    Idiopathic hypertrophic spinal pachymeningitis (IHSP) is a chronic progressive and diffuse inflammatory fibrosis of the spinal dura mater. Though treatment of IHSP is surgical decompression with steroid therapy, treatment for recurrent IHSP is controversial. Our patient was diagnosed with IHSP based on magnetic resonance imaging (MRI) and underwent laminectomy for decompression following steroid pulse therapy. Despite maintenance of steroid therapy, the patient experienced 3 recurrences. As an alternative immunosuppressant medication, methotrexate was introduced with low-dose steroid. Fortunately, the symptom was resolved, and a decrease of dura thickening was revealed on MRI. We present the case and suggest that methotrexate might be an effective treatment modality for recurrent IHSP.

    A 55-year-old woman with a unique form of chronic hypertrophic pachymeningitis involving the posterior fossa and upper cervical spine is reported. Unlike other cases previously described, the clinical picture was dominated by signs of increased intracranial pressure, lower cranial nerve disorders, and a progressive cervical radiculomyelopathy. The diagnosis was made by means of a contrast-enhanced magnetic resonance imaging scan and confirmed by histological examination of the excised dura. Surgical treatment with removal of the hypertrophic dura provided temporary relief, although the natural history of the disease was not modified. Exhaustive bacteriological and histopathological studies failed to identify a specific cause for this diffuse hypertrophy of the cranial and cervical dura. The literature is reviewed, and other histologically documented cases are discussed.

    Idiopathic hypertrophic pachymeningitis is a rare inflammatory condition with diffuse thickening of the dura mater, which may cause a compressive effect or vascular compromise. We report on a 28-year-old Chinese woman with a history of granulomatous mastitis 7 years previously and oligomenorrhoea, headache, blurred vision, and raised prolactin level 2 years previously, that was diagnosed as prolactinoma and treated conservatively with bromocriptine. However, she had recurrent bilateral vision loss when the bromocriptine was stopped. Her symptoms were resolved by high-dose steroid injection but remained steroid-dependent. Serial magnetic resonance imaging scan showed progressive diffuse thickening of the pachymeningitis with disappearance of pituitary apoplexy. Lumbar puncture showed lymphocytosis with no organisms. Open biopsy of the meninges was performed and histology showed features of inflammatory infiltrates and vasculitis. This is an unusual presentation of a rare condition in this age-group, with co-existing granulomatous mastitis and chronic otitis media, and is a diagnostic challenge mimicking pituitary macroadenoma and meningioma in initial magnetic resonance imaging scans.

    The cervical spine in Chiari I patient with syringomyelia has significantly different anteroposterior diameters than it does in Chiari I patients without syringomyelia. We tested the hypothesis that patients with idiopathic syringomyelia (IS) also have abnormal cervical spinal canal diameters. The finding in both groups may relate to the pathogenesis of syringomyelia. Local institutional review boards approved this retrospective study. Patients with IS were compared to age-matched controls with normal sagittal spine MR. All subjects had T1-weighted spin-echo (500/20) and T2-weighted fast spin-echo (2000/90) sagittal cervical spine images at 1.5 T. Readers blinded to demographic data and study hypothesis measured anteroposterior diameters at each cervical level. The spinal canal diameters were compared with a Mann-Whitney U test. The overall difference was assessed with a Friedman test. Seventeen subjects were read by two reviewers to assess inter-rater reliability. Fifty IS patients with 50 age-matched controls were studied. IS subjects had one or more syrinxes varying from 1 to 19 spinal segments. Spinal canal diameters narrowed from C1 to C3 and then enlarged from C5 to C7 in both groups. Diameters from C2 to C4 were narrower in the IS group (p < 0.005) than in controls. The ratio of the C3 to the C7 diameters was also smaller (p = 0.004) in IS than controls. Collectively, the spinal canal diameters in the IS were significantly different from controls (Friedman test p < 0.0001). Patients with IS have abnormally narrow upper and mid cervical spinal canal diameters and greater positive tapering between C3 and C7. (orig.)

    Full Text Available Hypertrophic pachymeningitis (HP is a rare disorder of diverse etiology. It presents with headaches, cranial neuropathies and ataxia occurring alone or in combination. Dural biopsy is essential to exclude secondary causes of pachymeningitis. There is paucity of data on biopsied cases of HP. We report three biopsy-proven cases of idiopathic hypertrophic cranial pachymeningitis. All our patients had headaches and multiple cranial neuropathies; ataxia was seen in one patient. One patient had recurrent anterior and posterior cranial neuropathies, while one each had recurrent anterior and posterior cranial neuropathies. Two patients had profound irreversible mono-ocular visual loss. All of them showed prominent pachymeningeal thickening on imaging. Infarcts were seen in one patient, which have rarely been documented. All patients showed biopsy evidence of meningeal thickening and nonspecific chronic inflammation of the dura. The disease may have a remitting and relapsing course, and usually responds to steroids. Clinical improvement was excellent in two patients and modest in one on steroid therapy. All our patients required azathioprine during the course of therapy. Early institution and long-term maintenance of steroid therapy prevents neurologic sequelae. Occurrence of abdominal inflammatory pseudotumor in a patient of HP possibly as part of multifocal fibrosclerosis has not been described earlier.

    Postural rehabilitation emphasizing on motor control training of segmental spinal movements has been proposed to effectively reduce the scoliotic spinal deformities in adolescent idiopathic scoliosis (AIS). However, information regarding the impairments of segmental spinal movement control involving segmental spinal stabilizers in adolescent idiopathic scoliosis remains limited. Examination of segmental spinal movement control may provide a window for investigating the features of impaired movement control specific to spinal segments that may assist in the development of physiotherapeutic management of AIS. To compare segmental spinal movement control in adolescents with and without idiopathic scoliosis using modified pressure biofeedback unit. Segmental spinal movement control was assessed in twenty adolescents with idiopathic scoliosis (AISG) and twenty healthy adolescents (CG) using a modified pressure biofeedback unit. Participants performed segmental spinal movements that primarily involved segmental spinal stabilizing muscles with graded and sustained muscle contraction against/off a pressure cuff from baseline to target pressures and then maintained for 1 min. Pressure data during the 1-minute maintenance phase were collected for further analysis. Pressure deviation were calculated and compared between groups. The AISG had significantly greater pressure deviations for all segmental spinal movements of cervical, thoracic, and lumbar spine than the CG. Pressure biofeedback unit was feasible for assessing segmental spinal movement control in AIS. AISG exhibited poorer ability to grade and sustain muscle activities for local movements of cervical, thoracic, and lumbar spine, suggesting motor control training of segmental spinal movements involving segmental spinal stabilizing muscles on frontal, sagittal, and transverse planes were required.

    Blood loss and transfusion requirements during posterior spinal fusion for adolescent idiopathic scoliosis remain a concern. The mechanism of bleeding in these patients is poorly characterized. Thromboelastography is a comprehensive test of a patient's coagulation system commonly used in cardiac surgical procedures. It has not been well studied for use in patients with adolescent idiopathic scoliosis. A prospective, observational study of the coagulation profile of patients with adolescent idiopathic scoliosis undergoing posterior spinal fusion is presented. Healthy patients with adolescent idiopathic scoliosis without a bleeding abnormality were analyzed during posterior spinal fusion. Standard coagulation laboratory and thromboelastogram measures were obtained at the time of the incision and at 1-hour intervals during the surgical procedure. Laboratory values were analyzed in relation to outcomes such as bleeding, transfusion, and a fibrinolysis score. Fifty-eight patients were observed. Eighty-one percent of patients were female, the mean age was 13.5 years, a mean of 11.1 levels were fused, the median estimated blood loss was 645 mL, and 47% of patients received blood products. Overall, laboratory values remained stable throughout the surgical procedure. Mild increases in prothrombin time and partial thromboplastin time were observed, and platelets remained stable. From thromboelastogram analysis, an acceleration of clot formation (decreased reaction time) and a slight increase in clot lysis (increased lysis percentage at 30 minutes) were observed. A fibrinolysis score compiled from the presence of fibrin degradation products, the presence of D-dimers, and increased prothrombin time rose steadily over surgical time. The fibrinolysis score was predictive of both transfusion and greater estimated blood loss per level. The stress of posterior spinal fusion induces a hypercoagulable state in patients with adolescent idiopathic scoliosis. Over the first 2 hours of a

    Full Text Available Primary or idiopathic hypertrophy of the pyloric muscle (IHPM is a rare entity with uncertain pathogenesis which both clinically and pathologically mimics gastric cancer. We present a rare late-occurring case of IHPM in a 71-year-old Caucasian man with no apparent predisposing factor. Imaging studies demonstrated gastric distension with air fluid levels and no evidence of extrinsic compression. At upper endoscopy, massive gastric distension and no evidence of any ulcer or other mucosal defects were observed. Microscopically, marked hypertrophy of muscularis mucosa with smooth muscle cells arranged in whorls and fascicles was present which gradually transitioned to normal areas. The muscle fibers stained with smooth muscle actin and trichrome stain highlighted fibrosis between the muscle fibers. Although uncommon, IHPM can clinically and histologically mimic other proliferations in the gastric wall, such as gastrointestinal stromal tumor or a spindle cell neoplasm. The recent advances in understanding the pathogenesis of IHPM are discussed.

    Full Text Available Aim. To compare the results of surgical correction of spinal deformity in children with idiopathic thoracic scoliosis with the use of transpedicular screw spinal systems with different pedicle screw placement. Material and methods. Thirty-one patients (14–17 years with spinal curvature with a Cobb angle from 40° to 79° were operated on. Surgical correction of the deformity was performed using two methods, depending on the possible placement of a pedicle screw. The first group included 16 patients for whom the transpedicular support elements were placed on both sides, throughout the completely deformed spine. The second group included 15 patients for whom the pedicle screws were not placed for two or more vertebrae on the concave side of the curve, at the top of the main curve. Results. The mean percent correction of the spinal deformity for the first and second groups was 92.5% and 82.6%, respectively. The mean percentage of derotation of the apical vertebra for the first and second groups was 73.9% and 23%, respectively. Conclusion. The use of data based on the anatomical and anthropometric features of the vertebral body with scoliosis facilitates selection of the best option for correction of thoracic curve in children with idiopathic scoliosis using pedicle multi-support metal construction. The use of the spinal pedicle system for correction of spinal deformity in children with idiopathic scoliosis enabled a uniform load distribution along the support elements of the metal construction and maintained the correction in the late postoperative follow-up period.

    Symptomatic anterior or anterolateral dural herniation of the spinal cord is rare, and not uncommonly misdiagnosed, both clinically and radiologically. We present four patients with a radiological diagnosis of herniation of the thoracic spinal cord, and review the current literature. All affected patients have been adults, typcially presenting with long-standing, unexplained sensory symptoms and eventually developing a Brown-Sequard syndrome, with or without motor changes. Herniation occurs in the upper or midthoracic region, between the T2 and T8 levels. (orig.)

    Proprioceptive insoles are known to influence the functions of posture and gait by modulations of the sensory structures at the sole of the foot. Literature has shown that they could improve the position of the upper-body in patients with postural complaints of the musculoskeletal system. The aim of this study was to evaluate the influence of proprioceptive insoles on the spinal curvature in patients with slight idiopathic scoliosis. Eighteen patients were included in this prospective, single-centre, randomized study. All patients needed to have a relevant growth potential and suffered from a slight idiopathic scoliosis. Two groups were used, where group 1 performed physiotherapy twice a week, whereas group 2 was additionally supplied with proprioceptive insoles. Patients underwent three-dimensional rasterstereography for back-shape analysis. Furthermore, a conventional x-ray imaging of the spine was performed at the beginning and 1 year later to document the curvatures. There was no statistical difference in the Cobb angles, and in almost all parameters of the rasterstereography, there was no statistically significant change between and within both groups. According to the results of this study, there was no evidence of any statistical significant effect of proprioceptive insoles on spinal curvature in patients with slight idiopathic scoliosis.

    2003-01-01

    Full Text Available Hypertrophic pachymeningits is an unusual cause of neurological symptoms and is often secondary to infections, carcinomatosis or inflammatory diseases. It may also be idiopathic. We report a case of pachymeningitis which was manifested primarily by psychosis and visual loss with optic atrophy and destruction of nasal septum. The patient, a 45 year old woman was submitted to extensive investigation without evidence of any underlying disease. A meningeal biopsy was performed and showed a mostly unspecific inflammatory process with extensive fibrosis of the dura and few early stage granulomas. These findings suggest either neurosarcoidosis or idiopathic hypertrophic pachymeningitis.

    INTRODUCTION. This paper reports on a radiological evaluation of the outcomes of treatment with the SpineCor brace in children with idiopathic spinal scoliosis vs. a control group who had only received 24 months of rehabilitation. The compliance of the SpineCor-treated patients with medical instructions was also assessed. MATERIAL AND METHODS. A prospective evaluation encompassed a group of forty (40) children, treated with a SpineCor brace for idiopathic scoliosis. A control group included forty (40) children who were followed up. The mean age of the children was 12.0 years and sixty-six (66) of the patients were girls. The study group and the control group were comparable in terms of demographic data and radiological parameters of scoliosis. The mean scoliosis angle was 25.3˚ and 26.1˚ in the thoracic and lumbar spine, respectively. RESULTS. In the (SpineCor-treated) study group, stabilisation or improvement of the scoliosis was obtained in 31 (78%) patients, while progression was noted in 9 (22%). In the control group, stabilisation was found in 21 (53%) patients and progression in 19 (47%), while none of the children met improvement criteria. In the brace-treated group, a smaller change in the thoracic curvature angle was observed (R=0.34, p=0.0001) than in the control group, while no such difference was identified at the lumbar spine level (R=0.15, p=0.18). Out of the 40 treated children, 38 used the brace regularly. Four of the children were active in sports above recreation level. CONCLUSIONS. The treatment of idiopathic spinal scoliosis in children by means of the SpineCor dynamic brace solution significantly more frequently led to stabilisation or correction of scoliosis as measured by Cobb's angle. A high compliance of the children and their parents was also observed.

    Multicenter case-control study. To characterize the pathogenesis of idiopathic spinal epidural lipomatosis (SEL). SEL is often associated with the history of steroid use or endocrine disorders; however, the pathogenesis of idiopathic SEL remains poorly understood. Sixteen patients who underwent lumbar decompression surgery due to severe idiopathic SEL were included in the study (L group, 15 men and 1 woman; mean age, 71.5 yrs). Fifteen patients without SEL, who underwent decompression surgery for lumbar canal stenosis, were selected as controls (C group, 14 men and 1 woman; mean age, 70.3 yrs). The following parameters were analyzed in these two groups: body mass index (BMI), medical history, histology, the size of adipocytes in the epidural fat (EF) tissues, and the expression level of the transcripts for adiponectin, leptin, tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, and IL-8. The mean BMI of the L group was significantly higher than that of the C group (29.1 vs. 25.2 kg/m, P = 0.006), and there was a significant correlation between BMI and the width of EF in both groups. The average adipocyte size in the EF was significantly larger in the L group than in the C group (2846.8 vs. 1699.0 μm, P = 0.017). Furthermore, the expression levels of the transcripts for TNF-α and IL-1β in the L group were significantly higher than those in the C group [2.59-fold increase (P = 0.023) and 2.60-fold increase (P = 0.015), respectively]. Our data suggest that the pathogenesis of idiopathic SEL is associated with obesity. In addition, the increased expression of two major inflammatory cytokines in the EF in the L group may indicate that SEL is causally related to chronic inflammation. 3.

    Patient and surgical factors are known to influence operative blood loss in spinal fusion for adolescent idiopathic scoliosis (AIS), but have only been loosely identified. To date, there are no established recommendations to guide decisions to predonate autologous blood, and the current practice is based primarily on surgeon preference. This study is designed to determine which patient and surgical factors are correlated with, and predictive of, blood loss during spinal fusion for AIS. Retrospective analysis of 340 (81 males, 259 females; mean age, 15.2 y) consecutive AIS patients treated by a single surgeon from 2000 to 2008. Demographic (sex, age, height, weight, and associated comorbidities), laboratory (hematocrit, platelet, PT/PTT/INR), standard radiographic, and perioperative data including complications were analyzed with a linear stepwise regression to develop a predictive model of blood loss. Estimated blood loss was 907±775 mL for posterior spinal fusion (PSF, n=188), 323±171 mL for anterior spinal fusion (ASF, n=124), and 1277±821 mL for combined procedures (n=28). For patients undergoing PSF, stepwise analysis identified sex, preoperative kyphosis, and operative time to be the most important predictors of increased blood loss (Ploss in PSF: blood loss (mL)=C+Op-time (min)×(6.4)-pre-op T2-T12 kyphosis (degrees)×(8.7), C=233 if male and -270 if female. We find sex, operative time, and preoperative kyphosis to be the most important predictors of increased blood loss in PSF for AIS. Mean arterial pressure and operative time were predictive of estimated blood loss in ASF. For posterior fusions, we also present a model that estimates blood loss preoperatively and can be used to guide decisions regarding predonation of blood and the use of antifibrinolytic agents. Retrospective study: Level II.

    Study Design Retrospective cohort study. Purpose The purpose of this study was to evaluate the prevalence of diffuse idiopathic skeletal hyperostosis (DISH) in patients with spinal diseases determined by roentgen images of the whole spine. Overview of Literature Although several studies have investigated the prevalence of DISH in healthy subjects, no detailed data have been reported on the prevalence of DISH in patients with degenerative spinal disorders. Methods Standing whole-spine roentgen images of 345 consecutive patients who underwent surgery in our hospital were obtained. Patients aged Resnick's criteria and Mata's scoring system. The prevalence, location, and numbers of fused vertebral bodies of DISH were recorded. Results DISH was present in 25.6% of patients (72/281). The prevalence of DISH in the 41–49, 50–59, 60–69, 70–79, and ≥80 year age groups was 8.3% (2/24), 9.8% (5/51), 16.0% (12/75), 49.5% (48/97), and 33.3% (4/12), respectively; the prevalence increased with age. The average number of fused vertebral bodies was 7.5. More than 80% of DISH was located from T7 to T11, and more than 95% of DISH was located at T9/10. Patients with DISH were significantly older (71.1 years vs. 60.9 years, p<0.05), and men were more likely to have DISH than women (p<0.05). Conclusions In patients with degenerative spinal diseases with DISH, fused vertebrae were found most frequently in the lower thoracic spine, and their prevalence increased with age. DISH may be an age-related skeletal disorder with a higher overall prevalence in patients with spinal disorders than that in healthy subjects. PMID:28243371

Pre and post-operative anterior-posterior and lateral radiographs of the entire spine were reviewed to assess the changes of cervical sagittal alignment. Thirty-two patients (3 boys, 29 girls) met the inclusion criteria for the study. The average pre-operative cervical sagittal alignment (CSA) was 4.0° ± 12.3° (range -30° to 40°) of lordosis. Postoperatively, the average CSA was 1.7° ± 11.4° (range -24° to 30°). After surgery, it was less than 20° in 27 patients (84.4%) and between 20° and 40° in 5 patients (15.6%). The results of the present study suggest that even if rod precontouring is performed and postoperative thoracic sagittal alignment is restored, improved or remains unchanged after significant correction of the deformity on the frontal plane, the inherent rigidity of the cervical spine limits changes in the CSA as the cervical spine becomes rigid over time.

    Detailed analysis of spinal deformity is important within orthopaedic healthcare, in particular for assessment of idiopathic scoliosis. This paper addresses this challenge by proposing an image analysis method, capable of providing a full three-dimensional spine characterization. The proposed method is based on the registration of a highly detailed spine model to image data from computed tomography. The registration process provides an accurate segmentation of each individual vertebra and the ability to derive various measures describing the spinal deformity. The derived measures are estimated from landmarks attached to the spine model and transferred to the patient data according to the registration result. Evaluation of the method provides an average point-to-surface error of 0.9 mm ± 0.9 (comparing segmentations), and an average target registration error of 2.3 mm ± 1.7 (comparing landmarks). Comparing automatic and manual measurements of axial vertebral rotation provides a mean absolute difference of 2.5° ± 1.8, which is on a par with other computerized methods for assessing axial vertebral rotation. A significant advantage of our method, compared to other computerized methods for rotational measurements, is that it does not rely on vertebral symmetry for computing the rotational measures. The proposed method is fully automatic and computationally efficient, only requiring three to four minutes to process an entire image volume covering vertebrae L5 to T1. Given the use of landmarks, the method can be readily adapted to estimate other measures describing a spinal deformity by changing the set of employed landmarks. In addition, the method has the potential to be utilized for accurate segmentations of the vertebrae in routine computed tomography examinations, given the relatively low point-to-surface error.

    Full Text Available Objectives. This systematic review was conducted to examine the effects of exercise on spinal deformities and quality of life in patients with adolescent idiopathic scoliosis (AIS. Data Sources. Electronic databases, including PubMed, CINAHL, Embase, Scopus, Cochrane Register of Controlled Trials, PEDro, and Web of Science, were searched for research articles published from the earliest available dates up to May 31, 2015, using the key words “exercise,” “postural correction,” “posture,” “postural curve,” “Cobb’s angle,” “quality of life,” and “spinal deformities,” combined with the Medical Subject Heading “scoliosis.” Study Selection. This systematic review was restricted to randomized and nonrandomized controlled trials on AIS published in English language. The quality of selected studies was assessed by the PEDro scale, the Cochrane Collaboration’s tool, and the Grading of Recommendations Assessment, Development, and Evaluation System (GRADE. Data Extraction. Descriptive data were collected from each study. The outcome measures of interest were Cobb angle, trunk rotation, thoracic kyphosis, lumbar kyphosis, vertebral rotation, and quality of life. Data Synthesis. A total of 30 studies were assessed for eligibility. Six of the 9 selected studies reached high methodological quality on the PEDro scale. Meta-analysis revealed moderate-quality evidence that exercise interventions reduce the Cobb angle, angle of trunk rotation, thoracic kyphosis, and lumbar lordosis and low-quality evidence that exercise interventions reduce average lateral deviation. Meta-analysis revealed moderate-quality evidence that exercise interventions improve the quality of life. Conclusions. A supervised exercise program was superior to controls in reducing spinal deformities and improving the quality of life in patients with AIS.

    To compare the diffusion characteristics of idiopathic acute transverse myelitis (ATM) and acute spinal cord infarction (SCI). Diffusion-weighted images (DWI) and an apparent diffusion coefficient (ADC) map were prospectively obtained from patients diagnosed with myelopathy between February 2006 and April 2009. Inclusion criteria included 1) the presence of an intramedullary T2-high signal intensity and 2) a final diagnosis of idiopathic ATM or SCI established by one neurologist. In total, 13 patients (M : F = 8 : 5; mean age, 39.5 years; range, 29-50 years) with idiopathic ATM and seven patients (M : F = 2 : 5; mean age, 58 years; range, 48-75 years) with SCI were included in this study. Two radiologists evaluated the DWIs and ADC map in consensus. The extent of the cord signal change was also evaluated on T2-weighted sagittal images. Among the 16 patients with ATM, 14 patients showed iso-signal on an ADC map, but one case showed restricted diffusion and another showed increased diffusion on the ADC map. Among the seven patients with SCI, five patients showed restricted diffusion. Idiopathic ATM usually does not demonstrate restricted diffusion, which can be a clue to differentiate it from SCI. However, idiopathic ATM with larger segment involvement can show focal diffusion restriction.

    Full Text Available We present the transient long thoracic nerve (LTN injury during instrumented posterior spinal arthrodesis for idiopathic scoliosis. The suspected mechanism of injury, postoperative course and final outcome is discussed. The LTN is susceptible to injury due to its long and relatively superficial course across the thoracic wall through direct trauma or tension. Radical mastectomies with resection of axillary lymph nodes, first rib resection to treat thoracic outlet syndrome and cardiac surgery can be complicated with LTN injury. LTN injury producing scapular winging has not been reported in association with spinal deformity surgery. We reviewed the medical notes and spinal radiographs of two adolescent patients with idiopathic scoliosis who underwent posterior spinal arthrodesis and developed LTN neuropraxia. Scoliosis surgery was uneventful and intraoperative spinal cord monitoring was stable throughout the procedure. Postoperative neurological examination was otherwise normal, but both patients developed winging of the scapula at 4 and 6 days after spinal arthrodesis, which did not affect shoulder function. Both patients made a good recovery and the scapular winging resolved spontaneously 8 and 11 months following surgery with no residual morbidity. We believe that this LTN was due to positioning of our patients with their head flexed, tilted and rotated toward the contralateral side while the arm was abducted and extended. The use of heavy retractors may have also applied compression or tension to the nerve in one of our patients contributing to the development of neuropraxia. This is an important consideration during spinal deformity surgery to prevent potentially permanent injury to the nerve, which can produce severe shoulder dysfunction and persistent pain.

