Glucocorticoids (GCs) may cause cognitive impairment through complex pathways involving specific receptors. In the human brain, hippocampal CA1 neurons exhibit the highest level of GCs receptors. Even the elderly expressed these receptors. The purpose of this brief review is to concentrate on the relationship between GCs and cognition in order to discuss the effects of the so-called steroid dementia in routine clinical practice.

Primary Sjögren’s syndrome (pSS) is a systemic autoimmune rheumatic disease where xerophthalmia, xerostomia and presence of anti-SSA and anti-SSB antibodies are typical features. Its prevalence is higher in over-65 aged population than in other age groups. In the elderly, pSS diagnosis comes up against a whole series of critical points that may favor its misdiagnosis. The aim of our article is to discuss the most relevant of them: the frequent occurrence of a seronegative subset, the presence of systemic features not related to sicca syndrome, the sicca syndrome as iatrogenic manifestation and the possibility of a biopsy false negative of labial salivary glands.

The aim of our study was to characterize the repolarization disorders propensity induced by drug-drug interaction. In this observational retrospective study, we report our experience on all elderly patients with ascertained diagnosis of coronavirus disease 2019 through nasopharyngeal swab with real time-polymerase chain reaction at our Pugliese-Ciaccio hospital in Catanzaro, who received hydroxychloroquine (HCQ), with or without azithromycin (AZY). 33 hospitalized patients were examined. We calculated QT value, cQT, QT dispersion, and cQT dispersion and examined possible progression on the basal electrocardiogram (T0) and after the insertion of the drug (T1). The QT value is increased by T0 vs T1 (370±40.74 vs 420±36.91 ms; P=0.000), as well as the cQT value (408±25.40 vs 451.54±58.81; P=0.003), the QT dispersion (QTd: 36.36±14.53 vs 50.90±13.12 ms; P=0.000); the dispersion of cQTc (cQTd 46.27±18.72 vs 63.18±21.93 ms; P=0.001). The ΔQT was 37.44±44.09 while the ΔcQT was 32.01±56.47). The main determinant of QTc prolongation is the number of drug at risk of prolongation of the QT that could influence the ventricular repolarization phase. The use of HCQ in combination with AZY, in patients suffering from severe acute respiratory syndrome-related coronavirus-2, can favor the onset of serious side effects, even potentially fatal. Finally, the measures of QTd and cQTd confirmed additional electrocardiographic parameters useful in identifying patients being treated with drugs at risk of potential adverse arrhythmic events following drug interaction.

Hydroxychloroquine is an antimalarial drug also known for its anti-inflammatory and antiviral effects, which have raised the interest of many researchers for its potential use in COVID-19 patients. It is known that this drug, being able to influence the cardiac repolarization phase with QTc interval prolongation, can be potentially harmful, chiefly in elderly subjects with frailty syndrome, several comorbidities and polypharmacotherapy. Therefore, although electrocardiogram monitoring of QTc prolongation is the focal point for reducing the arrhythmic risk of these patients, in order to identify the most exposed patients, the traditional Comprehensive Geriatric Assessment should be combined with a multiparametric risk score for QTc prolongation.

Purple urine bag syndrome (PUBS) is a rare condition that occurs predominantly in the elderly, immobilized and bearer of chronic bladder catheter. It is a phenomenon usually associated with urinary tract infection, particularly in the presence of high bacterial load. The presence of alkaline urine, constipation, high-protein diet and dehydration are predisposing factors. In most cases it is an asymptomatic condition. We described the case of an elderly patient admitted to the geriatric Department in which purple urine was found in the urine collection bag. The culture of urine showed the presence of infection with Klebsiella Pneumoniae. Targeted antibiotic treatment and proper hydration determined the resolution of the phenomenon and the resolution of the infection. Although it is an alarming phenomenon due to the particularity of the color of the urine, it is a treatable and solvable condition with an adequate specific antibiotic treatment. Prevention measures are equally effective and consist in eliminating the risk factors for this condition.

On 11 March 2020, the World Health Organization declared a pandemic state, in relation to the spread of the severe acute respiratory syndrome-coronavirus disease-2, responsible for the coronavirus disease-2019 (COVID-19). The pandemical blast of COVID-19 uncovered well known weakness of financial chain and put our economic organizations facing off dramatic consequences if new strategies will not be developed to adapt health-care on detailed sub-groups of patients. Frail individual aged >65 years affected by cardiovascular disease are an aged population that showed a particular attitude to contract infection and a higher mortality rate compared to general population. In this brief article, we will focus on the management of issues related to cardiovascular patients facing coronavirus infection, in particular in the most fragile groups of the population such as the elderly, increasingly numerous and affected by multimorbidity. Protecting aged populations will be a central question, probably primary in everyone's interest.

Glucocorticoids (GCs) are drugs commonly used for the treatment of a great number of acute or chronic pathological conditions. In a cross-sectional study we analyze a cohort of elderly patients treated for at least four weeks with a glucocorticoid (GC), exactly prednisone therapy, for a renal or rheumatological condition pointing out on functional, mental and clinical status. The main purpose was to assess change in cognitive performances. Corticosteroids administration also at low dosage in older subjects could enhance cognitive function. This observation should be proved in larger population and underlying mechanisms studied in deep.

The pandemic blast of COVID-19 uncovered well known weakness of financial chain and put our economic organizations facing off dramatic consequences if new strategies will not be developed to adapt health-care on detailed sub-groups of patients. The exponential number of older and frail subjects aged >65 years represents a challenge for public health. Patients affected by renal disease are an aged population that showed a particular attitude to contract infection and a higher mortality rate respect to general population. In this brief article, we would point out the focus on the management of issues related to renal patients facing off with coronavirus infection, in particular in a geriatric population particularly exposed to contagion like hemodialysis patients and precautions decided to slow the spread of contamination.

Fahr’s disease (FD), also known as familial idiopathic basal ganglia calcification, is a neurodegenerative disease affecting cerebral micro vessels, mainly in the basal ganglia. It mostly presents with movement disorders, dementia and behavioral abnormalities. It is considered hereditary with an autosomal dominant transmission. Fahr’s disease is often underestimated and under diagnosed. We reported the clinical differences found in two patients with Fahr’s Disease. In particular, we described a case of Fahr’s disease with behavioral alteration with extrapyramidal movement disorders, and a rare case of Fahr’s disease with cognitive and behavioral alterations in absence of extrapyramidal movement disorders.

Toxic epidermal necrolysis (TEN) or Lyell’s syndrome is a rare but serious potentially fatal autoimmune dermatologic disease. It is characterized by cutaneous damage due to apoptosis of the keratinocytes with consequent dermo-epidermal separation for a >30% extension of the body surface, associated with mucosal lesions. It is due to the activation of the immune system, often following the intake of potentially toxic drugs [antibiotics, antiepileptics, non-steroidal antinflammatory drugs (NSAIDs), allopurinol] or after infection with herpetic viruses or mycoplasma. We describe the case of an 82- year-old man starting therapy of Allopurinol for hyperuricemia. After four days the patient shows an extensive erythematous rash localized to the trunk and upper limbs. The following day the rash also involves the face, tending to the confluence and after another two days, the macules turn into de-epithelized areas because of dermo-epidermal separation and the lesions involve the oral and ocular mucosa, causing dysphagia and difficulty in speaking. He was treated with steroid and antihistamine therapy, suspending the previously undertaken therapy with antibiotic and Allopurinol.
