A ranula is a mucus retention cyst or pseudocyst caused by leakage of mucus from the sublingual gland and generally occurs in the oral floor. In addition, drug induced hypersensitivity syndrome (DIHS) is a rare but well-recognized serious adverse effect characterized by fever, skin rashes, generalized lymphadenopathy, hepatitis, and hepatosplenomegaly and oral stomatitis. This paper presents th...

INTRODUCTION Allopurinol hypersensitivity syndrome is an idiosyncratic drug reaction characterised by an acute and severe multiorgan disease. It usually begins 2 to 6 weeks after starting allopurinol. The most important and critical characteristics are the presence of visceral involvement and haematological abnormalities; hepatitis, interstitial nephritis and eosinophilia are most frequently se...

Trichloroethylene is commonly used as an industrial solvent and degreasing agent. The clinical features of acute and chronic intoxication with trichloroethylene are well-known and have been described in many reports, but hypersensitivity syndrome caused by trichloroethylene is rarely encountered. For managing patients with trichloroethylene hypersensitivity syndrome, avoiding trichloroethylene ...

ADRs: adverse drug reactions LTT: lymphocyte transformation test MDH: multiple drug hypersensitivity MDHS: multiple drug hypersensitivity syndrome MP: Mycoplasma pneumoniae PA: particle agglutination SJS/TEN: Stevens-Johnson syndrome/toxic epidermal necrolysis Tregs: regulatory T cells INTRODUCTION Many adverse drug reactions (ADRs), including Stevens-Johnson syndrome (SJS)/toxic epidermal necr...

Ticagrelor is widely used to treat acute coronary syndrome. Hypersensitivity reaction of ticagrelor is rarely recognized. A low response to clopidogrel, which occurs in up to 23% of patients, is an independent risk factor for stent thrombosis. Management of patients with a low response to clopidogrel and ticagrelor hypersensitivity who are undergoing antithrombotic therapy remains to be a chall...

We thank the many women who completed questionnaires for this study. We are grateful to the staff at the collaborating breast screening units and at the Million Women Study coordinating centre for their valuable contribution to the study and to Adrian Goodill for producing the figure. Contributors: Emily Banks, Gillian Reeves, Valerie Beral, and Julietta Patnick had the original idea for the st...

Drug hypersensitivity with myocarditis is known to occur with many drugs especially with antiepileptics, sulpha-compounds and daposne. Dapsone (4, 4 diaminodiphenyl sulphone) induced hypersensitivity is known to occur in about 2% of leprosy patients on treatment and an incidence of 1.66% in non-leprosy patients. We report this rare case of dapsone hypersensitivity syndrome in a girl on dapsone ...

Cough is an intrinsic protective reflex. However, chronic cough affects a considerable proportion of general population and has a major impact on quality of life. A recent paradigm shift to 'cough hypersensitivity syndrome' suggests that chronic cough arises from hypersensitivity of the airway sensory nerves. As cough reflex is determined by interaction of the nervous system with immune system,...
