RESUMO

Introduction: Follicular psoriasis is one of the underdiagnosed clinical types of psoriasis. Literature is grossly limited to anecdotal case reports and series. Clinical and investigational aspects are not studied in depth. Materials and Methods: A study was conducted to determine the frequency of follicular psoriasis, which includes cases with an exclusive or substantial number of follicular lesions. We analyzed the clinical, dermoscopic, and histopathological features of follicular psoriasis in a descriptive study. Results: A total of 117 patients with psoriasis were screened. An exclusive or substantial number of follicular lesions were found in 22 patients. Four patients had exclusively follicular lesions and others were psoriasis vulgaris with follicular psoriasis. Dermoscopy revealed perifollicular scaling and white homogeneous area with normal terminal hair in all cases. Vascular features were visible in 14 cases and all had dotted vessels, with four having additional globules. Twenty patients revealed one or more features suggestive of follicular psoriasis on histopathology. Conclusion: Follicular lesions can appear exclusively or can coexist with plaque type of lesions in psoriasis. They may indicate early psoriasis lesions. Dermoscopy is a useful and rapid tool to confirm the diagnosis of follicular psoriasis. Histopathology, though confirmatory, demands an astute interpretational skill. Diagnosis of follicular psoriasis can have therapeutic implications.

RESUMO

Psoriasis is a polygenic chronic skin condition, associated with many systemic disorders. Though it is most studied dermatological condition, molecular mechanism leading to its pathogenesis is still unclear. An insight into its proteome may help unrevealing some biomarkers and therapeutic targets. In this study, we carried out mass spectrometry based quantitative proteomic analysis of serum from psoriasis patients by employing Tandem Mass Tags (TMT) approach. We identified 861,887 MS/MS spectra corresponding to 493 proteins. These dysregulated proteins were further classified by Gene Ontology and protein-protein interaction of dys-regulated proteins revealed networks in psoriasis patients.

RESUMO

BACKGROUND: Onychomycosis is a very common disease and accounts for upto 50% of the diseases affecting the nail apparatus. Diagnosis of onychomycosis is usually confirmed with the help of a potassium hydroxide (KOH) mount and fungal culture. Onychoscopy can be a handy and additional tool for the diagnosis. AIMS AND OBJECTIVES: To determine the dermoscopic findings in distal lateral subungual onychomycosis (DLSO). MATERIALS AND METHODS: A prospective study of 60 nails with a clinical and mycological diagnosis (KOH with Chicago sky blue positive) of DLSO. Dermoscopic examination was performed using a Heine delta 20 plus dermatoscope and the features were recorded. RESULTS: Longitudinal striae and jagged proximal edges seen in all 60 (100%) patients. Intermittent spiked pattern was seen in 47 nails (78.3%). Chromonychia and distal irregular termination were noticed in 23 (38.3%) and 7 (11.7%) nails, respectively. CONCLUSIONS: Onychoscopy can be used as an important diagnostic tool while evaluating nail disease, especially in DLSO. LIMITATIONS: Small study sample and lack of comparison with other nail diseases that manifests with distal onycholysis.

RESUMO

BACKGROUND: Pemphigus and pemphigoid disorders produce blistering cutaneous lesions. Earlier case reports state that nail involvement is uncommon in these autoimmune blistering disorders. AIMS AND OBJECTIVES: To study nail changes in autoimmune blistering disorders. METHODS: A case-control study was conducted where 40 cases and 40 controls were evaluated for nail changes. RESULTS: Nail changes were seen in 72.5% of cases and 17.5% of controls. The most common nail findings were paronychia and onychorrhexis. LIMITATIONS: Small sample size; short study duration; nail biopsy could not be done. CONCLUSION: Our findings indicate that the inflammatory nature of the blistering cutaneous disease is often reflected conspicuously in the nails.

RESUMO

Dyslipidemias are one of the common metabolic disorders. A link between dermatological disorders like psoriasis and dyslipidemia has been established in the recent past. Many dermatological disorders could have a systemic inflammatory component which explains such association. Chronic inflammatory dermatological disorders could also have other metabolic imbalances that may contribute to dyslipidemia. Presence of such abnormal metabolism may justify routine screening of these disorders for associated dyslipidemia and other metabolic abnormalities and early treatment of such comorbidities to improve quality of life. Some of the drugs used by dermatologists such as retinoids are also likely to be a cause of dyslipidemia. Hence, it is imperative that the dermatologists obtain scientific knowledge on the underlying mechanisms involved in dyslipidemia and understand when to intervene with therapies. A systematic review of the English language literature was done by using Google Scholar and PubMed. In this review, attempts are made to list the dermatological disorders associated with dyslipidemia; to simplify the understanding of underlying mechanisms; and to give a brief idea about the interventions.
