RESUMEN
OBJECTIVES: Supraglottic airway (SGA) devices are good alternatives for failed intubations or difficult airways. The aim of our study was to compare the success of intubation with SGA devices such as LMA Fastrach® (LMA Fastrach), Ambu Aura-i® (Aura-i), and Cookgas Air-Q® (Air-Q) in an airway manikin by novice practitioners. METHODS: This study was conducted in a randomized crossover design using a manikin model. Following training on the equipment used, 36 6th-year medical students were randomized into six groups. Participants performed three stages of intubation as follows: the first stage (1S) as SGA insertion, the second stage (2S) as intubation through the SGA, and the third stage (3S) as the removal of the SGA over the intubation tube. The primary outcomes were intubation success and duration. RESULTS: The successful intubation rate (Stage 1S + 2S + 3S) was 100% for LMA Fastrach and Air-Q and 83.3% for Aura-i (P = 0.002). The median time to intubation was 54.4 s, 55.8 s, and 58.7 s for LMA Fastrach, Aura-i, and Air-Q, respectively (P = 0.794). CONCLUSION: Our study shows that novice practitioners can proficiently utilize LMA Fastrach, Air-Q, and Aura-i as SGAs in airway management. LMA Fastrach and Air-Q are more successful for endotracheal intubation than Aura-i. While the successful intubation time with SGA is similar for all three devices, the successful SGA insertion time is shorter with LMA Fastrach and Aura-i compared to Air-Q. Practitioners preferred LMA Fastrach and Air-Q more than Aura-i.
RESUMEN
OBJECTIVES: Several scoring systems are used to predict prognosis in acute pancreatitis (AP), but their predictive success varies. This study compares the validity of the commonly used Bedside Index of Severity in AP (BISAP) score with the newly developed WL score and the Chinese Simple Scoring System (CSSS) score in predicting mortality and unfavorable prognostic outcomes in AP patients. METHODS: This retrospective descriptive study included all AP patients presenting to the emergency department from June 2, 2019, to June 2, 2022. Patient demographics, vital signs, laboratory values, and imaging findings were recorded, and WL, CSSS, and BISAP scores were calculated. The effectiveness of these scores in predicting adverse outcomes and mortality was compared. RESULTS: Among 357 patients, 53.2% were male, with a median age of 62 years (interquartile range: 48-75). Area under the curve (AUC) values for 7-day outcomes were 0.956 for WL, 0.759 for CSSS, and 0.871 for BISAP; for 30-day outcomes, AUC values were 0.941 for WL, 0.823 for CSSS, and 0.901 for BISAP; and for poor prognostic outcomes, AUC values were 0.792 for WL, 0.769 for CSSS, and 0.731 for BISAP. CONCLUSION: In AP patients, WL, CSSS, and BISAP scores are effective predictors of unfavorable prognosis and mortality. WL score outperforms the CSSS and BISAP scores in predicting 7-day and 30-day mortality and poor prognosis. After WL, BISAP is the second-best system for predicting mortality. For predicting unfavorable prognoses, CSSS is the second-best system after WL. The simplicity of calculating the WL score based on four laboratory parameters makes it a preferable choice.
