Safety of prolonged sacral neuromodulation tined lead testing

OBJECTIVE: Prolonged sacral neuromodulation (SNM) testing is more reliable for accurate patient selection than the usual test period of 4-7 days. However, prolonged testing was suspected to result in a higher complication rate due to infection via the percutaneous passage of the extension wire. Therefore, we prospectively assessed the complications associated with prolonged tined lead testing. PATIENTS AND METHODS: A consecutive series of 44 patients who underwent prolonged tined lead testing for at least 14 days between May 2002 and April 2007 were evaluated. Complications during prolonged tined lead testing, during and after tined lead explantation and during follow-up after implantation of the implantable pulse generator (IPG) were registered prospectively. RESULTS: Four patients suffered from urgency-frequency syndrome, 13 from urge incontinence, 18 from non-obstructive chronic urinary retention and nine from chronic pelvic pain syndrome. The median test phase was 30 days (interquartile range [IQR] 21-36). Thirty-two of the 44 patients (73%) had successful prolonged tined lead testing and 31 of these (97%) underwent the implantation of the IPG. The median follow-up of the IPG implanted patients was 31 months (IQR 20-41). The complication rate was 5% (2/44) during prolonged tined lead testing and 16% (5/31) during follow-up of the IPG implanted patients, respectively. None of the complications could be attributed to prolonged testing. No infections were observed during the study period. CONCLUSIONS: This prospective, observational non-randomised study suggests prolonged SNM tined lead testing is a safe procedure. Based on the low complication rate and the increased reliability for accurate patient selection, this method is proposed as a possible standard test procedure, subject to confirmation by further randomised, controlled clinical studies.

Protocol for a randomized, placebo-controlled, double-blind clinical trial investigating sacral neuromodulation for neurogenic lower urinary tract dysfunction

BACKGROUND Sacral neuromodulation has become a well-established and widely accepted treatment for refractory non-neurogenic lower urinary tract dysfunction, but its value in patients with a neurological cause is unclear. Although there is evidence indicating that sacral neuromodulation may be effective and safe for treating neurogenic lower urinary tract dysfunction, the number of investigated patients is low and there is a lack of randomized controlled trials. METHODS AND DESIGN This study is a prospective, randomized, placebo-controlled, double-blind multicenter trial including 4 sacral neuromodulation referral centers in Switzerland. Patients with refractory neurogenic lower urinary tract dysfunction are enrolled. After minimally invasive bilateral tined lead placement into the sacral foramina S3 and/or S4, patients undergo prolonged sacral neuromodulation testing for 3-6 weeks. In case of successful (defined as improvement of at least 50% in key bladder diary variables (i.e. number of voids and/or number of leakages, post void residual) compared to baseline values) prolonged sacral neuromodulation testing, the neuromodulator is implanted in the upper buttock. After a 2 months post-implantation phase when the neuromodulator is turned ON to optimize the effectiveness of neuromodulation using sub-sensory threshold stimulation, the patients are randomized in a 1:1 allocation in sacral neuromodulation ON or OFF. At the end of the 2 months double-blind sacral neuromodulation phase, the patients have a neuro-urological re-evaluation, unblinding takes place, and the neuromodulator is turned ON in all patients. The primary outcome measure is success of sacral neuromodulation, secondary outcome measures are adverse events, urodynamic parameters, questionnaires, and costs of sacral neuromodulation. DISCUSSION It is of utmost importance to know whether the minimally invasive and completely reversible sacral neuromodulation would be a valuable treatment option for patients with refractory neurogenic lower urinary tract dysfunction. If this type of treatment is effective in the neurological population, it would revolutionize the management of neurogenic lower urinary tract dysfunction.

