    Sacral pressure ulcers (PUs) are a serious complication in frail elderly patients. Thin tissue in the sacral area, low body mass index, and anatomical location contribute to the development of sacral PUs. A comparative, descriptive study was conducted to identify patient systemic factors associated with sacral PUs and to compare survival time in patients with and without PU. All consecutive patients with PUs (n = 77) and without sacral PUs (n = 53) admitted to the skilled nursing department of a geriatric hospital in Jerusalem, Israel between July 1, 2008 and December 31, 2011 were eligible to participate. Charts of previously admitted patients were abstracted and patients were prospectively followed until discharge, death, or the end of the study. Patient demographics, comorbidities, nutritional status, physical and cognitive function (measured using the Reisberg's Functional Assessment Staging Tool [FAST], Stages of Dementia of Alzheimer Scale, and the Glasgow Coma Scale), PU status, number of courses of antibiotic treatment during admission, length of hospitalization, and mortality were compared between patients admitted with and without a sacral PU using descriptive and univariate statistics. Logistic regression models were used to estimate the odds ratio (OR) and 95% confidence intervals (CI) for sacral PU versus without PU by study covariate. The association between sacral PU and survival time was assessed using Kaplan-Meier models. Patients with a sacral PU were significantly older (average age 81.60 ±10.78 versus 77.06±11.19 years old, P = 0.02) and had a higher prevalence of dementia (70% versus 30%, P = 0.007), Parkinson's disease (92.3% versus 7.7%, P = 0.03), and anemia (67.7% versus 32.3%, P = 0.06) than patients admitted without a PU. Patients with a sacral PU also had a lower body mass index (23.1 versus 25.4, P = 0.04), and lower hemoglobin (10.54 versus 11.11, P = 0.03), albumin (26.2 versus 29.7, P = 0.002), and total protein levels (61.3 versus

    Objective:To investigate the effect of injecting a compound of Bupivacaine and Fentanyl into sacral spinal space to treat chronic pelvic pain syndrome (CPPS). Methods: A total of 36 men with recalcitrant CPPS refractory to multiple prior therapies were treated with the injection of a compound of Bupivacaine and Fentanyl (10 ml of 0. 125% upivacaine, .05 mg Fentanyl, 5 mg Dexamethasone, 100 mg Vitamin B1 and 1 mg Vitamin B12) into sacral space once a week for 4 weeks. The National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI), maximum and average flow rate were performed at the start and the end of 4 weeks' therapy. Results :Mean NIH-CPSI total score was decreased from 26.5±.6 to 13.4±2.0 (P<0. 001). Significant improvement was seen in each subscore domain. A total of 32 patients (89%) had at least 25% improvement on NIH-CPSI and 22 (61%) had at least 50% improvement. Maximal and average flow rate were increased from 19. 5±3.8 to 23. 6±4. 2 and 10. 9±2.6 to 14.3± 2.4 respectively. Conclusion: Injection of this compound of Bupivacaine, Fentanyl and Dexamethasone into sacral spinal space is an effective and safe approach for recalcitrant CPPS. Further study of the mechanisms and prospective placebo controlled trials are warranted.

    Despite advances in reconstruction techniques, sacral pressure ulcers continue to present a challenge to the plastic surgeon. The flap from the gluteal crease derives blood supply from the inferior gluteal artery perforator (IGAP) and reliably preserves the entire contralateral side as a donor site. To incorporate the IGAP in the reconstruction of sacral pressure ulcers, a skin paddle over the gluteal crease was created and implemented by the authors. Data from 11 patients (8 men, 3 women; mean age 67 [range 44-85] years old) whose sacral ulcers were closed with an IGAP flap between June 2006 and May 2012 were retrieved and reviewed. All patients were bedridden; 1 patient in a vegetative state with a diagnosis of carbon monoxide intoxication was referred from a local clinic, 2 patients had Parkinson's disease, and 8 patients had a history of stroke. The average defect size was 120 cm(2) (range 88-144 cm(2)). The average flap size was 85.8 cm(2) (range 56-121 cm(2)). Only 1 flap failure occurred during surgery and was converted into V-Y advancement flap; 10 of the 11 flaps survived. After surgery, the patients' position was changed every 2 hours; patients remained prone or on their side for approximately 2 weeks until the flap was healed. After healing was confirmed, patients were discharged. Complications were relatively minor and included 1 donor site wound dehiscence that required wound reapproximation. No surgery-related mortality was noted; the longest follow-up period was 24 months. In this case series, flaps from the gluteal crease were successfully used for surgical closure of sacral pressure ulcers. This flap design should be used with caution in patients with hip contractures. Studies with larger sample sizes are needed to ascertain which type of flap is best suited to surgically manage extensive pressure ulcers in a variety of patient populations. PMID:26779702

    Objective. To delineate the clinical spectrum and treatment choice of sacral fractures.Methods. In this series, 39 sacral fractures were retrospectively reviewed and classified utilizing Denis′ classification. There were 21 Zone Ⅰ fractures, 6 Zone Ⅱ fractures and 12 Zone Ⅲ fractures. Neurological deficits were present in seven patients. Thirty seven patients were treated conservatively and two underwent surgical management.Results.Thirty eight patients were followed up for three months to 19 years. Thirty three have recovered, four improved, and one remained disabled.Conclusion.The treatment of sacral fractures requires assessment of pelvic stability and existing nerve injury. The patients with pelvic ring instability and neurological deficits should be treated with fracture reduction and stability reconstruction. When the patients with pelvic fracture are complicated with neurological deficits, sacral fracture should be first suspected. Once the diagnosis of sacral fracture is made, fracture reduction should be indicated. Conservative treatment usually permits satisfactory results.

Eighty five male (56) and female (29) subjects comprising 45 youths (18-28 years old) and 42 elders (65-75 years old), including LBP (40) and pain-free individuals participated in the study. Subjects with LBP received VOP on each vertebra from the first lumbar to the sacrum, 10 oscillations in one minute repeated at each vertebra. Pain intensity (measured using Borg's 10 point scale) and mobility were measured at the start, after VOP and five minutes after cryotherapy. Control subjects did not receive VOP and cryotherapy but had their sensory perception and spinal mobility measured at the start, after 15 and 26 minutes respectively. Pain intensity decreased significantly [elders, pCryotherapy after VOP therapy did not add any significant effect on pain intensity and trunk mobility. Mobility and perceptual levels of the control subjects did not alter significantly. Pain intensity and flexion (forward and side flexions in elders only) are improved by VOP and should be preferred spinal mobilization therapy outcome measures in youths and elders with LBP respectively.

    Although most of sacral perineural cysts are asymptomatic, some may produce symptoms. Specific radicular pain may be due to distortion, compression, or stretching of nerve root by a space occupying cyst. We report a rare case of S1 radiculopathy caused by sacral perineural cyst accompanying disc herniation. The patient underwent a microscopic discectomy at L5-S1 level. However, the patient's symptoms did not improved. The hypesthesia persisted, as did the right leg pain. Cyst-subarachnoid shunt was set to decompress nerve root and to equalize the cerebrospinal fluid pressure between the cephalad thecal sac and cyst. Immediately after surgery, the patient had no leg pain. After 6 months, the patient still remained free of leg pain. PMID:19352483

    2006-01-01

    Objective: To observe the morphological characteristics of sacral fracture under different impact loads.Method: Ten fresh pelvic specimens were loaded in dynamic or static state. A series of mechanical parameters including the pressure strain and velocity were recorded.Morphological characteristics were observed under scanning electron microscope.Results: The form of sacral fracture was related to the impact energy. Under low-energy impact loads, ilium fracture, acetabulum fracture and crista iliaca fracture were found. Under high-energy impact loads, three types of sacral fracture occurred according to the classification of Denis: sacral ala fracture, Type Ⅰ fracture; sacral foramen cataclasm fracture, Type Ⅱ fracture; central vertebral canal fracture, Type Ⅲ fracture. Nerve injury of one or two sides was involved in all three types of sacral fracture.The fracture mechanism of sacrum between the dynamic impact and static compression was significantly different.When the impact energy was above 25 J, sacral foramen cataclasm fracture occurred, involving nerve root injury.When it was below 20 J, ilium and sacral fracture was most likely to occur. When it was 20 ~ 25 J, Type Ⅰ fracture would occur. While in the static test, most of the fracture belonged to ilium or acetabulum fracture. The cross section of sacrum was crackly and the bone board of Haversian system was brittle, which could lead to separation of bone boards and malposition of a few of cross bone boards.Conclusions: In dynamic state, sacrum fracture mostly belongs to Type Ⅰ and Type Ⅱ, and usually involves the nerve roots. Sacrum fracture is relevant to the microstructures, the distribution of the bone trabecula, the osseous lacuna and the Haversian system of sacrum. The fracture of ilium and acetabulum more frequently appears in static state, with slight wound of peripheral tissues.

    An elderly woman with a chronic decubitus sacral ulcer presented to the emergency department with sepsis. A computed tomography of her abdomen showed diffuse gas extending throughout the thoracolumbar spinal canal. Pneumorrhachis is a rare radiographic finding defined as gas within the spinal canal. There are many causes of pneumorrhachis ranging from trauma to infection. In this case the pneumorrhachis was caused by direct spread of gas-forming organisms from vertebral osteomyelitis. Emergency physicians should know about the implication of gas in the spinal canal in the setting of sepsis. PMID:27429699

    Three cases of sacral perineural cysts associated with chronic low-back pain are described with their myelography, computed tomography, and plain film findings. Significant findings include multiple cystic dilatations of lumbosacral nerve root sheaths, enlargement of the sacral foramina by masses isodense with cerebrospinal fluid, and asymmetric epidural fat distribution. Recognition of these findings on unenhanced computed tomography scans should preclude further evaluation by myelography and intrathecal metrizamide (Amipaque) computed tomography. These cysts are usually not the primary cause of back and leg pain. PMID:2942338

  3. The application of sacral block anesthesia in pediatric interventional therapy

    International Nuclear Information System (INIS)

    Objective: To discuss the management and feasibility of sacral block anesthesia in pediatric interventional therapy. Methods: A total of 80 pediatric patients were randomly and equally divided into two groups. Patients in group A received sacral block anesthesia together with basic anesthesia with propofol, while patients in group B received intravenous anesthesia with propofol. Small amount of ketamine as maintaining dose was used in both groups when needed. Results: The interventional management was successfully completed in all patients. A marked decrease in blood pressure occurred in three patients of group A receiving sacral block anesthesia. In group B receiving intravenous anesthesia, a decrease of SpO2 to below 90 percent was seen in 8 cases, and obvious bradycardia developed in 12 cases. All these patients were treated with intravenous medication or by reducing the dose of propofol. Additional small dose of ketamine was needed in 4 patients during the procedure. Conclusion: Sacral block anesthesia combined with intravenous anesthesia is one of the effective anesthesia management schemes for pediatric interventional therapy. (authors)

    Sacral perineural cyst is a relatively rare condition. To our knowledge, reports of MR findings associated with sacral perineural cyst have been limited to only six cases. We present for the first time high field MR findings in a case of sacral perineural cyst. The cyst appeared as a cystic lesion in the sacral spinal canal and had intermediate signal intensity on T1W images and high signal intensity on T2*W images compared with CSF. Slight erosion remodeling of the sacrum was also seen anteriorly. Our case was symptomatic and present with radiculopathy (sciatic pain). Surgical treatment was done to result in dramatic improvement of the sciatic pain. PMID:1337620

Symptomatic sacral perineural cysts are uncommon but sometimes require surgical treatment. A 69-year-old male presented with pain in the buttock. He was diagnosed as having a sacral cyst with magnetic resonance imaging. For the nonoperative diagnosis and treatment, caudal peridurography and block were performed. After the treatment, the patient's symptom was relieved. We suggest a caudal peridural block is effective in relieving pain from a sacral cyst. PMID:22787551

    Full Text Available The perforator-based flaps in the sacral and ischial region is designed according to the localization of perforators that penetrate the gluteus maximus muscle, reach the intra-fascial and supra-fascial planes with the overlying skin forming a rich vascular plexus. The perforator-based flaps described in this article are highly vascularized, have minimal donor site morbidity, and do not require the sacrifice of the gluteus maximus muscle. In a period between April 2008 and March 2009, six patients with sacral pressure sore were reconstructed with propeller flap method based on superior gluteal and parasacral artery perforators. One flap loss was noted. Three cases of ischial pressure sore were reconstructed with longitudinal propeller flap cover, based on inferior gluteal artery perforator. One flap suffered wound infection and dehiscence. Two cases of pilonidal sinus were reconstructed with propeller flap based on parasacral perforators. Both the flaps survived without any complications. Donor sites were closed primarily. In the light of this, they can be considered among the first surgical choices to re-surface soft tissue defects of the sacral and ischial regions. In the series of 11 patients, two patients (18% suffered complications.

    International Nuclear Information System (INIS)

    The posterior rings of the lower lumbo-sacral vertebrae are subject to stress fractures at any part - pedicle, pars, or lamina. The site of fracture is apparently determined by the axis of weight bearing. The three illustrative clinical examples cited include a jogger with a laminar fracture, a ballet dancer with pedicle fractures, and a nine-year-old boy with fractures of pars and lamina. Chronic low back pain is the typical complaint with stress fractures of the lower lumbo-sacral spine. Special imaging techniques are usually needed to demonstrate these lesions, including vertebral arch views, multi-directional tomography, and computed tomography (CT). (orig.)

In the case under report, the fat attached to the neural placode was blending with the gluteal fat externally. The cord was tethered at this level. Multiple bony anomalies and diastematomyelia were associated findings. A case of lateral sacral lipomyelomeningocele with excellent imaging detail provided by the multiplanar magnetic resonance (MR scan is reported.

  13. Central Blood Pressure and Chronic Kidney Disease Progression

    Full Text Available Hypertension, diabetes, and proteinuria are well-recognized risk factors for progressive kidney function loss. However, despite excellent antihypertensive and antidiabetic drug therapies, which also often lower urinary protein excretion, there remains a significant reservoir of patients with chronic kidney disease who are at high risk for progression to end-stage kidney disease. This has led to the search for less traditional cardiovascular risk factors that will help stratify patients at risk for more rapid kidney disease progression. Among these are noninvasive estimates of vascular structure and function. Arterial stiffness, manifested by the pulse wave velocity in the aorta, has been established in a number of studies as a significant risk factor for kidney disease progression and cardiovascular endpoints. Much less well studied in chronic kidney disease are measures of central arterial pressures. In this paper we cover the physiology behind the generation of the central pulse wave contour and the studies available using these approaches and conclude with some speculations on the rationale for why measurements of central pressure may be informative for the study of chronic kidney disease progression.

    Objective. To review imaging studies of isolated involvement of the sacrum due to tuberculosis and determine the role of imaging in the diagnosis and management of these patients.Design and patients. A retrospective analysis of 15 cases of isolated sacral tuberculosis imaged with MR imaging was performed. The CT images were also reviewed where available, and the various lesion characteristics were identified. We also reviewed the medical records in an attempt to determine the impact of the imaging studies on the management of these patients.Results. Fifteen patients (5 male, 10 female) presented with symptoms of 3-15 months' duration. Chronic localized backache with muscle spasm was the commonest presenting symptom; discharging sinuses with abscess formation was found in six patients, five of whom were children. MR imaging of the sacrum revealed a hypointense marrow signal on T1-weighted images and hyperintense signal on T2-weighted images in 14 of 15 patients, the S2 vertebra being always involved. CT revealed osteolytic changes in the sacrum in all the five patients in whom CT was performed. All patients showed marked clinical improvement within 1 year of anti-tuberculous chemotherapy.Conclusion. Isolated tuberculosis of the sacrum is uncommon but should be suspected in patients presenting with chronic low backache or children with discharging sinuses/abscesses and showing sacral destruction on CT or MR imaging. MR imaging can identify cases and enables early institution of anti- tuberculous chemotherapy. (orig.)

    The purpose of this study was to investigate the surgical outcomes and to determine indicators of the necessity of surgical intervention. Twelve consecutive patients harboring symptomatic sacral perineural cysts were treated between 1995 and 2003. All patients were assessed for neurological deficits and pain by neurological examination. Magnetic resonance of imaging, computerized tomography, and myelography were performed to detect signs of delayed filling of the cysts. We performed a release of the valve and imbrication of the sacral cysts with laminectomies in 8 cases or recapping laminectomies in 4 cases. After surgery, symptoms improved in 10 (83% of 12 patients, with an average follow-up of 27 months. Ten patients had sacral perineural cysts with signs of positive filling defect. Two (17% of 12 patients experienced no significant improvement. In one of these patients, the filling defect was negative. In conclusion, a positive filling defect may become an indicator of good treatment outcomes.

    2016-03-01

    Sleep apnea (SA) is increasing in prevalence and is commonly comorbid with hypertension. Chronic intermittent hypoxia is used to model the arterial hypoxemia seen in SA, and through this paradigm, the mechanisms that underlie SA-induced hypertension are becoming clear. Cyclic hypoxic exposure during sleep chronically stimulates the carotid chemoreflexes, inducing sensory long-term facilitation, and drives sympathetic outflow from the hindbrain. The elevated sympathetic tone drives hypertension and renal sympathetic activity to the kidneys resulting in increased plasma renin activity and eventually angiotensin II (Ang II) peripherally. Upon waking, when respiration is normalized, the sympathetic activity does not diminish. This is partially because of adaptations leading to overactivation of the hindbrain regions controlling sympathetic outflow such as the nucleus tractus solitarius (NTS), and rostral ventrolateral medulla (RVLM). The sustained sympathetic activity is also due to enhanced synaptic signaling from the forebrain through the paraventricular nucleus (PVN). During the waking hours, when the chemoreceptors are not exposed to hypoxia, the forebrain circumventricular organs (CVOs) are stimulated by peripherally circulating Ang II from the elevated plasma renin activity. The CVOs and median preoptic nucleus chronically activate the PVN due to the Ang II signaling. All together, this leads to elevated nocturnal mean arterial pressure (MAP) as a response to hypoxemia, as well as inappropriately elevated diurnal MAP in response to maladaptations. PMID:26838032

    1998-07-01

    We describe 10 cases of sacral fractures diagnosed within the rheumatology department at Southend Hospital over the last 5 yr. All presented with sudden-onset low back pain. The majority were elderly, frail, with chronic inflammatory disease (six with rheumatoid arthritis, one with polymyalgia rheumatica, one with vasculitis) and had received steroids. Diagnosis was delayed by the inability of plain radiographs to show these fractures and was ultimately demonstrated by technetium scintigraphy/computed tomography scan. We feel that this diagnosis should be considered in elderly patients with rheumatoid arthritis or other risk factors for osteoporosis who present with low back pain and sacral tenderness. Further clues may be parasymphyseal tenderness (suggesting associated pubic ramus fracture), elevated alkaline phosphatase and plain radiograph showing pubic ramus fractures or parasymphyseal sclerosis. Patients with this complication generally have a poor prognosis and two of our patients have died. Seven required in-patient stay (mean 20 days; range 14-41). The mortality, morbidity and costs incurred in management may be comparable to those of femoral neck fractures. PMID:9714359

  19. Sacral-neuromodulation CT-guided

    International Nuclear Information System (INIS)

    Purpose: Sacral neuromodulation is a new treatment for refractory voiding disorders such as urge incontinence, urinary retention, frequency-urgency syndromes and faecal incontinence. The current approach to sacral nerve stimulation consists of a two-stage procedure. The first is a PNE test (Percutaneous Nerve Evaluation) by a provisional electrically stimulated spinal needle, placed percutaneously in the S3 foramina for four of ten days. If successful, the second stage, permanent implantation, is carried out. The PNE test is performed under fluoroscopic control using the palpable bony sacral foramina as referral points. This technique can show some limitations, such as operator Rx exposure, poor visualization of sacral foramina because of bowel gas artefacts or sacral malformation. In order to reduce these inconveniences and to improve efficiency of the test we tried an alternative technique. The purpose of our study was to test the use of CT as an alternative technique in order to evaluate its advantages and possible routine use. Materials and methods: We tested 30 patients with the PNE test under CT guidance (16 males and 14 females) suffering from serious pelvic disorders and not responding to the normal therapeutic regime. Twenty-seven patient showed relative anatomical integrity of the pelvis and the sacrum, the remaining 3 patients presented morphological anormalities of the sacral foramina. With the patient in the prone position the sacral foramina were identified with CT volumetric scanning using a spiral CT scanner equipped with a second console for the three-dimensional reconstructions. Having identified the location of the S3 foramina, a sterile field was prepared and the spiral needle introduced checking correct positioning with a CT control scan. An electrode was inserted after having checked correct muscular contractile response and the precise position with a further CT scan. Results: Thirty patients were subjected to PNE under CT guidance for a

    Full Text Available Background: The sacrum is a large triangular bone formed by the fusion of the five sacral vertebrae and forms the caudal region of the vertebral column. Aims: This was aimed at studying the morphometry of the sacral hiatus noting its anatomical variations that is useful in caudal epidural anaesthesia. Materials and Methods: Eighty three intact adult sacra of unknown sex were measured with vernier callipers and the various shapes of the sacral hiatus were also noted. Results: The findings revealed that inverted U (48.2% was the most predominant shape; followed by inverted V (34.9%, dumbbell (4.8%, bifid (4.8% and irregular (4.8%. The mean anteroposterior diameter at the apex was 5.52 ± 1.89mm. The mean length of the sacral hiatus was 20.05 ± 9.22mm and the transverse width at base of hiatus was 12.35 ± 3.12mm. There was complete spina bifida in 1.2% and absence of sacral hiatus in another 1.2%. Conclusion: The knowledge of anatomical variations of sacral hiatus is important in the administration of caudal epidural anaesthesia in the studied population and may help to reduce its failure rate.

    Experiments to investigate restoration of lower urinary tract control by electrical stimulation of the sacral nerve roots are mostly performed on dogs, yet little morphometric data (such as canine root and fiber diameter distributions) are available. The aim of this study was to acquire morphometric data of the intradural canine sacral dorsal and ventral roots (S1-S3). Cross-sections of sacral roots of two beagle dogs were analyzed using a light microscope and image processing software. The cross-sectional area of each root was measured. The diameters of the fibers and the axons in the cross-sections of the S2 and S3 roots were measured and used to construct nerve fiber diameter frequency distribution histograms. The results show a unimodal diameter distribution for the dorsal roots and a bimodal distribution for the ventral roots. In addition the average ratio g of the axon diameter to fiber diameter was calculated for each root. PMID:8732990

    Full Text Available We report an unusual case of unilateral limb pseudo hypertrophy in a 21-year-old lady who developed progressive enlargement of the right calf followed by thigh in association with chronic leg pain. Magnetic resonance imaging (MRI of the affected limb confirmed enlargement of various muscles. Electromyography revealed neurogenic features consistent with S1 radiculopathy. MRI of the lumbosacral spine showed tethered cord with a lipoma infiltrating multiple sacral roots. Our case illustrates that muscular pseudo hypertrophy may follow chronic denervation as a consequence of spinal neural compressive disease. The various mechanisms postulated for this distinct condition are outlined.

    2011-01-01

    Summary Lumbosacral epidural abscesses are managed either conservatively with IV antibiotics or with open surgery, particularly in the presence of acute neurological symptoms. Their location makes it difficult for image-guided interventional approaches either for biopsy or evacuation. We report the sacral hiatus and canal as a corridor for image-guided minimally invasive abscess of lumbosacral epidural abscess for aspiration. A 56-year-old man presented to the emergency department complaining of six weeks of worsening low back pain. MRI of the patient’s lumbosacral spine showed osteomyelitis involving his L5, S1 vertebrae, L5-S1 discitis, as well as an anterior epidural abscess extending from L4-5 disc space to the S2 vertebral level. Blood cultures grew out gram-positive cocci. For drainage, a 5-French micropuncture kit was utilized to access the hiatus. Under fluoroscopic guidance a microwire was then advanced along the sacral canal. An 18-gauge needle curved to approximate the contours of the sacral canal was then advanced over the guidewire. Once anatomic access was established 2 ml of thick purulent material was aspirated. The patient tolerated the procedure well, and no focal nerve root symptoms were noted following the procedure. Image-guided aspiration of lumbosacral epidural abscesses can thus be carried out in a safe and effective manner using a sacral hiatus approach. PMID:22192554

    Nesfatin is a peptide secreted by peripheral tissues, central and peripheral nervous system. It is involved in the regulation of homeostasis. Although the effects of nesfatin-1 on nutrition have been studied widely in the literature, the mechanisms of nesfatin-1 action and also relations with other physiological parameters are still not clarified well. We aimed to investigate the effect of peripheral chronic nesfatin-1 application on blood pressure regulation in normal and in rats exposed to restraint immobilization stress. In our study, three month-old male Wistar rats were used. Rats were divided into 4 groups as Control, Stress, Control+Nesfatin-1, Nesfatin-1+Stress. Angiotensinogen, angiotensin converting enzyme 2, angiotensin II, endothelin-1, endothelial nitric oxide synthase, aldosterone, cortisol, nesfatin-1 levels were determined in plasma samples by ELISA. Our results have shown that chronic peripheral nesfatin-1 administration increases blood pressure in normal and in rats exposed to chronic restraint stress. Effect of nesfatin-1 on circulating level of angiotensinogen, angiotensin converting enzyme 2, angiotensin II, endothelin-1, endothelial nitric oxide synthase, aldosterone and cortisol has been identified. We can conclude that elevated high blood pressure after chronic peripheral nesfatin-1 administration in rats exposed to chronic restraint stress may be related to decreased plasma level of endothelial nitric oxide synthase concentration.

    Choi, Seyoung; Lee, Minsun; Kwon, Byongan

    2014-01-01

    Individual pelvic sacral angle was measured, compared and analyzed for the 6 male and female adults who were diagnosed with lumbar spinal stenosis, foraminal stenosis and mild spondylolisthesis in accordance with spinal parameters, pelvic parameters and occlusion state of sacroiliac joint presented by the author of this thesis based on the fact that the degree of lumbar excessive lordosis that was one of the causes for lumbar pain was determined by sacral slope. The measured values were compared with the standard values of the average normal range from 20 s to 40 s of normal Koreans stated in the study on the change in lumbar lordosis angle, lumbosacral angle and sacral slope in accordance with the age by Oh et al. [5] and sacral slope and pelvic sacral slope of each individual of the subjects for measurement were compared. Comparing the difference between the two tilt angles possessed by an individual is a comparison to determine how much the sacroiliac joint connecting pelvis and sacral vertebrae compensated and corrected the sacral vertebrae slope by pelvic tilt under the condition of synarthrodial joint.Under the condition that the location conforming to the line in which the sagittal line of gravity connects with pelvic ASIS and pubic pubic tuberele is the neutral location of pelvic tilt, sacral slope being greater than pelvic sacral slope means pelvic anterior tilting, whereas sacral slope being smaller than pelvic sacral slope means pelvic posterior tilting. On that account, male B, female A and female C had a pelvic posterior tilting of 16 degrees, 1 degree and 5 degrees respectively, whereas male A, male C and female B had a pelvic anterior tilting of 3 degrees, 9 degrees and 4 degrees respectively. In addition, the 6 patients the values of lumbar lordosis angle, lumbosacral angle and sacral slope that were almost twice as much as the normal standard values of Koreans. It is believed that this is because the pelvic sacral slope maintaining an angle that is

    The presence of cysts within the sacral spinal canal, so-called sacral cysts, is described in literature. These include 'sacral perineural cyst', 'sacral extradural cyst', 'occult intrasacral meningocele' and 'anterior sacral meningocele'. Sacral perineural cyst in these cystic disorders was first described as an incidental autopsy finding by Tarlov in 1938. Since then, several reports have been made describing the sign and symptom, neurological findings, roentgenographic diagnosis and cause and origin of the sacral perineural cysts, although many problems are not yet solved satisfactorily. This cyst occurs on the extradural components of sacral or coccygeal nerve roots. Although most are asymptomatic, these occasionally cause low back pain, sciatic and sacrococcygeal pain, sensory and motor disturbance in the lower extremities, and urinary dysfunction, which symptoms are similar to those brought on by lumbar disc herniation. In 1948, Tarlov reported a case of sciatic pain due to a perineural cyst, the removal of which relieved the symptoms. Symptoms occur because adjacent nerve roots are impinged upon by the thin-walled, fluid-filled cysts, which are formed in a space between the endoneurium and the perineurium. Microscopically, the cyst walls consist of peripheral nerve fibers or ganglionic cells covered with meningeal epithelium. Communication of the cyst with subarachnoid cerebrospinal fluid may be poor, but myelogram and CT myelogram demonstrate the cysts filling with contrast media. With the advent of magnetic resonance imaging (MRI), imaging of the sacral perineural cysts has improved. Recently we had the opportunity to evaluate a patient in whom perineural cysts had caused considerable erosion of the sacrum.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3221973

    Pain caused by tumor infiltration of the sacral area remains a major clinical challenge. Patients with poor pain control despite comprehensive medical management may be treated with neuraxial techniques such as continuous epidural or spinal anesthetic. We report a case in which a patient with metastatic breast cancer experienced inadequate pain relief after multiple intravenous pain management regimens as well as intrathecal (IT) drug delivery. The concentration of local anesthetics delivered via the IT catheter was limited due to the patient's baseline motor weakness which would be exacerbated with higher concentrations of local anesthetics. Thus, a decision was made to insert an epidural catheter via a retrograde technique to provide the patient with a "band of anesthesia" which would provide profound sensory blockade without concomitant motor weakness. Pain refractory to other modalities of pain control was successfully treated with the epidural technique. PMID:27162431

    Lumbosacral osteomyelitis and discitis are usually a result of hematogenous spread; rarely it can result from direct inoculation during a surgical procedure. Bacteria may also track along implanted devices to a different location. This is a rare complication seen from pelvic organ prolapse surgery with sacral colpopexy. A 67-year-old female developed increasing lower back pain four months following a laparoscopic sacral colpopexy. Imaging revealed lumbar 5-sacral 1 (L5-S1) osteomyelitis and discitis with associated phlegmon confirmed by percutaneous biopsy and culture. The patient was treated conservatively with antibiotics, but required laparoscopic removal of the pelvic and vaginal mesh followed by twelve weeks of intravenous antibiotics. The patient has experienced clinical improvement of her back pain. This is an uncommon complication of sacral colpopexy, but physicians must be vigilant and manage aggressively to avoid more serious complications and permanent deficit. PMID:27551651

    Full Text Available A 76-year-old man presented with a Denis Zone III sacral fracture after a traffic accident. He also developed urinary retention and perineal numbness. The patient was diagnosed with neurogenic bladder dysfunction caused by the sacral fracture. A computed tomogram (CT revealed that third sacral lamina was fractured and displaced into the spinal canal, but vertebral body did not displace. The fracture lines began at the center of lamina and extended bilateraly. The fracture pattern was unique. The sacrum was osteoporosis, and this fracture may be based on osteoporosis. We performed laminectomy to decompress sacral nerve roots. One month after surgery, the patient was able to urinate. Three months after surgery, his bladder function recovered normally. One year after surgery, he returned to a normal daily life and had no complaints regarding urination. One-year postoperative CT showed the decompressed third sacrum without displacement.

