Revisión sistemática de las diferentes técnicas quirúrgicas de contracepción en gatas

In the veterinary clinic, contraceptive surgery is the most commonly performed surgery in female cats. However, it is not established which surgical technique is the most appropriate. In order to reduce postoperative pain, recovery time, surgery time and technical ease for the surgeon, different surgical techniques and variations of these techniques have been described. This has created the dilemma of performing ovariohysterectomy versus oophorectomy; type of approach: midline, lateral or laparoscopic; and method of ovarian pedicle ligation: harmonic scalpel, plastic and titanium clips, bipolar electrocautery, pedicle knot and traditional ligation. With this in mind, with the objective of establishing which is the most adequate contraceptive surgery in female cats and supported by evidence-based medicine, a systematic review was carried out. Using Google Scholar, Web of Science, PubMed and Scielo search engines, with the following variables to be evaluated: pain, time and technical difficulty. It was found that there is little evidence to establish the superiority of any surgical technique over another and that the choice of surgical technique should be made based on the patient, the surgeon's skills and the availability of materialsEn la clínica veterinaria, la cirugía contraceptiva es la más practicada en gatas. Sin embargo, no está establecido cuál técnica quirúrgica es la más adecuada. Con la finalidad disminuir el dolor posoperatorio, tiempo de recuperación, tiempo de cirugía y facilidad técnica para el cirujano, se han descrito diferentes técnicas quirúrgicas y variaciones de las mismas. Esto ha creado el dilema sobre la realización de ovariohisterectomía contra la ovariectomía; tipo de abordaje: línea media, lateral o laparoscópico; y método de ligadura del pedículo ovárico: bisturí harmónico, clips de plástico y titanio, electrocauterio bipolar, nudo pedicular y ligadura tradicional. Teniendo esto en cuenta, con el objetivo de establecer cuál es la cirugía contraceptiva más adecuada en gatas y apoyados en la medicina basada en evidencias, se realizó una revisión sistemática. Utilizando los buscadores Google Académico, Web of Science, PubMed y Scielo, con las siguientes variables a evaluar: dolor, tiempo y dificultad técnica. Se encontró que existe poca evidencia para establecer la superioridad de alguna técnica quirúrgica sobre otra y que la elección de la técnica quirúrgica debe de ser realizada en base al paciente, habilidades del cirujano y la disponibilidad de materiale

Gastroesophageal reflux in anesthetized dogs: a review

Gastroesophageal reflux can be a catastrophic illness in small animals during anesthesia since its complications can cause serious pathologies, such as esophagitis, esophageal stenosis and aspiration pneumonia. With an incidence from 12 to 78.5% in anesthetized dogs, gastroesophageal reflux is normally silent during anesthesia and will be notices only if regurgitation occurs and stomach acid is present in the nasal or oral cavities. In humans, gastroesophageal reflux disease (GERD) is a well-defined pathology where the lower esophageal sphincter has a sustained weakness. However, in dogs, gastroesophageal reflux disease as such is not well established, if at all; it has only been described as gastroesophagic reflux, occurring principally in anesthetized animals. There are several factors influencing the presentation of reflux in anesthetized dogs, which may be inherent to the patient (e.g. age, sex, breed, weight, or body condition), medications used prior to and during anesthesia, type of surgery or position of the animal during surgery. The objective of this review is to discuss a series of conditions that could predispose dogs to gastroesophageal reflux during anesthesia and to assist in the prevention and diagnosis of this condition.O refluxo gastroesofágico durante a anestesia pode ser uma entidade catastrófica na clínica de pequenas espécies, já que suas complicações resultam em entidades realmente graves, como esofagite, estenose esofágica e pneumonia por aspiração. O refluxo gastroesofágico em cães anestesiados é geralmente silencioso, com uma incidência de 12 até 78.5% e só é observada quando há regurgitação e o refluxo passa até a cavidade oral ou nasal. Nos humanos, a doença pelo refluxo gastroesofágico (ERGE) é uma patologia bem definida, onde o esfíncter esofágico inferior apresenta uma debilidade continua. Porém, esta doença em cães não está bem estabelecida, pelo qual só se descreve o refluxo gastroesofágico, que ocorre principalmente em animais anestesiados. Existem diversos fatores que influenciam na apresentação do refluxo em cães anestesiados. Estes podem ser inerentes ao paciente (por exemplo: idade, sexo, raça, peso ou condição corporal), a medicamentos utilizados previamente e durante a anestesia, ao tipo de cirurgia ou a posição do animal durante a cirurgia. O objetivo da revisão foi discutir uma guia das condições que predispõem à aparição de refluxo gastroesofágico durante a anestesia em cães com o fim de facilitar o diagnóstico e a prevenção dessa condição.El reflujo gastroesofágico durante la anestesia puede ser una entidad catastrófica en la clínica de pequeñas especies, ya que sus complicaciones derivan en entidades realmente graves como esofagitis, estenosis esofágica y neumonía por aspiración.

