[Pulmonary parasitoses. General aspects].

Parasite diseases of the lung comprise a wide group of nosological entities. The main parasite diseases of the lung (malaria, ambiasis, bilharziosis, distomatosis, hydatidiasis) as well as the eosinophilic lung will be discussed in specific articles in the journal. Other parasite diseases of the lung are discussed here after studying the general aspects of pulmonary parasite diseases.

Mucocutaneous manifestations of helminth infections: Trematodes and cestodes.

In the 21st century, despite increased international travel for vacation, work, and medical missions and immigration into the United States, there is little published in the dermatology literature regarding the cutaneous manifestations of helminth infections. It has been estimated that 20% to 70% of international travelers suffer from some travel-related health problem. Approximately 17% of travelers seek medical care because of cutaneous disorders, many related to infectious etiologies. This review will focus on cutaneous diseases caused by helminth infections. Part I of the review focused on

Acute morbidity associated with scabies and other ectoparasitoses rapidly improves after treatment with ivermectin.

In resource-poor settings, scabies is associated with considerable morbidity. Which factors determine morbidity and how rapidly it recedes after specific treatment is not known. Patients with scabies were recruited in three urban slums in Fortaleza, Northeast Brazil. Diagnosis was established according to dermatoscopy, skin scraping, or adhesive film test. Severity of scabies-associated morbidity was assessed semiquantitatively. Patients and close contacts were treated with oral ivermectin (200 μg/kg, repeated after 7 days) and followed up for 2 weeks. Ninety-five patients were included in the

Pulmonary toxocariasis masquerading as metastatic tumor nodules in a child with osteosarcoma.

A 14-year-old male, who completed chemotherapy following limb salvage surgery for osteosarcoma approximately 2 years ago, was seen for routine follow-up. A CT scan revealed new scattered multifocal nodular lesions. An ultrasonography-guided percutaneous needle biopsy was done to confirm pulmonary metastasis of the underlying osteosarcoma. The lung biopsy showed findings of eosinophilic pneumonia with no evidence of malignancy. Peripheral eosinophilia was also noted. When a more thorough history revealed frequent intake of raw cow liver, we diagnosed pulmonary toxocariasis by ELISA for specific

[The fate of parasites of animal origin transmitted to humans].

The fate of a parasite transmitted from an animal to man depends on the ability of the contaminating agent to reach a place where it can thrive, to find necessary nutrients, and to resist host defense mechanisms. The purpose of this study was to evaluate the incidence of transmission of parasites from animals to man and to determine to what extent transmission is followed by development. Stenoxenic parasites whose life cycle requires transmission from animals to man obviously develop in man and then return to animals. These parasites cause holozoonoses of the cyclozoonosis type. Some euryxenic

Naturally occurring human antiglobulins with specificity for E.

Human sera have been examined for antibodies with specific reactivity for gammaE using the tanned cell hemagglutination test. Cells tanned with three different gammaE myeloma proteins provided a reproducible test system. Inhibition of agglutination reactions by gammaE proteins, but not by gammaG, gammaA, gammaM, or gammaD confirmed the specificity of these reactions. 8.5% of 304 serial serum samples obtained from miscellaneous hospitalized patients showed clear-cut anti-gamma-globulins with specificity for gammaE. In most of these instances no definite clinical history of concomitant allergic

Secondary Myiasis in an Immunocompetent Patient With Severe Chromoblastomycosis.

This is the case of chronic chromoblastomycosis (CBM) in a 61-year-old male from the Dominican Republic (DR) with extensive cutaneous eruptions over multiple areas of the body including bilateral lower extremities and the flank extending to the back. A 61-year-old male with a history of morbid obesity, chronic kidney disease stage III, and well-controlled hypertension presented to the family medicine clinic for the evaluation of chronic painful skin lesions on his legs and torso. The lesions began 19 years prior, following a flood in the Dominican Republic (DR) where he was living at the time.

Manifestations of systemic disease in the retina and fundus of cats and dogs.

The fundus is unique in that it is the only part of the body that allows for a noninvasive and uninterrupted view of vasculature and nervous tissue. Utilization of this can be a powerful tool in uncovering salient incidental findings which point to underlying systemic diseases, and for monitoring response to therapy. Retinal venules and arterioles allow the clinician to assess changes in vascular color, diameter, outline, and tortuosity. The retina and optic nerve may exhibit changes associated with increased or decreased thickness, inflammatory infiltrates, hemorrhages, and detachments. While

Chronic pruritus: a narrative review.

Chronic pruritus encompasses a manifestation of several cutaneous, allergic, infectious, neurological, psychological, and systemic conditions, whose etiological investigation and therapeutic strategy can be challenging. This comprehensive review aims to enhance the understanding of pruritus by highlighting important elements in its pathogenesis, including keratinocytes, Merkel cells and mast cells, nerve fibers, histaminergic and nonhistaminergic pathways, and the interaction of itch signals with the central nervous system. Diagnostic evaluation of chronic pruritus may require a meticulous app

… toxocariasis is a parasitic disease characterized by the presence of larvae of the genus Toxocara in human tissues. 47 T. canis and T. cati , found in dog and cat intestines, respectively, are the most common causative agents of the disease. 47 Toxocaral larvae usually cause two severe syndromes: visceral larva … migrans and ocular larva migrans, depending on the location of the larvae. 47 iii Chronic pruritus related to neurogenic, neuropathic or central nervous system conditions Neuropathic pruritus Neuropathic pruritic conditions may originate from the peripheral nervous system or central nervous system …

Parasites revive hope for cancer therapy.

Parasites have attained a life-long stigma of being detrimental organisms with deleterious outcomes. Yet, recently, a creditable twist was verified that can dramatically change our perception of those parasites from being a source of misery to millions of people to a useful anti-cancerous tool. Various parasites have shown promise to combat cancer in different experimental models, including colorectal, lung, and breast cancers, among others. Helminths and protozoan parasites, as well as their derivatives such as Echinococcus granulosus protein KI-1, Toxoplasma gondii GRA15II, and Trypanosoma c
