[Pyoderma gangrenosum and hemopathies in older patients].

Pyoderma gangrenosum (PG) belongs to neutrophilic dermatoses. PG can have different clinical presentations (ulcerated, bullous, pustular), is often painful, and preferentially affects the lower limbs. The diagnosis can be challenging, and a cutaneous biopsy is often necessary, which shows an aseptic cutaneous infiltrate of neutrophils.

Corticosteroid Therapy in COVID-19 Associated With In-hospital Mortality in Geriatric Patients: A Propensity Matched Cohort Study.

Background: Few data are available on the prognosis of older patients who received corticosteroids for COVID-19. We aimed to compare the in-hospital mortality of geriatric patients hospitalized for COVID-19 who received corticosteroids or not.

Methods: We conducted a multicentric retrospective cohort study in 15 acute COVID-19 geriatric wards in the Paris area from March to April 2020 and November 2020 to May 2021.

Fecal impaction is associated with postoperative urinary retention after hip fracture surgery.

Background: Postoperative urinary retention (POUR) is a common hip fracture (HF) complication. Although fecal impaction (FI) is one of the oft-cited causes of POUR in clinical practice, evidence regarding this association is scarce.

Objective: The aim of this study was to determine whether FI was associated with POUR after HF surgery in older patients.

[Differential diagnosis of strokes, the traps to avoid].

Strokes are a significant issue in geriatric medicine as more than half occur in patients over the age of 75. However, not all the symptoms of a focal neurological deficit in the elderly are indicative of a stroke. There are a number of differential diagnoses and only a detailed examination of the patient can enable an accurate diagnosis to be established.

Comparing physical activity questionnaires for youth: seasonal vs annual format.

Background: In large cohort studies of older children, self-report is the only practical way to assess physical activity. Assessing usual activity over the entire year is desirable, but children and adolescents may overestimate activities with high seasonal variability. Use of questionnaires in which individuals report each activity by season may improve accuracy.

Association of adolescent cigar use with other high-risk behaviors.

Objectives: To describe the association of cigar use with use of cigarettes, smokeless tobacco, and alcohol among adolescents; and to examine the association of self-esteem, physical activity, and use of tobacco promotional items with cigar use.

Methods: A cross-sectional study of 7104 girls and 5499 boys 10 to 15 years of age in 1997. Data were collected from self-report questionnaires.

Reproducibility and validity of maternal recall of pregnancy-related events.

We assessed the reproducibility and validity of a questionnaire that asks mothers to recall pregnancy-related events from thirty or more years ago. Among 146 women who completed the questionnaire twice, responses were highly reproducible for pre-pregnancy height and weight (r = 0.95), pregnancy complications (r = 0.

Weight concerns, weight control behaviors, and smoking initiation.

Objective: To examine the cross-sectional relationships between weight concerns, weight control behaviors, and initiation of tobacco use among youths.

Study Design: Smoking status, weight concerns, and weight control behaviors were assessed in a cross-sectional sample of 16 862 children, 9 to 14 years of age, in 1996. Logistic regression was used to examine the relationship between weight concerns, weight control behaviors, and early stages of smoking initiation (precontemplation, contemplation, and experimentation).
