Background:
The objective of this study was to investigate sequential changes in range of motion (ROM) and histopathology of the joint capsule after remobilization in a rat adhesive capsulitis (AC) model using cast immobilization.
Methods:
Thirty-five 6-week-old Sprague-Dawley rats were immobilized with casting of the left shoulder. After 4 weeks, the rats were randomly divided into 7 groups (n = 5 per group) according to the duration of remobilization following cast removal: 0 (D0), 1 (W1), 2 (W2), 3 (W3), 4 (W4), 5 (W5), and 6 (W6) weeks. At each time point, 5 rats were euthanized for measurement of the glenohumeral abduction angle and evaluation of capsular thickness in the axillary recess.
Results:
Abduction angle was sequentially increased at each time point after remobilization with cast removal. Significant differences between immobilized and non-immobilized shoulders were observed at D0 (130.4° vs 161.3°), W1 (144.7° vs 160.7°), and W2 (142.3° vs 161.3°). Significant differences in capsular thickness of the axillary recess were observed between immobilized and non-immobilized shoulders at all time periods including D0 (98.0 μm vs. 12.9 μm), W1 (117.7 μm vs. 12.2 μm), W2 (115.7 μm vs.13.1 μm), W3 (54.1 μm vs. 14.9 μm), W4 (54.5 μm vs. 13.4 μm), W5 (23.8 μm vs. 13.5 μm), and W6 (19.8 μm vs. 12.4 μm). Significant differences in capsular fibrosis scores were observed between immobilized and non-immobilized shoulders at W1 (2.2 vs. 0.2) and W2 (2.2 vs. 0.0).
Conclusions
Our study showed that ROM increased sequentially after remobilization in a rat AC model using cast immobilization, and it was normalized at 6 weeks after cast removal. Capsular thickening decreased sequentially, but remained at 6 weeks after cast removal. These findings may provide useful information for further research into verifying potential therapeutic targets using a rat AC model with cast immobilization.

Postmortem inspection is a specialized medical practice that determines the cause and manner of death via external examination of a corpse. It is performed as part of the medico-legal death investigation and a crucial step in determining whether an autopsy is necessary. In South Korea, training for doctors performing postmortem inspection and quality control for postmortem inspection results remain lacking. Therefore, the Korean Society for Legal Medicine established a task force and proposed a standard operating procedure (SOP) of postmortem inspection. This article includes the background for proposing this SOP, an introduction to the postmortem inspection process, and the principles for performing the procedure and writing the report. This SOP may serve as a basic guideline for postmortem inspection.

Infectious disease constitutes on one of the main causes of death that is identified on forensic autopsies. However, the postmortem diagnosis of these diseases and the assessment of their severity constitute major challenges. Procalcitonin (PCT), which is used as a biomarker for sepsis in clinical settings, has been applied in the context of forensic autopsies. In this study, we aimed to evaluate the utility of PCT testing in the postmortem diagnosis of infectious disease. This retrospective analysis included cases wherein autopsies with PCT testing were performed at the National Forensic Service between November 2023 and December 2024. Relevant data were collected through a comprehensive review of autopsy reports. Although the PCT concentrations in the infectious disease group were significantly higher than those in the control group, clinical sepsis criteria showed limited sensitivity in the postmortem diagnosis of infectious diseases. The comparison of clinical medical records and postmortem laboratory results revealed that PCT concentrations decreased after death. Thus, despite the usefulness of PCT testing for the postmortem diagnosis and determination of death from infectious diseases, the results should be interpreted comprehensively in conjunction with other autopsy findings rather than being used as a standalone criterion.

