    Notes: In this study, we examined the usefulness of the earlobe crease sign as a marker of coronary artery disease in the pre-operative assessment of patients. We were interested in evaluating this sign for use in emergency patients. We investigated 530 patients, aged 〉 40 years, undergoing elective surgery. If the electrocardiogram was abnormal or the patient reported symptoms suggesting coronary artery disease, further cardiac examinations were performed. Patients who demonstrated evidence of coronary artery disease in the additional investigations or had a clear history of coronary artery disease were classified as the abnormal coronary group. Other patients with no history and/or normal investigations were classified as the normal coronary group. The assessment of earlobe crease sign was performed prior to anaesthesia, and the sensitivity, specificity and positive predictive value of this sign were calculated. We found that the sensitivity and specificity was high regardless of age, except for specificity in patients 〉 70 years old. The data suggest that the earlobe crease sign may be a useful marker for the presence of coronary artery disease in patients undergoing emergency operations in which little or no history and investigations are available. However, more work is required to assess the use of this sign in other ethnic groups.

    Notes: Abstract We report a patient with lung cancer associated with psoas abscess-like metastasis and humoral hypercalcemia of malignancy (HHM). A 71-year-old man was hospitalized with exacerbating pain on the left-side of his back and thigh. A computed tomography (CT) scan of the abdomen demonstrated a tumor in the left iliopsoas muscle, first diagnosed as psoas abscess. A chest roentgenogram showed right-sided pleural effusion, and CT scan of the chest demonstrated a tumor in the right lower lobe of the lung. His serum calcium level was 12.8 mg/dl, and parathyroid hormone-related protein (PTH-rP) level was elevated, to 11.1 pmol/l. The patient died of progressive disease, and necropsy specimens were diagnosed as poorly differentiated squamous cell carcinoma. Immunohistochemical staining for PTH-rP was positive in the tumor cells, including the primary and the metastatic lesions. A review of this unusual tumor type is also presented.

    Some physical properties of amorphous SiO2 synthesized by shock compression of α quartz (1980)

    Notes: Abstract The amorphous phase of SiO2 produced upon recovery of shock-compressed quartz demonstrates a wide range of refractive indices which can be correlated to the shock state. Both infra-red absorption spectra and X-ray diffraction patterns indicate that the shock-produced amorphous SiO2 has a statistically more-random atomic distribution and longer Si-O and shorter Si-Si separation than does fused silica. By accounting for phase transformation, the calculated values of the shock and residual temperature are much higher than those obtained by Wackerle (1962) to a pressure of 700 kbar. Our results are consistent with experimental ones.

    Measurements of energy correlations ine + e −→hadrons (1984)

    Notes: Abstract Energy-energy-correlations (EEC) have been measured with the JADE detector at c.m. energies of 14 GeV, 22 GeV and in the region 29 GeV〈E cm〈36 GeV. Corrected results are presented of EEC and their asymmetry, which can be directly compared to theoretical predictions. At 〈E cm〉=34 GeV a comparison with second order QCD predictions yields good agreement for the string model fragmentation resulting in a value of the strong coupling constant α s =0.165±0.01 (stat.). The independent fragmentation models, which yield values of α s between 0.10 and 0.15 depending on the treatment of energy and momentum conservation and of the gluon splitting, do not provide a satisfactory description of the data over the full angular range.
