The lesions of vulvar carcinoma are easily seen and palpated by the patient, but are not recognized as serious and often do not bring the patient into the office for many months. They are often pruritic, white, macerated lesions initially on the vulva that may extend to the vagina, urethra, and anal area. They begin superﬁcially but can become quite exten- sive in depth and breadth if left untreated. Biopsy is the deﬁnitive diagnostic procedure and, for squamous cell carcinoma, radical vulvectomy with inguinal and femoral lymph node dissection is the deﬁnitive treatment. Patients should be followed closely for at least 5 years for early detection of recurrences. The Pap smear is designed to detect cancer cells in the cervix and vagina. It was developed in the 1940s and, since then, the incidence of cervical cancer has declined more than 70%. The technology for the interpretation of Pap smears has improved greatly over the years, with computer-generated procedures now being used. The recommendations vary some, but for most women, a Pap smear is recommended by age 18 or sooner if the woman is sexually active. Pap smears should be repeated every 1–3 years depending on the age and history of the patient. Ask the patient about a history of abnormal Pap smears, cryosurgery, colposcopy, or cervi- cal/endometrial biopsy. Ask about any history of STDs, especially HSV and HPV, both of which can be a reason for an abnormal Pap smear. Ask about the use of diethylstilbestrol (DES) by the patient’s mother during pregnancy. Before the 1970s, the drug DES was widely used in pregnant women with threatened abortion. Subsequently, it was found to cause abnormalities and malignancies of the reproductive tract in the children of those mothers. Its use was banned in the United States in 1971, and in Europe, in 1978. While obtaining the Pap smear, a thorough gynecological exam should be performed and notations made of any cervical inﬂammation (cervicitis), discharge, STDs, or other repro- ductive abnormalities. It is important to continue Pap smears in postmenopausal women for cervical and endometrial cancer screening. Surprisingly, 25% of cervical cancers occur in women 65 years of age, and the peak incidence of endometrial cancer occurs in post- menopausal women between 50 and 60 years. In patients who have had hysterectomies, a smear of the vaginal cuff is still suggested as well as inspection of the vaginal mucosa and external genitalia looking for signs of malignancy. Patients rarely exhibit symptoms of an abnormal Pap smear unless it is due to infection or inﬂammation, in which case vaginal discharge is commonly present. The assessment and differential diagnosis for joint pain, or arthralgia, is determined by whether the pain is limited to only a few joints or is more widespread, involving several joints. Arthralgia is differentiated from arthritis, in that arthralgia simply indicates joint pain/discomfort, whereas arthritis indicates associated joint inﬂammation. Therefore, one can have arthralgia with or without accompanying signs of arthritis. The causes of joint pain are often categorized by the number of joints involved. Monoarthralgia involves only one joint, oligoarthritis involves a small number of joints (for instance, two to four), and polyarthralgia involves several (ﬁve or more) joints. The fol- lowing content on joint pain assessment is categorized by polyarthralgia and mono/oligoarthralgia. The differential diagnosis for polyarthralgia is broad and includes infections, rheumatic conditions, noninﬂammatory degenerative disorders, malignancies, and endocrine disor- Copyright © 2006 F.

NEVI Melanocytic nevi are extremely common and have genetic predetermination for the number buy kamagra soft 100mg with visa does erectile dysfunction get worse with age, distribution buy kamagra soft 100mg fast delivery erectile dysfunction cleveland clinic, and coloring among individuals. Nevi reﬂect “nests” of melanocytes with hyperpigmentation. The lesions are less than 1 cm in diameter and are evenly pigmented. The margins are well demarcated, and the shape is round. The patient reports that the nevus has existed for a long period without change. SEBORRHEIC KERATOSIS (PLATE 25) Seborrheic keratoses are common, benign skin changes found in older adults. The cause is unknown, although they do appear most commonly on sun-exposed areas. If the keratoses are subjected to frequent trauma, by location and exposure, patients may complain of itching, tenderness, or irritation at their site. Seborrheic keratoses start as ﬂat, light tan lesions and then evolve to become raised and have keratotic surfaces, often with increased pigmentation. The mature lesion has a “stuck- on” appearance and the keratotic cover can be scraped off. Although they can occur any- where, the most common sites include the trunk, face, and arms. MELANOMA (PLATE 18) Malignant melanomas are responsible for most skin cancer–related deaths each year. Most arise in sites without prior hyperpigmentation, but some do arise from previously pigmented sites. The risk is increased among fair-skinned persons with extensive sun expo- sure, persons with a family history of melanoma, and persons who have had previous changes in moles. Usually patients present with a history of a changing mole or other area of hyperpig- mentation. Like other skin disorders, there are variants in appearance, and there should be a high suspicion for melanoma in any chang- ing pigmented skin lesion. The lesions vary in appearance and size, with coloring ranging from tan to brown. There frequently is a history of a variety of developmental and congenital conditions. They range in size from millimeters to over 10 cm and are usually ﬂat macules or patches. Although the color varies, the most common coloring is that of coffee. Physical ﬁndings include signs of accompanying conditions. GIANT HAIRY PIGMENTED NEVUS These are congenital lesions. The ones classiﬁed as “giant” are over 20 cm in diameter in adults and adolescents. In infants and children, giant lesions cover at least 5% of the body surface area. The lesions have a high likelihood of becoming malignant. They are typically round or oval in shape and have an irregular surface, with coarse hairs in approximately 50% of cases. They are usual single lesions and the color ranges from light to dark brown. Inﬂammatory or Red Lesions CHERRY HEMANGIOMAS Cherry hemangiomas, or angiomas, arise from dilated venules. The cause is unknown, and they are not inﬂammatory lesions. The patient may describe onset after age 30, with number and size increasing over time.
