The association of psoriasis and psoriatic arthritis with periodontitis: A hospital-based case-control study.

Background Periodontitis can trigger and perpetuate inflammation in several chronic inflammatory diseases. The association of periodontitis with psoriasis has been investigated earlier, but data are incomplete and the influence of confounders has not been fully evaluated. We examined the relationship of dental and periodontal health parameters in patients with psoriasis and/or psoriatic arthritis. Methods This hospital-based cross-sectional analytical study was conducted in patients with chronic plaque psoriasis, psoriatic arthritis or both, and compared with controls. Dental and periodontal health parameters were assessed based on the WHO oral health assessment method. Multivariate logistic regression was done on variables with significant or near-significant values to find the association between periodontitis and psoriasis and/or psoriatic arthritis after adjusting for confounders. Results Psoriasis and/or psoriatic arthritis were independently and significantly associated with periodontal pockets ≥4 mm in depth. Limitations Causality and temporal relationship cannot be established as this was a cross-sectional study. As in all observational studies, the possibility of unmeasured or unknown confounders exists. Psoriatic arthritis was present only in a small subset of patients. Conclusion Patients with psoriasis and/or psoriatic arthritis have significant periodontal inflammation. This needs to be addressed by dental examination and intervention.

Disseminated Kaposi's sarcoma as a presenting sign of HIV in an Indian male: A case report with dermoscopic findings.

Kaposi's sarcoma (KS) is one of the AIDS-defining illnesses, which tends to occur at low CD4 count. It is the most common malignancy associated with HIV disease. Yet, there is a paucity of Indian case reports of KS in the English literature. We report the case of a 45-year-old HIV-positive heterosexual male with an unusual presentation of KS in the form of unilateral lymphedema mimicking cellulitis. We also describe the dermoscopic findings of the same.

A Rare Case of Coexistence of Borderline Lepromatous Leprosy with Tuberculosis Verrucosa Cutis.

Occurrence of pulmonary tuberculosis with leprosy is known but association of cutaneous tuberculosis with leprosy is rare. We report a case of borderline lepromatous leprosy coexistent with tuberculosis verrucosa cutis in a 29-year-old male, who presented with multiple skin coloured nodules and hyperkeratotic scaly lesions of 3-month duration. Dual infections are associated with high mortality and morbidity. Therefore early diagnosis and management helps to reduce mortality and to mitigate the effects of morbidity.

Effect of antiretroviral therapy on mucocutaneous manifestations among Human Immunodeficiency Virus-infected patients in a tertiary care centre in South India.

BACKGROUND: Human Immunodeficiency Virus (HIV) infection produces a wide range of infectious and noninfectious dermatoses which correlate with the degree of immunodeficiency. Since the introduction of highly active antiretroviral therapy (HAART), there has been a dramatic decrease in the incidence of HIV-associated dermatoses. However, HAART itself causes various cutaneous adverse drug reactions. AIMS: To assess the various mucocutaneous manifestations in HIV-infected individuals and its association with CD4 count and to assess the effect of HAART on mucocutaneous manifestations. MATERIALS AND METHODS: Of the 170 patients recruited, 110 patients were previously diagnosed with HIV and were on follow-up. The rest 60 patients were newly diagnosed cases at recruitment, and these patients were followed up every month for mucocutaneous manifestations for a period of 6 months. RESULTS: Of the 170 patients screened, 69.41% patients had at least one mucocutaneous lesion at presentation. Fungal, viral, and bacterial infections were observed present in 17.6%, 10.6%, and 9.4% patients, respectively. There was a significant difference in the occurrence of candidal infections in the HAART versus non-HAART group (P = 0.0002). Candidiasis (P ≤ 0.0001) and human papillomavirus infection (P = 0.0475) occurred more commonly with CD4 count <200 cells/mm (3) . Among the noninfectious dermatoses, inflammatory dermatoses (17.6%) were more commonly observed at recruitment followed by adverse cutaneous drug reactions (16.5%) and neoplasms (5.3%). CONCLUSION: HAART has significantly altered the patterns of mucocutaneous manifestations. The prevalence of both infectious and inflammatory dermatoses has come down. However, there is an increase in the incidence of adverse cutaneous drug reactions.
