Left atrial myxoma. Clinical presentation suggesting acute myocarditis
Authors: W. H. Neches
Journal: JAMA (1974)

THE early diagnosis of left atrial myxomas is important since these tumors can be removed surgically, with excellent results.<sup>1-3</sup>However, the signs and symptoms of a left atrial myxoma are variable and in most cases, the correct diagnosis is not suspected until after systemic embolization of tumor fragments has occurred.<sup>1,3,4</sup>In many patients, the presence of mitral regurgitation has led to an erroneous diagnosis of rheumatic or viral myocarditis. This report describes the clinical findings that led to the correct diagnosis of left atrial myxoma in a child who was initially thought to have acute myocarditis. <h3>Report of a Case</h3> A 10-year-old boy was in excellent health until one week before admission when he developed signs and symptoms of an upper respiratory tract infection. Exertional dyspnea and orthopnea appeared and became increasingly severe. His physician first heard an apical systolic murmur two days before admission. There was no

“Vibes”
Authors: Lewis Thomas
Journal: New England Journal of Medicine (1972)

WE leave traces of ourselves wherever we go, on whatever we touch. One of the odd discoveries made by small boys is that when two pebbles are struck sharply against each other they emit, briefly, a curious smoky odor. The phenomenon fades when the stones are immaculately cleaned, vanishes when they are heated to furnace temperature, and reappears when they are simply touched by the hand again before being struck.An intelligent dog with a good nose can track a man across open ground by his smell, and distinguish that man's tracks from those of others. More than this, the . . .

Ribavirin treatment of experimental respiratory syncytial viral infection. A controlled double-blind study in young adults
Authors: C. B. Hall
Journal: JAMA (1983)

The effect of ribavirin aerosol on experimental respiratory syncytial virus (RSV) infection was evaluated in a double-blind controlled study of 16 young adult volunteers. Two days after intranasal inoculation with RSV, half of the subjects were treated with a small-particle aerosol of ribavirin and half with placebo for a total of 12 hours each day for three days. Seven of eight placebo-treated and six of eight ribavirin-treated subjects became infected. Viral shedding was diminished in the ribavirin-treated group. The proportion of infected volunteers still shedding virus on days 6 through 9 was significantly less than in the placebo-treated group. Ribavirin appeared to have no effect on minor upper respiratory tract signs, but systemic complaints and fever occurred significantly less often in the ribavirin-treated group. Ribavirin aerosol therapy was well tolerated and produced no significant changes in pulmonary function test results or signs of toxicity. This suggests that such therapy might be further evaluated in infants with RSV lower respiratory tract disease. (<i>JAMA</i>1983;249:2666-2670)

Functional Evaluation of the Medtronic Stentless Porcine Xenograft Mitral Valve in Sheep
Authors: Paul Dagum, G. Randall Green, Tomasz A. Timek, George T. Daughters, Linda E. Foppiano, Terrance L. Tye, Ann F. Bolger, Neil B. Ingels, D. Craig Miller
Journal: Circulation (1999)

