Gross and microscopic lesions of Bolivian hemorrhagic fever (BHF) are described in 10 rhesus monkeys that survived from 30 to 78 days after subcutaneous inoculation with a dose of 10(3) plaque-forming units (PFU) of Machupo virus, a dose which produces a severe and generally fatal disease. Six of the monkeys had been given low doses of homologous immune globulin when initial signs of infection appeared. Monkeys exhibited clinical signs in two phases. The initial signs of acute infection which began to appear about 1 week following inoculation included: diarrhea, depression, anorexia, dehydration, and skin rash. The survivors of this early phase of the illness usually showed improvement before relapsing into the second (or chronic) phase, which was characterized clinically by central nervous system disturbances including incoordination, tremors, convulsions, paresis, and muscle atrophy. Microscopic lesions were similar in both immune globulin-treated and untreated animals. These included widespread lymphoreticular infiltrates in the walls and adventitia of blood vessels of the brain, spinal cord, pancreas, intestine, liver kidney, adrenal, parathyroid, heart, and skeletal muscle. Diffuse lymphocytic infiltrates not confined to the vascular or perivascular tissues were present to a variable degree in many of these and other organs. Several monkeys exhibited lymphocytic inflammation of the choroid, meninges, peripheral nerves, and ganglia.

Ten clinically intact weaned piglets were experimentally intoxicated by intravenous injection of lipoproteide-free lipopolysaccharide endotoxin according to Westphal of E. coli O 127:B8. Severe endotoxin shock with all clinical manifestations of experimental coli-enterotoxaemia was induced in all animals and included circulatory disorder with tachycardia, intermittent pallor and/or cyanosis, symptoms of severe systemic intoxication, neurological symptoms, such as lack of coordination, hindleg staggering, spasm, paresis, paralysis, changes in respiration, such as rise in respiratory frequency and deepened breathing premortal deceleration of respiration and gasping for breath, temperature, variation, including hyperthermia and aggravating hypothermia, gastro-intestinal symptoms, such as temporary vomiting and persistent diarrhoea, leucopenia, eosinopenia, variation of haematocrit, edematisation, increased transudation, congestion, and gastro-intestinal shock lesions. Eight animals died. These experiments quite obviously have confirmed that endotoxin shock is the common pathogenetic principle behind all forms of coli-entertoxaemia (i.e, the forms of edematisation, cardiovascular failure, and gastro-intestinal processes.) Lipopolysaccharide endotoxin alone may be responsible for the development of both edemas and neurotoxic symptoms (edema disease) and diarrhoea (gastro-intestinal form of coli-enterotoxaemia). The pathogenetic relevance of additional toxins (neurotoxin and enterotoxin) is discussed under this aspect.

During February 1975, a tremorgenic neurotoxicosis decimated a herd of cattle in the northern Transvaal. This hitherto unidentified disease was characterized by hypersensitivity, incoordination, a peculiar stiff-legged gait of the hind legs, severe generalized tumors of the sketetal muscles, progressive paresis, paralysis and constipation. The most notable gross pathological lesions were degenerative and necrotic changes in certain skeletal muscles, haemorrhages on the serosal surfaces, especially on the dorsal aspect of the rumen, and gastro-intestinal stasis. Microscopical examination of the central nervous system revealed cytopathological changes consisting of degeneration and necrosis of the large motor cells in the ventral horns of the spinal cord and bigger neurones in numerous nuclei of the medulla oblongata, midbrain and thalamus. By feeding the suspect ration and its component parts to cattle and sheep, it was possible to identify mouldy sorghum beer residue as the toxic component in the ration. A. clavatus, the dominant fungus on the toxic residue, was readily isolated in pure culture. The entire syndrome was then reproduced in a yearling Friesland steer dosed with pure cultures of the A. clavatus isolate grown on autoclaved non-toxic sorghum beer residue. The toxic principle is not known, but it does not appear to be patulin, tryptoquivalone, tryptoquivaline, or any other known tremorgen.

Hexachlorophene (HCP) intoxication in swine was studied as a possible model of HCP poisoning in human beings. Swine were topically or orally given HCP each day, and observations were made on central nervous system function, hematologic measurements, serum chemical analyses, necropsy, microscopic examination of tissues, and concentrations of HCP residues in blood and tissue. Intoxication was observed in orally exposed swine, but the syndrome was not consistently produced in topically exposed swine. Signs and microscopic lesions were all related to dysfunction of the central nervous system, e.g., incoordination, paresis, and status spongiosus. Occurrence of signs and lesions, mortality rates, and concentrations of HCP residue were positively correlated with the dosage of HCP given.

We investigated motor function and pain sensation in the gracile axonal dystrophy (GAD) mutant mouse, using the tail-flick test and the rotarod test. GAD (gad/gad) and normal sib mice (gad/+ or +/+) were used between 5 and 11 weeks of age, during which time the behavioral signs of GAD mice shifted from sensory ataxia (about 4 to 8 weeks of age) to paresis (after about 9 weeks of age). In the tail-flick test, significant shortening of latency was observed at 6 and 8 weeks of age in female GAD mice, in comparison with normal female mice. This may be related to dysfunction or degeneration of axons in the fasiculus gracilis, whose collaterals are thought to control the transmission of nociceptive information. In the rotarod test, a cumulative chi 2 test showed significant reduction in the performance times of GAD mice beginning at 5 and 6 weeks of age in males and females, respectively, indicating that the rotarod test can detect the development of motor incoordination as early as these ages. The performance times of GAD mice dropped sharply from 9 weeks of age onwards, and this is believed to reflect the progression of paresis. The rotarod test therefore appears to be a good method of quantifying behavioral changes in GAD mice and to be applicable both to objective selection of GAD mice before 8 weeks of age and to evaluation of drugs to treat ataxia or paresis.

