These selfprotective properties are anticipated to increase with age and training (Bramlage et al. Race distances and speeds are similarly distributed in relation to age and gender. Maximal carpal extension has also been shown to increase linearly with speed and gradient (Burn et al. No other population of flat racing horses in the literature presents such a high proportion of distal radius lesions or such a low prevalence of Cr involvement. It has been suggested that the medial aspect of the carpus may be more susceptible to injury as it is less protected by overlying muscle and tendon, undergoes greater loading (Bramlage et al. Standardbreds race at trot or pace, pulling a sulky rather than carrying a jockey. This reduces vertical loading forces through the forelimb, displaces the centre of gravity caudally and reduces loading of the carpus in the stance phase (Lucas et al. In the current study, 42/57 (74%) of multiple sites of carpal fragmentation were symmetrically paired. Of the total population, sites of fragmentation were identified in 165 (57%) left and 126 (43%) right limbs. Geographical limb bias has also been demonstrated within Australia where there is a difference between territories in sidedness of affected limbs according to racing direction (Raidal and Wright 1996). A weakness of this study was that 45% of the total number of horses undergoing surgery did not have both limbs evaluated arthroscopically. Identification of all limbs affected and total number of sites of fragmentation may therefore be underestimated. However, all horses underwent bilateral radiographic examination and all joints with radiographically identifiable sites of fragmentation were evaluated arthroscopically. Of horses which underwent bilateral arthroscopy, 58% had fragmentation identified in one limb only.

New therapeutic strategies under investigation may further enhance results and reduce the development of complicating factors. Introduction the uveal tract is the vascular tissue in the eye, consisting of the iris, ciliary body and choroid. Inflammation of these structures is termed uveitis and is the most common cause worldwide of equine blindness (Schwink 1992; Gilger and Deeg 2011; Hollingsworth 2011). Causes of primary, acute uveitis include local and systemic infectious diseases, blunt or penetrating trauma, neoplasia and idiopathic or immunemediated inflammation. Initiating or persisting infection alone does not sufficiently explain the clinical course or therapeutic response and recurrent episodes appear to result from epitope spreading (Deeg et al. The primary uveitis cause, environmental influences and genetic make-up of the individual play a role in the development of this immune-mediated disease (Gilger and Deeg 2011). No gender predilection has been proven, but 2 recent retrospective studies documented a significant overrepresentation of male horses (Kulbrock et al. The age of onset is variable, yet many cases present during mid-adult prime performance years (Dwyer et al. Initial ocular signs such as intermittent squinting, tearing, or cloudiness may be noted by owners weeks, months, or years prior to eventual presentation due to persistent signs of ocular pain, a change in appearance to the eyes, or vision compromise. Differences are presumed to be due to genetic and environmental factors (Deeg et al. It is characterised by episodes of persistent or recurrent intraocular inflammation that typically develop months after an initial uveitis episode subsides. The active stage involves acute flare-ups of uveitis showing observable pain and blood-ocular barrier breakdown as evidenced by blepharospasm, epiphora, photophobia, corneal oedema, keratic precipitates, aqueous flare, hypopyon, iris hyperaemia, miosis, hypotony, vitreal cellular infiltrate and/or retinal inflammation and detachment (Fig 1). The quiescent stage occurs after an active flare-up resolves and may last for weeks, months or greater than a year. During this period, eyes appear comfortable and have no evidence of active uveitis. Indicators of previous inflammatory episodes such as posterior synechia, pigment rests on the anterior lens capsule. End-stage eyes are irreversibly blind and may manifest with phthisis bulbi, pupillary seclusion, blinding cataracts, luxated lenses and/or retinal detachments (Figs 37 and Supplementary Item 1). It involves active observable inflammatory episodes followed by quiet periods, as described above and can occur in any horse. Detailed veterinary examination is necessary to identify the subtle signs of this smouldering inflammation which may go unnoticed by owners until cataract, vision deficits or endstage disease are present. Examination and clinical aids Ophthalmic examination should begin by assessing general eyelid and globe position, retroillumination, pupil size and symmetry, direct and consensual pupillary light reflexes and menace responses. If the menace response is not present a dazzle reflex can be performed in a dim light setting using a bright light source. Intraocular pressure should ideally be documented with an applanation or rebound tonometer (Fig 8). Sedation and periocular nerve blocks are used for examination of painful or uncooperative horses. A mild degree of aqueous flare is also present that contributes to the generally hazy appearance of the eye. Reflections are present on the corneal surface that are artifactual and not associated with ocular disease. The eye has a diffusely hyperpigmented iris, extensive posterior synechia and a complete cataract. Fig 6: Fundic image showing the optic nerve on the left side of the picture with radiating white folds indicative of retinal detachment. The eye was irreversibly blind but remained comfortable with medical management of the uveitis. The left eye had complete lens opacification, corpora nigra degeneration, lateral posterior synechia and diffuse iris hyperpigmentation. Pupils should be dilated with tropicamide to allow for complete lens, vitreal and fundic examination.

