    Anterior sacral meningoceles (ASM) in Marfan syndrome are rare. They may cause constipation, urinary frequency, dysmenorrhoea, and low back pain or numbness. This report describes bilateral ASM at the level of S1, S2 and S3 in a woman with Marfan syndrome who was admitted to the gynaecology department for evaluation of left lower abdominal pain. The magnetic resonance appearance of the meningoceles is discussed and compared with findings from transvaginal ultrasound and CT. As MRI offers excellent delineation of spinal and pelvic structures, it is the most useful technique available in establishing the diagnosis and planning the treatment of ASM. (orig.)

    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.

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

    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.

  7. Cancer of the breast and anterior sacral meningeal in a patient with Marfan syndrome

    International Nuclear Information System (INIS)

    Introduction. Breast cancer is the most common malignancy of women in the world Western. It is rare below 30 years. Marfan syndrome (MS) is an entity clinically characterized by cardiovascular, ocular and skeletal genetic base. Its prevalence is estimated at 4-6 per 100,000 births. In the literature there are few reports of cancers diagnosed in association with SM, and after a thorough review, we found only two communications association with malformations such as dural sac meningocele. Objective. The aim of this study was to review the literature from communication A case report of a patient with SM in which the age of 24 he diagnosed with breast cancer and a previous sacral meningocele. Case. Female patient 24 years old, with SM, who consulted a tumor of right breast. Was studied with mammography and cytological puncture were positive for malignancy. Local treatment consisted of modified radical mastectomy and chest wall radiotherapy. The pathology corresponded to ductal carcinoma Infiltrating (CDI) NOS 27mm diameter greater final histologic grade II carcinoma in situ solid and cribriform intermediate grade without necrosis greater than 30%; 10 axillary lymph resected, all free of metastases. The dosage of hormone receptors was frankly positive for both estrogen and progesterone. In sum CDI NOS stage IIA. the chest radiograph and bone scan showed no abnormalities and abdominal ultrasound He requested postoperatively revealed an abdominopelvic image 13 x 16 cm. positron abdomen and pelvis confirmed a predominantly cystic mass in the pelvis and abdomen lower. Exploratory laparotomy revealed that the tumor corresponded to a meningocele before and proceeded to peritoneal cyst resection and closure of the sacral gap. At the time of writing, the patient is free and without neurological deficit disease, low adjuvant Tamoxifen for 3 years. Conclusions. The SM as breast cancer in younger women is uncommon. Few cancers have been reported in association with SM. Some of

    A 74-year-old female patient, who was diagnosed with neurofibromatosis type 1 (NF1) at the age of 40, was admitted with complaints of flickering vision and gait disturbance for the last 2 years. On admission, neurological examination revealed mild bilateral hearing loss and ataxia in the limb and trunk. Laboratory tests revealed anti-hepatitis C virus (HCV) antibody positivity and elevated HCV RNA by real-time polymerase chain reaction. The cerebrospinal fluid examination revealed a slightly yellowish appearance with elevated total protein levels. Gradient echo T2*-weighted brain magnetic resonance imaging (MRI) demonstrated a rim of hypointense lesions surrounding the surface of the cerebellum, brainstem, frontal and temporal lobes, and thalamus, which was considered as hemosiderin depositions. From these MRI findings, she was diagnosed as having superficial siderosis of the central nervous system. Cerebral angiography revealed an aneurysm-like dilatation at the bifurcation of the right internal carotid-posterior communicating artery. (99m)Tc-ethyl cysteinate dimer single-photon emission computed tomography revealed hypoperfusion in the bilateral frontal and temporal lobes. Pelvic plain X-ray, pelvic computed tomography, and lumbosacral MRI revealed a sacral defect and an anterior sacral polycystic meningocele communicating with the spinal subarachnoid space. The patient's symptoms gradually worsened, and she died of septic shock because of pyelonephritis at the age of 77. An autopsy was performed; on pathological examination, we did not observe any findings associated with rupture of the aneurysm-like dilatation in the bifurcation of the right internal carotid-posterior communicating artery and cerebral amyloid angiopathy. Because duropathies-a new neurological disease concept-have been implicated as a cause of bleeding in the superficial siderosis, the anterior sacral polycystic meningocele, a type of duropathies, was presumed to be the most probable bleeding

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

    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.

    In this report, we present two cases of 9-year-old children with spina bifida occulta (SBO) of the sacrum, who were diagnosed with sacral fatigue fractures. In both patients, MRI showed a linear signal void and high signal in sacral ala on the short tau inversion recovery sequence. Sacral SBO at the same level of the sacral fracture was observed in each patient on computed tomography images. These lesions healed with rest. This is the first literature reporting cases with sacral stress fractures who had SBO at the same level of fracture. PMID:26196371

    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

    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.

    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.

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

    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. This equilateral triangle will help in determining the location of the sacral hiatus during caudal epidural block. [National J of Med Res 2012; 2(3.000: 272-275

    2016-01-01

    Patients with spinal cord injury (SCI) commonly suffer from neurogenic lower urinary tract dysfunction (NLUTD). Sacral neuromodulation (SNM) offers an alternative in the treatment of detrusor overactivity in patients with NLUTD. We report the cases of three patients with NLUTD due to SCI who received SNM. Due to treatment success, all patients could resume skiing. All suffered from skiing accidents, leading to a decreased effectiveness of SNM. Subsequent evaluation revealed a defect of the impulse generator (IPG) and/or dislocation of the electrodes. Reprogramming or replacement of the IPG or the electrodes resulted in restoration of SNM function. Trauma due to skiing is a potential risk factor for the integrity of SNM. Patients with SNM should be informed about the potential risk of SNM damage by falls and accidents. PMID:26754577

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

    Objective To investigate an alternative procedure for completedenervation of bladder in the supre-cone cord injury to restore the bladder function. Methods Sixteen dogs were included in this study after their spinal cords were transected above the cone. They were divided into 6 groups and performed the rhizotomy of L7 to S3 root in different combination respectively. The bladder and urethra pressure change by electrostimulation during operation and cystometrogram change after operation were tested. Results ①Electrostimulation study: for bladder innervation, S2 was the most important and S1 was secondary. While for urethra invervation, S1 was more important than S2. When the anterior and posterior roots of S1 and S2 were intact with rhizotomy of posterior roots of L7 and S3, stimulated the common or posterior root of S1 and S2, the change of pressure in bladder and urethra was the same. When the anterior roots of S1 and S2 were resected with rhizotomy of posterior roots of L7 and S3, the pressure in bladder and urethra was significant decreased compared to stimulating the corresponding posterior roots. ②Cystometrogram (CMG) study: in the complete deafferented group, resecting the posterior roots of L7 to S3, the bladder became flaccid. While resecting the posterior root of S2 and anterior root of S1 or, resecting the posterior root of S1 and anterior root of S2, combining with rhizotomy of posterior roots of L7 and S3, the CMG curve was similar to the complete deafferented group. In the S1 and S2 intact group, the bladder became spastic. Comclusion Combining rhizotomy of anterior and posterior sacral root in different level has the same effects on bladder as complete deafferentation.%目的 探讨内脊髓损伤后膀胱完全性去神经传入手术的替代方法。方法 健康杂种犬16只经T10平面截瘫后,按L2~S3神经根切断程度的不同,从完全保留到完全切断分成六组,比较术中神经根(总根和后根)电刺激时的

    In a case of partially resected sacral chordoma, the planning target volume (PTV) received 60 Gy and the gross target volume (GTV) 72 Gy using inversely planned, intensity-modulated, radiation therapy (IMRT). IMRT was compared with 3D-conformal radiotherapy (CRT). With IMRT, it was found that dose distribution is more homogeneous within the PTV outside the GTV and allows simultaneous dose escalation within the GTV. The volume of bowel receiving a dose higher than 40 Gy was reduced from 400cc with CRT to 220cc with IMRT. If particle therapy is not available, IMRT seems to be a promising alternative in the treatment of sacral chordomas.

  7. Sacral-neuromodulation CT-guided

    International Nuclear Information System (INIS)

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

    > sagittal > transverse section. The S5 nerve was partially displayed from the starting point to the segment around the posterior sacral foramen. The overall anatomy of the triangular sacral plexus was only revealed in the oblique outward-rotated sagittal section, while 100% of its individual rami,as well as two or three of the adjacent rami, were displayed from their starting points to the anterior border of the piriformis. The abnormalities included 39 sides of morphological change (97.5%), 38 sides of compression (95.0%), 35sides of adhesion (87.5%), 32 sides of displacement (80.0%), 34 sides of shrinkage (85.0%), 6 sides of thickening (15.0%), and 2 sides of abruption (5.0%).Conclusions The 16-slice CT multiplanar reconstruction was able to reveal the overall anatomic features of the SN on the same slice. The section of reconstruction was a crucial factor in determining the display capability of various sacral nerves. This technology was valuable in the diagnosis and management of related diseases.

    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.

    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.

    Full Text Available A 68-year-old female had a three-week history of severe low back pain radiating down the posterior left buttocks and left leg exacerbated by standing and walking. Lumbar spine MRI revealed cystic mass with similar intensity to cerebrospinal fluid located on dorsolateral left side of the sacral spinal canal inferior to the S1 pedicle. There was compression of left exiting S1 and traversing S2 nerve roots. Neurosurgery consult was requested to evaluate the cystic mass in the sacral spinal canal. After clinical evaluation, an unusually located synovial cyst was thought possible. Cyst contents were heterogeneous, suggestive of small hemorrhage and acute clinical history seemed reasonable. Left S1 and partial left S2 hemilaminectomy was performed and an epidural, partially hemorrhagic cyst was removed. There was no obvious connection to the ipsilateral L5-S1 facet joint. Pathology revealed synovial cyst, and the patient’s leg pain was improved postoperatively. This synovial cyst was unusual as it had no connection with the facet joint intraoperatively and its location in the sacral canal was uncommon.

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

    Malignant fibrous histiocytoma (MFH), arising at the site of a sacral chordoma 8 years after massive radiotherapy, is described. Initially, the patient received 7000 rad to the sacral area and, on recurrence, 5 years later, an additional 4000 rad. Two years later, a sacral mass was noted again. Biopsy then revealed MFH; chest x-ray showed multiple lung metastases. A combination chemotherapy, consisting of cyclophosphamide, vincristine, adriamycin (doxorubicin), and DTIC, resulted in a 6 month partial response. Subsequently, the patient died because of progressive metastatic disease. At autopsy, 8 years after diagnosis, both the sacral lesion and the lung metastases proved to be MFH, and no residual chordoma was found.

    Chordomas are rare, low grade, malignant tumours derived from the ectopic remnants of the notochord that line the axial skeleton. They are characterised by their slow growth, long disease course and propensity for local relapse. Furthermore, up to 40% of non-cranial chordomas metastasise. We describe the first reported case of a hand metastasis arising from a conventional sacral chordoma after carbon ion radiotherapy. The common occurrence of distant metastasis with chordomas makes it important to perform a systemic examination, in part because their resection might improve patient prognosis. PMID:25350167

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

    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.

    Full Text Available A 69-year-old female presented as an emergency with atrial fibrillation, which was treated with warfarin. She subsequently developed fresh rectal bleeding and after further investigations a Dukes B adenocarcinoma of the rectum was found. She subsequently underwent a low anterior resection, coloanal anastamosis and a defunctioning ileostomy. Three sterile surgical metallic tacks (pins were inserted into the sacrum to stop brisk bleeding from the presacral venous plexus. Following discharge, she was readmitted with septic shock and a CT scan revealed a presacral fluid collection in the area surrounding the sacral tacks (pins and an anastamotic dehiscence. The patient was not fit for further pelvic surgery to remove the tacks, so an alternative minimally invasive cystoscopic procedure was performed. The sacral tacks (pins were removed by the urologist using a rigid cystoscope and cold cup biopsy forceps. To our knowledge, this is the first reported case in the literature.

    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.

    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.)

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

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

    2006-01-01

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

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

    International Nuclear Information System (INIS)

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

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

    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.

    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.

    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.

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

    International Nuclear Information System (INIS)

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

    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.

    Purpose A sacral chordoma is a rare, slow-growing, primary bone tumor, arising from embryonic notochordal remnants. Radical surgery is the only hope for cure. The aim of our present study is to analyse our experience with the challenging treatment of this rare tumor, to review current treatment modalities and to assess the outcome based on R status. Methods Eight patients were treated in our institution between 2001 and 2011. All patients were discussed by a multidisciplinary tumor board, and an en bloc surgical resection by posterior perineal access only or by combined anterior/posterior accesses was planned based on tumor extension. Results Seven patients underwent radical surgery, and one was treated by using local cryotherapy alone due to low performance status. Three misdiagnosed patients had primary surgery at another hospital with R1 margins. Reresection margins in our institution were R1 in two and R0 in one, and all three recurred. Four patients were primarily operated on at our institution and had en bloc surgery with R0 resection margins. One had local recurrence after 18 months. The overall morbidity rate was 86% (6/7 patients) and was mostly related to the perineal wound. Overall, 3 out of 7 resected patients were disease-free at a median follow-up of 2.9 years (range, 1.6-8.0 years). Conclusion Our experience confirms the importance of early correct diagnosis and of an R0 resection for a sacral chordoma invading pelvic structures. It is a rare disease that requires a challenging multidisciplinary treatment, which should ideally be performed in a tertiary referral center. PMID:24999463

    Chordomas are known as rare primary malign tumours that have formed from primitive notochord remains. Sacral chordomas grow slowly but locally and aggressively. Chordomas are locally invasive and have low tendency to metastasis and have a poor prognosis in long-term follow-up. Metastasis may be seen in a rate of 5–40% of the chordomas. Metastasis of chordomas is common in liver, lung, lymph nodes, peritoneum, and brain. The treatment approaches, including surgery, have been discussed in the literature before. Susceptibility to radiotherapy and chemotherapy is controversial in these tumours. The success of surgical treatment affects survival directly. In this report, we will report a sacral chordoma case in which an intraperitoneal distant metastasis occurred and discuss the surgical approach. PMID:25649759

    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.

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

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

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

    2015-03-01

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

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

    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.

    Lumbo-sacral chordomas are rare skeletal sarcomas that originate from the remnant notochord. There are approximately 35 lumbo-sacral chordomas reported annually in the U.S.A. The understanding of this rare human cancer is limited to observations of its clinical behavior and embryonic link. We performed chromosome and molecular analyses from five surgically harvested chordomas in an effort to document genetic abnormalities and to further understand its tumor biology. Cytogenetically, four of five patients had entirely normal chromosomes. One patient had several abnormalities seen in one of 100 cells including a translocation with breakpoints at bands 5q13 and 7q22, loss of one X chromosome and an extra chromosome 14. There was no evidence of monosomy X or trisomy 14 seen with interphase in situ hybridization using biotin-labeled alpha satellite chromosome specific probes for chromosome 14/22 and X. Telomere integrity is required to protect termini from illegitimate recombination. Typically telomeric reduction occurs in senescent fibroblasts in vivo aging and several human solid tumors. A telomeric probe (TTAGGG){sub 50} was hybridized to genomic DNA isolated from chordoma cells and digested with Hinf I which allows the telomeric DNA to remain intact. The tumor DNA was paired with leukocyte DNA from age-matched controls and revealed telomere elongation in all four patients studied with molecular genetic techniques. Telomerase activity is required to maintain telomere integrity and is not present in normal somatic cells. It is determined by visualizing the sizes of the electrophoresis gel-separated radioactive telomeric fragments assembled during incubation of cytoplasmic extracts containing telomerase. Telomerase activity was detected when compared with HeLa cells, a positive control. In addition, no telomerase activity was detected from the chordoma patient`s fibroblasts.

    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.

  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.

    A 74-year-old man presented with a progressively worsening pain in sacrum and was diagnosed to have a sacral chordoma by biopsy in May, 2004. Percutaneous intratumoral injection with lipiodol-pingyangmycin suspension (LPS) was carried out under image guidance and repeated when the pain in sacrum recurred and the tumor increased. During a 6-year follow-up period, three sessions of this treatment were executed. CT imaging and Karnofsky Performance Score were used to evaluate the size of tumor and quality of life, respectively. The patient was free of pain after each procedure and had a high quality of life with a Karnofsky Performance Score above 80 points. The tumor lesion in sacral area was effectively controlled. No complications were observed. Percutaneous intratumoral injection with LPS under image guidance may be an effective and safe alternative for the patients with sacral chordoma.

  3. Jogger's fracture and other stress fractures of the lumbo-sacral spine

    International Nuclear Information System (INIS)

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

    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.

    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

    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 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.

    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.

    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.)

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

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

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

    Sacral chordoma is a rare spine tumor with a high recurrence rate even after optimal therapy. Previous studies have demonstrated that the PI3K/AKT pathway plays a pivotal role in chordoma, and high expression of pAKT is associated with poor prognosis. Recently, PHLPP was recognized to be a tumor suppressor that targets AKT. We analyzed the expression of PHLPP1 and AKT2 in 37 chordoma samples and 11 fetal nucleus pulposus samples by immunohistochemical staining. Of the chordoma cases, 40.5% (15/37) showed strong cytoplasmic staining (score ≥3) for PHLPP1, which was significantly lower than the 90.9% (10/11) of fetal nucleus pulposus samples (P = 0.004). Conversely, strong immunohistochemical staining for AKT2 was observed in 75.7% (28/37) of chordoma samples, which was significantly higher than 36.4% (4/11) of fetal nucleus pulposus (P = 0.021). Kaplan-Meier survival curves and log-rank test showed that patients with high expression of PHLPP1 experienced longer progression free survival time than those with low PHLPP1 expression (P = 0.011). Further multivariate Cox regression analysis indicated that PHLPP1 expression level and surgical approaches were independent risk factors for chordoma recurrence (P = 0.023 and P = 0.022). However, PHLPP1 expression was not statistically related to patients’ total survival time. Conclusively, our results suggest that PHLPP1 plays a crucial role in sacral chordoma, and may be a promising biomarker for prognosis. Meanwhile, manipulation of PHLPP1 expression is also a potential therapeutic approach for the treatment of sacral chordoma. PMID:26823799

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

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

    International Nuclear Information System (INIS)

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

    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.

    The current report presents a case of a 78-year-old male with sacral chordoma, showing an aggressive clinical course. The patient underwent sacral resection, however, nine months later, multiple metastases were detected by magnetic resonance imaging. The metastases progressed rapidly and 15 months following surgery the patient succumbed to respiratory dysfunction. An autopsy revealed multiple metastases of the lung, liver, heart, kidneys and vertebrae. Pathologically, the tumors did not show proliferation of anaplastic cells or dedifferentiation; however, the metastatic tumor cells were smaller than the primary tumor cells. The Ki-67 labeling indices were <5% in all of the patient’s tumors, therefore, the capacity for cellular proliferation of the tumors was considered to be low. Chordoma in adults are generally slow-growing tumors and are associated with a relatively prolonged course and frequent local recurrences. Therefore, it must be recognized that chordoma may grow rapidly and show an aggressive clinical course, even when the Ki-67 labeling index is low. PMID:24765153

    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.

  10. Modified Kraske Procedure with Mid-Sacrectomy and Coccygectomy for En Bloc Excision of Sacral Giant Cell Tumors

    2014-01-01

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

    Haemangiomas are the most common tumours of infancy and early childhood. They are usually present in the neonate in the first 2 weeks of life. Haemangioma usually involves the head and neck area but less commonly involves the lumbosacral and perineal areas. Involvement of lumbosacral, perineal and other areas with associated anomalies are very rare. We present a neonatal case with extensive superficial haemangioma from the perineum to the neck along with multiple congenital anomalies.

    Congenital anterior urethral diverticulum (CAUD) may be found all along the anterior urethra and may present itself at any age, from infant to adult. Most children with this condition present with difficulty in initiating micturition, dribbling of urine, poor urinary stream, or urinary tract infection. A careful history will reveal that these children never had a good urinary stream since birth, and the telltale sign is a cystic swelling of the penile urethra. In this paper, we present two cases of CAUD that were managed by excision of the diverticulum with primary repair. PMID:26328174

    2015-09-01

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

    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.

    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.)

    Axon collaterals were identified in 21 of 24 preganglionic neurons in the lateral band of the sacral parasympathetic nucleus of the cat. Following the intracellular injection of HRP or neurobiotin the axons from 20 of these neurons were followed and 53 primary axon collaterals were found to originate from unmyelinated segments and from nodes of Ranvier. Detailed mapping done in the five best labeled cells showed bilateral axon collaterals distributions up to 25,000 microm in length with 950 varicosities and unilateral distributions up to 12,561 microm with 491 varicosities. The axon collaterals appeared to be unmyelinated, which was confirmed at EM, and were small in diameter (average 0.3 microm). Varicosities were located mostly in laminae I, V, VII, VIII and X and in the lateral funiculi. Most varicosities were not in contact with visible structures but some were seen in close apposition to Nissl stained somata and proximal dendrites. Varicosities had average minor diameters of 1.3 microm and major diameters of 2.3 microm. Most were boutons en passant while 10-20% were boutons termineaux. EM revealed axodendritic and axoaxonic synapses formed by varicosities and by the axons between varicosities. It is estimated that the most extensive of these axon collaterals systems may contact over 200 spinal neurons in multiple locations. These data lead to the conclusion that sacral preganglionic neurons have multiple functions within the spinal cord in addition to serving their target organ. As most preganglionic neurons in this location innervate the urinary bladder, it is possible that bladder preganglionic neurons have multiple functions.

    Abstract Background The chloroplast-localized ribulose-1, 5-biphosphate carboxylase\\/oxygenase (Rubisco), the primary enzyme responsible for autotrophy, is instrumental in the continual adaptation of plants to variations in the concentrations of CO2. The large subunit (LSU) of Rubisco is encoded by the chloroplast rbcL gene. Although adaptive processes have been previously identified at this gene, characterizing the relationships between the mutational dynamics at the protein level may yield clues on the biological meaning of such adaptive processes. The role of such coevolutionary dynamics in the continual fine-tuning of RbcL remains obscure. Results We used the timescale and phylogenetic analyses to investigate and search for processes of adaptive evolution in rbcL gene in three gymnosperm families, namely Podocarpaceae, Taxaceae and Cephalotaxaceae. To understand the relationships between regions identified as having evolved under adaptive evolution, we performed coevolutionary analyses using the software CAPS. Importantly, adaptive processes were identified at amino acid sites located on the contact regions among the Rubisco subunits and on the interface between Rubisco and its activase. Adaptive amino acid replacements at these regions may have optimized the holoenzyme activity. This hypothesis was pinpointed by evidence originated from our analysis of coevolution that supported the correlated evolution between Rubisco and its activase. Interestingly, the correlated adaptive processes between both these proteins have paralleled the geological variation history of the concentration of atmospheric CO2. Conclusions The gene rbcL has experienced bursts of adaptations in response to the changing concentration of CO2 in the atmosphere. These adaptations have emerged as a result of a continuous dynamic of mutations, many of which may have involved innovation of functional Rubisco features. Analysis of the protein structure and the functional implications of such mutations put forward the conclusion that this evolutionary scenario has been possible through a complex interplay between adaptive mutations, often structurally destabilizing, and compensatory mutations. Our results unearth patterns of evolution that have likely optimized the Rubisco activity and uncover mutational dynamics useful in the molecular engineering of enzymatic activities.

    Full Text Available OBJETIVO: Relatar o caso de uma criança com síndrome de Currarino diagnosticada após avaliação por episódios recorrentes de infecção urinária. DESCRIÇÃO DE CASO: Menina branca de dois anos, única filha de pais hígidos e sem história familiar de defeitos congênitos. A criança nasceu com imperfuração anal e com fístula retovestibular diagnosticadas no primeiro dia de vida. Por volta dos sete meses, começou a apresentar episódios recorrentes de infecção urinária, estabelecendo-se o diagnóstico de bexiga neurogênica. Na mesma ocasião, foi constatada a presença de agenesia parcial do sacro. A avaliação pela tomografia computadorizada e ressonância nuclear magnética de coluna identificou presença de fístula coincidente com a fosseta da transição lombo-sacral, observada ao exame físico; amputação da porção inferior da medula, com diminuição do número de raízes nervosas da cauda equina e massa pré-sacral de aspecto lipomatoso. Esta foi confirmada durante a cirurgia de correção do ânus imperfurado. A criança não apresentava outras dismorfias e a avaliação radiológica dos pais não identificou anormalidades sacrais. COMENTÁRIOS: A síndrome de Currarino é uma doença genética autossômica, dominante e rara caracterizada pela tríade formada por atresia anal, agenesia parcial do sacro e tumoração pré-sacral. Inclui teratomas, meningoceles, cistos entéricos e lipomas, como observado em nossa paciente. Crianças apresentando anormalidades anorretais deveriam ser sempre cuidadosamente avaliadas quanto à presença da síndrome de Currarino. A agenesia parcial do sacro é um forte indicativo da doença.OBJECTIVE: To report a patient with Currarino syndrome diagnosed after evaluation for recurrent urinary infections.

