Climate-Smart Livestock Systems: An Assessment of Carbon Stocks and GHG Emissions in Nicaragua.

Livestock systems in the tropics can contribute to mitigate climate change by reducing greenhouse gas (GHG) emissions and increasing carbon accumulation. We quantified C stocks and GHG emissions of 30 dual-purpose cattle farms in Nicaragua using farm inventories and lifecycle analysis. Trees in silvo-pastoral systems were the main C stock above-ground (16-24 Mg ha-1), compared with adjacent secondary forests (43 Mg C ha-1).

Placenta percreta masquerading as an acute abdomen.

Background: The incidence of placenta percreta has been on the rise during the past decades, coincident with the increase in cesarean deliveries. The diagnosis of this potentially life-threatening complication is difficult, especially when it masquerades as other severe complications of pregnancy.

Case: A woman with one previous cesarean delivery presented at 28 weeks of gestation with right upper quadrant pain.

Risk factors associated with the rupture of tubal ectopic pregnancy.

Objective: To identify risk factors that may lead to the rupture of ectopic pregnancies.

Study Design: A retrospective chart review was performed on patients with ectopic pregnancies at the University of Miami/Jackson Memorial Hospital between 1/1/1995 and 3/1/2002. 738 patients were identified with ectopic pregnancies.

Risk factors for conversion to laparotomy during laparoscopic management of an ectopic pregnancy.

Objective: To identify risk factors for conversion to laparotomy during laparoscopic management of ectopic pregnancy.

Methods: A retrospective chart review of patients who underwent laparoscopy for treatment of ectopic pregnancy, during a 32-month period (6/1999-2/2002), at the University of Miami Jackson Memorial Hospital. We identified 229 patients; 201 had a successful laparoscopy (non-converted group) and 28 who were converted to laparotomy (converted group).
