Hot-press hand injury caused by roller type ironing machine.

Thermal crush burn injury due to roller type ironing press machine is relatively rare and can cause destructive effects with significant morbidity. These injuries can be avoided by taking some basic precautions. Early debridement after admission and definitive treatment after the extent of injury are delineated and these are the preferred approaches in the management. We present a case of thermal crush injury of the hand caused by laundry roller type ironing press machine.

Serum neuron-specific enolase and S-100ß levels as prognostic follow-up markers for oxygen administered carbon monoxide intoxication cases.

Serum neuron-specific enolase (NSE) and S-100ß levels are considered novel biochemical markers of neuronal cell injury. In this study, the initial and post-treatment levels of NSE and S-100ß were compared in carbon monoxide (CO) poisoning patients, who received normorbaric oxygen (NBO) or hyperbaric oxygen (HBO) therapy. Forty consecutive patients with acute CO poisoning were enrolled in this prospective, observational study. According to their clinical symptoms and observations, twenty patients were treated with NBO, and the other twenty with HBO. Serum S-100ß and NSE levels were measured both at time of admission and 6 h later (post-treatment). Serum NSE and S-100ß values decreased significantly in both of the therapeutic modalities. The initial and post-treatment values of NSE and S-100ß in NBO or HBO patients were comparable. A clear negative correlation was observed between the decrease of NSE and S-100ß levels and initial blood carboxyhemoglobin levels. In conclusion, the present results suggested the use of serum S-100ß and NSE levels as indicators for brain injury. Due to the significant increase of their values with oxygen therapy, they may also be useful as prognostic follow-up markers. However, the current findings reflected no difference between the efficacy of NBO or HBO therapy.

Evaluation of autopsy reports in terms of preventability of traumatic deaths.

BACKGROUND: The analysis of autopsy reports plays an important role in the evaluation of trauma care quality. The objective of this study was to determine the rate of preventable deaths and medical errors in regard to the autopsy reports as an indicator of trauma care quality in traumatic deaths. METHODS: A retrospective review of traumatic autopsy reports kept between 2011 and 2012 in Eskisehir, Turkey was conducted. Demographic data of the cases, injury type, injury mechanism, injury location, ISS values, and cause and place of death were recorded. Deaths were judged in three groups including preventable deaths, potentially preventable deaths and non-preventable deaths. In the definiton of preventability, the criteria of American College of Surgeons Committee on Trauma were used. A commission composed of two forensic medicine specialists and one emergency medicine specialist reviewed preventability and defined medical errors. RESULTS: A total of five hundred and ninety-two autopsy reports were examined in the study period. Trauma was defined as the cause in 65.2% (n=386) of the cases. 81.9% (n=316) of the cases were observed to have suffered blunt injury and 18.1% (n=70) penetrating injury. Death occurred at the scene of trauma in 56.7% (n=219) of the cases, in the pre-hospital period in 11.7% (n=45), and in hospital in 31.6% (n=122). In preventability analysis, it was decided that 4.1% (n=16) of the cases had the properties of being preventable, 14.5% (n=56) potentially preventable and 81.3% (n=314) non-preventable. Suboptimal care was determined in 65.3% (n=47) of the total cases, delayed intervention in 58.3% (n=42), error in the medical method decision in 8.3% (n=6), delayed or wrong diagnosis in 1.4% (n=1), and inappropriate or incorrect medical application in 1.4% (n=1). CONCLUSION: High rates of preventable deaths in the pre-hospital period, in cases of penetrating injuries, and particularly in cases of chest trauma were evaluated as noteworthy findings. Integrated working of pre-hospital emergency healthcare services with trauma centres would enable the development of trauma care and reduce the rates of preventable deaths.

PARP inhibition prevents acetaminophen-induced liver injury and increases survival rate in rats.

