Harrison B irds are curious pets and frequently investigate unusual textures, containers and locations throughout the home. Contact with or consumption of certain plants, cleaners, pesticides and household disinfectants may cause acute or chronic intoxication. Most compounds considered toxic to mammals should also be considered toxic to birds. Based on their size and physiology, birds are more prone than mammals to intoxication by some compounds, such as volatile chemicals and fumes. All avian clients should "bird-proof" their homes to provide a safe and enjoyable environment for their companion birds. It has been suggested that the consumption of foreign bodies (eg, metal, wood, jewelry), over-consumption of grit and coprophagy may all be mediated by malnutrition (Gerlach H, unpublished). Therefore, birds on a formulated diet would be expected to chew less on plants, perches and toys than birds on a seed-based diet. Treat seizures and shock as needed Caustic to skin and mucous membranes, Flush affected areas with water or milk. Treat for shock and pain burns in mouth, tongue, pharynx Abdominal pain, vomiting, bloody feces, rapid shallow respiration, chlorates may cause methemoglobinemia Crop or gastric lavage.

Do not give bicarbonate orally for acid poisonings Many of the therapeutic recommendations for the above products have been taken from small animal sources. Toxin-contaminated water, air and food supplies can affect birds through direct contact or through poisoning of components in the food chain. Often the intoxication is subtle, and poisons accumulate over time (eg, lead in waterfowl, organochlorines in birds of prey). Birds of prey and fish-eating birds are particularly susceptible to contaminants in the food chain because of biologic magnification. It is of interest that the health of free-ranging birds is frequently ignored as a sensitive indicator of human-induced damage to our environment. In this case, a conure was presented with lead poisoning secondary to the consumption of lead-containing solder used to hold his feeding dish. The case was further complicated by gastrointestinal impaction secondary to the ingestion of pieces of the plastic dish and malnutrition caused by a diet of wild bird seeds. Clinicians should carefully evaluate the environment in birds with clinical signs consistent with toxicity. In addition to human-related toxins, food and water supplies encountered by free-ranging birds may also be contaminated by biologic organisms that produce their own toxins, including molds (mycotoxins), bacteria (endotoxins) and certain blue-green algae (hepatotoxins). When submitting samples for toxicologic analysis, it is best to call the laboratory for information on proper sample preparation and shipment. Most laboratories request frozen samples (except whole blood), preferably individually wrapped to prevent crosscontamination.
Recovery from proventriculotomy is usually uneventful when the impaction is detected early symptoms you have diabetes buy generic pepcid on-line. Chronic impactions may be accompanied by gastric atony treatment modalities purchase pepcid 40mg without a prescription, ulcers and candidiasis that require additional therapy symptoms detached retina buy cheapest pepcid and pepcid. Birds can be offered alfalfa pellets and corn as soon as they are fully recovered from anesthesia treatment nurse generic pepcid 40 mg with visa. A proventriculotomy to remove the foreign body and surgical removal of necrotic peritoneum is indicated. Cloacal prolapse may be associated with diarrhea, or more frequently, with tenesmus due to constipation. Treatment of the prolapse is similar to methods used in other birds, but the initiating cause must be addressed to prevent recurrence (see Chapter 41). Intussusception is caused by hypermotility and gastrointestinal tract irritation and is often the result of an abrupt dietary change, especially when the new diet is higher in fiber. Cantharidin, for example, is a toxin produced by the Three-striped Beetle, which swarms to feed on Mesquite trees and alfalfa hay. Mortality levels of 25% were reported in a group of emus that consumed these beetles that were attracted to a barn light. The etiology is unknown, but it is speculated that an abrupt change in feed may be an inciting factor. Intestinal anastomosis may be effective in resolving mild cases that do not involve an extensive amount of the gastrointestinal tract. This porphyruria is routinely noted following the ingestion of fresh green vegetation, and becomes more prominent during colder weather when water intake reduction makes the urine more concentrated. Fractures Leg fractures are common in ratites, and successful repair is difficult in these large, fractious, easily stressed, bipedal birds that must be able to ambulate postoperatively. The long-term use of slings is unsuccessful with ostriches, but emus tolerate them well. Tibiotarsal fractures in small birds under 15 kg are best repaired with a through-and-through, six-pin, modified external fixation device (see Chapter 42). Fractures of the phalanges, fractures of the distal metaphysis of the tarsometatarsus and luxations of the metatarsal-phalangeal or interphalangeal joints can be stabilized with fiberglass casts, to which most ratites readily adapt. Overweight yearlings that are subjected to physical stress are most commonly affected. Degenerative Myopathy A large percentage of the young ostriches, rheas and emus submitted for necropsy have evidence of