MedWorm: Scabies

Michael Agus reports on his final days in Haiti

Thrive, Children's Hospital Boston — Wed, 17 Mar 2010 16:02:42 +0100

by Michael Agus, MD, director of Children’s Medicine Critical Care Program. Agus is currently in Port-au-Prince, Haiti, where he’s treating patients and sending us updates by email. Day 10 I wasn’t supposed to work the day today because I now have to start working nights since there is a few days’ gap in the night pediatric physician coverage. But after a good night’s sleep, and with two intubated patients in the pediatric tents with no other intensivist on site, I felt like I should go for morning rounds, set a plan for the day and then sleep on the hospital grounds to rest up for the night. At first glance, the tents seemed quiet. I, as well as the residents and nurses, wandered in and out over the next few hours and both ventilated patients were stable. I had hoped...

If simply the thought of bedbugs, scabies and head lice makes you feel a little itchy, imagine how those affected by these common infestations feel when they learn what has been creeping around them and causing symptoms such as intense itching, red bite marks or irritated scalps. Even less comforting is the fact that some parasitic infestations are on the rise, and can strike adults and children in unsuspecting places.

Biodegradation of 5-Nitroanthranilic Acid by Bradyrhizobium sp. Strain JS329.

Applied and Environmental Microbiology — Fri, 15 Jan 2010 00:00:00 +0100

Authors: Qu Y, Spain JC Biodegradation of synthetic compounds has been studied extensively, but the metabolic diversity required for catabolism of many natural compounds has not been addressed. 5-Nitroanthranilic acid (5NAA), produced in soil by Streptomyces scabies, is also the starting material for synthetic dyes and other nitroaromatic compounds. Bradyrhizobium JS329 was isolated from soil by selective enrichment with 5NAA. When grown on 5NAA the isolate released stoichiometric amounts of nitrite and half of the stoichiometric amounts of ammonia. Enzyme assays indicate that the initial step in 5NAA degradation is an unusual hydrolytic deamination to form 5-nitrosalicylic acid (5NSA). Cloning and heterologous expression revealed the genes that encode 5NAA deaminase (naaA) and 5NSA di...

A nurse-led response to unmet needs of homeless migrants in inner London.

British Journal of Nursing — Thu, 14 Jan 2010 00:00:00 +0100

Authors: Collinson S, Ward R The economic recession has left many undocumented migrants from the European Union accession states stranded and unemployed in the UK, without recourse to public funds. The TB team at Homerton University Hospital found a significant number of eastern Europeans squatting in derelict buildings in the London borough of Hackney. Because of the high rate of tuberculosis (TB) in Hackney, the team developed an outreach clinic to screen people for TB. During this screening initiative, which took place between August 2008 and March 2009, team members compiled a database of 98 eastern European citizens, and screened 62 for TB. Team members became aware during this time that, while eastern Europeans had significant health problems ranging from alcohol dependency to tr...

Crusted (Norwegian) scabies following systemic and topical corticosteroid therapy.

J Korean Med Sci — Fri, 01 Jan 2010 00:00:00 +0100

Authors: Binić I, Janković A, Jovanović D, Ljubenović M It is a case study of a 62-yr-old female with crusted (Norwegian) scabies, which appeared during her treatment with systemic and topical corticosteroid therapy, under the diagnosis of erythroderma. In the same time, the patient had been suffered from hypothyoidism, and her skin changes were misdiagnosed, because it was thought that they are associated with her endocrine disorder. Suddenly, beside the erythema, her skin became hyperkeratotic, with widespread scaling over the trunk and limbs, and crusted lesions appeared on her scalp and ears. The microscopic examination of the skin scales with potassium hydroxide demonstrated numerous scabies mites and eggs. Repeated topical treatments with lindan, benzoyl b...

What Causes Peeling Fingers and Toes?