    Objective: This study retrospectively evaluated the efficacy and toxicity of particle therapy using carbon ions or protons for primary sacral chordomas. Methods: We evaluated 23 patients with primary sacral chordoma treated with carbon ion therapy (CIT) or proton therapy (PT) between July 2005 and June 2011 at the Hyogo Ion Beam Medical Center, Hyogo, Japan. The median patient age was 72 years. 14 patients were treated with 70.4 Gy equivalents (GyE) in 16 fractions and 9 were treated with 70.4 GyE in 32 fractions. CIT was used for 16 patients, and PT was used for 7 patients. Results: The median follow-up period was 38 months. At 3 years, local control (LC), overall survival (OS) and progression-free survival (PFS) for all patients were 94%, 83% and 68%, respectively. The log-rank test revealed that male sex was significantly related to better PFS ( p = 0.029). No other factors, including dose fractionation and ion type, were significant for LC, OS or PFS. In nine patients, ≥Grade 3 acute dermatitis was observed, and ≥Grade 3 late toxicities were observed in nine patients. The 32-fraction protocol reduced severe toxicities in both the acute and late phases compared with the 16-fraction protocol. Conclusion: Particle therapy for patients with sacral chordoma showed favourable LC and OS. Severe toxicities were successfully reduced by modifying the dose fractionation and treatment planning in the later treatment era. Thus, this therapeutic modality should be considered useful and safe. Advances in knowledge: This is the first study including both CIT and PT for sacral chordomas. PMID:24288399

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

    Objective:To 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.

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

  11. Cytopathological Dilemma of Anaplastic Sacral Chordoma with Radiological and Histological Corroboration

    Full Text Available Chordoma is a relatively rare locally invasive and potentially malignant tumor of fetal notochord origin, affecting the axial skeleton. Cytopathological diagnosis of chordoma is favored by the presence of characteristic physaliphorous cells, bearing abundant foamy cytoplasm dispersed in a myxoid matrix. Anaplastic chordoma or dedifferentiated chordoma, an even rarer variant, can cause a diagnostic confusion with chondrosarcoma from the cytopathological point of view, with similar chondromyxoid matrix and atypical cells. Hence, chordoma bearing anaplastic features needs to be identified and should be distinguished from chondrosarcoma on aspiration cytopathology. We present a case of anaplastic sacral chordoma in a man 59 years of age, causing extensive destruction of sacrum and invading the paravertebral tissues as evidenced by radiology. Fine needle aspiration cytopathology revealed few large pleomorphic hyperchromatic cells, admixed with characteristic physaliphorous cells and myxoid matrix. The cytopathological diagnosis has been confirmed by histopathology and immunohistochemistry. Since anaplastic chordoma bears an unfavorable prognosis, it should be suspected on preoperative aspiration cytopathology. Clinicoradiological correlation along with histopathological and immunohistochemical confirmation is necessary subsequently.

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

    Anterior hip pain is a common complaint with many possible causes. Apophyseal avulsion and slipped capital femoral epiphysis should not be overlooked in adolescents. Muscle and tendon strains are common in adults. Subsequent to accurate diagnosis, strains should improve with rest and directed conservative treatment. Osteoarthritis, which is diagnosed radiographically, generally occurs in middle-aged and older adults. Arthritis in younger adults should prompt consideration of an inflammatory cause. A possible femoral neck stress fracture should be evaluated urgently to prevent the potentially significant complications associated with displacement. Patients with osteitis pubis should be educated about the natural history of the condition and should undergo physical therapy to correct abnormal pelvic mechanics. "Sports hernias," nerve entrapments and labral pathologic conditions should be considered in athletic adults with characteristic presentations and chronic symptoms. Surgical intervention may allow resumption of pain-free athletic activity. PMID:10537384

    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.)

    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

    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

    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.

    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.

    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.

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

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

Twenty-six patients with surgical treatment were analyzed retrospectivly. No intraop-erative death occurred. After average 3. 5 years follow-up, 7 patients had recurred, with a recurrence rate of 26. 9%. The most recurrence was 4 times in one patients. One patient had pulmonary metastasis, and 2 patients died. The typical "Physaliphorous cell" could be found in the oncologic examination in all patients. In conclusion, the early clinical manifestation of sacral chordoma is not typical, so the CT and MR should be paid for more attention. Complete resection of tumor are an effective way to treat the sacral chordoma. Combine with intraoperative chemothery and postoperative adjuvant radiotherapy can reduce the tumor recurrence rate, prolong the survival time, and improve life quality of patients.

    Chordoma is a rare and low-malignant neoplasm which is considered to arise from notochord remnants. Due to its large resistance to chemotherapy and radiotherapy, surgical resection so far is the prior treatment for chordoma. However, the recurrence rate is high even after complete surgical resection. Recently, targeted cancer therapy has been demonstrated to be effective in several other tumors, while the related research on chordoma is rare. Mitogen-activated protein kinase signaling pathway is acknowledged to participate in tumor development, in which Raf-1 and extracellular regulated protein kinase 1/2 (ERK1/2) play vital roles. In this study, we evaluated the expression of Raf-1 and ERK1/2 by immunohistochemical staining in 42 chordoma tissue and 16 distant normal tissue. Moreover, we also investigated the correlations of Raf-1 and ERK1/2 expression with clinical features in sacral chordoma. Expression of Raf-1 and ERK1/2 was both significantly higher in sacral chordoma tissue than distant normal tissue (P = 0.008, P = 0.019). Raf-1 positive expression was related to surrounding muscle invasion (P = 0.032) and chordoma recurrence (P = 0.002), but the results did not indicate any association with patients’ age, gender, tumor size and location. ERK1/2 was associated with tumor size (P = 0.044) instead of other clinical factors (P > 0.05). Spearman correlation test showed close relation between ERK1/2 and Raf-1 (P = 0.001, r = 0.518). Kaplan–Meier survival Curve and log-rank test showed that Raf-1 positive expression was associated with shorter continuous disease-free survival time (CDFS) (P = 0.001), while ERK1/2 had no relation to CDFS (P = 0.961). Conclusively, Raf-1 may be an important biomarker in predicting the prognosis of chordoma patients. PMID:25755752

    Full Text Available Objetivo: apresentar os aspectos clínicos, diagnósticos e terapêuticos de pacientes portadores de válvula da uretra anterior. Descrição: em dois neonatos, o diagnóstico presuntivo de patologia obstrutiva do trato urinário foi sugerido pela ultra-sonografia realizada no período pré-natal, confirmando-se o diagnóstico de válvula de uretra anterior pela avaliação pós-natal. Os pacientes foram submetidos a tratamento cirúrgico paliativo, com vesicostomia temporária e, posteriormente, definitivo, pela fulguração endoscópica das válvulas. Ambos evoluíram com função renal normal. Comentários: a válvula da uretra anterior é anomalia rara que deve ser considerada em meninos com quadro radiológico pré-natal sugestivo de obstrução infravesical, secundariamente à hipótese mais comum de válvula da uretra posterior. Ressaltamos a utilização da vesicostomia como derivação urinária temporária nestes casos, prevenindo potenciais complicações pela manipulação da uretra do recém-nascido.Objective: to discuss clinical signs, diagnostic tools and therapeutics of anterior urethral valves, an obstructive anomaly of the urinary system in males. Description: signs of urinary tract obstruction were identified on pre-natal ultrasound in two male fetuses and the diagnosis of anterior urethral valves was made through post-natal evaluation. As an initial treatment, vesicostomy was performed in both patients. Later, the valves were fulgurated using an endoscopic procedure. During the follow-up period both patients presented normal renal function. Comments: anterior urethral valves are a rare form of urethral anomaly that must be ruled out in boys with pre-natal ultrasound indicating infravesical obstruction. Vesicostomy used as an initial treatment rather than transurethral fulguration may prevent potential complications that can occur due to the small size of the neonatal urethra.

    Full Text Available Epidermoid cysts are benign slow growing more often extra-axial tumors that insinuate between brain structures, we present the clinical, imaging, and pathological findings in 35 years old female patients with atypical epidermoid cysts which was situated anterior, middle & posterior cranial fossa. NCCT head revealed hypodense lesion over right temporal and perisylvian region with extension in prepontine cistern with mass effect & midline shift and MRI findings revealed a non-enhancing heterogeneous signal intensity cystic lesion in right frontal & temporal region extending into prepontine cistern with restricted diffusion. Patient was detoriated in night of same day of admission, emergency Fronto-temporal craniotomy with anterior peterousectomy and subtotal resection was done. The histological examination confirms the epidermoid cyst. The timing of ectodermal tissue sequestration during fetal development may account for the occurrence of atypical epidermoid cysts.

    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.

    2007-01-01

    Anterior impingement is a common problem in dancers occurring primarily secondary to the repetitive forced ankle dorsiflexion inherent in ballet. Symptoms generally occur progressively and may respond to conservative treatment including addressing biomechanical faults that contribute to the problem. As impingement progresses, movements essential to ballet may become impossible and arthroscopic ankle surgery is often effective for both diagnosis and treatment, allowing athletes to return to da...

    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.

    Case 1: The 61-year-old woman developed uterine cancer at age 50. Radiation therapy was initiated to the pelvic lumen from both anterior and posterior sides with a total dose of 21,000 rads. Radiation ulcerative enterocolitis and dermatitis revealed at the end of the therapy. At age 52 (2 years after radiation), she noticed muscle weakness and dysesthesia of the lower legs. These symptoms progressed and amyotrophy of the legs appeared. At age 54 (4 years after radiation), she became unable to walk. Case 2: The 51-year-old woman developed uterine cancer at age 40. Postoperative radiation was initiated by the same dose and the same way as in Case 1 and she suffered from radiation dermatitis. At age 49 (9 years after radiation), she noticed dysesthesia of the right toe, which gradually spread to another side. Ten years after radiation, she began to note weakness in dorsiflexion of feet. Case 3: The 69-year-old woman developed uterine cancer at age 67. Radiation (Linac 4,000 rads, Ralstron 2,000 rads) was performed for 3 months into the pelvic lumen. Two years later, she noted dysesthesia and weakness of her legs. These symptoms progressed gradually. In these 3 cases, EMG showed neurogenic changes, suggesting peripheral nerve lesions. Nerve conduction velocities were decreased. Nerve and muscle biopsies revealed neurogenic changes. No abnormal findings were detected by spinal X-rays and myelography. The neurological findings of these patients were compatible with the lumbo-sacrol plexus injuries apparently due to late radiation effect. (J.P.N.).

  5. The influence of sacral morphology on the existence of secure S1 and S2 transverse bone corridors for iliosacroiliac screw fixation.

    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.

    Electrical stimulation and other modalities are recommended for treatment of pressure ulcers in spinal cord injury patients but their use may be limited by clinical contraindications such as necrosis and infection. Acoustic pressure wound therapy can be used to address infection and has no known contraindications related to wound status. A retrospective nonconsecutive study was conducted involving five inpatients with sacral pressure ulcers and compromised mobility (spinal cord injury, ventilator/mobility dependency, or persistent vegetative state) treated with acoustic pressure wound therapy three times per week, 4 to 6 minutes per session, for 5 weeks to 5.5 months. Acoustic pressure wound therapy was administered until necrotic tissue was removed, granulation was complete, drainage resolved to moderate levels, and wound size was compatible with indications for high-voltage electrical stimulation. Within 1 to 4 weeks of starting acoustic pressure wound therapy, four out of five wounds with substantial yellow slough or eschar demonstrated 100% granulation tissue and wound area and volume decreased 71% to 97% and 75% to 99%, respectively. Subsequent treatments included electrical stimulation alone (three patients) or in conjunction with negative pressure wound therapy (one patient), and silver foam (one patient). Acoustic pressure wound therapy was found to be an effective option in preparing wounds for subsequent therapy. PMID:18716342

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

    6 month of follow-up respectively. The mean preoperative loss of the anterior vertebral height improved from 44.7% to 18.4% immediate postoperatively and was 17.5% at final follow-up at 1 year. The means preoperative kyphus angle also improved from 23.3° to 9.3° immediately after surgery, which deteriorated to 11.5° at final follow-up. One patient developed deep wound infection at the operative site as well as flap necrosis, which needed debridement and removal of hardware. Five patients had bed sore in the sacral region, which healed uneventfully. In tubercular spine (n=25 group, mean operating time was approximately 45 minutes less than traumatic group. The mean intraoperative blood loss was 1100 ml (750-2200 ml. The mean preoperative kyphosis was corrected from 55° to 23°. Wound healing occurred uneventful in 23 cases and wound dehiscence occurred in only 2 cases. Nine out of 11 cases with paraplegia showed excellent neural recovery while 2 with panvertebral disease showed partial neural recovery. None of the patients in both groups required intensive unit care. Conclusions: Simultaneous exposure of both posterior and anterior column of the spine for posterior instrumentation and anterior decompression and fusion in single stage by extra pleural retroperitoneal approach by "T" incision in thoracolumbar spinal lesions is safe, an easy alternative with reduced morbidity as chest and abdominal cavities are not violated, ICU care is not required and diaphragm is not cut.

  9. Anterior chest wall examination reviewed

    2011-09-01

    Full Text Available Anterior chest wall involvement is not infrequently observed within inflammatory arthropaties, particularly if one considers seronegative spondiloarthritides and SAPHO syndrome. Physical examination is unreliable and conventional X-rays analysis is an unsatisfactory tool during diagnostic work-up of this region. Scintigraphic techniques yield informations both on the activity and on the anatomical extent of the disease while computerized tomography visualize the elementary lesions, such as erosions, which characterize the process. Moreover, when available, magnetic resonance imaging couple the ability to finely visualize such lesions with the possibility to show early alterations and to characterize the “activity” of the disease, presenting itself as a powerful tool both for diagnosis and follow-up. This review briefly shows the applications of imaging techniques for the evaluation of the anterior chest wall focusing on what has been done in the SAPHO syndrome which can be considered prototypical for this regional involvement since it is the osteo-articular target mainly affected by the disease.

    Full Text Available Introduction The aim of this paper was to present methods of placement of artificial anterior teeth in edentulous individuals. The following review takes account of the majority of papers published during the last 100 years. The review has been divided into sections regarding the method used to determine the position of artificial anterior teeth. Geometric aspect Gysi (1895-1920 produced the first scientific theory about the position of artificial anterior teeth. Physiognomic theory The aim of this theory is to find the most natural position for artificial anterior teeth for each individual. Camper's "face angle" as a physiognomic criterion, has been introduced in papers of Wehrli (1961, Marxhors (1966, Tanzer (1968, Lombardi (1973. Esthetic aspect Important names in the field of dental esthetics are: Schön and Singer (1961, Arnheim (1965, Krajiček (1969, Tanzer (1968, Lombardi (1973, Goldstein (1976. They have introduced principles of visual aspects for selection of contours, dimension and position of artificial anterior teeth. Constitution aspect Flagg (1880, Williams (1913 and Hrauf (1957, 1958, have considered body constitution and individual characteristics regarding position of artificial anterior teeth. Physiological theory In 1971, Marxhors pointed to the fact that the position of artificial teeth corresponds with the function of the surrounding soft tissue and from the aspect of physiognomy as well. Phonetic aspect According to Silverman (1962 artificial anterior teeth are nearest when we pronounce the sound "S". Cephalometrical research Rayson (1970, Watson (1989, Strajnić Lj. (1999, Bassi F. (2001 have presented cephalometric radiographic analyses of natural anterior teeth compared with cephalometric radiographic analyses of artificial anterior teeth. A review of dental literature shows several factors suggesting modalities which should determine the position of artificial anterior teeth. Numerous methods have been designed for

    Full Text Available Herniation of the anterior lens capsule is a rare abnormality in which the capsule bulges forward in the pupillary area. This herniation can be mistaken for an anterior lenticonus where both the capsule and the cortex bulge forward. The exact pathology behind this finding is still unclear. We report the clinical, ultrasound biomicroscopy (UBM and histopathological findings of a case of herniation of the anterior lens capsule. UBM helped to differentiate this entity from anterior lenticonus. Light microscopy revealed capsular splitting suggestive of capsular delamination and collection of fluid (aqueous in the area of herniation giving it a characteristic appearance.

    Full Text Available Toxic anterior segment syndrome (TASS is a sterile intraocular inflammation caused by noninfectious substances, resulting in extensive toxic damage to the intraocular tissues. Possible etiologic factors of TASS include surgical trauma, bacterial endotoxin, intraocular solutions with inappropriate pH and osmolality, preservatives, denatured ophthalmic viscosurgical devices (OVD, inadequate sterilization, cleaning and rinsing of surgical devices, intraocular lenses, polishing and sterilizing compounds which are related to intraocular lenses. The characteristic signs and symptoms such as blurred vision, corneal edema, hypopyon and nonreactive pupil usually occur 24 hours after the cataract surgery. The differential diagnosis of TASS from infectious endophthalmitis is important. The main treatment for TASS formation is prevention. TASS is a cataract surgery complication that is more commonly seen nowadays. In this article, the possible underlying causes as well as treatment and prevention methods of TASS are summarized.

    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.

    Sacral chordoma is a primarily benign tumor with a high tendency to recur. A correct definition of tumor volume is a significant prognostic factor. We compared the value of CT and MRI in diagnosing a sacral chordoma. 31 patients with a histologically proven sacral chordoma were included in this study. Following parameters were analyzed by two independent radiologists: septation, signs of blood and ossification in the tumor tissue, contrast enhancement, maximal tumor diameter, infiltration of the soft tissue, the dural salc and the cauda equina and multifocality. In CT all chordomas showed a hypodensity to the normal tissue and in MRI a hyperintensity on T2w images with a low level of contrast enhancement. On the basis of the more precise soft tissue contrast of MRI compared with CT, MRI was significantly more accurate in all tested parameters (p <0.05) besides in detecting tumor ossification. In CT tumor volume was frequently underestimated. MRI in sacral chordoma is an essential tool in the pretherapeutic diagnostic regimen and in a state of relapse. (orig.) [German] Das sakrale Chordom ist ein primaer gutartiger Tumor des Knochenskeletts. Eine korrekte und ausreichende Tumorvolumendefinition zur Therapieplanung ist ein entscheidender Prognoseparameter aufgrund der hohen Rate an Rezidiven. Wir untersuchten die Wertigkeit der CT und MRT in der Diagnostik des sakralen Chordoms. Mittels CT und MRT wurden bei 31 Patienten mit histologisch gesichertem sakralem Chordom Septierung, Ossifikation, Zeichen einer Einblutung, die Kontrastmittelaufnahme des Tumors, die maximale axiale Tumorausdehnung, Weichteilinfiltration, Infiltration des Duralsackes, der Cauda equina und eine Multifokalitaet durch 2 unabhaengige Radiologen untersucht und bewertet. Alle Chordome zeigten in der CT nativ ein hypodenses und in der MRT ein T2w-hyperintenses Verhalten mit nur maessiger Kontrastmittelaufnahme.

    Using new /sup 125/I brachytherapy techniques, we were able to deliver safely a tumor volume dose of 16,000 rads to a previous irradiated, large, recurrent sacral chordoma by means of the intraoperative interstitial implantation of 229 low activity /sup 125/I seeds and 40,000 rads to a previously irradiated, small, recurrent clival chordoma by means of the transnasal needle implantation of two high activity /sup 125/I seeds. Iodine-125 brachytherapy was followed by regression of tumor, lessening of symptoms, and bony recalcification in both cases.

    Background The aims of this study were to investigate the clinical characteristics of patients with combined anterior instability and superior labrum from anterior to posterior (SLAP) lesions, and to analyze the effect of concomitant SLAP repair on surgical outcomes. Methods We retrospectively reviewed patients who underwent arthroscopic stabilization for anterior shoulder instability between January 2004 and March 2013. A total of 120 patients were available for at least 1-year follow-up. Forty-four patients with reparable concomitant detached SLAP lesions (group I) underwent combined SLAP and anterior stabilization, and 76 patients without SLAP lesions (group II) underwent anterior stabilization alone. Patient characteristics, preoperative and postoperative pain scores, Rowe scores, and shoulder ranges of motion were compared between the 2 groups. Results Patients in group I had higher incidences of high-energy trauma (p = 0.03), worse preoperative pain visual analogue scale (VAS) (p = 0.02), and Rowe scores (p = 0.04). The postoperative pain VAS and Rowe scores improved equally in both groups without significant differences. Limitation in postoperative range of motion was similar between the groups (all p-value > 0.05). Conclusions Anterior instability with SLAP lesion may not be related to frequent episodes of dislocation but rather to a high-energy trauma. SLAP fixation with anterior stabilization procedures did not lead to poor functional outcomes if appropriate surgical techniques were followed. PMID:27247742

To report our experience with creating a skin-central nervous system-bladder reflex arc with intradural lumbar to sacral motor root microanastomosis to restore bladder/bowel function in spina bifida patients. Methods. Urinary/bowel changes from baseline to three years were evaluated with questionnaires, voiding diaries, urodynamics (UDS, and renal function studies. Treatment response was defined as CIC ≤ once/day with stable renal function, voiding efficiency > 50%, and no worsening of motor function. Results. Of 13 subjects (9 female, median age 8 years, 3 voided small amounts at baseline, one voided 200 cc (voiding efficiency 32%, 4/13 reported normal bowels, and 2/13 were continent of stool. Postoperatively, all had transient lower extremity weakness; one developed permanent foot drop. Over three years, renal function remained stable and mean maximum cystometric capacity (MCC increased (P=0.0135. In the 10 that returned at 3 years, 7 were treatment responders and 9 had discontinued antimuscarinics, but most still leaked urine. Only 2/8 with baseline neurogenic detrusor overactivity (NDO still had NDO, all 3 with compliance <10 mL/cm H2O had normalized, 7/10 considered their bowels normal, 5/10 were continent of stool, and 8/10 would undergo the procedure again. Conclusion. Lumbar to sacral nerve rerouting can improve elimination in spina bifida patients. This trial is registered with ClinicalTrials.gov NCT00378664.

    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.

    Full Text Available Aim: to study influence of traction therapy in a pulse mode in a complex with electrotherapy on a condition of blood circulation of the bottom extremities and level of a metabolic exchange. Material and methods. There had been examined 120 patients with a lumbar and sacral dorsopathy aged from 22 to 69 years (middle age of 49,5 years with prescription of a disease from 1 to 5 years, among them men of 34,2%, women of 65,8%. 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.

    The proposed skiing injury mechanism that suggests a quadriceps muscle contraction can contribute to anterior cruciate ligament rupture was biomechanically investigated. The effect of quadriceps muscle force on a knee specimen loaded to anterior cruciate ligament failure during anterior tibial translation was studied in a human cadaveric model. In both knees from six donors, average age 41 years (range, 31 to 65), the joint capsule and ligaments, except the anterior cruciate ligament, were cut. The quadriceps tendon, patella, patellar tendon, and menisci were left intact. One knee from each pair was randomly selected to undergo destructive testing of the anterior cruciate ligament by anterior tibial translation at a displacement rate of 30 mm/sec with a simultaneously applied 889 N quadriceps muscle force. The knee flexion during testing was 30 degrees. As a control, the contralateral knee was loaded correspondingly, but only 5 N of quadriceps muscle force was applied. The ultimate load for the knee to anterior cruciate ligament failure when tested with 889 N quadriceps muscle force was 22% +/- 18% higher than that of knees tested with 5 N of force. The linear stiffness increased by 43% +/- 30%. These results did not support the speculation that a quadriceps muscle contraction contributes to anterior cruciate ligament failure. In this model, the quadriceps muscle force protected the anterior cruciate ligament from injury during anterior tibial translation.

    The clinical features of 290 children with anterior uveitis are presented. The vast majority suffered from chronic uveitis. Specific uveitis entities in children include the syndrome of 'chronic iridocyclitis' in girls, heterochromic cyclitis, and pars planitis. Systemic associations include sarcoidosis, the Vogt-Harada-Koyanagi syndrome, and the seronegative arthritides (juvenile chronic arthritis, juvenile ankylosing spondylitis, psoriatic arthritis, and rarely Reiter's and Beçet's syndromes). Children with a pauciarticular onset of juvenile chronic arthritis, especially when combined with positive findings for antinuclear antibody, are at particular risk of developing chronic anterior uveitis. Most cases of chronic anterior uveitis can be controlled with topical corticosteroids. Those that are resistant to both topical and systemic corticosteroids may have to be treated with chlorambucil. The operation of lensectomy is a great advance in the management of complicated cataract. Secondary glaucoma is the most devastating complication of chronic anterior uveitis in children and responds poorly to therapy.

    The development of corneal and anterior segment optical coherence tomography (OCT) technology has advanced rapidly in recently years. The scan geometry and imaging wavelength are both important choices to make in designing anterior segment OCT systems. Rectangular scan geometry offers the least image distortion and is now used in most anterior OCT systems. The wavelength of OCT light source affects resolution and penetration. An optimal choice of the OCT imaging wavelength (840, 1,050, or 1,310 nm) depends on the application of interest. Newer generation Fourier-domain OCT technology can provide scan speed 100-1000 times faster than the time-domain technology. Various commercial anterior OCT systems are available on the market. A wide spectrum of diagnostic and surgical applications using anterior segment OCT had been investigated, including mapping of corneal and epithelial thicknesses, keratoconus screening, measuring corneal refractive power, corneal surgery planning and evaluation in LASIK, intracorneal ring implantation, assessment of angle closure glaucoma, anterior chamber biometry and intraocular lens implants, intraocular lens power calculation, and eye bank donor cornea screening.

