In a kindred with a familial visceral myopathy, seven patients had operations seeking relief of chronic abdominal pain and other symptoms of intestinal obstruction; one patient had an 80% cystectomy and a Y-V-plasty of the bladder neck for urinary retention. Five patients with megaduodenum had bypass operations; a side-to-side duodenojejunostomy was done in four and a retrocolic gastrojejunostomy in one. Two of these died of postoperative complications, and one developed symptomatic adhesions. Two other patients who had duodenojejunostomy have done well for 6 years and 1 1/2 years respectively. One patient with dilation of the distal jejunum and proximal ileum had relief of intestinal obstructive symptoms from jejunostomy to decompress the destal jejunum. One patient who had a resection of the descending and sigmoid colon for sigmoid volvulus has done well for four years. Three of these seven patients developed peritonitis postoperatively, and two had symptomatic adhesions after operations. Duodenal aspiration from a patient who developed postoperative peritonitis grew E. coli, 10(13) colonies per ml. After review of the results of operations in other families and in our kindred, we favor side-to-side duodenojejunostomy in megaduodenum. Duodenal aspirate must be cultured before operation. Evidence of bacterial overgrowth in the aspirate should prompt appropriate antibiotic treatment to reduce the likelihood of sepsis.

Eleven patients with inoperable brain tumours were treated with high doses of corticosteroids (methylprednisolone 200-2000 mg/day) for up to 151 days (mean 55 days). Neurological improvement occurred in eight patients on high doses after deterioration on concentional doses (methylprednisolone 80-120 mg/day). In two patients steroids could be completely discontinued for several months. Serious adverse effects included sepsis in three patients and myopathy in tow. All three patients with sepsis also received chemotherapy. There were no deaths that could be attributed to steroids. The most likely effect of high dosage steroids is reduction of cerebral oedema. It is conceivable that in some instances high dose steroids may also result in tumour inhibition or oncolysis or both.

We describe three patients who required mechanical ventilation for severe acute exacerbations of obstructive airways disease. When treatment with sedatives and muscle relaxants was withdrawn, they exhibited profound generalized weakness and consequently required prolonged ventilation despite resolution of the airway obstruction. Clinical features were variable, but none of the patients developed failure of other organs and infection was confined to the lungs. All had electrophysiologic evidence of a predominantly motor axonal syndrome. One patient in whom sensory action potentials were abnormal may represent an unusually severe case of critical illness neuropathy occurring in the absence of systemic sepsis and multiple organ failure. In the other two cases, this diagnosis is made less likely by the complete absence of sensory involvement and in these patients the lesion appeared to be either in the most distal portion of the motor neuron or at the neuromuscular junction. In all three patients, resolution was slow but eventually complete. The etiology of the condition is not clear, but it seems to be distinct from the acute myopathy previously described in asthmatics who had received mechanical ventilation. It is important to recognize this phenomenon to avoid erroneous conclusions about the likelihood of the patient recovering from ventilator dependence. A prolonged weaning period is to be expected in such cases.

Up to now, 71 critically ill patients have been reported with neuromuscular complications after artificial respiration. The authors review the literature and present data of a personal series of 22 patients all suffering from severe flaccid tetraparesis and muscle atrophy, which developed after an average of two weeks artificial respiration. The prognosis was relatively good in those surviving the primary disease. The multiconditional causes are discussed with emphasis on the combination of polyneuropathy and myopathy. Tumor necrosis factor (TNF), a key mediator of sepsis, which also has an influence on muscle and nerves, is mentioned as a possible cause of this illness.

Skeletal muscle wasting is commonly observed in critically-ill patients and has been attributed to catabolic fibre atrophy and to neuropathy. This study describes the occurrence of a necrotizing myopathy in 15 out of 31 critically-ill patients who had percutaneous biopsies taken from the tibialis anterior muscles. While most cases showed necrosis of isolated fibres, 5 of the 12 patients who had serial biopsies showed progressive necrosis of up to 95 per cent of the fibres. One other case showed infarction and one case had staphylococcal vasculitis. Atrophy of type 1 and/or type 2 fibres was documented by morphometry in 12 cases. Myoglobin-containing casts were demonstrated immunohistochemically in renal tubules on either biopsy or necropsy material in 5 out of 7 cases. The presence of muscle necrosis was a clinically unexpected finding which may contribute to weakness, complicate the interpretation of tissue biochemistry and energy balance studies, and potentiate renal failure. The necrosis is probably multifactorial in origin, with ischaemia and sepsis contributing factors.

A 36-year-old patient developed marked pigmentation, marked myopathy and severe hypokalaemic alkalosis which at first pointed towards an ectopic ACTH syndrome. The dexamethasone test at a high dose indicated cortisol suppression. A mediastinal tumour was seen radiologically, but the sella was of normal size. Computed tomography provided indirect signs of a sellar space-occupying lesion which suggested an ectopic production of corticotropin-releasing factor (CRF) as cause of the Cushing's syndrome. CRF concentration in antecubital venous blood was markedly elevated to 280 ng/l. The mediastinal tumour was excised and proved to be a carcinoid histologically. Postoperatively the CRF concentration fell to 70 ng/l. An extract of the carcinoid contained 15.5 ng/g wet-weight of CRF and 254 ng/g wet-weight of beta-endorphin. The patient died 5 weeks postoperatively of sepsis with bilateral pneumonia. At autopsy the hypophysis was of normal size but showed nodular ACTH-cell hyperplasia. This was thus a case of Cushing's syndrome resulting from ectopic CRF production in a mediastinal carcinoid tumour.

Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS), a visceral myopathy causing intestinal obstruction in the newborn, is a generally fatal condition, with death being secondary either to sepsis or to malnutrition if long-term intravenous feeding is not provided. A patient with MMIHS is described who has been raised by total parenteral nutrition (TPN) for seven years since her birth. Severe hepatic dysfunction was encountered in early infancy, which gradually cleared after the initiation of milk feeding by mouth, although the milk could not be absorbed because of the high-output jejunostomy. The patient also experienced a bone disease similar to scurvy but caused by copper deficiency at the age of 9 months. The central venous catheter now in situ is the 25th one for the patient. When these catheters were evaluated, the Broviac proved more efficacious than the traditional Silastic for use in long-term TPN. The patient does not yet have normal bowel function and still requires TPN.

Scleromyxedema is a rare fibromucinous connective tissue disorder characterized by papular skin lesions associated with sclerosis and a serum monoclonal gammopathy. Little is known about either the natural history or the systemic manifestations of this disease. We reviewed the medical records of 19 patients with biopsy-proven scleromyxedema seen from 1950 to 1985 for evidence of systemic disease. There were 10 males and 9 females with a median age at diagnosis of 53 years. Monoclonal gammopathy was present in 13 patients. Eight patients complained of dysphagia; 3 had proximal esophageal dysfunction and 1 had total esophageal aperistalsis on barium swallow. Proximal muscle weakness was noted in 5, with an inflammatory myopathy in 3. Six patients complained of dyspnea on exertion. Of these, 5 had reduced diffusing capacity, 3 had reduced volumes, and 2 developed cor pulmonale. Pathologic changes characteristic of "scleroderma kidney" were demonstrated in 1 patient at postmortem. One patient had Raynaud's phenomenon and 2 had arthralgias/arthritis with noninflammatory synovial fluids. Although 8 of 12 patients treated with melphalan noted regression of their skin changes, no consistent improvement in the extracutaneous manifestations was demonstrated. Furthermore, 2 patients died of sepsis related to melphalan-induced myelosuppression, and 4 developed hematological malignancies following melphalan therapy. In conclusion, systemic manifestations in scleromyxedema are more prevalent than previously recognized, and can resemble those of scleroderma. Significant toxicity occurred with the use of alkylating agents in these patients, with treatment-related complications developing in 45% of patients treated with melphalan. The lack of definitive data regarding the natural history of this disease complicates the question of optimal therapy, but the use of alkylating agents should be reserved for those patients with severe debilitating skin disease.

Sepsis and critical illness occur as complications of illness, injury, or surgery in approximately 5% of patients in our critical care unit. Clinical evaluation of the nervous system is difficult in this clinical setting, and electrophysiologic studies are therefore quite valuable. Electroencephalography detects encephalopathy and electromyography (EMG) and nerve conduction studies detect neuromuscular disorders at early stages of their development. Thus, septic encephalopathy occurs in almost all patients and critically ill polyneuropathy in at least 50% of such patients. The polyneuropathy is a predominantly distal axonal degeneration of motor and sensory fibers. A catabolic myopathy is also present, but is difficult to detect electrophysiologically. No defect in neuromuscular transmission has so far been demonstrated. Both the encephalopathy and polyneuropathy may be quite severe, but with vigorous management of the sepsis and critical illness complete recovery may occur in the 40% of patients who survive.

An X-linked recessive disease is reported in a large pedigree. The disease is characterised by a triad of dilated cardiomyopathy, neutropenia and skeletal myopathy. The untreated patients, all boys, died in infancy or early childhood from septicemia or cardiac decompensation. Ultrastructural abnormalities were observed in mitochondria in cardiac muscle cells, neutrophil bone marrow cells and to a lesser extent (0-9%) in skeletal muscle cells. Membrane-bound vacuoles were seen in neutrophil bone marrow cells. Intramuscular fat droplets were increased in type I skeletal muscle fibres. An affected patient had intermittent lactic acidemia, borderline low plasma carnitine, the latter decreasing during periods of illness, and low muscle carnitine (27% pretreatment; 35-40% posttreatment). While on treatment with oral carnitine he had less weakness and no cardiac complaints, but his neutropenia was not affected. Respiratory chain abnormalities were observed in this patient's isolated skeletal muscle mitochondria. These were: (1) diminished concentrations of cytochromes c1 + c, b and aa3 to 29, 47 and 64% of the averaged controls, and (2) a lowered P:0 ratio for oxidation of ascorbate + TMPD, with diminished uncoupler stimulated Mg2+-ATPase activity. Muscle AMP deaminase was deficient (5 resp. 17%). Only one previous report (Neustein et al. 1979) on X-linked mitochondrial cardiomyopathy exists, which probably refers to the same entity. Biochemical studies and haematological abnormalities (neutropenia) are reported for the first time.
