Transient Loss

In acute carbon monoxide intoxication the presence of altered consciousness, ranging from transient loss of consciousness to coma, represents a poor prognostic factor and modifies the approach to therapy. Transient loss of consciousness is, as a rule, contemporaneous to the exposure, generally occurring at the scene of the intoxication. We report an unusual case of delayed transient loss of consciousness, occurring in the absence of any other evident aetiology, in one member of an orchestra composed of 110 members after a mass carbon monoxide poisoning.

The differential diagnosis of an episode of transient loss of consciousness can be sometimes very tricking, in particular when symptoms peculiar of syncope are mixed with focal neurological symptoms. We report the case of a 54-year-old woman who suddenly claimed, during a polygraphic recording (electroencephalography/electrocardiogram), a feeling of fear and tachycardia followed by loss of consciousness and then a tonic posturing of the left limbs. Polygraphic recording showed a critical electroencephalographic pattern starting from left temporo-zygomatic channels followed after few seconds by a sudden slowing of cortical background activity associated with an episode of asystole, as witnessed simultaneously by electrocardiogram. Muscular activity covered electroencephalographic activity of following minutes. This case provides an opportunity to highlight the existence of rare conditions such as ictal arrhythmias which should be considered in the differential diagnosis of episodes of transient loss of consciousness in particular when dysautonomic and neurological symptoms are intermingled. Autonomic symptoms (vomiting, tachycardia, cyanosis, bradycardia and asystole) may be also more frequent in idiopathic (more rarely symptomatic) epilepsies of childhood (Panayiotopoulos syndrome).

Carbon monoxide poisoning is the leading cause of mortality and morbidity of toxic origin in the world. Its insidious and polymorphic symptomatology makes it difficult to diagnose. It occurs accidentally, because of non-supervised domestic fires, or in fire victims. In fire victims, in particular, the differential diagnosis between carbon monoxide gas poisoning, inhalation of other toxic products of combustion like cyanide, oxygen deprivation, thermal burns and shock due to burns as a cause of death is not an easy task. The authors examined 107 fire victims that were autopsied at the Forensic Medicine from Iasi, Romania, in the last 10 years (2007-2016). Most cases were males (69.16%), young (0-9 years) or older than 60 with a burned surface of 91-100% in 68.22% of cases. Blood samples from the cadavers were collected in all cases in order to analyse carboxyhaemoglobin concentration and haemolysis. Toxicological analysis revealed a carboxyhaemoglobin level of maximum 95% but the majority of cases (70.72%) had a concentration inferior to 50%. An inverse correlation was identified between carboxyhaemoglobin concentration and haemolysis, an indicator of heat dissociation. Our study proves that many fire victims may die because of carbon monoxide intoxication prior to the extent of burns at a lethal potential.

Diagnostic Investigations

The recommendations enclosed in the present document have been developed by a group of experts appointed by the <em>Gruppo Multidisciplinare per lo Studio della Sincope</em> (Multidisciplinary Group for the Study of Syncope; GIMSI) and Academy of Emergency Medicine and Care (AcEMC). The aim is to define the diagnostic pathway and the management of patients referred to the Emergency Department (ED) for transient loss of consciousness of suspected syncopal cause, which is still unexplained after the initial evaluation. The risk stratification enables the physician to admit, discharge or monitor shortly the patient in the intensive short-stay Syncope Observation Unit (SOU). There are three risk levels of life-threatening events or serious complications (low, moderate, high). Low risk patients can be discharged, while high risk ones should be monitored and treated properly in case of worsening. Moderate risk patients should undergo clinical and instrumental monitoring in SOU, inside the ED. In all these three cases, patients can be subsequently referred to the Syncope Unit for further diagnostic investigations.

Abstract: A 52-year-old woman is presented with repetitive transient loss of consciousness. Implantable loop recorder (ILR) recorded muscle artifacts during the generalized tonic-clonic seizures. Seizure was diagnosed and antiepileptic drug was started. The patient has been asymptomatic for 9 months. Orv Hetil. 2019; 160(29): 1143–1145.