Pathology: Segmental demyelination with remyelination (onion bulb formation) and sparse mononuclear inflammatory change treatment 02 academy cheap 500 mg baycip. Despite little evidence medicine 606 cheap baycip express, immunosuppressive drugs (azathioprine symptoms bowel obstruction buy 500mg baycip amex, cyclophosphamide or cyclosporin) are deployed in resistant cases. Damage results from either metabolic disturbance with sorbitol and fructose accumulation in axons and Schwann cells or an occlusion of the nutrient vessels supplying nerves (vasa vasorum). The frequent occurrence of neuropathy with other vascular complications retinopathy and nephropathy suggests that the latter is the more usual mechanism. Neurological complications correlate with levels of glycosylated haemoglobin A1C, an indicator of the long-term control of hyperglycaemia. Two forms of sensory neuropathy occur large fibre, causing ataxia and small fibre causing a painful anaesthesia. Autonomic neuropathy In most patients with peripheral neuropathy, some degree of autonomic disturbance is present. Occasionally this predominates: pupil abnormalities loss of sweating orthostatic hypotension resting tachycardia gastroparesis and diarrhoea hypotonic dilated bladder impotence. The anterior thigh is preferentially affected with wasting of the quadriceps, loss of the knee jerk and minimal sensory loss. Cranial nerve palsy An oculomotor palsy, usually without pain, may occur with pupillary sparing, which helps to differentiate from an aneurysmal cause. Carbamazepine, gabapentin, pregabalin, tricyclic antidepressants or -adrenergic blockers. Drugs which reduce aldose reductase and halt accumulation of sorbitol and fructose in nerves are being evaluated. Asymmetrical neuropathies usually spontaneously recover, whereas prognosis for symmetric neuropathies is less certain. The neuropathy is characterised by the presence of antibodies (anti Hu) that are detected in serum. Such antibodies not only recognise antigen in tumours but also bind to peripheral nervous system neurons. Pathology the sensory type is characterised by degeneration and inflammatory changes in the dorsal root ganglion. In the sensorimotor type, degeneration of the dorsal root ganglion is less marked and axonal and demyelinative changes affect motor and sensory fibres equally. Clinical features Symptoms and signs may predate the appearance of causal malignant disease by months or even years. Sensorimotor neuropathy: the onset is gradual with distal sensory loss and mild motor weakness. Occasionally a more acute, severe neuropathy resembling Guillain-Barrй syndrome occurs. Detection and treatment of the underlying malignancy may lead to recovery of the neuropathy. Neuropathies may be axonal, demyelinating or mixed and show a variable response to immunotherapy. An increased production of porphobilinogen is reflected by its increased urinary excretion. Clinical features the onset is acute and predominantly motor with upper limb and occasional cranial nerve involvement. Autonomic involvement with tachycardia, blood pressure changes, abdominal pain and vomiting often develop. During an attack, a high carbohydrate diet and prevention and treatment of electrolyte disturbances are essential. Neurophysiology Motor conduction velocities slowed < 38 m/sec in common peroneal nerve. Autosomal recessive point mutation chromosome 1 or 17 or sporadic Many complex forms of hereditary neuropathies occur and the above classification is far from complete with the genetic basis for many now determined. Some pedigrees show additional features such as optic atrophy, retinopathy, deafness, ataxia, spasticity and cardiomyopathy. Treatment is symptomatic with provision of appropriate footwear, splints or orthopaedic procedures to maintain mobility. The demonstration of genetic markers and the application of nerve conduction studies allows early and correct diagnosis in those at risk. When many single nerves are damaged one by one, this is described as mononeuritis multiplex. Damage to the brachial or lumbosacral plexus may produce widespread limb weakness which does not conform to the distribution of any one peripheral nerve. A knowledge of the anatomy and muscle innervation of the plexuses and peripheral nerves is essential to localise the site of the lesion and thus deduce the possible causes. Certain systemic illnesses are associated with the development of mononeuropathy or mononeuritis multiplex: