The authors failed to mention, however, a useful and readily available technique for diagnosing deep venous thrombosis of the lower extremity, namely, nuclear venography. Because lung perfusion scanning can be done by injecting macroaggregated albumin through any peripheral vein, one can inject the tracer through veins in the feet and image the deep venous system as the tracer travels to the lungs.

"Authorship cannot be conferred; it may be undertaken by one who will shoulder the responsibility that goes with it."<sup>1</sup> Scientists who become authors display a rich variety of publication habits. Isaac Newton was famously reluctant to publish and, when he did, to attach his name to the work.<sup>2</sup>More recently, and less famously, Yury Struchkov published one paper every 3.9 days for 10 years, while 20 researchers worldwide each published at least once every 11.3 days throughout the decade of the 1980s.<sup>3</sup> See also p 438. Whichever strategy is employed, the product of research is embodied in a manuscript that, once published, allows others to try to replicate and extend the work. Scientists believe they invest their lives in their research and in each manuscript. The published paper, though ostensibly merely a means of communication, is tangible evidence of this intellectual effort. Research workers, expecting to see

Future advances in ultrasonography will undoubtedly occur in three major areas: diagnostic capability, instrumentation, and clinical applications. In the area of diagnostic capability, spatial and contrast resolution offer excellent opportunities for improvement. Continued research into tissue characterization is worthwhile, even though efforts to date have been more frustrating than fulfilling. Blood flow studies and new contrast agents are among the more promising areas for future development. New techniques of signal detection, analysis, and display in Doppler imaging may overcome some present limitations, including those in color flow imaging.
Occult AIDS.

<h3>Abstract</h3> This paper uses constructs from machine learning to define pairs of learning tasks that either shared or did not share a common subspace. Human subjects then learnt these tasks using a feedback-based approach. We found, as hypothesised, that subject performance was significantly higher on the second task if it shared the same subspace as the first. Additionally, accuracy was positively correlated over subjects learning same-subspace tasks, and negatively correlated for those learning different-subspace tasks. These results were compared to the behaviour of a Neural Network model trained using sequential Bayesian learning. Human performance was found to be consistent with a minimal capacity variant of this model. Networks with an increased representational capacity, and networks without Bayesian learning, did not show these transfer effects. We propose that the concept of shared subspaces provides a useful framework for the experimental study of human multitask and transfer learning. <h3>Author summary</h3> How does knowledge gained from previous experience affect learning of new tasks ? This question of “Transfer Learning” has been addressed by teachers, psychologists, and more recently by researchers in the fields of neural networks and machine learning. Leveraging constructs from machine learning, we designed pairs of learning tasks that either shared or did not share a common subspace. We compared the dynamics of transfer learning in humans with those of a multitask neural network model, finding that human performance was consistent with a minimal capacity variant of the model. Learning was boosted in the second task if the same subspace was shared between tasks. Additionally, accuracy between tasks was positively correlated but only when they shared the same subspace. Our results highlight the roles of subspaces, showing how they could act as a learning boost if shared, and be detrimental if not.
Hepatic venular stenosis after orthotopic liver transplantation
Authors: A Dhillon
Journal: Hepatology (1994)

