We report a case of rubral infarct involving adjacent ipsilateral thalamic structures in a 54-year-old man with hypertension and coronary heart disease. Clinical picture at onset was suggestive of Weber's syndrome leading to a Claude's syndrome with vertical gaze palsy and sleep disturbances. Single photon emission computed tomography using Hm-PaO-Tc revealed a crossed cerebellar diaschisis. This is, to our knowledge, the first case of such crossed cerebellar diaschisis in a patient with rubral infarction.

Despite increased interest in dementia and the concomitant creation of dementia assessment centers, there has been a paucity of reports examining racial differences in the social and clinical presentation of dementia. Such information can enhance knowledge about dementia and assist in the planning of diagnostic centers located in areas with large minority populations. This study reviewed the charts of patients evaluated at a dementia assessment center in New York City. The sample comprised 102 white and 68 black patients. There were no racial differences in types of dementia nor reported length of illness. However, bivariate analysis revealed many significant differences between the groups in social, medical, and psychiatric variables. Most notably, a stepwise discriminant analysis identified seven variables--Medicaid recipient, gender, age, sleep disturbances, delusions of stealing, hypertension, and concentration--as correctly being able to classify 75% of cases. Racial differences in cognitive and behavioral symptoms may reflect the interaction of dementia with physical health, premorbid history, environment, or some basic difference in disease course.

Sleep apnoea (SA) ist a challenge to clinical research, since it occurs in up to 10% of the male professionally active population. It is indeed a challenge in respect of diagnosis, clinical aspects and therapy. SA is not only responsible for mental handicaps during daytime caused by disturbed sleep (increased tendency to doze or fall asleep, proneness to accidents), it will also enhance morbidity and mortality in aspect of cardiopulmonary and cardiovascular diseases (hypertension, cardiac insufficiency, disturbances of cardiac rhythm). All kinds of secondary and/or subsequent damage are reversible, provided diagnosis and rigidly introduced and maintained treatment have been performed well in time. SA can be diagnosed, treated and followed up by means of methods that can be flexibly employed outside the hospital, i.e. on an outpatient basis, such as questionnaires, MESAM IV, behavioural counselling, drug therapy). Within the framework of the current three-year project a stepwise concept was developed for diagnosis and treatment that also includes outpatient examination procedures. This system integrates anamnesis, outpatient monitoring, sleep laboratory, therapy and therapy control into a comprehensive feedback system of patient care. The following standardised procedural steps are included in the outpatient part of this system: baseline examination, treatment that can be performed on an outpatient basis, short-term, medium-term and long-term therapy follow-up. If these steps do not yield satisfactory results or if there is a high acute risk, the patient is subjected to in-patient treatment. At present, 683 first examinations and 420 follow-ups have been recorded.(ABSTRACT TRUNCATED AT 250 WORDS)

Two train conductors had chest tightness, painful breathing, muscle cramps, and nausea after fighting a fire in a battery box under a passenger coach. Shortly thereafter, they became anosmic and had excessive fatigue, persistent headaches, sleep disturbances, irritability, unstable moods, and hypertension. Urinary cadmium and nickel levels were elevated. Neurobehavioral testing showed, in comparison to referents, prolonged reaction times, abnormal balance, prolonged blink reflex latency, severely constricted visual fields, and decreased vibration sense. Test scores showed that immediate verbal and visual recall were normal but delayed recall was reduced. Scores on overlearned information were normal. Tests measuring dexterity, coordination, decision making, and peripheral sensation and discrimination revealed abnormalities. Repeat testing 6 and 12 months after exposure showed persistent abnormalities. Cadmium and vinyl chloride are the most plausible causes of the neurotoxicity, but fumes from the fire may have contained other neurotoxic chemicals.

Our purpose in conducting this descriptive study was to assess the health-related concerns and experiences of a sample of employed perimenopausal women in Alexandria, Egypt. In addition, we explored their help-seeking behavior and their perception of symptoms. We interviewed two hundred working women ages 40-60 years, 42% of whom were nurses, using a semistructured interview form as well as Koos's list of symptoms. The commonly mentioned concerns, in order of frequency, were chronic headaches, chronic fatigue, transportation and phone communication problems, financial problems, job dissatisfaction, backaches, hypertension, kidney disease and gall bladder disease, gastritis/indigestion, menstrual disturbances, arthritis, AIDS, and hepatitis B. With respect to the problems experienced by the women in the past 6 months, there was a high self-reported prevalence of headaches, fatigue, transportation and communication problems, backaches, job dissatisfaction, dissatisfaction with health insurance, financial problems, menstrual disturbances, gastritis/indigestion, gall bladder disease, anxiety, disturbed sleep, and hypertension. Women attempted to manage their problems mainly by taking over-the-counter drugs and self-prescribing (75.5%), doing nothing or using traditional remedies (56.5%), and going to a doctor or health insurance office (40%). Symptoms perceived by the majority of the women as not needing medical attention included loss of appetite, persistent backache, bleeding gums, chronic fatigue, persistent headaches, and loss of weight. The influence of education and occupation on women's perceptions and practices is discussed.

