Background: It is important to communicate accurately in the emergency department. Due to COVID-19 pandemic, a mask is mandatory to protect medical staffs and patients from infectious diseases, and the mask is known to disturb speech intelligibility. The objective of this study is to find out if a transparent mask can affect communication. Methods: : We conducted a randomized pre- and post-test trial with 40 participants in a real emergency room environment. The reader puts on a mask and read aloud sentences which are frequently used between medical staffs and patients or among medical staffs. The type of mask was randomly assigned to the reader which was transparent or non-transparent. Frequently used 5 sentences between medical staffs and patients and 5 sentences among medical staffs from prepared 100 sentences were randomly selected and recited. Participants were told to write down the sentences they heard. Each sentence written down was graded 0 or 1. After writing down 10 sentences, reader puts on another type of mask and the same experiment was done. The order of transparenton-transparent mask was randomly allocated to each participant. Results: : In frequently used sentences between medical staffs and patient, average score with a transparent mask was 4.88, and with a non-transparent mask was 4.50(p=0.001). In frequently used sentences among medical staffs, average score with a transparent was 4.77, and with a non-transparent mask was 4.05(p<0.001). Conclusions This study showed the transparent mask improves speech intelligibility when communicating in an emergency room.

Vitamin B12 deficiency results in the occurrence of systemic diseases in our nervous system. One of the most common manifestations of Vitamin B12 deficiency is subacute combined degeneration (SCD), which is characterized by paralysis and sensory changes of limbs, and disturbance of gait and position sense. SCD can be caused by the abuse of Happy Balloon, which comprises nitrous oxide and is used as a party hallucinogen. Diagnosis of SCD is achieved by combining the clinical symptoms, laboratory study, electrophysiological study and imaging findings. However, neurological symptoms observed during laboratory examinations are insufficient to diagnose SCD without the characteristic magnetic resonance imaging (MRI) findings. This is due to ambiguity of the symptoms and delayed report time of laboratory results in the emergency department. The ‘Inverted V sign’, observed towards the rear of the cervical and thoracic spine in T2 emphasis MRI images, is the most prominent finding of SCD. In most cases, the T1 image shows the same signal strength as the surrounding tissue. In the current report, we present an SCD case with an enhanced T1 phase of the MRI.

Purpose: : Since the era of COVID-19, face-to-face contact has been reduced to prevent the spread of infectious diseases around the world, and hospitals are applying various methods to prevent the spread of infection. However, when writing a consent form essential during the treatment process, it had to be done face-to-face. We developed a non-face-to-face communication device to enable real-time consent writing. This study aims to evaluate the usefulness of the non-face-to-face communication device when writing a consent form. Methods: : From December 28, 2021 to February 2, 2022, electronic medical records of patients visited the severance hospital emergency center and had a central venous catheter inserted were collected retrospectively. There were 56 consent forms included in the study, 43 face-to-face and 13 non-face-to-face. We checked the difference between the details explained in the non-face-to-face consent form and the face-to-face by the average score and the explanation of each item. The score was measured from a minimum of 0 points to a maximum of 13 points, with 1 point for explained items and 0 points for unexplained. Results: : The average score for the face-to-face consent form was 4.3, and for the non-face-to-face was 3.0 (p=0.148). There was no significant difference in the explanation of each item. Conclusion : It was confirmed writing a consent form through the non-face-to-face communication device can perform a similar role compared to the face-to-face. It is expected unnecessary contact can be reduced by applying the device to hospital rooms, and enabling a non-face-to-face rounds system for new infectious diseases.

OBJECTIVES: The purpose of this study was to investigate the characteristics of attention, intellectual functioning and adaptation of girls with attention-deficit hyperactivity disorder (ADHD). METHODS: The scores of the ADHD Diagnostic System (ADS), the Korean Wechsler Intelligence Scale for Children-III (K-WISC-III) and the Korean Personality Inventory for Children (KPI-C) were compared between 26 girls with ADHD and 26 boys with ADHD. RESULTS: 1)There was no significant gender difference in the intellectual functioning, except for the picture completion subscale. 2) Compared to the boys, the girls responded more slowly on the ADS visual task. 3) The girls were rated higher by their parents for the depression and social relationship problems of the KPI-C. CONCLUSIONS: The results suggest that there are noticeable gender differences for the attention problems and social functioning of children with ADHD.

