    The sacral region is one of the most vulnerable sites for the development of pressure sores. Even when surgical reconstruction is performed, there is a high chance of recurrence. Therefore, the concept of dual-dermal-barrier fashion flaps for sacral pressure sore reconstruction was proposed. From September 2007 to June 2010, nine patients with grade IV sacral pressures were enrolled. Four patients received bilateral myocutaneous V-Y flaps, four patients received bilateral fasciocutaneous V-Y flaps, and one patient received bilateral rotation-advanced flaps for sacral pressure reconstruction. The flaps were designed based on the perforators of the superior gluteal artery in one patient's reconstructive procedure. All flaps' designs were based on dual-dermal-barrier fashion. The mean follow-up time was 16 months (range = 12-25). No recurrence was noted. Only one patient had a complication of mild dehiscence at the middle suture line, occurring 2 weeks after the reconstructive surgery. The dual-dermal fashion flaps are easily duplicated and versatile. The study has shown minimal morbidity and a reasonable outcome.

    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

    Full Text Available Introduction: Pressure sores are the most common complication post spinal cord injury that requires patients to be on bed rest. Patient bed rest delay rehabilitation and may lead to other complications associated with immobility. This study sought to establish the treatment interventions physiotherapists provide to patients with sacral pressure sores and the factors that they consider when deciding whether the patient should receive physiotherapy in the ward or gym. Methods: This was a questionnaire based survey of physiotherapists working in spinal cord injury rehabilitation units in South Africa. The self-designed questionnaire was sent to all the main spinal rehabilitation units in the country (14 located in Gauteng, Kwa-Zulu Natal, Western Cape, Eastern Cape and Free State provinces. Results: Thirty-nine physiotherapists from a total of 51 completed the questionnaires (76% response rate. The most common treatment practice for patients with sacral pressure sores was bed rest (98%. The most common physio-therapy practices (70% included were upper limb muscle strengthening, upper and lower limb passive movements, positioning into prone and side lying and passive stretching. The choice of treatment environment was influenced by doctors’ orders and the size, grade and duration of the pressure sores. Conclusion: Direct involvement in pressure sore management in South Africa seem to be less than in other parts of the world. If we are to minimise the pressure sore impact, it appears like we need more focus on gait re-education and standardised ADL programmes and patient treatment in the gym to possibly maximise healing and rehabilitation.

  5. Chronic blood pressure control.

    Chronic blood pressure is maintained within very narrow limits around an average value. However, the multitude of physiologic processes that participate in blood pressure control present a bewildering array of possibilities to explain how such tight control of arterial pressure is achieved. Guyton and Coleman and colleagues addressed this challenge by creating a mathematical model that integrated the short- and long-term control systems for overall regulation of the circulation. The hub is the renal-body fluid feedback control system, which links cardiac function and vascular resistance and capacitance with fluid volume homeostasis as the foundation for chronic blood pressure control. The cornerstone of that system is renal sodium excretory capability, which is defined by the direct effect of blood pressure on urinary sodium excretion, that is, "pressure natriuresis." Steady-state blood pressure is the pressure at which pressure natriuresis balances sodium intake over time; therefore, renal sodium excretory capability is the set point for chronic blood pressure. However, this often is misinterpreted as dismissing, or minimizing, the importance of nonrenal mechanisms in chronic blood pressure control. This article explains the renal basis for the blood pressure set point by focusing on the absolute dependence of our survival on the maintenance of sodium balance. Two principal threats to sodium balance are discussed: (1) a change in sodium intake or renal excretory capability and (2) a change in blood pressure. In both instances, circulatory homeostasis is maintained because the sodium balance blood pressure set point is reached.

    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.

    In 2008, patients in the intensive care unit (ICU) at Danbury Hospital, Danbury, Connecticut, experienced 79 pressure ulcers. As a result, pressure ulcer-prevention interventions were standardized in critical care and medical-surgical units and education was provided to all direct patient care staff about principles of skin care and prevention. Following these efforts, 53 ICU patients developed pressure ulcers in the sacral area in fiscal year 2009, representing a 12.5% incidence for the ICU as compared to a 3.4% overall pressure ulcer incidence for the total hospital. In order to achieve additional reduction in pressure ulcer incidence, we replicated an initiative that called for application of a silicone foam dressing every 3 days to determine its effect on sacral pressure ulcer incidence in the ICU. We found that the use of the dressing further diminished the incidence of sacral pressure ulcers in our patients.

    Full Text Available Hydatid disease is caused by infection of Echinococcus granulosus. Bone hydatid cyst presentation without hepatic affectation is infrequent and occurs in 0,5-2% of cases. This rare condition makes clinicians not always aware of the disease, and as a result, misdiagnosis of spinal echinococcosis is common. We present a case of a 48-year-old female patient with primary sacral hydatidosis. Chronic low back pain radiating to the left buttock was the only symptom. The magnetic resonance imaging (MRI suggested a neurogenic tumor versus giant cell tumor. Biopsy and pathological study revealed a hydatid cyst. Anthelmintic and surgical treatment was performed. At 12 months after surgery, the patient is free of recurrence. In patients with chronic low back pain and a MR suggestive of neurogenic tumor, spinal hydatid cyst should be considered in the differential diagnosis. It is recommended the assistance of an anesthesiologist during biopsy to avoid an anaphylactic shock.

    The current concept of recruiting residual function of an inadequate pelvic organ by electrostimulation involves stimulation of the sacral spinal nerves at the level of the sacral canal. The rationale for applying SNS to fecal incontinence was based on clinical observations of its effect on bowel habits and anorectal continence function in urologic patients (increased anorectal angulation and anal canal closure pressure) and on anatomic considerations: dissection demonstrated a dual peripheral nerve supply of the striated pelvic floor muscles that govern these functions. Because the sacral spinal nerve site is the most distal common location of this dual nerve supply, stimulating here can elicit both functions. Since the first application of SNS in fecal incontinence in 1994, this technique has been improved, the patient selection process modified, and the spectrum of indications expanded. At present SNS has been applied in more than 1300 patients with fecal incontinence limited.

    Pressure sore rates remain high in both nursing homes as well as in hospitals. Numerous surgical options are available for defect coverage in the sacral region. However, objective data is scarce as to whether a specific flap design is superior to another. Here, we aim to compare two fasciocutaneous flap designs for sacral defect coverage: the gluteal rotation flap and the gluteal V-Y flap. All primary sacral pressure sores of grades III-IV that were being covered with gluteal fasciocutaneous rotational or V-Y flaps between January 2008 and December 2014 at our institution were analysed. A total of 41 patients received a total of 52 flaps. Of these, 18 patients received 20 gluteal rotational flaps, and 23 patients received 32 V-Y flaps. Both groups were comparable with regards to demographics, comorbidities and complications. Significantly more V-Y flaps were needed to cover smaller defects. Mean length of hospital stay was significantly prolonged when surgical revision had to be carried out. Both flap designs have proven safe and reliable for defect coverage after sacral pressure sores. Gluteal rotational flaps appear to be more useful for larger defects. Both flap designs facilitate their reuse in case of pressure sore recurrence. Complication rates appear to be comparable in both designs and to the current literature.

    Full Text Available Abstract Background Many devices are in use to prevent pressure ulcers, but from most little is known about their effects and costs. One such preventive device is the Australian Medical Sheepskin that has been proven effective in three randomized trials. In this study the costs and savings from the use of the Australian Medical Sheepskin were investigated from the perspective of a nursing home. Methods An economic model was developed in which monetary costs and monetary savings in respect of the sheepskin were balanced against each other. The model was applied to a fictional (Dutch nursing home with 100 beds for rehabilitation patients and a time horizon of one year. Input variables for the model consisted of investment costs for using the sheepskin (purchase and laundry, and savings through the prevented cases of pressure ulcers. The input values for the investment costs and for the effectiveness were empirically based on a trial with newly admitted rehabilitation patients from eight nursing homes. The input values for the costs of pressure ulcer treatment were estimated by means of four different approaches. Results Investment costs for using the Australian Medical Sheepskin were larger than the monetary savings obtained by preventing pressure ulcers. Use of the Australian Medical Sheepskin involves an additional cost of approximately €2 per patient per day. Preventing one case of a sacral pressure ulcer by means of the Australian Medical Sheepskin involves an investment of €2,974 when the sheepskin is given to all patients. When the sheepskin is selectively used for more critical patients only, the investment to prevent one case of sacral pressure ulcers decreases to €2,479 (pressure ulcer risk patients or €1,847 (ADL-severely impaired patients. The factors with the strongest influence on the balance are the frequency of changing the sheepskin and the costs of washing related to this. The economic model was hampered by considerable

    AIM:- To investigate the response of astrocytes and neurons in rat lumbo-sacral spinal cord and medulla oblongata induced by chronic colonic inflammation, and the relationship between them.METHODS: Thirty-three male Sprague-Dawley rats were randomly divided into two groups: experimental group (n = 17), colonic inflammation was induced by intra-luminal administration of trinitrobenzenesulfonic acid (TNBS);control group (n = 16), saline was administered intra-luminally.After 3, 7, 14, and 28 d of administration, the lumbo-sacral spinal cord and medulla oblongata were removed and processed for anti-glial fibrillary acidic protein (GFAP),Fos and GFAP/Fos immunohistochemistry.RESULTS: Activated astrocytes positive for GFAP were mainly distributed in the superficial laminae (laminae Ⅰ-Ⅱ)of dorsal horn, intermediolateral nucleus (laminae V),posterior commissural nucleus (laminae X) and anterolateral nucleus (laminae Ⅸ). Fos-IR (Fos-immunoreactive)neurons were mainly distributed in the deeper laminae of the spinal cord (laminae Ⅲ-Ⅳ, V-Ⅵ). In the medulla oblongata, both GFAP-IR astrocytes and Fos-IR neurons were mainly distributed in the medullary visceral zone (MVZ). The density of GFAP in the spinal cord of experimental rats was significantly higher after 3, 7, and 14 d of TNBS administration compared with the controls (50.4±16.8,29.2±6.5, 24.1±5.6, P<0.05). The density of GFAP in MVZ was significantly higher after 3 d of TNBS administration (34.3±2.5, P<0.05). After 28 d of TNBS administration,the density of GFAP in the spinal cord and MVZ decreased and became comparable to that of the controls (18.0±4.9,14.6±6.4, P>0.05).CONCLUSION: Astrocytes in spinal cord and medulla oblongata can be activated by colonic inflammation. The activated astrocytes are closely related to Fos-IR neurons.With the recovery of colonic inflammation, the activity of astrocytes in the spinal cord and medulla oblongata is reduced.

    Sacral agenesis is a central component in the spectrum of anomalies comprising the caudal regression syndrome. Sacral agenesis occurs more frequently in an infant born to mother of diabetes, rubella infection in first trimester than normal mothers. In a patient of sacral agenesis, it is important to recognize the neurologic deficit, neurogenic bladder dysfunction and other congenital anomalies. A case of partial sacral agenesis of 10 years old girl and another case of complete total agenesis associated with multiple anomalies in autopsied newborn are reported.

    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.

    The neuroanatomy and neurophysiology of the external urethral closure mechanisms still are under debate because the motor fibers that emanate from the sacral plexus and pudendal nerve to supply this segment have not been traced, nor has their functional interrelationship been established. Therefore, we dissected 3 male human cadavers (aged 31 to 69 years) by tracing the entire sacral plexus, particularly the pudendal nerve, from the cauda equina throughout the branching of the nerves to their final destination. The dissection demonstrated that the extrinsic urethral sphincter, formed by the rhabdosphincter around the membranous urethra as well as the levator ani muscle and pelvic floor (especially the transversus perinei muscle), is innervated by somatic nerve fibers that emanate primarily from sacral roots S2 and S3. In 5 patients with neurogenic lower urinary tract dysfunction electrostimulation of the sacral root and pudendal nerve markedly increased intraurethral closure pressures. Stimulation of the pudendal nerve or its transversus perinei branch alone resulted in an increase in intraurethral closure pressure to 60 to 70 cm. water--an increase similar to that produced by stimulation of the sacral root without neurotomy. By means of neurotomy and/or neural blockade with lidocaine we were able to differentiate between the contributions of each muscular element to the external sphincteric mechanism. Almost 70 per cent of the closure pressure of the external urethral sphincter is induced by stimulation of the S3 ventral root, while the other 30 per cent derives from S2 and S4 neuronal impulses.

    All components of the sacrum (bone, cartilage, bone marrow, meninges, nerves, notochord remnants, etc.) can give rise to benign or malignant tumours. Bone metastases and intraosseous sites of haematological malignancies, lymphoma and multiple myeloma are the most frequent aetiologies, while primary bone tumours and meningeal or nerve tumours are less common. Some histological types have a predilection for the sacrum, especially chordoma and giant cell tumour. Clinical signs are usually minor, and sacral tumours are often discovered in the context of nerve root or pelvic organ compression. The roles of conventional radiology, CT and MRI are described and compared with the histological features of the main tumours. The impact of imaging on treatment decisions and follow-up is also reviewed. (orig.)

    Objective To explore the clinical effects of various types Perforator Flap in the Reconstruction of Sacral Pressure Ulcers. Complications were analyzed. Methods A retrospective study from 100 operated cases using the superior gluteal artery perforator (SGAP) for sacral pressure ulcer is reported. According to defect parts and size, the patients are divided into two groups, which were designed with pure pedicle or island flaps respectively. Results The defect areas ranged from 4cmX5cm-10cmX12cm and 84 cases of 100 were healed primarily. We analyze two group's Complications and assess their risk factors. There is a statistical difference between the two groups. Conclusion The perforator flaps is an ideal method for the treatment of Ischia-sacral pressure ulcer. The pure pedicle flap operation is simple with low risk, but has low mobility, which is applicable to smaller defects. The island flap is a relatively complicated operation and has high mobility! The operation is applicable to ulcer bigger defect.%目的 探讨应用各种类型臀部穿支动脉皮瓣修复骶尾部褥疮的手术方法及临床效果.方法 对应用穿支皮瓣修复治疗骶尾部褥疮的100例病例按皮瓣类别分组进行分析.根据缺损部位及大小分为两组,分别设计单纯带蒂穿支皮瓣(旋转或移位皮瓣)、岛状穿支皮辨(推进或移位)修复骶尾部褥疮,并对其治愈率、并发症发生率和复发率等进行分析.结果 100例病例中84例皮瓣全部成活,伤口均一期愈合.随访1~7年,皮瓣质地优良,外形满意,溃疡无复发.结论 穿支蒂皮辩设计灵活,切取方便,血供可靠,不损伤臀部肌肉,供区无需植皮,是修复臀骶部褥疮的理想方法;旋转或移位皮瓣手术操作较简单,成功率高,但移动性差,仅适用于皮肤缺损小的褥疮;岛状皮瓣移动性高,操作相对复杂,手术风险大,适用于皮肤缺损较大或周围瘢痕较多的褥疮.

    Stress fractures of the sacrum during pregnancy or the postpartum seem uncommon. We report a new case of nontrauma-related postpartal sacral fracture. Only four similar cases have been reported to date. The patient was 36 years of age and her fracture was diagnosed four weeks after her first delivery. Vitamin D levels were low, but there was no osteomalacia. Other standard laboratory tests were normal, as were absorptiometry measurements at the lumbar spine and femur. Rheumatologists should consider sacral fracture in pregnant or nursing patients with buttock pain. Magnetic resonance imaging is the diagnostic investigation of choice.

    Tarlov or perineural cysts (TC) are commonly overlooked as a cause of sacral and ischial pain, and urogenital and bowel problems. TC can be seen on MRI, but are often considered asymptomatic. This is especially true for smaller cysts. Moreover, there are only few diagnostic characteristics that can be used to confirm that the cysts are the cause of the symptoms. As a consequence, a lot of controversy remains regarding the clinical importance of TC. Because of this underdiagnosed condition, patients often suffer for several years from unrecognized chronic neuropathic pain and neurological conditions. In this article, case reports of three patients with giant and smaller symptomatic sacral cysts are presented, in which electromyographic testing was performed to demonstrate nerve damage. We suggest that electromyography of the sacral nerve roots can be a reasonable tool for the diagnosis of symptomatic TC, as well as for the differentiation from other pathological entities causing sacral and ischial pain. Moreover, using electromyography it was also documented that smaller cysts of < 1 cm can cause nerve damage. Therefore incidence of symptomatic TC may be higher than initially thought.

    The chronic state of whiplash-associated disorder (WAD) might be understood as a somatization of existential pain. Intervention aimed to improve quality of life (QOL) seemed to be a solution for such situations. The basic idea behind the intervention was holistic, restoring quality of life and relationship with self, in order to diminish tension in the locomotion system, especially the neck. A psychosomatic theory for WAD is proposed. Our treatment was a short 2-day course with teachings in philosophy of life, followed by 6-10 individual sessions in gestalt psychotherapy and body therapy (Rosen therapy and Cranio Sacral therapy), followed by a 1-day course approximately 2 months later, closing the intervention. Two independent institutions did the intervention and the assessments. In a randomized, clinically controlled setting, 87 chronic WAD patients were included with a median duration of 37 months from their whiplash accidents. One patient never started. Forty-three had the above intervention (female/male = 36/7, ages 22-49, median 37 years) and another 43 were assigned to a nontreated control group (female/male = 35/8, ages 18-48, median 38). Six had disability pension and 27 had pending medicolegal issues in each group. Effect variables were pain in neck, arm, and/or head; measures of quality of life and daily activities; as well as general physical or mental health. Wilcoxon test for between-groups comparisons with intention-to-treat analyses was conducted; the square curve paradigm testing for immediate improvements of health and quality of life was also used. The groups were comparable at baseline. From the intervention group, 11 dropped out during the intervention (4 of those later joined the follow-up investigation), 22 of the remaining 32 graduated the course, and 35 of the 43 controls did as well. Approximately 3 months later, we found no clinically relevant or significant increase in any effect measure. The above version of a quality of life

  16. Is Lumbo-Sacral Angle Related to Plantar Loading Patterns in Patients with Ankylosing Spondylitis?

    2016-08-01

    Full Text Available Objective: Loss of lumbar lordosis is a clinical feature of ankylosing spondylitis (AS. Pedobarographic analysis assesses the interaction between the foot and the supporting surface. Postural abnormalities can reflect as pressure distribution deviations on pedobarography. The objective of the present study was to assess whether loss of lumbar lordosis detected with lumbo-sacral angle measurement is related to postural control assessed by plantar loading distribution in patients with AS. Materials and Methods: Thirty-two patients (two female, 30 male, mean age: 43.06±7.8 years with the diagnosis of AS, who already had a lateral lumbo-sacral X-ray performed within the past one year, were included in the study. Static and dynamic pedobarographic analyses of the patients were performed. The radiographic measurement of lumbo-sacral angle was done from lateral lumbo-sacral X-rays of the patients. Results: The static pedobarographic measurement revealed that lumbo-sacral angle was significantly correlated with forefoot plantar pressure (p=0.042; r=0.361. In the dynamic assessment, the maximum pressures were lower under the first metatarsal area in patients with lower lumbo-sacral angle (p=0.352; r=0.048. Conclusion: These findings suggest that foot joints may contribute to the compensation mechanism against the postural changes in patients with AS, statically and dynamically.

    Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion and are usually asymptomatic. 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.

    Objective To explore the effectiveness and security of temporary lead and tined lead in evaluation of sacral neuromodulation. Methods Thirty four cases with chronic voiding-defecation dysfunction, in which 4 cases were refractory urgent incontinence. 8 cases were refractory urinary urgency-frequency, 8 cases(6 cases with constipation) were chronic un-obstructive urinary retention, 4 cases were chronic pelvic pain syndrome or IC, 10 cases neurogenic bladder (3 and 7 cases resulted from spinal cord injury and Spina bifida respectively) . Temporary test electrodes and tined-lead were implanted into 16 and 18 cases respectively. And then the temporary stimulation tests were performed in a period of 5 ~ 14 days, recorded the daily times and volume of voiding and the related urodynamic parameters. And comparing the effectiveness of the two groups was performed. Results In patients with urgent incontinence and urinary urgency-frequency syndrome their improvements were 43 % and 35 % respectively. About 10% were cured completely. In chronic voiding-defecation dysfunction, there were 32.3 % and 38.2 % improvement respectively in temporary and tined lead group with significant difference. There were 23.7 % and 28.3 % improvement of IC respectively in temporary lead and tined lead group in the respects of volume voiding and pain amelioration. In temporary lead and tined lead group shifting of electrode position occurred in 4 cases and 1 case respectively. Conclusion Sacral neuromodulation is a secure, minimally invasive, effective method for chronic voiding dysfunction; tined lead electrode has the superiorities of minimally invasive, prevents the shift position of the electrode, and raised the effective rate.%目的 探讨骶神经调节测试评估阶段临时电极及自固定倒齿状电极(Tined Lead)的疗效及安全性.方法 34例慢性尿便功能障碍患者,其中难治性急迫性尿失禁4例,难治性尿频、尿急综合症8例,非梗阻性慢性尿潴留8

    The role of transitional vertebra in spondylolisthesis is still an enigma. Theoretically, obstruction of movements in the L5-S1 joint should provoke hypermobility at the L4-L5 vertebrae, thus leading to the development of spondylolisthesis. The aim of this study was to inquire whether a positive association exists between sacralization and spondylolisthesis. For this purpose, CT images of 436 consecutive patients were examined for the presence of sacralization and spondylolisthesis. The sample was divided into two groups: a sacralization group and non-sacralization group. Independent variables considered were age, sex and degree of lordosis. Sacralization was found in 13.1% of the individuals examined. It was found to be gender- and age-independent (P>0.05), Spondylolisthesis was identified in 7.3% of the individuals examined and found to be gender independent (P>0.05), and age dependent (Pspondylolisthesis was found. The mean lordosis angle in the spondylolisthesis group was 60.41° compared with 50.84° in patients without spondylolisthesis. No association was found between sacralization and the angle of lordosis (P>0.05). The current study did not reveal an association between sacralization and spondylolisthesis and as such sacralization should not be considered an etiology for the development of degenerative spondylolisthesis.

    Granville, Michelle; Jacobson, Robert E; Berti, Aldo

    2017-01-01

    Introduction In reviewing a larger group of osteoporotic vertebral compression fractures (VCFs), we found that the overall incidence of sacral insufficiency fractures (SIFs) is higher than commonly reported values. This is especially seen in patients with previous or concurrent lumbar VCFs and also in a subgroup that had lumbar stenosis or hip arthroplasty. The altered biomechanics due to associated lumbar stenosis or hip arthroplasty lead to increased mechanical stress on already weakened and deficient sacral alae, which are more vulnerable to osteoporotic weakening than other parts of the sacrum. Materials & methods We studied an overall population of patients with VCF seen clinically and separated the patients into the following groups: patients not previously treated, patients treated with vertebroplasty or kyphoplasty at one or more levels, and patients diagnosed with sacral fractures and treated with vertebroplasty or kyphoplasty. We wanted to see if a pattern existed among the patients who had sacral symptoms, were diagnosed with sacral insufficiency fractures, and subsequently underwent sacroplasty. Results In a review of 79 consecutive patients, over a 24-month period, with VCF who underwent surgical treatment, there were 10 patients who also had sacral insufficiency fractures. Four of the patients had sacral insufficiency fractures without VCF. None of the patients with sacral insufficiency fractures were on treatment for osteoporosis at the time of diagnosis. The following symptoms indicated SIF: lower sacral pain (n = 10), buttock pain (n = 7), lateral hip pain (n = 5), and groin pain radiating to the thigh (n = 4). The average time to diagnose SIF was two months after the onset of pain. Conclusions Sacral insufficiency fractures are a frequent cause of both acute and chronic pain; however, they are often missed by the majority of physicians. The frequency of undetected sacral fractures is high. This is due to a number of potential pitfalls

    Objective To investigate the therapeutic effect and safety of temporary electrode and Tined Lead electrode in Bacral neuromodulation evaluation. Methods Thirty-four patients with chronic pelvic floor dysfunction were divided into temporary electrode group (n = 16) and Tined Lead electrode group (n = 18), and temporary stimulation tests were performed after electrode placement. The conditions of voiding and defecation were recorded every day, and related urodynamic parameters were measured. Results The symptoms improved in 43% patients with urgent incontinence and 35% patients with urinary frequency and urgency, and 10% patients with urgent incontinence or urinary frequency and urgency were cured. There were significant differences in the rates of self-perceived improvement of voiding and defecation between temporary electrode group and Tined Lead electrode group (32.2% vs 38. 2% , P 0.0S) . Electrode shift took place in 4 patients in temporary electrode group and in 1 patient in Tined Lead electrode group. Conclusion Sacral neuromodulation is a safe, minimally invasive and effective method for treatment of chronic pelvic floor dysfunction, and Tined Lead electrode may prevent the electrode shift, increase the rate of success, and improve the therapeutic effect.%目的 探讨骶神经调节测试评估阶段临时电极及自固定例齿状( Tined Lead)电极的疗效及安全性.方法 将34例慢性盆底功能障碍患者按电极置入方法不同分为临时电极组(n=16)和自固定Tined Lead电极组(n=18),并进行术后两种电极临时刺激测试.在测试期记录排尿排便日记,进行相关尿动力学参数测定.结果 急迫性尿失禁患者中,有43%症状改善;尿频尿急患者中有35%症状改善;10%的急迫性尿失禁/尿频尿急患者治愈.临时电极组患者排尿排便自我感觉的改善率为32.2%,自固定Tined Lead电极组为38.2%,两组差异有统计学意义(P<0.05).盆底疼痛综合征/间质性膀胱

    Chronic rhinosinusitis may cause olfactory dysfunction and affects quality of life in patients. In a prospective study we investigated the effect of topical application of corticosteroids through pressure-pulsed inhalation as treatment option of chronic rhinosinusitis with olfactory disorder. Patients with sinonasal olfactory disorder according to the European Position Paper on Rhinosinusitis and Nasal Polyps (EP3OS) were allocated to the new nasal inhalation therapy or a systemic corticosteroid therapy, each receiving a corticosteroid course of 12 days. 18 patients received topical corticosteroid pressure-pulsed inhalation (AMSA, Schumacher, Dausenau) and 15 systemic corticosteroid. Olfactory function was measured before and after treatment using the Threshold Discrimination Identification score (TDI score) and visual analogue scales. Lund Mackay score (LMS) was measured before starting treatment. Olfactory function (OF) increased from 17.5 ± 6.4 to 21 ± 7.9 TDI points (p treatment after 2 months. In the follow-up period of 6 months, the mean TDI score dropped to 20.0 ± 9.2 points (p = 0.01). There was no correlation between LMS and TDI. Treatment of chronic rhinosinusitis with pressure-pulsed inhalation was demonstrated to be effective. Multicenter investigations with large participant numbers are needed.

    Full Text Available Introduction: Anatomy of the sacral hiatus is having clinical importance during caudal epidural block. Present study is aimed at determining anatomy of sacrum specially sacral hiatus for caudal epidural block, with the help of morphometric measurements of the sacrum in relation to sacral hiatus in dry sacral bones. Material & method: Total 103 complete and undamaged adult, dry sacral bones were measured with Vernier caliper (accuracy 0.1 mm and anatomical measurements were obtained. Results: Three bones were excluded because of total posterior closure defect. Agenesis of the sacral hiatus was detected in three sacral bones. Right and left superolateral sacral crests of the sacrum were taken as two points on dorsal surface of sacrum (forming the base of a triangle because posterior superior iliac spines impose on the superolateral sacral crests. The distance between the two superolateral sacral crests (base of a triangle, the distances between the right and left superolateral sacral crest and the sacral apex were on average 60.61(SD 6.71, 61.95 (11.71 and 61.4 (11.98 mm respectively.. Summary: An equilateral triangle formed between the apex of the sacral hiatus and right and left superolateral sacral crests.

    2017-02-01

    Lumbo-sacral (L5-S1) fusion is a widely performed procedure that has become the reference standard treatment for refractory low back pain. L5-S1 is a complex transition zone between the mobile lordotic distal lumbar spine and the fixed sacral region. The goal is to immobilise the lumbo-sacral junction in order to relieve pain originating from this site. Apart from achieving inter-vertebral fusion, the main challenge lies in the preoperative determination of the fixed L5-S1 position that will be optimal for the patient. Many lumbo-sacral fusion techniques are available. Stabilisation can be achieved using various methods. An anterior, posterior, or combined approach may be used. Recently developed minimally invasive techniques are gaining in popularity based on their good clinical outcomes and high fusion rates. The objective of this conference is to resolve the main issues faced by spinal surgeons in their everyday practice.

  8. Central Blood Pressure and Chronic Kidney Disease Progression

    2011-01-01

    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.)

    This study aims to describe and review a new method of uterine conservation in pelvic reconstruction for women with uterine prolapse. This is a prospective study of women who have undergone laparoscopic sacral suture hysteropexy. Structured questions, visual analogue patient satisfaction score (VAS), and vaginal examination were undertaken. Follow-up was performed by non-surgical reviewers. From July 2001 until August 2003, a total of 81 women underwent laparoscopic sacral suture hysteropexy for uterine prolapse. At a mean of 20.3 months follow-up, 76 women (93.8%) were available for questioning and 57 (70.3%) attended for examination. Sixty-five women (87.8%) had no symptoms of pelvic floor prolapse, 54 women (94.7%) had no objective evidence of uterine prolapse, and 61 women (82.4%) were satisfied with their surgery (VAS > or = 80%). Laparoscopic sacral suture hysteropexy attaches the posterior cervix to the sacral promontory via the right uterosacral ligament. Follow-up data of laparoscopic sacral suture hysteropexy indicate it to be an effective method in the management of uterine prolapse.

    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.

    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.

    Effectiveness of treatment with domiciliary nocturnal noninvasive positive pressure ventilation is analyzed in a group of patients with chronic alveolar hypoventilation of different etiologies. It was applied with two levels of pressure (BiPAP) via nasal mask. Criteria for evaluation were symptomatology and improvement in gas exchange. Data were analyzed by Student t tests. A total of 13 patients were included, mean age 55.7 range 20 to 76 years (5 male 8 female). Main diagnosis was tuberculosis in 6, four of them having had surgical procedure (thoracoplasty 2, frenicectomy 1 and neumonectomy 1), myopathy 3 (myasthenia gravis 1, muscular dystrophy 1 and diaphragmatic paralysis 1), obesity-hypoventilation syndrome 1, escoliosis 1, bronchiectasis 1 and cystic fibrosis 1. These last two patients were on waiting list for lung transplantation. At the moment of consultation, the symptoms were: dysnea 13/13 (100%), astenia 13/13 (100%), hypersomnolency 10/13 (77%), cephalea 9/13 (69%), leg edema 6/13 (46%), loss of memory 6/13 (46%). Regarding gas exchange, they showed hypoxemia and hypercapnia. Mean follow up was of 2.2 years (range 6 months to 4 years). Within the year, all 13 patients became less dyspneic. Astenia, hypersomnolency, cephalea, leg edema and memory loss disappeared. Improvement in gas exchange was: PaO2/FiO2 from 269 +/- 65.4 (basal) to 336.7 +/- 75.3 post-treatment (p = 0.0018). PaCO2 from 70.77 +/- 25.48 mmHg (basal) to 46.77 +/- 8.14 mmHg (p = 0.0013). Ventilatory support was discontinued en 5 patients: three because of pneumonia requiring intubation and conventional mechanical ventilation, two of them died and one is still with tracheostomy; One patient with bronchiectasis and one with cystic fibrosis were transplanted. The remaining eight patients are stable. In conclusion, chronic alveolar hypoventilation can be effectively treated with domiciliary nocturnal noninvasive ventilation.

