Clinical Characteristics and Prognosis of Infants and Children <3 Years of Age With Thyroglossal Duct Cyst Complicated With a Parapharyngeal Mass: A Case Series Study.

Thyroglossal duct cysts (TGDCs) are congenital and developmental abnormalities in infants and young children. This retrospective case series study examined the characteristics of 7 patients <3 years (mean age, 1.9 years) with TGDC complicated with a parapharyngeal mass treated at one hospital between January 2019 and 2022. Four patients had a painless mass around the neck, 2 had a painless mass associated with snoring, and 1 presented repeated swelling and pain. B-ultrasound suggested 6 cases of TGDC and 1 possible lymphangioma. All patients were treated with Sistrunk surgery to remove the TGDC. Six patients had no cyst recurrence during follow-up (6 months to 2 years). In conclusion, TGDC complicated with a parapharyngeal mass has complex and variable clinical manifestations. Completely removing the cyst while sparing thyroid cartilage and surrounding vascular and neuroanatomical structures is important to avoid complications. The patients are likely to be free from recurrence after surgery.

Molecular mechanisms affecting the stability of high internal phase emulsions of zein-soy isoflavone complexes fabricated with ultrasound-assisted dynamic high-pressure microfluidization.

In this study, zein-soy isoflavone complex (ZSI) emulsifiers were fabricated using ultrasound-assisted dynamic high-pressure micro fluidization to stabilise highinternal phase pickering emulsions. Ultrasound-assisted dynamic high-pressure micro-fluidization enhanced surface hydrophobicity, zeta potential, and soy isoflavone binding capacity, while it decreased particle size, especially during ultrasound and subsequent microfluidization. The treated ZSI could produce small droplet clusters and gel-like structures, with excellent viscoelasticity, thixotropy and creaming stability owing to their neutral contact angles. Ultrasound and subsequent micro fluidization treatment of the ZSI complexes were highly effective in preventing droplet flocculation and coalescence after long-term storage or centrifugation due to their higher surface load, thicker multi-layer interfacial structure, and stronger electronic repulsion between the oil droplets. This study provides insights and extends our current knowledge of how non-thermal technology affects the interfacial distribution of plant based particles and the physical stability of emulsions.

Clinical Efficacy and Safety of Different Dental Prosthetic Membranes in Guided Bone Regeneration during Dental Implants: A Meta-Analysis.

Objective. To evaluate clinical efficacy and safety of absorbable and non-absorbable dental restorative membranes in guided bone regeneration (GBR). Articles concerning absorbable and non-absorbable prosthetic membrane-related studies of GBR were screened from multiple databases. In the end, 526 postoperative patients who met eligibility criteria were screened for the study from eight trials. The results showed that the repair success rate of the experimental group (absorbable dental restorative membrane) was higher than that of the control group (non-absorbable dental restorative membrane) (RR = 1.18, 95% CI [1.11,1.26], and the total physical therapy effect was P < 0.0001, I 2 = 0%), and the height of bone graft in the experimental group was higher than that in the control group (MD = 0.67, 95% CI [0.11, 1.23]). The thickness of bone graft in the experimental group was higher than that in the control group (MD = 0.43, 95% CI [0.30,0.56], P < 0.00001, I 2 = 61%), and the adverse events in the experimental group were less than those in the control group (RR = 0.31, 95% CI [0.18, 0.51], P < 0.00001, I 2 = 13%). Absorbable prosthetic membrane is superior to non-absorbable prosthetic membrane in clinical efficacy and safety.
