Growth of a progesterone receptor-positive meningioma in a female patient with congenital adrenal hyperplasia

Meningioma growth has been previously described in patients receiving oestrogen/progestogen therapy. We describe the clinical, radiological, biochemical and pathologic findings in a 45-year-old woman with congenital adrenal hyperplasia secondary to a defect in the 21-hydroxylase enzyme who had chronic poor adherence to glucocorticoid therapy with consequent virilisation. The patient presented with a frontal headache and marked right-sided proptosis. Laboratory findings demonstrated androgen excess with a testosterone of 18.1 nmol/L (0-1.5 nmol) and 17-Hydroxyprogesterone >180 nmol/L (<6.5 nmol/L). CT abdomen was performed as the patient complained of rapid-onset increasing abdominal girth and revealed bilateral large adrenal myelolipomata. MRI brain revealed a large meningioma involving the right sphenoid wing with anterior displacement of the right eye and associated bony destruction. Surgical debulking of the meningioma was performed and histology demonstrated a meningioma, which stained positive for the progesterone receptor. Growth of meningioma has been described in postmenopausal women receiving hormone replacement therapy, in women receiving contraceptive therapy and in transsexual patients undergoing therapy with high-dose oestrogen and progestogens. Progesterone receptor positivity has been described previously in meningiomas. 17-Hydroxyprogesterone is elevated in CAH and has affinity and biological activity at the progesterone receptor. Therefore, we hypothesise that patients who have long-standing increased adrenal androgen precursor concentrations may be at risk of meningioma growth.

LEARNING POINTS

Patients with long-standing CAH (particularly if not optimally controlled) may present with other complications, which may be related to long-standing elevated androgen or decreased glucocorticoid levels.Chronic poor control of CAH is associated with adrenal myelolipoma and adrenal rest tissue tumours.Meningiomas are sensitive to endocrine stimuli including progesterone, oestrogen and androgens as they express the relevant receptors.

Social relationships, loneliness, and mental health among older men and women in Ireland: A prospective community-based study

BACKGROUND

Data is lacking on the association of interpersonal stressors and social isolation with mental disorders and the mediating role of loneliness. Thus, we examined this association prospectively using community-based data.

METHODS

Data on 6105 adults aged ≥50 years from the Irish Longitudinal Study on Ageing (TILDA) was analyzed. Mental health outcomes were assessed 2 years after baseline. Depressive and anxiety symptoms were evaluated with validated scales. Multivariable linear regression and mediation analyses were conducted.

RESULTS

Higher levels of spousal support, less strain from spouse and better social network integration were protective against depressive symptoms in men. Social support from friends and children was protective against depressive symptoms in both genders. Higher levels of social strain from children were positively associated with depressive symptoms in women. Loneliness was a significant mediator in the majority of these associations.

CONCLUSION

Interventions aimed at increasing relationship quality and strengthening existing social network structures, with a specific focus on reducing feelings of loneliness, may be beneficial in the prevention of depressive symptoms among older adults.

Mild cognitive decline. A position statement of the Cognitive Decline Group of the European Innovation Partnership for Active and Healthy Ageing (EIPAHA)

INTRODUCTION

Mild cognitive impairment (MCI) is a term used to describe a level of decline in cognition which is seen as an intermediate stage between normal ageing and dementia, and which many consider to be a prodromal stage of neurodegeneration that may become dementia. That is, it is perceived as a high risk level of cognitive change. The increasing burden of dementia in our society, but also our increasing understanding of its risk factors and potential interventions, require diligent management of MCI in order to find strategies that produce effective prevention of dementia.

AIM

To update knowledge regarding mild cognitive impairment, and to bring together and appraise evidence about the main features of clinical interest: definitions, prevalence and stability, risk factors, screening, and management and intervention.

METHODS

Literature review and consensus of expert opinion.

RESULTS AND CONCLUSION

MCI describes a level of impairment in which deteriorating cognitive functions still allow for reasonable independent living, including some compensatory strategies. While there is evidence for some early risk factors, there is still a need to more precisely delineate and distinguish early manifestations of frank dementia from cognitive impairment that is less likely to progress to dementia, and furthermore to develop improved prospective evidence for positive response to intervention. An important limitation derives from the scarcity of studies that take MCI as an endpoint. Strategies for effective management suffer from the same limitation, since most studies have focused on dementia. Behavioural changes may represent the most cost-effective approach.

