Application of current sarcopenia definitions in spinal cord injury.

OBJECTIVE: Little is known about how appropriate the working definitions of sarcopenia are in subjects with spinal cord injury (SCI). This study aimed to evaluate the application of current sarcopenia definitions in SCI. METHODS: We compared 31 complete SCI men with 33 able-bodied age matched subjects. All were examined by whole body DXA (Norland XR 36, USA) regarding muscle and fat mass and by peripheral quantitative computed tomography (pQCT XCT-3000, Germany) in 66% of tibia's length (muscle cross sectional area, (CSA) in mm2). Low muscle mass was defined by skeletal muscle index, (SMI= appendicular lean mass (aLM)/height2 in Kg/m2) and by the residual method: relative aLM, 20th percentile of the distribution of residuals as the cutoff point, (RASM), respectively. CSA is a surrogate for force. RESULTS: We found lower values on RASM (p<0.001), and SMI (p<0.001) compared to controls in SCI and difference in the rate of sarcopenia according to sarcopenia definitions. CSA was significantly decreased in SCI (p<0.001) and correlation with duration of paralysis was weak. CONCLUSION: Current functional definitions of sarcopenia classify different individuals as sarcopenic. Sarcopenia was more prevalent in SCI. The sensitivity and specificity of using these measurements in SCI remain unclear.

Gap in stroke patients' and carers' education.

Stroke is a multidimensional illness as it affects various aspects in a person's quality of life. The rehabilitation team focuses mainly on complications but there seems to be a gap in the education of the patients and their carers in skills relevant to the competencies required for community, aged care, health, housing and disability support services. Stroke patients' and carers' education-training, as well as their satisfaction has not been studied adequately. The current article presents important studies in the field about the association of patients' and carers' satisfaction and based on authors' opinion suggests appropriate interventions in order to improve the health of the patients.

Nutritional Alterations Associated with Neurological and Neurosurgical Diseases.

Neurological and neurosurgical diseases lead to complications producing malnutrition increasing pathology and mortality. In order to avoid complications because of malnutrition or overcome deficiencies in nutrients supplements are often used for these subjects. The physiopathological mechanisms of malnutrition, methods of nutritional assessment and the supplemental support are reviewed in this paper based on the assumption that patients need to receive adequate nutrition to promote optimal recovery, placing nutrition as a first line treatment and not an afterthought in the rehabilitation.

Patients with pelvic fractures due to falls: A paradigm that contributed to autopsy-based audit of trauma in Greece.

BACKGROUND: Evaluation of the pelvic fractures (PFx) population in auditing effective components of trauma care is the subject of this study. METHODS: A retrospective, case-control, autopsy-based study compared a population with PFx to a control-group using a template with trauma outcome variables, which included demographics, ICD-9, intention, mechanisms, toxicology, Abbreviated Injury Scale (AIS-90), Injury Severity Score (ISS), causes of haemorrhage, comorbidity, survival time, pre-hospital response, in hospital data, location of death, and preventable deaths. RESULTS: Of 970 consecutive patients with fatal falls, 209 (21.5%) had PFx and constituted the PFx-group while 761 (78.5%) formed the control-group.Multivariate analysis showed that gender, age, intention, and height of fall were risk factors for PFx. A 300% higher odds of a psychiatric history was found in the PFx-group compared to the control-group (p < 0.001).The median ISS was 50 (17-75) for the PFx-group and 26 (1-75) for the control-group (p < 0.0001). There were no patients with an ISS less than 16 in the PFx group.Associated injuries were significantly more common in the PFx-group than in the control-group. Potentially preventable deaths (ISS < 75) constituted 78% (n = 163) of the PFx-group. The most common AIS3-5 injuries in the potentially preventable subset of patients were the lower extremities in 133 (81.6%), thorax in 130 (79.7%), abdomen/pelvic contents in 99 (60.7%), head in 95 (58.3%) and the spine in 26 (15.9%) patients.A subset of 126 (60.3%) potentially preventable deaths in the PFx-group had at least one AIS-90 code other than the PFx, denoting major haemorrhage. Deaths directly attributed to PFx were limited to 6 (2.9%).The median survival time was 30 minutes for the PFx-group and 20 hours for the control-group (p < 0.001). For a one-group increment in the ISS-groups, the survival rates over the post-traumatic time intervals were reduced by 57% (p < 0.0001).Pre-hospital mortality was significantly higher in the PFx-group i.e. 70.3% of the PFx-group versus 42.7% of the control-group (p < 0.001). CONCLUSIONS: The PFx-group shared common causative risk factors, high severity and multiplicity of injuries that define the PFx-group as a paradigm of injury for audit. This reduced sample of autopsies substantially contributed to the audit of functional, infrastructural, management and prevention issues requiring transformation to reduce mortality.

