Fifty patients were hospitalised at Vientiane during May and June 1975. Infection was caused by consumption of pork meat (som-mou, lap mou and lap leuat). After an incubation period of 8 to 11 days intermittent diarrhoea followed by constant fever and orbital oedema occurred. Several days later diffuse myalgias occurred. Three patients presented neurological symptoms: left hemiplegia flexible paraplegia and limb paresis; these symptoms regressed spontaneously. 87% of the clinically suspected cases had specific serum antibodies (IFI, ID, IE). Hyperleucocytosis and hypereosinophilia were a constant factor. Anti-AH antibodies were detected by the Widal test. The histopathology characteristic of myositis was seen in the 12 muscle biopsies. Also observed was the precystic state of the larvae which is in agreement with the early timing of the samples which were obtained during the 3rd and 4rd week of infection.

The anesthesia routine in the horse is briefly explained. 35 postanesthetic complications resulted from the total of 4364 cases of anesthesia. They are evaluated by means of the duration of anesthesia, the time of paresis, the exemplary courses of enzymes as well as the distribution of race and sex and their ratio towards all cases of anesthesia. Finally a list of demands concerning the operative and postoperative phases is compiled to minimize postoperative myositis (PAM) and lameness (PAL).

Nine puppies suffered from progressive paresis with muscle wasting, hyporeflexia and extensor rigidity. CK-activity in serum was elevated and electrodiagnostic findings were indicative of lower motor neuron disease. Although lesions were also found in the CNS, additional neurological signs were rare, but CSF examination revealed the presence of inflammatory lesions. On pathologic examination, all animals had a disseminated necrotizing myositis. In addition, a disseminated encephalomyelitis was found as well as, in 2 cases, a neuritis. In the lesions of 6 animals protozoal organisms were found which were immunocytochemically identified as Neospora caninum. Our results show that the protozoal myositis-encephalitis syndrome in puppies can be diagnosed in the clinic with high probability. A clinical differentiation between toxoplasmosis and Neospora caninum infection is presently difficult.

The occurrence of high-risk factors for vascular disorders was analysed in a group of 43 patients suffering from diplopia of unknown aetiology. The subjects (25 men and 18 women) were aged between 17 and 78 years. Previously excluded were patients with intracranial or orbital tumors, ocular myositis or myasthenia, multiple sclerosis, endocrine orbitopathy, head trauma, cerebral hemorrhage or aneurysms, leucaemic infiltrates or metastasising tumors. Compared to the control groups of extensive epidemiological studies, the patients showed a higher prevalence of arterial hypertension and diabetes mellitus. Adipositas, lipometabolic disturbance and cigarette smoking were also more frequent. The findings support the hypothesis of a vascular origin of eye-muscle paresis.

A 2-year-old Boston Terrier was referred because of depression and hindlimb and tail paresis. Clinical examination and serum biochemical analysis resulted in a diagnosis of encephalomyelitis and myositis. Results of testing for Dirofilaria immitis were positive. Gross and histologic examination revealed an aberrant adult heartworm infection resulting in thrombosis of the femoral artery and multiple muscular branches, with subsequent muscle necrosis and inflammation in one hindlimb. Additionally, an unusual larval-tissue interaction to microfilariae yielded a multifocal encephalomyelitis in the brain and spinal cord.

A patient with serologically confirmed infection by Borrelia burgdorferi presenting with painful paresis and atrophy of the proximal muscles of both upper extremities and bilateral facial paresis is described. Electromyography showed a neurogenic and myopathic pattern, and creatine kinase was raised. Muscle biopsy revealed the typical signs of focal myositis. Treatment with i.v. penicillin led to dramatic clinical and serological improvement. Muscle biopsy was repeated 2 months later; neurogenic changes were still present, but no inflammatory signs could be seen anymore. Thus, the presented case may be the first reported of meningopolyneuritis accompanied by focal nodular myositis, in the second stage of Lyme borreliosis.

