    Purpose Due to its link with the 2019 coronavirus, the multisystem inflammatory syndrome in children (MISC) has garnered considerable international interest. The aim of this study, in which MISC patients were evaluated multicenter, and the data of the third period of the Turk-MISC study group, to compare the clinical and laboratory characteristics and outcomes of MISC patients who did and did not require admission to an intensive care unit (ICU).Methods This retrospective multicenter observational study was carried out between June 11, 2021, and January 01, 2022. The demographics, complaints, laboratory results, system involvements, and outcomes of the patients were documented.Results A total of 601 patients were enrolled; 157 patients (26.1%) required hospitalization in the intensive care unit (ICU). Median age was 8 years (interquartile range (IQR) 4.5-11.3 years. The proportion of Kawasaki disease-like features in the ICU group was significantly higher than in the non-ICU group (56.1% vs. 43.2% p = 0.006). The ICU group had considerably lower counts of both lymphocytes and platelets (lymphocyte count 900 vs. 1280 cells x mu L, platelet count 153 vs. 212 cells x 10(3)/ mu L, all for p< 0.001). C-reactive protein, procalcitonin, and ferritin levels were significantly higher in the ICU group (CRP 164 vs. 129 mg/L, procalcitonin 9.2 vs. 2.2 mu g/L, ferritin 644 vs. 334 mu g/L, all for p< 0.001). Being between ages 5-12 and older than 12 increased the likelihood of hospitalization in the ICU by four [95% confidence intervals (CI)1.971-8.627] and six times (95% CI 2.575-14.654), respectively, compared to being between the ages 0-5. A one-unit increase in log d-dimer (mu g/L) and log troponin (ng/L) was also demonstrated to increase the need for intensive care by 1.8 (95% CI 1.079-3.233) and 1.4 times (95% CI 1.133-1.789), respectively. Conclusion: By comparing this study to our other studies, we found that the median age of MISC patients has been rising. Patients requiring an ICU stay had considerably higher levels of procalcitonin, CRP, and ferritin but significantly lower levels of lymphocyte and thrombocyte. In particular, high levels of procalcitonin in the serum might serve as a valuable laboratory marker for anticipating the need for intensive care.

    Isolated abducens palsy of advanced age: a rare presentation of dural carotid cavernous fistula: a case report
    (African Field Epidemiology Network-Afenet, 2018) Yilmaz, Dilek; Gurses, Asli Akyol; Akkan, Koray; Oner, Yusuf; Ilgit, Erhan; Onal, Baran; Nazliel, Bijen
    Abducens palsy is the most common isolated cranial nerve palsy due to its long peripheral course. Multiple anatomical relationships, particularly within the cavernous sinus and orbita, make the nerve vulnerable. 67 year-old female patient was admitted with worsened headache and lateral gaze restriction of the left eye, which appeared recently. She had no prior history of trauma. Prominent appearance of the left cavernous sinus on cranial magnetic resonance imaging, raised the need of digital substraction angiography which revealed the presence of bilateral type D dural arteriovenous fistula of cavernous sinuses. Cavernous sinus pathologies, which are usually known to manifest with multiple ocular motor palsies because of the close relationship between 3rd, 4th and 6th nerves inside, might rarely present with isolated abducens palsy. The clinician should pay particular attention to headache in such kind of patients and dural carotid-cavernous fistula should be taken into account, even in the absence of previous trauma history.

    A snapshot of pediatric inpatients and outpatients with COVID-19: a point prevalence study from Turkey
    (Springer, 2023) Yilmaz, Dilek; Ustundag, Gulnihan; Buyukcam, Ayse; Sali, Enes; Celik, Umit; Avcu, Gulhadiye; Belet, Nursen
    This multi-center point prevalence study evaluated children who were diagnosed as having coronavirus disease 2019 (COVID19). On February 2nd, 2022, inpatients and outpatients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were included in the study from 12 cities and 24 centers in Turkey. Of 8605 patients on February 2nd, 2022, in participating centers, 706 (8.2%) had COVID-19. The median age of the 706 patients was 92.50 months, 53.4% were female, and 76.7% were inpatients. The three most common symptoms of the patients with COVID-19 were fever (56.6%), cough (41.3%), and fatigue (27.5%). The three most common underlying chronic diseases (UCDs) were asthma (3.4%), neurologic disorders (3.3%), and obesity (2.6%). The SARS-CoV-2-related pneumoniae rate was 10.7%. The COVID-19 vaccination rate was 12.5% in all patients. Among patients aged over 12 years with access to the vaccine given by the Republic of Turkey Ministry of Health, the vaccination rate was 38.7%. Patients with UCDs presented with dyspnea and pneumoniae more frequently than those without UCDs (p < 0.001 for both). The rates of fever, diarrhea, and pneumoniae were higher in patients without COVID-19 vaccinations (p = 0.001, p = 0.012, and p = 0.027). Conclusion: To lessen the effects of the disease, all eligible children should receive the COVID-19 vaccine. The illness may specifically endanger children with UCDs.
