Similar to other autoimmune diseases, its pathogenesis is believed to be an interaction of genetic, environmental and immune factors. Studies have shown that autoreactive lymphocytes affect anagen hair follicles leading to subsequent shedding of hairs and alopecia. Clinically, the disease is characterized by sudden nonscarring hair loss that usually involves the scalp, but may also affect the face and other body areas, and indeed the entire body hair. AA may appear for the first time at any age, affecting both children and adults, but it occurs primarily at a young age with a peak incidence in the second and third decade of life. The disease causes pronounced social and psychological impact. The main therapeutic approaches include immunosuppression through anti-inflammatory agents and immunomodulation based on skin sensitization.

Laboratory confirmation of fungal infection is currently accepted as a requirement before initiation of antifungal treatment in clinical practice. To examine the rationale for systemic treatment in cases of clinical onychomycosis with negative results on fungal examination (potassium hydroxide test and fungal culture). In total, 147 patients with suspected clinical toenail onychomycosis but with negative results on fungal examination underwent up to three consecutive fungal examinations of the affected nails. Patients who were negative after these examinations underwent a fourth set of investigations, including PCR. Of the 147 cases initially thought to be negative, 138 (94%) were rated as positive after up to four consecutive sets of laboratory mycological investigations including PCR. Trichophyton rubrum was by far the commonest dermatophyte cultured from all samples. In the majority of cases of initially negative examinations, consecutive laboratory fungal tests will eventually produce positive results. These findings suggest that systemic antifungal treatment should be started in patients with suspected fungal infections, even if they have negative laboratory fungal examinations.

Data on the pathophysiology and treatment of pCIA are scarce. We describe a patient who developed pCIA after hematopoietic stem cell transplantation and responded to low-dose oral minoxidil (LDOM) with full hair regrowth.

The aims of this study were to determine the prevalence and spectrum of malignancy in patients with bullous pemphigoid and to compare demographic, clinical, therapeutic and outcome data between bullous pemphigoid patients with and without malignancy. This retrospective cohort study enrolled 335 patients (194 women and 141 men; mean age at diagnosis of bullous pemphigoid 77.5 ± 12 years) followed up at an Israeli tertiary centre between January 2009 and December 2019: 107 (32%) had malignancy and 228 (68%) did not. Malignancy occurred before and after bullous pemphigoid diagnosis in 82 (77%) and 25 (23%) patients, respectively. Bullous pemphigoid patients with cancer were older (p = 0.02) and had a higher mortality rate (p < 0.0001) than those without malignancy. The 2 groups did not differ in terms of sex, comorbidities, or clinical characteristics. Those who...

This study aimed to investigate the correlation between the neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, platelet-to-neutrophil ratio, mean platelet volume, and disease activity in patients with pemphigus vulgaris. <b><i>Methods:</i></b> Fifty-six patients (20 men, 36 women; mean age 54 ± 14 years) diagnosed with pemphigus vulgaris were included in this retrospective study. Patients were divided into those treated and not treated with rituximab (groups 1 and 2), and into those who did and did not develop relapse (groups 3 and 4). The neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, platelet-to-neutrophil ratio and mean platelet volume were evaluated at the time of diagnosis, remission, and relapse. The relationship between each marker and disease stage was analyzed using the Wilcoxon rank-sum test for pairwise comparisons. <b><i>Results:</i></b> The neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio showed a positive correlation with disease activity, while the platelet-to-neutrophil ratio and mean platelet volume showed a negative correlation. The neutrophil-to-lymphocyte ratio significantly decreased in remission (<i>p</i> &lt; 0.001) and significantly increased in relapse (<i>p</i> &lt; 0.01). The platelet-to-lymphocyte ratio significantly decreased in remission (<i>p</i> &lt; 0.001) and showed no significant change in relapse. The platelet-to-neutrophil ratio significantly increased in remission (<i>p</i> &lt; 0.001) and significantly decreased at relapse (<i>p</i> &lt; 0.001). The mean platelet volume significantly increased in remission (<i>p</i> &lt; 0.001) and decreased non-significantly at relapse. A more significant decrease in the neutrophil-to-lymphocyte ratio in remission was found in patients not treated with rituximab. No significant differences wer [...]

Although several studies have investigated the epidemiology, clinical characteristics and treatment of AA, limited recent data are available regarding its long‐term course.ObjectivesTo evaluate the long‐term course of AA in different age groups.MethodsA retrospective evaluation of patients who were newly diagnosed with AA from 2008 to 2011 and had at least 7 years of follow‐up. Data regarding the initial episode, treatment given, disease‐free interval and relapses were analysed.ResultsA total of 104 cases were analysed: 31 childhood‐onset, 63 adult‐onset and 10 late‐onset. At first episode, 88.5% of patients had mild, 3.8% moderate and 7.7% severe AA. Full or significant re‐growth was observed in 74%, 94% and 100% of childhood‐onset, adult‐onset and late‐onset AA patients, respectively. There was no re‐growth in 13%, 3% and 0% of childhood‐onset, adult‐onset and late‐onset pa...