BACKGROUND/AIM: Acetaminophen (APAP) overdose results in severe liver damage that may develop into acute liver failure. Recent studies have demonstrated that inhibition of poly(ADP-ribose) polymerase (PARP) decreases tissue necrosis and inflammation. We evaluated the efficacy of 3-aminobenzamide (3-AB), a PARP inhibitor, in a rodent model of APAP-induced hepatotoxicity. MATERIALS AND METHODS: Twenty-four Sprague-Dawley rats were divided equally into 3 experimental groups: sham group, APAP group, and APAP + 3-AB group. In the experimental treatment groups APAP was administered orally at 1 g/kg and, in the APAP + 3-AB group, 3-AB was administered intraperitoneally at a dose of 20 mg/kg exactly 1 h after APAP treatment. Surviving animals were euthanized 48 h after initial APAP administration. Blood samples and liver tissues were collected for histopathological and biochemical analysis. RESULTS: A panel of oxidative stress parameters, as well as serum aspartate aminotransferase, alanine aminotransferase, neopterin, and nitrite/nitrate and histological injury scores, were significantly reduced among the APAP + 3-AB treatment group relative to the group treated with APAP alone (P < 0.05, APAP vs. APAP + 3-AB). CONCLUSION: The present study demonstrates that 3-AB inhibited APAP-induced hepatic injury and reduced neopterin levels. Results of the present study indicate that PARP inhibitors may be an effective adjuvant therapy resulting in improved outcomes in APAP-induced hepatotoxicity.

Psychiatric Symptoms and Quality of Life in Military Personnel Deployed Abroad.

BACKGROUND: Military personnel deployed abroad could be exposed to more risk factors that adversely affect quality of life. In this study, we examined psychiatric symptoms and quality of life in Turkish Armed Forces deployed to Afghanistan. METHOD: A total of 289 Turkish military personnel working in Afghanistan enrolled in this study. They completed two surveys containing questions about socio-demographic characteristics. Data were collected and analyzed from 258 of the participants. RESULTS: The general symptom scores (GSI) were above 1 in 20.8 Percent (n=54) of the participants. The lowest SF-36 scores by the sub-groups were mental health (59.14 ± 18.56) and vitality (59.25 ± 21.17). The highest score was in the physical function subscale (84.42 ± 19.53). All Quality of Life Questionnaire Short Form (SF-36)subscale scores were lower in the GSI above 1 group than the GSI below 1 group. In the GSI above 1 group: education level and depression affected SF-36 physical functioning; paranoid ideation and somatization affected SF-36 role limitations due to physical health; age and somatization affected SF-36 pain; age affected SF-36 general health; phobic anxiety affected SF-36 vitality; age, tenure of occupation, tenure abroad; and phobic anxiety affected SF-36 mental health. CONCLUSIONS: The negative effects of psychiatric symptoms on the quality of life were similar to those in the general population and in specific disease groups. These results should be considered when evaluating the mental health of military personnel deployed abroad.

Effectiveness of the Stewart Method in the Evaluation of Blood Gas Parameters.

OBJECTIVES: In 1981, Peter A. Stewart published a paper describing his concept for employing Strong Ion Difference. In this study we compared the HCO3 levels and Anion Gap (AG) calculated using the classic method and the Stewart method. METHODS: Four hundred nine (409) arterial blood gases of 90 patients were collected retrospectively. Some were obtained from the same patients in different times and conditions. All blood samples were evaluated using the same device (ABL 800 Blood Gas Analyzer). HCO3 level and AG were calculated using the Stewart method via the website AcidBase.org. HCO3 levels, AG and strong ion difference (SID) were calculated using the Stewart method, incorporating the parameters of age, serum lactate, glucose, sodium, and pH, etc. RESULTS: According to classic method, the levels of HCO3 and AG were 22.4±7.2 mEq/L and 20.1±4.1 mEq/L respectively. According to Stewart method, the levels of HCO3 and AG were 22.6±7.4 and 19.9±4.5 mEq/L respectively. CONCLUSIONS: There was strong correlation between the classic method and the Stewart method for calculating HCO3 and AG. The Stewart method may be more effective in the evaluation of complex metabolic acidosis.

Effects of hypothermia on skeletal ischemia reperfusion injury in rats.