Application and feasibility of automated ambulatory blood pressure measurement (ABPM) in the elderly are comparable to younger age groups. Major side-effects are sleep disturbances and pain during cuff-inflation. The main indications for ABPM are diagnosis and control of treatment in hypertensive patients. Further indications are the diagnosis of syncope or hypotensive disorders and the diagnostic work-up of symptoms like vertigo, dizziness and dyspnea. In hypertensives, ABPM can easily assess the "white coat" effect and cases of "white coat" hypertension (prevalence in the elderly 15-25%). The prognostic implications of "white coat" hypertensions remain to be determined. Recording of the total 24-h blood pressure profile with analysis of circadian blood pressure changes, the day-night difference and the early morning surge raises the possibility to assess age-specific patterns. The drop in blood pressure at night (during sleep) is usually decreased and less frequently observed in elderly hypertensives. Possible explanations include decreased daytime activity, an altered sleep pattern in the elderly and secondary forms of hypertension. So-called "non-dippers", with no adequate drop in night-time blood pressure, show a significant increase in cardiovascular complications. Control of treatment via ABPM can assess non-responders and cases of overtreatment, and permits a fairly objective analysis of side-effects. Episodes of transient myocardial ischemia and possible trigger mechanisms can be assessed by simultaneous application of ABPM and Holter monitoring. The insufficient control of hypertension in the majority of elderly patients and the current lower target blood pressures in the elderly call for new methods to improve the level and quality of antihypertensive treatment. Although ABPM provides a closer correlation to target organ damage than measurement of office (casual) blood pressure, and ABPM frequently improves or at least facilitates the care of elderly hypertensive patients, it remains to be determined whether ABPM can finally improve the long-term outcome of these patients.

Nocturnal hypertension is of diagnostic interest and has important prognostic and therapeutic implications. Nighttime blood pressure can easily be measured using ambulatory blood pressure monitoring (ABPM). However, during nocturnal ambulatory blood pressure measurement pump noise, tactile stimuli and pressure produced by cuff inflation may alter the quality of sleep and subsequently influence the physiological fall of night time blood pressure. Eight studies were performed to determine whether non-invasive automated blood pressure monitoring during day and/or night provokes alert reaction, arousal, sleep disturbances and changes in blood pressure and/or heart rate. From these studies it can be concluded: 1) Nighttime blood pressure can be evaluated properly using ABPM. 2) Nocturnal blood pressure is not overestimated by ABPM. 3) ABPM does not induce an alarm reaction and a blood pressure rise when monitored with a silently operating recorder. 4) Sleep is often disturbed by blood pressure measurement without provoking a blood pressure increase. 5) In older patients blood pressure measurement and age-related alterations in sleep quality may influence each other. A patient's protocol has to be carried out and sleep quality should be recorded to provide a proper interpretation of nocturnal blood pressure behavior. ABPM is an important and valuable method to record nocturnal blood pressure for diagnostic and therapeutic purposes.

The objectives of this study were to describe the prevalence of snoring, observed apneas, and daytime sleepiness in older men and women, and to describe the relationships of these sleep disturbances to health status and cardiovascular diseases (CVD). A cross-sectional design was employed to study sleep problems, CVD, general health, psychosocial factors, and medication use. The subjects were participants in the Cardiovascular Health Study, which included 5,201 adults, aged 65 and older, who were recruited from a random sample of Medicare enrollees in four U.S. communities. Study measures employed were sleep questions, echocardiography, carotid ultrasound, resting electrocardiogram, cognitive function, cardiopulmonary symptoms and diseases, depression, independent activities of daily living (IADLs), and benzodiazepine use. Thirty-three percent of the men and 19% of the women reported loud snoring, which was less frequent in those over age 75. Snoring was positively associated with younger age, marital status, and alcohol use in men, and obesity, diabetes, and arthritis in women. Snoring was not associated, however, with cardiovascular risk factors or clinical CVD in men or women. Observed apneas were reported much less frequently (13% of men and 4% women) than snoring, and they were associated with alcohol use, chronic bronchitis, and marital status in men. Observed apneas were associated with depression and diabetes in women. In both men and women, daytime sleepiness was associated with poor health, advanced age, and IADL limitations. The conclusions of the study were that loud snoring, observed apneas, and daytime sleepiness are not associated cross-sectionally with hypertension or prevalent CVD in elderly persons.

