As the number of young cancer survivors increases, quality of life after cancer treatment is becoming an ever more important consideration. According to a report from the American Cancer Society, approximately 810,170 women were diagnosed with cancer in 2015 in the United States. Among female cancer survivors, 1 in 250 are of reproductive age. Anticancer therapies can result in infertility or sterility and can have long-term negative effects on bone health, cardiovascular health as a result of reproductive endocrine function. Fertility preservation has been identified by many young patients diagnosed with cancer as second only to survival in terms of importance. The development of fertility preservation technologies aims to help patients diagnosed with cancer to preserve or protect their fertility prior to exposure to chemo- or radiation therapy, thus improving their chances of having a family and enhancing their quality of life as a cancer survivor. Currently, sperm, egg, and embryo banking are standard of care for preserving fertility for reproductive-age cancer patients; ovarian tissue cryopreservation is still considered experimental. Adoption and surrogate may also need to be considered. All patients should receive information about the fertility risks associated with their cancer treatment and the fertility preservation options available in a timely manner, whether or not they decide to ultimately pursue fertility preservation. Because of the ever expanding number of options for treating cancer and preserving fertility, there is now an opportunity to take a precision medicine approach to informing patients about the fertility risks associated with their cancer treatment and the fertility preservation options that are available to them.

Background: Interleukin (IL)-17 and IL-23 inhibitors have helped achieve clear skin in many patients with psoriasis. However, real-world data to compare short- and long-term efficacy of these biologics in Korean patients are lacking. Objective: To compare short- and long-term efficacy of IL-17A and IL-23 inhibitors in patients with moderateto-severe psoriasis. Methods: We retrospectively evaluated efficacy of IL-17A and IL-23 inhibitors among patients treated at Ajou University Hospital from 2017 to 2022. The specific agents studied were as follows: secukinumab, 32 patients; ixekizumab, four patients; guselkumab, 13 patients; and risankizumab, 31 patients. Patients who were followed up for less than a year or changed biologics were excluded. Results: The rates of psoriasis area and severity index (PASI) 90 achievement of secukinumab were 62.5%, 86.7%, 89.3%, 80.8%, and 70.8% at weeks 16, 40, 88, 112, and 136, respectively. For ixekizumab, the PASI90 achievement rates were 75%, 100%, 75%, and 100% at weeks 16, 40, 64, and 88, respectively. The PASI90 achievement rates of guselkumab were 53.8%, 76.9%, 72.7%, and 77.8% at weeks 20, 44, 68, and 92, respectively. For risankizumab, PASI90 achievement rates were 69.7%, 90.0%, 93.7%, and 100% at weeks 28, 52, 76, and 100, respectively. Before 52 weeks, PASI90 achievement was significantly lower with guselkumab than with secukinumab (hazardratio=0.22). After 52 weeks, PASI90 achievement was significantly higher with risankizumab than with secukinumab (hazard ratio=2.00). Conclusion PASI90 was achieved faster with IL-17A inhibitors than with IL-23 inhibitors. However, IL-23 inhibitors afforded the maintenance of a higher PASI score after 52 weeks.

Chordoid glioma is a rare low grade tumor typically located in the third ventricle. Although a chordoid glioma can arise from ventricle with tumor cells having features of ependymal differentiation, intraventricular dissemination has not been reported. Here we report a case of a patient with third ventricular chordoid glioma and intraventricular dissemination in the lateral and fourth ventricles. We described the perfusion MR imaging features of our case different from a previous report.

Background: Patients with hematologic cancers have a risk of drug-related problems (DRPs) from medications associated with chemotherapy and supportive care. Although the role of oncology pharmacists has been widely documented in the literature, few studies have reported its impact on cost reduction. This study aimed to describe the activities of oncology pharmacists with respect to hematologic diseases and evaluate the associated cost avoidance. Methods: From January to July 2021, patients admitted to the department of hemato-oncology at Seoul National University, Bundang Hospital were studied. The activities of oncology pharmacists were reported by DRP type following the Pharmaceutical Care Network version 9.1 guidelines, and the acceptance rate was calculated. The avoided cost was estimated based on the cost of the pharmacy intervention, pharmacist manpower, and prescriptions associated with the intervention. Results: Pharmacists intervened in 584 prescriptions from 208 patients during the study period. The most prevalent DRP was “adverse drug event (possibly) occurring” (32.4%), followed by “effect of drug treatment not optimal” (28.6%). “Drug selection” (42.5%) and “dose selection” (30.3%) were the most common causes of DRPs. The acceptance rate of the interventions was 97.1%. The total avoidance cost was KRW 149,468,321; the net profit of the avoidance cost, excluding labor costs, was KRW 121,051,690; and the estimated cost saving was KRW 37,223,748. Conclusion Oncology pharmacists identified and resolved various types of DRPs from prescriptions for patients with hematologic disease, by reviewing the prescriptions. Their clinical service contributed to enhanced patient safety and the avoidance of associated costs.