degenerative myopathy, with the majority of affected birds being less than six months of age. In birds, several etiologies for degenerative myopathy have been reported, including capture myopathy, selenium or vitamin E deficiency, furazolidone and ionophore toxicity. White foci and streaks in the myocardium and muscles of the hind limbs and myocyte degeneration with infiltration of macrophages and early calcification may be noted in birds that die several days after transport. Ionophore coccidiostats, such as monensin, lasalocid and salinomycin, are frequently added to chick starter feeds. These compounds may be contributing factors in the development of degenerative myopathy, and ratite producers should avoid the use of turkey or chick starter feeds that contain furazolidone and ionophores. In the southern United States, pastures may contain the shrubs or trees of coffee senna (Cassia occidentalis or Cassia obtusifolia). In ruminants, ingestion of these beans may cause diarrhea, weakness, gait abnormalities, recumbency and muscular lesions consistent with degenerative myopathy. Fractures of the leg are relatively easy to repair surgically, but are rarely successful long-term because of problems in managing these large, fractious, bipedal patients (courtesy of Louise Bauck). A small diameter pin may enter the distal caudal surface of the humeral shaft and be advanced through the fracture site into the proximal fragment. Alternatively, the pin may enter the proximal fragment at the fracture site, be advanced proximally out the deltoid crest and then retrograded into the distal fragment. The wing is then taped to the body for a period of six weeks to provide rotational stability to the fracture site.

Stage 2 (F2): Furcation 2 involvement exists when a periodontal probe extends greater than half way under the crown of a multirooted tooth with attachment loss but not through and through 4 medications at target buy generic pepcid 20mg line. The loss of periodontal attachment is less than 25% as measured either by probing of the clinical attachment level medicine xl3 buy genuine pepcid line, or radiographic determination of the distance of the alveolar margin from the cementoenamel junction relative to the length of the root treatment episode data set 40 mg pepcid overnight delivery. Plaque removal and control consists of 4 aspects depending on the level of disease. Extraction this section will cover the complete dental prophylaxis/cleaning as well as basic indications for periodontal surgery and extractions. Homecare and basic extraction techniques will be covered elsewhere in this document, however periodontal surgery is beyond the scope of these guidelines. Regardless of the name, the goal of this procedure is not only to clean and polish the teeth, but also to evaluate the periodontal tissues and entire oral cavity. Only when the patient is properly anaesthetized can a safe and effective cleaning and oral exam be performed. It is important to note that proper periodontal/dental/oral therapy takes time and patience. A minimum of one hour should be allotted for all dental cases and much more in many instances. Professional periodontal therapies must be performed with quality (not quantity) in mind. The physical exam, in combination with pre-operative testing, screens for general health issues which may exacerbate periodontal disease or compromise anaesthetic safety. The use of a periodontal diagnostic strip by the examining veterinarian can improve the accuracy of the conscious periodontal evaluation. The veterinarian can then discuss the various disease processes found on the examination as well as the available treatment options with the owner. This face-to-face discussion will improve client understanding of the disease processes and associated sequela. Based on the oral examination findings, the practitioner can create a more accurate estimate both of procedure time and financial costs to the client. The client should be made aware at this point that a complete oral examination is not possible on a conscious patient. Furthermore, they should not be performed near any sick or compromised patients, or near any clean procedures. This means that dental cleanings often result in a transient bacteremia, which is more severe in patients with periodontitis. The most common used mechanical scaler in veterinary dentistry today is the ultrasonic model. Both types of ultrasonic scalers are very efficient and provide the additional benefit of creating an antibacterial effect in the coolant spray (cavitation). At slower rates of vibration, they generate minimal heat, and therefore may be a safer alternative to ultrasonics (See equipment section for a complete discussion of mechanical scalers). Mechanical scaling When using any of the mechanical scalers, the first concern is the power level setting of the instrument. Ultrasonic tips have a recommended oscillation (Hz) range and this should be determined and set prior to initiating scaling. Next, it is important to ensure that there is adequate coolant being delivered through the working end of the scaler. Specific low-powered periodontal tips are available for subgingival use, and clinicians and staff should familiarize themselves with this equipment prior to their use. Units supplied with periodontal tips also have settings on the machine appropriate for subgingival scaling. The instrument should be gently grasped to increase tactile sensitivity, decrease operator fatigue and provide superior cleaning.
