Pure word deafness has been variously conceptualized as a form of auditory agnosia or a subcortical sensory aphasia. Pure word deafness is most commonly associated with bilateral lesions of the temporal cortex or subcortical lesions whose anatomical effect is to damage the primary auditory cortex or isolate it. Very rarely pure word deafness has been associated with bilateral brainstem lesions at the level of the inferior colliculi. Pure word deafness after resection of a tectal plate glioma with preservation of wave V of brain stem auditory evoked potentials. Brain 1987; 110: 381403 Cross References Agnosia; Amusia; Aphasia Pursuit Pursuit, or smooth pursuit, eye movements hold the image of a moving target on the fovea, or during linear self-motion, i. Impaired pursuit may result from occipital lobe lesions, and may be abolished by bilateral lesions, and may coexist with some forms of congenital nystagmus. Cross References Nystamgus; Saccades; Saccadic intrusion, Saccadic pursuit Pyramidal Decussation Syndrome Pyramidal decussation syndrome is a rare crossed hemiplegia syndrome, with weakness of one arm and the contralateral leg without involvement of the face, due to a lesion within the pyramid below the decussation of corticospinal fibres destined for the arm but above that for fibres destined for the leg. Parietal lobe lesions may produce inferior quadrantic defects, usually accompanied by other localizing signs. Damage to extrastriate visual cortex (areas V2 and V3) has also been suggested to cause quadrantanopia; concurrent central achromatopsia favours this localization. As with hemiplegia, upper motor neurone quadriplegia may result from lesions of the corticospinal pathways anywhere from motor cortex to cervical cord via the brainstem, but is most commonly seen with brainstem and upper cervical cord lesions. Cerebellar hypoplasia and quadrupedal locomotion in humans as a recessive trait mapping to chromosome 17p. No specific investigations are required, but a drug history, including over the counter medication, is crucial. The condition may be confused with edentulous dyskinesia, if there is accompanying tremor of the jaw and/or lip, or with tardive dyskinesia. Radiculopathy A radiculopathy is a disorder of nerve roots, causing pain in a radicular distribution, paraesthesia, sensory diminution or loss in the corresponding dermatome, and lower motor neurone type weakness with reflex diminution or loss in the corresponding myotome. There may be concurrent myelopathy, typically of extrinsic or extramedullary type. Most radiculopathies are in the lumbosacral region (6090%), followed by the cervical region (530%). Recognized causes of radiculopathy include · Structural lesions: Compression: disc protrusion: cervical (especially C6, C7), lumbar (L5, S1) >>> thoracic; bony metastases; spondylolisthesis; fracture; infection; Root avulsion. Recognized causes include connective tissue disease, especially systemic sclerosis: cervical rib or thoracic outlet syndromes; vibration white finger; hypothyroidism; and uraemia. Associated symptoms should be sought to ascertain whether there is an underlying connective tissue disorder. Rebound Phenomenon this is one feature of the impaired checking response seen in cerebellar disease, along with dysdiadochokinesia and macrographia. It may be demonstrated by observing an overshoot of the outstretched arms when they are released suddenly after being pressed down by the examiner or suddenly releasing the forearm flexed against resistance so that it hits the chest (StewartHolmes sign). Although previously attributed to hypotonia, it is more likely a reflection of asynergia between agonist and antagonist muscles. Recruitment Recruitment, or loudness recruitment, is the phenomenon of abnormally rapid growth of loudness with increase in sound intensity, which is encountered in patients with sensorineural (especially cochlear sensory) hearing loss. Cross Reference Reflexes Recurrent Utterances the recurrent utterances of global aphasia, sometimes known as verbal stereotypies, stereotyped aphasia, or monophasia, are reiterated words or syllables produced by patients with profound non-fluent aphasia. The poet Charles Baudelaire (18211867) may have been reduced to a similar state following a stroke. Red Ear Syndrome Irritation of the C3 nerve root may cause pain, burning, and redness of the pinna. This may also occur with temporomandibular joint dysfunction and thalamic lesions. Reduplicative Paramnesia Reduplicative paramnesia is a delusion in which patients believe familiar places, objects, individuals, or events to be duplicated. The syndrome is probably heterogeneous and bears some resemblance to the Capgras delusion as described by psychiatrists. Reduplicative paramnesia is more commonly seen with right (nondominant) hemisphere damage; frontal, temporal, and limbic system damage has been implicated.
