10 days. Treatment failure was defined as persistence of lesions after 10 days of treatment. 75% strains of staphylococci were susceptible to lincomycin in vitro and 95% of the patients responded to 5-10 days treatment. Five out of 100 children did not respond to treatment even after 10 days. No case of relapse was noticed among these 95 children for a period of 2 weeks. No side effects were observed and the drug was very well tolerated. Being highly effective and least toxic linomycin deserves a place in the antimicrobial arsenal of the modern dermatologists.

    Bacterial pyoderma is a frequent presentation in dogs. Despite the widespread availability of effective systemic and topical antimicrobial products, good clinical practice currently recommends avoidance of long-term use to mitigate the development of bacterial resistance. To evaluate the speed of resolution of clinical signs of bacterial pyoderma in dogs treated with a systemic antimicrobial agent with or without the use of an adjunctive spray with antimicrobial properties. Twelve dogs with superficial bacterial pyoderma. In this controlled and blinded study, all dogs were treated with oral cefalexin and a topical spray (PYOClean Spray) for 4 weeks. The spray was applied to one half of each dog's body, whereas a placebo spray was applied to the other half. Twelve dogs completed the study. Mean clinical scores were significantly reduced on spray-treated sites, for test product and placebo (respectively), by 47% and 34% at Week 1, 83% and 60% at Week 2, 95% and 82% at Week 3, and 100% and 96% at Week 4. Fifty percent of treated sites were considered clinically and cytologically cured at Week 2, 83% at Week 3, and 100% at Week 4 compared to 8%, 50% and 83% for the placebo sites, respectively. These results demonstrate that use of a topical spray which contains plant-derived essential oils and fatty acids, and compounds with antimicrobial properties (Manuka oil and N-acetyl cysteine) may help to speed resolution of pyoderma and may allow for shorter antimicrobial treatment time. © 2016 ESVD and ACVD.

    Full Text Available Introduction. Skin findings in leukemias may be divided into specific lesions (leukemia cutis and non-specific lesions (leukemids which may be found in up to 80% of all patients with leukemias. The leukemids vary clinically and they are usually a manifestation of bone marrow or immunologic impairment, but also Sweet syndrome, pyoderma gangrenosum, erythroderma, maculopapular exanthema, prurigo-like papules, generalized pigmentation, follicular mucinosis, generalized pruritus may be found during the course of leukemia. Case report. We report a 70-year-old male with a 3-month history of erythema, papules and pustules on the face, ears and neck and over a month history of refractory anemia, anorexia, weight loss, malaise, and fever. Physical examination revealed symmetric erythematous, violaceous papules, papulo-nodules and plaques with slate scale and sparse, small pustules on the face, earlobes and neck. Histopathologic findings of involved skin showed diffuse mixed inflammatory cell infiltrate with perifollicular accentuation and focal granulomatous inflammation in the papillary and upper reticular dermis. Extensive checkup revealed the presence of acute myeloid leukemia French- American-British (FAB classification subtype M2, with signs of three-lineage dysplasia. The patient was treated by L6 protocol which led to complete remission, both in bone marrow and skin, but after seven months he had relapse of leukemia with the fatal outcome. Conclusion. This case indicates the importance of skin eruptions in the context of hematological malignancies.

    Over recent decades, both the incidence and prevalence of chronic inflammatory bowel disease have continued to rise in industrialized countries; the disease is frequently associated with extracutaneous involvement and comorbidity. The purpose of this work was to investigate the frequency and specificity of mucocutaneous manifestations in Crohn's disease (CD) and ulcerative colitis (UC). An extensive search in peer-reviewed journals via PubMed was performed; presented is a summary and analysis of various studies and data, including data of patients treated at our department. CD and UC are frequently associated with mucocutaneous symptoms; however, primary/specific disease-associations are exclusively seen in CD patients. These include peri-anal and -stomal fistulas and ulcerations, "metastatic" Crohn's disease as well as oral granulomatous disease. Moreover, in both CD and UC, there occur several other inflammatory skin conditions such as erythema nodosum, pyoderma gangrenosum, hidradenitis suppurativa, chronic oral aphthous disease, Sweet syndrome, pyostomatitis vegetans, and bowel-associated dermatosis-arthritis syndrome. Malnutrition syndromes (zinc and vitamin deficiencies) are only rarely observed. On skin and oral/genital mucous membranes various different inflammatory manifestations may be observed during the course of CD or UC. However, most data about a direct pathogenic relationship of the gastrointestinal and dermatologic disorders are quite heterogeneous or even contradictory. Nevertheless, knowledge of these conditions and their possible association with CD and UC could be crucial for early diagnosis and initiation of an appropriate therapy and thus be essential to prevent secondary tissue damage.

    Management of surgically placed ostomies is an important aspect of any general surgical or colon and rectal surgery practice. Complications with surgically placed ostomies are common and their causes are multifactorial. Parastomal ulceration, although rare, is a particularly difficult management problem. We conducted a literature search using MD Consult, Science Direct,OVID, Medline, and Cochrane Databases to review the causes and management options of parastomal ulceration. Both the etiology and treatments are varied.Different physicians and ostomy specialists have used a large array of methods to manage parastomal ulcers;these including local wound care; steroid creams;systemic steroids; and, when conservative measures fail, surgery. Most patients with parastomal ulcers who do not have associated IBD or peristomal pyoderma gangrenosum (PPG) often respond quickly to local wound care and conservative management. Patients with PPG,IBD,or other systemic causes of their ulceration need both systemic and local care and are more likely to need long term treatment and possibly surgical revision of the ostomy. The treatment is complicated, but improved with the help of ostomy specialists.

    Full Text Available Infection with hepatitis viruses, especially B and C, is a major public health problem in many countries. One hundred consecutive patients with these infections were studied for cutaneous abnormalities. Females were more commonly affected. Recurrent/chronic vascular changes (92% , urticaria (72%, leucocytoclastic vasculitis (36%, erythema nodosum (28%, Gianotti-Crosti syndrome (12%, lichen planus (8%, pyoderma gangrenosum (2 patients and dermatomyositis like syndrome (1 patient were the prominent cutaneous abnormalities noted in patients with hepatitis B. Likewise, the prominent skin abnormalities notes in hepatitis â€" C Patients were vascular changes (82.2%, chronic urticaria (60.0%, xerosis of skin (56.6%, leucocytoclastic vasculitis (40%, erythema multiforme (23.3%, Sjogren’s syndrome (13.2%, recurrent erythema nodosum (19.8% and Behcet’s syndrome in a single case. Extensive subcutaneous fat atrophy of the face in one case and diffuse hyperpigmentation in 5 cases were the two interesting features noted in out patients, which have not been reported earlier. The pertinent literature is briefly reviewed in the light of above findings.

Studies with periodontal fibroblasts indicate that attachment to these structures increases the endogenous secretion of multiple growth factors and cell proliferation. Pre-clinical and clinical studies indicate that cutaneous wounds benefit from treatment with amelogenins. A randomized controlled trial (RCT involving patients with hard-to-heal venous leg ulcers (VLUs (ie, ulcers with a surface area ≥10 cm2 and duration of ≥6 months showed that the application of amelogenin (Xelma®, Molnlycke Health Care, Gothenburg, Sweden as an adjunct treatment to compression results in significant reduction in ulcer size, improvement in the state of ulcers, reduced pain, and a larger proportion of ulcers with low levels of exudate, compared with treatment with compression alone. Amelogenin therapy was also shown to be safe to use in that there were no significant differences in adverse events noted between patients treated with amelogenin plus compression and those treated with compression alone. Case study evaluations indicate that the benefits of amelogenin therapy demonstrated in the RCT are being repeated in “real life” situations and that amelogenin therapy may also have a role to play in the treatment of other wound types such as diabetic foot ulcers.Keywords: extracellular matrix, amelogenin, venous leg ulcers, diabetic foot ulcers, pyoderma gangrenosum

  4. Streptococcal Immunity Is Constrained by Lack of Immunological Memory following a Single Episode of Pyoderma.

    Manisha Pandey

    2016-12-01

    Full Text Available The immunobiology underlying the slow acquisition of skin immunity to group A streptococci (GAS, is not understood, but attributed to specific virulence factors impeding innate immunity and significant antigenic diversity of the type-specific M-protein, hindering acquired immunity. We used a number of epidemiologically distinct GAS strains to model the development of acquired immunity. We show that infection leads to antibody responses to the serotype-specific determinants on the M-protein and profound protective immunity; however, memory B cells do not develop and immunity is rapidly lost. Furthermore, antibodies do not develop to a conserved M-protein epitope that is able to induce immunity following vaccination. However, if re-infected with the same strain within three weeks, enduring immunity and memory B-cells (MBCs to type-specific epitopes do develop. Such MBCs can adoptively transfer protection to naïve recipients. Thus, highly protective M-protein-specific MBCs may never develop following a single episode of pyoderma, contributing to the slow acquisition of immunity and to streptococcal endemicity in at-risk populations.

    2012-01-01

    Full Text Available Microscopic forms of colitis have been described, including collagenous colitis, a possibly heterogeneous disorder. Collagenous colitis most often appears to have an entirely benign clinical course that usually responds to limited treatment. Sometimes significant extracolonic disorders, especially arthritis, spondylitis, thyroiditis and skin disorders, such as pyoderma gangrenosum, dominate the clinical course and influence the treatment strategy. However, rare fatalities have been reported and several complications, some severe, have been attributed directly to the colitis. Toxic colitis and toxic megacolon may develop. Concomitant gastric and small intestinal inflammatory disorders have been described including celiac disease and more extensive collagenous inflammatory disease. Colonic ulceration has been associated with the use of nonsteroidal anti-inflammatory drugs, while other forms of inflammatory bowel disease, including ulcerative colitis and Crohn disease, may evolve directly from collagenous colitis. Submucosal ‘dissection’, colonic fractures, or mucosal tears and perforation, possibly from air insufflation during colonoscopy, have been reported. Similar changes may result from increased intraluminal pressures that may occur during radiological imaging of the colon. Neoplastic disorders of the colon may also occur during the course of collagenous colitis, including colon carcinoma and neuroendocrine tumours (ie, carcinoids. Finally, lymphoproliferative disease has been reported.

  6. Recent Advances In Topical Therapy In Dermatology

    2003-01-01

    Full Text Available With changing times various newer topical agents are introduced in the field of dermatology. Tacrolimus and pimecrolimus are immunisuppressants, which are effective topically and are tried in the management of atopic dermatitis as well as other disorders including allergic contact dermatitis, atrophic lichen planus, pyoderma gangrenosum. Imiquimod, an immune response modifier, is presently in use for genital warts but has potentials as anti- tumour agent and in various other dermatological conditions when used topically. Tazarotene is a newer addition to the list of topical reginoids, which is effective in psoriasis and has better effect in combination with calcipotriene, phototherapy and topical costicosteroids. Tazarotene and adapelene are also effective in inflammatory acne. Calcipotriol, a vitamin D analogue has been introduced as a topical agent in the treatment of psoriasis. Steroid components are also developed recently which will be devoid of the side effects but having adequate anti-inflammatory effect. Topical photodynamic therapy has also a wide range of use in dermatology. Newer topical agents including cidofovir, capsaicin, topical sensitizers, topical antifungal agents for onychomycosis are also of use in clinical practice. Other promising developments include skin substitutes and growth factors for wound care.

    Nwabudike Lawrence Chukwudi

    2013-04-01

    Full Text Available The Koebner phenomenon or isomorphic phenomenon is described in dermatology texts as the production of lesions of the original disease, in clinically uninvolved skin, following trauma. The lesions are located at the site of trauma and evidence of a traumatic causation is the linear arrangement of some of the lesions, such as in the case of lichen planus. Other disorders known to exhibit the Koebner phenomenon include psoriasis and vitiligo. A number of other diseases are associated with the Koebner phenomenon. Pathergy is a phenomenon of pustule production following trauma, which occurs in certain disorders such as Pyoderma gangrenosum and Behçet?s disease. In some disorders such as impetigo and verruca vulgaris, inoculation may give the appearance of the Koebner phenomenon. A case of pityriasis rosea and Koebner phenomenon at the site of routine blood assay is described in this work. This author has not thus far encountered any description of the Koebner reaction in relation to pityriasis rosea in the literature, but, perhaps, with this report, other physicians will be more open to this possibility and actually uncover similar cases.

    Full Text Available Skin necrosis and limb gangrene are occasional thrombotic manifestations of anticoagulation therapy. We report a man heterozygous for the Factor V Leiden (FVL mutation, and with a history of recurrent deep venous thrombosis, who initially presented with a necrotic skin lesion of the right flank while on warfarin therapy with a therapeutic international normalized ratio. Warfarin was discontinued and he received intravenous heparin. Thereafter he developed thrombocytopenia and pedal erythema and was diagnosed with heparin-induced thrombocytopenia (HIT. Heparin was replaced with argatroban. He ultimately underwent bilateral below-knee amputations for the thrombotic complications of the HIT. The initial necrotic lesion healed with antibiotics and wound care. Pathologic examination of multiple biopsy specimens revealed two separate lesions. One was necrotic tissue infiltrated with methicillin resistant Staphylococcus aureus having features of ecthyma gangrenosum. The second showed thrombotic changes consistent with HIT. The case illustrates the differential diagnosis of skin necrosis and limb gangrene in patients on warfarin and heparin, and also the clinical complexities that can occur in a FVL heterozygote.

    Full Text Available Kimberly Doctor, Dorin T Colibaseanu Section of Colon and Rectal Surgery, Mayo Clinic, Jacksonville, FL, USA Abstract: Enterostomal formation remains a necessary part of multiple types of surgeries. Stomal difficulties can be a source of frustration for patients; however, a properly functioning stoma in a patient educated in its care can result in a highly functional individual, with a high quality of life, comparable to a person without a stoma. Correct surgical technique is vital to creating a stoma that is sufficiently everted, and in a good anatomical location. Loop ileostomies have a higher chance of complications, thus care in their formation is especially important. Systemic disease (inflammatory conditions, and autoimmune diseases especially as well as local conditions (pyoderma gangrenosum, infections, and fistulas, among others can be the causes for difficult-to-treat peristomal complications. Accurate diagnosis is essential in order to be able to address the underlying disease. Choosing the appropriate products to care for the stoma is often a process of trial and error, and is best done under the guidance of an enterostomal therapist. This is especially true for stomas in overweight individuals or stomas that have become flush with the skin with time and changing body habitus. Inattention to care can result in problems that range from simple mucocutaneous separations (separation of the bowel edge from the surrounding skin to large and difficult-to-heal ulcers. This article provides a systematic review of the most common challenges that patients with stoma are faced with, and offers solutions based on up-to-date review of the literature.

    Full Text Available Abstract Background Ecthyma gangrenosum (EG manifests as a skin lesion affecting patients suffering extreme neutropenia and is commonly associated with Pseudomonas aeruginosa in immunocompromised patients. Leukocyte adhesion deficiency I (LAD I which count among primary immunodeficiency syndromes of the innate immunity, is an autosomal recessive disorder characterized in its severe phenotype by a complete defect in CD18 expression on neutrophils, delayed cord separation, chronic skin ulcers mainly due to recurrent bacterial and fungal infections, leucocytosis with high numbers of circulating neutrophils and an accumulation of abnormally low number of neutrophils at sites of infection. Case Presentation We report at our knowledge the first case of a child affected by LAD-1, who experienced during her disease course a multi-bacterial and fungal EG lesion caused by fusarium solani. Despite targeted antibiotics and anti-fungi therapy, the lesion extended for as long as 18 months and only massive granulocytes pockets transfusions in association with G-CSF had the capacity to cure this lesion. Conclusion We propose that granulocytes pockets transfusions will be beneficial to heal EG especially in severely immunocompromised patients.

    Thalidomide is reported to have therapeutic utility in the treatment of pyoderma gangrenosum, Behçet's disease, aphthous ulcers, and skin wounds. We investigated the effect of thalidomide on human keratinocyte proliferation and migration, two early and critical events in the re-epithelialization of skin wounds. Thalidomide at concentrations less than 1 microM did not affect keratinocyte viability. Using a thymidine incorporation assay, we found that thalidomide, at therapeutic concentrations, induced more than a 2. 5-fold increase in the proliferative potential of the cells. Keratinocyte migration was assessed by two independent motility assays: a colloidal gold assay and an in vitro scratch assay. At optimal concentrations, thalidomide increased keratinocyte migration on a collagen matrix more than 2-fold in the colloidal gold assay and more than 3-fold in the scratch assay over control. Although pro-migratory, thalidomide did not alter the level of metalloproteinase-9 secreted into culture medium. Thalidomide did, however, induce a 2-4-fold increase in keratinocyte-derived interleukin-8, a pro-migratory cellular autocrine factor. Human keratinocyte migration and proliferation are essential for re-epithelialization of skin wounds. Interleukin-8 increases human keratinocyte migration and proliferation and is chemotactic for keratinocytes. Therefore, thalidomide may modulate keratinocyte proliferation and motility by a chemokine-dependent pathway.

    Full Text Available One hundred new cases of pyodenna attending King George Hospital, Vishakhapatnam were investigated bacteriologically with antibiotic sensitivity of all the strains isolated and phage typing of coagulm positive staphylocci. Among these 50 had impetigo and 15 each ahd furunculosis and fouiculitis. The remaining included various other clinical entities. Children under 10 years were observed to have high incidence of pyoderma. A total of 88 strains of staphylococci (77 coagulase positive and 11 coagulase negative strains 25 strains of beta haemolytic streptococci and 3 strains of Klebsiella were isolated. Staphylococci were found to be the commonest aetiological agents either single or in association with other organisms. Of the 76 strains of coagulase positive staphylococci 32 strains were not phage typable and among the 44 typable strains 17 (38% belonged to group III and 15 (36.5% to mixed group. Coagulase positive staphylococci showed high sensitivity to garamycin, kanamycin and erythromycin and high resistance to penicillin and streptomycin. Multiple drug resistance was also high among these strains. Coagulase negative staphylococci were found to be more sensitive with less incidence of multiple drug resistance. Most of multiple drug resistant strains belonged to group III phage types. Beta haemolytic streptococci were found to be highly sensitive to all the antibiotics tested.

  15. Vasculitis in the autoinflammatory diseases.

    This article addresses the prevalence and relationship between autoinflammatory diseases and vasculitis. Autoimmune diseases (AIDs) are a group of syndromes characterized by episodes of unprovoked inflammation due to dysregulation of the innate immune system. Despite the common occurrence of rashes and other skin lesions in these diseases, vasculitis is reported in only a few. On the other hand, neutrophilic dermatoses are more prevalent. Large vessel vasculitis is reported in patients with Behcet's and Blau's syndromes. Small and medium size vasculitides are reported in familial Mediterranean fever mainly as Henoch-Schonlein purpura and polyarteritis nodosa, respectively. It is rarely described in hyper IgD with periodic fever syndrome, cryopyrin associated periodic syndromes, TNF receptor-associated periodic syndrome, deficiency of interleukin-1 receptor antagonist and pyoderma gangrenosum and acne syndrome. In most AID where bones and skin are mainly involved (CRMO, Majeed syndrome, Cherubism and DITRA) - vasculitis has not been described at all. In AID small vessel vasculitis affects mainly the skin with no involvement of internal organs. In AID, neutrophilic dermatoses are more common and prominent than vasculitis. This may reflect a minor role for interleukin-1 in the pathogenesis of vasculitis. The rarity of vasculitis in AID suggests that in most reported cases its occurrence has been probably coincidental rather than being an integral feature of the disease.

    Blinding is the process of keeping treatment assignment hidden and is used to minimise the possibility of bias. Trials at high risk of bias have been shown to report larger treatment effects than low-risk studies. In dermatology, one popular method of blinding is to have independent outcome assessors who are unaware of treatment allocation assessing the endpoint using digital photographs. However, this can be complex, expensive and time-consuming. The objective of this study was to compare the effect of blinded and unblinded outcome assessment on the results of the STOP GAP trial. The STOP GAP trial compared prednisolone to ciclosporin in treating pyoderma gangrenosum. Participants' lesions were measured at baseline and at 6 weeks to calculate the primary outcome, speed of healing. Independent blinded assessors obtained measurements from digital photographs using specialist software. In addition, unblinded treating clinicians estimated lesion area by measuring length and width. The primary outcome was determined using blinded measurements where available, otherwise unblinded measurements were used (method referred to as trial measurements). In this study, agreement between the trial and unblinded measurements was determined using the intraclass correlation coefficient (ICC). The STOP GAP trial's primary analysis was repeated using unblinded measurements only. We introduced differential and nondifferential error in unblinded measurements and investigated the effect on the STOP GAP trial's primary analysis. Eighty-six (80%) of the 108 patients were assessed using digital images. Agreement between trial and unblinded measurements was excellent (ICC = 0.92 at baseline; 0.83 at 6 weeks). There was no evidence that the results of the trial primary analysis differed according to how the primary outcome was assessed (p value for homogeneity = 1.00). Blinded digital image assessment in the STOP GAP trial did not meaningfully alter trial conclusions compared with

    Full Text Available A 50-year-old Japanese woman consulted the emergency department of our hospital for bleeding due to an intractable postoperative wound on the lower abdomen; the postoperative wound was owing to a laparoscopic cholecystectomy performed 1 year previously for acute cholecystitis. She presented with a painful ulcer on her right lower abdomen. She also presented with multiple scars, skin grafts on the extremities, and a missing left lower leg, the causes for all of which were unexplained. The results of her blood test were normal, except for the hemoglobin level. Histology of the skin biopsy specimen from the ulcer did not show any specific findings. The previous surgeon who had performed the laparoscopic cholecystectomy revealed that surgical wound dehiscence had occurred during her admission. After a body restraint had been applied, the ulcer improved. Medical records indicated that she had been admitted to the department of plastic surgery at our hospital for skin grafting of a leg ulcer. During that admission, she refused to consult with the department of psychiatry, although the staff suspected mental disorders. Therefore, we diagnosed her with cutaneous Munchausen syndrome. After vacuum-assisted closure (VAC therapy had been performed to prevent her from traumatizing the ulcer again, it rapidly became granulated and reepithelialized. Munchausen syndrome is characterized by feigning physical symptoms to seek attention. Patients self-inflict numerous lesions, keep getting admitted to different hospitals, and feign acute illness, usually spectacular diseases. VAC therapy may be effective for preventing patients with cutaneous Munchausen syndrome from traumatizing their wounds.

    A vascular cause is found in around 85% of leg ulcer patients, but non-vascular causes are also observed. Their diagnosis is based on a set of clinical arguments and skin biopsy with histological analysis. The aim of this study was to analyze the results of these biopsies and to find common criteria for ulcers whose skin biopsies had led to the diagnosis of a non-vascular ulcer. A retrospective study was carried out on the analysis of 143 skin biopsies of leg ulcers. The reasons for the biopsy were mainly atypical clinical signs and/or the lack of improvement in care after 6 months, as advocated by the French health authorities. The skin biopsies led to a diagnosis of non-vascular ulcer in 4.9% of cases (7/143), including skin cancer (n=5, 3.5%), cutaneous leishmaniasis (n=1, 0.7%) and Pyoderma gangrenosum (n=1, 0.7%). The univariate statistical analysis revealed that an elevated rim and abnormal excessive granulation tissue were significantly more frequently found in these ulcers. All patients with a positive skin biopsy had associated vascular involvement. This study found a 5% rate of non-vascular causes of ulcers, mainly skin cancer. Elevated rims and abnormal excessive granulation tissue were the unusual features most commonly found in these ulcers. All patients whose skin biopsy revealed a non-vascular cause had associated vascular involvement. This information confirms the need to perform a skin biopsy, even in the presence of a vascular disease. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

  1. Histopathological aspects of neutrophilic dermatoses: Investigation of 38 cases and review of the literature

    2016-01-01

    Full Text Available Introduction: Neutrophilic dermatosis (ND is a heterogeneous group of diseases with various etiologies and clinical presentations. NDs may clinically present as papule, vesiculopustule, plaque, and nodule of the skin, but they all share the common feature of neutrophilic predominance in the skin. Histological examination of patients with suspected ND is a key step for making the proper diagnosis. Patients and Methods: The aim of this article was to investigate histopathological aspects of different NDs. We obtained our data from medical records of patients at Razi dermatology hospital, between 2012 and 2014. Thirty-eight biopsy records coded under the term of any ND, including Sweet's syndrome (SS, pyoderma gangrenosum (PG, skin lesions of Behcet's disease, neutrophilic drug eruption, amicrobial pustulosis of the folds, pustular vasculitis of the hands, and undetermined ND were recruited in our study. The specimens were evaluated regarding inflammatory reaction pattern, epidermal/adnexal changes, and dermal changes. Results: Most common NDs in our study were PG (42.1% followed by SS (21.1%. The most common pattern of inflammatory reaction was superficial perivascular and interstitial dermal inflammation in 44.7% of the patients. Exocytosis of neutrophils into epidermis, hair follicle, and eccrine gland was seen in 71%, 18.5%, and 28.9% of the specimens, respectively. Ulceration was only seen in ten PG specimens. Dermal fibrosis and vascular proliferation were reported in all PG patients. Conclusion: The prevalence of some histopathological findings in different types of ND was significantly different. These features seem helpful in distinguishing between different NDs.

