Anterior-wall and non-anterior-wall STEMIs do not differ in long-term mortality: results from the augsburg myocardial infarction registry.

Background: Different ST-segment elevation myocardial infarction (STEMI) localizations go along with dissimilarities in the size of the affected myocardium, the causing coronary vessel occlusion, and the right ventricular participation. Therefore, this study aims to clarify if there is any difference in long-term survival between anterior- and non-anterior-wall STEMI. Methods: This study included 2,195 incident STEMI cases that occurred between 2009 and 2017, recorded by the population-based Augsburg Myocardial Infarction Registry, Germany. The study population comprised 1.570 men and 625 women aged 25-84 years at acute myocardial infarction. The patients were observed from the day of their first acute event with an average follow-up period of 4.3 years, (standard deviation: 3.0). Survival analyses and multivariable Cox regression analyses were performed to examine the association between infarction localizations and long-term all-cause mortality. Results: Of the 2,195 patients, 1,118 had an anterior (AWS)- and 1,077 a non-anterior-wall-STEMI (NAWS). No significant associations of the STEMI localization with long-term mortality were found. When comparing AWS with NAWS, a hazard ratio of 0.91 [95% confidence interval: 0.75-1.10] could be calculated after multivariable adjustment. In contrast to NAWS, AWS was associated with a greater <28 day mortality, less current or former smoking and higher creatine kinase-myocardial band levels (CK-MB) and went along with a higher frequency of impaired left ventricular ejection fraction (<30%). Conclusions: Despite pathophysiological differences between AWS and NAWS, and identified differences in multiple clinical characteristics, no significant differences in long-term mortality between both groups were observed.

Inflammatory plasma proteins predict short-term mortality in patients with an acute myocardial infarction.

BACKGROUND: The aim of this study was to investigate the association between inflammatory markers and 28-day mortality in patients with ST-elevation myocardial infarction (STEMI). METHODS: In 398 STEMI patients recorded between 2009 and 2013 by the population-based Myocardial Infarction Registry Augsburg, 92 protein biomarkers were measured in admission arterial blood samples using the OLINK inflammatory panel. In multivariable-adjusted logistic regression models, the association between each marker and 28-day mortality was investigated. The values of the biomarkers most significantly associated with mortality were standardized and summarized to obtain a prediction score for 28-day mortality. The predictive ability of this biomarker score was compared to the established GRACE score using ROC analysis. Finally, a combined total score was generated by adding the standardized biomarker score to the standardized GRACE score. RESULTS: The markers IL-6, IL-8, IL-10, FGF-21, FGF-23, ST1A1, MCP-1, 4E-BP1, and CST5 were most significantly associated with 28-day mortality, each with FDR-adjusted (false discovery rate adjusted) p-values of < 0.01 in the multivariable logistic regression model. In a ROC analysis, the biomarker score and the GRACE score showed comparable predictive ability for 28-day mortality (biomarker score AUC: 0.7859 [CI: 0.6735-0.89], GRACE score AUC: 0.7961 [CI: 0.6965-0.8802]). By combining the biomarker score and the Grace score, the predictive ability improved with an AUC of 0.8305 [CI: 0.7269-0.9187]. A continuous Net Reclassification Improvement (cNRI) of 0.566 (CI: 0.192-0.94, p-value: 0.003) and an Integrated Discrimination Improvement (IDI) of 0.083 ((CI: 0.016-0.149, p-value: 0.015) confirmed the superiority of the combined score over the GARCE score. CONCLUSIONS: Inflammatory biomarkers may play a significant role in the pathophysiology of acute myocardial infarction (AMI) and AMI-related mortality and might be a promising starting point for personalized medicine, which aims to provide each patient with tailored therapy.

Physical activity, muscular strength, and polypharmacy among older multimorbid persons: Results from the KORA-Age study.

