The primary contributing factors in contracting scabies seem to be poverty and overcrowded living conditions. Scabies often spreads among schoolchildren quite rapidly, owing to their close contact and overcrowding within the schools. However, limited information is available about its risk factors and the socioeconomic correlates among schoolchildren in Egypt. This study aimed to assess the prevalence of scabies and its risk factors among primary schoolchildren in Kafr El-Sheikh administrative area, Egypt. Methods: This cross-sectional descriptive study was performed on primary schoolchildren in urban and rural areas of Kafr El-Sheikh administrative area. A predesigned questionnaire was used for data collection from the randomly selected 2,104 children, and clinical dermatological examination was done for them. Results: Out of 2,104 children studied, there were 92 cases of scabies with a prevalence of 4.4%. The prevalence of scabies infestation in male students was 3.9%, while it was 4.8% in females, with no statistical significance. The results showed significant variations in the risk of scabies infestation by factors such as residence, paternal education and occupation, maternal education, sleeping with others, having animals at home, dealing with animals outside the house, type of building for living, family history of itchy rash, and sharing clothes with others. Conclusion: In our community, scabies is still an important health problem affecting schoolchildren, especially in rural areas. It is characterized by a complex web of causation, particularly poor

Impetigo and scabies both present different challenges in resource-limited compared with industrialised settings. Severe complications of these skin infections are common in resource-limited settings, where the burden of disease is highest. The microbiology, risk factors for disease, diagnostic approaches and availability and suitability of therapies also vary according to setting. Taking this into account we aim to summarise recent data on the epidemiology of impetigo and scabies and describe the current evidence around approaches to individual and community based treatment.

Several sources suggest an escalation of scabies in France. To describe a population of patients continuing to present with scabies despite multiple treatments in order to identify factors associated with persistence of infection. A descriptive cross-sectional study in adults and children consulting for persistent scabies despite at least one previous treatment. A standardized questionnaire explored potential sources of treatment failure. Thirty-one patients were analyzed. Initial symptoms were noted to have started between two and 52 weeks earlier (mean: 19 weeks). The mean number of prior consultations with a general practitioner was 3.1 (0-10) and 1.7 with a dermatologist (0-7). The mean number of patients per household was 3.5 (1-9). At least one dose of oral ivermectin (maximum of 6 doses per household) was prescribed for 84 % of patients (29 % of whom were not fasted at the time). Further, 74 % of patients received at least one local application of esdepallethrin and piperonyl butoxide (maximum: 5 courses), four received benzyl benzoate and two received permethrin; however, 58 % did not reapply the substance after hand washing. All households bought the prescribed treatments despite the costs. Close contacts of patients were treated in 58 % of households. Decontamination of bedding and clothing was carried out properly in 90 % of households. Persistence of infection appears to be linked to: (1) insufficient treatment of close contacts; (2) absence of a second treatment between days 7 and 14; (3) insufficient efficacy of the available treatments, doubtless due to multiple factors (intrinsic resistance of Sarcoptes, failure to repeat treatment, poor explanation of methods for dosing and application, and oral intake of treatments). Access to non-reimbursed treatments was not identified as a problem and decontamination of bedding and clothing was correctly performed in most cases. Though certain fundamental aspects of scabies treatment must be better

Scabies Mites Alter the Skin Microbiome and Promote Growth of Opportunistic Pathogens in a Porcine Model

Background The resident skin microbiota plays an important role in restricting pathogenic bacteria, thereby protecting the host. Scabies mites (Sarcoptes scabiei) are thought to promote bacterial infections by breaching the skin barrier and excreting molecules that inhibit host innate immune responses. Epidemiological studies in humans confirm increased incidence of impetigo, generally caused by Staphylococcus aureus and Streptococcus pyogenes, secondary to the epidermal infestation with the parasitic mite. It is therefore possible that mite infestation could alter the healthy skin microbiota making way for the opportunistic pathogens. A longitudinal study to test this hypothesis in humans is near impossible due to ethical reasons. In a porcine model we generated scabies infestations closely resembling the disease manifestation in humans and investigated the scabies associated changes in the skin microbiota over the course of a mite infestation. Methodology/Principal Findings In a 21 week trial, skin scrapings were collected from pigs infected with S. scabies var. suis and scabies-free control animals. A total of 96 skin scrapings were collected before, during infection and after acaricide treatment, and analyzed by bacterial 16S rDNA tag-encoded FLX-titanium amplicon pyrosequencing. We found significant changes in the epidermal microbiota, in particular a dramatic increase in Staphylococcus correlating with the onset of mite infestation in animals challenged with scabies mites. This increase persisted beyond treatment from mite infection and healing of skin. Furthermore, the staphylococci population shifted from the commensal S. hominis on the healthy skin prior to scabies mite challenge to S. chromogenes, which is increasingly recognized as being pathogenic, coinciding with scabies infection in pigs. In contrast, all animals in the scabies-free cohort remained relatively free of Staphylococcus throughout the trial. Conclusions/Significance This is the first

One hundred and twenty scabietic patients attending the outpatient clinic of the Department of Dermatology, Mansoura University Hospital, voluntarily participated in this uncontrolled, open label study to evaluate ivermectin 20 microg/kg as a scabietic after they had given their consent. The scabietic subjects included in this study were otherwise healthy, mentally competent, aged more than 18 years, and used no topical antiscabietic treatment in the week before ivermectin treatment, or during the 4-week study period. Patients were also required to show clinical evidence of scabies, and the microscopically demonstrated presence of Sarcoptes scabiei, their eggs, or their fecal pellets (scybala). A thorough history was taken, and a physical examination was conducted that included measurement of the pulse, blood pressure, temperature, and weight. For each participant, the distribution of scabies lesions was plotted on a body diagram, and the severity of disease was recorded as mild (10 or fewer lesions), moderate (11-49 lesions), or severe (50 or more lesions). Skin scrapings were examined for mites, eggs, or scybala. Urinalysis, stool analysis, a complete blood count, prothrombin time, and serum chemistry studies (serum creatinine, alanine aminotransferase (ALT), and total bilirubin) were performed before treatment, and 2 and 4 weeks after the drug was given. Ivermectin was administered as scored 6-mg tablets with water, and the dose was designed to provide 200 micrograms/kg (ivermectin was provided by Delta Pharma, Tenth of Ramadan City, Egypt). The patients were instructed to have recently worn clothing, sheets, and towels washed in a hot cycle the day after treatment. The patients were interviewed 3 days after treatment about any symptoms or subjective evidence of adverse reactions. Follow-up examinations were carried out 2 and 4 weeks after intake of ivermectin, and all examination procedures and laboratory investigations were repeated. Cure criteria included

Scabies and associated impetigo are under-recognized causes of morbidity in many developing countries. To strengthen the evidence base for scabies control we undertook a trial of mass treatment for scabies. We report on the occurrence and predictors of scabies and impetigo in participants at baseline. Participants were recruited in six island communities and were examined for the presence of scabies and impetigo. In addition to descriptive analyses, logistic regression models were fit to assess the association between demographic variables and outcome of interest. The study enrolled 2051 participants. Scabies prevalence was 36.4% (95% confidence interval [CI] 34.3-38.5), highest in children 5-9 years (55.7%). Impetigo prevalence was 23.4% (95% CI 21.5-25.2) highest in children aged 10-14 (39.0%). People with scabies were 2.8× more likely to have impetigo. The population attributable risk of scabies as a cause of impetigo was 36.3% and 71.0% in children aged less than five years. Households with four or more people sharing the same room were more likely to have scabies and impetigo (odds ratios [OR] 1.6, 95% CI 1.2-2.2 and OR 2.3, 95% CI 1.6-3.2 respectively) compared to households with rooms occupied by a single individual. This study confirms the high burden of scabies and impetigo in Fiji and the association between these two conditions, particularly in young children. Overcrowding, young age, and clinical distribution of lesion are important risk factors for scabies and impetigo. Further studies are needed to investigate whether the decline of endemic scabies would translate into a definite reduction of the burden of associated complications.

The scabies mite, Sarcoptes scabiei, is a parasitic arachnid and cause of the infectious skin disease scabies in humans and mange in other animal species. Scabies infections are a major health problem, particularly in remote Indigenous communities in Australia, where secondary group A streptococcal and Staphylococcus aureus infections of scabies sores are thought to drive the high rate of rheumatic heart disease and chronic kidney disease. We sequenced the genome of two samples of Sarcoptes scabiei var. hominis obtained from unrelated patients with crusted scabies located in different parts of northern Australia using the Illumina HiSeq. We also sequenced samples of Sarcoptes scabiei var. suis from a pig model. Because of the small size of the scabies mite, these data are derived from pools of thousands of mites and are metagenomic, including host and microbiome DNA. We performed cleaning and de novo assembly and present Sarcoptes scabiei var. hominis and var. suis draft reference genomes. We have constructed a preliminary annotation of this reference comprising 13,226 putative coding sequences based on sequence similarity to known proteins. We have developed extensive genomic resources for the scabies mite, including reference genomes and a preliminary annotation.

Four new cases of sarcoptic mange in cats are described. Two cats resided in areas known to be frequented by foxes, another cohabited with a dog recently diagnosed with sarcoptic mange, while the final cat lived with a mixed breed dog that had been treated for sarcoptic mange 7 months previously. Three cases were diagnosed on the basis of characteristic mite size and morphology in skin scraping from representative lesions, situated on the head (two cases) or head and distal hind limbs (one case). Mites were highly mobile and abundant in all instances, and easily detected also in skin biopsy specimens procured from two cases. Eosinophilic inflammation, hyperkeratosis and parakeratosis were prominent in the tissue sections. In the remaining case, the diagnosis was presumptive, based on characteristic lesions, cohabitation with a canine scabies patient and positive response to scabicide therapy. Pruritus was not a prominent clinical feature in any patient and was considered to be absent in three of the four cases. Lesions in three cats with long-standing disease were reminiscent of crusted scabies (synonym: Norwegian scabies, parakeratotic scabies) as seen in human patients. In three cases, in-contact human carriers developed itchy cutaneous papular lesions. Two cases responded promptly to therapy with systemic avermectin drugs, while one responded to topical treatment with lime sulphur and the remaining cat received both a lime sulphur rinse and ivermectin. Sarcoptic mange should be considered in the differential diagnosis of cats with non-pruritic crusting skin diseases, especially when there is contact with foxes or dogs, and when owners have itchy papular lesions.

Full Text Available Background: Scabies is caused by infestation and sensitization of Sarcoptess cabiei and is an endemic in tropical and subtropical regions around the world. Several factors in the disease transmission are overcrowded living conditions, poor personal hygiene, unhealthy behaviors and population density. Pesantren is a spesific name for an educational Islamic institution in Indonesia and which w could be one of the risk factors of the transmission the disease. Most of the students (santri are staying at the institution for a long time. The objective of this study was to know the level of knowledge, attitude and practice of santri in preventing scabies. Methods: A descriptive study was conducted on 45 santri in Pesantren Darul Fatwa in Jatinangor during September–December 2012. A questionnaire was set up consisting of questions about age, sex, basic knowledge, attitude, and practice of preventing the transmission of scabies. Data were analyzed using frequency distribution. Results: The level of knowledge and attitude of the respondents to prevent the transmission of scabies were good, meanwhile the level of practice was moderate. There were still questions that could not be answer by the respondents those were the etiology (31.1%, the cut off chain of transmission (40%, and how to prevent scabies (37.8%. Not washing the towel, changing the bed linen and pillow case every 2 weeks were the less good practice performed by the respondents. Conclusions: The knowledge and attitude towards the prevention of transmission of scabies are good while the practices are moderate. A further study with more sample size should be carried out including enviromental assessment.

Streptomyces scabies is a common soil bacterium that causes scab symptoms in potatoes. Strong evidence indicates horizontal gene transfer (HGT) among bacteria has influenced the evolution of this plant pathogen and other Streptomyces spp. To extend the study of the HGT to the Streptomyces genus, we explored the effects of the inter-domain HGT in the S. scabies genome. We employed a semi-automatic pipeline based on BLASTp searches and phylogenetic reconstruction. The data show low impact of inter-domain HGT in the S. scabies genome; however, we found a putative plant pathogenesis related 1 (PR1) sequence in the genome of S. scabies and other species of the genus. It is possible that this gene could be used by S. scabies to out-compete other soil organisms. Copyright © 2016 Elsevier Inc. All rights reserved.

Simple method of detecting sarcoptes scabiei var hominis mites among bedridden elderly patients suffering from severe scabies infestation using an adhesive-tape.

Scabies infestation is very common among bedridden elderly patients. The standard method of diagnosis for scabies by scraping the skin requires some skill. Therefore, dermatologists employ this method. However, dermatologists are usually not present in most long-term nursing units. Thus, we tried to catch mites using a strong transparent adhesive tape commercially available for packing use as an alternative method for the diagnosis of severe scabies infestation. After firmly applying the adhesive side of the tape onto an appropriate skin lesion of patients, the tape was pulled off and transferred directly onto a slide for microscopy, affixing the adhered separated part of the corneal skin. When a massive outbreak of scabies infestation occurred in May 2004 at the nursing unit of K hospital with thirty-one bedridden elderly patients, we tried to detect scabies mite using an adhesive tape. We could detect mites from six patients using this tape method. The diagnosis was confirmed by the standard scraping method. By the tape method we could observe some mites moving around and also could see a striated structure with dark red or weak red color or gray color granule-like constitution on the body of some mites. We found mites only on the skin of the fingers and toes where the skin of a patient is thin. Recently, massive scabies infestation in elderly long-term residents has been reported elsewhere. This tape method is simple and useful for diagnosis of severe scabies infestation in long-term nursing units.

A widespread scabies infestation, associated to long-term residence in nursing homes, is becoming a serious issue in developed countries. Mineral oil examination is regarded as the gold standard in diagnosing scabies, but the sensitivity of this method is generally low-approximately 50%. Molecular tests may contribute to enhance the sensitivity of current tests for laboratory diagnosis of human scabies. In this study, we developed new primers for a nested PCR for the cytochrome c oxidase subunit 1 (cox1) gene of Sarcoptes scabiei var. hominis to increase the sensitivity of a previously developed conventional PCR. Clinically suspected scabies patients underwent dermoscopy-guided skin scraping with microscopic examination. The diagnosis was positive for scabies when mites or eggs were found under the microscope, and patients were then designated as 'microscopy-positive'. Patients in the 'microscopy-negative' group presented with negative microscopic results. Skin scrapings were collected from both groups for PCR. Of the total 63 samples, 28 were microscopy-positive and 35 were negative with no differences in sex and age between the two groups. All microscopically proven scabies cases were positive with the cox1 nested PCR. Among microscopy-negative ones, S. scabiei DNA was detected in 9 samples. If sensitivity of the cox1 nested PCR is considered 100% (95% CI, 90.51-100), then sensitivity of microscopy is 75.68% (95% CI, 58.80-88.23; P = 0.004). Nested PCR can be successfully used as an alternative method for diagnosing suspected scabies patient. Therefore, infection control measures and treatments can be initiated before significant transmission occurs, minimizing the risk of outbreaks. This article is protected by copyright.

The dire lack of information concerning the epidemiology of human scabies in Cameroon, especially in school milieus brought us to undertake the present study which aimed to determine the prevalence and associated factors of scabies in Cameroonian boarding schools. A cross-sectional study was conducted from February to March 2015 in four boarding schools in Yaoundé and Buea (Cameroon). Participants were students currently residing in one of the study sites, volunteering to participate in the study and whose parents or guardians had given their consent in this respect. The diagnosis was based on clinical assessment independently performed by two dermatologists. A total of 1,902 students were recruited (50.5 % boys), with a mean age of 14.3 ± 2.5 years. Overall, 338 participants (17.8 %) were diagnosed with scabies. Age ≤ 15 years, male sex, number of students in the school > 500, no access to the school infirmary, sleeping with others, sharing beddings, clothes or toilet stuffs, pruritus in the close entourage and complaining of pruritus were significantly associated with the presence of mites in univariable logistic regression analyses. On the other hand, at least two baths per day, usage of soap for baths and finger nails always cut short appeared as protective factors. After multivariable analysis, male sex (adjusted OR (aOR) 2.06, 95 % CI: 1.40-3.01, P < 0.0001), first cycle level of education (aOR 1.67, 95 % CI: 1.02-2.71, P = 0.040), number of students per dormitory ≤ 10 (aOR 6.99, 95 % CI: 3.34-14.71, P < 0.0001), no access to the school infirmary (aOR 1.62, 95 % CI: 1.12-2.32, P = 0.009) and complaining of pruritus (aOR 93.37, 95 % CI: 60.04-145.19, P < 0.0001) were the independent factors associated with scabies. The prevalence of scabies was 17.8 %. The male sex, first cycle level of education, a number of students per dormitory ≤ 10, no access to the school infirmary and complaining of pruritus were

The study presents the comparative analysis of scabies and STI incidence in different groups of population in Saratov region from 1991 till 2010. Principal causes and factors supporting epidemic process of infectious diseases in this region on an extent of 2 decades are revealed. It is established that if the basic group patients with scabies were children, teenagers and people at the age from 20 to 29 years, so, in the group with STI there were patients aged from 18 to 29 years. Besides, it was proved that over the last years early and late latent forms of syphilis and neurosyphilis prevail among patients in age group from 40 to 60 years. It leads to disability, and sometimes invalidism quite often.

