Purpose: Arm wrestling is a common strength competition, particularly among young men, including military personnel.While previous studies have examined humeral shaft fractures from arm wrestling or in soldiers, no research has focused on both. This study evaluates the outcomes of dual plating fixation via the anterolateral approach for arm wrestling-induced fractures in soldiers. Methods: This retrospective study included 18 male patients (mean age, 21.7 years) treated at the Armed Forces Daejeon Hospital (May 2022–December 2023). Data on rank, radial nerve injury, fracture type (AO-OTA classification), and clinical outcomes (union time, radial nerve recovery, DASH score) were analyzed. Results: The cohort included 12 soldiers, two non-commissioned officers, and four officers. Common fracture types were A1 and B1, with four cases of radial nerve palsy. Union occurred at 12.5 weeks, and nerve recovery averaged 15 weeks. No cases of non-union or persistent nerve damage were observed. Conclusion Arm wrestling carries a high risk of humeral fractures in soldiers. Awareness and preventive measures should be emphasized. The dual plating fixation technique via the anterolateral approach is highly effective, demonstrating excellent union and recovery outcomes.

Portal vein tumor thrombosis (PVTT) is an uncommon condition in which tumor cells expand into the vessels, causing blood clot formation in the portal vein. PVTT is mainly associated with hepatocellular carcinoma, leading to an unfavorable prognosis; however, it can also develop in patients with other cancer types. Herein, we report a case of metastatic renal cell carcinoma diagnosed by a blind liver biopsy in a patient with dynamic computed tomography-confirmed portal vein thrombosis and cholangiopathy. This case illustrates the importance of systematic surveillance with routine laboratory tests and contrast-enhanced imaging studies on patients with cancer to detect potential liver infiltration of metastatic cancer.

Background: Although the Korean Society for Cytopathology has developed educational goals as guidelines for cytopathology education in Korea, there is still no systematic approach to cytopathology education status for pathology residents. Furthermore, satisfaction with cytopathology education and with the outcome of the current training/educational program has not been investigated in Korea. This study aimed to obtain comprehensive data on the current state of cytopathology education for residents and evaluate education outcomes. Methods: An online survey was conducted in December 2020 for the board-certified pathologists and training residents registered as members of the Korean Society for Cytopathology. The questionnaire comprised questions that investigated the current status of cytopathology at each training institution, the degree of satisfaction with the work and education related to cytopathology, outcomes of cytopathology training, and educational accomplishments. Results: Of the participants surveyed, 12.3% (132/1,075) completed the questionnaire, and 36.8% (32/87) of cytopathology residents participated. The mean overall satisfaction with cytopathology education was 3.1 points (on a 1- to 5-point scale, 5: very satisfied). The most frequent suggestion among the free description format responses was to expand educational opportunities, such as online education opportunities, outside of the individual institutions. Conclusions Our results showed that cytopathology training in Korea needs further improvement. We expect that this study will inform systematic training of competent medical personnel armed with broad cytopathology knowledge and strong problem-solving abilities.

Purpose: This study investigated the immediate biomechanical effects of unilateral mastication for 10 minutes on the temporomandibular joint (TMJ) with 21 healthy adult participants. Methods: The gum group chewed gum on the right side for 10 minutes, and the control group rested for 10 minutes. Biomechanical data were obtained using a three-dimensional infrared camera before and after intervention. An independent t-test assessed the variation of kinematic data to identify differences between before and after intervention. Results: Among biomechanical variables, the gum group’s length of the left forehead middle region and the temporomandibular joint angle decreased compared to the control group (p<0.05). Conclusion Caution with unilateral masticatory activity is recommended, as unilateral mastication causes biomechanical changes due to excessive load on the soft tissues of the contralateral TMJ.

Purpose: To investigate the long-term outcomes of anterior chamber angle parameters in patients with primary angle closure glaucoma (PACG) after peripheral laser iridotomy (LI) combined with iridoplasty (PI) using a dual Scheimpflug analyzer. Methods: This retrospective study included 32 eyes in 32 patients diagnosed with PACG who underwent LI plus PI. Patients with an acute angle closure crisis were excluded. Dual Scheimpflug analyzer images were acquired before and 1 week after LI plus PI, and yearly afterwards. Anterior chamber depth (ACD) and volume (ACV), mean anterior chamber angle (ACA), and intraocular pressure (IOP) were also measured. Results: The mean follow-up was 32.28 ± 13.34 months. Baseline demographics were age 63 ± 7.9 years, 62.5% female, IOP 15.48 ± 4.79 mmHg, ACD 2.09 ± 0.19 mm, and visual field mean deviation -7.97 ± 8.49 dB. ACD increased from baseline to 2.15 ± 0.32 mm, but it was not significant (p = 0.136). ACV increased significantly from 78.32 ± 11.49 mm at baseline to 83.04 ± 11.16 mm at the last visit after LI (p = 0.011). The mean ACA increased significantly from 26.86 ± 2.53° at baseline to 28.82 ± 4.64° at the last visit (p = 0.022). IOP decreased significantly from baseline to 13.06 ± 2.21 mmHg at the last visit (p = 0.001). Conclusions The ACA parameters improved after LI combined with PI in patients with PACG and remained so on long-term follow-up. IOP was also significantly reduced for more than 2.5 years after LI plus PI.

Background: This prospective randomized controlled study aimed to determine the effects of abdominal massage on constipation management in elderly patients with hip fractures. Methods: From August 2017 to December 2018, patients aged above 65 years with hip fractures (n = 88) were randomly assigned to a massage group that received a bowel massage (n = 48) or a control group that did not receive a bowel massage (n = 40). Patients in the bowel massage group received a bowel massage from a trained caregiver after breakfast at approximately 9:00 AM for an hour. On admission, 5 days after surgery, and on the day of discharge, the patient’s normal and actual defecation pattern, stool consistency, and any problems with defecation were assessed through a structured interview. The questionnaire comprising the Bristol Stool Scale, patient assessment of constipation, time to defecation, medication for defecations, failure to defecate, cause of admission, admission period, and date of surgery were recorded. Statistical analyses were performed 5 days after surgery and on the day of discharge. Results: The mean age of the study cohort was 81.4 years (range, 65–99 years). The number of constipation remedies was significantly lower in the massage group than in the control group on postoperative day (POD) 5 and at discharge (9 vs. 15, p = 0.049 and 6 vs. 11, p = 0.039, respectively). The number of defecation failures was significantly lower in the massage group than in the control group (10 vs. 17, p = 0.028) on POD 5. However, the number of defecation failures at discharge was not significantly different between the two groups ( p = 0.131). The development of postoperative ileus ( p = 0.271) and length of hospital stay ( p = 0.576) were not different between the groups. Conclusions The number of constipation remedies was significantly lower in the massage group than in the control group on POD 5 and discharge, and the number of defecation failures was significantly lower in the massage group than in the control group on POD 5. Therefore, abdominal massage may be considered as an independent nursing initiative for constipation management.
