We report a case of a man with erythrocytosis secondary to hydronephrosis in a right horseshoe kidney. The patient had an advanced hydronephrosis because of ureteropelvic junction obstruction occupying the right hemiabdomen. Following nephrectomy of the right kidney erythrocyte count returned to normal values. Secondary polyglobulia may be due to increased erythropoietine values and has been related in some patients with renal diseases such as hydronephrosis, but very rarely in association with hydronephrotic horseshoe kidney.
We report two cases of pulmonary BCG-induced pneumonitis recently diagnosed amongst our patients. The first case is a 81 year old man under BCG bladder instillation treatment because of high grade superficial bladder cancer who developed a severe interstitial granulomatous pneumonitis. The patient was treated with corticosteroids and tuberculostatics with a rapid and complete response. The second patient is a young man who presented only with persistent fever and also had a complete response after treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