diabetes mellitus sarcoidosis vasculitis leprosy (worldwide commonest cause) Entrapment mononeuropathies result from damage to a nerve where it passes through a tight space such as the median nerve under the flexor retinaculum of the wrist. These are often related to conditions such as acromegaly, myxoedema and pregnancy, in which soft tissue swelling occurs. When damage to C5C6 is more proximal, nerve to rhomboids and long thoracic nerve may be affected. A combined ulnar and median nerve lesion will produce a similar picture in the hand but with involvement also of flexor carpi ulnaris and pronator teres. When trauma is the cause of brachial paralysis, early referral to a specialist unit with experience in the surgical repair of plexus injuries is advised. Scalenius medius Scalenius anterior Plexus Symptoms Pain in the neck and shoulder with paraesthesia in the forearm, made worse by carrying a suitcase, shopping bag, etc. Subclavian artery 1st rib Subclavian vein Signs Sensory loss in a T1 distribution. Plain radiology of the thoracic outlet may reveal a cervical rib or prolonged transverse process. Nerve conduction/electromyography will distinguish this from other peripheral nerve lesions. Arteriography or venography is occasionally necessary if there are obvious vascular problems. Treatment In middle-aged people with poor posture and no evidence of abnormality on plain radiology, neck and postural exercises are helpful. In younger patients with clinical and electrophysiological changes supporting the radiological abnormalities, exploration and removal of a fibrous band or rib may afford relief. Corticosteriods are normally given though the value of immunotherapy is uncertain. Clinical features Severe pain around the shoulder and down the inside of the arm. Symptoms start with paraesthesia in the hand and progress slowly to involve all lower plexus structures with wasting, weakness, reflex & sensory loss. Wasted spinati Damaged by: [as for Long thoracic nerve (above)] Carrying heavy objects over shoulder (rucksack or pitchfork) Results in: Weakness of abduction of arm (supraspinatus) Weakness of external rotation of arm (infraspinatus).

All domestic species have the distal extremity of the fibula medicine vending machine generic 500 mg baycip with amex, forming the prominent lateral malleolus of the hock medications given to newborns discount 500mg baycip fast delivery. The lateral malleolus is fused to medicine 4 you pharma pvt ltd order baycip 500 mg line the tibia in the horse but is a separate small bone articulating with distal tibia and tarsal bones in ruminants. The tarsus (hock), like the carpus in the thoracic limb is composed of multiple small bones; it corresponds to the human ankle. The calcaneus, which corresponds to the human heel, acts as a lever for the muscles extending the hock. In the horse, the central row of tarsal bones is reduced to a single central tarsal bone. The bones of the distal row are numbered 1 to 4 from medial to lateral, with tarsal bones 1 and 2 fused into a single bone. The metatarsus and digits of the pelvic limb are similar to the metacarpus and digits of the thoracic limb. The remaining two-thirds of bone weight consists of inorganic calcium and phosphorus salts in the organic framework. About 80% of these salts are calcium phosphate, and the remainder is primarily calcium carbonate and magnesium phosphate. The calcium phosphate is primarily found in hydroxyapatite crystals formed with calcium hydroxide. These salts give hardness and rigidity to bones and make them resist the passage of x-rays. If the inorganic salts are removed by soaking a bone in dilute acid, the resulting decalcified bone will retain its original form but will be flexible enough to be tied in a knot. On the other hand, if the organic matter is removed by charring in a furnace so that only the inorganic salts remain, the bone will retain its form but be brittle and break unless handled with extreme care. Mature bone consists of osteocytes (bone cells) surrounded by an intercellular matrix composed of calcified osteoid material. A system of tiny canals called canaliculi connects the lacunae within the substance of the bone. Even though bone is highly vascular, with capillaries close together, the canaliculi transmit tissue fluid that is essential for maintaining the life of the osteocytes. Both the lacunae and canaliculi are formed because cytoplasmic processes connect the osteoblasts (bone-forming cells) at the time the osteoid material is laid down. Thus the cells and their processes act as a mold until the osteoid tissue is set and mineralized. The cytoplasm is then partially withdrawn, leaving the cells, now known as osteocytes, in the lacunae, which are connected by canaliculi containing cytoplasmic extensions. Cancellous bone, or spongy bone, consists of a network of fingerlike bony spicules, or trabeculae. The central (C) and perforating (P) canals contain blood vessels, nerves, and lymphatics. An osteon is telescoped to show the concentric layers of bone that surround a central canal. Interstitial lamellae of bone fill the space between osteons, and the inner and outer surfaces are formed by inner and outer circumferential lamellae. Flat bones between two layers of compact bone, as in the skull, are also cancellous. The spicules of bone are arranged so as to resist stresses and strains imposed on the bone by weight or pull of muscles. Compact bone, found in the shafts of long bones, consists primarily of many laminated tubes known as osteonal systems (formally termed haversian systems). Each osteon consists of one central canal containing vessels and nerves surrounded by circular plates of bone (osteonal lamellae) forming the laminated cylinder. These plates are laid down in a centripetal fashion (from the periphery toward the center). After the bone is formed, the osteoblasts that became embedded in the bone substance are called osteocytes. In general these osteons are added on the periphery of the shaft of a bone as the bone increases in diameter. Osteoblasts usually come from mesenchymal cells, the parent cells of all connective tissues. The osteoblasts divide readily, but only a portion of the new cells actually secretes osteoid substance and forms bone; the rest is held in reserve as the osteogenic layer of the periosteum and endosteum within the marrow cavity and central canals. These reserve cells divide and form more osteoblasts whenever more bone is needed, as in repair of fractures, response to stress, or growth. Because the intercellular matrix is unyielding, bone can be added only on the surface, and the osteocytes (mature osteoblasts) probably have lost the ability to divide. As the shaft of a long bone enlarges in diameter as a result of the activity of the osteogenic layer of the periosteum, bone along the inner surface is normally resorbed to increase the size of the marrow cavity. Resorption of bone may also occur under abnormal conditions, such as during a period of calcium defi- Figure 5-3. Whenever bone is resorbed (under normal or abnormal conditions), large multinucleated cells called osteoclasts (bonedestroying cells) are usually found. These cells, derived from macrophages, take an active part in bone destruction by releasing organic acids and enzymes. Calcification of tissue other than osteoid is usually associated with some pathologic process. Regardless of the location, the sequence of actual bone formation consists of osteoblasts laying down osteoid tissue that is subsequently calcified under the influence of the enzyme alkaline phosphatase. The environment in which bone forms determines whether the type of ossification is endochondral or intramembranous. Endochondral (Intracartilaginous) Ossification During fetal development, most of the skeleton first develops as a cartilage pattern or model, and then the cartilage of this model is gradually replaced by bone. The center of ossification that develops in the midshaft region of a long bone is the primary ossification center. These ossification centers grow and expand, but a region of cartilage, the physis, still separates the centers during growth and development. Chondrocytes within this region continue to proliferate and produce cartilage to provide this separation and thus allow for continued growth in the length of the long bone. The midshaft region of a long bone that contains the primary ossification center is the diaphysis; each end that contains a secondary ossification center is an epiphysis. As animals grow and mature, the region of cartilage that separates the bony diaphysis and epiphyses continues to narrow. The epiphyseal plate, another term used to describe this region of cartilage in growing animals, emphasizes how narrow it may become. When the cartilage in the epiphyseal plates is completely replaced by bone, increases in length, hence growth in stature of the animal, is impossible.

