    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.

    New results one + e −→μ + μ − from the JADE detector at PETRA (1985)

    Notes: Abstract The production of collinear muon pairs has been studied using the JADE detector at thee + e − storage ring at PETRA. Results for the total cross section and the angular distribution were obtained at centre of mass (cm) energies ranging from 12 to 46 GeV. The data correspond to an integrated luminosity offLdt〉90 pb−1, of which 71.2 pb−1 were taken at $$\left\langle {\sqrt s } \right\rangle $$ =34.4 GeV and 17 pb−1 at $$\left\langle {\sqrt s } \right\rangle $$ =42.4 GeV. The results are compared to electroweak theories, in particular the “Standard Model”.

    Electroretinogram as a possible monitor of anesthetic depth (1986)

    Notes: Abstract The effects of volatile anesthetics, i.e., methoxyflurane, halothane and enflurane, on the electroretinogram (ERG) were studied in 15 albino rabbits. The ERG was analyzed in terms of the a-wave, and the first oscillatory component (01) in the b-wave. The 01 peak latency showed a significant dose-related prolongation when anesthetic end-tidal concentrations were in excess of 0.8 minimum alveolar concentration (MAC). One MAC, a measure of anesthetic potency, is the end-tidal concentration of an anesthetic at 1 atmosphere that induces immobility in 50% of animals against a noxious stimulus. The amplitudes of the a-wave and the 01 decreased in dose-dependent manners, but their changes were less striking than those of the 01 latency. The peak latency of the a-wave remained unchanged. We conclude that the 01 peak latency is a useful monitor of the depth of inhalational anesthesia.
