Purpose:
This study compared the outcomes of three commonly used reconstructive techniques—the thenar flap, partial toe pulp free flap, and radial artery superficial palmar (RASP) flap—for the reconstruction of fingertip and pulp defects, in order to provide guidance for surgeons in selecting the appropriate method based on defect size and patient characteristics.
Methods:
A retrospective chart review was conducted on 50 patients who underwent fingertip or pulp reconstruction. Nine patients received thenar flaps, 26 received partial toe pulp free flaps, and 15 received RASP flaps. Patient demographics, defect size, flap survival, donor site morbidity, and patient satisfaction were analyzed.
Results:
All flaps survived. In the RASP flap group, three cases of partial necrosis were successfully managed without additional surgical interventions. The thenar flap group had donor site pain and joint stiffness, while the partial toe pulp free flap group exhibited no donor site complications. The RASP flap group experienced hypertrophic scarring in five cases. Patient satisfaction was high across all groups, with the partial toe pulp free flap yielding the most positive outcomes.
Conclusion
The thenar flap is a reliable option for small defects, especially those with exposed bone, but is associated with donor site morbidity and joint stiffness. The partial toe pulp free flap provides superior functional and aesthetic results for moderate defects, though it requires more surgical expertise and has a longer recovery time. The RASP flap is optimal for larger defects, offering good cosmetic results but requiring careful donor site management to avoid hypertrophic scarring.

Annals of Laboratory Medicine 2024;44(3):222-234
Background:
Flow cytometric immunophenotyping of hematolymphoid neoplasms (FCIHLN) is essential for diagnosis, classification, and minimal residual disease (MRD) monitoring. FCI-HLN is typically performed using in-house protocols, raising the need for standardization. Therefore, we surveyed the current status of FCI-HLN in Korea to obtain fundamental data for quality improvement and standardization.
Methods:
Eight university hospitals actively conducting FCI-HLN participated in our survey.We analyzed responses to a questionnaire that included inquiries regarding test items, reagent antibodies (RAs), fluorophores, sample amounts (SAs), reagent antibody amounts (RAAs), acquisition cell number (ACN), isotype control (IC) usage, positiveegative criteria, and reporting.
Results:
Most hospitals used acute HLN, chronic HLN, plasma cell neoplasm (PCN), and MRD panels. The numbers of RAs were heterogeneous, with a maximum of 32, 26, 12, 14, and 10 antibodies used for acute HLN, chronic HLN, PCN, ALL-MRD, and multiple myeloma-MRD, respectively. The number of fluorophores ranged from 4 to 10. RAs, SAs, RAAs, and ACN were diverse. Most hospitals used a positive criterion of 20%, whereas one used 10% for acute and chronic HLN panels. Five hospitals used ICs for the negative criterion. Positiveegative assignments, percentages, and general opinions were commonly reported. In MRD reporting, the limit of detection and lower limit of quantification were included.
Conclusions
This is the first comprehensive study on the current status of FCI-HLN in Korea, confirming the high heterogeneity and complexity of FCI-HLN practices. Standardization of FCI-HLN is urgently needed. The findings provide a reference for establishing standard FCI-HLN guidelines.

Total gastrectomy has been a standard treatment for upper-third early gastric cancer for decades. Supplementation is essential after total gastrectomy due to vitamin B12 deficiency. Additionally, postoperative complications, such as reflux esophagitis, anastomotic stricture, leakage, and malnutrition, are the main issues. Proximal gastrectomy is considered an alternative treatment for upper-third early gastric cancer. As a function-preserving gastrectomy it is known that the incidence of vitamin B12 deficiency is low and due to its various reconstruction methods we can easily overcome major postoperative complications. Therefore, we aimed to review about proximal gastrectomy, how it is reconstructed, and complications after reconstruction.