  14. A sacral lesion resembling osteochondrosis in the German Shepherd dog

    International Nuclear Information System (INIS)

    More than 30% (21 of 65) of German Shepherd dogs with clinical signs of cauda equina compression had radiographic and pathologic abnormalities compatible with osteochondrosis of the sacral endplate. Most of these dogs had a defect in the dorsal part of the sacral endplate and a detached bone fragment in the vertebral canal. Similar lesions were also found in growing and young adult dogs without clinical signs. The dogs with clinical signs of cauda equina compression also had severe degenerative disc disease with protrusion of the lumbosacral disc and compression of the cauda equina, suggesting that the signs of cauda equina compression more likely were related to the secondary degenerative changes (disc protrusions) rather than the primary disease. Clinically normal German Shepherds with sacral osteochondrosis usually were younger than 18 months, the dogs with cauda equina compression and sacral osteochondrosis older than 18 months (mean age 4.8 years). On the average, these dogs were two years younger as compared to dogs with cauda equina compression without sacral osteochondrosis. Male dogs are more often affected than females (5:1). There is a breed predisposition: in dogs other than German Shepherds, osteochondrosis of the sacral endplate seems to be extremely rare

    2014-02-01

    Perineurial cysts (Tarlov cysts) are lesions of the nerve root that are often observed in the sacral area. There is debate about whether symptomatic perineurial cysts should be treated surgically. We presented three patients with symptomatic perineurial cyst who were treated surgically, and introduced sacral recapping laminectomy. Patients complained of low back pain and hypesthesia on lower extremities. We performed operations with sacral recapping technique for all three. The outcome measure was baseline visual analogue score and post operative follow up magnetic resonance images. All patients were completely relieved of symptoms after operation. Although not sufficient to address controversies, this small case series introduces successful use of a particular surgical technique to treat sacral perineural cyst, with resolution of most symptoms and no sequelae.

  16. Chronic changes of hematocrit value alter blood pressure and glomerular filtration in spontaneously hypertensive rats

    2012-01-01

    Full Text Available Many studies in hypertensive humans and animals have shown that increased blood viscosity is in direct relation with essential hypertension. The aim of our studies was to investigate the effects of chronic hematocrit value changes on arterial blood pressure and kidney function in genetically induced hypertension. To this end, we studied the effects of several interventions, designed to increase/decrease hematocrit, on hemodynamic parameters, vascular reactivity, glomerular filtration and renal function curve in spontaneously hypertensive rats (SHR. Results of our study show that chronic hematocrit value elevation increases blood pressure and peripheral vascular resistance in SHR. On the other hand, chronic hematocrit lowering elucidates blood pressure and peripheral vascular resistance decrease followed by cardiac output rising. Both hematocrit value changes significantly reduce vasodilatory vascular response. Hematocrit lowering induces acute renal failure. Sodium excretion is shifted to higher blood pressure values in high hematocrit value animals and opposite - lower blood pressure values in low hematocrit value animals. Repeated transfusions develop salt sensitive malignant hypertension in SHR. Further studies are necessary to evaluate the degree of kidney damage after chronic hematocrit value changes in SHR.

    AIMS: In chronic renal failure, the clearance of most ACE inhibitors including enalapril is reduced. Hence, with conventional dosage, plasma enalaprilat may be markedly elevated. It is unclear whether this excess of drug exposure affords an improved control of blood pressure. The aim of the present...... study was to evaluate short-term blood pressure response to two different plasma levels of enalaprilat. METHODS: As part of an open, randomized, controlled trial of the effect of high and low dosage of enalapril on the progression of renal failure, short-term blood pressure response was evaluated. Data...... potassium concentrations at day 90 and patients in the low group experienced a slight increase in GFR. CONCLUSIONS: In moderate to severe chronic renal insufficiency the same degree of blood pressure control was achieved on low as well as moderate daily doses of enalapril. This was irrespective of...

    2016-06-01

    Sacral insufficiency fractures (SIFs) are a common cause of back pain in the elderly. SIFs mimic the symptoms of lumbar spine pathology and so are commonly missed or underdiagnosed. Here we present four cases of missed SIFs that were subsequently identified and treated. One patient was treated as mechanical lower back ache, another patient underwent root block and two patients underwent surgery for lumbar canal stenosis. None experienced relief of their symptoms after these procedures. Retrospective analysis of X-ray and magnetic resonance imaging data revealed SIFs that were confirmed by computed tomography scans. All four patients were treated for underlying osteoporosis. Two patients who underwent surgery were treated conservatively and other two were treated by sacroplasty involving injection of cement into the fracture. Sacroplasty produced immediate pain relief and early mobilization compared to the conservative group. SIFs should always be considered in the differential diagnosis of an elderly patient presenting with low back symptoms. Sacroplasty can be considered for immediate pain relief and rapid mobilization.

  2. Cauda equina syndrome presentation of sacral insufficiency fractures

    International Nuclear Information System (INIS)

    Sacral insufficiency fractures are a well recognised cause for low back, buttock and groin pain in the elderly. However, over a 4 year period, four patients have presented with symptoms of cauda equina syndrome, who were found on investigation to have acute sacral insufficiency fracture without any other aetiological spinal abnormality. Four patients who presented to the spinal surgeons of our institution with symptoms of cauda equina syndrome were referred for spinal MR. Sagittal and axial T1 and T2 weighted turbo spin echo sequences of the lower thoracic and lumbar spine were performed on all patients. Subsequent studies included MR of the sacrum supplemented where appropriate by CT and technetium MDP bone scintigraphy. No evidence of a compressive lesion of the lower thoracic or lumbar spine was present in any of the four patients. Dedicated MR examination of the sacrum in these patients revealed unilateral acute insufficiency fractures involving zone 1 from S1 to S3 extending from the sacro-iliac joint to the lateral margin of the sacral foramen. There was no evidence of compression of the sacral nerve roots. The possible mechanism for the symptomatic presentation is discussed. Sacral insufficiency fractures should be excluded in elderly or osteoporotic patients presenting with cauda equina syndrome who have no evidence of compression in the thoraco-lumbar MR studies.

  3. Biochemical association of metabolic profile and microbiome in chronic pressure ulcer wounds.

    Directory of Open Access Journals (Sweden)

    Mary Cloud B Ammons

    Full Text Available Chronic, non-healing wounds contribute significantly to the suffering of patients with co-morbidities in the clinical population with mild to severely compromised immune systems. Normal wound healing proceeds through a well-described process. However, in chronic wounds this process seems to become dysregulated at the transition between resolution of inflammation and re-epithelialization. Bioburden in the form of colonizing bacteria is a major contributor to the delayed headlining in chronic wounds such as pressure ulcers. However how the microbiome influences the wound metabolic landscape is unknown. Here, we have used a Systems Biology approach to determine the biochemical associations between the taxonomic and metabolomic profiles of wounds colonized by bacteria. Pressure ulcer biopsies were harvested from primary chronic wounds and bisected into top and bottom sections prior to analysis of microbiome by pyrosequencing and analysis of metabolome using 1H nuclear magnetic resonance (NMR spectroscopy. Bacterial taxonomy revealed that wounds were colonized predominantly by three main phyla, but differed significantly at the genus level. While taxonomic profiles demonstrated significant variability between wounds, metabolic profiles shared significant similarity based on the depth of the wound biopsy. Biochemical association between taxonomy and metabolic landscape indicated significant wound-to-wound similarity in metabolite enrichment sets and metabolic pathway impacts, especially with regard to amino acid metabolism. To our knowledge, this is the first demonstration of a statistically robust correlation between bacterial colonization and metabolic landscape within the chronic wound environment.

  4. Bone scan demonstration of progression of sacral insufficiency stress fracture

    International Nuclear Information System (INIS)

    This case documents the progression of a sacral insufficiency stress fracture, initially involving the lateral left ala and later extending across the body of the sacrum to the right ala. A bone scan was performed using technetium-99. The H shaped distribution of increased uptake on radionuclide bone scanning is characteristic of this type of fracture, although variations of this pattern are also seen according to the severity of the sacral trauma. While the differing bone scan patterns of this particular fracture type are well established, this case demonstrates this progression on bone scan (and CT) from, initially, uptake in a single sacral ala to the characteristic H-shaped increased uptake on a later scan. 4 refs., 4 figs

  5. Evaluation of negative pressure vacuum-assisted system in acute and chronic wounds closure: our experience.

    Science.gov (United States)

    Chiummariello, S; Guarro, G; Pica, A; Alfano, C

    2012-10-01

    Negative-pressure therapy or vacuum-assisted closure (VAC) has been used in clinical applications since the 1940's and has increased in popularity over the past decade. This dressing technique consists of an open cell foam dressing put into the wound cavity, a vacuum pump produces a negative pressure and an adhesive drape. A controlled sub atmospheric pressure from 75 to 150 mmHg is applied. The vacuum-assisted closure has been applied by many clinicians to chronic wounds in humans; however it cannot be used as a replacement for surgical debridement. The initial treatment for every contaminated wound should be the necrosectomy. The VAC therapy has a complementary function and the range of its indications includes pressure sores, stasis ulcers, chronic wounds such as diabetic foot ulcers, post traumatic and post operative wounds, infected wounds such as necrotizing fasciitis or sternal wounds, soft-tissue injuries, bone exposed injuries, abdominal open wounds and for securing a skin graft. We describe our experience with the VAC dressing used to manage acute and chronic wounds in a series of 135 patients, with excellent results together with satisfaction of the patients. PMID:23095568

  6. Acute and chronic effects of aerobic and resistance exercise on ambulatory blood pressure

    Directory of Open Access Journals (Sweden)

    Crivaldo Gomes Cardoso Jr

    2010-01-01

    Full Text Available Hypertension is a ubiquitous and serious disease. Regular exercise has been recommended as a strategy for the prevention and treatment of hypertension because of its effects in reducing clinical blood pressure; however, ambulatory blood pressure is a better predictor of target-organ damage than clinical blood pressure, and therefore studying the effects of exercise on ambulatory blood pressure is important as well. Moreover, different kinds of exercise might produce distinct effects that might differ between normotensive and hypertensive subjects. The aim of this study was to review the current literature on the acute and chronic effects of aerobic and resistance exercise on ambulatory blood pressure in normotensive and hypertensive subjects. It has been conclusively shown that a single episode of aerobic exercise reduces ambulatory blood pressure in hypertensive patients. Similarly, regular aerobic training also decreases ambulatory blood pressure in hypertensive individuals. In contrast, data on the effects of resistance exercise is both scarce and controversial. Nevertheless, studies suggest that resistance exercise might acutely decrease ambulatory blood pressure after exercise, and that this effect seems to be greater after low-intensity exercise and in patients receiving anti-hypertensive drugs. On the other hand, only two studies investigating resistance training in hypertensive patients have been conducted, and neither has demonstrated any hypotensive effect. Thus, based on current knowledge, aerobic training should be recommended to decrease ambulatory blood pressure in hypertensive individuals, while resistance exercise could be prescribed as a complementary strategy.

  7. Elevated pulse pressure is associated with hemolysis, proteinuria and chronic kidney disease in sickle cell disease.

    Directory of Open Access Journals (Sweden)

    Enrico M Novelli

    Full Text Available A seeming paradox of sickle cell disease is that patients do not suffer from a high prevalence of systemic hypertension in spite of endothelial dysfunction, chronic inflammation and vasculopathy. However, some patients do develop systolic hypertension and increased pulse pressure, an increasingly recognized major cardiovascular risk factor in other populations. Hence, we hypothesized that pulse pressure, unlike other blood pressure parameters, is independently associated with markers of hemolytic anemia and cardiovascular risk in sickle cell disease. We analyzed the correlates of pulse pressure in patients (n  =  661 enrolled in a multicenter international sickle cell trial. Markers of hemolysis were analyzed as independent variables and as a previously validated hemolytic index that includes multiple variables. We found that pulse pressure, not systolic, diastolic or mean arterial pressure, independently correlated with high reticulocyte count (beta  =  2.37, p  =  0.02 and high hemolytic index (beta  =  1.53, p = 0.002 in patients with homozygous sickle cell disease in two multiple linear regression models which include the markers of hemolysis as independent variables or the hemolytic index, respectively. Pulse pressure was also independently associated with elevated serum creatinine (beta  =  3.21, p  =  0.02, and with proteinuria (beta  =  2.52, p  =  0.04. These results from the largest sickle cell disease cohort to date since the Cooperative Study of Sickle Cell Disease show that pulse pressure is independently associated with hemolysis, proteinuria and chronic kidney disease. We propose that high pulse pressure may be a risk factor for clinical complications of vascular dysfunction in sickle cell disease. Longitudinal and mechanistic studies should be conducted to confirm these hypotheses.

  8. Pubic and sacral insufficiency fractures: clinical course and radiologic findings

    International Nuclear Information System (INIS)

    Distinctive vertical insufficiency fractures of the pelvis were found in nine osteopenic patients. Each patient had subacute pelvic pain without antecedent trauma. The sacral fractures healed fairly quickly, but the pubic fractures often had a protracted course. All nine patients had skeletal demineralization due to metabolic bone disease, radiation therapy, or multiple myeloma. Recognition of the association between public and sacral insufficiently fractures should aid in recognizing the diffuse nature of the skeletal disease so that unnecessary biopsy of the fracture sites can be avoided. Plain films, tomographic scans, and radionuclide bone scans are reviewed

    Previous studies suggest that high airway pressure may compromise cardiac output. We investigated the effect of 3 nasal continuous positive airway pressure levels on cardiac output in preterm infants with evolving chronic lung disease. We found that brief changes in continuous positive airway pressure did not affect cardiac output. PMID:25454930

    In a 41-year old woman complaining of episodic bilateral sciatic pain, MRI showed large sacral cysts developed in the pelvis. The fact that these cysts communicated with the subarachnoidal spaces was not clearly demonstrated by CT. The mechanism underlying the development of this perineural variety of extradural cysts is discussed. PMID:1439457

    Preliminary results are presented for a study aimed at a quantitative comparison of microvascular dynamics in second-generation rats reared in a 2-g force field produced by centrifugation with similar data from animals reared in a centrifuge that produced only a 1-g force. It is shown that the pressure distribution in the mesenteric microvasculature of the second generation of rats reared in a 2-g environment, as well as the animals' blood pressure response to epinephrine, are significantly different compared to their 1-g counterparts. In particular, 1-g and 2-g chronic centrifugation enhances the arterial blood pressure, and the 2-g force field attenuates the pressor effects of norepinephrine.

    The development of bladder and bowel neuroprostheses may benefit from the use of sensory feedback. We evaluated the use of high-density penetrating microelectrode arrays in sacral dorsal root ganglia (DRG) for recording bladder and perineal afferent activity. Arrays were inserted in S1 and S2 DRG in three anesthetized cats. Neural signals were recorded while the bladder volume was modulated and mechanical stimuli were applied to the perineal region. In two experiments, 48 units were observed that tracked bladder pressure with their firing rates (79% from S2). At least 50 additional units in each of the three experiments (274 total; 60% from S2) had a significant change in their firing rates during one or more perineal stimulation trials. This study shows the feasibility of obtaining bladder-state information and other feedback signals from the pelvic region with a sacral DRG electrode interface located in a single level. This natural source of feedback would be valuable for providing closed-loop control of bladder or other pelvic neuroprostheses.

    Low back pain, sciatia or perineal chronic pain are sometimes related to perineural sacral cysts. Surgical treatment is difficult and may lead to pain or neurological worsening. We report four cases of symptomatic perineural cysts; three of them where operated on with two good results and one increasing perineal pain. Anatomical and radiological description are reviewed. From a therapeutical point of view, we can distinguish two clinical types of radicular suffering. Perineural cyst can cause a commun radicular extrinsic compression; in such a case surgical operation will improve radicular pain. The cystic nerve root can present an intrinsic suffering because of on intradural dilaceration. Then surgery must be avoided specially when many roots are involved because it may worsen the pluriradicular suffering. PMID:9686226

  20. Sacral Fracture Nonunion Treated by Bone Grafting through a Posterior Approach

    Full Text Available Nonunion of a sacral fracture is a rare but serious clinical condition which can cause severe chronic pain, discomfort while sitting, and significant restriction of the level of activities. Fracture nonunions reportedly occur most often after nonoperative initial treatment or inappropriate operative treatment. We report a case of fracture nonunion of the sacrum and pubic rami that resulted from non-operative initial treatment, which was treated successfully using bone grafting through a posterior approach and CT-guided percutaneous iliosacral screw fixation combined with anterior external fixation. Although autologous bone grafting has been the gold standard for the treatment of pelvic fracture nonunions, little has been written describing the approach. We utilized a posterior approach for bone grafting, which could allow direct visualization of the nonunion site and preclude nerve root injury. By this procedure, we were able to obtain the healing of fracture nonunion, leading to pain relief and functional recovery.

    Chronic pressure ulcers (PrUs), ulcers that fail to progress through the expected phases of wound healing in a timely fashion, are not only a concern for the patients afflicted with them, but are also a significant burden for the long-term-care facilities in which patients reside. The heel is the second most common location for PrUs. Morbidity and mortality rates for heel PrUs, particularly in the diabetic population, are alarming. Therefore, a consistently effective, cost-conscious, and user-friendly topical treatment for heel ulcers would be welcomed by patients and clinicians. This article describes a marked and rapid improvement in wound granulation in 3 older adult patients following weekly treatment for 8 weeks of chronic (≥1-year duration) heel ulcers with an easy-to-use, cost-effective, topical, formulated collagen gel.

    Chronic ankle instability (CAI) patients have been shown to have increased lateral column plantar pressure throughout the stance phase of gait. To date, traditional CAI rehabilitation programs have been unable to alter gait. We developed an auditory biofeedback device that can be worn in shoes that elicits an audible cue when an excessive amount of pressure is applied to a sensor. This study determined whether using this device can decrease lateral plantar pressure in participants with CAI and alter surface electromyography (sEMG) amplitudes (anterior tibialis, peroneus longus, medial gastrocnemius, and gluteus medius). Ten CAI patients completed baseline treadmill walking while in-shoe plantar pressures and sEMG were measured (baseline condition). Next, the device was placed into the shoe and set to a threshold that would elicit an audible cue during each step of the participant's normal gait. Then, participants were instructed to walk in a manner that would not trigger the audible cue, while plantar pressure and sEMG measures were recorded (auditory feedback (AUD FB) condition). Compared to baseline, there was a statistically significant reduction in peak pressure in the lateral midfoot-forefoot and central forefoot during the AUD FB condition. In addition, there were increases in peroneus longus and medial gastrocnemius sEMG amplitudes 200ms post-initial contact during the AUD FB condition. The use of this auditory biofeedback device resulted in decreased plantar pressure in the lateral column of the foot during treadmill walking in CAI patients and may have been caused by the increase in sEMG activation of the peroneus longus.

    Home blood pressure monitoring (HBPM) is recommended in patients with chronic kidney disease (CKD) and hypertension (HTN). However, little is known about the use and pattern of HBPM in CKD patients. A cross-sectional study was conducted in an out-patient nephrology clinic. A total of 285 patients participated in the study. Of all patients, 66% reported using HBPM. Self-reported compliance with BP medications (93.9% vs. 85.1%, p 0.03), exercise >3 days/week (45.9 vs. 26.3%, p helpful in managing hypertension (85.4%). Most common reason for not using HBPM was lack of advice by a physician (43.4%). HBPM use is common in patients with CKD and HTN. HBPM users are more likely to follow life-style and dietary modifications for blood pressure control. PMID:27104796

  4. Update: Non-Invasive Positive Pressure Ventilation in Chronic Respiratory Failure Due to COPD.

    2016-01-01

    Long-term non-invasive positive pressure ventilation (NPPV) has widely been accepted to treat chronic hypercapnic respiratory failure arising from different etiologies. Although the survival benefits provided by long-term NPPV in individuals with restrictive thoracic disorders or stable, slowly-progressing neuromuscular disorders are overwhelming, the benefits provided by long-term NPPV in patients with chronic obstructive pulmonary disease (COPD) remain under question, due to a lack of convincing evidence in the literature. In addition, long-term NPPV reportedly failed in the classic trials to improve important physiological parameters such as arterial blood gases, which might serve as an explanation as to why long-term NPPV has not been shown to substantially impact on survival. However, high intensity NPPV (HI-NPPV) using controlled NPPV with the highest possible inspiratory pressures tolerated by the patient has recently been described as a new and promising approach that is well-tolerated and is also capable of improving important physiological parameters such as arterial blood gases and lung function. This clearly contrasts with the conventional approach of low-intensity NPPV (LI-NPPV) that uses considerably lower inspiratory pressures with assisted forms of NPPV. Importantly, HI-NPPV was very recently shown to be superior to LI-NPPV in terms of improved overnight blood gases, and was also better tolerated than LI-NPPV. Furthermore, HI-NPPV, but not LI-NPPV, improved dyspnea, lung function and disease-specific aspects of health-related quality of life. A recent study showed that long-term treatment with NPPV with increased ventilatory pressures that reduced hypercapnia was associated with significant and sustained improvements in overall mortality. Thus, long-term NPPV seems to offer important benefits in this patient group, but the treatment success might be dependent on effective ventilatory strategies. PMID:26418151

    The induced electric field/current in the sacral nerve by stimulation devices for the treatment of bladder overactivity is investigated. Implanted and transcutaneous electrode configurations are considered. The electric field induced in the sacral nerve by the implanted electrode is largely affected by its surrounding tissues, which is attributable to the variation in the input impedance of the electrode. In contrast, the electric field induced by the transcutaneous electrode is affected by the tissue conductivity and anatomical composition of the body. In addition, the electric field induced in the subcutaneous fat in close proximity of the electrode is comparable with the estimated threshold electric field for pain. These computational findings explain the clinically observed weakness and side effect of each configuration. For the transcutaneous stimulator, we suggest that the electrode contact area be increased to reduce the induced electric field in the subcutaneous fat.

    Plain CT described fairly accurately the anatomy and lesions of the lumbar and sacral spines on their transverse sections. Since hernia of the intervertebral disc could be directly diagnosed by CT, indications of myelography could be restricted. Spinal-canal stenosis of the lumbar spine occurs because of various factors, and CT not only demonstrated the accurate size and morphology of bony canals, but also elucidated thickening of the joints and yellow ligament. CT was also useful for the diagnosis of tumors in the lumbar and sacral spines, visualizing the images of bone changes and soft tissues on the trasverse sections. But the diagnosis of intradural tumors required myelography and metrizamide CT. CT has become important for the diagnosis of spinal and spinal-cord diseases and for selection of the route of surgical arrival.

    Full Text Available Background: Resection of sacral chordomas is challenging. The anatomy is complex, and there are often no bony landmarks to guide the resection. Achieving adequate surgical margins is, therefore, difficult, and the recurrence rate is high. Use of computer navigation may allow optimal preoperative planning and improve precision in tumor resection. The purpose of this study was to evaluate the safety and feasibility of computer navigation-aided resection of sacral chordomas. Methods: Between 2007 and 2013, a total of 26 patients with sacral chordoma underwent computer navigation-aided surgery were included and followed for a minimum of 18 months. There were 21 primary cases and 5 recurrent cases, with a mean age of 55.8 years old (range: 35-84 years old. Tumors were located above the level of the S3 neural foramen in 23 patients and below the level of the S3 neural foramen in 3 patients. Three-dimensional images were reconstructed with a computed tomography-based navigation system combined with the magnetic resonance images using the navigation software. Tumors were resected via a posterior approach assisted by the computer navigation. Mean follow-up was 38.6 months (range: 18-84 months. Results: Mean operative time was 307 min. Mean intraoperative blood loss was 3065 ml. For computer navigation, the mean registration deviation during surgery was 1.7 mm. There were 18 wide resections, 4 marginal resections, and 4 intralesional resections. All patients were alive at the final follow-up, with 2 (7.7% exhibiting tumor recurrence. The other 24 patients were tumor-free. The mean Musculoskeletal Tumor Society Score was 27.3 (range: 19-30. Conclusions: Computer-assisted navigation can be safely applied to the resection of the sacral chordomas, allowing execution of preoperative plans, and achieving good oncological outcomes. Nevertheless, this needs to be accomplished by surgeons with adequate experience and skill.

    Sacral and presacral schwannomas are often found incidentally, because they present with vague symptoms or symptomless. Schwannoma occurring in this area occasionally presents with enormous dimensions, known as a giant schwannoma. The tumor removal is a surgical challenge due to the difficult approach and abundant vascularity. The aim of this study is to review cases of giant sacral schwannomas focusing the surgical management and outcome. Six patients with sacral and presacral schwannoma were treated surgically. The patients included two males and four females, and the mean age was 47.8 years. All patients experienced pain at the time of presentation. The tumors were classified as intraosseous type in one case, dumb-bell type in four cases, and retroperitoneal type in one case. The tumors were removed with a piecemeal subtotal excision in three patients, a partial excision in two patients, and enucleation in one patient. The surgeries were performed by the combination of an anterior and posterior approach in three patients, a posterior approach in two patients, and an anterior approach in one patient. The mean surgical time was 7.8 hrs, and the mean blood loss was 2572 g. The tumor recurred in one patient after the partial excision and was removed completely in a second surgery. No patient, including the patient who underwent the second surgery, presented with pain and obvious neurological deficit at the final follow-up. The surgical treatment of the giant sacral schwannoma with a piecemeal subtotal excision can achieve a good outcome, avoiding unnecessary neurological deficit. PMID:19943815

    Sacral chordomas are rare, slow-growing tumours that are amenable to surgery, but unfortunately often diagnosed late. The aim of the study was to identify presenting symptoms, which may aid diagnosis and reduce the treatment time. Forty-four patients were identified with sacral chordoma between 1989 and 2006. Clinical and pathological records were reviewed retrospectively to elicit the symptoms recorded prior to diagnosis, duration of symptoms, surgical treatment, size of tumour and survival. Eleven patients were excluded, leaving 33 patients in the study group. Thirty-one patients had chordomas arising from the sacrum and two patients from the coccyx. The mean duration of symptoms prior to diagnosis was 120 weeks (2.3 years), with a median of length of 104 weeks (two years) and range of 26 to 416 weeks (0.5 to eight years). The mean maximum tumour size at resection was 8.3 cm, with a mean volume of 614 cm3 (range 9–2,113 cm3). Pain, typically dull and worse with sitting, was the most common presenting symptom in 85% of patients. The classic symptoms of cauda equina (saddle anaesthesia, bladder or bowel dysfunction) occurred in 70% patients (23 patients). Sacral chordoma should be considered in cases of back pain with coccydynia, especially with neurological symptoms. PMID:17205349

    The importance of the sacral pelvic incidence (SPI) in relation to individual variations of sagittal spinal curvature has become well-recognised. We attempted to determine the relationship between SPI and acetabular orientation. The three-dimensional coordinates of 47 homologous points were observed on 51 adult anatomical pelvises (26 female and 25 male). The reference vertical plane was Lewinnek's anterior pelvic plane. 10 angular parameters and 11 linear parameters were defined and calculated. These were expressed both in absolute value (in millimetres) and in "acetabular unit" (relative to the mean value of the right and left acetabular rays). Mean values of the parameters were calculated for all pelvises and according to gender. There were two dominant parameters: the "sacral slope" and the "V pubic angle". "Acetabular tilting" was primarily dependent on the "sacral slope" and its intermediary on the "SPI", while "acetabular anteversion" dependent on the "V pubic angle" via the "angle of prow". It is recommended that positioning of the acetabular cup in total hip arthroplasty relates to anatomical parameters, and to the global sagittal balance of the pelvi-spinal unit. PMID:21279971

    Pelvic ring stability is maintained passively by both the osseous and the ligamentous apparatus. Therapeutic approaches focus mainly on fracture patterns, so ligaments are often neglected. When they rupture along with the bone after pelvic ring fractures, disrupting stability, ligaments need to be considered during reconstruction and rehabilitation. Our aim was to determine the influence of ligaments on open-book injury using two experimental models with body donors. Mechanisms of bone avulsion related to open-book injury were investigated. Open-book injuries were induced in human pelves and subsequently investigated by anatomical dissection and endoscopy. The findings were compared to CT and MRI scans of open-book injuries. Relevant structures were further analyzed using plastinated cross-sections of the posterior pelvic ring. A fragment of the distal sacrum was observed, related to open-book injury. Two ligaments were found to be responsible for this avulsion phenomenon: the caudal portion of the anterior sacroiliac ligament and another ligament running along the ventral surface of the third sacral vertebra. The sacral fragment remained attached to the coxal bone by this second ligament after open-book injury. These results were validated using plastination and the structures were identified. Pelvic ligaments are probably involved in sacral avulsion caused by lateral traction. Therefore, ligaments should to be taken into account in diagnosis of open-book injury and subsequent therapy.

    2015-03-01

    Full Text Available Introduction: The sacrum is a large triangular bone, formed by the fusion of five sacral vertebrae. The opening at the caudal end of sacral canal is known as sacral hiatus. It is formed due to the failure of fusion of laminae of the fifth (occasionally fourth sacral vertebra. Sacrum is one of the bones which exhibit variations and the variation of sacral hiatus is of great clinical significance because it may also leads to mechanical low back pain. Previous works on the morphometrical study on the sacral hiatus is limited, especially in Nepal, Parsa population. The present study was undertaken to help in filling this gap at least to a certain extent and also made an attempt to find out the variations of sacrum. Materials: One hundred dry human sacra were collected from the Department of Anatomy of National medical college & Teaching Hospital, Nepal. Methods & Observations: The morphometrical studies were done, and the parameters (Shape, length, Transverse width & Antero-posterior width of sacral hiatus and level of apex & base of sacral hiatus were measured with the help of divider, the observations were recorded, tabulated & analyzed. Result: The study showed a significant co-relation between anatomical variations of sacral hiatus with the previous studies.

    Previous studies relating Doppler parameters and pulmonary capillary wedge pressures (PCWP) typically exclude patients with severe mitral regurgitation (MR). We evaluated the effects of varying degrees of chronic MR on the Doppler estimation of PCWP. PCWP and mitral Doppler profiles were obtained in 88 patients (mean age 55 +/- 8 years) with severe left ventricular (LV) dysfunction (mean ejection fraction 23% +/- 5%). Patients were classified by severity of MR. Patients with severe MR had greater left atrial areas, LV end-diastolic volumes, and mean PCWPs and lower ejection fractions (each P <.01). In patients with mild MR, multiple echocardiographic parameters correlated with PCWP; however, with worsening MR, only deceleration time strongly related to PCWP. From stepwise multivariate analysis, deceleration time was the best independent predictor of PCWP overall, and it was the only predictor in patients with moderate or severe MR. Doppler-derived early mitral deceleration time reliably predicts PCWP in patients with severe LV dysfunction irrespective of degree of MR.

    Full Text Available Objective The aim of the present study was to evaluate the safety and efficacy of a “Cravat’’ technique for the management of uterine prolapse in patients who want to preserve uterus, involving suspension of the uterus from the sacral promontory by using polypropylene mesh. Materials and Methods A prospective observational study between January 2011 and September 2013 was conducted. Prior to surgery, prolapse assessment was undertaken with Baden-Walker halfway system to grade the degree of prolapse at all sites. Patients with severe uterine prolapse (stage II-IV who want to preserve uterus, were operated with Cravat technique. All patients were evaluated at 2 weeks and 6 weeks after surgery and followed for 6 months. Outcomes were evaluated objectively by vaginal examination using Baden-Walker halfway classification, and subjectively classifying patients as ‘very satisfied’, ‘satisfied’ and ‘not satisfied’ at the 6th month postoperatively. Results Sacral uteropexy was successfully performed by laparoscopy in 32/33 patients (one needed to be converted to laparotomy. Nine patients also had a concurrent procedure as colporaphy anterior, colporaphy posterior or transobturator tape. Postoperative recovery has been uneventful with subjective and objective cure rates were 96.9% and 93.9%, respectively at six month. One recurrence of total prolapse needed to be reoperated and two patients with sacrouteropexy still remained at stage 2 prolapse. There have been no cases of graft exposure, rejection or infection with a median follow-up of 23.9 months. Conclusions Laparoscopic sacral uteropexy with “Cravat technique” was found to be safe and simple procedure.

