Purpose: This study aimed to determine the level of health-related quality of life (HRQoL) of children and adolescents who received hematopoietic stem cell transplantation (HSCT) and to examine factors influencing HRQoL. Methods: This cross-sectional descriptive study involved 85 participants aged 10 to 19 years who received treatment from 3 months to 5 years after HSCT. Symptom experiences, stress and coping, self-esteem, social support, and HRQoL were measured. Descriptive analysis, the independent t-test, one-way analysis of variance, Pearson correlation analysis, and stepwise multiple regression were used for data analysis. Results: The mean HRQoL score was 72.26 points out of 100. HRQoL showed statistically significant correlations with symptom experiences, stress, self-esteem, social support, satisfaction with peer relationships, and perceived attentiveness of the medical team. The most influential predictors of HRQoL were symptom experiences (β=-.51, p<.001) and satisfaction with peer relationships (β=.32, p<.001). Conclusion The experiences of different symptoms by children and adolescents who receive HSCT must be considered. In addition, nursing interventions, such as self-help meetings with peer groups, should be provided to improve their HRQoL.

OBJECTIVE: This study was to change of pulp blood flow among maxillary and mandibular anterior tooth with mild crowding and adjacent teeth using Ultrasound Doppler graphy. METHODS: The change of pulp blood flow was measured three times using Ultrasound Doppler graphy; before the attachment of brackets, after 3 week, and after 6 week. The sample consists of 15 year old eighteen patients. RESULTS: Before the attachment of brackets, after 3 weeks, and after 6 weeks, there were no significant differences in the change of pulp blood flow in each part (maxilla and mandible) and each tooth according to period. In addition, to compare internal dangerousness of loss of the pulp vitality, when pulp blood flow is compared in each tooth before orthodontic treatment, there were no statistically significant differences in maxillary lateral incisor and mandibular canine but it showed low values in all measurement items (p > 0.05). CONCLUSIONS: Results of this study can be not only methodological preliminary data in further study such as tooth movement type of Ultrasound Doppler graphy and particular study considered the patient age, but also reference materials for the loss of pulp vitality in orthodontic treatment.

OBJECTIVES: To evaluate sleep characteristics and factors associated with sleep disturbance in schizophrenia patients with concurrent active psychotic symptoms and insomnia. METHODS: Schizophrenia patients with insomnia and active psychotic symptoms (n = 63) were recruited from communitybased mental rehabilitative facilities. Sleep scales such as the Korean version of the Insomnia Severity Index (ISI-K) and the Korean Version of the Pittsburgh Sleep Quality Index (PSQI-K) were evaluated and those with ISI-K >15 were included in the study. Psychotic, anxiety and depressive symptoms were rated with the Brief Psychotic Rating Scale (BPRS), the Korean Version of the Anxiety Sensitivity Index (K-ASI), and the Korean Version of the Beck Depression Inventory-I (K-BDI), respectively. Pearson correlation analyses were performed between the sociodemographic data, ISI-K and PSQI-K. Multiple linear regression analysis was conducted to investigate the factors which affected the ISI-K and PSQI-K. RESULTS: The mean ISI-K and PSQI-K scores were 18.1 ± 2.6 and 12.0 ± 2.2, respectively. Pearson correlation analysis showed a negative correlation between age of onset and ISI-K score and positive correlations between BRPS and PSQI-K scores and between K-ASI and both ISI-K and PSQI-K scores. Multiple regression analyses for both ISI-K and PSQI-K with K-ASI, age of onset, and BPRS as covariates revealed K-ASI as the only significant remaining factor. CONCLUSION: Our study suggests that anxiety symptoms are associated with insomnia symptoms in schizophrenia patients regardless of depressive or psychotic symptoms.