    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

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

    The mediastinum is located from the thoracic inlet to the diaphragm between the left and right pleural cavities and contains vital structures of the circulatory, respiratory, digestive, and nervous system. Over the years, since there are no fascial or anatomic planes, anatomists and radiologists have suggested various schemes for subdividing the mediastinum and several anatomical and radiological classifications of the mediastinum are reported in the literature. The most popular of these scheme divides medistinum, for purposes of description, into two parts: an upper portion, above the upper level of the pericardium, which is named the superior mediastinum; and a lower portion, below the upper level of the pericardium. For clinical purposes, the mediastinum may be subdivided into three major areas, i.e. anterior, middle, and posterior compartments. The anterior mediastinum is defined as the region posterior to the sternum and anterior to the heart and brachiocephalic vessels. It extends from the thoracic inlet to the diaphragm and contains the thymus gland, fat, and lymph nodes. This article will review surgical anatomy of the anterior mediastinum and will focus on the surgical approch to anterior mediastinum and thymic diseases.

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

    International Nuclear Information System (INIS)

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

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.

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

    1997-08-01

    In the maxillary anterior region, the gingival labial margin position is an important parameter in the achievement of an ideal smile. The relationship between the periodontium and the restoration is critical if gingival health and esthetics are to be achieved. Periodontal therapy is a necessary and useful adjunct when any anterior restoration is undertaken. Anterior surgical crown lengthening may be undertaken to avoid restorative margin impingement on the biologic width. Crown lengthening is also used to alter the gingival labial profiles. This article discusses the esthetic parameters of ideal gingival labial positions and presents a classification of crown-lengthening procedures and the procedure for a two-stage crown-lengthening technique. The two-stage crown-lengthening technique is surgically precise because healing is predictable.

    Full Text Available Thymolipoma is a rare benign tumor of anterior mediastinum, described by Lange in 1916. 1 Less than 200 cases have been reported worldwide. 2 It accounts for 2% to 9% of thymic tumours. 3 We report a case of thymolipoma in a 37 year s old male patient, who pre sented with cough, dys p nea, chest pain for 2 months. CT THORAX revealed a large anterior mediastinal mass extending in to right hemithorax arising from thymus gland, with multiple areas of fat density, no significant mediastinal adenopathy, complete collap se of right middle and lower lobe suggestive of thymolipoma. CT guided biopsy suggestive of thymic neoplasm. The tumour was removed enbloc through surgery. Histopathological examination of large mass lesion confirmed thymolipoma. We report this case to emp hasize the importance of considering thymolipoma as a differential diagnosis of anterior mediastinal mass, although rare.

With early recognition and aggressive systemic therapy, prognosis for resolution is good. The diagnosis of underlying autoimmune disease involves a multidisciplinary approach.Case report: A 42-year-old African American female presented to the Eye Clinic at the San Francisco Veteran Affairs Medical Center, with a tremendously painful left eye, worse on eye movement, with marked injection of conjunctiva. There was mild swelling of the upper eyelid. Visual acuity was unaffected, but there was a mild red cap desaturation. The posterior segment was unremarkable. The initial differential diagnoses included anterior scleritis and orbital inflammatory disease. Oral steroid treatment was initiated with rapid resolution over a few days. Orbital imaging was unremarkable, and extensive laboratory work-up was positive only for antinuclear antibodies. The patient was diagnosed with idiopathic diffuse, nonnecrotizing anterior scleritis and has been followed for over 5 years without recurrence. The rheumatology clinic monitors the patient closely, as suspicion remains for potential arthralgias including human leukocyte antigen-B27-associated arthritis, lupus-associated arthritis, seronegative rheumatoid arthritis, recurrent juvenile idiopathic arthritis, and scleroderma, based on her constitutional symptoms and clinical presentation, along with a positive anti-nuclear antibody lab result.Conclusion: Untreated anterior scleritis can progress to formation of cataracts, glaucoma, uveitis, corneal melting, and posterior segment disease with significant risk of vision loss. Patients with anterior scleritis must be aggressively treated with systemic anti

    Full Text Available Congenital coronary artery anomalies are uncommon. Dual left anterior descending coronary artery (LAD is defined as the presence of two LADs within the anterior interventricular sulcus (AIVS, and is classified into four types. Type IV is a rarely reported subtype and differs from the others, with a long LAD originating from the right coronary artery (RCA. Dual LAD is a benign coronary artery anomaly, but should be recognised especially before interventional procedures. With the increasing use of multidedector computed tomography (MDCT, it is essential for radiologists to be aware of this entity and the cross-sectional findings.

    Full Text Available Radiologist always examines X-ray to determine abnormal changes in cervical, lumbar & thoracic vertebrae. Osteophyte (bony growth may appear at the corners of vertebrae so that vertebral shape becomes abnormal. This paper presents the idea from Image processing techniques such as customised Hough transform which will be used for segmentation which should be independent of rotation, scale, noise & shape. This segmented image will be then used for computing size invariant, convex hull based features to differentiate normal cervical vertebrae from cervical vertebrae containing anterior osteophyte. This approach effectively finds anterior osteophytes in cervical vertebrae.

    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

    2015-09-01

    Full Text Available Anterior teeth movement in orthodontic treatment is limited to labiolingual direction by very thin alveolar bone. An uncontrolled anterior tooth movement to labiolingual direction can cause alveolar bone perforation at its root segment. This case report is to remind us that alveolar bone thickness limits orthodontc tooth movement. A case of crowded anterior teeth with thin alveolar bone in malocclusion I is reported. This case is treated using adgewise orthodontic appliance. Protraction of anterior teeth is anticipated due to thin alveolar bone on the anterior surface. The conclusion is although the alveolar bone surrounding the crowded anterior teeth is thin, by controlling the movement the teeth reposition is allowed.

    Full Text Available The anterior retropharyngeal approach (ARPA accesses anteriorly situated lesions from the clivus to C3, in patients with a short neck, Klippel Feil anomaly or those in whom the C2-3 and C3-4 disc spaces are situated higher in relation to the hyoid bone and the angle of mandible where it is difficult to approach this region using the conventional anterior approach, due to the superomedial obliquity of the trajectory. The ARPA avoids the potentially contaminated oropharyngeal cavity providing for a simultaneous arthrodesis and instrumentation during the primary surgical procedure. Experience of five patients with high cervical extradural compression, who underwent surgery using this approach between 1994 and 1999, is presented. The surgical procedures included excision of ossified posterior longitudinal ligament (n=2; excision of prolapsed disc and osteophytes (n=2; and excision of a vertebral body neoplasm (n=1. Following the procedure, vertebral arthrodesis was achieved using an iliac graft in all the patients. Only one patient with vertebral body neoplasm required an additional anterior cervical plating procedure for stabilisation the construct. The complications included transient respiratory insufficiency and neurological deterioration in two patients; and, pharyngeal fistula and donor site infection in one patient.

    Full Text Available In order to prevent anterior cruciate ligament injuries it is necessary to define risk factors and to analyze the most frequent causes of injuries - that being the aim of this study. The study sample consisted of 451 surgically treated patients, including 400 sportsmen (65% of them being active and 35% recreational sportsmen, 29% female and 71% male; of whom 90% were younger than 35. Sports injuries, as the most frequent cause of anterior cruciate ligament injuries, were recorded in 88% of patients (non-contact ones in 78% and contact ones in 22%, injuries occurring in everyday activities in 11% and in traffic in 1%. Among sportsmen, reconstruction of the anterior cruciate ligament was most frequently performed in football players (48%, then in handball players (22%, basketball players (13%, volleyball players (8%, martial arts fighters (4%. However, the injury incidence was the highest among the active basketball players (1 injured among 91 active players. Type of footwear, warming up before the activity, genetic predisposition and everyday therapy did not have a significant influence on getting injured. Anterior cruciate ligament injuries happened three times more often during matches, in the middle and at the end of a match and training session (79%, at landing after the jump or when changing direction of movement (75% without a contact with other competitors, on dry surfaces (79%, among not so well prepared sportsmen.

    In the acute setting, accurate radiological interpretation of paediatric cervical spine trauma can be difficult due to a combination of normal variants and presence of multiple synchondroses. We present a rare case of a fracture through the anterior atlantal synchondrosis in a paediatric spine. A five-year-old boy, who fell backwards onto the top of his head while swinging across on a monkey bar frame, presented with neck pain, cervical muscle spasm and decreased right lateral rotation and extension of his neck. Computed tomography showed a displaced diastatic fracture through right anterior atlantal synchondrosis. There are only 12 cases of paediatric C1 fractures reported in the world literature. The importance of considering this diagnosis in the appropriate clinical setting, and the normal variants in the paediatric atlas that can cause diagnostic dilemma to the interpreting radiologist, are discussed in this case report.

    In the context of emotion information processing, several studies have demonstrated the involvement of the amygdala in emotion perception, for unimodal and multimodal stimuli. However, it seems that not only the amygdala, but several regions around it, may also play a major role in multimodal emotional integration. In order to investigate the contribution of these regions to multimodal emotion perception, five patients who had undergone unilateral anterior temporal lobe resection were exposed...

    Impairment-based evaluation has, until recently, been the mainstay of orthopaedic research in anterior cruciate ligament (ACL) reconstruction. However, participation-based outcomes, in particular returning to sport, have lately garnered increased research attention. This is important because returning to sport is typically a main concern of injured athletes. Recent metaanalyses have demonstrated that the return to sport rate after ACL reconstruction is disappointingly low, and that a range of...

    Full Text Available Aim. The aim of this study is to introduce a new technique, anterior vaginal wall darn (AVWD, which has not been used before to repair the anterior vaginal wall prolapse, a common problem among women. Materials and Methods. Forty-five women suffering from anterior vaginal wall prolapse were operated on with a new technique. The anterior vaginal wall was detached by sharp and blunt dissection via an incision beginning from the 1 cm proximal aspect of the external meatus extending to the vaginal apex, and the space between the tissues that attach the lateral walls of the vagina to the arcus tendineus fascia pelvis (ATFP was then darned. Preoperation and early postoperation evaluations of the patients were conducted and summarized. Results. Data were collected six months after operation. Cough stress test (CST, Pelvic Organ Prolapse Quantification (POP-Q evaluation, Incontinence Impact Questionnaire (IIQ-7, and Urogenital Distress Inventory (UDI-6 scores indicated recovery. According to the early postoperation results, all patients were satisfied with the operation. No vaginal mucosal erosion or any other complications were detected. Conclusion. In this initial series, our short-term results suggested that patients with grade II-III anterior vaginal wall prolapsus might be treated successfully with the AVWD method.

    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.

    MRI of a 62-year-old female presenting with ankle pain demonstrated an accessory muscle within the anterior compartment of the lower leg. The muscle originated from the fibula and anterior crural septum. The tendon passed anterior to the lateral malleolus and inserted at the critical angle of Gissane on the calcaneus. This muscle was initially described in the anatomic literature by Lambert and Atsas in 2010. To our knowledge, this is the first time the MRI appearances of this muscle has been described in the radiological literature. Awareness of the fibulocalcaneal muscle is important as it may represent a cause of ankle pain. In addition, the tendon could potentially be harvested for use in reconstructive procedures. (orig.)

    Full Text Available Background: Evaluation of result of anterior cervical approach with manubriotomy and anterior instrumentation in tuberculosis of cervicothoracic spine in terms of the neurological recovery, reconstruction of spine and prevention of deformity along with relief of pain. Materials and Methods: All five patients with cervicothoracic caries spine had surgery through anterior cervical approach with manubriotomy in our hospital and underwent excision of the involved vertebrae and intervertebral discs followed by anterior spinal reconstruction with titanium spacer cage filled with cancellous iliac crest bone graft and Orion plate with locking screw. Antitubercular drugs were administered for 12 months. The follow-up period ranged from 12 to 36 months. Results: Analysis of result was done on the basis of clinical and radiological criteria. Clinical assessment based on Frankel grade and modified JOA score showed significant improvement from preoperative findings. Radiological assessment showed osteointegration, no spinal instability and no progression of the deformity. The pain control, based on visual analog scale changed from a pre-operative average of 7.5 to 2 at the last follow-up thereby indicating significant improvement and all patients returned to preoperative functional status. One patient had transient hoarseness of voice. No other complication had been encountered in the immediate post operative and during the follow-up period. Conclusions: Our study showed that anterior cervical approach with manubriotomy and anterior insertion of titanium cage, filled with autogenous bone graft, secured with locking plate instrumentation has a successful role in the eradication of infection, neurological recovery, segmental spinal reconstruction and it also reduces surgical time, blood loss, and surgical complications and approach related comorbidity in follow up period.

Five of these patients developed TASS postoperatively.Results: Patients had blurred-vision complaints on the first day after the operation, but no pain. They had different degrees of diffuse corneal edema, anterior-chamber reaction, fibrin, hypopyon, iris atrophies, and dilated pupils. Their vision decreased significantly, and their intraocular pressures increased. Both anti-inflammatory and antiglaucomatous therapies were commenced. Corneal edema and inflammation resolved in three cases; however, penetrating keratoplasty was needed for two cases and additional trabeculectomy was needed for one case. Although full investigations were undertaken at all steps, we could not find the causative agent.Conclusion: TASS is a preventable complication of anterior-segment surgery. Recognition of TASS, differentiating it from endophthalmitis, and starting treatment immediately is important. Controlling all steps in surgery, cleaning and sterilization of the instruments, and training nurses and other operation teams will help us in the prevention of TASS.

    Full Text Available Introduction. Infections after anterior cruciate ligament reconstructions are rare, but, on the other hand, they are difficult to be treated. The aim of this study was to analyze causes of infections, risk factors, diagnostics, and possibilities of their prevention. Material and Methods. Seventeen deep infections (1.2% were found in 1425 patients who had undergone anterior cruciate ligament reconstructions. Fifteen patients were males and two were females. Out of 475 professional athletes nine (1.9% had this postoperative complication. Eleven patients with septic arthritis were allergic to penicillin. Three of them had immunosuppressive diseases. Results. Staphylococcus aureus was isolated in eleven cases (65%, other Staphylococcus and Streptococcus groups were found in four and three patients, respectively; while one patient had infection although the punctate was negative. Out of 965 patients with the patellar tendon grafts, ten (1.03% had this complication, while the incidence was 1.52% (7/460 in those with the hamstring grafts. Fifteen infections were acute with obvious symptoms within 14 days after surgery. Severe pain, limited range of motion, swelling of the knee joint and fever were the most common symptoms, while rubor and pus developed rarely. The infection was three times more frequent in the patients who had undergone surgery lasting more than 1.5 hour. Discussion and Conclusion. The following population groups are at risk of developing septic arthritis after anterior cruciate ligament reconstructions: professional athletes, those who are allergic to penicillin, and those with immunosuppressive diseases. Staphyllococus aureus is the most common cause of infection. The patients with the hamstring autografts have a higher risk than those with the patellar tendon grafts. Preventive measures that should be performed include aseptic conditions in operative rooms, irrigation of the graft before its placement into the bone tunnels

    Full Text Available The neural network that contributes to the suffering which accompanies persistent pain states involves a number of brain regions. Of primary interest is the contribution of the cingulate cortex in processing the affective component of pain. The purpose of this review is to summarize recent data obtained using novel behavioral paradigms in animals based on measuring escape and/or avoidance of a noxious stimulus. These paradigms have successfully been used to study the nature of the neuroanatomical and neurochemical contributions of the anterior cingulate cortex to higher order pain processing in rodents.

    Full Text Available Successful anterior cruciate ligament (ACL reconstruction with tendon graft requires extensive tendon-to-bone healing in the bone tunnels and progressive graft ligamentization for biological, structural, and functional recovery of the ACL. Improvement in graft-to-bone healing is crucial for facilitating early, aggressive rehabilitation after surgery to ensure an early return to pre-injury activity levels. The use of various biomaterials for enhancing the healing of tendon grafts in bone tunnels has been developed. With the biological enhancement of tendon-to-bone healing, biological fixation of the tendon graft in the tunnel can be achieved in ACL reconstruction.

    The purpose of the study was to describe the findings seen on anterior segment spectral domain optical coherence tomography (SD-OCT) in patients with anterior scleritis and determine the feasibility of using SD-OCT to image and grade the degree of scleral inflammation and monitor response to treatment. All patients underwent slit lamp examination by a uveitis specialist, and the degree of scleral inflammation was recorded. Spectral domain OCT imaging was then performed of the conjunctiva and scleral tissue using a standardized acquisition protocol. The scans were graded and compared to clinical findings. Twenty-eight patients with anterior scleritis and ten patients without ocular disease were included in the study. Seventeen of the scleritis patients were followed longitudinally. Common findings on SD-OCT in patients with active scleritis included changes in hyporeflectivity within the sclera, nodules, and visible vessels within the sclera. There was significant variation in findings on SD-OCT within each clinical grade of active scleritis. These changes on SD-OCT improved with treatment and clinical improvement. SD-OCT imaging provided various objective measures that could be used in the future to grade inflammatory activity in patients with anterior scleritis. Longitudinal imaging of patients with active scleritis demonstrated that SD-OCT may have great utility in monitoring response to treatment.

    2016-06-01

    Anterior cervical fusion has become a standard of care for numerous pathologic conditions of the cervical spine. However, subsequent development of clinically significant disc disease at levels adjacent to fused discs is a serious long-term complication of this procedure. As more patients live longer after surgery, it is foreseeable that adjacent segment pathology (ASP) will develop in increasing numbers of patients. Also, ASP has been studied more intensively with the recent popularity of motion preservation technologies like total disc arthroplasty. The true nature and scope of ASP remains poorly understood. The etiology of ASP is most likely multifactorial. Various factors including altered biomechanical stresses, surgical disruption of soft tissue and the natural history of cervical disc disease contribute to the development of ASP. General factors associated with disc degeneration including gender, age, smoking and sports may play a role in the development of ASP. Postoperative sagittal alignment and type of surgery are also considered potential causes of ASP. Therefore, a spine surgeon must be particularly careful to avoid unnecessary disruption of the musculoligamentous structures, reduced risk of direct injury to the disc during dissection and maintain a safe margin between the plate edge and adjacent vertebrae during anterior cervical fusion.

    The purpose of this study was to assess the usefulness of MRI in the evaluation of autografts after anterior cruciate ligament reconstruction. The subjects were 110 patients with anterior cruciate ligament reconstruction using patellar tendon autografts who underwent clinical examination, MRI, and arthroscopy of the knee. T1- and T2-weighted MR images were obtained in sagittal plane. Clinical findings were categorized into three groups: normal, borderline, and abnormal. The MRI appearances of the autografts were categorized into three types: straight continuous band (type I), interrupted band (type II) and generalized increased intensity band (type III). The clinical findings and MRI findings were compared with arthroscopic findings. Ninety-six percent of the type I showed no autograft tear on arthroscopy. In comparison with the clinical findings, MRI was found to be well correlated with arthroscopic findings. In conclusion, if the clinical findings are normal, patients are to be followed-up without MRI and arthroscopy. However, if clinical findings are either borderline or abnormal, MRI should be performed prior to arthroscopy. (author)

    Anterior fixation devices for the thoracolumbar spine have gained wide acceptance as viable alternatives to long-segment posterior fixation in cases of thoracolumbar spine trauma. This review was undertaken to evaluate the safety and efficacy of the Synthes anterior thoracolumbar locking plate (ATLP) system. Over a 3-year period, 31 patients with unstable traumatic fractures of the thoracolumbar spine underwent corpectomy, placement of a structural bone graft, and anterior fixation in which the Synthes ATLP system was used. Long-term follow-up data were obtained in 29 patients. Two patients were lost to follow up, one at 4 months and the other at 1 year. In the remaining patients, the average length of follow up was 20 months. In all patients radiographic evidence of solid bone fusion was demonstrated on follow-up plain x-ray films, and there were no signs or symptoms of pseudarthrosis. No patient suffered neurological deterioration as a result of surgery, and there was relatively little morbidity associated with this plating system. To date, none of the patients in this study has developed any delayed complications related to the fixation device. In one patient, who had sustained a severe flexion injury, loosening of the anterior fixation device occurred, and the patient developed progressive kyphosis, which required a posterior stabilization procedure. These results appear slightly better than those obtained in published studies in which other anterior plating systems were used, indicating that this system is safe and effective in the treatment of unstable fractures of the thoracolumbar spine.

    Functional imaging studies of psychopathy have demonstrated reduced activity in the anterior cingulate, yet it is unclear whether this region is structurally impaired. In this study, we used structural MRI to examine whether volumetric differences exist in the anterior cingulate between psychopathic (n=24) and control (n=24) male participants. We found no group differences in the volume of the anterior cingulate or its dorsal and ventral subregions. Our findings call into question whether the...

    2014-11-01

    Video-assisted thoracoscopic surgery (VATS) has been widely used, but surgical resections of superior sulcus tumours remain challenging because of their anatomical location. For such cases, less-invasive procedures, such as the anterior transcervical-thoracic and transmanubrial approaches, have been widely performed because of their excellent visualization of the subclavian vessels. Recently, a combined operative technique with an anterior surgical approach and VATS for anterior superior sulcus tumours has been introduced. Herein, we report three cases of anterior superior sulcus tumours successfully resected by surgical approaches combined with a VATS-based lobectomy. In all cases, operability was confirmed by VATS, and upper lobectomies with hilar and mediastinal lymph node dissections were performed. Subsequently, dissections of the anterior inlet of the tumours were performed using the transmanubrial approach in two patients and the anterior trans-cervical-thoracic approach in one patient. Both approaches provided excellent access to the anterior inlet of the tumour and exposure of the subclavian vessels, resulting in radical resection of the tumour with concomitant resection of the surrounding anatomical structures, including the chest wall and vessels. In conclusion, VATS lobectomy combined with the anterior surgical approach might be an excellent procedure for the resection of anterior superior sulcus tumours.

    The lack of reported complications related to lower extremity peripheral nerve blocks (PNBs) may be related to the relatively infrequent application of these techniques and to the fact that most such events go unpublished. Our current understanding of the factors that lead to neurologic complications after PNBs is limited. This is partly the result of our inability to conduct meaningful retrospective studies because of a lack of standard and objective monitoring and documentation procedures for PNBs. We report a case of permanent injury to the sciatic nerve after sciatic nerve block through the anterior approach and discuss mechanisms that may have led to the injury. Intraneural injection and nerve injury can occur in the absence of pain on injection and it may be heralded by high injection pressure (resistance).

    Objectives: The aim of this study was to evaluate the mid-term radiological and clinical outcomes of tibial tubercle osteotomy in patients affected by anterior knee pain. In addition, prognostic factors correlated with the outcomes were evaluated. Methods: The patients treated with tibial tubercle osteotomy (anteromedialization) for anterior knee pain between 2002 and 2014 were included. Exclusion criteria: 1) previous knee surgeries; 2) different procedures to treat anterior knee pain; 3) history of patellar dislocation, 4) Rheumatic conditions. Different variables were collected, as shown in. The patients were prospectively evaluated using the WOMAC short form and Kujala scores. An objective evaluation was performed looking for different potential risk factors and using part of the International Knee Documentation Committee (IKDC) score. Radiological evaluation was performed, including the congruence angle, the grade of osteoarthritis (Kellegren-Lawrence) and the patellar tilt angle. Three main outcomes were identified. The multiple logistic regression was used to analyze the correlation between the variables and a worse outcome. Results: 72 cases were included in the study (9 bilateral). 72.2% of the cases were female, and the average age was 42,2 years (SD15,9). The average BMI was 24.4 kg/m2 (SD5,2). In 70.8% of patients a lateral release was associated to the tibial tubercle osteotomy. 77.8% of patients were evaluated clinically, the remaining, who were unable to come for the visits, were interviewed and the subjective scores were administered by phone. The average follow-up was 68.4 months (SD35.5).In 62.5% of cases a valgus lower limb alignment was detected, with 25% and 39.3% of patients having respectively an increased femoral antiversion and foot pronation. Post-operatively there was a statistical significant improvement in all the scores. No differences in the pre-operative and post-operative congruence angle or patellar tilt were detected (p>0.05).

