Abnormality in a fœtal calf

Hématome sous dural fœtal

L'hématome sous dural in utero (HSD) est très rare, se soldant fréquemment par le décès du fœtus. Le mécanisme de formation de ces hématomes n'est pas encore élucidé. Le premier cas a été rapporté en 1977 par Mc Donald et coll. Le diagnostic est posé le plus souvent par l'échographie. L'imagerie par résonance magnétique peut être réalisée si existe un doute diagnostique. L'hématome est le plus ...

Renal Hypoplasia in a Calf

Renal hypoplasia refers to a congenitally small kidney where there is essentially normal residual parenchyma but smaller calyces, lobules, and papillae. This anomaly can be divided into two broad groups: complete (global) renal hypoplasia and segmental renal hypoplasia. In this study, a 3 days-old simmental calf was diagnosed with renal hypoplasia and unreconstructed exstrophic bladder. It pres...

Myocardial epithelial inclusions in a Holstein calf

Epithelial inclusions were detected in myocardium of a 2-month-old male Holstein calf. Microscopically,nonpurulent myocarditis along with focal tubular and acinar structures covered with cuboidal epithelial cellswas seen in the myocardium. Most tubular and acinar structures stained with Masson’s trichrome were foundto be surrounded with a dense collagen. Tubular and acinar structures had PAS po...

Abnormality Detection in a Landing Operation Using Hidden Markov Model

The air transport industry is seeking to manage risks in air travels. Its main objective is to detect abnormal behaviors in various flight conditions. The current methods have some limitations and are based on studying the risks and measuring the effective parameters. These parameters do not remove the dependency of a flight process on the time and human decisions. In this paper, we used an HMM...
