In many studies, varying degrees of liver damage have been reported in more than half of the COVID-19 patients. The aim of this study is to determine the effect of liver biochemical parameters abnormality on mortality in critical COVID-19 patients who have been followed in the ICU since the beginning of the pandemic process. In this study 533 critical patients who admitted to the ICU due to COVID-19 were included. The patients were divided into three groups according to their ALT, AST, and total bilirubin levels at their admission to the ICU. Group 1 was formed of patients with normal liver biochemical parameters values; Group 2 was formed of patients with liver biochemical parameters abnormality; Group 3 was formed of patients with liver injury. 353 (66.2%) of all patients died. Neutrophil, aPTT, CRP, LDH, CK, ALT, AST, bilirubin, procalcitonin and ferritin values in Group 2 and Group 3 were found to be statistically significantly higher than Group 1. It was detected that the days of stay in ICU of the patients in Group 1 was statistically significantly longer than others group. It was found that the patients in Groups 2 and 3 had higher total, 7-day, and 28-day mortality rates than expected. The study showed that liver disfunction was associated with higher mortality and shorter ICU occupation time.

Amaç: Bu çalışmada; gebelerde, Toxoplasma gondii, Rubella virüs ve Cytomegalovirus infeksiyonlarının bölgemizdeki seroprevalanslarının belirlemesi amaçlanmıştır. Yöntemler: Bu çalışmada hastanemize Eylül 2016 ile Haziran 2018 tarihleri arasında kadın hastalıkları ve doğum polikliniklerine ilk prenatal vizite gelen 18-45 yaş arası gebeler dahil edildi. Bu hastalardan Toxoplasma gondii, Rubella ve Cytomegalovirus virüs serolojisi çalışılanların test sonuçları retrospektif olarak incelendi. Bulgular: Toxoplasma gondii antikorları açısından 8175 hastanın 2853’ inde (%34,9) anti toksoplazma gondii IgG antikorları, 91’ inde (%1,1) anti Toxoplasma gondii IgM antikorları pozitif olarak saptandı. Cytomegalovirus antikorları açısından 2797 hastanın 2775’ inde (%99,2) anti Cytomegalovirus IgG, 20’ sinde (%0,7) anti Cytomegalovirus IgM pozitif olarak saptandı.Rubella virüs antikorları açısından 8158 hastanın 7677’ sinde (%94,1) anti Rubellavirus IgG, 5’ inde (%0,1) anti Rubellavirus IgM pozitif olarak saptandı. Sonuç: Bu çalışmada hastanemize başvuran gebelerin çoğunun toksoplazma seronegatif (%65,1) olduğu tespit edildi.Rubella seroprevalansı (%94,1) Türkiye verileri ile uyumludur. Gebelerin Cytomegalovirus seroprevalansı için seropozitiflik oranı (%99,2) dünya verileri ile uyumludur.

Purpose: In this study, we evaluated the hypothesis that preoperative bilateral infraoptic nerve (ION) and infratrochlear nerve (ITN) blocks under general anesthesia with sevoflurane and remifentanil reduced the incidence of emergence agitation (EA), pain scores, and the analgesic consumption after the septorhinoplasty. Patients and Methods: Our study was conducted as a prospective randomized, double-sided blind study. Fifty-two patients whose septorhinoplasty operation was planned under general anesthesia were included in the study. Patients were randomly distributed to either the ION and ITN blocks were performed. Group 1: Bilateral ION and ITN blocks were performed; Group 2: ION and ITN blocks were not performed. Duration of the surgery and anesthesia, Riker Sedation-Agitation Scale (RSAS) score, EA presence, duration of postoperative analgesia, numerical rating scale (NRS) scores, and cumulative dexketoprofen consumption were recorded. Results: The RSAS score, NRS score and cumulative dexketoprofen consumption of the patients in Group 1 were statistically significantly lower than the patients in Group 2 (p< 0.05). It was also found that patients in Group 1 (n: 8/26) had less EA compared to patients in Group 2 (n: 16/26) and this difference was statistically significant (p: 0.026). Postoperative analgesia duration of patients in Group 1 was found to be statistically significantly higher than patients in Group 2 (p: < 0.001). In addition, the number of patients given postoperative dexketoprofen in Group 1 (n: 8/26) was found to be statistically significantly lower than patients in Group 2 (n: 25/26). (p: < 0.001). Conclusion: Bilateral ION and ITN blocks in septorhinoplasty operation is an effective, reliable and simple technique in the treatment of postoperative pain.

