A 68-year-old man was admitted to our hospital because of numbness in the hands and feet, and unsteady gait in August, 1986. On neurological examination, deep tendon reflexes were absent in all limbs without pathological reflexes. Superficial and deep sensory disturbances of a glove and stocking type up to the level of the elbow and the knee were observed. Pseudoathetosis was noted in the hands. His gait was ataxic and Romberg sign was positive. Muscle strength was slightly decreased. Sural nerve biopsy showed severe loss of large myelinated fibers. Laboratory studies for malignancy showed lung cancer (Squamous cell carcinoma). Left pneumonectomy was performed in November, 1986, but he died in March, 1987. At autopsy, neither metastasis nor direct infiltration of malignant cells in the central and peripheral nervous systems were present macroscopically and histopathologically. Degeneration of the dorsal root ganglion and the posterior columns of the spinal cord were remarkable. Since 1955, only 9 cases of subacute sensory neuropathy had been reported in Japan. We analysed 10 Japanese cases (including our case) to clarify the clinicopathological features of subacute sensory neuropathy. Clinically, ataxic gait, paresthesia, deep sensory disturbance, and depression of deep tendon reflexes were present in the majority of the cases. Neuropathologically, neuronal cell loss and degeneration of the dorsal root ganglion, posterior roots and posterior columns of the spinal cord were universal findings.

The effects of conditioning stimulation of a mixed nerve in the leg, the common peroneal nerve (CPN), on the ipsilateral soleus H-reflex were compared with the effects of stimulating its cutaneous branch, the superficial peroneal nerve (SPN), in two groups of subjects--normals and patients with spinal spasticity subsequent to a clinically complete transection of the spinal cord. Condition-test delays of 20 msec to 2 sec, measured from the end of the 20 msec train (3 pulses at 100 Hz), were investigated. In normal subjects, CPN stimulation at 1.4 X MT profoundly depressed the soleus H-reflex. There was an initial depression (peak 40-90 msec) followed by a slow recovery which was incomplete at condition-test delays of 2 sec. One-half of the subjects showed a late facilitation, or disinhibition, peaking at 170-190 msec. The inhibitory effects were attributed to activation of low threshold, groups I and II, muscle afferents because stimulation of the SPN, at 1.5 X threshold for a compound action potential recorded from the CPN, had only facilitatory effects on the soleus H-reflex. Facilitation occurred at condition-test delays of 30-190 msec. The cutaneous stimulation was presumed to activate the largest, A beta, cutaneous afferents as it elicited a weak paraesthesia on the dorsum of the foot. The results suggested that cutaneous afferents may have contributed to the late facilitation seen with CPN conditioning stimulation. In spinal cord-lesioned subjects, CPN stimulation depressed the soleus H-reflex but the decrease was less and the recovery was faster and more complete than in normals. The magnitude of the initial depression at 20-100 msec varied with the severity of the spasticity, subjects with mild spasticity showing less of a depression. Weak cutaneous conditioning stimulation either had no effect or produced a slight depression of the soleus H-reflex, providing clear evidence that transmission in the pathways mediating the facilitatory effects of cutaneous afferents onto extensor motoneuronal pools is depressed in spinal spasticity. This may shift the balance of activity toward the flexor motoneurones, thus favouring the development of, for example, flexor spasms and flexor hypertonia. Since inhibitory effects from cutaneous stimulation are associated with activation of higher threshold afferents in normal man, the present results may reflect a decrease in the threshold for flexor withdrawal reflexes commonly associated with spasticity of spinal origin.

Electrocardiographic (ECG) monitoring was performed on 291 donors during apheresis. Twenty-one donors (7.2%) had clinical symptoms such as discomfort, nausea, chill, numbness, and paresthesia, and 13 of this group exhibited ECG abnormalities, such as tachycardia, bradycardia, and other abnormal wave patterns. The donors with tachycardia and slight bradycardia had no symptoms. Ten donors had moderate to severe bradycardia with pulse rates less than 50 beats per minute; four of them had severe bradycardia (less than 45 beats per minute), and three of the four exhibited severe hypotension, vomiting, fainting, or convulsion. Other abnormal ECG changes, such as supraventricular and ventricular premature contractions, right bundle branch block, ST segment elevation or ST segment depression, and tall, flattened, or inverted T waves were observed in 29 donors (10%). These changes were not associated with symptoms. Only three of these donors complained of discomfort or chest heaviness. The abnormal waves appeared more often in granulocytapheresis donors than in plateletapheresis donors.

