Non-convulsive status epilepticus with marked neuropsychiatric manifestations and MRI changes after treatment of hypercalcaemia

We describe a 77-year-old woman who developed a confusional state, cognitive impairment, behavioural abnormalities and dysphasia after treatment of hypercalcaemia. Repeated EEG recording revealed rhythmic sharp-wave activity over the right parietal-occipital lobe. Magnetic resonance imaging (MRI) showed marked hyperintense signal changes bilaterally. The diagnosis of a non-convulsive status epilepticus (NCSE) was made. With antiepileptic treatment the patient improved and MRI as well as EEG changes were almost all reversible. NCSE is an important differential diagnosis of patients with neuropsychiatric symptoms and can develop after rapid lowering of serum calcium levels in hypercalcaemia.

Hypertension as a risk factor for cardiovascular morbidity and mortality in an elderly German population; the prospective STEPHY II study. Starnberg Study on Epidemiology of Parkinsonism and Hypertension in the Elderly

AIM

To prospectively study the relationship between blood pressure levels and subsequent cardiovascular morbidity and mortality in a population aged 65 years and older.

METHODS

Participants of the 1992 baseline survey of the population-based Starnberg Study on Epidemiology of Parkinsonism and Hypertension in the Elderly (STEPHY, 394 men and 588 women above age 65) were followed up for 3 years. Total mortality was assessed by official death data. Cardiovascular morbidity, that is, the occurrence of non-fatal events (new cases of acute myocardial infarction, angina pectoris, stroke, and heart failure) could be assessed in 681 of the 863 survivors by a second interview and analysis of general practitioners' records. The mortality and morbidity risks were compared for hypertensives (baseline blood pressure > or = 160/95 mmHg or antihypertensive treatment) and non-hypertensives.

RESULTS

During follow-up a total of 55 men and 64 women died resulting in a 2.7-year cumulative mortality in this population of 12%. Mortality was higher in men (14%) than in women (11%). Hypertensives had no increased risk of death compared to non-hypertensives (adjusted relative risk (RR)=0. 92; 95% CI: 0.48-1.76 for men and RR=1.36; 95% CI 0.67-2.78 for women). This was confirmed in age-stratified analyses. However, among survivors hypertension was associated with a significantly higher occurrence of non-fatal cardiovascular events. After controlling for potentially confounding baseline conditions, the relative risk for any event (RR=1.44; 95% CI: 1.04-2.0) and, in particular, of acute myocardial infarction (RR=5.5; 95% CI: 1.6-18. 7) was raised among hypertensives. Higher rates for angina pectoris (RR=1.4; 95% CI: 0.9-2.4) and heart failure (RR 1.7; 95% CI: 0.9-2. 9) were of borderline significance. Positive risk associations were confined to the age group 65 to 75 years and not detected at higher ages.

CONCLUSION

This study demonstrates for a Central European population older than 65 years the impact of hypertension as a risk factor for cardiovascular and cerebrovascular morbidity. To address the issue that risk of death showed no significant relationship to blood pressure, a longer follow-up period might be necessary.

[Myocardial involvement in carrier states for Duchenne muscular dystrophy. A rare cause of supraventricular arrhythmia]

HISTORY AND CLINICAL FINDINGS

Two women, both aged 54 years, were admitted because of supraventricular arrhythmias of recent onset. Patient 2 was also in heart failure. Male family members of both patients were known to have Duchenne's muscular dystrophy, of which one had died.

INVESTIGATIONS

The electrocardiogram of patient 1 demonstrated atrial fibrillation. Patient 2 had a raised serum creatine kinase concentration and increased pulmonary marking in the chest radiogram. Patient 1 had normal findings on left heart catheterization, but immunohistochemical analysis of a myocardial biopsy revealed dystrophin mosaic with 20% dystrophin-negative fibres. Patient 2 had a reduced ejection fraction and 80% dystrophin-negative fibres.

DIAGNOSIS, TREATMENT AND COURSE

Myocardial involvement in the carrier state for Duchenne's muscular dystrophy having been demonstrated in both women, patient 1 received antihypertensive treatment while patient 2, who was in cardiac failure, was given diuretics, ACE-inhibitor and beta-receptor blockers.

CONCLUSION

Cardiomyopathy in carriers of Duchenne's muscular dystrophy is a rare cause of supraventricular arrhythmias. The cause can be confirmed by immunochemical analysis of an endomyocardial biopsy.