The placenta functions as the pregnancy organ that delivers nutrients, exchanges respiratory gas, and eliminates toxic waste. The placenta is also an important endocrine organ producing hormones to support and sustain pregnancy and plays a critical role in prevention of pregnancy rejection. Impairment in placental development and/or function has a profound impact on pregnancy outcome. Accumulating data suggest that the placenta plays a critical role in the future health of the fetus such as the risk for adult-onset cardiovascular disease among other diseases. The outer surface of the blastocyst differentiates into trophoblastic cells and produces an overlying syncytial layer that adheres to the endometrium. Implantation of the blastocyst then commences as the syncytiotrophoblast cells penetrate the decidualized endometrium. Endometrial gland secretions provide nourishment to the embryo at this early stage. Spaces are then developed within the syncytiotrophoblast and form anastomosis with maternal vascular sinusoids, thus establishing the first (lacunar) uteroplacental circulation. The placental circulation then develops with finger-like projections into the maternal blood spaces. These projections extend from the chorion and form the primary villi with an inner layer of cytotrophoblast and an outer layer of syncytiotrophoblast. The primary villi become secondary villi with the invasion of the extraembryonic mesoderm and finally become tertiary villi as embryonic blood vessels develop within them. In the early stages of placental development, cytotrophoblasts invade the endothelium and smooth muscle of endometrial spiral arteries, releasing them from maternal influences. The fully formed human placenta is termed hemochorial because the maternal blood is separated from the fetal blood only by elements of the chorion. Growth in size and thickness of the placenta continues rapidly in the first trimester and into the second trimester of pregnancy. The term placenta has a fetal portion, the chorion frondosum, and a maternal portion, the decidua basalis, and covers 15% to 30% of the decidua of the endometrial cavity. Note the presence of spaces developed within the syncytiotrophoblast and forming anastomosis with maternal vascular sinusoids. The umbilical cord is formed by fusion of the connecting stalk (allantois and umbilical vessels) and the vitelline duct and vessels with cephalocaudal flexion of the embryo. In early embryogenesis, two stalks are seen: the yolk sac, ventrally located and containing the vitelline duct and vessels, and the connecting stalk, caudally located and containing the allantois and the umbilical vessels. With cephalocaudal flexion of the embryo, the connecting stalk fuses with the yolk sac stalk to form the umbilical cord. The umbilical cord in its early development is inserted in the lower ventral portions of the embryo, is short and thick, and contains the allantois, the vitelline duct and vessels, and the umbilical vessels. The amnion covers the umbilical cord and becomes continuous with the outer epithelial layer of the embryo. The umbilical cord elongates and thins out with the development of the anterior abdominal wall. As the placenta grows, it tends to expand preferentially in regions with sufficient myometrial perfusion and atrophy in areas with suboptimal blood supply. The umbilical cord consists of two umbilical arteries and one vein, which are surrounded by mucoid connective tissue-Wharton jelly. Note that the placenta is slightly more echogenic than the surrounding endometrium. Note that the placenta in A and B has a uniform homogeneous echotexture and is slightly more echogenic than the surrounding endometrium and uterine wall. By 12 to 13 weeks of gestation, the placenta is easily seen on ultrasound and appears slightly echogenic with uniformed homogeneous echotexture. Note that the transvaginal approach clearly outlines placental borders because of increased resolution of the transducer. Transabdominal ultrasound in two pregnancies (A and B), where the placentas appear to be on the anterior uterine walls. In A, the placenta is anterior; however, in B, because of the presence of uterine anteflexion, the posterior uterine wall is seen as closest to the transducer, and thus the placenta is posterior. During the first trimester ultrasound examination (see Chapter 5), the location of the placenta in the uterus should be reported. Identifying the location of the placenta on the first trimester ultrasound is not as easy as in the second trimester given the presence of uterine flexion and extension. Indeed, inaccuracies can be introduced especially when the placenta appears to be in the lower uterine segment. In order to improve accuracy of placental localization on the first trimester ultrasound, we recommend identifying the cervix and the anterior and posterior uterine walls before describing the placental location. The placental size, thickness, location within the endometrial cavity, and echogenicity can also be evaluated by ultrasound in the late first trimester of pregnancy. The assessment of biometric dimensions of the placenta is infrequently performed on prenatal sonography today, unless in rare pathologic conditions or for research purposes. Abnormal placental findings on first trimester ultrasound, such as masses, multiple cystic spaces, or large subchorionic fluid collection, should be noted and followed up. Transabdominal ultrasound in two pregnancies (A and B), where the placentas appear to be on the posterior uterine walls. In A, the placenta is anterior, and the presence of uterine anteflexion gives an erroneous impression of a posterior location of the placenta. Quantitative assessment of placental vascularization may be useful for predicting pregnancy complications and adverse events. Note the differences in blood flow velocities between the maternal and fetal circulation, with the maternal circulation showing a low impedance pattern.

