Full Text Available Abstract Background Adolescents in less developed countries such as Zambia often face multi-faceted challenges for achieving successful transitions through adolescence to early adulthood. The literature has noted the need to introduce interventions during this period, particularly for adolescent girls, with the perspective that such investments have significant economic, social and health returns to society. The Adolescent Girls Empowerment Programme (AGEP was an intervention designed as a catalyst for change for adolescent girls through themselves, to their family and community. Methods/design AGEP was a multi-sectoral intervention targeting over 10,000 vulnerable adolescent girls ages 10–19 in rural and urban areas, in four of the ten provinces of Zambia. At the core of AGEP were mentor-led, weekly girls’ group meetings of 20 to 30 adolescent girls participating over two years. Three curricula ― sexual and reproductive health and lifeskills, financial literacy, and nutrition ― guided the meetings. An engaging and participatory pedagogical approach was used. Two additional program components, a health voucher and a bank account, were offered to some girls to provide direct mechanisms to improve access to health and financial services. Embedded within AGEP was a rigorous multi-arm randomised cluster trial with randomization to different combinations of programme arms. The study was powered to assess the impact across a set of key longer-term outcomes, including early marriage and first birth, contraceptive use, educational attainment and acquisition of HIV and HSV-2. Baseline behavioural surveys and biological specimen collection were initiated in 2013. Impact was evaluated immediately after the program ended in 2015 and will be evaluated again after two additional years of follow-up in 2017. The primary analysis is intent-to-treat. Qualitative data are being collected in 2013, 2015 and 2017 to inform the programme implementation and the

Full Text Available Toxic epidermal necrolysis (TEN and Stevens Johnson Syndrome (SJS are severe adverse cutaneous drug reactions that predominantly involve the skin and mucous membranes. They are characterized by mucocutaneous tenderness and typically hemorrhagic erosions, erythema and more or less severe epidermal detachment presenting as blisters and areas of denuded skin. Drugs are assumed or identified as the main cause of SJS/TEN in most cases, but Mycoplasma pneumoniae and Herpes simplex virus infections are well documented causes alongside rare cases in which the etiology remains unknown. Several drugs are at "high" risk of inducing TEN/SJS including: Allopurinol, Trimethoprim-sulfamethoxazole and other sulfonamide-antibiotics, aminopenicillins, cephalosporins, quinolones, carbamazepine, phenytoin, phenobarbital and NSAID's of the oxicam-type. Differential diagnosis includes linear IgA dermatosis and paraneoplastic pemphigus, pemphigus vulgaris and bullous pemphigoid, acute generalized exanthematous pustulosis (AGEP, disseminated fixed bullous drug eruption and staphyloccocal scalded skin syndrome (SSSS. Due to the high risk of mortality, management of patients with SJS/TEN requires rapid diagnosis, identification and interruption of the culprit drug, specialized supportive care ideally in an intensive care unit, and consideration of immunomodulating agents such as high-dose intravenous immunoglobulin therapy.

Palmoplantar psoriasis and palmoplantar pustulosis are chronic skin diseases with a large impact on patient quality of life. They are frequently refractory to treatment, being generally described as a therapeutic challenge. This article aims to review the definitions of palmoplantar psoriasis and palmoplantar pustulosis, highlighting the similarities and differences in terms of epidemiology, clinical presentation, genetics, histopathology, and pathogenesis, as well as treatment options for both entities. Classical management of mild to moderate palmoplantar pustulosis and palmoplantar psoriasis relies on use of potent topical corticosteroids, phototherapy, and/or acitretin. Nevertheless, these drugs have proven to be insufficient in long-term control of extensive disease. Biologic therapy-namely, anti-interleukin-17 agents and phosphodiesterase type 4 inhibitors-has recently shown promising results in the treatment of palmoplantar psoriasis. Knowledge of the pathophysiologic pathways of both entities is of utmost importance and may, in the future, allow development of molecularly targeted therapeutics.

Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is an inflammatory clinical condition with aseptic bone lesions and characteristic skin manifestations. A 63-year-old woman presented with vague musculoskeletal symptoms including chronic buttock pain. The clinical work-up revealed multiple spine and osteoarticular involvement. Multilevel bone marrow edema and cortical erosions involving the spine, asymmetric sacroiliitis, and osteosclerosis of the sternoclavicular joint were consistent with a diagnosis of SAPHO syndrome. Considering SAPHO syndrome in the differential diagnosis, subsequent skin inspection revealed plantar pustulosis. Despite the unique feature of accompanying skin and skeletal lesions, skin lesions could be overlooked if not suspected

Die Pustulosis palmoplantaris ist eine chronisch entzündliche Hauterkrankung, die mit bedeutenden Einschränkungen der Lebensqualität und der Belastbarkeit einhergeht. Aufgrund von Zulassungsbeschränkungen und einem häufig therapierefraktären Verlauf sind die Behandlungsmöglichkeiten limitiert. Nach zuvor frustranen Therapien erhielten 9 Patienten mit Pustulosis palmoplantaris nach Ausschluss einer latenten Tuberkulose Ustekinumab (45 mg Ustekinumab bei  100 kg KG) in Woche 0, 4, 12 und 24. Reguläre Visiten erfolgten nach 4 und 12 Wochen, im weiteren Verlauf alle 12 Wochen. Das Durchschnittsalter bei Therapiebeginn betrug 48 Jahre. Drei Patienten waren männlich. Bei n  =  4 Patienten (44,4 %) wurde eine Verbesserung um 75 % des Palmoplantar-Psoriasis-Area-Severity-Index (PPPASI) erreicht. Insgesamt verbesserte sich der PPPASI nach 24 Wochen durchschnittlich um 71,6 %. Eine komplette Abheilung zeigte sich bei n  =  2 Patienten nach 24 Wochen. Bis auf lokale Injektionsreaktionen und leichte Infekte wurden keine unerwünschten Wirkungen beobachtet. Die Fallserie ist ein weiterer Beleg für die Wirksamkeit und Verträglichkeit von Ustekinumab in der Therapie der Pustulosis palmoplantaris. Zur Beurteilung der Langzeitwirkung und -sicherheit sowie der Wirksamkeit einer intermittierenden Therapie sind kontrollierte Studiendaten sowie Beobachtungen im Rahmen von Patientenregistern notwendig. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

2012-01-01

There is a spectrum of musculoskeletal disorders which can be associated with dermatologic findings, the fundamental component of which is a nonbacterial osteitis. CRMO (Chronic recurrent multifocal osteomyelitis) and SAPHO syndrome (Synovitis, Acne, Pustulosis, Hyperostosis and Osteitis) describe paediatric and adult conditions, respectively, of inflammatory osteitis that can be associated with palmoplantar pustulosis and acne. Imaging findings are similar and a key component to the diagnosis in both conditions. This report describes two patients with strikingly similar radiologic presentations of clavicular osteitis in whom the diagnosis was made predominantly on the basis of imaging findings. The typical imaging features and radiographic hallmarks of both conditions will also be discussed.

Full Text Available As reações cutâneas graves adversas à droga são as que geralmente necessitam de internação hospitalar, por vezes em unidade de terapia intensiva ou de queimados, com observação minuciosa dos sinais vitais e da função de órgãos internos. O objetivo é descrever estas reações facilitando o seu reconhecimento e tratamento. Fazem parte deste grupo a Síndrome de Hipersensibilidade à Droga (SHD, a Pustulose Exantemática Generalizada Aguda (PEGA, a Necrose Cutânea induzida por Anticoagulante, as Vasculites de Pequenos Vasos (VPV, a Vasculite de Hipersensibilidade ao Propiltiouracil (VHP e as Reações tipo Doença do Soro (RDS. A SHD tem-se tornado de elevada relevância clínica devido ao uso amplo dos anticonvulsivantes aromáticos e da dapsona, utilizada no tratamento de doenças como a acne e a hanseníase. A PEGA é determinada principalmente pelos derivados beta-lactâmicos e tem como principal diagnóstico diferencial a psoríase pustulosa generalizada. As VPV tegumentares podem refletir uma doença multissistêmica subjacente, com danos graves em órgãos nobres, como os rins, pulmões e sistema hematológico, com morbidade elevada e possível letalidade.

IL-8 is a chemokine that has been implicated in a number of inflammatory diseases involving neutrophil activation. HuMab 10F8 is a novel fully human mAb against IL-8, which binds a discontinuous epitope on IL-8 overlapping the receptor binding site, and which effectively neutralizes IL-8-dependent...... human neutrophil activation and migration. We investigated whether interference in the cytokine network by HuMab 10F8 might benefit patients suffering from palmoplantar pustulosis, a chronic inflammatory skin disease. Treatment of patients with HuMab 10F8 was well tolerated and significantly reduced...... clinical disease activity at all five endpoints, which included a >= 50% reduction in the formation of fresh pustules. IL-8 neutralization was monitored at the site of inflammation by assessing exudates of palmoplantar pustulosis lesions. HuMab 10F8 sequestered IL-8 in situ, as observed by rapid dose...

Objective: To describe the clinical and imaging manifestations of patients with synovitis acne pustulosis hyperostosis osteomyelitis (SAPHO) syndrome, and to analyze the diagnostic importance of different clinical and imaging manifestations for SAPHO syndrome. Methods: Seventeen patients (7 males and 10 females) with SAPHO syndrome were recruited in this study. Age ranged from 36 to 67 years with a mean age of (48 ± 8) years. All patients fulfilled the diagnostic criteria of Benhamou. Serum HLA B27 antigen records were reviewed for all patients. Imaging data of the abnormal bone sites were collected by conventional radiograph in all patients, CT in 13 patients as well as MR in 3 patients. Average time to take for a definite diagnosis of the syndrome was 3.7 years (ranged from O.5 to 13 years). Results: Serum HLA B27 antigen was positive in all patients. Both skin and bone abnormalities were found in all patients. Ten patients had skin palmoplantar pustulosis and two patients had acne. Involving sites of bone and joints include sacroiliac joints, anterior chest and limbs. Sacroiliac joints were asymmetrically involved with imaging features in all patients. Eight patients exhibited anterior chest wall involvement. Five patients had osteomyelitis at limbs. For all images of 17 patients, CT was superior to conventional radiography in detecting abnormal changes of bone erosion and soft tissue swelling. MR imaging was able to depict edema changes that was not detectable by CT and radiography. Conclusion: SAPHO syndrome is a rare disease, but for patients with skin and bone-joint abnormalities, especially with skin palmoplantar pustulosis, acne as well as with imaging features at the sacroiliac joint and anterior chest wall, SAPHO syndrome should be taken into a diagnostic consideration.

Sorafenib is a multi-targeted kinase inhibitor, which is the current standard treatment for advanced hepatocellular carcinoma (HCC). Only one case of radiation recall dermatitis (RRD) associated with sorafenib has been reported so far. Our patient with recurrent HCC was treated with palliative radiotherapy (RT) for the chest wall mass. Sorafenib at 400 mg twice daily was begun on the day following RT. On the 14th day post-RT, an erythematous patch was observed on right chest wall which matched area previously irradiated. It was consistent with RRD. Ten days later, a disseminated exanthematous rash and severe pruritus occurred. Sorafenib was stopped and an oral antihistamine was prescribed to relieve symptoms. At the 1-week follow-up after the cessation of sorafenib, all symptoms were resolved. Physicians should be alert to this recall phenomenon as it can occur both in the skin and elsewhere and the occurrence of RRD may be unpredictable.

beta-lactam antibiotics are the agents most frequently implied in immune drug adverse reactions. These can be classified as immediate or nonimmediate according to the time interval between the last drug administration and their onset. Mechanisms of immediate IgE-mediated reactions are widely studied and are therefore better understood. Nonimmediate reactions include a broad number of clinical entities like mild maculopapular exanthemas, the most common, and other less frequent but more severe reactions such as Stevens-Johnson syndrome, toxic epidermal necrolysis, acute exanthematic pustulosis or cytopenias. These nonimmediate reactions are mainly mediated by T cells but the precise underlying mechanisms are not well elucidated. This fact complicates the allergological evaluation of patients with this type of reaction and available tests have demonstrated poor sensitivity and specificity.

Speech production accuracy and variability in young cochlear implant recipients: comparisons with typically developing age-peers.

Ertmer, David J; Goffman, Lisa

2011-02-01

The speech production accuracy and variability scores of 6 young cochlear implant (CI) recipients with 2 years of device experience were compared with those of typically developing (TD) age-peers. Words from the First Words Speech Test (FWST; Ertmer, 1999) were imitated 3 times to assess the accuracy and variability of initial consonants, vowels, and words. The initial consonants in the 4 sets of the FWST followed a typical order of development. The TD group produced targets with high accuracy and low variability. Their scores across FWST sets reflected the expected order of development. The CI group produced most targets less accurately and with more variability than the TD children. Relatively high accuracy for the consonants of Sets 1 and 2 indicated that these phonemes were acquired early and in a typical developmental order. A trend toward greater accuracy for Set 4 as compared with Set 3 suggested that later-emerging consonants were not acquired in the expected order. Variability was greatest for later-emerging initial consonants and whole words. Although considerable speech production proficiency was evident, age-level performance was not attained after 2 years of CI experience. Factors that might influence the order of consonant acquisition are discussed.

Full Text Available Abstract Toxic epidermal necrolysis (TEN and Stevens Johnson Syndrome (SJS are severe adverse cutaneous drug reactions that predominantly involve the skin and mucous membranes. Both are rare, with TEN and SJS affecting approximately 1or 2/1,000,000 annually, and are considered medical emergencies as they are potentially fatal. They are characterized by mucocutaneous tenderness and typically hemorrhagic erosions, erythema and more or less severe epidermal detachment presenting as blisters and areas of denuded skin. Currently, TEN and SJS are considered to be two ends of a spectrum of severe epidermolytic adverse cutaneous drug reactions, differing only by their extent of skin detachment. Drugs are assumed or identified as the main cause of SJS/TEN in most cases, but Mycoplasma pneumoniae and Herpes simplex virus infections are well documented causes alongside rare cases in which the aetiology remains unknown. Several drugs are at "high" risk of inducing TEN/SJS including: Allopurinol, Trimethoprim-sulfamethoxazole and other sulfonamide-antibiotics, aminopenicillins, cephalosporins, quinolones, carbamazepine, phenytoin, phenobarbital and NSAID's of the oxicam-type. Genetic susceptibility to SJS and TEN is likely as exemplified by the strong association observed in Han Chinese between a genetic marker, the human leukocyte antigen HLA-B*1502, and SJS induced by carbamazepine. Diagnosis relies mainly on clinical signs together with the histological analysis of a skin biopsy showing typical full-thickness epidermal necrolysis due to extensive keratinocyte apoptosis. Differential diagnosis includes linear IgA dermatosis and paraneoplastic pemphigus, pemphigus vulgaris and bullous pemphigoid, acute generalized exanthematous pustulosis (AGEP, disseminated fixed bullous drug eruption and staphyloccocal scalded skin syndrome (SSSS. Due to the high risk of mortality, management of patients with SJS/TEN requires rapid diagnosis, evaluation of the prognosis

Pustulosis palmaris et plantaris (PPP) is a chronic, inflammatory, autoimmune-type disease characterized by sterile pustules of skin. The skin inflammation is influenced by several factors such as drugs, sunlight, metabolic and psychogenic factors as well as metal allergy. Here, we report a rare case that intensive periodontal treatment might have contributed to the improvement of skin inflammation. Skin inflammation regressed 1 month after intensive periodontal treatment. Both CD4/CD8 ratio and % of B cells in the blood sample were slightly decreased corresponding to the improvement of periodontal inflammation. Infection control of periodontal lesions might be one of attractive therapeutic targets in management of PPP.

