Breath-Hold Diving-Related Decompression Sickness with Brain Involvement: From Neuroimaging to Pathophysiology.

Central nervous system involvement related to decompression sickness (DCS) is a very rare complication of breath-hold diving. So far, it has been postulated that repeated dives with short surface intervals represent a key factor in the development of breath-holding-related DCS. We report the case of a breath-hold diver who, after repeated immersion, developed DCS with brain involvement.

An unique case suffering from repetitive syncope episodes due to ictal asystole.

We present the case of a patient with syncope with repetition over 12 years, with a clinical profile not clearly related with a cardiogenic origin, who was studied by several medical specialties without any accurate diagnosis. After subcutaneous loop recorder implantation, we were able to demonstrate how seizures acted as a trigger in the genesis of an exaggerated cardio inhibitory reflex. A new entity has been described, known as "ictal asystole", in patients with focal epilepsy mostly from the temporal lobes and has been implicated as a cardiac cause of sudden unexplained death in epilepsy.
