BACKGROUND: In countries with elevated prevalence of zoonotic anisakiasis and high awareness of this parasitosis, a considerable number of cases that associate Anisakis sp. (Nematoda, Anisakidae) and different bowel carcinomas have been described. Although neoplasia and embedded larvae were observed sharing the common site affected by chronic inflammation, no association between the nematode and malignancy were directly proved. Similarly, no data are available about the effect of secretory and excretory products of infecting larvae at the host's cellular level, except in respect to allergenic interaction...

Based on a case report an overview on the differential diagnostic considerations with respect to blood hypereosinophilia (HE) and hypereosinophilic syndromes (HES) in childhood is given. A 13-year-old boy was admitted for the clarification of an asthma. In the blood count an increased HE with 3 500/µl (30%) was found along with elevated total serum IgE and IL-5 level (2 000 IU/ml and 17 pg/ml). Lung function showed an obstruction (FEV1 38%). Radiologically the picture of bronchiectasis and mucus pluggine appeared...

Scabies is a common parasitosis, occurring worldwide and at any age that impairs the quality of life of patients and their families by the itching and the stigmatization. The main aims of therapy are destroying the mites Sarcoptes scabiei var. hominis that infect the stratum corneum and reduction of the itching. This requires detailed clarification for the patients and the parents of affected children as the instructions for the use of the drugs and also the necessary additional steps are often not correctly followed...

Individuals with obsessive-compulsive features frequently visit dermatologists for complaints of the skin, hair, or nails, and often progress towards a chronic relapsing course due to the challenge associated with accurate diagnosis and management of their psychiatric symptoms. The current DSM-5 formally recognizes body dysmorphic disorder, trichotillomania, neurotic excoriation, and body focused repetitive behavior disorder as psychodermatological disorders belonging to the category of Obsessive Compulsive and Related Disorders...

Ekbom syndrome or delusional parasitosis is a rare disease characterized by the unwavering conviction of having cutaneous infestation of insects or parasites. This is a monothematic delusion of hallucinatory origin that typically affects older women. We report the case of three patients with delusional parasitosis in different clinical settings. The first patient suffered from isolated delusional parasitosis corresponding to the condition described by Karl Ekbom. The second case suffered from secondary delusional parasitosis, occurring in the setting of leukoencephalopathy (CADASIL)...

Irritable bowel syndrome (IBS) is a functional disorder of the gastrointestinal tract characterised by multi-factorial aetiology. In IBS physiopathology are involved diverse factors between them biological, psychosocial, and environmental components which affect the immune activation status of gut mucosa. Among these factors is recognized the intestinal parasitosis. Post-infection IBS (PI-IBS) is recognised as a subgroup of functional disorders whose symptoms onset appear after a symptomatic intestinal infection caused by microbial agents...

Echinococcosis (hydatidosis) is a rare severe tissue parasitosis. In the Czech Republic it is caused by two species of tapeworm: Echinococcus granulosus or Echinococcus multilocularis. The species differ in both their usual hosts during their life cycle as well as in the typical form of lesions in infested tissues. In both cases the liver is the most common primary infested organ.We describe an autopsy case of a massive hepatic parasitic lesion in an 81 year-old man. There were metastatic parasitic cysts in both lungs and the hepatic mass spread per continuitatem in the right adrenal gland...

Thelazia callipaeda (Spirurida, Thelaziidae) has been documented as agent of ocular infection in domestic animals (dogs and cats), wildlife (e.g., foxes, hares, rabbits), and humans. In the last two decades, this parasitosis has been increasingly reported in several European countries. Both adult and larval stages of the eyeworm are responsible for symptoms ranging from mild (e.g., lacrimation, ocular discharge, epiphora) to severe (e.g., conjunctivitis, keratitis, and corneal opacity or ulcers). The present study evaluated the clinical efficacy and safety of imidacloprid 10% and moxidectin 2...

