Opis:: In [1] the authors proved that a semiring S is a completely simple semiring if and only if S is isomorphic to a Rees matrix semiring over a skew-ring R with sandwich matrix P and index sets I and Λ which are bands under multiplication. In this paper we characterize all the balanced order relations on completely simple semirings. Also we study the normal hull of a completely simple semiring.

Opis:: The statistical estimation problem of the normal distribution function and of the density at a point is considered. The traditional unbiased estimators are shown to have Bayes nature and admissibility of related generalized Bayes procedures is proved. Also inadmissibility of the unbiased density estimator is demonstrated.

Opis:: Background: The purpose of this study was to determine the normal diameters of larger airways in the Persian population, since these demographic variables are essential for interpretation of chest CTs and/or plain X-rays. Material/Methods: During a 6-month period, sagittal and coronal diameters of tracheas of all cases admitted for a chest CT to the radiology department of the National Research Institute of Tuberculosis and Lung Disease (NRITLD) were measured. The patients had to accept to take part in the study and had to fulfill the inclusion and exclusion criteria of the study. Ninety-nine percent confidence intervals (99% CI) were used to define the upper and lower limits of normal. Results: Two hundred subjects, including 132 men and 68 women aged 20-85 years, were studied. Coronal and sagittal diameters of tracheas in the upper part were as follows: 1.8±0.24 and 2.06±0.27cm for men, and 1.48±0.20 and 1.49±0.24 for women, respectively. For the lower part that was: 1.8±0.23, 1.86±0.27, 1.51±0.18, and 1.46±0.23, respectively. For the right and left mainstem bronchi the values were as follows: 1.16±0.17 and 1.02±0.22 for men and 0.93±0.13 and 0.81±0.13 for women, respectively. Conclusions: The values determined by us had a narrower range of normality than the ones found in the previous reports, so they will stay more friendly for interpretation of individual cases.

Tytuł:: Computed tomography evaluation of variations in positions and measurements of appendix in patients with non-appendicular symptoms : time to revise the diagnostic criteria for appendicitis
Autorzy:: Kumar Singh, Deepak
Singh, Neha

Agrawal, Gaurav Raj
Opis:: Purpose: To estimate the frequency distribution of different anatomical positions, and to measure the diameter, wall thickness, and length of appendix in patients with non-appendicular symptoms. Material and methods: This retrospective observational study was conducted among 1,575 patients, who had undergone computed tomography (CT) scan of abdomen for various non-appendicular signs and symptoms. Frequency of distribution of different anatomic locations and measurements of various morphologic parameters were recorded. Results: The most common location of appendix was retrocecal, followed by sub-cecal, post-ileal, and pelvic locations. The mean length of appendix was 66.7 mm (range, 6.3-123 mm), and the diameter was 6.3 mm (range, 2.8-11.3 mm). Diameter of > 6 mm was noted in 48.12% patients. The mean wall thickness was 2.37 mm, ranging 1.2-4.2 mm. The most common intra-luminal content was air-mixed with hypodense or hyperdense material observed in 70.5% of cases. Conclusions: Although an appendix with diameter less than 6 mm may be considered normal, a diameter above 6 mm has an overlap between a normal and inflamed appendix. Therefore, it should be considered in association with clinical and secondary findings to avoid overdiagnosis and unnecessary appendicectomies. We strongly recommend that diameter-based CT criteria to diagnose appendicitis should be revised and standardized.
