Acute laryngeal spasm

Parkinsonism associated with laryngeal spasm.

Laryngeal foreign body causing bronchial spasm.

Foreign bodies (FB) in the larynx and trachea usually lead to alarming circumstances, with death by complete obstruction of the respiratory tract as its utter consequence. Incidence rates are not high (2-11% of respiratory tract foreign bodies). Children from 6 months to 4 years of age are the most frequently affected, as expected due to their yet immature swallowing neuromuscular mechanism and...

Laryngeal Spasm Mimicking Asthma and Vitamin D Deficiency

We present a woman with heterozygous carnitine palmitoyl transferase 2 (CPT-2) deficiency who in the last 6 months suffered from episodic dyspnea and choking. Symptoms could not be attributed to her muscular energy defect, since heterozygous CPT-2 deficiency is usually asymptomatic or causes only mild muscle fatigability. Myopathy is usually triggered by concurrent factors, either genetic (addi...

Provoked coronary spasm and acute coronary syndromes.

lthough coronary artery spasm (CAS) has been linked ith acute coronary syndromes (ACS) and vulnerable laque (1), thrombosis (2), percutaneous coronary intervenion (PCI), and stenting (3–7), very limited attention is iven to CAS in the current era. This may be related to ssumptions that the frequency of CAS is decreasing and if resent it will be eliminated with calcium antagonist (8) or itrate u...