    2015-04-01

    Full Text Available ABSTRACT We read with interest the article by Surekha et al. regarding the retained stone piece in anterior chamber. Similar to the results of previous studies, the authors found that delayed intraocular foreign body (IOFB management can result in good visual outcome without an apparent increased risk of endophthalmitis or other deleterious side effects. However, the authors failed to explain the exact reason for the diminution of vision in patients left eye. It is unclear what the uncorrected visual acuity was and what kind of correction was used, more precisely type and amount of cylinder, given the presence of the corneal opacity. Since the size of the IOFB is approximately 4x4x1mm, significant irido-corneal angle changes resulting in intraocular pressure raise and optic nerve head damage can be expected. Traumatic glaucoma following open globe injury can occur in 2.7 to 19% of cases, with several risk factors associated with glaucoma development (advanced age, poor visual acuity at presentation,perforating rather than penetrating ocular injury,lens injury, presence of vitreous hemorrhage and presence of an IOFB. Earlier reportsof latetraumaticoptic neuropathy onset, even after several years, indicate that this possibility cannot be completely ruled out too. Therefore, repeated intraocular pressure measurements, gonioscopy, pupillary reaction assessment, together with through posterior segment examination including visual field and optical coherence tomography examinations can be useful in determining the possible optic nerve damage as one of the possible reasons for visual acuity reduction. The authors did not suggest any operative treatment at this time. However, it should bear in mind that the inert anterior chamber IOFB could be a risk factor for non-infectious endophthalmitis development even after many years. Also, long term retained anterior chamber foreign body leads to permanent endothelial cell loss and can even result in a corneal

    To investigate magnetic resonance (MR) imaging of anterior cruciate ligament (ACL) tears, the authors retrospectively reviewed 39 MR imaging examinations in 39 patients. We classified the MR imaging patterns of the torn ACL into four types. Torn ACL appears as a homogeneous iso-intensity mass on Type I images; as a continuous thin and waving low-intensity band with or without high-signal-intensity spots on the Type II images; as a disrupted band with a high-signal-intensity area on Type III images and as an absence of the ACL on Type IV images. We also report secondary lesions on MR imaging findings associated with tears of the ACL, posterior cruciate ligament index and bone bruising, in our patients. (author).

  1. MR imaging evaluation of anterior cruciate ligaments

    International Nuclear Information System (INIS)

    On 546 knees, the authors have obtained MR images (0.5 T or 1.5 T). The protocol included 5-mm-thick contiguous sagittal and oblique coronal images (in the plane of the anterior cruciate ligament [ACL]) and T1-, proton-density-, and T2-weighted sequences. In 174 patients, correlations with arthroscopic or surgical findings were available. In these cases, sagittal and oblique coronal images were retrospectively and separately read by two radiologists, who were blinded to other results. The mean accuracy of sagittal MR images alone was 88% for the depiction of partial and complete ACL tears, intraligamental bleeding, and scarring; the accuracy of oblique coronal images alone was 96%. Use of sagittal and oblique coronal images together achieved 98% accuracy

    Bone contusions are an important ancillary finding of many knee injuries. Not only are they a source of pain, they may suggest a mechanism of injury or a specific derangement of the knee joint. We have encountered a small number of patients being evaluated for anterior cruciate ligament (ACL) tears with unexplained patellar and tibial edema at magnetic resonance (MR) imaging. We present three individuals with contusions of the inferior patella with a corresponding contusion of the anteromedial tibial plateau. Internal derangements in these patients were similar to other individuals with acute ACL tears, however osseous contusions were more widespread. In conclusion, patellotibial contusions are rare and may indicate an injury with forces greater than usually encountered in most ACL tears. A careful search for uncommon associated injuries is prudent in these high-energy knee injuries. PMID:24037484

  3. Concrescent triplets involving primary anterior teeth

    2013-01-01

    Full Text Available Odontogenesis is a complex process wherein more than 200 genes are known to play a significant role in tooth development. An imbalance can lead to an abnormality in the number, size, shape or structure of the developing tooth/teeth. The presence of an extra dental lamina forms a supernumerary tooth. The supernumerary teeth are of two types: A rudimentary tooth where the supernumerary tooth does not resemble any tooth in the normal series or a supplemental tooth in which this anomalous tooth resembles one in the normal series. It is also very rare to encounter triple teeth in primary dentition. The union of these teeth may be through fusion, gemination, concrescence or a combination of fusion and gemination. Presented is a rare case of concrescence involving maxillary deciduous incisors and a supplemental tooth in a 7-year-old boy. The differential diagnosis, etiology, and complications of primary anterior triple teeth are discussed.

    2010-03-01

    The relatively high risk of noncontact anterior cruciate ligament (ACL) rupture among female athletes has been a major impetus for investigation into the etiology of this injury. A number of risk factors have been identified, both internal and external to the athlete, including neuromuscular, anatomical, hormonal, shoe-surface interaction, and environmental, such as weather. The anatomic and neuromuscular risk factors, often gender related, are the focus of most ACL injury prevention programs. Although studies have shown that biomechanic- centered prevention programs can reduce the risk of ACL injury, many questions remain unanswered. More research is needed to increase our understanding of the risk factors for ACL injury; how injury prevention programs work and can the clinical application of such programs be optimized.

    Full Text Available Background: Although microscopic anterior cervical discectomy with or without fusion are common surgical procedures for treatment of cervical herniated discs, loss of disc height, pseudarthrosis, and adjacent disc degeneration are some of the problems associated with it. This study is aimed to evaluate results of endoscopic microforaminotomy in cervical disc diseases. Materials and Methods: A prospective study of 50 patients of mono segmental soft or hard disc causing myeloradiculopathy was undertaken. A visual analogue scale (VAS for neck and arm pain and functional outcomes using the Nurick grading system were assessed. There were 28, 12, 8, and 2 patients at C5-6, C6-7, C4-5, and C3-4 levels disc diseases, respectively. Patients with two or more level disc, instabilities, disc extending more than half vertebral body height, and previous operation at the same segment were excluded. Results: Age ranged from 21 to 67 years. Average postoperative reduction in disc height, operating time, and blood loss was 1.1 mm, 110 minutes, and 30 ml, respectively. Average pre-operative VAS score for arm pain and Nurick grading was 7.6 and 2.7, which improved to 1.9 and 0.82, respectively. All patients improved; 1, 2, 3 grade improvement was seen in 10, 27, and 10 patients, respectively. There was no significant complication or any mortality. Conclusion: Although longer follow up of large number of patients is required, endoscopic microforaminotomy is a safe and an effective alternative to microscopic anterior discectomy with or without fusion.

  6. Etiological aspects of anterior open bite

    Directory of Open Access Journals (Sweden)

    Stojanović Ljiljana

    2007-01-01

    Full Text Available Introduction. Open bite is a multifactorial phenomenon and no single factor can account for open-bite. Etiology plays an important role in diagnosis. Heredity, unfavorable growth patterns, incorrect jaw postoure, are the characteristics of skeletal open bite. Digit sucking. Depending on where the thumb is placed, a number of different types of dental problems can develop. Malocclusions of the late mixed or permanent dentitions, caused by thumb sucking are not self corrected and orthodontic treatment is necessary for their correction. Lymphatic tissue. In order to produce oral respiration, the mandible is postured inferiorly with the tongue protruded and resting against the oral floor. This postural alteration induces dental and skeletal modifications similar to those caused by thumb sucking. This may cause excessive eruption of the posterior teeth, leading to an increase in the vertical dimension of the face and result in development of anterior open bite. Tongue thrust. Tongue habits cause an anterior open bite or they develop secondarily to thumb sucking. In skeletal open bite the tongue habit acts as a secondary factor which helps to maintain or exacerbate the condition. Many orthodontists have had a discouraging experience of completing dental treatment, with what appeared to be good results, only to discover that the case had relapsed because the patient had a tongue thrust swallowing pattern. Conclusion. Dentoalveolar or habitual open bite is caused by habits, which influence the growth and development of dentoalveolar processes and contribute to occlusal disharmonies. Prior to eruption of adult dentition, open bite related to oral habits is usually not a concern as when the habits stop, because the erupting dentition tends to improve spontaneously. Treatment is usually not necessary until permanent teeth erupt (~6 years old. .

All patients underwent prior soft tissue stabilization; those with prior open bone grafting procedures were excluded. For patients with 25% glenoid bone loss, Latarjet was performed (n=28). Patients were queried regarding recurrent instability (subluxation or dislocation). Clinical outcomes were evaluated using validated patient reported outcome questionnaires including the American Shoulder and Elbow Surgeons (ASES) score, Simple Shoulder Test (SST), visual analog scale (VAS) for pain, and Western Ontario Shoulder Instability Index (WOSI). Results: A total of 63 shoulders in 62 patients (46 males, 16 females) with an average age of 23.2 ± 6.9 years were included in the revision arthroscopy group. At an average follow-up of 46.9 ± 16.8 months (range, 15 to 78), the mean WOSI score was 80.1 (range, 15.0 to 100), and there were significant improvements (pLatarjet group. Thirteen (46%) had more than one previous stabilization attempt. ), the average WOSI score was 71.9, and there were significant improvements (pLatarjet. Conclusion: Both arthroscopic revision stabilization and Latarjet coracoid transfer result in satisfactory outcomes in patients who have failed previous arthroscopic capsulolabral repair. Recurrent instability rates were higher in the all-arthroscopic group (19% versus 7%). Longer-term studies are required to determine whether similar results are maintained over time, and to provide guidance on focused clinical indications for this challenging patient population.

    Anterior cruciate ligament (ACL) injury in the skeletally immature individual is being recognized with increasing frequency. Nonoperative treatment of ACL injuries in skeletally immature patients have not been favorable. Surgical treatment options for complete ACL tears include primary ligament repair, extraarticular tenodesis, transphyseal reconstruction, partial transphyseal reconstruction, and physeal-sparing reconstruction. The advantage of transphyseal reconstruction is placement of the graft tissue in an isometric position, which provides better results, according to the literature. The potential disadvantage is angular or limb-length discrepancy caused by physeal violation. Controversy exists in allograft selection about whether bone or soft tissue passes into physes. The use of standard tunnels provides reliable results, but carries the risk of iatrogenic growth disturbance from physeal injury.This article presents 4 cases of transphyseal ACL reconstruction using anterior tibialis allograft in skeletally immature patients that had satisfactory functional outcomes with no growth disturbances. This is the first report of transphyseal ACL reconstruction using anterior tibialis allograft in skeletally immature patients in the English-speaking literature. All patients underwent transphyseal ACL reconstruction using anterior tibialis tendon allograft. None of the patients had angular deformities. No early physeal arrest was measured between the preoperative and postoperative radiographs. At last follow-up, the results of the Lachman test were normal for 3 patients and nearly normal for 1 patient. All patients demonstrated full range of knee motion (comparing the reconstructed knee to the contralateral knee). The results of the pivot-shift test were normal for 3 patients and nearly normal for 1 patient. No patients reported giving way.

    1998-10-01

    A 51-year-old woman presented with a distal anterior cerebral artery aneurysm (DACAA) manifesting as severe headache and monoparesis of the left lower limb. Computed tomography revealed subarachnoid hemorrhage in the interhemispheric fissure, bilateral sylvian fissures, and basal cistern, and a hematoma in the supracallosal region. Angiography showed a large aneurysm (23 x 18 mm) located on the distal end of the azygos anterior cerebral artery (azygos ACA) at the supracallosal portion. T2-weighted magnetic resonance imaging demonstrated the hematoma as a mixed intensity mass, compressing the corpus callosum downward, and the aneurysm as a flow void anterior to the hematoma. Unilateral frontoparietal parasagittal craniotomy was performed with a horse-shoe shaped incision. The aneurysm was clipped via the interhemispheric approach, and the hematoma was aspirated. Postoperative angiography showed disappearance of the aneurysm and intact azygos ACA. The patient was discharged with mild monoparesis, paresthesia of the left lower limb and diagnostic dyspraxia. DACAA almost always arises at or near the genu of the corpus callosum and is often associated with vascular anomaly. In the literature, 22 of 26 cases of large and giant DACAA were located at or near the genu, but only 3 cases, including ours, in the supracallosal area. 11 cases were associated with azygos ACA. Therefore, hemodynamic stress caused by vascular anomaly may be involved in the formation of large or giant DACAA in contrast with cases of normal DACAA. PMID:9789300

    Zebrafish with defective Nodal signaling have a phenotype analogous to the fatal human birth defect anencephaly, which is caused by an open anterior neural tube. Previous work in our laboratory found that anterior open neural tube phenotypes in Nodal signaling mutants were caused by lack of mesendodermal/mesodermal tissues. Defects in these mutants are already apparent at neural plate stage, before the neuroepithelium starts to fold into a tube. Consistent with this, we found that the requirement for Nodal signaling maps to mid-late blastula stages. This timing correlates with the timing of prechordal plate mesendoderm and anterior mesoderm induction, suggesting these tissues act to promote neurulation. To further identify tissues important for neurulation, we took advantage of the variable phenotypes in Nodal signaling-deficient sqt mutant and Lefty1-overexpressing embryos. Statistical analysis indicated a strong, positive correlation between a closed neural tube and presence of several mesendoderm/mesoderm-derived tissues (hatching glands, cephalic paraxial mesoderm, notochord, and head muscles). However, the neural tube was closed in a subset of embryos that lacked any one of these tissues. This suggests that several types of Nodal-induced mesendodermal/mesodermal precursors are competent to promote neurulation.

    The purpose of this study was to analyse the occurrence of variants of anomalous insertions of the anterior horn of the medial meniscus in human knee joints. The study was carried out on 78 human lower limbs of both sexes (42 males and 36 females). Out of 78 knee joints, 10 knee joints (12.82%) presented atypical attachments of the anterior horn of the medial meniscus. In 9 cases we found that the anterior horn of the medial meniscus was attached to the transverse ligament of the knee and in 1 case it was attached to the coronary ligament. In the remaining cases the anterior horn of the medial meniscus was attached to the anterior intercondylar area of the tibia.

    Anterior chamber volume (ACV) is very important for an oculist to make rational pathological diagnosis as to patients who have some optic diseases such as glaucoma and etc., yet it is always difficult to be measured accurately. In this paper, a method is devised to measure anterior chamber volumes based on JPEG-formatted image files that have been transformed from medical images using the anterior-chamber optical coherence tomographer (AC-OCT) and corresponding image-processing software. The corresponding algorithms for image analysis and ACV calculation are implemented in VC++ and a series of anterior chamber images of typical patients are analyzed, while anterior chamber volumes are calculated and are verified that they are in accord with clinical observation. It shows that the measurement method is effective and feasible and it has potential to improve accuracy of ACV calculation. Meanwhile, some measures should be taken to simplify the handcraft preprocess working as to images.

  3. Anterior commissure versus corpus callosum: A quantitative comparison across mammals.

    2016-04-01

    Mammals rely on two major pathways to transfer information between the two hemispheres of the brain: the anterior commissure and the corpus callosum. Metatheria and monotremes rely exclusively on the anterior commissure for interhemispheric transfer between the isocortices and olfactory allocortices of each side, whereas Eutheria use a combination of the anterior commissure and an additional pathway exclusive to Eutheria, the corpus callosum. Midline cross-sectional area of the anterior commissure and corpus callosum were measured in a range of mammals from all three infraclasses and plotted against brain volume to determine how midline anterior commissure area and its size relative to the corpus callosum vary with brain size and taxon. In Metatheria, the square root of anterior commissure area rises in almost direct proportion with the cube root of brain volume (i.e. the ratio of the two is relatively constant), whereas among Eutheria the ratio of the square root of anterior commissure area to the cube root of brain volume declines slightly with increasing brain size. The total of isocortical and olfactory allocortical commissure area rises more rapidly with increasing brain volume among Eutheria than among Metatheria. This means that the midline isocortical and olfactory allocortical commissural area of metatherians with large brains (about 70 ml) is only about 50% of that among eutherians with similarly sized brains. On the other hand, isocortical and olfactory allocortical commissural area is similar in Metatheria and Eutheria at brain volumes around 1 ml. Among the Eutheria, some groups make less use of the anterior commissure pathway than do others: soricomorphs, rodents and cetaceans have smaller anterior commissures for their brain size than do afrosoricids, erinaceomorphs and proboscideans. The findings suggest that use of the anterior commissural route for isocortical commissural connections may have placed limitations on interhemispheric transfer of

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 to 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 1848, 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

    Full Text Available Cataratas polares anteriores piramidais são opacidades cônicas que se projetam para a câmara anterior a partir da cápsula anterior do cristalino. Na grande maioria dos pacientes a opacidade permanece aderida e estável durante toda a vida. O objetivo deste trabalho é documentar uma manifestação incomum desse tipo de catarata: a deiscência espontânea das pirâmides para a câmara anterior causando descompensação endotelial e edema corneal bilateral. Relatamos o caso de uma paciente feminina, de 66 anos, branca, que apresentava edema corneal localizado inferiormente no olho direito associado à lesão nodular branco-esclerótica compatível com a pirâmide anterior da catarata polar. O olho esquerdo apresentava edema corneal difuso intenso e presença de uma catarata polar anterior com a região piramidal deslocada para a câmara anterior. Sabe-se que a pirâmide anterior pode permanecer inabsorvida na câmara anterior por longo período, pois é composta de tecido colágeno denso. Isto causa perda endotelial progressiva e edema corneal e deve ser considerada indicação de remoção cirúrgica da catarata polar anterior e de seu fragmento. Ressalta-se, também, a importância do bom senso no julgamento das cataratas polares anteriores, considerando-se tamanho da opacidade, simetria das opacidades e componente cortical associado, na tentativa de se evitar ambliopia.Pyramidal anterior polar cataracts are conical opacities that project into the anterior chamber from the anterior capsule of the lens.

There were 84 males and 69 females with an average age of 47.9±13.7 years (range,14 to 82 years).Everyone's whole spine plain radiograph were reviewed to verify whether sacralized vertebra were ignored. Result:7 cases with non-squaring sacralized vertebra were missed as normal lumbosacral structure under lumbar plain radiographs alone. Among them, there were 5 males and 2 female with an average age of 39.7±13.7 years(range,21 to 60 years).All sacralized vertebra exhibited normal S1 vertebra shape with its lower disc exhibiting normal fused S1/2 intervertebral disc appearance.2 were complicated with cervical ribs of the 7th cervical vertebra while 4 had the 12th ribs absence. These pitfalls could only be identified and corrected under whole spine radiograph. Conclusion: Non-squaring sacralized vertebra may be missed as normal lumbosacral structure under lumbar plain radiographs alone. Whole spine plain radiograph is recommended.

    2015-01-01

    The purpose of this paper was to review the current literature associated with the techniques and materials for the restoration of primary anterior teeth and make clinical recommendations based upon the available literature. A variety of esthetic restorative materials are available to utilize for restoring primary incisors. Awareness of the specific strengths, weakness, and properties of each material can enhance the clinician's ability to make the best choice of selection for each individual situation. Intracoronal restorations of primary teeth may utilize resin composites, glass ionomer cements, resin-modified ionomers, or polyacid-modified resins. Full coronal restoration of primary incisors may be indicated for a number of reasons. Crowns available for restoration of primary incisors include those that are directly bonded onto the tooth, which generally are a resin material, and crowns that are luted onto the tooth and are either some type of stainless steel or zirconia crown. There is insufficient controlled, clinical data to suggest that one type of restoration is superior to another. Operator preferences, esthetic demands by parents, the child's behavior, the amount of tooth structure remaining, and moisture and hemorrhage control are all variables that affect the decision and ultimate outcome of whatever restorative solution is chosen.

    The purpose of this study was to evaluate using MRI the natural healing of the anterior cruciate ligament (ACL) when treated conservatively by early protective motion. Consecutive acute complete intraligamentous ruptures of the ACL in 50 cases that were allowed to heal without surgery were evaluated before and after 3 month treatment by MRI, arthroscopy, and stress radiographs. Twenty-nine of the 50 patients were also reevaluated 11 months from the initial injury, of which 7 were reevaluated again 24 months from the initial injury by MRI. The MR appearance of the treated ACL was categorized into four grades depending on homogeneity, straight band, and size. MR assessment of the ACL after 3 month treatment demonstrated a well defined normal-sized straight band in 37 cases (74%). There was a significant relationship between the 3 and 11 month MR evaluations (r. = 0.801, p < 0.0001). There were also significant relationships between the MR and arthroscopic evaluations (r, = 0.455, p < 0.005) and between the MR and stress radiographic evaluations (r, = 0.348, p < 0.025) after the 3 month treatment. MRI can demonstrate ACL healing when treated conservatively with early protective mobilization. 40 refs., 3 figs., 2 tabs.

  14. Principles of postoperative anterior cruciate ligament rehabilitation.

    It is known that anterior cruciate ligament (ACL) reconstruction needs to be combined with detailed postoperative rehabilitation in order for patients to return to their pre-injury activity levels, and that the rehabilitation process is as important as the reconstruction surgery. Literature studies focus on how early in the postoperative ACL rehabilitation period rehabilitation modalities can be initiated. Despite the sheer number of studies on this topic, postoperative ACL rehabilitation protocols have not been standardized yet. Could common, "ossified" knowledge or modalities really prove themselves in the literature? Could questions such as "is postoperative brace use really necessary?", "what are the benefits of early restoration of the range of motion (ROM)?", "to what extent is neuromuscular electrical stimulation (NMES) effective in the protection from muscular atrophy?", "how early can proprioception training and open chain exercises begin?", "should strengthening training start in the immediate postoperative period?" be answered for sure? My aim is to review postoperative brace use, early ROM restoration, NMES, proprioception, open/closed chain exercises and early strengthening, which are common modalities in the very comprehensive theme of postoperative ACL rehabilitation, on the basis of several studies (Level of Evidence 1 and 2) and to present the commonly accepted ways they are presently used. Moreover, I have presented the objectives of postoperative ACL rehabilitation in tables and recent miscellaneous studies in the last chapter of the paper. PMID:25232521

  15. Deep anterior lamellar keratoplasty in keratoconus

    Full Text Available Introduction. Deep anterior lamellar keratoplasty (DALK is intended for the surgical treatment of corneal pathology without the involvement of the endothelium. Sparing of the healthy host endothelium for lifetime is of utmost importance in young patients. Therefore, keratoconus is among the main indications for DALK. Outline of Cases. Two men, 22 and 28 years of age, underwent DALK for the treatment of progressive keratoconus, with low visual acuity, impossible to be corrected with gas-permeable contact lenses, due to the extreme conical protrusion of the cornea. Baring of Descemet’s membrane was achieved with lamellar dissection and peeling off the stroma. An 8.5 mm graft without the endothelium was sutured into an 8.0 mm bed. Both grafts remained clear and attached, without either ocular surface pathology or problems arising from sutures. The best corrected visual acuity was 20/25 and 20/40, with the astigmatism of 2.5 and 3.0 diopters, respectively. The follow-up was one year. Conclusion. This is the first presentation of DALK in our literature. The restoration of corneal transparency and stability, with sparing of the host endothelium, has put DALK among successful corneal tranplantation procedures. Together with Descemet stripping endothelial keratoplasty, which already accounts for almost a half of all our keratoplasties, it offers an alternative to penetrating keratoplasty.

    2006-12-01

    Rehabilitation is an important part of therapy in patients who have had arthroscopic anterior cruciate ligament reconstruction. A well-designed rehabilitation program avoids potential graft damage and speeds up patients' return to their full function level. The course of rehabilitation depends on the type of surgery, mode of fixation and possible co-existing injury to the knee's soft tissues. The rehabilitation program presented here is based on the present-day knowledge of neurophysiological and biomechanical principles and is divided into five phases. In the pre-operative phase (I), the main objective is to prepare patients for surgery in terms of maximum muscle strength and range of motion. It also includes providing full information on the procedure. In the early post-operative phase (II) we are concerned with pain alleviation and reduction of knee edema. After suture removal we begin with soft techniques for the patella and post-operative physical therapy to reduce scarring. In the next post-operative phase (III) patients are able to walk with their full weight on the extremity operated on, and we continue doing exercises that improve flexor/extensor co-contraction. In this phase we also begin with exercises improving the patient's proprioceptive and sensorimotor functions. In the late post-operative phase (IV) we go on with exercises promoting proprioception of both lower extremities with the aim of increasing muscle control of the knee joints. In the convalescent phase (V) patients gradually return to their sports activities.

  17. Anterior dental microwear texture analysis of the Krapina Neandertals

    Some Neandertal anterior teeth show unusual and excessive gross wear, commonly explained by non-dietary anterior tooth use, or using the anterior dentition as a tool, clamp, or third hand. This alternate use is inferred from aboriginal arctic populations, who used their front teeth in this manner. Here we examine anterior dental microwear textures of the Krapina Neandertals to test this hypothesis and further analyze tooth use in these hominins. Microwear textures from 17 Krapina Dental People were collected by white-light confocal profilometry using a 100x objective lens. Four adjacent scans were generated, totaling an area of 204x276 μm, and were analyzed using Toothfrax and SFrax SSFA software packages. The Neandertals were compared to six bioarchaeological/ethnographic samples with reported variation in diet, abrasive load, and non-dietary anterior tooth use. Results indicate that Krapina anterior teeth lack extreme microwear textures expected of hominins exposed to heavy abrasives or those that regularly generated high stresses associated with intense use of the front teeth as tools. Krapina hominins have microwear attributes in common with Coast Tsimshian, Aleut, and Puye Pueblo samples. Collectively, this suggests that the Krapina Neandertals faced moderate abrasive loads and only periodically used their anterior teeth as tools for non-diet related behaviors.