Purpose:
This study aimed to conduct a systematic literature review and meta-analysis of the exercise intervention effects for the prevention of musculoskeletal injuries in military personnel.
Methods:
Among studies that included military personnel as participants, we identified randomized controlled trials (RCTs) and cluster-RCT studies that used exercise interventions as a method for injury prevention. Exercise encompassed all types of physical activity, and the effect size was determined by the ratio of injuries between groups.Literature searches were conducted with search terms modified to ensure common inclusion of keywords such as “Soldier,” “Injury prevention,” and “Exercise.” For the analysis of potential factors, variables selected for group differentiation included gender, risk of bias, exercise volume, injury location, exercise type, and study design.
Results:
Among a total of 8,598 search results, 10 papers were finally confirmed. The meta-analysis of all 10 papers showed that there was no statistically significant injury prevention effect, and significant heterogeneity was observed among the studies (incidence rate ratio, 0.82; 95% confidence interval, 0.62–1.09, I2 =83%). Subgroup analysisrevealed a significant 44% reduction in injuries in studies where exercise volume for injury prevention was relatively high. However, no significant injury prevention effects were observed in other potential factors between groups.
Conclusion
The results of this study suggest that the effectiveness of injury prevention exercises in military settings was not statistically significant. However, through the analysis of potential factors, it was confirmed that increasing the time spent on injury prevention exercises may have a preventive effect on injuries.

Penetrating brain injury (PBI) is a rare type of traumatic brain injury, which accounts for 0.4% of all head trauma cases. In this study, we describe a 14-year-old male adolescent who sustained a transorbital penetrating injury caused by a fencing knife. Although the patient visited the hospital after the foreign body had been removed, we diagnosed a PBI based on identification of a linear injury trajectory extending from an orbital roof fracture to the contralateral parietal lobe, using three-dimensional reconstruction of the hemorrhage. The patient fully recovered after conservative treatment. We hope that sharing our experience will serve as a guideline for the clinical management of PBI.

Traumatic brain injury (TBI) is a major global health concern. Due to the increase in TBI incidence and the aging population, an increasing number of patients with TBI are taking antithrombotic agents for their underlying disease. When TBI occurs in patients with these diseases, there is a conflict between the disease, which requires an antithrombotic effect, and the neurosurgeon, who must minimize intracranial hemorrhage. Nevertheless, there are no clear guidelines for the reversal or resumption of antithrombotic agents when TBI occurs in patients taking antithrombotic agents. In this review article, we intend to classify antithrombotic agents and provide information on them. We also share previous studies on the reversal and resumption of antithrombotic agents in patients with TBI to help neurosurgeons in this dilemma.

Purpose:
The incidence of early-onset colorectal cancer (CRC) and associated mortality have been increasing. However, the potential benefits of CRC screening are largely unknown in young individuals. We aimed to evaluate the effect of CRC screening with colonoscopy on all-cause and CRC mortality among young (aged < 45 years) and older (aged ≥ 45 years) individuals.
Materials and Methods:
This cohort study included 528,046 Korean adults free of cancer at baseline who underwent a comprehensive health examination. The colonoscopic screening group was defined as those who reported undergoing colonoscopy for CRC screening. Mortality follow-up until December 31, 2019 was ascertained based on nationwide death certificate data from the Korea National Statistical Office.
Results:
Colonoscopic screening was associated with a lower risk of all-cause mortality in both young and older individuals. Multivariable-adjusted time-dependent hazard ratios (95% confidence intervals) for all-cause mortality comparing ever- to never-screening were 0.86 (0.75-0.99) for young individuals and 0.71 (0.65-0.78) for older individuals. Colonoscopic screenings were also associated with a reduced risk of CRC mortality without significant interaction by age, although this association was significant only among participants aged ≥ 45 years, with corresponding time-dependent hazard ratios of 0.47 (0.15-1.44) for young individuals and 0.52 (0.31-0.87) for those aged ≥ 45 years.
Conclusion
Colonoscopic CRC screening decreased all-cause mortality among both young and older individuals, while significantly decreased CRC mortality was observed only in those aged ≥ 45 years. Screening initiation at an earlier age warrants more rigorous confirmatory studies.
