Background Medical specialists experience high levels of stress. This has an impact on their well-being, but also on quality of their leadership. In the current mixed method study, the feasibility and effectiveness of a course Mindful Leadership on burnout, well-being and leadership skills of medical specialists were evaluated. Methods This is a non-randomized controlled pre-post evaluation using self-report questionnaires administered at 3 months before (control period), start and end of the training (intervention period). Burn-out symptoms, well-being and leadership skills were assessed with self-report questionnaires. Semi-structured interviews were used to qualitatively evaluate barriers and facilitators for completion of the course. Results From September 2014 to June 2016, 52 medical specialists participated in the study. Of these, 48 (92%) completed the course. Compared to the control period, the intervention period resulted in greater reductions of depersonalization (mean difference = − 1.2, p = 0.06), worry (mean difference = − 4.3, p = 0.04) and negative work-home interference (mean difference = − 0.2, p = 0.03), and greater improvements of mindfulness (mean difference = 0.5, p = 0.04), life satisfaction (mean difference = 0.4, p = 0.01) and self-reported ethical leadership (mean difference = 0.1, p = 0.02). Effect sizes were generally small to medium (0.3 to 0.6) and large for life satisfaction (0.8). Appreciation of course elements was a major facilitator and the difficulty of finding time a major barrier for participating. Conclusions A ‘Mindful Leadership’ course was feasible and not only effective in reducing burnout symptoms and improving well-being, but also appeared to have potential for improving leadership skills. Mindful leadership courses could be a valuable part of ongoing professional development programs for medical specialists.

ObjectivesMedical leaders are facing leadership challenges that ask for a leadership style that takes care of both themselves and their coworkers. Mindfulness may support this leadership style. We explored how a ‘Mindful leadership for medical specialists’ course affected medical specialists’ leadership.DesignWe conducted a qualitative study based on in-depth interviews. The grounded theory method was used to analyse the data.SettingA university medical centre in the Netherlands.ParticipantsSeventeen medical specialists (six male) with an average age of 51 years (ranging from 40 to 66 years).InterventionsThe mindful leadership course consisted of 10-weekly 5-hour sessions that focused on cultivating mindfulness and compassion. In addition, sessions included didactic and interactional teaching about leadership theories.ResultsFour categories emerged from the data: (A) Self - Attitude: psychological attitude towards self, (B) Self - Behaviour: behaviour towards self, (C) Other - Attitude: psychological attitude towards others, and (D) Other - Behaviour: behaviour towards others. Themes were defined within these categories: awareness of self, open mind, insight and appreciation of self (A), emotional and cognitive self-regulation, letting go of unhelpful behaviour and developing helpful behaviour (B), differences in attitude to others such as awareness of (impact on) others, keeping an open mind about others, allowing difficult emotions associated with others, appreciating of others (C), and communicating more effectively, providing direction, empowering and caring for others (D).ConclusionsThe results help us understand the core elements of mindful leadership, both with respect to one’s psychological attitude and behaviour towards oneself and others. More research on mindful leadership and the effects on self and others is needed. Mindful leadership courses could be a valuable part of clinical training and might contribute to more sustainable healthcare organisations.

Oxygen insensitivity of carcinoma cells and oxygen sensitivity of non-cancer cells in the histochemical assay of glucose-6-phosphate dehydrogenase (G6PD) enables detection of carcinoma cells in unfixed cell smears or cryostat sections of biopsies. The metabolic background of oxygen insensitivity is still not understood completely. In the present study, rat hepatocytes, rat hepatoma cells (FTO-2B), and human colon carcinoma cells (HT29) were used to elucidate these backgrounds. The residual activity in oxygen was 0%, 55%, and 80% in hepatocytes, hepatoma cells, and colon carcinoma cells, respectively. N-ethylmaleimide (NEM), a blocker of SH-groups, did not affect G6PD activity in both carcinoma cell types but reduced G6PD activity in hepatocytes by 40%. Ultrastructural localization of G6PD activity was exclusively in the cytoplasm of carcinoma cells, but in hepatocytes both in cytoplasm and peroxisomes. NEM abolished peroxisomal G6PD activity only. Histochemical assay of catalase activity demonstrated absence of peroxisomes in both carcinoma cell lines. It is concluded that absence of SH-sensitive G6PD activity in peroxisomes in cancer cells is responsible for the oxygen-insensitivity phenomenon.