PURPOSE: Despite the increasing use of continuous renal replacement therapy (CRRT) in the neonatal intensive care unit (NICU), few studies have investigated its use in preterm infants. This study evaluated the prognosis of preterm infants after CRRT and identified risk factors of mortality after CRRT. MATERIALS AND METHODS: A retrospective review was performed in 33 preterm infants who underwent CRRT at the NICU of Samsung Medical Center between 2008 and 2017. Data of the demographic characteristics, predisposing morbidity, cardiopulmonary function, and CRRT were collected and compared between surviving and non-surviving preterm infants treated with CRRT. Univariable and multivariable analyses were performed to identify factors affecting mortality. RESULTS: Compared with the survivors, the non-survivors showed younger gestational age (29.3 vs. 33.6 weeks), lower birth weight (1359 vs. 2174 g), and lower Apgar scores at 1 minute (4.4 vs. 6.6) and 5 minutes (6.5 vs. 8.6). At the initiation of CRRT, the non-survivors showed a higher incidence of inotropic use (93% vs. 40%, p=0.017) and fluid overload (16.8% vs. 4.0%, p=0.031). Multivariable analysis revealed that fluid overload >10% at CRRT initiation was the primary determinant of mortality after CRRT in premature infants, with an adjusted odds ratio of 14.6 and a 95% confidence interval of 1.10–211.29. CONCLUSION: Our data suggest that the degree of immaturity, cardiopulmonary instability, and fluid overload affect the prognosis of preterm infants after CRRT. Preventing fluid overload and earlier initiation of CRRT may improve treatment outcomes.

BACKGROUND: To investigate the incidence of surgical intervention in very low birth weight (VLBW) infants and the impact of surgery on neurodevelopmental outcomes at corrected ages (CAs) of 18–24 months, using data from the Korean Neonatal Network (KNN). METHODS: Data from 7,885 VLBW infants who were born and registered with the KNN between 2013 to 2016 were analyzed in this study. The incidences of various surgical interventions and related morbidities were analyzed. Long-term neurodevelopmental outcomes at CAs of 18–24 months were compared between infants (born during 2013 to 2015, n = 3,777) with and without surgery. RESULTS: A total of 1,509 out of 7,885 (19.1%) infants received surgical interventions during neonatal intensive care unit (NICU) hospitalization. Surgical ligation of patent ductus arteriosus (n = 840) was most frequently performed, followed by laser therapy for retinopathy of prematurity and laparotomy due to intestinal perforation. Infants who underwent surgery had higher mortality rates and greater neurodevelopmental impairment than infants who did not undergo surgery (P value < 0.01, both). On multivariate analysis, single or multiple surgeries increased the risk of neurodevelopmental impairment compared to no surgery with adjusted odds ratios (ORs) of 1.6 with 95% confidence interval (CI) of 1.1–2.6 and 2.3 with 95% CI of 1.1–4.9. CONCLUSION: Approximately one fifth of VLBW infants underwent one or more surgical interventions during NICU hospitalization. The impact of surgical intervention on long-term neurodevelopmental outcomes was sustained over a follow-up of CA 18–24 months. Infants with multiple surgeries had an increased risk of neurodevelopmental impairment compared to infants with single surgeries or no surgeries after adjustment for possible confounders.

