2.Management of hepatocellular carcinoma in elderly and adolescent/young adult populations
Journal of Liver Cancer 2025;25(1):52-66
Hepatocellular carcinoma (HCC) presents unique challenges in both the elderly and adolescent/young adult (AYA) populations, requiring distinct management approaches. Recent epidemiological data show an increasing incidence of HCC in both age groups, with elderly cases rising significantly and AYA cases showing trends in specific regions. The clinical characteristics and treatment considerations vary substantially among these populations. Elderly patients with HCC typically present with hepatitis C virus infection, metabolic dysfunction-associated steatotic liver disease, well-differentiated tumors, and multiple comorbidities. In contrast, AYA patients with HCC often present with more aggressive tumor characteristics and predominantly with hepatitis B virus-related diseases. Treatment decisions for elderly patients with HCC require careful consideration of physiological reserves, comprehensive geriatric assessments, and potential complications. Recent studies have demonstrated that elderly patients can achieve outcomes comparable to younger patients across various treatment modalities when properly selected. While surgical outcomes are comparable to those of younger patients with proper selection, less-invasive options such as radiofrequency ablation or transarterial therapies may be more appropriate for some elderly patients. The treatment approach for AYA HCC emphasizes curative intent while considering long-term effects. AYA patients require specialized attention to their psychosocial needs, fertility preservation, and long-term health maintenance. Although data on AYA patients remain limited, they are known to have relatively favorable prognoses despite exhibiting more aggressive tumor characteristics. Management of HCC in both the elderly and AYA populations requires individualized approaches that consider age-specific factors. Both groups benefit from multidisciplinary team involvement and careful consideration of quality of life.

Background/Aims:
Distal mean nocturnal baseline impedance (MNBI) measuring via pH-impedance may be valuable in diagnosing patients with suspected laryngopharyngeal reflux (LPR). However, its wide adoption is hindered by cost and invasiveness. This study investigates whether baseline impedance measured during high-resolution impedance manometry (HRIM-BI) can predict pathological MNBI.
Methods:
A cross-sectional study in Taiwan included 74 subjects suspected of LPR, who underwent HRIM (MMS) and pH-impedance testing (Diversatek), after stopping proton pump inhibitors for more than 7 days. Subjects with grade C or D esophagitis or Barrett’s esophagus were excluded. The cohort was divided into 2 groups: those with concomitant typical reflux symptoms (CTRS, n = 28) and those with isolated LPR symptoms (ILPRS, n = 46). HRIM-BI measurements focused on both distal and proximal esophagi. Pathological MNBI was identified as values below 2065 Ω, measured 3 cm above the lower esophageal sphincter.
Results:
In all subjects, distal HRIM-BI values correlated weakly with distal MNBI(r = 0.34-0.39, P < 0.005). However, in patients with ILPRS, distal HRIM-BI corelated moderately with distal MNBI(r = 0.43-0.48, P < 0.005). The areas under the receiver operating characteristic curve was 0.78 (P = 0.001) with a sensitivity of 0.83 and a specificity of 0.68. No correlation exists between distal HRIM-BI and distal MNBI in patients with CTRS, and between proximal HRIM-BI and proximal MNBI in both groups.
Conclusions
Distal HRIM-BI from HRIM may potentially predict pathological MNBI in patients with ILPRS, but not in those with CTRS. Future outcome studies linked to the metric are warranted.

Journal of the Korean Academy of Child and Adolescent Psychiatry 2025;36(2):54-61
Objectives:
Digital therapeutics are becoming increasingly important in mental health due to their numerous advantages. One area that could benefit significantly is parenting education. To address this, we developed a short-term, smartphone-based parenting education program designed to support parents who lack access to relevant resources. This study analyzed baseline data from participants to identify factors influencing depressive symptoms in both parents and children.
Methods:
Participants were recruited from a rural region of the Republic of Korea. The study included parents experiencing stress related to raising children aged 11 to 16 years. Data on psychological well-being and family relationships were collected and analyzed from 47 parent-child dyads. Participants engaged with a six-week parenting education application aimed at reducing parenting stress. This article does not include an analysis of the intervention’s efficacy.
Results:
The child perceived their families as more chaotic compared their parents (t=-2.55, p=0.01). Parental depression was significantly associated with their stress levels (B=0.70, p=0.004), anxiety (B=0.32, p=0.03), relational frustration (B=0.16, p=0.04), family enmeshment (B=-0.13, p=0.04) and the child’s perception of family flexibility (B=0.10, p=0.04). In contrast, children’s depression was associated with lower self-esteem (B=-0.55, p=0.02) and aggression (B=0.23, p=0.01).
Conclusion
These findings highlight the importance of individualized parenting education programs, particularly those that address the specific needs of both parents and children. Digital therapeutics hold significant potential for providing accessible, evidence-based parenting support aimed at improving mental health outcomes in families.