Full Text Available The efficacy of using fasting plasma glucose (FPG alone as a preferred screening test for diabetes has been questioned. This study was aimed to evaluate whether the use of serum advanced glycation end products-peptides (sAGEP would help to improve the efficacy of FPG in diabetes screening among high-risk Chinese subjects with FPG <7.0 mmol/L. FPG, 2-h plasma glucose (2h-PG, serum glycated haemoglobin A1c (HbA1c, and sAGEP were measured in 857 Chinese subjects with risk factors for diabetes. The areas under receiver operating characteristic (ROC curves generated by logistic regression models were assessed and compared to find the best model for diabetes screening in subjects with FPG <7.0 mmol/L. The optimal critical line was determined by maximizing the sum of sensitivity and specificity. Among the enrolled subjects, 730 of them had FPG <7.0 mmol/L, and only 41.7% new diabetes cases were identified using the 1999 World Health Organization FPG criterion (FPG ≥7.0 mmol/L. The area under ROC curves generated by the model on FPG-sAGEP was the largest compared with that on FPG-HbA1c, sAGEP, HbA1c or FPG in subjects with FPG <7.0 mmol/L. By maximizing the sum of sensitivity and specificity, the optimal critical line was determined as 0.69×FPG + 0.14×sAGEP = 7.03, giving a critical sensitivity of 91.2% in detecting 2h-PG ≥11.1 mmol/L, which was significantly higher than that of FPG-HbA1c or HbA1c. The model on FPG-sAGEP improves the efficacy of using FPG alone in detecting diabetes among high-risk Chinese subjects with FPG <7.0 mmol/L, and is worth being promoted for future diabetes screening.

Based on Molecular Profiling of Gene Expression, Palmoplantar Pustulosis and Palmoplantar Pustular Psoriasis Are Highly Related Diseases that Appear to Be Distinct from Psoriasis Vulgaris.

Directory of Open Access Journals (Sweden)

Robert Bissonnette

Full Text Available There is a controversy surrounding the existence of palmoplantar pustulosis (PPP and palmoplantar pustular psoriasis (PPPP as separate clinical entities or as variants of the same clinical entity. We used gene expression microarray to compare gene expression in PPP and PPPP.Skin biopsies from subjects with PPP (3, PPPP (6, psoriasis vulgaris (10 and acral skin from normal subjects (7 were analyzed using gene expression microarray. Principal component analysis showed that PPP and PPPP were different from psoriasis vulgaris and normal acral skin. However gene expression of PPP and PPPP clustered together and could not be used to differentiate PPP from PPPP. Gene-wise comparison between PPP and PPPP found no gene to be differentially expressed at a false discovery rate lower than 0.05. Surprisingly we found a higher expression of several genes involved in neural pathways (e.g. GPRIN and ADAM23 in PPP/PPPP as compared to psoriasis vulgaris and normal acral skin. Immunohistochemistry confirmed those findings and showed a keratinocyte localization for those proteins.PPP and PPPP could not be differentiated using gene expression microarray suggesting that they are not distinct clinical entities. Increased expression of GPRIN1, and ADAM23 in keratinocytes suggests that these proteins could be new therapeutic targets for PPP/PPPP.

Interleukin (IL)-8 and IL-36γ but not IL-36Ra are related to acrosyringia in pustule formation associated with palmoplantar pustulosis.

Palmoplantar pustulosis (PPP) is a refractory, nonbacterial impetigo confined to the palms and soles. Its pathogenesis is still obscure, but it may be associated with the large eccrine sweat glands and pores of palmoplantar skin. PPP is considered to be a localized pustular psoriasis. Interleukin (IL)-8, IL-36γ and IL-36Ra play important roles in the pathogenesis of pustular psoriasis, but their role in PPP is unclear. To evaluate IL-8, IL-36γ and IL-36Ra expression in PPP, and their relationship with acrosyringia and pustule formation. mRNA expression was quantified in skin samples from patients with PPP (n = 7), patients with psoriasis vulgaris (PSV; n = 8) and healthy controls (HCs) (n = 6) by reverse-transcription-real-time PCR. Protein expression was characterized by immunohistochemistry (PPP, n = 17; PSV, n = 14; HCs, n = 12). Sweat ducts, including acrosyringia, were stained for epithelial membrane antigen (EMA). IL-8 mRNA and protein were markedly increased in PPP lesions compared with PSV lesions or HC skin. IL-36γ mRNA and protein were significantly more abundant in PPP lesions than in HC skin. IL-36Ra mRNA was significantly overexpressed in PPP lesions compared with HC skin, but there was no difference in IL-36Ra protein between PPP, PSV and HCs. IL-8 was abundantly expressed by neutrophils in PPP pustules, while IL36Ra was localized in the keratinocytes of PPP, PSV and HC skin. IL-36γ and EMA were colocalized in cells surrounding PPP pustules, and IL-36γ was also expressed in sweat duct cells in the dermis. IL-8, IL-36γ and IL-36Ra are overexpressed in PPP lesions. IL-8, IL-36γ and acrosyringia, rather than IL-36Ra, are associated with pustule formation in PPP. © 2018 British Association of Dermatologists.

Bone scintigraphy with sup(99m)Tc-methylene diphosphonate (MDP) was performed in 38 patients with psoriasis, 5 patients with palmoplantar pustulosis, and 56 control subjects. Abnormal uptake was seen primarily in the sternoclavicular junction and the cartilage of the first rib in 24 of the patients with psoriasis (63%) and in 3 of the patients with palmoplantar pustulosis (60%), and in the sternoclavicular junction in 21 of the control subjects (38%). The incidence of uptake in the sternoclavicular junction area in the psoriasis patients clearly exceeded that in the control subjects. (Namekawa, K.)

The synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome includes a group of chronic, relapsing, inflammatory musculoskeletal disorders with similar manifestations, in particular synovitis, hyperostosis, and osteitis, which may or may not be associated with neutrophilic skin eruptions such as palmoplantar pustulosis and acne conglobata. The syndrome occurs at any age, can involve any skeletal site, and its imaging appearances are variable, depending on the stage/age of the lesion and imaging method. The diagnosis is difficult if there is no skin disease. Awareness of the imaging appearances, especially in the spine, may help the radiologist in avoiding misdiagnosis (e.g., infection, tumor) and unnecessary invasive procedures, while facilitating early diagnosis and selection of an effective treatment. In this article, we provide an overview of the radiological appearances of SAPHO syndrome, focusing on the magnetic resonance imaging findings of vertebral involvement, and present relevant clinical and pathological features that assist early diagnosis.

The objective of our study was to clarify the radiologic spectrum of disease entities belonging to the SAPHO syndrome (SAPHO being an acronym for synovitis, acne, pustulosis, hyperostosis, and osteitis). A retrospective analysis of radiologic data was undertaken to determine the relationship of the osteoarthritic changes seen in palmoplantar pustulosis (PPP, n = 179), acne (n = 3), psoriasis vulgaris (PsV, n = 355), generalized pustular psoriasis (GPP, n = 25), and chronic recurrent multifocal osteomyelitis (CRMO, n = 4). Osseous changes of PPP, acne, and CRMO overlap each other; 7 PPP, 2 acne, and 3 CRMO patients manifested stenocostoclavicular hyperostosis as well as hyperostosis of the spine, pelvis, and/or femur. These findings were not seen in either PsV or GPP patients. Thirteen PsV and 4 GPP patients had peripheral arthritis and/or symmetrical sacroiliitis, which were not observed in the PPP, acne, and CRMO patients. The PPP, acne, and CRMO patients may be grouped as belonging to the single disease entity, namely SAPHO syndrome. Our findings do not support the inclusion of PsV and GPP in the spectrum of this syndrome. (orig.)

Full Text Available Gianotti-Crosti syndrome is parainfectious exanthematous disease having unique presentation of small papulovesicular eruptions symmetrically over extensor surface of limbs and face in children. Hemorrhagic lesions are very rare and are always localized. Here, a case of EBV-induced Gianotti-Crosti syndrome with extensive hemorrhagic vesicles in a one and half month old infant, possibly induced by Epstein Barr virus, is reported. Neither the involvement of the disease at this early age nor the extensive hemorrhagic vesicles as the predominant presentation is reported before.

We have studied retrospectively a series of 10 children presenting with chronic multifocal osteomyelitis (8 girls, 2 boys, 7 to 16 years). All patients had plain films, bone scintigraphies and histological studies. Three had CT scan and/or MRI. Compared with literature data, we observed only one case of palmo-plantar pustulosis and only 2 cases of lysis of the medial extremity of the clavicle; in addition, we report one case of lateral extremity of the clavicle and 2 vertebral locations. The radiological pattern was typical: at the beginning of the disease, plain films showed lytic areas which became progressively osteosclerotic with enlargement of the bone. In all the cases, bone scintigraphy revealed high uptake areas which were often infra-clinical. The diagnosis was delayed from 3 months to 3 years. This emphasizes the difficulty of the diagnosis which relies on the association of clinical, biological and radiological elements. Biopsies are required to rule out an infectious bacterial osteomyelitis or a tumoral process. The pathogenesis of OCMR remains unknown, but the relation with the SAPHO (synovitis, acne, pustulosis, Hyperostosis, osteitis) syndrome is general accepted because of the similar features of the osteitis. The long term follow up appears to be uncertain: 6 of our patients are still symptomatic after five years despite anti inflammatory treatment. (authors). 22 refs.

SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) is an umbrella acronym for inflammatory clinical conditions whose common denominator is aseptic osteoarticular involvement with characteristic skin lesions. It involves all ages, can involve any skeletal site, and has variable imaging appearances depending on the stage/age of the lesion and imaging method. It mimics important differentials including infection and neoplasia. Awareness of the imaging features, especially in the spine, facilitates early diagnosis, prevents repeated biopsies, and avoids unnecessary surgery, while initiating appropriate treatment.

Full Text Available Dengue virus (DENV and parvovirus B19 (B19V infections are acute exanthematic febrile illnesses that are not easily differentiated on clinical grounds and affect the paediatric population. Patients with these acute exanthematic diseases were studied. Fever was more frequent in DENV than in B19V-infected patients. Arthritis/arthralgias with DENV infection were shown to be significantly more frequent in adults than in children. The circulating levels of interleukin (IL-1 receptor antagonist (Ra, CXCL10/inducible protein-10 (IP-10, CCL4/macrophage inflammatory protein-1 beta and CCL2/monocyte chemotactic protein-1 (MCP-1 were determined by multiplex immunoassay in serum samples obtained from B19V (37 and DENV-infected (36 patients and from healthy individuals (7. Forward stepwise logistic regression analysis revealed that circulating CXCL10/IP-10 tends to be associated with DENV infection and that IL-1Ra was significantly associated with DENV infection. Similar analysis showed that circulating CCL2/MCP-1 tends to be associated with B19V infection. In dengue fever, increased circulating IL-1Ra may exert antipyretic actions in an effort to counteract the already increased concentrations of IL-1β, while CXCL10/IP-10 was confirmed as a strong pro-inflammatory marker. Recruitment of monocytes/macrophages and upregulation of the humoral immune response by CCL2/MCP-1 by B19V may be involved in the persistence of the infection. Children with B19V or DENV infections had levels of these cytokines similar to those of adult patients.

Vertebral osteomyelitis without disc involvement

Energy Technology Data Exchange (ETDEWEB)

Kamani, I.; Syed, I.; Saifuddin, A. E-mail: asaifuddin@aol.com; Green, R.; MacSweeney, F

2004-10-01

Vertebral osteomyelitis is most commonly due to pyogenic or granulomatous infection and typically results in the combined involvement of the intervertebral disc and adjacent vertebral bodies. Non-infective causes include the related conditions of chronic recurrent multifocal osteomyelitis (CRMO) and SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndrome. Occasionally, these conditions may present purely within the vertebral body, resulting in various combinations of vertebral marrow oedema and sclerosis, destructive lesions of the vertebral body and pathological vertebral collapse, thus mimicking neoplastic disease. This review illustrates the imaging features of vertebral osteomyelitis without disc involvement, with emphasis on magnetic resonance imaging (MRI) findings.

Full Text Available A total of 730 children aged less than 7 years, attending 8 day-care centers (DCCs in Belém, Brazil were followed-up from January to December 1997 to investigate the occurrence of human-herpes virus 6 (HHV-6 infection in these institutional settings. Between October and December 1997 there have been outbreaks of a febrile- and -exanthematous disease, affecting at least 15-20% of children in each of the DCCs. Both serum- and- plasma samples were obtained from 401 (55% of the 730 participating children for the detection of HHV-6 antibodies by enzyme-linked immunosorbent assay (ELISA, and viral DNA amplification through the nested-PCR. Recent HHV-6 infection was diagnosed in 63.8% (256/401 of them, as defined by the presence of both IgM and IgG-specific antibodies (IgM+/IgG+; of these, 114 (44.5% were symptomatic and 142 (55.5% had no symptoms (p = 0.03. A subgroup of 123 (30.7% children were found to be IgM-/IgG+, whereas the remaining 22 (5.5% children had neither IgM nor IgG HHV-6- antibodies (IgM-/IgG-. Of the 118 children reacting strongly IgM-positive ( > or = 30 PANBIO units, 26 (22.0% were found to harbour the HHV-6 DNA, as demonstrated by nested-PCR. Taken the ELISA-IgM- and- nested PCR-positive results together, HHV-6 infection was shown to have occurred in 5 of the 8 DCCs under follow-up. Serological evidence of recent infections by Epstein-Barr virus (EBV and parvovirus B19 were identified in 2.0% (8/401 and 1.5% (6/401 of the children, respectively. Our data provide strong evidence that HHV-6 is a common cause of outbreaks of febrile/exanthematous diseases among children attending DCCs in the Belém area.