Full Text Available Background Scabies is one of the most common itching contagious skin disorder in the world. The agent of disease is Sarcoptes scabiei. Objectives This study was conducted to determine the frequency and clinical manifestations of S. scabies in suspected patients referred to health centers of Kashan during 2010 - 2014. Methods This cross-sectional study was performed on 129 patients suspected to Sarcoptes scabiei. The demographic and clinical symptoms for each of patients were recorded in questionnaire by interview. A deep skin scrap was prepared and wet smear were prepared using 10% KOH. By observation of each form of Sarcoptes was identified as positive sample. The data were recorded in Spss. ver 16.5 and analyzed by X2 and fisher exact tests. Results The results of this study showed that 28 (21.7 % were Sarcoptes positive. The frequency of sarcoptes was higher in males (23% than females (20.6%. The difference was not statistically significant. The most cases were isolated in spring and winter. Sarcoptes infestation was the most in elderly and patients undergone dialysis. There is significant difference between disease and age group and underlying disease (P = 0.03, P = 0.014; respectively. Erosion or pustule was the most clinical signs in positive cases. Conclusions The results of study showed that the rate of scabies infestation in Kashan is relatively high, and the most cases were in elderly patients. Health education to increase awareness of the families for prevention of scabies was recommended.

Full Text Available Abstract Background Although senile dementia patients in long-term care facilities are at leading risk of scabies, the epidemiologic characteristics of this disease have yet to be fully clarified. This study documents the findings of a ward-scale nosocomial outbreak in western Japan from 1989–90, for which permission to publish was only recently obtained. Methods A retrospective epidemiologic study was performed to identify specific risk factors of scabies among patients with dementia. Analyses were based on a review of medical and nursing records. All inpatients in the affected ward at the time of the outbreak were included in the study. Observational and analytical approaches were employed to assess the findings. Results Twenty of 65 inpatients in the ward met the case definition of scabies. The outbreak lasted for almost 10 months and as a result, the spatial distribution of infections showed no localized patterns in the latter phase of the outbreak. The duration of illness significantly decreased after initiation of control measures (P = 0.0067. Movement without assistance (Odds Ratio [OR] = 11.3; 95% Confidence Interval [CI]: 2.9, 44.8 and moving beyond the room (but within the ward (OR = 4.1; 95% CI: 1.4, 12.5 were significantly associated with infection, while types of room (Western or Japanese and sleeping arrangement (on beds or futons laid directly on the floor appeared not to be risk factors. Conclusion Univariate analysis demonstrated the importance of patients' behaviours during daily activities in controlling scabies among senile dementia patients. The findings also support previous evidence that catching scabies from fomites is far less common. Moreover, since cognitive disorders make it difficult for individuals to communicate and understand the implications of risky contacts as well as treatment method, and given the non-specific nature of individual contacts that are often unpredictable, real-time observations might help

The aim of this study was to develop and validate a HybProbes-based real-time PCR assay targeting the trpB gene for specific identification of Streptomyces scabies and Streptomyces europaeiscabiei. Four primer pairs and a fluorescent probe were designed and evaluated for specificity in identifying S. scabies and Streptomyces europaeiscabiei, the potato common scab pathogens. The specificity of the HybProbes-based real-time PCR assay was evaluated using 46 bacterial strains, 23 Streptomyces strains and 23 non-Streptomyces bacterial species. Specific and strong fluorescence signals were detected from all nine strains of S. scabies and Streptomyces europaeiscabiei. No fluorescence signal was detected from 14 strains of other Streptomyces species and all non-Streptomyces strains. The identification was corroborated by the melting curve analysis that was performed immediately after the amplification step. Eight of the nine S. scabies and S. europaeiscabiei strains exhibited a unique melting peak, at Tm of 69·1°C while one strain, Warba-6, had a melt peak at Tm of 65·4°C. This difference in Tm peaks could be attributed to a guanine to cytosine mutation in strain Warba-6 at the region spanning the donor HybProbe. The reported HybProbes assay provides a more specific tool for accurate identification of S. scabies and S. europaeiscabiei strains. This study reports a novel assay based on HybProbes chemistry for rapid and accurate identification of the potato common scab pathogens. Since the HybProbes chemistry requires two probes for positive identification, the assay is considered to be more specific than conventional PCR or TaqMan real-time PCR. The developed assay would be a useful tool with great potential in early diagnosis and detection of common scab pathogens of potatoes in infected plants or for surveillance of potatoes grown in soil environment. © 2015 Her Majesty the Queen in Right of Canada © 2015 The Society for Applied Microbiology.

Implementing systems thinking for infection prevention: The cessation of repeated scabies outbreaks in a respiratory care ward.

Chuang, Sheuwen; Howley, Peter P; Lin, Shih-Hua

Root cause analysis (RCA) is often adopted to complement epidemiologic investigation for outbreaks and infection-related adverse events in hospitals; however, RCA has been argued to have limited effectiveness in preventing such events. We describe how an innovative systems analysis approach halted repeated scabies outbreaks, and highlight the importance of systems thinking for outbreaks analysis and sustaining effective infection prevention and control. Following RCA for a third successive outbreak of scabies over a 17-month period in a 60-bed respiratory care ward of a Taiwan hospital, a systems-oriented event analysis (SOEA) model was used to reanalyze the outbreak. Both approaches and the recommendations were compared. No nosocomial scabies have been reported for more than 1975 days since implementation of the SOEA. Previous intervals between seeming eradication and repeat outbreaks following RCA were 270 days and 180 days. Achieving a sustainable positive resolution relied on applying systems thinking and the holistic analysis of the system, not merely looking for root causes of events. To improve the effectiveness of outbreaks analysis and infection control, an emphasis on systems thinking is critical, along with a practical approach to ensure its effective implementation. The SOEA model provides the necessary framework and is a viable complementary approach, or alternative, to RCA.

Outbreaks of scabies in institutions and the socio-economic consequences have not been reported from overpopulated countries such as Bangladesh. A community-based study among children from six residential Islamic education institutes (madrashas) in Dhaka. Multistage random sampling was used. To study the socio-economic profile, water-sanitation facilities, personal hygiene and living conditions of these children. Direct interviews were used to collect the data and clinical check up was performed in all children. In total, 492 children received clinical check-ups; 92.5% were boys (mean age: 11.2+/-2.4 years). 63.4% of fathers and 98.5% of mothers were either illiterate or had only received primary education, 55.1% of fathers were in low-paid labouring jobs, and 99% of mothers were housewives. Of the 98% of children who had scabies, 71% had been re-infected (96% during the winter). Randomly assigned anti-scabies drugs revealed an average cure rate of 85.5%. Seventy-four percent of children were living in poorly ventilated buildings with overcrowded sleeping arrangements. They had poor personal hygiene: 21% shared towels; 8% shared undergarments; 30% shared bed linen; and 81% kept their used clothes on a communal line or shelf. Sanitation was also poor: 39% bathed infrequently, although 97% carried out mandatory ablution. Most children (61%) washed their clothes (including undergarments) two or three times a fortnight, 35% did so every 2-3 days, and 3.7% washed their clothes on alternative days. Disease severity and re-infection were associated with infrequent washing of clothes (P<0.001) and bed linen (P<0.001), overcrowded sleeping arrangements (P<0.001) and infrequent bathing (P<0.001) with soap (P<0.001). This was further related to household income (P<0.001 for both). The study findings have potentially dangerous implications for public health. Immediate attention should be given to developing a sustainable long-term intervention programme to combat scabies

A 19-year-old male was admitted to the medical ward with complaints of fever and swelling of the ankle and wrist joints of about two weeks duration. The patient developed hyperkeratotic lesions of the skin over the hands, elbow and back about three weeks after admission. Antistreptolysin O, rheumatoid factor, and Widal tests as well as Chickungunya, brucella, HIV and antinuclear antibodies were negative. Culture of blood sample and pus aspirate from the ankle and chest yielded a pure growth of Staphylococcus epidermidis. Potassium hydroxide (KOH) mount of the scrapings from crusted skin lesions showed plenty of adult mites, eggs and faecal pellets of Sarcoptes scabiei. A diagnosis of crusted scabies with secondary bacterial infection was made and the patient was treated successfully with oral ivermectin, topical permethrin and vancomycin.

Job of the Bible: leprosy or scabies?

Appelboom, Thierry; Cogan, Elie; Klastersky, Jean

2007-04-01

Proposing a medical diagnosis a posteriori of a person who died a long time ago is not as impossible as it sounds if sufficient medical history is available.A whole book of the Bible is devoted to Job and his trials. The diagnosis of leprosy has been generally accepted by medieval commentators because the verses of the Book speak of ulcers disseminated over the skin, and also because leprosy is an exemplary sanction imposed by way of example by God to punish those who have committed a sin. In this paper, we have taken the different verses with a medical content from the Book of Job, and reconstructed the clinical picture as if the patient had turned up in the 21st century in order to see if the diagnosis of leprosy may be called into question, and to discuss the limits of the medico-historic approach. The clinical picture of the disease consists of deterioration in the general condition, with widespread pain, confusion, skin eruptions, bilious vomiting, and so on. Under these conditions, if Job did exist, and if the retrospective medical history is reliable, the most likely diagnosis is that of scabies rather than leprosy.

Full Text Available Introduction: Henoch schonlein purpura (HSP is a self-limited systemic disease with multiorgan involvement. While cutaneous involvement may wary, presenting as itching papules is not a common manifestation. In this report we discuss a case of HSP which was presented solely with itching papules; mistaken for scabies. Case presentation: A 7 year old boy presented with itchy palpable papules without any gastrointestinal or urinary problem which was primary taught to be an ectoparasitic infestation. During the hospitalization the patient developed abdominal pain as well as hematuria and the diagnosis became more evident. The skin biopsy showed perivascular inflammatory cells infiltration in epidermis, perivascular fibrinoid necrosis and leukocytoclastic vasculitis. The patient received corticosteroids and discharged healthy.Conclusion: While HSP may have different cutaneous manifestation, presenting as only itchy papules may complicate the diagnosis and physicians should always keep in mind that HSP might be presented as other common infestations unresponsive to treatment.

Impetigo, scabies, and fungal skin infections disproportionately affect populations in resource-limited settings. Evidence for standard treatment of skin infections predominantly stem from hospital-based studies in high-income countries. The evidence for treatment in resource-limited settings is less clear, as studies in these populations may lack randomisation and control groups for cultural, ethical or economic reasons. Likewise, a synthesis of the evidence for public health control within endemic populations is also lacking. We propose a systematic review of the evidence for the prevention, treatment and public health management of skin infections in resource-limited settings, to inform the development of guidelines for the standardised and streamlined clinical and public health management of skin infections in endemic populations. The protocol has been designed in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols statement. All trial designs and analytical observational study designs will be eligible for inclusion. A systematic search of the peer-reviewed literature will include PubMed, Excertpa Medica and Global Health. Grey literature databases will also be systematically searched, and clinical trials registries scanned for future relevant studies. The primary outcome of interest will be the clinical cure or decrease in prevalence of impetigo, scabies, crusted scabies, tinea capitis, tinea corporis or tinea unguium. Two independent reviewers will perform eligibility assessment and data extraction using standardised electronic forms. Risk of bias assessment will be undertaken by two independent reviewers according to the Cochrane Risk of Bias tool. Data will be tabulated and narratively synthesised. We expect there will be insufficient data to conduct meta-analysis. The final body of evidence will be reported against the Grades of Recommendation, Assessment, Development and Evaluation grading system. The evidence

Impetigo is caused by both Streptococcus pyogenes and Staphylococcus aureus; the relative contributions of each have been reported to fluctuate with time and region. While S. aureus is reportedly on the increase in most industrialised settings, S. pyogenes is still thought to drive impetigo in endemic, tropical regions. However, few studies have utilised high quality microbiological culture methods to confirm this assumption. We report the prevalence and antimicrobial resistance of impetigo pathogens recovered in a randomised, controlled trial of impetigo treatment conducted in remote Indigenous communities of northern Australia. Each child had one or two sores, and the anterior nares, swabbed. All swabs were transported in skim milk tryptone glucose glycogen broth and frozen at -70°C, until plated on horse blood agar. S. aureus and S. pyogenes were confirmed with latex agglutination. From 508 children, we collected 872 swabs of sores and 504 swabs from the anterior nares prior to commencement of antibiotic therapy. S. pyogenes and S. aureus were identified together in 503/872 (58%) of sores; with an additional 207/872 (24%) sores having S. pyogenes and 81/872 (9%) S. aureus, in isolation. Skin sore swabs taken during episodes with a concurrent diagnosis of scabies were more likely to culture S. pyogenes (OR 2.2, 95% CI 1.1 - 4.4, p = 0.03). Eighteen percent of children had nasal carriage of skin pathogens. There was no association between the presence of S. aureus in the nose and skin. Methicillin-resistance was detected in 15% of children who cultured S. aureus from either a sore or their nose. There was no association found between the severity of impetigo and the detection of a skin pathogen. S. pyogenes remains the principal pathogen in tropical impetigo; the relatively high contribution of S. aureus as a co-pathogen has also been confirmed. Children with scabies were more likely to have S. pyogenes detected. While clearance of S. pyogenes is the key

Canine scabies is a challenging disease to diagnose because sarcoptic mites are hard to find on skin scrapings. The purpose of this study was to evaluate a serologic enzyme-linked immunosorbent assay (ELISA) as an aid in the diagnosis of canine scabies. In addition, serum samples were obtained post treatment to determine the duration and persistence of circulating scabies antibodies after resolution of natural infection. Nineteen dogs diagnosed with sarcoptic mange and 38 control dogs were tested. Sixteen scabies-infested dogs showed positive pretreatment ELISA results (84.2% sensitivity). Thirty-four control dogs showed negative ELISA results (89.5% specificity). In the 11 scabies dogs from which multiple post treatment serum samples were obtained, detectable antibodies were not present 1 month after treatment in four cases, but were present for 1-4.5 months post treatment in seven dogs. Our results suggest that this scabies ELISA test is useful in the diagnosis of canine scabies.

The infectious causes of cutaneous vasculitis are well known and include streptococcal infections among others. Cases resulting from parasitic infection are less frequent. Scabies, which is currently on the increase, has only been reported in a few isolated cases. Herein, we report two noteworthy cases of profuse scabies complicated by cutaneous vasculitis. Case 1: a 90-year-old woman, residing in a nursing home, was admitted to our dermatology department complaining of pruritus, present for one month, predominantly on the inside of the thighs and on the buttocks, associated with purpuric lesions on the lower limbs. A skin biopsy revealed leukocytoclastic vasculitis. A diagnosis of scabies was based on severe pruritus and hypereosinophilia and was confirmed by microscopic examination of the parasitology sample and the skin biopsy sample. Despite thorough investigation, no other cause of vasculitis could be found. Complete regression of the skin lesions was achieved with scabies treatment only, without any specific treatment for the vasculitis. Case 2: a 74-year-old man, living in a nursing home, was hospitalized for purpuric papules on the lower limbs, present for one month. Physical examination revealed linear patterns in the interdigital spaces associated with scabies evident on dermoscopic examination. The skin biopsy revealed signs of vasculitis. As in our first case, no aetiology of vasculitis was found and a favorable outcome was achieved by means of scabies treatment alone with no specific treatment for vasculitis. Both of our patients presented scabies and vasculitis. In view of the absence of other causes of vasculitis and of the complete regression of lesions due to vasculitis without recurrence achieved with the scabies treatment alone, a diagnosis was made of scabietic vasculitis, probably as a result of cutaneous hypersensitivity reaction to humeral mediators.

The pruritic skin disease scabies is caused by the burrowing of the itch mite Sarcoptes scabiei (De Geer). It is difficult to diagnose this disease because its symptoms often resemble those of other skin diseases. No reliable blood or molecular diagnostic test is available. The aim of this project was to begin to characterize the scabies proteome to identify scabies mite proteins, including those that may be useful in the development of a diagnostic test or vaccine. Various scabies mite extracts were separated by two-dimensional electrophoresis, and 844 Coomassie Blue-stained protein spots were excised, subjected to trypsin digestion, and analyzed by Matrix Assisted Laser Desorption/Ionization Time-Of-Flight/Time-Of-Flight (MALDI-TOF/TOF) mass spectrometry (MS). Tryptic fragment sequences determined by MS were searched against the recently completed S. scabiei annotated genome, leading to the identification of >150 proteins. Only 10 proteins hit to previously identified scabies proteins including actin, tropomyosin, and several ABC transporters. Thirteen proteins had homology to dust mite allergens (members of groups 8, 10, 13, 17, 20, 25, and 28). Most other sequences showed some homology to proteins in other mites and ticks including homologs of calmodulin, calreticulin, lipocalin, and glutathione-S-transferase. These data will now allow the identification of the proteins to which scabies patients produce antibodies, including those that may be good candidates for inclusion in a diagnostic test and vaccine.

