Covid-19 vaccines and neurological complications: a systematic review.

The COVID-19 mainly causes respiratory disorders with high infection and severe morbidity and mortality. Neurologists have concerns about potential neurological side effects, profits, and timing of COVID-19 vaccines. This study aimed to review systematically research for the COVID-19 vaccine and neurological complications. Data was searched in Scopus, ISI web of knowledge, Medline, PubMed, Wiley, Embase, International Clinical Trials Registry Platform and Clinical Trials, Cochrane Library, and Google Scholar. Two reviewer authors individually searched and assessed the titles and abstracts of all articles. The third reviewer resolved disagreement between them. Data were documented regarding study location, study design, type of complications, number of patients, various types of COVID-19 vaccine, and type of neurological complications. Six studies in COVID-19 vaccine and neurological complications include two studies about neurological manifestations after the mRNA vaccines, four records about side effects of vector-based vaccine were included in the study. The main neurological complication associated mRNA vaccines were body aches, paresthesia, and difficulty walking, erythema migrans lesion, fatigue, myalgia, and pain in the left lateral deltoid region. The major neurological complication related to vector-based vaccines were urinary retention difficulty, feeding and ambulating, arm soreness, mild fatigue, chills, left-sided facial droop, headaches, a generalized epileptic seizure, hemianopia, and mild aphasia, acute somnolence and right-hand hemiparesis, acute transverse myelitis, deep vein thrombosis in her left leg, a vigilance disorder and a twitching, a severe immobilizing opsoclonus myoclonus syndrome, and encephalitis. A large spectrum of severe neurological unfavorable has been reported. These complications could occur as a result of molecular stimulation and later neuronal damage. Generally, the advantages of COVID-19 vaccination are dominant on the risks of a neurological complication at both individual and population levels. Future investigations will be required to find any relationship between neurological complications and COVID-19 vaccines principally as new strains of the virus and new vaccines are technologically advanced against them.

Chilblain or perniosis-like skin lesions in children during the COVID-19 pandemic: A systematic review of articles.

COVID toes or chilblain-like skin lesions represent a widespread and specific skin presentation mostly in the feet that may be attributed to COVID-19 infection. They may last for several months. We conducted this study to investigate chilblain-like lesions in children during the COVID-19 pandemic, any predisposition, location, clinical course, and prognosis. We searched Google Scholar, Scopus, and Medline (PubMed) databases using the following keywords: "Coronavirus" OR "COVID-19" AND "Chilblains" OR "Pernio" OR "Perniosis" OR "Children" OR "Cutaneous" OR "skin." The inclusion criteria were: (a) Studies that described the specific vascular skin lesion. (b) Studies that included patients aged >1 month till 18 years. (c) Case reports, case series, retrospective or prospective cohort studies, case-control studies. A total of 28 articles were included. The total number of children with chiblain-like lesions (CLL) was 433. The mean age of children presenting CLL during the COVID-19 pandemic was estimated as 12.58 ± 2.15. Of note, 53.6% of them were male. The nasopharyngeal SARS-CoV-2 RT-PCR test and anti-SARS-CoV-2 antibodies were mostly negative for the virus. In conclusion, it is crucial to be familiar with various presentations of COVID-19 infection and their clinical significance to approach the earliest diagnosis, immediate treatment, estimate the prognosis, and finally isolate the patients to prevent spreading. Chilblain-like lesions as a possible cutaneous presentation of COVID-19 in children may last several months with the indolent course.

Cutaneous manifestations related to the COVID-19 pandemic: a review article.

BACKGROUND: Skin lesions are either caused by COVID-19 disease or they can be due to other driving forces related to the COVID-19 pandemic. AIM: Considering the fact that the reported data in different articles for the type and prevalence of skin manifestations related to the COVID-19 pandemic are inconsistent, we have described the mechanism and type of skin lesions related to the COVID-19 pandemic. METHODS: In this review article, we have searched the Medline database (PubMed) for the combination of the following key terms "Dermatological Manifestation", "cutaneous Manifestation", "Skin Manifestation", "COVID-19", "SARS-CoV-2". RESULTS: The prevalence of skin manifestations related to COVID-19 ranged from 0.2% to 20%. The majority of these skin lesions are maculopapular eruptions. The skin presentations related to the COVID-19 pandemic are described below. Traumatic skin conditions such as dermatitis in individuals, especially those with allergies, might initiate secondary to over-washing or rinsing with inappropriate detergents. Also, inappropriate use of personal protective equipment (mask-gloves-shield) can trigger skin lesions on the face and hands or aggravate the lesions of acne, seborrhoeic dermatitis, eczema, etc. Furthermore, cutaneous adverse drug reactions may occur during hospitalization or outpatient treatment of COVID-19 patients. Also, psychocutaneous disorders due to acute stress can trigger or deteriorate several skin manifestations. Moreover, COVID-19 prevalence and course may be changed in patients with autoimmune or chronic inflammatory underlying skin disorders such as psoriasis, lupus erythematosus, pemphigus, scleroderma who are on immunosuppressive or biological medications to control their disorders. CONCLUSION: Due to the various dimensions of skin organ involvement and the large population affected, long-term skin conditions following this pandemic can be a lot more problematic than it appears. Serious preventive measures and medical supports are necessary to avoid skin disorders from becoming permanent or even chronic.
