Abstract
Parapharyngeal infections carry a significant risk of extensive suppuration and airway compromise. We report the case of a patient presenting with a right paranasopharyngeal abscess, featuring atypical symptoms that made diagnosis particularly challenging. Complications included evidence of right vocal cord paralysis, likely secondary to involvement of the vagus nerve. Notably, this paralysis occurred in isolation, without involvement of cranial nerves IX or XI, which would be expected from jugular foramen encroachment. Imaging demonstrated the presence of a collection extending towards the skull base, which was drained using a transnasal endoscopic approach, avoiding the use of external incisions. Tissue biopsies from the abscess wall suggest that the underlying aetiology was minor salivary gland sialadenitis, which has not been previously reported in the literature.

Abstract
Major operations on the head and neck that involve microvascular reconstruction and a tracheostomy are prolonged procedures with considerable postoperative risk. Postoperative pulmonary complications are common because of mechanical ventilation, immobility, and inadequate humidification. High-flow heated oxygen therapy (HFOT) may overcome some of these issues, but we know of no published studies to support its use. The aim of this single-site randomised controlled trial therefore was to explore its feasibility and safety in these patients. Twenty patients were randomised to have HFOT (10 patients) or standard oxygen therapy (10 patients). HFOT was used from cessation of mechanical ventilation until decannulation of the tracheostomy. The primary outcome was feasibility. The secondary outcome measures explored the incidence of postoperative pulmonary complications, achievement of milestones of weaning from the tracheostomy, and hospital length of stay. A total of 21 patients were consecutively recruited and all provided informed consent. One who did not require a tracheostomy was later excluded. All patients initially had the intervention as planned, and one was electively changed to the control group because of discomfort caused by the high-flow oxygen. There were no adverse events or safety concerns in either group. Secondary outcomes showed a reduction in the incidence of pulmonary complications in the HFOT group. The use of HFOT is safe and feasible in patients who have microvascular reconstruction of the head and neck and a tracheostomy.

Abstract
BACKGROUND Several new treatment strategies have emerged in the treatment of small renal masses (<4 cm in diameter). Active surveillance and ablative techniques have been introduced but it remains unclear which patients will benefit the most from these new treatment options. A surgical approach remains standard of care. In recent decades, radical nephrectomy has been replaced by nephron-sparing surgery for the management of small renal masses. RESULTS In addition to the open partial nephrectomy, which is considered the standard approach, the number of surgeries performed using minimally invasive techniques is increasing. Recent data show that there might be some benefits such as less blood loss. The disadvantages shown by laparoscopic partial nephrectomy such as prolonged warm ischemia, longer operation times, and postoperative renal impairment might be negligible for the robotic approach. Therefore, current guidelines allow these approaches in addition to open partial nephrectomy if sufficient surgical expertise is given.

Abstract
Complex landscapes including semi-natural habitats are expected to favour natural enemies thereby enhancing natural pest biocontrol in crops. However, when considering a large number of situations, the response of natural biocontrol to landscape properties is globally inconsistent, a possible explanation being that local agricultural practices counteract landscape effects. In this study, along a crossed gradient of pesticide use intensity and landscape simplification, we analysed the interactive effects of landscape characteristics and local pesticide use intensity on natural biocontrol. During 3 years, using a set of sentinel prey (weed seeds, aphids and Lepidoptera eggs), biocontrol was estimated in 80 commercial fields located in four contrasted regions in France. For all types of prey excepted weed seeds, the predation rate was influenced by interactions between landscape characteristics and local pesticide use intensity. Proportion of meadow and length of interface between woods and crops had a positive effect on biocontrol of aphids where local pesticide use intensity was low but had a negative effect elsewhere. Moreover, the landscape proportion of suitable habitats for crop pests decreased the predation of sentinel prey, irrespectively of the local pesticide use intensity for weed seeds, but only in fields with low pesticide use for Lepidoptera eggs. These results show that high local pesticide use can counteract the positive expected effects of semi-natural habitats, but also that the necessary pesticide use reduction should be associated with semi-natural habitat enhancement to guarantee an effective natural biocontrol.