    The objective was to evaluate the piriformis muscles and their relationship to the sacral nerve roots on T1-weighted MRI in patients with no history or clinical suspicion of piriformis syndrome. Axial oblique and sagittal T1-weighted images of the sacrum were obtained in 100 sequential patients (200 pairs of sacral roots) undergoing routine MRI examinations. The relationship of the sacral nerve roots to the piriformis muscles and piriformis muscle size were evaluated, as were clinical symptoms via a questionnaire. The S1 nerve roots were located above the piriformis muscle in 99.5% of cases (n=199). The S2 nerve roots were located above the piriformis muscle in 25% of cases (n=50), and traversed the muscle in 75% (n=150). The S3 nerve roots were located above the piriformis muscle in 0.5% of cases (n=1), below the muscle in 2.5% (n=5), and traversed the muscle in 97% (n=194). The S4 nerve roots were located below the muscle in 95% (n=190). The piriformis muscles ranged in size from 0.8-3.2 cm, with an average size of 1.9 cm. Nineteen percent of patients had greater than 3 mm of asymmetry in the size of the piriformis muscle, with a maximum asymmetry of 8 mm noted. The S1 nerve roots course above the piriformis muscle in more than 99% of patients. The S2 roots traverse the piriformis muscle in 75% of patients. The S3 nerve roots traverse the piriformis muscle in 97% of patients. Piriformis muscle size asymmetry is common, with muscle asymmetry of up to 8 mm identified. (orig.)

    Full Text Available BACKGROUND This study evaluates the advantage of Negative Pressure Wound Therapy-Vacuum Assisted Closure over Conventional Dressing in the management of chronic non-healing ulcers. METHODS From June 2014 to June 2015, 50 patients were selected (25 cases and 25 controls. After wound debridement, VAC dressing is applied. Pre VAC and post VAC culture and sensitivity is taken. Dressing is given for 72 hours and intermittent suction is given for 10 mins. in an hour, daily for 12 hours with negative pressure ranging from 100 to 125 mmHg. Rest of the time drain of the VAC dressing is connected to the Romovac suction drain. Doppler study to assess the vascularity of the limb before the procedure and X-ray is taken to rule out osteomyelitis. Control group patients are given conventional dressings. RESULTS The gender, age and ulcer distributions were almost equal in the case and control groups and were found to be statistically insignificant. Duration of hospital stay in days was found to be statistically significant between groups. Majority (52% of cases left hospital within 3 weeks’ time, while a major chunk (88% of control population stayed more than 3 weeks. VAC dressing shows better results in patients with normal Doppler study. VAC dressing have better results in patients with 48% undergoing split skin grafting and less rate (8% of amputation as against none undergoing split skin grafting and 24% needing amputation in the control group. Patients with sterile pre-VAC culture were not turning unsterile after VAC, but 90% unsterile turns sterile after VAC. CONCLUSION NPWT is a novel technique for managing an open wound by submitting the wound either to intermittent or continuous subatmospheric pressure. Here, we did a study to study the advantage of vacuum assisted closure over conventional dressing in the management of chronic non-healing ulcers and concluded that VAC decreases hospital stay, improves pus culture sterility, has better result in

  9. Extraosseous Ewing's sarcoma / primitive neuroectodermal tumor of the sacral nerve plexus

    International Nuclear Information System (INIS)

    We report an unusual case of Ewing's sarcoma / primitive neuroectodermal tumor (PNET) of the sacral nerve plexus in a 9-year-old boy who presented with a soft tissue swelling and severe piercing pain in the lower back region. MRI of the lumbosacral spine showed a lobulated soft tissue mass with clubbed finger-like projections along the path of the sacral nerves, which had caused widening of the spinal canal and the sacral foramina (S2–S4 level). There was presacral extension and posterior scalloping of the sacral vertebrae. Histopathology of the lesion confirmed Ewing's sarcoma / PNET of the sacral spinal nerve plexus. The patient responded favorably to chemotherapy and radiotherapy, showing clinical and radiological improvement

    Supraphysiological administration of anabolic androgenic steroids has been linked to increased blood pressure. The widely distributed amino acid taurine seems to be an effective depressor agent in drug-induced hypertension. The purpose of this study was to assess the impact of chronic high dose administration of nandrolone decanoate (DECA) and taurine on blood pressure in rats and to verify the potentially involved mechanisms. The study was conducted in 4 groups of 8 adult male Wistar rats, aged 14 weeks, treated for 12 weeks with: DECA (A group); vehicle (C group); taurine (T group), or with both drugs (AT group). Systolic blood pressure (SBP) was measured at the beginning of the study (SBP1), 2 (SBP2) and 3 months (SBP3) later. Plasma angiotensin-converting enzyme (ACE) activity and plasma end products of nitric oxide metabolism (NOx) were also determined. SBP3 and SBP2 were significantly increased compared to SBP1 only in the A group (P<0.002 for both). SBP2, SBP3 and ACE activity showed a statistically significant increase in the A vs C (P<0.005), andvs AT groups (P<0.05), while NOx was significantly decreased in the A and AT groups vs controls (P=0.01). ACE activity was strongly correlated with SBP3 in the A group (r=0.71, P=0.04). These findings suggest that oral supplementation of taurine may prevent the increase in SBP induced by DECA, an effect potentially mediated by angiotensin-converting enzyme. PMID:27254659

    2016-02-01

    Chronic wounds remain a significant medical and financial burden in hospitals of today. A major factor in the transition from an acute to a chronic wound is its bacterial bioburden. Developments in molecular techniques have shown that chronic wounds remain colonised by many species of bacteria and that the bacteria within these chronic wounds exist in two forms. Treatments of chronic wounds have maintained a challenging field and significant ongoing research is being conducted. With the development of an in vitro wound model, we applied topical negative pressure (TNP) dressings to a spectrum of common bacterial biofilms found in chronic wounds and studied the synergistic efficacy between the application of TNP and silver-impregnated foam against these biofilms. This synergistic response was seen within the laboratory strains of staphylococcal biofilms over a 3-day treatment period but lost following the 5 days of treatment. However, combining topical pressure dressings and silver foam lead to a synergistic inactivation in Pseudomonas species over both 3-day and 5-day treatments. PMID:24712658

    This case describes a 46-year-old woman with local pelvic and perineal pain, persisting for 2 years at presentation. The pain worsened during the night and morning and was alleviated during daily activities. Low back pain was associated with morning stiffness lasting longer than 2 h. Sometimes, she felt pain and numbness along her left S1 dermatome, without overt bladder or bowel incontinence. Lasegue's sign was negative. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were elevated (35 mm/h and 9.4, respectively) and Mennel's sign was present on both sides, indicating possible inflammation of the sacroiliac joints. However, radiographs of the lumbosacral spine and sacroiliac joints were normal. Magnetic resonance imaging (MRI) revealed a large spinal meningeal cyst in the sacrum (60 × 37 × 22 mm) consisting of multiple perineural cysts. The cyst eroded the surrounding sacral bone structures, narrowed several sacral foramina, and compressed neighboring nerve fibers. MRI findings on sacroiliac and hip joints were normal.

    Full Text Available Efraim Jaul Skilled Geriatric Nursing Department, Herzog Memorial Hospital, Affiliated to the Hebrew University Hadassah Medical School, Jerusalem, Israel Abstract: The occurrence of pressure ulcers (PUs is common and poses serious problems for the frail elderly, with implications for functional disability and reduced quality of life. PUs are preventable in a majority of cases. The increase in PU occurrence, however, appears regardless of higher awareness in prevention and improvement through utilization of pressure relieving devices. Multiple changes in the elderly body systems occur over time including aging, multiple chronic conditions, and functional impairment, potentially culminating in the final pathways of geriatric syndrome, unless awareness to the development of PUs is reversible and prevented. The assumption is that the development of PUs is based on multifactorial causes (extrinsic and intrinsic factors; thus, the optimal management for elderly patients requires a comprehensive approach in all medical settings (community, hospital, and at the long term care [LTC] level. Comprehensiveness signifies looking beyond the wounds, assisting the patient through both local (wound and systemic (medical condition treatment, using a strategy of prevention and supporting quality of life. Within the multidisciplinary involvement team approach, each professional discipline contributes its own task in coordination with other disciplines to address PU prevention, assessment, and treatment. The entire medical staff and the multidisciplinary team work together and communicate frequently in order to prevent, halt at an early stage, and provide healing in a timely fashion. Limiting the formation of PUs is facilitated through early identification, treating contributing causes, eliminating all unnecessary medications, instituting supportive interventions which include the family.

    Full Text Available Lateral side of each intermediate crest has four dorsal sacral foramina for the passage of posterior division of the sacral nerves. Not only they serve as an important landmark in placement of spinal instrumentation but are also of great importance in transsacral block of sacral nerves for producing analgesia and anesthesia in pelvic surgeries. Therefore a study on the variation in number of dorsal sacral foramina was conducted in 60 adult dry North Indian sacra. Three dorsal sacral foramina were seen on the lateral side of each intermediate crest in four sacra (6.6% and five in 6 sacra (10% amongst all the sacra examined. Either a single pair, double pair or totally absent foramina were not observed in any of the sacra seen. This study revealed that there is variation in the number of dorsal sacral foramina. Anaesthetists should be aware of this disparity to be able to perform trans-sacral nerve block successfully. Radiologists must also know about this variation to interpret the radiographs of lumbosacral region. Neurologist and orthopedist should also be cognizant of this fact to diagnose patients presenting with bizarre clinical findings. [Int J Res Med Sci 2013; 1(3.000: 263-266

    Garre\\'s chronic diffuse sclerosing osteomyelitis (DSOM) is a rare disease that occurs most commonly in the mandible. We present a case of sacral DSOM that simulated an expanding destructive sacral tumour. Treatment was conducted on the basis of the available experience with the mandibular form of the disease, with partial symptomatic relief, but progressive sclerosis of the sacral lesion. To the best of our knowledge, this is the first case initially presenting in the sacrum. As an osteolytic expanding lesion simulating malignancy, it is important to recognize this entity in the sacrum.

    This article describes a novel technique for en bloc resection of locally recurrent rectal cancer that invades the high sacral bone (above S3). The involved segment of the sacrum is mobilised with osteotomes during an initial posterior approach before an anterior abdominal phase where the segment of sacral bone is delivered with the specimen. This allows en bloc resection of the involved sacrum while preserving uninvolved distal and contralateral sacral bone and nerve roots. The goal is to obtain a clear bony margin and offer a chance of cure while improving functional outcomes by maintaining pelvic stability and minimising neurological deficit. PMID:27000857

    A 67-year-old man presented with persistent penis and scrotum pain due to S-2 and S-3 radiculopathy caused by a sacral perineural cyst. The cyst was treated with microsurgical partial cyst removal and cyst wall imbrication, together with closure of the point through which cerebrospinal fluid (CSF) flowed from the subarachnoid space into the cyst cavity. His pain resolved without recurrence of the cyst or complications. Symptomatic perineural cysts are quite rare. Surgical closure of the point through which CSF flows from the subarachnoid space into the cyst cavity is the most important intervention for symptomatic perineural cysts. If the source of CSF leakage cannot be detected, placement of a cyst-subarachnoid shunt should be considered in addition to partial cyst removal and cyst wall imbrication. PMID:22198114

    Vasodilators are used with caution in patients with chronic obstructive pulmonary disease (COPD). We have developed a device for percutaneous arteriovenous shunt creation in the iliac region to increase cardiac output and oxygen delivery for patients with COPD. Although this device does not cause significant blood pressure changes in normotensive patients with COPD, we hypothesized that arteriovenous shunt creation might cause vasodilator effects in hypertensive patients because of a reduction in vascular resistance.

  7. CT-guided fixation of sacral fractures and sacrolilac joint disruptions

    International Nuclear Information System (INIS)

    Placement of sacral fixation screws at surgery is performed blindly (ie, by palpation). The authors of this paper employed CT to localize the screw between the neutral foramina and anterior sacral cortex and to decrease the morbidity associated with general anesthesia and surgery. Six patients underwent CT-guided sacral fixation performed by means of the 7.0 mm A0 cannulated screw system. All patients had reducible vertical sacral fractures or sacroiliac joint disruptions. Following placement of an epidural catheter for anesthesia, patients were scanned in the prone or decubitus position. Measurements for placement of the guide pin were made from the preliminary scans. Following CT confirmation of satisfactory guide pin placement across the fracture, the screw track was drilled, the screw length was determined, and the fixation screw was placed in position. A CT scan was obtained to evaluate the final position of the screw

    Peters, Christian D.; Schou, Uffe K.; Jensen, Jens L.; Magnusson, Nils E.; Ørntoft, Torben F.; Kruhøffer, Mogens; Simonsen, Ulf

    2011-01-01

    Background The present study investigated whether changes in gene expression in the right ventricle following pulmonary hypertension can be attributed to hypoxia or pressure loading. Methodology/Principal Findings To distinguish hypoxia from pressure-induced alterations, a group of rats underwent banding of the pulmonary trunk (PTB), sham operation, or the rats were exposed to normoxia or chronic, hypobaric hypoxia. Pressure measurements were performed and the right ventricle was analyzed by Affymetrix GeneChip, and selected genes were confirmed by quantitative PCR and immunoblotting. Right ventricular systolic blood pressure and right ventricle to body weight ratio were elevated in the PTB and the hypoxic rats. Expression of the same 172 genes was altered in the chronic hypoxic and PTB rats. Thus, gene expression of enzymes participating in fatty acid oxidation and the glycerol channel were downregulated. mRNA expression of aquaporin 7 was downregulated, but this was not the case for the protein expression. In contrast, monoamine oxidase A and tissue transglutaminase were upregulated both at gene and protein levels. 11 genes (e.g. insulin-like growth factor binding protein) were upregulated in the PTB experiment and downregulated in the hypoxic experiment, and 3 genes (e.g. c-kit tyrosine kinase) were downregulated in the PTB and upregulated in the hypoxic experiment. Conclusion/Significance Pressure load of the right ventricle induces a marked shift in the gene expression, which in case of the metabolic genes appears compensated at the protein level, while both expression of genes and proteins of importance for myocardial function and remodelling are altered by the increased pressure load of the right ventricle. These findings imply that treatment of pulmonary hypertension should also aim at reducing right ventricular pressure. PMID:21246034

    Abstract Chronic wounds – as defined by the World Union of Wound Healing Societies (WUWHS) – are a considerable worldwide health care expense and impair quality of life. In order for chronic wounds to heal, these wounds must be transformed to a more acute state to begin the healing process. Topical negative pressure (TNP) with reticulated open cell foam (ROCF) is known to promote healing in certain types of chronic wounds. However, little is known about changes at the cellular or molecular le...

Patients were given the Satisfaction with Information about Medicines Scale and the European Heart Failure Self-Care Behaviour Scale at their first visit and when the target dose was reached. Blood pressure, pulse and s-creatinine were measured at each visit.Results: Relationships were found between change in systolic (r = 0.224, p = 0.044 and diastolic (r = 0.361, p = 0.001 blood pressure and change in self-care scores and were also observed at baseline (r = 0.324, 0.398, p = 0.001, 0.000 and follow-up (r = 0.317, 0.253, p = 0.004, 0.022. Diastolic blood pressure correlated with the “potential problem of medication” score (r = −0.263, p = 0.007.Conclusion: Patients with a more advanced disease usually have a lower blood pressure. Hence, the relationship between blood pressure and self-care scores might indicate that patients are more motivated to adhere to prescriptions the more advanced the stage of their disease.Keywords: blood pressure, chronic heart failure, adherence, scales

  14. The effect of chronic reductions in the arterial partial pressure of oxygen on the radiation response of an experimental tumour

    International Nuclear Information System (INIS)

    A previous study by the same authors has reported the effect of acute reductions in the arterial partial pressure of oxygen (Pa02) on tumour response to radiation. The results have been extended in the present paper to investigate tumour response to radiation in animals in which the Pa02 is chronically reduced. The purpose of these experiments was to simulate the condition of cancer patients undergoing radiotherapy in the presence of chronically low Pa02 values as might be expected in patients with chronic respiratory disease. Mice bearing transplantable KHT sarcomas were kept in a 12% 02 environment prior to (10-16 days), during and following the radiation treatment of their tumours. During the period of low Pa02, (about 50 mm Hg) exposure, the mice were found to increase their haemoglobin (Hb) levels by approximately 50%. Because of this increase, the response, determined using a growth delay assay of the tumours irradiated at reduced Pa02 was found to be the same as that observed for tumours in mice breathing air throughout the experiment. In mice with reduced Pa02 levels maintained at normal Hb concentrations by periodic bleeding, tumour response was found to be similar to that of mice with acute Pa02 reductions. These results indicate that chronic Pa02 reductions in the absence of Hb compensation may have a detrimental effect on the success of a radiation treatment. (author)

  15. Organizational Sacralization and Discursive Use of Corporate Mission Statements

    2013-04-01

    Full Text Available The religious origin of organizational behavior is not easy to recognize, nor are the implications of the Christian heritage of concepts and ideas as applied to organizations. This paper seeks to remedy this by investigating the theological roots of the mission concept. Our central argument is that corporate mission statements are sometimes used as manipulative communicative tools which seek organizational legitimacy through the rhetorical inclusion of secularized Christian values. We find in Koselleck’s (1985 Conceptual History theoretical arguments by which to evaluate the bridge between theological and corporate concepts of mission. Then, we discuss mission as a theological concept, showing how it developed in modern societies and how its discursive use in business can be evaluated. With an analysis based on Habermas’ (1985 work, we conclude that, as a communicative tool, a corporate mission statement helps organizations manipulate meanings about their purposes and legitimacy in Christianity-based societies. This process reveals how the mission concept contributes to increase organizational sacralization and represents a powerful tool for improving a corporation´s social image and as a consequence may induce social consent.

    Full Text Available Chronic perineal pain limits patients in physical and sexual activities, leading to social and psychological distress. In most cases, this pain develops after surgery in the urogenital area or as a consequence of trauma. Neuromodulation is one of the options in chronic postsurgical perineal pain treatment. We present a case of refractory perineal pain after right sided surgical resection of a Bartholin’s cyst which was treated with third sacral nerve root/dorsal root ganglion stimulation using the transforaminal approach. We describe a new anchorless lead placement technique using a unique curved lead delivery sheath. We postulate that this new posterior foraminal technique of lead placement is simple, safe, and reversible and may lower the occurrence of lead related complications.

Mean VPI values: greater saphenous (GSV>smaller saphenous; GSV with isolated venous reflux (R at the leg>GSV at the thigh; additional R in perforators increases VPI in all the districts; superficial R increases VPI in PT. Relation between VPI/C of CEAP: P<0.05-0.0001; 81/83/96 (97.5% patients improved; 0 complained. R in GSV at the leg and in perforators increases VPI in deep veins. Few discrepancies VPI/CEAP can be expected. Standing VPI is highly predictive. The best choice of GES can be based on the VPI measurement.

  3. Computed tomography of the sacral plexus and sciatic nerve in the greater sciatic foramen

    International Nuclear Information System (INIS)

    The sacral plexus forms the sciatic nerve, which leaves the pelvis through the greater sciatic foramen. The anatomic boundaries of the greater sciatic foramen and the relation of the sacral plexus and sciatic nerve to the structures within are identified and described on axial computed tomography (CT). The piriform muscle, which passes through the center of the greater sciatic foramen, is a recognizable landmark that is extremely helpful in locating the sacral plexus and sciatic nerve on CT. The pelvic CT images of 25 patients studied for unrelated reasons and two patients studied for complaints related to the greater sciatic foramen were reviewed. CT was very useful in demonstrating the anatomy of this region and for the investigation of sciatic pain due to lesions outside the neural canal

    2011-03-01

    Sacral insufficiency fractures are an important and treatable cause of severe back pain. Despite publication of several case reports since its original description in 1982, awareness of these injuries remains inadequate in emergency medicine. Most patients are elderly women presenting with intractable lower back pain. Postmenopausal osteoporosis is the most significant risk factor. Marked sacral tenderness is common. Neurologic impairment is rarely detectable. Routine radiography of the spine and pelvis is usually inconclusive. Computed tomography remains the diagnostic modality of choice. Treatment is usually conservative.

    Full Text Available Graduated compression devices are considered the standard care for management of venous and lymphatic disorders. Recently compression devices exerting a pressure over the calf higher than over the ankle have been proved to be more effective than traditional graduated devices in increasing the impaired ejection fraction (EF from the lower leg in patients with venous disease. Aim of this work is presenting an overview of the new concept on progressive compression, its potential benefits and limits. In different series of tests, the EF from the lower leg was assessed in 70 patients with severe reflux in the great saphenous vein (GSV. EF was measured by strain gauge plethysmography, in baseline conditions and after applying graduated compression devices or the new inversely graduated or progressive compression (PC devices. The interface pressure was recorded, simultaneously with the EF, both in the gaiter area (B1 point and at the calf (C point in order to assess the compression pressure profile. EF, severely impaired in patients with GSV reflux, was increased by compression. So called PC devices (both PC elastic stocking and PC inelastic bandages were significantly more effective than graduated compression in increasing the ejection fraction. The higher the pressure on the calf the higher the EF improvement. Maintaining the same strong pressure over the calf by means of two progressive stockings and increasing the pressure only over the calf to restore a graduated compression didn’t improve the EF. To improve venous pumping function in the ambulant patient stronger compression of the calf is more effective than graduated compression. This can be explained by the higher amount of blood volume pooled in the calf veins.

    Background Sacral nerve injury is a common complication of pelvic or sacral fractures. As the sacral nerve courser within the sacrum and has a complex relationship with the surrounding tissues, different parts of the sacral plexus injury have similar clinical symptoms and signs. Since lack of specific imaging technique in the diagnosis of sacral nerve injury,especially on multi-segment, multi-site, how to determine the preoperative location and extent of the sacral nerve injury accurately becomes a concem of the general orthopaedic and images practitioners. This study was conducted to gain an insight into the overall anatomical features of the sacral nerve (SN) on the same slice in high resolution computed tomography (HRCT) reconstruction and to determine the value of this information for the clinical diagnosis of related diseases.Methods Fifty healthy volunteers and 30 patients (40 sides) with SN lesions confirmed by surgery were scanned using a 16-slice helical CT scanner (Light Speed, GE, USA). Among the patients, 6 with intervertebral disk hernia (6 sides), 8with spinal stenosis (12 sides), 11 with pelvic trauma (14 sides), 4 with pelvic malignancies (6 sides), and 1 with sacral vertebral tuberculosis (2 sides). The SN multiplanar reconstruction was performed using a UNIX-based SCD4.1workstation where the image was set on the same slice. All images were stored in the Digital Imaging and Communications in Medicine format. The display of nerves in different sections was analyzed using a five-graded scale with coordinate curves of each individual score. The overall anatomic features visible on the slice were analyzed and the abnormalities of the lesions were studied.Results The image of the same slice clearly revealed the shape, running direction, thickness, tension and adjacent anatomy of the S1-S4 nerves. The rank of display rates in different sections was: outward-rotated oblique sagittal >outward-rotated oblique coronal > oblique coronal plane > coronal

    Full Text Available The objective of this study is to compare the reduction of intraocular pressure (IOP after instillation of Travoprost compared with timolol in chronic primary angle-closure glaucoma. A prospective randomized, crossover study was conducted from April 2005 to July 2005 at Department of Ophthalmology, National Central General Hospital (RSCM Jakarta on subjects with chronic primary angle-closure glaucoma. Subjects were randomly divided into 2 groups: those taking Travoprost once daily and those taking timolol twice daily. Two weeks after treatment with the first drug, the second drug was substituted. Intraocular pressure was recorded before therapy, at day 1, day 7, and day 14. There was a wash out period of three weeks prior to initial treatment and after the cross over. Sixteen subjects (32 eyes met the inclusion criteria and were included in this study. The mean baseline IOP in the Travoprost group was 25.38 ± 3.01 mmHg, while in the timolol group it was 25.88 ± 2.55 mmHg (p=0.354. At day 7, the IOP were consecutively 16.75 + 1.92 mmHg and 21.25 + 3.09 mmHg (p=0.001 and at day 14 IOP were 13.94 + 2.02 mmHg and 19.25 + 2.18 mmHg (p=000. This showed that Travoprost decreased the IOP faster and greater than timolol. The mean baseline IOP was 25.38 ± 3.01 mmHg was decreased to 11.44 ± 1.90 mmHg with Travoprost. In the timolol group, the mean baseline IOP of 25.88 ± 2.55 mmHg was decreased to 6.63 ± 2.25 mmHg. Statistically, Travoprost significantly reduced the IOP faster and greater than timolol (p<0.05. Travoprost eye drops reduced the IOP faster and greater than timolol. (Med J Indones 2006; 15:242-5Keywords: chronic primary angle closure glaucoma, intraocular pressure, Travoprost, timolol.

    Full Text Available Abstract Introduction Hematuria has been described following bladder drainage in 2% to 16% of high-pressure chronic urinary retention treatments by decompression and is generally self-limiting. We describe a case of significant bilateral upper urinary tract hematuria following drainage of high-pressure chronic retention. To the best of our knowledge, the only similar case reported in the literature was in 1944. Case presentation An 82-year-old Caucasian man was referred to our department with nocturnal enuresis and a palpable bladder. He was catheterized, produced a residual volume of 2900mL, and ended up becoming oliguric. Following investigations, he had bilateral nephrostomies. He was discharged 18 days after presentation. Conclusions Clinicians should keep in mind the presentation discussed in this case report to be able to swiftly manage this extremely rare complication of decompression in patients with high-pressure chronic retention.

    Pulmonary hypertension (PH) is associated with aberrant vascular remodeling and right ventricular (RV) dysfunction that contribute to early mortality. Large animal models that recapitulate human PH are essential for mechanistic studies and evaluating novel therapies; however, these models are not readily accessible to the field owing to the need for advanced surgical techniques or hypoxia. In this study, we present a novel swine model that develops cardiopulmonary hemodynamics and structural changes characteristic of chronic PH. This percutaneous model was created in swine (n=6) by combining distal embolization of dextran beads with selective coiling of the lobar pulmonary arteries (2 procedures per lung over 4 weeks). As controls, findings from this model were compared with those from a standard weekly distal embolization model (n=6) and sham animals (n=4). Survival with the combined embolization model was 100%. At 8 weeks after the index procedure, combined embolization procedure animals had increased mean pulmonary artery pressure (mPA) and pulmonary vascular resistance (PVR) compared to the controls with no effect on left heart or systemic pressures. RV remodeling and RV dysfunction were also present with a decrease in the RV ejection fraction, increase in the myocardial performance index, impaired longitudinal function, as well as cardiomyocyte hypertrophy, and interstitial fibrosis, which were not present in the controls. Pulmonary vascular remodeling occurred in both embolization models, although only the combination embolization model had a decrease in pulmonary capacitance. Taken together, these cardiopulmonary hemodynamic and structural findings identify the novel combination embolization swine model as a valuable tool for future studies of chronic PH. PMID:25923775

    Full Text Available Identification of neural networks and pathways involved in activation and modulation of spinal central pattern generators (CPGs in the absence of the descending control from the brain is important for further understanding of neural control of movement and for developing innovative therapeutic approaches to improve the mobility of spinal cord injury patients. Activation of the hindlimb innervating segments by sacrocaudal afferent input and by specific application of neurochemicals to the sacral networks is feasible in the isolated spinal cord preparation of the newborn rat. Here we review our recent studies of sacral relay neurons with lumbar projections and evaluate their role in linking the sacral and thoracolumbar networks during different motor behaviors. Our major findings show that: 1 Heterogeneous groups of dorsal, intermediate and ventral sacral-neurons with ventral and lateral ascending funicular projections mediate the activation of the locomotor central pattern generators through sacral sensory input, and 2 Rhythmic excitation of lumbar flexor motoneurons, produced by bath application of alpha-1 adrenoceptor agonists to the sacral segments is mediated exclusively by ventral clusters of sacral-neurons with lumbar projections through the ventral funiculus.

    A pressure ulcer is an area of localized damage to the skin and underlying tissue caused by pressure or shear. Although these ulcers can occur anywhere on the body, they are often located in the ischial, trochanteric, sacral areas and. heel. These ulcers are primarily the products of a combination of pressure and decreased angiogenic response. Early intervention and comprehensive treatment should result in complete healing of ulcers. In this review, we tried to create a general perspective ab...

    Previous studies have demonstrated that left ventricular (LV) filling pressures can be estimated from transmitral Doppler recording in patients in sinus rhythm who have a broad spectrum of cardiac diseases. However, the correlation between pulmonary wedge pressure (PWP) and mitral Doppler profile has not yet been clearly defined in patients with atrial fibrillation, particularly in the presence of severe LV systolic dysfunction. The aim of this study was to evaluate the correlations between PWP and transmitral Doppler variables in patients with atrial fibrillation and chronic heart failure due to dilated cardiomyopathy. PWP and the mitral Doppler profile were simultaneously recorded in 35 consecutive heart failure patients (28 men, 7 women; mean age, 69 +/- 9 years) with severe LV dysfunction (mean ejection fraction 22% +/- 5%). Doppler measurements were averaged over 10 cardiac cycles. In addition, left atrial areas were derived from the apical 4-chamber view. Significant relations were observed between PWP and several parameters derived from the mitral flow: isovolumic relaxation time (r = -70), acceleration rate (r = 0.78), deceleration rate (r = 0.82), and deceleration time (r = -0.95). However, by stepwise multivariate analysis, deceleration time emerged as the sole independent predictor of PWP (r2 = 0.95, F = 590). The analysis led to the following equation: PWP = 51 - 0.26 (deceleration time). Our data suggest that mitral Doppler echocardiography is a useful tool for predicting PWP in heart failure patients with severe LV dysfunction even in the presence of atrial fibrillation.

    Full Text Available The current clinical practice has established guidelines to assess influences of severity of autonomic injury on the control of heart and blood pressure following spinal cord injury (SCI. However, the influences of SCI-induced autonomic impairment on microvascular dysfunction have not yet been established. Heart rate variability (HRV has been shown to be a potential tool for quantifying residual sympathovagal regulation of the cardiovascular system following SCI and may be used to assess the effect of autonomic injury on skin microvascular dysfunction. A total of 26 people were recruited into the study, including 12 people with SCI and 14 nondisabled controls. HRV and sacral skin intervals and sacral skin perfusion were continually recorded during 10 min upright and 10 min prone postures. The sympathovagal balance was defined as the ratio of the power of the low frequency to the high frequency of HRV. The results showed that postural changes of nondisabled people produced significant changes in the sympathovagal balance; lower sympathovagal balance was associated with higher skin perfusion (p < 0.05. People with SCI did not show a significant change of HRV and skin perfusion in response to postural changes. In this study, we have demonstrated that the sympathovagal balance assessed by HRV was associated with the skin vasoconstrictive response to postural changes.

    In this case report, we describe the use of the Draeger Apollo anesthesia machine to deliver bilevel positive airway pressure (BiPAP) to a patient with severe chronic obstructive pulmonary disease and a history of lung resection undergoing frontal craniotomy for the removal of a brain tumor under moderate to deep sedation. BiPAP in the perioperative period has been described for purposes of preoxygenation and postextubation recruitment. Although its utility as a mode of ventilation during moderate to deep sedation has been demonstrated, it has not come into widespread use. We describe the intraoperative use of pressure support mode on the anesthesia machine to deliver noninvasive positive pressure ventilation through a standard anesthesia mask. Given its ease of access and effectiveness, it is our belief that intraoperative BiPAP may reduce hypoxemia and/or hypercarbia in patients with chronic obstructive pulmonary disease and obstructive sleep apnea undergoing moderate to deep sedation.

