RESUMEN
Objective@#The economic hardship brought by the coronavirus disease-2019 (COVID-2019) pandemic has caused mental health problems among people of different socioeconomic status (SES). As social support helps to buffer these problems, we investigated the association between job loss related to COVID-19 and depression, anxiety, and suicidal thoughts; the differences in the effects according to SES; and the mediating effects of social support. @*Methods@#The effects of COVID-19-related job loss on depression, anxiety, and suicidal thoughts among 1,364 people were investigated through semi-structured and self-administered questionnaires: Patient Health Questionnaire–9, General Anxiety Disorder–7, and the Functional Social Support Questionnaire. Logistic regression and subgroup analyses were performed to assess the association between job loss and mental health status, and the moderating effects of income and educational levels. Moreover, the mediating effects of perceived social support on the association between job loss and depression, anxiety, and suicidal thoughts were analyzed. @*Results@#COVID-19-related job loss increased the risk of depression and suicidal thoughts. Adults with lower income and education level were at higher risk of depression, anxiety, and suicidal thoughts; perceived social support level had significant mediating effects on the association between job loss and depression/anxiety; and income level had significant moderating effects on this mediating pathway. @*Conclusion@#COVID-19-related job loss were likely to be significantly associated with negative mental health outcomes, especially among individuals with low income and education levels. As social support had buffering effects on such outcomes, related government policies in cooperation with the governance of communities and stakeholders must be prepared.
RESUMEN
Objective@#This study aimed to observe the changes in people’s depressive levels over 9 months since the coronavirus disease of 2019 (COVID-19) outbreak as well as to identify the predictors of people’s depressive levels including COVID-19 infection fear in the context of South Korea in 2020. @*Methods@#For these purposes, four cross-sectional surveys were periodically implemented from March to December 2020. We randomly recruited 6,142 Korean adults (aged 19 to 70) by using a quota survey. Along with descriptive analysis, which included a one-way analysis of variance and correlations, multiple regression models were built to identify the predictors of people’s depressive levels during the pandemic. Results Overall, people’s depressive levels and fear of COVID-19 infection gradually increased since the COVID-19 outbreak. In addition to demographic variables (i.e., being a female, young age, unemployed, and living alone) and the duration of the pandemic, people’s COVID-19 infection fear was associated with their depressive levels. @*Conclusion@#To ameliorate these rising mental health issues, access to mental health services should be secured and expanded, particularly for individuals who present greater vulnerabilities due to socioeconomic characteristics that may affect their mental health.
RESUMEN
Background@#The coronavirus disease 2019 (COVID-19) outbreak and subsequent disease-containment measures (such as school closures) significantly affected the lives of adolescents. We evaluated the mental-health status and factors associated with anxiety and depression among South Korean adolescents. @*Methods@#A nationwide online survey was conducted to evaluate the mental-health status of South Korean adolescents during the COVID-19 pandemic. In total, 570 adolescents aged 13–18 years were surveyed between May 27 and June 11, 2021. The participants completed the Generalized Anxiety Disorder Scale (GAD-7) and Patient Health Questionnaire (PHQ-9) to determine anxiety and depression symptoms, respectively. Stepwise logistic regression models were constructed to determine factors related to anxiety and depression. @*Results@#Among the study participants, 11.2% and 14.2% had anxiety and depression, respectively. The results suggested that several factors, such as the experience of COVID-19 infection and quarantine of oneself, a family member or an acquaintance, physical and mental health problems, and fear of one’s local community being discriminated against as a COVID-19 area were related to anxiety and depression. @*Conclusion@#The present study identified COVID-19-related factors associated with anxiety and depression among adolescents, and provides insights regarding potential interventions to improve the mental health of adolescents. To promote the mental health of adolescents during the COVID-19 pandemic, special attention should be paid to individuals with physical or mental-health problems, and efforts should be made to reduce the negative social and emotional impacts of infection-control measures.
RESUMEN
As of April 18, 2020, there have been a total of 10,653 confirmed cases and 232 deaths due to coronavirus disease 2019 (COVID-19) in Korea. The pathogen spread quickly, and the outbreak caused nationwide anxiety and shock. This study presented the anecdotal records that provided a detailed process of the multidisciplinary teamwork in mental health during the COVID-19 outbreak in the country. Psychosocial support is no less important than infection control during an epidemic, and collaboration and networking are at the core of disaster management. Thus, a multidisciplinary team of mental health professionals was immediately established and has collaborated effectively with its internal and external stakeholders for psychosocial support during the COVID-19 outbreak.
RESUMEN
PURPOSE: Failure of hematopoietic stem cell transplantation(HSCT) may be encountered in practice because of either relapse of the malignancy or dysfunction of the graft. Second HSCT may be the only option for some patients whose initial HSCT failed. METHODS: From May, 1991 to December, 2004, 115 HSCTs were performed at the Pediatric Blood & Marrow Transplantation Center, Chonnam National University. This study was a retrospective analysis of the medical records of 15 patients who received the second HSCT after initial graft. RESULTS: Among eight patients with nonmalignant diseases, two patients underwent the second HSCT because of primary graft failure and five because of late graft rejection. The remaining Fanconi anemia patient was re-transplanted due to development of AML. Two patients died and one experienced primary graft failure, but is still alive. The Kaplan-Meier 5-year overall survival rate was 75 percent and the disease free survival rate was 62.5 percent in nonmalignant diseases. All malignant patients underwent second transplants because of relapses. Four died of relapse and one of treatment-related complications. The Kaplan-Meier 2-year overall and event free survival rate was 28.6 percent each in malignant diseases. CONCLUSION: Second HSCT for graft dysfunction of nonmalignant disease seems to be feasible and should be considered as a standard practice. The relapse of malignant diseases remains a big obstacle even after the second HSCT, although a small portion of patients might be salvaged. Further investigation of novel therapeutic strategies, as well an the understanding of the biology should be explored.

