Cultural Diversity In order to provide culturally competent care to exercisers quality 100mg penegra, it is necessary to be exposed to and understand the cultural beliefs order penegra mastercard, values purchase penegra line, and practices of the desired population. This includes but is not limited to housing, neighborhood characteristics, religion, access to resources, crime, race, ethnicity, age, ability level, and social class. For example, the higher levels of physical inactivity among African Americans compared to other racial/ethnic groups may be caused not only by environmental constraints but also by cultural beliefs (70). Including strategies that address these barriers may be essential in interventions focusing on this population. Perhaps the most important characteristic of exercise interventions that target different racial/ethnic groups is being culturally sensitive and tailored. Culturally sensitive interventions should include surface structure and deep structure (76). Surface structure involves matching intervention materials and messages to observable, “superficial” characteristics of the target population. The people, places, language, music, food, locations, and clothing that are familiar to and preferred by the population should be used. For example, an intervention targeting African Americans should include pictures of African Americans in program materials. Including both dimensions within interventions can increase the receptivity and acceptance of the messages (surface structure) and saliency (deep structure) (76). Older Adults There are several challenges when working with promoting the adoption and adherence of exercise among older adults (see Chapter 7) (2,23). Although typically viewed as beneficial, social support is not necessarily positive, especially in older adults (20). Family and friends may exert negative influences by telling them to “take it easy” and “let me do it. Quite possibly, the largest barrier to exercise participation in older adults is the fear that exercise will cause injury, pain, and discomfort or exacerbate existing conditions (66). Youth When working with children (see Chapter 7), it is important to recognize they are likely engaging in an exercise program because their parents wish them to, implying an extrinsic motivation, and typically require tangible forms of social support (e. However, to help children maintain exercise behavior over their lifetime, they need help shifting toward a sense of autonomy (98) and to feel a sense of self-efficacy and behavioral control. Individuals with obesity may have had negative mastery experiences with exercise in the past and will need to enhance their self-efficacy so they believe that they can successfully exercise (7,21). A concern when working with individuals with chronic diseases and health conditions is their ability to do the exercise both from a task self-efficacy perspective as well as in the face of the barriers specifically related to their condition (66). Special consideration should be given to ensure activities are chosen to prevent, treat, or control the disease or health condition. Furthermore, being aware of the unique barriers and fears of individuals with chronic diseases and health conditions can help assure the physical activities chosen are appropriate.

E—Endocrine reminds one of the increased incidence of basilar artery thrombosis in diabetes order 50 mg penegra with mastercard. Supranuclear causes (including cortical): These recall a pineal tumor buy generic penegra 100mg on-line, the conjugate palsy of cerebral thrombosis or hemorrhage purchase genuine penegra line, the conjugate gaze in focal cortical epilepsy, and the dilated pupil in early herniation through the tentorium. Approach to the Diagnosis 283 This is similar to that for all neurologic disorders and depends on the association of other signs. Isolated palsies of the third (oculomotor) or sixth (abducens) nerve without pupillary changes suggest diabetic neuropathy, so a glucose tolerance test would be done. An isolated palsy of the third nerve with pupillary changes (mydriasis) suggests an aneurysm and angiography is indicated. A cavernous sinus thrombosis is possible if the patient is febrile and has more than one cranial nerve palsy along with loss of the corneal reflex, chemosis, ecchymosis, and distended retinal veins. Based on a review of the methods outlined above, what are your possible diagnoses at this point? There is no history of headache, alcohol or drug use, or any other neurologic symptomatology. Neurologic examination revealed a left external rectus palsy and bilateral partial ptosis. The fact that the patient remains conscious distinguishes drop attacks from syncope or the vasovagal attack and epilepsy. Nevertheless, these attacks result from a temporary decrease in blood supply to centers in the brainstem responsible for muscle tone. Consequently, we can develop a differential diagnosis by following the arterial tree from the