A Case of Congenital Nephrogenic Diabetes Insipidus with Bilateral Hydronephrosis and Hydroureter / 대한신장학회잡지

We describe a case of congenital nephrogenic diabetes insipidus with severe dilatation of bilateral urinary tracts without anatomical obstructions. Functional obstruction can be occurred when polyuria surpasses the transporting ability of urine in the urinary tract. The patient was admitted to our hospital due to decreased mentality developed after traffic accident. On radiologic study, bilateral hydronephrosis and hydroureter were noted. Because the patient excreted copious dilute urine, we performed water deprivation test and the result was consistent with nephrogenic diabetes insipidus. We are presenting this case in an attempt to describe strong association between congenital diabetes insipidus and nonobstructive hydronephrosis in which polyuria is responsible for the hydronephrosis.

A Case of Abdominal Actinomycosis Developed in Upper Gastrointestinal Tract / 대한소화기내시경학회지

Actinomycosis is a rare chronic suppurative disease caused by actinomyces species, which are normal flora in the oral cavity and gastrointestinal tract, and characterized by formation of sulfur granule. Actinomyces can affect cervicofacial, pulmonary, abdominal and pelvic area. However, abdominal and pelvic inflammations are less frequently observed. Most of abdominal actinomycosis develop after abdominal operation, trauma, inflammatory bowel disease or use of intrauterine devices. The definitive diagnosis was made after histopathological study of the tissues. Treatment is long-term antibiotic therapy. Herein, we report a case of a 69-year-old woman with an unusual form of abdominal actinomycosis after total gastrectomy.