Accelerated soil erosion occurred during the last decade due to the increased frequency of flooding and led to siltation in the river ombrello glass treatment safe 500 mg mildronate. Economic impacts occurred because of losses in soil productivity due to decreases in fertile soil volume treatment for plantar fasciitis buy cheap mildronate 250 mg on-line, losses of nutrients and organic matter, the need for greater quantities of fertilisers to make up for diminished soil fertility as well as the reduction in the life span of dams and reservoir capacities. Environmental impacts arise from 70 4WaterPollutioninRiverBasins the siltation and increased turbidity of waterways. Environmental impacts are not always restricted to those regions where erosion occurs; high levels of nutrients, associated with erosion of agricultural soils, may be transported to the mouth of the Medjerda River and contribute to coastal eutrophication and possibly hypoxic conditions. For this, an interdisciplinary framework was established covering environmental, socio-economical and institutional aspects. Faced with ever-increasing challenges of water resource management in the country, a coherent national water policy is essential. In Tunisia, soils are under serious risk due to long dry periods followed by heavy bursts of intensive rainfall, falling on steep slopes with fragile soils and low vegetation cover. Thus, a strategy for soil and water conservation measures is needed to identify hot spot and vulnerable areas to reduce sediment loads and their associated impacts. Also, for better water quality assessment in the Medjerda catchment, an innovative high resolution monitoring approach is recommended for the future. Recently, action has been taken in Tunisia to increase public awareness for water resources management and environmental preservation. Although nitrogen and phosphorus loads have been steadily decreasing, further measures are needed to achieve a range of environmental objectives. Catchment wide management options are planned in the Elbe River Basin Community, which is an association of ten German federal states. Main confluents are the Vltava in the Czech Republic and the Saale as well the Spree/Havel system in Germany (Figure 4. This case study will mainly focus on the water management issues in the German part of the catchment. The catchment is characterised by a transitional climate from the humid-oceanic climate of Western Europe to the dry-continental climate of Central and East Europe. Average annual rainfall varies from less than 500 mm in the regions of Thuringia and Saxony-Anhalt to 1,800 mm in the Harz Mountains. The catchment wide average rainfall is 628 mm, which is balanced by an average annual evaporation of 445 mm. Typically, the discharge into the Elbe River is high in late winter and spring due to snow storage and snow melt. The average annual discharge at the German-Czech border is 311 mі/s which increases at the catchment outlet to 861 mі/s. Approximately 60 per cent of the German catchment is used for agriculture, nearly 30 per cent is forest land and less than 10 per cent is covered with settlements. The transboundary catchment has about 25 million inhabitants, 75 per cent of them live in the German part. In addition to Berlin and Hamburg, major cities are Leipzig and Dresden (Figure 4. In 1990, an International Commission for the Protection of the Elbe River was founded. The main objectives of this transboundary organisation are to promote the fair use of river water, especially for municipal users via river bank water extraction and for agricultural water users, while maintaining the health of its aquatic and riparian ecosystems and healthy flora and fauna. Germany, one of the main riparian nations of the Elbe, has established the Elbe River Basin Community for managing the part of the river basin that crosses German state borders. Members of the Community are the federal government and the ten federal states which share a part of the catchment. With the exception of Berlin and Hamburg, water management administration in the German states is hierarchically structured on two or three levels. Recent activities mainly focus on the enhancement of hydromorphological conditions and the improvement of fish migration as well as the reduction of contamination by pollutants and nutrients.
Plantigrade (plahnt-ih-grd) animals have well-developed foot pads treatment deep vein thrombosis generic 500mg mildronate otc, such as those in primates symptoms diagnosis mildronate 500 mg low cost. Plantigrade animals walk with phalanges, metacarpals and metatarsals, and carpal and tarsal bones making contact with the ground. In dogs and cats, nails and claws are keratin plates covering the dorsal surface of the distal phalanx. The dorsal and lateral surface of the claw is covered by the wall, and the ventral surface is the sole. Beneath the wall and sole is the connective tissue dermis, which contains numerous blood tactile (tahck-tl) hair = long, brittle, extremely sensitive hairs usually located on the face; also called vibrissae (v-brihs-), which are technically longer tactile hairs. The arrector pili (ah-rehck-tr p-l) is a tiny muscle attached to the hair Copyright 2009 Cengage Learning, Inc. A = digital pad, B = metacarpal pad, C = carpal pad, D = metatarsal pad, E = dewclaw, F = bulb or heel, G = sole, H = wall, I = frog, and J = ergot. When weight is put on the frog, blood is forced out of the foot to promote circulation of blood throughout the foot. Quicking is the term used to describe trimming the nail or claw to the level of the dermis. Hooves are the horny covering of the distal phalanx in ungulates (uhng-yoo-ltz), or hooved animals, such as equine, ruminants, and swine. Some ungulates have a solid hoof, as in equine, and some have cloven or split hooves, as in Copyright 2009 Cengage Learning, Inc. Skin Deep 209 Quick front leg, they are located above the knee, and in the hind leg, they are located below the hock (Figures 107a and b). No two chestnuts are alike, and they do not change in size or shape throughout an W What is the difference between h horns and antlers? Horns and antlers are protective structures located in the head region of animals. Horns grow from the frontal skull bones and originate from keratinized epithelium. Cornification (kohr-nih-fih-k-shuhn) is the conversion of epithelium into keratin or horn. Horns may be located in different positions, as can be seen in the different ruminant species. Antlers initially are covered with skin called velvet, which the animal rubs off after the skin dies. When the animal rubs off the velvet, the bone is exposed, the antlers lose their blood supply, and the antlers are eventually shed. The ventral surface of the hoof is the sole, which is large in equine and smaller in ruminants and swine. The pad of equine is called the frog and along with the bulb provides shock absorption. The corium (kr-uhm) is the dermis of the hoof and is located under the epidermal surface of the hoof wall, sole, and frog. Vestigial Structures Vestigial, or rudimentary, structures of the integumentary system include dewclaws, chestnuts, and ergots. Dewclaws in dogs usually are found in the forepaw (although they occasionally are seen in the hindpaw) and may be removed within a few days of birth to avoid trauma. Chestnuts are located on the medial surface of the leg; in the Ergot Chestnut (a) (b) Figure 107 (a) Chestnut of a horse. A punch biopsy is a type of incisional biopsy commonly used to obtain full-thickness skin samples. Digital pads of dogs are replaced by the bulbs of the heel (and the frog in equine) in ungulates. An incisional biopsy (ihn-sihshuhn-ahl b-ohp-s) is the removal of a piece of a tumor or lesion for examination (Figure 109).