PediatricEducation.org — Mon, 14 Dec 2009 00:32:42 +0100

Discussion Palmar and plantar hyperkeratosis is localized or diffuse thickening of the palmar and solar stratum corneum. It can occur in isolation or as part of a generalized disorder such as Sjögren-Larsson syndrome, Conradi’s syndrome, psoriasis, and hypohidrotic ectodermal dysplasia. Treatment includes agents to increase exfoliation such as lactic acid, salicylic acid or urea and soaking and mechanical exfoliation with a pumice stone or scalpel. These are used so tissue build up is decreased. Emollients need to be applied to help prevent fissuring from mechanical stress. Other possible treatments include topical psoralens with ultraviolet A light, topical retinoids or corticosteroids. Learning Point The differential diagnosis of desquamating digits includes: Localized or sem...

Skin Disorders, Including Pyoderma, Scabies, and Tinea Infections

Pediatric Clinics of North America — Tue, 01 Dec 2009 00:00:00 +0100

Pyoderma, scabies, and tinea are common childhood skin disorders too often considered to be merely of nuisance value. More than 111 million children are believed to have pyoderma, with many also co-infected with scabies, tinea, or both. These skin disorders cannot be differentiated by ethnicity or socioeconomic status but, in high-prevalence areas, poverty and overcrowded living conditions are important underlying social determinants. Each is transmitted primarily through direct skin-to-skin contact. For many Indigenous children, these skin conditions are part of everyday life. Although rarely directly resulting in hospitalization or death, there is a high and largely unmet demand for effective management at the primary health-care level, particularly for pyoderma and scabies. Despite part...

Characterization of a Serine Protease Homologous to House Dust Mite Group 3 Allergens from the Scabies Mite Sarcoptes scabiei [Enzyme Catalysis and Regulation]

Journal of Biological Chemistry — Fri, 27 Nov 2009 17:05:45 +0100

The scabies mite, Sarcoptes scabiei var. hominis, infests human skin, causing allergic reactions and facilitating bacterial infection by Streptococcus sp., with serious consequences such as rheumatic fever and rheumatic heart disease. To identify a possible drug target or vaccine candidate protein, we searched for homologues of the group 3 allergen of house dust mites, which we subsequently identified in a cDNA library. The native protein, designated Sar s 3, was shown to be present in the mite gut and excreted in fecal pellets into mite burrows within the upper epidermis. The substrate specificity of proteolytically active recombinant rSar s 3 was elucidated by screening a bacteriophage library. A preference for substrates containing a RS(G/A) sequence at the P1-P2' positions was revealed...

Scabies and pyodermas – diagnosis and treatment

Dermatologic Therapy — Wed, 04 Nov 2009 00:00:00 +0100

Scabies and pyodermas are two of the commonest skin infections in tropical settings. They affect large numbers of people, particularly children, and account for a large burden of disease for peripheral health care teams. Despite this there have been significant advances in our knowledge of these diseases, their impact and their management. However there is a need to evaluate these developments in this specific setting, tropical health and in the context of communities with limited resources. This section will describe these advances and the challenges that remain. (Source: Dermatologic Therapy)

This study was conducted to assess the prevalence of scabies and control measures in Japanese hospitals. A questionnaire on scabies epidemiology (e.g. number of patients and onsets of outbreak) and preventive measures were sent to psychiatric hospitals and long-term care hospitals nationwide (n = 1795) in January 2005. Seven hundred and forty-one hospitals responded (41.3%). Three hundred and thirty-three (44.9%) respondent hospitals had one or more scabies cases in 2004. Among 159 hospitals that had experienced scabies outbreak, only 32 of them reported cases of crusted scabies. Multivariate regression analysis showed that hospitals had a greater number of beds, and that acute- and long-term care wards were more likely to experience scabies onsets.

Modulation of human dermal microvascular endothelial cells by Sarcoptes scabiei in combination with proinflammatory cytokines, histamine, and lipid-derived biologic mediators.

