One hundred and nine dogs were diagnosed as having been poisoned by viper (Vipera xanthina palestinae) venom between 1989 and 1996. Most of the cases occurred between April and September (86.2 per cent), with peaks in May (25.7 per cent) and July (20.2 per cent), and very few between November and February (3.6 per cent). Forty-two per cent of the dogs were poisoned in the evening (18.00 to 22.00), with a relative risk of 6.85, 17.4 per cent between 22.00 and 02.00, and 16.5 per cent between 14.00 and 18.00. The median age of the dogs was three years, and almost 80 per cent of them were from rural households. German shepherd dogs and rottweilers were over-represented (relative risk 1.98 and 1.87 respectively), and mongrel dogs and pinschers were under-represented (relative risk 0.41 and 0.53 respectively). Fifty-six per cent of the bites were on the head (excluding the mouth, lips and pinnae), 16.5 per cent on the front limbs, 9.7 per cent on the mouth and lips, 8 per cent on the hindlimbs, 4.4 per cent were submandibular and 5.4 per cent were at other sites. The main clinical signs were local swelling (98.2 per cent) and oedema (94.5 per cent), panting (45.7 per cent), tachypnoea (42.5 per cent), pain (34.9 per cent), tachycardia (29.8 per cent), lameness (25.7 per cent), and lymphadenomegaly (23.9 per cent). The mortality rate was 3.7 per cent. The most common haematological abnormalities were neutrophilia (67.6 per cent), leucocytosis (54.9 per cent), thrombocytopenia (51.9 per cent), increased haematocrit (47.6 per cent), and a left shift of neutrophils (37.8 per cent). Many biochemical abnormalities were observed, of which the most common were high activities of lactate dehydrogenase (84.6 per cent), creatine kinase (69 per cent), gamma-glutamyltransferase (40 per cent) and aspartate aminotransferase and high concentrations of globulin, phosphate and total bilirubin (33.3 per cent in each case).

The biomechanics of the hip joint provide an understanding of the development, evolution, and treatment of many disabling conditions of this joint. The available methods of biomechanical analysis include in vitro studies, in vivo studies, and theoretical mathematic analyses. The information obtained from these analyses have enabled the design of therapeutic programs to alleviate the symptoms of, and possibly delay the progression of, hip disease. The design of surgical procedures has been based on alterations of the biomechanics of the hip. These procedures have proven useful for treating pathologies such as osteoarthritis, hip dysplasia, and hip fractures. The study of biomechanics and biomaterials are integral to the current success of total hip arthroplasty in achieving pain relief and functional restoration.

Lameness is prevalent among broiler chickens and there is concern that it is chronically painful. The administration of an analgesic has been frequently used to identify pain in lame farm animals. Therefore, in this study the ability of lame and normal broiler chickens to traverse an obstacle course was tested after treatment with the analgesic, carprofen, a placebo saline injection or a control handling procedure. Sound birds traversed the course in approximately 11 seconds, irrespective of treatment. Lame birds took approximately 34 seconds to traverse the course, unless they received carprofen, which reduced their completion time to 18 seconds. Thus, carprofen substantially increased the speed of lame birds, providing evidence that birds with moderate lameness suffer pain when they walk.

Following injections of WGA-HRP into either the spinal cord or periaqueductal gray, labeled neurons were observed bilaterally along the periphery of the lateral reticular nucleus (LRN) magnocellular division. The possibility that some of these neurons in the LRN provide collateral axonal branches to both the periaqueductal gray and the spinal cord was investigated in rats using a retrograde double-labeling method employing two different fluorescent tracers, True Blue and Nuclear Yellow. Following sequential injection of the two fluorescent axonal tracers into the spinal cord and periaqueductal gray in the same animal, a modest number of double-labeled neurons were observed bilaterally near the medial and dorsal perimeter of the magnocellular division of the LRN. The labeled neurons were distinctly multipolar in shape and measured approximately 15-18 mu in their greatest transverse diameter. No double-labeled neurons were observed in the parvocellular or subtrigeminal divisions of the LRN. Based upon these observations, it is suggested that collaterals of the LRN-spinal pathway provide feedback information to the periaqueductal gray that might then be used to modulate the participation of the latter cell group in a variety of pain processing and cardiovascular regulatory functions.