  2. Calciphylaxis and Martorell Hypertensive Ischemic Leg Ulcer: Same Pattern - One Pathophysiology.

    2016-01-01

    This review presents a closer look at four diseases which are probably closely related to one another pathophysiologically: (a) calciphylaxis (distal pattern); (b) calciphylaxis (proximal pattern); (c) Martorell hypertensive ischemic leg ulcer; (d) calciphylaxis with normal renal and parathyroid function (synonym: eutrophication). The four diseases have largely the same risk factors: (1) arterial hypertension, (2) diabetes mellitus (types 1 and 2), (3) secondary or tertiary hyperparathyroidism (in end-stage kidney disease) and (4) oral anticoagulation with vitamin K antagonists. They share the same clinical patterns: necrotizing livedo, skin infarctions at typical locations and acral gangrene in calciphylaxis. They also share the same histopathology: ischemic subcutaneous arteriolosclerosis and small-artery disease and 'miniaturizing' Mönckeberg medial calcinosis. The treatment concept for the acute phase of the diseases is also broadly similar. In addition to an optimized control of the cardiovascular risk factors, a proactive wound approach (necrosectomy, negative pressure wound treatment with vacuum dressings, and early skin grafts supported by systemic antibiotic therapy) leads most rapidly and effectively to a reduction of the initially severe wound pain, and finally to complete healing of the wound. Oral anticoagulation with vitamin K antagonists should be stopped. In extensive cases, the use of intravenous sodium thiosulfate is recommended. All four diagnoses are little known in the medical schools of most countries. The need to improve familiarity with these four closely related disorders is therefore great. In particular, the risk of confusion with pyoderma gangrenosum is a major diagnostic problem which can lead to false and even damaging treatment. © 2016 S. Karger AG, Basel.

    Skin and joint manifestations are part of the clinical spectrum of many disorders. Well-known associations include psoriatic arthritis and arthritis associated with autoimmune connective tissue diseases. This review focuses on less common associations where skin lesions can provide easily accessible and valuable diagnostic clues, and directly lead to the specific diagnosis or limit the list of possibilities. This may also affect health care resources as diagnostic tests are often low-specific, highly expensive and poorly available. This group of diseases can be divided into two subsets, based on the presence/absence of fever, and then further classified according to elementary skin lesions (macular, urticarial, maculo-papular, vesico-bullous, pustular, petechial and nodular). In most instances joint involvement occurs as peripheral migrating polyarthritis. Erythematosus macular or urticarial rashes occur in most febrile disorders such as monogenic autoinflammatory syndromes, Schnitzler's syndrome, Still's disease and rheumatic fever and afebrile diseases as urticarial vasculitis. Pustular rash may be observed in chronic recurrent multifocal osteomyelitis (CRMO) and pyogenic arthritis with pyoderma gangrenosum and acne (PAPA) syndrome (both febrile) as well as in Behcet's disease and Synovitis, acne, pustulosis, hyperostosis and osteitis syndrome (both non-febrile). Papular lesions are typical of secondary syphilis, sarcoidosis, interstitial granulomatous dermatitis, papular petechial of cutaneous small-vessel vasculitis and nodular lesions of polyarteritis nodosa and multicentric reticulohistiocytosis all of which are afebrile. Differential diagnosis includes infections and drug reactions which may mimic several of these conditions. To biopsy the right skin lesion at the right time it is essential to obtain relevant histological information. © 2013 European Academy of Dermatology and Venereology.

  4. JAK3 as an Emerging Target for Topical Treatment of Inflammatory Skin Diseases.

    Directory of Open Access Journals (Sweden)

    Ana Karina Alves de Medeiros

    Full Text Available The recent interest and elucidation of the JAK/STAT signaling pathway created new targets for the treatment of inflammatory skin diseases (ISDs. JAK inhibitors in oral and topical formulations have shown beneficial results in psoriasis and alopecia areata. Patients suffering from other ISDs might also benefit from JAK inhibition. Given the development of specific JAK inhibitors, the expression patterns of JAKs in different ISDs needs to be clarified. We aimed to analyze the expression of JAK/STAT family members in a set of prevalent ISDs: psoriasis, lichen planus (LP, cutaneous lupus erythematosus (CLE, atopic dermatitis (AD, pyoderma gangrenosum (PG and alopecia areata (AA versus healthy controls for (pJAK1, (pJAK2, (pJAK3, (pTYK2, pSTAT1, pSTAT2 and pSTAT3. The epidermis carried in all ISDs, except for CLE, a strong JAK3 signature. The dermal infiltrate showed a more diverse expression pattern. JAK1, JAK2 and JAK3 were significantly overexpressed in PG and AD suggesting the need for pan-JAK inhibitors. In contrast, psoriasis and LP showed only JAK1 and JAK3 upregulation, while AA and CLE were characterized by a single dermal JAK signal (pJAK3 and pJAK1, respectively. This indicates that the latter diseases may benefit from more targeted JAK inhibitors. Our in vitro keratinocyte psoriasis model displayed reversal of the psoriatic JAK profile following tofacitinib treatment. This direct interaction with keratinocytes may decrease the need for deep skin penetration of topical JAK inhibitors in order to exert its effects on dermal immune cells. In conclusion, these results point to the important contribution of the JAK/STAT pathway in several ISDs. Considering the epidermal JAK3 expression levels, great interest should go to the investigation of topical JAK3 inhibitors as therapeutic option of ISDs.

    Tattoos are defined as the introduction of exogenous pigments into the dermis in order to produce a permanent design. This process may occur unintentional or may be deliberately administered for cosmetic or medical reasons. Tattoos have been around for over 5000 years and over time have evolved to represent a common cosmetic practice worldwide. Currently, adverse reactions are relatively rare and generally unpredictable and predominantly include immune-mediated reactions and skin infections. Along with better healthcare standards and more stringent public health mandates such as the provision of disposable needles, major infectious complications related to hepatitis and human retroviral infections have decreased significantly. When they do occur, skin infections are most frequently associated with Staphylococcus aureus or Streptococcus pyogenes. The aim of this study is to review the types and rates of medical complications of permanent tattoos. PubMed search and search dates were open ended. Acute local inflammation is the most common complication, but infections, allergic contact dermatitis, and other inflammatory or immune responses that are not well-characterized may occur. As many patients with immune reactions to tattoos do not react on skin or patch testing, it is postulated that the antigens contained in dyes or pigments are such small molecules that they need to be haptenized in order to become immunogenic. Red ink is associated more frequently with long-term reactions, including granulomatous and pseudolymphomatous phenomena or morphea-like lesions and vasculitis. Exacerbation of preexisting psoriasis, atopic dermatitis, and pyoderma gangrenosum may occur after tattooing. There is no well-defined association between cancer and tattoos. The treatment of tattoo-related complications may include local destructive measures (cryotherapy, electro-surgery, dermabrasion, chemical destruction, ablative laser destruction), surgical excision, and thermolysis of the

    Nocardia brasiliensis is a very rarely reported cause of chronic phagedenic ulcerations. We report the case of an elderly woman who developed such an infection after falling on her right leg on the road in the Bresse country (an essentially agricultural and bovine-cattle breading region) and developed a chronic phagedenic ulcer secondarily complicated by nodular lymphangitis of the thigh. A 75 year-old woman fell on her right leg on the side of the main road outside her hamlet in the Bresse country and secondarily developed a chronique phagedenic ulceration. We first considered her as suffering from pyoderma gangrenosum. A complete scanning only revealed an autoimmune thyroiditis and a rapidly healing gastric ulceration, and none of the treatments, either local or systemic, helped the skin condition to heal. After 3 weeks of application of a local corticoid ointment, the patient developed fever, general malaise, an exacerbation of her wound and an infiltration of the skin round her knee, together with nodular lymphangitic dissemination. A supplementary bacterial swab disclosed massive proliferation of a slow-growing Gram-positive bacillus, which proved to be Nocardia brasiliensis, together with a methicillino-sensitive Staphylococcus aureus. The treatment with sulfamethoxazole-trimetoprim gave a rash after 12 hours and was changed to amoxicillin and clavulanic acid, which rapidly proved to be permanently effective. The revelation of this particular slow-growing bacteria is difficult and requires bacterial swabs. Nocardia brasiliensis is relatively rare in primary skin ulcerations and we discuss the reasons why an elderly women should find this bacteria on the road outside her hamlet in the French countryside. This particular infectious condition requires general scanning, to make sure that the primary skin condition does not extend to other organs. We review the therapeutical options for patients who exhibit allergic reactions to the classically effective

    Full Text Available HIV seropositivity rate of 14 percent was observed amongst STD cases. Heterosexual contact with prostitutes was the main risk factor. Fever, anorexia, weight loss, lymphadenopathy and tuberculosis were useful clinical leads. Genital ulcers, especially chancroid, were common in seropositivies. Alopecia of unknown cause, atypical pyoderma, seborrhea, zoster, eruptive mollusca and sulfa-induced erythema multiforme were viewed with suspicion in high risk groups. Purpura fulminans, fulminant chancroid, vegetating pyoderma and angioedema with purpura were unique features noted in this study.

    In 100 dogs with 4 inflammatory dermatologic diseases, buffy coat preparations from EDTA-treated blood samples were examined cytologically. Fifty-four dogs had atopy, 26 had flea-bite hypersensitivity, 17 had sarcoptic mange, and 3 had food allergy. Twenty-eight dogs had 2 or more concurrent skin diseases; most of these had secondary pyoderma. Dogs did not have mast cell tumors. Thirteen samples contained 1 or more mast cells/4 slides reviewed. This study revealed that dogs with inflammatory skin diseases can have a few to many mast cells evident on cytologic examination of buffy coat preparations.

    The aim of this study was to investigate the presence of canine immunoglobulins (Ig) G against Demodex proteins in the sera of healthy dogs and of dogs with juvenile generalized demodicosis (CanJGD) with or without secondary pyoderma. Demodex mites were collected from dogs with CanJGD. Protein concentration was measured and a western blot technique was performed. Pooled sera from healthy dogs reacted mainly with antigen bands ranging from 55 to 72 kDa. Pooled sera from dogs with CanJGD without secondary pyoderma reacted either with 10 kDa antigen band or 55 to 72 kDa bands. Pooled sera from dogs with CanJGD with secondary pyoderma reacted only with a 10 kDa antigen band. The results of this study suggest that both healthy dogs and dogs with CanJGD develop a humoral response against different proteins of Demodex canis. Copyright © 2015 Elsevier Ltd.

    Full Text Available We describe a case of a 65-year-old male presenting with a large plaque with a rolled-out interrupted margin, atrophic center, and island of normal skin over the left arm. It grew peripherally with central healing, and there was a history of recurrence after inadequate excision. Investigations ruled out other clin­ical mimickers; namely, squamous cell carcinoma, lupus vulgaris, botryomycosis, and blastomycosis-like pyoderma. Histopathological sections showed irregularly shaped craters filled with keratin and epithelial pearl but no evidence of granuloma or cellular atypia. Clinico­pathological correlation proved the lesion to be keratoacanthoma centrifugum marginatum (KCM, a rare variant of keratoacanthoma, which spreads centrifugally, attains a huge size, and never involutes spontaneously. Treatment of KCM has been a problem always and, in our case, systemic retinoid (acitretin for three months proved ineffective. The patient also had a history of recurrence following surgical intervention previously, necessitating wide excision to achieve complete clearance of tumor cells. Hence, after failure of retinoid therapy, the decision of excision with a 1-centimeter margin was taken and the large defect was closed by a split thickness skin graft. The graft uptake was satisfactory, and the patient is being followed-up presently and shows no signs of recurrence after six months, highlighting wide local excision as a useful treatment option.

    Demodex canis is a natural inhabiting mite of canine skin. Immunological disorder or genetic disorder induces the Demodex population to proliferate vigorously resulting in generalized demodicosis with consequent chronic immunosuppression. Signs of generalized demodicosis include alopecia, crysting, erythema, secondary pyoderma etc. Amitraz, an acaricide, is used conventionally for the treatment of generalized demodicosis. In many instances, the disease relapses due to the residual immunosuppression. The need of an immunorestorative therapy has been urged in generalized demodicosis. Two immunorestorative drugs, namely, Immuplus, a herbal drug, and T11TS, a sheep erythrocyte surface glycoprotein, has been used in two separate groups of dogs having generalized demodicosis and receiving Amitraz treatment. It was observed that though Amitraz treated group responded to the therapy showing increased E-rosettes and nonspecific cytotoxic efficacy of T-lymphocytes and decrease in phagocytic potential of macrophages, the groups treated with the immunotherapeutics like Immuplus and T11TS, responded better. However, the group treated with T11TS showed best recovery. These results emphasize the need for an immunorestorative therapy in generalized demodicosis and provide data in favor of T11TS as a better immunomodulator in comparison to Immuplus.

    Staphylococcus pseudintermedius is a leading aetiologic agent of pyoderma and other body tissue infections in dogs and cats. In recent years, an increased prevalence of methicillin-resistant S. pseudintermedius (MRSP) has been reported. Isolation of MRSP in serious infections poses a major therapeutic challenge as strains are often resistant to all forms of systemic antibiotic used to treat S. pseudintermedius -related infections. This study investigates the occurrence of MRSP from a total of 7183 clinical samples submitted to the authors' laboratories over a 15-month period. Identification was based on standard microbiological identification methods, and by S. pseudintermedius-specific nuc polymerase chain reaction (PCR). Methicillin resistance was confirmed by PBP2a latex agglutination and mecA PCR. Susceptibility against non-beta-lactam antibiotics was carried out using a disc-diffusion method according to Clinical and Laboratory Standards Institute (CLSI) guidelines. In addition, susceptibility to pradofloxacin--a new veterinary fluoroquinolone--was also investigated. SCCmec types were determined by multiplex PCR. Staphylococcus pseudintermedius was isolated from 391 (5%) samples and 20 were confirmed as MRSP from cases of pyoderma, otitis, wound infections, urinary tract infection and mastitis in dogs only. All 20 isolates were resistant to clindamycin and sulphamethoxazole/trimethoprim. Nineteen were resistant to chloramphenicol, enrofloxacin, gentamicin, marbofloxacin and pradofloxacin; additionally, seven isolates were resistant to tetracycline. Fifteen isolates carried SCCmec type II-III, four isolates had type V and one harboured type IV. To date, only a few scientific papers on clinical MRSP strains isolated from the UK have been published, thus the results from this study would provide additional baseline data for further investigations.

    Formalin-fixed, paraffin embedded skin biopsy specimens from 44 dogs with various dermatopathies were examined for the presence of immunoglobulins (IgG, IgM, IgA) and complement (C3) by the peroxidase antiperoxidase method (PAP). Final diagnoses of the skin diseases were determined by clinical findings, fungal and bacterial cultures, skin scrapings, serum endocrinologic tests, and histologic features of cutaneous biopsies. The dermatopathies included examples of pyoderma (folliculitis/furunculosis), demodecosis, sarcoptic mange, dermatophytosis, endocrine dermatopathy, and autoimmune skin disease (AISD). In the latter category, 7 cases of pemphigus foliaceus, 1 pemphigus vulgaris, 4 discoid lupus erythematosus (DLE) and 4 examples of indeterminate AISD were examined. Immunoglobulins, C3, or both, were localized in tissue sections from AISD (15/16), pyoderma (7/11), demodecosis (4/8) sarcoptic mange (3/3), and dermatomycosis (2/3). Endocrine dermatopathy biopsies were consistently negative for Ig and C3 (0/3). The pattern of localization was most often intercellular (31/44 positive biopsies) with basement membrane immunoreactivity in 4 cases of DLE, and 1 case of indeterminate AISD. There was no consistent correlation between histologic features of hematoxylin and eosin-stained biopsies and the presence of Ig and C3. Clinical outcome was similar in both Ig and C3 positive and negative cases of non-AISD dermatitis. The high percentage (95%) of positive results in AISD biopsies indicates the usefulness and sensitivity of the PAP method for the localization of Ig and C3. Because of the high percentage of Ig localization in pyoderma (73%), biopsy specimens with extensive inflammatory skin disease are not suitable for diagnosis of AISD. The PAP method is useful in the diagnosis of AISD in biopsy specimens with minimal inflammation. Caution is warranted in the interpretation of immunoreactivity independent of clinical and histologic information.

    Despite great therapeutic advancements in psoriasis, four notable difficult-to-treat areas including the scalp, nails, intertriginous (including genitals), and palmoplantar regions, pose a challenge to both physicians and patients. Localized disease of these specific body regions inflicts a significant burden on patients' quality of life and requires an adequate selection of treatments. Areas covered: This manuscript discusses appropriate therapies and important treatment considerations for these difficult-to-treat areas based on the available clinical data from the literature. Expert opinion: Clinical trials assessing therapies for the difficult-to-treat areas have been inadequate. With the first biological clinical trial for genital psoriasis pending publication, it is with hope that other biological agents will be evaluated for region-specific psoriasis. A greater understanding of the genetic and immunologic aspects of regional psoriasis, as well as identification of unique biomarkers, will further guide management decisions. For example, the recent discovery of the IL-36 receptor gene for generalized pustular psoriasis may prove valuable for other forms of psoriasis. Ultimately, identification of the most beneficial treatments for each psoriasis subtype and difficult-to-treat area will provide patients with maximal quality of life.

    Increasing resistance of Haemophilus ducreyi to antimicrobials necessitates further trials of new antimicrobial agents for treating chancroid. Enoxacin has excellent in vitro activity against H ducreyi, and a randomised clinical trial of three doses of enoxacin 400 mg at intervals of 12 hours compared with a single dose of trimethoprim/sulphametrole (TMP/SMT) 640/3200 mg was therefore conducted. Of 169 men enrolled in the study, 86 received enoxacin and 83 received TMP/SMT. Ulcers were improved or cured in 65/73 men treated with enoxacin and 57/70 men treated with TMP/SMT. This difference was not significant. At 72 hours after treatment, H ducreyi was eradicated from ulcers of 72/77 men treated with enoxacin and of 67/74 of those treated with TMP/SMT. Patients with buboes responded equally well to both treatments. Of 100 H ducreyi strains tested, all were susceptible to both 0.25 mg/l enoxacin and the combination of 0.25 mg/l TMP and 5 mg/l SMT. Although most men treated with either regimen were cured, neither regimen appeared to be the optimum treatment for chancroid. This study shows the efficacy of enoxacin for a soft tissue infection caused by Gram negative organisms. PMID:3044978

    The TREAT facility at the Argonne National Laboratory site in the Idaho National Engineering Laboratory is being upgraded to provide capabilities for fast-reactor-safety transient experiments not possible at any other experimental facility. Principal TREAT Upgrade (TU) goal is provision for 37-pin size experiments on energetics of core-disruptive accidents (CDA) in fast breeder reactor cores with moderate sodium void coefficients. this goal requires a significant enhancement of the capabilities of the TREAT facility, specifically including reactor control, hardened neutron spectrum incident on the test sample, and enlarged building. The upgraded facility will retain the capability for small-size experiments of the types currently being performed in TREAT. Reactor building and crane upgrading have been completed. TU schedules call for the components of the upgraded reactor system to be finished in 1984, including upgraded TREAT fuel and control system, and expanded coverage by the hodoscope fuel-motion diagnostics system

    Larval therapy is used in the treatment of infected chronic wounds by allowing the removal of necrotic tissue, which induces the formation of granular tissue and the growth of healthy skin.

     

    Considering the increasing prevalence of antibiotic resistance, this type of therapy may be an effective alternative in the management of infected chronic wounds. In this article we report the use of maggot therapy using the Lucilia eximia species in 42 patients with chronic skin wounds associated to different pathologies including: venous and arterial ulcers, diabetic foot, sickle cell disease, vasculopathy, elephantiasis, Berger disease, pyoderma gangrenosum (PG, traumatic wounds, erysipelas, and hospital acquired infections.

    Bodie, Linda P

    2014-08-01

    The author presented this Presidential Address for Divison 18, Psychologists in Public Service, at the 2012 American Psychological Association Convention in Orlando, Florida. The address challenges public service psychologists to reduce the tobacco disease burden through their roles as researchers, leaders, educators, and practitioners and explains why treating tobacco use disorder is important and relevant for psychologists. The address discusses the prevalence and the resulting mortality and morbidity rates of tobacco use disorder, which call for effective evidence-based interventions that can be integrated by psychologists into other ongoing treatments. Treatment of the underserved populations, including those with serious mental illness and/or substance use disorders, presents many barriers. In addition, education and training for tobacco use disorder in undergraduate and graduate clinical psychology programs present further barriers for psychology trainees. However, progress is being made because of the numerous resources and psychology leaders who are advocates for tobacco use disorder treatment and research. Challenges for the future include increasing awareness of the importance of treatment for tobacco use disorder, finding innovative ways to increase access to comprehensive evidence-based treatment, and acknowledging that psychologists can make a difference in reducing the tobacco use disorder disease burden. Psychologists have an ethical and professional responsibility to treat tobacco use disorder.

    2012-04-01

    Urinary tract infections (UTI) in pregnant women are a relatively frequent occurrence and the spectrum of these infections ranges from lower urinary tract disease (asymptomatic bacteriuria, acute cystitis) to upper urinary tract disease (acute pyelonephritis). Anatomical and functional changes in the urinary tract in pregnancy result in significantly higher susceptibility to progression of the infection from asymptomatic bacteriuria to the stage of acute pyelonephritis. Untreated asymptomatic bacteriuria in pregnancy leads, in as much as 40%, to the development of acute pyelonephritis with all the subsequent negative effects not only for the woman herself, but particularly for the fetus. Bacteriuria in pregnancy accounts for a significantly higher number of newborns with a low birth weight, low gestational age and higher neonatal mortality rate. Therefore, it is necessary to perform screening for bacteriuria in pregnant women and, when the finding is positive, to treat this bacteriuria. The selection of an appropriate antimicrobial agent to treat urinary tract infection in pregnancy is limited by the safety of a given drug not only for the woman, but particularly for the fetus. The article provides an overview of medications that can be safely used throughout the pregnancy or only in certain stages of pregnancy. The selection of an appropriate antibiotic should always be preceded by the result of urine culture. The article presents the principles and rules for treating asymptomatic bacteriuria, acute cystitis and acute pyelonephritis in pregnant women.

    2015-06-01

    Pyoderma fistulans sinifica, also known as fox den disease, is a rare and poorly understood inflammatory disorder of the skin and subcutaneous tissues. This disorder is often mistaken for other inflammatory skin disorders and treated inappropriately. The authors describe the case of a 53-year-old male who presented to the colorectal surgery service with a longstanding diagnosis of perirectal Crohn's disease. Despite aggressive immunosuppression and numerous surgical procedures, the patient continued to have unrelenting purulent drainage from the skin of his buttocks. Following wide excision of the affected skin and subcutaneous tissues by the colorectal surgeon, the plastic surgery team reconstructed the 30 cm x 55 cm wound using a combination of local flaps and skin grafts. The initial pathology report of the excised specimen confirmed the presence of nonspecific abscesses and inflammation. Upon special request by the plastic surgery team, the sample was resectioned with the specific intent of establishing a diagnosis of fox den disease. The additional slides met the criteria for an unequivocal diagnosis of fox den disease. Immunosuppression was discontinued and the patient healed his wounds without complication. Fox den disease is often overlooked because of the obscurity of the disease and the special histological sectioning needed to establish a diagnosis. In this case, the patient was unnecessarily treated with immunosuppressive drugs for more than 3 decades because of a misdiagnosis. With increased awareness of fox den disease, perhaps its pathophysiology can be better elucidated as more patients are appropriately diagnosed and treated.

