Oral Manifestations of COVID-19 in Hospitalized Patients: A Systematic Review

Background: COVID-19 disease first appeared in 2019 and quickly spread worldwide, causing a global pandemic. The oral cavity represents a target of SARS-CoV-2, and oral lesions are observed in both non-hospitalized and hospitalized patients. This systematic review aims to investigate the frequency of oral manifestations in COVID-19 hospitalized patients. Methods: An electronic search was conducted in PubMed, Scopus, and Web of Science databases, including articles published up to September 2021. The review protocol was based on PRISMA-P. The risk of bias of the studies was assessed using the Joana Briggs Institute. The certainty of evidence was assessed using the GRADE instrument. Results: Fifty-nine articles were included: 19 case reports, 17 case series, 2 case-control studies, 13 cross-sectional studies, 4 observational studies, and 4 retrospective studies. Oral ulcers, cheilitis, and tongue lesions were more common in patients before hospitalization, while perioral pressure ulcers, macroglossia, blisters, and oral candidiasis were more recurrent in patients during hospitalization. The first could be related directly to COVID-19, while the latter could be caused by medical devices, treatments, prone position, and immunological impairment. Conclusions: An accurate oral examination during the hospital admission of all confirmed COVID-19 cases is encouraged to recognize oral early manifestations and to apply appropriate treatments.

Abstract Background Neglected tropical diseases (NTDs) affect more than one billion people living in vulnerable conditions. In spite of initiatives recently contributing to fill NTDs gaps on national and local prevalence and distribution, more epidemiological data are still needed for effective control and elimination interventions. Main text Mozambique is considered one of the countries with highest NTDs burden although available data is scarce. This study aims to conduct a systematic review on published available data about the burden and distribution of the different NTDs across Mozambique since January 1950 until December 2018. We identified manuscripts from electronic databases (Pubmed, EmBase and Global Health) and paper publications and grey literature from Mozambique Ministry of Health. Manuscripts fulfilling inclusion criteria were: cross-sectional studies, ecological studies, cohorts, reports, systematic reviews, and narrative reviews capturing epidemiological information of endemic NTDs in Mozambique. Case-control studies, letters to editor, case reports and case series of imported cases were excluded. A total of 466 manuscripts were initially identified and 98 were finally included after the revision following PRISMA guidelines. Eleven NTDs were reported in Mozambique during the study span. Northern provinces (Nampula, Cabo Delgado, Niassa, Tete and Zambezia) and Maputo province had the higher number of NTDs detected. Every disease had their own report profile: while schistosomiasis have been continuously reported since 1952 until nowadays, onchocerciasis and cysticercosis last available data is from 2007 and Echinococcosis have never been evaluated in the country. Thus, both space and time gaps on NTDs epidemiology have been identified. Conclusions This review assembles NTDs burden and distribution in Mozambique. Thus, contributes to the understanding of NTDs epidemiology in Mozambique and highlights knowledge gaps. Hence, the study provides key elements to progress towards the control and interruption of transmission of these diseases in the country.

Background: The Coronavirus disease 2019 (COVID-19) outbreak has put a great burden on global health and healthcare systems. There is controversy regarding the possibility of vertical transmission of COVID-19. This proposed systematic review will be done to assess the possibility of vertical transmission of COVID-19 based on currently published literature. Methods: In this study, all published observational studies, including cross-sectional, cohort, and case-control studies, as well as case reports and case series, in peer-reviewed journals in any language until the end of July 2020 will be assessed. Editorials, commentaries, and letters to editors will be excluded from the review. Searching will be conducted using international bibliographic databases, including PubMed, Embase, and Web of Science based on Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) checklist. The search strategy will be improved and finalized based on the results of the primary search. Data extraction of the included articles will be performed by two researchers using the Zotero and review manager (revMan) software. The heterogeneity of the articles will be assessed using DerSimonian & Laird Q test and I2 statistic. The pooled estimated prevalence of vertical transmission of COVID-19 will be performed using the Metaprop command. Publication bias will be assessed using Begg’s rank correlation and the Egger weighted regression methods Results: Based on the reviewers comments the results section was deleted because this manuscript was a systematic review protocol. Conclusion: The findings of this study will help practitioners and health care providers in decision-making for the care and management of COVID-19-infected pregnant women.