    OBJECTIVE Dorsal arachnoid webs (DAWs) and spinal cord herniation (SCH) are uncommon abnormalities affecting the thoracic spinal cord that can result in syringomyelia and significant neurological morbidity if left untreated. Differentiating these 2 entities on the basis of clinical presentation and radiological findings remains challenging but is of vital importance in planning a surgical approach. The authors examined the differences between DAWs and idiopathic SCH on MRI and CT myelography to improve diagnostic confidence prior to surgery. METHODS Review of the picture archiving and communication system (PACS) database between 2005 and 2015 identified 6 patients with DAW and 5 with SCH. Clinical data including demographic information, presenting symptoms and neurological signs, and surgical reports were collected from the electronic medical records. Ten of the 11 patients underwent MRI. CT myelography was performed in 3 patients with DAW and in 1 patient with SCH. Imaging studies were analyzed by 2 board-certified neuroradiologists for the following features: 1) location of the deformity; 2) presence or absence of cord signal abnormality or syringomyelia; 3) visible arachnoid web; 4) presence of a dural defect; 5) nature of dorsal cord indentation (abrupt "scalpel sign" vs "C"-shaped); 6) focal ventral cord kink; 7) presence of the nuclear trail sign (endplate irregularity, sclerosis, and/or disc-space calcification that could suggest a migratory path of a herniated disc); and 8) visualization of a complete plane of CSF ventral to the deformity. RESULTS The scalpel sign was positive in all patients with DAW. The dorsal indentation was C-shaped in 5 of 6 patients with SCH. The ventral subarachnoid space was preserved in all patients with DAW and interrupted in cases of SCH. In no patient was a web or a dural defect identified. CONCLUSIONS DAW and SCH can be reliably distinguished on imaging by scrutinizing the nature of the dorsal indentation and the integrity of

    Reliable measurements of spinal deformities in idiopathic scoliosis are vital, since they are used for assessing the degree of scoliosis, deciding upon treatment and monitoring the progression of the disease. However, commonly used two dimensional methods (e.g. the Cobb angle) do not fully capture the three dimensional deformity at hand in scoliosis, of which axial vertebral rotation (AVR) is considered to be of great importance. There are manual methods for measuring the AVR, but they are often time-consuming and related with a high intra- and inter-observer variability. In this paper, we present a fully automatic method for estimating the AVR in images from computed tomography. The proposed method is evaluated on four scoliotic patients with 17 vertebrae each and compared with manual measurements performed by three observers using the standard method by Aaro-Dahlborn. The comparison shows that the difference in measured AVR between automatic and manual measurements are on the same level as the inter-observer difference. This is further supported by a high intraclass correlation coefficient (0.971-0.979), obtained when comparing the automatic measurements with the manual measurements of each observer. Hence, the provided results and the computational performance, only requiring approximately 10 to 15 s for processing an entire volume, demonstrate the potential clinical value of the proposed method.

    We report a case of idiopathic cerebral hypertrophic pachymeningitis accompanying neuromyelitis optica spectrum disorder. No other identifiable cause of pachymeningitis was detected. Corticosteroid therapy was effective for both diseases. Hypertrophic pachymeningitis is closely related to autoimmune inflammatory disease of the central nervous system. This case supports the hypothesis that hypertrophic pachymeningitis can be a rare comorbidity of neuromyelitis optica spectrum disorder.

    2010-06-01

    Full Text Available Abstract Background The curveback lineage of guppy is characterized by heritable idiopathic-type spinal curvature that develops during growth. Prior work has revealed several important developmental similarities to the human idiopathic scoliosis (IS syndrome. In this study we investigate structural and histological aspects of the vertebrae that are associated with spinal curvature in the curveback guppy and test for sexual dimorphism that might explain a female bias for severe curve magnitudes in the population. Methods Vertebrae were studied from whole-mount skeletal specimens of curved and non-curved adult males and females. A series of ratios were used to characterize structural aspects of each vertebra. A three-way analysis of variance tested for effects of sex, curvature, vertebral position along the spine, and all 2-way interactions (i.e., sex and curvature, sex and vertebra position, and vertebra position and curvature. Histological analyses were used to characterize micro-architectural changes in affected vertebrae and the intervertebral region. Results In curveback, vertebrae that are associated with curvature demonstrate asymmetric shape distortion, migration of the intervertebral ligament, and vertebral thickening on the concave side of curvature. There is sexual dimorphism among curved individuals such that for several vertebrae, females have more slender vertebrae than do males. Also, in the region of the spine where lordosis typically occurs, curved and non-curved females have a reduced width at the middle of their vertebrae, relative to males. Conclusions Based on similarities to human spinal curvatures and to animals with induced curves, the concave-convex biases described in the guppy suggest that there is a mechanical component to curve pathogenesis in curveback. Because idiopathic-type curvature in curveback is primarily a sagittal deformity, it is structurally more similar to Scheuermann kyphosis than IS. Anatomical

    Human spinal biomechanics are profoundly complex and not well understood, especially in terms of the dynamic spine function. Translation of biomechanics to disease is difficult, particularly since cause must be separated from effect. Primary dynamics predisposing to the onset of chronic spinal disorders, e.g., adolescent idiopathic scoliosis (AIS) or ankylosing spondylitis (AS), must clearly be differentiated from secondary alterations. This commentary addresses primary biomechanics that may predispose to these idiopathic diseases. A novel hypothesis is proposed, based upon inferences regarding their contrasting muscular dynamics. The hypothesis postulates opposing inherent muscle tonicity in AIS versus AS. Converse degrees of spinal stability may predispose to the respective curvature deformities of AIS and the enthesopathy lesions of AS. One condition is suspected to counter-oppose the other, within a polymorphic spectrum of spinal stability.

    Previous studies show a limited alteration of gait at normal walking speed after spinal fusion surgery for adolescent idiopathic scoliosis (AIS), despite the presumed essential role of spinal mobility during gait. This study analyses how spinal fusion affects gait at more challenging walking speeds. More specifically, we investigated whether thoracic-pelvic rotations are reduced to a larger extent at higher gait speeds and whether compensatory mechanisms above and below the stiffened spine are present. 18 AIS patients underwent gait analysis at increasing walking speeds (0.45 to 2.22m/s) before and after spinal fusion. The range of motion (ROM) of the upper (thorax, thoracic-pelvic and pelvis) and lower body (hip, knee and ankle) was determined in all three planes. Spatiotemporal parameters of interest were stride length and cadence. Spinal fusion diminished transverse plane thoracic-pelvic ROM and this difference was more explicit at higher walking speeds. Transversal pelvis ROM was also decreased but this effect was not affected by speed. Lower body ROM, step length and cadence remained unaffected. Despite the reduction of upper body ROM after spine surgery during high speed gait, no altered spatiotemporal parameters or increased compensatory ROM above or below the fusion (i.e. in the shoulder girdle or lower extremities) was identified. Thus, it remains unclear how patients can cope so well with such major surgery. Future studies should focus on analyzing the kinematics of individual spinal levels above and below the fusion during gait to investigate possible compensatory mechanisms within the spine.

    Clinical studies were carried out in the period of 2003-2006 at the Provincial Children's Rehabilitation Hospital in Ameryka near Olsztyn (Poland). The study involved a group of children and youth exhibiting spinal deformity progression in idiopathic scoliosis (IS) of more than 5° per year according to the Cobb scale. Four hundred and fifty patients between 4 and 15 years of age were divided into three groups (n = 150). Group I and group II received 2-hour and 9-hour lateral electrical surface stimulation (LESS), respectively, whereas group III (control) was treated only with corrective exercises for 30 minutes twice a day. LESS was performed with the use of a battery-operated SCOL-2 stimulator manufactured by Elmech, Warsaw, Poland. The effectiveness of this method was confirmed in the treatment of spinal IS in children and youth, especially when the initial spinal deformity did not exceed 20° according to the Cobb scale. A short-duration electrostimulation (2 hours daily) was found to produce results similar to those obtained after overnight (9 h) electrostimulation. Moreover, the analysis of the Harrington prognostic index F confirms the positive effect of LESS in both groups of patients (2 h and 9 h of LESS).

    Evidence is rapidly accumulating to suggest that general proprioceptive dysfunction might be a major contributing factor in the development of adolescent idiopathic scoliosis (AIS). The innervation of appropriate ligaments which has been shown to be involved in proprioceptive feedback mechanisms, has also been suggested to play a part in this sensory dysfunction. Accordingly, this study compared the innervation characteristics of lateral spinal ligaments from patients with AIS to similar measurements from control subjects. Using an antibody to neurofilament protein, Ruffini corpuscles, small and large nerve bundles, and free nerve endings were identified and their numbers and distribution patterns compared. In the control group, the innervation was found to be symmetrical between left and right sides but was more concentrated in the ventral portion of each ligament. No apparent morphological defect of the innervation was found in the lateral spinal ligaments of the scoliosis patients but the innervation densities of Ruffini corpuscles, single nerve fibres and total neural elements were significantly lower (p<0.01) than those found in normal subjects. These results suggest a possible mechanism for the production of AIS and warrant further study.

The study period was from 2000 to 2005. Radiological outcome was assessed using Cobb angle measurement pre and postoperatively, hence assessing percentage correction. The lower instrumented vertebra was taken as the neutral vertebra and the level was recorded. Functional outcome was determined using the Scoliosis Research Society patient administered questionnaire. All patients were called to the clinic and asked to fill in the form. Those patients who were out of the city were mailed the forms and requested via telephone to complete and return.Results: Of the 20 patients operated on, twelve were female and eight were male. The average age at operation was 12.7 years. The mean Cobb angle was 69° preoperatively and 20° postoperatively, representing a percentage correction of 71%. The average duration of follow-up was 3.6 years. There was one major complication involving neurological injury post-op and two minor complications involving wound infection. The average Scoliosis Research Society score (on a scale of 1–5, with 5 being best for pain was 4.5, self-image was 4.2, functional status was 4.1, mental status was 3.8, and satisfaction was 4.4.

    Full Text Available Although the relevance of understanding spinal kinematics during functional activities in patients with complex spinal deformities is undisputed among researchers and clinicians, evidence using skin marker-based motion capture systems is still limited to a handful of studies, mostly conducted on healthy subjects and using non-validated marker configurations. The current study therefore aimed to explore the validity of a previously developed enhanced trunk marker set for the static measurement of spinal curvature angles in patients with main thoracic adolescent idiopathic scoliosis. In addition, the impact of inaccurate marker placement on curvature angle calculation was investigated.Ten patients (Cobb angle: 44.4±17.7 degrees were equipped with radio-opaque markers on selected spinous processes and underwent a standard biplanar radiographic examination. Subsequently, radio-opaque markers were replaced with retro-reflective markers and the patients were measured statically using a Vicon motion capture system. Thoracolumbar/lumbar and thoracic curvature angles in the sagittal and frontal planes were calculated based on the centers of area of the vertebral bodies and radio-opaque markers as well as the three-dimensional position of the retro-reflective markers. To investigate curvature angle estimation accuracy, linear regression analyses among the respective parameters were used. The impact of inaccurate marker placement was explored using linear regression analyses among the radio-opaque marker- and spinous process-derived curvature angles.The results demonstrate that curvatures angles in the sagittal plane can be measured with reasonable accuracy, whereas in the frontal plane, angles were systematically underestimated, mainly due to the positional and structural deformities of the scoliotic vertebrae. Inaccuracy of marker placement had a greater impact on thoracolumbar/lumbar than thoracic curvature angles. It is suggested that spinal curvature

    Background Many investigators advocate anterior release combined with halo-femoral traction and posterior fusion when treating stiff thoracic curves in patient with adolescent idiopathic scoliosis (AIS).But the anterior operations often induce severe complications.Some surgeons choose posterior-only surgery with halo-femoral traction,posterior wide release and correction.But to the best of our knowledge,there are only rare prospective studies on these posterior-only surgeries for AIS patients who have a rigid curve more than 80° and flexibility less than 35%.@@Methods Sixty-four AIS patients were recruited from September 2006 to June 2009.All patients had rigid curves and underwent spinal correction.They were randomly divided into group A (combined anteroposterior surgery) and group B (posterior-only surgery).Images and scoliosis research society-22 questionnaire (SRS-22) scores were performed praand post-operation and during follow-up visits.The operation time,blood loss,hospital days,and hospital charges were compared between the two groups.@@Results These patients were followed for an average of 37.5 months (range,24-65 months).No serious complications were observed.There were no significant differences between the two groups in gender,age,preoperative radiographic data,or preoperative SRS-22 score.The average operation time,blood loss,hospital days and hospital charges in group B were less than those in group A.The SRS-22 score in group B was better than in group A at post-operation and at final follow-up.@@Conclusions In AIS with a rigid curve more than 80° and flexibility less than 35%,strong halo-femoral traction with wide posterior spinal release and three dimensional spinal correction can provide better SRS-22 scores,comparable curve correction,shorter operation time,less blood loss,shorter hospital stays and lower charges when compared to combined anterior and posterior surgery.

    Flattening of the preimplantation rod contour in the sagittal plane influences thoracic kyphosis (TK) restoration in adolescent idiopathic scoliosis (AIS) surgery. The effects of multilevel facetectomy and screw density on postoperative changes in spinal rod contour have not been documented. This study aimed to evaluate the effects of multilevel facetectomy and screw density on changes in spinal rod contour from before implantation to after surgical correction of thoracic curves in patients with AIS prospectively. The concave and convex rod shapes from patients with thoracic AIS (n = 49) were traced prior to insertion. Postoperative sagittal rod shape was determined by computed tomography. The angle of intersection of the tangents to the rod end points was measured. Multiple stepwise linear regression analysis was used to identify variables independently predictive of change in rod contour (Δθ). Average Δθ at the concave and convex side were 13.6° ± 7.5° and 4.3° ± 4.8°, respectively. The Δθ at the concave side was significantly greater than that of the convex side (P Risser sign (P = 0.032), the preoperative main thoracic Cobb angle (P = 0.031), the preoperative TK angle (P = 0.012), and the number of facetectomy levels (P = 0.007). Furthermore, a Δθ at the concave side ≥14° significantly correlated with the postoperative TK angle (P = 0.003), the number of facetectomy levels (P = 0.021), and screw density at the concave side (P = 0.008). Rod deformation at the concave side suggests that corrective forces acting on that side are greater than on the convex side. Multilevel facetectomy and/or screw density at the concave side have positive effects on reducing the rod deformation that can lead to a loss of TK angle postoperatively. PMID:27564683

    A 73-year-old woman (height : 155 cm, weight : 55 kg) was scheduled to undergo a laparotomic hepatectomy and radiofrequency ablation for hepatocellular carcinoma. Her medical history did not include any relevant conditions such as cardiovascular or neurological disorders. A thoracic epidural catheter was introduced at T8-9 before the induction of anesthesia with intravenous propofol. General anesthesia was maintained with the inhalation of oxygen, air, and desflurane, and the continuous infusion of remifentanil. Several intraoperative episodes of mild hypotension occurred, each of which was successfully treated with intravenous ephedrine, but otherwise her anesthetic course was uneventful, and she recovered from the anesthesia smoothly. Her postoperative pain was well controlled with continuous epidural infusion of levobupivacaine and fentanyl, and she could walk by herself on postoperative day (POD) 1. However, she suffered weakness in her lower extremities on POD2 and subsequently fell into complete paraplegia with sensory loss below the T4 level on POD3. A magnetic resonance imaging scan taken on POD4 showed an idiopathic spinal cord infarction (SCI) involving levels T1 through T4, although no epidural abnormalities, e.g., hematomas, were detected. Immediate treatment with methylprednisolone, ozagrel, and edaravone failed to resolve her symptoms. We suggest that it is of great importance to consider SCI as a differential diagnosis as soon as possible in cases of unanticipated postoperative paraplegia.

    Radiological reproducibility study. To assess intra and interobserver reliability of radiographic measurements for global sagittal balance parameters and sagittal spine curves, including cervical spine. Sagittal spine balance in adolescent idiopathic scoliosis (AIS) is a main issue and many studies have been reported, showing that coronal and sagittal deformities often involve sagittal cervical unbalance. Global sagittal balance aims to obtain a horizontal gaze and gravity line at top of hips when subject is in a static position, involving adjustment of each spine curvature in the sagittal plane. To our knowledge, no study did use a methodologically validated imaging analysis tool able to appreciate sagittal spine contours and distances in AIS and especially in the cervical region. Lateral full-spine low-dose EOS radiographs were performed in 75 patients divided in three groups (control subjects, AIS, operated AIS). Three observers digitally analyzed twice each radiograph and 11 sagittal measures were collected for each image. Reliability was assessed calculating intraobserver Pearson's r correlation coefficient, interobserver intra-class correlation coefficient (ICC) completed with a two-by-two Bland-Altman plot analysis. This measurement method has shown excellent intra and interobserver reliability in all parameters, sagittal curvatures, pelvic parameters and global sagittal balance. This study validated a simple and efficient tool in AIS sagittal contour analysis. It defined new relevant landmarks allowing to characterize cervical segmental curvatures and cervical involvement in global balance.

    Background Idiopathic spinal cord herniation (ISCH) is a rare condition and its pathogenesis remains unclear. The purpose of this case report is to present an ISCH case with dorsal subarachnoid septum suggesting the pathogenesis of ISCH being adhesions from preexisting inflammation. Methods Single case report. Results A 60-year-old woman presented with Brown-Séquard syndrome below the level of T6. Magnetic resonance imaging revealed the thoracic spinal cord was displaced ventrally, and the dorsal subarachnoid space was enlarged and had a septum between the spinal cord and dura mater. Intraoperatively, the dorsal dura mater was seen to be adherent and the subarachnoid septum was identified after durotomy. The inner layer defect of the duplicated dura mater was found in the ventral dura mater, through which the spinal cord had herniated. After releasing the septum, the adhesions around the dura mater, and the hiatus, the spinal cord was reduced. Conclusions The present case indicates that adhesions around the dura mater can be the pathogenesis of ISCH. PMID:25694934

    OBJECTIVE Numerous reports have been published on the effectiveness and safety of correction of the coronal Cobb angle and thoracolumbar sagittal alignment in patients with adolescent idiopathic scoliosis (AIS). Suboptimal sagittal alignment, such as decreased thoracic kyphosis (TK), after corrective surgery, is a possible cause of lumbar or cervical spinal degeneration and junctional malalignment; however, few reports are available on reciprocal changes outside of the fused segments, such as the cervical lordotic angle (CLA). This study aimed to investigate the relationship between the perioperative CLA and other radiographic factors or clinical results in AIS, and to identify independent risk factors of postoperative cervical hyperkyphosis. METHODS A total of 51 AIS patients who underwent posterior spinal fusion with the placement of pedicle screw (PS) constructs at thoracic levels were included in the study. Clinical and radiographic follow-up of patients was conducted for a minimum of 2 years, and the postoperative course was evaluated. The authors measured and identified the changes in the CLA and other radiographic parameters using whole-spine radiography, with the patient in the standing position, performed immediately before surgery, 2 weeks after surgery, and 2 years after surgery. The postoperative cervical hyperkyphosis group included patients whose CLA at 2-year follow-up was smaller than -10°. The reciprocal changes of the CLA and other parameters were also investigated. Univariate and multivariate analyses were conducted to determine the associated risk factors for postoperative cervical hyperkyphosis. RESULTS This study comprised 48 females and 3 males (mean age 16.0 years). The mean follow-up period was 47 months (range 24-90 months). The main coronal thoracic curve was corrected from 54.6° to 16.4°, and the mean correction rate was 69.8% at 2 years. The CLA significantly increased from the mean preoperative measurement (-5.4° ± 14°) to the 2

    Abnormal anthropometry including comparably lower weight and body mass index (BMI) in the adolescent idiopathic scoliosis (AIS) population is increasingly recognised, however, no study has examined postoperative weight loss or its clinical relevance in these relatively thin patients. This study aimed to assess perioperative nutritional status as well as clinically severe involuntary weight loss and its impact on outcomes in patients with AIS undergoing posterior spinal fusion (PSF). A further objective was to compare preoperative anthropometric measurements of the current AIS cohort with healthy controls.

    Full Text Available ABSTRACT Objective: To evaluate the prognostic factors in the treatment of patients diagnosed with adolescent idiopathic scoliosis undergoing spinal fusion by the posterior approach. Methods: The study included 48 patients with idiopathic adolescent scoliosis (43 females and 5 males who underwent spinal fusion by the posterior approach, with an average age at diagnosis of 12 years, and clinical signs of Risser between 3 and 4 at the time of surgery. Clinical and radiographic measurements were performed, the participants answered the SRS-30 questionnaire, and the analysis of the medical record data was performed in two occasions during the preoperative period and at the end of two years of follow-up. Results: All satisfaction measures showed statistically significant change after the procedure (p<0.05 with respect to the radiographic characteristics, except for the lumbar apical vertebral translation (p=0.540 and Cobb L1-L5 (p=0.225. Conclusion: In general, it was found that patients who received surgical treatment were more satisfied with their appearance than those who underwent conservative treatment.

    Full Text Available Abstract Background Comprehensive evaluation of the morphology of the spine and of the whole body is essential in order to correctly manage patients suffering from progressive idiopathic scoliosis. Although methodology of clinical and radiological examination is well described in manuals of orthopaedics, there is deficit of data which clinical and radiological parameters are considered in everyday practise. Recently, an increasing tendency to extend scoliosis examination beyond the measure of the Cobb angle can be observed, reflecting a more patient-oriented approach. Such evaluation often involves surface parameters, aesthetics, function and quality of life. Aim of the study To investigate current recommendations of experts on methodology of evaluation of the patient with spinal deformity, essentially idiopathic scoliosis. Methods Structured Delphi procedure for collecting and processing knowledge from a group of experts with a series of questionnaires and controlled opinion feedback was performed. Experience and opinions of the professionals - physicians and physiotherapists managing scoliosis patients - were studied. According to Delphi method a Meeting Questionnaire (MQ has been developed, resulting from a preliminary Pre-Meeting Questionnaire (PMQ which had been previously discussed and approved on line. The MQ was circulated among the SOSORT experts during Consensus Session on "Measurements" which took place at the Annual Meeting of the Society, totally 23 panellists being engaged. Clinical, radiological and surface topography parameters were checked for agreement. Results 90% agreement or more was reached in 35 items and superior than 75% agreement was reached in further 25 items. An evaluation form was proposed to be used by clinicians and researchers. Conclusion The consensus was reached on evaluation of the morphology of the patient with idiopathic scoliosis, comprising clinical, radiological and, to less extend, surface topography

    Idiopathic thoracic spinal cord herniation (TISCH) is a rare cause of surgically treatable progressive myelopathy. The authors report 3 cases of TISCH diagnosed based on conventional T1- and T2-weighted Spin-Echo (SE) MR images in one case, and T1- and T2-weighted SE images combined with 3D-FIESTA (Fast Imaging Employing Steady state Acquisition) and 2D-Phase-Contrast Cine MR imaging in 2 cases. Conventional MRI findings usually provided the diagnosis. 3D-FIESTA images confirmed it, showing the herniated cord in the ventral epidural space. Moreover, in combination with 2D-Phase Contrast cine technique, it was a sensitive method to for the detection of associated pre- or postoperative cerebrospinal fluid spaces abnormalities.

    Full Text Available Abstract Background Child with mild scoliosis is always a subject of interest for most orthopaedic surgeons regarding progression. Literature described Hueter-Volkmann theory regarding disc and vertebral wedging, and muscular imbalance for the progression of adolescent idiopathic scoliosis. However, many authors reported spontaneous resolution of curves also without any reason for that and the rate of resolution reported is almost 25%. Purpose of this study was to question the role of paraspinal muscle tuning/balancing mechanism, especially in patients with idiopathic scoliosis with early mild curve, for spontaneous regression or progression as well as changing pattern of curves. Methods An observational study of serial radiograms in 169 idiopathic scoliosis children (with minimum follow-up one year was carried. All children with Cobb angle Results Average age was 9.2 years at first visit and 10.11 years at final follow-up with an average follow-up of 21 months. 32.5% (55/169, 41.4% (70/169 and 26% (44/169 children exhibited regression, no change and progression in their curves, respectively. 46.1% of children (78/169 showed changing pattern of their curves during the follow-up visits before it settled down to final curve. Comparing final fate of curve with side of curve and number of curves it did not show any relationship (p > 0.05 in our study population. Conclusion Possible reason for changing patterns could be better explained by the tuning/balancing mechanism of spinal column that makes an effort to balance the spine and result into spontaneous regression or prevent further progression of curve. If this which we called as "tuning/balancing mechanism" fails, curve will ultimately progress.

