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.

Malignant syphilis is an uncommon, but not unknown, ulcerative variation of secondary syphilis. The lesions typically begin as papules, which quickly evolve to pustules and then to ulcers with elevated edges and central necrosis. It is usually, but not mandatory, found in patients with some level of immunosuppression, such as HIV patients, when the TCD4(+) cell count is >200 cells/mm(3). Despite the anxiety the lesions cause, this form of the disease has a good prognosis. The general symptoms disappear right after the beginning of treatment, and lesions disappear over a variable period. This study reports the case of a 27-year-old man who has been HIV positive for 6 years, uses antiretroviral therapy incorrectly, has a TCD4(+) cell count of 340 cells/mm(3), a VDRL of 1:128 and itchy disseminated hyperchromic maculopapular lesions with rupioid crusts compatible with malignant syphilis.
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.
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.
Bacillary angiomatosis (BA) is an angioproliferative disease of immunocompromised
patients that usually presents as vascular tumors in the skin and subcutaneous
tissues. It is caused by chronic infections with either Bartonella
henselae or B. quintana. Oral cavity BA is exceedingly
rare and even rarer without simultaneous cutaneous disease. We report herein the case
of a 51-year-old HIV-infected man who presented severe odynophagia and an eroded
lesion on the hard palate that progressed to an oronasal fistula. No cutaneous
lesions were recorded. Doxycycline led to complete resolution. To the best of our
knowledge, only six previous cases of oral BA without tegumentary disease have been
previously reported and none of them progressed to fistula.
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.
Pyoderma gangrenosum received this name due to the notion that this disease was related to infections caused by bacteria in the genus Streptococcus. In contrast to this initial assumption, today the disease is thought to have an autoimmune origin. Necrotizing fasciitis was first mentioned around the fifth century AD, being referred to as a complication of erysipelas. It is a disease characterized by severe, rapidly progressing soft tissue infection, which causes necrosis of the subcutaneous tissue and the fascia. On the third day of hospitalization after antecubital venipuncture, a 59-year-old woman presented an erythematous and painful pustular lesion that quickly evolved into extensive ulceration circumvented by an erythematous halo and accompanied by toxemia. One of the proposed etiologies was necrotizing fasciitis. The microbiological results were all negative, while the histopathological analysis showed epidermal necrosis and inflammatory infiltrate composed predominantly of dermal neutrophils. Pyoderma gangrenosum was considered as a diagnosis. After 30 days, the patient was discharged with oral prednisone (60 mg/day), and the patient had complete healing of the initial injury in less than two months. This case was an unexpected event in the course of the hospitalization which was diagnosed as pyoderma gangrenosum associated with myelodysplastic syndrome.
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.
