Résumé
Objectives@#This study aimed to investigate the effectiveness and safety of combining psychostimulants and nonstimulants for patients under treatment for attention deficit hyperactivity disorder (ADHD). @*Methods@#The study included 96 patients aged 6–12 years who were diagnosed with ADHD, among whom 34 received combination pharmacotherapy, 32 received methylphenidate monotherapy, and 30 received atomoxetine monotherapy. Statistical analysis was conducted to compare treatment and adverse effects among groups and to analyze changes before and after combination pharmacotherapy.The difference between combination pharmacotherapy and monotherapy was investigated. Logistic regression analysis was used to identify the predictors of combination pharmacotherapy. @*Results@#No significant differences were observed between the groups in terms of age or pretreatment scores. The most common adverse effect experienced by 32% of patients in the combination pharmacotherapy group was decreased appetite. Clinical global impression-severity score decreased significantly after combination pharmacotherapy. All three groups showed significant clinical global impression-severity score improvements over time, with no significant differences among them. The predictive factors for combination pharmacotherapy included the Child Behavior Checklist total score internalizing subscale. @*Conclusion@#Combination pharmacotherapy with methylphenidate and atomoxetine is a relatively effective and safe option for patients with ADHD who do not respond to monotherapy.
Résumé
This study utilized cohort data, student lifestyle surveys, and mental health examination results from a medical school to investigate the impact of factors such as hometown, alcohol use, smoking, university life adaptation, and aptitude on academic failure, with mental health serving as a mediator. We analyzed data from 409 of the 549 incoming students at Keimyung University School of Medicine, excluding 140 individuals with missing data, from the academic years 2015 to 2021. Significant differences were found according to hometown in feelings of depression, suicidal tendencies, and internet addiction. There were also significant differences based on university life adaptation in feelings of depression, suicidal tendencies, and internet addiction, as well as significant differences according to academic aptitude in feelings of depression and internet addiction. Academic failure showed significant differences based on hometown, university life adaptation, and academic aptitude. Furthermore, students’ hometown had a complete mediating effect on academic failure together with feelings of depression, suicidal tendencies, and internet addiction. University life adaptation exhibited a complete mediating effect with suicidal tendencies and a partial mediating effect with feelings of depression and internet addiction. Academic aptitude demonstrated partial mediating effects on feelings of depression, suicidal tendencies, and internet addiction. Based on these results, we suggest establishing counseling programs tailored to the characteristics of medical students, and various programs for university life adaptation are necessary. There is also a need for diverse programs not only for clinical training, but also for different career paths.

Objective@#This study was performed to evaluate the efficacy and safety of lurasidone (160 mg/day) compared to quetiapine XR (QXR; 600 mg/day) in the treatment of acutely psychotic patients with schizophrenia. @*Methods@#Patients were randomly assigned to 6 weeks of double-blind treatment with lurasidone 160 mg/day (n=105) or QXR 600 mg/day (n=105). Primary efficacy measure was the change from baseline to week 6 in Positive and Negative Syndrome Scale (PANSS) total score and Clinical Global Impressions severity (CGI-S) score. Adverse events, body measurements, and laboratory parameters were assessed. @*Results@#Lurasidone demonstrated non-inferiority to QXR on the PANSS total score. Adjusted mean±standard error change at week 6 on the PANSS total score was -26.42±2.02 and -27.33±2.01 in the lurasidone and QXR group, respectively. The mean difference score was -0.91 (95% confidence interval -6.35–4.53). The lurasidone group showed a greater reduction in PANSS total and negative subscale on week 1 and a greater reduction in end-point CGI-S score compared to the QXR group. Body weight, body mass index, and waist circumference in the lurasidone group were reduced, with significantly lower mean change compared to QXR. Endpoint changes in glucose, cholesterol, triglycerides, and low-density lipoprotein levels were also significantly lower. The most common adverse drug reactions with lurasidone were akathisia and nausea. @*Conclusion@#Lurasidone 160 mg/day was found to be non-inferior to QXR 600 mg/day in the treatment of schizophrenia with comparable efficacy and tolerability. Adverse effects of lurasidone were generally tolerable, and beneficial effects on metabolic parameters can be expected.
