This case report discusses a rare occurrence of type II Kounis syndrome, characterised by an acute myocardial infarction triggered by an allergic reaction. The patient, a young adult male, experienced urticaria soon after eating oysters, which quickly escalated to severe chest discomfort. Despite lacking typical cardiac risk factors, the electrocardiogram showed indications of ST-elevation myocardial infarction. This condition was further complicated by ventricular fibrillation, necessitating urgent life-saving measures. This case demonstrates the intricate and often overlooked relationship between hypersensitivity reactions and cardiovascular events. It highlights the necessity for increased vigilance and rapid diagnostic and treatment approaches in handling Kounis Syndrome, especially in emergency situations. The case underscores the importance of considering allergic causes in acute cardiac scenarios, particularly in patients who do not have standard risk factors for coronary artery disease.

Pseudoterranoviasis is a zoonotic disease caused by nematode larvae of species within the genus Pseudoterranova (seal worm, cod worm). Most infections are gastrointestinal, oesophageal or pharyngeal, but here we report a nasal infection. A 33-year-old patient suffering from rhinitis for 1.5 years recovered a worm larva from the nose. Diagnosis was performed by morphological and molecular characterization, showing the causative agent to be a third-stage larva of Pseudoterranova decipiens (sensu stricto). Various infection routes are discussed.

A 57-year-old female patient with a diagnosis of schizo-affective disorder since 1986 was commenced on clozapine due to persistent positive and negative psychotic symptoms in September 2014. After commencement of clozapine she was delusion free and demonstrated an improvement in negative symptoms. Three months after commencement of clozapine she developed a hypersensitivity reaction. Her symptoms continued to deteriorate despite being prescribed an anti-histamine. Clozapine was discontinued 6 days after the appearance of a generalised pruritic rash, as it was believed to be the probable cause. There was complete resolution of symptoms 1 week after discontinuation of clozapine. Clozapine was replaced with olanzapine and amisulpride. There has been no similar cutaneous or allergic reactions for the past 30 months.
