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.

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.

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.

Background: Cutaneous leishmaniasis is a prevalent communicable disease in low- and middle-income countries, where non-communicable diseases like skin cancer are on the rise. However, the study of multi-morbidity or co-morbidity between communicable and non-communicable diseases is limited, and even null for some tropical or neglected diseases. Nevertheless, looking at these conditions together instead of as isolated entities in places where these illnesses exist, could show new prevention and treatment paths. We aimed to summarize and critically appraise the epidemiological evidence on the association between cutaneous leishmaniasis and skin cancer. Methods: Following the PRISMA guidelines, we conducted a systematic review using five search engines (Embase, Medline, Global Health, Scopus and Web of Science). We sought observational studies in which the outcome was skin cancer whilst the exposure was cutaneous leishmaniasis; these conditions should have had laboratory or pathology confirmation. Results: No epidemiological investigations have studied the association between cutaneous leishmaniasis and skin cancer. Most of the evidence about the association of interest is still based on case reports and other clinical observations rather than strong epidemiological observational studies. Conclusions: Research is much needed to verify the repeatedly clinical observation that cutaneous leishmaniasis may be a risk factor for skin cancer. This evidence could inform and guide early diagnosis or prevention of skin cancer in survivors of cutaneous leishmaniasis or where cutaneous leishmaniasis is still highly prevalent.

Different Levels

The Leishmania donovani complex is considered to be composed of 3 species; L. donovani, L. infantum and L. chagasi, although this classification has been challenged. Genotypic relationships within the complex were evaluated at different levels by: binding of the probe Lmet9, specific for L. chagasi and Old World Leishmania spp.; partial sequencing of a constitutive major surface protease single gene (mspC) and random amplification of polymorphic DNA (RAPD). The Old World Leishmania spp. and the L. donovani complex have a monophyletic origin. Leishmania chagasi clearly belongs to the L. donovani complex but it is indistinguishable from L. infantum, which suggests introduction of L. chagasi into the New World in recent history. Leishmania infantum/L. chagasi was identified as a monophyletic group within the L. donovani complex but L. donovani may be paraphyletic. Diversity within L. donovani is substantial and phylogeographical patterns of association were found.

Introduction: Several observational studies have found parallels between COVID-19 pneumonia and organizing pneumonia (OP). This study aims to investigate the published literature of OP related to COVID-19, estimates the prevalence of OP among COVID-19 patients, and assesses the risk or COVID-19 severity associated with OP. Methodology: This was a systematic review and meta-analysis. A systematic electronic search through PubMed, Web of Science, Science Direct, EBSCO, and Google Scholar was conducted to include relevant and eligible literature. The authors used Review Manager 5.4 to perform quantitative data synthesis for the condition of interest analyses. Results: A total of 9 eligible study articles and 12 case reports were included in this study. The estimated pooled organizing pneumonia prevalence among COVID-19 patients was 45.6% [23.1%-68.2%]. The association between OP and severe COVID-19 infection revealed a pooled OR [95% CI] of 5.22 [-0.96-11.41]. Conclusion: COVID-19 patients had a rather high OP prevalence (43%). Surprisingly, cancer patients with COVID-19 infection had the lowest OP prevalence. OP was identified as a possible risk factor for the severity of COVID-19 infection.

Abstract Background Sugammadex is a modified gamma-cyclodextrin that acts by selectively encapsulating free amino-steroidal neuromuscular relaxants. Several case reports have been published on the use of sugammadex in patients with neuromuscular disorders that include neuromuscular junction diseases, myopathies, neuropathies, and motor neurone disorders. The primary aim of this review is to systematically review the evidence on the use of sugammadex in patients with this heterogeneous group of diseases and provide recommendations for clinical practice. Methods A systematic electronic search of Medline, Embase and CINAHL databases was done until June 2019, to identify case reports describing the use of sugammadex in adult surgical patients with neuromuscular disorders. Results Of the 578 records identified through database searches, 43 articles were finally included for the systematic review. Of these, 17 reports were on patients with myopathy, 15 reports on myasthenia gravis, 9 reports on motor neuron diseases and 2 reports on neuropathies. Conclusions Majority of the articles reviewed report successful use of sugammadex to reverse steroidal muscle relaxants, especially rocuronium, in patients with neuromuscular diseases. However, with sugammadex, unpredictability in response and uncertainty regarding optimum dose still remain issues. Quantitative neuromuscular monitoring to ensure complete reversal and adequate postoperative monitoring is strongly recommended in these patients, despite the use of sugammadex.

