Anticancer drugs kill tumor cells and increase host anti-tumor immunity. Interestingly, gemcitabin (Gem) and 5-fluorouracil (5-FU), widely used anticancer drugs, lead to IL-1beta secretion releasing cathepsin B which activates Nlrp3 inflammasome in myeloid derived suppressor cells (MDSCs). MDSC derived IL-1beta enhance secretion of IL-17 by CD4+ T cells. This mechanism limits the antitumor efficacy of the drugs and promotes tumor growth.

PURPOSE: This study was performed to examine parenting attitude and stress according to personality type in elementary school students' mothers. METHODS: The subjects consisted of 206 mothers of students. The measurement instrument was the questionnaire consisting of Korean-version MBTI and PSI test. Data was collected from March 15th to April 15th, 2008. RESULTS: Among personality types by function, ST type was most, occupying 60.2%. Among personality types by temperament, SJ type was most, occupying 59.2%. The score of affective attitude was highest among the parenting attitudes. Parenting attitude was significantly different according to age, education, economic status, number of children, planned pregnancy, factor of stress, and family type. Parenting stress was significantly different according to planned pregnancy and factor of stress. In parenting attitudes by personality types, affective attitude was significantly different. Parenting stress was significantly different according to personality type by function. There was a negative correlation between affective and autonomic attitudes and parenting stress. There was a positive correlation between rejective attitude and parenting stress. CONCLUSION: It would be essential to provide dynamic developmental programs for increasing the children's social ability, and nursing intervention, education and counseling programs for decreasing parenting stress through understanding mothers' personality type.

Background & Objectives: To determine the prevalence and characteristics of radiculopathy in
Parkinson’s disease (PD) patients through electrodiagnostic tests, to assess associated radicular pain
characteristics,and to investigate the relationship between pain and other clinical manifestations of PD.
Methods: Electrodiagnostic testing including nerve conduction studies and needle electromyographywas
performed to investigate comorbid peripheral neuropathy or radiculopathy. All patients were asked
to complete aquality of life (QOL) measurement related to pain. Results: Thirty-two (39%) of 82
PD patients had radiculopathy based on electrodiagnostic testing. 46.9% with radiculopathy patients
had involvement of multiple roots level. The most commonly involved root was L5 (83.3%). Patients
with radiculopathy had longer PD durations (p=0.011) and higher posture-related axial scores on the
UPDRS scale (p=0.017).There was a trend for pain in the leg and low back to occur more frequently
in PD patients with radiculopathy. QOL is not significantly different according to the presence of
radiculopathy in PD.
Conclusions: This study demonstrates a high prevalence of radiculopathy, particularly multiple root
involvement, and is correlated with pain complaints and with axial motor scores on UPDRS. These
findings might be related to increased shear force at the intervertebral disc by axial rigidity and flexed
posture in PD along with the duration and severity of PD disease course.

Sedation plays a crucial role in successful pediatric imaging, and chloral hydrate is commonly used for this purpose. However, the challenges associated with chloral hydrate administration, such as its unpleasant taste and potential induction of vomiting, remain a concern. Sweet oral solutions have emerged as potential solutions for reducing distress and providing analgesia. This study compared the efficacy of dextrose combined with chloral hydrate with that of conventional sedation methods. This prospective, double-blind, randomized controlled clinical study enrolled 160 pediatric outpatients scheduled for echocardiography. Chloral hydrate syrup (100 mg/mL) was supplemented with a dextrose solution (dextrose group) or distilled water (control group) in a 1:10 volume ratio. The sedation achievement time, Skeie scale score, revised Face, Legs, Activity, Cry, and Consolability (FLACC) score, and side effects (nausea, vomiting, hypoxia, and respiratory depression) were assessed. No significant difference in average time to achieve sedation was observed between the dextrose and control groups (24.4±17.8 vs. 24.7±17.1 min, p=0.92). Both groups demonstrated similar levels of sedation according to the Skeie scale and mean revised FLACC score. Although the occurrence rates of nausea and vomiting had no significant differences, the dextrose group had no cases of vomiting in children aged >24 months compared to the control group, which had three cases (30%). In conclusion, the addition of dextrose to chloral hydrate did not significantly affect sedation time, anxiety, pain reduction, or occurrence of gastrointestinal complications during sedation.

Dural arteriovenous fistula (DAVF) of anterior cranial fossa is a rare entity. The authors report a 57 year-old man presented with retro-orbital headache caused by a large hematoma in the right frontal lobe. Angiography demonstrated a DAVF of anterior cranial fossa fed by branches of middle meningeal and anterior ethmoidal artery. Endovascular therapy using N-butyl cyanoacrylate was tried, however, was failed to occlude the fistula. After than, the lesion was successfully obliterated by surgical means. The therapeutic roles and pitfalls of endovascular treatment and surgical treatment for the anterior fossa DAVF are discussed.

Background:
Aggressive mature B-cell non-Hodgkin lymphoma (B-NHL) is the most common non-Hodgkin lymphoma in children. The outcome of chemotherapy for B-NHL has improved over decades.
Methods:
We reviewed 82 children and adolescents with B-NHL diagnosed at Asan Medical Center between 1993 and 2020. The D-COMP/COMP (daunomycin–cyclophosphamide, doxorubicin, vincristine, and prednisolone), Pediatric Oncology Group (POG)-9219/9315/ 9317, R-CHOP/CHOP (rituximab–cyclophosphamide, doxorubicin, vincristine, and prednisolone), and Lymphomes Malins B 89 (LMB89)/LMB96 regimens were administered. In 2018, rituximab was added to the LMB protocol (R-LMB) for advanced-staged Burkitt lymphoma (BL). The patients’ clinical features and treatment outcomes were retrospectively analyzed.
Results:
The most common subtype was BL (61%), followed by diffuse large B-cell lymphoma (DLBCL) (35%). The median age was 7.8 (range, 1.3‒16.4) years, and the most frequently used regimen was French‒American‒British (FAB)/LMB96 (58 patients, 70.7%). The 5-year overall survival (OS) and event-free survival (EFS) rates were 92.5% and 85.7%, respectively. The EFS rates of patients with BL and DLBCL were 90.0% and 79.3%, respectively. Among the FAB/LMB risk groups, group C (85.7%) had a significantly lower 5-year OS (P =0.037). Eleven events occurred (6 relapses, 3 deaths, and 2 secondary malignancies) during the median follow-up of 7.1 (range, 3.7‒118.5) months. Two patients treated with R-LMB had good outcomes without complications.
Conclusion
Various treatment regimens have favorable outcomes in pediatric patients with B-NHL.However, further studies are needed to improve survival in high-risk patients. In addition, careful monitoring for acute toxicity or secondary malignancy due to intensive multidrug chemotherapy is required.
