Thermally Induced Formation of Polychlorinated Dibenzofurans from Aroclor 1254-Contaminated Mineral Oil
Authors: Rajinder S. Narang, Kamal Swami, Vincent Stein, Robert Smith, Patrick O'Keefe, Kenneth Aldous, David Hilker, George Eadon, Charles Vernoy, Amarjit S. Narang
Journal: Environmental Health Perspectives (1989)

Numerous laboratory simulations and real-world events have demonstrated the thermal conversion of neat or high concentration of PCBs into the much more toxic PCDFs. Since millions of mineral oil transformers currently in service contain PCB concentrations in the 50 to 5000 ppm range, the thermal behavior of dilute PCB solutions is of practical and regulatory significance. In this work, neat Aroclor 1254 and 5000 ppm Aroclor 1254 in mineral oil were subjected to pyrolysis and combustion under a range of experimental conditions to define parameters resulting in maximal PCDF yields. The dependence of PCDF yield on Aroclor 1254 concentrations was then investigated in the 5000 to 50 ppm range. Combustion experiments demonstrated that PCDF yields expressed as micrograms PCDF/gram PCB were independent of concentration range, confirming that the process is kinetically first order in PCB. Much lower yields of PCDF were observed in the open tube pyrolysis experiments, as compared to combustion experiments and to earlier and concurrent sealed tube experiments. Slightly improved yields were observed in the pyrolysis experiments at lower concentrations, suggesting the existence of a PCB or PCDF destruction process of higher than first order kinetics. In all cases, yields expressed as micrograms PCDF/gram mixture were sharply and monotonically lower as concentrations decreased between neat or 5000 ppm Aroclor 1254 and 50 ppm Aroclor 1254.

A case of postoperative pulmonary embolism with its successful surgical removal illustrates that in selected cases surgical treatment of pul- monary embolism is indicated.It is suggested in a scheme of management of the patient with major pulmonary embolism that if there is no response to conservative measures within 30 min- utes and there are no contraindications, such as incurable disease, operation should be under- taken without further delay.SAGALL
Edith Potter, MD, PhD: pioneering infant pathology
Authors: N. Y. Hoffman
Journal: JAMA (1982)

Finding Edith Potter, MD, PhD, the "mother of perinatal pathology," is not easy. You board a tenpassenger propeller-driven plane at the Tampa—St Petersburg airport, fly to Fort Myers, then drive past motels, fast-food chains, factory outlets, and supermarkets. Finally, a sharp left and a quick right, and "Palm Pointe Gardens" reads a bronze plaque on two stone posts guarding a hidden road. Suddenly you're in a tropical paradise. Bronze and terra-cotta figures, Narcissus-like, watch their reflections in a freshwater spring, or gaze out at a meandering estuary of the Gulf of Mexico. Following the narrow dirt road, heavy with vegetation, you park by a glass-roofed orchid house. Can this unlikely place be Potter's abode? Yes, there she is, waving from the steps of her stucco house built for "retirement" in 1967. Wearing a blue denim sundress almost the color of her slate-blue eyes (analytic behind blue-rimmed glasses), she shows you
Health care workers infected with the human immunodeficiency virus. The next steps
Authors: B. Lo
Journal: JAMA (1992)

The tragedy of five patients who contracted human immunodeficiency virus (HIV) infection from a seropositive dentist has alarmed the public. The Centers for Disease Control (CDC) recently revised its recommendations for preventing the transmission of HIV infection to patients during invasive procedures. The CDC abandoned a previous plan to list exposure-prone invasive procedures that HIV-infected health care workers should not perform. The CDC said "expert review panels" should decide on a case-by-case basis whether seropositive health care workers may perform invasive procedures. As of February 1992, the revised recommendations were under review by the US Department of Health and Human Services. Many issues remain to be clarified, such as how these panels will operate and whether decisions will be consistent in similar cases. Disregarding the CDC guidelines or infection-control precautions may further erode public trust and lead to draconian restrictions on HIV-infected health care workers. Physicians and dentists should respond more effectively to public fears about HIV transmission. The challenge is to protect patients while respecting the privacy and livelihood of health care workers. (<i>JAMA</i>. 1992;267:1100-1105)
The Hot Clot Sign: A New Finding in Deep Venous Thrombosis on Bone Scintigraphy
Authors: L S ZUCKIER, K A PATEL, J P WEXLER, A D BLAUFOX, R COHEN
Journal: Clinical Nuclear Medicine (1990)

Focal Tc-99m MDP uptake on bone scanning in regions of deep venous thrombosis (DVT) is reported in two patients with documented DVT. It is speculated that this uptake may be related to localized calcification or ossification, which is occasionally observed on radiographs of patients with chronic DVT.

Allergic Bronchopulmonary Aspergillosis
Authors: B. A. Cockrill, MD, C. A. Hales, MD
Journal: Annual Review of Medicine (1999)

Allergic bronchopulmonary aspergillosis (ABPA) is a syndrome seen in patients with asthma and cystic fibrosis. It is characterized by chronic colonization of the airways with a ubiquitous fungus, Aspergillus fumigatus. The clinical expression of ABPA results from the complex interaction of chronic colonization of the airways with A. fumigatus, host factors allowing this colonization, and the host's genetically determined immune response. Clinically the syndrome is characterized by recurrent episodes of wheezing, mucus production, pulmonary infiltrates, and elevated levels of serum IgE. Many patients develop central bronchiectasis, and a subset will go on to end-stage fibrotic lung disease. It is thought that treatment will prevent this progression. The mainstay of therapy remains oral corticosteroids.

