infectious diease

Leprosy is an infectious and contagious disease of slow evolution, triggered by Mycobacterium leprae . Arthritis is its third most common manifestation, after cutaneous and peripheral nerve involvement. Since musculoskeletal symptoms may be the initial presentation of the disease, it is important for health professionals to recognize its rheumatic manifestations for early diagnosis and appropriate treatment, especially in endemic areas. In addition, cases of leprosy have increased globally, notably in patients undergoing treatment with TNF-α blockers and due to the increase in migration and travel of people from developing countries to developed countries...

Before the molecular age, cell culture was the gold standard for confirmatory diagnosis of viral and atypical infectious diseases. Typical cell culture methodologies are costly, require days (or weeks) for results, and require significant technical expertise. As a result, cell culture is impractical for timely diagnostic testing in most of the health care environments. Traditional bacterial culture methods, also have disadvantages due to the need for incubation, subsequent identification of pathogens, and significant technical expertise...

BACKGROUND: The ability of antituberculosis drugs to cross the blood-brain barrier and reach the central nervous system is critical to their effectiveness in treating tuberculosis meningitis (TBM). We sought to fill a critical knowledge gap by providing data on the ability of new and repurposed antituberculosis drugs to penetrate into the cerebrospinal fluid (CSF). METHODS: We conducted a clinical pharmacology study among patients treated for TBM in Tbilisi, Georgia, from January 2019 until January 2020...

Guillain-Barré syndrome (GBS) is an immune-mediated disease of the peripheral nervous system that is triggered by both infectious processes and post-immunization conditions. It is, therefore, more prevalent during infectious outbreaks. While the classical clinical presentation of ascending paralysis is easy to recognize, GBS is a heterogeneous entity comprising several variants, atypical presentations, and incomplete forms that may make the diagnosis challenging. Early recognition is key because the disease could be rapidly fatal...

The COVID-19 pandemic has brought humanity's strained relationship with nature into sharp focus, with calls for cessation of wild meat trade and consumption, to protect public health and biodiversity.1 , 2 However, the importance of wild meat for human nutrition, and its tele-couplings to other food production systems, mean that the complete removal of wild meat from diets and markets would represent a shock to global food systems.3-6 The negative consequences of this shock deserve consideration in policy responses to COVID-19...

There are six diseases that WHO considers as the major threat in developing countries, leprosy, filariasis, malaria, schistosomiasis, Chagas disease and leishmaniasis; and of these only malaria does not present skin lesions. These diseases are among the so called tropical diseases found in countries of tropical climate, usually infections and infestations considered exotic and rare in European and North American countries. It is extremely important for doctors of all countries to be able to provide correct pre travel counseling and to make early diagnosis and treatment, thus avoiding dissemination of these dieases to non endemic areas...

BACKGROUND: The treatment of infectious oral lesions is an important prophylactic procedure preceding immunsuppressive therapy. The case reported underlines the importance of this treatment by showing severe complications of an infective dental focus in an immunocompetent patient. CASE REPORT: A 65 year old patient was referred to hospital due to neurological disorders including hypaesthesia, movement deficits, nausea and falls. Because of progressive aggravation with hemiplegia a craniotomy and biopsy of a suspicious area in the pons was performed...

A sample survey was conducted in three public ambulatory medical care units in Rio de Janeiro in order to show the demographic and nosological aspects of the clientele as well as to evaluate the quality of clinic records. The sample included 2,029 patients registered in the health clinics and 3,980 consultants from October 1, 1990 to September 30, 1991. The diagnoses were coded according to the 9th revision of the International Classification of Dieases. Females accounted for about 60% of the sample, and more than a half were between 15 and 49 years of age...

Various workers, including T. D. Stewart, claim that the aboriginal Americas were relatively disease-free because of the bering Strait cold-screen, eliminating many pathogens, and the paucity of zoonotic infections because of few domestic animals. Evidence of varying validity suggests that precontact Americns had their own strains of treponemic infections, bacillary and amoebic dysenteries, influenza and viral penumonia and other respiratory diseases, salmonellosis and perhaps other food poisoning, various arthritides, some endoparasites such as the ascarids, and several geographically circumscribed diseases such as the rickettsial verruca (Carrion's disease) and New World leishmaniasis and trypanosomiasis...
