Purpose:
To evaluate the compatibility and usability of test results obtained from the IDRA and Keratograph 5M in clinical settings by comparing their performance in patients with dry eye disease.
Methods:
From December 27 to 30, 2022, a study was conducted on 30 patients diagnosed with dry eye utilizing both the Keratograph 5M and IDRA devices. The parameters compared and analyzed included lipid layer thickness, tear meniscus height, tear film break-up time, and meibography. A paired t-test was used for statistical comparison. The lipid layer thickness in the Keratograph 5M was graded on a scale from 0 to 4 based on thickness.
Results:
No significant differences were found between the two devices in tear film break-up time, tear meniscus height, and meibography (p = 0.148, 0.072, 0.124, respectively). However, the tear lipid layer thickness measured by IDRA showed a proportional relationship with the grade assigned by the Keratograph 5M (Kendall R = 0.217, p = 0.037; Spearman R = 0.260, p = 0.045).
Conclusions
The IDRA device offers the advantage of performing multiple dry eye tests; simultaneously, thereby saving time compared to the Keratograph 5M. Both devices can be used compatibly with IDRA particularly advantageous for providing a numerical value for tear lipid layer thickness which enhances the convenience of dry eye diagnosis and treatment.

Journal of Korean Academy of Oral Health 2024;48(4):186-191
Objectives:
This study aimed to investigate the current status of periodontal disease programs implemented by public health centers in the Republic of Korea.
Methods:
An explanatory survey was conducted by the Ministry of Health and Welfare from October to November 2023. The survey focused on the periodontal programs and the implementation status across different stages. Distributed and collected via Google Forms, the survey targeted 196 oral health teams within public health centers in Korea. A total of 109 public health centers responded to the study questionnaire, yielding a participation rate of 55.6%. Data were analyzed using IBM SPSS Statistics for Windows, version 26.
Results:
A majority of periodontal disease programs were implemented exclusively by oral health teams, with a rate of 33.0%. The implementation rate of collaboration with home-visiting health teams was 17.4% and with other teams was 10.1%. The implementation rates of periodontal management across stages were as follows: 11.9% for periodontal examination, 18.3% for periodontal treatment, and 11.9% for sustainable periodontal care.
Conclusions
Periodontal disease programs are predominantly conducted by oral health teams with limited collaboration across other health teams. Additionally, periodontal management activities, such as examinations and treatments, remain insufficient. Integration between oral health teams and other health teams within public health centers or private dental clinics should be improved.

This review underscores the integration of cognitive behavioral therapy (CBT) as a critical component of psychiatry residency programs essential for the comprehensive training of residents. The core competencies psychiatry residents should develop as CBT therapists, including specific skills and knowledge domains, are outlined. In addition, the review addresses the necessary attitudes and techniques for faculty engaged in CBT supervision, providing insight into effective educational and supervisory strategies. The application of these principles in clinical training settings is discussed, highlighting their potential to improve the quality and effectiveness of CBT training in psychiatry residency programs.

As the number of anterior cruciate ligament (ACL) reconstructions has increased significantly, surgical techniques have also made a lot of progress, and clinical outcomes are improving accordingly. However, the authors still have different opinions on ACL anatomy, femoral tunnel position, how to make a femoral tunnel, and graft selection, and many parts are controversial. Major factors contributing to the failure of ACL reconstruction, such as technical errors and biological healing failures. To reduce technical errors, a comprehensive understanding of ACL anatomy and the ability to create a well-positioned femoral tunnel are crucial. This involves recognizing the advantages and disadvantages of three surgical techniques: modified transtibial, transanteromedial portal, and outside-in. To improve biological healing, the four principles of tissue engineering (cells, growth factors, scaffolds, and mechanical stimuli) have been increasingly explored in various methods of bioaugmentation. Residual rotational instability of the knee joint remains a significant concern. Since the rediscovery of the anterolateral ligament (ALL) in the knee joint, the role of anterolateral complex, including the ALL and the deep iliotibial band, as secondary stabilizers of anterolateral rotatory instability, has gained attention. In the quest to reinforce the anterolateral complex, there are two approaches: ALL reconstruction as anatomical reconstruction concept and lateral extraarticular tenodesis as a nonanatomical reinforcement concept.

Background:
To evaluate the safety and effectiveness of empagliflozin in routine clinical settings, we collected and assessed the clinical profiles of Korean patients with type 2 diabetes mellitus.
Methods:
This was a post-marketing surveillance study of empagliflozin 10 and 25 mg. Information on adverse events and adverse drug reactions (ADRs) was collected as safety data sets. Available effectiveness outcomes, including glycosylated hemoglobin (HbA1c) level, fasting plasma glucose, body weight, and blood pressure, were assessed.
Results:
The incidence rate of ADRs was 5.14% in the safety dataset (n=3,231). Pollakiuria, pruritis genital, and weight loss were the most common ADRs. ADRs of special interest accounted for only 1.18%, and there were no serious events that led to mortality or hospitalization. In the effectiveness data set (n=2,567), empagliflozin significantly reduced the mean HbA1c level and body weight during the study period by –0.68%±1.39% and –1.91±3.37 kg (both P<0.0001), respectively. In addition, shorter disease duration, absence of dyslipidemia, and higher baseline HbA1c levels were identified as the clinical features characteristic of a “responder” to empagliflozin therapy.
Conclusion
Empagliflozin is a safe and potent glucose-lowering drug in routine use among Korean patients with type 2 diabetes mellitus. It is expected to have better glycemic efficacy in Korean patients with poorly controlled type 2 diabetes mellitus.