The genes coding for 23 selected proteins were cloned into E. coli and the expressed recombinant proteins were screened with serum from patients with confirmed ordinary scabies.We identified 50 different proteins produced by S. scabiei, 34 of which were not previously identified, and determined that 66% were recognized by patient IgM and/or IgG. Fourteen proteins were screened for use in a diagnostic test but none possessed enough sensitivity and specificity to be useful. Six of the 9 proteins selected for the possibility that they may be immunomodulatory were not recognized by antibodies in patient serum.Thirty-three proteins that bound IgM and/or IgG from the serum of patients with ordinary scabies were identified. None of the 14 tested were useful for inclusion in a diagnostic test. The identities of 16 proteins that are not recognized as antigens by infected patients were also determined. These could be among the molecules that are responsible for this mite's ability to modulate its host's innate and adaptive immune responses.

The pathological findings in Japanese raccoon dogs with sarcoptic mange infection associated with death from sepsis are described. Microscopical lesions of the skin were consistent with those described previously in wildlife populations with Sarcoptes infection, but secondary lesions were also present in the lungs, heart, kidneys, liver, spleen and brain of these animals. This infection was therefore very similar to "crusted scabies" or "Norwegian scabies" in man and was characterized by severe pathology and high mortality, with deaths frequently occurring due to sepsis.

Sequential changes in pathology were examined for scabies-infested dogs to determine the effects of infestation with Sarcoptes scabiei var. canis. During 8 wk of infestation with S. scabiei, the progression of the disease was evaluated weekly by skin scrape, clinical examination, and blood analyses. At 8 wk, selected organs were microscopically examined for histopathology. All infested dogs developed an advanced level of scabies infestation by 8 wk. Of the 36 blood parameters evaluated, only values for erythrocyte sedimentation rate (ESR) deviated significantly from the normal ranges for dogs. However, infested dogs had significantly (P dogs. Red blood cell levels for infested dogs dropped significantly (P dogs compared to controls, some individual infested dogs exhibited eosinophilia at 4-8 wk of infestation. The ESRs for infested dogs were significantly (P dogs prior to infestation or control dogs. All parameters except neutrophils had returned to preinfestation levels by 2 wk after treatment for scabies. Neutrophil concentrations were no longer significantly different by 4 wk posttreatment. There were no significant differences in serum enzyme, biochemical and electrolyte concentrations between infested and control dogs.(ABSTRACT TRUNCATED AT 250 WORDS)

To investigate the epidemiology of pityriasis rosea in primary care settings in Hong Kong and to analyze for temporal clustering. Retrospective epidemiologic study. Six primary care teaching practices affiliated with a university. Patients Forty-one patients with pityriasis rosea, 564 patients with atopic dermatitis (negative control condition), and 35 patients with scabies (positive control condition). We retrieved all records of patients with pityriasis rosea, atopic dermatitis, or scabies diagnosed in 3 years. We analyzed temporal clustering by a method based on a regression model. The monthly incidence of pityriasis rosea is negatively but insignificantly correlated with mean air temperature (gamma s = -0.41, P =.19) and mean total rainfall (gamma s = -0.34, P =.27). Three statistically significant clusters with 7, 6, and 7 cases were identified (P =.03), occurring in the second coldest month in the year (February), the second hottest month (July), and a temperate month (April), respectively. For atopic dermatitis (negative control condition), the nonclustering regression model was selected by Akaike information criteria. For scabies (positive control condition), 1 cluster of 20 cases was detected (P =.03). Significant temporal clustering independent of seasonal variation occurred in our series of patients with pityriasis rosea. This may be indicative of an infectious cause.

Metabolic acidosis in an infant associated with permethrin toxicity.

Pyrethroids are broad-spectrum insecticides. Permethrin intoxication due to topical application has not been documented in humans. We report a 20-month-old infant who had used 5% permethrin lotion topically for scabies treatment. Approximately 60 mL (20 mL/day) was used and after the third application he developed agitation, nausea, vomiting, respiratory distress, tachycardia, and metabolic acidosis. His clinical symptoms and metabolic acidosis normalized within 20 hours. His follow-up was unremarkable. Toxicity of permethrin is rare, and although permethrin is a widely and safely used topical agent in the treatment of scabies and lice, inappropriate use may rarely cause toxicity. Moreover, in cases of unexplained metabolic acidosis, topically applied medications should be carefully investigated. © 2014 Wiley Periodicals, Inc.

This study was designed to assess the accuracy of a commercial enzyme-linked immunosorbent assay for the diagnosis of canine scabies. Serum samples from 37 dogs were examined blind; 12 had sarcoptic mange confirmed by the identification of mites in skin scrapings, 12 were atopic (with positive intradermal reactions to one or more aeroallergens, including Dermatophagoides farinae), and 13 were healthy dogs with no history of skin disease. Optical density values of more than 0.16 were considered positive, 0.145 to 0.16 were considered questionable and less than 0.145 were considered negative. Ten of the 12 dogs with scabies were positive, all 12 atopic dogs were negative, and 11 of the 13 healthy dogs were negative and two were questionable.

Paramyosin from the parasitic mite Sarcoptes scabiei: cDNA cloning and heterologous expression.

Mattsson, J G; Ljunggren, E L; Bergström, K

2001-05-01

The burrowing mite Sarcoptes scabiei is the causative agent of the highly contagious disease sarcoptic mange or scabies. So far, there is no in vitro propagation system for S. scabiei available, and mites used for various purposes must be isolated from infected hosts. Lack of parasite-derived material has limited the possibilities to study several aspects of scabies, including pathogenesis and immunity. It has also hampered the development of high performance serological assays. We have now constructed an S. scabiei cDNA expression library with mRNA purified from mites isolated from red foxes. Immunoscreening of the library enabled us to clone a full-length cDNA coding for a 102.5 kDa protein. Sequence similarity searches identified the protein as a paramyosin. Recombinant S. scabiei paramyosin expressed in Escherichia coli was recognized by sera from dogs and swine infected with S. scabiei. We also designed a small paramyosin construct of about 17 kDa that included the N-terminal part, an evolutionary variable part of the helical core, and the C-terminal part of the molecule. The miniaturized protein was efficiently expressed in E. coli and was recognized by sera from immunized rabbits. These data demonstrate that the cDNA library can assist in the isolation of important S. scabiei antigens and that recombinant proteins can be useful for the study of scabies.

Leprosy in the Bible.

Grzybowski, Andrzej; Nita, Małgorzata

2016-01-01

For many years, the biblical term tzaraat has referred to leprosy. In fact, the disease or diseases described under this name have no relationship to leprosy, as it was known in the Middle Ages or today; moreover, the term referred not only to skin disease, but also to the state of the ritual impurity and punishment for the sins. Although the real nature of tzaraat remains unknown, the differential diagnosis might include the following: Psoriasis, seborrheic dermatitis, favus, dermatophyte infections, nummular dermatitis, atopic dermatitis, pityriasis rosea, crusted scabies, syphilis, impetigo, sycosis barbae, alopecia areata, furuncles, scabies, neurodermatitis, scarlet fever, lupus erythematosus, lichen sclerosus et atrophicus, folliculitis decalvans, morphea, sarcoidosis, and lichen planopilaris. Leprosy became interchangeable with the biblical leprosy due to two inaccurate translations: The Hebrew tzaraat was first translated into Greek as leprosy in the sixth century, and later, the word leprosy was translated into Arabic as lepra in the ninth century.

2017-06-20

The disease scabies is one of the earliest diseases of humans for which the cause was known. It is caused by the mite, Sarcoptes scabiei, that burrows in the epidermis of the skin of humans and many other mammals. This mite was previously known as Acarus scabiei DeGeer, 1778 before the genus Sarcoptes was established (Latreille 1802) and it became S. scabiei. Research during the last 40 years has tremendously increased insight into the mite's biology, parasite-host interactions, and the mechanisms it uses to evade the host's defenses. This review highlights some of the major advancements of our knowledge of the mite's biology, genome, proteome, and immunomodulating abilities all of which provide a basis for control of the disease. Advances toward the development of a diagnostic blood test to detect a scabies infection and a vaccine to protect susceptible populations from becoming infected, or at least limiting the transmission of the disease, are also presented.

Genes for the expression of interleukin-1α (IL-1α precursor, IL-1β, granulocyte/macrophage-colony stimulating factor (GM-CSF precursor, and G-CSF precursor were up-regulated 2.8- to 7.4-fold, paralleling cytokine secretion profiles. A large number of genes involved in epithelium development and keratinization were also differentially expressed in response to live scabies mites. Thus, these skin cells are directly responding as expected in an inflammatory response to products of the mites and the disruption of the skin's protective barrier caused by burrowing. This suggests that in vivo the interplay among these skin cells and other cell types, including Langerhans cells, dendritic cells, lymphocytes and endothelial cells, is responsible for depressing the host's protective response allowing these mites to survive in the skin.

Response of Human Skin Equivalents to Sarcoptes scabiei

MORGAN, MARJORIE S.; ARLIAN, LARRY G.

2010-01-01

Studies have shown that molecules in an extract made from bodies of the ectoparasitic mite, Sarcoptes scabiei De Geer, modulate cytokine secretion from cultured human keratinocytes and fibroblasts. In vivo, in the parasitized skin, these cells interact with each other by contact and cytokine mediators and with the matrix in which they reside. Therefore, these cell types may function differently together than they do separately. In this study, we used a human skin equivalent (HSE) model to investigate the influence of cellular interactions between keratinocytes and fibroblasts when the cells were exposed to active/burrowing scabies mites, mite products, and mite extracts. The HSE consisted of an epidermis of stratified stratum corneum, living keratinocytes, and basal cells above a dermis of fibroblasts in a collagen matrix. HSEs were inoculated on the surface or in the culture medium, and their cytokine secretions on the skin surface and into the culture medium were determined by enzyme-linked immunosorbent assay. Active mites on the surface of the HSE induced secretion of cutaneous T cell-attracting chemokine, thymic stromal lymphopoietin, interleukin (IL)-1α, IL-1β, IL-1 receptor antagonist (IL-1ra), IL-6, IL-8, monocyte chemoattractant protein-1, granulocyte/macrophage colony-stimulating factor, and macrophage colony-stimulating factor. The main difference between HSEs and monocultured cells was that the HSEs produced the proinflammatory cytokines IL-1α and IL-1β and their competitive inhibitor IL-1ra, whereas very little of these mediators was previously found for cultured keratinocytes and fibroblasts. It is not clear how the balance between these cytokines influences the overall host response. However, IL-1ra may contribute to the depression of an early cutaneous inflammatory response to scabies in humans. These contrasting results illustrate that cell interactions are important in the host’s response to burrowing scabies mites. PMID:20939384

De novo Biosynthesis of "Non-Natural" Thaxtomin Phytotoxins.

Science.gov (United States)

Winn, Michael; Francis, Daniel; Micklefield, Jason

2018-03-30

Thaxtomins are diketopiperazine phytotoxins produced by Streptomyces scabies and other actinobacterial plant pathogens that inhibit cellulose biosynthesis in plants. Due to their potent bioactivity and novel mode of action there has been considerable interest in developing thaxtomins as herbicides for crop protection. To address the need for more stable derivatives, we have developed a new approach for structural diversification of thaxtomins. Genes encoding the thaxtomin NRPS from S. scabies, along with genes encoding a promiscuous tryptophan synthase (TrpS) from Salmonella typhimurium, were assembled in a heterologous host Streptomyces albus. Upon feeding indole derivatives to the engineered S. albus strain, tryptophan intermediates with alternative substituents are biosynthesized and incorporated by the NRPS to deliver a series of thaxtomins with different functionalities in place of the nitro group. The approach described herein, demonstrates how genes from different pathways and different bacterial origins can be combined in a heterologous host to create a de novo biosynthetic pathway to "non-natural" product target compounds. © 2018 Wiley-VCH Verlag GmbH & Co.

Interrelationships among bacteria, protozoa, helminths, and ectoparasites were explored in a cross-sectional survey of 213 pregnant and 99 lactating indigenous women. Prevalences in pregnancy and lactation, respectively, were: vaginitis (89.2%; 46.8%), vaginal trichomoniasis (75.3%; 91.1%), bacterial vaginosis (BV; 60.6%; 63.3%), hookworm (56.6%; 47.8%), asymptomatic bacteriuria/urinary tract infection (AB/UTI; 56.2%; 36.2%), cervicitis (33.3%; 6.3%), vaginal yeast (24.9%; 11.4%), Ascaris (32.5%; 17.4%), vaginal diplococci (20.4%; 31.6%), caries (19.7%; 18.2%), scabies (17.4%; 8.1%), and Trichuris (12.5%; 8.7%). Multiple regressions revealed positive associations during pregnancy (trichomoniasis and AB/UTI; diplococci and Ascaris) and lactation (yeast and scabies). Negative associations were detected in pregnancy (BV and trichomoniasis; hookworm and diplococci) and lactation (BV and yeast). Vaginal Lactobacillus reduced odds of diplococci in pregnancy and lactation, but increased Ascaris eggs per gram (epg) and odds of trichomoniasis in pregnancy and yeast in lactation. These associations raised a concern that treatment of one condition may increase the risk of another. © The American Society of Tropical Medicine and Hygiene.

To establish priorities for zoonoses surveillance, prevention, and control in Bogotá, Colombia. A Delphi panel of experts in veterinary and human medicine was conducted using a validated prioritization method to assess the importance of 32 selected zoonoses. This exercise was complemented by a questionnaire survey, using the knowledge, attitudes, and practices (KAP) methodology, administered in 19 districts of Bogotá from September 2009 to April 2010 to an at-risk population (workers at veterinary clinics; pet shops; butcher shops; and traditional food markets that sell poultry, meat, cheese, and eggs). A risk indicator based on level of knowledge about zoonoses was constructed using categorical principal component and logistic regression analyses. Twelve experts participated in the Delphi panel. The diseases scored as highest priority were: influenza A(H1N1), salmonellosis, Escherichia coli infection, leptospirosis, and rabies. The diseases scored as lowest priority were: ancylostomiasis, scabies, ringworm, and trichinellosis. A total of 535 questionnaires were collected and analyzed. Respondents claimed to have had scabies (21%), fungi (8%), brucellosis (8%), and pulicosis (8%). Workers with the most limited knowledge on zoonoses and therefore the highest health risk were those who 1) did not have a professional education, 2) had limited or no zoonoses prevention training, and 3) worked in Usme, Bosa, or Ciudad Bolívar districts. According to the experts, influenza A(H1N1) was the most important zoonoses. Rabies, leptospirosis, brucellosis, and toxoplasmosis were identified as priority diseases by both the experts and the exposed workers. This is the first prioritization exercise focused on zoonoses surveillance, prevention, and control in Colombia. These results could be used to guide decision-making for resource allocation in public health.

Full Text Available BACKGROUND The incidence and the spectrum of paediatric dermatological diseases vary from one part of the world to another.1 Skin diseases, though very common in many developing countries are not often regarded as a significant health problem.2 Majority of the skin diseases tend to occur in children under the age of 5 years. This high prevalence could be due to the lower immunity or higher frequency of hospital visits by infants due to greater parental care. The aim of the study is to compare the present spectrum of cutaneous disorders between two age groups of children less than 5 years and 5-14 years old and their correlation with socioeconomic status attending primary health centre, Bangalore rural, south. MATERIALS AND METHODS A prospective cross-sectional study was conducted from March 22 to November 22, 2017, in children with skin disorders under 14 years old who attended primary health centre at Bangarappanagar and Uttarahalli in Bangalore. RESULTS A total of 522 children with skin diseases, 486 children were included in the study and they were divided into two groups of those less than 5 years with the sex ratio (M:F 1.5:1 and 5-14 years old with the sex ratio (M:F 1.3:1. The most common dermatological disease among less than 5 years age group was infections, eczema, infestations and pigmentary disorders and the most common dermatological diseases between 5-14 years was infections, scabies, eczema and acne. CONCLUSION Skin problems mainly scabies, tinea, impetigo and eczema were common in children who attended the primary health centres at Bangalore rural. There is a high prevalence of communicable diseases among children belonging to parents of low socioeconomic status. Community health education regarding personal hygiene coupled with that of the surrounding environment can help in controlling these diseases in the long run.

