Update on Atopic Dermatitis: Diagnosis, Severity Assessment, and Treatment Selection

Atopic dermatitis (AD) is one of the most common inflammatory skin diseases affecting children and adults. The intense pruritus and rash can be debilitating, significantly impairing quality of life. Until recently, treatment was largely nonspecific and, in severe disease, sometimes ineffective and/or fraught with many side effects. Now, multiple agents targeting specific disease pathways are available or in development. Two new therapies, crisaborole and dupilumab, have become available since 2016, and dupilumab has dramatically improved outcomes for adults with severe AD. This article provides an overview of AD, including strategies for differential diagnosis and assessment of disease severity to guide treatment selection. Key clinical trials for crisaborole and dupilumab are reviewed, and other targeted treatments now in development are summarized. Two cases, representing childhood-onset and adult-onset AD, are discussed to provide clinical context for diagnosis, severity assessment, and treatment selection and outcomes.

Phenotypical Differences of Childhood- and Adult-Onset Atopic Dermatitis

BACKGROUND

Little is known about adult-onset atopic dermatitis (AD).

OBJECTIVE

To determine the associations and clinical characteristics of adult-onset AD.

METHODS

A prospective study of 356 adults with AD (age ≥18 years) was performed using standardized questionnaires and examination. AD severity was assessed using the Patient-Oriented Eczema Measure, Eczema Area and Severity Index, Scoring Atopic Dermatitis, body surface area, and numeric rating scale for itch and sleeplessness. Latent class analysis was used to determine dominant clinical phenotypes. Multivariate logistic regression was used to determine the relationship between adult-onset AD and distinct phenotypes.

RESULTS

One hundred forty-nine adults (41.9%) reported onset of AD during adulthood, with 87 (24.4%) after the age of 50 years. Adult- versus childhood-onset AD was associated with birthplace outside the United States (χ2, P = .0008), but not sex, race/ethnicity, current smoking status, or alcohol consumption (P ≥ .11); and decreased personal history of asthma, hay fever, and food allergy and family history of asthma and food allergy (P ≤ .0001 for all). There was no significant difference in the Eczema Area and Severity Index, Scoring Atopic Dermatitis, body surface area, numeric rating scale for itch and sleeplessness, or Patient-Oriented Eczema Measure between adult- and childhood-onset AD (Mann-Whitney U test, P ≥ .10). Latent class analysis identified 3 classes: (1) high probability of flexural dermatitis and xerosis with intermediate to high probabilities of head, neck, and hand dermatitis; (2) high probability of flexural dermatitis and xerosis, but low probabilities of head, neck, and hand dermatitis; and (3) lower probability of flexural dermatitis, but the highest probabilities of virtually all other signs and symptoms. Adult-onset AD was significantly associated with class 1 (multivariate logistic regression; adjusted odds ratio, 5.54; 95% CI, 1.59-19.28) and class 3 (adjusted odds ratio, 14.03; 95% CI, 2.33-85.50).

CONCLUSIONS

Self-reported adult-onset AD is common and has distinct phenotypes with lesional predilection for the hands and/or head/neck.

Lung function impairment increases with age of diagnosis in adult onset asthma

BACKGROUND

Asthma-onset in older individuals has been associated with an accelerated decline in lung function, but direct comparisons with younger adults have not been reported.

METHODS

In a random population sample comprising 4983 individuals from the Copenhagen City Heart Study without asthma at baseline, we compared young (<35 years), middle-aged (35-64 years) and older (>64 years) adults with newly diagnosed asthma during a 10-year follow-up.