Prevalence of age-related macular degeneration in the Republic of Ireland

Background

Age-related macular degeneration (AMD) remains the most common cause of visual loss among subjects over 50 years of age in the developed world. The Irish Longitudinal study on Ageing (TILDA) is a population-based study of subjects aged 50 years or older, designed to investigate factors that influence ageing, and has enabled this investigation of the prevalence of AMD in the Republic of Ireland (ROI).

Methods

Data collected from a nationally representative sample of community-living older adults aged 50 years and over in ROI over the period November 2009 to July 2011. 5035 participants attended the TILDA health centre for assessment. Retinal photographs were obtained in 4859 of these participants. Retinal grading was performed in a masked fashion using a modified version of the International Classification and Grading System for AMD.

Results

Adjusting for lower response rates among older subjects, the estimated overall prevalence of any AMD was 7.2% (95% CI 6.5% to 7.9%) in the population aged 50 years or older. The estimated prevalence of early AMD was 6.6% (95% CI 5.9% to 7.3%), and the estimated prevalence of late AMD was 0.6% (95% CI 0.4% to 0.8%). Statistically significant associations with AMD included increasing age and family history of the condition.

Conclusions

This is the first study to provide prevalence estimates of AMD in ROI and will inform eye care professionals and policymakers involved in the delivery and planning of care for those afflicted with this condition.

Stressful life events and orthostatic blood pressure recovery in older adults

OBJECTIVE

The majority of the literature on stress and blood pressure (BP) concerns the increased risk of cardiovascular morbidity and mortality from high BP. Because the sympathetic nervous system is critical to the maintenance of orthostatic BP, it was hypothesized that older adults who have experienced more stressful life events (SLEs) would be more likely to show impaired recovery of BP in response to orthostatic stress.

METHOD

A total of 3,765 participants (Mage = 61.6 years, SD = 8.2; 54% female) from the first wave of The Irish Longitudinal Study on Ageing (TILDA) were included in the current analysis. Exposure to lifetime SLEs was ascertained by self-completion questionnaire, and beat-to-beat orthostatic BP measurement was carried out. Individuals who failed to recover at least 95% of their baseline BP by 60 s post stand were characterized as having impaired orthostatic BP recovery.

RESULTS

An independent, dose-response relationship between the number of SLEs reported and the odds of impaired systolic BP recovery was observed after adjustment for covariates (1 event: odds ratio [OR] = 1.19, 95% confidence interval [CI] [0.98, 1.45], p = .078; 2 events: OR = 1.33, 95% CI [1.03, 1.73], p = .031; 3 or more events: OR = 1.56, 95% CI [1.12, 1.73], p = .009). This relationship was not evident for diastolic BP recovery.

CONCLUSION

The reporting of a higher number of SLEs is associated with greater risk of impaired systolic BP recovery from orthostatic stress. Potential clinical implications include an increased risk of cerebral hypoperfusion, which predisposes older adults to falls, faints, and changes in cognitive status.

Sexual risk behavior, alcohol use, and social media use among secondary school students in informal settlements in Cape Town and Port Elizabeth, South Africa

South Africa's HIV prevalence among young people remains among the highest in the world. A cross-sectional study was carried out in 2012 to estimate prevalences of sexual risk behavior and hazardous alcohol use (HAU) (via the Alcohol Use Disorder Identification Test) as well as to investigate potential associations between these outcomes and social media use. In all, 4485 students (mean age 15.66 years, SD 1.39) at 46 secondary schools in informal settlements in Cape Town and Port Elizabeth completed mobile-phone-assisted, self-administered baseline questionnaires within a cluster-randomized trial. In all, 312 females (12.5 %) and 468 males (23.5 %) screened positive for HAU (AOR = 1.98, 95 % CI 1.69-2.34). 730 males (39.9 %) and 268 females (11.8 %) reported having had two or more partners in the last year (AOR = 3.46, 95 % CI 2.87-4.16). Among females, having a Facebook account was associated with reported multiple partnerships in the last year (AOR = 1.81, 95 % CI 1.19-2.74), age-disparate sex in the last year (AOR = 1.96, 95 % CI 1.16-3.32) and HAU (AOR = 1.97, 95 % CI 1.41-2.74). Using Mxit-a popular mobile instant messaging application-was associated with higher odds of reported multiple partnerships in the last year among both males (AOR = 1.70, 95 % CI 1.35-2.14) and females (AOR = 1.45, 95 % CI 1.07-1.96) and with HAU among both males (AOR = 1.47, 95 % CI 1.14-1.90) and females (AOR = 1.50, 95 % CI 1.18-1.90). Further longitudinal and qualitative research should explore in more depth the observed links between social media and risk behavior.