    The options for treating heart disease have greatly expanded during the course of the last 2 1/2 decades with the advent of hybrid technology. The hybrid option for treating cardiac disease implies using the technology of both interventional cardiology and cardiac surgery to treat cardiac disease. This rapidly developing technology has given rise to new and creative techniques to treat cardiac disease involving coronary artery disease, coronary artery disease and cardiac valve disease, and atrial fibrillation. It has also led to the establishment of new procedural suites called hybrid operating rooms that facilitate the integration of technologies of interventional cardiology catheterization laboratories with those of cardiac surgery operating rooms. The development of hybrid options for treating cardiac disease has also greatly augmented teamwork and collaboration between interventional cardiologists and cardiac surgeons.

    Research highlights: {yields} This paper describes a process for the metal removal from treated (CA-, ACQ- or MCQ-) wood wastes. {yields} This sulfuric acid leaching process is simple and economic. {yields} The remediated wood could be recycled in the industry. - Abstract: Chromated copper arsenate (CCA)-treated wood was widely used until 2004 for residential and industrial applications. Since 2004, CCA was replaced by alternative copper preservatives such as alkaline copper quaternary (ACQ), copper azole (CA) and micronized copper quaternary (MCQ), for residential applications due to health concerns. Treated wood waste disposal is becoming an issue. Previous studies identified a chemical process for decontaminating CCA-treated wood waste based on sulfuric acid leaching. The potential application of this process to wood treated with the copper-based preservatives (alkaline copper quaternary (ACQ), copper azole (CA) and micronized copper quaternary (MCQ)) is investigated here. Three consecutive leaching steps with 0.1 M sulfuric acid at 75 deg, C for 2 h were successful for all the types of treated wood and achieved more than 98% copper solubilisation. The different acidic leachates produced were successively treated by coagulation using ferric chloride and precipitation (pH = 7) using sodium hydroxide. Between 94 and 99% of copper in leachates could be recovered by electrodeposition after 90 min using 2 A electrical current. Thus, the process previously developed for CCA-treated wood waste decontamination could be efficiently applied for CA-, ACQ- or MCQ-treated wood.

    1993-01-01

    During field trials in the North Sea in 1992, three 20-tonne slicks of a relatively weak 30% water-in-oil emulsion were released. Two of the slicks were treated with demulsifier from spray aircraft and one of the treated slicks was sprayed with dispersant seven hours later. The experiment used flow-through fluorometry to determine oil concentrations below the control and demulsifier-treated slick. Remote sensing imagery was used to determine the area of the surface slicks. Emulsion formation was slowed down in the two demulsifier-treated slicks relative to the control slick. The demulsifier-treated slicks resulted in maximum oil concentrations in water some five times higher than the control slick and spread over a volume 10-20 times as large. The control slick was therefore more persistent on the sea surface than either of the treated slicks. 5 refs., 5 figs., 5 tabs

    When deprived of nutrients, spore forming bacilli produce endospores which are remarkably resistant to chemical sterilization. Little is known about the morphology and response fo these spores following exposure to sporocidal agents. Light microscopy does not provide sufficient resolution for studying the rupture of the spore coat and fate of intracellular material. Transmission and scanning electron microscopy offer superior resolution but require specimen preparation methods that induce physiologic as well as morphologic changes in the spores, thereby making accurate interpretation of micrographs difficult. To eliminate the possible artifacts induced by chemical fixation, dehydration, embeddment, staining and sectioning, treated and non-sporocide-treated endospores of B. thuringiensis and B. subtilis were imaged by x-ray contact microscopy using monochromatic x-rays. 6 refs., 2 figs

    This invention is directed to a process for treating biomass. The biomass is treated with a biomass swelling agent within the vessel to swell or rupture at least a portion of the biomass. A portion of the swelling agent is removed from a first end of the vessel following the treatment. Then steam is introduced into a second end of the vessel different from the first end to further remove swelling agent from the vessel in such a manner that the swelling agent exits the vessel at a relatively low water content.

    Based on an activity that DPS member Richard Schmude Jr. has been doing for years, with over 5000 children reached, DPS initiated in 2016 a pilot program entitled “Trick-or-Treat and Telescopes.” DPS encouraged its members to put out their telescopes during trick-or-treat time on Halloween, in their own lawns or in a neighbor’s lawn with better viewing (or more traffic). The program will be continued in 2017. This year should offer good viewing with a waxing gibbous moon and Saturn visible. The program was also advertised though the Night Sky Network, a consortium of astronomy clubs. The following website gives advice and connections to resources.https://dps.aas.org/education/trick-or-treat-and-telescopes acknowledged.

  10. Treating mine water

    Energy Technology Data Exchange (ETDEWEB)

    1980-10-01

    Taking into account the negative influence of mine waters with suspended matter on the natural environment on the surface, the maximum treatment of mine water underground, is proposed. It is noted that full treatment of mine water, using conventional filtration methods, would be rather expensive, but a limited treatment of mine water is possible. Such treated mine water can be used in dust suppression and fire fighting systems. Mine water treated underground should be free of any odor, with pH level ranging from 6 to 9.5, with suspended matter content not exceeding 50 mg/l and coli-titre not less than 300 cm$SUP$3. It is suggested that water treatment to produce water characterized by these parameters is possible and economical. Recommendations on construction of underground sedimentation tanks and channels, and a hydraulic system of cleaning sedimentation tanks are proposed. The settling would be stored underground in abandoned workings. (2 refs.) (In Russian)

    The effect of under treatment with adjuvant hormonal therapy, chemotherapy, or radiation was studied in elderly women with breast cancer. A prospectively maintained database was used to identify women undergoing potentially curative surgery between 1978 and 2012. The presentation, pathologic findings, treatment, and outcomes of 382 women over 70 were compared to the findings in 2065 younger patients. Subsequently, conventionally treated and under treated elderly patients were identified and their characteristics and outcomes were compared. Both young and old patients presented most frequently with mammographic findings, but older patients presented more frequently with mammographic masses while younger patients presented more frequently with mammographic calcifications. Cancers of older patients were significantly more favorable than cancers in younger patients: smaller, with more infiltrating lobular, fewer ductal carcinoma in situ, and more frequently estrogen receptor positive and fewer were poorly differentiated. Elderly patients had less axillary sampling, fewer mastectomies, less adjuvant radiation therapy, and more hormonal therapy. Fifty-one percent of the 382 elderly patients were under treated by conventional criteria. Under treated patients were more frequently in situ, better differentiated, smaller, and more often estrogen receptor positive. Forty-four percent of the under treated patients died during followup without disease recurrence. Despite under treatment, local and distant disease-free survival was comparable to patients who were not under treated.

    2008-01-01

    The aims of this study are to describe non-healing in the treated vertebral body after percutaneous vertebroplasty and analyze the influence of vacuum cleft, location, and severity of collapse on the development of nonunion cement. Of 208 patients (266 treated vertebral bodies) who were treated with percutaneous vertebroplasty from September 2002 to May 2006, 23 patients (41 treated levels) with residual or recurrent pain underwent follow-up magnetic resonance imaging (MRI) study. Retrospective chart review with analysis of preoperative and postoperative MRIs were performed in these 23 patients. In the 41 treated vertebral bodies, 22 of 41 bodies had vacuum cleft found in the preoperative MRI study. Eight of the 22 treated vertebral bodies with preoperative vacuum clefts were found to have fluid between the interface of cement and the residual bone in the collapsed vertebral bodies on follow-up MRI. The adjacent discs of these treated vertebral bodies were upward/downward displaced. The endplate of the adjacent vertebral body exhibited fibrotic change. Treated bodies with vacuum clefts and level A location (T9, T11, T12, and L1) had higher probability of developing nonunion of the cement with statistical significance. The probability of nonunion cement in severe collapsed bodies might be higher than that of union cement in mild collapsed ones, but was not statistically significant. Fluid sign in the treated body represents unhealed bone-cement interface. The location of the treated vertebral body and existence of vacuum cleft in the treated bodies may be important factors influencing the nonunion of cement. (orig.)

    Asymptomatic bacteriuria (ABU) should be treated only in pregnant women and before urological procedures that breach the mucosa. In all other clinical settings, treatment of ABU is not beneficial and only contributes to antibiotic-associated morbidity and the selection of antibiotic resistance; therefore, screening and treatment are not recommended.

    Perez-Ruiz, Fernando; Moreno-Lledó, Aitana; Urionagüena, Irati; Dickson, Alastair J

    2018-01-01

    The treat-to-target (T2T) approach has been successfully implemented in a number of diseases. T2T has been proposed for rheumatic diseases such as RA, spondyloarthritis, lupus, and recently for gout. The level of evidence for such approaches differs from one condition to the other (moderate to high for hyperlipidaemia, for example). Practice is based on the best available evidence at any time, and in absence of good evidence for T2T in gout, some suggest a conservative only-treat-symptoms approach. Evidence suggests that not treating gout to target in the long term is overall associated with worsening outcomes, such as flares, tophi and structural damage, which is associated to loss of quality of life and mortality. Different targets have been proposed for hyperuricaemia in gout; lower than 6 mg/dl (0.36 mmol/l) for all patients, at least gout. © The Author 2018.

  4. Second malignancy in patients treated for Hodgkin's disease

    International Nuclear Information System (INIS)

    Baccarani, M; Bosi, A.; Papa, G.

    1980-01-01

    Six hundred and thirteen consecutive patients with Hodgkin's disease (HD), with a follow-up of two to ten years, were reviewed with the aim of establishing the type and frequency of second malignancies. Acute non-lymphoid leukemia developed in 2 of 152 patients treated by chemotherapy (CHT), and in 5 of 344 patients treated by CHT and radiotherapy (RT). Leukemia developed 12 to 83 months after diagnosis of HD, was always preceded by a preleukemic phase (3 to 25 months), and was always fatal (after 1 to 12 months). The karyotype of leukemic cells was studied in 4 of 7 patients and was always abnormal. Solid tumors developed in 1 of 152 patients treated by CHT, and in 4 of 344 patients treated by CHT and RT. The tumors appeared 10 to 63 months after diagnosis of HD and killed all 5 patients after 10 to 16 months. For patients treated by CHT, the actuarial frequency of leukemia and other tumors seven years after diagnosis of HD was 2.0% and 1.26%, respectively. For patients treated by CHT and RT, the figures were 2.04% and 2.26%, respectively. Second malignancies were not recorded among 117 patients treated by RT alone. These data are consistent with a relationship of acute leukemia to therapy for HD

  1. Understanding academic clinicians' intent to treat pediatric obesity.

    Science.gov (United States)

    Frankfurter, Claudia; Cunningham, Charles; Morrison, Katherine M; Rimas, Heather; Bailey, Karen

    2017-02-08

    To examine the extent to which the theory of planned behavior (TPB) predicts academic clinicians' intent to treat pediatric obesity. A multi-disciplinary panel iteratively devised a Likert scale survey based on the constructs of the TPB applied to a set of pediatric obesity themes. A cross-sectional electronic survey was then administered to academic clinicians at tertiary care centers across Canada from January to April 2012. Descriptive statistics were used to summarize demographic and item agreement data. A hierarchical linear regression analysis controlling for demographic variables was conducted to examine the extent to which the TPB subscales predicted intent to treat pediatric obesity. A total of 198 physicians, surgeons, and allied health professionals across Canada (British Columbia, Alberta, Manitoba, Saskatchewan, Nova Scotia, Ontario and Quebec) completed the survey. On step 1, demographic factors accounted for 7.4% of the variance in intent scores. Together in step 2, demographic variables and TPB subscales predicted 56.9% of the variance in a measure of the intent to treat pediatric obesity. Perceived behavioral control, that is, confidence in one's ability to manage pediatric obesity, and subjective norms, congruent with one's context of practice, were the most significant predictors of the intent to treat pediatric obesity. Attitudes and barriers did not predict the intent to treat pediatric obesity in this context. Enhancing self-confidence in the ability to treat pediatric obesity and the existence of supportive treatment environments are important to increase clinician's intent to treat pediatric obesity.

  2. Current developments in TREAT hodoscope technology

    De Volpi, A.

    1975-01-01

    The development of fuel motion monitoring is traced from its inception through present operation and into future programs. After noting the role of fuel motion studies in terms of safety assurance for the LMFBR, the history of in-pile fuel monitoring is reviewed. The operational record of the present TREAT fast neutron hodoscope is summarized with attention to various performance features. Development plans for the TREAT hodoscope are described in some detail. Application of the hodoscope has been considered for eight safety facilities other than TREAT. In addition, there is a possible role for fuel monitoring techniques to be extended to real-time ex-vessel core surveillance in operating reactors. Certain intrinsic strengths of the hodoscope technique for material monitoring are identified. The pattern of development may be characterized as an adaptation of several technologies to fit available requirements and resources

    1980-01-01

    With the deferral of the Safety Test Facility (STF), the TREAT Upgrade (TU) reactor has assumed a lead role in the US LMFBR safety test program for the foreseeable future. The functional requirements on TU require a significant enhancement of the capability of the current TREAT reactor. A design of the TU reactor has been developed that modifies the central 11 x 11 fuel assembly array of the TREAT reactor such as to provide the increased source of hard spectrum neutrons necessary to meet the functional requirements. A safety consequence of the increased demands on TU is that the self limiting operation capability of TREAT has proved unattainable, and reliance on a safety grade Plant Protection System is necessary to ensure that no clad damage occurs under postulated low-probability reactivity accidents. With that constraint, the physics design of TU provides a means of meeting the functional requirements with a high degree of confidence

    Jaundice is regarded as a mysterious disease rather than a symptom of disease in several parts of India. We describe 8 cases that underwent branding to treat jaundice and subsequently presented to our centre. The causes for jaundice in these patients included a variety of benign and malignant disorders. Our report suggests that despite being literate, strong cultural beliefs lead people to seek potentially harmful procedures like branding to treat jaundice in parts of India.

    Full Text Available Objectives: The purpose of this study is to report a case of a plexiform neurofibroma (PNF in the pelvic region treated with sweet bee venom (SBV and mountain ginseng pharmacopuncture (MGP. Methods: A 16-year-old girl was diagnosed as having PNFs, neurofibromatosis type 1, 10 years ago and she had surgery three times to remove the benign tumors, but the growth of the PNFs continued. She has been treated in our clinic with SBV and MGP two times per month from March 2010 to April 2014. SBV was injected intra-subcutaneously at the borders of the PNFs in the pelvic region, and MGP was administrated intravenously each treatment time. Results: The growths of the PNFs occurred rapidly and continued steadily before treatment. Since March 2010, she has been treated in our clinic, and the growths of the PNFs have almost stopped; further-more, the discomfort of hip joint pain has been reduced, and her general condition has improved. Conclusion: We cautiously conclude that SBV and MGP treatment has some effects that suppress the growth and the spread of the PNFs in this patient.

    2005-11-01

    Psychotherapy with same-sex couples does not differ markedly from standard couple therapies; this is also true for treating couples facing infidelity. However, same-sex couples often design their relationships differently, without tradition and formal marital contracts to prescribe behavior. Based on clinical experience and the empirical research, this article addresses the differing norms involved in affirmatively treating infidelity in gay and lesbian couples within the framework of integrative behavioral couple therapy (IBCT). Two cases illustrate the process and outcome of IBCT with same-sex couples.

    Lakshmikanthan, P; Sughosh, P; White, James; Sivakumar Babu, G L

    2017-07-01

    The performance of an anaerobic bioreactor in treating mechanically biologically treated municipal solid waste was investigated using experimental and modelling techniques. The key parameters measured during the experimental test period included the gas yield, leachate generation and settlement under applied load. Modelling of the anaerobic bioreactor was carried out using the University of Southampton landfill degradation and transport model. The model was used to simulate the actual gas production and settlement. A sensitivity analysis showed that the most influential model parameters are the monod growth rate and moisture. In this case, pH had no effect on the total gas production and waste settlement, and only a small variation in the gas production was observed when the heat transfer coefficient of waste was varied from 20 to 100 kJ/(m d K) -1 . The anaerobic bioreactor contained 1.9 kg (dry) of mechanically biologically treated waste producing 10 L of landfill gas over 125 days.

    2015-10-01

    TREAT is an air-cooled, graphite moderated, thermal, heterogeneous test facility designed to evaluate reactor fuels and structural materials under conditions simulating various types of nuclear excursions and transient undercooling situations that could occur in a nuclear reactor. After 21 years in a standby mode, TREAT is being re-activated to revive transient testing capabilities. Given the time elapsed and the concurrent loss of operating experience, current generation and advanced computational methods are being applied to begin TREAT modeling and simulation prior to renewed at-power operations. Such methods have limited value in predicting the behavior of TREAT without proper validation. Hence, the U.S. DOE has developed a number of programs to support development of benchmarks for both critical and transient operations. Extensive effort has been expended at INL to collect detailed descriptions, drawings and specifications for all aspects of TREAT, and to resolve conflicting data found through this process. This report provides a collection of these data, with updated figures that are significantly more readable than historic drawings and illustrations, compositions, and dimensions based on the best available sources. This document is not nor should it be considered to be a benchmark report. Rather, it is intended to provide one-stop shopping, to the extent possible, for other work that seeks to prepare detailed, accurate models of the core and its components. Given the nature of the variety of historic documents available and the loss of institutional memory, the only completely accurate database of TREAT data is TREAT itself. Unfortunately, disassembly of TREAT for inspection, assay, and measurement is highly unlikely. Hence the data provided herein is intended serve as a best-estimate substitute.

    2000-01-01

    Caffeine, a methilxantine drug is a component of coffee, tea, stimulants and other drinks. Caffeine inhibits phosphodiesterase leading to intracellular accumulation of cyclic AMP, blocks adenosine receptors, and increases the release of Ca 2+ . We have studied the possible effect of caffeine in DNA plasmid treated or not with stannous chloride (SnCl 2 ). Previous evaluations of the effect of caffeine on the labeling of red blood cells and plasma proteins with technetium-99m have showed a decrease of % ATI in the insoluble fraction of plasma proteins. Samples of DNA were treated with SnCl 2 (0 and 200μg/ml) in 0.8% agarose. SnCl 2 has induced break on DNA and caffeine has not showed effect on the DNA. This indicates that caffeine does not eliminate the oxidant action of SnCl 2 and does not promote break in isolated DNA plasmid. (author)

    Satoh, Kouji; Saji, Shoko; Ito, Shoko; Shimizu, Hideyuki; Saji, Hikaru; Kikuchi, Shoshi

    2014-01-01

    Throughout Asia, including Japan, rice plants are cultivated in a wide range of areas from lowlands to highlands and are frequently exposed to fog, including acid fog. Some physiological studies have shown that acid fog can be a stress factor for plants. We analyzed the gene expression profiles of rice plants treated with artificially prepared simulated acid fog (SiAF) or simulated neutral fog (SiNF) for 1 or 7 days. Microarray analysis results suggested that both the SiAF and the SiNF treatments induced the expression of genes involved in the defense and stress responses in rice plants. Induction of such genes was detected in plants treated with SiAF for 1 day, and the number of induced genes increased in plants treated with SiAF for 7 days. The genes for defense and stress responses were also induced by SiNF for 7 days, although they were not induced by SiNF for 1 day. The gene expression profiles of the SiAF-treated and the SiNF-treated plants were compared to those of plants treated with other stress factors. The comparison revealed that both SiAF and SiNF treatments have similar effects to biotic stresses and ozone stress. The genes encoding NADPH oxidase and germin, which function in apoplasts, were also induced by SiAF, SiNF and biotic stresses. These findings suggest that both the SiAF and the SiNF treatments may result in oxidative stress through the apoplastic production of reactive oxygen species.

    A case history of a 'pump and treat' system, designed to remediate chlorinated solvents and petroleum hydrocarbons in soil and groundwater resulting from historic leaking of six underground storage tanks, was described. The objective of this paper was two-fold: (1) to call into question the findings of some earlier studies which claimed that 'pump and treat' will not work to remediate impacted groundwater in a timely or cost-effective manner, and (2) to demonstrate that under certain circumstances, at some sites, groundwater 'pump and treat' may be the most appropriate, lowest cost remediation alternative. The paper also demonstrates the applicability of horizontal wells and methods to use soil venting in the saturated zone as opposed to its traditional use in the vadose zone. Details of the design parameters, system characteristics and operation are provided. 2 refs., 2 tabs

    1988-01-01

    The effects of reduction in the surface charge of red blood cells (RBCs) on regional blood flow and RBC distribution were studied in rats anesthetized with pentobarbital sodium. RBCs were treated with neuraminidase to reduce their electrophoretic mobility by 56%. Normal and neuraminidase-treated RBCs labeled with 51Cr or 111In were injected into a femoral vein while an equal volume of blood was simultaneously withdrawn from a femoral artery. More than 70% of the neuraminidase-treated RBCs injected disappeared from the circulating blood in 30 min compared with less than 2% of normal RBCs. The relative distributions of neuraminidase-treated RBCs to normal RBCs, as determined from radioactivity counting, were significantly greater than 1 in the spleen (5.65 +/- 0.97, mean +/- SD), the liver (2.84 +/- 0.21), the lung (1.48 +/- 0.31), and the kidney (1.49 +/- 0.27), indicating a preferential trapping of neuraminidase-treated RBCs in these regions. This ratio was approximately 1 in all other organs. Regional blood flows in tissues were determined with 15-micron microspheres in the control period and after the infusion of neuraminidase-treated RBCs (experimental). Experimental-to-control blood flow ratios were 0.40 +/- 0.05 in the spleen, 0.66 +/- 0.06 in the liver, 0.78 +/- 0.03 in the lung, and 0.78 +/- 0.09 in the kidneys; this ratio was approximately 1 in all other organs. An experimental-to-control blood flow ratio less than 1 indicates a reduction in blood flow; this occurred in the same organs as those with trapping of neuraminidase-treated RBCs

    Some studies have reported the use of 308-nm excimer laser therapy for treating alopecia areata (AA); however, the effectiveness of this therapy on a theoretical basis has not yet been comparatively analyzed. To determine the therapeutic effect of excimer laser therapy on AA. One alopecic patch was divided into control and treated sides in 10 patients with AA. Then, 308-nm excimer laser therapy was administered twice a week for 12 weeks. Photograph and phototrichogram analyses were performed. Photographic assessments by both dermatologists and individuals of the general population showed objective improvements after excimer laser therapy. On the treated side, the hair count and hair diameter had statistically increased after treatment. However, only the hair diameter was found to be significantly high in the treated half when it was compared with the control side. The 308-nm excimer laser has a therapeutic effect on AA, which is proven by photograph and phototrichogram analysis by a side-by-side comparison. © 2015 S. Karger AG, Basel.

    2010-01-01

    Treating dermatosis with liquid nitrogen as cryogen (substance generating cold) allows cellular destruction in more than 5 mm depth, making it indispensable to use it treating cutaneous cancers; besides that, it is cheap, easy to conserve and manage, and it is not considered flammable or toxic. Its applying retains the growth factor inside the injury, the collagen is not damaged as it is in burning by hot, there is not almost injury contraction, the perineurium is not altered, and when the tissue necrosis takes place, it retains tissue necrosis factor, helping to increase the necrosis of tissues. Taking into account the high incidence of dermatosis that can be treated with cryogen, in our consultation; we decided to generalize this treatment at the Provincial Interior Ministry Clinic. Plantar warts represent a big percent, limiting our patients in developing their working activities. This cutaneous viral disease is favored by the patients' systemic immunodepressions, hyperhidrosis and podalic disturbances. We selected the patients assisting to our extern al consultation with plantar wart clinical diagnosis in the period from September 2006 to September 2007. They signed an act of informed consent where the possible side effects are explained. Liquid nitrogen was applied with cotton applicators once a week after mechanical reduction. We made a clinical evolving evaluation fortnightly during the treatment, according to the elements and clinical characteristics referred by the patient, and proved by the physical examination carried out by the main investigator, because of the likelihood of short and long time side effects. This investigation demonstrated that cryotherapy is efficacious in treating plantar warts, since all the patients were healed in a short time period, most of them without side effects

    Cohen, Scott D; Cukor, Daniel; Kimmel, Paul L

    2016-12-07

    Anxiety is a common yet frequently overlooked psychiatric symptom in patients with ESRD treated with hemodialysis (HD). Anxiety is characterized by disruptive feelings of uncertainty, dread, and fearfulness. A variety of common medical complaints may be manifestations of an anxiety disorder, including palpitations, tremors, indigestion, numbness/tingling, nervousness, shortness of breath, diaphoresis, and fear. It is essential for the clinician to rule out specific medical conditions, including cardiovascular, pulmonary, and neurologic diseases, before ascribing these symptoms to an anxiety disorder. In addition, there is considerable overlap between the symptoms of anxiety and those of depression and uremia. This psychiatric condition has a significant adverse impact on patients' perception of quality of life. Little is known regarding the prevalence and impact of anxiety disorders in patients with ESRD treated with HD; however, many of the seemingly irrational behaviors of patients, or behaviors which place them in conflict with staff and physicians, such as behavioral noncompliance, may be the expression of an underlying anxiety disorder. In this review, we present three clinical vignettes, highlighting the impact of anxiety disorders in patients with ESRD treated with HD. Copyright © 2016 by the American Society of Nephrology.