PURPOSE: In order to monitor the clinical outcome of pediatric allogeneic stem cell transplantation (SCT), serial evaluations of chimerism were performed to compare the risk of relapse or graft rejection between patients with complete chimerism (CC) and mixed chimerism (MC). METHODS: Between January, 1996 and April, 2004, 64 cases who underwent SCTs were prospectively enrolled. Serial genotyping of VNTR (variable number of tandem repeats) /STR (short tandem repeats) loci and/or X-chromosome-specific FISH (fluorescent in situ hybridization) were performed at regular intervals. RESULTS: The "informative loci" were found in all 64 patient/donor pairs. CC was persistently detected in 44 cases (68.7%), while MC was detected at least once in 20 (31.3%). In cases with malignancy (n=40), relapse was more frequently encountered in MC group (7/8) than in CC group (7/32) (P < .001), as was death (75% vs. 28%, P < .05). The Kaplan-Meier 5-year overall survival was higher in CC than in MC (69.1% vs. 16.6%; P < .05). In cases with non-malignancy, MC group showed higher rate of graft rejection than CC group (7/12 vs. 1/12, P < .01). Survival was not different between the two groups. The chimerism status was not influenced by sex, donor type, source of stem cells, and inclusion of radiation in conditioning. CONCLUSION: Detection and sequential assessment of MC might be an important tool to predict relapse of disease in malignant diseases as well as to portend graft rejection in non-malignant illnesses. Earlier intervention to circumvent those life-threatening complications should be pursued based on the chimerism analyses.

PURPOSE: Pericentric inv (9) occurs in about 0.8~2% of the normal population. The implication of inv (9) in hematological malignancies and/or in stem cell transplantation (SCT) has not been thoroughly elucidated. METHODS: To further delineate the characteristics, we describe our experiences of inv (9) in 2 patients who underwent SCTs and 1 patient with ALL. RESULTS: Case 1. An 11-year-old girl with AML M2 showed 46, XX, inv (9). After remission, her consolidation cycles were associated with slow platelet recovery. She underwent autologous BMT, however, the engraftment was rather slow, and relapsed at 7 months. 2nd remission was achieved after prolonged cytopenia. She underwent reduced intensity unrelated cord blood transplant. Her posttransplant course was uneventful with ANC & gt; 500/microL at D+18 and platelet > 50 k/microL at D+38. Karyotyping showed 46, XY. She is now well at 16 months after 2nd transplant. Case 2. A 10-year-old girl presented with severe aplastic anemia. Karyotyping was normal. She underwent matched sibling transplantation. Her post-transplant course was uneventful with rapid engraftment. Cytogenetics showed 46, XX, inv (9), which was originated from her sister. She is now well at 70 months posttransplant. Case 3. A 3-year-old boy with ALL had a karyotype of 46, XY, inv (9) (p11q12). His clinical course was uneventful. CONCLUSION: The first case showed typical course of delayed recovery after chemotherapy and delayed engraftment after autologous transplantation. inv (9) should be considered in cases of otherwise unexplainable delay in recovery after chemotherapy or delayed engraftment after SCT. Further studies involving larger number of cases should be warranted to delineate the exact role of inv (9) in pediatric leukemia and SCTs.

