RESUMO

Se estima que, en el 2018, 5 millones de personas vivían en zonas de la Región de las Américas en las que el tracoma representa un problema de salud pública, en particular en Brasil, Colombia, Guatemala y Perú. Como parte de las actividades para determinar la situación del tracoma, la Organización Panamericana de la Salud (OPS) ha impulsado la búsqueda de grupos afectados por la enfermedad en otros países de la Región, principalmente en poblaciones que, como las de la Amazonia, se encuentran en situación de vulnerabilidad. En octubre del 2019 se celebró en Ciudad de Panamá (Panamá) una reunión dirigida a establecer una hoja de ruta que abordase el tracoma de manera integrada con otras enfermedades infecciosas desatendidas (como la geohelmintiasis, la filariasis linfática, las ectoparasitosis, la lepra, la enfermedad de Chagas y el pian) y otras enfermedades oculares que causan ceguera (catarata madura y pterigión avanzado) para poblaciones en zonas de difícil acceso en la Amazonia.Este informe —disponible en español, inglés y portugués— presenta las recomendaciones de los participantes en la reunión en dos esferas de trabajo: 1) el mapeo integrado de las enfermedades y los factores de riesgo asociados y 2) las acciones integradas para el control y la eliminación de las enfermedades.

RESUMO

Scabies is an ectoparasitosis caused by Sarcoptes scabiei var. hominis, characterized clinically by pruritic lesions in typical locations; the crusted form is a rare manifestation. The diagnosis is usually established based on the clinical picture, but dermoscopy can be an important complementary method, as it allows the observation of a brownish triangular structure with a hang-glider appearance. A case of crusted scabies is reported; the magnification of the images obtained by digital dermoscopy allowed the demonstration of a structure usually observed only with videodermoscopy.

RESUMO

En el 2016, con ocasión del 55.° Consejo Directivo de la Organización Panamericana de la Salud (OPS), se aprobó el Plan de acción para la eliminación de las enfermedades infecciosas desatendidas y las medidas posteriores a la eliminación 2016-2022 (documento CD55/15), uno de cuyos objetivos era evaluar la situación epidemiológica regional de otras enfermedades infecciosas desatendidas como las ectoparasitosis. En este marco, y con la necesidad de identificar las acciones para avanzar hacia el objetivo establecido, se celebró la reunión sobre Enfermedades Ectoparasitarias en la Región de las Américas: Desarrollo de una hoja de ruta para establecer la situación epidemiológica e identificar acciones para reducir su impacto, en Belo Horizonte (Brasil) el 29 y 30 de julio del 2019. Los participantes de la reunión (anexo) recomendaron la puesta en marcha de acciones en tres componentes principales: mapeo y vigilancia epidemiológica, intervenciones integradas, e investigación operativa y de aplicación. Con base en la experiencia presentada por los delegados de Brasil y Colombia, así como en los resultados de la revisión de los documentos existentes sobre las características epidemiológicas de las ectoparasitosis en la Región de las Américas desarrollada por el Programa Regional de Enfermedades Infecciosas Desatendidas de la OPS1, se concluyó que se incluirán en esta iniciativa la tungiasis (causada por Tunga penetrans), la escabiosis (causada por Sarcoptes scabiei) y la pediculosis capilar (causada por Pediculus humanus var. capitis); además, se incluirán la miasis (causada por Dermatobia hominis y Cochliomyia hominivorax, entre más de 30 especies de moscas) y la larva migratoria cutánea causada por uncinarias (Ancylostoma caninum, Ancylostoma brasiliense y Ancylostoma tubiformae). A continuación, se presenta la hoja de ruta propuesta con los componentes y acciones recomendadas.

RESUMO

Autoimmune and autoinflammatory diseases are associated with severe morbidity, and represent an impactful health and economic burden worldwide. The treatment of these diseases can include a course with detrimental side effects. Immunosuppression increases the risk of opportunistic infections, but in some cases, the abrupt discontinuation of these medications can result in immune reconstitution inflammatory syndrome. Special attention must be directed to endemic tropical infections, such as leishmaniasis, Chagas disease, malaria, arbovirosis, yellow fever, leprosy, paracoccidioidomycosis, disseminated strongyloidiasis, and ectoparasitosis. These endemic diseases of developing countries can be considered as possible emerging diseases in developed regions partially because of environmental factors and migration. In the present article, we aim to review the evidence-based aspects of the most important opportunistic tropical infections in immunosuppressed patients. We also aim to review the important aspects of vaccination, chemical prophylaxis, and treatment for these infections in people with medication-induced immunosuppression.