Background: The morbidity associated with skin diseases makes them an important public health problem. Very scanty literature is found on the problem which is either disease-based, community based or a specified population group-based. objective of this study was to assess the pattern of skin diseases in patients and to determine their relation with demographic characteristics. Methods: This descriptive study was conducted at dermatology out-patient department of liaquat university hospital, jamshoro, pakistan for the period from 10th january to 10th february 2008. Four hundred and eleven patients were enrolled during the study period. The study population comprised of newly diagnosed cases as well as relapsing cases presenting at the facility. The criterion for registering the patients was clinical diagnosis although few cases were supported by investigations, too. The data was collected through a pre-designed questionnaire and analysed through spss-12. Result: Skin problems are fairly common among children and women. in children of less than 10 years age, 82.5% visiting the facility suffer from infectious skin diseases. among the infectious diseases, scabies is highly prevalent disease (45.5%). the majority of the patients belong to rural or slum areas (77.2%), low socio-economic strata (68.9%), and living in overcrowded families (82%). a strong association between skin infections and water inadequacy (p=0.016) was found, and scabies shows a strong statistical association with overcrowding (p=0.025). Conclusion: The skin diseases involve every age strata of our population but it is fairly common in younger age group, women, and people who do not practice hygiene. Out-reach services for the rural and slum communities and health education will give good results on prevention of skin diseases. (author)

Sarcoptic mange (or scabies) is an important skin disease which can affect a variety of species including humans, cattle, goats, sheep, horses, pigs, rabbits, and dogs. Approximately 300 million people are affected worldwide and in lifestock animals the infestation may lead to substantial economic losses caused by depression in growth and feed conversion rates. Diagnosis of Sarcoptes infestation is difficult and only a few serological tests have been developed using whole mite antigen for diagnosis of mange in animals. Here we describe the isolation and characterisation of cDNAs of several immunoreactive clones and their recombinant expression in Escherichia coli. Three of the proteins contain repetitive sequences which suggests that they might be involved in immune evasion. The application of these antigens in serodiagnosis and the suitability for diagnosis is discussed.

How 'dangerous’ are migrants’ bodies? Narratives about disease and public health and techniques of governance

Full Text Available In this text I represent the narratives about migrants which are related to their bodies as potential/plausible carriers of diseases that could be spread to local population. The narratives are considered as special manifestations of the discourse of fear, though which migrants are being construed as a form of corporeal security threat. In particular, through the analysis of narratives about ebola and scabies, the potential to use the fear from disease as symbol and instrument of political power is indicated, when a disease ceases to be medical problem and becomes predominantly a social one. Fear from disease and measures undertaken to annul it are thus integrated into techniques of governance.

Of several hundred microorganisms randomly selected from the environment, only a fungal isolate identified as Aspergillus niger van Tiegham var. niger was found to transform the phytotoxin thaxtomin A to much less toxic metabolites. The rate and extent of transformation of thaxtomin A was tested under a variety of conditions, including different growth media, biomass concentrations, incubation periods, and shaker speeds. Under optimum conditions the fungus converted thaxtomin A into two major and five minor metabolites. The two major metabolites and three of the five minor metabolites were fully characterized by a combination of mass spectral and nuclear magnetic resonance techniques. When assayed on aseptically produced mini-tubers, the major metabolites proved to be much less phytotoxic than thaxtomin A. (author)

Early detection of several skin-related neglected tropical diseases (skin NTDs)-including leprosy, Buruli ulcer, yaws, and scabies- may be achieved through school surveys, but such an approach has seldom been tested systematically on a large scale in endemic countries. Additionally, a better understanding of the spectrum of skin diseases and the at-risk populations to be encountered during such surveys is necessary to facilitate the process. We performed a school skin survey for selected NTDs and the spectrum of skin diseases, among primary schoolchildren aged 5 to 15 in Côte d'Ivoire, West Africa. This 2-phase survey took place in 49 schools from 16 villages in the Adzopé health district from November 2015 to January 2016. The first phase involved a rapid visual examination of the skin by local community healthcare workers (village nurses) to identify any skin abnormality. In a second phase, a specialized medical team including dermatologists performed a total skin examination of all screened students with any skin lesion and provided treatment where necessary. Of a total of 13,019 children, 3,504 screened positive for skin lesions and were listed for the next stage examination. The medical team examined 1,138 of these children. The overall prevalence of skin diseases was 25.6% (95% CI: 24.3-26.9%). The predominant diagnoses were fungal infections (n = 858, prevalence: 22.3%), followed by inflammatory skin diseases (n = 265, prevalence: 6.9%). Skin diseases were more common in boys and in children living along the main road with heavy traffic. One case of multi-bacillary type leprosy was detected early, along with 36 cases of scabies. Our survey was met with very good community acceptance. We carried out the first large-scale integrated, two-phase pediatric multi-skin NTD survey in rural Côte d'Ivoire, effectively reaching a large population. We found a high prevalence of skin diseases in children, but only limited number of skin NTDs. With the lessons learned

Scabies caused by the genus Sarcoptes scabiei var canis is a prevalent infection in dogs and affects abandoned, malnourished and overcrowded animals, causing hair loss and an intensely pruritic crusting dermatitis. In humans the manifestation is a self-limiting pruritic dermatitis, but persistent cases are described. An outbreak of sarcoptic mange is reported in a family group (seven people, including a 5 month infant and his mother). The infective source was their own house dog who was taken from the street. The diagnosis was confirmed by the detection of mites and eggs in the acarotest of the dog and mites of S. scabei in the infant. Sarcoptic mange should be suspected in individuals with allergic dermatitis who have contact with dogs. Treatment in humans is usually symptomatic and may need miticides if the infection persists. The control of the disease requires an appropriate pet treatment.

Full Text Available This study compares the efficacy of skin impression with acetate tape and the deep skin scraping test to find D. canis and S. scabiei in dogs. During six months, 134 samples were collected by both techniques from 115 dogs treated at the dermatology service of the Veterinary Hospital of the Federal University of Santa Maria (HVU-UFSM. Of these patients, 27 had demodicosis and 12 had scabies. The impression with acetate tape test (ITT was shown to be significantly superior to the deep skin scraping test (DSST in finding D. canis and S. scabiei mites (p = 0.007. Based on our results we could conclude that acetate tape impression is a reliable method for diagnosing and monitoring therapy of dermatopathies caused by mites and can be used to replace the traditional deep skin scraping method. In addition, since it is less traumatic for the dog, this method shows more acceptance by the owner.

There are few licensed options for the treatment of canine sarcoptic mange. To evaluate the efficacy of fluralaner in dogs with sarcoptic mange infestation. Seventeen dogs with a diagnosis of Sarcoptes scabiei based on positive skin scrapings. A single dose of oral fluralaner was administered according to the manufacturer's instructions. Assessments of pruritus and lesions were performed every 7 days for 1 month. By Day 14 post-treatment, skin scrapings from all dogs were negative for mites. At the beginning of the study there was a negative correlation between body weight of the subject and pruritus [Pearson correlation coefficient (PCC) = -0.396, P = 0.007] and a positive correlation between pruritus and lesion severity (PCC 0.755, P = 0.0001). Significant decreases in lesion size and pruritus were observed within the first 14-21 days, respectively, and improvement in these parameters continued until the end of the study at Day 28. Fluralaner was effective in eliminating scabies mites within 14 days and significantly resolved the clinical signs associated with sarcoptic mange within 21 days after a single dose. © 2016 ESVD and ACVD.

Norwegian or Crusted Sarcoptic Mange in Two Leishmanial Dogs.

Science.gov (United States)

Kaltsogianni, Flora; Farmaki, Rania; Koutinas, Alexander F

Norwegian or crusted scabies (N/CS) is a rare skin disease with very few cases reported in the dog or the cat. Two adult, stray dogs were admitted in our clinic with a generalized, multifocal to diffuse and nonpruritic dermatitis that was characterized by severe crusting, scaling, and ulceration. In both instances, leishmaniosis and N/CS were diagnosed by immunofluorescent antibody test serology, lymph node cytology, and skin scrapings in which high numbers of Sarcoptes mites were found. The combination of miticidal and antileishmanial treatment, supported by topical treatment and nutritional support, resulted in the complete resolution of the skin lesions and spectacular improvement of the body condition in both cases. Dog 1 eventually died from end-stage kidney disease attributed to leishmaniosis-associated glomerulonephritis, whereas the also proteinuric dog 2 remains clinically healthy. The manifestation of the rare type of N/CS in these dogs could be attributed to cell-mediated immunosuppression, which was most likely induced by leishmaniosis and malnutrition. The necessity of searching for leishmaniosis in those scabietic cases, especially in the endemic areas of leishmaniosis, is strongly recommended.

Genome Content and Phylogenomics Reveal both Ancestral and Lateral Evolutionary Pathways in Plant-Pathogenic Streptomyces Species

Streptomyces spp. are highly differentiated actinomycetes with large, linear chromosomes that encode an arsenal of biologically active molecules and catabolic enzymes. Members of this genus are well equipped for life in nutrient-limited environments and are common soil saprophytes. Out of the hundreds of species in the genus Streptomyces, a small group has evolved the ability to infect plants. The recent availability of Streptomyces genome sequences, including four genomes of pathogenic species, provided an opportunity to characterize the gene content specific to these pathogens and to study phylogenetic relationships among them. Genome sequencing, comparative genomics, and phylogenetic analysis enabled us to discriminate pathogenic from saprophytic Streptomyces strains; moreover, we calculated that the pathogen-specific genome contains 4,662 orthologs. Phylogenetic reconstruction suggested that Streptomyces scabies and S. ipomoeae share an ancestor but that their biosynthetic clusters encoding the required virulence factor thaxtomin have diverged. In contrast, S. turgidiscabies and S. acidiscabies, two relatively unrelated pathogens, possess highly similar thaxtomin biosynthesis clusters, which suggests that the acquisition of these genes was through lateral gene transfer.

Full Text Available BACKGROUND AND AIMS: Human immunodeficiency virus (HIV is associated with various mucocutaneous features, which may be the first pointer towards the existence of HIV infection. This study was done to note the different mucocutaneous lesions present in the HIV population in eastern India. METHODS: Four hundred and ten HIV seropositive patients attending the outpatient and inpatient departments were included in the study. RESULTS: Out of 410 HIV positives, 40% had mucocutaneous involvement at presentation. The mean age of the study population was 29 years and male to female ratio was 2.5:1. The common mucocutaneous morbidities included oral candidiasis (36%, dermatophytosis and gingivitis (13% each, herpes zoster (6%, herpes simplex and scabies (5% each. A striking feature, noted in 36% males, was straightening of hairs. Genital herpes was the commonest genital ulcer disease. Lesions associated with declining immunity included oral candidiasis, oral hairy leukoplakia and herpes zoster with median CD4 counts of 98, 62 and 198/ L respectively. CONCLUSION: Early recognition of mucocutaneous manifestations and associated STDs help in better management of HIV/AIDS.

[Knowledge of zoonoses transmission routes and of the species concerned among rural workers].

The aim of this study was to evaluate the level of awareness of zoonoses among rural workers and their potential associations with socio-demographic factors. A cross-sectional study was performed by holding personal interviews (N=110, n=94) using a structured questionnaire. The statistical analysis included the χ(2) test, the Student's t test and Pearson and Spearman correlations. The highest level of awareness was found for trichinosis, rabies and scabies. Species transmitting brucellosis, tuberculosis and anthrax were well known, but not their modes of transmission. The least known diseases were toxocariasis and hydatidosis, followed by leptospirosis and toxoplasmosis. Significant associations were found (p<0.001) between the knowledge of transmitting species and the modes of transmission. Senior male owners, married, and living in urban areas showed the highest overall knowledge of zoonoses. Awareness of zoonoses among rural workers is inadequate. Veterinarians in conjunction with risk insurers may play a key role in providing information to people at risk. Copyright © 2014 Asociación Argentina de Microbiología. Publicado por Elsevier España.

Background Debilitating skin infestations caused by the mite, Sarcoptes scabiei, have a profound impact on human and animal health globally. In Australia, this impact is evident across different segments of Australian society, with a growing recognition that it can contribute to rapid declines of native Australian marsupials. Cross-host transmission has been suggested to play a significant role in the epidemiology and origin of mite infestations in different species but a chronic lack of gene...

The efficacy of moxidectin 1% injectable for cattle was evaluated in dogs and rabbits with naturally acquired sarcoptic, demodectic or psoroptic mites. Twenty-two dogs with generalised demodicosis were orally treated with 0.4mg/kg moxidectin daily. Forty-one dogs suffering from sarcoptic mange were treated with 0.2-0.25mg/kg moxidectin either orally or subcutaneously every week for three to six times. Seven rabbits were treated orally with 0.2mg/kg moxidectin twice 10 days apart. Of the 22 dogs with demodicosis, 14% were stopped treatment because of side effects, 14% were lost and of the remaining 72% all were cured (mean therapy duration 2.4 months). Thirty-seven of the sarcoptic mange-infected dogs finished treatment and were cured. In 17% of dogs, side effects were noted. All seven rabbits treated for psoroptic mange were cured and did not show any side effect. Our results indicate that moxidectin is effective and a good alternative for the treatment of demodicosis and scabies in dogs and psoroptic mange in rabbits. Side effects seem to occur more frequently if applied subcutaneously, therefore the oral route should be preferred.

Mandrills are naturally infected with simian T-cell leukaemia virus type 1 (STLV-1) and simian immunodeficiency virus (SIV)mnd. In humans, dual infection with human immunodeficiency virus (HIV) and human T-cell lymphotropic virus type 1 (HTLV-1) may worsen their clinical outcome. We evaluated the effect of co-infection in mandrills on viral burden, changes in T-cell subsets and clinical outcome. The SIV viral load was higher in SIV-infected mandrills than in co-infected animals, whereas the STLV-1 proviral load was higher in co-infected than in mono-infected groups. Dually infected mandrills had a statistically significantly lower CD4+ T-cell count, a lower proportion of naive CD8+ T cells and a higher proportion of central memory cells. CD4(+) and CD8(+) T cells from SIV-infected animals had a lower percentage of Ki67 than those from the other groups. Co-infected monkeys had higher percentages of activated CD4(+) and CD8(+) T cells. Two co-infected mandrills with high immune activation and clonal integration of STLV provirus showed pathological manifestations (infective dermatitis and generalised scabies) rarely encountered in nonhuman primates.

The victories near Ulm and Elchingen, where the Napoleonic army took 60000 prisoners between 15th and 20th of October 1805, lead to the arrival at Troyes (county "Aube") of nearly 2000 Austrian soldiers to be held inside former monasteries among whose, mainly the Jacobinians casern where more than half of them stayed. At the beginning of 1806, the government sent the epidemics medical practitioner Dr Desgenettes on an inspection tour to control the state of health of the populations of places where foreign prisoners were held, which lead him through several counties of the North-eastern part of France, where he surveyed several diseases ranging from all kinds offevers up to dysentery, scabies or gangrenes. With the means of acid fumigations invented by the chemist Guyton Morveau from Dijon, the authorities took care of combating and preventing the epidemics in the caserns. As soon as October 1805, the epidemics medical practitioner Dr Pigeotte from Troyes wrote to the county governor his observations recommending a better diet, airing of the rooms and also calls to take some exercise. All these precepts showed an astonishing modernity.

The novel GrCEP12 peptide from the plant-parasitic nematode Globodera rostochiensis suppresses flg22-mediated PTI.

Chen, Shiyan; Chronis, Demosthenis; Wang, Xiaohong

The potato cyst nematode Globodera rostochiensis is a biotrophic pathogen that secretes effector proteins into host root cells to promote successful plant parasitism. In addition to the role in generating within root tissue the feeding cells essential for nematode development, (1) nematode secreted effectors are becoming recognized as suppressors of plant immunity. (2)(-) (4) Recently we reported that the effector ubiquitin carboxyl extension protein (GrUBCEP12) from G. rostochiensis is processed into free ubiquitin and a 12-amino acid GrCEP12 peptide in planta. Transgenic potato lines overexpressing the derived GrCEP12 peptide showed increased susceptibility to G. rostochiensis and to an unrelated bacterial pathogen Streptomyces scabies, suggesting that GrCEP12 has a role in suppressing host basal defense or possibly pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) during the parasitic interaction. (3) To determine if GrCEP12 functions as a PTI suppressor we evaluated whether GrCEP12 suppresses flg22-induced PTI responses in Nicotiana benthamiana. Interestingly, we found that transient expression of GrCEP12 in N. benthamiana leaves suppressed reactive oxygen species (ROS) production and the induction of two PTI marker genes triggered by the bacterial PAMP flg22, providing direct evidence that GrCEP12 indeed has an activity in PTI suppression.

1984-08-01

Sarcoptes scabiei var. canis served as a suitable model for the study of S. scabiei var. hominis survival. S. scabiei var. canis and var. hominis mites were found to survive off the host for 24 to 36 hours at room conditions (21 degrees C and 40% to 80% relative humidity [RH]), and the canine variety survived 19 days at 10 degrees C and 97% RH. Female mites survived decidedly longer than male mites at comparable conditions. Generally, higher RH values and lower temperatures favored survival, whereas higher temperature and lower RH led to early death. Most canine scabies mites that were held off the host for 36 hours at 75% RH and 22 degrees to 24 degrees C remained infective and penetrated when returned to the host. Live mites of the human variety that were recovered from bed linen slept on by infested patients would also penetrate a host after being held off a host for 96 hours in alternating 12-hour periods of room conditions and refrigeration. Penetration required less than 30 minutes for all life stages of both varieties, and it was accomplished by a mite secretion that dissolved the host tissue. Dislodged mites, particularly those in close proximity to the source, can be a likely source of infestation.