    To evaluate main numerical parameters of anterior segment and the effects of eyelid skin changes on these parameters in patients with systemic sclerosis (SSc). Thirty-four patients with SSc and 34 healthy individuals were enrolled. Besides full eye examination, anterior segment measurements including anterior chamber depth (ACD), anterior chamber volume, anterior chamber angle width, central corneal thickness, pupil size, corneal volume and keratometry were obtained using a Sirius Scheimpflug/Placido photography-based topography system. Eyelid thickness was evaluated using the scala of the modified Rodnan skin score and the patients were subgrouped with respect to these scores to evaluate the effect of eyelid thickening on the anterior segment parameters. Age and sex distributions of the groups were similar (p > 0.05). SSc patients had steeper and thinner corneas, smaller corneal volumes, narrower, shallower and smaller anterior segments but only the mean ACD value of right eyes was found significantly less than those of the controls (p = 0.047). The mean ACD values of SSc subgroup patients with moderate to severe eyelid thickening (50 %) had lower ACD measurements compared to those of control group. (p = 0.043 for the right eyes, p = 0.070 for the left eyes). However, SSc subgroup patients with none to mild eyelid thickening (50 %) had similar anterior segment parameters with control subjects (p > 0.05). Anterior chamber parameters of the SSc patients could show significant differences. These differences occur parallel to the eyelid changes but not secondary to it. PMID:26694912

    Background Measurement of anterior segment parameters plays an important role in diagnosis and treatment of glaucoma. The objective of this study was to evaluate the repeatability and reproducibility of anterior chamber volume (ACV) measurements with rotating scheimpflug camera (RSC) and to examine agreement with anterior segment optical coherence tomography (AS-OCT). Methods Thirty nine healthy normal subjects were recruited from the Eye Center of Tongren Hospital. ACV was measured using RSC and AS-OCT in a randomly selected eye for each subject. For RSC measurements, both automatic and manual ACV measurements and 2 independent operators' ACV measurements were obtained. All subjects were invited for 3 visits within a week to evaluate repeatability and reproducibility of ACV measurement by RSC. Agreement was evaluated between RSC and AS-OCT. Results Good repeatability and reproducibility were found for both automatic and manual ACV measurements obtained by RSC. For intrasession repeatability, coefficient of variation (CVw) and intraclass correlation coefficient (ICC) values for automatic were 3.52% and 0.98; the values for manual were 3.44% and 0.97, respectively. For intersession reproducibility, the respective CVw and ICC values were 3.96% and 0.96. Good agreement was also found in 2 operators for both automatic and manual ACV measurements; nevertheless, poor agreement was found between RSC and AS-OCT (95% confidence interval (CI) for agreement of automatic RSC measurement versus AS-OCT were -96.3 to 72.8 μl and 95% CI for agreement of manual RSC measurement versus AS-OCT were between -41.7 to 10.1 μl). Conclusions Both RSC automatic and manual ACV measurements showed good repeatability and reproducibility, and showed comparable agreement between 2 independent operators, but poor agreement was found between RSC and AS-OCT.

    Full Text Available Anterior palatal fistulae or residual anterior clefts are a frequent problem following palatoplasty. Various techniques have been used to repair such fistulae, each having its own advantages and disadvantages. We have successfully used orbicularis oris musculomucosal flap to close anterior fistula and residual clefts in 25 patients. This study shows the superiority of this flap over other techniques because of its reliable blood supply, easy elevation and transfer to fistula site and finally because it is a single-stage procedure.

    Full Text Available Enlargement of the mediastinal lymphatic glands is a common presentation of intrathoracic tuberculosis (TB in children. However, usually, the mediastinal TB nodes enlarge to 2.8 ± 1.0 cm. In this report, we describe a case of anterior mediastinal lymphnode TB seen as huge mass (7 cm on computed tomography (CT thorax without respiratory or food pipe compromise despite anterior mediastinum being an enclosed space. CT guided biopsy of the mass cultured Mycobacterium TB complex which was resistant to isoniazide, rifampicin, streptomycin ofloxacin, moxifloxacin, and pyrazinamide. Hence, we report primary multi drug resistant TB presenting as anterior mediastinal mass as a rare case report.

    Full Text Available A 29-year-old woman who underwent laser in situ keratomileusis (LASIK for myopic astigmatism in both eyes presented with severe pain, photophobia and decreased visual acuity in the left eye eight days after surgery. Examination revealed severe anterior uveitis with fibrinous exudates in the anterior chamber, flap edema and epithelial bullae. Laboratory investigations for uveitis were negative and the patient required systemic and intensive topical steroids with cycloplegics to control the inflammation. This case demonstrates that severe anterior uveitis may develop after LASIK and needs prompt and vigorous management for resolution.

  3. Multimodal emotion perception after anterior temporal lobectomy

    Full Text Available In the context of emotion information processing, several studies have demonstrated the involvement of the amygdala in emotion perception, for unimodal and multimodal stimuli. However, it seems that not only the amygdala, but several regions around it, may also play a major role in multimodal emotional integration. In order to investigate the contribution of these regions to multimodal emotion perception, five patients who had undergone unilateral anterior temporal lobe resection were exposed to both unimodal (vocal or visual and audiovisual emotional and neutral stimuli. In a classic paradigm, participants were asked to rate the emotional intensity of angry, fearful, joyful, and neutral stimuli on visual analog scales. Compared with matched controls, patients exhibited impaired categorization of joyful expressions, whether the stimuli were auditory, visual, or audiovisual. Patients confused joyful faces with neutral faces, and joyful prosody with surprise. In the case of fear, unlike matched controls, patients provided lower intensity ratings for visual stimuli than for vocal and audiovisual ones. Fearful faces were frequently confused with surprised ones. When we controlled for lesion size, we no longer observed any overall difference between patients and controls in their ratings of emotional intensity on the target scales. Lesion size had the greatest effect on intensity perceptions and accuracy in the visual modality, irrespective of the type of emotion. These new findings suggest that a damaged amygdala, or a disrupted bundle between the amygdala and the ventral part of the occipital lobe, has a greater impact on emotion perception in the visual modality than it does in either the vocal or audiovisual one. We can surmise that patients are able to use the auditory information contained in multimodal stimuli to compensate for difficulty processing visually conveyed emotion.

    Full Text Available Dirofilariasis is a parasitic infection of the carvivores that may present as a zoonotic infestation in humans. Systemic involvement in man is subcutaneous, pulmonary, or ocular. We report a rare occurrence of ocular dirofilariasis in a 25-year-old male patient who presented with pain and redness in the eye. A live, white, coiled, and highly motile worm was present in the anterior chamber. The worm, however, could not be detected in the anterior chamber, posterior segment, or the angle of the anterior chamber when the patient was taken to the operating room for surgical removal of the worm. The patient was made to lie prone till the worm reappeared in the anterior chamber and was removed by paracentesis. The worm was identified as Dirofilaria repens on the basis of microscopic and histopathological examination.

    The rehabilitation of an unesthetic smile in the anterior maxilla is always a clinical challenge, especially when an improper shape and size, old restorations, and unesthetic shading are present. In addition, an irregular gingival zenith contour in the anterior maxilla can affect the smile's harmony. Thus, detailed treatment planning is needed to define a functional and esthetic prosthetic rehabilitation. This study describes a clinical case in which a 55-year-old woman was rehabilitated using Digital Smile Design planning and full ceramic crowns (metal free) in the anterior zone of the maxilla and mandible. To normalize the gingival zenith, a dynamic compression technique was performed using provisional restorations to condition the gingival tissues and harmonize the proportional length of the anterior upper teeth.

    Blepharoptosis is a condition of inadequate upper eyelid position, with a downward displacement of the upper eyelid margin resulting in obstruction of the superior visual field. Levator resection is an effective technique that is routinely used to correct aponeurotic ptosis. The anterior levator resection is the procedure of choice in moderate blepharoptosis when there is moderate to good levator muscle function, furthermore, with an anterior approach, a greater resection can be achieved than by a conjunctival approach. The authors describe a modification in the Putterman technique with a resection done over a plicated elevator, plication that was suggested by Mustardè. The technique has been named as elevator muscle anterior resection. The elevator muscle anterior resection inspires from the Fasanella-Servat operation by the use of a clamp, making the operation simple and predictable. PMID:26703054

    Gassner, Holger G.; Schwan, Franziska; Schebesch, Karl-Michael

    2016-01-01

    Minimally invasive approaches are becoming increasingly popular to access the anterior skull base. With interdisciplinary cooperation, in particular endonasal endoscopic approaches have seen an impressive expansion of indications over the past decades. The more recently described transorbital approaches represent minimally invasive alternatives with a differing spectrum of access corridors. The purpose of the present paper is to discuss transorbital approaches to the anterior skull base in the light of the current literature. The transorbital approaches allow excellent exposure of areas that are difficult to reach like the anterior and posterior wall of the frontal sinus; working angles may be more favorable and the paranasal sinus system can be preserved while exposing the skull base. Because of their minimal morbidity and the cosmetically excellent results, the transorbital approaches represent an important addition to established endonasal endoscopic and open approaches to the anterior skull base. Their execution requires an interdisciplinary team approach. PMID:27453759

  17. Examination of the sprained ankle: Anterior drawer test or arthrography?

    International Nuclear Information System (INIS)

    The accuracy of the anterior drawer test for the diagnosis of recent lateral ligament tears in the ankle was evaluated in a series of 192 patients using surgical or arthrographic findings for reference. Considerable overlapping of results was obtained in ankles with and without ligament tear. Twenty-eight per cent of the anterior talofibular ligament tears, and 38% of the combined anterior talofibular and calcaneofibular tears were not detected, and single and combined tears could not be differentiated. It is concluded that the anterior drawer test is too unreliable as a basis for any decision regarding surgical treatment of a recent sprain. Therefore, arthrography is recommended as the method of choice in such cases of recent ankle sprain, where the need of surgery has to be supported by X-ray analysis. (orig.)

  18. Case study: limitations of panoramic radiography in the anterior mandible.

    LENUS (Irish Health Repository)

    Walker, Cameron

    2009-12-01

    Dental Panoramic Tomography (DPT) is a widely used and valuable examination in dentistry. One area prone to artefacts and therefore misinterpretation is the anterior region of the mandible. This case study discusses a periapical radiolucency related to lower anterior teeth that is discovered to be a radiographic artefact. Possible causes of the artefact include a pronounced depression in the mental region of the mandible or superimposition of intervertebral spaces. Additional limitations of the DPT image include superimposition of radio-opaque structures, reduced image detail compared to intra-oral views and uneven magnification. These problems often make the DPT inappropriate for imaging the anterior mandible. Clinical Relevance: Panoramic radiography is often unsuitable for radiographic examination of the anterior mandible.

    Objective. To detect histological characteristic of anterior cruciate ligament (ACL) and medial collateral ligament (MCL). Methods. In each of 20 skeletally mature male mongrels and 4 men, the ACL and MCL were examined by standard hematoxylin-eosin procedure and toluidine blue staining for histologic observation. Results. The fibroblasts in medial collateral are elongated to spindle shape and aligned in a row between the bundles of collagenous fibers. Toluidine blue staining is negative. The anterior cruciate ligament demonstrated more heterogenous cell types and arrangement. It had three major cell forms:spindle, round and ovoid type, which were shorter but greater than the cells in medial collateral ligament. Toluidine blue staining was positive in anterior cruciate ligament. Most cells in anterior cruciate ligament were enclosed within lacunae. Conclusion. This study suggests that the ACL has different histological characteristics from MCL, and is more cartilage-like in nature.

Given the frequency of early coronary reperfusion and risk of bleeding, it remains uncertain whether anticoagulation offers additional utility. We examined the effectiveness of anticoagulation therapy for the prevention of stroke after anterior MI. METHODS AND FINDINGS: We performed a population-based cohort analysis of 10,383 patients who survived hospitalization for an acute MI in Ontario, Canada from April 1, 1999 to March 31, 2001. The primary outcome was four-year ischemic stroke rates compared between anterior and non-anterior MI patients. Risk factors for stroke were assessed by multivariate Cox proportional-hazards analysis. Warfarin use was determined at discharge and followed for 90 days among a subset of patients aged 66 and older (n = 1483. Among the 10,383 patients studied, 2,942 patients survived hospitalization for an anterior MI and 20% were discharged on anticoagulation therapy. Within 4 years, 169 patients (5.7% were admitted with an ischemic stroke, half of which occurred within 1-year post-MI. There was no significant difference in stroke rate between anterior and non-anterior MI patients. The use of warfarin up to 90 days was not associated with stroke protection after anterior MI (hazard ratio [HR], 0.68; 95% confidence interval [CI], 0.37-1.26. The use of angiotensin-converting-enzyme inhibitors (HR, 0.65; 95% CI, 0.44-0.95 and beta-blockers (HR, 0.60; 95% CI, 0.41-0.87 were associated with a significant decrease in stroke risk. There was no significant difference in bleeding-related hospitalizations in patients who used warfarin for up to 90 days post-MI. CONCLUSION: Many practitioners still consider a large anterior-wall MI as high risk for potential LV thrombus formation and stroke. Among a cohort of elderly patients who survived an anterior

    A gummy smile is probably one of the most common causes of an unaesthetic smile. Causes include overeruption of maxillary anterior teeth and maxillary vertical excess. Intrusion of maxillary anterior teeth with Orthodontics and Le forte I superior repositioning may form a part of the solution. Of late the use of micro implants have improved the smile esthetics of borderline surgical cases by allowing the Orthodontist to intrude teeth more than what was possible with conventional Orthodontics.

    The objective was to evaluate the association, by MRI, of anterior calcaneal process fractures with tarsal coalitions, ankle sprains, and bifurcate ligament abnormalities. A retrospective review of 1,479 foot and ankle MR images was performed, over a period of 5 years, for isolated anterior process fractures of the calcaneus. Fifteen 1.5-T MR examinations were systematically evaluated by two radiologists in consensus. Marrow edema patterns, presence of a calcaneonavicular coalition, as well as bifurcate and anterior talofibular ligaments, were evaluated. There were 15 fractures of the anterior calcaneal process with an incidence of 1%. The average patient age was 51 years (range 25-82). Twelve patients were women and 3 were men. The majority of the fractures (14 out of 15) presented as an edema pattern on T2-weighted images, either diffuse (9 out of 15), or vertical (5 out of 15). One case did not show marrow edema, but rather a hypointense line. Nine patients (60%) demonstrated calcaneonavicular coalition and anterior calcaneal process fracture. In 6 patients (50%) the anterior talofibular ligament (ATFL) was thickened. Three patients did not have axial images, and were classified as non-conclusive for the ATFL evaluation. The bifurcate ligament was thickened with hyperintense signal demonstrating a sprain in 9 out of 13 (69%). Only 2 patients (16.5%) had an anterior calcaneal process fracture without any associated abnormality. We believe that there is a probable association of anterior process fractures and calcaneonavicular coalitions. We also feel, based on our results and the prior literature that there is likely also an association with both ATFL injuries and bifurcate ligament injuries. (orig.)

    2014-01-01

    Conclusions: The novel finding of an asymmetry in morphology of the anterior visual system following long-term survival from early monocular enucleation indicates altered postnatal visual development. Possible mechanisms behind this altered development include recruitment of deafferented cells by crossing nasal fibres and/or geniculate cell retention via feedback from primary visual cortex. These data highlight the importance of balanced binocular input during postnatal maturation for typical anterior visual system morphology.

    For decades spinal surgeons have attempted to design simple, single stage anterior internal fixation systems for the thoracic and lumbar spine. Early devices presented both biomechanical and technical problems. The AO Anterior Thoracolumbar Locking Plate (ATLP) was designed to solve some of the problems encountered with early anterior instrumentation. The ATLP system is constructed in Commercially Pure titanium. It is a low profile device indicated for use for unstable burst fractures in the anterior column; metastatic tumor management; and degenerative diseases of the thoracolumbar spine between levels T10 and L5. Implantation of the device involves direct anterior decompression with sagittal reduction and corpectomy. This is followed by grafting reconstruction, and plate fixation. This device has been implanted in 25 patients with an average follow-up of 38 months. There were five (5) broken screws in three (3) patients, and no broken plates. Implant related postoperative complications included two misplaced screws. Preliminary results indicate that the ATLP system seems to be a safe, low profile, MRI/CT compatible device that provides definitive single stage fixation of the anterior spinal column. PMID:9160452

    Purpose: We tried to find out the relevance of anterior mandibular body ostectomy in deformities of the mandible specially prognathism, which is primarily limited to anterior part only. Patients and Methods: Ten patients with skeletal deformity along with malocclusion, which was limited to anterior body of mandible were selected. Selected patients had proper molar interdigitation (even if class 3) and in general had anterior crossbite (except one). All patients had crossed their growth spurts and had no hormonal influence on facial deformity. Specific protocol, including cephelometric analysis cephalometry for orthognathic surgery, prediction tracing and model surgeries were devised. Pre and post-surgical orthodontics and body ostectomy were performed in all patients along with 18-month post-op follow-up. Results: There was significant reduction in prognathism and horizontal dysplasia in all ten patients. Anterior crossbite as well as axis of incisiors over mandibular plane was corrected in all patients due to decrease in length of mandibular body. All patients showed decreased facial height and better lip competence with intact posterior occlusion and no (negligible or transient) sensory loss. Conclusions: Our study could confirm that people whose deformity is limited to the anterior part of mandible with reasonable occlusion posteriorly can get satisfactory cosmetic and functional results through body ostectomy alone rather than going for surgical procedure in the ramal area, which is liable to cause sensory and occlusal disturbances.

  5. Anterior, posterior, left anterior oblique, and geometric mean views in gastric emptying studies using a glucose solution

    International Nuclear Information System (INIS)

    Previous research has shown that the single anterior view of the stomach overestimates the gastric half-emptying time of a solid meal compared to the geometric mean of the anterior and posterior views. Little research has been performed comparing the various views of gastric emptying of a glucose solution. After an overnight fast, 49 nondiabetic subjects were given a 450 ml solution containing 50 g of glucose and 200 μCi of technetium-99m sulfur colloid. Sequential 1-min anterior, posterior, and left anterior oblique views were obtained every 15 min. The mean percent solution remaining in the stomach for all three views differed from the geometric mean by 1.9% or less at all time points. Average gastric half-emptying times were: geometric mean, 62.7±3.3 min; anterior, 61.9±3.2 min; posterior, 63.5±3.5 min; and left anterior oblique, 61.6±3.3 min. These half-emptying times were not statistically different. For individual patients, differences between all three views and the geometric mean were not clinically important. Approximately 95% of all patients are expected to have gastric half-emptying times measured by any of the three single views within 17 min of the gastric half-emptying time obtained using the geometric mean. The imaging of gastric emptying using glucose solutions can be performed using a convenient single view which allows continuous dynamic imaging. (orig.)

    Anteriorly displaced anus is an anomaly that is debated with regard to its nomenclature, diagnosis and management. To describe MRI anatomy of the anal canal in children with anteriorly displaced anus and its impact on the process of defecation. We prospectively examined ten children (7 girls, 3 boys; age range 7 months to 8 years, mean 3 years) with anteriorly displaced anus between August 2009 and April 2012. Noncontrast MRI examinations were performed on a 1.5-T magnet. T1- and T2-weighted turbo spin-echo images were acquired in axial, sagittal and coronal planes of the pelvis. The anorectal angle and the relative hiatal distance were measured in mid-sagittal images, and compared with those of a control group using the Mann-Whitney test. In children with anteriorly displaced anus, no anatomical abnormality was depicted at the level of the proximal anal canal. However, the distal anal canal was displaced anteriorly, running out its external muscle cuff, which remained un-displaced at the usual site of the anus. This changes the orientation of the central axis of the anal canal by passing across instead of along the fibers of the longitudinal muscle coat. Children with anteriorly displaced anus had a more obtuse anorectal angle (mean 112.1 ), which was significantly greater than that of the control group (mean 86.2 ). MRI is a valuable tool in studying the anatomy of the anal canal in children with anteriorly displaced anus. The abnormal orientation of the longitudinal muscle across the anal canal can explain the obstructed defecation in these children. Based on this study, it might be of interest to use MRI in studying equivocal cases and children with unexplained constipation. (orig.)

    2016-01-01

    A routine eye examination of a 69-year-old man revealed a scleral perforation of one of the haptics of the anterior chamber intraocular lens (AC IOL) which had been implanted many years ago. The patient was asymptomatic with good visual acuity. His history was negative for any trauma, eye rubbing, topical corticosteroid use, or autoimmune disease. The horizontal and vertical white-to-white diameters of the cornea in the right eye were 11.5 and 10.5 mm, respectively. Anterior segment optical coherence tomography showed the anterior chamber length to be 12.28 mm horizontally and 10.63 mm vertically. The patient underwent an IOL exchange, and the length of the explanted AC IOL was measured to be 12 mm. We speculate that the AC IOL, which was vertically aligned, was oversized. This case demonstrates the need for proper sizing and positioning of an AC IOL. In complex cases where AC IOL may be used, measuring the horizontal and vertical lengths of the anterior chamber by anterior segment optical coherence tomography prior to surgery may be useful.

    A retrospective study was performed on patients who underwent myringoplasty for either anterior or subtotal perforations over an 8-year period (from 1994 till 2004). We used the KTP-laser assisted anterior anchoring technique combining with anterior "pull-back" method. Patients' ages ranged from 6-62 years (median 36.5). The mean follow-up period was 2.8 years (minimum 6 months). The audiological results were analysed with the "Pytel software", which was developed in our department. As for the procedure, the drum remnant was freed from the malleus handle with the use of the laser and elevated out of it's sulcus anterior-superiorly. Large fascia graft was fashioned with a split of 4-5 mm in the middle of one edge. The graft was placed using the underlay technique medial to the handle of the malleus. A pull-back tunnel was created at the border of the anterior quadrants to further facilitate the survival of the graft. In this series the graft taking rate was 100%. Reperforation due to an undersized fascia was observed in one case. Post-operative audiological results indicated no bone conduction threshold elevation in any frequencies. Using the laser, cochlear trauma can be prevented, double fixation of the drum prevents lateralisation and blunting. Wide canalplasty makes both the approach and the follow-up very easy. Thorough soft tissue and bone work is advantageous from the fascia taking rate point of view.

    Full Text Available A routine eye examination of a 69-year-old man revealed a scleral perforation of one of the haptics of the anterior chamber intraocular lens (AC IOL which had been implanted many years ago. The patient was asymptomatic with good visual acuity. His history was negative for any trauma, eye rubbing, topical corticosteroid use, or autoimmune disease. The horizontal and vertical white-to-white diameters of the cornea in the right eye were 11.5 and 10.5 mm, respectively. Anterior segment optical coherence tomography showed the anterior chamber length to be 12.28 mm horizontally and 10.63 mm vertically. The patient underwent an IOL exchange, and the length of the explanted AC IOL was measured to be 12 mm. We speculate that the AC IOL, which was vertically aligned, was oversized. This case demonstrates the need for proper sizing and positioning of an AC IOL. In complex cases where AC IOL may be used, measuring the horizontal and vertical lengths of the anterior chamber by anterior segment optical coherence tomography prior to surgery may be useful.

    Full Text Available Two female patients with histories of cancer who showed cryptogenic organizing pneumonia (COP complications and bilateral anterior uveitis with hypopyon were examined. Both patients had suffered from COP and received intermitted systemic corticosteroid administration (SCA. The first patient, a 65-year-old woman with a history of breast cancer, showed bilateral uveitis with hypopyon. The topical corticosteroid treatment was ineffective. After SCA for the treatment of COP was started, the hypopyon gradually dissipated. Upon termination of SCA, uveitis relapses were controlled by renewed SCA. The other patient, a 69-year-old woman with a history of ovarian cancer, showed bilateral anterior uveitis with hypopyon. Her intraocular outcome did not improve by the topical corticosteroid administration, but SCA that was applied to treat COP led to remission of uveitis. Imaging examinations, biochemical analysis, symptoms or HLA-B27 antigen screenings in either patient did not explain the development of uveitis. Bilateral anterior uveitis is commonly related to autoimmune disease or systemic syndrome. We report two cases with COP that developed bilateral anterior uveitis with hypopyon resistant to topical administration but responsive to systemic administration of corticosteroid. These findings suggest that COP can be associated with the etiology of anterior uveitis.

    Acute anterior uveitis (AAU) is the commonest type of uveitis and HLA-B27 AAU is the most frequently recognized type of acute anterior uveitis and anterior uveitis overall. Recent evidence indicates that acute anterior uveitis is a heterogenous disease, is polygenic and is frequently associated with the spondyloarthropathies (SpA). Studies of patients with AAU and animal models of disease indicate a role for innate immunity, the IL-23 cytokine pathway and exogenous factors, in the pathogenesis of both SpA and acute anterior uveitis. Recently described genetic associations cluster around immunologic pathways, including the IL-17 and IL-23 pathways, antigen processing and presentation, and lymphocyte development and activation. Patients with ankylosing spondylitis (AS) and AAU share other genetic markers, such as ERAP-1, which show strong evidence of gene-gene interaction and point to new mechanisms of disease pathogenesis. These observations have major implications for understanding the pathogenesis of HLA-B27 diseases, such as AAU, and may lead to the development of more specific therapy for AAU.

