An Evaluation of the National Early Warning Score 2 and the Laboratory Data Decision Tree Early Warning Score in Predicting Mortality in Geriatric Patients.

BACKGROUND: Due to the high rate of geriatric patient visits, scoring systems are needed to predict increasing mortality rates. OBJECTIVE: In this study, we aimed to investigate the in-hospital mortality prediction power of the National Early Warning Score 2 (NEWS2) and the Laboratory Data Decision Tree Early Warning Score (LDT-EWS), which consists of frequently performed laboratory parameters. METHODS: We retrospectively analyzed 651 geriatric patients who visited the emergency department (ED), were not discharged on the same day from ED, and were hospitalized. The patients were categorized according to their in-hospital mortality status. The NEWS2 and LDT-EWS values of these patients were calculated and compared on the basis of deceased and living patients. RESULTS: Median (interquartile range [IQR]) NEWS2 and LDT-EWS values of the 127 patients who died were found to be statistically significantly higher than those of the patients who survived (NEWS2: 5 [3-8] vs. 3 [1-5]; p < 0.001; LDT-EWS: 8 [7-10] vs. 6 [5-8]; p < 0.001). In the receiver operating characteristic curve analysis, the NEWS2, LDT-EWS, and NEWS2+LDT-EWS-formed by the sum of the two scoring systems-resulted in 0.717, 0.705, and 0.775 area under curve values, respectively. CONCLUSIONS: The NEWS2 and LDT-EWS were found to be valuable for predicting in-hospital mortality in geriatric patients. The power of the NEWS2 to predict in-hospital mortality increased when used with the LDT-EWS.

The role of the neutrophil-lymphocyte ratio in the diagnosis of cerebral venous sinus thrombosis.

OBJECTIVES: We aimed to assist in the diagnosis of cerebral venous sinus thrombosis (CVST) with the neutrophil-lymphocyte ratio (NLR). BACKGROUND: Diagnosis of CVST is difficult. METHODS: Patients, who visited the emergency department between March 1, 2013 and March 1, 2021 and underwent magnetic resonance (MR) venography were included. The patients' MR venography results, ages, gender, NLR, were collected. The patients were categorized according to their CVST diagnosis status, and NLR were compared. RESULTS: Of the 530 patients included in the study, 366 (69.1 %) were female, and the median age was 40 (31-58) years. CVST was detected in 57 (10.8 %) patients, no pathological diagnosis was detected in 251 (47.4 %) patients. The median NLR of the patients with CVST was statistically significantly higher than in the patients without CVST and in the patients without any diagnosis ((3.94 [2.5-6.47] vs 3.03 [1.93-5.43], p = 0.023) (3.94 [2.5-6.47] vs 2.92 [1.86-4.95], p = 0.009). In the ROC analysis performed with reference to the patients without any diagnosis, NLR obtained 0.612 AUC. CONCLUSION: Significantly higher NLR levels were found in CVST patients compared to the patients, who were not diagnosed with CVST and the patients without any diagnosis (Tab. 5, Fig. 2, Ref. 22).

The role of the BUN/albumin ratio in predicting mortality in COVID-19 patients in the emergency department.

INTRODUCTION: Due to the high mortality and spread rates of coronavirus disease 2019 (COVID-19), there are currently serious challenges in emergency department management. As such, we investigated whether the blood urea nitrogen (BUN)/albumin ratio (BAR) predicts mortality in the COVID-19 patients in the emergency department. METHODS: A total of 602 COVID-19 patients who were brought to the emergency department within the period from March to September 2020 were included in the study. The BUN level, albumin level, BAR, age, gender, and in-hospital mortality status of the patients were recorded. The patients were grouped by in-hospital mortality. Statistical comparison was conducted between the groups. RESULTS: Of the patients who were included in the study, 312(51.8%) were male, and their median age was 63 years (49-73). There was in-hospital mortality in 96(15.9%) patients. The median BUN and BAR values of the patients in the non-survivor group were significantly higher than those in the survivor group (BUN: 24.76 [17.38-38.31] and 14.43 [10.84-20.42], respectively [p < 0.001]; BAR: 6.7 [4.7-10.1] and 3.4 [2.5-5.2], respectively [p < 0.001]). The mean albumin value in the non-survivor group was significantly lower than that in the survivor group (3.60 ± 0.58 and 4.13 ± 0.51, respectively; p < 0.001). The area-under-the-curve (AUC) and odds ratio values obtained by BAR to predict in-hospital COVID-19 mortality were higher than the values obtained by BUN and albumin (AUC of BAR, BUN, and albumin: 0.809, 0.771, and 0.765, respectively; odds ratio of BAR>3.9, BUN>16.05, and albumin<4.01: 10.448, 7.048, and 6.482, respectively). CONCLUSION: The BUN, albumin, and BAR levels were found to be reliable predictors of in-hospital mortality in COVID-19 patients, but BAR was found to be a more reliable predictor than the BUN and albumin levels.

