Posterior staphyloma (PS) is a hallmark of pathological myopia, corresponding to a circumscribed outpouching of the eyeball with choroidal thinning and inward scleral deformation at its edges. Its pathogenesis is still unclear, thus constituting a research priority as the prevalence of myopia is increasing worldwide. Recently, it has been suggested that the optic nerve sheaths or oblique muscles are potential promoters of PS through the traction or compression effect that they apply to the eye wall.

We here determine prospectively the timing and magnitude of methylprednisolone (mPDN)-induced lymphocytosis and study the effects of concomitant propranolol administration on lymphocyte count (Ly).
Methods: Ly was measured before and 24 to 72hours after initiating mPDN treatment in 20 patients with immune-mediated inflammatory disorders (IMID).
Background: This study evaluated the safety and efficacy of salvage endoscopic submucosal dissection (ESD) for Barrett's neoplasia recurrence after radiofrequency ablation (RFA).
Methods: Data from patients at 16 centers were collected for a multicenter retrospective study. Patients who underwent at least one RFA treatment for Barrett's esophagus and thereafter underwent further esophageal ESD for neoplasia recurrence were included.
Introduction: The incidence of intramedullary spinal cord tumors ranges from 2 to 4% of all central nervous system tumors. Only 6-8% are astrocytomas. The gold standard to diagnose a spinal cord tumor is the spinal cord MRI .

Background: Chronic spontaneous urticaria (CSU) is a chronic inflammatory skin disease where activation of endothelial cells (ECs) at sites of skin lesions leads to increased blood flow, leakage of fluid into the skin, cellular infiltration, and vascular remodeling. To understand the disease duration and the sometimes vague systemic symptoms accompanying flares, the objective of this study was to examine if CSU comes with systemic vascular changes at the microcirculatory level.
Methods: We investigated CSU patients (n = 49) and healthy controls (HCs, n = 44) for microcirculatory differences by nailfold videocapillaroscopy (NVC) and for blood levels of the soluble EC biomarkers serum vascular endothelial growth factor (VEGF), soluble E-selectin, and stem cell factor (SCF).
Purpose: Myopic eyes combining gamma peripapillary atrophy and peripapillary staphyloma were sorted according to the presence of intrachoroidal cavitation (PICCs) or its absence (combinations). Visual field defects (VFDs) and factors discriminating these groups were analyzed.
Methods: These groups were sorted by optical coherence tomography.
Background: Chronic urticaria (CSU) is a chronic inflammatory mast cell-driven disorder of which reliable clinical data in Belgium are lacking. This study focusses on clinical characteristics of CSU patients presenting at an urban Immunology-Allergology department.
Methods: Outpatients with CSU were included from 2018 to 2021.
Importance: A potential relationship between meningioma and breast cancer was suggested 70 years ago. However, to date, no conclusive evidence is available on this topic.
Objective: To provide a comprehensive review of the literature on the association of meningioma with breast cancer, supported by a meta-analysis.
Purpose: Embolization of arteriovenous malformations (AVMs) before radiosurgery has been reported to negatively impact the obliteration rate. This study aims to assess treatment outcomes in a series of 190 patients treated by Gamma Knife radiosurgery (GKRS) for previously embolized AVMs.
Methods: The institutional database of AVMs was retrospectively reviewed between January 2004 and March 2018.
Various surgical methods to prevent postoperative cerebrospinal fluid (CSF) leaks during transsphenoidal surgery have been reported. However, comparative studies are scarce. We aimed to compare the efficacy of a fibrin-coated collagen fleece (TachoSil) versus a dural sealant (DuraSeal) to prevent postoperative CSF leakage.

Objective: To explore the evolution and geographic distribution of common cutaneous infestations and arthropod bites through an analysis of Google Trends.
Background: Real-life data on topical treatments in daily practice in patients with moderate acne are poorly characterized.
Objective: To investigate the drug survival of topical treatments administered to patients with moderate acne in a daily practice.
Methods: Survival analysis was performed on subjects (Belgian university hospital and private practice outpatient dermatology patients) with moderate acne who received topical therapies according to the current published guidelines.
Demodex folliculorum and brevis are commensal mites that live in low densities in human pilosebaceous follicles as part of the normal adult microbiota, but that give rise to demodicosis and, possibly, rosacea, when they proliferate excessively. This proliferation is favored by various factors, including age, marked immunosuppression, sebaceous gland hyperplasia, and hypervascularization-related factors. To study possible factors influencing mite proliferation, we explored the effects of different variables on Demodex densities (Dd) in a retrospective study of two groups of subjects selected on the basis of their clinical diagnosis: Demodex+, consisting of subjects with demodicosis or with centro-facial papulopustules suggesting rosacea (n = 844, mean Dd 263.

Methods: In a prospective observational study, we enrolled all consecutive patients ≥16 years of age with a presumptive diagnosis of scabies and all patients ≥16 years of age with a diffuse itchy dermatosis lasting for more than 1 week.
Background: Patients with rosacea and demodicosis have high facial skin Demodex densities (Dds), which decrease with benzyl benzoate (BB) treatment.
Objectives: To evaluate the impact of topical BB (+crotamiton) treatment on Dds and clinical symptoms during prolonged follow-up and to compare low (12% once daily) and high (12% twice daily or 20-24% once daily) BB dose regimens.
Methods: This retrospective study included 344 patients (103 rosacea, 241 demodicosis) observed for 7.
Primary microcephaly (PM) is characterized by a small head since birth and is vastly heterogeneous both genetically and phenotypically. While most cases are monogenic, genetic interactions between Aspm and Wdr62 have recently been described in a mouse model of PM. Here, we used two complementary, holistic in vivo approaches: high throughput DNA sequencing of multiple PM genes in human patients with PM, and genome-edited zebrafish modeling for the digenic inheritance of PM.

However, recent studies have challenged the requirement of EMT for metastasis. Here, we assessed in different models of primary skin squamous cell carcinomas (SCCs) whether EMT is associated with metastasis.

Background: Patients with rosacea or demodicosis have high facial skin Demodex densities (Dds). Topical ivermectin, benzyl benzoate (BB) and crotamiton have been shown to decrease Dds in vivo, but there are few data on the clinical and acaricidal effects of BB among patients with rosacea.
Objective: To evaluate the impact of topical BB (+crotamiton) treatment on Dds and clinical symptoms of rosacea and demodicosis, and compare three BB treatment regimens.
Sex differences are observed in the evolution of numerous inflammatory conditions. Women exhibit better clinical courses compared to men in acute inflammatory processes, yet worse prognosis in several chronic inflammatory diseases. Inflammatory markers are significantly different between prepubertal boys and girls, whose sex steroid levels are very low, suggesting genetics play a role.
