    Full Text Available A base do tratamento cirúrgico da Síndrome do Desfiladeiro Torácico (SDT é a ressecção da primeira costela, podendo associar-se à escalenectomia ou ainda à ressecção de costela cervical. Esta última é feita tradicionalmente por meio de um acesso supraclavicular ou mesmo axilar, o qual é tecnicamente mais trabalhoso. Pode ser realizada também por meio de acesso paraescapular. Embora tecnicamente atrativa e associada à menor invasividade e maior segurança, com ótimo resultado estético, a ressecção da primeira costela torácica, por intermédio de cirurgia videoassistida transaxilar ou pela técnica videotoracoscópica, é pouco relatada na literatura, e nenhuma referência foi encontrada sobre ressecção de costela cervical mediante essa técnica. Neste artigo, apresentamos essa inovação cirúrgica realizada com sucesso para ressecção de costela cervical em duas pacientes.The basis of Thoracic Outlet Syndrome (TOS surgical treatment is the first rib resection and may be associated with scalenectomy or cervical rib resection. The latter is traditionally done through a supraclavicular or axillary access, which is the most technically challenging. It can also be achieved through parascapular access. Although technically attractive and associated with less invasiveness and increased security, with excellent aesthetic results, the first thoracic rib resection via video-assisted transaxillary surgery or videothoracoscopic technique is seldom reported in the literature, and no reference was found on cervical rib resection through this technique. In this article, we introduced this innovation successfully performed for surgical cervical rib resection in two patients.

    Full Text Available The Thoracic Outlet is bounded by the first thoracic Vertebra posteriorly, superior border of manubrium sternum anteriorly, and the first rib and costal cartilage laterally. Thoracic outlet syndrome is a general term for a number of disorders producing neurovascular compression over this area. Cervical Rib is a congenital bony abnormality in which an extra rib is present superior to first rib is attached to C7 vertebra. Of the many factors which can cause neurovascular compression, 30% of the cases is due to bony abnormalities. Cervical rib is one of the important bony factors which lead to thoracic outlet syndrome due to the displacement and compression of the neurovascular structures while crossing the thoracic outlet to the upper limb. In the collection of bones in the Institute of Anatomy Madras medical college, cervical ribs were present bilaterally in two specimens. The present paper will definite be useful to clinicians while dealing with thoracic outlet syndrome.

  3. Case report: Short rib polydactyly syndrome - type 2 (Majewski syndrome)

    International Nuclear Information System (INIS)

    Short rib polydactyly syndrome (SRPS) type 2 (Majewski syndrome) is a rare inherited, autosomal recessive, lethal skeletal dysplasia characterized by horizontally located short ribs, pre- and postaxial polysyndactyly, and micromelia, with characteristic short ovoid tibiae. There may or may not be visceral involvement. We report a case of SRPS type 2 that was diagnosed by antenatal USG at 28 weeks of gestation; the diagnosis was subsequently confirmed by postnatal radiography, fetal autopsy, and histopathology

    Slipping rib syndrome is an overlooked cause of persistent abdominal or chest pain. The etiology of this syndrome is not well understood, but the characteristic pain is from hypermobility of the false ribs. Although it is a diagnosis of exclusion, misdiagnosis may lead to an excessive workup. A simple clinical examination via the hooking maneuver is the most significant feature of its diagnosis. We describe the case of a 41-year-old woman with slipping rib syndrome. PMID:26528703

    A stillborn baby boy had findings of severe constitutional dwarfism with short limbs, short ribs, and polydactyly that were consistent with Naumoff (type III) short-rib polydactyly syndrome. He also had additional congenital anomalies, including cleft palate, notching of the upper lip, small tongue with accessory sublingual tissue. These oral and pharyngeal anomalies were consistent with Mohr (type II) oral-facial-digital syndrome. We suggest the stillborn infant represented a compound of Naumoff short-rib polydactyly syndrome (SRPS-III) and Mohr oral-facial-digital syndrome (OFDS-II). (orig.)

  6. Extraordinary incidence of cervical ribs indicates vulnerable condition in Late Pleistocene mammoths

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available The number of cervical vertebrae in mammals is highly conserved at seven. We have shown that changes of this number are selected against due to a coupling with major congenital abnormalities (pleiotropic effects. Here we show that the incidence of abnormal cervical vertebral numbers in Late Pleistocene mammoths from the North Sea is high (33.3% and approximately 10 times higher than that of extant elephants (3.6%. Abnormal numbers were due to the presence of large cervical ribs on the seventh vertebra, which we deduced from the presence of rib articulation facets on sixth (posterior side and seventh (anterior side cervical vertebrae. The incidence of abnormal cervical vertebral numbers in mammoths appears to be much higher than in other mammalian species, apart from exceptional sloths, manatees and dugongs and indicates a vulnerable condition. We argue that the increased incidence of cervical ribs in mammoths is probably caused by inbreeding and adverse conditions that impact early pregnancies in declining populations close to extinction in the Late Pleistocene.

    A 12-week-old boy with Jeune syndrome (asphyxiating thoracic dystrophy) was referred to the orthopaedic unit with progressive respiratory failure, recurrent respiratory tract infections, and recurrent admissions to the intensive care unit for ventilatory support. His chest x-ray revealed a small and narrow thoracic cage with short broad ribs and abnormal costal cartilages. His chest expansion was impaired by the short, horizontally positioned ribs resulting in alveolar hypoventilation. Without surgical intervention to expand his thoracic cage, he would die of respiratory failure.

    DiGeorge syndrome results from defect in the development of the third and fourth pharyngeal pouches, and is characterized by conotruncal heart defects, aplasia or hypoplasia of thymus and parathyroid glands resulting in immune deficiency and hypocalcemia. Other associated abnormalities include renal, thyroid and diaphragmatic defects, oral clefting, etc. Etiologically, it is heterogeneous, with a microdeletion of 22q11 present in over 80% of cases. Our patient was born following a pregnancy complicated by insulin dependent gestational diabetes. There was truncus arteriosus type 2, absense of thymic shadow on CXR with severe deficiency of T cell function, and persistent hypocalcemia with low parathormone. Right kidney was absent. Dysplastic ribs including fused and bifid ribs were noted. Hypoplastic vertebrae and hemivertebrae were present through thoracic and lumbar regions. Chromosome analysis was normal, and metaphase FISH analysis with probe N25 representing locus D22S75 did not show any deletion of 22q11.2. The skeletal findings similar to these have not been previously reported in association with DiGeorge syndrome to our knowledge. Vertebral and rib abnormalities are known to occur with pregestational maternal diabetes. Maternal diabetes has also been suggested to be a possible etiology in a very small proportion of DiGeorge syndrome cases. It is possible that these findings occured together on account of gestational maternal diabetes in our case.

    Glucocorticoid (GC) excess, including Cushing's syndrome, is a common cause of secondary osteoporosis. Thirty to fifty percent of Cushing's syndrome patients experience non-traumatic fractures, which is often the presenting manifestation of Cushing's syndrome. However, there have been rare cases of Cushing's syndrome diagnosed only based upon bone manifestations. We describe a case of Cushing's syndrome that was diagnosed in a 44-year-old woman who initially visited our hospital due to multiple non-traumatic rib fractures. She did not exhibit any other manifestations of Cushing's syndrome such as moon face, buffalo hump or abdominal striae. Initially, we evaluated her for bone metastases from a cancer of unknown origin, but there was no evidence of metastatic cancer. Instead, we found a left adrenal incidentaloma. As a result of the hormone study, she was diagnosed as having Cushing's syndrome. Interestingly, her bony manifestation of Cushing's syndrome, which was evident in the bone scan and bone mineral densitometry, completely recovered after a left adrenalectomy. Therefore, the possibility of Cushing's syndrome as a cause of secondary osteoporosis should be considered in young patients with non-traumatic multiple fractures, with or without any other typical features of Cushing's syndrome.

  10. Perinatally lethal short rib-polydactyly syndromes. Pt. 1

    International Nuclear Information System (INIS)

    Thirteen newborns with lethal short rib-polydactyly (SRP) have been reviewed, 11 with SRP type 3 (Verma-Naumoff) and 2 with SRP tye 2 (Majewski). In the former group there were three sets of siblings. The excess of males with SRP type III (Verma-Naumoff) is confirmed in this present study. A high frequency of phenotypic females including sex-reversed constitutional males with SRP type 1 (Saldino-Noonan) is in marked contrast to these findings in SRP type 3. Possible hypotheses include variable expressivity in non-Majewski short rib-polydactyly syndromes with sex-reversed and constitutional female cases tending to show more severe phenotypic expression both in terms of major anomalies and skeletal dysplastic effects.

    2012-05-01

    Treacher Collins syndrome is a congenital syndrome with characteristic craniofacial malformations, which are well described in the literature. However, the presence of cervical spine dysmorphology in this syndrome has been minimally described. This study reviews cervical spine radiographs of 40 patients with Treacher Collins syndrome. In this sample, 7 of 40 patients displayed cervical spine anomalies, with 3 of these patients displaying multiple cervical spine anomalies. The patterns of spinal anomalies were variable, suggesting that the underlying genetic mutation has variable expressivity in cervical spine development as it does elsewhere in the craniofacial skeleton.

    Full Text Available Abstract Background Cronkhite-Canada syndrome (CCS is a rare multiple gastrointestinal polyposis. Up till now, many complications of CCS have been reported in the literature, but rib fracture is not included. Case Presentation We report a case of a 58-year-old man who was admitted to our hospital with a 6-month history of frequent diarrhea, intermittent hematochezia and a weight loss of 13 kg. On admission, physical examination revealed alopecia of the scalp, hyperpigmentation of the hands and soles, and dystrophy of the fingernails. Laboratory data revealed hypocalcaemia and hypoproteinemia. Esophagogastroduodenoscopy, video capsule endoscopy and colonoscopy revealed various sizes of generalized gastrointestinal polyps. Histological examination of the biopsy specimens obtained from the stomach and the colon showed adenomatous polyp and inflammatory polyp respectively. Thus, a diagnosis of CCS was made. After treatment with corticosteroids for 24 days and nutritional support for two months, his clinical condition improved. Two months later, he was admitted to our hospital for the second time with frequent diarrhea and weight loss. The chest radiography revealed fractures of the left sixth and seventh ribs. Examinations, including emission computed tomography, bone densitometry test, and other serum parameters, were performed, but could not identify the definite etiology of the rib fractures. One month later, the patient suffered from aggravating multiple rib fractures due to the ineffective treatment, persistent hypocalcaemia and malnutrition. Conclusions This is the first case of a CCS patient with multiple rib fractures. Although the association between CCS and multiple rib fractures in this case remains uncertain, we presume that persistent hypocalcaemia and malnutrition contribute to this situation, or at least aggravate this rare complication. Besides, since prolonged corticosteroid therapy will result in an increased risk of osteoporotic

    Jaw cyst-Basal cell nevus-Bifid rib syndrome or Gorlin-Goltz syndrome involves multiple organ system. The most common findings include multiple odontogenic keratocysts in the jaws and basal cell nevus on the skin that have an early age onset. These multiple odontogenic keratocysts warrant aggressive treatment at the earliest because of the damage and possible complications associated with them. Recurrence in these lesions is the most characteristic feature that has to be taken in consideration while explaining the prognosis to the patient. A case report of a child affected with Gorlin-Goltz syndrome diagnosed, treated and followed at this hospital is presented here.

    2012-01-01

    Cervical spondylosis is a broad term which describes the age related chronic disc degeneration, which can also affect the cervical vertebrae, the facet and other joints and their associated soft tissue supports. Evidence of spondylitic change is frequently found in many asymptomatic adults. Radiculopathy is a result of intervertebral foramina narrowing. Narrowing of the spinal canal can result in spinal cord compression, ultimately resulting in cervical spondylosis myelopathy. This review article examines the current literature in relation to the cervical spondylosis and describes the three clinical syndromes of axial neck pain, cervical radiculopathy and cervical myelopathy.

    2015-01-01

    Full Text Available Short-rib polydactyly syndrome is an autosomal recessively inherited lethal skeletal dysplasia. The syndrome is characterized by marked narrow fetal thorax, short extremities, micromelia, cleft palate/lip, polydactyly, cardiac and renal abnormalities, and genital malformations. In cases with pulmonary hypoplasia, persistent pulmonary hypertension of the newborn can develop. In this paper, we present a term newborn with persistent pulmonary hypertension of the newborn, which has developed secondary to short-rib polydactyly syndrome and was resistant to therapy with inhaled nitric oxide and oral sildenafil.

    2014-02-15

    Cerebro-costo-mandibular syndrome (CCMS) describes a triad of mandibular hypoplasia, brain dysfunction and posterior rib defects (''rib gaps''). We present the CT imaging for a 2-year-old girl with CCMS that highlights the rib gap defects and shows absent transverse processes with abnormal fusion of the ribs directly to the vertebral bodies. We argue that this is likely to relate to abnormal lateral sclerotome development in embryology, with the failure of normal costo-vertebral junctions compounding impaired thoracic function. The case also highlights the use of CT for specific indications in skeletal dysplasia. (orig.)

    Defects of ciliogenesis have been implicated in a wide range of human phenotypes and play a crucial role in signal transduction and cell-cycle coordination. We used homozygosity mapping in two families with autosomal-recessive short-rib polydactyly syndrome Majewski type to identify mutations in NEK1 as an underlying cause of this lethal osteochondrodysplasia. NEK1 encodes a serine/threonine kinase with proposed function in DNA double-strand repair, neuronal development, and coordination of cell-cycle-associated ciliogenesis. We found that absence of functional full-length NEK1 severely reduces cilia number and alters ciliar morphology in vivo. We further substantiate a proposed digenic diallelic inheritance of ciliopathies by the identification of heterozygous mutations in NEK1 and DYNC2H1 in an additional family. Notably, these findings not only increase the broad spectrum of ciliar disorders, but suggest a correlation between the degree of defective microtubule or centriole elongation and organization and the severity of the resulting phenotype.

    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.

    Full Text Available Brown-Sequard syndrome is commonly seen in the setting of spinal trauma or an extramedullary spinal neoplasm. The clinical picture reflects hemisection of the spinal cord. We report a rare case of Brown-Sequard syndrome caused by a large cervical herniated disc. A 63-year-old man presented with progressive right hemiparesis and disruption of pain and temperature sensation on the left side of the body. Magnetic resonance imaging showed large C3-C4 disc herniation compressing the spinal cord at that level, with severe canal stenosis from C4 through C7. Decompressive cervical laminoplasty was performed. After surgery, complete sensory function was restored and a marked improvement in motor power was obtained.

    Short-rib polydactyly syndrome type III is an autosomal recessive lethal skeletal ciliopathy, which is phenotypically similar to nonlethal asphyxiating thoracic dystrophy. Mutations in DYNC2H1 have been identified in both of these disorders, indicating that they are variants of a single disorder. However, short-rib polydactyly syndrome type III is the more severe variant. Here, we report novel compound heterozygous mutations in DYNC2H1 (p.E1894fsX10 and p.R3004C) in a patient with typical short-rib polydactyly syndrome type III phenotype. R3004 is located within the microtubule-binding domain of DYNC2H1, and its substitution is predicted to disrupt the interaction with microtubules. Considering the severe phenotype of our patient, our findings suggest that R3004 may be a key residue for the microtubule-binding affinity of dynein.

    2016-01-01

    Summary Background Eagle syndrome is a condition caused by an elongated styloid process. Unilateral face, neck and ear pain, stinging pain, foreign body sensation and dysphagia can be observed with this syndrome. Rarely, the elongated styloid process may cause pain by compressing the cervical segment of the internal carotid and the surrounding sympathetic plexus, and that pain spreading along the artery can cause neurological symptoms such as vertigo and syncope. Case Report In this case report we presented a very rare eagle syndrome with neurological symptoms that occurred suddenly with cervical rotation. The symptoms disappeared as suddenly as they occurred, with the release of pressure in neutral position. We also discussed CT angiographic findings of this case. Conclusions Radiological diagnosis of the Eagle syndrome that is manifested with a wide variety of symptoms and causes diagnostic difficulties when it is not considered in the differential diagnosis is easy in patients with specific findings. CT angiography is a fast and effective examination in terms of showing compression in patients with the Eagle syndrome that is considered to be atypical and causes vascular compression.

    Our previous study of whiplash injury found that abnormalities in the cervical muscles cause autonomic dystonia. Further research has found that abnormalities in the cervical muscles cause headache, chronic fatigue syndrome, vertigo, and dizziness. We named this group of diseases cervical neuro-muscular syndrome. Patients treated within a 2-year period from April 1, 2002 to March 31, 2004 reported good outcomes in 83.8% for headache, 88.4% for vertigo and dizziness, 84.5% for chronic fatigue syndrome, 88.0% for autonomic dystonia, and 83.7% for whiplash-associated disorder. A large number of outpatients present with general malaise, including many general physical complaints without identifiable cause. We propose that treatment of the cervical muscle is effective for general malaise.

    2015-01-01

    Pain is a complex and multifactorial phenomenon that depends on the interaction of biopsychosocial factors. Between 15-25% of adults suffer from chronic pain at some point in their lives. Cervical chronic pain is considered a public health problem affecting 9.6% men and 21.9% women, according to the latest National Health Survey 2011-12. A high percentage of medical consultations due to muscle pain turn out to be myofascial pain syndrome (MPS). Its existence implies the presence of myofascial trigger points which can be latent or active throughout the whole population. The aim of this review is to update knowledge in the various therapies applied by the physiotherapist in the treatment of this syndrome at cervical level. From the review it appears that some of the most used techniques that may be useful in the short or medium term are: ischemic compression and/or trigger point pressure release and dry needling. Furthermore, various combinations of treatment modalities are used to treat this syndrome, taking other aspects into account, such as education.

    Pain is a complex and multifactorial phenomenon that depends on the interaction of biopsychosocial factors. Between 15-25% of adults suffer from chronic pain at some point in their lives. Cervical chronic pain is considered a public health problem affecting 9.6% men and 21.9% women, according to the latest National Health Survey 2011-12. A high percentage of medical consultations due to muscle pain turn out to be myofascial pain syndrome (MPS). Its existence implies the presence of myofascial trigger points which can be latent or active throughout the whole population. The aim of this review is to update knowledge in the various therapies applied by the physiotherapist in the treatment of this syndrome at cervical level. From the review it appears that some of the most used techniques that may be useful in the short or medium term are: ischemic compression and/or trigger point pressure release and dry needling. Furthermore, various combinations of treatment modalities are used to treat this syndrome, taking other aspects into account, such as education. PMID:25963463

    Jeune asphyxiating thoracic dystrophy (ATD) is an autosomal-recessive chondrodysplasia characterized by short ribs and a narrow thorax, short long bones, inconstant polydactyly, and trident acetabular roof. ATD is closely related to the short rib polydactyly syndrome (SRP) type III, which is a more severe condition characterized by early prenatal expression and lethality and variable malformations. We first excluded IFT80 in a series of 26 fetuses and children belonging to 14 families diagnosed with either ATD or SRP type III. Studying a consanguineous family from Morocco, we mapped an ATD gene to chromosome 11q14.3-q23.1 in a 20.4 Mb region and identified homozygous mutations in the cytoplasmic dynein 2 heavy chain 1 (DYNC2H1) gene in the affected children. Compound heterozygosity for DYNC2H1 mutations was also identified in four additional families. Among the five families, 3/5 were diagnosed with ATD and 2/5 included pregnancies terminated for SRP type III. DYNC2H1 is a component of a cytoplasmic dynein complex and is directly involved in the generation and maintenance of cilia. From this study, we conclude that ATD and SRP type III are variants of a single disorder belonging to the ciliopathy group.

  15. Pharyngeal-cervical-brachial variant of Guillain-Barre syndrome.

    2014-03-01

    The pharyngeal-cervical-brachial (PCB) variant of Guillain-Barré syndrome is defined by rapidly progressive oropharyngeal and cervicobrachial weakness associated with areflexia in the upper limbs. Serial nerve conduction studies suggest that PCB represents a localised subtype of Guillain-Barré syndrome characterised by axonal rather than demyelinating neuropathy. Many neurologists are unfamiliar with PCB, which is often misdiagnosed as brainstem stroke, myasthenia gravis or botulism. The presence of additional ophthalmoplegia and ataxia indicates overlap with Fisher syndrome. Half of patients with PCB carry IgG anti-GT1a antibodies which often cross-react with GQ1b, whereas most patients with Fisher syndrome carry IgG anti-GQ1b antibodies which always cross-react with GT1a. Significant overlap between the clinical and serological profiles of these patients supports the view that PCB and Fisher syndrome form a continuous spectrum. In this review, we highlight the clinical features of PCB and outline new diagnostic criteria. PMID:23804237

    The short-rib polydactyly (SRP) syndromes are a heterogeneous group of perinatal lethal skeletal disorders with polydactyly and multisystem organ abnormalities. Homozygosity by descent mapping in a consanguineous SRP family identified a genomic region that contained DYNC2H1, a cytoplasmic dynein involved in retrograde transport in the cilium. Affected individuals in the family were homozygous for an exon 12 missense mutation that predicted the amino acid substitution R587C. Compound heterozygosity for one missense and one null mutation was identified in two additional nonconsanguineous SRP families. Cultured chondrocytes from affected individuals showed morphologically abnormal, shortened cilia. In addition, the chondrocytes showed abnormal cytoskeletal microtubule architecture, implicating an altered microtubule network as part of the disease process. These findings establish SRP as a cilia disorder and demonstrate that DYNC2H1 is essential for skeletogenesis and growth.

    Neuroblastoma is infrequently associated with paraneoplastic syndromes. Amongst the few, opsomyoclonus (Kinsbourne syndrome) is the most common neurological paraneoplastic syndrome and diarrhea secondary to increased secretion of vasoactive intestinal peptide (Kerner-Morrison syndrome), hormonal paraneoplastic syndrome. Hypothalamic dysfunction (HD) is a rare disorder and its manifestation as a paraneoplastic syndrome of neuroblastoma is uncommonly reported. We present an interesting case of an unrelenting cervical neuroblastoma associated with HD, which posed a therapeutic challenge. PMID:27695211

    The aims of this study are to determine the frequency of fibromyalgia syndrome (FMS) in patients with chronic cervical myofascial pain (CMP) and to investigate the FMS characteristics in CMP patients. Ninty-three patients with CMP and 30 age-matched healthy women were included in this study. Main outcome measures included visual analog scale (VAS), Beck Depression Inventory (BDI), and pain pressure thresholds. CMP patients were evaluated for the existence of FMS. The severity of FMS was assessed with total myalgic score (TMS) and control point score (CPS). Most common clinical characteristics of FMS were noted. Of the 93 CMP subjects, 22 (23.6%) patients fulfilled the classification criteria for FMS. Number of tender points were higher (p=0.0), while TMS (p=0.0) and CPS (p=0.0) values were lower in comorbid CMP and FMS patients than regional CMP group. There were statistically significant differences between regional CMP patients and comorbid CMP and FMS patients regarding presence of fatigue (p=0.0) and irritable bowel syndrome (p=0.022). There was no statistically significant difference between patient groups regarding VAS values (p>0.05). BDI values of the regional CMP were significantly lower than comorbid CMP and FMS patients (p=0.011). In conclusion, we found that nearly a quarter of CMP patients were comorbid with FMS, and psychological and comorbid symptoms were more prominent in comorbid patients. We thought that, these two syndromes might be overlapping conditions and as a peripheral pain generator or inducer of central sensitisation, MPS might lead to FMS or precipitate and worsen the FMS symptoms.

    Full Text Available Background and Purpose: Myofascial pain syndrome (MPS is a syndrome presenting with acute or chronic regional pain originating from trigger points (TPs localized in the muscles or the fascia. TPs are local points showing high irritability, sensitivity to finger pressure and causing characteristic referred pain. The aim of this case study is to assess the effectiveness of cranio-cervical training on neck disability, endurance of deep cervical muscles and pressure pain threshold in a patient with cervical myofascial pain syndrome. Case description: A 36 year old female who was diagnosed with myofascial pain syndrome. She received cranio cervical training, a low load endurance exercises in order to train and/or to regain muscle control of the cervicoscapular and craniocervical regions. The patient received the treatment program for 10 to 15 minutes. The frequency of treatment is five days in a week for a period of 3 weeks. Outcome: The outcome measures were neck disability index, pressure pain threshold and deep cervical endurance test, which were measured prior to treatment and at the end of third week. Conclusion: The craniocervical training programme for a patient with myofascial pain syndrome found to be effective in reducing neck disability, improving the pressure pain threshold and deep cervical flexor muscle endurance.

    Ehlers-Danlos syndrome (EDS) is an umbrella term for a growing group of hereditary disorders of the connective tissue mainly manifesting with generalized joint hypermobility, skin hyperextensibility, and vascular and internal organ fragility. In contrast with other well known heritable connective tissue disorders with severe cardiovascular involvement (e.g., Marfan syndrome), most EDS patients share a nearly normal life span, but are severely limited by disabling features, such as pain, fatigue and headache. In this work, pertinent literature is reviewed with focus on prevalence, features and possible pathogenic mechanisms of headache in EDSs. Gathered data are fragmented and generally have a low level of evidence. Headache is reported in no less than 1/3 of the patients. Migraine results the most common type in the hypermobility type of EDS. Other possibly related headache disorders include tension-type headache, new daily persistent headache, headache attributed to spontaneous cerebrospinal fluid leakage, headache secondary to Chiari malformation, cervicogenic headache and neck-tongue syndrome, whose association still lacks of reliable prevalence studies. The underlying pathogenesis seems complex and variably associated with cardiovascular dysautonomia, cervical spine and temporomandibular joint instability/dysfunction, meningeal fragility, poor sleep quality, pain-killer drugs overuse and central sensitization. Particular attention is posed on a presumed subclinical cervical spine dysfunction. Standard treatment is always symptomatic and usually unsuccessful. Assessment and management procedures are discussed in order to put some basis for ameliorating the actual patients' needs and nurturing future research. PMID:25655119

    Scalene myofascial pain syndrome is a regional pain syndrome wherein pain originates over the neck area and radiates down to the arm. This condition may present as primary or secondary to underlying cervical pathology. Although scalene myofascial pain syndrome is a well known medical entity, it is often misdiagnosed as being some other neck pain associated with radiculopathy, such as cervical disc prolapse, cervical spinal stenosis and thoracic outlet syndrome. Because scalene myofascial pain syndrome mimics cervical radiculopathy, this condition often leads to mismanagement, which can, in turn, result in persistent pain and suffering. In the worst-case scenarios, patients may be subjected to unjustifiable surgical intervention. Because the clinical findings in scalene myofascial pain syndrome are "pathognomonic", clinicians should be aware of ways to recognize this disorder and be able to differentiate it from other conditions that present with neck pain and rediculopathy. We present two cases of unilateral scalene myofascial pain syndrome that significantly impaired the patients' functioning and quality of life. This case report serves to create awareness about the existence of the syndrome and to highlight the potential morbidity due to clinical misdiagnosis.

    Objective To evaluate the impact of polyhydramnios on preoperative cervical length and whether cervical length recovery after amnioreduction during selective fetoscopic laser photocoagulation (SFLP) is associated with a greater gestational age at delivery in pregnancies complicated by twin-twin transfusion syndrome (TTTS). Methods Retrospective study of 50 pregnancies complicated by TTTS treated with SFLP between March 2010 and July 2014 at a single center. Preoperative maximum vertical pocket (MVP) was measured along with pre- and postoperative cervical length. A cervical length difference was calculated, with a difference of ± 3 mm considered no change. Results Only 12 (34%) patients showed an increased cervical length after amnioreduction during laser surgery. There was no statistical difference between either negative or positive change in cervical length groups and mean gestational age at delivery (p = 0.82). There also was no correlation between preoperative MVP and preoperative cervical length (p = 0.36) or gestational age at delivery (p = 0.77). However, there was a statistically shorter mean preoperative cervical length in patients who delivered polyhydramnios does not correlate with preoperative cervical length, and variability of the cervix postoperatively does not appear to affect gestational age at delivery.

    2005-01-01

    Objective: To explore the clinical characteristics and new treatment for syndrome of craniocerebral-cervical vertebral injury. Methods: The clinical data of 52 patients with head injury accompanied by neck injury were analyzed retrospectively. Results: Craniocerebral injury could result in damage to cervical vertebrae, muscles, vessels and nerves, and even cause vertebral artery injury, which may lead to insufficient blood-supply of vertebral-basal artery. All patients were treated with cervical vertebral traction and the results were good. Conclusions: Acute craniocerebral injury with symptom of insufficient blood-supply of vertebral-basal artery, evident neurosis and atlas-axis half-dislocation in X-ray should be treated by cervical vertebral traction, which will yield better outcome.

    We report a case of left upper cervical posterior spinal artery (PSA) syndrome caused by atherosclerosis of the left vertebral artery. A 70-year-old female experienced sudden dizziness and paralysis of the left upper and lower limbs. Diffusion-weighted magnetic resonance imaging (DWI) of the brain showed high signal intensity at the vermis and lower left hemisphere of the cerebellum, and magnetic resonance angiography showed that the entire left vertebral artery was thin. The patient was treated with an intravenous infusion of tissue plasminogen activator 2 hours after symptom onset and made a full recovery. Repeat DWI, fluid-attenuated inversion recovery images, and T2-weighted images showed high signal intensity in the left upper cervical PSA area from the lower medulla oblongata to the C2 level in addition to the cerebellum. Previously reported cases of cervical posterior artery syndrome are reviewed. PMID:27012218

    This study was aimed to explore the anterior cervical surgery methods to treat central cord syndrome without radiographic spinal fracture-dislocation (CCSWORFD), retrospectively analyze the cases of CCSWORFD, and evaluate the curative effect of anterior cervical surgery methods for CCSWORFD. Twenty four cases of CCSWORFD (19 males and 5 females), all suffering from cervical hyperextension injury, between 45-68 (average 59) years old, were operated on by anterior cervical surgery methods. Among these, 18 cases had been followed up for 6-24 (average 15) months; 18 cases, who had anterior decompression and plate fixation with titanium mesh bone grafting or iliac bone grafting achieved reliable effects based on the Japanese Orthopedics Association (JOA) evaluation (improved scores of cases with titanium mesh bone grafting, t = 2.800, P0.05). Most of these cases had degeneration of cervical vertebra. The decompression which relieves the oppression to the spinal cord can help lessen edema of the spinal cord, and early fixation for stability of cervical vertebra is better for the recovery of spinal cord injury. Anterior operation with titanium mesh bone grafting or iliac bone grafting are both reliable curative methods for CCSWORFD, and titanium mesh bone grafting can avoid the trauma of the supplying graft. Mesh bone grafting can also shorten hospital stay.

    2002-04-01

    Full Text Available Abstract Background Klippel-Feil syndrome is defined as congenital fusion of two or more cervical vertebrae and is believed to result from faulty segmentation along the embryo's developing axis during weeks 3–8 of gestation. Persons with Klippel-Feil syndrome and cervical stenosis may be at increased risk for spinal cord injury after minor trauma as a result of hypermobility of the various cervical segments. Persons with Klippel-Feil Syndrome often have congenital anomalies of the urinary tract as well. Case presentation A 51-year male developed incomplete tetraplegia in 1997 when he slipped and fell backwards hitting his head on the floor. X-rays of cervical spine showed fusion at two levels: C2 and C3 vertebrae, and C4 and C5 vertebrae. Intravenous urography (IVU revealed no kidneys in the renal fossa on both sides, but the presence of crossed, fused renal ectopia in the left ilio-lumbar region. This patient had a similar cervical spinal cord injury about 15 years ago, when he developed transient numbness and paresis of the lower limbs following a fall. Discussion and Conclusion 1 Persons with Klippel-Feil syndrome should be made aware of the increased risk of sustaining transient neurologic deterioration after minor trauma if there is associated radiographic evidence of spinal stenosis. 2 Patients with Klippel-Feil syndrome often have congenital anomalies of the urinary tract. Our patient had crossed, fused, ectopia of kidney. 3 When patients with Klippel-Feil syndrome sustain tetraplegia they have increased chances of developing urinary tract calculi. Treatment of kidney stones may pose a challenge because of associated renal anomalies. 4 Health professionals caring for cervical spinal cord injury patients with Klippel-Feil syndrome and renal anomalies should place emphasis on prevention of kidney stones. A large fluid intake is recommended for these patients, as a high intake of fluids is still the most powerful and certainly the most

    A 26-year-old woman with a past history of fetal skeletal dysplasia was referred to our institution at 24weeks of gestation following a routine sonographic diagnosis of short limbs in the fetus. A fetal ultrasound showed short limbs, a narrow thorax, short ribs with marginal spurs, and polydactyly. Conventional cytogenetics analysis of cultured amniocytes demonstrated that the fetal karyotype was normal. Using targeted exome sequencing of 226 known genes implicated in inherited skeletal dysplasia, we identified compound heterozygous mutations in the DYNC2H1 gene in the fetus with short rib-polydactyly syndrome, type III (SRPS III), c.1151 C>T(p.Ala384Val) and c.4351 C>T (p.Gln1451*), which were inherited from paternally and maternally, respectively. These variants were further confirmed using Sanger sequencing and have not been previously reported. To our knowledge, this is the first report of DYNC2H1 mutations causing SRPS III, in the Chinese population. Our findings expand the number of reported cases of this rare disease, and indicate that targeted next-generation sequencing (NGS) is an accurate, rapid, and cost-effective method in the genetic diagnosis of fetal skeletal dysplasia.

    Subjects with myofascial pain of muscles of the neck region may present with various clinical symptoms. The aim of this study was to explore the demographics features, clinical findings and functional status in a group of patients presenting with myofascial pain of the cervical muscles. 94 cervical myofascial pain syndrome patients were recruited from the out-patient clinic. Evaluated of patient short form health survey (SF-36), pain, depression, patient demographics and physical examinations. Outcome measures; SF-36 Health Survey, visual analog scale, Beck Depression Inventory, history, physical examination. A total of 82 patients with a diagnosis of cervical myofascial syndrome were included in the study. All patients were in the young age group 37.4+/-9, and 87.8% were females. 53.1% had trigger points in the trapezius muscle with high percentage of autonomic phenomena like skin reddening, lacrimation, tinnitus and vertigo. 58.5% of the series had suffered from former cervical trauma and 40.2% also had fibromyalgia syndrome and 18.5% had benign Joint hypermobility syndrome. Younger female patients presenting with autonomic phenomena and early onset cervical injury should be examined for cervical myofascial pain syndrome and also for fibromyalgia syndrome since this study demonstrated a high percentage of fibromyalgia syndrome in these patients.

    Periodic fever, aphthous stomatitis, pharyngotonsillitis, cervical adenopathy (PFAPA) syndrome, which is characterized by periodic episodes of high fever, aphthous stomatitis, pharyngitis, and cervical adenitis, is of unknown etiology and manifests usually before 5 years of age. A patient with periodic fever, aphthous stomatitis, pharyngotonsillitis, cervical adenopathy syndrome simultaneously presenting with genital ulcers has not been reported previously. We describe a 12-year-old Chinese girl with a 2-year history of periodic fever, aphthous stomatitis, pharyngotonsillitis, cervical adenopathy syndrome who exhibited vulvar ulcers accompanying an episode of febrile periodic fever, aphthous stomatitis, pharyngotonsillitis, and cervical adenopathy. Although during a 1-year follow-up this girl did not manifest typical symptoms/signs of Behçet's disease except recurrent oral aphthae and genital ulcers, it is possible that periodic fever, aphthous stomatitis, pharyngotonsillitis, cervical adenopathy syndrome and Behçet's disease could have overlapping manifestations. Furthermore, this report would add to the evidence of a wide variation in the clinical symptomatology of PFAPA syndrome.