    Background/Aims Postural instability in patients with normal pressure hydrocephalus (NPH) is a most crucial symptom leading to falls with secondary complications. The aim of the current study was to evaluate the therapeutic effect of spinal tap on postural stability in these patients. Methods Seventeen patients with clinical symptoms of NPH were examined using gait scale, computerized dynamic posturography (CDP), and neuropsychological assessment. Examinations were done before and after spinal tap test. Results The gait score showed a significant improvement 24 h after spinal tap test in all subtests and in the sum score (p < 0.003), while neuropsychological assessment did not reveal significant differences 72 h after spinal tap test. CDP showed significant improvements after spinal tap test in the Sensory Organization Tests 2 (p = 0.017), 4 (p = 0.001), and 5 (p = 0.009) and the composite score (p = 0.01). Patients showed best performance in somatosensory and worst performance in vestibular dominated tests. Vestibular dominated tests did not improve significantly after spinal tap test, while somatosensory and visual dominated tests did. Conclusion Postural stability in NPH is predominantly affected by deficient vestibular functions, which did not improve after spinal tap test. Conditions which improved best were mainly independent from visual control and are based on proprioceptive functions. PMID:27790243

    Full Text Available Abstract Background Halo-femoral traction could gradually improve the coronal and sagittal deformity and restore the trunk balance through the elongation of the spine. The purpose of this retrospective study was to assess the effectiveness of Halo-femoral traction after anterior spinal release in the management of severe idiopathic and congenital scoliosis. Methods Sixty patients with severe and rigid curve treated with anterior spinal release, Halo-femoral traction, and second stage posterior spinal fusion were recruited for this retrospective study. Idiopathic Scoliosis (IS group was 30 patients (23 females and 7 males with mean age of 15.5 years. The average coronal Cobb angle was 91.6° and the mean global thoracic kyphosis was 50.6°. The curve type of these patients were 2 with Lenke 1AN, 4 with Lenke 1A+, 1 with Lenke 1BN, 10 with Lenke 1CN, 3 with Lenke 1C+, 3 with Lenke 3CN, 3 with Lenke 3C+, and 4 with Lenke 5C+. Congenital Scoliosis (CS group included 30 patients (20 females and 10 males with average age of 15.2 years. The average coronal Cobb angle of the main curve before operation was 95.7° and the average thoracic kyphosis was 70.2°. All patients had a minimum 12-month follow-up radiograph (range 12–72 months, mean 38 months. Results The average traction time was 23 days and the average traction weight was 16 kg. Four patients experienced brachial plexus palsy and complete nerve functional restoration was achieved at two months follow-up. For the IS group, the post-operative mean Cobb angle of major curve averaged 40.1° with correction rate of 57.5%. For the CS group, the post-operative mean Cobb angle was 56.5° with average correction rate of 45.2%. The difference in curve magnitude between the IS and CS patients after posterior correction was statistically significant (t = 4.15, p Conclusion Halo-femoral traction was a safe, well-tolerated and effective method for the treatment of severe and rigid scoliosis patients.

    Full Text Available Objective:  To evaluate variations in cerebellar tonsil position after posterior spinal fusion (PSF in neurologically intact patients with adolescent idiopathic scoliosis (AIS.  Methods: We retrospective evaluated 40 patients with AIS and no neurological symptoms that underwent PSF. Anteroposterior and sagittal standing radiographs, and sagittal hindbrain MRI were performed in all patients before and after spinal surgery.  The level of the cerebellar tonsil relative to the magnum foramen was measured according to the method described by Aboulezz (J Comput Assist Tomogr 1985. We evaluate variations in cerebellar tonsil position in relation to spinal correction and spinal elongation after PSF. Results: Mean preoperative magnitude of the curve was 53,15° (SD 10,46° and thoracic kyphosis was 35,42º (SD 12,38°. Mean postoperative values were 7,45º (SD 7,33°  and 27,87º (SD 9,03°, respectively. This represents 86% correction in the coronal plane (p<0.00001 and 25% of kyphosis variation (p<0.00001. The average length of the spine in the coronal plane was 44,5 cm (SD 5,25 cm in preoperative x-rays and 48,27 cm (SD 4,40 cm in postoperative x-rays (p<0.00001.  The average length in the sagittal plane was 50,87 cm (SD 4,47 cm in preoperative x-rays and 55,13cm (SD 3,27 cm in postoperative x-rays (p<0.00001. There was no significant difference in the position of the Cerebellar Tonsil before and after spinal correction (p=0,6042. In 10 (25% of the 40 patients, we observed caudal displacement in cerebellar tonsil position after PSF. Average displacement in these patients was 1,22 mm (range 0.1-2.3 mm. In 21 patients we did not observe any variation and in 2 a cephalic displacement was measured. Conclusions:  In most AIS patients, position of the cerebellar tonsil does not change with PSF. We were not able to find any correlation between curve correction or spine elongation and variations in cerebellar tonsillar position.

    Antibiotics are always considered for surgical site infection (SSI) in adolescent idiopathic scoliosis (AIS) surgery. However, the use of antibiotics often causes the antibiotic resistance of pathogens and side effects. Thus, it is necessary to explore natural products as drug candidates. Chitin Oligosaccharide (COS) has anti-inflammation and anti-bacteria functions. The effects of COS on surgical infection in AIS surgery were investigated. A total of 312 AIS patients were evenly and randomly assigned into control group (CG, each patient took one-gram alternative Azithromycin/Erythromycin/Cloxacillin/Aztreonam/Ceftazidime or combined daily), experiment group (EG, each patient took 20 mg COS and half-dose antibiotics daily), and placebo group (PG, each patient took 20 mg placebo and half-dose antibiotics daily). The average follow-up was one month, and infection severity and side effects were analyzed. The effects of COS on isolated pathogens were analyzed. SSI rates were 2%, 3% and 8% for spine wounds and 1%, 2% and 7% for iliac wound in CG, EG and PG (p antibiotics (p antibiotics dose and antibiotics-caused side effects in AIS patients with spinal fusion surgery by improving antioxidant and anti-inflammatory activities. COS should be developed as potential adjuvant for antibiotics therapies.

    Adolescent idiopathic scoliosis is a complex disease with unclear etiopathogenesis. Systemic and persistent low bone mineral density is an independent prognostic factor for curve progression. The fundamental question of how bone quality is affected in AIS remains controversy because there is lack of site-matched control for detailed analysis on bone-related parameters. In this case-control study, trabecular bone biopsies from iliac crest were collected intra-operatively from 28 severe AIS patients and 10 matched controls with similar skeletal and sexual maturity, anthropometry and femoral neck BMD Z-score to control confounding effects. In addition to static histomorphometry, micro-computed tomography (μCT) and real time-PCR (qPCR) analyses, individual trabecula segmentation (ITS)-based analysis, finite element analysis (FEA), energy dispersive X-ray spectroscopy (EDX) were conducted to provide advanced analysis of structural, mechanical and mineralization features. μCT and histomorphometry showed consistently reduced trabecular number and connectivity. ITS revealed predominant change in trabecular rods, and EDX confirmed less mineralization. The structural and mineralization abnormality led to slight reduction in apparent modulus, which could be attributed to differential down-regulation of Runx2, and up-regulation of Spp1 and TRAP. In conclusion, this is the first comprehensive study providing direct evidence of undefined unique pathological changes at different bone hierarchical levels in AIS. PMID:28054655

    We present the results of correcting a double or triple curve adolescent idiopathic scoliosis using a convex segmental pedicle screw technique. We reviewed 191 patients with a mean age at surgery of 15 years (11 to 23.3). Pedicle screws were placed at the convexity of each curve. Concave screws were inserted at one or two cephalad levels and two caudal levels. The mean operating time was 183 minutes (132 to 276) and the mean blood loss 0.22% of the total blood volume (0.08% to 0.4%). Multimodal monitoring remained stable throughout the operation. The mean hospital stay was 6.8 days (5 to 15). The mean post-operative follow-up was 5.8 years (2.5 to 9.5). There were no neurological complications, deep wound infection, obvious nonunion or need for revision surgery. Upper thoracic scoliosis was corrected by a mean 68.2% (38% to 48%, p scoliosis was corrected by a mean 71% (43.5% to 8.9%, p scoliosis was corrected by a mean 72.3% (41% to 90%, p Scoliosis Research Society Outcomes Questionnaire score improved from a mean 3.6 to 4.6 (2.4 to 4, p scoliosis, an improved thoracic kyphosis and normal global sagittal balance.

    Full Text Available Hypertrophic cardiomyopathy (HCM is the most common genetic cardiovascular disease with many genotype and phenotype variations. Earlier terminologies, hypertrophic obstructive cardiomyopathy and idiopathic hypertrophic sub-aortic stenosis are no longer used to describe this entity. Patients present with or without left ventricular outflow tract (LVOT obstruction. Resting or provocative LVOT obstruction occurs in 70% of patients and is the most common cause of heart failure. The pathology and pathophysiology of HCM includes hypertrophy of the left ventricle with or without right ventricular hypertrophy, systolic anterior motion of mitral valve, dynamic and mechanical LVOT obstruction, mitral regurgitation, diastolic dysfunction, myocardial ischemia, and fibrosis. Thorough understanding of pathology and pathophysiology is important for anesthetic and surgical management.

    OBJECTIVE Recently, minimally invasive scoliosis surgery (MISS) was introduced for the correction of adult scoliosis. Multiple benefits including a good deformity correction rate and fewer complications have been demonstrated. However, few studies have reported on the use of MISS for the management of adolescent idiopathic scoliosis (AIS). The purpose of this study was to investigate the outcome of posterior MISS assisted by O-arm navigation for the correction of Lenke Type 5C AIS. METHODS The authors searched a database for all patients with AIS who had been treated with either MISS or PSF between November 2012 and January 2014. Levels of fusion, density of implants, operation time, and estimated blood loss (EBL) were recorded. Coronal and sagittal parameters were evaluated before surgery, immediately after surgery, and at the last follow-up. The accuracy of pedicle screw placement was assessed according to postoperative axial CT images in both groups. The 22-item Scoliosis Research Society questionnaire (SRS-22) results and complications were collected during follow-up. RESULTS The authors retrospectively reviewed the records of 45 patients with Lenke Type 5C AIS, 15 who underwent posterior MISS under O-arm navigation and 30 who underwent posterior spinal fusion (PSF). The 2 treatment groups were matched in terms of baseline characteristics. Comparison of radiographic parameters revealed no obvious difference between the 2 groups immediately after surgery or at the final follow-up; however, the MISS patients had significantly less EBL (p scoliosis surgery is an effective and safe alternative to open surgery for patients with Lenke Type 5C AIS. Compared with results of the open approach, the outcomes of MISS are promising, with reduced morbidity. Before the routine use of MISS, however, long-term data are needed.

    The aim of this study was to elucidate the characteristics, pathogenesis and treatment strategy of hypertrophic pachymeningitis that is associated with myeloperoxidase anti-neutrophil cytoplasmic antibody (ANCA). We retrospectively investigated clinical, radiological, immunological and pathological profiles of 36 patients with immune-mediated or idiopathic hypertrophic pachymeningitis, including 17 patients with myeloperoxidase-ANCA, four patients with proteinase 3-ANCA, six patients with other immune-mediated disorders, and nine patients with 'idiopathic' variety. Myeloperoxidase-ANCA-positive hypertrophic pachymeningitis was characterized by: (i) an elderly female predominance; (ii) 82% of patients diagnosed with granulomatosis with polyangiitis (previously known as Wegener's granulomatosis) according to Watts' algorithm; (iii) a high frequency of patients with lesions limited to the dura mater and upper airways, developing headaches, chronic sinusitis, otitis media or mastoiditis; (iv) a low frequency of patients with the 'classical or generalized form' of granulomatosis with polyangiitis involving the entire upper and lower airways and kidney, or progressing to generalized disease, in contrast to proteinase 3-ANCA-positive hypertrophic pachymeningitis; (v) less severe neurological damage according to the modified Rankin Scale and low disease activity according to the Birmingham Vasculitis Activity Score compared with proteinase 3-ANCA-positive hypertrophic pachymeningitis; (vi) increased levels of CXCL10, CXCL8 and interleukin 6 in cerebrospinal fluids, and increased numbers of T cells, neutrophils, eosinophils, plasma cells and monocytes/macrophages in autopsied or biopsied dura mater with pachymeningitis, suggesting TH1-predominant granulomatous lesions in hypertrophic pachymeningitis, as previously reported in pulmonary or renal lesions of granulomatosis with polyangiitis; and (vii) greater efficacy of combination therapy with prednisolone and

    Full Text Available Aspects of diagnosis, difficulties in the diagnosis and optimal therapeutic strategies in patient with hypertrophic cardiomyopathy and comorbid conditions such as arterial hypertension, ischemic heart disease, dyslipidemia, diabetes mellitus type 2, stenosis of the left renal artery, obesity are reviewed on the example of clinical case. Hypertrophic cardiomyopathy combined with multimorbidity conditions requires a high-quality medical management, where the main goal is to improve the quality and duration of patient's life. This goal is being achieved by optimizing patient's lifestyle and assigning only the minimum amount of medications. Necessity of careful diagnosis of hypertrophic cardiomyopathy, evaluation of the risk of sudden death and search of optimal treatment in patients with multimorbidity pathology are demonstrated in clinical case.

  16. Adolescent idiopathic scoliosis (AIS), environment, exposome and epigenetics: a molecular perspective of postnatal normal spinal growth and the etiopathogenesis of AIS with consideration of a network approach and possible implications for medical therapy

    Science.gov (United States)

    2011-01-01

    Genetic factors are believed to play an important role in the etiology of adolescent idiopathic scoliosis (AIS). Discordant findings for monozygotic (MZ) twins with AIS show that environmental factors including different intrauterine environments are important in etiology, but what these environmental factors may be is unknown. Recent evidence for common chronic non-communicable diseases suggests epigenetic differences may underlie MZ twin discordance, and be the link between environmental factors and phenotypic differences. DNA methylation is one important epigenetic mechanism operating at the interface between genome and environment to regulate phenotypic plasticity with a complex regulation across the genome during the first decade of life. The word exposome refers to the totality of environmental exposures from conception onwards, comprising factors in external and internal environments. The word exposome is used here also in relation to physiologic and etiopathogenetic factors that affect normal spinal growth and may induce the deformity of AIS. In normal postnatal spinal growth we propose a new term and concept, physiologic growth-plate exposome for the normal processes particularly of the internal environments that may have epigenetic effects on growth plates of vertebrae. In AIS, we propose a new term and concept pathophysiologic scoliogenic exposome for the abnormal processes in molecular pathways particularly of the internal environment currently expressed as etiopathogenetic hypotheses; these are suggested to have deforming effects on the growth plates of vertebrae at cell, tissue, structure and/or organ levels that are considered to be epigenetic. New research is required for chromatin modifications including DNA methylation in AIS subjects and vertebral growth plates excised at surgery. In addition, consideration is needed for a possible network approach to etiopathogenesis by constructing AIS diseasomes. These approaches may lead through screening

    1981-04-01

    This report describes the occurrence of a pheochromocytoma in a middle-aged, black female with a 12-year history of hypertension, and a strong family history of hypertension. In this case, the pheochromocytoma was associated with a subendocardial myocardial infarction and congestive heart failure which occurred in the presence of large, dilated coronary arteries without intraluminal obstructions. The patient also had the murmur and echocardiographic and ventriculographic signs typical of idiopathic hypertrophic subaortic stenosis, which resolved following removal of the tumor and return of the blood pressure to normal. The authors believe this to represent a form of transient physiological hypertrophic subaortic stenosis secondary to a hypercatecholamine state.

    Full Text Available Scar formation is a consequence of the wound healing process that occurs when body tissues are damaged by a physical injury. Hypertrophic scars and keloids are pathological scars resulting from abnormal responses to trauma and can be itchy and painful, causing serious functional and cosmetic disability. The current review will focus on the definition of hypertrophic scars, distinguishing them from keloids and on the various methods for treating hypertrophic scarring that have been described in the literature, including treatments with clearly proven efficiency and therapies with doubtful benefits. Numerous methods have been described for the treatment of abnormal scars, but to date, the optimal treatment method has not been established. This review will explore the differences between different types of nonsurgical management of hypertrophic scars, focusing on the indications, uses, mechanisms of action, associations and efficacies of the following therapies: silicone, pressure garments, onion extract, intralesional corticoid injections and bleomycin.

    Scoliosis refers to curves exceeding 10 degrees observed through posterioanterior direct radiography. In fact, the diagnosis for idiopathic scoliosis is accepted to exclude already available causes. The aim of this paper was to review the etiopathogenesis, classification systems and the treatment management of idiopathic scoliosis. A search in the National Library of Medicine (Pubmed) database using the key words 'idiopathic' and 'scoliosis' was performed. For the literature review, papers concerning the etiopathogenesis, classification and treatment were selected among these articles. A search in the National Library of Medicine (Pubmed) database using the key words 'idiopathic' and 'scoliosis' yielded 4518 articles published between 1947 and 2013. The main hypothesis put forward included genetic factors, hormonal factors, bone and connective tissue anomalies. King, Lenke, Coonrad and Peking Union Medical College (PUMC) classifications were the main classification systems for idiopathic scoliosis. Exercise, bracing and anterior, posterior or combined surgery when indicated are the choices for the treatment. Every idiopathic scoliosis case has to be managed to its own characteristics. It is the post-operative appearance that the surgeons are perhaps the least interested but the adolescent patients the most interested in. The aim of scoliosis surgery is to restore the spine without neurological deficit.

    [Purpose] The purpose of this study was to measure and observe the changes in dynamic plantar pressures when school children carried specific bag loads, and to determine whether improved physical balance after an eight-week spinal stabilization exercise program can influences plantar pressures. [Subjects] The subjects were 10 school students with Cobb angles of 10° or greater. [Methods] Gait View Pro 1.0 (Alfoots, Korea) was were based on to measure the pressure of the participants' feet. Spinal stabilization exercises used TOGU Multi-roll Functional (TOGU, Germany) training. Dynamic plantar pressures were measured with bag loads of 0% no bag and 15% of subjects' body weight. The independent t test was performed to analyze changes in plantar pressures. [Results] The plantar pressure measurements of bag load of 0% of subjects' body weight before and after the spinal stabilization exercise program were not significantly different, but those of two foot areas with a 15% load were statistically significant (mt5, 67.32±24.25 and 51.77±25.52 kPa; lat heel, 126.00±20.46 and 102.08±23.87 kPa). [Conclusion] After performance of the spinal stabilization exercises subjects' overall plantar pressures were reduced, which may suggest that physical balance improved.

    Objective To study the clinical, neuroimaging and histopathological features of IgC4-related idiopathic hypertrophic pachymeningitis (IHP). Methods One case of pathologically confirmed IgG4 - related IHP was reported, and related literature of the clinical, radiological and pathological characteristics of this disease was reviewed. Postoperative specimen was sent to Department of Pathology, Xuanwu Hospital. It was sliced and then stained with HE method and examined by immunohistochemistrical study (S-100, Ki-67, CD20, CD3, IgG, IgG4). Results The case was a 55-year-old male patient with IHP. The clinical manifestations of IHP were variable. The patient firstly presented seizures of epilepsy showing left limb convulsions. Brain contrast - enhanced MRI showed that the pachymenx was partly thickened with line - like or nodular enhancement. Microscopically, meningeal biopsies showed dura mater encephali was thickened and hardened. Under microscope, meningeal biopsies showed abnormal thickening of the pachymenx with fibrous connective tissue hyperplasia and infiltration of many inflammatory cells. Inflammatory cells were mainly composed of lymphocytes and plasmocytes with a small amount of eosinophils. Immunohistochemistrical study showed a large number of lymphocytes with expression of IgG, and a small part with expression of IgG4. The treatment of IgG4 - related IHP with hormones and immunosuppressive agents was effective. Conclusion IHP is a class of unknown etiologic diseases, with dural fibrous inflammatory lesion, and part of the IHP patients may be suffering from IgG4-related IHP.%目的 探讨IgG4相关特发性肥厚性硬脑膜炎的临床表现、影像学及组织病理学特点.方法 回顾分析1例IgG4表达阳性的特发性肥厚性硬脑膜炎患者的临床表现、组织学特征,并复习相关文献.结果 男性患者,55岁.以癫痫发作起病,主要表现为发作性左侧肢体抽搐.MRI增强扫描显示局部硬脑膜增厚,并呈线样或

    Hypertrophic cardiomyopathy is a common inherited heart muscle disorder associated with sudden cardiac death, arrhythmias and heart failure. Genetic mutations can be identified in approximately 60% of patients; these are commonest in genes that encode proteins of the cardiac sarcomere. Similar to other Mendelian diseases these mutations are characterized by incomplete penetrance and variable clinical expression. Our knowledge of this genetic diversity is rapidly evolving as high-throughput DNA sequencing technology is now used to characterize an individual patient's disease. In addition, the genomic basis of several multisystem diseases associated with a hypertrophic cardiomyopathy phenotype has been elucidated. Genetic biomarkers can be helpful in making an accurate diagnosis and in identifying relatives at risk of developing the condition. In the clinical setting, genetic testing and genetic screening should be used pragmatically with appropriate counseling. Here we review the current role of genetic biomarkers in hypertrophic cardiomyopathy, highlight recent progress in the field and discuss future challenges.

Three to four months later she developed hypertrophic scar on her chest and upper limbs. At the same time she developed galactorrhea in both breasts and had a disturbed menstrual cycle four months post-burn. On investigation, we found hyperprolactinemia and no other reasons for the high level of prolactin were detected.She received treatment for both the hypertrophic scar and the severe itching she was experiencing. After seven months, her prolactin level had decreased but had not returned to the normal level. It seems that refractory hypertrophic scar is related to the high level of prolactin in burns patients.

    Full Text Available Abstract Background Restrictive impairment is the commonest reported pulmonary deficit in AIS, which improves following surgical operation. However, exact mechanism of how improvement is brought about is unknown. Dynamic fast breath-hold (BH-MR imaging is a recent advance which provides direct quantitative visual assessment of pulmonary function. By using above technique, change in lung volume, chest wall and diaphragmatic motion in AIS patients before and six months after posterior spinal fusion surgery were measured. Methods 16 patients with severe right-sided predominant thoracic scoliosis (standing Cobb's angle 50° -82°, mean 60° received posterior spinal fusion without thoracoplasty were recruited into this study. BH-MR sequences were used to obtain coronal images of the whole chest during full inspiration and expiration. The following measurements were assessed: (1 inspiratory, expiratory and change in lung volume; (2 change in anteroposterior (AP and transverse (TS diameter of the chest wall at two levels: carina and apex (3 change in diaphragmatic heights. The changes in parameters before and after operation were compared using Wilcoxon signed ranks test. Patients were also asked to score their breathing effort before and after operation using a scale of 1–9 with ascending order of effort. The degree of spinal surgical correction at three planes was also assessed by reformatted MR images and correction rate of Cobb's angle was calculated. Results The individual or total inspiratory and expiratory volume showed slight but insignificant increase after operation. There was significantly increase in bilateral TS chest wall movement at carina level and increase in bilateral diaphragmatic movements between inspiration and expiration. The AP chest wall movements, however, did not significantly change. The median breathing effort after operation was lower than that before operation (p There was significant reduction in coronal Cobb's angle

    The pelvis may be seen as a single vertebra, between the spine and the femurs. The anatomy of this pelvic vertebra has changed with the evolution of species, notably with the transition to bipedalism, with the consequent appearance of lumbar lordosis. The lumbosacral angle, almost non-existent in other mammals, is at its greatest in humans. Pelvic and spinal radiological parameters reflect the sagittal balance of the spine in bipedal humanity. Applications in the management of spinal imbalance are numerous. Arthrogenic or degenerative kyphosis is the stereotypic example of spinal aging. Postoperative flat back following spine surgery is hard to prevent. Scoliosis surgery in adults should now take greater account of the patient's individual sagittal balance, by analyzing the pelvic and spinal parameters. The extent of arthrodeses performed during adolescence to manage idiopathic scoliosis may also induce problems of balance in adulthood if these elements are not taken into account.

    Full Text Available Idiopathic scoliosis (IS is a lifetime condition and is defined as a structural, lateral rotated curvature of the spine of >10° on standing coronal plane radiographs. It should be distinguished from other causes of scoliosis. It can be classified as infantile, juvenile, and adolescent according to age. As a rule of thumb, about 80% of all curves are idiopathic, right convex thoracic, and present in otherwise healthy girls at the beginning of puberty. A family member most commonly detects scoliosis. The structural asymmetry of the spine is best observed by asking the patient to bend forward. IS is often seen in more than one member of a family, but the aetiology remains unknown. Multiple genes are likely to be involved with incomplete penetrance and variable expressivity. Early detection by screening allows for monitoring curve progression and timely initiation of bracing, but school screening is controversial and practises vary worldwide. Most patients have minor scoliosis and treatment is generally not recommended for patients with curves 45°. Scoliosis surgery was not successful until the introduction of Harrington’s instrumentation in the 1960s. Modern instrumentation has evolved from the Cotrel-Dubousset system in the 1980s, and a variety of methods are available today. Although scoliosis may be a burden, long-term studies suggest that a good quality of life is maintained in most patients.

  18. Nonobstructive Hypertrophic Cardiomyopathy Out of the Shadows: Known from the Beginning but Largely Ignored … Until Now.