Introduction: COVID-19 (coronavirus disease 2019) was identified in China in December 2019 for the first time and is rapidly spreading throughout the world as a pandemic. As COVID-19 causes mild to severe acute respiratory syndrome, most studies in this context have focused on pathogenesis primarily in the respiratory system. However, evidence shows that the central nervous system (CNS) may also be affected by COVID-19. Since COVID-19 is spreading, it is imperative to study its possible cognitive effects in patients suffering and recovering from COVID-19. Methods: The articles used in this study were searched by keywords such as Cytokine storm and covid-19, covid-19 and executive dysfunction, cognitive disorder and covid-19, CNS and covid 19, Coronavirus, Neuroinvasion in science direct, Scopus, PubMed, Embase, and Web of Science databases based on Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) checklist. The study will assess all observational studies published between December 2019 and April 2021 in peer-reviewed journals, including cross-sectional, cohort, case-control studies, case reports and case series. The search result was 106 articles, of which 73 articles related to Covid-19, the stages of infection by this virus, its effect on the nervous system and neurological symptoms, the cytokine storm caused by this infection, and the possible cognitive consequences caused by this virus in patients, has been reviewed. Other articles were not checked due to their limited relevance to the topic under discussion. Results: Studies show that neurons may be directly affected by SARS-CoV-1 and SARS-CoV-2. Furthermore, various studies indicate that systemic inflammation (so-called "cytokine storm") is also responsible for brain damage induced by infection with SARS-CoV-1 and SARS-CoV-2. Such a way that this patients showed elevated levels of interleukin (IL-), 6, 8, and 10 and of tumor necrosis factor-alpha (TNF- α) in their blood. Conclusion: Various cognitive defects following an increase level of cytokines such as TNF-α and IL-6,8 have been observed. Therefore, due to the increase level of these pro-inflammatory factors in the brains of these patients, cognitive deficits can be expected, which need further investigation.

Nicotine Administration

Abstract Background Preliminary studies have tested nicotine as a novel treatment for OCD patients who respond partially/incompletely or not at all to first and second-line treatment strategies, with the former represented by SSRIs or clomipramine, and the latter by switching to another SSRI, or augmentation with atypical antipsychotics, and/or combination with/switching to cognitive–behavioural therapy. Some studies found nicotine-induced reduction of obsessive thoughts and/or compulsive behaviour in OCD patients. We aimed to evaluate the efficacy of nicotine administration in OCD patients. Methods We searched the PubMed, ScienceDirect Scopus, CINHAL, Cochrane, PsycINFO/PsycARTICLES, and EMBASE databases from inception to the present for relevant papers. The ‘Preferred Reporting Items for Systematic Review and Meta-Analyses’ (PRISMA) standards were used. We included all studies focusing on the effects of nicotine administration on OCD patients’ obsessions or compulsions. Studies could be open-label, cross-sectional, randomized controlled trials, case series or case reports. Results A total of five studies could be included. Nicotine administration may ameliorate behavioural features and recurrent thoughts of severe, treatment-resistant OCD patients; however, in one study it was not associated with OC symptom improvement or cognitive enhancement across various executive function subdomains. Conclusions Although encouraging, the initial positive response from the use of nicotine in OCD needs testing in large controlled studies. This, however, raises ethical issues related to nicotine administration, due to its addiction potential, which were not addressed in the limited literature we examined. As an alternative, novel treatments with drugs able to mimic only the positive effects of nicotine could be implemented.

Gonococcal Urethritis ◽

Clinical Complications

Background: It is estimated that between 50 and 89% of non-gonococcal urethritis is not caused by Chlamydia trachomatis. Associations between non-chlamydial non-gonococcal urethritis (NCNGU) with balanoposthitis, epididymo-orchitis and reactive arthritis have been suggested, but evidence to support these often-theoretical relationships is sparse and further investigation is called for. Concerns over increasing antimicrobial resistance has rendered the need for clarity over this question ever more pressing in recent years. A review of the current evidence on the complications of NCNGU in men is therefore urgently warranted. Objective: This systematic review summarizes and evaluates the available evidence that NCNGU, whether symptomatic or asymptomatic, causes the significant complications that are already well-recognized to be associated with non-gonococcal urethritis. These significant complications are epididymo-orchitis, balanoposthitis, and sexually-acquired reactive arthritis (Reiter's syndrome) including arthritis or conjunctivitis. Summary: We conducted a systematic review and qualitative synthesis using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis framework. Five databases (PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, and British Nursing Index) were searched. We included studies that measured clinical outcome after diagnosis of NCNGU in men. Bias was assessed using variations of the Newcastle-Ottawa scale. Data were extracted and entered into a pre-written data abstraction proforma. Seven peer-review studies were included. This included 2 retrospective cohort studies, 1 case series, 2 case reports and 2 cross-sectional studies. The studies described and analyzed 3 types of complication: balanitis, posthitis and/or meatitis; reactive arthritis and/or conjunctivitis; and epididymitis. All studies reported one or more complications. Key Messages: This review identifies an important avenue for future research: while the available evidence suggests that NCNGU has the potential to cause significant complications in men, with the strongest evidence existing for balanitis, posthitis and/or meatitis, the nature and significance of these relationships is far from clear. The findings of this review suggest that prospective, adequately powered research into whether there is a causal link between NCNGU and significant clinical complications in men would be highly worthwhile. The findings of this review raise important questions about the utility of the term NCNGU in research and clinical practice.