RESULTS

The proportion of cases with newly diagnosed asthma during follow-up was similar across age groups (Older adults: 7% (84/1168), middle-aged adults: 7% (223/3147), and young adults: 6% (42/668) (p = ns)). In all three age groups, lung function was reduced at baseline in subjects who were subsequently diagnosed with asthma, but most pronounced in those >35 years. (Mean FEV1%: Young 90.2% (±13.9), middle-aged 80.8% (±20.8), and older adults 80.8% (±24.2), p < 0.001). Furthermore, incident asthma was associated with an accelerated decline in lung function in older adults (young adults 11.0 mL/year, middle-aged adults 18.2 mL/year, and older adults 30.8 mL/year). These differences were independent of FEV1 at baseline and smoking status, and were not explained by undiagnosed asthma in older adults, as the frequency of respiratory symptoms, including wheeze, was similar in all three age groups at baseline.

CONCLUSIONS

Asthma was diagnosed as frequently in older as in younger adults. Preexisting symptoms were equally common, but lung function was more reduced pre-diagnosis, and declined more rapidly in older adults. This emphasizes the need for a high level of therapeutic attention in patients with asthma diagnosed late in life.

Clinical, biochemical and molecular investigation of adult-onset glutaric acidemia type II: Characteristics in comparison with pediatric cases

INTRODUCTION

An increasing number of adult patients have been diagnosed with fatty acid β-oxidation disorders with the rising use of diagnostic technologies. In this study, clinical, biochemical, and molecular characteristics of 2 Japanese patients with adult-onset glutaric acidemia type II (GA2) were investigated and compared with those of pediatric cases.

METHODS

The patients were a 58-year-old male and a 31-year-old male. In both cases, episodes of myopathic symptoms, including myalgia, muscle weakness, and liver dysfunction of unknown cause, had been noted for the past several years. Muscle biopsy, urinary organic acid analysis (OA), acylcarnitine (AC) analysis in dried blood spots (DBS) and serum, immunoblotting, genetic analysis, and an in vitro probe acylcarnitine (IVP) assay were used for diagnosis and investigation.

RESULTS

In both cases, there was no obvious abnormality of AC in DBS or urinary OA, although there was a increase in medium- and long-chain ACs in serum; also, fat deposits were observed in the muscle biopsy. Immunoblotting and gene analysis revealed that both patients had GA2 due to a defect in electron transfer flavoprotein dehydrogenase (ETFDH). The IVP assay indicated no special abnormalities in either case.

CONCLUSION

Late-onset GA2 is separated into the intermediate and myopathic forms. In the myopathic form, episodic muscular symptoms or liver dysfunction are primarily exhibited after later childhood. Muscle biopsy and serum (or plasma) AC analysis allow accurate diagnosis in contrast with other biochemical tests, such as analysis of AC in DBS, urinary OA, or the IVP assay, which show fewer abnormalities in the myopathic form compared to intermediate form.

Adult-Onset Atopic Dermatitis

One in 4 adults with atopic dermatitis (AD) report adult-onset disease. Adult-onset AD appears to be associated with a different disease phenotype compared with childhood-onset AD. A broad differential diagnosis must be considered in a patient presenting with an adult-onset eczematous eruption, including allergic contact dermatitis, mycosis fungoides/cutaneous T-cell lymphoma, psoriasis, scabies, and so forth. This review will specifically address the diagnosis, workup, and management of adult-onset AD. In adults presenting a new-onset chronic eczematous eruption, consideration should be given to a diagnosis of adult-onset AD. Patch testing should be performed to rule out allergic contact dermatitis. A biopsy may be obtained to exclude alternative diagnoses, including cutaneous T-cell lymphoma and psoriasis.

Comparing illness presentation, treatment and functioning between patients with adolescent- and adult-onset psychosis

