Surgical management of cricopharyngeal dysphagia in dogs: 14 cases (1989-2001).

OBJECTIVE: To determine outcome of and complications associated with cricopharyngeal myotomy or myectomy for treatment of cricopharyngeal dysphagia (CPD) in dogs. DESIGN: Retrospective study. ANIMALS: 14 dogs. PROCEDURE: Medical records of dogs with CPD that underwent cricopharyngeal myotomy or myectomy were examined. Follow-up information was obtained through telephone interviews with owners and referring veterinarians and clinical examinations when feasible. RESULTS: 16 surgical procedures were performed on the 14 dogs. Dysphagia was completely resolved immediately after surgery in 1 dog, and clinical signs did not recur (follow-up time of 8 years); a second dog also had immediate complete resolution of dysphagia, but follow-up time was only 10 days. Three dogs had transient complete resolution with a mean time to recurrence of dysphagia of 12.3 weeks (range, 2 to 36 weeks). Three dogs had permanent partial resolution. Six dogs had no improvement after surgery. Eight of the 14 dogs were euthanatized because of problems related to CPD, including persistent dysphagia (n = 8) and aspiration pneumonia (5). CONCLUSIONS AND CLINICAL RELEVANCE: The failure rate for dogs undergoing surgical treatment of CPD may be high, particularly if concurrent aspiration pneumonia or malnutrition is not addressed prior to surgery. For those dogs with concurrent diseases, more aggressive medical management, such as enteral tube feeding, may be warranted rather than surgery. In dogs with CPD complicated by other anatomic or functional conditions, such as myasthenia gravis, laryngeal paralysis, and esophageal stricture, surgery may also not be indicated.

Evaluation of infertility in the bitch.

The majority of bitches that are brought to a veterinarian for reproductive evaluation are actually healthy. Infertility in the bitch is most commonly due to inappropriate breeding management rather than an inability to conceive. Before embarking on an exhaustive medical evaluation, it is important to obtain a thorough history and physical examination to identify any problems. Completion of a routine database assists in detecting significant systemic illness that may impact infertility. After consideration of history, physical examination, and minimum database, fertility problems are most commonly considered in one of four categories: abnormal estrous cycles, normal estrous cycles, failure to breed, or failure to carry a litter to term. This classification system aids in construction of a differential list and systematic evaluation of all differentials. The majority of diagnostic tests required are available to the general practitioner. Before any treatment for infertility, adequate health management must be ensured. Specific treatment for the most common causes of infertility is centered on appropriate breeding management.

Advanced small animal reproductive techniques.

Small animal reproductive techniques have become quite advanced in recent years. Techniques described in this paper include transcervical catheterization for the purpose of insemination and intrauterine diagnostics (e.g., cytology, culture, and/or biopsy), and semen cryopreservation that allows international shipping of valuable semen and preservation of reproductive capacity. The use of uterine and fetal monitoring devices that enable intervention and mediation of dystocia is also described.

2006 AAHA canine vaccine guidelines.

In 2005, AAHA's Canine Vaccine Task Force met to reexamine and revise guidelines on the use of vaccines in dogs. The results of the Task Force's work are summarized and tabulated in this article and are published in their entirety on the AAHA website (www.aahanet.org). The 2006 AAHA Canine Vaccine Guidelines contain information on new technological developments in vaccines, an introduction to conditionally licensed vaccines, and detailed recommendations on the use of available vaccines. Perhaps the most noteworthy addition to the guidelines is a separate set of recommendations created for shelter facilities. Vaccines are classified as core (universally recommended), noncore (optional), or not recommended. The Task Force recognizes that vaccination decisions must always be made on an individual basis, based on risk and lifestyle factors.

Report of the American Animal Hospital Association (AAHA) Canine Vaccine Task Force: executive summary and 2003 canine vaccine guidelines and recommendations.

The AAHA has undertaken the development of this document in an effort to inform veterinary practitioners, clarify misunderstandings held by veterinarians, and encourage practitioners to recognize that immunization of patients is a medical procedure. As such, it is bound by the same tenets that govern the recommendation of other medical procedures-principally, that it be tailored to the needs of the individual patient. Many diseases we immunize against are ubiquitous. Many are serious and some even life threatening. Some are of limited demographic concern given the exposure risk for each patient. These factors have all been considered in developing the AAHA Canine Vaccination Guidelines. In the end, each veterinarian must do what he or she determines to be in the best interest of the patient. Vaccination of individual animals produces not only individual immunity but also population or herd immunity. Since we have no readily available and reliable way to determine if each patient has developed an adequate immune response, we encourage the practice philosophy of vaccinating more patients while vaccinating each patient no more than needed.
