In addition, because cardiovascular disease is the major killer of patients with diabetes, aggressive risk factor reduction should be attempted, including smok- ing cessat ion and reduct ion of hypercholesterolemia. She has no other medical problems and says t hat at her last opht halmologic appoint ment she was told that t he dia- betes had started to affect her eyes. Physical examination is normal except for hard exudates and dot hemor- rhages on funduscopic examination, and diminished sensation up to the mid-shin bilaterally. H ave the patient return in 6 weeks and check a repeat urine analysis at that time. Change the glyburide to glipizide and have the patient return for follow- up in 6 weeks. Changing from one sulfonylurea to anot her is of no benefit because all are equally efficacious. T here is no indica- tion for referral to a cardiologist based on the information provided in the vign et t e. Given his recent episode of pharyngitis, the most likely cause would be post infect ious, probably due t o st rept ococcal infect ion. In the outpatient setting, a dipstick urinalysis is readily available but will det ect only pat ient s wit h overt neph ropat hy (prot einuria >300 mg/d). Thus, a random urinary albumin/creatinine ratio of 30/300 is the best test to screen for early diabetic nephropathy. Finally, although most patients with nephrotic syndrome require a renal biopsy for diagnosis, a pat ient wit h worsening renal funct ion who has had long-st anding diabet es is assumed to have renal disease secondary t o diabet ic nephropat hy, and t he majority of these patients do not undergo a renal biopsy. Examination at that time reveals that he is afebrile, his heart rate is regular at 56 bpm, and his blood pres- sure is 109/65 mm Hg. His fundus reveals dot hemorrhages and hard exudates, his neck veins are flat, his chest is clear, and his heart rhythm is normal with an S gallop and no murmur or friction rub. H is funduscopic examination shows dot hemorrhages and hard exudat es, evidence of diabet ic ret inopat hy. In t his sett ing, t he baseline elevated creat inine level on admission likely represent s diabet ic nephropathy as well. Next step: Urinalysis and urine chemistries to determine whether the process is prerenal or renal, or less likely post renal. Be familiar with the management of hyperkalemia and indications for acute dialysis. Acu t e o b st r u ct ion, cor t ical necrosis, and vascular catastrophes such as aortic dissection should be considered in t he different ial diagnosis. Physiologically, it is the lowest amount of urine a person on a normal diet can make if he or she is severely dehydrated and does not ret ain uremic waste product s. Pat ient s wit h oliguric renal failure have higher mortality rates and less renal recover y t h an do pat ient s wh o are nonoliguric. Sometimes, the clinical presentation is straightforward, such as volume depletion from gast r oin t est in al flu id loss or h em or r h age; at ot h er t im es, the pr esen t at ion of patients with prerenal failure can be more confusing. For example, a patient with severe nephrot ic syndrome may appear to be volume overloaded because of the massive peripheral edema present, while the effective arterial blood volume may be ver y lo w a s a co n seq u en ce o f the s ever e h yp o alb u m in em ia. Similarly, a patient with severe congestive heart failure may h ave prerenal failure because of a low cardiac eject ion fract ion, yet be flu id over load ed wit h p er iph er al an d p u lm on ar y ed ema. Table 30– 1 provides an abbreviated list ing of the et iologies of prerenal failure. Postrenal failure, also refer red t o as obst r uct ive n eph ropat h y, implies blockage of urinary flow. T h e sit e of obst r uct ion can be anywh ere alon g the ur in ar y syst em, including t he int ratubular region (cryst als), uret ers (st ones, ext rinsic compression by tumor), bladder, or urethra. By far, the most common causes of obstructive nephropathy are ureteral obstruction due to malignancy, or prostatic obstruc- tion due to benign or malignant hypertrophy. The patient’s symptoms depend on wh et h er or not bot h kidneys are involved, the degree of obst ruct ion, and the t ime cou r se of the blockage. Intrinsic renal failure is caused by disorders that injure the renal glomeruli or tubules directly. D oes t he pat ient have signs or sympt oms of a syst emic disease, such as heart failure or cirrhosis, that could cause prerenal failure? D oes the pat ient have sympt oms of a disease, such as lupus, t hat could cause a glomerulonephrit is? Is the patient receiving an antibiotic and now has allergic interstitial nephritis? In addit ion t o t he hist ory and physical examinat ion, urinalysis and measurement of urinary electrolytes are h elpful in making t he diagnosis. In dividu- als wit h postrenal failure typically are unable to