    Maron, Barry J; Rowin, Ethan J; Maron, Martin S; Braunwald, Eugene

    2017-02-01

    Hypertrophic cardiomyopathy was first recognized as a disease of obstruction to left ventricular outflow, hence, its early names and acronyms such as idiopathic hypertrophic subaortic obstruction. The nonobstructive subset of patients, incapable of developing mechanical impedance to left ventricular outflow at rest or with physiologic exercise, was initially recognized by the Braunwald group at the National Institutes of Health >50 years ago in the preimaging era, and is now recognized as comprising about one-third of hypertrophic cardiomyopathy patients. Nevertheless, until recently, and for 25 years, this substantial patient subset has been largely ignored and incompletely understood in terms of its clinical significance and consequences. However, the newfound interest in nonobstructive hypertrophic cardiomyopathy with recent cohort data permits more robust clarity of this subset, as well as the overall disease spectrum. As a group, patients with nonobstructive disease experience a largely stable clinical course at relatively low risk for progressive heart failure symptoms to New York Heart Association class III/IV in (90%). On the other hand, there is a small but important subgroup of 10% at risk for developing drug-refractory advanced heart failure sufficient to justify consideration for heart transplant as the only definitive treatment option. This recognition closes a significant gap in understanding the natural history of hypertrophic cardiomyopathy, also underscoring that the disease is not uniformly grim but instead consistent with extended longevity, thereby providing many patients with a measure of reassurance.

    2002-01-01

    Full Text Available Hypertrophic pachymeningitis is a unique clinical entity characterised by fibrosis and thickening of the duramater with resulting neurological dysfunction. Three cases of this entity are described. Presenting features were headaches and cranial neuropathies in two patients and predominantly cerebellar dysfunction in the third. One of the patients also had evidence of spinal involvement. Lower cranial nerves were chiefly involved in two patients whereas optic nerve was the predominantly affected nerve in one. Except for the presence of rheumatoid arthritis in one of the patients, we could not document clinical or biochemical evidence of any predisposing infective, inflammatory or infiltrative condition in the other two. All three patients had characteristic changes on imaging suggestive of thickened and enhancing duramater. Although variable steroid responsiveness was seen in all the three patients, tendency towards steroid dependence was evident. The clinical presentations, causes, radiological features, management options and differential diagnosis of this unique clinical syndrome have been discussed.

    Scoliosis is defined as a lateral curvature of the spine greater than 10 degrees on radiography that is typically associated with trunk rotation. The three major types of scoliosis are congenital, idiopathic, and neuromuscular. Idiopathic scoliosis is divided into three subcategories based on the age of onset. Infantile idiopathic scoliosis affects patients younger than 3 years, juvenile idiopathic scoliosis appears in children between 3 and 10 years, and adolescent idiopathic scoliosis (AIS) occurs in skeletally immature patients older than 10 years. AIS is the most common form of idiopathic scoliosis. Approximately 2% to 4% of children aged 10 to 16 years have some degree of spinal curvature. Although some researchers view routine screening for AIS as controversial, well-child examinations and sports physicals are an optimal time to evaluate for AIS in the clinical setting. In 2008, the American Academy of Orthopaedic Surgeons, the Scoliosis Research Society, the Pediatric Orthopaedic Society of North America, and the American Academy of Pediatrics convened a task force to review the issues related to scoliosis screening and issued an information statement concluding that although screening has limitations, the potential benefits that patients with idiopathic scoliosis receive from early treatment can be substantial. Recommendations are now that females are screened twice, at age 10 and 12 years, and males once at age 13 or 14 years. Screening during routine well-child examinations and/or school-based evaluations will help identify patients who need ongoing monitoring. The evaluation of curvatures in conjunction with the level of skeletal maturity will help to guide the management of the curvature.

    Lupus vulgaris is the most common form of cutaneous tuberculosis occurring in previously sensitized individuals with a high degree of tuberculin sensitivity. Various forms including plaque, ulcerative, hypertrophic, vegetative, papular, and nodular forms have been described. A 30-year-old male patient presented with a very large hypertrophic lupus vulgaris lesion over left side of chest since 22 years. Histopathological examination showed granulomatous infiltration without caseation necrosis. The Mantoux reaction was strongly positive. Hypertrophic lupus vulgaris of such a giant size and that too at an unusual site is extremely rare and hence is being reported.

    Full Text Available Introduction. Although fractures of humeral shaft show excellent results with conservative management, nonunion does occur. Case Report. We bring forth the case of a young male with a 1.5-year-old hypertrophic nonunion of the humerus mimicking an enchondroma. The initial X-ray images of the patient appeared to be an enchondroma, which only on further evaluation and histopathological analysis was diagnosed conclusively to be a hypertrophic nonunion. Discussion. Enchondromas are often incidentally diagnosed benign tumours. It is however not common to misdiagnose a hypertrophic nonunion to be an enchondroma. We present this case to highlight the unique diagnostic dilemma the treating team had to face.

    Full Text Available A 33-year-old male patient experienced temporary sensory loss and weakness in the right lower extremity one month prior to admission. The patient was admitted to a private clinic with a three-day history of acute onset of sensory loss and weakness in both lower extremities and was treated and followed up with a prediagnosis of transverse myelitis and the Guillain-Barre syndrome (GBS. The patient was subsequently transferred to our clinic and the neurologic examination revealed paraplegia in both lower extremities, positive bilateral Babinski signs, and hypesthesia below the T10 dermatome with saddle anesthesia. The patient had urinary incontinence and thoracic magnetic resonance imaging (MRI showed an image of a mass compressing the medulla.

    Retrospective. The purpose of this study is to review the efficacy of monitoring data and outcomes in pediatric patients with spinal cord pathology. The incidence of spinal cord pathology in pediatric patients with scoliosis has been reported between 3% and 20%. Previous studies demonstrated that intraoperative spinal cord monitoring (IOM) during scoliosis surgery can be reliable despite underlying pathology. A single-center retrospective review of 119 spinal surgery procedures in 82 patients with spinal cord pathology was performed. Diagnoses included Arnold-Chiari malformation, syringomyelia, myelomeningocele, spinal cord tumor, tethered cord, and diastematomyelia. Baseline neurologic function and history of prior neurosurgical intervention were identified. Outcome measures included ability to obtain reliable monitoring data during surgery and presence of postoperative neurologic deficits. Results were compared for 82 patients with adolescent idiopathic scoliosis (AIS). Usable IOM data were obtained in 82% of cases (97/119). Twenty-two cases (18%) had no lower extremity data. Patients with Arnold-Chiari malformation or syringomyelia pathologies, in isolation or together, had a significantly higher rate of reliable data compared to other pathologies (p < .0001). Among study group cases with usable data, there were 1 false negative (1%) and 4 true positive (4%) outcomes. There were no permanent neurologic deficits. The spinal cord pathology group demonstrated 80% sensitivity and 92% specificity. Spinal cord monitoring is a valuable tool in pediatric patients with spinal cord pathology undergoing spinal deformity surgeries. When obtained, data allow to detect changes in spinal cord function. Patients with a diagnosis of Arnold-Chiari or syringomyelia have monitoring data similar to those patients with AIS. Patients with other spinal cord pathologies have less reliable data, and surgeons should have a lower threshold for performing wake-up tests to assess spinal cord

    Highlights: • Purpose of this review is to address the current concepts on the pathophysiology of discogenic, radicular, facet and dysfunctional spinal pain, focusing on the role of the imaging in the diagnostic setting, to potentially address a correct approach also to minimally invasive interventional techniques. • Special attention will be given to the discogenic pain, actually considered as the most frequent cause of chronic low back pain. • The correct distinction between referred pain and radicular pain contributes to give a more correct approach to spinal pain. • The pathogenesis of chronic pain renders this pain a true pathology requiring a specific management. - Abstract: The spinal pain, and expecially the low back pain (LBP), represents the second cause for a medical consultation in primary care setting and a leading cause of disability worldwide [1]. LBP is more often idiopathic. It has as most frequent cause the internal disc disruption (IDD) and is referred to as discogenic pain. IDD refers to annular fissures, disc collapse and mechanical failure, with no significant modification of external disc shape, with or without endplates changes. IDD is described as a separate clinical entity in respect to disc herniation, segmental instability and degenerative disc desease (DDD). The radicular pain has as most frequent causes a disc herniation and a canal stenosis. Both discogenic and radicular pain also have either a mechanical and an inflammatory genesis. For to be richly innervated, facet joints can be a direct source of pain, while for their degenerative changes cause compression of nerve roots in lateral recesses and in the neural foramina. Degenerative instability is a common and often misdiagnosed cause of axial and radicular pain, being also a frequent indication for surgery. Acute pain tends to extinguish along with its cause, but the setting of complex processes of peripheral and central sensitization may influence its evolution in chronic

Although benign in the majority of patients, the natural course of the disease may result in significant disturbance of body morphology, reduced thoracic volume, impaired respiration, increased rates of back pain, and serious esthetic concerns. Risk of deterioration is highest during the pubertal growth spurt and increases the risk of pathologic spinal curvature, increasing angular value, trunk imbalance, and thoracic deformity. Early clinical detection of scoliosis relies on careful examination of trunk shape and is subject to screening programs in some regions. Treatment options are physiotherapy, corrective bracing, or surgery for mild, moderate, or severe scoliosis, respectively, with both the actual degree of deformity and prognosis being taken into account. Physiotherapy used in mild idiopathic scoliosis comprises general training of the trunk musculature and physical capacity, while specific physiotherapeutic techniques aim to address the spinal curvature itself, attempting to achieve self-correction with active trunk movements developed in a three-dimensional space by an instructed adolescent under visual and proprioceptive control. Moderate but progressive idiopathic scoliosis in skeletally immature adolescents can be successfully halted using a corrective brace which has to be worn full time for several months or until skeletal maturity, and is able to prevent more severe deformity and avoid

    Four cases of idiopathic chondrolysis of the hip in three white girls and one Maori girl are reported. The authors stress the causes why a disease with characteristic clinical and radiographic appearances and normal biochemical findings presents diagnostic difficulties. It is suspected that idiopathic chondrolysis is a metabolic disorder of chondrocytes, triggered by environment circumstances in susceptible individuals. Idiopathic chondrolysis is probably one of the most common causes of coxarthrosis in women.

    Full Text Available A previously unreported variation in the anatomy of the spinal dural sheath was observed during routine cadaveric dissection, consisting of a duplication of the dural layer, with layers adherent throughout their length. The double dural sheath completely enveloped the spinal cord and nerve roots, and extended from C2 to L5: both layers were of similar thickness to a single dural sheath. Duplication of the dura mater in the form of two complete dural sheaths has not been previously observed and/or reported in a cadaveric study. However, areas of localised duplication of the ventral aspect of the dural sheath have been observed during intra-operative dissection, particularly in association with idiopathic herniation of the spinal cord. Complete duplication of the spinal dura mater is of clinical interest in spinal surgery, particularly in relation to idiopathic spinal cord herniation.

    Spinal misalignments are a common reason for consultation at primary care centers and specialized departments. Misalignment has diverse causes and is influenced by multiple factors: in adolescence, the most frequent misalignment is scoliosis, which is idiopathic in 80% of cases and normally asymptomatic. In adults, the most common cause is degenerative. It is important to know the natural history and to detect factors that might predict progression. The correct diagnosis of spinal deformities requires specific imaging studies. The degree of deformity determines the type of treatment. The aim is to prevent progression of the deformity and to recover the flexibility and balance of the body. Copyright © 2016 SERAM. Published by Elsevier España, S.L.U. All rights reserved.

    Idiopathic scoliosis is a complex three-dimensional deformity and in the thoracic region the essential lesion lies in the sagittal plane in the form of an area of inappropriate lordosis. The thoracic kyphosis is normally protected from buckling by being behind the axis of spinal column rotation but when the thoracic lordosis develops it brings the apical region anterior to this axis and thus under compression with resultant buckling failure of the spinal column. The condition of idiopathic thoracic scoliosis is the opposite to idiopathic hyperkyphosis (Scheuermann's disease), the latter being rotationally stable and not moving out of the sagittal plane. The two frequently co-exist in the same spine with thoracic hyperkyphosis above an area of lumbar lordo-scoliosis. There is a spectrum of normal lateral profile and flat backs at the one end are in danger of buckling (lordo-scoliosis) while round backs at the other end of the spectrum are in danger of being defined as Scheuermann's disease. There is no requirement for a specific pathological process. Engineers describe only two ways in which a flexible column can fall into mechanically-angular collapse (kyphosis) and column buckling (lordo-scoliosis). A number of factors favour column buckling (Euler's law) and thus the bigger a deformity the more likely it will be to continue progressing and the taller and more slender the column the more likely it will be to fail and this we see in our patients with idiopathic scoliosis. Not only is lordosis the essential lesion but it is also the primary abnormality which can be demonstrated in children before lateral curvature and rotation develop.

    Apical hypertrophic cardiomyopathy(AHCM) is a relatively rare morphologic variant of HCM in which the hypertrophy of myocardium is localized to the left ventricular apex. Symptoms of AHCM might vary from none to others mimic coronary artery disease including acute coronary syndrome, thus resulting in inappropriate hospitalization. Transthoracic echocardiography is the firstline imaging technique for the diagnosis of hypertrophic cardiomyopathies. However, when the hypertrophy of the myocardium is localized in the ventricular apex might results in missed diagnosis. Aim of this paper is to review the different imaging techniques used for the diagnosis of AHCM and their role in the detection and comprehension of this uncommon disease.

    Background: Ventricular-vascular coupling is an important phenomenon in many cardiovascular diseases. The association between aortic mechanical dysfunction and left ventricular (LV) dysfunction is well characterized in many disease entities, but no data are available on how these changes are related in hypertrophic cardiomyopathy (HCM). Aim of the work: This study examined whether HCM alone is associated with an impaired aortic mechanical function in patients without cardiovascular risk factors and the relation of these changes, if any, to LV deformation and cardiac phenotype. Methods: 141 patients with HCM were recruited and compared to 66 age- and sex-matched healthy subjects as control group. Pulse pressure, aortic strain, stiffness and distensibility were calculated from the aortic diameters measured by M-mode echocardiography and blood pressure obtained by sphygmomanometer. Aortic wall systolic and diastolic velocities were measured using pulsed wave Doppler tissue imaging (DTI). Cardiac assessment included geometric parameters and myocardial deformation (strain and strain rate) and mechanical dyssynchrony. Results: The pulsatile change in the aortic diameter, distensibility and aortic wall systolic velocity (AWS') were significantly decreased and aortic stiffness index was increased in HCM compared to control (P < .001) In HCM AWS' was inversely correlated to age(r = − .32, P < .0001), MWT (r = − .22, P < .008), LVMI (r = − .20, P < .02), E/Ea (r = − .16, P < .03) LVOT gradient (r = − 19, P < .02) and severity of mitral regurg (r = − .18, P < .03) but not to the concealed LV deformation abnormalities or mechanical dyssynchrony. On multivariate analysis, the key determinant of aortic stiffness was LV mass index and LVOT obstruction while the role LV dysfunction in aortic stiffness is not evident in this population. Conclusion: HCM is associated with abnormal aortic mechanical properties. The severity of cardiac

    Background. Hypertrophic osteoarthropathy (HOA) is a syndrome characterized by abnormal proliferation of the skin and bony structures at the distal extremities resulting in digital clubbing, periosteal bony reaction, and joint effusion. It can be primary (idiopathic) without any clear identifiable etiology as well as secondary to variety of systemic diseases most notably lung pathology. Case Presentation. We describe a rare case of primary idiopathic osteoarthropathy in a male patient who presented with severe pain and tenderness in his legs. His history was significant for long standing alcoholism. Physical examination showed severe fingers and toes clubbing. He reported similar changes in his mother. Clinical and radiological findings were remarkable for distal leg tenderness and diffuse periosteal bony reactions, respectively. Computerized tomography scan failed to show any pathology apart from fatty liver infiltration. In the absence of obesity or diabetes, this was consistent with alcoholic steatosis. He was started on nonsteroidal anti-inflammatory drug which dramatically improved his symptoms. Conclusion. Primary hypertrophic osteoarthropathy should be considered in a previously healthy person presenting with bony pain and finger clubbing especially after ruling out the common secondary causes. Moreover, alteration of prostaglandin metabolism secondary to alcoholic consumption might be a contributing factor. PMID:28116207

    Full Text Available Diffuse idiopathic skeletal hyperosteosis (DISH is also known as Forestier disease and is a systemic non-inflammatory disorder seen more commonly in males and elderly. It is characterized by calcification of the anterior longitudinal ligament of the vertebral column and various extraspinal ligaments. It is usually asymptomatic while the most common symptoms are spinal pain, limited range of spinal motion and dysphagia due to esophagus compression. The etiopathogenesis is not clear. It is commonly seen together with diabetes mellitus, obesity, hyperinsulinemia, hypertension and lipid and purine metabolism disorders, indicating an association with metabolic disorders. Recent studies have emphasized that the pathological calcification of the anterior longitudinal ligament plays a role in the pathophysiology. The aim of this study was to summarize new pathogenetic, clinical and therapeutic insights of this disease, based on published literature.

  5. Transcriptional regulation of cardiac genes balance pro- and anti-hypertrophic mechanisms in hypertrophic cardiomyopathy

    Directory of Open Access Journals (Sweden)

    Nina Gennebäck

    2012-06-01

    Full Text Available Hypertrophic cardiomyopathy (HCM is characterized by unexplained left ventricular hypertrophy. HCM is often hereditary, but our knowledge of the mechanisms leading from mutation to phenotype is incomplete. The transcriptional expression patterns in the myocar - dium of HCM patients may contribute to understanding the mechanisms that drive and stabilize the hypertrophy. Cardiac myectomies/biopsies from 8 patients with hypertrophic obstructive cardiomyopathy (HOCM and 5 controls were studied with whole genome Illumina microarray gene expression (detecting 18 189 mRNA. When comparing HOCM myocardium to controls, there was significant transcriptional down-regulation of the MYH6, EGR1, APOB and FOS genes, and significant transcriptional up-regulation of the ACE2, JAK2, NPPA (ANP, APOA1 and HDAC5 genes. The transcriptional regulation revealed both pro- and anti-hypertrophic mechanisms. The pro-hypertrophic response was explained by the transcriptional down-regulation of MYH6, indicating that the switch to the fetal gene program is maintained, and the transcriptional up-regulation of JAK2 in the JAK-STAT pathway. The anti-hypertrophic response was seen as a transcriptional down-regulation of the immediate early genes (IEGs, FOS and EGR1, and a transcriptional up-regulation of ACE2 and HDAC5. This can be interpreted as a transcriptional endogenous protection system in the heart of the HOCM patients, neither growing nor suppressing the already hypertrophic myocardium.

  6. Contractile Dysfunction in Sarcomeric Hypertrophic Cardiomyopathy.

    2016-09-01

    The pathophysiological mechanisms underlying the clinical phenotype of sarcomeric hypertrophic cardiomyopathy are controversial. The development of cardiac hypertrophy in hypertension and aortic stenosis is usually described as a compensatory mechanism that normalizes wall stress. We suggest that an important abnormality in hypertrophic cardiomyopathy is reduced contractile stress (the force per unit area) generated by myocardial tissue secondary to abnormalities such as cardiomyocyte disarray. In turn, a progressive deterioration in contractile stress provokes worsening hypertrophy and disarray. A maintained or even exaggerated ejection fraction is explained by the increased end-diastolic wall thickness producing augmented thickening. We propose that the nature of the hemodynamic load in an individual with hypertrophic cardiomyopathy could determine its phenotype. Hypertensive patients with hypertrophic cardiomyopathy are more likely to develop exaggerated concentric hypertrophy; athletic individuals an asymmetric pattern; and inactive individuals a more apical hypertrophy. The development of a left ventricular outflow tract gradient and mitral regurgitation may be explained by differential regional strain resulting in mitral annular rotation.

    2014-06-01

    Full Text Available Scoliosis is called idiopathic when no other underlying disease can be identified. The etiology of adolescent idiopathic scoliosis (AIS is still unknown despite many years of research effort. Theories on AIS's etiology have included mechanical, hormonal, metabolic, neuromuscular, growth, and genetic abnormalities. Skeletally immature patients with adolescent idiopathic scoliosis are at risk of curve progression. The adolescent onset of severe idiopathic scoliosis has traditionally been evaluated using standing posteroanterior radiographs of the full spine to assess lateral curvature with the Cobb method. Scoliosis in children of school age and above primarily occurs in girls. The therapeutic goal in children is to prevent progression. In children, scoliosis of 20 and deg; or more should be treated with a brace, and scoliosis of 45 and deg; or more with surgery. [Arch Clin Exp Surg 2014; 3(3.000: 174-182

  13. Review of idiopathic pancreatitis

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Recent advances in understanding of pancreatitis and advances in technology have uncovered the veils of idiopathic pancreatitis to a point where a thorough history and judicious use of diagnostic techniques elucidate the cause in over 80% of cases. This review examines the multitude of etiologies of what were once labeled idiopathic pancreatitis and provides the current evidence on each. This review begins with a background review of the current epidemiology of idiopathic pancreatitis prior to discussion of various etiologies. Etiologies of medications, infections, toxins,autoimmune disorders, vascular causes, and anatomic and functional causes are explored in detail. We conclude with management of true idiopathic pancreatitis and a summary of the various etiologic agents. Throughout this review, areas of controversies are highlighted.

    Full Text Available Adolescent idiopathic scoliosis (AIS, the most common pediatric spine problem, is a structural lateral and rotatory curvature of the spine arising in otherwise normal children during puberty. It occurs before skeletal maturity. Although there is still no cause for AIS, the natural history of AIS has been established in the literature very well. The aim of nonoperative treatment is mainly an attempt to prevent progression of the curve. Bracing and surgery have been used for large and or progressive curves currently. Many conservative treatments are available for adolescents with idiopathic scoliosis (AIS. Although there are numerous studies in literature that have tried to summarize the results of treatment, the evidence for their accepted use is still unclear. Many clinicians skeptical about the efficacy of conservative treatments. Because there is no consistency of both the inclusion criteria and the definitions of brace effectiveness. The definition of success or who should be included in the analysis have never been universally agreed upon. The Scoliosis Research Society established parameters for all future AIS bracing studies to be able to make comparison among studies more valid and reliable. These guidelines may standardize orthotic studies by recommending inclusion and assessment criteria and allow the promotion of the effectiveness of different braces and decrease the suspicion about their usefulness. Orthotic treatment in adolescent idiopathic scoliosis is used to control spinal curvatures while waiting for skeletal maturation.

    Pulmonary artery aneurysm (PAA) is an uncommon lesion, which may be associated with different etiologies including congenital cardiovascular diseases, systemic vasculitis, connective tissue diseases, infections, and trauma. Idiopathic PAA is sporadically diagnosed by exclusion of concomitant major pathology. We report a case of a 56-year-old female with an idiopathic pulmonary artery dilatation identified fortuitously by echocardiography and confirmed by contrast-enhanced computed tomography. Neither significant pulmonary valve dysfunction nor pulmonary hypertension and other cardiac abnormalities which might contribute to the PAA development were found. Here, we describe echocardiographic and computed tomography findings and review the literature on PAA management.

    Hypertrophic cardiomyopathy (HCM) is the most common monogenic heart disease with a frequency as high as 1 in 200. In many cases, HCM is caused by mutations in genes encoding the different components of the sarcomere apparatus. Hypertrophic cardiomyopathy is characterized by unexplained left ventricular hypertrophy, myofibrillar disarray, and myocardial fibrosis. The phenotypic expression is quite variable. Although most patients with HCM are asymptomatic, serious consequences are experienced in a subset of affected individuals who present initially with sudden cardiac death or progress to refractory heart failure. The Hypertrophic Cardiomyopathy Registry study is a National Heart, Lung, and Blood Institute-sponsored 2,750-patient, 44-site, international registry and natural history study designed to address limitations in extant evidence to improve prognostication in HCM (NCT01915615). In addition to the collection of standard demographic, clinical, and echocardiographic variables, patients will undergo state-of-the-art cardiac magnetic resonance for assessment of left ventricular mass and volumes as well as replacement scarring and interstitial fibrosis. In addition, genetic and biomarker analyses will be performed. The Hypertrophic Cardiomyopathy Registry has the potential to change the paradigm of risk stratification in HCM, using novel markers to identify those at higher risk.

    Spinal infections can occur in a variety of clinical situations. Their presentation ranges from the infant with diskitis who is unwilling to crawl or walk to the adult who develops an infection after a spinal procedure. The most common types of spinal infections are hematogenous bacterial or fungal infections, pediatric diskitis, epidural abscess, and postoperative infections. Prompt and accurate diagnosis of spinal infections, the cornerstone of treatment, requires a high index of suspicion in at-risk patients and the appropriate evaluation to identify the organism and determine the extent of infection. Neurologic function and spinal stability also should be carefully evaluated. The goals of therapy should include eradicating the infection, relieving pain, preserving or restoring neurologic function, improving nutrition, and maintaining spinal stability.