Studies have shown that early- and adult-onset schizophrenia patients differ in pre-morbid traits, illness presentation, psychopathology, and prognosis. We aimed to compare adult-onset patients (age range 26-55 years) with an adolescent-onset cohort (15-25 years) in demographics, illness presentation and functioning at baseline. Participants were from two territory-wide early intervention services for adolescent-onset (n=671) and adult-onset psychosis patients (n=360) in Hong Kong. The adolescent-onset cohort had their initial psychotic episode from 2001-2003; retrospective data collection was done through systematic case note review. The adult-onset cohort was recruited for a larger interventional study from 2009-2011; information was collected via face-to-face interviews. Adult-onset psychosis was significantly associated with more females, more smokers, more non-local birth, more full-time employment, better functioning, poorer medication adherence, more psychiatric hospitalization and fewer with schizophrenia than adolescent-onset psychosis (mean age: 20.4). The effect sizes were small, except for medication adherence where a robust effect was found. No group difference in DUP was found. The finding that adult-onset patients had better functioning challenges the view that adolescent- and adult-onset psychoses share a similar prognostic trajectory. Implications for adapting intervention processes for adolescent- and adult-onset psychosis are discussed.

Copy Number Variations in Adult-onset Neuropsychiatric Diseases

Adult-onset neuropsychiatric diseases are one of the most challenging areas of medicine. While symptomatic treatments are available, for most of these diseases the exact pathomechanism is not known, thus, disease-modifying therapies are difficult to conceptualize and find. The two most common and best studied neuropsychiatric diseases affecting higher cortical functions in humans are schizophrenia and Alzheimer's disease; both diseases have high heritability, however, the genetic architecture is not fully elucidated. Robust Single Nucleotide Variant (SNV) studies have identified several loci with modest effect sizes. While Copy Number Variants (CNV) make an important contribution to genetic variation, CNV GWAS suffer from dependence on mainly SNP arrays with underperforming genotyping accuracy. We evaluated dynamic range of the assays for three types of CNV loci, including biallelic deletion, high copy gain, and fusion gene, to assess the depth of exploration of the contribution of CNVs to disease susceptibility. Despite the suboptimal genotyping, novel mechanisms are emerging and further large-scale studies with genotyping assays optimized for CNV detection are needed. Furthermore, the CHRFAM7A human-specific fusion gene association warrants large scale locus specific association studies in AD, schizophrenia, bipolar disorder and ADHD.

Adult onset of ganglioneuroblastoma of the adrenal gland: case report and review of the literature

Ganglioneuroblastoma (GBN) is a malignant neoplasm of the autonomic nervous system. Adult onset of ganglioneuroblastoma is extremely rare. Only 16 cases have been reported in English literature, to date. Surgery represents the first-line therapy for the treatment of ganglioneuroblastoma. Radiation therapy is indicated in patients with localized unresectable disease. Chemotherapy is reserved for metastatic disease.

We present the case of a 63-year-old man affected by ganglioneuroblastoma of the adrenal gland. The diagnosis was made incidentally. The tumor, measuring 5 × 3 cm, was successfully surgically removed.

Adult-onset Atopic Dermatitis

Adult-onset atopic dermatitis is still an under recognized condition as there are only few studies regarding this entity. As compared to childhood onset atopic dermatitis, clinical features of adult onset atopic dermatitis are still not categorized. Adult atopic dermatitis can present for the first time in adult age with atypical morphology or may progress from childhood onset. This article reviews the characteristic clinical features of adult atopic dermatitis, associated risk factors and management.

Adult onset seizures: Clinical, etiological, and radiological profile

Introduction:

Adult onset seizure disorder is a major public health concern in terms of burden of disease, nature of illness, and its impact on individual, family, and community. This study was done to assess the clinical profile and etiology of adult onset seizures and correlates of clinical and radiological pattern.

Materials and Methods:

This was a prospective cross-sectional hospital-based study conducted on 100 cases presenting with adult onset seizures.

Results:

Adult onset seizures were most prevalent in the young and middle-aged adults than elderly; generalized seizures were more common than focal seizures. However, the incidence of generalized seizures showed a falling trend as the age advanced whereas focal seizures increased in incidence with advancing age. Overall, the most common etiology of seizures was stroke, followed by idiopathic and central nervous system infections; yet, most common etiology of adult onset generalized and focal seizures was idiopathic and stroke, respectively. Regarding etiology, among younger adults, idiopathic seizures were predominant, whereas among middle aged and elderly, stroke was the most common etiology.

