An epidemy of fatal posterior weakness was observed in Norwegian dairy goats with a spontaneous character (high fever, collapse, death). Clinical, postmortem, and histopathological findings indicated gastroenteritis, liver damage (necrotic foci), soft kidneys, pneumonia, and depletion of liver glycogen in goats up to 4 months of age. In older animals there was a prevalence of muscle degeneration. Indigenous goats did not exhibit any mortality, whereas the mortality rate in male crosses Norwegian X Tanzanian was 100%, regardless of their age. In young goats, the existence of a high mortality infectious syndrome with enterotoxaemia and fever is suspected, whereas older goats were probably exposed to a non-infectious myodegeneration.

A 55-year-old, malignant hyperthermia-susceptible patient underwent myocardial revascularization without incident. Six hours postoperatively, he developed what was initially diagnosed as an MH crisis, for which he received intravenous dantrolene. The resultant muscle weakness prolonged the duration of postoperative mechanical ventilation and likely contributed to the development of a postoperative pneumonia. Plasma dantrolene levels were measured for the first 48 hours postoperatively and correlated with clinical findings. On reviewing the patient's perioperative course, it was felt that the hypermetabolic state was not due to MH. The patient's pattern of rewarming following hypothermic cardiopulmonary bypass was similar to non-MH-susceptible patients. Because of the difficulty in diagnosing a MH crisis after hypothermic bypass, it is recommended that patients receive prophylactic dantrolene preoperatively and after bypass. Nondepolarizing muscle relaxants should be given postoperatively to prevent shivering and respiratory acidosis while patients rewarm.

A new patient with Leigh's syndrome (subacute necrotizing encephalomyelopathy due to pyruvate dehydrogenase complex deficiency) is presented. A Turkish boy of consanguinously married healthy parents developed progressive muscle weakness since infancy. At the age of 3 years he was unable to sit, stand or walk. Clinical examination showed general muscle weakness, hypotonia, muscle hypotrophy, bilateral ptosis, partial bilateral external ophthalmoplegia, nystagmus, intention tremor and hypoactive tendon reflexes. The EEG showed diffuse slowing, the cerebral CT scan disclosed mild hydrocephalus e vacuo. Motor nerve conduction velocity was slightly decreased, the EMG revealed signs of neuropathy. In the biopsied muscle only a mild hypotrophy of type 2 fibres was found, no abnormal mitochondria could be detected. The sural nerve was slightly abnormal: loss of large myelinated axons, loss of unmyelinated nerves. CSF protein was elevated to 80 mg/dl, protein electrophoresis revealed the pattern of markedly impaired blood-CSF barrier. Serum lactate and pyruvate were permanently elevated. In the urine the excretion of alanine was raised. The clinical state deteriorated during intercurrent infections; somnolence, vomiting and Cheyne-Stoke's respiration occurred. At the age of 3 1/2 years the child died of pneumonia. In the liver tissue a decreased activity of the pyruvate dehydrogenase complex was found. Neuropathological examination of the brain demonstrated wide-spread changes of Leigh's spongiform encephalopathy. Several enzyme deficiencies have hitherto been associated with Leigh's syndrome: This patients confirms earlier findings that a subgroup of Leigh's syndrome is caused by pyruvate dehydrogenase complex deficiency.

Gram-negative neonatal septicemia was diagnosed in a premature Standardbred colt. Clinical signs included lethargy, weakness, loss of suckle reflex, tachypnea, and injected mucous membranes. Sequelae included pneumonia, omphalophlebitis, septic arthritis, and osteomyelitis. Prepartum maternal uterine infection, premature delivery, abnormal parturition with premature fetal membrane separation, and failure of passive transfer of colostral immunoglobulins increased the foal's risk for developing sepsis. Treatment included administration of moxalactam disodium and cefadroxil. The clinical efficacy of cephalosporin antibiotics in the treatment of gram-negative sepsis is discussed.

The clinical and laboratory features of moderate to severe organophosphate and carbamate toxicity in 37 infants and children are presented. Ingestion of an improperly stored liquid pesticide was the most common route of intoxication (76% of patients); five (14%) children became intoxicated after playing on carpets and floors of homes that had been sprayed or fogged by unlicensed exterminators. The transfer diagnoses were incorrect for 16 or 20 patients who were transferred to our center from another institution. Miosis (73%), excessive salivation (70%), muscle weakness (68%), and lethargy (54%) were the most common abnormal signs; 49% and 22% of patients had tachycardia and seizures, respectively, and 38% of children had respiratory insufficiency that required endotracheal intubation and mechanical ventilation. The results of erythrocyte and serum cholinesterase activity assays were concordant in 83% of patients. Thirty-four (92%) patients were treated with atropine and/or pralidoxime; three patients required only supportive care. Most patients had a prompt response to therapy; however, two patients with organophosphate toxicity required multiple doses of atropine during a 24-hour period; in both instances, the doses of atropine were subtherapeutic. There were no deaths. Pneumonitis and/or atelectasis developed in ten patients, including six who had ingested a petroleum distillate-containing insecticide.