Résumé
Patients frequently report that stress causes or exacerbates gastrointestinal (GI) symptoms, indicating a functional relationship between the brain and the GI tract. The brain and GI tract are closely related embryologically and functionally, interacting in various ways. The concept of the brain–gut axis was originally established in the 19th and early 20th centuries based on physiological observations and experiments conducted in animals and humans. In recent years, with the growing recognition that gut microbiota plays a vital role in human health and disease, this concept has been expanded to the brain–gut–microbiota axis. The brain influences the motility, secretion, and immunity of the GI tract, with consequent effects on the composition and function of the gut microbiota. On the other hand, gut microbiota plays an essential role in the development and function of the brain and enteric nervous system. Although knowledge of the mechanisms through which the gut microbiota influences distant brain function is incomplete, studies have demonstrated communication between these organs through the neuronal, immune, and endocrine systems. The brain–gut–microbiota axis is an essential aspect of the pathophysiology of functional GI disorders such as irritable bowel syndrome, and is also involved in other GI diseases, including inflammatory bowel disease. This review summarizes the evolving concept of the brain–gut–microbiota axis and its implications for GI diseases, providing clinicians with new knowledge to apply in clinical practice.
Résumé
Purpose@#The hand and forearm are the common points of contact and entry for electrical burns. Wounds from electrical burns can range from small to large and superficial to deep. High-voltage electrical burns result in skin and/or soft-tissue defects owing to progressive necrosis caused by intravascular thrombosis, causing complications in the coverage of electrical burns.Various coverage methods have been used for electrical burns on the hands and forearms. @*Methods@#Between 2017 and 2022, 61 patients were admitted for electrical burn treatment on the forearm and hand in our department; and 41 underwent coverage surgery. The range of motion was evaluated when feasible pre-and post-operatively. @*Results@#Among the 41 patients who underwent coverage surgery, 16 and 25 suffered deep second-and third-degree burns, respectively. Wounds of the remaining 20 healed with wound dressings as they were superficial or small. Patients with deep second-degree burns required various procedures, including full-thickness skin graft (FTSG), advanced local flap, split-thickness skin graft (STSG), and STSG with acellular dermal matrix (ADM). Procedures for patients with third-degree burns include an advanced local flap, STSG with ADM, FTSG, and other flap surgeries. All the wounds healed without major complications. @*Conclusion@#We successfully treated 41 burn wounds using different wound coverage methods, such as STSG or STSG with ADM for deep second-degree burns and flap surgery for third-degree burns. Moreover, in third-degree burns, STSG with ADM could substitute for flap surgery if flap surgery is not performed.
Résumé
Objectives@#This study was conducted to investigate the relationship between personality and decision making in the group of young male depression patients. @*Methods@#Eighty-four male depression patients were subjected to the following test: Beck’s Depression Inventory-II (BDI-II), and Beck’s Anxiety Inventory (BAI), Korean Wechsler Adult Intelligence Scale-IV (K-WAIS-IV), Minnesota Multiphasic Personality Inventory-2 (MMPI-2), Personality Assessment Inventory (PAI), Temperament Character Inventory-Revised Short version (TCI-RS), Delay Discounting Task (DDT), Game of Dice Task (GDT). Pearson’s correlation analysis was used to determine the association between DDT and GDT performance results and self-report examination. Multiple linear regression models were conducted to figure out the causal relationship between risky choice of GDT and the variables suspected of having a linear relationship. The collected data was analyzed using SPSS 21. @*Results@#PAI mania, borderline features, dominance and novelty seeking of TCI-RS were positively correlated with the number of risky choices of GDT. Full Scale Intelligence Quotient, BDI-II, BAI score had no significant correlation with DDT and GDT. There was also no correlation between DDT and GDT. @*Conclusions@#The results suggest that risk taking decision is related to personality traits such as novelty seeking, while inter-temporal choice is not related to personality aspects. It could be inferred that two different decision-making processes take place independently at different brain regions.
