Pleural uid does not displace the heart, as occurs in those with unilateral tho- racic masses or abscesses. Therefore heart sounds are audible bilaterally and may appear to radiate caudodor- sally by sound conduction through the pleural uid. Pleural uid must be differentiated from anterior ventral pulmonary consolidation. Bronchial tones usually are heard in consolidated regions of lungs, whereas absence of sounds is more typical of pleural uid.

Medical expenditures for urinary incontinence Urinary incontinence is regarded as an important among female Medicare benefciaries (65 years of age risk factor for nursing home admission. Research and older) nearly doubled between 1992 and 1998 has indicated that a signifcant proportion of those from $128. This change in venue probably borne by patients themselves as part of routine care refects the general shift of surgical procedures to (22) (Table 25). Expenditures for female Medicare benefciaries age 65 and over for treatment of urinary incontinence (in millions of $), (% of total) Year 1992 1995 1998 Total 128. Expenditures for female urinary incontinence and share of costs, by type of service (in millions of $) Year 1994 1996 1998 2000 Totala 324. Average drug spending for incontinence-related conditions (both male and female) is estimated at $82 million to $102 million annually for the period 1996 to 1998. Expenditures for female Medicare beneficiaries age 65 and over for the treatment of urinary incontinence (in millions of $). Visits during The indirect costs for urinary incontinence are which patients return for follow-up after treatment estimated by measurements of work lost (Tables 28 are also often coded as visits for incontinence, even and 29). While providers can 23% of women missed work, while only 8% of men be urged to code more diligently, administrative did so. Average annual work absence for women databases alone will never yield the degree of clinical totaled 28. Although women of urinary incontinence and its impact on women and men had similar numbers of outpatient visits for in the United States. Classifcation and Coding Despite these limitations, administrative databases Existing databases allow researchers to describe do allow investigators to paint broad-brush pictures trends in incontinence surgery and hospitalization of the overall picture of urinary incontinence in more accurately than trends in outpatient visits or American women. Costs of urinary incontinence in 1995 (in Given the large number of women affected by millions of $) urinary incontinence, future studies focusing on both Cost Factor prevention and treatment are vital.

Patients describe this type of incontinence residents report diffculty controlling their urine as diffculty in holding their urine until they are and require assistance using the toilet, either from able to reach a toilet. In males, physical examination may reveal mechanisms as demonstrated during urodynamic clues to the etiology of the underlying condition, but testing. In general, defnitions are divided into those only rarely is the actual sign of incontinence seen.