OBJECTIVE: The aim of this study was to investigate the effect of hypothermia (H) on skeletal ischemia-reperfusion (IR) injury in rats by measuring malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), nitric oxide (NO), and interleukin-1 beta (IL-1ß) in muscle, and measureing immunohistochemical-inducible nitric oxide synthase (iNOS) staining of skeletal muscle. MATERIALS AND METHODS: Eighteen Wistar Albino rats were divided randomly into three groups (sham, IR, hypothermia) (n=6). The sham group had all procedures without the IR period. The lower right extremity of rats in the IR and hypothermia groups was subjected to 2 hours of ischemia and 22 hours of reperfusion by applying a clamp on the common iliac artery and a rubber-band at the level of the lesser trochanter under general anesthesia. Rats in the hypothermia group underwent 4 hours of hypothermia during the first four hours of reperfusion in addition to a 2-hour ischemia and 22-hour reperfusion period. All rats were sacrificed at end of the IR period using a high dose of anesthesia. The tibialis anterior muscles were preserved. Immunohistochemical iNOS staining was performed, and MDA, SOD, GSH-Px, NO, and IL-1ß were measured in the muscle. RESULTS: The level of MDA, NO, and IL-1ß in muscle was increased in the IR group compared with that in the sham group, but these parameters were decreased in the hypothermia group compared with the IR group. The activities of SOD and GSH-Px in muscle were decreased in the IR group; however, these parameters were increased in the hypothermia group. The score and intensity of iNOS staining of skeletal muscle was dens in IR group, mild in hypothermia group, and weak in sham group. CONCLUSION: The present study has shown that hypothermia reduced IR injury in the skeletal muscle by decreasing the levels of MDA, NO, and IL-1ß, and increasing the activities of SOD and GSH-Px. In addition, hypothermia attenuated the score and intensity of iNOS staining.

Neopterin, homocysteine, and ADMA levels during and after urticaria attack.

BACKGROUND/AIM: Urticaria is a vascular skin reaction characterized with papules and plaques. Neopterin is accepted as an immunologic marker and an indicator of activation of the immune system. Homocysteine and asymmetric dimethylarginine (ADMA) are the markers of increased vascular resistance. Alteration in vascular resistance has a role in the pathogenesis of urticaria. We aimed to investigate whether there is a relationship between urticaria and neopterin, homocysteine, or ADMA. MATERIALS AND METHODS: The study is designed as a prospective descriptive study and patients with a diagnosis of urticaria in the emergency department were included in the study. Demographic data and characteristics of the disease were recorded. Neopterin, homocysteine, and ADMA levels were measured both during and after urticaria attacks. All data were statistically analyzed. RESULTS: The differences between neopterin levels measured during and after urticaria attacks were statistically significant (P < 0.001). The differences between homocysteine and ADMA levels measured during and after urticaria attacks were not statistically significant (P > 0.05). CONCLUSION: Our results indicate that neopterin levels in patients with urticaria attacks are increased and the level of neopterin is also a useful parameter in acute urticaria. Further studies should clarify whether homocysteine levels contribute to diagnosis of acute urticaria. However, no relation was found between ADMA and urticaria.

Ozone therapy ameliorates paraquat-induced lung injury in rats.

Paraquat (PQ) overdose can cause acute lung injury and death. Ozone therapy (OT) was previously demonstrated to alleviate inflammation and necrosis in various pathologies. We therefore hypothesized that OT has ameliorative and preventive effects on PQ-induced lung damage due to anti-inflammatory and antioxidants properties. Sprague-Dawley rats (n = 24) were separated into three groups: sham, PQ, and PQ+OT groups. 15 mg/kg PQ was administered intraperitoneally in PQ and PQ+OT groups to induce experimental lung injury. One hour after PQ treatment, PQ+OT group was administered a single dose of ozone-oxygen mixture (1 mg/kg/day) by intraperitoneal route for four consecutive days. The animals were sacrificed on fifth day after PQ administration. Blood samples and lung tissues were collected to evaluate the inflammatory processes, antioxidant defense and pulmonary damage. Serum lactate dehydrogenase (LDH) and neopterin levels, tissue oxidative stress parameters, total TGF-ß1 levels, and histological injury scores in PQ+OT group were significantly lower than PQ group (P<0.05, PQ vs. PQ+OT). Total antioxidant capacity in PQ+OT group was significantly higher than PQ group (P < 0.05, PQ+OT vs. PQ). These findings suggest that outcome in PQ-induced lung injury may be improved by using OT as an adjuvant therapy.

Effectiveness of hyperbaric oxygen and ozone applications in tissue healing in generated soft tissue trauma model in rats: an experimental study.

