Abstract
The short-term effects of prednisone and phenobarbital on serum total thyroxine (tT4), free thyroxine (fT4), and thyroid stimulating hormone (TSH) were evaluated in euthyroid dogs. Twenty-six beagles were randomly divided into 3 groups receiving, respectively, a placebo, prednisone (1.2 to 2 mg/kg body weight, per os, every 12 hours for 3 weeks), or phenobarbital (1.8 to 3 mg/kg body weight for 1 week, then 2.7 to 4.5 mg/kg body weight, per os, every 12 hours for 2 weeks). Blood samples taken over a 6-week period were assayed for serum tT4, fT4, and TSH. Phenobarbital therapy in our study did not affect serum tT4, fT4, or TSH concentrations. Prednisone therapy, however, significantly decreased serum tT4 and fT4, but did not affect serum TSH concentrations.

Abstract
BACKGROUND Radiotherapy after mastectomy to treat early breast cancer has been known since the 1940s to reduce rates of local relapse. However, the routine use of postoperative radiotherapy began to decline in the 1980s because it failed to improve overall survival. We prospectively tested the efficacy of combining radiotherapy with chemotherapy. METHODS From 1978 through 1986, 318 premenopausal women with node-positive breast cancer were randomly assigned, after modified radical mastectomy, to receive chemotherapy plus radiotherapy or chemotherapy alone. Radiotherapy was given to the chest wall and locoregional lymph nodes between the fourth and fifth cycles of cyclophosphamide, methotrexate, and fluorouracil. RESULTS After 15 years of follow-up, the women assigned to chemotherapy plus radiotherapy had a 33 percent reduction in the rate of recurrence (relative risk, 0.67; 95 percent confidence interval, 0.50 to 0.90) and a 29 percent reduction in mortality from breast cancer (relative risk, 0.71; 95 percent confidence interval, 0.51 to 0.99), as compared with the women treated with chemotherapy alone. CONCLUSIONS Radiotherapy combined with chemotherapy after modified radical mastectomy decreases rates of locoregional and systemic relapse and reduces mortality from breast cancer.

Abstract
Serum free thyroxine (FT4) concentrations using chemiluminescence were measured in hyperthyroid cats (n = 72) and clinically normal cats (n = 129) to establish reference values and to determine if this method could be a useful alternative to total T4 (TT4) measurement by radioimmunoassay (RIA). Mean serum FT4 concentration (68.3 +/- 26.8 pmol/L) of hyperthyroid cats was significantly higher than that of euthyroid cats (22.9 +/- 4.8 pmol/L). Reference values for basal FT4 of hyperthyroid and healthy cats were 33 to 114 pmol/L and 16 to 30 pmol/L, respectively. The results of the present study suggest that FT4 measured by chemiluminescence could be a useful alternative to TT4 measured by RIA when evaluating thyroid function in cats, since the hazardous effects of radioactive materials on the manipulators and the environment could be avoided. Further studies are required to corroborate these preliminary findings.

Abstract
The purpose of this study was to determine the usefulness of free thyroxine (FT4) measured by chemiluminescence in evaluating thyroid function in dogs. Total thyroxine (TT4) concentration measured by radioimmunoassay (RIA) and FT4 measured by chemiluminescence were evaluated in 30 healthy dogs, 60 euthyroid dogs with concurrent dermatopathies, and 30 hypothyroid dogs before and after intravenous stimulation with 1 or 2 IU of thyrotropin (TSH). Median basal TT4 and median TT4 concentrations at 4 h post-TSH administration were not significantly different (P < 0.0001) between healthy dogs and euthyroid dogs with dermatopathies, but were significantly higher than those in hypothyroid dogs. In healthy dogs, the median TT4 concentrations at 4 and 6 h post-TSH administration were not significantly different. Median basal FT4 and median FT4 concentrations at 4 h post-TSH administration in healthy dogs were significantly lower (P < 0.0001) than those in euthyroid dogs with dermatopathies, but significantly higher than the same parameters in hypothyroid dogs. There was a significant difference between the median FT4 concentrations at 4 h post-TSH administration and median basal FT4 concentrations for healthy dogs and euthyroid dogs with dermatopathies, but not for hypothyroid dogs. Lastly, in healthy dogs, median FT4 concentrations at 4 and 6 h post-TSH administration were not significantly different. Free thyroxine measured by chemiluminescence was highly correlated (P < 0.0001; Spearman r = 0.91) with FT4 measured by the reference method for free hormone analysis, namely, equilibrium dialysis, when sera from 56 dogs were used.

