These shifts in mortality rates reflect primarily a decline in death rates for heart disease that has been observed in both sexes and is attributed to changes in lifestyle antibiotics journal discount 250 mg terramycin with visa, such as better control of hypertension and lower blood cholesterol levels interpol virus generic terramycin 250mg otc. Many of the important chronic conditions in women first appear in this age group viruswin32pariteb discount terramycin 250mg with mastercard, and the prevalence of some increases markedly during this time period antimicrobial vinyl cheap terramycin 250 mg with visa. There are significant racial and ethnic differences in the prevalence of many of these conditions. The prevalence of obesity (see Chapter 228) especially is disproportionately high in minority women; 52% of black and 50% of Mexican American women are overweight compared with 33% of white women. Because obesity is a major risk factor for diabetes, heart disease, stroke, gallbladder disease, and some cancers, and may be a factor in osteoarthritis, weight control in women is an important public health issue. The emergence of many of these conditions is inextricably linked to the menopause (see Chapter 256) and the marked decline in estrogen levels that occur during this age period. Decreased estrogen levels contribute to the development or progression of many of the disorders that are central to the aging process in women, such as heart disease, osteoporosis, and cancer. Whereas the menopause encompasses many of the physiologic changes that define this period, women also experience major transitions in social roles and life circumstances that profoundly affect their physical and mental health. Children leave home, many women become widowed or divorced, parenting roles change as women are called on to care for aging parents, and disabilities increase, making it difficult for some women to function within and outside the home. Not surprisingly, 3% of women will experience a major depressive episode during this period. An understanding of these life events is essential to the comprehensive care of mature women. Heart disease is the leading cause of death in older women, followed by cancer and stroke. Mortality rates for all three disorders rise steeply after age 65 and begin to approach the rates for men. Chronic pulmonary disease and pneumonia continue to cause high death rates because of the increase and severity of infections associated with an age-related decline in immune function. Injury is the sixth leading cause of death in older women; most of these deaths are related to falls. After age 65, many other chronic illnesses, such as hypertension, diabetes, the arthritides, most digestive disorders, and thyroid disease, are more common in women than in men of the same age and cause significant morbidity. Of these, the neurologic degenerative diseases, such as dementia, sleep disorders, and neurosensory and movement disorders, are particularly common in women. Unfortunately, the added years of life in women are often spent in a frail or dependent state and often result in institutionalization. In particular, urinary incontinence (see Chapter 119) and osteoporosis (see Chapter 257) put women at high risk for institutionalization. Prevalence rates of urinary incontinence are twice as high in women as in men and affect up to one half of community-dwelling women. Osteoporosis is associated with deformity and pain secondary to vertebral fractures; however, hip fracture, usually the result of a fall, is the most serious consequence of osteoporosis in older women. According to the National Osteoporosis Foundation, one half of women with a hip fracture will never walk independently, one third will never live independently, and one fifth will die within a year of the fracture. The social and psychological changes that women experience as they age add to the burden of illness. Social isolation increases as a result of death of loved ones, loss of financial stability, and increasing physical disabilities. In addition to an increasing incidence of dementia with age, mental health problems become more prevalent or serious. In an analysis by Bartman of differences in the delivery of medical care to women among physician specialties, family practitioners provided the majority of non-obstetric care to women aged 15 and older (57%); internists and gynecologists provided decreasing amounts of the remaining services (25% and 18%, respectively). Within internal medicine and gynecology, there was an age gradient in the provision of services; as women age, the proportion of care delivered by gynecologists decreased whereas that provided by internists increased. There were also specialty-specific differences in the type of service provided by each discipline. Family practitioners and internists provided services for both acute and chronic non-gynecologic disorders, whereas gynecologists provided little of this care. In contrast, over half of general medical examinations and two thirds of routine gynecologic services were provided by gynecologists. When the realities of clinical practice are examined, the issues are more complex. There is considerable overlap between the practice parameters of family practice and general internal medicine and those of obstetrics and gynecology.

