Cutaneous lymphangitis carcinomatosa: a unique presentation of a rare disease

A 75-year-old man with a three-year history of metastatic lung adenocarcinoma was diagnosed with cutaneous lymphangitic carcinomatosa of unique morphology. He was admitted to our hospital for right neck swelling, erythema, and failure to thrive. Skin examination demonstrated an indurated, thickened, firm, hyperpigmented plaque extending from the right neck and chest to the right ear, cheek, and eyelids. Skin biopsy demonstrated poorly differentiated adenocarcinoma, morphologically consistent with metastasis from the patient's known pulmonary adenocarcinoma and showed dermal invasion, perineural invasion, and involvement of dermal lymphatics. The diagnosis was an atypical presentation of cutaneous lymphangitis carcinomatosa from metastatic lung adenocarcinoma. This case presentation affirms that cutaneous lymphangitis carcinomatosa has a variety of atypical presentations, so physicians must maintain a high index of suspicion when evaluating cutaneous lesions in patients with known or suspected internal malignancy.

Position of the American Dietetic Association and Dietitians of Canada: women's health and nutrition

Within the past 10 years women's health has evolved to a much broader paradigm, beyond reproductive issues. From a physiological perspective, women's health now refers to the prevention, diagnosis, and management of conditions or diseases that may be unique to women, be more prevalent in women, or manifest differently in women than men. Women's health encompasses emotional, social, cultural, spiritual, and physical well-being. It is determined by the social, political, and economic context of women's lives. Nutrition is involved in the etiology or treatment of half of the 10 leading causes of death in women. The incidence of osteoporosis and extremes in body weight are approaching epidemic proportions in women. This position reviews the following health problems: cardiovascular disease, cancer, osteoporosis, weight, and diabetes mellitus. Dietetics professionals are in the perfect position to understand the issues surrounding women's health in order to deliver a message to women that will allow them to make wise decisions regarding their health. Nutrition is a critical component of risk reduction and treatment, and must be included in clinical and preventive services for women. Dietetics professionals must work to increase their knowledge about women's health issues, to promote health and education programs, to influence policy makers, to deliver the highest-quality medical nutrition therapy, and to be proactive in documenting the effectiveness of outcomes-based research.

Mineral homeostasis in obesity: effects of euglycemic hyperinsulinemia

We explored the effects of insulin on mineral homeostasis in five lean and six moderately obese nondiabetic premenopausal women. Serum and urine minerals were measured before and during the steady-state phase of a euglycemic insulin clamp. Each subject participated in two insulin clamp studies on separate days at insulin infusion rates of 10 and 40 mU/m2/min. Euglycemic hyperinsulinemia was associated with (1) a significant increase in urinary calcium excretion when expressed per minute with no change in total serum calcium; (2) a decrease in urine and serum phosphate; (3) a decrease in serum potassium with no change in urine potassium; and (4) no measurable effects on urine or serum sodium. At any given insulin level, the obese individuals excreted significantly more calcium, phosphate, and potassium per minute than lean controls. While insulin administration had no effect on serum parathyroid hormone (PTH) or vitamin D levels, baseline serum 1,25(OH)2D concentration was significantly higher and serum ultrafilterable calcium was significantly lower in obese subjects than in lean controls.