Abstract
A randomized, placebo-controlled, double-blind, three-way crossover design was used to evaluate the effectiveness of single oral 100 mg doses of CI-988, a cholecystokinin B (CCKB) antagonist, in attenuating panic symptoms induced by intravenous injection of cholecystokinin-tetrapeptide (CCK-4). Thirty healthy men received the following treatments on three separate occasions: placebo capsules/placebo, placebo capsules/CCK-4, or CI-988 capsules/CCK-4. There was no marked difference in the number, time to onset, or duration of panic symptoms between CI-988/CCK-4 and placebo/CCK-4. There was, however, a 14% difference in sum intensity scores between these treatments that was statistically significant (p = 0.039). The symptoms most affected by CI-988 were cold chills/hot flushes, chest pain/discomfort, and anxiety/fear/apprehension. Panic attack frequency also decreased following CI-988 treatment (8/30 vs. 16/30; p = 0.035). This decrease, amid otherwise modest effects, could be explained by a preferential effect of CI-988 on the subjective experience of anxiety/fear/apprehension. Possible reasons for the relatively modest effects of CI-988 on CCK-4-induced panic symptoms are discussed.

Abstract
OBJECTIVE To evaluate the efficacy of daily administration of ivermectin in the treatment of dogs with amitraz-resistant generalized demodicosis. DESIGN Prospective, clinical trial. ANIMALS Twelve privately owned dogs with juvenile-onset or adult-onset generalized demodicosis that had failed to respond to biweekly or weekly applications of 0.025% amitraz solution. PROCEDURE All dogs were treated with undiluted ivermectin at a dosage of 0.6 mg/kg of body weight, PO, every 24 hours. There was no other parasiticidal agent given topically or systemically. A physical examination and multiple skin scrapings were performed every 2 to 4 weeks while dogs were receiving ivermectin. Skin scrapings were performed at approximately the same sites at every examination. After no mites were seen, treatment was continued for at least 2 more weeks and then stopped. Dogs were reexamined, and skin scrapings were repeated if any skin lesions developed. For dogs that remained clinically normal, follow-up information was obtained by telephone. Dogs that were free of clinical signs of demodicosis 12 months after ivermectin administration was discontinued were considered cured. RESULTS Ten of 12 dogs were cured. Median duration of treatment for these dogs was 10 weeks (range, 6 weeks to 5 months). Two dogs were failures, relapsing 10 months and 11.5 months after treatment was stopped. One of these dogs was successfully treated with a second course of ivermectin. Mild ivermectin toxicosis developed in 1 dog after 6 weeks of treatment; side effects resolved shortly after the treatment was stopped. CLINICAL IMPLICATIONS Daily use of ivermectin, at a dosage of 0.6 mg/kg, PO, was found to be effective in the treatment of generalized demodicosis in dogs.

Abstract
Wuillemin, Richardson, and Lynch (1994) claim to have determined that languages learned after the age of 8 are less lateralized than those learned earlier. The authors fail to specify the nature of what it is that is differentially lateralized. It cannot be implicit linguistic competence (the language system), since that has been clinically demonstrated to be false. It cannot be pragmatic and paralinguistic aspects of language use, since, to the extent that these are right-hemisphere based functions, they could not be reflected in results obtained with a technique assumed to selectively tap left-hemisphere functions. Either way, the visual half-field technique used proves to be an invalid measure of language laterality in individuals or subgroups.

