Osteoporosis affects a significant number of men, yet the condition often goes undetected and untreated. The evaluation of osteoporosis in men requires special consideration as some of the laboratory testing to assess underlying causes in men differs from those in women. The rate of bone loss accelerates in women at menopause and continues to progress at a slower pace in older postmenopausal women (see Figure 3) and in older men. Lecture 5 (2008), with permission of the International Society for Clinical Densitometry. In these groups, the diagnosis of osteoporosis should not be made on the basis of densitometric criteria alone. The decision to perform bone density assessment should be based on an individual’s fracture risk profile and skeletal health assessment. Utilizing any procedure to measure bone density is not indicated unless the results will influence the patient’s treatment decision. Preventive Services Task Force recommends testing of all women age 65 and older and younger women whose fracture risk is equal to or greater than that of a 65- 20 year-old white woman who has no additional risk factors. Most vertebral fractures are asymptomatic when they first occur and often are undiagnosed for many years. The finding of a previously unrecognized vertebral fracture may change the diagnostic classification, alter future 22 fracture risk calculations and affect treatment decisions. The presence of a single vertebral fracture increases the risk of subsequent 23 fractures 5-fold and the risk of hip and other fractures 2- to 3- fold. Indications for Vertebral Imaging Because vertebral fractures are so prevalent in older individuals and most produce no acute symptoms, vertebral imaging tests are recommended for the individuals defined in Table 7. Once a first vertebral imaging test is done, it only needs to be repeated if prospective height loss is documented or new back pain or postural 5,24 change occurs. A follow up vertebral imaging test is also recommended in patients who are being considered for a medication holiday, since stopping medication would not be recommended in patients who have recent vertebral fractures. Economic modeling was performed to identify the 10-year hip fracture risk above which it is cost-effective, from the societal perspective, to treat with 12 pharmacologic agents. Patients who have been off osteoporosis medications for one to two years or more might be considered 27 untreated. The therapeutic thresholds proposed in this Guide are for clinical guidance only and are not rules. Conversely, these recommendations should not mandate treatment, particularly in patients with low bone mass above the osteoporosis range. Additional Bone Densitometry Technologies The following bone mass measurement technologies included in Table 8 are capable of predicting both site- specific and overall fracture risk. When performed according to accepted standards, these densitometric 19 techniques are accurate and highly reproducible. The following technologies are often used for community-based screening programs because of the portability of the equipment. It may measure the microarchitectural structure of bone tissue and may improve the ability to predict the risk of fracture. These include an adequate intake of calcium and vitamin D, lifelong participation in regular weight-bearing and muscle-strengthening exercise, cessation of tobacco use, identification and treatment of alcoholism, and treatment of risk factors for falling. Adequate Intake of Calcium and Vitamin D Advise all individuals to obtain an adequate intake of dietary calcium. Providing adequate daily calcium and vitamin D is a safe and inexpensive way to help reduce fracture risk. Controlled clinical trials have 29 demonstrated that the combination of supplemental calcium and vitamin D can reduce the risk of fracture. A balanced diet rich in low-fat dairy products, fruits and vegetables provide calcium as well as numerous nutrients needed for good health. If adequate dietary calcium cannot be obtained, dietary supplementation is indicated up to the recommended daily intake. Lifelong adequate calcium intake is necessary for the acquisition of peak bone mass and subsequent maintenance of bone health. The skeleton contains 99 percent of the body’s calcium stores; when the exogenous supply is inadequate, bone tissue is resorbed from the skeleton to maintain serum calcium at a constant level. There is no evidence that calcium intake in excess of these amounts confers additional bone strength. Intakes in excess of 1,200 to 1,500 mg per day may increase the risk of developing kidney stones, cardiovascular 31,32,33,34 disease and stroke. Table 9 illustrates a simple method for estimating the calcium content of a patient’s diet. The average daily dietary calcium intake in adults age 50 and older is 600 to 700 mg per day.

Sometimes, intra-abdominal lymphadenopathy involving portahepatis, pre- and para-aortic and mesenteric lymph nodes; retroperitoneal lymphadenopathy may be present. Thus transbronchial lung biopsy gives a higher diagnostic yield in miliary sarcoidosis.

Hypoalbuminaemia Hypercalcaemia When caseous material, collagen or both are Hypophosphatemia present in the tubercles, these became visible on the Hyperbilirubinaemia 122 chest radiograph. The diagnostic evaluation of this patient illustrates the judicious use of imaging modalities to defne the extent of organ system involvement and procuring tissue for diagnostic confrmation. In addition to the miliary pattern, well-defned, linear, branching opacities (tree-in-bud appearance) (thick white arrows) (A and B) are also seen. This pattern is evident when centrilobular bronchioles are dilated, or, are flled with mucus, fuid or, pus and represents endobronchial spreading of infection. In some patients, predominance of Ultrasonography: Ultrasonography helps in detecting lesions on one side may be evident (Fig. Some ascites which may sometimes be loculated, focal patients may have normal chest radiographs initially hepatic and splenic lesions and cold abscesses, and the typical miliary pattern may evolve over the intra-abdominal lymphadenopathy, involvement course of disease. This is particularly evident in of other abdominal organs and pleural effusion(s).

Recent trends Drug trafficking, the critical link between supply and Despite increased attention to drug demand reduction demand, is fuelling a global criminal enterprise valued in in recent years, drug use continues to take a heavy toll. There organized criminals are forming transnational networks, continues to be an enormous unmet need for drug use sourcing drugs on one continent, trafficking them across prevention, treatment, care and support, particularly in another, and marketing them in a third.

Heroin consumption has stabilized in Europe and cocaine consumption has declined in North America – A stronger multilateral response to illicit drugs the most lucrative markets for these drugs. But these In the face of such diverse and complex challenges, we gains have been offset by several counter-trends: a large must improve the performance of our global response to increase in cocaine use in Europe and South America illicit drugs.