concentrate the urine, so the ur in e osmolality is equal to the serum osmolality (isosthenuria) and the specific grav- ity is 1. The microscopic findings vary depending on the cause of the obstruc- tion: hemat uria (cryst als or st ones), leukocyt es (prost at ic hypert rophy), or normal (extrinsic ureteral compression from a tumor). Tubulointerstitial nephritis classically p r o - duces urine that is isosthenuric (the tubules are unable to concentrate the urine), wit h mild proteinuria, an d on microscopy, r eveals leukocytes, white cell casts, and urinary eosinophils. F E represents the amount of Na sodium filtered by the kidneys that is not reabsorbed. N or mally, the excr et ed sodium repr esent s Na the dietary intake of sodium, maintaining sodium homeostasis. Fur t h er more, becau se the pat ient h as eit h er t r ue Na vo lu m e d ep let io n o r “effect ive” vo lu m e d ep let io n, ser u m ald o st er o n e will st im u lat e the kidneys to retain sodium, and the urinary sodium will be low (< 20 mEq/ L). D iuret ic medicat ions, wh ich int erfere wit h sodium reabsorpt ion, are often used in congestive heart failure or nephrot ic syndrome. Early in the course of Na postobstructive renal failure caused by ureteral obstruction, the afferent arteriole typically undergoes intense vasoconstriction, with consequent, low urinary sodium levels ( Table 30– 3). Becau se of the r isk of fat al cardiac ar rh yt h mias, sever e hyperkalemia is considered an emergency, best treated acutely medically and not with dialysis. Although it will not lower the serum potassium level, the calcium will oppose the membrane effects of the high potassium concentration on the heart, allowing time for other methods to lower the potassium level. One of the most effective methods for treating hyper- kalemia is administration of intravenous insulin (usually 10 units), along with 50 to 100 mL of 50% glucose solution to prevent hypoglycemia. Pot assium also can be driven int racellularly with a bet a-agonist, such as albuterol, by nebulizer. All t hree therapies have only a transient effect on serum potassium levels, because the total body potassium balance is unchanged, and the potassium eventually leaks back out of the cells.

Park The nasal tip is one of the most difficult areas to address in rhi- Mastering structural support and dynamics begins with noplasty. Many of the rhinoplasty master surgeons are quoted understanding the theories that describe their behavior. Just as regarding the difficulty of addressing the nasal tip and have long-term difficulties arose from the early reductive rhinoplasty written about methods to address it. Many younger surgeons techniques and led to preservationist philosophies, the prevail- still approach the tip with caution and tend to use formulaic ing models describing structural dynamics of the nasal tip have methods they learned in fellowship, only advancing many years evolved. The early theories dealt more with tip position, and later to the tailored approach. What is it about the nasal tip that with time the theories progressed to explain the role of struc- makes it so difficult? To answer that question definitively would mean the author Anderson is credited with creating the first comprehensive had found the explanation and surgical method that resulted in description of tip dynamics, coining the “tripod” concept in a perfect tip every time. As facial plastic surgeons we have an excellent the theoretical basis for the current models we have today. This understanding of the anatomy of the nasal tip, yet achieving chapter will describe the history of these theories and explain our desired alterations remains difficult to predict because of their fundamental concepts, helping the reader to understand the change in structural dynamics caused by surgery. An anal- the nuances of the current theories about structural support ogy will help to clarify. Facial plastic surgeons understand the detail of their project’s anatomy in as much detail as an architect does with In 1969, one of the first otolaryngologists turned facial plastic his or her building. However, unlike the raw materials used in surgeons, Jack Anderson, coined the term “the nasal tripod” in a construction, facial plastic surgeons work with raw materials presentation to the Ninth International Congress in Otorhino- that are alive, are heterogeneous in load bearing, heal with laryngology. One becomes This model enabled a simple yet elegant structural view of acraftsman. It was easy to see the eﬀects of ate the rhinoplasty surgeon from the architect; they take a various surgical maneuvers on the projection or rotation of the lifetime to master and, in the words of Zola, “become a tip based on their change in length of the legs of the tripod. In other words, the legs of the theoretical tripod did not extending the support of the lateral crus to the