Objective:Review of human cysticercosis in Canada, to estimate the magnitude of the disease and to describe the pattern of disease expression in this country.Methods:MEDLINE and manual search of case reports and case series of patients with cysticercosis diagnosed in Canada. Abstracted data included year of diagnosis, citizenship status, clinical manifestations, and form of cysticercosis.Findings:A total of 21 articles reporting 60 patients were found. Forty (67%) of these patients were diagnosed in the past two decades. Most cases came from Ontario (n=43) and Quebec (n=14). Immigrants accounted for 96% of the 28 cases in whom citizenship information was available. Neurocysticercosis was observed in 55 patients, and isolated compromise of striated muscles in the remaining five. Seizures was the primary or sole manifestation of the disease in 72% of patients, and most of them had parenchymal brain cysticerci (either viable cysts or calcifications). Two of seven patients were positive for Taenia eggs. In no case were household contacts of the patients investigated for taeniasis.Conclusions:An increasing number of patients with cysticercosis have been reported from Canada in the past two decades, suggesting that the prevalence of this parasitic disease may be on the rise. While most cases occur in immigrants, it is possible that at least some of these patients had acquired the disease in Canada.

BACKGROUND፡ This systematic review is conducted to explore available information on clinical presentations, laboratory finding and outcomes of SARS-COV-2 in liver transplant patients.METHODS: We searched four databases for relevant terms related to COVID-19 and liver transplantation and collected both case reports and case series on liver transplantation published up to the end of September 2020.RESULTS: After initial screening of irrelevant articles, 25 studies were included and analyzed in this review. Among the 59 patients included,78.3% were over 50 years old, and 71.6% were males. The majority of patients (93.3%) were hospitalized. The most common presenting symptoms were fever (72.9%) followed by dyspnea and cough (54.2%). The majority of patients revealed a high level of CRP (64.3%). Moreover, high level ALT, AST and ALP were reported in 64.3, 37.5, 30.5 and 22.2% of patients. A total, 9(15.3%), of cases died as a result of complications of COVID-19. Chest radiographs were reported in 72.9%(43/59) of cases that 94% demonstrated radiologic evidence of abnormality.CONCLUSION: The results demonstrated that the most prevalent symptoms and signs were fever, dyspnea and cough. Moreover, most patients were males and hospitalized. The rate of mortality and high level of CRP, ALT/AST and ALP is similar within the non-immune suppressed and general population. However, early detection of high level of serum CRP, ALT/AST and ALP combined with a clinical COVID-19 symptom and finding of CT scan may be used as an index for the presence and severity of the disease.

Abstract Background Existing evidence indicates that the risk of obstetric and perinatal outcomes is higher in women with coronavirus infection. outbreaks suggest that pregnant women and their fetuses are particularly susceptible to poor outcomes. However, there is little known about pregnancy related complications and co-morbidity in this group of women. Therefore, this, systematic review and meta-analysis performed in order to find out whether COVID-19 may cause different manifestations and outcomes in antepartum and postpartum period or not.Methods We searched databases, including Medline (PubMed), Embase, Scopus, Web of sciences, Cochrane library, Ovid and CINHAL to retrieve all articles reporting the prevalence of maternal and neonatal complications, in addition clinical manifestations, in pregnant women with COVID 19 that published with English language from January to April 2020. Results 11 studies with total 177 pregnant women included in this systematic review.Results show that the pooled prevalence of neonatal mortality, lower birth weight, stillbirth, premature birth, and intrauterine fetal distress in women with COVID 19 were 4% (95% Cl: 1 - 9%), 21% (95% Cl: 11 – 31%), 2% (95% Cl: 1 - 6%), 28% (95% Cl: 12 - 44%), and 15% (95% Cl: 4 - 26%); respectively. Also the pooled prevalence of fever, cough, diarrhea and dyspnea were 56% (95% Cl: 30 - 83%), 30% (95% Cl: 21 - 39%), 9% (95% Cl: 2 - 16%), and 3% (95% Cl: 1 - 6%) in the pregnant women with COVID-19.Conclusion According to this systematic review and meta-analysis, the pregnant women with COVID-19 with or without pneumonia, are at a higher risk of pre-eclampsia, preterm birth, miscarriage and cesarean delivery. Furthermore, the risk of LBW and intrauterine fetal distress seems increased in neonates.