Over the years, many cultures have used herbs for serious health problems. Garlic (Allium sativum) pose hypocholesterolemic, fibrinolytic, antidiabetic, and antibiotic actions. However, it has unusual adverse effects such as chemical burns and contact dermatitis when used topically. In this case report, the authors present two cases of topical garlic burn caused after the use of crushed garlic with a bandage for pain relief due to arthritis.

Amaç: Bu çalışmada yoğun bakım ünitesinde (YBÜ) yatan kritik koronavirüs hastalığı-2019 (COVID-19) hastalarını demografik, klinik ve laboratuvar özellikleri açısından karşılaştırıp mortaliteye etkili olan faktörleri saptamayı amaçladık. Gereç ve Yöntem: Çalışmaya YBÜ’de COVID-19 nedeniyle yatan 445 hasta dahil edildi. Hastalar YBÜ’de takipleri sırasında mortalite gelişmeyenler ve mortalite gelişenler olarak iki gruba ayrılıp demografik, klinik ve laboratuvar özellikleri açısından karşılaştırıldı ve mortaliteye etki eden faktörler saptanmaya çalışıldı. Bulgular: İleri yaş, YBÜ’ye ilk yatıştaki yüksek Böbrek Hastalıkları: Küresel Sonuçların İyileştirilmesi (KDIGO) evresi ve Sıralı Organ Yetmezliği Değerlendirmesi (SOFA) skorları, yüksek nötrofil lenfosit oranı, yüksek D-dimer düzeyleri düşük bikarbonat (HCO3) değerleri, yüksek laktat dehidrogenaz (LDH) düzeyleri ve yüksek kreatinin düzeyleri YBÜ’de yatan kritik COVID-19 hastalarında mortalite için bağımsız risk faktörleri olarak saptandı. Özellikle YBÜ’ye başvuru esnasındaki KDIGO evresiyle mortalite arasındaki ilişki dikkat çekiciydi. Sonuç: YBÜ’de yatan kritik COVID-19 hastalarında yaş, ilk yatıştaki KDIGO ve SOFA skorları, nötrofil lenfosit oranı, D-dimer, HCO3, LDH ve kreatinin mortalite için bağımsız risk faktörleridir.

Background/Objectives: This study aimed to investigate the effects of explaining the perioperative process to pediatric patients scheduled for adenotonsillectomy using pictures on their anxiety levels. Methods: A prospective, randomized controlled trial was conducted, enrolling 58 patients. The patients were divided into two groups: Group 1 (n = 29), where the perioperative process was explained using pictures, and Group 2 (n = 29), the control group, where no pictures were used. Child anxiety was assessed using the modified Yale Preoperative Anxiety Scale Short Form (mYPAS-SF) at five observation time points before anesthesia induction. Parents’ anxiety was measured using the Visual Analog Scale for Anxiety. Results: Patients in Group 1 had significantly lower heart rates during induction and the intraoperative period compared to Group 2 (p = 0.031, p = 0.025, respectively). In terms of anxiety and RSAS scores, patients in Group 1 had significantly lower mYPAS-SF scores at time points t2, t3, t4, and t5 compared to Group 2 (t2: p = 0.001; t3–t5: p < 0.001). No significant difference was observed at t1 (p = 0.068). The mean RSAS scores were also significantly lower in Group 1 (p = 0.029). Parents’ anxiety was significantly lower in Group 1 at all three time points (t1: p = 0.017; t2: p = 0.006; t3: p = 0.036). Conclusions: Our study results demonstrate that illustrating the perioperative process to children undergoing adenotonsillectomy can significantly reduce preoperative anxiety and prevent awakening agitation. Given its ease of implementation, we believe that using visual aids to explain the perioperative process to pediatric patients can facilitate process management for patients, parents, and physicians.