pyriform opening; exist in free space, but consisted of cartilages of known strength (3) the ligamentous sling spanning between the paired domes of and were attached to or built upon adjacent parts of the nose. Janeke and Wright attachments combined to create the structural support compo- approached the nasal tip from a static structural point of view nents of the tip. The unification of these two perspectives was first noted by At about the same time, Janeke and Wright published the results 4 McCollough and Mangat more than a decade later. These structural support mechanisms worked well with an extension of the shorter mesial leg of the tripod concept. Anderson’s tripod theory as the surgeon could focus tripod- Anderson’s original tripod theory was limited in its description altering maneuvers on the areas of major support of the tripod of the mesial leg as the combined medial crura of the lower to have the greatest eﬀect in tip rotation and position. Larrabee added to the description of the McCollough and Mangat’s four structural points were similar to mesial leg the fatty tissue at the base of the columella on which Janeke and Wright’s but were more recognizable from our the feet of the medial aura rested. For the record, their four importance (the membranous attachment of the feet of the structural components were: (1) the telescoping relationship of medial crura to the caudal septum). Placement of a columellar strut of the nasal septum; and (4) the “ligamentous attachment” of was often seen as the gold standard in maintaining the base of the anterior septal angle to the domes of the lower lateral carti- the nose (the mesial limb) but other variations such as the lages. Note the removal of the sesamoid cartilages and the addi- tongue-in-groove technique and septal extension grafts were tion of the strength/integrity of the lateral crura (not the entire also described. It is noteworthy to mention that the majority of nasal tip structural support and dynamics literature has been anecdotal yet accepted as scientific truth. However, our field As surgeons became more experienced in rhinoplasty, further has suﬀered from a deficit of both true experimental and quan- refinements in the models of structural support and dynamics titative biomechanical research. One of those with the biggest and enduring In a move that is hopefully a preview of the wave and type of impacts on the field was Tardy and Brown’s more detailed enu- future research, Dobratz and colleagues quantified the strength meration of the tip’s structural support mechanisms. Although the and-groove technique and septal extension graft were equal in three major support mechanisms remained similar to those strength, and both provided more resistance to tip displace- described by McCullough and Mangat, Tardy and Brown ment than the preoperative nose. A free-floating columellar emphasized their importance and moved the “ligamentous strut was weaker than the preoperative nose, but stronger than attachment” mechanism to a more minor category in addition to adding other minor mechanisms involved in tip support. These major and minor tip support mechanisms are still the most referenced and have been the foundation of the tip support literature for the last 20 years. However, as the authors point out, there is an obvious selection bias in that patients judged to have less tip support intra- operatively had the more robust columellar reconstruction performed. However, these “framework” theories do not address, in architectural terms, the “fit and finish” work of rhinoplasty; they do not describe changes in nasal tip form and shape. As such, the surgeon will often categorize the surgery into initial framework steps to modify projection, rotation, and long-term support, followed by finer, more detailed steps to address the tip shape. A degloved nose (from an external rhino-plasty Before moving on to a discussion of modern variations of tip approach) was the weakest of all. This last statistic confirms the structural support and dynamic theory, which do incorporate theories mentioned earlier in that strength is lost when even tip shape, we will enumerate some of the common tip-altering one major (medial crural attachments to caudal septum) and a maneuvers and their eﬀects on important structural support few minor (interdomal ligament, attachments of lower lateral and dynamics. A notable correlation in rhinoplasty patients failed to find any postoperative change in tip position with time regard- 32. This makes sense according to the tripod model and has been shown empirically, further strengthening the tripod concept. From the structural stand- point, a cephalic trim reduces the inherent strength of the lower lateral cartilages and disrupts the scroll region, two of the three major support mechanisms for the tip. For this reason, we have seen the emergence of more conservative