Medical and legal evaluation of injuries due to dog bites: a Türkiye study.

BACKGROUND: Dog bites are the most common type of injury related to animal bites in our country and worldwide. Dog bite wounds pose significant public health concerns and have medicolegal implications. In this study, we aimed to assess the problems associated with dog bites and propose potential solutions. METHODS: We conducted a retrospective analysis of 149 cases submitted by judicial authorities to our institution, the Istanbul Council of Forensic Medicine, between 2015 and 2021, to obtain medicolegal expert opinion reports. Information regarding the cases included in the study was obtained from our archives and the National Judicial Network Project (UYAP) system. Data were recorded using Microsoft Excel 2016, and statistical analysis was performed using SPSS 25.0 for Windows (SPSS Inc., Chicago, IL). RESULTS: The mean age of the cases was 33.7 years, with 57% being male. 56.4% of the incidents occurred in the city center, and 30.9% took place during the summer months. 65.8% (n=98) of the cases were attributed to stray dogs. Superficial injuries without muscle tissue involvement were observed in 54.4% (n=81) of all cases, while 22.8% (n=34) had deep tissue defects or flap injuries, 4.7% (n=7) involved vascularnerve injuries, 16.1% (n=24) included bone fractures, and 2% (n=3) featured visceral injuries. Surgical treatment was performed on 37.5% (n=56) of the cases. Impairments were reported in 22.1% of the cases, with permanent facial scars affecting 16.7% of them. Psychiatric evaluations were required for 48.9% (n=89) of the cases, and 57.5% of them received a diagnosis of post-traumatic stress disorder. CONCLUSION: People attacked by dogs may experience serious physical or psychological sequelae. Therefore, it is crucial to evaluate all victims using a multidisciplinary approach, addressing their physical, social, and psychological needs, and providing rehabilitation when necessary. Non-governmental organizations, such as those dedicated to the prevention of cruelty to animals, in collaboration with local veterinary services, should play a role in national initiatives to provide objective and humane solutions for both victims and animals.

Comparison of sequential organ failure assessment score and cardiac surgery score systems for mortality prediction after emergency acute aortic dissection surgery.

BACKGROUND: Acute type A aortic dissection (ATAAD) is one of the most mortal cardiovascular diseases and requires urgent diagnosis and surgery. The patient's clinical findings, complications, and patient's history are closely related to mortality rates. Cardiac surgery score (CASUS) is a scoring system which is calculated by considering the special pathophysiological conditions of patients undergoing cardiac surgery and predicts post-operative results with high accuracy. METHODS: Following the ethical approval from institutional ethics committee (ID: 2021/7/496), the data of consecutive 50 ATAAD patients who underwent emergent surgery in our hospital between January 1, 2019, and December 31, 2020, were evaluated. The Sequential Organ Failure Assessment and CASUS scores were calculated using the worst values of the daily laboratory and neurological status for both in admission to emergency department and during intensive care unit (ICU) follow-up period. The average and the total values of these scores were recorded for pre-operative, post-operative 1st day, and for the categorical data were defined as frequency and percentage. We used the Mann-Whitney U test for the independent continuous data comparisons and Pearson Chi-Square or Fisher exact test for categorical data comparison whole ICU period. Continuous data were presented as median and interquartile ranges (25-75th). RESULTS: The study comprised 50 patients, the rate of death was 34% (n=17). In total group, there were hypertension 72% (n=36), diabetes mellitus 24% (n=12), initial hemoglobin 12.5 g/dL (10.7-14.1, 25-75th), creatinine 1.09 mg/dL (0.85-1.33, 25-75th), and 72% (n=36) of these patients were male. The CASUSmean and SOFAmean scores were higher in the death-group when compared with the group who survived (12.9 [9.5-13.8, 25-75th], 3 [2-5, 25-75th]; 8 [6.1-9.2, 25-75th], 2.6 (2-4.5, 25-75th], p<0.001, respectively]. CASUSmean was independently associated with the 1-month mortality in model 1 (HR 1.25 [1.14-1.37] (p<0.001). CONCLUSION: According to our results increase in CASUS mean was the main predictor of 1 month mortality. When CASUS mean exceeds 8.3 the patient should be followed up more carefully for major adverse events including death.

