    Depression in the low-latitude horizontal intensity due to quiet-time ring current (1971)

    Notes: Summary The external field due to plasma within the magnetosphere has been computed as a function ofA p, which is a measure of solar wind velocity, for very quiet to slightly disturbed conditions using mean daily horizontal intensity from 1932 to 1968 at Alibag. The intensity, corrected for secular change and reduced to a common epoch, showed initially a small increase withA p followed by a steady depression with further increase in the index. ForA p∼7.5, which is representative of conditions over the 33-hour interval during which data relating to low-energy protons were acquired and used byHoffman andBracken [4]2) to compute current distributions, the decrease, computed here from surface data, is 6 γ. This is in goodagreement with the southward directed field of the quiet-time proton belt 9±5 γ obtained byHoffman andBracken.

    Pseudoaneurysm of the superficial femoral artery following accidental trauma: result of treatment by percutaneous stent-graft placement (1999)

    Notes: Abstract. Accidental trauma frequently involves the extremities, and can extend to involve their blood supply, causing exsanguinating hemorrhage and pseudoaneurysm in the involved blood vessel. This is traditionally managed by surgical repair. We report a case in which control of life-threatening hemorrhage and exclusion of a large, post-traumatic pseudoaneurysm in the superficial femoral artery was performed by a commercially available stent-graft, without complication. This treatment method may be a safe and effective alternative to surgery in selected patients.

    Utility of coaxial technique for renal angioplasty in patients with a difficult-to-cross stenosis (1999)
    Springer

    Notes: Abstract. The aim of this study was to evaluate the feasibility of coaxial approach in difficult-to-cross lesions in patients with failed percutaneous transluminal renal angioplasty by conventional over-the-wire exchange technique. Twelve stenoses in 10 patients (six women and four men; age range 19 ± 7 years) with uncontrolled hypertension were treated by this method. The stenosis was caused by nonspecific aortoarteritis in 8 patients and fibromuscular dysplasia in 2 patients. It was ostial in seven and post-ostial in five vessels. Conventional exchange technique was unsuccessful in all of them. All procedures were done by femoral route. Technical success was seen in 11 (92 %), without complication. The stenosis improved from 90 ± 2.1 % (range 80–100 %) to 6 ± 7 % (range 0–20 %), blood pressure decreased from 198 ± 12.3 mm Hg (range 180–220 mm Hg)/130 ± 6.7 mm Hg (range 120–140 mm Hg) to 119 ± 5.7 mm Hg (range 110–130 mm Hg)/83 ± 3.9 mm Hg (range 80–90 mm Hg), and number of drug treatments for hypertension fell from 3.6 ± 0.52 (range 3–4) to 1 ± 0.94 (range 0–3; p 〈 0.01). Percutaneous transluminal renal angioplasty resulted in “cure” in 3 patients and “improvement” in 7 patients. Follow-up period was 3–21 months (mean 6.4 months). No restenosis was detected. Coaxial approach is safe and effective in treating difficult-to-cross lesions in which renal angioplasty by conventional exchange technique is unsuccessful.

    Notes: [Auszug] We have studied the recurrence tendency of geomagnetic activity for the three-year period 1950-53. A plot of three-day running means of the international magnetic character figures C for this period indicates that sequences of magnetic activity last much longer than has been thought hitherto.

    Recurrent magnetic activity, sunspot number and its rate of decline (1975)

    Notes: Abstract Power spectral densities computed from low-latitude horizontal intensity of the Earth's magnetic field over two-year periods of declining phases of solar cycles 16 to 19 show a close relationship with the maximum relative sunspot number of the following solar cycles. The maximum sunspot number shows an exponential rise with the power density near 1/27 cd−1; maximum R z,however, increases linearly with power density near 1/14 cd−1. It is also shown that the rate of decline of sunspot number in a solar cycle is almost exactly related, linearly, to power spectral density for the preceding solar cycle. Power densities near 1/27 and 1/14 cd−1 in declining phase of solar cycle appear to be satisfactory indices for the maximum relative sunspot number of the following cycle and its rate of decline thereafter.

    Notes: Abstract Malignancy accounts for 40%–60% of pericardial effusions. Two individuals with malignant pericardial effusions secondary to lung cancer, managed with the help of a percutaneous balloon pericardial window (PBPW), are discussed in this report. Clinical benefits in terms of reduction of breathlessness and improved diastolic function of the heart were documented in both. There were no procedure-related complications. The PBPW provides quick relief, appears diagnostically superior to an invasive technique and has a low rate of recurrence and complications.