Predictive value of D-dimer/albumin ratio and fibrinogen/albumin ratio for in-hospital mortality in patients with COVID-19.

INTRODUCTION: Due to the high mortality of coronavirus disease 2019 (COVID-19), there are difficulties in the managing emergency department. We investigated whether the D-dimer/albumin ratio (DAR) and fibrinogen/albumin ratio (FAR) predict mortality in the COVID-19 patients. METHODS: A total of 717 COVID-19 patients who were brought to the emergency department from March to October 2020 were included in the study. Levels of D-dimer, fibrinogen and albumin, as well as DAR, FAR, age, gender and in-hospital mortality status of the patients, were recorded. The patients were grouped by in-hospital mortality. Statistical comparison was conducted between the groups. RESULTS: Of the patients included in the study, 371 (51.7%) were male, and their median age was 64 years (50-74). There was in-hospital mortality in 126 (17.6%) patients. The area under the curve (AUC) and odds ratio values obtained by DAR to predict in-hospital mortality were higher than the values obtained by the all other parameters (AUC of DAR, albumin, D-dimer, FAR and fibrinogen: 0.773, 0.766, 0.757, 0.703 and 0.637, respectively; odds ratio of DAR > 56.36, albumin < 4.015, D-dimer > 292.5, FAR > 112.33 and fibrinogen > 423:7.898, 6.216, 6.058, 4.437 and 2.794, respectively). In addition; patients with concurrent DAR > 56.36 and FAR > 112.33 had an odds ratio of 21.879 with respect to patients with concurrent DAR < 56.36 and FAR < 112.33. CONCLUSION: DAR may be used as a new marker to predict mortality in COVID-19 patients. In addition, the concurrent high DARs and FARs were found to be more valuable in predicting in-hospital mortality than either separately.

Prognostic Value of Immunosuppressive Acidic Protein and Oxidative Stress Status in Critically Ill Patients.

INTRODUCTION: The aim of this study was to determine the prognostic value of admission immunosuppressive acidic protein (IAP), interleukin-6 (IL-6), total oxidant status (TOS), and total antioxidant status (TAS) in 161 critically ill patients. MATERIALS AND METHODS: This prospective observational study was carried out in the Emergency Department ICU for 6 months. Critically ill patients were included in the study consecutively. The main outcomes were the need for early mechanical ventilation (MV) and in-hospital mortality. RESULTS: The mean age of 161 patients was 66.5 ± 17.1 years. The median IL-6 levels of patients who required early MV were significantly higher than of the patients who required no MV (p < 0.001), and the median IL-6 levels in the nonsurvivors were significantly higher than in the survivors (p < 0.001). The median IAP levels were not significantly different between the groups (p = 0.464 for early MV and p = 0.340 for the in-hospital mortality group). The AUCs of IL-6 and TOS for predicting in-hospital mortality were 0.819 and 0.608, respectively. CONCLUSION: The IAP level on admission to ICU is ineffective in predicting the need for early MV and in-hospital mortality; however, IL-6 level on admission is a strong prognostic predictor in critically ill patients. Our findings showed that the burden of oxidative stress was high in general ICU patients. CLINICAL SIGNIFICANCE: Our study showed that increased oxidative stress is an important problem in critically ill patients. If measures are taken to reduce oxidative stress by physicians, the prognosis of critically ill patients will be better.

Lactate and NEWS-L are fair predictors of mortality in critically ill geriatric emergency department patients.

