Purpose: To characterize the patterns of demographic data, dermatologic diagnosis, and disposition regarding pediatric dermatological presentations in an emergency department (ED) at Armadale Health Service, a secondary outer metropolitan hospital in Perth, Western Australia. Methods: Retrospective cross-sectional study auditing pediatric dermatological presentations to the ED from December 2022 through November 2023. We analyzed the age group, sex, dermatologic diagnosis, Australasian Triage Scale, ED length of stay, and disposition. The age group comprised infants, preschoolers, schoolers, and adolescents. The diagnosis included anaphylaxis and angioneurotic edema (AAE), allergy-related and urticarial dermatitis (AUD), eczema and other dermatitis (EOD), infective dermatoses, and not elsewhere classified. Results: Of the 540 pediatric patients who presented to the ED with a dermatological complaint, 44.4% were girls with a median age of 4.5 years (interquartile range, 1.5-9.3) and a hospitalization rate of 7.6%. The dermatologic diagnoses consisted of AUD (34.3%), infective dermatoses (29.3%), EOD (23.3%), AAE (8.5%), and not elsewhere classified (4.6%). Most patients were triaged as an Australasian Triage Scale category 3-4, with a median ED length of stay of 2.3 hours (1.5-3.5 hours). Pairwise comparisons showed differences in the diagnoses between infants and preschoolers and between schoolers and adolescents for EOD and infective dermatoses (P < 0.001). The hospitalized patients showed a higher proportion of AAE, EOD, and infective dermatoses than those discharged (P < 0.001). Patients with AUD were hospitalized less (odds ratio, 0.06; 95% confidence interval, 0.12-0.30; compared with AAE). No dermatological emergencies, such as Stevens-Johnson syndrome, were identified. Conclusion Our findings underscore regional differences and support global efforts to reduce non-life-threatening pediatric dermatological presentations to the ED. This study may contribute to the ongoing discourse on effectively managing such presentations in EDs.

Background: s/Aims: Sarcomatoid hepatocellular carcinoma (HCC) is a rare histological subtype of HCC characterized by extremely poor prognosis; however, its molecular characterization has not been elucidated. Methods: In this study, we conducted an integrated multiomics study of whole-exome sequencing, RNA-seq, spatial transcriptome, and immunohistochemical analyses of 28 paired sarcomatoid tumor components and conventional HCC components from 10 patients with sarcomatoid HCC, in order to identify frequently altered genes, infer the tumor subclonal architectures, track the genomic evolution, and delineate the transcriptional characteristics of sarcomatoid HCCs. Results: Our results showed that the sarcomatoid HCCs had poor prognosis. The sarcomatoid tumor components and the conventional HCC components were derived from common ancestors, mostly accessing similar mutational processes. Clonal phylogenies demonstrated branched tumor evolution during sarcomatoid HCC development and progression. TP53 mutation commonly occurred at tumor initiation, whereas ARID2 mutation often occurred later. Transcriptome analyses revealed the epithelial–mesenchymal transition (EMT) and hypoxic phenotype in sarcomatoid tumor components, which were confirmed by immunohistochemical staining. Moreover, we identified ARID2 mutations in 70% (7/10) of patients with sarcomatoid HCC but only 1–5% of patients with non-sarcomatoid HCC. Biofunctional investigations revealed that inactivating mutation of ARID2 contributes to HCC growth and metastasis and induces EMT in a hypoxic microenvironment. Conclusions We offer a comprehensive description of the molecular basis for sarcomatoid HCC, and identify genomic alteration (ARID2 mutation) together with the tumor microenvironment (hypoxic microenvironment), that may contribute to the formation of the sarcomatoid tumor component through EMT, leading to sarcomatoid HCC development and progression.

Anti-tumor traditional Chinese medicine has a long history of clinic application, in which the star molecules have always been the hotspot of modern drug research, but they are limited by the solubility, stability, targeting, bioactivity or toxicity of the monomer components of traditional Chinese medicine anti-tumor star molecules and other pharmacokinetic problems, which hinders the traditional Chinese medicine anti-tumor star molecules for further clinical translation and application. Currently, the nanosystems prepared by supramolecular technologies such as molecular self-assembly and nanomaterial encapsulation have broader application prospects in improving the anti-tumor effect of active components of traditional Chinese medicine, which has attracted extensive attention from scholars at home and abroad. In this paper, we systematically review the research progress in preparation of supramolecular nano-systems from anti-tumor star molecule of traditional Chinese medicine, and summarize the two major categories and ten small classes of carrier-free and carrier-based supramolecular nanosystems and their research cases, and the future development direction is put forward. The purpose of this paper is to provide reference for the research and clinical transformation of using supramolecular technology to improve the clinical application of anti-tumor star molecule of traditional Chinese medicine.

Objective To investigate the feasibility of mimics software in analyzing a new type of complex anterior cervical fixation—anterior transpedicular screw fixation+zero notch internal fixation.Methods From January 2021 to September 2022,50 normal pedestrians who underwent cervical spine CT scanning were selected for C1-C7 segment scanning,including 27 males and 23 females,aged from 25 to 65 years old with an average of(46.0±9.0)years old.The dicom format is exported and engraved into the CD,and use the mimics software to perform 3D reconstruction of each segment.A simulated screw is placed on the image according to the critical value of zero notch screw(head and tail angle 44°,internal angle 29°).The posi-tion of zero notch screw in each segment is observed to determine the feasibility of anterior transpedicular screw fixation plus zero notch internal fixation.Results For the upper zero notch screws the three-dimensional images of the cervical spine across all 50 subjects within the C3-C7 segments demonstrated safe position,wwith no instances of intersection with ATPS.For the lower zero notch screw,in C3-C4 and C4-C5,4 out of 50 subjects are in the safe position in the three-dimensional images of cervical ver-tebrae,and 46 cases could achieve secure screw placement when the maximum caudal angle is(32.3±1.9)° and(36.1±2.2)°,respectively.In C5-C6 and C6-C7 segments,no lower zero notch screws intersected with ATPS,and all screws are in safe posi-tions.Conclusion Lower cervical anterior pedicle screw fixation plus zero notch internal fixation can achieve successful nail placement through the selected entry point and position.