Cognitive function is preserved in older adults with a reported history of childhood sexual abuse

Childhood sexual abuse (CSA) is associated with mood and cognitive deficits in children and young adults. Evidence suggests that the effects of early-life adversity persist throughout adulthood; however, the impact of CSA on cognition in older adults is largely unknown. This study investigated cognitive function in older adults with a reported history of CSA. Data are from a population-based study (The Irish Longitudinal Study on Ageing) of 6,912 adults aged 50 years and older. Participants answered questions about CSA as part of a stressful life events questionnaire. Global cognition, executive function, memory (both objective and self-rated), attention, and processing speed were measured via a comprehensive battery of tests. Anxiety and depression, other childhood adversity, health behaviours, chronic disease, and medication use were also assessed. Of the total sample, 6.5% reported CSA. These individuals were more likely to have experienced other forms of childhood adversity and to exhibit poor mental health compared to those who reported no history of CSA. Multivariate regression analyses revealed, however, that CSA was associated with better global cognition, memory, executive function, and processing speed, despite poorer psychological health in this group. Future studies should aim to investigate possible reasons for this finding.

Low macular pigment optical density is associated with lower cognitive performance in a large, population-based sample of older adults

Macular pigment (MP) is comprised of the carotenoids lutein (L), zeaxanthin (Z), and meso-zeaxanthin (MZ), which selectively accumulate at the macula (central retina) of the eye and are neuroprotective. These carotenoids are also present in the brain, and evidence suggests a close correlation between retinal and brain concentrations. We investigated the relationship between MP and cognitive function in 4453 adults aged ≥ 50 years as part of The Irish Longitudinal Study on Aging. Macular pigment optical density (MPOD) was determined using customized heterochromatic flicker photometry-a quick and noninvasive way of measuring the concentration of the pigment. Lower MPOD was associated with poorer performance on the mini-mental state examination (p = 0.026) and on the Montreal cognitive assessment (p = 0.016). Individuals with lower MPOD also had poorer prospective memory (p = 0.011), took longer time to complete a trail-making task (p = 0.003), and had slower and more variable reaction times on a choice reaction time task (p = 0.000 and 0.001). These associations were only slightly attenuated following adjustment for physical and mental health. There was no significant association between MPOD and verbal fluency, word recall, visual reasoning, or picture memory. Overall, the findings support the theory that xanthophyll carotenoids impact on cognitive function, underscoring the need for exploration of novel, noninvasive biomarkers for cognitive vulnerability and preventive strategies.

Education is positively associated with macular pigment: the Irish Longitudinal Study on Ageing (TILDA)

PURPOSE

The three carotenoids lutein, zeaxanthin, and meso-zeaxanthin, are found at the macula and referred to as macular pigment (MP). This study was undertaken to investigate determinants of MP in a large randomly selected sample from the Republic of Ireland (as part of The Irish Longitudinal Study on Ageing [TILDA]).

METHODS

MP optical density (MPOD) was measured using customized heterochromatic flicker photometry in 4373 participants. Sociodemographic and self reported health data was obtained using computer assisted personal interview (CAPI).

RESULTS

Mean (SD) MPOD for the study group was 0.203 (0.156) with a range of 0 to 1.01. MPOD was higher for participants with secondary education (mean [SD] = 0.205 [0.148]) than for those with only primary education or no education (mean [SD] = 0.183 [0.113]; P < 0.001). MPOD was also higher for those with tertiary education (mean [SD] = 0.232 [0.231]) compared with primary/no education or secondary education (P < 0.001 for both comparisons).

CONCLUSIONS

We report that MP is lower amongst those participants of a population-representative study who did not have secondary or third level education when compared with participants who had such education. Given the emerging evidence that MP is important for visual performance and comfort, and given the putative protection that this pigment confers against AMD (especially important in the context of increased risk of AMD in this social group), public health measures aimed at improving diet for this at-risk population need to be considered.