Fibrous stenosis of hepatic venules and other features of venous outflow obstruction, including zone 3 congestion and hemorrhage, are sometimes seen after orthotopic liver transplantation. Similar changes associated with endothelial damage have recently been ascribed to azathioprine toxicity and may be forerunners of chronic rejection. Other potential causative agents such as viral hepatitis have yet to be considered. We reviewed 49 liver biopsy specimens from 21 consecutive patients after orthotopic liver transplantation, in whom full data including further follow-up biopsy samples were available. Hepatic venous stenosis was identified in seven patients who had received azathioprine and two additional patients in whom this change could not be ascribed to azathioprine. Stenosis was always associated with zone 3 hemorrhage and congestion and was first noted between 5 and 30 days after transplantation in all but two cases; in these two patients they were first noted after 72 and 133 days. Cellular rejection, including endotheliitis involving terminal hepatic venules, was found in five of the seven patients who had received azathioprine. Chronic (ductopenic) rejection was not seen during a follow-up period of between 97 and 540 days. In three of the nine patients with hepatic venular stenosis, zone 3 changes persisted, and in two of these azathioprine could not be held responsible. Of the 12 patients without hepatic venular stenosis, 10 had received azathioprine. Two of these 12 patients had peliosis-like foci but no other vascular abnormalities. Both also had moderate cellular rejection. Hepatic venular stenosis was found in 43 of patients after liver transplantation; this was usually associated with azathioprine administration and concomitant cellular rejection. Hepatic venular stenosis was usually transient despite continued azathioprine administration. Transient hepatic venular stenosis could be caused by endothelial damage associated with endotheliitis in terminal venules as part of the process of cellular rejection. Rejection frequently coincides with azathioprine administration. Other causative agents such as recurrent viral hepatitis are required to explain persistent hepatic venular stenosis.

What causes road accidents?
Journal: BMJ (1978)

The cost of treating victims of road accidents in England and Wales was estimated at between J50m and £55m in the financial year 1977-8; 1-4°,, of all hospital beds were taken up by these patients.1In 1977 the total estimated cost of road accidents in Great Britain, including the "damage only" category and including an allowance for lost output, was £940m.2To this the Department of Transport adds an allowance for "pain, grief, and suffering," amounting to C347m.This it calls a notional and minimum value.

Constipation

Journal: Gut (1995)

EDITOR,-Eighteen coeliac patients and nine control patients in our study suffered from autoimmune thyroid diseases.We included all patients who had a past history of autoimmune thyroid disease.It is possible that the increased frequency among coeliac patients is real, even though the difference was not statistically significant.The findings of Counsell et al suggest that the association between these diseases is more than coincidental.Supporting this, in another study that we conducted, four (4/8%) of 83 patients with autoimmune thyroid disease had silent coeliac disease, when they were screened by the IgA reticulin and gliadin antibody tests.1It is correct that we did not search for autoimmune thyroid diseases vigorously among either coeliac patients or control patients.Some cases may have remained undiagnosed in both groups.We consider that prospective controlled studies would be essential to confirm the association between these diseases.We agree with Counsell et al that thyroid function should be examined in all coeliac patients.Nowadays we also screen all patients with autoimmune thyroid diseases by retic- ulin and gliadin antibody tests.
Comparison of the incidence, nature and cause of injuries sustained on grass and new generation artificial turf by male and female football players. Part 2: training injuries
Authors: Colin W Fuller, Randall W Dick, Jill Corlette, Rosemary Schmalz
Journal: British Journal of Sports Medicine (2007)

To compare the incidence, nature, severity and cause of training injuries sustained on new generation artificial turf and grass by male and female footballers.The National Collegiate Athletic Association Injury Surveillance System was used for a two-season (August to December) prospective study involving American college and university football teams (2005 season: men 52 teams, women 64 teams; 2006 season: men 54 teams, women 72 teams). Injury definitions and recording procedures were compliant with the international consensus statement for epidemiological studies of injuries in football. Athletic trainers recorded details of the playing surface and the location, diagnosis, severity and cause of all training injuries. The number of days lost from training and match play was used to define the severity of an injury. Training exposures (player hours) were recorded on a team basis.The overall incidence of training injuries for men was 3.34 injuries/1000 player hours on artificial turf and 3.01 on grass (incidence ratio 1.11; p = 0.21) and for women it was 2.60 injuries/1000 player hours on artificial turf and 2.79 on grass (incidence ratio 0.93; p = 0.46). For men, the mean severity of injuries that were not season ending injuries was 9.4 days (median 5) on artificial turf and 7.8 days (median 4) on grass and, for women, 10.5 days (median 4) on artificial turf and 10.0 days (median 5) on grass. Joint (non-bone)/ligament/cartilage and muscle/tendon injuries to the lower limbs were the most common general categories of injury on artificial turf and grass for both male and female players. Most training injuries were acute (men: artificial turf 2.92, grass 2.63, p = 0.24; women: artificial turf 1.94, grass 2.23, p = 0.21) and resulted from player-to-player contact (men: artificial turf 1.08, grass 0.85, p = 0.10; women: artificial turf 0.47, grass 0.56; p = 0.45).There were no major differences between the incidence, severity, nature or cause of training injuries sustained on new generation artificial turf and on grass by either men or women.

