Cedar pollen is known as a typical allergen that causes various allergic symptoms in the nasal mucosa, conjunctiva, and skin. However, inflammation of the vulvar mucosa due to sensitization to cedar pollen is not well-known. We experienced two cases in which the detection of cedar pollen during microscopic urine sediment examination led to the diagnosis of allergic vulvovaginitis caused by cedar pollen.

- This study investigated the dynamic rotational motion of the forearm to understand how the radius and ulna interact and the role of the interosseous membrane (IOM).
- Using advanced imaging techniques on 20 arms from 10 healthy participants, researchers found the average range of forearm rotation was about 150° for both dominant and non-dominant hands, with no significant differences.
- The findings revealed that the radius shifts during rotation, with specific changes in the IOM's components, enhancing knowledge about forearm mechanics and the anatomical function of the IOM.
Purpose: Ultrasound-guided supraclavicular brachial plexus block (SCBPB) is performed by surgeons for upper limb anesthesia; however, certain patients need additional local anesthesia. This study aimed to identify risk factors for additional local anesthetic injection requirements.
Methods: In total, 269 patients receiving ultrasound-guided SCBPB were enrolled.
Article Synopsis
- - Atypical ulna fractures (AUF) are uncommon and linked to long-term use of bisphosphonates, with unclear development mechanisms.
- - An 85-year-old woman on oral alendronate for 8 years, without vitamin D, experienced an atraumatic ulna fracture while doing kitchen work, along with severe spinal deformities.
- - The study suggests that sustained local stress on the ulna, compounded by the effects of bisphosphonates and vitamin D deficiency, may contribute to the development of AUF.
Article Synopsis
- The study focuses on exploring the link between vitamin D deficiency and the severity of distal radius fractures (DRFs) in women over 45 years old.
- It found that patients with severe fractures (articular comminuted) had significantly lower levels of serum 25-hydroxyvitamin-D compared to those with less severe fractures.
- The researchers concluded that vitamin D supplementation could potentially help prevent more severe types of fractures due to its association with lower vitamin D levels.
Article Synopsis
- The study evaluated the tolerability of a once-yearly infusion of zoledronic acid (ZA) 5 mg for preventing fractures after hip surgery, focusing on side effects like acute-phase reactions (APRs) and calcium levels.
- Researchers analyzed 84 patients (average age 83) and found APRs in 11.9% of cases, primarily showing symptoms like fever; hypocalcemia occurred in 6% of patients a week after the infusion.
- Results indicated that increased inflammatory markers post-surgery and higher bone turnover may raise the risks of APRs and low calcium levels, but overall, the infusion was deemed well tolerated with supportive care.
Comparing the locking screw direction of three locking plates for lateral clavicle fractures: a simulation study.
BMC Musculoskelet Disord
September 2021
Article Synopsis
- The study focused on analyzing three different locking plates for treating lateral clavicle fractures, specifically looking at their screw angles and the maximum number of screws that can be used based on the size of the bone fragments.
- Researchers measured screw angles in both the coronal and sagittal planes and simulated their placement on 3D clavicle models with varying lateral fragment sizes (10-30 mm).
- Results showed that the distal clavicle plate accommodated the most screws and covered the largest area on the clavicle's underside, indicating its effectiveness for larger fragments compared to the other plates.
Article Synopsis
- This study evaluated the angles between screws and plates in 16 types of volar locking plates (VLPs) to determine how small intra-articular fragments can be fixed during surgery.
- The researchers measured ulnar orientation and elevation angles, analyzing relationships to identify fixable fragment sizes in distal radius models simulated by two surgeons.
- Findings showed that variable-angle VLPs, particularly from Depuy Synthes, allow better fixation of small fragments, while fixed-angle VLPs like Mizuho's are better for specific fragment types, influencing surgical choices.
Article Synopsis
- The study investigates missed Monteggia fractures (MMF), focusing on how prolonged radial head dislocation impacts the length discrepancy between the radius and ulna bones.
- It categorizes 24 patients into two groups based on the duration of dislocation and measures the lengths of the bones to analyze discrepancies.
- Findings reveal that in cases of long-standing dislocation, the ulna on the affected side is shorter, indicating a need for ulnar lengthening to correct the discrepancy and avoid complications during surgery.
Unlabelled: During elbow procedures, reconstruction of the joint (including the articular cartilage) is important in order to restore elbow function; however, the regional distribution of elbow cartilage is not completely understood. The purpose of the present study was to investigate the 3-dimensional (3-D) distribution patterns of cartilage thickness of elbow bones (including the distal part of the humerus, proximal part of the ulna, and radial head) in order to elucidate the morphological relationship among them.
Methods: Two 3-D surface models were created with use of a laser scanner: (1) a cartilage-bone model based on 20 elderly cadaveric elbows exhibiting normal cartilaginous conditions and (2) a bone model that was created after dissolving the cartilage.
Background: The identification and precise removal of bony impingement lesions during arthroscopic débridement arthroplasty for elbow osteoarthritis is technically difficult. Surgical navigation systems, combined with preoperative 3-dimensional (3D) assessment of bony impingements, can provide real-time tracking of the surgical instruments and impingement lesions. This study aims to determine the registration accuracy of the navigation system for the humerus and ulna during elbow arthroscopy.

We proposed biplane fluoroscopic intensity-based 2D-3D matching, which employs automatic registration processing using the evolutionary optimization strategy.

We aimed to elucidate the mechanism of rotational restriction by retrospective analysis of 23 patients with unilateral malunited DRFs who presented restricted forearm rotation. We conducted computed tomography during forearm rotation on both sides.

Methods: We retrospectively analyzed the cases of 18 patients with malunited forearm diaphyseal fractures and rotational restriction. All patients underwent bilateral computed tomography (CT) of the forearm in maximum supination, pronation, and neutral positions.
Article Synopsis
- - The partial physeal arrest of the distal radius can lead to serious wrist deformities and functional issues over time.
- - Physeal bar resection, known as the Langenskiöld procedure, is the most common surgery for this condition, but it can be technically challenging.
- - This paper discusses a new method for the Langenskiöld procedure that uses a patient-specific guide and intramedullary endoscopy to improve the surgical process and outcomes.
The purpose of this study was to investigate the differences in three-dimensional carpal kinematics between type 1 and 2 lunates. We studied 15 instances of wrist flexion to extension (nine type 1, six type 2), 13 of radial to ulnar deviation (seven type 1, six type 2), and 12 of dart-throwing motion (six each of type 1 and 2) in 25 normal participants based on imaging with computerized tomography. Mean proximal translation of the distal articular midpoint of the triquetrum relative to type 2 lunates during wrist radioulnar deviation was 2.

In this study, we examined the relationship between the level of narcissism and justifiability evaluation of anger expression. Participants, 313 students, were asked to rate the justifiability of a variety of anger expressions by them as suffering victims, and answer the Narcissistic Personality Inventory-Short Version (NPI-S). Results indicated that the higher the sense of superiority and competence, which was an aspect of personality, the more justifiable they felt their unilateral expression of anger was.

Japanese undergraduate students (N= 229) responded to a questionnaire on how they express anger in daily life. Analysis indicated the group who reported a lower tendency to feel anger (the Low group) reported reappraisals such that Damage to Self was less severe, and Instigator's Responsibility was smaller than that for the group who reported a higher tendency (the High group), which suggested that people who tend to feel less anger use reappraisals to reduce their anger after expression more than those who tend to feel more anger.