In the United States, an estimated 274,000 persons have cerebral palsy (CP), a neurologic condition defined as a group of nonprogressive disorders in which an abnormality of the central nervous system can result in motor dysfunction (e.g., paresis, involuntary movement, and incoordination). CP is the third leading cause of the need for assistance with basic life activities and the fifth leading cause of activity limitation. An adult with CP may require adaptive housing to improve accessibility (e.g., to entrances and toilet facilities), attendant care to assist with activities of daily living, and/or nursing care to meet specific health-care needs. These needs can be met through a variety of residential accommodations. However, because the residential environment has a considerable impact on well-being and quality of life, the accommodations should be in the least restrictive environment and, when possible, community-based. This report summarizes an assessment of characteristics of adults with CP to determine which factors are associated with placement in a more restrictive environment.

The literature contains about 500 cases of equine leucosis, though the reports are deposited in a great number of journals and vary considerably concerning particular topics. During the last years there has been a remarkable increase of publications about this syndrome in the equine. The clinical leucosis key recommended by us has been confirmed in principle considering the latest literature. In about 70 individual symptoms which can be clinically observed in equine with leucosis 11 can be considered as main symptoms because of their frequency; they are again classified in primary (lymph node tumours including splenomegaly--loss of condition, weakness--cachexia, weight loss, periphery oedema), secondary (anorexia, inappetence--fever--paleness of mucous membrane--anaemia--tachycardia) and accessory (incoordination--tachypnoea, dyspnoea--apathy, lethargy) main symptoms. Furthermore in future it will be necessary to take into more consideration the symptoms "recurrent colic" and "hydrothorax" within differential diagnosis. The main symptom "incoordination" (ataxia, asynergy, paresis, paralysis) is used by us more precisely only in case of impairment of nervous system by neoplastic infiltrations and does not signify as possible symptoms of general physical weakness, for example faltering, staggering, tumbling or lameness. The morphological classification follows further on our previous recommendation. There exist generalized forms with tumour infiltrations in abdominal and in thoracic cavity as well as especially in peripheral lymph nodes. On the other hand there are characteristic manifestations in certain regions of the body, which establish distinctly the clinical symptomatology. They are marked as regional multicentric forms with the main localizations "mediastinal", "splenic", "mesenteric" or "intestinal".(ABSTRACT TRUNCATED AT 250 WORDS)

The patient, a man aged 57, was admitted to our clinic on May 1, 1987, because of severe vertigo and unsteadiness in standing. Since the age of 55 he had been suffered from hypertension and atrial fibrillation. In September, 1986, he experienced vertigo but recovered soon without therapy. On April 25, 1987, while working, he noticed severe vertigo, nausea and vomiting. He was admitted to a hospital, and then transferred to our clinic. On admission, he was alert and the mentality was normal. Slight ptosis abducent nerve paresis, hypalgesia on the forehead, nose and cheek, facial paresis of peripheral type and hypacusis were detected on the left side. No anisocoria was observed. Sweating was impaired over the left side of the face. Elevation of the soft palate was limited on the left side and the tongue deviated to the left on protrusion. Dysarthria was detected. Though there was no muscular weakness in the extremities, incoordination and dysmetria were noted in the left arm and leg. He could not stand up because of vertigo and unsteadiness. There was no sensory disturbance in the trunk and extremities. Deep tendon reflexes were well elicited and no pathological reflex was observed. These clinical manifestations, except for the ipsilateral palatal and lingual disturbances, were typical of the lateral inferior pontine syndrome caused by occlusion of anterior inferior cerebellar artery, and the lesion was clearly demonstrated by horizontal and coronal MRI. The palatal and lingual disturbances might be due to the involvements of the corticobulbar tracts of the 10th and 12th nerves after the fibers had decussated.

The feeding of monensin as a coccidiostat in three separate flocks of turkeys was associated with increased mortality, posterior paresis, and a skeletal muscle myopathy. Mortality attributed to the disease was 1.65%, 1.86%, and 4.80% in the three flocks. Samples of monensin-supplemented feed fed to the flocks when showing clinical signs contained 88, 85, and 106 g/ton of complete feed, respectively. Clinically, the turkeys showed posterior paresis, inability to rise, incoordination, reluctance to move, and leg trembling and weakness. Necropsy findings included consistent lesions of pallor within the type I muscles of the legs, wings, and backs. Microscopic lesions included myofiber degeneration and necrosis with massive cellular proliferation interpreted as sarcolemmal nuclei proliferation. Occasional axonal degeneration with loss of axons was present in peripheral nerves embedded in the damaged musculature. In the youngest flock, multifocal areas of acute coagulation necrosis of the myocardium were also present. These outbreaks occurred following intake of monensin in the complete feed at levels considered therapeutic; however, no associated predisposing clinical condition, drug/toxin interaction, or excessive monensin levels in the feed could be demonstrated.

The pattern of swallowing by which the oral bolus reaches an air-containing oropharynx is called an 'open swallow' whereas the sequence in which the oropharynx is collapsed on the arrival of the bolus is called a 'closed swallow'. The significance of this distinction was further analyzed by a correlation with other laryngeal and pharyngeal functions during swallowing in a cineradiologic study in 75 dysphagic patients and 50 asymptomatic volunteers. The relative incidence of open and closed type swallows was similar in the two groups. The maximum elevation of the pharynx and larynx was the same in open and closed swallow, although in individuals with an open swallow the elevation occurred later than in individuals with a closed swallow. Epiglottic movement disturbances, defective closure of the laryngeal vestibule, pharyngeal constrictor muscle paresis, cricopharyngeal incoordination, cervical esophageal webs and Zenker diverticula were significantly more common in individuals with an open pharyngeal swallow than in those with closed swallowing.