    Evidence-based guidance for the use of airway clearance techniques (ACT) in chronic obstructive pulmonary disease (COPD) is lacking in-part because well-established measurements of pulmonary function such as the forced expiratory volume in 1s (FEV1) are relatively insensitive to ACT. The objective of this crossover study was to evaluate daily use of an oscillatory positive expiratory pressure (oPEP) device for 21-28 days in COPD patients who were self-identified as sputum-producers or non-sputum-producers. COPD volunteers provided written informed consent to daily oPEP use in a randomized crossover fashion. Participants completed baseline, crossover and study-end pulmonary function tests, St. George's Respiratory Questionnaire (SGRQ), Patient Evaluation Questionnaire (PEQ), Six-Minute Walk Test and (3)He magnetic resonance imaging (MRI) for the measurement of ventilation abnormalities using the ventilation defect percent (VDP). Fourteen COPD patients, self-identified as sputum-producers and 13 COPD-non-sputum-producers completed the study. Post-oPEP, the PEQ-ease-bringing-up-sputum was improved for sputum-producers (p = 0.005) and non-sputum-producers (p = 0.04), the magnitude of which was greater for sputum-producers (p = 0.03). There were significant post-oPEP improvements for sputum-producers only for FVC (p = 0.01), 6MWD (p = 0.04), SGRQ total score (p = 0.01) as well as PEQ-patient-global-assessment (p = 0.02). Clinically relevant post-oPEP improvements for PEQ-ease-bringing-up-sputum/PEQ-patient-global-assessment/SGRQ/VDP were observed in 8/7/9/6 of 14 sputum-producers and 2/0/3/3 of 13 non-sputum-producers. The post-oPEP change in (3)He MRI VDP was related to the change in PEQ-ease-bringing-up-sputum (r = 0.65, p = 0.0004) and FEV1 (r = -0.50, p = 0.009). In COPD patients with chronic sputum production, PEQ and SGRQ scores, FVC and 6MWD improved post-oPEP. FEV1 and PEQ-ease-bringing-up-sputum improvements were related to improved ventilation providing

    Purpose: To describe the findings of sacral meningeal cysts (SMCs) on MR myelography and assess its value for the diagnosis of SMCs. Material and Methods: We evaluated the MR images and MR myelograms obtained from 10 patients with SMC. MR myelograms were obtained using a 2D or 3D single-shot fast spin-echo sequence. In 5 patients, X-ray myelograms and postmyelographic CT images were compared with the MR myelograms. Results: A total of 33 SMCs were diagnosed within the spinal canal and/or sacral foramen. MR myelograms clearly revealed each cyst as a well-defined mass showing hyperintensity (10 cysts) or isointensity (23 cysts) compared to cerebrospinal fluid. MR myelograms demonstrated SMCs better than X-ray myelograms and postmyelographic CT images in 3 of the 5 patients. Conclusion: MR myelography can be an adjunct to conventional imaging techniques when surgical treatment is indicated, because it can precisely delineate the extent of SMCs. (orig.)

  18. Sacrality and worldmaking: new categorial perspectives

    Directory of Open Access Journals (Sweden)

    William E. Paden

    1999-01-01

    Full Text Available The category of the sacred in particular and the role of transcultural concept-formation in general have undergone an obvious crisis. For the most part, "the sacred," if not an empty label, has been linked with theologism, and transcultural concepts have been condemned for their general non-comparability and colonialist intent. The author approaches the matter of transcultural templates through an analysis of certain concepts of sacrality. With some exceptions, the discourse of sacrality has indeed been dominated by a single model, where "the sacred" became a reified noun—a substantive term for a supernatural reality, a label for the transcendent, or even an epithet for divinity, mystery, the wholly other. As such, the expression has functioned to bestow a sense of unity to the diversity of cultures, link that unity with a transcendent reality, and offer a simple way of making sense of otherwise foreign beliefs and practices by giving them a familiar, generic referent.

    Central pulse pressure can be non-invasively derived using the radial artery tonometric methods. Knowledge of central pressure profiles has predicted cardiovascular morbidity and mortality in several populations of patients, particularly those with known coronary artery disease and those receiving dialysis. Few data exist characterizing central pressure profiles in patients with mild-moderate chronic kidney disease who are not on dialysis. We measured central pulse pressure cross-sectionally in 2531 participants in the Chronic Renal Insufficiency Cohort study to determine correlates of the magnitude of central pulse pressure in the setting of chronic kidney disease. Tertiles of central pulse pressure (CPP) were 51 mmHg with an overall mean (± S.D.) of 46 ± 19 mmHg. Multivariable regression identified the following independent correlates of central pulse pressure: age, gender, diabetes mellitus, heart rate (negatively correlated), glycosylated hemoglobin, hemoglobin, glucose and PTH concentrations. Additional adjustment for brachial mean arterial pressure and brachial pulse pressure showed associations for age, gender, diabetes, weight and heart rate. Discrete intervals of brachial pulse pressure stratification showed substantial overlap within the associated central pulse pressure values. The large size of this unique chronic kidney disease cohort provides an ideal situation to study the role of brachial and central pressure measurements in kidney disease progression and cardiovascular disease incidence.

During the 1980's the needle method has been used for direct intraoperative pancreatic tissue fluid pressure measurements and later...... for percutaneous sonographically-guided pressure measurements. Clinical and experimental evaluation of the method showed comparable results at intraoperative and percutaneous measurements and little week-to-week variation. Furthermore, comparable pressures in duct and adjacent pancreatic tissue were found, i.......e. the needle pressure mirrors the intraductal pressure. Comparisons of pain registrations, morphological and functional parameters with pancreatic tissue fluid pressure measurements have revealed a relation between pressure and pain which probably is causal.

    Objective: A retrospective study to determine the success and complications of abdominal sacral colpopexy in correcting massive genital prolapse over an 8-year period between September 1989 and January 1997.Methods: The charts were reviewed for 3 patients with massive procidentia and 15 patients with symptomatic posthysterectomy vaginal vault prolapse, who desired preservation of sexual function and underwent abdominal sacral colpopexy with Marlex mesh at two community teaching hospitals.Results: In 16 of the 18 patients, one or more concurrent procedures were performed at the same time, including three Burch colpocystourethropexies and one Raz bladder neck suspension, which successfully controlled urinary stress incontinence. In three cases, staging procedures were done for ovarian neoplasia. There were no intraoperative complications. One patient developed a superficial abdominal wound infection, one patient had a deep venous thrombosis in her left leg 7 days postoperatively, and one patient experienced a 1 cm area of graft erosion 10 months postoperative requiring partial resection. Duration of follow-up has varied from 8 months to 5 years. One patient died 43 months after surgery of unrelated causes. No patients developed recurrent prolapse.Conclusions: Abdominal sacral colpopexy is a successful operation for the correction of prolapse. Serious complications are infrequent. Photographs of the technique and a review of the literature are presented.

    2002-03-01

    We evaluated the fractures of the lumbar and sacral vertebral limbus by disc impingement at the peripheral ring apophysis in 23 adults associated with trauma in 16 of them. Lumbalgia, radicular pain and narrow canal symptoms are the presenting forms of this underdiagnosed pathology. CT is the best method of examination, while plain roentgenograms and MR are usually negative. Accurate diagnosis and surgical technique with larger exposure are needed to resect the fractured fragments and protruded disc material for decompressing the roots and the dural sac. Our results were very good on the majority of cases.

    2016-01-01

    Sciatica may result from pathologies affecting the nerve both in its intraspinal and extraspinal course. In daily routine, the vast majority of cases are caused by herniation of the lumbar discs compressing the neural roots. Extraspinal causes of sciatic pain are usually underestimated and the imaging study may be completed after reporting the lumbar MRIs. However, early diagnosis of the exact etiology of sciatica is paramount for both relieving the symptoms and preventing any additional neurologic injury. In this pictorial assay, some relatively rare causes of sciatic neuralgia along the route of the sciatic nerve after leaving the sacral foramen will be displayed. PMID:27670092

    2015-01-01

    Full Text Available Sacral stress fractures are common in elderly people. However, sacral stress fracture should be always screened in the differential diagnoses of low back pain during the postpartum period. We present a case of sacral fracture in a thirty-six-year-old woman with low back pain and severe right buttock pain two days after cesarean section delivery of a 3.9 Kg baby. The diagnosis was confirmed by MRI and CT scan, while X-ray was unable to detect the fracture. Contribution of mechanical factors during the cesarean section is not a reasonable cause of sacral fracture. Pregnancy and lactation could be risk factors for sacral stress fracture even in atraumatic delivery such as cesarean section. Our patient had no risk factors for osteoporosis except for pregnancy and lactation. Transient or focal osteoporosis is challenging to assess and it cannot be ruled out even if serum test and mineral density are within the normal range.

    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

    2016-01-01

    Complex pressure ulcer wound sites often present with a wide scope of barriers to healing ranging from high colonization of multi-drug-resistant pathogens to tortuous internal anatomy which make the wound recalcitrant to traditional wound care including standard negative pressure wound therapy (NPWT). Negative pressure wound therapy with instillation (NPWTi-d) provides an opportunity to manage and heal wounds with indications not met by standard NPWT such as cavitating wounds with complex undermining and tunneling. In this clinical case report, a patient who presented with a chronic, non-healing Stage IV pressure ulcer underwent a tensor fascia lata flap reconstruction that was complicated by a partial flap-tip nonadherence with associated partial dehiscence of the flap incision that proved unresolvable until application of adjunctive NPWTi-d which allowed the wound to experience a robust rate of granulation, contraction, and closure.

    The intraocular pressures of a total of 286 eyes of patients with lepromatous and borderline lepromatous leprosy who never had regular ophthalmological care or local eye treatment were measured. The patients were categorised according to the type of leprosy they had, and the eyes were categorised as without or with chronic plastic iridocyclitis. In patients with lepromatous and borderline lepromatous types of leprosy the intraocular pressure was significantly lower in eyes with chronic plastic iridocylitis 10.1 (3.6) mmHg than in both unaffected eyes 11.0 (3.2) mmHg and control eyes 13.5 (2.5) mmHg. It has been shown that chronic plastic iridocyclitis which remains untreated for years results in a lower intraocular pressure than normal.

    2013-07-31

    Mosaic trisomy 13 occurs when there is a percentage of trisomic cells for an entire chromosome 13, while the remaining percentage of cells is euploid. The prevalence of this syndrome ranges from 1 in 10 000 to 1 in 20 000 births. Complete, partial or mosaic forms of this disorder can occur. The phenotype of mosaic trisomy 13 patients varies widely. Patients with mosaic trisomy 13 usually have a longer survival and a less severe phenotype compared to patients with complete trisomy 13. Genetic counselling is difficult due to the wide variation among the clinical manifestations of these patients. There have been 49 cases of mosaic trisomy 13 reported in the literature. We report the case of a patient with mosaic trisomy 13, a sacral appendage and a cleft lip and palate.

    We present a case of an atypical recurrent meningioma of the sacrum with pulmonary metastasis in a 31-year-old man. He presented with deep-seated buttock pain and urinary hesitancy for 3 months. MRI revealed a lesion occupying the central and left side of the sacral canal at the S1-S2 level. Surgical excision of the lesion via a posterior approach was undertaken, and the patient became symptom-free post-operatively. Histology confirmed atypical meningioma. Eight months later he re-presented with similar symptoms, and MRI confirmed local recurrence. The patient underwent left hemisacrectomy. Six months later he again presented with low back pain and MRI confirmed a second local recurrence. A CT scan of the chest showed multiple lung metastases. The patient died of a severe chest infection 18 months later. (orig.)

    Sacral neuromodulation (SNM) represents a promising option for managing treatment-refractory neurogenic bladder dysfunction. It remains to be seen, however, which types of neurogenic bladder dysfunction and which underlying neurological disorders best respond to SNM. Constant improvements in SNM have been achieved and it is now a minimally invasive approach performed under local anesthesia which should be considered before undertaking larger reconstructive procedures. An electrode is implanted in the S3 or S4 sacral foramen and during a test phase lasting for days to weeks the patient keeps a bladder diary to determine whether SNM has provided a relevant benefit. If the results of the test phase are positive, a neuromodulator is implanted in the gluteal area (or more rarely in the abdominal wall).The mechanism of action of SNM has not been completely clarified, but the afferent nerves most likely play a key role. It appears that SNM produces a modulation of medullary reflexes and brain centers by peripheral afferents. The implanted neuromodulation system does not lead to limitation of the patient's activities. However, it should be noted that high-frequency diathermy and unipolar electrocauterization are contraindicated in patients with neuromodulators, that during extracorporeal shock wave lithotripsy the focal point should not be in the direct vicinity of the neuromodulator or the electrode, that ultrasound and radiotherapy in the region of the implanted components should be avoided, that the neuromodulation should be discontinued in pregnancy, and that MRI examinations should only be conducted when urgently indicated and the neuromodulator is turned off.

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

    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.

    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.

    Groups of 16 female Long-Evans rats received 0, 1, 2.5, 5, 10, 25, and 50 mg cadmium/liter dringking water (parts per million (ppm)), from the time they were weaned until they were 30 mo old. Systolic pressure was measured indirectly in triplicate at 6-mo intervals. Both 2.5 and 5 ppm cadmium consistently induced significant elevations in mean systolic pressure, ranging from 13 to 33 mmHg. At 6 mo, 10 and 25 ppm cadmium also induced significant elevations, whereas at 12 mo and subsequently 1 ppm cadmium induced significant elevations. With 10 ppm cadmium or less weight gain was normal and there was no evidence of cadmium toxicity. With 25 and 50 ppm cadmium weight gain was diminished, suggesting toxicity. Five rats with each level of exposure were sacrificed every 6 mo from a second population of similarly handled rats in order to determine renal cadmium concetrations. Cadmium intakes that had induced hypertension were associated with mean renal cadmium concentrations ranging from 5 to 50 mug/g kidney.

    AIM: To investigate whether there was a dominant sacral root for the motive function of rectum and anal sphincter,and to provide an experimental basis for sacral root electrically stimulated defecation in spinal cord injuries.METHODS: Eleven spinal cord injured mongrel dogs were included in the study. After L4-L7 laminectomy, the bilateral L7-S3 roots were electrostimulated separately and rectal and sphincter pressure were recorded synchronously. Four animals were implanted electrodes on bilateral S2 roots.RESULTS: For rectal motorial innervation, S2 was the most dominant (mean 15.2 kPa, 37.7% of total pressure),S1 (11.3kPa, 27.6%) and S3 (10.9 kPa, 26.7%) contributed to a smaller part. For external anal sphincter, S3 (mean 17.2 kPa, 33.7%) was the most dominant, S2 (16.2 kPa,31.6%) and S1 (14.3 kPa, 27.9%) contributed to a lesser but still a significant part. Above 85% L7 roots provided some functional contribution to rectum and anal sphincter.For both rectum and sphincter, the dght sacral roots provided more contribution than the left roots. Postoperatively, the 4 dogs had electrically stimulated defecation and micturition under the control of the neuroprosthetic device.CONCLUSION: S2 root is the most dominant contributor to rectal pressure in dogs. Stimulation of bilateral S2 with implanted electrodes contributes to good micturition and defecation in dogs.

    This is the first report of a case of sacral radicular cysts in a patient with autosomal dominant polycystic kidney disease (ADPKD). A 46-year-old woman with ADPKD was found to have bilateral sacral radicular cysts discovered incidentally by magnetic resonance imaging (MRI). Cysts arising from arachnoid or spinal meningeal sac should be considered one of the manifestations of a more widespread connective tissue disorder associated with ADPKD.

    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.

    2006-10-01

    Full Text Available Abstract Background Developmental dysplasia of the hip (DDH is a condition in which bone growth irregularities subject articular cartilage to higher mechanical stresses, increase susceptibility to subluxation, and elevate the risk of early osteoarthritis. Study objectives were to calculate three-dimensional cartilage contact stresses and to examine increases of accumulated pressure exposure over a gait cycle that may initiate the osteoarthritic process in the human hip, in the absence of trauma or surgical intervention. Methods Patient-specific, non-linear, contact finite element models, constructed from computed tomography arthrograms using a custom-built meshing program, were subjected to normal gait cycle loads. Results Peak contact pressures for dysplastic and asymptomatic hips ranged from 3.56 – 9.88 MPa. Spatially discriminatory cumulative contact pressures ranged from 2.45 – 6.62 MPa per gait cycle. Chronic over-pressure doses, for 2 million cycles per year over 20 years, ranged from 0.463 – 5.85 MPa-years using a 2-MPa damage threshold. Conclusion There were significant differences between the normal control and the asymptomatic hips, and a trend towards significance between the asymptomatic and symptomatic hips of patients afflicted with developmental dysplasia of the hip. The magnitudes of peak cumulative contact pressure differed between apposed articular surfaces. Bone irregularities caused localized pressure elevations and an upward trend between chronic over-pressure exposure and increasing Severin classification.

    Home-based stroke hemiplegia patients tend to fall easily. Poor toe clearance is reported to be one of the causes of falling, although there are many other related factors. We developed a low-priced insole type portable foot pressure measurement device, and measured the foot pressure distribution and the foot pressure-time curve of 20 chronic hemiplegia patients and compared them with 36 healthy controls. We also analyzed the outdoor gait of a chronic hemiplegia patient on flat ground, on rough terrain, walking up stairs and on a downward slope. The result was that the load rate of the unaffected heel was significantly increased in hemiplegic gait, and there was a significant negative correlation between the affected side stance phase rate and gait time for 10 m distance (r = -0.73, P hemiplegia patients tend to be highly dependent on their unaffected side during indoor and outdoor gait.

  10. A rapid decrease in pulmonary arterial pressure by noninvasive positive pressure ventilation in a patient with chronic obstructive pulmonary disease

    2007-01-01

    Full Text Available The natural history of chronic obstructive pulmonary disease (COPD is characterized by progressive decrements in expiratory airflow, increments in end-expired pulmonary volume, hypoxaemia, hypercapnia and the progression of pulmonary arterial hypertension (PAH. Noninvasive positive pressure ventilation (NPPV treatment is increasingly used for the treatment of acute and chronic respiratory failure in patients with COPD. NPPV can increase PaO2 and decrease PaCO2 by correcting the gas exchange in such patients. The acute effect of NPPV on decreasing PAP is seen in patients with respiratory failure, probably due to the effect on cardiac output. Here, a case with COPD whose respiratory acidosis and PAH rapidly improved by NPPV was presented and therefore we suggested to perform an echocardiographic assessment to reveal an improvement of PAH as well as respiratory acidosis, hypercapnia and hypoxemia with that treatment.

    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...... pressures in the two groups were 140 (110-200) and 133 (110-165), in the high and low enalaprilat concentration groups, respectively, and after 3 months they were 135 (105-170) and 130 (105-170) mmHg (NS). Median diastolic blood pressure was 80 mmHg in each group both at baseline (65-100) and at follow......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...

    The authors previously reported that the visit-to-visit variability of blood pressure is correlated with renal function decline in nondiabetic chronic kidney disease. Little is known about the association between visit-to-visit variability and renal function decline in patients with diabetic chronic kidney disease. The authors retrospectively studied 69 patients with diabetic chronic kidney disease stage 3a, 3b, or 4. The standard deviation and coefficient of variation of blood pressure in 12 consecutive visits were defined as visit-to-visit variability of blood pressure. The median observation period was 32 months. In univariate correlation, the standard deviation and coefficient of variation of blood pressure were not significantly associated with the slope of estimated glomerular filtration rate. There was no significant association between the visit-to-visit variability of blood pressure and renal function decline in patients with diabetic chronic kidney disease, in contrast with our previous study of nondiabetic patients with chronic kidney disease.

  13. 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.

  15. 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.

    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.

    In this report, we describe the feasibility of locating the sacral plexus nerve using a parasacral approach and an ultrasound-guided technique. The parasacral region using a curved probe (2-5 MHz) was scanned in 17 patients in search of the medial border of the ischial bone and the lateral border of the sacrum, which represent the limit of the greater sciatic foramen. In addition, attempts were made to identify the piriformis muscles and the gluteal arteries. The sacral plexus was identified at the level of the sciatic foramen as a round hyperechoic structure. The gluteal arteries were identified in 10 of 17 patients, but we failed to positively identify the piriformis muscle in any patient. To confirm localization of the sacral plexus, an insulated needle attached to a nerve stimulator was advanced and, in each case, a sacral plexus motor response was elicited (plantar flexion-12, dorsal flexion-1, hamstring muscle stimulation-3, gastrocnemius muscle stimulation-1-not recorded) at a current between 0.2 and 0.5 mA. No complications were observed. This report confirms the feasibility of using ultrasound to locate the sacral plexus using a parasacral approach.

    Full Text Available Objective: BIONs™ (BIOnic Neurons are injectable, wireless microstimulators that make chronic BION Active Seating (BAS possible for pressure ulcer prevention (PUP. Neuromuscular electrical stimulation (NMES produces skeletal motion and activates trophic factors, counteracting three major etiological mechanisms leading to pressure ulcers (PUs: immobility, soft-tissue atrophy, and ischemia. Companion papers I and II reviewed prior experience with NMES for PUP, and analyzed the biomechanical considerations, respectively. This paper presents a treatment strategy derived from this analysis, and the clinical results of the first three cases.

    1. Sacral parasympathetic preganglionic neurones were identified by intracellular and extracellular micro-electrode recording of antidromic potentials in response to stimulation of the pelvic nerve or the second or third sacral ventral roots.2. The segmental distribution of autonomic neurones varied in different cats. In some cats they were mainly in S2 segment, in others in S3 and in the remainder, in both S2 and S3.3. The antidromic potentials showed initial segment-somadendritic (IS-SD) inflexions and delayed depolarizations and were slightly less prolonged than those of sympathetic neurones but more prolonged than those of spinal motoneurones. After-hyperpolarization was observed after the antidromic spike potential.4. The conduction velocities for sacral parasympathetic preganglionic fibres were less than 12.5 m/sec and thus were similar to those of sympathetic preganglionic fibres.5. Parasympathetic neurones were not excited by micro-electro-phoretically applied 5-hydroxytryptamine, noradrenaline or acetylcholine.

    Results: The indices like sacral index, curvature index, corpobasal index and alar Index were found to be statistically significant with p value 0.05 and was statistically not significant. Conclusions: The most useful aspect of such studies was to determine appropriate indices of sexual dimorphism for sacral bone. The study concluded that no single index can identify sex of sacrum with 100% accuracy. So multiple indices should be used for determination of sex by sacrum with 100% accuracy.

    Full Text Available In most cases, sacral neuromodulation is used as a treatment for urge incontinence and symptoms of urgency and frequency. It is most used in those who are refractory to traditional management. It is much less common to be used for bladder atony. In this report, we present a case of a 24-year-old woman with a history of urinary retention and bladder atony who failed medical management and subsequently had an InterStim sacral neuromodulator implanted. After implantation, she was able to discontinue intermittent catheterization and had a decrease in her postvoid residual from 848 to 72 mL.

    The wireless implantable/intracavity micromanometer (WIMM) system was designed to fulfill the unmet need for a chronic bladder pressure sensing device in urological fields such as urodynamics for diagnosis and neuromodulation for bladder control. Neuromodulation in particular would benefit from a wireless bladder pressure sensor which could provide real-time pressure feedback to an implanted stimulator, resulting in greater bladder capacity while using less power. The WIMM uses custom integrated circuitry, a MEMS transducer, and a wireless antenna to transmit pressure telemetry at a rate of 10 Hz. Aggressive power management techniques yield an average current draw of 9 μA from a 3.6-Volt micro-battery, which minimizes the implant size. Automatic pressure offset cancellation circuits maximize the sensing dynamic range to account for drifting pressure offset due to environmental factors, and a custom telemetry protocol allows transmission with minimum overhead. Wireless operation of the WIMM has demonstrated that the external receiver can receive the telemetry packets, and the low power consumption allows for at least 24 hours of operation with a 4-hour wireless recharge session.

    2011-01-01

    Full Text Available We report an unusual and complex case of spinal trauma in a 17-year-old boy who presented with a transverse sacral fracture associated with multiple-level lumbar fractures, paraparesis, and bladder involvement. A two-stage surgery was performed. The lumbar spine fractures were treated with posterior instrumented correction of displacements, followed by anterior instrumentation and fusion. The sacral fracture was left untreated. At 5-year followup, the patient had complete neurological recovery except for the right L5 root function. The long-segment lumbar fusion and the untreated displaced sacral fracture contributed to spinal imbalance, due to which the patient is now able to stand only in a crouched posture. Determining the optimal treatment for the case is presented due to the relative rarity of transverse sacral fracture and paucity of evidence-based treatment approaches. In patients with associated lumbar spine fractures that require extension of instrumentation to the upper lumbar spine, it is critical to restore sacropelvic alignment to achieve spinal balance. Adequate reduction of sacropelvic anatomy can be achieved with iliac screw fixation.

    Shift work is a risk factor for inflammation, hypertension, and cardiovascular disease. This increased risk cannot be fully explained by classical risk factors. Shift workers' behavioral and environmental cycles are typically misaligned relative to their endogenous circadian system. However, there is little information on the impact of acute circadian misalignment on cardiovascular disease risk in shift workers, independent of differences in work stress, food quality, and other factors that are likely to differ between night and day shifts. Thus, our objectives were to determine the independent effect of circadian misalignment on 24-h high-sensitivity C-reactive protein (hs-CRP; a marker of systemic inflammation) and blood pressure levels-cardiovascular disease risk factors-in chronic shift workers. Chronic shift workers undertook two 3-day laboratory protocols that simulated night work, comprising 12-hour inverted behavioral and environmental cycles (circadian misalignment) or simulated day work (circadian alignment), using a randomized, crossover design. Circadian misalignment increased 24-h hs-CRP by 11% ( p Circadian misalignment increased 24-h systolic blood pressure (SBP) and diastolic blood pressure (DBP) by 1.4 mmHg and 0.8 mmHg, respectively (both p ≤ 0.038). The misalignment-mediated increase in 24-h SBP was primarily explained by an increase in SBP during the wake period (+1.7 mmHg; p = 0.017), whereas the misalignment-mediated increase in 24-h DBP was primarily explained by an increase in DBP during the sleep opportunity (+1.8 mmHg; p = 0.005). Circadian misalignment per se increases hs-CRP and blood pressure in shift workers. This may help explain the increased inflammation, hypertension, and cardiovascular disease risk in shift workers.

    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.

    This letter describes the design, fabrication, and testing of a wireless bladder-pressure-sensing system for chronic, point-of-care applications, such as urodynamics or closed-loop neuromodulation. The system consists of a miniature implantable device and an external RF receiver and wireless battery charger. The implant is small enough to be cystoscopically implanted within the bladder wall, where it is securely held and shielded from the urine stream. The implant consists of a custom application-specific integrated circuit (ASIC), a pressure transducer, a rechargeable battery, and wireless telemetry and recharging antennas. The ASIC includes instrumentation, wireless transmission, and power-management circuitry, and on an average draws less than 9 μA from the 3.6-V battery. The battery charge can be wirelessly replenished with daily 6-h recharge periods that can occur during the periods of sleep. Acute in vivo evaluation of the pressure-sensing system in canine models has demonstrated that the system can accurately capture lumen pressure from a submucosal implant location.

    Environmental noise levels in the United States are increasing, yet there are few studies in which the nonauditory effects of workplace noise are assessed. In the current study, the authors examined chronic effects of noise on blood pressure and heart rate in 374 workers at an automobile plant. Data were collected from subjects prior to the start of their workshift. Participants completed questionnaires about diet, alcohol use, lifestyle, noise annoyance, use of hearing protection, noise exposure outside of the work environment, personal and family health histories, and demographic information. Resting blood pressure, heart rate, and body mass index were obtained. Noise exposure levels were extracted retrospectively from company records for each participant for the past 5 yr. Summary statistics were generated for each variable, and the authors performed bivariate correlations to identify any unadjusted associations. The authors then completed statistical modeling to investigate the effects of noise on blood pressure and heart rate, after they controlled for other variables (e.g., gender, race, age). The authors controlled for confounding variables, after which use of hearing protection in high-noise areas was a significant predictor of a decrease in both systolic and diastolic blood pressures. The results suggested that the reduction of noise exposure by means of engineering controls or by consistent use of hearing protection by workers may positively affect health outcomes.

    The use of negative pressure wound therapy (NPWT) is increasing in both the inpatient and outpatient settings. We conducted a systematic review on the efficacy and safety of NPWT for the treatment of chronic wounds in the home setting. We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and the Cumulative Index to Nursing and Allied Health Literature, up to June 2014. Two independent reviewers screened search results. Seven studies met our criteria for inclusion. Six of the studies compared NPWT devices to other wound care methods and one study compared two different NPWT technologies. Data were limited by variability in the types of comparator groups, methodological limitations, and poor reporting of outcomes. We were unable to draw conclusions about the efficacy or safety of NPWT for the treatment of chronic wounds in the home setting due to the insufficient evidence. Consensus is needed on the methods of conducting and reporting wound care research so that future studies are able inform decisions about the use of NPWT in the home environment for chronic wounds.

    Vascular dementia is a devastating disorder not only for the patient, but also for the family because this neurocognitive disorder breaks the patient's independence, and leads to family care of the patient with a high cost for the family. This complex disorder alters memory, learning, judgment, emotional control and social behavior and affects 4% of the elderly world population. The high blood pressure or arterial hypertension is a major risk factor for cerebrovascular disease, which in most cases leads to vascular dementia. Interestingly, this neurocognitive disorder starts after long lasting hypertension, which is associated with reduced cerebral blood flow or hypoperfusion, and complete or incomplete ischemia with cortical thickness. Animal models have been generated to elucidate the pathophysiology of this disorder. It is known that dendritic complexity determines the receptive synaptic contacts, and the loss of dendritic spine and arbor stability are strongly associated with dementia in humans. This review evaluates relevant data of human and animal models that have investigated the link between long-lasting arterial hypertension and neural morphological changes in the context of vascular dementia. We examined the effect of chronic arterial hypertension and aged in vascular dementia. Neural dendritic morphology in the prefrontal cortex and the dorsal hippocampus and nucleus accumbens after chronic hypertension was diskussed in the animal models of hypertension. Chronic hypertension reduced the dendritic length and spine density in aged rats.

    Full Text Available BACKGROUND Sacrum is a large triangular bone formed by the fusion of 5 sacral vertebrae. It lies obliquely at the posterior part of pelvic cavity between the two hip bones. It encloses a canal called the sacral canal. The lower opening of the sacral canal is called the sacral hiatus. It transmits the 5 th pair of sacral nerves, coccygeal nerves & filum terminale externa. AIMS & OBJECTIVES The aim of the present study is to find out the variations of sacral hiatus in this part of Northeast India. MATERIALS & METHODS The study was carried out in 104 dry human sacra to know the anatomical variations of sacral hiatus. The measurements were carried out with the help of a Vernier calliper, scale & a divider. RESULT & OBSERVATIONS Various shapes of sacral hiatus were observed as follows: Inverted U shaped (53.8%, inverted V shaped (29.8 %, irregular shaped (9.6 %, dumb-bell shaped (5.7 %, bifid (0.9%. The length of the sacral hiatus was found to be between 20-30 mm in 46.1% cases. The apex of the sacral hiatus was at the level of S4 vertebra in 46.1% specimens. The anteroposterior diameter of the sacral canal at the apex of the sacral hiatus ranged from 2-12 mm. CONCLUSIONS Variations of sacral hiatus is very common. The knowledge of such variations will definitely help the anaesthesiologists to take proper step while administering caudal epidural anaesthesia to increase the success rate of caudal epidural block.

