We report two cases of axonal sensori-motor polyneuropathies complicating sepsis and multiple organ failure (MOF) among severely burned patients (total burned surface area of 35 to 40 per cent) in which no other cause of neuropathy was retrospectively identified. No steroids or neuromuscular blocking agents had been given. The date of onset was not established but the diagnosis was late, between the 30th and 45th day, at the recovery of consciousness. Regression was incomplete, with severe sequellae especially in one patient who was unable to walk 10 months after the injury. Burned patients can present with many kinds of peripheral neuropathies. Postburn polyneuropathies with nerve conduction slowing were described by Henderson. Mononeuropathies can result from nerve compression complicating unfavorable postures in comatose patients or from nerve entrapment in ischemic limbs. Polyneuropathy in postburn sepsis with MOF does not appear to have been previously reported. Postburn sepsis usually occurs in young patients, without other cause of MOF; and therefore represents a relatively "pure" sepsis syndrome.

Thirty-four evaluable patients were treated with vinorelbine, a novel, semisynthetic vinca alkaloid, as first-line chemotherapy for advanced breast cancer. They received vinorelbine 25 mg m-2 i.v. given weekly for a maximum of 16 cycles. Two patients achieved a complete remission and 15 a partial remission, giving a response rate of 17/34 (50%; 95% CI of 34-66%); median response duration was 5.8 months. The median progression-free interval was 4.4 months and median survival 9.9 months. Treatment was generally well tolerated. Fatigue was the most common side-effect. The main reason for dose adjustments was myelosuppression; 68% of patients had WHO grade 3 or 4 neutropenia and there was one death attributed to neutropenic sepsis. Nausea/vomiting and neuropathy were mild and alopecia was uncommon. This study confirms vinorelbine as a highly active, well-tolerated agent in advanced breast cancer worthy of evaluation in combination chemotherapy regimens.

Familial visceral neuropathy is a rare cause of chronic intestinal pseudo-obstruction. It is characterized by progressive destruction of the gastrointestinal myenteric plexus resulting in dysmotility and associated early satiety, post-prandial bloating, recurrent nausea and vomiting, abdominal distension, chronic diarrhea, weight loss, and malnutrition. In its varying forms, there may be neuronal destruction in other parts of the peripheral and central nervous system. We report on four siblings who presented in their third or fourth decades with initial clinical features of chronic intestinal pseudo-obstruction and eventual progressive diffuse neuronal disease, characterized by leukoencephalopathy and peripheral neuropathy. Within 5 yr of presentation, all four patients died from inanition and sepsis, despite aggressive nutritional support. Their clinical and pathological features are characteristic of familial visceral neuropathy of the autosomal recessive form. This presentation may represent a unique syndrome characterized by a tetrad of polyneuropathy, ophthalmoplegia, leukoencephalopathy, and intestinal pseudo-obstruction.

Neuropathic complications of the burn patient are frequently undiagnosed. A retrospective study was performed looking at neuropathies in patients admitted to a tertiary care burns centre from 1984 to 1991. Nineteen out of a total of 800 patients had signs and symptoms of neuropathy, confirmed on neurophysiological testing. Most patients were severely burned with 11 patients (69%) having a total burn surface area of > 20%. Twenty-eight percent were full thickness burns. Mononeuritis multiplex was the most common finding in these patients, occurring in 11 (69%). This has not been reported before. Three patients (19%) had an isolated mononeuropathy, one (6%) had a radiculopathy and one had a generalized axonal polyneuropathy. Of the patients with mononeuropathy, nine had lesions only in burned areas and four had lesions in burned and unburned areas. Eleven patients had complications of sepsis with five also having renal failure. Age, sex, serum albumin, magnesium, phosphate, creatinine, the presence of sepsis and the number or type of drug did not correlate with the number of affected nerves nor the extent of recovery. The length of hospitalization and severity of the burns were the only two factors which correlated with the number of affected nerves. Vascular occlusion of the vasa nervorum, direct thermal injury or a disseminated neurotoxin are postulated as possible aetiological mechanisms.

In diabetic patients the foot is the focal point of neurologic, arterial and infectious complications. Affections of the foot are generally synonymous with a diabetic trophic disorder: the risk of gangrene is 17 times greater in diabetics than in non diabetics. Trophic disorders can affect the functional prognosis when they lead to amputation with subsequent altered weight bearing. They can provoke worsening of a subjacent arteriopathy, until then partially or totally asymptomatic, when the excision wound lacks the hemodynamic capacity for healing because of the associated arteriopathy. They can also induce local, regional (cellulitis) or even general (septicemia) infectious complications. They have a major socio-economic effect, by the loss of quality of life, the inability to work, and the cost of hospital and general care they engender. Finally, they have to be experienced by the patient and the treating team as a failure since, in the majority of cases, they imply an insufficient a priori knowledge of the predisposing factors: arteriopathy of legs and neuropathy with loss of sensitivity depriving the patient of the pain alarm signal if cutaneous lesions develop, and a delay in the recognition of triggering factors represented by microtrauma caused by shoes, particularly burns, frostbite or infections.(ABSTRACT TRUNCATED AT 250 WORDS)