Experience at University Hospitals of Cleveland with 71 cases of Gardner and Diamond's syndrome of autoerythrocyte sensitization is reviewed. Gardner and Diamond attributed the pathogenesis of the inflammatory bruises typical of this syndrome to sensitization to the stroma of the patients' own erythrocytes, as demonstrated by reproduction of the lesion on intracutaneous injection of erythrocytic stroma. Nearly all the cases my colleagues and I have seen were in adult women, in whom the onset of inflammatory bruising could often be precisely dated, frequently some weeks after an injury or surgical procedure or, more often, severe emotional stress. Bouts of bruising were often preceded by sensations localized to the affected site. Cutaneous responses to the injection of erythrocytes were erratic. The patients described a wide range of both hemorrhagic and nonhemorrhagic complaints, including, among others, severe headaches, paresthesias, repeated syncope, diplopia (sometimes monocular), and "nervousness." Psychiatric studies indicated that patients had overt depression, sexual problems, feelings of hostility, and obsessive-compulsive behavior. The patients had traits that can be described as typical of a hysterical character disorder. Therapy of autoerythrocyte sensitization--that is, psychogenic purpura--has been difficult; in younger individuals, psychiatric therapy has appeared to be beneficial.

In 984 patients with generalized anxiety disorder who received buspirone in double-blind studies, the incidence of drowsiness (9 percent) did not differ significantly from that (10 percent) reported in 334 patients who received placebo. A probability value of p less than or equal to 0.10 was the criterion for significance. The incidence of drowsiness in buspirone-treated patients was significantly less than that in each of the groups receiving diazepam (32 percent), clorazepate (26 percent), lorazepam (58 percent), or alprazolam (43 percent). The side effects that did occur significantly more frequently in the buspirone group than in the placebo group were dizziness (9 percent versus 2 percent), headache (7 percent versus 2 percent), nervousness (4 percent versus 1 percent), light-headedness (4 percent versus less than 1 percent), diarrhea (3 percent versus less than 1 percent), paresthesia (2 percent versus less than 1 percent), excitation (2 percent versus less than 1 percent), and sweating/clamminess (1 percent versus 0 percent). The severities of these effects were predominantly rated as only mild or moderate. Fatigue occurred less frequently in buspirone-treated patients than in those receiving any of the benzodiazepines, and weakness occurred more frequently in diazepam-treated patients. Depression occurred less frequently in buspirone-treated patients than in those receiving clorazepate, diazepam, or lorazepam. Impotence occurred only in clorazepate- and lorazepam-treated patients. Decreased libido occurred more frequently in diazepam-treated patients, whereas increased libido was more frequent in clorazepate-treated patients. Nausea was reported more frequently in buspirone-treated patients than in those receiving clorazepate, diazepam, or alprazolam; diarrhea occurred more frequently in the buspirone group than in the diazepam group. The mean daily doses of the various treatments were buspirone, 20 mg; diazepam, 20 mg; clorazepate, 24 mg; lorazepam, 3 mg; and alprazolam, 1.5 mg. In an open-field study in West Germany involving 5,414 patients, gastrointestinal-related complaints were the most frequently reported side effects.

Seventy-four patients with chest pain and no prior history of organic heart disease were interviewed with a structured psychiatric interview immediately after coronary arteriography. The majority of patients with both negative and positive coronary angiographies had undergone previous exercise tolerance tests, but the patients with angiographic coronary artery disease were significantly more likely to have had positive results on a treadmill test. Patients with chest pain and negative coronary arteriograms were significantly younger; more likely to be female; more apt to have a higher number of autonomic symptoms (tachycardia, dyspnea, dizziness, and paresthesias) associated with chest pain, and more likely to describe atypical chest pain. Patients with chest pain and normal coronary arteriographic results also had significantly higher psychologic scores on indices of anxiety and depression and were significantly more likely to meet criteria of the Diagnostic and Statistical Manual of Mental Disorders, third edition, for panic disorder (43 percent versus 6.5 percent), major depression (36 percent versus 4 percent), and two or more phobias (36 percent versus 15 percent) than were patients with chest pain and a coronary arteriography study demonstrating coronary artery stenosis.