    Visit-to-visit blood pressure variability has been shown to be an independent risk factor for cardiovascular diseases. High visit-to-visit blood pressure variability and endothelial dysfunction are observed in patients with chronic kidney disease. It is therefore assumed that high variability in visit-to-visit blood pressure measurements may be associated with endothelial dysfunction in these patients. The present study investigated the associations between visit-to-visit blood pressure variability and renal and endothelial function in patients with chronic kidney disease. We analyzed 150 consecutive patients with predialysis chronic kidney disease who visited our outpatient clinic from January 2006 to December 2010. The study examined the relationships between variability in visit-to-visit systolic blood pressure levels or mean systolic blood pressure (M SBP) and estimated glomerular filtration rate (eGFR) and flow-mediated dilation, an index of endothelial function. Variability in visit-to-visit systolic blood pressure showed a significant negative association with eGFR, independent of age, hemoglobin A1c, low-density lipoprotein (LDL) cholesterol and uric acid, whereas M SBP did not. Similarly, variability in SBP showed a significant negative association with flow-mediated dilation, independent of age, eGFR, HbA1c, LDL cholesterol and M SBP. These data indicate that variability in visit-to-visit blood pressure measurements is associated with impaired renal and endothelial function in patients with chronic kidney disease. This finding suggests that reducing blood pressure fluctuations might have beneficial effects in patients with chronic kidney disease, although this point needs to be addressed by future studies.

    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 Sacral fatigue fractures represent a frequently overlooked cause of low-back and buttock pain in athletes. A high index of clinical suspicion and MRI utilization can provide the accurate diagnosis. A 38-year-old male amateur, midfielder, soccer player presented to our department with aggravating right buttock pain during the previous month, following an increase in training intensity and frequency on an artificial turf field. A point of maximal tenderness was demonstrated over the area of the right sacroiliac joint. No radiographic abnormalities were observed. MRI of the pelvis revealed the presence of a stress fracture in the right sacral ala. The patient underwent conservative treatment and resumed playing soccer 12 weeks later, with no residual or recurrent clinical complaints. Apart from the recent change in training regimen, decreased shock absorption related to the physical properties of old generation artificial turf may have also been involved in this case.

    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.

    A 42-year-old woman developed lower extremity weakness and sensory loss 1 year after external and intracavitary radiotherapy for Stage IB carcinoma of cervix. She has been followed for 5 years posttreatment, and the neurologic abnormalities have persisted, but no evidence of recurrent carcinoma has been found. We believe this to be a rare case of sacral plexus radiculopathy developing as a late complication after radiotherapy. Suggestions are made for improving the radiotherapy technique to prevent this complication in future cases.

    Full Text Available Troy Sukhu,1 Michael J Kennelly,2 Raj Kurpad1 1Department of Urology, University of North Carolina, Chapel Hill, 2Department of Urology, Carolinas Medical Center, Charlotte, NC, USA Abstract: Overactive bladder (OAB symptoms of urgency, frequency, and urge incontinence currently affect a substantial portion of the population, especially as age increases. Sacral neuromodulation has become a popular option for refractory OAB symptoms over the past 2 decades. Studies have demonstrated that it is an effective treatment for OAB and urge incontinence as indicated by decreased number of voids, increased bladder capacity, and fewer leakage events. In addition, the effects have proved to be durable to multiple years following implantation. These benefits come at the expense of a high rate of adverse events, although with comparable long-term cost-effectiveness to botulinum toxin A. We aimed to review the literature that demonstrates that sacral neuromodulation continues to be an efficacious treatment for refractory OAB wet and dry patients, with continuously expanding indications.

    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.

    Emerging evidence has indicated that BRCC 36-mediated K63-linked ubiquitination modification was involved in diverse cellular functions , including endocytosis , apoptosis and DNA damage repair .We previously showed that activation of cGMP/PKG pathway con-tributed to the binding of BRCC36 and the pro-fibrotic factor Smad3.The current study tested the hypothesis that BRCC 36 functions as a negative regulator of transforming growth factor-beta ( TGF-β)/Smad3 pathway and participates in cardiac remodeling .In isolated adult mouse cardiac fibroblasts , we have demonstrated that TGF-β1 treatment significantly increased the expression of BRCC 36.Over-expression BRCC36 suppressed TGF-β1-induced Smad3 phosphorylation, nuclear translocation, extracellular matrix molecular expres-sion and cell proliferation .On the contrary, silencing BRCC36 by transfection of adenovirus-carrying BRCC36 shRNA potentiated to enhance the pro-fibrotic effect of TGF-β.In vivo, under chronic pressure overload condition-induced by transverse aortic constriction , myocardial pro-survival protein Bcl-2 and Mcl-1 expression were significantly decreased and the pro-apoptosis protein Puma was in-creased.However, the cardiac-specific over-expression of BRCC36 significantly increased myocardial Bcl-2 and Mcl-1 and inhibited Puma expression .Interestingly , we also found that sustained pressure overload resulted in a significant myocardial DNA injury in wild type mice, which was characterized by the increase of γH2AX level.However, cardiac-specific BRCC36 over-expression significantly decreased the level of γH2AX in the pressure overloaded heart in the transgenic mice , while effectively enhanced myocardial RAD 51 expression, a marker of DNA damage repair.Furthermore, BRCC36 over-expression effectively attenuated TAC-induced cardiac fibro-sis and remodeling in the transgenic mice , compared with the wild type mice .Collectively , the results have suggested that BRCC 36 ef-fectively protected heart

    Increased activity of the sympathetic system is an important feature contributing to the pathogenesis and progression of chronic heart failure. While the mechanisms and consequences of enhanced norepinephrine release from sympathetic nerves have been intensely studied, the role of the adrenal gland in the development of cardiac hypertrophy and progression of heart failure is less well known. Thus, the aim of the present study was to determine the effect of chronic cardiac pressure overload in mice on adrenal medulla structure and function. Cardiac hypertrophy was induced in wild-type mice by transverse aortic constriction (TAC) for 8 weeks. After TAC, the degree of cardiac hypertrophy correlated significantly with adrenal weight and adrenal catecholamine storage. In the medulla, TAC caused an increase in chromaffin cell size but did not result in chromaffin cell proliferation. Ablation of chromaffin α(2C)-adrenoceptors did not affect adrenal weight or epinephrine synthesis. However, unilateral denervation of the adrenal gland completely prevented adrenal hypertrophy and increased catecholamine synthesis. Transcriptome analysis of microdissected adrenal medulla identified 483 up- and 231 downregulated, well-annotated genes after TAC. Among these genes, G protein-coupled receptor kinases 2 (Grk2) and 6 and phenylethanolamine N-methyltransferase (Pnmt) were significantly upregulated by TAC. In vitro, acetylcholine-induced Pnmt and Grk2 expression as well as enhanced epinephrine content was prevented by inhibition of nicotinic acetylcholine receptors and Ca(2+)/calmodulin-dependent signaling. Thus, activation of preganglionic sympathetic nerves innervating the adrenal medulla plays an essential role in inducing adrenal hypertrophy, enhanced catecholamine synthesis and induction of Grk2 expression after cardiac pressure overload.

    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

  7. Variation of the Lateral Sacral Artery in relation to Sciatic Neuropathy

    Full Text Available The lateral sacral artery usually originates from the posterior trunk of the internal iliac artery. The current study of 342 specimens from 171 cadavers (79 male, 92 female investigated the origin and course of the lateral sacral artery. It was observed to arise from the posterior trunk in 79.1%. Occasionally it originated from the anterior trunk that occurred in 1%. It arose from the sciatic artery in 8.8%, from the superior gluteal artery in 16.8%, and from the inferior gluteal artery in 5.4%. Conversely, the lateral sacral artery is congenital absence in 0.3%. In addition, the lateral sacral artery was single, double, triple, and quadruple in 77.2%, 19.8%, 2.3%, and 0.3%, respectively. Consequently, variability of the lateral sacral artery origin is due to vascular demand as the lateral sacral artery plexus does arise from the earlier trunk development. With variability of the lateral sacral artery origin, there is a variability of the sciatic nerve supply. Knowing the variability of origins, surgeons have to avoid prolonged ligation of the internal iliac artery or its posterior trunk during surgical procedures which may lead to sciatic neuropathy. Therefore, the lateral sacral artery origin, course, and branches are important for clinicians to improve their knowledge and patient management.

    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 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. Understanding the relationship between the formation of PUs and the

    Hypovitaminosis D occurs early in the course of chronic kidney disease (CKD), and its association with cardiovascular morbidity and mortality is well known. In this study, we aimed to evaluate whether the degree of hypovitaminosis D may differently affect blood pressure (BP) and coronary artery calcification (CAC) in nondialyzed CKD patients. This study included 80 CKD patients with a creatinine clearance between 15 and 60 ml/min/1.73 m(2) and serum 25 hydroxivitamin D [25(OH)D] level hypovitaminosis D, were defined according to the median 25(OH)D value. Patients with severe hypovitaminosis D [25(OH)D hypovitaminosis D [25(OH)D >17.2 ng/ml; M-group]. No differences were found between the S and M-group in terms of diastolic BP and the presence of coronary calcification. In the multiple linear regression analysis, severe hypovitaminosis D was a predictor of 24-h, daytime and nighttime BP after controlling for a number of confounders. The severity of hypovitaminosis D was associated with increased BP in nondialyzed CKD patients. The degree of hypovitaminosis D was not related to CAC, which was equally elevated in both the severe and mild hypovitaminosis D groups.

  12. Back bugged: A case of sacral hydatid cyst

    Full Text Available Hydatid cyst of bone constitutes only 0.5 - 2% of all hydatidoses. The thoracic spine is the most common site of spinal hydatidoses. Primary hydatid cyst of the sacral spinal canal is rare. A 23-year-old gentleman had back pain five years ago. At that time he was evaluated and found to have a small cyst in S1 spinal canal, which was presumed to be a benign Tarlov′s cyst; and no treatment was offered. He continued to have back pain and also developed sciatica on the right side. Neurological examination presently revealed right S1 radiculopathy. Magnetic resonance imaging (MRI showed a large multiloculated cystic lesion extending from L5 to S2 spinal canal with bone erosion, both anteriorly and posteriorly. He underwent L5 to S2 laminectomy and excision of multiple cysts. The whole cyst was excised and cavity irrigated with sterilized formalin. A laparoscope was introduced in the cavity to look for extension into the pelvis and to confirm complete excision. Postoperatively, the patient received albendazole for two months. At 16 months follow-up the patient was asymptomatic. Hydatid cyst of sacrum is rare and can be missed at initial presentation. If the patient with a cystic lesion of sacral continues to have symptoms the diagnosis should be revaluated and prompt treatment should be offered.

    Following radiation therapy, marrow abnormalities noted on magnetic resonance imaging (MRI) are frequent and may mimic metastases. Specific radiotherapy changes are usually easily identifiable; however, traumatic lesions cause more interpretive difficulties. We assessed the incidence and MRI characteristics of insufficiency fractures in this population. During a 5-year span (1987-1991), 546 patients received pelvic radiotherapy for primary malignancies. MRI was performed in 25 of these patients at least 3 months after treatment. The mean dose in this group was 53 Gy. These MRI scans were retrospectively reviewed for the appearance of the sacrum with particular attention to the presence of insufficiency fractures. This was correlated with clinical course and scintigraphic findings. Presumed insufficiency fractures on MRI paralleled the sacral side of the sacroiliac joint, enhanced with Gd-DTPA, were most prominent or initially seen anteriorly, and had ill-defined margins on all imaging sequences. The incidence of occult sacral insufficiency fractures was at least 20%. Insufficiency fractures of the sacrum in the post-radiotherapy patient are a relatively frequent occurrence which can mimic metastases. Consideration of this phenomenon and knowledge of differential features may avoid overdiagnosis of osseous metastases. (orig.)

    2002-01-01

    A patient with juvenile rheumatoid arthritis and chronic iritis is reported with intraocular pressure near 30 mm Hg and previous episodes of intraocular pressure as high as 50 mm Hg despite maximally tolerated medical therapy. Because of the potential risk involved with a full-thickness filtration procedure, it was decided that a nonpenetrating deep sclerectomy would be appropriate, followed by placement of a collagen glaucoma drainage device to maintain aqueous outflow. Immediately postoperatively, intraocular pressure was stabilized. At 24 months postoperatively, intraocular pressure was well controlled at 15 mm Hg with patient receiving only Lotemax. No significant complications were noted at any point in the postoperative course. Because of the patient's predisposition for serious complications frequently associated with trabeculectomy, nonpenetrating deep sclerectomy with the collagen glaucoma drainage device was an effective alternative for this patient.

    Previously, a computer-based navigation system has not been used routinely for en-bloc resection of sacral tumors. In order to improve the accuracy of tumor resection, O-arm navigation was used to join anterior and posterior osteotomies during an en-bloc resection of a sacral Ewing's sarcoma. This case study describes the technique for en-bloc resection of a sacral Ewing's sarcoma guided by O-arm computer navigation and intraoperative neurophysiological monitoring (IONM). An 18-year-old male presented with weakness in his left lower extremity. MRI of the patient's spine showed a sacral mass causing compression of left S1 and S2 roots. A surgical resection was planned with anterior and posterior approaches. An O-arm computer navigation system was used to assist in meeting anterior osteotomy cuts with the posterior cuts to ensure complete resection of the sacral tumor with a safe margin. Computer-assisted navigation was used along with IONM during this procedure to help guide the surgical team in an adequate tumor resection. There were no complications related to the use of the O-arm or the navigation system. Computer navigation guidance is both useful and safe in sacral tumor resections. It enhanced the accuracy of the en-bloc removal of a sacral tumor with safe margins while protecting neural function and minimizing recurrence.

    This study was carried out to reveal the formation of the sacral plexus in the Eurasian Eagle Owls (Bubo bubo) and the nerves originating from this plexus. Five EEOs, three of them were male and two were female, were provided from Wildlife Rescue and Rehabilitation Center of Kafkas University and used as materials. Following the euthanizing of the animals, abdominal cavity was opened. The nerves of plexus sacrales were dissected and photographed. It was detected that the sacral plexus was formed by the ventral ramus of five synsacral nerves. Moreover, it was determined that the roots of the sacral plexus formed three trunks: the truncus cranialis, the truncus medius and the truncus caudalis in fossa renalis. The availability of the n. ischiofemoralis and the availability of n. parafibularis were detected in the EEOs. Five branches were specified as having segregated from the sacral plexus: the n. cutaneus femoralis caudalis, the mutual root of n. fibularis with n. tibialis (n. ischiadicus), the rami musculares, the n. coxalis caudalis and the ramus muscularis. It was observed that the sacral plexus was linked to the lumbar plexus by the n. furcalis, to the pudendus plexus via the n. bigeminus. Consequently, the anatomic structure of the EEO's sacral plexus, the participating synsacral nerves to plexus and the innervation areas of these nerves were revealed.

    2016-09-01

    Full Text Available Increased blood pressure variability (BPV, which can be experimentally induced by sinoaortic denervation (SAD, has emerged as a new marker of the prognosis of cardiovascular and renal outcomes. Considering that increased BPV can lead to organ-damage, the goal of the present study was to evaluate the effects of SAD on renal function in an experimental model of chronic kidney disease (CKD. SAD was performed in male Wistar rats 2 weeks before 5/6 nephrectomy and the animals were evaluated 4 weeks after the induction of CKD. Our data demonstrated that BPV was increased in SAD and CKD animals and that the combination of both conditions (SAD+CKD exacerbated BPV. The baroreflex sensitivity index was diminished in the SAD and CKD groups; this reduction was more pronounced when SAD and CKD were performed together. 5/6 nephrectomy led to hypertension, which was higher in SAD+CKD animals. Regarding renal function, the combination of SAD and CKD resulted in reduced renal plasma and blood flow, increased renal vascular resistance and augmented uraemia when compared to CKD animals. Glomerular filtration rate and BPV were negatively correlated in SAD, CKD and SAD+CKD animals. Moreover, SAD+CKD animals presented a higher level of glomerulosclerosis when compared to all other groups. Cardiac and renal hypertrophy, as well as oxidative stress, was also further increased when SAD and CKD were combined. These results show that SAD prior to 5/6 nephrectomy exacerbates renal dysfunction, suggesting that previous augmented BPV should be considered as an important factor to the progression of renal diseases.

    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.

    Sacral agenesis (or caudal regression syndrome) is a rare congenital anomaly involving various levels of coccygeal, sacral, and even lumbar or lower thoracic vertebral dysgenesis, as well as spinal cord abnormalities. A few cases have been previously reported in Korea, especially based upon MRI findings. We describe a case of a 4-year-old girl with partially bilateral agenesis of the sacrum (type II), and club-shaped (chisel-shaped) spinal cord disruption. We also review MRI findings of sacral agenesis, focused on classification and radiological findings.

    Background This meta-analysis evaluated the effect of noninvasive,positive pressure ventilation on severe,stable chronic obstructive pulmonary disease (COPD).Methods PUBMED,CNKI,Wanfang,EMBASE and the Cochrane trials databases were searched.Randomized controlled trials of patients with severe,stable COPD and receiving noninvasive positive pressure ventilation,compared with sham ventilation or no ventilation,were reviewed.The mortality,physiological and health related parameters were pooled to yield odds ratio (OR),weighted mean differences or standardized mean differences (SMD),with 95% confidence interval (C/).Results Eight parallel and three crossover randomized controlled trials met the inclusion criteria.Pooled analysis for parallel,randomized controlled trials showed noninvasive positive pressure ventilation:(1) Did not affect the 12-or 24-month mortality (OR 0.82,95% C/:0.48 to 1.41); (2) Improved the arterial carbon dioxide tension (SMD-0.88,95%C/:-1.43 to-0.34); (3) Did not improve forced expiratory volume in one second (SMD 0.20,95% C/:-0.06 to 0.46),maximal inspiratory pressure (SMD 0.01,95% C/:-0.28 to 0.29) or 6-minute walk distance (SMD 0.17,95% C/:-0.16 to 0.50); (4) Subgroup analysis showed noninvasive positive pressure ventilation improved the arterial carbon dioxide tension in hypercapnic patients.Pooled analysis for crossover randomized controlled trials did not show improvement in arterial blood gas or forced expiratory volume in one second with noninvasive positive pressure ventilation.Conclusions Noninvasive positive pressure ventilation improves the arterial carbon dioxide tension but does not improve the mortality,pulmonary function,or exercise tolerance and should be cautiously used in severe stable chronic obstructive pulmonary disease.

    Full Text Available Uterine incarceration is an uncommon but serious presentation in the emergency department that requires early recognition to improve maternal and fetal outcomes.Case: A 29-year-old female, at 12 weeks gestation, presented to the emergency department (ED with complaints of fever, sacral pain and urgency. Based on history and physical examination, she was found to have a retroverted, incarcerated uterus. After a failed attempt at reduction in the ED, her uterus was successfully reduced under general anesthesia.Discussion: Pain and urinary difficulties, such as retention and hesitancy, are frequent in pregnancy, yet incarcerated uterus is an uncommon emergency department diagnosis that often presents with these symptoms. Clues to the diagnosis include a retroverted uterus, urinary retention, and pain in a patient presenting in the third to fourth months of gestation. Treatment is by manual reduction of the uterus. Complications range from spontaneous abortion to uterine rupture.[WestJEM. 2008;9:232-234.

    The field of Sacral Neuromodulation is continually evolving and still in its infancy. Common dilemmas experienced with this therapy will be discussed in this article, including ways to avoid and manage them. The focus will be on test evaluations performed with either peripheral nerve evaluation (PNE) or staged procedure, the clinical effectiveness and safety of unilateral versus bilateral test stimulation for both the PNE and staged procedures, and best methods to determine the success of the trial phase. We will also discuss how to deal with the problem of declining efficacy of the device over time. The article presents a discussion on future technological innovations to enhance techniques and mode of positioning and use of leads, which along with a refined understanding of how neuromodulation is effective for different problems, will lead to better outcomes.

    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.

    2004-04-01

    Hypertension, as in adults, is a frequent complication found in children with chronic kidney disease (CKD). Indeed, hypertension has now become one of the most prevalent chronic diseases of childhood. The most recent data available (2003) indicate that at least 38% of children with CKD in the United States are receiving antihypertensive therapy. Only recently has it been shown in children that hypertension, traditionally considered a marker for disease severity in children, is additionally a significant and independent risk factor for accelerated deterioration of kidney function and progression of CKD and a significant risk factor for cardiovascular disease. The following review outlines the differences and similarities of childhood versus adult hypertension with respect to measurement, diagnosis, treatment, and consequence in CKD. The definition of hypertension changes continually as a child grows with or without CKD. Despite numerous guidelines, the diagnosis of childhood hypertension continues to be based on epidemiologic data rather than evidence. For children, the current definition includes 2 categories: high normal, which is blood pressure (BP) between the 90th and 95th percentile, and hypertensive, which is BP above the 95th percentile. The evaluation of all hypertensive children should include a complete assessment of end-organ damage, including eyes, cardiovascular system (including blood vessels), kidneys, and nervous system. For children with CKD and end-stage renal disease (ESRD), a high percentage have left ventricular hypertrophy (LVH). The finding of end-organ damage or comorbidity (CKD, diabetes) in any child is an absolute indication for immediate pharmacologic therapy, whereas the presence of hypertension above the 95th percentile in children without CKD warrants initial intervention such as life style modification. The guidelines for measurement of BP in children with CKD are similar to those in children without CKD and include casual BP

  11. COMPARISON OF SACRAL INDEX AND KIMURA BASE WING METHOD TO DETERMINE THE SEX OF SACRUM

    Directory of Open Access Journals (Sweden)

    Bichitrananda Roul

    2016-10-01

    Full Text Available BACKGROUND The sacrum (Vertebra Magnum is a large, flattened, triangular bone present at the base of spine, which is formed by fusion of sacral vertebra S1 to S5 and the fusion occurs between the age group of 18 to 30 years. It forms the posterosuperior part of bony pelvis articulating on either side with the corresponding hip bone at the sacroiliac joint. The dimensions of sacra vary in different sexes. Determination of sex of sacrum can be done by using various methods. In our study, comparison was done between sacral index and Kimura base wing method. MATERIALS AND METHODS A study to determine the sex of sacrum was carried on 50 sacra (25 male and 25 female sacra by two methods. One method used was sacral index and the other method was Kimura's base wing index. The measuring instrument used was sliding vernier caliper. Sacral index- the well-known method for determination of sex from sacrum and Kimura’s base wing method- another method for sex determination. Both are compared. The method of sacral index showed more accuracy rate as compared with Kimura's base wing index method. RESULTS By using sacral index, the % of bone identified as male sacrum was 64% and the % of bone identified as female sacrum was 68%. By using Kimura base wing method, 28% of male sacra and 24% of female sacra were identified in right side and 24% of male sacra and 20% of female sacra were identified in left side. CONCLUSIONS In our study, comparison was done between sacral index and Kimura base wing method in determining the sex of sacrum. From the above study, it was found that the method of sacral index showed more accuracy rate as compared with Kimura's base wing index method.

    2017-03-01

    A 50-year-old man with intractable anal pain attributed to proctalgia fugax underwent insertion of a sacral nerve stimulator via the right S3 vertebral foramen for pain control with good symptomatic relief. Thirteen months later, he presented with signs of sepsis. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a large presacral abscess. MRI demonstrated increased enhancement along the pathway of the stimulator electrode, indicating that the abscess was caused by infection introduced at the time of sacral nerve stimulator placement. The patient was treated with broad spectrum antibiotics, and the sacral nerve stimulator and electrode were removed. Attempts were made to drain the abscess transrectally using minimally invasive techniques but these were unsuccessful and CT guided transperineal drainage was then performed. Despite this, the presacral abscess progressed, developing enlarging gas locules and extending to the pelvic brim to involve the aortic bifurcation, causing hydronephrosis and radiological signs of impending sacral osteomyelitis. MRI showed communication between the rectum and abscess resulting from transrectal drainage. In view of the progressive presacral sepsis, a laparotomy was performed with drainage of the abscess, closure of the upper rectum and formation of a defunctioning end sigmoid colostomy. Following this, the presacral infection resolved. Presacral abscess formation secondary to an infected sacral nerve stimulator electrode has not been reported previously. Our experience suggests that in a similar situation, the optimal management is to perform laparotomy with drainage of the presacral abscess together with simultaneous removal of the sacral nerve stimulator and electrode.

    Full Text Available Background: The effect of kind of dialysis solution on the control of blood pressure and adequacy and efficacy of hemodialysis is a most debated and controversial issue.Methods: Twenty six chronic hemodialized patients in Ghaem hemodialysis center, Mashhad, Iran, in winter of the year 2004, enrolled this study for one month. The patients were dialyzed with bicarbonate buffer and were dialyzed in the next month with acetate. The kind of membranes and the dialysis machines were the same in both months. Systolic and diastolic pressures were measured before and after hemodialysis in at least three hemodialysis sessions, and he means recorded. The mean of the body weight were also recorded. In the same sessions of hemodialysis by measuring the urea, before and after hemodialysis, urea reduction ratio (URR, was also calculated. Statistical analysis was done with paired student t test for paired measurement, and independent t test for evaluating the effect of the kind of dialysate buffer on the measured parameters.Results: There were no significant statistical differences between acetate and bicarbonate dialysis solution buffers in the control of diastolic blood pressure. But use of acetate buffer resulted in more significant systolic blood pressure reduction compared with bicarbonate buffer (p=0.045. When adequacy of hemodialysis were compared between two kinds of buffers there were no significant statistical differences between them. When the effect of dialysate sodium concentration in the range utilized in two buffers, was evaluated on the systolic and diastolic pressure reduction, no significant differences, between two types of buffers attributable to the difference between dialysates sodium concentrations were found.Conclusion: Hemodialysis with both, acetate and bicarbonate buffers results in significant reductions in systolic and diastolic blood pressure, weight and urea ratio. Use of acetate buffer is more significantly associated with

  15. Hyperbaric oxygen in chronic traumatic brain injury: oxygen, pressure, and gene therapy.

    Harch, Paul G

    2015-01-01

    Hyperbaric oxygen therapy is a treatment for wounds in any location and of any duration that has been misunderstood for 353 years. Since 2008 it has been applied to the persistent post-concussion syndrome of mild traumatic brain injury by civilian and later military researchers with apparent conflicting results. The civilian studies are positive and the military-funded studies are a mixture of misinterpreted positive data, indeterminate data, and negative data. This has confused the medical, academic, and lay communities. The source of the confusion is a fundamental misunderstanding of the definition, principles, and mechanisms of action of hyperbaric oxygen therapy. This article argues that the traditional definition of hyperbaric oxygen therapy is arbitrary. The article establishes a scientific definition of hyperbaric oxygen therapy as a wound-healing therapy of combined increased atmospheric pressure and pressure of oxygen over ambient atmospheric pressure and pressure of oxygen whose main mechanisms of action are gene-mediated. Hyperbaric oxygen therapy exerts its wound-healing effects by expression and suppression of thousands of genes. The dominant gene actions are upregulation of trophic and anti-inflammatory genes and down-regulation of pro-inflammatory and apoptotic genes. The combination of genes affected depends on the different combinations of total pressure and pressure of oxygen. Understanding that hyperbaric oxygen therapy is a pressure and oxygen dose-dependent gene therapy allows for reconciliation of the conflicting TBI study results as outcomes of different doses of pressure and oxygen.

    This paper reports the first successful chronic monitoring (for 30 days) of blood pressure, heart rate, EEG, and physical activity in a freely moving bird, following (described) implantation of a commercially available (Data Sciences International) radiotelemetry device in a 1.6-kg broiler chicken. The tip of the device's pressure sensing catheter was introduced into the descending aorta via a leg (ischiadic) artery and, although the catheter was tied in place, circulation in the leg was maintained and leg function was not impaired. EEG was recorded from the device's paired sensing electrodes positioned on the surface of the telencephalon. Physiological and activity data collected by the radiotelemetry system over 2 complete 24-h periods, 1 and 4 weeks after implantation of the device, were analyzed with the system's own (Dataquest LabPRO) analysis software. The results presented are discussed mainly in terms of variation between light and dark periods.

    Pelvic reconstruction after sacral resection is challenging in terms of anatomical complexity, excessive loadbearing, and wide defects. Nevertheless, the technological development of 3D-printed implants enables us to overcome these difficulties. Here, we present a case of sacral osteosarcoma surgically treated with hemisacrectomy and sacral reconstruction using a 3D-printed implant. The implant was printed as a customized titanium prosthesis from a 3D real-sized reconstruction of a patient's CT images. It consisted mostly of a porous mesh and incorporated a dense strut. After 3-months of neoadjuvant chemotherapy, the patient underwent hemisacretomy with preservation of contralateral sacral nerves. The implant was anatomically installed on the defect and fixed with a screw-rod system up to the level of L3. Postoperative pain was significantly low and the patient recovered sufficiently to walk as early as 2 weeks postoperatively. The patient showed left-side foot drop only, without loss of sphincter function. In 1-year follow-up CT, excellent bony fusion was noticed. To our knowledge, this is the first report of a case of hemisacral reconstruction using a custom-made 3D-printed implant. We believe that this technique can be applied to spinal reconstructions after a partial or complete spondylectomy in a wide variety of spinal diseases.

    The primary aim of our study was to provide a comprehensive review of the clinical, imaging, and histopathological features of Tarlov cysts (TCs) and to report operative and nonoperative management strategies in patients with sacral TCs. A literature review was performed to identify articles that reported surgical and nonsurgical management of TCs over the last 10 years. Tarlov cysts are often incidental lesions found in the spine and do not require surgical intervention in the great majority of cases. When TCs are symptomatic, the typical clinical presentation includes back pain, coccyx pain, low radicular pain, bowel/bladder dysfunction, leg weakness, and sexual dysfunction. Tarlov cysts may be revealed by MR and CT imaging of the lumbosacral spine and must be meticulously differentiated from other overlapping spinal pathological entities. They are typically benign, asymptomatic lesions that can simply be monitored. To date, no consensus exists about the best surgical strategy to use when indicated. The authors report and discuss various surgical strategies including posterior decompression, cyst wall resection, CT-guided needle aspiration with intralesional fibrin injection, and shunting. In operative patients, the rates of short-term and long-term improvement in clinical symptoms are not clear. Although neurological deficit frequently improves after surgical treatment of TC, pain is less likely to do so.

  1. Denomination of the Sacral Building, its Innerspaces and Liturgical Articles

    Full Text Available Basing upon the material collected the article aims at reviewing denomination of liturgical – ritual objects. As to their meaning names are divided into groups depending upon what they name – a sacral object or its parts, liturgical books or articles, ritual clothes, etc. Concerning their origin there are Lithuanian and non-Lithuanian words. The latters may come from one language or be received through languages – intermediates. The conclusion is made that Latin or other foreign words remain important in the Lithuanian language as there are no proper Lithuanian words to name liturgical objects. The article has both practical and theoretical value. The data presented can be used when studying general laws of term origin and building as well as explaining the adaptation of borrowings in the Lithuanian language. It is relevant to continue the studies of this subject in order to encourage the building of Lithuanian equivalents both in this field and in those which lack Lithuanian names.