The purpose of this study was to examine whether physical activity (PA) and muscular strength (MS) are related to polypharmacy. Our cross-sectional analysis was based on 711 patients with multimorbidity (MMB), aged 65-94 years, who participated in the KORA-Age study. Participants underwent a face-to-face interview and extensive physical examinations including anthropometric measurements, registration of chronic diseases, determination of health-related behaviors (smoking, alcohol intake, physical activity, etc.), collection of blood samples and measurement of hand-grip strength. PPha was defined as the use of >4 drugs and MMB as having ≥2 of 13 chronic diseases. Prevalence of PPha was 44.6% (n=317), and a significant difference was found in the number of drugs used between participants with and without PPha (7.2±2.1 vs 2.5±1.2, P<.001). Patients in the lower compared to the upper tertile of physical activity had a significantly increased odds to be on PPha (OR: 1.64, 95% CI: 1.05-2.56, P=.031) after controlling for age, gender, BMI, family status, education, alcohol intake, smoking habits, number of diseases, hs-CRP, and telomere length. On the contrary, no significant association between muscular strength and PPha was found (OR: 1.04, 95% CI: 0.66-1.63, P=.873) after multivariable adjustment. Among older persons with MMB, lower levels of physical activity, but not low muscular strength, are associated with higher odds of PPha. Increasing the levels of physical activity appears to be highly recommended in order to potentially reduce the risk of PPha among multimorbid persons aged 65 and older.

Low serum omentin levels in the elderly population with Type 2 diabetes and polyneuropathy.

AIMS: To investigate the hypothesis that high serum levels of omentin, an adipokine with anti-inflammatory, insulin-sensitizing and cardioprotective properties, may be related to a lower risk of diabetic sensorimotor polyneuropathy. METHODS: The association between serum omentin level and polyneuropathy was estimated in people aged 61-82 years with Type 2 diabetes (47 with and 168 without polyneuropathy) from the population-based KORA F4 study. The presence of clinical diabetic sensorimotor polyneuropathy was defined as bilateral impairment of foot vibration perception and/or foot pressure sensation. Omentin levels were determined by enzyme-linked immunosorbent assay. RESULTS: Serum omentin level was inversely associated with polyneuropathy after adjustment for age, sex, height, waist circumference, hypertension, total cholesterol, smoking, alcohol intake and physical activity [odds ratio 0.45 (95% CI 0.21-0.98); P = 0.043]. Although omentin was positively correlated with adiponectin (r = 0.55, P < 0.0001) and inversely with tumour necrosis factor-α (r = -0.30, P = 0.019), additional adjustment for adiponectin and tumour necrosis factor-α had little impact on the association. CONCLUSIONS: Serum levels of omentin are reduced in people with Type 2 diabetes and diabetic sensorimotor polyneuropathy, independently of established risk factors of polyneuropathy. This association is only partially explained by biomarkers of subclinical inflammation.

Association between muscular strength and inflammatory markers among elderly persons with cardiac disease: results from the KORA-Age study.

Little is known about the association between muscle strength and inflammation in diseased individuals and particularly in cardiac patients. Thus, our purpose was to examine the association of muscular strength with the inflammatory status in older adults with and without cardiac disease. The cross-sectional analysis was based on 1079 adults aged 65-94 years, who participated in the KORA-Age study. Participants underwent an interview and extensive physical examinations including anthropometric measurements, registration of diseases and drug intake, determination of health-related behaviors, collection of blood samples for measurements of interleukin-6 and hs-CRP and muscle strength measurement using hand-grip dynamometry. Cardiac patients (n = 323) had higher levels of IL-6 and poorer muscle strength compared with older adults without cardiac disease. Among persons with cardiac diseases, muscle strength in the lower tertile compared to the upper tertile was significantly associated with increased odds of having elevated IL-6 levels (OR 3.53, 95 % CI 1.18-10.50, p = 0.024) after controlling for age, gender, body fat, alcohol intake, smoking status, diseases, medications and physical activity, whereas the association between muscle strength and hs-CRP remained borderline significant (OR 2.80, 95 % CI 0.85-9.24, p = 0.092). The same trends, with slightly lower odds ratios, were also observed in older adults without cardiac disease. Lower levels of muscular strength are associated with higher concentrations of IL-6 and hs-CRP in elderly individuals with and without cardiac disease suggesting a significant contribution of the muscular system in reducing low-grade inflammation that accompanies cardiac disease and aging.