To describe the age, signs and clinical symptoms of children with scarlet fever at the present time, and to check whether they are equivalent to those with traditional streptococcal pharyngotonsillitis. An observational, retrospective study was conducted on the clinical records of 5500 children aged from 0 to 15 years attending a primary health care center. A record was made of the percentage of the cases in which signs and symptoms appear and the Centor score was calculated. Microbiological diagnosis of the disease was made using the rapid antigen-detection test or traditional culture. A total of 171 out of 252 scarlet fever diagnoses were microbiologically verified in 158 patients. The median age was 3.8 years (interquartile range: 2.91-4.78), with the majority (57%) under the age of 4 years. There was fever in 89% of the processes (95% CI: 84-94%), with a temperature of >38°C in 73% (95% CI: 65-80%), enlarged lymph nodes in 70% (95% CI: 58-82%), absence of cough in 73% (95% CI: 65-80%), and tonsillar exudate in only 24% (95% CI: 17-31%). The Centor score (n=105) was ≤2 points in 86% (95% CI: 79-92%). The only difference regarding age is that episodes in patients under the age of 4 years old have significantly higher fever (>38°C) than the older ones (80% versus 63%. OR 3.13; 95% CI: 1.46-6.71). Scarlet fever pharyngotonsillitis differs from the traditional streptococcal pharyngotonsillitis, and its evaluation using clinical prediction rules such as Centor or McIsaac is questionable. The main diagnostic key must certainly be rash, regardless of patient age. Copyright © 2015 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

An Infant With Transient Neonatal Pustular Melanosis Presenting as Pustules

Directory of Open Access Journals (Sweden)

Pei-San Chia

2010-12-01

Full Text Available Transient neonatal pustular melanosis is mostly found in full-term black infants. It is a benign and self-limited disease, and the etiology is still unknown. We present a full-term female neonate with multiple vesiculopustular and pigmented macular lesions found immediately after her birth. A skin biopsy showed vesicles consisting of intracorneal and subcorneal aggregates of neutrophils, which is compatible with transient neonatal pustular melanosis. Although it is rare in Taiwan and Asian countries, transient neonatal pustular melanosis should always be considered when pustulosis is found in the neonatal period to prevent the use of unnecessary antibiotics. Dermatological consultation and histological confirmation are sometimes required for the final diagnosis.

Colombian physician Luis Benigno Patiño Camargo was one of the pioneers in the study of rickettsioses in South America, demonstrating for the first time in Colombia the presence of Rickettsia rickettsii as the etiological agent of a highly deadly exanthematic febrile syndrome in the 1930s. However, Patiño-Camargo performed other investigations from 1917-1943, which represent the first descriptions and scientific evidence of the presence of R. prowazekii and R. typhi in Colombia. Almost 60 years after the latest research conducted by Dr. Patiño-Camargo, rickettsioses were again a matter of interest and research. In the last decade over 20 research studies have been published, showing new endemic areas for R. rickettsii, as well as the description of new rickettsial species in Colombia. PMID:27074327

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...

2018-03-30

Hyper-immunoglobulin D syndrome is a rare autosomal-recessive autoinflammatory syndrome in which a mevalonate kinase deficiency results due to mutations of the mevalonate kinase gene. We report a case of an Asian male infant who was found to have hyper-immunoglobulin D syndrome in the absence of fever. His skin manifestations included cephalic pustulosis as well recurrent transient and fixed pink plaques and nodules on the face and extremities. Subsequent examination revealed hyper-immunoglobulin D syndrome with two novel allelic mutations in the mevalonate kinase gene: c.895G > A (p.D299N) and c.1168C > T (p.Q390). It is important for dermatologists to recognize the varied cutaneous presentations of hyper-immunoglobulin D syndrome because rapid diagnosis and treatment can significantly affect outcomes. © 2018 Wiley Periodicals, Inc.

SAPHO: syndrome or concept? Imaging findings

The SAPHO syndrome was a term coined to include a variety of musculoskeletal disorders associated with skin conditions, mainly palmoplantar pustulosis and acne conglobata. It is more correctly a spectrum which includes the following: skin lesions, osteoarticular manifestations of synovitis hyperostosis and osteitis affecting particular target sites, and.a clinical course marked by relapses and remissions. The major sites of involvement are the anterior chest wall, the spine, long bones, flat bones, and large and small joints. The distribution and severity of involvement varies from the adult to the pediatric form of chronic recurrent multifocal osteomyelitis (CRMO). The diagnosis of SAPHO syndrome is not difficult when the typical osteoarticular lesions are located in characteristic target sites. The diagnosis is more difficult if atypical sites are involved and there is no skin disease. (orig.)

One patient was a 71-year-old man who had been treated with radiation therapy mainly using grenz rays for 8 years since 1976 for pustulosis on the bilateral planta pedis. The other was a 47-year-old woman who had received it for 3 months during summer time for 5 years since 1973. In both patients, histological examination of the epidermis showed actinic keratosis (AK)-like lesions, presumabley being bowenoid type. Malignant transformation of chronic radiation dermatitis is considered attributable to lesions analogous to AK, and AK lesions are frequently associated with Bowen's disease arising in chronic radiation dermatitis. Thus AK-like lesions of bowenoid type, as seen in these two patients, seems to be sometimes confused with Bowen's disease attributable to chronic radiation dermatitis. (N.K.).

SAPHO syndrome-acronym for synovitis, acne, pustules, hyperostosis and osteitis, is a nosological entity including multiple affections with cutaneous and osteoarticular involvement. We report the case of a 59 years old female patient that consulted due to an acute sternal pain. After some months the patient showed a palm-plantar pustular exanthem, acne and fever. SAPHO syndrome was diagnosed based on a CT, an osseous gammagraphy and a biopsy of cutaneous lesions. The current actual tendency is to consider the SAPHO syndrome as a seronegative arthropathy with a similar pathophysiology to Reiter's syndrome. (author)

Syndromic classification of rickettsioses: an approach for clinical practice

Full Text Available Rickettsioses share common clinical manifestations, such as fever, malaise, exanthema, the presence or absence of an inoculation eschar, and lymphadenopathy. Some of these manifestations can be suggestive of certain species of Rickettsia infection. Nevertheless none of these manifestations are pathognomonic, and direct diagnostic methods to confirm the involved species are always required. A syndrome is a set of signs and symptoms that characterizes a disease with many etiologies or causes. This situation is applicable to rickettsioses, where different species can cause similar clinical presentations. We propose a syndromic classification for these diseases: exanthematic rickettsiosis syndrome with a low probability of inoculation eschar and rickettsiosis syndrome with a probability of inoculation eschar and their variants. In doing so, we take into account the clinical manifestations, the geographic origin, and the possible vector involved, in order to provide a guide for physicians of the most probable etiological agent.

The skin in psoriasis: assessment and challenges.

Science.gov (United States)

Oji, Vinzenz; Luger, Thomas A

2015-01-01

The coexistence of psoriasis arthritis (PsA) and psoriasis vulgaris in about 20% of patients with psoriasis leads to a need for rheumatologic-dermatologic team work. We summarise the role of dermatologists in assessment of the skin in psoriasis. Chronic plaque psoriasis must be differentiated from other subtypes such as generalised pustular psoriasis (GPP) or palmoplantar pustulosis (PPP). Therapeutic management is based on the evaluation of the disease severity. Quantitative scoring of skin severity includes calculation of the Psoriasis Area and Severity Index (PASI), body surface area (BSA) as well as the Dermatology Life Quality Index (DLQI). These scoring systems do not replace the traditional dermatologic medical history and physical examination of the patient. The skin should be examined for additional skin diseases; moreover, patients should be monitored for comorbidity, most importantly PsA and cardiovascular comorbidity.

Full Text Available A retrospective serologic study was carried out in Fortaleza, State of Ceará, Brazil, in order to detect the dengue virus activity before recognizing the epidemic of 1994. Mac-Elisa was performed by using a mixture of specific DEN-1 and DEN-2 antigens on serum samples from the Emilio Ribas Laboratory collection. Samples were obtained from 1,224 patients with exanthematic febrile disease and negative serological results for rubella. All specimens were taken during November 1993 to May 1994. The results confirmed dengue infections in Fortaleza by November 1993, approximately six months before the beginning of the epidemic, proving how misleading diagnosis of dengue infection are still troublesome, in spite of the strong dengue activity in Ceará. The authors stress the urgent necessity to implement the active surveillance system in order to prevent another extensive dengue fever epidemics in the state. Epidemiological background of the dengue activity in the State of Ceará is also described.

Full Text Available Neonatal pustular eruption is a group of disorders characterized by various forms of pustulosis seen in first 4 weeks of life. Its presentation is often similar with some subtle differences, which can be further established by few simple laboratory aids, to arrive at a definite diagnosis. Given their ubiquitous presentation, it is sometimes difficult to differentiate among self-limiting, noninfectious, pustular dermatosis such as erythema toxicum neonatorum, transient neonatal pustular melanosis, miliaria pustulosa, etc., and potentially life threatening infections such as herpes simplex virus and varicella zoster virus infections. This review article tries to address the chronological, clinical, morphological, and histological differences among the various pustular eruptions in a newborn, in order to make it easier for a practicing dermatologist to diagnose and treat these similar looking but different entities of pustulation with a clear demarcation between the physiological benign pustular rashes and the infectious pustular lesions.

Chronic recurrent multifocal osteomyelitis is a rare disorder that affects children and teenagers. Clinically, it is characterized by insidious onset of local swelling and pain in several metaphyses. A symmetric, recurrent and multifocal pattern is usual. Spinal involvement is possible. Inconstant association with a cutaneous affection (palmo-plantar pustulosis, acne fulminans, psoriasis), or less frequently with an inflammatory chronic gut disorder is described. Pathogenesis usually recognized is an enthesopathy. Enthesitis may progress to the osseous part of the enthese and produce an aseptic chronic osteomyelitis. Biopsy specimen with culture is certainly necessary to rule out bacterial osteomyelitis and bone tumor. It is particularly true when the bone lesion is isolated. Disease course is benign and self-limited. The clinical course is characterized by recurrences and remissions occurring for 6 to 10 years. Treatment based on non steroid anti-inflammatory drugs is usually effective. (authors). 17 refs.

308nm xenon-chloride excimer laser, a novel mode of phototherapy, is an ultraviolet B radiation system consisting of a noble gas and halide. The aim of this systematic review was to investigate the literature and summarize all the experiments, clinical trials and case reports on 308-nm excimer laser in dermatological disorders. 308-nm excimer laser has currently a verified efficacy in treating skin conditions such as vitiligo, psoriasis, atopic dermatitis, alopecia areata, allergic rhinitis, folliculitis, granuloma annulare, lichen planus, mycosis fungoides, palmoplantar pustulosis, pityriasis alba, CD30+ lympho proliferative disorder, leukoderma, prurigo nodularis, localized scleroderma and genital lichen sclerosus. Although the 308-nm excimer laser appears to act as a promising treatment modality in dermatology, further large-scale studies should be undertaken in order to fully affirm its safety profile considering the potential risk, however minimal, of malignancy, it may impose.

Ruth Rien Gutfeund on the finding of Rickettsia Prowazeki in domestic animals in Ethiopia and their transmission by ticks, saying that this confirms his own ideas, expressed long ago, that there is not, in the exanthematic typhus group, usually, strict specificness for the carries, therefore this feature cannot serve as a basis for rational classification. He describes a clinic case, showing the difficulty of a diagnosis confounded with typhoid fever, even after long experience in examining the disease and that only an inoculation in sensitive animals - here guiena-pigs - can decide the question. He next studies two epidemical outbreaks of neotropic exanthematic typhus - in 1950 in Carmópolis (Minas Gerais; another in 1956 in Mucuri (Bahia. In both the percentage of deaths, in the serous cases, that had no treatment, was high and the therapeutics by the antibiotics, principally Cloromicetina and Terramycina was brilliant.

Synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) is a syndrome that combines dermatological, articular and osseous inflammatory manifestations. Bilateral laryngeal immobility relative to cricoarytenoid joint origin is very uncommon. This article presents a case of bilateral cricoarytenoid joint ankylosis in a SAPHO syndrome context. A 53-year-old patient presenting with a two year history of intermittent bouts of dyspnea. A SAPHO syndrome was discussed on repeated thoracic CT-scan. The link between dyspnea and SAPHO syndrome had not been made immediately given the absence of any known anteriority. However, having ruled out other etiologies and after having had to perform a tracheotomy due a worsening of the respiratory condition, this diagnosis was considered. Treatment by corticosteroids and infliximab permitted a clinical improvement of the patient. This clinical case report should increase awareness of possible cricoarytenoid joint involvement in SAPHO.

A case of sternocostoclavicular hyperostosis (SCCH) with a duration of 15 years and initially associated with palmoplantar pustulosis (PPP) and then with typical psoriasis has been presented. Signs of inflammation were persistent, but the pain in the involved areas was not severe. In addition to classical radiological signs of SCCH (bilateral remodelling of the clavicles and the upper ribs with unhealed fractures and ossification of the costoclavicular ligament), peripheral involvement was observed in the form of segmental remodelling of the right humerus and tibia. Biopsy specimens of ribs and bone around affected joints showed a range of changes consisting of superficial remodelling of bone, acute or chronic inflammatory foci and subperiosteal formation of bone. The data indicate that involvement in the upper portion of the chest in SCCH can be a part of a more diffuse pathological process. The possible role of an infective origin (in spite of the absence of organisms on culture), possibly associated with immunological disturbances, is discussed. (orig.)

SAPHO (synovitis, acne, pustulosis, hyperostosis and osteitis) syndrome is a cluster of osteo-cutaneous manifestations that can lead to serious complications such as thrombosis of the subclavian vein or superior vena cava, mainly in patients with significant inflammatory involvement of the anterior-chest-wall. The objective of this study was to review the cases published in the medical literature related with the presence of thrombotic complications in patients diagnosed with SAPHO syndrome and to try to determine their possible pathogenic mechanism and risk factors. We analyzed 11 published reports of isolated clinical cases or case series, a total of 144 patients, which described a total of 15 cases of venous thrombosis. The clinical characteristics of these patients, evaluated to determine whether they meet the ASAS criteria for axial and peripheral spondyloarthritis, is analyzed the need for early diagnosis and treatment is highlighted.

