Time Point

Background Neuron-specific enolase (NSE) is released into serum when nerve cells are damaged, and the levels thereof are used to determine neurological prognosis in patients who have suffered cardiac arrest or stroke. Delayed neuropsychiatric sequelae (DNS), a major complication of carbon monoxide poisoning (COP), can be caused by inflammatory response which is a mechanism of neuronal injury in cardiac arrest and stroke. NSE is known as a predictor of neurological prognosis in ischemic brain injury after cardiac arrest, and it is also reported as a predictor of DNS in acute COP. When serum NSE is measured serially in cardiac arrest patients, the best time to predict neurological prognosis is known at 48–72 h, but there are no studies analyzing serial serum NSE in acute COP. Thus, we explored whether serum NSE levels measured three times at 24 h intervals after COP predicted the development of DNS. Methods This prospective observational study was conducted on patients treated for COP from May 2018 to April 2020 in a tertiary care hospital in Korea. Neuron-specific enolase levels were assessed 24, 48, and 72 h after presentation at hospital. We used logistic regression to explore the association between NSE levels and DNS development. Results The NSE level was highest at 48 h, and the difference between the DNS group and the non-DNS group was greatest on the same time point. On multivariable logistic regression analysis, the NSE level at 48 h of >20.98 ng/mL (odds ratio [OR], 3.570; 95% confidence interval [CI], 1.412–9.026; P = .007) and the initial Glasgow Coma Scale (GCS) score of <9 (OR, 4.559; 95% CI, 1.658–0.12.540; P = .003) was statistically significant for DNS development. Conclusion Early identification of those who will experience DNS in acute COP patients is clinically important for deciding treatment. In this study, we revealed that NSE level of >20.98 ng/mL at 48 h time point can be used as an independent predictor of DNS (OR, 3.570; 95% CI, 1.412–9.026; P = .007; AUC, 0.648).

Delayed onset of neuropsychiatric symptoms after apparent recovery from acute carbon monoxide (CO) poisoning has been described as delayed neuropsychiatric sequelae (DNS). To date, there have been no studies on the utility of serum neuron-specific enolase (NSE), a marker of neuronal cell damage, as a predictive marker of DNS in acute CO poisoning. This retrospective observational study was performed on adult patients with acute CO poisoning consecutively treated over a 9-month period. Serum NSE was measured after emergency department arrival, and patients were divided into two groups. The DNS group comprised patients with delayed sequelae, while the non-DNS group included patients with none of these sequelae. A total of 98 patients with acute CO poisoning were enrolled in this study. DNS developed in eight patients. The median NSE value was significantly higher in the DNS group than in the non-DNS group. There was a statistical difference between the non-DNS group and the DNS group in terms of CO exposure time, Glasgow Coma Scale (GCS), loss of consciousness, creatinine kinase, and troponin I. GCS and NSE were the early predictors of development of DNS. The area under the curve according to the receiver operating characteristic curves of GCS, serum NSE, and GCS combined with serum NSE were 0.922, 0.836, and 0.969, respectively. In conclusion, initial GCS and NSE served as early predictors of development of DNS. Also, NSE might be a useful additional parameter that could improve the prediction accuracy of initial GCS.

Objectives: Holmium: YAG laser has gained its popularity throughout the years and is used to treat sialolithiasis, which helps to overcome the limitations of traditional sialendoscopic lithotripsy for larger-sized salivary stones. However, little information is available regarding factors predicting the success rate of Holmium: YAG laser intraductal lithotripsy. The purpose of this study is to investigate the factors affecting the success rates of Holmium: YAG laser lithotripsy for salivary stones treatment in a tertiary care hospital. Methods: A retrospective study conducted in patients receiving sialolithiasis surgery under sialendoscopy from May 2013 to March 2015 at Mackay Memorial Hospital, Taiwan. Data on various factors, including patients’ age, gender, glands, size of largest stone, multiple stones (≥2 stones), location of the stone (distal duct, middle duct, proximal duct, and hilum), and operative time. The success of the surgery defined as patients without any complaints such as swelling or tenderness. Logistic regression and Fisher exact tests were employed to examine these factors on the success rate. Results: Fifty-four patients who received sialendoscopy surgery with a mean age of 35.74 years old recruited. Logistic regression identified the operation time exceeding 210 minutes showed 23.497 folds higher odd ratio of having a result of operation failure ( P < .05). Conclusion: The prolonged operation time is the sole independent factor affecting the successful outcome for salivary gland intraductal laser lithotripsy. We recommend operative time be no more than 210 minutes to increase the success rate in salivary gland Holmium: YAG laser intraductal lithotripsy.