    Full Text Available PFAPA (periodic fever, aphtous stomatitis, pharingitis, cervical adenitis or Marshall’s syndrome is one of the rare periodic fever conditions appearing in children. Its cause is unknown. This syndrome may continue for several years. During interictal period the child is quite well, grows and develops normally. The disease should be differentiated from Behcet’s disease, cyclic neutropenia, familial Mediterranean fever, familial Ireland fever, hyperimmunoglobulinemia D syndrome, systemic juvenile idiopathic arthritis, chronic tonsillitis, some infectious diseases. Many drugs are used for the treatment of PFAPA syndrome: antibiotics, non-steroidal anti-inflammatory drugs, chloroquin, antiviral drugs, glucocorticoids, cimetidin. Tonsillectomy is used quite often. Analysis of the literature data shows that best results may be achieved with tonsillectomy (sometimes in combination with ade- notomy. PFAPA in a child of 2 years age diagnosed for the first time in Russian pediatric rheumatology is described.

    Short rib-polydactyly syndrome type III (SRPS3) is a perinatal lethal skeletal disorder with polydactyly and multisystem organ abnormalities. While ultrasound of the fetus can detect skeletal abnormalities characteristic of SRPS3, the syndrome is often difficult to diagnose before birth. As SRPS3 is an autosomal recessive disorder, identification of the gene mutations involved could lead to the development of prenatal genetic testing as an accurate method of diagnosis. In this study, we describe genetic screening approaches to identify potential abnormalities associated with SRPS3. Karyotype analysis, array comparative genomic hybridization (aCGH), and next-generation panel sequencing were each performed on a fetus showing signs of the disorder, as well as on the mother and father. Karyotype and aCGH results revealed no abnormalities. However, next-generation panel sequencing identified novel mutations in the DYNC2H1 gene. The fetus was compound heterozygous for both a missense mutation c.8313A > T and a frameshift mutation c.10711_10714delTTTA in the DYNC2H1 gene, which were inherited from the mother and father, respectively. These variants were further confirmed using Sanger sequencing and have not been previously reported. Our study indicates the utility of using next-generation panel sequencing in screening for novel disease-associated mutations.

    Aim: The aim of this study was to investigate the levels of depression, pain and disability in patients with chronic cervical miyofascial pain syndrome (MPS and to determine their association with quality of life. Material and Method: Forty patients with Cervical MPS and 40 age and sex-matched healthy controls enrolled in this study. The social and demographic characteristics of the patients and controls were examined. All patients and controls were evaluated with respect to pain (at night, rest and movement and assessed by visual analog scale (VAS. Neck disability index (NDI was used to calculate functional disability. Quality of life was evaluated with the the Short Form 36 Health Survey (SF-36. Also all of the patients and controls underwent Beck depression inventory (BDI. Results: There was no statistical difference between the patients and control cases according to demographical data. The SF-36 scores of the study patients were lower than controls. NDI, BDI and VAS scores were higher in the patients with chronic cervical MPS compared to controls. BDI scores of the patients with chronic cervical MPS  were negatively and closely associated with subparameters of the SF-36 (physical function (r:-0,599, p<0.001, role limitations due to physical functioning (r:-0,558, p<0.001, bodily pain (r:-0.540, p<0.001, general health (r:- 0,708 p<0.001, vitality (r:-0,692, p<0.001, social functioning (r:-0,559, p<0.001, role limitations due to emotional problems (r:-0,537, p<0.001 and mental health (r: -0,787, p<0.001. Discussion: BDI scores are higher in patients with chronic cervical MPS than healthy controls and negatively affect their quality of life. Psychiatric evaluation of the patients with chronic cervical MPS may improve their quality of life and treatments outcome.

  7. Case Report: Cervical chondrocalcinosis as a complication of Gitelman syndrome [version 1; referees: 2 approved

    2016-05-01

    Full Text Available Gitelman syndrome is an inherited tubulopathy leading to a hypokalaemic metabolic alkalosis with hypomagnesaemia and hypocalciuria. Most cases are due to mutations in SLC12A3, encoding the apical thiazide sensitive co-transporter in the distal convoluted tubule. Musculoskeletal effects of Gitelman syndrome are common, including muscle weakness, tetany and cramps. Chronic hypomagnesaemia can lead to chondrocalcinosis, which often affects knees but can affect other joints. Here we present a case of Gitelman syndrome complicated by cervical chondrocalcinosis leading to neck pain and numbness of the fingers. Treatments directed at correcting both hypokalaemia and hypomagnesaemia were initiated and allowed conservative non-surgical management of the neck pain. Recognition of chondrocalcinosis is important and treatments must be individualised to correct the underlying hypomagnesaemia.

    Brachioradial pruritus is a chronic sensory neuropathy of unknown etiology which affects the skin of the shoulders, arms and forearms on the insertion of the brachioradialis muscle. We describe the case of a 60-yearold woman recently diagnosed with multiple myeloma who refers paresis, severe pruritus and itching lesions on the right arm with 6 months of evolution. Investigation led to a diagnosis of Brachioradial pruritus consequent to the presence of cervical disc herniation and Parsonage-Turner syndrome. The patient started gabapentin 900mg/day with good control of itching. Corticosteroids and antihistamines are often ineffective in the treatment of BP. Gabapentin has been used with encouraging results. All patients with Brachioradial pruritus should be evaluated for cervical spine injuries. PMID:26131874

    An improvement is achieved by palliative X-ray irradiation in about 70% out of 47 patients with scapulohumeral periarthritis and local cervical syndrome and/or cervicobrachial syndrome which was hitherto resistant to medicomechanical treatment. Higher rates of success (84%) can be achieved if the patients present an identical symptomatology, but less severe alterations of the vertebral column, even if the vertebral column is not irradiated. In case of severe alterations of the vertebral column, the success of palliative irradiation is diminished, even if the cervical vertebral column is additionally irradiated. PMID:2411026

    Static X-rays recorded at two planes from the cervical spine of 286 patients were evaluated and were compared to findings obtained from 50 probands without complaints. The patients complained about problems relating to vertebrogenic pain syndrome of the cervical spine, including vertigo of cervical origin. They were grouped by four sets of clinical symptoms (cephalgia, vertigo, locally delimited complaints and cervicobrachial syndrome). No statistically significant differences were found to exist among the groups of probands with regard to radiographic morphology, static condition nor impairment of relations. Particular reference is made in this paper to reversible function disorders and their major role among the multifactorial causes of the cervical syndrome. Indications are derived from these observations for primary X-ray examination of the cervical spine. (orig.).

    Full Text Available The dropped head syndrome (DHS is a disabling condition caused by severe weakness of the neck extensor muscles causing progressive reducible kyphosis of the cervical spine and the inability to hold the head up. Weakness can occur in isolation or in association with a generalized neuromuscular disorder. Isolated cases are owed to the late onset of noninflammatory myopathy designated as INEM, where persistent chin to chest deformity may gradually cause or aggravate preexisting degenerative changes of the cervical spine and ultimately result in myelopathy. In review of the literature, we could find only 5 cases, with no unique guidelines to address the management of these two concomitant pathologies. Herein, a 69-year-old man who had developed cervical myelopathy 2 years after being affected by isolated dropped head syndrome is presented. Chin to chest deformity and cervical myelopathy were managed through three-level anterior cervical discectomy and fusion (ACDF combined with decompressive cervical laminectomy and stabilization with C2 to C7 pedicle screw-rod construct. At 4-month follow-up, despite recovery in patient’s neurological status, flexion deformity reappeared with recurrence of dropped head due to C7 pedicle screws pull-out. However, this was successfully managed with extension of the construct to the upper thoracic levels.

    2016-09-01

    Cervical radiculopathy is a common clinical scenario. Patients with radiculopathy typically present with neck pain, arm pain, or both. We review the epidemiology of cervical radiculopathy and discuss the diagnosis of this condition. This includes an overview of the pertinent findings on the patient history and physical examination. We also discuss relevant clinical syndromes that must be considered in the differential diagnosis including peripheral nerve entrapment syndromes and shoulder pathology. The natural history of cervical radiculopathy is reviewed and options for management are discussed. These options include conservative management, non-operative modalities such as physical therapy, steroid injections, and operative intervention. While the exact indications for surgical intervention have not yet been elucidated, we provide an overview of the available literature regarding indications and discuss the timing of intervention. The surgical outcomes of anterior cervical decompression and fusion (ACDF), cervical disc arthroplasty (CDA), and posterior cervical foraminotomy (PCF) are discussed. PMID:27250042

  18. Failure of cervical arthroplasty in a patient with adjacent segment disease associated with Klippel-Feil syndrome

    Directory of Open Access Journals (Sweden)

    Ioannis D Papanastassiou

    2011-01-01

    Full Text Available Cervical arthroplasty may be justified in patients with Klippel-Feil syndrome (KFS in order to preserve cervical motion. The aim of this paper is to report an arthroplasty failure in a patient with KFS. A 36-year-old woman with KFS underwent two-level arthroplasty for adjacent segment disc degeneration. Anterior migration of the cranial prosthesis was encountered 5 months postoperatively and was successfully revised with anterior cervical fusion. Cervical arthroplasty in an extensively stiff and fused neck is challenging and may lead to catastrophic failure. Although motion preservation is desirable in KFS, the special biomechanical features may hinder arthroplasty. Fusion or hybrid constructs may represent more reasonable options, especially when multiple fused segments are present.

    Clinical observations suggest the need for changing therapeutic management to a more active one in cases of cervical spine injury with damage to the spinal cord and nerve roots or brachial plexus. In 248 patients with these injuries treated initially conservatively the incidence of cervicobrachial pain was analysed. Neuralgic pains were present in 31.5% of cases, causalgic pains in 2.4% and sympathalgic pains in 2%. Conservative treatment conducted in these patients (89 cases) during many months after trauma had no effect on return of mobility. Long-term application of physioterapy prevented only temporarily the development of trophic changes and only partially relieved pains. Only surgical decompression of the spinal cord or spinal nerves with stabilization of damaged vertebrae caused disappearance of painful syndromes and improvement in the motor activity of the extremities. These observations show that early surgical intervention for decompression of the spinal cord, roots or brachial plexus should be advocated in these cases.

Design Retrospective study of patients evaluated between July 2008 and October 2011. 3. Setting Seven pediatric dermatology centers. 4. Patients 32 infants with definite PHACE syndrome and cervical and/or intracranial arterial anomalies. 5. Intervention Oral propranolol: average dose of 1.8 mg/kg/day divided t.i.d. or b.i.d., for an average duration of 12.3 months. 6. Main Outcome Measure Adverse neurologic events. 7. Results 7/32 (22%) patients were categorized as higher-risk for stroke, defined on MRA as severe, long-segment narrowing or non-visualization of major cerebral or cervical vessels without anatomic evidence for collateral circulation, often in the presence of concomitant cardiovascular comorbidities. Only 1 patient developed a change in neurologic status during propranolol treatment: a mild right hemiparesis that remained static and improved while propranolol was continued. An additional 3 patients had worsening hemangioma ulceration and/or tissue necrosis during therapy. 8. Conclusions This is the largest report thus far of PHACE patients treated with propranolol. While no catastrophic neurologic events occurred, serious complications, particularly severe ulcerations were seen in a minority of patients, and given the sample size we cannot negate the possibility that propranolol could augment the risk of stroke in this population. We continue to advise caution in using systemic beta-blockers, particularly for children with vascular anomalies at higher risk for stroke. Use of the lowest possible dosage, slow dosage titration, and t.i.d. dosing in order to minimize abrupt changes in blood pressure and close follow-up, including neurologic consultation as needed, are recommended.

    Short-rib polydactyly (SRP) syndrome type III, or Verma-Naumoff syndrome, is an autosomal-recessive chondrodysplasia characterized by short ribs, a narrow thorax, short long bones, an abnormal acetabulum, and numerous extraskeletal malformations and is lethal in the perinatal period. Presently, mutations in two genes, IFT80 and DYNC2H1, have been identified as being responsible for SRP type III. Via homozygosity mapping in three affected siblings, a locus for the disease was identified on chromosome 9q34.11, and homozygosity for three missense mutations in WDR34 were found in three independent families, as well as compound heterozygosity for mutations in one family. WDR34 encodes a member of the WD repeat protein family with five WD40 domains, which acts as a TAK1-associated suppressor of the IL-1R/TLR3/TLR4-induced NF-κB activation pathway. We showed, through structural modeling, that two of the three mutations altered specific structural domains of WDR34. We found that primary cilia in WDR34 mutant fibroblasts were significantly shorter than normal and had a bulbous tip. This report expands on the pathogenesis of SRP type III and demonstrates that a regulator of the NF-κB activation pathway is involved in the pathogenesis of the skeletal ciliopathies.

    PFAPA syndrome represents the most common cause of recurrent fever in children in European populations, and it is characterized by recurrent episodes of high fever, pharyngitis, cervical adenitis, and aphthous stomatitis. Many possible causative factors have been explored so far, including infectious agents, immunologic mechanisms and genetic predisposition, but the exact etiology remains unclear. Recent findings demonstrate a dysregulation of different components of innate immunity during PFAPA flares, such as monocytes, neutrophils, complement, and pro-inflammatory cytokines, especially IL-1β, suggesting an inflammasome-mediated innate immune system activation and supporting the hypothesis of an autoinflammatory disease. Moreover, in contrast with previous considerations, the strong familial clustering suggests a potential genetic origin rather than a sporadic disease. In addition, the presence of variants in inflammasome-related genes, mostly in NLRP3 and MEFV, suggests a possible role of inflammasome-composing genes in PFAPA pathogenesis. However, none of these variants seem to be relevant, alone, to its etiology, indicating a high genetic heterogeneity as well as an oligogenic or polygenic genetic background. PMID:26984802

    Full Text Available Abstract Introduction Even if performed by qualified physical therapists, spinal manipulation and mobilization can cause adverse events. This holds true particularly for the cervical spine. In light of the substantial risks, the benefits of cervical spine manipulation may be outweighed by the possibility of further injury. Case presentation We present the case of a 56-year-old Caucasian man with Forestier's disease who went to see a physiotherapist to relieve his aching neck while on a holiday trip. Following the procedure, he was transferred to a local hospital with a partial tetraplegic syndrome due to a cervical 6/7 luxation fracture. Reportedly, the physiotherapist took neither a detailed history, nor adequate diagnostic measures. Conclusions This case highlights the potentially dangerous complications associated with cervical spine mobilization/manipulation. If guidelines concerning cervical spine mobilization and manipulation practices had been followed, this adverse event could have been avoided.

    Carotid body tumours (CBT) are the most common tumours at the carotid bifurcation. Widening of the bifurcation is usually demonstrated on conventional angiography. This sign may also be produced by a schwannoma of the cervical sympathetic plexus. A 45-year-old patient presented with a neck mass. Investigations included contrast-enhanced CT, MRI and magnetic resonance arteriography with contrast enhancement. Radiologically, the mass was considered to be a CBT due to vascular enhancement and splaying of the internal and external carotid arteries. Intraoperatively, it was determined to be a cervical sympathetic chain schwannoma (CSCS). The patient had a postoperative complication of first-bite syndrome (FBS).Although rare, CSCS should be considered in the differential diagnosis for tumours at the carotid bifurcation. Damage to the sympathetic innervation to the parotid gland can result in severe postoperative pain characterised by FBS and should be considered in all patients undergoing surgery involving the parapharyngeal space.

    We retrospectively reviewed 633 hands in 362 patients who had idiopathic carpal tunnel syndrome and underwent carpal tunnel release between 1999 and 2009. Electrophysiological studies and simple radiographs of the wrist, cervical spine, and basal joint of the thumb were routinely checked, and patients were also assessed for the presence of trigger digit or de Quervain's disease before and after surgery. Among 362 patients, cervical arthritis was found in 253 patients (70%), and C5-C6 arthritis was the most common site. Basal joint arthritis of the thumb was observed in 216 (34%) of the 633 hands. Trigger digit or de Quervain's disease was observed in 85 of the 633 hands (13%) before surgery, and developed in 67 hands (11%) after surgery. Cervical arthritis, basal joint arthritis, and trigger digit commonly coexist with idiopathic carpal tunnel syndrome. Patient education about these disorders is very important when they coexist with idiopathic carpal tunnel syndrome.

    2015-06-01

    Full Text Available Case summary A 6-year-old male domestic shorthair cat presented with frequent food regurgitation and dysphagia. Plain thoracic radiographs revealed a calcified mass overlying the topography of the mediastinum, as well as dilation of the cervical portion of the esophagus due to an accumulation of food. Endoscopic examination showed a severe extraluminal esophageal stricture at the mediastinum entrance. Surgery and a gastric tube were declined by the cat’s owner, with palliative support preferred. However, 1 year later, the cat presented with severe cachexia, dysphagia, salivation, dehydration and inspiratory dyspnea. Thoracic computed tomography was performed to evaluate the possibility of surgical resection. A mass of bone density originating in the second left rib was observed. The mass did not appear to have invaded adjacent structures but marked compression of the mediastinal structures was observed. Surgical resection was performed and a prosthetic mesh was used to reconstruct the thoracic wall. Transient Horner’s syndrome developed in the left eye postoperatively, and was resolved within 4 weeks. Histopathology revealed a benign osteoma. Thirty-two months after surgery, the cat was well and free of disease. Relevance and novel information Rib tumors should be included in a differential diagnosis in cats with extraluminal esophageal stricture. CT should be performed for treatment planning. Surgical treatment was curative in this case.

    Full Text Available INTRODUCTION: This study was conducted with the aim of adapting the methods developed by Martins and Sakima to assess skeletal maturation by cervical vertebrae in the pubertal growth spurt (PGS curve. It also aimed to test the reliability and agreement between those methods and the method of hand and wrist radiograph when compared two by two and all together. METHODS: The sample comprised 72 radiographs, with 36 lateral radiographs of the head and 36 hand-wrist radiographs of 36 subjects with Down's syndrome (DS, 13 female and 23 male, aged between 8 years and 6 months and 18 years and 7 months, with an average age of 13 years and 10 months. RESULTS AND CONCLUSIONS: Results revealed that adapting the methods developed by Martins and Sakima to assess skeletal maturation by cervical vertebrae in the curve of PGS is practical and useful in determining the stage of growth and development of individuals. The stages of maturation evaluated by cervical vertebrae and ossification centers observed in radiographs of the hand and wrist were considered reliable, with excellent level of agreement between the methods by Hassel and Farman as well as Baccetti, Franchi and McNamara Jr and Martins and Sakima. Additionally, results revealed an agreement that ranged between reasonable to good for the three methods used to assess the skeletal maturation, showing statistical significance.

    Klippel-Feil syndrome (KFS) is a congenital developmental disorder of cervical spine, showing short neck with restricted neck motion, low hairline, and high thoracic cage due to multilevel cervical fusion. Radiculopathy or myelopathy can be accompanied. There were 2 patients who were diagnosed as KFS with exhibited radiological and physical characteristics. Both patients had stenosis and cord compression at C1 level due to anterior displacement of C1 posterior arch secondary to kyphotic deformity of upper cervical spine, which has been usually indicative to craniocervical fixation. One patient was referred due to quadriparesis detected after surgery for aortic arch aneurysmal dilatation. The other patient was referred to us due to paraparesis and radiating pain in all extremities developed during gynecological examinations. Decompressive C1 laminectomy was done for one patient and additional suboccipital craniectomy for the other. No craniocervical fixation was done because there was no spinal instability. Motor power improved immediately after the operation in both patients. Motor functions and spinal stability were well preserved in both patients for 2 years. In KFS patients with myelopathy at the C1 level without C1-2 instability, a favorable outcome could be achieved by a simple decompression without spinal fixation. PMID:26512291

    Abstract Background: We report 8 years of follow-up after decompression to treat cervical myelopathy in a patient with Coffin–Lowry syndrome (CLS). CLS is a rare X-linked semidominant syndrome associated with growth and psychomotor retardation, general hypotonia, and skeletal abnormalities. In this patient, the spinal cord was compressed by calcium pyrophosphate crystal deposition in the cervical yellow ligament (YL). To date, only 1 report has described clinical features after surgery for calcified cervical YL in CLS. Methods: A 15-year-old male with tetraplegia secondary to compression of the cervical spinal cord induced by a hypoplastic posterior arch of C1 and calcification of the YL from C2 to C7 was treated surgically with laminectomy from C1 to C7. The patient's history, clinical examination, imaging findings, and treatment are reported. The patient was incapable of speech because of mental retardation, so he could not describe his symptoms. Gait disturbance worsened over the 2 months before admission to our hospital. At admission, the patient could not move his extremities, and tendon reflexes of the upper and lower extremities were significantly increased. Computed tomography of the cervical spine showed YL calcification from C2 to C7. Magnetic resonance imaging showed consecutive compression of the cervical spinal cord. We diagnosed quadriplegia secondary to cervical cord damage and performed emergency surgery. Results: During C1–C7 laminectomy, YL calcification in C2–C7 was observed. The calcification was confirmed as calcium pyrophosphate by crystal analysis. Quadriplegia gradually resolved, and almost disappeared by 2 weeks after the operation. Cervical hyperlordosis was observed in radiographs starting from 1 month after the operation, but it has not progressed and is not associated with any symptoms. Conclusions: The efficacy of decompression continued, and no postoperative complications have occurred during at least 8 years of follow-up. PMID

  17. Rib fracture: Different radiographic projections

    International Nuclear Information System (INIS)

    Rib fracture is the most common thoracic injury. It is thought to be present in 10% of all traumatic injuries and in almost 40% of patients who sustained severe non-penetrating trauma. There are 12 pairs of ribs. This study reviews various methods of acquisition and reconstruction of radiographic images of traumatic rib fractures in order to determine the optimal views and to simplify rib fracture diagnostics. Eight different plain radiography pictures of ribs were performed with the patient in an erect position. The following projections were obtained in sequence: oblique at 45° or 30° angle on inspiration, oblique at 45° or 30° angle on expiration as well as 45° and 39° projections during slow and fast breathing. All radiographic examinations were performed using a Philips three-phase scanner installed at the Al- Razi Hospital in Jenin, Palestine. The results demonstrate that the 45° antero-posterior oblique projection performed on expiration is recommended for diagnostics and interpretation of traumatic rib fractures. Conclusion emerging from this study are such that for a 45° oblique view on expiration is recommended for radiographic imaging of patients with clinical signs of fracture, e.g. evaluation of lower rib fractures, while 45° oblique view during fast breathing is recommended for suspected upper rib fractures

    Full Text Available Background. PFAPA syndrome is a chronic disease that is characterized by recurrent episodes of high fever, aphthous stomatitis, pharyngitis, and cervical adenitis. Knowledge regarding the etiology of PFAPA is limited. Objectives. To provide up-to-date information considering etiology of PFAPA syndrome, by summarizing what has been explored and established in this area so far. Materials and Methods. PubMed, Web of Science, and Scopus databases were searched for pertinent reports. Eventually 19 articles were selected. The results were classified into categories regarding three areas of interest: familial occurrence, genetic basis, and immunological mechanisms of PFAPA. Results. Recent findings suggest that there is a familial tendency to PFAPA but the level of evidence does not warrant definite conclusions. The absence of a clear monogenic trait indicates a heterogenous, polygenic, or complex inheritance of PFAPA syndrome. As two mutations with a possible functional effect on the inflammasomes (MEFV E148Q and NLRP3 Q703K have been found in several PFAPA cohorts, the role of inflammasome-related genes in PFAPA pathogenesis cannot be excluded. Immunological mechanisms of PFAPA involve an abnormal, IL-1β dependent innate immune response to an environmental trigger, which leads to Th1-driven inflammation expressed by recruitment of T-cells to the periphery.

    2015-01-01

    The influence of ribs on the train aerodynamic performance was computed using detached eddy simulation (DES), and the transient iteration was solved by the dual-time step lower-upper symmetric Gauss-Seidel (LU-SGS) method. The results show that the ribs installed on the roof have a great effect on the train aerodynamic performance. Compared with trains without ribs, the lift force coefficient of the train with convex ribs changes from negative to positive, while the side force coefficient increases by 110% and 88%, respectively. Due to the combined effect of the lift force and side force, the overturning moment of the train with convex ribs and cutting ribs increases by 140% and 106%, respectively. There is larger negative pressure on the roof of the train without ribs than that with ribs. The ribs on the train would disturb the flow structure and contribute to the air separation, so the separation starts from the roof, while there is no air separation on the roof of the train without ribs. The ribs can also slow down the flow speed above the roof and make the air easily sucked back to the train surface. The vortices at the leeward side of the train without ribs are small and messy compared with those of the train with convex or cutting ribs.

    Saethre-Chotzen syndrome (SCS) and Muenke-type mutation (MTM) are complex syndromes with craniosynostosis and skeletal anomalies including syndactyly, carpal and tarsal fusions, and cervical spine abnormalities. In this study, we analysed radiographs of the cervical spine, hands and feet of a large patient population with genetically proven SCS and MTM. The aim was to describe the pattern of skeletal anomalies and to determine whether specific features are present that could help differentiate between the two entities. Radiographs of 43 patients (23 males, 20 females) with SCS (n=35) or MTM (n=8) were evaluated. The median age was 8 years (range 1 month-36 years). All radiographs were reviewed by two radiologists. In the hands and feet, a variety of anomalies such as brachyphalangy, clinodactyly, partial syndactyly, partial carpal or tarsal fusion, and cone-shaped epiphyses were noted. Duplicated distal phalanx of the hallux (n=12/35) and triangular deformity of the epiphysis of the distal phalanx of the hallux (n=10/35) were detected in SCS only; calcaneo-cuboid fusion (n=2/35) was detected in MTM only. In the cervical spine, fusion of vertebral bodies and/or the posterior elements occurred only in patients with SCS. Pathognomonic signs for SCS are the triangular shape of the epiphysis and duplicated distal phalanx of the hallux. Calcaneo-cuboid fusion was detected in MTM only. These signs may be helpful in the differentiation of SCS from MTM. (orig.)

    Dystrophic calcinosis in soft tissue occurs in damaged or devitalized tissues in the presence of normal calcium and phosphorous metabolism. It is often noted in subcutaneous tissues in patients with collagen vascular diseases and may involve a relatively localized area or be widespread. A 74-year-old Japanese woman with an overlap of rheumatoid arthritis, Sjögren's syndrome, and systemic sclerosis developed a huge tumor-like mass at the atlanto-axial vertebral joint region that caused severe cervical pain and difficulty in activities of daily living. She also had subcutaneous dystrophic calcification in the soft tissue of the chest wall. Calcinosis associated with systemic sclerosis is a well-recognized phenomenon, but a destructive paraspinal tumor in the cervical spine associated with overlap syndrome is extremely unique. Because calcinosis in spinal locations can be complicated by neurological involvement, patients with progressive symptoms may require surgical intervention. Surgical resection and biological therapy improved this patient's life and activities of daily living. Calcinosis is common in the conditions reviewed here, and different agents have been used for treatment. However, calcinosis management is poorly organized and lacks an accepted classification, systematic studies, and clinical therapeutic trials. The association of calcinosis and collagen vascular diseases is clinically and etiologically important. Although a combination of calcinosis and rheumatoid overlap syndrome is rare, various collagen vascular diseases may occur simultaneously. A perceptive diagnostic approach toward these diseases is critical, and early diagnosis and treatment are needed to prevent dystrophic calcinosis.

    Dystrophic calcinosis in soft tissue occurs in damaged or devitalized tissues in the presence of normal calcium and phosphorous metabolism. It is often noted in subcutaneous tissues in patients with collagen vascular diseases and may involve a relatively localized area or be widespread. A 74-year-old Japanese woman with an overlap of rheumatoid arthritis, Sjögren's syndrome, and systemic sclerosis developed a huge tumor-like mass at the atlanto-axial vertebral joint region that caused severe cervical pain and difficulty in activities of daily living. She also had subcutaneous dystrophic calcification in the soft tissue of the chest wall. Calcinosis associated with systemic sclerosis is a well-recognized phenomenon, but a destructive paraspinal tumor in the cervical spine associated with overlap syndrome is extremely unique. Because calcinosis in spinal locations can be complicated by neurological involvement, patients with progressive symptoms may require surgical intervention. Surgical resection and biological therapy improved this patient's life and activities of daily living. Calcinosis is common in the conditions reviewed here, and different agents have been used for treatment. However, calcinosis management is poorly organized and lacks an accepted classification, systematic studies, and clinical therapeutic trials. The association of calcinosis and collagen vascular diseases is clinically and etiologically important. Although a combination of calcinosis and rheumatoid overlap syndrome is rare, various collagen vascular diseases may occur simultaneously. A perceptive diagnostic approach toward these diseases is critical, and early diagnosis and treatment are needed to prevent dystrophic calcinosis. PMID:24894107

    The present study was designed to estimate the influence of various modalities of therapeutic exercises on the static component of the motor stereotype in 200 patients presenting with cervical myofascial pain syndrome. The study was performed with the use of computed optical topography. The course of therapeutic exercises included 10 sessions of the total duration of 14 days. It is concluded based on the data obtained in this study that remedial gymnastics based on the understanding of the internal body model ("body scheme") with the use of static symmetric exercises is 2.7 times as effective as the traditional approach.

    Ribs and clavicles in posterior-anterior (PA) digital chest radiographs often overlap with lung abnormalities such as nodules, and cause missing of these abnormalities, it is therefore necessary to remove or reduce the ribs in chest radiographs. The purpose of this study was to develop a fully automated algorithm to segment ribs within lung area in digital radiography (DR) for removal of the ribs. The rib segmentation algorithm consists of three steps. Firstly, a radiograph was pre-processed for contrast adjustment and noise removal; second, generalized Hough transform was employed to localize the lower boundary of the ribs. In the third step, a novel bilateral dynamic programming algorithm was used to accurately segment the upper and lower boundaries of ribs simultaneously. The width of the ribs and the smoothness of the rib boundaries were incorporated in the cost function of the bilateral dynamic programming for obtaining consistent results for the upper and lower boundaries. Our database consisted of 93 DR images, including, respectively, 23 and 70 images acquired with a DR system from Shanghai United-Imaging Healthcare Co. and from GE Healthcare Co. The rib localization algorithm achieved a sensitivity of 98.2% with 0.1 false positives per image. The accuracy of the detected ribs was further evaluated subjectively in 3 levels: "1", good; "2", acceptable; "3", poor. The percentages of good, acceptable, and poor segmentation results were 91.1%, 7.2%, and 1.7%, respectively. Our algorithm can obtain good segmentation results for ribs in chest radiography and would be useful for rib reduction in our future study.

  16. Two cases of cervical disc disease with intramedullary pathological changes, which are responsible for their neurological syndromes, on delayed CT myelography

    International Nuclear Information System (INIS)

    We report two cases of cervical disc disease with myelopathy classified as of motor system syndrome type showing small contrast accumulation within the spinal cord on delayed CT myelography. In our two cases, high density spots on delayed CT myelography were bilaterally localized within the spinal cord, and believed represent pathological changes of the spinal cord, such as collection of microcavities or cystic necrosis. In case 1, the high density areas seemed to be localized in the anterior horn and corticospinal tract, and in case 2, they seemed to be localized in the corticospinal tract. The patient in case 1 produced signs and symptoms resembling motor neurone disease and lesion could not be differentiated from the latter. Delayed CT myelography showed that the cause of the upper limb amyotrophy was attributed to an anterior horn disorder and that of pyramidal tract sign to a corticospinal tract disorder. Therefore, we could differentiate the lesion from motor neurone disease on delayed CT myelography in case 1. In conclusion, we emphasize that delayed CT myelography can demonstrate the intramedullary pathological changes in the cervical disc disease and is useful in distinguishing between cervical disc disease simulating motor neurone disease and the latter.

    O' Beirne, T.J.; Shepherd, J.; Gregg, R.C.; De Pledge, D.

    Geomechanics investigations at the Huntly No. 1 West Mine are attempting to define the causes and mechanisms associated with severe rib failures and control problems experienced during drivage of development headings. Rib conditions generally at Huntly can be seen to be closely related to the production of mining induced fractures and the quality and interaction of the general roadway supports. Roadway conditions will certainly improve if rib support is installed much closer to the face line.

    The stabilisation of coal ribs is seen as a key goal in the safe, efficient mining of thick seam friable coals or within zones of high strata pressures. Active rib stabilisation measures are being practised by an increasing number of operators with little or no technical knowledge on the mechanisms causing rib failure, or the remedial measures available. Research work undertaken by Australian Coal Industry Research Laboratories Ltd. (ACIRL) has delineated two distinctly different mechanisms causing rib failure. Various systems have also been developed for combating those mechanisms. Investigations have centred at operating mines, where the mechanisms were first studied; then trials of remedial measures were undertaken. Operators can use the results in this report to define the conditions in their operations and select the most efficient remedial measures. Comments on the use of rib supports for increasing the strength of pillars have been made.

  3. Nozzle airfoil having movable nozzle ribs

    2002-01-01

    A nozzle vane or airfoil structure is provided in which the nozzle ribs are connected to the side walls of the vane or airfoil in such a way that the ribs provide the requisite mechanical support between the concave side and convex side of the airfoil but are not locked in the radial direction of the assembly, longitudinally of the airfoil. The ribs may be bi-cast onto a preformed airfoil side wall structure or fastened to the airfoil by an interlocking slide connection and/or welding. By attaching the nozzle ribs to the nozzle airfoil metal in such a way that allows play longitudinally of the airfoil, the temperature difference induced radial thermal stresses at the nozzle airfoil/rib joint area are reduced while maintaining proper mechanical support of the nozzle side walls.

    Thirty-eight cervical esophageal mucous diaphragms were discovered in the course of 15,000 high endoscopies carried out over the past 5 years at Dakar General Hospital. Thirty-six of the sufferers were Black Senegalese. The 29 women and 9 men had an average age of 37 years. Dysphagia was diagnosed 29 times, and anemia 22 times. Endoscopic diagnosis readily shows the mucous diaphragm at the level of, or immediately below, KILLIAN's mouth. PLUMMER-VINSON's syndrome affected 16 of these patients. Treatment consists in collapsing the mucous diaphragm by putting the endoscope through it: this happened to 30 of the patients. Endoscopic surveillance is indispensable because of the risk of cancer, but is difficult to perform.

    Gorlin-Goltz syndrome is an uncommon disorder transmitted through autosomal dominant inheritance. This syndrome is characterized by multiple odontogenic keratocysts, along with congenital skeletal anomalies and basal cell carcinomas. A 16-year-old girl was admitted with a complaint of swelling on the lower jaw. She had multiple basal cell nevi on both hands. Multiple lytic bone lesions on radiographs were defined as odontogenic keratocysts following the biopsy. The patient was referred to the Department of Physical Medicine and Rehabilitation for detailed musculoskeletal evaluation. Adam's forward bend test revealed a hump on the right side representing right thoracic scoliosis. Cervical kyphosis, thoracic lordosis and scoliosis, bifid rib and sacral and lumbar spina bifida on plain radiographs led to the diagnosis of Gorlin-Goltz syndrome. Since early diagnosis may provide optimum surveillance for related neoplasms, it is of paramount importance for pediatricians as well as physicians dealing with the musculoskeletal system to be aware of this rare condition.

    Full Text Available Multilevel cervical degenerative disc disease is well known in the cervical spine pathology, with radicular syndromes or cervical myelopathy. One or two level cervical herniated disc is common in adult and multilevel cervical degenerative disc herniation is common in the elderly, with spinal stenosis, and have the same cause: the gradual degeneration of the disc. We report the case of a patient with two level cervical disc herniation (C4 – C5 and C5 – C6 treated by anterior cervical microdiscectomy both levels and fusion at C5 – C6; after five years the patient returned with left C7 radiculopathy and MRI provided the image of a left C6 – C7 disc herniation, he underwent an anterior microsurgical discectomy with rapid relief of symptoms. Three-level cervical herniated disc are rare in adults, and the anterior microdiscectomy with or without fusion solve this pathology.