Age and cortisol levels modulate judgment of positive and negative facial expressions

There is some evidence that older adults respond to emotional stimuli differently to young adults, and that they may exhibit better performance on measures of memory and attention when stimuli are positive rather than negative in valence. A relation between cortisol levels and attention/memory for emotional stimuli in young adults has also been reported. The relationship between cortisol levels and the judgment of facial expressions of emotion in aging, however, has yet to be explored. The aim of this study was to investigate performance on a simple emotional face judgment task in young (N=37) and middle-aged (N=37) adults in association with salivary cortisol levels. Middle-aged participants were slower in responding to stimuli than younger participants. Cortisol levels were found to be associated with shorter response latencies to categorise emotional but not neutral faces, and with a greater tendency to judge neutral faces as being emotional. An interaction between age and cortisol levels emerged in response to angry faces; such that higher cortisol levels predicted significantly shorter reaction times to angry faces in young adults, but not in middle-aged adults. Thus, cortisol may be differently related to the processing of emotional facial expressions, particularly of anger, in middle-aged and young individuals. The findings are discussed in relation to the hypothesised changes in emotion regulation with aging.

Evidence for a specific defect in hippocampal memory in overt and subclinical hypothyroidism

CONTEXT

Declarative memory largely depends upon normal functioning temporal lobes (hippocampal complex) and prefrontal cortex. Animal studies suggest abnormal hippocampal function in hypothyroidism.

OBJECTIVE

The aim of the study was to assess declarative memory in overt and subclinical (SCH) hypothyroid patients before and after l-T(4) (LT4) replacement and in matched normal subjects.

DESIGN AND SETTING

A prospective, open-labeled interventional study was conducted at a teaching hospital.

PARTICIPANTS AND INTERVENTION

Hypothyroid (n = 21) and SCH (n = 17) patients underwent neuropsychological tests at baseline and 3 and 6 months after LT4 replacement. Normal subjects were studied at the same time-points.

MAIN OUTCOME

Tests of spatial, verbal, associative, and working memory; attention; and response inhibition and the Hospital Anxiety and Depression Scale were administered.

RESULTS

Baseline deficits in spatial, associative, and verbal memory, which rely upon the integrity of the hippocampal and frontal areas, were identified in patients with overt hypothyroidism. Spatial and verbal memory were impaired in SCH patients (P < 0.05). TSH levels correlated negatively (P < 0.05) with these deficits. After LT4 replacement, verbal memory normalized. Spatial memory normalized in the SCH group but remained impaired in the hypothyroid group. Associative memory deficits persisted in the overt hypothyroid group. Hospital Anxiety and Depression Scale scores did not correlate with cognitive function. Measures of attention and response inhibition did not differ from control subjects.

CONCLUSION

Cognitive impairment occurs in SCH and more markedly in overt hypothyroidism. These impairments appear predominantly mnemonic in nature, suggesting that the etiology is not indicative of general cognitive slowing. We propose that these deficits may reflect an underlying disruption of normal hippocampal function and/or connectivity.

An exploratory study of linguistic-colour associations across languages in multilingual synaesthetes

In one of the most common forms of synaesthesia, linguistic-colour synaesthesia, colour is induced by stimuli such as numbers, letters, days of the week, and months of the year. It is not clear, however, whether linguistic-colour synaesthesia is determined more by higher level semantic information--that is, word meaning--or by lower level grapheme or phoneme structure. To explore this issue, we tested whether colour is consistently induced by grapheme or phoneme form or word meaning in bilingual and trilingual linguistic-colour synaesthetes. We reasoned that if the induced colour was related to word meaning, rather than to the acoustic or visual properties of the words, then the induced colours would remain consistent across languages. We found that colours were not consistently related to word meaning across languages. Instead, induced colours were more related to form properties of the word across languages, particularly visual structure. However, the type of inducing stimulus influenced specific colour associations. For example, colours to months of the year were more consistent across languages than were colours to numbers or days of the week. Furthermore, the effect of inducing stimuli was also associated with the age of acquisition of additional languages. Our findings are discussed with reference to a critical period in language acquisition on synaesthesia.

Imaging of acute pyelonephritis in the adult

The diagnosis of acute pyelonephritis in adults is predominantly made by a combination of typical clinical features of flank pain, high temperature and dysuria combined with urinalysis findings of bacteruria and pyuria. Imaging is generally reserved for patients who have atypical presenting features or in those who fail to respond to conventional therapy. In addition, early imaging may be useful in diabetics or immunocompromised patients. In such patients, imaging may not only aid in making the diagnosis of acute pyelonephritis, but more importantly, it may help identify complications such as abscess formation. In this pictorial review, we discuss the role of modern imaging in acute pyelonephritis and its complications. We discuss the growing role of cross-sectional imaging with computed tomography (CT) and novel magnetic resonance imaging (MRI) techniques that may be used to demonstrate both typical as well as unusual manifestations of acute pyelonephritis and its complications. In addition, conditions such as emphysematous and fungal pyelonephritis are discussed.