The atlas articulates with the occipital condyles of the skull cranially and with the axis caudally symptoms uti in women discount baycip 500mg without a prescription. The body of the axis features a cranial projection called the dens (for its resemblance to symptoms exhaustion order baycip 500mg without prescription a tooth) treatment centers in mn discount 500 mg baycip with mastercard, which articulates with the atlas in a pivot joint. The remaining cervical vertebrae are similar to one another, with small spinous processes and rather large transverse and articular processes. With the exception of the last cervical vertebra (C7), each cervical transverse process contains a transverse foramen through which passes the vertebral artery. Thoracic vertebrae are characterized by well-developed spinous processes and articular facets for the ribs. Costal fovea on the bodies of adjacent thoracic vertebrae form cavities for articulation with the heads of the ribs. Each transverse process also features a fovea for articulation with the tubercle of the rib of the same number as the vertebra. The articular processes are more robust than those of the thoracic vertebrae, but not as large as the articular processes in the cervical region. The body and caudal articular processes of the last lumbar vertebra articulate with the sacrum. The sacral vertebrae are fused to form a single wedge-shaped bone, the sacrum, which articulates with the last lumbar vertebra cranially, with the first caudal vertebra caudally, and with the wings of the ilia craniolaterally. The intervertebral foramina of the sacrum are represented by dorsal and ventral rows of sacral foramina on dorsal and ventral sides of the sacrum. These foramina, as with other intervertebral foramina, give passage to spinal nerves. Depending on the length of the tail, the number varies considerably from species to species and even within the same species. Size of the vertebrae decreases rapidly in a caudal direction, until the last few caudal vertebrae are merely small rods of bone. As animals lack the curved, fused coccyx of human beings, the term coccygeal to describe the vertebrae of the tail is discouraged. Sternum and Ribs the sternum forms the ventrum of the bony thorax and gives attachment to the costal cartilages of the ribs as well as providing a bony origin for the pectoral muscles. The cranial extremity of the sternum is the manubrium; the middle portion is the body; and the caudal extremity is the xiphoid process. The sternum consists of individual bones called sternebrae that tend to fuse as age advances. The number of sternebrae (excluding the manubrium and xiphoid from the count) varies with species as follows: pig, four; ruminants and horses, five; and in the dog, six. Usually, the number of pairs of ribs is the same as the number of thoracic vertebrae. Rarely, an extra rib or pair of ribs lies either cranial or caudal to the thoracic vertebrae. A typical rib consists of a shaft, a sternal extremity ventrally, and a vertebral extremity dorsally. Except for the last one or two pairs of ribs, the sternal extremity is connected to the sternum by the costal hyaline cartilage; ribs so attached are called sternal (true) ribs. The vertebral extremity consists of a spherical head connected to the rib by a constricted neck and a tubercle that articulates with the transverse process of a thoracic vertebra. The head articulates with the bodies of two adjacent vertebrae at the costal fovea. The ribs caudal to the sternal ribs are called asternal (false) ribs because they are not directly connected to the sternum. The costal cartilages at the ventral extremity of most of the asternal ribs overlap and thus indirectly connect the asternal and sternal ribs. Sometimes the last pair or two of ribs have no connection with other ribs at the ventral end. The spaces between adjacent ribs are the intercostal spaces, numbered to correspond to the number of the rib cranial to the space. Appendicular Skeleton the appendicular skeleton is made up of the bones of the limbs. The bones of the thoracic limb are compared to those of the pelvic limb by region in Table 4-4. Thoracic Limbs the scapula (shoulder blade) in all animals is a relatively flat triangular bone. The distal portion is its ventral angle, and it forms the only true joint between the scapula and another bone in most domestic animals. Birds and primates possess a clavicle (collarbone), which forms a joint with the scapula, but in most quadrupeds, the clavicle is represented only by the clavicular tendon, a connective tissue band within the brachiocephalicus muscle. The coracoid in humans and domestic mammals has been reduced to the coracoid process (a bony prominence), which protrudes mediad from the scapula near the ventral angle in most species. The lateral face of the scapula has a ridge called the spine extending from the ventral angle to the dorsal border. In carnivores and ruminants, the distal end of the spine is flattened to form the acromion process. The spine divides the lateral face into the supraspinous fossa, which is cranial to the spine, and the infraspinous fossa, which is caudal and ventral to the spine. The costal (medial or deep) face of the scapula gives attachment to some of the muscles that connect the limb to the body. The humerus (arm bone) is a long bone that varies only in minor details from one animal to another. The proximal end bears a rounded, articular head that participates with the ventral angle of the scapula to form the scapulohumeral (shoulder) Table 4-4.

A, Scapula; B, scapulohumeral (shoulder joint); C, humerus; D, elbow joint; E, antebrachium (radius & ulna); F, carpus; G, metacarpus; H, digit (phalanges). The proximal end of the humerus also features a number of irregular tuberosities and tubercles, providing sites of attachment to muscles of the shoulder region. The palpable prominence produced by this end of the humerus is called the point of the shoulder. The distal end of the humerus forms a spoollike condyle that articulates with the proximal ends of the radius and ulna in the elbow. In mammals, the radius is the larger of the two, although in birds it is smaller than the ulna. The radius can be felt directly beneath the skin on the medial side of the forearm. The prominent olecranon process (point of the elbow) is found in all mammals proximal and caudal to the elbow joint. In the horse, the proximal portion of the shaft of the ulna is well developed but fused to the radius; the distal ulna is absent. The ox, sheep, goat, and pig each have a complete ulna, but with little or no movement between the ulna and radius.

Please note that variant and atypical forms make this a more complex process than the flowchart necessarily suggests (Schiffmann and van der Knaap, 20091)! Cortex White matter Basal ganglia T1 T2 Normal (after ~ 18m) or or T1 T2 Leukoencephalopathy or Leukodystrophy T1 T2 T1 T2 T1 T2 Hypomyelination. Specific scenarios · Unilateral hemi-syndrome: consider migraine or epilepsy (the duration of disturbed sensation will help differentiate). Proximal arm/shoulder pain or dysaesthesia often precedes the weakness of neuralgic amyotrophy. Much more commonly a child with developmental disability will show indifference to pain: he feels (and withdraws automatically from) painful stimuli but shows little emotional distress. Such disturbances will typically be reported in patchy distributions that do not correspond to anatomical segmental or peripheral nerve territory distributions. Paroxysmal extreme pain disorder · the preferred name for what was previously known as familial rectal pain syndrome. Difficulties raising head from pillow, combing hair, brushing teeth, shaving, raising arms above head, getting up from chair, stairs and use of banisters, running, hopping, jumping. Difficulties opening screw cap or door knob, turning key, buttoning clothes, writing, falling on uneven ground, tripping, hitting curb, difficulty in heel walking, toe walking, foot drop. Distal weakness is usually due to neuropathy (any), but also some muscle diseases (EmeryDreifuss, myotonic dystrophy, dysferlinopathy, Miyoshi myopathy). Difficulties bending forward, lifting head off the bed, respiratory involvement, nocturnal hypoventilation, and diaphragmatic weakness; seen in congenital myopathies and glycogen storage disorders. Antenatal onset suggested by polyhydramnios, reduced foetal movements, unusual foetal presentation in labour, contractures (arthrogryposis including foot deformity), congenital dysplasia of the hip. Associated features/system enquiry · Toe walking: Duchenne, Becker, EmeryDreifuss, CharcotMarie Tooth. Examination · Examine parents and siblings: especially when considering neuropathies, myotonic dystrophy. This latter is particularly a consideration in the presence of myoclonic