Comparative Study of Quality of Life and Obsessive-Compulsive Tendencies in Patients With Chronic Hand Eczema and Lichen Simplex Chronicus

'Eczematous' dermatitis of the nipple: clinical and histopathological differential diagnosis of Paget disease

The nipple can be affected by many malignant and benign entities. A wide variety of diseases including Paget disease, atopic dermatitis and nipple candidiasis can cause eczema-like changes in the nipple. In cases of diagnostic uncertainty, tissue sampling may be indicated. A true eczematous lesion, such as atopic dermatitis, typically shows a spongiotic dermatitis pattern. Paget disease, on the other hand, presents with infiltration of the nipple epidermis by neoplastic cells. The presence of atypical cells scattered in the epidermis in a pagetoid pattern opens up a histopathological differential diagnosis encompassing squamous cell carcinoma in situ and malignant melanoma, among others. Immunohistochemistry is commonly used to render a diagnosis. The objective of this article is to discuss Paget disease and highlight relevant clinical and histopathological differential diagnoses.

More than a skin disease: stress, depression, anxiety levels, and serum neurotrophins in lichen simplex chronicus

BACKGROUND

Lichen simplex chronicus is a dermatological condition due to excessive scratching, with few studies on psychoneuroimmunology.

OBJECTIVE

We aimed to estimate the levels of stress, depression, and anxiety, and to measure serum levels of neurotrophins in patients with lichen simplex chronicus, and to correlate these parameters with the severity of the disease and pruritus.

METHODS

Thirty-six patients with lichen simplex chronicus and 36 age- and sex-matched healthy controls were included. Each participant was administered the Hospital Anxiety and Depression Scale and Perceived Stress Scale questionnaires, along with a visual analog scale for pruritus. Levels of neurotrophins (brain-derived neurotrophic factor, neurotrophin-3, nerve growth factor, glial cell line-derived neurotrophic factor) were determined by ELISA assays.

RESULTS

The scores of Perceived Stress Scale-10, Hospital Anxiety and Depression Scale were statistically higher in patients (p < 0.05 for all). The serum levels of all neurotrophins were significantly lower in patients compared to healthy controls (p < 0.05 for all). Disease severity showed no correlation with all four neurotrophins. In linear regression models applied for increased visual analog scale-pruritus scores and disease severity these two variables were statistically significant predictors (p = 0.043).

STUDY LIMITATIONS

A direct causal relationship was not addressed.

CONCLUSION

Lichen simplex chronicus patients are at risk of increased levels of stress, anxiety, depression, and present decreased levels of neurotrophins, that may suggest a role in the pathophysiology of this disorder.

Assessment of Impairment of Quality of Life in Foot Eczema and Correlation thereof with Epidemiological Data of its Patients: A Cross-Sectional Study

Background:

Eczema of foot adversely impacts daily activities, work productivity, and interpersonal relationships.

Materials and Methods:

This cross-sectional, questionnaire-based study collated epidemiological data of 70 outpatients of foot eczema, evaluated their quality of life by 10-item dermatology life quality index (DLQI) questionnaire, and undertook the correlation thereof.

Results:

Cases were predominantly males (48; 68.5%); 26 (37.1%) belonged to fifth decade of life and 47 (67%) presented within 12 months of onset. Dorsa of feet was involved in most (59; 84.2%) cases. Itching was a universal complaint followed by scaling (51; 72.9%), dryness (22; 31.4%), and oozing (21; 30%). History of atopy was reported by 15 (21.4%) patients; tobacco and/or alcohol abuse 32 (45.7%) patients; past treatment was received by 37 (52.9%) patients; and winter aggravation in 9 (12.3%) patients. Mean DLQI score was 13.64; with very large effect (11–20) on QoL in 38 (54.3%) patients; moderate (6–10) in 15 (21.4%) patients; extremely large (21–30) in 9 (12.9%) patients; and small (2–5) in 8 (11.4%) patients. Mean scores of questions of DLQI tool were 2.46 in first question (symptoms), 1.99 in fifth (social activities); 1.81 in seventh (working/studying); and 0.17 in fourth (clothes) question. Significant (P < 0.05) impairment of quality of life emerged with respect of burning, scaling, oozing, history of atopy, seasonal variation, and past treatment.

Conclusion:

Our study reports significant association of atopy, winter aggravation, past treatment, burning, scaling, and oozing with adverse quality of life in our study on cases of foot eczema and appears to be first study from India.

Association of prurigo nodularis and lichen simplex chronicus with hospitalization for mental health disorders in US adults

Prurigo nodularis (PN) and lichen simplex chronicus (LSC) are debilitating chronic pruritic diseases that can lead to and be exacerbated by psychosocial distress. However, little is known about the mental health (MH) comorbidities of PN/LSC. We sought to evaluate the likelihood and cost-burden of MH comorbidities and emergencies associated with PN/LSC. Data were examined from the 2002-2012 Nationwide Inpatient Sample, including a representative ~ 20% sample of US hospitalizations (n = 87,053,155 admissions). Inpatients with vs. without PN/LSC had higher odds of MH disorders overall (39.4% vs. 20.0%; adjusted odds ratio [95% confidence interval, CI] 2.26 [2.13-2.41]) and in all 15 individual MH disorders examined. Inpatients with vs. without PN/LSC were more likely to be admitted with a primary diagnosis of a MH disorder (4.5% vs. 2.2%; 2.16 [1.91-2.45]), particularly developmental, psychotic, and mood disorders, history of MH disorders or substance abuse, and cognitive disorders. PN/LSC were associated with prolonged inpatient length of stay, and an excess $0.69 million in inpatient costs of care indirectly related to hospitalization for MH disorders. In conclusion, inpatients with PN/LSC had increased likelihood of comorbid MH disorders and emergencies requiring hospitalization. Optimized approaches are needed for screening and managing MH comorbidities in PN/LSC.
