Spontaneous retropharyngeal abscess presenting as delirium in a frail older woman: a case-based review.

INTRODUCTION: Retropharyngeal abscess (RPA) is an uncommon infection in older people, which usually presents with localized upper airway symptoms. CASE PRESENTATION: We present a case of RPA in a 69-year-old frail woman with co-morbidities, who presented atypically with delirium. She initially complained of general symptoms of malaise, body aches and general decline. Her symptoms progressed to hypoactive delirium before she started to localize her complaints to the upper airway. The delirium presentation of RPA is not commonly reported in the literature. Co-morbidities and frailty are likely to be the underlying risk factors for delirium presentation in this case. Most of the RPA cases reported in older people in the literature presented typically with localized symptoms, however these cases had lower burden of morbidities and reported no frailty. In our case report, poor mouth hygiene and dental caries were thought to be the source of infection. Early intervention with antibiotic treatment for total of four weeks resulted in a full recovery. CONCLUSION: RPA may present with delirium in older people with frailty and co-morbidities. Poor oral hygiene and dental caries, if left untreated, may progress into serious deep space neck infection.

Anemia: An Independent Predictor Of Adverse Outcomes In Older Patients With Atrial Fibrillation.

Both anemia and atrial fibrillation are common in older people and their prevalence is age dependent which increases as population ages. Anemia, especially acute onset, predisposes to new onset atrial fibrillation which is likely to be mediated through inducing heart failure first and this predisposition seems to be potentiated by the presence of renal impairment. Anemia adds to the comorbidity burden of patients with atrial fibrillation and independently increases the risks of adverse outcomes such as increased hospitalization, mortality, bleeding and thromboembolic events. Early detection and correction of anemia in patients with atrial fibrillation may have a positive impact on reducing these adverse events.

Intra-abdominal abscess in older patients: two atypical presentations to the Acute Medical Unit.

An abscess is a localised collection of necrotic tissue, white cells and bacteria, collectively forming pus. Intra-abdominal abscesses can occur viscerally (e.g. hepatic abscess), retroperitoneally (e.g. psoas abscess) or intraperitoneally (e.g. subphrenic abscess).(1, 2) Clinical presentation is variable and largely depends on the site of abscess. Fever and abdominal pain are the classic symptoms although in older people presentation can be non-specific. Prompt diagnosis and early intervention are vital for good outcomes.(3) We present two cases of older women whose presentation with atypical symptoms resulted in a delay in diagnosis.
