Objective: This study aims to estimate the prevalence of thyroid diseases and anti-TPO status. We searched for an association among presence of immune reconstitution and use of stavudine, didanosine and protease inhibitors with thyroid diseases. Materials and methods: A cross-sectional study was performed to analyze the records of 117 HIV-infected patients who had their CD4 + cell count, viral load, anti-TPO, TSH and free T 4 levels collected on the same day. Immune reconstitution was considered in those whose T CD4 + count was below 200 cells/mm³, but these values increased above 200 cells/mm³ after the use of antiretrovirals. The odds ratio obtained by a 2x2 contingency table and a chi-square test were used to measure the association between categorical variables. Results: The prevalence of thyroid disease was 34.18%; of these, 4.34% were positive for anti-TPO. There was an association of risk between stavudine use and subclinical hypothyroidism (OR = 4.19, 95% CI: 1.29 to 13.59, X² = 6.37, p = 0.01). Immune reconstitution achieved protection associated with thyroid disease that was near statistical significance OR = 0.45, 95% CI: 0.19 to 1.04, X² = 3.55, p = 0.059.
Conclusion:The prevalence of thyroid disease in the sample studied was higher than what had been found in the literature, with a low positive anti-TPO frequency. The historical use of stavudine has an association of risk for the presence of subclinical hypothyroidism, and immune reconstitution has trends towards protection for the presence of thyroid diseases.

Visceral leishmaniasis is an anthropozoonosis that is caused by protozoa
of the genus Leishmania, especially Leishmania
(Leishmania) infantum, and is transmitted to
humans by the bite of sandflies of the genus Lutzomyia, such as
Lutzomyia longipalpis. There are many reservoirs, including
Canis familiaris. It is a chronic infectious disease with
systemic involvement that is characterized by three phases: the initial period, the
state period and the final period. The main symptoms are fever, malnutrition,
hepatosplenomegaly, and pancytopenia. This article reports a case of a patient
diagnosed with visceral leishmaniasis in the final period following autochthonous
transmission in the urban area of Rio de Janeiro. The case reported here is
considered by the Municipal Civil Defense and Health Surveillance of Rio de Janeiro
to be the first instance of autochthonous visceral leishmaniasis in humans in the
urban area of this city. The patient was discharged and is undergoing a follow-up at
the outpatient clinic, demonstrating clinical improvement.
Syphilis has been coined “the great imitator” due to its extreme heterogeneity of presentation and mimicry of other conditions. Therefore, it is essential that physicians be familiar with the full spectrum of its manifestations. Syphilis may also lead to oral lesions that, occasionally, are unaccompanied by concomitant tegumentary findings. Such patients will pose unique diagnostic challenges. We report the case of a 45-year-old HIV-infected male patient in whom secondary syphilis presented with burning mouth and dysgeusia that progressed to glossodynia and odynophagia. Examination revealed painful, shallow erosions on the posterior aspect of the tongue, in a pattern of plaques en prairie fauchée. A painful split papule (fausse perlèche or false angular cheilitis) was also present in the left commissure. There were no cutaneous lesions. The oral lesions were considered highly suggestive of secondary syphilis. A novel VDRL assay (which was previously negative) yielded a titer of 1/128. Complete clinical remission was rapidly achieved after initiation of penicillin therapy. A comprehensive review of the literature on oral manifestations of syphilis is offered.
Sporotrichosis is a human and animal disease caused by dimorphic pathogenic species of the genus Sporothrix. We report a dramatic presentation of Sporothrix brasiliensis infection, with destruction of the nasal septum, soft palate, and uvula of an HIV-infected woman. She was successfully treated with amphotericin B deoxycholate followed by itraconazole. Sporotrichosis remains a neglected opportunistic infection in patients with AIDS and awareness of this potentially fatal infection is of utmost importance.
SUMMARYEnvenoming syndrome from Africanized bee stings is a toxic syndrome caused by the inoculation of large amounts of venom from multiple bee stings, generally more than five hundred. The incidence of severe toxicity from Africanized bee stings is rare but deadly. This report reveals that because of the small volume of distribution, having fewer stings does not exempt a patient from experiencing an unfavorable outcome, particularly in children, elderly people or underweight people.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