    The purpose of this study is to determine the reliability and validity of a goniometric measurement of the vertical angle of the sacrum and sacral angle (SA), and their relationships to lumbar degeneration.A herniated lumbar disc is one of the most frequent medical issues. Investigators in a number of studies have reported associated risk factors for prevalent disc degeneration. Atypical lumbosacral angles and curvature are thought to contribute to the degradation of the spine by many researchers. This study analyzed 360 patients referred to our clinic from 2013 to 2015 due to low back pain. A cross-sectional case-control study was designed in order to compare the sagittal alignment of the lumbosacral area in 3 groups of patients suffering from LBP. A total 120 patients were in a control group with a normal lumbar magnetic resonance imaging (MRI), 120 patients had lumbar disk herniation (LDH), and 120 patients had spinal stenosis. From the sagittal plan of lumbar MRI, SA and vertical angle of sacral curvature (VASC) were determined and then analyzed.The means of VASC in these groups were: 38.98 (SD: 6.36 ± 0.58), 40.89 (SD: 7.69 ± 0.69), and 40.54 (SD: 7.13 ± 0.92), respectively (P = 0.089). Moreover, studies of SA in 3 groups showed that the means of SA were: 39.30 (SD: 6.69 ± 0.63), 40.52 (SD: 7.47 ± 0.65), and 35.63 (SD: 6.07 ± 0.79), respectively. Relation between SA and spinal stenosis was just statistically significant (P ≤ 0.05).One significant limitation of our study is the lack of standing MRI for increased accuracy of measurement. However, we were reluctant to give patients needless exposure to radiation from conventional X-ray, and instead used MRI scans. We did not find any significant correlation between the VASC and LDH in lumbar MRI. Also, SA is not an independent risk factor for LDH in men and women. We suggested that there are several biomechanical factors involved in LDH.

Counter pressure was calculated by Doppler venous pressure index (VPI. The aim of this study was to verify the value VPI in the choice of GES. A total of 1212 LL of 606 patients subjected to VPI measurements VPI correlated with the various sites of reflux (R and C of Clinical-Etiology-Anatomy-Pathophysiology (CEAP classification. The difference between standing VPI the and normal values=counter pressure to be applied by GES. Questionnaire to 96 patients with CVI/VVLL wearing GES. 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.

    Metabolic acidosis has profound effects on vascular tone. This study investigated the in vivo effects of acute metabolic acidosis (AMA) and chronic metabolic acidosis (CMA) on hemodynamic parameters and endothelial function. CMA was induced by ad libitum intake of 1% NH4Cl for 7 days, and AMA was induced by a 3-h infusion of 6 M NH4Cl (1 mL/kg, diluted 1:10). Phenylephrine (Phe) and acetylcholine (Ach) dose-response curves were performed by venous infusion with simultaneous venous and arterial blood pressure monitoring. Plasma nitrite/nitrate (NOx) was measured by chemiluminescence. The CMA group had a blood pH of 7.15±0.03, which was associated with reduced bicarbonate (13.8±0.98 mmol/L) and no change in the partial pressure of arterial carbon dioxide (PaCO2). The AMA group had a pH of 7.20±0.01, which was associated with decreases in bicarbonate (10.8±0.54 mmol/L) and PaCO2 (47.8±2.54 to 23.2±0.74 mmHg) and accompanied by hyperventilation. Phe or ACh infusion did not affect arterial or venous blood pressure in the CMA group. However, the ACh infusion decreased the arterial blood pressure (ΔBP: -28.0±2.35 mm Hg [AMA] to -4.5±2.89 mmHg [control]) in the AMA group. Plasma NOx was normal after CMA but increased after AMA (25.3±0.88 to 31.3±0.54 μM). These results indicate that AMA, but not CMA, potentiated the Ach-induced decrease in blood pressure and led to an increase in plasma NOx, reinforcing the effect of pH imbalance on vascular tone and blood pressure control.

    Full Text Available CONTEXT: The exact mechanism involved in changes in blood pressure and peripheral vascular resistance during pregnancy is unknown. OBJECTIVE:To evaluate the importance of endothelium-derivated relaxing factor (EDRF and its main component, nitric oxide, in blood pressure and vascular reactivity in pregnant rats. DESIGN: Clinical trial in experimentation animals. SETTING: University laboratory of Pharmacology. SAMPLE: Female Wistar rats with normal blood pressure, weight (152 to 227 grams and age (90 to 116 days. INTERVENTION: The rats were divided in to four groups: pregnant rats treated with L-NAME (13 rats; pregnant control rats (8 rats; virgin rats treated with L-NAME (10 rats; virgin control rats (12 rats. The vascular preparations and caudal blood pressure were obtained at the end of pregnancy, or after the administration of L-NAME in virgin rats. MAIN MEASUREMENTS: The caudal blood pressure and the vascular response to acetylcholine in pre-contracted aortic rings, both with and without endothelium, and the effect of nitric oxide inhibition, Nw-L-nitro-arginine methyl-ester (L-NAME, in pregnant and virgin rats. The L-NAME was administered in the drinking water over a 10-day period. RESULTS: The blood pressure decreased in pregnancy. Aortic rings of pregnant rats were more sensitive to acetylcholine than those of virgin rats. After L-NAME treatment, the blood pressure increased and relaxation was blocked in both groups. The fetal-placental unit weight of the L-NAME group was lower than that of the control group. CONCLUSION: Acetylcholine-induced vasorelaxation sensitivity was greater in pregnant rats and that blood pressure increased after L-NAME administration while the acetylcholine-induced vasorelaxation response was blocked.

    Sigma receptors are Ca(2+)-sensitive, ligand-operated receptor chaperones at the mitochondrion-associated endoplasmic reticulum membrane. This study describes the effect of the sigma receptor 1 agonist pregnenolone sulfate on intraocular pressure (IOP) and sigma receptor 1 expression in rat retinas after chronic ocular hypertension. Chronic ocular hypertension was induced by occlusion of episcleral veins. Retinal histological sections were obtained to determine inner plexiform layer thickness and the number of cell bodies in the ganglion cell layer. Sigma receptor expression in rat retinas was analyzed by RT-PCR and Western blotting. Cauterization caused IOP to increase >73%, and the pressure was maintained for 2 months. A time-dependent loss of ganglion cells and retinal thickness occurred at elevated IOP. High IOP decreased sigma receptor 1 expression during the first week, but expression was increased at 8 weeks. Injected pregnenolone significantly decreased IOP, prevented ganglion cell loss, protected inner plexiform layer thickness, and increased sigma receptor 1 expression in episcleral vein-cauterized rats. Sigma receptors appear to be neuroprotective and potential targets for glaucoma therapeutics.

    The purpose of the study was to examine the value of regular measurements of plasma renin concentration (PRC) in selecting those chronic haemodialysis patients suitable for bilateral nephrectomy to prevent development of uncontrollable hypertension. Regular measurements of arterial blood pressure (BP) and PRC were performed during one year in 31 patients undergoing regular haemodialysis because of end-stage renal disease. Among 18 patients with PRC greater than or equal to 100 micro Goldblatt units per ml plasma (microGU/ml) systolic and/or diastolic hypertension persisted or developed in 12. In contrast, among 13 patients with PRC greater than 100microGU/ml, BP became normal in all but one, who had a slightly increased systolic BP. However, hypertension was mild and easily controlled by conventional therapy in all except one, who probably had an overlying volume-dependent hypertension. Therefore, bilateral nephrectomy was not necessary in any case. The results indicate that hypertension in the majority of chronic haemodialysis patients with high PRC can be adequately controlled without surgical intervention and that regular measurements of PRC have no practical value in forecasting the development of uncontrollable hypertension in chronic haemodialysis patients.

    In patients with obstructive sleep apnea (OSA) syndrome and chronic respiratory insufficiency one of the options of treatment is bilevel positive airway pressure (BPAP) during sleep. The aim of the study was to find out what are the factors influencing the early results of BPAP treatment in such OSA patients. The study was carried out in 55 adult obese patients (mean body mass index 45 ± 7 kg/m(2)), severe OSA syndrome (mean apnea/hypopnea index 62 ± 19), and chronic respiratory insufficiency (mean PaCO(2) 54 ± 5.7 torr) who underwent polysomnography during BPAP treatment. In 31 patients (56%) the mean SaO(2) during sleep was <88% despite the optimal BPAP and oxygen titration: 83 ± 4% during NREM and 81 ± 7% during REM sleep vs. 91 ± 2% and 90 ± 3%, respectively, in the remaining 24 patients (p < 0.001). The patients with advanced hypoxemia during sleep and BPAP treatment had lower forced vital capacity (2.2 ± 0.9 vs. 2.7 ± 0.8 l, p < 0.05), lower diurnal PaO(2) (49 ± 8 vs. 54 ± 7 torr), higher diurnal PaCO(2) (57 ± 5 vs. 52 ± 5 torr, p < 0.01), and higher PaCO(2) during sleep (75 ± 13 vs. 59.5 ± 7.5 torr). In conclusion, in obese patients with severe OSA syndrome and chronic alveolar hypoventilation there is a risk of sleep hypoxemia during BPAP treatment, despite optimal pressure titration.

    Objective:To determine frequency of factors leading to poor outcome of non-invasive positive pressure ventilation in acute exacerbation of chronic obstructive pulmonary disease. Methods:This cross sectional study was conducted at our center between May 2012 and November 2012. A total of 195 diagnosed patients of acute exacerbation of chronic obstructive pulmonary disease meeting the inclusion criteria were selected from the ER department. At the time of admission age was inquired BP, respiratory rate and oxygen saturation will be noted and pedal edema was assessed and investigations were sent for pH assessment. Noninvasive positive pressure ventilation (NIPPV) using BiPAP was applied in spontaneous mode by the help of oronasal mask. Presence of respiratory rate (less than 12/min), systolic blood pressure140 bpm was taken as poor outcome. Results:The average age of the cases was 61.9±9.3 years with male to female ratio being 1.5:1. NIPPV was successful in 151 (77.4%) cases and 44 (22.6%) cases were underwent endotracheal intubation. About 38 (44.7%) of patients with oxygen saturation (82%-86%) had poor prognosis. A total of 40 (55.6%) of patients with pH range 7.20-7.26, required endotracheal intubation, 43 (66.2%) with pedal edema underwent endotracheal intubation. While 29 (24.16%) patients of age>60 years needed endotracheal intubation. Conclusions:In this study, NIPPV was successful in 77.4%cases and 22.6%cases were underwent endotracheal intubation. Pedal edema was the most common factor leading to poor outcomes while age>60 years was the least common factor, 66.2%and 24.2%respectively.

    Background The evidence for non-invasive positive pressure ventilation (NIPPV) used in patients with severe stable chronic obstructive pulmonary disease (COPD) is insufficient.The aim of the meta-analysis was to assess the treatment effects of long-term NIPPV on gas change,lung function,health-related quality of life (HRQL),survival and mortality in severe stable COPD patients.Methods Randomized controlled trials (RCTs) and crossover studies comparing the treatment effects of NIPPV with conventional therapy were identified from electronic databases and reference lists from January 1995 to August 2010.Two reviewers independently assessed study quality.Data were combined using Review Manager 5.0.Both pooled effects and 95% confidence intervals were calculated.Results Five RCTs and one randomized crossover study with a total of 383 severe stable COPD patients were included.NIPPV improved gas change significantly when using a higher inspiratory positive airway pressures.The weighted mean difference (WMD) for the partial pressure of carbon dioxide in artery (PaCO2) was -3.52 (-5.26,-1.77) mmHg and for the partial pressure of oxygen in artery (PaO2) 2.84 (0.23,5.44) mmHg.There were significant improvements in dyspnea and sleep quality,but gained no benefits on lung function.The standardized mean difference (SMD) for the forced expiratory volume in 1 second (FEV1)was 0.00 (0.29,0.29).And the benefits for exercise tolerance,mood,survival and mortality remained unclear.Conclusions Patients with severe stable COPD can gain some substantial treatment benefits when using NIPPV,especially improvements in gas change,dyspnea and sleep quality.Studies of high methodological quality with large population,especially those based on a higher inspiratory positive airway pressures are required to provide more evidences.

    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.

    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.

    Full Text Available Abstract Background Primary sacral tumors are rare and experience related to accompanying effects of these tumors is therefore limited to observations on a small number of patients. Case presentation In this case report we present a patient with a history of primary sacral chondrosarcoma, an infection of an implanted spinal stabilization device and discuss the challenges that resulted from a colonic fistula associated with large, life threatening abscesses as late complications of radiotherapy. Conclusion In patients with sacral tumors enterocutaneous fistulas after free musculotaneous free flaps transfer are rare and can occur in the setting of surgical damage followed by radiotherapy or advanced disease. They are associated with prolonged morbidity and high mortality. Identification of high-risk patients and management of fistulas at an early stage may delay the need for subsequent therapy and decrease morbidity.

    Early detection of non blanching erythema (pressure ulcer category I) is necessary to prevent any further skin damage. An objective method to discriminate between blanching/non blanching erythema is presently not available. The purpose of this investigation was to explore if a non invasive objective method could differentiate between blanching/non blanching erythema in the sacral area of patients undergoing hip fracture surgery. Seventy-eight patients were included. The sacral area of all patients was assessed using (i) conventional finger-press test and (ii) digital reading of the erythema index assessed with reflectance spectrophotometry. The patients were examined at admission and during 5 days postsurgery. Reflectance spectrophotometry measurements proved able to discriminate between blanching/non blanching erythema. The reliability, quantified by the intra-class correlation coefficient, was excellent between repeated measurements over the measurement period, varying between 0·82 and 0·96, and a significant change was recorded in the areas from day 1 to day 5 (P < 0·0001). The value from the reference point did not show any significant changes over the same period (P = 0·32). An objective method proven to identify early pressure damage to tissue can be a valuable tool in clinical practice.

    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.

    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

    To assess the contribution of right ventricular (RV) trabeculae and papillary muscles (TPM) to RV mass and volumes in controls and patients with pulmonary arterial hypertension (PAH). Furthermore, to evaluate whether TPM shows a similar response as the RV free wall (RVFW) to changes in pulmonary artery pressure (PAP) during follow-up. 50 patients underwent cardiac magnetic resonance (CMR) and right heart catheterization at baseline and after one-year follow-up. Furthermore 20 controls underwent CMR. RV masses were assessed with and without TPM. TPM constituted a larger proportion of total RV mass and RV end-diastolic volume (RVEDV) in PAH than in controls (Mass: 35 ± 7 vs. 25 ± 5 %; p TPM mass was related to the RVFW mass in patients (baseline: R = 0.65; p TPM from the assessment resulted in altered RV mass, volumes and function than when included (all p TPM mass (β = 0.44; p = 0.004) but not the changes in RVFW mass (p = 0.095) were independently related to changes in PAP during follow-up. RV TPM showed a larger contribution to total RV mass in PAH (~35 %) compared to controls (~25 %). Inclusion of TPM in the analyses significantly influenced the magnitude of the RV volumes and mass. Furthermore, TPM mass was stronger related to changes in PAP than RVFW mass. Our results implicate that TPM are important contributors to RV adaptation during pressure overload and cannot be neglected from the RV assessment.

    Full Text Available Extensive skin defect represents a real problem and major challenge in plastic and reconstructive surgery. On one hand, skin grafts offer a practical method to deal with skin defects despite their unsuitability for several complicated wounds. On the other hand, negative pressure wound therapy (NPWT, applied before skin grafting, promotes granulation tissue growth. The aim of the study is to evaluate the improvement in wound healing given by the merger of these two different approaches. We treated 23 patients for large wounds of multiple factors. Of these, 15 were treated with the application of V.A.C.® Therapy (KCI Medical S.r.l., Milan, Italy, in combination with skin grafts after a prior unsuccessful treatment of 4 weeks with mesh skin grafts and dressings. Another 8 were treated with only mesh skin graft. Pain reduction and wound area reduction were found statistically significant (p<0.0009, p<0.0001. Infection was resolved in almost all patients. According to our study, the use of the negative pressure wound therapy over mesh skin grafts is significantly effective especially in wounds resistant to conventional therapies, thereby improving the rate of skin graft take.

  2. Heliox and noninvasive positive-pressure ventilation: a role for heliox in exacerbations of chronic obstructive pulmonary disease?

    Evidence-based respiratory therapy for exacerbations of chronic obstructive pulmonary disease (COPD) includes oxygen, inhaled bronchodilators, and noninvasive positive-pressure ventilation. Examining the physics of gas flow, a case can be made either for or against the use of helium-oxygen mixture (heliox) in the care of patients with COPD. The evidence for the use of heliox in patients with COPD exacerbation is not strong at present. Most of the peer-reviewed literature consists of case reports, case series, and physiologic studies in small samples of carefully selected patients. Some patients with COPD exacerbation have a favorable physiologic response to heliox therapy, but predicting who will be a responder is difficult. Moreover, the use of heliox is hampered by the lack of widespread availability of an approved heliox delivery system. Appropriately designed randomized controlled trials with patient-important outcomes, such as avoidance of intubation, decreased intensive-care-unit and hospital days, and decreased cost of therapy, are sorely needed to establish the role of heliox in patients with COPD exacerbation, including those receiving noninvasive positive-pressure ventilation. Lacking such evidence, the use of heliox in patients with COPD exacerbation cannot be considered standard therapy.

    In nondialysis chronic kidney disease, ambulatory blood pressure (ABP) performs better than clinic BP in predicting outcome, but whether repeated assessment of ABP further refines prognosis remains ill-defined. We recruited 182 consecutive hypertensive patients with nondialysis chronic kidney disease who underwent 2 ABPs 12 months apart to evaluate the enhancement in risk stratification provided by a second ABP obtained 1 year after baseline on the risk (hazard ratio and 95% confidence interval) of composite renal end point (death, chronic dialysis, and estimated glomerular filtration rate decline ≥40%). The difference in daytime and nighttime systolic BP between the 2 ABPs (daytime and nighttime bias) was added to a survival model including baseline ABP. Net reclassification improvement was also calculated. Age was 65.6±13.4 years; 36% had diabetes mellitus and 36% had previous cardiovascular event; estimated glomerular filtration rate was 42.2±19.6 mL/min per 1.73 m(2), and clinic BP was 145±18/80±11 mm Hg. Baseline ABP (daytime, 131±16/75±10 and nighttime, 122±18/66±10 mm Hg) and daytime/nighttime BP goals (58.2% and 43.4%) did not change at month 12. Besides baseline ABP values, bias for daytime and nighttime systolic BP linearly associated with renal outcome (1.12, 1.04-1.21 and 1.18, 1.08-1.29 for every 5-mm Hg increase, respectively). Classification of patients at risk improved when considering nighttime systolic level at second ABP (net reclassification improvement, 0.224; 95% confidence interval, 0.005-0.435). Patients with first and second ABPs above target showed greater renal risk (2.15, 1.29-3.59 and 1.71, 1.07-2.72, for daytime and nighttime, respectively). In nondialysis chronic kidney disease, reassessment of ABP at 1 year further refines renal prognosis; such reassessment should specifically be considered in patients with uncontrolled BP at baseline.

    The original hypoxemia, hypercapnia, high pulmonary hypertension, high resistance of microcirculation vessels, right volumetric ventricular overload, persistent sub-edema of pulmonary intersticium as well as disparity of ventilation and perfusion between both lungs are the main problems in patients with chronic obstructive disease of the lungs (CODL). Such patients are, as a rule, intolerant to the independent lung collaboration or artificial single-stage ventilation (ASV). Patients with respiratory insufficiency, stages 2 and 3, and with a pronounced impaired type of ventilation have originally a deranged blood gas composition, like hypoxemia or hypercapnia. The application of volume-controllable bi-pulmonary ASV in such patients maintains an adequate gas exchange hemodynamics. However, ASV is accompanied by a significantly reduced gas-exchange function of the single ventilated lung and by essentially worsened intrapulmonary hemodynamics. Therefore, what is needed is to use alternative methods of independent lung ventilation in order to eliminate the gas-exchange impairments and to enable surgical interventions at thoracic organs in such patients (who are intolerant to ASV). A choice of a method and means of oxygen supply to the independent lung is of great importance. The possibility to avoid a high pressure in the airways, while maintaining, simultaneously, an adequate gas exchange, makes the method related with maintaining a constant positive pressure in the airways (CPPA) a priority one in case of CODL patients. The use of constant high-frequency ventilation in the independent lung in patients with obstructive pulmonary lesions does not improve the gas exchange or hemodynamics. Simultaneously, a growing total pulmonary resistance and an increasing pressure in the pulmonary artery are observed. Consequently, the discussed method must not be used for the ventilation support of the independent lung in patients with the obstructive type of the impaired external

    Background Blood pressure (BP) is often inadequately controlled in patients with chronic kidney disease (CKD). Previous reports of the longitudinal association between achieved level of BP and end-stage renal disease (ESRD) have not incorporated time-updated BP with appropriate adjustment for known confounders. Objective To assess the association between baseline and time-updated systolic BP (SBP) with the progression of CKD. Design Observational, prospective cohort study (ClinicalTrials.gov identifier: NCT00304148) Setting Seven US clinical centers Patients Participants of the Chronic Renal Insufficiency Cohort (CRIC) Study (N=3,708) followed for a median (25th, 75th percentiles) of 5.7 (4.6, 6.7) years Measurements The mean of three seated SBP measurements were used as the visit-specific SBP. SBP was time-updated as the mean of that visit and all prior visits. Outcomes were ESRD and the composite renal endpoint of ESRD (dialysis or transplantation) or halving of the estimated glomerular filtration rate (eGFR). Analyses investigating baseline and time-updated SBP utilized traditional Cox proportional hazards models and marginal structural models, respectively. Results SBP was ≥130 mmHg at all study visits in 19.2% of participants, and ≥140 mmHg in 10.6%. The hazard ratio (95% confidence interval) for ESRD among participants with SBP 130–139 mmHg, compared to SBP <120 mmHg, was 1.46 (1.13–1.88) using only baseline data, and was 2.37 (1.48–3.80) using all available time-updated data. Among those with SBP ≥140 mmHg, corresponding hazard ratios were 1.46 (1.18–1.88) and 3.37 (2.26–5.03), respectively. Limitations SBP was measured once annually, and the CRIC Study cohort is not a random sample. Conclusions Among participants in the CRIC Study, time-updated SBP over 130 mmHg was more strongly associated with progression of CKD than analyses based on baseline SBP. Funding The CRIC Study is funded under cooperative agreements from the National Institute of

    Patient: Female, 51 Final Diagnosis: Fecal incontinence Symptoms: Constipation • fecal incontinence Medication: — Clinical Procedure: Sacral nerve stimulator Specialty: Gastroenterology and Hepatology Objective: Rare co-existance of disease or pathology Background: Fecal incontinence and constipation are common gastrointestinal complaints, but rarely occur concurrently. Management of these seemingly paradoxical processes is challenging, as treatment of one symptom may exacerbate the other. Case Report: A 51-year-old female with lifelong neurogenic bladder secondary to spina bifida occulta presented with progressive symptoms of daily urge fecal incontinence as well as hard bowel movements associated with straining and a sensation of incomplete evacuation requiring manual disimpaction. Pelvic floor testing showed poor ability to squeeze the anal sphincter, which indicated sphincter weakness as a major contributor to her fecal incontinence symptoms. Additionally, on defecography she was unable to widen her posterior anorectal angle or relax the anal sphincter during defecation consistent with dyssynergic defecation. A sacral nerve stimulator was placed for management of her fecal incontinence. Interestingly, her constipation also dramatically improved with sacral neuromodulation. Conclusions: This unique case highlights the emerging role of sacral nerve stimulation in the treatment of complex pelvic floor dysfunction with improvement in symptoms beyond fecal incontinence in a patient with dyssynergic-type constipation.

    Full Text Available Identification of sex by human skeletal remains is a critical problem and is very important in anthropological and medico legal works. Bones often survive the process of decay and therefore provide the major evidence of human age and sex after death. Over the years different authors had carried various types of measurements on human sacra of different races and regions. The present study carried out 81 sacra of unknown sex contains 45 male and 36 female sacra identified by physical characteristics. They were collected from Telangana and Andhra Pradesh region. India may be divided into four regions like North part, South part, West part, and East part for different study purpose on local population. In the present study mean sacral index in males is 104.08 and females are 115.72. The male mean sacral index value of present study is more than the values of Eastern part, north part, other worker of Southern part of India and western part except in Western part in Western Rajasthan population. The female mean sacral index value of present study is higher than the observation of Eastern part, other workers of Southern part of India, Varanasi and Jammu of north part of India and Saurashtra region of western region of India. Observations of the workers from remaining areas of Western part of India and Agra region of North India is higher than the present study. The studies on Indian population suggest that mean sacral index in females is higher than that of males.

    Objetive:To evaluate the efficacy of preoperative transcatheter arterial embolization in the treatment of sacral chordoma,and to explore the choice of embolization timing. Methods:32 patients underwent the posterior approach after TAE of the main arteries that supplied the sacral chordoma. Intraoperative bleeding amount of each patient was recorded and compared between-group differences at different operation times. Results: After embolization, 12 patients were received resection within 24 hours (group A),that of 10 cases between 24 ~ 48h (group B), of another 10 cases between 48~ 72h (group C). All of the 32 tumors were removed intact with intraoperative bleeding about (894±199)ml, without any shock or death,nor injuries on abdominal organs such as rectum and ureter. There was no statistical significance in tumor size among group A,B and C (P>0.05). Data gave statistical significance in intraoperative blood loss between group A and B (P<0.01) ,there was no statistical differences between group B and C (P>0.05), in spite of group B slightly less than group C. Conclusion: Preoperative TAE for excising the sacral tumor can significantly decrease intraoperative blood loss, make the surgical field clear,and facilitate the maximal removal of the sacral chordoma. It would be best to select the embolization timing within 24 hours before surgical operation.

    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.

    Full Text Available Background: The reliability and success of caudal epidural anesthesia depends on anatomic variations of sacral hiatus (SH as observed by various authors. SH is an important landmark during caudal epidural block (CEB.The purpose of the present study was to clarify the morphometric characteristics of the SH in human Egyptian dry sacra and pelvic radiographs and identification of nearest ony landmarks to permit correct and uncomplicated caudal epidural accesses. Methods: The present study was done on 46 human adult Egyptian dry sacra. The maximum height, midventral curved length, and maximum breadth of each sacrum were measured and sacral and curvature indices were calculated. According to sacral indices, sacra were divided into 2 groups (22 male and 24 female sacra. SH was evaluated in each sacrum according to its shape, level of its apex, and base according to sacral and coccygeal vertebrae, length, anteroposterior (AP diameter at its apex, and transverse width at its base. Linear distances were measured between the apex of SH and second sacral foramina, right and left superolateral sacral crests. The distance between the 2 superolateral sacral crests also was measured. Results: The most common types of SH were the inverted U and inverted V (in male and inverted V and dumbbell shaped (in female. Absent SH was observed in male group only. The most common location of SH apex was at the level of S4 in all groups of dry sacra and S3 in all groups of lumbosacral spine radiographs, whereas S5 was the common level of its base. The mean SH length, transverse width of its base, and AP diameter of its apex were 2.1±0.80, 1.7±0.26, and 0.48±0.19 cm. Female sacra showed narrower SH apex than male. The distance between the S2 foramen and the apex of the SH was 4.1±1.14, 3.67±1.21, and 4.48±1.01 cm in total, female and male sacra, respectively. Conclusion: Sacrum and SH showed morphometric variations in adult Egyptians. The equilateral triangle is an

    Propranolol is known to decrease portal pressure by reducing blood flow of portal vein. Per-rectal portal scintigraphy with Tc-99m pertechnetate has been introduced to evaluate the portal circulation and early diagnosis of liver cirrhosis. We evaluated the effects of propranolol on portal circulation by using per-rectal portal scintigraphy. We analyzed the portal hemodynamics by per-rectal portal scintigraphy in 51 patients with liver cirrhosis, 10 chronic hepatitis and 10 normal subjects. 38 patients with cirrhosis underwent per-rectal portal scintigraphy before and after propranolol medication. Per-rectal portal scintigraphy was performed after per-rectal administration of 370 MBq of Tc-99m pertechnetate. The shunt index was calculated as the ratio, expressed as a percentage of heart radioactivity to the sum of heart and liver radioactivity during the first 30 seconds. The shunt index in 40 patients with cirrhosis (59.8{+-}27.2%) was significantly higher than that of normal control (5.0{+-}1.2%, p<0.01) and chronic hepatitis (11.4{+-}3.5%, p<0.01). Shunt index was significantly different according to Child's classification and the degree of esophgageal varix (p<0.01). After propranolol medication, shunt index was significantly decreased from 59.9{+-}27.3% to 51.3{+-}15.3% (p<0.01) in 38 patients with liver cirrhosis. There was no significant difference of the amount of shunt index reduction after propranolol according to Child's classification and the degree of esophageal varix. The effect of propranolol on portal circulation was demonstrated as decreasing shunt index on per-rectal portal scintigraphy in patients with liver cirrhosis. Per-rectal portal scintigraphy may be useful to evaluate the portal circulation and to predict the effect of propranolol in patients with liver cirrhosis.

    Among those with moderate-to-advanced chronic kidney disease, the relationship between blood pressure (BP) and cardiovascular disease seems U shaped but is loglinear in apparently healthy adults. The SHARP (Study of Heart and Renal Protection) randomized 9270 patients with chronic kidney disease to ezetimibe/simvastatin versus matching placebo and measured BP at each follow-up visit. Cox regression was used to assess the association between BP and risk of cardiovascular disease among (1) those with a self-reported history of cardiovascular disease and (2) those with no such history and, based on plasma troponin-I concentration, a low probability of subclinical cardiac disease. A total of 8666 participants had a valid baseline BP and troponin-I measurement, and 2188 had at least 1 cardiovascular event during follow-up. After adjustment for relevant confounders, the association between systolic BP and cardiovascular events was U shaped, but among participants without evidence of previous cardiovascular disease, there was a positive loglinear association throughout the range of values studied. Among those with the lowest probability of subclinical cardiac disease, each 10 mm Hg higher systolic BP corresponded to a 27% increased risk of cardiovascular disease (hazard ratio, 1.27; 95% confidence interval, 1.11–1.44). In contrast, the relationship between diastolic BP and cardiovascular risk remained U shaped irrespective of cardiovascular disease history or risk of subclinical disease. In conclusion, the lack of a clear association between systolic BP and cardiovascular risk in this population seems attributable to confounding, suggesting that more intensive systolic BP reduction may be beneficial in such patients.

    right posterior superior iliac spine and the femoral trochanter,and the level line of the right femoral trochanter.The explosion wave pressures were collected 10 cm away from the explosion point before they were converted to the hit point pressures by an equation in each group.The injury to the sacral plexus was assessed according to the short-latency somatosensory evoked potential (SLSEP) recorded at preinjury,immediately at injury and one week postinjury. Results The hit point pressures in groups A,B and C were respectively 413.25 ± 8.09 MPa,51.34 ± 1.03 MPa and 3.61 ± 7.50 MPa.The injury areas were respectively 31.47 ±5.91 cm2,18.13 ±8.04 cm2 and 4.60±7.16 cm2.There were significant between-group differences in hit point pressure and injury area( P < 0.05).The sacral plexus was ruptured in all animals and the one-week survival rate was 0 in group A.In group B the sacral plexus was obviously injured,the SLSEP disappeared immediately after injury and did not recover after one week,and the one-week survival rate was 83.3%.In group C,only the skin was hurt without injury to the sacral plexus,there was no significant difference in the changes of SLSEP between preinjury and postinjury ( P > 0.05),and the one-week survival rate was 100%. Conclusions A typical blast injury to the sacral plexus can be created with explosion equivalent of 600 mg TNT and a distance of 2 cm between the detonator and the hit point.Rabbit models made this way have a stable and long time survival for observation of pathological changes in the injured nerves of sacral plexus.