heart to the 286 brainstem. Aorta: Aortic stenosis and insufficiency may be the cause of recurring drop attacks. Arteries: Focusing on the arteries in general we can recall orthostatic hypotension either related to drugs, anemia, or idiopathic type. Vertebral–basilar arteries: Atherosclerotic narrowing of these arteries leads to transient cerebral ischemia and drop attacks. This leaves a few conditions that may simulate drop attacks in elderly persons such as weak quadriceps muscles, poor vision, postural instability from posterior column degeneration, and tripping over unseen objects. The clinical picture and neurologic or cardiology consult will help determine if Holter monitoring or four- vessel cerebral angiography should be done. Beginning with the pituitary one thinks of hypopituitarism and Lawrence–Moon–Biedl syndrome. The brain suggests microcephaly and all the other causes 287 of mental retardation (such as Down syndrome) that are associated with stunted growth. For the regulation and promotion of this metabolic process, adequate vitamins and hormones are essential. With these processes in mind, one can recall the diseases that interfere with each. Intake: Starvation and malnutrition cause dwarfism and various vitamin deficiency states, rickets being the most significant. Absorption: Malabsorption syndromes may create dwarfism by preventing food and vitamins from getting into the body. Transport: Congenital anomalies of the heart prevent distribution of oxygen and glucose to the cells. Cell uptake: Impaired cell uptake of glucose in diabetes may cause a short stature; the bulging of the cells with glycogen in glycogen storage disease may do the same. Regulation: This heading helps recall the hormonal deficiency states: cretinism (deficiency of thyroxine), Turner syndrome (deficiencies of estrogen and progesterone), and hypopituitarism (deficiency of growth hormone). The adrenal carcinomas may cause precocious puberty and premature closure of the epiphysis. The above method fails to include most of the genetic causes of dwarfism, so perhaps this group can be remembered by its exclusion. Approach to the Diagnosis The workup of dwarfism should probably be done by an endocrinologist. All of these have associated findings that should help to differentiate them, but hypopituitarism may be very subtle. Down syndrome, Turner syndrome, and certain other genetic causes can be determined by a chromosomal analysis. Dysarthria: This may be due to a lesion at the end organ (muscles of the mouth and tongue), the myoneural junction, the peripheral branches of the 5th (trigeminal) and 12th (hypoglossal) cranial nerves, the brainstem, or the cerebrum. End organ: Hypertrophy of the tongue from myxedema, carcinoma of the tongue, and painful lesions of the mouth and tongue may cause speech difficulty. Inability to swallow may leave saliva and food in the mouth and interfere with speech. Myoneural junction: Myasthenia gravis, a treatable form of dysarthria, should always be ruled out. Peripheral nerve: Hypoglossal nerve damage from trauma and severing of the motor portion of the trigeminal nerve in trauma and surgery are the principal lesions here. Brainstem: Poliomyelitis, Guillain–Barré syndrome, disseminated encephalomyelitis, brainstem gliomas, and basilar artery occlusions are the most important lesions to recall in this category. Cerebrum: Any disorder that may cause hemiplegia from cerebral involvement may cause dysarthria and pseudobulbar palsy. Cerebral thrombi, emboli, or hemorrhages are perhaps the most significant of these. Diffuse cerebral diseases such as alcoholism, Huntington chorea, and general paresis may cause dysarthria, but they are more likely to cause other speech disorders. Dysphasia: In this condition, words cannot be pronounced properly (motor dysphasia), there is difficulty naming objects (nominal aphasia), or the words cannot be placed properly in a sentence (syntactic aphasia). In determining the etiology, it is not important to know the exact location of the lesion in the cerebrum because any disease of the cerebrum may cause aphasia or dysphasia. Cerebral hemorrhages, thrombi, emboli, and tumors or other space-occupying lesions are the most important ones to remember. Extrapyramidal speech: This is the monotone, rapid, dysarthric speech of paralysis agitans, but it may be found in cerebral palsy, Wilson disease, or Huntington chorea. Approach to the Diagnosis Dysarthria without other symptoms or signs requires that myasthenia gravis be ruled out with a Tensilon test and psychometrics be done to rule out hysteria. At the cervix, stenosis, cervical polyps, and other neoplasms may obstruct the egress of blood and induce dysmenorrhea. In the uterus, polyps, fibroids, adenomyosis, and deformities such as anteflexion, retroflexion, anteversion, or retroversion may be the cause. The ovaries may be involved by the same processes as the tubes, but they should suggest the most common cause of dysmenorrhea: hormonal.