Cytokine — Tue, 09 Jun 2009 23:00:00 +0100

This study was undertaken to determine if the response of HMVEC-D to scabies is altered in the presence of various proinflammatory cytokines (tumor necrosis factor alpha and interleukins 1alpha, 1beta and 6), histamine, and lipid-derived mediators (prostaglandins D2 and E2, leukotriene B4, platelet activation factor) that likely occur in scabietic lesions in vivo. Scabies extract down-regulated the TNFalpha-induced expression of VCAM-1 by HMVEC-D and this down-regulation still occurred in the presence of the other proinflammatory cytokines, histamine or the lipid-derived mediators. Scabies inhibited the IL-1alpha and IL-1beta-induced secretion of IL-6, while a combination of scabies and histamine or LTB4 reduced the TNFalpha-induced secretion of IL-6.

A practical approach to common skin problems in returning travellers

Travel Medicine and Infectious Disease — Mon, 13 Apr 2009 04:00:00 +0100

Summary: Skin diseases are the third most common cause of morbidity in returning travellers and may affect 8% of travellers during travel. Classic tropical diseases account for one quarter and the remainder are cosmopolitan diseases. The majority are of infectious origin, and of these bacterial infections are the most common and lead to the most hospitalisations. The ten most frequently encountered diagnoses comprise four classical tropical infections (cutaneous larva migrans, myiasis, tungiasis and cutaneous leishmaniasis) and six nontropical diseases (bacterial skin infections, arthropod bites, allergic reactions, scabies, animal bites and superficial fungal infections). Other notable skin problems include swimmer's itch, dengue fever presenting with a rash and rickettsial infections pre...

Pruritus measurement and treatment.

Clinical And Experimental Dermatology — Wed, 01 Apr 2009 04:00:00 +0100

Authors: Langner MD, Maibach HI Pruritus measurement is problematic, because of its subjective nature and poor localization. Ratio scales enhance the usefulness of the visual analogue scale (VAS) by reducing variation; other scales such as the generalized labelled magnitude scale may also be useful. Pruritus neuroanatomy includes peripheral receptors, peripheral and central nerves, ascending and descending spinal pathways, and several brain regions. Pruritus receptors include Merkel discs and free nerve endings, and itch receptors have fast or slow adaptation. In this review, we discuss the pathophysiology of pruritus in atopic dermatitis, psoriasis and scabies. Pruritus treatment is reviewed for topical agents and antihistamines. Future research directions are suggested. PMID: 193...

Preliminary study of effectiveness of aloe vera in scabies treatment

Phytotherapy Research — Mon, 09 Mar 2009 04:00:00 +0100

In an open, non-comparative study carried out between August and December 2002 at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria, 5 patients with scabies were successfully treated with crude gel of Aloe vera; thereafter the efficacy of the extract was compared with that of benzoate lotion among 30 patients. Sixteen patients were treated with Aloe vera and 14 patients had benzyl benzoate lotion. Itching was still present in 3 patients in the benzyl benzoate group and in 2 patients in the Aloe vera group after 2 courses of treatment. The scabietic lesions virtually disappeared in all of them. None of these patients had any noticeable side effects. It is concluded that Aloe vera gel is as effective as benzyl benzoate in the treatment of scabies. Copyright © 2009 ...

Validation of an Integrated Management of Childhood Illness algorithm for managing common skin conditions in Fiji.

Bulletin of the World Health Organization — Sun, 01 Mar 2009 00:00:00 +0100

CONCLUSION: The IMCI skin algorithm is a robust tool that should be incorporated into the IMCI after some modifications relating to scabies and impetigo. Its use by primary health-care workers will reduce the burden of skin diseases in children in Fiji through improved case identification and management. The algorithm should be considered in other countries where skin diseases in children are a priority, particularly in the Pacific region.

Epidermal parasitic skin diseases: a neglected category of poverty-associated plagues.