  8. Effectiveness testing of spill-treating agents

    International Nuclear Information System (INIS)

    Fingas, M.F.; Stoodley, R.; Laroche, N.

    1990-01-01

    Laboratory effectiveness tests are described for four classes of spill-treating agents: solidifiers, demulsifying agents, surface-washing agents and dispersants. Many treating agents in these four categories have been tested for effectiveness and the results are presented. Solidifiers or gelling agents solidify oil, requiring a large amount of agent to solidify oil-ranging between 16% by weight, to over 200%. Emulsion breakers prevent or reverse the formation of water-in-oil emulsions. A newly-developed effectiveness test shows that only one product is highly effective; however, many products will work, but require large amounts of spill-treating agent. Surfactant--containing materials are of two types, surface-washing agents and dispersants. Testing has shown that an agent that is a good dispersant is conversely a poor surface-washing agent, and vice versa. Tests of surface-washing agents show that only a few agents have effectiveness of 25-40%, where this effectiveness is the percentage of heavy oil removed from a test surface. Results using the 'swirling flask' test for dispersant effectiveness are reported. Heavy oils show effectiveness values of about 1%, medium crudes of about 10%, light crude oils of about 30% and very light oils of about 90%. (author)

    2014-02-15

    Conventional wet treatment, desizing, scouring and bleaching, for grey cotton fabric involves the use of high water, chemical and energy consumption which may not be considered as a clean process. This study aims to investigate the efficiency of the atmospheric pressure plasma (APP) treatment on treating grey cotton fabric when compared with the conventional wet treatment. Grey cotton fabrics were treated with different combinations of plasma parameters with helium and oxygen gases and also through conventional desizing, scouring and bleaching processes in order to obtain comparable results. The results obtained from wicking and water drop tests showed that wettability of grey cotton fabrics was greatly improved after plasma treatment and yielded better results than conventional desizing and scouring. The weight reduction of plasma treated grey cotton fabrics revealed that plasma treatment can help remove sizing materials and impurities. Chemical and morphological changes in plasma treated samples were analysed by FTIR and SEM, respectively. Finally, dyeability of the plasma treated and conventional wet treated grey cotton fabrics was compared and the results showed that similar dyeing results were obtained. This can prove that plasma treatment would be another choice for treating grey cotton fabrics. Copyright © 2013 Elsevier Ltd. All rights reserved.

Some methods employed for treating wastewaters are examined, as well as instructions and rules actually in force in different countries of the world, for evaluating the legislative hygienic and sanitary and agronomic problems connected with the treated wastewaters use, are being collected and compared. Successively, in order to provide useful indications for the use of treated municipal wastewaters, results of long-term field researches, carried out in Puglia, regarding two types of waters (treated municipal wastewater and conventional water and two irrigation methods (drip and capillary sub-irrigation on vegetable crops grown in succession, are being reported. For each crop cycle, chemical physical and microbiological analyses have been performed on irrigation water, soil and crop samples. The results evidenced that although irrigating with waters having high colimetric values, higher than those indicated by law and with two different irrigation methods, never soil and marketable yield pollutions have been observed. Moreover, the probability to take infection and/or disease for ingestion of fruits coming from crops irrigated with treated wastewaters, calculated by Beta-Poisson method, resulted negligible and equal to 1 person for 100 millions of exposed people. Concentrations of heavy metals in soil and crops were lesser than those admissible by law. The free chlorine, coming from disinfection, found in the wastewaters used for watering, in some cases caused toxicity effects, which determined significant yield decreases. Therefore, municipal wastewaters, if well treated, can be used for irrigation representing a valid alternative to the conventional ones.

    More and more often the general dentist is finding the presence of endodontically treated teeth during his treatment planning procedure. He has to ask himself if the endo-treated tooth functions and will continue to function function successfully, when deciding which final endo-restorative procedure to apply. For this reason the dentist or the endodontist with whom he works should clinically evaluate these teeth, establish a diagnostic criteria of their success or failure and a treatment plan according to the prognosis. The purpose of this article is to offer an organized clinical view of the steps to follow when evaluating an endodontically treated tooth and how to establish a final endo-restorative plan.

    Significant amounts of chromated copper arsenate (CCA) treated wood products, such as utility poles and residential construction wood, remain in service. There is increasing public concern about environmental contamination from CCA-treated wood when it is removed from service for reuse or recycling, placed in landfills or burned in commercial incinerators. In this paper, we investigated the effects of time, temperature and sodium hypochlorite concentration on chromium oxidation and extraction of chromated copper arsenate from CCA-treated wood (Type C) removed from service. Of the conditions evaluated, reaction of milled wood with sodium hypochlorite for one hour at room temperature followed by heating at 75 degrees C for two hours gave the highest extraction efficiency. An average of 95% Cr, 99% Cu and 96% As could be removed from CCA-treated, milled wood by this process. Most of the extracted chromium was oxidized to the hexavalent state and could therefore be recycled in a CCA treating solution. Sodium hypochlorite extracting solutions could be reused several times to extract CCA components from additional treated wood samples.

    Percutaneous nephrolithotripsy (PNL) is the recommended method of surgical treatment of kidney stones of size greater than 2 cm. Trends in the development of modern urology have been steadily toward less traumatic method to treat nephrolithiasis - minimally invasive PNL. The present work aimed to explore of the possibilities of one of the modern variants of minimally invasive PNL - ultra-mini-PNL in treating nephrolithiasis. The study included 60 patients (mean age 45.6+/-7.2 years) with isolated kidney calculus, up to 2.0 cm or several stones with a total size of up to 2.5 cm. All patients were found to have 77 kidney stones, six of which had a size of 10 mm, 51 had a size of 11-15 mm and 20 had a size of 16-20 mm. 45% of patients had isolated renal pelvic stones and 28.3% had stones in the renal pelvis and lower calyx. All patients underwent ultra-mini-PNL using nephroscope size 7.5 Ch and tube size 12 Fr. The average duration of surgery from the moment of the puncture of the pyelocaliceal system to installing the nephrostomy tube was 65.4 minutes. Complete clearance of stones after single-stage ultra-mini-PNL was observed in 80% of cases. Nephrostomy tube was removed on days 2-3. The average postoperative hospital stay was 5.1 days. The most common complication was postoperative exacerbation of pyelonephritis (13.3% of patients), successfully treated with conservative measures. There were no cases of postoperative bleeding, accompanied by anemia and needed a blood transfusion. Considering high effectiveness and low rate of complications of ultra-mini-PNL, it can be successfully used in treating nephrolithiasis among a wide group of patients.

    Full text: Resistivity of insulators is an important property of materials used within the integrated circuit and packaging industries. The measurement of electrical resistivity of insulator materials in the surface region in this work is interpreted through observations of surface charge decay. A self-field driven and diffusion charge transport theory is used to model the process and resistivity values obtained computationally. Data for the charge decay of surface charged samples are collected by suspending them inside a coaxial cylinder connected to an electrometer. Samples used have been low density polyethylene LDPE sheet, both pristine and surface treated. Some samples have been treated by air plasma at low vacuum pressures for different periods of time; others have been washed in ethyl acetate and then plasma treated before the resistivity measurement. The sets of resistivity measurements form the various treatments are compared below. X-ray photoelectron spectroscopy (XPS) has also been used to investigate and account for the observed variations in surface resistivity

    Children ranging from 3 to 5 years were introduced to two anthropomorphic robots that provided them with information about unfamiliar animals. Children treated the robots as interlocutors. They supplied information to the robots and retained what the robots told them. Children also treated the robots as informants from whom they could seek information. Consistent with studies of children's early sensitivity to an interlocutor's non-verbal signals, children were especially attentive and receptive to whichever robot displayed the greater non-verbal contingency. Such selective information seeking is consistent with recent findings showing that although young children learn from others, they are selective with respect to the informants that they question or endorse.

    Snyder, Douglas K; Doss, Brian D

    2005-11-01

    This article addresses clinical and ethical directions in treating clients coping with infidelity. Developing competence in this domain requires familiarity with empirical research regarding infidelity, individual and cultural differences involving non-monogamy, and assessment and intervention skills related to treating infidelity. Practical directions will entail distinguishing among responsibilities to individual partners versus their relationship and managing related potential conflicts of interest with other involved parties. Confidentiality assumes increased complexity when confronting undisclosed infidelity in couple therapy and when a client engaging in high-risk behaviors for contracting STDs or testing seropositive for HIV has not informed his or her partner(s). Finally, we discuss therapists' need to concretely articulate their values that influence treatment of infidelity.

    Full text: Agricultural wastes such as palm oil residue, rice husk and sugarcane bagasse have been found to occupy the largest fraction in the total biomass generated in Malaysia. These residues are normally lacking of commercial values and have limited alternative uses. Since they are being generated substantially every year, their disposal has caused a serious problem to the society and the environment. Hence, it is essential to discover the potentials of converting these wastes into wealth. One of the major drawbacks which hinder their effective utilization is due to their recalcitrant nature. Thus, pretreatment is necessary in order to disrupt the complex carbohydrate structures in the substrate and improves its digestibility. The present study showed the efficiencies of various mediums namely ionic liquid, acid, alkali and water in pre treating sugarcane bagasse. The performances of these pretreatment mediums were evaluated by the reducing sugar generated after enzymatically hydrolysed the treated substrate. The results obtained were compared with the untreated sugarcane bagasse. In this study, substrate treated by ionic liquid has yielded the highest amount of reducing sugar followed by alkali treated substrate. The performance of untreated bagasse is found to be better than acid and water treated bagasse. These results showed that ionic liquid which has been identified as the green solvent can be an effective medium in pre treating the sugarcane bagasse. This finding has given a new prospect in the production of value added products from agricultural wastes. (author)

    Somatic symptom disorder (SSD) is a challenging condition to treat with chronic pain, a common and disabling symptom. We present a patient who received electroconvulsive therapy (ECT) for SSD with significant improvement in pain and gastrointestinal symptoms. We also present a brief literature review of similar cases treated with ECT. Preliminary evidence suggests that ECT should be considered for treatment of SSD comorbid with major depressive disorder, when standard treatments fail. Further research is needed to clarify whether ECT can be used for SSD without associated depression.

    Full Text Available Clinical success of endodontically treated posterior teeth is determined by the postendodontic restoration. Several options have been proposed to restore endodontically treated teeth. Endocrowns represent a conservative and esthetic restorative alternative to full coverage crowns. The preparation consists of a circular equigingival butt-joint margin and central retention cavity into the entire pulp chamber constructing both the crown and the core as a single unit. The case reports discussed here are moderately damaged endodontically treated molars restored using all ceramic endocrowns fabricated using two different systems, namely, CAD/CAM and pressed ceramic.

    Full Text Available We present the case of a 79-year-old man who showed multiple pulmonary nodules on chest computed tomography (CT after being treated for 6 months with ruxolitinib, an inhibitor of Janus kinase (JAK 1 and 2, to treat primary myelofibrosis. We examined the lesions by bronchoscopy, and the biopsy specimen revealed fungus bodies of Cryptococcus with granulomatous inflammation. As a result, the patient was diagnosed with pulmonary cryptococcosis. The patient was treated with fluconazole (200 mg daily for 2 weeks with concomitant ruxolitinib administration, but the pulmonary lesions progressed. Subsequently, the patient was treated with voriconazole (300 mg daily for 3 weeks, but the lesions worsened further. The administration of ruxolitinib was therefore discontinued, and the dosage of voriconazole was increased to 400 mg daily. Three months later, the pulmonary lesions diminished in size. The present case of pulmonary cryptococcosis occurred in a patient treated with ruxolitinib. Treatment of pulmonary cryptococcosis with concomitant JAK inhibitor administration may result in poor treatment efficacy. It might be better to stop administration of JAK inhibitors, if possible, in patients being treated for pulmonary cryptococcosis.

    Nanotube titanic acid (NTA) has distinct optical and electrical character, and has photocatalysis character. In accordance with these qualities, NTA was treated with acid so as to enhance its surface activity. Surface structures and surface groups of acid-treated NTA were characterized and analyzed by Transmission Electron Microscope (TEM) and Fourier Transform Infrared Spectrometry (FT-IR). The interaction between acid-treated NTA and amino acids was investigated. Analysis results showed that the lengths of acid-treated NTA became obviously shorter. The diameters of nanotube bundles did not change obviously with acid-treating. Meanwhile, the surface of acid-treated NTA was cross-linked with carboxyl or esterfunction. In addition, acid-treated NTA can catch amino acid residues easily, and then form close combination.

    2015-01-01

    Full Text Available Abstract Fly ash, an inorganic alumino silicate has been used as filler in epoxy matrix, but it reduces the mechanical properties due to its poor dispersion and interfacial bonding with the epoxy matrix. To improve its interfacial bonding with epoxy matrix, surface treatment of fly ash was done using surfactant sodium lauryl sulfate and silane coupling agent glycidoxy propyl trimethoxy silane. An attempt is also made to reduce the particle size of fly ash using high pressure pulverizer. To improve fly ash dispersion in epoxy matrix, the epoxy was modified by mixing with amine containing liquid silicone rubber (ACS. The effect of surface treated fly ash with varying filler loadings from 10 to 40% weight on the mechanical, morphological and thermal properties of modified epoxy composites was investigated. The surface treated fly ash was characterized by particle size analyzer and FTIR spectra. Morphological studies of surface treated fly ash filled modified epoxy composites indicate good dispersion of fillers in the modified epoxy matrix and improves its mechanical properties. Impact strength of the surface treated fly ash filled modified epoxy composites show more improvement than unmodified composites.

    Mercury (Hg) contamination of soils and sediments is one of many environmental problems at the Oak Ridge Reservation, Oak Ridge, TN. Mercury-contaminated soil from the Lower East Fork Poplar Creek (LEFPC) at the Oak Ridge Reservation was treated thermally to reduce Hg concentration to a below target level (20 mg kg{sup {minus}1}) as a pilot scale thermal treatment demonstration. As a part of performance evaluation, the soil characteristics and plant growth response of the untreated and treated soil were examined. The soil treated at 350 C retained most of its original soil properties, but the soil treated at 600 C exhibited considerable changes in mineralogical composition and physicochemical characteristics. Growth and physiological response of the three plant species radish (Raphanus sativus L.), fescue (Festuca arundinacea Schreb.), and oat (Avena sativa L.) indicated adverse effects of the thermal treatment. The addition of N fertilizer had beneficial effects in the 350 C treated soil, but had little beneficial effect in the 600 C treated soil. Some changes of soil characteristics induced by thermal treatment cannot be avoided. Soil characteristics and phytotoxicity test results strongly suggest that changes occurring following the 350 C treatment do not limit the use of the treated soil to refill the excavated site for full-scale remediation. The only problem with the 350 C treatment is that small amounts of Hg compounds (<15 mg kg{sup {minus}1}) remain in the soil and a processing cost of $45/Mg.

    Complex relationships commonly exist between owners and their companion animals, particularly around feeding behaviour with an owner's affection or love for their animal most pronounced through the provision of food. It is notable that the pet food market is experiencing strong year-on-year growth in sales of dog and cat treats. Recognising the impact of treat giving in pet nutrition, the objective of the study was to investigate owner attitudes and motivations towards feeding treats (shop bought and other) to their dogs. A researcher-mediated questionnaire consisting of both quantitative and qualitative questions was used to interview dog owners (n=280) at two locations: an out-of-town retail park and a country park in the East Midlands. Owners almost unanimously viewed the word 'treat' within a nutritional context, as opposed to a new toy or other pleasure. The majority (96%) of owners interviewed reported feeding treats to their dog, with 69% feeding shop-bought treats on a daily basis. A wide range of treats was reportedly given by owners and the majority of owners interviewed fed multiple treat types. No association was found between owner age and frequency of shop-bought treats fed (P=0.659) nor between owner age and frequency of food given to the dog from the owner's plate (P=0.083). A wide range of foods which would not be considered balanced for the animal's nutritional requirements was viewed as a treat by some dog owners. A range of positive and negative views around the feeding of treats were expressed by dog owners, with some citing beneficial effects while others were clearly aware of the association between treat feeding and potential weight gain/obesity. Owner views included themes around positive reinforcement and responsibility but also reflected relational aspects of the human-animal bond. The results of the study show that treat giving is commonplace in feeding regimes and that treats are embedded in the feeding behaviour of many dog owners

    The testing of candidate fuel elements at prototypic operating conditions with respect to temperature, power density, hydrogen coolant flow rate, etc., is a crucial component in the development and qualification of nuclear rocket engines based on the Particle Bed Reactor (PBR), NERVA-derivative, and other concepts. Such testing may be performed at existing reactors, or at new facilities. A scoping study has been performed to assess the feasibility of testing PBR based fuel elements at the TREAT reactor. Initial results suggests that full-scale PBR elements could be tested at an average energy deposition of ∼60--80 MW-s/L in the current TREAT reactor. If the TREAT reactor was upgraded to include fuel elements with a higher temperture limit, average energy deposition of ∼100 MW/L may be achievable

    1968-04-09

    A method of well stimulation consists of introducing a fluid medium into the well separate from the treating fluid. A volume is created within the medium of pressure less than that of the medium adjacent to the formation to be treated. This is performed by substantially instantaneously collapsing the created volume, which creates at least one rarefactional wave pulse. This is followed by a compressional wave pulse. The treating fluid is injected into the fluid medium in time sequence with the compressional wave pulse. The rarefactional and compressional pulses are conducted to the formation. (14 claims)

    2015-10-28

    Fe-Si-B metallic glass foils were treated with a linear laser track using a continuous wave Nd-YAG laser and its effect on the overall tensile behavior was investigated. Microstructure and phase evolutions were evaluated using X-ray diffraction, resistivity measurements, and transmission electron microscopy. Crystallization fraction was estimated via the differential scanning calorimetry technique. Metallic glass foils treated with the lower laser fluences (<0.49 J/mm{sup 2}) experienced structural relaxation, whereas higher laser fluences led to crystallization within the laser treated region. The overall tensile behavior was least impacted by structural relaxation, whereas crystallization severely reduced the ultimate tensile strength of the laser treated metallic glass foils.

  4. Pump-and-treat is not the only solution to aquifer remediation

    International Nuclear Information System (INIS)

    Odermatt, J.R.

    1994-01-01

    The Environmental Protection Agency (EPA) recently surveyed remediation technologies used at petroleum-contaminated sites in 22 states. About 96 percent of underground storage tank (UST) corrective action sites used some form of pump-and-treat technology to remediate contaminated groundwater. However, using only pump-and-treat technology is not a cost-effective approach to aquifer remediation. Pump-and-treat may be more appropriate for containing plumes or for use in initial emergency response actions at sites and massive NAPL releases to groundwater. As of 1990, 68 percent of Superfund records of decision selected pump-and-treat as the final remedy for aquifer remediation. However, of 13 sites where the remedial alternative objective was to restore the aquifer to health-based levels, only one pump-and-treat method has succeeded. Except in cases where human health and the environment are threatened, long-term active technologies, such as pump-and-treat, may not be warranted. Groundwater monitoring and possible wellhead treatment may be perceived as time-consuming processes; however, at many sites, this long-term approach may be far less costly and just as effective as other long-term strategies based on exclusive use of pump-and-treat technology

  7. Treat mine water using passive methods

    1993-01-01

    Passive treatment represents an alternative to conventional chemical treatment of coal mine drainage. When successful, passive systems require less investment, less maintenance and usually are less expensive than conventional chemical treatment systems. As a result, during the last seven years, more than 500 passive systems have been constructed in the United States to treat coal mine drainage. Some exist as an alternative to conventional treatment; others serve as an inexpensive pretreatment step than can decrease subsequent chemical requirements. Sulfide minerals present in rock disturbed during mining can oxidize to form an acidic metal-laden solution, commonly known as acid mine drainage (AMD). Alkalinity present in the rock may partially or completely neutralize AMD, but if either acidity or excessive metal contaminants remain, the water must be treated before it can be discharged legally. The principal regulated contaminant metals of coal mine drainage are iron and manganese. Metal mine drainage often contains more toxic metals, such as cadmium, nickel, copper and zinc. Chemical treatment of AMD is estimated to cost America's mining industry more than $1 million a day. Three principal passive technologies are used in the treatment of coal mine drainage: Aerobic wetlands, wetlands constructed with an organic substrate and anoxic limestone drains (ALDS). The selection of the technology or combination of technologies to be used depends on the quality of the water being treated

    Full Text Available We describe an original protocol Treating Depression Downhill (TDD that was designed as a specific therapy for depression. Evolutionary theories of depression served as a basis for its development. We discuss the rationale for using evolutionary theory and describe the structure and integrative nature of TDD. We then present an observation on TDD’s application to group therapy of active duty military personnel. In the described sample, TDD demonstrated effectiveness and specificity for depression, differentiating it from anxiety and personality disorders.

    Puberty suppression using gonadotropin-releasing-hormone analogues (GnRHa) has become increasingly accepted as an intervention during the early stages of puberty (Tanner stage 2-3) in individuals with clear signs of childhood-onset gender dysphoria. However, lowering the age threshold for using medical intervention for children with gender dysphoria is still a matter of contention, and is more controversial than treating the condition in adolescents and adults, as children with gender dysphor...

  11. Adverse drug reaction and toxicity caused by commonly used antimicrobials in canine practice

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available An adverse drug reaction (ADR is a serious concern for practicing veterinarians and other health professionals, and refers to an unintended, undesired and unexpected response to a drug that negatively affects the patient's health. It may be iatrogenic or genetically induced, and may result in death of the affected animal. The ADRs are often complicated and unexpected due to myriad clinical symptoms and multiple mechanisms of drug-host interaction. Toxicity due to commonly used drugs is not uncommon when they are used injudiciously or for a prolonged period. Licosamides, exclusively prescribed against anaerobic pyoderma, often ends with diarrhoea and vomiting in canines. Treatment with Penicillin and β-lactam antibiotics induces onset of pemphigious vulgare, drug allergy or hypersensitivity. Chloroamphenicol and aminoglycosides causes Gray's baby syndrome and ototoxicity in puppies, respectively. Aminoglycosides are very often associated with nephrotoxicity, ototoxicity and neuromuscular blockage. Injudicious use of fluroquinones induces the onset of arthropathy in pups at the weight bearing joints. The most effective therapeutic measure in managing ADR is to treat the causative mediators, followed by supportive and symptomatic treatment. So, in this prospective review, we attempt to bring forth the commonly occurring adverse drug reactions, their classification, underlying mechanism, epidemiology, treatment and management as gleaned from the literature available till date and the different clinical cases observed by the authors.

    Macrophage activating factor (MAF)-based immunotherapy has a wide application for use in treating many diseases via macrophage activation. Sonodynamic therapy (SDT) using low-intensity ultrasound and tumor treating field (TTF) therapy are novel therapeutic modalities. SDT is usually combined with ozone therapy to improve local hypoxia within the tumor environment. We treated a 77-year-old male diagnosed with non-small cell lung cancer ((NSCLC) stage 3B) using second-generation serum GcMAF and oral colostrum MAF-based immunotherapy combined with SDT, TTF and ozone therapies. This case report demonstrates that GcMAF, oral colostrum MAF, SDT, TTF and ozone therapy can be used for NSCLC without adverse effects. This case report suggests a new concept of cancer treatment using local destruction of cancer tissue, in this case conducted with SDT and TTF therapy, to be used in combination with serum GcMAF and colostrum MAF immunotherapy as a systemic treatment.

    Bioengineering strategies have demonstrated enormous potential to treat female infertility as a result of chemotherapy, uterine injuries, fallopian tube occlusion, massive intrauterine adhesions, congenital uterine malformations, and hysterectomy. These strategies can be classified into two broad categories as follows: (i) Transplantation of fresh or cryopreserved organs into the host and (ii) tissue engineering approaches that utilize a combination of cells, growth factors, and biomaterials that leverages the body's inherent ability to regenerate/repair reproductive organs. While whole organ transplant has demonstrated success, the source of the organ and the immunogenic effects of allografts remain challenging. Even though tissue engineering strategies can avoid these issues, their feasibilities of creating whole organ constructs are yet to be demonstrated. In this article we summarize the recent advancements in the applications of bioengineering to treat female infertility.