Extracorporeal cardiopulmonary resuscitation in-hospital cardiac arrest due to acute coronary syndrome.

BACKGROUND: The aim of this study was to analyze the effect of extracorporeal cardiopulmonary resuscitation on survival and neurological outcomes in in-hospital cardiac arrest patients. METHODS: Between January 2018 and December 2020, a total of 22 patients (17 males, 5 females; mean age: 52.8±9.0 years; range, 32 to 70 years) treated with extracorporeal cardiopulmonary resuscitation using veno-arterial extracorporeal membrane oxygenation support for in-hospital cardiac arrest after acute coronary syndrome were retrospectively analyzed. The patients were divided into two groups as those weaned (n=13) and non-weaned (n=9) from the veno-arterial extracorporeal membrane oxygenation. Demographic data of the patients, heart rhythms at the beginning of conventional cardiopulmonary resuscitation, the angiographic and interventional results, survival and neurological outcomes of the patients before and after extracorporeal cardiopulmonary resuscitation were recorded. RESULTS: There was no significant difference between the groups in terms of comorbidity and baseline laboratory test values. The underlying rhythm was ventricular fibrillation in 92% of the patients in the weaned group and there was no cardiac rhythm in 67% of the patients in the non-weaned group (p=0.125). The recovery in the mean left ventricular ejection fraction was significantly evident in the weaned group (36.5±12.7% vs. 21.1±7.4%, respectively; p=0.004). The overall wean rate from veno-arterial extracorporeal membrane oxygenation was 59.1%; however, the discharge rate from hospital of survivors without any neurological sequelae was 36.4%. CONCLUSION: In-hospital cardiac arrest is a critical emergency situation requiring instantly life-saving interventions through conventional cardiopulmonary resuscitation. If it fails, extracorporeal cardiopulmonary resuscitation should be initiated, regardless the underlying etiology or rhythm disturbances. An effective conventional cardiopulmonary resuscitation is mandatory to prevent brain and body hypoperfusion.

Anesthetic management in lung transplantation: Our single-center experience.

BACKGROUND: In this study, we aimed to discuss our anesthesia management strategies, experiences, and outcomes in patients undergoing lung transplantation. METHODS: Between December 2016 and December 2018, a total of 53 patients (43 males, 10 females; mean age: 46.1±13 years; range, 14 to 64 years) undergoing lung transplantation in our center were included. The anesthesia technique, patients" characteristics, and perioperative clinical and follow-up data were recorded. The stage of lung disease was assessed using the New York Heart Association functional classification. RESULTS: Two patients underwent single lung transplantation, while 51 patients underwent double lung transplantation. Idiopathic pulmonary fibrosis was the most common indication in 41.5% of the patients. All patients had end-stage lung disease (Class IV) and 79% were oxygen-dependent. The extracorporeal membrane oxygenation support was given to 32 patients. CONCLUSION: The anesthetic management of lung transplantation is challenging, either due to the deterioration of the recipient"s physical performance and the complexity of the surgical techniques used. In general, a kind of mechanical support may be needed and extracorporeal membrane oxygenation is the first choice in the majority of patients. A close communication should be maintained between the surgeons, perfusion technicians, and anesthesiologists to ensure an optimal multidisciplinary approach and to achieve successful outcomes.

The role of intraoperative pulmonary arterial catheterization data in determining the need for extracorporeal membrane oxygenation in lung transplantation.