Journal of the Korean Medical Association 2026;69(3):268-280
Purpose:
To develop the 2025 update to the Korean colorectal cancer (CRC) screening guidelines by systematically evaluating recent evidence, integrating domestic data, and addressing changes since the 2015 guideline revision, thereby providing an evidence-based standard for clinicians and policymakers.
Methods:
A multidisciplinary committee developed the guidelines using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology. The process included formulation of three key questions addressing screening efficacy, diagnostic accuracy, and optimal screening age and interval. A systematic review of international guidelines and primary literature was conducted, yielding 327 eligible studies. In addition, a utility-based analysis using a Markov model was performed to determine optimal screening ages and intervals.
Results:
The evidence synthesis identified high-certainty evidence supporting the use of the fecal immunochemical test (FIT) for reducing CRC mortality and moderate-certainty evidence for colonoscopy. Evidence for computed tomographic colonography (CTC) and stool DNA testing was rated as very low certainty. Based on the evidence review and cost-utility analysis, the committee conditionally recommends CRC screening for asymptomatic, average-risk adults aged 45–74 years using either colonoscopy every 10 years or FIT every 1–2 years. CTC and stool DNA testing were not recommended owing to insufficient evidence.
Conclusion
The 2025 Korean Guidelines for Colorectal Cancer Screening present updated, evidence-based recommendations tailored to the domestic healthcare context. By conditionally endorsing both colonoscopy and FIT for individuals aged 45–74 years, these guidelines aim to improve population-level screening effectiveness and reduce the burden of CRC in South Korea.

Objective:
The objective of this study was to establish reference ranges related to the feet of normal Jeju horses by measuring the angles and length of the hoof, and the Hounsfield Unit (HU) value of soft tissues in the foot.
Methods:
Sixteen normal Jeju horses (mean age: 4.25 years; mean body weight: 282.06 kg) without lameness were examined using CT. After CT scanning, the angles and lengths of the hoof, such as hoof width and dorsal hoof wall angle, and the HU values of the soft tissues, such as the deep digital flexor tendon, were measured.
Results:
We identified significant differences in the HU values of overall soft tissues between the forelimbs and hindlimbs, and between the medial and lateral parts (p < 0.05). Length measurements showed no differences between left and right limbs or between medial and lateral parts, but significant fore–hind differences were found in most parameters (p < 0.05).Angle measurements revealed significant differences between left and right limbs and between fore- and hindlimbs, with an additional medial–lateral difference in the left hindlimb (p < 0.05).
Conclusions
and Relevance: The CT-based reference values established in this study provide valuable breed-specific data that may support assessment of hoof conformation and interpretation of CT findings in Jeju horses.

Objective:
This study assessed the behavioral and cardiorespiratory effects of medetomidine (M) administered with and without tramadol (T) in horses.
Methods:
Eight horses were sedated intravenously with M (5 µg/kg) alone or with T (2 mg/ kg) in a arandomized, blind, two-way crossover trial. Behavioral responses, including head height above the ground (HHAG), postural instability (PI), and response to pressure stimulus (RPS), and cardiorespiratory responses, including vital variables and blood analyses, were assessed following administration.
Results:
There were no clinically meaningful differences in cardiorespiratory values, HHAG, or PI between the groups. The RPS score over the scapula was significantly higher in the medetomidine and tramadol (MT) group (p < 0.05) and a trend towards a higher RPS score over the femur was observed (p = 0.08) in the MT group. Heart rate decreased significantly below baseline from 10 to 40 min in both treatments.
Conclusions
and Relevance: These results suggest that the MT combination may provide sufficient sedation and analgesia with minimal cardiorespiratory changes in horses.

