The east–west advancement flap (horizontal advancement flap) to repair a defect on the nose ala

Background The repair of an alar nasal defect is a frequent challenge for dermatologic surgeons for reasons of the high rate of non‐melanoma cancers in the area. Objective Our aim was to describe the use of an east–west cheek‐based flap (horizontal advancement flap) to repair a surgical defect on the nose ala. Methods Benefits and limits of this surgical procedure are evaluated. Result The resulting S‐shaped scar was well‐camouflaged among the natural skin lines (melolabial fold and melonasal junction). No architectural distortion of the nose resulted from the procedure. Conclusion In selected patients with small‐to‐medium‐size defects of the nasal ala, the horizontal advancement flap is a simple, reliable and aesthetic reconstruction option.     

LONG-TERM EFFECTS OF CHEMOTHERAPY ON DENTAL STATUS IN CHILDREN TREATED FOR NEPHROBLASTOMA

Dental abnormalities among children treated at a young age for Wilms tumor are reported. The authors retrospectively reviewed the dental records and panoramic radiographs of 27 children treated for nephroblastoma between 1994 and 1998. They evaluated the frequency of apparent microdontia, excessive caries, root stunting, hypodontia, and enamel hypoplasia and compared this group to a control group of 78 children. Seventy percent of the children developed dental abnormalities, comprising root stunting (44%), enamel hypoplasia (22%), microdontia (18%), and hypodontia (7%). Results of control subjects were significantly different regarding dental abnormalities, especially microdontia and taurodontia. These results indicate that chemotherapy in children may lead to troubles affecting teeth growing at the time of treatment. Information and prospective dental care are needed, and further investigations are required.     

Percutaneous fluoroscopic removal of a knotted Swan–Ganz catheter in a patient with a persistent left‐sided superior vena cava

Knotting of intravascular catheters is an uncommon but a well‐recognized occurrence. The Swan–Ganz catheter (SGC) is the one that knots most commonly. A case of a knotted SGC is described in a patient with a persistent left‐sided superior vena cava, and we propose that the presence of a left‐sided superior vena cava is a risk factor for knot formation not previously reported. We review the published work on the risk factors for knot formation and on the techniques used to remove knotted SGC. We describe a technique using a gooseneck snare and Omni Flush catheter (Angiodynamics, Queensbury, NY, USA) to loosen and untie a knotted SGC.
