Abstract

The effects of piscicides on aquatic invertebrates are often studied after one treatment, even though piscicides may be repeatedly applied within river management. Here we investigate the impacts of repeated piscidie treatment on riverine benthic invertebrates. The River Ogna, Norway, was treated with rotenone three times over a 16-month period. The two first treatments caused temporary density reduction of a few rotenone sensitive benthic invertebrate taxa. Effects of the third treatment were variable with some taxa unaffected while all Plecoptera, were locally extinct. The toxic effect of rotenone increases with water temperature and high water temperature (20 °C) combined with high rotenone concentration was probably the main reason why the benthic community in the third treatment was more negatively affected than during the two previous treatments (4 and 8 °C). Eight months after the treatment benthic densities had not reached pre-treatment levels, but most taxa had recolonized the treated area within a year. Our data suggest that the severe effects of the third treatment were not influenced by the two former ones. This implies that the timing of piscicide treatment has a greater impact on the benthic invertebrate community than the number of treatments. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract

Treelines differentiate vastly contrasting ecosystems: open tundra from closed forest. Treeline advance has implications for the climate system due to the impact of the transition from tundra to forest ecosystem on carbon (C) storage and albedo. Treeline advance has been seen to increase above-ground C stocks as low vegetation is replaced with trees, but decrease organic soil C stocks as old carbon is decomposed. However, studies comparing across the treeline typically do not account for elevational variation within the ecotone. Here we sample ecosystem C stocks along an elevational gradient (970 to 1300m), incorporating a large-scale and long-term livestock grazing experiment, in the Southern Norwegian mountains. We investigate whether there are continuous or discontinuous changes in C storage across the treeline ecotone, and whether these are modulated by grazing. We find that vegetation C stock decreases with elevation, with a clear breakpoint between the forest line and treeline above which the vegetation C stock is constant. In contrast, C stocks in organic surface horizons of the soil increase linearly with elevation within the study's elevational range, whereas C stocks in mineral soil horizons are unrelated to elevation. Total ecosystem C stocks also showed a discontinuous elevational pattern, increasing with elevation above the treeline (8 gm-2 m-1 increase in elevation), but decreasing with elevation below the forest line (-15 gm-2 m-1 increase in elevation), such that ecosystem C storage reaches a minimum between the forest line and treeline. We did not find any effect of short-term (12 years) grazing on the elevational patterns. Our findings demonstrate that patterns of C storage across the treeline are complex, and should be taken account of when estimating ecosystem C storage with shifting treelines.

Abstract

Introduction: Delirium is a common manifestation of acute illness, characterised by fluctuating changes in mental state. Its aetiologies and presentations are diverse. This can lead to underdiagnosis. We screened all adult inpatients at Barnet Hospital for delirium. 20 weeks follow-up data was collected, including mortality and admission to institutional care. Methods:The 4AT and Clinical Frailty Score (CFS) were recorded for every adult inpatient (n=220) in Barnet Hospital on 13/03/2019. Hospital notes were reviewed to establish whether delirium assessments were performed during admission. Electronic records were used to establish length of stay, discharge destination, mortality and readmission rate over 20 weeks. Results: 30% (n=65) of inpatients had possible delirium (4AT score≥4). Delirium was more common in older, frailer patients (Table 1). Most patients with delirium were under the care of geriatric (40%) or acute medicine (26%). Only gastroenterology and gynaecology had no patients with delirium. Patients with delirium were 3 times more likely to die during their admission and were twice as likely to be discharged to institutional care (Table 1). 20 week mortality of patients with delirium was 26%. Conclusion: Delirium is common in hospital inpatients. Delirium has a high morbidity and mortality. Better diagnosis of delirium in hospital may improve outcomes.

88. SYNOVECTOMY OF THE KNEE JOINT

Author

SPEED, J. S.

Abstract

Synovectomy as a surgical procedure to relieve various affections of the knee joint dates back at least as far as 1877, when the German surgeon Volkmann employed it in the treatment of tuberculosis of the knee joint. During the next twenty years, the operation was used quite extensively in the treatment of this condition, and there was considerable discussion as to the relative merits of synovectomy and excision of the knee joint. It was apparently not used in the infectious types of arthritis until 1895, when Albertin1 reported two cases of synovectomy for acute infectious arthritis following penetrating wounds of the knee. The first record found of a synovectomy in chronic arthritis is an article by Mignon,2 in 1900, in which he reports the removal of the entire synovial membrane from the anterior compartment of the knee in a case of chronic traumatic arthritis with hydrops of the

89. RECONSTRUCTION OPERATION ON THE HIP

Author

SPEED, J. S.

