Background: Erythrodermic psoriasis (EP) is a severe and rare variant of psoriasis. Clinical features include scaling and erythema affecting more than 75% of body surface area, associated with systemic symptoms such as lymphadenopathy, arthralgia, fever, fatigue, dehydration, serum electrolyte disturbances, and tachycardia, making this condition a potentially life-threatening disease. Differential diagnosis can be challenging, encompasses atopic dermatitis, cutaneous adverse drug reaction, and advanced cutaneous lymphoma.

Background: Pompe disease, also known as glycogenosis type II or acid maltase deficiency, is an autosomal recessive disease caused by a deficiency of alpha-glucosidase. The severity depends mainly on the type of mutation, which in turn determines early or late onset; therapy modifies the outcome but does not alter the severity of the disease at presentation.

Case Presentation: We present a case report of a male infant, inborn and delivered at a gestational age of 39 weeks.

: Lung cancer is the leading cause of cancer-related deaths worldwide and mediastinal lymph node involvement is an important negative prognostic factor. Nevertheless, the involvement of a single mediastinal nodal zone has been reported to have favorable outcomes. This study aims to assess whether the prognosis of non-small-cell lung cancer (NSCLC) with single-zone lymph node involvement varies by the affected lymph node zone.

Thymic epithelial tumors (TETs) are a heterogeneous group of rare tumors that arise from thymic epithelial cells in the anterior mediastinum. They can be divided into three different histological subtypes: thymomas, thymic carcinomas (TC), and neuroendocrine carcinomas (TNET). TCs and TNETs are rarer but more aggressive entities with frequent distant metastasis.

Objectives: Smoking is a modifiable risk factor for lung resections but to what extent preoperative smoking cessation reduces that risk remains unclear. The study hypothesis was that the potential benefit of smoking cessation can be assessed by measuring the risk difference between active and former smokers in a large cohort of patients.

Methods: Data were extracted from the French Society of Thoracic and Cardiovascular Surgeons (Société Française de Chirurgie Thoracique et Cardiovasculaire) database.

The possibility of modulating the treatment regimen regarding dose reduction (de-escalation) or dose augmentation (escalation) in psoriasis biological treatment has been of increasing interest. De-escalation strategies include reducing the single therapeutic dose, the mg/kg ratio or the number of injections, or dose-spacing (D-S), that is, extending the interval between administrations. Data regarding dose de-escalation, in particular D-S, on IL-23, are lacking to date.

Acute infectious diarrhea (AID) represents an important clinical entity both regarding morbidity and mortality rates, even in industrialized countries, and it leads to one of the major public health burdens, among gastroenterological diseases, with significant healthcare costs. Oral rehydration solution is the cornerstone of the therapy, but despite its proven efficacy in avoiding dehydration, it is still underused as it does not reduce the duration of diarrhea; hence, it is perceived as ineffective by caregivers. In this narrative review, we collected literature regarding the use of racecadotril, deeply discussing its role in the treatment of AID in both adults and children.

Psoriasis (PSO) involves about 1-3% of the population, and around 75% of women develop PSO before the age of 40. Official guidelines on the treatment of woman with anti-IL17 and anti-IL23 during this potential childbearing time are not currently available. To investigate the effectiveness and safety of biologic treatments in women of childbearing age.

Article Synopsis
  • Subglottic cysts (SGCs) are rare but serious causes of breathing problems in premature infants, often linked to factors like male gender and invasive ventilation.
  • A case study details a premature male infant born at 25 weeks who developed SGCs after extended intubation, leading to severe airway obstruction treated by tracheotomy and cyst removal.
  • The findings highlight the importance of considering SGCs in similarly affected preterm infants, emphasizing the need for early diagnosis and intervention to improve outcomes.

Marine space is three dimensional, the turnover of life forms is rapid, defining a fourth dimension: time. The definition of ecologically significant spatial units calls for the spatio-temporal framing of significant ecological connections in terms of extra-specific (biogeochemical cycles), intra-specific (life cycles), and inter-specific (food webs) fluxes. The oceanic volume can be split in sub-systems that can be further divided into smaller sub-units where ecosystem processes are highly integrated.

Thymus is considered a non-functional remnant in adults, but some evidence suggest that it may harbor residual activity. Lung cancer patients represent the ideal model to study thymic residual activity, as their thymus can be easily harvested during surgery. This study was designed to confirm the presence of residual thymic activity both in adult mice (step 1) and in humans (step 2).

As β-diversity can be seen as a proxy of ecological connections among species assemblages, modeling the decay of similarity in species composition at increasing distance may help elucidate spatial patterns of connectivity and local- to large-scale processes driving community assembly within a marine region. This, in turn, may provide invaluable information for setting ecologically coherent networks of marine protected areas (MPAs) in which protected communities are potentially interrelated and can mutually sustain against environmental perturbations. However, field studies investigating changes in β-diversity patterns at a range of spatial scales and in relation to disturbance are scant, limiting our understanding of how spatial ecological connections among marine communities may affect their recovery dynamics.

Pathogenic variants in are typically associated with a clinical condition called "capillary malformation-arteriovenous malformation" (CM-AVM) syndrome, an autosomal dominant genetic disease characterized by a broad phenotypic variability, even within families. In CM-AVM syndrome, multifocal capillary and arteriovenous malformations are mainly localized in the central nervous system, spine and skin. Although CM-AVM syndrome has been widely described in the literature, only 21 cases with prenatal onset of clinical features have been reported thus far.
