Examination of a horse presenting with an acute nervous syndrome is often the only tool available to the practitioner before instituting treatment. This examination, which is often difficult to perform because of the state of the horse, is completed in three stages. Firstly a general clinical examination is performed to confirm the nervous cause of the symptoms and evaluate for possible state of shock. Secondly, examination of the cranial nerves will confirm or invalidate a central cause. Lastly, the precise location of the lesion may be obtained by peripheral nervous system examination, including tendon reflexes and flexion tests. Examination of the recumbent horse, whether lateral or sternal, is difficult because there is limited accessibility to parts of the horse.

A careful examination of the horse for which a cerebrospinal fluid puncture by lumbosacral route is required, gives the choice of the way of contention and degree of sedation. The correct positioning of the horse and the right locating of the site of puncture are required to realize this relatively easy act but sometimes dangerous with unpredictable reactions of the horse when the spinal needle penetrates the subarachnoid space. An adequate contention and a safe technique avoid blood contamination of the sample. If the technique is relatively easy, cerebrospinal fluid analyses are delicate and specific, in particular cytology that must be performed quickly.

After macroscopic examination of the cerebrospinal fluid, it must be quickly submitted to cytological analyses (counting and cellular differentiation). Cytology often gives a diagnostic orientation that is corroborated by biochemical dosages: proteins (albumin and IgG), glucose, enzymes (CK, AST, LDH) and lactates. Albumin quotient and IgG Index are determined with blood analyses. Indeed, according to the clinical exam and previous analyses, the cerebrospinal fluid can be submitted to immunological analyses, molecular biology, in particular for the diagnostic of viral troubles.

New data on the epidemiology and pathophysiology of equine gastric ulcer syndrome (EGUS) are presented in order to propose a targeted therapeutic approach and a more rational use of currently available drugs. Although preventive and therapeutic strategies for foals and adult horses may differ because of different risk factors, the same drugs are used to decrease gastric acidity regardless of the age of the patient. Prevention and therapy of gastric ulcers need to be targeted with respect to the principal risk factors that will determine when, with what and for how long therapy should be initiated. A better management of risk factors is also the first step in any preventive or therapeutic strategy. Hence, ration, training and non-steroidal anti-inflammatory drug use need to be considered.

Drugs used to treat gastric ulcers exert their action by either protecting the mucosa or reducing gastric acidity. Various mucosal protectants have had mitigated results while sucralfate appears to be indicated only for ulcers of the glandular portion of the stomach. Several therapeutic agents have been studied in order to assess their anti-acid efficacy in horses. The ability to reduce gastric acid secretion as well as the clinical efficacy for healing gastric ulcers varies considerably between drug classes. Histamine type 2 receptor antagonistes such as cimetidine, ranitidine and famotidine as well as proton pump inhibitors such as omeprazole are the only efficacious drugs to reach therapeutic objectives targeted for horses of all ages.

Spinal cord compression (myelopathy) in the cervical spine is the most common cause of ataxia in horses. Cervical stenotic myelopathy, induced by acquired vertebral malformation in the growing animal, is most often implicated. Yet other etiologies, either congenital, traumatic or acquired, have been described. Clinical and neurological examination provides confirmation of proprioceptive deficits (ataxia) and allows the localisation of lesions to the cervical region. However, a lesional diagnosis may only be obtained through imaging techniques. Radiography can provide significant data but confirming cord compression is rarely possible without performing myelography. The latter usually allows to localize the site, or sites, of compression and is therefore necessary whenever surgical treatment is considered. Unfortunately, traps and inaccuracies have been identified and should be taken into account in the interpretation of

A nine-year-old Shetland filly was presented for consultation for urinary incontinence. Sphincter incompetence was suspected after preliminary examination but genital endoscopy revealed discharge of urine into the vagina from an orifice distinct from the urinary meatus. A definitive diagnosis of left ectopic ureter was established using intravenous urography. In addition right renal agenesis was highly suspected. Ectopic ureter is a uni- or bi-lateral congenital malformation. In general, incontinence is seen from birth. Intravenous urography is the method of choice for diagnosis of ectopic ureters in foals and ponies. Administration of non ionic, tri-iodinated, low osmolarity contrast media similar to that used for dogs and cats is the technique engenders the least side-effects.

Although the distal sesamoidian ligaments (DSL) are found in the pastern area, functionally they are part of the suspensory system of the fetlock, in particular the oblique sesamoidian ligaments (OSL), which are a distal continuation of branches of the common digital extensor tendon. Ultrasonography is the ancillary examination of choice for assessment of tendinous or ligamentous conditions affecting the pastern. Ultrasonography of the DSL is easy but requires precise knowledge of the topography of the ligaments. This method of diagnostic imagery is non-invasive and easily accessible in general practice. Therefore ultrasonography should be an element of routine evaluation of conditions affecting the pastern, the metacarpo(tarso)phalangeal joints, and the suspensory system of the fetlock. This article describes the technique for ultrasonographical examination of the distal sesamoidian ligaments, presents reference ultrasonographical images, and indicates the main lesions seen in clinical cases.
