Abstract:

El presente estudio tuvo como objetivo identificar y describir las características macroscópicas y microscópicas de la anatomía del páncreas de la alpaca, tanto en fetos del último tercio de gestación como en neonatos (0-30 días). Se estudiaron los páncreas de tres fetos del último tercio de gestación, y de crías de alpaca recién nacidas (n=3), de 0 días (n=5), 7 días (n=5), 15 días (n=5) y 30 días (n=5). En el estudio macroscópico se observó el páncreas in situ, sus conductos y su relación con otros órganos, tomándose medidas biométricas (longitud corporal, altura a la cruz, perímetro torácico y perímetro abdominal) y el peso de los individuos. Macroscópicamente, el páncreas es similar al de las alpacas adultas. Microscópicamente, el páncreas presenta una citoarquitectura celular definida, formada por acinos tubulares de citoplasma acidófilo, elongado, de núcleos basales e islotes irregulares (en cuanto a tamaño y forma), además de grupos celulares no diferenciados. Esta citoarquitectura varía en la primera semana de edad, donde la conformación de los acinos e islotes es irregular, presentando una alta tasa de división celular y gran cantidad de células precursoras distribuidas por todo el campo. La actividad celular disminuye con la edad, encontrándose en los animales de 30 días de nacidas una citoarquitectura bastante similar al de las alpacas adultas.

Abstract:

La crianza de las alpacas (Vicugna pacos) en el Perú, constituye uno de los mayores recursos para la sobrevivencia y seguridad alimentaria de los pobladores altoandinos. La anatomía digestiva de la alpaca aún no está descrita completamente para explicar los procesos fisiológicos y nutricionales. Con el objetivo de describir la estructura del estómago fetal de la alpaca, se utilizaron seis fetos de alpacas Huacaya obtenidos del matadero, distribuyéndose dos fetos (macho y hembra) para cada tercio de gestación. Se realizó la disección de los fetos exponiendo los estómagos, se efectuaron las medidas del largo y ancho de los tres compartimentos (C), además se describieron los surcos y celdillas del C1. Se realizó el análisis de varianza considerando el efecto sexo, edad gestacional, C y sus interacciones, cuya variable de respuesta fue el largo y ancho de los C del estómago. No hubo interacción (P>0,05) para ninguna de las variables de estudio. El largo y ancho de los tres C del estómago fetal fueron similares en machos y hembras (P>0,05). El largo y ancho de los C fueron menores (P≤0,05) en primer tercio de gestación, aumentando las medidas en segundo y último tercio de la gestación. El largo del C3 fue mayor (P≤0,05) que el C1 y C2, mientras el ancho del C1 fue mayor (P≤0,05) que el C2 y C3. En el C1 del saco dorsal, hubo más surcos perpendiculares y celdillas en el último tercio de la gestación. En conclusión, los tamaños de los C del estómago fetal de la alpaca aumentaron conforme avanzó la edad gestacional. Además, en el C1, hubo más surcos perpendiculares y celdillas en el último tercio de la gestación.

Abstract:

Abstract Case Description—3 alpaca crias and cadavers of an alpaca cria and a llama cria were evaluated for evidence of esophageal dysfunction. Clinical Findings—All 5 crias were between 3 and 5 months of age when clinical signs developed, and all had a thin body condition when examined. Clinical signs included coughing, regurgitation, and grossly visible esophageal peristaltic waves. A barium esophagram was used to diagnose esophageal obstruction, megaesophagus, and a vascular ring anomaly (VRA). Fluoroscopy was used to evaluate deglutition, esophageal peristalsis, and the extent of esophageal dilation in 1 alpaca cria. A persistent right aortic arch was identified in 1 alpaca cria, and a left aortic arch with right ductus arteriosus or ligamentum arteriosum and an aberrant right subclavian artery were identified in the 4 remaining crias. Treatment and Outcome—Surgical correction of the VRA was attempted in the 3 live alpaca crias. It was complicated by the conformation and location of each VRA and inaccurate anatomic diagnosis of the VRAs before surgery. Treatment was universally unsuccessful because of intraoperative complications and the persistence of clinical signs after surgery. Clinical Relevance—Megaesophagus is typically an idiopathic condition in camelids. However, these findings suggested that camelids with esophageal dysfunction during the neonatal period may have a VRA. The prognosis is grave for camelids with VRA, and accurate anatomic diagnosis of the VRA via the use of advanced imaging techniques (eg, angiography, computed tomography, or magnetic resonance imaging) may improve the success of surgical intervention.