Transient hyperammonemia in a newborn is an overwhelming disease manifested by hyperammonemic coma. The majority of affected newborns are premature and have mild respiratory syndrome. The diagnosis may be difficult to determine. This metabolic disorder is primarily characterized by severe hyperammonemia in the postnatal period, coma, absence of abnormal organic aciduria and normal activity of the enzymes of the urea cycle. Hyperammonemic coma may develop within 2-3 days of life, although its etiology is unknown. Laboratory studies reveal marked hyperammonemia (>4,000 micromol/L). The degree of neurologic impairment and developmental delay in this disorder depends on the duration of hyperammonemic coma. Moreover, the infant may succumb to the disease if treatment is not started immediately and continued vigorously. Hyperammonemic coma as a medical emergency requires dialysis therapy. Here, we report a case of severe transient hyperammonemia in a preterm infant (35 week of gestation) presented with respiratory distress, seizure, and deep coma within 48 hours and required ventilatory assistance and marked elevated plasma ammonia levels. He survived with aggressive therapy including peritoneal dialysis, and was followed 2 years later without sequelae.

PURPOSE: To report a case of Joubert syndrome associated with Leber's congenital amaurosis. CASE SUMMARY: A 7-month-old boy was referred for poor eye contact and esodeviation since birth. He could not fixate with his eyes or follow objects. Nystagmus in both eyes and moderate angle esotropia were present. Slit lamp examination and fundus examination showed no significant findings. Visual evoked potential and electroretinogram were extinguished in both eyes. The patient showed abnormal respiratory patterns, developmental delay, and hypotonia. Brain MRI showed aplasia of the cerebellar vermis, and he was diagnosed with Joubert syndrome. At 2 years of age, he was moderately able to fixate with his eyes and to crudely follow objects. Nystagmus and esotropia had diminished, but the visual evoked potential and electroretinogram still showed no response in both eyes. CONCLUSIONS: Leber's congenital amaurosis can be associated with Joubert syndrome, and children with Leber's congenital amaurosis should be evaluated for associated systemic abnormalities.

Purpose: We aimed to analyze the clinical characteristics, recurrence, neurological outcomes, and the impact of coronavirus disease 2019 pandemic in children who visited 2 emergency departments (EDs) with febrile seizure (FS). Methods: We retrospectively reviewed medical records of 3,172 episodes, involving 2,510 children aged 6-60 months whose diagnoses were FSs at the EDs in 2 hospitals from 2013 through 2022. Through the review, we analyzed clinical characteristics and associated factors for the recurrence of FS. As a sub-analysis, the variables were compared between before (2017-2019) and during (2020-2022) the pandemic. Results: A total of 3,172 FS-related visits to the EDs were found in 2,510 children. Of these, 890 children (35.5%) underwent recurrences of FS. The recurrence of FS was associated with boys (63.3% vs. 57.8%; P = 0.007), seizures lasting longer than 5 minutes (16.6% vs. 12.7%; P = 0.007), family history of FS (23.7% vs. 16.2%; P < 0.001), complex FS (13.3% vs. 8.0%; P < 0.001), and epilepsy diagnosed thereafter (9.1% vs. 3.0%; P < 0.001). During the pandemic, we noted a decrease in the number of FS-related visits to the EDs (from 1,274 to 383), an increase in the percentage of complex FS (9.3% vs. 13.8%; P = 0.012), and a decrease in the percentage of recurrent FS (49.4% vs. 33.4%; P < 0.001), compared to before the pandemic. Conclusion Our study identified factors associated with recurrence of FS, and confirmed the increase in complex FS with the decrease in the recurrence during the coronavirus disease 2019 pandemic. These findings could be helpful when caring for children with FS in EDs.

