Development of the quality of life in epilepsy inventory.

We developed an instrument to measure health-related quality of life (HRQOL) in epilepsy. A 99-item inventory was constructed from the RAND 36-Item Health Survey (generic core), with 9 additional generic items, 48 epilepsy-targeted items, and 6 other items concerning attitudes toward epilepsy and self-esteem. We administered the 99-item inventory to 304 adults with epilepsy at 25 epilepsy centers. Patients and patient-designated proxies completed the inventory and were retested 1-91 days later. A multitrait scaling analysis of these data led to retention of 86 items distributed in 17 multiitem scales (Cronbach's alpha ranged from 0.78 to 0.92). Factor analysis of the 17 multiitem scales yielded four underlying dimensions of health: an epilepsy-targeted dimension, a cognitive factor, mental health, and physical health. Construct validity was supported by significant patient-proxy correlations for all scales and correlations between neuropsychologic tests and self-reported emotional and cognitive function (all p values < 0.05). There were significant negative correlations between the four factor scores derived from the HRQOL scales and neurotoxicity, systemic toxicity, and health care utilization (except for the correlation between mental health factor and health care utilization; all p values < 0.05). Patients who were seizure-free in the preceding year reported better HRQOL for the overall score, three of the four factor scores, and 8 of the 17 scale scores than did patients with a high frequency of seizures. Relative validity analysis showed that the epilepsy-targeted factor and three of its four component scales were more sensitive to categorization of patients by severity of seizure frequency and type than scales tapping physical health, mental health, or cognitive function. These cross-sectional data support the reliability and validity of this measure of HRQOL in epilepsy. The addition of an epilepsy-targeted supplement to the generic core improved the sensitivity to severity of epilepsy. The 86 items included in the field testing were supplemented by three additional items to form the Quality of Life in Epilepsy (QOLIE-89) inventory.

Psychiatric morbidity in seizure patients on a neurodiagnostic monitoring unit.

This study aimed to clarify prevalence and type of psychiatric disorders among 97 consecutive patients with seizures who were admitted for neurodiagnostic monitoring. Of the 97 patients, 33 (34%) had an atypical mood disorder, 21 (22%) had pseudoseizures, and 9 (9%) had other psychiatric disorders, for a total of 63 (65%) in need of psychiatric treatment. Patients with the atypical mood disorder had predominantly depressive symptoms, which occurred intermittently, were associated with episodes of irritability, and alternated with briefer euphoric moods. Anxiety and phobic symptoms occurred less often. The existence of an epilepsy-specific mood disorder is suggested.

[Injuries in field hockey].

Frequency and mechanisms of injuries in field hockey are evaluated in a retrospective study of 322 players. Each athlete sustains 0.6 (female) respectively 1.0 (male) injuries per season on the average, mostly minor lesions. Severe injuries are mostly due to the playing surface; especially astroturf seems to be dangerous. The risk during match exceeds the risk during practice by a factor of 10.36% are typical field hockey injuries as they are caused by ball or stick. 62% of the lesions are related to the lower limb, 19% to the upper limb (mainly hand and fingers), and 19% to head and trunk. The data allow to draw conclusions concerning preventive measures.

Verbal recognition memory performance in unilateral temporal lobe epilepsy.

Recognition memory performance of 91 left and right unilateral temporal lobe epilepsy (TLE) patients was examined prior to and post anterior temporal lobectomy. The left TLE group showed more impaired response discrimination ability than the right TLE group; however, their false positive rate varied as a function of distractor type. Prior to temporal lobe resection, false positives were higher for semantically related distractors (novel or from an interference list) than for semantically unrelated items from an interference list, phonemic distractors, or unrelated errors. Following temporal lobe resection, only novel semantically related distractors in the left TLE group showed a significant increase in false positives, and they were also significantly higher than all other error types. The results of this study suggest that the left TLE patients have impaired individual item recollection in the context of intact information about basic semantic attributes.

Psychopathology in epilepsy. The role of psychology in altering paradigms of research, treatment, and prevention.

This article offers a brief review of the literature examining epilepsy and abnormal behavior. The generally accepted concept of epilepsy as a high psychiatric risk disorder is reexamined in light of research that has investigated the influence of selection bias. A conceptual model that organizes the known or postulated risk variables (neurological, psychosocial, and medication) is presented, with emphasis on psychology's potential contribution.

[Tarsal tunnel syndrome after fibular ligament repair. A rare complication of surgical therapy of chronic instability of the ankle joint ligament].