Despite the ready availability of bronchoscopy infection 4 weeks after surgery cheap terramycin 250mg overnight delivery, the etiology of nosocomial pneumonias is often frustratingly difficult to establish with certainty antibiotics for urinary tract infection over the counter generic 250 mg terramycin with mastercard. Evaluation of the efficacy of treatment is confounded by the severity of underlying disease present in most of these patients; mortality rates of 20 to 30% are not uncommon among patients treated with agents that have demonstrated in vitro activity against the infecting organism antibiotic 3 days for respiratory infection order 250mg terramycin. Agents other than fluoroquinolones must be given parenterally and in adequate dosage antibiotic kennel cough terramycin 250 mg without prescription. The results of monotherapy rival those of multidrug regimens when broad-spectrum agents such as third-generation cephalosporins (ceftazidime or cefotaxime), carbepenems (imipenem or meropenem), beta-lactam/beta-lactamase inhibitor combinations (piperacillin/tazobactam or ticarcillin/clavulanate), or fluoroquinolones (ciprofloxacin or alatrofloxacin) are used. Dosages of 5 mg/kg every 24 hours for gentamicin and tobramycin; 15 mg/kg every 24 hours for amikacin. Treatment of nosocomial infection is made more difficult by previous antimicrobial therapy, and drug susceptibility studies are critically important. However, empirical therapy usually must be initiated before the results of such studies are available. Factors to consider when selecting appropriate therapy include knowledge of local resistance patterns, previous culture results, and prior treatment. Amikacin is often used in this setting because of less frequent resistance to this agent. A single daily dose of an aminoglycoside has been shown to be equally as effective as more frequent dosing and may be less nephrotoxic. Prospective studies have shown that carefully chosen empirical regimens are inadequate in up to 73% of cases when invasive sampling techniques are used to determine the etiologic organisms. Causes of inadequacy are the presence of resistant organisms singly or in polymicrobial infections; up to 40% of nosocomial pneumonias are polymicrobial. When the pathogenic organisms have been identified and the susceptibility patterns are known, modifications can be made to optimize antibiotic therapy. Ideally, antibiotics with the narrowest spectrum of activity, the least toxicity, and the best lung penetration should be chosen. In neutropenic patients and in seriously ill patients with pneumonia caused by resistant organisms such as P. Duration of therapy should be based on clinical response, but a minimum of 2 to 3 weeks is usually required. The observed level of mortality depends on the population studied and has been reported as high as 91%, but it is more commonly in the range of 20 to 50%. That adequate therapy did not reduce mortality in some studies is explained by the fact that underlying disease is the main predictor of survival for many patients. Early, broad-spectrum therapy that covers all of the organisms present in the lung is important for patients with survivable illnesses. Important complications include empyema, lung necrosis, superinfections, and multiple organ failure; metastatic seeding of infection to other sites is an uncommon complication. Criteria for the diagnosis of empyema, besides the presence of gross pus, include the presence of bacteria on Gram stain, pleural fluid pH less than 7. Each of these criteria indicates a condition that is unlikely to respond to antimicrobials alone and that usually requires drainage of the pleural space as well. Thus the term complicated effusion has gained favor over empyema to identify pleural fluid collections for which drainage needs to be considered. The occurrence of a complicated effusion generally prevents the recovery of the patient until it is recognized and effectively treated. If pleural fluid is identified on upright posteroanterior and lateral chest radiographs, thoracentesis should be performed; useful studies of the fluid obtained include measurements of pH and glucose, white blood cell count, Gram stain, and cultures for aerobic and anaerobic organisms. If the fluid qualifies as a complicated effusion, prompt placement of a thoracostomy tube should be considered. Alternative approaches (principally, repeated thoracentesis) are less successful, owing to loculation of the pleural space. Surgical drainage of the pleural space, using localized resection of an overlying rib with creation of a larger drainage tract, is reserved for patients who do not respond to tube drainage and are not candidates for a larger operation. Decortication of the pleura may be necessary if the clinical signs of uncontrolled infection are not ameliorated by simple drainage plus antimicrobial therapy. In such patients, radiographic 1615 evidence of effusion persists, along with continued fever and leukocytosis.

To modify this fertile intracellular culture environment, the host must destroy the heavily parasitized macrophage, liberating its contents into the extracellular milieu. This is the situation that occurs in the tuberculoid form of the disease and is lacking in the lepromatous state. The components and schedules vary depending on the presence of dapsone-sensitive strains and the part of the world in which the patient resides. To evaluate the dapsone sensitivity, the mouse foot pad assay must be used; this procedure is available only in specialized facilities. Multibacillary disease- a bacillary index of 1+ or more at any one of six skin sites. It should be noted, however, that many leprologists use rifampin at 450 to 600 mg/day for 2 to 3 years. Rifampin is the most rapidly effective bactericidal agent and kills the majority of M. Therapy with clofazimine, a phenazine derivative, has certain unpleasant side effects based on its lipophilicity. The compound is a red-purple dye taken up and concentrated by macrophages of the skin, causing increased skin pigmentation. Clofazimine is also deposited in the small intestine, where at high concentrations it causes segmental thickening associated with crampy pain and diarrhea. If clofazimine is unacceptable to patients, the physician should consider substitution with 100 mg/day of minocycline or 400 mg/day of ofloxacin. With severe episodes, high doses of corticosteroids (prednisone, 60 to 80 mg/day) are necessary and should be tapered off as soon as feasible. It is given initially at 200 mg twice a day and then tapered to levels of 50 to 100 mg/day. Thalidomide is a potent teratogen and should be assiduously avoided if pregnancy is possible. The chronicity and potential nerve damage of this cell-mediated reaction require high-dose corticosteroids and careful evaluation of peripheral nerve condition. Thalidomide is not used in this condition, but clofazimine along with corticosteroids allows the more rapid withdrawal of prednisone. A number of surgical procedures are available at specialized leprosy hospitals to help correct footdrop, hand deformities, madarosis, and lagophthalmos. Plastic surgical procedures can replace nasal septa and help close large plantar ulcerations. The presence of a cold abscess of a peripheral nerve with sudden increase in pain and functional loss requires immediate decompression by surgical drainage. Trials with more prolonged administration have demonstrated that a systemic response can be achieved. In lepromatous disease, prolonged courses of multiple drugs arrest the progression of the illness when compliance is good. It is the ability of the public health infrastructure to monitor compliance that is central to effective therapy. Education of the general public plays an important role in sensitizing individuals to the nature of leprosy and the ability to cure the illness with medication. Once a case has been identified in a household, careful physical examination of all contacts with the biopsy of suspicious lesions should be carried out. In this adolescent category, the prophylactic use of dapsone should be considered. New knowledge has accumulated rapidly about old diseases; for instance, it is now clear that cervical carcinoma is a complication of certain human papillomavirus (genital wart virus) infections. Some relatively less severe infections, such as chlamydial ones, are known to be alarmingly prevalent in young persons.