A clinical screening score for diabetic polyneuropathy: KORA F4 and AusDiab studies.

AIMS: Since screening for distal sensorimotor polyneuropathy (DSPN) in individuals with diabetes is being underused, our aim was to develop a clinical screening score for identifying individuals with DSPN. METHODS: All participants with type 2 diabetes and aged 61-82 years from the German population-based KORA F4 Study (n=177) and the Australian population-based AusDiab Study (n=244) were combined into one study sample. Risk indicators of DSPN were identified and entered into a stepwise model-selection procedure, constructing two consecutive scores with increasing complexity (a base and clinical model). RESULTS: The prevalence of DSPN was 18.2% (95% confidence interval (CI): 14.7-22.3). The base model comprised age (years), height (cm), weight (kg), pain or discomfort in the feet and/or legs (yes/no), and duration of diabetes (years), yielding an area under the receiver operating characteristics curve (AUC) of 0.80 (95% CI: 0.76-0.85). The clinical model additionally included diastolic blood pressure (mmHg) and serum creatinine levels (mmol/l). The AUC increased only marginally to 0.82 (0.77-0.87) (p for AUC comparison=0.188). The internal validation of the scores produced similar AUCs. CONCLUSIONS: The screening scores developed in this study are a simple tool to differentiate between a high and low likelihood of having DSPN among individuals with type 2 diabetes.

The use of dietary supplements among older persons in southern Germany - results from the KORA-age study.

OBJECTIVES: Current population-based surveys in Europe on the prevalence of dietary supplement (DS) use in older individuals are scarce. The aim of the present study was to investigate patterns, prevalence and determinants of non-herbal DS use in aged subjects. Furthermore, the intake amounts of vitamins and minerals from supplements were assessed. DESIGN: Cross-sectional. SETTING: Data on supplement use were available from an age- and sex-stratified random sample of the German population-based KORA (Cooperative Health Research in the Region of Augsburg)-Age study. PARTICIPANTS: 1,079 persons who were born in or before the year 1943. MEASUREMENTS: Use of dietary supplements and medications during the last seven days was recorded in a face-to-face interview in 2009. Participants were asked to bring all packages of ingested preparations to the study center. Not only vitamin/mineral supplements, but also non-vitamin non-mineral non-herbal supplements and drugs containing vitamins and minerals were coded as DS. RESULTS: The age-standardized prevalence of DS intake was 54.3% in women and 33.8% in men, respectively. The most commonly supplemented mineral and vitamin, respectively, was magnesium (31.9%) and vitamin D (21.5%) in women and magnesium (18.0%) and vitamin E (12.0%) in men. The highest intakes, compared to the German Dietary Reference Intakes, were reported for biotin, vitamin B6 and B1. Excessive intakes (equal or above the European Tolerable Upper Intake Levels (UL)) were observed especially for magnesium and vitamin E. 20.2% of the women and 32.5% of the men who took magnesium supplements regularly exceeded the UL for magnesium. In case of vitamin E this was true for 8.0% of the women and 13.6% of the men. Determinants of DS use were sex, education, smoking, physical activity, neurological diseases, and stroke. CONCLUSION: A high proportion of the general population aged 65 years and older in Southern Germany uses DS, especially supplements containing vitamins/minerals. The supplementation of vitamin D can be regarded as favorable in this age group, whereas the excessive intakes of vitamin E might be a cause of concern.

[TSH-reference range of adults: results from the population-based study KORA F4]. / TSH-Referenzbereich bei süddeutschen Erwachsenen: Ergebnisse aus der bevölkerungsbasierten KORA F4-Studie.

