A glandular odontogenic cyst (GOC) is a rare type of odontogenic cyst characterized by a broad clinical and pathological spectrum, overlapping with different lesions ranging from lateral periodontal cysts to low-grade mucoepidermoid carcinoma. Further, including GOC in the initial diagnosis is frequently challenging due to its nonspecific radiological results. Despite its rarity, accurate GOC diagnosis is crucial due to its aggressive nature and high recurrence potential. Therefore, various GOC cases need to be presented to clinicians. This study aims to report the clinical and radiological characteristics of two cases of GOCs that were initially misdiagnosed as radicular cysts.

This study evaluates the biomechanical effects of acellular dermal matrix (ADM) patch augmentation in a rotator cuff repair model and determines the effect of medial knot tying on time-zero stability. Methods: A biomechanical study was conducted using a porcine flexor digitorum profundus tendon model. Eighteen specimens were assigned to three groups: non-patched repair with medial row knot tying (n=5), patch-augmented repair without medial row knot tying (n=4), and patch-augmented repair with medial row knot tying (n=4). All repairs were performed using a standardized double-row suture bridge technique. Biomechanical testing assessed elongation, strain, load to failure, and construct stiffness at time zero. Results: Patch augmentation without medial row knot tying resulted in significantly greater tendon elongation (12.9±6.5 mm) than nonpatched repairs (5.0±5.3 mm, P=0.016) and patch-augmented repairs with medial row knot tying (4.4±4.4 mm, P=0.027). Similarly, strain was significantly higher in the patch-augmented group without medial knot tying (75.8%±42.9%) than in the non-patched repair (35.2%±38.9%, P=0.028) and patch-augmented repair with medial knot tying groups (29.1%±28.9%, P=0.052). However, load to failure did not differ significantly among the groups (P>0.05). Conclusions: ADM patch augmentation did not enhance time-zero mechanical strength in the tested conditions, though biomechanical advantages might emerge after integration to the tendon. In addition, patch augmentation without medial row knot tying showed the highest elongation and strain among groups, potentially reducing the stability of the repair.

In Walker’s nonmetric method, the nuchal crest serves as the representative region for indicating sexual dimorphism in cranial bones. However, the accuracy of sex estimation using the nuchal crest is lower than that using other anatomical regions. Furthermore, because of the protruding processes and structurally challenging features characterized by uneven and rough surfaces, there is a lack of metric methods for sex estimation, making quantification challenging. In this study, we aimed to validate a derived metric method for sex estimation by reconstructing the nuchal crest region in threedimensional (3D) images obtained from computed tomography scans of cranial bones and compare its accuracy with that of the nonmetric method. A total of 648 images were collected, with 100 randomly selected for use in the nonmetric method.We applied our metric method to the remaining 548 images. Our findings showed that the surface area of the nuchal crests was greater in male individuals than in female individuals. The nuchal crest surface area quantified by the metric method increased the accuracy of sex estimation by 48% compared with that by the nonmetric method. Our metric method for sex estimation, which quantifies the nuchal crest surface area using 3D images of the skull, led to a high sex estimation accuracy of 93%. Future studies should focus on proposing and quantifying new measurement methods for areas showing sexual characteristics in the skull that are difficult to measure, thereby enhancing the accuracy and reliability of sex estimation in human skeletal identification across various fields.
4.Clinical outcomes and future directions of enhanced recovery after surgery in colorectal surgery:a narrative review
The Ewha Medical Journal 2024;47(4):e69-
Enhanced recovery after surgery (ERAS) protocols are designed to minimize surgical stress, preserve physiological function, and expedite recovery through standardized perioperative care for primary colorectal surgery patients. This narrative review explores the benefits of current ERAS protocols in improving outcomes for these patients and provides insights into future advancements. Numerous studies have shown that ERAS protocols significantly reduce the length of hospital stays by several days compared to conventional care. Additionally, the implementation of ERAS is linked to a reduction in postoperative complications, including lower incidences of surgical site infections, anastomotic leaks, and postoperative ileus. Patients adhering to ERAS protocols also benefit from quicker gastrointestinal recovery, marked by an earlier return of bowel function. Some research indicates that colorectal cancer patients undergoing surgery with ERAS protocols may experience improved overall survival rates. High compliance with ERAS protocols leads to better outcomes, yet achieving full adherence continues to be a challenge. Despite these advantages, implementation challenges persist, with compliance rates affected by varying clinical practices and resource availability. However, the future of ERAS looks promising with the incorporation of prehabilitation strategies and technologies such as wearable devices and telemedicine. These innovations provide real-time monitoring, enhance patient engagement, and improve postoperative follow-up, potentially transforming perioperative care in colorectal surgery and offering new avenues for enhanced patient outcomes.

Paramyotonia congenita (PMC) is characterized by nondystrophic myotonia aggravated by exercise and cold exposure. SCN4A mutations manifest as various phenotypes of channelopathy, including PMC, myotonia congenita, and periodic paralysis. SCN4A-related channelopathy is characterized by autosomal dominant inheritance. Parental gonadal mosaicism is suspected in cases of recurrent de novo mutation in an autosomal dominantly inherited disease. We report a case of two Korean brothers presenting with PMC due to same de novo SCN4A point mutation, probably due to parental gonadal mosaicism.
