Gastric trichobezoars are commonly observed in young women with trichotillomania and trichophagia. We encountered an 8-year-old girl who had trichotillomania and trichophagia with abdominal pain and a mass, which was diagnosed as a large gastric trichobezoar. On physical examination, a huge, firm nontender mobile mass was palpated in her epigastrium. An upper gastrointestinal series and abdominal computed tomography (CT) scan showed a large mass in the stomach. Endoscopic removal was tried but failed. Laparoscopic removal was therefore performed. The trichobezoar was successfully retrieved through a gastrotomy and removed through an extended umbilical trocar incision. This case demonstrates that laparoscopic removal of large gastric trichobezoars is feasible and safe without a large abdominal incision.

PURPOSE: Recently, several studies for immature granulocyte proportion (IG%) in patients with sepsis have revealed its association with diagnosis and prognosis of patients with sepsis. In this study, we enrolled patients with severe sepsis and septic shock and compared IG% with other biologic markers as a predictor of 28-day mortality. METHODS: This was a retrospective study for patients with severe sepsis and septic shock who were admitted to the emergency department of a tertiary care hospital for four-months. The IG% measured using Sysmex XE-2100 and other inflammatory markers, including C-reactive protein, lactate, and procalcitonin were evaluated and compared for 28-day mortality. RESULTS: A total of 85 patients with septic shock and 45 patients with severe sepsis were enrolled. In the non-survivors group (n=32, 24.6%), APACHE II score (p=0.017), use of continuous renal replacement therapy (CRRT) (p=0.002), and septic shock (p=0.009) were statistically higher compared with thesurvivors group. APACHE II score (Odd ratio [OR] 1.099, p=0.008) and IG% (> or =0.5%) (OR 3.568, p=0.036) predicted the 28-day mortality independently after adjusting SOFA score, septic shock,disseminated intravascular coagulopathy, use of CRRT, and gender. However, IG (> or =0.5%) had low specificity of 33.7% and positive predictive value (PPV) of 30.1% for 28-day mortality. CONCLUSION: IG% could be a useful biologic marker for prediction of 28-day mortality in patients with severe sepsis or septic shock. However, the limitation of low specificity and PPV must be considered in clinical use.

PURPOSE: There has been active research on anaphylaxis, but many study subjects are limited to patients registered with anaphylaxis codes. However, anaphylaxis codes tend to be underused. The aim of this study was to investigate the accuracy of anaphylaxis code registration and the clinical characteristics of accurate and inaccurate anaphylaxis registration in anaphylactic patients. METHODS: This retrospective study evaluated the medical records of adult patients who visited the university hospital emergency department between 2012 and 2016. The study subjects were divided into the groups with accurate and inaccurate anaphylaxis codes registered under anaphylaxis and other allergy-related codes and symptom-related codes, respectively. RESULTS: Among 211,486 patients, 618 (0.29%) had anaphylaxis. Of these, 161 and 457 were assigned to the accurate and inaccurate coding groups, respectively. The average age, transportation to the emergency department, past anaphylaxis history, cancer history, and the cause of anaphylaxis differed between the 2 groups. Cutaneous symptom manifested more frequently in the inaccurate coding group, while cardiovascular and neurologic symptoms were more frequently observed in the accurate group. Severe symptoms and non-alert consciousness were more common in the accurate group. Oxygen supply, intubation, and epinephrine were more commonly used as treatments for anaphylaxis in the accurate group. Anaphylactic patients with cardiovascular symptoms, severe symptoms, and epinephrine use were more likely to be accurately registered with anaphylaxis disease codes. CONCLUSIONS: In case of anaphylaxis, more patients were registered inaccurately under other allergy-related codes and symptom-related codes rather than accurately under anaphylaxis disease codes. Cardiovascular symptoms, severe symptoms, and epinephrine treatment were factors associated with accurate registration with anaphylaxis disease codes in patients with anaphylaxis.