    Abstract This study aims to evaluate the acute effects of an oscillating positive expiratory pressure device (flutter) on airways resistance in patients with chronic obstructive pulmonary disease (COPD). Randomized crossover study: 15 COPD outpatients from Asthma Lab–Royal Brompton Hospital underwent spirometry, impulse oscillometry (IOS) for respiratory resistance (R) and reactance (X), and fraction exhaled nitric oxide (FeNO) measures. Thirty minutes of flutter exercises: a “flutter-sham” procedure was used as a control, and airway responses after a short-acting bronchodilator were also assessed. Respiratory system resistance (R): in COPD patients an increase in X5insp (−0.21 to −0.33 kPa/L/s) and Fres (24.95 to 26.16 Hz) occurred immediately after flutter exercises without bronchodilator. Following 20 min of rest, a decrease in the R5, ΔR5, R20, X5, and Ax was observed, with R5, R20, and X5 values lower than baseline, with a moderate effect size; there were no changes in FeNO levels or spirometry. The use of flutter can decrease the respiratory system resistance and reactance and expiratory flow limitation in stable COPD patients with small amounts of secretions. PMID:26496331

    Full Text Available Dialysis is one of the used methods for treatment of Acute Renal Injury (ARI and Chronic Kidney Disease (CKD to replace the function of the kidneys when refers to blood depuration. Hemodialysis removes toxins accumulated in the body directly from the blood, being a useful alternative therapy for dogs and cats with CKD in advanced stages. Because of the difficulty on handling the patient feline, this procedure requires sedation. However, few studies have been conducted to assess the safety of anesthesia in dogs and cats with CKD undergoing dialysis. The present study aimed to evaluate two different protocols of chemical restraint in cats with CKD and the effect of these on systolic blood pressure (SBP and heart rate (HR, since the procedure of extracorporeal circulation leads the patient to a hypotensive frame. Twelve adult cats were used, with an average weight of 4 kg, CKD, underwent two anesthetic protocols: Group GP (n = 6 using propofol, and group GCM (n = 6 using ketamine-midazolam association for the implantation procedure of central venous catheter (CVC and hemodialysis. Cats in GP as well as the GCM group showed statistical difference in the change in SBP and HR only from baseline compared to the other time points evaluated. The two protocols maintained SBP and HR within physiological values.

    The occurrence of epidermoids within the spinal canal is uncommon. Most of the reported spinal epidermoids (SEs) have been described in the thoracic or lumbar regions. They occur either following trauma or in the setting of coexistent spinal dysraphism. The authors describe an unusual case of a 28-year-old lady who presented with long-standing back pain and urinary incontinence. Magnetic resonance imaging (MRI) of her spine demonstrated a sacral SE without any coexistent spinal dysraphism. The diagnosis of an epidermoid was confirmed by histopathological examination following laminectomy and excision. To the authors’ best knowledge, this is the third case of a sacral SE occurring in a non-dysraphic spine. The case is discussed in the light of a relevant literature review.

    Full Text Available Abstract Introduction We were able to treat a patient with acute exacerbation of chronic obstructive pulmonary disease who also suffered from sleep-disordered breathing by using the average volume-assured pressure support mode of a Respironics V60 Ventilator (Philips Respironics: United States. This allows a target tidal volume to be set based on automatic changes in inspiratory positive airway pressure. This removed the need to change the noninvasive positive pressure ventilation settings during the day and during sleep. The Respironics V60 Ventilator, in the average volume-assured pressure support mode, was attached to our patient and improved and stabilized his sleep-related hypoventilation by automatically adjusting force to within an acceptable range. Case presentation Our patient was a 74-year-old Japanese man who was hospitalized for treatment due to worsening of dyspnea and hypoxemia. He was diagnosed with acute exacerbation of chronic obstructive pulmonary disease and full-time biphasic positive airway pressure support ventilation was initiated. Our patient was temporarily provided with portable noninvasive positive pressure ventilation at night-time following an improvement in his condition, but his chronic obstructive pulmonary disease again worsened due to the recurrence of a respiratory infection. During the initial exacerbation, his tidal volume was significantly lower during sleep (378.9 ± 72.9mL than while awake (446.5 ± 63.3mL. A ventilator that allows ventilation to be maintained by automatically adjusting the inspiratory force to within an acceptable range was attached in average volume-assured pressure support mode, improving his sleep-related hypoventilation, which is often associated with the use of the Respironics V60 Ventilator. Polysomnography performed while our patient was on noninvasive positive pressure ventilation revealed obstructive sleep apnea syndrome (apnea-hypopnea index = 14, suggesting that his chronic

    International Nuclear Information System (INIS)

    Purpose: To evaluate the efficacy and safety of navigation-guided radiofrequency kyphoplasty for sacroplasty in patients with sacral insufficiency fractures. Methods: In this single-center retrospective observational study, four consecutive patients with sacral insufficiency fractures were treated with navigation-guided radiofrequency kyphoplasty for sacroplasty between April 2010 and May 2012. Symptom characteristics, pain duration and pain intensity were recorded for each patient. Cement extravasation was evaluated in thin-sliced and triplanar reconstructed CT scans of the sacrum. Results: Four female patients with painful sacral insufficiency fractures and extensive osteopenic areas significantly improved from an average pre-treatment VAS score of 8.3 ± 0.5 to 2.3 ± 1.0 (p < 0.001) on the first postoperative day and to 1.3 ± 1.9 (p < 0.004) at follow-up (mean, 20.1 weeks). Slight cement extravasations were observed without evidence of being symptomatic. No major complications or procedure-related morbidity were noted. Conclusion: From the limited experience in four patients, navigation-guided radiofrequency kyphoplasty appears to be a safe and effective treatment option for sacral insufficiency fractures even though asymptomatic cement extravasation was noted. The use of navigation based on intraoperative 3 D images simplifies the positioning of the navigated bone needles via the long axis approach. The radiofrequency kyphoplasty system provides the possibility to administer a sufficient amount of bone cement with a well-defined viscosity over the entire period of the procedure leading to high security and low cement extravasation. Sacroplasty provides rapid and enduring pain relief and facilitates prompt mobilization. (orig.)

  16. CT-guided screw fixation of vertical sacral fractures in local anaesthesia using a standard CT

    International Nuclear Information System (INIS)

    To evaluate time efficiency, radiation dose, precision and complications of percutaneous iliosacral screw placement under CT-guidance in local anaesthesia. Retrospective analysis of 143 interventions in 135 patients during a period of 42 months. Implant failures could be evaluated in 85/182 screws and bony healing or refracturing in 46/182 screws. A total of 182 iliosacral screw placements in 179 vertical sacral fractures (105 unilateral, 37 bilateral) took place in 135 patients. 166/179 of the sacral fractures were detected in Denis zone 1, 10 in Denis zone 2 and 3 in Denis zone 3. No screw misplacements including the simultaneous bilateral procedures were noted. The average time for a unilateral screw placement was 23 minutes (range: 14-52 minutes) and 35 minutes (range: 21-60 minutes) for simultaneous bilateral screwing. The dose length product was 365 mGy x cm (range: 162-1014 mGy x cm) for the unilateral and 470 mGy x cm (range: 270-1271 mGy x cm) for the bilateral procedure. 1 gluteal bleeding occurred as the only acute minor complication (0.7%). Fracture healing was verified with follow-up CTs in 42/46 sacral fractures after screw placement. Backing out occurred in 12/85 screws between 6 and 69 days after intervention. In 8 patients contralateral stress fractures were detected after unilateral screw placement between day 10 and 127 (average: 48 days). CT-guided iliosacral screw placement in sacral fractures is a safe tool providing a very high precision. The radiation dose is in the order of a diagnostic CT of the pelvis for both unilateral and bilateral screws. Contralateral stress fractures in unilateral screw placements have to be considered during the first weeks after intervention.

    Because physical examination typically demonstrates normal findings in cases of low-back pain, diaglosis of the cause can be challenging. Frequent magnetic resonance imaging studies of the lumbosacral spine can typically lead to discovery of benign diseases and thus misinterpretation of these images. The authors report an unusual case in which a functional ovarian cyst was incidentally associated with a perineural cyst and mimicked a lateral sacral meningocele. In light of this, the authors recommend repeated examinations to avoid mistakes. PMID:15658130

    Full Text Available Correlation between sacral ratio and bowel function as well as fecal continence has been well documented in patients with anorectal malformations (ARMs. One hundred and twenty children with ARMs were investigated in this study. Sacral ratio (SR was measured from pelvic X-rays of patients. Among these, 52 patients (43% had no pelvic X-ray and were excluded from this study. SR was measured by drawing three horizontal lines, through iliac crests (A, tip of coccyx (B and inferior point of sacroiliac joints (C. The SR was determined by dividing the distance between lines B and C to the distance between lines A and B. In the normal and well developed children, the average ratio is ≥0.74. The SR was higher than 0.70 in 12 (17.7% children and less than 0.69 in 56 children (82.3%. Among children with ARMs and abnormal SR, 38 cases (68% had SR of 0.50-0.69; 12 cases (21.5%had SR of 0.40-0.49 and 6 cases (10.5% had SR of 0-0.39. In children with ARMs and normal SR, the fecal incontinence was observed in 2 cases (16%. In contrast, 16 cases (29% with ARMs and abnormal SR had functional disturbance, either fecal incontinence or soiling (P < 0.12. When the patients had an absent sacrum, they had zero possibility for bowel control and frequently had major urinary problems. The sacral feature and SR appear to have a direct influence on the final functional outcome in ARMs. The abnormal SR < 0.7 correlates with poor bowel function. In patients with ARMs, sacral segment and SR are important factors in post operative bowel function disturbance.

    Full Text Available Background: Acute exacerbations of chronic obstructive pulmonary disease (AeCOPD are important causes of morbidity and mortality. In this study, we analyzed procalcitonin (PCT levels in AeCOPD and stable period of COPD in order to evaluate usage of PCT in the prediction of the severity of AeCOPD, and its value on the planing of noninvasive positive pressure ventilation (NPPV. Materials and Methods: In this cross sectional study (2009-2010 118 COPD patients were enrolled, 68 of them (58% were in acute exacerbations (case group. The others had stabile COPD and they were defined as control group. Results: In case group the mean levels of PCT (0.19 ± 0.02 C-Reactive Protein (44.7 ± 5.92, erythrocyte sedimentation rate (28.4 ± 2.65, white blood cell (9.4 ± 0.43 and %neutrophils (69.9 ± 1.22 were significantly higher than controls (P = 0.0001. There was no difference between PCT levels based on stages of COPD. There were significiant differences in mean PCT levels according to type and severity of AeCOPD. Mean PCT level in hospitalized patients receiving NPPV was 0.36 ng/ml, while it was 0.15 ng/ml for those treated without NPPV (P = 0.0001. PCT cut-off value for NPPV indication was determined to be 0.10 ng/ml. Conclusions: PCT levels were found to be higher in AeCOPD patients than in stable COPD patients, as expected. Also mean PCT levels increased especially in cases with severe AeCOPD and those receiving NPPV among them. In the present study, we determined a cut off value of PCT as 0.10 ng/ml as a predictor of necessity of NPPV in AeCOPD.

  4. Miso (Japanese soybean paste) soup attenuates salt-induced sympathoexcitation and left ventricular dysfunction in mice with chronic pressure overload.

    The hypothalamic mineralocorticoid receptor (MR)-angiotensin II type 1 receptor (AT1R) pathway is activated in mice with chronic pressure overload (CPO). When this activation is combined with high salt intake, it leads to sympathoexcitation, hypertension, and left ventricular (LV) dysfunction. Salt intake is thus an important factor that contributes to heart failure. Miso, a traditional Japanese food made from fermented soybeans, rice, wheat, or oats, can attenuate salt-induced hypertension in rats. However, its effects on CPO mice with salt-induced sympathoexcitation and LV dysfunction are unclear. Here, we investigated whether miso has protective effects in these mice. We also evaluated mechanisms associated with the hypothalamic MR-AT1R pathway. Aortic banding was used to produce CPO, and a sham operation was performed for controls. At 2 weeks after surgery, the mice were given water containing high NaCl levels (0.5%, 1.0%, and 1.5%) for 4 weeks. The high salt loading in CPO mice increased excretion of urinary norepinephrine (uNE), a marker of sympathetic activity, in an NaCl concentration-dependent manner; however, this was not observed in Sham mice. Subsequently, CPO mice were administered 1.0% NaCl water (CPO-H) or miso soup (1.0% NaCl equivalent, CPO-miso). The expression of hypothalamic MR, serum glucocorticoid-induced kinase-1 (SGK-1), and AT1R was higher in the CPO-H mice than in the Sham mice; however, the expression of these proteins was attenuated in the CPO-miso group. Although the CPO-miso mice had higher sodium intake, salt-induced sympathoexcitation was lower in these mice than in the CPO-H group. Our findings indicate that regular intake of miso soup attenuates salt-induced sympathoexcitation in CPO mice via inhibition of the hypothalamic MR-AT1R pathway. PMID:24908908

    Full Text Available The importance of physical exercise for patients with systemic hypertension is well established in the literature. However, ballroom dance has been little investigated in this context. The objective of this study was to determine the chronic effect of ballroom dance on blood pressure in medicated hypertensives. The sample was the number of blood pressure measurements obtained during the patients’ participation in the dance program. Thus, 92 blood pressure measurements were taken and divided into four groups: 1 pre-session systolic blood pressure, 2 post-session systolic blood pressure, 3 pre-session diastolic blood pressure, 4 post-session diastolic blood pressure. We used a mercury sphygmomanometer and stethoscope. As measuring protocol, we considered the Brazilian Guidelines. Blood pressure was measured before and after each ballroom dance session. The mean age of the 23 medicated hypertensive patients studied was 62.5 ± 7 years and 34.8% of them were male. Forty sessions were held three times a week, lasting one hour/session. The mean pre-session systolic blood pressure was 131,8 ± 17mmHg and 117,8±13mmHg after the session, with statistically significant difference (p <0.001; in diastolic blood pressure values were 70,7±6mmHg and 67,7±9mmHg (p <0.075. We conclude that ballroom dance can contribute to a better control of blood pressure in medicated hypertensive patients, which may be considered as a cardiac rehabilitation exercise.

    Objective To report a case of cryptococcus neoformans osteomyelitis of the sacral vertebrae and to analyze the cause of misdiagnosis. Methods The clinical data of a patient with cryptococcus neoformans osteomyelitis of the sacral vertebrae who was adopted in 2012 were retrospectively analyzed. Results Intermittent pain in the sacrum occurred to the patient without any obvious precipitating factors, which became worse at night. And meanwhile, the patient had low-grade fever. Whole body bone scan and single photon emission computed tomography ( SPECT )/CT showed abnormally active metabolism in the sacrum and bony defects and changes in the right margin. Therefore, bone tumors were considered. Sacral metastases was conifrmed using CT-guided needle aspiration biopsy. Debridement was performed after multidisciplinary consultation. The intraoperative frozen pathology presented fungal infections. The postoperative routine pathological examination showed pyogenic and inlfammatory granulomas and there were fungal spores in the histocytes. At last, sacral cryptococcus infections was diagnosed. Conclusions The partial performance of cryptococcus neoformans osteomyelitis of the sacral vertebrae is similar to that of malignant tumors of the sacral vertebrae. So clinical doctors should raise the awareness of the disease. It is necessary to ifrst rule out the possibility of cryptococcus neoformans osteomyelitis of the sacral vertebrae before making the diagnosis of malignant tumors of the sacral vertebrae.

    Posterior lumbopelvic fixation with iliac screws is the most commonly used method for unstable spinopelvic injuries. It has certain limitations including inability to use distraction along the spinopelvic rod as an indirect reduction maneuver, need for complex 3-dimensional rod contouring and complications such as hardware prominence and soft tissue coverage. In the present case report,we described a surgical technique of lumbopelvic fixation with sacral alar screws for traumatic spinopelvic instability resulted from a unilateral Denis-Ⅲ comminuted sacral fracture and the L5 burst fracture. On the opposite side of the sacral fracture, caudal screws were implanted into the pedicle of the S1, whereas on the side of sacral fracture, two sacral alar screws were placed parallel to the superior sacral endplate as well as the plane of sacroiliac joint. In addition,horizontal stabilization was conducted with cross-link connections to maintain the longitudinal traction. For sacral fracture associated with traumatic spinopelvic instability,this modified lumbopelvic fixation technique using sacral alar screws makes longitudinal reduction easier, requires less rod contouring, and reduces hardware prominence without compromising the stability.

    Falls are unpredictable accidents, and the resulting injuries can be serious in the elderly, particularly those with chronic diseases. Regular exercise is recommended to prevent and treat hypertension and other chronic diseases by reducing clinical blood pressure. The "complexity index" (CI), based on multiscale entropy (MSE) algorithm, has been applied in recent studies to show a person's adaptability to intrinsic and external perturbations and widely used measure of postural sway or stability. The multivariate multiscale entropy (MMSE) was advanced algorithm used to calculate the complexity index (CI) values of the center of pressure (COP) data. In this study, we applied the MSE & MMSE to analyze gait function of 24 elderly, chronically ill patients (44% female; 56% male; mean age, 67.56 ± 10.70 years) with either cardiovascular disease, diabetes mellitus, or osteoporosis. After a 12-week training program, postural stability measurements showed significant improvements. Our results showed beneficial effects of resistance training, which can be used to improve postural stability in the elderly and indicated that MMSE algorithms to calculate CI of the COP data were superior to the multiscale entropy (MSE) algorithm to identify the sense of balance in the elderly.

  14. MR imaging features of giant pre-sacral schwannomas: a report of four cases

    International Nuclear Information System (INIS)

    Benign giant sacral schwannoma is an uncommon cause of destruction of the sacrum. This report details four cases of a variant of this condition called giant presacral schwannoma (GPSS). On MR imaging the features are of a large, well-defined presacral soft tissue mass, arising just to one side of the midline with minor involvement of the bone. The typical MR features of a benign peripheral nerve sheath tumour are not seen. The tumours appear heterogeneous due to long-standing degeneration. Biopsy is advocated as the appearances of GPSS can be similar to a malignant peripheral nerve sheath tumour (malignant schwannoma). (orig.)

    Our aim was to assess the clinical outcome of patients who were subjected to long-axis sacroplasty for the treatment of sacral insufficiency fractures. Nineteen patients with unilateral (n = 3) or bilateral (n = 16) sacral fractures were involved. Under local anaesthesia, each patient was subjected to CT-guided sacroplasty using the long-axis approach through a single entry point. An average of 6 ml of polymethylmethacrylate (PMMA) was delivered along the path of each sacral fracture. For each individual patient, the Visual Analogue pain Scale (VAS) before sacroplasty and at 1, 4, 24 and 48 weeks after the procedure was obtained. Furthermore, the use of analgesics (narcotic/non-narcotic) along with the evolution of post-interventional patient mobility before and after sacroplasty was also recorded. The mean pre-procedure VAS was 8 {+-} 1.9 (range, 2 to 10). This rapidly and significantly (P < 0.001) declined in the first week after the procedure (mean 4 {+-} 1.4; range, 1 to 7) followed by a gradual and significant (P < 0.001) decrease along the rest of the follow-up period at 4 weeks (mean 3 {+-} 1.1; range, 1 to 5), 24 weeks (mean 2.2 {+-} 1.1; range, 1 to 5) and 48 weeks (mean 1.6 {+-} 1.1; range, 1 to 5). Eleven (58%) patients were under narcotic analgesia before sacroplasty, whereas 8 (42%) patients were using non-narcotics. Corresponding values after the procedure were 2/19 (10%; narcotic, one of them was on reserve) and 10/19 (53%; non-narcotic). The remaining 7 (37%) patients did not address post-procedure analgesic use. The evolution of post-interventional mobility was favourable in the study group as they revealed a significant improvement in their mobility point scale (P < 0.001). Long-axis percutaneous sacroplasty is a suitable, minimally invasive treatment option for patients who present with sacral insufficiency fractures. More studies with larger patient numbers are needed to explore any unrecognised limitations of this therapeutic approach. (orig.)

  16. Intrasubstance Schwannoma of Posterior Tibial Nerve Presenting as Lumbo-Sacral Radiculopathy

    Introduction: Peripheral nerve tumours are rarely acknowledged as a cause of radiating pain in lower limbs and suspicion is almost always pointed towards lumbo-sacral causes. Schwannomas are tumours of peripheral nerve sheaths occurring anywhere along the peripheral nervous system. Often it can produce symptoms, which can be misleading in cases where obvious swelling is not present. The diagnosis may therefore be delayed by several years of emergence of symptoms. Very few such cases have been reported previously and none of them had an intrasubstance location of the tumour as in our case. Case Report: We present a case of a middle aged female patient presenting with radiating pain in left lower limb, which was diagnosed and treated as lumbo-sacral radiculopathy for five years before an obvious swelling appeared, which on further investigations led to diagnosis of schwannoma of tibial nerve. Intraoperatively, the schwannoma was found to be intrasubstance in location which has never been reported in the past literatures making its excision, without damaging the conducting elements, a challenge. Conclusion: The possibility of peripheral nerve tumour should always be kept in mind while dealing with long standing cases diagnosed as radiculopathy and which do not get better with treatment on similar lines. A thorough clinical examination of the entire limb including Tinel’s sign can clinch the diagnosis earlier in cases where obvious swelling is not present. Even unusual presentations, as in our case, can be dealt surgically with good results. PMID:27299039

    Full Text Available Sacral agenesis (SA is a rare condition consisting of the imperfect development of any part of the sacrum. This paper describes two cases of the rare cooccurrence of ipsilateral SA and developmental dysplasia of the hip (DDH and analyzes possible contributory factors for SA and DDH. Each of a 16-year-old female and 13-year-old female visited our hospital for left hip pain and limping. The findings of physical examinations showed a lower limb length discrepancy (left side in both cases, as well as left hip pain without limitations of the range of motion or neurological deficits. Initial radiographs demonstrated left subluxation of the left hip with associated acetabular dysplasia and partial left sacral agenesis. MRI revealed a tethering cord with a fatty filum terminale, and periacetabular osteotomy combined with allogeneic bone grafting was performed. After the surgery, the patients experienced no further pain, with no leg length discrepancy and were able to walk without a limp, being neurologically normal with a normal left hip range of motion. The cooccurrence of SA and DDH suggests a plausible hypothesis to explain the embryogenic relationship between malformation of the sacrum and hip.

    Caudal epidural steroid injection is a very common intervention in treatment of low back pain and sciatica symptoms. Although extensively used, it is not devoid of complications. A few reports of chemical and infective arachnoiditis exist following lumbar epidural anaesthesia, but none following a caudal epidural steroid injection.We report a case of arachnoiditis following caudal epidural steroid injections for lumbar radiculopathy. The patient presented with contralateral sciatica, worsening low back pain and urinary retention few days following the injection, followed by worsening motor functions in L4/L5/S1 myotomes with resultant dense foot drop. Gadolinium-enhanced magnetic resonance imaging suggested infective arachnoiditis with diffuse enhancement and clumping of the nerve roots within the lumbar and sacral thecal sac. As the number of injections in the management of back pain and lumbo-sacral radicular pain is increasing annually, it is imperative to have a thorough understanding of this potentially dangerous complication and educate the patients appropriately.

    2014-01-01

    Full Text Available Sacral giant cell tumors are rare neoplasms, histologically benign but potentially very aggressive due to the difficulty in achieving a complete resection, their high recurrence rate, and metastization capability. Although many treatment options have been proposed, en bloc excision with tumor-free margins seems to be the most effective, being associated with long term tumor control, improved outcome, and potential cure. An exemplifying case of a 29-year-old female with progressive complaints of pain and paresthesias in the sacral and perianal regions, constipation, and weight loss for 6 months is presented. The surgical technique for en bloc excision of a large sacral giant cell tumor through a modified Kraske procedure with mid-sacrectomy and coccygectomy is described. Complete resection with wide tumor-free margins was achieved. At 5 years of follow-up the patient is neurologically intact, without evidence of local recurrence on imaging studies. A multidisciplinary surgical procedure is mandatory to completely remove sacral tumors. In the particular case of giant cell tumors, it allows minimizing local recurrence preserving neurovascular function, through a single dorsal and definitive approach.

  20. Hypointensity on postcontrast MR imaging from compression of the sacral promontory in enlarged uterus with huge leiomyoma and adenomyosis

    International Nuclear Information System (INIS)

    In patients with huge leiomyoma and with adenomyosis of the uterus, a peculiar area of hypointensity was occasionally observed on postcontrast magnetic resonance (MR) imaging in the dorsal portion of the enlarged uterus near the sacral promontory. We describe the imaging characteristics of these MR findings and correlate them with histopathological findings to examine whether the areas represent specific pathological changes. Ten patients with huge leiomyomas and two with huge adenomyotic lesions whose imaging revealed the hypointensity were enrolled. All had enlarged uteri that extended beyond the sacral promontory. MR findings of the hypointense areas were evaluated and correlated with histopathological findings in 5 patients with leiomyoma and two with adenomyosis who had hysterectomy. The ten patients with leiomyoma showed flare-shaped hypointensity arising from the dorsal surface of the uterine body that extended deep into the tumor. The base of the hypointense areas was narrow in 5 patients with intramural leiomyoma and broad in five with subserosal leiomyoma. Two patients with adenomyosis showed nodular-shaped areas of hypointensity in front of the sacral promontory. Precontrast T1- and T2-weighted MR images showed no signal abnormalities in the portions corresponding to the hypointensity in any of the 12 patients. Pathological examinations showed no specific findings in the portions corresponding to the hypointensity in the 7 patients who had hysterectomy. The areas of hypointensity may represent functional changes, such as decreased localized blood flow caused by compression of the sacral promontory. (author)

    Full Text Available This is a paper reviewing the National Health Service (NHS agenda in relation to the use of Negative Pressure Wound Therapy (NPWT in chronic wound management and assesses the evidence behind it, its cost effectiveness and the outcome it has on patients’ satisfaction and life style. Multiple studies over the last 10 years looking at clinical efficacy of NPWT with its cost effectiveness and the implementation of this service in the UK were reviewed. NPWT has showed a reasonable body of evidence to support its usage in chronic wounds with potential positive outcomes on finance and patients’ satisfaction. However, the NHS system shows significant variations in the availability and implementation of this useful tool, depending on care providers and resources availabilities. The paper concluded that the NPWT can be a useful source of cutting down costs of chronic wound managements and saving money by its effect on expediting wound healing, which can address a part of the financial crises facing the NHS, however, has to be considered according to specific case needs. There should also be a national standard for the availability and indication of this tool to assure equal opportunities for different patients in different areas in the country.

  4. Chronic Blockade of the Androgen Receptor Abolishes Age-Dependent Increases in Blood Pressure in Female Growth-Restricted Rats.

    Intrauterine growth restriction induced via placental insufficiency programs a significant increase in blood pressure at 12 months of age in female growth-restricted rats that is associated with early cessation of estrous cyclicity, indicative of premature reproductive senescence. In addition, female growth-restricted rats at 12 months of age exhibit a significant increase in circulating testosterone with no change in circulating estradiol. Testosterone is positively associated with blood pressure after menopause in women. Thus, we tested the hypothesis that androgen receptor blockade would abolish the significant increase in blood pressure that develops with age in female growth-restricted rats. Mean arterial pressure was measured in animals pretreated with and without the androgen receptor antagonist, flutamide (8 mg/kg/day, SC for 2 weeks). Flutamide abolished the significant increase in blood pressure in growth-restricted rats relative to control at 12 months of age. To examine the mechanism(s) by which androgens contribute to increased blood pressure in growth-restricted rats, blood pressure was assessed in rats untreated or treated with enalapril (250 mg/L for 2 weeks). Enalapril eliminated the increase in blood pressure in growth-restricted relative to vehicle- and flutamide-treated controls. Furthermore, the increase in medullary angiotensin type 1 receptor mRNA expression was abolished in flutamide-treated growth-restricted relative to untreated counterparts and controls; cortical angiotensin-converting enzyme mRNA expression was reduced in flutamide-treated growth-restricted versus untreated counterparts. Thus, these data indicate that androgens, via activation of the renin-angiotensin system, are important mediators of increased blood pressure that develops by 12 months of age in female growth-restricted rats.

    Full Text Available Abstract OBJECTIVE To evaluate the costs of a topical treatment of pressure ulcer (PU patients in a hospital unit for treatment of chronic patients in 2014. METHOD This is an activity-based costing study. This method encompasses the identification, measurement and pricing of physical and human resources consumed for dressings. RESULTS Procedure costs varied between BRL 16.41 and BRL 260.18. For PUs of the same category, of near areas and with the same type of barrier/adjuvant, the cost varied between 3.5% and 614.6%. For most dressings, the cost increased proportionally to the increase of the area and to the development of PU category. The primary barrier accounted for a high percentage of costs among all items required to the application of dressings (human and material resources. Dressings applied in sacral PUs had longer application times. CONCLUSION This study allowed us to understand the costs involved in the treatment of PUs, and it may support decision-makers and other cost-effectiveness studies.

    Anterior sacral meningoceles (ASMs) are rare defects in the sacrum with thecal sac herniations and symptoms that commonly include constipation, dysmenorrhea, and urinary disturbances. An ASM causing hydronephrosis and acute renal failure from compression of the lower portion of the urinary tract is a rare clinical entity. Only one other case has been reported. The authors present the case of a 37-year-old man admitted for obstructive renal failure and hydronephrosis due to a giant ASM that measured 25 × 12 × 18 cm and compressed the ureters and bladder. The ASM was successfully treated via an anterior transabdominal approach in which the authors used a novel technique for watertight closure of the meningocele pedicle with an endoscopic cutting stapler. The authors review the literature and discuss the surgical options for the treatment of ASMs, specifically the management of ASMs in the context of obstructive renal failure and hydronephrosis.

  13. Sacral meningeal arteriovenous fistula fed by branches of the hypogastric arteries and drained through medullary veins

    International Nuclear Information System (INIS)

    The authors report a new case of intra-spinal extra-medullary meningeal arteriovenous fistula draining through medullary veins. Discovered in a 33-year-old black man suffering from a cauda equina syndrome, this malformation suspected in myelography was confirmed by a selective angiographic procedure of both internal iliac arteries. This investigation specified the sacral site of the fistula as well as its feeding arteries from several branches of the left and right internal iliac arteries and its posterior and intra-meningeal venous medullary drainage. An embolization procedure followed by a surgical approach and a second embolization session brought a fair improvement to this young patient who could walk again. The acquired traumatic origin of the fistula is discussed for this patient who had been previously operated at his L5-S1 level. (orig.)

    Full Text Available Lumbosacral transitional vertebra (LSTV are congenital anomalies of the lumbosacral spine causing sacralisation or lumbarisation. Sacralisation has been defined as an abnormality where one of the transverse processes of L5 vertebra may articulate or fuse with the sacrum. The sacralisation has been studied for almost a century for its association with low back pain as “Bertolotti Syndrome”, but there are studies for and against its association. Castellvi in 1984 had propounded a radiographical classification identifying sacralisation in four sub types. Out of this, the Type IIA, is the least prevalent wherein there is a unilateral articulation of the L5 transverse process with the sacral ala. Inspite of the controversy, there is a high association of low back pain with disc degeneration, nerve root compression and degenerative facet joints observed with this condition. It is a widely researched vertebral anomaly for its anatomical, developmental and clinical ramifications.

