PURPOSE: If significantly influenced by chronic otomastoiditis(COM), mastoid pneumatization and the position of the sigmoid sinus affect the operative procedure and postoperative complications in middle ear surgery. We evaluated mastoid pneumatization and sigmoid sinus position, and their relationship in COM, especially its during onset. MATERIALS AND METHODS: Using temporal bone CT and referring to any relevant medical records, we retrospect+tively analyzed 107 cases of COM and 49 cases of normal ear. The total case load comprised an adult group, aged above 16 years [100 cases of COM (M:F=46:54, mean age = 45 years), and 42 cases of normal ear,(M:F=20:22, mean age = 44 years)], and a childhood group, aged less than 16 years [7 cases of COM (M:F=4:3, mean age = 8.4 years), and 7 cases of normal ear (M:F=4:3, mean age = 7 years)]. We determined the thickness of the mastoid bone by measuring the shortest distance between the outer cortex of this bone and the deepest border of the sigmoid sinus; the depth of the sigmoid sinus; and the degree of mastoid pneumatization and sclerosis. Fifty-three patients whose medical history clearly included the onset of otomas-toiditis were divided into a child-onset group and an adult-onset group, and the relationship between the onset of otomastoiditis and the thickness of the mastoid bone was compared between the two groups. RESULTS: The mean axial thickness of the mastoid bone was 9.672 <+/-2.745 mm in COM and 12.430 +/-3.027 mm in normal ear. The difference was statisfically significant (p < 0.0001). The mean depth of the sigmoid sinus was 7.557 +/-1.868 mm in COM and 7.591 +/-2.315 mm in normal ear, with no statistically significant difference. In the childhood group, the mean axial thickness of the mastoid bone was 8.672 +/-2.978 mm in COM and 11.778 +/-3.087 mm in normal ear. This difference was statistically significant (p < 0.05). In the adult group, the corresponding figures were 9.742 +/-2.731 mm in COM and 12.538 +/-3.041 mm in normal ear, a dif-ference which was also statistically significant (p < 0.0001). Among patients with an obvious history of COM, child-onset cases totalled 24 (mean axial thickness of the mastoid bone, 9.2.0 +/-2.158 mm), while there were 29 adult-onset cases (mean axial thickness, 10.08 +/-2.99 mm). This difference in thickness between child-onset and adult-onset COM was statistically significant (p < 0.05). CONCLUSION: In COM, the degree of mastoid pneumatization is proportional to the axial thickness of the mastoid bone, and inversely proportional to the degree of sclerosis, anterior location of the sigmoid sinus and the onset of COM. If the sigmoid sinus is properly located, COM may inhibit mastoid pneumatization.

Pulmonary involvement is more common in systemic lupus erythematosus (SLE) than in any other connective tissue disease, and more than half of patients with SLE suffer from respiratory dysfunction during the course of their illness. Although sepsis and renal disease are the most common causes of death in SLE, lung disease is the predominant manifestation and is an indicator of overall prognosis. Respiratory disease may be due to direct involvement of the lung or as a secondary consequence of the effect of the disease on other organ systems.

The content of meconium in amniotic fluid(AF) is important for assessing the risk of several perinatal problems such as asphyxia, meconium aspiration syndrome and various perinatal infections. This estimate is usually performed subjectively by visual inspection. The purpose of this study is to develop the objective method for quantitative measurement of meconium content in AF. Absorption spectra and meconium-crit of the solutions with various concentrations of meconium were measured. EfFects of filtration and blood contamination on the measurement of meconium content were also estimated by the same methods. Optical densities(OD) were correlated with concentrations of meconium in the whole range of scanned wavelengths. A specific peak of meconium was not available but the highest OD around 410 nm was shown. OD were linearly related to the concentrations of meconium. Meconium-crits were also well-correlated with the concentrations of meconium. Filtration of AF as well as blood contamination in AF severely affected the measurement of meconium content in AF. From the results of this study, both the spectrophotometric method and meconium-crit couid be objective methods for measuring meconium content. Both methods had merits and shortcomings. Filtration and blood contamination should be avoided for the measurement of meconium content in AF. We hope that both or either one of the two methods will be clinically used.

Oral contraceptives cause a number of serious side effects in young woman. Prominent among these is an increased incidence of thromboembolic events. Although these thromboemboli almost invariably occur on the venous side of the circulation, there have been reports describing the occurrence of arterial thromboses. Spontaneous thrombosis of the renal artery is a rare event. When reported, it has usually superimposed on an underlying anatomic abnormality of the renal artery after trauma, or very rarely in the setting of systemic disease such as polycythemia vera or thromboangiitis obliterans. Since isolated renal artery thrombosis in the absence of these underlying conditions has been rarely described, wewish to bring attention to the diagnosis of this disorder in a young woman taking oral contraceptives and without any other predisposing abnormality.

BACKGROUND: In Korea, a screening panel of cells from abroad without Di(a) positive cells has been commonly used when a patient has an unexpected antibody screening test. It has been reported that Di(a) occurs with a frequency of 6.14 to 14.5% among Koreans. However, the current popular antibody screening panels contain no Di(a) positive cells. In this study, we evaluate the clinical usefulness of the Di(a) Cell Panel (Diagnostic Grifols, Barcelona, Spain) for Koreans. METHODS: A total of 3,372 pretransfusion samples were employed for unexpected antibody screening testing using panels of cells by the DG Gel microtube column agglutination system, including additional Di(a) cells (Diagnostic Grifols, Barcelona, Spain). The positive cases in this system were confirmed again with DiaMed Di(a) antigen positive panel cells (DiaMed Ag, Cresssier, Morat, Switzerland) and this was followed by sequence- based Diego genotyping. RESULTS: The positive detection rate of an unexpected antibody screening test using SeraScan Diana I and II was 1.07% (36/3372), and seven samples were reactive (1+~2+) with the SeraScan Di(a) panel cells (0.21%). However, among the 5 available genotyped samples, two cases were typed as Di(a-b+). CONCLUSION: Even though there is discrepancy between the genotype and the two antibody screening kits, the addition of Di(a) positive cells as unexpected antibody screening panel cells is recommended.