    The “reverse dipping” blood pressure (BP) pattern has been studied among the general population and in individuals suffering from hypertension. However, the prognosis of this pattern in chronic kidney disease (CKD) patients is not known. We monitored BP throughout the day and followed health outcomes in 588 CKD patients admitted to our hospital. Time to all-cause mortality, cardiovascular mortality, renal events and cardiovascular events was recorded. Multivariate-adjusted Cox regression analyses were carried out to detect the prognostic value of a reverse dipping BP pattern. Prevalence of a “dipper”, “non-dipper” and “reverse dippers” was 34.69%, 43.54% and 18.03%, respectively. Patients with a reverse dipping pattern had a higher prevalence of total mortality, cardiovascular mortality, renal events and cardiovascular events than patients with a dipping pattern (P < 0.025). Multivariate-adjusted Cox regression analyses showed that reverse dippers (versus dippers) were associated with a higher risk of total mortality (hazard ratio [HR], 5.08; 95% confidence interval [CI], 1.79~14.47), cardiovascular mortality (4.17; 1.25~13.88), renal events (3.00; 1.59~5.65) and cardiovascular events (4.12; 1.78~9.51) even after adjustment by 24-h systolic BP. These data suggest that a reverse dipping BP pattern, independent of 24-h levels of systolic BP, has prognostic value in CKD patients not undergoing dialysis. PMID:27713498

    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

    1. Properties of dorsal horn interneurones that process information from group II muscle afferents in the sacral segments of the spinal cord have been investigated in the cat using both intracellular and extracellular recording. 2. The interneurones were excited by group II muscle afferents and cutaneous afferents but not by group I muscle afferents. They were most effectively excited by group II afferents of the posterior biceps, semitendinosus, triceps surae and quadriceps muscle nerves and by cutaneous afferents running in the cutaneous femoris, pudendal and sural nerves. The earliest synaptic actions were evoked monosynaptically and were very tightly locked to the stimuli. 3. EPSPs evoked monosynaptically by group II muscle afferents and cutaneous afferents of the most effective nerves were often cut short by disynaptic IPSPs. As a consequence of this negative feedback the EPSPs gave rise to single or double spike potentials and only a minority of interneurones responded with repetitive discharges. However, the neurones that did respond repetitively did so at a very high frequency of discharges (0.8-1.2 ms intervals between the first 2-3 spikes). 4. Sacral dorsal horn group II interneurones do not appear to act directly upon motoneurones because: (i) these interneurones are located outside the area within which last order interneurones have previously been found and (ii) the latencies of PSPs evoked in motoneurones by stimulation of the posterior biceps and semitendinosus, cutaneous femoris and pudendal nerves (i.e. the main nerves providing input to sacral interneurones) are compatible with a tri- but not with a disynaptic coupling. Spatial facilitation of EPSPs and IPSPs following synchronous stimulation of group II and cutaneous afferents of these nerves shows, however, that sacral interneurones may induce excitation or inhibition of motoneurones via other interneurones. 5. Comparison of the properties of group II interneurones in the sacral segments with

    Full Text Available Objective: to analyze short-term outcomes and complications for our first fifty patients with fecal incontinence undergoing sacral root stimulation. Patients: fifty patients with fecal incontinence receiving sacral neuromodulation in 4 hospitals are reviewed. Discussed variables include: age, sex, incontinence duration, incontinence cause, prior surgery for incontinence, Wexner scale score, anorectal manometry parameters, and endoanal ultrasonographic findings. Following the procedure Wexner scale score, anorectal manometry parameters, and associated complications are reviewed. Results: mean age of patients is 59.9 years, with females predominating. Most common causes of incontinence include obstetric procedures, idiopathic origin, and prior anal surgery. Mean follow-up is 17.02 months. Follow-up revealed a statistically significant reduction in Wexner scale score and increase in voluntary anal pressure. Technique-derived minor complications included: 2 surgical wound infections that led to stimulator withdrawal; 2 patients with pain who were managed conservatively; 1 case of externalization in a gluteal stimulator; and 1 broken tetrapolar electrode. Conclusions: sacral nerve stimulation is a simple technique that improves Wexner scores in a statistically significant manner with a low complications rate.Objetivo: analizar los resultados y complicaciones a corto plazo de nuestros primeros cincuenta pacientes con incontinencia fecal tratados mediante estimulación de raíces sacras.

    The detrusor-sphincteric dyssynergia is analyzed by comparing the natural impulse patterns of secondary muscle spindle afferents (SP2) contributing to continence (SP2 fibre activity changes are similar to detrusor pressure changes) and sphincteric motoneurons in a brain-dead human with those in patients with spinal cord injuries. In the brain-dead the sphincteric motoneurons, subserving continence, were inhibited at a time, when preganglionic parasympathetic efferents and a SP2 fibre increased their activity (physiologic). In paraplegics the sphincteric motoneurons were not inhibited (pathophysiologic). In the brain-dead, an SP2 fibre showed doublet firing (interspike interval (II) 10 to 14 ms) for low level parasympathetic activation and multi-ending regular firing for high parasympathetic activation. In one paraplegic with strong bladder dysfunction, the multi-ending regular firing was replaced by a repeated burst firing with a shortest II of 0.2 ms (transmission frequency = 5000 Hz). The pathologic firing patterns of the SP2 fibres, the detrusor-sphincteric dyscoordination, and hyperreflexia in paraplegics are most likely a result of neuronal network changes in the parasympathetic and somatic nervous system divisions of the sacral micturition center after spinal cord injury. It is discussed that urinary bladder functions can be re-learned.

    Perineurial (Tarlov) cysts are meningeal dilations of the posterior spinal nerve root sheath that most often affect sacral roots and can cause a progressive painful radiculopathy. Tarlov cysts are most commonly diagnosed by lumbosacral magnetic resonance imaging and can often be demonstrated by computerized tomography myelography to communicate with the spinal subarachnoid space. The cyst can enlarge via a net inflow of cerebrospinal fluid, eventually causing symptoms by distorting, compressing, or stretching adjacent nerve roots. It is generally agreed that asymptomatic Tarlov cysts do not require treatment. When symptomatic, the potential surgery-related benefit and the specific surgical intervention remain controversial. The authors describe the clinical presentation, treatment, and results of surgical cyst fenestration, partial cyst wall resection, and myofascial flap repair and closure in a case of a symptomatic sacral Tarlov cyst. They review the medical literature, describe various theories on the origin and pathogenesis of Tarlov cysts, and assess alternative treatment strategies.

    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.)

    An unusual case of a sacral, extradural choroid plexus papilloma involving the S1-3 level is described. This 50-year-old woman presented with a 4-month history of pain involving her right buttock, perineum, and leg. Contrast-enhanced magnetic resonance (MR) imaging of the spine revealed a well-defined, mildly enhancing sacral canal mass at the S1-3 level; its appearance was consistent with that of a benign tumor. Intraoperatively, the lesion was found to be extradural in location and was entwined among nerve roots in the sacral canal. Microscopic examination of the gross totally resected tumor revealed typical features of a choroid plexus papilloma. Despite performing a thorough neuroimaging workup (craniospinal contrast-enhanced MR imaging) for an intracranial or spinal primary mass, none was found. The choroid plexus appeared entirely normal; however, both a cavum septum pellucidum and a cavum vergae were noted. Extraneural choroid plexus papilloma, specifically intrasacral, extradural choroid plexus papilloma has not been previously reported. The present example is thought to have arisen either from ectopic choroid plexus tissue or perhaps by metaplasia from ependymal rests.

    Full Text Available Abstract Introduction Sacral stress fractures are a rare but well known cause of low back pain. This type of fracture has also been observed as a postpartum complication. To date, no cases of intrapartum sacral stress fractures have been described in the literature. Case presentation We report the case of a 26-year-old Caucasian European primigravid patient (30 weeks and two days of gestation who presented to our outpatient clinic with severe low back pain that had started after a downhill walk 14 days previously. She had no history of trauma. A magnetic resonance imaging scan revealed a non-displaced stress fracture of the right lateral mass of her sacrum. Following her decision to opt for non-operative treatment, our patient received an epidural catheter for pain control. The remaining course of her pregnancy was uneventful and our patient gave birth to a healthy child by normal vaginal delivery. Conclusions We conclude that a sacral stress fracture must be considered as a possible cause of low back pain during pregnancy.

    Objective This study aims to investigate the surgical results of single-stage en bloc resections using a posterior approach for sacral tumors and evaluate its benefit for these tumors. Methods A total of 32 cases involving patients with sacral tumors who were treated with single-stage en bloc resection by posterior approach from April 2004 to January 2010 were reviewed. The patient cohort included 20 males and 12 females. The average patient age was 49.1 years old (range, 18 to 75 years old). Twenty-seven patients suf ered from primary sacral tumors, including 17 patients with chordomas, 5 patients with giant cel tumors of the bone, 3 patients with chondrosarcoma, 1 patient with sarcoma of the nerve fibers, and 1 patient with neurofibromatosis. Five patients were diagnosed with sacral metastatic tumors, including 2 cases of breast cancer, 1 case of renal carcinoma, 1 case of thyroid cancer, and 1 case of lung cancer. According to the Frankel grading system, there were 3 Grade B tumors, 4 Grade C tumors, 10 Grade D tumors, and 15 Grade E tumors. Results The operation took 265 min on average (range, 130–360 min), and blood loss was 1676 mL on average (range, 800–1800 mL) during the operation. The fol ow-up period ranged from 6 months to 6.2 years. Al patients had pain prior to operation. Twenty-eight patients experienced complete pain-relief, and 4 patients experienced partial pain-relief after their operations. In al patients, neurological function was improved more than one grade using the Frankel grading system. Up to now, 5 patients experienced local recurrence after operation, and 2 patients were deceased. The remaining patients are stil alive without recurrence. Conclusion Single-stage en bloc resection through a posterior approach for sacral tumors is feasible, safe, and ef ective. It has many advantages, such as control ing local recurrence, thorough decompression of the spinal cord, relieving pain, improving quality of life, and prolonging survival.

    This is a summary of a presentation made in the symposium "Improved Continuous Quality Care in Patients with Pressure Ulcers and Chronic Injuries", which was held in Toledo in 2009. A 76 year old woman had been assessed (she belonged to the age group that frequently suffers this condition). She lived in a social healthcare centre and had a III stage sacral pressure ulcer. Using Gordon's Functional Health Patterns for assessing "Acute pain", a nursing diagnosis is described and the nursing care plan has been presented according to NANDA, NIC, NOC taxonomy. The aim of this article is to show the importance of considering the pain in patients who suffer from this type of lesion, which, although almost always present, it is often undervalued by nursing staff, resulting in an even worse quality of life for the patient, due to both physical and psychological effects. This case shows how to assess pain in a patient with ulcers, and helps establish an individualised care plan with a priority on pain treatment and relief. As as result of the interventions carried out, a better perception of pain is achieved, thus helping to improve patient's mobility and night rest.

    Minimally invasive glaucoma surgery is a developing area that has the potential to replace traditional glaucoma surgery, with its known risk profile, but at present there are no randomised controlled data to validate its use. We report on a case where sequential bilateral combined ab interno trabeculotomy and lens extraction surgery was performed on a 45-year-old woman with combined uveitic and chronic narrow angle raised intraocular pressure. Maximal medical management alone could not control the intraocular pressure. At 12-month follow-up, the patient had achieved stable intraocular pressure in both eyes on a combination of topical ocular antiglaucomatous and steroid therapies. This case demonstrates the effectiveness of trabecular meshwork ablation via ab interno trabeculotomy in a case of complex mixed mechanism glaucoma.

    Full Text Available 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.

  2. The femoro-sacral posterior angle: an anatomical sagittal pelvic parameter usable with dome-shaped sacrum.

    2007-02-01

    The sagittal pelvic morphology modulates the individual alignment of the spine. Anatomical angular parameters were described as follows: the "Pelvic Incidence" (PI) and the Jackson's angle "Pelvic Lordosis" (PR-S1). Significant chains of relationships were expressed connecting these angles with pelvic and spinal positional parameters. This allows an individual assessment of the harmony of the sagittal spinal balance. But in case of spondylolysis with high-grade listhesis, the upper plate of the sacrum shows a dome-shaped deformity. The previous anatomical parameters are therefore imprecise. Indeed, the anterior part of the sacrum being inaccurate, an exact assessment of these angles becomes impossible. Therefore, we propose a new angular parameter named "Femoro-Sacral Posterior Angle" (FSPA): the angle between the posterior wall of the first sacral vertebra, always well definite, and the line connecting the posterior part of the sacral plate to the femoral axis. The validation of this parameter was performed and compared with the classical published parameters. It showed good inter-observer reliability, even with dome-shaped sacral plate. In spite of lower correlation with the positional parameters than those observed with PI or PR-S1, the FSPA appeared to be reliable and precise for an exact evaluation of the sagittal spino-pelvic balance is case of spondylo-listhesis with dome-shaped sacral endplate.

    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.

    Full Text Available 【Abstract】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.

    Two women, aged 50 and 67 years, with septic arthritis of the symphysis pubis attended by severe low back pain, were followed with CT and MR imaging of the pelvis, as well as bone scintigraphy in one patient. In the first patient sacral fractures with severe displacement were revealed, prompting stabilizing symphysiodesis. In the second patient an undisplaced fatigue fracture was confirmed in the right half of the sacrum. In patients with pelvic laxity following arthritis of the symphysis and post-traumatic osteolysis associated with low back pain, displaced or occult fractures of the bones adjacent to the sacroiliac joints should be considered.

    After colorectal and anorectal interventions for chronic inflammatory bowel diseases, specific complications can occur.In Crohn's disease these complications mainly occur after proctocolectomy. Pelvic sepsis can be prevented by omentoplasty with fixation inside the pelvis. A persisting sepsis of the sacral cavity can be treated primarily by dissection of the anal sphincter which ensures better drainage. In cases of chronic sacral sepsis, transposition of the gracilis muscle is a further effective option. Early recurrence of a transsphincteric anal fistula should be treated by reinsertion of a silicon seton drainage.Complications after restorative proctocolectomy are frequent and manifold (35%). The main acute complications are anastomotic leakage and pelvic sepsis. Therapy consists of transperineal drainage of the abscess with simultaneous transanal drainage. Late complications due to technical and septic reasons are still a relevant problem even 36 years after introduction of this operative technique. A consistent approach with detailed diagnostic and surgical therapy results in a 75% rescue rate of ileoanal pouches.

    2015-12-01

    Full Text Available Background: Compared to conventional therapies, sacral neuromodulation (SNM may offer an alternative, non-destructive treatment for SCI patients with bladder dysfunction. Understanding bladder response to SNM treatment for SCI in different phases may yield new insights for innovative use of this promising technique. Materials and Methods: Female Sprague-Dawley rats were used in this study to examine the effects of acute SNM on bladder reflex in complete SCI rats. All rats were anesthetized and set up for continuous saline infusion. Acute SNM treatment was implemented for about 6 hours for each rat. Cystometric parameters, including time between contractions, contraction duration, bladder peak pressure, and number of uninhibited contractions, were analyzed and compared within rats before and after SNM treatment. Results: For the spinally transected rats during early phase (less than two weeks post spinalization, the time between contractions and contraction duration both increased after SNM treatments, yet the increased amplitude was about or less than 20%. For the spinally transected rats with a longer days survival (about two to four weeks post spinalization, the time between contractions and contraction duration substantially increased after SNM treatment and the changes for their average values were more than 90%. For the spinally transected rats with a much longer days survival (more than five weeks post spinalization, the time between contractions and contraction duration increased after SNM treatments, yet the magnitude of changes were less than 30%. Conclusion: The present study suggested that the significant effectiveness of SNM for complete SCI played its role after the spinal shock phase and prior to the development of detrusor overactivity. It indicated that the time point of SNM treatment is necessary to be paid attention.

    Background: Transverse fractures of the sacrum are rare, and surgical treatment for these fractures ranges from conservative to challenging. Transverse stress fractures of the sacrum after placement of lumbar-to-sacral instrumentation have been previously described. We report a new technique to repair a transverse Type-2 Roy-Camille fracture with spondylolisthesis of S1 over S2 in a previously fused instrumented high-grade L4-L5, L5-S1 spondylolisthesis. Case Description: A 64-year-old female who previously had an L4-L5, L5-S1 fusion for spondylolisthesis presented with excruciating lower back pain and radiculopathy for over 6 months. She was found to have an S1-S2 transverse fracture caused by previous implantation of pedicle screws. She underwent repositioning of several failed right lumbar and sacral screws and then had bilateral S1-S2 screws placed directly across the fracture line. The patient had an unremarkable postoperative course. She discontinued most of her pain medications within 6 weeks postoperatively. In the months following surgery, she reported only minimal lower back pain and no radiculopathy with the last appointment 5 years postoperatively. Conclusions: We describe a novel technique to reduce an iatrogenic transverse type-2 Roy-Camille fracture at S1-S2 in a previously instrumented high-grade L4-L5, L5-S1 spondylolisthesis. The patient's fracture achieved adequate reduction and fusion with symptomatic relief. PMID:28028448

    The locking compression plate fixation treatment for the unstable sacral fractures is simple and effective, with less trauma and complications. Some locking compression plate parts have been made of high-strength Plate manufactured by hot stamping process since the demand for lightweight biomedical materials. Finite Element (FE) method of One-Step inverse forming based on deformation theory is the tool to evaluate the formability of locking compression plate panel quickly in initial design for reducing costs and development cycle of Plate. But current one-step inverse forming methods are all suitable for cold stamping, not hot-stamping. This paper proposed one-step inverse forming method and workflow for hot-stamping of locking compression Plate. And the B pillar of a sacral bone was simulated and its computing result was compared with experimental value. The result shows that the proposed method in this paper can quickly evaluate high temperature formability of high-strength Plate. And the method is proposed to be used in initial design.

    2015-01-01

    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.

    2013-07-01

    Reports from a United States cohort of chronic hemodialysis patients suggested that weight loss, a decline in pre-dialysis systolic blood pressure, and decreased serum albumin may precede death. However, no comparative studies have been reported in such patients from other countries. Here we analyzed dynamic changes in these parameters in hemodialysis patients and included 3593 individuals from 5 Asian countries; 35,146 from 18 European countries; 8649 from Argentina; and 4742 from the United States. In surviving prevalent patients, these variables appeared to have notably different dynamics than in patients who died. While in all populations the interdialytic weight gain, systolic blood pressure, and serum albumin levels were stable in surviving patients, these indicators declined starting more than a year ahead in those who died with the dynamics similar irrespective of gender and geographic region. In European patients, C-reactive protein levels were available on a routine basis and indicated that levels of this acute-phase protein were low and stable in surviving patients but rose sharply before death. Thus, relevant fundamental biological processes start many months before death in the majority of chronic hemodialysis patients. Longitudinal monitoring of these dynamics may help to identify patients at risk and aid the development of an alert system to initiate timely interventions to improve outcomes.

    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.

    Full Text Available Recent studies reported altered DNA methylation in failing human hearts. This may suggest a role for de novo DNA methylation in the development of heart failure. Here, we tested whether cardiomyocyte-specific loss of de novo DNA methyltransferases Dnmt3a and Dnmt3b altered cardiac function and remodeling after chronic left ventricular pressure overload.Mice with specific ablation of Dnmt3a and Dnmt3b expression in cardiomyocytes were generated by crossing floxed Dnmt3afl and Dnmt3bfl alleles with mice expressing Cre recombinase under control of the atrial myosin light chain gene promoter. The efficacy of combined Dnmt3a/3b ablation (DKO was characterized on cardiomyocyte-specific genomic DNA and mRNA levels. Cardiac phenotyping was carried out without (sham or with left ventricular pressure overload induced by transverse aortic constriction (TAC. Under similar conditions, cardiac genome-wide transcriptional profiling was performed and DNA methylation levels of promoters of differentially regulated genes were assessed by pyrosequencing.DKO cardiomyocytes showed virtual absence of targeted Dnmt3a and Dnmt3b mRNA transcripts. Cardiac phenotyping revealed no significant differences between DKO and control mice under sham and TAC conditions. Transcriptome analyses identified upregulation of 44 and downregulation of 9 genes in DKO as compared with control sham mice. TAC mice showed similar changes with substantial overlap of regulated genes compared to sham. Promoters of upregulated genes were largely unmethylated in DKO compared to control mice.The absence of cardiac pathology in the presence of the predicted molecular phenotype suggests that de novo DNA methylation in cardiomyocytes is dispensable for adaptive mechanisms after chronic cardiac pressure overload.

    Purpose To investigate the influence of sacral slope on the correlation between measurements of lumbar lordosis obtained by standing radiographs and magnetic resonance images in supine position (MRI). Little information is available on the correlation between measurements of lumbar lordosis obtained by radiographic and MR images. Most relevant studies have shown correlations for the thoracic spine, but detailed analyses on the lumbar spine are lacking. Methods MR images and standing lateral radiographs of 63 patients without actual low back pain or radiographic pathologies of the lumbar spine were analyzed. Standing radiographic measurements included the sagittal parameters pelvic incidence (PI) pelvic tilt (PT), and sacral slope (SS); MR images were used to additionally measure lumbar L1-S1 lordosis and single level lordosis. Differences between radiographic and MRI measurements were analyzed and divided into 4 subgroups of different sacral slope according to Roussouly's classification. Results Global lumbar lordosis (L1-S1) was 44.99° (± 10 754) on radiographs and 47.91° (± 9.170) on MRI, yielding a clinically relevant correlation (r = 0.61, p consideration of the Sacral Slope.

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

    The present study aimed to assess a posterior approach for the surgical resection of giant sacral neurogenic tumors, and to evaluate the oncological and functional outcomes. A total of 16 patients with giant sacral neurogenic tumors underwent pre-operative embolization and subsequent posterior sacral resection between January 2000 and June 2010. Benign tumors were identified in 12 cases, while four cases exhibited malignant peripheral nerve sheath tumors (MPNSTs). An evaluation of the operative techniques used, the level of blood loss, any complications and the functional and oncological outcomes was performed. All tumor masses were removed completely without intra-operative shock or fatalities. The mean tumor size was 17.5 cm (range, 11.5-28 cm) at the greatest diameter. The average level of intra-operative blood loss was 1,293 ml (range, 400-4,500 ml). Wound complications occurred in four patients (25%), including three cases of cutaneous necrosis and one wound infection. The mean follow-up time was 59 months (range, 24-110 months). Tumor recurrence or patient mortality as a result of the disease did not occur in any of the patients with benign sacral neurogenic tumors. The survival rate of the patients with malignant lesions was 75% (3/4 patients) since 25 % (1/4 patients) had multiple local recurrences and succumbed to the disease. The patients with benign tumors scored an average of 92.8% on the Musculoskeletal Tumor Society (MSTS) score functional evaluation, while the patients with malignant tumors scored an average of 60.3%. A posterior approach for the surgical resection of giant sacral neurogenic tumors, combined with pre-operative embolization may be safely conducted with satisfactory oncological and functional outcomes.

    Lumbar epidurography serves as an important radiographic procedure in the evaluation of patients with equivocal myelography and confusing or non-diagnostic physical findings. It is particularly valuable in patients with a wide ventral epidural space secondary to previous surgery, arachnoiditis or on a congenital basis. Several techniques and various contrast agents have been employed for the procedure. A pure Seldinger technique with a caudal approach through the sacral hiatus and injection of metrizamide gives excellent visualization of the epidural space and nerve root sleeves. The proper concentration of metrizamide is crucial for optimal results. Lateral, AP, and AP oblique radiographs, occasionally combined with lateral, complex motion tomography, clearly demonstrate the root sleeves and ventral epidural space. CT scanning, with present technology, does not provide the necessary detail for evaluating the epidural space.

    We describe the case of a 67-year-old woman with L5-S1 ontogenetic spondylolisthesis treated with pedicle fixation associated with interbody arthrodesis performed with S1-L5 trans-sacral screwing according to the technique of Bartolozzi. The procedure was followed by a wide decompressive laminectomy. The patient had a progressive improvement of the symptoms which gradually disappeared in 12 mo. The radiograph at 6 and 12 mo showed complete fusion system. The choice of treatment in L5-S1 ontogenetic spondylolithesis is related to a correct clinical and diagnostic planning (X-ray, computer tomography magnetic resonance imaging, Measurement). In particular, the severity index and the square of unstable zone, and the standard measurements already described in the literature, are important to understand and to plane the correct surgical strategy, that require, in most of the times, fusion and interbody artrodesis.

    Whether long-term blood pressure (BP) variability among individuals without diabetes mellitus is associated with new-onset chronic kidney disease (CKD) risk, independently of other BP parameters (eg, mean BP, cumulative exposure to BP) and metabolic profile changes during follow-up, remains uncertain. We used data from a nationwide study of 48 587 Japanese adults aged 40 to 74 years (mean age, 61.7 years; 39% men) without diabetes mellitus or CKD (estimated glomerular filtration rate diabetes mellitus, long-term BP variability during 3 years was associated with new-onset CKD risk, independently of mean or cumulative exposure to BP and metabolic profile changes during follow-up.

    Stress fractures occur in normal bone due to mechanical overload by cyclic stress increasing the osteoclastic activity, thus facilitating weakening leading to fracture of bones. Long-distance running may lead to stress fractures of the mid- and distal tibia and of the metatarsal bones. Stress fractures to the sacrum are rare. Certain factors for stress fractures in runners have been identified, such as leg-length inequality, a high longitudinal arch of the foot, forefoot varus, and menstrual irregularities in case of female athlete triad. We report on a 22-year-old female runner (usually training 140 km/week) suffering a sacral fatigue-type fracture. The female athlete triad with eating disorders, dysmenorrhea, and osteopenia was ruled out. Sexual hormone blood samples proofed normal values. The diagnosis was performed using magnetic resonance imaging 2 weeks after the onset of buttock pain. A conservative treatment regimen was initiated with strict physical rest for the first 2 weeks, and then gradual increase of physical activity with 60-90 min of daily cycling and moderate 2 x 60 min cross-training. After another 2 weeks time, daily 60-90 min of walking, Nordic pole walking, and moderate strength training two times a week was performed. At 7 weeks running was started, gradually increased to 90 km/week without any pain. A rapid rehabilitation programme after sacral stress fractures involving low impact physical activity, such as Walking and Nordic pole walking, is applicable to female athletes after ruling out the female athlete triad.

    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.)

    We investigated acute and chronic effects of CB1 cannabinoid receptor blockade in renin-angiotensin system-dependent hypertension using rimonabant (SR141716A), an orally active antagonist with central and peripheral actions. In transgenic (mRen2)27 rats, a model of angiotensin II-dependent hypertension with increased body mass and insulin resistance, acute systemic blockade of CB1 receptors significantly reduced blood pressure within 90 min but had no effect in Sprague-Dawley rats. No changes in metabolic hormones occurred with the acute treatment. During chronic CB1 receptor blockade, (mRen2)27 rats received daily oral administration of SR141716A (10 mg/kg/day) for 28 days. Systolic blood pressure was significantly reduced within 24 h, and at Day 21 of treatment values were 173 mmHg in vehicle versus 149 mmHg in drug-treated rats (P < 0.01). This accompanied lower cumulative weight gain (22 vs. 42 g vehicle; P < 0.001), fat mass (2.0 vs. 2.9% of body weight; P < 0.05), and serum leptin (2.8 vs. 6.0 ng/mL; P < 0.05) and insulin (1.0 vs. 1.9 ng/mL; P < 0.01), following an initial transient decrease in food consumption. Conscious hemodynamic recordings indicate twofold increases occurred in spontaneous baroreflex sensitivity (P < 0.05) and heart rate variability (P < 0.01), measures of cardiac vagal tone. The beneficial actions of CB1 receptor blockade in (mRen2)27 rats support the interpretation that an upregulated endocannabinoid system contributes to hypertension and impaired autonomic function in this angiotensin II-dependent model. We conclude that systemic CB1 receptor blockade may be an effective therapy for angiotensin II-dependent hypertension and associated metabolic syndrome.

    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.

    Sleep apnea is associated with hypertension. The mechanisms contributing to a sustained increase in mean arterial pressure (MAP) even during normoxic awake-state remain unknown. Rats exposed to chronic intermittent hypoxia for 7 days, a model of the hypoxemia associated with sleep apnea, exhibit sustained increases in MAP even during the normoxic dark phase. Activation of the renin-angiotensin system (RAS) has been implicated in chronic intermittent hypoxia (CIH) hypertension. Since the subfornical organ (SFO) serves as a primary target for the central actions of circulating ANG II, we tested the effects of ANG II type 1a receptor (AT1aR) knockdown in the SFO on the sustained increase in MAP in this CIH model. Adeno-associated virus carrying green fluorescent protein (GFP) and small-hairpin RNA against either AT1aR or a scrambled control sequence (SCM) was stereotaxically injected in the SFO of rats. After recovery, MAP, heart rate, respiratory rate, and activity were continuously recorded using radiotelemetry. In the normoxic groups, the recorded variables did not deviate from the baseline values. Both CIH groups exhibited significant increases in MAP during CIH exposures (P SCM-injected group exhibited a sustained increase in MAP (P SCM-CIH group. Our data indicate that AT1aRs in the SFO are critical for the sustained elevation in MAP and increased FosB/ΔFosB expression in forebrain autonomic nuclei associated with CIH.

    In twenty patients with COPD, the following pulmonary function test values were obtained (mean +- SD): FEV/sub 1.0/ = 1070 +- 490 ml;FEV/sub 1.0/ % = 47.7 +- 8.9 %;PaO/sub 2/ = 65.8 +- 8.4 torr;PaCO/sub 2/ = 39.7 +- 4.4 torr. All patients underwent right heart catheterization and pulmonary arterial mean pressures (PAMP) were obtained. The PAMP value was 20.2 +- 4.1 torr (range 12 - 28), RVEF was 52.2 +- 8.4 % (range 31 - 63) and RVRFR was 25.5 +- 4.7 %100 msec (range 18 - 34). The PAMP negatively correlated with the RVEF (r = -0.69, p < 0.001) and RVRFR (r = -0.82, p < 0.001). In ten healthy male subjects, the RVEF was 56.6 +- 5.1 % (range 50 - 64) and RVRFR was 37.7 +- 3.0 %100 msec (range 33 - 42). The lower limit of normal for the RVEF was regarded as 46.4 % and that of the RVRFR as 31.7 %100 msec;these are the values two standard deviations below the means. Nine of the twenty patients has a PAMP value of more than 20 torr (the sine qua non of cor pulmonale). Five of these nine patients had RVEF values less than 46.4 % and all of them had RVRFR values of less than 31.7 %100 msec. On the other hand, all of the remaining eleven patients (PAMP 20 torr or less) had RVEF values within the normal range, but ten of the eleven had RVRFR values of less than 31.7 %100 msec. Therefore, the RVRFR value, which showed excellent correlation with the PAMP, provided a noninvasive assessment of pulmonary arterial pressure with good sensitivity in detecting elevated pressure. The RVEF value supplemented the RVRFR with good specificity for detection of elevation of pressure;that is, it eliminated false positive results. (J.P.N.)

    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.

    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.

    Older and even new antidepressants cause adverse effects, such as orthostatic hypotension, hyper- or hypoglycemia, liver injury or lipid disorders. In our previous experiments we showed significant antidepressant- and anxiolytic-like activities of dual 5-HT1A and 5-HT7 antagonists with α1-adrenolitic properties i.e. 1-[(2,6-dimethylphenoxy)ethoxyethyl]-4-(2-methoxyphenyl)piperazine hydrochloride (HBK-14) and 1-[(2-chloro-6-methylphenoxy)ethoxyethyl]-4-(2-methoxyphenyl)piperazine hydrochloride (HBK-15). Here, we evaluated the influence of chronic administration of HBK-14 and HBK-15 on blood pressure (non-invasive blood pressure measurement system for rodents), lipid profile (total cholesterol, low density lipoproteins—LDL, high density lipoproteins—HDL, triglycerides), glucose level, and liver enzymes activity (aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transferase). We determined potential antihistaminic (isolated guinea pig ileum) and antioxidant properties (ferric reducing ability of plasma–FRAP, non-protein thiols–NPSH, stable free radical diphenylpicrylhydrazyl—DPPH) cytotoxicity. Our experiments revealed that HBK-14 and HBK-15 did not influence blood pressure, lipid profile, glucose level or liver enzymes activity in rats after 2-week treatment. We also showed that none of the compounds possessed antioxidant or cytotoxic properties at antidepressant- and anxiolytic-like doses. HBK-14 and HBK-15 very weakly blocked H1 receptors in guinea pig ileum. Positive results of our preliminary experiments on the safety of HBK-14 and HBK-15 encourage further studies concerning their effectiveness in the treatment of depression and/or anxiety disorders.

