Coronary-artery Calcium Scores Using Electron Beam CT in Patients with Chronic Renal Failure
We evaluated the risk of coronary-artery disease in patients with chronic renal failure (CRF) by measuring the coronary-artery calcium scores with electron beam CT (EBCT). A total of 81 CRF patients were divided into three groups; pre-dialysis (group I, n=35), hemodialysis (group II, n=31) and peritoneal dialysis (group III, n=15). The several serum biochemical markers and calcium score levels by EBCT were determined. The Ca×P products were significantly higher in groups II (p<0.05) and III (p<0.01) than in group I. The serum calcium levels were significantly higher in group III than in both group I (p<0.01) and II (p<0.05). The serum calcium level in 15 patients with a calcium score > 400 was significantly higher than the 66 patients with a score ≤400 (p<0.01). The calcium score was significantly higher in the 15 patients with cardiovascular complications than in the 66 patients without cardiovascular complications (628.9±904.8 vs. 150.4±350.9, p<0.01). EBCT seemed to be a good diagnostic tool for evaluating the risk of coronary-artery disease "non-invasively" in CRF patients who are at increased risk of cardiovascular morbidity and mortality
Progression of coronary artery calcification and cardiac events in patients with chronic renal disease not receiving dialysis
We tested for the presence of coronary calcifications in patients with chronic renal disease not on dialysis and studied its progression in 181 consecutive non-dialyzed patients who were followed for a median of 745 days. Coronary calcifications (calcium score) were tallied in Agatston units by computed tomography, and the patients were stratified into two groups by their baseline calcium score (100 U or less and over 100 U). Survival was measured by baseline calcium score and its progression. Cardiac death and myocardial infarction occurred in 29 patients and were significantly more frequent in those patients with calcium scores over 100 U (hazard ratio of 4.11). With a calcium score of 100 U or less, the hazard ratio for cardiac events was 0.41 and 3.26 in patients with absent and accelerated progression, respectively. Thus, in non-dialyzed patients, the extent of coronary calcifications was associated to cardiac events, and progression was an independent predictive factor of cardiac events mainly in less calcified patients. Hence, assessment of coronary calcifications and progression might be useful for earlier management of risk factors and guiding decisions for prevention of cardiac events in this patient population

Abdominal Cerebrospinal Fluid Pseudocyst Diagnosed with Point-of-care Ultrasound
Abdominal pseudocysts are rare complications of ventriculoperitoneal (VP) shunts characterized by accumulations of cerebrospinal fluid surrounded by fibrous layers in the intra-abdominal cavity or abdominal wall. We present a woman with bilateral VP shunts who presented with right-sided abdominal distension, pain, and tenderness and who was found to have an abdominal pseudocyst on point-of-care ultrasound and computed tomography. Given the potential to develop a secondary infection or VP shunt malfunction, it is important for emergency providers to consider intra-abdominal complications of VP shunts, including rare ones such as abdominal pseudocysts, in these patients who present with vague abdominal complaints