  18. Ophthalmohelioses and peripheral light focusing by the anterior eye

    1994-07-01

    A coincidence of the locations of foci of scattered light in the anterior eye with the usual locations of common sun-related eye conditions has been observed. These phenomena may explain the pathogenesis of pterygium and the initial location of certain cortical lens opacities and eyelid malignancies. Human and bovine eyes were used to demonstrate that the anterior eye acts as a side-on lens system. Light incident at the temporal limbus can be concentrated at the nasal limbus or beyond or at the nasal crystalline lens equator. The main pathways of light are transcameral and this is demonstrated by the use of baffles. Although this phenomenon is obvious with visible light, focusing of light at 308nm can be demonstrated. Computer-assisted optical ray tracing in a standard human anterior segment model showed that the peak intensity at the distal limbus is approximately twenty times that of the incident light intensity. The degree of limbal focusing is determined by corneal shape and anterior chamber depth. Such light focusing may be particularly injurious to corneal and lenticular epithelial stem cells. These observations provide circumstantial evidence that peripheral refraction phenomena are involved in the pathogenesis of the anterior ophthalmohelioses. Adequate lateral protection of the eye from increasing ultraviolet insolation may be prudent.

    Recovery following anterior cruciate ligament reconstruction is an arduous process that requires a significant mental and physical commitment to rehabilitation. Orthopaedic research in recent years has focused on optimizing anterior cruciate ligament surgical techniques; however, despite stable anterior cruciate ligament reconstructions, many athletes still never achieve their preinjury ability or even return to sport. Psychological factors associated with patient perceptions and functional outcomes following anterior cruciate ligament reconstruction are important to acknowledge and understand. Issues related to emotional disturbance, motivation, self-esteem, locus of control, and self-efficacy can have profound effects on patients' compliance, athletic identity, and readiness to return to sport. The psychological aspects of recovery play a critical role in functional outcomes, and a better understanding of these concepts is essential to optimize the treatment of patients undergoing anterior cruciate ligament reconstruction, particularly those who plan to return to sport. Identifying at-risk patients, encouraging a multidisciplinary approach to patient care, and providing early referral to a sports psychologist may improve patient outcomes and increase return-to-play rates among athletes.

The patient underwent an IOL exchange, and the length of the explanted AC IOL was measured to be 12 mm. We speculate that the AC IOL, which was vertically aligned, was oversized. This case demonstrates the need for proper sizing and positioning of an AC IOL. In complex cases where AC IOL may be used, measuring the horizontal and vertical lengths of the anterior chamber by anterior segment optical coherence tomography prior to surgery may be useful.

    Purpose. To evaluate anterior segment's structures by Pentacam in patients with tilted disc syndrome (TDS). Methods. Group 1 included forty-six eyes of forty-six patients who have the TDS. Group 2 including forty-six eyes of forty-six cases was the control group which was equal to the study group in age, gender, and refraction. A complete ophthalmic examination was performed in both groups. All cases were evaluated by Pentacam. The axial length (AL) of eyes was measured by ultrasound. Quantitative data obtained from these measurements were compared between two groups. Results. There was no statistically significant difference for age, gender, axial length, and spherical equivalent measurements between two groups (p = 0.625, p = 0.830, p = 0.234, and p = 0.850). There was a statistically significant difference for central corneal thickness (CCT), corneal volume (CV), anterior chamber angle (ACA), and pupil size measurements between two groups (p = 0.001, p = 0.0001, p = 0.003, and p = 0.001). Also, there was no statistically significant difference for anterior chamber depth (ACD), anterior chamber volume (ACV), and lens thickness (LT) measurements between two groups (p = 0.130, p = 0.910, and p = 0.057). Conclusion. We determined that CCT was thinner, CV was less, and ACA was narrower in patients with TDS. There are some changes in the anterior segment of the eyes with tilted disc. PMID:27648303

    The main aim of this research is finding the feature vectors of the anterior and posterior cruciate ligaments (ACL and PCL). These feature vectors have to clearly define the ligaments structure and make it easier to diagnose them. Extraction of feature vectors is obtained by analysis of both anterior and posterior cruciate ligaments. This procedure is performed after the extraction process of both ligaments. In the first stage in order to reduce the area of analysis a region of interest including cruciate ligaments (CL) is outlined in order to reduce the area of analysis. In this case, the fuzzy C-means algorithm with median modification helping to reduce blurred edges has been implemented. After finding the region of interest (ROI), the fuzzy connectedness procedure is performed. This procedure permits to extract the anterior and posterior cruciate ligament structures. In the last stage, on the basis of the extracted anterior and posterior cruciate ligament structures, 3-dimensional models of the anterior and posterior cruciate ligament are built and the feature vectors created. This methodology has been implemented in MATLAB and tested on clinical T1-weighted magnetic resonance imaging (MRI) slices of the knee joint. The 3D display is based on the Visualization Toolkit (VTK).

    No study reports the histological features of the various zone of the anterior tubercle of the tibia in the different stages of the Osgood-Schlatter (O-S) lesion. For this reason we carried on an histological study. Specimens were taken from 13 patients with O-S lesion prior to surgery. In 4 cases in the apophyseal stage lesions were present in an altered fibrocartilage anterior to the ossification centre. In 9 cases in the epiphyseal stage varying degrees of reparative tissues were observed in the bed of the fragment of the secondary ossification centre. In 3 of them a zone of lesion was observed within the fibrocartilage anterior to the ossification centre. These results suggest that the slippage of the patellar tendon insertion may be progressive and caused by pathological fibrocartilage. PMID:21669134

    During the first step of cataract surgery, the lens capsule is perforated and a circular hole is created with a sharp instrument, a procedure called capsulorhexis. To develop automated systems that can assist ophthalmologists during capsulorhexis, the forces required must be quantified. This study investigates perforation forces of the central anterior lens capsule in porcine eyes, which are used as a conservative model for the human eye. A micro-mechanical characterisation method is presented that measures capsular bag perforation forces with a high precision positioning and high-resolution force sensing system. The force during perforation of the anterior lens capsule was measured with various sized needles and indentation speeds and is found to be 15-35mN. A bio-mechanical model is identified that describes an exponential correlation between indentation force and depth, indicating strain hardening behaviour of the porcine anterior lens capsule.

    Anterior megalophthalmos (AM) is an uncommon developmental anomaly of the anterior segment of the eye with a constellation of findings that includes enlarged cornea,deep anterior chamber,posterior positioning of the iris and lens,iris stroma atrophy,hypoplasia of iris dilator,pupil displacement,large capsular bag,lens subluxation,prematurely cataract and the tendency to retinal detachment.AM,especially when symptoms are mild,is not an easy disease to diagnose.We present 3 AM cases that were misdiagnosed as congenital cataract with weak zonule and megalocornea.Intraocular lenses (IOLs) dislocated after standard cataract surgeries and subsequent surgery (replacing the dislocated IOLs with iris-claw intraocular lenses) achieved satisfactory outcome.Although rare,AM should be included in the differential diagnosis of enlarged cornea and we recommend implanting Artisan lens in AM patients.

    Compartment syndrome rarely follows anterior cruciate ligament reconstruction. However, when it does, it may result in mononeuropathies that are amenable to neurolysis. The authors of this study present an 18-yr-old woman who sustained a right anterior cruciate ligament tear and underwent uneventful anterior cruciate ligament reconstruction using femoral and popliteal nerve blocks. Postoperatively, she developed compartment syndrome requiring emergent fasciotomies. At 11 wks after fasciotomy, results of electrophysiologic tests showed evidence of severe fibular and tibial neuropathies. Magnetic resonance images showed extensive tricompartmental myonecrosis. Fibular and tibial neurolysis as well as decompression were performed, followed by intensive outpatient rehabilitation. At the 6-mo follow-up, she reported resolution of pain as well as significant improvement in sensation, strength, and function. Early recognition and intervention are crucial to prevent serious neurologic damage. Excessive tourniquet pressure and anesthetic nerve blocks may have been responsible.

    Full Text Available Objective To study the clinical manifestations, pathologic features, diagnosis, treatment and prognosis of primary synovial sarcoma in the anterior mediastinum. Methods A case of primary synovial sarcoma in the anterior mediastinum was reported. Clinical features, imaging manifestations, pathology features and therapeutic effect were analysed and the relevant literature was reviewed. Results A 48-year-male patient was admitted with complaint of right chest pain for 4 days. Chest computerized tomography revealed a large mass located at the right anterior mediastinum, and it was primarily diagnosed as invasive thymoma. Pathological examination by CT-guided percutaneous needle biopsy manifested that, under microscope, the tumor cells were short and spindle in shape forming a nest structure, suggested it was a thymoma. The patient then underwent resection of thymoma with removal of fat and connective tissue in the anterior mediastinum. During the operation the size of the tumor was 15cm×15cm×10cm, being located at the anterior mediastinum, and it tended to bleed. The diagnosis of primary monophasic synovial sarcoma in the mediastinum was confirmed by postoperative/pathology examination. Immunohistochemistry staining showed that the tumor cells were positive for the markers Bcl-2 and EMA, but negative for the markers CK (pan and S100. The patient suffered from local recurrence with metastases to lung 4 months after surgery. The patient received 2 chemotherapeutic courses with ifosfamide, epirubicin and cisplatin. He died 6 months after surgery. Conclusion Primary synovial sarcoma in the anterior mediastinum is an extremely rare and highly malignant tumor with poor prognosis. The diagnosis depends on the pathological features, immunohistochemistry and RT-PCR. Radical resection combined with comprehensive treatment may improve the survival rate.

    Objective: To evaluate the safety and efficacy of new modality of anterior skull base repair,namely sandwich-like reconstruction of anterior skull base defects. Methods: A retrospective analysis of patients who underwent transcranial or transcranial-facial resections of malignant or benign aggressive tumors involving the anterior skull base was conducted in our department. We used the sandwich-like reconstruction, using pedicled pericranial flap, frontal muscle flap and free abdominal adipose tissue between them, to separate of cranial cavity and aerodigest tract and keep the frontal lobes in place following resections of anterior skull base tumors. Results: From October, 1984 to October, 1998, 116 patients underwent transcranial or transcranialfacial approach for the resection of malignant or aggressive benign tumor, and sandwich-like repairs were performed for the anterior skull base defect. 54 (46.6 % ) patients had previous operation, with a maximum of 5 surgeries. The average age of patients was 35.9 years old, ranging form 6 to 73 years old. Forty-eight (41.4%)patients had malignant neoplasmas, and sixty-eight (58.6%) patients had benign aggressive tumors. In our series, with the maximal follow-ups for as long as 14 years, NO one had early failure of the one-stage reconstruction. CSF fluid leakage was not encountered, nor was ascending bacterial meningitis observed. No immediate or delayed prolapse of dura or frontal lobes was observed. Conclusion: We conclude that the sandwich-like reconstruction, using pericranial flap, frontal muscle flap and free abdominal adipose between them, is an extremely safe and effective procedure for the repair of skull base defect, even when tumor extensively involves anterior skull base.

    Full Text Available Background/Aim. An important element of prosthetic treatment of edentulous patients is selecting the size of anterior artificial teeth that will restore the natural harmony of one’s dentolabial structure as well as the whole face. The main objective of this study was to determine the correlation between the inner canthal distance (ICD and interalar width (IAW on one side and the width of both central incisors (CIW, the width of central and lateral incisors (CLIW, the width of anterior teeth (ATW, the width between the canine cusps (CCW, which may be useful in clinical practice. Methods. A total of 89 subjects comprising 23 male and 66 female were studied. Their age ranged from 19 to 34 years with the mean of 25 years. Only the subjects with the preserved natural dentition were included in the sample. All facial and intraoral tooth measurements were made with a Boley Gauge (Buffalo Dental Manufacturing Co., Brooklyn NY, USA having a resolution of 0.1mm. Results. A moderate correlation was established between the interalar width and combined width of anterior teeth and canine cusp width (r = 0.439, r = 0.374. A low correlation was established between the inner canthal distance and the width of anterior teeth and canine cusp width (r = 0.335, r = 0.303. The differences between the two genders were highly significant for all the parameters (p < 0.01. The measured facial distances and width of anterior teeth were higher in men than in women. Conclusion. The results of this study suggest that the examined interalar width and inner canthal distance cannot be considered reliable guidelines in the selection of artificial upper anterior teeth. However, they may be used as a useful additional factor combined with other methods for objective tooth selection. The final decision should be made while working on dentures fitting models with the patient’s consent.

    Introduction Gonioscopy is the gold standard in assessing anterior chamber angles. However, interobserver variations are common and there is a need for reliable objective method of assessment. Aim To compare the anterior chamber angle by gonioscopy and Spectral Domain Optical Coherence Tomography (SD-OCT) in individuals with shallow anterior chamber. Materials and Methods This comparative observational study was conducted in a rural tertiary multi-speciality teaching hospital. A total of 101 eyes of 54 patients with shallow anterior chamber on slit lamp evaluation were included. Anterior chamber angle was graded by gonioscopy using the shaffer grading system. Angles were also assessed by SD-OCT with Trabecular Iris Angle (TIA) and Angle Opening Distance (AOD). Chi-square test, sensitivity, specificity, positive and negative predictive value to find correlation between OCT parameters and gonioscopy grading. Results Females represented 72.7%. The mean age was 53.93 ±8.24 years and mean anterior chamber depth was 2.47 ± 0.152 mm. Shaffer grade ≤ 2 were identified in 95(94%) superior, 42(41.5%) inferior, 65(64.3%) nasal and 57(56.4%) temporal quadrants. Cut-off values of TIA ≤ 22° and AOD ≤ 290 μm were taken as narrow angles on SD-OCT. TIA of ≤ 22° were found in 88(92.6%) nasal and 87(87%) temporal angles. AOD of ≤ 290 μm was found in 73(76.8%) nasal and 83(83%) temporal quadrants. Sensitivity in detecting narrow angles was 90.7% and 82.2% for TIA and AOD, while specificity was 11.7% and 23.4%, respectively. Conclusion Individuals were found to have narrow angles more with SD-OCT. Sensitivity was high and specificity was low in detecting narrow angles compared to gonioscopy, making it an unreliable tool for screening. PMID:27190851

    Full Text Available ABSTRACT Purpose: To evaluate the difference in terms of refractive errors and anterior segment parameters between schizophrenic patients and healthy volunteers. Methods: This study compared 70 patients (48 men who were diagnosed with schizophrenia with a control group of 60 (35 men who were similar in terms of age, gender, education, and socioeconomic level. Anterior segment examination was performed using a Scheimflug system. Axial length and lens thickness (LT were measured using optic biometry. The following tests were administered to the psychiatric patient group: Brief Psychiatric Rating Scale (BPRS, Scale for the Assessment of Negative Symptoms (SANS, and Scale for the Assessment of Positive Symptoms (SAPS. Results: Mild myopia was detected in both the schizophrenic and control groups, with no statistically significant difference (p>0.005. Corneal volume (CV, anterior chamber volume (ACV, anterior chamber depth (ACD, and central corneal thickness (CCT values were lower in the schizophrenic group, and there was a statistically significant between-group difference (p=0.026, p=0.014, p=0.048, and p=0.005, respectively. LT was greater in schizophrenics, and the difference was found to be statistically significant (p=0.006. A statistically significant negative correlation was found between SAPS and cylinder values (p=0.008. The axial eye length, cylinder value, pupil diameter, mean keratometric value, and anterior chamber angle revealed no statistically significant difference between the groups (p>0.05. Conclusion: No statistically significant difference was detected in terms of refraction disorders between schizophrenics and the healthy control group, while some differences in anterior chamber parameters were present. These results demonstrate that schizophrenics may exhibit clinical and structural differences in the eye.

    There is sparse information concerning approaches to metachronous lung cancer in patients who had a previous pneumonectomy for lung carcinoma. We describe the case of a 55-year-old woman who underwent a left pneumonectomy for lung carcinoma. Four years later, a radiological examination revealed a hypermetabolic nodule in the right upper lobe, which was located in the left hemithorax because of right lung hyperinflation and a mediastinal shift to the left. Wedge resection was carried out through a left anterior mediastinotomy. We believe that an anterior mediastinotomy represents a valuable option for the management of recurrent lung cancer after previous surgery. PMID:26124429

    2001-11-01

    We documented the spacing and distribution of perikymata on the buccal enamel surface of fossil hominin anterior teeth with reference to a sample of modern human and modern great ape teeth. A sample of 27 anterior teeth attributed to Australopithecus (5 to A. afarensis, 22 to A. africanus) and of 33 attributed to Paranthropus (6 to P. boisei, and 27 to P. robustus) were replicated and sputter-coated with gold to enable reflected light microscopy of their surface topography. Anterior teeth were then divided into 10 equal divisions of buccal crown height. The total perikymata count in each division of crown height was recorded using a binocular microscope fitted with a vernier micrometer eyepiece. Then the mean number of perikymata per millimeter was calculated for each division. Similar comparative data for a modern sample of 115 unworn human anterior teeth and 30 African great ape anterior teeth were collected from ground sections. Perikymata counts in each taxon (together with either known or presumed periodicities of perikymata) were then used to estimate enamel formation times in each division of crown height, for all anterior tooth types combined. The distributions of these estimates of time taken to form each division of crown height follow the same trends as the actual perikymata counts and differ between taxa in the same basic way. The distinction between modern African great apes and fossil hominins is particularly clear. Finally, we calculated crown formation times for each anterior tooth type by summing cuspal and lateral enamel formation times. Estimates of average crown formation times in australopiths are shorter than those calculated for both modern human and African great ape anterior teeth. The data presented here provide a better basis for exploring differences in perikymata spacing and distribution among fossil hominins, and provide the first opportunity to describe four specimens attributed to Homo in this context. Preliminary data indicate that

    Injury to the axillary artery is a rare complication of anterior shoulder dislocation. Open surgical repair is technically demanding because of the anatomical position of the vessel and the propensity for concomitant injuries. Standard surgical exposure techniques involve extensive dissection, including a combination of supraclavicular or infraclavicular incision, median sternotomy, and thoracotomy causing significant morbidity and mortality rates. Endovascular techniques may offer an alternative to these surgically demanding procedures. We present a patient with a traumatic dissection of the axillary artery following anterior shoulder dislocation who was successfully managed with an endovascular stent. PMID:18411587

  4. Clearance from the anterior chamber of RBCs from human diabetics

    International Nuclear Information System (INIS)

    Erythrocytes from diabetic patients manifest decreased deformability and increased adherence. These abnormal membrane properties may diminish the ability of erythrocytes (RBCs) from diabetics to undergo deformation in passage through the trabecular meshwork. Using sodium chromate Cr 51-labeled RBCs from type I diabetic patients with proliferative retinopathy and normal control subjects, we studied RBC clearance from the rabbit anterior chamber. The mean time for 50% clearance (T50) of RBCs from diabetics (76 hours) was significantly longer than that for RBCs from normal subjects (19.5 hours). In this model, RBCs from diabetics have a slower clearance from the anterior chamber than do RBCs from normal subjects

  5. Proprioception in anterior cruciate ligament deficient knees and its relevance in anterior cruciate ligament reconstruction

    2011-01-01

    Full Text Available Injury to the anterior cruciate ligament (ACL not only causes mechanical instability but also leads to a functional deficit in the form of diminished proprioception of the knee joint. "Functional" recovery is often incomplete even after "anatomic" arthroscopic ACL reconstruction, as some patients with a clinically satisfactory repair and good ligament tension continue to complain of a feeling of instability and giving way, although the knee does not sublux on clinical testing. Factors that may play a role could be proprioceptive elements, as the intact ACL has been shown to have significant receptors. Significant data have come to light demonstrating proprioceptive differences between normal and injured knees, and often between injured and reconstructed knees. ACL remnants have been shown to have proprioceptive fibers that could enhance functional recovery if they adhere to or grow into the reconstructed ligament. Conventionally the torn remnants are shaved off from the knee before graft insertion; modern surgical techniques, with remnant sparing methods have shown better outcomes and functional recovery, and this could be an avenue for future research and development. This article analyzes and reviews our understanding of the sensory element of ACL deficiency, with specific reference to proprioception as an important component of functional knee stability. The types of mechanoreceptors, their distribution and presence in ACL remnants is reviewed, and suggestions are made to minimize soft tissue shaving during ACL reconstruction to ensure a better functional outcome in the reconstructed knee.

    The purpose of this work is the clinical commissioning of a recently developed in vivo range verification system (IRVS) for treatment of prostate cancer by anterior and anterior oblique proton beams. The IRVS is designed to perform a complete workflow for pre-treatment range verification and adjustment. It contains specifically designed dosimetry and electronic hardware and a specific software for workflow control with database connection to the treatment and imaging systems. An essential part of the IRVS system is an array of Si-diode detectors, designed to be mounted to the endorectal water balloon routinely used for prostate immobilization. The diodes can measure dose rate as function of time from which the water equivalent path length (WEPL) and the dose received are extracted. The former is used for pre-treatment beam range verification and correction, if necessary, while the latter is to monitor the dose delivered to patient rectum during the treatment and serves as an additional verification. The entire IRVS workflow was tested for anterior and 30 degree inclined proton beam in both solid water and anthropomorphic pelvic phantoms, with the measured WEPL and rectal doses compared to the treatment plan. Gafchromic films were also used for measurement of the rectal dose and compared to IRVS results. The WEPL measurement accuracy was in the order of 1 mm and after beam range correction, the dose received by the rectal wall were 1.6% and 0.4% from treatment planning, respectively, for the anterior and anterior oblique field. We believe the implementation of IRVS would make the treatment of prostate with anterior proton beams more accurate and reliable. PMID:27002470

    Full Text Available OBJECTIVE: To evaluate the complications of anterior approach to the cervical spine in patients who underwent cervical arthrodesis with instrumentation. METHODS: Prospective and descriptive study was conducted from January 2009 to April 2010. All patients who underwent arthrodesis of the cervical spine by anterior approach were included, regardless the diagnosis. Access was made by the anterior approach on the right side. We evaluated the number of operated levels (1, 2 or 3 levels and, the type of procedure performed: discectomy and placement of cage and plate (D+C+P, discectomy with placement of a cage (D+C or corpectomy with placement of cage and plate (C+C+P. All complications related to surgical approach were reported. RESULTS: We studied 34 patients, 70% male. The average age was 50 years and mean follow-up was 8 months. Eighteen percent of patients had complications, distributed as follows: dysphasia (33% and dysphonic (67%. Among patients who developed complications, most underwent to D+C+P (83% and no complications were found in patients where no cervical plate was used. Regarding levels, both complications were identified in patients operated to one or two levels. However, in patients operated on three levels, only dysphonia was identified. CONCLUSION: The most frequent complication was dysphonia. Patients who presented more complications were those undergoing discectomy and fusion with cage and anterior cervical plate. All cases of dysphonia were in this group. The number of accessible levels does not seem to have affected the incidence of complications.

  10. Holistic approach to understanding anterior knee pain. Clinical implications.

    2014-10-01

    Anterior knee pain is one of the most frequent reasons for consultation within knee conditions. The aetiology is not well known, which explains the sometimes unpredictable results of its treatment. Normally, when we see a patient in the office with anterior knee pain, we only study and focus on the knee. If we do this, we are making a big mistake. We must not forget to evaluate the pelvis and proximal femur, as well as the psychological factors that modulate the course of the illness. Both the pelvifemoral dysfunction as well as the psychological factors (anxiety, depression, catastrophization and kinesiophobia) must be included in our therapeutic targets of the multidisciplinary treatment of anterior knee pain. We must not only focus on the knee, we must remember to "look up" to fully understand what is happening and be able to solve this difficult problem. The aetiology of anterior knee pain is multifactorial. Therefore, diagnosis and treatment of patellofemoral disorders must be individualized. Our findings stress the importance of tailoring physiotherapy, surgery and psycho-educational interventions to each patient.

    Wernicke's aphasia occurs after a stroke to classical language comprehension regions in the left temporoparietal cortex. Consequently, auditory-verbal comprehension is significantly impaired in Wernicke's aphasia but the capacity to comprehend visually presented materials (written words and pictures) is partially spared. This study used functional magnetic resonance imaging to investigate the neural basis of written word and picture semantic processing in Wernicke's aphasia, with the wider aim of examining how the semantic system is altered after damage to the classical comprehension regions. Twelve participants with chronic Wernicke's aphasia and 12 control participants performed semantic animate-inanimate judgements and a visual height judgement baseline task. Whole brain and region of interest analysis in Wernicke's aphasia and control participants found that semantic judgements were underpinned by activation in the ventral and anterior temporal lobes bilaterally. The Wernicke's aphasia group displayed an 'over-activation' in comparison with control participants, indicating that anterior temporal lobe regions become increasingly influential following reduction in posterior semantic resources. Semantic processing of written words in Wernicke's aphasia was additionally supported by recruitment of the right anterior superior temporal lobe, a region previously associated with recovery from auditory-verbal comprehension impairments. Overall, the results provide support for models in which the anterior temporal lobes are crucial for multimodal semantic processing and that these regions may be accessed without support from classic posterior comprehension regions.

