Pulse volume recording disturbances in paraplegic patients.

Spinal cord injuries may modify vascular reactivity in the denervated region. This study presents an original observation of altered vascular response in paraplegic patients. A group of 30 consecutive paraplegic otherwise normal individuals underwent a thorough vascular examination. There were 29 male and 1 female patient, 21 to 67 years old (average 41), all with traumatic spinal cord injury. Average time since injury was 17 years. All had good peripheral pulses and normal segmental Doppler pressure measurements. In 8 patients, plethysmography--pulse volume recording (PVR) was normal as expected. In 22 patients an unusual feature of the vascular examination was recorded, consisting of normal peripheral arterial pressures with PVR waveforms indicating poor pulsatility. This group was older than the group with normal studies: ages 44 +/- 13 vs 34 +/- 8 years (p = 0.05), and more time had elapsed since injury-20 +/- 12 vs 10 +/- 4 years (p = 0.015). The altered pulsatility demonstrated in most of those paraplegic patients may play a role in deficient wound healing frequently observed below the level of spinal neurological loss.

[Stroke in the young].

31 young patients who were hospitalized and rehabilitated after acute cerebral stroke, we are reassessed. In 58% there was a wide array of underlying diseases and risk factors, while in the others the cause could not be established. 74% suffered from nonhemorrhagic, thrombotic or embolic phenomena and 25% from intracerebral or subarachnoid hemorrhage. There were no alarming preceding signs. After an average of 31 months following the cerebrovascular accident, more than 90% were independent in all daily living activities. Functional outcome did not depend on the underlying disorder.

The 'hyperprosexia phenomenon' in traumatic brain injured patients (a forgotten term for an old problem).

In traumatic brain injured patients the basic functions of the cognitive, behavioral, emotional and intellectual systems are disturbed. The patients' ability to regulate the interaction between the ego and the external world is diminished and they present inflexible, concrete and sometimes inappropriate behavior. We have not observed anosognostic phenomena in these patients. Most of them are preoccupied with their physical impairments and unaware of their intellectual deficits. We hypothesize that this preoccupation or 'hyperprosexia phenomenon' may be observed in traumatic brain injured patients. The various neuropsychological, medical and philological aspects of these terms are discussed.

Arm crank ergometry in chronic spinal cord injured patients.

Cardiovascular response to arm crank ergometry, using a specially adapted Monark bicycle ergometer, was examined in 98 men with long-standing spinal cord injuries (SCI), who were classified into groups by neurologic level of SCI. Exercise response was significantly correlated with lesion levels: the higher the lesion, the lower the levels of physical work capacity and mean exercise systolic and diastolic blood pressure. Also, physical symptoms and abnormal systolic blood pressure exercise response were more frequent. Exercise response of patients with lower thoracic and lumbar SCI did not differ from the control group. The undisputed value of ergometry in the routine evaluation and exercise prescription for health maintenance in SCI and other wheelchair-disabled patients was substantiated by the study findings.

Upper limb functions regained in quadriplegia: a hybrid computerized neuromuscular stimulation system.

A new, computerized neuromuscular stimulation system was applied to the upper limbs of two patients with complete quadriplegia below the C4 level. The stimulation-generated movements were integrated and augmented by residual, voluntary shoulder girdle movements and mechanical splinting. Up to 12 muscles were stimulated individually with high-resolution surface electrodes; coordination and control of the stimulation was effected by microcomputer. Simple vocal commands to the computer triggered preprogrammed hand prehensions, arm motion, and other functions, giving the patient complete control over the system. In pilot clinical trials of six weeks, writing, eating, and drinking, including picking up and replacing the pen or cup, were achieved.

The 'evening syndrome'--a sign of failure in providing sufficient geriatric amenities.

Emergency wards are under pressure most of the hours of the day and night. When patients arrive during the working hours of outpatient clinics it is possible to divert some of them. Once the clinics are closed, all patients that arrive at the casualty department are examined. Families that have elderly disabled persons at home often then bring the disabled to the emergency ward on some pretext of acute distress and then disappear, leaving the elderly person in the care of the hospital. The responsibility of providing sufficient geriatric institutions rests with departments of health, municipalities, and medical aid societies. Until such provision is made, hospitals will remain overcrowded with people who only require good auxiliary nursing care.

Spinal cord injury associated with blunt traumatic rupture of the diaphragm.

The incidence of spinal cord injury associated with blunt traumatic rupture of the diaphragm is extremely low and rarely mentioned in the numerous reports about rupture of the diaphragm. It is thought that more such cases can be found among the fatalities of aircraft accidents and presumably among the fatalities of road traffic accidents as the forces causing such injuries make it unlikely for the casualty to survive. The authors present six cases encountered at Stoke Mandeville Hospital, England, and at Sheba Medical Centre, Israel. Although the mortality of such cases, if the patient survives the original impact, is usually due to associated injuries, early diagnosis is essential as late complications increase the incidence of delayed mortality.

Acute transverse myelitis, a possible vascular etiology.

Seven acute transverse myelitis patients are presented, in whom the course of illness suggests a vascular pathogenesis. In the absence of predisposing risk factors for vascular accidents and such systemic symptoms as occur frequently in vasculitic syndromes, association in hypothesized with isolated angiitis of the central nervous system. Combined treatment with corticosteroids and cyclophosphamide is, therefore, suggested for severe cases of acute transverse myelitis, in whom no etiology can be found.

'Duplicate limbs' sensation in acute traumatic quadriplegia.

A 64-year-old man sustained acute quadriplegia due to a traffic accident, while in the midst of a petit mal seizure. After recovery from the initial medical complications he developed a duplicate limb phenomenon. The patient felt that another pair of upper and lower limbs had grown from his body, parallel to the paralysed limbs. To the best of our knowledge this duplicate phenomenon in all limbs has not been described before in a traumatic quadriplegic patient. It is our impression that this phenomenon is a rare example of preoccupation with the paralytic limbs, of sensory deprivation with a (possible) unusual drug reaction.