Bulletin of the World Health Organization — Sun, 01 Feb 2009 05:00:00 +0100

Authors: Feldmeier H, Heukelbach J Epidermal parasitic skin diseases (EPSD) are a heterogeneous category of infectious diseases in which parasite-host interactions are confined to the upper layer of the skin. The six major EPSD are scabies, pediculosis (capitis, corporis and pubis), tungiasis and hookworm-related cutaneous larva migrans. We summarize the current knowledge on EPSD and show that these diseases are widespread, polyparasitism is common, and significant primary and secondary morbidity occurs. We show that poverty favours the presence of animal reservoirs, ensures ongoing transmission, facilitates atypical methods of spreading infectious agents and increases the chances of exposure. This results in an extraordinarily high prevalence and intensity of infestation of EPSD in re...

'Wake sign': an important clue for the diagnosis of scabies.

Clinical And Experimental Dermatology — Tue, 02 Dec 2008 05:00:00 +0100

Authors: Yoshizumi J, Harada T Summary Japan is currently experiencing many outbreaks of scabies, occurring mainly in long-term care facilities. Scabies burrows, the only pathognomonic lesion for scabies, often occur on the creases of the palms, and are followed by a pattern of scale reminiscent of the 'wake' left on the surface of water by a moving bird or a ship (wake sign).(1-4) The wake sign is useful because (i) it is specific for scabies, (ii) it is sufficiently large to be found by the naked eye and (iii) it points towards the location of the mite and its products. Examination of patients' palms to look for this sign is a simple and efficient way to make a diagnosis of scabies throughout the course of an infestation.

Interactions and biocontrol of pathogenic Streptomyces strains co-occurring in potato scab lesions

Journal of Applied Microbiology — Mon, 01 Dec 2008 05:00:00 +0100

Conclusions: Streptomyces turgidiscabies shows antagonism against S. scabies that occurs in the same scab lesions and shares the ecological niche in the field. Biocontrol of S. turgidiscabies is possible with nonpathogenic Streptomyces strains but interactions may be complicated.Significance and Impact of the Study: Streptomyces turgidiscabies may have potential to displace S. scabies under the Scandinavian potato growing conditions. Biological control of the severe potato scab pathogen, S. turgidiscabies, is demonstrated for the first time. The results can be applied to enhance control of common scab.

[Report on erythroderma and scabies infection in connection with two cases of scabies norvegica.]

Orvosi Hetilap — Sat, 15 Nov 2008 12:57:59 +0100

Authors: Jenei M, Veres I, Schmidt E, Varga I, Remenyik E Erythroderma is an inflammation of almost the whole surface of the skin, characterized by erythema, skin infiltration and desquamation. Despite the etiological factors, the generalized inflammation of a large body surface can lead to a life-threatening condition in itself. Parasite infection lies rarely in the background of erythroderma. The Sarcoptes scabiei var. hominis belonging to the mite family is the cause of scabies disease. While the prevalence of "classic" scabies is high world-wide, the more severe and more dangerous form - scabies norvegica - is only seldomly observed. Diagnosis and treatment is highly important from an epidemiological aspect. The authors discuss the differential diagnostic problems and epidemiologic...

Genetic diversity of Streptomyces spp. causing common scab of potato in eastern Canada.

Systematic and Applied Microbiology — Wed, 22 Oct 2008 04:00:00 +0100

In this study, the genetic diversity of Streptomyces spp. causing common scab of potato in eastern Canada was for the first time investigated. Forty-one Streptomyces spp. isolates were retrieved from necrotic lesions of potato tubers harvested from different regions of the Canadian provinces New-Brunswick, Nova Scotia and Prince-Edward-Island. Most isolates were closely related to known pathogenic S. scabies strains on the basis of partial 16S ribosomal (r) RNA and rpoB gene sequence analyses. Two isolates were identified as pathogenic species of Streptomyces acidiscabies. To our knowledge, this species has never been previously isolated in these areas. Genome fingerprinting studies using repetitive elements (rep) polymerase chain reactions (PCR) revealed 10 distinct genetic groups in east...

Synthesis and uptake of the compatible solutes ectoine and 5-hydroxyectoine by Streptomyces coelicolor A3(2) in response to salt and heat stress.