This chapter will highlight controversial issues in its diagnosis and management and consider alternatives currently under evaluation generic 100 mg kamagra soft visa erectile dysfunction quick natural remedies. Scientific theories and developments in these areas generic kamagra soft 100 mg amex erectile dysfunction psychological, and the broader developments that can be anticipated in the global delivery of care will also be considered. Investing in the future – research evidence Critical appraisal of the medical research evidence is an essential part of therapeutic decision making, allocation of resources, and is important to attract the consumer’s confidence. Expert consensus opinion is valuable in formulating guidelines for practice – “knowledge, to become wisdom, requires experience” (Corrigan). The World Health Organization, the National Institute of Health in the US and the International Osteoporosis Foundation have published their deliberations in the last year, as have the Royal College of Physicians together with the Bone and Tooth Society in the UK. In the UK, a National Institute for Clinical Excellence has been established by the government to provide evidence-based recommendations. It is highly improbable, and indeed undesirable, 79 BONE AND JOINT FUTURES Table 6. Grade A meta-analysis or at least one randomised controlled trial or well designed controlled study without randomisation; Grade B at least one well-designed other trial type (cohort, case-control or quasi-experimental study); Grade C expert opinion, clinical experience of authorities. All of these organisations use a standard classification of research evidence (Table 6. In the context of osteoporosis, effects on bone mineral density and fracture risk must be considered separately. Evidence for the latter requires larger studies over an extended period, and therefore relatively few interventions have a high grade of evidence in this setting. A number of outstanding issues need to be considered, including: G Variations between populations have been recognised in areas such as genetics and bone mass – as most trials have studied Caucasians, they must be interpreted with caution before global strategies are considered. G Outcomes should include robust estimates of number needed to treat, as this reflects effectiveness (the product of efficacy and 80 MANAGEMENT OF OSTEOPOROSIS compliance), and the rate at which the adverse event occurs without intervention. G The number of people sustaining a fracture is a more appropriate end-point than the number of fractures (as one fracture increases the risk of another irrespective of intervention). G Specific groups should be identified for whom more cost effective short term treatment strategies can be designed. G Low cost, high compliance interventions (even of modest efficacy) may offer greater cost effectiveness than a high cost, low compliance strategy (even if of greater efficacy). The diagnosis of osteoporosis Osteoporosis is defined in pathological terms as “a progressive systemic disease characterised by low bone density and microarchitectural deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture”. However, this fragility and susceptibility may only result in an osteoporotic fracture (a vertebral fracture or minimal trauma fracture at another site, in the absence of alternative pathology) if there is a convergence of environmental factors, other illness and circumstances leading to falls (Figure 6. Osteoporosis is “established” once such a fracture occurs. While this is certainly unambiguous, osteoporosis should ideally be identified before a fracture has occurred. Therefore, for practical purposes, measured bone mineral density is compared to a Genetics Peak bone mass Nutrition Rate of bone loss Bone mass and quality Hormonal status Age Falls FRACTURE Environment Neurological Cardiovascular Figure 6. Using this classification, the disease therefore “occurs” at a selected point in a continuous slope of declining bone density. Measurement of bone mineral density Measurements of bone mineral density are currently most commonly obtained using dual energy x ray absorptiometry, for which there are internationally recommended indications. Current limitations of this technique include: G Limited reference ranges for males, younger patients and different ethnic groups. G Scoliosis, other deformities and degenerative changes (osteophytes, sclerosis, extraskeletal calcification) in the spine result in spurious increases in bone density when using anteroposterior spine views. G The working definition of osteoporosis is not related to any definitive pathological event; therefore, definitions of bone mineral density of significant risk may need to be site specific. G The role of bone mineral density in monitoring the efficacy of treatment is currently unclear; accurate ascertainment of response may require up to three or more years of therapy. It has recently been suggested that for diagnostic purposes, total hip bone mineral density should be regarded as the gold standard since this measurement is predictive of both cervical and trochanteric fractures, which collectively cause the greatest morbidity, mortality and cost of all osteoporotic fractures. Precision errors at this site are low and reference data are available for Caucasian men and women. For the purposes of fracture risk assessment in an individual, absolute rather than relative risk is relevant and should be related to an appropriate time interval, for example 10 years. Measurements of bone mineral density at other skeletal sites and using other technologies are useful in risk assessment, as are other risk factors such as previous fragility fracture, maternal history of hip fracture, risk factors for falling and increased levels of bone markers of resorption. This approach is likely to be increasingly used to determine interventional thresholds in the future rather than the T-score definition of osteoporosis.
