Ten hemiparetic subjects underwent functional cardiac stress testing on a supine bicycle ergometer. Their heart rate (HR), blood pressure (BP), and rate pressure product (RPP) were determined at rest and at incremental workloads. Three subjects with no previous history of coronary artery disease (CAD) had positive test results diagnostic or suggestive of CAD. None of the three subjects with a history of myocardial infarction displayed any ECG abnormalities during the exercise. The RPPs obtained during testing were compared to those recorded during various rehabilitation activities. As some difficulties arose in the performance and interpretation of the stress test in patients receiving beta-blocking medication and others with arthritis, spasticity, and orthopedic problems, procedures for handling these problems needed review. The supine bicycle proved to be an appropriate device for cardiac stress testing in a hemiparetic population.

Results of surgical treatment of kyphoscoliosis complicated with spinal cord injury are presented. There were 16 congenital kyphoscoliosis, 5 idiopathic ones and 4 in course of neurofibromatosis. Increased spasticity was present in 2 patients, spastic paresis in 12 and 11 patients were paraplegic. In 24 cases spinal decompression was performed, in 6 years old boy with spasticity the convex side of the curve was fused. Neurological symptoms ceased in 13 cases, marked improvement was achieved in 6 patients, partial recovery in 1 case, in 5 cases no improvement was accomplished. One patient died 6 weeks after operation due to heart attack. Analysis of results achieved indicates, that surgery in most of kyphoscoliosis complicated with spinal cord injury offers good prognosis.

A 70-year-old patient with a history of hypertension and hypercholesterolemia was referred for evaluation of necrotic toes. The patient had a history of several cerebrovascular accidents during the previous month. Initially, she developed sudden-onset left upper extremity weakness which, over the ensuing 4 days, progressed to complete left-sided weakness. This was followed by the development of acute dysarthria. A transesophageal echocardiogram revealed moderate left ventricular hypertrophy, several vegetations on her tri-leaflet aortic valve associated with moderate aortic regurgitation, and a large right atrial thrombus with a mobile component. Bubble studies failed to reveal any septal defects. The patient's electrocardiogram was nonspecific. As serial blood cultures were negative despite fevers of up to 39.8 degrees C, the patient was treated with a 6-week course of intravenous ceftriaxone, ampicillin, gentamicin, and ciprofloxacin for a presumed diagnosis of culture-negative endocarditis. Fungal cultures of the blood were negative. The patient, however, progressed and developed several necrotic toes. Physical examination was significant for ischemic changes of the left first, second, third, and fifth toes, as well as the right first and second toes. Diffuse subungual splinter hemorrhages in the toenails, numerous 2-4-mm palpable purpuric papules on the lower extremities, and nontender hemorrhagic lesions of the soles were also noted. Peripheral and carotid pulses were intact and no carotid bruits were heard. Cardiopulmonary and abdominal examinations were unremarkable. Neurologic examination revealed a disoriented, dysarthric patient with left central facial nerve paralysis, as well as spasticity, hyperactive reflexes, and diminished strength and sensation in the left upper and lower extremities. A left visual field defect and left hemineglect were also present. The patient's last brain computerized tomogram revealed areas of low attenuation consistent with cerebral infarctions in three distinct areas of the brain. These included the left occipitotemporal area, the right parieto-occipital area, and the right posterior frontal region. The regions affected were in the distribution of both the anterior and posterior circulation. No evidence of hemorrhage was noted. The patient subsequently complained of abdominal discomfort. A computerized tomogram of the abdomen with oral and intravenous contrast revealed a 4-cm x 3-cm irregular mass in the tail of the pancreas with several low-attenuation lesions throughout the liver which were consistent with infarctions or metastases. Several splenic infarctions were also present. A biopsy of the tumor revealed pancreatic adenocarcinoma. The patient's carcinoembryonic antigen level was 18. 4 ng/mL (0-3) and the CA 19-9 antigen level was 207,000 U/mL (0-36). The alpha-fetoprotein level was normal. Other significant laboratory findings included a prothrombin time of 16.7 (international normalized ratio, 1.4), an activated partial thromboplastin time of 32 (ratio, 1.3), and a platelet count of 85,000/mm3. The Russell viper venom time, sedimentation rate, and C3 levels were normal, and the patient was negative for antinuclear antibodies, anticardiolipin antibodies, and antibodies to extractable nuclear antigens. Of note, the patient was not receiving any anticoagulation. Blood cultures for mycobacteria and fungi, human immunodeficiency virus serology, and urinalysis and culture were negative. The patient subsequently developed an inferior wall myocardial infarction and was transferred to the coronary care unit. In line with the family's request, aggressive care was ceased and the patient expired. The patient's family refused an autopsy.