The serotonergic hypothesis for depression in Parkinson's disease (PD) states that the reduced cerebral serotonergic activity that occurs in PD constitutes a biological risk factor for depression. The aim of our study was to assess the serotonergic hypothesis of depression in PD patients using an experimental approach. In a double-blind, randomized order, placebo-controlled crossover design, the response on the Profile of Mood States (POMS) questionnaire to acute tryptophan depletion (ATD) was studied in 15 PD nondepressed patients and 15 control subjects, without a prior personal or family history of depression. PD patients had lower (worse) baseline scores on the sadness, fatigue and vigor subscales of the POMS, in both ATD and the placebo condition, but not on the tension and anger subscales. There was however neither a significance between group effect, nor significance within-group effect due to ATD. We could find no evidence of a specific serotonergic vulnerability of PD patients for depression. Therefore, our results do not support the serotonergic hypothesis for depression in PD.

✓✓ Based on the results of thalamotomies described by Hassler in 1970, the authors performed bilateral thalamic highfrequency stimulation (HFS) in three patients with intractable Tourette syndrome (TS). In this report they describe the long-term effects. Three male patients (42, 28, and 45 years of age) had manifested motor and vocal tics since early childhood. The diagnosis of TS was made according to the criteria of the Tourette Syndrome Classification Study Group. Any drug or alternative treatment had been either ineffective or only temporarily effective in all three patients. There was no serious comorbidity. The target for stimulation was chosen at the level of the centromedian nucleus, substantia periventricularis, and nucleus ventrooralis internus. After 2 weeks of test stimulation, the pulse generators were implanted. After a follow-up period of 5 years in the patient in Case 1, 1 year in the patient in Case 2, and 8 months in the patient in Case 3, all major motor and vocal tics had disappeared and no serious complications had occurred. When stimulation was applied at the voltage necessary to achieve an optimal result on the tics, a slight sedative effect was noted in all three patients. In the patients in Cases 1 and 3 there were stimulation-induced changes in sexual behavior. Chronic thalamic HFS may be an effective and safe treatment for medically intractable TS in adult patients. Unwanted stimulation-induced side effects may occur.

Item does not contain fulltext Alzheimer's disease (AD) probably involves several pathobiochemical mechanisms and this may be reflected by changes in different serum components. The present study investigated whether the combined analysis of serum molecules related to different mechanisms improves the discrimination of AD patients from healthy controls. Serum of patients with AD was analyzed for a broad spectrum of marker molecules, including 11 inflammatory proteins, 12 sterol intermediates and phytosterols, 2 brain-specific proteins and 4 constituents involved in homocysteine homeostasis. The serum molecule concentrations were combined in a logistic regression model, using a forward stepwise inclusion mode. The results showed that the combination of interleukin-6 (IL-6) receptor, protein alpha1 fraction, cysteine and cholesterol concentrations improved the discrimination between AD patients and healthy controls compared to the single markers. In conclusion, the results of this study have shown that the complex pathology in AD is reflected in a pattern of altered serum concentrations of several marker molecules related to several pathobiochemical mechanisms.

Summary In principle, enzyme histochemistry should be performed on unfixed tissues and cells to avoid inhibition of enzyme activity by chemical fixation. For EM enzyme histochemistry, unfixed tissue specimens include fresh tissue blocks, non-frozen tissue chopper sections, cryostat sections and cell preparations. Studies on localization of enzyme activity at the ultrastructural level in unfixed specimens, be it fresh or frozen, are reviewed here. Preservation of ultrastructural morphology is discussed with special attention to the effects of freezing. It is concluded that unfixed cryostat sections are the best alternative for EM histochemistry of tissues, when interposing a semipermeable membrane in between cryostat section and gelled incubation medium. It is an adequate method to preserve structural integrity of unfixed tissue on the one hand and to avoid inactivation of the enzyme by chemical fixation on the other. For EM cytochemistry on individual cells, a better preservation of ultrastructure may be obtained because freezing can be avoided, but mild pretreatment with a fixative or detergent may be necessary to permeabilize cellular membranes for demonstration of intracellular enzyme activity.

The prevalence of pulmonary tuberculosis is increasing and is associated with a rise in skeletal tuberculosis. Even after appropriate anti-tuberculosis therapy, reactivation of the infection may occur, even after many years. In this case report we describe a patient who had a reactivation of tuberculosis in the knee after total knee arthroplasty. At the age of 14 years, the patient had isolated tuberculosis arthritis of the left knee. Reactivation occurred after total knee arthroplasty 61 years later, at the age of 75. The patient was treated with a combined therapy; first the joint was irrigated with povidine-iodine and saline solution, and gentamicin beads were left behind. When the cultures revealed Mycobacterium tuberculosis, drug therapy of isoniazid, rifampicin, ethambutol and pyrazinamide was started and was continued for 9 months postoperatively. At a recent follow-up, the patient is doing well, with good range of motion in the knee.