    Post-intubation tracheal stenosis accounts for the greatest proportion of whole-cause tracheal stenosis. Treatment of post-intubation tracheal stenosis requires a multidisciplinary approach. Surgery or an endoscopic procedure can be used, depending on the type of stenosis. However, the efficacy of cryotherapy in post-intubation tracheal stenosis has not been validated. Here, we report a case of recurring post-intubation tracheal stenosis successfully treated with bronchoscopic cryotherapy that had previously been treated with surgery. In this case, cryotherapy was effective in treating web-like fibrous stenosis, without requiring more surgery. Cryotherapy can be considered as an alternative or primary treatment for post-intubation tracheal stenosis. PMID:27853078

    1987-10-01

    Full Text Available It appears that until bone graft has not achieved 100% success, intraradicular diseases remain controversial and therefore, different treatment plans are suggested for them. Treating intraradicular diseases depend on many factors: maxillary molars are more prone to bone loss and have worse prognosis. To assess prognosis more carefully these factors should be considered: 1 bone loss: its apical depth, local or generalized 2 bone condition: buccal, lingual, mesial and distal aspects 3 tooth mobility: grades 2 and 3 have not good prognosis. Crown root ratio is also important. 4 the angle of divergence of roots: the more the roots are divergent, the better the prognosis would be. 5adjacent teeth health 6tooth position in jaws 7 age and general health of the patients 8 oral hygiene In general, teeth with 2 roots can be treated more effectively than 3 root ones. Maxillary first premolars are exceptions that do not respond to the treatments positively. We should look forward to the future investigations and findings.

  4. Treating leachate by Fenton oxidation

    Full Text Available Leachates are formed from liquids, mainly rainwater, percolating through solid wastes during stabilisation. Their composition is variable and highly toxic; leachate treatment is therefore a complex task. Leachates represent a high risk to health due to the Yucatan Peninsula’s highly permeable soil. The results are presented from applying the Fenton process to treating leachate from the sanitary Merida landfill, Yucatan, Mexico. The Fenton process consists of treating the contaminant load with an H2O2 and FeSO4 combination in acidic conditions. Optimal reaction time, pH value, Fenton reagent dose, post treatment coagulation – flocculation doses and increased biodegradability index were all determined. Optimal oxidation conditions and doses were 202+ minute contact time, 4 pH, 600 mg/L H2O2 concentration and 1,000 mg/L Fe. Average organic matter removal rate, measured as CODS and TOC, were 78% and 87% respectively. The biodegradability index increased from 0.07 to 0.11 during the Fenton process and up to 0.13 when the Fenton process was followed by coagulation-flocculation.

    The purpose of the present study was to investigate the effect of thermal-treating on the release of ibuprofen from the granules prepared using aqueous dispersions of Eudragit. To accomplish this goal, different formulations were prepared using wet granulation method containing two different types of Eudragit aqueous dispersions, RS30D, RL30D and Avicel as filler. Tablets were prepared using direct compression method. The prepared tablets were thermally treated at 50 and 70 degrees C for 24 h. The drug release from tablets was assessed before and after thermal-treating. The results of release study showed that, thermally-treating the tablets at the temperatures higher than glass transition temperature (Tg) of the polymer can decrease the drug release from matrices. For mechanistic evaluation of the effect of thermal-treating, powder X-ray diffraction (XPD), scanning electron microscopy (SEM), differential scanning calorimeter (DSC), Fourier transform infrared (FT-IR) and helium pycnometer have been employed. The SEM graphs showed that the tablets have smoother surface with less porosity after thermal-treating. FT-IR spectra showed no change in the spectrum of thermally-treated tablet compared to control. In DSC graphs, no crystalline change was seen in the heat-treated samples of ibuprofen tablets, but decreased and widened peak size were related to the probable formation of solid solution of ibuprofen in Eudragit matrix. The results of helium pycnometer showed a significant decrease in the total porosity of some heat-treated samples. This study revealed the importance of thermal treating on the drug release from sustained release tablets containing Eudragit polymer.

    Objective: The most commonly reported side effects of salsalate are gastrointestinal events, and few reports are available on its cutaneous side effects. We therefore assessed cutaneous side effects among diabetic/pre-diabetic patients treated with salsalate. Methodology: In a randomized placebo-controlled trial, we evaluated cutaneous side effects in 52 diabetic and 124 pre-diabetic patients, 90 of whom received 3 g/day salsalate and 86 of whom receive a placebo for four weeks. The evaluation was carried out every week using a checklist completed by a single general practitioner. Results: The difference between the salsalate- and placebo-treated groups in overall prevalence of cutaneous reactions was not significant (26.7% versus 17.4%; P < 0.05). Side effects included urticaria (nine (10.1%) salsalate-treated versus six (6.9%) placebo-treated), rashes (five (5.5%) salsalate-treated versus three (3.4%) placebo-treated), pruritus (six (6.7%) salsalate-treated versus three (3.4%) placebo-treated), and edema (two (2.2%) salsalate-treated versus one (1.2%) placebo-treated); in addition, one (1.1%) case of erythema nodosum and one (1.1%) of vasculitis were observed in the salsalate-treated group. In the salsalate group, therapy was discontinued by the physician for three (3.3%) patients because of acute and severe vasculitis, erythema nodosum and urticaria and two (2.2%) patients stopped the treatment themselves because of mild urticaria compared with two patients who stopped using the placebo. Conclusions: Salsalate can cause several and, in some cases, severe cutaneous side effects in patients with diabetes/pre-diabetes. Because these cutaneous eruptions can raise various concerns, including patient non-compliance, greater attention should be paid to dermatological problems in patients under salsalate treatment.

    Analyses were performed to evaluate the performance of the low enriched uranium (LEU) conceptual design fuel for the conversion of the Transient Reactor Test Facility (TREAT) from its current highly enriched uranium (HEU) fuel. TREAT is an experimental nuclear reactor designed to produce high neutron flux transients for the testing of reactor fuels and other materials. TREAT is currently in non-operational standby, but is being restarted under the U.S. Department of Energy’s Resumption of Transient Testing Program. The conversion of TREAT is being pursued in keeping with the mission of the Department of Energy National Nuclear Security Administration’s Material Management and Minimization (M3) Reactor Conversion Program. The focus of this study was to demonstrate that the converted LEU core is capable of maintaining the performance of the existing HEU core, while continuing to operate safely. Neutronic and thermal hydraulic simulations have been performed to evaluate the performance of the LEU conceptual-design core under both steady-state and transient conditions, for both normal operation and reactivity insertion accident scenarios. In addition, ancillary safety analyses which were performed for previous LEU design concepts have been reviewed and updated as-needed, in order to evaluate if the converted LEU core will function safely with all existing facility systems. Simulations were also performed to evaluate the detailed behavior of the UO2-graphite fuel, to support future fuel manufacturing decisions regarding particle size specifications. The results of these analyses will be used in conjunction with work being performed at Idaho National Laboratory and Los Alamos National Laboratory, in order to develop the Conceptual Design Report project deliverable.

  9. Sexual Issues in Treating Trauma Survivors.

    Science.gov (United States)

    Zoldbrod, Aline P

    The effect of interpersonal trauma on sexuality can be profound. The field of sexual trauma is complex empirically and clinically, with contradictory theories and conflicting data. Research definitions and treatment protocols for child sexual abuse are very imprecise. There are no firm, empirically proven guidelines for treating men and women who have been sexually abused as children or adolescents. Overt sexual abuse (OSA) in children and adolescents is defined here as molestation, rape, or incest. Research has shown that OSA may, but does not necessarily, lead to sexual dysfunction in adulthood. The effects of OSA are worsened by concurrent types of family of origin abuse, such as emotional abuse or physical abuse. One factor that seems related to the varying impact of OSA on adult sexuality is the patients' family of origin experience with nonsexual Milestones of Sexual Development. Without positive experiences with touch, trust and empathy, the ability to relax and be soothed, and power, the effects of OSA are potentiated and complicated. Sexuality is embodied, so experiences with touch are particularly important when working with OSA. A three-color Body Map technique which assesses stored associations to touch is provided. The concept of developmental sexual trauma (DST) is introduced as a way to label traumagenic family events which potentiate OSA or negatively effect sex but which are not explicitly sexual in origin. Strategies to assess and treat OSA are reviewed. Body Maps are recommended to assess and treat sexual trauma.

    Full Text Available Evaluation of protective effect of fennel on mouse ovary against the destructive effects of cyclophosphamide (CP was the aim of this study. Adult female NMARI mice were randomly divided into six groups (n = 8: (A negative control, (B CP200 mg/kg, (C fennel 400 mg/kg/day, (E, F, and D that received fennel 200, 400 and 100 mg/kg/day respectively + CP200 mg/kg. Their ovary weight, volume, and diameter (WVD were measured. Five micron sections were stained using the H&E method. The serum levels of oestrogen and progesterone were measured using ELISA kit. The results showed that WVD significantly reduced in the CP-treated groups in comparison with the A and C, but WVD increased after treatment of the mice with fennel extract, in comparison with B group. A significant decrease of serum in terms of oestrogen and progesterone levels among CP-treated groups in comparison with the A group was observed. In the CP-treated groups a reduction in the number of different ovarian follicles in comparison with the A and C groups was observed. However, in the treated animals with fennel extract, these parameters significantly increased in comparison with the B group. Finally, it is concluded that fennel can protect ovary from cyclophosphamide side effects. Keywords: Cyclophosphamide, Fennel, Mice, Ovary

    1987-12-15

    The economic benefits of treating lactating cows for Streptococcus agalactiae mastitis were studied at a large (689 milking cows) central California dairy. Postcure milk production of case cows (infected, treated, and cured) was compared with production of paired control cows (uninfected) and was matched for yield, days in milk, days in gestation, and parity. A simulation was used to plot expected lactation curves for mastitic cows (infected, not treated) with characteristics similar to those of each control cow, and these curves were compared with actual case-cow lactation curves. The difference in actual and expected production was used to calculate net economic benefits of treatment. Comparison of expected with actual production indicated a net benefit from treatment of $396/cow for cows treated in early lactation and $237 for cows treated in midlactation, but a net loss of $55 for cows treated in late lactation. Lactation number did not have a significant impact on economic benefits of treatment. In contrast to other studies indicating no economic benefit from treating mastitis during lactation, this study's positive results may have been attributable to the high cure rate (98%) and the subclinical form of mastitis being treated. Streptococcus agalactiae mastitis treatment during early and midlactation would appear to be an economically justifiable option for dairy managers.

  16. Meta-analysis, Simpson's paradox, and the number needed to treat

    Directory of Open Access Journals (Sweden)

    Deeks Jonathan J

    2002-01-01

    Full Text Available Abstract Background There is debate concerning methods for calculating numbers needed to treat (NNT from results of systematic reviews. Methods We investigate the susceptibility to bias for alternative methods for calculating NNTs through illustrative examples and mathematical theory. Results Two competing methods have been recommended: one method involves calculating the NNT from meta-analytical estimates, the other by treating the data as if it all arose from a single trial. The 'treat-as-one-trial' method was found to be susceptible to bias when there were imbalances between groups within one or more trials in the meta-analysis (Simpson's paradox. Calculation of NNTs from meta-analytical estimates is not prone to the same bias. The method of calculating the NNT from a meta-analysis depends on the treatment effect used. When relative measures of treatment effect are used the estimates of NNTs can be tailored to the level of baseline risk. Conclusions The treat-as-one-trial method of calculating numbers needed to treat should not be used as it is prone to bias. Analysts should always report the method they use to compute estimates to enable readers to judge whether it is appropriate.

    Composite finger-jointed spruce and oak wood panels have been thermally treated under standard pressure and oxygen content conditions at two different temperatures, 180 °C and respectively 200 °C for short time periods (3 and 5 h). Due to the thermally-aided chemical restructuration of the wood components, a decrease in water uptake and volumetric swelling values with up to 45% for spruce and 35% for oak have been registered, comparing to the reference samples. In relation to water resistance, a 15% increase of the dispersive component of the surface energy has been registered for the thermal-treated spruce panels, which impedes water spreading on the surface. The thermal-treated wood presents superior resistance to accelerated UV exposure and subsequently, with up to 10% higher Brinell hardness values than reference wood. The proposed thermal treatment improves the durability of the finger-jointed wood through a more economically and environmental friendly method than traditional impregnation, with minimal degradative impact on the structural components of wood.

    Avascular necrosis (AVN) of the bones of the wrist most commonly involves the lunate followed by the proximal pole of the scaphoid and the capitate. Trapezium avascular necrosis is extremely rare with only two cases reported in the literature, both of which were treated surgically. In this article, we report a unique case of trapezium avascular necrosis treated conservatively. A 38-year-old man complaining of a 4-month history of mild pain on the base of his right thumb. MRI scan was performed. The clinical presentation and the imaging findings indicated avascular osteonecrosis of the trapezium. The patient was treated with immobilization of the wrist joint for a period of six weeks. Three months later, the patient was free of symptoms and the MRI scan revealed a normal trapezium. AVN of trapezium is extremely rare. Our case shows that immobilization of an early stage avascular necrosis of the trapezium might be a treatment option.

    Objective: To assess the clinical effects of uterine arterial embolization on uterine leiomyoma. Methods: The authors treated 21 patients with uterine leiomyoma by Seldinger's uterine arterial embolization. The 4.0 F Cobra catheter was laced into the double uterine arteries with Polyvinyl Alcohol Foam (PVA) particles as the embolization. At 3 and 6 months postoperatively, the authors investigated the effects of the embolization. Results: After uterine arterial embolization, the volume of uterine leiomyoma decreased and menorrhagia was under controlled. The symptoms of anemia and oppression were relieved. The physiologic functions of ovary and uterus were preserved completely. Conclusions: Uterine arterial embolization is an effective and less invasive way to treat uterine leiomyoma

    Full Text Available Restoration of endodontically treated teeth is important for the success of endodontic treatment. In full coverage restorations, maximum amount of tooth structure is compromised, so as to conserve the amount of tooth structure partial coverage restorations, can be preferred. This case report is on fabrication of a conservative tooth colored restoration for an endodontically treated posterior tooth. A 22-year-old male patient presented with pain in the mandibular left first molar. After endodontic treatment, composite material was used as postendodontic restoration. The tooth was then prepared to receive a ceramic onlay and bonded with self-adhesive universal resin cement. Ceramic onlay restoration was periodically examined up to 2 years.

    Full Text Available ABSTRACT Introduction: In addition to well-established physical characteristics, Turner syndrome patients have distinct craniofacial morphology. Since short stature is the most typical characteristic, Turner syndrome patients are commonly treated with growth hormone in order to increase final height. At the same time, growth hormone treatment was found to influence craniofacial growth and morphology in various groups of treated patients. Whereas craniofacial characteristics of Turner syndrome patients are well documented, comparatively little is known of craniofacial morphology of those who are treated with growth hormone. Aim: The aim of this study was to investigate craniofacial morphology in Turner syndrome patients treated with growth hormone in comparison to healthy females. Materials and methods: The cephalometric evaluation was conducted on twenty lateral cephalograms of Turner syndrome patients (13.53 ± 4.04 years treated with growth hormone for at least one year (4.94 ± 1.92 years in average. As a control group, forty lateral cephalograms of healthy female controls, who matched Turner syndrome patients by chronological (11.80 ± 2.37 years and skeletal age, were used. Eleven angular, seven linear measurements and six dimensional ratios were measured to describe craniofacial morphology. Results: The results obtained for angular measurements, in cephalometric analyses for Turner syndrome patients treated with growth hormone, revealed bimaxillary retrognathism. The linear measurements indicated longer mandibular ramus, anterior cranial base and both anterior and posterior facial heights. However, posterior cranial base and maxilla were in proportion to the anterior cranial base, when comparing dimensional ratios. Anterior cranial base, maxilla and mandibular ramus were larger in proportion to mandibular body; as well as posterior facial height was when compared to anterior facial height.

    Fidaxomicin is sporicidal and may be associated with a reduced time to resolution of diarrhoea when used to treat patients with Clostridium difficile infection (CDI). This study investigated whether fidaxomicin for treatment of all patients with CDI reduced C. difficile environmental contamination. Surfaces in the rooms of 66 hospitalized patients treated with metronidazole and/or vancomycin and 68 hospitalized patients treated with fidaxomicin were sampled. Patients treated with fidaxomicin were less likely to contaminate their environment (25/68, 36.8%) than patients treated with metronidazole and/or vancomycin (38/66 57.6%) (P = 0.02). Treatment with fidaxomicin was associated with reduced environmental contamination with C. difficile. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    The presence of injection related anxiety and phobia may influence compliance, glycaemic control and quality of life in patients with insulin-treated diabetes. Unselected consecutive, insulin-treated patients attending a diabetes clinic for follow-up, completed a standardised questionnaire providing an injection anxiety score (IAS) and general anxiety score (GAS). A total of 115 insulin-treated (80 Type 1 and 35 Type 2) diabetic patients completed the questionnaire. Injections had been avoided secondary to anxiety in 14% of cases and 42% expressed concern at having to inject more frequently. An IAS > or = 3 was seen in 28% of patients and of these, 66% injected insulin one to two times/day, 45% had avoided injections, and 70% would be bothered by more frequent injections. A significant correlation between IAS and GAS was seen (Kendall's tau-a 0.30, 95% CI 0.19-0.41, P < 0.001). GAS was significantly associated with both previous injection avoidance and expressed concern at increased injection frequency. No significant correlation was seen with HbA1c and injection or general anxiety scores. Symptoms relating to insulin injection anxiety and phobia have a high prevalence in an unselected group of diabetic patients requiring insulin injections and are associated with higher levels of general anxiety.

    The purpose of this study is to examine Electronic Health Record (EHR) adoption among Florida doctors who treat the elderly. This analysis contributes to the EHR adoption literature by determining if doctors who disproportionately treat the elderly differ from their counterparts with respect to the utilization of an important quality-enhancing health information technology application. This study is based on a primary survey of a large, statewide sample of doctors practising in outpatient settings in Florida. Logistic regression analysis was used to determine whether doctors who treat a high volume of elderly (HVE) patients were different with respect to EHR adoption. Our analyses included responses from 1724 doctors. In multivariate analyses controlling for doctor age, training, computer sophistication, practice size and practice setting, HVE doctors were significantly less likely to adopt EHR. Specifically, compared with their counterparts, HVE doctors were observed to be 26.7% less likely to be utilizing an EHR system (OR=0.733, 95% CI 0.547-0.982). We also found that doctor age is negatively related to EHR adoption, and practice size and doctor computer savvy-ness is positively associated. Despite the fact that EHR adoption has improved in recent years, doctors in Florida who serve the elderly are less likely to adopt EHRs. As long as HVE doctors are adopting EHR systems at slower rates, the elderly patients treated by these doctors will be at a disadvantage with respect to potential benefits offered by this technology. © 2010 Blackwell Publishing Ltd.

    1989-01-01

    Recent studies undertaken in southern Africa and elsewhere indicate that many short or single dose treatments are available to treat chancroid. Erythromycin 500 mg three times a day for five days, ciprofloxacin 500 mg, sulphamethopyrazine 800 mg and trimethoprim 1000 mg or sulphametrole 3200 mg and trimethoprim 640 mg as single oral doses, or ceftriaxone 250 mg as a single intramuscular injection are all effective in treating the disease. The widespread use of these regimens largely depends on the accuracy of diagnosis, susceptibilities of local Haemophilus ducreyi isolates to antimicrobials, and financial considerations.

  16. Decreased stability of DNA in cells treated with alkylating agents

    Energy Technology Data Exchange (ETDEWEB)

    1990-12-01

    A modified highly sensitive procedure for the evaluation of DNA damage in individual cells treated with alkylating agents is reported. The new methodology is based on the amplification of single-strandedness in alkylated DNA by heating in the presence of Mg{sup 2+}. Human ovarian carcinoma cells A2780 were treated with nitrogen mustard (HN2), fixed in methanol, and stained with monoclonal antibody (MOAB) F7-26 generated against HN2-treated DNA. Binding of MOAB was measured by flow cytometry with indirect immunofluorescence. Intensive binding of MOAB to control and drug-treated cells was observed after heating in Tris buffer supplemented with MgCl{sub 2}. Thus, the presence of phosphates and MgCl{sub 2} during heating was necessary for the detection of HN2-induced changes in DNA stability. Fluorescence of HN2-treated cells decreased to background levels after treatment with single-strand-specific S{sub 1} nuclease. MOAB F7-26 interacted with single-stranded regions in DNA and did not bind to dsDNA or other cellular antigens. It is suggested that alkylation of guanines decreased the stability of the DNA molecule and increased the access of MOAB F7-26 to deoxycytidines on the opposite DNA strand.

    1994-01-01

    According to the Florida Department of Environ- mental Protection, 5,100 wastewater treatment systems were in operation during 1990. Of this total, 72 percent were domestic wastewater facilities and 28 percent were industrial waste- water facilities. The number of wastewater systems inventoried for 1990 was 1,062 (systems that treated and discharged more than 0.01 Mgal/d or had a plant capacity of greater than 0.04 Mgal/d. Based on this inventory, the estimated discharge of treated wastewater in Florida during 1990 totaled 1,638 million gallons per day. Approxi- mately 65 percent of this water was discharged to surface water during 1990 and the remaining 35 percent was discharged to ground water. Discharge to surface water includes effluent outfalls into the Atlantic Ocean (32 percent), while the re- maining (68 percent) is discharged into the Gulf of Mexico, bays, rivers, wetlands, and other surface water bodies throughout Florida. Discharge to ground-water includes treated effluent outfalls to land application systems (reuse systems and spray fields), drain fields, percolation ponds (51 percent), and to injection wells (49 percent). An estimated 322 million gallons per day of the treated domestic and industrial wastewater was reused during 1990. Discharge of treated domestic wastewater from the 994 systems inventoried in Florida during 1990 totaled 1,353 million gallons per day and served an estimated 8.58 million people (66 percent of the population of Florida in 1990). The remaining 34 percent of the popu- lation (4.36 million) are served by the 2,700 smaller domestic wastewater systems or have individual septic tanks. In 1990, there were 1.56 million septic tanks in Florida. Discharge of industrial wastewater was inventoried for 68 systems in 1990 and totaled 285 million gallons per day. Discharge of domestic wastewater in- creased more than 20 percent and industrial wastewater discharge increased 5 percent from 1985 to 1990. (USGS)

    2016-01-01

    Objective The reasons that doctors may refuse or be reluctant to treat have not been widely explored in the medical literature. To understand the ethical implications of reluctance to treat there is a need to recognise the constraints of doctors working in complex systems and to consider how these constraints may influence reluctance. The aim of this paper is to illustrate these constraints using the case of compensable injury in the Australian context. Design Between September and December 2012, a qualitative investigation involving face-to-face semistructured interviews examined the knowledge, attitudes and practices of general practitioners (GPs) facilitating return to work in people with compensable injuries. Setting Compensable injury management in general practice in Melbourne, Australia. Participants 25 GPs who were treating, or had treated a patient with compensable injury. Results The practice of clinicians refusing treatment was described by all participants. While most GPs reported refusal to treat among their colleagues in primary and specialist care, many participants also described their own reluctance to treat people with compensable injuries. Reasons offered included time and financial burdens, in addition to the clinical complexities involved in compensable injury management. Conclusions In the case of compensable injury management, reluctance and refusal to treat is likely to have a domino effect by increasing the time and financial burden of clinically complex patients on the remaining clinicians. This may present a significant challenge to an effective, sustainable compensation system. Urgent research is needed to understand the extent and implications of reluctance and refusal to treat and to identify strategies to engage clinicians in treating people with compensable injuries.

