Anorexia nervosa is an eating disorder characterized by unrealistic fear of weight gain, self-starvation, and PERIODICALS conspicuous distortion of body image. Anorexia nervosa was not officially classified as a ORGANIZATION psychiatric disorder until the third edition of DSM in Arthritis Foundation. In the 1970s and 1980s, anorexia was regarded as a disorder of upper- and middle-class women, but that generalization is also changing. More recent studies indicate that anorexia is increasingly common among women of all races and so- cial classes in the United States. Anorexia nervosa is a serious public health problem not only because of its rising incidence, but also because it has one of the highest mortality rates of any psychi- atric disorder. Moreover, the disorder may cause serious long-term health complications, including congestive heart failure, sudden death, growth retardation, dental problems, constipation, stomach rupture, swelling of the salivary glands, loss of kidney function, osteoporosis, anemia and other abnormalities of the blood. Causes & symptoms Anorexia is a disorder that results from the interac- tion of cultural and interpersonal as well as biological factors. While the precise cause of the disease is not known, it has been linked to the following: Social influences The rising incidence of anorexia is thought to reflect the present idealization of thinness as a badge of upper- class status as well as of female beauty. In addition, the increase in cases of anorexia includes “copycat” behav- ior, with some patients developing the disorder from imi- tating other girls. The increasing influence of the mass media in spreading planation covers all cases. Anorexia nervosa has been in- and reinforcing gender stereotypes has also been noted. This rejection is variously interpreted as a desire to remain a child, or as The risk of developing anorexia is higher among a desire to resemble men as closely as possible.

In the setting of unexplained fever erectile dysfunction caused by prostate surgery discount aurogra online visa, the catheter and sheath should al- ways be removed and cultured impotence heart disease buy aurogra american express. The catheter and sheath should be replaced at a differ- ent site if a pulmonary catheter is still indicated erectile dysfunction symptoms treatment purchase discount aurogra line. Pulmonary Artery Catheter Measurements Pulmonary Artery Pressure: Measured when the PA catheter is in its resting position in the pulmonary artery (balloon deflated). Measures both systolic pulmonary artery pres- sure and diastolic pulmonary artery pressure. Pulmonary Artery Occlusion Pressure: (also called the “pulmonary capillary wedge pressure,” or “wedge pressure”). Measured when the balloon at the tip of the PA catheter is slowly inflated with air (maximum 1. The balloon must be deflated after each PAOP measurement to avoid pulmonary infarction. In the absence of mitral valvular disease, PAOP correlates closely with the LAP and with the left ventricular end-diastolic pressure. This correlation exists because of the unobstructed continuity between the pulmonary artery and the left side of the heart. If the LVEDP increases, this should be reflected by an increase in PAOP, which, in turn, increases the PAD. Therefore, if a PA 20 catheter monitor shows a wedge pressure higher than the PAD pressure, a technical error must exist. Left Ventricular End-Diastolic Pressure: LVEDP is a measure of preload and is used to guide fluid resuscitation and optimize cardiac output. Too little volume (hypovolemia) results in too little tension and therefore a de- creased CO. Conversely, too much preload volume causes overstretching beyond the point of maximum tension and causes a decrease in CO. Clinically, the PAOP is used to keep pre- load in an optimum range to maximize stroke volume. The normal PAOP varies between 6 and 12 mm Hg, but may be higher for different disease states. Right Ventricular Ejection Fraction, Right Ventricular End-Diastolic Volume Index: A rapid-response thermistor and the cardiac output computer are used to calculate the REF. The EDVI is another measure of preload, and it allows a more accurate assessment of volume status regardless of pulmonary status. For example, a patient with severe ARDS may have markedly elevated peak inspiratory pressures. Although the CVP and PAOP may be falsely elevated, the EDVI is measuring a volume, not a pressure, allowing a more precise determination of volume sta- tus across a wide variety of clinical situations. Differential Diagnosis Table 20–4 shows normal pulmonary artery measurements (see also Figure 20–8), and the differential diagnosis based on these and other critical care parameters is shown in Table 20–5. As stated earlier, myocardial performance or CO depends on heart rate and stroke volume. Heart Rate: Heart rate, in addition to stroke volume, determines the cardiac output. Tachycardia >120 bpm in- creases myocardial O2 demand significantly and should be promptly treated.
