Cardiac arrest: abdominal CT imaging features.

We report computed tomographic findings of two unusual cases of sudden cardiac arrest. The imaging features documented include reflux of contrast into the abdomen as indicated by opacification of renal veins, hepatic veins, inferior vena cava, and hepatic and renal parenchyma. The reflux of contrast into the portal vein in one patient has not been described in the literature. The thoracic findings were reflux of contrast into the coronary sinus, nonopacificaton of the left ventricle with intravenous contrast, and lack of cardiac motion artifact.

The Erve virus: possible mode of transmission and reservoir.

The Erve virus is suspected to cause severe headache in humans, lasting several days (thunderclap headache). Mice are characterized as a probable reservoir for the Erve virus. We tested 396 wild mice for Erve virus using an immunofluorescence test and found Erve virus antibodies in five cases, showing that small mammals form a reservoir for Erve virus. If ticks are the vector for the virus, a coincidence with borreliosis should exist. We were unable to confirm this in a homogeneous cohort of 955 young men, 62 of whom tested positive for borreliosis. This group did not test positive significantly more often in the immunofluorescence test than a gender- and age-matched control group.

Unusual case of postoperative infection caused by Morganella morganii.

Morganella morganii is a facultative Gram-negative anaerobe present in the human gastrointestinal system as normal flora. Clinically, the organism is important when it manifests as an opportunistic pathogenic infection elsewhere in the body. This paper reviews an unusual case in which M. morganii is the pathogen responsible for a devastating postoperative infection in a diabetic patient. Currently, there are no known reported cases in the literature of M. morganii as an etiologic pathogen for a postoperative foot infection. Prompt diagnosis and treatment of this organism is imperative to reduce the patient's overall morbidity and mortality.

Hydropericardium causing sudden infant death in glycogenosis type I: osmotic injury due to percutaneous silastic catheterization.

BACKGROUND: The aim of this case report and the review of the literature is to demonstrate dangers when using peripherial silastic catheters in preterm and term newborns or infants. PATIENT, METHODS AND RESULTS: We report on a female infant with glycogenosis type I a (MIM 232200) due to glucose 6-phosphatase deficiency (homozygosity for R170X) and sudden infant death at the age of 9 months due to a rare catheter complication (hydropericardium with tamponade without perforation). CONCLUSION: We believe that this fatal complication was caused by local osmotic dysbalance due to direct contacts between atrial wall and the catheter tip. There is no relation known between patients with inborn errors of metabolism complicated by metabolic derangement and higher incidences of mechanical or non-mechanical catheter complications.

Early phosphorus 31 nuclear magnetic resonance bioenergetic changes potentially predict rejection in heterotopic cardiac allografts.

The development of a noninvasive screening test for the detection of cardiac allograft rejection would improve the potential for management of heart transplant recipients. To assess the possibility that changes in myocardial high-energy phosphate metabolism precede frank rejection, 17 beagles received cervical cardiac allografts. Recipients underwent serial phosphorus 31 nuclear magnetic resonance spectroscopy, endocardial biopsy (blindly graded, 0 to 8), and left ventricular pressure measurements starting on the day of surgery. The first (less than 24 hours) spectrum was considered the baseline for all additional studies. The phosphocreatine to inorganic phosphate ratio (PCr/Pi), an index of myocardial bioenergetic supply/demand balance, was determined and expressed as a percentage of baseline of initial and all subsequent spectra. To evaluate the predictive utility of the PCr/Pi ratio, a 50% decrease from baseline was designated as a positive test and was correlated with biopsy-proved rejection (score greater than 3). When PCr/Pi values were compared with the subsequent day's biopsy score, we observed a 91% sensitivity, 90% specificity, and a predictive value of 92%. We conclude that the PCr/Pi ratio is sensitive in predicting heterotopic allograft rejection in its earliest stages. Thus phosphorus 31 nuclear magnetic resonance holds promise for clinical use in the noninvasive diagnosis and monitoring of cardiac rejection.
