Spontaneous cutaneous-parotid fistula of the cheek caused by sialolithiasis in a child: a case report.

Introduction: Cheek fistulas of salivary origin in children are very rare, predominantly of congenital or traumatic origin but rarely caused by parotid sialolithiasis given its low prevalence in paediatric populations.

Case Presentation: A 3-year-old child with no history other than substantial left-cheek swelling for 2 months was referred. We identified a cutaneous fistula with seropurulent discharge.

Grafting-from Synthesis of Plant-Polynorbornene Biohybrid Materials.

Plants, essential for food, oxygen, and economic stability, are under threat from human activities, biotic threats, and climate change, requiring rapid technological advancements for protection. Biohybrid systems, merging synthetic macromolecules with biological components, have provided improvement to biological systems in the past, namely, in the biomedical arena, motivating an opportunity to enhance plant well-being. Nevertheless, strategies for plant biohybrid systems remain limited.

Transcultural adaptation and validation of IMPACT-III and IMPACT-III-P in Spanish families: a multicenter study from SEGHNP.

Unlabelled: IMPACT-III and IMPACT-III-P are health-related quality of life (HRQoL) questionnaires for patients with pediatric inflammatory bowel disease (p-IBD) and their parents/caregivers. We aimed to perform a transcultural adaptation and validation for the Spanish context. Translation, back-translation, and evaluation of the questionnaires were performed by an expert committee and 12 p-IBD families.

Burden of lupus activity on health care resources utilization in Buenos Aires, Argentina.

Objective: The aim is to analyze health care resource utilization (HCRU) of patients with lupus (SLE) from a health management organization (HMO) in Buenos Aires, Argentina, compared with matched controls and comparing periods of flare, low disease activity, and remission.

The aim of the study was to evaluate the impact of transition on IBD outcomes. (2) Methods: Multicentre, retrospective and observational study of IBD paediatric patients transferred to an adult IBD unit between 2017-2020.

Pediatric perianal Crohn's disease behavior in the era of biologic therapy.

Aim Of The Study: To describe perianal Crohn's disease behavior and the role of biological therapy in a sample of pediatric patients.

Methods: A retrospective study of pediatric patients with Crohn's disease (CD) treated in our institution from 2017 to 2021, with a minimum follow up period of 6 months, was conducted. Patients were divided whether they had perianal disease (PD) or not.

Polyhydroxy Fullerenes Enhance Antibacterial and Electrocatalytic Activity of Silver Nanoparticles.

Silver nanoparticles (AgNPs) are known and widely used for their antibacterial properties. However, the ever-increasing resistance of microorganisms compels the design of novel nanomaterials which are able to surpass their capabilities. Herein, we synthesized silver nanoparticles using, for the first time, polyhydroxy fullerene (PHF) as a reducing and capping agent, through a one-pot synthesis method.

Clinical Features of ANCA-Associated Vasculitis in African American Patients in the United States: A Single-Center Medical Records Review Study.

Background/purpose: The aim of this study was to compare the clinical features at presentation of ANCA-associated vasculitis (AAV) between African American (AA) and White patients.

Methods: This is a chart review of cases between January 2003 and December 2018. African American patients with AAV were identified and matched in a 1:2 ratio with White comparators based on the year of diagnosis (±4 years).

Endoscopic stapes surgery outcomes and complication rates: a systematic review.

Objective: These days, the gold standard procedure for otosclerosis treatment is stapes surgery. The endoscopic approach of the procedure is gaining popularity as endoscopic ear surgery develops across the globe. The main objective of this study is to gather and compile well-documented and reliable data regarding surgical outcomes for the endoscopic approach to stapes surgery up to this date.

High frequency and prognostic value of L265P mutation in diffuse large B-cell lymphoma with R-CHOP treatment.

The aim of this study was to analyze the prevalence and prognostic value of myeloid differentiation factor 88 () L265P in diffuse large B-cell lymphoma (DLBCL) patients treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). We assessed the L265P mutation using an allele-specific semi-nested polymerase chain reaction method in 53 DLBCL patients treated with R-CHOP. The L265P mutation was detected in 16 of 53 DLBCL (30.

Molecular and pathobiological characterization of 61 Potato mop-top virus full-length cDNAs reveals great variability of the virus in the centre of potato domestication, novel genotypes and evidence for recombination.

The evolutionary divergence of Potato mop-top virus (PMTV), a tri-partite, single-stranded RNA virus, is exceptionally low, based on the analysis of sequences obtained from isolates from Europe, Asia and North America. In general, RNA viruses exist as dynamic populations of closely related and recombinant genomes that are subjected to continuous genetic variation. The reason behind the low genetic variation of PMTV remains unclear.

[Results in the surgical treatment of giant acoustic neuromas].

Introduction And Objectives: To compare the results obtained in the resection of 21 giant vestibular schwannomas via retrosigmoid (RS) and combined retrosigmoid/translabyrinthine (RS/TL) approaches with respect to intra- and postoperative complications, facial nerve preservation and postsurgical sequelae.

Methods: This was a retrospective study of 21 patients who underwent a resection of a giant vestibular neuroma according to the Tos & Thomsen Scale (greater than or equal to 4 centimetres) in a tertiary care centre in the period between 2000 and 2008. We present the most significant characteristics of the series studied and the analysis of the advantages and inconveniences of each approach.

In vivo and in vitro effects of RAD001 on bladder cancer.

First description of Cryptosporidium bovis in Japan and diagnosis and genotyping of Cryptosporidium spp. in diarrheic pre-weaned calves in Hokkaido.

Eighty fecal samples from pre-weaned calves with diarrhea were collected in the Tokachi area in Northern Japan to investigate the prevalence of Cryptosporidium species in such animals. Oocysts from fecal samples collected from each animal were concentrated using sucrose gradient centrifugation. Genomic DNA was extracted from each sample and processed by nested PCR to amplify the partial SSU rRNA gene of Cryptosporidium.
