Purpose: : This study aimed to determine the effectiveness of end-of-life care debriefing as an intervention to reduce moral distress among intensive care unit (ICU) nurses after end-of-life care. Methods: : This quasiexperimental study included 104 nurses (46 in the control group and 58 in the intervention group) working in three medical ICUs and two surgical ICUs. The data collection period was from September 1, 2017, to January 31, 2018, and end-of-life care debriefing in the intervention group was implemented over three months. Debriefings were conducted in groups or individually, with eight people participating in three or more debriefings. Comparisons of end-of-life care stress, end-of-life care attitudes, and wellness between the two groups were performed using an ANCOVA. Satisfaction with the debriefing was analyzed using descriptive statistics. Results: : End-of-life care stress and wellness did not differ between the groups, but there was a significant difference in end-of-life care attitudes. Overall, 50% of the participants were satisfied with the debriefing. Conclusion : Based on the finding that end-of-life care debriefing has a positive impact on ICU nurses’ attitudes toward end-of-life care, it can be used as an effective measure to reduce nurses’ moral distress. An institutional debriefing system should be established and operationalized.

Acute ascending hemorrhagic longitudinally extensive transverse myelitis is a rare inflammatory demyelinating disorder, which invades several vertebral segments and progresses rapidly and manifests severe symptoms. We present a case of acute necrotizing myelitis associated with COVID-19 infection. A 10-year-old female, with no previous medical history and no prior administration of COVID-19 vaccination, contracted COVID-19 in early April 2022. Two weeks later, she suffered from severe posterior neck pain and also presented with motor weakness and numbness in both lower extremities, making it difficult to walk independently and spontaneously void urine. Initial spinal cord MR showed longitudinally segmental extensive T2 hyperintensities. Cerebrospinal fluid (CSF) analysis revealed elevated red blood cell, normal white blood cell, and elevated protein levels and absence of oligoclonal bands. CSF culture and viral polymerase chain reaction were negative. Autoimmune work-up was negative. She was started on intravenous methylprednisolone 1g/day for 5 days and immunoglobulin (Ig) 2 g/kg for 5 days. She was also treated with six courses of therapeutic plasma exchange. Nevertheless, her pain and motor weakness persisted. She eventually developed respiratory failure. Follow-up MR presented a newly noted small hemorrhagic component. She was consequently treated with two additional courses of methylprednisolone and Ig. At 6-months follow-up, neurological examination showed improvement with normal sensory function and motor grade IV function in both upper extremities. We present the case of acute necrotizing myelitis associated with COVID-19 infection. Multiple courses of methylprednisolone and Ig showed mild improvement in motor and sensory function. However, poor prognosis was unavoidable due to rapid progression of the disease.

Objective: : Electrooculography (EOG) records eyeball movements as changes in the potential difference between the negatively charged retina and the positively charged cornea. We aimed to investigate whether reliable EOG waveforms can be evoked by electrical stimulation of the oculomotor and abducens nerves during skull base surgery. Methods: : We retrospectively reviewed the records of 18 patients who had undergone a skull base tumor surgery using EOG (11 craniotomies and seven endonasal endoscopic surgeries). Stimulation was performed at 5 Hz with a stimulus duration of 200 μs and an intensity of 0.1–5 mA using a concentric bipolar probe. Recording electrodes were placed on the upper (active) and lower (reference) eyelids, and on the outer corners of both eyes; the active electrode was placed on the contralateral side. Results: : Reproducibly triggered EOG waveforms were observed in all cases. Electrical stimulation of cranial nerves (CNs) III and VI elicited positive waveforms and negative waveforms, respectively, in the horizontal recording. The median latencies were 3.1 and 0.5 ms for craniotomies and endonasal endoscopic surgeries, respectively (p=0.007). Additionally, the median amplitudes were 33.7 and 46.4 μV for craniotomies and endonasal endoscopic surgeries, respectively (p=0.40). Conclusion : This study showed reliably triggered EOG waveforms with stimulation of CNs III and VI during skull base surgery. The latency was different according to the point of stimulation and thus predictable. As EOG is noninvasive and relatively easy to perform, it can be used to identify the ocular motor nerves during surgeries as an alternative of electromyography.