Chronic Expanding Hematoma Secondary to Excision of Recurrent Myxomas in a Bitch

Background: Expanding chronic hematoma is a relatively common postoperative complication in humans, not in dogs, nevertheless, is important understand this condition because it may affect the animal’s health. A hematoma could be formed within hours and usually stabilizes spontaneously with the reabsorption of its content. However, occasionally the hematoma slowly expands, becomes encapsulated and forms a mass, causing a chronic expanding hematoma. Possibly skin and adipose tissue are displaced secondary to trauma, causing the formation of blood-filled cysts surrounded by a fibrous capsule. The aim of this document is to present the first report of a postsurgical chronic expanding hematoma in dog. Case: A case of chronic expanding hematoma secondary to excision of recurrent myxoma in a bitch was described. Physi-cal examination showed a hard, firm, non-mobile mass enclosed within the deep muscular layers. This mass was between the sternum and the cranial abdomen, similar to previous lesions excised by another veterinarian. Fine needle aspiration indicated the presence of blood. Radiology demonstrated that the bone-cartilage tissue was not involved. Due to the size of the mass, a skin stretching pre-suturing technique using self-adhesive tape was applied around the mass 48 h before surgery. The mass was removed with wide excision margins and portions of the affected muscles, but a large wound with great tension was created; consequently, a parallel to the wound incision and the thoraco-lumbar vertebrae was made. Six months after surgery, the animal presented recurrence of the same lesion, which was also

Possible Association between Selected Tick-Borne Pathogen Prevalence and Rhipicephalus sanguineus sensu lato Infestation in Dogs from Juarez City (Chihuahua), Northwest Mexico–US Border

Tick-borne bacterial pathogens (TBBPs) show a worldwide distribution and represent a great impact on public health. The brown dog tick (Rhipicephalus sanguineus) is a vector of several pathogens that affect dogs and sometimes humans as well. In addition, TBBPs represent a diagnostic challenge and imply financial resources and medical treatment for long periods of time. In the present study, R. sanguineus s. l. was identified as the main tick species naturally parasitizing dogs that inhabit. Juárez City, Chihuahua, in the Paso del Norte region, Mexico–US Border, representing 99.8% of the cases. Additionally, an end-point PCR was performed to search for whether pathogens in R. sanguineus s. l. can transmit in DNA extracted from ticks and dog blood samples. This is the first molecular detection of Rickettsia rickettsi infecting domestic dogs in Mexico; however, other pathogens were also identified, such as Ehrlichia canis and Anaplasma platys in both ticks and dog blood samples, while Anaplasma phagocytophilum was identified only in dog blood samples. Moreover, co-detection in tick pools and co-infection in the analyzed dog blood samples could be found. Similarly, this research showed that dogs were found mostly parasitized by adult female ticks, increasing the possibility of transmission of E. canis