    Sacrectomy and ilio-lumbar reconstruction is an uncommonly performed complex surgical procedure for the treatment of sacral neoplasia. There are many challenges in the post-operative period including the potential for tumor recurrence, infection, and construct failure. We present our experience of this patient cohort and describe the complications and imaging appearances that can be encountered during the follow-up period. Retrospective review of our Orthopaedic Oncology database was undertaken which has been collected over a 30-year period to identify patients that had undergone sacrectomy and ilio-lumbar reconstruction. Pre and post-operative imaging including radiographs, CT, and MRI was reviewed. These were viewed by two experienced musculoskeletal radiologists with consensus opinion if there was disagreement over the imaging findings. Data regarding patient demographics, tumor type, and dimensions was collected. Serial review of radiographs, CT, and MRI was performed to assess implant position and integrity, strut graft position and union, and for the presence of recurrence within the surgical bed. Five male and two female patients (mean age 36 years, age range 15-54 years) were treated with this procedure. Histological diagnoses included chordoma, chondrosarcoma, osteosarcoma, and spindle cell sarcoma. Mean maximal tumor size on pre-operative imaging was 10.7 cm (range, 6-16 cm). Post-operative follow-up ranged from 10-46 months. A total of 76 imaging studies were reviewed. Commonly identified complications included vertical rod and cross-connector fracture and screw loosening. Fibula strut graft non-union and fracture was also evident on imaging review. Two patients demonstrated disease recurrence during the follow-up period. This study demonstrates the spectrum and frequency of complications that can occur following sacrectomy and ilio-lumbar reconstruction for sacral neoplasia. (orig.)

  16. Clinical Outcome of Sacral Chordoma With Carbon Ion Radiotherapy Compared With Surgery

    International Nuclear Information System (INIS)

    Purpose: To evaluate the efficacy, post-treatment function, toxicity, and complications of carbon ion radiotherapy (RT) for sacral chordoma compared with surgery. Methods and Materials: The records of 17 primary sacral chordoma patients treated since 1990 with surgery (n = 10) or carbon ion RT (n = 7) were retrospectively analyzed for disease-specific survival, local recurrence-free survival, complications, and functional outcome. The applied carbon ion dose ranged from 54.0 Gray equivalent (GyE) to 73.6 GyE (median 70.4). Results: The mean age at treatment was 55 years for the surgery group and 65 years for the carbon ion RT group. The median duration of follow-up was 76 months for the surgery group and 49 months for the carbon ion RT group. The local recurrence-free survival rate at 5 years was 62.5% for the surgery and 100% for the carbon ion RT group, and the disease-specific survival rate at 5 years was 85.7% and 53.3%, respectively. Urinary-anorectal function worsened in 6 patients (60%) in the surgery group, but it was unchanged in all the patients who had undergone carbon ion RT. Postoperative wound complications requiring reoperation occurred in 3 patients (30%) after surgery and in 1 patient (14%) after carbon ion RT. The functional outcome evaluated using the Musculoskeletal Tumor Society scoring system revealed 55% in the surgery group and 75% in the carbon ion RT group. Of the six factors in this scoring system, the carbon ion RT group had significantly greater scores in emotional acceptance than did the surgery group. Conclusion: Carbon ion RT results in a high local control rate and preservation of urinary-anorectal function compared with surgery.

Methods: Two groups of female subjects – patients with chronic WAD (n = 28 and healthy controls (CON; n = 29 – were investigated. Quantitative sensory testing (QST for thermal thresholds and algometry for PPT at four sites in the body (over the trapezius and tibialis anterior bilaterally were determined. Habitual pain intensities, psychological strain, disability, and health aspects were registered using a questionnaire.Results: A cluster analysis based on PPT, CPT, and HPT identified two subgroups of chronic WAD: one sensitive subgroup (s-WAD; n = 21, and one less sensitive subgroup (ls-WAD; n = 6. S-WAD displayed widespread hyperalgesia, whereas ls-WAD had localized hyperalgesia in the neck area, with tendencies to supernormal values in remote areas of the body. Generally, s-WAD had a significantly worse situation than the CON with respect to symptomatology, disability, and health aspects. The ls-WAD group was intermediary between s-WAD and CON in these aspects.Conclusion: Different explanations, eg, severity of the pain condition per se, etiological factors, and pre-trauma differences in pain sensitivity, may exist for the differences in pain thresholds between the two subgroups. Future research should investigate the role of pain thresholds in the chronic

  19. Myocardial fatty acid imaging with 123I-BMIPP in patients with chronic right ventricular pressure overload. Clinical significance of reduced uptake in interventricular septum

    International Nuclear Information System (INIS)

    Regionally reduced 123I-beta-methyliodophenyl pentadecanoic acid (123I-BMIPP) uptake in the interventricular septum (SEP) is observed in some patients with chronic right ventricular (RV) pressure overload. We studied the significance of this finding by comparing it with mean pulmonary arterial pressure (mPAP). 123I-BMIPP SPECT imaging was carried out in 21 patients with pulmonary hypertension (PH; 51+-14 years; 11 men and 10 women; 7 with primary pulmonary hypertension, 11 with pulmonary thromboembolism, and 3 with atrial septal defect). mPAP ranged from 25 to 81 mmHg (49±16 mmHg). Using a midventricular horizontal long-axis plane, regional BMIPP distributions in the RV free wall and SEP were estimated by referring to those in the LV free wall. Count ratios of the RV free wall and SEP to the LV free wall (RV/LV, SEP/LV) were determined by ROI analysis. RV/LV showed a linear correlation with mPAP (r=0.42). However, SEP/LV was inversely correlated with mPAP (r=-0.49). When SEP/RV was compared among three regions of SEP in each patient, basal SEP/RV was most sensitively decreased in response to increased mPAP (r=-0.70). These results suggest that the assessment of septal tracer uptake in 123I-BMIPP SPECT imaging is useful for evaluating the severity of RV pressure overload in patients with PH. (author)

    Hereditary neuropathy with liability to pressure palsies is an inherited disease associated with the loss of a copy of the PMP22 gene. The condition leads to mononeuropathy due to compression and easy strangulation during daily life activities, resulting in sudden muscle weakness and sensory disturbance, and displaying symptoms similar to cerebrovascular diseases. We report the case of an 80-year-old man with left paralysis due to chronic cerebral infarction. His medical history indicated remarkable recovery from about 4 months after the onset of left hemiplegia with predominant involvement of the fingers. Despite subsequent recurrent monoplegia of the upper or lower limbs, brain magnetic resonance imaging consistently revealed only previous cerebral infarction in the right corona radiata without new lesions. Medical examination showed reduced deep tendon reflexes in his extremities on both the healthy and hemiplegic sides. Nerve conduction studies showed delayed conduction at the bilateral carpal and cubital tunnels and near the right caput fibulae. Genetic analysis revealed loss of a copy of the PMP22 gene. Thus, he was diagnosed with a cerebral infarction complicated by hereditary neuropathy with liability to pressure palsies. Stroke patients develop sudden muscle weakness and sensory disturbance. However, if such patients have no hyperactive deep tendon reflexes and show atypical recovery of paralysis that does not correspond to findings of imaging modalities, nerve conduction studies and genetic analysis may be necessary, considering the complication of hereditary neuropathy with liability to pressure palsies.

    patient is characterized as carrying the Currarino Syndrome. Discussion: The syndrome is characterized by the malformation of the anorectal, sacral abnormalties and retrorectal mass. It has connection with a gene mutation of the HLXB9. The Tailgut Cyst is an embryological remnant of the hindgut, more common in young adult women (75-90%. The tailgut cyst related to the Currarino Syndrome is an uncommom lesion. Most patients are asymptomatic, however, they may present anorectal, perineo and sacrum symptoms. Imaging exams are useful for diagnostic definition and surgery programming. The complete surgery excision is recommended due to the risk of reestablishment, malignant degeneration and chronic infection, even in asymptomatic patients. The prognosis is uncertain.

  2. SU-E-J-125: A Novel IMRT Planning Technique to Spare Sacral Bone Marrow in Pelvic Cancer Patients

    International Nuclear Information System (INIS)

    Purpose: Develop an IMRT planning technique that can preferentially spare sacral bone marrow for pelvic cancer patients. Methods: Six pelvic cancer patients (two each with anal, cervical, and rectal cancer) were enrolled in an IRB approved protocol to obtain FLT PET images at simulation, during, and post chemoradiation therapy. Initially, conventional IMRT plans were created to maintain target coverage and reduce dose to OARs such as bladder, bowel, rectum, and femoral heads. Simulation FLT PET images were used to create IMRT plans to spare bone marrow identified as regions with SUV of 2 or greater (IMRT-BMS) within the pelvic bones from top of L3 to 5mm below the greater trochanter without compromising PTV coverage or OAR sparing when compared to the initial IMRT plan. IMRT-BMS plans used 8–10 beam angles that surrounded the subject. These plans were used for treatment. Retrospectively, the same simulation FLT PET images were used to create IMRT plans that spared bone marrow located in the sacral pelvic bone region (IMRT-FAN) also without compromising PTV coverage or OAR sparing. IMRT-FAN plans used 16 beam angles every 12° anteriorly from 90° – 270°. Optimization objectives for the sacral bone marrow avoidance region were weighted to reduce ≥V10. Results: IMRT-FAN reduced dose to the sacral bone marrow for all six subjects. The average V5, V10, V20, and V30 differences from the IMRT-BMS plan were −2.2 ± 1.7%, −11.4 ± 3.6%, −17.6 ± 5.1%, and −19.1 ± 8.1% respectively. Average PTV coverage change was 0.5% ± 0.8% from the conventional IMRT plan. Conclusion: An IMRT planning technique that uses beams from the anterior and lateral directions reduced the volume of sacral bone marrow that receives ≤10Gy while maintaining PTV coverage and OAR sparing. Additionally, the volume of sacral bone marrow that received 20 or 30 Gy was also reduced

    The aim of this retrospective study was to evaluate the main independent prognostic factors of negative maternal and fetal outcomes in a relatively large sample of pregnant outpatients (N=906) who were normotensive or affected by chronic hypertension, gestational hypertension, or preeclampsia. Among the studied parameters, the ones significantly associated with negative maternal outcomes were a diagnosis of preeclampsia (vs other forms of hypertension or normotension) and higher serum uric acid level, while antihypertensive treatment, number of previous deliveries, and blood pressure (BP) control at deliveries seemed to be protective. Regarding negative fetal outcomes, the parameters significantly associated with a negative maternal outcome were a diagnosis of preeclampsia (vs other forms of hypertension or normotension) and mother pre-pregnancy body mass index, while antihypertensive treatment and BP control at delivery seemed to be protective. Specific patient characteristics should help to predict the risk of negative maternal and fetal outcomes. PMID:26173048

    Background: the aim of the study was to assess the safety, efficacy and cost-effectiveness of negative Pressure wound therapy (nPT for people with chronic and acute wounds.

    Methods: the scope and the final draft of the report have been submitted to the stakeholders (producers, payers and patients. safety issues were addressed through a systematic review of the meta-literature. efficacy was addressed through a systematic review and meta-analysis of randomized controlled trials (rcTs comparing nPT and other standard therapies in patients with chronic or acute lesions. cost-consequence was analyzed through a systematic review of the existing studies.

    Results: we retrieved 19 studies, 13 of which were included in the meta-analysis. Many studies had biases that may have resulted in a better performance for nPT. nPT showed: a slightly shorter healing time (-10.4 days, p=0.001, with no heterogeneity, apart from one small study with very positive results, and 40% more patients healed (p=0.002, no heterogeneity.We identified 15 original research papers on nPT costs and cost per outcome. The costs-per-patient- treated varied from +29% to -60%, with several studies reporting savings for nPT.

    Conclusions: despite serious methodological flaws, the body of evidence available was sufficient to prove some clinical benefit of nPT in severe chronic and acute wound treatment. There is a need for independent and contextualized cost analyses....

    Full Text Available Stress-activated gene × environment interactions may contribute to individual variability in blood pressure reductions from behavioral interventions. We investigated effects of endothelin-1 (ET-1 LYS198ASN SNP and discriminatory stress exposure upon impact of 12-week behavioral interventions upon ambulatory BP (ABP among 162 prehypertensive African American adolescents. Following genotyping, completion of questionnaire battery, and 24-hour ABP monitoring, participants were randomized to health education control (HEC, life skills training (LST, or breathing awareness meditation (BAM. Postintervention ABP was obtained. Significant three-way interactions on ABP changes indicated that among ET-1 SNP carriers, the only group to show reductions was BAM from low chronic stress environments. Among ET-1 SNP noncarriers, under low chronic stress exposure, all approaches worked, especially BAM. Among high stress exposure noncarriers, only BAM resulted in reductions. If these preliminary findings are replicated via ancillary analyses of archival databases and then via efficacy trials, selection of behavioral prescriptions for prehypertensives will be edging closer to being guided by individual's underlying genetic and environmental factors incorporating the healthcare model of personalized preventive medicine.

  9. Coronal MR imaging of the normal 3rd, 4th, and 5th lumbar and 1st sacral nerve roots

    International Nuclear Information System (INIS)

    Seven healthy volunteers underwent coronal MR imaging at 1.5 tesla of the normal 3rd, 4th, and 5th lumbar, and 1st sacral nerve roots. Coronal slices, 3-mm-thick with a 0.3-mm gap between the slices were obtained (TR/TE 600/22) through the lumbar spinal canal. All the nerve roots were visible on at least one image. One can routinely expect to demonstrate the 3rd, 4th, and 5th lumbar, and 1st sacral nerve roots on T1-weighted, 3-mm-thick coronal MR scans. We found no correlation between the degree of lumbar lordosis and the lengths of the visible nerve roots. Five patients with one of the following spinal problems: anomaly, tumor, disk herniation, and failed back surgery syndrome were examined according to our protocol. In all these cases coronal MR imaging gave the correct diagnosis. (orig.)

    A variety of neuromodulation approaches have been described for the management of pelvic neuropathies, including interstitial cystitis, pudendal neuralgia and persistent genital arousal disorder. The benefits of a combined sacral and pudendal nerve neuromodulator has yet to be explored for these patients. In this report, we describe the case of a 35-year-old woman with a complex pelvic neuropathy resulting in urinary, sexual and gastro-intestinal dysfunction. She presented with an established diagnosis of interstitial cystitis; however, she also fulfilled diagnostic criteria for pudendal neuralgia and persistent genital arousal disorder. The patient underwent implantation of a combined sacral and pudendal nerve neuoromodulation device at the time of surgical decompression of the pudendal nerves. An impressive clinical response followed. This case demonstrates a unique clinical presentation and highlights the value of a combined surgical and neuromodulatory approach in the management of patients with complex pelvic neuropathies.

    Seven healthy volunteers underwent coronal MR imaging at 1.5 tesla of the normal 3rd, 4th, and 5th lumbar, and 1st sacral nerve roots. Coronal slices, 3-mm-thick with a 0.3-mm gap between the slices were obtained (TR/TE 600/22) through the lumbar spinal canal. All the nerve roots were visible on at least one image. One can routinely expect to demonstrate the 3rd, 4th, and 5th lumbar, and 1st sacral nerve roots on T1-weighted, 3-mm-thick coronal MR scans. We found no correlation between the degree of lumbar lordosis and the lengths of the visible nerve roots. Five patients with one of the following spinal problems: anomaly, tumor, disk herniation, and failed back surgery syndrome were examined according to our protocol. In all these cases coronal MR imaging gave the correct diagnosis. (orig.).

    Nitric oxide is a critical regulator of blood pressure (BP) and inflammation, and female spontaneously hypertensive rats (SHR) have higher renal nitric oxide bioavailability than males. We hypothesize that female SHR will have a greater rise in BP and renal T cell infiltration in response to nitric oxide synthase (NOS) inhibition than males. Both male and female SHR displayed a dose-dependent increase in BP to the nonspecific NOS inhibitor NG-nitro-l-arginine methyl ester (l-NAME: 2, 5, and 7...

    Background In August 2010, the Federal Joint Committee (G-BA) decided that negative pressure wound therapy (NPWT) would not be reimbursable in German ambulatory care. This decision was based on reports from the Institute for Quality and Efficiency in Health Care (IQWiG), which concluded that there is no convincing evidence in favor of NPWT. The aim of this diabetic foot study (DiaFu study) is to evaluate whether the clinical, safety and economic results of NPWT are superior to the results of ...

    Angiotensin-(1-7) improves glycemic control in animal models of cardiometabolic syndrome. The tissue-specific sites of action and blood pressure dependence of these metabolic effects, however, remain unclear. We hypothesized that Ang-(1-7) improves insulin sensitivity by enhancing peripheral glucose delivery. Adult male C57BL/6J mice were placed on standard chow or 60% high-fat diet for 11 weeks. Ang-(1-7) (400 ng/kg per minute) or saline was infused subcutaneously during the last 3 weeks of diet, and hyperinsulinemic-euglycemic clamps were performed at the end of treatment. High-fat fed mice exhibited modest hypertension (systolic blood pressure: 137±3 high fat versus 123±5 mm Hg chow;P=0.001), which was not altered by Ang-(1-7) (141±4 mm Hg;P=0.574). Ang-(1-7) did not alter body weight or fasting glucose and insulin in chow or high-fat fed mice. Ang-(1-7) increased the steady-state glucose infusion rate needed to maintain euglycemia in high-fat fed mice (31±5 Ang-(1-7) versus 16±1 mg/kg per minute vehicle;P=0.017) reflecting increased whole-body insulin sensitivity, with no effect in chow-fed mice. The improved insulin sensitivity in high-fat fed mice was because of an enhanced rate of glucose disappearance (34±5 Ang-(1-7) versus 20±2 mg/kg per minute vehicle;P=0.049). Ang-(1-7) enhanced glucose uptake specifically into skeletal muscle by increasing translocation of glucose transporter 4 to the sarcolemma. Our data suggest that Ang-(1-7) has direct insulin-sensitizing effects on skeletal muscle, independent of changes in blood pressure. These findings provide new insight into mechanisms by which Ang-(1-7) improves insulin action, and provide further support for targeting this peptide in cardiometabolic disease. PMID:26975707

  20. The response of right ventricular size, function, and pressure to supine exercise: A comparison of patients with chronic obstructive lung disease and normal subjects

    International Nuclear Information System (INIS)

    The response of right ventricular ejection fraction (RVEF) and right ventricular end-diastolic volume (RVEDV) to exercise was studied in 11 patients with severe (FEV25sub(%)sub(-)75sub(%)=0.32+-0.13, mean+-SD) chronic obstructive pulmonary disease (COPD). Using gated radionuclide cardiac blood pool imaging techniques, the response of the patients with COPD was compared with that of 15 control subjects. Arterial blood gases, pulmonary arterial pressures, wedge pressure, and right ventricular pressures also were monitored in patients with COPD. The resting RVEF was lower and the resting RVEDV was higher in patients with COPD than in normals (both, P2). With exercise this cardiac index rose to 5.52+-1.7/min/m2(P<0.01) due to the increase in heart rate (83+-18 to 125+-25 beats/min; P<0.01) while stroke volume did not significantly change. During exercise, normal subjects showed an increase in RVEF while RVEDV did not change; in patients with COPD, the RVEF fell and the RVEDV increased. In the patients with COPD, mild resting arterial hypoxemia and hypercapnia were both exaggerated during exercise; and mild resting pulmonary arterial hypertension (PAm=24.3+-7.65 mm Hg) also worsened with exercise (PAm=41+-19 mm Hg, P<0.01). Correlation between change in RVEF and PAm was -0.58, and between change in RVEDV and PAm was 0.63. We conclude that patients with severe COPD often have right ventricular dilation at rest and commonly respond to supine exercise with a fall in FV ejection fraction and further dilation of the right ventricle.

    Mismatch between the richness or species composition of a death assemblage (DA) and the local living assemblage (LA) is typically attributed to natural post-mortem processes, particularly preservational bias. Recent research, however, suggests that live-dead (LD) agreement is significantly lower in anthropogenically disturbed settings. This reflects the so-called "compositional inertia" of DAs to recent environmental change, i.e., DAs still capture earlier community states not affected by such disturbance. The inertia to changing ecological conditions should be particularly likely under conditions of anthropogenic modification because the rapidity of many human-driven changes is unprecedented in natural systems. Our research tests this hypothesis by evaluating the agreement between the LA and DA in benthic communities around the Zakum oil field in the Southern Arabian Sea, off the coast of the United Arab Emirates. This is an area of intense oil extraction, with almost 800 offshore oil and gas platforms and 25 major terminals, but no studies on the related impacts are widely available. This approach also sheds light on chronic pollution in tropical settings, an underrepresented topic in the literature. The size fraction between 2 and 5 mm was sorted for living molluscs and empty shells, which were then segregated to morphospecies and identified. The agreement was evaluated in terms of fidelity of species richness, evenness, and rank-order agreement. Compositional fidelity was also evaluated by multivariate analysis. The communities are dominated by bivalves. Polyplacophorans and scaphopods are occasionally present. Gastropod abundance is marginal compared to the bivalves, although their contribution is more significant when species diversity is taken into consideration. Moreover, the living assemblage in the studied size range was particularly poor in terms of species abundance.

    The ability to investigate microstructural properties of the central nervous system with diffusion tensor imaging (DTI) has been shown in many studies. More recently, DTI is being applied outside the brain showing promising results, for instance, for investigating muscle tissue. In this work, we demonstrate the feasibility of diffusion tensor imaging (DTI) and fiber tractography to study the nerves of the sacral plexus in humans in vivo and to assess the architectural configuration and microstructural properties of these peripheral nerves. For this research goal we optimized the acquisition parameters of a DTI sequence and acquired data from 10 healthy adults and one 12-year patient having spina bifida and neurogenic bladder dysfunction. For the healthy volunteers, we estimated the fractional anisotropy (FA) and mean (MD), axial (AD), and radial diffusivities (RD) of the sacral plexus nerves which may serve as a baseline for future studies. We demonstrated that tractography of the sacral plexus on a 3 Tesla MR scanner is feasible, giving 3D insight in the general anatomy and organization of the nerves L4 to S3. In addition, branches to the pudendal nerve were also found in 4 volunteers. There were no significant differences in any of the estimated diffusion measures between the right and left sided nerves or between the nerves L4 to S3 on an intra-subject basis. Furthermore, clinical feasibility of DTI and tractography in a child having spina bifida and neurogenic bladder dysfunction is demonstrated. The architectural configuration of the child's sacral plexus was comparable with the healthy volunteers and no significant disrupted nerve fibers were observed. However, there are strong indications that abnormal diffusion characteristics are present at the level of the neural tube defect due to incomplete segments of the nerves that are close to the vertebrae. These findings are encouraging for using DTI as a means to investigate changes in microstructural properties

    Full Text Available Penetrating injuries to the spine, although less common than motor vehicle accidents and falls, are important causes of injury to the spinal cord. They are essentially of two varieties: gunshot or stab wounds. Gunshot injuries to the spine are more commonly described. Stab wounds are usually inflicted by knife or other sharp objects. Rarer objects causing incidental spinal injuries include glass fragments, wood pieces, chopsticks, nailguns, and injection needles. Just few cases of penetrating vertebral injuries caused by pencil are described. The current case concerns a 42-year-old man with an accidental penetrating stonemason pencil injury into the vertebral canal without neurological deficit. After the self-removal of the foreign object the patient complained of a disabling orthostatic headache. The early identification and treatment of the intracranial hypotension due to the posttraumatic cerebrospinal fluid (CSF sacral fistulae were mandatory to avoid further neurological complications. In the current literature acute pattern of intracranial hypotension immediately after a penetrating injury of the vertebral column has never been reported.

  6. Chronic kidney disease, 24-h blood pressure and small vessel diseases are independently associated with cognitive impairment in lacunar infarct patients

    International Nuclear Information System (INIS)

    Although the relationships between chronic kidney disease (CKD) and cognitive impairment (CI) have been highlighted, the etiology of CI in CKD remains uncertain. Subjects comprised 224 consecutive patients with symptomatic lacunar infarction who underwent magnetic resonance imaging and ambulatory blood pressure monitoring (ABPM). Diurnal blood pressure (BP) patterns were categorized into three groups: dippers, non-dippers and risers. Lacunar infarcts (LIs), including both symptomatic and silent and diffuse white matter lesions (WMLs), were graded into three grades according to their degree. The results of kidney function were evaluated using estimated glomerular filtration rate (eGFR), categorized into three groups: stage 1, >60; stage 2, 30-60; and stage 3, -1 per 1.73 m2. There were 44 patients with CI. Confluent WMLs, including WML 2 and WML 3, were found in 36 patients (81.8%), and multiple lacunae including LI 2 and LI 3 were found in 30 patients (68.1%) with CI. Age >75 years (odds ratio (OR), 5.5; P-1 per 1.73 m2 (OR, 2.9; P-1 per 1.73 m2 (OR, 23.8; P75 years (OR, 4.1; P-1 per 1.73 m2 (OR, 3.7; P-1 per 1.73 m2 (OR, 8.7; P<0.05) were independently associated with WML grade 3. Extensive small vessel diseases, CKD and non-dipping status were independently associated with CI. CKD appears to mainly contribute to vascular CI, whereas possibilities of overlapping with other mechanisms such as degenerative CI cannot be excluded. Strict night time BP control and renoprotective treatment may be warranted to prevent CI. (author)

    Full Text Available Abstract Background Percutaneous sacro-iliac (SI screw fixation represents a widely used technique in the management of unstable posterior pelvic ring injuries and sacral fractures. The misplacement of SI-screws under fluoroscopic guidance represents a critical complication for these patients. This study was designed to determine the prevalence of sacral dysmorphia and the radiographic anatomy of surgical S1 and S2 corridors in a representative trauma population. Methods Prospective observational cohort study on a consecutive series of 344 skeletally mature trauma patients of both genders enrolled between January 1, 2007, to September 30, 2007, at a single academic level 1 trauma center. Inclusion criteria included a pelvic CT scan as part of the initial diagnostic trauma work-up. The prevalence of sacral dysmorphia was determined by plain radiographic pelvic films and CT scan analysis. The anatomy of sacral corridors was analyzed on 3 mm reconstruction sections derived from multislice CT scan, in the axial, coronal, and sagittal plane. "Safe" potential surgical corridors at S1 and S2 were calculated based on these measurements. Results Radiographic evidence of sacral dysmorphia was detected in 49 patients (14.5%. The prevalence of sacral dysmorphia was not significantly different between male and female patients (12.2% vs. 19.2%; P = 0.069. In contrast, significant gender-related differences were detected with regard to radiographic analysis of surgical corridors for SI-screw placement, with female trauma patients (n = 99 having significantly narrower corridors at S1 and S2 in all evaluated planes (axial, coronal, sagittal, compared to male counterparts (n = 245; P P = 0.06, implying S2 as a safe surgical corridor of choice in patients with sacral dysmorphia. Conclusions These findings emphasize a high prevalence of sacral dysmorphia in a representative trauma population and imply a higher risk of SI-screw misplacement in female patients

  8. Clinical application of preoperative embolization of tumor feeding artery combined with intraoperative balloon occlusion of the abdominal aorta in the resection of sacral tumors

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical application of preoperative embolization of tumor feeding artery combined with intraoperative balloon occlusion of the abdominal aorta in performing the surgical resection of sacral tumors. Methods: Conventional surgical excision of sacral tumors was employed in 24 patients with sacral tumors (control group), while preoperative embolization of tumor feeding artery combined with intraoperative balloon occlusion of the abdominal aorta was carried out in 32 patients with sacral tumors (study group). The operation time, blood loss during the surgery and the one-year recurrence rate of both groups were documented, and the results were statistically analyzed. Results: Angiography showed that in the study group the sacral tumors were supplied by several vessels, and these feeding arteries were occluded separately. The tumors were successfully removed in all patients with the help of intraoperative balloon occlusion of the abdominal aorta. During the surgery, the surgical area was clearly exposed and the blood loss wa remarkably reduced. After the surgery, no ectopic vascular embolization, renal ischemia, limb ischemia or other complications occurred. Statistically significant difference in the operation time, blood loss during the surgery and the one-year recurrence rate existed between the two groups (P<0.05). Conclusion: Preoperative embolization of tumor feeding artery combined with intraoperative balloon occlusion of the abdominal aorta can effectively shorten the operation time, reduce the blood loss during the surgery and provide a clear surgical field, and thus the surgical safety can be significantly ensured.

    Chlorhexidine-containing mouthwash (STRONG), which disturbs oral microflora, has been shown to diminish the rise in plasma nitrite concentration ([NO2-]) and attenuate the reduction in resting blood pressure (BP) typically seen after acute nitrate (NO3-) ingestion. We aimed to determine whether STRONG and weaker antiseptic agents attenuate the physiological effects of chronic NO3- supplementation using beetroot juice (BR). 12 healthy volunteers mouth-rinsed with STRONG, non-chlorhexidine mouthwash (WEAK) and deionised water (CON) 3 times a day, and ingested 70 mL BR (6.2 mmol NO3-), twice a day, for 6 days. BP (at rest and during 10 min of treadmill walking) and plasma and salivary [NO3-] and [NO2-] were measured prior to and on day 6 of supplementation. The change in salivary [NO3-] 4 h post final ingestion was higher (P0.05). However, during treadmill walking, the increase in systolic and mean arterial BP was higher 4 h after the final nitrate bolus in STRONG compared with CON (P<0.05) but not WEAK. The results indicate that both strong and weak antibacterial agents suppress the rise in plasma [NO2-] observed following the consumption of a high NO3- diet and the former can influence the BP response during low-intensity exercise.

    The ankle-brachial blood pressure index (ABPI) has been recognized to have a predictive value for cardiovascular (CV) events and mortality in general or dialysis populations. However, the associations between ABPI and those outcomes have not been fully investigated in predialysis patients. The present study aimed to clarify the relationships between ABPI and both CV events and mortality in Japanese chronic kidney disease (CKD) patients not on dialysis. In this prospective observational study, we enrolled 320 patients with CKD stages 3-5 who were not on dialysis. At baseline, ABPI was examined and a low ABPI was defined as ABPI were risk factors for CV events. It was demonstrated that age, a history of cerebrovascular disease and low ABPI were determined as independent risk factors for CV mortality. In addition, age, body mass index and low ABPI were independently associated with all-cause mortality. In patients with CKD, low ABPI during the predialysis period is independently associated with poor survival and CV events, suggesting the usefulness of measuring ABPI for predicting CV events and patient survival in CKD.

    This study aims to evaluate the acute effects of an oscillating positive expiratory pressure device (flutter) on airways resistance in patients with chronic obstructive pulmonary disease (COPD).Randomized crossover study: 15 COPD outpatients from Asthma Lab-Royal Brompton Hospital underwent spirometry, impulse oscillometry (IOS) for respiratory resistance (R) and reactance (X), and fraction exhaled nitric oxide (FeNO) measures.Thirty minutes of flutter exercises: a "flutter-sham" procedure was used as a control, and airway responses after a short-acting bronchodilator were also assessed.Respiratory system resistance (R): in COPD patients an increase in X5insp (-0.21 to -0.33 kPa/L/s) and Fres (24.95 to 26.16 Hz) occurred immediately after flutter exercises without bronchodilator. Following 20 min of rest, a decrease in the R5, ΔR5, R20, X5, and Ax was observed, with R5, R20, and X5 values lower than baseline, with a moderate effect size; there were no changes in FeNO levels or spirometry.The use of flutter can decrease the respiratory system resistance and reactance and expiratory flow limitation in stable COPD patients with small amounts of secretions.

  12. Imaging and treatment of spinal meningeal cysts in the lumbo-sacral region

    International Nuclear Information System (INIS)

    This paper presents the analysis of the symptomatic and asymptomatic cases of SMC and a review of the literature in order to evaluate the current position on treatment options for these lesions. Seventeen patients (5 men - 30% and 12 women - 70%, age, 17 to 68 years) diagnosed with SMC were studied. All examinations were performed with 1.5T (Picker Edge) using standard spine coil. Five symptomatic patients underwent surgery for cyst excision. In all of them, cysts were localized in lumbo-sacral region. MR examinations (from the level T12 to S3) allowed us to accurately classify diagnosed SMC. There were 10 cases of extradural SMC without spinal nerve root fibers (Type I) and 7 cases of extradural SMC with spinal nerve root fibers (Type II). Intradural SMC (type III) were not found in our series. In all cases type II SMC, MR examination did not reveal communication with the subarachnoid space. In two cases, cysts were extradural, and upon surgery could be dissected from dura and excised completely. In three cases, due to fibrous adhesions and involved nerve roots, the cysts were marsupialized. No obvious opening of the cysts to subarachnoid spaces was found. In all operated cases neurological improvement was recorded. Twelve months after surgery one patient had some minor groin numbness and one patient left lower extremity numbness. MRI is a sensitive and specific tool for SMC differentiation and it is helpful in pre-operative assessment. The cases of asymptomatic SMC in lumbosacral region should be thoroughly discussed between radiologist and neurosurgeon as to expanding properties of the lesions, and on that basis an option of a surgical treatment should be considered.

