Abstract Introduction: Despite the new SARS-CoV-2 (COVID-19) be the seventh of the coronavirus family viruses known to cause human disease, little is known about potential symptoms and syndromes secondary to the compromise of the central and peripheral nervous systems. We reviewed neurological manifestations due to the new coronavirus, thus far published in the literature, as well as guidelines issued by sub-specialties in Neurology, to tackle the disease. Methods: we searched medical databases, such as PubMed, PubMed Central, LILACS and Google scholar for papers (case reports, short letters, case series, etc) describing neurological symptoms in patients with confirmed or suspect COVID-19 diagnosis and also searched webpages of associations and organizations that deal with neurological disorders. Results: we describe briefly each article considered for this review. Forty-one papers were found associating neurological conditions and COVID-19. Cases are divided by disease groups and, within each disease group, results are listed in chronological order or publication date. We also discuss briefly recommendations for neurological patients, according to disease group. Conclusion: Although there is evidence of neurological manifestations with previous coronaviruses, COVID-19 is assuring a volume of published papers not seen before for other coronavirus infections. Most neurological cases are not life-threatening, but 10 to 20% of cases will require hospitalization and are in risk for sequelae and death. Although a lot of data coming from these papers is amassing, researchers must bear in mind that many papers currently published are not yet peer-reviewed, and thus are prone to further corrections.

AbstractSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus, is responsible for the outbreak of coronavirus disease 19 (COVID-19) and was first identified in Wuhan, China in December 2019. It is evident that the COVID-19 pandemic has become a challenging world issue. Although most COVID-19 patients primarily develop respiratory symptoms, an increasing number of neurological symptoms and manifestations associated with COVID-19 have been observed. In this narrative review, we elaborate on proposed neurotropic mechanisms and various neurological symptoms, manifestations, and complications of COVID-19 reported in the present literature. For this purpose, a review of all current published literature (studies, case reports, case series, reviews, editorials, and other articles) was conducted and neurological sequelae of COVID-19 were summarized. Essential and common neurological symptoms including gustatory and olfactory dysfunctions, myalgia, headache, altered mental status, confusion, delirium, and dizziness are presented separately in sections. Moreover, neurological manifestations and complications that are of great concern such as stroke, cerebral (sinus) venous thrombosis, seizures, meningoencephalitis, Guillain–Barré syndrome, Miller Fisher syndrome, acute myelitis, and posterior reversible encephalopathy syndrome (PRES) are also addressed systematically. Future studies that examine the impact of neurological symptoms and manifestations on the course of the disease are needed to further clarify and assess the link between neurological complications and the clinical outcome of patients with COVID-19. To limit long-term consequences, it is crucial that healthcare professionals can early detect possible neurological symptoms and are well versed in the increasingly common neurological manifestations and complications of COVID-19.

Abstract Background The COVID-19 pandemic has drastically affected everyone in a hit or miss manner. Since it began, evidence of the neuro-invasive potential of the virus has been intensifying significantly. Several pathways have been hypothesized to elucidate the neurotropic nature of SARS-CoV2. It is the need of the hour to collect vital information. Objective To evaluate and correlate the neuro-radiological and neurological manifestations in patients diagnosed with SARS-CoV2. To identify neuro-invasive pathways of COVID infection. Methods Relevant studies were identified through four databases—the Cochrane Library, PubMed, Science Direct, and Web of Science. These were searched using relevant keywords—“COVID-19,” “SARS-CoV2,” “neurological manifestations,” “neuroimaging,” “CT,” and “MRI.” Relevant articles were screened according to a pre-defined inclusion and exclusion criteria from December 2019 to August 2020. Results Our review included a total of 63 full text publications with 584 patients, composed mainly of observational studies, case reports, and case series. The most common neurological manifestations associated with COVID-19 were altered mental status, stroke, and paralysis. About 17.85% patients who underwent neuroimaging were found to be having ischemic changes suggestive of a stroke. This was followed by hemorrhagic changes as the second most common finding. The most commonly involved vessel was the Middle Cerebral Artery. Besides stroke, we found that SARS-CoV2 could be the cause for new-onset seizures, Guillain-Barre Syndrome, encephalitis, and many other severe neurological diseases. Conclusion The information that we have obtained so far will prove dynamic to healthcare providers working against the COVID-19 pandemic. It is necessary to be aware of these atypical neurological findings for the early diagnosis and treatment of COVID-19 infected patients. However, to completely understand the connection between SARS-CoV2 and the nervous system, further research is necessary.

