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.

Xanthogranulomatous pyelonephritis in childhood is a rare chronic pyelonephritis often assodiated with calculi of urinary tract obstruction, with a clinical presentation of renal mass. A 3-year old boy was admitted to Korea University Hospital complaining of intermittent fever and palpable mass at right upper quadrant of the abdomen. The CBC revealed increased ESR and the finding of iron deficientcy anemia. Proteus mirabilis was cultured from the urine. We found the idiopathic hypercalciuria was affected also. Intravenous pyelogram. ultrasonogram and abdominal computerized tomogrhapy demonstrated a multiple cystic lesion with renal calculi at upper and lower pole of right kidney. Right nephrectomy was performed under the suspicion of the renal abscess with renal stone. Postoperatively microscopic examination revealed parenchymal destruction with infiltration of foamy phagocytes, giant cells, and plasma cells. In conclusion, we experienced a case of xanthogranulomatous pyelonephritis with idiopathic hypercalciuria in a child. So, we report it with a review of literature.

Lipoprotein(a) [Lp(a)] is considered an additional, independent and largely genetically determined risk factor for the development of premature coronary heart disease. Furthermore abnormal plasma lipoprotein patterns have been associated with increased risk for developing coronary heart disease. Among these lipoproteins, an increased concentration of serum Apo B and decreased level of Apo A are considered as major risk factors. together with elevated serum cholesterol and decreased HDL cholesterol. The aim of this study is to assess serum Lp(a) levels in newborns and to observe their evolution between brith, 7 days and 1 month in 64 healthy newborns by using ELISA method, Other lipid profiles were also measured and compared with feeding formula methods. The results obtained were as follows: 1) There were no significant changes from birth to 7 days, but was increased significantly after 7 days to 1 month of serum Lp(a) concentrations. 2) There were dramatic increases between birth and 7 days for Apo B and did not change between 7 days and 1 month, while Apo A-I was already present in significant levels at birth and was changed continuously between 7 days and 1 month. 3) There were marked increases between birth and 7 days for total cholesterol and triglycerides, while after 7 days the cholesterol levels only progressively increased until month. 4) There were continuous increases between birth and 7 days and 1 month for HDL-C, while LDL-C was markedly increased between birth and 7 days. 5) There were no significant correlations between serum Lp(a)concentrations and other lipid profiles neither age, sex and feeding formulas. In conclusion, our data suggest that the adequate timing for the screening test of Lp(a) in newborns is around 1 month after birth and there are no statistically significant correlations between Lp(a) and other lipid profiles.

OBJECTIVE: The purpose of this study was to investigate psychological impacts of infertility-related stress in Korean infertile women. METHODS: Both the 34 infertile women group and the control group(34 married women) were evaluated by using Semistructured Questionnaire, Stress Perception Scale, Coping Behavior checklist, Beck Depression Inventory(BDI), Hamilton Anxiety Scale(HAS), Hamilton Rating Scale for Depression(HRSD), SCL-90-R and State Trait Anxiety Inventory(STAI). RESULTS: Perceived financial stress, frequency of negative and neutral life events and frequency of passive coping(especially, emotion-focused coping) were significantly higher in infertile women than control group. In infertile women, totally perceived stress was positively correlated with BDI, SCL-90-R(depression) and STAI. Passive coping behavior was positively correlated with BDI, HAS and STAI. CONCLUSION: Above results suggest that infertile women would have a tendency to passive coping and high level of depression and anxiety, and should be considered for psychiatric intervention.

BACKGROUND: The authors performed this study to investigate the hemodynamic effect of nicardipine using an esophageal Doppler monitor (EDM) during gynecologic laparoscopic surgery. METHODS: Forty patients scheduled to undergo gynecologic laparoscopic surgery, were divided into two groups; the control group (Group C) and the nicardipine group (Group N). Pneumoperitoneum was initiated using CO2 gas and the intraperitoneal pressure was kept under 12 mmHg. Hemodynamic parameters at critical points were measured using EDM, i.e., before skin incision (T1), 5, 10 and 15 min after the initiation of pneumoperitoneum (T2, T3 and T4), and 5 min after deflation (T5). RESULTS: Mean arterial pressure (MAP) was significantly lower in Group N patients than in Group C patients at 5 and 10 min after the initiation of pneumoperitoneum (T2 and T3) (P < 0.05). No significant heart rate (HR) differences were observed between the two study groups. Cardiac output (CO), peak velocity (PV) and corrected flow time (FTC) were significantly higher in Group N at 10 min after the initiation of pneumoperitoneum (T3) (all P < 0.05). CONCLUSIONS: The nicardipine continuous infusion at 0.5?2.0microg/ kg/min is effective at attenuating hemodynamic changes after pneumoperitoneum during gynecologic laparoscopic surgery.

A clinical and laboratory study was conducted on 58 children who had been admitted to out pediatric department from February to September 1979, under the clinical diagnosis of septicemia. Following results were obtained: 1. Boys were affected more frequently than girls(1.3:1), and highest incidence was noticed in newborn period, comprising 50% of the total cases. 2. The common clinical manifestations, in order of frequency, were fever, lethargy, jandice, poor sucking and abdominal distension, and hyperbilirubionemia was the most common assocaited disease, followed by anemia and leukemia. 3. Clinical course revealed death in 6 patients(10.3%), discharge against advice in 7cases(21.1%) and complete recovery in the remaining 45 cases(77.6%). 4. Peripheral blood count showed leukocytosie in 40%, leukopenia in 12.1% and thrombocytopenia was seen in 45% of cases. 5. Gram staining of buffy coat smear showed bacteria in 34.5% and especially high ratio was noticed in newborn infants(48.3%). 6. Positive blood culture was seen in 39.7% with highest ratio of 45% in newborn infants. In positive blood culture group, toxic granules were noted in 32.8%, shift to left in 25.9%, hrombocytopenia in 18.9% and positive buffy coat smear in 15.5%. In summary, thrombocytopenia, toxic granules, shift to left were quite helpful in early diagnosis of sepsis. In addition to diagnostic value, examination of buffy coat smear could aid physician to select appropriate antibiotic regimen especially in sepsis of newborn period.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, and cystic changes are commonly observed. However, there have been few reports of cases of exophytic pedunculated GIST with cystic changes. Here, we report a 45-year-old man who presented with a palpable mass in the left upper quadrant of the abdomen. The mucosal folds were endoscopically abnormal, but there was no mucosal lesion. Computed tomography demonstrated a large, low-density cystic lesion surrounding an enhanced nodule in the greater curvature of the gastric body, and there was no tumor infiltration to other organs. The patient underwent hemigastrectomy and the lesion was shown to be an exophytic pedunculated cystic tumor. Histopathological examination showed epithelioid cells with marked hemorrhaging. Immunohistochemical examination indicated that most of the tumor cell cytoplasm was positive for the c-kit protein (CD117) and CD34. The tumor was diagnosed as an exophytic pedunculated GIST of the stomach with cystic changes.