    Background Trans-sacral axial L5/S1 interbody fusion (AxiaLIF), a novel surgical procedure, recently adopted in clinical practice, has excellent clinical outcomes. However, there is inadequate data on the feasibility of the approach in all adult patients and the optimal surgical approach is currently unclear; therefore, further studies are required. In order to enhance the surgical approach for AxiaLIF, prospective anatomical imaging optimization is necessary. The objective of this study was to investigate the ability of magnetic resonance imaging (MRI) to achieve an optimal procedural setting.Methods The subjects (n=40) underwent lumbosacral MRI examination. The median sagittal MRI images were analyzed and four measurement markers were defined as follows: the center of the L5/S1 disc (A), the anterior margin of the S1/2 disc space (B), the sacrococcygeal junction (C), and the coccygeal tip (D). The measurement markers were connected to each other to produce five lines (AB, AC, AD, BC, and BD), as reference lines for surgical approaches. The distance between each reference line and the anterior and posterior margins of the L5 and S1 vertebral bodies was measured to determine the safety of the respective approaches.Results In all patients, Lines AB and AC satisfied the imaging safety criteria. Line AB would result in a significant deviation from the median and was determined to be unsuitable for AxiaLIF. Line AD satisfied the imaging safety criteria in 39 patients. However, the anal proximity of the puncture point proved to be limiting. For lines BC and BD, the imaging safety criteria were satisfied in 70% and 45% of patients, respectively.Conclusions The AxiaLIF procedure is a safe technique for insertion of fusion implants in all subjects. Line AC is a favorable reference line for surgical approach and safe for all subjects, while line BC is not suitable for all subjects.

    Full Text Available Meningoceles intra-sacrais são lesões raras, que podem determinar sintomas de compressão radicular. Descrevemos o caso de uma paciente de 18 anos, com queixa de incontinência urinária, acometida por esta patologia. Após avaliação neuro-urológica e estudo uro-dinâmico, foi demonstrada arreflexia do detrusor, sendo aventada a hipótese de disrafismo espinhal. O diagnóstico de meningocele intra-sacral oculta foi evidenciado através de ressonância magnética. A paciente foi submetida a abordagem cirúrgica com boa recuperação pós-operatória. No presente artigo, é feita breve revisão da literatura, e são discutidas as apresentações clínicas possíveis, os achados neuro-radiológicos e o tratamento cirúrgico.Intrasacral meningoceles are rare conditions that can cause symptoms of nerve root compression. We report a case of a 18-year-old female, who presented with urinary incontinence. The neurological and urological evaluation revealed lack of detrusor muscle reflex. This finding supported the hypothesis of spinal disraphism. Magnetic resonance image revealed an intrasacral meningocele. The patient was submitted to surgical excision of the lesion without postoperative complications. In the present paper, the pathogenesis, clinical picture, neuroradiological findings and surgical treatment are discussed.

    OBJECTIVE Tarlov cysts (TCs) occur most commonly on extradural components of the sacral and coccygeal nerve roots. These lesions are often found incidentally, with an estimated prevalence of 4%-9%. Given the low estimated rates of symptomatic TC and the fact that symptoms can overlap with other common causes of low-back pain, optimal management of this entity is a matter of ongoing debate. Here, the authors investigate the effects of surgical intervention on symptomatic TCs and aim to solidify the surgical criteria for this disease process. METHODS The authors performed a retrospective review of data from consecutive patients who were surgically treated for symptomatic TCs from September 2011 to March 2013. Clinical evaluations and results from surveying pain and overall health were used. Univariate statistical analyses were performed. RESULTS Twenty-three adults (4 males, 19 females) who had been symptomatic for a mean of 47.4 months were treated with laminectomy, microsurgical exposure and/or imbrication, and paraspinous muscle flap closure. Eighteen patients (78.3%) had undergone prior interventions without sustained improvement. Thirteen patients (56.5%) underwent lumbar drainage for an average of 8.7 days following surgery. The mean follow-up was 14.4 months. Univariate analyses demonstrated that an advanced age (p = 0.045), the number of noted perineural cysts on preoperative imaging (p = 0.02), and the duration of preoperative symptoms (p = 0.03) were associated with a poor postoperative outcome. Although 47.8% of the patients were able to return to normal activities, 93.8% of those surveyed reported that they would undergo the operation again if given the choice. CONCLUSIONS This is one of the largest published studies on patients with TCs treated microsurgically. The data suggest that patients with symptomatic TCs may benefit from open microsurgical treatment. Although outcomes seem related to patient age, duration of symptoms, and extent of disease

    Epidural injections are commonly performed blindly in veterinary medicine. The aims of this study were to describe the lumbosacral ultrasonographic anatomy and to assess the feasibility of an ultrasound-guided epidural injection technique in dogs. A cross sectional anatomic atlas of the lumbosacral region and ex vivo ultrasound images were obtained in two cadavers to describe the ultrasound anatomy and to identify the landmarks. Sixteen normal weight canine cadavers were used to establish two variations of the technique for direct ultrasound-guided injection, using spinal needles or epidural catheters. The technique was finally performed in two normal weight cadavers, in two overweight cadavers and in five live dogs with radiographic abnormalities resulting of the lumbosacral spine. Contrast medium was injected and CT was used to assess the success of the injection. The anatomic landmarks to carry out the procedure were the seventh lumbar vertebra, the iliac wings, and the first sacral vertebra. The target for directing the needle was the trapezoid-shaped echogenic zone between the contiguous articular facets of the lumbosacral vertebral canal visualized in a parasagittal plane. The spinal needle or epidural catheter was inserted in a 45° craniodorsal-caudoventral direction through the subcutaneous tissue and the interarcuate ligament until reaching the epidural space. CT examination confirmed the presence of contrast medium in the epidural space in 25/25 dogs, although a variable contamination of the subarachnoid space was also noted. Findings indicated that this ultrasound-guided epidural injection technique is feasible for normal weight and overweight dogs, with and without radiographic abnormalities of the spine. PMID:25187175

  17. Re: Effect of Sacral Neuromodulation on Female Sexual Function and Quality of Life: Are They Correlated?

    Full Text Available Sacral neuromodulation (SNM has become an established therapy for voiding dysfunction (VD. There have been published papers that documented improvement in bowel functions and bladder pain via SNM. However, improvement in female sexual function (FSF after SNM treatment remains unclear. Recently, Banakhar et al. evaluated the effects of SNM on FSF and its impact on quality of life (QoL and analyzed any correlation. They evaluated 33 female patients who were treated with SNM for VD. All patients completed the Female Sexual Function Index (FSFI, the 36-Item Short-Form Health Survey (SF-36, and incontinence questionnaires (the Urinary Distress Inventory [UDI-6] preoperatively and 4 months postoperatively. Ten patients were excluded from the study because they were not sexually active. The indications were: refractory overactive bladder in 19, frequency urgency syndrome in 2, and non-obstructive urinary retention in another 2 patients. SNM therapy significantly improved the total FSFI score (p=0.011. When the SF-36 and UDI-6 scores were compared, QoL showed significant improvement after SNM treatment. However, improvement in FSFI scores was not correlated with improvement in QoL. SNM therapy is an effective treatment modality in selected patient groups. In our country, SNM therapy has become a new option in the treatment of lower urinary tract problems. According to the results of this study, it is too early to conclude that SNM certainly improve FSF and QoL. The study just evaluated 23 cases. In order to have a more discrete conclusion, we need prospective trials with larger series

    2016-07-01

    To examine how the median sacral artery (MSA) is involved with the coccygeal body or glomus coccygeum, we studied serial frontal or sagittal sections of 14 embryos (approximately 5-6 weeks of gestation) and 12 fetuses (10-18 weeks). At five weeks, the caudal end of the dorsal aorta (i.e., MSA) accompanied putative sympathetic ganglion cells in front of the upper coccygeal and lower sacral vertebrae. At six weeks, a candidate for the initial coccygeal body was identified as a longitudinal arterial plexus involving nerve fibers and sympathetic ganglion cells between arteries. At 10-18 weeks, the MSA exhibited a highly tortuous course at the lower sacral and coccygeal levels, and was attached to and surrounded by veins, nerve fibers, and sympathetic ganglion cells near and between the bilateral origins of the levator ani muscle. Immunohistochemistry demonstrated expression of tyrosine hydroxylase and chromogranin A in the nerves. However, throughout the stages examined, we found no evidence suggestive of an arteriovenous anastomosis, such as well-developed smooth muscle. An acute anterior flexure of the vertebrae at the lower sacrum, as well as regression of the secondary neural tube, seemed to induce arterial plexus formation from an initial straight MSA. Nerves and ganglion cells were likely to be secondarily involved with the plexus because of the close topographical relationship. However, these nerves might play a major role in the extreme change into adult morphology. An arteriovenous anastomosis along the MSA might be an overinterpretation, at least in the prenatal human.

    Sacral fracture after lumbosacral instrumentation could be a source of prolonged pain and a late autonomy recovery in old patients. Diagnosis remains difficult and usually delayed. No clear consensus for efficient treatment of this complication has been defined. Aim of this study was to determine how to manage them. Three patients who sustained sacral fracture after instrumented lumbosacral fusion performed for degenerative disease of the spine are discussed. History, physical examinations' findings and radiographic features are presented. Pertinent literature was analyzed. All patients complained of unspecific low back and buttock pain a few weeks after index surgery. Diagnosis was done on CT-scan. We always choose revision surgery with good functional results. Sacral stress fracture has to be reminded behind unspecific buttock or low back pain. CT-scan seems to be the best radiological test to do the diagnosis. Surgical treatment is recommended when lumbar lordosis and pelvic incidence mismatched. PMID:26796998

  1. Trans-iliosacral plating for vertically unstable fractures of sacral spine associated with spinopelvic dissociation: A cadaveric study

    2012-01-01

    Conclusions: Trans-iliosacral plating is feasible anatomically, biomechanically and radiologically for sacral fractures associated with vertical shear pelvic fractures. Low profile of plate reduces the risk of hardware prominence and decreases the need for implant removal. Also, the fixation pattern of plate allows to spare mobile lumbosacral junction which is an important segment for spinal mobility. Biomechanical studies revealed that rigidity offered by plate for cross headed displacement across fracture site is equal to sacroiliac screws and further rigidity of construct can be increased with addition of one more screw. There is need for precountered thicker plate in future.

    Childhood maltreatment (CM) has been associated with an increased risk of nonspecific chronic low back pain (nsCLBP). However, the mechanisms underlying this association are unclear. Therefore, this study considered whether distinct types of CM are accompanied by specific alterations in somatosensory function. A total of 176 subjects with nsCLBP and 27 pain-free controls (PCs) were included. The Childhood Trauma Questionnaire (CTQ) was used to categorize patients into 2 groups (abused/neglected vs nonabused/nonneglected) for 5 types of CM (emotional abuse, physical abuse, sexual abuse, emotional neglect, and physical neglect). The standardized quantitative sensory testing protocol of the "German Research Network on Neuropathic Pain" was performed to obtain comprehensive profiles on somatosensory function, including detection and pain thresholds, pain sensitivity, and assessments of temporal summation (wind-up). Between 17.7% and 51.4% of subjects with nsCLBP reported CM, depending on the type of CM. Childhood Trauma Questionnaire subscores for emotional and sexual abuse were significantly higher in subjects with nsCLBP than in PCs. Compared with PCs, subjects with CM showed reduced pressure pain thresholds (PPTs), irrespective of the type of CM. Regarding distinct types of CM, subjects with nsCLBP with emotional abuse reported significantly higher wind-up than those without, and sexual abuse was accompanied by enhanced touch sensitivity. Our findings suggest that CM is nonspecifically associated with a decreased PPT in nsCLBP. Emotional abuse apparently leads to enhanced spinal pain summation, and sexual abuse leads to enhanced touch sensitivity. These results emphasize the importance of emotional abuse in nsCLBP and suggest that CM can induce long-term changes in adult somatosensory function. PMID:27075429

  5. Magnetic resonance imaging of morphological and functional changes of the uterus induced by sacral surface electrical stimulation

    International Nuclear Information System (INIS)

    The purpose of this study is to examine the morphological and kinematical changes of the uterus induced by electrical stimulation applied to the skin just above the second and fourth posterior sacral foramens (sacral surface electrical stimulation [ssES]) in 26 healthy subjects. Out of them, eight subjects who had severe pain subjectively during every menstruation received ssES just in menstruation. Morphological and functional changes of the uterus were examined by using T2-weighted magnetic resonance (MR) imaging and T1-weighted MR cinematography, respectively. Cyclic electrical stimulation for 15 min with 5 sec ON and 5 sec OFF was applied just before MR scanning. A decrease in thickness of the muscular layer of the uterus was observed in every subject after ssES for 15 min and was significant as compared with the thickness before ssES. Periodic uterine movement during menstruation was observed in the subjects with severe menstrual pain in MR cine and the power spectrum analysis of the movement showed a marked decrease in peak power and frequency after ssES treatment. We conclude that ssES causes a reduction of static muscle tension of the uterus in all menstrual cycle periods and suppression of uterine peristalsis during menstruation in the subjects with severe menstrual pain. Possible neural mechanisms for these static and dynamic effects of ssES on the uterus at spinal level are discussed. (author)

    Sacral insufficiency fractures pose a diagnostic problem because of the nonspecific clinical signs and the absence of distinguishing features in standard radiological studies. The main causes are osteoporosis, making women reaching the age of menopause among the populations most commonly affected, and a history of radiotherapy, leading to the inclusion of neoplastic disease in the differential diagnosis. The characteristic site is ala sacralis, usually bilateral, and the fracture is vertical, running parallel to the sacroiliac joints. The sacral bone may also be involved (H pattern), as well as the medial region of the ilium. It is frequently associated with fractures of the supraacetabular region and the pubic symphysis. Computed tomography is the technique of choice for detecting the fracture line and/or sclerosis, although it is less sensitive than magnetic resonance (MR) imaging or scintigraphy during acute phases. MR of the above regions shows nonspecific edema, contrasting with hypointense signals indicating the general path of the fracture line in T2-weighted images. The use of gadolinium or fat suppression greatly increases the sensitivity. Bone scintigraphy is a highly sensitive diagnostic tool, although the H pattern occurs in less than 50% of cases.

    The sacrum, by virtue of its anatomic location plays a key role in providing stability and strength to the pelvis. Presence of intervertebral discs in sacrum and coccyx is rare. Knowledge of its variations is of utmost importance to surgeons and radiologists. The current study focused on the presence of intervertebral discs between the sacral and coccygeal vertebrae in south Indian cadaveric pelvises. We observed 56 adult pelvises of which, 34 (61%) pelvises showed the presence of intervertebral discs between the sacral vertebrae and between the coccygeal vertebrae, while 22 (39%) pelvises did not have the intervertebral discs either in the sacrum or the coccyx. We also found that most of the specimens had discs between S1 and S2 vertebrae (39%), followed by, between S4 and S5 (18%), between S2–S3 (14%) and least being between S3–S4 (13%). In the coccyx it was found that 7% of pelvises had disc between Co1-Co2, 4% of them had between Co2-Co3 and 4% had between Co3-Co4. Knowledge regarding such anatomic variations in the sacro-coccygeal region is important to note because they require alterations in various instrumentation procedures involving the sacrum.

    2016-01-01

    AIM: To investigate the nature and severity of AE related to sacral neurostimulation (SNS). METHODS: Based on Pubmed and Embase searches, we identified published trials and case series of SNS for fecal incontinence (FI) and extracted data on adverse events, requiring an active intervention. Those problems were operationally defined as infection, device removal explant or need for lead and/or generator replacement. In addition, we analyzed the Manufacturer and User Device Experience registry of the Federal Drug Administration for the months of August - October of 2015. Events were included if the report specifically mentioned gastrointestinal (GI), bowel and FI as indication and if the narrative did not focus on bladder symptoms. The classification, reporter, the date of the recorded complaint, time between initial implant and report, the type of AE, steps taken and outcome were extracted from the report. In cases of device removal or replacement, we looked for confirmatory comments by healthcare providers or the manufacturer. RESULTS: Published studies reported adverse events and reoperation rates for 1954 patients, followed for 27 (1-117) mo. Reoperation rates were 18.6% (14.2-23.9) with device explants accounting for 10.0% (7.8-12.7) of secondary surgeries; rates of device replacement or explant or pocket site and electrode revisions increased with longer follow up. During the period examined, the FDA received 1684 reports of AE related to SNS with FI or GI listed as indication. A total of 652 reports met the inclusion criteria, with 52.7% specifically listing FI. Lack or loss of benefit (48.9%), pain or dysesthesia (27.8%) and complication at the generator implantation site (8.7%) were most commonly listed. Complaints led to secondary surgeries in 29.7% of the AE. Reoperations were performed to explant (38.2%) or replace (46.5%) the device or a lead, or revise the generator pocket (14.6%). Conservative management changes mostly involved changes in stimulation

    To prove the feasibility of using Hounsfield attenuation values at MDCT to detect bone bruises related to sacral insufficiency fractures. Twenty-two patients with acute sacrum trauma and no fracture findings at MDCT were included in our prospective study. Two observers independently reviewed CTs regarding visual signs of bone bruises in 132 defined regions of the sacral alae. Interobserver agreement was tested by {kappa} statistics. Subsequently, HU values were obtained in the same regions, and attenuation differences between the two sides were calculated. Validity and reliability were assessed by intraclass correlation coefficient and Bland-Altman analysis. HU differences were subjected to ROC curve analysis to determine sensitivity, specificity, PPV and NPV. MRI served as standard reference. MRI revealed 19 regions with bone bruises and associated sacral insufficiency fractures. HU measurements demonstrated good validity and reliability (r = 0.989). ROC curve analysis exhibited an ideal cutoff value of 35.7 HU density difference between affected and non-affected regions. Visual evaluation revealed moderate agreement ({kappa} = 0.48); diagnostic accuracy was inferior to objective evaluation. Assessment of differences in bone marrow density by HU measurements is an objective and reliable tool for detection of bone bruises associated with occult sacral insufficiency fractures. (orig.)

    To evaluate the incidence of sacral insufficiency fracture in osteoporotic patient with compression fracture of the thoracolumbar (T-L) spine on magnetic resonance image (MRI), and to analyze the correlation of variable clinical factors and the incidence of sacral insufficiency fracture. We retrospectively reviewed 160 patients (27 men, 133 women; age range of 50 to 89 years) who underwent spinal MRI and had compression fracture of the T-L spine. Compression fractures due to trauma or tumor were excluded. We evaluated the incidence of sacral insufficiency fracture according to the patients' age, sex, number of compression fractures, and the existence of bone marrow edema pattern of compression fracture. During the same period, we evaluated the incidence of spinal compression fracture in the patients of pelvic insufficiency fracture. Out of the 160 patients who had compression fracture in the T-L spine, 17 (10.6%) had insufficiency fracture of the sacrum. Compression fracture occurred almost 5 times more frequently in women (27:133), but the incidence of sacral insufficiency fracture was 2/27 for men (7.4%) and 15/133 for women (11.3%), with no statistically significant difference ({rho} = 0.80). According to age, the ratio of insufficiency fracture to compression fracture was 0% (0/23) in the 50's, 10.6% (7/66) in the 60's, 12.5% (7/56) in the 70's, and 20.0% (3/15) in the 80's. In respect of single and multiple compression fracture, the incidence of sacral insufficiency fracture was 8/65 for men (12.3%) and 9/95 for women (9.5%), showing no significant difference ({rho} = 0.37). In the patients with and without compression fracture with bone marrow edema, insufficiency fracture occurred in 5/76 (6.6%) and 12/84 (14.3%), respectively. On the other hand, of the 67 patients who had pelvic insufficiency fracture, 27 (40.3%) also had spinal compression fracture. About 10% of the patients with osteoporotic compression fracture in the T/L spine

    Background Respiratory muscle fatigue plays an important role in acute exacerbations of chronic obstructive pulmonary disease (AECOPD). In previous clinical studies, non-invasive positive pressure ventilation (NPPV) was proved to be successful only for AECOPD patients with severe respiratory failure. We hypothesized that, the outcomes of AECOPD would be improved if NPPV is early (within 24 to 48 hours of admission) administered in those patients with respiratory muscle fatigue and mild respiratory insufficiency, especially in patients without fulfilling the conventional criteria of mechanical ventilatory support. Methods A prospective multicentre randomized controlled trial was conducted in 19 hospitals in China over 16 months. Three hundred and forty-two AECOPD patients with pH≥7.25 and PaCO2>45 mmHg were recruited on general ward and randomly assigned to standard medical treatment (control group) or early administration of additional NPPV (NPPV group).Results The characteristics of two groups on admission were similar. The number of AECOPD patients requiring intubations in NPPV group was much fewer than that of the control group (8/171 vs 26/71, P=0.002). Subgroup analysis showed the needs for intubation in mildly (pH≥7.35) and severe (pH<7.30) acidotic patients in NPPV group were both decreased (9/80 vs 2/71, P=0.047 and 8/30 vs 3/43, P=0.048, respectively). The mortality in hospital was reduced slightly by NPPV but with no significant difference (7/171 vs 12/171, P=0.345). Respiratory rate (RR),scale for accessory muscle use and arterial pH improved rapidly at the first 2 hours only in patients of NPPV group. After 24 hours, the differences of pH, PaO2, scale for accessory muscle use and RR in NPPV group [(7.36±0.06) mmHg, (72±22) mmHg, (2.5±0.9)/min, (22±4)/min] were statistically significant compared with control group (7.37±0.05) mmHg, (85±34) mmHg, (2.3±1.1)/min, (21±4)/min, P<0.01 for all comparisons].Conclusions The early use of NPPV on

    Blood pressure is the force of blood against artery walls. It is measured in millimeters of mercury (mm Hg) and recorded as two numbers: systolic pressure (as the heart contracts) over diastolic pressure (as the heart relaxes between beats). High blood pressure (hypertension) is defined as chronically elevated high blood pressure, with systolic blood pressure (SBP) of 140 mm Hg or greater, and diastolic blood pressure (DBP) of 90 mm Hg or greater.

  15. Relative Importance of Hip and Sacral Pain Among Long-Term Gynecological Cancer Survivors Treated With Pelvic Radiotherapy and Their Relationships to Mean Absorbed Doses

    International Nuclear Information System (INIS)

    Purpose: To investigate the relative importance of patient-reported hip and sacral pain after pelvic radiotherapy (RT) for gynecological cancer and its relationship to the absorbed doses in these organs. Methods and Materials: We used data from a population-based study that included 650 long-term gynecological cancer survivors treated with pelvic RT in the Gothenburg and Stockholm areas in Sweden with a median follow-up of 6 years (range, 2–15) and 344 population controls. Symptoms were assessed through a study-specific postal questionnaire. We also analyzed the hip and sacral dose-volume histogram data for 358 of the survivors. Results: Of the survivors, one in three reported having or having had hip pain after completing RT. Daily pain when walking was four times as common among the survivors compared to controls. Symptoms increased in frequency with a mean absorbed dose >37.5 Gy. Also, two in five survivors reported pain in the sacrum. Sacral pain also affected their walking ability and tended to increase with a mean absorbed dose >42.5 Gy. Conclusions: Long-term survivors of gynecological cancer treated with pelvic RT experience hip and sacral pain when walking. The mean absorbed dose was significantly related to hip pain and was borderline significantly related to sacral pain. Keeping the total mean absorbed hip dose below 37.5 Gy during treatment might lower the occurrence of long-lasting pain. In relation to the controls, the survivors had a lower occurrence of pain and pain-related symptoms from the hips and sacrum compared with what has previously been reported for the pubic bone.

    Full Text Available The purpose of the paper is the identification and interpretation of the dynamically developing contemporary mass event called the Cavalcade of the Three Kings (Orszak Trzech Króli. It was organised for the first time in 2009 in Warsaw. On the 6th of January 2014, about 630, 000 inhabitants of 177 towns and villages, singing Christmas carols and wearing colourful crowns on their heads, publically celebrated the religious feast of Epiphany. In the author's opinion, the cavalcades can be perceived as a new phenomenon in public spaces placed between sacralization and festivalization because they have some components of religious events and festivals but they are neither. They seem to be a new hybrid event, with religious and festive elements.

    The function of the urinary bladder is partly controlled by parasympathetic preganglionic neurons (PPNs) of the sacral parasympathetic nucleus (SPN). Our recent work demonstrated that endomorphin-2 (EM-2)-immunoreactive (IR) terminals form synapses with μ-opioid receptor (MOR)-expressing PPNs in the rat SPN. Here, we examined the effects of EM-2 on excitatory synaptic transmission and the neuronal excitability of the PPNs in young rats (24–30 days old) using a whole-cell patch-clamp approach....

    To evaluate time efficiency, radiation dose, precision and complications of percutaneous iliosacral screw placement under CT-guidance in local anaesthesia. Retrospective analysis of 143 interventions in 135 patients during a period of 42 months. Implant failures could be evaluated in 85/182 screws and bony healing or refracturing in 46/182 screws. A total of 182 iliosacral screw placements in 179 vertical sacral fractures (105 unilateral, 37 bilateral) took place in 135 patients. 166/179 of the sacral fractures were detected in Denis zone 1, 10 in Denis zone 2 and 3 in Denis zone 3. No screw misplacements including the simultaneous bilateral procedures were noted. The average time for a unilateral screw placement was 23 minutes (range: 14-52 minutes) and 35 minutes (range: 21-60 minutes) for simultaneous bilateral screwing. The dose length product was 365 mGy x cm (range: 162-1014 mGy x cm) for the unilateral and 470 mGy x cm (range: 270-1271 mGy x cm) for the bilateral procedure. 1 gluteal bleeding occurred as the only acute minor complication (0.7%). Fracture healing was verified with follow-up CTs in 42/46 sacral fractures after screw placement. Backing out occurred in 12/85 screws between 6 and 69 days after intervention. In 8 patients contralateral stress fractures were detected after unilateral screw placement between day 10 and 127 (average: 48 days). CT-guided iliosacral screw placement in sacral fractures is a safe tool providing a very high precision. The radiation dose is in the order of a diagnostic CT of the pelvis for both unilateral and bilateral screws. Contralateral stress fractures in unilateral screw placements have to be considered during the first weeks after intervention.

    This study demonstrates that a Doppler-derived tricuspid flow velocity pattern provides an accurate, feasible, and noninvasive method of estimating and monitoring mean right atrial pressure in patients with heart failure due to left ventricular systolic dysfunction, and who are both in sinus rhythm and atrial fibrillation. In particular, the acceleration rate of early right ventricular filling is a powerful and independent predictor of mean right atrial pressure. PMID:9485149

    Our goal was to assess the technical results in patients who underwent long-axis sacroplasty for the treatment of sacral insufficiency fractures (SIF) by radiofrequency-induced high-viscosity bone cement augmentation. Twelve patients with bilateral sacral fractures were treated by augmentation with radiofrequency-activated, high-viscosity polymethylmethacrylate (PMMA) bone cement under local anesthesia. CT-guided sacroplasty was performed by using a long-axis approach through a single entry point. Thirty-six vertebrae were treated in 12 sessions under a combination of CT and fluoroscopic guidance using a bilateral access and a cavity-creating osteotome prior to remote-controlled, hydraulically driven cement injection. The visual analogue scale (VAS) score before sacroplasty and at 1 and 3 months after the treatment was obtained. PMMA leaks were evaluated retrospectively using the post-interventional CT. The mean amount of high-viscosity PMMA injected per patient was 7.8 ml. No major adverse events were observed. In the first 4 days after the procedure, the mean VAS score decreased from 8.1 ± 1.9 to mean 3.1 ± 1.2 and was followed by a gradual but continuous decrease throughout the rest of the follow-up period at 24 weeks (mean 2.2 ± 1.1) and 48 weeks (mean 2.1 ± 1.4). CT fluoroscopy-guided sacral augmentation was safe and effective in all 12 patients with osteoporotic SIF. (orig.)

    Full Text Available JUSTIFICATIVA E OBJETIVOS: O objetivo deste estudo foi desenvolver uma técnica simples e prática para a cateterização crônica em canal peridural sacral de coelhos. MÉTODOS: O estudo incluiu dez coelhos com peso entre 2 e 2,5 kg. Após a anestesia e a analgesia, colocamos um cateter peridural através de uma incisão longitudinal de 2 cm na cauda acima da região do hiato sacral. Confirmamos a localização com a administração de lidocaína a 1% (nivelamento da perda sensorial e da função motora dos membros inferiores. O cateter foi introduzido através de um túnel subcutâneo até o pescoço, onde foi fixado. RESULTADOS: A implantação de cateter crônico peridural caudal foi bem-sucedida em todos os coelhos. Os cateteres permaneceram eficazmente no lugar por dez dias, sem intercorrências durante esse período. A localização do cateter foi reconfirmada por lidocaína a 1% no último dia. Após matar os animais, procedeu-se laminectomia para localização do cateter no espaço peridural. CONCLUSÕES: Há vários métodos de cateterização do espaço peridural em modelos animais na literatura. A cateterização do espaço peridural em coelhos pode ser feita através das vias atlanto-occipital, lombar ou caudal por amputação da cauda. As técnicas de cateterização intratecal e peridural descritas na literatura exigem perícia cirúrgica e conhecimento de procedimentos cirúrgicos, como laminectomia e amputação da cauda. A nossa técnica não requer grande habilidade cirúrgica, a integridade anatômica foi preservada e não houve mau posicionamento de cateter. Em conclusão, podemos sugerir que a nova técnica de cateterização peridural é simples, facilmente aplicável e pode ser usada em estudos experimentais de modelos animais.

    Penetrating injury to the rectum,vertebral body and spinal cord by a steel rod is a rare condition.Treatment of this kind of injury is very challenging.Rectal injury requires repair and fecal diversion,while debridement of the spine is difficult,especially when the injury site is very long.Here we report a case of penetrating injury of rectum and sacral vertebra by a steel rod after falling onto the ground from 1 m height.The abscess cavity was irrigated with 3% hydrogen peroxide and physiological saline repeatedly.The bony canal was carefully debrided,curetted and bony fragments were removed.Spinal irrigation and drainage lasted for 2 months and sensitive antibiotic (amikacin sulfate) was given 7 days after surgery,but abscess was still formed in the vertebral canal.At 6-month follow-up,the patient was paralyzed without any neurological improvement,and the pain in low back and lower limb still continued.

  7. The sacral perineural system: Are there radiological criteria an indication for surgery? First results and literature survey

    International Nuclear Information System (INIS)

    Purpose: To establish recommendations for diagnostic imaging of cystic lesions of the sacral region and to evaluate for potential predictors of therapeutic outcome. Methods: Conventional imaging of the lumbar spine, conventional CT, myelography, post myelo-CT and MRI were performed in 7 symptomatic patients. All patients underwent operative decompression and histological examination. The radiographic examinations were reevaluated retrospectively and correlated with the postoperative outcome. Results: In one patient the differential diagnosis of a neurinoma could not be excluded with CT and CT-myelography alone. In all 7 patients MRI provided a definite diagnosis and a precise presentation of the cyst extension. A complete postoperative remission of symptoms was noticed in 4, a partial remission in three cases. The correlation of cyst extension, cyst shape, and the communication with the subarachnoid space did not provide predictive information concerning operative outcome. Conclusion: MR can be used as the sole imaging tool for demonstration of cystic lesions. Relevant disadvantages in comparison to myelography and myelo-CT were not evident. No imaging modality could predict the value of surgical intervention. (orig.)

