Abstract: In 14 healthy male subjects we studied the effects of rib cage and abdominal strapping on lung volumes, airway resistance (Raw), and total respiratory resistance (Rrs) and reactance (Xrs). Rib cage, as well as abdominal, strapping caused a significant decrease in vital capacity (respectively, -36 and -34%), total lung capacity (TLC) (-31 and -27%), functional residual capacity (FRC) (-28 and -28%), and expiratory reserve volume (-40 and -48%) and an increase in specific airway conductance (+24 and +30%) and in maximal expiratory flow at 50% of control TLC (+47 and +42%). The decrease of residual volume (RV) was significant (-12%) with rib cage strapping only. Abdominal strapping resulted in a minor overall increase in Rrs, whereas rib cage strapping produced a more marked increase at low frequencies; thus a frequency dependence of Rrs was induced. A similar pattern, but with lower absolute values, of Rrs was obtained by thoracic strapping when the subject was breathing at control FRC. Xrs was decreased, especially at low frequencies, with abdominal strapping and even more with thoracic strapping; thus the resonant frequency of the respiratory system was shifted toward higher frequencies. Partitioning Rrs and Xrs into resistance and reactance of lungs and chest wall demonstrated that the different effects of chest wall and abdominal strapping on Rrs and Xrs reflect changes mainly of chest wall mechanics.

Abstract: This article describes the circumstances of the diagnosis of three of a group of 12 high-functioning multiple personality disorder patients. All had performed major social and professional activities with consistent competence, and all appeared to be neurotic patients suitable for classical psychoanalysis. All 12 had been misdiagnosed on at least three occasions before the correct diagnosis was made. Aspects of the difficulties encountered in assessing these patients are discussed and guidelines for the preservation of their high level of function during the treatment process are offered.

Abstract: Serum total sialic acid (TSA) and lipid-associated sialic acid (LASA) levels have drawn considerable interest because of carbohydrate aberrations in malignant cells. The current investigation determined the TSA, LASA, total protein (TP), and TSA/TP values for 171 cancer patients with various primary sites and differing degrees of metastatic disease, 102 patients with nonmalignant diseases (pathologic controls), and 42 normal individuals. Data analysis indicated significant (p less than 0.01) increases in the mean (+/- SD) TSA and TSA/TP values in the cancer patients (78.1 +/- 19.2 mg/dl and 12.4 +/- 3.8 mg/g, respectively) and in the pathologic controls (76.0 +/- 7.5 mg/dl and 11.6 +/- 2.5 mg/g) when compared to the normal controls (67.3 +/- 7.1 mg/dl and 9.0 +/- 1.1 mg/g), and a significant decrease in the mean TP values in the cancer patients (6.4 +/- 1.1 g/dl) and pathologic controls (6.6 +/- 1.1 g/dl) when compared to normal controls (7.5 +/- 0.5 g/dl). No significant difference was observed between groups in LASA values. Further analysis of the data in patient subgroups based on the tissue involved, specific disease, or severity of the malignancy indicated that the lack of specificity of the markers was due primarily to restricted subgroups and that the sensitivity of TSA and TSA/TP increased as the malignancy became more severe. The results show that TSA/TP was the most useful of the markers tested for detecting malignancies. This marker should prove useful for monitoring malignant disease recurrence and/or progression and for evaluating the effectiveness of various therapeutic approaches.
