Background: Subdural to peritoneal shunt (SPS) placement is an established treatment option for chronic subdural hematoma (SDH) in the pediatric population. Practice patterns vary between institutions, with some advocating shunt removal while others leave the SPS in place after SDH resolution. There remain a paucity of data to document the safety and outcomes after removal of SPS.
Objective: To support the safety and efficacy of SPS placement and subsequent removal for chronic SDH in children younger than 2 years.
Methods: A total of 26 patients younger than 2 years underwent SPS removal procedures over a 5-year period from 2015 to 2019 at a single institution. Patient characteristics, hospital course, and outcomes were prospectively recorded in the hospital electronic medical record. Attention was given to change in head circumference, size of subdural collection, need for reoperation, or complications because of shunt removal.
Results: Patients who underwent SPS placement presented with macrocephaly, signs and symptoms of increased intracranial pressure, and radiographical evidence of subdural collections. The most common etiology of chronic SDH was nonaccidental head trauma (18 of 26 patients). SDS was kept in place for an average of 10 months. Resolution of SDH was demonstrated on imaging for all 26 patients. One patient did require reinsertion of SPS 2 weeks after SPS removal.
Conclusion: Removal of SPS remains controversial, and careful consideration of patient, family, and provider preferences and potential risks associated with SPS removal must be taken into consideration.

The integrity and phenotype of periodontal soft tissues significantly influence the outcome of surgical periodontal regenerative therapy. In cases with thin gingival phenotype, treating infrabony defects surgically can worsen gingival recession and loss of papillae. This report outlines a surgical approach for addressing infrabony defects at sites with gingival recession and thin phenotype.

The inflow and infiltration (I&I) is an issue for many urban sewer networks (USNs), which can significantly affect system functioning. Placing sensors within the USNs is a typical approach to detect large I&I event, but deploying a limited number of sensors while achieving maximum detection reliability is challenging. While some methods are available for sensor placement, they are generally heuristic search-based methods (HSBMs) and hence the resultant sensor placement strategies (SPSs) are variable over different algorithm runs or parameterizations.

Article Synopsis
- The research aimed to compare two existing stereotactic brain biopsy (SBB) methods (3D-SCG and neuronavigation with Brainsight) against a new method using Brainsight with a 3D-printed headframe (BS3D-HF) for canine cadavers.
- The study involved five canine cadavers, with initial CT scans taken, followed by the placement of pins at selected target points using each method, and then a repeat CT to assess accuracy.
- Results showed that both 3D-SCG and neuronavigation had comparable median deviations (2.48 mm and 3.28 mm), while the BS3D-HF had a much larger median deviation (14.8 mm), indicating
We achieved significant enhancements in green light emission (550 nm) from InGaN/GaN quantum wells (QWs) by tuning the localized surface plasmon resonance (LSPR) of self-assembled Ag nanoparticles (NPs) through the application of a SiO thin film. The LSPR wavelength of Ag NPs was shifted towards shorter wavelengths by 80 nm using a 5 nm SiO layer to separate Ag NPs from GaN surface, thereby aligning it effectively with the green region. This strategic placement of Ag NPs and a 5 nm SiO film resulted in significant enhancements of photoluminescence (PL) by 15- and 8.

Introduction: Preventing potential foreign animal diseases is a high priority, with re-emerging threats such as African Swine Fever emerging close to North American borders. The Secure Pork Supply (SPS) plan provides a voluntary framework for swine producer biosecurity planning and disease outbreak preparedness. However, biosecurity knowledge varies greatly among swine veterinarians, managers, and caretakers within the industry, which impacts the understanding, quality, implementation and biosecurity plan agreements with the SPS guidelines unless review procedures and quality control mechanisms are in place.