    Background This review aimed to synthesize and analyze the diagnostic accuracy and the likelihood of providing correct treatment of the syndromic approach Vaginal Discharge Flowchart in managing cervical infections caused by Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT), and vaginal infections caused by Trichomonas vaginalis (TV) and Bacterial vaginosis (BV) and Candida albicans. This review will inform updating the WHO 2003 guidelines on Vaginal Discharge syndromic case management. Methods A systematic review was conducted on published studies from 01-01-2000 to 30-03-2015 in multiple databases. Studies evaluating the diagnostic accuracy and validation of the WHO Vaginal Discharge Flowchart were included. Validation parameters including sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) and the 95% confidence intervals for the different types of the flowchart were taken as outcomes, re-calculated, and analysed using a fixed model meta-analysis for data pooling. The level of agreement between the index and reference test were determined by the Cohen’s Kappa co-efficiency test. Each individual study was assessed on quality using the QUADAS-2 tool. Findings The search yielded 2,845 studies of which 16 met the eligibility criteria for final analysis. The diagnostic performance to identify cervical infections was low and resulted in a high proportion of over and missed treatment. The four flowcharts had a sensitivity between 27.37% in history and risk assessment and 90.13% with microscopy, with the inverse in specificity rates. The treatment performances between the flowcharts were inconsistent. The same applies to the use of vaginal discharge flowchart for treating vaginal infections. For vaginal infections the vaginal discharge flowchart had a good performance in flowchart 3 with 91.68% of sensitivity; 99.97% specificity; 99.93% PPV and 0.02% who missed their treatment and 8.32% of women who were over treated

    paciente con síndrome de Brown-Séquard por hernia de disco cervical.This article presents a case in which Brown-Séquard syndrome resulted from a double level cervical disc herniation. A 40-year-old man without previous history of cervical pathology, presented with insidious right arm and leg paresis associated with associated with decreased pain and thermal sensitivity in the left hemibody after diving which caused indirect trauma of the cervical spine. Magnetic resonance imaging of the cervical spine showed double level disc herniation in C4-C5 and C5-6 with compression of the right half of spinal cord and hyperintensity in T2-weighted images. After a complete decompression of neural structures, a double level interbody fusion was performed. There was partial recovery of neurological status after a long period of physical therapy. Early surgical intervention and prompt rehabilitation are paramount to achieve neurological recovery in patients with Brown-Séquard syndrome resulting from a cervical disc herniation.

    The syndrome of periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) is an autoinflammatory disorder of unknown aetiology. Tonsillectomy may cause a prompt resolution of the syndrome. The aim was to study the histologic and immunological aspects of the palatine tonsils in PFAPA, to help understand the pathophysiology of the syndrome. Tonsils from children with PFAPA (n = 11) and children with tonsillar hypertrophy (n = 16) were evaluated histologically after haematoxylin and eosin staining. The number of different cell types was identified immunohistochemically by cluster of differentiation (CD) markers: CD3 (T cells), CD4 (T helper cells), CD8 (cytotoxic T cells), CD15 (neutrophils), CD20 (B cells), CD45 (all leucocytes), CD57 (NK cells) and CD163 (monocytes and macrophages). Tonsils from children with PFAPA showed reactive lymphoid hyperplasia dominated by well-developed germinal centres with many tingible body macrophages. The histologic findings were unspecific, and a similar morphologic appearance was also found in the tonsils from controls. The number of CD8+ cells in germinal centres differed between children with PFAPA [median 9 cells (quartiles: 5, 15)] and controls [18 cells (12, 33) (P = 0.001)] and between children with PFAPA with (median 14 cells; 9, 16) and without (4 cells; 3, 8) aphthous stomatitis (P = 0.015). For the other cell types, no differences in germinal centres were found between children with PFAPA and controls. In conclusion, a lower number of CD8+ cells were found in germinal centres of tonsils in children with PFAPA compared to controls, which may be a feature linked to the aetiology of the syndrome.

The average follow-up time was half a year. 38 out of 47 patients were cured with cervical nerve block and the curative rate was 80%, but other 42 patients were all cured with cervical nerve block outside vertebral canal and manipulation, the curative rate was 100%. There was a significant difference(P<0.05) in two groups. For head-neck-shoulder pain patients without clear cause and obvious nervous signs, they should be diagnosed as compression syndrome of cervical posterior branch, which related to being compressed of cervical posterior branch at the articular process. It was suggested that cervical nerve block outside vertebral canal with manipulation was a pointed and effective therapeutic method.

  13. Optimizing rib width to height and rib spacing to deck plate thickness ratios in orthotropic decks

    Full Text Available Orthotropic decks are composed of deck plate, ribs, and cross-beams and are frequently used in industry to span long distances, due to their light structures and load carrying capacities. Trapezoidal ribs are broadly preferred as longitudinal stiffeners in design of orthotropic decks. They supply the required stiffness to the orthotropic deck in traffic direction. Trapezoidal ribs are chosen in industrial applications because of their high torsional and buckling rigidity, less material and welding needs. Rib width, height, spacing, thickness of deck plate are important parameters for designing of orthotropic decks. In the scope of this study, rib width to height and rib spacing to deck plate thickness ratios are assessed by means of the stresses developed under different ratios of these parameters. For this purpose a FE-model of orthotropic bridge is generated, which encompasses the entire bridge geometry and conforms to recommendations given in Eurocode 3 Part 2. Afterwards necessary FE-analyses are performed to reveal the stresses developed under different rib width to height and rib spacing to deck plate thickness ratios. Based on the results obtained in this study, recommendations regarding these ratios are provided for orthotropic steel decks occupying trapezoidal ribs.

    2011-02-01

    Full Text Available This paper presents the findings obtained by modeling a Double Pipe Heat Exchanger (DPHE equipped with repeated ribs from the inside for artificial roughing. An analytical procedure was developed to analyze the thermal and hydraulic performance of the DPHE with and without ribbing. The procedure was verified by comparing with experimental reported results and they are in good agreement. Several parameters were investigated in this study including the effect of ribs pitch to height ratios, P/e= 5, 10, 15, and 20, and ribs to hydraulic diameter ratios, e/Dh= 0.0595, 0.0765, and 0.107. These parameters were studied at various operating Reynolds number ranging from 2500 to 150000. Different installation configurations were investigated, too. An enhan-cement of 4 times in the heat transfer in terms of Stanton number was achieved at the expense of 38 times increase of pressure drop across the flow in terms of friction facto values.

    2012-06-01

    Full Text Available The late Gothic construction practice, settled in the Spanish Mediterranean area, is based on predetermined geometric rules and is shown in religious buildings with ribbed vaults. The proportion between the sides of the area to cover, tracing plan of the ribs as a succession of corner bisectors, stereotomy problems and volumetric aspects, are just some of the elements that can describe the complex construction of a ribbed vault. The aim of this paper is to analyze the dimensional information of the late gothic ribbed vaults of Sardinia, in order to define the geometric and proportional rules for a correct drawing, establishing a standard procedure for the collection of measures and the construction of the 3D model of vaults.

  18. Sliding Couette flow in a ribbed annulus

    Moradi, H. V.; Floryan, J. M.

    2016-07-01

    The flow in an annulus driven by the axial movement of one of the cylinders has been studied. The stationary cylinder has been fitted with axisymmetric ribs resulting in the appearance of the centrifugal-force-driven instability which leads to the formation of axial vortices. The critical stability conditions have been determined for a wide range of geometries of practical interest; these conditions include the critical Reynolds number as well as the best vortex packing. It has been shown that a sufficiently large increase of the ribs' wavelength leads to a flow stabilization as the flow becomes nearly rectilinear, thus reducing the strength of the centrifugal force field. It has also been demonstrated that a sufficiently large decrease of the ribs' wavelength similarly results in the flow stabilization as the stream lifts up above the ribs' peaks and becomes more rectilinear. Reduction of the annulus' radius leads to qualitatively different flow responses depending on the position of the moving cylinder. The critical Reynolds number is reduced and the range of the ribs' wave numbers capable of inducing the instability is increased when the outer cylinder drives the flow. The trend is reversed when the inner cylinder drives the flow. Conditions when the ribbed cylinder is unable to induce any instability and, thus, behaves as a hydraulically smooth cylinder have been identified.

  19. Effect of Aspect Ratio, Channel Orientation, Rib Pitch-to-Height Ratio, and Number of Ribbed Walls on Pressure Drop Characteristics in a Rotating Channel with Detached Ribs

    2007-01-01

    Full Text Available The present work involves experimental investigation of the effects of aspect ratio, channel orientation angle, rib pitch-to-height ratio (P/e, and number of ribbed walls on friction factor in orthogonally rotating channel with detached ribs. The ribs are separated from the base wall to provide a small region of flow between the base wall and the ribs. Experiments have been conducted at Reynolds number ranging from 10000–17000 with rotation numbers varying from 0–0.38. Pitch-to-rib height ratios (P/e of 5 and 10 at constant rib height-to-hydraulic diameter ratio (e/D of 0.1 and a clearance ratio (C/e of 0.38 are considered. The rib angle of attack with respect to mainstream flow is 90∘. The channel orientation at which the ribbed wall becomes trailing surface (pressure side on which the Coriolis force acts is considered as the 0∘ orientation angle. For one-wall ribbed case, channel is oriented from 0∘ to 180∘ about its axis in steps of 30∘ to change the orientation angle. For two-wall ribbed case, the orientation angle is changed from 0∘ to 90∘ in steps of 30∘. Friction factors for the detached ribbed channels are compared with the corresponding attached ribbed channel. It is found that in one-wall detached ribbed channel, increase in the friction factor ratio with the orientation angle is lower for rectangular channel compared to that of square channel for both the pitch-to-rib height ratios of 5 and 10 at a given Reynolds number and rotation number. Friction factor ratios of two-wall detached ribbed rectangular channel are comparable with corresponding two-wall detached ribbed square channel both under stationary and rotating conditions.

  20. MRI morphometric characterisation of the paediatric cervical spine and spinal cord in children with MPS IVA (Morquio-Brailsford syndrome).

    Nearly all children with MPS IVA develop skeletal deformities affecting the spine. At the atlanto-axial spine, odontoid hypoplasia occurs. GAG deposition around the dens, leads to peri-odontoid infiltration. Transverse/alar ligament incompetence causes instability. Atlanto-axial instability is associated with cord compression and myelopathy, leading to major morbidity and mortality. Intervention is often required. Does the presence of widened bullet shaped vertebra in platyspondily encroach on the spinal canal and cause spinal stenosis in MPS IVA? So far, there have been no standardised morphometric measurements of the paediatric MPS IVA cervical spine to evaluate whether there is pre-existing spinal stenosis predisposing to compressive myelopathy or whether this is purely an acquired process secondary to instability and compression. This study provides the first radiological quantitative analysis of the cervical spine and spinal cord in a series of affected children. MRI morphometry indicates that the MPS IVA spine is narrower at C1-2 level giving an inverted funnel shape. There is no evidence of a reduction in the Torg ratio (canal-body ratio) in the cervical spine. The spinal canal does not exceed 11 mm at any level, significantly smaller than normal historical cohorts (14 mm). The sagittal diameter and axial surface area of both spinal canal and cord are reduced. C1-2 level cord compression was evident in the canal-cord ratio but the Torg ratio was not predictive of cord compression.

    Nearly all children with MPS IVA develop skeletal deformities affecting the spine. At the atlanto-axial spine, odontoid hypoplasia occurs. GAG deposition around the dens, leads to peri-odontoid infiltration. Transverse/alar ligament incompetence causes instability. Atlanto-axial instability is associated with cord compression and myelopathy, leading to major morbidity and mortality. Intervention is often required. Does the presence of widened bullet shaped vertebra in platyspondily encroach on the spinal canal and cause spinal stenosis in MPS IVA? So far, there have been no standardised morphometric measurements of the paediatric MPS IVA cervical spine to evaluate whether there is pre-existing spinal stenosis predisposing to compressive myelopathy or whether this is purely an acquired process secondary to instability and compression. This study provides the first radiological quantitative analysis of the cervical spine and spinal cord in a series of affected children. MRI morphometry indicates that the MPS IVA spine is narrower at C1-2 level giving an inverted funnel shape. There is no evidence of a reduction in the Torg ratio (canal-body ratio) in the cervical spine. The spinal canal does not exceed 11 mm at any level, significantly smaller than normal historical cohorts (14 mm). The sagittal diameter and axial surface area of both spinal canal and cord are reduced. C1-2 level cord compression was evident in the canal-cord ratio but the Torg ratio was not predictive of cord compression. In MPS IVA the reduction in the space available for the cord (SAC) is multifactorial rather than due to congenital spinal stenosis.

    Full Text Available Introduction: Inflammatory cervical swelling may have several causes. The jugular vein thrombosis is a rare entity, often forgotten. Most frequently arises due to a cervical sepsis by the use of a central venous catheter or intravenous drug abuse (drug addicts. Rarely, is secondary to a hypercoagulability state associated with a visceral carcinoma (Trousseau Syndrome. Material and Methods: The authors present the case of a 65 years old male, who used the ENT Emergency Service due to a painful left cervical swelling with local and systemic inflammatory signs of 3 days duration. Results: An cervical ultrasound suggested a neck abscess. CT was performed and confirmed the ultrasound results. Because of its location in the path of the internal jugular vein, we requested re-evaluation by CT with intravenous contrast and doppler ultrasound, obtaining the diagnosis of thrombosis of the internal jugular vein. Further studies were conduct to clarify the hypercoagulability state, since the patient had no known predisposing factor. Finally the diagnosis of unresectable gastric carcinoma was made. Discussion and Conclusion: The ENT must be aware and be able to understand any cervical imagiologic studies. A deep knowledge of the anatomical imagiología is important for the diagnosis of jugular thrombosis. When we have a case of spontaneous jugular thrombosis, we must look for possible visceral carcinoma.

    Klippel-Feil syndrome (KFS) displays congenital fusion of the cervical vertebrae; it is a relatively common condition and has many associated malformations such as Sprengel's deformity, scoliosis, rib anomalies, congenital defects of the brain or spinal cord, renal anomalies, congenital heart disease, deafness, cleft palate, cranial and facial asymmetry, and enteric cysts. There are various types of cervical fusion observed in KFS. However, fusion of the odontoid process with the atlas is a very rare finding. We report here on a 4-year-old boy with unilateral fusion of a separated odontoid process with the lateral mass of the atlas, and this was associated with a spontaneously closed ventricular septal defect, a small patent ductus arteriosus and a horseshoe kidney.

    Full Text Available Introduction: The goal of this study was to investigate the short-term outcomes in patients older than 60 years with isolated rib fractures and admitted to emergency hospital. Materials and Methods: This study included patients who were 60 years old or more and sustained blunt chest injury and had isolated rib fractures. The following data were obtained from the medical records: age, gender, number of fracture ribs, side of fracture ribs, mechanism and nature of injury, preexisting medical conditions, complications, admission to intensive care unit (ICU, need for mechanical ventilation, length of ICU and hospital stay and mortality. Results: For the study, 39 patients who were 60 years old or more and admitted to the hospital because of isolated rib fractures were enrolled. There were 28 males (71.7% and 11 females (28.3% with mean age of (66.84 ± 4.7 years. No correlation was found between comorbidities and hospital outcomes except in those who were diabetic (P-value = 0.005 and those with chronic lung disease (P-value = 0.006. Pulmonary complications were the most frequent complications encountered in those patients. Pulmonary complications were: lung contusion in 8 patients (20.5% and pulmonary infection in 6 patients (15.8%. Conclusion: Elderly patients sustaining blunt chest trauma had significant morbidity and potential for mortality.

    2014-01-01

    Full Text Available Chondroblastoma is a rare benign cartilaginous tumour accounting for approximately 1% of all bone tumours. It commonly arises from epiphysis of a long bone, particularly the humerus, tibia and femur. Rib is an extremely rare site for this tumour with a few cases reported in the literature. It is commonly seen in children and adults between the ages of 10 - 20 years. Although roentgenographic findings are quite common characteristic of this tumour, it can sometimes be misdiagnosed as giant cell tumour, osteogenic sarcoma and myeloma on histopathology. We report a 26-year-old male patient with situs inversus and chondroblastoma of rib. To the best of our knowledge, this is the first case of chondroblastoma of the rib in a patient of situs inversus. Segmental resection is the treatment of choice. It usually behaves in a benign fashion, but few cases have shown local recurrences and distant metastasis; hence, follow-up of the patient is essential.

  7. Coal rib stabilisation - a new perspective

    1986-01-01

    Coal ribs have been observed to fail in different manners depending primarily on the intensity and direction of natural and induced fracture planes. Various combinations of other factors such as stress levels, drivage dimensions, shape, direction and rate, coal strengths, and the presence of dirt bands also play a role in the final state of the coal rib. Stabilisation of ribs by simple bolts or dowels has not always been successful, and is rarely, if ever, seen to be highly efficient. Alternative support to that presently commercially available is discussed for use in specific circumstances. This paper discusses theoretical and practical aspects of the topic and is intended to give colliery managers and engineers a guide to selecting the most efficient means for their conditions.

    The causes of instability in pillar ribs and floors of certain coal mines have been investigated. For rib stability, structural features such as cleat and mining induced fractures have been highlighted as dominant factors. The relationships of cleat, induced fractures, coal strength, seam dip, stress and roadway profile have been studied and methods of predicting rib performance now exist. Numerous artificial means of supporting coal ribs and floors were trialled and novel supports developed. Investigations into artificially strengthening small pillars by rib support were successful and indicate scope for further work. Investigations into floor stability at one colliery were largely inconclusive. 8 refs.

  10. Factors affecting visualization of posterior rib fractures in abused infants

    International Nuclear Information System (INIS)

    Rib fractures in abused infants commonly occur in the posterior rib arcs. Fractures occurring near the costovertebral articulations are usually identified radiographically only once callus has formed. To assess the factors influencing the visibility of fractures near the costovertical articulations, the authors studied 103 posterior rib fractures occurring in 16 abused infants. Radiologic findings were correlated with CT findings and pathologic material from nine ribs in four patients. The limited visibility of fractures relates to (1) the frequent superimposition of the transverse process over the rib fracture site, (2) a fracture line that crosses at an obliquity to the x-ray beam, and (3) nondisplacement of rib fragments due to preservation of the posterior periosteum. Fresh rib fractures invisible on a frontal projection may be clearly defined on axial CT scans, or on postmortem radiographs. A knowledge of the factors influencing the visibility of these important injuries is useful in planning an appropriate diagnostic evaluation of suspected infant abuse

    McAdams, Timothy R.; Deimel, Jay F.; Ferguson, Jeff; Beamer, Brandon S.; Beaulieu, Christopher F.

    2016-01-01

    Background: Although a recognized and discussed injury, chondral rib fractures in professional American football have not been previously reported in the literature. There currently exists no consensus on how to identify and treat these injuries or the expected return to play for the athlete. Purpose: To present 2 cases of chondral rib injuries in the National Football League (NFL) and discuss the current practice patterns for management of these injuries among the NFL team physicians. Study Design: Case series; Level of evidence, 4. Methods: Two cases of NFL players with chondral rib injuries are presented. A survey regarding work-up and treatment of these injuries was completed by team physicians at the 2014 NFL Combine. Our experience in identifying and treating these injuries is presented in conjunction with a survey of NFL team physicians’ experiences. Results: Two cases of rib chondral injuries were diagnosed by computed tomography (CT) and treated with rest and protective splinting. Return to play was 2 to 4 weeks. NFL Combine survey results show that NFL team physicians see a mean of 4 costal cartilage injuries per 5-year period, or approximately 1 case per year per team. Seventy percent of team physicians use CT scanning and 43% use magnetic resonance imaging for diagnosis of these injuries. An anesthetic block is used acutely in 57% and only electively in subsequent games by 39%. Conclusion: A high index of suspicion is necessary to diagnose chondral rib injuries in American football. CT scan is most commonly used to confirm diagnosis. Return to play can take up to 2 to 4 weeks with a protective device, although anesthetic blocks can be used to potentially expedite return. Clinical Relevance: Chondral rib injuries are common among NFL football players, while there is no literature to support proper diagnosis and treatment of these injuries or expected duration of recovery. These injuries are likely common in other contact sports and levels of

    Many lightweight structures consist of plates being stiffened by ribs. The rib stiffeners can significantly change the vibration field and the radiation behavior of the structure. These type of structures has thus often been studied in the past. However, there is a lack of simplified expressions...... for the sound transmission of these structures. Therefore, simplified expressions for the sound transmission of finite single leaf ribbed plates are derived, using a variational technique based on integral equations of the fluid loaded plate....

    Predictions for the deposition of spherical and cylindrical particles from a ribbed channel flow onto adjacent flow boundaries are obtained using large eddy simulation (LES) under the assumption of one-way coupling. Results indicate that spherical particles tend to accumulate on the vertical rib wall facing the mean-flow direction with little particle deposition onto surfaces immediately downstream of the rib. This preferential deposition is not predicted for cylindrical particles

    Rib stress injuries are uncommonly reported but have been documented among athletes, most notably rowers. There have only been two prior case reports of rib stress injuries in swimmers, both of which were young females. Magnetic resonance (MR) imaging was either not obtained or the imaging characteristics were incompletely described. We present a case of an isolated third rib stress injury in a collegiate male swimmer diagnosed via MR imaging. We briefly discuss the possible etiologies for rib stress injuries, their MR appearance, as well as their treatment. (orig.)

  5. Detection and labeling ribs on expiration chest radiographs

    Typically, inspiration is preferred when xraying the lungs. The x-ray technologist will ask a patient to be still and to take a deep breath and to hold it. This not only reduces the possibility of a blurred image but also enhances the quality of the image since air-filled lungs are easier to see on x-ray film. However, inspiration causes low density in the inner part of lung field. That means that ribs in the inner part of lung field have lower density than the other parts nearer to the border of the lung field. That is why edge detection algorithms often fail to detect ribs. Therefore to make rib edges clear we try to produce an expiration lung field using a 'hemi-elliptical cavity.' Based on the expiration lung field, we extract the rib edges using canny edge detector and a new connectivity method, called '4 way with 10-neighbors connectivity' to detect clavicle and rib edge candidates. Once the edge candidates are formed, our system selects the best candidates using knowledge-based constraints such as a gradient, length and location. The edges can be paired and labeled as superior rib edge and inferior rib edge. Then the system uses the clavicle, which is obtained in a same method for the rib edge detection, as a landmark to label all detected ribs.

    1988-03-01

    A case of chondroblastoma in an 18-year-old female arising from a rib near the costotransverse articulation (presumably from the epiphysis of the articular process) has been described. The destructive pattern noted in the rib, associated with a large soft tissue mass, favored a malignant lesion rather than a benign one. Histologically, this tumor had large cystic and hemorrhagic components, consistent with the diagnosis of a cystic chondroblastoma of a rib. Curiously, this patient, like two others with chondroblastoma in a rib was asymptomatic, and attention to the abnormality was drawn from a routine chest radiography. The patient remains disease-free one and a half-years following surgery.

    A 31-year-old postal worker was diagnosed with bilateral thoracic outlet syndrome and scheduled for the first of two surgeries. The first procedure involved removal of the right first cervical rib, anterior and middle scalenes. On postoperative day 4, he developed shortness of breath. Chest radiograph showed a new pleural effusion on the right. Thoracentesis revealed a yellowish-red thick effusion. Based on the initial look of the fluid it was thought to be a haemorrhagic effusion with a purulent component, further testing revealed that he had developed a chylothorax. The patient was placed on a medium-chain triglyceride diet followed by chest tube drainage. After one day, the chest tube was removed due to minimal drainage, and he was discharged home the next day. Keeping this patient without food, on total parental nutrition, or pursuing surgical intervention was not necessary, as he had an excellent outcome from a very rare surgical complication.

    Full Text Available BACKGROUND: Factors determining the shape of the human rib cage are not completely understood. We aimed to quantify the contribution of anthropometric and COPD-related changes to rib cage variability in adult cigarette smokers. METHODS: Rib cage diameters and areas (calculated from the inner surface of the rib cage in 816 smokers with or without COPD, were evaluated at three anatomical levels using computed tomography (CT. CTs were analyzed with software, which allows quantification of total emphysema (emphysema%. The relationship between rib cage measurements and anthropometric factors, lung function indices, and %emphysema were tested using linear regression models. RESULTS: A model that included gender, age, BMI, emphysema%, forced expiratory volume in one second (FEV1%, and forced vital capacity (FVC% fit best with the rib cage measurements (R(2 = 64% for the rib cage area variation at the lower anatomical level. Gender had the biggest impact on rib cage diameter and area (105.3 cm(2; 95% CI: 111.7 to 98.8 for male lower area. Emphysema% was responsible for an increase in size of upper and middle CT areas (up to 5.4 cm(2; 95% CI: 3.0 to 7.8 for an emphysema increase of 5%. Lower rib cage areas decreased as FVC% decreased (5.1 cm(2; 95% CI: 2.5 to 7.6 for 10 percentage points of FVC variation. CONCLUSIONS: This study demonstrates that simple CT measurements can predict rib cage morphometric variability and also highlight relationships between rib cage morphometry and emphysema.

    Today we can state that in spite of a considerable number of cervical osteochondrosis studies, there is a lack of research devoted to analysis of its course. There is no correlation between initial expert evaluations of cervical osteo-chondrosis cases and further course of pathological process. Goal of the research is to develop system of course prognosis of cervical osteochondrosis taking into account environmental infuence, heredity, living conditions, psychological profle of patient’s personality. Materials and methods. Dynamics of degenerative-dystrophic changes progressing of cervical vertebrae in 236 patients was analyzed. Results. Received data demonstrated that probability of stage I changing to stage II, III and IV depended on patients’ sex, age and type of labour activity, frequent supercooling and stress. Probability of fast progression of cervical osteochondrosis (5-year cycle of stage I changing to stage III and IV was to a great extent associated with heredity, urban living, presence of endocrine system diseases, syndrome of nonspecifc dysplasia of connective tissue and low indices of quality of life. Conclusion. Proposed system allows making prognosis of morphologic changes in spinal cord, and is based on radiation methods of verifcation without taking into consideration dynamics of neurological symptomatology.

In the cases, multiple jaw cysts, pal mar and plantar pittings, bridging of sella, temporoparietal bossing, hypertelorism, cleft palate, and dystopia canthoru m have been observed.

  11. Comparison of Postoperative Pain Relief by Intercostal Block Between Pre-rib Harvest and Post-rib Harvest Groups

    International Nuclear Information System (INIS)

    Objective: To compare intercostal nerve block before and after rib harvest in terms of mean postoperative pain score and mean postoperative tramadol usage. Study Design: Randomized controlled trial. Place and Duration of Study: Department of Plastic Surgery, Mayo Hospital, KEMU, Lahore, from January 2011 to July 2012. Methodology: Patients (n = 120) of either gender with ASA class-I and II requiring autogenous costal cartilage graft were inducted. Patients having history of local anaesthetic hypersensitivity and age 60 years were excluded. Subjects were randomly assigned to pre-rib harvest (group-1) and post-rib harvest (group-2). Local anaesthetic mixture was prepared by adding 10 milliliters 2% lidocaine to 10 milliliters 0.5% bupivacaine to obtain a total 20 ml solution. Group-1 received local anaesthetic infiltration along the proposed incision lines and intercostals block before the rib harvest. Group-2 received the infiltration and block after rib harvest. Postoperative consumption of tramadol and pain scores were measured at 6 and 12 hours postoperatively using VAS. Results: Mean age was 31.43 A +- 10.78 years. The mean pain scores at 6 hours postoperatively were 1.033 A +- 0.609 and 2.4667 A +- 0.812 in pre-rib harvest and post-rib harvest groups respectively (p < 0.0001). The mean pain scores at 12 hours postoperatively were 1.45 A +- 0.565 and 3.65 A +- 0.633 in pre-rib harvest and post-rib harvest groups respectively (p < 0.0001). The mean tramadol used postoperatively in first 24 hours was 169 A +- 29.24 mg and 255 A +- 17.70 mg in prerib harvest and post-rib harvest groups respectively (p < 0.0001). Conclusion: Intercostal block administered before rib harvest as preemptive strategy result in decreased postoperative pain scores and narcotic use. (author)

    The purpose of this study is to describe the rib changes seen in patients with brochopulmonary dysplasia (BPD). Serial chest radiographs of nine premature infants with BPD who showed diffuse rib enlargement were reviewed for hyperinflation, which was compared with the observed degree of rib enlargement. Vibrator chest physiotherapy was performed in all cases, and five infants underwent conventional ventilation plus high frequency oscillatory ventilation therapy. Their calcium level was normal whereas alkaline phosphatase and phosphate levels were high. In all infants except one, liver enzyme levels were normal. For the treatment of patent ductus arteriosus, infection, and BPD, medications including indomethacin, antibiotics, and dexamethasone were administered. Vitamin D was given to all patients with total parenteral nutrition. Rib enlargement was found to be severe (n=3D4), moderate (n=3D3), or mild (n=3D2) with undulating margins or posterior tapering (n=3D2). Hyperinflation was noted in eight patients, in seven of whom it was moderate to severe. Among these seven, rib enlargement was severe (n=3D2), moderate (n=3D3), or mild (n=3D2). In one infant with mild hyperinflation, rib enlargement was severe. Bilateral irregular infiltrates and atelectases were noted in all patients. In BPD patients, rib enlargement may be seen. In order to differentiate this process from systemic bone disease or bony dysplasia, an awareness of the rib changes occurring in patients with BPD may be important. (author)

Serial chest radiographs of nine premature infants with BPD who showed diffuse rib enlargement were reviewed for hyperinflation, which was compared with the observed degree of rib enlargement. Vibrator chest physiotherapy was performed in all cases, and five infants underwent conventional ventilation plus high frequency oscillatory ventilation therapy. Their calcium level was normal whereas alkaline phosphatase and phosphate levels were high. In all infants except one, liver enzyme levels were normal. For the treatment of patent ductus arteriosus, infection, and BPD, medications including indomethacin, antibiotics, and dexamethasone were administered. Vitamin D was given to all patients with total parenteral nutrition. Rib enlargement was found to be severe (n=3D4), moderate (n=3D3), or mild (n=3D2) with undulating margins or posterior tapering (n=3D2). Hyperinflation was noted in eight patients, in seven of whom it was moderate to severe. Among these seven, rib enlargement was severe (n=3D2), moderate (n=3D3), or mild (n=3D2). In one infant with mild hyperinflation, rib enlargement was severe. Bilateral irregular infiltrates and atelectases were noted in all patients. In BPD patients, rib enlargement may be seen. In order to differentiate this process from systemic bone disease or bony dysplasia, an awareness of the rib changes occurring in patients with BPD may be important. (author)

  14. NUMERICAL INVESTIGATION ON FLOW CHARACTERISTICS IN RIBBED BEND

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    Previous research[1]by the author has proved that ribbed bend technology is a simple and efficient anti-erosion method. The present paper is a further study to unveil the mechanism of the technology by using numerical method. The flow characteristics in ribbed bend were studied. A k-ε turbulence model was used and the simulations were carried out in the body-fitted coordinates. This procedure was confirmed to be credible by showing the satisfactory agreement between the predications and experimental results. It is concluded that the character of the longitudinal flow in ribbed bend especially in the concave parts between ribs has a beneficial effect on increasing the anti-erosion ability of ribbed bend but the secondary flow will have little effect on determining the particle trajectory.

    Full Text Available Examined bones were obtained from eight adult African giant rats, Cricetomys gambianus Waterhouse. Animals used had an average body mass of 730.00±41.91 gm and body length of 67.20±0.05 cm. The vertebral formula was found to be C7, T13, L6, S4, Ca31–36. The lowest and highest points of the cervicothoracic curvature were at C5 and T2, respectively. The spinous process of the axis was the largest in the cervical group while others were sharp and pointed. The greatest diameter of the vertebral canal was at the atlas (0.8 cm and the lowest at the caudal sacral bones (2 mm. The diameter of the vertebral foramen was the largest at C1 and the smallest at the S4; the foramina were negligibly indistinct caudal to the sacral vertebrae. There were 13 pairs of ribs. The first seven pairs were sternal, and six pairs were asternal of which the last 2-3 pairs were floating ribs. The sternum was composed of deltoid-shaped manubrium sterni, four sternebrae, and a slender processus xiphoideus. No sex-related differences were observed. The vertebral column is adapted for strong muscular attachment and actions helping the rodent suited for speed, agility, dexterity, and strength which might enable it to overpower prey and escape predation.

    Cervical radiculopathy is a common cause of pain in the arm. It is caused by nerve root compression in the neck, as a consequence of a herniated disc, or spondyliotic foraminal stenosis. It causes severe pain, especially during the first few weeks, and paraesthesias in the forearm and hand. Patients also suffer from neck pain and loss of strength in the relevant arm. The arm pain can be exacerbated by certain movements of the head; these should be avoided as much as possible. Diagnosis can be made on the basis of history and physical examination. The pain generally disappears without active patient treatment. A semi-rigid cervical collar is recommended to accelerate pain relief. In cases of persistent pain, surgery will be considered. In such cases an MRI should be performed to show the cause and level of nerve root compression. PMID:26185991

    Full Text Available Introduction: Robinow syndrome is characterized by dwarfism demonstrating short-limbed extremities, vertebral malsegmentation/malformation (hemivertebra, costal dysplasia, genital hypoplasia, and fetal facial appearance (wide and prominent forehead, hypertelorism, small and wide nose, molar hypoplasia, and retrognathia. It is a rare genetic disease which may present with either mild autosomal dominant form or severe recessive form. Vertebral and costal abnormalities are common diagnostic signs that may be severe. The disease presents with kyphoscoliosis and chest abnormalities along with thoracic vertebral fusion and hemivertebral appearance. Ribs may demonstrate fusion. Based on those involvements, the disease can be categorized as spondylothoracic, spondylocostal, ischiovertebral dysplasia, and cervicofaciothoracic syndrome.Diagnosis is established by the help of clinical characteristics. Radiography might contribute to the diagnosis by revealing changes in the skeletal system. Case Report: A three-year-old male patient presented with operated left undescendent testis and buried penis. On physical examination, he also had a dysmorphic face characterized by macrocephaly, hypertelorism, prominent eyes, a flattened nasal bridge, triangular-fish mouth, gingival hypertrophy and left hand clinodactyly. Radiographic examination documented mesomelic shortening of the radius-ulna, malsegmentation of the thoracal spine and the ribs fusion.Conclusion: Robinow syndrome is a rare syndrome which can be diagnosed by typical facial appearance and radiologic findings.

    Full Text Available Abstract Background Spinal cord compression and associate neurological impairment is rare in patients with scoliosis and neurofibromatosis. Common reasons are vertebral subluxation, dislocation, angulation and tumorous lesions around the spinal canal. Only twelve cases of intraspinal rib dislocation have been reported in the literature. The aim of this report is to present a case of rib penetration through neural foramen at the apex of a scoliotic curve in neurofibromatosis and to introduce a new clinical sign for its detection. Methods A 13-year-old girl was evaluated for progressive left thoracic kyphoscoliotic curve due to a type I neurofibromatosis. Clinical examination revealed multiple large thoracic and abdominal "cafe-au-lait" spots, neurological impairment of the lower limbs and the presence of a thoracic gibbous that was painful to pressure at the level of the left eighth rib (Painful Rib Hump. CT-scan showed detachment and translocation of the cephalic end of the left eighth rib into the adjacent enlarged neural foramen. The M.R.I. examination of the spine showed neither cord abnormality nor neurogenic tumor. Results The patient underwent resection of the intraspinal mobile eighth rib head and posterior spinal instrumentation and was neurologically fully recovered six months postoperatively. Conclusion Spine surgeons should be aware of intraspinal rib displacement in scoliotic curves in neurofibromatosis. Painful rib hump is a valuable diagnostic tool for this rare clinical entity.