A unilateral facet dislocation noted in a 17-year-old boy after an axial cervical trauma proved to be an incidentally encountered preexisting lesion, most likely originating from a forceps delivery at birth. The surgical treatment initially considered was converted to a conservative approach, with full clinical recovery.

Data on the prevalence and clinical value of primitive reflexes (PRs) in dementia are controversial, mainly due to a lack of standardization of the methods by which these signs are elicited and scored. A standardized protocol was used to investigate eight PRs in 20 patients with Alzheimer's disease (AD), 20 patients with vascular dementia (VD), and 20 control subjects for each group. Both patient groups showed considerably more PRs than the control groups. The prevalence of PRs was related to the severity of dementia. No single reflex or combination of PR pathognomonic for dementia could be distinguished. The PR profile of AD and VD patients were similar.

Discrepancies were examined in diagnostic outcome between a monodisciplinary approach and a multidisciplinary, criteria-based approach in patients referred to a university memory clinic. Of 278 patients not fulfilling dementia criteria, 19 had been previously diagnosed as demented (specificity: 0.93). In 60 of 152 demented patients, dementia had not been diagnosed before (sensitivity: 0.61). Underreporting was frequent for mildly demented patients and for patients with coexisting depressive symptoms. In patients referred by psychiatrists, sensitivity rates for dementia and Alzheimer's disease were low; in patients referred by neurologists, depression often went unreported. Results underscore the need for more frequent use of integrated multidisciplinary services for cognitively disturbed patients.

A large, cross-sectional aging investigation of performance on the Stroop Color-Word Test (SCWT) was carried out. Subjects were 247 volunteers, ages 20–80 in seven age levels. Although all subjects thought themselves to be normal and healthy, a post hoc division could be made on the basis of biological life events (BLE). BLE are mild biological or environmental factors, such as repeated experiences of general anesthesia, that can hamper optimal brain functioning. Apart from the anticipated age effects, performance was poorer in subjects who had experienced one or more BLE: The slowing due to BLE was comparable to the effect of age, especially on the task involving language interference in color-naming. Education had a significant effect on performance: More highly educated subjects performed better than less educated subjects. No sex differences were observed. These findings replicate observations made with other tests in parallel studies. They are also in line with several other studies reporting interactions between the effects of aging and physical fitness. This study questions some of the validity of cognitive aging research, as our data suggest that screening for BLE as age-extrinsic factors in nondiseased subjects can reduce many of the performance deficits usually ascribed to aging per se.

A study was made to determine whether two experienced clinicians elicited and scored primitive reflexes (PR) differently and whether reliability could be improved by standardization. Three studies were carried out, using a protocol for the examination of 14 PR. In the first study with 31 healthy young subjects, two investigators found virtually no difference in the routine neurological examination. However, the interobserver agreement was very poor, indicating the need for a further improvement of the PR protocol. In the second study, 30 neurological patients were examined with an improved, more explicit and standardized protocol, in which the amplitude and the persistence of the reflex were scored separately. Interobserver agreement improved considerably, and was high for amplitude as well as persistence. In the third study, 36 neurological patients were examined twice by one investigator within 2 weeks. Good to excellent intraobserver agreement was found. No pathognomonic or strictly localizing reflex could be distinguished.

There is a need for biomarkers in accessible matrices, such as blood, for the diagnosis of neurodegenerative diseases. The aim of this study was to measure the serum levels of brain-type fatty acid-binding protein (FABP) and heart-type FABP in patients with dementia-involving diseases.Brain- and heart-type FABP were measured in serum samples from patients with either Alzheimer's disease (AD) (n = 31), Parkinson's disease (PD, n = 43), or other cognitive disorders (OCD, n = 42) and in 52 healthy controls. The localization of brain- and heart-type FABP was determined in brain sections by immunohistochemistry.Brain-type FABP levels were elevated in serum of 29%, 35%, and 24% of the patients with AD, PD, and OCD, respectively, and in 2% of the healthy donors. Heart-type FABP serum levels were not different amongst the patient groups. Brain-type and heart-type FABP expression was observed in reactive astrocytes in brain sections of patients with AD.In contrast to heart-type FABP, serum levels of brain-type FABP are elevated in a significant proportion of patients with various neurodegenerative diseases and can therefore have importance for defining subgroups of these patients.