Then the hub of the needle should be depressed toward the patient’s skin and advanced toward the left shoulder at an angle of 15° to 30° to the patient effective 50mg penegra. Local anesthetic is injected as needed penegra 100 mg fast delivery, and gentle suction should be applied to the syringe when advancing discount penegra 50 mg mastercard. In the average adult, the distance from skin to pericardium is approximately 6 to 8 cm (1). Fluoroscopy was previously the most common method used as to guide pericardiocentesis, but this approach has largely been supplanted by echocardiography. For this approach, either a polytef-sheathed needle with an attached saline-filled syringe or a Tuohy-17, blunt-tip introducer needle can be used. The needle is directed to the left shoulder and toward the anterior diaphragmatic border of the right ventricle, at about 30° angle to the skin. The purpose is to avoid the coronary, pericardial, and internal mammary arteries with this direction and angulation. Upon penetration into the pericardial space, needle position may be confirmed with injection of radiopaque contrast media. The left lateral with a slight left anterior angiographic view, or an anteroposterior view, provides the best visualization of the puncturing needle in relation to the diaphragm and the pericardium. As the needle is advanced, the operator should perform moderate suction, and once fluid is obtained, it is advised to inject very small amounts of contrast until the pericardial silhouette is demarcated on the fluoroscope, a phenomenon known as the “halo sign. The soft J-tip wire may be confirmed to be in the pericardium by identifying how it crosses from the right to the left chambers, because a wire in the right ventricle would not cross to the left side unless a ventricular septal defect is present. A subxiphoid approach is used as described above, aiming the needle toward the left shoulder. However, because of the significantly higher rates of complications and because of the increased availability of bedside ultrasound, blind taps should be avoided unless absolutely necessary. If the cause of the pericardial effusion is not clear, the fluid should be sent for analysis. Therefore, all fluid from idiopathic effusions should be sent for bacterial, mycobacterial, and viral cultures; cytologic examination; acid-fast bacillus smear; cell count; protein; glucose; and lactate dehydrogenase. Blood samples should be sent for chemistry, complete blood count, blood cultures (if bacterial infection is likely), thyroid-stimulating hormone, erythrocyte sedimentation rate/C- reactive protein, antinuclear antibody, and rheumatoid factor (if connective tissue disease is suspected). Consideration should also be given to conducting a tuberculin purified protein derivative skin test. Blind pericardiocentesis has been associated with morbidity rates as high as 20% and mortality rates as high as 6%. Therefore, complications are relatively rare in experienced centers, although one must be mindful of the following: A. If the parasternal approach is used, remaining close to the sternum decreases the risk of pneumothorax. This is usually asymptomatic and self-sealing, particularly if the left ventricle is entered. Right ventricular perforations have a somewhat higher likelihood of bleeding when perforated, but right atrial lacerations carry the highest risk. If laceration is suspected, the needle or catheter should be withdrawn and the patient should be observed overnight in an intensive care setting. The left internal thoracic/mammary artery runs down the chest wall about 1 to 2 cm lateral to the sternum, with the vein running slightly more medial. Left chest wall and subxiphoid approaches must take this anatomy into consideration. The posterior descending artery may be lacerated on subxiphoid approaches if the needle is aimed too medially. On a chest wall approach, the intercostal arteries and nerves are avoided by passing the catheter just superior to the rib. Sterile technique during the procedure and meticulous catheter care afterward if a drain is left in place minimize this risk. As the Mayo series suggests, the risk of catheter-related infection is very low, even among cancer patients. This is exceptionally rare when procedures are performed by experienced operators with echocardiographic guidance. A postprocedure chest film should be obtained in all patients to exclude pneumothorax. Patients without significant comorbidities who have uncomplicated diagnostic taps do not require inpatient care following the procedure. Care of an indwelling pericardial catheter is similar to that for any central line. After the catheter is sutured in place, the site is treated with an antibacterial ointment and then dressed sterilely. Continuous drainage can also be used, but the risk of catheter obstruction is higher. If the fluid becomes purulent or the patient becomes septic, the catheter must be removed. The catheter is typically left in place for 1 to 2 days, but extended drainage has been associated with lower rates of effusion recurrence. Before pulling the drain, an echocardiogram should be obtained to ensure resolution of the effusion. Sometimes, when the drainage volume is minimal, it may be useful to clamp the catheter for few hours and observe the patient for clinical signs of tamponade. Alternatively, an echocardiogram can also be performed in order to assess for reaccumulation once the drain is clamped.

Choosing Among Antibiotics Within a Class: Beta-lactams and Beta-lactamase Inhibitors, Macrolides, Aminoglycosides, and Fluoroquinolones 1 Gram-negative organisms as one goes from the frst-generation cephalosporins (cepha- lexin and cefadroxil), to the second generation (cefaclor, cefprozil, and cefuroxime) that demonstrates activity against Haemophilus infuenzae (including beta-lactamase– producing strains), to the third-generation agents (cefdinir, cefxime, cefpodoxime, and cefibuten) that have enhanced coverage of many enteric Gram-negative bacilli (Escherichia coli, Klebsiella spp). The palatability of generic versions of these products may not have the same better-tasting characteristics as the original products. A second-generation cephalosporin (cefuroxime) and the cephamycins (cefoxitin and cefotetan) provide increased activity against many Gram-negative organisms, particularly Haemophilus and E coli. Cefoxitin has, in addition, activity against approximately 80% of strains of Bacteroides fragilis and can be considered for use in place of the more active agents, like metronidazole or carbapenems, when that organism is implicated in nonseri- ous disease. Tird-generation cephalosporins (cefotaxime, cefriaxone, and cefazidime) all have enhanced potency against many enteric Gram-negative bacilli. As with all cephalosporins, at readily achievable serum concentrations, they are less active against enterococci and Listeria; only cefazidime has signifcant activity against Pseudomonas.