    Spinal involvement in human brucellosis is a common condition and a significant cause of morbidity and mortality, particularly in endemic areas, because it is often associated with therapeutic failure. Most chronic brucellosis cases are the result of inadequate treatment of the initial episode. Recognition of spinal brucellosis is challenging. Early diagnosis is important to ensure proper treatment and decrease morbidity and mortality. Radiologic evaluation has gained importance in diagnosis and treatment planning, including interventional procedures and monitoring of all spinal infections.

    2008-02-01

    The diagnosis of hypertrophic cardiomyopathy, an autosomal dominant chronic heart disease, can have significant implications, including increased risk of sudden death, exercise limitations, and risk of transmission to offspring. This study sought to describe the psychosocial factors associated with attending a specialty cardiac genetic clinic, and to determine whether these may be predictors of comorbid anxiety and depression in this population. Questionnaires were sent to 184 individuals attending the Royal Prince Alfred Hospital Hypertrophic Cardiomyopathy Clinic. Questionnaires were anonymous and comprised demographics, the Hospital Anxiety and Depression Scale, Patient Experience Scales, and Patient Satisfaction Scales. Completed questionnaires were returned by 109 participants (59.2% response rate), of which 76.9% had a diagnosis of hypertrophic cardiomyopathy, while 23.1% were at-risk relatives attending for clinical screening. Patient satisfaction scores were generally high to very high across all groups, though only 24% of HCM patients showed good adjustment to hypertrophic cardiomyopathy and 10% had low worry about hypertrophic cardiomyopathy scores. Within the disease group, logistic regression analysis adjusting for age, gender, and education revealed adjustment to hypertrophic cardiomyopathy and worry about hypertrophic cardiomyopathy scores to be significantly associated with anxiety, while adjustment scores and location of patient follow-up (i.e., Hypertrophic Cardiomyopathy clinic or another cardiologist) to be significantly associated with depression scores. HCM patients who attend specialized cardiac genetic clinics are better adjusted and worry less, than those who do not attend. An integrated approach, including a genetic counselor, is important in the management of HCM families.

  6. Periostin induces fibroblast proliferation and myofibroblast persistence in hypertrophic scarring.

    2015-02-01

    Hypertrophic scarring is characterized by the excessive development and persistence of myofibroblasts. These cells contract the surrounding extracellular matrix resulting in the increased tissue density characteristic of scar tissue. Periostin is a matricellular protein that is abnormally abundant in fibrotic dermis, however, its roles in hypertrophic scarring are largely unknown. In this report, we assessed the ability of matrix-associated periostin to promote the proliferation and myofibroblast differentiation of dermal fibroblasts isolated from the dermis of hypertrophic scars or healthy skin. Supplementation of a thin type-I collagen cell culture substrate with recombinant periostin induced a significant increase in the proliferation of hypertrophic scar fibroblasts but not normal dermal fibroblasts. Periostin induced significant increases in supermature focal adhesion formation, α smooth muscle actin levels and collagen contraction in fibroblasts cultured from hypertrophic scars under conditions of increased matrix tension in three-dimensional type-I collagen lattices. Inhibition of Rho-associated protein kinase activity significantly attenuated the effects of matrix-associated periostin on hypertrophic scar fibroblasts and myofibroblasts. Depletion of endogenous periostin expression in hypertrophic scar myofibroblasts resulted in a sustained decrease in α smooth muscle actin levels under conditions of reducing matrix tension, while matrix-associated periostin levels caused the cells to retain high levels of a smooth muscle actin under these conditions. These findings indicate that periostin promotes Rho-associated protein kinase-dependent proliferation and myofibroblast persistence of hypertrophic scar fibroblasts and implicate periostin as a potential therapeutic target to enhance the resolution of scars.

    Lichen planus is a chronic mucocutaneous T-cell-mediated disease, the cause of which remains unknown. The first case of lichen planus that transformed into squamous cell carcinoma was reported in 1903. The presented study concerns the case of a 62-year-old woman in whom twice malignant transformation of hypertrophic lichen planus in the dorsal part of the left foot developed. Several studies have pointed out the malignant transformation potential of lichen planus. Epidemiological studies from the last 20 years have revealed a malignant transformation rate of 0.27% per year, emphasizing the importance of the clinical follow-up of lichen planus patients.

    To describe 2 topographic facial pain conditions with the pain clearly localized in the eye (idiopathic ophthalmodynia) or in the nose (idiopathic rhinalgia), and to propose their distinction from persistent idiopathic facial pain. Persistent idiopathic facial pain, burning mouth syndrome, atypical odontalgia, and facial arthromyalgia are idiopathic facial pain syndromes that have been separated according to topographical criteria. Still, some other facial pain syndromes might have been veiled under the broad term of persistent idiopathic facial pain. Through a 10-year period we have studied all patients referred to our neurological clinic because of facial pain of unknown etiology that might deviate from all well-characterized facial pain syndromes. In a group of patients we have identified 2 consistent clinical pictures with pain precisely located either in the eye (n=11) or in the nose (n=7). Clinical features resembled those of other localized idiopathic facial syndromes, the key differences relying on the topographic distribution of the pain. Both idiopathic ophthalmodynia and idiopathic rhinalgia seem specific pain syndromes with a distinctive location, and may deserve a nosologic status just as other focal pain syndromes of the face. Whether all such focal syndromes are topographic variants of persistent idiopathic facial pain or independent disorders remains a controversial issue.

  14. Hypoxia inhibits hypertrophic differentiation and endochondral ossification in explanted tibiae.

    Directory of Open Access Journals (Sweden)

    Jeroen C H Leijten

    Full Text Available PURPOSE: Hypertrophic differentiation of growth plate chondrocytes induces angiogenesis which alleviates hypoxia normally present in cartilage. In the current study, we aim to determine whether alleviation of hypoxia is merely a downstream effect of hypertrophic differentiation as previously described or whether alleviation of hypoxia and consequent changes in oxygen tension mediated signaling events also plays an active role in regulating the hypertrophic differentiation process itself. MATERIALS AND METHODS: Fetal mouse tibiae (E17.5 explants were cultured up to 21 days under normoxic or hypoxic conditions (21% and 2.5% oxygen respectively. Tibiae were analyzed on growth kinetics, histology, gene expression and protein secretion. RESULTS: The oxygen level had a strong influence on the development of explanted fetal tibiae. Compared to hypoxia, normoxia increased the length of the tibiae, length of the hypertrophic zone, calcification of the cartilage and mRNA levels of hypertrophic differentiation-related genes e.g. MMP9, MMP13, RUNX2, COL10A1 and ALPL. Compared to normoxia, hypoxia increased the size of the cartilaginous epiphysis, length of the resting zone, calcification of the bone and mRNA levels of hyaline cartilage-related genes e.g. ACAN, COL2A1 and SOX9. Additionally, hypoxia enhanced the mRNA and protein expression of the secreted articular cartilage markers GREM1, FRZB and DKK1, which are able to inhibit hypertrophic differentiation. CONCLUSIONS: Collectively our data suggests that oxygen levels play an active role in the regulation of hypertrophic differentiation of hyaline chondrocytes. Normoxia stimulates hypertrophic differentiation evidenced by the expression of hypertrophic differentiation related genes. In contrast, hypoxia suppresses hypertrophic differentiation of chondrocytes, which might be at least partially explained by the induction of GREM1, FRZB and DKK1 expression.

    Cardiac hypertrophy is a common postmortem finding in owl monkeys. In most cases the animals do not exhibit clinical signs until the disease is advanced, making antemortem diagnosis of subclinical disease difficult and treatment unrewarding. We obtained echocardiograms, electrocardiograms, and thoracic radiographs from members of a colony of owl monkeys that previously was identified as showing a 40% incidence of gross myocardial hypertrophy at necropsy, to assess the usefulness of these modalities for antemortem diagnosis. No single modality was sufficiently sensitive and specific to detect all monkeys with cardiac hypertrophy. Electrocardiography was the least sensitive method for detecting owl monkeys with hypertrophic cardiomyopathy. Thoracic radiographs were more sensitive than was electrocardiography in this context but cannot detect animals with concentric hypertrophy without an enlarged cardiac silhouette. Echocardiography was the most sensitive method for identifying cardiac hypertrophy in owl monkeys. The most useful parameters suggestive of left ventricular hypertrophy in our owl monkeys were an increased average left ventricular wall thickness to chamber radius ratio and an increased calculated left ventricular myocardial mass. Parameters suggestive of dilative cardiomyopathy were an increased average left ventricular myocardial mass and a decreased average ratio of left ventricular free wall thickness to left ventricular chamber radius. When all 4 noninvasive diagnostic modalities (physical examination, echocardiography, electrocardiography, and thoracic radiography) were used concurrently, the probability of detecting hypertrophic cardiomyopathy in owl monkeys was increased greatly.

    F. De Leonardis

    2011-09-01

    Full Text Available Diffuse idiopathic skeletal hyperostosis (D.I.S.H. is a common disorder of unknown aetiology characterized by exuberant hyperostosis of the antero-lateral aspect of the spinal column, that sometimes leads to bone ankilosis, and by ossification of extra-spinal entheses. This condition is often associated with the metabolic derangement of type 2 diabetes. Primary hypertension, its cardiovascular aftereffects and lithiasis are also often present in these patients. D.I.S.H. has to be distinguished from osteoarthritis, althought they often coexist in the same patient. The mean difference lies in the anatomical target of the pathological process, that is represented by articular cartilage in osteoarthritis and by entheses in diffuse idiopathic skeletal hyperostosis. The enthesopathy leads to the ossification of the anterior longitudinal ligament of the spine and causes the formation of flowing osteophytes, while intervertebral disc space is quite preserved in early phases of the disease. Symptoms of spine involvement are not typical of the disease and consist of pain and stiffness, usually worsened by inaction and damp. It has also been described the ossification of posterior longitudinal ligament which can lead to medullary canal stenosis. Appendicular skeleton is symmetrically involved in early phases of the disease, the most distinctive affected sites being feet, olecranus and patella. Hip involvement is also frequent and may lead to severe disability and represents an important cause of invalidity. The purpose of the present review is to remark on aetiopathogenetic and clinical aspects of diffuse idiopathic skeletal hyperostosis.

  2. [Bracing in Adolescent Idiopathic Scoliosis].

    Science.gov (United States)

    Lo, Yi-Fang; Huang, Yu-Chu

    2017-04-01

    Scoliosis is a common medical problem, with an incidence of between 0.47% and 5.2% in the general population globally. Adolescent idiopathic scoliosis (AIS) accounts for nearly 80% of all scoliosis. Young people with AIS often experience negative social consequences in association with their condition. Without proper and timely treatment, the potential resulting disabilities range from trunk deformity, pain, and neurological complications to compromised cardiopulmonary function, all of which may cause lifelong suffering. Scoliosis may be treated either conservatively or surgically, based on the severity of the disease. Bracing is the most widely adopted method of conservative treatment. However, the main goal of bracing is to inhibit the progression of the spinal curvature rather than to cure scoliosis. The clinical effectiveness of bracing in Taiwan has often been underutilized as a result of financial or other factors such as the availability of the treatment. The purpose of the present review is to clarify the effectiveness of bracing for AIS by elucidating the pathophysiology of scoliosis and examining the recent clinical evidence. The importance of preventative care and the unique contribution of nursing care to treatment has to date been under-recognized. The positive support that nurses provide to the families of the patients during the early phases of treatment as well as to the patients themselves, including helping them exercise appropriately and wear the brace correctly, is an essential component of effective treatment. Learning how to work with and to adapt to the brace being part of the body is an important part of the treatment as well as a way to avoid pain. Nurses are in an ideal position to facilitate this learning process and, overall, to provide health education.

    Hypertrophic scarring after burns remains a major problem and is considered to be "common". Pressure garments are commonly used as treatment even though there is little sound data that they reduce the prevalence or magnitude of the scarring. In 1999 we began a study of the efficacy of pressure garments on forearm burns. After studying 30 patients, mainly white adults, we found no hypertrophic scar in either those treated with pressure or without. This prompted us to review the literature on the prevalence of hypertrophic scarring after burns and found only four articles with a relatively small number of patients and only three geographical locations. It became clear that the prevalence of hypertrophic scarring is really unknown. We then did a retrospective study of 110 burn survivors and counted all hypertrophic scars of all sizes and locations in all races and found the prevalence hypertrophic scarring to be 67% which conflicts with the published reports and our prospective study and suggests that further research is necessary. We concluded that a worldwide, prospective survey is necessary to establish the prevalence of hypertrophic scarring after burns. In this article we are calling for and offering to organize this survey.

    Genetic testing for hypertrophic cardiomyopathy has been commercially available for almost a decade; however, low mutation detection rate and cost have hindered uptake. This study sought to identify clinical variables that can predict probands with hypertrophic cardiomyopathy in whom a pathogenic mutation will be identified. Probands attending specialized cardiac genetic clinics across Australia over a 10-year period (2002-2011), who met clinical diagnostic criteria for hypertrophic cardiomyopathy and who underwent genetic testing for hypertrophic cardiomyopathy were included. Clinical, family history, and genotype information were collected. A total of 265 unrelated individuals with hypertrophic cardiomyopathy were included, with 138 (52%) having at least one mutation identified. The mutation detection rate was significantly higher in the probands with hypertrophic cardiomyopathy with an established family history of disease (72 vs. 29%, P < 0.0001), and a positive family history of sudden cardiac death further increased the detection rate (89 vs. 59%, P < 0.0001). Multivariate analysis identified female gender, increased left-ventricular wall thickness, family history of hypertrophic cardiomyopathy, and family history of sudden cardiac death as being associated with greatest chance of identifying a gene mutation. Multiple mutation carriers (n = 16, 6%) were more likely to have suffered an out-of-hospital cardiac arrest or sudden cardiac death (31 vs. 7%, P = 0.012). Family history is a key clinical predictor of a positive genetic diagnosis and has direct clinical relevance, particularly in the pretest genetic counseling setting.

    Posterolateral hypertrophic cardiomyopathy (HCM) is a rare variant of HCM. Segmental HCM is seen in 12% of cases of HCM. Among the patterns of segmental HCM, posterolateral HCM is the least common type. Our case of an 18-year old male documents this unusual type of cardiomyopathy. In this form of HCM, left ventricular thickness and the extent of hypertrophy might be underestimated by 2-dimensional echocardiography. This case illustrates the echocardiographic and pathologic features of posterolateral HCM.

    Hypertrophic cardiomyopathy (HCM) is the most frequent genetic cardiac disease that causes sudden death in young people, with an incidence of 1:500 adults. The routinely used criteria for worst prognosis have limited sensitivity and specificity. Thus, the estimated risk of evolving to dilated cardiomyopathy or sudden death is somewhat inaccurate, leading to management uncertainty of HCM patients. Therefore, an accurate noninvasive method for the diagnosis of HCM with prognostic value is of great importance. In the last years, Cardiovascular Magnetic Resonance (CMR) emerged not only as a diagnostic tool, but also as a study with prognostic values, by characterizing myocardial fibrosis with great accuracy in HCM patients. Additionally, CMR identifies the types of hypertrophy, analyses the ventricular function, estimates the intraventricular gradient and allows the determination of differential diagnosis. Moreover, CMR can uniquely access myocardial fibrosis in HCM. (author)

  14. Hypertrophic Obesity and Subcutaneous Adipose Tissue Dysfunction

    Directory of Open Access Journals (Sweden)

    Anna Meiliana

    2014-08-01

    Full Text Available BACKGROUND: Over the past 50 years, scientists have recognized that not all adipose tissue is alike, and that health risk is associated with the location as well as the amount of body fat. Different depots are sufficiently distinct with respect to fatty-acid storage and release as to probably play unique roles in human physiology. Whether fat redistribution causes metabolic disease or whether it is a marker of underlying processes that are primarily responsible is an open question. CONTENT: The limited expandability of the subcutaneous adipose tissue leads to inappropriate adipose cell expansion (hypertrophic obesity with local inflammation and a dysregulated and insulin-resistant adipose tissue. The inability to store excess fat in the subcutaneous adipose tissue is a likely key mechanism for promoting ectopic fat accumulation in tissues and areas where fat can be stored, including the intra-abdominal and visceral areas, in the liver, epi/pericardial area, around vessels, in the myocardium, and in the skeletal muscles. Many studies have implicated ectopic fat accumulation and the associated lipotoxicity as the major determinant of the metabolic complications of obesity driving systemic insulin resistance, inflammation, hepatic glucose production, and dyslipidemia. SUMMARY: In summary, hypertrophic obesity is due to an impaired ability to recruit and differentiate available adipose precursor cells in the subcutaneous adipose tissue. Thus, the subcutaneous adipose tissue may be particular in its limited ability in certain individuals to undergo adipogenesis during weight increase. Inability to promote subcutaneous adipogenesis under periods of affluence would favor lipid overlow and ectopic fat accumulation with negative metabolic consequences. KEYWORDS: obesity, adipogenesis, subcutaneous adipose tissue, visceral adipose tissue, adipocyte dysfunction.

  1. A major QTL controls susceptibility to spinal curvature in the curveback guppy

    Directory of Open Access Journals (Sweden)

    Dreyer Christine

    2011-01-01

    Full Text Available Abstract Background Understanding the genetic basis of heritable spinal curvature would benefit medicine and aquaculture. Heritable spinal curvature among otherwise healthy children (i.e. Idiopathic Scoliosis and Scheuermann kyphosis accounts for more than 80% of all spinal curvatures and imposes a substantial healthcare cost through bracing, hospitalizations, surgery, and chronic back pain. In aquaculture, the prevalence of heritable spinal curvature can reach as high as 80% of a stock, and thus imposes a substantial cost through production losses. The genetic basis of heritable spinal curvature is unknown and so the objective of this work is to identify quantitative trait loci (QTL affecting heritable spinal curvature in the curveback guppy. Prior work with curveback has demonstrated phenotypic parallels to human idiopathic-type scoliosis, suggesting shared biological pathways for the deformity. Results A major effect QTL that acts in a recessive manner and accounts for curve susceptibility was detected in an initial mapping cross on LG 14. In a second cross, we confirmed this susceptibility locus and fine mapped it to a 5 cM region that explains 82.6% of the total phenotypic variance. Conclusions We identify a major QTL that controls susceptibility to curvature. This locus contains over 100 genes, including MTNR1B, a candidate gene for human idiopathic scoliosis. The identification of genes associated with heritable spinal curvature in the curveback guppy has the potential to elucidate the biological basis of spinal curvature among humans and economically important teleosts.

    A case of hypertrophic obstructive cardiomyopathy in a patient with Turner syndrome is reported. The most frequently associated cardiac anomalies are coarctation of the aorta and bicuspid aortic valve. Hypertrophic cardiomyopathy has never been reported in this syndrome but is frequent in Noonan syndrome. In these two conditions the phenotype may be indistinguishable but the cariotype is different: normal in Noonan and 45X in Turner syndrome. Our patient had the typical somatic features, and the cariotype was 45X in all examined cells. A familial form of hypertrophic cardiomyopathy was excluded by the normal clinical examination of other members of the family. The presence of hypertrophic cardiomyopathy also in Turner syndrome and the recent localization on the long arm of the chromosome 12 of the gene for Noonan syndrome might postulate a common pathogenesis of the two syndromes.

    Nemaline myopathy is a congenital nonprogressive skeletal muscle disorder with a characteristic rod body formation in the skeletal muscle fibers. Cardiac involvement in nemaline myopathy is rare, although both dilated and hypertrophic cardiomyopathy have been reported. We describe an infant diagnosed with hypertrophic cardiomyopathy and hypotonia on the first day of life. Muscle biopsy confirmed nemaline myopathy at 3 weeks of age. The diagnosis of nemaline myopathy precluded consideration of heart transplantation, thus shifting the focus to comfort care. This is the earliest presentation of hypertrophic cardiomyopathy reported in the literature in the setting of nemaline myopathy. The approach to determining an etiology for hypertrophic cardiomyopathy in an infant is reviewed. © 2011 Wiley Periodicals, Inc.

    Schubeus, P.; Schoerner, W.; Hosten, N.; Felix, R. (Free University of Berlin, University Clinic Rudolf Virchow, Charlottenburg (Germany). Department of Radiology)

    MRI examinations of 30 patients with idiopathic syringomyelia and 10 patients with cavities associated with an intramedullary neoplasm were evaluated with respect to typical MRI features in both groups. Al tumor-associated cases resembled the idiopathic syringomyelias in some portions of the cavity. At the tumor site, however, tumor-associated cases demonstrated typical findings; the cavities showed abrupt changes of diameter (10/10) and position (8/10) and the surrounding spinal cord demonstrated an uneven thickness (10/10), an increased signal intensity on T2-weighted images (10/10) and pathological contrast enhancement (7/7). Displacement of cerebellar tonsils below the level of the foramen magnum (921/30) and enlargement of the spinal canal (97/29) were characteristic features of idiopathic cases. In conclusion, MRI provides valuable criteria to differentiate between idiopathic and tumor-associated cavities. (author). 19 refs.; 4 figs.; 1 tab.

  13. Large spinal intraosseous arteriovenous fistula: case report.

    Imajo, Yasuaki; Kanchiku, Tsukasa; Yoshida, Yuichiro; Nishida, Norihiro; Taguchi, Toshihiko

    2015-04-01

    Here the authors report the case of a fresh vertebral body fracture with a large spinal intraosseous arteriovenous fistula (AVF). A 74-year-old woman started to experience low-back pain following a rear-end car collision. Plain radiography showed diffuse idiopathic skeletal hyperostosis (DISH). Sagittal CT sections revealed a transverse fracture of the L-4 vertebral body with a bone defect. Sagittal fat-suppressed T2-weighted MRI revealed a flow void in the fractured vertebra. Spinal angiography revealed an intraosseous AVF with a feeder from the right L-4 segmental artery. A fresh fracture of the L-4 vertebral body with a spinal intraosseous AVF was diagnosed. Observation of a flow void in the vertebral body on fat-suppressed T2-weighted MRI was important for the diagnosis of the spinal intraosseous AVF. Because conservative treatment was ineffective, surgery was undertaken. The day before surgery, embolization through the right L-4 segmental artery was performed using 2 coils to achieve AVF closure. Posterolateral fusion with instrumentation at the T12-S2 vertebral levels was performed without L-4 vertebroplasty. The spinal intraosseous AVF had disappeared after 4 months. At 24 months after surgery, the bone defect was completely replaced by bone and the patient experienced no limitations in daily activities. Given their experience with the present case, the authors believe that performing vertebroplasty or anterior reconstruction may not be necessary in treating spinal intraosseous AVF.

    2013-01-01

    Full Text Available Growth is a complex process and the basic characteristic of child- hood growth monitoring provides insight into the physiological and pathological events in the body. Statistically, the short stature means departure from the values of height for age and sex (in a particular environment, which is below -2 standard deviation score, or less than -2 standard deviation, i.e. below the third percentile. Advances in molecular genetics have contributed to the improvement of diagnostics in endocrinology. Analysis of patients’ genotypes should not be performed before taking a classical history, detailed clinical examination and appropriate tests. In patients with idiopathic short stature specific causes are excluded, such as growth hormone deficiency, Turner syndrome, short stature due to low birth weight, intrauterine growth retardation, small for gestational age, dysmorphology syndromes and chronic childhood diseases. The exclusion of abovementioned conditions leaves a large number of children with short stature whose etiology includes patients with genetic short stature or familial short stature and those who are low in relation to genetic potential, and who could also have some unrecognized endocrine defect. Idiopathic short stature represents a short stature of unknown cause of heterogeneous etiology, and is characterized by a normal response of growth hormone during stimulation tests (>10 ng/ml or 20 mJ/l, without other disorders, of normal body mass and length at birth. In idiopathic short stature standard deviation score rates <-2.25 (-2 to -3 or <1.2 percentile. These are also criteria for the initiation of growth hormone therapy. In children with short stature there is also the presence of psychological and social suffering. Goals of treatment with growth hormone involve achieving normal height and normal growth rate during childhood.

    Idiopathic granulomatous orchitis is a rare inflammatory process of the testis of unknown etiology. It is characterized by presence of non-specific granulomatous inflammation and admixed multinucleated giant cells. It usually presents as a testicular mass which is highly suspicious of malignancy. Histologically, there is extensive destruction of seminiferous tubules with tubular or interstitial pattern of granulomatous inflammation and prominent collagen fibrosis. Trauma and possible auto-antibodies against sperms have been postulated to be the underlying mechanism. Differential diagnoses include intratubular germ-cell neoplasia, malignant lymphomas, and malakoplakia. Orchiectomy is currently the most appropriate therapy for this condition.