Conclusions:

It is mandatory to deal carefully with each case of adult onset seizure with a tailor-made approach. Identification and awareness about the etiological factors and seizure type help in better management of these patients. Primary care physicians play a pivotal role in identifying patients with adult onset seizures and should encourage these patients to undergo neuroimaging so as to arrive at an appropriate etiological diagnosis. In the face of recent advances in neuroimaging techniques, the future prospective management of adult onset seizures appears bright and convincing.

A longitudinal study of a family with adult-onset autosomal dominant leukodystrophy: Clinical, autonomic and neuropsychological findings

BACKGROUND AND PURPOSE

Adult-onset autosomal dominant leukodystrophy (ADLD) is a rare progressive neurological disorder caused by Lamin B1 duplication (LMNB1). Our aim was to investigate longitudinally the pattern of the autonomic dysfunction and the degree of neuropsychological involvement.

METHODS

Three related ADLD patients and one asymptomatic carrier of LMNB1 duplication underwent a standardized evaluation of autonomic nervous system, including cardiovascular reflexes, pharmacological testing, microneurography, skin biopsy, Metaiodobenzylguanidine scintigraphy and a complete neuropsychological battery.

RESULTS

An early neurogenic orthostatic hypotension was detected in all patients and confirmed by a low rise in noradrenaline levels on Tilt Test. However infusion of noradrenaline resulted in normal blood pressure rise as well as the infusion of clonidine. At the insulin tolerance test the increase in adrenaline resulted pathological in two out three patients. Microneurography failed to detect muscle sympathetic nerve activity bursts. Skin biopsy revealed a poor adrenergic innervation, while cardiac sympathetic nerves were normal. None of ADLD patients showed a global cognitive deficit but a selective impairment in the executive functions.

CONCLUSION

Autonomic disorder in ADLD involves selectively the postganglionic sympathetic system including the sympatho-adrenal response. Cognitive involvement consisting in an early impairment of executive tasks that might precede brain MR abnormalities.

The relationship between islet autoantibody status and the genetic risk of type 1 diabetes in adult-onset type 1 diabetes

AIMS/HYPOTHESIS

The reason for the observed lower rate of islet autoantibody positivity in clinician-diagnosed adult-onset vs childhood-onset type 1 diabetes is not known. We aimed to explore this by assessing the genetic risk of type 1 diabetes in autoantibody-negative and -positive children and adults.

METHODS

We analysed GAD autoantibodies, insulinoma-2 antigen autoantibodies and zinc transporter-8 autoantibodies (ZnT8A) and measured type 1 diabetes genetic risk by genotyping 30 type 1 diabetes-associated variants at diagnosis in 1814 individuals with clinician-diagnosed type 1 diabetes (1112 adult-onset, 702 childhood-onset). We compared the overall type 1 diabetes genetic risk score (T1DGRS) and non-HLA and HLA (DR3-DQ2, DR4-DQ8 and DR15-DQ6) components with autoantibody status in those with adult-onset and childhood-onset diabetes. We also measured the T1DGRS in 1924 individuals with type 2 diabetes from the Wellcome Trust Case Control Consortium to represent non-autoimmune diabetes control participants.