Journal of the Korean Ophthalmological Society 2025;66(1):70-74
Purpose:
To present a case of recurrent Nocardia keratitis following the use of topical steroids.Case summary: A 57-year-old man presented with decreased visual acuity and conjunctival injection in the right eye which began 15 days prior. Slit-lamp examination revealed epithelial defects smaller than the circular infiltrate and empirical topical treatment was initiated. Since the corneal lesion improved with a therapeutic contact lens and topical antibiotics, a steroid eye drop was added. After 7 days, the corneal infiltrate worsened in a wreath-like pattern with a positive result on a KOH (potassium hydroxide) smear, and antifungal eye drops were started. However, Nocardia species was confirmed on the 9th day of culture. While complete epithelial regeneration was achieved after 10 days using amikacin eye drops, steroid eye drops were reused to reduce the corneal haze. Twenty days later, the corneal infiltrate and epithelial defects reappeared adjacent to the initial opacity, and a culture confirmed Nocardia. Gradual improvement was achieved with amikacin eye drops and oral Septrin. Ultimately, a combination of moxifloxacin, tobramycin, and bromfenac eye drops was tapered over several months, resulting in healing with mild opacity.
Conclusions
Nocardia keratitis commonly arises from trauma involving soil, progresses slowly, and is often misdiagnosed as a fungal infection. While amikacin eye drops proved effective, prolonged topical treatment is essential. Early steroid use should be considered cautiously, as it may lead to recurrence and worsening of the corneal lesion.

Korean Journal of Radiology 2025;26(4):324-332
Objective:
To compare coronary artery dimension-adjusted subtended myocardial mass between patients with hypertrophic cardiomyopathy (HCM) and a normal population without detectable atherosclerosis, and between HCM patients with and without chest pain.
Materials and Methods:
Twenty-five patients with HCM but no detectable atherosclerosis on coronary computed tomography angiography (CCTA) were included in the study. This group comprised 14 patients with chest pain and 11 patients without chest pain. They were matched with 25 healthy participants based on sex, age, coronary dominance pattern, and body surface area. The minimal lumen area (MLA) and subtended myocardial volume (V sub) were assessed in the left main (LM), proximal left anterior descending (pLAD), proximal left circumflex (pLCx), and proximal right coronary (pRCA) arteries. Additionally, an index of the subtended myocardial mass adjusted for the MLA, calculated as V sub/MLA 2 , was determined.
Results:
MLA was significantly larger in patients with HCM compared to the control group in LM (20.93 ± 6.31 mm 2 vs.15.24 ± 3.90 mm 2 , P< 0.001), pLAD (14.28 ± 3.55 mm 2 vs. 11.36 ± 2.07 mm 2, P = 0.001), pLCx (10.94 ± 3.60 mm 2 vs. 9.15 ± 2.93 mm 2 , P = 0.045), and pRCA (13.41 ± 4.85 mm 2 vs. 11.22 ± 3.20 mm 2 , P = 0.018). Despite an increase in coronary luminal area, patients with HCM exhibited significantly higher V sub/MLA 2 compared to the control group in both the pLAD (403.56 ± 200.35 mm -1 vs. 241.70 ± 85.87 mm -1 , P < 0.001) and the pRCA (186.06 ± 95.07 mm -1 vs. 125.07 ± 70.18 mm -1 , P= 0.007). V sub/MLA 2 was significantly elevated in patients with chest pain compared to those without in the pLAD (473.75 ± 227.38 mm -1 vs. 314.24 ± 110.74 mm -1 , P = 0.018) and the pLCx (417.04 ± 182.65 mm -1 vs. 275.29 ± 112.97 mm -1 , P = 0.044).
Conclusion
CCTA-derived V sub/MLA 2 may more accurately reflect the balance between myocardial blood supply and demand, offering insights into the occurrence of demand angina in patients with HCM without obstructive coronary artery disease.