RESUMO

Pediculosis capitis is the most frequent ectoparasitosis around the world. The infestation is caused by Pediculus humanus capitis (head louse), which affects hair, scalp, and skin. It rarely presents with more symptoms and in the majority of the cases, it shows a benign course if treated properly. We present the case of a nursery school girl with head lice infestation for 18 months. She did not improve after the shampoo treatment. This case was associated with furunculosis, skin lesions, multiple adenopathies, and anemia. Initially, the presence of boils, alopecia, and lymphadenopathy was evident. The persistence of pediculosis capitis and intense scratching induced changes on skin integrity, facilitating opportunistic bacterial superinfection that led to impetiginization, furunculosis, excoriations, hematic scabs, anemia, alopecia, and lymphadenopathies. Pediculosis capitis affected the patient triggering psychological, economic, social, and other health problems. The patient presented uncommon symptoms (furunculosis, anemia, fever, alopecia, and adenopathies) resulting from the persistence of risk factors and the absence of head inspection and mechanical removal of insects. The education about the risk factors, as well as sanitary controls, are essential to contain the infestation.

RESUMO

RESUMEN Latungiasisesuna ectoparasitosistransitoria en el ser humano, que se produce a causa de la penetración en la piel de la hembra grávida de la "pulga de arena", Tunga penetrans. También es conocida como "nigua", "bichodopé", "sandflea",entre otras denominaciones. Es una enfermedad endémica en áreas rurales y playas de Centro y Sudamérica, Caribe y África Subsahariana. En Argentina se la encuentra en zonas del Noreste y Mesopotamia. Debido al incremento de los destinos vacacionales a dichas regiones tropicales, comenzaron a observarse casos de tungiasis fuera de las áreas endémicas (casos importados). Comunicamos el caso de una niña argentina, que vacacionó en las playas caribeñas y adquirió la infestación por Tunga penetrans, la cual evolucionó de manera llamativa, manifestando un fenómeno isotópico.


SUMMARY Tungiasis is a transitory ectoparasitosis caused by penetration into the skin of the female flea Tungapenetrans, also known as "nigua", "bichodo pé", or "sand flea". It's an endemic disease that can be found at rural zones, Caribbean beaches and Sub-Saharan Africa. In Argentina, it's distributed in the northeastand Mesopotamia. Because of the increasement of holiday destinations, in these tropical regions, cases of tungiasis were reported outside the endemic areas. People who went to those zones, carried the disease to their birthplaces (imported Infestations). We report the case of a little Argentinian girl who went to a Caribbean beach and acquired the infestation by tungapenetrans, which made its develop in a striking way; showing an isotopic phenomenon.

RESUMO

Resumen La pediculosis capitis es la ectoparasitosis más frecuente a nivel mundial. La infestación es causada por Pediculus humanus capitis (piojo de la cabeza) y afecta el cabello, el cuero cabelludo y la piel. Rara vez se manifiesta con otro tipo de sintomatología y, por lo general, su curso es benigno si se trata adecuadamente. Se presenta el caso de una menor con pediculosis capitis de 18 meses de evolución, asociada con forúnculos, lesiones cutáneas, múltiples adenopatías y anemia, que no mejoró tras la aplicación del champú. Inicialmente, llamó la atención la presencia de forúnculos, alopecia y adenopatías. La persistencia de la pediculosis capitis y el rascado intenso alteraron la integridad de la epidermis y facilitaron las infecciones secundarias por bacterias patógenas y oportunistas que produjeron impétigo, forunculosis, excoriaciones, costras hemáticas, anemia, alopecia y linfadenopatías. La pediculosis capitis afectó notoriamente a la paciente al causarle problemas psicológicos y de salud, agudizados por su condición económica y social. La paciente presentó manifestaciones clínicas poco frecuentes (forunculosis, anemia, fiebre, alopecia y adenopatías), lo cual se vio facilitado por la persistencia de los factores de riesgo y el hecho de que no se le inspeccionaba la cabeza ni se removían los insectos. La educación sobre los factores de riesgo y el control sanitario es indispensable para controlar la infestación.