    Full Text Available ABSTRACT Background Few studies have explored the effects of stretching techniques on diaphragm and spine kinematics. Objective To determine whether the application of diaphragm stretching resulted in changes in posterior chain muscle kinematics and ribcage and abdominal excursion in healthy subjects. Method Eighty healthy adults were included in this randomized clinical trial. Participants were randomized into two groups: the experimental group, which received a diaphragmatic stretching technique, or the placebo group, which received a sham-ultrasound procedure. The duration of the technique, the position of participants, and the therapist who applied the technique were the same for both treatments. Participant assessment (cervical range of movement, lumbar flexibility, flexibility of the posterior chain, and rib cage and abdominal excursion was performed at baseline and immediately after the intervention by a blinded assessor. Results The mean between-group difference [95% CI] for the ribcage excursion after technique at xiphoid level was 2.48 [0.97 to 3.99], which shows significant differences in this outcome. The remaining between-group analysis showed significant differences in cervical extension, right and left flexion, flexibility of the posterior chain, and ribcage excursion at xiphoid level (p<0.05 in favor of the experimental group. Conclusion Diaphragm stretching generates a significant improvement in cervical extension, right and left cervical flexion, flexibility of the posterior chain, and ribcage excursion at xiphoid level compared to a placebo technique in healthy adults.

    Full Text Available Heating surfaces in power boilers are exposed to very high heat flux. For evaporator protection against overheating, internally helically ribbed tubes are used. The intensification of the heat transfer and the maintenance of the thin water layer in the intercostal space, using ribbed tubes, enables better protection of the power boiler evaporator than smooth pipes. Extended inner surface changes flow and thermal conditions by influencing the linear pressure drop and heat transfer coefficient. This paper presents equations that are used to determine the heat transfer coefficient. The results of total heat transfer, obtained from CFD simulations, for two types of internally ribbed and plain tubes are also presented.

    Neutron halos were discovered through measurements of interaction cross sections and fragmentation cross sections of nuclei near the neutron drip line. Such measurements became possible with the use of radioactive ion beams (RIBs) produced though projectile fragmentations of high-energy heavy-ion collisions. RIBs were invented 30 years ago at the Bevalac facility in Berkeley. In this article, I describe how they were invented and how neutron halos were discovered. What happened at that time was a series of small serendipities guiding us to the present prosperous field of RIB science.

    Cervical vertigo refers to a syndrome with a chief complaint of vertigo arising from cervical verteprae discomfort. In general, cervical vertigo is correlated with but not always caused by cervical spondylopathy,which mainly includes vertebral arterial and sympathetic cervical spondylosis. The vertebral artery insufficiency caused by compression from lateral displacement of the intervertebral dise is very rare, while the sympathetic cervical spondylosis caused by the vertebral instability is much more common. Rigorous criteria have been developed for diagnosis of the latter. Conservative therapy is mainly recommended for treatment of cervical vertigo.%颈性眩晕通常与颈椎病有关,但不一定完全由颈椎病所致.与颈性眩晕有关的主要是椎动脉型和交感型颈椎病.由椎间盘侧突压迫导致的椎动脉供血不足非常罕见,由椎体不稳引起的交感型颈椎病较多,但后者也有其严格的诊断标准.治疗以保守治疗为主.

Moreover, an underlying arteriopathy which could be in part genetically determined, has been suspected. The rule of...

  7. Carpal tunnel syndrome, syndrome of partial thenar atrophy, and W. Russell Brain: a historical perspective.

    Boskovski, Marko T; Thomson, J Grant

    2014-09-01

    This article presents the history of the discovery of compression of the median nerve in the carpal tunnel without an identifiable cause as a distinct clinical entity. By analyzing primary sources, we show that, at the beginning of the twentieth century, physicians described patients with paresthesias and numbness in the hands, most prominent at night, accompanied by bilateral symmetrical atrophy along the radial side of thenar eminence. At the time, the 2 most influential hypotheses regarding etiology were, first, compression of the lower trunk of the brachial plexus by a cervical or first rib, and second, compression of the thenar branch of the median nerve as it passes beneath the anterior annular ligament of the wrist. The condition was named syndrome of partial thenar atrophy and was considered a distinct clinical entity. In 1946, after extensive analysis, neurologist Walter Russell Brain concluded that both sensory and motor symptoms of the syndrome were caused by "compression neuritis" of the median nerve in the carpal tunnel. At his suggestion, surgeon Arthur Dickson Wright performed decompression of the nerve by "an incision of the carpal ligament," with excellent results. Brain presented this work at the Royal Society of Medicine in London in 1946 and published his landmark paper in Lancet the following year. In so doing, he established the basis for the disease we know today as idiopathic carpal tunnel syndrome. Unfortunately, in 1947, Brain did not realize that another "condition" with the same clinical picture but without atrophy of the thenar muscles, known as acroparesthesia at the time, was actually the same disease as syndrome of partial thenar atrophy, but of lesser severity. As a result of Brain's influence, 7 other papers were published by 1950. Between 1946 and 1950, there were at least 10 papers that presented, in total, 31 patients (26 women) who exhibited symptoms of compression of the median nerve without an identifiable cause and underwent

  10. A case report of a patient with Ribbing disease underlines the connections between the skeletal and cardiovascular complications

    2011-07-01

    Full Text Available A 69-year-old woman suffered from Ribbing disease, a hereditary X autosomal dominant disease with multiple sclerosing dysplasias. However, it is less known that the genetic mutation can often induce cardiovascular complications. The patient had a hypertensive cardiopathy and had been treated with percutaneous coronary angioplasty and stenting because of a myocardial infarction. She was seen because of dyspnea and we detected an aneurysm of the ascending thoracic aorta. The patient underwent surgical repair. In Ribbing disease an up-regulation of genes interferes with the production, processing, or formation of collagen type II and XI. These genetic effects are thought to be specific for osteoblasts and are responsible for the skeletal pathology. However, the defective synthesis of collagen can also induce cardiovascular complications which may be similar to those described in patients with type III Ehlers-Danlos syndrome, with type IV Marfan syndrome, and with osteogenesis imperfecta. Rheumatologists who treat patients with Ribbing disease should seek the advice of cardiologists for the occurrence of cardiovascular complications.

    Stress fractures of the first rib on the dominant throwing side are well-described in baseball pitchers; however, lower thoracic rib fractures are not commonly recognized. While common in other sports such as rowing, there is scant literature on these injuries in baseball. Intercostal muscle strains are commonly diagnosed in baseball pitchers and have a nearly identical presentation but also a highly variable healing time. The diagnosis of a rib stress fracture can predict a more protracted recovery. This case series presents two collegiate baseball pitchers on one team during the same season who were originally diagnosed with intercostal muscle strains, which following magnetic resonance imaging (MRI) were found to have actually sustained lower thoracic rib stress fractures. The first sustained a stress fracture of the posterior aspect of the right 8th rib on the dominant arm side, while the second presented with a left-sided 10th rib stress fracture on the nondominant arm side. In both cases, MRI was used to visualize the fractures as plain radiographs are insensitive and commonly negative early in patient presentation. Patients were treated with activity modification, and symptomatic management for 4-6 weeks with a graduated return to throwing and competition by 8-10 weeks. The repetitive high stresses incurred by pitching may cause either dominant or nondominant rib stress fractures and this should be included in the differential diagnosis of thoracic injuries in throwers. It is especially important that athletic trainers and team physicians consider this diagnosis, as rib fractures may have a protracted course and delayed return to play. Additionally, using the appropriate imaging techniques to establish an accurate diagnosis can help inform return-to-play decisions, which have important practical applications in baseball, such as roster management and eligibility.

    2016-05-01

    Silicon rib waveguides enable single-mode (SM) operation even with the combination of multi-micron core dimensions and high refractive index contrast. In such large waveguides the optical mode field is almost completely confined inside the Si core, which leads to small propagation losses and small polarization dependency. The unique SM condition of the rib waveguide also enables the use of an ultra-wide wavelength range, for example from 1.2 to <1.7 μm, without sacrificing either SM operation or low propagation loss. This makes micron-scale Si waveguides particularly well-suited for spectroscopy and extensive wavelength division multiplexing. However, rib waveguides require large bending radii, which lead to large circuit sizes. There are two solutions for this. So-called Euler bends in Si strip waveguides enable low-loss bends down to 1 μm bending radius with less than 0.1 dB/90° loss for both polarizations. Another alternative is a total-internal reflection mirror that can have loss as low as 0.1 dB for both polarizations in either strip or rib waveguides. The excitation of higher order modes in large strip waveguides is avoided by using adiabatic rib-strip converters and low-loss components. With rib and strip waveguides it is possible to reach a unique combination of low loss, extremely small footprint, small polarization dependency, ultra-wide bandwidth and tolerance to high optical powers.

    2010-03-01

    Segmentation of individual ribs and other bone structures in chest CT images is important for anatomical analysis, as the segmented ribs may be used as a baseline reference for locating organs within a chest as well as for identification and measurement of any geometric abnormalities in the bone. In this paper we present a fully automated algorithm to segment the individual ribs from low-dose chest CT scans. The proposed algorithm consists of four main stages. First, all the high-intensity bone structure present in the scan is segmented. Second, the centerline of the spinal canal is identified using a distance transform of the bone segmentation. Then, the seed region for every rib is detected based on the identified centerline, and each rib is grown from the seed region and separated from the corresponding vertebra. This algorithm was evaluated using 115 low-dose chest CT scans from public databases with various slice thicknesses. The algorithm parameters were determined using 5 scans, and remaining 110 scans were used to evaluate the performance of the segmentation algorithm. The outcome of the algorithm was inspected by an author for the correctness of the segmentation. The results indicate that over 98% of the individual ribs were correctly segmented with the proposed algorithm.

    Human papillomavirus (HPV) plays a central rule in uterine cervix carcinogenesis. Other factors direct or indirectly influence the installation of this mechanism in cervical squamous epithelium. Investigations regarding mechanisms of interaction of these factors with viral elements are found in the literature of the last 20 years. The present review article discusses possible co-factors of HPV in the genesis of the squamous carcinoma of uterine cervix, taking into account only the factors whose association with the virus or cervical cancer has been documented by experimental studies, and not based just on clinical or epidemiological data. Among the approached parameters are immunological factors (local and humoral immune response), the association with Acquired Immune Deficiency Syndrome, genetic factors as protein p53 polymorphism, tabagism and the use of oral contraceptives. All these factors interact in variable intensity with oncoproteins and other HPV elements, increasing and facilitating the virus action in host cells, leading to the development of immortalization and carcinogenesis.

    1984-09-01

    The incidence and the sites of rib fractures during open-heart operations through a median sternotomy incision were studied in 36 consecutive patients divided into two groups. In Group 1 (24 patients), a conventional Ankeney retractor was used to expose the heart, and in Group 2 (12 patients), a similar retractor was used but with its uppermost pair of blades removed. Thorough physical examinations and preoperative and postoperative chest roentgenograms were obtained, and postoperative bone scans were done in all patients. No rib fractures were detected on the routine chest roentgenograms in patients in either group. Bone scans, however, showed 44 rib fractures (15 of the first rib, 13 of the second rib, 4 of the third rib, 6 of the fourth rib, 3 of the fifth rib, and 3 of the sixth rib) in 16 patients in Group 1. Six patients in Group 2 had 9 rib fractures (2 of the first rib, 4 of the second rib, and 1 each of the third, fifth, and sixth ribs). None of the patients in Group 2 had brachial plexus injury and neither of the first rib fractures in this group were located posteriorly, whereas 3 patients in Group 1 had both brachial plexus injury and posterior first rib fractures.

Vertebralization of the occipital bone and occipitalization of atlas, subluxation of odontoid process, dysplasia of the occipital bone, dystrophia brevicollis and other anomalies are discussed. Special care is given to the study of basilar impression; its concept, history, incidence, clinical and neurological symptoms, radiological characterization (craniographic, perimyelographic and iodoventriculographic aspects and surgical treatment are reviewed. The authors report five cases of occipito-cervical malformations, which are the first references in Brazilian literature. In case 1 the anomalies (manifestation of occipital vertebra and Arnold-Chiari deformity were disclosed at an operation for cisticercosis of the posterior fossa. In the following four cases invagination of the basilar portion of the occipital bone (basilar impression could be radiologically demonstrated; in case 2 a suboccipital craniectomy and a laminectomy of atlas and axis were performed but the patient died a week later and the necroscopic examination confirmed the neuro-skeletal anomalies. In all cases there were several associated malformations. In case 2 there were occipitalization of the atlas, fusion of the first and second cervical vertebrae, supernumerary rib of the seventh cervical vertebra, supernumerary lumbar vertebra, and Arnold-Chiari deformity; at necropsy it was found a syringomyelic cyst on the cervical cord and a fibrous dural ring over the foramen magnum. Case 3 showed the syndrome of Klippel-Feil, besides supernumerary ribs of the seventh cervical and first dorsal vertebrae, Arnold-Chiari malfotmation and probable aplasia of cell groups in the

    Design of rib support systems in U.S. coal mines is based primarily on local practices and experience. A better understanding of current rib support practices in U.S. coal mines is crucial for developing a sound engineering rib support design tool. The objective of this paper is to analyze the current practices of rib control in U.S. coal mines. Twenty underground coal mines were studied representing various coal basins, coal seams, geology, loading conditions, and rib control strategies. The key findings are:(1) any rib design guideline or tool should take into account external rib support as well as internal bolting;(2) rib bolts on their own cannot contain rib spall, especially in soft ribs subjected to significant load—external rib control devices such as mesh are required in such cases to contain rib sloughing;(3) the majority of the studied mines follow the overburden depth and entry height thresholds recommended by the Program Information Bulletin 11-29 issued by the Mine Safety and Health Administration;(4) potential rib insta-bility occurred when certain geological features prevailed—these include draw slate and/or bone coal near the rib/roof line, claystone partings, and soft coal bench overlain by rock strata;(5) 47%of the stud-ied rib spall was classified as blocky—this could indicate a high potential of rib hazards;and (6) rib injury rates of the studied mines for the last three years emphasize the need for more rib control management for mines operating at overburden depths between 152.4 m and 304.8 m.

    Closed-cell type barrier ribs such as meander, honeycomb, SDR, and waffle types were produced using capillary molding process. Sintering of the ribs revealed that the ribs with asymmetric geometry such as meander and SDR type became distorted severely by the sintering process, but the ribs with symmetric geometry such as honeycomb and waffle type maintained their green state morphology. After sintering, the ribs were coated with green phosphor using osmosis coating process and its luminance characteristics were evaluated. The results indicated that the luminance and its efficiency is improved by using closed-cell type ribs with the new phosphor forming technology.

  4. Why do almost all mammals have seven cervical vertebrae? Developmental constraints, Hox genes, and cancer.

    Science.gov (United States)

    Galis, F

    1999-04-15

    Mammals have seven cervical vertebrae, a number that remains remarkably constant. I propose that the lack of variation is caused by developmental constraints: to wit, changes in Hox gene expression, which lead to changes in the number of cervical vertebrae, are associated with neural problems and with an increased susceptibility to early childhood cancer and stillbirths. In vertebrates, Hox genes are involved in the development of the skeletal axis and the nervous system, among other things. In humans and mice, Hox genes have been shown also to be involved in the normal and abnormal (cancer) proliferation of cell lines; several types of cancer in young children are associated with abnormalities in Hox gene expression and congenital anomalies. In these embryonal cancers the incidence of a cervical rib (a rib on the seventh cervical vertebra, a homeotic transformation of a cervical vertebra towards a thoracic-type vertebra) appears to be increased. The minimal estimate of the selection coefficient acting against these mutations is about 12%. In birds and reptiles variations in the number of cervical vertebrae have frequently occurred and there is often intraspecific variability. A review of the veterinary literature shows that cancer rates appear lower in birds and reptiles than in mammals. The low susceptibility to cancer in these classes probably prevents the deleterious pleiotropic effect of neonatal cancer when changes in cervical vertebral number occur. In mammals there is, thus, a coupling between the development of the axial skeleton and other functions (including the proliferations of cell lines). The coupling of functions is either a conserved trait that is also present in reptiles and birds, but without apparent deleterious effects, or the coupling is new to mammals due to a change in the functioning of Hox genes. The cost of the coupling of functions in mammals appears to be an increased risk for neural problems, neonatal cancer, stillbirths, and a

    The Nevoid Basal Cell Carcinoma Syndrome (NBCCS) is an uncommon disorder caused by a mutation in Patched, tumor suppressor gene. It is mainly characterized by numerous early onset basal cell carcinomas, odontogenic cysts of jaw and skeletal abnormalities. Due to the wide clinical spectrum, treatment and management of its modalities are not standardized and should be individualized and monitored by a multidisciplinary team. We report a typical case in a 30-year-old man with multiple basal cell carcinomas, keratotic pits of palmar creases and bifid ribs, with a history of several corrective surgeries for keratocystic odontogenic tumors, among other lesions characteristic of the syndrome.

    A total of 112 operations were performed in 87 patients with a cervicobrachial syndrome, 25 with bilateral lesions, over a period of 8 years. Surgery was reserved for severe or complicated cases. Presenting signs were complex and intricated in 53 p. cent of cases, with neurological lesions predominating. Absence of radial pulse after 90 degrees abduction of the arm, present in 87 p. cent of patients, is not a specific diagnostic test as positive results are obtained in over one-third of a normal population. Electromyography confirmed clinical lesions of the brachial plexus in only one out of 8 cases. A more precise and more sensitive procedure for electromyographic exploration of the plexus was therefore established. Dynamic arteriography of the upper limbs was not conducted routinely (70 p. cent of cases), but was reserved for arterial, neuro-arterial, and arterial and venous forms. The axillary approach was used exclusively (94 times), between 1974 and 1980. However, the frequency of postoperative complications (10 p. cent), and the high level of poor or incomplete results (19.5 p. cent) led to the reestablishment of the supraclavicular route of approach. The latter is used preferentially in neurological forms (57 p. cent of cases in this series) in cases requiring correction of an arterial lesion (aneurysm, ulcerated plaque), or when a cervical rib or apophysomegalia of the 7th cervical vertebra is associated.

  8. Cervical spine injuries in the pediatric and adolescent athlete.

    Injuries of the cervical spine in the pediatric and adolescent athlete are less common than other musculoskeletal injuries. Although many of these injuries are relatively minor, serious and potentially unstable or progressive spinal injury must be excluded. Important anatomic differences between the child younger than 10 years and older children and adolescents influence the types of injuries sustained and make assessment of the child's cervical spine sometimes difficult for practitioners accustomed to treating adolescent and adult athletes. Stable soft-tissue injuries of the cervical spine are the most common injuries that occur in all athletes. These injuries are responsive to symptomatic treatment and aggressive rehabilitation. Stingers are injuries of the brachial plexus and upper cervical roots that result from stretching or compressive forces associated with collision sports. Rapid return of sensory and motor dysfunction of a single upper extremity characterizes this entity; long-term disability is rare. Cervical cord neurapraxia (CCN) with transient quadriplegia is most commonly seen in football players. Most athletes fully recover. Cervical canal stenosis as defined by a Pavlov/Torg ratio of less than or equal to 0.8 is predictive of recurrent CCN. Young athletes sustain CCN secondary to hypermobility of the immature cervical spine. Return to play after these injuries is controversial. The athlete with Down syndrome and potential cervical hypermobility requires a careful cervical and neurologic evaluation prior to clearance for participation in sports. PMID:16958497

    Full Text Available Binkley and Johnson first reported this syndrome in 1951. But it was in 1960, Gorlin-Goltz established the association of basal cell epithelioma, jaw cyst and bifid ribs, a combination which is now frequently known as Gorlin-Goltz syndrome as well as Nevoid Basal Cell Carcinoma Syndrome (NBCCS. NBCCS is inherited as an autosomal dominant trait with high penetrance and variable expressivity. NBCCS is characterized by variety of cutaneous, dental, osseous, opthalmic, neurologic and sexual abnormalities. One such case of Gorlin-Goltz syndrome is reported here with good illustrations.

  10. Rib osteomyelitis in children. Early radiologic and ultrasonic findings

    International Nuclear Information System (INIS)

    The earliest radiographic changes of osteomyelitis in the long bones is deep-seated edema manifesting as soft tissue swelling and obliteration of the intermuscular planes adjacent to the affected bone. Similarly, the early change of rib osteomyelitis is pericostal edema demonstrated by soft tissue swelling of the thoracic wall accompanied by an adjacent inward pleural displacement. In both osteomyelitis of the rib and the long bones, the bony changes will appear 1-2 weeks later. Pericostal edema can be readily diagnosed by ultrasound scan. Pericostal edema, although non specific and can occur in other conditions, yet it is a strong warning sign, set wihin the overall clinical picture of osteomyelitis. (orig.)

    Newts have the remarkable capability of organ/tissue regeneration, and have been used as a unique experimental model for regenerative biology. The Iberian ribbed newt (Pleurodeles waltl) is suitable as a model animal. We have established methods for artificial insemination and efficient transgenesis using P. waltl newts. In addition to the transgenic technique, development of TALENs enables targeting mutagenesis in the newts. We have reported that TALENs efficiently disrupted targeted genes in newt embryos. In this chapter, we introduce a protocol for TALEN-mediated gene targeting in Iberian ribbed newts. PMID:26443218

    1988-01-01

    An opera singer, who "made her living with her diaphragm", developed a post-traumatic unilateral radiculopathy due to cervical disc lesions, C3 to C6. During one year of severe neck and left arm pain she gradually lost the ability to sing difficult operatic passages which brought an end to her music career. Following a three level anterior cervical decompression and fusion, the neck and arm pain was immediately relieved. One week later her voice and singing ability returned to its full strength and power permitting her to resume her activities as a vocalist. The diagnosis of paresis of the left hemi-diaphragm as part of the cervical disc syndrome was implied by postoperative retrospective inference.

    Boneless beef rib eye roasts were surface inoculated on the fat side with ca. 5.7 log CFU/g of a five-strain cocktail of Salmonella for subsequent searing, cooking, and warm holding using preparation methods practiced by restaurants surveyed in a medium-size Midwestern city. A portion of the inoculated roasts was then passed once through a mechanical blade tenderizer. For both intact and nonintact roasts, searing for 15 min at 260°C resulted in reductions in Salmonella populations of ca. 0.3 to 1.3 log CFU/g. For intact (nontenderized) rib eye roasts, cooking to internal temperatures of 37.8 or 48.9°C resulted in additional reductions of ca. 3.4 log CFU/g. For tenderized (nonintact) rib eye roasts, cooking to internal temperatures of 37.8 or 48.9°C resulted in additional reductions of ca. 3.1 or 3.4 log CFU/g, respectively. Pathogen populations remained relatively unchanged for intact roasts cooked to 37.8 or 48.9°C and for nonintact roasts cooked to 48.9°C when held at 60.0°C for up to 8 h. In contrast, pathogen populations increased ca. 2.0 log CFU/g in nonintact rib eye cooked to 37.8°C when held at 60.0°C for 8 h. Thus, cooking at low temperatures and extended holding at relatively low temperatures as evaluated herein may pose a food safety risk to consumers in terms of inadequate lethality and/or subsequent outgrowth of Salmonella, especially if nonintact rib eye is used in the preparation of prime rib, if on occasion appreciable populations of Salmonella are present in or on the meat, and/or if the meat is not cooked adequately throughout.

    We present nuclear physics programs based on the planned experiments using rare isotope beams (RIBs) for the future Korean Rare Isotope Beams Accelerator facility(KRIA). This ambitious facility has both an Isotope Separation On Line (ISOL) and fragmentation capability for producing RIBs and accelerating beams of wide range mass of nuclides with energies of a few to hundreds MeV per nucleon. Low energy RIBs at Elab = 5 to 20 MeV per nucleon are for the study of nuclear structure and nuclear astrophysics toward and beyond the drip lines while higher energy RIBs produced by in-flight fragmentation with the reaccelerated ions from the ISOL enable to explore the neutron drip lines in intermediate mass regions. The planned programs have goals for investigating internal structures of the exotic nuclei toward and beyond the nucleon drip lines by addressing the following issues: how the shell structure evolves in areas of extreme proton to neutron imbalance; whether the isospin symmetry maintains in isobaric mirror nuclei at and beyond the drip lines; how two-proton radioactivity affects abundances of the elements;what the role of the continuum states including resonant states above proton-decay threshold in exotic nuclei is in astrophysical nuclear reaction processes, and how the nuclear reaction rates triggered by unbound proton-rich nuclei make an effect on rapid proton capture processes in a very hot stellar plasma.

    2016-03-01

    Accurate spine segmentation allows for improved identification and quantitative characterization of abnormalities of the vertebra, such as vertebral fractures. However, in existing automated vertebra segmentation methods on computed tomography (CT) images, leakage into nearby bones such as ribs occurs due to the close proximity of these visibly intense structures in a 3D CT volume. To reduce this error, we propose the use of joint vertebra-rib atlases to improve the segmentation of vertebrae via multi-atlas joint label fusion. Segmentation was performed and evaluated on CTs containing 106 thoracic and lumbar vertebrae from 10 pathological and traumatic spine patients on an individual vertebra level basis. Vertebra atlases produced errors where the segmentation leaked into the ribs. The use of joint vertebra-rib atlases produced a statistically significant increase in the Dice coefficient from 92.5 +/- 3.1% to 93.8 +/- 2.1% for the left and right transverse processes and a decrease in the mean and max surface distance from 0.75 +/- 0.60mm and 8.63 +/- 4.44mm to 0.30 +/- 0.27mm and 3.65 +/- 2.87mm, respectively.

  4. MULTIPLE OSSIFIED COSTAL CARTILAGES FOR 1ST RIB

    2014-12-01

    Full Text Available Costal cartilages are flattened bars of hyaline cartilages. All ribs except the last two, join with the sternum through their respective costal cartilages directly or indirectly. During dissection for 1st MBBS students in the Department of Anatomy, JJMMC, Davangere, variation was found in a male cadaver aged 45 –50 years. Multiple ossified costal cartilages for 1st rib were present on left side. There were 3 costal cartilages connecting 1st rib to manubrium. There were two small intercostal spaces between them. The lower two small costal cartilages fused together to form a common segment which in turn fused with large upper costal cartilage. The large upper costal cartilage forms costochondral joint with 1st rib. All costal cartilages showed features of calcification. The present variation of multiple ossified costal cartilages are due to bifurcation of costal cartilage. It may cause musculoskeletal pain, intercostal nerve entrapment or vascular compression. Awareness of these anomalies are important for radiologists for diagnostic purpose and for surgeons for performing various clinical and surgical procedures.

    Cervical vertebral stenotic myelopathy (CVSM), also known as cervical ataxia or wobbler syndrome, is caused by the narrowing of the medullary canal due to a malformation of the cervical vertebrae, resulting in compression of the spinal cord and neurological alterations such as ataxia, hypermetria, weakness, and abnormal stance. The treatment options can be conservative or surgical, with varied effectiveness. The most appropriate surgical technique in the majority of cases is arthrodesis, prov...

    Gardner syndrome is a familial disease consisting of colonic polyposis, osteomas, and soft tissue tumors. We describe unilateral chest wall anomaly in a 32-year-old man with Gardner syndrome. A chest radiograph showed asymmetric hypertrophy of the right seventh to tenth ribs. CT images showed increased size of the medullary portions of these lesions, but relatively normal thickness of the cortex. Intercostal muscles along the right seventh to tenth ribs were hypertrophied as compared with the contralateral ribs. Both lungs were clear but the volume of right lung showed slightly smaller than left one.

    Since its discovery and initial description in the 1960s, the penetrating lesion to the left ninth rib of the Shanidar 3 Neandertal has been a focus for discussion about interpersonal violence and weapon technology in the Middle Paleolithic. Recent experimental studies using lithic points on animal targets suggest that aspects of weapon system dynamics can be inferred from the form of the bony lesions they produce. Thus, to better understand the circumstances surrounding the traumatic injury suffered by Shanidar 3, we conducted controlled stabbing experiments with replicas of Mousterian and Levallois points directed against the thoraces of pig carcasses. Stabs were conducted under both high and low kinetic energy conditions, in an effort to replicate the usual impact forces associated with thrusting spear vs. long-range projectile weapon systems, respectively. Analysis of the lesions produced in the pig ribs, along with examination of goat ribs subjected primarily to high kinetic energy stabs from an independent experiment, revealed consistent differences in damage patterns between the two conditions. In the case of Shanidar 3, the lack of major involvement of more than one rib, the lack of fracturing of the affected and adjacent ribs, and the lack of bony defects associated with the lesion (such as wastage, hinging, and radiating fracture lines) suggests that the weapon that wounded him was carrying relatively low kinetic energy. While accidental injury or attack with a thrusting spear or knife cannot absolutely be ruled out, the position, angulation, and morphology of the lesion is most consistent with injury by a low-mass, low-kinetic energy projectile weapon. Given the potential temporal overlap of Shanidar 3 with early modern humans in western Asia, and the possibility that the latter were armed with projectile weapon systems, this case carries more than simple paleoforensic interest.

  11. Multimodality imaging of Poland syndrome with dextrocardia and limb anomalies.

    Iyer, Ramesh S; Parisi, Marguerite T

    2012-08-01

    Poland syndrome is a rare disorder featuring unilateral anterior thoracic and upper extremity anomalies. These include hypoplasia of the pectoralis major costosternal head, absent pectoralis minor, breast hypoplasia, and absent upper rib cartilage. Pulmonary hypoplasia may occur secondarily. The postulated etiology is underdevelopment of the subclavian artery. Less than 50 cases of Poland syndrome with dextrocardia have been reported. Rib anomalies cause rightward cardiac displacement in fetal life. This case of left-sided Poland syndrome in a young girl is unique not only because of dextrocardia, but also because the condition preferentially afflicts the right side and males.

    Liovic, Petar; Šutalo, Ilija D; Marasco, Silvana F

    2016-09-01

    A novel concept for rib fixation is presented that involves the use of a bioresorbable polymer intramedullary telescoping splint. Bone cement is used to anchor each end of the splint inside the medullary canal on each side of the fracture site. In this manner, rib fixation is achieved without fixation device protrusion from the rib, making the splint completely intramedullary. Finite element analysis is used to demonstrate that such a splint/cement composite can preserve rib fixation subjected to cough-intensity force loadings. Computational fluid dynamics and porcine rib experiments were used to study the anchor formation process required to complete the fixation. PMID:26733094

    This paper deals with experimental modeling of the unsteady junction flow features in the vicinity of an isoflux heated wall with mounted insulated rectangular ribs representing three distinctive ribbed test geometries. Both flow visualizations and surface temperature distributions show that the blockage effect upstream of the ribs, as well as the presence of complex eddy structures inside the open cavities, significantly affect the heat transfer process. All the configurations indicate degraded heat transfer performance in the area close to the ribs and an enhancement just downstream from the last rib. PMID:12496017

    2010-11-01

    Poland syndrome is a rare congenital condition presentingwith typical features including an absent costosternal head of pectoralis major andipsilateral brachysyndactyly. There are many clinical variations of the syndrome including rib defects, absence of shoulder girdle muscle and breast hypoplasia or agenesis. Dextrocardia is rarely associated with Poland Syndrome with only 22 cases being previously reported in the worldwide literature. Whereas 'classical' Poland syndrome is predominantly right sided, all cases associated with dextrocardia have been left sided. We report a further case of left sided Poland syndrome with dextrocardia which might have important implications for the understanding of the pathogenesis of this unusual condition.

    Radanov, B P; Dvorák, J; Valach, L

    1992-02-01

    Fifty-one patients suffering from soft tissue injury of the cervical spine underwent clinical and psychometric examination. Clinical interview evaluated subjective complaints and formal testing of self-estimated cognitive impairment, divided attention, and speed of information processing. Results indicated at least two different syndromes: 1) the "cervicoencephalic syndrome," characterized by headache, fatigue, dizziness, poor concentration, disturbed accommodation, and impaired adaptation to light intensity; and 2) the "lower cervical spine syndrome," which is accompanied by cervical and cervicobrachial pain. When comparing patients with either of these two syndromes, those suffering from cervicoencephalic syndrome had significantly poorer results when tested for divided attention. Speed of information processing was reduced to a comparable extent in both syndromes. These findings were not related to the length of the post-traumatic interval. Reduced processing of working memory is assumed, which may account for more global cognitive problems as well as secondary neurotic reaction. PMID:1553581

    Cervical cancer is one of the leading causes of cancer and cancer-related deaths among women worldwide. More than 85% of cases and deaths occur in the developing world where the availability of effective screening is limited. In this issue of the journal, Pierce and colleagues (beginning on page 1273) describe a novel technique using a high-resolution microendoscope (HRME) to diagnose cervical dysplasia. This perspective reviews the limitations of existing cervical cancer screening methods currently in use in low-resource settings and the potential for HRME imaging to contribute to cervical cancer prevention in the developing world.

    Full Text Available Thoracic cage is made up of twelve thoracic vertebrae, twelve pairs of ribs and costal cartilages (CC and a sternum. Ribs articulate anteriorly with sternum through CC which are flattened bars of hyaline cartilage considered as unossified anterior part of embryonic cartilaginous ribs. Numerical and structural variations of ribs are well documented. In the present study, we observed both structural and numerical variations of thoracic cage, bilaterally. On both the sides, eleven pair of ribs were present, instead of seven, six true ribs were found and second rib with CC was absent. Second and third CC and third CC of right and third CC of left side were bifid. Cartilaginous bridges were present between various CC on both sides. In the midline xiphoid process was found to be bifid. These variations are of immense help to the physicians, surgeons and radiologists.

    2006-01-01

    An experimental study is conducted to investigate the heat transfer augmentation in developing turbulent flow through a ribbed square duct. The duct is made of 16mm thick bakelite sheet. The bottom surface of the ribbed wall having rib pitch to height ratio of 10 is heated by passing a c current to the heater placed under it. The uniform heating is controlled using a digital temperature controller and a variac. The results of ribbed duct are compared with the results of a smooth duct under the same experimental conditions. It is observed that the heat transfer augmentation in ribbed duct is better than that of the smooth duct. At Re=5.0 × 104 , the mean temperature of air flowing through the ribbed duct increases by 2.45 percent over the smooth duct, whereas in the ribbed duct Nusselt number increases by 15.14 percent than that of the smooth duct with a 6 percent increase in pressure drop.