INTRODUCTION: There is no valid nationwide reference value for Thyroid-stimulating hormone (TSH) for German adults because of different iodine supply and different laboratory equipment, however, reference values for single regions of Germany have been defined. The aim of this study was to find a reference value for South Germany and to compare this with results of other population-based studies. METHODS: 3080 individuals from the KORA-F4 study (Cooperative Health Research in the Region of Augsburg) at the age range of 32 to 81 years were examined regarding their thyroid characteristics (anamnesis, sonography and clinical chemistry). After excluding individuals with known as well as unknown thyroid disorders revealed by the KORA study, there were 710 thyroid-healthy individuals left to evaluate TSH-, fT3- and fT4-reference ranges. RESULTS: For thyroid-healthy men and women we evaluated a TSH-reference range of 0.52-3.60 mIU/l on Siemens Vista Analysers with a median of 1.49 mIU/l. We could not find any statistically significant influence of age or sex. Median iodine excretion in urine was 118.6 µg/g creatinine in our healthy population which is above the recommended target value of 100 µg/g. DISCUSSION: The TSH-reference value of the South German population is higher than the one assessed in the Northeast-German SHIP-study 10 years ago. For the definition of a TSH-reference value, population-based and apparatus-specific examinations are necessary.

Patient-reported symptoms in acute myocardial infarction: differences related to ST-segment elevation: the MONICA/KORA Myocardial Infarction Registry.

OBJECTIVES: The early recognition of symptoms of myocardial infarction (MI) is crucial for patients with both ST-segment elevation (STEMI) and non-STEMI (NSTEMI). However, to date, only a few studies have examined the differences between patients with STEMI and NSTEMI with regard to the range of presenting MI symptoms. DESIGN: The study population comprised 889 individuals with STEMI and 1268 with NSTEMI, aged 25-74, hospitalized with a first-time MI between January 2001 and December 2006 recruited from a population-based MI registry. The occurrence of 13 symptoms was recorded during a standardized patient interview. RESULTS: Patients with STEMI were significantly younger, more likely to be smokers and less likely to have a history of hypertension or sleep disturbances prior to the acute MI (AMI) event than those with NSTEMI. A total of 50% of the patients attributed their experienced symptoms to the heart. Logistic regression modelling revealed that patients with STEMI were significantly more likely than patients with NSTEMI to complain of vomiting [odds ratio (OR) 2.34, 95% confidence interval (CI) 1.76-3.05], dizziness (OR 1.63, 95% CI 1.30-2.03) and diaphoresis (OR 1.49, 95% CI 1.23-1.81). Furthermore, patients with STEMI were less likely to experience dyspnoea (OR 0.81, 95% CI 0.68-0.98) or pain in the throat/jaw (OR 0.80, 95% CI 0.66-0.98). CONCLUSIONS: Only half of all patients correctly attributed their symptoms to the heart. Patients with STEMI and NSTEMI showed differences regarding several presenting symptoms. Further research is needed to replicate our results, and public awareness of AMI symptoms needs to be improved.

Prediction models for incident type 2 diabetes mellitusin the older population: KORA S4/F4 cohort study.

BACKGROUND: The aim was to derive Type 2 diabetes prediction models for the older population and to check to what degree addition of 2-h glucose measurements (oral glucose tolerance test) and biomarkers improves the predictive power of risk scores which are based on non-biochemical as well as conventional clinical parameters. METHODS: Oral glucose tolerance tests were carried out in a population-based sample of 1353 subjects, aged 55-74 years (62% response) in Augsburg (Southern Germany) from 1999 to 2001. The cohort was reinvestigated in 2006-2008. Of those individuals without diabetes at baseline, 887 (74%) participated in the follow-up. Ninety-three (10.5%) validated diabetes cases occurred during the follow-up. In logistic regression analyses for model 1, variables were selected from personal characteristics and additional variables were selected from routinely measurable blood parameters (model 2) and from 2-h glucose, adiponectin, insulin and homeostasis model assessment of insulin resistance (HOMA-IR) (model 3). RESULTS: Age, sex, BMI, parental diabetes, smoking and hypertension were selected for model 1. Model 2 additionally included fasting glucose, HbA(1c) and uric acid. The same variables plus 2-h glucose were selected for model 3. The area under the receiver operating characteristic curve significantly increased from 0.763 (model 1) to 0.844 (model 2) and 0.886 (model 3) (P<0.01). Biomarkers such as adiponectin and insulin did not improve the predictive abilities of models 2 and 3. Cross-validation and bootstrap-corrected model performance indicated high internal validity. CONCLUSIONS: This longitudinal study in an older population provides models to predict the future risk of Type 2 diabetes. The OGTT, but not biomarkers, improved discrimination of incident diabetes.