    Transverse myelitis is a focal inflammatory disorder of the spinal cord which may arise due to different etiologies. Transverse myelitis may be idiopathic or related/secondary to other diseases including infections, connective tissue disorders and other autoimmune diseases. It may be also associated with optic neuritis (neuromyelitis optica), which may precede transverse myelitis. In this manuscript we review the pathophysiology of different types of transverse myelitis and neuromyelitis optica and discuss diagnostic criteria for idiopathic transverse myelitis and risk of development of multiple sclerosis after an episode of transverse myelitis. We also discuss treatment options including corticosteroids, immunosuppressives and monoclonal antibodies, plasma exchange and intravenous immunoglobulins. PMID:22379456

    Idiopathic pulmonary fibrosis is a fibrosing interstitial pneumonia associated with the radiological and/or histological pattern of usual interstitial pneumonia. Its aetiology is unknown, but probably comprises the action of endogenous and exogenous micro-environmental factors in subjects with genetic predisposition. Its diagnosis is based on the presence of characteristic findings of high-resolution computed tomography scans and pulmonary biopsies in absence of interstitial lung diseases of other aetiologies. Its clinical evolution is variable, although the mean survival rate is 2-5 years as of its clinical presentation. Patients with idiopathic pulmonary fibrosis may present complications and comorbidities which modify the disease's clinical course and prognosis. In the mild-moderate disease, the treatment consists of the administration of anti-fibrotic drugs. In severe disease, the best therapeutic option is pulmonary transplantation. In this paper we review the diagnostic and therapeutic aspects of the disease. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    1997-12-01

    The usefulness of {sup 123}I-BMIPP myocardial SPECT in discriminating hypertrophic cardiomyopathy (46 patients), hypertrophic cardiomyopathy with hypertension (23 patients), and hypertensive hypertrophic heart (20 patients) was studied. SPECT image was divided into 17 domains, and dimension of decreased accumulation was decided visually at each domain as four classes called defect score (DS). Summation of DS (TDS) of each group was used to compare frequency and dimension of decreased accumulation, and characteristic of each site. Frequency of decreased accumulation and TDS in hypertrophic cardiomyopathy were similar in dimension with those in hypertrophic cardiomyopathy with hypertension, and those data in hypertensive hypertrophic heart were lower than those in above-mentioned 2 groups. In the cases of hypertrophic cardiomyopathy and hypertrophic cardiomyopathy with hypertension, decreased accumulation site was similar and was anterior wall-septum junction, septum-posterior wall junction and apex of heart. In the case of hypertensive hypertrophic heart, decreased accumulation site was only the posterior wall. Frequency, dimension and site of decreased accumulation in hypertrophic cardiomyopathy were different from those in hypertensive hypertrophic heart, and BMIPP was thought to be useful in discriminating these diseases.

    To describe the magnetic resonance (MR) imaging findings of hypertrophic olivary degeneration (HOD) MR images of seven patients with HOD were retrospectively reviewed. Two were women and five were men, and they were aged between 48 and 65 (mean 58) years. Imaging examinations were performed with a 1.5-T unit, and the findings were used to evaluate the size and signal intensity of olivary lesions. The time interval from hemorrhagic ictus to MR imaging was between two and 30 months. Follow-up examinations were performed in two patients. All four patients with hemorrhages involving the central tegmental tract in the pons or midbrain showed ipsilateral HOD. Among these four, bilateral HOD was seen in one patient with hemorrhage involving the bilateral central tegmental tract, and in another with tegmental hemorrhage extending to the ipsilateral superior cerebellar peduncle. One patient with cerebellar hemorrhage involving the dentate nucleus had contralateral HOD. Two patients with multiple hemorrhages involving both the pons and cerebellum showed bilateral HOD. Axial MR images showed mild enlargement of the involved olivary mucleus, with high signal intensity on both proton density and T2 weighted images. There was no apparent enhancement on postcontrast T1-weighted images. MR imaging can clearly distinguish secondary olivary degeneration from underlying pathology involving the central tegmental tract in the pons or midbrain and cerebellum. These olivary abnormalities should not, however, be mistaken for primary medullary lesions.

    Idiopathic erythermalgia during early childhood and adolescence is characterized by red, congested, burning pain of the lower extremities provoked by exercise or exposure to warmth. The clinical symptoms of idiopathic erythermalgia in a young woman and her mother are described. Histopathologic and immunofluorescence findings in biopsy specimens of affected areas of skin were consistent with a nonspecific inflammatory process. The condition was completely refractory to any treatment. Even the long-lasting relief of pain with one low dose of aspirin, which is a prerequisite for the diagnosis of thrombocytemic erythromelalgia, was lacking. Idiopathic erythermalgia appears to be a separate clinical entity and congenital disorder.

    Idiopathic scoliosis is a spinal deformity affecting approximately 3% of otherwise healthy children or adolescents. The etiology is still largely unknown but has an important genetic component. Genome-wide association studies have identified a number of common genetic variants that are significantly associated with idiopathic scoliosis in Asian and Caucasian populations, rs11190870 close to the LBX1 gene being the most replicated finding. The aim of the present study was to investigate the genetics of idiopathic scoliosis in a Scandinavian cohort by performing a candidate gene study of four variants previously shown to be associated with idiopathic scoliosis and exome sequencing of idiopathic scoliosis patients with a severe phenotype to identify possible novel scoliosis risk variants. This was a case control study. A total of 1,739 patients with idiopathic scoliosis and 1,812 controls were included. The outcome measure was idiopathic scoliosis. The variants rs10510181, rs11190870, rs12946942, and rs6570507 were genotyped in 1,739 patients with idiopathic scoliosis and 1,812 controls. Exome sequencing was performed on pooled samples from 100 surgically treated idiopathic scoliosis patients. Novel or rare missense, nonsense, or splice site variants were selected for individual genotyping in the 1,739 cases and 1,812 controls. In addition, the 5'UTR, noncoding exon and promoter regions of LBX1, not covered by exome sequencing, were Sanger sequenced in the 100 pooled samples. Of the four candidate genes, an intergenic variant, rs11190870, downstream of the LBX1 gene, showed a highly significant association to idiopathic scoliosis in 1,739 cases and 1,812 controls (p=7.0×10(-18)). We identified 20 novel variants by exome sequencing after filtration and an initial genotyping validation. However, we could not verify any association to idiopathic scoliosis in the large cohort of 1,739 cases and 1,812 controls. We did not find any variants in the 5'UTR, noncoding exon and

    The purpose of the present study was to evaluate the potential advantages of transesophageal echocardiography (TEE) in comparison with transthoracic echocardiography (TTE) in selected patients with hypertrophic cardiomyopathy. Ten patients with previously established or suspected diagnosis of hypertrophic cardiomyopathy were examined by TEE to solve specific clinical questions. TEE was well tolerated by all patients; no arrhythmias were seen during the procedure. The comparison of TTE and TEE showed the following: Advantages of TTE--better assessment of the left ventricle, myocardial thickness measurements available in all regions and sufficient for the diagnosis of hypertrophic cardiomyopathy in nine out of 10 patients; advantages of TEE--precise assessment of mitral valve morphology and regurgitant jets, detailed evaluation of systolic anterior motion, and subaortic membrane (not seen by TTE) recognized in one patient. Clinically, in three patients TEE influenced the management (mitral leaflet perforation, subaortic membrane, and residual mitral regurgitation after valvuloplasty). Thus TEE enables more precise diagnosis in some patients with hypertrophic cardiomyopathy and has the potential to influence their surgical management. However, for medical treatment of hypertrophic cardiomyopathy, TTE is sufficient.

    Full Text Available Hypertrophic scar is a complication of wound healing and has a high recurrence rate which can lead to significant abnormity in aesthetics and functions. To date, no ideal treatment method has been established. Meanwhile, the underlying mechanism of hypertrophic scarring has not been clearly defined. Although a large amount of scientific research has been reported on the use of medicinal plants as a natural source of treatment for hypertrophic scarring, it is currently scattered across a wide range of publications. Therefore, a systematic summary and knowledge for future prospects are necessary to facilitate further medicinal plant research for their potential use as antihypertrophic scar agents. A bibliographic investigation was accomplished by focusing on medicinal plants which have been scientifically tested in vitro and/or in vivo and proved as potential agents for the treatment of hypertrophic scars. Although the chemical components and mechanisms of action of medicinal plants with antihypertrophic scarring potential have been investigated, many others remain unknown. More investigations and clinical trials are necessary to make use of these medical plants reasonably and phytotherapy is a promising therapeutic approach against hypertrophic scars.

    Full Text Available Abstract Originally described by Brock and Teare, today hypertrophic cardiomyopathy is clinically defined as left (or right ventricular hypertrophy without a known cardiac or systemic cause, such as systemic hypertension, Fabry's disease or aortic stenosis. Also appreciated today is the enormous genotypic and phenotypic heterogeneity of this disease with more than 300 mutations over more than 24 genes, encoding various sarcomeric, mitochondrial and calcium-handling proteins, all as genetic causes for hypertrophic cardiomyopathy. Phenotypically, the disease can vary from negligible to extreme hypertrophy, affecting either the left and/or right ventricle in an apical, midventricular or subaortic location. Left ventricular false tendons are thin, fibrous or fibromuscular structures that traverse the left ventricular cavity. Recently, a case report was presented where it was shown that such a false tendon, originating from a subaortic location, was responsible for striking ST-segment elevation on the surface electrocardiogram. In this case report, a case is presented where such a subaortic tendon led to the classic echocardiographic appearance of hypertrophic cardiomyopathy, thus in the assessment of hypertrophic cardiomyopathy, this entity needs to be excluded in order to prevent a false positive diagnosis of hypertrophic cardiomyopathy.

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    The new classification of juvenile idiopathic arthritis (JIA) is described in this review. Clinical characteristics divide JIA in to subtypes: systemic, oligoarticular (persistent and extended type), RF-positive and--negative polyarticular, enthesitis-related arthritis and psoriatic arthritis. In addition to the clinical characteristics, genetic and biochemical differences suggest that JIA could be regarded as a general term covering various diseases. Complications described are uveitis, temporomandibular joint affection and growth disturbances. The therapeutic strategy should be planned individually according to age, subtype and disease activity and carried out as teamwork with several specialties. Drugs showing significant effectiveness in controlled studies are primarily methotrexate and sulphasalazine. An immunomodulating agent, etanercept, a soluble TNF alpha-receptor fusion protein, has shown a promising effect in severe polyarticular JIA refractory to methotrexate treatment.

    Idiopathic short stature (ISS) is a term used to describe the status of children with short stature that cannot be attributed to a specific cause. Many children diagnosed as having ISS have partial GH insensitivity, which can result from disturbances at various points of the GH-IGF-I axis. Several clinical studies on spontaneous growth in ISS showed that adult height was almost in the range of target height. GH treatment led to adult height not significantly higher than the pretreatment predicted adult height in most reports. No metabolic side effects have been observed, even when the dose was higher than in GH deficiency. Manipulation of puberty with gonadotrophin releasing hormone analogues reported by a few authors in a small number of children has shown conflicting results. Long-term psychological benefits of GH therapy for short normal children have not been demonstrated to date.

    Our aim was to clarify the correlation of attention deficit hyperactivity disorder (ADHD) with epilepsy and behavior problems. This was a cross-sectional study. Sixty children with idiopathic epilepsy were interviewed using the MTA-SNAP IV Teacher and Parent Rating Scale, Vineland Adaptive Behavior Scales and Conners' Rating Scales. We used the chi-square test to analyze the correlation of epilepsy variables in patients with and without ADHD with a significance level of 0.05. Eight patients had ADHD symptoms (13%), seven had the inattentive ADHD subtype and only three had behavioral problems. When epileptic patients with and without ADHD symptoms were compared we found no significant difference in regard to epilepsy variables. All patients were controlled and 43% were either without AED or undergoing withdrawal. Our study revealed a low comorbidity of ADHD symptoms and epilepsy due to low interference of seizures and drug treatment on the comorbid condition.

    Purpose Orbicularis weakness is commonly associated with seventh nerve palsy or neuromuscular and myopathic conditions such as myotonic dystrophy and myasethenia gravis. We report four cases of idiopathic isolated orbicularis weakness. Methods All four cases were female and the presenting symptoms of ocular irritation and epiphora had been present for over 7 years in three patients. All patients had lagophthalmos and three had ectropion. Three patients underwent full investigations which excluded known causes of orbicularis weakness. Two patients underwent oribularis oculi muscle biopsy and histological confirmation of orbicularis atrophy. Results All patients underwent surgery to specifically address the orbicularis weakness with satisfactory outcomes and alleviation of symptoms in all cases. Isolated orbicularis weakness may be a relatively common entity that is frequently overlooked. Conclusion Early recognition of this condition may lead to better management and prevent patients undergoing unnecessary surgical procedures. PMID:22322997

    Full Text Available Idiopathic thrombocytopenic purpura (ITP is defined as a hematologic disorder, characterized by isolated thrombocytopenia without a clinically apparent cause. The major causes of accelerated platelet consumption include immune thrombocytopenia, decreased bone marrow production, and increased splenic sequestration. The clinical presentation may be acute with severe bleeding, or insidious with slow development with mild or no symptoms. The initial laboratory tests useful at the first visit to predict future diagnosis were erythrocyte count, leukocyte count, anti-glycoprotein IIb/IIIa antibodies, reticulated platelets, plasma thrombopoietin level. Treatment should be restricted to those patients with moderate or severe thrombocytopenia who are bleeding or at risk of bleeding. We present a case report on ITP with clinical presentation, diagnosis and management.

    Full Text Available Juvenile Idiopathic Arthritis (JIA is the most chronic musculoskeletal disease of pediatric population. The chronic course of disease has a great impact on oral health. Temporomandibular joint is involved in JIA causing limited mouth opening with progressive open bite, retrognathia, microgenia and bird like appearance. Joints of upper and lower extremities are also involved. Effect on upper limb function leads to difficulty with fine motor movements required for brushing and flossing. This increases incidence of caries and periodontal disease in children. The cause of JIA is still poorly understood and none of the available drugs for JIA can cure the disease. However, prognosis has improved as a result of progress in disease classification and management. The dental practitioner should be familiar with the symptoms and oral manifestations of JIA to help manage as multidisciplinary management is essential.

    Idiopathic pulmonary fibrosis (IPF) is the most common of the idiopathic interstitial pneumonias. Despite multiple recent clinical trials, there is no strong evidence supporting a survival advantage for any agent in the management of patients with IPF. The limited effectiveness of current treatment regimes has led to a search for novel therapies including antifibrotic strategies. This article reviews the evidence supporting the treatments currently used in the management of IPF.

  7. Adolescent idiopathic scoliosis: Indications and efficacy of nonoperative treatment

    Directory of Open Access Journals (Sweden)

    Federico Canavese

    2011-01-01

    Full Text Available The strategy for the treatment of idiopathic scoliosis depends essentially upon the magnitude and pattern of the deformity, and its potential for progression. Treatment options include observation, bracing and/or surgery. During the past decade, several studies have demonstrated that the natural history of adolescent idiopathic scoliosis can be positively affected by nonoperative treatment, especially bracing. Other forms of conservative treatment, such as chiropractic or osteopathic manipulation, acupuncture, exercise or other manual treatments, or diet and nutrition, have not yet been proven to be effective in controlling spinal deformity progression, and those with a natural history that is favorable at the completion of growth. Observation is appropriate treatment for small curves, curves that are at low risk of progression, and those with a natural history that is favorable at the completion of growth. Indications for brace treatment are a growing child presenting with a curve of 25°-40° or a curve less than 25° with documented progression. Curves of 20°-25° in patients with pronounced skeletal immaturity should also be treated. The purpose of this review is to provide information about conservative treatment of adolescent idiopathic scoliosis. Indications for conservative treatment, hours daily wear and complications of brace treatment as well as brace types are discussed.

    Full Text Available Juvenile idiopathic arthritis is the most common autoimmune systemic disease of the connective tissue affecting individuals in the developmental age. Radiography, which was described in the first part of this publication, is the standard modality in the assessment of this condition. Ultrasound and magnetic resonance imaging enable early detection of the disease which affects soft tissues, as well as bones. Ultrasound assessment involves: joint cavities, tendon sheaths and bursae for the presence of synovitis, intraand extraarticular fat tissue to visualize signs of inflammation, hyaline cartilage, cartilaginous epiphysis and subchondral bone to detect cysts and erosions, and ligaments, tendons and their entheses for signs of enthesopathies and tendinopathies. Magnetic resonance imaging is indicated in children with juvenile idiopathic arthritis for assessment of inflammation in peripheral joints, tendon sheaths and bursae, bone marrow involvement and identification of inflammatory lesions in whole-body MRI, particularly when the clinical picture is unclear. Also, MRI of the spine and spinal cord is used in order to diagnose synovial joint inflammation, bone marrow edema and spondylodiscitis as well as to assess their activity, location, and complications (spinal canal stenosis, subluxation, e.g. in the atlantoaxial region. This article discusses typical pathological changes seen on ultrasound and magnetic resonance imaging. The role of these two methods for disease monitoring, its identification in the pre-clinical stage and establishing its remission are also highlighted.

Ultrasound assessment involves: joint cavities, tendon sheaths and bursae for the presence of synovitis, intraand extraarticular fat tissue to visualize signs of inflammation, hyaline cartilage, cartilaginous epiphysis and subchondral bone to detect cysts and erosions, and ligaments, tendons and their entheses for signs of enthesopathies and tendinopathies. Magnetic resonance imaging is indicated in children with juvenile idiopathic arthritis for assessment of inflammation in peripheral joints, tendon sheaths and bursae, bone marrow involvement and identification of inflammatory lesions in whole-body MRI, particularly when the clinical picture is unclear. Also, MRI of the spine and spinal cord is used in order to diagnose synovial joint inflammation, bone marrow edema and spondylodiscitis as well as to assess their activity, location, and complications (spinal canal stenosis, subluxation, e.g. in the atlantoaxial region). This article discusses typical pathological changes seen on ultrasound and magnetic resonance imaging. The role of these two methods for disease monitoring, its identification in the pre-clinical stage and establishing its remission are also highlighted. PMID:27679727

    Objective To develop a simplified Chinese version of spinal appearance questionnaire (SAQ) and assess its reliability and validity among patients with adolescent idiopathic scoliosis ( AIS). Methods The SAQ was translated and cross-culturally adapted into simplified Chinese according the international guideline. A total of 95 AIS patients were recruited to finish the simplified Chinese SAQ and SRS-22. In order to assess the test-retest reliability, 50 AIS patients were randomly selected to re-complete the SAQ at a time interval of 7 d. Internal consistency coefficient (ICC) was calculated and the Bland-Altman plot was made. Convergent validity was assessed by Pearson correlation analysis between the simplified Chinese SAQ with the simplified Chinese SRS-22 appearance domain, and discriminant validity by analyzing the relationship between simplified Chinese SAQ scores and the severity of deformity and different scheduled treatments. Results Internal consistency for the SAQ was satisfactory with intra-domain correlation coefficients ranging 0.521-0.792 (P < 0.01). The test-retest reliability for the SAQ was excellent with intra-class correlation coefficient being 0. 965 and good Bland-Altman agreement. Convergent validity test demonstrated a moderate correlation between the overall SAQ and SRS-22 appearance domain with r = - 0. 326 (P < 0.01). Correlation between the overall SAQ and the major Cobb' s angle was significant with r = 0. 779 (P < 0.01). Discriminant validity was confirmed by significant differences of SAQ total scores among the 3 subgroups categorized by the major Cobb's angle (P<0.001) and among patients who required exercise, bracing, or surgery (P<0.01). Conclusion Our simplified Chinese SAQ has satisfactory reliability and validity in evaluating spinal deformity appearance in Chinese AIS.%目的 建立简体中文版脊柱外观问卷(spinal appearance questionnaire,SAQ)并测验其用于评价青少年特发性脊柱侧凸患者

    Hypertrophic scars (HTSs) occur in 30 to 72% patients after thermal injury. Risk factors include skin color, female sex, young age, burn site, and burn severity. Recent correlations between genetic variations and clinical conditions suggest that single-nucleotide polymorphisms (SNPs) may be associated with HTS formation. The authors hypothesized that an SNP in the p27 gene (rs36228499) previously associated with decreased restenosis after coronary stenting would be associated with lower Vancouver Scar Scale (VSS) measurements and decreased itching. Patient and injury characteristics were collected from adults with thermal burns. VSS scores were calculated at 4 to 9 months after injury. Genotyping was performed using real-time polymerase chain reaction. Logistic regression was used to determine risk factors for HTS as measured by a VSS score >7. Three hundred subjects had a median age of 39 years (range, 18-91); 69% were male and median burn size was 7% TBSA (range, 0.25-80). Consistent with literature, the p27 variant SNP had an allele frequency of 40%, but was not associated with reduced HTS formation or lower itch scores in any genetic model. HTS formation was associated with American Indian/Alaskan Native race (odds ratio [OR], 12.2; P = .02), facial burns (OR, 9.4; P = .04), and burn size ≥20% TBSA (OR, 1.99; P = .03). Although the p27 SNP may protect against vascular fibroproliferation, the effect cannot be generalized to cutaneous scars. This study suggests that American Indian/Alaskan Native race, facial burns, and higher %TBSA are independent risk factors for HTS. The American Indian/Alaskan Native association suggests that there are potentially yet-to-be-identified genetic variants.

    Twenty-seven consecutive patients with adolescent idiopathic scoliosis underwent posterior spinal fusion with pediatric Texas Scottish Rite Hospital instrumentation. Coralline hydroxyapatite (Interpore, Irvine, Calif) was mixed with limited autograft from posterior iliac crest (an approximate 70/30 ratio of coralline hydroxyapatite to autograft). Patient evaluation was based on clinical and radiographic findings. On initial radiographic evaluation, a "snowstorm" appearance consistent with the exoskeleton of the coralline hydroxyapatite was observed. After two years, the fusion mass had a "marble-like" appearance with distinct decreased visibility of the disk spaces in the fusion mass. This latter stage of "marbilization correlated with solid fusion clinically. All patients achieved solid fusion at an average follow-up of 27 months. Coralline hydroxyapatite is safe, biocompatible, and effective in augmenting autogenous bone graft in the treatment of idiopathic adolescent scoliosis with posterior spinal fusion. In addition to decreased donor site morbidity, this may be invaluable in cases where there is insufficient autograft available.

    To determine the risk of noncardiac surgery in patients with hypertrophic cardiomyopathy.Methods We reviewed the medical records of all patients who were diagnosed as hypertrophic cardiomyopathy at Peking Union Medical College Hospital from January 1998 to August 2006 and identified 24 patients who subsequently underwent noncardiac surgery.Results There were no intraoperative cardiac events. Postoperative cardiac events were identified in 3 patients including 1 death due to acute myocardial infarction and 2 episodes of transient hypotension.Conclusions The risk of anesthesia and noncardiac surgery is low in patients with hypertrophic cardiomyopathy.During the perioperative period, beta-blockers and/or calcium channel blockers should be given; vasodilator and inotropic agents should be avoided due to the side effects on hemodynamics.

    We assessed pulmonary function in hereditary motor and sensory neuropathy. Fourteen neuropathy patients without spinal deformity (group 1), 14 with spinal deformity (group 2), and 16 individuals with idiopathic spinal deformity (group 3) matched to group 2 for age, height and Cobb angle, were included. Hereditary motor and sensory neuropathy severity was measured with Charcot-Marie-Tooth Neuropathy Score. All participants exhibited mild decrease in maximal inspiratory pressure at the mouth. One-way analysis of variance yielded significant main effects for lung volumes - slow vital capacity, forced expiratory volume in 1s, and total lung capacity (p'sSlow vital capacity and total lung capacity correlated with maximal inspiratory pressure at the mouth in group 2, whereas slow vital capacity correlated with muscle work in group 3 (p's<.05). Decreased lung volume may be due to impaired respiratory muscle strength in hereditary motor and sensory neuropathy with spinal deformity and due to spinal deformity in idiopathic patients.

    When compared to boys, girls have smaller vertebral cross-sectional area, which conveys a greater spinal flexibility, and a higher prevalence of adolescent idiopathic scoliosis. To test the hypothesis that small vertebral cross-sectional area and tall intervertebral disc height are structural characteristics of patients with adolescent idiopathic scoliosis. Using multiplanar imaging techniques, measures of vertebral cross-sectional area, vertebral height and intervertebral disc height in the lumbar spine were obtained in 35 pairs of girls and 11 pairs of boys with and without adolescent idiopathic scoliosis of the thoracic spine matched for age, height and weight. Compared to adolescents without spinal deformity, girls and boys with adolescent idiopathic scoliosis had, on average, 9.8% (6.68 ± 0.81 vs. 7.40 ± 0.99 cm{sup 2}; P = 0.0007) and 13.9% (8.22 ± 0.84 vs. 9.55 ± 1.61 cm{sup 2}; P = 0.009) smaller vertebral cross-sectional dimensions, respectively. Additionally, patients with adolescent idiopathic scoliosis had significantly greater values for intervertebral disc heights (9.06 ± 0.85 vs. 7.31 ± 0.62 mm and 9.09 ± 0.87 vs. 7.61 ± 1.00 mm for girls and boys respectively; both P ≤ 0.011). Multiple regression analysis indicated that the presence of scoliosis was negatively associated with vertebral cross-sectional area and positively with intervertebral disc height, independent of sex, age and body mass index. We provide new evidence that girls and boys with adolescent idiopathic scoliosis have significantly smaller vertebral cross-sectional area and taller intervertebral disc heights - two major structural determinants that influence trunk flexibility. With appropriate validation, these findings may have implications for the identification of children at the highest risk for developing scoliosis. (orig.)

