    Notes: Abstract During an 8-year period, 238 barium double-contrast studies performed in 162 patients with continent ileostomy reservoirs who had signs and symptoms of late complications (malfunction of the valve, non-specific inflammation of the mucosa, stenoses, hernias, and fistulas) showed radiologic abnormalities. The aim of the present study is to depict the radiologic findings in patients with late complications of continent ileostomy reservoirs. With radiologic examination, the correct diagnosis of valve malfunction was made in 96% of patients with surgically proven valve defects. We were able to differentiate between various types of valve dysfunction and complications related to the fixation of the reservoir to the abdominal wall. Inflammatory mucosal changes and fistulas of the reservoir and the afferent ileal segment were depicted with a high degree of accuracy. Barium double-contrast radiologic examination proved to be very valuable in the work-up of patients with dysfunction of continent ileostomy reservoirs. The method was of particular value in assessing the cause of valve dysfunction and in the appraisal of the afferent ileal segment.

    Blood pressure response to administration of local anaesthetics with noradrenaline in craniotomies (1980)

    Notes: Summary Infiltration with local anaesthetics with addition of adrenaline or noradrenaline has been used since 1910 prior to skin incision for craniotomy. In a controlled series of patients scheduled for intracranial operations, systemic blood pressure was measured intra-arterially after infiltration with 15–20 ml 0.5% lignocaine with noradrenaline 1 μ gr/ml. A marked increase in systemic blood pressure was seen (125% of values prior to infiltration). In a control series, where saline was injected, a slight fall in blood pressure was registered (p〈 0.01). As hypertensive episodes increase intracranial pressure in patients with impaired cerebral autoregulation, or promote the risk of haemorrhage in aneurysm surgery, this technique is considered a hazard to patients undergoing intracranial operations.

    Radiology of the continent ileostomy reservoir: I. Method of examination and normal findings (1994)

    Notes: Abstract The aim of the present study is to describe the radiologic methods used to study continent ileostomy reservoirs and to depict the normal radiologic features and variations identified by these procedures. During an 8-year period, 408 double-contrast studies were performed in 261 patients. The present study comprises 170 examinations in 99 patients with normal findings. A high-density barium contrast medium and air were used. Modest variation in the size and shape of the reservoirs was observed. The mucosal pattern of the reservoirs resembled that of the ileum but the folds were slightly wider. The continence-providing valves were 3–5 cm long and had a diameter of 2.5–4.0 cm. The diameter of the afferent ileal segments was usually slightly larger than that of more proximal ileal segments, with an upper limit of approximately 4 cm. The efferent ileal segments generally had a straight course without widening or outpouches. Retrograde barium double-contrast examination is a satisfactory method for the evaluation of continent ileostomy reservoirs. Here we define the range of normal variations of such reservoirs as seen on retrograde double-contrast radiologic examinations.

    Stress Urinary Incontinence at Rest (1999)

    Notes: Abstract: We retrospectively identified 37 cases in which urinary incontinence occurred at rest during urodynamic testing in the absence of a coincident detrusor contraction or urethral relaxation. This phenomenon, genuine stress incontinence at rest, was observed during 9.6% of multichannel cystometrograms performed at our institution. The observed urine loss occurred at bladder volumes between 145 ml and 800 ml. Loss occurred with bladder overdistension (overflow incontinence) in only 3 subjects (8%). Decreased bladder compliance was observed in 11 (30%) and decreased outlet resistance was demonstrated in 24 (65%). Our findings suggest that genuine stress incontinence at rest is relatively common in a referred population of incontinent women. This phenomenon is associated with impaired urethral function and/or decreased bladder compliance.

    Federal guidelines for the management of urinary incontinence in the United States: Which patients should undergo urodynamic testing? (1995)

    Notes: Abstract In 1992, the United States Agency for Health Care Policy and Research (AHCPR) proposed a guideline for the management of adults with urinary incontinence. The purpose of this study is to evaluate the criteria proposed by the AHCPR for the selective use of urodynamic testing in women complaining of stress incontinence. In order to examine the efficacy of these criteria, we retrospectively determined urodynamic diagnoses for 101 women presenting with the complaint of stress incontinence. These were then compared to the AHCPR recommendations for each subject's management. We found that the AHCPR algorithm would have recommended treatment without urodynamic testing for 65% of the population. If the AHCPR guideline had been followed, 32% of the overall population could have received inappropriate treatment. These results suggest that the implementation of the AHCPR guideline could result in inappropriate treatment for onethird of women presenting with symptoms of stress incontinence.

    Notes: Abstract A unique integrated modelling system has been developed and applied for environmental assessment studies in connection with the Gabcikovo hydropower scheme along the Danube. The modelling system integrates model codes for describing the reservoir (2D flow, eutrophication, sediment transport), the river and river branches (1D flow including effects of hydraulic control structures, water quality, sediment transport), the ground water (3D flow, solute transport, geochemistry), agricultural aspects (crop yield, irrigation, nitrogen leaching) and flood plain conditions (dynamics of inundation pattern, ground water and soil moisture conditions, and water quality). The uniqueness of the established modelling system is the integration between the individual model codes, each of which provides complex descriptions of the various processes. The validation tests have generally been carried out for the individual models, whereas only a few tests on the integrated model were possible. Based on discussion and examples, it is concluded that the results from the integrated model can be assumed less uncertain than outputs from the individual model components. In an example, the impacts of the Gabcikovo scheme on the ecologically unique wetlands created by the river branch system downstream of the new reservoir have been simulated. In this case, the impacts of alternative water management scenarios on ecologically important factors such as flood frequency and duration, depth of flooding, depth to ground water table, capillary rise, flow velocities, sedimentation and water quality in the river system have been explicitly calculated.