    In order to resolve some key LMFBR safety issues, ANL personnel are modifying the TREAT reactor to handle much larger experiments. As a result of these modifications, the upgraded Treat reactor will not always operate in a self-limited mode. During certain experiments in the upgraded TREAT reactor, it is possible that the fuel could be damaged by overheating if, once the computer systems fail, the reactor scram system (RSS) fails on demand. To help ensure that the upgraded TREAT reactor is shut down when required, ANL personnel have designed a triply redundant RSS for the facility. The RSS is designed to meet three reliability goals: (1) a loss of capability failure probability of 10 -9 /demand (independent failures only); (2) an inadvertent shutdown probability of 10 -3 /experiment; and (3) protection agaist any known potential common cause failures. According to ANL's reliability analysis of the RSS, this system substantially meets these goals

    2014-08-01

    Full Text Available Ever increasing demands for fresh water resources have brought the reuse of treated wastewater into agendas. Wastewater has year-long potential to be used as an irrigation water source. Therefore, treated wastewater is used as irrigation water over agricultural lands and urban landscapes, as process water in industrial applications, as back-up water in environmental applications in water resources and wetlands of dry regions. The present study was conducted to investigate the possible use of domestic wastewater treated through pilot-scale constructed wetland of Adana-Karaisalı with dominant Mediterranean climate in irrigation of marigold (Tagetes erecta, commonly used over urban landscapes. Experiments were carried out between the dates May-November 2008 for 7 months with fresh water and treated wastewater. Plant growth parameters (plant height, plant diameter, number of branches and flowering parameters (number of flowers, flower diameter, flower pedicle thickness were monitored in monthly basis. Results revealed positive impacts of treated wastewater irrigations on plant growth during the initial 5 months between May-September but negative impacts in October and November. Similarly, treated wastewater irrigations had positive impacts on flowering parameters during the initial 3 months but had negative impacts during the subsequent 4 months. Such a case indicated shortened visual efficiencies of marigold. Therefore, treated wastewater can be used as an alternative water resource in irrigation of annual flowers, but better results can be attained by mixing treated wastewater with fresh water at certain ratios.

    In this Special Session 4 remediation projects are presented, that were run in different environments and under different constraints. The projects / sites showed the following characteristics: Amponville (F) This project represents a successful clean up of an uncontrolled dump by drums containing Chlorophenol-wastes from an old agrochemical production site. Contaminated sandy soil had to be excavated and treated in a Thermal Desorption unit on site. An interactive CD-ROM data medium was created for documentation. Niederglatt (CH) A old industrial area contaminated by organics (hydrocarbons, polyaromatics) as well as by chromium Cr(VI) was remediated by soil-excavation. The soil had to be analysed, separated and treated accordingly. Chromium-contaminated material had to be treated physically and chemically. The soil affected by organic pollutants had to be washed off-site. Special attention was given to the water flowing off the site, groundwater control and to dust deposit measures in the near environment. Dielsdorf (CH) This site contained wastes from former Lindane-production, containing HCH, Dinitro-o-Cresol and metals like As, Cu and Pb. The contaminated soil and the wastes had to be excavated, analysed, partly backfilled and the rest treated in different ways. Residual pollutants concentration was calculated following a risk-analysis/mobility-calculation and agreed upon with the authorities before starting the remediation work. Schweizerhalle (CH) A huge fire left an area of contaminated soil that was affected by argo-chemicals and their incineration-products. The most harmful pollutants were mercury and phosphoric esters. After coverage by a tent and lowering of the groundwater level the gravel and the sandy soil was excavated and treated in an on-site large-scale Soil Washing and Treating installation by using surfactants and other reagents to separate the pollutants. Most of the soil could be backfilled on-site. Less than 5% of the soil volume containing

    Full Text Available Lead, a ubiquitous metal, is one of the most abundant elements present on earth. Its easy availability and cost effectiveness made it an extremely popular component in the industrial revolution. However, its hazardous health effects were not considered at the time. Over the last few decades, with the adverse effects of lead coming to the forefront, nations across the world have started to recognize and treat lead toxicity. The most reliable and used method until now has been chelation therapy. Recent research has suggested the use of natural products and sources to treat lead poisoning with minimal or no side effects. This review has tried to summarize a few of the natural products/sources being investigated by various groups.

    2010-03-01

    Lung cancer in pregnancy is a rare situation; however, it is increasingly reported in the past two decades. The association might be more encountered in the coming years due to the rising trends of cigarette smoking among young women and tendency to delay pregnancy to later in life. We performed a literature search without any date or language restriction and identified 44 cases diagnosed and/or treated for lung cancer during the course of pregnancy. Patients had poor post-partum outcome with less than one-forth alive at 1 year following delivery. There was a high incidence of metastases to the products of conception reaching 26%. Eight patients were treated with systemic therapies during the course of gestation with normal fetal outcome and no evidence of fetal or placental metastases. Counseling of these patients is very important. Apart from the clinical conflict they pose, some ethical aspects should be taken in consideration. The poor maternal prognosis should be discussed and the patient's autonomy should be respected to decide whether she wants to keep the pregnancy or not.

    2017-03-01

    Advanced modeling techniques and current computational capacity make full core TREAT simulations possible, with the goal of such simulations to understand the pre-test core and minimize the number of required calibrations. But, in order to simulate TREAT with a high degree of precision the reactor materials and geometry must also be modeled with a high degree of precision. This paper examines how uncertainty in the reported values of boron and graphite have an effect on simulations of TREAT.

    γ-radiation treatment of radiation sterilized polycarbonate biomaterials has been carried out to ensure efficient disposal by incineration. Low molecular weight polycarbonate sterilized with 2.5 Mrad dose of γ-radiation was further treated with different doses of γ-radiation. The radiation-treated samples were subjected to thermogravimetry. The sterilized sample and the 7.5 Mrad-treated sample showed similar properties. These samples do not leave any residue during thermal decomposition. (author). 5 refs., 3 tables

  12. Treating hydrocarbon oils

    Scott, R; MacIvor, W

    1869-09-01

    The treatment of hydrocarbon oils, such as coal or shale oils, paraffin oils, and petroleum, either in the crude or more or less refined state has the object of reducing the specific gravity and otherwise improving the qualities of such oils. The oil to be treated is put into any ordinary still and distilled. The vapor escaping during the distillation is passed through one or more heating vessels or chambers and exposed to the heat necessary to produce the change. The heating vessels or chambers may be made of metal, clay, or any other material adapted to endure heat, and they may be made of any desired form, or they may be constituted of a coil of metal pipes or a series of tubes such as are used for heating air for blast furnaces.

  13. Review of the TREAT Conversion Conceptual Design and Fuel Qualification Plan

    2017-12-29

    The U.S. Department of Energy (DOE) is preparing to re establish the capability to conduct transient testing of nuclear fuels at the Idaho National Laboratory (INL) Transient Reactor Test (TREAT) facility. The original TREAT core went critical in February 1959 and operated for more than 6,000 reactor startups before plant operations were suspended in 1994. DOE is now planning to restart the reactor using the plant's original high-enriched uranium (HEU) fuel. At the same time, the National Nuclear Security Administration (NNSA) Office of Material Management and Minimization Reactor Conversion Program is supporting analyses and fuel fabrication studies that will allow for reactor conversion to low-enriched uranium (LEU) fuel (i.e., fuel with less than 20% by weight 235U content) after plant restart. The TREAT Conversion Program's objectives are to perform the design work necessary to generate an LEU replacement core, to restore the capability to fabricate TREAT fuel element assemblies, and to implement the physical and operational changes required to convert the TREAT facility to use LEU fuel.

    Metallic taste is a taste alteration frequently reported by cancer patients treated with chemotherapy. Attention to this side effect of chemotherapy is limited. This review addresses the definition, assessment methods, prevalence, duration, etiology, and management strategies of metallic taste in chemotherapy treated cancer patients. Literature search for metallic taste and chemotherapy was performed in PubMed up to September 2014, resulting in 184 articles of which 13 articles fulfilled the inclusion criteria: English publications addressing metallic taste in cancer patients treated with FDA-approved chemotherapy. An additional search in Google Scholar, in related articles of both search engines, and subsequent in the reference lists, resulted in 13 additional articles included in this review. Cancer patient forums were visited to explore management strategies. Prevalence of metallic taste ranged from 9.7% to 78% among patients with various cancers, chemotherapy treatments, and treatment phases. No studies have been performed to investigate the influence of metallic taste on dietary intake, body weight, and quality of life. Several management strategies can be recommended for cancer patients: using plastic utensils, eating cold or frozen foods, adding strong herbs, spices, sweetener or acid to foods, eating sweet and sour foods, using 'miracle fruit' supplements, and rinsing with chelating agents. Although metallic taste is a frequent side effect of chemotherapy and a much discussed topic on cancer patient forums, literature regarding metallic taste among chemotherapy treated cancer patients is scarce. More awareness for this side effect can improve the support for these patients. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Background and purpose: To evaluate local control and survival outcomes in adults with Ewing sarcoma (ES) treated with radiotherapy (RT). Material and methods: Retrospective review of all 109 patients age ⩾18 treated for ES with RT to the primary site at Memorial Sloan Kettering Cancer Center between 1990 and 2011. RT was used as the definitive local control modality in 44% of patients, preoperatively for 6%, and postoperatively for 50%. Results: Median age at diagnosis was 27 years (range, 18–67). The 5-year local failure (LF) was 18%. Differences in LF were not identified when evaluated by modality of local control (RT versus combined surgery and RT), RT dose, fractionation, and RT technique. However, margin status at time of resection significantly predicted LF. The 5-year event-free survival and overall survival rates were 44% and 66% for patients with localized disease, compared with 16% and 26% for metastatic disease (p = 0.0005 and 0.0002). Tumor size, histopathologic response to chemotherapy, and treatment on or according to a protocol were also significantly associated with survival. Conclusions: This series of adults treated with modern chemotherapy and RT had prognostic factors and outcomes similar to adolescents with ES. All adults with ES should be treated with an aggressive, multidisciplinary approach

    Sex steroid treatment to reduce final height of tall boys has been available since the 1950s. In women, it has been shown to interfere with fertility. In men, no such data are available. We therefore evaluated fertility and gonadal function in tall men who did or did not receive high-dose androgen treatment in adolescence. We conducted a retrospective cohort study of 116 tall men, of whom 60 had been treated. Reproductive and gonadal function was assessed by standardized interview, semen analysis, endocrine parameters, ultrasound imaging, and fatherhood. Mean age at treatment commencement was 14.2 yr, and mean follow-up was 21.2 yr. Sixty-six men (36 treated and 30 untreated) had attempted to achieve fatherhood. The probability of conceiving their first pregnancy within 1 yr was similar in treated and untreated men (26 vs. 24; Breslow P=0.8). Eleven treated and 13 untreated men presented with a left-sided varicocele (P=0.5). Testicular volume, sperm quality, and serum LH, FSH, and inhibin B levels were comparable between treated and untreated men. However, treated men had significantly reduced serum T levels, adjusted for known confounders [mean (sd) 13.3 (1.8) vs. 15.2 (1.9) nmol/liter; P=0.005). In addition, testicular volume and serum inhibin B and FSH levels in treated men were significantly correlated with age at treatment commencement. At a mean follow-up of 21 yr after high-dose androgen treatment, we conclude that fatherhood and semen quality in tall treated men are not affected. Serum testosterone levels, however, are reduced in androgen-treated men. Future research is required to determine whether declining testosterone levels may become clinically relevant for these men as they age.

  17. Is clinician refusal to treat an emerging problem in injury compensation systems?

    The reasons that doctors may refuse or be reluctant to treat have not been widely explored in the medical literature. To understand the ethical implications of reluctance to treat there is a need to recognise the constraints of doctors working in complex systems and to consider how these constraints may influence reluctance. The aim of this paper is to illustrate these constraints using the case of compensable injury in the Australian context. Between September and December 2012, a qualitative investigation involving face-to-face semistructured interviews examined the knowledge, attitudes and practices of general practitioners (GPs) facilitating return to work in people with compensable injuries. Compensable injury management in general practice in Melbourne, Australia. 25 GPs who were treating, or had treated a patient with compensable injury. The practice of clinicians refusing treatment was described by all participants. While most GPs reported refusal to treat among their colleagues in primary and specialist care, many participants also described their own reluctance to treat people with compensable injuries. Reasons offered included time and financial burdens, in addition to the clinical complexities involved in compensable injury management. In the case of compensable injury management, reluctance and refusal to treat is likely to have a domino effect by increasing the time and financial burden of clinically complex patients on the remaining clinicians. This may present a significant challenge to an effective, sustainable compensation system. Urgent research is needed to understand the extent and implications of reluctance and refusal to treat and to identify strategies to engage clinicians in treating people with compensable injuries.

    The TREAT reactor was built as a transient irradiation test reactor. By taking advantage of built-in system features, it was possible to add a neutron-radiography facility. This facility has been used over the years to radiograph a wide variety and large number of preirradiated fuel pins in many different configurations. Eight different specimen handling casks weighing up to 54.4 t (60 T) can be accommodated. Thermal, epithermal, and track-etch radiographs have been taken. Neutron-radiography service can be provided for specimens from other reactor facilities, and the capacity for storing preirradiated specimens also exists

    Several clinical treatments have been proposed to manage symptoms of fibromyalgia. Low-level laser therapy (LLLT) may be a useful tool to treat this dysfunction. The aim of this study was to evaluate the effects of LLLT in patients with fibromyalgia. A placebo-controlled, randomized clinical trial was carried out with 20 patients divided randomly into either an LLLT group (n = 10) or a placebo group (n = 10). The LLLT group was treated with a GaAlAs laser (670 nm, 4 J/cm(2) on 18 tender points) three times a week over 4 weeks. Before and after treatment, patients were evaluated with the Fibromyalgia Impact Questionnaire (FIQ), McGill Pain Questionnaire, and visual analog scale (VAS). Data from the FIQ and McGill questionnaire for the treated and control groups were analyzed by paired t tests, and Wilcoxon tests were used to analyze data from the VAS. After LLLT or sham treatment, the number of tender points was significantly reduced in both groups (LLLT, p fibromyalgia symptoms showed significant improvements after LLLT compared to placebo (FIQ, p = 0.0003; McGill, p = 0.0078; and VAS, p = 0.0020). LLLT provided relief from fibromyalgia symptoms in patients and should be further investigated as a therapeutic tool for management in fibromyalgia.

  3. Municipal Treated Wastewater Irrigation: Microbiological Risk Evaluation

    Directory of Open Access Journals (Sweden)

    Antonio Lonigro

    2008-06-01

    Full Text Available Municipal wastewater for irrigation, though treated, can contain substances and pathogens toxic for humans and animals. Pathogens, although not harmful from an agronomical aspect, undoubtedly represent a major concern with regards to sanitary and hygienic profile. In fact, vegetable crops irrigated with treated wastewater exalt the risk of infection since these products can also be eaten raw, as well as transformed or cooked. Practically, the evaluation of the microbiological risk is important to verify if the microbial limits imposed by law for treated municipal wastewater for irrigation, are valid, thus justifying the treatments costs, or if they are too low and, therefore, they don’ t justify them. Different probabilistic models have been studied to assess the microbiological risk; among these, the Beta-Poisson model resulted the most reliable. Thus, the Dipartimento di Scienze delle Produzioni Vegetali of the University of Bari, which has been carrying out researches on irrigation with municipal filtered wastewater for several years, considered interesting to verify if the microbial limits imposed by the italian law n.185/03 are too severe, estimating the biological risk by the probabilistic Beta-Poisson model. Results of field trials on vegetable crops irrigated by municipal filtered wastewater, processed by the Beta-Poisson model, show that the probability to get infection and/or illness is extremely low, and that the actual italian microbial limits are excessively restrictive.

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

  11. Quantum leap for treating wastewaters

    International Nuclear Information System (INIS)

    Wallace, Paula

    2012-01-01

    Full text: For many Australian food manufacturers there is increasing pressure from government agencies to reach higher standards of wastewater treatment for environmental discharge. In fact, throughout the western wolrd industrual water users are facing a similar challenge. One of the big problems is ageing pipe networks, particularly sewage pipes. Also, industrial wastewaters with high sugar-nutrient loads can cause serious damage to pipelines. This is because fermentation occurs within the wastewater, eroding and degrading the pipes, causing numerous cracks and fractures. This in turn leads to water ingress, which puts a strain on treatment plants because of the higher volume of water, especially in wet weather. Food manufacturing produces large volumes of mostly biodegradable liquid and solid waste. Wastewaters released from food manufacturing can be 'muddy', with high concentrations of suspended solids, fats, oils and grease (FOGs), and, usually, nutrients such as nitrogen. The issue for many food manufacturers is that existing wastewater treatment systems are unable to reduce the nutrient load in the biological treatment stage to a level allowing acceptable discharge. In addition, most rely on large tanks housing bacteria that are submerged in water and aerated. Aeration is energy-hungry and can create a 'sludge-cake' on top of the water, which is difficult to treat. Most existing technologies also use filters, but they foul easily and require ongoing maintenance. According to BioGill chief executive John West, the BioGill technology is groundbreaking and radically different from conventional bioreactors because the 'gills' are not submerged. Instead, the gills, composed of Nano-Ceramic Membrane sheets arranged vertically in pairs, are suspended in the air, above ground, with wastewater travelling down between them. “Fungi and bacteria, known as biomass, grow on the membranes in direct contact with the air, eating nutrients much faster than other systems

    The objective of the present study was to analyse the occurrence of dermatosis in individuals that had been exposed to cesium{sup 137} during the radioactive accident in Goiania, in 1987 and detect pre-cancerous dermatosis or those predictive of low immunity. The groups were evaluated according to the intensity of radiation they had been exposed to and then compared to a control group of people not exposed to radiation. The population exposed to the cesium{sup 137} was comprised of 109 people, who were divided into Groups I and II, according to the CNEN norms. In group I, 54 people with {<=} 20 rads exposure and/or radio lesion were included; in group II, 55 people with > 20 rads exposure were included, along with the children of group I individuals. This was a historic cohort study, that is, a retrospective study that lasted 9 years, extending from September of 1987 to August, 1996. The presence of the oncoprotein p-53 was studied in the radio lesions of 10 patients. There is no evidence of an increase in the incidence of dermatosis in the exposed groups, excepts for pyoderma in patients with radio lesions. The most frequent dermatosis were: pyoderma, pityriasis versicolor, scabies, dermatophytosis and seborrhoeic dermatitis. The results obtained were not statistically significant for the evaluation of dermatosis predictive of low immunity or precancerous lesions. The oncoprotein p-53 in individuals with radio lesion showed a 80% positivity rate and risk factor estimated in 8 times, for the test. It has proved to be useful because it represents one more option in terms of propaedeutic evaluation and suggests that one should pay close and continuous attention in order to better control the evolution of these individuals.

    Pohar, Surjeet; Hoffstetter, Sylvette; Peiffert, Didier; Luporsi, Elisabeth; Pernot, Monique

    1995-01-01

    Purpose: Radical radiotherapeutic management of vulvar cancer often incorporates brachytherapy as a portion of the treatment regimen. However, few studies using this modality alone to manage vulvar cancer have been published. Methods and Materials: Thirty four patients were treated with iridium-192 ( 192 Ir) brachytherapy for vulvar cancer between 1975 and 1993 at Centre Alexis Vautrin. Twenty-one patients were treated at first presentation when surgery was contraindicated or declined. Of these patients, 12 had International Federation of Gynecology and Obstetrics Classification Stage III or IV disease, 8 were Stage II, 1 was Stage I, and 1 was Stage 0. Thirteen patients were treated for recurrent disease. Paris system rules for implantation and dose prescription were followed. The median reference dose was 60 Gy (range 53 to 88 Gy). At the time of analysis, 10 of 34 patients were alive. Median follow-up in these 10 patients was 31 months (range: 21 months to 107 months). Fourteen of the 24 deaths were from causes other than vulvar cancer. Results: Kaplan-Meier actuarial 5-year local control was 47% (95% confidence interval (CI) = 23 to 73%) and 5-year actuarial loco-regional control was 45% (95% CI = 21 to 70%). Kaplan-Meier actuarial 5-year disease-specific survival was 56% (95% CI = 33 to 76%) and actuarial 5-year survival was 29% (95% CI = 15 to 49%). Median time to death was 14 months. Subset analysis revealed a higher actuarial 5-year local control in patients treated at first presentation than those treated for recurrence (80 vs. 19%, log rank, p = 0.04). Similarly, actuarial 5-year loco-regional control was higher in patients treated at first presentation (80 vs. 16%, log rank, p 0.01). The two groups did not differ significantly in disease-specific or overall survival. The actuarial 5-year disease specific survival of 56% is somewhat less than the expected 5-year disease-specific survival after surgery in a group having a similar proportion of early stage

    Esophageal stenting is a popular of treatment of esophageal strictures in adults. It has also been described for children with benign strictures who did not respond to standard dilatation therapy. The aim of the study was to evaluate weather esophageal stents could be used safely and effectively in the treatment of benign esophageal strictures in children. From 1993 to 2005 stenting therapy was performed in 12 children with complicated esophageal strictures. Etiologies of the strictures were caustic burns in 9 patients, postoperative strictures due to complicated esophageal atresia in 2 patients and iatrogenic esophageal injury in 1 patient. Esophageal silicon tubi, covered retrievable expandable nitinol and plastic stents were placed endoscopically. The clinical course and the long term follow up were evaluated retrospectively The stents and tubi were placed in all patients without complications and were later removed successfully. 6 patients were treated with a self expanding plastic stent. The plastic stents showed a distinct tendency to migrate but in 5/6 patients esophageal stricture was treated successfully. 3 patients were treated by a covered self expanding nitinol stent. No migration occurred. One patient was asymptomatic after therapy, one required further dilatation therapy and the third had esophageal resection. 3 patients were treated by esophageal tubi. 2 patients required surgery in the follow up, one patient is asymptomatic. The use of stenting devices in children to treat benign esophageal strictures is safe and efficient. The self expanding plastic stents had the best long term results but required high compliance of parents and children due to the tendency of stent migration. Self expanding nitinol stents are more traumatic at the extraction procedure and are useful in patients with low compliance. Recurrence of strictures occurred most often after esophageal tubi possibly due to the lack of radial expansion.

    The swelling behavior in different solvents of 4 bituminous coals with different ranks and their residues from extraction by CS{sub 2}/NMP mixed solvent (l:1 in volume) were measured. The change in swelling property of the four coals thermally treated at different temperature was observed. The results show that the swelling ratio decreases with increasing rank of coal. For lower rank bituminous coals the swelling ratios in polar solvent are higher than those in non-polar solvent, and this difference decreases with increasing rank. The cross-linking densities of the four residues decrease, and the swelling ratios increase compared with those of raw coals. The swelling ratios of the four thermally treated coals under 150{sup o}C in CS{sub 2} increase, suggesting the decrease in crosslinking density of them. When the thermal treatment temperature increases to 240{sup o}C, the swelling rations of the other three coals in NMP and CS{sub 2} increase again except gas coal, demonstrating the further decrease in crosslinking density. This result is coincident with the extraction yield change in the mixed solvent of the thermally treated coal. For example, the extraction yield of lean coal treated at 240{sup o}C increases from 6.9% to 17.3%. FT-IR results show the removal of oxygen group of the thermally treated coals. This may explain the increase in swelling ratio and extraction yield in the mixed solvent of coal after thermal treatment. The cross-linking density of the thermally treated coal decreases because of the break of hydrogen bonds due to removal of C = 0 and -OH oxygen groups during the thermal treatment, resulting in the increases of swelling ratio and extraction yield in the mixed solvent of thermally treated coal compared with those of raw coal. 15 refs., 3 figs., 6 tabs.

    With the advent of next generation reactor systems and new fuel designs, the U.S. Department of Energy (DOE) has identified the need for the resumption of transient testing of nuclear fuels. DOE has decided that the Transient Reactor Test Facility (TREAT) at Idaho National Laboratory (INL) is best suited for future testing. TREAT is a thermal neutron spectrum nuclear test facility that is designed to test nuclear fuels in transient scenarios. These specific fuels transient tests range from simple temperature transients to full fuel melt accidents. The current TREAT core is driven by highly enriched uranium (HEU) dispersed in a graphite matrix (1:10000 U-235/C atom ratio). At the center of the core, fuel is removed allowing for the insertion of an experimental test vehicle. TREAT’s design provides experimental flexibility and inherent safety during neutron pulsing. This safety stems from the graphite in the driver fuel having a strong negative temperature coefficient of reactivity resulting from a thermal Maxwellian shift with increased leakage, as well as graphite acting as a temperature sink. Air cooling is available, but is generally used post-transient for heat removal. DOE and INL have expressed a desire to develop a simulation capability that will accurately model the experiments before they are irradiated at the facility, with an emphasis on effective and safe operation while minimizing experimental time and cost. At INL, the Multi-physics Object Oriented Simulation Environment (MOOSE) has been selected as the model development framework for this work. This paper describes the results of preliminary simulations of a TREAT fuel element under transient conditions using the MOOSE-based MAMMOTH reactor physics tool.