PURPOSE: No guidelines exist detailing when to implement a temporary ileostomy closure in the setting of adjuvant chemotherapy following sphincter-saving surgery for rectal cancer. The aim of this study was to evaluate the clinical and oncological outcomes of ileostomy closure during adjuvant chemotherapy in patients with curative resection of rectal cancer. METHODS: This retrospective study investigated 220 patients with rectal cancer undergoing sphincter-saving surgery with protective loop ileostomy from January 2007 to August 2016. Patients were divided into 2 groups: group 1 (n = 161) who underwent stoma closure during adjuvant chemotherapy and group 2 (n = 59) who underwent stoma closure after adjuvant chemotherapy. RESULTS: No significant differences were observed in operative time, blood loss, postoperative hospital stay, or postoperative complications in ileostomy closure between the 2 groups. No difference in overall survival (P = 0.959) or disease-free survival (P = 0.114) was observed between the 2 groups. CONCLUSION: Ileostomy closure during adjuvant chemotherapy was clinically safe, and interruption of chemotherapy due to ileostomy closure did not change oncologic outcomes.

The purpose of this study was to investigate the speech characteristics and speech therapy of Parkinson disease (PD). This study selected 28 papers published in Korea from 1998 to 2018 after searching the terms ‘Parkinson voice’ and ‘Parkinson speech therapy.’ Literature review had been conducted in the two aspects of speech characteristics and speech therapy. The speech characteristics were divided into respiration, phonation, articulation, prosody, vowel production, and voice questionnaire. Speech therapy was divided into Lee Sliverman voice treatment (LSVT) and other voice therapy. PD patients did not differ in respiration function compared to normal elderly people, but their speech and articulation function were poorer. There was also a difference in the speech rate, frequency of pause, and accuracy of vowel production compared with normal elderly people. PD had a lower VHI score and their voice related quality of life was a little poorer. The LSVT was typically used in speech therapy for PD. The methods of speech therapy for PD have been shown to improve respiration and phonation. It is necessary to establish voice norms in PD patients and develop effective speech therapy in the following study.

Arterial steal syndrome is a rare but serious complication that disrupts antegrade flow distal to an arteriovenous fistula (AVF) because of excess blood flow through the AVF. A 65-year-old woman with diabetes mellitus and undergoing hemodialysis was admitted for coldness and pain in the right hand ipsilateral to an AVF. AVF stenosis had developed 6 months after an upper-arm AVF operation. These manifestations developed 2 days after a successful radiological intervention for a stenotic lesion in the AVF, which became worse until the skin on her hand ulcerated. The symptoms became aggravated, particularly during dialysis. Fistulography revealed that the AVF anastomosis site was patent but blood flow toward the forearm had decreased severely. Arterial steal syndrome developing after percutaneous angioplasty for an AVF stenosis was suspected, and the AVF was ligated, which resolved the hand pain and ulceration.

Idiopathic acute eosinophilic pneumonia (IAEP), characterized by acute febrile respiratory failure associated with diffuse radiographic infiltrates and pulmonary eosinophilia, is rarely reported in children. Diagnosis is based on an association of characteristic features including acute respiratory failure with fever, bilateral infiltrates on the chest X-ray, severe hypoxemia and bronchoalveolar lavage fluid >25% eosinophils or a predominant eosinophilic infiltrate in lung biopsies in the absence of any identifiable etiology. We present a 14-month-old girl who was admitted to our pediatric intensive care unit because of acute respiratory distress. She had a fever, dry cough, and progressive dyspnea for 1 day. Chest X-ray showed multifocal consolidations, increased interstitial markings, parenchymal emphysema and pneumothorax. IAEP was confirmed by marked pulmonary infiltrates of eosinophils in the lung biopsy specimen. Most known causes of acute eosinophilic pneumonia, such as exposure to causative drugs, toxins, second-hand smoking and infections were excluded. Her symptoms were resolved quickly after corticosteroid therapy.

