[Differential diagnosis of strokes, the traps to avoid]. / Diagnostics différentiels d'AVC, les pièges à éviter.

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. However, in no case must this delay the urgent treatment of the patient suspected of having a stroke.

[Pyoderma gangrenosum and hemopathies in older patients]. / Pyoderma gangrenosum et hémopathies chez la personne âgée.

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. The association with inflammatory or hematologic conditions is frequent, especially in older patients. The hematologic diseases the most frequently associated with PG are myelodysplastic syndrome, followed by monoclonal gammopathy of undetermined significance. Because of the strong impact of its treatment, recognition of PG is crucial. The treatment is based on first-line corticosteroids and topical or systemic immunosuppressive drugs and most often leads to a favourable outcome. The management of an acute hematologic disease would further improve the prognosis of PG. The singularity of geriatric patients encourages to thoroughly balance the risks and benefits of the recommended drugs and to consider associated non-drug measures. Here, we propose a review of the scientific literature about the association between PG and hematologic diseases, with a special focus on older patients, accompanied by the report of two cases in geriatric ward.

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. We included all consecutive patients aged 70 years and older who were hospitalized with confirmed COVID-19 in these wards. Propensity score and multivariate analyses were used. RESULTS: Of the 1 579 patients included (535 received corticosteroids), the median age was 86 (interquartile range 81-91) years, 56% of patients were female, the median Charlson Comorbidity Index (CCI) was 2.6 (interquartile range 1-4), and 64% of patients were frail (Clinical Frailty Score 5-9). The propensity score analysis paired 984 patients (492 with and without corticosteroids). The in-hospital mortality was 32.3% in the matched cohort. On multivariate analysis, the probability of in-hospital mortality was increased with corticosteroid use (odds ratio [OR] = 2.61 [95% confidence interval (CI) 1.63-4.20]). Other factors associated with in-hospital mortality were age (OR = 1.04 [1.01-1.07], CCI (OR = 1.18 [1.07-1.29], activities of daily living (OR = 0.85 [0.75-0.95], oxygen saturation < 90% on room air (OR = 2.15 [1.45-3.17], C-reactive protein level (OR = 2.06 [1.69-2.51], and lowest lymphocyte count (OR = 0.49 [0.38-0.63]). Among the 535 patients who received corticosteroids, 68.3% had at least one corticosteroid side effect, including delirium (32.9%), secondary infections (32.7%), and decompensated diabetes (14.4%). CONCLUSIONS: In this multicentric matched-cohort study of geriatric patients hospitalized for COVID-19, the use of corticosteroids was significantly associated with in-hospital mortality.

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. METHODS: All patients consecutively admitted after a HF surgery in a geriatric perioperative unit were included in this cross-sectional study. FI was systematically assessed by a digital rectal exam at admission and according to clinical suspicion during the hospital stay. The dependent variable was POUR, systematically screened according to the department protocol and defined as a bladder volume>400ml requiring catheterization. The association between FI and POUR was assessed by multivariable analysis. RESULTS: A total of 256 patients were included (mean [SD] age 86 [6] years), (76% women): 108 (42%) presented FI and 63 (25%) POUR. The frequency of FI was higher with than without POUR (73% vs. 32%, P<0.001). On multivariable analysis, after adjusting for age, sex, Cumulative Illness Rating Scale score and anticholinergic load, FI was the only factor independently associated with POUR (odds ratio 4.78) [95% confidence interval 2.44-9.71], P<0.001. CONCLUSIONS: FI was the only independent factor associated with POUR after HF surgery in older adults. Further studies are needed to optimize perioperative geriatric care including FI and POUR assessment and management.

Clinical Characteristics and Outcomes of 821 Older Patients With SARS-Cov-2 Infection Admitted to Acute Care Geriatric Wards.

BACKGROUND: There is limited information describing the characteristics and outcomes of hospitalized older patients with confirmed coronavirus disease 2019 (COVID-19). METHOD: We conducted a multicentric retrospective cohort study in 13 acute COVID-19 geriatric wards, from March 13 to April 15, 2020, in Paris area. All consecutive patients aged 70 years and older, with confirmed COVID-19, were enrolled. RESULTS: Of the 821 patients included in the study, the mean (SD) age was 86 (7) years; 58% were female; 85% had ≥2 comorbidities; 29% lived in an institution; and the median [interquartile range] Activities of Daily Living scale (ADL) score was 4 [2-6]. The most common symptoms at COVID-19 onset were asthenia (63%), fever (55%), dyspnea (45%), dry cough (45%), and delirium (25%). The in-hospital mortality was 31% (95% confidence interval [CI] 27-33). On multivariate analysis, at COVID-19 onset, the probability of in-hospital mortality was increased with male gender (odds ratio [OR] 1.85; 95% CI 1.30-2.63), ADL score <4 (OR 1.84; 95% CI 1.25-2.70), asthenia (OR 1.59; 95% CI 1.08-2.32), quick Sequential Organ Failure Assessment score ≥2 (OR 2.63; 95% CI 1.64-4.22), and specific COVID-19 anomalies on chest computerized tomography (OR 2.60; 95% CI 1.07-6.46). CONCLUSIONS: This study provides new information about older patients with COVID-19 who are hospitalized. A quick bedside evaluation at admission of sex, functional status, systolic arterial pressure, consciousness, respiratory rate, and asthenia can identify older patients at risk of unfavorable outcomes.
