Item A Case of Transient Visual Field Defect following Administration of Pfizer-BioNTech COVID-19 Vaccine(2022) Sezenoz, Almila Sarigul; Gungor, Sirel Gur; Kibaroglu, Seda; https://orcid.org/0000-0002-7030-5454; https://orcid.org/0000-0001-6178-8362; https://orcid.org/0000-0002-3964-268X; 35404749; AAJ-4860-2021; AAD-5967-2021; AAJ-2956-2021Purpose To report a case of transient visual field (VF) defect after coronavirus disease-19 (COVID-19) vaccination. Case Report A 38-year-old Caucasian, otherwise healthy female patient, presented with a complaint of vision loss in the outer quadrant in her left eye after the second dose of Pfizer (R)-BioNTech (TM) COVID-19 vaccine. The Snellen visual acuity was 20/20 in both eyes. She did not have relative afferent pupillary defect nor disturbance of color vision. Her intraocular pressures, slit lamp and fundus examinations were normal. In the VF test, a temporal hemifield defect in the left eye and a nasal peripheral VF defect in the right eye were detected. Other imaging characteristics and neurological examination were normal. She was followed without any treatment. One week later, the patient was re-evaluated and complete resolution of the VF defect was observed. Conclusion Clinicians should be aware that patients can experience transient visual symptoms following COVID-19 vaccination.Item Hepatitis A susceptibility parallels high COVID-19 mortality(2021) Sarialioglu, Faik; Belen, Fatma Burcu; Hayran, Kadir Mutlu; 0000-0002-8257-810X; 0000-0002-9278-6703; 32718125; AAL-7766-2021Background/aim: COVID-19 has become the biggest health problem of this century. It has been hypothesized that immunity against hepatitis A virus (HAV) may provide protection from COVID19. Materials and methods: As of 10 June 2020, the infection had spread to 213 countries, with 7.3 million people infected and 413,733 dead. This data was combined with the World Health Organization susceptibility classification on the worldwide prevalence of HAV, and the relationship between HAV susceptibility and COVID-19 mortality were analyzed. Results: When the data from 213 countries were analyzed, it was found that there was a significant increasing trend in COVID-19 mortality rates by HAV susceptibility (P <0.001). Using a cut-off of 200/million population, the mortality risk associated with living in a more susceptible country (medium/high) was 27.8 times higher (95% CI for OR: 3.6-213.2) Conclusion: The results of this study showed that, despite confounding factors in different countries, hepatitis A susceptibility of the population may have been correlated with COVID-19 mortality. This observation needs to be confirmed by further studies.Item May rotavirus vaccine be affect food allergy prevalence?(2020) Karakas, Nazmi Mutlu; Arslan, Almina; Atalay, Ece; Ayli, Itir; Bagci, Zeynep Ilayda; Cesaretli, Sude; Koksal, Burcu Tahire; Yilmaz Ozbek, Ozlem; 0000-0002-2388-4158; 0000-0003-4286-7086; 0000-0001-9580-7656; 32530362; AAJ-7580-2021; AAX-3831-2020; AAF-2109-2021Incidence of food allergy (FA) during nursing period is 6-8% globally and It is reported %5,7 in Turkey. In our study, the aim is to determine whether the prevalence of food allergy (FA) increases in children vaccinated against rotavirus. The files of 681 infants who are still followed-up were retrospectively evaluated. Children who did not come to our clinic for all of their well-child follow-up visits were excluded from the study. Moreover, children diagnosed with allergy before vaccination and children with known gastrointestinal system disease were excluded from the study. The number of patients diagnosed with food allergy after being vaccinated against rotavirus was 12 (1.76%). Three children had a family history of allergy. Of 12 patients who were diagnosed after vaccination, 3 (n:104) were vaccinated with pentavalent vaccine and 9 (n:507) with monovalent vaccine. In the monovalent vaccination group, food allergy was found in 9 children (1.55%), and in the pentavalent vaccination group, food allergy was found in 3 children (2.88%). The difference between the two vaccination groups in terms of food allergy prevalence was not significant (p> .05). Although it is believed that food allergy, and even cow's milk protein allergy (CMPA) prevalence increases in infants vaccinated against rotavirus, in this study, no significant increase was observed in the prevalence of food allergy after rotavirus vaccination. Both types of vaccine had similar rates to each other.
