A RECENT monogram issued by the Metropolitan Life Insurance Company, New York, on "The MIortality from the Principal Cardio-vascular Renal Diseases During the Twenty-Years Period from 1911 till 1930," shows how great a factor these diseases are in influencing the death-rate. For the age period 1-24 years approximately eight per cent. of all (leaths are due to cardio-vascular renal diseases, wit...

BACKGROUND Older adults face important risky decisions about their health, their financial future, and their social environment. We examine age differences in risk-taking behaviors in multiple risk domains across the adult life span. METHODS A cross-sectional study was conducted in which 528 participants from 18 to 93 years of age completed the Domain-Specific Risk-Taking (DOSPERT) scale, a s...

Studies comparing young and older adults suggest a deficit in processing context information as a key mechanism underlying cognitive aging. However, the genetic architecture of context processing has not been examined. Consistent with previous results, we found evidence of functionally dissociable components of context processing accuracy in 1127 late middle-aged twins ages 51-60. One component...

Multifrequency tympanometry data were measured multiple times between the ages of four weeks and two years from 33 infants/toddlers. Tympanograms were also measured from 33 adult participants. Tympanograms recorded with five probe-tone frequencies (226, 400, 630, 800, and 1000 Hz) were classified using the Vanhuyse et al model classification system (Vanhuyse et al, 1975). Admittance at +200 daP...

The current research had 2 aims: (1) to determine the cross-sectional age differences in self-concept clarity during adulthood and (2) to examine the importance of social role experiences for age differences in self-concept clarity. These aims were addressed in 2 large samples of adults ranging in age from 18 to 94 years. In both studies, self-concept clarity had a curvilinear relation to age s...

OBJECTIVE The International Study of Asthma and Allergies in Childhood (ISAAC) is a standardized method that allows international and regional comparisons of asthma and allergic diseases prevalence. The objective of this study was to evaluate the prevalence of rhinitis and related symptoms among 6-7 year-old children (SC) and 13-14 year-old adolescents (AD) from 20 Brazilian cities applying the...

Although cross-sectional (between-person) comparisons consistently reveal age-related cognitive declines beginning in early adulthood, significant declines in longitudinal (within-person) comparisons are often not apparent until age 60 or later. The latter results have led to inferences that cognitive change does not begin until late middle age. However, because mean change reflects a mixture o...

liposarcoma is a mesenchymal malignant tumor and is the second-most common soft tissue sarcoma in adults. primary peritoneal liposarcoma is very rare. we report a case of abdominal liposarcoma originating from peritoneum in 57-year old woman, presenting with hugeness of abdomen.   the symptoms had been begun from one month ago without any pain, discomfort or gastrointestinal symptoms. in physic...

background: the term caustic generally refers to alkaline and the term corrosive generally refers to acidic agents' injury however, in medical literature caustic is frequently a term applied to both substances. ingested alkali typically damage the esophagus more than stomach or duodenum, whereas acids usually cause more severe gastric injury. since esophagus has a slightly alkaline ph, its...
