Introduction and Objectives 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. Materials and Methods 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. Results 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. Conclusions The study showed that liver disfunction was associated with higher mortality and shorter ICU occupation time.

Background and PurposeVitamin A is depleted during infections. Vitamin A has been used successfully in measles, RSV and AIDS patients and is an effective vaccine adjuvant. In this study, low retinol levels were found in patients with severe COVID-19. Retinoid signaling impairment in COVID-19 disrupts Type-I interferon synthesis.Material and MethodTwo groups were formed in the study. The patient group consisted of 27 (Group 1) severe COVID-19 patients hospitalized in the intensive care unit with respiratory failure, and the control group consisted of 23 (Group 2) patients without COVID-19 symptoms. Serum retinol levels were analyzed by ELIZA and HPLC in both groups.FindingsRetinol levels were found to be significantly lower in the patient group (P <0.001). There was no difference in retinol between two different age groups in the patient group (P> 0.05). There was no significant difference in retinol between men and women (P> 0.05). Comorbidity did not affect serum retinol levels (P >0.05).ConclusionSerum retinol levels were low in patients with severe COVID-19. Drugs preventing retinol excretion were not stopped in the patient group. Some patients took vitamin A externally. Despite this, retinol was low in COVID-19 patients. Retinol depletion impairs Type-I interferon synthesis by impairing retinoid signaling. Retinoid signaling may be the main pathogenetic disorder in COVID-19. This pathogenesis can serve as a guide for adjuvants, drug targets, and candidate drugs. Retinol, retinoic acid derivatives, and some CYP450 inhibitors may work on COVID-19.

There are many chemicals that can cause burns. Although they are generally acidic and basic in nature, there are more than one million known chemical compounds, of which 300 have been declared highly hazardous chemical substances by the National Fire Protection Society. Chemical burns account for approximately 10.7% of all burn injuries and 30% of deaths because of burns. Chemicals can be classified as acid, alkali, organic, and inorganic compounds. Acids act by denaturing and coagulating proteins. Alkaline burns cause deeper burns than acid burns.

Background/Objectives. Most patients that require port operation have experienced severe pain due to multiple surgeries in the past. Therefore, these patients have fear of pain before the procedure. This study aims to compare superficial cervical plexus block (SCPB) with local infiltration anesthesia in terms of comfort. Methods. 100 cancer-diagnosed patients were divided into two groups. The first group, the landmark technique with local infiltration anesthesia, was used for intravenous entry (Group LM, n = 50). The second group, USG, was used for venous entry with SCPB as anesthesia (Group US, n = 50). The type of local anesthesia, port placement technique, duration of the procedure, number of procedures, complications, visual analog scale (VAS) score, and surgeon’s satisfaction with the procedure were recorded. Results. It was established that an average of 1.7 and 1.1 attempts was conducted in Groups LM and US, respectively (P = 0.010). VAS scores were found to be 4.04 in Group LM and 2.62 in GroupUS (P = 0.001). Surgeon satisfaction was 1.96 in GroupLM and 2.38 in GroupUS (P = 0.014). The mean duration of the procedure was 22.10 minutes in GroupLM and 43.50 minutes in GroupUS (P = 0.001). Complication rates were observed in 1 patient in GroupLM and 9 patient in GroupUS (P = 0.040). Conclusions. In the patient group with a high level of pain and anxiety port catheter placement using USG and SCPB, supported by routine sedation, provides better comfort for both patient and surgeon.

Studies on the frequency of burned limbs according to season and months are limited. The burning of some body limbs, especially in some months, shows that the causes of burns are different, and knowing the reasons is important for providing preventive measures. The aims of this study were to determine the distribution rate of child burns by months and seasons and to contribute to preventive measures by determining the distribution of the burning of body limbs by months. We retrospectively evaluated 419 paediatric patients (0‐17 years of age) who were hospitalised in the burn unit between 1 May 2017 and 1 November 2018. The demographic characteristics of the patients were recorded according to age, gender, months, and seasons of the patients admitted; cause of burns; degree of burns; total body surface area; and burning regions. The distribution of burns by months was established as being mainly in May to October. As for the distribution of the patients according to the seasons, it was found that it was most common in summer, 122 (29.1%), and in the autumn season as well, it was 122 (29.1%). While body burns increased in the summer‐autumn seasons (P < .023), genital area burns were the lowest in winter and were the highest in summer and autumn seasons. Genital site burns increased statistically in September, October, and November (P < .010). Burn traumas are observed to be more frequent in some seasons and months. The environments where individuals live, forms of life, forms of warming, areas of interest, and sociocultural and economic levels are the causes of this variability.
