  • Inhibitors of the RAA System lasting effect than does captopril. Indications are hypertension and cardiac failure. Lowering of an elevated blood pressure is predominantly brought about by diminished production of angiotensin II. Impaired degradation of kinins that exert vasodilating actions may contribute to the effect. In heart failure, cardiac output rises again because ventricular afterload diminishes due to a fall in peripheral resistance.

  • A natural approach to implementing such systems is to use an existing query-based data collection system for sen- sor networks. Through queries, a user can ask for the data he or she is interested in without concern for the technical details of how that data will be retrieved or processed. A number of research projects, including Cougar [31], Di- rected Diffusion [12], and TinyDB [19,20] have advocated a query-based interface to sensornets, and several imple- mentations of query systems have been built and deployed.

  • Cushing’s disease is rare in children and adolescents. We report the clinical presenta- tions of three children with Cushing’s disease. All three exhibited the typical symptoms and signs of weight gain and growth retardation. Two also demonstrated personality changes, hypertension and hypokalemia, the last of these being rarely reported in patients with Cushing’s disease. Lack of diurnal changes in serum cortisol levels was the most common biochemical finding.

  • Vascular smooth muscle cell (VSMC) proliferation is an important etiologi-cal factor in vascular proliferative diseases such as primary atherosclerosis, hypertension, arterial and in-stent restenosis, and transplant vasculopathy. Our studies established that butyrate, a bacterial fermentation product of dietary fiber and a chromatin modulator, is a potent inhibitor of VSMC proliferation.

  • Anesthesia management is markedly influenced by pregnancy. Pregnancy-induced physiologic alterations may be compounded by labor, pregnancy-associated conditions (e.g., pregnancy-induced hypertension), or intercurrent disease states of the mother or fetus (e.g., heart disease, pulmonary hypertension, diabetes, or isoimmunization). The pregnancy alterations most influencing anesthesia are those of the cardiovascular, pulmonary, and gastrointestinal systems. At term, cardiac output is increased by 30%–40% above nonpregnant levels in the absence of aortocaval compression.

  • Examination of the optic fundi may provide direct information on a variety of conditions that affect the cardiovascular system. In patients with hypertension the retinal changes are classified according to the Keith–Wagner–Barker method. These changes reflect both atherosclerotic and hypertensive retinopathy. Initially, arterial narrowing is seen (grade 1), and subsequently the arteriolar diameters increase in relation to the venous diameters, manifested as arteriovenous nicking (grade 2 changes)....

  • Differential Diagnosis To establish the cause of metabolic alkalosis (Table 48-6), it is necessary to assess the status of the extracellular fluid volume (ECFV), the recumbent and upright blood pressure, the serum [K+], and the renin-aldosterone system. For example, the presence of chronic hypertension and chronic hypokalemia in an alkalotic patient suggests either mineralocorticoid excess or that the hypertensive patient is receiving diuretics.