INTRODUCTION: In this study, we aimed to investigate the prognostic power of the first lactate level measured in the emergency department (ED), National Early Warning Score (NEWS), and NEWS-lactate (NEWS-L) on ED admission in critically ill geriatric patients. METHODS: This retrospective observational study was conducted in the ED of a university hospital. Consecutive patients ≥65 years of age admitted to our ED between July 1, 2017, and December 31, 2017, and transferred to the intensive care unit after the ED follow-up period were included in the study. The predictive performances of lactate, NEWS, and NEWS-L in terms of in-hospital mortality were compared. RESULTS: A total of 455 patients were included in the statistical analyses. The in-hospital mortality rate was 22.9%. The mean lactate, NEWS, and NEWS-L of non-survivors was significantly higher than those of survivors (2.9 ±â€¯2.2 vs. 1.9 ±â€¯1.5 mmol/L, 8.9 ±â€¯4.1 vs. 6.1 ±â€¯3.7, and 11.8 ±â€¯5.0 vs. 8.1 ±â€¯4.4, respectively, for all p < 0.001). The AUCs of the lactate, NEWS, and NEWS-L were respectively 0.654 (95% CI 0.594-0.713), 0.686 (95% CI 0.628-0.744), and 0.714 (95% CI 0.658-0.770) in predicting in-hospital mortality. CONCLUSIONS: According to the results of this study, we conclude that ED admission lactate level and NEWS are low-accuracy predictors of in-hospital mortality in critically ill geriatric patients. Although the combination of lactate level with physiological parameters increases the predictive performances of both parameters, NEWS-L is still not a powerful predictor to make definitive clinical decisions for critically ill geriatric ED patients.

The role of soluble urokinase plasminogen activator receptor (SuPAR) as an indicator of the severity of acute pancreatitis

Background/aim: Soluble urokinase plasminogen activator receptor (suPAR) has been reported to have a positive correlation with the activation degree of the immune system. This study's aim is to investigate the efficiency of SuPAR serum levels in acute pancreatitis (AP) patients in determining the severity of disease. Materials and methods: This prospective research involves patients who arrived at the emergency service, were over 18 years old, had nontraumatic abdominal pain and diagnosis of AP, and agreed to join the study. Demographic characteristics, contact information, laboratory and imaging test parameters, Ranson's criteria, the Balthazar Severity Index, the Rapid Acute Physiologic Score (RAPS), and the modified Glasgow (Imrie) score of all patients were recorded. Two study groups were created as score of <3 (mild, Group I) and ≥3 (severe, Group II) for pancreatitis according to Ranson's criteria. Results: During the study period, 59 sequential patients with AP were included in the study. It was seen that 79.7% of the study group (n = 47) were in Group I. Etiologically 67.8% (n = 40) cases were biliary and 32.3% (n = 19) were nonbiliary diseases. According to the results, suPAR level was effective in distinguishing the severity of AP (AUC = 0.902, P < 0.001 (95% CI: 0.821­0.984)). With regard to determining severe disease, suPAR had an optimum cutoff value of 6.815 ng/mL, sensitivity of 91.66%, specificity of 82.97%, and negative predictive value of 97.5%. Conclusion: Our study was performed the determine the efficiency of suPAR level in predicting severe disease in AP patients. We found it significant in indicating the severity of disease according to the study results.

The Effect of Out-of-Hours Admission on Mortality in Patients Who Underwent Thrombectomy Due to Ischemic Stroke.

Background: It is important to investigate the factors that may delay the diagnosis and treatment process of ischemic stroke. The aim of this study was to investigate whether in-hospital mortality increased in patients who presented to the emergency department out-of-hours and underwent thrombectomy. Methods: A total of 59 patients who applied to the emergency department between January 1, 2018 and November 1, 2021 and underwent thrombectomy due to ischemic stroke were included in the study. Patient age, gender, thrombectomy success (successful recanalization), in-hospital mortality status, intracranial hemorrhage status after thrombectomy, and out-of-hours admission status were recorded and compared according to out-of-hours admission status. Results: Twenty-seven (45.8%) patients were male, and the median age was 74 (61-81) years. Forty-two (71.2%) patients applied to the emergency department out-of-hours. In-hospital mortality occurred in 27 (45.8%) patients. There was no statistically significant difference in out-of-hours admission status between the non-survivor group and the survivor group (non-survivor: 24 [75%]; survivor: 18 [66.7%], p = 0.481). Nor was a statistically significant difference found in the intracranial hemorrhage complication rate of the patients admitted out-of-hours compared to the patients admitted during working hours (out-of-hours: 17 [40.5%]; during working hours: 6 [35.3%], p = 0.712). Conclusion: No statistically significant difference was found in the rate of in-hospital mortality and intracranial bleeding complications in patients who underwent thrombectomy out of working hours compared to during working hours.