BACKGROUND: Postremission therapy is critical for achieving long-term survival in the patients with acute myelogenous leukemia (AML). Allogeneic bone marrow transplantation during the first complete remission (CR) with using a HLA-identical sibling donor may offer the best chance for long-term leukemia-free survival. The patients without matched siblings have several treatment options. The aim of this study was to compare the clinical outcomes after matched sibling transplantation (MST), unrelated stem cell transplantation (non-MST), or autologous peripheral blood stem cell transplantation (APBSCT) as a postremission therapy for children with AML. METHODS: Thirty four hematopoietic stem cell transplantations (SCT) in 32 children with AML were performed between June, 1996 and December, 2004. Two patients who failed at prior APBSCT underwent a 2nd unrelated transplantations. The disease status at the time of transplantation, the conditioning regimen, prophylaxis for graft-versus-host disease (GVHD), the incidence of GVHD, complications, the cause of death, the over-all survival and the event-free survival were retrospectively compared in relation to the stem cell sources. RESULTS: There were 19 males and 13 females with a median age of 8 yr 10 mo. The median follow-up was 17 mo. Twenty-eight cases were transplanted during CR1. Most (5/6) of patients other than the patients who were in CR1 were allocated in the non-MST group. APBSCT was done in 17 cases, and allo-transplants were done in 17 cases, which included MSTs in 10, matched-unrelated BM transplants in 5, haploidentical CD34+selected peripheral blood transplant in 1, and 1-antigen mismatch unrelated cord blood transplantation in 1. Acute GvHD > or = than Grade 2 was found in 20% of the MST cases vs. 85.7% in the non-MST cases (P<.01). The two-year cumulative relapse risks were 46.4% in the APBSCT cases, 20% in the MST cases and 31.5% in the non-MST cases. The Kaplan-Meier 2-year EFS in all cases was 55.7%: 46.3% in the APBMT cases, 80.0% in the MST cases and 68.6% in the non-MST cases, despite the higher proportion of high risk patients in the non-MST group. CONCLUSION: This study indicated that MST was the best option for pediatric AML. For patients without matched siblings, the patients with unrelated transplants fared better, had better survival and a lower relapse rate than the APBSCT patients. However, a further prospective, randomized study that incorporates a larger number of patients and a cord blood transplant arm is necessary to definitely determine the best option for pediatric AML.

Isolated relapse of myeloid leukemia as a granulocytic sarcoma(GS) following allogeneic bone marrow transplantation(BMT) is very rare manifestation, and usually associated with a poor prognosis. We report a case of isolated intracranial GS in an infant with myelodysplastic syndrome(MDS) following unrelated BMT. A 7 month-old girl was diagnosed with refractory anemia with excess blasts (RAEB). During observation for a couple months several GS developed in the scalp and blast counts in BM increased. Induction chemotherapy resulted in partial remission of BM but GS disappeared. Four months after diagnosis, an unrelated BMT was undertaken. Engraftment was uneventful. On D+160, an intracranial GS of 6.5 cm in size developed. A craniotomy and tumor removal was done. There was no evidence of relapse in BM with complete chimerism. Reinduction chemotherapy using IDA-FLAG resulted in profound neutropenia with pneumonia. She succumbed to respiratory failure despite leukocyte recovery. The optimal management for isolated relapse as GS following BMT should be established.