Background and Objectives: Some reports propose an increased risk of otitis media and hearing impairment after total laryngectomy. However, the incidence of otitis media following laryngectomy and the mechanism remain unclear. This study aimed to identify the incidence and risk factors of otitis media after total laryngectomy. Subjects and Methods: This retrospective cohort study assessed 77 patients who underwent total laryngectomy from 2010 to 2020 in a tertiary referral center. Serial imaging studies (computed tomography [CT], magnetic resonance imaging, and positron emission tomography-CT) were used to assess otitis media. Results: The study enrolled 58 patients (mean age, 67.0±7.7 years; male, 56 [96.6%]); nine (15.5%) underwent a gastrostomy tube (four preoperatively and five postoperatively). Otitis media was confirmed in seven (12.1%) patients. Gastrostomy tube insertion was the only significant risk factor for otitis media (p=0.012). Of the nine patients who underwent gastrostomy tube insertion, four developed otitis media; all four had the procedure after laryngectomy. Conclusions This study found an increased incidence of otitis media after total laryngectomy. Swallowing difficulties likely contribute to otitis media as it occurred more frequently in patients requiring postoperative gastrostomy tube insertion.

Merkel cell carcinoma is an extremely rare neuroendocrine neoplasm of the external auditory canal (EAC) skin, which requires wide excision and adjuvant radiation due to a high recurrence rate. In this report, we describe a case of Merkel cell carcinoma arising from the EAC which was successfully treated with endoscopic excision. A 32-years-old female patient with a history of papillary thyroid cancer was diagnosed with an EAC tumor incidentally. There was a erythematous papular lesion on the posterior EAC without any evidence of locoregional metastasis. The patient underwent endoscopic tumor resection under general anesthesia, and the final pathologic report confirmed the diagnosis of Merkel cell carcinoma. There was no clinical or radiographic evidence of recurrence or metastasis of Merkel cell tumor for 41 months after surgical resection alone.

Renovascular hypertension (RVHT) is a major cause of surgically correctable secondary hypertension. Refractory hypertension despite multiple antihypertensive drugs requires angioplasty, surgical revascularization, or even nephrectomy. Herein, we report a pediatric patient who had been treated with angioplasty, nephrectomy, and aortorenal bypass surgery for RVHT due to fibromuscular dysplasia and re-do endoaneurysmal graft replacement for a vein graft aneurysm. This case highlights the various treatment modalities for RVHT and the recurrent nature of the disease with a rare presentation of a vein graft aneurysm after aortorenal bypass.

Background: : Effective communication between doctors and patients is very important not only for diagnosis and treatment but also for building trust. Although teaching communication skills is very important in medical schools, there are limitations such as the number of students and the uncertainty of the patient population. Therefore, this study evaluates the effect of Fishbowl method to teach communication skills to medical students, which involves the medical students communicating with standardized patients in front of a large classroom and being observed by rest of the students. Methods: : This study involves 10 weeks of educating 126 fourth grade medical students and graduates. During this period, total 8 classes were taken by subjects, where each class lasts 2 hours and is conducted by observing treatments of the standardized patients on 14 clinical topics by randomly selected medical students and giving feedback on the communication skills of the selected medical students. The educational effect was evaluated based on the scores of the clinical performance examination before and after the classes. Results: : The scores assessed for medical history taking before and after the training are increased by 2.45 (p<0.001) and the scores for patient-doctor relationship is increased by 7.56 (p<0.001). Conclusions : It is expected to improve the communication skills of medical students by large scale lectures with standardized patients.

We present a case of persistent left superior vena cava, anomalous right pulmonary venous connection to the right-sided superior vena cava and sinus venosus atrial septal defect detected by computed tomography (CT) pulmonary angiography and echocardiography. These defects were surgically corrected using a double-patch technique. In fact, CT can provide anatomical information about a complex anomaly in the systemic and pulmonary vasculatures. Though modern imaging techniques are useful for detecting complex cardiovascular disease, careful echocardiographic examination should be performed to diagnose complex cardiac anomalies.