Incidence of Type 2 diabetes in the elderly German population and the effect of clinical and lifestyle risk factors: KORA S4/F4 cohort study.

AIMS: To determine the incidence of Type 2 diabetes in an elderly population in Germany and its association with clinical and lifestyle factors. METHODS: Oral glucose tolerance tests (OGTT, World Health Organization criteria) were carried out in a random sample of 1353 subjects (age group 55-74 years; 62% response) in Augsburg (Southern Germany) (1999-2001). The cohort was re-investigated in 2006-2008. Of those individuals without diabetes (baseline), 887 (74%) participated in the follow-up. RESULTS: Ninety-three (10.5%) developed diabetes during the 7-year follow-up period {standardized incidence rates [95% confidence interval (CI)] per 1000 person-years: total 15.5; 12.6, 19.1; men 20.2; 15.6, 26.1; women 11.3; 7.9, 16.1}. In both sexes, those who developed diabetes were slightly older, were more obese, had a more adverse metabolic profile (higher glucose values, HbA(1c), fasting insulin, uric acid, and triglycerides) and were more likely to have hypertension at baseline than were participants remaining free of diabetes (P < 0.05). On stepwise logistic regression, age, parental diabetes, body mass index, uric acid, current smoking, HbA(1c) and fasting and 2-h glucose (OGTT) were strong predictors of diabetes incidence. The risk of diabetes was higher in subjects with isolated impaired glucose tolerance (odds ratio 8.8; 95% CI 5.0, 15.6) than in isolated impaired fasting glucose (4.7; 2.2, 10.0), although the difference did not reach statistical significance. CONCLUSIONS: For the first time, we have estimated the incidence of Type 2 diabetes in an elderly German cohort and demonstrated that it is among the highest in Europe. The OGTT appears to be useful in identifying individuals with high Type 2 diabetes risk. Our results support a role of smoking in the progression to diabetes.

The MONICA Augsburg surveys--basis for prospective cohort studies.

As part of the WHO MONICA project three population-representative surveys were conducted in the study region of Augsburg since 1984/85 to describe time trends of classical cardiovascular risk factors. These surveys provide relevant baseline-information for prospective health outcome studies. Three independent study populations were recruited in 1984/85 (S1: age 25 - 64 years), 1989/90 (S2: age 25 - 74 years), and 1994/95 (S3: age 25 - 74 years) by a two-stage cluster sampling, with random sampling for the city of Augsburg, and a random selection of 16 communities by community size in the two adjacent counties. In the three surveys, 13,427 persons have had 13,818 study participations, since some subjects were by chance sampled for more than one survey. From 1984 to 1995, no trends in hypertension could be observed, but an increase of 15 % (men) resp. 30 % (women) in dyslipidaemia (total/HDL cholesterol ratio > or = five). Cigarette smoking decreased in 55 to 64 year old men und increased in 35 to 64-year old women. The predictive impact for incident Acute Myocardial Infarction (AMI) per 100,000 person years is highest for cigarette smoking (men 880, women 360), followed by dyslipidemia (men 739, women 318) and systolic blood pressure > or = 160 mm Hg (men 658, women 276). By 31st December 2002 1,551 persons (1,031 men, 520 women) had died. The surveys will be used for further gender-specific cross-sectional and longitudinal analyses with special focus on classical, new laboratory and genetic risk factors as determinants of mortality, incident AMI and incident type 2 diabetes, to improve preventive strategies.

Type 2 diabetes mellitus in Augsburg--an epidemiological overview.

