A case of nephrogenic diabetes insipidus caused by partial bilateral ureteral obstruction due to advanced stage ovarian carcinoma.

Nephrogenic diabetes insipidus (NDI) secondary to chronic urinary tract obstruction is a rare condition. The exact cause is unknown; it is likely that increased collecting duct pressures cause damage to the tubular epithelium, resulting in insensitivity to the antidiuretic hormone (ADH). We report a case of NDI associated with ureteral obstruction caused by advanced stage ovarian carcioma in a 20-year-old girl.

Plasma homocysteine, vitamin B12 and folate levels in hydatidiform moles and histopathological subtypes.

Objective: To investigate the association of mole hydatidiform with plasma homocysteine, vitamin B(12), and folate levels.

Methods: Sixty-eight patients diagnosed with mole hydatidiform at our clinic between February and October 2007 were assessed in a case-control study. Plasma homocysteine, vitamin B12, and folate levels, taken before evacuation of patients with hydatidiform mole, were compared with the results of 100 healthy normal pregnants of first trimester; and also plasma homocysteine, vitamin B12, and folate levels were compared according to histopathological types of mole hydatidiforms.