    Full Text Available In this study we investigated sensorimotor processing of painful pressure stimulation on the lower back of patients with chronic lower back pain (CLBP by using functional near-infrared spectroscopy (fNIRS to measure changes in cerebral hemodynamics and oxygenation. The main objectives were whether patients with CLBP show different relative changes in oxy- and deoxyhemoglobin (O2Hb and HHb in the supplementary motor area (SMA and primary somatosensory cortex (S1 compared to healthy controls (HC. Twelve patients with CLBP (32 ± 6.1 years; range: 24 – 44 years; 9 women and twenty HCs (33.5 ± 10.7 years; range 22-61 years; 8 women participated in the study. Painful and non-painful pressure stimulation was exerted with a thumb grip perpendicularly to the spinous process of the lumbar spine. A force sensor was attached at the spinous process in order control for pressure forces. Tactile stimulation was realized by a one-finger brushing. Hemodynamic changes in the SMA and S1 were measured bilaterally using a multi-channel continuous wave fNIRS imaging system and a multi-distant probe array. Patients with CLBP showed significant stimulus-evoked hemodynamic responses in O2Hb only in the right S1, while the healthy controls exhibited significant O2Hb changes bilaterally in both, SMA and S1. However, the group comparisons revealed no significant different hemodynamic responses in O2Hb and HHb in the SMA and S1 after both pressure stimulations. This non-significant result might be driven by the high inter-subject variability of hemodynamic responses that has been observed within the patients group. In conclusion, we could not find different stimulus-evoked hemodynamic responses in patients with CLBP compared to HCs. This indicates that neither S1 nor the SMA show a specificity for CLBP during pressure stimulation on the lower back. However, the results point to a potential subgrouping regarding task-related cortical activity within the CLBP group; a

However, the group comparisons revealed no significant different hemodynamic responses in [O2Hb] and [HHb] in the SMA and S1 after both pressure stimulations. This non-significant result might be driven by the high inter-subject variability of hemodynamic responses that has been observed within the patients group. In conclusion, we could not find different stimulus-evoked hemodynamic responses in patients with CLBP compared to HCs. This indicates that neither S1 nor the SMA show a specificity for CLBP during pressure stimulation on the lower back. However, the results point to a potential subgrouping regarding task-related cortical activity within the CLBP group; a finding worth

    To assess the role of the renin-angiotensin (RA) system in the development of cold-induced hypertension in rats, systolic blood pressure (SBP), plasma renin activity (PRA), and the dipsogenic responsiveness to s.c. administration of angiotensin II (AII) were measured weekly for 4 weeks. SBP increased significantly during the third week of exposure to cold (5C), compared to warm-adapted controls. A significant increase in SBP occurred during the third week of cold. In contrast, (PRA) increased within the first week of cold, and declined thereafter to reach the level of the control by the third week. By the fourth week, PRA decreased to a level significantly below that of control. The dipsogenic responsiveness to acute administration of AII increased significantly by the third week of cold and remained significantly elevated during the fourth week. There was a significant direct relationship between dipsogenic responsiveness to AII and SBP in the cold-treated but not the control group. There was also a significant indirect linear relationship between PRA and dipsogenic responsiveness to AII. Cold-treated rats had significant increases in urinary norepinephrine output and weights of heart, kidneys, adrenals, and brown adipose tissue. Thus, the results suggest, but do not prove, either that the elevation of blood pressure under these conditions may be induced by changes in the RA system. The results suggest further that the reduction in the drinking response to AII accompanying increases in PRA may be related to changes in the regulation of central receptors for AII.

    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.

    Resistance training has been recommended for maintenance or improvement of the functional health of older adults, but its effect on acute cardiovascular responses remains unclear. Thus, the purpose of this study was to analyze the effect of 12 weeks of resistance training on post-exercise blood pressure (BP) in normotensive older women. Twenty-eight normotensive and physically inactive women (≥ 60 years) were randomly assigned to a training group (TG) or a control group (CG). The TG underwent a resistance training program (12 weeks, 8 exercises, 2 sets, 10-15 repetitions, 3 days/week), while the CG performed stretching exercises (12 weeks, 2 sets, 20 s each, 2 days/week). At baseline and after the intervention, participants were randomly submitted to two experimental sessions: a resistance exercise session (7 exercises, 2 sets, 10-15 repetitions) and a control session. BP was obtained pre- and post-sessions (90 min), through auscultation. Post-exercise hypotension was observed for systolic, diastolic, and mean BP in the TG (-6.1, -3.4, and -4.3 mmHg, respectively; P post-exercise BP and 12 weeks of resistance training program do not change the occurrence or magnitude of this hypotension.

    The response of right ventricular ejection fraction (RVEF) and right ventricular end-diastolic volume (RVEDV) to exercise was studied in 11 patients with severe (FEV/sub 25/sub(%)sub(-)/sub 75/sub(%)=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, P<0.01). Two of the 11 COPD patients had a RVEF during rest that was below lower limits, while 10 of 11 patients had RV dilation. Right ventricular end-diastolic pressure, measured during rest in patients with COPD, was normal (6.1+-2.1 mm Hg) and cardiac index was within normal limits (3.55+-0.82 l/min/m/sup 2/). With exercise this cardiac index rose to 5.52+-1.7/min/m/sup 2/(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.

  6. Vascular endothelium derived endothelin-1 is required for normal heart function after chronic pressure overload in mice.

    Full Text Available BACKGROUND: Endothelin-1 participates in the pathophysiology of heart failure. The reasons for the lack of beneficial effect of endothelin antagonists in heart failure patients remain however speculative. The anti-apoptotic properties of ET-1 on cardiomyocytes could be a reasonable explanation. We therefore hypothesized that blocking the pro-apoptotic TNF-α pathway using pentoxifylline could prevent the deleterious effect of the lack of ET-1 in a model for heart failure. METHODS: We performed transaortic constriction (TAC in vascular endothelial cells specific ET-1 deficient (VEETKO and wild type (WT mice (n = 5-9 and treated them with pentoxifylline for twelve weeks. RESULTS: TAC induced a cardiac hypertrophy in VEETKO and WT mice but a reduction of fractional shortening could be detected by echocardiography in VEETKO mice only. Cardiomyocyte diameter was significantly increased by TAC in VEETKO mice only. Pentoxifylline treatment prevented cardiac hypertrophy and reduction of fractional shortening in VEETKO mice but decreased fractional shortening in WT mice. Collagen deposition and number of apoptotic cells remained stable between the groups as did TNF-α, caspase-3 and caspase-8 messenger RNA expression levels. TAC surgery enhanced ANP, BNP and bcl2 expression. Pentoxifylline treatment reduced expression levels of BNP, bcl2 and bax. CONCLUSIONS: Lack of endothelial ET-1 worsened the impact of TAC-induced pressure overload on cardiac function, indicating the crucial role of ET-1 for normal cardiac function under stress. Moreover, we put in light a TNF-α-independent beneficial effect of pentoxifylline in the VEETKO mice suggesting a therapeutic potential for pentoxifylline in a subpopulation of heart failure patients at higher risk.

    Many published prospective trials have reported clinically meaningful morning-evening, treatment-time differences in the blood pressure (BP)-lowering efficacy, duration of action, and safety of most classes of hypertension medications. Most important, it was recently documented that routine ingestion of the full daily dose of ≥1 hypertension medications at bedtime, compared with ingestion of all of them upon awakening, significantly reduces cardiovascular disease (CVD) events. Nocturnal hypertension and non-dipping (hypertension treatment time on the circadian BP pattern and degree of BP control of hypertensive patients with CKD evaluated by 48-h ABPM. This cross-sectional study evaluated 2659 such patients (1585 men/1074 women), 64.9 ± 13.2 (mean ± SD) yrs of age, enrolled in the Hygia Project, involving primary care centers of northwest Spain and designed to evaluate prospectively CVD risk by ABPM; 1446 were ingesting all BP-lowering medications upon awakening, whereas 1213 patients were ingesting ≥1 medications at bedtime. Among the latter, 359 patients were ingesting all medications at bedtime, whereas 854 were ingesting the full daily dose of some medications upon awakening and the others at bedtime. Those ingesting all medications upon awakening had significantly higher total cholesterol and low-density lipoprotein (LDL) cholesterol than those ingesting ≥1 medications at bedtime. Moreover, patients ingesting all medications at bedtime had the lowest fasting glucose, serum creatinine, and uric acid. Ingestion of ≥1 medications at bedtime was significantly associated with lower asleep systolic (SBP) and diastolic (DBP) BP means than treatment with all medications upon awakening. The sleep-time relative SBP decline was significantly attenuated in patients ingesting all medications upon awakening (p hypertension medications were ingested upon awakening (68.3%) than when ≥1 of them was ingested at bedtime (54.2%; p hypertension medications

However, its therapeutic effect remains undefined due to the unclear nature of diaphragmatic mobilization during IMT. Diaphragmatic mobilization, represented by transdiaphragmatic pressure (Pdi, and neural respiratory drive, expressed as the corrected root mean square (RMS of the diaphragmatic electromyogram (EMGdi, both provide vital information to select the proper IMT device and loads in COPD, therefore contributing to the curative effect of IMT. Pdi and RMS of EMGdi (RMSdi% were measured and compared during inspiratory resistive training and threshold load training in stable patients with COPD.Patients and methods: Pdi and neural respiratory drive were measured continuously during inspiratory resistive training and threshold load training in 12 stable patients with COPD (forced expiratory volume in 1 s ± SD was 26.1%±10.2% predicted.Results: Pdi was significantly higher during high-intensity threshold load training (91.46±17.24 cmH2O than during inspiratory resistive training (27.24±6.13 cmH2O in stable patients with COPD, with P<0.01 for each. Significant difference was also found in RMSdi% between high-intensity threshold load training and inspiratory resistive training (69.98%±16.78% vs 17.26%±14.65%, P<0.01.Conclusion: We concluded that threshold load training shows greater mobilization of Pdi and neural respiratory drive than inspiratory resistive training in stable patients with COPD.

    Full Text Available Abstract Background Despite evidence implicating dietary sodium in the pathogenesis of cardiovascular disease (CVD in chronic kidney disease (CKD, quality intervention trials in CKD patients are lacking. This study aims to investigate the effect of reducing sodium intake on blood pressure, risk factors for progression of CKD and other cardiovascular risk factors in CKD. Methods/design The LowSALT CKD study is a six week randomized-crossover trial assessing the effect of a moderate (180 mmol/day compared with a low (60 mmol/day sodium intake on cardiovascular risk factors and risk factors for kidney function decline in mild-moderate CKD (stage III-IV. The primary outcome of interest is 24-hour ambulatory blood pressure, with secondary outcomes including arterial stiffness (pulse wave velocity, proteinuria and fluid status. The randomized crossover trial (Phase 1 is supported by an ancillary trial (Phase 2 of longitudinal-observational design to assess the longer term effectiveness of sodium restriction. Phase 2 will continue measurement of outcomes as per Phase 1, with the addition of patient-centered outcomes, such as dietary adherence to sodium restriction (degree of adherence and barriers/enablers, quality of life and taste assessment. Discussion The LowSALT CKD study is an investigator-initiated study specifically designed to assess the proof-of-concept and efficacy of sodium restriction in patients with established CKD. Phase 2 will assess the longer term effectiveness of sodium restriction in the same participants, enhancing the translation of Phase 1 results into practice. This trial will provide much-needed insight into sodium restriction as a treatment option to reduce risk of CVD and CKD progression in CKD patients.

    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.

    Full Text Available An altered ambulatory blood pressure (BP and heart rate (HR profile is related to chronic kidney disease (CKD and cardiorenal syndrome. In this study, we examined the effects of aliskiren, when added to angiotensin II type 1 receptor blockers, on ambulatory BP and cardiorenal function in CKD. Thirty-six hypertensive CKD patients were randomly assigned to the aliskiren add-on group (n = 18 or the benazepril add-on group (n = 18. Ambulatory BP and cardiorenal function parameters were measured at baseline and 24 weeks after treatment. Compared with the benazepril group, nighttime systolic BP variability in the aliskiren group was lower after treatment. Albuminuria was decreased in the aliskiren group, but not in the benazepril group. In addition, left ventricular mass index (LVMI was significantly lower in the aliskiren group than in the benazepril group after treatment. In the aliskiren group, multivariate linear regression analysis showed an association between changes in albuminuria and changes in nighttime systolic BP. Furthermore, there were associations between changes in LVMI and changes in daytime HR variability, as well as between changes in LVMI and changes in plasma aldosterone concentration. These results suggest that aliskiren add-on therapy may be beneficial for suppression of renal deterioration and pathological cardiac remodeling through an improvement that is effected in ambulatory BP and HR profiles.

    Neurological complications of AH1N1 vaccination such as Guillain-Barré syndrome were described in the previous years. Several reports suggest that hereditary neuropathies may be a predisposing factor for immune-mediated neuropathies. We report the case of a 54-year-old female who developed chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) 5 weeks after AH1N1 vaccination. She had no previous neurological history, but neurophysiological features led us to suspect an underlying hereditary neuropathy. PMP22 gene analysis showed a typical deletion, confirming the diagnosis of hereditary neuropathy with liability to pressure palsies (HNPP). We observed a significant clinical and neurophysiological improvement of the neuropathy after intravenous immunoglobulin treatment. This is, to our knowledge, the first reported case of CIDP potentially triggered by AH1N1 vaccination. This and previous observations suggest that genetic-determined neuropathies could predispose to the occurrence of immune-mediated neuropathies. One must recall the possibility of a superimposed hereditary neuropathy like HNPP in patients with a clinical presentation of CIDP, especially when positive family history or unexpected neurophysiological features are present.

    [Purpose] This study was performed to assess the influence of applying dual pressure biofeedback units (DPBUs) on the angle of pelvic rotation and abdominal muscle activity during the active straight leg raise (ASLR). [Subjects] Seventeen patients with low-back pain (LBP) participated in this study. [Methods] The subjects were asked to perform an active straight leg raise (ASLR) without a PBU, with a single PBU, and with DPBUs. The angles of pelvic rotation were measured using a three-dimensional motion-analysis system, and the muscle activity of the bilateral internal oblique abdominis (IO), external oblique abdominis (EO), and rectus abdominis (RA) was recorded using surface electromyography (EMG). One-way repeated-measures ANOVA was performed to determine the rotation angles and muscle activity under the three conditions. [Results] The EMG activity of the ipsilateral IO, contralateral EO, and bilateral RA was greater and pelvic rotation was lower with the DPBUs than with no PBU or a single PBU. [Conclusion] The results of this study suggest that applying DPBUs during ASLR is effective in decreasing unwanted pelvic rotation and increasing abdominal muscle activity in women with chronic low back pain.

    Scavenger receptor CD36 participates in lipid metabolism and inflammatory pathways important for cardiovascular disease and chronic kidney disease (CKD). Few pharmacological agents are available to slow the progression of CKD. However, apolipoprotein A-I-mimetic peptide 5A antagonizes CD36 in vitro. To test the efficacy of 5A, and to test the role of CD36 during CKD, we compared wild-type to CD36 knockout mice and wild-type mice treated with 5A, in a progressive CKD model that resembles human disease. Knockout and 5A-treated wild-type mice were protected from CKD progression without changes in blood pressure and had reductions in cardiovascular risk surrogate markers that are associated with CKD. Treatment with 5A did not further protect CD36 knockout mice from CKD progression, implicating CD36 as its main site of action. In a separate model of kidney fibrosis, 5A-treated wild-type mice had less macrophage infiltration and interstitial fibrosis. Peptide 5A exerted anti-inflammatory effects in the kidney and decreased renal expression of inflammasome genes. Thus, CD36 is a new therapeutic target for CKD and its associated cardiovascular risk factors. Peptide 5A may be a promising new agent to slow CKD progression.

    Noise-induced hearing disorders are a significant public health concern. One cause of such disorders is exposure to high sound pressure levels (SPLs) above 85 dBA for eight hours/day. High SPL exposures occur in occupational and recreational settings and affect a substantial proportion of the population. However, an even larger proportion is exposed to more moderate SPLs for longer durations. Therefore, there is significant need to better understand the impact of chronic, moderate SPL exposures on auditory processing, especially in the absence of hearing loss. In this study, we applied functional magnetic resonance imaging (fMRI) with tonal acoustic stimulation on an established broadband rat exposure model (65 dB SPL, 30 kHz low-pass, 60 days). The auditory midbrain response of exposed subjects to 7 kHz stimulation (within exposure bandwidth) shifts dorsolaterally to regions that typically respond to lower stimulation frequencies. This shift is quantified by a region of interest analysis that shows that fMRI signals are higher in the dorsolateral midbrain of exposed subjects and in the ventromedial midbrain of control subjects (pmidbrain regions above the exposure bandwidth spatially expand due to exposure. This expansion shifts lower frequency regions dorsolaterally. Similar observations have previously been made in the rat auditory cortex. Therefore, moderate SPL exposures affect auditory processing at multiple levels, from the auditory cortex to the midbrain.

    2013-04-01

    Full Text Available Objectives: Diabetes related vascular complications of the lower extremity could be classified as micro- and macrovascular. Ankle-brachial index (ABI and toe blood pressure (TBP measurements evaluate macro-circulation, whereas transcutaneous oximetry (TcPO2 is considered to be a composite measure of vascular function, thereby also reflecting microcirculation. Microvascular disease in the eye involves abnormal capillary permeability and possibly thereby increased macular thickness. The aim of the present clinical study was to evaluate if microvascular disease in the eye was related to measures of foot ischemia in patients with diabetes mellitus. Methods: Twenty consecutive patients with diabetes and chronic full-thickness foot ulcers were included. Peripheral ischemia was diagnosed using TcPO2, TBP and ABI. Macular thickness was measured with optical coherence tomography technique. Results: Based on TcPO2, TBP and ABI measurements 14, 13 and 13 patients, respectively, were classified as ischemic. Patients with ischemic TcPO2 levels at the dorsum of the foot had significantly higher macular thicknesses. This was not the case in patients with ischemic TBP or ABI levels. Conclusion: TcPO2, unlike TBP and ABI, seems to be a clinically relevant measure of peripheral microvascular disease in patients with diabetes mellitus and may, if low, indicate an increased risk of macular edema.

    Objective To analyze the postoperative complications of sacral tumor and treatment strategy. Methods This retrospective study included 38 cases of sacral tumors surgically treated from December 2003 to December 2010. The age of patients ranged from 18 to 65 years (mean 34.5 years) , including of 22 male and 16 female. Record the most common postoperative complication of these patients, causes and relative treatments were analyzed. Results After surgery, 26 cases were followed up for an average period of 3.1 years ( longest 5 years, shortest 10 months). None of the patients died in surgery. The early complications after surgery included gastrointestinal dysfunction in 31 cases. Nonunion of the incision occurred in 2 cases caused by radiation, one case with S4 tumor died of chronic infection after 8 monthes in spite of half year dressing, and the other was delayed union of the incision and the wound healed by dressing with granulation promoting plaster after 3 monthes. Incisal effuscin with hyperpyrexia happened in 3 cases. Enterococcal infection was confirmed by germiculture. Body temperature restored normally after 5-10 d with a method of puncture drainage and the application of vancomycin. Urine retention occurred in 2 cased after surgery and catheter removed after 3 monthes. Internal fixation( iliac screw) loosened in 3 cases during follow-up phase. Conclusion Because of stimulating bowel with effuscin and operation,gastrointestinal dysfunction in patients with sacral tumor rate is higher, but alleviated commonly. Sacral tumor patients with a higher incidence of enterococcal infection caused by differential tissue coverage and near perineum. The treatment of enterococcal infection is difficult. Be cautious about operating on patients after radiation. Selective nerve root should be preserved to avoid urine retention.%目的 探讨骶骨肿瘤术后常见并发症及其处理方法.方法 2003年12月~2010年12月间手术治疗的38

    Central blood pressure (BP) can be assessed noninvasively based on radial tonometry and may potentially be a better predictor of clinical outcome than brachial BP. However, the validity of noninvasively obtained estimates has never been examined in patients with chronic kidney disease (CKD). Here we compared invasive aortic systolic BP (SBP) with estimated central SBP obtained by radial artery tonometry and examined the influence of renal function and arterial stiffness on this relationship. We evaluated 83 patients with stage 3 to 5 CKD (mean estimated glomerular filtration rate [eGFR] 30 ml/min/1.73 m(2)) and 41 controls without renal disease undergoing scheduled coronary angiography. BP in the ascending aorta was measured through the angiography catheter and simultaneously estimated using radial tonometry. The mean difference between estimated central and aortic SBP was -13.2 (95% confidence interval -14.9 to -11.4) mm Hg. Arterial stiffness was evaluated by carotid-femoral pulse wave velocity (cf-PWV) and was significantly increased in CKD patients compared with (versus) control patients (mean 10.7 vs. 9.3 m/s). The difference in BP significantly increased 1.0 mm Hg for every 10 ml/min decrease in eGFR and by 1.6 mm Hg per 1 m/s increase in cfPWV. Using multivariate regression analysis including both eGFR and cfPWV, the difference between estimated central and invasive aortic SBP was significantly increased by 0.7 mm Hg. For the entire cohort brachial SBP significantly better reflected invasive SBP than estimated SBP. Thus, tonometry-based estimates of central BP progressively underestimate invasive central SBP with decreasing renal function and increasing arterial stiffness in CKD patients.

    Sacral Theater has been developed for the toroid magnet Atlas of the CERN LHC project. This three dimensional calculations code calculates the propagation of the transition of a superconducting coil in 25 m long hippodrome. Procedures to study low currents have been included. This work is a part of the magnet safety system because the coils protection is made by warmers activating the quench propagation in case of default detection. This allows the complete dissipation of storage energy that can reach 1080 MJ on Atlas. (N.C.)

    Background: Application noninvasive ventilation in the patients with exacerbation of chronic obstructive pulmonary disease (COPD) reduced mortality. This case-control study was designed to compare efficiency and outcome of non-invasive (NIV) versus invasive positive pressure ventilation (IPPV) in respiratory failure due to COPD. Methods: The patients were assigned to NIV or IPPV intermittantly.The clinical parameters, including RR (respiratory rate), BP (blood pressure), HR (heart rate) and PH, PaCO2, PaO2 before and 1, 4 and 24 h after treatment were measured. Demographic information such as age, sex, severity of disease based on APACHE score, length of stay and outcome were recorded. Results: Fifty patients were enrolled in the NIV group and 50 patients in IPPV. The mean age was 70.5 in NIV and 63.9 in invasive ventilation group (p>0.05). In IPPV group, the average values of PH: PCO2: and PO2, were 7.22±0.11, 69.64 + 24.25: and 68.86±24.41 .In NIV, the respective values were 7.30±0.07, 83.94±18.95, and 60.60±19.88. In NIV group, after 1, 4 and 24 h treatment, the clinical and ventilation parameters were stable. The mean APACHE score in was IPPV, 26.46±5.45 and in NIV was 12.26±5.54 (p<0.05). The average length of hospital stay in IPPV was 15.90±10 and in NIV 8.12±6.49 days (p<0.05). The total mortality in the NIV was 4 (8%) and in IPPV, 27 patients (54%) (p<0.05). Conclusion: This study indicates that using NIPPV is a useful therapeutic mode of treatment for respiratory failure with acceptable success rate and lower mortality. The application of NIPPV reduces hospital stay, intubation and its consequent complications. PMID:27386061

    To determine the MR features of non-sacral, non-clival chordoma and to describe a MR prototype of the lesion.Design and patients We reviewed the MR findings of 10 patients with a histologically proven chordoma (6 cervical spine, 1 thoracic spine, 3 lumbar spine). There were three female and seven male patients. Age ranged from 12 to 66 years with a mean age of 44.6 years. The MR images were reviewed for signal intensity (SI) and morphology. All lesions showed a soft tissue extension spanning several vertebral segments. Most of the lesions exhibited a so-called collar button appearance (sagittal images). Two cases of cervical chordoma displayed a ''dumbbell morphology'' (axial images) or ''mushroom'' appearance without bone involvement and with enlargement of the neuroforamen mimicking a neurogenic tumor. Although the region of the nucleus pulposus is the last part of the fetal notochord in the adult to involute, disks were surprisingly spared in all patients. Eight of 10 patients showed heterogeneous SI on all sequences. The overall SI of all lesions was isointense or slightly higher than that of muscle on T1-weighted images. All lesions exhibited high SI on T2-weighted images. After gadolinium contrast administration there was a moderate enhancement in most cases. Although the SI on MR imaging is not specific, chordoma should be considered when a destructive lesion of a vertebral body is associated with a soft tissue mass with a collar button or mushroom appearance and dumbbell morphology, spanning several vertebral segments and sparing the disk(s).

    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

Kuigi seda pühadusedefitsiiti on püütud leevendada ennekõike orientaalsetest teatrivormidest inspiratsiooni ammutades, aitab selle võimalikku tekkelugu mõista ka katoliikliku kultuuri mõjuväljas võrsunud teatrikunsti ning teatrivaenulikuma ortodoksi teoloogia kontekstis välja töötatud ikooniteoloogia võrdlus.

SU M M A R Y In the 21st century Western society has seen an increasing interest in topics related to religion. In this context, the connection between the concept of sacrality in Western culture and freedom of verbal and artistic expression has been reconsidered; the very possibility of so-called sacred art within Western culture has been called into question. Already in the 20th century several theatrical movements in the West have expressed the need to strive for religious (or at least quasi-religious goals by means of the stage. This can already be seen in the work of the symbolists, but such experiments accelerated and became more forceful under the influence of Antonin Artaud’s visions and under the aegis of intercultural theatre. In all of these different quests one can find common elements: discontent with the discursivity of the theatrical canon, a need for a metaphysical dimension in the theatre, and the belief that channels of perception can be opened through contact with exotic ritual cultures. In his book Sacred Theatre Ralph Yarrow has attempted to define the criteria of sacrality in the theatre, drawing upon William S. Haney

    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

    A complete spinal cord injury model was established in experimental rabbits using the spinal cord clip compression method. Urodynamic examination was performed 2 weeks later to determine neurogenic bladder status. The rabbits were treated with anodal block stimulation at sacral anterior roots for 4 weeks. Electrical stimulation of sacral anterior roots improved urodynamic parameters of neurogenic bladder in rabbit models of complete spinal cord injury, effectively promoted urinary function, and relieved urinary retention. Immunohistochemistry results showed that a balance was achieved among expression of muscarinic receptor subunits M2, M3, ATP-gated ion channel P2X3 receptors, and β2-adrenergic receptor, and nerve growth factor expression decreased. These results suggested that long-term sacral anterior root stimulation of anodal block could be used to treat neurogenic bladder in a rabbit model of complete spinal cord injury.

    Objective: To provide a new method in the fixation of sacral fracture by means of three-dimensional reconstruc-tion and reverse engineering technique.Methods: Pelvis image data were obtained from three-dimensional CT scan in patients with sacral fracture. The data were transferred into a computer workstation. The three-dimensional models of pelvis were reconstructed using Amira 3.1 software and saved in STL format. Then the three-dimensional fracture models were imported into Imageware 9.0 software. Different situations of reduction (total reduction, half reduction and non-reduction) were simulated using Imageware 9.0 software. The best direction and loca-tion of extract iliosacral lag screws were defined using re-verse engineering according to these three situations and navigation templates were designed according to the ana-tomic features of the postero-iliac part and the channel. The exact navigational template was made by rapid prototyping.Drill guides were sterilized and used intraoperatively to as-sist in surgical navigation and the placement of iliosacral lag screws.Results: Accurate screw placement was confirmed with postoperative X-ray and CT scanning. The navigation template was found to be highly accurate. Conclusion: The navigation template may be a useful method in minimal-invasive fixation of sacroiliac joint fracture.

    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.

    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

    Abstract Noninvasive positive-pressure ventilation (NPPV) might be superior to conventional mechanical ventilation (CMV) in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPDs). Inefficient clearance of respiratory secretions provokes NPPV failure in patients with hypercapnic encephalopathy (HE). This study compared CMV and NPPV combined with a noninvasive strategy for clearing secretions in HE and AECOPD patients. The present study is a prospective cohort study of AECOPD and HE patients enrolled between October 2013 and August 2015 in a critical care unit of a major university teaching hospital in China. A total of 74 patients received NPPV and 90 patients received CMV. Inclusion criteria included the following: physician-diagnosed AECOPD, spontaneous airway clearance of excessive secretions, arterial blood gas analysis requiring intensive care, moderate-to-severe dyspnea, and a Kelly–Matthay scale score of 3 to 5. Exclusion criteria included the following: preexisting psychiatric/neurological disorders unrelated to HE, upper gastrointestinal bleeding, upper airway obstruction, acute coronary syndromes, preadmission tracheostomy or endotracheal intubation, and urgent endotracheal intubation for cardiovascular, psychomotor agitation, or severe hemodynamic conditions. Intensive care unit participants were managed by NPPV. Participants received standard treatment consisting of controlled oxygen therapy during NPPV-free periods; antibiotics, intravenous doxofylline, corticosteroids (e.g., salbutamol and ambroxol), and subcutaneous low-molecular-weight heparin; and therapy for comorbidities if necessary. Nasogastric tubes were inserted only in participants who developed gastric distension. No pharmacological sedation was administered. The primary and secondary outcome measures included comparative complication rates, durations of ventilation and hospitalization, number of invasive devices/patient, and in-hospital and 1-year mortality

    Chronic sinusitis is a common disease that encompasses a number of syndromes that are characterized by sinonasal mucosal inflammation. Chronic sinusitis can be defined as two or more of the following symptoms lasting for more than 12 consecutive weeks: discolored rhinorrhea, postnasal drip, nasal obstruction, facial pressure or pain, or decreased sense of smell. Chronic sinusitis is further classified as chronic sinusitis with polyposis, chronic sinusitis without polyposis, or allergic fungal sinusitis using physical examination, and histologic and radiographic findings. Treatment methods for chronic sinusitis are based upon categorization of the disease and include oral and inhaled corticosteroids, nasal saline irrigations, and antibiotics in selected patients. Understanding the various forms of chronic sinusitis and managing and ruling out comorbidities are key to successful management of this common disorder.

    The responsiveness of hypothalamic CRF to various stressors is reduced in the young female Lewis relative to the histocompatible Fischer rat. Whether such a difference impacts the brain-gut response to water avoidance stress was investigated by monitoring Fos immunoreactivity in the brain and sacral spinal cord and fecal pellet output. Exposure for 60 min to water avoidance stress increased the number of Fos positive cells in the paraventricular nucleus of the hypothalamus (PVN), nucleus tractus solitarius (NTS), and the parasympathetic nucleus of the lumbo-sacral spinal cord (L6-S1) in both Lewis and Fischer rats compared with non stress groups. The Fos response was lower by 32.0% in the PVN, and 63% in sacral parasympathetic nucleus in Lewis compared with Fischer rats while similar Fos expression was observed in the NTS. Stress-induced defecation was reduced by 52% in Lewis compared with Fischer rats while colonic motor response to CRF injected intracisternally resulted in a similar pattern and magnitude of defecation in both strains. The CRF receptor antagonist [D-Phe12,Nle(21,38)C(a)MeLeu(37)]-CRF(12-41) injected intracisternally antagonized partly the defecation response in Lewis and Fischer rats. These data indicate that a lower activation of PVN and sacral parasympathetic nuclei in Lewis compared with Fisher rats may contribute to the differential colonic motor response and that the blunted CRF hypothalamic response to stress, unlike responsiveness to central CRF plays a role.