RESUMO

Scabies is a frequent ectoparasitosis the prevalence of which also seems to increase in older patients. Correct and timely diagnosis of scabies in older age is hampered by atypical clinical manifestations, the potential lack of pruritus and a variety of differential diagnoses. Scabies crustosa, a highly contagious subtype due to the presence of innumerable mites, is of particular importance. It predominantly occurs in immunosuppressed patients as well as in mentally or physically disabled persons and is the most important source of scabies outbreaks in residential and nursing homes. This article reviews the diagnosis and treatment of scabies and the strategies for managing outbreaks with special reference to older patients.

RESUMO

INTRODUCTION: In the 1970s and 1980s, the occurrence of bedbugs (Cimex lectularius Linnaeus, 1758) was noticed only sporadically in accommodation facilities in Slovakia. Under regular monitoring, it was possible to even eradicate its occurrence in the 1980s. Today, the problem is once again a major global health issue. OBJECTIVE: The aim of the study was to point out the occurrence of cimicosis in the case of atypical urticaria in patients referred to parasitological examination by inpatient and outpatient physicians. MATERIAL AND METHODS: During the period 2006-2015, 102 patients with suspected ectoparasitosis were examined in the Diagnostic Laboratory of Human Parasitology at the Faculty of Medicine of Comenius University in Bratislava. Specialists and general practitioners referred the patients with itching red efflorescences. Parasitological examination and entomologic analysis of insects confirmed in many of them the presence of skin ectoparasitosis caused by Cimex lectularius, and in one case Oeciacus hirundinis. RESULTS: A total number of 102 parasitologically patients were examined - 62 adults and 40 children. Among the 62 adults, there were 57 patients positive for cimicosis. In 5 patients cimicosis was not confirmed, in one of them (Sarcoptes scabiei Linnaeus, 1758) was detected. Among the 40 children, there were 34 positive for cimicosis. One female child was diagnosed with lesions caused by Sarcoptes scabiei.. CONCLUSIONS: The bed bug should again be subjected to the reporting service to public health authorities, and thus recording the monitoring of its incidence and spread in the population.

RESUMO

BACKGROUND: Tungiasis is a relatively frequent ectoparasitosis in low-income settings, yet its morbidity and social impact are still not well understood due to the scarcity of information. In Rwanda, data on the magnitude and conditions leading to the tungiasis is rare. This study sought to determine the prevalence and factors associated with tungiasis among primary school children in Rwandan setting. METHOD: A descriptive cross-sectional study utilising systematic random sampling method was adopted to select 384 children from three primary schools. From July to October 2018, data were collected on socio-demographic characteristics of children, parents, and households. Logistic regression was applied to analyse socio-demographic factors associated with tungiasis with a level of significance set at P-value< 0.05. RESULTS: Prevalence of tungiasis among three primary schools was 23%. Factors associated with tungiasis included walking barefoot (AOR: 78.41; 95% CI: 17.91-343.10), irregular wearing of shoes (AOR: 24.73; 95% CI: 6.27-97.41), having dirty feet (AOR: 12.69; 95% CI: 4.93-32.64), wearing dirty clothes (AOR: 12.69; 95% CI: 4.18-38.50), and living in a house with earthen plastered floor (AOR: 28.79; 95% CI: 7.11-116.57). Children infected with tungiasis attended class less frequently (AOR: 19.16, 95%CI: 7.20-50.97) and scored lower (AOR: 110.85, 95%CI: 43.08-285.20) than those non-infected. The low school attendance and poor performance could be partly explained by difficulty of walking, lack of concentration during school activities, and isolation or discrimination from classmates. CONCLUSION: Tungiasis was a public health challenge among school going children in a rural Rwandan setting. This study revealed that children affected with tungiasis had poor hygiene, inadequate housing environments and consequently poor school attendance and performance. Improving socio-economic conditions of households with special emphasis on hygiene of family members and housing conditions, would contribute to preventing tungiasis.

