Introduction: Chagas disease (CD) is caused by Trypanosoma cruzi. When acquired, the disease develops in stages. For diagnosis, laboratory confirmation is required, and an extensive assessment of the patient’s health should be performed. Treatment consists of the administration of trypanocidal drugs, which may cause severe adverse effects. The objective of our systematic review was to analyze data contained in the CD published case reports to understand the challenges that patients and clinicians face worldwide. Materials and methods: We performed a systematic review following the PRISMA guidance. PubMed database was explored using the terms ‘American trypanosomiasis’ or ‘Chagas disease’. Results were limited to human case reports written in English or Spanish. A total of 258 reports (322 patients) were included in the analysis. Metadata was obtained from each article. Following this, it was analyzed to obtain descriptive measures. Results: From the sample, 56.2% were males and 43.8% were females. Most cases were from endemic countries (85.4%). The most common clinical manifestations were fever during the acute stage (70.0%), dyspnea during the chronic stage in its cardiac form (53.7%), and constipation during the chronic stage in its digestive form (73.7%). Most patients were diagnosed in the chronic stage (72.0%). Treatment was administered in 56.2% of cases. The mortality rate for the acute stage cases was 24.4%, while for the chronic stage this was 28.4%. Discussion: CD is a parasitic disease endemic to Latin America, with increasing importance due to human and vector migration. In this review, we report reasons for delays in diagnosis and treatment, and trends in medical practices. Community awareness must be increased to improve CD’s diagnoses; health professionals should be appropriately trained to detect and treat infected individuals. Furthermore, public health policies are needed to increase the availability of screening and diagnostic tools, trypanocidal drugs, and, eventually, vaccines.

Abstract Purpose Villoglandular adenocarcinoma (VGA) of the uterine cervix has been classified as a rare subtype of cervical adenocarcinoma with good prognosis. A conservative surgical approach is considered feasible. The main risk factor is the presence of other histologic types of cancer. In this largest systematic review to date, we assess oncological outcomes associated with conservative therapy compared to those associated with invasive management in the treatment of stage Ia and Ib1 VGA. Methods Case series and case reports identified by searching the PubMed database were eligible for inclusion in this review (stage Ia–Ib1). Results A total of 271 patients were included in our literature review. 54 (20%) patients were treated by “conservative management” (conization, simple hysterectomy, and trachelectomy) and 217 (80%) by “invasive management” (radical hysterectomy ± radiation, hysterectomy, and radiation). Recurrences of disease (RODs) were found in the conservative group in two (4%) cases and in the invasive group in nine (4%) cases. There was no significant difference in disease-free survival (DFS) according to conservative or invasive treatment (p = 0.75). The histology of VGA may be complex with underlying usual adenocarcinoma (UAC) combined with VGA. Conclusion The excellent prognosis of pure VGA and the young age of the patients may justify the management of this tumor using a less radical procedure. The histological diagnosis of VGA is a challenge, and pretreatment should not be based solely on a simple punch biopsy but rather a conization with wide tumor-free margins.

AbstractChagas disease (CD) is a parasitic infection caused by Trypanosoma cruzi protozoa. Over 8 million people worldwide are T. cruzi-positive, 20-30% of which will develop cardiomyopathy, megaoesophagus and/or megacolon. The mechanisms leading to gastrointestinal (GI) symptom development are however poorly understood. To address this issue, we systematically characterized the spatial impact of experimental T. cruzi infection on the microbiome and metabolome across the GI tract. The largest microbiota perturbations were observed in the proximal large intestine in both acute and chronic disease, with chronic-stage effects also observed in the cecum. Strikingly, metabolomic impact of acute-to-chronic stage transition differed depending on the organ, with persistent large-scale effects of infection primarily in the oesophagus and large intestine, providing a potential mechanism for GI pathology tropism in CD. Infection particularly affected acylcarnitine and lipid metabolism. Building on these observations, treatment of infected mice with carnitine-supplemented drinking water prevented acute-stage mortality with no changes in parasite burden. Overall, these results identified a new mechanism of disease tolerance in CD, with potential for the development of new therapeutic regimens. More broadly, these results highlight the potential of spatially-resolved metabolomic approaches to provide insight into disease pathogenesis, with translational applications for infectious disease drug development.