This article provides an overview of the prevalence of type 2 diabetes and the antidiabetic treatment over a 17 year study period. The causes of the disease and the impact of diabetes on cardiovascular disease (CVD) morbidity are discussed. Furthermore, changes in lifestyle and risk factor profile in persons with diabetes are reported. We present data from the MONICA/KORA surveys S1-S4 conducted between 1984/85 and 1999/2001 in the region of Augsburg, Southern Germany and the Augsburg Myocardial Infarction Registry. Contrary to most studies from other countries, in the 25 to 74 year old Augsburg population the prevalence of known diabetes did not increase over the last years. Obesity and decreased physical activity are the two main lifestyle related risk factors for type 2 diabetes. Recently, further modifiable risk factors such as smoking and hypertension have been associated with the development of type 2 diabetes in the Augsburg population. Consistent with recommendations to intensify glucose control in diabetic persons the diabetes treatment continuously improved during the study period. However, health status of persons with diabetes is far from optimal in the Augsburg population suggesting that recommendations for primary prevention of CVD in diabetic persons were not sufficiently put into practice until 1999/2001. Furthermore, data from the MONICA/KORA Augsburg Myocardial infarction registry underline the challenge that in particular men and women with diabetes should receive intensive preventive interventions proven to reduce CVD risk. In conclusion, data from the MONICA/KORA Augsburg studies suggest that it should become an important public health priority to prevent diabetes mellitus.

Sleep disturbance as a predictor of type 2 diabetes mellitus in men and women from the general population.

AIMS/HYPOTHESIS: To examine gender specific associations between sleep disturbance and incident type 2 diabetes mellitus in a representative population sample in Germany. METHODS: The study was based on 4,140 men and 4,129 women (aged 25-74 years) who participated in one of the three MONICA Augsburg surveys between 1984 and 1995, and who were free of diabetes at baseline. Incident cases of type 2 diabetes were assessed using a follow-up questionnaire in 1998. Gender specific hazard ratios were estimated from Cox proportional hazard models. RESULTS: A total of 119 cases of incident type 2 diabetes among men and 69 among women were registered during the mean follow-up period of 7.5 years. In both sexes, difficulty maintaining sleep was associated with a higher risk of type 2 diabetes. After adjustment for age, survey, hypertension, dyslipidemia, parental history of diabetes, history of angina pectoris, regular smoking, physical activity, alcohol intake, body mass index and education, the hazard ratio in men was 1.60 (95% CI: 1.05-2.45) and the hazard ratio in women was 1.98 (95% CI: 1.20-3.29). In contrast, difficulty initiating sleep was not associated with a significantly increased risk of developing type 2 diabetes mellitus after multivariable adjustment in both sexes in the present study. CONCLUSIONS/INTERPRETATION: Difficulty maintaining sleep was associated with an increased risk of type 2 diabetes in men and women from the general population. Although, the causal pathway is not entirely clear, it seems that both insulin resistance and chronic low-grade systemic inflammation may be involved.

[Clinical wound botulism in injecting drug addicts]. / Klinisk sårbotulisme hos sprøytenarkomane.

Wound botulism among drug abusers was first described in the USA in 1982. From 1988 to 1995, 46 laboratory confirmed cases were reported in California. The condition occurred for the first time in Norway in 1997 when three cases of suspected wound botulism among drug users who injected heroin subcutaneously or intramuscularly were reported. Two of these cases are presented here with neurophysiological findings and differential diagnosis.

Combined intra-arterial chemotherapy followed by radiation in astrocytomas.

Seventy-five patients harboring astrocytomas received 4 cycles of infra-ophthalmic carotid injections of BCNU, combined with vincristine intravenously and procarbazine orally. All of the patients thereafter, received radiation therapy. The five year survival was 73% for all patients. The age of the patients had no significant impact on survival. The treatment results were compared with the results of 57 patients with astrocytomas who were treated with surgery followed by radiation in the same period. These 57 patients had a 5 year survival of 45% with a five year survival in patients < or = 40 years and patients > 40 years of 70% and 22%, respectively (p < 0.05). In multivariate survival analysis of the BCNU group and radiation group together, treatment group and corticosteroid dependency were the only prognostic factors. No leukoencephalopathy was seen during the treatment or in the follow-up of the patients. We conclude that pre-radiation intra-arterial chemotherapy can be given without significant morbidity and produces an improvement in survival in patients older than 40 years.

