Rickettsioses in Brazil: distinct diseases and new paradigms for epidemiological surveillance
Abstract Bed bugs are hematophagous arthropods that can parasitize humans. During the coronavirus disease pandemic, there has been an increase in elderly neglect. A man in his 90s came to the hospital complaining of generalized pruritus. Despite being a dependent patient, he was left alone in a home by his relatives during the pandemic. Examination revealed inflammatory nodules in addition to a live bed bug crawling over his trunk. Identifying a bed bug during consultation is an uncommon feature that can help determine a particular diagnosis. As this case shows, the need for social isolation during pandemics can contribute...

Improving Diagnosis of Hepatitis C Virus Infection Using Hepatitis C Core Antigen Testing in a Resource-Poor Setting
CONCLUSIONS: The Architect HCV core antigen assay is highly specific and has an excellent positive predictive value. At the present level of sensitivity (77%), the study is still relevant in a low-income setting in which most of the HCV-positive patients would go undiagnosed, since HCV RNA testing is not available and/or not affordable. HCV core antigen testing can also help determine the true burden of infection in a population, considering the fact that almost 50% of the anti-HCV positive cases are negative for HCV RNA.

Therapeutic effects of virtual reality video gaming on functional mobility, balance, and gait speed in individuals with tropical spastic paraparesis: A randomized crossover clinical trial
Abstract INTRODUCTION: Individuals with human T-cell lymphotropic virus 1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) experience sensorimotor alterations, which can affect functional performance. Virtual reality (VR) videogaming is a therapeutic option, though there is scarce evidence for its use in this population. We aimed to investigate the therapeutic effects of a VR video game on functional mobility, balance, and gait speed in individuals with HAM/TSP. METHODS: We conducted a blinded, crossover clinical trial comprising 29 individuals with HAM/TSP and randomized them into two groups: (1) early therapy...

Role of aminoglycoside-modifying enzymes and 16S rRNA methylase (ArmA) in resistance of Acinetobacter baumannii clinical isolates against aminoglycosides
CONCLUSIONS: High minimum inhibitory concentration of aminoglycosides in isolates with the simultaneous presence of AME- and ArmA-encoding genes indicated the importance of these genes in resistance to aminoglycosides. However, control of their spread could be effective in the treatment of infections caused by A. baumannii. (Source: Revista da Sociedade Brasileira de Medicina Tropical)

Functional capacity and rehabilitation strategies in Covid-19 patients: current knowledge and challenges
Abstract Covid-19 is a novel infectious disease whose spectrum of presentation ranges from absence of symptoms to widespread interstitial pneumonia associated with severe acute respiratory syndrome (SARS), leading to significant mortality. Given the systemic pattern of Covid-19, there are many factors that can influence patient's functional capacity after acute infection and the identification of such factors can contribute to the development of specific rehabilitation strategies. Pulmonary impairment is the primary cause of hospitalization due to Covid-19, and can progress to SARS as well as increase length of hospitaliza...

Bee sting envenomation severe cases in Manaus, Brazilian Amazon: clinical characteristics and immune markers of case reports
We report two cases of severe bee envenomation, of which one was fatal. We also describe clinical characteristics and immune markers. Both victims suffered from respiratory distress, renal failure, rhabdomyolysis, and shock. They required invasive mechanical ventilation, vasoactive drugs, and renal replacement therapy. Moreover, serum levels of chemokines, cytokines, and cell-free circulating nucleic acids demonstrated an intense inflammatory process. Massive envenoming produced systemic injury in the victims, with an uncontrolled inflammatory response, and a more significant chemotactic response in the fatal case. (Source...

Report of envenomation in humans by handling a dyeing poison frog Dendrobates tinctorius (SCHNEIDER, 1799) (Anura: Dendrobatidae) in the Amazon, Brazil
We report a case of envenomation by Dendrobates tinctorius in the northwest of the Amazon Forest. The patients were two men, who presented with numbness in the right arm and slight numbness in the lower lip, respectively. Dendrobates tinctorius secretions contain pumiliotoxin, one of several toxins found in the dendrobatidis skin, which interferes with muscle contraction and causes locomotor difficulties. Although Dendrobatidae is a family of anurans known for their venom, few studies describe the symptoms of envenomation in humans. (Source: Revista da Sociedade Brasileira de Medicina Tropical)
