Background:
s/Aims: The treatment landscape for hepatocellular carcinoma (HCC) has significantly evolved over the past decade. We aimed to analyze trends in treatment patterns for HCC using a nationwide claims database from the Korean Health Insurance Review and Assessment Service.
Methods:
This retrospective population-based cohort study analyzed 171,002 newly diagnosed HCC patients between 2008 and 2022. Etiologies and treatment modalities were categorized based on the ICD-10 codes and insurance data.
Results:
The annual incidence decreased from 11,814 in 2008 to 10,443 in 2022. However, patients aged ≥70 increased noticeably, with those aged ≥80 rising from 3.8% in 2008 to 13.1% in 2022. From 2008 to 2022, the predominant cause of hepatitis B virus decreased from 68.9% to 59.7%, whereas nonalcoholic fatty liver disease increased from 8.9% to 15.8%. The initial treatment trends shifted: surgical resection and systemic therapy increased from 12.2% to 21.3% and from 0.2% to 9.6%, whereas transarterial therapy decreased from 49.9% to 36.6%. Best supportive care decreased from 31.7% to 21.3%. In the subgroup analysis, laparoscopic resection rate increased from 10.6% to 60.6% among the surgical resections. Sorafenib initially accounted for 100%, lenvatinib peaked at 36.5% in 2021, and atezolizumab-bevacizumab became the most widely used (63.1%) by 2022 among the systemic therapies.
Conclusions
This study demonstrates the temporal changes in the treatment patterns of Korean HCC patients. Surgical resection, particularly laparoscopic liver resection, and systemic therapy has increased significantly. These changes may have been influenced by reimbursement policies and advances in clinical research.

Physician–scientists play a pivotal role in bridging clinical practice and biomedical research, advancing medical science, and tackling complex healthcare challenges. In South Korea, the declining number of medical doctors engaging in basic medical sciences has prompted the implementation of various training initiatives since the 2000s. Notable initiatives, such as the Integrated Physician–Scientist Training Program (2019) and the Global Physician–Scientist Training Program (2024), aim to cultivate multidisciplinary physician–scientists capable of addressing unmet medical needs. This study offers a comprehensive overview of the current training systems, funding mechanisms, and strategic approaches for physician–scientists in South Korea, compares them with international best practices, and proposes actionable policy recommendations to enhance their effectiveness and long-term sustainability.

Mycoplasma pneumoniae is a common cause of respiratory tract infections and typically causes mild disease. Extrapulmonary manifestations of M. pneumoniae infection are also common, but rhabdomyolysis is a rare complication. Here, we describe the case of a previously healthy 23-year-old male who displayed the simultaneous onset of rhabdomyolysis and severe pneumonia requiring mechanical ventilation. Both conditions were resolved by a 10-day course of antimicrobial treatment and the patient was discharged without complication.

BACKGROUND: Leprosy is an infectious disease with two polar forms, tuberculoid leprosy (TT) and lepromatous leprosy (LL), that are characterized by strong cell-mediated immunity (CMI) and CMI anergy, respectively. Transforming growth factor-beta (TGF-beta) is a family of growth factors involved in essential physiological processes, including development, differentiation, tissue repair, cell growth control and inflammation. Cellular signaling by TGF-beta family members is initiated by the assembly of specific cell surface receptors that activate transcription factors of the Smad family. Deregulation of the TGF-beta-Smad signaling pathway has been implicated in developmental disorders and several human diseases. Recently, ELISA & immunohistochemistry revealed high expression of TGF-beta isoforms in LL. OBJECTIVE: The purpose of this study was to investigate TGF-beta-Smad signaling in various forms of leprosy. METHODS: We investigated the involvement of TGF-beta by immunohistochemical staining for Smad 2 and 3 in skin biopsies from six patients of BL and four patients of TT. RESULTS: The inflammatory cells, keratinocytes and fibroblasts in BL showed strong positivity for both Smad 2 and 3, whereas those in TT showed little positivity. CONCLUSION: The high expression of Smad 2/3 in BL could represent high expression of TGF-beta, which possibly contributes to local CMI anergy and other clinical characteristic features of leprosy.

Adrenal insufficiency during the treatment of pulmonary tuberculosis is a troublesome condition and can at times be lifethreatening if untreated. Rifampin is one of the most widely prescribed anti-tuberculosis agents. Furthermore, rifampin has been known to be capable of affecting the metabolism of various medications, including glucocorticoids. In this paper, a case of recurrent adrenal insufficiency induced by rifampin during the treatment of pulmonary tuberculosis is reported. The patient was a 63-year-old man who was diagnosed with Addison's disease 17 years earlier and had been undergoing glucocorticoid replacement therapy. Five months before, the patient manifested pulmonary tuberculosis and was immediately given anti-tuberculosis medication that included rifampin. After one week of medication, general weakness and hyponatremia occurred. Despite the increased dose of the glucocorticoid medication, the adrenal insufficiency recurred many times. Since the substitution of levofloxacin for rifampin, the episodes of adrenal insufficiency have not recurred so far.

Gastric cancer is one of the leading causes of cancer-related deaths worldwide. Because the gastric cancer-related mortality rate is expected to increase, chemo-preventive strategies for gastric cancer are required. Statins inhibit 3-hydroxy-3-methylglutaryl coenzyme A reductase, the enzyme involved in the rate-limiting step in cholesterol synthesis. Several studies have shown that statins have potential protective effects against gastric cancer; however, other studies have reported contradictory results. Therefore, further studies are needed to clarify the role of statins in the chemoprevention of gastric cancer.

Dermatomyositis is a rare disease of unknown origin that combines an inflammatory myopathy with characteristic cutaneous findings. Scalp disease has rarely been considered as a manifestation of dermatomyositis and is often misdiagnosed as being scalp paosiasis or seborrheic dermatitis. We report a case of 27-year-old woman who presented with brownish alopecic patches on the scalp, and chronic proximal muscle weakness.
