A family suffered carbon monoxide toxicity, with cerebral and / or cardiac complications, while sleeping in the cabin on a recreational boat. This article describes a couple exposed to a malfunctioning air-conditioning system on the boat, which subsequently developed the unique combination of cerebral symptoms and a non Q/non-ST elevation myocardial infarction, with enzyme elevations and electrocardiographic abnormalities. This interesting complication of a myocardial infarction secondary to carbon monoxide toxicity, associated with neurological manifestations, is reviewed.

We report a male patient who after a fall suffered high cervical spinal cord and head (cerebral) injuries. These injuries led to spinal shock, marked sinus bradycardia and asystolic cardiac and respiratory arrests, recalcitrant central traumatic diabetes insipidus, and death within approximately seven weeks. Temporary transvenous cardiac pacing proved useful in the management of this patient.

OBJECTIVES: To examine the utility of a risk-approach model in identifying infants at greater risk of postneonatal mortality (PNM) and to determine whether there is a relationship between PNM and linkage of at-risk infants to primary health care. METHODS: The Sheffield Birth Score instrument was applied to 90,846 newborn infants to determine high-score (HS) and low-score (LS) infant risk groups. Health care visit data were collected on all HS infants who were referred for primary pediatric care. Mortality rates were calculated for both HS and LS infant groups and for HS infants who were linked and not linked to care. RESULTS: The HS infant group was at significantly greater risk of PNM (p < 0.0001). The linked group had a lower PNM rate (p < 0.05), and linked/not-linked group differences were noted for 11 of 20 variables. When these 11 variables and the linked/not-linked variable were entered into a logistic regression analysis, linkage was the only significant variable (p < 0.01) in predicting PNM. CONCLUSIONS: The Sheffield Birth Score differentiated at birth those infants who were at greater risk of PNM. The lower incidence of PNM among linked HS infants suggests a promising argument for early pediatric intervention. Further research to clarify specific factors that influence health care participation decisions is suggested.

Carbamazepine, a drug used for the treatment of epilepsy and neuralgias, may exert hazardous effects on the cardiac conduction system. We report such a case of symptomatic brady-arrhythmia occurring in a 43-years-old male while on therapy with carbamazepine. Additionally, a literature review is made of previous cases of carbamazepine-induced sinus mode, AV node and His-Purkinje conduction disturbances.

A case of the relatively rare atrial parasystole is reported, and this interesting cardiac arrhythmia is reviewed. Atypical deviations from classical parasystole are reviewed, and modern concepts of parasystole as they differ from traditional, classical parasystole are addressed

Pacemaker atrial lead dislodgement inducing ventricular pacing is reviewed, and four such observed cases are described. This interesting complication of the atrial lead producing ventricular depolarization results in an array of electrocardiographic manifestations and vignettes. These documented experiences emphasize the infrequent persistence of this event, even with the utilization of modern atrial passive and active fixation leads.

This article documents the rare, possibly coincidental, association of the Marfan and the Wolff-Parkinson-White syndromes. However, an as yet unproven, hypothetical link of a connective tissue, mesenchymal and embryologic, developmental dysplasia, offers a provocative nosological connection.

This communication describes a patient with Down's syndrome, in whom an Ebstein's anomaly of the tricuspid valve was found at autopsy. The association of these two conditions appears to be rare.