    2008-03-01

    Full Text Available Abstract Idiopathic pulmonary fibrosis (IPF is a non-neoplastic pulmonary disease that is characterized by the formation of scar tissue within the lungs in the absence of any known provocation. IPF is a rare disease which affects approximately 5 million persons worldwide. The prevalence is estimated to be slightly greater in men (20.2/100,000 than in women (13.2/100,000. The mean age at presentation is 66 years. IPF initially manifests with symptoms of exercise-induced breathless and dry coughing. Auscultation of the lungs reveals early inspiratory crackles, predominantly located in the lower posterior lung zones upon physical exam. Clubbing is found in approximately 50% of IPF patients. Cor pulmonale develops in association with end-stage disease. In that case, classic signs of right heart failure may be present. Etiology remains incompletely understood. Some environmental factors may be associated with IPF (cigarette smoking, exposure to silica and livestock. IPF is recognized on high-resolution computed tomography by peripheral, subpleural lower lobe reticular opacities in association with subpleural honeycomb changes. IPF is associated with a pathological lesion known as usual interstitial pneumonia (UIP. The UIP pattern consists of normal lung alternating with patches of dense fibrosis, taking the form of collagen sheets. The diagnosis of IPF requires correlation of the clinical setting with radiographic images and a lung biopsy. In the absence of lung biopsy, the diagnosis of IPF can be made by defined clinical criteria that were published in guidelines endorsed by several professional societies. Differential diagnosis includes other idiopathic interstitial pneumonia, connective tissue diseases (systemic sclerosis, polymyositis, rheumatoid arthritis, forme fruste of autoimmune disorders, chronic hypersensitivity pneumonitis and other environmental (sometimes occupational exposures. IPF is typically progressive and leads to significant

    Full Text Available Background: Hypertrophic cardiomyopathy (HCM is a heart muscle disorder and is known to be inherited as an autosomal dominant trait. Mutations in several sarcomeric, cytoskeletal and mitochondrial genes have been reported in HCM. Though many cases of HCM are being identified, there is limited data regarding the epidemiology and genetics of HCM in India. Aim: Therefore the present study is envisaged at identifying the epidemiological variables in HCM and fitting a probability model assuming dominant mode of inheritance in HCM, which may in turn shed light on the heterogeneity of this complex disorder. Materials AND Methods: The 127 HCM cases were divided into subtypes based on pattern of hypertrophy. Chi square analysis, odds ratio, probability, relative frequency, penetrance and heritability estimates were calculated apart from epidemiological variables. Results: The HCM subtypes revealed the heterogeneous nature of the condition suggesting that the genes/mutations involved in their pathogenesis are different and this is supported by distinctive differences observed in their probability, heritability and penetrance estimates apart from epidemiological variables. An increased male preponderance was observed with the sex ratio being 3.7:1. The age at onset was found to be more than a decade early in familial cases (30 ± 10 yrs compared to non familial cases (44 ± 14 yrs. Chi square analysis revealed obstructive HCM to be following autosomal dominant mode of inheritance where as non-obstructive HCM was significantly deviating. The level of deviation was significantly high for the middle onset group compared to early and late onset groups, therefore this group may be considered as an admixture wherein genes/gene modifiers and environmental variables may be contributing to the heterogeneity and this is further supported by odds ratio. Conclusions: The study thus brings out the complexity of HCM and suggests that modes of inheritance other than

    Full Text Available A 34-year-old female presented with sudden onset of severe abdominal pain in a flank distribution. A large mass was palpable in the right upper quadrant on physical examination. Abdominal contrast-enhanced computed tomography showed a well-defined, right-sided, retroperitoneal cystic lesion located between the abdominal aorta and the inferior vena cava (IVC. The tumor size was 55 × 58 mm, and it compressed the gallbladder and the duodenum. Upper gastrointestinal radiography revealed a stricture of the second portion of the duodenum by the tumor. T2-weighted magnetic resonance imaging showed that the whole part was hyperintense with hypointense rims, but the inner was partially hypointense. Based on the radiological findings, the preoperative differential diagnosis included retroperitoneal teratoma, Schwannoma, abscess, and primary retroperitoneal tumor. On laparotomy, the tumor was located in the right retroperitoneal cavity. Kocher maneuver and medial visceral rotation, which consists of medial reflection of the upper part of right colon and duodenum by incising their lateral peritoneal attachments, were performed. Although a slight adhesion to the IVC was detected, the tumor was removed safely. Thin-section histopathology examination detected neither tumor tissues nor any tissues such as adrenal gland, ovarian tissue, or endometrial implants. The final pathological diagnosis was idiopathic retroperitoneal hematoma; the origin of the bleeding was unclear. The patient was discharged without any complication 5 days after the operation.

    2011-01-01

    Hypertrophic osteopathy is a hyperostotic syndrome of the appendicular skeleton that is most commonly associated with intrathoracic neoplasia or inflammation. The condition is rarely associated with intra-abdominal lesions. The majority of cases have occurred in dogs and human beings, with fewer cases reported in cats, horses, and other species. A 15-year-old male neutered Domestic Shorthair cat presented for swollen limbs and difficulty in ambulation. Radiographs and gross postmortem revealed severe periosteal hyperostosis of the diaphysis and metaphysis of all 4 limbs, including the humerus, radius, ulna, carpi, metacarpi, femur, tibia, tarsi, metatarsi, and phalanges. The axial skeleton was spared. Hyperostotic lesions were characterized microscopically by lamellar bony trabeculae separated by adipocytes and scant hematopoietic tissue. In several areas, fibrovascular connective tissue, woven bone, and islands of cartilage were also present. A 2.5 cm × 2.5 cm perirenal neoplasm compressed the left kidney and adrenal gland. This mass consisted of well-differentiated tubules of cuboidal epithelial cells and was most consistent with a renal tubular adenoma, because mitotic figures were rare, and no distant metastases were found. Thoracic pathology was absent. Hyperostosis was consistent with hypertrophic osteopathy secondary to the renal adenoma. The pathogenesis of hypertrophic osteopathy is uncertain, but predominant theories point to increased peripheral circulation and angiogenesis as a key initiating event. Recent literature highlights the potential role of vascular endothelial growth factor and platelet-derived growth factor in the human condition. The mechanism by which this renal adenoma caused hypertrophic osteopathy is unknown.

    The routine use of magnetic resonance imaging (MRI) in adolescent idiopathic scoliosis remains controversial, and current indications for MRI in idiopathic scoliosis vary from study to study. The purpose of this study was to demonstrate the prevalence of neural axis malformations and the clinical relevance of routine MRI studies in the evaluation of patients with adolescent idiopathic scoliosis undergoing surgical intervention without any neurological findings. A total of 249 patients with a diagnosis of idiopathic scoliosis were treated surgically between the years 2002 and 2007. A routine whole spine MRI analysis was performed in all patients. On the preoperative clinical examination, all patients were neurologically intact. There were 20 (8%) patients (3 males and 17 females) who had neural axis abnormalities on MRI. Three of those 20 patients needed additional neurosurgical procedures before corrective surgery; the remaining underwent corrective spinal surgery without any neurosurgical operations. Magnetic resonance imaging may be beneficial for patients with presumed idiopathic scoliosis even in the absence of neurological findings and it is ideally performed from the level of the brainstem to the sacrum.

    Full Text Available Abstract Background Scoliosis is the most common type of spinal deformity. In North American children, adolescent idiopathic scoliosis (AIS makes up about 90% of all cases of scoliosis. While its prevalence is about 2% to 3% in children aged between 10 to 16 years, girls are more at risk than boys for severe progression with a ratio of 3.6 to 1. The aim of the present study was to test the hypothesis that idiopathic scoliosis interferes with the mechanisms responsible for sensory-reweighting during balance control. Methods Eight scoliosis patients (seven female and one male; mean age: 16.4 years and nine healthy adolescents (average age 16.5 years participated in the experiment. Visual and ankle proprioceptive information was perturbed (eyes closed and/or tendon vibration suddenly and then returned to normal (eyes open and/or no tendon vibration. An AMTI force platform was used to compute centre of pressure root mean squared velocity and sway density curve. Results For the control condition (eyes open and no tendon vibration, adolescent idiopathic scoliosis patients had a greater centre of pressure root mean squared velocity (variability than control participants. Reintegration of ankle proprioception, when vision was either available or removed, led to an increased centre of pressure velocity variability for the adolescent idiopathic scoliosis patients whereas the control participants reduced their centre of pressure velocity variability. Moreover, in the absence of vision, adolescent idiopathic scoliosis exhibited an increased centre of pressure velocity variability when ankle proprioception was returned to normal (i.e. tendon vibration stopped. The analysis of the sway density plot suggests that adolescent idiopathic scoliosis patients, during sensory reintegration, do not scale appropriately their balance control commands. Conclusion Altogether, the present results demonstrate that idiopathic scoliosis adolescents have difficulty in

    Idiopathic oligoasthenoteratozoospermia (iOAT) affects approximately 30% of all infertile men. This mini-review discussed recent data in this field. Age, non-inflammatory functional alterations in post-testicular organs, infective agents (Chlamydia trachomatis, herpes virus and adeno-associated viruses), alterations in gamete genome, mitochondrial alterations, environmental pollutants and "subtle" hormonal alterations are all considered possible causes of iOAT.Increase of reactive oxygen species in tubules and in seminal plasma and of apoptosis are reputed to affect sperm concentration, motility and morphology. iOAT is commonly diagnosed by exclusion, nevertheless spectral traces of the main testicular artery may be used as a diagnostic tool for iOAT. The following can be considered therapies for iOAT: 1) tamoxifen citrate (20 mg/d) + testosterone undecanoate (120 mg/d) (pregnancy rate per couple/month [prcm]:3.8%); 2) folic acid (66 mg/d) + zinc sulfate (5 mg/d); 3) L-carnitine (2 g/d) alone or in combination with acetyl-L-carnitine (1 g/d) (prcm: 2.3%); and 4) both carnitines + one 30 mg cinnoxicam suppository every 4 days (prcm: 8.5%).Alpha-blocking drugs improved sperm concentration but not morphology, motility or pregnancy rate. Tranilast (300 mg/d) increased sperm parameters and pregnancy rates in an initial uncontrolled study. Its efficacy on sperm concentration (but not on sperm motility, morphology or prcm) was confirmed in subsequent published reports. The efficacy of tamoxifen + testosterone undecanoate, tamoxifen alone, and recombinant follicle-stimulating hormone is still a matter for discussion.

    Full Text Available A seven-year-old male neutered Irish setter was treated for a metastatic anal sac adenocarcinoma (ASAC and hypercalcaemia by complete surgical excision of the primary tumour and partial excision of the sublumbar lymph nodes. Further enlargement of the sublumbar lymph nodes was linked to recurrent hypercalcaemia 3 months after surgical treatment. Medical treatment with Toceranib and Clodronate showed modest results in the treatment of the tumour and the hypercalcaemia. Radiotherapy of the sublumbar lymph nodes and later concurrent carboplatin chemotherapy resulted in partial tumour remission with marked reduction in size of the lymph nodes and normalization of the calcaemia. Unfortunately, concurrently with subsequent relapse of the hypercalaemia, the dog developed hypertrophic osteopathy (HO and lumbar spinal metastasis and the dog was euthanized. To the authors’ knowledge, this is the second case of metastatic apocrine gland carcinoma of the anal sac associated with HO and the first case that describe the development of HO late in the stage of the disease.

    Spinal infections can be thought of as a spectrum of disease comprising spondylitis, discitis, spondylodiscitis, pyogenic facet arthropathy, epidural infections, meningitis, polyradiculopathy and myelitis. Radiological evaluations have gained importance in the diagnosis, treatment planning, treatment and treatment monitoring of the spinal infections. Conventional radiographs are usually the initial imaging study. The sensitivity and specificity of the plain radiographs are very low. The sensitivity of CT is higher while it lacks of specificity. Conventional CT has played minor role for the diagnosis of early spondylitis and disc space infection and for follow-up, researches are going on the value of MDCT. MRI is as sensitive, specific and accurate as combined nuclear medicine studies and the method of choice for the spondylitis. Low signal areas of the vertebral body, loss of definition of the end plates and interruption of the cortical continuity, destruction of the cortical margins are typical on T1WI whereas high signal of affected areas of the vertebral body and disc is typical on T2WI. Contrast is mandatory and increases conspicuity, specificity, and observer confidence in the diagnosis and facilitates the treatment planning. Contrast enhancement is the earliest sign and pathognomonic in the acute inflammatory episode and even in the subtle infection then persists to a varying degree for several weeks or months. The outcome of the treatment is influenced by the type of infection and by the degree of neurologic compromise before treatment. There is an increasing move away from surgical intervention towards conservative therapy, percutaneous drainage of abscess or both. It is therefore critical to monitor treatment response, particularly in the immuno-deficient population.

    The heart either hypertrophies or dilates in response to familial mutations in genes encoding sarcomeric proteins, which are responsible for contraction and pumping. These mutations typically alter calcium-dependent tension generation within the sarcomeres, but how this translates into the spectrum of hypertrophic versus dilated cardiomyopathy is unknown. By generating a series of cardiac-specific mouse models that permit the systematic tuning of sarcomeric tension generation and calcium fluxing, we identify a significant relationship between the magnitude of tension developed over time and heart growth. When formulated into a computational model, the integral of myofilament tension development predicts hypertrophic and dilated cardiomyopathies in mice associated with essentially any sarcomeric gene mutations, but also accurately predicts human cardiac phenotypes from data generated in induced-pluripotent-stem-cell-derived myocytes from familial cardiomyopathy patients. This tension-based model also has the potential to inform pharmacologic treatment options in cardiomyopathy patients.

  10. Prosthodontist contribution in treating post-burn hypertrophic facial scars

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available The formation of hypertrophic scars is common following healing of the burn wound, particularly in children. The face is one of the areas of the body most frequently affected by burns. Scar formation as a result of burn wounds leads to contraction of the formed granulation tissue, which causes both aesthetic and functional impairment for the patient. Scarring has major psychological and physical repercussions. Scarring on the face and visible regions of the body can be very distressing for the patient. Prevention of scars involves early and continuous use of a compressive orthesis. However, their efficacy is often limited to the facial region because of the contours of this area of body. This paper describes a clinical case of post-burn hypertrophic scars treated with silicone gel sheeting applied with pressure under custom made auto-polymerizing resin stent.

    2013-01-01

    Atrial myxoma is the most common primary cardiac tumor. Patients with atrial myxoma typically present with obstructive, embolic, or systemic symptoms; asymptomatic presentation is very rare. To our knowledge, isolated association of atrial myxoma with hypertrophic cardiomyopathy has been reported only once in the English-language medical literature. We report the case of an asymptomatic 71-year-old woman with known hypertrophic cardiomyopathy in whom a left atrial mass was incidentally identified on cardiac magnetic resonance images. After surgical excision of the mass and partial excision of the left atrial septum, histopathologic analysis confirmed the diagnosis of atrial myxoma. The patient was placed on preventive implantable cardioverter-defibrillator therapy and remained asymptomatic. The management of asymptomatic cardiac myxoma is a topic of debate, because no reports definitively favor either conservative or surgical measures. PMID:24082380

    Full Text Available Introduction Takotsubo syndrome (TKS is generally caused by a stressful condition, and it usually has a good prognosis after the recovery of left ventricular function. About 70% of the cases of hypertrophic cardiomyopathy may develop obstruction in the left ventricular outflow tract (LVOT, which is responsible for heart failure. Case Presentation We present a unique case where TKS occurred in a middle-aged male patient with hypertrophic obstructive cardiomyopathy (HOCM without a clearly identifiable initial stress trigger. Conclusions In the setting of acute left ventricular function depression in HOCM, a comprehensive differential diagnosis should be established. Treatment should be based on hemodynamic changes. After recovery, the prognosis is related to HOCM.

    Full Text Available We present the case 49-year-old unmarried woman treated at the hospital of Cienfuegos. The patient complained of weakness in the lower limbs and "numbness" (paresthesia of all four extremities, which improved slightly after treatment. A year later, the muscle weakness and paresthesia worsened, particularly in the upper limbs. She also developed hypopigmented skin lesions on the chest and abdomen. The investigation was initiated due to suspicion of hypertrophic polyneuropathy. A biopsy of the hypochromic lesions was performed, which led to the conclusion that the patient suffered from a hypertrophic polyneuropathy secondary to tuberculoid Hansen's disease. We decided to present this case since a neuropathy is usually slow, insidious and has a long course in these patients; however, leprosy reactions can lead to acute nerve damage, resulting in disabilities and deformities. Consequently, it is important to act quickly in order to avoid them.

    Myocardial ischemia in hypertrophic cardiomyopathy is multifactorial and explains the occurrence of angina, in about 50% of patients. The pathophysiology of myocardial ischemia may be explained by the increase of the ventricular mass and relative paucity of the coronary microcirculation; the elevated ventricular filling pressures and myocardial stiffness causing a compression of the coronary microvessels; the impaired coronary vasodilator flow reserve caused by anatomic and functional abnormalities; and the systolic compression of epicardial vessel (myocardial bridges). Myocardial ischemia must be investigated by perfusion scintigraphic methods since its presence influences the prognosis and has relevant clinical implications for management of patients. Patients with hypertrophic cardiomyopathy and documented myocardial ischemia usually need to undergo invasive coronary angiography to exclude the presence of concomitant atherosclerotic coronary disease.

  17. Current concepts and controversies on adolescent idiopathic scoliosis: Part I

    Full Text Available Adolescent idiopathic scoliosis is the most common spinal deformity encountered by General Orthopaedic Surgeons. Etiology remains unclear and current research focuses on genetic factors that may influence scoliosis development and risk of progression. Delayed diagnosis can result in severe deformities which affect the coronal and sagittal planes, as well as the rib cage, waistline symmetry, and shoulder balance. Patient′s dissatisfaction in terms of physical appearance and mechanical back pain, as well as the risk for curve deterioration are usually the reasons for treatment. Conservative management involves mainly bracing with the aim to stop or slow down scoliosis progression during growth and if possible prevent the need for surgical treatment. This is mainly indicated in young compliant patients with a large amount of remaining growth and progressive curvatures. Scoliosis correction is indicated for severe or progressive curves which produce significant cosmetic deformity, muscular pain, and patient discontent. Posterior spinal arthrodesis with Harrington instrumentation and bone grafting was the first attempt to correct the coronal deformity and replace in situ fusion. This was associated with high pseudarthrosis rates, need for postoperative immobilization, and flattening of sagittal spinal contour. Segmental correction techniques were introduced along with the Luque rods, Harri-Luque, and Wisconsin systems. Correction in both coronal and sagittal planes was not satisfactory and high rates of nonunion persisted until Cotrel and Dubousset introduced the concept of global spinal derotation. Development of pedicle screws provided a powerful tool to correct three-dimensional vertebral deformity and opened a new era in the treatment of scoliosis.

    Apical akinesis and dilation in the absence of obstructive coronary artery disease is a typical feature of stress-induced (takotsubo) cardiomyopathy, whereas apical hypertrophy is seen in apical-variant hypertrophic cardiomyopathy. We report the cases of 2 patients who presented with takotsubo cardiomyopathy and were subsequently found to have apical-variant hypertrophic cardiomyopathy, after the apical ballooning from the takotsubo cardiomyopathy had resolved. The first patient, a 43-year-old woman with a history of alcohol abuse, presented with shortness of breath, electrocardiographic and echocardiographic features consistent with takotsubo cardiomyopathy, and no significant coronary artery disease. An echocardiogram 2 weeks later revealed a normal left ventricular ejection fraction and newly apparent apical hypertrophy. The 2nd patient, a 70-year-old woman with pancreatitis, presented with chest pain, apical akinesis, and a left ventricular ejection fraction of 0.39, consistent with takotsubo cardiomyopathy. One month later, her left ventricular ejection fraction was normal; however, hypertrophy of the left ventricular apex was newly noted. To our knowledge, these are the first reported cases in which apical-variant hypertrophic cardiomyopathy was masked by apical ballooning from stress-induced cardiomyopathy.

    We report on a 13-year old girl with severe aplastic anemia and hypertrophic cranial pachymeningitis. She was admitted to our hospital with severe headache and vomiting. A computerized tomographic (CT) scan of the brain on the third day of symptoms showed a hyperdense area in the tentorial region. Magnetic resonance imaging (MRI) showed iso-intensity in the same tentorial region in T1- and T2-weighted images, and gadolinium enhancement of this region suggested a thickened dura mater. Initially, a diagnosis of subdural or subarachnoid hemorrhage was made. Since her platelet count was low (3000/microl) making the patient a poor-risk candidate for surgery, and the area was limited to the dura mater, conservative therapy, including glycerol administration and platelet transfusion, was carried out. Despite clinical improvement 10 days after admission without specific therapy, the iso-intense region on the left side of the tentorial region remained unchanged on MRI. On the other hand, the iso-intense area on the right side of the tentorial region became hyperdense on T1-weighted MRI images and was also enhanced by gadolinium. Cerebrospinal fluid findings were normal except for slightly elevated protein at 62 mg/dl. A diagnosis of hypertrophic cranial pachymeningitis of the tentorial dura mater with hemorrhage on the right side was made. Although hypertrophic cranial pachymeningitis is a rare disease, it must be considered in the differential diagnosis of severe headache in a case of aplastic anemia.

    Full Text Available A 4-year-old Criollo stallion was presented at the equine clinic of veterinary hospital of the Federal University of Santa Maria, RS, with a 30-day history of progressive weight loss, anemia and swelling of the forelimbs and face. Physical examination revealed that the swelling was firm and had a bone-like consistency, also radiographs showed extensive periosteal proliferation on the forelimb long bones that suggested hypertrophic osteopathy (Marie´s disease. Physical examinations identified no respiratory findings. However, during ultrasound examination, superficial lung disease was identified. The animal was treated with antibiotics and nonsteroidal anti-inflammatory drugs for 12 days. Due to a complete lack of response to this treatment, the horse was euthanized. At necropsy several granulomatous lesions were identified in the thorax, abdomen and testicular tunics. Bony proliferation was evident on many bones of the appendicular skeleton and face. Based on these findings the diagnosis of hypertrophic osteopathy associated with sarcoidosis was established. It is important to perform a thorough clinical examination and include hypertrophic osteopathy in the differential diagnosis of diseases that are accompanied by swelling of the face and limbs as edema from various causes, fibrous osteodystrophy, for example.

    Objective: To evaluate the surgical clinical results of hypertrophic obstructive cardiomyopathy. Methods: We retrospectively collected data on 24 patients who underwent surgical management in the past ten years in two hospitals in China and Madras Medical Mission in India. Myomectomy was carried out on all patients. Among them 3 patients underwent mitral valve replacement; 2 patients underwent mitral valve repair (anterior mitral leaflet plication); 2 patients underwent aortic valve replacement; 1 patient underwent aortic valve repair; 2 patients underwent aortic root replacement; 1 patient underwent Bentall's procedure and 1 patient underwent coronary artery bypass grafting because of a breached muscle bridge. Results: One patient died of post-operative heart failure. The mean follow-up time was 4.3 years. There was significant improvement in the symptomatic status. Sixteen patients were asymptomatic with good effort tolerance and only four patients had New York heart association (NYHA) Classes Ⅰ~Ⅱ due to associated valvular lesions. Conclusion: Our experience proved that symptomatic hypertrophic obstructive cardiomyopathy or non-symptomatic hypertrophic obstructive cardiomyopathy with combined heart disease is indication for surgery as surgical intervention could get better clinical results in this kind of patients compared with other non-surgical method because it beneficially reduces the systolic anterior motion (SAM) of the mitral valve leaflet, which could not be avoided by other non-surgical treatment.

    In this case report, we present familiar hypertrophic cardiomyopathy with age-dependent heterogeneity of the disease phenotype among the members of one family who carry the same mutation of the myosin-binding protein C gene. Phenotypic heterogeneity is common in patients with familial forms of hypertrophic cardiomyopathy, both in clinical expression and outcome. Compared with other noninvasive cardiac imaging modalities, cardiovascular magnetic resonance provides an opportunity to more accurately characterize the varying phenotypic presentations of hypertrophic cardiomyopathy.