Purpose: We aimed to compare two different sedation protocols for brain magnetic resonance imaging (MRI) in preterm infants. One protocol used chloral hydrate (CH) with monitoring conducted by non-anesthesiologists, and the other used a continuous infusion of propofol (PF) with monitoring by anesthesiologists. Methods: A total of 250 preterm infants born between January 2011 and December 2015 who received brain MRI during hospitalization in our neonatal intensive care unit (NICU) were included in this retrospective study. In period 1, sedation for brain MRI was done using a single dose or multiple doses of CH with monitoring conducted by NICU medical staff. In period 2, an anesthesiologist prescribed a continuous infu­sion of PF and titrated the dosage for minimal and adequate sedation. Data on the adverse events, including desaturation and bradycardia, were collected and compared between periods 1 and 2. Results: Despite similar gestational ages of the patients in periods 1 and 2, the infants in period 1 showed a higher risk of developing bradycardia after sedation compared to those in period 2 (30.2% vs. 14.8%; an adjusted odds ratio of 2.35; 95% confidence interval of 1.12 to 4.91). Infants who had an adverse event after sedation had a lower gestational age and corrected age at the time of MRI (26.8 weeks vs. 27.9 weeks, P=0.004; 37.3 weeks vs. 38.3 weeks, P=0.023). The duration of MRI was significantly longer in infants that had an adverse event than those that did not (70.9 minutes vs.64.3 minutes). After adju­sting for various clinical factors, lower gestational age, lower corrected age at the time of MRI, and period 1 increased the risk of developing adverse events after sedation for MRI. Conclusion The use of a continuous PF infusion with dose titration and monitoring by an anesthesiologist is safe and feasible as a sedation protocol for brain MRI in prematurely born infants.

Purpose: To compare respiratory outcomes between less invasive surfactant admi nistration (LISA) and the intubation-surfactant-extubation (INSURE) technique in premature infants with respiratory distress syndrome (RDS). Methods: We performed a retrospective medical chart review for 75 premature in fants who were born at a gestational age (GA) of ≤34 weeks (between January 2017 and December 2019) and developed RDS after birth. Data on the demographic and outcome variables, including respiratory outcomes, were collected and compared between the infants who received LISA and those who received INSURE as a rescue therapy for RDS. Results: No signifcant differences in GA, birth weight, and other demographic characteristics were found between the LISA and INSURE groups (GA: 28.7 weeks vs.28.8 weeks, P=0.449; birth weight: 1,236 g vs. 1,124 g, P=0.714). At the delivery room, although the infants showed no significant difference in positive pressure ventilation rate after birth, the LISA group showed a higher rate of continuous positive airway pressure application than the INSURE group. The infants in the LISA group presented a higher risk of requiring multiple doses of surfactant for RDS than the infants in the INSURE group (57% vs. 17.5%, P=0.001). However, the duration of invasive and/ or noninvasive respiratory support and incidence of bronchopulmonary dysplasia showed no signifciant difference between the two groups. Conclusion In the present study, no significant differences in the incidence of inhospital respiratory outcomes such as bronchopulmonary dysplasia were found between the LISA and INSURE groups. These results suggest that LISA can be an alternative therapeutic option for treating RDS to avoid intubation and mechanica ventilation in premature infants.

OBJECTIVE: The use of computed tomography (CT) in pediatric patients has decreased since the association between radiation and cancer risk has been reported. However, in adolescent patients being treated as adult patients, there has been a high incidence of CT use in emergency departments (EDs). Thus, this study aimed to evaluate the CT use in adolescent patients with complaints of headache or abdominal pain in the general and pediatric EDs of the same hospital.METHODS: A retrospective chart review of patients aged 15 to 18 years, who presented with headache or abdominal pain at the general and pediatric EDs of Seoul National University Hospital from January 2010 to December 2014, was conducted.RESULTS: A total of 407 adolescent patients with complaints of headache and 980 with abdominal pain were included in this study. The adolescent patients in the general ED were more likely to undergo CT scans than those in the pediatric ED, with both patients having headache (42.4% vs. 20.5%, respectively, P<0.001) and abdominal pain (29.0% vs. 18.4%, respectively, P<0.001). There was no statistical difference in the rates of positive CT findings between the general and pediatric EDs. The frequency of visits to the general ED was associated with high rates of CT use in adolescent patients with complaints of headache (odds ratio, 3.95; 95% confidence interval, 2.01 to 7.77) and those with abdominal pain (odds ratio, 1.76; 95% confidence interval, 1.18 to 2.64).CONCLUSION: The ED setting influences the use of CT on adolescent patients, and a child-friendly environment could reduce the radiation risks.