Objective:
This study hypothesized that physical status, temperament and characteristics, and neurocognitive functions of basketball players could predict the result of Korean Basketball League (KBL) draft selection.
Methods:
We recruited the number of 89 college elite basketball players (KBL selection, n=44; non-KBL selection, n=45), and the number of 82 age-matched healthy comparison subjects who major in sports education in college. All participants were assessed with the Temperament and Character Inventory, Sports Anxiety Scales, Beck Depression Inventory, Perceived Stress Scale-10, Trail Making Test, and Computerized Neuro-cognitive Test for Emotional Perception and Mental Rotation.
Results:
Current results showed that physical status, temperament and characteristics, and neurocognitive functions of college basketball players could predict the KBL draft selection. Among temperament and characteristics, novelty seeking and reward dependence were associated with KBL draft selection. The basketball performances including average scores and average rebound were associated with Emotional Perception and Mental Rotation.
Conclusion
In order to be a good basketball player for a long time, it was confirmed that temperamental factors and neurocognitive factors were very closely related. Furthermore, it is also judged that these results can be used as basic data to predict potential professional basketball players.

Psychiatry Investigation 2025;22(5):574-582
Objective:
A humanities-based approach to understanding the brain can yield valuable insights, advancing neuroscience and enhancing mental, emotional, and social well-being. This study was aimed at exploring how engagement in literature-related activities stimulates brain activity in the prefrontal cortex.
Methods:
We recruited 24 healthy male participants aged 20 to 29 years. They completed clinical scales assessing depression, anxiety, attention, and humanistic knowledge. They also performed six tasks comprising various literature-related cognitive challenges while hemodynamic changes in their frontal cortices were measured using functional near-infrared spectroscopy.
Results:
Task 1 (word memory and recognition) increased activation in the ventrolateral prefrontal cortex (VLPFC), as did Task 2 (emotional words classification), which also elevated activity in the left orbitofrontal cortex (OFC). Task 3 (understanding context) increased activation in the dorsolateral PFC (DLPFC). Tasks 4 (interpersonal relationship) and 5 (listening, memory, understanding, and expression) drove similar increases in the frontopolar and DLPFC regions. Task 6 (creative activities using characters and items) significantly activated multiple regions, including the right and left VLPFC and OFC. Humanistic knowledge scores were positively correlated with left and right DLPFC activation in Tasks 3 and 5, respectively. Conversely, Task 6 showed negative correlations between attention-deficit/hyperactivity disorder scores and both right DLPFC and right OFC activation.
Conclusion
This study identified key brain regions involved in literature activities. Complex activities (semantic processing, understanding and creative expression, decision-making and emotional regulation, etc.) stimulated various regions of prefrontal cortices, including the VLPFC, DLPFC, and OFC.

This study aimed to evaluate the long-term efficacy and complication of radiotherapy for benign soft tissue tumors. Five cases of benign soft tissue tumors (two plexiform neurofibromas, two juvenile nasopharyngeal angiofibromas, and one cavernous sinus hemangioma) who underwent radiotherapy were enrolled. All patients had at least 10 years of follow-up. The median follow-up duration was 12 years (range, 10 to 27). Three patients underwent incomplete excision prior to radiotherapy. Radiation doses were either 54 Gy in 30 fractions or 50.4 Gy in 28 fractions (1.8 Gy per fraction). Every patient achieved complete remission (CR) or near-CR. The tumor volume decreased significantly within the first 2 years of follow-up and continued to decrease slowly up to 10 years; no distinct further decrease in tumor volume was observed after 10 years. One patient developed left mandibular hypoplasia 8 years after radiotherapy. Significant volume decrease was achievable within a few years after radiotherapy in benign soft tissue tumors. Therefore, radiotherapy is a viable option for unresectable or incompletely resected benign soft tissue tumors with a minimum risk of complication.