BACKGROUND: Soft tissue trauma is a type of acute traumatic ischemia. We investigated in this study whether the edema, inflammation and ischemia caused by the trauma could be affected positively by hyperbaric oxygen (HBO) and ozone therapy. METHODS: Soft tissue trauma was generated in a total of 63 adult male Sprague-Dawley rats. Subsequently, rats were divided into three groups. The first group was treated with ozone, the second group with HBO, and the third group served as controls. Tissue and blood samples were taken at the end of the procedures. Tissue lipid peroxidation (LPO), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), inducible nitric oxide synthase (iNOS), heme oxygenase (HO)-1, and hypoxia-inducible factor (HIF)-1 levels were detected. Hematoxylin-eosin staining was used to determine the inflammation and edema histopathologically. RESULTS: We also detected HIF-1 activity, which decreases when the oxygen concentration increases, HO-1 activity, which has anti-inflammatory effects, and iNOS activity, which releases in any type of acute case. We determined a statistically significant reduction in iNOS and LPO levels in both the HBO and Ozone groups. A significant decrease in inflammation was detected in both the Ozone and HBO groups compared with the Control group, and a significant decrease in edema was detected in all three groups. CONCLUSION: We think that HBO and Ozone therapy have beneficial effects on biochemical and histopathological findings. Related clinical trials will be helpful in clarifying the effects.

A comparison of suprascapular nerve block and procedural sedation analgesia in shoulder dislocation reduction.

OBJECTIVES: Dislocation of the shoulder joint is one of the most common dislocations. The reduction procedure is a painful procedure. In this study, 2 different treatment groups were compared for pain control during shoulder dislocation reduction. It was aimed to evaluate the differences between the groups in reduction, success, length of hospital stay, complications, side effects, patient-physician satisfaction, and ease of application. METHODS: The study was planned to be prospective and randomized. As procedural sedation analgesia (SA), titration of ketamine 1 to 2 mg/kg was administered intravenously to group 1. Suprascapular nerve block (SNB) was applied under ultrasound guidance (USG) to group 2. Conformity to normal distribution of variables was examined with the Kolmogorov-Smirnov test. The χ2 test and Fisher test were used to evaluate differences between the groups in categorical variables and the Mann-Whitney U test, and a value of P<.05 was accepted as statistically significant. RESULTS: The study comprised a total of 41 patients; 20 in the group 1 and 21 in the group 2. No statistically significant difference was determined between the groups in terms of age (P=.916), sex (P=.972), reduction success (P=.540), and patient-physician satisfaction (P=.198). The time spent in the emergency department (ED) by patients in the SA group was signficantly longer compared with the SNB group. No side effects were observed in the SNB group. CONCLUSIONS: Suprascapular nerve block, which can be easily applied under USG in the ED, can be evaluated as a good alternative to SA in the reduction of shoulder dislocations.

[The relationship between Injury Severity Scores and transfusion requirements of 108 consecutive cases injured with high kinetic energy weapons: a tertiary center end-mode mortality analysis]. / Yüksek kinetik enerjili silahlarla yaralanmis ardisik 108 olguya ait ISS degerleri ile transfüzyon gereksinimleri arasindaki iliski ve ileri merkez son mod mortalite analizi.

BACKGROUND: We aimed in this study to investigate the relationship between Injury Severity Score (ISS) and transfusion strategies required during medical intervention in patients wounded by high kinetic energy (HKE) gunshot, and to analyze end-mode mortality. METHODS: The medical data of patients were included in the study. We evaluated whether there was any significant correlation in terms of demographic characteristics, HKE weapon type, ISSs, and transfusion strategy options and transfusion requirements. RESULTS: Causes of mortality in cases resulting in mortality during hospitalization were evaluated. One hundred and eight consecutive patients were included in the study. All patients except one were male, with an average age of 25 years. 64.8% of them were injured by long-barreled firearms, whereas 35.2% were injured by explosives. Average ISS was 13.9. ISS values for the patients with and without transfusion were 16 (5-48) and 9 (3-36), respectively. Causes of mortality were evaluated in terms of systemic inflammatory response syndrome (SIRS), sepsis, and multiorgan dysfunction syndrome (MODS). DISCUSSION: It was determined that there was a significant correlation between increase in ISS values in cases with HKE weapon wounds and their transfusion requirements, whereas this requirement was independent of the ISS value in cases with explosive wounds.
