Background:
This study aimed to investigate the densitometric characteristics and qualitative bone status in patients with normocalcemic primary hyperparathyroidism (PHPT) compared with those in controls who were younger adults under 50 years.
Methods:
This retrospective study included 60 controls and 31 patients with PHPT who underwent dual energy X-ray absorptiometry (DXA) of the lumbar spine (LS), femoral neck (FN), and total hip (TH). Trabecular bone score (TBS) was derived from LS DXA images. Bone mineral density (BMD) values were assessed using Z-scores, and correlations between TBS, BMD, and laboratory parameters were examined.
Results:
The median ages of the control and PHPT groups were 41 and 42 years, respectively. The proportion of individuals classified as “below the expected range for age” based on Z-scores differed significantly between groups only when considering any site collectively. Median TBS was significantly lower in PHPT patients than in controls, even when BMD values at LS, FN, and TH fell within similar diagnostic categories. In controls, TBS and BMD demonstrated very low correlation coefficients. In contrast, PHPT patients showed a stronger correlation between TBS and femoral BMD, whereas the association between TBS and LS BMD was largely absent. Among laboratory markers, only serum intact parathyroid hormone was significantly negatively correlated with TBS.
Conclusions
Young adults with PHPT exhibit impaired bone quality despite relatively preserved BMD, suggesting early microarchitectural deterioration. These findings support the combined use of LS and femoral BMD with TBS for more accurate assessment of skeletal health in PHPT.

This study evaluates the effectiveness of Therapeutic Hypothermia (TH) in treating poor-grade aneurysmal subarachnoid hemorrhage (SAH), focusing on functional outcomes, mortality, and complications such as vasospasm, delayed cerebral ischemia (DCI), and hydrocephalus. Methods: Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines, a comprehensive literature search was conducted across multiple databases, including Medline, Embase, and Cochrane Central, up to November 2023. Nine studies involving 368 patients were selected based on eligibility criteria focusing on TH in poor-grade SAH patients. Data extraction, bias assessment, and evidence certainty were systematically performed. Results: The primary analysis of unfavorable outcomes in 271 participants showed no significant difference between the TH and standard care groups (risk ratio [RR], 0.87). However, a significant reduction in vasospasm was observed in the TH group (RR, 0.63) among 174 participants. No significant differences were found in DCI, hydrocephalus, and mortality rates in the respective participant groups. Conclusions: TH did not significantly improve primary unfavorable outcomes in poor-grade SAH patients. However, the reduction in vasospasm rates indicates potential specific benefits. The absence of significant findings in other secondary outcomes and mortality highlights the need for further research to better understand TH's role in treating this patient population.

BACKGROUND/OBJECTIVES:
Okra seed is a rich source of various nutritional and bioactive constituents, but its mechanism of action is still unclear. The aim of this study was to evaluated the effects on glucose uptake and serum lipid profiles of unsaponifiable matter (USM) from okra seed in adipocytes and diabetic animal models.MATERIALS/METHODSUSM was prepared from okra seed powder by saponification. The contents of phytosterols and vitamin E in USM were measured. 3T3-L1 preadipocytes were cultured for 6 days with different concentrations of USM (0–200 μg/mL). The diabetic rats were administered with or without USM for 5 wk.
RESULTS:
In the USM, the contents of phytosterols and vitamin E were 394.13 mg/g USM and 31.16 mg/g USM, respectively. USM showed no cytotoxicity and led to an approximately 1.4-fold increase in glucose uptake in 3T3-L1 adipocytes. The treatment of USM also increased the expressions of peroxisome proliferator-activated receptor-γ and glucose transporter-4 in a dose-dependent manner in adipocytes. The body weight change was not significantly different in all diabetic rats. However, blood glucose and the weights of liver and adipose tissues were significantly reduced compared to those in the control diabetic rats. Treatment with USM decreased the levels of triglycerides, total cholesterol, and low-density lipoprotein cholesterol compared to the control group. The USM group also showed significantly decreased atherogenic indices and cardiac risk factors.
CONCLUSION
These results suggest that USM from okra seed improves the hypoglycemic and hypolipidemic effects in diabetic rats, and provides valuable information for improving the functional properties of okra seed.

