Modern approaches to the treatment of breast cancer

Breast cancer is the most common cause of cancer death in women in this country. Until recently, the traditional treatment has been radical surgery with or without radiation therapy for patients with primary breast cancer, and palliative endocrine therapy followed by chemotherapy for patients with advanced disease. These treatments have met with limited effectiveness in terms of eradicating the disease. Studies in the past decade have given cause for optimism for breast cancer patients. Adjuvant systemic therapy after local treatment appears promising for certain subsets of patients with primary breast cancer. The development of estrogen receptor assays has markedly changed our approach to the disease and improved patient care. Estrogen receptor is an important prognostic factor and is useful in planning appropriate therapy for patients with primary breast cancer as well as those with advanced disease. Further research is urgently needed to improve the dismal survival of certain women with this common malignancy.     

Thrombosis and survival in essential thrombocythemia: A regional study of 1,144 patients

To identify prognostic factors affecting thrombosis‐free survival (TFS) and overall survival (OS), we report the experience of a Regional cooperative group in a real‐life cohort of 1,144 patients with essential thrombocythemia (ET) diagnosed from January 1979 to December 2010. There were 107 thrombotic events (9.4%) during follow‐up [60 (5.3%) arterial and 47 (4.1%) venous thromboses]. At univariate analysis, risk factors for a shorter TFS were: age >60 years (P < 0.0054, 95% CI 1.18–2.6), previous thrombosis (P < 0.0001, 95% CI 1.58–4.52) and the presence of at least one cardiovascular risk factor (P = 0.036, 95% CI 1.15–3.13). Patients with a previous thrombosis occurred ≥24 months before ET diagnosis had a shorter TFS compared to patients with a previous thrombosis occurred <24 months (P = 0.0029, 95% CI 1.5–6.1); furthermore, patients with previous thrombosis occurred <24 months did not show a shorter TFS compared with patients without previous thrombosis (P = 0.303, 95% CI 0.64–3.21). At multivariate analysis for TFS, only the occurrence of a previous thrombosis maintained its prognostic impact (P = 0.0004, 95% CI 1.48–3.79, RR 2.36). The 10‐year OS was 89.9% (95% CI 87.3–92.5): at multivariate analysis for OS, age >60 years (P < 0.0001), anemia (P < 0.0001), male gender (P = 0.0019), previous thromboses (P = 0.0344), and white blood cell >15 × 10⁹/l (P = 0.0370) were independent risk factors. Previous thrombotic events in ET patients are crucial for TFS but their importance seems related not to the occurrence per se but mainly to the interval between the event and the diagnosis. Am. J.

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.     

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.