recommen- dations for the amount of trim to be performed, as well as aug- menting the lateral crura with lateral crural struts from either septal cartilage or autografts from an inward turning of the cephalic trim cartilage. Depending on how the lower lateral cartilage is reconstructed, the surgeon also has control of tip rotation by lengthening or shortening the lateral limbs. Although some ardent proponents of routine dome division remain, the disrup- tion of a major support mechanism, the ability to have major control over the tripod, and subsequent propensity for erratic healing, unpredictable contracture, and loss of projection have caused most to shy away from its routine use. This stands to reason from both the dynamic tri- pod concept (strengthen the mesial limb) and the major struc- tural support concept (strengthen medial crural attachment to columellar septum). However, mediate crura to ensure symmetric height of the tip-defining they can create a perceived change in tip dynamics depending points and/or narrow the tip-defining points depending on the on their nature. This suture does A shield graft can increase rotation and projection depending not have much perceived eﬀect on tip projection or rotation. Batten grafts will augment the scroll region as well Adamson and Funk coined the “M-arch” term in an attempt to as the lateral-most aspect of the lateral crura, adding strength integrate nasal tip shape with structural support and dynamic theory. Alar strut grafts will augment the lateral crura and increase support, and builds on the idea of medial and lateral limbs of the lower but because of their parallel orientation, they increase the lateral cartilages that create the foundation of the nasal tip. It adds length of the lateral limb of the tripod, causing a decrease in a more detailed description of the nasal tip area traversed by the rotation and increase in projection. It notes there are two paired “domal arches” that are formed by the intermediate crus and the anterior aspect of the lateral crus.
Accordingly discount keflex 250 mg line virus transmission, if we know to which category a particular adrenergic agonist belongs keflex 500mg without prescription antibiotics for uti rash, we will know three of its prominent features order discount keflex antibiotic resistance lab report. Catecholamines The catecholamines are so named because they contain a catechol group and an amine group keflex 750 mg without a prescription good antibiotics for sinus infection. A catechol group is simply a benzene ring that has hydroxyl groups on two adjacent carbons. Because of their chemistry, all catecholamines have three properties in common: (1) they cannot be used orally, (2) they have a brief duration of action, and (3) they cannot cross the blood-brain barrier. Both enzymes are very active and quickly destroy catecholamines administered by any route. Because these enzymes are located in the liver and intestinal wall, catecholamines that are administered orally become inactivated before they can reach the systemic circulation. Be aware that catecholamine-containing solutions, which are colorless when first prepared, turn pink or brown over time. The only exception is dobutamine, which can be used up to 24 hours after the solution was made, even if discoloration appears. Noncatecholamines The noncatecholamines have ethylamine in their structure (see Fig. As a result, the half- lives of noncatecholamines are much longer than those of catecholamines. Third, noncatecholamines are considerably less polar than catecholamines and hence are more able to cross the blood-brain barrier. Receptor Specificity To understand the actions of individual adrenergic agonists, we need to know their receptor specificity. Variability in receptor specificity among the adrenergic agonists can be illustrated with three drugs: albuterol, isoproterenol, and epinephrine. In the upper part of the table, receptor specificity is presented in tabular form. By learning this content, you will be well on your way to understanding the pharmacology of the sympathomimetic drugs. Arrows indicate the range of receptors that the drugs can activate (at usual therapeutic doses). The ability of a drug to selectively activate certain receptors to the exclusion of others depends on the dosage: at low doses, selectivity is maximal; as dosage increases, selectivity declines. For example, when albuterol is administered in low to moderate doses, the drug is highly selective for beta -adrenergic2 receptors. So-called selective agents will activate additional adrenergic receptors if the dosage is abnormally high. Therapeutic Applications and Adverse Effects of Adrenergic Receptor Activation In this section we discuss the responses—both therapeutic and adverse—that can be elicited with sympathomimetic drugs. Because many adrenergic agonists activate more than one