Brainstem infarction can be a critical condition, typically due to ischemic mechanisms such as large artery atherosclerosis, small vessel disease, or cardioembolic sources. In rare instances, infectious or inflammatory etiologies may lead to brainstem infarction, posing substantial diagnostic complexities. We report the case of a 74-year-old man presenting bilateral pontine infarctions secondary to clival osteomyelitis and an adjacent abscess, which was further complicated by a basilar artery pseudoaneurysm and subsequent subarachnoid hemorrhage. This case highlights the importance of considering uncommon infectious causes of brainstem infarction, especially in patients with intricate medical backgrounds and immunosuppression.

Background:
Coronary artery calcification and carotid plaque are recognized indicators of atherosclerosis, both linked to elevated cardiovascular and cerebrovascular risks. This study investigates the association between coronary artery calcification and carotid plaque and examines key risk factors associated with carotid plaque presence.
Methods:
We enrolled 2,620 participants who underwent coronary artery calcium scoring via computed tomography and carotid ultrasound for health check-up from January 2017 to December 2022. Patient data, including age, sex, hypertension, diabetes mellitus, dyslipidemia, smoking history, body mass index, glucose, cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and lipoprotein(a), were collected. Logistic regression analyses were performed to explore the relationship between coronary artery calcification and carotid plaque, adjusting for major cerebrovascular risk factors.
Results:
Coronary artery calcification was present in 44.7% of participants, and carotid plaque was detected in 43.5%. Univariable analysis showed a significant association between coronary artery calcification and carotid plaque (unadjusted odds ratio: 4.393, p<0.001). In the multivariable model, which included age, sex, hypertension, dyslipidemia, glucose, low-density lipoprotein cholesterol, and coronary artery calcification presence, coronary artery calcification remained an independent predictor of carotid plaque (adjusted odds ratio: 2.327, p<0.001). The model’s area under the receiver operating characteristic curve was 0.768.
Conclusion
Our study demonstrates that coronary artery calcification is independently and significantly associated with carotid plaque in a health check-up population. Carotid imaging, such as carotid ultrasound, may be beneficial for early detection and management of carotid atherosclerosis in patients with coronary artery calcification.

Journal of Neurosonology and Neuroimaging 2024;16(1):1-7
Background:
Carotid plaque formation is a major global health issue and contributes in pathogenesis of vascular diseases. Lipoprotein(a), similar to low-density lipoprotein, may influence atherogenesis by promoting inflammation and thrombosis. However, the association between lipoprotein(a) levels and presence of carotid plaques has been debated. This study investigated the correlation between these parameters.
Methods:
We retrospectively analyzed 4,896 individuals who underwent lipoprotein(a) measurement and carotid ultrasonography at Gangnam Severance Hospital between January 2017 and December 2022. The relationship between lipoprotein(a) levels and the presence of carotid plaques was evaluated using logistic regression analysis adjusted for factors such as age, sex, hypertension (HTN), dyslipidemia, and diabetes mellitus (DM).
Results:
Among the 4,896 enrolled participants, those with carotid plaques were older, more likely to be men, and had a higher prevalence of HTN, DM, and dyslipidemia. The analysis showed a significant association between the presence of carotid plaques and a level of lipoprotein(a) ≥50 mg/dL in both univariable (unadjusted odds ratio=1.508, p<0.001, 95% confidence interval: 1.192–1.907) and multivariable (adjusted odds ratio=1.335, p=0.029, 95% confidence interval: 1.030–1.731) models.
Conclusion
Elevated lipoprotein(a) level emerged as an independent risk factor for carotid plaque formation, emphasizing the need for integrated risk assessment. Targeting lipoprotein(a) could enhance preventive strategies against cerebrovascular events. Therefore, further research is warranted to elucidate this disease’s underlying mechanisms and evaluate therapeutic interventions.

Uncontrolled inflammation is considered the pathophysiological basis of many prevalent metabolic disorders, such as nonalcoholic fatty liver disease, diabetes, obesity, and neurodegenerative diseases. The inflammatory response is a self-limiting process that produces a superfamily of chemical mediators, called specialized proresolving mediators (SPMs). SPMs include the ω-3-derived family of molecules, such as resolvins, protectins, and maresins, as well as arachidonic acid-derived (ω-6) lipoxins that stimulate and promote resolution of inflammation, clearance of microbes, and alleviation of pain and promote tissue regeneration via novel mechanisms. SPMs function by binding and activating G protein-coupled receptors, such as FPR2/ALX, GPR32, and ERV1, and nuclear orphan receptors, such as RORα. Recently, several studies reported that SPMs have the potential to attenuate lipid metabolism disorders. However, the understanding of pharmacological aspects of SPMs, including tissue-specific biosynthesis, and specific SPM receptors and signaling pathways, is currently limited. Here, we summarize recent advances in the role of SPMs in resolution of inflammatory diseases with metabolic disorders, such as nonalcoholic fatty liver disease and obesity, obtained from preclinical animal studies. In addition, the known SPM receptors and their intracellular signaling are reviewed as targets of resolution of inflammation, and the currently available information on the therapeutic effects of major SPMs for metabolic disorders is summarized.