RESULTS

The T1DGRS was similar in autoantibody-negative and autoantibody-positive clinician-diagnosed childhood-onset type 1 diabetes (mean [SD] 0.274 [0.034] vs 0.277 [0.026], p=0.4). In contrast, the T1DGRS in autoantibody-negative adult-onset type 1 diabetes was lower than that in autoantibody-positive adult-onset type 1 diabetes (mean [SD] 0.243 [0.036] vs 0.271 [0.026], p<0.0001) but higher than that in type 2 diabetes (mean [SD] 0.229 [0.034], p<0.0001). Autoantibody-negative adults were more likely to have the more protective HLA DR15-DQ6 genotype (15% vs 3%, p<0.0001), were less likely to have the high-risk HLA DR3-DQ2/DR4-DQ8 genotype (6% vs 19%, p<0.0001) and had a lower non-HLA T1DGRS (p<0.0001) than autoantibody-positive adults. In contrast to children, autoantibody-negative adults were more likely to be male (75% vs 59%), had a higher BMI (27 vs 24 kg/m²) and were less likely to have other autoimmune conditions (2% vs 10%) than autoantibody-positive adults (all p<0.0001). In both adults and children, type 1 diabetes genetic risk was unaffected by the number of autoantibodies (p>0.3). These findings, along with the identification of seven misclassified adults with monogenic diabetes among autoantibody-negative adults and the results of a sensitivity analysis with and without measurement of ZnT8A, suggest that the intermediate type 1 diabetes genetic risk in autoantibody-negative adults is more likely to be explained by the inclusion of misclassified non-autoimmune diabetes (estimated to represent 67% of all antibody-negative adults, 95% CI 61%, 73%) than by the presence of unmeasured autoantibodies or by a discrete form of diabetes. When these estimated individuals with non-autoimmune diabetes were adjusted for, the prevalence of autoantibody positivity in adult-onset type 1 diabetes was similar to that in children (93% vs 91%, p=0.4).

CONCLUSIONS/INTERPRETATION

The inclusion of non-autoimmune diabetes is the most likely explanation for the observed lower rate of autoantibody positivity in clinician-diagnosed adult-onset type 1 diabetes. Our data support the utility of islet autoantibody measurement in clinician-suspected adult-onset type 1 diabetes in routine clinical practice.

Refractory coats' disease of adult onset

Purpose

We present the case of an 18-year-old Caucasian male with a unilateral macular star and retinal vascular anomalies compatible with adult onset Coats’ disease.

Methods

Diagnosis was based on fundoscopic, fluorescein angiography and optical coherence tomography findings.

Results

The patient presented to our emergency department with complaints of low vision in his left eye (LE) detected 10 days before. The best-corrected visual acuity in the LE was 20/50. Fundoscopy of the LE evidenced a complete macular star. Optical coherence tomography showed increased retinal thickness, infiltration of the retinal wall, and detachment of the neuroepithelium. Angiography revealed no appreciable diffusion in the macula. Above the superior temporal (ST) arcade, anomalies in the retinal vasculature were found, with interruption of the peripheral vessels and vessels which were ‘sausage’-like. After 1 month, the LE vision evolved to hand movements. Laser photocoagulation was performed in the ST quadrant. Intravitreal injection of bevacizumab 1.25 mg/0.05 ml and photodynamic therapy were performed without any significant changes, progression of ST serous detachment of the neuroepithelium, and finally progression to macular fibrosis.

Discussion

Coats’ disease is usually diagnosed in childhood, but rare cases may occur in adults. Those cases usually have a more indolent course which was not observed in our patient. When there is macular involvement, prognosis is more guarded, despite treatment.

The Clinicopathological Characteristics of Henoch-Schönlein Purpura Nephritis with Presentation of Nephrotic Syndrome

BACKGROUND

Henoch-Schönlein purpura nephritis (HSPN) is a common vasculitis involving the kidneys, with a lower incidence in adults. Meanwhile, nephrotic syndrome (NS) can appear in HSPN. However, the clinicopathological features and renal outcome of adult-onset HSPN presenting with NS (NS-HSPN) have not been well clarified.

METHODS

A total of 191 HSPN patients were prospectively analyzed and comparisons were made between NS-HSPN and non-NS-HSPN. Multivariate Cox regression analysis was carried out to find the unfavorable factors of renal outcome of NS-HSPN.

