PURPOSE: In the field of pediatric surgery, neonatal surgery occupies a special portion and has clinical varieties. Recently many associated physicians, such as pediatric surgeons, neonatologists, anesthetists, pathologists and radiologists, work collaboratively for care. This study was designed to identify characteristics of neonatal surgery based on clinical experiences in a single institute. METHODS: Neonates receiving operation during a 5-year period between Jan. 2003 and Dec. 2007 in Pusan National University Children's Hospital were reviewed. Patients were divided into 2 groups of age after birth; early neonatal (before 7 days) and late neonatal period (after 7 days) and the operation was classified as a primary procedure for definite treatment and a staged procedure including 2nd look operation. We analyzed their clinical data and postoperative results. RESULTS: 286 cases of neonates were included during this period, 118 cases (41.3%) in early neonatal and 168 (58.7%) in late neonatal period. Distribution of diseases was as follows, sequentially; 60 (21.0%) anorectal malformations, 46 (16.1%) intestinal atresia, 44 (15.4%) Hirschsprung's disease, 35 (12.2%) necrotizing enterocolitis, 24 (8.3%) hypertrophic pyloric stenosis, 20 (6.9%) inguinal hernia, 13 (4.5%) malrotation, 9 (3.1%) tumor, 8 (2.7%) diaphragmatic hernia, 6 (2.0%) abdominal wall defect and 21 (7.3%) others. According to the operation, a primary procedure was performed in 205 cases (71.7%) and a staged procedure in 81 cases (28.3%). The morbidity and mortality was 3.1% and 2.8% respectively. CONCLUSION: When considering morbidity and mortality after neonatal surgery for patients who have associated anomalies, collaborative care is necessary to expect a good outcome.

Purpose:
Methotrexate (MTX) is an immunosuppressive agent used to treat noninfectious inflammatory eye conditions and is generally administered orally for ocular inflammatory diseases. When used in rheumatological diseases, subcutaneous administration has been reported to show higher efficacy than oral administration. Therefore, this study aimed to evaluate the effect of subcutaneous MTX in patients with refractory uveitis or choroiditis who did not respond to other immunosuppressive agents.
Methods:
A retrospective case series study was performed between January and December 2018. Patients with uveitis or chorioretinitis who showed little to no treatment response for 6 months or more with conventional immunosuppressive agents were treated with MTX, administered subcutaneously. After 6 months of treatment, patients were evaluated to determine whether complete suppression of inflammation sustained for ≥28 days was achieved in both eyes and whether improvement can be confirmed by fluorescein angiography (FAG).
Results:
Subcutaneous MTX treatment was performed on 18 patients: 11 had intermediate uveitis and seven had posterior uveitis. In the intermediate uveitis patient group, five patients (50% of the group excluding one patient who dropped out) showed improvement in FAG and three patients (30%) showed complete suppression of inflammation. In the posterior uveitis group, two out of seven patients (excluding two patients who dropped out) showed an improvement, two patients in the group showed little change, and one patient showed aggravation of FAG findings.
Conclusions
The study confirmed that in patients with uveitis or chorioretinitis who had a refractory response to treatment with other immunosuppressive agents, subcutaneous MTX showed improved treatment efficacy.

OBJECTIVE: To evaluate whether computed tomography (CT) reconstruction algorithms affect the CT texture features of the liver parenchyma. MATERIALS AND METHODS: This retrospective study comprised 58 patients (normal liver, n = 34; chronic liver disease [CLD], n = 24) who underwent liver CT scans using a single CT scanner. All CT images were reconstructed using filtered back projection (FBP), hybrid iterative reconstruction (IR) (iDOSE4), and model-based IR (IMR). On arterial phase (AP) and portal venous phase (PVP) CT imaging, quantitative texture analysis of the liver parenchyma using a single-slice region of interest was performed at the level of the hepatic hilum using a filtration-histogram statistic-based method with different filter values. Texture features were compared among the three reconstruction methods and between normal livers and those from CLD patients. Additionally, we evaluated the inter- and intra-observer reliability of the CT texture analysis by calculating intraclass correlation coefficients (ICCs). RESULTS: IR techniques affect various CT texture features of the liver parenchyma. In particular, model-based IR frequently showed significant differences compared to FBP or hybrid IR on both AP and PVP CT imaging. Significant variation in entropy was observed between the three reconstruction algorithms on PVP imaging (p < 0.05). Comparison between normal livers and those from CLD patients revealed that AP images depend more strongly on the reconstruction method used than PVP images. For both inter- and intra-observer reliability, ICCs were acceptable (> 0.75) for CT imaging without filtration. CONCLUSION: CT texture features of the liver parenchyma evaluated using the filtration-histogram method were significantly affected by the CT reconstruction algorithm used.

Objectives:
:The purpose of this study was to investigate the needs for return-to-work support of cancer survivors and related factors in patients with cancer and their caregivers.
Methods:
:182 patients and 114 caregivers were recruited. Distress Thermometer and Problem List and scale ranging 0~10 measuring the degree of needs for return-to-work support were utilized. The needs for return-towork support between the patient group and caregiver group (patient’s needs evaluated by the caregiver) were compared, and related factors were investigated using logistic regression analysis.
Results:
:34.6% and 28.1% of patients and caregivers reported return-to-work support of cancer survivors is “very necessary”. The degree of needs was 6.60±3.365 points in the patient group and 6.17±3.454 points in the caregiver group, with no significant difference (p=0.282). The needs for return-to-work support evaluated by patients was high when they underwent surgery (OR=2.592, p=0.007), has fertility problems (OR=6.137, p=0.025), has appearance problems (OR=2.081, p=0.041), or has fatigue (OR=2.330, p=0.020). The needs for return-towork support of patients evaluated by caregivers was high when patients treated with breast cancer (vs respiratory cancer, OR=13.038, p=0.022 ; vs leukemia/lymphoma, OR=4.517, p=0.025 ; vs other cancer, OR=13.102, p= 0.019), has work/school problems (OR=4.578, p=0.005), or has depression (OR=3.213, p=0.022).
Conclusions
:The degree of needs for return-to-work support of cancer survivors was high, and factors related to the needs were different between the two groups. This suggests that return-to-work support of cancer survivors is required, and clinical characteristics, the distress of patients, and differences between patients and their caregivers should be considered in establishing a support plan.

Objective:
Previous studies have reported an association between cancer-related symptoms and perceived social support (PSS). The objective of this study was to analyze whether Chemotherapy-Induced Peripheral Neuropathy (CIPN), a prevalent side effect of chemotherapy, varies according to PSS level using a validated tool for CIPN at prospective follow-up.
Methods:
A total of 39 breast cancer patients were evaluated for PSS using the Multidimensional Scale of Perceived Social Support (MSPSS) prior to chemotherapy and were subsequently grouped into one of two categories for each subscale: low-to-moderate PSS and high PSS. CIPN was prospectively evaluated using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy 20 (CIPN20) at five time points. A linear mixed-effects model with square root transformation was employed to investigate whether the CIPN20 scales varied by PSS level and time point.
Results:
Statistical analysis of the MSPSS total scale and subscales revealed a significant effect of the friends subscale group and time point on the CIPN20 sensory scale. The sensory scale score of CIPN20 was found to be lower in participants with high PSS from friends in comparison to those with low-to-moderate PSS at 1 month post-chemotherapy (p=0.010).
Conclusion
This is the first study to prospectively follow the long-term effect of pre-treatment PSS from friends on CIPN. Further studies based on larger samples are required to analyze the effects of PSS on the pathophysiology of CIPN.