1998-01-01

Chronic recurrent multifocal osteomyelitis (CRMO) is an unusual clinical entity. More than 200 cases are described in the literature and it is presented here with special reference to its radiological aspects. It is an acquired disease of the skeleton which occurs predominantly during childhood and adolescence. About ten per cent of cases begin in early or, rarely, in later adult life. This variant is described here for the first time and is discussed as 'adult CRMO'. The underlying pathology is a bland, predominantly lympho-plasma cellular osteomyelitis which is self-limiting and leads to bone sclerosis (Garre). It probably involves an abnormal immune process which follows an infection but remains clinically latent and remains aseptic and sterile. In a quarter of cases there is an association with pustulosis palmo-plantaris and its relationship with psoriatic arthropathy is discussed. The clinical, histopathological and imaging features (radiological and particularly MRT) and the bone changes are described. (orig./AJ) [de

Spondarthritis hyperostotica pustulo-psoriatica - Review and a clinical-radiological study with special emphasis on SAPHO syndrome; Die Spondarthritis hyperostotica pustulo-psoriatica: Nosologische Studie mit klinischer und radiologischer Darstellung innerhalb des SAPHO-Syndroms

Spondarthritis hyperostotica pustulo-psoriatica (Spond.hyp.pp-Schilling), corresponding nosologically to pustulotic arthroosteitis, is a dermato-skeletal `double system` disease of adults. It consists of the triad (a) palmo-plantar pustulosis (Ppp) or, alternatively, Koenigsbeck-Barber-type psoriasis, (b) sternocostoclavicular hyperostosis (SCCH), and (c) truncal-skeletal changes with syndesmophite-like, hyperostotic and/or parasyndesmophite-like ossifications of layers of the anterior vertebral ligament taken together in the sense of a desmophytal hyperostosis. There is also a potential for sclerosing inflammatory arthritis of the sacro-iliac joints and `dry` inflammatory arthritis of the sacro-iliac joints and `dry` inflammatory arthritis of peripheral joints. Thus, the pustulo-psoriatic terrain seems to have a decisive influence on osseous pathology. A total of 38 cases from a study during the years 1982 to 1992 is analysed with regard to morphological characteristics. Rare cases with diaphyseal and pelvic hyperostotic lesions subsequent to bland sclerosing osteomyelitis constitute an overlapping region to chronic recurrent multifocal osteomyelitis (CRMO) and illustrate the relationship between hyperostotic spondarthritis and CRMO. The syndromes of `acquired hyperostosis` and `SAPHO`, the former more radiologically oriented and the latter more clinically oriented, together with mainly CRMO and hyperostotic spondarthritis and its forms, constitute the `Spond.hyp.pp.`. Although hyperostosis is a guidepost for the radiologist and SAPHO symptoms are one for the clinician, the syndrome does not represent a diagnosis by itself and requires further differentiation. In this report the entity `Spond.hyp.pp.` is considered and requires contributions from rheumatologically and osteologically oriented radiologist. (orig.)

Metal Allergy and Systemic Contact Dermatitis: An Overview

Directory of Open Access Journals (Sweden)

Yoko Yoshihisa

2012-01-01

Full Text Available Contact dermatitis is produced by external skin exposure to an allergen, but sometimes a systemically administered allergen may reach the skin and remain concentrated there with the aid of the circulatory system, leading to the production of systemic contact dermatitis (SCD. Metals such as nickel, cobalt, chromium, and zinc are ubiquitous in our environment. Metal allergy may result in allergic contact dermatitis and also SCD. Systemic reactions, such as hand dermatitis or generalized eczematous reactions, can occur due to dietary nickel or cobalt ingestion. Zinc-containing dental fillings can induce oral lichen planus, palmoplantar pustulosis, and maculopapular rash. A diagnosis of sensitivity to metal is established by epicutaneous patch testing and oral metal challenge with metals such as nickel, cobalt, chromium, and zinc. In vitro tests, such as the lymphocyte stimulating test (LST, have some advantages over patch testing to diagnose allergic contact dermatitis. Additionally, the determination of the production of several cytokines by primary peripheral blood mononuclear cell cultures is a potentially promising in vitro method for the discrimination of metal allergies, including SCD, as compared with the LST.

Six females with nearly identical sclerotic and hyperostotic changes of the manubrium sterni are reported. Malignancies, bacterial inflammatory processes, and Paget disease, which were first suspected, could be excluded. The youngest patients also had sclerotic changes of other bones, including the lumbar spine, the pubic bone, and the clavicle, and may be classified as having ''chronic recurrent multifocal osteomyelitis'' (CRMO). The two oldest patients had ossification of the costoclavicular ligament(s) and may be classified as having ''inter-sterno-costo-clavicular ossification'' (ISCCO). One had only hyperostotic and sclerotic changes as seen in ''sterno-costo-clavicular hyperostosis'' (SCCH). The pathogenesis of these uncommon diseases is unknown, but they are all frequently associated with pustulosis palmoplantaris and have similar clinical courses and laboratory abnormalities. None of the present patients had HLA-B 27 . The similarity of the radiological abnormalities of the manubrium sterni suggests that the diseases themselves may be similar, but with different courses depending on age, CRMO being present in children and young adults and ISCCO or SCCH in older adults.

Carbon nanotubes with silver nanoparticle decoration and conductive polymer coating for improving the electrical conductivity of polycarbonate composites

KAUST Repository

Patole, Archana S.

2015-01-01

We proposed a strategy to enhance the conductivity of polycarbonate by using three-phase hybrid metallic/non-metallic fillers. Ethylene diamine (EDA) functionalized multiwalled carbon nanotubes (MWCNT-EDA) are first decorated with silver nanoparticles. These Ag/ MWCNT-EDA fillers are then coated with a conductive layer of ethylene glycol treated PEDOT: PSS (poly [3,4-ethylenedioxythiophene]: poly [styrenesulfonate]) (EP). In such an approach, the MWCNT backbone is covered by a highly conductive coating made of Ag nanoparticles surrounded by EP. To understand how Ag and EP form a highly conductive coating, the effect of different wt% of Ag nanoparticles on EP was studied. Ag nanoparticles around the size of 128 ± 28 nmeffectively lowered the volume resistivity of bulk EP, resulting in a highly conducting Ag/EP blend. We found that in the final Ag/MWCNT-EDA/EP assembly, the EP coating enhances the electrical conductivity in two ways: (1) it is an efficient dispersing agent that helps in achieving a uniform dispersion of the Ag/MWCNT-EDA and (2) it acts as a conductive bridge between particles (Ag and MWCNT-EDA), reducing the particle to particle resistivity. When inserted into polycarbonate, this three-phase blend successfully reduced the volume resistivity of the polymer by two orders of magnitude compared with previous approaches.

Despite the fact that smallpox eradication was declared by the World Health Organization (WHO) in 1980, other poxviruses have emerged and re-emerged, with significant public health and economic impacts. Vaccinia virus (VACV), a poxvirus used during the WHO smallpox vaccination campaign, has been involved in zoonotic infections in Brazilian rural areas (Bovine Vaccinia outbreaks - BV), affecting dairy cattle and milkers. Little is known about VACV's natural hosts and its epidemiological and ecological characteristics. Although VACV was isolated and/or serologically detected in Brazilian wild animals, the link between wildlife and farms has not yet been elucidated. In this study, we describe for the first time, to our knowledge, the isolation of a VACV (Mariana virus - MARV) from a mouse during a BV outbreak. Genetic data, in association with biological assays, showed that this isolate was the same etiological agent causing exanthematic lesions observed in the cattle and human inhabitants of a particular BV-affected area. Phylogenetic analysis grouped MARV with other VACV isolated during BV outbreaks. These data provide new biological and epidemiological information on VACV and lead to an interesting question: could peridomestic rodents be the link between wildlife and BV outbreaks?

Subject and Methods: 50 diagnosed cases of hyperthyroidism (44 females and 6 males of age ranging 21-40 years) were examined in detail for cutaneous changes and associated disorders. Results: Dermatological abnormalities were observed in 96% patients. Common manifestations of hyperthyroidism were altered skin texture in 48 (96%) and increased skin temperature in 46 (92%) patients. Other cutaneous findings included hyperhidrosis in 34(68%), generalized pruritus in 15 (30%), hyperpigmentation in 15 (30%) and pre tibial myxedema in 2 (4%) patients. Hair and nail changes were observed in 36 (72%) and 25 (50%) patients, respectively. Other associated autoimmune diseases seen were urticaria in 20 (40%) vitiligo in 12 (24%) alopecia areata in 4 (8%) and systemic lupus erythematosus in a 2% patient. Pustulosis palmoplantar is and xanthelasma were seen in one patient each. Conclusion: cultaneous examination can provide important clues to the diagnosis of hyperthyroidism. (author)

Post-infective transverse myelitis following Streptococcus pneumoniae meningitis with radiological features of acute disseminated encephalomyelitis: a case report

Williams Thomas

2012-09-01

Full Text Available Abstract Introduction Post-infectious autoimmune demyelination of the central nervous system is a rare neurological disorder typically associated with exanthematous viral infections. We report an unusual presentation of the condition and a previously undocumented association with Streptococcus pneumonia meningitis. Case presentation A 50-year-old Caucasian woman presented to our facility with an acute myelopathy three days after discharge following acute Streptococcus pneumoniae meningitis. Imaging studies of the spine ruled out an infective focus and no other lesions were seen within the cord. Diffuse, bilateral white matter lesions were seen within the cerebral hemispheres, and our patient was diagnosed as having a post-infective demyelination syndrome that met the diagnostic criteria for an acute transverse myelitis. Our patient clinically and radiologically improved following treatment with steroids. Conclusions The novel association of a Streptococcus pneumoniae infection with post-infectious autoimmune central nervous system demyelination should alert the reader to the potentially causative role of this common organism, and gives insights into the pathogenesis. The unusual dissociation between the clinical presentation and the location of the radiological lesions should also highlight the potential for the condition to mimic the presentation of others, and stimulates debate on the definitions of acute transverse myelitis and acute disseminated encephalomyelitis, and their potential overlap.

Full Text Available Abstract Introduction: the infection of chikungunya virus presents clinical manifestations variables, particularly in infants in which may present multiple cutaneous manifestations. Description: a case series study was carried out in an analytical character of 14 infants (>28 days to < 2 years old admitted in a hospital between November 2015 and January 2016 with suspected case of chikungunya, by a specific IgM reactive serology. Patients positive for dengue fever, Zika virus, bacterial infections and other exanthematic diseases were excluded. Fever and cutaneous alterations were the most frequent clinical manifestations in 100% of the cases, followed by irritability (64.3%, vomits and arthralgia/arthritis in 35.7% each. Three children presented alterations in the cerebrospinal fluid compatible to meningitis. Anemia frequency was 85.7%. The median white blood cells count was 7.700/mm3 (2.600 to 20.300/mm3. High levels of aminotransferases were observed in three cases (230 to 450 U/L. Antibiotic therapy was indicated in 64.3% of the cases. Two infants needed opioid derivatives for analgesia while others took acetaminophen and/or dipyrone. Discussion: the study shows evident multi-systemic involvement of chikungunya infection in infants. The treatment is supportive, giving special attention to hydration, analgesia, skin care, and rational use of antibiotic therapy.

Neonatal breast hypertrophy is a common phenomenon in term infants, superadded infection can lead to mastitis and that can progress to breast abscess with short and long term detrimental effects. Our effort is to study the prevalence, risk factors, the current microbial profile and sensitivity pattern in these infections in order to suggest an optimal treatment plan for these patients. Case series. Hospital based study conducted in Kashmir on the native population. 2011 to 2013. 32 neonates with features of mastitis or abscess were included in the study. Demographic and clinical data, laboratory work-up were recorded for all these patients in a patient form. Gram stain of the purulent nipple discharge or pus obtained on drainage was done and the specimens were culture plated. Antibiotic sensitivity was determined by disk diffusion and categorized by current Clinical and Laboratory Standards Institute (CLSI) guidelines. Most babies were full term, the age range was 6-48 days. Peak incidence for mastitis was in the 2nd week and for abscess in the 4th week. The ratio of male: female was 1:2 in the entire group, there was greater preponderance of female involvement with increasing age. Massage for expression of secretions a common practice in the study population had been done in 15 patients, especially in male babies. The babies were generally well and associated skin pustulosis was common. Laboratory workup showed polymorphonuclear leucocytosis and CRP positivity. Gram staining showed gram positive cocci in 13 patients and gram negative rods in 1 patient. Culture revealed Staphylococcus aureus in 18, E.col in 2, klebsiella in 1 patient and was sterile in 2 patients. Most strains of Staphylococcus aureus were resistant to macrolides and penicillins. Fifteen were methicillin sensitive and 3 were resistant but were sensitive to amikacin, ofloxacin and vancomycin. Gram negative rods were sensitive to, aminoglycosides, chloramphenicol, quinolones, piperacillin

SAPHO syndrome is well known to various disease entities including synovitis, acne, pustulosis, hyperostosis and polyarthritis. The purpose of this study is to evaluate sicntigraphic findings and to compare with radiologic findings in SAPHO syndrome. Five patients (M:F=5:0, Age 22.8{+-}4.78 yrs) with SAPHO syndrome were enrolled in our study. All patients underwent whole-body bone scintigraphy with intravenous administration of 740 MBq of Tc-99m MDP. Among them, two patients were additionally perfomed SPECT of the spine to evaluate the location and extent of spinal lesion. All patients were demonstrated abnormal increased uptakes in sternoclavicular joint (SC), sacroiliac joint (SI), and small joints of both hands. Among them, three patients were bilateral involvement (3/5) and two were unilateral (2/5) in SC. Involvement of SI showed bilateral in four patients (4/5) and unilateral in one (1/5). SPECT images demonstrate that the lesion sites of the lumbar spine are more likely facet joints than vertebral bodies or pedicles. As SAPHO syndrome is the disease entity involved polyarticular joints with various dermatologic manifestations, the bone scintigraphy may be a very useful method to evaluate the location and extent of joint involvement, and to avoid inadequate surgical management or ineffective antibiotic treatment.

We aimed to define central venous stenosis (CVS) caused by sternocostoclavicular hyperostosis as a feature of synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome on routine contrast-enhanced computed tomography (CT) images. The relationship between SAPHO syndrome and CVS without venous thrombosis caused by anterior chest wall compression has not been investigated. Therefore, the present study evaluated CVS in patients with SAPHO syndrome at our hospital. We retrospectively reviewed contrast-enhanced CT images of ten patients with suspected or diagnosed SAPHO syndrome between January 2007 and November 2015. The patients were assessed by contrast-enhanced CT using 16-, 64- or 128-detector row scanners. Two radiologists independently assessed the presence of CVS or obstruction and SAPHO syndrome in a retrospective review of CT images. Six of the ten patients had findings of CVS with SAPHO syndrome. The mean diameter and patency rate at the site of CVS were 1.88 mm and 27.2%, respectively. Stenosis was more significant in terms of the mean diameter of CVS sites than of stenotic sites that crossed the anteroposterior vein (p < 0.05). Radiologists who routinely assess contrast-enhanced CT images should be aware that sternocostoclavicular hyperostosis with SAPHO syndrome could cause secondary CVS. (orig.)

