In the past 10 years, the diagnosis of pseudoobstruction lasting more than two months was confirmed in 10 infants after sepsis, meconium ileus, and Hirschsprung's disease were excluded, and surgery or autopsy failed to demonstrate a site of mechanical intestinal obstruction. Four infants had undergone prior operation for another anomaly: gastroschisis (2) and ileal atresia (2). Five of the remaining infants also had megacystis. The lack of coordinated intestinal motility was best appreciated by radiocontrast small bowel studies, which showed degrees of aperistalsis or segmentation. Rectal manometric studies were not helpful. Histology of the intestine was normal in seven, while a gross deficiency of nerve fibres was noted in one patient and a myopathy of smooth muscle in another. A variety of drugs used to stimulate peristalsis were ineffective. Seven patients had 25 operations, often to exclude mechanical causes of obstruction. The mainstay of treatment was TPN and intestinal decompression. Six children survived; their ages ranged between 8 months and 9 years (median age, 16 months). There has been improvement in intestinal peristalsis in five children, three of whom now tolerate a regular diet and two of whom are on TPN and are currently increasing oral intake. Four infants died, two from sepsis, two from TPN-related hepatic failure. In contrast to previous reports, we conclude that intestinal pseudoobstruction may be self-limited in some neonates, including those with megacystis. Therapy should consist of long-term nutritional support and treatment of other anomalies that may be present.

Sepsis occurs frequently in the pediatric intensive care unit and is a significant cause of morbidity and mortality. Multiple organ systems are adversely affected by sepsis. Approximately 70% of adult patients with sepsis have peripheral nervous system dysfunction on electrophysiologic studies, of whom 30% are symptomatic. Neuromuscular dysfunction in children with sepsis is increasingly reported; however, the incidence remains undefined. Flaccid quadriplegia with the inability to wean from ventilatory support despite full cardiopulmonary recovery is the typical presentation. However, lesser degrees of weakness may be demonstrated with careful evaluation. Electrophysiologic studies often demonstrate the presence of axonal polyneuropathies, abnormalities of neuromuscular transmission, or acute myopathies. Identifiable neuromuscular syndromes in children with sepsis include critical illness polyneuropathy, pure motor polyneuropathy, thick-filament myopathy, and necrotizing myopathy. The common underlying pathogenic process in these syndromes appears to be sepsis, which may be accentuated by the administration of steroids or neuromuscular blocking agents. Recovery in strength usually occurs over a period of weeks to months.

Trauma and non-traumatic insults can cause muscle damage to such an extent that serious sequelae to other organs may result. Myoglobinuria and subsequent acute renal failure (ARF) is a well known and widely studied fact of such sequelae. Twelve cases of ARF (between 1990-1993) who have developed renal dysfunction after prolonged muscular exercise e.g., squat jumping, sit-ups and blunt trauma from sticks or leather belts mainly given by law enforcing personnel for certain issues were studied. None of them had previous history of myopathy, neuropathy or renal disease. All were critically ill on presentation and required renal support in the form of dialysis. Although morbidity was high in all, eleven of them recovered and one expired due to sepsis.

We describe a 41-year-old patient with adult-onset dermatomyositis who developed persistent pneumomediastinum and severe subcutaneous emphysema due to end-stage interstitial lung disease. The diagnosis of dermatomyositis was based on proximal muscle weakness, electromyographic findings of inflammatory myopathy, and positive findings on muscle biopsy. Low levels of creatine kinase elevation were found at the time of diagnosis (a form of dermatomyositis which has been associated with a poor prognosis). The patient had no signs of cutaneous vasculitis. Despite treatment with prednisone and azathioprine, she died of intercurrent gram-negative sepsis 15 months after the diagnosis of dermatomyositis.

Sepsis and multiple organ failure are major problems in medical and surgical intensive care units. Critical illness polyneuropathy occurs in 70% of these patients. Difficulty in weaning from the ventilator is an early sign. Electrophysiological studies are necessary to establish the diagnosis; these studies show an axonal degeneration of peripheral nerve fibres. Recovery occurs in weeks or months, depending upon severity. Muscle biopsy reveals denervation atrophy. Sepsis itself does not induce a neuromuscular transmission defect, but neuromuscular blocking agents may increase the severity of critical illness polyneuropathy. If steroids are used in addition to neuromuscular blocking agents, a severe myopathy may result. Other effects on muscle are cachectic myopathy and panfascicular muscle fibre necrosis. A variety of combinations of these conditions may affect the same patient. Only well-designed prospective studies will determine the true effect of these medications on the neuromuscular system in septic patients.