Inferior Hypogastric Plexus Block Affects Sacral Nerves and the Superior Hypogastric Plexus

Background. The inferior hypogastric plexus mediates pain sensation through the sympathetic chain for the lower abdominal and pelvic viscera and is thought to be a major structure involved in numerous pelvic and perineal pain syndromes and conditions. Objectives. The objective of this study was to demonstrate the structures affected by an inferior hypogastric plexus blockade utilizing the transsacral approach. Study Design. This is an observational study of fresh cadaver subjects. Setting. The cadaver injections and dissections were performed at the Department of Forensic Sciences and Insurance Medicine, Semmelweis University, Budapest, Hungary after obtaining institutional review board approval. Methods. 5 fresh cadavers underwent inferior hypogastric plexus blockade with radiographic contrast and methylene blue dye injection by the transsacral fluoroscopic technique described by Schultz followed by dissection of the pelvic and perineal structures to localize distribution of the indicator dye. Radiographs demonstrating correct needle localization by contrast spread in the specific tissue plane and photographs of the dye distribution after cadaver dissection were recorded for each subject. Results. In all cadavers the dye spread to the posterior surface of the rectum and the superior hypogastric plexus. The dye also demonstrated distribution to the anterior sacral nerve roots of S1, 2, and 3 with bilateral spread in 3 cadavers and ipsilateral spread in 2 of them. Limitations. The small number of cadaver specimens in this study limits the results and generalization of their clinical significance. Conclusions. Inferior hypogastric plexus blockade by a transsacral approach results in distribution of dye to the anterior sacral nerve roots and superior hypogastric plexus as demonstrated by dye spread in freshly dissected cadavers and not by local anesthetic spread to other pelvic and perineal viscera.

The Effects of Postural Loading, Sacral Orientation, and Age on Sex Differences in Lumbar Functional Morphology and Health

A new measure to quantify chest wall deformity in scoliosis patients : does rib hump measurement correlate with anterior chest wall deformity post surgery?

The primary aims of scoliosis surgery are to halt the progression of the deformity, and to reduce its severity (cosmesis). Currently, deformity correction is measured in terms of posterior parameters (Cobb angles and rib hump), even though the cosmetic concern for most patients is anterior chest wall deformity. In this study, we propose a new measure for assessing anterior chest wall deformity and examine the correlation between rib hump and the new measure. 22 sets of CT scans were retrieved from the QUT/Mater Paediatric Spinal Research Database. The Image J software (NIH) was used to manipulate formatted CT scans into 3-dimensional anterior chest wall reconstructions. A ‘chest wall angle’ was then measured in relation to the first sacral vertebral body. The chest wall angle was found to be a reliable tool in the analysis of chest wall deformity. No correlation was found between the new measure and rib hump angle. Since rib hump has been shown to correlate with vertebral rotation on CT, this suggests that there maybe no correlation between anterior and posterior deformity measures. While most surgical procedures will adequately address the coronal imbalance & posterior rib hump elements of scoliosis, they do not reliably alter the anterior chest wall shape. This implies that anterior chest wall deformity is to a large degree an intrinsic deformity, not directly related to vertebral rotation.

α-Synuclein pathology in very elderly Finns : A population-based clinico-neuropathologic and molecular genetic study of Dementia with Lewy bodies

Populations in developed countries are ageing fast. The elderly have the greatest incidence of de-mentia, and thus the increase in the number of demented individuals, increases the immediate costs for the governments concerning healthcare and hospital treatment. Attention is being paid to disorders behind cognitive impairment with behavioural and psychological symptoms, which are enormous contributors to the hospital care required for the elderly. The highest dreams are in prevention; however, before discovering the tools for preventing dementia, the pathogenesis behind dementia disorders needs to be understood. Dementia with Lewy bodies (DLB), a relatively recently discovered dementia disorder compared to Alzheimer’s disease (AD), is estimated to account for up to one third of primary degenerative dementia, thus being the second most common cause of dementia in the elderly. Nevertheless, the impact of neuropathological and genetic findings on the clinical syndrome of DLB is not fully established. In this present series of studies, the frequency of neuropathological findings of DLB and its relation to the clinical findings was evaluated in a cohort of subjects with primary degenerative dementia and in a population-based prospective cohort study of individuals aged 85 years or older. α-synuclein (αS) immunoreactive pathology classifiable according to the DLB consensus criteria was found in one fourth of the primary degenerative dementia subjects. In the population-based study, the corresponding figure was one third of the population, 38% of the demented and one fifth of the non-demented very elderly Finns. However, in spite of the frequent discovery of αS pathology, its association with the clinical symptoms was quite poor. Indeed, the common clinical features of DLB, hypokinesia and visual hallucinations, associated better with the severe neurofibrillary AD-type pathology than with the extensive (diffuse neocortical) αS pathology when both types of pathology were taken into account. The severity of the neurofibrillary AD-type pathology (Braak stage) associated with the extent of αS pathology in the brain. In addition, the genetic study showed an interaction between tau and αS; common variation in the αS gene (SNCA) associated significantly with the severity of the neurofibrillary AD-type pathology and nominally significantly with the extensive αS pathology. Further, the relevance and temporal course of the substantia nigra (SN) degeneration and of the spinal cord αS pathology were studied in relation to αS pathology in the brain. The linear association between the extent of αS pathology in the brain and the neuron loss in SN suggests that in DLB the degeneration of SN proceeds as the αS pathology extends from SN to the neocortex instead of early destruction of SN seen in Parkinson’s disease (PD). Furthermore, the extent of αS pathology in the brain associated with the severity of αS pathology in the thoracic and sacral autonomic nuclei of the spinal cord. The thoracic αS pathology was more common and more severe compared to sacral cord, suggesting that the progress of αS pathology proceeds downwards from the brainstem towards the sacral spinal cord.