Abstract

As the operative reconstruction of the hip joint has been developed, its use has broadened to include so many clinical conditions that it is manifestly impossible to cover all of the subjects in a paper of this type. Consequently, only the following conditions, which seem to be the most interesting and which perhaps have the broadest field of application, will be discussed:Congenital dislocation of the hip which cannot be reduced or cannot be held within the acetabulum after reduction.Paralytic dislocations in connection with poliomyelitis which completely dislocate or partially subluxate, giving an unstable hip.Ununited fractures of the neck of the femur after the possibility of bony union has passed.Much interesting work is being done in connection with other conditions, such as the painful hips in hypertrophic arthritis, unreduced traumatic dislocations and the pathologic dislocations associated with destructive lesions of the hip joint.Arthroplasties of the hip,

90. TREATMENT OF FRACTURES OF ULNA WITH DISLOCATION OF HEAD OF RADIUS: (MONTEGGIA FRACTURE)

Author

SPEED, J. S. and BOYD, HAROLD B.

Abstract

Fracture of the ulna associated with dislocation of the head of the radius was described by Monteggia in 1814 and is often called by his name. During the past twelve years thirty-four articles dealing with this subject have appeared in the literature, and of these only two have been in English. The fact that the lesion is difficult to treat and the end results are often disappointing may account for the paucity of English literature on the subject.The present study is based on a series of sixty-two injuries of this type which have been treated by the members of the staff of the Willis C. Campbell Clinic. Thirty of the patients had acute fractures, ten of which were compound. The remaining thirty-two patients had old injuries, having been first seen four weeks or longer after the accident.The dislocation of the head of the radius was anterior in 83

91. LIVER FUNCTION AS INFLUENCED BY ANESTHETICS AND NARCOTICS

Author

Whipple, G. H. and Speed, J. S.

Abstract

It has been established that specific liver poisons (chloroform, phosphorus) which cause histological changes in the liver cells, decrease the liver excretion of phenoltetrachlorphthalein. Also vascular disturbances (Eck fistula, passive congestion) with or without histological evidence may cause a fall in the output of phthalein through the liver. Sufficient evidence has been brought forward to show that the phenoltetrachlorphthalein excretion is a valuable index concerning the functional capacity of the liver. Ether anesthesia for a period of two hours usually causes a depression in the phthalein curve during the twenty-four hours following the anesthesia. Paraldehyde in doses sufficient to give anesthesia and stupor for a few hours will give adefinite fall in phthalein excretion. Chloral and urethane usually cause a decrease in phthalein output when given in considerable amounts. Alcohol causes a drop in the phthalein curve when given in large doses sufficient to cause stupor for a few hours. The drop in phenoltetrachlorphthalein excretion is demonstrated in the twenty-four hours following administration of the drug. A drop in the phthalein curve to two-thirds or one-half of normal indicates a definite liver injury and temporary impairment of function.

92. CENTRAL FRACTURES OF THE NECK OF THE FEMUR: AN ANALYSIS OF THE END RESULTS

Author

SPEED, J. S.

Abstract

A great deal of confusion still exists in regard to the results obtained in the treatment of central fractures of the neck of the femur. This is unquestionably the result of a lack of uniformity in the methods of compiling the statistics and explains the otherwise impossible disparity in the published results, which vary from 20 to 90 per cent in which bony union is obtained. In other words, for figures to be of value one must know exactly how the cases were selected, under what circumstances they were treated and on what criteria the assumption of bony union was determined.It is fairly well conceded that the reports of end results in central fractures of the femoral neck which are properly and accurately compiled average about from 55 to 60 per cent solid bony union.My colleague Dr. Willis C. Campbell has recently compiled an analysis of all our

93. ARTHROPLASTY OF THE KNEE

Author

Speed, J. S. and Trout, Philip C.

Abstract

1. Arthroplasty of the knee joint should be performed only in carefully selected cases. Criteria for the operation are outlined.2. In our experience, 70 per cent. of properly selected patients secure good or fair results. An additional 12 per cent., whose anatomical or functional results were classified as poor, preferred the movement which had been gained to ankylosis of the joint.3. The major functional adaptation of the knee joint takes place during the first five years after arthroplasty. Several patients who had a poor range of movement after one or two years developed an excellent range by the end of five years.4. Instability, when present, usually became apparent within the first five years.5. Joints which were still stable at the end of five years usually remained so over a long period of time. Four patients have been traced for twenty to twenty-five years, and three have been traced for over twenty-five years.6. Since the incidence of ankylosis of the knee joint from gonococcal and pyogenic infections has been reduced by the use of antibiotics, fewer patients are suitable subjects for arthroplasty.