Good results after major pancreatic resections in a middle-volume center.

OBJECTIVES: Recently, hospital and surgeon volume is widely discussed as a prognostic factor after major pancreatic surgery. We present our experience regarding major pancreatectomy in a middle-volume center. METHODS: During the last 11 years, 66 patients underwent major pancreatectomy (pancreaticoduodenectomy [n = 52], distal pancreatectomy with splenectomy [n = 13], and central pancreatectomy [n = 1]). Postoperative course and long-term outcome were recorded and analyzed. RESULTS: One patient died after pancreaticoduodenectomy for ampullary cancer (total mortality of approximately 1.5% for the whole group of patients or 1.9% for the group of patients who underwent pancreatoduodenectomy). None of our patients was reoperated on. Transient pancreatic fistula was observed in 46 patients (36 patients after pancreatoduodenectomy [69%] and 10 patients after distal pancreatectomy [77%]). Two patients required percutaneous computed tomography-guided drainage of fluid collections, whereas in another one, a tube thoracostomy was performed to drain a pleuritic fluid collection. Delayed gastric emptying was observed in 6 patients after pancreatoduodenectomy. Median survival for the whole group of patients was 17 months. CONCLUSIONS: Major pancreatic resections can be performed safely, with acceptable morbidity and mortality and good long-term results, even in middle-volume centers. However, experience is required from the part of the operating surgeon. ABBREVIATIONS: PD - pancreatoduodenectomy, DP - distal pancreatectomy, PPPD - pylorus-preserving pancreatoduodenectomy.

Ultrasound-guided catheterization of the internal jugular vein in oncologic patients; comparison with the classical anatomic landmark technique: a prospective study.

AIM: To compare the traditional anatomic landmark technique with the ultrasound-guided method for central venous catheterization. MATERIAL AND METHODS: During three years, 551 patients underwent internal jugular vein catheterization; in 347 patients, the ultrasound-guided technique was used, while in the other 204 patients the catheter was introduced by using the classical anatomic landmark method. Operating time, complications (pneumothorax, puncture of carotid artery with or without hematoma formation), and number of attempts to achieve central venous catheterization were recorded. RESULTS: The ultrasound-guided technique was associated with significantly shorter operating time (9.83+/-3.1 vs. 20+/-4.4 min, p<0.001) and less morbidity (pneumothorax, 0 vs. 2 patients [p<0.05], carotid artery puncture with or without hematoma formation, 1 vs. 16 patients [p<0.05]). Moreover, the ultrasound-guided technique was highly successful in achieving central venous catheterization (failure, 0 vs. 18 patients [p<0.05]), with significantly fewer attempts (1-3 attempts in 204 vs. 283 [p<0.01]), compared to the classical anatomic landmark technique. CONCLUSION: The ultrasound-guided method is faster, more efficient, and less morbid procedure compared with the classical anatomic landmark technique. Therefore, it should be preferred over the classical landmark method, especially in high-risk patients for the development of complications.

European consensus table on the use of botulinum toxin type A in adult spasticity.

A group of clinicians from across Europe experienced in the use of botulinum toxin type A for the treatment of spasticity following acquired brain injury gathered to develop a consensus statement on best practice in managing adults with spasticity. This consensus table summarizes the current published data, which was collated following extensive literature searches, their assessment for level of evidence and discussion among the whole group. Published information is supplemented by expert opinion based on clinical experience from 16 European countries, involving 28 clinicians, who treat an average of approximately 200 patients annually, representing many thousand spasticity treatments with botulinum toxin per year.

Body composition in paraplegic men.