type of receptor (see Table 13. Consequently, rather than attempting to structure this presentation around representative drugs, we discuss the actions of the adrenergic agonists one receptor at a time. Our discussion begins with alpha1 receptors, and then moves to alpha receptors, beta receptors, beta receptors,2 1 2 and finally dopamine receptors. For each receptor type, we discuss both the therapeutic and adverse responses that can result from receptor activation. To understand the effects of any specific adrenergic agonist, all you need are two types of information: (1) the identity of the receptors at which the drug acts and (2) the effects produced by activating those receptors. This is the same approach to understanding neuropharmacologic agents that we discussed in Chapter 10. We are about to discuss the clinical consequences of adrenergic receptor activation, and Table 11. Clinical Consequences of Alpha Activation 1 In this section we discuss the therapeutic and adverse effects that can result from activation of alpha -adrenergic receptors. Therapeutic Applications of Alpha Activation1 Activation of alpha receptors elicits two responses that can be of therapeutic1 use: (1) vasoconstriction (in blood vessels of the skin, viscera, and mucous membranes); and (2) mydriasis. Of the two, vasoconstriction is the one for which alpha agonists are used most often. Alpha agonists are given to stop bleeding primarily in1 the skin and mucous membranes. Nasal Decongestion Nasal congestion results from dilation and engorgement of blood vessels in the nasal mucosa. Specific alpha -activating 1 agents employed as nasal decongestants include phenylephrine (administered topically) and pseudoephedrine (administered orally). Adjunct to Local Anesthesia Alpha agonists are frequently combined with local anesthetics to delay systemic1 absorption. The mechanism is alpha -mediated vasoconstriction, which reduces1 blood flow to the site of anesthetic administration. Because keeping the drug at the local site of action prolongs anesthesia, allows a reduction in anesthetic dosage, and reduces the systemic effects that a local anesthetic might produce. Elevation of Blood Pressure Because of their ability to cause vasoconstriction, alpha agonists can elevate1 blood pressure in hypotensive patients. Please note, however, that alpha agonists1 are not the primary therapy for hypotension. Rather, they are reserved for situations in which fluid replacement and other measures either are contraindicated or have failed to restore blood pressure to a satisfactory level. Mydriasis Activation of alpha receptors on the radial muscle of the iris causes mydriasis1 (dilation of the pupil), which can facilitate eye examinations and ocular surgery. Note that producing mydriasis is the only clinical use of alpha activation that is1 not based on vasoconstriction. Adverse Effects of Alpha Activation1 All of the adverse effects caused by alpha activation result directly or indirectly1 from vasoconstriction. Hypertension Alpha 1 agonists can produce hypertension by causing widespread vasoconstriction. The cause is lack of blood flow to the affected area secondary to intense local vasoconstriction. If extravasation occurs, the area should be infiltrated with an alpha -blocking agent (e. The mechanism is this:1 alpha -mediated vasoconstriction elevates blood pressure, which triggers the1 baroreceptor reflex, causing heart rate to decline. In patients with marginal cardiac reserve, the decrease in cardiac output may compromise tissue perfusion. However, their ability to activate alpha2 2 receptors in the periphery has little clinical significance because there are no therapeutic applications related to activation of peripheral alpha receptors.
Benzoyl peroxide must be washed off prior to application of tretinoin or the retinoid will be rendered ineffective 500 mg keflex amex virus doctor sa600cb. It is available in over-the-counter preparations with variable uniformity generic keflex 500mg with amex antibiotics for lower uti, stability buy keflex 250 mg low price antibiotics for uti levaquin, and efficacy purchase keflex on line amex antibiotics give acne. Although these over- the-counter preparations eliminate bacteria at the skin surface, they do not have a carrier vehicle that allows deep follicular penetration. A benzoyl peroxide wash is beneficial when lesions are widely distributed or when adherence to a treatment plan is problematic. Washes are applied in the shower and then rinsed off after approximately 30 seconds. Benzoyl peroxide can bleach fabric, so careful and thorough rinsing and drying is recommended. Topical tretinoin, a vitamin A derivative, inhibits the formation of microcomedo- nes and increases cell turnover. Patients should use a mild soap (Dove, Cetaphil) and allow the skin to dry 20 to 30 minutes prior to applying nightly tretinoin. Mild