Measurement of muscle reflex time in radicular disorders of the lumbosacral region]

The results of studies performed by the authors show that time measurements of proprioceptive muscular reflexes (triceps surae and tibialis posterior reflexes) may be considered a valuable addition to methods of topical diagnosis of radicular disturbances in the lumbosacral region. The reflexes were tested in twenty normal subjects. There were found an intraindividual constancy of the respective reflex time with a maximum deviation of 2 ms as well as a lateral variability up to 1.3 ms. Radicular compressions resulted in an increase in reflex time by 2 to 66 ms or failure of the reflex potential to be recorded. The pathological cases were compared with clinical and neurological studies, positive myelographies using radiopaque substances, and results of surgical operations. Compared with the results of surgical operations, changes in reflex time indicated damage to the reflex arc in ninety percent of the cases.     

Diagnosis and differential diagnosis of myasthenia gravis]

The author describes the possibilities of diagnosis and differential diagnosis of myasthenia gravis. The data is based on the literature and on case reports of personal observations of more than 270 patients with myasthenia. He inaugurates his own classification of myasthenia comprising of 8 types, among which there is one particular clinical type, described first by the author. The different problematic types of myasthenia are discussed together with the most important diagnostic tests and the principles of differential diagnosis. The clinical and pathological study is completed by illustrations.     

Personality diagnosis of school-age children]

This paper discusses some selected methodical and metric problems of psychological personality diagnosis in both childhood and the period of youth. In additon to discussing a number of important questions concerning psychometric methods, the author deals with problems associated with personality diagnosis, sociometric methods, and fictitious situational tests, analyzing them by reference to data reported in the literature.     

Incidence of infantile cerebral lesions in children with behavioral disorders]

The delimitation of behavioural disturbances predominantly due to organic brain lesions from those caused by reactions due to environmental factors has practical importance for drug therapy and pedagogic guidance. Figures on the incidence of infantile brain lesions among children with behavioural disorders range from between 20 to 90%. However, comparison of the results is difficult, because different authors followed different aspects for the evaluation of their material. The authors have collected data from 497 children from the 3 to 15 year-old age group who suffer from behavioural disturbances: history, neurological and psychological findings, electroencephalogram, native x-ray picture of the skull, pneumo-encephalogram and echoencephalogram were reviewed for signs and findings suggesting infantile brain damage. Certain signs of intantile brain lesion were found in 28.6% of the children. Among the apparative diagnostic procedures without impairment to the patients, the electroencephalogram proved particularly suited for the support of the diagnosis. The most accurate data on the localization and extent of the lesion are provided by the pneumo-encephalogram. However, its performance is not possible or justified in each child.     

Cerebrospinal fluid diagnosis of multiple sclerosis]

Starting from the knowledge accumulated with respect to the etiopathogenesis and the components of immunoreaction a minimal to maximal program by steps has been developed for the cerebrospinal fluid (CSF) in multiple sclerosis (MS). It is based on fundamental methods (I), special supplementary methods (II), and relatively specific immunological methods (III). For MS five possible conditions of the CSF could be determined from alterations of cells and variations in protein: a (1) typically complete and (2.) typically incomplete immunoreactive encephalomyelitic (encephalitic) syndrome, a (3.) nonspecific CSF-syndrome of low degree and less typical character (in the sense of an acute or subacute irritation syndrome) an (4.) atypical syndrome of a considerable degree, and a (5.) normal condition of the cerebrospinal fluid. The significance of immunoreactive cerebrospinal fluid syndromes to the diagnostic criteria of multiple sclerosis as well as further relatively disease-specific methods (such as the MEM test and MSF assay) of determining cellular immunity, are discussed.     

Incidence of anovulatory menstrual cycles among dysmenorrheic and non-non-dysmenorrheic [corrected] women: effects on symptomatology and mood

The incidence of spontaneous anovulatory (SA) menstrual cycles among dysmenorrheic and non-dysmenorrheic women and their effects on symptomatology and mood were examined in 52 university students distributed into two groups (18 dysmenorrheic women and 34 non-dysmenorrheic women) according to the presence or absence of symptoms of primary dysmenorrhea. Women were tested in menstrual, ovulatory and premenstrual phases. In order to estimate the proportion of ovulatory and SA cycles the basal body temperature (BBT) method was used. Results indicated that the percentage of SA cycles found in dysmenorrheic women does not confirm that primary dysmenorrhea only occurs in ovulatory cycles. In addition, the ovulatory cycles did not present greater symptomatology than the anovulatory cycles in self-rating of negative affect. In fact, menstrual symptomatology was not associated with ovulatory cycles. These data confirm that primary dysmenorrhea does not only depend on the endocrine factors which regulate the menstrual cycle but also on other factors such as social or psychological ones.     

Casuistic contribution to the differential diagnosis of the myoclonic syndrome]

Involuntary muscle twitches, which are accompanied by a more or less pronounced effect of motion and which may last for several hours, are a common guiding symptom of a number of neurological syndromes. This paper reports the case of a 24-year-old male who had been suffering since his sixth year from episodic muscular spasms accompanied by attacks of petit mal. These are regarded as representing a myoclonic-epileptic syndrome. In this connection, a distinction has to be made, by differential diagnosis, between the "true" myoclonic syndrome which is characterized by the absence of complications due to attacks of grand mal or petit mal, Kojewnikoff's epilepsy, and the myoclonic-epileptic dementia form of syndrome.     