PURPOSE: Granulocytic sarcoma (GS), an extramedullary tumor consisting of primitive myeloid cells, is a rare manifestation of acute myelogenous leukemia (AML). However, GS can occasionally precede the development of systemic leukemia by weeks to years. The objectives of this study are to describe the frequency, clinical characteristics and survival of AML children with GS from a single Korean institute. METHODS: Retrospective review of all the AML children who presented between January, 1995 and June, 2003 was undertaken. RESULTS: GS developed in 9 children among 118 AML patients (incidence, 7.6%). The median age at diagnosis of AML was 82 months (8 months~13 years) with equal sexual distribution. The sites of GS were scalp (n=4), skull (n=3), paranasal sinuses (n=1), external auditory canal (n=1), spinal epidura (n=1), and spinal intramedulla (n=1). The symptoms related with GS were scalp mass (n=4), paraparesis (n=3), facial nerve palsy (n=3), hearing impairment (n=2), and exophthalmos (n=1). In the case with spinal epidural mass, GS preceded the diagnosis of AML by 15 months. Cytogenetics were available in 8 cases, and t (8; 21) was found in five cases. All cases received systemic chemotherapy, with surgical decompression and radiotherapy for 2 patients involving spine. Seven cases received stem cell transplantations (3, allogeneic bone marrow; 4, autologous peripheral blood). The 5-yr event-free survival was 35.0% by Kaplan-Meier method. All 3 allografted patients are alive (86 mo, 5 mo, 1 mo), while 3 of 4 autografted patients had either died or relapsed. CONCLUSION: GS should be considered in patients with or even without AML who have palpable mass or neurological manifestation. Effective treatment, including allogeneic stem cell transplantation, should be considered to achieve a durable disease control.

PURPOSE: We analyzed a cohort of patients with Langerhans cell histiocytosis (LCH) to understand the clinical findings, optimal management, and outcome of the disease. METHODS: We performed a retrospective clinical study of LCH from January 1993 to August 2002 at Chonnam National University Hospital. All 39 patients with histologically proven histiocytosis were categorized into Class I (n=22), Class II (n=15) and Class III (n=2) by WHO classification. RESULTS: There were 18 males and 21 females. Mean age at diagnosis was 3.2 years. The common clinical manifestations of Class I were soft tissue swelling, skin rash or nodule, otorrhea; and those of Class II were hepatosplenomegaly, fever, and respiratory symptoms. The most commonly involved organ of Class I was the skeleton; and that of Class II was bone marrow. Abnormal hematologic findings were found in 23 patients, especially in all Class II patients. Infectious etiology was documented in 5 Class II patients (CMV in 3, EBV in 1, mycoplasma in 1). Chemotherapy was given to 19 out of 22 Class I patients. Six of them showed complete remission. Four died during chemotherapy. The overall survival of Class I patients was 78% and that of Class II 63%. Poor prognostic factors of Class I were age 1.5 mg/dL. CONCLUSION: The Langerhans cell histiocytosis is a heterogeneous disorder of significant morbidity and mortality. Early recognition and aggressive medical treatment might improve the survival rate.

Selective IgA deficiency is one of the most common primary immunodeficiency. Some patients with IgA deficiency also have deficits in one or more immunoglobulin G subclasses. It has been estimated that up to 25% of patients with certain primary immunodeficiencies will develop tumors, primarily B-cell lymphomas during their lifetime. We hereby present 2 cases of malignant lymphomas, one diffuse large cell lymphoma and another mixed cellularity Hodgkin's disease, respectively, which developed in patients with selective IgA and IgG subclass deficiency.