    Rib cage morphology changes with age and sex are expected to affect thoracic injury mechanisms and tolerance, particularly for vulnerable populations such as pediatrics and the elderly. The size and shape variation of the external geometry of the ribs was characterized for males and females aged 0–100 years. Computed tomography (CT) scans from 339 subjects were analyzed to collect between 2700 and 10 400 homologous landmarks from each rib. Rib landmarks were analyzed using the geometric morphometric technique known as Procrustes superimposition. Age- and sex-specific functions of 3D rib morphology were produced representing the combined size and shape variation and the isolated shape variation. Statistically significant changes in the size and shape variation (P < 0.0001) and shape variation (P < 0.0053) of all 24 ribs were found to occur with age in males and females. Rib geometry, location, and orientation varied according to the rib level. From birth through adolescence, the rib cage experienced an increase in size, a decrease in thoracic kyphosis, and inferior rotation of the ribs relative to the spine within the sagittal plane. From young adulthood into elderly age, the rib cage experienced increased thoracic kyphosis and superior rotation of the ribs relative to the spine within the sagittal plane. The increased roundedness of the rib cage and horizontal angling of the ribs relative to the spine with age influences the biomechanical response of the thorax. With the plane of the rib oriented more horizontally, loading applied in the anterior-posterior direction will result in increased deformation within the plane of the rib and an increased risk for rib fractures. Thus, morphological changes may be a contributing factor to the increased incidence of rib fractures in the elderly. The morphological functions derived in this study capture substantially more information on thoracic skeleton morphology variation with age and sex than is currently available in

    Full Text Available Abstract Background In primary care, it is often difficult to diagnose cervical myelopathy. However, a delay in treatment could cause irreversible aftereffects. With a brief and effective self-administered questionnaire for cervical myelopathy, cervical myelopathy may be screened more easily and oversight may be avoided. As there is presently no screening tool for cervical myelopathy, the aim of this study was to develop a self-administered questionnaire for the screening of cervical myelopathy. Methods A case-control study was performed with the following two groups at our university hospital from February 2006 to September 2008. Sixty-two patients (48 men, 14 women with cervical myelopathy who underwent operative treatment were included in the myelopathy group. In the control group, 49 patients (20 men, 29 women with symptoms that could be distinguished from those of cervical myelopathy, such as numbness, pain in the upper extremities, and manual clumsiness, were included. The underlying conditions were diagnosed as carpal tunnel syndrome, cubital tunnel syndrome, thoracic outlet syndrome, tarsal tunnel syndrome, diabetes mellitus neuropathy, cervical radiculopathy, and neuralgic amyotrophy. Twenty items for a questionnaire in this study were chosen from the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire, which is a new self-administered questionnaire, as an outcome measure for patients with cervical myelopathy. Data were analyzed by univariate analysis using the chi-square test and by multiple logistic regression analysis. According to the resulting odds ratio, β-coefficients, and p value, items were chosen and assigned a score. Results Eight items were chosen by univariate and multiple logistic regression analyses and assigned a score. The Hosmer-Lemeshow statistic showed p = 0.805. The area under the receiver operation characteristic curve was 0.86. The developed questionnaire had a sensitivity of 93.5% and a

    Rhinoplasty is arguably one of the most challenging procedures a facial plastic surgeon performs. Numerous techniques have been developed since the inception of rhinoplasty to aid in correction of aesthetic and functional issues. Congenital, iatrogenic, and traumatic etiologies can all lead to a crooked nose. Autologous rib or costal cartilage grafting is a powerful tool that can aid the surgeon in successful correction of the crooked nose. PMID:26126219

    An experimental program has been completed which evaluated the effect of a flow obstruction in a heated channel on the onset of flow instability (OBI). The test channel was rectangular (80 {times} 3 mm), heated on one surface, and equipped with view ports. Tests were conducted in a flow controlled mode at heat fluxes of 370 kW/M{sup 2}, and 610 kW/m{sup 2}. Direct comparisons were made between the demand curve minimum for the unobstructed channel and a channel equipped with a 2.07 mm wide rib that was parallel to the flow and in contact with the heated surface. Data at OFI is presented in the nondimensional terms Of Q{sub ratio} (ratio of heat flux applied to heat flux required to achieve saturated liquid conditions at the exit), and the local Stanton number at the channel exit for each channel arrangement. The Q{sub ratio} and Stanton number values for the unobstructed channel and the rib equipped channel are then compared to produce an estimate of the rib effect.

    Directory of Open Access Journals (Sweden)

    Hiroko Kuwabara

    2014-01-01

    Full Text Available Osteosarcoma (OS is a malignant tumor in which osteoid or bone is produced directly by tumor cells. Some OS cells are positive for cytokeratin (CK and epithelial membrane antigen by immunohistochemistry (IHC and this may lead to a misdiagnosis of metastatic carcinoma, particularly when the tumor location is unusual. On the other hand, gastrointestinal metastasis of OS is rare. We present the case of a 67-year-old Japanese man with a small intestinal intussusception due to metastasis of a CK-positive rib OS. The tumor cells were positive for CK, osteopontin and osteonectin by IHC and a diagnosis of a CK-positive chest wall OS metastasizing to the small intestine was considered. Osteoid or bone formation was histologically absent and therefore chest wall OS had to be differentially diagnosed from metastatic carcinoma of unknown origin. A postmortem histological analysis confirmed a rib OS. Awareness of CK-positive OS is important for making a correct diagnosis and for disease management and an immunohistochemical analysis of the tumor for expression of osteopontin and osteonectin may be used to support the diagnosis. In addition, this case shows that rib OS can metastasize to the gastrointestinal tract, albeit rarely, which may induce an intestinal intussusception.

    New fundamental measurements are presented for the transition process in flat plate boundary layers downstream of two-dimensional square ribs. By use of laser Doppler anemometry (LDA) and a large Matched-Index-of-Refraction (MIR) flow system, data for wall-normal fluctuations and Reynolds stresses were obtained in the near wall region to y+<0.1 in addition to the usual mean streamwise velocity component and its fluctuation. By varying velocity and rib height, the experiment investigated the following range of conditions: k+ = 5.5 to 21, 0.3rib. For "large" elements, evolution of turbulent statistics of the viscous layer for a turbulent boundary layer (y+<~30) was rapid even in flows where the mean velocity profile still showed laminar behavior.

    The circulation in microvascularized rib grafts has been compared with that in conventional rib grafts and in those augmented by a direct vascular bundle implantation into the bone grafts. A new experimental model has been designed to correlate vascular perfusion, bone scan patterns, tetracycline labeling, and histological findings in these bone grafts. Posterior microvascularized rib grafts were found to have a circulatory pattern identical to that of the normal rib. Failed microvascularized rib grafts were revascularized more slowly than conventional rib grafts. Vascular bundles implanted into rib grafts remained patent and increased the rate of revascularization. The stripping or preservation of periosteum had no observable effects on the rate or pattern of conventional rib graft revascularization. The circulation in rib grafts was accurately reflected in technetium 99 bone scans, as was the patency of the anastomoses of microvascularized rib grafts and of implanted vascular bundles. In contrast, tetracycline labeling was repeatedly observed in avascular areas of bone grafts and, therefore, is not a reliable indicator of bone graft circulation

    Heat transfer and friction factors are reported for the measurements of turbulent flows in the convergent and divergent square channels with one-sided ribbed wall as well as two opposite in-line ribbed walls. The study covers three different hydraulic diameter ratios between inlet and exit at the test section such as Dho/Dhi = 0.75, 1.0, and 1.33 and Reynolds numbers in the range of 25,000-79,000. The channels, composing of ten isolated copper sections in the length of test section of 1 m, have the hydraulic diameter of 87.5 mm for the straight channel (Dho/Dhi = 1.0); the rib height-to-hydraulic diameter is 0.114; the rib pitch-to-height ratio equals 10. On the contrary to public opinion that the friction factor depends on the portion of the ribbed area, the total friction factor in the two opposite ribbed walls are lower than in the one-sided ribbed wall in the divergent channel of Dho/Dhi = 1.33 because the total pressure, summing positive dynamic and negative static pressures, is acted. The results show that the two opposite ribbed divergent channel of Dho/Dhi = 1.33 provides the best heat transfer enhancement and the two opposite ribbed convergent channel of Dho/Dhi = 0.75 provides the worst friction factor enhancement, and the ribbed divergent channels are generally recommended.

    Tumor-induced osteomalacia ( TIO ) is a rare paraneoplastic syndrome resulting in renal phosphate wasting and decreased bone mineralization. Nonspeciifc symptoms including fatigue, bone pain, and musculoskeletal weakness make the diagnosis elusive and often lead to a delay in treatment. The prognosis of TIO is excellent following complete resection of the neoplasm, which leads to a rapid and complete reversal of all symptoms. If the tumor cannot be detected, treatment relies on supplementation with phosphate and active vitamin D compounds. We report a case of rib tumors presenting a long history of progressively worsening muscular pain and weakness, and limitation in the motion and function of multiple joints. To our knowledge, this is the ifrst case of rib tumor-related hypophosphatemic osteomalacia reported in the literature. Our aim is to make physicians realize that any patient with unexplained muscular weakness and pain must undergo workup for TIO, including serum phosphate measurement, as this is a rare but potentially curable disease.

    Notalgia paresthetica (NP) is a common refractory, sensory, neuropathic syndrome with the hallmark symptom of localized pruritus of the unilateral infrascapular back. It generally is a chronic noncurable condition with periodic remissions and exacerbations. While the dermatologic syndrome may be multifactorial in etiology, a possible association with underlying cervical spine disease should be evaluated for proper treatment. Collaborative multispecialty evaluation by dermatology, radiology, orthopedic surgery, and neurology may be indicated for primary management of this condition. First-line therapy for NP with associated cervical disease may include nondermatologic noninvasive treatments such as spinal manipulation, physical therapy, massage, cervical traction, cervical muscle strengthening, and oral nonsteroidal anti-inflammatory drugs and muscle relaxants. Notalgia paresthetica may in fact be a cutaneous sign of an underlying degenerative cervical spine disease. We report a case of a patient with cervical spinal stenosis that corresponded directly with the clinical findings of NP. PMID:20349681

    Full Text Available The effect of channel orientation and rib pitch-to-height ratio on the pressure drop distribution in a rib-roughened channel is an important issue in turbine blade cooling. The present investigation is a study of the overall pressure drop distribution in a square cross-sectioned channel, with rib turbulators, rotating about an axis normal to the free stream. The ribs are configured in a symmetric arrangement on two opposite surfaces with a rib angle of 90 ∘ to the mainstream flow. The study has been conducted for three Reynolds numbers, namely, 13 000, 17 000, and 22 000 with the rotation number varying from 0– 0.38 . Experiments have been carried out for various rib pitch-to-height ratios ( P/e with a constant rib height-to-hydraulic diameter ratio ( e/D of 0.1 . The test section in which the ribs are placed on the leading and trailing surfaces is considered as the base case ( orientation angle= 0 ∘ , Coriolis force vector normal to the ribbed surfaces. The channel is turned about its axis in steps of 15 ∘ to vary the orientation angle from 0 ∘ to 90 ∘ . The overall pressure drop does not change considerably under conditions of rotation for the base case. However, for the other cases tested, it is observed that the overall pressure drop increases with an increase in the rotation number for a given orientation angle and also increases with an increase in the orientation angle for a given rotation number. This change is attributed to the variation in the separation zone downstream of the ribs due to the presence of the Coriolis force—local pressure drop data is presented which supports this idea. At an orientation angle of 90 ∘ (ribs on the top and bottom surfaces, Coriolis force vector normal to the smooth surfaces, the overall pressure drop is observed to be maximum during rotation. The overall pressure drop for a case with a rib pitch-to-height ratio of 5 on both surfaces is found to be the highest

    A 33-year-old man presented to the emergency department (ED) with chief complaint of chest pain, persisting for approximately one year. Chest X-ray revealed he was missing the right posterior fifth rib. Physical examination showed no surgical scars, and he reported no history of chest trauma. A CT of his chest demonstrated a mass involving the posterior aspect of the right fifth rib, and subsequent biopsy revealed plasma cells. Laboratory results indicated the tumor was a solitary plasmacytoma of the rib. He was referred to oncology and treated with radiation therapy. This case report illustrates an unusual presentation of a solitary plasmacytoma of the rib.

    Heading AbstractBackground. The reported causes of rib fractures in infants are: child abuse, accidental injury, cardiopulmonary resuscitation, bone fragility, birth trauma and severe cough.Objective. To report chest physiotherapy (CPT) as a new cause of rib fractures in five infants.Materials and methods. We retrospectively identified all infants with rib fractures after CPT for bronchiolitis or pneumonia over a 4-year period in two paediatric and one paediatric radiology units in three university hospitals in Paris.Results. Five boys were identified. Their median age was 3 months. None had any other potential cause of rib fractures. The indication for CPT was bronchiolitis in four cases and pneumonia in one. The median number of rib fractures was four (range 1-5). Fractures were located between the 3rd and 8th ribs; they were lateral in four patients and posterior in one; they were unilateral in four patients and bilateral in one. Evolution was favourable in all cases. The prevalence of rib fractures after CPT during the study period was estimated at 1 in 1,000 infants hospitalised for bronchiolitis or pneumonia.Conclusions. CPT should be considered a potential, but very rare cause of rib fractures in infants. It can be of clinical relevance when rib fractures are the only feature suggestive of child abuse. (orig.)

  9. Primary rib tumours in children (report of 27 cases with short literature review)

    International Nuclear Information System (INIS)

    27 cases of primary malignant and benign rib tumours are reported. The most common malignant rib tumour in childhood is Ewing sarcoma (20 cases). Some other rare bone tumours and tumorous conditions (reticulosarcoma, aneurysmal bone cyst, monostotic rib eosinophilic granuloma, osteoid osteoma and lymphangioma) are also described. In the authors' opinion Ewing sarcoma presents with characteristic clinico-radiographic findings in most of the cases. Other monostotic, primary rib tumours and tumorous conditions in childhood - with the exception of exchondroma and enchondroma - rarely show diagnostic radiographic features. 26 refs., 21 figs., 3 tabs

    We have designed a tapered-rib waveguide and numerically studied the generation of supercontinuum using such waveguides. The Air-SF57 glass-SiO(2) waveguide is 3 cm long, with a varying etched depth to manage the total dispersion. Numerical simulations are conducted for input pulses at a wavelength of 1.55 μm with a width of 150 fs and peak power of 5 kW. The proposed waveguide geometry greatly broadens the output spectrum, extending from ∼1 to ∼6  μm, caused by the continuous modification of the phase-matching condition for the generated waves.

  17. Clavicles, interclavicles, gastralia, and sternal ribs in sauropod dinosaurs: new reports from diplodocidae and their morphological, functional and evolutionary implications.

    2013-03-01

    Ossified gastralia, clavicles and sternal ribs are known in a variety of reptilians, including dinosaurs. In sauropods, however, the identity of these bones is controversial. The peculiar shapes of these bones complicate their identification, which led to various differing interpretations in the past. Here we describe different elements from the chest region of diplodocids, found near Shell, Wyoming, USA. Five morphotypes are easily distinguishable: (A) elongated, relatively stout, curved elements with a spatulate and a bifurcate end resemble much the previously reported sauropod clavicles, but might actually represent interclavicles; (B) short, L-shaped elements, mostly preserved as a symmetrical pair, probably are the real clavicles, as indicated by new findings in diplodocids; (C) slender, rod-like bones with rugose ends are highly similar to elements identified as sauropod sternal ribs; (D) curved bones with wide, probably medial ends constitute the fourth morphotype, herein interpreted as gastralia; and (E) irregularly shaped elements, often with extended rugosities, are included into the fifth morphotype, tentatively identified as sternal ribs and/or intercostal elements. To our knowledge, the bones previously interpreted as sauropod clavicles were always found as single bones, which sheds doubt on the validity of their identification. Various lines of evidence presented herein suggest they might actually be interclavicles - which are single elements. This would be the first definitive evidence of interclavicles in dinosauromorphs. Previously supposed interclavicles in the early sauropodomorph Massospondylus or the theropods Oviraptor and Velociraptor were later reinterpreted as clavicles or furculae. Independent from their identification, the existence of the reported bones has both phylogenetic and functional significance. Their presence in non-neosauropod Eusauropoda and Flagellicaudata and probable absence in rebbachisaurs and Titanosauriformes shows a

    Background:The optimal age at which to initiate for auricular reconstruction is controversial.Rib cartilage growth is closely related to age and determines the feasibility and outcomes of auricular reconstruction.We developed a method to guide the timing of auricular reconstruction in children with microtia ranging in age from 5 to 10 years.Methods:Rib cartilage and the healthy ear were assessed using low-dose multi-slice computed tomography.The lengths of the eighth rib cartilage and the helix of the healthy ear (from the helical crus to the joint of the helix and the earlobe) were measured.Surgery was performed when the two lengths were approximately equal.Results:The preoperative eighth rib measurements significantly correlated with the intraoperative measurements (P < 0.05).From 5 to 10 years of age,eighth rib growth was not linear.In 76 (62.8%) of 121 patients,the eighth rib length was approximately equal to the helix length in the healthy ear;satisfactory outcomes were achieved in these patients.In 18 (14.9%) patients,the eighth rib was slightly shorter than the helix,helix fabrication was accomplished by adjusting the length of the helical crus of stent,and satisfactory outcomes were also achieved.Acceptable outcomes were achieved in 17 (14.0%) patients in whom helix fabrication was accomplished by cartilage splicing.In 9 (7.4%) patients with insufficient rib cartilage length,the operation was delayed.In one (0.8%) patient with insufficient rib cartilage length,which left no cartilage for helix splicing,the result was unsatisfactory.Conclusions:Eighth rib cartilage growth is variable.Rib cartilage assessment relative to the healthy ear can guide auricular reconstruction and personalize treatment in young patients with microtia.

    Experimental and numerical investigations have been conducted to study turbulent flow of water and heat transfer characteristics in a rectangular channel with discontinuous crossed ribs and grooves.The tests investigated the overall heat transfer performance and friction factor in ribbed and ribbed-grooved channels with rib angle of 30°.The experimental results show that the overall thermo-hydraulic performance for ribbed-grooved channel is increased by 10%-13.6% when compared to ribbed channel.The investigation on the effects of different rib angles and rib pitches on heat transfer characteristics and friction factor in ribbed-grooved channel was carried out using Fluent with SST(shear-stress transport) k-ω turbulence model.The numerical results indicate that the case for rib angle of 45° shows the best overall thermo-hydraulic performance,about 18%-36% higher than the case for rib angle of 0°.In addition,the flow patterns and local heat transfer characteristics for ribbed and ribbed-grooved channels based on the numerical simulation were also analyzed to reveal the mechanism of heat transfer enhancement.

    Facilities making use of the Isotope Separator On-Line (ISOL) method for the production of Radioactive Ion Beams (RIB) attract interest because they can be used for nuclear structure and reaction studies, astrophysics research and interdisciplinary applications. The ISOL technique is based on the fast release of the nuclear reaction products from the chosen target material together with their ionization into short-lived nuclei beams. Within this context, the SPES (Selective Production of Exotic Species) facility is now under construction in Italy at INFN-LNL (Istituto Nazionale di Fisica Nucleare — Laboratori Nazionali di Legnaro). The SPES facility will produce RIBs mainly from n-rich isotopes obtained by a 40 MeV cyclotron proton beam (200 μA) directly impinging on a uranium carbide multi-foil fission target. The aim of this work is to describe and update, from a comprehensive point of view, the most important results obtained by the analysis of the on-line behavior of the SPES production target assembly. In particular an improved target configuration has been studied by comparing different codes and physics models: the thermal analyses and the isotope production are re-evaluated. Then some consequent radioprotection aspects, which are essential for the installation and operation of the facility, are presented.

    A 3-year-old African hedgehog (Atelerix albiventris) was presented to the Exotic Animal Clinic of the University of Montreal for evaluation of a mass growing on the right thoracic wall. The diagnostic workup, which included helical computed tomography, confirmed the presence of a large mass, originating from the right 7th rib, infiltrating the thoracic wall and cavity. The animal was euthanized due to the poor prognosis. At necropsy, a well-demarcated mass penetrated the thoracic wall and incorporated the 6th to 8th ribs. Cut sections of the tumor were white, glistening, firm, and gritty. Microscopically, it was composed of polyhedral to elongated cells with interspersed trabeculae of osteoid and large areas of coagulative necrosis. On the basis of histopathologic findings, a diagnosis of osteoblastic osteosarcoma was made. To the authors' knowledge, this is the first report of an osteoblastic osteosarcoma on the thoracic wall of an African hedgehog, as well as the first report of the use of helical computed tomography in that species.

AP and lateral Cobb angles that were measured preoperatively and during the last control, SAL, T1-S1, and T1-T12 distances, coronal and sagittal balances were compared. Conclusions: VEPTR may provide a good correction, and we observed a growth in the spine height and SAL following the treatment of congenital deformities. Long-term, multicenter, prospective studies that compare the spinal height, respiratory functions, the severity of the deformity, and the spinal balance are required in order to evaluate the efficacy of VEPTR.

    Full Text Available Nerve tumors arising from the sympathetic chain are uncommon slow-growing tumors and represent a diagnosis challenge. Their malignant degeneration is rare. Definitive pre-operative diagnosis may be difficult as investigations are not usually helpful. We report the case of a 23-year old woman who presented with an asymptomatic solitary left cervical swelling. She was evaluated with sonography and computed tomography. Complete surgical excision of the lesion was carried out and histologic examination revealed a schwannoma. Post-operatively, the patient showed clinical findings of Horner’s syndrome. Pathologic and radiological evaluation, differential diagnosis of this neoplasm and its management are discussed.

    2015-08-01

    Although it is known that in patients with COPD acute hyperinflation determines shortening of the inspiratory muscles, its effects on both diaphragm and rib cage morphology are still to be investigated. In this preliminary study the relationships between hyperinflation, emphysema, diaphragm and rib cage geometry were studied in 5 severe COPD patients and 5 healthy subjects. An automatic software was developed to obtain the 3-D reconstruction of diaphragm and rib cage from CT scans taken at total lung capacity (TLC) and residual volume (RV). Dome surface area (Ado), radius of curvature, length (Ld) and position (referred to xiphoid level) of the diaphragm and antero-posterior (A-P) and transverse (T) diameters of rib cage were calculated at both volumes. Ado and Ld were similar in COPD and controls when compared at similar absolute lung volumes. Radius of curvature was significantly higher in COPD than in controls only at TLC. In COPD, the range of diaphragm position was invariantly below the xiphoid level, while in controls the top of diaphragm dome was always above it. Rib cage diameters were not different at TLC. A-P diameter was greater in COPD than in controls at RV, while T diameters were similar. In conclusion, in severe COPD diaphragm and rib cage geometry is altered at RV. The lower position of diaphragm is associated to smaller A-P but not transversal rib cage diameters, such that rib cage adopts a more circular shape. PMID:26737755

  13. Synostosis of first and second thoracic ribs: Anatomical and radiological assessment

    Directory of Open Access Journals (Sweden)

    Gupta V

    2009-10-01

    Full Text Available An unusual specimen showing synostosis of left sided first and second ribs was encountered during scanning of bones in anatomy department. The ribs were partially fused in the region of their neck and tubercles, and displayed an osseous tunnel. The tunnel measured 1.2 cm in length and was directed anterolaterally. The shaft of first rib imperceptibly blended with that of the second and resulted in obliteration of first intercostal space. The maximum width of this conjoint shaft was 3.6 cm. Superior surface of the rib specimen was marked by a large muscular impression for scalenus medius muscle. The groove for subclavian artery on the superior surface of first rib was prominent. The anterior end of the second rib and a portion of its shaft were separated from the anterior end of first rib by a V-shaped notch. The radiograph of the specimen confirmed the presence of a tunnel between the fused portions of neck and tubercle. Such skeletal abnormalities may be associated with segmentation defects of bony tissues and variations in the disposition of neurovascular structures, thus rendering them vulnerable to compression at the thoracic outlet. The fused ribs affect the chest wall expansion and may result in respiratory complications. Precise knowledge and awareness of such anomalies is important for clinicians, especially for thoracic surgeons and radiologists.

    Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whether cervical cancer will develop. Early detection and treatment of precancerous lesions can prevent progression to cervical cancer. Ident...

    A riboflavin operon(rib operon)derived from Bacillus subtilis 368 was modified on structure and the resulting operons were expressed in various strains of Escherichia coli. The results showed that the optimization of the rib operon and the host strain used for expression are two main factors affecting the riboflavin production. Replacing the promoter l and rfn box of the rib operon with a strong constructive promoter spo l drastically increased the expression of the rib genes. When E. Coli JMl09 was used as the host strain, the highest riboflavin production reached 95.3μg/mL(about eight times higher than that 0f the unmodified rib operon). In addition, when tetracycline(20 μg/mL)was used as the selective pressure, compared with the ampicillin resistant transformants, a higher riboflavin yield Was obtained in tetracycline resistant host strain.

  20. Bone and 67Ga scintigraphy in the evaluation of rib lesions in patients with multiple myeloma

    International Nuclear Information System (INIS)

    Rib lesions in 14 patients with multiple myeloma were evaluated by 99mTc-phosphorous compound bone scintigraphy and 67Ga scintigraphy. In the present study, in order to accurately detect rib lesions in multiple myeloma. bone and 67Ga scintigraphy were performed in 14 patients with multiple myeloma. The patterns of radionuclide accumulation in rib lesions on bone scintigraphy were classified by their grade, type, and site, and the findings were compared with the results of 67Ga scintigraphy. Thus, in cases of multiple myeloma, it was important to consider carefully both the intensity and the design of bone scintigraphy in combination with follow-up study by 67Ga scintigraphy. As a result of such consideration, we found that bone and 67Ga scintigraphy were useful in distinguishing invasive lesions from benign degenerative changes in the rib cage in cases with suspected rib involvement of multiple myeloma.

    Of patients who have undergone lateral approaches to the thoracic spine, surgical site postoperative pain appears to be greater among those who have undergone transection and removal of a rib segment than those who have not. Therefore, techniques that conserve anatomical position and minimize tissue disruption would theoretically result in less pain and a quicker recovery. Herein, we describe a rib-sparing osteoplastic technique used when rib segments need to be displaced in order to create an unobscured corridor to the operative target. Our approach minimizes soft tissue disruption and restores the anatomical function of the rib. Based on our experience, these patients report less pain, mobilize earlier, and are discharged sooner than those who have had rib segments sacrificed as part of a lateral approach to the spine.

    Imaging techniques provide excellent anatomical images of the cervical spine. The choice to use one technique or another will depend on the clinical scenario and on the treatment options. Plain-film X-rays continue to be fundamental, because they make it possible to evaluate the alignment and bone changes; they are also useful for follow-up after treatment. The better contrast resolution provided by magnetic resonance imaging makes it possible to evaluate the soft tissues, including the intervertebral discs, ligaments, bone marrow, and spinal cord. The role of computed tomography in the study of degenerative disease has changed in recent years owing to its great spatial resolution and its capacity to depict osseous components. In this article, we will review the anatomy and biomechanical characteristics of the cervical spine, and then we provide a more detailed discussion of the degenerative diseases that can affect the cervical spine and their clinical management.

    Full Text Available Abstract Ellis-van Creveld syndrome (EVC is a chondral and ectodermal dysplasia characterized by short ribs, polydactyly, growth retardation, and ectodermal and heart defects. It is a rare disease with approximately 150 cases reported worldwide. The exact prevalence is unknown, but the syndrome seems more common among the Amish community. Prenatal abnormalities (that may be detected by ultrasound examination include narrow thorax, shortening of long bones, hexadactyly and cardiac defects. After birth, cardinal features are short stature, short ribs, polydactyly, and dysplastic fingernails and teeth. Heart defects, especially abnormalities of atrial septation, occur in about 60% of cases. Cognitive and motor development is normal. This rare condition is inherited as an autosomal recessive trait with variable expression. Mutations of the EVC1 and EVC2 genes, located in a head to head configuration on chromosome 4p16, have been identified as causative. EVC belongs to the short rib-polydactyly group (SRP and these SRPs, especially type III (Verma-Naumoff syndrome, are discussed in the prenatal differential diagnosis. Postnatally, the essential differential diagnoses include Jeune dystrophy, McKusick-Kaufman syndrome and Weyers syndrome. The management of EVC is multidisciplinary. Management during the neonatal period is mostly symptomatic, involving treatment of the respiratory distress due to narrow chest and heart failure. Orthopedic follow-up is required to manage the bones deformities. Professional dental care should be considered for management of the oral manifestations. Prognosis is linked to the respiratory difficulties in the first months of life due to thoracic narrowness and possible heart defects. Prognosis of the final body height is difficult to predict.

    Full Text Available Chordomas are neoplasms that arise from notochord embryonic remnants, been the sacrococcygeal spine the main site of involvement; the cervical spine site is uncommon and it account for less than 10% of chordomas. Because of their slow growth, the diagnosis is delayed until they reach a large size, despite which they are locally aggressive tumours due to their relation to critical neurovascular structures and present a high rate of local recurrence. Radical surgery is the elective treatment and proton radiotherapy is used when residual tumour tissue and recurrences.Because of the uncommonness of this pathology, we report a case of a patient with cervical chordoma.

    Full Text Available Cervical necrotizing fasciitis is an unusual encounter in the general surgical practice, but is a life-threatening condition requiring early recognition and adequate surgical treatment. We present the case of a 65 year old male patient referred to our department from a General Hospital. Large excisions of both superficial and deep cervical fascia were required together with necrotic skin on a very large surface. Rapid recovery with early sterilization allowed adequate skin grafting with good results. We advocate for aggressive debridment with excision in viable healthy tissue, with no concern for the future reconstruction followe by early grafting of the skin defect.

    The geomochanical and stability design of an underground granite mine located in Canal San Bovo (Trento district, North- eastern Italy) was described. The exploitation of the granite, which is used in the ceramic industry, was carried out by the rooms and rib pillars method. The rooms are 12 m wide while the pillars are 11 m wide and they cross the main discontinuity set of the rock mass in the perpendicular direction. To verify the stability condition of an underground mine, it is necessary to carry out the calcula- tions that are able to check both the local and global stability of the rock mass. In the studied example, this approach has been applied with the development of analytical and numerical parametric analyses and it has permitted to get the best orientation and to design the size of rooms and pillars.

    A 48-year-old man presented with recurrent spontaneous hemothoraces, which ultimately were found to be secondary to a pedunculated costal osteochondroma causing vascular injury. After initially undergoing endovascular coil embolization, he ultimately required segmental rib resection containing the offending lesion for definite treatment. Although a few cases of symptomatic costal osteochondromas have been reported in the literature, as far as we know, no previous reports have provided direct radiologic confirmation of active bleeding or the role of angiographic intervention. In this report, we highlight the importance of CT angiography in establishing a direct link between an osteochondroma and recurrent hemothorax. We also discuss the diagnostic imaging challenges associated with this condition and the use of a multidisciplinary treatment strategy involving both angiographic and operative management. (orig.)

    A systematic analysis of the polymeric Mach-Zehnder rib waveguide is presented based on the calculation and optimization. The simulation is carried out with the Effective Index Method (EIM) and two-dimensional (2-D)Finite Difference Beam Propagation Method (FD-BPM). The large refractive index step between the consecutive polymer layers is reduced by using EIM and thus the precision of the calculation is ensured. The important parameters of the waveguide such as Y-junction angle and the separation gap are discussed and their relationships with the optical power propagation and the loss characteristics are investigated in this paper. The total loss of the optimized structure is 0.258 dB.

    Villard, Pierre-Frédéric; Bourne, Wesley; Bello, Fernando

    Modeling of diaphragm behaviour is of relevance to a number of clinical procedures such as lung cancer radiotherapy and liver access interventions. The heterogeneity in tissue composition of the diaphragm, as well as the various physiological phenomena influencing its behaviour, requires a complex model in order to accurately capture its motion. In this chapter we present a novel methodology based on a heterogenous model composed of mass-spring and tensegrity elements. The physiological boundary conditions have been carefully taken into account and applied to our model. Thus, it incorporates the influence of the rib kinematics, the muscle natural contraction/relaxation and the motion of the sternum. Initial validation results show that the behaviour of the model closely follows that of a real diaphragm.

    A series of short stiffened panel designs which may be applied to a preliminary design assessment of an aircraft wing rib is presented. The computer program PASCO is used as the primary design and analysis tool to assess the structural efficiency and geometry of a tailored corrugated panel, a corrugated panel with a continuous laminate, a hat stiffened panel, a blade stiffened panel, and an unstiffened flat plate. To correct some of the shortcomings in the PASCO analysis when shear is present, a two step iterative process using the computer program VICON is used. The loadings considered include combinations of axial compression, shear, and lateral pressure. The loading ranges considered are broad enough such that the designs presented may be applied to other stiffened panel applications. An assessment is made of laminate variations, increased spacing, and nonoptimum geometric variations, including a beaded panel, on the design of the panels.

    Full Text Available Syringomyelia secondary to cervical spondylosis is a rare entity to encounter in clinical practice. We discuss the case of a 53-year-old lady who presented with a syringomyelic syndrome and was found to have cervical spondylosis on imaging. Cine-MRI revealed an obstruction of cerebrospinal fluid (CSF flow in the cervical spinal subarachnoid space. Decompression of the same led to clinical and radiological improvement. There is a potential causal association between cervical spondylosis and syringomyelia. MRI CSF flow studies may help in deciding the course of treatment in such cases. A subset of patients with cervical spondylosis and concurrent spinal cord signal intensity changes may show reversal of the same following intervention.

    CrossFit is a high-intensity strength and conditioning program that has gained popularity over the past decade. Potential injuries associated with CrossFit training have been suggested in past reports. We report three cases of cervical carotid dissection that are associated with CrossFit workouts. Patient 1 suffered a distal cervical internal carotid artery (ICA) dissection near the skull base and a small infarct in Wernicke's area. He was placed on anticoagulation and on follow-up has near complete recovery. Patient 2 suffered a proximal cervical ICA dissection that led to arterial occlusion and recurrent middle cerebral artery territory infarcts and significant neurological sequelae. Patient 3 had a skull base ICA dissection that led to a partial Horner's syndrome but no cerebral infarct. While direct causality cannot be proven, intense CrossFit workouts may have led to the ICA dissections in these patients.

    1996-11-01

    In analysis of the cervical and cervicobrachial syndrome with or without signs of compression of the nerve root or spinal cord, functional assessment of the cervical spine is of great importance. Comparisons between actively performed and passively induced motion can be verified by using standardized computer-assisted assessment allowing precise documentation of the range of motion and coupled motion. The age-related normal values should be considered. The neurological assessment includes not only the cranial nerves and upper extremities but also lower extremities to avoid overlooking the signs of cervical myelopathy. In patients with compression of nerve roots or the spinal cord neurophysiology might be helpful in identifying or verifying compression. In patients with suspected myelopathy sensory evoked potentials will allow assessment of the function of the ascending spinal pathways and motor evoked potentials, assessment of the function of the descending cortical spinal pathways.

    Thoracic outlet syndrome (TOS) is a condition arising from compression of the subclavian vessels and/or brachial plexus as the structures travel from the thoracic outlet to the axilla. Despite the significant pathology associated with TOS, there remains some general disagreement among experts on the specific anatomy, etiology, and pathophysiology of the condition, presumably because of the wide variation in symptoms that manifest in presenting patients, and because of lack of a definitive gold standard for diagnosis. Symptoms associated with TOS have traditionally been divided into vascular and neurogenic categories, a distinction based on the underlying structure(s) implicated. Of the two, neurogenic TOS (nTOS) is more common, and typically presents as compression of the brachial plexus; primarily, but not exclusively, involving its lower trunk. Vascular TOS (vTOS) usually involves compression of the vessel, most commonly the subclavian artery or vein, or is secondary to thrombus formation in the venous vasculature. Any anatomical anomaly in the thoracic outlet has the potential to predispose a patient to TOS. Common anomalies include variations in the insertion of the anterior scalene muscle (ASM) or scalenus minimus muscle, the presence of a cervical rib or of fibrous and muscular bands, variations in insertion of pectoralis minor, and the presence of neurovascular structures, which follow an atypical course. A common diagnostic technique for vTOS is duplex imaging, which has generally replaced more invasive angiographic techniques. In cases of suspected nTOS, electrophysiological nerve studies and ASM blocks provide guidance when screening for patients likely to benefit from surgical decompression of TOS. Surgeons generally agree that the transaxillary approach allows the greatest field of view for first rib excision to relieve compressed vessels. Alternatively, a supraclavicular approach is favored for scalenotomies when the ASM impinges on surrounding

    2016-06-01

    This paper presents an analytical investigation on physical mechanisms of actively controlling sound transmission through a rib stiffened double-panel structure using point source in the cavity. The combined modal expansion and vibro-acoustic coupling methods are applied to establish the theoretical model of such active structure. Under the condition of minimizing radiated power of the radiating ribbed plate, the physical mechanisms are interpreted in detail from the point of view of modal couplings similar as that used in existed literatures. Results obtained demonstrate that the rule of sound energy transmission and the physical mechanisms for the rib stiffened double-panel structure are all changed, and affected by the coupling effects of the rib when compared with the analytical results obtained for unribbed double-panel case. By taking the coupling effects of the rib into considerations, the cavity modal suppression and rearrangement mechanisms obtained in existed investigations are modified and supplemented for the ribbed plate case, which gives a clear interpretation for the physical nature involved in the active rib stiffened double-panel structure.