The personality of the teacher as a patient type in psychological diagnosis]

The report concerns the questioning of 200 pedagogues using the questionnaire concerning introversion, neuroticism, rigidity and autonomic instability. All the patients are teachers and pupils in working relationships who were chosen from medical dispensary care with present symptoms of exhaustion and conflicting reactions, and who were transferred to psychological supervision. From the resulting data in the scales investigated, a configuration frequency analysis of the symptoms of introversion, neuroticism, rigidity and autonomic instability is given. Three oft-occurring typical configurations of scale can be found. From this a configuration type (with stikingly rigid behaviour and an otherwise unobtrusive scale constellation) can be interpreted as the "typical tacher" product of lengthy pedagogic activity.     

The Incidence of Workplace Bullying

This paper reports on a survey into workplace bullying carried out at Staffordshire University in 1994. The 1137 respondents were part time students at the University. Approximately half the sample reported they had been bullied during their working lives. Apart from the gender of the bully, there were no significant differences in the bullying experience between men and women in the parameters examined in this paper. Many people reported being bullied in groups, which is contrary to the current anecdotal evidence. Those who had not been bullied anticipated a more assertive reaction to the situation than those who had been bullied actually took. Data are presented and the findings are discussed, and future research potential identified. © 1997 John Wiley & Sons, Ltd.     

Incidence of having dreamed and conservative political attitudes

The association of political attitudes of conservatives and reports of their having had a dream was investigated. 48 female graduate students in counseling psychology were given the KJP Dream Inventory and the Kerlinger Social Attitude Scale II. Scores on conservative political attitudes were positively correlated with having had Dreams of Falling (.40), Dream Discontentedness (.31), Dreams of Being Chased (.40), and Dreams of Being Famous (.30). Negative correlations were observed between scores showing a conservative political tendency and scores on Openness (-.35), and Uninhibitedness (-.50), as well as incidence of Dreams of Sex (-.29). The character of conservative dreaming is discussed along with the study's relevance to past and subsequent issues in research.     

Changes of lumbosacral joint compression force profile when walking caused by backpack loads

Walking with backpack loads induces additional mechanical stress on the spine and has been identified as a risk factor of lower-back pain. This study evaluated the effects of walking with backpack loads on the lumbosacral joint compression force profile in both the magnitude and time domains. Ten male adults geared with anatomical markers and trunk surface electromyographic sensors walked along a walkway embedded with three force plates with no load and various backpack loads (5%, 10%, 15%, and 20% body weight). Lower-body movements, ground reaction forces, and trunk muscle activations were measured using a synchronized motion analysis, force plate, and surface electromyography system. The force profiles of identified gait cycles were predicted using an integrated inverse dynamic and electromyography-assisted optimization model and evaluated statistically. The results showed that as backpack load increased, the 10th, 50th, and 90th percentiles of force profiles escalated disproportionately. However, no significant changes were observed in the timing of the two peak force incidences. Such changes in the compression force might be an indication of the combined effects of the increase in both gravitational and mass moment of inertia of the system (body plus pack loads) when walking with a backpack. Pearson correlation coefficients of the force profiles between the five loading conditions were greater than 0.94. Strong associations between the force profiles at different backpack loads were confirmed.     

Changes in muscular activity and lumbosacral kinematics in response to handling objects of unknown mass magnitude

The aim of this study was to evaluate the main and interaction effects of mass knowledge and mass magnitude on trunk muscular activity and lumbosacral kinematics. Eighteen participants performed symmetric box lifts of three different mass magnitudes (1.1 kg, 5 kg, 15 kg) under known and unknown mass knowledge conditions. Outcome measures were normalized peak electromyography of four trunk muscles in addition to three dimensional lumbosacral angles and acceleration. The results indicated that three out of four muscles exhibited significantly greater activity when handling unknown masses (p < .05). Meanwhile, only sagittal angular acceleration was significantly higher when handling unknown masses (115.6 ± 42.7°/s²) compared to known masses (109.3 ± 31.5°/s²). Similarly, the mass magnitude and mass knowledge interaction significantly impacted the same muscles along with the sagittal lumbosacral angle and angular acceleration (p < .05) with the greatest difference between knowledge conditions being consistently occurring under the 1.1 kg mass magnitude condition. Thus, under these conditions, it was concluded that mass magnitude has more impact than mass knowledge. However, handling objects of unknown mass magnitude could be hazardous, particularly when lifting light masses, in that they can increase mechanical burden on the lumbosacral spine due to increased muscular exertion and acceleration.     

Incidence,Explanations, and Treatment of Partner Violence

Partner violence is a societal problem that cuts across all socioeconomic and racial/ethnic lines. Approximately 50% to 60% of couples presenting for counseling have reported at least 1 incident of violence in their relationship history. Many counselors are ill equipped to work with partner violence cases. This article provides an overview of partner violence research as it pertains to incidence, partner abuse typologies, etiology/explanation, and treatment. Developmental and integrated models for explaining and treating partner abuse are given particular consideration.     

Incidence of Savant Syndrome in Finland

The general incidence of Savant Syndrome was assessed in Finland. First, a survey was made of all 583 facilities which served people with mental retardation. Second, letters asking for information regarding people with Savant Syndrome were published in two key Finnish journals of the field. We received reports of 45 cases of Savant Syndrome. This makes an incidence rate of 1.4 per 1,000 people with mental retardation. The most common form of exceptional skills was calendar calculation, followed by feats of memory.     

社会经济地位对脑卒中发病率和死亡率的影响

社会经济地位是疾病与健康影响因素研究中的常用社会学指标,反映了社会成员社会地位的高低.众多研究显示,低收入、低职业等级均增加脑卒中发病和死亡的危险性;高社会剥夺亦增加脑卒中发病率.但这种影响存在年龄、性别和脑卒中亚型差异.在脑卒中预防与控制中,应关注低社会经济地位这一高危人群,并采取适当干预措施.