OBJECTIVES:
Kudoa septempunctata has been identified as the causative agent of food poisoning following the consumption of raw farmed Paralichthys olivaceus. However, cohort studies providing robust evidence for an association between K. septempunctata and gastrointestinal symptoms remain limited. This prospective cohort study investigated the association between the consumption of K. septempunctata–infected farmed P. olivaceus and the occurrence of gastrointestinal symptoms.
METHODS:
Individuals who purchased raw farmed P. olivaceus between 2020 and 2021 were selected as the study population. Study data included 2 rounds of questionnaire surveys administered before and after consumption, 2 muscle specimens obtained from each purchased fish, and human biological specimens collected from individuals who developed gastrointestinal symptoms within 24 hours after consumption. Data were analyzed using the chi-square test and t-test, and the association between consumption of K. septempunctata–infected farmed P. olivaceus and gastrointestinal symptoms was evaluated using relative risk estimates between exposure groups.
RESULTS:
The relative risk of gastrointestinal symptoms associated with exposure to K. septempunctata–infected P. olivaceus ranged from 71.2 (95% confidence interval [CI], 27.0 to 178.6) to 124.5 (95% CI, 43.5 to 355.0) across the 2 case definitions. A strong and statistically significant association was observed between exposure to K. septempunctata–infected P. olivaceus and the development of acute gastrointestinal symptoms.
CONCLUSIONS
These findings indicate both an association and a causal relationship between consumption of K. septempunctata–infected farmed P. olivaceus and the onset of gastrointestinal symptoms.

Tuberculosis (TB) remains a significant global health issue, with undiagnosed cases posing risks to public health and forensic personnel. Forensic autopsies are important in identifying TB cases, as undetected infections in deceased individuals can lead to occupational exposure through aerosolized transmission. However, TB surveillance in forensic autopsies remains insufficient, limiting its recognition in public health strategies. This study analyzed 43,190 forensic autopsies conducted in South Korea from 2019-2023, identifying 195 TB cases (0.45%), including 114 deaths (0.26%) primarily caused by TB. The highest prevalence was recorded in 2019 (0.59%), with a gradual decline in subsequent years. Regional analysis showed that Incheon had the highest TB prevalence (0.74%). Pulmonary TB was the most common (80.77%), followed by miliary TB (15.38%). These findings highlight the potential occupational risks for forensic personnel because of undiagnosed TB infections. Notably, 72.3% of TB cases were identified postmortem without previous medical records, increasing the likelihood of unprotected exposure. Additionally, forensic investigations often lack systematic reporting of TB cases, making it difficult to assess the true prevalence and risks. Strengthening TB monitoring in forensic autopsies can enhance case identification and improve public health surveillance. Establishing a more structured reporting system for TB cases in forensic settings may help prevent occupational exposure and support national TB control efforts.

Journal of Clinical Neurology 2025;21(3):220-229
Background:
and Purpose The pain lateralization in cluster headache (CH) may be related to the asymmetry in the functions of the brain hemispheres. The right-sided dominance of pain in CH has been found inconsistently across studies, and so we aimed to characterize this and identify the factors influencing pain lateralization during current and previous bouts.
Methods:
This study enrolled 227 patients from the Korean Cluster Headache Registry between October 2018 and December 2020. We evaluated the side of pain during current and previous bouts, demographic features, and clinical characteristics, including handedness. Multivariable logistic regression analyses were performed to identify factors associated with the side of pain.
Results:
The 227 patients with CH included 131 (57.7%) with right-sided pain and 86 (37.9%) with left-sided pain during the current bout (p<0.001). The 189 patients with previous bouts of CH included 86.8% who consistently reported the same side of pain throughout multiple bouts (side-locked pain), with a higher prevalence of pain on the right than the left side (55.0% vs. 31.7%, p<0.001). Multivariable analyses revealed that higher age at diagnosis (odds ratio [OR]=1.045, p=0.031) and shorter CH attacks (OR=0.992, p=0.017) were associated with left-side-locked pain. However, handedness was not associated with the lateralization of leftside-locked pain.
Conclusions
This study has confirmed the predominance of right-sided pain throughout multiple CH bouts. We found that higher age at diagnosis and shorter CH attacks were associated with left-side-locked pain, suggesting that certain clinical factors are associated with the pain laterality. However, the underlying mechanisms linking these factors to lateralized pain remain unclear and therefore require further investigation.
