The purpose of this study was to determine whether head posture affects three-dimensional (3D) facial images. This study evaluated facial images of 10 mannequins, which are taken from standard postures, left and right rotations, and up and down rotations. The images with changed head posture were superimposed onto standard head posture image, and the difference between the two images was used to evaluate deformations in images with the changed head postures. The 3D facial images showed considerable differences depending on different head positions.

Objectives:
This study aimed to compare the demographic characteristics, responses to negative emotions, and difficulties in emotion regulation between self-harming adolescents and control individuals aged 12–14 years from the community.
Methods:
Data were collected from adolescents in Chungcheong Province, South Korea, between September 2021 and November 2022.Demographic characteristics and responses to the Depressed Mood Questionnaire and Difficulties in Emotion Regulation Scale-16 (DERS-16) were compared between the self-harm and control groups.
Results:
The self-harm group exhibited a higher prevalence of child abuse (odds ratio [OR]=4.787, 95% confidence interval [CI]=1.591– 14.409, p=0.005) and school bullying victimization (OR=4.495, 95% CI=2.353–8.588, p<0.001) than those in the control group. The selfharm group displayed higher levels of rumination (t=7.88, p<0.001) and reduced distraction responses (reverse score t=2.25, p=0.025) than those of the control group. Additionally, the self-harm group scored higher on all subscales and the total DERS-16 score (t=7.61, p<0.001).
Conclusion
Interventions for self-harming adolescents should address child abuse and bullying victimization. Prevention programs for self-harming adolescents should focus on reducing rumination responses, increasing distractive responses, and addressing difficulties in emotion regulation using dialectical behavior therapy-skill training.

BACKGROUND: Automated blood cell analyzers often read leukemic blasts as normal cells. In this study, we evaluated the 5-part differential patterns of blasts using automated analyzers to determine if they can differentiate among blast types. METHODS: Blood samples containing 10% or more blasts were collected from patients with acute leukemia (N=175). The 5-part differential count was conducted using DxH 800 (Beckman Coulter, USA) and XE-2100 analyzers (Sysmex Co., Japan), and the results were compared with manual differential counts, which was used as a reference method. RESULTS: The DxH 800 reported the 5-part white blood cell differential count in 98.9% of the cases. The XE-2100 provided an invalid automated differential count in 72% of the cases. Both analyzers counted most lymphoblasts as lymphocytes and most myeloblasts as monocytes. In 11 cases, the DxH 800 reported a 5-part differential count without a blast flag. CONCLUSIONS: Some automated analyzers are able to recognize and count blasts according to their characteristic cell types. Therefore, complete blood counts obtained automatically can provide valuable data for making provisional decisions regarding the lineage of leukemia cells before further investigation.

Co-administration of tadalafil and tamsulosin HCl in patients with benign prostate hyperplasia and erectile dysfunction is increasing in clinical settings. Development of fixed-dose combination (FDC) of tadalafil and tamsulosin HCl could contribute to improving patients' adherence and treatment efficacy. We evaluated the pharmacokinetics and safety profiles of a newly developed fixed-dose combination capsule of tadalafil 5 mg/tamsulosin HCl 0.4 mg in comparison with co-administration of each formulation in healthy volunteers under fasted and fed conditions. Two randomized, open-label, single-dose, two-way, crossover studies were completed in 29 subjects under fasted condition, and 33 subjects under fed condition. Serial blood sample collection for PK analysis was conducted up to 72 hours after dosing, and PK parameters were calculated using non-compartmental analysis. Geometric mean ratios and 90% confidence intervals of the C(max) and AUC(last) were used to evaluate comparative bioavailability. In both fasted and fed condition studies, the bioequivalence was established. The most common adverse drug reactions were orthostatic hypotension and headache with no statistical difference between treatment groups. All subjects with orthostatic hypotension recovered at follow-up test. Although changes in vital signs from baseline were statistically significant, there were no subjects with systolic blood pressure < 90 mmHg and there were no clinically meaningful signs or symptoms associated. FDC of tadalafil and tamsulosin HCl can be an alternative to co-administration of individual drugs for providing better compliance. Changes in blood pressure should be kept in mind when tadalafil and tamsulosin HCl are co-administered in clinical settings.