Carbon monoxide poisoning during pregnancy is a rare and potentially serious condition. Fetal complications are uncommon, related to anoxic lesions. The severity of these complications does not depend on the level of maternal COHb. We report the case of a 22-year-old pregnant woman who at 30 weeks of gestation had carbon monoxide poisoning secondary to a fire in her home, complicated by cardiac arrest and severe fetal damage. The child had not brain damage, but presented bladder lesions not previously described, with urinary ascites complicating megacystis.

Delayed Neuropsychiatric Sequelae

Objective. Delayed neuropsychiatric sequelae (DNS) are serious complications of carbon monoxide (CO) poisoning that adversely affect poisoned patients’ quality of life as well as socioeconomic status. This study aimed to determine clinical predictors of DNS in patients with CO poisoning. Methods. This retrospective study included all CO-poisoned patients admitted to the emergency department (ED) of Linkou Chang Gung Memorial Hospital in Taiwan from 1 January 2009 to 31 December 2015. The medical records of all patients with CO poisoning were carefully reviewed, and relevant data were abstracted into a standardised form. Univariate and multivariate logistic regression models were used to identify predictors of DNS after CO poisoning. Receiver operating characteristic (ROC) curve analysis was used to determine the ideal cut-off value for continuous variables that predict the development of DNS. Results. A total of 760 patients with CO poisoning were identified during the study period. Among them, 466 were eligible for the analysis of predictors of DNS. In multivariate analysis, Glasgow Coma Scale <9 (odds ratio [OR], 2.74; 95% confidence interval [CI], 1.21–6.21), transient loss of consciousness (OR, 3.59; 95% CI, 1.31–9.79), longer duration from CO exposure to ED presentation (OR, 1.05; 95% CI, 1.03–1.08), and corrected QT (QTc) prolongation (OR, 2.61; 95% CI, 1.21–5.61) were found to be associated with a higher risk of DNS. The area under the ROC curve (AUC) for QTc interval measured within 6 h after exposure best predicted the development of DNS, with a result of 0.729 (95% CI 0.660–0.791). Moreover, the best cut-off value of the QTc interval was 471 ms, with a sensitivity of 53.3% and a specificity of 85.1%. Conclusions. We identified several potential predictors of DNS following CO poisoning. Among them, QTc prolongation found within 6 h after exposure is a novel predictor of DNS, which may be helpful in the future care of patients with CO poisoning.

Background: Hemangioblastomas are benign neoplasms that consist of stromal cells and small blood vessels. They are highly vascular tumors and can arise throughout the central nervous system. This study aims to provide an overview of our experience with this rare tumor’s presentation, radiology, histopathology, and outcomes as literature regarding this pathology is sparse from our country. Methods: The study is a retrospective review of cases that were histopathology proven cases of spinal cord hemangioblastomas. The clinical characteristics of these patients were examined, and their presentation was recorded. The radiology was also reviewed to describe classic appearance on magnetic resonance imaging. A detailed review of immunohistochemistry was also performed and outcome was described. Results: A total of 25 cases of spinal hemangioblastomas were found in our records in the period of 2001–2019. There were 20 males (80%) and only 5 female patients (20%). Gross tumor fragments ranged in size from 0.24 cm2 to 10.5 cm2 (mean 3.28 ± 2.65). Histologically, tumor was composed of nests of large stromal cells with clear to vacuolated cytoplasm separated by thin-walled capillaries. Focal intratumoral hemorrhage was noted. No significant cytological atypia or mitotic figures were noted. Immunohistochemical stains were performed to confirm the diagnosis and exclude other tumors. Inhibin was tested in 20 cases and it was positive in 16 cases (80%). Neuron-specific enolase was positive in 6/8 cases. Cluster of differentiation (CD) CD68 was positive in 6/6 cases and vimentin in 4/4 cases. Glial fibrillary acidic protein (GFAP) and epithelial membrane antigen were performed in 14 and 8 cases, respectively, and all were negative. Cytokeratin AE1/AE3 was negative in 13/13 cases. CD34 highlighted vasculature in the 8 cases in which it was performed and was negative in tumor cells. Follow-up was available in 17 out of 25 cases and ranged from 12 months to 216 months (mean 61.8 ± 60.6 months). Recurrence occurred in 2 out of 17 (11.7%) patients for whom follow-up information was available. Conclusion: Our experience shows that spinal cord hemangioblastomas can be surgically removed in most cases with a low risk of recurrence. Most patients in our study were male and unlike other studies, none of our cases showed GFAP positivity.