RESULTS

Among the 191 patients, 44 (23.0%) had NS-HSPN. Apart from edema and abdominal pain, patients with NS-HSPN tended to have lower levels of erythrocytes and hemoglobulin in blood as well as a greater number of erythrocytes in urine (p < 0.05). Mesangial proliferation was the most common pathological lesion in HSPN and the rates of crescent formation were significantly different, with 54.5% in NS-HSPN and 33.3% in non-NS-HSPN (p < 0.05). Notably, 18.2 and 4.8% of patients reached the composite endpoints in the NS-HSPN and non-NS-HSPN groups, respectively (p < 0.05), demonstrating that NS-HSPN patients were more likely to progress to end-stage renal disease and had a worse outcome. We also found that hypertension, estimated glomerular filtration rate (eGFR), cystatin, and tubular atrophy/interstitial fibrosis (HR > 1, p < 0.05) at onset were correlated with adverse outcome in NS-HSPN.

CONCLUSION

NS-HSPN had more severe clinicopathological manifestations and poorer prognosis. The adverse predictors of NS-HSPN principally depend on clinicopathological presentation rather than on different therapies, and hypertension, eGFR, cystatin, and tubular atrophy/interstitial fibrosis can serve as independent risk factors in NS-HSPN.

Parents' decision-making regarding whether to receive adult-onset only genetic findings for their children: Findings from the BabySeq Project

PURPOSE

Most professional guidelines recommend against genetic screening for adult-onset only (AO) conditions until adulthood, yet others argue that there may be benefit to disclosing such results. We explored parents' decision-making on this issue in the BabySeq Project, a clinical trial of newborn genomic sequencing.

METHODS

We conducted interviews with parents (N = 24) who were given the option to receive actionable AO results for their children. Interviews explored parents' motivations to receive and reasons to decline AO genetic disease risk information, their decision-making process, and their suggestions for supporting parents in making this decision.

RESULTS

Parents noted several motivations to receive and reasons to decline AO results. Most commonly, parents cited early intervention/surveillance (n = 11), implications for family health (n = 7), and the ability to prepare (n = 6) as motivations to receive these results. The most common reasons to decline were protection of the child's future autonomy (n = 4), negative effect on parenting (n = 3), and anxiety about future disease (n = 3). Parents identified a number of ways to support parents in making this decision.

CONCLUSION

Results show considerations to better support parental decision-making that aligns with their values when offering AO genetic information because it is more commonly integrated into pediatric clinical care.

Prodromal symptoms and the duration of untreated psychosis in first episode of psychosis patients: what differences are there between early vs. adult onset and between schizophrenia vs. bipolar disorder?

To assess the role of age (early onset psychosis-EOP < 18 years vs. adult onset psychosis-AOP) and diagnosis (schizophrenia spectrum disorders-SSD vs. bipolar disorders-BD) on the duration of untreated psychosis (DUP) and prodromal symptoms in a sample of patients with a first episode of psychosis. 331 patients with a first episode of psychosis (7-35 years old) were recruited and 174 (52.6%) diagnosed with SSD or BD at one-year follow-up through a multicenter longitudinal study. The Symptom Onset in Schizophrenia (SOS) inventory, the Positive and Negative Syndrome Scale and the structured clinical interviews for DSM-IV diagnoses were administered. Generalized linear models compared the main effects and group interaction. 273 AOP (25.2 ± 5.1 years; 66.5% male) and 58 EOP patients (15.5 ± 1.8 years; 70.7% male) were included. EOP patients had significantly more prodromal symptoms with a higher frequency of trouble with thinking, avolition and hallucinations than AOP patients, and significantly different median DUP (91 [33-177] vs. 58 [21-140] days; Z = - 2.006, p = 0.045). This was also significantly longer in SSD vs. BD patients (90 [31-155] vs. 30 [7-66] days; Z = - 2.916, p = 0.004) who, moreover had different profiles of prodromal symptoms. When assessing the interaction between age at onset (EOP/AOP) and type of diagnosis (SSD/BD), avolition was significantly higher (Wald statistic = 3.945; p = 0.047), in AOP patients with SSD compared to AOP BD patients (p = 0.004). Awareness of differences in length of DUP and prodromal symptoms in EOP vs. AOP and SSD vs. BD patients could help improve the early detection of psychosis among minors.