PURPOSE: To evaluate the efficacy and safety of vitreoretinal surgery using a 23-gauge transconjunctival sutureless vitrectomy (TSV) system for various vitreoretinal diseases. METHODS: A retrospective, consecutive, interventional case series was performed for 40 eyes of 40 patients. The patients underwent vitreoretinal procedures using the 23-gauge TSV system, including idiopathic epiretinal membrane (n=7), vitreous hemorrhage (n=11), diabetic macular edema (n=10), macular hole (n=5), vitreomacular traction syndrome (n=5), diabetic tractional retinal detachment (n=1), and rhegmatogenous retinal detachment (n=1). Best corrected visual acuity (BCVA), intraocular pressure (IOP), and intra- and post-operative complications were evaluated. RESULTS: Intraoperative suture placement was necessary in 3 eyes (7.5%). The median BCVA improved from 20/400 (LogMAR, 1.21+/-0.63) to 20/140 (LogMAR, 0.83+/-0.48) at 1 week (p=0.003), 20/100 (LogMAR, 0.85+/-0.65) at 1 month (p=0.002), 20/100 (LogMAR, 0.73+/-0.6) at 3 months (p=0.001). In 1 eye, IOP was 5 mmHg at 2 hours and 4 mmHg at 5 hours, but none of the eyes showed hypotony after 1 postoperative day. No serous postoperative complications were observed during a mean follow-up of 8.4+/-3.4 months (range 3-13 months) CONCLUSIONS: The 23-gauge TSV system shows promise as an effective and safe technique for a variety of vitreoretinal procedures. It appears to be a less traumatic, more convenient alternative to 20-gauge vitrectomy in some indications.

Intraoperative pulmonary embolism can result in severe hemodynamic instability, including cardiac arrest. Therefore, immediate diagnosis and proper treatment are required. We report a case of the acute cardiac and pulmonary embolisms during radical nephrectomy and inferior vena cava (IVC) thrombectomy in a patient with renal cell carcinoma with thrombus in the IVC. We diagnosed the cardiac embolism intraoperatively using the transesophageal echocardiogram, and performed emergent cardiac and pulmonary embolectomies immediately. After the surgery, the patient was discharged without any complication.

OBJECTIVES: The purpose of the present in vitro study was to evaluate the biocompatibility of mineral trioxide aggregate (MTA) mixed with glass ionomer cement (GIC), and to compare it with that of MTA, GIC, IRM and SuperEBA. MATERIALS AND METHODS: Experimental groups were divided into 3 groups such as 1 : 1, 2 : 1, and 1 : 2 groups depending on the mixing ratios of MTA powder and GIC powder. Instead of distilled water, GIC liquid was mixed with the powder. This study was carried out using MG-63 cells derived from human osteosarcoma. They were incubated for 1 day on the surfaces of disc samples and examined by scanning electron microscopy. To evaluate the cytotoxicity of test materials quantitatively, XTT assay was used. The cells were exposed to the extracts and incubated. Cell viability was recorded by measuring the optical density of each test well in reference to controls. RESULTS: The SEM revealed that elongated, dense, and almost confluent cells were observed in the cultures of MTA mixed with GIC, MTA and GIC. On the contrary, cells on the surface of IRM or SuperEBA were round in shape. In XTT assay, cell viability of MTA mixed with GIC group was similar to that of MTA or GIC at all time points. IRM and SuperEBA showed significantly lower cell viability than other groups at all time points (p < 0.05). CONCLUSIONS: In this research MTA mixed with GIC showed similar cellular responses as MTA and GIC. It suggests that MTA mixed with GIC has good biocompatibility like MTA and GIC.

Plantar heel pain is common musculoskeletal disorder of the foot related to sports activity. Treatment of the plantar heel pain is usually conservative including low-dye (LD) taping. We evaluated the immediate clinical and biomechanical effect of LD taping. 19 patients who had plantar heel pain with fat pad tenderness or tenderness on plantar fascia insertion area participated in this study. We assessed plantar pressure change with foot pressure analysis system, fat pad depth changes with ultrasonography, pain improvement with visual analogue scale before and after LD taping. Patient treated with LD taping showed the decrease in maximum peak pressure and pressure time integral, and there was not a significant difference between pre and post maximal velocity, average velocity, distance of center of pressure. Fat pad depth increase (mean 1.67 mm, p<0.05) and pain improvement (mean 1.91 on visual analog scale, p<0.05). LD taping restrict midtarsal joint, correct hindfoot pronation, and provide fat pad depth increase and pain improvement, immediately.
