Imperforate hymen is, with an incidence of 0.1%, a rare female anomaly, which can appear with symptoms such as lower abdominal pain, primary amenorrhea, dysuria, anuria, caused by retention of menstrual blood after the onset of menstruation. Generally urinary retention is caused by psychological conditions, drug effect, infection or congenital anomaly causing acute urinary obstruction. We experienced a patient with symptoms of acute urinary retention, suggesting acute urinary obstruction. The cause for the retention turned out to be an imperforated hymen, which should therefore be mentioned in the literature as a possible cause in cases suspected of urinary retention.

PURPOSE: Early diagnosis and treatment of febrile urinary tract infection (UTI) in children is important to prevent kidney damage. This study aims to evaluate the relationship between the presence of pyuria, the severity, and underlying genitourinary anomalies in patients with UTI. METHODS: We retrospectively reviewed 293 patients with febrile UTI who were admitted to Korea University Guro Hospital during the period from June, 2007 until January, 2010. We divided the patients into two groups, one with the finding of pyuria at admission, and the other without, and compared the fever duration, white blood cell counts (WBC) and C-reactive protein (CRP) in peripheral bloods, hydronephrosis, cortical defects, vesicoureteral reflux and admission period. RESULTS: Among the 293 patients with febrile UTI, 189 patients showed findings of pyuria whereas 104 patients did not. Patients with pyuria showed an increment of WBC (14,694+/-485.2 vs. 11,374+/-451.2/uL, P<0.05) and CRP (46.9+/-3.9 vs 17.1+/-3.6 mg/L, P<0.05) in peripheral blood sample. The presence of cortical defects (21.7 Vs 5.8%, P<0.05) and vesicoureteral reflux (15.9 Vs 6.7%, P<0.05) was also increased in patients with pyuria compared to patients without pyuria. There were no specific differences in fever duration, admission period, and hydronephrosis. Within the group with pyuria, CRP in peripheral blood sample increased proportionally with the increment of pyuria (P<0.05). CONCLUSION: In patients with febrile UTI, the increment of WBC in the urine sample can be a helpful predictor for increased CRP in peripheral blood and acute pyelonephritis.

PURPOSE: Some hormonal and electrolyte abnormalities have been reported in pediatric patients with urinary tract infection (UTI). This study aimed to investigate the relationships between the imbalance of electrolytes and the severity of infection and associated urologic anomalies in children with febrile UTI. METHODS: We retrospectively reviewed 267 patients with febrile UTI who were admitted to Korea University Guro Hospital during the period from January, 2007 until February, 2010. According to the presence of hyponatremia or hyperkalemia, clinical parameters and associated renal anomalies, such as hydronephrosis, cortical defects and vesicoureteral reflux, were compared. RESULTS: 42.7% of all patients had decreased concentration of serum sodium. In patients with decreased concentration of serum sodium, cortical defects were significantly increased compared to normal patients (40.4% vs. 14.4%, P<0.05). White blood cell (WBC) counts (15,721+/-6,553/uL vs. 12,885+/-5,367/uL, P<0.05), C-reactive protein (CRP) (61.8+/-56.1 mg/L, vs. 29.9+/-39.8 mg/L, P<0.05), and erythrocyte sedimentation rate (ESR) (43.9+/-34.3 mm/hr vs. 27.4+/-26.8 mm/hr, P<0.05) in peripheral blood showed significant increases in the group with decreased concentration of serum sodium. Duration of fever, presence of gastrointestinal symptom, the incidence of hydronephrosis and vesicoureteral reflux did not differ between the two groups. None of the patients had significant hyperkalemia. CONCLUSION: We suggest that decreased concentration of serum sodium in febrile UTI might be a helpful marker for leukocytosis and increased CRP and ESR in peripheral blood, and acute pyelonephritis.

Purpose: To assess characteristics the application of mobile medication system and medication administration error (MAE) alerts in a general hospital. Methods: The subject hospital adopted a mobile medication system in 2016. All medication administrations in the general wards and ICUs were automatically recorded in real-time using identification barcodes, drug barcodes, and hand-held point-of-care devices. MAE alert logs were recorded from April 1st 2017 to March 31st 2018. For this study analysis was done using Pearson’s chi-squared test for potentially related factors of MAE alerts included administration time, order type, medication route, and length of nurse’s employment. Results: The total number of medications during the period of this study was 3,227,990. Among them, 2,698,317 medication doses were recorded, resulting in the system application rate of 83.6%. The system application rate was significantly correlated with all factors related to potential MAE alters. In this study 23,314 MAE alerts(0.9% of the total medication doses) were identified. The MAE alerts were related to new (OR=2.26, p<.001) and emergency (OR=2.25, p<.001) orders, and administration at a non-standard time (OR=2.032, p<.001). Medication route (p<.001), and nurse’s employment duration(p<.001) were also related. Conclusion A mobile medication system contributes to improving patient safety by preventing potential MAEs. The MAE alerts were related to administration time, order type, medication route, and duration of nurse’s employment. In order to prevent medication administration errors, it is necessary to standardize the process of medication and create an environment in which medication administration can be performed in a planned situation.

We report herein a case of subclavian steal syndrome due to occlusive disease in multiple branches of the aortic arch, which was successfully treated by axilloaxillary bypass and subclavian stent insertion. The hemodynamic changes were evaluated using duplex sonography and transcranial Doppler before and after each procedure. The waveform and parameters of blood flow revealed an objective improvement in cerebral perfusion. These findings correlated well with clinical outcome. Neurosonologic evaluation can provide objective evidence for improved hemodynamic status after treatment.
