Incidence and Pattern of Pneumonia in Goats Slaughtered at the Kumasi Abattoir, Ghana

This study aimed at determining the incidence and pattern of pneumonia, in slaughtered goats in Kumasi abattoir, Ghana. One thousand three hundred and fifty lungs of goats; (1,012 Sahelian and 338 West Africa Dwarf goats (WAD) lungs) of different ages (less than a year to above 4 years) were used in this study. The frequency of occurrence of pneumonia, the degree of consolidation as a percentage of the total lung volume and histological assessment were determined by standard techniques. Fifty five (55) lungs (39 Sahelian, 16 WAD goats) were pneumonic (4.07% prevalence). The right lungs had a significant higher average lung consolidation percentage (19.11) while the right cranial lobes were more affected (9.37). WAD goats of 1-2 years are mostly affected with an average percentage consolidation of 11.73% while Sahelian goats above 4 years of age were the most affected with 32.59% consolidation. Does of both breeds were more while Sahelian goats had higher consolidation than other breeds. Histological examination revealed the presence of giant cell, fibrinous and suppurative bronchointerstitial pneumonia suggesting complicated viral pneumonia which was observed to be the most important caprine pneumonia in slaughtered goats in Ghana. Transportation and pregnancy stress were the major contributory factor to the pneumonia observed hence effective ante-mortem examinations will help to minimize the slaughter of pregnant does and transportation stress in Ghana.

Incidence and classification of bifid mandibular canals using cone beam computed tomography

Aim: To determine the prevalence and classification of bifid mandibular canals using cone beam computed tomography (CBCT). Methods: The sample comprised 300 CBCT scans obtained from the Radiology and Imaging Department database at São Leopoldo Mandic Dental School, Campinas, SP, Brazil. All images were performed on Classic I-Cat® CBCT scanner, with standardized voxel at 0.25 mm and 13 cm FOV (field of view). From an axial slice (0.25 mm) a guiding plane was drawn along the alveolar ridge in order to obtain a cross-section. Results: Among 300 patients, 188 (62.7%) were female and 112 (37.3%) were male, aged between 13 to 87 years. Changes in the mandibular canal were observed in 90 patients, 30.0% of the sample, 51 women (56.7%) and 39 men (43.3%). Regarding affected sides, 32.2% were on the right and 24.5% on the left, with 43.3% bilateral cases. Conclusions: According to the results obtained in this study, a prevalence of 30% of bifid mandibular canals was found, with the most prevalent types classified as B (mesial direction) and bilateral.