A 36-year-old woman without overt coronary risk factors was admitted to hospital with coma about 9 hours after mass self-injection of insulin (1,500 units). Laboratory investigation revealed severe hypoglycemia and hyperinsulinemia. During the treatment of her hypoglycemia, circulatory collapse occurred. The ECG, echocardiogram, and elevation in troponin T suggested a diagnosis of myocardial infarction. Although the patient became apallic and developed systemic spasticity due to hypoglycemic brain damage, her hemodynamics improved with supportive care alone. Coronary angiography and myocardial scintigraphy performed later demonstrated a broad area of myocardial damage despite intact coronary artery circulation. The authors hypothesize that temporary coronary arterial narrowing or coronary arterial vasospasm induced by severe hyperinsulinemia contributed to the pathogenesis of the myocardial infarction. The possibility of myocardial infarction should be considered in patients with acute insulin poisoning.

Complex regional pain syndrome (CRPS) types I and II are neuropathic pain disorders that develop as an exaggerated response to a traumatic lesion or nerve damage, that generally affects the extremities, or as the consequence of a distant process such as a stroke, spinal lesion or myocardial infarction. It rarely appears without an apparent cause. CRPS of upper limbs after stroke is frequently today called shoulder-hand syndrome (SHS). The onset and severity of SHS appears to be related with the aetiology of the stroke, the severity and recovery of motor deficit, spasticity and sensory disturbances. Another important aetiological factor is glenohumeral subluxation. The physiopathology of the disease is still not known. In CRPS, there is an exaggerated inflammatory response and some chemical mediators have been identified and are present in the inflammatory soup around the primary afferent fibres that, through different processes, can induce hyper-excitability of the afferent fibres (peripheral sensitization). It is hypothesized that a localized neurogenic inflammation is at the basis of oedema, vasodilation and hyperhidrosis that are present in the initial phases of CRPS. The repeated discharge of the C fibres causes an increased medullary excitability (central sensitization). Another important factor is the reorganisation of the central nervous system, and in particular this appears to affect the primary somatosensory cortex. The central role of the sympathetic nerve is presently in doubt. However, it is thought that a sub-group of CRPS patients exists in whom a predominant factor is the hyper-activity of the sympathetic nervous system, and that it responds positively to sympathetic block. Diagnosis is clinical and there are no specific tests, nor pathognomic symptoms to identify this disease with certainty. Diagnosis of CRPS after stroke appears more complex than in other pathological situations: the paretic upper arm frequently appears painful, oedematose, with altered heat and tactile sensations and slightly dystrophic skin within a non-use syndrome. Some investigations can aid differential diagnosis with other diseases. Treatment may be non-pharmacological, pharmacological, with psychotherapy, regional anaesthesia, neuromodulation and sympathectomy. In any case there is little evidence that supports the efficacy of the interventions normally used to treat or prevent CRPS-SHS. The key to effective treatment undoubtedly lies in a an expert multidisciplinary team that is co-ordinated and motivated and that treats the disorder with individualised therapy.

Severe spasticity is a frequent and disabling complication in patients presenting disorders of consciousness (DOC) that hinders their rehabilitative process, and is strongly correlated with pain reducing patients' quality of life. In these patients, abnormal postures may occur as an expression of severe brain damage. Here we present the case of a 52-year-old man in decorticate rigidity following a hypoxic-ischemic encephalopathy due to myocardial infarction who showed improvement of spasticity of upper limbs following intake of levetiracetam combined with the conventional neurorehabilitation program.