A case of dermatomyositis (DM) with only one abnormal muscle function, bilateral diaphragmatic paresis, is reported. The coexistence of interstitial lung disease allowed us to sample the diaphragm during an open lung biopsy. Characteristic features of myositis were found. Lung volumes, compliance, maximal inspiratory pressure, and transdiaphragmatic pressure gradient (delta Pdi) were lower than normal. Lung recoil pressure was normal. Reversible small airways obstruction was also found. Treatment with prednisone produced dramatic improvement, with all functional values becoming normal except for compliance, which remained slightly decreased. A thorough evaluation of inspiratory muscle strength is advised in all patients with DM in order to identify varying degrees of altered diaphragmatic function.

Compressive lumbar myelopathy is a recognized iatrogenic complication of injecting water-in-oil vaccines into paravertebral sites of laboratory animals and chickens. Herein, we report the histologic and ultrastructural features of a similar complication in a herd of cattle. Iatrogenic posterior paresis developed over 34 days in 56 of 610 cows (9.2%) following injection of a commercial bacterin 11-34 days earlier into M. longissimus lumborum. The bacterin was composed of inactivated Escherichia coli and Campylobacter fetus ssp. venerealis in a proprietary adjuvant. Tissues were collected for histopathology from 9 affected cattle that died or were euthanized after clinical signs lasting 6-38 days. A range of tissues, including the injection site lesion and lumbar spinal nerve roots, was obtained for ultrastructural examination from a cow with paresis of 31 days duration. There was locally extensive pyogranulomatous myositis with fibrosis and necrosis in right M. longissimus lumborum. Extension of the lesion into the vertebral canal via spinal nerve foramina resulted in focal pyogranulomatous inflammation in epidural fat and in adjacent dura mater. There was axonal degeneration in dorsal, lateral, and ventral columns and chromatolysis of spinal motor neurons in lumbar spinal cord, secondary to compression. A distinctive histologic and ultrastructural feature of pyogranulomata was the presence of osmiophilic material at the center of inflammatory foci, surrounded by macrophages and giant cells that contained intracytoplasmic lipid droplets. Ultrastructural examination of entrapped spinal nerves revealed axonal degeneration and loss of myelinated and unmyelinated fibers, segmental demyelination with remyelination, axonal spheroid formation, and early axonal regeneration.(ABSTRACT TRUNCATED AT 250 WORDS)

We performed a retrospective chart review of 100 patients with idiopathic orbital myositis, who were of ages 9 to 84 years. Data from 75 patients gave the following results. Females were affected more than twice as often as males. Fifty-one patients (68%) had single muscle involvement, with the lateral and medial recti affected most frequently (38 cases [33%] and 33 cases [29%] of muscles, respectively). In 34 patients (45%), affected muscles functioned normally; the remaining 55% (63 muscles) were fairly equally distributed between paretic (20%), restrictive (20%), or combined paretic and restrictive (15%) myopathies. Analysis of muscle function, echographic findings, and duration of symptoms indicates that within days of onset of symptoms, the affected muscle is initially enlarged but retains normal function. Within the first two weeks, continued enlargement results in muscle paresis. The muscle may then enter a partially or completely restrictive phase, which may become permanent. Fifty-one patients (68%) responded well to systemic corticosteroids, although 11 patients (15%) had further recurrences of the disease. Seven patients (9%) later developed thyroid eye disease after initially having unimuscular orbital myositis. We advocate early institution of corticosteroids in order to avoid permanent restrictive myopathies.

In clinical practice herpes zoster infections are common. The cause is the reactivation of the herpes varicella virus that persists in the sensory ganglia after an earlier primary infection with shingles. There are several neurological complications such as meningitis, ventriculitis, encephalitis, myelitis, cerebral angiitis, myositis, paresis of motor nerves, acute polyneuritis, and most commonly post-zoster neuralgia. A proposed reason for these complications is the direct infiltration of the virus or a hematogenous infection. Some of the complications can be treated symptomatically such as post-zoster neuralgia and the occurrence of certain complications that can be prevented by the right choice of acute therapy.
