Symphyseal distraction-osteotomy using a novel spacer of spirally fashioned orthopaedic wire for the management of obstipation

Three domestic shorthair cats, one male and two females, 17.6+/-6.5 months old and 3.5+/-0.4 kg body weight, were admitted with a 6.6+/-1.1 (range 6-8) month history of recurrent bouts of obstipation. Defecatory difficulties had started within a month of conservatively managed pelvic fractures. Clinical and radiographic examination revealed severe colonic distension with faeces and a narrow pelvic canal caused by malunion of the pelvic fractures. A pelvic symphyseal distraction-osteotomy (SDO) technique was performed, using a novel metal spacer of spirally fashioned orthopaedic wire. Pelvic canal enlargement allowed the insertion of an index finger into the rectum. Following this, no further episodes of obstipation occurred during a follow-up period of 1-3 years. The SDO technique may be successful for the treatment of obstipation secondary to post-traumatic pelvic canal stenosis in the cat, if the colon motility is not already permanently affected.     

Clinical and epidemiological findings during ram examination in 47 flocks in southern Greece

In a field investigation of 47 flocks in south Greece, a clinical examination for fertility evaluation was done on 293 rams. In each ram, a general-health examination, examination of the genital organs and libido evaluation were carried out. In 143 (49%) of the 293 rams examined, at least one abnormality was recorded. The median within-flock prevalence risk (PR) of at least one abnormality was 58.0%, that of general-health abnormalities was 33%, that of genital abnormalities was 20% and that of libido abnormalities 14%. The principal abnormalities observed during the general-health examination were interdigital dermatitis, injuries of the sole, blowfly myiasis and brisket sores. The principal abnormalities observed during the examination of the genitalia were testicular hypoplasia, nodules into the testicular parenchyma, ulcerative lesions characteristic of orf in the prepuce and blowfly myiasis on the preputial orifice. The principal abnormalities observed during the evaluation of libido were incomplete erection and inability to mount the ewe. A statistically significant (P<0.05) positive association was recorded between: ram:ewe ratio and general-health abnormalities PR; general-health abnormalities PR and at least one abnormality PR; genital abnormalities PR and libido abnormalities PR; genital abnormalities PR and at least one abnormality PR; lambing percentage and total lambs born per ewe. A statistically significant (P<0.05) negative association was recorded between: ram age and general-health abnormalities PR; ram age and any abnormality PR; general-health abnormalities PR and lambing percentage.     

Effect of intrafragmentary bupivacaine (haematoma block) on analgesic requirements in dogs undergoing fracture repair

Objective

To test the efficacy of intraoperative intrafragmentary administration of bupivacaine (haematoma block) in controlling postoperative pain in dogs undergoing osteosynthesis of long-bone isolated diaphyseal fractures.

Canine bronchomalacia: a clinicopathological study of 18 cases diagnosed by endoscopy

Canine bronchomalacia (BM) is characterized by weakness leading to collapse of the bronchial wall. A prospective study of 18 affected dogs (age range: 1-15 years) was undertaken to characterize the clinicopathological and histological features of BM. Poodles and Yorkshire terriers were commonly affected. Half of the dogs were overweight or obese. The clinical presentation was a mild, wheezing, chronic cough and pulmonary crackles were heard in 28% of the dogs. Compatible radiographic changes were present in 61% of the dogs. Using bronchoscopy, both lungs were affected in half of the animals, whereas in the others the disease appeared to affect predominantly the left lung. Analysis of bronchoalveolar lavage fluid and biopsies of bronchial mucosa revealed pure or mixed neutrophilic inflammation. Underlying infectious bronchitis was considered possible in 56% of the dogs. It was concluded that canine BM may present as an isolated clinical entity associated with infection and/or inflammation.     

Fruit Production and Nutrient Status in Grapefruit on Five Rootstocks

A trial was conducted during two years (2000/01 and 2001/02) on two sites using ‘Shambar’ grapefruit trees grafted to five rootstocks. The sites were located on the Greek island of Kos to evaluate the effect of rootstock and location on fruit production and leaf mineral composition of ‘Shambar’ grapefruit. Results indicated that yields were higher in 2001/02 than in 2000/01 and these differences were greater at site 2. Leaf nitrogen (N), potassium (K), zinc (Zn), and to some degree phosphorus (P) content was slightly deficient to deficient for the majority of the samples taken. Calcium (Ca) and magnesium (Mg) levels ranged from normal to high. The copper (Cu) and iron (Fe) leaf contents and the manganese (Mn) content of most samples were in the optimum range. The interactions between rootstock, site, and year upon yield and nutrient content were statistically significant. There were also significant correlation coefficients between yield and nutrient content as well as among the nutrients.     