Efficacy of aprotinin treatment on bilateral blunt chest trauma created in rabbits.

OBJECTIVES: To investigate the effects of aprotinin, on blood gasses, oxidant-antioxidant status, and lung histopathology in an experimental bilateral blunt chest trauma model. METHODS: Conducted at the Experimental Animal Laboratory of Meram Medical School at Selcuk University, Konya, Turkey, the study comprised 21 New Zealand female albino rabbits who were divided into three groups.Trauma was applied on the sham and aprotinin groups, which was administered intravenous Aprotinin 20.000 U/kg. Arterial blood samples were obtained from all rabbits at hours 0, 3, 24, and 96. At hour 96 after trauma, all rabbits were sacrificed using the decapitation method, and then blood and lung tissue samples were obtained. Blood nitric oxide, malondialdehyde and blood gas measurements were made. Histopathological changes in the lung were examined with a light microscope. RESULTS: While no positive effect of aprotinin was observed on nitric oxide malondialdehyde and partial pressure of carbon dioxide values, it was seen to have an increasing effect on partial oxygen pressure level. Aprotinin had a partial effect on lung histopathology. CONCLUSION: Aprotinin was determined to have a positive effect on PO2 levels. We could not find any positive effects especially on alveolar haemorrhage.

Diagnostic value of ischemia-modified albumin in acute coronary syndrome and acute ischemic stroke.

OBJECTIVE: To investigate diagnostic value of ischemia-modified albumin (IMA) levels in patients applying to emergency with symptoms of acute coronary syndrome (ACS) and acute ischemic stroke (AIS). METHODS: Two patient groups (ACS and AIS) and a control group were constituted. The study was discontinued upon reaching 30 patients in each group. Following patient approval at the initial visit, a total of 10 ml venous blood sample was obtained from all patients with a high clinical suspicion of ACS and AIS. The Troponin I and the IMA levels were determined in the blood samples. RESULTS: Statistically significant higher IMA values were determined in the patient groups compared to the control group (p<0.001 for both groups). No statistically significant correlation was found between the IMA and the Troponin I values in the ACS and the AIS groups (p>0.05 for both groups). The sensitivity of IMA was 83% and 87% for ACS and AIS, respectively. The specificity of IMA was 90% and 87% for ACS and AIS, respectively. CONCLUSION: The sensitivity and specificity values, determined according to the optimal cut-off values in the groups demonstrated that IMA could be a useful diagnostic marker in ACS and AIS patients.

The Role of Procalcitonin/Albumin Ratio and CRP/Albumin Ratio in Predicting In-hospital Mortality in COVID-19 Patients.

Background: Hospitalized coronavirus disease 2019 (COVID-19) patients have higher mortality rates. Parameters to predict mortality are needed. Therefore, we investigated the power of procalcitonin/albumin ratio (PAR) and C-reactive protein/albumin ratio (CAR) to predict in-hospital mortality in hospitalized COVID-19 patients. Methods: In this study, 855 patients were included. Patients' PAR and CAR values were recorded from the hospital information management system. The patients were evaluated in two groups according to their in-hospital mortality status. Results: In-hospital mortality was observed in 163 patients (19.1%). The median PAR and CAR values of patients in the non-survivor group were statistically significantly higher than those of patients in the survivor group, PAR (median: 0.07, interquartile range [IQR]: 0.03-0.33 vs. median: 0.02, IQR: 0.01-0.04, respectively; p < 0.001); CAR (median: 27.60, IQR: 12.49-44.91 vs. median: 7.47, IQR: 2.66-18.93, respectively; p < 0.001). The area under the curve (AUC) and odds ratio (OR) values obtained by PAR to predict in-hospital mortality were higher than the values obtained by procalcitonin, CAR, albumin, and CRP (AUCs of PAR, procalcitonin, CAR, albumin, and CRP: 0.804, 0.792, 0.762, 0.755, and 0.748, respectively; OR: PAR > 0.04, procalcitonin > 0.14, CAR > 20.59, albumin < 4.02, and CRP > 63; 8.215, 7.134, 5.842, 6.073, and 5.07, respectively). Patients with concurrent PAR > 0.04 and CAR > 20.59 had an OR of 15.681 compared to patients with concurrent PAR < 0.04 and CAR < 20.59. Conclusions: In this study, PAR was found to be more valuable for predicting in-hospital COVID-19 mortality than all other parameters. In addition, concurrent high levels of PAR and CAR were found to be more valuable than a high level of PAR or CAR alone.

