Zoster Sine Herpete: two unusual cases of varicella-zoster reactivation with atypical complaints of acute chest pain and severe headache.

In this case report, we describe two unusual presentations of varicella-zoster virus (VZV) reactivation without rash, a condition known as Zoster Sine Herpete (ZSH). In Case 1, a 58-year-old woman presented with severe right-sided chest pain under her breast that radiated to the ipsilateral back. After the initial workup ruled out cardiac and musculoskeletal etiologies, the characteristic dermatomal distribution of pain made us suspect VZV reactivation.

Burden And Spectrum Of Respiratory Ailments In Paediatric Tertiary Care Setting.

Obesity And Diabetes As Determinants Of Vitamin D Deficiency.

Background: Vitamin D has been the focus of attention in the recent past owing to its multitude of effects on various organ systems including immune system, endocrine, cardiovascular etc. Diabetes mellitus and obesity are widely prevalent in our region. The present study was designed with an objective to determine the vitamin D status in relation to diabetes mellitus and obesity in our area.

Spironolactone-induced degradation of the TFIIH core complex XPB subunit suppresses NF-κB and AP-1 signalling.

Aims: Spironolactone (SPL) improves endothelial dysfunction and survival in heart failure. Immune modulation, including poorly understood mineralocorticoid receptor (MR)-independent effects of SPL might contribute to these benefits and possibly be useful in other inflammatory cardiovascular diseases such as pulmonary arterial hypertension.

Methods And Results: Using human embryonic kidney cells (HEK 293) expressing specific nuclear receptors, SPL suppressed NF-κB and AP-1 reporter activity independent of MR and other recognized nuclear receptor partners.

Corneal Complications And Visual Impairment In Vernal Keratoconjunctivitis Patients.
