Polyethylene glycol (PEG)-3350 is the most frequently used lavage solution for bowel cleansing prior to colonoscopy or elective surgery because its large molecular weight means that it is poorly absorbed. However, if it leaks into the peritoneal cavity, complications may arise. Few published studies have assessed the absorption, distribution, metabolism and excretion of PEG. Moreover, no published clinical data regarding complications due to the intra-peritoneal leakage of PEG-3350 could be found. We report on an elderly patient who developed the poisoning caused by leaking of PEG-3350 during bowel preparation. It resulted in severe metabolic acidosis, hypernatremia, hyperosmolality and a high anion gap, but it was effectively treated with early continuous renal replacement therapy after surgery.

BACKGROUND: Clinical and experimental studies have suggested that brain death may cause hemodynamic, electrocardiographic, functional or histopathologic changes of the heart. METHODS: Brain death was induced by increasing intracranial pressure(ICP) abruptly by intermittent bolus injection of saline(model ) or gradually by continuous infusion of saline(model ) to the epidural catheter in 5 mongrel dogs, respectively. Hemodynamic and biochemical changes during the process of brain death and histopathologic changes of the myocardium were analyzed and compared in two brain death models, and the association of apoptosis was also evaluated. RESULTS: 1) Two predominant subsets of acute contraction band lesion were produced in both brain death models : paradiscal and holocystic contraction band lesions. Both contraction band lesions were more prevalent in brain death model . 2) The frequency of both contraction band lesions was lowest in the epicardial layer and highest in the endocardial layer in both models, but no correlation was observed between the degree of contraction band lesions and ICP, LV maximum +dp/dt or catecholamine levels. There was no statistical difference between any of the LV circumferential blocks and either type of contraction band lesion, and transaxial distribution was not also different in both models. 3) There was no remarkable histopathologic changes in the analysis of major epicardial coronary arteries. Apoptotic cells were suggested in the scattered myocytes in the light microscopy and apoptosis was detected by in situ nick end labeling method. Electron microscopy revealed a condensation of nuclear chromatin and convolution of nuclear membrane in those myocytes. CONCLUSIONS: Myocardial changes due to brain were observed frequently, and few apoptotic cells were found in the brain death heart. Studies on the treatment strategy to minimize damages of myocardial structure and function caused by brain death should be followed in the near future.

The frequent occurrence of hematuria in children necessitates diagnostic evaluation. Hematuria may occur with either renal or lower urinary tract disease. Clarification of the etiology of hematuria, whether microscopic or gross, is facilited by localizing the site of bleeding to the kidney (glomerular) or the lower urinary tract (non-glomerular). The mean cellular volume (MCV) of urinary red blood cells (RBCs) of pediatric patients with glomerular (group I; n=77) and non-glomerular (group II; n=34) hematuria was determined using Coulter Counter Model S plus IV. We found that re blood cells of glomerular origin had a smaller volume than non-glomerular cells(73.79 9.75 m3 vs 83.55 3.77 m3, p<0.001). If an urinary MCV equal to 80.56 m3 was taken as the cut-off value between glomerular and non-glomerular hematuria, a correct assessment of the site of bleeding was made in 89 (80%) of the 111 patients studied (sensitivity 76%, specificity 88%). The ratio of the urinary erythrocyte MCV to that in blood(Umcv/Bmcv) was compared with the diagnosis. If an Umcv/Bmcv ratio equal to 0.95 was taken as the cut-off value between glomerular and non-glomerular hematuria, a correct assessment of the site of bleeding was made in 93 (83%) of the 111 patients studied (sensitivity 79.6%, specificity 94%). Coulter counter analysis of urine provides a simple noninvasive and objective aid to the diagnosis of hematurai. This test, when used early in the management of pediatric patients with hematuria, may help to avoid invasive investigations.

The congenital cystic adenomatoid malformation (CCMA) of the lung is a rare variant of congenital cystic lung disease consisted of one or usually multiple interconnecting cysts in the pulmonary parenchyma lined by cuboidal and columnar epithelium. This diease present clinically in three ways: 1) stillborn or perinatal death, 2)progress respiratory distress in the newborn, and 3)acute and chronic pulmonary infections in the older infant and child. The onset of symptoms, which are cyanosis, tachypnea, and other forms of respiratory distress, usually occurs at or shortly after birth, This manifestations are related to compression of the remained normal ung by expansion of the cysts. We have experienced a case of congenital cystic adenomatoid malformation of the lung in a 1-day-old male infant who had tachypnea. A right upper lobectomy was done with satisfactory postoperative courses clinically and radiologically at 8 months of age. A brief review of the related literature is presented.

Lung agensis is a rare developmental anomaly. It can range from total bronchial and parechymal agensis to mild pulmonary parenchymal hypoplasia of one or both lungs. A case of lobar agenesis of the left upper lung in a 15-year-old boy is presented. The patient had mild exertional dyspnea. Pulmonary angiography revealed the absence of the left upper pulmonary artery and vein. Bronchography showed no branching of bronchus to the left upper lobe. Intravenous pyelography revealed incomplete duplication of the right urinary tract.