    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.)

    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.

    A retrospective, exploratory study was conducted as part of a performance improvement project examining pressure ulcer development in children. In 1 year, 69 children visited the hospital's wound clinic: 50 children had pressure ulcers, and 19 children had skin breakdown secondary to delayed operative wound healing. This article reviews findings from the 50 children with pressure ulcers. The primary diagnosis was myelodysplasia. Risk factors identified included (a) paralysis, (b) insensate areas, (c) high activity, and (d) immobility. The majority of the pressure ulcers occurred in the lower extremities, primarily the feet. As children get older or neurological condition deteriorates, sacral ulcers are seen particularly among wheelchair users. Pressure ulcers occur predominantly in the child's home environment.

    Chronic wounds including diabetic foot ulcers, pressure ulcers, and venous leg ulcers are a worldwide health problem. It has been speculated that bacteria colonizing chronic wounds exist as highly persistent biofilm communities. This research examined chronic and acute wounds for biofilms and characterized microorganisms inhabiting these wounds. Chronic wound specimens were obtained from 77 subjects and acute wound specimens were obtained from 16 subjects. Culture data were collected using standard clinical techniques. Light and scanning electron microscopy techniques were used to analyze 50 of the chronic wound specimens and the 16 acute wound specimens. Molecular analyses were performed on the remaining 27 chronic wound specimens using denaturing gradient gel electrophoresis and sequence analysis. Of the 50 chronic wound specimens evaluated by microscopy, 30 were characterized as containing biofilm (60%), whereas only one of the 16 acute wound specimens was characterized as containing biofilm (6%). This was a statistically significant difference (p<0.001). Molecular analyses of chronic wound specimens revealed diverse polymicrobial communities and the presence of bacteria, including strictly anaerobic bacteria, not revealed by culture. Bacterial biofilm prevalence in specimens from chronic wounds relative to acute wounds observed in this study provides evidence that biofilms may be abundant in chronic wounds.

    The purpose of the present investigations was (1) to examine the spatial organization of preganglionic neurons of the sacral parasympathetic nucleus in the lumbosacral spinal cord of male adult rats and (2) to search, in this nucleus, for a possible segregation of sub-populations of neurons innervating the penis or the bladder, respectively. To estimate their spatial organization, neurons of the sacral parasympathetic nucleus were retrogradely labeled by wheat germ agglutinin coupled to horseradish peroxidase applied to the central end of the sectioned pelvic nerve. The sub-populations of lumbosacral neurons innervating the corpus cavernosum of the penis or the dome of the bladder were identified using transsynaptic retrograde labeling by pseudorabies virus injected into these organs in different rats. In both wheat germ agglutinin-labeled and pseudorabies virus-labeled rats, serial coronal sections were cut through the spinal L5-S1 segments. Labeled neurons were revealed by histochemistry (peroxidase experiments) or immunohistochemistry (pseudorabies virus experiments). By means of a three-dimensional reconstruction software developed in our laboratory, three-dimensional models were calculated from each spinal section image series. They revealed the spatial organization of (i) preganglionic neurons and (ii) neurons innervating the bladder or the penis. The different three-dimensional models were subsequently merged into a single one which revealed the segregation, within the sacral parasympathetic nucleus, of the sub-populations of neurons. Neurons labeled by virus injected into the penis extended predominantly from the rostral part of the L6 segment to the rostral part of the S1 segment while those labeled by bladder injections were distributed predominantly from the caudal part of the L6 segment to the caudal part of the S1 segment. These results support the hypothesis of a viscerotopic organization of sacral neurons providing the spinal control of pelvic organs.

    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.

    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.

    Full Text Available Background. We need to understand more about how DNF performs in different contexts and whether it affects the pain threshold over myofascial trigger points (MTrPs. Purpose. The objectives were to investigate the effect of neck muscles training on disability and pain and on pain threshold over MTrPs in people with chronic neck pain. Methods. Patients with chronic neck pain were eligible for participation with a Neck Disability Index (NDI score of over 5/50 and having at least one MTrP on either levator scapulae, upper trapezoid, or splenius capitis muscle. Patients were randomly assigned into either DNF training, superficial neck muscle exercise, or advice group. Generalized linear model (GLM was used to detect differences in treatment groups over time. Results. Out of 67 participants, 60 (47 females, mean age: 39.45 ± 12.67 completed the study. Neck disability and neck pain were improved over time between and within groups (p<0.05. However, no differences were found within and between the therapeutic groups (p<0.05 in the tested muscles’ PPTs and in cervicothoracic angle over a 7-week period. Conclusion. All three groups improved over time. This infers that the pain pathways involved in the neck pain relief are not those involved in pain threshold.

    Sacroiliac (SI) screw fixation for unstable pelvic fractures stands out as the only minimally invasive method among all other ORIF procedures. A strictly transverse screw trajectory is needed for central or bilateral fracture patterns up to a complete iliosacroiliac fixation. However, secure screw insertion is aggravated by a narrow sacroiliac bone stock. This study investigates the influence of a highly variable sacral morphology to the existence of S1 and S2 transverse corridors. The analysis contained in this study is based on 125 CT datasets of intact human pelvises. First, sacral dysplasia was identified using the "lateral sacral triangle" method in a lateral 3-D semi-transparent pelvic view. Second, 3-D corridors for a 7.3mm screw in the upper two sacral levels were visualised using a proprietary IT workflow of custom-made programme scripts based on the Amira(®)-software. Shape-describing measurement variables were calculated as output variables. The results show a significant linear correlation between ratioT and the screw-limiting S1 isthmus height (Pearson coefficient of 0.84). A boundary ratio of 1.5 represented a positive predictive value of 96% for the existence of a transverse S1-corridor for at least one 7.3mm screw. In 100 out of 125 pelvises (80%), a sufficient S1 corridor existed, whereas in 124 specimens (99%), an S2 corridor was found. Statistics revealed significantly larger S1 and S2 corridors in males compared to females (pS1 and 1 screw in S2. The expanse of the S1 corridor is highly influenced by the dimensions of the dysplastic elevated upper sacrum, whereas the S2 corridor is not affected. Hence, in dysplastic pelvises, sacroiliac screw insertion should be recommended into the 2nd sacral segment. Our IT workflow for the automatic computation of 3-D corridors may assist in surgical pre-operative planning. Furthermore, the workflow could be implemented in computer-assisted surgery applications involving pelvic trauma.

    The effects of an ACE-inhibitor (ramipril), a calcium antagonist (felodipine) and placebo on glomerular filtration rate (GFR), urinary albumin/creatinine ratio, blood pressure (BP) and vasoactive hormones were investigated in a randomized, prospective, double-blind, placebo-controlled study of patients with chronic glomerulonephritis and hypertension, with measurements at entrance and after 12 and 24 months. In total, 33 patients were included: 21 completed the study with 7 patients in each group. GFR was measured as 51Cr-EDTA clearance and the vasoactive hormones with radioimmunoassays. The reduction in GFR was significantly more pronounced in the felodipine group (-7 ml/min) than in the ramipril group (0 ml/min) but the same as in the placebo group (-6 ml/min). The urinary albumin/creatinine ratio was significantly more reduced in the ramipril group (-74 mg/mmol) than in the placebo group (-11 mg/mmol), which did not deviate from the felodipine group (-10 mg/mmol). BP was significantly reduced by ramipril and felodipine, but not by placebo. Angiotensin II and aldosterone in plasma increased or tended to increase in the felodipine and placebo groups, but were unchanged in the ramipril group. Endothelin increased only in the placebo group, and vasopressin, atrial natriuretic peptide, and brain natriuretic peptide were not significantly changed in any of the groups. It is concluded that ramipril seems to be superior to felodipine in chronic glomerulonephritis owing to better preservation of GFR.

    Antihypertensive treatment is an essential, life-prolonging measure in primary hypertension. It prevents apoplexy, myocardial infarction, and hypertensive kidney failure. Chronic kidney failure is associated with hypertension and an accelerated form of arteriosclerosis. Demise from cardiovascular affliction is a leading cause of death in renal patients (chronic renal failure stages II-IV, renal failure requiring dialysis, renal transplantation). What, then, is the role of antihypertensive treatment in such patients, and, specifically, what is achieved by renin-angiotensin-aldosterone (RAA) system modifying agents? Two meta-analyses have recently investigated these issues. An article in The Lancet evaluated eight studies on dialysis patients (n = 1679). It concluded that antihypertensives are beneficial in reducing cardiovascular morbidity and mortality. However, we criticize these conclusions and show that the data are not convincingly in favor of antihypertensive treatment. A meta-analysis in the American Heart Journal assessed the role of antihypertensive agents and RAA system modifying drugs in 45,758 patients (from 25 studies), who were in stages I-III of renal failure, i.e., not (yet) requiring dialysis. The authors claim that angiotensin- -converting enzyme inhibitors/angiotensin receptor blockers (ACEI/ARB) significantly reduced cardiovascular outcomes. However, our analysis of the data is not consistent with their conclusions. It showed that the results were quite mixed, that the authors may have overemphasized the positive results, and that considering all the results, it should be concluded that antihypertensive treatments, including those with ACEI/ARB, may not be superior to placebo (sic!) in renal patients. Rather than doing meta-analyses, larger primary studies are needed to reveal the real role of antihypertensive treatments in renal patients.

    This prospective study compares different clinical characteristics and outcomes of patients with two types of sacral extradural spinal meningeal cysts (SESMC) undergoing different means of surgical excision. Using the relationship between the cysts and spinal nerve roots fibers (SNRF) as seen under microscope, SESMCs were divided into two types: cysts with SNRF known as Tarlov cysts and cysts without. The surgical methods were tailored to the different types of SESMCs. The improved Japanese Orthopedic Association (IJOA) scoring system was used to evaluate preoperative and postoperative neurological function of the patients. Preoperative IJOA scores were 18.5 ± 1.73, and postoperative IJOA scores were 19.6 ± 0.78. The difference between preoperative and postoperative IJOA scores was statistically significant (t = -4.52, p = 0.0001), with a significant improvement in neurological function after surgery. Among the improvements in neurological functions, the most significant was sensation (z=-2.74, p=0.006), followed by bowel/bladder function (z=-2.50, p=0.01). There was a statistically significant association between the types of SESMC and the number (F=12.57, p=0.001) and maximum diameter (F=8.08, p=0.006) of the cysts. SESMC with SNRF are often multiple and small, while cysts without SNRF tend to be solitary and large. We advocate early surgical intervention for symptomatic SESMCs in view of significant clinical improvement postoperatively.

    Untreated or sub-clinical hypothyroidism is associated with insulin resistance, obesity, adverse effects on cardiovascular system, hypertension and in turn risk of nephropathy. However, these changes are reversible with thyroxine replacement therapy (TRT). Current research studied 4235 diabetic patients, divided into two groups, those with clinical hypothyroidism /on TRT, compared to those without thyroid disease or undiagnosed. BMI, blood pressure, creatinine, urine microalbumin and spot urine protein levels were compared between these two groups. Study finding demonstrated that for hypothyroid cases, BMI was higher (32.2 ± 7.44 versus 29.4 ± 5.7; p hypothyroidism (on TRT) was strongly associated with obesity (p hypothyroidism.

    Objective To evaluate the efficiency of normal sacral nerve root transposition in repair of the sacral plexus root avulsion. Methods A total of 30 adult SD rats were chosen and divided into three groups,ie,group A(the sciatic nerve received no repair),group B(the autologous sacral plexus root nerve was bridged with the right L6 nerve root by the translocation of the left L6)and group C (the right L5 nerve root nerve was bridged by the translocation of the left L6),10 rats per group.The left side of the rats was used as the control side and the right one as the experimental side.Twelve weeks after operation,the rats in each group were selected for the histomorphological observation of the nerves under the microscope and the electron microscope.The models were evaluated by observing the survival rates of the rats,BBB scores,electron microscope weight and muscle fiber CSA(cross section area)of double biceps femoris,triceps surae and tibial muscle. Results Twelve weeks after operation,the BBB scores in groups B and C was higher than that in group A,with statistical difference(P<0.01)between three groups.A remarkable improvement was found in the ratio of weight and muscle fiber CSA of double biceps femoris,triceps surse and tibial muscle.The repair efficiency in the group C was better than that in the group B.In the group B,the biceps femoris,triceps surae and tibial muscle recovered at different degrees.The biceps femoris recovered the best,when a great deal of myelinated nerve fiber regeneration was observed under the microscope and the electromicroscope.Electromyography revealed the volatility in the muscles of three groups,with larger peak value for the proximal biceps femoris and the triceps muscle but smaller peak value for the distal anterior tibial muscle. Conclusions L6 transposition combined with auto-graft of nerve root or without the auto-graft can reconstruct the partial function of the sciatic nerve in the paraplegia rats,when the latter has the better

    Objective:Free-hand pedicle screw placement has a high incidence of pedicle perforation which can be reduced with fluoroscopy,navigation or an alternative rapid prototyping drill guide template.In our study the error rate of multi-level templates for pedicle screw placement in lumbar and sacral regions was evaluated.Methods:A case series study was performed on 11 patients.Seventy-two screws were implanted using multilevel drill guide templates manufactured with selective laser sintering.According to the optimal screw direction preoperatively defined,an analysis of screw misplacement was performed.Displacement,deviation and screw length difference were measured.The learning curve was also estimated.Results:Twelve screws (17%) were placed more than 3.125 mm out of its optimal position in the centre of pedicle.The tip of the 16 screws (22%) was misplaced more than 6.25 mm out of the predicted optimal position.According to our predefined goal,19 screws (26%) were implanted inaccurately.In 10 cases the screw length was selected incorrectly:1 (1%) screw was too long and 9 (13%) were too short.No clinical signs of neurovascular lesion were observed.Learning curve was insignificantly noticeable (P=0.129).Conclusion:In our study,the procedure of manufacturing and applying multi-level drill guide templates has a 26% chance of screw misplacement.However,that rate does not coincide with pedicle perforation incidence and neurovascular injury.These facts along with a comparison to compatible studies make it possible to summarize that multi-level templates are satisfactorily accurate and allow precise screw placement with a clinically irrelevant mistake factor.Therefore templates could potentially represent a useful tool for routine pedicle screw placement.

    Objective To investigate the selective innervation of sacral anterior rootlets to micturition and erection function in SD rats. Methods Forty male SD rats of clean grade, aged 6 weeks old, were selected. Ten rats received a retrograde nerve tract tracing study. Thirty rats were chosen for an electro-physiological study. The L6, S1 spinal cord segment anterior rootlets of anesthetic rats were electrostimulated respectively. The intravesical pressure, urethral perfusion pressure and intracarvernerous pressure were recorded simultaneously and innervation effectiveness was analyzed. Results CB-HRP labeled neurons were observed mainly in L6 and S1 spinal cords. When some anterior rootlets of L6 and S1were electrostimulated, the intravesical pressure rose gradually, but the urethral perfusion pressure and the intracavernous pressure curve changed slightly; when other rootlets of the same anterior root were stimulated,the urethral perfusion pressure could reach the peak; while others were stimulated, the intracavernours pressure rose quickly, but there were no great changes in intravesical pressure and urethral perfusion pressure. Some other rootlets might lead to the simultaneous changes of 2 or 3 above-mentioned pressures.Conclusion The innervations of L6 and S1 anterior rootlets to rats' bladder detrusor, external urethral sphincter and penile cavernous body are significantly distinct. Different rootlets may be distinguished by microanatomy and electrostimulation.%目的 探讨脊神经前根小束对SD大鼠膀胱和勃起功能的选择性支配机制.方法 成年雄性SD大鼠40只,10只行逆行神经示踪,30只行电生理研究:分别刺激大鼠排尿及勃起反射中枢所在脊髓节段的脊神经前根神经小束,同时记录膀胱内压、尿道灌注压和阴茎海绵体内压的变化.结果 SD大鼠排尿和勃起功能的低级中枢主要位于L6、S1脊髓节段,电刺激L6、S1脊神经前根某些小束分别引起膀胱内压、尿道灌注压

    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.

    Microcirculation is essential for proper supply of oxygen and nutritive substances to the biological tissue and the removal of waste products of metabolism. The determination of microcirculatory blood flow (mBF) is therefore of substantial interest to clinicians for assessing tissue health; particularly in pressure ulceration and suspected deep tissue injury. The goal of this pilot clinical study was to assess deep-tissue pressure ulceration by non-invasively measuring mBF using Diffuse Correlation Spectroscopy (DCS). DCS provides information about the flow of red blood cells in the capillary network by measuring the temporal autocorrelation function of scattering light intensity. A novel optical probe was developed in order to obtain measurements under the load of the subject's body as pressure is applied (ischemia) and then released (reperfusion) on sacrococcygeal tissue in a hospital bed. Prior to loading measurements, baseline readings of the sacral region were obtained by measuring the subjects in a side-lying position. DCS measurements from the sacral region of twenty healthy volunteers have been compared to those of two patients who initially had similar non-blanchable redness. The temporal autocorrelation function of scattering light intensity of the patient whose redness later disappeared was similar to that of the average healthy subject. The second patient, whose redness developed into an advanced pressure ulcer two weeks later, had a substantial decrease in blood flow while under the loading position compared to healthy subjects. Preliminary results suggest the developed system may potentially predict whether non-blanchable redness will manifest itself as advanced ulceration or dissipate over time.

    was conducted to review 72 patients who underwent superior sacral tumor resection and had complete medical records from January 1998 to August 2011. The inclusive criteria were that the patients with dural injuries during sacrum tumor resection had CSF leakage postoperatively, meanwhile excluding those who had contraindications after continuous lumbar puncture CSF drainage such as brain hernia, intracranial pressure increased obviously, skin or soft tissue infection in puncture position, systemic inflammatory response syndrome ( SIRS ) to severe sepsis or septic shock, not cooperating puncture, CSF circulation channel obstruction above L3 etc. 11 patients were in accordance with the inclusive criteria ifnally. 5 patients with CSF leakage after sacrum tumor resection who underwent single drainage using a tube beside the wound before March 2005 were taken as the control group. While the other 6 patients who had CSF leakage after sacrum tumor resection after March 2005 were taken as the continuous lumbar puncture drainage group. The healing time of CSF leakage, the general condition of patients and related complications were compared between the 2 groups. Results No retrograde intracranial infection occurred in both groups, while 1 patient in the control group had local infection of operative incision. The healing time of the patients in the continuous lumbar puncture drainage group was at a median of 14.5 days ( range;12-18 days ), while 25 days ( range;23-36 days ) in the control group, and there were statistically signiifcant differences between them ( P=0.004 ). Less oozing or swelling appeared in the operative incision of the sacrococcygeal region of the continuous lumbar puncture drainage group during the treatment than that of the control group. At the same time, self-feelings of patients in the continuous lumbar puncture drainage group, such as wound pain, dizziness symptoms and so on, were lighter than that of the control group. No patients in both groups had

Results. The analysis of effects of various medical methods on a condition of local blood circulation in the bottom extremities showed that the most expressed its compensation is noted at complex application of mechanical pulse traction influence and electrotherapy for patients with a dorsopathy of lumbar and sacral department of a backbone that is confirmed by restoration to normal values of all indicators rheovasogramm. Conclusion. High clinical results of application of the combined medical and rehabilitation complex are based on compensation of local blood circulation that is shown in elimination of deficiency of blood supply due to improvement of a tone of arterial vessels and elimination of venous stagnation, and also due to increase of linear speed of a blood-groove and development of collateral blood circulation. Application of electrical impulse and mechanical traction influences, more at their combination promotes fermentative activity of the systems responsible for a protein exchange that is important for prevention of degenerate and dystrophic process progressing.

    Spina bifida is a complex congenital malformation resulting from failure of fusion in the spinal neural tube during embryogenesis. However, the cellular mechanism underlying spina bifida is not fully understood. Here, we investigated cell apoptosis in whole embryos and proliferation of neural progenitor cells in the spinal neural tube during neurulation in all-trans retinoic acid (atRA)-induced spina bifida in fetal rats. Cell apoptosis was assessed by TUNEL assay on whole-mount and serially sectioned samples of rat embryos with spina bifida. Cell proliferation of lumbo-sacral neural progenitor cells was assessed by staining for the mitotic marker Ki67 and pH3. We found an excess of apoptosis in the neuroepithelium of embryos with spina bifida, which became more marked as embryos progress from E11 to E13. Conversely, there was a reduction in cell proliferation in spina bifida embryos, with a progressively greater difference from controls with stage from E11 to 13. Thus, atRA-induced spina bifida in rat shows perturbed apoptosis and proliferation of neural progenitors in the lumbo-sacral spinal cord during embryonic development, which might contribute to the pathogenesis of spina bifida.

    U-shaped sacral fractures usually occur in multiply injured patients after falling from height. However, it is often missed or delayed in diagnosis because of other severe associated injuries. Due to its low incidence, the experience of the diagnosis and treatment of U-shaped sacral fractures is very limited. In this article, the treatment outcomes of lumbopelvic fixation for unstable U-shaped sacral fractures were retrospectively studied. From 2008 to the present, 4 patients with U-shaped sacral fractures were treated by lumbopelvic fixation, among whom there were 3 males and 1 female, with an average age of 30 years old (range;20-45 years). According to the Roy-Camille system, there were 2 cases of Type 2 and 2 cases of Type 3. All patients underwent the bone chip removal, sacral canal decompression and lumbopelvic pedicle screw fixation. 3 patients with cauda equina injuries underwent cauda equina release after decompression. All patients were followed up with a mean period of 2 years and 6 months (range;2-4 years). In 2 patients, the bladder and bowel function was restored about 3 months postoperatively, with gradually normal ambulation 6 months postoperatively. Only paresthesia or numbness remained in some areas in lower limbs 2 years postoperatively. In 1 patient, the bladder and bowel function was restored 1 month postoperatively, with gradually normal ambulation and improved muscle weakness 3 months postoperatively. He entirely got recovered 2 years postoperatively. 1 patient with U-shaped sacrum fractures, combined with no neurological damage could gradually move around 1 month postoperatively, and the sensory-motor of lower limbs was completely normal during the 4-year follow-up. In summary, for patients with U-shaped sacral fractures, combined with obvious fracture displacement and neurological damage, lumbopelvic pedicle screw fixation can significantly correct the displaced and deformed fractures during the surgery and is in favor of adequate nerve

    Pulse pressure (PP) remains an elusive cardiovascular risk factor with inconsistent findings. We clarified the prognostic value in patients with type 2 diabetes, chronic kidney disease (CKD) and anemia in the Trial to Reduce cardiovascular Events with Aranesp (darbepoetin alfa) Therapy. In 4038 type 2 diabetes patients, darbepoetin alfa treatment did not affect the primary outcome. Risk related to PP at randomization was evaluated in a multivariable model including age, gender, kidney function, cardiovascular disease (CVD) and other conventional risk factors. End points were myocardial infarction (MI), stroke, end stage renal disease (ESRD) and the composite of cardiovascular death, MI or hospitalization for myocardial ischemia, heart failure or stroke (CVD composite). Median (interquartile range) age, gender, eGFR and PP was 68 (60-75) years, 57.3% women, 33 (27-42) ml min(-1) per 1.73 m2 and 60 (50-74) mm Hg. During 29.1 months (median) follow-up, the number of events for composite CVD, MI, stroke and ESRD was 1010, 253, 154 and 668. In unadjusted analyses, higher quartiles of PP were associated with higher rates per 100 years of follow-up of all end points (P⩽0.04), except stroke (P=0.52). Adjusted hazard ratios (95% confidence interval) per one quartile increase in PP were 1.06 (0.99-1.26) for MI, 0.96 (0.83-1.11) for stroke, 1.01 (0.94-1.09) for ESRD and 1.01 (0.96-1.07) for CVD composite. Results were similar in continuous analyses of PP (per 10 mm Hg). In patients with type 2 diabetes, CKD and anemia, PP did not independently predict cardiovascular events or ESRD. This may reflect confounding by aggressive antihypertensive treatment, or PP may be too rough a risk marker in these high-risk patients.

    According to the nature of the sacral tumor, it could lead to the extrusion, invasion and destruction of the sacral nerve. S4 and S5 nerve were usually cut off, when S4 and S5 were fouled by sacral tumors. The tumor tissues of the benign sacral tumor in S3 and above were always scraped within the lesion, so that we should protect the nerve root to save the motion of lower limbs and urination function. The author's experience: after keeping the nerve root of S1 and above, all the patients would be of the loss of urination function, and need to be catheterized in time. After keeping the nerve root of S3 and above, all patients could urinate. After keeping the nerve root of S2 and above, some of patients could urinate while others couldn't.

    1984-05-01

    Chronicity in psychopathology is indicative of a term, a decay. Chronicization only leads the way to this term. Here, chronicization is taken literally as an inscription in the time course of delusions. The mechanism of systematization seems to be a central mark in the approach to chronic delusions. It is not an alienation or an irreversible closing but an attempted accommodation with reality in the life of psychotic subjects, irrespective of the delusional structure. The role of therapy and drug treatment as a follow-up may in that case assume another meaning.

Pressure ulcers have significant impact on emotional and physical wellbeing, quality of life, and health care costs. The use of wound dressings could be an important and cost-effective strategy in preventing pressure ulcers. The main types of dressings that are examined for this purpose in the literature are foam, hydrocolloid, and films. Some small studies have shown a preventative role for sacral dressings with low-shear backings, though they raise concerns about over-hydration of the skin. Further research demonstrates the application of barrier films over bony prominences to have a prophylactic effect; however, adhesive dressings can also contribute to shearing forces on the skin. There is a vast body of research that examines the use of dressings to prevent pressure ulcers; however, there is limited high-level evidence, such as randomized control trials. A 2013 Cochrane review indicated that there is a paucity of high-level evidence to support the prophylactic use of dressings to prevent pressure ulcers; this paper will examine the emerging literature and consider its relevance to pressure ulcer prevention protocols. Keywords: quality of life, hydrocolloid dressing, topical agent

    2003-12-01

    Integrated neuromusculoskeletal release (INR) using a segmental anterior/posterior approach is an osteopathic manipulative treatment technique that is easily learned and applied. The segmental anterior/posterior approach to INR was developed as a practical osteopathic manipulative treatment procedure for the inpatient setting, but also has equal efficacy in the outpatient setting. It builds on the principles of INR and myofascial release techniques, as well as other techniques. This approach focuses on both the anterior and posterior connectivity of the body through the neuromusculoskeletal system and uses this connectivity to effectively treat somatic dysfunctions. The principles of INR are discussed, as well as the role of INR in the diagnosis and treatment of somatic dysfunctions in the thoracic, lumbar, and sacral regions.

    Multiple neural tube defects are relatively rare. They account for less than 1% reported neural tube defects. Cases of limited dorsal myeloschisis (LDM) and diplomyelia (two cords in single sac without intervening bony or fibrous septae) with dorsal bony spur are also a rare event. Here, the authors report a rare case of neonate with thoracic LDM, diplomyelia with dorsal bony spur, sacral meningocoele with syringohydromyelia, and low-lying tethered cord. The child also had a ventricular septal defect (VSD) and bilateral rocker bottom feet. Various environmental factors and genetic mutations in transmembrane proteins have been studied in animal models explaining the origin of neural tube defects. To the best of author's knowledge, this is the first case of varied multiple neural tube defects with diplomyelia reported in world literature.

  12. 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.

    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.

    Full Text Available Objective: Pressure ulcer is a chronic wound. It reduces the quality of life of the elderly and individuals with restricted range of motion. It prolongs hospital stay and increases the risk of complications. The cost is quite high. Preventive actions for the prevention of pressure ulcers should be developed. Planning protocols and standards of care are among the main targets. Material and Method: Research was conducted in one-year period between 2012 May and 2013 May on patients who were followed up in Akdeniz University Hospital clinics and intensive care unit with pressure ulcers. The research population consisted of 569 patients. Patient data were recorded in SPSS 16 for Windows program. Statistical analyzes were performed with retrospective methods. The demographic characteristics of patients with pressure ulcers were analyzed as frequency and descriptive statistics. Prevalence and incidence of one year were calculated. Results: Of the patients, 58% were males, 42% were females. Of the patients, 36% were in the age range of 61-80 years, and their average length of stay was 42,9 days. Of the patients, 70% were at stage 2 and 3. In 15% of patients pressure ulcers occurred on the first day of hospitalization. Pressure ulcers were developed between days 2 and 10 in 59% of the patients. Prevalence rate was 2.5%, the incidence was 1.9%, the prevalence rate was 5.9% in the intensive care unit. Conclusion: It is easier to prevent pressure ulcers than treating.

    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.

    BACKGROUND: There have been many methods of fixation between lumbar-sacral spine and pelvis. However, a safe, firm, and ideal method of internal fixation has not been found.OBJECTIVE: This study was designed to investigate the stability of the fixation between lumbar-sacral spine and pelvis with the connectible skills using iliac screw and lumbar-sacral spine pedicle screw.DESIGN, TIME AND SETTING: This study, a control experiment, was performed at the Institute of Biomechanics, Sun Yat-sen University, Guangzhou, Guangdong Province, China between January 2006 and December 2007.MATERIALS: The lumbar-sacral spine and pelvis specimens were collected from six freshly cryo-preserved male adult corpses caused by trauma. Iliac screw (8.5mm×100mm), L5 pedicle screw (6.5mm×45mm), and S1 pedicle screw (6.5mm×35mm) were provided by Sofamor Company, USA. MTS 858 Bionix Material Testing System (USA) was also used.METHODS: The lumbar and iliac vertebrae, pelvis from six fresh frozen cadaveric specimens were operated in three different ways of fixation respectively: iliac ala lag screw, L5-S1 pedicle screw rod system, iliac screw and L5 pedicle screw connecting system. Three ways of fixation as mentioned above were compared with the intact group in biomechanical stability.MAIN OUTCOME MEASURES: The mobility of whirl, lateral bending, proneness, and backward stretching among groups.RESULTS: Using iliac screw for the fixation between lumbar-sacral spine and pelvis turned out to be the best in stability. The range of motion (ROM) decreased obviously in each situation. The three-dimensional mobility in the 6.4Nm moment of force was (1.07±0.86)° for whirl, (0.95±0.47)° for lateral bending, (1.22±0.67)° for proneness, and (1.80±0.73)° for backward stretching. There was significant difference between the intact group and the group carried out by iliac screw and L5 pedicle screw for the fixation between lumbar-sacral spine and pelvis (P<0.01).CONCLUSION: The connectible skills

    Medical literature about chronic hepatitis is reviewed. This unresolving disease caused by viruses, drugs or unknown factors may progress to in cirrhosis and hepatocarcinoma. A classification based on liver biopsy histology into chronic persistent and chronic active types has been largely abandoned and emphasis is placed on recognizing the etiology of the various types. One is associated with continuing hepatitis B virus infection; another is related to chronic hepatitis C virus infection and the third is termed autoinmune, because of the association with positive serum autoantibodies. A fourth type with similar clinical functional and morphologic features is found with some drug reactions. Long term corticoesteroid therapy is usually successful in autoinmune type. Associations between antibodies to liver-kidney microsomes and the hepatitis C virus can cause diagnostic difficulties. Antiviral treatment of chronic hepatitis B and C with interpheron alfa is employed, controlling symptoms and abnormal biochemistry and the progression to cirrhosis and liver cancer in 30 to 40% patients. Alternative therapies or combinations with interpheron are being evaluated waiting for final results.

