In situ provision of drinking water to grazing dairy cows improves milk production.

Aims: To determine the effect of providing water within the area grazed by dairy cows on milk yield and quality, compared to requiring cows to walk to a distant water trough, on a dairy farm in the Pampa region of Argentina during summer.

Methods: Holstein dairy cows were allocated to two herds with similar parity, days in milk and milk production. They were grazed in one paddock that was divided in two, with a fixed water trough at one end.

Comparison of three methods for gastrointestinal nematode diagnosis determination in grazing dairy cattle in relation to milk production.

Development of resistance to anthelmintic drugs has motivated the search for diagnostic methods to identify animals for targeted selective treatments. We compared three methods for the diagnosis of nematode infection in relation to milk production in a fully grazing dairy herd of 150 cows in the humid Pampa (Argentina). Animals had feces, blood and milk sampled during the first postpartum month for EPG, pepsinogen and anti-Ostertagia antibody determination, respectively.

Gastrointestinal parasites presence during the peripartum decreases total milk production in grazing dairy Holstein cows.

Parasitism in cattle is known to impair growth and development. Recent findings suggest that productivity of adult animals is also affected, but little is known about the physiological mechanisms involved. Furthermore, development of nematode resistance to drugs makes imperative the search of management practices that avoid whole herd treatment.

Effect of anthelmintics on reproductive performance and first-lactation culling rate in Holstein heifers.

Female Holstein calves were treated with ivermectin from birth to first oestrus to study the effect of parasitic burden and anthelmintic treatment on reproductive and productive performance. First oestrus, age at first service and age at calving were advanced by 30, 70 and 110 days, respectively (P<0.05), in ivermectin-treated animals compared with controls.

Joel-Cohen or Pfannenstiel incision at cesarean delivery: does it make a difference?

Objective: To evaluate whether the technique to open the abdomen might influence the operative time and the maternal and neonatal outcome.

Methods: All consecutive women who underwent a cesarean section at a gestational age greater than or equal to 32 weeks were randomly allocated to have either the Joel-Cohen or the Pfannenstiel incision. Exclusion criteria were two or more previous cesarean sections and previous longitudinal abdominal incision.

Postoperative complications after pelvic lymphadenectomy for the surgical staging of endometrial cancer.

Objective: To assess whether pelvic lymphadenectomy at surgical staging for endometrial carcinoma is an independent risk factor for the occurrence of postoperative complications.

Methods: Women with uterine cancer who underwent radical abdominal hysterectomy type I or II of Piver-Rutledge with or without pelvic lymph nodes dissection were considered. The occurrence of intraoperative and early postoperative complications (deep vein thrombosis, lymphocysts, febrile morbidity, extraoperative site infections, wound dehiscence, relaparotomy, and death) was prospectively recorded.

Microlaparoscopy: a new approach to the reassessment of ovarian cancer patients.

Background: The purpose of the work was to determine the feasibility and accuracy of microlaparoscopy as diagnostic method for the reassessment of ovarian cancer patients.

Methods: Eight patients scheduled for second-look laparoscopy who had undergone primary surgery for ovarian cancer followed by 6 cycles of chemotherapy were included in the study. Microlaparoscopy was performed using a 2.

A randomized clinical trial of two surgical techniques for cesarean section.

The Joel-Cohen incision followed by nonclosure of pelvic and parietal peritoneum has been advocated as an alternative method to the Pfannenstiel incision with peritonealization at cesarean section. A randomized trial was designed to compare intra- and postoperative morbidity between the two techniques. Women to undergo a cesarean section were randomly allocated to have either the Joel-Cohen incision with the parietal and pelvic peritoneum left open (group 1) or to have the Pfannenstiel incision with both peritoneal layers sutured (group 2).