Anti-dermatophyte activity in vitro was evaluated using the agar dilution assay, and the therapeutic efficacy of B. hartwegii and Z. caribaeum were tested against experimental tinea pedis. The infected animals were treated intragastrically daily for seven days with 2.5 and 5 mg/kg of acetone extracts. The acetone extract of H. patens exhibited 100% growth inhibition against T. mentagrophytes and E. floccosum at 100.0 and 50.0 µg/ml, respectively, and B. hartwegii inhibited growth of M. canis and T. mentagrophytes at 100.0 µg/ml. Effective treatments with 2.5 mg/kg of Z. caribaeum and B. hartwegii extract were comparable with 1 mg/kg of clotrimazole in mice. Liver profile tests and histological analyses did not exhibit any signs of toxicity and the Ames test indicated that both extracts were safe when evaluated in strains TA98, TA100 and TA102. Our results suggest the potential for the future development of new antifungal drugs from B. hartwegii or Z. caribaeum.

Full Text Available Background: There are millions of working children worldwide. Several causes are suggested for this social evil of which poverty plays a significant role in whether a child will work. Objective: To determine the morbidity profile in the working children of gem polishing units of Jaipur, India and assess some of its associated socio-economic factors. Methods: The present cross-sectional study included 586 gem polishing working children. Using interview, the demographic characteristics, occupational and clinical history of participants were recorded. The reason for taking up the job, income from the job and their desire to attend the school were also asked to assess the social causes of child labor in this region. Results: The mean±SD age of the working children was 11.3±5.3 years. In most of the instances, parents compelled the child to take up the job. Supposed to increase the family income substantially, the child labor activity failed to do so. On the other hand, the children suffered from several occupational health problems like eyestrain, headache, gastrointestinal complaints (eg, abdominal pain, nausea, vomiting, and diarrhea, musculoskeletal symptoms (eg, back pain, pain in limbs, neck pain, and joint pains and skin diseases (eg, scabies, dermatitis. Conclusion: It seems that the social factors forcing the children to work in the studied region, result in deterioration of their health and affect their growth.

The Global Epidemiology of Impetigo: A Systematic Review of the Population Prevalence of Impetigo and Pyoderma.

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

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

Ghana is currently developing its provision of dermatology services. Epidemiologic studies of the skin diseases seen by Ghanaian dermatologists are needed to guide these efforts. We aimed to describe the skin conditions seen by and management practices of Ghanaian dermatologists in a specialized clinic. We conducted a chart review of new patients presenting to the Korle Bu Teaching Hospital dermatology clinic during 2014. Among the 529 patients studied, 700 discrete diagnoses were made. The most commonly diagnosed skin conditions were infections (24.6%) and dermatitis (24.6%); atopic dermatitis (8.4%), acne vulgaris (5.3%) and scabies (5.1%) were the most common specific diagnoses. Among infants, children, and adolescents, the most common diagnosis was atopic dermatitis (31.7%, 30.0%, and 14.9%, respectively). Acne vulgaris (12.0%) was the most common skin condition diagnosed in young adults. Irritant contact dermatitis (6.9%) was most common among adults. Lichen planus (9.9%) was the most commonly diagnosed skin condition in the senior population. Diagnoses made by dermatologists differed from the referral diagnosis documented by primary care providers for 65.8% of patients. The most frequently recommended treatments were antihistamines (47.8%) and topical steroids (38.4%). Only 18 diagnostic biopsies were performed. Our study summarizes the skin diseases seen and management practices of Ghanaian dermatologists in a specialized clinic at a large public teaching hospital. The results of this study can help to guide future dermatology education and development efforts in Ghana.

Physicians and veterinarians have many opportunities to partner in promoting the well-being of people and their pets, especially by addressing zoonotic diseases that may be transmitted between a pet and a human family member. Common cutaneous pet-acquired zoonoses are dermatophytosis (ringworm) and sarcoptic mange (scabies), which are both readily treated. Toxoplasmosis can be acquired from exposure to cat feces, but appropriate hygienic measures can minimize the risk to pregnant women. Persons who work with animals are at increased risk of acquiring bartonellosis (e.g., cat-scratch disease); control of cat fleas is essential to minimize the risk of these infections. People and their pets share a range of tick-borne diseases, and exposure risk can be minimized with use of tick repellent, prompt tick removal, and appropriate tick control measures for pets. Pets such as reptiles, amphibians, and backyard poultry pose a risk of transmitting Salmonella species and are becoming more popular. Personal hygiene after interacting with these pets is crucial to prevent Salmonella infections. Leptospirosis is more often acquired from wildlife than infected dogs, but at-risk dogs can be protected with vaccination. The clinical history in the primary care office should routinely include questions about pets and occupational or other exposure to pet animals. Control and prevention of zoonoses are best achieved by enhancing communication between physicians and veterinarians to ensure patients know the risks of and how to prevent zoonoses in themselves, their pets, and other people.

The objective of the present study was to investigate the curative and antioxidative efficacy of ivermectin and ivermectin + vitamin E-selenium, and the influence of these agents on oxidative stress parameters in canines infested by Sarcoptes scabiei. Twenty two sarcoptic mites infested dogs and nine healthy dogs of 6 months to 2 years of age were divided into three groups. Group I comprised of healthy dogs (n=9) whereas animals in group II (n=11) and III (n=11) were positive for scabies. Group II animals were treated with only 1% ivermectin @ 0.2 mg/kg SC whereas group III were additionally treated with Vitamin E and selenium (tocopherol 50 mg + Se 1.5 mg/ml) @ 0.5 ml/20 kg IM at weekly intervals for three times. Blood samples were collected on day 0 and 28 post therapy. The values for hemato-biochemical parameters and activities of antioxidant enzymes were significantly decreased (Pdogs in comparison to the healthy dogs on day 0 which approached normalcy by day 28 post therapy. The dogs of group III showed better clinical recovery in comparison to group II at the end of therapy. Thus, administration of vitamin E and selenium in addition to standard therapy can alleviate these alterations hastening the clinical recovery of diseased dogs and can be recommended as an adjunct therapy with miticides for canine sarcoptic mange. © Springer Science+Business Media B.V. 2011

Full Text Available Sheep's Sarcoptic Mange in North-eastern Algeria: Prevalence, Lesion and Clinical Aspects. Sarcoptic mange is the most common form of ovine mange in North-Eastern Algeria. It is caused by Sarcoptes scabiei var. ovis. An investigation was carried out to determine the prevalence and the seasonal profile of of the disease in sheep. During a period of one year, various aspects of sheep scabies were studied in different localities parts of North-Eastern Algeria. The average rate of infestation was 12.02% as judged by visiting livestock markets in Souk-Ahras, Guelma and Tebessa. The prevalence of the disease is high from December to March and low or zero during the remaining of the year. Sixty percent of flocks of the region of El-Tarf were found infested and 49.5% of animals were positive. The disease affected animals at any age. It occurred in ewes lambs and rams with prevalence of 50.5%, 37% and 22.3% respectively. The study of lesion and clinical aspects of affected sheep in El-Tarf revealed that 55% of individuals had lesions on the muzzle, 30% showed an extension of crust up to the chamfer, the basis of the ears and the lip,10% had their head completely covered by scabs; only 5% showed extension of the lesions to the legs. It seems that the parasitic burden is in strong correlation with the extent of the lesions.

Egypt has been plagued by many neglected tropical diseases since Pharaonic time. These diseases are Schistosomiasis, soil-transmitted helminthiasis, lymphatic filariasis, leishmaniasis and fascioliasis beside the epidermal parasitic skin diseases. Indeed, theses diseases still persist as public health problem in the country by the influence of demographic, socioeconomic and environmental obstacles. This study seeks for understanding the contribution of each factor in each obstacle in neglected tropical diseases perpetuation which in turn could help the governorate in planning integrated control strategies. It was found that poverty, unregulated urbanization and inadequate sanitation are important socioeconomic factors that have great effect on the transmission dynamics of the diseases. The environmental factors which affect the epidemiology of these diseases in the country are scarcity of water, construction of dams, land reclamation for agriculture beside the climate factors. Unfortunately, the panic increase in the population growth rate minimizes the efforts done by the governorate to elevate the public health services. These conditions also affect the transmission of epidermal parasitic skin diseases including scabies, head lice and hookworm-related cutaneous larva migrans. The control programs and the recommendations to combat the diseases were discussed. The present study showed that the ecological factors affecting each neglected tropical disease in Egypt are somewhat similar which makes it worthy to develop an integrated control approaches aiming at improving the leading factors of neglected tropical diseases circulation in the country.

To compare the diagnostic ability of pharmacists, nurses and general practitioners (GPs) for a range of skin conditions. An online study comprising 10 specifically developed dermatological case studies containing a digital image of the skin condition and a short case history. A total of 60 participants (20 representing each of pharmacists, GPs and primary care nurses) were required to identify the skin condition as well as the features in the case history that supported the diagnosis and the recommended first-line management approach for the condition. The mean diagnostic scores for each group were GPs = 8.8 (95% confidence interval, CI, 7.9-9.6), pharmacists = 6.2 (95% CI, 5.4-6.9) and nurses = 7.0 (95% CI, 6.1-7.9). Post hoc analysis revealed that the difference in mean diagnostic scores was significant (P skin conditions such as tinea corporis, scabies and plantar warts and overall at least 40% of pharmacists correctly identified all conditions. This small study has demonstrated that for all of the skin conditions considered, pharmacists' overall diagnostic scores were significantly different from those of GPs but similar to those of nurses for the conditions assessed. However, further work with a larger sample is required to determine the accuracy of these preliminary findings and to establish whether advice given by pharmacists in practice results in the appropriate course of action being taken. © 2013 Royal Pharmaceutical Society.

Ectoparasites of medical and veterinary importance: drug resistance and the need for alternative control methods.

McNair, Carol M

2015-03-01

Despite multiple attempts at eradication, many ectoparasites of humans and domestic livestock remain a persistent problem in the modern world. For many years, a range of pesticide drugs including organophosphates, organochlorides and synthetic pyrethroids provided effective control of these parasites; but intensive use of these drugs has led to the evolution of resistance in many target species. This paper aims to review the effectiveness of current control methods and discuss potential alternatives for the long term sustainable control of ectoparasites. Important medical ectoparasites such as scabies mites, head lice and bed bugs present a significant public health problem, and so adequate control methods are essential. Ectoparasites of domestic livestock and farmed fish (for example sheep scab mites, poultry mites and sea lice) are also of concern given the increasing strain on the world's food supply. These parasites have become resistant to several classes of pesticide, making control very difficult. Recently, an increasing amount of research has focussed on alternative control methods such as insect growth regulators, biological control using essential oils or fungi, as well as vaccine development against some ectoparasites of medical and veterinary importance. Drug resistance is prevalent in all of the ectoparasites discussed in this review. A wide variety of alternative control methods have been identified, however further research is necessary in order for these to be used to successfully control ectoparasitic diseases in the future. © 2015 Royal Pharmaceutical Society.

The mite Sarcoptes scabiei causes sarcoptic mange, or scabies, a disease that affects both animals and humans worldwide. Our interest in S. scabiei led us to further characterise a glutathione S-transferase. This multifunctional enzyme is a target for vaccine and drug development in several parasitic diseases. The S. scabiei glutathione S-transferase open reading frame reported here is 684 nucleotides long and yields a protein with a predicted molecular mass of 26 kDa. Through phylogenetic analysis the enzyme was classified as a delta-class glutathione S-transferase, and our paper is the first to report that delta-class glutathione S-transferases occur in organisms other than insects. The recombinant S. scabiei glutathione S-transferase was expressed in Escherichia coli via three different constructs and purified for biochemical analysis. The S. scabiei glutathione S-transferase was active towards the substrate 1-chloro-2,4-dinitrobenzene, though the positioning of fusion partners influenced the kinetic activity of the enzyme. Polyclonal antibodies raised against S. scabiei glutathione S-transferase specifically localised the enzyme to the integument of the epidermis and cavities surrounding internal organs in adult parasites. However, some minor staining of parasite intestines was observed. No staining was seen in host tissues, nor could we detect any antibody response against S. scabiei glutathione S-transferase in sera from naturally S. scabiei infected dogs or pigs. Additionally, the polyclonal sera raised against recombinant S. scabiei glutathione S-transferase readily detected a protein from mites, corresponding to the predicted size of native glutathione S-transferase.

Free-ranging raccoon dogs (Nyctereutes procyonoides) from Nogeyama Zoological Gardens, Kanazawa Zoological Gardens, and Yokohama Zoological Gardens frequently rescued dogs having Sarcoptes scabiei infestation. However, the epidemiology of S. scabiei infestation has not yet been elucidated. In the present study, we investigated the epidemiology of S. scabiei infestation in raccoon dogs and its influence on the population of masked palm civets in Yokohama, Japan. We examined records of raccoon dog rescue between 1981 and 2010 and classified the dogs into the following 4 categories on the basis of the reason for rescue: dogs with S. scabiei infestation, scabies-infested dogs involved in car accidents, uninfested dogs involved in car accidents, and other reasons for rescue. We found that the number of dogs rescued due to car accidents and other reasons increased from 1989 onwards, and an S. scabiei outbreak was recorded since 1993. The infestation spread from the southern to the northern regions of Yokohama. The total number of raccoon dogs rescued annually peaked in 1995 and declined thereafter. The number of masked palm civets (Paguma larvata) rescued gradually increased with a decline in the number of raccoon dogs rescued. In the present study, we revealed the epidemiology of S. scabiei infestation in the raccoon dog. The outbreak might be induced by the increased population density, and the infestation spread immediately from the southern to the northern regions of Yokohama since 1993. Further, the population of masked palm civets may have increased due to the decrease in the population of the raccoon dog. Copyright © 2012 Elsevier B.V. All rights reserved.

Full Text Available Background: Studies assessing the prevalence of reproductive morbidity among males in India have chiefly focused on prevalence of Reproductive Tract Infections/Sexually Transmitted Infections (RTIs/STIs among males attending Sexually Transmitted Disease clinics, blood donors and other selected population groups, with only few focused on the magnitude and the type of reproductive morbidity amongst Indian males at community level. Objective: To estimate prevalence of reproductive morbidity including (RTIs/STIs among males in the age group of 20-50 years residing in an urban slum of Delhi. Methods: Out of 268 males in the targeted age group, selected by systematic random sampling, residing in an urban sum of Delhi, 260 males were subjected to clinical examination and laboratory investigations for diagnosis of reproductive morbidity. Laboratory investigations were done for diagnosis of Hepatitis B and C, Syphilis, Gonorrhoea, Non gonococcal urethritis and urinary tract infection. Results: A total of 90 (33.6% of 268 study subjects reported one or more perceived symptoms of reproductive tract / sexual morbidity in last six months. Overall reproductive morbidity based on clinical and laboratory diagnosis was present in 76 (29.2% study subjects and of this sexually acquired morbidity accounted for 21.2% cases. Hepatitis B was most common (10.3% reproductive morbidity followed by Urinary Tract Infection (5.0%, scabies (3.5% and congenital anomalies (3.5%. Conclusion: High prevalence of reproductive morbidity (29.2% amongst males in an urban slum highlights the need for more studies in different settings. There is a need for developing interventions in terms of early diagnosis and treatment and prevention.

To describe the problems faced by children during separation from their imprisoned mothers, and evaluate the health of children who accompanied their mothers into prison. A prospective observational study. Welikada Prison, Colombo, Sri Lanka. 200 randomly selected mothers who had left their children at home were interviewed using a questionnaire. During a period of 8 months 30 children living with their mothers in prison underwent physical and developmental examination and tuberculin testing. The living conditions within the prison were evaluated. During 18 months from January 1999, 4089 women were imprisoned. 88% were remanded, 20% awaited trial for more than one year in prison. 2416 were mothers. 1411 had at least one child under 12 years of age. The 200 mothers interviewed had 262 children under 12 years at home. Their care arrangements were: a relative (69%), father (16%), older sibling (4%), religious organisation (2.7%), neighbour (1.3%). None had received social services support. 70 children accompanied mothers into prison. In the 30 children followed up regularly 23% had scabies, 10% pediculosis, and 7% impetigo. No severe malnutrition was found and screening for tuberculosis was negative. 70% were breastfed. The child-friendly dormitory was inadequate to accommodate all children. Care arrangements and schooling were affected and no counselling services were provided during the imprisoned mothers' absence. The children within the prison enjoyed close bonds with the mothers and their physical needs were met. The child's best interest had not always been considered by court when deciding on custody during the mothers' imprisonment.

Pandanus odoratissimus Linn. (family: Pandanaceae) is traditionally recommended by the Indian Ayurvedic medicines for treatment of headache, rheumatism, spasm, cold/flu, epilepsy, wounds, boils, scabies, leucoderma, ulcers, colic, hepatitis, smallpox, leprosy, syphilis, and cancer and as a cardiotonic, antioxidant, dysuric, and aphrodisiac. It contains phytochemicals, namely, lignans and isoflavones, coumestrol, alkaloids, steroids, carbohydrates, phenolic compounds, glycosides, proteins, amino acids as well as vitamins and nutrients, and so forth. It is having immense importance in nutrition. A 100 g edible Pandanus pericarp is mainly comprised of water and carbohydrates (80 and 17 g, resp.) and protein (1.3 mg), fat (0.7 mg), and fiber (3.5 g). Pandanus fruits paste provides 321 kilocalories, protein (2.2 g), calcium (134 mg), phosphorus (108 mg), iron (5.7 mg), thiamin (0.04 mg), vitamin C (5 mg), and beta-carotene (19 to 19,000 μg) (a carotenoid that is a precursor to vitamin A). Pandanus fruit is an important source of vitamins C, B1, B2, B3, and so forth, usually prepared as a Pandanus floured drink. Traditional claims were scientifically evaluated by the various authors and the phytochemical profile of plant parts was well established. The methods for analytical estimations were developed. However, there is paucity of systematic compilation of scientifically important information about this plant. In the present review we have systematically reviewed and compiled information of pharmacognostic, ethnopharmacology, phytochemistry, pharmacology, nutritional aspects, and analytical methods. This review will enrich knowledge leading the way into the discovery of new therapeutic agents with improved and intriguing pharmacological properties.