Adult-onset Leigh's disease: A rare entity

Leigh syndrome (LS) is a heterogeneous familial or sporadic neurodegenerative disorder. It is typically seen in infancy or childhood, although rare cases of adult onset have been described. The authors describe a 37-year-old woman who presented with protracted gastrointestinal symptoms followed by acute brain stem syndrome with severe metabolic acidosis and who subsequently showed dramatic clinical and neuroradiological improvement.

Social network drinking and family history contribute equally to first-onset alcohol dependence in high risk adults

BACKGROUND

Adult alcohol consumption is influenced by peer consumption, but whether peer drinking is associated with first-onset alcohol dependence (AD) in adults after age 30 is unknown.

METHODS

703 adult participants in the St. Louis Epidemiologic Catchment Area Survey (ECA) with no prior history of AD, but with high risk based on previously reported drinking or family history, were re-interviewed 11 years after the last ECA assessment to detect new cases of AD (age at follow-up: M(S.D.)=42.9 (8.2)). Incident AD during the assessment interval was examined in relation to drinking patterns in the social network and history of alcohol problems in parents.

RESULTS

Fifteen percent of the sample had a first-onset of AD; another 19.5% never developed AD but were high-risk drinkers at follow-up. Of those who developed AD, 32.1% were remitted and 67.9% were unremitted (current AD) or unstably remitted (asymptomatic high-risk drinkers). Compared to abstinent or low-risk drinkers who did not develop AD, high-risk drinkers with no AD and unremitted/unstably remitted individuals were 4 times as likely to report moderate drinkers in their networks and remitted individuals were nearly 3 times as likely to report network members in recovery from alcohol problems. Associations of social network drinking with remitted and current AD were similar in strength to those of parental alcohol problems.

CONCLUSIONS

Social network drinking patterns are associated with high-risk drinking and with the development of incident AD in adults, with effects equal to that of alcohol problems in both parents.

Adult onset retinoblastoma: A diagnostic dilemma

Retinoblastoma is the most common intraocular tumor of childhood. About 95% of retinoblastoma cases are diagnosed before the age of 5 years. Not more than 30 cases of Adult-onset retinoblastoma have been reported in literature. A 32 year old male presented with a painful blind eye. There was sudden loss of vision accompanied by severe pain and redness in right eye about 1 year ago, for which some surgery was done with neither a gain in vision nor any relief from pain. Then he was put on maximum tolerable medical therapy, later cyclocryotherapy was done. Now he presented to us with complains of extreme pain and bleeding from right eye since 2 days. There is no history of any ocular trauma. Right eye had no perception of light & showed anterior staphyloma with perforation. Right eye evisceration was done & material sent for histopathological examination, which revealed an adult-onset retinoblastoma. CECT scan revealed thickening of optic nerve throughout its entire length with contrast enhancement. He was further taken up for enucleation of residual sclera with maximum optic nerve stump removal to reconfirm the diagnosis. Histopathological examination revealed tumor deposits present in orbital soft tissue, resection margins and optic nerve cut end.Retinoblastoma presenting in adult age creates a diagnostic dilemma because of its low frequency and atypical features. We want to highlight the importance of high clinical suspicion and imaging modalities before taking any patient for evisceration with unexplained vision loss. One should send the eviscerated material for histopathological examination.

Atypical MRI features in familial adult onset Alexander disease: case report

Background

Alexander disease (AxD) is a rare neurological disease, especially in adults. It shows variable clinical and radiological features.

Case presentation

We diagnosed a female with AxD presenting with paroxysmal numbness of the limbs at the onset age of 28-year-old, progressing gradually to spastic paraparesis at age 30. One year later, she had ataxia, bulbar paralysis, bowel and bladder urgency. Her mother had a similar neurological symptoms and died within 2 years after onset (at the age of 47), and her maternal aunt also had similar but mild symptoms at the onset age of 54-year-old. Her brain magnetic resonance imaging (MRI) showed abnormal signals in periventricular white matter with severe atrophy in the medulla oblongata and thoracic spinal cord, and mild atrophy in cervical spinal cord, which is unusual in the adult form of AxD. She and her daughter’s glial fibrillary acidic protein (GFAP) gene analysis revealed the same heterozygous missense mutation, c.1246C > T, p.R416W, despite of no neurological symptoms in her daughter.