[Diagnostic error of thrombosis of the inferior vena cava with contrast-CT in tricuspid valve insufficiency]

Sonographic evidence of a cystic adrenal tumour was found in a 73-year-old female patient with a 6-month history of chest pain and dyspnoea. A computed tomogram of the abdomen revealed, in addition to the 5-cm lesion, a contrast medium-free area in the vena cava inferior, leading to an initial diagnosis of recurrent pulmonary emboli due to a thrombosis of the vena cava inferior. Further diagnostic procedures excluded emboli and indicated a dilating cardiomyopathy with mitral and tricuspid regurgitation. The contrast medium-free area in the vena cava inferior was caused by the influx and regurgitation of contrast medium-free blood from the renal and hepatic veins in addition to blood from the right atrium due to the tricuspid valve regurgitation. A thrombosis was excluded by means of a color-duplex investigation. The patient declined any further diagnostic procedures concerning the lesion.

Felodipine or hydrochlorothiazide/triamterene for treatment of hypertension in the elderly: effects on blood pressure, hypertensive heart disease, metabolic and hormonal parameters

The aim of the study was to compare the antihypertensive efficacy of either felodipine or the diuretic combination hydrochlorothiazide/triamterene in a group (n = 65) of elderly (> or = 70 years) hypertensives (office blood pressure > or = 160/95 mmHg) with special regard to ambulatory blood pressure monitoring, hypertensive heart disease and metabolic parameters. This was a randomized, double-blind study with a treatment period of 6 months. Reduction of office and 24-hr ambulatory blood pressure was comparable with both treatment regimens; after 6 months. 18 of 29 patients in the felodipine group (62%) and 20 of 27 patients in the diuretic group (74%; p = 0.4) were controlled. While episodes of ischemic type ST-segment depression were significantly reduced in the felodipine group (from 49 to 9 episodes), there was no significant change in the diuretic group (from 24 to 21 episodes). Both regimens decreased left ventricular wall thickness, but the decline in left ventricular muscle mass index was significant only for felodipine. Felodipine did not induce any change in metabolic or hormonal parameters; the diuretic combination significantly increased serum creatinine, uric acid, plasma renin activity, and plasma prorenin. Thus, the antihypertensive efficacy of felodipine and the diuretic combination was comparable in elderly hypertensives; only felodipine, however, improved parameters of hypertensive heart disease and showed a neutral metabolic and hormonal profile.

[Gastrointestinal amyloidosis in IgG-chi-light chain plasmacytoma. Diagnostic problems despite advanced changes]

A 50-year-old man with an IgG-chi light chain multiple myeloma stage IIIA, developed--in a phase of low disease activity, after 18 months of an uncomplicated course--marked malabsorption syndrome with 20 kg weight loss, diarrhoea and meteorism. Although the H2-breath test indicated intestinal bacterial colonisation, neither antibacterial treatment with trimethoprim/sulphamethoxazole and metronidazole nor prokinetic treatment with cisapride (30 mg daily) and erythromycin (1 g twice daily) improved the symptoms. Suspected amyloidosis was not demonstrable at first, despite repeated step biopsies of stomach, duodenum and rectum. Amyloidosis of the entire gastrointestinal tract was proven only by repeated biopsies deep into the submucosa. Despite treatment of the underlying disease with melphalan and prednisone (Alexanian's scheme) the amyloidosis advanced further to involve liver, spleen, lung, kidneys and heart. The patient died, 2 years after diagnosis of the multiple myeloma, from recurrent pulmonary emboli due to atrial fibrillation.

Antihypertensive treatment with felodipine but not with a diuretic reduces episodes of myocardial ischaemia in elderly patients with hypertension

Episodes of transient myocardial ischaemia can frequently be observed in hypertensive patients. To assess the effects of antihypertensive treatment with the calcium antagonist felodipine or the diuretic combination hydrochlorothiazidel triamterene on episodes of ischaemic-type ST-segment depression (ST-D), simultaneous ambulatory electrocardiographic and blood pressure (BP) monitoring was performed in 42 elderly hypertensives without manifest coronary artery disease. All patients (mean age 79 +/- 6 years, office BP > or = 160/95 mmHg) were evaluated off any antihypertensive or anti-ischaemic therapy and after 3 months treatment with either felodipine or the diuretic (randomized, double-blind study) for episodes of significant ST-D (> or = 0.1 mV, duration > or = 1 min, interval > or = 1 min). The reduction in office BP and daytime ambulatory BP was similar for both agents, as was a significant reduction in the heart rate x systolic BP product (DP) over 24 h (felodipine: 12,441 +/- 2076 vs 11,643 +/- 1953 mmHg.min-1; P = 0.048; diuretic: 12,366 +/- 2782 vs 11,062 +/- 2012 mmHg.min-1; P = 0.003). While felodipine significantly decreased the total number of ST-D (from 40 to six episodes; P = 0.03), the total number of ST-D remained unchanged with the diuretic (non-significant increase from 31 to 45 episodes; P = 0.24). The same trend was observed for the number of patients with ST-D.(ABSTRACT TRUNCATED AT 250 WORDS)