The taxonomy, life cycle and pathology of Sarcoptes scabiei and Notoedres cati (Acarina, Sarcoptidae: A review in a Fennoscandian wildlife perspective

Full Text Available Mites constitute an old cosmopolitan group, abundant in various terrestrial and aquatic habitats of considerable environmental variations. The majority of mites are free-living, whereas some have evolved parasitic relationships with a variety of animals either as endo- or ectoparasites. The ectoparasitic and skin burrowing Sarcoptes scabiei and Notoedres cati, cause sarcoptic and notoedric mange among a variety of mammalian species, including humans. In a non-adequate host these mites lead to pseudo-scabies which is often self-curable. The aim of this review is to provide an overview of recent knowledge on the taxonomy, life cycles and pathology of these two mites, which are of relevance to Fennoscandian wildlife, by considering knowledge on transmission vectors, host immunology, and some documented outbreaks. These mites affect the health and survival of mammals in four ways; 1 skin tissue damages, 2 loss of body fluids, 3 allergic reactions and 4 secondary bacterial infections. A short-term effect of outbreaks is usually high mortality, and long-term effects vary from extinction to biased population structure to no effect at all. Red foxes are generalist predators that are important end-hosts for mites that develop disease depending on their immunity status, and transmit mites to other hosts. Outbreaks of mange may possibly have ecological consequences on a wider scale. In an endangered species, like the arctic fox or Eurasian lynx, loss of only a few individuals can be critical. It might be wise for management authorities to develop emergency plans to minimize consequences of outbreaks of sarcoptic or notoedric mange in threatened species such as the arctic fox and the lynx.

Hierarchy and molecular properties of house dust mite allergens

Directory of Open Access Journals (Sweden)

Wayne R. Thomas

2015-10-01

Full Text Available The allergenic load of house dust mite allergy is largely constituted by a few proteins with a hierarchical pattern of allergenicity. The serodominant specificities are the group 1&2 and the group 23 faecal allergens. The collective IgE binding to the group 1&2 allergens can measure unequivocal HDM sensitisation better than HDM extracts although discrepancies have been found in regions with complex acarofauna suggesting a need to investigate the specificity with allergen components. The group 4, 5, 7&21 allergens that each induce responses in about 40% of subjects are mid-tier allergens accounting for most of the remaining IgE binding. Their titres are proportional to the concomitant responses to Der p1&2. Group 2 allergen variants have different antibody binding. Body proteins only occasionally induce sensitisation although a higher prevalence of binding by atopic dermatitis patients provides a new avenue of research. A broad spectrum of IgE binding has been associated with diverse symptoms but not with the severity of asthma which is associated with low IgG antibody. Some allergens such as the group 14 large lipid binding proteins and the recently described proteins Der f 24–33, need further investigation but with the cognoscence that other denominated allergens have been found to be minor sensitisers by comparative quantitative analyses. Scabies is a confounder for diagnosis with extracts, inducing cross-reactive antibodies with Der p 4&20 as is seafood allergy with cross reactivity to Der p 10 a minor HDM allergen. The HDM genome sequence can now be used to verify allelic and paralogous variations.

Internationally adopted children may suffer from different pathologies, including infectious diseases contracted in the country of origin. We evaluated the frequency of infectious diseases that may disseminate from adoptees to adoptive families on their arrival in France. All children who attended the clinic for international adoption in Clermont-Ferrand from January 2009 through to December 2011 were eligible for inclusion in the study. Standardized medical records dedicated to international adoption were retrospectively reviewed for demographic data, clinical diagnosis, and biological and radiological results. Data were completed by phone interviews with adoptive families after informed consent. One hundred and forty-two medical records were retrospectively reviewed and 86% of families agreed to be interviewed. One hundred and seventy-one potentially transmissible infections were diagnosed in 142 children, 12% (n = 20) of which were transmitted to adoptive families. Most of these infections were benign and transmission was restricted to the close family. Tinea was diagnosed in 44 adoptees and transmitted in 15 cases. Panton Valentine leukocidin producing methicillin-sensitive S. aureus (MSSA) was transmitted to an adoptive father who required hospitalization for bursitis. Transmission also occurred for CMV (n = 1), hepatitis A (n = 1), giardiasis (n = 1), scabies (n = 1), Moluscum (n = 2) and pediculosis (n = 2). Two cases of chronic hepatitis B and latent tuberculosis were diagnosed without subsequent transmission. In conclusion, infectious diseases are common in internationally adopted children and should be detected shortly after arrival to avoid transmission. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

The purpose of this study was to assess the incidence of medical illness among members of trekking groups in the Nepal Himalaya. The design was a cohort study using interview and clinical examination by a single physician. The setting was the Manaslu area in the central Nepal Himalaya along a 22-day trekking route with elevations ranging from 487 m to 5100 m. Subjects were 155 members of commercial trekking groups: 102 Nepali porters, 31 Nepali trek staff, and 22 Western trekkers. We found that medical problems occurred in 45% of party members. The porter cohort contained the highest diversity and severity of illness. The relatively larger porter cohort experienced 77% of the medical problems recorded compared with 17% among Western trekkers and 6% among trek staff. The incidence of medical problems was not significantly different in the porter staff (52%) and Western trekkers (55%) and was significantly lower for the trek staff (13%). High-altitude pharyngitis/bronchitis was the most common illness in the party (12%) followed by acute mountain sickness (8%) and gastroenteritis (6%). Other conditions included anxiety (3%), cellulitis (3%), scabies (3%), snow blindness (3%), acute alcohol intoxication (2%), conjunctivitis (2%), fever (2%), lacerations (2%), and hemorrhoids (1%). Illness with infectious etiologies comprised 33% of the medical problems. The incidence of altitude illness was not significantly less in the Nepali porter staff than in the Western trekkers. Evacuation was required in 5% of party members, all from the porter group. This study should alert expedition medical providers and trip leaders of the need to be observant for and prepared to treat the frequent and diverse medical problems among the porter staff in their party, in addition to the Western members. Medical problems are common in remote mountainous areas, indicating that trip physicians should be experienced in primary care.

Full Text Available Abstract Background Gap junctions increase in size and abundance coincident with parturition, forming an intercellular communication network that permits the uterus to develop the forceful, coordinated contractions necessary for delivery of the fetus. Lindane, a pesticide used in the human and veterinary treatment of scabies and lice as well as in agricultural applications, inhibits uterine contractions in vitro, inhibits myometrial gap junctions, and has been associated with prolonged gestation length in rats. The aim of the present study was to investigate whether brief exposures to lindane would elicit sustained inhibition of rat uterine contractile activity and myometrial gap junction intercellular communication. Methods To examine effects on uterine contraction, longitudinal uterine strips isolated from late gestation (day 20 rats were exposed to lindane in muscle baths and monitored for changes in spontaneous phasic contractions during and after exposure to lindane. Lucifer yellow dye transfer between myometrial cells in culture was used to monitor gap junction intercellular communication. Results During a 1-h exposure, 10 micro M and 100 micro M lindane decreased peak force and frequency of uterine contraction but 1 micro M lindane did not. After removal of the exposure buffer, contraction force remained significantly depressed in uterine strips exposed to 100 micro M lindane, returning to less than 50% basal levels 5 h after cessation of lindane exposure. In cultured myometrial myocytes, significant sustained inhibition of Lucifer yellow dye transfer was observed 24 h after lindane exposures as brief as 10 min and as low as 0.1 micro M lindane. Conclusion Brief in vitro exposures to lindane have long-term effects on myometrial functions that are necessary for parturition, inhibiting spontaneous phasic contractions in late gestation rat uterus and gap junction intercellular communication in myometrial cell cultures.

Scabies, or mange as it is called in animals, is an ectoparasitic contagious infestation caused by the mite Sarcoptes scabiei. Sarcoptic mange is an important veterinary disease leading to significant morbidity and mortality in wild and domestic animals. A widely accepted hypothesis, though never substantiated by factual data, suggests that humans were the initial source of the animal contamination. In this study we performed phylogenetic analyses of populations of S. scabiei from humans and from canids to validate or not the hypothesis of a human origin of the mites infecting domestic dogs. Mites from dogs and foxes were obtained from three French sites and from other countries. A part of cytochrome c oxidase subunit 1 (cox1) gene was amplified and directly sequenced. Other sequences corresponding to mites from humans, raccoon dogs, foxes, jackal and dogs from various geographical areas were retrieved from GenBank. Phylogenetic analyses were performed using the Otodectes cynotis cox1 sequence as outgroup. Maximum Likelihood and Bayesian Inference analysis approaches were used. To visualize the relationship between the haplotypes, a median joining haplotype network was constructed using Network v4.6 according to host. Twenty-one haplotypes were observed among mites collected from five different host species, including humans and canids from nine geographical areas. The phylogenetic trees based on Maximum Likelihood and Bayesian Inference analyses showed similar topologies with few differences in node support values. The results were not consistent with a human origin of S. scabiei mites in dogs and, on the contrary, did not exclude the opposite hypothesis of a host switch from dogs to humans. Phylogenetic relatedness may have an impact in terms of epidemiological control strategy. Our results and other recent studies suggest to re-evaluate the level of transmission between domestic dogs and humans.

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

Full Text Available BACKGROUND Skin diseases in pediatric age group are common all over the world. Pediatric dermatoses require separate view from adult dermatoses as there are differences in their clinical presentation and treatment. OBJECTIVE The aim of our study was to determine the prevalence of pediatric dermatoses attending our tertiary care center. MATERIALS AND METHODS This was a cross-sectional study conducted in 100 consecutive children with dermatoses between 5-14 years of age attending dermatology outpatient department at Vinayaka Missions Kirupananda Variyar medical college, Salem. The study was conducted over a period of 6 months from February 2016 to August 2016. Demographic parameters, detailed history, clinical features and diagnosis were recorded and analyzed. RESULTS In our short term study, we examined 100 pediatric cases with 106 dermatoses. The incidence of infections and infestations (43.39% was more prevalent in our study. The most common non-infectious dermatoses in our study was insect bite reactions (17.9%. Dermatitis and eczema (9.39%, disorders of sweat and sebaceous glands (6.6%, pigmentary disorders (5.66%, disorders of hair and nails (3.77%, genetic disorders (2.88%, immune and allergic disorders (2.8%, psoriasis (2.8%, nutritional disorders (0.9%, Polymorphic light eruption (0.9%, pearly penile papule (0.9%, aphthous ulcer (0.9% and pityriasis rosea (0.9% were the other dermatoses seen in the study.CONCLUSION Fungal infections (tinea versicolor and tinea corporis, scabies and insect bite reactions were the common dermatoses observed in our study. Most of the pediatric patients attending our hospital came from rural areas belonging to low socioeconomic strata. Health education, proper sanitation and improved nutrition will help to reduce the incidence of pediatric dermatoses.

Full Text Available Background: Cutaneous disorders during HIV infection are numerous and skin is often the first and only organ affected during most of the course of HIV disease. Some Cutaneous disorders reflect the progression of HIV disease; though the relation is still controversial. Aims : The objective of this study, conducted at a tertiary care centre in Bastar, Jagdalpur, is to estimate the status of cutaneous manifestation in HIV-infected patients and its relationship with CD4 cell counts. Methods: We enrolled 137 HIV positive subjects. Demographic information such as age, gender, weight, height, socioeconomic status, and educational status were recorded. Laboratory parameter (CD4 counts and treatment regimen were noted. Patients were examined for skin disorders by a dermatologist. Data were analyzed using chi-square test for categorical variables. Results: Majority of the patients were from rural area (65.69% and belonged to a low socioeconomic and educational status. 30.65% of the patients were housewives, 23.35% drivers, and 16.78% labourers. Predominant mode of transmission was heterosexual contact (94.16%. Most common HIV-related dermatological manifestations were seborrheic dermatitis (74.16%, xerosis (52.5%, generalized skin hyperpigmentation 56 (46.67%, onychomycosis 53 (44.16%, pruritic papular eruption 27 (22.5%, oral candidiasis 21 (17.5%, photo dermatitis 21 (17.5%, and scabies 4 (3.33%. Significant correlation with low CD4+ cell counts was found for oral candidiasis (P < 0.0001 and Kaposi′s sarcoma ( P = 0.03, while other disorders such as seborrheic dermatitis ( P = 0.22, xerosis ( P = 0.25, and onychomycosis (P = 0.08 were not statistically significant. Conclusion : This study showed high prevalence of dermatological manifestations in HIV-infected subjects, and they occur more frequently with progression of HIV and decline in immune functions. Therefore, early diagnosis and management of skin disorders can improve the quality of life of

A measure of South Africa's health care.

Science.gov (United States)

de Selincourt, K

Nurses provide the bulk of health care in South Africa. For example, in 1 of the biggest and poorest townships Khayelitsha, nurses treat malnourished mothers and children and offer primary health care services. Physicians tend to work in township clinics on a part-time basis and supervise nurse-advised treatments over the telephone. Most physicians do not speak the language of the people living in the township which is Xhosa. Thus they often depend on a nurse to serve as interpreter for Xhosa-speaking patients which takes the nurse away from her duties. Some clinics never receive physician supervision or services. Nurses spend much of their time sharing their skills and knowledge with clients. Nutrition workers and other staff back up nurses at the clinics. They sometimes are mothers whose children were at one time malnourished. Since they have the basic skills and knowledge, clinic staff provide treatment for straightforward conditions such as scabies. Nurses working in hospital in Khayelitsha also have many responsibilities. For example, they do the initial psychiatric assessment and decide whether to send a patient immediately to Valkenburg Psychiatric Hospital or to schedule the patient for an appointment with the physician at the satellite psychiatric clinic at Khayelitsha Hospital where psychiatrists come only twice/week. They sometimes make home visits which results in them also providing primary care. Unlike nurses not working in the hospital, the nurses at the hospital have good medical support. Both black and white nurses in South Africa work in the same clinics despite the country's policy of separateness. A shortage of nurses is 1 reason for this integration. Black nurses still encounter discrimination when applying for jobs and, until recently, made less money for the same work than white nurses.