Hautamuistomerkki elämän ja kuoleman tulkitsijana : Heikki Häiväojan, Kain Tapperin ja Matti Peltokankaan tekemät hautamuistomerkit 1952-2002

Grave sculpture as interpreter of life and death. Grave sculptures done by Heikki Häiväoja, Kain Tapper and Matti Peltokangas 1952-2002. The thoughts of Philippe Ariès and Erwin Panofsky on western funeral art constitute the starting point of this study. These scholars speak about the 20th century as a period of decline regarding western funeral art. The reason for this situation lies, according to them, in the fact that death has been rejected and become a private affair in modern society. Especially Panofsky sees an important reason for the decay of funeral art also in the separation of death from religion. In this study, I approach the view of Ariès and Panofsky from the angle of Finnish funeral art. The subject of the study is grave sculptures of three Finnish sculptors: Heikki Häiväoja, Kain Tapper and Matti Peltokangas, from 1952 to 2002. (The analysis of the grave sculptures has been performed with the Iconology of Erwin Panofsky. The analysis has been deepened by the ideas of a graveyard as a semiotic text according to Werner Enninger and Christa Schwens. In order to confirm their argumentation, they analyse the graveyard text with the model of communicative functions of Roman Jakobson and verify that the graveyard is a cultural text according to Juri Lotman.) Results of the study In the grave sculptures of the sculptors, different worldviews appear alongside Christian thoughts indicating a new stage in the tradition of funeral art. In the grave sculptures characterised as Christian, the view of life after death is included. In these memorials the direction of life is prospective, pointing to the life beyond. Death is a border, beyond which one is unable to see. Nevertheless the border is open or marked by the cross. On this open border, death is absence of pain, glory and new unity. In memorials with different worldviews, the life beyond is a possibility which is not excluded. Memorials interpret life retrospectively; life is a precious memory which wakens grief and longing. Many memorials have metaphysical and mystic features. In spite of democratization the order and valuation of social classes appear in some memorials. The old order also materializes in the war memorials relating the same destiny of the deceased. Different burial places, nevertheless, do not indicate social inequality but are rather signs of diversity. The sculptors' abstract means of modern funeral art deepen the handling of the subject matter of death and reveal the mystery of it. Grave sculptures are a part of Finnish and sacral modern art, and there is an interaction between funeral art and modern art. Modern art acquires a new dimension, when grave sculptures become a part of its field. Grave sculptures offer an alternative to anonymous burying. The memorial is a sign of the end of life; it gives death significance and publicity and creates a relation to the past of the society. In this way, grave sculptures are a part of the chain of memory of the western funeral art, which extends throughout Antiquity until ancient Egypt. (In this study I have spoken of funeral art as a chain of memory using the thoughts of Danièle Hervieu-Léger.) There are no signs of decay in the grave sculptures, on the contrary the tradition of funeral art continues in them as a search for the meaning of life and death and as an intuitive interpretation of death. As such, grave sculptures are part of the Finnish discussion of death.

