Impact between the brain and the cristae of the base normally results as a consequence of inertia when an obstacle is hit, followed by contusion, or intra-, sub- or extradural haematoma. The skull itself may be briken (usually at the interpilasters or the weak points of the pilasters) or dented. Denting resulted in the depression of a circular fragments or fragments, with compression of the dura mater or brain; this, in turn, may be contused, lacerated or even crushed. Spinal crash fractures usually involve the lumbar region. Neck fractures are rare. The picture may be one of clinical silence (local pain) or marked neurological involvement. Damage to the cord is expressed in the form of shock, complete flaccid para- or tetraplegia, complete loss of sensation below the lesion, loss of deep and superficial reflexes, urinary retention and rectal incontinence. Treatment is rendered complicated by profuse scalp haemorrhages, respiratory insufficiency requiring orotracheal intubation and assisted respiration, convulsions, which should be handled with care, since ordinary anti-epilepsy products may mask the onset of hypertension and haematoma. Swelling should be reduced with cortisones. Diuretics may be too brusque and lead to intracerebral haematoma. In the case of spinal injuries, particular care should be excercised in shifting the patient and conveying him to hospital. Where high neck lesions are suspected, the possibility of damage to the originating segments of the phrenic nerve must be borne in mind.

Jurors on criminal trials carry a considerable burden of responsibility. They determine the defendant's fate. Additionally, during trials they can be exposed to stressful, frightening, and sordid aspects of life. The stressfulness varies depending upon the nature of the trial, its length, the nature of the testimony and evidence, the jurors' interpersonal relationships, the difficulty establishing guilt or innocence, the public's attitude, etc. These experiences can create psychological and/or physical discomfort that can be transient and mildly or moderately intense, or more serious and constitute illness. The authors have studied juries of four criminal trials--two murder cases, one child abuse case, and one obscenity case. Forty jurors were interviewed. Twenty-seven had one or more discomforting physical and/or physiological symptoms. These involved gastrointestinal distress (10 jurors); generalized nervousness (4 jurors); heart palpitation (6 jurors); headaches (4 jurors); sexual inhibitions (4 jurors); depression (4 jurors); anorexia (4 jurors); faintness (2 jurors); and numbness, lump in throat, chest pain, hives, and flu (1 juror each). Seven of the jurors became clearly ill. Illnesses included: peptic ulcer reactivation and hives, phobic reaction, anxiety state and increased alcohol use, hypertensive episode and visual scotomata, sexual inhibition, chills, fever, and depression, and post-traumatic stress disorder.

Somatic symptoms are one of the leading reasons for medical outpatient clinic visits, with the most common symptoms having a prevalence of 10% or more. However, the usual diagnostic workups are often unproductive, with less than 1 in 5 symptoms having an organic explanation after the initial physical examination and laboratory testing. Therapy appears more effective for some symptoms than for others. Of patients with unspecified pain or gastrointestinal complaints, greater than 70% state that some type of treatment has been helpful, whereas less than 50% of individuals with fatigue, dizziness, numbness, insomnia, sexual dysfunction, anxiety, or depression report any relief. Future educational efforts and research need to focus on that majority of symptoms that are either psychiatric or unexplained, in order to improve our current evaluation and management strategies.

The anatomy and physiology of the epidural space and the mechanism of action, sites of action, and pharmacokinetics of analgesics administered by continuous epidural infusion are reviewed, and the efficacy, adverse effects, and postoperative indications for use of analgesics administered by this route are discussed. Narcotics selectively block pain conduction by occupying specific opiate receptors in the spinal cord. Local anesthetics provide analgesia by axonal membrane blockade; they also can produce nonselective sympathetic and somatic (sensory and motor) blockade in addition to analgesia. A narcotic-local anesthetic mixture should provide an additive analgesic effect, without an increase in the incidence of adverse effects. Comparative efficacy studies have shown that continuous epidural infusions of narcotics, local anesthetics, and narcotic-local anesthetic combinations, when used appropriately, may produce better analgesia than conventional bolus methods of pain relief. Continuous epidural infusions also offer a safety advantage over intermittent epidural injections because peak and trough levels of the analgesic agent are avoided. Adverse effects of epidurally administered narcotics include respiratory depression, pruritus, urinary retention, nausea and vomiting, and sedation. Adverse effects of epidurally administered local anesthetics include urinary retention, hypotension, numbness, motor weakness, tachyphylaxis, and, rarely, systemic toxicity. The cost of epidurally administered drugs is substantially higher than that for i.m. or i.v. narcotic analgesia, but this cost may be offset by other benefits such as a shorter hospital stay. Current studies suggest superior analgesia for the majority of surgical procedures with continuous epidural analgesia infusions compared with more traditional methods of providing analgesia.