BACKGROUND: This study aims to investigate predictive factors of identification of the need of patients for extracorporeal membrane oxygenation support during lung transplantation. METHODS: A total of 63 patients (49 males, 14 females, mean age: 44.9±14.4 years; range, 14 to 64 years) who underwent lung transplantation in our institution between December 2016 and December 2019 were retrospectively analyzed. Demographic characteristics and perioperative clinical data of patients were recorded. After induction and pulmonary artery catheterization, cardiac output, mean pulmonary artery pressure, pulmonary capillary wedge pressure, cardiac index, pulmonary vascular resistance, systemic vascular resistance, and right atrial pressure were measured using the thermodilution technique. RESULTS: Thirty-three of the patients received extracorporeal membrane oxygenation support during surgery. The right atrial pressure (p<0.001), pulmonary capillary wedge pressure (p<0.002), mean pulmonary artery pressure (p<0.001), and pulmonary vascular resistance (p<0.001) were statistically significantly higher in the patients who required extracorporeal membrane oxygenation support intraoperatively. The systemic vascular resistance (p<0.032) was statistically significantly lower in the patients who required extracorporeal membrane oxygenation support intraoperatively. A mean pulmonary artery pressure of >39 mmHg (p<0.02) and a right atrial pressure of >12 mmHg (p<0.047) were independent risk factors for ECMO support intraoperatively during lung transplantation. CONCLUSION: Predicting the need of intraoperative extracorporeal membrane oxygenation support is of utmost importance in timing the need for mechanical support, protecting the new graft from high mechanical ventilator pressures, and adequately maintaining hemodynamic stability.

A new hemoglobin variant: Hb Izmir [ß86(F2)Ala→Val, GCC>GTC; HBB:c.260C>T].

We report a new hemoglobin (Hb) variant [ß86(F2)Ala→Val; HBB:c.260C>T] that we have named Hb Izmir. We have identified Hb Izmir in a Turkish woman by ion exchange high performance liquid chromatography (HPLC) during a premarital screening program in the Aegean region of Turkey. The mother and sister of the proband also carried the same variant. Using direct sequencing, we have characterized this variant as resulting from a GCC>GTC replacement at codon 86 of the ß-globin chain, corresponding to an Ala→Val amino acid substitution. In the heterozygote, the level of Hb Izmir ranged from 41.38 to 45.6%. All heterozygotes had a Hb A(2) level of less than 3.5%. Total blood count values were normal and there were no other clinical findings. Although its clinical significance is thus far unclear, Hb Izmir may be important in hemoglobinopathy screening programs.

Hb Sarrebourg [ß131(H9)Gln→Arg, CAG>CGG] in Turkey.

We describe Hb Sarrebourg [ß131(H9)Gln→Arg, CAG>CGG] in four heterozygous members of a Turkish family. It was associated with iron deficiency in the proband.

The association between estimated average glucose levels and fasting plasma glucose levels.

OBJECTIVE: The level of hemoglobin A1c (HbA1c), also known as glycated hemoglobin, determines how well a patient's blood glucose level has been controlled over the previous 8-12 weeks. HbA1c levels help patients and doctors understand whether a particular diabetes treatment is working and whether adjustments need to be made to the treatment. Because the HbA1c level is a marker of blood glucose for the previous 120 days, average blood glucose levels can be estimated using HbA1c levels. Our aim in the present study was to investigate the relationship between estimated average glucose levels, as calculated by HbA1c levels, and fasting plasma glucose levels. METHODS: The fasting plasma glucose levels of 3891 diabetic patient samples (1497 male, 2394 female) were obtained from the laboratory information system used for HbA1c testing by the Department of Internal Medicine at the Izmir Bozyaka Training and Research Hospital in Turkey. These samples were selected from patient samples that had hemoglobin levels between 12 and 16 g/dL. The estimated glucose levels were calculated using the following formula: 28.7 x HbA1c - 46.7. Glucose and HbA1c levels were determined using hexokinase and high performance liquid chromatography (HPLC) methods, respectively. RESULTS: A strong positive correlation between fasting plasma glucose levels and estimated average blood glucose levels (r=0.757, p<0.05) was observed. The difference was statistically significant. CONCLUSION: Reporting the estimated average glucose level together with the HbA1c level is believed to assist patients and doctors determine the effectiveness of blood glucose control measures.