An esophageal duplication cyst (EDC) is a congenital anomaly of the foregut. EDCs are often asymptomatic, so they are found incidentally on chest radiographs. In symptomatic patients, EDCs present with cough, dyspnea, vomiting, dysphagia, and chest pain. Potential complications of EDCs include perforation, obstruction, bleeding, and infection. The rarity of this condition may hinder timely diagnosis, which may lead to life-threatening complications. This article describes a case of esophagitis and mediastinitis developed in a 12-month-old infant with an EDC. We emphasize that although rare, EDCs should be considered in the differential diagnosis of non-specific respiratory signs such as cough, dyspnea, and stridor.

Objectives:
. To train participants to localize sound using virtual reality (VR) technology, appropriate auditory stimuli that contain accurate spatial cues are essential. The generic head-related transfer function that grounds the programmed spatial audio in VR does not reflect individual variation in monaural spatial cues, which is critical for auditory spatial perception in patients with single-sided deafness (SSD). As binaural difference cues are unavailable, auditory spatial perception is a typical problem in the SSD population and warrants intervention. This study assessed the applicability of binaurally recorded auditory stimuli in VR-based training for sound localization in SSD patients.
Methods:
. Sixteen subjects with SSD and 38 normal-hearing (NH) controls underwent VR-based training for sound localization and were assessed 3 weeks after completing training. The VR program incorporated prerecorded auditory stimuli created individually in the SSD group and over an anthropometric model in the NH group.
Results:
. Sound localization performance revealed significant improvements in both groups after training, with retained benefits lasting for an additional 3 weeks. Subjective improvements in spatial hearing were confirmed in the SSD group.
Conclusion
. By examining individuals with SSD and NH, VR-based training for sound localization that used binaurally recorded stimuli, measured individually, was found to be effective and beneficial. Furthermore, VR-based training does not require sophisticated instruments or setups. These results suggest that this technique represents a new therapeutic treatment for impaired sound localization.

Acute pancreatitis (AP) rarely occurs in association with food allergy (FA), and the mechanism is not clearly explored. We herein report a rare case of egg protein-induced AP. A 5-year-old girl was brought to the hospital because of tongue pruritus and an increased level of egg white-specific immunoglobulin E. During an oral food challenge, she developed hives, abdominal pain and vomiting after ingestion of a cumulative of 610 mg of boiled egg white (70 mg of protein). After management with intramuscular injection of epinephrine and orally administered prednisolone and levocetirizine, her skin symptoms improved. The next day, blood tests showed elevated levels of amylase and lipase, and computed tomography revealed a swollen pancreas with a low-attenuated necrotic portion. She was diagnosed with AP and treated with food restriction, intravenous methylprednisolone and gabexate mesilate. The serum levels of amylase and lipase were reduced to normal levels on day 5 and her symptoms completely resolved on day 10. A suspicion of food-induced AP is required for correct diagnosis and proper management in children with FA when they manifest severe abdominal pain.

Recurrent respiratory papillomatosis (RRP) is a chronic disease related to human papillomavirus infection. The standard treatment of RRP is surgical resection of the lesion, but due to frequent recurrence, a combination of various adjuvant therapies has been attempted. Herein, we present the first case of RRP to whom intravenous cidofovir was administered as an adjuvant therapy in Korea. A 9-year-old boy was admitted due to hoarseness, stridor and breathing difficulty. At 10 months of age, he was diagnosed with RRP in the upper airway and thereafter he had repeatedly undergone surgical removal. During this hospitalization, papilloma was found again from the superior glottis to the inferior glottis and surrounding the trachea at the age of 9 years. In addition, well-defined nodular lesions were newly found on both lung fields, and a pathologic examination revealed a squamous papilloma with highgrade dysplasia, human papilloma virus types 6, 11, and 40 (low-risk type). Because of the frequent recurrence of papilloma in the upper airway as well as lung involvement, he underwent 38 injections of intravenous cidofovir for 2 years. During treatment, the intervals required for surgical removal of the mass causing upper airway obstruction were prolonged from an average of 37.3 to 74.6 days without serious side effects. However, intravenous cidofovir treatment had no effect on the lung lesion. This case shows that an intravenous cidofovir administration can be used as an adjuvant therapy in a child with RRP to relieve the upper airway obstruction, although this treatment does not cure the disease.