Journal of Korean Medical Science 2021;36(46):e322-
Background:
This study aimed to evaluate traumatic stress and mental health problems associated with the prolonged coronavirus disease pandemic and to determine the differences across different age groups.
Methods:
A total of 1,151 individuals who visited Gwangmyeong City Mental Health Welfare Center, South Korea, or accessed the website from September 1 to December 31, 2020, were included in the study. Mental health problems such as traumatic stress (Primary Care Posttraumatic Stress Disorder Screen for the Diagnostic and Statistical Manual of Mental Disorder-5); depression (Patient Health Questionnaire-9 and Children's Depression Inventory); anxiety (Generalized Anxiety Disorder-7 and Penn State Worry Questionnaire for Children); suicide risk (P4 Screener); and demographic information were evaluated. The participants were divided into three groups based on age group: children and adolescents, adults, and the elderly.
Results:
The results showed that 24.7%, 20.9%, 16.8%, and 20.5% of the participants were at high-risk for traumatic stress, depression, anxiety, and suicide, respectively. The difference in the proportion of high-risk groups by age of all participants was significant for traumatic stress, depression, anxiety, and suicide risk. In particular, the percentage of high-risk groups in all areas was the highest in the adult group. Also, in most areas, the ratio of the high-risk groups for children and adolescent group was the lowest, but the suicide risk-related ratio was not (adolescent group: 20.9%, adult group: 25%, elderly group 9.3%).
Conclusion
These results suggest that there is a need for continued interest in the mental health of the general population even after the initial period of coronavirus disease.Additionally, this study may be helpful when considering the resilience or risk factors of mental health in a prolonged disaster situation.

Adiponectin secretion-promoting compounds have therapeutic potentials in human metabolic diseases. Diallyl biphenyl-type neolignan compounds, magnolol, honokiol, and 4-O-methylhonokiol, from a Magnolia officinalis extract were screened as adiponectin-secretion promoting compounds in the adipogenic differentiation model of human bone marrow mesenchymal stem cells (hBM-MSCs). In a target identification study, magnolol, honokiol, and 4-O-methylhonokiol were elucidated as PPARα and PPARγ dual modulators. Diallyl biphenyl-type neolignans affected the transcription of lipid metabolism-associated genes in a different way compared to those of specific PPAR ligands. The diallyl biphenyl-type neolignan structure provides a novel pharmacophore of PPARα/γ dual modulators, which may have unique therapeutic potentials in diverse metabolic diseases.

PURPOSE: Periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome is a leading cause of periodic fever in children. This study describes the clinical characteristics of PFAPA syndrome in patients from a single center.METHODS: Thirteen children diagnosed with PFAPA syndrome at Seoul National University Children's Hospital were included in this study. Retrospective medical chart reviews were performed.RESULTS: Among the 13 patients, 8 (61.5%) were male. The median follow-up duration was 3.3 years (range, 10 months–8.3 years). The median age of periodic fever onset was 3 years (range, 1–6 years). All patients had at least 5 episodes of periodic fever and pharyngitis, managed with oral antibiotics, before diagnosis. The median occurrence of fever was every 3.9 weeks and lasted for 4.2 days. All patients had pharyngitis and 12 (92.3%) had cervical lymphadenitis. Blood tests were performed for 12 patients, and no patients had neutropenia. Both the C-reactive protein and erythrocyte sedimentation rate were elevated at medians of 4.5 mg/dL (range, 0.4–13.2 mg/dL) and 29 mm/hr (range, 16–49 mm/hr), respectively. Throat swab cultures and rapid streptococcal antigen tests were negative. Nine (69.2%) patients received oral prednisolone at a median dose of 0.8 mg/kg, and in 6 (66.7%) patients, fever resolved within a few hours. Three (23.1%) patients received tonsillectomy and adenoidectomy.CONCLUSIONS: PFAPA syndrome should be considered when a child presents with periodic fever along with aphthous stomatitis, pharyngitis, or cervical lymphadenitis. Glucocorticoid administration is effective for fever resolution and can reduce unnecessary use of antibiotics.

PURPOSE: Hypothermia at admission is associated with increased mortality and morbidity in preterm infants. We performed a quality improvement (QI) effort to determine the impact of a decrease in admission hypothermia in preterm infants. METHODS: The study enrolled very low birth weight (VLBW) infants born at Gangnam Severance Hospital between January 2013 and December 2016. This multidisciplinary QI effort included the use of occlusive wraps, warm blankets, and caps; the delivery room temperature was maintained above 23.0℃, and a check-list was used for feedback. RESULTS: Among 259 preterm infants, the incidence of hypothermia (defined as body temperature <36.0℃) decreased significantly from 68% to 41%, and the mean body temperature on neonatal intensive care unit admission increased significantly from 35.5℃ to 36.0℃. In subgroup analysis of VLBW infants, admission hypothermia and neonatal outcomes were compared between the pre-QI (n=55) and post-QI groups (n=75). Body temperature on admission increased significantly from 35.4℃ to 35.9℃ and the number of infants with hypothermia decreased significantly from 71% to 45%. There were no cases of neonatal hyperthermia. The incidence of pulmonary hemorrhage was significantly decreased (P=0.017). Interaction analysis showed that birth weight and gestational age were not correlated with hypothermia following implementation of the protocol. CONCLUSION: Our study demonstrated a significant reduction in admission hypothermia following the introduction of a standardized protocol in our QI effort. This resulted in an effective reduction in the incidence of massive pulmonary hemorrhage.

Since IgG4-related pancreatitis was first reported in 2001, IgG4-related disease has been identified in other organs such as salivary gland, gallbladder, thyroid, retroperitoneum and kidney; but lung invasion is rare. A 63-year-old man presented with hemoptysis at the pulmonary clinic and chest computed tomography revealed about 4.1 cm irregular shaped mass with spiculated margin at the left upper lobe. Despite no elevation of serum IgG4 level, he was finally diagnosed as IgG4-related lung disease by transthoracic needle biopsy. After treatment with oral glucocorticoids, hemoptysis disappeared and the size of lung mass was decreased.