Résumé
Purpose@#Most of the causes of small bowel obstruction (SBO) in patients without a history of abdominal surgery are unclear at initial assessment. This study was conducted to identify the etiology and clinical characteristics of SBO in virgin abdomens and discuss the proper management. @*Methods@#A retrospective review involving operative cases of SBO from a single institute, which had no history of abdominal surgery, was conducted between January 2010 and December 2020. Clinical information, including radiological, operative, and pathologic findings, was investigated to determine the etiology of SBO. @*Results@#A total of 55 patients were included in this study, with a median age of 57 years and male sex (63.6%) constituting the majority. The most frequently reported symptoms were abdominal pain and nausea or vomiting. Neoplasm as an underlying cause accounted for 34.5% of the cases, of which 25.5% were malignant cases. In patients aged ≥60 years (n=23), small bowel neoplasms were the underlying cause in 12 (52.2%), of whom 9 (39.1%) were malignant cases. Adhesions and Crohn disease were more frequent in patients aged <60 years. Coherence between preoperative computed tomography scans and intraoperative findings was found in 63.6% of the cases. @*Conclusion@#There were various causes of surgical cases of SBO in virgin abdomens. In older patients, hidden malignancy should be considered as a possible cause of SBO in a virgin abdomen. Patients with symptoms of recurrent bowel obstruction who have no history of prior abdominal surgery require thorough medical history and close follow-up.
Résumé
Gastrointestinal (GI) prokinetic agents are drugs that increase GI motility and promote the movement of contents in the GI tract by amplifying and controlling the contraction of GI smooth muscle. Currently used prokinetics increase GI motility by acting as a dopamine D2 receptor antagonist (e.g., metoclopramide, domperidone, levosulpiride) and 5-HT4 receptor agonist (e.g., mosapride, prucalopride). Some prokinetics also have a cholinesterase inhibitory property (e.g., itopride), and herb-derived prokinetics (e.g., motilitone) affect multiple receptors. Depending on the type and distribution of receptors on which the prokinetics bind, the effect(s) may be regional or throughout the GI tract. Most prokinetics have been used for functional dyspepsia and gastroparesis because they mainly affect upper GI motility. However, prucalopride, a highly selective 5-HT4 receptor agonist, is used primarily to treat chronic constipation and pseudo-obstruction. Dopamine D2 receptor antagonists also inhibit the D2 receptor in the medulla oblongata chemoreceptor trigger zone; therefore, they can treat nausea and vomiting. However, short term use of dopamine D2 antagonists at an appropriate dose is recommended because of their potential for central nervous system side effects by penetrating the blood-brain barrier. It is necessary to know the mechanism of action, each clinical trial’s characteristics, and the side effects of prokinetics to obtain the best clinical outcomes. This article aims to summarize the results of clinical studies related to the impact of currently available prokinetic agents in Korea on GI motility.

Objectives@#:The purpose of this study was to investigate the effect of adult Attention-Deficit/Hyperactivity Disorder (ADHD) tendency on cognitive functions in the group of depression. @*Methods@#:117 male patients with depression (51 with adult ADHD and 66 with adult non-ADHD) were recruited in this study. All patients were subject to the following tests : Korean Wechsler Adult Intelligence Scale-IV (K-WAIS-IV), Executive Intelligence Test, Rey-Kim memory test, Beck’s Depression Inventory II (BDI-II), and Beck’s Anxiety Inventory (BAI), Adult ADHD Self-Report Scale (ASRS), Lee Ji-Yeon’s adult ADHD scale. @*Results@#:Compared to the adult non-ADHD group, the adult ADHD group showed lower score in Rey-Kim memory test. Several test scores were negatively correlated with ASRS (free recall test trial 2 : r=-0.184, p=0.047, trial 3 : r=-0.277, p=0.002, trial 4 : r=-0.242, p=0.009, trial 5 : r=-0.264, p=0.004, delayed recall test : r=-0.187, p=0.044, recognition test : r=-0.209, p=0.024). No significant correlation was found between depression, anxiety and Rey-Kim memory test even though there is a meaningful correlation between adult ADHD tendency the severity of depression and anxiety. @*Conclusion@#:In this study, we found the adult ADHD with depression group has difficulties in retaining information and maintaining attention. Interestingly, it was proved the difference comes from ADHD tendency, not from the severity of depression or anxiety.