Asymmetrical autonomic dysfunction of the feet after retroperitoneal surgery in patients with testicular cancer: 2 case reports.

We report on 2 patients with hyperhidrosis and decreased temperature of the leg on the unoperated side after unilateral retroperitoneal lymph node dissection. Both patients had a 4 to 5C difference in skin temperature of the feet, with the operated side being warm and dry compared to the nonoperated side. This condition is most likely due to a lesion of sympathetic fibers or ganglia located in close proximity to the retroperitoneal lymph nodes, resembling a unilateral lumbar sympathectomy. In addition, both patients had profuse sweating and a subjective feeling of coldness of the leg on the nonoperated side, which caused considerable discomfort. This latter phenomenon most likely represents a compensatory sympathetic hyperfunction due to the decreased sympathetic function in the other leg.

Raynaud's phenomenon after combination chemotherapy of testicular cancer, measured by laser Doppler flowmetry. A pilot study.

The pathophysiology of Raynaud's phenomenon after Cisplatin-Bleomycin-Vinblastine combination chemotherapy, its relationship to polyneuropathy, and response to transcutaneous nerve stimulation (TNS), was studied in eight patients previously treated for testicular cancer. Peripheral circulation in the index finger was measured by laser Doppler flowmetry before and after cold provocation. In all patients there was an exaggerated and prolonged vasoconstrictor response to cold, with a mean flux reduction of 61%, and a mean restitution time of greater than 7 min, characteristic of Raynaud's phenomenon of the vasospastic type. The normal controls had a mean flux reduction of 24% and a restitution time of 1.5 min. Clinical examination and nerve conduction measurements revealed a mild polyneuropathy in five of the eight patients, but an etiological relationship with Raynaud's phenomenon could not be ascertained. There was no measurable effect of TNS.

Long-term somatic side-effects and morbidity in testicular cancer patients.

In order to evaluate long-term somatic morbidity after treatment for testicular cancer 149 patients with NED greater than or equal to 3 years answered a questionnaire. The patients had been treated with surgery only (32 patients, radiotherapy only (39 patients), cisplatin-based chemotherapy plus surgery (46 patients) or chemotherapy plus radiotherapy with or without surgery (32 patients). Raynaud-like phenomena were the most frequent side-effect occurring significantly more often after cisplatin-based chemotherapy than after surgery or radiotherapy (33/72 patients versus 5/68 patients). Peripheral sensory 'neuropathy' was reported by 18% of all the patients. Seventeen per cent and 11% complained of pulmonary symptoms and auditory symptoms, respectively. Gastrointestinal side-effects were more frequent after any type of cytotoxic therapy than after surgery only (34/47 patients versus 5/22 patients). Twenty-six patients had fathered children after treatment. About 80% of the patients were in full time wage-earning activity when they answered the questionnaire. In conclusion, 3-7 years after treatment for testicular cancer, 30-50% of the patients had minor somatic complaints whereas serious side-effects seldom occurred.

Reversible oedema and necrosis after irradiation of the brain. Diagnostic procedures and clinical manifestations.

One hundred and twelve patients with primary brain tumour were followed every 3 months during and after brain irradiation and chemotherapy with brain scanning, EEG and neurological examination. Early delayed radiation reactions were seen in 6 patients. The symptoms developed 2-8 months after irradiation and lasted for 2-3 months. Two types of reactions were observed. One mild form appeared after 2-3 months and was characterized by low-attenuated expansive areas within the irradiated volume, without contrast enhancement on CT scan. Severe reactions appeared in some patients after 6 months, with exacerbation of earlier clinical signs and contrast enhancing lesions on CT. Regression of the CT finding was seen after 3 months. Recognition of this syndrome is important, as a new neurosurgical procedure might cause lasting neurological sequelae in patients who otherwise would recover without treatment.