Anisakis species are marine nematodes which can cause zoonotic infection in humans if consumed in raw, pickled or undercooked fish and seafood. Infection with Anisakis is associated with abdominal pain, nausea and diarrhoea and can lead to massive infiltration of eosinophils and formation of granulomas in the gastrointestinal tract if the larvae are not removed. Re-infection leads to systemic allergic reactions such as urticarial or anaphylaxis in some individuals, making Anisakis an important source of hidden allergens in seafood...

The Global Programme to Eliminate Lymphatic Filariasis has two main components: interrupting transmission of lymphatic filariasis (LF) and managing morbidity and preventing disability. However, interventions to prevent and manage LF-related disabilities in endemic communities have been of limited extent. The aim of this study was to describe the prevalence of morbidity and its correlation with filarial infection, thereby filling a gap that existed regarding the data on morbidity in Brazil. Presence of Wuchereria bancrofti microfilaria was investigated using the thick smear technique...

Ascaris lumbricoides is responsible for a highly disseminated helminth parasitic disease, ascariosis, a relevant parasitosis that responds for great financial burden on the public health system of developing countries. In this work, metabolic fingerprinting using high-resolution mass spectrometry (HRMS) was employed to identify marker molecules from A. lumbricoides in different development stages. We have identified nine biomarkers, such as pheromones and steroidal prohormones in early stages, among other molecules in late development stages, making up four molecules for fertilized eggs, four marker molecules for first larvae (L1) and one marker molecule for third larvae (L3)...

INTRODUCTION: Toxocariasis is a parasitosis which complicates the accidental infestation of the humans by larvae of a roundworms belonging of the genus Toxocara. In adults, the discovery is often incidental during a hypereosinophilia check-up. Clinical signs are not specific and depend on affected organs. CASE REPORT: We report the case of a 53-year-old-woman who has consulted for a recent cough, after spontaneous resolution of abdominal pain. The laboratory examination isolated an hypereosinophilia and the liver sonography showed two hypoechogenic nodules...

Dirofilariasis by Dirofilaria repens is an important mosquito vector borne parasitosis, and the dog represents the natural host and reservoir of the parasite. This filarial nematode can also induce disease in humans, and in the last decades an increasing number of cases have been being reported. The present study describes the first loop mediated isothermal amplification (LAMP) assay to detect D. repens DNA in blood and mosquitoes. Two versions of the technique have been developed and described: in the first, the amplification is followed point by point through a real time PCR instrument (ReT-LAMP); in the second, the amplification is visualized by checking UV fluorescence of the reaction mixture after addition of propidium iodide (PI-LAMP)...

Gnathostomiasis is a zoonotic parasitosis endemic in many Asian and some Latin American countries. Most human infections are caused by Gnathostoma spinigerum in Asia and Gnathostoma binucleatum in the Americas, and recently, imported cases have been increasing among travelers returning from endemic regions. Confirmation of the clinical diagnosis relies largely on serologic tests, with a G. spinigerum-antigen-based immunoblot currently being the diagnostic method of choice. However, we repeatedly experienced that sera from patients with clinically suspected American gnathostomiasis gave negative results in this assay...

Chagas disease, caused by Trypanosoma cruzi, is a parasitosis that predominates in Latin America. It is estimated that 25 million people are under the risk of infection and, in 2008, more than 10 thousand deaths were registered. The only two drugs available in the therapeutics, nifurtimox and benznidazole, showed to be more effective in the acute phase of the disease. However, there is no standard treatment protocol effective for the chronic phase. Nitrofurazone (NF), an antimicrobial drug, has activity against T...

Scabies is a common, highly contagious skin parasitosis caused by Sarcoptes scabiei var. hominis. Early identification and prompt treatment of infested subjects is essential, as missed diagnosis may result in outbreaks, considerable morbidity, and significantly increased economic burden. The standard diagnostic technique consists of mites' identification by microscopic examination of scales obtained by skin scraping. This is a time-consuming and risk-associated procedure that is also not suitable to a busy practice...
