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 chilblainlike 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. Chilblainlike lesions as a possible cutaneous presentation of COVID-19 in children may last several months with the indolent course.
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.
Introduction: Botulinum toxin (BTX) type A is now the most often used medicine with an excellent result for upper facial rejuvenation. Case Presentation: This article represents one of the rare adverse effects of the Botulinum toxin type A for cosmetic use in a 50 years-old woman with moderate to severe peri-orbital rhytides. She received four injection of botulinum with six to twelve more interval and 1-day after last injection, she developed mid frontal recurrent episode edema, which spontaneously remitted. Conclusions: Adverse effects of the Botulinum toxin type A for cosmetic use, should be considered before administration.
Background: Pneumomediastinum and pneumothorax are usually rare conditions after pneumonia. This study examines the progress of pneumonia of the coronavirus disease 2019 (COVID-19) to spontaneous pneumothorax and pneumomediastinum in a patient. Case Presentation: The patient was a 40-year-old man who complained of nonproductive cough and dyspnea. He also complained of fever, sore throat, back, and chest pain. The patient used to smoke but now he quit .His O2 saturation was 89% at the time of admission. He was assessed with suspicion of COVID-19. CT scans of the chest showed brief changes of emphysema and a ground glass view was also seen in the lungs. In the patient's tests, RT-PCR testing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was performed and it was positive. Treatment was initiated and because of the progression of symptoms, the serial CT scanning of the patient's lungs was performed daily; and cavitary changes, air-fluid appearance, and destructive changes of lungs were reported. After eight days, the patient's cough worsened. CT scans of the patient's lungs showed some bullaes, pneumothorax, and pneumomediastinum, thus a chest tube was inserted and oxygen therapy was begun on the patient with 3-6 L/min. After 5 days in CT, the patient was relieved of pneumothorax and pneumomediastinum and after a week, the chest tube came out. Conclusion: Pulmonary lesions of COVID 19 can progress to bullae, pneumomediastinum, and pneumothorax. Deterioration of dyspnea and respiratory symptoms can be a warning of pneumomediastinum and pneumothorax that can be confirmed by graphics and timely treatment of the patient can be life-saving.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