  2. Fundamentally excited flow past a surface-mounted rib. Part I: Turbulent structure characterisation

    Different data analysis techniques for characterisation of the turbulent flow past a surface-mounted rib are reviewed. Deficiencies of the existing techniques are explained and modified techniques for determination of coherent structure magnitude and phase jitter are suggested. The effect of fundamental excitation on the flow is studied by using these turbulent signal analysis techniques. The appropriate length scale for characterizing the large-scale structures present in the reattaching shear layer of the surface-mounted rib is found to be the momentum thickness at the downstream edge of the rib, and the corresponding Strouhal number is 0.013. This is in contrast to a rib in the free stream, where the rib height is the correct scaling parameter. The post reattachment region is observed to be dominated by large-scale structures contrary to the traditional belief that large eddies break into small scales at the reattachment location. Low magnitude of phase jitter in the near field region is observed, indicating coherence of the flow structures. Phase decorrelation begins to occur beyond three rib heights from the downstream edge of the rib. From the quadrant analysis results, the outer edge of the shear layer is observed to be dominated by large-scale ejection motions.

    To assess a radiologist's detection rate of rib fractures in trauma CT when reading curved planar reformats (CPRs) of the ribs compared to reading standard MPRs. Two hundred and twenty trauma CTs (146 males, 74 females) were retrospectively subjected to a software algorithm to generate CPRs of the ribs. Patients were split into two equal groups. Sixteen patients were excluded due to insufficient segmentation, leaving 107 patients in group A and 97 patients in group B. Two radiologists independently evaluated group A using CPRs and group B using standard MPRs. Two different radiologists reviewed both groups with the inverse methods setting. Results were compared to a standard of reference created by two senior radiologists. The reference standard identified 361 rib fractures in 61 patients. Reading CPRs showed a significantly higher overall sensitivity (P < 0.001) for fracture detection than reading standard MPRs, with 80.9 % (584/722) and 71.5 % (516/722), respectively. Mean reading time was significantly shorter for CPRs (31.3 s) compared to standard MPRs (60.7 s; P < 0.001). Using CPRs for the detection of rib fractures accelerates the reading of trauma patient chest CTs, while offering an increased overall sensitivity compared to conventional standard MPRs. (orig.)

The micro-ribs were fabricated on the sidewalls of microfluidic channels by a surface-micromachining micro-electro-mechanical system (MEMS process and used as turbulators to improve the heat transfer rate of the microfluidic heat sink. The results indicate that the utilizing of micro-ribs provides a better heat transfer rate, but also increases the pressure drop penalty for microchannels. Furthermore, the heat transfer and friction characteristics of the microchannels are strongly affected by the rib shape. In comparison, the triangular ribbed microchannel possesses the highest Nusselt number and friction factor among the three rib types.

    Background. There is a lack of scientific evidence in the literature on the involvement of the cervical spine in mTBI; however, its involvement is clinically accepted. Objective. This paper reviews evidence for the involvement of the cervical spine in mTBI symptoms, the mechanisms of injury, and the efficacy of therapy for cervical spine with concussion-related symptoms. Methods. A keyword search was conducted on PubMed, ICL, SportDiscus, PEDro, CINAHL, and Cochrane Library databases for articles published since 1990. The reference lists of articles meeting the criteria (original data articles, literature reviews, and clinical guidelines) were also searched in the same databases. Results. 4,854 records were screened and 43 articles were retained. Those articles were used to describe different subjects such as mTBI's signs and symptoms, mechanisms of injury, and treatments of the cervical spine. Conclusions. The hypothesis of cervical spine involvement in post-mTBI symptoms and in PCS (postconcussion syndrome) is supported by increasing evidence and is widely accepted clinically. For the management and treatment of mTBIs, few articles were available in the literature, and relevant studies showed interesting results about manual therapy and exercises as efficient tools for health care practitioners.

    Full Text Available Human immunodeficiency virus (HIV-positive patients have a greater prevalence of coinfection with human papillomavirus (HPV is of high oncogenic risk. Indeed, the presence of the virus favours intraepithelial squamous cell lesion progression and may induce cancer. The aim of this study was to evaluate the prevalence of HPV infection, distribution of HPV types and risk factors among HIV-positive patients. Cervical samples from 450 HIV-positive patients were analysed with regard to oncotic cytology, colposcopy and HPV presence and type by means of polymerase chain reaction and sequencing. The results were analysed by comparing demographic data and data relating to HPV and HIV infection. The prevalence of HPV was 47.5%. Among the HPV-positive samples, 59% included viral types of high oncogenic risk. Multivariate analysis showed an association between HPV infection and the presence of cytological alterations (p = 0.003, age greater than or equal to 35 years (p = 0.002, number of partners greater than three (p = 0.002, CD4+ lymphocyte count < 200/mm3 (p = 0.041 and alcohol abuse (p = 0.004. Although high-risk HPV was present in the majority of the lesions studied, the low frequency of HPV 16 (3.3%, low occurrence of cervical lesions and preserved immunological state in most of the HIV-positive patients were factors that may explain the low occurrence of precancerous cervical lesions in this population.

    2013-01-01

    Full Text Available The scapulothoracic articulation is a sliding junction between the deep aspect of the scapula and thoracic rib cage at the levels of ribs 2 through 7. Motion at this articulation is dynamically stabilized by a variety of muscular attachments, allowing for controlled positioning of the glenoid to assist in glenohumeral joint function. A thorough understanding of the complex anatomic relationships, including the various muscles, and bursa, is critical to the evaluation of patients presenting with scapulothoracic disorders. The snapping scapula syndrome is caused by either osseous lesions or scapulothoracic bursitis and can be difficult to recognize and treat. The purpose of this review is to discuss the anatomy of the scapulothoracic articulation with an emphasis on the pathology associated with snapping scapula syndrome.

    Full Text Available Abstract Background Cervical cancer is the first most common cancer in women in sub-Saharan Africa followed by breast cancer. In Ethiopia, the incidence of cervical cancer is high i.e. 35.9 per 100,000 women. Low level of awareness, lack of effective screening programs, overshadowed by other health priorities (such as acquired immune deficiency syndrome, tuberculosis and malaria and insufficient attention to women’s health are the possible factors for the observed higher incidence rate of cervical cancers in the country. Data on knowledge of Ethiopian women regarding cervical cancer is lacking. The aim of this study was to assess the knowledge of women about cervical cancer and associated factors. Methods A community based cross-sectional survey was conducted from April 4-16, 2010 in Gondar town, Northwest Ethiopia. A total of 633 women aged 15 years and above were interviewed using semi-structured questionnaire by 8 trained data collectors and 2 supervisors. SPSS Windows version 15.0 was employed for data entry and analysis. Result Of all the respondents, 495 (78.7% of them had heard about cervical cancer and only 195 (31% of them were knowledgeable about the disease. Conclusion The knowledge of women on cervical cancer was found to be poor. Education about the disease must include information on risk factors, sign and symptoms of cervical cancer.

    2016-06-01

    A 2-D numerical simulation is carried out to investigate the effect of two adiabatic square ribs on laminar flow and heat transfer in an asymmetrically heated channel. The two ribs are symmetrically located on each wall, exactly above the heating zone. The computational procedure is made by solving the unsteady bi-dimensional continuity, momentum and energy equations with the finite volume method. The investigations focused more specifically on the influence of ribs sizes on the flow structure and heat transfer enhancement. The results showed that the variation of ribs sizes significantly alters the heat transfer and fluid flow distribution along the channel, especially in the vicinity of protrusions. Also, the results show that streamlines, isotherms, and the number, sizes and formation of vortex structures inside the channel strongly depend on the size of protrusions. The changes in heat transfer parameters have also been presented.

    Schlieren techniques are valuable tools for the qualitative and quantitative visualizations of flows in a wide range of scientific and engineering disciplines. A large number of schlieren systems have been developed and documented in the literature; majority of applications involve flows of gases, typically air. In this work, a schlieren technique is applied to visualize the buoyancy-induced flow inside vertical ribbed channels using water as convective fluid. The test section consists of a vertical plate made of two thin sheets of chrome-plated copper with a foil heater sandwiched between them; the external sides of the plate are roughened with transverse, square-cross-sectioned ribs. Two parallel vertical walls, smooth and unheated, form with the heated ribbed plate two adjacent, identical and asymmetrically heated, vertical channels. Results include flow schlieren visualizations with colour-band filters, reconstructions of the local heat transfer coefficient distributions along the ribbed surfaces and comparisons with past experiments performed using air as working fluid.

    Rationale of this study was to evaluate whether unfolded rib images enhance time efficiency in detection of rib fractures and time efficiency in patients with acute thoracic trauma. 51 subsequent patients with thoracic trauma underwent 64-slice computed tomography. 1mm thick axial slices were reformatted using a commercially available post-processing software application generating rotatable unfolded rib images. Diagnostic accuracy was evaluated by 3 readers and compared to multiplanar reformations of the original CT images. Reformation and evaluation times were recorded. 116 rib fractures were detected. The multiplanar reformation analysis yielded a sensitivity of 87.9%/93.9%/79.7% with a specificity of 97%/97%/82.2%, whilst the unfolded rib image analysis yielded a sensitivity of 94.8%/94.8%/92.2% and a specificity of 85.2/87.8%/82.4 (p=0.06/0.8/0.04) with high inter-observer agreement (k=0.79-0.85). The mean reading time for the multiplanar reformations was significantly longer (reader 1: 103.7 ± 27.1s/reader 2: 81.8 ± 40.6s/reader 3: 154.3 ± 39.2s) than the evaluation of the unfolded rib images (19.4 ± 4.9s/26.9 ± 15.0s/49.9 ± 18.7s; p<0.01). Concluding, the unfolded rib display reduces reading time for detection of rib fractures in acute thoracic trauma patients significantly and does not compromise the diagnostic accuracy significantly in experienced radiologists. However, unexperienced readers may profit from use of this display. PMID:26226916

  8. Frequency of intrathoracic injuries in children younger than 3 years with rib fractures

    International Nuclear Information System (INIS)

    Research documents that among children admitted to trauma intensive care units the number of rib fractures sustained indicates the child's likelihood of having and severity of intrathoracic injury. This has been misused in court to argue that children with multiple rib fractures who lack intrathoracic injury have abnormal bone fragility rather than inflicted injury. To determine frequency of intrathoracic injuries in children younger than 3 years with rib fractures in cases of child abuse and accidental trauma. We conducted a retrospective review of rib fractures caused by documented abuse or accidents from 2003 to 2010 in children treated at Seattle Children's Hospital and Harborview Medical Center. A senior pediatric radiologist and radiology fellow independently reviewed the imaging. Children with bone demineralization were excluded. Descriptive and simple comparative statistics were used. Seventy-two percent (47/65) of infants and toddlers with rib fractures were abused. Abused children had more rib fractures than accidentally injured children (5.55 vs. 3.11, P = 0.012). However intrathoracic injuries as a whole (55.6% vs. 12.8%, P < 0.001) and individual types of intrathoracic injuries were more common with accidents. Rates of other thoracic cage injuries did not differ substantially (27.8% accidents vs. 12.8% abuse, P = 0.064). Intracranial and intra-abdominal injuries and skull fractures were equally frequent, but other extrathoracic fractures were more common with abuse (70.2% vs. 16.7%, P < 0.001). Abused infants and toddlers have fewer intrathoracic injuries but more rib fractures than accidentally injured peers. This likely reflects different injury mechanics. Lack of intrathoracic injuries in abused children with rib fractures does not imply bone fragility. (orig.)

  9. Rib fractures after reirradiation plus hyperthermia for recurrent breast cancer. Predictive factors

    International Nuclear Information System (INIS)

    Combining reirradiation (reRT) and hyperthermia (HT) has shown high therapeutic value for patients with locoregional recurrent breast cancer (LR). However, additional toxicity of reirradiation (e.g., rib fractures) may occur. The aim of this study is to determine the impact of potential risk factors on the occurrence of rib fractures. From 1982-2005, 234 patients were treated with adjuvant reRT + HT after surgery for LR. ReRT consisted typically of 8 fractions of 4 Gy twice a week, or 12 fractions of 3 Gy four times a week. A total of 118 patients were irradiated with abutted photon and electron fields. In all, 60 patients were irradiated using either one or alternating combinations of abutted AP electron fields. Hyperthermia was given once or twice a week. The 5-year infield local control (LC) rate was 70 %. Rib fractures were detected in 16 of 234 patients (actuarial risk: 7 % at 5 years). All rib fractures occurred in patients treated with a combination of photon and abutted electron fields (p = 0.000); in 15 of 16 patients fractures were located in the abutment regions. The other significant predictive factors for rib fractures were a higher fraction dose (p = 0.040), large RT fields, and treatment before the year 2000. ReRT + HT results in long-term LC. The majority of rib fractures were located in the photon/electron abutment area, emphasizing the disadvantage of field overlap. Large abutted photon/electron fields combined with 4 Gy fractions increase the number of rib fractures in this study group. However, as these factors were highly correlated no relative importance of the individual factors could be estimated. Increasing the number of HT sessions a week does not increase the risk of rib fractures. (orig.)

    Physical abuse of infants at the hand of a parent or carer is a significant and growing issue worldwide. In particular, rib fractures in the absence of major accidental trauma are highly specific for physical abuse. Despite the serious implications of physical abuse in infants, definitive knowledge regarding the hierarchical structure of the immature rib and how this influences the mechanical failure is lacking. Moreover, the diagnosis of physical abuse is often disputed in a legal setting, a...

    Research documents that among children admitted to trauma intensive care units the number of rib fractures sustained indicates the child's likelihood of having and severity of intrathoracic injury. This has been misused in court to argue that children with multiple rib fractures who lack intrathoracic injury have abnormal bone fragility rather than inflicted injury. To determine frequency of intrathoracic injuries in children younger than 3 years with rib fractures in cases of child abuse and accidental trauma. We conducted a retrospective review of rib fractures caused by documented abuse or accidents from 2003 to 2010 in children treated at Seattle Children's Hospital and Harborview Medical Center. A senior pediatric radiologist and radiology fellow independently reviewed the imaging. Children with bone demineralization were excluded. Descriptive and simple comparative statistics were used. Seventy-two percent (47/65) of infants and toddlers with rib fractures were abused. Abused children had more rib fractures than accidentally injured children (5.55 vs. 3.11, P = 0.012). However intrathoracic injuries as a whole (55.6% vs. 12.8%, P < 0.001) and individual types of intrathoracic injuries were more common with accidents. Rates of other thoracic cage injuries did not differ substantially (27.8% accidents vs. 12.8% abuse, P = 0.064). Intracranial and intra-abdominal injuries and skull fractures were equally frequent, but other extrathoracic fractures were more common with abuse (70.2% vs. 16.7%, P < 0.001). Abused infants and toddlers have fewer intrathoracic injuries but more rib fractures than accidentally injured peers. This likely reflects different injury mechanics.

    Hogeweg, Laurens E.; Mol, Christian; de Jong, Pim A.; van Ginneken, Bram

    2010-03-01

    The computer aided diagnosis (CAD) of abnormalities on chest radiographs is difficult due to the presence of overlapping normal anatomy. Suppression of the normal anatomy is expected to improve performance of a CAD system, but such a method has not yet been applied to the computer detection of interstitial abnormalities such as occur in tuberculosis (TB). The aim of this research is to evaluate the effect of rib suppression on a CAD system for TB. Profiles of pixel intensities sampled perpendicular to segmented ribs were used to create a local PCA-based shape model of the rib. The model was normalized to the local background intensity and corrected for gradients perpendicular to the rib. Subsequently rib suppressed images were created by subtracting the models for each rib from the original image. The effect of rib suppression was evaluated using a CAD system for TB detection. Small square image patches were sampled randomly from 15 normal and 35 TB-affected images containing textural abnormalities. Abnormalities were outlined by a radiologist and were given a subtlety rating from 1 to 5. Features based on moments of intensity distributions of Gaussian derivative filtered images were extracted. A supervised learning approach was used to discriminate between normal and diseased image patches. The use of rib suppressed images increased the overall performance of the system, as measured by the area under the receiver operator characteristic (ROC) curve, from 0.75 to 0.78. For the more subtly rated patches (rated 1-3) the performance increased from 0.62 to 0.70.

    2016-09-01

    Cervical myelopathy is the most common cause of acquired spinal cord compromise. The concept of degenerative cervical myelopathy (DCM), defined as symptomatic myelopathy associated with degenerative arthropathic changes in the spine axis, is being introduced. Given its progressive nature, treatment options have to be chosen in a timely manner. Surgical options include anterior discectomy and fusion (ACDF), anterior corpectomy and fusion (ACCF), arthroplasty (in highly select cases), posterior laminectomy with/without fusion, and laminoplasty. Indications for each should be carefully considered in individual patients. Riluzole, a sodium-glutamate antagonist, is a promising option to optimize neurologic outcomes post-surgery and is being examined in the CSM-Protect Randomized Controlled Trial. Preoperative risk assessment is mandatory for prognostication. Sagittal alignment is known to play an important role to optimize surgical outcome. Guidelines for optimal management of DCM are in process. In principle, all but the mildest cases of DCM should be offered surgery for optimal outcome. PMID:27250040

    At present, cervical cerclage is indicated in those patients with a classic history of cervical incompetence. For the majority of these patients, a postconceptional cerclage procedure is better suited because it is done after the fetus has been evaluated ultrasonographically for obvious abnormalities and after the risk for spontaneous abortion is past. The greatest experience is with the Shirodkar and the McDonald procedures; allowing for operator differences, neither appears to have an important advantage. The transabdominal cervicoisthmic cerclage may be a useful postconceptional procedure in the selected patient whose cervix is either markedly foreshortened, deeply lacerated, or infected. Preconceptional cerclages are best reserved for those rare patients in whom a markedly foreshortened incompetent cervix is associated with early second-trimester pregnancy losses (preconceptional isthmic cerclage) or in whom the cervix has a single, identifiable scar or deep laceration extending through the internal os (Lash procedure).

    The incidence of cervical cancer has hopefully been dropping down in our industrialized countries since the introduction of both primary and secondary prevention. Nevertheless, it is still lethal in one out of two affected women though the introduction of cytological screening has dramatically reduced the mortality. Progressive diffusion of anti-HPV vaccination, the broadening of the viral types concerned, its association with existing screening measures and finally the introduction of viral detection as a screening tool must optimize the results already obtained.

    Treatment-requiring diseases of the cervical spine in children are rare. The most common cases requiring medical assessment and treatment are acute torticollis and various accidents. A torticollis having lasted for more than a week should be recognized, because it can be treated by skull traction. Cervical spine fractures in children under school age are very rare, the most common being a fracture of the base of the dens of the second cervical vertebra. Cervical spine instability is almost always associated with an underlying disease. PMID:27400588

  2. Regional effects of ovariectomy and cadmium on bone mineral in ribs from aged female beagles

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate effects of estrogen depletion and cadmium (Cd) on bone calcium and to determine if these effects were localized in specific regions of ribs. Fourteen female beagles with 45Ca labeled skeletons were divided into four groups: sham controls (SO-); ovariectomized (OV-); shams exposed to Cd (SO+); ovariecomized exposed to Cd (OV+). Total Cd exposure period was 7 months, including 1 month by capsules and 6 months by drinking H2O. Ribs were taken at necropsy from 12 of the 14 dogs, and each rib was quartered. Wet, dry, and ash weights, as well as total Ca and 45Ca content, were determined for each quarter. Analysis of ribs from control animals demonstrated that a given rib is heterogeneous in composition. One end appears to be less mineralized and more metabolically active than other regions. The OV- and OV+ mid-rib regions had significantly lower dry and ash weights than SO-. Total Ca contents of these same regions were also decreased in the OV- and OV+. The only significant change in Ca/dry and Ca/ash was observed when comparing OV+ to SO-. Analysis of treatment suggests that there are regional effects following ovariectomy increased the loss of bone mineral occurring as a result of ovariectomy. 30 refs., 1 fig

    The development of technologies that make use of renewable energy is of great significance presently. A new kind of turbine called Split Reaction Water Turbine (SRWT) using PVC pipes as material is a major contribution towards harnessing the energy potentials of small stream low head water resources. SRWTs of diameter to height ratio (D/H = 110 cm/160 cm) were tested at the MSU-IIT College of Engineering Fluid Engineering Laboratory. Data on volumetric flow and pressure head at the turbine inlet of the SRWT were recorded using National Instrument Data Processing System using LabView software. In later experiments, guide ribs were installed at the vane of the exit nozzles in order to determine the difference in the performance of the ribbed and the non-ribbed SRWT. Simulations of the running SRWT were conducted using SOLIDWORKS software. Results of the simulations aided in the thorough analyses of the data from the experimental runs. A comparison of data from the ribbed and non-ribbed SRWT shows that guide ribs were effective in directing the momentum of the exiting water to improve the speed of rotation. In this study, the increase in the speed of the Split Reaction Water Turbine was as much as 46%.

    Intraspinal rib head dislocation is an important but under-recognized consequence of dystrophic scoliosis in patients with neurofibromatosis 1 (NF1). To present clinical and imaging findings of intraspinal rib head dislocation in NF1. We retrospectively reviewed clinical presentation, imaging, operative reports and post-operative courses in four NF1 patients with intraspinal rib head dislocation and dystrophic scoliosis. We also reviewed 17 cases from the English literature. In each of our four cases of intraspinal rib head dislocation, a single rib head was dislocated on the convex apex of the curve, most often in the mid- to lower thoracic region. Cord compression occurred in half of these patients. Analysis of the literature yielded similar findings. Only three cases in the literature demonstrates the MRI appearance of this entity; most employ CT. All of our cases include both MRI and CT; we review the subtle findings on MRI. Although intraspinal rib head dislocation is readily apparent on CT, sometimes MRI is the only cross-sectional imaging performed. It is essential that radiologists become familiar with this entity, as subtle findings have significant implications for surgical management. (orig.)

    This paper investigates using rib-bone atlases for automatic detection of rib-bones in chest X-rays (CXRs). We built a system that takes patient X-ray and model atlases as input and automatically computes the posterior rib borders with high accuracy and efficiency. In addition to conventional atlas, we propose two alternative atlases: (i) automatically computed rib bone models using Computed Tomography (CT) scans, and (ii) dual energy CXRs. We test the proposed approach with each model on 25 CXRs from the Japanese Society of Radiological Technology (JSRT) dataset and another 25 CXRs from the National Library of Medicine CXR dataset. We achieve an area under the ROC curve (AUC) of about 95% for Montgomery and 91% for JSRT datasets. Using the optimal operating point of the ROC curve, we achieve a segmentation accuracy of 88.91±1.8% for Montgomery and 85.48±3.3% for JSRT datasets. Our method produces comparable results with the state-of-the-art algorithms. The performance of our method is also excellent on challenging X-rays as it successfully addressed the rib-shape variance between patients and number of visible rib-bones due to patient respiration.

    1988-04-01

    A common occurrence in rat teratology studies, supernumerary ribs, have been considered to be indicative of teratogenicity by some authors but not to be so indicative by others. As a teratogenic event is, by definition a permanent change, a study to follow the fate of supernumerary ribs in the development of adulthood of the rat was undertaken. An established teratogen in the rat, aspirin, was used to increase the frequency of supernumerary ribs. Even though aspirin treatment of the dams doubled the initial frequency of supernumerary ribs the results show that over the first 60 days post-partum their frequency in both control and treated groups decline to essentially zero. This decline in frequency of supernumerary ribs is complemented by an increase in the proportion of foetuses with a fully developed transverse process on the first lumbar vertebra. The proposal that supernumerary ribs in the rat are a result of developmental delays in a labile region of the axial skeleton and not a manifestation of a teratogenic event is presented.

    Full Text Available Turkish people, who have a long historical background, have a rich culture in terms of cuisine. “Dolma” (meal made by stuffing/wrapping is one of the most important dishes of the Turkish Cuisine. Turks produced very different types of meals made by stuffing or wrapping and by combining herbals, meat and offals products. Stuffed Lamb Ribs (in Turkish; Kaburga Dolması or Sura is a special dish that is known in many regions of Turkey. Since it is a dish whose preparation is hard and requires virtuosity, it is generally cooked as a feast meal on religious holidays, and commonly cooked on the Feast of Sacrifice for Muslims. This study aims to present how “Stuffed Lamb Ribs” are prepared, which is one of the traditional dishes of Turkish Cuisine and is one stuffed dish that has started to become forgotten. In this study, the data was collected by personal interviews with source people who are over 60 years old, live in different provinces of Turkey, and traditionally cook this dish. This study ensures the promotion of a very special taste, which has begun to be forgotten and is not known widely even in Turkey, at an international level.

  10. Design of 9 tesla superconducting solenoid for VECC RIB facility

    International Nuclear Information System (INIS)

    An ISOL post-accelerator type of RIB facility is being developed at our centre. The post acceleration scheme of a Radio Frequency Quadrupole (RFQ) followed by five IH LINAC cavities will provide energy of about 1.05 MeV/u. For further accelerating up to 2 MeV/u Superconducting Quarter Wave Resonators (SCQWR) will be used. The radial defocusing of the beam bunch during the acceleration using SCQWRs will be taken care of by a Superconducting Solenoid (SCS) within the same cryostat. In this report the electromagnetic design of an SCS will be discussed. A 9 T SCS having effective length of 340 mm has been designed with the special requirement that the fringing field should fall sharply to a value less than 100 mT at the surfaces of the adjacent superconducting cavities. The designed solenoid comprise of two co-axial split solenoid conductors surrounded by iron shields and a pair of bucking coils. Optimizations have been carried out for the total current sharing of the main coils and the bucking coils as well as for the relative orientation and dimension of each component of the solenoid.

    2015-11-01

    Full Text Available Osteosynthesis surgery for rib fractures is controversial and challenging. This study developed a noval poly(ε-caprolactone (PCL-based biodegradable “cable-tie” fixator for osteosynthesis surgery for rib fractures. A biodegradable fixator specifically for fractured ribs was designed and fabricated by a micro-injection molding machine in our laboratory. The fixator has three belts that could be passed through matching holes individually. The locking mechanism allows the belt movement to move in only one direction. To examine the in vitro biomechanical performance, ribs 3–7 from four fresh New Zealand rabbits were employed. The load to failure and stress-strain curve was compared in the three-point bending test among native ribs, titanium plate-fixed ribs, and PCL fixator-fixed ribs. In the in vivo animal study, the sixth ribs of New Zealand rabbits were osteotomized and osteosynthesis surgery was performed using the PCL fixator. Outcomes were assessed by monthly X-ray examinations, a final micro-computed tomography (CT scan, and histological analysis. The experimental results suggested that the ribs fixed with the PCL fixator were significantly less stiff than those fixed with titanium plates (p < 0.05. All ribs fixed with the PCL fixators exhibited union. The bridging callus was confirmed by gross, radiographic micro-three-dimensional (3D CT, and histological examinations. In addition, there was no significant inflammatory response of the osteotomized ribs or the PCL-rib interface during application. The novel PCL fixator developed in this work achieves satisfactory results in osteosynthesis surgery for rib fractures, and may provide potential applications in other orthopedic surgeries.

The previous methods of classifying cervical spondylosis are Ihe summaries□f personal experiences without objective base. Therefore, il is significant to investigate syndrome classification using clusteranalysis and principal component analysis.OBJECTIVE: To investigate the distribution traits in cervical spondylosis according to different symptom types of traditionalChinese medicine using cluster analysis and principal analysis.METHODS: The questionnaire was designed according to the clinical manifestations in cervical spondylosis patients. Symptoms,clinical signs, tongue, pulsa and other diagnostic messages of 575 patients were collected, to analyze 98 common symptomsusing cluster analysis and principal component analysis.RESULTS AND CONCLUSION: According to the results of cluster analysis, the disease could be divided into eight categories:dampness-heat energizer, phlegm and wet resistance channels and collaterals, deficiency of qi and blood, deficiency ofliver-Kidney yin. Deficiency of (tie spleen and kidney-yang/. Blood stasis and qi stagnation, cold dampness resistance channelsand collaterals, deficiency of liver and spleen. We found that mosl of their disease mechanisms were "state of evil domination",which was caused by qi stagnation, dampness-heat, cold dampness, phlegm-dampness, blood stasis. Meanwhile, because of theexistence of asthenia of healthy 171, the main representation was deficiency of yin, deficiency of yang, deficiency of qi anddeficiency of blood. Cluster analysis and principle component analysis are scientific to some extent used in the research oftraditional Chinese medical syndrome types.%背景:目前对于颈椎病的中医分型相对单一,缺乏各型颈椎病一一分型辨治的中医特色与特点.以往各型颈椎病分型主要是以个人经验

  14. Pulmonary nodule registration in serial CT scans based on rib anatomy and nodule template matching

    International Nuclear Information System (INIS)

    An automated method is being developed in order to identify corresponding nodules in serial thoracic CT scans for interval change analysis. The method uses the rib centerlines as the reference for initial nodule registration. A spatially adaptive rib segmentation method first locates the regions where the ribs join the spine, which define the starting locations for rib tracking. Each rib is tracked and locally segmented by expectation-maximization. The ribs are automatically labeled, and the centerlines are estimated using skeletonization. For a given nodule in the source scan, the closest three ribs are identified. A three-dimensional (3D) rigid affine transformation guided by simplex optimization aligns the centerlines of each of the three rib pairs in the source and target CT volumes. Automatically defined control points along the centerlines of the three ribs in the source scan and the registered ribs in the target scan are used to guide an initial registration using a second 3D rigid affine transformation. A search volume of interest (VOI) is then located in the target scan. Nodule candidate locations within the search VOI are identified as regions with high Hessian responses. The initial registration is refined by searching for the maximum cross-correlation between the nodule template from the source scan and the candidate locations. The method was evaluated on 48 CT scans from 20 patients. Experienced radiologists identified 101 pairs of corresponding nodules. Three metrics were used for performance evaluation. The first metric was the Euclidean distance between the nodule centers identified by the radiologist and the computer registration, the second metric was a volume overlap measure between the nodule VOIs identified by the radiologist and the computer registration, and the third metric was the hit rate, which measures the fraction of nodules whose centroid computed by the computer registration in the target scan falls within the VOI identified by the

    Application of artificial roughness on underside of absorber surface has been found to be effective technique to improve thermo hydraulic performance of solar air heaters. In progression to the previous researches, the present study discloses the effect of broken V-rib roughness combined with staggered ribs on heat transfer and friction in a flow through artificially roughened solar air heater duct. The experimentations were performed to collect the data on heat transfer and friction by varying the Reynolds number (Re) between 3000 and 17,000, relative gap position (s'/s) from 0.2 to 0.8, for the fixed values of relative staggered rib pitch p'/p = 0.6, relative staggered rib size r/e = 1, relative roughness pitch p/e = 10, relative roughness height e/D{sub h} = 0.043, relative gap size g/e = 1, and angle of attack {alpha} = 60 . The present roughness geometry with relative gap position (s'/s) of 0.6 corresponding to flow Reynolds number (Re) of 13,150 yields the best thermohydraulic performance. (orig.)

    FMN riboswitches are genetic elements that, in many bacteria, control genes responsible for biosynthesis and/or transport of riboflavin (vitamin B2 ). We report that the Escherichia coli ribB FMN riboswitch controls expression of the essential gene ribB coding for the riboflavin biosynthetic enzyme 3,4-dihydroxy-2-butanone-4-phosphate synthase (RibB; EC 4.1.99.12). Our data show that the E. coli ribB FMN riboswitch is unusual because it operates at the transcriptional and also at the translational level. Expression of ribB is negatively affected by FMN and by the FMN analog roseoflavin mononucleotide, which is synthesized enzymatically from roseoflavin and ATP. Consequently, in addition to flavoenzymes, the E. coli ribB FMN riboswitch constitutes a target for the antibiotic roseoflavin produced by Streptomyces davawensis.

    In 1976, Dr. Zhao Dinglin and Dr. Zhang Wenming made the breakthrough. Based on the purpose of releasing bone induced pressure they had completed the first anterior radical cervical decompression and bone grafting + partial rotation. Since then, chinese scholars had continuously explored the pathogenesis, pathological anatomy, pathophysiological features, reasonable classiifcation and many other related issues of cervical spondylosis. In several years from 1970s, the author proposed the concept of cervical nonfusion technology, to accomplish various designs and producing, which was subsequently used in clinical treatment. We brought forward Luschka’s joint diseases and anterior-lateral decompression surgery on the purpose of resecting Luschka’s joints. To reduce the damage to the cervical spine anatomy, we had designed a cervical anterior undermining decompression instrument ( including “L” shape, “T” shape, “Y” shape and single vertebrae ). We cooperated with Shanghai No. Six Surgical Instruments Factory and produced both conventional and special instruments on cervical spine surgery to improve the accuracy and security in operations. After that, we designed cervical hollow threaded ifxator, artiifcial cervical vertebra body and artiifcial vertebra plate. Combined with the research results concluded by three national forums, we elaborated basic concepts and definitions of cervical researches at different periods. On this basis we introduced those crucial issues such as the natural outcome of the cervical spondylosis, pathological anatomy features, pathogenesis and so on. Also, for some related trending topics we expressed personal viewpoints. For instance, selection of operative approach ( anterior or posterior ), origin, choice and effectiveness of nonfusion technique, and operative essentials of less invasion. Furthermore we put forward the main points on more common clinical diseases: Luschka’s joint diseases and anterior central spinal artery

    Proton beam therapy (PBT) is the preferred modality for early-stage lung cancer. Compared with X-ray therapy, PBT offers good dose concentration as revealed by the characteristics of the Bragg peak. Rib fractures (RFs) after PBT lead to decreased quality of life for patients. However, the incidence of and the risk factors for RFs after PBT have not yet been clarified. We therefore explored the relationship between irradiated rib volume and RFs after PBT for early-stage lung cancer. The purpose of this study was to investigate the incidence and the risk factors for RFs following PBT for early-stage lung cancer. We investigated 52 early-stage lung cancer patients and analyzed a total of 215 irradiated ribs after PBT. Grade 2 RFs occurred in 12 patients (20 ribs); these RFs were symptomatic without displacement. No patient experienced more severe RFs. The median time to grade 2 RFs development was 17 months (range: 9-29 months). The three-year incidence of grade 2 RFs was 30.2%. According to the analysis comparing radiation dose and rib volume using receiver operating characteristic curves, we demonstrated that the volume of ribs receiving more than 120 Gy3 (relative biological effectiveness (RBE)) was more than 3.7 cm(3) at an area under the curve of 0.81, which increased the incidence of RFs after PBT (P < 0.001). In this study, RFs were frequently observed following PBT for early-stage lung cancer. We demonstrated that the volume of ribs receiving more than 120 Gy3 (RBE) was the most significant parameter for predicting RFs. PMID:27087118

    More than a century ago, the first scientific report was published about fracture fixation with plates. During the 1950's, open reduction and plate fixation for fractures were standardized by the founders of Arbeitsgemeinschaft für osteosynthesefragen/Association for the Study of Internal Fixation. Since the introduction of plate fixation for fractures, several plates and screws have been developed, all with their own characteristics. To accomplice more fracture stability, it was thought the bigger the plate, the better. The counter side was a compromised blood supply of the bone, often resulting in bone necrosis and ultimately delayed or non-union. With the search and development of new materials and techniques for fracture fixation, less invasive procedures have become increasingly popular. This resulted in the minimally invasive plate osteosynthesis (MIPO) technique for fracture fixation. With the MIPO technique, procedures could be performed with smaller incisions and thus with less soft tissue damage and a better preserved blood supply. The last 5 years rib fixation has become increasingly popular, rising evidence has become available suggesting that surgical rib fixation improves outcome of patients with a flail chest or isolated rib fractures. Many surgical approaches for rib fixation have been described in the old literature, however, most of these techniques are obscure nowadays. Currently mostly large incisions with considerable surgical insult are used to stabilize rib fractures. We think that MIPO deserves a place in the surgical treatment of rib fractures. We present the aspects of diagnosis, preoperative planning and operative techniques in regard to MIPO rib fixation.