Onion bulb formations involving cranial nerves are an unusual pathologic feature. We report the postmortem neuropathologic findings in a 69-year-old man with a longstanding neuropathy characterized by progressive muscle weakness, sensory ataxia and multiple cranial nerve abnormalities. Electrodiagnostic testing disclosed features of an acquired demyelinating polyneuropathy. Treatment with corticosteroids and plasmapheresis resulted in no change in his neurologic status, and the patient died after repeated episodes of pneumonia and sepsis. Autopsy showed widespread onion bulb formation in cranial nerves III, IV, V, VI, X, XI and XII, anterior and posterior spinal nerve roots, dorsal root ganglia and multiple peripheral nerves, some of which also had foci of epineurial perivascular inflammation. Muscle sections revealed severe neurogenic atrophy. This case demonstrates that, in longstanding acquired demyelinating neuropathy, the cranial nerves also undergo repetitive cycles of demyelination and remyelination resulting in severe weakness of the bulbar musculature and histologic features of hypertrophic neuropathy.

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.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a progressive or relapsing immune-mediated neuropathy usually responsive to plasma exchange, intravenous gammaglobulin or steroids, with some patients being refractory to these conventional therapies. We report a patient with CIDP who had spontaneous improvement after an episode of sepsis, but subsequently relapsed with severe generalized weakness; he was unresponsive to the conventional treatments for CIDP but had dramatic improvement following treatment with interferon-alpha 2A. Nerve conduction studies following treatment showed improved distal compound muscle action potential amplitudes without change in the degree of conduction block. The mechanism of action of interferon-alpha is unknown, but it may modulate proinflammatory cytokines that have a role in immune-mediated demyelination. Interferon-alpha may be an effective alternative therapy in patients with CIDP who relapse or are refractory to conventional treatments.

We report 13 patients with pathologically confirmed perineuritis. Seven patients had diabetes mellitus, 5 had nutritional abnormalities, 2 had associated rheumatological illnesses, 2 had sepsis with multiorgan failure, and 1 had a history of malignancy. Electrophysiologic testing demonstrated mononeuritis multiplex in 7, demyelinating neuropathy in 4, distal sensory and motor neuropathy in 1, and polyradiculoneuropathy in 1. Twelve patients received immunomodulating therapy with variable responses. We conclude that perineuritis is associated with a number of different systemic conditions and several clinical patterns of peripheral neuropathy. Response to immunomodulation is variable. The most frequent association is with diabetes mellitus, a previously unrecognized association.

Advanced transitional cell carcinoma (TCC) of the urothelial tract is usually fatal despite high response rates to platinum-based chemotherapy regimens. Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) has demonstrated marked single-agent activity in TCC, and combinations of carboplatin and paclitaxel have been well tolerated in other solid tumors. Methotrexate is also active in TCC. Due to unexpectedly severe myelosuppression and mucositis when methotrexate and paclitaxel were combined, we undertook a phase I trial of paclitaxel, carboplatin, and escalating doses of methotrexate with granulocyte colony-stimulating factor and leucovorin support in advanced TCC to determine the feasibility of this combination. Nineteen previously untreated patients with locally advanced or metastatic TCC were eligible. Median age was 62 years. In sequence, paclitaxel 200 mg/m2 (3-hour infusion), carboplatin dosed to an area under the concentration-time curve of 6 mg/mL x min, and methotrexate 10 mg/m2, increasing in 10-mg/m2 increments, were administered on day 1 every 21 days. Granulocyte colony-stimulating factor 300 microg/d or 480 microg/d (in patients <60 kg or >60 kg, respectively) was administered on days 2 through 11 and leucovorin 15 mg orally every 6 hours for 3 days. At this time, the methotrexate dose has been escalated to 50 mg/m2. There were no dose-limiting toxicities in cycle 1. Sixty-eight cycles have been administered (range, one to eight cycles; median, three cycles). Significant hematologic toxicity including neutropenic sepsis (two episodes) occurred in subsequent cycles, but was infrequent. The major nonhematologic toxicity was neuropathy. Sixteen patients are evaluable for response. One patient has achieved a complete response, seven are partial responders, seven have stable disease, and one progressed on therapy. The overall response rate is 50% (95% confidence interval, 25% to 75%). The combination of paclitaxel, carboplatin, and methotrexate holds promise to be well tolerated and active in advanced TCC.
