Efficacy and Safety during the Combination Therapy of Imipramine and Desmopressin in Primary Monosymptomatic Nocturnal Enuresis

PURPOSE: Nocternal enuresis is a common disorder. Tricyclic antidepressant and desmopressin have been accepted pharmacological treatment for this disorder. We conducted a cooperative study to investigate the efficacy and adverse reactions of imipramine, desmopressin and combination treatment in children with primary monosymptomatic nocturnal enuresis(PMNE). METHODS: Data from a large multicenter study were analysed. In the period of 8 months in 2002, the study comprised of 168 children(78 boys and 90 girls, 5 to 15 years old) with PMNE for imipramine, desmopressin or combination treatment. Before treatment a history, physical examination and laboratory tests were performed and the children were observed for 2 weeks. Response rate, adverse reactions and enuresis episodes after stopping drug administration were evaluated after 12-weeks of imipramine, desmopressin or combination of both. RESULTS: After 4 weeks, the frequency of bed wetting in all treated patients decreased during treatment significantly. Even though a 30-50% reduction in the number of wet nights were 68.6%, 74.4% and 86.1% during 12 weeks treatment by imipramine, desmopressin and both of them respectively, there was no significant difference between them. The most common adverse reaction was decreased appetite from imipramine administration. But no serious drug-related adverse events were reported. CONCLUSION: Efficacy of the combination therapy of imipramine and desmopressin in PMNE appears not to be better than either drug alone. It is necessary to pay attention on account of adverse reactions during imipramine treatment even though imipramine and desmopressin were generally well tolerated.

Effects of Dietary Protein on the Progression of Early Chronic Renal Failure in Subtotally Nephrectomizid Rets

Endodermal sinus tumor of the mediastinum is a very rare malignant tumor, usually affecting young adolescents, and its histologic findings are characteristic as that of gonadal germ cell origin. We describe the cytologic finding of fine needle aspiration of mediastinal endodermal sinus tumor in a 19-year-old male patient, comparing with tissue section. The tumor cells in smears were usually in tight clusters with large overlapping cells, which were arranged in a papillary or microacinar pattern, suggesting carcinoma. The tumor cells were large, round or oval with a small amount of cytoplasm which was occasionally vacuolated and had indistinct border. The nuclei were large, pleomorphic, and vesicular with large promi- nent nucleoli. The tissue sections showed typical findings of endodermal sinus tumor. Careful correlation of cytological findings and the serum alpha-fetoprotein level would be helpful to confirm the diagnosis.

Effects of Dietary Salt Restriction in the Development of Renal Failure in the Excision Remnant Kidney Model

So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells having pre- dominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei, The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchioloalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.

Significance of Acute Phase Reactants (APR) Score for the Early Detection of Neonatal Bacterial Infection

PURPOSE: We performed acute phase reactants (APR) test to evaluate as an appropriate screening test for the early detection of neonatal bacterial infection. METHODS: We selected 174 neonates and divided into two groups; sepsis group and well-baby group. We performed APR test. RESULTS: There are no significant difference in total leukocyte count, immature to mature rentrophil ratio, toxic granules, and platelet count between two groups. Number over two and one point of APR score in group I were significantly high compared to group II. Over two point and one point of APR score in neonatal infection had sensitivity of 58.7% and 92.3%, respectively the specificity of 95.7% and 70.0%, respectively Twenty-four cases of three point and 37 cases of two point of APR score were proved neonatal sepsis. Twenty-eight cases of over two point of APR score were positive in blood culture. CONCLUSION: APR score could be regarded as an useful test method for early detection of neonatal bacterial infection.

Renal Effects of a Low Protein Diet and Antihypertensive Drugs on the Progression of Early Chronic Renal Failure in 5/6 Nephrectomized-Rats

A case of invasive cribriform carcinoma of the breast is presented with fine need- le aspiration cytologic features. The aspiration was performed from a papable 2.0cm mass in the upper outer quadrant of the right breast in a 53 year-old woman. The aspirate showed cellular smear composed of larger three dimensional tight clusters, smaller monolayered loose clusters, and many individual cells on the clean background. In the clusters, the tumor cells were bordering central lumina, quite similar to the cribriform in histology. The tumor cells in the clusters and individual tumor cells had uniform, small and round nuclei. The chromatin was finely granular, and nuclear membrane was smooth. No discernible nucleoli were present (nuclear grade 1-2). Unless the abundance of individual cells and the cribriform growth pattern are recognized in the smear, the cytologic diagnosis of invasive cribriform carcinoma is difficult.