In March 1996, a questionnaire was sent to 2000 veterinary surgeons, primarily involved in small animal practice, to assess their attitudes to perioperative analgesic therapy in dogs, cats and other small mammals. This paper is concerned only with the data relating to dogs. The veterinary surgeons considered that pain was a consequence of all the surgical procedures specified, but there were differences in their treatment of pain. Some veterinarians considered that a degree of pain was necessary postoperatively to prevent excessive activity. In general, women and more recent graduates assigned higher pain scores to the procedures and were more likely to treat the pain with analgesics. A significant number of veterinarians consider the use of opiates or non-steroidal anti-inflammatory drugs before surgical procedures, but relatively few appear to use combinations of different classes of analgesics either before or after operations.

The effects of factors such as the position of the tongs, the presence of wool, and the wetness of the skin on the efficiency of the head-only stunning procedure, and the duration of the periods of unconsciousness and analgesia were studied in lambs. The degree of insensibility was determined from the evaluation of physiological responses and electroencephalograms. The proportion of successfully stunned animals was significantly higher (P<0.05) in the animals stunned with the tongs in a frontal position than in those stunned with them in a caudal position, in the animals stunned with wet electrodes than in those stunned with dry electrodes and also in the animals without wool than in those with wool. The interval between stunning and sensibility to pain was affected significantly (P<0.01) only by the position of the tongs, being longer in animals with them in a frontal position than in those with them in a caudal position.

Eighty-nine cats and 38 dogs naturally infested with the ear mite Otodectes cynotis were randomly allocated into two treatment groups. One group was treated with a product containing miconazole nitrate, polymyxin B sulphate and prednisolone acetate, the other with a combination of diethanolamine fusidate, framycetin sulphate, nystatin and prednisolone. The treatment (five drops in each ear) was applied twice daily for 14 days, and its efficacy was evaluated on days 7, 14 and 21 on the basis of an otoscopic examination of the external ear canal, a microscopical examination of scrapings for the presence of ear mites and clinical signs of pruritus, pain, erythema and/or exudate. Both treatments were highly effective, and there were no significant differences between the two products, either in efficacy or in the clinical improvements observed. Apart from an allergic reaction in one cat treated with the second product, no adverse effects were observed.

Thirty bitches undergoing routine neutering were used in an assessor-blinded trial of the postoperative analgesic effects of pethidine and carprofen administered either together or singly. The level of analgesia was assessed by visual analogue scale (VAS) scores for pain and sedation and by nociceptive mechanical threshold testing. The two drugs administered together, and carprofen alone, provided good postoperative analgesia as assessed by VAS scoring. Pethidine alone did not provide postoperative analgesia of sufficient duration.

A composite scale for assessing pain in dogs in a hospital setting has been developed on the basis of observations of their behaviour. Initially, 279 words and expressions suggested by 69 veterinary surgeons were reduced into 47 words and expressions which were allocated into seven behaviour categories: demeanour and response to people, posture, mobility, activity, response to touch, attention to painful area and vocalisation. Three statistical methods, hierarchical agglomerative cluster analysis, Cronbach's alpha coefficient, and analysis of variance with multiple comparisons and empirical cumulative distributions, were used to validate these procedures, and a questionnaire accompanied by a list of definitions was designed around the expressions. The new composite scale is more detailed than previously reported scales for assessing pain in dogs on the basis of their behaviour, and the methods used in its development are based on sound scientific principles.

The existence of noradrenergic projections from the lateral reticular nucleus (LRt) to the dorsal quadrant of cervical, thoracic, or lumbar spinal cord was investigated using a combined method of WGA-apo-HRP-gold retrograde tracing and dopamine-beta-hydroxylase (DBH) immunocytochemistry. Preliminary retrograde tracing studies indicated that LRt neurons projecting to cervical, thoracic, or lumbar spinal cord were characteristically located near the perimeter of the LRt. Double-labeling experiments demonstrated that a portion of these peripherally-located, spinal-projecting neurons were DBH-immunoreactive. Double-labeled neurons were also located at the parvocellular division of the contralateral LRt in the thoracic injection cases. Double-labeled neurons were not observed at the subtrigeminal division in cervical, thoracic, or lumbar injection case. The results suggest the possibility that the noradrenergic LRt-spinal pathway might be involved in a variety of pain processing and cardiovascular regulatory functions in the rat.