redness and peeling can occur, and patients should avoid sun expo- sure and use sunscreens. This agent is teratogenic and causes irritation, so it should be used with caution. Some believe that azelaic acid applied twice daily for 4 to 6 months may provide acne relief, especially for those sensitive to other agents, and theoretically can reduce scarring. Topical, rather than systemic, antibiotics are preferred because of their fewer side effects. Topical antibiotics (erythromycin, clindamycin) often are applied to affected areas twice daily or in combination with benzoyl peroxide or tretinoin. Long-term topical or oral antibiotic monotherapy is not recommended due to the potential development of bacterial resistance. Combination benzoyl peroxide and topical antibiotic preparations can be particularly beneficial, and do not typically promote resistance. Oral antibiotics (doxycycline, erythromycin, tetracycline) are used when moderate to severe inflammatory and pustular acne does not respond to topical treatment. Tetracycline is the most frequently used oral antibiotic because it is inexpensive and has few side effects. To minimize the potential for antibiotic resistance, oral antibiotics ideally should be discontinued after a few months. Anti- biotics, irrespective of the formulation, should be discontinued once inflammatory lesions are under good control. Isotretinoin (Accutane) is the treatment of choice for severe, resistant nodulocys- tic acne. It is highly teratogenic and has many side effects, including mood dysregulation, cheilitis, conjunctivitis, hyperlipidemia, blood dyscrasias, elevated liver enzymes, and photosensitivity. Lipid levels, liver enzymes, and complete blood counts should be monitored monthly dur- ing the course. Females should have a negative pregnancy test immediately before isotretinoin is initiated and should maintain effective contraception before, during, and after therapy. Oral contraceptives (Ortho Tri-Cyclen) are approved for treatment of acne, and intralesional steroid therapy is sometimes used in unresponsive cases. He has inflammatory pap- ules and pustules in the beard and moustache area and has mild cervical lymphadenopathy. The skin around the pimples and elsewhere is unremarkable, as is the rest of his examination. Depression is a rare side effect of isotretinoin, but it can be severe and suicides have been reported. Tinea barbae is caused by various dermatophytes and closely resembles tinea capitis. Approximately 20% of normal neonates develop at least a few comedones within the first month of life. The cause of neonatal acne is unknown, but has been attributed to placental transfer of maternal androgens, hyperactive adrenal glands, and a hypersensitive neonatal end-organ response to andro- genic hormones. Tretinoin can lead to photosensitivity; patients should avoid sun exposure or use sunscreen. Tetracycline should be taken on an empty stomach; milk products bind tetracycline. The effects of culture, skin color, and other nonclinical issues on acne treatment. At the last parent–teacher conference, his teacher noted that he is eas- ily distracted and routinely fails to complete both homework assignments and classroom papers. His mother states that at home he also has difficulty in com- pleting tasks and he fidgets constantly. Target outcomes can then be identified and a behavioral therapy, classroom modification, and possibly medication treatment plan designed. In addition, the following conditions must be met: £ Several inattentive or hyperactive-impulsive symptoms were present before age 12. Alternatively, information can be surmised through narratives or descriptive interviews. Management includes the implementation of a long-term treatment program in collaboration with caregivers and teachers. Behavioral modification can be used alone or in conjunction with pharmacologic therapy. Positive reinforcement (providing rewards or privileges) and negative con- sequences (time-out or withdrawal of privileges) emphasize appropriate behavior. Small class size, structured work, stimulating schoolwork, and appropriate seat- ing arrangements can help decrease disruptive classroom behaviors. Commonly used stimulant medications include methylphenidate and dextroamphetamine. Atomoxetine (Strat- tera) is a nonstimulant, selective norepinephrine reuptake inhibitor approved for use in adults and children. Tricyclic antidepressants, clonidine and bupropion, often prescribed under the direction of a psychiatrist or neurologist, are also used. Approximately 50% of children func- tion well in adulthood; others demonstrate continued inattention and impulsivity symptoms. Thus, in all patients who are considered for the diagnosis of attention deficit disorder other diagnostic possibilities must be considered. At home he is always restless, never seems to pay attention, and is always losing things.