A case of tarsal tunnel syndrome following a reconstructive procedure with repair of chronic ankle instability using periosteal flap is reported. Two pathogenetic factors have to be discussed as possible causes for this complication. Dissection of the medial retinaculum was performed. With this procedure the patient is complaints could be removed.

[Significance of drug determination in pilocarpine sweat for detection of past drug abuse].

The presence of cocaine, morphine and methadone in sweat samples obtained after stimulation of the eccrine sweat glands, from drugs users after six drugs-free days, was investigated. The stimulation of the sweat elimination was proved using pilocarpine-iontophoresis every hour for 7 hours. The drugs concentrations were determined by radioimmunoassay. Consequently, the values measured represent the sum of the drug and its metabolites. Measurable levels of cocaine, morphine and methadone were obtained after the third stimulation of the glands.

[Development of loss-of-limb coverage in private accident insurance].

The oldest known private accident insurance is recorded in the maritime law of Wisby of 1541. Defoe is the first to propose a compensation scale for loss of limbs in the 17th century. It is taken over in a modified character by all insurance companies being founded in Europe and North America since 1850. The structure of the present insurance conditions originates in the conditions of 1920. Since then the loss of the right and left upper limb is rated equally. The compensation scale is changed again in 1961, the loss of extremities is valued higher and the loss of sense of smelling and tasting is considered.

[Chronic impingement syndrome of the shoulder].

The most common manifestation of periarthritis of the shoulder is the chronic impingement syndrome, which represents an "entrapment situation". When the arm is raised, the supraspinatus tendon that forms part of the rotator cuff, comes into contact with the coracoacromial arch. The complains can often be improved by conservative treatment. If, however, the problem persists--in about 10 to 20% of the cases--surgical decompression of the coracoacromial arch by resecting the coracoacromial ligament and the subacromial bursa is indicated. This limited intervention carries only a low risk and, as studies have shown, has such a high rate of success that, in the individual case, the indication for surgery can be established earlier than has so far been assumed.

[Topography of the upper biceps tendon segment].

26 shoulders are studied by polariscopic and histologic examination. It can be confirmed that the origin of the long biceps tendon is not only at the supraglenoid tubercle, but also y-shaped in the glenoid labrum. This finding can be explained by phylogenetic means. Further details are found during the course of the tendon through the bicipital groove. A mesotenonium is seen regularly. This is fixed either to the roof or the ground of the sulcus by a band of connective tissue. It is shown also, that the roof of the groove is not a ligament (ligamentum transversum humeri) but consists of collagen fibers continuing from the subscapularis and capsular attachment at the lesser tubercle.

Arterial supply of the human long biceps tendon.

The present study deals with the question whether an insufficient vascular supply of certain areas can be made responsible for ruptures in the biceps tendon. The macroscopic and microscopic examination shows that the blood supply of the tendon in the part most prone to ruptures, that is in the bicipital groove, is guaranteed even in older individuals. It is at least much better than in the intra-articular portion where ruptures are seldom observed. This means that mechanical components such as friction are dominant. The vascular factors seem to play a minor part.

[Shoulder and transducer position in sonographic soft tissue diagnosis. Anatomic principles].

The positions of the arm and of the transducer for the sonographic detection of soft tissue disorders of the shoulder have not yet been standardised. Anatomical studies were performed on 16 shoulders in different rotatory positions according to applied sonographic planes. 4 images in 3 different shoulder positions are necessary to evaluate the clinical important areas as completely as possible. With regard to the time and cost involved, this expenditure is acceptable in daily routine work.

Collagen fiber arrangement of the human shoulder joint capsule--an anatomical study.

The polariscopic examination of isolated shoulder joint capsules shows that the entire capsule does not have a homogeneous collagen structure. Most of the capsule is characterized by regular collagen fibers which cross at an obtuse angle in the area of the musculus supraspinatus and at an acute angle in the area of the m. infraspinatus. The density of the collagen network increases from the medial to the lateral part. Deviating from this basic pattern of the joint capsule, there is a different collagen texture in the area between the m. supraspinatus and the m. subscapularis. This texture has dissociated, rarefied and irregular collagen fibers. This means that the area--in comparison with the remainder of the capsule--is characterized not only by missing reinforcing ligaments but also by a deviating pattern of the collagen fibers. This different collagen structure is already existent in the fetus.

[Current and known aspects of the arterial supply of the rotator cuff].

The basic arterial supply of the shoulder is well known, some details for example the supply of the m. supraspinatus are not studied yet. Preparation of shoulder-specimens after injection of silicone-caoutchouc are done to examine the vascular system. The arterial supply of the shoulder is described as a system of four rings. The results are discussed in combination with the literature.