In this study fibromyalgia sufferers were randomly administered a combination of monoamine-oxidase inhibitors (MAOIs)-A/B with 5-HTP, 5-HTP alone, MAOIs-A/B alone, or the tricyclic drug amitriptyline in order to compare the efficacy of these treatments. The benefits on the painful syndrome were assessed by using Visual Analogic Scale score rating from 0 to 4. The combination of MAOIs with 5-HTP significantly improved fibromyalgia syndrome as determined by Visual Analogic Scale whereas the other treatments yielded poorer benefits. No subject withdrew from the trial due to adverse effects, even if some sleep disturbances and mild stomach-ache were reported. The tolerability of the association MAOIs/5-HTP was good, although a transient cheese effect occurred in one of the patients treated with MAOIs as well as in a patient treated with the association MAOIs and 5-HTP. No one of these two cases was due to pharmacological dietetic mistake of the patient. In both the cases the transient hypertension was associated to very dramatic emotional events. The benefits obtained by using the combination of MAOIs with 5-HTP can be explained with a treatment-induced enhancement of aminergic and serotonergic transmission. The recently shown high prevalence of migraine in the population of fibromyalgia sufferers, suggests a common ground shared by fibromyalgia and migraine. Migraine has been demonstrated to be characterized by a defect in the serotonergic and adrenergic systems. A parallel dramatic failure of serotonergic systems and a defect of adrenergic transmission have been evidenced to affect fibromyalgia sufferers too. Enhancing serotonergic analgesia while increasing adrenergically mediated analgesia seems to be an important tool in fibromyalgia. Treatment consisting with the association MAOIs/5-HTP is aimed at enhancing serotonergic/adrenergic transmission by inducing an up-regulation of serotonergic/adrenergic receptors and a simultaneous increase of serotonin levels in the central nervous system.

The number of patients treated with interferon (IFN) has increased markedly in Japan since 1992, when the Health and Welfare Ministry approved the use of IFN for treating chronic active hepatitis C. It is important to identify and treat depression, which is one of the psychiatric complications of IFN therapy and often leads to discontinuation of the therapy, in patients with chronic hepatitis C. In this study we prospectively investigated the incidence of depression during IFN therapy in patients with chronic active hepatitis C. The psychiatric status of 85 patients (53 men, 32 women; mean age 49.1 years) with chronic active hepatitis C who began receiving IFN at Showa University Hospital was assessed before and 2, 4, 12 and 24 weeks after the start of IFN therapy, using the major depressive episode diagnostic criteria listed in the DSM-III-R and the Hamilton Depression Scale HDS). All of the patients provided informed consent prior to participation in this study. IFN therapy was discontinued in 5 cases (5.9%) because of physical side effects and in 4 cases (4.7%) because of depression. Two, 11, 14, 25 and 16 patients were diagnosed as having major depressive episodes before and 2, 4, 12 and 24 weeks after the start of IFN therapy, respectively. The number of patients who were asymptomatic before the start of IFN therapy but were diagnosed as having a major depressive episode at least once during IFN therapy was 31 (31/83 = 37.3%). The mean HDS scores at 2, 4, 12 and 24 weeks (5.4, 6.0, 8.8 and 6.6) were significantly higher than that before the start of IFN therapy (3.0). The patients whose first diagnosed major depressive episodes occurred more than 4 weeks after the start of IFN therapy tended to be more severely depressed than those in whom it occurred less than 4 weeks after the start of IFN therapy. Compared to the 47 patients who completed 24 weeks of IFN therapy without experiencing depression, the 31 patients who were diagnosed as experiencing major depressive episodes during IFN therapy had significantly higher neuroticism scores determined using the Eysenck Personality Questionnaire, showed a more severely depressed mood and experienced more severe sleep disturbances before the start of IFN therapy. The latter group of patients also tended to have comorbid chronic physical disorders such as hypertension or diabetes mellitus and the histories of mental disorders before the IFN therapy; however these differences were not statistically significant. There were no differences between the two groups in patient age or sex, the severity of hepatitis before the IFN therapy, the type of IFN used in the therapy or the efficacy of IFN in the treatment of the hepatitis C. Our results indicate that the decision as to whether to treat chronic active hepatitis C with IFN should be made carefully and that early intervention and careful monitoring of depression are required during IFN therapy in the treatment of chronic active hepatitis C.