Adult-onset Still's disease is characterized by seronegative arthritis, fever, and an evanescent skin rash. Earlier reports have described pneumonitis and pleuritis as manifestations of this disease. We report a patient with adult-onset Still's disease with severe restrictive ventilatory impairment and evidence of respiratory muscle weakness who responded to corticosteroid and aspirin therapy.

A 38 year-old wife, of belgian origin and residency, suffered from a left retrobulbar optic neuritis in 1973, with as only sequel dyschromatopsia and central scotoma enlargement. In 1985, 12 years later, she complained of a progressive weakness of the right hand, and developed a spastic tetraplegia within four months. The C.T. Scan showed white matter hypodensities, without mass effect or contrast enhancement, first limited to the left centrum semiovale and later on with multifocal character. Somatosensory evoked potentials after stimulation of the right median nerve demonstrated only lemniscus medialis response. Multiple sclerosis was initially suspected. Analysis of lymphocytes subsets however showed a markedly reduced helper population with as a result a very low H/S ratio, and the serology was found positive for HTLV-III-LAV, thus demonstrating the diagnosis of acquired immune deficiency syndrome (AIDS). Visceral autopsy demonstrated only a CMV pneumonia. Autopsy of the brain showed typical lesions of progressive multifocal leukoencephalopathy (PML). This case is compared with 20 previously published observations of PML associated with AIDS and appears rather unusual due to the association of unfrequent clinical peculiarities: previous, probably coincidental, retrobulbar optic neuritis, female patient, lack of risk factor and clinical symptoms of AIDS. The diagnostic difficulties in the present case are emphasized.

An autopsied case of Pick's disease, having an extraordinary cerebral change in the anterior portion of Lobus frontalis and temporalis, was reported. Our case is a 71 year-old woman at death with a fourteen year history of chronic progressive dementia and mental deterioration, and it may be stressed that the existence lasted 8 years, over the latter half of clinical course, was depended on the tube feeding. The first symptoms suddenly appeared in 1964, 2 months after her husband's death of illness, when she was 57. She prepared the table for breakfast late at night, calculated wrongly in her domestic account book, and stole foods in the grocery. Two years later, her illness was diagnosed as presenile dementia by characteristic personality change and marked dilatation of anterior horn of lateral ventriculus. On admission to National Musashi Sanatorium, three years after the first symptoms' appearance, she presented restless walking, insomnia, memory loss, weakness of concentration, and high degree of disorientation. Particularly, it was noticeable that she behaved with bizzare contact. After 1970, tube feeding was introduced continuously, because of swallowing difficulty. Death occurred in July 1978 from a general weakness and a broncho-pneumonia, 14 years after the onset of the first symptoms. Autopsy revealed small and atrophied brain weighed 820 g. Cerebral cortical atrophy extended to frontal, temporal, insular, and parietal lobes, but right T-1 was relatively well preserved. On section, frontal and temporal ventriculus were remarkably enlarged and caudate nuclei were extremely atrophic.(ABSTRACT TRUNCATED AT 250 WORDS)

The preleukemic syndrome occurs mainly after middle age. We report 11 patients, aged 62 to 92 years, who presented with weakness, fatigue, malaise and pallor. Eight patients died; survival from the time of diagnosis was between 2 and 21 months. Two of them developed acute myelomonocytic leukemia. A third patient developed Philadelphia chromosome-negative chronic myeloid leukemia within 9 months. Serum unsaturated B12 binding capacity and transcobalamin I were elevated in this patient, preceding the transformation to chronic myeloid leukemia. Five other patients died from sepsis or pneumonia. All patients were anemic, and 10 were leukopenic. Bone marrow was hypocellular in 1 and hypercellular in 10 cases. Chromosomal studies were performed in five patients, with three showing abnormal findings: 47xx, trisomy 8 and a tetraploid karyotype 92xxyy5q-. No cytotoxic treatment should be given during the preleukemic phase until transformation to acute leukemia occurs. Since preleukemic patients are very susceptible to infections, early diagnosis of the condition is important, as is supportive care in the case of surgery.

Correct identification of the subsets of pulmonary lupus has an unquestioned importance in planning the proper therapeutic regimen in this extremely variegated disease. Asymptomatic pulmonary lupus needs no treatment; however, pulmonary involvement in lupus may be life threatening, in which case prompt and aggressive treatment is mandatory. The different aspects of pulmonary lupus are demonstrated through the clinical histories of patients who suffered from pleuro-pulmonary lupus. The following entities are presented: lupus pneumonitis, lymphocytic interstitial pneumonia, pulmonary hypertension, pulmonary hemorrhage, pulmonary embolism associated with circulating lupus anticoagulant, lupus pleuritis and weakness of the diaphragm.