21 cases of spinocellular carcinoma (2 cases of them complicated basal-cell carcinoma) and a case of fibrosarcoma following irradiation were observed. The source which poses some problems in soft x-ray used for the treatment. Soft x-ray is used for the treatment of eczema, progressive keratodermia palmaris et plantaris, pustulosis palmaris et plantaris, trichophytia, hemangioma etc.. However, details of the irradiation are unknown in many of the cases. Carcinogenesis was noted 10 years at least-36 years at most after the irradiation. In 7 cases of 12 which received soft x-ray irradiation (including superficial therapy), multiple or double cancer was observed. In many of the cases, irradiation is repeated at low voltage, and radiation keratosis preceded cancerization. As the therapy of this type of keratosis, wide excision and skin grafting are generally recommended. The prognoses of the cases which received this therapy seem to be favorable. There were 6 cases of death out of 22 cases. The mortality (23.8%) is not high except for that of fibrosarcoma. Utilization of radiotherapy for skin diseases in future will be judged after a long-period followup. However, repeated irradiation for a long period, even if the source is extra-soft or limiting ray, should be avoided. (Ueda, J.)

Full Text Available Chronic eczematous hand dermatoses with and without contact allergies are complex diseases, which makes it a challenge to select the best treatment and obtain an optimal patient experience and a satisfactory treatment result. The aim of this study was to evaluate retrospectively the clinical effect and patient experience of local treatment with psoralen plus ultraviolet A (PUVA soaks and TL01 phototherapy for severe chronic hand dermatoses, and also to evaluate the quality of life for the subgroup of patients with allergic contact dermatitis including Compositae allergy. A retrospective evaluation of results for 94 consecutive patients having received a total of 121 treatment courses with local PUVA soaks or TL01 phototherapy for one of the following diagnoses (n=number of treatment courses: psoriasis (n=19, hyperkeratotic hand eczema (n=27, Pustulosis Palmoplantaris (PPP (n=22, vesicular eczema (n=16, Compositae dermatitis (n=24, and allergic contact dermatitis (n=13. Moreover, semi-structured interviews with 6 selected patients having multiple contact allergies including Compositae allergy were used to evaluate quality of life. As a result, we found that PUVA soaks has good effect in patients with psoriasis and hyperkeratotic hand eczema and local phototherapy for chronic hand dermatoses is a useful treatment option in selected cases.

Data were weighed according to gender and age of the Dutch population.At baseline 20.5% reported MC. At three-year follow-up, 15.4% had incident MC. No associations were found between employment status and MC. Adjusted analysis revealed that individuals with high occupational cognitive demands were more likely to have prevalent MC.Middle-aged workers are equally as likely to experience MC as non-working age-peers. Among workers, those with cognitively demanding work were more likely to experience MC, independent of memory performance. Memory decline due to ageing may be noticed sooner in 55-64-year-olds performing cognitively demanding work.

Patients with Parkinson's disease (PD) are perceived more negatively than their healthy peers, yet it remains unclear what factors contribute to this negative social perception. Based on a cohort of 17 PD patients and 20 healthy controls, we assessed how naïve raters judge the emotion and emotional intensity displayed in dynamic facial expressions as adults with and without PD watched emotionally evocative films (Experiment 1), and how age-matched peers naïve to patients' disease status judge their social desirability along various dimensions from audiovisual stimuli (interview excerpts) recorded after certain films (Experiment 2). In Experiment 1, participants with PD were rated as significantly more facially expressive than healthy controls; moreover, ratings demonstrated that PD patients were routinely mistaken for experiencing a negative emotion, whereas controls were rated as displaying a more positive emotion than they reported feeling. In Experiment 2, results showed that age-peers rated PD patients as significantly less socially desirable than control participants. Specifically, PD patients were rated as less involved, interested, friendly, intelligent, optimistic, attentive, and physically attractive than healthy controls. Taken together, our results point to a disconnect between how PD patients report feeling and attributions that others make about their emotions and social characteristics, underlining significant social challenges of the disease. In particular, changes in the ability to modulate the expression of negative emotions may contribute to the negative social impressions that many PD patients face.

Pox and pox-like diseases of camels are a group of exanthematous skin conditions that have become increasingly important economically. Three distinct viruses may cause them: camelpox virus (CMLV), camel parapox virus (CPPV) and camelus dromedary papilloma virus (CdPV). These diseases are often difficult to differentiate based on clinical presentation in disease outbreaks. Molecular methods such as PCR targeting species-specific genes have been developed and used to identify these diseases, but not simultaneously in a single tube. Recently, multiplex PCR has gained reputation as a convenient diagnostic method with cost-and timesaving benefits. In the present communication, we describe the development, optimization and validation of a multiplex PCR assay able to detect simultaneously the genome of the three viruses in one single test allowing for rapid and efficient molecular diagnosis. The assay was developed based on the evaluation and combination of published and new primer sets and was validated with viral genomic DNA extracted from known virus strains (n = 14) and DNA extracted from homogenized clinical skin specimens (n = 86). The assay detects correctly the target pathogens by amplification of targeted genes, even in case of co-infection. The method showed high sensitivity, and the specificity was confirmed by PCR-product sequencing. This assay provide rapid, sensitive and specific method for identifying three important viruses in specimens collected from dromedary camels with varying clinical presentations.

The lymphocyte transformation test (LTT) has been promoted as in-vitro test for diagnosis of drug hypersensitivity. For determination of statistical LTT sensitivity, series of patients with clinically uniform reactions followed by complete drug hypersensitivity work-up are mandatory. Assessment of LTT specificity requires control patients who tolerated exposure to the drug studied. To prospectively determine the diagnostic value of the LTT in a clinically and diagnostically well-defined series of patients. Patients with exanthematous skin eruptions after ampicillin (AMP) intake were included in this study. After exclusion or confirmation of delayed-onset allergic AMP hypersensitivity by skin and provocation testing, two independent LTTs were performed: one standard LTT and a modified LTT with additional anti-CD3/anti-CD28 monoclonal antibody stimulation. By testing, delayed-onset allergic AMP hypersensitivity was diagnosed in 11 patients and definitely ruled out in 26. The standard LTT reached a diagnostic sensitivity of 54.5% while the modified LTT yielded 72.7%. However, the methodical test modification resulted in a decline of specificity from 92.3% (standard LTT) to 76.9%. In cases of AMP-associated exanthems, the diagnostic value of the LTT compared with routine allergy testing is limited. When evaluating such exanthems, provocation testing remains the gold standard. Delayed reading of intradermal skin tests remains most useful to avoid positive provocation reactions. © 2014 John Wiley & Sons Ltd.

Full Text Available Introduction. Pityriasis rosea (PR is an exanthematous disease related to human herpesvirus- (HHV- 6/7 reactivation. The network of mediators involved in recruiting the infiltrating inflammatory cells has never been studied. Object. To investigate the levels of serum cytokines, growth factors, and chemokines in PR and healthy controls in order to elucidate the PR pathogenesis. Materials and Methods. Interleukin- (IL- 1, IL-6, IL-17, interferon- (IFN- γ, tumor necrosis factor- (TNF- α, vascular endothelial growth factor (VEGF, granulocyte colony stimulating factor (G-CSF, and chemokines, CXCL8 (IL-8 and CXCL10 (IP-10, were measured simultaneously by a multiplex assay in early acute PR patients’ sera and healthy controls. Subsequently, sera from PR patients were analysed at 3 different times (0, 15, and 30 days. Results and discussion. Serum levels of IL-17, IFN-γ, VEGF, and IP-10 resulted to be upregulated in PR patients compared to controls. IL-17 has a key role in host defense against pathogens stimulating the release of proinflammatory cytokines/chemokines. IFN-γ has a direct antiviral activity promoting NK cells and virus specific T cells cytotoxicity. VEGF stimulates vasculogenesis and angiogenesis. IP-10 can induce chemotaxis, apoptosis, cell growth, and angiogenesis. Conclusions. Our findings suggest that these inflammatory mediators may modulate PR pathogenesis in synergistic manner.

AIM: To conduct a retrospective study to determine the risk factors for development of metaplastic gastritis in Korean population.METHODS: The database of 113449 subjects who underwent a gastroscopy for the purpose of a regular check-up at center for health promotion, Samsung medical center during 5 years was collected and retrospectively analyzed. Among them, 5847 subjects who had endoscopically diagnosed as a metaplastic gastritis or 10076 normal as well as answered to questionnaire were included for present study. The subjects were divided into 2 groups; Group Ⅰ, normal and Group Ⅱ, metaplastic gastritis. Age, gender, Helicobacter pylori(H pylori) seropositivity, body mass index (BMI),family history of cancer, smoking, alcohol consumption,total daily calories, folate and salt intake and dietary habit (out-eating, overeating, irregular eating) were retrieved from questionnaire or electronic medical record and compared between group Ⅰ and group Ⅱ.RESULTS: The prevalence of group Ⅱ was 11%(13578/113449) increasing its prevalence with age(P= 0.000). But, there was no significant association between 2 groups in BMI, family history of cancer,alcohol consumption, total daily calories, folate and salt intake and dietary habit (out-eating, overeating, irregular eating). Old age (P=0.000), male gender (P=0.000),H pylori seropositivity (P= 0.010) and current smoker (P= 0.000) were significantly more common in group Ⅱ at multiple logistic regression model.CONCLUSION: Our data suggested that old age, male gender,Hpyloriseropositivity and smoking were risk factors for metaplastic gastritis, precancerous lesion of gastric cancer.

Ectromelia virus is the causative agent of mousepox, an acute exanthematous disease of mouse colonies in Europe, Japan, China, and the U.S. The Moscow, Hampstead, and NIH79 strains are the most thoroughly studied with the Moscow strain being the most infectious and virulent for the mouse. In the late 1940s mousepox was proposed as a model for the study of the pathogenesis of smallpox and generalized vaccinia in humans. Studies in the last five decades from a succession of investigators have resulted in a detailed description of the virologic and pathologic disease course in genetically susceptible and resistant inbred and out-bred mice. We report the DNA sequence of the left-hand end, the predicted right-hand terminal repeat, and central regions of the genome of the Moscow strain of ectromelia virus (approximately 177,500 bp), which together with the previously sequenced right-hand end, yields a genome of 209,771 bp. We identified 175 potential genes specifying proteins of between 53 and 1924 amino acids, and 29 regions containing sequences related to genes predicted in other poxviruses, but unlikely to encode for functional proteins in ectromelia virus. The translated protein sequences were compared with the protein database for structure/function relationships, and these analyses were used to investigate poxvirus evolution and to attempt to explain at the cellular and molecular level the well-characterized features of the ectromelia virus natural life cycle

In this article devoted to Poland's direct and indirect role in the elaboration of contemporary international health structures and to her reputation as an epidemic reservoir of Europe, we consider how Poland came to be perceived as the cordon sanitaire of the West. Traditionally seen as upholding Western values, in the 19th and 20th centuries the country became increasingly associated with "Eastern plagues"-cholera and then typhus-coming from Russia and which could spread to the rest of Europe if Poland did not manage to contain them. When Poland was reconstituted as a nation-state in 1918, the new country won international recognition through her successful attempts to contain a typhus epidemic sweeping westwards from Russia. The Polish government convened the first European, League sponsored, health conference following the First World War. A Polish doctor, L. RAJCHMAN, was chosen to head up the League of Nations Health Organisation (forerunner of the WHO) and later (1946) founded UNICEF. Finally, we examine the key issue of exanthematous typhus in both world wars, exemplifying how a disease can come to be "ideologized", in this case by Nazi Germany. Typhus was the pretext used- in the name of "public health"-for segregating Polish citizens of Jewish origin and even killing them. Paradoxically, typhus was in the process of being eradicated when the war began and German policy of mass resettlements, sequestration, and starvation only spurred the epidemic they supposedly wished to control.

Several studies have been conducted in China in order to investigate the potential predictors of serofast state after treatment among syphilitic patients. However, there is a remarkable diversity among the results. This meta-analysis was conducted to assess potential predictors of serofast among syphilitic patients in China. International and national electronic databases were searched up to September 2013. Reference lists of retrieved articles were also reviewed. Cohort or case-control studies addressing risk factors of serofast among syphilitic patients were included in this study. We assessed 27 separate studies involving overall 6682 HIV-negative participants with syphilis of which 1962 remained in the serofast state. The serofast was positively associated with older age(P trend=0.001), female(summary risk ratio[sRR]=1.50, 95%CI:1.34-;1.68), latent syphilis(sRRlatent vs primary=3.17, 95%CI: 2.66-;3.77; sRRlatent vs secondary=2.00, 95%CI: 1.48-;2.69) as well as non-penicillin treatment(sRR =2.99, 95%CI:2.45-;3.67), but negatively associated with higher baseline titers(sRR>1:32 vs ≤1:32=0.63, 95%CI: 0.54-;0.75). Compared with healthy group and serological cure group, respectively, the levels of CD4 (+), IL-2, and IL-6 among serofast patients were decreased (standardized mean difference[SMD]SMD>0, Pinfection. The age, gender, stage of infection, baseline titers, treatment drug, cellular immune suppression and disorders, TP occult infection and subtypes i of TP repeat gene should be considered as important predictors of serofast. However, until now the definition and mechanism of serofast has still been not clear.

SAPHO syndrome is a rare and often unrecognized disease with prominent inflammatory cutaneous and articular symptoms characterized by musculoskeletal manifestations (synovitis, hyperostosis, osteomyelitis) associated with dermatological conditions (severe acne and pustulosis). The acidic soluble fraction of whole saliva from 10 adult women affected by SAPHO syndrome and from a group of 28 healthy women was analysed by RP-HPLC-ESI-MS with the aim of discovering salivary biomarkers of the disorder. The levels of the oral proteins and peptides were correlated with clinical data. The following proteins showed a significant decreased concentration in saliva of SAPHO subjects with respect to controls: cystatin S1 and SN, histatins, the major acidic PRPs, P-C and P-B peptides. The cystatin SN abundance lowered according to the disease duration and histatins showed positive correlations with the C reactive protein. Statistical analysis performed excluding one patient with a different pattern of salivary proteins/peptides highlighted a positive relationship between cystatin S1, histatins 3, histatin 5, and the neutrophil count. Moreover, histatin 3 correlated positively with the total white cell count and negatively with the erythrocyte sedimentation rate. Levels and frequency of S100A12 protein showed a trend to increase in SAPHO patients. The high expression of this pro-inflammatory protein is probably related to the inflammatory response and to the altered neutrophil responses to functional stimuli that characterize SAPHO syndrome suggesting a possible application as a salivary biomarker.

Zika is a new disease in the American continent and its surveillance is of utmost importance, especially because of its ability to cause neurological manifestations as Guillain-Barré syndrome and serious congenital malformations through vertical transmission. The detection of suspected cases by the surveillance system depends on the case definition adopted. As the laboratory diagnosis of Zika infection still relies on the use of expensive and complex molecular techniques with low sensitivity due to a narrow window of detection, most suspected cases are not confirmed by laboratory tests, mainly reserved for pregnant women and newborns. In this context, an accurate definition of a suspected Zika case is crucial in order for the surveillance system to gauge the magnitude of an epidemic. We evaluated the accuracy of various Zika case definitions in a scenario where Dengue and Chikungunya viruses co-circulate. Signs and symptoms that best discriminated PCR confirmed Zika from other laboratory confirmed febrile or exanthematic diseases were identified to propose and test predictive models for Zika infection based on these clinical features. Our derived score prediction model had the best performance because it demonstrated the highest sensitivity and specificity, 86·6% and 78·3%, respectively. This Zika case definition also had the highest values for auROC (0·903) and R2 (0·417), and the lowest Brier score 0·096. In areas where multiple arboviruses circulate, the presence of rash with pruritus or conjunctival hyperemia, without any other general clinical manifestations such as fever, petechia or anorexia is the best Zika case definition.