    Anemia of chronic disease (ACD) is thought to impair the responsiveness of erythroid progenitor cells, but research has shown treatment with recombinant human erythropoietin (rhuEPO) can improve patient hemoglobin levels and, subsequently, overall patient health status and quality of life. A prospective pilot study was designed to estimate the prevalence of ACD in outpatients with spinal cord injury (SCI) and chronic pressure ulcers (PUs) and examine the impact of rhuEPO on PU healing in this population. The charts of 49 SCI patients with PUs were reviewed; of those, 17 had anemia (hemoglobin nutritional status and treatment response. No statistically significant changes were observed with treatment. Wound surface area and depth had mean decreases of 1.35 cm(2) and 0.58 cm, respectively, immediately post-treatment. Participants' elevated C-reactive protein levels (91.1-14.2 mg/L) decreased with rhuEPO treatment, but returned to baseline levels post-treatment (83.2-14.3 mg/L). Prealbumin levels were consistently low (range of 0.1-0.21 g/L). This research indicates rhuEPO treatment may improve some outcomes for ACD-SCI PU patients, but larger randomized controlled trials are required. The results of this study suggest the prevalence of ACD in the SCI outpatient population with PUs is at least 35%, and increased vigilance of patient nutrition is recommended. PMID:26061404

    International Nuclear Information System (INIS)

    Purpose: to investigate whether diffusion-weighted imaging (DWI) in magnetic resonance imaging (MRI) provides additional information about the periventricular white matter for the assessment of hydrocephalus. Materials and methods: sixteen MRI examinations (11 with acutely increased cerebral pressure, 5 without symptoms) on 15 patients with hydrocephalus (4 patients with communicating hydrocephalus and 11 patients with obstructive hydrocephalus) were analyzed. One symptomatic patient subsequently became asymptomatic. We investigated the ''apparent diffusion coefficient'' (ADC) in the subcortical and periventricular white matter. The ADCs of the study patients were compared with those of a healthy control group. Results: symptomatic patients with hydrocephalus, 6/11 showed periventricular edema and a significantly higher ADC values in the periventricular region than in the subcortical white matter. 5/11 symptomatic patients showed significantly higher ADC values even in the absence of periventricular interstitial edema (both groups contained patients with communicating and obstructive hydrocephalus). All 5 asymptomatic patients with hydrocephalus did not have a significantly higher ADC values in the periventricular region. Conclusion: in patients with hydrocephalus and acutely increased cerebral pressure, DWI showed a significantly higher ADC values in the periventricular region even without visible interstitial edema on conventional MRI sequences.

The cerebrospinal fluid examination revealed a slightly yellowish appearance with elevated total protein levels. Gradient echo T2*-weighted brain magnetic resonance imaging (MRI) demonstrated a rim of hypointense lesions surrounding the surface of the cerebellum, brainstem, frontal and temporal lobes, and thalamus, which was considered as hemosiderin depositions. From these MRI findings, she was diagnosed as having superficial siderosis of the central nervous system. Cerebral angiography revealed an aneurysm-like dilatation at the bifurcation of the right internal carotid-posterior communicating artery. (99m)Tc-ethyl cysteinate dimer single-photon emission computed tomography revealed hypoperfusion in the bilateral frontal and temporal lobes. Pelvic plain X-ray, pelvic computed tomography, and lumbosacral MRI revealed a sacral defect and an anterior sacral polycystic meningocele communicating with the spinal subarachnoid space. The patient's symptoms gradually worsened, and she died of septic shock because of pyelonephritis at the age of 77. An autopsy was performed; on pathological examination, we did not observe any findings associated with rupture of the aneurysm-like dilatation in the bifurcation of the right internal carotid-posterior communicating artery and cerebral amyloid angiopathy. Because duropathies-a new neurological disease concept-have been implicated as a cause of bleeding in the superficial siderosis, the anterior sacral polycystic meningocele, a type of duropathies, was presumed to be the most probable bleeding

    Chronic migraine is a disabling neurologic condition that affects 2% of the general population. Patients with chronic migraine have headaches on at least 15 days a month, with at least eight days a month on which their headaches and associated symptoms meet diagnostic criteria for migraine. Chronic migraine places an enormous burden on patients owing to frequent headaches; hypersensitivity to visual, auditory, and olfactory stimuli; nausea; and vomiting. It also affects society through direct and indirect medical costs. Chronic migraine typically develops after a slow increase in headache frequency over months to years. Several factors are associated with an increased risk of transforming to chronic migraine. The diagnosis requires a carefully performed patient interview and neurologic examination, sometimes combined with additional diagnostic tests, to differentiate chronic migraine from secondary headache disorders and other primary chronic headaches of long duration. Treatment takes a multifaceted approach that may include risk factor modification, avoidance of migraine triggers, drug and non-drug based prophylaxis, and abortive migraine treatment, the frequency of which is limited to avoid drug overuse. This article provides an overview of current knowledge regarding chronic migraine, including epidemiology, risk factors for its development, pathophysiology, diagnosis, management, and guidelines. The future of chronic migraine treatment and research is also discussed. PMID:24662044

    Background Although severe encephalopathy has been proposed as a possible contraindication to the use of noninvasive positive-pressure ventilation(NPPV),increasing clinical reports showed it was effective in patients with impaired consciousness and even coma secondary to acute respiratory failure,especially hypercapnic acute respiratory failure(HARF).To further evaluate the effectiveness and safety of NPPV for severe hypercapnic encephalopathy,a prospective case-control study was conducted at a university respiratory intensive care unit(RICU)in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)during the past 3 years.Methods Forty-three of 68 consecutive AECOPD patients requiring ventilatory support for HARF were divided into 2 groups,which were carefully matched for age,sex,COPD course,tobacco use and previous hospitalization history,according to the severity of encephalopathy,22 patients with Glasgow coma scale(GCS)0.05),but group A needed an average of 7 cmH2O higher of maximal pressure support during NPPV,and 4,4 and 7 days longer of NPPV time,RICU stay and hospital stay respectively than group B(P<0.05 or P<0.01).NPPV therapy failed in 12 patients(6 in each group)because of excessive airway secretions(7 patients),hemodynamic instability(2),worsening of dyspnea and deterioration of gas exchange(2),and gastric content aspiration(1).Conclusions Selected patients with severe hypercapnic encephalopathy secondary to HARF can be treated as effectively and safely with NPPV as awake patients with HARF due to AECOPD;a trial of NPPV should be instituted to reduce the need of endotracheal intubation in patients with severe hypercapnic encephalopathy who are otherwise good candidates for NPPV due to AECOPD.

  16. Percutaneous cannulated screw fixation of sacral fractures and sacroiliac joint disruptions with CT-controlled guidewires performed by interventionalists: Single center experience in treating posterior pelvic instability

    International Nuclear Information System (INIS)

    Highlights: • Minimally invasive sacroiliac screw fixation can be performed under CT-imaging. • Guidewires help in precise placement of cannulated sacroiliac screw. • Only a diminishing rate of misplacements can be seen. • The method appears to be a safe and very accurate procedure. - Abstract: Objective: The purpose of our study was to evaluate minimally invasive sacroiliac screw fixation for treatment of posterior pelvic instability with the help of CT controlled guidewires, assess its accuracy, safety and effectiveness, and discuss potential pitfalls. Methods: 100 guidewires and hollow titan screws were inserted in 38 patients (49.6 ± 19.5 years) suffering from 35 sacral fractures and/or 16 sacroiliac joint disruptions due to 33 (poly-)traumatic, 2 osteoporotic and 1 post-infectious conditions. The guidewire and screw positions were analyzed in multiplanar reconstructions. Results: The mean minimal distance between guidewire and adjacent neural foramina was 4.5 ± 2.01 mm, with a distinctly higher precision in S1 than S2. Eight guidewires showed cortical contacts, resulting in a total of 2% mismatched screws with subsequent wall violation. The fracture gaps were reduced from 3.6 ± 0.53 mm to 1.2 ± 0.54 mm. During follow-up 3 cases of minor iatrogenic sacral impaction (<5 mm) due to the bolting and 2 cases of screw loosening were observed. Interventional time was 84.0 min with a mean of 2.63 screws per patient whilst acquiring a mean of 93.7 interventional CT-images (DLP 336.7 mGy cm). Conclusions: The treatment of posterior pelvic instability with a guidewire-based screw insertion technique under CT-imaging results in a very high accuracy and efficacy with a low complication rate. Careful attention should be drawn to radiation levels

    2012-01-01

    Teratoma is the most common germ cell tumors in children. It is mostly located in sacrococcygeal region and has high malignant potential. Teratoma can be divided into mature type, immature type and malignant teratoma. Teratoma in sacral canal accounts for 0. 15% of intraspinal tumor with unknown pathogenesis. This article reported a case of teratoma and the case has developed several fistulas with jelly-like secretions. The development of fistulas causes adhesion of surrounding blood vessels and nerves as well as fibrosis, making the operation very difficult to perform. Residual tumor will lead to relapse and possible cancerization. So in order to prevent the development of fistulas and improve the patient's prognosis, timely diagnosis and operation are the most effective methods for teratoma in sacral canal.%畸胎瘤是儿童最常见的生殖细胞肿瘤,好发于骶尾部,具有恶性、潜能高的特点.可分为成熟型、未成熟型和恶性畸胎瘤.其中腰骶管内畸胎瘤约占椎管内肿瘤的0.15%,其发病机制尚不清楚.本病例为畸胎瘤,随着病情的发展在骶尾部和下腹部形成多处窦道,并有胶胨样分泌物流出.窦道的形成造成周围血管、神经粘连及纤维化,增加了手术难度,如有残留瘤组织易复发并有癌变的可能.为了防止窦道形成及癌变,提高患者预后,及时确诊并实施手术是治疗骶管内畸胎瘤最有效的方法.

  19. Peripheral injury of pelvic visceral sensory nerves alters GFRa (GDNF family receptor alpha localization in sensory and autonomic pathways of the sacral spinal cord

    Directory of Open Access Journals (Sweden)

    Shelley Lynne Forrest

    2015-04-01

    Full Text Available GDNF (glial cell line-derived neurotrophic factor, neurturin and artemin use their co-receptors (GFRα1, GFRα2 and GFRα3, respectively and the tyrosine kinase Ret for downstream signalling. In rodent dorsal root ganglia (DRG most of the unmyelinated and some myelinated sensory afferents express at least one GFRα. The adult function of these receptors is not completely elucidated but their activity after peripheral nerve injury can facilitate peripheral and central axonal regeneration, recovery of sensation, and sensory hypersensitivity that contributes to pain. Our previous immunohistochemical studies of spinal cord and sciatic nerve injuries in adult rodents have identified characteristic changes in GFRα1, GFRα2 or GFRα3 in central spinal cord axons of sensory neurons located in dorsal root ganglia. Here we extend and contrast this analysis by studying injuries of the pelvic and hypogastric nerves that contain the majority of sensory axons projecting to the pelvic viscera (e.g., bladder and lower bowel. At 7 d, we detected some effects of pelvic but not hypogastric nerve transection on the ipsilateral spinal cord. In sacral (L6-S1 cord ipsilateral to nerve injury, GFRα1-immunoreactivity (IR was increased in medial dorsal horn and CGRP-IR was decreased in lateral dorsal horn. Pelvic nerve injury also upregulated GFRα1- and GFRα3-IR terminals and GFRα1-IR neuronal cell bodies in the sacral parasympathetic nucleus that provides the spinal parasympathetic preganglionic output to the pelvic nerve. This evidence suggests peripheral axotomy has different effects on somatic and visceral sensory input to the spinal cord, and identifies sensory-autonomic interactions as a possible site of post-injury regulation.

    Pressure ulcers are chronic and difficult to heal. Pressure-reducing devices are clearly superior to a standard hospital mattress in preventing pressure ulcers, but only limited evidence and clinical intuition supports pressure-reducing devices in improving the healing rate of pressure ulcers. Local wound treatment should aim at maintaining a moist wound environment. The choice of a particular dressing depends on wound characteristics, such as the amount of exudate, dead space, or wound location. Nutritional status should be addressed as a process of good care. Debridement may improve time to a clean wound bed, but no clearly superior approach has been demonstrated. PMID:23571035

    Recent technological improvements have led to increasing clinical use of interface pressure mapping for seating pressure evaluation, which often requires repeated assessments. However, clinical conditions cannot be controlled as closely as research settings, thereby creating challenges to statistical analysis of data. A multistage longitudinal analysis and self-registration (LASR) technique is introduced that emphasizes real-time interface pressure image analysis in three dimensions. Suitable for use in clinical settings, LASR is composed of several modern statistical components, including a segmentation method. The robustness of our segmentation method is also shown. Application of LASR to analysis of data from neuromuscular electrical stimulation (NMES) experiments confirms that NMES improves static seating pressure distributions in the sacral-ischial region over time. Dynamic NMES also improves weight-shifting over time. These changes may reduce the risk of pressure ulcer development. PMID:18712638

    crompression due to sitting, lying or wearing brace in a heathy person results in discomfort and pain due to local isquemia. The normal protective pahtways are interrupted, however, in paraplegics, quadriplegic or the signals are ignored in severely de hibilitade, eldery or chronic ill patients. The pressure sore develops in these patients. Few papers have been done in Brazil abour pressure sores, despite economic problem envolved with. The purpose of this paper is to evaluate the epidemiology, treatment and complications of pressure sores in the Hospital das Clínicas (University of São Paulo from February 1997 to March 1999 in the Orthopedics Institute. A prospective study has been done. Data were evaluated as to the sex, age, sites, classification, type of treatment employed, length of stay and complications. The treatment was evaluated by the success rate and recurrence rate . The average follow-up period was 1 year and a half, ranging from 6 month to 2 years. 77 pressure sores in 45 patients were apraised. 36 men and 9 women, age range 17-64, mean 34,78 years. Of the patients, 100% had severe spinal cord injuries, and most of them victims of gun shot (60%. 93,3% of the wound were chronic (present longer than 3 months. 77,92% were treated by surgical procedures, and most of them with myocutaneous flaps (45%. The success rate changed with the site of the lesion: 80% trochanter, 84% sacrum and 66,6% ischium. The recurrence rate was 25%. The complication rate also changed with the site of the lesion: 84% trocanter, 64% sacrum and 50% isquium.

  11. Pelvic nerve injury causes a rapid decrease in expression of choline acetyltransferase and upregulation of c-Jun and ATF-3 in a distinct population of sacral preganglionic neurons

    Full Text Available Autonomic regulation of the urogenital organs is impaired by injuries sustained during pelvic surgery or compression of lumbosacral spinal nerves (e.g. cauda equina syndrome. To understand the impact of injury on both sympathetic and parasympathetic components of this nerve supply, we performed an experimental surgical and immunohistochemical study on adult male rats, where the structure of this complex part of the nervous system has been well defined. We performed unilateral transection of pelvic or hypogastric nerves and analysed relevant regions of lumbar and sacral spinal cord, up to four weeks after injury. Expression of c-Jun, the neuronal injury marker activating transcription factor-3 (ATF-3, and choline acetyltransferase (ChAT were examined. We found little evidence for chemical or structural changes in substantial numbers of functionally related but uninjured spinal neurons (e.g. in sacral preganglionic neurons after hypogastric nerve injury, failing to support the concept of compensatory events. The effects of injury were greatest in sacral cord, ipsilateral to pelvic nerve transection. Here, around half of all preganglionic neurons expressed c-Jun within one week of injury, and substantial ATF-3 expression also occurred, especially in neurons with complete loss of ChAT-immunoreactivity. There did not appear to be any death of retrogradely labelled neurons, in contrast to axotomy studies performed on other regions of spinal cord or sacral ventral root avulsion models. Each of the effects we observed occurred in only a subpopulation of preganglionic neurons at that spinal level, raising the possibility that distinct functional subgroups have different susceptibility to trauma-induced degeneration and potentially different regenerative abilities. Identification of the cellular basis of these differences may provide insights into organ-specific strategies for attenuating degeneration or promoting regeneration of these circuits after

    Recent clinical research has generated interest in the use of sacral wound dressings as preventive devices for patients at risk of ulceration. This study was conducted to identify the modes of action through which dressings can add to pressure ulcer prevention, for example, shear and friction force redistribution and pressure distribution. Bench testing was performed using nine commercially available dressings. The use of dressings can reduce the amplitude of shear stress and friction reaching the skin of patients at risk. They can also effectively redirect these forces to wider areas which minimises the mechanical loads upon skeletal prominences. Dressings can redistribute pressure based upon their effective Poisson ratio and larger deflection areas, providing greater load redistribution. PMID:23905962

    Blood pressure is the force of blood against artery walls. It is measured in millimeters of mercury (mm Hg and recorded as two numbers: systolic pressure (as the heart contracts over diastolic pressure (as the heart relaxes between beats. High blood pressure (hypertension is defined as chronically elevated high blood pressure, with systolic blood pressure (SBP of 140 mm Hg or greater, and diastolic blood pressure (DBP of 90 mm Hg or greater. High blood pressure (HBP, smoking, abnormal blood lipid levels, obesity and diabetes are risk factors for coronary heart disease, the leading cause of death in the US. Lifestyle modifications such as engaging in regular physical activity, quitting smoking and eating a healthy diet (limiting intake of saturated fat and sodium and increasing consumption of fiber, fruits and vegetables are advocated for the prevention, treatment, and control of HBP. As multiple factors influence blood pressure, the effects of each factor are typically modest, particularly in normotensive subjects, yet the combined effects can be substantial. Nutrition plays an important role in influencing blood pressure. Orange juice should be included as part of any low sodium diet and/or any blood pressure reducing eating plan, as it is sodium free, fat-free and can help meet recommended levels of potassium intake that may contribute to lower BP.

    Full Text Available Chronic urticaria (CU is a disturbing allergic condition of the skin. Although frequently benign, it may sometimes be a red flag sign of a serious internal disease. A multitude of etiologies have been implicated in the causation of CU, including physical, infective, vasculitic, psychological and idiopathic. An autoimmune basis of most of the ′idiopathic′ forms is now hypothesized. Histamine released from mast cells is the major effector in pathogenesis and it is clinically characterized by wheals that have a tendency to recur. Laboratory investigations aimed at a specific etiology are not always conclusive, though may be suggestive of an underlying condition. A clinical search for associated systemic disease is strongly advocated under appropriate circumstances. The mainstay of treatment remains H1 antihistaminics. These may be combined with complementary pharmacopeia in the form of H2 blockers, doxepin, nifedipine and leukotriene inhibitors. More radical therapy in the form of immunoglobulins, plasmapheresis and cyclophosphamide may be required for recalcitrant cases. Autologous transfusion and alternative remedies like acupuncture have prospects for future. A stepwise management results in favorable outcomes. An update on CU based on our experience with patients at a tertiary care centre is presented.

    Objective To investigate the influence of negative pressure wound therapy ( NPWT ) on vascular endothelial cells, proliferating cells and interleukin-6 variation in chronic wound. Methods Forty patients with chronic wound were divided into negative pressure wound therapy treatment group and conventional treatment group randomly. The granulation tissue formation was observed, and specimens were obtained from wound bed at 1, 4, 7, 14 days after treatment. The specimens were pathologically studied with hematoxylin-eosin staining to assess the wound healing process of the two groups. Furthermore, immunohistochemistry was done to estimate the number of vascular endothelial cells ( factor vm related antigen being used as marker ) and proliferating cells ( mouse anti-Ki-67 nuclear antigen being used as marker). Exudates of chronic wound were collected at 1, 4, 7, 14 days after negative pressure wound therapy treatment, interleukin-6 contents were determined and comparisons were made between them based on enzyme linked Immunosorbnent assay.Results The wounds of patients in negative pressure wound therapy treatment group were cured rapidly. The granulation tissue formation was promoted in negative pressure wound therapy treatment group. The number of vascular endothelial cells and proliferating cells in negative pressure wound therapy treatment group was larger than that of conventional treatment group ( P <0. 05 ). Interleukin-6 contents were decreased with time going after negative pressure wound therapy with significant variations between 1 ,4, 7 days ( P <0. 05 ), and levels of interleukin-6 were got close to normal at 7, 14days. Conclusion Compared with conventional treatment, negative pressure wound therapy could initiate granulation tissue formation more promptly, accelerate endothelial cell cytopoiesis, stimulate cell proliferation and decrease interleukin-6 contents.%目的 研究负压创面疗法对慢性创面血管内皮细胞、增

    2012-05-01

    Full Text Available Pressure sore is tissue ulceration due to unrelieved pressure, altered sensory perception, and exposure to moisture. Geriatric patients with organic problems and patients with spinal cord injuries are the high-risk groups. Soft tissues over bony prominences are the common sites for ulcer development. About 95% of pressure ulcers occur in the lower part of the body. Ischial tuberosity, greater trochanter, sacrum and heel are common sites. In addition to these, pressure sores at unusual sites like nasal alae, malar eminences, cervical region and medial side of knee have also been described. Only 1.6% of the patients present with sores in areas outside the pelvis and lower extremity. In a paraplegic patient, pressure sores are usually over extensor surface of knee and heel but pressure ulcer over popliteal fossa are extremely rare. We herein report a case of a 36-years-old diabetic and paraplegic male, who presented with multiple bed sores involving the sacral area, heels and bilateral popliteal fossa. Popliteal fossa is an unusual site for pressure sores. Only one similar case has been previously reported in the literature.

    Background Due to the quick rhythm of life and work pressure, more and more people suffer from sleep quality problems. In this study, we investigated the effect of electroacupuncture on sleep quality of chronic insomniacs and the safety of electroacupuncture therapy.Methods Four courses of electroacupuncture treatment were applied to 47 patients. With pre-treatment and post-treatment self-control statistical method, Pittsburgh sleep quality index (PSQI) scores were used for evaluating sleep quality. Polysomnogram was used for detecting insomniacs' changes in sleep architecture. The safety of electroacupuncture was evaluated by monitoring the self-designed adverse events and side effects during treatment and post-treatment.Results Electroacupuncture considerably improved insomniacs' sleep quality and social function during the daytime.Electroacupuncture had certain repairing effect on the disruption in sleep architecture. At the same time,electroacupuncture prolonged slow wave sleep (SWS) time and relatively rapid eye movement sleep (REM sleep) time.There was no hangover, addiction or decrements in vigilance during the daytime (incidence rate was 0). However,insomnia rebound rate was about 23% within one month.Conclusions These results suggest that electroacupuncture has beneficial effect on sleep quality improvement in the patients with chronic insomnia, which may be associated with repairing sleep architecture, reconstructing sleep continuity,as well as prolonging SWS time and REM sleep time. Electroacupuncture treatment for chronic insomnia is safe.Therefore, electroacupuncture therapy could be a promising avenue of treatment for chronic insomnia.

    Venous tortuosity is associated with multiple disease states and is often thought to be a consequence of venous hypertension and chronic venous disease. However, the underlying mechanisms of vein tortuosity are unclear. We hypothesized that increased pressure causes vein buckling that leads to a tortuous appearance. The specific aim of this study was to determine the critical buckling pressure of veins. We determined the buckling pressure of porcine jugular veins and measured the mechanical p...

    The function of the urinary bladder is partly controlled by parasympathetic preganglionic neurons (PPNs) of the sacral parasympathetic nucleus (SPN). Our recent work demonstrated that endomorphin-2 (EM-2)-immunoreactive (IR) terminals form synapses with μ-opioid receptor (MOR)-expressing PPNs in the rat SPN. Here, we examined the effects of EM-2 on excitatory synaptic transmission and the neuronal excitability of the PPNs in young rats (24-30 days old) using a whole-cell patch-clamp approach. PPNs were identified by retrograde labeling with the fluorescent tracer tetramethylrhodamine-dextran (TMR). EM-2 (3 μM) markedly decreased both the amplitude and the frequency of the spontaneous and miniature excitatory postsynaptic currents (sEPSCs and mEPSCs) of PPNs. EM-2 not only decreased the resting membrane potentials (RMPs) in 61.1% of the examined PPNs with half-maximal response at the concentration of 0.282 μM, but also increased the rheobase current and reduced the repetitive action potential firing of PPNs. Analysis of the current-voltage relationship revealed that the EM-2-induced current was reversed at -95 ± 2.5 mV and was suppressed by perfusion of the potassium channel blockers 4-aminopyridine (4-AP) or BaCl2 or by the addition of guanosine 5'-[β-thio]diphosphate trilithium salt (GDP-β-S) to the pipette solution, suggesting the involvement of the G-protein-coupled inwardly rectifying potassium (GIRK) channel. The above EM-2-invoked inhibitory effects were abolished by the MOR selective antagonist D-Phe-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2 (CTOP), indicating that the effects of EM-2 on PPNs were mediated by MOR via pre- and/or post-synaptic mechanisms. EM-2 activated pre- and post-synaptic MORs, inhibiting excitatory neurotransmitter release from the presynaptic terminals and decreasing the excitability of PPNs due to hyperpolarization of their membrane potentials, respectively. These inhibitory effects of EM-2 on PPNs at the spinal cord level may explain

    Multiple comorbidities and intensive therapy increase the risk of pressure ulcer (PU) development in critical care unit (CCU) patients. Given the high number of risk factors that CCU patients present with, it is important to acknowledge that not all PUs are entirely preventable, and incidence is thought to be between 14% and 42%. The consequences of acquiring a PU in critical care include increased mortality, morbidity and longer length of stay. Implementing prevention strategies as soon as the patient enters the unit can significantly reduce incidence. By adopting a proactive versus reactive mind-set, one CCU abandoned traditional PU risk assessment and implemented a number of intensive interventions, including the use of a prophylactic sacral dressing as an adjunct. As a result, PU incidence fell from 19.9 per 1000 patient population to 0.84 per 1000 patient population in 2014. In addition, 310 PU-free days were achieved. PMID:27345087

    Patients with traumatic spinal cord injury (TSCI) have an increased risk of developing pressure ulcers (PU). It is a retrospective study done by review of records in order to identify the characteristics of patients who were assisted at a tertiary hospital as well as the occurrence of PU. Most patients were male, white and 36,2% between 21 and 30 years. The most common causes of TSCI were wound by fire weapons followed by vehicle crash/overturn. There was a predominance of injury at the toracic level followed by cervical. The PU occurred in 20 pacientes (42,5%). The most frequent regions of occurrence were the sacral and heels. Only 25% of the records had PU's dimensions charted, 80% stated the aspect, and 52.1% did not state the stage. There is a need for better documentation of PU so that interventions used for treatment can be evaluated. PMID:16926993

    Medical device related pressure ulcers (MDR PUs) are defined as pressure injuries associated with the use of devices applied for diagnostic or therapeutic purposes wherein the PU that develops has the same configuration as the device. Many institutions have reduced the incidence of traditional PUs (sacral, buttock and heel) and therefore the significance of MDR PU has become more apparent. The highest risk of MDR PU has been reported to be patients with impaired sensory perception, such as neuropathy, and an impaired ability for the patient to communicate discomfort, for example, oral intubation, language barriers, unconsciousness or non-verbal state. Patients in critical care units typify the high-risk patient and they often require more devices for monitoring and therapeutic purposes. An expert panel met to review the evidence on the prevention of MDR PUs and arrived at these conclusions: (i) consider applying dressings that demonstrate pressure redistribution and absorb moisture from body areas in contact with medical devices, tubing and fixators, (ii) in addition to dressings applied beneath medical devices, continue to lift and/or move the medical device to examine the skin beneath it and reposition for pressure relief and (iii) when simple repositioning does not relieve pressure, it is important not to create more pressure by placing dressings beneath tight devices.

    Disclosed is a passive, in-situ pressure sensor. The sensor includes a sensing element having a ferromagnetic metal and a tension inducing mechanism coupled to the ferromagnetic metal. The tension inducing mechanism is operable to change a tensile stress upon the ferromagnetic metal based on a change in pressure in the sensing element. Changes in pressure are detected based on changes in the magnetic switching characteristics of the ferromagnetic metal when subjected to an alternating magnetic field caused by the change in the tensile stress. The sensing element is embeddable in a closed system for detecting pressure changes without the need for any penetrations of the system for power or data acquisition by detecting changes in the magnetic switching characteristics of the ferromagnetic metal caused by the tensile stress.

    Purpose: to investigate whether diffusion-weighted imaging (DWI) in magnetic resonance imaging (MRI) provides additional information about the periventricular white matter for the assessment of hydrocephalus. Materials and methods: sixteen MRI examinations (11 with acutely increased cerebral pressure, 5 without symptoms) on 15 patients with hydrocephalus (4 patients with communicating hydrocephalus and 11 patients with obstructive hydrocephalus) were analyzed. One symptomatic patient subsequently became asymptomatic. We investigated the ''apparent diffusion coefficient'' (ADC) in the subcortical and periventricular white matter. The ADCs of the study patients were compared with those of a healthy control group. Results: symptomatic patients with hydrocephalus, 6/11 showed periventricular edema and a significantly higher ADC values in the periventricular region than in the subcortical white matter. 5/11 symptomatic patients showed significantly higher ADC values even in the absence of periventricular interstitial edema (both groups contained patients with communicating and obstructive hydrocephalus). All 5 asymptomatic patients with hydrocephalus did not have a significantly higher ADC values in the periventricular region. Conclusion: in patients with hydrocephalus and acutely increased cerebral pressure, DWI showed a significantly higher ADC values in the periventricular region even without visible interstitial edema on conventional MRI sequences.

    Full Text Available Today, almost half of the patients who are on chronic kidney replacement therapy have diabetes. The enormous worldwide rise in these cases pose potential economic burden for every country and therefore monitoring kidney function should be a practice provided in outpatient settings. Poorly controlled diabetes will not only result in chronic renal failure, but also patients with chronic renal disease will have some metabolic abnormalities that will increase both morbidity and mortality of the patients. While hypertension may associate with most of the diabetic cases, those people with diabetes who have no rise in blood pressure will eventually develop hypertension at later stage of the chronic kidney disease.

