Diagnostic role of thoracic ultrasound in patients with acute respiratory failure at emergency service.

BACKGROUND AND AIM: This study aimed to elucidate the effectiveness of bedside thoracic ultrasound according to BLUE protocol and to investigate its superiority over other imaging methods in the emergency service. METHODS: A total of 120 patients admitted to our institution's emergency care department due to respiratory distress have been enrolled in this prospective research. Thorax USG has been performed in the right and left hemithorax at the points specified in the BLUE protocol for each patient. Pleural sliding motion, A-lines, B-lines, consolidation, effusion, and the presence of barcode signs were evaluated individually. Age, sex, comorbid diseases, other radiological examination findings, laboratory findings, final clinical diagnosis, and hospitalization-discharge status of the patients were recorded. RESULTS: When a correct diagnosis of pneumonia has been analyzed for imaging techniques, the diagnostic rate of chest radiography was 83.3%, CT was 100.0%, and USG was 66.6%. The correct diagnostic rate of chest radiography was 94.5%; CT and USG were 100.0%. The correct diagnosis of pulmonary edema on chest radiography was 94.5%; CT and USG were 100.0%. While the correct diagnosis of pleural effusion on chest radiography and CT was 100.0%, it was 92.3% in USG imaging. Finally, CT and USG imaging performed better than chest radiography in patients with pneumothorax (chest radiography 80.0%, CT and USG 100%). CONCLUSION: USG imaging could be preferred in the diagnosis of pneumonia, pulmonary edema, pleural effusion, pneumothorax, pulmonary embolism, and differential diagnosis at the emergency service.

Analysis of postoperative emergency admission and hospitalization of patients who underwent bariatric surgery: A single-center experience.

BACKGROUND: Bariatric surgery is a treatment with a low risk of complications that is becoming common in obesity treatment. OBJECTIVE: The aim of this study is to evaluate postoperative visits to the emergency department by patients who underwent bariatric surgery and to investigate what postoperative conditions are encountered in these patients and what can be done to prevent emergency room admission and hospitalization. SETTING: University Hospital. METHODS: The study included 394 patients aged 18 years underwent bariatric surgery for obesity. Emergency department (ED) admissions and diagnoses of patients who underwent bariatric surgery were analyzed in two groups, surgery-related and surgery-unrelated. RESULTS: It was found that 22% (n: 87) of patients visited the ED at least once; 4.8% (n: 19) of them were hospitalized; and 78.1% (n: 68) of 87 patients did not need to be hospitalized. Low preoperative iron, folic acid, and ferritin levels increase the number of visits to ED with a bariatric surgery-related complaint, urinary tract infection was the most common diagnosis and did not require hospitalization; the most common diagnosis of hospitalized patients was gastrointestinal perforation, pulmonary embolism, intra-abdominal abscess. CONCLUSION: Despite the low risk of complications, bariatric surgery is a surgery associated with a high number of preventable postoperative emergency visits. ED visits can be reduced by calling these patients for more frequent outpatient check-ups, providing intravenous hydration therapy in outpatient clinics and, if necessary, providing prescribed treatment.

The relationship between infarct volume and high sensitivity troponin I level in patients diagnosed with ischemic stroke.

BACKGROUND: Various biomarkers and clinical variables are used to determine the probability risk, diagnosis, and the prognosis of acute ischemic stroke, but effective markers are still warranted. AIM: We aimed to determine the effectiveness of Hs-cTnI levels to predict the prognosis of AIS. METHODS: This study was planned as a retrospective observational study. Patients with available data and over 18 years old were included in the study. Diffusion magnetic resonance images were evaluated by a senior radiologist and the infarct size was calculated. RESULTS: We included 110 (54.2%) males and 93 (45.8%) females; a total of 203 patients with a mean age of 68.9 were included in the present study. Patients were divided into two groups according to the cut-off level of Hs-troponin-I (group I: lower than 8.5 mg/dL; group 2: higher than 8.5 mg/dL). These two groups were compared for mortality and infarct volume. Infarct volume and the mortality ratio of the group 2 was significantly higher [p = 0.041, U = 4294.5, LV = 6.5 (IQR = 1.8-25.4)]. CONCLUSIONS: Hs-troponin I may be an effective biomarker in predicting the prognosis of patients with acute ischemic stroke. Multicenter comprehensive prospective studies are warranted to obtain stronger results.

The Role of Procalcitonin in Predicting Necessity of Antivenom Administration and Clinical Severity in Snake Bites.

One of the most important steps for preventing deaths due to snake bites is to administer snake antivenom to the eligible patients in a swift manner. In our study, we aimed to investigate whether procalcitonin is useful for predicting the clinical severity and the necessity of antivenom therapy at the early stages in patients presenting with snake bite. A total of 78 patients over the age of 18 who applied to the emergency department within the first 24 hours were included in this retrospective cross-sectional study. Age and sex of patients, severity of snake bites, total antivenom vials administered, observation periods and outcomes were recorded. Patients were graded according to their clinical severity after the snake bite. Procalcitonin, complete blood count and biochemical parameters of the patients were recorded. According to their clinical severity, the patients' grades were as follows: 21 (26.9%) patients were grade 0; 21 patients (26.9%) were grade 1; 16 patients (20.5%) were grade 2; and 20 patients (25.6%) were grade 3. Snake antivenom was administered to 57 (73.1%) patients. There was a statistically significant difference between procalcitonin levels of patients in respect to their grade (P < 0.001). Sensitivity and specificity of procalcitonin levels of 13.45 and above were 100% and 100% respectively, both for the need of antivenom administration and for the blister formation in the patients. According to our study, we believe that elevated procalcitonin levels should alert the clinicians for possible blister formation, higher clinical severity, and increased requirement for antivenom administration.
