Benign cephalic histiocytosis in a 2-year-old boy with an inconspicuous clinical presentation at onset.

We report on a 2-year-old boy whose initially inconspicuous skin lesions later on evolved into a typical clinical presentation of benign cephalic histiocytosis (BCH). The diagnosis of BCH can often be made on clinical grounds without the need for an extensive diagnostic work-up. Given the benign and self-limited course of the disease treatment is not required and the clinical management can be limited to a watchful waiting approach.

Enteric methane emissions by lactating and dry cows in the high Andes of Peru.

The objective of the study was to determine enteric methane emissions using the sulfur hexafluoride (SF) technique and comparing with The Intergovernmental Panel on Climate Change (IPCC) methodology in lactating cows (LC) and dry cows (DC) in the Peruvian highlands. Enteric methane (CH) emissions were measured on 5 LC and 6 DC Brown Swiss in a grazing system without concentrate. Forages samples were collected and analyzed for dry matter, crude protein, and neutral detergent fiber.

Balloon angioplasty and stent implantation performed through systemic-to-pulmonary artery shunts in infants and neonates.

Branch pulmonary artery stenosis (BPAS) in the setting of systemic-pulmonary artery shunts (SPS) may result in significant sequelae. Limited information exists regarding the safety and efficacy of pulmonary artery balloon angioplasty and stent implantation via SPS in neonates and infants. This study aimed to examine the feasibility, safety, and efficacy of balloon angioplasty/stent implantation for BPAS performed via SPS in neonates and infants.

Stent implantation is effective treatment of vascular stenosis in young infants with congenital heart disease: acute implantation and long-term follow-up results.

Background: Stents implantation in infants has been shown to be feasible, however, there are no published reports examining long-term outcomes. Concerns exist regarding creation of fixed obstructions secondary to the stent if expansion to larger diameters over time is not possible.

Methods: A retrospective analysis of the earliest consecutive series of infants who underwent stent placement at our institution between October 1995 and December 1999.