    The effect of vortex generators on the mass (heat) transfer from the ribbed passage of a two pass turbine blade coolant channel is investigated with the intent of optimizing the vortex generator geometry so that significant enhancements in mass/heat transfer can be achieved. In the experimental configuration considered, ribs are mounted on two opposite walls; all four walls along each pass are active and have mass transfer from their surfaces but the ribs are non-participating. Mass transfer measurements, in the form of Sherwood number ratios, are made along the centerline and in selected inter-rib modules. Results are presented for Reynolds number in the range of 5,000 to 40,000, pitch to rib height ratios of 10.5 and 21, and vortex generator-rib spacing to rib height ratios of 0.55, and 1.5. Centerline and spanwise averaged Sherwood number ratios are presented along with contours of the Sherwood number ratios. Results indicate that the vortex generators induce substantial increases in the local mass transfer rates, particularly along the side walls, and modest increases in the average mass transfer rates. The vortex generators have the effect of making the inter-rib profiles along the ribbed walls more uniform. Along the side walls, horse-shoe vortices that characterize the vortex generator wake are associated with significant mass transfer enhancements. The wake effects and the levels of enhancement decrease somewhat with increasing Reynolds number and decreasing pitch.

    Effects of aspect ratio on heat/mass transfer were investigated in rectangular channels with two different V-shaped rib configurations, which are continuous V-shaped rib configuration with a 60 attack angle, and multiple (staggered) V-shaped rib configuration with a 45 attack angle. The square ribs were attached on the test section in a parallel manner. A naphthalene sublimation method was used to measure the local heat/mass transfer coefficients. For the continuous V-shaped rib configuration, two pairs of counter-rotating vortices were generated in the channel, and high transfer region was formed at the center of the ribbed walls. However, for the multiple V-shaped rib configuration with 45 attack angle, asymmetric secondary flow patterns were generated due to its geometric features, resulting in uniform heat/mass transfer distributions. The effect of channel aspect ratio was more significant for the continuous 60 V-shaped rib than for the multiple 45 V-shaped rib configuration. (author)

    Curative-intent radical radiotherapy of cervical cancer consists of external-beam radiotherapy, brachytherapy, and concomitant chemotherapy with cisplatin. For each element, new developments aim to improve tumor control rates or treatment tolerance. Intensity-modulated radiotherapy (IMRT) has been shown to reduce gastrointestinal toxicity and can be used to selectively increase the radiotherapy dose. Individualized, image-guided brachytherapy enables better adaptation of high-dose volumes to the tumor extension. Intensification of concomitant or sequential systemic therapy is under evaluation.

    Cervical radiculopathy is a common diagnosis with a peak onset in the fifth decade. The most commonly affected nerve root is C7, C6, and C8. The etiology is often compressive, but may arise from noncompressive sources. Patients commonly complain of pain, weakness, numbness, and/or tingling. Examination may reveal sensory or motor disturbance in a dermatomal/myotomal distribution. Neural compression and tension signs may be positive. Diagnostic tests include imaging and electrodiagnostic study. Electrodiagnostic study serves as an extension of the neurologic examination. Electrodiagnostic findings can be useful for patients with atypical symptoms, potential pain-mediated weakness, and nonfocal imaging findings.

    , finally generating the syrinx. On the other hand in cervical spondylosis the stenotic elements can affect subarachnoid space. These elements rubbing towards spinal cord during movements of the neck can generate arachnoiditis, subarachnoid hemorrhages and arachnoid adhesions. Analyzing the literature these "complications" of cervical spondylosis are described at the origin of syringomyelia. So surgical decompression, enlarging medullary canal prevents rubbings and contacts between the bone-ligament structures of the spine towards spinal cord and subarachnoid space therefore syringomyelia. Perhaps stabilization is also necessary to prevent instability of the cervical spine at the base of central cord syndrome or syringomyelia. Finally although patients affected by central cord syndrome are usually managed conservatively we advocate, also for them, surgical treatment in cases affected by advanced state of the symptoms and MRI.

    Several studies investigating myofascial pain syndrome include assessments of range of motion (ROM) as a diagnostic criterion. However, the value of ROM in this context has not yet been evaluated in controlled clinical studies. We aimed to examine whether patients with myofascial pain syndrome display alterations of ROM when compared to healthy subjects. Twenty-two individuals (13 females, 9 males; aged 33.4 ± 13.9 yrs) afflicted with active myofascial trigger points in the upper trapezius muscle as well as 22 age and sex matched healthy controls were included. All subjects underwent an examination of maximal active cervical ROM in flexion/extension assessed by means of a 3D ultrasonic movement analysis system (30 Hz; Zebris CMS 70). In the patients group, pressure pain threshold (PPT) of the trigger points was determined using a pressure algometer. Maximum range of motion in the sagittal plane did not differ between individuals with MTrP (125.9 ± 23.2°, 95% CI: 116.2-135.6°) and asymptomatic subjects (128.2 ± 20.4°, 95% CI: 119.7-136.7°; p > .05). In patients, PPT (1.7 ± .6, 95% CI: 1.5-1.9) was not correlated with cervical mobility (r = -.13; p > .05). Based on these pilot data, range of motion in flexion/extension is not a valid criterion for the detection of myofascial trigger points. Additional research incorporating movement amplitudes in other anatomical planes and additional afflicted muscles should be conducted in order to further delineate the relative impact of MTrP on range of motion.

    Full Text Available Introduction: Trauma is one of the most important causes of death in patients under 40 years of age and the third common cause of death regardless of age. Rib cage damages are one of the major reasons for death in the early minutes post-trauma. Therefore, the present study aimed to evaluate the frequency of intra-abdominal injury in the patients with rib fracture who were referred to emergency department. Methods: This cross-sectional study included 60 patients with rib fractures who were admitted to the emergency department of Poorsina Hospital, Rasht, Iran, from March 2011 to March2012. A checklist was filled out for all the patients including age, sex, trauma mechanism, side and site of fracture, the number of broken ribs, the results of abdominal ultrasonography, the need for laparotomy and mortality. The collected data were classified based on descriptive statistics and analyzed using SPSS 16. Results: 60 patients with the mean age of 47.26±13.71 years were admitted to the emergency department during this time (81.7% male. The most common mechanism of trauma was car accident [22(36.7%]. Among these 60 patients, 71 rib fractures in 3 levels of chest (upper, middle, lower were detected and 50 (83.3% in the same area. Mean number of fractured ribs was 2.85±2.2 (minimum: 1, maximum 10. In 3 (5% patients, fracture was on both sides. The results of abdominal ultrasonography in 7 (11.7% patients were positive. The number of fractured ribs (p=0.017 and the area of the fracture (p=0.048 showed a significant correlation with the presence of intra-abdominal free fluid. The fracture of more than 2 ribs directly correlated with the possibility of intra-abdominal hemorrhage (p<0.0001. Conclusion: Based on the results of this study, it seems that the number and area of the fractured ribs directly and significantly correlate with the probability of abdominal trauma based on the results of abdominal ultrasonography.

    Purpose: This paper describes the design and experimental evaluation of the Methods and Advanced Equipment for Simulation and Treatment in Radiation Oncology (MAESTRO) thorax phantom, a new anthropomorphic moving ribcage combined with a 3D tumor positioning system to move target inserts within static lungs. Methods: The new rib cage design is described and its motion is evaluated using Vicon Nexus, a commercial 3D motion tracking system. CT studies at inhale and exhale position are used to study the effect of rib motion and tissue equivalence. Results: The 3D target positioning system and the rib cage have millimetre accuracy. Each axis of motion can reproduce given trajectories from files or individually programmed sinusoidal motion in terms of amplitude, period, and phase shift. The maximum rib motion ranges from 7 to 20 mm SI and from 0.3 to 3.7 mm AP with LR motion less than 1 mm. The repeatability between cycles is within 0.16 mm root mean square error. The agreement between CT electron and mass density for skin, ribcage, spine hard and inner bone as well as cartilage is within 3%. Conclusions: The MAESTRO phantom is a useful research tool that produces programmable 3D rib motions which can be synchronized with 3D internal target motion. The easily accessible static lungs enable the use of a wide range of inserts or can be filled with lung tissue equivalent and deformed using the target motion system.

    Full Text Available A comprehensive mathematical model of the performance of the cathode-supported solid oxide fuel cell (SOFC with syngas fuel is presented. The model couples the intricate interdependency between the ionic conduction, electronic conduction, gas transport, the electrochemical reaction processes in the functional layers and on the electrode/electrolyte interfaces, methane steam reforming (MSR and the water gas shift reaction (WGSR. The validity of the mathematical model is demonstrated by the excellent agreement between the numerical and experimental I-V curves. The effect of anode rib width and cathode rib width on gas diffusion and cell performance is examined. The results show conclusively that the cell performance is strongly influenced by the rib width. Furthermore, the anode optimal rib width is smaller than that for cathode, which is contrary to anode-supported SOFC. Finally, the formulae for the anode and cathode optimal rib width are given, which provide an easy to use guidance for the broad SOFC engineering community.

    Full Text Available Background  A cartilage wedge block and covering flap are standard procedures for firmelevation of the ear in microtia correction. However, using costal cartilage for elevation ofthe reconstructed auricle can be insufficient, and the fixed cartilage wedge block may beabsorbed or may slip out. Furthermore, elevating covering flaps is time-consuming and usesup fascia, a potential source of reconstruction material. Therefore, we propose an innovativemethod using autologous onlay rib bone graftfor auricular elevation ofmicrotia.Methods  From February 1995 to August 2012, 77 patients received a first stage operationwith a rib cartilage framework graft. In the second stage operation, a small full thickness ofrib bone was harvested through the previous donor scar. The bihalved rib bone was insertedinto the subperiosteal pocket beneath the cartilage framework.Results  The follow-up time ranged from 1 month to 17 years, with a mean of 3 years. Allof the patients sustained the elevation of their ears very well during the follow-up period.Donorsite problems, exceptfor hypertrophic scars,were not observed. Surgery-related complications,specifically skin necrosis, infection, or hematoma, occurred in 4 cases.Conclusions  Onlay rib bone graft used to elevate the reconstructed auricle is a more anatomically appropriate materialthan cartilage, due to the bone-to-bone contact between thebone graft and the temporal bone. Postoperative minor correction of the elevation degree isstraightforward and the skin graft survives better. Therefore, reconstructed auricle elevationusing onlay rib bone graftis a useful and valuablemethod.

    Metallic structures made of ribbed iron bars (ADN-420) are of common use in sheds and supporting structures. Usually, trusses are constructed with many pieces of ribbed iron bars, combined together through a welding process. Although ribbed iron manufacturers do not recommend this type of structure it is still frequently used. The main weakness of these trusses is the welding point because ribbed iron is not a material suitable for welding. This work presents results obtained from an analysis of welding points between ribbed iron bars extracted from a collapsed truss, by means of conventional (optical) and digital holographic interferometry (HI and DHI, respectively). The experiments were divided in two different series of studies. The first series were performed by HI on metallographic samples while the second series were done by DHI on different welding points. These results were complemented by metallographic analysis made in an external laboratory. DHI indicated that the bars did not have important failures but evidenced defects in one of the welding points under analysis. This information together with metallographic results allowed inferring that the collapse was probably due to an error in the design of the structure, since the iron bars were out of standard compliance.

  15. Stress fractures of the ribs in elite competitive rowers: a report of nine cases

    International Nuclear Information System (INIS)

    The objective was to report the clinical and imaging patterns of nine cases of stress fractures of the rib diagnosed in Italian Olympic rowers. Nine patients with stress fractures of the rib detected from 103 (8.7%) Italian team rowers competing between May 2000 and May 2006 were identified based on the database of a sports medicine institute. All athletes were male. They were aged between 17 and 31 years (mean: 24.4). Patient weight, fracture location, rowing side and imaging methods employed were noted. The diagnosis was made based on history, clinical examination and Tc-99m MDP bone scintigraphy. Eight of the 9 fractures were located anterolaterally between the fourth and ninth rib. In 1 of the 5 athletes with standard radiographs, a fracture line was visible and in 4 there was callus formation. In 2 athletes sonography was performed, which detected discontinuity of the rib surface and callus formation (1 case each). Stress fractures of the ribs are relatively common in competitive rowers. They are characterized by increasing lateral chest pain and typical scintigraphic, radiographic and sonographic findings. (orig.)

    Background: Radiofrequency (RF) ablation of lung tumors has become a treatment of choice, especially for unresectable cases. However, RF ablation of small lung lesions located just beneath the rib is difficult. Purpose: To evaluate the efficacy and safety of gantry tilting for the performance of RF ablation of peripheral lesions located beneath the rib. Material and Methods: Our study was based on 18 of 293 lesions in the lung for which RF ablation was performed under CT scan fluoroscopic guidance at our institution between October 2004 and March 2009. For these 18 lesions, RF ablation was performed with gantry tilting because a rib blocked visualization of the RF ablation route even after other attempts had been made to change the relationship between the target and the rib. Results: All RF needles, with only one exception, were successfully advanced to hit the tumor. The commonest complication was a pneumothorax, which occurred in seven procedures. No serious complications occurred. The progression-free rates were 82.4% at 6 months, 62.5% at 12 months, and 30% at 24 months. Mean local progression-free duration was 17.6+-11.6 months (range 4-36 months). Conclusion: RF ablation under CT scan fluoroscopic guidance with gantry tilt is a useful and safe technique for RF ablation of lung nodules located beneath the rib

    First-rib stress fractures have been described in adolescent athletes in various sports, with only one prior case report of first-rib stress fractures in an adolescent female swimmer. There is a need for research on the cause, management, and prevention of these injuries as they lead to significant morbidity and critical time away from sport for these aspiring athletes. We aimed to describe first-rib stress fractures as a potential cause for non-specific atraumatic chronic shoulder pain in adolescent swimmers and to discuss the different presentations, unique risk factors, treatment, and potential injury prevention strategies of such fractures. We discussed two such cases which were successfully treated with activity modification with restriction of all overhead activity, gradually progressive physical therapy and a return to swimming protocol. First-rib stress fractures can vary in presentation and should be in the differential diagnosis in adolescent swimmers with chronic shoulder pain. These injuries can be successfully managed with rest from overhead activities and physical therapy. Gradual return to competitive swimming can be achieved even with non-union of a first-rib stress fracture. Emphasis on balanced strength training in different muscle groups and proper swimming technique is essential to prevent these injuries. PMID:26539736

    Full Text Available OBJETIVO: o objetivo deste trabalho foi identificar a ocorrência da síndrome do disco adjacente secundária à fusão intervertebral, no segmento cervical, e os fatores prognósticos associados. MÉTODOS: foram analisados os prontuários e exames de imagem de 209 indivíduos submetidos ao tratamento cirúrgico da doença degenerativa cervical, sendo 169 casos por via anterior e em 40 por via posterior, no HC-FMUSP, no período de março de 1993 a janeiro de 2007. A avaliação clínica foi quantificada pela escala da Japanese Orthopaedic Association (JOA, com média de segmento de 80 meses. A análise radiológica foi baseada nos critérios de instabilidade de White e Panjabi em todos os casos. A degeneração discal foi mensurada segundo a escala de Kellgren antes e após a cirurgia. RESULTADOS: no total, diagnosticou-se a síndrome do disco adjacente em 30 casos (17,75%, com média de intervalo de tempo de incidência de 28,5 meses após a fusão ou 2,9 casos/ano. Houve um aumento das alterações degenerativas nos exames radiológicos em níveis adjacentes à fusão por via anterior em 41,42% e em 52,5% por via posterior sem fusão, avaliados pela escala de Kellgren, com taxa de degeneração de 6,7% ao ano, sem correlação com alterações clínicas. CONCLUSÕES: alterações no alinhamento fisiológico sagital da coluna e a sua gravidade predispõem ao desenvolvimento da síndrome. Não foi observada incidência da síndrome em casos de pseudoartrose ou utilização de metacrilato, portanto onde não ocorreu a fusão. A utilização de descompressão e fusão, por via anterior, está associada à possibilidade de desenvolvimento de um novo quadro de mielorradiculopatia no período pós-operatório. Fusão em um nível que envolva a quinta ou sexta vértebras cervicais, fixação com placas e pré-existência da evidência radiográfica de degeneração de disco adjacente mostraram-se como os grandes fatores de risco para o seu surgimento

    Keegan (1965) reported a patient who presented with "dissociated motor loss," an acute paralysis of the upper extremity with minimal sensory signs and no long tract signs, and documented an anterior root lesion following autopsy. Sobue et al. (1975) reported similar cases using the term "cervical spondylotic amyotrophy (CSA)," but postulated pathology of the anterior horn. Although Keegan's "dissociated motor loss" surely referred to isolated motor paresis with no or minimal sensory signs, contrary to existing criticism, a more general term, CSA, should be preferred. CSA is divided into proximal and distal types. Distal CSA often presents with a drop finger, and thus may be misdiagnosed as posterior interosseous nerve palsy. Documentation of the involvement of ulnar muscles by clinical signs and EMG would lead to the diagnosis of distal CSA. Proximal CSA may be confused with neuralgic amyotrophy (NA), although the sparing of the serratus anterior and the stereotypic involvement of deltoid, infraspinatus, biceps brachii, and brachioradialis suggest CSA. Cervical MRI is not diagnostic in around half of CSA cases, and denervation in paraspinal EMG is a more sensitive test that can exclude NA. Amyotrophic lateral sclerosis is another important differential diagnosis for CSA. PMID:27156504

    Full Text Available Abstract Background Patients with cervical radicular syndrome due to disc herniation refractory to conservative treatment are offered surgical treatment. Anterior cervical discectomy is the standard procedure, often in combination with interbody fusion. Accelerated adjacent disc degeneration is a known entity on the long term. Recently, cervical disc prostheses are developed to maintain motion and possibly reduce the incidence of adjacent disc degeneration. A comparative cost-effectiveness study focused on adjacent segment degeneration and functional outcome has not been performed yet. We present the design of the NECK trial, a randomised study on cost-effectiveness of anterior cervical discectomy with or without interbody fusion and arthroplasty in patients with cervical disc herniation. Methods/Design Patients (age 18-65 years presenting with radicular signs due to single level cervical disc herniation lasting more than 8 weeks are included. Patients will be randomised into 3 groups: anterior discectomy only, anterior discectomy with interbody fusion, and anterior discectomy with disc prosthesis. The primary outcome measure is symptomatic adjacent disc degeneration at 2 and 5 years after surgery. Other outcome parameters will be the Neck Disability Index, perceived recovery, arm and neck pain, complications, re-operations, quality of life, job satisfaction, anxiety and depression assessment, medical consumption, absenteeism, and costs. The study is a randomised prospective multicenter trial, in which 3 surgical techniques are compared in a parallel group design. Patients and research nurses will be kept blinded of the allocated treatment for 2 years. The follow-up period is 5 years. Discussion Currently, anterior cervical discectomy with fusion is the golden standard in the surgical treatment of cervical disc herniation. Whether additional interbody fusion or disc prothesis is necessary and cost-effective will be determined by this trial

    Objective: The role of human papillomavirus (HPV) in the development of cervical carcinoma has been clearly established but other factors could be involved in cervical tumorigenesis such as loss of heterozygosity (LOH) and microsatellite instability (MI). The aim of the present study was to investigate the genetic instability in cervical carcinoma tissues and provide evidence for discoveringnew tumor suppressor genes and screening diagnostic molecular marker of cervical carcinoma. Methods: Fifty primary cervical carcinoma samples from high-incidence area were analyzed by PCR for HPV16 infection, LOH and microsatellite instability. Results: HPV16 was detected in 88% of the cases. Sixty-six percent of total cases showed LOH with no more than 3 different loci per case. The highest frequency of the allelic loss was found in D18S474 (18q21, 40.5%). MI was detected in 4 cases (8%) only. Conclusion: Different percentages of LOH on specific chromosomal regions were found and MI was very infrequent in cervical carcinoma. The putative suppressor gene(s) could be located on specific chromosome regions such as 18q, and genetic instability could be involved in cervical tumorigenesis.

    It is expensive and laborious to evaluate carcass composition in beef cattle. The objective of this study was to evaluate a method to predict the 9th to 11th rib section (rib) composition through empirical equations using dual energy X-ray absorptiometry (DXA). Dual energy X-ray absorptiometry is a validated method used to describe tissue composition in humans and other animals, but few studies have evaluated this technique in beef cattle, and especially in the Zebu genotype. A total of 116 rib were used to evaluate published prediction equations for rib composition and to develop new regression models using a cross-validation procedure. For the proposed models, 93 ribs were randomly selected to calculate the new regression equations, and 23 different ribs were randomly selected to validate the regressions. The rib from left carcasses were taken from Nellore and Nellore × Angus bulls from 3 different studies and scanned using DXA equipment (GE Healthcare, Madison, WI) in the Health Division at Universidade Federal de Viçosa (Viçosa, Brazil). The outputs of the DXA report were DXA lean (g), DXA fat free mass (g), DXA fat mass (g), and DXA bone mineral content (BMC; g). After being scanned, the rib were dissected, ground, and chemically analyzed for total ether extract (EE), CP, water, and ash content. The predictions of rib fat and protein from previous published equations were different ( 0.05), respectively, then the equation correctly estimated the rib composition. Comparing observed and predicted values using the new equations, Mayer's test was not significant for lean mass ( = 0.26), fat free mass ( = 0.67), EE mass ( = 0.054), and ash mass ( = 0.14). We concluded that the rib composition of Nellore and Nellore × Angus bulls can be estimated from DXA using the proposed equations. PMID:27285924

    Based on the process experiments, micrography analysis was dedicated to advancing the understanding of plastic flow of the metal in backward ball spinning of thin-walled tubular part with longitudinal inner ribs. Micrography analysis reveals that severe plastic deformation leads to grain refinement, grain orientation and grain flow line of the spun part. Based on rigid-plastic finite element method, DEFORME3D finite element code was used to simulate and analyze multi-pass backward ball spinning of thin-walled tubular part with longitudinal inner ribs. Finite element simulation results involve the distributions of the strain, the shape variation of the inner ribs as well as the prediction of the spinning loading.

    This article presents experimental investigations of composite sandwich plywood plates with cell type core and their connections between skin layers of birch plywood and a core of straight and curved plywood honeycomb-type ribs. This shape of core ribs provides several improvements for these plates in the manufacturing process as well as improves the mechanical properties of plywood plates. This specific form of ribs allows simplifying the manufacturing of these plates although it should be detailed and improved. The most typical cases (series of specimens) were compared to the results obtained from FEM (ANSYS) simulations. All thicknesses of elements are chosen according to plywood supplier assortment. Standard birch plywood (Riga Ply) plates were used - three layer plywood was chosen for skin elements (Surfaces) and three or five layer plywood was chosen for edge elements. Different bond pressures were taken to compare their influence on joint strength and stiffness.

  11. The battered child syndrome

    International Nuclear Information System (INIS)

    The recognition of a battered child represents a challenge for all groups of adults dealing with children. Radiology plays a special role in this setting. By detection typical injuries, imaging is able to confirm the suspicion of a battered child. Recognition of those injuries on films, taken for other reasons, gives the caretaker an important hint, thus maybe preventing a fatal outcome for the child. One of the most important injury types is represented by the so called ''shakin baby syndrome''. The infant is held by the thorax and shaken. Thus causing a repetitive acceleration-deceleration trauma, which leads to the typical paravertebral rib fractures, intracranial bleeding and eye injuries. After shaking the child is thrown away, with subsequent injuries. The aim of this article is the presentation of an overview regarding the radiology of the battered child. Typical examples will be shown. (orig.)

    Full Text Available Maffucci syndrome is a rare, nonhereditary disorder manifesting early in life. The syndrome is characterized by presence of multiple hemangiomas and enchondromas mostly affecting the extremities. Haemangiomas are usually cutaneous, but may sometimes be visceral as well. Enchondromas commonly affect the long bones of the extremities. However, other areas including skull, ribs, vertebrae, larynx and trachea may also be involved. The presence of these lesions in the trachea and/or oropharynx may compromise the airway and cause difficulty during tracheal intubation. Complete airway examination and investigation is important to rule out any such lesion in a patient of Maffucci syndrome before planning for general anaesthesia with tracheal intubation.

  13. Blunt liver injury with intact ribs under impacts on the abdomen: a biomechanical investigation.

    Directory of Open Access Journals (Sweden)

    Yu Shao

    Full Text Available Abdominal trauma accounts for nearly 20% of all severe traffic injuries and can often result from intentional physical violence, from which blunt liver injury is regarded as the most common result and is associated with a high mortality rate. Liver injury may be caused by a direct impact with a certain velocity and energy on the abdomen, which may result in a lacerated liver by penetration of fractured ribs. However, liver ruptures without rib cage fractures were found in autopsies in a series of cases. All the victims sustained punches on the abdomen by fist. Many studies have been dedicated to determining the mechanism underlying hepatic injury following abdominal trauma, but most have been empirical. The actual process and biomechanism of liver injury induced by blunt impact on the abdomen, especially with intact ribs remained, are still inexhaustive. In order to investigate this, finite element methods and numerical simulation technology were used. A finite element human torso model was developed from high resolution CT data. The model consists of geometrically-detailed liver and rib cage models and simplified models of soft tissues, thoracic and abdominal organs. Then, the torso model was used in simulations in which the right hypochondrium was punched by a fist from the frontal, lateral, and rear directions, and in each direction with several impact velocities. Overall, the results showed that liver rupture was primarily caused by a direct strike of the ribs induced by blunt impact to the abdomen. Among three impact directions, a lateral impact was most likely to cause liver injury with a minimum punch speed of 5 m/s (the momentum was about 2.447 kg.m/s. Liver injuries could occur in isolation and were not accompanied by rib fractures due to different material characteristics and injury tolerance.

    This study investigated the structural, biomechanical and fractographic features of rib fractures in a piglet model, to test the hypothesis that fist impact, apart from thoracic squeezing, may result in lateral costal fractures as observed in abused infants. A mechanical fist with an accelerometer was constructed and fixed to a custom jig. Twenty stillborn piglets in the supine position were impacted on the thoracic cage. The resultant force versus time curves from the accelerometer data showed a number of steps indicative of rib fracture. The correlation between impact force and number of fractures was statistically significant (Pearson׳s r=0.528). Of the fractures visualized, 15 completely pierced the parietal pleura of the thoracic wall, and 5 had butterfly fracture patterning. Scanning electron microscopy showed complete bone fractures, at the zone of impact, were normal to the axis of the ribs. Incomplete vertical fractures, with bifurcation, occurred on the periphery of the contact zone. This work suggests the mechanism of rib failure during a fist impact is typical of the transverse fracture pattern in the anterolateral region associated with cases of non-accidental rib injury. The impact events investigated have a velocity of ~2-3m/s, approximately 2×10(4) times faster than previous quasi-static axial and bending tests. While squeezing the infantile may induce buckle fractures in the anterior as well as posterior region of the highly flexible bones, a fist punch impact event may result in anterolateral transverse fractures. Hence, these findings suggest that the presence of anterolateral rib fractures may result from impact rather than manual compression. PMID:27310573

  15. Correlation of Near-Wall Turbulence Structures with Heat Transfer in Ribbed-Pipe Flow

    2015-11-01

    Ribbed-pipe flow is one of the most commonly used flow configurations to enhance heat transfer, albeit, at the expense of increased pressure drop. The ribs mounted on the pipe wall differently alter the flow depending on the pitch, the distance between two neighboring ribs. When the pitch is short, fluid is trapped inside grooves, resulting in a low heat-transfer rate. When the pitch is long enough, however, the ribs disturb the flow by shedding vortices, resulting in heat-transfer enhancement. We aim at elucidating the correlation of near-wall turbulence induced by the shed vortices with the increased heat-transfer rate on the ribbed-pipe wall. Our analysis is based on our LES data base obtained for Re =24,000, Pr =0.71, PR(pitch ratio) =2, 4, 6, 8, 10, 18, BR(blockage ratio) =0.0625. Here, the bulk velocity and the pipe diameter are used as the velocity and length scales, respectively. Our presentation focuses on the near-wall distributions of the higher-order turbulence statistics including but not limited to rms of temperature fluctuation, cross-correlations, rms of vorticity, and turbulent heat fluxes. Octants and JPDF are also presented in order to clarify the prevailing heat-transfer mechanism in the immediate vicinity of the ribbed-pipe wall.

    @@ Cervical spondylopathy, also known as cervical syndrome, is a commonly encountered disease in the middle-aged and elderly people. This disease mostly results from the retrograde affection of the cervical intervertebral disc and hyperosteogeny of the cervical vertebrae. This hyperplastic substance may stimulate and give rise to oppression to the surrounding spinal cord, nerve roots, blood vessels and sympathetic nerves, resulting in a series of symptoms as numbness, pain, etc. in the neck, shoulder and the upper limbs. The cervical vertebra of the human spine is smallest in the size, weakest in the strength, higher in the motor range and frequency, and bigger in the bearing of per unit area. Along with the increasing of people's age and the accumulated aftereffect of chronic and acute injury, the pulpiform nucleus of the cervical intervertebral disc presents retrograde affection, dehydration, bulge and rupture of the fibrous ring, narrowing of the intervertebral space, and reduction in the stability of cervical vertebrae due to injury and slackening of intervertebral ligaments to stretch and to induce compression upon periosteum. All these changes may lead to break of blood vessels to cause bleeding and hematoma. With the organization of hematoma and calcium salt deposit, osteophyte is formed at last. When the protruded intervertebral disc and hyperplastic osteophyte stimulate and oppress the surrounding spinal nerve root, vertebral artery or spinal cord, the resultant injury, aseptic inflammation, reactions after renovation, etc. will generate a series of clinical symptoms of cervical spondylopathy. In Western medicine, there are five types of cervical spondylopathy including stiff-neck type, nerve root type, spinal cord type, vertebral artery type and sympathetic nerve type. The stiff-neck type, nerve root type and vertebral artery type will be introduced in this article.

  17. Scintigraphic diagnosis of sport injuries: Multiple fractures of ribs by golf-players

    International Nuclear Information System (INIS)

    Three untrained golf-players suffered from pain in the dorsal region of the left thorax after some training hours. Three to four weeks after the pains had begun serial fractures of ribs were diagnosed by sup(99m)Tc-MDP bonescan-examinations. All fractures were localized near the costal angulus (paravertebral) of these ribs. The fractures are caused by manual tensions. The difficulties in timing the bone-scan and in identifying the morphologic substrate are demonstrated. It is recommended, that golf-players suffering from thoracic pain ought to be examined by bone scan. (orig.)

    Fokin, Alexander A; Robicsek, Francis

    2002-12-01

    Poland's syndrome is a rare congenital anomaly characterized by unilateral chest wall hypoplasia and ipsilateral hand abnormalities. Literary data suggest its sporadic nature. The prevailing theory of its cause is hypoplasia of the subclavian artery or its branches, which may lead to a range of developmental changes. The incidence of Poland's syndrome varies between groups (male versus female patients, congenital versus familial cases, and so on) and ranges from 1 in 7,000 to 1 in 100,000 live births. Cases of Poland's syndrome associated with leukemia, carcinoma of the hypoplastic breast, and other conditions, confirm the relationship between developmental defects and tumors, and require oncologic awareness. Various manifestations, age, and gender require different surgical approaches. Our experience, which includes 27 patients (15 male, 12 female), 20 of whom (12 male, 8 female) underwent operation, suggests that the repair should be done in two stages in children and in a single stage in adults. Reconstruction and/or stabilization of the aplastic ribs may be achieved using bone grafts or prosthetic mesh. Muscle flaps and breast implants may be used to correct muscle deficiency and breast hypoplasia and to help achieve a complete cosmetic repair. PMID:12643435

  13. Rib fracture after stereotactic radiotherapy for primary lung cancer: prevalence, degree of clinical symptoms, and risk factors

    International Nuclear Information System (INIS)

    As stereotactic body radiotherapy (SBRT) is a highly dose-dense radiotherapy, adverse events of neighboring normal tissues are a major concern. This study thus aimed to clarify the frequency and degree of clinical symptoms in patients with rib fractures after SBRT for primary lung cancer and to reveal risk factors for rib fracture. Appropriate α/β ratios for discriminating between fracture and non-fracture groups were also investigated. Between November 2001 and April 2009, 177 patients who had undergone SBRT were evaluated for clinical symptoms and underwent follow-up thin-section computed tomography (CT). The time of rib fracture appearance was also assessed. Cox proportional hazard modeling was performed to identify risk factors for rib fracture, using independent variables of age, sex, maximum tumor diameter, radiotherapeutic method and tumor-chest wall distance. Dosimetric details were analyzed for 26 patients with and 22 randomly-sampled patients without rib fracture. Biologically effective dose (BED) was calculated with a range of α/β ratios (1–10 Gy). Receiver operating characteristics analysis was used to define the most appropriate α/β ratio. Rib fracture was found on follow-up thin-section CT in 41 patients. The frequency of chest wall pain in patients with rib fracture was 34.1% (14/41), and was classified as Grade 1 or 2. Significant risk factors for rib fracture were smaller tumor-chest wall distance and female sex. Area under the curve was maximal for BED at an α/β ratio of 8 Gy. Rib fracture is frequently seen on CT after SBRT for lung cancer. Small tumor-chest wall distance and female sex are risk factors for rib fracture. However, clinical symptoms are infrequent and generally mild. When using BED analysis, an α/β ratio of 8 Gy appears most effective for discriminating between fracture and non-fracture patients

    2006-01-01

    As a successive and local plastic delormation process, backward ball spinning was applied for the purpose of producing thin-walled tubular parts with longitudinal inner ribs. According to the local plastic deformation theory, the application of yield criterion to the spinning process and the influence of the radial spinning force component on the formability of inner ribs were analyzed. Based on yield criterion and plastic mechanics, the stable flow rude of metal material and forming criteria of the inner ribs were obtained and conformed to the experimental results so as to contribute greatly to improving the ball spinning process and optimizing the process variables, such as the diameter of ball, the reduction in a pass and the wall thickness of tubular blank, which have a significant influence on the formability of the inner ribs. The knowledge of the influence of the process variables such as the diameter of ball, the reduction in a pass and the wall thickness of tubular blank on the spinning process is essential to preventing the quality defects of the spun parts and obtaining the desired spun parts.

    1994-01-01

    Numerical simulations of incompressible turbulent flow through rectangular ducts with one side rib-roughened were performed to determine pressure drop. The "PHOENICS " software package was used for the computations, which required provision of a wall function for transverse rib-roughened surfaces. The present study was conducted in the range of 10(exp 5) less than or equal to Reynolds number less than or equal to 10(exp 7), 0.01 less than or equal to rib height to hydraulic diameter ratio less than or equal to 0.04, 10 less than or equal to pitch to rib height ratio less than or equal to 40. Using the numerical results, friction factor charts for various aspect ratios were generated. The numerical results agreed well with experimental data that was obtained for 10(exp 5) less than Reynolds less than 2 x 10(exp 5). In addition, a scheme for predicting friction factor using existing correlations for smooth and rough walls was developed.

    1997-08-01

    The effects of ovariectomy on the aged beagle skeleton were studied by histomorphometric analysis of the cortical bone in sequential rib biopsies. Biopsies were taken from each ovariectomized (OV) or sham-operated (SO) dog at the time of surgery and at 1, 4, and 8.5 months after surgery. Tetracycline, calcein, and xylenol orange, respectively, were administered by a fluorochrome labeling procedure (2d-10d-2d) just prior to each postoperative biopsy to provide markers of bone formation. Analysis of sequential biopsies provided a means to follow the response to ovariectomy over time and compare each animal against its own baseline. Examination of sequential biopsies indicated that cortical porosity increased by the fourth month after ovariectomy and remained high at 8.5 months. Ovariectomy did not influence histomorphometric indices at one month after surgery, but substantial differences were observed at later times. Ovariectomy stimulated a transient increase in bone formation and was increased six-fold over that of SO dogs at four months. Ribs were also analyzed for mineral content at necropsy. The rib was heterogeneous along its length for calcium content and concentration. In the midrib where biopsies for histomorphometric analysis were taken, ovariectomy induced a decrease in mass and mineral content; total calcium was decreased by approximately 31%. These data demonstrate that the rib cortical bone is a responsive site for the effects of ovariectomy in female dogs.