    Full Text Available Chronic obstructive pulmonary disease, namely, pulmonary emphysema and chronic bronchitis, is a chronic inflammatory response of the airways to noxious particles or gases, with resulting pathological and pathophysiological changes in the lung. The main pathophysiological aspects of the disease are airflow obstruction and hyperinflation. The mechanical properties of the respiratory system and its component parts are studied by determining the corresponding volume-pressure (P-V relationships. The consequences of the inflammatory response on the lung structure and function are depicted on the volume-pressure relationships.

    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.

    Prevalence of chronic gastritis has markedly declined in developed populations during the past decades. However, chronic gastritis is still one of the most common serious pandemic infections with such severe killing sequelae as peptic ulcer or gastric cancer. Globally, on average, even more than half of people may have a chronic gastritis at present. Helicobacter pylori infection in childhood is the main cause of chronic gastritis, which microbial origin is the key for the understanding of the bizarre epidemiology and course of the disease. A life-long and aggressive inflammation in gastritis results in destruction (atrophic gastritis) of stomach mucosa with time (years and decades). The progressive worsening of atrophic gastritis results subsequently in dysfunctions of stomach mucosa. Atrophic gastritis will finally end up in a permanently acid-free stomach in the most extreme cases. Severe atrophic gastritis and acid-free stomach are the highest independent risk conditions for gastric cancer known so far. In addition to the risks of malignancy and peptic ulcer, acid-free stomach and severe forms of atrophic gastritis may associate with failures in absorption of essential vitamins, like vitamin B12, micronutrients (like iron, calcium, magnesium and zinc), diet and medicines.

    An 11-year-old boy was diagnosed with chronic recurrent multifocal osteomyelitis (CRMO) and presented with right sacro-femoral and occipital lesions. Initially, a tumor was suspected. However, the bone biopsy showed osteomyelitis with a negative bacterial culture. Bone scintigraphy revealed inflammatory changes on multiple bone lesions. The slight elevation in inflammatory markers such as C-reactive protein was of little clinical value. He was diagnosed with CRMO by sacral biopsy, and the clinical course progressed, with the presence of a new occipital lesion observed after the 1-year follow-up. The administration of non-steroidal anti-inflammatory drugs successfully improved his clinical symptoms. The presence of a skull lesion in the occipital bone of a pediatric patient with CRMO has not been previously reported.

    We report a case in which a radiation abscess with its drainage fistula of the presacral region was successfully treated. Eighteen years earlier, the patient, a 76-year-old female, had received radiation therapy after the excision of a uterine cancer. After this surgery, 11 years later, a presacral radiation abscess developed and was treated conservatively for 5 years. As the abscess did not respond, an incision was made for abscess drainage and this method was used for 2 years without success. Construction of a 3D solid model of her pelvis and fistulous tract led to the selection of an effective surgical approach that entailed a partial sacral resection (half of the S3 and the entire S4 and S5 regions), which allowed wide access to the presacral area, so that resecting the abscess was quite easy. On resection, the space was filled with a free latissimus dorsi musculocutaneous flap. The postoperative course has shown no morbidity and continues to remain uneventful. (author)

    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:The typical manifestation of neurogenic bladder is the dysfunction of bladder storage. This situation relates to the disorder of the sacral nerve directly or indirectly.To implant electrical sacral nerve root stimulator is believed to be a good method to improve the storage and voiding, by modulating the sacral spine. OBJECTIVE:To detect the effect of sacral nerve root stimulation on the neurogenic bladder. DESIGN:A total randomized and controlled study. SETTING and MATERIALS:Twenty female wistar rats,weighing 180-220 g,were provided by Center for Experimental Animals,Third Military Medical University.Models of neurogenic bladder were made, and divided randomly into the stimulation group(n=10) and the control group(n=10). INTERVENTION:Sacral nerve root stimulation is performed on the stimulation group, but not on the control group. MAIN OUTCOME MEASURE:After a month's stimulating, the urodynamics and the Caspase3 mRNA were detected. RESULTS:The storage volume of bladder increased significantly, with the bladder capacity increased by (0.095± 0.083) mL, and the bladder compliance increased(t=-3.92,P< 0.05).The expression of caspase3 mRNA decreased significantly by 0.58± 0.44 against the control group.

    Full Text Available Among the sociolinguistc forces at work in the languages of the world, religious affiliation and the accompanying reverence for the symbols of that affiliation must rank among the most powerful. Religious texts serve as repositories of cultural tradition and become, for their followers, reliquaries of the very word of God. Besides the conservatizing, archaizing pressures which often grow up within a religious tradition, these texts also act as conduits for cultural and linguistic innovation as they spread, through transmission and translation, to surrounding populations. The New Testament (NT represents just such a cultural conduit, providing not only a blueprint for Christian social behavior but also a pattern for Christian linguistic expression, providing a new lexicon, a special syntax, a style of its own, simple and spare. It was this style, these lexical and syntactic patterns, which came to be imbued with social value to connote membership in the Christian community, and which came to be imitated, sometimes subtly, sometimes blatantly, by translators of the New Testament.

    Objective To explore the operative techniques and effectiveness of triangular osteosynthesis for the treatment of Tile C1-3 pelvic ring injuries following sacral fracture. Methods From January 2009 to December 2010,22 patients with Tile C1-3 pelvic ring injuries following sacral fracture were treated with triangular osteosynthesis using a combination of Universal Spinal System (USS) and iliosacral screws in our hospital.Tbey were 13 males and 9 females,aged 21 to 48 years (average,31.2 years).By Tile classification,there were 9 cases of type C1,7 cases of type C2 and 6 cases of type C3.The average time from injury to definitive operation was 11.2 days (range,from 5 to 21 days).The reduction quality was evaluated according to the Matta criteria,functional outcome according to the Majeed criteria and nerve functional outcome according to the Gibbons criteria. Results The average blood loss was 450 mL(range,from 100 to 800 mL).The average hospital stay was 16 days (range,from 12 to 26 days).All patients were followed up for an average of 14 months (range,from 4 to 26 months).Local infection was seen in 2 patients and healed with aggressive debridement and antibiotics.Reduction loss or hardware failure was not seen in this series.All fractures were healed at the final radiological follow-up.Implant removal was performed in 15 patients.Reduction was excellent in 18 sides,good in 6 sides and fair in one side.The functional outcome at the last follow-up was excellent in 13 cases,good in 6 cases,fair in 2 cases and poor in one case.Of the 13 patients with preoperative neurologic impairment,6 achieved grade Ⅰ,4 grade Ⅱ,2 grade Ⅲ and one grade Ⅳ at the last follow-up. Conclusion As a relatively new fixation strategy for Tile C1-3 pelvic ring injuries following sacral fracture,triangular osteosynthesis using a combinatiou of USS and iliosacral screws can provide rigid fixation and permit early full weight-bearing post-operation because nerve decompression can be

    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.

    Objective To investigate the effects of inspiratory muscle training followed by non-invasive positive pressure ventilation in patients with severe chronic obstructive pulmonary disease (COPD). Methods This investigator-initiated randomized, controlled trial recruited 88 patients with stable GOLD stage IV COPD, who were randomized into 4 equal groups to continue oxygen therapy (control group) or to receive inspiratory muscle training followed by non-invasive positive pressure ventilation (IMT-NPPV group), inspiratory muscle training only (IMT group), or noninvasive positive pressure ventilation only (NPPV group) for at least 8 weeks. The outcomes of the patients were assessed including the quality of life (SRI scores), maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), dyspnea (MRC scores), 6-min walking distance (6MWD) and lung function. Results Compared to baseline values, SRI scores, 6MWT and MRC scores increased significantly after 8 weeks in IMT-NPPV, IMT and NPPV groups, and the improvements were significantly greater in IMT-NPPV group than in IMT and NPPV groups (P0.05). Conclusion Inspiratory muscle training followed by non-invasive positive pressure ventilation, compared with inspiratory muscle training or non-invasive positive pressure ventilation alone, can better enhance the quality of life, strengthen the respiratory muscles, improve exercise tolerance and relieve the dyspnea in patients with COPD.%目的:探讨呼吸肌肉锻练序贯无创通气的肺康复策略的临床应用价值。方法88例患者随机分为序贯组、呼吸肌肉锻炼组、无创组及对照组并干预8周。评价生活质量(SRI)、呼吸肌力(MIP、MEP)、呼吸困难(MRC)、运动耐量(6MWD)及肺功能。结果序贯组、锻炼组及无创组SRI总分、6MWD、MRC均显著改变(P均0.05)。结论呼吸肌肉锻练序贯无创通气康复策略对于稳定期重度慢阻肺患者而言临床效果最优,与单用呼吸肌

    2015-01-01

    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.

    Background: Cardiovascular diseases (CVDs) are the greatest cause of death globally, and their reduction is a key public-health target. High blood pressure (BP) affects 1 in 3 people in the United Kingdom, and previous studies have shown that milk consumption is associated with lower BP. Objective: We investigated whether intact milk proteins lower 24-h ambulatory blood pressure (AMBP) and other risk markers of CVD. Design: The trial was a double-blinded, randomized, 3-way–crossover, controlled intervention study. Forty-two participants were randomly assigned to consume 2 × 28 g whey protein/d, 2 × 28 g Ca caseinate/d, or 2 × 27 g maltodextrin (control)/d for 8 wk separated by a 4-wk washout. The effects of these interventions were examined with the use of a linear mixed-model ANOVA. Results: Thirty-eight participants completed the study. Significant reductions in 24-h BP [for systolic blood pressure (SBP): −3.9 mm Hg; for diastolic blood pressure (DBP): −2.5 mm Hg; P = 0.050 for both)] were observed after whey-protein consumption compared with control intake. After whey-protein supplementation compared with control intake, peripheral and central systolic pressures [−5.7 mm Hg (P = 0.007) and −5.4 mm Hg (P = 0.012), respectively] and mean pressures [−3.7 mm Hg (P = 0.025) and −4.0 mm Hg (P = 0.019), respectively] were also lowered. Flow-mediated dilation (FMD) increased significantly after both whey-protein and calcium-caseinate intakes compared with control intake [1.31% (P whey protein and calcium caseinate significantly lowered total cholesterol [−0.26 mmol/L (P = 0.013) and −0.20 mmol/L (P = 0.042), respectively], only whey protein decreased triacylglycerol (−0.23 mmol/L; P = 0.025) compared with the effect of the control. Soluble intercellular adhesion molecule 1 and soluble vascular cell adhesion molecule 1 were reduced after whey protein consumption (P = 0.011) and after calcium-caseinate consumption (P = 0.039), respectively, compared

    2015-08-01

    [Purpose] This study aimed to improve the asymmetrical weight-bearing ratio by applying repetitive sit-to-stand training methods that feature a step-foot position to the paretic-side foot of hemiplegic patients; it sought also to provide the information needed to apply weight-bearing and balance training to hemiplegic patients. [Subjects and Methods] The subjects were divided into two groups: a spontaneous group and a step group. They all performed repetitive sit-to-stand training five times per week for a total of six weeks. The Biodex Balance System, TUG, and 5XSST were used to measure the static and dynamic standing balance of each patient. A foot mat system was used to measure foot pressure. [Results] In the balance measurements, differences in the Overall index, Ant-post index, Med-lat index, Fall risk index, TUG, and 5XSST after training was significantly different between the two study groups. In evaluating foot pressure measurements, we found that the COP (Ant-post), Peak pressure: hind foot, and Contact area: hind foot measurements significantly differed between the groups after the training. [Conclusion] Repetitive sit-to-stand training that involves positioning the non-paretic leg upward can be considered a significant form of training that improves the symmetric posture adjustment and balance of hemiplegic patients following a stroke.

    Objective To explore the effects of different inspiratory rise time in patients recovering from acute exacerbation of chronic obstructive pulmonary disease. Methods 23 patients of acute exacerbation of chronic obstructive pulmonary disease were ventilated with pressure support ventilation at two different inspiratory rise time in turn. The parameters in two conditions of respiration, the vital signs and scales of dyspnea were monitored and compared. Results From the shorter to the longer inspiratory rise time, the tidal volume became bigger,inspiratory time extended,the inspiratory peak flow decreased,airway occlusion pressure increased, the visual analogue score and Borg score of dyspnea exacerbated ( P < 0.05 or < 0.01 ). The visual analogue score and Borg score of dyspnea positively correlated with airway occlusion pressure. The coefficients of correlation were 0. 510 and 0. 640 respectively (both P < 0.05). Conclusion To patients recovering from acute exacerbations of chronic obstructive pulmonary disease,ventilation with pressure support ventilation at the shorter inspiratory rise time decreases the effort of breathing and the scales of dyspnea. Airway occlusion pressure, the visual analogue score and Borg score of dyspnea may be helpful to select appropriate inspiratory rise time.%目的 探讨不同压力上升时间设定对采用压力支持通气模式(PSV)撤机的慢性阻塞性肺疾病(COPD)患者的影响.方法 对23例因呼吸衰竭已经气管插管机械通气并至恢复期的COPD患者进行压力支持通气,采用自身前后对照方法,先后给予较短压力上升时间和较长压力上升时间两种设定,观察患者呼吸形态、生命体征和呼吸困难情况.结果 从较短压力上升时间至较长压力上升时间潮气量增加(0.45±0.08)L vs(0.49±0.10)L、吸气时间延长(0.92±0.13)秒vs(0.49±0.10)秒、吸气峰值流速减小(53.92±8.33)L/min vs(41.69±7.53)L/min、气道闭合压增大(1.88±0.08)mmHg vs

    2011-01-01

    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.

    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

    Full Text Available The article explores the dramas where the city is depicted as a special place determining the dramatization of a piece of work. The city symbolism is analyzed according to the criteria of the archetypal city images formulated by M. Eliade, and J. Lotman. The first part of the article ”A sacral city – Vilnius” deals with historical dramas (“Gediminas’ Dream” by A. Fromas Gužutis, “Kęstutis’ Death” by Maironis, “Radvila the Thunder”, “The Fate of Twilight ”, and “Barbora Radvilaite” by B. Sruoga, “Živilė” by A. Škėma, “Barbora Radvilaitė” by J. Grušas, “The Cathedral” by J. Marcinkevičius, “The Crown and the Sand” by R. Samulevičius, and etc.. In Lithuanian dramaturgy, Vilnius meets all the criteria of an ideal, sacred city. In poetic dramas, Vilnius is described as a superb creation embodying the plenitude of human existence. The second part of the article “The Demonic City” deals with the dramas in which the city symbolism conveys the opposite of a sacred, ideal city – an eccentric and demonic city localized in the “outskirts” of cultural space. This aspect of the city symbolism is analyzed in separate subsections: “The Doomed City” (“The Sea Bells” by Vydūnas, and “The Shackles” by M. Pečkauskaitė, “The Profane City” (the comedy “Vain Attempts” by P. Vaičiūnas, “Julijana” by A. Škėma, “A Spring Song” by B. Sruoga, “The Mammoth Hunt” by K.

    The purpose of this review was to examine the impact of varying degrees of renal insufficiency on pregnancy outcome in women with chronic renal disease. Our search of the literature did not reveal any randomized clinical trials or meta-analyses. The available information is derived from opinion, reviews, retrospective series, and limited observational series. It appears that chronic renal disease in pregnancy is uncommon, occurring in 0.03-0.12% of all pregnancies from two U.S. population-based and registry studies. Maternal complications associated with chronic renal disease include preeclampsia, worsening renal function, preterm delivery, anemia, chronic hypertension, and cesarean delivery. The live birth rate in women with chronic renal disease ranges between 64% and 98% depending on the severity of renal insufficiency and presence of hypertension. Significant proteinuria may be an indicator of underlying renal insufficiency. Management of pregnant women with underlying renal disease should ideally entail a multidisciplinary approach at a tertiary center and include a maternal-fetal medicine specialist and a nephrologist. Such women should receive counseling regarding the pregnancy outcomes in association with maternal chronic renal disease and the effect of pregnancy on renal function, especially within the ensuing 5 years postpartum. These women will require frequent visits and monitoring of renal function during pregnancy. Women whose renal disease is further complicated by hypertension should be counseled regarding the increased risk of adverse outcome and need for blood pressure control. Some antihypertensives, especially angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers, should be avoided during pregnancy, if possible, because of the potential for both teratogenic (hypocalvaria) and fetal effects (renal failure, oliguria, and demise).

    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.

  10. Enhancing host resistance to pressure ulcers: a new approach to prevention.

    Pressure ulcers are notoriously common in spinal-cord-injured patients, in patients with other neurological deficits, in malnourished and severely debilitated patients, and in the frail elderly. Prolonged localized external pressure, coupled with insensitivity to ischemia resulting from neurologic injury, has long been considered the major causal factor. Preventive efforts have focused on the relief of pressure via frequent repositioning and the use of pressure-relieving devices. However, consensus is growing that host factors also play a role in the development of pressure ulcers, the most important in spinal-cord-injured patients being the injury-induced loss of vasomotor control below the level of the lesion, resulting in hypoxemia. Accordingly, pressure ulcers may be prevented not only by reducing external pressure but also by increasing the patient's resistance to pressure, that is, by directly influencing tissue oxygenation. Review of the literature suggests that electrical stimulation increases cutaneous blood flow and promotes the healing of pressure ulcers. Moreover, high-voltage pulsed galvanic stimulation (75 V, 10 Hz) applied to the back at spinal level T6 in spinal-cord-injured persons lying supine on egg-crate mattresses can raise sacral transcutaneous oxygen tension levels into the normal ranges (A. R. Mawson, F. H. Siddiqui, B. J. Connolly, C. J. Sharp, W. R. Summer, and J. J. Biundo, Jr., Paraplegia in press). Randomized controlled trials are needed to determine the efficacy of high-voltage pulsed galvanic stimulation for preventing pressure ulcers in spinal-cord-injured persons and other groups at high risk.

    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.

    Background Pressure ulcer assessment is a crucial step in the nursing of pressure ulcer. Braden Scale is a widely used evaluation tool in current assessment of pressure ulcer,but there are limitations in the risk prediction of pressure ulcer in clinic. Objective To evaluate the value of Braden Scale score combined with acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score in pressure ulcer prediction. Methods 310 patients reported by clinic departments(including ICU,CCU,Department of Cardiovascular Disease, Liver Disease, Oncology, Nephrology, Orthopaedics, Emergency, etc. ) from Traditional Chinese Medicine Hospital in Chongqing from June 2014 to June 2015 were selected as the research objects. Patients'scores of Braden Scale and APACHE Ⅱ were collected. The patients scored not more than 12 in Braden Scale were predicted as high - risk pressure ulcer,while those who scored greater than 12 were low - risk pressure ulcer;the patients scored not more than 12 in Braden Scale and not less than 15 in APACHE Ⅱ were predicted as high - risk pressure ulcer,otherwise they would be taken as low - risk pressure ulcer. The receiver operating characteristic(ROC)curve was predicted by Braden Scale or Braden Scale score combined with APACHE Ⅱ score. The areas under curve ( AUC) of ROC,sensibility,specificity,positive predictive value and negative predictive value were also calculated.

    There are 2 different kinds of chronic otitis media: Otitis media chronica mesotympanalis and otitis media chronica epitympanalis (cholesteatoma). The incidence of chronic otitis media as reported in literature differs in a wide range. The incidence rates vary between 0.45 and 46%. Both, otitis media chronica mesotympanalis and cholesteatoma, lead to eardrum perforation due to lengthy and recurring inflammations. Furthermore, chronic otitis media is characterized by frequently recurring otorrhea and conductive hearing loss.

    It has been shown that during injection of 17 to 20 ml local anesthetics combined with a corticosteroid via the hiatus canalis sacralis that the solution is distributed up to the level of the thoraco-lumbar junction. The indication for therapeutical peridural injection are radicular symptoms as a result of disc herniation, foraminal stenosis as well as neurogenic claudicatio. Contraindications are anticoagulation, local infection as well as suspicion of systemic inflammatory disease of the peripheral nervous system. With proper technique and adequate desinfection, complications and side effects are very rare.

    Objective To explore an improved nerve block method for elder patients undergoing total hip arthroplasty. Methods Fourteen older patients scheduled for total hip arthroplasty from March to June of 2015 were given lumber plexus and sacral plexus nerve block. The block areas were tested with acupuncture. The hemodynamic changes before anesthesia and after skin incision were compared. The maximum change rate of hemodynamic changes during operation was observed. The perioperative adverse reactions and anesthesia satisfaction were also evaluated. Results The cutaneous pain of tensor fasciae latae innervated by superior gluteal nerve, gluteus maximus innervated by inferior gluteal nerve, quadriceps femoris innervated by femoral nerve and hamstrings innervated by sciatic nerve was insensible. There were no significant differences in the changes of systolic blood pressure, diastolic blood pressure, heart rate between after skin incision and pre-anesthesia (P>0.05). The variations of systolic blood pressure, diastolic blood pressure and heart rate were 13.9%± 6.2%, 15.8%± 7.8%, and 14.1%± 4.8%, respectively, which were less than 20%. The surgery was successfully completed in all patients under pure nerve block. There was no use of opiods. The patients didn't present local anesthetics poisoning, and circulating complications such as volatility, respiratory inhibition. The surgeons'satisfaction about anesthetic effect was all 10 points. Conclusion Lumber plexus sacral plexus nerve block is a safe and effective anesthetic technique for total hip arthroplasty. Because of the small sample size, further study is needed.%目的 探讨改良的老年患者人工髋关节置换术的神经阻滞麻醉方法.方法 选取2015年3~6月于我院行全髋关节置换手术的14例老年患者,予腰丛-骶丛神经阻滞麻醉,术前运用针刺法测试麻醉平面,记录术中血流动力学变化、不良反应,评估麻醉效果.结果 臀上神经支配的阔筋膜张肌区域

    The prevalence of chronic constipation is about 16% in adults, and increases with age, especially after 60 years old. Usually, surgical intervention is recommended to patients with long standing intractable constipation, who have undergone various conservative therapies. Lots of surgical procedures have been reported for different kinds of constipation, including slow transit, outlet obstruction, etc. For slow transit constipation, total or subtotal colectomy is commonly used. Merely for the internal rectal prolapse, at least 10 procedures are commonly adopted in clinic. However, no single procedure has been reached a consensus, not to mention the operative indication, principle of procedure selection and outcome assessment. Objectively, the surgical result of chronic constipation is far from perfect. Especially for outlet obstructive constipation, the satisfactory rate is only about 70%. How to enhance the surgical therapeutic effects should be expected on clinical and translation research. Fortunately, sacral neuromodulation therapy and percutaneous tibial nerve stimulation in managing refractory constipation have brought expected outcomes in recent years. Relationship between microbiota of the colonic mucosa and symptoms, and the sensory nerve regulatory mechanism have attracted much attention. We believe that more translational medicine results can be helpful in the future to improve the comprehensive efficacy of constipation.

    Full Text Available Abstract Background Pressure ulcers pose significant negative individual consequences and financial burden on the healthcare system. Prolonged sitting in High Fowler’s position (HF is common clinical practice for older adults who spend extended periods of time in bed. While HF aids in digestion and respiration, being placed in a HF may increase perceived discomfort and risk of pressure ulcers due to increased pressure magnitude at the sacral and gluteal regions. It is likely that shearing forces could also contribute to risk of pressure ulcers in HF. The purpose of this study was to evaluate the effect of a low-tech and time-efficient Trunk Release Manuever (TRM on sacral and gluteal pressure, trunk displacement and perceived discomfort in ambulatory older adults. Method A randomized controlled trial was used. We recruited community-living adults who were 60 years of age and older using posters, newspaper advertisements and word-of-mouth. Participants were randomly allocated to either the intervention or control group. The intervention group (n = 59 received the TRM, while the control group (n = 58 maintained the standard HF position. Results The TRM group had significantly lower mean (SD PPI values post-intervention compared to the control group, 59.6 (30.7 mmHg and 79.9 (36.5 mmHg respectively (p = 0.002. There was also a significant difference in trunk displacement between the TRM and control groups, +3.2 mm and −5.8 mm respectively (p = 0.005. There were no significant differences in perceived discomfort between the groups. Conclusion The TRM was effective for reducing pressure in the sacral and gluteal regions and for releasing the trunk at the point of contact between the skin and the support surface, but did not have an effect on perceived discomfort. The TRM is a simple method of repositioning which may have important clinical application for the prevention of pressure ulcers that may occur as a result of HF.

    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.

    Objective To evaluate the improving reliability and safety of thromboendarterectomy and perioperative management for chronic pulmonary thromboembolism. Methods The clinical data of 12 cases with chronic pulmonary thromboembolism, who underwent thromboendarterec tomy assisted by low flow or circulation arrest with deep hypothermia, were reviewed retrospectively. Results Pulmonary artery pressure decreased 20 to 40 mmHg immediately after surgical procedures in 9 cases. The postoperative pulmonary edema at various degrees happened in 12 cases, among them, 1 died of severe lung infection and pulmonary re-embolism at 19 days postoperation. Computed tomography pulmonary angiography and angiography of 11 cases indicated that the original obstruction of pulmonary artery disappeared. During the follow-up period of 2 months to 5 years, the clinical symptoms and activity was improved. Conclusion Thromboendarterectomy is an effective treatment for chronic pulmonary thromboembolism. The outcome of the surgical procedure needs to be further investigated and followed up regularly according to an evaluative system, because it might be influenced by multiple factors.

    Developing guidelines on a subject as broad as hypertension is difficult, especially when the guidance relates to hypertension in the chronic kidney disease (CKD) population. The Kidney Disease: Improving Global Outcomes Guideline Development Group has applied a rigorous methodology in reviewing all available evidence, and their recommendations are consistent with the evidence-based approach. As a result, the European Renal Best Practice endorses most of its recommendations. However, the Work Group feels that some additional advice could help clinicians in daily practice: (i) individualization of treatment should be taken into account, especially (cardiovascular) co-morbidities, age, gender and race; (ii) side-effects, such as postural dizziness should be monitored closely, particularly in elderly, diabetics and patients with arterial stiffness; (iii) the importance of salt restriction should not be neglected; (iv) although angiotensin-converting enzyme inhibitors (ACE-Is) and angiotensin receptor blocker (ARBs) remain a cornerstone in the management of hypertension, and especially cardiovascular protection, in some particular situations such as in advanced CKD and in patients without proteinuria, their role is less well defined; (v) as most CKD patients need more than one antihypertensive drug to achieve blood pressure control, the specific (renal) (dis)advantages of other classes than ACE-I or ARB should be taken into account.

    Technological advances in recent decades have extended survival time of critically ill hospitalized patients but their unstable physiological state and limited mobility increase their risk for pressure ulcers. On two different days (June 16 and October 20, 2004), pressure ulcer prevalence in patients hospitalized at the São Paulo Hospital, Brazil was assessed. On study day 1, 43 of the 376 inpatients (prevalence, 11.4%) and on study day 2, 35 of 340 inpatients (prevalence, 10.3%) had pressure ulcers. No significant differences in patient or ulcer characteristics between the two study days were observed. Ulcer prevalence was highest among patients in the intensive care unit (average 32.7%). Most patients had one ulcer (61.5%), classified as Stage II (47%), located in the sacral area (47%), and were considered at high risk according to their Braden Scale scores (60% had a score ≤ 11). The results obtained were not unexpected and confirmed the need to improve quality of care by establishing pressure ulcer prevention protocols. Additional studies to optimize prevention efforts and improve the existing evidence-base are necessary, especially in patient care units with high pressure ulcer rates.

    Full Text Available Nitric oxide (NO is thought to play an important role in modulating the inflammatory response by virtue of its ability to affect bloodflow, leukocyte function and cell viability. The objective of this study was to assess the role that NO may play in mediating the mucosal injury and inflammation in a model of chronic granulomatous colitis using two pharmacologically different inhibitors of nitric oxide synthase (NOS. Chronic granulomatous colitis with liver and spleen inflammation was induced in female Lewis rats via the subserosal (intramural injection of peptidoglycan/polysaccharide (PG/PS derived from group A streptococci. Chronic NOS inhibition by oral administration of NG-nitro-L-arginine methyl ester (L-NAME (15 µmol/kg/day or amino-guanidine (AG (15 µmol/ kg/day was found to attenuate the PG/PS-induced increases in macroscopic colonic inflammation scores and colonic myeloperoxidase activity. Only AG -- not L-NAME – attenuated the PG/PS-induced increases in colon dry weight. Both L-NAME and AG significantly attenuated the PG/PS-induced increases in spleen weight whereas neither was effective at significantly attenuating the PG/PS-induced increases in liver weight. Although both L-NAME and AG inhibited NO production in vivo, as measured by decreases in plasma nitrite and nitrate levels, only AG produced significantly lower values (38±3 versus 83±8 µM, respectively, P<0.05. Finally, L-NAME, but not AG, administration significantly increased mean arterial pressure from 83 mmHg in colitic animals to 105 mmHg in the PG/PS+ L-NAME-treated animals (P<0.05. It is concluded that NO may play an important role in mediating some of the pathophysiology associated with this model of chronic granulomatous colitis.

    Full Text Available Ballistic pressure pulse sources are used since late 1990s for the extracorporeal treatment of chronic Enthesitis. Newly indications are found in trigger-point-therapy for the treatment of musculoskeletal disorders. In both applications excellent results without relevant side effects were found in clinical trials. The technical principle of pressure pulse source is based on the same techniques used in air guns. A projectile is accelerated by pressurized air and hits the applicator with high kinetic energy. By this a compression wave travels through the material and induces a fast (4..5μs, almost singular pressure pulse of 2..10 MPa, which is followed by an equally short rarefaction phase of about the same amplitude. It is assumed that the pressure pulse accounts for the biomedical effects of the device. The slower inertial motion of the waveguide is damped by elastic stoppers, but still can be measured several micro seconds after the initial pressure pulse. In order to characterize the pressure pulse devices, field mapping is performed on several radial pressure pulse sources using the fiber optic hydrophone and a polyvinylidenfluorid (PVDF piezoelectric hydrophone. It could be shown that the current standard (IEC 61846 is not appropriate for characterization of ballistic pressure pulse sources.

    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.

    Background To test the hypothesis that chronic administration of angiotensin-(1-7) [Ang-(1-7)] attenuates cardiac hypertrophy in rats in vivo. Methods Coarctation of the suprarenal abdominal aorta was performed in 41 8-week-old male Sprague Dawley rats. Twenty-four hours after the operation, osmotic minipumps were surgically implanted subcutaneously in the rats, which were randomly divided into 3 groups, including a sham-operation group (n=15) receiving infusion with normal saline, a suprarenal aortic coarctation group (n=12), and a suprarenal aortic coarctation group (n=14) with Ang-(1-7) treatment at the dose of 25 μg.kg-1 .h-1. Four weeks later, the systolic and diastolic blood pressures were measured and the left ventricular mass index (LVMI, mg/g) was calculated from the ratio of left ventricular weight to body weight. The concentrations of Ang Ⅱ in the plasma and myocardium were measured by radioimmunoassay, and myocardial interstitial collagen volume fraction (ICVF) was determined by quantitative morphometry of the sections with Picrosirius red staining using an automated image analyzer. Results Suprarenal abdominal aortic coarctation induced a significant increase in carotid artery systolic and diastolic blood pressure, heart weight, LVMI, ICVF, and the concentration of Ang Ⅱ in the myocardium (P<0.01). Chronic administration of Ang-(1-7) attenuated the increase in the heart weight, LVMI, ICVF and left ventricular diastolic end pressure (LVEDP) caused by suprarenal abdominal aortic coarctation (P<0.05). Ang-(1-7) also increased the formerly decreased maximum left ventricular pressure reduction rate (-dP/dtmax) (P<0.05), but had no effect on blood pressure and the concentration of Ang Ⅱ in the myocardium. No difference was noted in plasma concentration of Ang Ⅱ between the 3 groups. Conclusions Ang-(1-7) attenuates cardiac hypertrophy and fibrosis and preserved the impaired left ventricular function induced by left ventricular pressure

    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.