Abstract
INTRODUCTION Pyostomatitis vegetan (PV) is often associated with chronic inflammatory bowel disease (IBD). OBSERVATION Two cases of PV are reported. Case number 1 is a 66-year-old patient treated with infliximab for ulcerative colitis (UC). He presented himself with rapidly progressing crusty, whitish, ulcerated lesions on his lips. Diagnosis of PV was made after biopsy. Regression of oral lesions was favourable with local application of dermocorticoids while continuing infliximab treatment. Case number 2 is a 20-year-old patient treated with infliximab for Crohn's disease (CD). She had cheilitis and angular cheilitis. Diagnosis of PV was made after biopsy. The evolution was favourable after treating with topical dermocorticoids. DISCUSSION PV is associated in 75% of the cases with IBD. The digestive check-up is systematic. Diagnostic delay is often noted. Topical dermocorticoids are the first line of therapy.

Abstract
The two SIBLING (Small Integrin Binding Ligand N-linked Glycoproteins), bone sialoprotein (BSP) and osteopontin (OPN) are expressed in osteoblasts and osteoclasts. In mature BSP knockout (KO, -/-) mice, both bone formation and resorption as well as mineralization are impaired. OPN-/- mice display impaired resorption, and OPN is described as an inhibitor of mineralization. However, OPN is overexpressed in BSP-/- mice, complicating the understanding of their phenotype. We have generated and characterized mice with a double KO (DKO) of OPN and BSP, to try and unravel their respective contributions. Despite the absence of OPN, DKO bones are still hypomineralized. The SIBLING, matrix extracellular phosphoglycoprotein with ASARM motif (MEPE) is highly overexpressed in both BSP-/- and DKO and may impair mineralization through liberation of its ASARM (Acidic Serine-Aspartate Rich MEPE associated) peptides. DKO mice also display evidence of active formation of trabecular, secondary bone as well as primary bone in the marrow-ablation repair model. A higher number of osteoclasts form in DKO marrow cultures, with higher resorption activity, and DKO long bones display a localized and conspicuous cortical macroporosity. High bone formation and resorption parameters, and high cortical porosity in DKO mice suggest an active bone modeling/remodeling, in the absence of two key regulators of bone cell performance. This first double KO of SIBLING proteins thus results in a singular, non-trivial phenotype leading to reconsider the interpretation of each single KO, concerning in particular matrix mineralization and the regulation of bone cell activity.

Abstract
Abstract
Inflammatory breast cancer (IBC) is the most lethal form of breast cancer that accounts for about 10% of breast cancer mortality annually in US. Poor prognosis is largely due to the high propensity of IBC tumors to develop distant metastasis that occurs directly from the gland epithelium and through lymphatic invasion in which dermal lymphatics are filled with tumor emboli. Owing to the complex metastatic process, the molecular basis of IBC aggressiveness is poorly understood, and no specific therapeutic target has been identified. Despite the lack of estrogen receptor α (ERα) in the majority of IBC tumors, estrogen may still play a role in these cancers through pathways that involve ERβ. Our tissue staining reveals expression of ERβ in more than 50% of IBCs that is reproduced in IBC cell lines. Furthermore, analysis of IBC datasets indicates correlation of receptor expression with good prognosis. We studied this association in preclinical models of IBC by knocking out ERβ in IBC cells. This promotes migration and invasion through cytoskeleton remodeling whereas re-expression of the receptor in knockout cells restores the cytoskeletal structure and migration to the levels of control cells. Consistent with increased migration, deletion of ERβ activates large gene networks of cell de-differentiation and cytokine synthesis that trigger tumor microenvironment responses to promote the motile phenotype of IBC cells. In contrast, ligands that activate the receptor inhibit signaling that contributes to metastasis in IBC. Analysis of an orthotopic xenograft model shows that IBC tumors lacking ERβ have higher propensity for metastasis compared with the ERβ-proficient tumors supporting the anti-metastatic activity of the receptor. Our findings point towards a role of ERβ in preventing distant metastases by inhibiting dissemination of IBC cells and maintaining the integrity of emboli. This function combined with distinct expression indicates the potential of ERβ to represent a unique prognostic marker and therapeutic target that can be utilized to repress IBC metastasis and eliminate its associated mortality.