    Computer-aided Diagnosis (CAD) systems can assist radiologists in several diagnostic tasks. Lung segmentation is one of the mandatory steps for initial detection of lung cancer in Posterior-Anterior chest radiographs. On the other hand, many CAD schemes in projection chest radiography may benefit from the suppression of the bony structures that overlay the lung fields, e.g. ribs. The original images are enhanced by an adaptive contrast equalization and non-linear filtering. Then an initial estimation of lung area is obtained based on morphological operations and then it is improved by growing this region to find the accurate final contour, then for rib suppression, we use oriented spatial Gabor filter. The proposed method was tested on a publicly available database of 247 chest radiographs. Results show that this method outperformed greatly with accuracy of 96.25% for lung segmentation, also we will show improving the conspicuity of lung nodules by rib suppression with local nodule contrast measures. Because there is no additional radiation exposure or specialized equipment required, it could also be applied to bedside portable chest x-rays. In addition to simplicity of these fully automatic methods, lung segmentation and rib suppression algorithms are performed accurately with low computation time and robustness to noise because of the suitable enhancement procedure.

  6. Detection of rib fractures in an abused infant using digital radiography: a laboratory study

    International Nuclear Information System (INIS)

    To assess the diagnostic performance of digital radiography using charge-coupled device (CCD) technology in the detection of rib fracture in infant abuse.Materials and methods. Four fractured posterior rib arcs and eight normal ribs removed at autopsy from a 10-month-old abused infant were radiographed using a CCD prototype, four clinical film-screen systems, and direct-exposure film. Each rib was viewed with these six systems in nine different projections. The resultant 648 images were assessed for probability of fracture (0-100%) by four pediatric radiologists. The calculated area under the resultant ROC curves (Az) for the CCD was compared with those obtained with direct-exposure, high-detail, medium and fast film-screen radiographic systems. The mean Az for the CCD (0.937) fell within the range of the high-detail systems (0.934-0.940) and was significantly higher (p20 line pairs per millimeter) the CCD performance was comparable (Az=0.944 vs. 0.937). The similar performance can be explained by the higher contrast resolution of the digital technology. This study indicates that in the ex vivo setting, digital radiology can perform comparably to high-detail film-screen imaging. The findings suggest that digital radiography has the potential to replace film-screen imaging in the evaluation of inflicted skeletal injury in infants. (orig.)

    2004-01-01

    As a successively and locally plastic deformation process, ball backward spinning is applied for the purpose of producing thin-walled tubular parts with longitudinal inner ribs. By simplifying ball backward spinning as forward extrusion mechanics model, slab method is used in order to solve spinning force. Based on plastic mechanics, the influence of the process parameters involved on formability of inner ribs as well as the quality defects of spun parts is analyzed so as to present an approach to acquire the desired parts. The quality of inner ribs is one of the critical tasks in obtaining the desired spun workpieces and the height of inner rib depends greatly on spinning material,ball diameter, feed ratio, and wall thickness of tubular blank. The knowledge of the influence of process variables such as ball diameter, feed ratio, and wall thickness of tubular blank on the spinning process is essential to prevent the quality defects of the spun parts and obtain the desired spun parts.

  12. Weakness of the neck extensors, possible causes and relation to adolescent idiopathic cervical kyphosis.

    Science.gov (United States)

    Xiaolong, Shen; Xuhui, Zhou; Jian, Chen; Ye, Tian; Wen, Yuan

    2011-09-01

    Cervical kyphosis may be congenital, or occur as a result of laminectomy, post-traumatic deformity, infection, neuromuscular disorders such as muscular dystrophies, motor neuron disorders such as amyotrophic lateral sclerosis, tumor, and inflammation such as ankylosing spondylitis. Furthermore, adolescent idiopathic cervical kyphosis was defined as cervical kyphotic deformity of adolescent patient without any cause such as those previously described. As no standard values for "cervical kyphosis" could be found in the literature, many reported studies only report a subjective classification, "kyphotic, straight or lordotic". But this method had proven to be unreliable. Grob et al. defined "straight" for the global curvature as +4° to -4°, and lordotic and kyphotic as +4°, respectively. The etiology and pathogenesis of adolescent idiopathic cervical kyphosis remain little understood. Weakness of the neck extensors can result in "dropped head syndrome", a rare disorder characterized by weakness of neck extensor muscles causing an inability to extend the neck and resulting in a chin-on-chest deformity. The purpose of this paper is to propose a possible mechanical cause leading to the kyphotic deformity. We hypothesize that weakness of the neck extensors could be the initiating factor for adolescent idiopathic cervical kyphosis.

  13. Clinical significance of conventional rib series in patients with minor thoracic trauma

    International Nuclear Information System (INIS)

    Background: Conventional rib series (RS) represent a dedicated radiographic technique to visualize the bony parts of the chest wall. The method is commonly used to evaluate minor thoracic trauma, frequently in combination with chest radiographs (CRs). The aim of this study is to asses the clinical relevance of rib fractures diagnosed by RS in minor thoracic trauma. Methods: Retrospective study of 669 patients who received RS for the evaluation of minor thoracic trauma. 405 of the 669 patients received an additional CR. Radiological reports were classified into fracture versus no fracture. Patients were divided into four groups depending on the clinical follow-up. The findings of RS and CR were analyzed using the McNemar test. The statistical significance between the results of the radiographic examinations and the clinical follow-up was analyzed by the Chi-Square test and the Kruskal-Wallis test. Results: We included 669 patients (61.4% men, 38.6% women, median age: 51 years, range: 13-92 years). Analyzing the reports of 669 patients who received RS, 157 (23.5%) patients were diagnosed with at least one fractured rib while no fracture was found in 512 (76.5%) patients. Considering the 157 patients with fractured ribs, 73 (46.8%) had a single fracture, 38 (24.4%) and two fractures and 45 (28.8%) had more than two fractures. When assessing the 405 CRs, we detected 69 (17%) fractures while the corresponding RS of the same patients revealed 87 (21.5%) fractures (p < 0.05). Concerning all patients with rib fractures, 63.1% received medical therapy, while 64.5% of those patients without a radiologically documented fracture also received therapy (p = 0.25). Conclusion: Our results suggest a limited clinical value of detected rib fractures based on RS. Despite being superior compared to CR in diagnosing rib fractures, the results from RS seem to have no significant influence on further clinical management and therapeutic measures. Minor thoracic trauma should be evaluated

    Ferris, Daron G.

    2004-05-01

    Cervical cancer is the second most common malignancy in women worldwide. If diagnosed in the premalignant stage, cure is invariably assured. Although the Papanicolaou (Pap) smear has significantly reduced the incidence of cervical cancer where implemented, the test is only moderately sensitive, highly subjective and skilled-labor intensive. Newer optical screening tests (cervicography, direct visual inspection and speculoscopy), including fluorescent and reflective spectroscopy, are fraught with certain weaknesses. Yet, the integration of optical probes for the detection and discrimination of cervical neoplasia with automated image analysis methods may provide an effective screening tool for early detection of cervical cancer, particularly in resource poor nations. Investigative studies are needed to validate the potential for automated classification and recognition algorithms. By applying image analysis techniques for registration, segmentation, pattern recognition, and classification, cervical neoplasia may be reliably discriminated from normal epithelium. The National Cancer Institute (NCI), in cooperation with the National Library of Medicine (NLM), has embarked on a program to begin this and other similar investigative studies.

    Reiter's syndrome (RS) is a major rheumatic disease, which is frequently chronic, often difficult to treat, and can cause significant, longterm morbidity. To date, there is no specific diagnostic test for RS. Therefore diagnosis has to be made by clinical acumen. Because of the venereal origin of most cases of RS, urethritis and/or cervicitis are often found. If absent, a thorough search should be made for other extra-articular features, e.g., diarrhea, conjunctivitis and mucocutaneous lesion...

    Kothe, R; Wiesner, L; Rüther, W

    2004-08-01

    The rheumatoid involvement of the cervical spine can be divided into three phases. In the early stage of the disease there is an isolated atlantoaxial subluxation (AAS), followed by vertical instability and subaxial instability. If patients show clear symptoms of cervical myelopathy, which can occur during any stage of the disease, the progression cannot be stopped by conservative treatment, which is of great importance at the beginning of the cervical manifestation. Patient education, physiotherapy and immobilization with a stiff collar can significantly reduce pain. Early and effective DMARD therapy can have a positive effect on the natural history of the disease. In case of progressive instability, cervical myelopathy or severe pain operative treatment is indicated. If there is an isolated AAS, fusion can be restricted to the C1/C2 segment. The Magerl transarticular screw fixation is the preferred technique for stabilization. If there is evidence for vertical instability or severe destruction of the C0/C1 joints, occipital cervical fusion has to be performed. Durin the preoperative planning it is necessary to look for signs of subaxial instability. If this is the case, fusion should include the entire cervical spine. Transoral decompression may be necessary when there is persistent anterior compression of the myelon, typically seen in fixed AAS. Non-ambulatory myelopathic patients are more likely to develop severe surgical complications. Therefore, it is important to avoid the development of severe cervical instability by early surgical intervention. The right timing for surgery is still a matter of controversy. Future prospective randomized trials should address this topic to improve the treatment concept for the rheumatoid patient.

    Brachioradial pruritus is characterized by the presence of pruritus on the lateral aspect of the arms. The etiology of this enigmatic entity is the subject of some debate some authors claim that brachioradial pruritus is a photodermatosis whereas others attribute it to the presence of underlying cervical radiculopathy. In these case reports, we present our experience with brachioradial pruritus and discuss the role of underlying neuropathy in its etiology and that of other types of localized pruritus such as notalgia paresthetica, anogenital pruritus, and burning mouth syndrome.

  2. Data Qualification Report For DTN: MO0012RIB00065.002, Parameter Values For Transfer Coefficients

    International Nuclear Information System (INIS)

    A data-qualification evaluation was conducted on Reference Information Base (RIB) data set MOO0 12RIB00065.002, ''Parameter Values for Transfer Coefficients''. The corroborating data method was used to evaluate the data. This method was selected because it closely matches the literature-review method followed to select parameter values. Five criteria were considered when the corroborating method was used: adequacy of the corroborative literature, sufficiency of value-selection criteria, implementation of the selection criteria, documentation of the process, and whether the analysis was conducted in accordance with applicable quality assurance (QA) procedures. Three criteria were used when a literature review was not conducted: appropriate logic used to select parameters, documentation of the process, and whether the analysis was conducted in accordance with applicable QA procedures. The RIB data item, the associated Analysis and Model Report (AMR), the corroborative literature, and the results of an audit revision O/ICN--0 of the AMR were examined. All calculations and the selection process for all values were repeated and confirmed. The qualification team concluded: (1) A sufficient quantity of corroborative literature was reviewed and no additional literature was identified that should have been considered. (2) The selection criteria were sufficient and resulted in valid parameter values. (3) The process was well defined, adequately documented in the AMR, and correctly followed. (4) The analysis was developed in accordance with applicable QA procedures. No negative findings were documented that resulted in questions about the quality of the data. The qualification team therefore recommends that the qualification status of RIB data set MO0012RIB00065.002 be changed to qualified

    The efficacy of high-intensity focused ultrasound (HIFU) for the treatment of a range of different cancers, including those of the liver, prostate and breast, has been demonstrated. As a non-invasive focused therapy, HIFU offers considerable advantages over techniques such as chemotherapy and surgical resection in terms of reduced risk of harmful side effects. Despite this, there are a number of significant challenges which currently hinder its widespread clinical application. One of these challenges is the need to transmit sufficient energy through the rib cage to induce tissue necrosis in the required volume whilst minimizing the formation of side lobes. Multi-element random-phased arrays are currently showing great promise in overcoming the limitations of single-element transducers. Nevertheless, successful treatment of a patient with liver tumours requires a thorough understanding of the way in which the ultrasonic pressure field from a HIFU array is scattered by the rib cage. In order to address this, a boundary element approach based on a generalized minimal residual (GMRES) implementation of the Burton-Miller formulation was used in conjunction with phase conjugation techniques to focus the field of a 256-element random HIFU array behind human ribs at locations requiring intercostal and transcostal treatment. Simulations were carried out on a 3D mesh of quadratic pressure patches generated using CT scan anatomical data for adult ribs 9-12 on the right side. The methodology was validated on spherical and cylindrical scatterers. Field calculations were also carried out for idealized ribs, consisting of arrays of strip-like scatterers, demonstrating effects of splitting at the focus. This method has the advantage of fully accounting for the effect of scattering and diffraction in 3D under continuous wave excitation.

    2014-04-01

    High intensity focused ultrasound (HIFU) enables highly localised, non-invasive tissue ablation and its efficacy has been demonstrated in the treatment of a range of cancers, including those of the kidney, prostate and breast. HIFU offers the ability to treat deep-seated tumours locally, and potentially bears fewer side effects than more established treatment modalities such as resection, chemotherapy and ionising radiation. There remains however a number of significant challenges which currently hinder its widespread clinical application. One of these challenges is the need to transmit sufficient energy through the ribcage to ablate tissue at the required foci whilst minimising the formation of side lobes and sparing healthy tissue. Ribs both absorb and reflect ultrasound strongly. This sometimes results in overheating of bone and overlying tissue during treatment, leading to skin burns. Successful treatment of a patient with tumours in the upper abdomen therefore requires a thorough understanding of the way acoustic and thermal energy is deposited. Previously, a boundary element (BE) approach based on a Generalised Minimal Residual (GMRES) implementation of the Burton-Miller formulation was developed to predict the field of a multi-element HIFU array scattered by human ribs, the topology of which was obtained from CT scan data [1]. Dissipative mechanisms inside the propagating medium have since been implemented, together with a complex surface impedance condition at the surface of the ribs. A reformulation of the boundary element equations as a constrained optimisation problem was carried out to determine the complex surface velocities of a multi-element HIFU array which generated the acoustic pressure field that best fitted a required acoustic pressure distribution in a least-squares sense. This was done whilst ensuring that an acoustic dose rate parameter at the surface of the ribs was kept below a specified threshold. The methodology was tested at an

    2008-06-01

    Full Text Available This work aimed to verify if swimmers present better chest wall coordination during breathing than healthy non-athletes analyzing the correlation between ribs motion and the variation of thoracoabdominal volumes. The results of two up-to-date methods based on videogrammetry were correlated in this study. The first one measured the volumes of 4 separate compartments of the chest wall (superior thorax, inferior thorax, superior abdomen and inferior abdomen as a function of time. The second calculated the rotation angle of the 2nd to the 10th ribs around the quasi-transversal axis also in function of time. The chest wall was represented by 53 markers, attached to the ribs, vertebrae, thorax and abdomen of 15 male swimmers and of 15 non- athletes. A kinematical analysis system equipped with 6 digital video cameras (60Hz was used to obtain the 3D coordinates of the markers. Correlating the curves of ribs rotation angles with the curves of the separate volumes, swimmers presented higher values than non-athletes when the superior and inferior abdomen were considered and the highest correlation values were found in swimmers for the inferior thorax. These results suggest a better coordination between ribs motion and thoracoabdominal volumes in swimmers, indicating the prevalent and coordinated action of the diaphragm and abdominal muscles to inflate and deflate the chest wall. The results further suggest that swimming practice leads to the formation of an optimized breathing pattern and can partially explain the higher lung volumes found in these athletes reported in literature.

    Turbulent forced convective heat transfer and flow configurations in a square channel with wavy-ribs inserted diagonally are examined numerical y. The influences of the 30° and 45° flow attack angles for wavy-ribs, blockage ratio, RB=b/H=0.05–0.25 with single pitch ratio, RP=P/H=1 are investigated for the Reynolds number based on the hydraulic diameter of the square channel, Re=3000–20000. The use of the wavy-ribs, which inserted diagonal in the square channel, is aimed to help to improve the thermal performance in heat exchange systems. The finite volume method and SIMPLE algorithm are applied to the present numerical simulation. The results are presented on the periodic flow and heat transfer profiles, flow configurations, heat transfer characteristics and the performance evaluations. The mathematical results reveal that the use of wavy-ribs leads to a higher heat transfer rate and friction loss over the smooth channel. The heat transfer enhancements are around 1.97–5.14 and 2.04–5.27 times over the smooth channel for 30° and 45° attack angles, respectively. However, the corre-sponding friction loss values for 30° and 45° are around 4.26–86.55 and 5.03–97.98 times higher than the smooth square channel, respectively. The optimum thermal enhancement factor on both cases is found at RB=0.10 and the lowest Reynolds number, Re=3000, to be about 1.47 and 1.52, respectively, for 30° and 45° wavy-ribs.

    1990-03-01

    The ability of magnetic resonance (MR) imaging to demonstrate cervical incompetence in nonpregnant women was investigated in a prospective study of 41 volunteers referred in random order. These included 20 patients with normal cervices, 11 with cervical incompetence of traumatic or congenital origin, and 10 with clinically small cervices due to in utero diethylstilbestrol (DES) exposure. On MR images of the normal patients, cervical length was 33.0 mm +/- 1.0 (mean +/- standard error of the mean) and the width of the internal cervical os was 3.3 mm +/- 0.1. In patients with cervical incompetence, the cervical length did not significantly differ from those in the normal group. However, the internal cervical os was significantly wider (4.5 mm +/- 0.3, P less than .001), and localized irregularity of the endocervical canal was demonstrated in two patients. The MR appearance of the cervical stroma varied from normal, uniformly low signal intensity (n = 4) to uniformly (n = 3) or partially (n = 4) medium-to-high signal intensity on T2-weighted images. In the patients with in utero DES exposure, the mean length of the cervical canal (22.9 mm +/- 1.7) was significantly shorter than that of the normal group. The width of the internal cervical os and the MR signal intensity of the cervical stroma were normal. In summary, MR findings of a cervical length shorter than 3.1 mm (95% confidence limit), an internal cervical os wider than 4.2 mm (95% confidence limit), or abnormal signal intensity in the cervical stroma are highly suggestive of incompetent cervix and should assist in planning further therapeutic decisions.

  17. The LKB1 tumor suppressor differentially affects anchorage independent growth of HPV positive cervical cancer cell lines

    International Nuclear Information System (INIS)

    Infection with high-risk human papillomaviruses is causally linked to cervical carcinogenesis. However, most lesions caused by high-risk HPV infections do not progress to cancer. Host cell mutations contribute to malignant progression but the molecular nature of such mutations is unknown. Based on a previous study that reported an association between liver kinase B1 (LKB1) tumor suppressor loss and poor outcome in cervical cancer, we sought to determine the molecular basis for this observation. LKB1-negative cervical and lung cancer cells were reconstituted with wild type or kinase defective LKB1 mutants and we examined the importance of LKB1 catalytic activity in known LKB1-regulated processes including inhibition of cell proliferation and elevated resistance to energy stress. Our studies revealed marked differences in the biological activities of two kinase defective LKB1 mutants in the various cell lines. Thus, our results suggest that LKB1 may be a cell-type specific tumor suppressor. - Highlights: • LKB1 is a tumor suppressor that is linked to Peutz-Jeghers syndrome. • Peutz-Jeghers syndrome patients have a high incidence of cervical cancer. • Cervical cancer is caused by HPV infections. • This study investigates LKB1 tumor suppressor activity in cervical cancer

    Full Text Available Background: Enlarged palpable cervical lymph nodes as a primary presenting sign are very common and may be due to inflammatory lesions and tumors. Correlation between clinical findings and laboratory data is essential in arriving at a diagnosis. In patients presenting with cervical lymphadenopathy, excision biopsy provides material to establish an early diagnosis. We designed this study in our population for histological evaluation of cervical lymph node biopsies that might be important in the management of these patients. Objective: Histopathological evaluation of different diseases involving the cervical lymph nodes in relation to age and sex of the study population. Materials and Methods: It was a cross sectional study conducted in the department of Pathology, Enam Medical College & Hospital, Savar, Dhaka during the period from January 2006 to December 2010. A total of 107 patients were evaluated for specific cause of cervical lymphadenopathy in relation to age and sex. Lymph node biopsies of all patients of both sexes and all age groups were included in the study. Results: Among the 107 subjects 58 (54.2% were males and 49 (45.8% were females with a male to female ratio of 1.2:1. The age of the patients ranged from 2 to 85 years with a mean age of 32.68 ± 18.01 years. Of the 107 lymph node biopsies, 34 cases (31.8% were reactive lymphadenitis, 41 cases (38.3% were tuberculosis, 2 cases (1.9% were non-caseous granuloma, 6 cases (5.6% were Hodgkin lymphoma, 8 cases (7.5% were non-Hodgkin lymphoma, 12 cases (11.2% were metastatic neoplasm and 4 cases (3.7% were other specific lesions.

    Background Lower cervical dislocation with locked facets is common in cervical injury. The locked facets include unilateral and bilateral types. Different successful closed reduction rates has been achieved between unilateral and bilateral types by using rapid skull traction, which was commonly used to reduce the cervical dislocation. It is important to investigate a suitable management specific to patients with different types of cervical locked facets.Methods A total of 38 patients with cervical dislocation with locked facet due to cervical injury treated by rapid skull traction and operation from 1988 to 2005 were reviewed. Rapid skull traction was used in all the patients. Successful closed reduction rate was 88.0% in patients with bilateral cervical locked facets and that was 15.4% in those with unilateral cervical locked facets. These data were then statistically compared by Chi-square test. Patients who were reduced successfully underwent anterior cervical discectomy and fusion at the injured level, and those who failed in closed reduction received posterior open reduction and fixation.Results In this series, there was statistically significant difference (P<0.05) in the rate of successful closed skull traction reduction between unilateral and bilateral locked facets dislocation. Unilateral cervical locked facets dislocation was not easily reduced by skull traction which was suitable for reduction of bilateral cervical locked facets dislocation. However,unilateral cervical locked facets dislocation can be reduced by posterior open reduction.Conclusions Unilateral cervical locked facets dislocation should be treated immediately with posterior open reduction and instrumentation. Bilateral cervical locked facets dislocation can be reduced by rapid skull traction firstly and anterior cervical discectomy and interbody fusion later.

    ABSTRACT% Purpose: The patients with cleft lip and palate have a higher risk of cervical vertebrae anomalies than do patients in general population. The aim of present study was to determine the prevalence of various upper cervical spine anomalies in different type of clefts. Procedures: Lateral cephalograms of 128 patients (66 males, 62 females) with cleft lip and palate, and 125 (60 males, 65 females) non syndromic patients without cleft lip and palate were selected at random from archive. Cephalograms of the patients were traced and the diagnosis of any cervical vertebrae anomaly was noted. Anomalies were categorized as either: posterior arch deficiency or fusions. Main findings: Prevalence of cervical vertebrae anomalies in the c lef t group was 20. 3% while it was 6.4% in the control group. Further cervical vertebrae anomalies were 16.6% in the CPO group, 19.1% in the BCLP group, and 22.2% in the UCLP group. Conclusion: A higher prevalence of cervical vertebrae anomalies was observed in cleft lip and palate patients. The prevalenc e obser ved is 3 times more in clef t group than c ontrol group.

    Frey syndrome is a common sequela of parotidectomy, and although it is not frequently manifested clinically, it can cause significant morbidity for those affected. Frey syndrome results from synkinetic autonomic reinnervation by transected postganglionic parasympathetic nerve fiber within the parotid gland to the overlying sweat glands of the skin. Many surgical techniques have been proposed to prevent the development of Frey syndrome. For those who develop clinical symptoms of Frey syndrome, objective testing can be performed with a Minor starch-iodine test. Some of the current methods to prevent and treat symptomatic Frey syndrome are reviewed. PMID:26902982

    Cervical spine injuries of children, though rare, have a high morbidity and mortality. The pediatric cervical spine is anatomically and biomechanically different from that of adults. Hence, the type, level and outcome of cervical spine injuries in children are different from those seen in adults. Normal developmental variants seen in children can make evaluation of the pediatric cervical spine challenging. This article reviews the epidemiology of pediatric cervical spine trauma, normal variants seen in children and specific injuries that are more common in the pediatric population. We also propose an evidence-based imaging protocol to avoid unnecessary imaging studies and minimize radiation exposure in children. (orig.)

    Prophylactic or therapeutic arthrodesis is recommended for atlantoaxial instability in Morquio syndrome. Occipitocervical fusion, the common approach for upper cervical fusion in Morquio syndrome sacrifices the movements at the occipitoatlantal joints. The use of C1-C2 transarticular screws for achieving C1-C2 arthrodesis, without compromising mobility at the occipitoatlantal joint in Morquio syndrome has not been reported. We report a case of Morquio syndrome with atlantoaxial instability an...

  11. Improvement of diagnostic confidence for detection of multiple myeloma involvement of the ribs by a new CT software generating rib unfolded images: Comparison with 5- and 1-mm axial images

    International Nuclear Information System (INIS)

    To investigate the performance of a new CT software generating rib unfolded images for improved detection of rib osteolyses in patients with multiple myeloma. One hundred sixteen patients who underwent whole-body reduced-dose multidetector computed tomography (WBRD-MDCT) for multiple myeloma diagnosis and during follow-up were retrospectively evaluated. Nonenhanced CT scans with 5- and 1-mm slice thickness were interpreted by two readers with focus on detection of rib involvement (location, number, fracture). Image analysis of ''unfolded,'' 1-mm-based CT rib images was subsequently undertaken. We classified the number of lytic bone lesions into 0, 1, 2, <5, <10 and ≥10. For all three data sets the reading time was registered. An approximated sum of 6,727 myeloma-related rib lesions was found. On a patient-based analysis, CT (5 mm), CT (1 mm) and CT (1 mm ''unfolded rib'') yielded a sensitivity, specificity and accuracy of 79.7/94.7/87.1, 88.1/93/90.5 and 98.3/96.5/97.4, respectively. In a lesion-based analysis, the sensitivity, specificity and accuracy of the three evaluations were 69.7/87.2/70.5, 79.8/55.9/78 and 96.5/89.7/96.1. Mean reading time for 5 mm/1 mm axial images and unfolded images was 178.7/215.1/90.8 s, respectively. The generation of ''unfolded rib'' images improves detection of rib involvement in patients with multiple myeloma and significantly reduces reading time. (orig.)

    Percutaneous disc decompression procedures have been performed in the past. Various percutaneous techniques such as percutaneous discectomy, laser discectomy, and nucleoplasty have been successful. Our prospective study was directly to evaluate the results of percutaneous cervical nucleoplasty (PCN) surgery for cervical disc herniation, and illustrate the effectiveness of PCN in symptomatic patients who had cervical herniated discs. From July of 2002 to June of 2005, 126 consecutive patients with contained cervical disc herniations have presented at the authors' clinic and treated by PCN. The patients' gender distribution for PCN was 65 male, 61 female. The age of patients ranged from 34 to 66 years (mean 51.9 +/- 10.2 years). The levels of involvement were 21 cases at C3-4, 30 cases at C4-5, 40 cases at C5-6, and 35 cases at C6-7. The clinical outcomes, pain reduction and the segment stability were all recorded during this study. A clinical outcome was quantified by the Macnab standard and using VAS. The angular displacement (AD) > or =11 degrees or horizontal displacement (HD) > or =3 mm was considered to be radiographically unstable. In the results of this study, puncture of the needle into the disc space was accurately performed under X-ray guidance in all cases. There was one case where the Perc-D Spine Wand had broken in the disc space during the procedure. The partial Perc-D Spine Wand, which had broken in the disc space could not be removed by the percutaneous cervical discectomy and thus remained there. There were no recurrent cases or complications in our series. Macnab standard results were excellent in 62 cases, good in 41 cases and fair in 23 cases. The rate of excellent and good was 83.73%. The VAS scores demonstrated statistically significant improvement in PCN at the 2-week, 1, 3, 6, and 12-month follow-up visits when compared to preoperational values (P PCN procedure. There was no significant difference in stability either preoperatively or

    Full Text Available Excellent technologies have been developed to identify the specific microbial agents of chlamydia, gonorrhea, syphilis, herpes, chancroid, trichomoniasis, human papillomavirus and HIV infection. However, it is also crucial to recognize syndromes that may be caused by one or more sexually transmitted pathogens. When laboratory services are lacking or are inadequate to provide timely results to enable appropriate treatment, some patients must be managed and treated syndromically. Most Canadian laboratories should be able to provide diagnostic services to determine the etiology of syndromes such as cervicitis, urethritis, pelvic inflammatory disease, prostatitis, genital ulcers, sexually transmitted infection (STI-related enteric infections, epididymitis, hepatitis, ophthalmia neonatorum, vulvovaginitis and vaginosis.

    In Plummer-Vinson syndrome, esophagography often reveals a web at the anterior wall of the cervical esophagus. The pathogenesis of the esophageal web and the cause of dysphagia in this syndrome were investigated radiographically, endoscopically, manometrically, and histologically. It was considered that the web seen in the esophagogram may have been formed due to the restriction of dilation of the esophageal wall, which results from repetitive inflammation and the subsequent healing process. Dysphagia in this syndrome may be explained by a decrease in swallowing power. Iron deficiency anemia may play the main role in the above histological changes and the resulting decrease in swallowing power.

    The scapulocostal syndrome, a hitherto insufficiently understood condition, was clinically studied in 201 cases. The main findings were: (i) pain was the presenting symptom in all cases and was mainly cervicobrachial (90%); (ii) the syndrome is a definable entity within the wide spectrum of fibromyalgia (fibrositis); (iii) the pain originates mainly from an enthesopathy of the serratus posterior superior muscle; and (iv) physical degeneration was present in 76.5% of patients. Conservative treatment, successful in 95.9% of cases, consisted of an intralesional injection of a steroid-analgesic-mixture of 1 ml Celestone-Soluspan (Scherag) plus 1.8 ml Xylotox E80A (Astra), and physical rehabilitation. It was deducted that the dyskinesia was mainly due to an overload of the scapulocostal articulation, forcing the rib cage down to exert a stretching force on the serratus posterior superior muscle. The operation of 'serratotomy' (severing the serratus posterior superior muscle) was performed with excellent results in 6 patients in whom conservative treatment failed, and is described here for the first time.

    Full Text Available Background: Cervical spondylotic amyotrophy (CSA is a rare clinical syndrome resulting from cervical spondylosis. Surgical treatment includes anterior cervical decompression and fusion (ACDF, and laminoplasty with or without foraminotomy. Some studies indicate that ACDF is an effective method for treating CSA because anterior decompression with or without medial foraminotomy can completely eliminate anterior and/or anterolateral lesions. We retrospectively evaluated outcome of surgical outcome by anterior cervical decompression and fusion (ACDF. Materials and Methods: 28 CSA patients, among whom 12 had proximal type CSA and 16 had distal type CSA, treated by ACDF, were evaluated clinicoradiologically. The improvement in atrophic muscle power was assessed by manual muscle testing (MMT and the recovery rate of the patients was determined on the basis of the Japanese Orthopedic Association (JOA scores. Patient satisfaction was also examined. Results: The percentage of patients, who gained 1 or more grades of muscle power improvement, as determined by MMT, was 91.7% for those with proximal type CSA and 37.5% for those with distal type CSA (P < 0.01. The JOA score-based recovery rates of patients with proximal type and distal type CSA were 60.8% and 41.8%, respectively (P < 0.05. Patient satisfaction was 8.2 for those with proximal type CSA and 6.9 for those with distal type CSA (P < 0.01. A correlation was observed among the levels of improvement in muscle power, JOA score based recovery rate, patient satisfaction and course of disease (P < 0.05. Conclusion: ACDF can effectively improve the clinical function of patients with CSA and result in good patient satisfaction despite the surgical outcomes for distal type CSA being inferior to those for proximal type CSA. Course of disease is the fundamental factor that affects the surgical outcomes for CSA. We recommend that patients with CSA undergo surgical intervention as early as possible.

    Full Text Available Horner‘s syndrome is the triad of miosis, ptosis, and anhidrosis, resulting from disruption of the sympathetic pathways. This article describes an uncommon case of Horner‘s syndrome in a 22-year-old man after blunt trauma to the neck and chest without carotid artery dissection. The patient was brought to the emergency service after motorcycle fall. Neurologic examination revealed a patient presenting the score 15 at Glasgow Coma Scale. The left eyelid was 1-2 mm lower than the right. Carotid Doppler and angiotomography were undertaken and revealed no abnormalities of the carotid artery. CT disclosed a mediastinal hematoma extending to the left apex, compressing the left sympathetic chain. The understanding of this clinical entity may help the surgeon to make a better differential diagnosis in trauma patients in whom prompt diagnosis is critical to stablish the correct treatment.A síndrome de Horner compreende a tríade de miose, ptose e anidrose, resultado de lesão em algum ponto das vias simpáticas. O referido estudo apresenta um caso da referida síndrome em um jovem de 22 anos vitima de queda de moto, com escoriações no tórax e no pescoço, sem dissecção carotídea. Ao exame neurológico, encontrava-se com 15 pontos na Escala de Coma de Glasgow, com miose à esquerda e ptose palpebral ipsilateral. Realizado Doppler de carótidas e angiotomografia dos vasos cérvico-cranianos não sendo evidenciadas anormalidades. A tomografia de tórax mostrou um hematoma no ápice pulmonar esquerdo, comprimindo a cadeia simpática ipsilateral. O conhecimento desta entidade clínica pode ajudar o cirurgião a fazer um diagnóstico diferencial adequado nos pacientes vítimas de traumas, nos quais o diagnóstico correto e eficaz pode ser fundamental para a definição da conduta a ser tomada.

    Full Text Available Abstract Nevoid basal cell carcinoma syndrome (NBCCS, also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs, odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic calcifications, and facial dysmorphism (macrocephaly, cleft lip/palate and severe eye anomalies. Intellectual deficit is present in up to 5% of cases. BCCs (varying clinically from flesh-colored papules to ulcerating plaques and in diameter from 1 to 10 mm are most commonly located on the face, back and chest. The number of BBCs varies from a few to several thousand. Recurrent jaw cysts occur in 90% of patients. Skeletal abnormalities (affecting the shape of the ribs, vertebral column bones, and the skull are frequent. Ocular, genitourinary and cardiovascular disorders may occur. About 5–10% of NBCCS patients develop the brain malignancy medulloblastoma, which may be a potential cause of early death. NBCCS is caused by mutations in the PTCH1 gene and is transmitted as an autosomal dominant trait with complete penetrance and variable expressivity. Clinical diagnosis relies on specific criteria. Gene mutation analysis confirms the diagnosis. Genetic counseling is mandatory. Antenatal diagnosis is feasible by means of ultrasound scans and analysis of DNA extracted from fetal cells (obtained by amniocentesis or chorionic villus sampling. Main differential diagnoses include Bazex syndrome, trichoepithelioma papulosum multiplex and Torre's syndrome (Muir-Torre's syndrome. Management requires a multidisciplinary approach. Keratocysts are treated by surgical removal. Surgery for BBCs is indicated when the number of lesions is limited; other treatments include laser

    The dynamic stability of a cylindrical orthotropic shell reinforced by longitudinal ribs and a hollow cylinder under the action of axial forces changing harmonically with time was investigated with regard for the axial contact interaction of the shell with the ribs. A solution of the differential equations defining this process has been obtained in the form of trigonometric series in the angular and time coordinates. A two-term approximation of the Mathieu-Hill equations of motion was used for construction of the main region of instability of the shell. As a result, the problem was reduced to a system of algebraic equations for components of displacements of the shell at the locations of the ribs. The problem for uniformly spaced ribs was solved in the explicit form. A numerical example of this solution is presented.