Applied and Environmental Microbiology — Fri, 10 Oct 2008 04:00:00 +0100

Authors: Bursy J, Kuhlmann AU, Pittelkow M, Hartmann H, Jebbar M, Pierik AJ, Bremer E Streptomyces coelicolor A3(2) synthesizes ectoine and 5-hydroxyectoine upon the imposition of either salt (0.5 M NaCl) or heat stress (39 degrees C). The cells produced the highest cellular levels of these compatible solutes when both stress conditions were simultaneously imposed. Protection against either severe salt (1.2 M NaCl) or heat stress (39 degrees C) or a combination of both environmental cues could be accomplished by adding low concentrations (1 mM) of either ectoine or 5-hydroxyectoine to S. coelicolor A3(2) cultures. The best salt and heat stress protection was observed when a mixture of ectoine and 5-hydroxyectoine (0.5 mM each) were provided to the growth medium. Transport assays with r...

Evaluation of wound healing activity of Lantana camara L. - a Preclinical study

Phytotherapy Research — Thu, 09 Oct 2008 04:00:00 +0100

The objective of our study was to investigate excision wound healing activity of the leaf extract of L. camara in rats. The animals were divided into two groups of 12 each in both the models. The test group animals were treated with the aqueous extract of L. camara (100 mg/kg/day) topically and the control group animals were left untreated. Wound healing efficacy was measured by determining the morphological and biochemical parameters. Wound healing time, wound contraction and synthesis of collagen were monitored periodically. Antimicrobial activities of the extract against the microorganisms were also assessed. Treatment of the wounds with extract enhanced significantly the rate of wound contraction (98%), synthesis of collagen and decreased mean wound healing time. These studies demonstr...

Thaxtomin biosynthesis: the path to plant pathogenicity in the genus Streptomyces.

Antonie van Leeuwenhoek — Sun, 01 Jun 2008 04:00:00 +0100

Authors: Loria R, Bignell DR, Moll S, Huguet-Tapia JC, Joshi MV, Johnson EG, Seipke RF, Gibson DM Streptomyces species are best known for their ability to produce a wide array of medically and agriculturally important secondary metabolites. However, there is a growing number of species which, like Streptomyces scabies, can function as plant pathogens and cause scab disease on economically important crops such as potato. All of these species produce the phytotoxin thaxtomin, a nitrated dipeptide which inhibits cellulose synthesis in expanding plant tissue. The biosynthesis of thaxtomin involves conserved non-ribosomal peptide synthetases, P450 monooxygenases, and a nitric oxide synthase, the latter being required for nitration of the toxin. This nitric oxide synthase is also responsible...

Against conservation of specific epithets formed wrongly as nominative nouns in apposition.

Disease burden and health-care clinic attendances for young children in remote aboriginal communities of northern Australia.

Bulletin of the World Health Organization — Tue, 01 Apr 2008 04:00:00 +0100

CONCLUSION: These Aboriginal children average about two visits per month to PHC centres during their first year of life. This high rate is testament to the disease burden, the willingness of Aboriginal people to use health services and the high workload experienced by these health services. Scabies and skin sores remain significant health problems, with this study describing a previously undocumented burden of these conditions commencing within the first few months of life. Appropriate prevention and treatment strategies should encompass early infancy to reduce the high burden of infectious diseases in this population.