    The human anterior cingulate cortex is distinguished by the presence of an unusual cell type, a large spindle neuron in layer Vb. This cell has been noted numerous times in the historical literature but has not been studied with modern neuroanatomic techniques. For instance, details regarding the neuronal class to which these cells belong and regarding their precise distribution along both ventrodorsal and anteroposterior axes of the cingulate gyrus are still lacking. In the present study, morphological features and the anatomic distribution of this cell type were studied using computer-assisted mapping and immunocytochemical techniques. Spindle neurons are restricted to the subfields of the anterior cingulate cortex (Brodmann's area 24), exhibiting a greater density in anterior portions of this area than in posterior portions, and tapering off in the transition zone between anterior and posterior cingulate cortex. Furthermore, a majority of the spindle cells at any level is located in subarea 24b on the gyral surface. Immunocytochemical analysis revealed that the neurofilament protein triple was present in a large percentage of these neurons and that they did not contain calcium-binding proteins. Injections of the carbocyanine dye DiI into the cingulum bundle revealed that these cells are projection neurons. Finally, spindle cells were consistently affected in Alzheimer's disease cases, with an overall loss of about 60%. Taken together, these observations indicate that the spindle cells of the human cingulate cortex represent a morphological subpopulation of pyramidal neurons whose restricted distribution may be associated with functionally distinct areas.

Methods: A survey evaluating the preoperative examination, technique of anterior colporrhaphy, operation choice and postoperative care was presented to surgeons. We contacted via directly, mail or telephone. We used 28 item questionnaire. Results: Majority (87.9% was composed of young gynecologists. Urologists composed of the 9.5% of the study population. The rate of paravaginal defect evaluation was 75.9% and mostly by inspection the presence of vaginal rugae. The use of transperineal 3D pelvic floor ultrasonography was low (5.7%. The evaluation of levator ani muscle defect was 46.6%. The usage of the transperineal 3D ultrasonography for levator ani muscle defect was 19 percent of operators. There were diversity in use of hydrodissection, fascial plication, excision of vaginal mucosa and suture choice. Usage of mesh for anterior colporrhaphy was limited (17.8% and mostly in recurrent cases (12.2%. Paravaginal defect repair rate was 31.9%. The urinary catheter was generally removed one or two day after operation. Vaginal pack usually removed 24 hours after. Conclusion: Several techniques and approaches for anterior vaginal wall repair among operators in Turkey. The variety of techniques suggested that there is no consensus on best surgical technique.

    Full Text Available Purpose: The aim of this study was to investigate possible predictive factors related to anterior chamber fibrin formation after vitreoretinal surgery in a large series of patients. Methods: The data of 185 eyes of 185 patients submitted to vitreoretinal surgery was reviewed. The following variables were evaluated: the postoperatively presence of fibrin, age, diabetes mellitus, the vitrectomy system gauge (20, 23 or 25 gauge, the type of vitreous substitute, the influence of prior surgical procedures and the combination with cataract extraction. To evaluate predictive factors for anterior chamber fibrin formation, univariate analysis was performed. A multivariate stepwise logistic regression model was adjusted to investigate factors associated with fibrin formation (p<0.05. Results: Fibrinoid anterior chamber reaction was found in 12 (6.4% patients. For multivariate logistic regression analysis, balanced salt solution (BSS, the chance of fibrin occurrence was 5 times greater (odds ratio 4.83, CI 95% 1.302 - 17.892; p=0.019, while combination with phacoemulsification increased the chance of fibrin formation by 20 times (odds ratio 20, CI 95% 2.480 - 161.347; p=0.005. No significant difference was found regarding other variables. Conclusion: Anterior chamber fibrin formation is an unwanted complication after vitreoretinal surgery. Factors such as combined performance of phacoemulsification and the use of balanced salt solution as a vitreous substitute may predispose the occurrence of this complication.

    2016-02-01

    The anterior fixation of the anterior process of the malleus has been studied in a number of Cetartiodactyla. This anterior process, also known as processus gracilis, is provided by the prearticular (gonial), a dermal bone, whereas the cartilage of Meckel becomes resorbed in perinatal ontogenetic stages. Posteriorly, the prearticular fuses with the cartilaginous caput of the malleus; rostrally, the prearticular (= processus gracilis) is always fixed to the anterior crus of the ectotympanic by an extremely thin splint (thickness fused to the adjacent bones already in juveniles. However, in ruminants, the tegmen tympani tends to disappear and the processus internus praearticularis appears as relatively small bony knob at the floor of the medial cranial cavity, and it seems not to be fused to the surrounding bones; in later age stages, it may become secondarily overgrown by the petrosal. This dorsally exposed processus internus praearticularis seems to be a synapomorphy of the Ruminantia. The functional meaning of this internal process of the prearticular, which is also developed to a minor degree in Carnivora, remains unclear at the moment - but we present some speculations about this.

  11. MR imaging of anterior cruciate ligament injury: associated findings

    International Nuclear Information System (INIS)

    Authors investigated the associated findings and their value in the diagnosis of anterior cruciate ligament (ACL) injury in MR image. The knee MR images of 47 patients with ACL injury (complete;24, partial;23) and 61 patients with normal ACL confirmed by the knee arthroscopy or operation were reviewed retrospectively. The degree of anterior translocation of tibia and the degree of posterior cruciate ligament (PCL) buckling were evaluated. The prevalence and pattern of associated adjacent bone, ligament and meniscus injuries were studied. The means(± 2 standard errors) of anterior translocation were different significantly in statistical analysis (ρ < 0.001, student t-test) between injury group (7.51 ± 1.16 mm) and normal group (-0.56 ± 0.92mm). In the level of 5mm of anterior translocation for the criteria of ACL injury, the sensitivity, specificity, accuracy were 78.7%, 89.5%, 84.3% for each. The means of PCL buckling ratio were also different statistically between injury group(0.23 ± 0.02) and normal group(0.17 ± 0.01)(ρ < 0.001). In the level of 0.20 for diagnostic criteria of ACL injury, the sensitivity, specificity, accuracy were 71.4%, 83.6%, 78.4% for each. Thirty one medial meniscus tear (66%), thirteen lateral meniscus tear (28%), ten medial collateral ligament injury (28%), one PCL injury(2%) were associated with ACL injury. The twenty nine bone marrow changes were found in twenty patients (43%) which included acutely injured seven patients. In acute cases, the bone marrow changes were depicted as diffuse or focal high signal intensity lesions in lateral femoral or tibial condyles in contrast to the changes in chronic cases depicted as focal low signal intensity lesions in variable location. Lateral femoral condylar notch depression were found in nine patients (19%) and avulsion fractures of anterior tibial spine in four patients(9%). The associated findings with ACL injury (anterior translocation, buckling of PCL, associated bone, ligament and

    Different clinical tests have been suggested in the literature as significant indicators of anterior shoulder instability. Sometimes patients with recurrent anterior shoulder instability may show some muscular guarding thus making the evaluation of specific clinical tests very difficult. These patients may also report a medical history with posterior shoulder pain that can be also elicited during some clinical manoeuvres. From September 2005 to September 2006 we prospectively studied patients who underwent an arthroscopic anterior capsuloplasty. Shoulder clinical examination was performed including anterior shoulder instability tests (drawer, apprehension and relocation tests). Furthermore the exam was focused on the presence of scapular dyskinesia and posterior shoulder pain. The patients were also evaluated with ASES, Rowe, SST (Simple Shoulder Test), Constant and UCLA (University of California at Los Angeles) scoring system preoperatively and at the latest follow-up time. In the period of this study we observed 16 patients treated for anterior gleno-humeral arthroscopic stabilisation, who preoperatively complained also of a posterior scapular pain. The pain was referred at the level of lower trapezium and upper rhomboids tendon insertion on the medial border of the scapula. It was also reproducible upon local palpation by the examiner. Four of these patients also referred pain in the region of the insertion of the infraspinatus and teres minor. After arthroscopic stabilisation the shoulder was immobilised in a sling with the arm in the neutral rotation for a period of 4 weeks. A single physician supervised shoulder rehabilitation. After a mean time of 6.8 months of follow-up, all the shoulder scores were significantly improved and, moreover, at the same time the patients referred the disappearance of the posterior pain. Posterior scapular shoulder pain seems to be another complaint and sign that can be found in patients affected by anterior shoulder instability

    Objective To investigate the efifcacy and complications of preoperative arterial embolization in the surgical treatment of high sacral tumors. Methods The data of 37 patients with high sacral tumors who underwent surgical resection in our hospital between January 2006 and December 2011 were retrospectively analyzed. Preoperative arterial embolization were performed in all the patients and surgery were performed within the following 24 hours. The data of surgical time, blood loss, transfusion volume, and the postoperative complications were collected by reviewing the arterial embolization record, image, operation record, progress notes, nursing records and etc. Results Angiography clearly demonstrated the blood supply of the tumor and the dimension of the lesion. The tumor stain was markedly reduced after selective embolization in angiography. The volume of the tumor was decreased, the margin of the tumor became clear, and blood loss during the exposure was reduced. The surgical time was ( 147.97±38.99 ) min, blood loss was ( 1932.35±1293.27 ) ml, transfusion volume was ( 1296.00±938.00 ) ml. No serious embolization-associated complications were observed in all the patients. The incidence of delayed wound healing was 18/37 ( 49%), and the incidence of wound infection was 8/37 ( 22%). Conclusions Preoperative arterial embolization is an effective supplementary means for the surgery of high sacral tumor, which can shorten the surgical time, reduce the blood loss and the transfusion volume.

    Full Text Available Introduction: Bilateral shoulder dislocation are most commonly posterior type. These are most commonly due to seizure disorder and electrocution. Anterior shoulder dislocations occurring bilaterally without any predisposing factors are very rare. These types of injuries are due to trauma with a unique mechanism of injury. To best of our knowledge there are only few cases of similar kind are reported in literature. We hereby report a interesting case of posttraumatic, bilateral anterior dislocation of shoulder without associated fracture in a 45 old women without any predisposing pathoanatomy.Case Report: A 45-year-old women presented to casualty with sudden onset of pain and restriction of movement in both shoulders fallowing trauma. Immediately post trauma she had severe pain and restriction of both shoulders. On examination arms were abducted and externally rotated. Bilateral shoulder movements were painful and restricted . There was loss of round contour of shoulder with increased vertical diameter of axilla anteriorly. Radiological examination revealed bilateral anterior dislocation of the shoulders without any associated fractures. Closed reduction done by Milch technique after intraraticular lignocaine injection. MRI of bilateral shoulder showed no pathological lesion. Both shoulders were immobilized with a shoulder immobilizer for three weeks.Conclusion: Most of the bilateral shoulder dislocations are posterior type seen in seizure disorders. Bilateral traumatic anterior shoulder dislocations are rare and are seen as a result of unique mechanism of injury. In our case patient had a fall on her elbows causing forced extension. If diagnosed and treated promptly completely normal function of the shoulders can be restored.

    Full Text Available BACKGROUND Anterior Cruciate Ligament (ACL tear is the most common serious ligamentous injury to the knee joint. Anterior Cruciate Ligament (ACL injury is quite common among young active population, athletes and contact sports. The exact incidence of anterior cruciate ligament tears is not known as the cases are being under reported. The ACL is the primary stabilizer against anterior translation of the tibia on the femur and is important in counteracting rotation and valgus stress. MATERIALS AND METHODS Between November 2012 to October 2014, 34 consecutive patients who underwent arthroscopic assisted ACL reconstructions in the Department of Orthopedics and Traumatology, King George Hospital, Visakhapatnam were the material in our study. Age groups between 18 to 45 years considered. We utilised both BPTB and Quadrupled hamstring graft depending on the patient’s age, outcome testing in all cases was performed at the latest follow-up (at least 6 months. Post-operative physiotherapy rehabilitation protocol followed for 06 months. RESULTS Standard protocol of Lysholm and IKDC knee scoring system were used for evaluation of the results of the surgery during followup. Patients were evaluated periodically at preop, 3 months, 6 months, 12 months, 18 months and 24 months. CONCLUSION Patients with isolated ACL injury had better outcome compared to patients who underwent associated meniscectomy. Most common mechanism of injury was activity of sports in 20 patients. Postoperatively at 3 months, anterior drawer’s was 1+ in 6, 29 (85.2% patients had normal range of motion; 29 (85.29% patients had 5/5 quadriceps power (MRC grading 94% of them had 5/5 power at latest followup. No significant difference between outcomes of BPTB and Hamstrings graft. Functional outcome of our study were similar to the previously published studies.

    Objective:To demonstrate and evaluate a modified simple method about self-reduction of anterior shoulder dislocation for significance in the emergency room. Methods:TheBoss-Holzach-Matter method for self-reduction of anterior shoulder disloaction is described.Patients with an anterior shoulder dislocation were retrospectively analysed concerning age, gender, type of anterior shoulder dislocation, occurrence of associated fractures, time between injury and reduction, reduction time, and method of reduction with its respective success rate. Results:Eighty-six patients(52 men,34 women, mean age49 years) were treated fromJanuary 2010 toJune2014.The reduction time ranged between20 seconds and6 min(mean1.5 min). Subcoracoid type of shoulder dislocation was seen in72 cases(84%), subglenoid type in14 cases(16%).Associated factures were seen in20 cases, proportionally more often in subgleboid dislocations,12 at the greater tuberosity,6 at the inferior rim of the glenoid fossa and2 at both localizations.TheBoss-Holzach-Matter method was used in35 cases with a success rate of 71.5%; dieKocher method and traction/countertraction method with premedication were used in 14 cases and17 cases with success rates of64% and70%, respectively.All other cases and the failed primary attempts required hyponotic medication.All patients older than70(n=16) were not able to perform the self reducing procedure. Conclusion:The presentedBoss-Holzach-Matter method for reduction of anterior shoulder dislocation is a simple method without the need of anaesthesia, but cooperation from patients is crucial.The successful rate is comparable with other established methods.

    2011-01-01

    ObjectiveTo evaluate the safety of transverse iliosacral screw fixation of longitudinal sacral fracture.MethodsWe obtained CT scan data of the pelvis from 100 adults without any bony problems from September to December 2009. They were 52 males and 48 females, aged from 15 to 91 years (average, 43. 1 years) . We then reconstructed virtual three-dimensional models of the pelvis. The three-dimensional models were re-segmented through the sacral horizontal axis to obtain standard sagittal planes of the sacrum. To identify the safe zone for transverse screw fixation, we marked off the sacral margin on each sagittal plane. In simulation of the transverse screw ipsilateral fixation and transfixation, one single virtual cylindrical implant was inserted into the safe zone. The maximum diameter of the virtual cylindrical implant was measured.ResultsA 20. 0% rate of sacral variation was observed (80 normal versus 20 deformed morphological sacrums). In ipsilateral fixation, the average screw diameter of variant S2 (14. 92 ± 2.57 mm) >normal S2 ( 12. 37 ± 1.84 mm) ( P =0. 000) > normal S1 ( 11.87 ± 3.92 mm) ( P =0. 319 ) > variant S3 (9. 30 ± 2. 00 mm) ( P =0. 000). In transfixation, the average screw diameter of variant S2 ( 13.63 ± 2. 68 mm) > normalS2 (11.48 ±1.92mm) (P=0. 002) > normal S1(10. 40 ±4.05 mm) (P=0.033) >variant S3 (7.95 ± 2. 26 mm) ( P =0. 001 ) . The maximum screw diameter of normal S2 showed a slightly negative correlation with that of normal S1, but there was no correlation between the maximum screw diameter for each sacral vertebra and the acetabulum diameter. The normal male S2 was significantly larger than the female one ( P < 0.05), but there was no significant difference in S1 between genders ( P > 0.05) .ConclusionsIn most Chinese people, the posterior pelvic ring could be fixed with 2 iliosacral screws of 6. 5 mm in diameter simultaneously in horizontal direction, but care should be taken because the safety zone is quite

    Full Text Available INTRODUÇÃO: o tratamento das deformidades e más oclusões que incluem mordidas abertas anteriores foi uma das primeiras aplicações de miniplacas como forma de ancoragem ortodôntica. A implementação desse sistema de tratamento reduz o número de pacientes indicados para a cirurgia ortognática e simplifica muitos problemas. Nessa abordagem, os dentes posteriores são intruídos e a mandíbula sofre um giro no sentido anti-horário, diminuindo a altura facial inferior e projetando os pogônios de tecidos duro e mole. OBJETIVO: o presente artigo apresenta os fundamentos da mecânica ortodôntica para correção da mordida aberta anterior e os ilustra com uma série de casos clínicos.INTRODUCTION: The treatment of facial deformities and malocclusions, such as anterior open bite, was one of the first applications of miniplates for orthodontic anchorage. The use of this treatment system reduces the number of patients referred to orthognathic surgery and simplifies many problems. This approach applies intrusive forces to posterior teeth, and the mandible undergoes counterclockwise rotation, which decreases lower facial height and advances the projection of hard and soft tissue pogonions. OBJECTIVE: This study describes the principles of orthodontic mechanics in the correction of anterior open bite and illustrates these principles with a series of cases.

    Full Text Available Introduction The most frequent procedure in treatment of acute or chronic anterior cruciate ligament (ACL rupture is the so called bone-tendon-bone reconstruction. A transverse dislocated patella fracture is a rare complication of this procedure with an incidence of 0.23%-2.3%. In a five year period, (1998-2002, 407 arthroscopic reconstructions of the anterior cruciate ligaments were done at our Clinic, and there was only one case of patella fracture. Case report An 18-year-old female patient, a handball player, suffered an acute rupture of anterior cruciate ligament of the left knee, so arthroscopic bone-tendon-bone reconstruction of the anterior cruciate ligament was performed. After adequate skin incision, a bone graft was taken from the patella and upper part of trapezoid tibia, which was 25 mm long, 10 mm wide and 5 mm thick, together with a part of patellar ligament. After the remains of the anterior cruciate ligament had been arthroscopically removed, tunnels were made in tibia and femur and a graft was inserted and fixed with two metal interference screws. Knee stability was tested, and drainage was put in the knee joint. The wound was closed by layers. The quadriceps exercises and passive knee movements started immediately. Full range of movements was accomplished six weeks later when the patient started to walk with full weight-bearing on her operated leg. Three weeks later, (nine weeks after the operation, the patient has accidentally lost her balance and fell. A transverse, dislocated fracture of the left patella was diagnosed and osteosynthesis of the fractured patella with two Kirschner wires and a metallic loop was performed. Postoperatively, full range of movement was allowed. Six months later, the patient felt no pain, there was no swelling, full range of knee movement was achieved, while the Lachman Test was identical in both knees and the pivot shift test was negative. Discussion Fracture of patella after ACL reconstruction is

Treatment of anterior pituitary cells with this AC toxin resulted in an increase in cellular cAMP levels that was associated with accelerated exocytosis of growth hormone (GH), prolactin, adrenocorticotropic hormone (ACTH), and luteinizing hormone (LH). The kinetics of release of these hormones, however, were markedly different; GH and prolactin were rapidly released, while LH and ACTH secretion was more gradually elevated. Neither dopamine agonists nor somatostatin changes the ability of AC toxin to generate cAMP (up to 2 h). Low concentrations of AC toxin amplified the secretory response to hypophysiotrophic hormones. The authors conclude that bacterial AC toxin can rapidly elevate cAMP levels in anterior pituitary cells and that it is the response that explains the subsequent acceleration of hormone release.

    A 50-year-old Chinese man presented with rapidly progressive unilateral ophthalmoplegia and then an ipsilateral afferent pupil defect. CT and MRI revealed a mass centered in the anterior clinoid process causing bone destruction and showing high T1 and T2 signal intensity indicative of mucosal protein secretion. These imaging features suggested a mucocele, which may have resulted from sequestration of a clinoidal extension of the sphenoid sinus. The sphenoid sinus was opened via an image-guided endoscopic approach, and the lesion incised. There were no complications. The ophthalmoplegia and afferent pupil defect had completely resolved within 1 week of surgery. This is the eighth reported case of anterior clinoidal mucocele, a rare cause of ophthalmoplegia or optic neuropathy. Advances in endoscopic instrumentation, navigation systems, and intraoperative imaging have reduced the operative risk and made the endoscopic approach a feasible and safer alternative to open surgery for this condition.

    Full Text Available Although anterior cervical arthrodesis is an effective procedure for the treatment of cervical disorders, the method has some complications. Here, we describe this rare complication of cervical instrumentation with a literature review. A 23-year-old male patient was operated for a C6-C7 dislocation. At postoperative month 10, he presented with hemoptysis and dysphagia. Cervical roentgenograms showed anterior migrations of one broken screw and a plate-locking screw at the C6 corpus. One screw was missing. We concluded that the missing screw had perforated the esophagus and had been eliminated spontaneously through the gastrointestinal tract. No screw should migrate. Even loose screws should be noted in follow-up X-ray studies. If such findings are detected, a second operation for revision should be considered as soon as possible to prevent potentially fatal complications.

    Full Text Available The important role of the tooth size information is in making diagnosis and treatment plan of the cases with malocclusion. A lot of studies have been done in this aspect such as about tooth size with its variation, and also the ratio of maxillary to mandibular tooth size. The most famous tooth size analysis is Bolton analysis with his anterior ratio and overall ratio. Because the accordance of those ratio is not found in all orthodontic cases, some studies (Korbitz, Neff, Moyers and Steadman tried to relate the anterior ratio with the amount of overjet and overbite in orthodontic treatment. Those relationship was found strong, but there are also other analysis that should be considered in treating orthodontic cases.

    Severe vertical ridge deficiency in the anterior maxilla represents one of the most challenging scenarios in bone regeneration. Under ideal circumstances, guided bone regeneration in combination with soft tissue management has shown predictable esthetic and functional outcomes. Success largely relies on primary wound closure during and after the surgical procedure. Surgical sites present different challenges that need to be considered when designing the flap. The goal of this article is to propose a classification of flap designs that considers vestibular depth and scar formation around the periosteum when performing vertical ridge augmentation in the atrophic anterior maxilla. The four clinical conditions proposed under this classification are (1) shallow vestibule with healthy periosteum, (2) deep vestibule with healthy periosteum, (3) shallow vestibule with scarred periosteum, and (4) deep vestibule with scarred periosteum. The classification will allow clinicians to achieve tension-free closure and more predictable vertical bone gain.

    Full Text Available OBJECTIVE: The autors report a case of a traumatic rupture of the tibialis anterior tendon (TTA that was early diagnosed and treated in the emergency service. This is a rare clinical entity with few cases reported in the literature. CASE REPORT: A 66-year old female presented at the emergency service complaining about pain at the anterior aspect of her ankle and inability to walk normally, after a fall. Physical examination revealed clinical signs for TTA rupture, which was later confirmed by ultrasound. Surgical treatment was performed immediately â€" the tendon was anchored into the medial cuneiform with a soft tissue-to-bone anchor. The follow-up revealed good functional result. CONCLUSION: Physical examination and a high index of suspicion are important when facing a patient who had sustained an ankle trauma. The TTA rupture is a diagnosis to consider because unrecognized ruptures led to important functional deficits and poor functional results.

    The serratus anterior plane block has been described for analgesia of the hemithorax. This study was conducted to determine the spread of injectate and investigate the anatomical basis of the block. Ultrasound-guided serratus anterior plane block was performed on six soft-fix embalmed cadavers. All cadavers received bilateral injections, on one side performed with 20 ml latex and on the other with 20 ml methylene blue. Subsequent dissection explored the extent of spread and nerve involvement. Photographs were taken throughout dissection. The intercostal nerves were involved on three occasions with dye, but not with latex. The lateral cutaneous branches of the intercostal nerve contained dye and latex on all occasions. The serratus plane block appears to be mediated through blockade of the lateral cutaneous branches of the intercostal nerves. Anatomically, serratus plane block does not appear to be equivalent to paravertebral block for rib fracture analgesia. PMID:27440171

    Full Text Available Genetic diseases are congenital or acquired hereditary diseases that result from structural/functional disorders of the human genome. Today, the genetic factors that play a role in many diseases are being highlighted with the rapid progress in the field of genetics science. It becomes increasingly important that physicians from all disciplines have knowledge about the basic principles of genetics, patterns of inheritance, etc., so that they can follow the new developments. In genetic eye diseases, ophthalmologists should know the basic clinical and recently rapidly developing genetic characteristics of these diseases in order to properly approach the diagnosis and treatment and to provide genetic counseling. In this paper, anterior segment eye diseases of genetic origin are reviewed, and aniridia, anterior segment dysgenesis, glaucoma, corneal dystrophies, cataract, ectopia lentis, myopia, and other refractive errors are covered.

