Clinics in Orthopedic Surgery 2025;17(2):300-307
Background:
The rarity and complexity of trans-ulnar basal coronoid fracture-dislocations pose significant challenges in treatment. This study aimed to categorize these fractures based on coronoid fracture patterns and propose tailored surgical approaches for each type. Additionally, we evaluated the functional and radiological outcomes among the patients managed using our treatment algorithm.
Methods:
A total of 19 patients who underwent open reduction and internal fixation for trans-ulnar basal coronoid fracture-dislocations between March 2018 and October 2022 were enrolled in this study. These patients were classified based on the coronoid fracture patterns associated with olecranon fractures: type 1 involved anteromedial facet (AMF) fractures, type 2 encompassed coronoid base and body fractures, and type 3 involved a combination of types 1 and 2. We made a midline longitudinal dorsal incision to facilitate the provisional fixation of the olecranon fragment to the distal metaphysis using a locking plate. Subsequently, we employed the over-the-top (type 1) and Taylor–Scham (type 3) approaches for direct coronoid process fixation with buttress plating.Type 2 fractures were approached via medial fascial exposure from the posterior ulnar cortex or through the olecranon fractures, and subsequently fixed with miniplates and screws. Bony union and joint articulation were assessed via plain radiographs, and functional outcomes were evaluated using range of motion and the Mayo Elbow Performance Score.
Results:
Among the 19 patients, 3 had type 1 fractures, 14 had type 2 fractures, and 2 had type 3 fractures. All fractures exhibited solid osseous union without subluxation or dislocation. The average flexion and extension arc was 119.47° ± 20.88°, with a mean flexion of 127.37° ± 13.37° and an average flexion contracture of 7.89° ± 10.04°. The average Mayo Elbow Performance Score was 82.63 ± 12.51 points. Qualitatively, patient outcomes were excellent in 5 patients, good in 9, and fair in 5.
Conclusions
Most of our patients presented with easily approachable coronoid base and body fractures. However, in AMF fractures of the coronoid process, a direct medial approach is required for buttress plating. We believe our study helps provide useful guidelines for making appropriate decisions in trans-ulnar basal coronoid fracture-dislocations .

Purpose:
This study aimed to examine the effects of gonadotropin-releasing hormone agonist (GnRHa) treatment on final height outcomes in girls with idiopathic central precocious puberty (CPP) from the start of treatment to their postmenarche visit.
Methods:
We conducted a retrospective analysis of 200 girls with idiopathic CPP who received GnRHa therapy, focusing on auxological and clinical outcomes at treatment initiation, treatment completion, and the last, postmenarche visit.
Results:
The mean chronological age (CA) at GnRHa treatment initiation was 8.24±0.73 years. The mean duration of GnRHa treatment was 3.12±0.81 years. The average age at menarche was 12.73±0.56 years, occurring a mean of 17.15±5.52 months after completing GnRHa therapy. The predicted adult height (PAH) standard deviation score (SDS) after menarche (0.48±0.99) was significantly greater than before treatment (-1.33±1.46) (P<0.001). Factors including greater bone age advancement (P<0.001), lower height SDS for CA at treatment initiation (P<0.001), and higher midparental height SDS (P=0.001) were positively associated with an increase in PAH SDS at the last visit. However, near-final height and the increase in PAH SDS at the last visit were not significantly different between patients who received early treatment (<8 years) and those who received later treatment (8–9 years).
Conclusion
GnRHa treatment improved the final height outcomes in all girls with CPP, including those treated between 8 and 9 years of age.

Journal of the Korean Society of Biological Psychiatry 2024;31(2):40-50
Objectives:
We investigate relationship between suicide attempts and peripheral blood inflammatory markers in patients visiting the emergency department (ED) for psychiatric consultations, aiming to identify potential biomarkers for predicting suicide risk.
Methods:
We retrospectively reviewed medical records of 569 patients who were referred to psychiatric consultation at the ED from January 1, 2022 to December 31, 2022. Demographic and clinical characteristics and various blood test markers were analyzed. Analyses were performed to compare differences in blood markers between suicide attempters and non-attempters and among those with varying histories of suicide attempts.
Results:
Among 569 patients, 398 (69.9%) had attempted suicide. Significant differences in leukocytes, lymphocytes, eosinophils, red blood cells (RBCs), lactate dehydrogenase (LDH), and ketone bodies were observed between suicide attempters and non-attempters. Further analysis revealed that patients with a history of suicide attempts had higher lymphocyte and eosinophil counts but lower LDH and ketone body levels. An increasing frequency of past suicide attempts correlated with higher lymphocyte and eosinophil count and lower neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, platelet-to-lymphocyte ratio, systemic immune inflammatory index, glucose, LDH, and ketone body levels.
Conclusions
We identify blood markers associated with suicide attempts, indicating that leukocyte, lymphocyte, eosinophil, RBC count, LDH, and ketone body levels could serve as potential biomarkers for assessing suicide risk. Findings underscore importance of biological assessments in conjunction with psychological evaluations in predicting and preventing suicide attempts. Further research is needed to validate these biomarkers and understand mechanisms.

Primary aldosteronism is a group of disorders in which the autonomous secretion of aldosterone is associated with hypertension and hypokalemia. It is crucial to determine the laterality of aldosterone hypersecretion because treatment options differ accordingly. Adrenal venous sampling (AVS) is considered the most reliable method for assessing the laterality of primary aldosteronism. This procedure is often technically challenging because of the small size and varied locations of the adrenal veins. A better understanding of anatomical variations and careful review of imaging studies would improve sampling success. This report presents three cases of anatomical variations encountered during AVS.