Abstract
Thyroid function was evaluated in 18 healthy dogs by thyrotropin (TSH) stimulation. Two dose regimens were used in each dog: 0.1 IU/kg body weight of freshly reconstituted lyophilized TSH and 1 IU/dog of previously frozen and stored TSH (up to 200 days), both given intravenously. Blood samples were collected prior to and at four and six hours after TSH administration. Serum was evaluated for total thyroxine concentrations by radioimmunoassay. All dogs were classified as euthyroid on the basis of response to 0.1 IU/kg body weight of freshly reconstituted TSH at four and six hours. The 1 IU dose of TSH, previously frozen for up to 200 days, induced increases in serum total thyroxine concentration over baseline at four and six hours that were not significantly different from those resulting from the use of the higher dose of fresh TSH. In all test groups, there were no statistically significant differences between total thyroxine concentrations at four and six hours post-TSH administration. It was concluded that an adequate TSH response can be achieved with the use of 1 IU of TSH/dog for clinically normal dogs between 29.0 kg and 41.6 kg body weight, even if this TSH has been frozen at -20 degrees C for up to 200 days. Further, blood collection can be performed at any time between four and six hours. Similar studies are needed to evaluate this new protocol in hypothyroid dogs and euthyroid dogs suffering nonthyroidal systemic diseases.

Abstract
The neuropeptide cholecystokinin-tetrapeptide (CCK-4) has potent anxiogenic action in human and animal subjects. On the basis of prior work which demonstrated that benzodiazepine (BZD) receptor agonists antagonized CCK-induced excitation of rat hippocampal neurons we studied whether BZD receptors mediated the anxiogenic effect of CCK-4. To examine this possibility we determined whether the BZD receptor antagonist flumazenil could antagonize the effects of CCK-4 (50 micrograms) in healthy volunteers. Thirty subjects (10 females; 20 males) were pretreated with flumazenil (2 mg in saline) or placebo (0.9% NaCl in water) 15 min prior to CCK-4 challenge in a randomized double-blind crossover design. Flumazenil had no impact on the behavioral and cardiovascular effects of CCK-4, suggesting that BZD receptors do not mediate the anxiogenic action of CCK-4. The influence of GABA and non-GABA-related mechanisms on response to CCK-4 remains to be considered.

Abstract
An in-office allergy screening kit was evaluated in 10 dogs that had no clinical signs of atopy but had various intestinal parasites. All 10 dogs had a positive reaction to the dust mite Dermatophagoïdes farinae, and four dogs had positive reactions to at least one other group of allergens. The kit as presently marketed gives numerous false positive results in parasitized nonatopic dogs.

Abstract
Inherited Alzheimer's disease is a genetically heterogeneous disorder that involves gene defects on at least five chromosomal loci. Three of these loci have been found by genetic linkage studies to reside on chromosomes 21, 19, and 14. On chromosomes 21, the gene encoding the precursor protein of Alzheimer-associated amyloid (APP) has been shown to contain several mutations in exons 16 and 17 which account for roughly 2-3% of familial Alzheimer's disease (FAD). The other loci include what appears to be a susceptibility gene on chromosome 19 associated with late-onset (> 65 years) FAD, and a major early-onset FAD gene defect on the long arm of chromosome 14. In other early- and late-onset FAD kindreds, the gene defects involved do not appear to be linked to any of these three loci, indicating the existence of additional and as of yet unlocalized FAD genes. This review provides a historical perspective of the search for FAD gene defects and summarizes the progress made in world-wide attempts to isolate and characterize the genes responsible for this disorder.

Abstract
Records from two breeding colonies (A and B) located near each other were analyzed for this experiment. Colony A consisted of 19 bitches (8 Maltese, 5 Yorkshire, 3 Lhasa Apso, and 3 Bouvier des Flandres), while Colony B consisted of 48 Beagle bitches. A total of 126 interestrous intervals (141 estrous cycles) from Colony A were reviewed to quantitate the variability of the interestrous interval. Analysis of variance showed that the degree of variation of the estrous cycle length within bitches (65%) was about twice the degree of variation of means of the estrous cycle length among bitches (35%). It was found that the estrous cycle length is extremely variable, and it cannot be used to predict the next estrus in a single bitch, although some bitches were very consistent. The seasonal and monthly distribution of estrous cycles throughout the year was also analyzed from bitches kept in Colonies A and B for a total of 210 estrous cycles. The data were collected over a four-year period. A seasonal pattern was observed when the cumulative distributions over years were analyzed. A higher frequency of estrous cycles was observed during winter and summer. This seasonality pattern was not observed when individual years were analyzed separately. However, the overall probability that an estrus would occur at any month of the year was the same for each month (1/12) when cumulative distribution over years were analyzed.

