COVID-19 caused by SARS-CoV-2 may present with a wide spectrum of symptoms ranging from mild upper respiratory tract infection like illness to severe pneumonia and death. Patients may have severe hypoxaemia without proportional features of respiratory distress, also known as ‘silent’ or ‘apathetic’ hypoxia. We present a case of a 56-year-old man with COVID-19 who presented to the fever clinic of our institution with fever and cough without any respiratory distress but low oxygen saturation. The patient deteriorated over the next 2 days but eventually recovered of his illness in due course of time. This case demonstrates ‘silent hypoxia’ as a possible presentation in COVID-19 and emphasises the importance of meticulous clinical examination including oxygen saturation measurements in suspected or confirmed patients.

The Greek score appears as the single best score. Using the newly developed discriminant cut off value; a substantial number of patients may be started with anti-platelet therapy while awaiting CT scan of brain.

We report two novel fluorescent probes viz.BPQ1 and BPQ2, to detect selectively cysteine (Cys) in dual reporter mode based upon the specific position of the reactive acrylate group.

Rowell’s syndrome is a rare disorder characterised by an association of lupus erythematosus with erythema multiforme (EM)-like skin lesions. EM as the initial clinical presentation of systemic lupus erythematosus is also atypical and even rarer. We report the case of an 18-year-old girl admitted to our hospital with fever and polyarthralgia along with multiple discrete ill-defined target lesions with crust formation over forehead, cheek, external ears, scalp, upper chest and back (predominantly over sun-exposed areas) with ulceration over hard palate. Investigations revealed pancytopaenia, a positive rheumatoid factor, positive antinuclear antibody with a speckled pattern, anti-Smith antibody and strongly positive anti-Ro. Patient was diagnosed with Rowell’s syndrome as per clinical and laboratory features. Majority of skin lesions including oral ulcerations subsided gradually after treatment with steroids and hydroxychloroquine.