    The basis for the new procedure is the simultaneous transcutaneous measurement of the peri-ulceral oxygen partial pressure (tcPO, using a minimum of 4 electrodes which are placed as close to the wound margin as possible, additionally, as a challenge the patient inhales pure oxygen for approximately 15 minutes. In order to evaluate the measurement data and to characterise the wounds, two new oxygen parameters were defined: (1 the oxygen characteristic (K-PO, and (2 the oxygen inhomogeneity (I-PO of a chronic wound. The first of these is the arithmetic mean of the two lowest tcPO measurement values, and the second is the variation coefficient of the four measurement values. Using the K-PO parameter, a grading of wound hypoxia can be obtained. To begin with, the physiologically regulated (and still compensated hypoxia with K-PO values of between 35 and 40 mmHg is distinguished from the pathological decompensated hypoxia with K-PO values of between 0 and 35 mmHg; the first of these still stimulates self-healing (within the limits of the oxygen balance. The decompensated hypoxia can be (arbitrarily divided into “simple” hypoxia (Grade I, intense hypoxia (Grade II and extreme hypoxia (Grade III, with the possibility of intermediate grades (I/II and II/III.Measurements were carried out using the new procedure on the skin of the right inner ankle of 21 healthy volunteers of various ages, and in 17 CVI (chronic venous insufficiency wounds. Sixteen of the 17 CVI wounds (i.e., 94% were found to be pathologically hypoxic, a state which was not found in any of the healthy volunteers. The oxygen inhomogeneity (I-PO of the individual chronic wounds increased exponentially as a function of the hypoxia grading (K-PO, with a 10-fold increase with extreme hypoxia in contrast to a constant value of approximately 14% in the healthy volunteers. This pronounced oxygen inhomogeneity explains inhomogeneous wound healings, resulting in the so

    In recent years sterilization that can cause problems of the psyche and marital life has been recommended much less frequently with respect to chronic diseases. As regards heart and hypertensive diseases pregnancy is always contraindicated in case of 3rd and 4th disease categories and sterilization is recommended according to the New York Heart Association. As far as 1st and 2nd category patients are concerned if the load carrying capacity is normal pregnancy could be undertaken. Combination pills are not recommended for contraception because they can cause fluid retention or increase the risk of thrombosis. If the patient has a higher-than-normal risk of developing thrombosis or infection, for instance, those who wear pacemakers only tablets containing progesterone or subdermal capsule implants can be used. In those with blood pressure problems the additional use of the IUD is also advised. Among diseases of neurological and psychic origin the effect of hormonal contraceptives is weakened by antiepileptics, but even in such cases older combination pills of larger doses of active ingredients can be employed. Migraine is exacerbated in 1/3 of patients; here IUDs can be used. Even the contraceptive tablets themselves can induce depression. In psychosis methods requiring regular attention can be easily forgotten, therefore the IUD is the most suitable device. In diabetes progesterone and other progestogens reduce insulin response, harm carbohydrate metabolism; therefore in young people the IUD is preferred an in older women with children even sterilization can be employed. Hormonal tablets must not be used in hyperlipidemia and liver diseases. Caution must be exercised in hyperthyroidism and in endocrine disorders (e.g., Cushing's syndrome); if it is accompanied by blood pressure disorders appropriate treatment is required. In kidney diseases pregnancy is contraindicated if it is accompanied by blood pressure increase or a higher level of creatine. On the other hand

    BACKGROUND: Smoking is a major risk factor for lung diseases and lower respiratory symptoms, but since not all smokers develop chronic bronchitis and since chronic bronchitis is also diagnosed in never-smokers, it has been suggested that some individuals are more susceptible to develop chronic...... bronchitis due to genetics. OBJECTIVE: To study the relative influence of genetic and environmental factors on the variation in the susceptibility to chronic bronchitis. METHODS: In a population-based questionnaire study of 13,649 twins, 50-71 years of age, from the Danish Twin Registry, we calculated sex......-specific concordance rates and heritability of chronic bronchitis. The response rate was 75%. RESULTS: The prevalence of chronic bronchitis was 9.3% among men and 8.5% among women. The concordance rate for chronic bronchitis was higher in monozygotic twins than in dizygotic twins among women; 0.30 vs. 0.17, but not...

    Thomas Torstensson

    Full Text Available To describe referred pain patterns provoked from intra-pelvic structures in women with chronic pelvic pain (CPP persisting after childbirth with the purpose to improve diagnostics and give implications for treatment.In this descriptive and comparative study 36 parous women with CPP were recruited from a physiotherapy department waiting list and by advertisements in newspapers. A control group of 29 parous women without CPP was consecutively assessed for eligibility from a midwifery surgery. Inclusion criterion for CPP was: moderate pain in the sacral region persisting at least six months after childbirth confirmed by pelvic pain provocation tests. Exclusion criteria in groups with and without CPP were: persistent back or pelvic pain with onset prior to pregnancy, previous back surgery and positive neurological signs. Pain was provoked by palpation of 13 predetermined intra-pelvic anatomical landmarks. The referred pain distribution was expressed in pain drawings and described in pain maps and calculated referred pain areas.Pain provoked by palpation of the posterior intra-pelvic landmarks was mostly referred to the sacral region and pain provoked by palpation of the ischial and pubic bones was mostly referred to the groin and pubic regions, with or without pain referred down the ipsilateral leg. The average pain distribution area provoked by palpation of all 13 anatomical landmarks was 30.3 mm² (19.2 to 53.7 in women with CPP as compared to 3.2 mm² (1.0 to 5.1 in women without CPP, p< 0.0001.Referred pain patterns provoked from intra-pelvic landmarks in women with CPP are consistent with sclerotomal sensory innervation. Magnification of referred pain patterns indicates allodynia and central sensitization. The results suggest that pain mapping can be used to evaluate and confirm the pain experience among women with CPP and contribute to diagnosis.

    Full Text Available Maria Vazquez Roque, Ernest P Bouras Gastroenterology and Hepatology Department, Mayo Clinic, Jacksonville, FL, USA Abstract: Constipation is a common functional gastrointestinal disorder, with prevalence in the general population of approximately 20%. In the elderly population the incidence of constipation is higher compared to the younger population, with elderly females suffering more often from severe constipation. Treatment options for chronic constipation (CC include stool softeners, fiber supplements, osmotic and stimulant laxatives, and the secretagogues lubiprostone and linaclotide. Understanding the underlying etiology of CC is necessary to determine the most appropriate therapeutic option. Therefore, it is important to distinguish from pelvic floor dysfunction (PFD, slow and normal transit constipation. Evaluation of a patient with CC includes basic blood work, rectal examination, and appropriate testing to evaluate for PFD and slow transit constipation when indicated. Pelvic floor rehabilitation or biofeedback is the treatment of choice for PFD, and its efficacy has been proven in clinical trials. Surgery is rarely indicated in CC and can only be considered in cases of slow transit constipation when PFD has been properly excluded. Other treatment options such as sacral nerve stimulation seem to be helpful in patients with urinary dysfunction. Botulinum toxin injection for PFD cannot be recommended at this time with the available evidence. CC in the elderly is common, and it has a significant impact on quality of life and the use of health care resources. In the elderly, it is imperative to identify the etiology of CC, and treatment should be based on the patient’s overall clinical status and capabilities.

    During hypoxia ATP degradation to uric acid is increased in animal models and humans. To assess the reliability of an overnight increase in uric acid excretion as a marker of nocturnal hypoxemia, we selected 10 normal volunteers (7 males and 3 females), 29 COPD patients (26 males and 3 females), and 49 subjects with obstructive sleep apnea (OSA) (43 males and 6 females). The patients underwent standard polysomnography, which was repeated in 14 subjects with nasal continuous positive airway pressure (CPAP), and were subdivided into two groups: Group D included desaturating subjects who spent at least 1 h at SaO2 < 90% and 15 min below 85%, and Group ND were nondesaturating subjects. The overnight change in the uric acid:creatinine ratio (delta UA:Cr) was negative in normal subjects (-27.5 +/- 9.1 [mean +/- SD]) and ND groups: -19.7 +/- 14.3 in COPD, -16.1 +/- 13.0 in OSA. In both COPD and OSA Group D, the ratio was usually positive: delta UA:Cr was 17.9 +/- 31.4 in Group D COPD (p < 0.001 versus ND) and 10.1 +/- 30.7 in Group D OSA (p < 0.001 versus ND and versus normal subjects) despite 4 of 15 false negative results in COPD and 8 of 20 in OSA. CPAP effective treatment induced a marked reduction ((p = 0.0024) in delta UA:Cr, leading to a negative value. We conclude that delta UA:Cr seems to be a promising index of significant nocturnal tissue hypoxia, with good specificity but poor sensitivity (about 30% false negative), which might be useful for the long-term follow-up of outpatients on nasal CPAP with a positive ratio at baseline.

    Otitis media occurs along a continuum. For example, otitis media with effusion characterized by fluid pathology can lead to chronic otitis media plus chronic mastoiditis, characterized by the presence of intractable tissue pathology such as cholesteatoma, cholesterol granuloma or granulation tissue. The literature defines chronic otitis media as having a tympanic membrane perforation and otorrhea. Amongst many other sequelae, which can result from the continuum, an important common one is chronic silent otitis media. This overlooked entity which includes pathology beneath an intact tympanic membrane is commonly seen in our human temporal bone laboratory and in patients. The clinical pathological correlates of this important disease are discussed herein. PMID:12021496

    Iodinated contrast (IC) is clinically used in diagnostic and interventional procedures, but its use can result in contrast-induced acute kidney injury (CI-AKI). Chronic kidney disease (CKD) and chronic hyperglycemia (CH) are important predisposing factors to CI-AKI. The aim of this study was to investigate the impact of iodinated contrast on the renal function and hemodynamics in rats with chronic hyperglycemia and chronic kidney disease. A total of 30 rats were divided into six groups; Sham: control of chronic renal disease; Citrate: control of chronic hyperglycemia (CH); Nx5/6: rats with 5/6 nephrectomy; Chronic Hyperglycemia: rats receiving Streptozotocin 65 mg/kg; Nx5/6 + IC: rats Nx5/6 received 6 mL/kg of IC; CH + IC: Chronic hyperglycemia rats receiving 6 mL/kg of IC. Renal function (inulin clearance; urinary neutrophil gelatinase-associated lipocalin, NGAL) and hemodynamics (arterial blood pressure; renal blood flow; renal vascular resistance) were evaluated. Iodinated contrast significantly increased urinary NGAL and reduced inulin clearance, while the hemodynamics parameters showed changes in arterial blood pressure, renal blood flow, and renal vascular resistance in both CKD and CH groups. The results suggest that the iodinated contrast in risk factors models has important impact on renal function and hemodynamics. NGAL was confirmed to play a role of highlight in diagnosis of CI-AKI.

    Deep tissue injury (DTI) can rapidly evolve into a higher stage pressure ulcer. Use of pressure-redistribution surfaces is a widely accepted practice for the prevention of pressure ulcers in acute care patients, particularly in departments where care processes limit mobility. A 15-year-old patient developed a sacral DTI 24 hours after completion of a lengthy (12- hour) electrophysiology (EP) study and catheter ablation. A root cause analysis (RCA) conducted to investigate the origin of the hospital-acquired suspected DTI prompted a small investigation to evaluate the pressure-distribution properties of the EP lab surface and an OR table pad. Five healthy adult employee volunteers were evaluated in the supine position by placing a sensing mat between the volunteer and the test surface. Interface pressures (on a scale of 0 mm Hg to 100 mm Hg) were captured after a "settling in" time of 4 minutes, and the number of sensors registering very high pressures (above 90 mm Hg) across the surface were recorded. On the OR table pad, zero to six sensors registered >90 mm Hg compared to two to 20 sensors on the EP lab surface. These data, combined with the acquired DTI, initiated a change in EP lab surfaces. Although interface pressure measurements only provide information about one potential support surface characteristic, it can be helpful during an RCA. Studies to compare the effect of support surfaces in all hospital units on patient outcomes are needed. PMID:23388397

    Pressure ulcers are complex chronic wounds for which no gold standard for prevention or treatment has yet been established. Several attempts at developing guidelines has been undertaken by different organizations. Pressure ulcers are devastating comorbidities for patients and difficult to prevent or manage. Whether or not pressure ulcers are preventable remains controversial. The strategy for prevention includes recognizing the risk, decreasing the effects of pressure, assessing nutritional status, avoiding excessive bed rest and prolonged sitting, and preserving the integrity of the skin. The principles of treatment of pressure ulcers include assessing severity, reducing pressure, friction and shear forces, optimizing local wound care, removing necrotic debris, managing bacterial contamination, and correcting nutritional deficits.

    Full Text Available Introduction. The prevalence of chronic diseases in adolescence is constantly increasing, especially in the last two decades. Adolescence is a period of important changes: body growth and development, sexual development, development of cognitive abilities, change in family relations and between peers, formation of personal identity and personal system of values, making decisions on future occupation etc. Chronic diseases in adolescence. Chronic disorders affect all development issues and represent an additional burden for adolescents. The interaction between chronic disorders and various development issues is complex and two-way: the disease may affect development, and development may affect the disease. Developmental, psychosocial and family factors are of great importance in the treatment of adolescents with chronic disorders. Chronic disorders affect all aspects of adolescent life, including relations with peers, school, nutrition, learning, traveling, entertainment, choice of occupation, plans for the future. Physicians should keep in mind that chronic diseases and their treatment represent only one aspect of person's life. Adolescents with chronic diseases have other needs as well, personal priorities, social roles and they expect these needs to be recognized and respected. Adolescent health care should be adjusted to the life style of adolescents.

    2016-01-01

    This article reports on the results of a Fairclough-inspired critical discourse analysis aiming to clarify how chronically ill patients are presented in contemporary Danish chronic care policies. Drawing on Fairclough’s three-dimensional framework for analyzing discourse, and using Dean’s concepts...... of governmentality as an interpretative lens, we analyzed and explained six policies published by the Danish Health and Medicines Authority between 2005 and 2013. The analysis revealed that discourses within the policy vision of chronic care consider chronically ill patients’ active role, lifestyle......, and health behavior to be the main factors influencing susceptibility to chronic diseases. We argue that this discursive construction naturalizes a division between people who can actively manage responsible self-care and those who cannot.

  16. [Chronic migraine: treatment].

    Science.gov (United States)

    Pascual, Julio

    2012-04-10

    We define chronic migraine as that clinical situation in which migraine attacks appear 15 or more days per month. Until recently, and in spite of its negative impact, patients with chronic migraine were excluded of the clinical trials. This manuscript revises the current treatment of chronic migraine. The first step should include the avoidance of potential precipitating/aggravating factors for chronic migraine, mainly analgesic overuse and the treatment of comorbid disorders, such as anxiety and depression. The symptomatic treatment should be based on the use of nonsteroidal anti-inflammatory agents and triptans (in this case ergotamine-containing medications. Preventive treatment includes a 'transitional' treatment with nonsteroidal anti-inflammatory agents or steroids, while preventive treatment exerts its actions. Even though those medications efficacious in episodic migraine prevention are used, the only drugs with demonstrated efficacy in the preventive treatment of chronic migraine are topiramate and pericranial infiltrations of Onabotulinumtoxin A.

  3. Chronic Rhinosinusitis with Nasal Polyps.

    Science.gov (United States)

    Stevens, Whitney W; Schleimer, Robert P; Kern, Robert C

    2016-01-01

    Chronic rhinosinusitis with nasal polyps (CRSwNP) is an important clinical entity diagnosed by the presence of both subjective and objective evidence of chronic sinonasal inflammation. Symptoms include anterior or posterior rhinorrhea, nasal congestion, hyposmia, and/or facial pressure or pain that last for a duration of more than 12 weeks. Nasal polyps are inflammatory lesions that project into the nasal airway, are typically bilateral, and originate from the ethmoid sinus. Males are more likely to be affected than females, but no specific genetic or environmental factors have been strongly linked to the development of this disorder to date. CRSwNP is frequently associated with asthma and allergic rhinitis, but the cellular and molecular mechanisms that contribute to the clinical symptoms are not fully understood. Defects in the sinonasal epithelial cell barrier, increased exposure to pathogenic and colonized bacteria, and dysregulation of the host immune system are all thought to play prominent roles in disease pathogenesis. Additional studies are needed to further explore the clinical and pathophysiological features of CRSwNP so that biomarkers can be identified and novel advances can be made to improve the treatment and management of this disease.

    Science.gov (United States)

    Stevens, Whitney W; Lee, Robert J; Schleimer, Robert P; Cohen, Noam A

    2015-12-01

    There are a variety of medical conditions associated with chronic sinonasal inflammation, including chronic rhinosinusitis (CRS) and cystic fibrosis. In particular, CRS can be divided into 2 major subgroups based on whether nasal polyps are present or absent. Unfortunately, clinical treatment strategies for patients with chronic sinonasal inflammation are limited, in part because the underlying mechanisms contributing to disease pathology are heterogeneous and not entirely known. It is hypothesized that alterations in mucociliary clearance, abnormalities in the sinonasal epithelial cell barrier, and tissue remodeling all contribute to the chronic inflammatory and tissue-deforming processes characteristic of CRS. Additionally, the host innate and adaptive immune responses are also significantly activated and might be involved in pathogenesis. Recent advancements in the understanding of CRS pathogenesis are highlighted in this review, with special focus placed on the roles of epithelial cells and the host immune response in patients with cystic fibrosis, CRS without nasal polyps, or CRS with nasal polyps.

    Lopes Roberto I

    2003-01-01

    Full Text Available Chronic penile strangulation is exceedingly rare with only 5 cases previously reported. We report an additional case of progressive penile lymphedema due to chronic intermittent strangulation caused by a rubber band applied to the penile base for 6 years. A 49-year-old man presented incapacity to exteriorize the glans penis. For erotic purposes, he had been using a rubber-enlarging band placed in the penile base for 6 years. With chronic use, he noticed that his penis swelled. Physical examination revealed lymphedema of the penis, phimosis and a stricture in the penile base. The patient was submitted to circumcision and the lymphedema remained stable 10 months postoperatively. Chronic penile incarceration usually causes penile lymphedema and urinary disturbance. Treatment consists of removal of foreign devices and surgical treatment of lymphedema.

    Directory of Open Access Journals (Sweden)

    Khadilkar Satish

    2011-01-01

    Full Text Available The spectrum of chronic dysimmune neuropathies has widened well beyond chronic demyelinating polyradiculoneuropathy (CIDP. Pure motor (multifocal motor neuropathy, sensorimotor with asymmetrical involvement (multifocal acquired demylinating sensory and motor neuropathy, exclusively distal sensory (distal acquired demyelinating sensory neuropathy and very proximal sensory (chronic immune sensory polyradiculopathy constitute the variants of CIDP. Correct diagnosis of these entities is of importance in terms of initiation of appropriate therapy as well as prognostication of these patients. The rates of detection of immune-mediated neuropathies with monoclonal cell proliferation (monoclonal gammopathy of unknown significance, multiple myeloma, etc. have been facilitated as better diagnostic tools such as serum immunofixation electrophoresis are being used more often. Immune neuropathies associated with malignancies and systemic vasculitic disorders are being defined further and treated early with better understanding of the disease processes. As this field of dysimmune neuropathies will evolve in the future, some of the curious aspects of the clinical presentations and response patterns to different immunosuppressants or immunomodulators will be further elucidated. This review also discusses representative case studies.

  8. Hypertension in Chronic Glomerulonephritis.

    Science.gov (United States)

    Ihm, Chun-Gyoo

    2015-12-01

    Chronic glomerulonephritis (GN), which includes focal segmental glomerulosclerosis and proliferative forms of GN such as IgA nephropathy, increases the risk of hypertension. Hypertension in chronic GN is primarily volume dependent, and this increase in blood volume is not related to the deterioration of renal function. Patients with chronic GN become salt sensitive as renal damage including arteriolosclerosis progresses and the consequent renal ischemia causes the stimulation of the intrarenal renin-angiotensin-aldosterone system(RAAS). Overactivity of the sympathetic nervous system also contributes to hypertension in chronic GN. According to the KDIGO guideline, the available evidence indicates that the target BP should be ≤140mmHg systolic and ≤90mmHg diastolic in chronic kidney disease patients without albuminuria. In most patients with an albumin excretion rate of ≥30mg/24 h (i.e., those with both micro-and macroalbuminuria), a lower target of ≤130mmHg systolic and ≤80mmHg diastolic is suggested. The use of agents that block the RAAS system is recommended or suggested in all patients with an albumin excretion rate of ≥30mg/ 24 h. The combination of a RAAS blockade with a calcium channel blocker and a diuretic may be effective in attaining the target BP, and in reducing the amount of urinary protein excretion in patients with chronic GN.

    Full Text Available BACKGROUND Chronic Heart Failure (CHF represents worldwide a clinical condition with increasing prevalence, high social, economical and epidemiological impact. Even if new pharmacological and non-pharmacological approachs have been recently used, mortality remains high in general population and quality of life is poor in these patients. DISCUSSION The association between CHF and sleep disorders is frequent but still undervalued: sleep apnoeas in CHF produce negative effects on cardiovascular system and an aggravation of prognosis. CPAP (Continuous Positive Airway Pressure is commonly used to treat sleep apnoeas in patients without cardiac involvement and it is also used in first line treatment of acute cardiogenic pulmonary oedema thanks to its hemodynamic and ventilatory effects. The addition of nightly CPAP to standard aggressive medical therapy in patients with CHF and sleep apnoeas reduces the number of apnoeas, reduces the blood pressure, and the respiratory and cardiac rate, reduces the activation of sympathetic nervous system, the left ventricular volume and the hospitalization rate; besides CPAP increases the left ventricular ejection fraction, amd the oxygenation, it improves quality of life, tolerance to exercise and seems to reduce mortality in patients with a higher apnoeas suppression. CONCLUSIONS These implications suggest to investigate sleep apnoeas in patients with CHF in order to consider a possible treatment with CPAP. Further studies need to be developed to confirm the use of CPAP in patients with CHF without sleep disorders.

    2016-02-01

    Spinal cord injury (SCI) leads generally to an irreversible loss of sensory functions and voluntary motor control below injury level. Cures that could repair SCI and/or restore voluntary walking have not been yet developed nor commercialized. Beyond the well-known loss of walking capabilities, most SCI patients experience also a plethora of motor problems and health concerns including specific bladder and bowel dysfunctions. Indeed, chronic constipation and urinary retention, two significant life-threatening complications, are typically found in patients suffering of traumatic (e.g., falls or car accidents) or non-traumatic SCI (e.g., multiple sclerosis, spinal tumors). Secondary health concerns associated with these dysfunctions include hemorrhoids, abdominal distention, altered visceral sensitivity, hydronephrosis, kidney failure, urinary tract infections, sepsis and, in some cases, cardiac arrest. Consequently, individuals with chronic SCI are forced to regularly seek emergency and critical care treatments when some of these conditions occur or become intolerable. Increasing evidence supports the existence of a novel experimental approach that may be capable of preventing the occurrence or severity of bladder and bowel problems. Indeed, recent findings in animal models of SCI have revealed that, despite paraplegia or tetraplegia, it remains possible to elicit episodes of micturition and defecation by acting pharmacologically or electrically upon specialized lumbosacral neuronal networks, namely the spinal or sacral micturition center (SMC) and lumbosacral defecation center (LDC). Daily activation of SMC and LDC neurons could potentially become, new classes of minimally invasive treatments (i.e., if orally active) against these dysfunctions and their many life-threatening complications.

    2012-01-01

    Full Text Available Chronic Daily Headache is a descriptive term that includes disorders with headaches on more days than not and affects 4% of the general population. The condition has a debilitating effect on individuals and society through direct cost to healthcare and indirectly to the economy in general. To successfully manage chronic daily headache syndromes it is important to exclude secondary causes with comprehensive history and relevant investigations; identify risk factors that predict its development and recognise its sub-types to appropriately manage the condition. Chronic migraine, chronic tension-type headache, new daily persistent headache and medication overuse headache accounts for the vast majority of chronic daily headaches. The scope of this article is to review the primary headache disorders. Secondary headaches are not discussed except medication overuse headache that often accompanies primary headache disorders. The article critically reviews the literature on the current understanding of daily headache disorders focusing in particular on recent developments in the treatment of frequent headaches.

  1. Management of chronic paronychia

    Directory of Open Access Journals (Sweden)

    Vineet Relhan

    2014-01-01

    Full Text Available Chronic paronychia is an inflammatory disorder of the nail folds of a toe or finger presenting as redness, tenderness, and swelling. It is recalcitrant dermatoses seen commonly in housewives and housemaids. It is a multifactorial inflammatory reaction of the proximal nail fold to irritants and allergens. Repeated bouts of inflammation lead to fibrosis of proximal nail fold with poor generation of cuticle, which in turn exposes the nail further to irritants and allergens. Thus, general preventive measures form cornerstone of the therapy. Though previously anti-fungals were the mainstay of therapy, topical steroid creams have been found to be more effective in the treatment of chronic paronychia. In recalcitrant cases, surgical treatment may be resorted to, which includes en bloc excision of the proximal nail fold or an eponychial marsupialization, with or without nail plate removal. Newer therapies and surgical modalities are being employed in the management of chronic paronychia. In this overview, we review recent epidemiological studies, present current thinking on the pathophysiology leading to chronic paronychia, discuss the challenges chronic paronychia presents, and recommend a commonsense approach to management.

  5. Lactoferrin in Chronic Pancreatitis

    Directory of Open Access Journals (Sweden)

    Full Text Available The present review is focused on the clinical significance of lactoferrin in pancreatic secretions and stone formation in chronic pancreatitis, and of serum anti-lactoferrin antibody in autoimmune pancreatitis. Lactoferrin secretion is increased in pancreatic secretions in calcified and non-calcified chronic pancreatitis. Lactoferrin, pancreatic stone protein and trypsin are present in pancreatic stones. We cannot conclude which protein is more important for the precipitate and stone formation. The presence of antilactoferrin antibody has been reported in serum in autoimmune diseases, such as autoimmune pancreatitis. The coincidental appearance of autoimmune pancreatitis with extrapancreatic autoimmune diseases strongly suggests a common autoimmune mechanism and lactoferrin is a candidate antigen. Lactoferrin may play an important role as a precipitate protein in pancreatic stone formation in chronic pancreatitis and as an autoantigen in autoimmune pancreatitis. Further studies are required to better understand the role of lactoferin.

    Tracheomalacia (TM) refers to loss of tracheal rigidity and resulting susceptibility to collapse. It is usually an incidental finding during investigations of other illness. The main symptoms are dyspnoea, cough, sputum production and hemoptysis. Most cases are considered as respiratory infection and are treated symptomatically. Acquired TM results from damage to trachea due to various conditions such as inflammation, chronic pressure, or medical/surgical procedures. The diagnosis is done by end-expiratory dynamic tracheal imaging, which demonstrates typical crescentric narrowing of trachea and reduced antero-posterior diameter cough suppressants or surgical measures like tracheoplasty, stenting or surgical repair. We are reporting a case of chronic cough, which was subsequently diagnosed as TM. PMID:26985425

    2005-01-01

    This review looks at the alterations in the systemic haemodynamics of patients with chronic liver disease (cirrhosis) in relation to essential hypertension and arterial hypertension of renal origin. Characteristic findings in patients with cirrhosis are vasodilatation with low overall systemic......, calcitonin gene-related peptide, nitric oxide, and other vasodilators, and is most pronounced in the splanchnic area. This provides an effective (although relative) counterbalance to raised arterial blood pressure. Subjects with arterial hypertension (essential, secondary) may become normotensive during the...... development of chronic liver disease, and arterial hypertension is rarely manifested in patients with cirrhosis, even in those with renovascular disease and high circulating renin activity. There is much dispute as to the understanding of homoeostatic regulation in cirrhotic patients with manifest arterial...

  8. Chronic urticaria: recent advances.

    Chronic urticaria is an umbrella term, which encompasses physical urticarias, chronic "idiopathic" urticaria and urticarial vasculitis. It is important to recognize patients with physical urticarias as the investigation and treatment differs in important ways from patients with idiopathic chronic urticaria or urticarial vasculitis. Although relatively uncommon, urticarial vasculitis is an important diagnosis to make and requires histological confirmation by biopsy. Underlying systemic disease and systemic involvement, especially of the kidneys, should be sought. It is now recognized that chronic "idiopathic" urticaria includes a subset with an autoimmune basis caused by circulating autoantibodies against the high affinity IgE receptor (FceR1) and less commonly against IgE. Although the autologous serum skin test has been proven useful in prompting search for and characterization of circulating wheal-producing factors in chronic urticaria, its specificity as a screening test for presence of functional anti-FceR1 is low, and confirmation by demonstration of histamine-releasing activity in the patient's serum must be the benchmark test in establishing this diagnosis. Improved screening tests are being sought; for example, ability of the chronic urticaria patient's serum to evoke expression of CD 203c on donor human basophils is showing some promise. The strong association between autoimmune thyroid disease and autoimmune urticaria is also an area of ongoing research. Drug treatment continues to be centered on the H1 antihistamines, and the newer second-generation compounds appear to be safe and effective even in off-label dosage. Use of systemic steroids should be confined to special circumstances such as tapering regimens for acute flare-ups. Use of leukotriene antagonists is becoming popular, but the evidence for efficacy is conflicting. Cyclosporin is also effective and can be used in selected cases of autoimmune urticaria, and it is also effective in non

    Enabled by emerging wearable sensors, telemedicine can potentially offer personalized medical services to long-term home care or remote clinics in the future, which can be particularly helpful in the management of chronic diseases. The wireless wearable pressure sensing system reported in this article provides an excellent example of such an innovation, whereby periodic or continuous monitoring of interface pressure can be obtained to guide routine compression therapy, the cornerstone of chronic venous disorder management. By applying a novel capacitive, iontronic sensing technology, a flexible, ultrathin, and highly sensitive pressure sensing array is seamlessly incorporated into compression garments for the monitoring of interface pressure. The linear pressure sensing array assesses pressure distribution along the limb in a real-time manner (up to a scanning rate of 5 kHz), and the measurement data can be processed and displayed on a mobile device locally, as well as transmitted through a Bluetooth communication module to a remote clinical service. The proposed interface pressure measuring system provides real-time interface pressure distribution data and can be utilized for both clinical and self-management of compression therapy, where both treatment efficacy and quality assurance can be ascertained.

    A detailed description is given of the complex pathological picture observed in the case of a worker with 30 years' occupational exposure to lead in an accumulator factory (evolution of the disease, clinical findings, autopsy). In spite of a typical clinical picture, lead is not held responsible for the terminal encephalopathy, in view of the fact that Alzheimer's syndrome was discovered at autopsy. However, the neurovegetative asthenia and progressive kidney disease without hypertonia, but with uraemia, which preceded the encephalopathy are in all probability due to chronic lead poisoning. The article discusses the diagnosis and symptomatology of chronic lead poisoning, encephalopathy and kidney disease.

    Full Text Available Abstract Background Postoperative epidural fibrosis may contribute to between 5% to 60% of the poor surgical outcomes following decompressive surgery. Correlations have been reported between epidural scarring and radicular pain, poor surgical outcomes, and a lack of any form of surgical treatment. The use of spinal endoscopic adhesiolysis in recent years in the management of chronic refractory low back and lower extremity pain has been described. Methods A prospective, randomized, double-blind trial was conducted to determine the outcome of spinal endoscopic adhesiolysis to reduce pain and improve function and psychological status in patients with chronic refractory low back and lower extremity pain. A total of 83 patients were evaluated, with 33 patients in Group I and 50 patients in Group II. Group I served as the control, with endoscopy into the sacral level without adhesiolysis, followed by injection of local anesthetic and steroid. Group II received spinal endoscopic adhesiolysis, followed by injection of local anesthetic and steroid. Results Among the 50 patients in the treatment group receiving spinal endoscopic adhesiolysis, significant improvement without adverse effects was shown in 80% at 3 months, 56% at 6 months, and 48% at 12 months. The control group showed improvement in 33% of the patients at one month and none thereafter. Based on the definition that less than 6 months of relief is considered short-term and longer than 6 months of relief is considered long-term, a significant number of patients obtained long-term relief with improvement in pain, functional status, and psychological status. Conclusion Spinal endoscopic adhesiolysis with targeted delivery of local anesthetic and steroid is an effective treatment in a significant number of patients with chronic low back and lower extremity pain without major adverse effects.

  20. Low chronic radiation doses

    International Nuclear Information System (INIS)

    In the context of the Chernobyl and Fukushima accidents where large territories have been contaminated durably and as consequence where local populations are submitted to chronic low radiation doses, IRSN (French institute for radiation protection and nuclear safety) has led various studies to assess the impact of chronic low doses. Studies about the effects of uranium on marine life show that the impact is strongly dependent on the initial state of the individual (zebra Danio rerio fish). The studies about the impact of chronic low doses due to cesium and strontium contamination show different bio-accumulations: 137Cs is found in the animal's whole body with higher concentrations in muscles and kidneys while 90Sr is found almost exclusively in bones and it accumulates more in female mice than in males. The study dedicated to the sanitary impact of chronic low doses on the workers of the nuclear industry shows a higher risk for developing a leukemia, a pleural cancer or a melanoma but no correlation appears between doses and the appearance of the pleural cancer or the melanoma.