Drug hypersensitivity reactions are unpredictable adverse drug reactions. They manifest either within 1-6 h following drug intake (immediate reactions) with mild to life-threatening symptoms of anaphylaxis, or several hours to days later (delayed reactions), primarily as exanthematous eruptions. It is not always possible to detect involvement of the immune system (allergy). Waiving diagnostic tests can result in severe reactions on renewed exposure on the one hand, and to unjustified treatment restrictions on the other. With this guideline, experts from various specialist societies and institutions have formulated recommendations and an algorithm for the diagnosis of allergies. The key principles of diagnosing allergic/hypersensitivity drug reactions are presented. Where possible, the objective is to perform allergy diagnostics within 4 weeks-6 months following the reaction. A clinical classification of symptoms based on the morphology and time course of the reaction is required in order to plan a diagnostic work-up. In the case of typical symptoms of a drug hypersensitivity reaction and unequivocal findings from validated skin and/or laboratory tests, a reaction can be attributed to a trigger with sufficient confidence. However, skin and laboratory tests are often negative or insufficiently reliable. In such cases, controlled provocation testing is required to clarify drug reactions. This method is reliable and safe when attention is paid to indications and contraindications and performed under appropriate medical supervision. The results of the overall assessment are discussed with the patient and documented in an "allergy passport" in order to ensure targeted avoidance in the future and allow the use of alternative drugs where possible.

Objective to assess the neutrophil function in thalassemia major (TM)patients and compare it with the control group and to recognize its relevantfactors. This was a retrospective cohort study, which was carried out fromOctober 2007 to February 2008 in the Thalassemia research Center in Boo AliSina Hospital in Sari, Mazandaran, North of Iran. The study populationconsisted of TM patients in Boo Ali Sina Teaching Hospital. The method ofsampling in the case group was systematic and it was target based in thecontrol group. The sample size determined was based on previous studies.Thalassemia major was diagnosed based on hemoglobin electrophoresis (casegroup). The control group was their brothers and sisters, who had +-5 yearsof age difference and were of the same gender as the patients. Datacollection was based on interview, investigating demographic characteristicsand also obtaining medical information from medical records of the patients.The neutrophil function was by performing nitroblue tetrazolium (NBT)reduction test. The test was carried out on both groups and the data wereanalyzed by software using SPSS version 13.0. In this study, 39 patients and39 healthy controls were compared. The average age of the patients was21.6+-5.3 years and it was 22.4+-5.1 years in healthy controls (p=0.7). Therewas a significant correlation between the test's results and the patients age(p=0.008). The rate of impaired NBT results in the patients was 36%, while itwas 10% in controls, which were significantly different. The neutrophilactivity based on NBT test was 89.9+-11.6% in the case group and 93.7+-2.51%in the control group (p=0.025). This study indicates that neutrophil activityin thalassemia patients was significantly lower, compared to the normalcontrol group, especially in young patients. Based on the results, evaluationof neutrophil function and pyogenic infections in TM patients seemsnecessary. (author)

Full Text Available This population-based study investigates genotype-phenotype correlations of low-normal CGG repeats in the fragile X mental retardation 1 (FMR1 gene. FMR1 plays an important role in brain development and function, and encodes FMRP (fragile X mental retardation protein, an RNA-binding protein that regulates protein synthesis impacting activity-dependent synaptic development and plasticity. Most past research has focused on CGG premutation expansions (41 to 200 CGG repeats and on fragile X syndrome (200+ CGG repeats, with considerably less attention on the other end of the spectrum of CGG repeats. Using existing data, older adults with 23 or fewer CGG repeats (2 SDs below the mean were compared with age-peers who have normal numbers of CGGs (24-40 with respect to cognition, mental health, cancer, and having children with disabilities. Men (n = 341 with an allele in the low-normal range and women (n = 46 with two low-normal alleles had significantly more difficulty with their memory and ability to solve day to day problems. Women with both FMR1 alleles in the low-normal category had significantly elevated odds of feeling that they need to drink more to get the same effect as in the past. These women also had two and one-half times the odds of having had breast cancer and four times the odds of uterine cancer. Men and women with low-normal CGGs had higher odds of having a child with a disability, either a developmental disability or a mental health condition. These findings are in line with the hypothesis that there is a need for tight neuronal homeostatic control mechanisms for optimal cognitive and behavioral functioning, and more generally that low numbers as well as high numbers of CGG repeats may be problematic for health.

Children with SLI exhibit overall deficits in novel word learning compared to their age-matched peers. However, the manifestation of the word learning difficulty in SLI was not consistent across tasks and the factors affecting the learning performance were not yet determined. Our aim is to examine the extent of word learning difficulties in Mandarin-speaking preschool children with SLI, and to explore the potent influence of existing lexical knowledge on to the word learning process. Preschool children with SLI (n=37) and typical language development (n=33) were exposed to novel words for unfamiliar objects embedded in stories. Word learning tasks including the initial mapping and short-term repetitive learning were designed. Results revealed that Mandarin-speaking preschool children with SLI performed as well as their age-peers in the initial form-meaning mapping task. Their word learning difficulty was only evidently shown in the short-term repetitive learning task under a production demand, and their learning speed was slower than the control group. Children with SLI learned the novel words with a semantic head better in both the initial mapping and repetitive learning tasks. Moderate correlations between stand word learning performances and scores on standardized vocabulary were found after controlling for children's age and nonverbal IQ. The results suggested that the word learning difficulty in children with SLI occurred in the process of establishing a robust phonological representation at the beginning stage of word learning. Also, implicit compound knowledge is applied to aid word learning process for children with and without SLI. We also provide the empirical data to validate the relationship between preschool children's word learning performance and their existing receptive vocabulary ability. Copyright © 2013 Elsevier Ltd.

We compared English language and cognitive skills between internationally adopted children (IA; mean age at adoption=2.24, SD=1.8) and their non-adopted peers from the US reared in biological families (BF) at two time points. We also examined the relationships between outcome measures and age at initial institutionalization, length of institutionalization, and age at adoption. On measures of general language, early literacy, and non-verbal IQ, the IA group performed significantly below their age-peers reared in biological families at both time points, but the group differences disappeared on receptive vocabulary and kindergarten concept knowledge at the second time point. Furthermore, the majority of children reached normative age expectations between 1 and 2 years post-adoption on all standardized measures. Although the age at adoption, age of institutionalization, length of institutionalization, and time in the adoptive family all demonstrated significant correlations with one or more outcome measures, the negative relationship between length of institutionalization and child outcomes remained most robust after controlling for the other variables. Results point to much flexibility and resilience in children's capacity for language acquisition as well as the potential primacy of length of institutionalization in explaining individual variation in IA children's outcomes. (1) Readers will be able to understand the importance of pre-adoption environment on language and early literacy development in internationally adopted children. (2) Readers will be able to compare the strength of the association between the length of institutionalization and language outcomes with the strength of the association between the latter and the age at adoption. (3) Readers will be able to understand that internationally adopted children are able to reach age expectations on expressive and receptive language measures despite adverse early experiences and a replacement of their first

Deficiency of interleukin-1 receptor antagonist (DIRA) is a rare life-threatening autoinflammatory disease caused by autosomal recessive mutations in IL1RN. DIRA presents clinically with early onset generalized pustulosis, multifocal osteomyelitis, and elevation of acute phase reactants. We evaluated and treated an antibiotic-unresponsive patient with presumed DIRA with recombinant IL-1Ra (anakinra). The patient developed anaphylaxis to anakinra and was subsequently desensitized. Genetic analysis of IL1RN was undertaken and treatment with anakinra was initiated. A 5-month-old Indian girl born to healthy non-consanguineous parents presented at the third week of life with irritability, sterile multifocal osteomyelitis including ribs and clavicles, a mild pustular rash, and elevated acute phase reactants. SNP array of the patient's genomic DNA revealed a previously unrecognized homozygous deletion of approximately 22.5 Kb. PCR and Sanger sequencing of the borders of the deleted area allowed identification of the breakpoints of the deletion, thus confirming a homozygous 22,216 bp deletion that spans the first four exons of IL1RN. Due to a clinical suspicion of DIRA, anakinra was initiated which resulted in an anaphylactic reaction that triggered desensitization with subsequent marked and sustained clinical and laboratory improvement. We report a novel DIRA-causing homozygous deletion affecting IL1RN in an Indian patient. The mutation likely is a founder mutation; the design of breakpoint-specific primers will enable genetic screening in Indian patients suspected of DIRA. The patient developed anaphylaxis to anakinra, was desensitized, and is in clinical remission on continued treatment.

Full Text Available Malassezia pachydermatis (M. pachydermatis is a fungus of importance in human and veterinary medicine. Although a part of the normal microbiota, it can sometimes be present in its pathogenic form, particularly causing otitis and dermatitis in animals. Among human beings, it mainly affects immune compromised patients and newborns, causing simple pustulosis, seborrheic dermatitis, tinea versicolor or fungemia. This study aimed to analyze the genomic polymorphism in M. pachydermatis samples isolated from Canis familiaris (domestic dog, Felis catus (domestic cat, and Myrmecophaga tridactyla (giant anteater. Two hundred and fourteen samples were collected and cultured in Sabouraud agar with chloranphenicol (100mg L-1 and incubated at 37 °C for a period of 7 to 10 days. One hundred and sixty six samples that appeared morphologically comparable to yeast cultures were processed for DNA extraction and PCR was performed for a specific region in the Internal Transcribed Spacer (ITS of M. pachydermatis. Among these, seven (4.21% were negative and 159 (95.79% were positive. Of the 159 positive samples, 102 (64.15% were from animals with clinical signs and 57 (35.85% without clinical signs. Fifty-seven samples were selected at random for RAPD-PCR based genotyping and distributed into four genetic groups. Types I and II were more frequent in animals with clinical signs while type III was frequent in healthy animals. Type IV occurred evenly across animals with or without clinical signs. These results indicate differences in pathogenicity of the fungus based on the genotype.

Whole-body bone scintigraphy (WBBS) and MRI are widely used in assessment of patients with synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome. However, the value of F-18 fluorodeoxyglucose-positron emission tomography/computed tomography ( 18 F-FDG PET/CT) in SAPHO syndrome was unclear. The aim of this study was to characterize the manifestation of SAPHO syndrome on 18 F-FDG PET/CT and explore its relationship with clinical symptoms and WBBS. Twenty-six patients who suffered from SAPHO syndrome and had undergone whole-body 18 F-FDG PET/CT were recruited in Peking Union Medical College Hospital from 2004 to 2016. Clinical manifestations and laboratory findings were recorded for all patients. Imaging data on 18F-FDG PET/CT and WBBS were collected and analyzed retrospectively. All the 26 patients (20 females and 6 males) exhibited skeletal abnormalities on 18 F-FDG PET/CT. Multiple skeletal lesions affecting the anterior chest wall or spine with low to moderate 18 F-FDG uptake and coexistence of osteolysis and osteosclerosis presented as the typical features of SAPHO syndrome. Sixteen (61.5%) patients had abnormal 18 F-FDG uptake outside the osteoarticular system. PET scan had moderate to substantial agreement with CT and WBBS in revealing lesions in the anterior chest wall and axial skeleton. Nonetheless, the correlation between increased 18 F-FDG uptake and clinical symptoms was weak. SAPHO syndrome exhibits characteristic features on 18 F-FDG PET/CT. It showed comparable capacity in revealing skeletal lesions with bone scintigraphy.

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.

Spondarthritis hyperostotica pustulo-psoriatica - Review and a clinical-radiological study with special emphasis on SAPHO syndrome

1998-01-01

Spondarthritis hyperostotica pustulo-psoriatica (Spond.hyp.pp-Schilling), corresponding nosologically to pustulotic arthroosteitis, is a dermato-skeletal 'double system' disease of adults. It consists of the triad (a) palmo-plantar pustulosis (Ppp) or, alternatively, Koenigsbeck-Barber-type psoriasis, (b) sternocostoclavicular hyperostosis (SCCH), and (c) truncal-skeletal changes with syndesmophite-like, hyperostotic and/or parasyndesmophite-like ossifications of layers of the anterior vertebral ligament taken together in the sense of a desmophytal hyperostosis. There is also a potential for sclerosing inflammatory arthritis of the sacro-iliac joints and 'dry' inflammatory arthritis of the sacro-iliac joints and 'dry' inflammatory arthritis of peripheral joints. Thus, the pustulo-psoriatic terrain seems to have a decisive influence on osseous pathology. A total of 38 cases from a study during the years 1982 to 1992 is analysed with regard to morphological characteristics. Rare cases with diaphyseal and pelvic hyperostotic lesions subsequent to bland sclerosing osteomyelitis constitute an overlapping region to chronic recurrent multifocal osteomyelitis (CRMO) and illustrate the relationship between hyperostotic spondarthritis and CRMO. The syndromes of 'acquired hyperostosis' and 'SAPHO', the former more radiologically oriented and the latter more clinically oriented, together with mainly CRMO and hyperostotic spondarthritis and its forms, constitute the 'Spond.hyp.pp.'. Although hyperostosis is a guidepost for the radiologist and SAPHO symptoms are one for the clinician, the syndrome does not represent a diagnosis by itself and requires further differentiation. In this report the entity 'Spond.hyp.pp.' is considered and requires contributions from rheumatologically and osteologically oriented radiologist. (orig.) [de

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.

Accuracy of Zika virus disease case definition during simultaneous Dengue and Chikungunya epidemics.

José Ueleres Braga

Full Text Available Zika is a new disease in the American continent and its surveillance is of utmost importance, especially because of its ability to cause neurological manifestations as Guillain-Barré syndrome and serious congenital malformations through vertical transmission. The detection of suspected cases by the surveillance system depends on the case definition adopted. As the laboratory diagnosis of Zika infection still relies on the use of expensive and complex molecular techniques with low sensitivity due to a narrow window of detection, most suspected cases are not confirmed by laboratory tests, mainly reserved for pregnant women and newborns. In this context, an accurate definition of a suspected Zika case is crucial in order for the surveillance system to gauge the magnitude of an epidemic.We evaluated the accuracy of various Zika case definitions in a scenario where Dengue and Chikungunya viruses co-circulate. Signs and symptoms that best discriminated PCR confirmed Zika from other laboratory confirmed febrile or exanthematic diseases were identified to propose and test predictive models for Zika infection based on these clinical features.Our derived score prediction model had the best performance because it demonstrated the highest sensitivity and specificity, 86·6% and 78·3%, respectively. This Zika case definition also had the highest values for auROC (0·903 and R2 (0·417, and the lowest Brier score 0·096.In areas where multiple arboviruses circulate, the presence of rash with pruritus or conjunctival hyperemia, without any other general clinical manifestations such as fever, petechia or anorexia is the best Zika case definition.