Conclusions

Our case report enriches the understanding of the familial adult AxD. Genetic analysis is necessary when patients have the above mentioned symptoms and signs, MRI findings, especially with family history.

A pathologically proven case of adult-onset HIV-related lymphocytic interstitial pneumonia with acute exacerbation treated with steroid and antiretroviral therapy

Lymphocytic interstitial pneumonia (LIP) is a rare opportunistic illness in human immunodeficiency virus (HIV)-infected adults, although it is relatively common among HIV-infected children. Most adult cases have been reported in African and Afro-Caribbean patients and few cases have been reported from Asia. Acute exacerbation of HIV-related LIP has not been well described. Here we report a pathologically proven case of acute exacerbation of adult-onset HIV-related LIP. The patient was an African immigrant living in Japan who presented with chronic dyspnea and diffuse bilateral pulmonary infiltrates. His clinical, radiological, and pathological findings were consistent with those of LIP. After a diagnostic surgical lung biopsy, his hypoxemia and pulmonary infiltrates exacerbated rapidly over a few days, although his condition had not progressed during the previous year. LIP may be an important differential diagnosis among adult patients in Asian countries, especially patients of non-Asian ethnicity.

Comparison of disability and quality of life between patients with pediatric and adult onset paraplegia

OBJECTIVE

To investigate the factors that affect disability and quality of life in patients with spinal cord injuries (SCIs) and to compare the degree of disability and quality of life in patients with SCI according to over and under 18 years of age when their injury occurred.

DESIGN

Cohort study.

SETTING

Two academic hospitals in Istanbul, Turkey.

PARTICIPANTS

Forty patients with SCI were included in this study. Group 1 included 20 patients with SCI who were younger than 18 years of age when their injury occurred, Group 2 included 20 patients who were older than 18 years of age when their injury occurred.

OUTCOME MEASURES

Patients' demographics, duration of SCI and degree of disability were assessed using the Craig Handicap Assessment and Reporting Technique (CHART). Quality of life was assessed using the World Health Organization Quality of Life Scale Short Form (WHOQOL-Bref). Depression was assessed using the Beck Depression Inventory (BDI).

RESULTS

Although there was no significant difference between the BDI scores and CHART scores of the two groups, environment domain scores in the WHOQOL-Bref were significantly higher in Group 2 than in Group 1 (P<0.05). No significant correlation was found between age of SCI onset, disease duration, ASIA scores, depression scores, total CHART scores for all patients.

CONCLUSION

Adaptation to environment was significantly better in those who suffered SCI during adulthood than in pediatric patients with SCI. Disability level was not associated with age of disease onset, disease duration, neurological status, depression level.

Autosomal recessive adult onset ataxia

Autosomal recessive ataxias (ARCA) represent a complex group of diseases ranging from primary ataxias to rare and complex metabolic disorders in which ataxia is a part of the clinical picture. Small number of ARCA manifest exclusively in adulthood, while majority of typical childhood onset ARCA may also start later with atypical clinical presentation. We have systematically searched the literature for ARCA with adult onset, both in the group of primary ataxias including those that are less frequently described in isolated or in a small number of families, and also in the group of complex and metabolic diseases in which ataxia is only part of the clinical picture. We propose an algorithm that could be used when encountering a patient with adult onset sporadic or recessive ataxia in whom the acquired causes are excluded. ARCA are frequently neglected in the differential diagnosis of adult-onset ataxias. Rising awareness of their clinical significance is important, not only because some of these disorders may be potentially treatable, but also for prognostic implications and inclusion of patients to future clinical trials with disease modifying agents.
