Asteroid hyalosis in the dog

Two cases of asteroid hyalosis in the dog are described. Asteroid hyalosis is a rare degenerative phenomenon in the vitreous body. Ophthalmoscopically it is characterized by spherical, small bodies which gleam brilliantly in the vitreous like stars in the night sky. Histochemically these spherical bodies are a calcium-lipid complex. The etiology of asteroid hyalosis is unknown. The condition usually does not give rise to symptoms and can not be influenced by conservative treatment.     

Replacement of the hip joint in the dog

Hundreds of total hip replacements in dogs have been performed at the Ohio State University of Veterinary Medicine since August 1976. Dogs with disabling diseases or conditions of the hip are candidates for the THR. The technique provides the dog with a pain free, mechanically sound ball and socket joint. The most commonly encountered complication is dislocation, while the most disastrous complication is infection. Complications can be minimized through adherence to detail during the procedure. By following strict aseptic principles, surgical technique and postoperative care, successful hip function has been achieved in 94.7% of the cases.     

Indocyanine green test in the dog

The ICG test is recommended as a replacement for the nowadays rarely performed BSP test. ICG has less side effects, and it has a greater range of use. Extrahepatic influences are of little importance. Disadvantages are the greater cost and extra equipment required, the labile nature of the dye solution and the calculation procedure. Reference ("normal") values of the clearance coefficient are 0.044 to 0.131 min-1 and those for the half life 5.2 to 11.2 min. The test is suitable for information about the secretion of the whole liver and the state of its circulation.     

Ossifying parotid tumor in the dog

Diagnosis and treatment of an ossificated parotis-neoplasma is demonstrated. The etiology is unknown.     

Fluid therapy in the dog and the cat

Underlying principle for fluid therapy is the knowledge about distribution of body water (60% of body weight) into compartments: intra- and extracellular fluid (ICF, ECF) cover respectively one half, one sixth of the latter fills the intravascular system. According to the concentration of ions and molecules in the lost fluids, dehydration is classified into hypertone, hypotone and isotone. Clinical assessment and laboratory examination (PCV, hemoglobin, total protein, urine analysis, electrolyte and blood gas evaluation) are crucial features for determination of dehydration rate, acid-base and electrolyte imbalances. Derangements of body-fluid and electrolyte metabolism and their treatment are discussed. The quantity of fluids necessary for rehydration of the patient is calculated on the basis of clinical findings. Overhydration risk has to be considered more seriously in cats than dogs. Intravenous, subcutaneous, oral and intraperitoneal infusions are feasible. A survey to technical aspects and required instruments is presented in conclusion.     

The clinical picture of multiple enchondromatosis in the dog

The clinical and radiological findings of three related Miniature Poodles with multiple enchondromatosis (Ollier's disease) are presented. Persisting, in part ossified growth plate cartilage foci were found bilaterally in the humerus, radius, ulna, femur, tibia and fibula of each dog and in one dog in some metacarpal and metatarsal bones. The ribs and many vertebral bodies were also affected. There was evidently no bone formation in the sternebrae. All three dogs first attracted attention at the ages of four to six months, with spontaneous bilateral femoral neck fractures. The mode of inheritance of the condition is not yet clear, but based on the known pedigree data a dominant effect appears unlikely.