Inverse relationship between adiponectin and plasminogen activator inhibitor-1 in metabolic syndrome patients.

OBJECTIVES: To determine the serum levels of adiponectin and plasminogen activator inhibitor-1 in metabolic syndrome versus healthy controls and to see the relation of them with each other and with the metabolic syndrome components. METHODS: Adiponectin and plasminogen activator inhibitor-1 levels were measured in 53 subjects with metabolic syndrome and 30 healthy controls by ELISA. All subjects of metabolic syndrome had the criterias of metabolic syndrome (obesity, insulin resistance, hypertension, dyslipidemia, glucose metabolism disorders). Adiponectin and plasminogen activator inhibitor-1 levels in serum were compared between the groups and relations of them with each other, with metabolic syndrome components, also HbA1c and C peptide were examined. For statistical analysis student-t test and pearson's correlations were used. RESULTS: Metabolic syndrome group had significantly lower adiponectin and higher plasminogen activator inhibitor-1 levels than healthy controls (p<0.001). There was no difference between the average age of both groups. There was an inverse relationship between plasma adiponectin and plasminogen activator inhibitor-1 ( r= -0.653, p<0.001). Also adiponectin levels were inversely correlated with body mass index (BMI), waist and hip circumferences, systolic and diastolic pressures, fasting plasma glucose, 2 hour postprandial serum glucose, HbA1c, C peptide, triglycerides, total cholesterol, insulin and insulin resistance (HOMA). Plasminogen activator inhibitor-1 levels were correlated positively with these parameters. CONCLUSION: Hypoadiponectinemia and elevated plasminogen activator inhibitor-1 levels were closely associated with the metabolic syndrome and its components, inverse relationship was present between adiponectin and plasminogen activator inhibitor-1 levels in metabolic syndrome patients. It is suggested that measuring and regulating the plasma concentration of adiponectin and plasminogen activator inhibitor-1 may be useful for management of the metabolic syndrome so this may prevent the development of obesity, cardiovascular diseases and diabetes.

The value of serum zinc, copper, ceruloplasmin levels in patients with gastrointestinal tract cancers.

BACKGROUND/AIMS: Gastrointestinal cancers are frequent diseases of particular importance for surgeons with regard to their management and follow-up. Neoplastic diseases activate antioxidant defense systems. As a result, concentrations of redoxal enzymes and their co-factor elements appear to change. The levels of zinc (Zn), copper (Cu) and ceruloplasmin have been found to be critical parameters. In addition, it seems to be important to consider the Cu/Zn ratio in such cases. In this study, changes in the levels of Cu, Zn and ceruloplasmin in patients with gastrointestinal system cancers was evaluated, and the proportion of Cu to Zn (Cu/Zn) is discussed. METHODS: In this clinical trial, levels of Cu and Zn were defined with calorimetric methods and ceruloplasmin levels were measured with immunohistochemical methods in a control group of 20 healthy individuals and in 25 patients who underwent surgery for gastrointestinal system cancer. The blood samples were taken preoperatively in gastrointestinal system cancer patients. RESULTS: This study has shown that while the decrease in Zn levels and the increase in ceruloplasmin levels in patients with gastrointestinal system cancers were found to be significant (p<0. 001, p=0. 014) when compared to the control group, the increase in the level of Cu was also found to be significant (p=0. 019). In the patient group, the correlations between serum Cu and serum ceruloplasmin proved to be significant (r=991, p<0. 001). The Cu/Zn ratio, when compared with Zn, ceruloplasmin and Cu, showed significant results (r= 0. 562, r= 0. 500, r=0. 506, p<0. 001). CONCLUSIONS: This study shows that serum Cu, Zn and ceruloplasmin levels show changes in gastrointestinal system cancers, but further research is needed to demonstrate the importance and significance of these parameters and their relation with other contributing neoplastic factors.