Background and Aim: Co-infection of COVID-19 with other respiratory pathogens which may complicate the diagnosis, treatment, and prognosis of COVID-19 emerge new concern. The overlap of COVID-19 and influenza, as two epidemics at the same time can occur in the cold months of the year. The aim of current study was to evaluate the rate of such co-infection as a systematic review and meta-analysis.Methods: A systematic literature search was performed on September 28, 2019 for original research articles published in Medline, Web of Science, and Embase databases from December 2019 to September 2020 using relevant keywords. Patients of all ages with simultaneous COVID-19 and influenza were included. Statistical analysis was performed using STATA 14 software.Results: Eleven prevalence studies with total of 3,070 patients with COVID-19, and 79 patients with concurrent COVID-19 and influenza were selected for final evaluation. The prevalence of influenza infection was 0.8% in patients with confirmed COVID-19. The frequency of influenza virus co-infection among patients with COVID-19 was 4.5% in Asia and 0.4% in the America. Four prevalence studies reported the sex of patients, which were 30 men and 31 women. Prevalence of co-infection with influenza in men and women with COVID-19 was 5.3 and 9.1%, respectively. Eight case reports and 7 case series with a total of 123 patients with COVID-19 were selected, 29 of them (16 men, 13 women) with mean age of 48 years had concurrent infection with influenza viruses A/B. Fever, cough, and shortness of breath were the most common clinical manifestations. Two of 29 patients died (6.9%), and 17 out of 29 patients recovered (58.6%). Oseltamivir and hydroxychloroquine were the most widely used drugs used for 41.4, and 31% of patients, respectively.Conclusion: Although a low proportion of COVID-19 patients have influenza co-infection, however, the importance of such co-infection, especially in high-risk individuals and the elderly, cannot be ignored. We were unable to report the exact rate of simultaneous influenza in COVID-19 patients worldwide due to a lack of data from several countries. Obviously, more studies are needed to evaluate the exact effect of the COVID-19 and influenza co-infection in clinical outcomes.

ABSTRACT Chagas’ disease is an emerging public health problem in areas where the disease is not endemic. Treatment with benznidazole has shown efficacy in the acute stage of the disease, but its efficacy in the chronic stage remains controversial, and unwanted side effects are more frequent and severe in adults than in children. This study describes the profile of side effects of benznidazole in a cohort of Trypanosoma cruzi-infected patients in a European country.

Objectives: Biological medications have been used with an increasing frequency to treat rheumatological diseases. Autoimmune events can be induced by these drugs, such as psoriasiform lesions, alopecia, lupus and, vasculitis, which more often affects the skin (small-sized vessels) and eventually other organs. In this review, we describe the clinical profile of patients with vasculitis induced by the main biological agents used in rheumatology. Patients and methods: We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. The PubMed database was used for searching eligible articles. We included case reports, case series, and letter to the editor of patients on anti-tumor necrosis factor-alpha (anti-TNF-a) molecules, as well as tocilizumab, ustekinumab, secukinumab, rituximab, and abatacept, who had vasculitis induced by these agents. Results: Eighty-one articles were included for final analysis (n=89). Twenty-seven patients were using infliximab, 20 adalimumab, 18 etanercept, seven secukinumab, four certolizumab, four rituximab, three golimumab, three ustekinumab, two abatacept, and one tocilizumab. Unspecific leukocytoclastic vasculitis (LCV) was the most common type of vasculitis (n=37), followed by anti-neutrophil cytoplasmic antibody (ANCA)- associated vasculitis (n=16). The medication was replaced with another biological molecule in 23 cases, with only four relapses. In six cases, the biological was maintained, but vasculitis worsened/persisted in one case, being necessary drug removal. Conclusion: Infections, infusion reaction, cancer, and autoimmune events are well-known side effects of biological therapy. This review demonstrates that vasculitis is another adverse effect of this type of therapy, particularly the anti-TNF-a molecules, and LCV the most reported type of vasculitis.