    Nitriding of steels, using plasma environments has been practiced for many years. A lot of efforts have been put on developing new methods, such as plasma immersion ion implantation (Pl sup 3) and radio frequency (RF) plasma nitriding, for mass transfer of nitrogen into the surface of the work piece. This article presents the results obtained from an in depth investigation of the surface morphology of the treated samples, carried out using an atomic force microscope. Samples from a microalloyed steel, were treated by both methods for 5 hours at different temperatures ranging from 350 to 550 sup d eg sup C in 75% N sub 2 -25% H sub 2 atmosphere. It has been found that the surface of the samples treated by PI sup 3 technique, although having more favorable properties, were rougher than the surfaces treated by RF plasma nitriding.

    Laboratory effectiveness tests have been developed for four classes of oil spill treating agents: solidifiers, demulsifying agents, surface-washing agents and dispersants. Several treating agent products in these four categories have been tested for effectiveness. The aquatic toxicity of these agents is an important factor and has been measured for many products. These results are presented. Solidifiers or gelling agents solidify oil. Test results show that solidifiers require between 16% and 200% of agent by weight compared to the oil. De-emulsifying agents or emulsion breakers prevent the formation of or break water-in-oil emulsions. Surfactant-containing materials are of two types, surface-washing agents and dispersants. Testing has shown that effectiveness is orthogonal for these two types of treating agents. Tests of surface washing agents show that only a few agents have effectiveness of 25 to 55%, where this is defined as the percentage of oil removed from a test surface. Dispersant effectiveness results using the swirling flask test are reported. Heavy oils show effectiveness values of about 1%, medium crudes of about 10%, light crude oils of about 30% and very light oils of about 90%

    The aim of this study is to assess the risk of avascular osteonecrosis (AVN) of the femoral head in patients treated for Hodgkin's disease (HD), in relation to the type of treatment they have received. For this purpose, a cohort of 1391 patients treated for HD at University of Rome between 1972 and 1996 was divided into 2 groups according to their initial treatment. The first group contained 784 patients treated, at the onset of HD, either with chemotherapy (CT) containing steroids, combined in some cases with subdiaphragmatic radiotherapy (RT), or with subdiaphragmatic RT combined with CT without steroids. The second group was made up of 607 patients who had received, initially, supradiaphragmatic RT alone or supradiaphragmatic RT combined with CT without steroids. For the purpose of this study, only the 784 patients belonging to the first group were observed for the appearance of AVN, which occurred in 9 cases. The period of time which elapsed between the end of treatment and the radiological evidence of AVN ranged from 23 to 97 months, with an average of 35 months. Because the number of cases of AVN was so small, the pathogenesis of this complication could not be identified. (au)

    The Transient Reactor Test (TREAT) facility was designed and built in the late 1950s at Argonne National Laboratory (ANL) to provide a transient reactor for safety experiments on samples of reactor fuels. It first operated in 1959. Throughout its history, experiments conducted in TREAT have been important in establishing the behavior of a wide variety of reactor fuel elements under conditions predicted to occur in reactor accidents ranging from mild off-normal transients to hypothetical core disruptive accidents. For much of its history, TREAT was used primarily to test liquid-metal reactor fuel elements, initially for the Experimental Breeder Reactor-II (EBR-II), then for the Fast Flux Test Facility (FFTF), the Clinch River Breeder Reactor Plant (CRBRP), the British Prototype Fast Reactor (PFR), and finally for the Integral Fast Reactor (IFR). Both oxide and metal elements were tested in dry capsules and in flowing sodium loops. The data obtained were instrumental in establishing the behavior of the fuel under off-normal and accident conditions, a necessary part of the safety analysis of the various reactors. In addition, TREAT was used to test light water reactor (LWR) elements in a steam environment to obtain fission product release data under meltdown conditions. Studies are now under way on applications of TREAT to testing of the behavior of high-burnup LWR elements under reactivity-initiated accident (RIA) conditions using a high-pressure water loop

    A wastewater disinfection system developed by a Canadian company, Trojan Technologies Inc., was discussed. Disinfection for pathogen reduction prior to discharge of treated municipal wastewater back into rivers and lakes has been either ignored or treated by the use of chemicals. In 1979 the first pilot ultraviolet (UV) wastewater disinfection system was established. Since then, over 500 municipal UV installations have been commissioned. The largest installation can process 212 million gallons of water per day. The advantages of UV as a disinfectant are: (1) It is more effective than chlorine. (2) There are no mutagenic/carcinogenic byproducts formed with UV. (3) No toxic chemical residuals are discharged. (4) UV is safe to both the operators and the public. (5) It is cost effective. Europe has not been as active in wastewater disinfection as has North America. One result of the absence of wastewater disinfection in Europe is that the Rhine River, for example, carries 50 million salmonella per second. Disinfection of wastewater effluents is, of course, indispensable in protecting our drinking water supply. 2 figs.

    The potential feasibility of treated and untreated activated carbon for removal of methylene blue from aqueous solution was investigated. The effects of various experimental parameters such as contact time, solution pH and adsorbent dosage were investigated. The extent of methylene blue removal increased with the increased in contact time, solution pH and amount of adsorbent used. Adsorption data was better fitted to the Langmuir isotherm. The results in this study indicated that the treated activated carbon was an attractive candidate for removing organic dye of methylene blue which shows great reduction of colour while reducing the time contact to achieve equilibrium.

    Testicular cancer affects men mostly in their reproductive age with a cure rate over 90% and fertility is one of the main concerns of survivors. To further elucidate the question of fertility after treatment for testicular cancer, we performed a survey in patients treated in our institution. We sent a questionnaire to patients treated for testicular cancer at our institute from 1976 to 2002 (n = 490) of whom 297 (60.6%) responded. We considered the patients to have conserved fertility if they had children after treatment without assisted reproductive technologies. Before treatment 119/297 (40.1%) of patients and after treatment 150/297 (50.5%) of patients tried to have children (p = 0.019). Of 119 patients who tried to have children before treatment for testicular cancer 98 (82.4%) succeeded and 74/150 (49.3%) were successful after treatment (p years. The post-treatment fatherhood in patients treated with surgery only (orchidectomy +/- retroperitoneal lymphnode dissection-RPLND) was 59%, in those with additional radiotherapy 68%, and chemotherapy 50% (p = 0.233). Fertility rate in patients where a non nerve sparing RPLND was performed was only 37%, 62% in patients with nerve sapring RPLND, and 77% in patients where RPLND was not performed (p Fertility rate after treatment for testicular cancer is reduced. From our data, the most important treatment modality that influences fertility is non nerve sparing RPLND that should be avoided whenever possible in order improve the quality of life our patients.

    2008-01-01

    Full Text Available The field of Urology in Medicine has witnessed tremendous advancement in technology and in accordance with it. Endourology has taken a leap ahead in terms of stone management. Most of the stones could be treated with semi-rigid ureteroscopy, percutaneous nephrolithotomy (PNL and ESWL and some would need Flexible ureteroscopy. Flexible ureteroscopy has been primarily indicated to treat ESWL resistant renal stones but with changes in the technology of incorporating secondary active deflection and availability of laser fibres, its horizon for indications to treat stones is being widened. Though Flexible ureteroscopy is being used to treat stones of various sizes and locations, its cost effectiveness is debatable. Should it be used ubiquitously to treat stones amenable to PNL or ESWL is a big question we need to answer. As of now true indications of Flexible ureteroscopy are limited and there is an urgent need for a randomized trial to compare its efficacy with ESWL and PNL for renal and upper ureteric stones.

    Forty-two survivors treated at an age of 2-16 years for brain tumors or leukemia were, 4-21 years after treatment, subjected to an extensive follow-up investigation, including physical examination and interview; 35 of them also had endocrinological and 33 psychological evaluation. Hormonal deficiencies were found in about two-thirds of patients and were most common in those treated for brain tumors. The great majority had verbal intelligence quotient (VIQ) within normal range. Also, the performance intelligence quotients (PIQ) were normal in most patients. However, the results suggested that the primary intellectual capacity in children treated for cancer was not being fully utilized, their PIQ being on the average higher than their VIQ; this tendency was especially pronounced in the leukemia patients.

  3. Approximate method for treating dispersion in one-way quantum channels

    Stace, T. M.; Wiseman, H. M.

    2006-01-01

    Coupling the output of a source quantum system into a target quantum system is easily treated by cascaded systems theory if the intervening quantum channel is dispersionless. However, dispersion may be important in some transfer protocols, especially in solid-state systems. In this paper we show how to generalize cascaded systems theory to treat such dispersion, provided it is not too strong. We show that the technique also works for fermionic systems with a low flux, and can be extended to treat fermionic systems with large flux. To test our theory, we calculate the effect of dispersion on the fidelity of a simple protocol of quantum state transfer. We find good agreement with an approximate analytical theory that had been previously developed for this example

    Ahmed A. Tayel

    Full Text Available Candida albicans, one of the most dreadful fungal pathogens threatening humans, could not be easily prevented. The anticandidal activity of oak gall extract, Quercus infectoria (QIE, was investigated as a potential natural alternative to synthetic and chemical fungicides. QIE anticandidal potentiality was confirmed using both qualitative and quantitative assays. Cotton textiles were treated with QIE and then evaluated as anticandidal fabrics. QIE-treated textiles had a potent anticandidal activity, which could completely inhibit the inoculated C. albicans cells. The durability of anticandidal activity in QIE-treated textiles almost completely disappeared after the fourth laundering cycle. QIE could be recommended, however, as a potent anticandidal agent for preparing antiseptic solutions and emulsions and as a finishing agent for manufacturing anticandidal disposable diapers and hygienic clothes.

    Full Text Available This article is a part of a larger study comparing various aspects of policies on plagiarism in two university contexts. It compares policies on plagiarism in universities in Australia and Indonesia. The results of this comparative study showed that Australian and Indonesian universities treat plagiarism differently. Australian universities treat plagiarism explicitly in their university policies. In Australian universities, plagiarism is defined clearly and forms of plagiarism are explained thoroughly, policies on plagiarism are informed to all university academic members, and there are mechanisms to manage cases related to plagiarism. In contrast, not all Indonesian universities treat plagiarism directly. Some universities depend on religious morality and academic ethics in dealing with plagiarism. Accordingly, this article recommends the explicit treatment of plagiarism in Indonesian universities.

    2011-05-01

    An integrated fluidized bed bioreactor (iFBBR) was designed to incorporate an aerobic sponge FBBR (ASB-FBBR) into an anoxic granular activated carbon FBBR (GAC-FBBR). This iFBBR was operated with and without adding a new starch based flocculant (NSBF) to treat synthetic primary treated sewage effluent (PTSE). The NSBF contains starch based cationic flocculants and trace nutrients. The results indicate that the iFBBR with NSBF addition could remove more than 93% dissolved organic carbon (DOC), 61% total nitrogen (T-N) and 60% total phosphorus (T-P) at just a very short hydraulic retention time of 50 min. The optimum frequency of adding NSBF to the iFFBR is four times per day. As a pretreatment to microfiltration, the iFFBR could increase 5L/m(2)h of critical flux thus reducing the membrane fouling. In addition, better microbial activity was also observed with high DO consumption (>66%) and specific oxygen uptake rate (>35 mg O(2)/g VSS h). Copyright © 2010 Elsevier Ltd. All rights reserved.

    To compare, with the use of chest radiographic findings, improvement and complications in newborns treated with exogenous surfactant for hyaline membrane disease (HMD), and an untreated control group. Thirty-six patients with HMD were randomly assigned to a control group (n=18) or surfactant treated group (n=18). As part of an initial evaluation of their pulmonary status, we then performed a retrospective statistical analysis of chest radiographic findings obtained in exogenous surfactant treated and untreated infants within the first 90 minutes of life. Subsequent examinations were performed at less than 24 hours of age. Chest radiograph before treatment showed no significant differences between the two groups, but significant improvement was noted in the surfactant treated group, in contrast to the control group. The most common chest radiographic finding after surfactant administration was uniform (n=15) or disproportionate (n=2) improvement of pulmonary aeration. Patent ductus arteriosus developed in three treated neonates and in four cases in the control group. Air leak occurred in three cases in the treated group and in five cases in the control group. In one treated patient pulmonary hemorrhage developed and intracranial hemorrhage occurred in three treated neonates and in four cases in the control group. Bronchopulmonary dysplasia was developed in 6 cases of treated group and 3 cases of control group. A chest radiograph is considered to be helpful in the evaluation of improvement and complications of HMD in infants treated with surfactant

The finely crushed shale with a higher content of moisture is brought into contact with finely crushed shale of a lower content of moisture, and thereby serves as kernel material during the formation of the nodules or similar shapes.

    In the management of subarachnoid hemorrhage (SAH), the potential for early complications and the centralization of limited resources often challenge the delivery of timely neurosurgical care. We sought to determine the impact of proximity to the accepting neurosurgical centre on outcomes following aneurysmal SAH. Using administrative data, we analyzed patients undergoing treatment for aneurysmal subarachnoid hemorrhage at neurosurgical centres in Ontario between 1995 and 2004. We compared mortality for patients receiving treatment at a centre in their county (in-county) versus those treated from outside counties (out-of-county). We also examined the impact of distance from the patient's residence to the treating centre. The mortality rates were significantly lower for in-county versus out-of-county patients (23.5% vs. 27.6%, p=0.009). This advantage remained significant after adjusting for potential confounders (HR=0.84, p=0.01). The relationship between distance from the treating centre and mortality was biphasic. Under 300 km, mortality increased with increasing distance. Over 300 km, a survival benefit was observed. Proximity to the treating neurosurgical centre impacts survival after aneurysmal SAH. These results have significant implications for the triage of these critically ill patients.

    Continuous treatment with ivermectin from birth to puberty advanced sexual maturation by 3.7 wk in Holstein heifers grazing pastures naturally infected with nematodes. Every 14 d jugular blood samples were taken from birth to 45 wk of age from all heifers. No differences in serum FSH, estradiol, or thyroxine levels were observed during the trial between the treated and untreated group. Mean LH levels were diminished in untreated heifers 4 wk before the first estrus and the amplitude of LH pulses was augmented in treated heifers when puberty was reached. Serum IGF-I levels increased from birth to 22 wk of age and then reached a plateau in both groups, but levels were consistently higher in treated heifers from 26 wk of age onward. Body weight gain was retarded in parasitized heifers and IGF-I values were positively correlated with body weight only during the first 20 wk of life. We suggest that enhanced prepubertal IGF-I levels in conjunction with increased prepubertal LH levels and pubertal LH pulse amplitude might be involved in the accelerated somatic maturation and in puberty advancement observed in ivermectin-treated heifers.

  14. Residual Renal Function in Children Treated with Chronic Peritoneal Dialysis

    Full Text Available Residual renal function (RRF in patients with end-stage renal disease (ESRD receiving renal replacement therapy is defined as the ability of native kidneys to eliminate water and uremic toxins. Preserved RRF improves survival and quality of life in adult ESRD patients treated with peritoneal dialysis. In children, RRF was shown not only to help preserve adequacy of renal replacement therapy but also to accelerate growth rate, improve nutrition and blood pressure control, reduce the risk of adverse myocardial changes, facilitate treatment of anemia and calcium-phosphorus balance abnormalities, and result in reduced serum and dialysate fluid levels of advanced glycation end-products. Factors contributing to RRF loss in children treated with peritoneal dialysis include the underlying renal disease such as hemolytic-uremic syndrome and hereditary nephropathy, small urine volume, severe proteinuria at the initiation of renal replacement therapy, and hypertension. Several approaches can be suggested to decrease the rate of RRF loss in pediatric patients treated with chronic peritoneal dialysis: potentially nephrotoxic drugs (e.g., aminoglycosides, episodes of hypotension, and uncontrolled hypertension should be avoided, urinary tract infections should be treated promptly, and loop diuretics may be used to increase salt and water excretion.

    The purpose of this study was to determine if non-specific COX inhibition could extend pore lifetime in hairless guinea pigs following microneedle treatment. Hairless guinea pigs were treated with microneedle arrays ± daily application of Solaraze® gel (3% diclofenac sodium (non-specific COX inhibitor) and 2.5% hyaluronic acid); transepidermal water loss was utilized to evaluate pore lifetime. To examine the permeation of naltrexone, additional guinea pigs were treated with microneedles ± daily Solaraze® gel followed by application of a 16% transdermal naltrexone patch; pharmacokinetic analysis of plasma naltrexone levels was performed. Histological analysis was employed to visualize morphological changes following microneedle and Solaraze® treatment. Animals treated with microneedles + Solaraze® displayed extended pore lifetime (determined by transepidermal water loss measurements) for up to 7 days. Enhanced naltrexone permeation was also observed for an extended amount of time in animals treated with microneedles + Solaraze®. No morphological changes resulting from microneedle treatment or COX inhibition were noted. Non-specific COX inhibition is an effective means of extending pore lifetime following microneedle treatment in hairless guinea pigs. This may have clinical implications for extending transdermal patch wear time and therefore increasing patient compliance with therapy.

    Highlights: ► Investigate detailed structural changes of heat-treated wood due to weathering. ► Identify connection between physical structural changes and chemical degradation. ► Study effect of heat treatment conditions on weathering degradation process. - Abstract: Effect of artificial weathering on the surface structural changes of birch (Betule papyrifera) wood, heat-treated to different temperatures, was studied using the fluorescence microscopy and the scanning electron microscopy (SEM). Changes in the chemical structure of wood components were analyzed by FTIR in order to understand the mechanism of degradation taking place due to heat treatment and artificial weathering. The results are compared with those of the untreated (kiln-dried) birch. The SEM analysis results show that the effect of weathering on the cell wall of the untreated birch surface is more than that of heat-treated samples. The FTIR spectroscopy results indicate that lignin is the most sensitive component of heat-treated birch to the weathering degradation process. Elimination of the amorphous and highly crystallised cellulose is observed for both heat-treated and untreated wood during weathering. It is also observed that heat treatment increases the lignin and crystallised cellulose contents, which to some extent protects heat-treated birch against degradation due to weathering.

    Color stability of swine blood was studied over 12 weeks of storage in plastic bags, after pH (7.40, 6.70, or 6.00) adjustment, saturation with carbon monoxide (CO) and spray-drying. CO-treated dried blood presented a redder color and higher reflectance between 610 and 700 nm, compared to a brownish-red color and lower reflectance of untreated samples. As indicated by reflectance spectra, blood pH adjustment did not influence (P>0.05) the initial color of dried blood but influenced (Pvalues, which was more pronounced in polyethylene (OTR=4130 cm(3)/m(2)/day/atm) packaged samples. After 12 weeks of storage, CO-treated samples packaged in high OTR bags presented color indexes similar to those of the untreated dried samples. CO-treated samples packaged in nylon-polyethylene (OTR=30-60 cm(3)/m(2)/day/atm) bags showed a smaller rate of discoloration and color difference (DeltaE(*)) between the CO-treated and untreated samples. Even with some darkening, packaging CO-treated dry blood in low OTR bags still gives an acceptable reddish color after 12 weeks of storage while untreated dry blood has a brownish color just after drying.

    2014-12-01

    Full Text Available Background Coronary heart disease (CHD is a major health concern, affecting nearly half the middle-age population and responsible for nearly one-third of all deaths. Clinicians have several major responsibilities beyond diagnosing CHD, such as risk stratification of patients for major adverse cardiac events (MACE and treating risks, as well as the patient. This second of a two-part review series discusses treating risk factors, including autonomic dysfunction, and expected outcomes. Methods Therapies for treating cardiac mortality risks including cardiovascular autonomic neuropathy (CAN, are discussed. Results While risk factors effectively target high-risk patients, a large number of individuals who will develop complications from heart disease are not identified by current scoring systems. Many patients with heart conditions, who appear to be well-managed by traditional therapies, experience MACE. Parasympathetic and Sympathetic (P&S function testing provides more information and has the potential to further aid doctors in individualizing and titrating therapy to minimize risk. Advanced autonomic dysfunction (AAD and its more severe form cardiovascular autonomic neuropathy have been strongly associated with an elevated risk of cardiac mortality and are diagnosable through autonomic testing. This additional information includes patient-specific physiologic measures, such as sympathovagal balance (SB. Studies have shown that establishing and maintaining proper SB minimizes morbidity and mortality risk. Conclusions P&S testing promotes primary prevention, treating subclinical disease states, as well as secondary prevention, thereby improving patient outcomes through (1 maintaining wellness, (2 preventing symptoms and disorder and (3 treating subclinical manifestations (autonomic dysfunction, as well as (4 disease and symptoms (autonomic neuropathy.

    The aim of this study was to evaluate the effectiveness of different nanoparticles-based solutions for dentin permeability reduction and to determine the viscoelastic performance of cervical dentin after their application. Four experimental nanoparticle solutions based on zinc, calcium or doxycycline-loaded polymeric nanoparticles (NPs) were applied on citric acid etched dentin, to facilitate the occlusion and the reduction of the fluid flow at the dentinal tubules. After 24 h and 7 d of storage, cervical dentin was evaluated for fluid filtration. Field emission scanning electron microscopy, energy dispersive analysis, AFM and Nano-DMA analysis were also performed. Complex, storage, loss modulus and tan delta (δ) were assessed. Doxycycline-loaded NPs impaired tubule occlusion and fluid flow reduction trough dentin. Tubules were 100% occluded in dentin treated with calcium-loaded NPs or zinc-loaded NPs, analyzed at 7 d. Dentin treated with both zinc-NPs and calcium-NPs attained the highest reduction of dentinal fluid flow. Moreover, when treating dentin with zinc-NPs, complex modulus values attained at intertubular and peritubular dentin were higher than those obtained after applying calcium-NPs. Zinc-NPs are then supposed to fasten active dentin remodeling, with increased maturity and high mechanical properties. Zinc-based nanoparticles are then proposed for effective dentin remineralization and tubular occlusion. Further research to finally prove for clinical benefits in patients with dentin hypersensitivity using Zn-doped nanoparticles is encouraged. Erosion from acids provokes dentin hypersensitivity (DH) which presents with intense pain of short duration. Open dentinal tubules and demineralization favor DH. Nanogels based on Ca-nanoparticles and Zn-nanoparticles produced an efficient reduction of fluid flow. Dentinal tubules were filled by precipitation of induced calcium-phosphate deposits. When treating dentin with Zn-nanoparticles, complex modulus

    The purpose of these guidelines is to assist health care institutions establish protocols for the management of patients treated with iodine-131. These guidelines are written primarily for the use of Na 131 I in the treatment of benign and malignant thyroid disease. The principles have some application for the use of complex 131 I-labelled radiopharmaceuticals in that the treated patient will become a temporary radiation source and since contamination with body fluids of treated patients must be guarded against. The document outlines radiation protection and logistical concerns associated with the management of 131 I patients before, during and after therapy. These concerns include the safety of health care personnel, visitors, and any other persons who are at risk; and protection of the environment. (L.L.) 23 refs., 2 tabs

    Osteoporosis is a chronic disease, carrying an elevated risk of fractures, morbidity, and death. Long-term treatment may be required, but the long-term risks with osteoporosis drugs remain incompletely understood. The competing risk of death may be a barrier to treating the oldest, yet this may...... not be rational if the risk of death is reduced by treatment. It is difficult to devise goal-directed long-term strategies for managing osteoporosis without firm information about residual life expectancy in treated patients.

    It is well known that itai-itai disease with the osteopathy is broken out among multiparas, 40 years of age and up Japanese residents. In this paper we described an experimental study of effect of pregnancy on cadmium treated rats. Female mature rats were administered drinking water containing 50 and 200 ppm cadmium as CdCl/sub 2/. During 180 days of the experiment, three times of pregnancy were succesful, though slight depression of body weight gain was noticed in the 200 ppm group. The cadmium was accumulated in the kidneys, liver and bone proportionally to the amount of cadmium administered. No significant change was recognized in serum calcium, phosphorus and alkaline phosphatase levels after 180 days. Though cadmium 200 ppm treated rats showed slight histological lesions in the proximal convoluted tubules of the kidney, there appeared to be no osteomalacia including excess formation of osteoid tissue.

    Full Text Available Water-repellent soils have a potential as alternative construction materials that will improve conventional geotechnical structures. In this study, the potential of chemically treated water-repellent kaolin clay as a landfill cover material is explored by examining its characteristics including hydraulic and mechanical properties. In order to provide water repellency to the kaolin clay, the surface of clay particle is modified with organosilanes in concentrations (CO ranging from 0.5% to 10% by weight. As the CO increases, the specific gravity of treated clay tends to decrease, whereas the total organic carbon content of the treated clay tends to increase. The soil-water contact angle increases with an increase in CO until CO = 2.5%, and then maintains an almost constant value (≈134.0°. Resistance to water infiltration is improved by organosilane treatment under low hydrostatic pressure. However, water infiltration resistance under high hydrostatic pressure is reduced or exacerbated to the level of untreated clay. The maximum compacted dry weight density decreases with increasing CO. As the CO increases, the small strain shear modulus increases, whereas the effect of organosilane treatment on the constrained modulus is minimal. The results indicate that water-repellent kaolin clay possesses excellent engineering characteristics for a landfill cover material.