Résumé
High-voltage electrical burn injuries on the scalp often result in scalp and cranial bone necrosis. Repetitive debridements and rich-vascularized flap coverage of the cranium are required. However, despite successful flap coverage, chronic osteomyelitis of cranial bones may occur. Treatment of chronic osteomyelitis of cranial bones is surgical debridement of the necrotic bone with re-coverage by a well-vascularized flap. The latissimus dorsi musculocutaneous flap is suitable not only for coverage of the cranium after the burn injury, but also for treatment of chronic osteomyelitis of the skull.

Objectives@#This study surveyed the quality of psychotherapy training and psychotherapy competencies during residency in Korea. @*Methods@#A questionnaire developed by The Committee of Residency Training of the Korean Neuropsychiatric Association was completed by fourth-year residents of Korean psychiatry (n=120). The questionnaire examined their demographic characteristics, their experience of clinical psychotherapy training, their degree of satisfaction in the quality of psychotherapy training, and self-rated competence regarding the six types of psychotherapies, including supportive psychotherapy, cognitive behavioral therapy, interpersonal psychotherapy, psychoanalytic psychotherapy, group psychotherapy, and family psychotherapy. @*Results@#The degree of satisfaction of the residents with the psychotherapy training was diverse among the types of psychotherapy and contents of training. Across all types of psychotherapies, the satisfaction levels of the quantity and quality of supervision education were low, except for psychoanalytic psychotherapy. Overall, more than 70% of residents were not satisfied with the theoretical education, clinical practice, and supervision education in three types of psychotherapies, including interpersonal psychotherapy, group psychotherapy, and family psychotherapy. A positive correlation was found between the degree of satisfaction with the quality of training experience and self-rated competence of psychotherapy. Specifically, the self-rated competence of psychotherapy was more highly correlated with the experience of clinical cases and supervision than theoretical education @*Conclusion@#This study showed the quantitative and qualitative status of psychotherapy training in Korean psychiatry residency programs, and the satisfaction level of psychotherapy education was low except for psychoanalytic psychotherapy. There is a strong need for the improvement of psychotherapy training programs in Korea.

Résumé
Purpose@#Because insertion of a foreign body (FB) into the anus is considered a taboo practice, patients with a retained rectal FB may hesitate to obtain medical care, and attending surgeons may lack experience with removing these FBs. We performed this study to evaluate the clinical characteristics of Korean patients with a retained rectal FB and propose management guideline for such cases based on our experience. @*Methods@#We retrospectively investigated 14 patients between January 2006 and December 2018. We assessed demographic features, mechanism of FB insertion, clinical course between diagnosis and management, and outcomes. @*Results@#All patients were male (mean age, 43 years) and presented with low abdominal pain (n = 2), anal bleeding (n = 2), or concern about a retained rectal FB without symptoms (n = 10). FB insertion was most commonly associated with sexual gratification or anal eroticism (n = 11, 78.6%). All patients underwent general anesthesia for anal sphincter relaxation with the exception of 2 who underwent FB removal in the emergency department. FBs were retrieved transanally using a clamp (n = 2), myoma screw (n = 1), clamp application following abdominal wall compression (n = 2), or laparotomy followed by rectosigmoid colon milking (n = 2). Colotomy and primary repair were performed in four patients, and Hartmann operation was performed in one patient with fecal peritonitis. No morbidity or mortality was reported. All patients refused postextraction anorectal functional and anatomical evaluation and psychological counseling. @*Conclusion@#Retained rectal FB is rare; however, colorectal surgeons should be aware of the various methods that can be used for FB retrieval and the therapeutic algorithm applicable in such cases.