Species that infect psittacine birds include Ascaridia columbae (shared with pigeons) medications heart failure order pepcid 20 mg, A symptoms heart attack order cheap pepcid online. The eggs are resistant to disinfectants but can be controlled with steam or flaming treatment 6th feb cardiff buy pepcid australia. Mild infections can cause malabsorption symptoms zoloft overdose buy cheap pepcid line, weight loss, anorexia, growth abnormalities and diarrhea. Heavier parasite loads may cause intussusception, bowel occlusion or death (Figure 36. Providing a dry clean environment will decrease the possibility that eggs will survive to embryonate. Piperazine, pyrantel pamoate and fenbendazole may be effective in resolving infections. Cerebrospinal nematodiasis caused by larvae from Baylisascaris procyonis (raccoon ascarids) has been reported in gallinaceous birds, cockatiels, ratites and several Passeriformes. When they enter the central nervous system, the larvae induce considerable damage leading to ataxia, torticollis, depression and death. The earliest clinical signs developed 35 days after potential exposure to the raccoons. Necropsy findings included multifocal encephalomalacia of the brain stem and cerebellum caused by Baylisascaris larvae. The best means of control is to prevent access of free-ranging raccoons to aviaries, and thus prevent contamination of the environment by these thickwalled and long-lived eggs. The bird had lost most of its pectoral muscle mass (weight 230 g), and had a distended abdomen. Radiographs indicated enlarged bowel loops, diffusely filled with linear soft tissue densities. This bird was maintained in a mixed species outdoor exhibit with access to the ground. Intestinal nematodes are rare in companion birds maintained indoors and in aviary birds maintained in suspended enclosures. Ascarids in the genus Heterakis can infect the ceca of gallinaceous birds, Anseriformes and other birds. In some species (quail), infections are subclinical, while other affected birds can die from complications associated with the mucosal and submucosal lesions. Capillaria: Species of Capillaria are tiny thread-like nematodes that may infect the gastrointestinal tract of most species of companion and aviary birds. Severe infections can cause diarrhea (which may contain blood), weight loss, anorexia, vomiting and anemia. Species of this genus in other birds are profound pathogens when they reside in the upper digestive tract, particularly in gallinaceous birds. Eyelid spasms and mild conjunctival hyperemia were evident in a Senegal Parrot with Thelazia even though only three adults were recovered. The parasite has an indirect life cycle that involves an arthropod (cockroach) intermediate host. In severe infections, diaphoretic esophagitis or gastritis associated with ulceration and frank hemorrhage may occur. Spiroptera incerta and Dispharynx nasuta have been reported in association with thickening of the proventricular mucosa in a number of Psittaciformes (see Color 19). The adult worms burrow into the proventriculus causing ulcers, inflammation and nodule formation. The proliferative mucosa may prevent the passage of ingesta resulting in chronic vomiting and weight loss (Figure 36. A large-mouthed worm (Cyathostoma cacatua) related to gapeworms has been reported from the air sacs of a Sulphur-crested Cockatoo. Syngamus: Syngamus trachea (gapeworm) has been Embryonation requires approximately two weeks, and eggs can remain infectious in the environment for several months. The adults can burrow into the mucosa of the esophagus, crop or intestinal tract causing depression, dysphagia, regurgitation, diarrhea, melena and weight loss. Capillaria that infect the crop, esophagus and oral cavity burrow into the mucosa, creating tracts that may fill with blood, producing hyperemic streaks.