Four septic patients and one asthmatic patient are described who developed a severe paralytic disorder in an intensive care unit (ICU), associated with a rise in serum creatine kinase and a severe necrotizing myopathy. All cases had received non-depolarizing muscle blocking agents and large intravenous doses of glucocorticoids. Three patients developed myoglobinuria. No improvement or very little improvement in muscle function was noted in the four fatal cases. The single survivor recovered his strength after 6 months. This syndrome ("necrotizing myopathy of intensive care") provides one of the differential diagnoses for ICU-acquired weakness. The myopathy appears to have several interdependent causes and it is proposed that these should be classified as myonecrosis "priming" factors (glucocorticoids, myotropic infections, sepsis) and "triggering" factors (non-depolarizing muscle blocking agents).

A review was conducted of 236 postmortem examinations of six species of captive and imported bustards in the United Arab Emirates for the period 1979-94. The most common causes of death in adult imported houbara bustards (Chlamydotis undulata macqueenii) were euthanasia due to Newcastle disease, aspergillosis, and post-transportation-related deaths. Helminth parasites were a common finding in imported houbara bustards, and large parasite burdens occasionally caused intestinal obstruction and death. The most common causes of death in adult captive houbara bustards were trauma-related deaths and euthanasia for or death following treatment for capture myopathy. Fatty liver change was an important postmortem finding of captive adult houbara bustards. The main cause of death in juvenile houbara bustards was yolk-sac infection and septicemia. The most common causes of death in adult kori bustards (Ardeotis kori) were capture myopathy and handling injuries or euthanasia following these injuries. The most common causes of death in adult rufouscrested bustards (Eupodotis ruficrista) were post-transportation deaths in imported birds and trichomoniasis and trauma in captive birds. Juvenile rufous-crested bustards appeared to be highly susceptible to gizzard impactions and foreign-body obstructions of the gastrointestinal tract. Nutritional bone disease is an important disease of all juvenile bustards, particularly kori and houbara bustards. Aspergillosis was also a common postmortem finding in captive and imported adult houbara bustards and also caused mortality in juvenile kori and houbara bustards.

An acute myopathy of intensive care occurs in critically ill patients treated with intravenous corticosteroids and neuromuscular junction-blocking agents. The full clinicopathological spectrum is uncertain. We evaluated the clinical, electrodiagnostic, and histopathological features of 14 patients who developed acute myopathy of intensive care after organ transplantation or during treatment of severe pulmonary disorders and sepsis. Patients received high-dose intravenous corticosteroids, usually in conjunction with relatively low to moderate doses of neuromuscular junction-blocking agents. After discontinuation of the latter drugs, most had diffuse, flaccid weakness with failure to wean from mechanical ventilation. Electrodiagnostic findings were consistent with a necrotizing myopathy. Muscle histopathology revealed myopathy with loss of thick filaments in 79%, mild myopathic changes in 14%, and atrophy of type 1 and type 2 fibers in 7%. Loss of thick filaments was identified in muscle biopsy specimens obtained 30 +/- 11 days (mean +/- standard deviation) after intravenous corticosteroid treatment but not in those obtained earlier (12 +/- 2 days). Critically ill patients, including those receiving organ transplants, may develop acute myopathy of intensive care after exposure to intravenous corticosteroids and neuromuscular junction-blocking agents, although the exposure to the latter drugs may be minimal. Selective loss of thick filaments is common in acute myopathy of intensive care, especially if the muscle biopsy specimen is obtained 2 weeks or more after intravenous corticosteroid exposure.

Between 1990 and 1993, we studied 14 cases of acute renal failure due to prolonged muscular exercise (e.g., squat jumping, sit-ups) and blunt trauma inflicted by law enforcement personnel using sticks or leather belts. None of the patients had a prior history of myopathy, neuropathy, or renal disease. All were critically ill and required renal support in the form of dialysis. Although the morbidity was high, 13 of the patients recovered normal renal function. One patient expired due to sepsis.

A 21 year old male ingested podophyllin in a suicide attempt. The disorder was marked by seizures, coma, peripheral neuropathy, renal failure and acute necrotizing myopathy, an unusual finding. The coma and systemic disturbances resolved within three weeks. The myopathy resolved in 7 weeks, demonstrating a high capacity of muscle recuperation. The sensorimotor peripheral neuropathy persisted until the patient's death 9 weeks after the ingestion, due to septicemia. This report confirms the transient central neurotoxicity of podophyllin and persistent peripheral neurotoxicity of podophyllin, and describes a reversible necrotizing myopathy associated to mitochondrial abnormalities, a still unreported feature of podophyllin toxicity.