AbstractOrthopedic injuries commonly affect children during earthquakes, but reports about them are rare. This setting may lead to different standards of care, but guidelines are still missing in this field. A systematic review was performed to: (1) assess type and body distribution of pediatric earthquake-related injuries, treatment performed, length of stay, and complications; and (2) identify starting points to define standards of care.PubMed database was researched for papers (1999-2014 period) in agreement with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. Inclusion criteria were: English, French, Spanish, or Italian language and data reported about orthopedic lesions in children (≤18 years old). Reviews, letters, commentaries, editorials, and single case reports were excluded. Two independent reviewers selected articles after abstract and full-text reading.Traumatic injuries caused child hospital admissions ranging from 46.9% to 100.0%; 16% to 53% suffered fractures. Lower limbs mostly were involved. Soft-tissue injuries affected 55% of patients. Debridement and external fixation (EF) were the most frequent surgical treatments. Amputation rates varied from 5% to 11%.This study revealed that field hospitals should be prepared to: (1) treat mainly lower extremities fractures in children; and (2) use especially EF techniques. The presence of orthopedic surgeons familiar with pediatric traumatology should be considered.MorelliI, SabbadiniMG, BortolinM.

AbstractVisceral leishmaniasis is an important neglected parasitic disease that is generally caused byLeishmania infantum,Leishmania donovaniandLeishmania chagasi. However, several causative species of cutaneous leishmaniasis (CL) causes an interstitial form of leishmaniasis which known viscerotropic leishmaniasis. The aim of this paper is a systematic review of the cases of viscerotropic leishmaniasis to present the main causative agents, clinical manifestations, treatment and outcomes of the cases. An electronic search (any date to August 2017) without language restrictions was performed using Medline, PubMed, Scopus and Google Scholar. The searches identified 19 articles with total 30 case reports. Of them, old worldLeishmaniaspecies was reported from 23 (76.7%) cases, including 20 cases ofL. tropicaand three cases ofL. major; whereas new worldLeishmaniaspecies were reported in seven (23.4%) cases. The infection was more prevalent in male (24/30, 80%) than female (5/30, 16.7%) patients. Co-morbidity/co-infection was observed in 13 out of 30 cases (43.4%), which the most of them was HIV/AIDS (10 out of 13 cases, 76.9%). The results suggested that viscerotropic leishmaniasis should be more attended in the endemic countries of CL and in immunocompromised patients in order to exact discrimination from other endemic infectious diseases.

Background: The most plausible hypothesis for takotsubo cardiomyopathy (TCM) is a catecholamine surge. Direct administration of catecholamines or medications causing catecholamine surge is frequently used in clinical practice. Methods: A Medline/PubMed database search was conducted for case reports or series of drug-induced TCM. All reported cases of drug-induced TCM were systemically identified and analyzed. Results: We identified 157 cases of drug-induced TCM. Fifty-seven (36.3%) cases were related to the administration of exogenous catecholamines. In 50 (31.9%) other cases, there was potential adrenergic effect. This included drugs with adrenergic vasoconstriction properties (3.2%), hyperadrenergic state due to alcohol or opioid withdrawal (7.7%), inhibitors of catecholamine reuptake (14.7%), anaphylactic reaction that is accompanied by catecholamine release (3.2%), and psychological or somatic stress coinciding with the administration of a drug that was thought to be the culprit (3.2%). Overall, 68.2% of these drug-induced TCM cases were catecholamine related. In 14 (8.9%) cases, the likely etiology of cardiomyopathy was chemotherapy-induced coronary vasospasm. Conclusion: Our systematic review showed that over two-thirds of drug-induced TCM cases were due to direct or indirect catecholamine stimulation. The lowest effective dose and shortest duration of catecholamines should be utilized, and alternative therapies should be considered if feasible.