RESUMEN
AIMS: The National Early Warning Score (NEWS) is a scoring system that predicts increased mortality and morbidity in critical diseases. The National Early Warning Score + Lactate (NEWS + L) score was created by adding lactate values to this scoring system. In our study, we aimed to determine the value of the NEWS + L score in predicting clinical deterioration in patients presenting with acute decompensated heart failure (chronic heart failure). METHODS AND RESULTS: In this observational, cross-sectional study, patients with decompensated heart failure who were admitted to the emergency department between 1 October 2020 and 31 December 2020 were included. Patients were divided into two groups: those with and without poor prognostic outcomes. The main outcomes were in-hospital mortality, discharge after treatment in the emergency department, admission to the ward, and admission to the intensive care unit. We analysed a total of 141 applications from 130 patients. The mean age was 72.6 ± 11.8 years, and 50.8% were female. Poor prognostic outcomes were observed in 92 (65%) patients. There was no difference between the patients with and without poor prognostic outcomes in terms of mean age, gender, and comorbidities, except for atrial fibrillation. There was a statistically significant difference between the patients without and with poor prognosis outcomes in terms of NEWS {3 [interquartile range (IQR): 0-5] and 6 [IQR: 3-8]} and NEWS + L scores [4.7 (IQR: 2.3-7.2) and 8.0 (IQR: 5.2-10.4)] (P < 0.001). The area under the curve values for predicting poor prognosis were calculated as 0.719 for NEWS, 0.734 for NEWS + L, and 0.601 for lactate values. The rate of poor prognostic outcomes was higher (79%) in patients with moderate and high NEWS scores. Patients with Q1 NEWS + L scores had a lower rate of poor prognostic outcomes, while patients with Q2, Q3, and Q4 scores of NEWS + L had a higher rate of poor prognostic outcomes. CONCLUSIONS: The NEWS score and the addition of the lactate value to this score, the NEWS + L score, were higher in patients with poor prognostic outcomes who presented with decompensated heart failure in our emergency department. NEWS + L slightly outperformed the NEWS score in predicting prognosis. The NEWS + L score shows promise as a prognostic indicator for patients with decompensated heart failure presenting to the emergency department.

BACKGROUND: This study aims to reveal whether the optic nerve sheath diameter (ONSD) increases in hepatic encephalopathy (HE) patients, and to determine ONSD is associated with the poor prognosis of patients with HE. METHODS AND MATERIAL: In this retrospective case-control study, HE patients who underwent cranial computerized tomography (CT) were included in the case group; and the patients who underwent CT for other reasons for the same age and gender and were normally interpreted were included in the control group. ONSD measurements in the case and control groups and clinical grades of HE with in-hospital mortality and ONSD measurements were compared in the case group. RESULTS: This study was done with 74 acute HE patients and 74 control patients. The mean age was 62.9 ± 11.0 years and 67.6% of patients were male in both groups. The ONSD in the case group was higher than the control group (5.27-mm ± 0.82 vs 4.73 mm ± 0.57, p <0.001). In the case group, the ONSD was 5.30 mm ± 0.87 in survivors, and 5.21 ± 0.65 in non-survivors (P = 0.670). There was no significant difference between the West Haven HE grade (P = 0.348) and Child-Pugh Score (P = 0.505) with ONSD measurements. CONCLUSION: We have shown that ONSD increases in HE patients compared to the control group. ONSD was not related to the Child-Pugh Score, HE grade, and in-hospital mortality.

OBJECTIVE: We aimed to determine the effect of fibrinolytic therapy on hemodynamic parameters at 4 hours after treatment and bleeding complications in patients with intermediate- and high-risk pulmonary embolism. METHODS: This single-center, retrospective, cohort study included patients with intermediate- and high-risk pulmonary embolism treated with fibrinolytics. Their demographic and clinical characteristics, complications, and vital signs at the initiation of and 4 hours after fibrinolytic therapy were evaluated. The primary outcome was the change in the patients' vital signs at 4 hours after fibrinolytic therapy, compared by the Mann-Whitney U-test. RESULTS: Seventy-nine patients were included in this study. The systolic and diastolic blood pressures of the high-risk group at 4 hours after fibrinolytic therapy were higher than those at the initiation of fibrinolytic therapy (80 mmHg vs. 99 mmHg, P = 0.029; 49 mmHg vs. 67 mmHg, P = 0.011, respectively). In the intermediate-risk group, the oxygen saturation increased (94% vs. 96%, P = 0.004) and pulse rate decreased (104 beats/min vs. 91 beats/min, P < 0.001). CONCLUSION: Blood pressure at 4 hours after fibrinolytic therapy increased in patients with high-risk pulmonary embolism. Also, oxygen saturation and pulse rate improved in intermediate-risk patients.
