Atopic dermatitis and association of risk for primary immune thrombocytopenia and autoimmune diseases among children: A nationwide population-based cohort study

Allergic Contact Dermatitis, Angioneurotic Edema and Conjunctivitis in a Patient with Autoimmune Thrombocytopenia - A Clinical Case

BACKGROUND

Allergic contact dermatitis (ACD) is common in clinical practice, but the aetiology of this disease is quite varied. A leading pathogenetic mechanism is a cell-mediated immunity. The combinations of ACD with other allergic and systemic autoimmune diseases are relatively rare, but these conditions are undoubtedly a professional challenge for practitioners.

CASE REPORT

We present a case of ACD combined with other immune-allergic conditions. Aetiology and pathogenesis in these cases are not well understood.

CONCLUSION

Based on the data from the general and targeted allergic history, patient's subjective complaints, clinical picture, allergenic status, paraclinical results, and the presented photo material, the final diagnosis is as follows: Contact allergic dermatitis-acute form.

Associations of self-reported allergic diseases and musculoskeletal problems in children: A US population-based study

BACKGROUND

Previous studies have found increased rates of musculoskeletal problems in adults with allergic disease, but whether this association holds true for children is unknown.

OBJECTIVE

To investigate the association of bone, joint, and muscle problems in children with a history of allergic disease.

METHODS

Data were obtained from the 2007 Child and Adolescent Health Measurement Initiative. Univariable and multivariable logistic regression models accounting for the sampling design were used to evaluate associations of bone, joint, and muscle problems with allergic diseases, such as asthma, hay fever, food allergies, and eczema. Associations were summarized with odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS

The survey included 91,642 individuals aged 0 to 17 years. Multivariable modeling found statistically significant associations between the number of allergic diseases and bone, joint, and muscle problems (1 allergic disease: adjusted OR, 1.28; 95% CI, 1.04-1.56; P = .02; 2 allergic diseases: adjusted OR, 2.55; 95% CI, 1.92-3.39; P < .001; 3 allergic diseases: adjusted OR, 2.70; 95% CI, 1.88-3.86; P < .001; and 4 allergic diseases: adjusted OR, 4.35; 95% CI, 2.46-7.69; P < .001). Severe eczema (but not mild eczema) was associated with bone, joint, and muscle problems (adjusted OR, 2.81; 95% CI, 1.64-4.81; P < .001) and with bone problems (adjusted OR, 6.08; 95% CI, 1.94-19.12; P = .002).

CONCLUSION

Self-reported allergic diseases in children were associated with bone, joint, and muscle problems, and associations strengthened with allergic disease severity and number of allergic diseases. Severe eczema may be associated with bone problems in children. Bone, joint, and muscle problems must be considered in children with severe allergic disease, and prospective studies are necessary to define this association.

"Inflammatory skin march" in atopic dermatitis and psoriasis

BACKGROUND

Comorbidities of cardiovascular diseases (CVDs), metabolic syndrome and autoimmune diseases with systemic inflammation are recent topics in medicine. Inflammatory skin diseases such as atopic dermatitis and psoriasis are an active source of diverse proinflammatory cytokines and chemokines, which are readily detectable in the circulation and are likely to be involved in developing comorbidities.

EVIDENCE

Both atopic dermatitis and psoriasis are frequently comorbid with CVD, metabolic syndrome and autoimmune diseases, the consequence of which is called "inflammatory skin march", "psoriatic march" or "march of psoriasis".

CONCLUSION

In this review, we summarize the epidemiological evidence and pathogenetic concepts regarding inflammatory skin march in atopic dermatitis and psoriasis.

Risk of sudden sensorineural hearing loss in stroke patients: A 5-year nationwide investigation of 44,460 patients

Poststroke sudden sensorineural hearing loss (SSNHL) can hinder communication between patients and healthcare professionals, thereby restricting participation in rehabilitation programs and limiting improvements in physical performance. However, the relationship between stroke and SSNHL remains unclear. This study employed a nationwide population-based dataset to investigate the relationship between stroke and SSNHL.The Taiwan Longitudinal Health Insurance Database was used to compile data from 11,115 stroke patients and a comparison cohort of 33,345 matched nonstroke enrollees. Each patient was followed for 5 years to identify new-onset SSNHL. Stratified Cox proportional-hazard regression analysis was used to examine the association of stroke with subsequent SSNHL.Among the 44,460 patients, 66 patients (55,378 person-years) from the stroke cohort and 105 patients (166,586 person-years) from the comparison cohort were diagnosed with SSNHL. The incidence of SSNHL was approximately twice as high among stroke patients than among nonstroke patients (1.19 and 0.63/1000 person-years, respectively). Stroke patients had a 71% increased risk of SSNHL, compared with nonstroke patients (adjusted hazard ratio [HR] 1.71, 95% confidence interval [CI] 1.24-2.36). We also observed a remarkable increase in risk of SSNHL in stroke patients within 1-year of follow-up (adjusted HR 5.65, 95% CI 3.07-10.41) or under steroid therapy during hospitalization (adjusted HR 5.14, 95% CI 2.08-12.75).Patients with stroke had a higher risk of subsequent SSNHL compared with patients without stroke. In particular, stroke patients within 1-year follow-up and those undergoing steroid therapy during hospitalization should be treated with the utmost caution, considering that the risk of SSNHL increases by more than 5-fold.