This study was undertaken to explore the motivations and problems shared by adult orthognathic surgical patients over the age of 25. Objective findings included demographic information and reasons for seeking surgery. The majority of 65 respondents cited functional problems as their primary reason for seeking treatment. Eighty-nine percent were pleased with esthetic changes, and 83% responded that the functional problem had been corrected. For most, the greatest discomfort related to the surgery was the postoperative intensive care unit. Two of the most common side effects of the surgery were the loss of sensation in the lips and chin area and a short period of depression. Women had depression more often than men but were more enthusiastic about the final results of the procedure. Two major areas of interest to surgeons emerged from the research. First, although women have functional problems, the majority seem to have a desire for cosmetic improvement. Having a functional problem seemed to provide the psychological permission necessary to spend the time and money for a cosmetic change. The second point focused on the need for good communication between surgeon and patient. The patients who were more positive toward the procedure and more satisfied with the results were those who were better informed and who thought they had a good system of communication with the orthodontist, surgeon, and their respective staffs.

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.

Bereavement is the reaction to the loss of a loved one by death and usually occurs in three stages: numbness, depression, and recovery. The length of time it takes for bereavement to resolve varies from person to person. During the depression stage, the bereaved person may experience all the symptoms of the typical depressed patient, with the exception of retardation. However, a depressed patient has more symptoms than a bereaved person and reports feeling changed, not his or her usual self, whereas the bereaved person expects to have such symptoms. The essence of the morbidity of bereavement is the increased use of alcohol, tranquilizers, hypnotics, cigarettes, and other substances during this stressful time. Increased mortality occurs in men aged 75 years or younger in the first year of bereavement, but mortality does not increase in women or parents during that first year. Pathologic grief, defined as a continued depressive symptom, occurs in about 15% of bereaved persons when they are initially widowed. Treatment for the bereaved person should be that which is given to any depressed patient.

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.

The acute central nervous and cardiovascular effects of the local anesthetics ropivacaine and bupivacaine were compared in 12 volunteers in a randomized double-blind manner with use of intravenous infusions at a rate of 10 mg/min up to a maximal dose of 150 mg. The volunteers were all healthy men. They were familiarized with the central nervous system (CNS) toxic effects of local anesthetics by receiving a preliminary intravenous injection of lidocaine. The infusions of ropivacaine and bupivacaine were given not less than 7 days apart. CNS toxicity was identified by the CNS symptoms and the volunteers were told to request that the infusion be stopped when they felt definite but not severe symptoms of toxicity such as numbness of the mouth, lightheadedness, and tinnitus. In the absence of definite symptoms, the infusion was stopped after 150 mg had been given. Cardiovascular system (CVS) changes in conductivity and myocardial contractility were monitored using an interpretive electrocardiograph (which measured PR interval, QRS duration, and QT interval corrected for heart rate) and echocardiography (which measured left ventricular dimensions from which stroke volume and ejection fraction were calculated). Ropivacaine caused less CNS symptoms and was at least 25% less toxic than bupivacaine in regard to the dose tolerated. Both drugs increased heart rate and arterial pressure. Stroke volume and ejection fraction were reduced. There was no change in cardiac output. Although both drugs caused evidence of depression of conductivity and contractility, these appeared at lower dosage and lower plasma concentrations with bupivacaine than with ropivacaine.(ABSTRACT TRUNCATED AT 250 WORDS)

Since its introduction to North America in 1942, the use of epidural catheter analgesia has increased dramatically. Improved equipment, methods and medications have broadened its application to include among others, surgical anesthesia, chronic pain relief and the management of postoperative pain. Numerous techniques for epidural puncture and insertion of the catheter have been described. Although complications have been associated with placement of an epidural catheter, these are rare when performed by an experienced anesthesiologist. Epidural analgesia was first accomplished by blockade with local anesthetics. Bupivacaine has been called the local anesthetic of choice for epidural infusion. Bolus administration of epidural local anesthetics gives effective analgesia; however, its use is limited by brief duration and occasionally severe hypotension. Epidural local anesthetics have been administered by continuous infusion in an attempt to minimize side effects. Nevertheless, hypotension, as well as motor block, numbness, nausea and urinary retention have occurred. Epidural analgesia with local anesthetics is effective in relieving postoperative pain, but its safety and feasibility have been questioned because of the frequent, potentially serious side effects. These problems led to trials of epidural narcotics for postoperative pain management. The exact site of action of epidural narcotic analgesics is debatable; however, the bulk of evidence supports a direct spinal action. Epidural narcotics appear to specifically inhibit nociceptive stimuli. The prolonged and profound analgesia that occurs with epidural narcotics relative to parenteral administration is due to a higher concentration of drug reaching the CSF through the epidural route. Since nervous transmission is not completely blocked this technique cannot provide anesthesia during operation. Morphine has been the most frequently used narcotic for epidural analgesia. Results of several recent, randomized double-blind studies have shown that epidural narcotics give adequate analgesia comparable with that observed with epidural bupivacaine. Epidural morphine provides a greater duration of analgesia and may cause fewer side effects. Improved analgesia has been reported when epidural narcotics are used in combination with local anesthetics. Continuous administration of low dosage epidural narcotics has been shown to have less frequent side effects than bolus administration. Nevertheless, pruritus, urinary retention, hypotension and severe respiratory depression have been reported with both methods.(ABSTRACT TRUNCATED AT 400 WORDS)