AbstractPatients with COVID-19 present with a myriad of comorbidities. An immunocompromised state like HIV in patients with COVID-19 can be life-threatening. We searched PubMed/Medline, Scopus, and Web of Science for case reports and case series about COVID-19 in HIV patients. We finally reviewed 20 case reports including cases of 43 patients with HIV and COVID-19. The mean age of 43 adult patients was 51.56 ± 27.56 years (range 24–76 years). Of these, 30 were male (69.77%), 11 were female (25.58%), and 2 were transgender (4.65%). A total of 25 patients (58.14%) were above 50 years of age. The most common cardiovascular comorbidities were hypertension and hyperlipidemia (48.8%), diabetes (20.93%), and morbid obesity (11.63%). Out of 43 HIV patients with COVID-19, 6 resulted in death (13.95%). All the patients who died were elderly above 50 years and required mechanical ventilation. HIV patients infected with COVID-19 had a high mortality rate. A high burden of pre-existing comorbidities and an advanced age in these patients make them prone to disease progression and worse outcomes.

Objectives: Yew plant materials contain highly toxic taxine alkaloids. Serious ingestions can result in life-threatening toxicity. The purpose of this article is to summarize the literature on the treatment of acute yew poisoning. Data Sources: PubMed (January 1946 to November 2017) was searched using the search terms “taxus/po”. EMBASE (1980 to November 2017) was searched using the search terms “taxus/to” and “yew.mp.” Web of Science (1945 to November 2017) was searched using the text words taxus, taxine, and yew. Study Selection and Data Extraction: Available English language articles involving case reports, epidemiology, treatment, and outcomes were included. Data Synthesis: Although not uncommon, unintentional yew poisoning rarely results in significant morbidity or mortality. A total of 26 case reports of yew poisoning were evaluated along with 4 case series articles (totaling 22 additional cases). Only 4 of the 48 total cases (8%) were accidental poisonings, the rest being deliberate ingestions. In 20 patients (42%), it resulted in fatalities. Severe, acute yew poisoning results in symptomatology largely resistant to pharmacotherapy intervention. Conclusions: Most nonintentional ingestions of yew plant constituents are asymptomatic and require little intervention. Severe poisoning can result in life-threatening cardiac toxicity and require aggressive supportive care. Therapeutic interventions, such as sodium bicarbonate, digoxin immune fab, and hemodialysis that have been utilized in case studies and case series in the literature have little proven benefit. Extracorporeal life support should be considered in severe yew poisoning.

Spontaneous Haemorrhage

One known medical complication in patients with cirrhosis of the liver is sudden onset gastrointestinal haemorrhage which is usually variceal in nature and can be life threatening [1]. On occasion spontaneous haemorrhage from varices in other locations may also occur [2]. In addition, episodes of either intraabdominal or intrapulmonary haemorrhage are also associated with poor clinical outcomes in cirrhotic patients [3,4]. In comparison relatively, few cases of spontaneous intramuscular haemorrhage in patients with cirrhosis have been reported up to now. This particular clinical entity has been predominantly the subject of sporadic case reports or case series. Apart from one small case series [5], the majority of the cases were summarised in a published review in 2015 [6]. Hence the most recent case report from Mongelli et al published recently in this journal [7], now becomes the 25th case.

Coronaviruses have been associated with many outbreaks in the past and the recent pandemic caused by SARS-CoV-2 has spread around the globe due to its high transmission rate. SARS-CoV-2 has reported to be associated with respiratory and cardiac complications, but recent case series and case reports of COVID-19 patients suggest that it is also associated with neurological manifestations. The most commonly observed neurological manifestation are headache, anomia, ageusia, dizziness, delirium and the complications include Guillain-Barre syndrome (GBS), acute encephalitis, acute myelitis, and cerebrovascular disorders. The pathways leading to neuronal damage are the retrograde neuronal and hematogenous pathway. This paper is aimed to explain the neurological manifestations associated with COVID-19 patients and the possible pathophysiological mechanisms of neuronal invasion.