SPECT is one of the most employed techniques in the diagnostic workup of idiopathic Parkinson's disease (IPD). Despite its widespread use, the exact diagnostic accuracy of this technique in parkinsonian syndromes remains controversial.In this study, we investigated the diagnostic accuracy of an initial (123)I-ioflupane (FP-CIT) and/or (123)I-iodobenzamide (IBZM) SPECT to differentiate between IPD and other parkinsonian disorders. 248 patients underwent a SPECT scan because of an as yet unclassified parkinsonian syndrome in our clinic between 2001 and 2006. Gold standard was the clinical diagnosis derived from the latest available clinical record, or, when this was not possible, a new complete physical and neurological examination by a blinded movement disorder specialist neurologist. Mean follow-up between SPECT and the latest clinical information was 18 months (range 3 months to 5 years).223 of the 248 patients were clinically definitely diagnosed after follow-up: IPD 127, atypical parkinsonian syndromes (APS) 27, essential tremor (ET) 22, vascular parkinsonism (VP) 16, drug-induced parkinsonism (DIP) 5, doubt between PD and APS 2, other diseases without dopaminergic involvement 24. The mean odds ratio (95% CI) for FP-CIT SPECT's ability to distinguish between IPD and ET was 82 (11-674); between IPD and VP 61 (8-490); between IPD and DIP 36 (2-697) and between IPD and APS was 1 (0-4). The odds ratio for the IBZM SPECT tracer to differentiate between IPD and APS was 7 (2-17).FP-CIT SPECT is accurate to differentiate patients with IPD from those with ET, and IPD from VP and DIP. The accuracy of both FP-CIT and IBZM SPECT scans to differentiate between IPD and APS is low.

Liver grafts are frequently discarded due to steatosis. Steatotic livers can be classified as suboptimal and deteriorate rapidly during hypothermic static preservation, often resulting in graft nonfunction. Hypothermic machine perfusion (MP) has been introduced for preservation of donor livers instead of cold storage (CS), resulting in superior preservation outcomes. The aim of this study was to compare CS and MP for preservation of the steatotic donor rat liver. Liver steatosis was induced in male Wistar rats by a choline-methionine-deficient diet. After 24 hours hypothermic CS using the University of Wisconsin solution (UW) or MP using UW-Gluconate (UW-G), liver damage (liver enzymes, perfusate flow, and hyaluronic acid clearance) and liver function (bile production, ammonia clearance, urea production, oxygen consumption, adenosine triphosphate [ATP] levels) were assessed in an isolated perfused rat liver model. Furthermore, liver biopsies were visualized by hematoxylin and eosin staining. Animals developed 30 to 60% steatosis. Livers preserved by CS sustained significantly more damage as compared to MP. Bile production, ammonia clearance, urea production, oxygen consumption, and ATP levels were significantly higher after MP as compared to CS. These results were confirmed by histology. In conclusion, MP improves preservation results of the steatotic rat liver, as compared to CS.

Objectives Primitive reflexes (PR) generally disappear early in life but may reappear later, in which case they are often associated with chronic neurological conditions, such as dementia or Parkinson's disease. Studies have shown that the presence of PRs may be indicative of both the severity and rate of progression of these diseases and maybe the result of disinhibition of cortical networks. The association between PRs and cognitive function in usual ageing is unclear. We investigated whether the occurrence, amplitude, and persistence of four nociceptive (glabbelar tap, palmomental, pollicomental, and snout reflexes), three prehensile reflexes (suck, palmar grasp, and rooting), and two other reflexes (mouthopen finger-spread and nuchocephalic reflexes) were related to performance in specific cognitive domains in normal ageing individuals. Methods Four-hundred and seventy normal aging participants (25-82 years) in the Maastricht Aging Study (MAAS), were included in the study. They were neurologically and cognitively screened at baseline and were retested after 3 (only individuals aged 50 years and older at baseline) and 6 years. Results The prevalence of most PRs increased with age: 47% of men aged 25-45 years had at least one PR, compared with 73 % of men aged 65-85 year (p = 0.002). In women these percentages were 51 and 75, respectively (p = 0.008). The prevalence, amplitude, and persistence of PRs were unrelated to cognition at baseline or at the 3- or 6-year follow-up. Conclusions The prevalence of particularly nociceptive reflexes rises substantially with increasing age in normal individuals. However, the presence of PRs cannot be considered to be a marker of cognitive decline in normal aging individuals.