PURPOSE: Cough and wheezing are the most common respiratory symptoms in children. Recently, the cough-holter monitoring has been used to estimate the frequency and intensity of cough and wheezing, objectively. In this study, we aimed to evaluate the validity of cough-holter monitoring for the objective assessment of cough and wheezing in the hospitalized children with respiratory symptoms. METHODS: Cough-holter monitoring was performed in 59 children who suffered from cough and/or wheezing. We obtained the information on the frequency and intensity of cough and wheezing from the parents, a pediatrician, and cough-holter monitoring. Visual Analogue Scale (VAS) scores were taken by parents, and the pediatrician estimated the wheezing score by using a stethoscope. We assessed a relationship between the VAS scores, wheezing score, and cough-holter monitoring data. RESULTS: The frequencies and intensities of cough correlated positively with the VAS scores (r=0.301, P=0.032; and r=0.540, P=0.001, respectively) and the frequencies and intensities of wheezing also correlated positively with the Wheezing scores. (r=0.335, P=0.011; and r=0.457, P=0.001, respectively) The wheezing intensity did not correlate with the Wheezing score in wheezing children. (r=0.321, P=0.089) CONCLUSION: Cough-holter monitoring correlated positively with the VAS scores and the wheezing scores. Cough-holter monitoring appears to be a useful objective assessment tool for the children who have suffered from cough and/or wheezing.

PURPOSE: The measurement of fraction of nitric oxide (FeNO) is a noticeable tool that reflects airway inflammation in asthmatic patients. We wanted to find out the relationship between pulmonary function, bronchial hyperresponsiveness (AHR), blood eosinophilic inflammatory markers and FeNO level before and after methacholine bronchoprovocation test in asthmatic patients. METHODS: Fifty-five children, who visited the Allergy Clinic of Korea University Anam Hospital from March 2011 to February 2012, due to asthmatic symptoms, such as history of episodic wheezing or dyspnea during the previous year and resolved after using bronchodilators, were enrolled. We performed the baseline pulmonary function and methacholine bronchoprovocation test in the enrolled patients. Blood eosinophil counts and blood eosinophil cationic protein (ECP) were measured. FeNO levels were measured before and after the methacholine bronchoprovocation test. RESULTS: The mean FeNO levels (36.3 ppb) fell after methacholine bronchoprovocation test (25.7 ppb). Forced expiratory volume in one second (FEV1) %pred inversely correlated both with FeNO level before (R2=0.07, P=0.029) and after (R2=0.059, P=0.01) methacholine bronchoprovocation test. The provocative concentration, causing a 20% decrease in FEV1 to methacholine (methacholine PC20) inversely correlated both with FeNO levels before (R2=0.086, P=0.001) and after (R2=0.141, P=0.001) the challenge. FeNO level measured at bronchoconstriction state significantly correlated with blood eosinophil counts (R2=0.112, P=0.028). Serum ECP levels correlated FeNO level, neither before nor after bronchoprovocation. CONCLUSION: The baseline FeNO levels were higher in asthmatic children. However, FeNO levels rather decreased after methacholine induced bronchoconstriction. Repeated spirometry maneuver was considered to have an effect on reducing FeNO levels. FeNO correlated with pulmonary function, airway AHR and blood eosinophil counts.

PURPOSE: The aim of this study was to investigate bronchodilator responsiveness (BDR) following methacholine-induced bronchoconstriction and to determine differences in BDR according to clinical parameters in children with asthma. METHODS: The methacholine challenge test was performed in 145 children with mild to moderate asthma, and the provocative concentration causing a 20% decline in FEV1 (PC20) was determined. Immediately after the challenge test, patients were asked to inhale short-acting beta2-agonists (SABAs) to achieve BDR, which was assessed as the change in FEV1% predictedx100/post-methacholine FEV1% predicted. For each subject, the asthma medication, blood eosinophil count, serum total IgE, serum eosinophil cationic protein level, and skin prick test result were assessed. RESULTS: The FEV1 (mean+/-SD) values of the 145 patients were 90.5+/-10.9% predicted, 64.2+/-11.5% predicted, and 86.2+/-11.2% predicted before and after methacholine inhalation, and following the administration of a SABA, respectively. The BDR did not differ significantly according to asthma medication, age, or gender. However, BDR in the atopy group (37.4+/-17.7%) was significantly higher than that in the non-atopy group (30.5+/-10.7%; P=0.037). Patients with blood eosinophilia (38.6+/-18.1%) displayed increased BDR compared with patients without eosinophilia (32.0+/-13.8%; P=0.037). CONCLUSIONS: In children with mild to moderate asthma, the responsiveness to short-acting bronchodilators after methacholine-induced bronchoconstriction was not related to asthma medication, but was higher in children with atopy and/or peripheral blood eosinophilia.