PURPOSE:
This study was to investigate errors of death certificate (DC) issued for patients with trauma.
METHODS:
A retrospective review for DC issued after death related to trauma at a training hospital trauma center was conducted. Errors on DC were classified into major and minor errors depending on their influence on the process of selecting the cause of death (COD). All errors were compared depending on the place of issue of DC, medical doctors who wrote the DC, and the number of lines filled up for COD of DC.
RESULTS:
Of a total 140 DCs, average numbers of major and minor errors per DC were 0.8 and 3.7, respectively. There were a total of 2.8 errors for DCs issued at the emergency department (ED) and 5.4 errors for DCs issued beyond ED. The most common major error was more than one COD on a single line for DCs issued at the ED and incompatible casual relation between CODs for DCs issued beyond ED. The number of major errors was 0.5 for emergency physician and 0.8 for trauma surgeon and neurosurgeon. Total errors by the number of lines filled up for COD were the smallest (3.1) for two lines and the largest (6.0) for four lines.
CONCLUSIONS
Numbers of total errors and major errors on DCs related to trauma only were 4 and 0.8, respectively. As more CODs were written, more errors were found.

OBJECTIVE: This study was conducted to evaluate the concordance between the underlying causes of death (UCOD) on the death certificates written by three emergency physicians (EPs). We investigated errors on the death certificates committed by each EP.METHODS: This study included 106 patients issued a death certificate in the emergency department of an academic hospital. Three EPs reviewed the medical records retrospectively and completed 106 death certificates independently. The selection of the UCOD on the death certificates by each EP (EP-UCOD) was based on the general principle or selection rules. The gold standard UCOD (GS-UCOD) was determined for each patient by unanimous consent between three EPs. We also compared between the EP-UCOD and the GS-UCOD. In addition, we compared between UCODs of three EPs. The errors on the death certificates were investigated by each EP.RESULTS: The rates of concordance between EP-UCOD and the GS-UCOD were 86%, 81%, and 67% for EP-A, EP-B, and EP-C, respectively. The concordance rates between EP-A and EP-B were the highest overall percent agreement (0.783), and those between EP-A and EP-C were the lowest overall percent agreement (0.651). Although each EP had differences in the errors they committed, none of them listed the mode of dying as UCOD.CONCLUSION: This study confirmed that each EP wrote death certificates indicating different causes of death for the same decedents; however, the three EPs made fewer errors on the patients’ death certificates compared with those reported in previous studies.

PURPOSE: This study was conducted to investigate the frequency and clinical characteristics of anaphylaxis patients who are registered inaccurately with other disease codes. METHODS: Study subjects presenting at the emergency department (ED) were retrospectively collected using disease codes to search for anaphylaxis patients in a previous studies. The study group was divided into an accurate and inaccurate group according to whether disease codes were accurately registered as anaphylaxis codes. RESULTS: Among 266 anaphylaxis patients, 144 patients (54%) received inaccurate codes. Cancer was the most common comorbidity, and the radio-contrast media was the most common cause of anaphylaxis in the accurate group. Cutaneous and respiratory symptoms manifested more frequently in the inaccurate group, while cardiovascular and neurological symptoms were more frequent in the accurate group. Blood pressure was lower, and shock and non-alert consciousness were more common in the accurate group. Administration of intravenous fluid and epinephrine use were more frequent in the accurate group. Anaphylaxis patients with a history of cancer, shock, and epinephrine use were more likely to be registered as anaphylaxis codes accurately, but patients with respiratory symptoms were more likely to be registered with other disease codes. CONCLUSION: In cases of anaphylaxis, the frequency of inaccurately registered disease codes was higher than that of accurately registered codes. Anaphylaxis patients who were not treated with epinephrine at the ED who did not have a history of cancer, but had respiratory symptoms were at increased risk of being registered with disease codes other than anaphylaxis codes.

Therapeutic hypothermia (TH) improves the neurological outcome in patients after cardiac arrest and neonatal hypoxic brain injury. We studied the safety and feasibility of mild TH in patients with poor-grade subarachnoid hemorrhage (SAH) after successful treatment. Patients were allocated randomly to either the TH group (34.5°C) or control group after successful clipping or coil embolization. Eleven patients received TH for 48 hours followed by 48 hours of slow rewarming. Vasospasm, delayed cerebral ischemia (DCI), functional outcome, mortality, and safety profiles were compared between groups. We enrolled 22 patients with poor-grade SAH (Hunt & Hess Scale 4, 5 and modified Fisher Scale 3, 4). In the TH group, 10 of 11 (90.9%) patients had a core body temperature of < 36°C for > 95% of the 48-hour treatment period. Fewer patients in the TH than control group (n = 11, each) had symptomatic vasospasms (18.1% vs. 36.4%, respectively) and DCI (36.3% vs. 45.6%, respectively), but these differences were not statistically significant. At 3 months, 54.5% of the TH group had a good-to-moderate functional outcome (0–3 on the modified Rankin Scale [mRS]) compared with 9.0% in the control group (P = 0.089). Mortality at 1 month was 36.3% in the control group compared with 0.0% in the TH group (P = 0.090). Mild TH is feasible and can be safely used in patients with poor-grade SAH. Additionally, it may reduce the risk of vasospasm and DCI, improving the functional outcomes and reducing mortality. A larger randomized controlled trial is warranted.