The objective of this study was to evaluate which fusion technique provides the best clinical and radiological outcome for adult low-grade lumbar isthmic spondylolisthesis, and to assess the overall clinical and radiological outcome of each fusion technique. A systematic review was performed. Medline, Embase, Current Contents, and Cochrane databases as well as reference lists of selected articles were searched. Randomised controlled trials (RCTs) were used to evaluate the best treatment; controlled studies and non-controlled studies were used to determine the outcomes after surgery. Two independent reviewers evaluated the studies with the methodological checklists of van Tulder and Jadad for the randomised studies and of Cowley for the non-randomised studies. The search resulted in 684 references and eventually 29 studies met the inclusion criteria, of which eight were RCTs, four were prospective, and 17 were retrospective case series. Ten of the case series did not clearly identify consecutive patient selection. All the eight RCTs evaluated the effect of different techniques of posterolateral fusion (PLF). Evidence was found that the PLF was superior to non-operative treatment (exercise). Circumferential fusion was compared to PLF, but no difference could be found. PLF with or without instrumentation was evaluated in three studies, but no benefits from additional instrumentation were found. Other comparisons within PLF showed no effect of decompression, alternative instrumentation, or bone graft substitute. The 21 case series included 24 patient groups. PLF was used in 15 groups, good or excellent clinical outcome varied from 60 to 98% and fusion rate varied from 81 to 100%. Anterior interbody fusion was used in five groups, good or excellent clinical outcome varied from 85 to 94% and fusion rate varied from 47 to 90%. Posterior interbody fusion was used in two groups, good or excellent clinical outcome was 45% and fusion rate was 80 and 95%, respectively. Reduction, loss of reduction, and lordotic angles before and after the treatment was reported in only four studies. Average reduction achieved was 12.3%, average loss of reduction at follow-up was 5.9%. Preoperative lordotic angles were too heterogeneous to pool the results. Adjacent segment degeneration was not reported in any of the publications. A wide variety of complications were reported in 18 studies and included neurological complications, instrument failure, and infections. Fusion for low-grade isthmic spondylolisthesis has better outcomes than non-operative treatment. The current study could not identify the best surgical technique (PLF, PLIF, ALIF, instrumentation) to perform the fusion. However, instrumentation and/or decompression may play a beneficial role in the modern practice of reduction and fusion for low-grade isthmic spondylolisthesis, but there are no studies yet available to confirm this. The outcomes of fusion are generally good, but reports vary widely.

Contains fulltext : 47726.pdf (Publisher’s version ) (Closed access) Elevated serum homocysteine has been associated with increased risk of Alzheimer's disease. Furthermore, elevated homocysteine levels are related to cognitive dysfunction in the elderly. The aim of the present study was to explore the disease specificity of the relation between serum total homocysteine levels and cognitive function. For this, we summarize data from several studies on homocysteine levels in both normal and pathological conditions performed in our laboratories and evaluate possible mechanisms of effects of elevated homocysteine levels in the central nervous system. Total homocysteine levels were measured in serum of: 1) healthy aging individuals; 2) patients with Alzheimer's and Parkinson's disease and patients with other cognitive disorders; and 3) patients with multiple sclerosis. Increased serum homocysteine concentration was related to worse cognitive performance over a 6-year period in the normal aging population (r=-0.36 to -0.14, p

Data on the relationship between idiopathic Parkinson's disease (IPD) and stroke are conflicting. In this study, we examined the frequency of IPD in stroke patients registered in the Maastricht Stroke Registry. With the use of three different search strategies, we found eight individuals with IPD amongst a total of 1,516 stroke patients. We had expected to find approximately 30 IPD patients (relative risk 0.27; 95% confidence interval 0.11–0.53), based on IPD prevalence figures from a Dutch population-based study. We speculate that dopamine deficiency may protect against ischaemic brain damage, perhaps by reducing the effects of excitotoxicity. Mov. Disord. 16:119–123, 2001. © 2001 Movement Disorder Society.

