RESUMO

Intracerebral hemorrhage (ICH), which comprises 15 percent to 30 percent of all strokes, has an estimated incidence of 37,000 cases per year. One third of patients are actively bleeding when they present to the emergency department, and hematoma growth during the first hours after ICH onset is thought to be a prime determinant of clinical deterioration. Inflammation, as opposed to ischemia, also negatively affects patient condition. Recombinant activated factor VII is emerging as a potential first-line therapy, especially in warfarin-associated hemorrhage. Corticosteroid therapy is not supported by contemporary studies or by current management guidelines. Aggressive blood pressure reduction is under investigation. Surgical intervention has shown no statistically significant benefit over medical management for patients with ICH in general, although subgroup analysis in a large randomized trial suggested potential benefits from surgery for patients with lobar ICH. Not long ago, ICH was considered virtually untreatable. Diligent efforts in both bench and clinical research are generating hope for patients who experience this catastrophic event.

RESUMO

Recent evidence has suggested a role for vitamin D in breast cancer prevention and survival. Studies have reported an inverse relation between vitamin D intake and the risk of breast cancer, improvements in survival after a diagnosis of breast cancer in women with higher levels of vitamin D, and vitamin D insufficiency in up to 75% of women with breast cancer. Preclinical data have indicated that vitamin D affects up to 200 genes that influence cellular proliferation, apoptosis, angiogenesis, terminal differentiation of normal and cancer cells, and macrophage function. Vitamin D receptors have been found in up to 80% of breast cancers, and vitamin D receptor polymorphisms have been associated with differences in survival. Although ongoing studies have investigated a possible link between adequate levels of vitamin D and improved cancer prognosis, breast cancer survivors may derive additional, non-cancer-related benefits from adequate vitamin D levels, including improvements in bone mineral density, quality of life, and mood. Maintaining adequate vitamin D stores is recommended for breast cancer survivors throughout their lifetime.

RESUMO

Pet birds can harbor diseases that can be transmitted to their owners. This review describes the presentation, evaluation, and basic treatment of infectious syndromes caused by these bacterial, viral, protozoal, fungal, and parasitic zoonoses.

RESUMO

Aortic stenosis is the most important cardiac valve disease in developed countries, affecting 3 percent of persons older than 65 years. Although the survival rate in asymptomatic patients with aortic stenosis is comparable to that in age- and sex-matched control patients, the average overall survival rate in symptomatic persons without aortic valve replacement is two to three years. During the asymptomatic latent period, left ventricular hypertrophy and atrial augmentation of preload compensate for the increase in afterload caused by aortic stenosis. As the disease worsens, these compensatory mechanisms become inadequate, leading to symptoms of heart failure, angina, or syncope. Aortic valve replacement should be recommended in most patients with any of these symptoms accompanied by evidence of significant aortic stenosis on echocardiography. Watchful waiting is recommended for most asymptomatic patients, including those with hemodynamically significant aortic stenosis. Patients should be educated about symptoms and the importance of promptly reporting them to their physicians. Serial Doppler echocardiography is recommended annually for severe aortic stenosis, every one or two years for moderate disease, and every three to five years for mild disease. Cardiology referral is recommended for all patients with symptomatic aortic stenosis, those with severe aortic stenosis without apparent symptoms, and those with left ventricular dysfunction. Many patients with asymptomatic aortic stenosis have concurrent cardiac conditions, such as hypertension, atrial fibrillation, and coronary artery disease, which should also be carefully managed.

RESUMO

Breast cancer must be considered in the evaluation of breast masses in men, although various benign causes are more common, including gynecomastia and conditions of the skin and subcutaneous tissue. A patient's history may identify key features suspicious for malignancy or reassuring for benign disease. Physical examination has been documented to be as effective as mammography in distinguishing benign from malignant lesions, and both have been reported as highly accurate for the identification of malignancy. Mammography is therefore best used when the physical examination findings are indeterminate. Ultrasonography may be used as an adjunct to mammography; no evidence supports the use of magnetic resonance imaging in male breast patients. If clinical or mammographic features are suspicious or indeterminate for malignancy, tissue diagnosis is warranted and may be achieved surgically or via core-needle biopsy or fine-needle aspiration cytology. Given the lack of uniformity in the clinical recommendations for the evaluation of breast masses in men, a practical approach is proposed.