Background —Recently, renewed interest in allograft and stentless “freehand” bileaflet xenograft mitral valve replacement has arisen. The variability of human papillary tip anatomy and scarcity of donors limit allograft availability, making xenograft mitral valves an attractive alternative; however, these valves require new surgical implantation techniques, and assessment of their hemodynamics and functional geometry is lacking. Methods —Seven sheep underwent implantation of a new stentless, glutaraldehyde-preserved porcine mitral valve (Physiological Mitral Valve [PMV], Medtronic) and were studied acutely under open-chest conditions. A new method of retrograde cardioplegia was developed. Hemodynamic valve function was assessed by epicardial Doppler echocardiography. 3D motion of miniature radiopaque markers sutured to the valve leaflets, annulus, and papillary tips was measured. Six other sheep with implanted markers served as controls. Results —Both papillary muscle tips avulsed in the first animal, leaving 6 other animals. Mitral regurgitation was not observed in any xenograft valve. The peak and mean transvalvular gradients were 4.6±1.8 mm Hg and 2.6±1.5 mm Hg, respectively. The average mitral valve area was 5.7±1.6 cm 2 . Valve closure in the xenograft group occurred later (30±11 ms, P &lt;0.015) and at higher left-ventricular pressure (61±9 mm Hg, P &lt;0.001) than in the control group; furthermore, leaflet coaptation was displaced more apically (5.6±2.2 mm, P &lt;0.001) and septally (5.8±1.5 mm, P &lt;0.001), and the anterolateral papillary tip underwent greater septal-lateral displacement (2.7±1.5 mm, P &lt;0.001). Annular contraction during the cardiac cycle was similar in the 2 groups (xenograft 9.2±4.5% versus control 10.6±4.5% [mean±SD; 2-factor ANOVA model]). Conclusions —Successful freehand stentless porcine mitral valve implantation is feasible in sheep and was associated with excellent early postoperative hemodynamics. Physiological mitral valve annular contraction and functional leaflet closure mechanics were preserved. Long-term valve durability, calcification, and hemodynamic performance remain to be determined in models.
Nonfatal Occupational Injuries and Illnesses Among Workers Treated in Hospital Emergency Departments—United States, 2003
Journal: JAMA (2006)

CDC Editorial Note: In 2005, daily monitoring of detailed data from poison control centers in Florida enabled prompt attention to health hazards related to hurricanes.Use of on-line, realtime FPICN data enabled timely detection of increases in injury and illness events before, during, and after hurricanes, enhancing FDOH capacity for delivering important public health and safety measures.These capabilities potentially reduced morbidity and mortality in Florida from these events.This local monitoring activity is similar to the national Toxic Exposure Surveillance System (TESS), which is used by AAPCC and CDC to detect potential public health threats from reports received by 61 poison control centers in the United States.7][8] However, in Florida, although the data used for TESS surveillance is maintained by FPICN, the subset of data transferred to TESS contains no personal identifiers, case notes, or data specific to the state's own monitoring system.To aid in detecting health hazards immediately before and after hurricanes, FDOH continues to use various statewide surveillance tools (e.g., hospitalbased data, emergency medical services reports, and shelter surveillance).Hospital-based surveillance relies on chief complaints, disease and injury codes, and discharge data. 9,10However, in the aftermath of hurricanes, hospitals can experience structural damage, electric power loss, limitations in available personnel, or other factors that make routine functioning and surveillance difficult.In 2004, FPICN received telephone calls during four hurricanes from residents in their homes who were told by 911
General zoology
Authors: J. Walter Beck
Journal: JAMA (1963)

As the title suggests, this is a survey of the animal kingdom. The scope of the book, within the page limitations, makes the authors deal to some degree in generalities. They have attempted quite successfully to summarize both the factual and theoretical knowledge constituting up-to-date zoological sciences. Chapters such as "Cell Metabolism" and "Chemical and Mathematical Aspects of Genetics" presuppose a knowledge of chemistry and mathematics not likely to be deeply entrenched in the minds of most beginning students of zoology and possibly questionable as part of the intellectual armamentarium of even more advanced ones. The book, however, serves as a teaching text from which the instructor can extract those topics which he wishes to emphasize. Ample reading material is available for the interested student who wishes to extend himself beyond classroom requirements. The text is well illustrated with photographs and line drawings.