RESUMO

The introduction of invasive species is one of the greatest threats currently faced by natural ecosystems, causing ecological imbalances between native populations and transmission of a variety of diseases. We reported the interaction between two exotic species given by the parasitic infestation of the copepod Lernaea cyprinacea in the early stages of the development of the American bullfrog Lithobates catesbeianus in the central area of Argentina. In this paper we analysed the leukocyte profile of parasitized and non-parasitized tadpoles of L. catesbeianus with L. cyprinacea and their body condition (BC) as biomarkers of the health status of organisms. A total of 27 tadpoles of L. catesbeianus were analysed (12 non-parasitized and 15 parasitized). The lower BC recorded in parasitized organisms show a lower health status in these tadpoles, which could be affecting the metamorphosis and therefore impact at the population level. Leukocyte response of L. catesbeianus tadpoles to the parasitism of L. cyprinacea was found. Mature and immature lymphocyte frequencies and hematocrit were higher in parasitized compared to non-parasitized tadpoles, which is a typical response to the presence of parasites. However, eosinophils and monocytes were recorded at high frequencies in not parasitized tadpoles, which could be due to the important role played by these leucocytes in the metamorphosis of frogs. The results of this study constitute a first antecedent on leukocyte profile in aquatic stages of anurans during an ectoparasitosis and its possible implications for environmental health. The parasitism of L. cyprinacea influences the biology of the American bullfrog at both the individual and population levels. Parasitized individuals are not killed directly by the parasite, but they can create conditions for secondary infections, growth retardation, behavioral changes and, ultimately, reduce populations.

RESUMO

Dermanyssus gallinae is a haematophagous ectoparasite primarily known as a pest of domestic and wild birds. It occasionally feeds on a range of mammals, and, more importantly, is of growing concern in human medicine. This review highlights mite attacks on people working with poultry, and updates the increasing incidence of dermanyssosis in urban environments in Europe. Although several cases of dermanyssosis have been documented, there are a number of reasons why diagnosis of D. gallinae infestations in humans is likely to be underestimated. Firstly, medical specialists are not well aware of D. gallinae infestations in humans. There is also a lack of collaboration with specialists from other disciplines. The problem is compounded by misdiagnoses and by the lack of diagnostic tools. We review the literature on human dermanyssosis cases in Europe, and also provide information on the epidemiology, clinical, histo-pathological and immunological aspects of dermanyssosis. We stress the need for improved recognition of this challenging infestation in humans, and provide straightforward recommendations for health practitioners, starting with collection of the correct anamnestic information and including appropriate management methods for case recognition and resolution. Finally, we indicate the most urgent areas to be addressed by future research. RESEARCH HIGHLIGHTS Dermanyssus gallinae is of growing concern in human medicine. Most physicians are not well aware of dermanyssosis in humans. Bio-epidemiological and clinical aspects of this ectoparasitosis are highlighted. Practical key actions for diagnosis and correct management of infestation in humans are provided.

RESUMO

Cutaneous larva migrans (CLM; also called creeping eruption) is a cutaneous ectoparasitosis commonly observed in tropical countries. It is characterized by an erythematous, pruritic, and raised lesion with linear or serpiginous distribution, typically localized at the lower extremities. Oral ivermectin represents the most recommended current treatment, with important adverse effects associated. We report the clinical case of a 52-year old with CLM, successfully treated with topical ivermectin.

RESUMO

Pediculosis capitis is a public health problem not only in Brazil, but also in many countries worldwide. Children are the most likely population group to be infested. The purpose of this study was to verify the prevalence of head lice in children seen at the public hospital in Uberlândia, Minas Gerais State, and factors associated with ectoparasitosis in this group. In addition, data about the transmission, prevention and control were obtained from the children's parents or guardians. The scalp and hair of every child aged 2 to 12, attended to at the hospital pediatric outpatient clinic from 2015 to 2017, were examined. Questionnaires and characterization sheets were also used to obtain and record the information. The overall prevalence rate observed was 2.8%. The highest prevalence rates were observed in girls with medium length hair. Children presented a relatively low prevalence of head lice in the parasitological examinations. However, the answers to the questionnaires indicated that this ectoparasitosis is common in this population group. All the children examined were of school age, and their parents or guardians indicated the school environment as the main source of infestations. The responses to the questionnaires also highlighted evidence of negligence on the part of guardians of positive children regarding the occurrence of this ectoparasitosis. The information obtained indicates that authorities should design/improve their plans of action regarding guidelines for parents or guardians for adequate prevention and control of this ectoparasitosis