PURPOSE: Hepatic veno-occlusive disease (VOD) is a life-threatening complication occurring early after stem cell transplantation (SCT). Early diagnosis and effective treatment has not been established in severe VOD. Because there are few reports on VOD in Korean children, we evaluated the clinical characteristics of VOD following SCT in children. METHODS: We retrospectively reviewed the chart of all patients (n=116) receiving SCTs in CNUH Pediatric BMT center between May, 1991 and June, 2004. RESULTS: VOD developed in 11 patients (9.5%) (median age, 9.8 years; range, 2 to 13.9). Underlying diagnoses were ALL (n=3), severe aplastic anemia (n=3), AML (n=2), acute biphenotypic leukemia (n=1), neuroblastoma (n=1), and myelodysplastic syndrome (n=1). The median day of onset of VOD was D+9 (range, D-3 to D+19). VOD was classified as moderate in 5 and severe in 6 cases. Maximum level of serum total bilirubin was 2.9 mg/dL (range, 2.1 to 9.2) in moderate VOD and 7.3 mg/dL in severe VOD (range, 2.0 to 24.2) at D+18 (range, D-5 to D+59). We successfully treated VOD with various combinations including tPA and heparin (2/5, 40%), ursodeoxycholic acid (2/5, 40%), N-acetylcysteine (3/5, 60%), and defibrotide (1/2, 50%). All of 5 patients with moderate VOD survived at D+100 (range, 5.5+ to 66.6+ months). Five of 6 (83%) patients with severe VOD died within first 19 day from complications of VOD. CONCLUSION: This retrospective study showed that the incidence of VOD was 9.5%, and the mortality of severe VOD was still high which would necessitate early diagnosis, effective prevention and treatment.

PURPOSE: Langerhans cell histiocytosis (LCH) is a disorder characterized by the proliferation of activated Langerhans cells. Although current therapies are very effective at inducing remission, multiple recurrences and long-term sequelae are common for young patients. For this reason, more effective therapies based on the pathogenesis of LCH are needed. We investigated the use of 2-chlorodeoxyadenosine (2-CdA), a purine analogue with an antiproliferative effect on histiocytes and lymphocytes, in patients with recurrent or refractory LCH. METHODS: Four children with recurrent or refractory LCH received 2-CdA (5~7 mg/m2/day for 5 days, given as a 24-hr continuous infusion and repeated every 21~28 days for 5~7 courses). RESULTS: All four patients had multiorgan involvement, and were heavily pretreated. Of the two children with recurrent diseases, one had complete response and the other showed no active disease except for the remaining diabetes insipidus. Two infants who showed poor early response to previous combination chemotherapy also responded poorly: partial response in one, and progressive disease resulting in death in the other. Toxicity consisted mainly of myelosuppression, but significant infections did not occur. The peripheral neuropathy was not seen. CONCLUSION: 2-CdA, tolerable in children without significant side effects, might be effective for the treatment of recurrent LCH in children. However, the efficacy in infants with multi-system, refractory diseases needs further study. The feasibility of 2-CdA treatment as the first-line therapy for high-risk diseases, and the possibility of combination with other agents needs to be addressed in the future.

PURPOSE: Paroxysmal nocturnal hemoglobinuria (PNH) has been known to be a late clonal complication of aplastic anemia (AA). Flow cytometric analysis using CD55 and CD59 antibodies became the gold standard of diagnosing PNH, replacing a traditional, less sensitive Ham's test, as the pathophysiologic mechanism was identified as the deficiency of glycophosphatidyl-inositol anchored protein. Although the incidence of AA seems to be higher in Korea than that of other Western countries, the study of PNH in Korean pediatric AA has never been accomplished. We studied the frequency of PNH in AA, and tried to compare the characteristics of them with those from other countries. METHODS: Twenty-two pediatric AA patients were enrolled for the study. As a control, 5 patients with inherited bone marrow failure syndromes (Fanconi anemia, 1; Diamond-Blackfan anemia, 3; dyskeratosis congenita, 1) and 11 normal children were pooled. For the flow cytometry, 10muL each of CD55-PE and CD59-FITC was mixed with 50muL of whole blood and incubated for 15 min. Red cells were lysed with Q-prep apparatus (Coulter, Fullerton, USA). Beckman Coulter XL flow cytometer was used for the analyses. RESULTS: The median age for the patients was 14 years (range, 2~21). CD55- and CD59-negative cells from controls were 0.13+/-0.18%. Cut-off value for the diagnosis for PNH was designated as > 0.49%, which was mean +2 S.D. of controls. All the patients showed CD55- and CD59-negative PNH cell proportions within the normal ranges, except for a 19-year-old boy who was still cyclosporine-dependent after initial response to immunosuppressive therapy 4 years before. He had 4.79% of CD55- and CD59-negative PNH population. CONCLUSION: The frequency of PNH clones in Korean children with AA was low (1/22=4.5%). This might reflect the relatively low association of PNH in childhood AA, the limitation caused by small numbers of the study population, or true ethnic differences. A further study incorporating more patients seems to be warranted.