Nobel Prize to Stanley Prusiner for prion discovery
Authors: J. Stephenson
Journal: JAMA (1997)

IN<i>CAT'S CRADLE</i>, novelist Kurt Vonnegut conjured a bizarre ice crystal called ice-nine that brings about disaster by converting the earth's oceans into ice. Last month, the 1997 Nobel Prize for Medicine or Physiology honored Stanley B. Prusiner, MD, of the University of California, San Francisco (UCSF), for controversial research showing that a novel class of infectious "rogue proteins" called prions similarly appears to wreak a type of transformational havoc on the brain of humans and other mammals. Prusiner's pioneering work, said the Nobel committee of the Karolinska Institute, Stockholm, Sweden, in its announcement of the award, uncovered "an entirely new genre of disease-causing agents" that many scientists believe are responsible for a variety of deadly neurodegenerative diseases. The list includes kuru, Creutzfeldt-Jakob disease (CJD),Gertsmann-Sträussler-Scheinker (GSS) disease, and fatal familial insomnia in humans, as well as transmissible spongiform encephalopathies such as scrapie and mad cow disease (bovine spongiform encephalopathy [BSE])
Adolescent Suicidal Ideation as Predictive of Psychopathology, Suicidal Behavior, and Compromised Functioning at Age 30
Authors: Helen Z Reinherz, Jennifer L Tanner, Sasha R Berger, William R Beardslee, Garrett M Fitzmaurice
Journal: American Journal of Psychiatry (2006)

Objective: The purpose of this study was to examine whether suicidal ideation in a community population of adolescents represents normative adolescent angst or is predictive of psychopathology, suicidal and problem behaviors, and compromised functioning 15 years after onset. Method: Participants were 346 largely Caucasian individuals who were part of a single-age cohort from a working class community and whose development had been traced prospectively from ages 5 to 30. Those with suicidal ideation at age 15 were compared to those without suicidal ideation at age 15 on measures of psychopathology, suicidal ideation and behavior, problem behaviors, and adult functioning at age 30. Gender differences were assessed across all domains. Results: At age 30, there were marked differences between adolescents with suicidal ideation and adolescents without suicidal ideation of both genders in most domains examined. Subjects with suicidal ideation were twice as likely to have an axis I disorder, nearly 12 times more likely to have attempted suicide by age 30, and 15 times more likely to have expressed suicidal thoughts in the past 4 years. Subjects with suicidal ideation had more problem behaviors and poorer overall functioning as assessed by multiple informants. Their self-perceptions of coping ability, self-esteem, and interpersonal relations were also lower. Although subjects with suicidal ideation among both genders had higher levels of psychopathology, suicidal ideation and behavior, and problem behaviors at age 30, male subjects with suicidal ideation had lower salaries and socioeconomic status and were less likely to have achieved residential independence. Conclusions: Findings underscore the importance of considering suicidal ideation in adolescence as a marker of severe distress and a predictor of compromised functioning, indicating the need for early identification and continued intervention.

A 33-year-old gravida 7, para 3, with juvenile diabetes (onset at the age of 13 years) was admitted to the hospital at 32 weeks' gestation with nausea, vomiting, diabetic ketoacidosis, a history of four cesarean sections and mild uterine contractions.The first cesarean section, at 21 years of age, had been performed for a breech presentation, and a year later the second yielded an eight-month stillborn fetus, supposedly victim of "a broken cord." Two and three years later, repeat sections had produced living infants weighing 3850 and 2400 g respectively. Sterilization was recommended but forbidden, and contraceptive measures were declined, . . .

Organ Procurement
Authors: Janet P. Price
Journal: JAMA (1989)

<h3>To the Editor.—</h3> We certainly agree with Dr Prottas<sup>1</sup>that the mechanisms for identifying potential organ donors and discussing the prospects of donation with the next of kin should be streamlined,<sup>1</sup>but disagree that the problem limiting organ donation is necessarily one of cooperation from medical professionals.<sup>2</sup>Our medical center is a regional trauma facility servicing both rural and urban populations in central and Southeastern Ohio. We have an aggressive organ donation policy and protocol that rapidly identifies potential vital organ donors (heart, lungs, kidneys, liver, and pancreas) and allows for initial family contact with a team consisting of an intensive care nurse, physician, and social worker or chaplain. All families are subsequently referred to organ procurement personnel for further counseling. Despite this, the number of potential donors is relatively small, and we have not seen the optimistic family response quoted by others<sup>1,2</sup>in consenting to