[Cardiovascular risk factors in patients over 65-years of age in Germany. Results of the STEPHY Study (Starnberg Trial on Epidemiology of Parkinsonism and Hypertension in the Elderly)]

The aim of the study was to assess the current cardiovascular risk factor profile including data on treatment of a representative population over the age of 65 in Germany. From a total of 1190 inhabitants > or = 65 years living in two Bavarian villages near Munich, 982 could be visited at home ("door-to-door" survey), where a questionnaire and the measurement section were performed (response rate 82.5%). Blood pressure was measured three times in the sitting position with a standard sphygmomanometer, ("actual") hypertension was defined as systolic blood pressure > or = 160 mm Hg and/or diastolic blood pressure > or = 95 mm Hg or effective antihypertensive treatment. Obesity was defined as body mass index > or = 27.8 kg/m2 for men or > or = 27.3 kg/m2 for women, hypercholesterolemia as total cholesterol > or = 250 mg/dl (6.5 mmol/l), diabetes as fasting serum glucose > 120 mg/dl, glucosuria or treatment with insulin or oral antidiabetics. With a prevalence of 53% hypertension was the leading risk factor, followed by obesity with 35% and hypercholesterolemia with 21%; smoking and diabetes were observed in < 10%. Hypertension and obesity tended to be more prevalent in women, diabetes in men; hypercholesterolemia was significantly more prevalent in women. While the prevalence of hypertension increased up to the age groups "75-79 years" in men and "80-84 years" in women, there was a constant decrease with age for obesity, hypercholesterolemia and smoking. Three-quarters of the participants showed a minimum of one cardiovascular risk factor, the risk factor combination "hypertension/hypercholesterolemia/smoking" was observed however only in 1%.(ABSTRACT TRUNCATED AT 250 WORDS)

Prevalence, awareness, treatment and control of hypertension in a population over the age of 65 years: results from the Starnberg Study on Epidemiology of Parkinsonism and Hypertension in the Elderly (STEPHY)

OBJECTIVE

To assess the prevalence of hypertension and isolated systolic hypertension and the level of awareness, treatment and control of hypertension, in a population aged over 65 years.

DESIGN

Cross-sectional survey of the total population aged > or = 65 years of two Bavarian villages with a representative age distribution.

PATIENTS

From a total of 1190 inhabitants aged > or = 65 years, 982 (394 male, 588 female) participated (response rate 82.5%).

METHODS

All of the participants were visited at home by physician observers. After a standardized questionnaire, blood pressure was measured three times on one occasion with the subject in the sitting position, using a standard mercury sphygmomanometer. 'Actual' hypertension was defined as systolic blood pressure (SBP) > or = 160 or diastolic blood pressure (DBP) > or = 95 mmHg, or both, or current use of antihypertensive drugs given for the indication hypertension in patients with blood pressure < 160/95 mmHg. Isolated systolic hypertension was defined as SBP > or = 160 and DBP < 90 mmHg. All 'actual' hypertensives were further classified as 'unaware' of hypertension, 'aware' (but not treated), 'treated' (current use of antihypertensive drugs for the indication hypertension and blood pressure > or = 160/95 mmHg) or 'controlled' (treated and blood pressure < 160/95 mmHg).

RESULTS

Mean +/- SD blood pressure was 154.5 +/- 24.4/84.9 +/- 11.6 mmHg (when 52 institutionalized participants were excluded, 155.6 +/- 24.4/85.3 +/- 11.6 mmHg). The SBP was significantly higher in females than in males and increased up to the age group 80-84 years both in males and in females. The DBP decreased with age. The prevalence of 'actual' hypertension was 53% and increased up to the age group 75-79 years in males and 80-84 years in females. The prevalence of isolated systolic hypertension was 17% (with patients currently using antihypertensive drugs excluded). Of the patients with 'actual' hypertension, 34% were 'unaware' of the diagnosis, 12% 'aware', 32% 'treated' and 22% 'controlled'.

CONCLUSIONS

In central Europe hypertension, with a prevalence of > 50%, remains the most common cardiovascular risk factor in the elderly. Although most elderly hypertensives are currently treated with antihypertensive agents, less than one-quarter are controlled, and more than one-third are still unaware of the diagnosis. These levels of awareness and control call for better strategies in the diagnosis and treatment of hypertension in the elderly.