RESUMEN
It's known that head computed tomography (CT) is used excessively to exclude intracranial hemorrhage in patients with hepatic encephalopathy (HE) in the emergency department. However, the independent risk factors for abnormal head CT in patients with HE have not been studied extensively to date. In this retrospective study, patients with an ammonia level of >90 U/L who were clinically considered HE and had head CT were included. The characteristics of patients with abnormal head CT and independent risk factors for abnormal CT were investigated. Three hundred seventy-eight patients were included in the study. CT findings of 18 (4.8%) of the patients were abnormal: 12 had intracranial hemorrhage, 1 had an ischemic stroke, and 5 had an intracranial mass. Intracranial hemorrhage (odds ratio [OR] 12.5), history of recent trauma (OR 23.4), history of active malignancy (OR 10.3), thrombocyte count <100.000/µL (OR 4.3), and international normalized ratio ≥1.5 (OR 3.2) were found to be independent risk factors for abnormal head CT. Head CT scan may be considered in patients with HE if any of the following are present: intracranial bleeding history, recent trauma history, active malignancy, platelet count <100,000/µL, and international normalized ratio >1.5.

PURPOSE: We aimed to compare the diagnostic value of fine-needle aspiration cytology (FNAC) and fine-needle aspiration thyroglobulin measurements (FNA-Tg) for detecting cervical lymph node metastases from differentiated thyroid carcinomas. METHODS: This prospective study included 225 patients with neck node metastases or recurrences of papillary thyroid carcinoma. From the 225 patients, 255 lymph nodes were evaluated by FNAC and FNA-Tg. Final diagnoses confirmed by histological examination were compared to preoperative FNAC and FNA-Tg results. RESULTS: FNAC correctly diagnosed 212 metastatic lymph nodes but failed to diagnose 43 of them. FNA-Tg correctly diagnosed 253 metastatic lymph nodes but failed to diagnose two of them. FNA-Tg levels showed 100% sensitivity, 96% specificity, 99% diagnostic accuracy, a 99% positive predictive value (PPV) and a 100% negative predictive value (NPV) with a threshold level of FNA-Tg with a diagnostic accuracy 28.5 ng/ml. The specificity, diagnostic accuracy, PPV and NPV of FNA-Tg were significantly higher than those of FNAC. CONCLUSION: FNA-Tg measurement can be performed safely for the detection of lymph node metastasis in patients with differentiated thyroid carcinomas.

INTRODUCTION: Neurofibromatosis type 1 is a genetic disease characterized by neoplastic and non neoplastic disorders involving tissues of neuroectodermal and mesenchymal origin. Herein, we present a case with von Recklinghausen's disease, right adrenal heochromocytoma and multiple gastrointestinal stromal tumors. PRESENTATION OF CASE: A forty-eight year old male patient was admitted to our Emergency Department with melena. His physical examination revealed multiple neurofibromas all over the skin, kyphosis, multiple cafe au lait spots and Lisch nodules on the eye and, melena on digital rectal examination. Abdominal computerized tomography scan showed a mass on right adrenal gland and multiple soft tissue mass lesions between distal part of pancreas and small bowel. Adrenal mass was determined as a pheochromocytoma and small bowel lesions were verified as stromal tumors. DISCUSSION: In patients with NF1, pheochromocytomas and GISTs are well known neoplasms seen with increased incidence than the general population. CONCLUSION: In patients with NF1, any symptoms with other systems should be managed carefully for underlying malignity.
