Dysmenorrhea among 12-year-old teenagers from different socioeconomic backgrounds.

Background: The age of menarche has been gradually declining since the end of the 20th century. Few studies have been carried out about dysmenorrhea in Europe and they mainly included girls over the age of 15 years.

Methods: We conducted an observational study among sixth-grade schoolgirls (usually 11-12 years) during the 2020 academic year in 72 randomly selected public schools in a French region (approval number #20.

Emergence of New Concepts in Skin Physiopathology through the Use of in vitro Human Skin Explants Models.

Background: This review summarizes uses and new applications for dermatological research of in vitro culture models of human skin explants (HSEs). In the last decade, many innovations have appeared in the literature and an exponential number of studies have been recorded in various fields of application such as process culture engineering, stem cell extractions methodology, or cell-to-cell interaction studies under physiological and pathological conditions, wound-healing, and inflammation. Most studies also concerned pharmacology, cosmetology, and photobiology.

Relationships between soil ecosystem services in temperate annual field crops: A systematic review.

Agricultural soils provide multiple ecosystem services (ES) that can replace chemical inputs to support agricultural production. However, most arable cropping systems are managed with little concern for preserving ecological functions, which could reduce their ability to provide these ES. An increasing number of studies assess ES from agroecosystems, but analysis of multiple ES distinguishing relationships that may exist between them and between these ES and their drivers is lacking.

Complication rates of proximal hypospadias: meta-analyses of four surgical repairs.

Introduction: Proximal hypospadias surgery is impacted by a high complication rate. The goal of this work was to assess the overall composite complication rate, fistula rate and stenosis rate following proximal hypospadias surgery realized according to onlay urethroplasty, Duckett, Koyanagi and Bracka techniques.

Methods: The databases MEDLINE, EMBASE, SCOPUS, Cochrane Library, the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials (CENTRAL) and Sciencedirect were searched.

Different Fecal Microbiota in Hirschsprung's Patients With and Without Associated Enterocolitis.

Background And Objectives: Patients with Hirschsprung's disease are at risk of developing Hirschsprung-associated enterocolitis, especially in the first 2 years of life. The pathophysiology of this inflammatory disease remains unclear, and intestinal dysbiosis has been proposed in the last decade. The primary objective of this study was to evaluate in a large cohort if Hirschsprung-associated enterocolitis was associated with alterations of fecal bacterial composition compared with HD without enterocolitis in different age groups.

Pulvinar and pubic cartilage measurements to refine universal ultrasound screening for developmental dysplasia of the hip: Data from 1896 infant hips.

Purpose: Screening modalities for Developmental Dysplasia of the Hip (DDH) and indications for treatment of mild forms remain controversial. Ultrasound (US) measurement of the pubofemoral distance (PFD > 6 mm, composed of the pubic cartilage and the pulvinar) can avoid late diagnoses of DDH. A thick pubic cartilage may nevertheless lead to false positives.

Simulated patient and role play methodologies for communication skills and empathy training of undergraduate medical students.

Background: Verbal and non-verbal communication, as well as empathy are central to patient-doctor interactions and have been associated with patients' satisfaction. Non-verbal communication tends to override verbal messages. The aim of this study was to analyze how medical students use verbal and non-verbal communication using two different educational approaches, student role play (SRP) and actor simulated patient (ASP), and whether the non-verbal behaviour is different in the two different poses.

Using a multivariate regression tree to analyze trade-offs between ecosystem services: Application to the main cropping area in France.

Analysis of trade-offs and synergies between ecosystem services (ES) and their underlying drivers is a main issue in ES research. The analysis is complex and requires innovative analytical approaches. To address this complexity, we used an original approach that combines a multivariate regression tree (MRT), data analysis, and spatial mapping.

Professional practice assessment: establishment of an institutional procedure to treat blunt abdominal trauma in emergency pediatric department.

Objective: The clinical process for the diagnosis of intra-abdominal lesion due to blunt abdominal trauma in children is not consistent. The goal of the present study was to assess the efficiency of our institutional procedure to manage hemodynamically stable pediatric patients with benign abdominal trauma and to select patients who need a radiological examination in an emergency pediatric department.

Material And Methods: This was a prospective cohort study from June 2008 to June 2010 in a pediatric emergency department.

Renal artery embolization in a child with delayed hemodynamic instability from penetrating knife wound.

Penetrating laceration injury in the pediatric population may present as an acute or delayed life-threatening injury. Although emergent intra-arterial embolization is commonly utilized in adults, few cases have been reported for children. Surgical treatment for severe renal laceration injuries may require complete nephrectomy; an unfortunate outcome for a pediatric patient if a renal-preserving alternative is feasible.

Autoimmune Pancreatitis and Ulcerative Rectocolitis in an Adolescent.

Autoimmune pancreatitis (AIP) is rare in teenagers and difficult to diagnose. There are no clear and established diagnostic criteria in the pediatric population to distinguish subtype 1 and subtype 2. Here, we report the case of a 16-year-old white French teenager admitted to the pediatric emergency service with more than 1 year's history of pain originating from the epigastric and the right hypochondriac regions, with bloody diarrhea.

Influence of human impacts on Albeluvisol analysed by X-ray microfluorescence: relative evolution of the transforming front at the tongue scale.

In this paper we studied the nature and hierarchy of the processes responsible for soil evolution as a function of land use (forest and culture). Albeluvisols were chosen as a pedological model for this study. Iron, manganese, calcium, potassium and trace elements were used as indicators of the soil processes.

[Prolactin adenoma developed during puberty. Diagnosis and long-term course. 9 cases].

Nine patients (2 boys, 7 girls) with prolactinomas diagnosed at puberty were followed for 2 to 20 years. The presenting signs were sexual infantilism (n = 2), amenorrhea-galactorrhea (n = 6) and hypogonadism (n = 1). Growth retardation was also present in 3 cases.