Serum intestinal fatty acid binding protein and phosphate levels in the diagnosis of acute intestinal ischemia: an experimental study in rabbits.

BACKGROUND: Acute intestinal ischemia is a serious clinical disorder with mesenteric infarction, which has high mortality. It is important to establish a biochemical marker for the early diagnosis of acute intestinal ischemia. OBJECTIVES: The aim of this experimental study was to assess the changes in the serum levels of intestinal fatty acid binding protein (IFABP) and phosphate by time using the acute intestinal ischemia model in rabbits. METHODS: In this study, 21 New Zealand rabbits were randomly divided into three groups. Blood samples were obtained at 0, 1, 3, and 6 h in the control group. Blood samples were obtained at 0, 1, 3, and 6 h in the sham group after simple laparotomy. Blood samples were obtained at the same hours in the ischemia group after simple laparotomy and ligation of the superior mesenteric artery. RESULTS: There was no significant difference between the control, the sham, and the ischemia groups in terms of serum IFABP levels at any time (p > 0.05). Serum phosphate levels significantly increased in the ischemia group (p < 0.001). Studies on IFABP have begun emerging in the literature, and there is no standard approach for the technique to measure the IFABP level. No studies on IFABP were found in the literature on rabbits. CONCLUSION: Based on our results, the role that IFABP levels play in the diagnosis of acute intestinal ischemia is unclear at this time. Serum phosphate levels continued to rise as the duration of ischemia was prolonged. These findings support the suggestion that serum phosphate levels are valuable for the diagnosis of acute intestinal ischemia.

Prognostic value of heparin-binding protein for mortality in severe COVID-19 pneumonia.

Aim: The study investigated heparin-binding protein (HBP) levels in patients with severe COVID-19 pneumonia and their relation to prognosis. Methods: A total of 134 patients with serious COVID-19 pneumonia were prospectively analyzed. HBP levels were statistically compared between both the patient and healthy control groups and within the patient group itself. Results: HBP was defined to be significantly higher in the patient group compared with the control group. There was a statistically significant distinction between the patients who survived and those who died with regard to HBP levels. When the cutoff value of HBP was >13.47, sensitivity (89.8%), specificity (74.1%) had area under the curve values of 0.806 (p < 0.001). Conclusion: HBP level may be used for prognosis prediction of patients with COVID-19.

Bag-Valve-Mask versus Laryngeal Mask Airway Ventilation in Cardiopulmonary Resuscitation with Continuous Compressions: A Simulation Study.

INTRODUCTION: The 2017 International Liaison Committee on Resuscitation (ILCOR) guideline recommends that Emergency Medical Service (EMS) providers can perform cardiopulmonary resuscitation (CPR) with synchronous or asynchronous ventilation until an advanced airway has been placed. In the current literature, limited data on CPR performed with continuous compressions and asynchronous ventilation with bag-valve-mask (BVM) are available. STUDY OBJECTIVE: In this study, researchers aimed to compare the effectiveness of asynchronous BVM and laryngeal mask airway (LMA) ventilation during CPR with continuous chest compressions. METHODS: Emergency medicine residents and interns were included in the study. The participants were randomly assigned to resuscitation teams with two rescuers. The cross-over simulation study was conducted on two CPR scenarios: asynchronous ventilation via BVM during a continuous chest compression and asynchronous ventilation via LMA during a continuous chest compression in cardiac arrest patient with asystole. The primary endpoints were the ventilation-related measurements. RESULTS: A total of 92 volunteers were included in the study and 46 CPRs were performed in each group. The mean rate of ventilations of the LMA group was significantly higher than that of the BVM group (13.7 [11.7-15.7] versus 8.9 [7.5-10.3] breaths/minute; P <.001). The mean volume of ventilations of the LMA group was significantly higher than that of the BVM group (358.4 [342.3-374.4] ml versus 321.5 [303.9-339.0] ml; P = .002). The mean minute ventilation volume of the LMA group was significantly higher than that of the BVM group (4.88 [4.15-5.61] versus 2.99 [2.41-3.57] L/minute; P <.001). Ventilations exceeding the maximum volume limit occurred in two (4.3%) CPRs in the BVM group and in 11 (23.9%) CPRs in the LMA group (P = .008). CONCLUSION: The results of this study show that asynchronous BVM ventilation with continuous chest compressions is a reliable and effective strategy during CPR under simulation conditions. The clinical impact of these findings in actual cardiac arrest patients should be evaluated with further studies at real-life scenes.

