Background: This study aimed to identify the clinical characteristics of multidrug-resistant/ rifampicin-resistant tuberculosis (MDR/RR-TB) in the Republic of Korea. Methods: Data of notified people with tuberculosis between July 2018 and December 2021 were retrieved from the Korea Tuberculosis Cohort database. MDR/RR-TB was further categorized according to isoniazid susceptibility as follows: multidrug-resistant tuberculosis (MDR-TB), rifampicin-monoresistant tuberculosis (RMR-TB), and RR-TB if susceptibility to isoniazid was unknown. Multivariable logistic regression analysis was conducted to identify the factors associated with MDR/RR-TB. Results: Between 2018 and 2021, the proportion of MDR/RR-TB cases among all TB cases and TB cases with known drug susceptibility test results was 2.1% (502/24,447). The proportions of MDR/RR-TB and MDR-TB cases among TB cases with known drug susceptibility test results were 3.3% (502/15,071) and 1.9% (292/15,071), respectively. Among all cases of rifampicin resistance, 31.7% (159/502) were RMR-TB and 10.2% (51/502) were RR-TB. Multivariable logistic regression analyses revealed that younger age, foreigners, and prior tuberculosis history were significantly associated with MDR/ RR-TB. Conclusion Rapid identification of rifampicin resistance targeting the high-risk populations, such as younger generations, foreign-born individuals, and previously treated patients are necessary for patient-centered care.

OBJECTIVES: This study compares single and repeat suicide attempts, and evaluates the risk factors associated with suicide re-attempts. METHODS: Two hundred and seventy-nine patients admitted to emergency rooms in four university hospitals in Daegu after suicide attempt were included in this study (n=179 single suicide attempters, n=100 repeated attempters). A structured interview focused on demographic, clinical, suicidal and psychological characteristics was administered to these patients after recovery from physical and psychological impairments. RESULTS: Individuals with repeated suicide attempts were younger, more highly educated, had more history of psychiatric treatments, took more psychiatric medications, and had more sustained suicidal ideations, bipolar disorders and personality disorders than individuals with single suicide attempt. Individuals with repeated suicide attempts marked significantly higher scores in the Childhood Trauma Questionnaire, Patient Health Questionnaire-9, and the Barratt Impulsiveness Scale. Multivariate logistic regression showed that below the sixties, history of psychiatric treatments, personality disorders, substance use disorders and sustained suicidal ideations were significantly associated with predictive factors for subsequent suicide attempt. CONCLUSION: Our findings suggest that repeat suicide attempters have different clinical characteristics from single suicide attempters, and some risk factors raise the risk of further suicide attempts. It is necessary for suicidal prevention program planners to be aware of these risk factors, especially for first-time suicide attempters.

OBJECTIVE: Schizophrenia and bipolar disorder are characterized by the presence of neurocognitive impairments on the psychosis continuum. The present study aimed to explore the shared and distinct endophenotypes between these disorders. METHODS: The study included 34 probands with remitted schizophrenia and 34 probands with euthymic bipolar disorder who had a history of psychotic symptoms that met the Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV) criteria, unaffected first-degree relatives of probands (31 relatives of probands with schizophrenia and 29 relatives of probands with bipolar disorder), and 34 healthy controls. Cognitive assessments were performed using the digit span, continuous performance, Rey auditory and visual learning, complex figure, verbal fluency, Wisconsin card sorting, and finger tapping tests. RESULTS: Probands with schizophrenia showed the most generalized and severe cognitive deficits across cognitive domains (working memory, verbal learning and memory, visual memory, verbal fluency, and executive function). Some domains of cognitive function (working memory, verbal learning, and memory) were also impaired in probands with bipolar disorder, but to a lesser degree than in probands with schizophrenia. All probands and relatives showed a common deficit in working memory compared to healthy controls. Relatives of probands with schizophrenia also showed verbal fluency dysfunction. Cognitive performance of all relatives was intermediate to the performance of both patients and healthy controls. CONCLUSION: These findings suggest that a deficit in working memory could be a shared endophenotype of genetic vulnerability to schizophrenia and psychotic bipolar disorder, and verbal fluency could be a candidate endophenotype for schizophrenia specifically.

