Effects of grain adaptation programs and antimicrobial feed additives on performance and nutrient digestibility of cattle fed whole shelled corn.

Two experiments were conducted to evaluate the effects of feed additives [monensin (); 30 mg/kg of dry matter (), and virginiamycin (); 25 mg/kg DM] and grain adaptation programs [adding roughage (; sugarcane bagasse) or not () during the 20-d adaptation period] on performance, carcass characteristics, and nutrient digestibility of cattle fed finishing diets containing 85% whole shelled corn and 15% of a pelleted protein-mineral-vitamin supplement. In Exp.1, 105 Nellore bulls [initial body weight () = 368 ± 25 kg] were used in a complete randomized block design with a 2 × 2 factorial arrangement of treatments, consisting of two feed additives (MON and VM) associated with two adaptation programs (ROU or NO-ROU during the 20-d adaptation period).

The intake of thermally processed soybean reduces the feedlot period of lambs independently of roughage to concentrate ratio.

The objective of this study was to evaluate the nutrient intake and performance of feedlot lambs using 2 roughage to concentrate ratios and 2 types of soybean, whole (WS) or thermally processed (PS). Twenty male noncastrated market lambs weighting 23.26 ± 2.

Feasibility of the sentinel node biopsy in anal cancer.

Aim: Anal cancer is a rare neoplasm. According to a European Organization for Research and Treatment of Cancer multivariate analysis, synchronous inguinal lymph node metastasis occurs in 10-25% of patients and constitutes an independent prognostic factor for local failure and overall mortality.

Methods: Inguinal lymph node status was assessed using the sentinel node technique in 35 patients with anal cancer.

[The technique of sentinel lymph nodes in patients with anus neoplasm].

Anal cancer is a rare neoplasm, representing 1-2% of all large bowel cancers. Surgical excision by abdominoperineal resection has been the standard treatment. In the 1920s and 1930s inguinal node dissection was included in the surgical management of these patients.

[Verrucous carcinoma of the anus or Buschke-Lowenstein tumor of the anus: staging and treatment. Report of 3 cases].

Introduction: Giant condyloma acuminatum or Buschke Lowenstein tumor of the anorectal and perianal regions is an uncommon entity that commonly affects genitalia. These are slow-growing, expansive, cauliflower-like, destructive lesions that could propagate to vulvar and vaginal region, rectum and bladder. The hallmark of the disease is the high rate of recurrence (66%) and malignant transformation (56%).