"White coat" hypertension and alerting reaction in elderly and very elderly hypertensive patients

"White coat" hypertension can be demonstrated in 20-25% of younger patients with mild-to-moderate hypertension. In a population of 50 untreated hypertensive patients > or = 70 years (mean age 79 +/- 6 years, office blood pressure > or = 160 mmHg systolic and > or = 95 mmHg diastolic) ambulatory blood pressure monitoring, ECG and echocardiography were performed to assess the frequency of "white coat" hypertension and the alerting reaction ("white coat" effect). "White coat" hypertension was diagnosed, if mean daytime ambulatory blood pressure was < or = 146/87 mmHg (taken as upper "normal" limit), "definite" hypertension, if > 146/87 mmHg. Nine patients (18%) were classified as "white coat", 28(56%) as "definite" hypertensives, 13(26%) as an "intermediate" group. There were no differences in gender, weight, concomitant diseases, pre-study treatment, and systolic or diastolic left ventricular function between the groups. Patients with "white coat" hypertension showed lower office blood pressure (178 +/- 13/98 +/- 3 vs 201 +/- 19/104 +/- 7 mmHg; p < 0.004), lower left ventricular mass index (131 +/- 9 vs 139 +/- 26 g/m2, p < 0.5), no left ventricular hypertrophy (ECG-criteria; p < 0.05), a more pronounced alerting reaction (39 +/- 13/22 +/- 5 vs 27 +/- 17/8 +/- 9; p < 0.01) and no correlation between office blood pressure and left ventricular mass compared to the "definite" hypertension group. The total group showed an average alerting reaction of 30 +/- 19/12 +/- 8 mmHg. It is concluded that "white coat" hypertension and an alerting reaction can be demonstrated in untreated elderly and very elderly hypertensive patients. Patients with "white coat" hypertension are characterized by a milder degree of hypertension, less cardiac target organ damage and a more pronounced alerting reaction. The prognostic significance of "white coat" hypertension in the elderly needs to be reevaluated in a larger population.

Usefulness of simultaneous ambulatory electrocardiographic and blood pressure monitoring in detecting myocardial ischemia in patients > 70 years of age with systemic hypertension

Ischemic-type ST-segment depression is frequently observed in younger hypertensive patients. To assess the frequency of ST-segment depression in elderly hypertensive patients and to determine the influence of heart rate (HR) and blood pressure (BP) on the episodes of transient myocardial ischemia, ambulatory electrocardiographic and BP monitoring was simultaneously performed in 41 untreated hypertensive patients > 70 years of age (mean age 79 +/- 6 years; office BP > or = 160/95 mm Hg). A total of 66 episodes of significant ST-segment depression (> or = 0.1 mV, duration > or = 1 minute, interval > or = 1 minute) could be demonstrated in 15 patients (37%); 26 patients (63%) had no ST-segment changes. The 2 groups did not differ in age, gender, office or ambulatory BP, diurnal BP profile, concomitant diseases, ventricular arrhythmias, or in left ventricular (LV) mass or function. In 11 patients with ST-segment depression (73%), an increase in HR of > 15% preceded the episodes of ST-segment depression; 2 of these patients (13%) had an additional increase in BP of > 20/10 mm Hg. The extent of ST-segment depression was correlated significantly to BP, HR and HR x systolic BP product during the ischemic events, to office BP, and to LV mass. In conclusion, transient myocardial ischemia is a frequent phenomenon in elderly hypertensive patients with and without LV hypertrophy. Whereas most episodes of ischemia are preceded by an increase in HR, the extent of ST-segment depression is dependent on HR, BP and LV mass.

[Orthostatic hypotension with syncope--a problem of hypertensive therapy in the aged]

In 12 of 32 elderly (> 65 years) hypertensives admitted with syncope, a diagnosis of orthostatic hypotension was made after a positive orthostatic tolerance test and extensive diagnostic evaluation with exclusion of other causes of syncope. Blood pressure of these 12 patients (pts.) after admission was 145 +/- 16/83 +/- 6 mmHg; at that time the pts. were treated with 2.6 +/- 1.6 different antihypertensive agents, and 67% of the pts. received a combination therapy. After reevaluation of treatment the pts. could be discharged with 1.3 +/- 0.7 different antihypertensive agents (significant difference, p < 0.02); in 25% of pts. (p < 0.05) combination therapy was still necessary. Before discharge casual blood pressure was 156 +/- 17/85 +/- mmHg (with the patient in the sitting position); average daytime ambulatory blood pressure was 145 +/- 18/80 +/- 5 mmHg. Three months after discharge 91% of pts. remained free of a new syncope. Orthostatic hypotension is a frequent cause of syncope in the hypertensive elderly; thus, their blood pressure should be checked more often in the sitting and standing position and by ambulatory monitoring.