Abstract Background Discriminating Mycoplasma pneumoniae (MP) from Streptococcus pneumoniae (SP) and viral etiologies of community-acquired pneumonia (CAP) is challenging but has important implications regarding empiric antibiotic therapy. We investigated patient parameters upon hospital admission to predict MP infection. Methods All patients hospitalized in a tertiary care hospital between 2013 and 2017 for CAP with a confirmed etiology were analyzed using logistic regression analyses and area under the receiver operator characteristics (ROC) curves (AUC) for associations between demographic, clinical and laboratory features and the causative pathogen. Results We analyzed 568 patients with CAP, including 47 (8%) with MP; 152 (27%) with SP and 369 (65%) with influenza or other viruses. Comparing MP and SP by multivariate logistic regression analysis, younger age (odds ration [OR] 0.56 per 10 years, 95% CI 0.42–0.73), a lower neutrophil/lymphocyte ratio (OR 0.9, 0.82–0.99) and an elevated C-reactive protein/procalcitonin (CRP/PCT) ratio (OR 15.04 [5.23–43.26] for a 400 mg/μg cut-off) independently predicted MP. With a ROC curve AUC of 0.91 (0.80 for the >400 mg/μg cutoff), the CRP/PCT ratio was the strongest predictor of MP vs. SP. The discriminatory value resulted from significantly lower PCT values (p < 0.001) for MP, while CRP was high in both groups (p = 0.057). Comparing MP and viral infections showed similar results with again the CRP/PCT ratio providing the best information (AUC 0.83; OR 5.55 for the >400 mg/μg cutoff, 2.26–13.64). Conclusions In patients hospitalized with CAP, a high admission CRP/PCT ratio predicts M. pneumoniae infection and may improve empiric management.

ABSTRACT INTRODUCTION: Gallstone disease (GSD) represents a significant burden for health-care systems worldwide and is one of the most common disorders among patients presenting to emergency rooms with abdominal discomfort. This study was aimed to know the association of biochemical parameters and development of GSD. MATERIALS AND METHODS: We conducted a case–control study from January 2013 to December 2013 among patients attending outpatient department of general surgery at a tertiary care hospital of Delhi, North India; we recruited 120 cases and the same number of controls in the study. Data collection for both cases and controls was done on a self-designed pretested interview schedule and all the patients were investigated for relevant biochemical parameters. Logistic regression was used for univariate and multivariate analyses to find out different correlates and analyze the independent effects of these correlates on GSD. RESULTS: We have included 120 cases and the same number of age- and sex-matched controls in the study and final analysis. Almost 70% of the cases were females and 30% were males. In multivariate logistic regression, we have found maximum significant association with serum total cholesterol (odds ratio [OR]: 1.013, confidence interval [CI]: 1.003–1.024, P = 0.041) followed by low-density lipoprotein (LDL) cholesterol (OR: 1.017, CI: 1.001–1.034, P = 0.04) and triglycerides (OR: 1.009, CI: 1.001–1.018, P = 0.049). Fasting blood sugar (P = 0.18), high-density lipoprotein cholesterol (P = 0.07), aspartate transaminase (P = 0.21), alanine transaminase (P = 0.29), and total bilirubin (P = 0.13) were not found to be independently associated with GSD. Conclusions: Biochemical parameters such as plasma total cholesterol, triglycerides, and LDL cholesterol level were independently associated with GSD.