Clindamycin is a lincomycin-derived antibiotic useful for the treatment of anaerobic and Gram-positive aerobic bacterial infections. Cutaneous adverse reactions are usually maculopapular exanthemas, although hypersensitivity syndrome, acute generalized exanthematous pustulosis, and Stevens-Johnson syndrome have also been reported (1). We report the case of a patient with a maculopapular rash triggered by clindamycin who developed cutaneous lesions on striae distensae (SD). A 47-year-old woman was referred to our clinic for pruritic cutaneous lesions which had started 6 days earlier. Her past clinical history included hypertension, hypothyroidism, hyperuricemia, cholecystectomy, caesarean section, and endometriosis-related abdominal surgery, and she was taking levothyroxine, allopurinol, imidapril, and omeprazole. The skin rash first developed on her neck and back on the 3rd day of clindamycin oral treatment (300 mg every 6 hours), which was prescribed as antibiotic prophylaxis for a tooth implant. General malaise (but not fever) was also reported. Physical examination revealed an erythematous maculopapular eruption symmetrically distributed on the neck, abdomen, and back (Figure 1, A), with isolated lesions involving the proximal upper and lower limbs (Figure 1, B). There was a striking vertical distribution of skin lesions along the SD on the lateral sides of the abdomen (Figure 1, C). No mucosal involvement was found, and laboratory studies showed no abnormalities. Clindamycin withdrawal was followed by prescription of a course of oral deflazacort, starting at 30 mg daily and tapering down during a 9-day period. On the 5th day of treatment, the rash had almost cleared with minimal desquamation (Figure 1, D). Eight weeks after clearance of the skin rash, informed consent was obtained in order to perform an allergological evaluation of clindamycin, including prick and intradermal (ID) tests on the forearm and patch tests on the upper back (2).

Flomoxef (FMOX, 6315-S), a newly synthesized antibiotic which belongs to the oxacephem group, was clinically evaluated for its efficacy and safety in 17 patients with ages ranging from 1 month to 9 year-8-month who had bacterial infections. The results obtained were summarized as follows. 1. A pharmacokinetic study following 20 mg/kg FMOX administration by intravenous bolus injection showed that the half-life of FMOX (beta phase) was 39.8 minutes and the urinary excretion of FMOX in the first 6 hours was 76.5%. 2. FMOX was administered to 3 patients with pneumonia, 8 patients with bronchopneumonia, 2 patients with tonsillitis, 2 patients with pyelonephritis, one patient each with cervical lymphadenitis, and pustulosis associated with severe varicella at daily dosage levels of 61.9 approximately 87.2 mg/kg, divided into 3 or 4 administrations by intravenous bolus injection or by 30 minutes drip infusion. The clinical results of these 17 patients were as follows; excellent: 14 patients, good: 2 patients, poor: 1 patient. The efficacy rate was 94.1%. 3. No clinical adverse reaction was observed in any of the 17 patients. Neutropenia, eosinophilia, a slight elevation of GPT and slight elevations of GOT & GPT were observed in 1, 1, 1, and 2 patients, respectively. No abnormality in coagulation system was observed in any of 10 evaluable patients. 4. MICs of FMOX against 13 strains isolated from patients were as follows. MIC against 2 out of 3 strains of Streptococcus pneumoniae was 0.20 micrograms/ml and that of the remaining 1 strain was 0.39 micrograms/ml.(ABSTRACT TRUNCATED AT 250 WORDS)

The human population is currently faced with the potential use of natural or recombinant variola and monkeypox viruses as biological weapons. Furthermore, the emergence of human monkeypox in Africa and its expanding environs poses a significant natural threat. Such occurrences would require therapeutic and prophylactic intervention with antivirals to minimize morbidity and mortality of exposed populations. Two orally-bioavailable antivirals are currently in clinical trials; namely CMX001, an ether-lipid analog of cidofovir with activity at the DNA replication stage and ST-246, a novel viral egress inhibitor. Both of these drugs have previously been evaluated in the ectromelia/mousepox system; however, the trigger for intervention was not linked to a disease biomarker or a specific marker of virus replication. In this study we used lethal, intranasal, ectromelia virus infections of C57BL/6 and hairless SKH1 mice to model human disease and evaluate exanthematous rash (rash) as an indicator to initiate antiviral treatment. We show that significant protection can be provided to C57BL/6 mice by CMX001 or ST-246 when therapy is initiated on day 6 post infection or earlier. We also show that significant protection can be provided to SKH1 mice treated with CMX001 at day 3 post infection or earlier, but this is four or more days before detection of rash (ST-246 not tested). Although in this model rash could not be used as a treatment trigger, viral DNA was detected in blood by day 4 post infection and in the oropharyngeal secretions (saliva) by day 2-3 post infection - thus providing robust and specific markers of virus replication for therapy initiation. These findings are discussed in the context of current respiratory challenge animal models in use for the evaluation of poxvirus antivirals. Copyright © 2012 Elsevier B.V. All rights reserved.

Tropism and pathogenicity of rickettsiae

2012-06-01

Full Text Available Rickettsiae are obligate intracellular parasitic bacteria that cause febrile exanthematous illnesses such as Rocky Mountain spotted fever, Mediterranean spotted fever, epidemic and murine typhus, etc. Although the vector ranges of each Rickettsia species are rather restricted; i.e., ticks belonging to Arachnida and lice and fleas belonging to Insecta usually act as vectors for spotted fever group and typhus group rickettsiae, respectively, it would be interesting to elucidate the mechanisms controlling the vector tropism of rickettsiae. This review discusses the factors determining the vector tropism of rickettsiae. In brief, the vector tropism of rickettsiae species is basically consistent with their tropism towards cultured tick and insect cells. The mechanisms responsible for rickettsiae pathogenicity are also described. Recently, genomic analyses of rickettsiae have revealed that they possess several genes that are homologous to those affecting the pathogenicity of other bacteria. Analyses comparing the genomes of pathogenic and nonpathogenic strains of rickettsiae have detected many factors that are related to rickettsial pathogenicity. It is also known that a reduction in the rickettsial genome has occurred during the course of its evolution. Interestingly, Rickettsia species with small genomes, such as Rickettsia prowazekii, are more pathogenic to humans than those with larger genomes. This review also examines the growth kinetics of pathogenic and nonpathogenic species of spotted fever group rickettsiae in mammalian cells. The growth of nonpathogenic species is restricted in these cells, which is mediated, at least in part, by autophagy. The superinfection of nonpathogenic rickettsiae-infected cells with pathogenic rickettsiae results in an elevated yield of the nonpathogenic rickettsiae and the growth of the pathogenic rickettsiae. Autophagy is restricted in these cells. These results are discussed in this review.

To determine the frequency, etiology (viral infection or vaccination), presenting signs and symptoms, response to therapy, complication and course of acute disseminated encephalomyelitis (ADEM) in our hospitals. A 2-year retrospective, descriptive, chart review of children with final diagnosis of ADEM in 2 hospitals (Hazrat Rasool and Mofid in Tehran, Iran during 2000-2002) was carried out. The diagnosis is based upon clinical presentation, physical examination and ruling out of other disease (imaging, laboratories and so forth) of expert pediatric neurologists. Acute disseminated encephalomyelitis was documented in all cases by characteristics MRI changes included inflammation and demyelination in subcortical or periventricular regions. Acute disseminated encephalomyelitis were diagnosed in 15 patients. More than half of patients were between 9-14 years old. It was rare in 1-5 years old children. It had an abrupt onset, preceding infection/vaccination with no gender differences. Approximately 46.4% of cases had a recent upper respiratory tract illness. Varicella zoster virus infection, urinary tract infection, and mycoplasma pneumoniae were observed. Presentation signs included ataxia, decreased consciousness, fever plus nausea/vomiting, cranial nerve involvement, dysarthric speech, convulsion, hemiparesis, paresthesia, meningismus, and headache. We identified inflammation and demyelination in subcortical than periventricular lesions by magnetic resonance imaging. Prognosis was excellent with low mortality rate (6.6%). Acute disseminated encephalomyelitis is common in our children, possibly because of the high prevalence of causative infections. Due to advances in control of traditional exanthematous diseases such as measle, rubella and so forth, most cases of ADEM in this study followed non-specific upper respiratory infections. Differentiation of ADEM from a single episode of multiple sclerosis is difficult. Diagnosis of multiple sclerosis should be carried out

To determine the prevalence of neonatal dermatological findings and analyze whether there is an association between these findings and neonatal and pregnancy characteristics and seasonality. Newborns from three maternity hospitals in a Brazilian capital city were randomly selected to undergo dermatological assessment by dermatologists. 2938 neonates aged up to three days of life were randomly selected, of whom 309 were excluded due to Intensive Care Unit admission. Of the 2530 assessed neonates, 49.6% were Caucasians, 50.5% were males, 57.6% were born by vaginal delivery, and 92.5% of the mothers received prenatal care. Some dermatological finding was observed in 95.8% of neonates; of these, 88.6% had transient neonatal skin conditions, 42.6% had congenital birthmarks, 26.8% had some benign neonatal pustulosis, 2% had lesions secondary to trauma (including scratches), 0.5% had skin malformations, and 0.1% had an infectious disease. The most prevalent dermatological findings were: lanugo, which was observed in 38.9% of the newborns, sebaceous hyperplasia (35%), dermal melanocytosis (24.61%), skin desquamation (23.3%), erythema toxicum neonatorum (23%), salmon patch (20.4%), skin erythema (19%), genital hyperpigmentation (18.4%), eyelid edema (17.4%), milia (17.3%), genital hypertrophy (12%), and skin xerosis (10.9%). Dermatological findings are frequent during the first days of life and some of them characterize the newborn's skin. Mixed-race newborns and those whose mothers had some gestational risk factor had more dermatological findings. The gestational age, newborn's ethnicity, gender, Apgar at the first and fifth minutes of life, type of delivery, and seasonality influenced the presence of specific neonatal dermatological findings.

Full Text Available Background: Thirty-one cases of fever with rash were reported among students of a college in Pune, India, from March to May 2014. The clinical profile was similar to that of measles and 7 of them tested positive for measles-specific immunoglobulin M (IgM. An outbreak of measles was declared, and epidemiological investigation was carried out to assess the situation and suggest preventive measures. Methods: An epidemiological case sheet filled for each case to identify the source and likely contacts. Medical and administrative authorities were sensitized about the increase in incidence and clustering of cases. A surveillance system was set up for detection of new cases and follow-up of contacts. Throat swabs and blood samples from 12 cases were tested by ELISA method for commonly occurring viral exanthematous fevers to confirm the diagnosis and 7 were positive for measles-specific IgM antibody. Preventive measures were advised to control the outbreak. Results: A total of 31 cases of fever with rashes were reported among students of a college in Pune, India, during the months of March–May 2014. Most of the students were in the age group of 18–24 years. Samples from 12 cases were sent for testing and 7 tested positive for measles-specific IgM antibodies. Seven cases were epidemiologically linked to a lab-confirmed case. All cases had fever, maculopapular rash, and sore throat and gave a history of vaccination for measles in childhood. Conclusion: An epidemiological investigation was carried out for outbreak of measles in a young adult population of college students from Pune. It is reported that, with increase in overall coverage of vaccination, there is a rise in incidence of measles in vaccinated individuals. The age profile also shifts to higher age groups. Investigation of such outbreaks provides an opportunity to identify high-risk groups, changes in measles epidemiology and weaknesses in the routine immunization programs.

Full Text Available In 2015, Brazil was faced with the cocirculation of three arboviruses of major public health importance. The emergence of Zika virus (ZIKV presents new challenges to both clinicians and public health authorities. Overlapping clinical features between diseases caused by ZIKV, Dengue (DENV and Chikungunya (CHIKV and the lack of validated serological assays for ZIKV make accurate diagnosis difficult.The outpatient service for acute febrile illnesses in Fiocruz initiated a syndromic clinical observational study in 2007 to capture unusual presentations of DENV infections. In January 2015, an increase of cases with exanthematic disease was observed. Trained physicians evaluated the patients using a detailed case report form that included clinical assessment and laboratory investigations. The laboratory diagnostic algorithm included assays for detection of ZIKV, CHIKV and DENV. 364 suspected cases of Zika virus disease were identified based on clinical criteria between January and July 2015. Of these, 262 (71.9% were tested and 119 (45.4% were confirmed by the detection of ZIKV RNA. All of the samples with sequence information available clustered within the Asian genotype.This is the first report of a ZIKV outbreak in the state of Rio de Janeiro, based on a large number of suspected (n = 364 and laboratory confirmed cases (n = 119. We were able to demonstrate that ZIKV was circulating in Rio de Janeiro as early as January 2015. The peak of the outbreak was documented in May/June 2015. More than half of the patients reported headache, arthralgia, myalgia, non-purulent conjunctivitis, and lower back pain, consistent with the case definition of suspected ZIKV disease issued by the Pan American Health Organization (PAHO. However, fever, when present, was low-intensity and short-termed. In our opinion, pruritus, the second most common clinical sign presented by the confirmed cases, should be added to the PAHO case definition, while fever could be given less

Zika virus (ZIKV) is an arbovirus mainly transmitted to humans by mosquitoes from Aedes genus. Other ways of transmission include the perinatal and sexual routes, blood transfusion, and laboratory exposure. Although the first human cases were registered in 1952 in African countries, outbreaks were only reported since 2007, when entire Pacific islands were affected. In March 2015, the first cases of ZIKV acute infection were notified in Brazil and, to date, 48 countries and territories in the Americas have confirmed local mosquito-borne transmission of ZIKV. Until 2015, ZIKV infection was thought to only cause asymptomatic or mild exanthematous febrile infections. However, after explosive ZIKV outbreaks in Polynesia and Latin American countries, it was confirmed that ZIKV could also lead to Guillain-Barré syndrome and congenital birth abnormalities. These abnormalities, which can include neurologic, ophthalmologic, audiologic, and skeletal findings, are now considered congenital Zika syndrome (CZS). Brain abnormalities in CZS include cerebral calcifications, malformations of cortical development, ventriculomegaly, lissencephaly, hypoplasia of the cerebellum and brainstem. The ocular findings, which are present in up to 70% of infants with CZS, include iris coloboma, lens subluxation, cataract, congenital glaucoma, and especially posterior segment findings. Loss of retinal pigment epithelium, the presence of a thin choroid, a perivascular choroidal inflammatory infiltrate, and atrophic changes within the optic nerve were seen in histologic analyses of eyes from deceased fetuses. To date, there is no ZIKV licensed vaccines or antiviral therapies are available for treatment. Preventive measures include individual protection from mosquito bites, control of mosquito populations and the use of barriers measures such as condoms during sexual intercourse or sexual abstinence for couples either at risk or after confirmed infection. A literature review based on studies that