Three cases of malignant neoplasm, pneumonitis, and pancytopenia during treatment with low-dose methotrexate

A 77-year-old man with chronic obstructive pulmonary disease was treated with low-dose methotrexate (7.5-15 mg per week). After 15 months a diagnosis of urothelial carcinoma of the bladder was made; after a further 6 months pneumonitis and pancytopenia developed. The patient died due to massive pulmonary hemorrhage. A malignant teratoma was diagnosed in a 65-year-old asthmatic man 16 months after initiation of methotrexate therapy (15 mg per week). The patient died 4 months later due to fulminant progression of the neoplasm. A third malignant neoplasm (dermal squamous cell carcinoma) was seen in a 64-year-old woman with rheumatoid arthritis after 13 months treatment with 7.5 mg methotrexate per week. These three cases, while obviously not proving a causal relationship between long-term treatment with low-dose methotrexate and development of malignant neoplasm, do call for stringent treatment criteria, close surveillance, and prospective studies.

Toxoplasmosis with early intracerebral hemorrhage in a patient with the acquired immunodeficiency syndrome

Cerebral hemorrhage is a rare complication of the acquired immunodeficiency syndrome. We report a case of multifocal hemorrhage in a 37-year-old homosexual man with cerebral toxoplasmosis. Histopathologic examination, performed at cerebral autopsy, confirmed the findings on CT and MRI.

Sarcoidosis and immunocytoma

The current literature contains reports of sarcoidosis with polyclonal increases in immunoglobulins. There are also reports of lymphoma in patients with pre-existing sarcoidosis. This is believed to be the first report of a patient in whom a monoclonal IgM kappa paraproteinemia developed after the diagnosis of sarcoidosis. This paraproteinemia was linked with a histologically proved non-Hodgkin's lymphoma. The possible relationships between the two disease entities are discussed.

[Chronic thallium poisoning. Study of criminal poisoning]

In a 42-year-old man with abdominal symptoms, loss of hair and increasing distal polyneuropathy in both legs, the clinical suspicion of thallium poisoning was confirmed by urinary and blood analysis. Hair analysis provided a pointer to the time of poisoning. In addition to symptomatic measures, treatment consisted of administration of potassium-iron (III) hexacyanoferrate (II) (Berlin blue), combined with forced diuresis. Despite the overall favourable course, residual symptoms of distal polyneuropathy were still present 6 months after discharge from hospital.

[Comparison of diflunisal and tilidine in tumor pain]

In an open study in patients with tumour-induced pain the analgetic effects of the prostaglandin-inhibiting compound diflunisal and the centrally-acting analgetic tilidine N were compared. A dosage of 1 g diflunisal was found to be equivalent to 50 drops of tilidine N and to be subjectively well-tolerated. In the pain-relieving therapy of tumour patients diflunisal appears to offer a genuine alternative to centrally-acting analgetics.

[Local anesthesia and beta receptor blockers in dentistry. (Study on an injectable combination of lidocaine and betadrenol)]

A double blind trial was undertaken to determine whether the addition of the beta-receptor blocker Betadrenol in two different doses to a lidocaine solution containing adrenaline could influence the exogenous and endogenous beta-adrenergic effects in the field of dental interventions under local anesthesia. It could be shown that already very small amounts of the beta-receptor blocker Betadrenol could suspend beta-adrenergic stimulation of the heart and so prevent unwanted circulatory reactions without side effects on the central nervous system.

Side effects and contraindications of beta-receptor blocking agents

Unwanted effects of beta-receptor blocking agents can be divided into three categories: 1. Those arising specifically from the pharmacologic, i.e., beta-blocking action. 2. Side effects not directly (or not with certainty) related to beta-blockade. 3. Adverse and potentially specific reactions to individual beta-blocking agents. Category 1 covers the majority of adverse effects (heart failure, severe bradycardia and hypotension, arterial insufficiency, increased airways resistance, gastrointestinal symptoms, hypoglycemia). These can largely be avoided by proper selection and preparation of patients. Category 2 covers cutaneous reactions (rashes, alopecia, pruritus), purpura (thrombocytopenic and nonthrombocytopenic) etc. as well as side effects attributable to the central nervous system (antianxiety effects, nightmares etc.). In the third category the "oculo-cutaneous syndrome" associated with practolol is discussed.