Seborrheic Keratoses

Background Eruptive seborrheic keratoses (ESK) is a benign skin condition that has been associated with malignant and nonmalignant diseases. We conducted a systematic review of reported cases of ESK to identify and summarize associated comorbidities. Methods MEDLINE and Embase were searched from database inception (1946) to July 31, 2020 for original articles describing ESK with or without a co-occurring condition. Subject demographics, as well as details of ESK and associated diagnoses were extracted from 76 articles (70 case reports, 3 case series, 3 case control studies) representing 92 patients. Results In total, 76.1% ( n = 70/92) of patients with ESK had a co-occurring malignancy, 4.3% ( n = 4/92) presented with a nonmalignant condition, 9.8% ( n = 9/92) experienced ESK as an adverse drug reaction, and 9.8% ( n = 9/92) did not report any underlying medical condition. ESK preceded a cancer diagnosis in 76.1% ( n = 70/92) of patients with a mean latency period of 4.0 months (range: 0.25-9 months). The most common malignancies associated with ESK were cutaneous T-cell lymphoma ( n = 10/70, 14.3%) and gastrointestinal adenocarcinoma ( n = 9/70, 12.9%). ESK preceded nonmalignant conditions or no disease in 14.1% ( n = 13/92) of patients with a mean latency period of 3.1 months (range: 0.75-6 months). Drug-induced ESK occurred in 9.8% ( n = 9/92) of patients with a mean latency period of 7.1 weeks after changing medication. Conclusion Although the role of ESK as a paraneoplastic cutaneous marker is debated, healthcare providers should consider screening for underlying malignancy in patients presenting with ESK. Larger studies are needed to confirm its role as a marker for disease.

Adverse Pregnancy

Pregnant women are susceptible to viral infections due to physiological changes such as cell-mediated immunity. No severe adverse pregnancy or neonatal outcomes have been consistently reported in COVID-19 positive pregnancy cases. There are controversies around the role of COVID-19 in pregnancy. A systematic review was conducted to examine clinical maternal and neonatal clinical outcomes. Studies were included if they reported COVID-19 infection among pregnant women and/or COVID-19 positive neonates as validated by positive antibody testing or viral testing using Polymerase Chain Reaction. Case series, case reports, case-control studies, and comparative studies were included. 837 records were identified, resulting in 525 records for level I screening. 41 were included after full-text review. Results suggest elevated rates of ICU admission, gestational diabetes, preeclampsia, C-sections, pre-term birth, and CRP in comparison to pregnant women without SARS-CoV-2. Careful monitoring of pregnancies with SARS-CoV-2 to minimize adverse clinical outcomes is recommended.

The Mean

Abstract Megaesophagus progress to sigmoid megaesophagus (SM) in 10–15% of patients, presenting tortuosity and sigmoid colon aspect. Esophagectomy is the choice treatment but is associated with high complications and mortality rates. To avoid the esophagectomy inherent morbidity, several authors recommend Heller myotomy (HM) with pull-down technique for SM, mainly for patients with comorbidities and the elderly. This systematic review and meta-analysis is the first to analyze the effectiveness of HM for treating SM. Methods A systematic review was conducted in PubMed, Embase, Cochrane Library Central, Lilacs (BVS), and manual search of references. Inclusion criteria were: a) clinical trials, cohort studies, case series; b) patients with SM and esophageal diameter ≥ 6 cm; and c) patients undergoing primary myotomy. The exclusion criteria were: a) reviews, case reports, cross-sectional studies, editorials, letters, congress abstracts, full-text unavailability; b) animal studies, c) previous surgical treatment for achalasia; and d) pediatric studies. There were no restrictions on language or date of publication, and no filters were applied for the selection process. Random model and a 95% confidence interval (CI) were used. Results Sixteen articles were selected, encompassing 231 patients. The mean age ranged from 36 to 61 years old, and the mean follow-up ranged from 16 to 109 months. The analyzed outcomes include mortality, complications (pneumonia, pneumothorax, gastroesophageal reflux), need for reintervention (remyotomy, dilation and esophagectomy), and results classified as ‘good’ and ‘excellent’. Mortality rate was 0.035 (CI: 0.017–0.07; p < 0.01). Complications rate was 0.08 (CI: 0.04–0.153; p = 0.01). Need for retreatment rate was 0.161 (CI: 0.053–0.399; p < 0.01). Probability of good or excellent outcomes after myotomy was 0.762 (CI: 0.693–0.819; p < 0,01). Conclusion Heller myotomy is an option for avoiding esophagectomy in achalasia, with a low morbimortality rate and good results. It is effective for most patients but will fail in a minority of patients and demand retreatment, be it a remyotomy, endoscopic treatment or esophagectomy.