Coronavirus (SARS-CoV-2) emerged in China in December 2019 and rapidly caused a global health pandemic. Current evidence seems to suggest a possible link with ecosystem disequilibrium and even air pollution. The primary manifestations affect respiratory and circulatory systems, but neurological features are also being reported through case reports and case series. We summarize neurological symptoms and complications associated with COVID-19. We have searched for original articles published in PubMed/Medline, PubMed Central and Google Scholar using the following keywords: “COVID-19”, “Coronavirus”, “pandemic”, “SARS-COV-2”, “neurology”, “neurological”, “complications” and “manifestations”. We found around 1000 publications addressing the issue of neurological conditions associated with COVID-19 infection. Amongst those, headache and dizziness are the most common reported symptoms followed by encephalopathy and delirium, while the most frequent complications are cerebrovascular accidents, Guillain–Barré syndrome, acute transverse myelitis, and acute encephalitis. Specific symptoms affecting the peripheral nervous system such as hyposmia and dysgeusia are the most common manifestations recorded in the selected studies. Interestingly, it was noted that these kinds of neurological symptoms might precede the typical features, such as fever and cough, in COVID patients. Neurological symptoms and complications associated with COVID-19 should be considered as a part of the clinical features of this novel global pandemic.

Background: Mites are among the smallest arthropods that can be seen without magnification, were the use of dermatoscopy is an invaluable tool. They are a cosmopolitan pest, and at the moment more than 250 species have been shown to produce problems for humans and animals alike. These mites are capable of producing a wide array of clinical signs and symptoms, from local to systemic, from mild to severe, as well as transmitting pathogens. This study aimed to provide an update to the clinical impact on human health, the distribution and species involved in the clinical conditions produced by trombiculids through a systematic review.

This study aimed to provide an update to the clinical impact on human health, the distribution and species involved in the clinical conditions produced by trombiculids through a systematic review. Methods: A systematic literature review was conducted in Medline, Lilacs, Redalyc, Scopus, SciELO and Google Scholar, were we use as a threshold of publication date the year 2008. We limited the search strategy to articles published in Portuguese, French, English and Spanish. Eligible studies were case reports and case series that reported outcomes in humans caused by trombiculid bites. Patient-level and study-level information was extracted. Results: The literature search yielded 832 studies; 13 were case reports, 4 case series and 2 descriptive studies reporting a total of 49 cases. Most patients were male, and the median age was 33.7±6.4 years old. The most frequently reported symptoms were local erythema, pruritus and papules. No deaths were documented. Trombiculids from the genera Trombicula, Eutrombicula and Leptotrombidium appear to be the most commonly reported. Discussion: Trombiculiasis is an infestation caused by the larval stage of various types of mites, known as chiggers, they belong to the class Arachnida and the family Trombiculidae. This systematic review provides an overview of the trombiculids of clinical importance, their distribution and effects of the bite on human health. Our results show that there are different species of mites that can have important consequences for human health. No fatal cases owere registered.Even so, the transmission of scrub typhus is important and remains one of the most life-threatening rickettsial infections in some regions of Asia. Conclusions: The bite of different species of trombiculids around the world can cause a wide array of clinical consequences to human health. Even as mortality appear to be nonexistent, trombiculid bites must be adequately diagnosed and treated properly: A systematic literature review was conducted in Medline, Lilacs, Redalyc, Scopus, SciELO and Google Scholar, were we use as a threshold of publication date the year 2008.

ABSTRACT Objective: To describe clinical features and possible diagnostic criteria of the 50 bath-related headache (BRH) cases that have been published in the literature to date. Methods: Based on a literature search in the major medical databases, we analyzed all case reports or case series on BRH that were published between 2000 and 2017. Results: We describe 48 women and two men diagnosed with BRH. Of these 50 patients, 90% were from Asian countries. The average age was 49.3 years. There was an association of BRH with migraine (28%), tension-type headache (12%) and cold stimulus headache (4%). Headache was bilaterally localized, had an explosive or pulsating quality and a severe intensity. The pain lasted from five minutes to four days. Associated manifestations were nausea, vomiting, photophobia or phonophobia. There was a good therapeutic response with nimodipine and when avoiding a hot bath. Conclusions: Bath-related headache is a benign headache that is not associated with a structural lesion.