RESUMEN
One form of prolactin (PRL) is macroprolactin with high molecular mass. Many macroprolactinemic patients have no pituitary adenomas and no clinical symptoms of hyperprolactinemia, it is controversial whether macroprolactinemia is a benign condition that does not need further investigation and treatment. In this study, we aimed to compare macroprolactinemic patients (group I) with the true hyperprolactinemic patients (group II) for the presence of pituitary adenoma. We investigated 161 patients with hyperprolactinemia, whose magnetic resonance imaging records of the pituitary were taken. All patients were questioned for irregular menses, infertility and examined for galactorrhea. Patients were screened for macroprolactinemia by polyethylene glycol precipitation, and a recovery of ≤40% and normal monomeric PRL level was taken as an indication of significant macroprolactinemia. Of 161 patients with hyperprolactinemia, 60 (37.26%) had macroprolactinemia. PRL levels of group II were lower than those of group I (P = 0.011), although monomeric PRL levels of group II were higher than those of group I (P = 0.0005). Of 60 macroprolactinemic patients, 16 (26.7%) had pituitary adenomas. The prevalence of pituitary adenomas was lower in group I, compared with group II (P = 0.0005). No significant differences were found between the prevalences of irregular menses and infertility of group I and II (P = 0.084, P = 0.361). Prevalence of galactorrhea in group I was lower than that in group II (P = 0.048). Prevalence of pituitary adenomas in macroprolactinemic patients is lower compared with the true hyperprolactinemic patients, but may be higher than that found in other recent studies and in the general population.

BACKGROUND: Several methods have been recommended to detect parathyroid lesions in patients who have previously undergone neck surgeries, including radio-guided surgery or intraoperative ultrasounds. In this study, we aimed to investigate whether the radio-guided excision of pathologic parathyroid lesions allowed us to find affected lesions in patients who had previously undergone neck operations. METHODS: This prospective study included 18 patients with primary hyperparathyroidism who had previously undergone neck surgeries. The pathologic parathyroid lesions were localized by ultrasonography, and a radiotracer was injected directly into the lesions. RESULTS: Careful dissections were carried out by following the area of maximum radioactivity until the lesions were identified and excised. Eighteen parathyroid adenomas were removed in 18 patients. The median count from each lesion was significantly higher than the values measured from the adjacent tissues and the lesion beds (12550/20 s, 370/20 s, and 35/20 s, respectively; p < 0.001). CONCLUSION: Radio-guided excision of parathyroid lesions can be performed safely for re-operative parathyroid surgery.

The Bethesda system (BS) for reporting thyroid fine-needle aspiration (FNA), which classifies nodules as nondiagnostic (ND), benign (B), atypia/follicular lesion of undetermined significance (AUS/FLUS), suspicious for follicular neoplasm (SFN/FN), suspicious for malignancy (SFM), or malignant (M), uses clinically valuable management guidelines. The authors employed a similar in-house classification system (IS) for thyroid FNAs, using the categories of ND, B, suspicious follicular cells (SFC), follicular lesion/neoplasm (FL/FN), SFM, and M. The authors compared IS and BS, and assessed the utility of BS in clinical practice. A total of 581 nodules with cytological/histological follow-up were examined and indeterminate lesions by BS were reclassified. The sensitivity and specificity for malignancy using IS were similar to that of BS (77% vs 99%). However, when SFN/FN and SFM were both considered positive, the results for IS and BS were as follows: sensitivity, 85% versus 85%; specificity, 87% versus 94%; and diagnostic accuracy, 86% versus 90%, respectively. Discrepancies between cytological and histological data were evident in 35 cases among all categories of BS except AUS/FLUS. The rate of surgery for nonmalignant nodules was lesser (20% vs 9%) by BS. Among 34 AUS/FLUS cases with follow-up data, hypocellularity was the case in 11 (46%) nonneoplastic and 10 (100%) neoplastic nodules. The use of BS results in a lower rate of surgery for nonmalignant nodules even though patients with borderline cytopathologic features are still encountered. AUS/FLUS category can be separated into subgroups according to the factors causing difficulties in the interpretation. There is a need of accumulation of AUS/FLUS cases to do further evaluations and studies.