Systemic contact dermatitis is a condition that occurs when an individual sensitized to a contact allergen is exposed to that same allergen or a cross-reacting molecule through a systemic route. Systemic exposure to allergens can include transcutaneous, transmucosal, oral, intravenous, intramuscular, and inhalational routes. Baboon syndrome is perhaps the most recognizable form of systemic contact dermatitis, presenting with diffuse, well demarcated erythema of the buttocks, upper inner thighs, and axillae. Other forms of systemic contact dermatitis include dermatitis at sites of previous exposure to the allergen such as at a previous site of dermatitis or at sites of previous positive patch tests, dyshidrotic hand eczema, flexural dermatitis, exanthematous rash, erythroderma, and vasculitis-like lesions. The most common causes of systemic contact dermatitis consist of three groups of allergens: (i) metals including mercury, nickel, and gold; (ii) medications including aminoglycoside antibacterials, corticosteroids, and aminophylline; and (iii) plants and herbal products including the Compositae and Anacardiaceae plant families and Balsam of Peru. Baboon syndrome caused by systemic medications without a known history of previous cutaneous sensitization in the patient has been termed drug-related baboon syndrome (DRBS) or symmetric drug-related intertriginous and flexural exanthema (SDRIFE). Criteria for SDRIFE include exposure to systemic drug at first or repeated dose, erythema of the gluteal/perianal area and/or V-shaped erythema of the inguinal area, involvement of at least one other intertriginous localization, symmetry of affected areas, and absence of systemic toxicity. The most common causes are aminopenicillins, β-lactam antibacterials, and certain chemotherapeutic agents, though the list of etiologic agents continues to grow. Baboon syndrome and SDRIFE should be strongly considered in a patient presenting with a symmetric intertriginous eruption involving

Full Text Available Cases of vesicular and exanthematic disease by Vaccinia virus (VACV have been reported in dairy herds of several Brazilian regions, occasionally also affecting humans. The present article describes eight outbreaks of vesicular disease caused by VACV in dairy herds of six counties of Goiás state, Midwestern Brazil (2010-2012, involving a total of 122 cows, 12 calves and 11 people. Dairy cows (3 to 9 years old were affected in all cases and calves (2 to 9 months old were affected in five outbreaks, presenting oral lesions. The morbidity ranged between 8 and 100% in cows, and 1.5 to 31% in calves. In the cows, the clinical signs started with vesicles (2-7mm, painful and coalescent papules (3-8 mm, which resulted in ulcers (5-25mm and scabs in teats, and, occasionally, in the muzzle. The clinical course lasted from 16 to 26 days. The histopathology of bovine skin samples revealed superficial perivascular inflammatory infiltrate of lymphocytes, plasma cells, neutrophils, macrophages and multifocal areas of acanthosis, spongiosis, hipergranulosis and parakeratotic or orthokeratotic hyperkeratosis with adjacent focally extensive ulcers. Eosinophilic inclusion bodies were noted in the cytoplasm of the keratinocytes. PCR to vgf gene of Orthopoxvirus was positive in samples collected from all outbreaks, and in some cases, genomic VACV sequences were identified by nucleotide sequencing of the PCR amplicons. Infectious virus was isolated in cell culture from scabs from one outbreak. Antibodies to Orthopoxvirus were detected in at least 3 or 4 animals in most outbreaks, by ELISA (outbreaks 1, 2, 3, 4, 5 and 7 or virus-neutralization (outbreak 6. Neutralizing titers ranging from 8 to 64 in outbreak 6. In all outbreaks, VACV infection was suspected based on the clinical and pathological findings and it was confirmed by laboratory tests. Upon the etiological confirmation, other agents associated with vesicular disease were discarded. In all outbreaks, at least

Antiphospholipid Syndrome with Antiβ2glicoprotein-1 Antibodies as the Cause of Recurrent Tibial Vein Thrombosis in SAPHO syndrome.

Przepiera-Będzak, Hanna; Brzosko, Marek

2016-12-01

The antiphospholipid antibody syndrome is defined by the presence of antiphospholipid antibodies in patients with recurrent venous or arterial thromboembolism (1). SAPHO syndrome is a rare disease, characterized by specific clinical manifestations of synovitis, acne pustulosis, hyperostosis, and osteitis. It is a disease that manifests with a combination of osseous and articular manifestations associated with skin lesions (2). Venous thrombosis complicating SAPHO syndrome seems to be uncommon with an unclear pathogenesis (3-9). Coexistence of antiphospholipid syndrome and SAPHO syndrome was not previously mentioned in literature. A 33-year-old white woman was diagnosed with SAPHO syndrome at the age of 31. The patient was previously diagnosed with polycystic ovary syndrome and depressive syndrome. She was treated with sulfasalazin (2 g daily) and methotrexate (20 mg weekly). Seven months before admission to our department she experienced an episode of deep vein thrombosis of the left leg, successfully treated with subcutaneous enoxaparin sodium (40 mg daily) that was continued for the following 6 months as secondary prophylaxis. Pustular skin changes on palmar surface of the hands and plantar surface of the feet (characteristic for palmo-plantar pustulosis), tenderness of sterno-clavicular joints, swelling and restricted motion of both wrists, and pain on motion in both elbows, shoulders, knees, and ankles were found on physical examination. There was also a moderate amount of effusion in her left knee. There was a 3-centimeter difference between the circumferences of the shins. The level of C reactive protein was increased (6.21 mg/L). The patient was positive for antiβ2glicoprotein-1 (anti-β2G-1) antibodies. Tests for anticardiolipin antibodies (aCL), antiannexin V antibodies, antiphosphatidylserine antibodies (aPS), and antiprothrombin antibodies (aPT) were negative. Prothrombin time, activated partial thromboplastin time, and D-dimer level were normal, and

Abstract Background Human Parvovirus B19 (HPV-B19) occurs worldwide and causes mild, acute exanthematous disease that occurs in a form of cyclic local epidemics. The aim of this study was to analyze clinical features and complication rates of acute HPV-B19 infection in different age groups. Methods We retrospectively reviewed the charts of 718 consecutive patients clinicaly diagnosed with acute HPV-B19 infection who visited outpatient department at the University Hospital for Infectious Diseases in Zagreb, Croatia during 2013–2014 outbreak. In 212 patients (of 298 tested) diagnosis was confirmed by positive IgM antibodies and/or HPV-B19 DNA in peripheral blood. Results Outbreak started in June 2013 and had a peak in April 2014, with highest prevalence in schoolchildren. There were no difference in clinical presentation or laboratory findings between clinicaly and serologicaly diagnosed patients. Biphasic presentation, fever, myalgia, arthralgia, headache and peripheral edema were more frequent in adults, but „slapped cheeks” was found predominantly in children. Complications were more common in adults, most commonly hematological disordes (mild anemia, thrombocytopenia and leukopenia), vasculitis, hepatitis and aseptic meningitis. There were no deaths in our cohort. Children

As in the cases, in which it was possible to examine the mothers of those children, these women were of a healthy appearance, the conclusion was drawn that the disease, although extremely severe and fatal, can present an unapparent form. In 2 cases, serum protection tests proved such an unapparent infection of the mothers, in whom neutralizing antibodies against Toxoplasma were met with (Paige, Cowen & Wolf. Although no detailed microscopical study has been made in all cases, the disease is characterized by granulomatous meningoencephalomyelitis (Wolf & Cowen, often associated with myocarditis and chorioretinitis. The symptoms presented by the patients were: fever, convulsions, respiratory disturbances, hydrocephalus, cyanosis, vomiting, temperature lability, etc., the diagnostic sign of the greatest importance being the presence of foci of profound cerebral calcification and chorioretinitis in new born (Wolf, Cowen & Paige.

The remaining three cases were described in adults; in one of them the changes were not typical (these was a concomittant infection by Bartonella bacilliformis and in the two others the disease assumed an "exanthematous form", simulating a macular fever (Pinkerton & Henderson, the most important microscopical evidence being an interstitial pneumonia. Apart from the clinical similarity, also the encephalitis foci met with in this "exanthematous form" of toxoplasmosis resemble those described in "macular fevers"…

.4 sanctions per game in the 21 years-old category. Significant differences emerged among players in the different categories for behaviours such as fault to gain possession of the ball, discussing the referee´s decisions, holding and opponent, or delaying the restart of play. There were no sanctions for those behaviours in the lower categories, increasing their numbers from the 11-12 years-old category until the higher competitive levels. Other behaviours, such as making contact with the opponent before touching the ball, striking or threatening an opponent, and offensive or insulting language directed to the referee or to an opponent, first appeared in the 13-14 years-old players, but number of sanctions remained low and similar in the different competitive levels. Our data confirm that playing experience may be an important determinant of antisocial behaviours. However, the various types work differently, and are instrumental behaviours those that clearly increase as a function of competitive level.

clinical presentation in all patients was pain in the upper anterior chest wall for at least four months. Imaging findings of all these patients indicated inflammatory process and/or hyperostosis and osteitis in the joints of the upper anterior chest wall. Skin manifestations of the syndrome, such as palmoplantar pustulosis, were identified in five of the patients. In none of the cases the diagnosis was suggested either at the initial clinical medical appointment or after imaging assessment by radiologists not specialized in musculoskeletal system. CONCLUSION: Our clinical and imaging findings are in line with the ones described in the literature. This diagnosis must be considered for each patient presenting with pain in the upper anterior chest wall associated with skin lesions and/or osteitis.

as well as to investigate the role of viral pathogens in the etiology of GCS cases from Belem (PA, Brazil. PATIENTS AND METHODS: From August 1996 to December 2002, ten children with a clinical diagnosis of GCS were investigated through routine laboratory exams and serologically screened for several virus specific antibodies. A diagnosis of GCS was considered for cases that presented clinical aspects considered suggestive, together with one or more of the following criteria: elevated titers of hepatic enzymes, lymphocytosis, positive viral serology or history of a prior vaccination. RESULTS: Six out of 10 children (60% showed evidence of HHV6 primary infection, as demonstrated through specific IgM-antibody positivity. CONCLUSION: Anti-HHV6-IgM antibody positivity in 6/10 patients suggests that the pathogen can play a role in the etiology of GCS. Consequently, the authors recommend that this virus is added to the routine serological tests when exanthematous processes are concerned, especially those with a morphology suggestive of GCS.

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

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

The early lesions (twelve to thirty-six hours in the epidermis show usually different stages in a single slide examined. They are described as minute vesicles and pustules; in older lesions the pustules have dried up forming thickened plaques in and beneath cornified layer. Parakeratotic cells with intranuclear bodies first described by TORRES & TEIXIERA (1932 b while inconstant are regarded as a pathognomonic change in measles eruption. Edema of the papillary layer and perivascular infiltrations in the reticular layer by large mononuclears some of them containing small irregular deeply stained granules (MALLORY-MEDLAR-LIPSCHÜTZ' cells are well known changes largely referred in the literature. Evidence is here submitted in support of the opinion that such cells correspond to macrophages with keratohyaline granules phagocited as a consequence of changes in cornification determined by the virus itself. Microscopic examination is necessary for the demonstration of the minute vesicles and pustules which are such an important detail in the histology of the measles eruption as it establishes connections between measles usually considered in the group of exanthematous diseases with chicken-pox, zoster, small-pox and alastrim (pustulous diseases. Epidermal changes are no more found seventy-two hours after the onset of the eruption while well-defined mantles of cells about the vessels and a moderate proliferation of fibrocytes is noticed in the corium.

After the children had had their details taken and entered on the study protocol, they were subjected to physical examination followed by collection of blood samples for blood testing with platelet counts and serology (IgM and IgG; initially for dengue, rubella and toxoplasmosis and then, in negative cases, serology was also run for parvovirus, herpes virus type 6 and measles. RESULTS: Laboratory diagnoses were confirmed by means of IgM antibody assay in 88.7% of the cases investigated: dengue (77.5%, herpes virus type 6 (8.4%, parvovirus (2.8% and in eight patients diagnosis was inconclusive (11.3%. On this occasion no positive serology (IgM was observed for measles, rubella or toxoplasmosis. The most common clinical manifestations among the dengue patients were: fever, itching, prostration, myalgia and positive tourniquet test results. In 58.4% (32/55 of those cases diagnosed with dengue, the tourniquet test was positive, which was a statistically significant difference when compared with the remainder of the sample. CONCLUSIONS: When children present with exanthema, it is possible that dengue is the primary causative disease, depending on the epidemiology of the location. Constant control of epidemiological and serological surveillance of exanthematous diseases is necessary.

Methods: Newborns from three maternity hospitals in a Brazilian capital city were randomly selected to undergo dermatological assessment by dermatologists. Results: 2938 neonates aged up to three days of life were randomly selected, of whom 309 were excluded due to Intensive Care Unit admission. Of the 2530 assessed neonates, 49.6% were Caucasians, 50.5% were males, 57.6% were born by vaginal delivery, and 92.5% of the mothers received prenatal care. Some dermatological finding was observed in 95.8% of neonates; of these, 88.6% had transient neonatal skin conditions, 42.6% had congenital birthmarks, 26.8% had some benign neonatal pustulosis, 2% had lesions secondary to trauma (including scratches, 0.5% had skin malformations, and 0.1% had an infectious disease. The most prevalent dermatological findings were: lanugo, which was observed in 38.9% of the newborns, sebaceous hyperplasia (35%, dermal melanocytosis (24.61%, skin desquamation (23.3%, erythema toxicum neonatorum (23%, salmon patch (20.4%, skin erythema (19%, genital hyperpigmentation (18.4%, eyelid edema (17.4%, milia (17.3%, genital hypertrophy (12%, and skin xerosis (10.9%. Conclusions: Dermatological findings are frequent during the first days of life and some of them characterize the newborn's skin. Mixed-race newborns and those whose mothers had some gestational risk factor had more dermatological findings. The gestational age, newborn's ethnicity, gender, Apgar at the first and fifth minutes of life, type of delivery, and seasonality influenced the presence of specific neonatal dermatological findings. Resumo: Objetivo: Verificar a prevalência dos achados dermatológicos nos primeiros dias de vida e analisar se há associação com características neonatais, gestacionais e

Parkinson´s is a common disease (PD caused by degeneration of dopaminergic neurons in the substantia nigra and other brain areas. Several genes and mutations have been mplicated in its pathogenesis, the latter have been identified mainly in the PARK2 gene.

We report the evaluation of this gene and of its flanking region in a large family from the southwestern part of Colombia. The parents are first cousins and four out of their ten children were affected at juvenile age.>