El imaginario de la luz en la mística cortés de Matilde de Magdeburgo : continuidad y transformación de la herencia hildegardiana en el siglo XIII

El artículo se propone desarrollar la continuidad y proyección de la estética de Hildegarda de Bingen en el siglo XIII a través del estudio del imaginario de la luz en la obra La luz fluyente de la divinidad de Matilde de Magdeburgo. El paso de una estética espacial de lo ígneo hacia una estética temporal de lo líquido se corresponde con la transformación del paradigma sacral feudal en el de la mística cortés, a cuyos tópicos responde la obra de esta última. La figura de Matilde, que se vuelve una con su obra, describe una curva que va desde la cosmología simbólica, por la mística cortés del Amor, hacia la mística del abismo y del desierto que brota del grito inarticulado de la cruz y que proyecta su influencia hacia el siglo XIV. En el dinamismo de la simbólica del agua y de las imágenes nupciales que acompañan a esta luz fluyente del amor, Matilde ha dejado trazadas sendas para pensar, en lenguaje estético, la experiencia de Dios en nuestro siglo XXI.

Estudo do tempo de trânsito colônico em crianças e adolescentes com constipação intestinal crônica e disfunção do trato urinário inferior

A constipação intestinal e a disfunção do trato urinário inferior são condições associadas e bastante prevalentes na infância e adolescência. Existem múltiplas teorias para explicar essa associação, como: o efeito mecânico do reto cheio sobre a parede e o colo vesical; estimulo de reflexos sacrais a partir do reto distendido, e mais recentemente, a associação entre a bexiga e o reto no sistema nervoso central. Muitas destas crianças e adolescentes apresentam constipação refratária. Esse fato chama a atenção para a possibilidade de existência de uma desordem neuromuscular comum envolvendo o cólon e o trato urinário inferior. O objetivo desse estudo foi avaliar o trânsito colônico de crianças e adolescentes com constipação crônica refratária e sintomas do trato urinário inferior. Foi realizado um estudo observacional com análise transversal, no qual foram incluídos 16 indivíduos com constipação refratária e sintomas do trato urinário inferior, com idades entre sete e 14 anos (média de idade de 9,67 anos). Os participantes foram avaliados utilizando anamnese padrão; exame físico; diário miccional e das evacuações; escala de Bristol; Disfunctional Voiding Scoring System com versão validada para o português; ultrassonografia renal, de vias urinárias e medida de diâmetro retal; urodinâmica, estudo de trânsito colônico com marcadores radiopacos e manometria anorretal. O estudo de trânsito foi normal em três (18,75%) crianças, dez (62,5%) apresentaram constipação de trânsito lento e três (18,75%) obstrução de via de saída. A avaliação urodinâmica estava alterada em 14 das 16 crianças estudadas: dez (76,9%) apresentaram hiperatividade detrusora associada à disfunção miccional, três (23,1%) hiperatividade vesical isolada e um (6,25%) disfunção miccional sem hiperatividade vesical. Ao compararmos constipação de trânsito lento e disfunção do trato urinário inferior, dez (100%) sujeitos com constipação de trânsito lento e três (50%) sem constipação de trânsito lento apresentavam hiperatividade vesical (p=0,036). Sete (70%) sujeitos com constipação de trânsito lento e quatro (66,7%) sem constipação de trânsito lento apresentavam disfunção miccional (p=0,65). Ao compararmos constipação de trânsito lento e a presença de incontinência urinária, esta estava presente em nove (90%) participantes com constipação de trânsito lento e em um (16,7%) sem constipação de trânsito lento (p = 0,008). Quanto à urgência urinária, estava presente em 10 (100%) e três (50%) respectivamente (p = 0,036). O escore do Disfunctional Voiding Scoring System variou de 6 a 21. O subgrupo com constipação de trânsito lento mostrou um escore de Disfunctional Voiding Scoring System significativamente maior que o subgrupo sem constipação de trânsito lento. O presente estudo demonstrou alta prevalência de constipação de trânsito lento em crianças e adolescentes com constipação refratária e sintomas do trato urinário inferior. Este estudo foi pioneiro em demonstrar a associação entre hiperatividade vesical e constipação de trânsito lento e coloca em voga a possibilidade de uma desordem neuromuscular comum, responsável pela dismotilidade vesical e colônica. Futuros estudos envolvendo a motilidade intestinal e vesical são necessários para melhor compreensão do tema e desenvolvimento de novas modalidades terapêuticas.