    2006-07-01

    Full Text Available An experiment was conducted to evaluate the dry matter disappearance and potential degradability of urea-treated rice straw (UTS. Five kg of non-glutinous rice straw (RS was chopped and treated with urea solution and kept in a double sheet polyethylene bag. The ratio of RS to water was 1:1. The urea concentration was 4, 5 and 6% by weight of RS and the duration of treatment was 7, 14 and 21 days. There were 9 treatment combinations with 3 replications. The dry and ground UTS were weighted into nylon bags and incubated in 3 fistulated cows. The dry matter disappearance was detected at different incubation times. The result showed that CP content of UTS was higher than RS and the amount increased with the increasing level of urea. The longer treatment duration caused depletion in CP content. Nitrogen was lost as ammonia when UTS was dried, which led to the lower CP than fresh UTS. The duration of treating of 7, 14 and 21 days caused no-significant difference in potential degradability (71.61±2.59, 72.38±2.80 and 72.70±2.44%, respectively, P> 0.05, but 6% UTS has higher potential degradability than 4 % UTS (74.24± 0.53 and 69.84±1.03%, respectively, P< 0.05

    from the PubMed and SciELO was carried out using the keywords autoinflammatory syndromes and child. SUMMARY OF THE FINDINGS: The hereditary autoinflammatory syndromes are caused by monogenic defects of innate immunity and are classified as primary immunodeficiencies. These syndromes are characterized by recurrent or persistent systemic inflammatory symptoms and must be distinguished from infectious diseases, autoimmune diseases, and other primary immunodeficiencies. This review describes the epidemiological, clinical and laboratory features, prognosis, and treatment of the main autoinflammatory syndromes, namely: familial Mediterranean fever; TNF receptor associated periodic syndrome; the cryopyrinopathies; mevalonate kinase deficiency; pediatric granulomatous arthritis; pyogenic arthritis, pyoderma gangrenosum and acne syndrome; Majeed syndrome; and deficiency of interleukin 1 receptor antagonist. The cryopyrinopathies discussed include neonatal-onset multisystem inflammatory disease (also known as chronic infantile neurologic, cutaneous and articular syndrome Muckle-Wells syndrome, and familial cold autoinflammatory syndrome. CONCLUSIONS: Pediatricians must recognize the clinical features of the most prevalent autoinflammatory syndromes. Early referral to a pediatric rheumatologist may allow early diagnosis and institution of treatment, with improvement in the quality of life of these patients.

    Kraft lignin (KL) was thermally treated at 500 to 1000 °C in an inert atmosphere. Carbon nanostructure parameters of thermally treated KL in terms of amorphous carbon fraction, aromaticity, and carbon nanocrystallites lateral size ( L a ), thickness ( L c ), and interlayer space ( d 002 ) were analyzed quantitatively using X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy. Experimental results indicated that increasing temperature reduced amorphous carbon but increased aromaticity in thermally treated KL materials. The L c value of thermally treated KL materials averaged 0.85 nm and did not change with temperature. The d 002 value decreased from 3.56 Å at 500 °C to 3.49 Å at 1000 °C. The L a value increased from 0.7 to 1.4 nm as temperature increased from 500 to 1000 °C. A nanostructure model was proposed to describe thermally treated KL under 1000 °C. The thermal stability of heat treated KL increased with temperature rising from 500 to 800 °C.

    The most common and problematic side effect of statins is myopathy. To date, the patho-physiological mechanisms of statin myotoxicity are still not clearly understood. In previous studies, we showed that acute application in vitro of simvastatin caused impairment of mitochondrial function and dysfunction of calcium homeostasis in human and rat healthy muscle samples. We thus evaluated in the present study, mitochondrial function and calcium signaling in muscles of patients treated with statins, who present or not muscle symptoms, by oxygraphy and recording of calcium sparks, respectively. Patients treated with statins showed impairment of mitochondrial respiration that involved mainly the complex I of the respiratory chain and altered frequency and amplitude of calcium sparks. The muscle problems observed in statin-treated patients appear thus to be related to impairment of mitochondrial function and muscle calcium homeostasis, confirming the results we previously reported in vitro. -- Highlights: ► The most common and problematic side effect of statins is myopathy. ► Patients treated with statins showed impairment of mitochondrial respiration. ► Statins-treated patients showed altered frequency and amplitude of calcium sparks.

    The present study was undertaken to evaluate the frequency, characteristics and actual risk of secondary acute non lymphoid leukemia (s-ANLL) in 141 patients treated for non Hodgkin's lymphoma with different modalities. One hundred and twenty-four patients received chemotherapy according to PROVECIP protocol (9). Of these, 15 also received as induction treatment a local nodal irradiation and 33 an extended field radiotherapy. Seventeen out of 141 were treated by total body irradiation. Of these, 15 relapsed and received salvage chemotherapy. Sixteen of the 124 patients trated with PROVECIP also underwent different chemotherapeutic programs as salvage treatment. Of the entire population studied, 2 patients significantly affected the occurrence of s-ANLL, since both leukemias occurred in patients treated with total body irradiation, given alone or followed by chemotherapy. The actuarial risk at 8 years was 5.24% in the whole group, whereas it greatly increased in the group of patients treated with total body irradiation (24%). Conversely, no risk was found in the group treated with PROVECIP, alone, with additional chemotherapy, or with associated local or extended field radiotherapy

    Full Text Available Treatment of palm oil mill effluent (POME has always been a topic of research in Malaysia. This effluent that is extremely rich in organic content needs to be properly treated to minimize environmental hazards before it is released into watercourses. The common practice for treating POME in Malaysia involves a combination of aerobic and anaerobic methods. The purpose of tertiary treatment is to allow the treated water to be reused in the mill operations for other purposes such as feed water. The proposed treatment will also ensure the industry to meet a more stringent discharge standard in terms of the BOD, COD and nitrogen values. In this study membrane ultrafiltration is used as the tertiary treatment method. Before the actual membrane operation was conducted, the samples were pre-treated using three separate method namely filtration, centrifugation and coagulation. It was found that the combination of filtrationultrafiltration treatment POME produced the best-treated sample quality in terms of pollutant contents elimination, namely % BOD, % COD and % nitrogen removal.

    Full Text Available The objective of this work was to investigate the resistance of three Indonesian wood species to termite attack. Samples from sengon (Falcataria moluccana, mangium (Acacia mangium, and pine (Pinus merkusii were treated with polystyrene at loading levels of 26.0%, 8.6%, and 7.7%, respectively. Treated and untreated samples were exposed to environmental conditions in the field for 3 months. Untreated specimens of sengon, mangium, and pine had resistance ratings of 3.0, 4.6, and 2.4, respectively, based on a 10-point scale from 0 (no resistance to 10 (complete or near-complete resistance. Corresponding resistance values of 7.8, 7.2, and 8.2 were determined for specimens treated with polystyrene. Overall weight loss values of 50.3%, 23.3%, and 66.4% were found for untreated sengon, mangium, and pine samples, respectively; for treated samples, the values were 7.6%, 14.4%, and 5.1%, respectively. Based on the findings in this study, overall resistance to termite attack was higher for treated samples compared to untreated samples.

    The most common and problematic side effect of statins is myopathy. To date, the patho-physiological mechanisms of statin myotoxicity are still not clearly understood. In previous studies, we showed that acute application in vitro of simvastatin caused impairment of mitochondrial function and dysfunction of calcium homeostasis in human and rat healthy muscle samples. We thus evaluated in the present study, mitochondrial function and calcium signaling in muscles of patients treated with statins, who present or not muscle symptoms, by oxygraphy and recording of calcium sparks, respectively. Patients treated with statins showed impairment of mitochondrial respiration that involved mainly the complex I of the respiratory chain and altered frequency and amplitude of calcium sparks. The muscle problems observed in statin-treated patients appear thus to be related to impairment of mitochondrial function and muscle calcium homeostasis, confirming the results we previously reported in vitro. -- Highlights: ► The most common and problematic side effect of statins is myopathy. ► Patients treated with statins showed impairment of mitochondrial respiration. ► Statins-treated patients showed altered frequency and amplitude of calcium sparks.

    We showed that 2.1% of 233 pieces of lumber debris after the Great East Japan Earthquake was chromated copper arsenate (CCA)-treated wood. Since hexavalent chromium (Cr), copper (Cu) and pentavalent arsenic (As) in the debris may be diffused in the air via incineration, we exposed human lung normal (BEAS-2B) and carcinoma (A549) cells to Cr, Cu and As at the molar ratio in a representative CCA-treated wood. Co-exposure to 0.10 μM Cr and 0.06 μM As, which solely had no effect on colony formation, synergistically promoted colony formation in BEAS-2B cells, but not A549 cells, with activation of the PI3K/AKT pathway. Sole exposure and co-exposure to Cu showed limited effects. Since previous reports showed Cr and As concentrations to which human lungs might be exposed, our results suggest the importance to avoid diffusion of Cr and As in the air via incineration of debris including CCA-treated wood after the disaster. - Highlights: • CCA-treated wood was found in debris after the Great East Japan Earthquake in 2011. • Carcinogenic risk of CCA-treated woods was evaluated with human lung cell lines. • Co-exposure to Cr and As synergistically promoted colony formation. • Co-exposure to Cr and As synergistically activated the PI3/AKT pathway. • Effects of sole exposure and co-exposure to Cu on colony formation were limited. - Co-exposure to Cr and As, but not Cu, in CCA-treated wood debris from the Great East Japan Earthquake showed carcinogenicity in vitro.

    We have performed high-pressure high-temperature (HPHT) treatments of high quality single-walled carbon nanotubes (SWCNTs) over a wide pressure-temperature range up to 13 GPa-873 K and have investigated the hardness of the HPHT-treated SWCNTs using a nanoindentation technique. It was found that the hardness of the SWCNTs treated at pressures greater than 11 GPa and at temperatures higher than 773 K is about 10 times greater than that of the SWCNTs treated at low temperature. It was also found that the hardness change of the SWCNTs is related to the structural change by the HPHT treatments which was based on synchrotron X-ray diffraction measurements

    The role the human immunodeficiency virus (HIV) and antiretroviral treatment on endothelial activation, and the subsequent relationship with cardiovascular disease, is not well understood. We investigated endothelial activation, inflammatory and cardiometabolic profiles, and measures of vascular structure and function of 66 antiretroviral treated (ART), 78 never-treated (no-ART) HIV infected and 165 HIV free Africans. Blood samples were obtained for biochemical analysis and blood pressure, pulse wave velocity (PWV) and carotid intima-media thickness (IMT) measurements were performed. The HIV infection duration was at least five years and the treatment 2.86±0.13 years. The intracellular adhesion molecule (ICAM) and vascular cell adhesion molecule (VCAM) levels were elevated in the HIV infected groups compared to the controls. The odds of higher adhesion molecule levels were increased when HIV infected (especially in the no-ART group); OR no-ART vs. no-HIV: ICAM 3.92 (2.2-7.0); VCAM 16.2 (7.5-35). ICAM and VCAM associated with HIV status and interleukin-6 (IL-6) in the total group (all pART: β=-0.28, p=0.01; ART: β=-0.22, p=0.07) and TC (no-ART: β=-0.36, pART: β=-0.27, p=0.03). The ART group had an unfavourable lipid profile compared to the no-ART group. The inflammatory markers (C-reactive protein (CRP) and IL-6), PWV and IMT did not differ between the three groups. HIV infected Africans showed endothelial activation when compared to HIV free controls. The endothelial activation was not accompanied by increased inflammation (as measured with CRP and IL-6), arterial stiffness or sub-clinical atherosclerosis. Copyright © 2015 Elsevier Ireland Ltd.

    There have been no reports of primary leiomyosarcoma of the stomach treated by endoscopic submucosal dissection (ESD). We report an extremely rare case of gastric leiomyosarcoma that was successfully treated by ESD. An asymptomatic 74-year-old female underwent esophagogastroduodenoscopy for screening in December 2013. A centrally depressed submucosal tumor 10 mm in diameter was detected at the posterior wall of the upper gastric body. Follow-up esophagogastroduodenoscopy conducted 5 months later showed that the tumor diameter had increased to 15 mm. Endoscopic ultrasound revealed a hypoechoic mass located in the second to the middle of the third layer. Endoscopic ultrasound-guided fine-needle aspiration demonstrated a myogenic tumor. The tumor was completely resected by ESD without complications. Immunohistopathological diagnosis of the resected specimen was gastric leiomyosarcoma derived from the muscularis mucosae, with negative lateral and vertical margins. No local recurrence or metastasis has been detected at 36 months after ESD. This is the first report of gastric leiomyosarcoma treated by ESD in the English language literature.

    2014-08-01

    Full Text Available This work describes the electrical investigation of paclitaxel-treated HeLa cells using a custom-made microfluidic biosensor for whole cell analysis in continuous flow. We apply the method of differential electrical impedance spectroscopy to treated HeLa cells in order to elucidate the changes in electrical properties compared with non-treated cells. We found that our microfluidic system was able to distinguish between treated and non-treated cells. Furthermore, we utilize a model for electrical impedance spectroscopy in order to perform a theoretical study to clarify our results. This study focuses on investigating the changes in the electrical properties of the cell membrane caused by the effect of paclitaxel. We observe good agreement between the model and the obtained results. This establishes the proof-of-concept for the application in cell drug therapy.

    Full Text Available ABSTRACT The objective of this research was to investigate the effects of irrigation with treated wastewater and nitrogen (N fertilization on the chemical characteristics of a Haplustalf soil cultivated with cotton. An experiment was conducted in a greenhouse in a completely randomized design with four replicates, and arranged in a 5 x 4 factorial. Five doses of N fertilization (0, 45, 90, 135 and 180 kg ha-1 and four sources of irrigation water (freshwater, wastewater treated by an anaerobic reactor, wastewater treated by an anaerobic reactor and post-treated by intermittent sand filter in series, wastewater treated in a septic tank and post-treated by an intermittent sand filter were tested. Irrigation was daily performed from July 2011 to January 2012 according to the water demand of cotton resulting in a water depth of 620 mm. It was found that, compared with the conventional management with freshwater irrigation, treated wastewater provides greater accumulation of micronutrient, potassium and sodium in the soil, increasing the risk of sodification in irrigated areas.

    Wong, G B

    1993-09-01

    Mandibular fractures in the pediatric patient population are relatively uncommon. These patients present with their own unique treatment requirements. Most fractures have been treated conservatively by dental splints. Closed reduction techniques with maxillomandibular fixation (MMF) in very young children can pose several concerns, including cooperation, compliance and adequate nutritional intake. Rigid internal fixation of unstable mandibular fractures using miniplates and screws circumvents the need for MMF and allows immediate jaw mobilization. At major pediatric trauma institutions, there has been an increasing trend toward the use of this treatment when open reduction is necessary. This article presents a report of a five-year-old child who presented with bilateral mandibular fractures and was treated by rigid internal fixation and immediate mandibular mobilization.

    A process is described of removing halogens or halogen compounds (or both) from the products which form when carbonaceous substances are treated thermally in the presence of halogens or halogen compounds, consisting of passing the reaction products at the same temperature with a substance able to fix halogens or acid halides through an apparatus included between the receiver and the heat exchanger, which contains, in a relatively restricted space, internal elements obliquely disposed in relation to the direction of the flow, stretched in this direction and constituted preferably of helicoidal passages.

  5. Mycoplasma genitalium: Should We Treat and How?

    Science.gov (United States)

    Broad, Jennifer M.; Golden, Matthew R.

    2011-01-01

    Mycoplasma genitalium is associated with acute and chronic urethritis in men. Existing data on infection in women are limited and inconsistent but suggest that M. genitalium is associated with urethritis, cervicitis, pelvic inflammatory disease, and possibly female infertility. Data are inconclusive regarding the role of M. genitalium in adverse pregnancy outcomes and ectopic pregnancy. Available data suggest that azithromycin is superior to doxycycline in treating M. genitalium infection. However, azithromycin-resistant infections have been reported in 3 continents, and the proportion of azithromycin-resistant M. genitalium infection is unknown. Moxifloxacin is the only drug that currently seems to uniformly eradicate M. genitalium. Detection of M. genitalium is hampered by the absence of a commercially available diagnostic test. Persons with persistent pelvic inflammatory disease or clinically significant persistent urethritis or cervicitis should be tested for M. genitalium, if possible. Infected persons who have not previously received azithromycin should receive that drug. Persons in whom azithromycin therapy fails should be treated with moxifloxicin. PMID:22080266

    Spontaneous pneumothorax is a very common medical emergency. Patients are often treated without treating the underlying cause. Lymphangioleiomyomatosis (LAM) is a rare cystic lung disease. Until recently, diagnosis of LAM was a challenge with nearly 100% mortality in 10 years, but better understanding of the disease through research and better radiological techniques and newer drugs such as sirolimus has improved the survival in such patients. We are presenting a rare case of LAM presenting as a secondary spontaneous pneumothorax treated with sirolimus. PMID:29487252

    Physicians' emotional problems need to be recognized and treated. Intervention and prevention in this problem area have been attempted at the Medical College of Wisconsin through a programme of peer counselling designed to teach student physicians how to recognize and treat emotional difficulties faced by their peers. During the 18 months that the programme has been in operation, 20 peer counsellors reported a total 1,185 hours spent in counselling their peers, lending credence to the speculation that doctors will turn to their peers for help if, in medical school, there is acceptance of fallibility and responsiveness on the part of peers.

    The transmission of pathogens, antibodies, and proteins is a possible consequence of blood product transfusion. A female patient had an unexpected positive serum β-human chorionic gonadotropin result, indicative of pregnancy, after she had received a transfusion with 1 unit of platelet concentrate, 4 units of red blood cells, and 4 units of pooled solvent/detergent-treated plasma (Octaplas). To investigate the possibility of passive transfusion of β-human chorionic gonadotropin from the plasma transfusion, one additional unit from the same batch was thawed and analyzed. To validate the β-human chorionic gonadotropin assay for use in solvent/detergent-treated plasma and to investigate any interference in the assay, dilution experiments were performed using the implicated plasma batch diluted with male and non-pregnant female sera. Also, plasma from a known pregnant woman was diluted with Octaplas (tested negative for β-human chorionic gonadotropin) and with a male serum to validate the assay for use in solvent/detergent-treated plasma. The implicated solvent/detergent-treated plasma had a mean β-human chorionic gonadotropin level of 91.5 mIU/mL. Results from the dilution experiments revealed an excellent correlation (r > 0.99) between β-human chorionic gonadotropin measurement in solvent/detergent-treated plasma and male serum and no over or under recovery of the expected results. Further measurements of β-human chorionic gonadotropin levels in the female recipient revealed an estimated half-life of 6 hours. This case demonstrates the importance of considering the possibility of passive transmission of analytes to a patient from the transfusion of blood products. Furthermore, the measurement of β-human chorionic gonadotropin is valid in solvent/detergent-treated plasma using a Roche Cobas analyzer. © 2017 AABB.

    To report on severe acid-base disturbance in a child with symptomatic epilepsy treated with sulthiame. A 9.5-year-old boy with chronic generalized tonic-clonic seizures was treated with carbamazepine and valproic acid. Because of poor seizure control, sulthiame was added to the treatment. Two months later, he presented at the emergency department with severe weakness, headache, dizziness, dyspnea, anorexia, and confusional state. Arterial blood gas analysis showed mixed respiratory alkalosis with high anion gap metabolic acidosis. Sulthiame-induced acid-base disturbance was suspected. The drug was withheld for the first 24 hours and then restarted at a reduced dosage. The arterial blood gases gradually normalized, the confusion disappeared, and the patient was discharged home.Three months later, 4 weeks after an increase in sulthiame dosage, the patient was once again admitted with the same clinical picture. Improvement was noted after the drug dosage was reduced. This is the first report of mixed respiratory alkalosis and metabolic acidosis in a child treated with sulthiame. Monitoring of the acid-base status should be considered in patients treated with sulthiame.

    Frictional coefficient 'f' was measured in the air and in water at glass-like carbon (GLC) surfaces heat-treated between 1000 and 3000 deg. C. GLCs heat-treated at higher temperature had smoother and more hydrophobic faces, and lower f. The f was smaller than 0.10 for GLCs heat-treated at and above 2000 deg. C, which indicates their applicability as a solid lubricant or a self-lubricating material. The f = 0.06 observed for GLC heat-treated at 3000 deg. C was nearly the same as that of pyrolytic graphite (PG). Slightly lower f's were obtained in water than in the air

    This study investigates the possible contribution to sustainable development by utilizing agriculture waste materials to prepare a substrate for photo-catalysis application. The photocatalytic performance of impregnated TiO2 on acid and base- treated coconut coir (CC) and their pyrolysed form have been studied. The photocatalytic performance of impregnated TiO2 on acid treated CC improved compared to bare TiO2. However, the pyrolysed samples showed higher thermal stability and porosity compared to only treated CC, their catalytic performance was decreased. It seems that impregnated TiO2 undergo interaction with treated CC during pyrolysis. More investigations to reveal exact reason of this behavior is in progress.

    Objective: To investigate the value of treating mediastinoesophageal fistula with covered stent through nasal esophagus drainage tube. Methods: Ten patients with mediastinoesophageal fistula were treated by 5F catheter inserting into the abscess cavities through nasal esophageal fistula, with stent placement in the esophagus. The abscess cavities were washed and angiograghied through drainage tube and the sites of the drainage tube were adjusted in time until withdrawal of the tube. Results: The drainage tubes were pulled out within 10-25 days with disappearance of the abscess cavities and normal diet intake without difficulty. Conclusions: Treating mediastinoesophageal fistula with covered stent through nasal esophagus drainage tube is safe, microinvasive economic and acceptable, worth to be recommended. (authors)

    Biological treatment of dye wastewater pre-treated by electron beam has been performed in order to evaluate the biodegradation and ecological stability of effluent. In the process of electron-beam treatment of wastewater there are utilized chemical transformations of pollutants induced by ionizing radiation. Partial decomposition of pollutant takes place as well as transformations of pollutant molecules that result in improving subsequent purification stages like as biological processing. Dyeing wastewater contains many kind of pollutants which are difficult to be decomposed completely by microorganisms. In this study, biodegradation with dyeing wastewater pre-treated by electron beams was observed. On the other hand, consideration on public acceptance in terms of ecological stability of biological effluent pre-treated by electron beams was given in this study. The results of laboratory investigations on biodegradation and ecological stability of effluent showed that biodegradation of dye wastewater pre-treated by electron beam was enhanced compared to unirradiated one. In the initial stage of biological oxidation regardless of different HRT, dye wastewater pre-treated by electron beam could be oxidized easily compare to without treated one. More number of survived daphnia magna could be observed in the biological effluent pre-treated by electron beam. This means that biological effluent pre-treated by electron beam can be said 'it is safe on the ecological system'

    Treating HIV-infected individuals reduces their viral load, consequently increasing their survival time and decreasing their infectivity. It has been proposed that universal testing and treatment (i.e., universal "test & treat'') could lead to HIV elimination and would be extremely cost-effective. It is now being debated whether to use a universal "test & treat'' approach in the "real-world'' as a prevention strategy to control HIV epidemics. However current modeling predictions of the impact, and cost-effectiveness, of universal `"est & treat'' strategies are based on an unrealistically short survival time for treated individuals. Here we use mathematical modeling and a longer, more realistic, survival time. We model the potential impact of a universal "test & treat'' strategy in South Africa. Our results show that increasing the length of the survival time on treatment, although beneficial to individuals, reduces the probability of eliminating HIV and decreases the cost-effectiveness of using universal "test & treat'' strategies. Therefore our results show that individual-level benefits and public health benefits will conflict when using "test &treat'' strategies to reduce HIV transmission.

    Beautiful smile is a booster to person's confidence. Gummy smile is a term used for excessive gingival display (EGD). Its etiology is multifactorial. Bone vertical maxillary excess (VME) is one of the cause of EGD. In this case series, lip repositioning was performed to treat mild to moderate degree of gingival display ( 2 to 8 mm) due to VME. Lip repositioning is simple, promising, meticulous and comparatively cheap alternative technique for treating gummy smile. (author)