The role of heparin-binding protein in the diagnosis of acute mesenteric ischemia.

BACKGROUND: Acute mesenteric ischemia (AMI) is associated with a high mortality rate, yet diagnostic difficulties persist. Although many biomarkers have been investigated for diagnostic purposes, as well as imaging methods, a sufficiently specific and sensitive marker has not been identified. This research was designed to examine whether heparin-binding protein (HBP), which has a role in the early phase of inflammation, could be useful in the diagnosis of AMI. METHODS: Serum samples obtained from a previously performed rabbit model of AMI were used in the study. HBP, C-reactive protein (CRP) and interleukin 6 (IL-6) levels were measured in blood samples obtained at baseline and 1, 3, and 6 hours from subjects that were separated into 3 groups: control, sham, and ischemia. The change in each marker over time and comparisons of the groups were evaluated statistically. RESULTS: A significant difference was not detected at the first hour in any of the studied markers. At the third hour, the CRP and IL-6 levels in the ischemia group indicated a significant increase in comparison with the control and sham groups (p<0.001). The HBP values showed a significant increase at the sixth hour in the ischemia group in comparison with the others (p<0.001). CONCLUSION: The HBP level demonstrated a slower increase in a rabbit model of AMI compared with CRP and IL-6. However, it still has the potential to become an early diagnostic biomarker. Diagnostic sensitivity and specificity should be evaluated in further clinical trials.

The effects of mannitol and melatonin on MRI findings in an animal model of traumatic brain edema.

OBJECTIVES: The aim of this study was to compare the effects of mannitol and melatonin on brain edema secondary to trauma using magnetic resonance imaging (MRI). METHODS: A mild traumatic brain injury with the Feeney method was performed upon twelve New Zealand rabbits. Three hours after the trauma was inflicted, MRI images were obtained, then the subjects were divided into two groups: a mannitol group and a melatonin group. The mannitol group (n = 6) was given 2 gr/kg of 20% mannitol IV over 10 minutes and the melatonin group (n = 6) received 100 mg/kg of melatonin IV over 30 minutes. Thirty-three hours after the first MRI, MRI was repeated. The 3-hour and 36-hour post-trauma MRI images in both groups were scored regarding signs of edema and extent of brain tissue protrusion in a blinded fashion by a staff radiologist. Intragroup and intergroup comparisons were made using the Fisher exact test and chi square test. Comparison of brain tissue protrusion measurements was done using the Mann Whitney U test. RESULTS: Signs of raised intraventricular pressure, contusion and parenchymal edema were more prevelant, and parenchymal protrusion was more prominent on the 36-hour MRI in both mannitol and melatonin groups. No significant difference was found between the melatonin and mannitol groups in any parameter in the MRI images performed 3 and 36 hours after the head trauma. CONCLUSIONS: In this animal model, melatonin and mannitol had similar effects on brain edema, as demonstrated on MRI 3 and 36 hours after head trauma.

Phenytoin induced dystonia.

Acar T, Alkan G, Çaksen H, Ertekin B, Ergin M, Koçak S, Cander B. Phenytoin induced dystonia. Turk J Pediatr 2018; 60: 111-112. The abnormalities of dopaminergic activity in the basal ganglia have been emphasized to be effective in dystonia. We hereby report a case of a 2.5-year-old male patient who presented with tonic-clonic sezures and who developed dystonia after being given phenytoin. Biperidene hydrochloride was administered intramuscularly; primidone was added to the treatment regimen. After a 7-day-follow-up at the hospital, the patient had no dystonia and was discharged.

Stevens-Johnson syndrome due to concomitant use of lamotrigine and valproic acid.