PURPOSE: The aim of this study was to survey the accuracy of registration as anaphylaxis codes and the clinical characteristics of anaphylaxis registered correctly and incorrectly in pediatric anaphylaxis. METHODS: This study was conducted retrospectively using the medical records of patients under 15 years who visited a training hospital Emergency Department (ED) for 5 years. The study subjects were divided into the correct group (registered as anaphylaxis codes correctly) and the incorrect group (registered as other anaphylaxis related codes). RESULTS: Of the 133 patients, 14 belonged to the correct group and 119 to the incorrect group. The median age of the correct group was 9 years old and that of the incorrect group was 2 years old. Sex, transportation to the ED, elapsed time from exposure to ED arrival, past history of allergy, causes of anaphylaxis except drug, severity of symptom, mental status, and antihistamine use were not different between the 2 groups. Drugs as the cause of anaphylaxis and cardiovascular/neurologic symptoms were more common in the correct group. Gastrointestinal symptoms were more frequent in the incorrect group. Intravenous fluid, steroid, bronchodilator, and epinephrine were more commonly used as the treatment for anaphylaxis in the correct group. The pediatric patients treated with epinephrine tended to be registered anaphylaxis correctly. CONCLUSION: More patients were registered incorrectly as other anaphylaxis-related disease codes rather than correctly as the anaphylaxis disease codes in pediatric anaphylaxis. Epinephrine use was the associated factor for being registered correctly as the anaphylaxis disease codes in pediatric anaphylaxis.

Journal of Korean Medical Science 2021;36(36):e255-
Background:
Since the declaration of the coronavirus disease 2019 (COVID-19) pandemic, COVID-19 has affected the responses of emergency medical service (EMS) systems to cases of out-of-hospital cardiac arrest (OHCA). The purpose of this study was to identify the impact of the COVID-19 pandemic on EMS responses to and outcomes of adult OHCA in an area of South Korea.
Methods:
This was a retrospective observational study of adult OHCA patients attended by EMS providers comparing the EMS responses to and outcomes of adult OHCA during the COVID-19 pandemic to those during the pre-COVID-19 period. Propensity score matching was used to compare the survival rates, and logistic regression analysis was used to assess the impact of the COVID-19 pandemic on the survival of OHCA patients.
Results:
A total of 891 patients in the pre-COVID-19 group and 1,063 patients in the COVID-19 group were included in the final analysis. During the COVID-19 period, the EMS call time was shifted to a later time period (16:00–24:00, P < 0.001), and the presence of an initial shockable rhythm was increased (pre-COVID-19 vs. COVID-19, 7.97% vs. 11.95%, P = 0.004). The number of tracheal intubations decreased (5.27% vs. 1.22%, P < 0.001), and the use of mechanical chest compression devices (30.53% vs. 44.59%, P < 0.001) and EMS response time (median [quartile 1-quartile 3], 7 [5–10] vs. 8 [6–11], P < 0.001) increased. After propensity score matching, the survival at admission rate (22.52% vs. 18.24%, P = 0.025), survival to discharge rate (7.77% vs. 5.52%, P = 0.056), and favorable neurological outcome (5.97% vs. 3.49%, P < 0.001) decreased. In the propensity score matching analysis of the impact of COVID-19, odds ratios of 0.768 (95% confidence interval [CI], 0.592–0.995) for survival at admission and 0.693 (95% CI, 0.446–1.077) for survival to discharge were found.
Conclusion
During the COVID-19 period, there were significant changes in the EMS responses to OHCA. These changes are considered to be partly due to social distancing measures. As a result, the proportion of patients with an initial shockable rhythm in the COVID-19 period was greater than that in the pre-COVID-19 period, but the final survival rate and favorable neurological outcome were lower.
