Hereditary angioedema with normal C1 inhibitor

Wolf in the sheep's clothing: intestinal angioedema mimicking infectious colitis

Hereditary angioedema (HAE) is a relatively rare clinical entity that can potentially cause life-threatening airway or intestinal oedema, patients with the latter usually presents with symptoms of gastroenteritis like vomiting, diarrhoea and abdominal pain. Here, we present a unique case of a less recognised type of HAE that is type III in a patient who presented with signs and symptoms consistent with infectious colitis. She previously had similar episodes and was managed multiple times with antibiotics, with no satisfactory response. There, she underwent extensive diagnostic evaluation. On the basis of findings of further investigations on the current visit, she was eventually diagnosed with intestinal angioedema. To the best of our knowledge, the present paper represents the third reported case of type III HAE-induced intestinal angioedema. Additionally, we undertake a literature review of HAE.

Acute allergic angioedema of upper lip

Mishaps can occur during dental procedures, some owing to inattention to detail and others are totally unpredictable. They usually include anaphylaxis or allergic reactions to materials used for restorative purposes or drugs such as local anesthetics. A patient reported to our department with moderate dental fluorosis, and the treatment was planned with indirect composite veneering. During the procedure while cementation acute allergic reaction occurred, the specific cause could not be identified after allergic testing. During the procedure while cementationacute allergic angioedema of upper lip. Anaphylaxis, urticaria, allergy, hereditary atopic eczema, cellulitis, cheilitis granulomatosa, and cheilitis glandularis. The patient was reassured and given prednisolone 10 mg and cetirizine 10 mg orally, once daily for 3 days after which the symptoms subsided. This paper will discuss the pathogenesis, classification, identification, and management of angioedema during dental procedures.

Repeated angioedema following administration of venlafaxine and mirtazapine

We report a rare case of a 48-year-old female who presented with bilateral lower-leg swelling due to a medication-induced angioedema resulting from the use of two common classes of antidepressants, venlafaxine and mirtazapine. Although the mechanisms by which the antidepressants achieve these effects are not understood, the recent recognition of a novel antidepressant-dependent form of angioedema may offer important insights into the mechanisms by which the antidepressants exert their effects.