OBJECTIVE: To confirm practical usefulness of the newly invented automatic identifying instrument for the spinal epidural space. METHOD: Epidural block with blind approach has been done for the patients who suffered from lower back pain with radiating pain due to spinal disorders. Conventional blind approaches using the glass syringe (control group) and the newly invented instrument (experimental group) were applied to each 30 patients, respectively. Epidurography was used for the confirmation to conclude success or not. RESULTS: Two cases were failed in the control group. One case showed injected contrast media in the interspinal ligament, another case revealed dura-puncture. But there was no failure in the experimental group. The mean timefrom skin-penetration to epidurography was 299.7+/-13.6 second in control group and 184.0+/-16.3 second in experimental group. The mean time from changing to glass syringe (control group) or epidural detector (experimental group) to epidurography was 146.0+/-14.0 second in control group and 60.0+/-7.0 second in experimental group. The time for epidural block was much less in experimental group (p<0.001). CONCLUSION: This newly invented epidural detector could make the epidural block easier, safer, and faster. We suggest this instrument is useful complementary method for spinal epidural procedure.

The atlantoaxial joint has a little stability and is secured and supported chiefly by soft tissue such as ligaments and articular capsule, so it has free motions to all directions. Relaxation or rupture of these supportive structures due to inflammation or trauma may cause instability or subluxation, and it results in compression of the spinal cord and it reveals various neurologic symptoms. The atlantoaxial rotatory subluxation, the rare disease found in children mostly, is known to be one of the reasons of the temporal torticollis in children. An adult type is very rare, but it is possible to be combined with rheumatoid arthritis and/or trauma, but we experienced the 25-year-old female patient who had the atlantoaxial rotatory subluxation spontaneously without rheumatoid arthritis and/or trauma, so we report this case with review of literature.

BACKGROUND: Hemophiliacs are known to have higher risk of exposure of hepatitis virus and immunosuppression. The aim of this study is to investigate the positive rate of viral markers for hepatitis and anti-HIV and the changes of lymphocyte subpopulations in Hemophiliacs in Chonnam GwangJu area. METHODS: One hundred four patients who had visited to the Hemophilic Clinic, Chonnam University Hospital from 1999 to 2001 were enrolled. They were checked for type A, B, C hepatitis viral markers, anti-HIV and lymphocyte subpopulations. The prevalence of hepatitis and lymphocyte subpopulation were compared according to severity and age of hemophiliacs. RESULTS: Anti-HAV IgM, anti-HAV IgG, HBsAg, anti-HBs, anti-HCV were positive in 40%(22/55), 65.5%(66/101), 42.3%(42/97) of cases tested. Positivity of anti-HCV showed trends of increase according to the severity of hemophiliacs (P11 years old) (P=0.003, P<0.001, respectively). Although all enrolled patients were negative for anti-HIV, absolute T and B cells counts were decreased in 71.6% and 14.9% of patients, respectively and inversion of CD4/CD8 ratio were found in 65.7%. But there were no statistical difference in not only decrease of T and B cells but also inversions of CD4/CD8 ratio according to age and severity. CONCLUSION: The number of hemophiliacs with previous history of hepatitis B virus infection and seropositivity of anti-HCV were increased according to the age and severity of hemophilia. Active vaccinations of hepatitis B may be required in hemophiliacs. The greater part of hemophiliacs showed decrease in T cell count and inverted CD4/CD8 ratio. The hemophiliacs need a cautiion for infection and follow up tests for immunologic function.

We report a case of hepatocellular carcinoma presented with severe hypoglycemia. Computerized tomography and ultrasonography revealed a massive bilateral tumor with portal vein thrombosis. The levels of IGF-I (113 ng/mL) and IGFBP- (815 ng/mL) measured in the plasma, were lower than normal range. There was strong immunoreactivity of IGF- and IGF-I in immunohistochemical stain of tumor cells.