Abstract
Dermatological disorders accounted for 18.8% and 15.2%, respectively, of all the dogs and cats examined at the Small Animal Clinic, University of Montreal, Saint-Hyacinthe, during a one-year period. In dogs, the most common groups of dermatological disorders encountered were bacterial folliculitis and furunculosis, allergic dermatitis, endocrinopathy, neoplasia, ectoparasitism, and immune-mediated dermatitis. The most common primary final diagnoses were bacterial folliculitis and furunculosis, atopy, food hypersensitivity, flea bite hypersensitivity, hyperadrenocorticism, and hypothyroidism. Breed predispositions were found for several canine dermatoses: bacterial folliculitis and furunculosis (collie, German shepherd, golden retriever, Newfoundland), atopy (boxer, golden retriever), food hypersensitivity (boxer, German shepherd), hyperadrenocorticism (miniature poodle), hypothyroidism (Doberman pinscher, Gordon setter), castration-responsive alopecia (chow chow), demodicosis (Old English sheepdog), and idiopathic pruritus (pit bull terrier).In cats, the most common dermatoses were abscesses, otodectic mange, cheyletiellosis, flea bite hypersensitivity, atopy, flea infestation, neoplasia, and food hypersensitivity. Himalayan and Persian cats accounted for 50% of the cases of cheyletiellosis and 75% of the cases of dermatophytosis, respectively. Hereditary primary seborrhea oleosa was seen only in Persian cats.

Abstract
Sterile nodular panniculitis was diagnosed in 5 horses. Physical abnormalities were predominantly limited to cutaneous changes, consisting of multiple subcutaneous nodules that had a tendency to wax and wane over time and were commonly distributed over the trunk, neck, and proximal portion of the limbs. In each horse, the diagnosis was confirmed by excisional biopsy of a nodule and by exclusion of infective causes of panniculitis on the basis of negative culture results and special stain application to skin specimens. Treatment with immunosuppressive doses of glucocorticoids was curative in 1 horse, was required on a daily or alternate-day schedule in 2 others to keep the skin clear, and had no effect on the disease in the remaining 2 horses.

Three black giant schnauzers, mother, daughter and son, developed single or multiple primary squamous cell carcinomas of the nail bed between the ages of nine and 12 years. The clinicopathological findings are described. Radiographic evidence of osteolysis of the third phalanx, especially in a middle-aged to older large-breed, black dog would warrant the amputation and histopathological examination of the digit because of the likelihood of squamous cell carcinomas.

Abstract
A case of alopecia areata (pelade) is described in a cow. Alopecia areata is a rare idiopathic dermatosis of cattle. It is characterized by asymptomatic, solitary or multiple, annular areas of noninflammatory alopecia. Scrapings and cultures are negative, and the diagnosis is confirmed by skin biopsies taken from early lesions, which reveal accumulations of lymphocytes around the bulbs of anagen hair follicles. There is no known effective and practical treatment for affected cattle. The dermatitis is a cosmetic problem, but does not seem to affect general health and production, and spontaneous remission may occur.

Abstract
Twenty adult dogs (11 Cocker spaniels and 9 miniature Poodles) with naturally occurring cheyletiellosis were treated twice, at a three-week interval, with subcutaneous injections of ivermectin at the dose rate of 300 mug/kg. Ivermectin proved to be very effective against Cheyletiella yasguri infestation in dogs. All treated animals were completely cured after one or two treatments. No adverse reactions were noted. Ivermectin should be avoided in Collies and Collie crosses.
