ALOPECIA AREATA AND AUTOIMMUNITY: A CLINICAL STUDY

Alopecia areata (AA) frequently occur in association with other autoimmune diseases such as thyroid disorders, anemias and other skin disorders with autoimmune etiology. Despite numerous studies related to individual disease associations in alopecia areata, there is paucity of literature regarding comprehensive studies on concomitant cutaneous and systemic diseases. The present study has been designed to determine if there is a significant association between alopecia areata and other autoimmune diseases. This study covers 71 patients with the diagnosis of alopecia areata as the case group and 71 patients with no evidence of alopecia areata as the control group. Among the cutaneous diseases associated with AA, atopic dermatitis (AD) showed maximum frequency with an O/E ratio of 2.5, which indicates that it is two to three times more common in patients with alopecia areata. In our study, thyroid disorders showed the highest frequency with on O/E ratio of 3.2 and a P value of 0.01, which is statistically highly significant. Among the thyroid disorders, hypothyroidism was the most frequent association (14.1%) in our study. Since systemic involvement is not infrequent in patients with alopecia areata, it is imperative to screen these patients for associated disorders, particularly atopy, thyroid diseases, anemias and other autoimmune disorders, especially if alopecia areata is chronic, recurrent and extensive.

Mucocutaneous manifestations of Dengue fever.

Dengue viral infection is a cause of considerable morbidity and mortality and may be associated with a variety of mucocutaneous manifestations that may provide important early clues to the diagnosis of this condition. Cutaneous and mucosal findings like confluent erythema, morbilliform eruptions, and hemorrhagic lesions may figure prominently in the clinical features of dengue. The differential diagnoses include a large number of bacterial and viral exanthems as well as drug rash.

Aplasia Cutis Congenita with Ectopic Mongolian Spot in a Child of a Patient of Multiple Sclerosis: A Rare Case Report

Aplasia cutis congenita (ACC) is a rare heterogenous disorder which is characterized by focal absence of skin since birth. Underlying structures such as bone or dura may also be involved. ACC has been considered to be a forme fruste of a neural tube defect by many authors. It might occur in isolation or in association with certain syndromes. We report a case of a new born male with membranous type of ACC over vertex extending to the left parietal region with partial agenesis of parietal bone and ectopic mongolian spot over left ankle.

New onset bullous lupus erythematosus in a systemic lupus erythematosus patient after initiation of hydroxychloroquin

We report a case of a 14-year-old Indian girl, a diagnosed case of systemic lupus erythematosus (SLE) who developed generalized erythematous rash and joints pain for 15 days. She was prescribed hydroxychloroquin and low dose deflazacort for joint pains. Within 3 days of initiation of hydroxychloroquin she developed generalized eruptions in the form of tense, fluid-filled blisters, erosions, and crusting. Biopsy showed subepidermal blistering with a prominent neutrophilic infiltrate. Direct immunofluorescence (DIF) showed positive granular immunoglobulin (Ig)G deposition with C3 and C1q at the dermoepidermal junction which was consistent with bullous SLE (BSLE). The lesions responded dramatically to dapsone 100 mg daily.
