Chronic Kidney Disease in Patients with Psoriasis -A Hospital Based Cross Sectional Study.

Background: Psoriasis is a multi-system inflammatory disease where skin and joints are the primary targets. Recently, some studies had shown the association of psoriasis with kidney disease.

Aims: To study the association of psoriasis with chronic kidney disease (CKD) in a tertiary health care center.

Comparison of High Resolution Ultrasonography with Clinical Examination in the Assessment of Peripheral Nerve Involvement in Leprosy.

Context: Assessment of peripheral nerves in leprosy by clinical methods is subject to considerable inter-observer variability. High resolution ultrasonography (HRUS) can assess peripheral nerves more objectively.

Aims: To compare the findings of peripheral nerve involvement in newly diagnosed cases of leprosy by clinical and sonological methods.

Methotrexate iontophoresis versus coal tar ointment in palmoplantar psoriasis: A pilot study.

Background: Palmoplantar psoriasis is often disabling and refractory to conventional therapy. Systemic drugs are indicated in its severe form, but side effects are a concern with their use. Methotrexate is one such systemic drug which is effective and cheap.

Spontaneous regression in an ulcerated CK7 positive Merkel cell carcinoma.

Merkel cell carcinoma is an aggressive and frequently lethal tumor of the elderly, associated with sun exposure and immunosuppression which is less common in the dark-skinned. We report the case of a 40-year-old woman who presented with multiple slowly progressive, mildly itchy ulcerated plaques of size ranging from 2 × 3 cm to 5 × 7 cm on the left knee of 1 year duration. Skin biopsy showed diffuse dermal infiltration by small round cells with molding of cells and lymphocyte infiltration.

Frequency and management of respiratory incidents in invasive home ventilation.

There has been a rise in the number of patients requiring long-term ventilation, both in the in-hospital and the out-of-hospital setting. Despite this, little is known about the subsequent clinical course of these patients following hospital discharge. The purpose of this study was to determine the frequency and management of respiratory incidents in patients with invasive out-of-hospital ventilation living in a nursing home allied to a weaning centre.

Syphilis of Fungal world: Novel Skin Manifestations of Histoplasmosis in an Immunocompetent Host.

A case of chronic disseminated cutaneous histoplasmosis with unusual skin manifestations in an immunocompetent host is reported. Presence of cutaneous ulcers, linear erythematous plaques, skin coloured atrophic plaques and recurrent self-limiting oral ulcers in a single patient has not been documented in literature so far. Diagnosis was established by identifying small intracellular yeast-like cells of Histoplasma in tissue smear and skin biopsy.

Postpartum pemphigoid gestationis.

Pemphigoid gestationis (PG) or herpes gestationis is a rare autoimmune subepidermal blistering disorder associated with pregnancy. The condition typically develops during the second or third trimester of pregnancy, but has been rarely reported in the first trimester and postpartum period. Here, we report a case of PG that presented for the first time in the postpartum period, associated with a low birth weight baby.

Localized psoriasis herpeticum: Case report and review of literature.

Kaposi's varicelliform eruption (KVE) is a widespread cutaneous eruption caused by viruses, especially herpes simplex virus in patients with pre-existing dermatoses. "Psoriasis herpeticum" refers to the rare occurrence of KVE in patients with psoriasis. We report a case of KVE localized to the face in a patient with exfoliative dermatitis secondary to psoriasis.

Purpuric macules with vesiculobullous lesions: a novel manifestation of Chikungunya.

Background: Chikungunya (CHIK) is an emerging viral disease with a myriad of cutaneous manifestations.

Aims: The aim of our study was to document the morphology and evolution of skin lesions in cases presenting with fever, purpuric macules and vesiculobullous lesions, to confirm its causative relationship with CHIK, and to investigate further in order to delineate possible mechanisms of bulla formation in these cases.

Materials And Methods: A prospective, descriptive hospital-based study was carried out at a tertiary health care centre in Kerala.

Sub-polar lepromatous leprosy localized to the face.

Leprosy is an infectious disease characterized by a wide spectrum of clinical manifestations, ranging from tuberculoid to lepromatous disease with immunologically unstable borderline forms in between. In clinical practice cases often do not conform to a classical textbook description, which may lead to misdiagnosis if not properly investigated. A 22-year-old patient presented to us with erythematous plaques localized to the face.

Carbamazepine--the commonest cause of toxic epidermal necrolysis and Stevens-Johnson syndrome: a study of 7 years.

Background: Toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS) are a group of severe life threatening drug reactions. The drugs commonly implicated as the cause of these drug reactions vary depending on host factors and the prescription pattern of drugs in that particular area.

Aim: The aim of the study was to find the drugs implicated as the cause of SJS/TEN in the patients admitted in the dermatology ward at the Medical College, Thrissur and to find the clinical outcome.

Activation of the interferon-alpha pathway identifies a subgroup of systemic lupus erythematosus patients with distinct serologic features and active disease.

Objective: Gene-expression studies have demonstrated increased expression of interferon (IFN)-inducible genes (IFIGs) in peripheral blood mononuclear cells (PBMCs) of many patients with systemic lupus erythematosus (SLE), with a predominant effect of type I IFN. This study examined the hypothesis that increased disease severity and activity, as well as distinct autoantibody specificities, characterize SLE patients with activation of the type I IFN pathway.

Methods: Freshly isolated PBMCs from 77 SLE patients, 22 disease controls, and 28 healthy donors were subjected to real-time polymerase chain reaction for 3 IFIGs that are preferentially induced by IFNalpha, and the data were used to derive IFNalpha scores for all individuals.

Coordinate overexpression of interferon-alpha-induced genes in systemic lupus erythematosus.

Objective: To study the contribution of interferon-alpha (IFNalpha) and IFNgamma to the IFN gene expression signature that has been observed in microarray screens of peripheral blood mononuclear cells (PBMCs) from patients with systemic lupus erythematosus (SLE).

Methods: Quantitative real-time polymerase chain reaction analysis of healthy control PBMCs was used to determine the relative induction of a panel of IFN-inducible genes (IFIGs) by IFNalpha and IFNgamma. PBMCs from 77 SLE patients were compared with those from 22 disease controls and 28 healthy donors for expression of IFIGs.