Benign esophageal stricture in the dog and cat: A retrospective study of 20 cases

Twenty animals with benign esophageal strictures are presented. Most of the esophageal strictures were thought to be related to gastroesophageal reflux during ovariohysterectomy and were located at the distal portion of the thoracic esophagus (caudal to the base of the heart). For the dilation procedure, the endoscope tip or a balloon catheter was used and the outcome was generally considered to be good. The endoscope tip was an adequate instrument for dilation in some cases.     

A comparison of propofol, thiopental or ketamine as induction agents in goats

OBJECTIVE: To compare propofol, thiopental and ketamine as induction agents before halothane anaesthesia in goats. STUDY DESIGN: Prospective, randomized cross-over study. Animals Seven healthy adult female goats with mean (+/-SD; range) body mass of 38.9 +/- 3.29 kg; 35-45 kg. METHODS: The seven animals were used on 21 occasions. Each received all three anaesthetics in a randomized cross-over design, with an interval of at least 2 weeks before re-use. Anaesthesia was induced with intravenous (IV) propofol (3 mg kg(-1)), thiopental (8 mg kg(-1), IV) or ketamine (10 mg kg(-1), IV). Following tracheal intubation, anaesthesia was maintained with halothane for 30 minutes. Indirect blood pressure, heart rate, respiratory rate and arterial blood gases were monitored. The quality of induction and recovery, recovery times and incidence of side-effects were recorded. RESULTS: Induction of anaesthesia was smooth and uneventful, and tracheal intubation was easily performed in all but two goats receiving ketamine. Changes in cardiopulmonary variables and acid-base status were similar with all three induction agents and were within clinically acceptable limits. Mean recovery times (time to recovery of swallowing reflex and to standing) were significantly shorter, and side-effects, e.g. apnoea, regurgitation, hypersalivation and tympany, were less common in goats receiving propofol, compared with the other treatments. CONCLUSIONS AND CLINICAL RELEVANCE: Propofol 3 mg kg(-1) IV is superior to thiopental and ketamine as an induction agent before halothane anaesthesia in goats. It provides uneventful recovery which is more rapid than thiopental or ketamine, so reduces anaesthetic risk.     

Effects of sarcoptic mange on the reproductive performance of ewes and transmission of Sarcoptes scabiei to newborn lambs

In each of two experiments, the reproductive performance of ewes naturally infested with sarcoptic mange and of uninfested ewes was assessed in in-season natural breeding conditions (experiment I) or in out-of-season controlled breeding conditions (experiment II). A statistically significant difference was observed in the total lambs born per ewe (infested ewes, 1.2; controls, 1.6), in the liveborn lambs per ewe (infested ewes, 1.2; controls, 1.5) and in the lamb body weight per ewe (infested ewes, 3.33kg; controls, 4.53kg) under natural breeding conditions, as well as in the lamb body weight per ewe (infested ewes, 3.37kg; controls, 4.14kg) among ewes under controlled breeding conditions. No adverse effects were observed in the other reproductive indices, cycling rate, mating rate, return-to-oestrus rate, abortion rate, lambing rate and stillbirth rate. Sarcoptic mange was observed in the offspring of infested ewes after 30 days and in the offspring of uninfested controls 60 days after their birth.     

Effect of Soil Plowing and Fertilization on the Susceptibility of Four Olive Cultivars to the Insect<Emphasis Type="Italic">Bactrocera oleae</Emphasis> and the Fungi<Emphasis Type="Italic">Sphaeropsis dalmatica</Emphasis> and<Emphasis Type="Italic">Spilocaea oleagina</Emphasis>

Susceptibility to the insectBactrocera oleae and the fungiSpilocaea oleagina andSphaeropsis dalmatica was investigated in four olive cultivars, two for table fruit production (Kalamon and Chondrolia Chalkidikis) and two for oil production (Lianolia and Koroneiki). Cv. Chondrolia Chalkidikis was the most susceptible to all three pathogens, followed by cv. Kalamon. Soil plowing and the organic fertilizer Bio-Trust^® (10-3-6+8% MgCO₃+10% CaCO₈) increased the susceptibility of all four tested olive cultivars to the insect and the two fungi. Correlations were found between the attacks byB. oleae and infections byS. oleagina andS. dalmatica on the four olive cultivars.