Stevens-Johnson syndrome (SJS) is a rare but life-threatening acute mucocutaneous hypersensitivity reaction, usually related to drugs. Severe cutaneous adverse effects such as SJS and toxic epidermal necrolysis can arise during treatment with antiepileptic drugs (AEDs). A 23-year-old female patient with idiopathic epilepsy was referred to the emergency service with fever, oral and genital mucosal lesions, generalized rash, and weakness. She had been taking carbamazepine, valproic acid, and lamotrigine until 1 week prior to referral. Following consultations with a range of clinicians, the patient was diagnosed with SJS related to lamotrigine on the basis of her history and physical findings, and on consideration of current consensus definitions of this condition. The patient was followed up and treated in the emergency intensive care unit with intravenous fluids, antibacterial therapy, and methylprednisolone. After 18 days, the patient was considered to have made a sufficient recovery and was discharged. Patients who undergo therapy with AEDs, particularly new users of these agents, should be informed of and monitored for possible systemic and cutaneous adverse effects of AEDs. Polytherapy should be avoided for as long as possible as this increases the frequency of adverse effects, and treatment should be discontinued if any rash appears.

The role of optic nerve ultrasonography in the diagnosis of elevated intracranial pressure.

OBJECTIVE: To evaluate the convenience and utility of optic nerve ultrasonography (ONUS) in the evaluation of emergency patients with elevated intracranial pressure (EICP) due to traumatic or non-traumatic causes. METHODS: This study was conducted between May 2005 and December 2005 in the emergency department of Meram Faculty of Medicine, Selcuk University. Patients with traumatic or non-traumatic EICP were included in the study. Among these, 28 patients with EICP determined on cranial computed tomography (CCT) and a control group of 26 patients with no disease had the vertical and horizontal diameters of the optic nerves (ONs) of both eyes measured by ultrasonography (US). The measurements were done by wetting the closed eyelids and using a 7.5-MHz linear probe. RESULTS: Horizontal and vertical diameters of both ONs of the 54 patients were measured and the averages calculated. The mean (SD) ON diameter for the group suspected of having EICP was found to be 6.4 (0.7) mm, and that for the control group to be 4.6 (0.3) mm. In the statistical analysis carried out between these two groups (t test), the difference was found to be significant at p<0.001. CONCLUSIONS: In detection and follow-up of EICP cases, such as cerebrovascular accident and trauma, ONUS is a practical, risk-free, inexpensive, convenient and, if performed by experts, reliable method. As a result, although CCT may be more useful in diagnosis, ONUS may be more efficient in detecting EICP. In those cases where CCT and other conventional imaging methods are not available, ONUS can facilitate the diagnosis and help in treatment.

Lipoprotein-associated phospholipase-A2 activity and its diagnostic potential in patients with acute coronary syndrome and acute ischemic stroke.

BACKGROUND: The study examined the Lp-PLA2 activity at the patients presented to the emergency department with acute coronary syndrome (ACS) or acute ischemic stroke (AIS), as well as its diagnostic value. METHODS: The prospective study included consecutive male and female patients aged >18 years that presented to the our emergency department with ACS or AIS between November 2009 and January 2010. Blood samples were obtained immediately following diagnosis in the ACS and AIS groups. The diagnostic value of Lp-PLA2 was determined based on receiver operating characteristic curves, sensitivity, specificity, predictive values, likelihood ratios and accuracy rates. RESULTS: In all, 34 ACS and 32 AIS patients were included in the study, and the control group included 35 patients. Lp-PLA2 enzyme activity was significantly lower in the ACS and AIS groups than in the control group (26.7 ± 13.8, 31.4 ± 13.6, and 41.4 ± 8.1 nmol min-1·mL-1, respectively; p < 0.0001, p = 0.022). In the ACS group the area under the curve (AUC) was 0.825 (95%CI: 0.722-0.929), sensitivity was 71% for an optimal Lp-PLA2 cut-off value of 31.4 nmol min-1·mL-1, and specificity was 91%, whereas in the AIS group the AUC was 0.768 (95%CI: 0.652-0.884), sensitivity was 75% for an optimal Lp-PLA2 cut-off value of 38.1 nmol min-1·mL-1, and specificity was 74%. CONCLUSIONS: Lp-PLA2 enzyme activity was significantly lower during the early stage of both ACS and AIS. The obtained statistic data suggest that low Lp-PLA2 enzyme activity can be used for diagnostic purposes.