Résumé
Background@#Patients with axillary osmidrosis suffer from a foul odor due to the bacterial decomposition of apocrine gland secretions. This condition is stressful, especially for teenaged students and young working people in Korea, who seek a reliable method for reducing odor that allows them to quickly return to school or work after surgery. Thus, surgeons must seek ways to effectively remove sweat glands with minimal complications. The conventional subdermal excision method has been widely used for the removal of sweat glands, but it can have many complications. The purpose of this study is to determine whether liposuction combined with diode laser ablation is effective for sweat gland removal compared with the subdermal excision method. @*Methods@#From 2011 to 2017, we compared two surgical methods for osmidrosis: subdermal excision and liposuction combined with diode laser ablation. An objective analysis of sweat (apocrine) gland count, determined by histopathological examinations of preoperative and postoperative punch biopsy specimens, was combined with a subjective assessment of patients’ symptoms (malodor grade) preoperatively and postoperatively. @*Results@#A larger percentage of sweat glands were removed by subdermal excision than by liposuction with diode laser ablation. However, no statistically significant difference was found between the two methods with regard to the percentage of apocrine glands removed. Liposuction with diode laser ablation had fewer perioperative complications and higher patient postoperative satisfaction than subdermal excision. @*Conclusions@#Liposuction with diode laser ablation is a useful method for axillary osmidrosis surgery in teenaged students and young working people in Korea.

We did immediate fasciotomy on forearm and late flap coverage with skin graft in this patient with good results.
Résumé
Objectives@#This study surveyed the quality of the residency training program and clinical competence of Korean psychiatry residents and psychiatrists. @*Methods@#Questionnaires regarding the quality of residency training and clinical competence were administered to Korean psychiatry residents (n=102) and psychiatrists (n=157). The authors analyzed the quality of training education according to the training environment and the correlation between the quality of training and the self-assessment competence level. @*Results@#The average score of the quality of training evaluated by the residents (n=102) was 3.57 (±1.00). Groups with more than or equal to three residents (annual) scored higher (3.69±1.03) than the groups with less than or equal to two residents (3.52±0.99). Groups with more than or equal to seven teaching psychiatrists scored higher (3.42±1.03) than the groups with less than or equal to six teaching psychiatrists (3.42±1.03). The quality of training and self-assessment competence showed a significant static correlation in the residents (R2=0.488, p<0.01) and psychiatrists (R2=0.508, p<0.01). @*Conclusion@#This study shows that the quality of residency education varies according to the clinical area and the environment. The importance of training education is emphasized by the static correlation between the quality of education and clinical competence.
Résumé
Objective@#The objective of the present study was to explore causal pathways to understand how second traumatic experiences could affect the development of emotional exhaustion and psychiatric problems. @*Methods@#A total of 582 workers who had jobs vulnerable to secondary traumatic experiences were enrolled for this study. Emotional exhaustion, secondary trauma, resilience, perceived stress, depression, anxiety, and sleep problems were evaluated. A model with pathways from secondary traumatic experience score to depression and anxiety was proposed. The participants were divided into three groups according to the resilience: the low, middle and high resilience group. @*Results@#Resilience was a meaningful moderator between secondary traumatic experiences and psychiatric problems. In the path model, the secondary trauma and perceived stress directly and indirectly predicted perceived stress, emotional exhaustion, depression, anxiety, and sleep problems in all three groups. Direct effects of perceived stress on depression and anxiety were the largest in the low resilience group. However, direct effects of secondary trauma on perceived stress and emotional exhaustion were the largest in the high resilience group. @*Conclusion@#Understanding the needs of focusing for distinct psychological factors offers a valuable direction for the development of intervention programs to prevent emotional exhaustion among workers with secondary traumatic experiences.