Psychological assessment of therapy in coronary artery disease
Authors: J. S. Pearson
Journal: JAMA (1971)

Psychologic assessment was attempted preoperatively and postoperatively in 19 patients who had cardiac revascularization. Results suggest that there is some validity in the common stereotype of the personality of the patient with myocardial ischemia as tense, striving, and overcontrolled. Two disparate modes of reacting to the threat of surgery may be distinguished—one of overt depression and anxiety, the other of hysteroid denial. Also postoperatively, two different responses were observed—placebo effect and psychologic disability.
Environmental Tobacco Smoke Exposure and Asthma in Adults
Authors: Scott T. Weiss, Mark J. Utell, Jonathan M. Samet
Journal: Environmental Health Perspectives (1999)

Environmental tobacco smoke (ETS) contaminates indoor air in homes and workplaces.Although the adverse effects of active cigarette smoking on the respiratory tract have been extensively characterized, the effects of ETS exposure on adult asthma have not yet been investigated extensively and the available data are limited.This article examines the evidence for ETS exposure as a cause of asthma and asthma exacerbation in adults, and for ETS exposure in the workplace specifically as contributing to these health effects.It addresses methodological barriers that limit the available data and evaluates the adequacy of the data for risk assessment.

patients suffered severe bacterial or opportunistic infections; serum immunoglobulin levels remained within the normal limits during treatment in all cases.Our preliminary results suggest that rituximab seems to be a useful therapeutic alternative in patients with active SOJIA in whom previous treatments (including TNFa antagonists and anakinra) have failed.Our experience is that rituximab produces a substantial clinical improvement (remission of the systemic symptoms and moderate European League Against Rheumatism response of the arthritis), although the disease does not enter into remission.Of interest, our experience with rituximab is similar to the French experience with IL-1 receptor antagonist treatment in SOJIA/adult-onset Still's disease. 6In that study, the benefits with anti-IL-1 therapy seem to be fair in the systemic manifestations but reduced in the articular complaints.Further studies are needed to determine the place of specific B-cell depletion in the treatment of refractory SOJIA.

Childhood poisoning accidents
Authors: H. L. Verhulst
Journal: JAMA (1968)

From 500,000 to 2 million American children accidentally ingest potentially toxic materials every year, and approximately 500 children under 5 year of age die as a result. Although these incidents are called accidental poisonings they are, more correctly, poisoning accidents. Ninety percent of the reports to the National Clearinghouse involve children under the age of 5 who have ingested products that are commonly found in and around the house. From the reports submitted annually to the National Clearinghouse, it is known that these substances are medicines in approximately one half of the cases and household products in the other half. Approximately one fourth of the total problem is due to the ingestion of aspirin (88% due to 0.08-gm [1 1/4-grain] tablets, 12% due to 0.3-gm [5-grain] tablets); thus the number of cases in which aspirin is involved roughly equals the number involving all other internal medicines.

Fruitful metabolism of error
Authors: S. Vaisrub
Journal: JAMA (1977)

When T. S. Eliot wrote, "The last temptation is the greatest treason:/To do the right deed for the wrong reason" (<i>Murder in. the Cathedral</i>), he clearly did not have in mind the scientific investigator. To the moral philosopher, motivation may be paramount, but to the scientist, the important thing is the result—the deed—regardless of the reason that prompted it. Many important scientific breakthroughs have been made in the course of research inspired by wrong reasons. False notions of astrology led to major discoveries in astronomy. Futile pursuits of alchemy paved the way to achievements in modern chemistry. In this century, Domagk's discovery of the effectiveness of Prontosil against streptococci was a "deed" of the utmost benefit, yet the underlying assumption was false. The colorless part of the molecule, sulfanilamide, rather than the red dye held by Domagk to be the active agent, was responsible for the antibacterial action. A long
The scientific basis for coverage decisions by third-party payers
Authors: O. B. Towery
Journal: JAMA (1981)

Each third-party health payer has its own method of determining which medical services should be covered. The new National Center for Health Care Technology (NCHCT) is charged with evaluating the medical and scientific basis for Medicare coverage of various tests and procedures used in the practice of medicine. Many of the important issues involved in performing these evaluations and the NCHCT approach are described in this article. (<i>JAMA</i>1981;245:59-61)

Silver Stools
Authors: Robert H. Wilbee
Journal: JAMA (1981)

<h3>To the Editor.—</h3> As another (and perhaps, final) contribution to the ongoing saga (1979;242:2433, 1980;243:1809, 1980;244:1437), I must report that the 1960 edition of Hamilton Bailey's classic book<sup>1</sup>unmistakably describes the silver stool and goes on to observe that it "is fairly characteristic of carcinoma of the ampulla of Vater." I am aware of this only because such a case was presented on ward rounds many years ago when I was a junior resident. Having just read the aforementioned section, I triumphantly provided the diagnosis, noting that this distinctive finding was unique to patients with concomitant biliary obstruction and gastrointestinal bleeding. This knowledge was sealed forever in my memory when we learned, one week later, that exploratory surgery had disclosed the patient suffered from an obstructing common duct stone and a bleeding peptic ulcer.