Full Text Available OBJECTIVE: To establish priorities for zoonoses surveillance, prevention, and control in Bogotá, Colombia. METHODS: A Delphi panel of experts in veterinary and human medicine was conducted using a validated prioritization method to assess the importance of 32 selected zoonoses. This exercise was complemented by a questionnaire survey, using the knowledge, attitudes, and practices (KAP methodology, administered in 19 districts of Bogotá from September 2009 to April 2010 to an at-risk population (workers at veterinary clinics; pet shops; butcher shops; and traditional food markets that sell poultry, meat, cheese, and eggs. A risk indicator based on level of knowledge about zoonoses was constructed using categorical principal component and logistic regression analyses. RESULTS: Twelve experts participated in the Delphi panel. The diseases scored as highest priority were: influenza A(H1N1, salmonellosis, Escherichia coli infection, leptospirosis, and rabies. The diseases scored as lowest priority were: ancylostomiasis, scabies, ringworm, and trichinellosis. A total of 535 questionnaires were collected and analyzed. Respondents claimed to have had scabies (21%, fungi (8%, brucellosis (8%, and pulicosis (8%. Workers with the most limited knowledge on zoonoses and therefore the highest health risk were those who 1 did not have a professional education, 2 had limited or no zoonoses prevention training, and 3 worked in Usme, Bosa, or Ciudad Bolívar districts. CONCLUSIONS: According to the experts, influenza A(H1N1 was the most important zoonoses. Rabies, leptospirosis, brucellosis, and toxoplasmosis were identified as priority diseases by both the experts and the exposed workers. This is the first prioritization exercise focused on zoonoses surveillance, prevention, and control in Colombia. These results could be used to guide decision-making for resource allocation in public health.OBJETIVO: Establecer prioridades en la vigilancia, la prevención y

Full Text Available BACKGROUND: In its first 8 years, the Global Programme to Eliminate Lymphatic Filariasis (GPELF achieved an unprecedentedly rapid scale-up: >1.9 billion treatments with anti-filarial drugs (albendazole, ivermectin, and diethylcarbamazine were provided via yearly mass drug administration (MDA to a minimum of 570 million individuals living in 48 of the 83 initially identified LF-endemic countries. METHODOLOGY: To assess the health impact that this massive global effort has had, we analyzed the benefits accrued first from preventing or stopping the progression of LF disease, and then from the broader anti-parasite effects ('beyond-LF' benefits attributable to the use of albendazole and ivermectin. Projections were based on demographic and disease prevalence data from publications of the Population Reference Bureau, The World Bank, and the World Health Organization. RESULT: Between 2000 and 2007, the GPELF prevented LF disease in an estimated 6.6 million newborns who would otherwise have acquired LF, thus averting in their lifetimes nearly 1.4 million cases of hydrocele, 800,000 cases of lymphedema and 4.4 million cases of subclinical disease. Similarly, 9.5 million individuals--previously infected but without overt manifestations of disease--were protected from developing hydrocele (6.0 million or lymphedema (3.5 million. These LF-related benefits, by themselves, translate into 32 million DALYs (Disability Adjusted Life Years averted. Ancillary, 'beyond-LF' benefits from the >1.9 billion treatments delivered by the GPELF were also enormous, especially because of the >310 million treatments to the children and women of childbearing age who received albendazole with/without ivermectin (effectively treating intestinal helminths, onchocerciasis, lice, scabies, and other conditions. These benefits can be described but remain difficult to quantify, largely because of the poorly defined epidemiology of these latter infections. CONCLUSION: The GPELF has

The Brazilian crops mangoes and apples has expanding in the last years. However, tropical fruits crops are susceptible to infection that harms the crop yield. The control of these diseases is made through fungicides such as prochloraz which possesses protecting eradicating action by controlling anthracnose in mangoes and scabies in apples. Agrochemicals are of great importance in the agriculture considering the of relationship cost/benefit. However they may cause a series of problems in the ecosystem, being the levels of agrochemicals residues in fruits one of these factors. The aim of this work was to evaluate the prochloraz levels in mangoes treated in both stages of pre and post harvest, and in apples treated in the pre harvest. In the treatment of the mangoes, the interaction, fungicide with the gamma radiation with dose of 1,0 kGy, was used to induce prochloraz degradation. Treated post harvest mangoes were stored, at 12 deg C during 21 days. The results showed that the prochloraz did not present reduction in the residual levels of the mangoes after 21 day storage, that is the safe period established by the Brazilian legislation on agrochemicals, in treated mangoes. The refrigerated storage (12 deg C) and the gamma radiation also did not contribute to the degradation of the fungicide in mangoes. In average the concentration of the fungicide prochloraz in the peels (bar X = 1,64 mug/g) was higher than in the mangoes pulp (bar x = 0,06 mug/g), which allows the consumption of this fruit, since the peel is always discarded. The degradation product, formed in peels of mangoes in fruits treated in the pre and post harvest was the metabolite BIS 44596; for mangoes treated in the pre-post harvest the metabolite formed was the BIS 445186. Both metabolites were found in very low levels, confirming that occurs degradation of the fungicide in mangoes. In apples treated with the prochloraz, reduction of 500/0 in the levels. (author)

Sarcoptic mange is a contagious skin disease caused by the mite Sarcoptes scabiei, affecting different mammalian species worldwide including the Iberian ibex (Capra pyrenaica), in which mortalities over 90 % of the population have been reported. No efficient diagnostic methods are available for this disease, particularly when there are low mite numbers and mild or no clinical signs. In this study, three enzyme-linked immunosorbent assays (ELISA) developed for dog (ELISA A), Cantabrian chamois (Rupicapra pyrenaica parva) (ELISA B) and Alpine chamois (Rupicapra rupicapra) (ELISA C), were evaluated to detect specific antibodies (IgG) to sarcoptic mange in Iberian ibex sera. Serum samples from 131 Iberian ibexes (86 healthy and 45 scabietic) were collected from 2005 to 2012 in the Sierra Nevada Natural and National Parks (southern Spain). Based on visual inspection, ibexes were classified into one of three categories, namely healthy (without scabietic compatible lesions), mildly affected (skin lesions over less than 50 % of the body surface) and severely affected (skin lesions over more than 50 % of the body surface). The optimal cut-off point, specificity, sensitivity and the area under the curve (AUC) were calculated, and the agreement between tests was determined. Moreover, differences in the optical density (OD) related to scabies severity have been evaluated for the best test. ELISA C showed better performance than the two other tests, reaching higher values of sensitivity (93.0 %) and specificity (93.5 %) against the visual estimation of the percentage of affected skin, chosen as the gold standard. Significantly higher concentrations of specific antibodies were observed with this test in the mildly and severely infested ibexes than in healthy ones. Our results revealed that ELISA C was an optimal test to diagnose sarcoptic mange in the Iberian ibex.

Full Text Available The increasing number of refugees seeking asylum in Europe in recent years poses new challenges for the healthcare systems in the destination countries. The goal of the study was to describe the evolution of medical problems of asylum seekers at a tertiary care centre in Switzerland.At the University Hospital Basel, we compared all asylum seekers during two 1-year time periods in 2004/05 and 2014/15 concerning demographic characteristics and reasons for referrals and hospitalizations.Hundred ninety five of 2'544 and 516 of 6'243 asylum seekers registered at the national asylum reception and procedure centre Basel were referred to the University Hospital Basel in 2004/05 and 2014/15, and originated mainly from Europe (62.3%, mainly Turkey and Africa (49.1%, mainly Eritrea, respectively. Median age was similar in both study periods (26.9 and 26.2 years. Infectious diseases in asylum seekers increased from 22.6% to 36.6% (p<0.001 and were the main reasons for hospitalizations (33.3% of 45 and 55.6% of 81 hospitalized patients, p = 0.017 in 2004/05 compared to 2014/15. The leading infectious diseases in hospitalized patients were tuberculosis (n = 4 and bacterial skin infections (n = 2 in 2004/05; Malaria (n = 9, pneumonia (n = 6, Chickenpox (n = 5, other viral infections (n = 5 and bacterial skin infections (n = 5 in 2014/15. Infectious diseases like malaria, cutaneous diphtheria, louseborne-relapsing fever or scabies were only found in the second study period. Almost one third of the admitted asylum seekers required isolation precautions with median duration of 6-9.5 days in both study periods.The changing demography of asylum seekers arriving in Switzerland in the current refugee crisis has led to a shift in disease patterns with an increase of infectious diseases and the re-emergence of migration-associated neglected infections. Physicians should be aware of these new challenges.

A systematic examination of 391 children at school age was performed, at age from 1st to 4th grade of grammar school, among which there was 183 boys and 208 girls. Examination was done by the responsible pediatric service of the Primary health care Center Sokolac with help of the humanitarian organization World Vision from Taiwan. The goal of the examination was to get an insight in the general health state of this population, including the risk factor for development of cardiovascular disease (CVD), to suggest appropriate preventive measures, and determine further justification of these examinations within the new organization of health care in RS and B&H. Satisfactory hygiene status of these children, eradication of lousiness and scabies, high percentage of vaccinated children (95%) according to current national program, evaluation of most common congenital anomalies speaks in favor of adequate pediatric care at early age. Higher percent of weak vision (10.23%), "flat feet" (36.57%) and chronic tonsillitis (34.52%), as well as occasional cases of herniations, criptochrism, spine and thorax deformities, and one hearth anomaly indicates on insufficient systematic examination "within critical period" from 3 to 7 years of age. Most often pathological substrate during the examination was caries (69.30%) which indicated the poor prevention of this illness. Percentage of 10.74% obese children and 8.95% children with systolic blood pressure above 95 for this age justify the attitude of WHO on early prevention of CVD. The necessity of pediatric care is indicated at age up to 7 years and regular systematic examinations of the school children according to the program of Health Care Fund by the consultancy pediatric service, as well importance of cooperation with the teams of family medicine. Urgent prevention and treatment of caries is recommended at the referral health care centers and more strict control by the responsible Health Care Fund of RS for the signed contracts

Cutinase from the fungus Fusarium solani pisi is a lipolytic enzyme able to hydrolyze both aggregated and soluble substrates. It therefore provides a powerful tool for probing the mechanisms underlying lipid hydrolysis. Lipolytic enzymes have a catalytic machinery similar to those present in serine proteinases. It is characterized by the triad Ser, His, and Asp (Glu) residues, by an oxyanion binding site that stabilizes the transition state via hydrogen bonds with two main chain amide groups, and possibly by other determinants. It has been suggested on the basis of a covalently bond inhibitor that the cutinase oxyanion hole may consist not only of two main chain amide groups but also of the Ser42 O gamma side chain. Among the esterases and the serine and the cysteine proteases, only Streptomyces scabies esterase, subtilisin, and papain, respectively, have a side chain residue which is involved in the oxyanion hole formation. The position of the cutinase Ser42 side chain is structurally conserved in Rhizomucor miehei lipase with Ser82 O gamma, in Rhizopus delemar lipase with Thr83 O gamma 1, and in Candida antartica B lipase with Thr40 O gamma 1. To evaluate the increase in the tetrahedral intermediate stability provided by Ser42 O gamma, we mutated Ser42 into Ala. Furthermore, since the proper orientation of Ser42 O gamma is directed by Asn84, we mutated Asn84 into Ala, Leu, Asp, and Trp, respectively, to investigate the contribution of this indirect interaction to the stabilization of the oxyanion hole. The S42A mutation resulted in a drastic decrease in the activity (450-fold) without significantly perturbing the three-dimensional structure. The N84A and N84L mutations had milder kinetic effects and did not disrupt the structure of the active site, whereas the N84W and N84D mutations abolished the enzymatic activity due to drastic steric and electrostatic effects, respectively.

Full Text Available Introduction: The Sexually transmitted diseases (STDs are a global health problem of great magnitude. The pattern of STDs differs from country to country and from region to region. The increased risk of the transmission of HIV is known to be associated with the presence of sexually transmitted diseases (STDs and despite the presence of the National STD Control Program in India the number of people with STDs remains high. Aim: The aim of our study was to study the profile of patients in a STD clinic in North India and to study various sexually transmitted infections in both male and female patients. Material and Methods: A prospective study of the patients attending STD clinic in a district hospital in North India from December 2009 to December 2012 was done. A total of 2700 patients attending the STDclinic in three years from December 2009 to December 2012 were taken up for the study. Results: The commonest sexually transmitted infection in males was herpes genitalis (30% followed by 20% cases of genital warts. 10% patients had gonorrhoea, genital molluscum contagiosum, syphilis and genital scabies each and 5% patients had nongonococcal urethritis. Only 5% of the total patients had chancroid, donovanosis and LGV. The commonest sexually transmitted infection in females was vaginal discharge seen in 40% patients, lower abdominal pain in 20% patients, herpes genitalis in 15% patients followed by 20% cases of genital warts and syphilis each. Genital molluscum contagiosum was seen in 5% patients only. Conclusions: The treatment of STD’s is important as both non-ulcerative and ulcerative STDs increase the susceptibility to or transmissibility of HIV infection and as such, an increase in STD prevalence as revealed by clinic attendance in this study was bound to facilitate the spread of HIV/AIDS. Perhaps it is high time health planners adopted a more aggressive and result oriented HIV/AIDS/STD awareness campaign strategy.

The Brazilian crops mangoes and apples has expanding in the last years. However, tropical fruits crops are susceptible to infection that harms the crop yield. The control of these diseases is made through fungicides such as prochloraz which possesses protecting eradicating action by controlling anthracnose in mangoes and scabies in apples. Agrochemicals are of great importance in the agriculture considering the of relationship cost/benefit. However they may cause a series of problems in the ecosystem, being the levels of agrochemicals residues in fruits one of these factors. The aim of this work was to evaluate the prochloraz levels in mangoes treated in both stages of pre and post harvest, and in apples treated in the pre harvest. In the treatment of the mangoes, the interaction, fungicide with the gamma radiation with dose of 1,0 kGy, was used to induce prochloraz degradation. Treated post harvest mangoes were stored, at 12 deg C during 21 days. The results showed that the prochloraz did not present reduction in the residual levels of the mangoes after 21 day storage, that is the safe period established by the Brazilian legislation on agrochemicals, in treated mangoes. The refrigerated storage (12 deg C) and the gamma radiation also did not contribute to the degradation of the fungicide in mangoes. In average the concentration of the fungicide prochloraz in the peels (bar X = 1,64 mug/g) was higher than in the mangoes pulp (bar x = 0,06 mug/g), which allows the consumption of this fruit, since the peel is always discarded. The degradation product, formed in peels of mangoes in fruits treated in the pre and post harvest was the metabolite BIS 44596; for mangoes treated in the pre-post harvest the metabolite formed was the BIS 445186. Both metabolites were found in very low levels, confirming that occurs degradation of the fungicide in mangoes. In apples treated with the prochloraz, reduction of 500/0 in the levels. (author)

Full Text Available Strongyloides seroprevalence is hyper-endemic in many Australian Aboriginal and Torres Strait Islander communities, ranging from 35-60%. We report the impact on Strongyloides seroprevalence after two oral ivermectin mass drug administrations (MDAs delivered 12 months apart in a remote Australian Aboriginal community.Utilizing a before and after study design, we measured Strongyloides seroprevalence through population census with sequential MDAs at baseline and month 12. Surveys at months 6 and 18 determined changes in serostatus. Serodiagnosis was undertaken by ELISA that used sonicated Strongyloides ratti antigen to detect anti-Strongyloides IgG. Non-pregnant participants weighing ≥15 kg were administered a single 200 μg/kg ivermectin dose, repeated after 10-42 days if Strongyloides and/or scabies was diagnosed; others followed a standard alternative algorithm. A questionnaire on clinical symptoms was administered to identify adverse events from treatment and self-reported symptoms associated with serostatus.We surveyed 1013 participants at the baseline population census and 1060 (n = 700 from baseline cohort and 360 new entrants at month 12. Strongyloides seroprevalence fell from 21% (175/818 at baseline to 5% at month 6. For participants from the baseline cohort this reduction was sustained at month 12 (34/618, 6%, falling to 2% at month 18 after the second MDA. For new entrants to the cohort at month 12, seroprevalence reduced from 25% (75/297 to 7% at month 18. Strongyloides positive seroconversions for the baseline cohort six months after each MDA were 2.5% (4/157 at month 6 and 1% at month 18, whilst failure to serorevert remained unchanged at 18%. At 12 months, eosinophilia was identified in 59% of baseline seropositive participants and 89% of seropositive new entrants, compared with 47%baseline seronegative participants and 51% seronegative new entrants. Seropositivity was not correlated with haemoglobin or any self-reported clinical

Thevetia peruviana (Pers.) K. Schum or Cascabela peruviana (L.) Lippold (commonly known as ayoyote, codo de fraile, lucky nut, or yellow oleander), native to Mexico and Central America, is a medicinal plant used traditionally to cure diseases like ulcers, scabies, hemorrhoids and dissolve tumors. The purpose of this study was to evaluate the cytotoxic, antiproliferative and apoptotic activity of methanolic extract of T. peruviana fruits on human cancer cell lines. The cytotoxic activity of T. peruviana methanolic extract was carried out on human breast, colorectal, prostate and lung cancer cell lines and non-tumorigenic control cells (fibroblast and Vero), using the MTT assay. For proliferation and motility, clonogenic and wound-healing assays were performed. Morphological alterations were monitored by trypan blue exclusion, as well as DNA fragmentation and AO/EB double staining was performed to evaluate apoptosis. The extract was separated using flash chromatography, and the resulting fractions were evaluated on colorectal cancer cells for their cytotoxic activity. The active fractions were further analyzed through mass spectrometry. The T. peruviana methanolic extract exhibited cytotoxic activity on four human cancer cell lines: prostate, breast, colorectal and lung, with values of IC 50 1.91 ± 0.76, 5.78 ± 2.12, 6.30 ± 4.45 and 12.04 ± 3.43 μg/mL, respectively. The extract caused a significant reduction of cell motility and colony formation on all evaluated cancer cell lines. In addition, morphological examination displayed cell size reduction, membrane blebbing and detachment of cells, compared to non-treated cancer cell lines. The T. peruviana extract induced apoptotic cell death, which was confirmed by DNA fragmentation and AO/EB double staining. Fractions 4 and 5 showed the most effective cytotoxic activity and their MS analysis revealed the presence of the secondary metabolites: thevetiaflavone and cardiac glycosides. T. peruviana extract has

. Leptospirosis, which is endemic and identified as the top priority disease at the regional level, was never mentioned by any interviewed farmer. Farmers did not name any emerging infectious diseases as priorities. Instead, they identified endemic diseases (parasites, flu, coccidiosis, and scabies) as the most important. While animal disease priorities appear to differ widely between the targeted regions and countries, it also varies significantly between experts and farmers. Better targeted surveillance programmes may thus result in more rational and transparent allocation of resources, and thus enhanced food security, but may not directly match the needs of the local communities.