The case is described of a 43 year old woman with spasmophilic syndrome. For 12 years she had suffered from fainting fits, marked morning asthenia, anxiety, depression, widespread arthromyalgia, blood pressure fluctuations, precordial pains, paresthesia and painful nocturnal cramp. This clinical picture appeared in a subject with a double left kidney and stones in the supernumerary ureter, enlargement of the pancreatic head and tail revealed by a CAT scan and an earlier cholecystectomy. Given the multiplicity of symptoms diagnosis was necessarily by a process of elimination. The data providing grounds for optimism were a positive Chvostek's sign, stable calcium phosphorus profiles, a reduction in ionised calcium and favourable eletromyographic readings.

This clinical note describes an unusual phenomenon of referred sensation reported in a sample of 98 chronic pain patients during electrical stimulation. Thirty-nine percent reported a variety of sensations referred to different parts of the body. Of these, 74% reported the sensations referred to the painful region. Among the sensations were paresthesias, pain, temperature changes, and pressure or constriction. The patients who had referred sensations had lower ratings of depression and had undergone more surgical operations than those who did not report referred sensations. Three case reports of patients with phantom limb pain are presented to illustrate the vividness with which these sensations are experienced. These data suggest that deafferentation due to disease, injury or other lesions of the CNS lead to a hypersensitivity and an increased likelihood of referred pain of long duration.

Previous research by the authors has pointed to depressive reactions among orthognathic surgery patients during the fixation-removal stage and up to 9 months later. However, less is known about emotional shifts among persons who choose to undergo conventional orthodontic treatment after considering surgical orthodontics. In the current study, a standard measure of mood states was applied to 90 surgical patients and 66 who had considered surgery but decided against it. Of these, 33 were undergoing orthodontic treatment and 33 were having no treatment. The mood scale and measures of personality were first applied before surgery and then during orthodontic treatment, just after surgery, at fixation removal, and 6 months after surgery. Nonsurgical respondents completed questionnaires at the same time as their matched surgical respondents. Scores on tension and fatigue increased significantly among surgical patients from before surgery to immediately after surgery and dropped to presurgical levels when fixation was removed. Anger-hostility increased at fixation removal but declined within 5 months. Postsurgical discomfort, pain, and paresthesia, and interpersonal and oral function problems were correlated with postsurgery emotional state. On the later questionnaires, which corresponded to the later periods of orthodontic treatment, patients who had opted for conventional orthodontic treatment reported that they experienced greater depression, anger, and tension. These patients may be particularly vulnerable to emotional problems because their orthodontic treatment may be more complex and of longer duration than that of the typical orthodontic patient. These results point to the importance of continued psychological support for both orthodontic and surgical patients throughout their course of treatment.

This study evaluated 1 year the efficacy of therapy with nicardipine in patients with chronic stable angina pectoris. Twenty-five male patients were entered. After a placebo run-in phase, the patients received nicardipine 30 mg, nicardipine 40 mg, and placebo, three times daily given in random, double-blind manner for 8 weeks. A double-blind, cross-over study comparing nicardipine with placebo was then undertaken. After 5 months of open treatment with nicardipine 90 or 120 mg day-1, patients received either placebo or nicardipine for 3 weeks, each followed by the alternative treatment for an additional 3 weeks and further open-label treatment with nicardipine for another 3-5 months. There were no significant changes in the PR, QRS or QT intervals, or in the QRS pattern during the short-term and long-term studies. There were no significant differences in mean heart rate after nicardipine compared with baseline. During treatment with nicardipine 120 mg day-1, patients reported significantly fewer anginal attacks compared with placebo, and nitroglycerin consumption also decreased. Nicardipine increased treadmill time, time to onset of angina, and time to one mm ST segment depression. These effects were maintained after 6 months of continued nicardipine therapy. Adverse effects were minor and well tolerated and included headache, dizziness, gastrointestinal upset, flushing paraesthesia and pedal oedema. Abrupt withdrawal of nicardipine at the end of the study resulted in a rapid return of the original symptoms but without further deterioration from the baseline measurements. Nicardipine was effective in the treatment of stable effort angina pectoris; this benefit was maintained for the entire year of treatment.