PURPOSE: The authors retrospectively compared single-port laparoscopic appendectomy (SPLA) with conventional laparoscopic appendectomy (CLA) in terms of the perioperative outcomes in pediatric patients. METHODS: Cases of laparoscopic appendectomy between December 2009 and July 2010 were retrospectively reviewed. The demographic data, operating time, pathology of the appendix, hospital stay and surgical morbidities were compared. RESULTS: Ten patients underwent SPLA and 57 underwent CLA. The mean age of the CLA and SPLA groups were 11.2 and 10.6 years, respectively. The pathology of the appendix showed that relatively more severe cases were included in the CLA group. There were 2 cases of a post operative intra-abdominal abscess and 2 cases of an umbilical wound infection in the SPLA group. Therefore, the SPLA group showed a significantly higher surgical morbidity rate (p=0.003) and hospital stay (p=0.05). The mean operation time of the SPLA and CLA group was 88.1+/-30.1 and 71.6+/-26.3 minutes, respectively; the mean operation time of the SPLA group was slightly longer (p=0.054). On the other hand, surgical morbidity and the mean operation time showed a decreasing tendency in the latter half of 10 cases. CONCLUSION: The initial experience of SPLA in pediatric patients shows a higher complication rate and longer hospital stay than CLA. On the other hand, the complication rates and operation time have been decreasing. The clinical outcomes are expected to improve after going through a learning curve.

Currarino syndrome is a hereditary syndrome characterized by the triad of a sacral bony defect, presacral mass and anorectal malformation. We retrospectively reviewed 13 Currarino syndrome patients who were treated in our center between 1997 and 2010. Demographic data, initial symptoms, initial diagnosis, pathologic diagnosis of presacral mass, associated anomalies and managements were analyzed. There were 8 boys and 5 girls. Four patients were diagnosed as Currarino syndrome immediately after birth with failure of passage of meconium and abdominal distension. Four patients underwent surgery for imperforate anus immediately after birth and were diagnosed as Currarino syndrome later and underwent reoperation. Three patients were diagnosed during work-up and management with of the tentative diagnosis of Hirschsprung's disease. Diagnosis of the remaining two patients was at the age of 26 months and 9 years and anorectal malformation was not associated. Twelve patients showed hemi-sacrum and one patient showed bilateral sacral subtotal agenesis. Two patients without anorectal malformation underwent presacral mass excision, untethering of spinal cord and repair of myelomeningocele. Six out of 8 patients, excluding 3 that expired or were lost to follow up, with anorectal malformation underwent colostomy, presacral mass excision, untethering of spinal cord, repair of myelomeningocele, posterior sagittal anorectoplasty and colostomy repair. One patient underwent only posterior sagittal anorectoplasty after colostomy. One waits the scheduled operation only with Hegar dilatation. Pathologic examation of presacral masses showed myelomeningoceles in 4 patients, lipomyelomeningoceles in 3 patients and dermoid cyst in one patient. Teratoma was combined in 2 patients. Eight patients needed neurosurgical operation for spinal cord problems. Seven patients had urologic anomalies and two of them underwent operation. Currarino syndrome should be considered as a differential diagnosis in pediatric patients with abdominal distension, constipation and anorectal malformation. For proper evaluation and treatment, a multi-disciplinary approach is recommended.

Extracorporeal membrane oxygenation (ECMO) has been utilized in congenital diaphragmatic hernia (CDH) patients with severe respiratory failure unresponsive to conventional medical treatment. We retrospectively reviewed 12 CDH patients who were treated using ECMO in our center between April 2008 and February 2011. The pre ECMO and on ECMO variables analyzed included gestational age, sex, birth weight, age at the time of ECMO cannulation, arterial blood gas analysis results, CDH location, timing of CDH repair operation, complications and survival. There were 9 boys and 3 girls. All patients were prenatally diagnosed. Mean gestational age was 38.8 +/- 1.7 weeks and mean birth weight was 3031 +/- 499 gram. Mean age at the time of ECMO cannulation was 29.9 +/- 28.9 hours. There were 4 patients who survived. Survivors showed higher 5 min Apgar scores (8.25 +/- 0.96 vs. 7.00 +/- 1.20, p=0.109), higher pre ECMO mean pH (7.258 +/- 0.830 vs. 7.159 +/- 0.986, p=0.073) and lower pre ECMO PaCO2 (48.2 +/- 7.9 vs. 64.8 +/- 16.1, p=0.109) without statistical significance. The hernia was located on the left side in 10 patients and the right side in 2 patients. The time interval from ECMO placement to operative repair was about 3~4 days in 5 early cases and around 24 in the remaining cases. There were 3 cases of post operative bleeding requiring re operation and 2 cases of abdominal compartment syndrome requiring abdominal fascia reopening. ECMO catheter reposition was required in 4 cases. Three cases of arterial or venous thrombosis were detected and improved with follow up. Our data suggests that ECMO therapy could save the lives of some neonates with CDH who can not be maintained on other treatment modalities. Protocolized management and accumulation of case experience might be valuable in improving outcomes for neonates with CDH treated with ECMO.
