Removal of Ciprofloxacin and Norfloxacin from Aqueous Solution with Activated Carbon from Cupuaçu () Bark.

The widespread use of antibiotics such as fluoroquinolones (FQs) has raised environmental and health concerns. This study is innovative as we investigate the removal of ciprofloxacin (CIP) and norfloxacin (NOR) from water using activated carbon derived from cupuaçu bark (CAC). This previously discarded biomass is now a low-cost raw material for the production of activated carbon, boosting the local economy.

A case of adult granulosa cell tumor of the testis.

Background: Adult granulosa cell tumors of the testis (AGCTT) are classified as sex cord-stromal tumors. Only 31 cases have been reported. Typical presentation includes a slowly enlarging, painless testicular mass.

Postcoital Hemorrhage of a Recurrent Seminal Vesicle Cyst Requiring Embolization.

Herein is a case of a 23-year-old man with recurrence of a seminal vesicle cyst after percutaneous drainage and laparoscopic excision complicated by hemorrhage requiring embolization. He presented to the emergency department for pain after ejaculation. Computed tomographic scan of his pelvis revealed extravasation of contrast near his cyst and pelvic fluid collection suspicious for a hematoma.

The association between statin medication and progression after surgery for localized renal cell carcinoma.

Purpose: Evidence suggests that statins may influence pathways of renal cell carcinoma proliferation, although to our knowledge no study has examined the influence of statin medications on the progression of renal cell carcinoma in humans.

Materials And Methods: We identified 2,608 patients with localized renal cell carcinoma who were treated surgically between 1995 and 2010 at our tertiary referral center. Competing risks Cox proportional hazards models were used to evaluate the relationship between statin use and time to local recurrence or progression (metastases or death from renal cell carcinoma) and overall survival.

Recovery of a catalase-negative Staphylococcus epidermidis strain in blood and urine cultures from a patient with pyelonephritis.

This report describes a 60-year-old patient with bilateral nephrolithiasis. A catalase-negative Staphylococcus epidermidis strain was recovered from both urine and blood cultures. Although rare, isolates of catalase-negative Staphylococcus spp.