    The aim of this article is to discuss the different types of monolithic ceramic crowns that can be placed on anterior teeth with existing shoulder preparations. Anterior crowns were indicated for the teeth 12 to 22 in the present case. The patient, a 65-year-old male, had received all-ceramic crowns 20 years earlier, which had started to develop cracks and palatal fractures over the last few years. The patient's teeth were prepared and four sets of crowns were fabricated using different monolithic ceramic materials: IPS e.max CAD, Cerec Blocs C In, VITABLOCS Real Life, and ENAMIC. Both shade characterization and crystallization firing were performed on the monolithic lithium disilicate glass ceramic crowns. The silicate ceramic crowns received glaze firing alone. The crowns made of hybrid ceramic (ENAMIC) were treated with a polymer sealant. PMID:24555406

    2013-05-01

    Meningiomas are the most common form of primary intracranial tumors. If the anterior visual pathways are affected clinical visual compromise, visual field defects, oculomotor nerve disturbances or propotosis are predominant. Meningiomas of the anterior visual pathway remain therapeutically challenging due to the direct anatomical relationship to the circulus arteriosus cerebri, the cavernous sinus and cranial nerves. The therapy of choice is microsurgical resection. In many cases a curative approach can be achieved with modern surgical techniques and simultaneously maintaining patient quality of life. Problematic are cases in which resection would be associated with the risk of clinical impairment and in these cases radiotherapy is an important therapeutic option. In cases involving complex invasiveness an interdisciplinary treatment to control local clinical symptoms is favored. PMID:23604251

    Full Text Available One third of patients with antiepileptic-resistant temporal lobe epilepsy (TLE will have to undergo surgery for a better seizure control. Anterior temporal lobectomy (ATL is done for mesial temporal sclerosis that is the most common histopathological lesion associated with TLE. Psychiatric manifestations following ATL are not uncommon with depressive symptoms more common with left ATL and manic symptoms following right ATL. Mr. A is a 42-year-old left cerebral dominant (Confirmed by WADA test male with no past history of psychiatric illness who had undergone anterior temporal lobectomy with amygdalohippocampectomy. He started having manic episodes post operatively which subsided with antipsychotics. He had multiple such episodes over the next 13 years with minimal inter episodic symptoms. This is a rare instance of manic symptoms following left-sided ATL that emphasizes the need for better understanding of the cerebral laterality of affective symptoms.

    Full Text Available No- or minimal-preparation veneers associated with enamel preservation offer predictable results in esthetic dentistry; indirect additive anterior composite restorations represent a quick, minimally invasive, inexpensive, and repairable option for a smile enhancement treatment plan. Current laboratory techniques associated with a strict clinical protocol satisfy patients’ restorative and esthetic needs. The case report presented describes minimal invasive treatment of four upper incisors with laminate nanohybrid resin composite veneers. A step-by-step protocol is proposed for diagnostic evaluation, mock-up fabrication and trial, teeth preparation and impression, and adhesive cementation. The resolution of initial esthetic issues, patient satisfaction, and nice integration of indirect restorations confirmed the success of this anterior dentition rehabilitation.

  5. Effect of bone loss in anterior shoulder instability

    Garcia, Grant H; Liu, Joseph N; Dines, David M; Dines, Joshua S

    2015-01-01

    Anterior shoulder instability with bone loss can be a difficult problem to treat. It usually involves a component of either glenoid deficiency or a Hill-Sachs lesion. Recent data shows that soft tissue procedures alone are typically not adequate to provide stability to the shoulder. As such, numerous surgical procedures have been described to directly address these bony deficits. For glenoid defects, coracoid transfer and iliac crest bone block procedures are popular and effective. For humeral head defects, both remplissage and osteochondral allografts have decreased the rates of recurrent instability. Our review provides an overview of current literature addressing these treatment options and others for addressing bone loss complicating anterior glenohumeral instability. PMID:26085984

  6. MR for assessing anterior cruciate ligament reconstructions by tendon grafts

    International Nuclear Information System (INIS)

    150 patients were examined via magnetic resonance (MR) after anterior cruciate (ACL) ligament reconstruction (76 patellar tendon grafts, 53 semitendinosous tendon grafts and 21 sutures). The results of MR were compared with clinical tests (Lachman, pivot-shift and anterior drawer test), in 2 cases with the operative findings, and in one case with arthroscopy findings. In 91% of patients with a clinically stable knee we found a continuous low-intensity ligamental structure. 10 patients were examined twice or more between 8 days and 6 months after surgery. Ligamental structures of low signal intensity did not significantly change their MR characteristics. MR is a valuable noninvasive method for evaluating ligament reconstructions. (orig./GDG)

    1992-01-01

    Three patients developed signs of a unilateral cervical cord lesion 6 to 36 h after the acute onset of severe cervico-brachial pain. The neurological deficit progressed over 6 to 18 h. On the painful side a central Horner's syndrome, a hemiparesis with plegia of the hand, and a slight pallhypaesthesia were found. On the opposite side thermhypaesthesia and hypalgesia were noted with a level at the dermatome C5 or C6. T2-weighted MR images revealed in one patient a small area of increased signal intensity restricted to one half of the cervical cord, and electromyography in another patient showed after 6 months evidence of segmental chronic denervation. Both abnormalities were found at the clinically expected level. The findings are consistent with a small infarction of the cervical cord in the perfusion territory of a central (sulco-commissural) artery, a duplicated anterior spinal artery or an anterior spinal branch of the vertebral artery.

Objectives: The current study aimed to compare RV function in patients with inferior and anterior MI. Patients and Methods: During the study period, 60 patients consecutively presented to the Emergency Department with chest pain were divided into two groups based on their electrocardiographic findings. Accordingly, 25 patients had inferior MI (IMI group and 35 ones had anterior MI (AMI group. Echocardiography was performed 48 hours after starting the standard therapy. Conventional echocardiographic parameters and Tissue Doppler Imaging (TDI measurements were acquired from the standard views. Student t-test and the chi-square test were respectively used for comparisons of the normally distributed continuous and categorical variables in the two groups. Besides, P < 0.05 was considered to be statistically significant.

    Full Text Available A luxação glenoumeral anterior bilateral é uma ocorrência rara. Apresentamos um caso de luxação glenoumeral anterior bilateral com origem após uma queda da própria altura. O interesse desta publicação reside no fato de se tratar de uma raridade clínica com poucos casos descritos na literatura. Paciente do sexo feminino com 89 anos recorre ao serviço de urgência (SU após queda referindo dor intensa e incapacidade de mobilização de ambos os ombros. Ao exame objetivo apresentava sinais clínicos suspeitos de luxação glenoumeral anterior bilateral confirmados por radiografia. Ambas as luxações foram reduzidas no SU pela técnica de Milch modificada, com sucesso. Quando existe uma força simétrica e síncrona sobre os ombros e estes se apresentarem dolorosos e com limite funcional significativo, a suspeita de luxação glenoumeral bilateral, embora rara, é um diagnóstico diferencial a ter em conta.Bilateral anterior glenohumeral dislocation is a rare occurrence. We present a case of bilateral anterior glenohumeral dislocation caused by a fall. The interest in publishing this case is that this is a clinical rarity with few cases reported in the literature. An 89-year-old female patient was brought to the emergency department after a fall, complaining of intense pain in both shoulders and inability to move them. Objective examination showed clinical signs giving the suspicion of bilateral anterior glenohumeral dislocation, which was confirmed by x-ray imaging. Both dislocations were successfully reduced in the emergency department using the modified Milch technique. When a synchronous and symmetrical force has acted on both shoulders and these are painful with significant functional limitation, the suspicion of bilateral glenohumeral dislocation is a differential diagnosis to be considered, even though it is rare.

  12. Anterior knee pain: an update of physical therapy.

    Science.gov (United States)

    Werner, Suzanne

    2014-10-01

    Anterior knee pain is one of the most common knee problems in physically active individuals. The reason for anterior knee pain has been suggested to be multifactorial with patella abnormalities or extensor mechanism disorder leading to patellar malalignment during flexion and extension of the knee joint. Some patients complain mostly of non-specific knee pain, while others report patellar instability problems. The patients present with a variety of symptoms and clinical findings, meaning that a thorough clinical examination is the key for optimal treatment. Weakness of the quadriceps muscle, especially during eccentric contractions, is usually present in the majority of anterior knee pain patients. However, irrespective of whether pain or instability is the major problem, hypotrophy and reduced activity of the vastus medialis are often found, which result in an imbalance between vastus medialis and vastus lateralis. This imbalance needs to be corrected before quadriceps exercises are started. The non-operative rehabilitation protocol should be divided into different phases based on the patient's progress. The goal of the first phase is to reduce pain and swelling, improve the balance between vastus medialis and vastus lateralis, restore normal gait, and decrease loading of the patello-femoral joint. The second phase should include improvement of postural control and coordination of the lower extremity, increase of quadriceps strength and when needed hip muscle strength, and restore good knee function. The patient should be encouraged to return to or to start with a suitable regular physical exercise. Therefore, the third phase should include functional exercises. Towards the end of the treatment, single-leg functional tests and functional knee scores should be used for evaluating clinical outcome. A non-operative treatment of patients with anterior knee pain should be tried for at least 3 months before considering other treatment options.

    2011-10-01

    Indentation and histological analysis of the porcine iris were done to assess the relative stiffness of the anterior (stroma) and posterior (dilator and sphincter) layers. The dimensions of the constituent structures were documented histologically by staining with a monoclonal anti-human α-smooth muscle actin antibody to determine the location of the stroma, sphincter, and dilator. Intact porcine irides (4-8 h post-mortem) were bisected into two equal C-shaped halves to indent both surfaces. Indentation experiments were performed using a 1 mm cylindrical indenter tip. The load-displacement curve for each experiment was used to estimate effective instantaneous and equilibrium moduli for the anterior and posterior surfaces of the tissue. A total of 18 irides (9 pairs) with 3-5 indentations per iris surface was performed. The average thickness of the samples was 550 μm; the indentation depth was limited to 60-100 μm depending on the thickness of the sample at each point. Posterior surface indentation gave larger forces than anterior, with the resulting instantaneous modulus of 6.0 ± 0.6 kPa versus 4.0 ± 0.5 kPa (mean ± 95% CI, n = 45, p poroelasticity, we conclude that the posterior components of the iris - dilator, pigment epithelium, and sphincter - are on average stiffer than the stroma and anterior border layer.

Materials and Methods: Two hundred eighty-four eyes of 252 patients followed up in our cornea clinic who underwent DALK using Anwar’s big-bubble technique with healthy Descemet’s membrane and endothelium were included in this study. Intraoperative and postoperative complications as well as the management and treatment of these complications were evaluated. Results: Big bubble was created in 220 (77.5% eyes of 284 eyes, and lamellar dissection was performed in 64 (22.5% eyes. Perforation occurred during trephination in 4 eyes, and the procedure was accomplished by penetrating keratoplasty (PK. Intraoperative microperforation occurred in 44 eyes. Perforation enlarged in 4 eyes and PK was performed. Operation was continued in 40 eyes with air injection into the anterior chamber. In postopertive follow-up period, double anterior chamber (DAC occurred in 32 of 40 eyes. DAC spontaneously regressed in 8 eyes, and air was given into the anterior chamber with a second surgical intervention in 24 eyes. DAC improved in 20 eyes. Four eyes underwent PK. Fungal keratitis evolved at the interface in one eye, because of no healing during the follow-up period, this eye underwent PK under antifungal therapy. Eyes with interface haze and Descemet’s membrane folds were followed. Conclusion: DALK is a difficult technique with a steep learning curve. In addition to the complications seen in PK, specific complications can occur in lamellar surgery. (Turk J Ophthalmol 2014; 44: 337-40

    2008-01-01

    Full Text Available AbstractBackground and Purpose: Anterior shoulder dislocation is the most common major joint dislocation. In most cases, this dislocation is being relocated in emergency departments. Routinely, pre and post reduction radiographs are performed. This study was done to determine the necessity of radiographs in the emergency department for management of patients with suspected anterior shoulder dislocation.Materials and Methods: In this case series study, 116 patients suspected of anterior shoulder dislocation were referred to Hazrat Rasoul Akram and Haftome Tir Hospitals emergency departments in Tehran, and were investigated for a one year period. The emergency physicians evaluated and documented the possibility of dislocation or relocation, before obtaining radiographs. Outcome measures were the assessment of joint positions on the x-rays by an orthopedic surgeon.Results: 84 cases (72% were male and 32 cases (28% were female. Mean age of the patients was 31.5±8.5 yrs. Thirty (30 patients had recurrent dislocations without traumatic mechanism (group 1 and eighty six (86 patients had no prior dislocation or a blunt mechanism of injury (group 2. The accuracy of the emergency physician’s assessment in dislocations was 100% in group 1 and 98% in group 2. False assessments occurred only in patients with fractures. There is no significant difference between emergency physicians and orthopedic surgeons in the assessment of dislocations and relocations, when the emergency physicians did accuralty diagnose them.Conclusion: Our study showed that the physicians are highly accurate in clinical determination of anterior shoulder dislocation and relocation. Pre-reduction films should be obtained when the mechanism of injury is trauma. Post-reduction films should be obtained in fracture-dislocations or when the physicians are uncertain of correct relocation.

    Full Text Available Background: Although ultrasound (US has a wide range of applications in orthopedic diagnostics, sonographic evaluation of traumatic anterior cruciate ligament (ACL insufficiency is still inadequate. There is a growing need for diagnostic tests that allow for simple and reliable assessment of ACL instability. This investigation aims to evaluate feasibility of sonographic technique for diagnosing complete ACL insufficiency. Materials and Methods: Eighty three consecutive patients suspected of ACL injury were examined with sonographic, dynamic test of anterior instability. The translation of the intercondylar eminence against the patellar tendon was measured in the injured and opposite (injured knee. Subsequent magnetic resonance imaging was performed on all patients. Forty-seven of them underwent a further arthroscopy. Five patients have been examined for the 2 nd time to evaluate interclass and intraclass agreement and bias. Results: Complete ACL insufficiency has been confirmed in 37 patients. In those individuals, the total anterior knee translation and the difference between two joints (side-to-side difference were significantly increased (8.67 mm standard deviation [SD] 2.65 mm in the affected knee versus 2.88 mm SD 1.26 mm in uninjured joint; P < 0.001. Based on a threshold of 2.0 mm for the side-to-side difference and 5.0 mm for the absolute translation, the sonographic test was found to have a sensitivity and specificity of 91.9% and 95.6%, respectively. Conclusions: The present technique supports the clinician with additional fast and noninvasive diagnostic procedure that can facilitate the evaluation of anterior knee instability.

    The new millennium has witnessed the emergence of minimally invasive, non-posterior based surgery of the lumbar spine, in particular via lateral based methodologies to discectomy and fusion. In contrast, and perhaps for a variety of reasons, anterior motion preservation (non-fusion) technologies are playing a comparatively lesser, though incompletely defined, role at present. Lateral based motion preservation technologies await definition of their eventual role in the armamentarium of minimal...

    Accurate metrology of the anterior chamber of the eye is useful for a number of diagnostic and clinical applications. In particular, accurate corneal topography and corneal thickness data is desirable for fitting contact lenses, screening for diseases and monitoring corneal changes. Anterior OCT systems can be used to measure anterior chamber surfaces, however accurate curvature measurements for single point scanning systems are known to be very sensitive to patient movement. To overcome this problem we have developed a parallel 3D spectral metrology system that captures simultaneous A-scans on a 2D lateral grid. This approach enables estimates of the elevation and curvature of anterior and posterior corneal surfaces that are robust to sample movement. Furthermore, multiple simultaneous surface measurements greatly improve the ability to register consecutive frames and enable aggregate measurements over a finer lateral grid. A key element of our approach has been to exploit standard low cost optical components including lenslet arrays and a 2D sensor to provide a path towards low cost implementation. We demonstrate first prototypes based on 6 Mpixel sensor using a 250 μm pitch lenslet array with 300 sample beams to achieve an RMS elevation accuracy of 1μm with 95 dB sensitivity and a 7.0 mm range. Initial tests on Porcine eyes, model eyes and calibration spheres demonstrate the validity of the concept. With the next iteration of designs we expect to be able to achieve over 1000 simultaneous A-scans in excess of 75 frames per second.

    Full Text Available Septic arthritis of the knee is a rare complication after arthroscopic anterior cruciate ligament reconstruction, and the most appropriate treatment is unclear. All case series reported so far have been retrospective, and case numbers of septic arthritis have ranged from 4 to 11. From a consecutive case series of 1,283 patients who underwent arthroscopic anterior cruciate ligament reconstruction between January 1997 and May 2008, we report on 3 patients (0.23% with post-operative septic arthritis. All patients had acute infection (≤ 2 weeks, bacterial cultures showed Staphylococcus species in 2 patients, while the bacterial culture was negative in the third. All of them underwent immediate arthroscopic debridement and lavage with continuous irrigation, as well as antibiotic treatment. The results were evaluated with physical and radiographic examination, functional testing, KT-2000, Lysholm and Tegner scales. The infection was successfully eradicated without further surgical treatment and the ligament graft was retained in all patients. Follow-up, at an average of 33 months, revealed that the patients had full symmetric knee range of motion and no effusion. The average Lysholm score was 91 points. In the patient with a lower subjective score, radiographs demonstrated patellofemoral joint-space narrowing, which is most probably in correlation with his anterior knee pain problems and lower activity level. The 134 N KT-2000 arthrometer side-to-side differences averaged 13 mm. Their performance in the single-legged hop test gave excellent results. The goals of treatment for septic arthritis after anterior cruciate ligament reconstruction are, primarily, to protect the articular cartilage and, secondly, to protect the graft. Through early diagnosis and prompt treatment, the infection can be successfully eradicated, with stability of the knee and full range of motion achieved.

    The anterior cruciate ligament (ACL) plays an important role in controlling knee joint stability, not only by limiting tibial anterior translation but also by controlling knee axial rotation. The aim of ACL reconstruction is to reduce excessive anterior joint laxity, hoping to restore normal tibiofemoral kinematics including knee axial rotation. The purpose of this study was to investigate the relationship between static anterior instability and tibial rotation during several activities in an anterior cruciate ligament reconstructed knee. Seven patients with unilateral ACL injury performed plain walking, running, landing and side step cutting tasks after ACL reconstruction with a mean follow-up of 14 months. The kinematic data for the 4 motions was measured using a motion analysis system and the point cluster technique. The evaluation period was defined to be from the first contact to removal of the tested leg from the ground. Maximum tibial internal rotation during tasks was calculated using the point cluster technique (PCT). Passive anterior tibial translation was measured using a KT-1000 arthrometer. Regression analysis was used to determine the correlation of the maximum internal rotation with the side-to-side difference of static anterior tibial translation measured using a KT-1000 arthrometer. During side step cutting maneuvers, maximum tibial internal rotation significantly showed negative correlation with static anterior tibial translation (pknee rotation kinematics. The normal anterior tibial translation obtained by ACL reconstruction is thought to be the key factor in successful restoration of normal knee kinematics. PMID:23925154

Anterior uveitis may be caused by a variety of etiologies, including infectious, noninfectious, and masquerade diseases. The short-term and long-term treatment of uveitis should include the evaluation of location, duration, pathology, and laterality, in addition to presenting signs and symptoms of the disease. A complete review of systems, thorough examination, and laboratory testing, may assist the practitioner in narrowing the list of possible causes for the uveitis. This is imperative as once a list of diagnoses has been made, a targeted approach to treatment can be pursued. Keywords: anterior uveitis, iritis, inflammation

    Full Text Available The biologic width (BW includes attached epithelial cells and connective tissue attachment complex being very important in the periodontal health during prosthetic treatments as invading this zone can cause bone resorption and gingival recession. The present study investigated biologic width values in the normal periodontium in anterior and posterior teeth. 30 patients that referred from restorative department to periodontics department of Tehran University of medical sciences who need crown lengthening procedure on their teeth with no history of orthodontic, prosthodontic and periodontal treatment were randomly enrolled in this cross-sectional trial. Sulcus depths (SD as well as the distance between free gingival margin and the bone crest (FB of anterior and posterior teeth were measured by UNC-15 probe and compared. periodontium thickness was also assessed. The data were subjected to Student t test. Mean BW in the 43 anterior and 47 posterior teeth was measured and not significantly different (1.4651±0.39 mm vs. 1.6312±0.49 mm was observed; however, BW was significantly more in the teeth with thick periodontium compared to those with thin periodontium (1.703±0.5 vs. 1.408±0.35; P=0.002. BW not only is different in individuals but also could be dissimilar in different teeth and should be calculated independently prior to restorative treatments.

    Fat is not just used by the body as bulk tissue. In addition to its role in storing energy and regulating hormone action, fat is used in some parts of the body for its mechanical properties. The anatomy of anterior knee fat is more complex than it appears at first sight and is capable of withstanding considerable compressive and shear stress. Specific lesions occur when such mechanical stress exceeds the physiological limits and are yet little known. Superficial fat can be the site of either acute injury by closed degloving called the Morel-Lavallée lesion or chronic injury, when subject to repeat excessive shear forces, due to more complex and less well-defined disruptions that result in pseudo-bursitis. There are three main anterior, intracapsular and extrasynovial fat pads in the knee joint, which are the infrapatellar fat pad (IFP) or Hoffa's fat pad, the quadriceps fat pad and the prefemoral fat pad. The IFP plays an important role as a mechanical shock absorber and guides the patella tendon and even the patella itself during flexion-extension movements. In response to repeated excessive stress, an inflammatory reaction and swelling of the IFP is first observed, followed by a fibrotic reaction with metaplastic transformation into fibrous, cartilaginous or bone tissue. More rarely, the two other deep fat pads (quadriceps and prefemoral) can, if subject to repeated stress, undergo similar restructuring inflammatory reactions with metaplasia resulting in tissue hardening, anterior pain and partial loss of function.

    2013-04-01

    Full Text Available Introduction: Anterior dislocation of shoulder is commonest dislocation one encounters in day to day Orthopaedic practice. But bilateral shoulder dislocations are relatively uncommon frequently posterior and secondary to violent muscle contraction. Simultaneous bilateral anterior dislocations of shoulder following trauma is rare occurrence. Case Report: 35 year old male presented to emergency department with history fall by tripping on a stone (fall on outstretched hand. He complained of pain and difficulty in moving both the shoulders. On clinical examination, patient’s both upper limbs were abducted and externally rotated. Bilaterally shoulder contour was lost with flattening. Other classical signs of shoulder dislocation viz, Bryants test, Callway sign, Hamilton’s ruler test were positive. Diagnosis was confirmed on X rays. Both shoulders were reduced in emergency operation theater under general anaesthesia by Kocher’s method and were immobilised in sling. Conclusion: Though bilateral shoulder dislocations are commonly posterior, usually either secondary to convulsions or electric shock, anterior dislocation has to be kept in mind , especially in post traumatic injuries. This bilateral dislocation also presents with practical problems immobilization and day to day care of patients. Keywords: Simultaneous, bilateral, shoulder dislocation, traumatic.

    Optical coherence tomography (OCT) images can provide quantitative measurements of the eye's entire anterior segment. A new technique founded on a newly proposed level set-based shape prior segmentation model has been developed for automatic segmentation of the cornea's anterior and posterior boundaries. This technique comprises three major steps: removal of regions containing irrelevant structures and artifacts, estimation of the cornea's location using a thresholding technique, and application of the new level set-based shape prior segmentation model to improve segmentation. The performance of our technique is compared to previously developed methods for analysis of the cornea in 33 OCT images of normal eyes, whereby manual annotations are used as a reference standard. The new technique achieves much improved concordance than previous methods, with a mean Dice's similarity coefficient of >0.92. This demonstrates the technique's potential to provide accurate and reliable measurements of the anterior segment geometry, which is important for many applications, including the construction of representative numerical simulations of the eye's mechanical behavior.

  20. Activation of anterior insula during self-reflection.

    Directory of Open Access Journals (Sweden)

    Gemma Modinos

    Full Text Available BACKGROUND: Functional neuroimaging studies have suggested activation of midline frontoparietal brain regions to be at the core of self-related processes. However, although some studies reported involvement of the insula, little attention has been paid to this region as forming part of the "self"-network. METHODOLOGY/PRINCIPAL FINDINGS: Using functional magnetic resonance imaging (fMRI, we aimed at replicating and extending previous studies by scanning subjects whilst reflecting upon their own personal qualities as compared to those of an acquaintance. A third condition with statements about general knowledge was used to control for attention, semantic processing and decision making processes. The results showed a significant effect of task in brain activity, consistent with previous findings, by which both person conditions recruited a common set of medial prefrontal and posterior regions, yet significant differences between self and other were found in the medial prefrontal cortex (MPFC and the anterior cingulate cortex (ACC. Notably, significant neural activation in the left anterior insula was observed as uniquely associated with self-reflection. CONCLUSIONS/SIGNIFICANCE: The results provide further evidence for the specific recruitment of anterior MPFC and ACC regions for self-related processing, and highlight a role for the insula in self-reflection. As the insula is closely connected with ascending internal body signals, this may indicate that the accumulation of changes in affective states that might be implied in self-processing may contribute to our sense of self.