To investigate alterations in the body composition of paraplegic men, 31 complete paraplegic men thoracic (T)4-T 12 neurological level of injury, 16 with paraplegia above (high), and 15 below (low) thoracic 7, were compared with 33 able-bodied men. Whole body dual X-ray absorptiometry was used to estimate regional (arms, legs) and total body bone mineral density (g/cm(2)), lean, and fat mass (g).The influence of the neurological level of injury and the duration of paralysis in relation with the above parameters were also investigated. Body mass index, bone mineral density, and lean mass were significantly decreased (p < 0.0005) and fat mass was increased (p < 0.05) in the legs and total body composition in paraplegics. Bone mineral density was significantly lower in high paraplegics' arms compared with low paraplegics (p = 0.028). The correlation of body mass index with fat mass was statistically significant in all paraplegics and controls (r = 0.57, p = 0.001 and r = 0.73, p = 0.0001, respectively) and in low paraplegics (r = 0.72, p = 0.004). Legs' bone mineral density and arms' fat mass were correlated with the duration of paralysis in all paraplegics (r = -0.46, p = 0.009 and r = 0.43, p = 0.020, respectively) and in high paraplegics (r = 0.73, p = 0.001 and r = 0.55, p = 0.042, respectively). Total fat mass was correlated with the duration of paralysis in high paraplegics (r = 0.5, p = 0.05). These results suggest body composition changes in paraplegics.

Urinary frequency in a case of Neuro-Behcet disease involving the brainstem - clinical, electrophysiological and urodynamic features.

Micturitional disturbances are reported in 5-20% of patients with Behcet disease (BD) affecting the central nervous system. However, corresponding data regarding urodynamic and electrophysiological findings are limited. A patient with known BD presented with dysarthria, diplopia and urinary frequency (36 times/day). MRI revealed an extensive lesion involving the lateral and tegmental pons, reaching the pontomedullary junction. Auditory evoked potentials indicated a left-side lesion between superior olivary nucleus and superior colliculus. Blink reflex examination indicated a location caudal to the left trigeminal root. Pudendal nerve somatosensory evoked potentials and transcranial magnetic stimulation of the perineal muscles were slightly affected. Bulbocavernosus reflex latencies were normal. EMG of the bulbocavernosus muscles showed a normal maximal voluntary contraction activity. Urodynamic studies revealed normal urine volume, maximum flow rate and residual volume. After intravenous administration of methylprednisolone diplopia and dysarthria resolved within 3 weeks. Urinary frequency remained almost unchanged for the first 8 weeks, but clearly improved during the following months. We assume that the present case of urinary frequency is the result of vasculitic lesion affecting the pontine micturition inhibitory area on the ground of Neuro-Behcet disease.

Endovascular treatment of a bleeding secondary aorto-enteric fistula. A case report with 1-year follow-up.

We report a patient with life-threatening gastrointestinal bleeding caused by a secondary aorto-enteric fistula. Because the patient had several comorbid conditions, we succesfully stopped the bleeding by endovascular placement of a bifurcated aortic stent-graft. The patient developed periaortic infection 4 months later, but he was managed with antibiotics. The patient is well 1 year after the procedure.

A combined urodynamic and electrophysiological study of diabetic cystopathy.

AIMS: The aim of this study is to compare urodynamics and electrophysiological studies in the diagnosis of diabetic cystopathy. MATERIALS AND METHODS: In this prospective study are included twenty six patients with diabetes mellitus diagnosed at least since 5 years; 17 patients with diabetes type II and 9 with type I. They were divided in two groups in respect to lower urinary tract symptoms (LUTS) and signs suggestive of lower urinary tract dysfunction (LUTD) according to the ICS standardization. Patients with LUTS/LUTD were included in Group A and patients without LUTS/LUTD in Group B. Patients underwent different studies: urodynamic, somatosensory evoked potentials (SSEP) of tibial and pudendal nerves, bulbocavernosus reflex (BCR), bulbocavernosus muscles' electromyography and motor evoked potentials after transcranial magnetic stimulation to indirectly investigate bladder's innervation. RESULTS: Abnormal urodynamics were found in 13 patients of group A (92.9%) and in 5 of group B (47.1%). This difference was statistically significant (P=0.009). Abnormally prolonged latency of P40 of tibial SSEP was found in 11 patients of group A (78.6%) and in 4 of group B (33.3%) and this difference was also statistically significant (P=0.04). Differences between the two groups concerning: i) peripheral polyneuropathy; ii) pudendal SSEP, iii) dysfunction of central nervous system and iv) abnormal BCR were not statistically significant. CONCLUSION: The study of tibial SSEP is an easily performed test and it is well correlated to abnormal urodynamics in diabetic patients with and without LUTD/LUTS.
