One of these conditions is the Reversible Splenial Lesion (RESLES) syndrome in which the callosum collosum splenium (CSS) is transiently affected. In this article, transient short-term visual impairment a transient splenial lesion due to an epileptic seizure presenting with discussion of other diseases that may cause RESLES based on the case is intended. Case: A twenty-six-year-old female patient admitted to the emergency department with the complaint of blurred vision/sightlessness in both eyes, which started in the morning and repeated 20-30 times, lasting for 5-6 seconds. In histroy, it was learned that she was on the twenty-fifth postpartum day and had a cesarean section with epidural anesthesia, and she did not use medication. Her medical and family history were unremarkable. In vital signs; blood pressure: 110/75 mmHg, pulse: 82 beats/min, respiratory rate: 14/min, fever: 36.5°C. Ophthalmological and neurological examination was normal when she had no visual complaints. Blood tests were normal. Brain tomography was normal. Diffusion MRI revealed a hyperintense lesion in B1000 in CKS and hypointense lesion in ADC. Contrast-enhanced carotid vertebral artery cranial CT angiography was performed in terms of dissection, and it was found to be normal. Electroencephalography performed for the etiology of epileptic seizures, slow waves lasting 4-5 seconds were observed at paroxysmal, generalized theta frequency. With the diagnosis of epileptic seizure, the patient was started on 1000 mg/day maintenance treatment after 1000 mg/day levetiracetam loading. The patient's complaints improved after antiepileptic treatment and did not recur. Conlusion: RESLES is a benign and temporary condition that can be encountered with many etiological reasons. It can happen even in a single epileptic seizure and can mimic many clinical cases. In order to ensure the patient reaches the right treatment without losing time, it is important to know and keep in mind the pre-diagnosis of RESLES in patients with a similar clinic, after excluding other emergency diagnosis. Considering that our case has a demonstrative aspect, it was deemed worthy to be presented.

Its frequency varies according to age. While the incidence of acute symptomatic seizures is 30-39/100 000, it is seen most frequently before the age of 20 and after the age of 60 with the second frequency. Causes such as metabolic disorders, head trauma, and cerebrovascular disease may cause an acute symptomatic seizure. In inactivated coronavirus disease 2019 vaccines, side effects may develop due to inflammation of body cells against given foreign substances. In order to raise awareness, we presented our advanced age case who presented with epileptic seizure after the coronavirus disease 2019 vaccine. A 72-year-old female patient was brought to the emergency room because of convulsions and wheezing after fainting. It was learned that she had urinary incontinence and foaming at the mouth during contraction. She had a history of diabetes and hypertension. She had no previous history of epileptic seizures. It was learned she had a third dose of coronavirus disease 2019 vaccine 3 days ago. There was no feature in her family history. Her vitals, physical, and neurological examinations were normal. Blood tests, cardiac examinations, neuroimaging, and cerebrospinal fluid analysis were normal. Once an epileptic seizure was observed in the follow-up, antiepileptic therapy was started. The patient whose seizure did not recur was discharged.

Venöz anomalilerin en sık görülen şekli serebral vasküler malformasyonlardır. Genellikle bilgisayarlı tomografi (BT) veya manyetik rezonans görüntüleme (MRG) taramalarında insidental saptanırlar. Bunun yanısıra hemoraji, iskemik inme, epileptik nöbet veya baş ağrısı ile klinik pratikte karşımıza çıkabilir. Bu çalışmada serabral venöz anomalilerin nadir bir epileptik nöbet nedeni olabileceğinin vurgulanması amaçlanmıştır. Olgu: Daha önce epilepsi ve başka hastalık öyküsü olmayan 24 yaşında erkek hasta jeneralize tonik klonik nöbete benzer şekilde dört ekstermitede birden olan kasılma ve bilinç kaybı ile acil servise getirildi. İki dakika süren tüm vücutta kasılma, idrar inkontinansı, ağızda köpürme ve çenede kitlenme olduğu ve 1 saat boyunca bilincinin kapalı kaldığı öğrenildi. Özgeçmiş ve soygeçmişinde özellik yoktu.

Methods: The prospective study was conducted from April 2014 to April 2015 at the emergency department of Marmara University Pendik Research and Training Hospital,Turkey, and comprised community-acquired pneumonia patients diagnosed according to the British Thoracic Society criteria. Prognosis was estimated using confusion, urea, respiratory rate, blood pressure and age ?65, Pneumonia Severity Index-Pneumonia Patient Outcome Research Team score, and severe community-acquired pneumonia scores. Data was analysed using MedCalc 15.8. Results: Of the 203 patients assessed, community-acquired pneumonia was confirmed in 152(74.8%). Procalcitonin had moderate correlation with the three scales used (p<0.001), while C-reactive protein had weak correlation with them (p<0.004). Conclusion: B...

Symptoms and signs can be produced by rupture or the occlusion of a major vessel. We present a case of aortic dissection that presented to the emergency department with neurovascular symptoms. Case Report: A 55-year-old woman was admitted to our emergency department because of a sudden inability to walk and severe leg pain. She had known hypertension. Her distal pulses were weak, and the legs were cold and pale. She had motor deficits in the lower extremities, too. Her computed tomography revealed aortic dissection from the root of the aorta to the common iliac arteries. Results: Presentation of aortic dissection with neurovascular manifestations is not so common. Despite significant advances in diagnostic and therapeutic techniques, morbidity and mortality rates remain high. So, a high clinical index of suspicion and early diagnosis are necessary.

Hastada ateş, rijidite, konfüzyon, solunum sıkıntısı görülebilecek önemli semptomlardır. Özellikle 2019-2020 yılında ortaya çıkan ve önemli bir belirtisi de düşmeyen ateş yüksekliği olan Covid-19 hastalığından sonra ateş yüksekliği ile başvuran, anamnezi uygun olan hastaların ayırıcı tanısında akılda bulundurulması gereken bir hastalık olduğu konusunda farkındalığın olması önemlidir. Bu amaçlardan yola çıkarak bu olgunun sunumunun yararlı olacağını düşünmekteyiz.