Full Text Available Introdução: A escabiose consiste em uma doença contagiosa causada pelo ácaro Sarcoptes scabie, parasita exclusivo da pele humana, transmitida pelo contato direto com pessoa infectada. Pode ocorrer em qualquer faixa etária, independente do sexo, etnia ou hábitos de higiene, sendo diagnosticada com base na história de coceira noturna, associada a lesões cutâneas. Em geral, há mais de um caso na mesma residência. Apresenta diversos diagnósticos diferenciais por ser essencialmente uma dermatite. Objetivo: Alertar para possibilidade de escabiose na comunidade. Metodologia: As informações contidas nesse relato foram obtidas por meio de consultas médicas, registros fotográficos, evolução, hipóteses diagnósticas e revisão de literatura. Relato de Caso: E.T.L.T, sexo feminino. Aos 21 dias de vida, mãe relata vermelhidão nas costas da paciente e ao exame físico observa-se eritema máculo papular na região de transição parieto-occipital do crânio. A conduta baseia-se em orientação quanto à lavagem de roupa de cama com sabão de coco, remoção de xampu e talco e observação do rash cutâneo. Treze dias depois, mãe refere piora das manchas vermelhas e aparecimento de lesões em tórax anterior e posterior, pescoço e face. Relata ainda, ter cachorro em casa e lesões semelhantes em seu próprio tórax e mamas antes mesmo de a criança nascer. A orientação foi mantida, além de ser receitado enxofre precipitado a 10% para a mãe e a 5% para a criança. Após cinco dias de tratamento, as manchas regrediram e a paciente voltou a ser amamentada. Conclusão: A escabiose continua a ser uma dermatose frequente, cujo tratamento em idade pediátrica se restringe aos “steps” para o diagnóstico correto, desinfecção dos fômites e uso de um bom escabicida, tanto para a criança quanto para seus cuidadores.

This study aims to monitor the prevalence of suppurative otitis media in remote Indigenous communities after introduction of 13-valent pneumococcal conjugate vaccine (PCV13) in October 2011. We previously reported a decline in suppurative OM following replacement of PCV7 by 10-valent pneumococcal Haemophilus influenzae protein D conjugate vaccine (PHiD-CV10) in October 2009. We continued regular surveillance in remote Indigenous communities between February 2010 and August 2013. This analysis reports the general health, otitis media (OM), nasopharyngeal (NP) carriage and middle ear microbiology in children less than 36 months of age who received a primary course of at least two doses of PHiD-CV10 or PCV13, and not more than one dose of another pneumococcal vaccine. Mean ages of 511 PHiD-CV10- and 140 PCV13-vaccinated children were 19 and 13 months, respectively. Most children received 3-dose non-mixed PCV schedules. At the time of assessment, general health was poor and prevalence of risk factors was high in both groups: overall, around 14% of children had scabies, 20% had impetigo, 59% had runny nose and 39% had cough. Average household size was 8 persons, and 60% of the mothers smoked. Bilaterally normal middle ears were detected in 10% and 7%, respectively. OM with effusion (OME), almost all bilateral, was diagnosed in 52% and 50%, any suppurative OM (acute OM or any tympanic membrane perforation [TMP]) in 37% and 41%, and TMP in 14% and 12%, respectively. Children in the PCV13 group had significantly less NP carriage of combined Streptococcus pneumoniae (Spn) and non-typeable Haemophilus influenzae (NTHi) (62% versus 51%) but significantly more polymicrobial (Spn and NTHi) middle ear cultures (12% versus 43%), and significantly less Staphylococcus aureus-positive middle ears (40% versus 7%). Although NP carriage of pneumococcal serotype 19A was low in the PCV13 group, serotypes 19F and 23F persist. The general health, particularly ear health, of little children

transmitted diseases are bacterial or viral in origin and present as a rash or ulcer. Impetigo is a bacterial infection which may present as a bullous eruption or as an erosion with a honey colored crust. Other bacterial infections include erythema chronicum migrans, folliculitis, and cellulitis. Fungal infections include the various forms of tinea and are usually treated with topical antifungals; if the infection is located in a hair-bearing area, systemic antifungals are necessary. Viral infections include warts, varicella, molluscum contagiosum, and herpes. Treatment varies from observation or antivirals for varicella to cryosurgery and topical imiquimod for warts. Finally, scabies and lice are infectious agents that can be treated with permethrin and pyrethrin solutions.

The most frequent underlying malignancies were lymphoma, adenocarcinomas of the upper digestive tract, and malignant neoplasms of the pancreas. The average age of the patients was 47.0 ± 16.9 years and the length of the disease since diagnosis was 13.7 months. The mortality rate was 75%. Paraneoplastic dermatoses are rare dermatologic entities that are difficult to diagnose. Surveillance is also hampered when patients do not have easy access to health care centers due to financial and geographical issues. However, when identified, they might facilitate the early diagnosis of an associated tumor and contribute to increase the surveillance of patients.Em um hospital público em Lima, Peru, 24 pacientes com 16 tipos de dermatoses paraneoplásicas foram identificados por meio de coleta de dados.

According to the World Health Organization (WHO), 80% of the world's population uses medicinal plants in the treatment of diseases and, in African countries, this rate is much higher. In recent years, however, medicinal plants have represented a primary health source for the pharmaceutical industry. No less than 400 compounds derived from plants are currently used in the preparation of drugs, such as vincristine and vinblastine used in the treatment of cancer. Nigerians still depend largely on crude herbal remedies or traditional medicine. They also use wild plants for cosmetics and perfumery. Some of these herbal remedies have been observed to be effective in certain skin diseases. The data were obtained from history questionnaires completed by patients at the Dermatology Clinic, Lagos State University Teaching Hospital (LASUTH), Ikeja, Lagos, Nigeria, and from oral interviews with vendors and prescribers of herbal preparations at major markets at Lagos and Ijebu-Ode in south-west Nigeria, between July 2004 and July 2006. Photographs of plants were taken at private residences at Lagos, Ibadan, and Ijebu-Ode in south-west Nigeria. A literature search was conducted on 38 of the plants. The data are presented in tabular form. Sixty-five per cent of patients had applied some form of herbal remedy before attending our clinic. The reasons for consultation included relapses, unsustained relief, incomplete resolution, and post inflammatory hyperpigmentation. Lesions for which herbs were successfully applied included infantile eczema and seborrhoiec dermatitis, atopic eczema, impetigo, impetiginized eczema, tinea capitis, scabies, erythema multiforme, leg ulcers, localized vitiligo, and sexually transmitted diseases. Partial relief was achieved in dermatophytoses, ichthyosis, leprosy, and systemic lupus erythematosus (SLE). Some forms of alopecia, onychomycosis, and vitiligo, as well as allergic dermatoses, were not improved by herbal medicines. The preparation of the

2015-01-15

Acalypha is the fourth largest genus of the Euphorbiaceae family with approximately 450-570 species. Several Acalypha species are used as medicinal plants in Africa and in the Mascarene Islands. Almost every part of the plant including the leaves, stem and roots are used as traditional remedies to treat and manage a panoply of ailments. However, there is no updated compilation of traditionally important medicinal plants from the Acalypha genus. The present review therefore, endeavors to provide for the first time an updated compilation of documented ethnopharmacological information in relation to the ethnomedicinal, ethnoveterinary, zoopharmacognosy, phytochemistry and biological activities of medicinal plants from the Acalypha genus which can subsequently open new perspectives for further pharmacological research. A literature search was performed on Acalypha species using ethnobotanical text books and scientific databases such as Pubmed, Scopus, EBSCO, Google Scholar and other web sources such as records from PROTA, PROSEA, and Botanical Dermatology Database. The Plant List, International Plant Name index and Kew Botanical Garden Plant name databases were used to validate scientific names. Plants from Acalypha genus are traditionally used in the treatment and/or management of diverse ailments such as diabetes, jaundice, hypertension, fever, liver inflammation, schistosomiasis, dysentery, respiratory problems including bronchitis, asthma and pheumonia as well as skin conditions such as scabies, eczema and mycoses. Approximately 124 species were listed in ethnobotanical studies with some botanical description and others mentioned from different web sources. However, only 40 species have been included in the present review due to the unavailability of ethnopharmacological data on the remaining species. Among the 40 cited species, 30 were traditionally used for the treatment and/or management of approximately 70 human diseases or health conditions. Two species

tubers (over 40 mm harvested in this season became nearly worthless because of the intensive occurrence of internal dark and scattered spots, associated to enlarged lenticels. HYDRA was the best variety in producing large potatoes, mainly in the dry season. In both seasons, however, most of the potatoes were lost for the market, due to the strong attack of common scab (Streptomyces scabies. TONDRA showed the greatest difference between yields of different seasons. Production of marketable tubers increased twice and that of large tubers, almost three times, in the rainy season. This variety had no trouble similar to that of the other ones and in the rainy season, its yield of large potatoes was not significantly lower than that of HANSA and HYDRA.

Soil biological functioning and proper agrotechnical management are of key importance in organic agriculture. Beneficial microbial inoculums are used either as plant strengthening products (psp) or also as plant protecting products (ppp). Question is, which type of microbes should be applied to certain soil-plant systems to improve yield or reduce the damage of soil-born plant pathogens? Objective of present study was to compare the effect of inoculums 1 (PPS) with plant growth promoting bacterium strains (PGPR) and inoculums 2 (TPB) with potential biocontrol-agents, including both fungi and bacteria in organic potato production. Field experiment was conducted at the Organic Research Station of the Szent István University (Babatpuszta, Hungary). Growth and quality of potato (Solanum tuberosum var. Demon) was studied in the two microbial treatments and control, in four replicates. The PPS inoculums included Pseudomonas protegens, Ps. jessenii and Strenotrophomonas maltophylia, with plant growth promoting (PGPR) effect. TPB inoculums consisted of Trichoderma hartianum, Pseudomonas putida and Bacillus subtilis strains with main biocontrol effects of fungal and bacterium combination. Strains were incubated for 24 hours at 28 oC in a rotary shaker (140 rpm/min) up till cell-number about 1010 cell.ml-1 in Nutrient broth substrate, and mixed to prepare combined inoculums. Each potato tuber was treated by 10 ml inoculums that was added to 100 ml water respectively with only water at the controls. Yield of potato (10 plants/plot) and tuber quality, i.e. the percentage ratio of scabbiness (Streptomyces scabies), Rhizoctonia solani, and Fusarium sp. infection was estimated. Abundance of total aerob and anaerob heterotrophs, total microscopic fungi, pseudomonads bacteria and some sporeforming microorganisms was assessed by the most probable number (MPN) method in soil samples, collected four times during vegetation.

Mercury (Hg) contamination was assessed in environment near an amalgamation gold recovery operation located at a small scale mining operation (Phanom Pha) in Phichit Province, Thailand. Total mercury (THg) concentrations was determined in water, sediment, bivalves in the aquatic environment and as dry deposition or atmospheric fallout on surface soil and leaves of Neem tree (Azadirachta indica Juss. var. siamensis Valeton) near the mining operation. THg in surface soil, Neem flowers (edible part) and rice grain in surrounding terrestrial habitat and with distance from the mining area were also evaluated for possible contamination. Potential environmental risks were evaluated using the hazard quotient equation. Hg analyses conducted in the aquatic habitat showed that THg in water, sediment and bivalves (Scabies cripata Gould) ranged from 0.4 to 4 microg L(-1), 96 to 402 microg kg(-1)dry weight (dw) and 15 to 584 microg kg(-1) wet weight (ww), respectively. High concentrations of THg in water, sediment and bivalves were observed in the receiving stream near the mining operation which was located near the Khao Chet Luk Reservoir. Whereas the THg concentration in water, sediment and bivalves from monitoring stations outside the gold mining operation (upstream and downstream), were considerably lower with the values of 0.4-0.8 microg L(-1), 96-140 microg kg(-1) dw and 88-658 microg kg(-1) dw, respectively. The elevated concentration of Hg found in the sediment near the mining operation was consistent with Hg accumulation measured in bivalves. The elevated Hg levels found in living bivalves collected from highly contaminated sites suggested that the sediment bound Hg was bioavailable. THg in surface soils, brown rice grain (Jasmine rice #105) and Neem flowers of terrestrial habitats were in the range of 16 to 180 microg kg(-1) dw, 190 to 300 microg kg(-1) dw, and 622 to 2150 microg kg(-1) dw, respectively. Elevated concentrations of mercury were found in Neem flowers

-groups. RESULTS: The total number of diagnoses of dermatosis was 280 with an average number of 3. 73/ per elderly person and 32 different types of dermatosis: were found. The prevalence of the dermatosis most often found was respectively: melanosis (53.3%, seborrheic keratosis (46.6%, onychomycosis (37.3%, nevus (33.3%, senile purpura (29.3%, xerosis (14.6%, scabies (12.0% and malignant neoplasm (1.3%. The distribution of dermatosis was 70% (CI95%: 59% to 81% higher in the female population than in the male. CONCLUSION: Notwithstanding the small number of cases, these data are compatible with the few reports available in literature. This study of prevalence defined the distribution of dermatosis in a fraction of the elderly population. However the aggregate data of subsequent casuistries may provide the more precise information whose relevance is undeniable in the orientation of individual and collective future health measures.

The goal of the present review is to collect information concerning membrane effects induced by lindane intoxication, a y isomer of hexachiorocyclohexane (gamma-HCH) that has been largely used as an insecticide and disinfectant in agriculture and entered also in the composition of some lotions, creams and shampoos used against parasites (lice and scabies). Absorbed through respiratory, digestive or transcutaneous pathways, lindane accumulates within lipid rich tissues. Lindane accumulation depends on the duration of the exposure and affects tissues in the following order: adipose tissues > brain > kidney > muscle > lungs > heart > liver > blood. Whatever the mode of lindane absorption, it accumulates in blood and is distributed throughout the body. It may affect human health by exerting systemic, immunologic, teratogenic, and/or cancerogenic effects. The symptoms of lindane intoxication are different according to the mode of intoxication, acute or chronic. The absorption of high doses of gamma-HCH is particularly toxic for the central nervous system and for the female and male reproduction apparatus in mammals where lindane is considered as an endocrine disruptor. Lindane is highly lipophilic and incorporates into biological membranes according to the following sequence: mitochondria > sarcoplasmic reticulum > myelin > brain microsomes > erythrocytes. Lindane exerts a stimulating action on synaptic transmission and inhibits the chloride current activated by gamma-amino butyric acid (GABA) of many muscular and nervous preparations by interacting with the receptors GABA-chloride channel complex. It seems to affect calcium homeostasis of many tissues. The similarity between lindane and inositol (1, 4, 5) phosphate (IP3) suggested that lindane releases Ca2+ from IP3-sensitive intracellular stores in macrophages and myometrial cells. Ca2+ release from reticulum endoplasmic, mitochondria and other Ca2+ stores has been reported in cat kidney cells. Lindane altered

Full Text Available A cross-sectional survey of 19 dairy sheep farms in Argentina was carried out with the purpose to know farm management, health practices, and occurrence and mortality of diseases. The survey comprised 40% of all sheep milking farms in Argentina. A questionnaire was conducted by way of personal interviews with sheep owners during farm visits. The proportions of farms reporting routine vaccination for clostridial diseases, contagious ecthyma, pneumonia and mineral and vitamin parenteral administration were 63%, 47.3%, 16.6% and 42.1% respectively. Regular treatment against lice was used in 37.5% of the farms, and 89.5% o the farmers treated against gastrointestinal nematodes (GIN. The mean number of GIN drenches per farm was 2.26±1.78 annually. In 68.4% of the milking flocks the California Mastitis Test was regularly done and 55.6% of the farmer managers had sampled their flocks once a year for Brucella ovis antibodies. During the pre-mating period respectively 68.4% and 50% of farmers clinically examined their rams and ewe for general health and teeth condition. The udders of ewes were frequently inspected at the start of each milking period. The most important parasite problems noticed were GIN (reported by 57.9% of farmers, lice (57.9% and scabies (10.5% and the most frequent infectious diseases were ecthyma (73.7%, pneumonia and other respiratory problems (57.9%, clinical mastitis (55.6%, clostridial diseases (36.9% and foot lameness (35.2%. Photosensitivity (47.4% and ruminal acidosis (42.1% were reported as other frequent toxic or metabolic disorders. Owners mentioned that the mean lifespan or milk productive time per ewe was 4.5±1.4 years. Perinatal lamb mortality was 8.5% and the total flock mortality rates, above the first 24 h of life was 6.9%. The high rates of lamb mortality during the pre-weaning (10.3% and post-weaning (5.9% periods indicate that this problem, as well as the most prevalent diseases, should be the subject of further

Boychuk Taras, Moysey Antoniy. Participation of Chernivtsi State Medical Institute in the liquidation of the skin and venereal diseases in Chernivtsi region during 1946-1949 periods Abstract. Monitoring carried out by authoritative international organizations in the health care sector shows a significant proliferation of the world's diseases such as syphilis, gonorrhea, trichomoniasis, chlamydia. Annually in the world are registered about 60 million cases of syphilis, 300 million cases of scabies, skin disease affects 30 to 70% of humanity. In recent years in Ukraine has increased the incidence of syphilis among children and teenagers. Worryingly, those 15% increases in the number of cases are children with early latent syphilis. Among teenage girls secondary recurrent syphilis appears three times more often than boys, what generally is a negative prognostic criterion for the health of future generations of the country. Enough high incidence of syphilis and other infections what are transmitted sexually, requiring immediate development and approval of the State intersectoral programs to combat spread of these infections. It will contribute to the preservation and strengthening of the nation's gene pool. This situation requires the accumulation and use of experience of combating infectious diseases. It was developed by Ukrainian scientists and practitioners. In this regard, an absolute value has the experience of Chernivtsi State Medical Institute (CHSMI stuff gained during the campaign to combat syphilis in 1946 in the Chernivtsi region. In that research period was developed the problem and were run special treatment methods of the