RESUMO

PURPOSE: In 2016, the number of refugees worldwide reached 65.6 million. So far, only limited data are available on the health status of refugees and asylum seekers (RAs). Especially, notifiable infectious diseases (NIDs) carry the risk of outbreaks in communal accommodations hosting RAs. METHODS: We conducted a monocentric retrolective cross-sectional study including 15,137 RAs treated in a special health care unit for RAs located in the major reception center in Munich from November 2014 to October 2016. Altogether 811 RAs with NIDs according to sections 6 and 7 of the German Infection Protection Act or with other infections relevant in the setting of a communal accommodation (RIDs) could be identified. RESULTS: The gender and age distribution was generally comparable to that of refugees in Germany. However, patients from East Africa and Nigeria were significantly overrepresented. NIDs/RIDs were dominated by cases of tuberculosis, hepatitis B, and vaccine-preventable and parasitic diseases. Significant risk factors included country of origin (COI) and age for hepatitis B, age for hepatitis C, gender and age for HIV, and COI, gender and age for tuberculosis and ectoparasitosis. Calculated prevalences of hepatitis B, hepatitis C, and HIV were mostly below those of the COI. Incidences of tuberculosis were mostly strongly elevated. CONCLUSIONS: COI, gender, and age have an impact on the occurrence of NIDs/RIDs. Early vaccinations and improved hygiene could be effective in preventing NIDs/RIDs in communal accommodations. Screening, prompt therapy, and infection protection measures are necessary to prevent the transmission of diseases.

RESUMO

Trombiculiasis is a common but underreported ectoparasitosis characterized by an infestation of the skin by the larval stage of various species of mites belonging to the phylum Arthropoda, class Arachnida, subclass Acarina. Clinical manifestations consist of pruritic erythematous and urticarial macules and papules located on covered thin and glabrous skin. In recent studies Neotrombicula autumnalis larvae have been described as the possible vectors of pathogens such as Borrelia burgdorferi and Anaplasma phagocytophilum. Few reports of trombiculosis have been collected in the medical literature to date. We report a typical case of trombiculosis induced by trombiculid larvae of N. autumnalis, which are habitual parasites of various endo- and ectothermic vertebrates.

RESUMO

Proposed at the beginning of the twentieth century to explain the origin of eukaryotic organelles from prokaryotes, endosymbiosis is now medically defined by various interaction patterns between microorganisms and their residing hosts, best exemplified by the bacterial endosymbiont Wolbachia identified in arthropods and filarial nematodes, which can influence normal development, reproduction, survival and transmission of the hosts. Based on the transmission modes, vertical or horizontal, and the function of the endosymbionts, the host-symbiont dependence can be divided into primary or secondary. In dermatology, the role of endosymbionts in skin ectoparasitosis has aroused great interests in the past years. Riesia pediculicola is a primary bacterial endosymbiont in body lice Pediculus humanus, and supplement their hosts with vitamin B, especially pantothenic acid. In cimicosis, the Gram-negative Wolbachia can synthesize biotin and riboflavin, which are crucial for the growth and reproduction of the bedbug Cimex lectularius. In human demodicosis and rosacea, further study is required to prove the pathogenic role of the Gram-negative bacteria Bacillus oleronius or the Gram-positive bacteria Bacillus cereus demonstrated in the Demodex mites. The high infection rate of adult female ticks Ixodes ricinus with the Gram-negative bacteria Midichloria mitochondrii present in the mitochondria in diverse ovarian cells, with the high seroprevalence rate in tick-exposed subjects, raises the possibility that this non-pathogenic endosymbiont may play a role in immune response and successful transmission of the tick-borne pathogen. The anaerobic protozoan Trichomonas vaginalis and bacteria Mycoplasma hominis are two obligate parasites in the urogenital epithelium, with partially overlapping symptoms. Intracellular localization of Mycoplasma hominis can avoid host immune response and penetration of antibiotics, while Trichomonas vaginalis infected with Mycoplasma hominis seems to have a higher cytopathic activity and amoeboid transformation rate. Further study on the biology and pathogenesis of different endosymbionts in dermatological parasitosis will help for the development of new treatment modalities.