Abstract:

Abstract Background Scientific knowledge regarding alpaca dentistry is relatively limited despite its clinical implications. The present gap in available supportive data leads to limited treatment options for dental pathology in alpacas in comparison to other species. The main goal of this study was to gain novel insights into the general and pulp morphology of maxillary cheek teeth to allow development of more advanced treatment strategies in the future. Also, the risk of causing pulp exposure when floating maxillary cheek teeth was of particular interest. Concurent research focusing on the anatomy of mandibular cheek teeth has been performed accordingly. The results obtained in mandibular teeth are expected to be non-extrapolatable because of the structural differences between mandibular and maxillary teeth. Results Pulp morphology of maxillary cheek teeth showed great variation. A common pulp chamber was identified in 46/83 (55.4%) teeth with a mean dental age of 2 years and 7 months (± 2 years and 5 months). Pulpal segmentation was more commonly observed in teeth of increasing age. Full columnar segmentation was seen in 33/69 teeth (47.8%), whereas within-column segmentation was observed in 36/83 teeth (43.4%). Age and degree of segmentation of the pulpal tissue varied greatly according to Triadan position. Physical contact between roots of adjacent teeth was found in the majority of examined molars (range 82–94%) which resulted in morphological adaptations at the level of the root tips. The measured sub-occlusal dentinal thickness was as low as 0.46 mm above pulp horn 2 in a 14 years and 11 months old Triadan 09, emphasizing the risk of pulp exposure attributed to dental floating. Conclusion This study offers an objective description of age-dependent maxillary cheek teeth pulp morphology in alpacas. Current findings are of great value to provide a basis for the development of tooth-saving techniques as a treatment for dental disease in this species. Observed physical contact between the roots of different examined molars may be a facilitating factor in the spread of apical infection in chronically diseased cases. Finally, a conservative approach regarding dental floating is recommended in order to avoid iatrogenic damage to pulp tissue.

Abstract:

Abstract Background Despite dental disease being a common health concern in alpacas, important dental pathology including apical infection, remains poorly understood. Treatment options are limited compared to veterinary dentistry techniques in other species. The primary goal of this study was to increase understanding of the external and internal anatomy of mandibular cheek teeth to enable the development of tooth sparing techniques in this species. Also, an objective evaluation of the sub-occlusal dentinal thickness in normal mandibular cheek teeth is warranted to understand the risks associated with reduction of overgrown teeth. Results Overall pulp anatomy was variably characterized by the presence of a common pulp chamber in younger teeth, and segmentation of pulp cavities into multiple separate pulp entities within the same tooth with increasing age. A common pulp chamber was identified in 55.3% (26/47) of teeth with a mean dental age of 1 year and 11 months (± 1 year and 8 months). Columnar segmentation was recorded in the remaining teeth with a mean dental age of 6 years and 5 months (± 3 years and 11 months). Age of segmentation of the common pulp chamber into multiple separate pulp entities shows wide variation and is dependent of the specific Triadan position. The present study illustrates the presence of disto-mesial root contacts between adjacent tooth roots, often leading to morphological adaptations, most frequently observed between Triadan 09–10s (80%) and 10–11s (67%). The measured sub-occlusal dentinal thickness was as low as 1.11 mm over some pulp horns. The sub-occlusal dentinal thickness was lower than 2, 3, and 4 mm in 13.1, 38.1 and 61.4% of performed measurements, respectively. Conclusion This study provides detailed information on age-dependent mandibular cheek teeth anatomy in alpacas, which may support the use and development of advanced dental treatments in this species such as endodontics and tooth sectioning techniques. Apical morphological adaptations caused by disto-mesial root contact between adjacent mandibular cheek teeth are clearly illustrated. The limited amount of sub-occlusal secondary dentin warrants a cautious approach with regards to dental floating in alpacas.