Epidemiological and Experimental Aspects of Metal Carcinogenesis: Physicochemical Properties, Kinetics, and the Active Species
Authors: Laszlo Magos
Journal: Environmental Health Perspectives (1991)

The carcinogenic properties of selected metals and their compounds are reviewed to provide a useful reference for existing knowledge on relationships between physical and chemical forms, kinetics and carcinogenic potential and between epidemiology, bioassays, and short-term tests. Extensive consideration is given to arsenic, beryllium, cadmium, chromium, lead, and nickel. Other metals such as antimony, cobalt, copper, iron, manganese, selenium, and zinc are discussed briefly.
A six-year follow-up of HIV-infected homosexual men with lymphadenopathy. Evidence for an increased risk for developing AIDS after the third year of lymphadenopathy
Authors: J. E. Kaplan
Journal: JAMA (1988)

Seventy-five homosexual men with generalized lymphadenopathy for at least three months (lymphadenopathy syndrome [LAS]), subsequently shown to be seropositive for antibody against human immunodeficiency virus, were enrolled in a prospective study in Atlanta in 1982 and 1983. As of Nov 30,1987, twenty-two (29%) of the 75 were known to have developed acquired immunodeficiency syndrome (AIDS) three to 60 months after enrollment and five to 69 months after onset of LAS. The six-year cumulative incidence of AIDS, by Kaplan-Meier survival analysis, was 38%. The cumulative incidence in years 4,5, and 6 (30%) was significantly higher than in years 1, 2, and 3 (11%), suggesting that the risk for AIDS increases after the third year of LAS and that many more study participants will eventually develop AIDS. A precipitous decline in the T-helper cell count frequently heralds the diagnosis of AIDS; this decrease appears to occur at different times after the onset of LAS in different persons. The four-year cumulative incidence of AIDS following observations of T-helper cell counts less than 200/mm<sup>3</sup>, 200 to 299/mm<sup>3</sup>, 300 to 399/mm<sup>3</sup>, and 400/mm<sup>3</sup>or greater was 84%, 41%, 25%, and 18%, respectively; these data are important for determining prognosis in the individual patient as well as for determining the suitability of candidates and baseline data for drug trials.

Algorithmic method for assessing urinary incontinence in elderly women.
Journal: BMJ (1981)

In young patients the assessment of urinary incontinence is based increasingly on the results of complex uro- dynamic investigations.The value of such techniques in the elderly, however, is as yet unproved.Based on the clinical and urodynamic findings in 100 incontinent elderly women an algorithmic method for managing such patients was devised.A retrospective study com- paring the algorithmic outcome with the results of standard urodynamic assessment showed that 60% of invasive investigations could be avoided by this method with minimal loss of diagnostic accuracy.
Premature concerns for cesarean sections?
Authors: M. G. Rosen
Journal: JAMA (1984)

The article by Gleicher<sup>1</sup>in this issue ofThe Journalonce again documents the very important need to continue to evaluate the high rates of cesarean births while maintaining improved outcomes. Dr Gleicher suggests that even at this early date, the Consensus Development Conference should have resulted in altered obstetrical practices. For several reasons I suggest that this argument may have been prematurely raised. The Consensus Development Conference on Cesarean Child-birth was held from Sept 22 to 24, 1980. The audience at that time was approximately 300 persons. At least half of those present were members of the lay press and nonobstetricians who had concerns with the problem of high cesarean birth rates. Thus, the educable audience was indeed limited. The first reports of the conference were published in two major obstetrical journals<sup>2,3</sup>in April 1981. Finally, the official conference document was published in October 1981. If we