seizures (see b p. The six commonest diagnostic groups were leukoencephalopathies (7% combined), neuronal ceroid lipofuscinoses (5% combined), mitochondrial diseases (5%), mucopolysaccharidoses (4%), gangliosidoses (4%), and peroxisomal disorders (3%). Ask about history of sudden infant death, unexplained illness, or neurological presentations in family members. The epidemiology of progressive intellectual and neurological deterioration in childhood. Clues from imaging, electrophysiology and ophthalmology examination For approach to white matter abnormalities see b p. It can be hard to tell whether the problem is, in fact, longstanding, but has recently come to light due to increasing academic expectations. Parental observations should be supplemented by reports from schoolteachers and/or educational psychologists. Examination the child will be older and a formal (adult style) neurological examination with assessment of higher mental function (see Box 1. Non-rapid eye movement sleep Stage 1 (510% of sleep) · Occurs at sleep onset or following arousal from another stage of sleep (see Figure 3. Rapid eye movement sleep Physiologically very different: · Brain metabolism is high. Examination Pay particular attention to physical factors that may disturb sleep. Excessive daytime sleepiness Likely to be due to poor nocturnal sleep hygiene but consider obstructive sleep apnoea and narcolepsy (under-recognized) (see b p. Disturbed episodes related to sleep (parasomnias) these are recurrent episodes of behaviour, experiences, or physiological changes that occur exclusively or predominantly during sleep. Decide whether these are primary, or secondary to neurodevelopmental or neuropsychiatric issues (see b p. Measures the time taken to get to sleep during 5 opportunities at least 2 h apart during the day. Conceptual framework Speech and language disorder · Secondary to cognitive disability, hearing impairment or environmental adversity. Neuromotor speech disorders Apraxia Abnormal planning, sequencing, and coordination of articulation not due to muscle weakness. Dysarthria Weakness/paralysis of the musculature of speech (larynx, lips, tongue, palate, and jaw). Spastic dysarthria · Due to hemispheric disease (cerebral palsy including Worster Drought syndrome; acquired brain injury including stroke, tumour, neurosurgery; cytotoxic and other drugs. Secondary dysarthria Children with benign epilepsy with centro-temporal spikes (see b p. Problems with this stage are usually due to impaired control of the tongue during swallowing causing difficulty keeping liquid in the mouth, difficulty chewing food, pocketing of food in the vestibule of the mouth, or aspiration of food during inhalation. Problems with this phase may lead to retention of food in the pharynx and aspiration. Liquids usually fall by gravity; peristaltic waves push solids along (innervated by X). Problems with this phase can occur when there are motility disorders, mechanical obstruction or impaired opening of the lower oesophageal sphincter. Causes of swallowing disorders in children · Structural abnormality: oesophagitis, gastro-oesophageal reflux, oesophageal strictures. Assessment of disordered swallowing A multidisciplinary team approach is beneficial in the assessment and management of children with swallowing problems. History · Feeding history: onset of problem (acute or chronic), severity (drooling, choking, coughing with feeds), voice change, nasal regurgitation, retention of food in the mouth, symptoms of gastro-oesophageal reflux. Other causes include: · Weakness: myopathic (generally proximal) or neuropathic (peripheral). May suggest susceptibility to migrainous processes though such findings are common and may be misleading! Examine shoes for evidence of scuffing and wear at the toe; · observe for pronator drift (see b p. Falls and unsteadiness due to phenomena other than ataxia Dyspraxia · Also known as developmental coordination disorder. Consider whether ataxia is acute or chronic, progressive or non-progressive, or episodic. A parainfective subacute onset ataxia is particularly characteristic 714 days post-Varicella. Slowly progressive ataxias (over months to years) with initial symptom-free period · Nearly all genetically determined progressive ataxias of older childhood are both extremely rare and dominantly inherited with high penetrance so that a family history will be informative (see b p.