life'> Life after Lindane in California Water Concentrations, Poison Control Calls Drop Following Ban Lindane, a persistent, highly toxic, and bioaccumulative organochlorine insecticide, was used in agriculture and as a topical treatment for human head lice and scabies beginning in the 1940s. As its toxicity became better known, manufacture and use declined in the United States; in 2002, California banned the pharmaceutical use of lindane altogether. According to a new study, that ban appears to have resulted in steep drops in concentrations of lindane in Southern California's wastewater and a dramatic reduction in calls to the California Poison Control System [EHP 116:297 302; Humphreys et al.]. The most common adverse effects of lindane exposure in humans include seizures, dizziness, and headaches. High levels of exposure can be fatal. Although the U.S. Environmental Protection Agency has canceled all registrations for lindane-containing compounds in agriculture, the chemical is still available by prescription as a second-line treatment for head lice in states other than California. Its continued pharmaceutical use raises concerns about its potential presence in wastewater effluent and drinking water. The research team, part of the University of California, San Francisco, Pediatric Environmental Health Specialty Unit, examined historical lindane concentrations in several Southern California water pollution control plants and compared them before and after the ban. To assess the ban's impact on human exposures, they analyzed lindane-related calls to California's poison control hotline between 1998 and 2006. They searched the Medi-Cal fee-for-service pharmacy-paid claims database and obtained national data from Verispan, a commercial health industry data tracker, to determine the number of lindane prescriptions issued. The team also conducted a random survey of pediatricians to ascertain both their awareness of the ban and their current treatment preferences for scabies and head lice. In Los Angeles County, the average wastewater concentration of lindane in 1999 was 36 ppt. By 2006, concentrations had dropped to almost undetectable levels throughout California. In 1998, 135 per 100,000 calls to the Poison Control System concerned lindane; by 2006 such calls had declined to 2 per 100,000. Similarly, lindane prescriptions fell from 114,000 in 1997 to 34 in 2002. Medical providers reported few problems using alternative treatments such as pyrethrins. The study authors are encouraged by their findings but note that lindane is still used in many countries, mostly in the developing world, and that every ton of lindane manufactured produces about 9 tons of toxic waste. Although the U.S. Food and Drug Administration has not banned pharmaceutical lindane in the United States, the pesticide is currently under review for inclusion in the Stockholm Convention on Persistent Organic Pollutants, which could eventually lead to a worldwide ban.

American Family Physician — Thu, 01 Nov 2007 04:00:00 +0100

Authors: Rabinowitz PM, Gordon Z, Odofin L Human contact with cats, dogs, and other pets results in several million infections each year in the United States, ranging from self-limited skin conditions to life-threatening systemic illnesses. Toxoplasmosis is one of the most common pet-related parasitic infections. Although toxoplasmosis is usually asymptomatic or mild, it may cause serious congenital infection if a woman is exposed during pregnancy, particularly in the first trimester. Common pet-borne fungal infections include tinea corporis/capitis (ringworm); campylobacteriosis and salmonellosis are among the most common bacterial infections associated with pet ownership. Less commonly, pets can transmit arthropod-borne and viral illnesses (e.g., scabies, rabies). Infection in a pet ...

Problems in diagnosing scabies, a global disease in human and animal populations.

Clinical Microbiology Reviews — Sun, 01 Apr 2007 04:00:00 +0100

Authors: Walton SF, Currie BJ Scabies is a worldwide disease and a major public health problem in many developing countries, related primarily to poverty and overcrowding. In remote Aboriginal communities in northern Australia, prevalences of up to 50% among children have been described, despite the availability of effective chemotherapy. Sarcoptic mange is also an important veterinary disease engendering significant morbidity and mortality in wild, domestic, and farmed animals. Scabies is caused by the ectoparasitic mite Sarcoptes scabiei burrowing into the host epidermis. Clinical symptoms include intensely itchy lesions that often are a precursor to secondary bacterial pyoderma, septicemia, and, in humans, poststreptococcal glomerulonephritis. Although diagnosed scabies cases can be...

What Treatments are Recommended for Head Lice?

PediatricEducation.org — Sun, 18 Mar 2007 08:54:04 +0100

Discussion Pediculosis capitis or head lice is a common human infestation. Patients often are asymptomatic but itching is a common symptoms. Adult lice may be seen and nits (eggs) are found on the hair shafts. Lice lay eggs within 3-4 mm of the scalp and so the time since infestation can be approximated because hair grows at a rate of ~1 cm/month. Parents often worry that infestation is a sign of poor hygiene but all socioeconomic groups are affected. Lice do not spread disease and therefore are not a health hazard. Transmission is by direct contact with the hair of infested persons or objects such as hats, combs and brushes. The incubation period is 10-14 days but can be lengthened in cold climates and shortened in warm climates. Adult lice can produce eggs after 2 weeks. Learning P...