To evaluate whether the Waterlow pressure sore risk (PSR) scale has prognostic significance for intensive care patients. A prospective study. The surgical intensive care unit (ICU) of the University Hospital Rotterdam. Data were evaluated from 594 patients who had been admitted to the ICU during the year 1994. Each patient was assessed daily with respect to their Waterlow PSR score and the development of pressure sores in the sacral region. Actuarial statistical methods were used to analyse the predictive value of the risk score. When a patient had a Waterlow PSR score a25 on admission, the risk of developing a pressure sore was significantly increased compared to patients with a PSR score>25. After admission, the daily Waterlow PSR scores obtained were significantly associated with the risk of developing a pressure sore. For each additional point this risk increased by 23 % (95 % confidence interval 17 to 28%). The Waterlow PSR scale provides the medical and nursing staff at an early stage with reliable information about the risk patients have in developing a pressure sore.

To determine whether psychiatric conditions other than depression are relevant in elder patients with memory disturbances.430 consecutive outpatients (242 males, 188 females; mean age 61.7 years) who visited the Maastricht Memory Clinic were examined, according to a standardised diagnostic procedure, including somatic, neurological, psychiatric and neuropsychological examination. Psychiatric disorders were diagnosed according to DSM-III(-R) criteria.Of 152 patients with dementia, 34 had a secondary depressive syndrome, 19 another secondary psychiatric disorder. Of the 37 patients with a psycho-organic disorder other than dementia, 16 had an organic mood disorder. Of the other 241 patients, 152 had 159 primary psychiatric diagnoses: mood disorders in 100 cases and other psychiatric disorders in 59 cases, especially adjustment disorders, anxiety disorders and personality disorders. Together, only 60% percent of all primary or secondary psychiatric disorders were mood disorders. Various ways in which organic substrate, cognitive problems and psychopathology can be interrelated are discussed.Although affective disorders were the most frequent psychiatric disorders, several other psychiatric conditions were related to memory disturbances as well. Psychiatric assessment in patients with memory complaints should not be restricted to the diagnosis of depressive symptoms.

Eighty subjects participated in a study with five age groups (20, 30, 40, 50, and 60 years). Forty subjects showed evidence of factors related to brain dysfunction (risk factors). Their performance on a Sternberg-type memory scanning task was assessed. Age-related slowing of virtually all aspects of the memory scanning process was observed in the healthy group. However, the effect of the presence of risk factors was larger than that of biological age. The results of the present study make a reasonable case for the view that many age effects reported in the literature can be largely explained by suboptimal brain functioning, i.e., by other factors than aging per se.

The effect of internal drainage after biliary obstruction due to primary cholangiocarcinoma has been studied in seven human liver biopsies with respect to bile pigment accumulation and acid phosphatase activity. Enzyme activity was demonstrated at the light-microscopic level in unfixed cryostat sections using an incubation medium containing naphthol AS-BI phosphate as substrate, and hexazotised pararosaniline as simultaneous coupling agent, and at the ultrastructural level in fixed tissue blocks and chopped tissue sections using sodium beta-glycerophosphate as substrate and lead or cerium ions as capture reagent. Large amounts of bilirubin were found in cryostat sections of non-drained cholestatic livers, especially in pericentral areas. At these sites a high acid phosphatase activity was found. At the ultrastructural level, acid phosphatase activity was found only in the lysosomal compartment--possibly due to the procedure necessary for tissue processing. After internal biliary drainage, the amount of bilirubin diminished, with a concomitant decrease in acid phosphatase activity. The co-localization of accumulations of bile compounds and acid phosphatase activity indicates that lysosomes play a role in the breakdown of bile compounds.

Two patients are described: one with an aneurysm of the infrarenal aorta and common iliac artery that ruptured posteriorly into the iliac vein, the other with an aneurysm of the distal abdominal aorta that ruptured posteriorly into the iliopsoas muscle. Both patients had symptoms compatible with a radicular compression syndrome. Ruptured aneurysm of one of the major abdominal arteries should be considered in the differential diagnosis of affections of the lumbosacral neural outflow, because immediate operation can be life-saving.

— Sixteen patients suffering from spasticity due to multiple sclerosis were treated with baclofen and tizanidine in a partially blind cross-over study. No significant difference in efficacy was found. The most striking difference was seen in the side-effects: baclofen frequently caused more or less severe muscle weakness and even falling during walking and standing. Treatment with tizanidine produced an apparent improvement of mobility in some patients suffering from moderate or marked paresis associated with a marked spasticity of their legs. Isometric muscle strength did not show any significant changes during either treatment. The different impact of baclofen and tizanidine on mobility and weight support seems to be related to their different site of action in spasticity.

A case of tuberculous brain abscess occurred in spite of 4 months' treatment of pulmonary tuberculosis with a triple drug anti-tuberculous regimen. Surgical removal and further chemotherapy were successful.