Résumé
Background@#Presenteeism has emerged as an important health-related issue and has been studied in a variety of occupation groups. This study examines the relationship between emotional labor and presenteeism in nurses in Republic of Korea. @*Methods@#As a cross-sectional study, our study was conducted on 328 female nurses participating in the fourth Korean Working Conditions Survey (2015). Nurses were identified by the Korean Industry Classification Code. Multivariable logistic regression analysis was performed to explore the association between emotional labor and presenteeism. @*Results@#Female nurses who always or sometimes hide their emotions in the workplace were found to have a high risk for presenteeism compared with female nurses who rarely hide their emotions in the workplace {odds ratio [OR] = 2.40 [95% confidence interval (CI) 1.04–5.54]; OR = 4.12 [95% CI 1.72–9.84], respectively}. Furthermore, the risk of presenteeism was higher in nurses who sometimes engaged with complaining customers compared with nurses who rarely did so, but it lacked statistical significance. @*Conclusion@#Presenteeism in nurses can cause various negative secondary effects; therefore, an alternative should be sought to mediate nurses' emotional labor to prevent presenteeism.
Résumé
PURPOSE: We evaluated the risk factors for posthepatectomy thrombosis including portal vein thrombosis (PVT) and clinical outcomes. METHODS: We retrospectively analyzed 563 patients who had undergone hepatectomy from February 2009 to December 2014. Twenty-nine patients with preoperatively confirmed thrombosis and tumor recurrence-related thrombosis were excluded. We identified the location of the thrombosis as main portal vein (MPV), peripheral portal vein (PPV) and other site such as hepatic vein or inferior vena cava. Patients with MPV thrombosis and PPV thrombosis with main portal flow disturbance were treated with anticoagulation therapy. We performed operative thrombectomy before anticoagulation therapy who did combined portal vein (PV) segmental resection. RESULTS: Of the 534 patients, 22 (4.1%) developed posthepatectomy thrombosis after hepatectomy. Among them, 19 (86.4%) had PVT. The mean duration of Pringle's maneuver was significant longer in the PVT group than the no-thrombosis group (P = 0.020). Patients who underwent combined PV segmental resection during hepatectomy were more likely to develop posthepatectomy PVT (P = 0.001). Thirteen patients who had MPV thrombosis and PPV thrombosis with main portal flow disturbance received anticoagulation therapy immediately after diagnosis and all of them were improved. Among them, 2 patients who developed PVT at the PV anastomosis site after PV segmental resection, underwent operative thrombectomy before anticoagulation therapy and both were improved. There were no patients who developed complications related to anticoagulation therapy. CONCLUSION: Long duration of Pringle's maneuver and PV segmental resection were risk factors. Anticoagulation therapy or operative thrombectomy should be considered for PVT without contraindications.

BACKGROUND: Headache/eyestrain symptoms are common health problems that people experience in daily life. Various studies have examined risk factors contributing to headache/eyestrains, and physicochemical exposure was found to be a leading risk factor in causing such symptoms. The purpose of this study was to examine the relationship of headache/eyestrain symptoms with physicochemical exposure among Korean construction workers depended on worksite.METHODS: This study used data from the 4th Korean Workers Conditions Survey and selected 1,945 Korean construction workers as participants. Multivariable logistic regression analysis was used to determine the relationship.RESULTS: Exposure to vibrations among all construction workers affected the moderate exposure group [odds ratio (OR) 1.53, 95% confidence interval (CI) 1.01–2.32], the high exposure group (OR 1.77 95%CI 1.17–2.67), and the indoor high exposure group (OR 1.61, 95%CI 1.02-2.55) and among outdoor construction workers, the moderate group (OR 6.61, 95%CI 15.4–28.48) and the high group (OR 6.61, 95%CI 1.56–27.98). When exposed to mist, dust, and fumes, the indoor high exposure group was significantly affected (OR 1.63, 95%CI 1.07–2.47). All construction workers exposed to organic solvents were affected, high exposure group (OR 1.69, 95%CI 1.15–2.49) and indoor high exposure group (OR 1.77, 95%CI 1.08–2.89). The high exposure group in all construction worker (OR 1.70, 95%CI 1.20–2.42) and the indoor high exposure group (OR 1.83, 95%CI 1.17–2.89) also were affected by secondhand smoking exposure.CONCLUSION: Many physicochemical exposure factors affect headache/eyestrain symptoms among construction workers, especially indoor construction workers, suggesting a deficiency in occupational hygiene and health environments at indoor construction worksites.