    Patients with idiopathic scoliosis who had undergone posterior fusion by means of posterior multisegmented hook instrumentation were studied retrospectively. To present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion. Scoliosis is a three-dimensional deformity of the spine. The idiopathic cases usually exhibit a flattening of the sagittal curves, which had further deteriorated when the Harrington technique was used. The consequences included the flat back, angular increase of the lumbar lordosis below the fusion, and low back pain. Previous studies showed no or only moderate correction of thoracic hypokyphosis when using Cotrel-Dubousset instrumentation or its modifications were used. Harrington rod systems resulted in decreased lumbar lordosis in the fusion area and increased lordosis below the fusion. No background data were found concerning the effects of multisegmented hook instrumentation on the lumbar spine within and below the fusion. For this study, 306 patients with idiopathic scoliosis who had undergone posterior spinal fusion with multisegmented hook systems using the derotation maneuver were analyzed after a mean follow-up period of 5 years and 4 months. The coronal plane curvature, the sagittal plane projection of the thoracic kyphosis, and the lumbar lordosis within and below the fusion were evaluated. The average coronal plane correction was 67.1%. Analysis of the sagittal contours demonstrated that the preoperative thoracic hypokyphosis (less than 20 degrees between T4 and T12) increased by an average of 12 degrees, and that 55.1% of hypokyphotic backs were corrected to the normal range (20 degrees to 40 degrees ). In patients with frank lordosis (kyphosis less than 10 degrees ), the degree of correction was higher (average, 16 degrees ), but complete correction was achieved in only 38.5% of the cases. In patients with mild lordosis (kyphosis between 10 degrees and 20 degrees ), the

    Full Text Available Adolescent idiopathic scoliosis (AIS is a common orthopedic disorder of unknown etiology and pathogenesis. Melatonin and melatonin pathway dysfunction has been widely suspected to play an important role in the pathogenesis. Many different types of animal models have been developed to induce experimental scoliosis mimicking the pathoanatomical features of idiopathic scoliosis in human. The scoliosis deformity was believed to be induced by pinealectomy and mediated through the resulting melatonin-deficiency. However, the lack of upright mechanical spinal loading and inherent rotational instability of the curvature render the similarity of these models to the human counterparts questionable. Different concerns have been raised challenging the scientific validity and limitations of each model. The objectives of this review follow the logical need to re-examine and compare the relevance and appropriateness of each of the animal models that have been used for studying the etiopathogenesis of adolescent idiopathic scoliosis in human in the past 15 to 20 years.

    Full Text Available Hypertrophic degeneration of the inferior olive is mainly observed in patients developing palatal tremor (PT or oculopalatal tremor (OPT. This syndrome manifests as a synchronous tremor of the palate (PT and/or eyes (OPT that may also involve other muscles from the branchial arches. It is associated with hypertrophic inferior olivary degeneration that is characterized by enlarged and vacuolated neurons, increased number and size of astrocytes, severe fibrillary gliosis, and demyelination. It appears on MRI as an increased T2/FLAIR signal intensity and enlargement of the inferior olive. There are two main conditions in which hypertrophic degeneration of the inferior olive occurs. The most frequent, studied, and reported condition is the development of PT/OPT and hypertrophic degeneration of the inferior olive in the weeks or months following a structural brainstem or cerebellar lesion. This “symptomatic” condition requires a destructive lesion in the Guillain–Mollaret pathway, which spans from the contralateral dentate nucleus via the brachium conjunctivum and the ipsilateral central tegmental tract innervating the inferior olive. The most frequent etiologies of destructive lesion are stroke (hemorrhagic more often than ischemic, brain trauma, brainstem tumors, and surgical or gamma knife treatment of brainstem cavernoma. The most accepted explanation for this symptomatic PT/OPT is that denervated olivary neurons released from inhibitory inputs enlarge and develop sustained synchronized oscillations. The cerebellum then modulates/accentuates this signal resulting in abnormal motor output in the branchial arches. In a second condition, PT/OPT and progressive cerebellar ataxia occurs in patients without structural brainstem or cerebellar lesion, other than cerebellar atrophy. This syndrome of progressive ataxia and palatal tremor may be sporadic or familial. In the familial form, where hypertrophic degeneration of the inferior olive may not

    The posterior inferior cerebellar artery (PICA) is a vessel located between the intra- and extracranial circulation. The artery is characterized by a complex embryological development and numerous anatomical variants. The authors present a case of the PICA supplied by both a hypertrophic anterior spinal artery and a hypoplastic bulbar artery. This unusual arrangement somehow completes the list of previously published variants, and the spontaneous rupture of a related aneurysm confirmed the fragility of this network. The authors discuss anatomical and treatment considerations.

    Idiopathic interstitial pneumonias comprise 8 clinicopathological entities, most of them with a chronic course and various prognosis. Idiopathic pulmonary fibrosis is the most frequent and most severe of these. Computed tomography has an important role for its diagnosis. It can identify the corresponding pathological pattern of usual interstitial pneumonia in about 50 percent of cases. It can suggest differential diagnosis in other cases, most frequently fibrosing nonspecific interstitial pneumonia and chronic hypersensitivity pneumonitis. Imaging features should be integrated to clinical and available pathologic data during multidisciplinary team meetings involving physicians with a good knowledge of interstitial diseases. Some cases may be unclassifiable, but these could later be reclassified as new data may occur or imaging features may change. Surgical lung biopsy is being less frequently performed and an emerging less invasive technique, lung cryobiopsy, is under evaluation. Pleuroparenchymal fibroelastosis is a distinct entity only recently described, with uncertain prevalence and prognosis that seems being quite often associated to another pattern of interstitial pneumonia.

    Full Text Available Brett Ley, Harold R Collard Department of Medicine, Division of Pulmonary and Critical Care Medicine, University of California San Francisco, San Francisco, California, USA Abstract: Idiopathic pulmonary fibrosis is a chronic fibrotic lung disease of unknown cause that occurs in adults and has a poor prognosis. Its epidemiology has been difficult to study because of its rarity and evolution in diagnostic and coding practices. Though uncommon, it is likely underappreciated both in terms of its occurrence (ie, incidence, prevalence and public health impact (ie, health care costs and resource utilization. Incidence and mortality appear to be on the rise, and prevalence is expected to increase with the aging population. Potential risk factors include occupational and environmental exposures, tobacco smoking, gastroesophageal reflux, and genetic factors. An accurate understanding of its epidemiology is important, especially as novel therapies are emerging.

    The purpose of this study was to evaluate the effects of a devised posture management program based on the Theory of Planned Behavior in adolescents with mild idiopathic scoliosis. A quasi-experimental study was conducted. It involved a nonequivalent comparison group design with pretest and posttest. Forty-four female adolescents with mild idiopathic scoliosis participated; data from 35 participants (20 for the test group, 15 for the control group) were used for the final analyses. The devised posture management program ran for 6 weeks. Posture management behavioral determinants (attitude, subjective norms, perceived behavioral control, and behavioral intention) as cognitive outcomes and muscular strength and flexibility as physical outcomes were measured three times: at baseline, week 6 and week 8. Cobb's angle as another physical outcome was measured twice: at baseline and week 8. Descriptive analysis, repeated measures analysis of variance and t test were used for data analyses. Attitude, perceived control, and behavioral intention were consistently enhanced by the posture management program. The intervention increased flexibility and muscular strength and decreased Cobb's angle, which reduced spinal curvature. Frequency of posture management exercise showed a gradual increase in the test group. The results indicate that the posture management program is effective in maintaining posture management behavior in adolescents with mild idiopathic scoliosis for both cognitive and physical outcomes. The posture management program should be helpful in expanding the role of school nurses in improving the health status of adolescents with mild idiopathic scoliosis. Copyright © 2013.

    The objective is the description and summary of the current state of idiopathic scoliosis treatment with physical therapy based on new scientific knowledge and concluded from more than 15 years of experience as a leading physician in two well-known clinics specializing in the conservative treatment of scoliosis. Based on current scientific publications on physical therapy in scoliosis treatment and resulting from the considerable personal experience gained working with conservative treatment and consulting scoliosis patients (as inpatients and outpatients), the current methods of physical therapy have been compared and evaluated. Physical therapy according to Schroth and Vojta therapy are at present the most common and effective methods in the physical treatment of idiopathic scoliosis. These methods can be applied during inpatient or outpatient treatment or intensified in the practice of specialized therapists. As there are only a few scientific studies on this subject, the author's findings are based mainly on his own experiences of the conservative treatment of idiopathic scoliosis. Athough these experiences are the results of over 15 years of working in the field of therapy, and the Schroth method in combination with corrective bracing presents highly promising results, it would nevertheless be desirable to conduct detailed scientific studies to verify the effectiveness of conservative treatment.

    Huairong Ding

    Full Text Available OBJECTIVE: To report the outcomes of a posterior hybrid decompression protocol for the treatment of cervical spondylotic myelopathy (CSM associated with hypertrophic ligamentum flavum (HLF. BACKGROUND: Laminoplasty is widely used in patients with CSM; however, for CSM patients with HLF, traditional laminoplasty does not include resection of a pathological ligamentum flavum. METHODS: This study retrospectively reviewed 116 CSM patients with HLF who underwent hybrid decompression with a minimum of 12 months of follow-up. The procedure consisted of reconstruction of the C4 and C6 laminae using CENTERPIECE plates with spinous process autografts, and resection of the C3, C5, and C7 laminae. Surgical outcomes were assessed using Japanese Orthopedic Association (JOA score, recovery rate, cervical lordotic angle, cervical range of motion, spinal canal sagittal diameter, bone healing rates on both the hinge and open sides, dural sac expansion at the level of maximum compression, drift-back distance of the spinal cord, and postoperative neck pain assessed by visual analog scale. RESULTS: No hardware failure or restenosis was noted. Postoperative JOA score improved significantly, with a mean recovery rate of 65.3 ± 15.5%. Mean cervical lordotic angle had decreased 4.9 degrees by 1 year after surgery (P<0.05. Preservation of cervical range of motion was satisfactory postoperatively. Bone healing rates 6 months after surgery were 100% on the hinge side and 92.2% on the open side. Satisfactory decompression was demonstrated by a significantly increased sagittal canal diameter and cross-sectional area of the dural sac together with a significant drift-back distance of the spinal cord. The dural sac was also adequately expanded at the time of the final follow-up visit. CONCLUSION: Hybrid laminectomy and autograft laminoplasty decompression using Centerpiece plates may facilitate bone healing and produce a comparatively satisfactory prognosis for CSM patients

    Spinal epidural hematoma is an accumulation of blood in the potential space between the dura and bone. On unenhanced computed tomography epidural hemorrhage appears as a high-density spinal canal mass with variable cord compression. Magnetic resonance imaging is the modality of choice for evaluating spinal epidural hematoma and can demonstrate the extent of the hematoma and degree of cord compression. When treated surgically the outcome depends on the extent of preoperative neurological deficits and on the operative timing interval. (orig.) [German] Das spinale epidurale Haematom ist eine Blutansammlung zwischen Dura und Knochen. Die klinische Praesentation ist aehnlich dem akuten Bandscheibenvorfall, die Symptomatik ist allerdings in der Regel progredient. In der CT stellt sich ein frisches Haematom hyperdens dar. Die MRT ist die Methode der Wahl zur Diagnose spinaler epiduraler Haematome und kann die Ausdehnung sowie auch das Ausmass der Kompression darstellen. Die wichtigste Differenzialdiagnose vom epiduralen Haematom ist das epidurale Empyem. (orig.)

  11. Adolescent idiopathic scoliosis: natural history and long term treatment effects

    Full Text Available Abstract Adolescent idiopathic scoliosis is a lifetime, probably systemic condition of unknown cause, resulting in a spinal curve or curves of ten degrees or more in about 2.5% of most populations. However, in only about 0.25% does the curve progress to the point that treatment is warranted. Untreated, adolescent idiopathic scoliosis does not increase mortality rate, even though on rare occasions it can progress to the >100° range and cause premature death. The rate of shortness of breath is not increased, although patients with 50° curves at maturity or 80° curves during adulthood are at increased risk of developing shortness of breath. Compared to non-scoliotic controls, most patients with untreated adolescent idiopathic scoliosis function at or near normal levels. They do have increased pain prevalence and may or may not have increased pain severity. Self-image is often decreased. Mental health is usually not affected. Social function, including marriage and childbearing may be affected, but only at the threshold of relatively larger curves. Non-operative treatment consists of bracing for curves of 25° to 35° or 40° in patients with one to two years or more of growth remaining. Curve progression of ≥ 6° is 20 to 40% more likely with observation than with bracing. Operative treatment consists of instrumentation and arthrodesis to realign and stabilize the most affected portion of the spine. Lasting curve improvement of approximately 40% is usually achieved. In the most completely studied series to date, at 20 to 28 years follow-up both braced and operated patients had similar, significant, and clinically meaningful reduced function and increased pain compared to non-scoliotic controls. However, their function and pain scores were much closer to normal than patient groups with other, more serious conditions. Risks associated with treatment include temporary decrease in self-image in braced patients. Operated patients face the usual

    The hypertrophic chondrocytes lack the ability to proliferate, thus permitting matrix mineralization as well as vascular invasion from the bone in both the mandibular condyle and the epiphyseal cartilage. This study attempted to verify whether the histological appearance of the hypertrophic chondrocytes is in a steady state during postnatal development of the mouse mandibular condyle. Type X collagen immunohistochemistry apparently distinguished the fibrous layer described previously as the "articular zone," "articular layer," and "resting zone" from the hypertrophic zone. Interestingly, the ratio of the type X collagen-positive hypertrophic zone in the entire condyle seemed higher in the early stages but decreased in the later stages. Some apparently compacted cells in the hypertrophic zone showed proliferating cell nuclear antigen (PCNA) immunoreaction, indicating the potential for cell proliferation at the early stages. As the mice matured, in contrast, they further enlarged and assumed typical features of hypertrophic chondrocytes. Apoptotic cells were also discernible in the hypertrophic zone at the early but not later stages. Consistent with morphological configurations of hypertrophic chondrocytes, immunoreactions for alkaline phosphatase, osteopontin, and type I collagen were prominent at the later stage, but not the early stage. Cartilaginous matrices demonstrated scattered patches of mineralization at the early stage, but increased in their volume and connectivity at the later stage. Thus, the spatial and temporal occurrence of these immunoreactions as well as apoptosis likely reflect the prematurity of hypertrophying cells at the early stage, and imply a physiological relevance during the early development of the mandibular condyles.

    2013-01-01

    Background Pressure therapy improves hypertrophic scar healing,but the mechanisms for this process are not well understood.We sought to investigate the differential expression of matrix metalloproteinases (Mmps) and collagen in posttraumatic hypertrophic scar tissue with mechanical pressure and delineate the molecular mechanisms of pressure therapy for hypertrophic scars.Methods Fibroblast lines of normal skin and scar tissue were established and a mechanical pressure system was devised to simulate pressure therapy.Reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting assays were used to compare differences in the mRNA and protein expression of Mmps and collagen in scar fibroblasts before and after pressure therapy.Results The expression differed between the hypertrophic scar cell line and the normal cell line.RT-PCR assays showed that Collagen I,highly expressed in the hypertrophic scar cell line,decreased significantly after pressure therapy.Mmp2,Mmp9,and Mmp12 expression in the hypertrophic scar tissue increased significantly after pressure therapy (P <0.05).Western blotting assays further revealed that Mmp9 and Mmp12 expression increased significantly in the hypertrophic scar tissue after pressure therapy (P <0.05) but not Mmp2 expression (P >0.05).Conclusion Mechanical pressure induces degradation of Collagen Ⅰ in hypertrophic scar tissue by affecting the expression of Mmp9 and Mmp12.

    Seven elderly patients with hypertrophic obstructive cardiomyopathy (HOCM), who had the three following characteristics on echocardiograms 1) extremely thickened septum, 2) systolic anterior motion of the mitral valve, 3) mid systolic semi-closure of the aortic valve, were clinically evaluated. Ages ranged from 73 to 86 years old (average 78.9% yr.) and all were women. None had not a family history of hypertrophic cardiomyopathy but they had mild hypertension. Six patients showed a significant high voltage on the ST-segment and T-wave abnormalities ("strain" pattern). The left ventricular posterior wall as well as the septum was thickened in 5 and the remaining 2 showed asymmetrical septal hypertrophy (ASH) on echocardiograms. The left ventricular cavity was narrowed due to left ventricular hypertrophy and the shape of the left ventricular cavity was ovoid in all patients. The aorto-septal angles in these 7 patients were 80 degrees to 120 degrees. In addition, proximal septal bulge in all and anterior displacement of the mitral posterior leaflet due to the mitral ring calcification (MRC) in some patients contributed to the narrowing of the left ventricular outflow tract, and the mitral valve was pulled up toward the septum because of the good left ventricular systolic function (ejection fraction: 70 to 94% by echocardiography) and blood was ejected at a high velocity through a narrowed outflow tract (Venturi effect). Pressure gradients in the left ventricular outflow tract was 38 to 146 mmHg in 5 examined by cardiac catheterization. Biopsy specimens were obtained from 2 patients, showing hypertrophic myocytes (diameter: 20 to 30 micron) in 2 and mild disarray in 1.(ABSTRACT TRUNCATED AT 250 WORDS)

    Within the diverse spectrum of hypertrophic cardiomyopathy (HCM), a unique subgroup characterized by left ventricular enlargement and systolic dysfunction has emerged (defined as end-stage HCM [ES-HCM]). This underestimated entity provides challenging treatment strategies for extremely high risk of refractory heart failure and sudden cardiac death. Over the last 2 decades, the clinical features of ES-HCM have expanded and the underlying mechanisms gradually elucidated. Moreover, there is increasing evidence for early recognition of ES-HCM. New insights into early prevention and management will improve the clinical outcomes of this entity.

    A patient with florid hypertrophic pulmonary osteoarthropathy (HPOA) associated with metastatic nasopharyngeal carcinoma is presented. Despite the presence of metastatic disease in the thorax and in bone, the patient`s main symptom was severe pain from the HPOA, which was temporarily relieved by chemotherapy. Her disease subsequently progressed during chemotherapy and the pain became resistant to conventional treatment, including high dose morphine, non-steroidal anti-inflammatory agents and steroids. It was only with local radiation to the involved joints that the pain could be controlled. Our patient demonstrates that local radiotherapy is an option for the palliation of extreme HPOA. (author).

    Full Text Available Hypertrophic osteoarthropathy (HOA characterised by arthralgia, clubbing and periosteal proliferation of long bones, is rarely encountered in children and adolescents. Whereas in adults over 80% of cases are associated with malignancy, in children the majority of cases are due to non-neoplastic causes such as cystic fibrosis, bilary atresia and congenital heart disease. Up to 5% of adults with lung cancer demonstrate signs of HOA. However, lung cancer is extremely uncommon in children and young people. Here we report a case of lung adenocarcinoma in an 18 year old male associated with HOA present both at diagnosis and at subsequent disease progression.

    The gene family KCNE1-5, which encode modulating β-subunits of several repolarising K+-ion channels, has been associated with genetic cardiac diseases such as long QT syndrome, atrial fibrillation and Brugada syndrome. The minK peptide, encoded by KCNE1, is attached to the Z-disc of the sarcomere...... as well as the T-tubules of the sarcolemma. It has been suggested that minK forms part of an "electro-mechanical feed-back" which links cardiomyocyte stretching to changes in ion channel function.

    We present in this paper the architecture and some implementation details of a Document Management System and Workflow to help in the diagnosis of the hypertrophic cardiomyopathy, one of the most frequent genetic cardiovascular diseases. The system allows a gradual and collaborative creation of a knowledge base about the mutations associated with this disease. The system manages both the original documents of the scientific papers and the data extracted from these papers by the experts. Furthermore, a semiautomatic report generation module exploits this knowledge base to create high quality reports about the studied mutations.

    Long-term follow-up of untreated patients with adolescent idiopathic scoliosis (AIS) indicates that, with the exception of some extremely severe cases, AIS does not have a significant impact on quality of life and does not result in dire consequences. In view of the relatively benign nature of AIS and the long-term complications of surgery, the indications for treatment should be reviewed. Furthermore, recent studies have shown that scoliosis-specific exercises focusing on postural rehabilitation can positively influence the spinal curvatures in growing adolescents. Experiential postural re-education is a conservative, non-invasive approach, and its role in the management of AIS warrants further study. This article reviews current evidence for the inclusion of various forms of postural reeducation in the management of AIS. Recent comprehensive reviews have been researched including a manual and PubMed search for evidence regarding the effectiveness of physical/postural re-education/physiotherapy programs in growing AIS patients. This search revealed that there were few studies on the application of postural re-education in the management of AIS. These studies revealed that postural re-education in the form of exercise rehabilitation programs may have a positive influence on scoliosis; however, the various programs were difficult to compare. More research is necessary. There is at present Level 1 evidence for the effectiveness of Schroth scoliosis exercises in the management of AIS. Whether this evidence can be extrapolated to include other forms of scoliosis- pattern-specific exercises requires further investigation. Because corrective postures theoretically reduce the asymmetric loading of the spinal deformities and reverse the vicious cycle of spinal curvature progression, their integration into AIS programs may be beneficial and should be further examined.

    Selection of appropriate curve fusion levels for surgery in adolescent idiopathic scoliosis (AIS) is a complex and difficult task and, despite numerous publications, still remains a highly controversial topic. To evaluate a fuzzy-logic-based surgical planning tool by comparing the results suggested by the software with the average outcome recommended by a panel of 5 expert spinal deformity surgeons. It is hypothesized that, given the same information, the fuzzy-logic tool will perform as favorably as the surgeons. Proof-of-concept study evaluating the use of a fuzzy-logic-assisted surgical planning tool in AIS to select the appropriate spinal curve to be instrumented. A cohort of 30 AIS surgical cases with a main thoracic curve was used. Each case included standard measurements recorded from preoperative standing postero-anterior and lateral, supine side bending, and 1-year postoperative standing radiographs. Five experienced spinal deformity surgeons evaluated each case independently and gave their preferred levels of instrumentation and fusion. The cases were then presented to the fuzzy-logic tool to determine whether the high thoracic and/or lumbar curves were to be instrumented. For each case, a percentage value was obtained indicating inclusion/exclusion of the respective curves in the surgical instrumentation procedure. Kappa statistics was used to compare the model output and the average decision of the surgeons. Kappa values of 0.71 and 0.64 were obtained, respectively, for the proximal thoracic and lumbar curves models, thus suggesting a good agreement of the fusion recommendations made by the fuzzy-logic tool and the surgeons. Given the same information, the fuzzy-logic-assisted recommendation of the curve to be instrumented compared favorably with the collective decision of the surgeons. The findings thus suggest that a fuzzy-logic approach is helpful in assisting surgeons with the preoperative selection of curve instrumentation and fusion levels in AIS.

    Full Text Available Background: Hypertrophic scar causes physical and psychological problems. Thus understanding the factors related to the occurrence of hypertrophic scar tissue is needed. Little is known about its influencing factors in Indonesia, especially in Garut. Objective: This study aims to examine the relationships between hypertrophic scar and its influencing factors, and identify the most dominant factor of the occurrence of hypertrophic scars. Methods: This was an observational case control study using retrospective approach in Polyclinic of Surgery of Regional Public Hospital of dr. Slamet of Garut Regency. There were 40 samples recruited in this study by purposive sampling, which was divided to be case group (20 patients and control group (20 patients. Data were collected using Stony Brook Scar Evaluation Scale by observation and documentation of the medical records of patients. Data were analyzed using logistic regression analysis Results: Findings indicated that there were significant relationships between the surgical wound infection (p = 0.02, family history (p = 0.026, and type of suture (p = 0.043 with the occurrence of hypertrophic scars. The most dominant factor on the occurrence of hypertrophic scars was type of suture, acid polyglactin 910. The variables that had no significant relationships with the occurrence of hypertrophic scar tissue were age (p = 0.34, area of surgical wound (p = 0.177, and smoking habit (p = 0.479. Conclusion: There were significant relationships between infection of surgical wound, genetic history, the type of suture, and the occurrence of hypertrophic scar tissue. The most dominant factor that influenced the occurrence of hypertrophic scar tissue was the type of suture. Therefore, it is suggested to health professionals to modify the using of acid polyglactin 910 sutures, and nurses particularly need to provide the information regarding the family history and genetic-related hypertrophic scar, and prevent the

    Adolescent idiopathic scoliosis is a complex three-dimensional deformity of the spine characterized by deformities in the sagittal, coronal, and axial planes. Spinal fusion using pedicle screw instrumentation is a widely used method for surgical correction in severe (coronal deformity, Cobb angle > 45°) adolescent idiopathic scoliosis curves. Understanding the anatomic difference in the pedicles of patients with adolescent idiopathic scoliosis is essential to reduce the risk of neurovascular or visceral injury through pedicle screw misplacement. To use CT scans (1) to analyze pedicle anatomy in the adolescent thoracic scoliotic spine comparing concave and convex pedicles and (2) to assess the intra- and interobserver reliability of these measurements to provide critical information to spine surgeons regarding size, length, and angle of projection. Between 2007 and 2009, 27 patients with adolescent idiopathic scoliosis underwent thoracoscopic anterior correction surgery by two experienced spinal surgeons. Preoperatively, each patient underwent a CT scan as was their standard of care at that time. Twenty-two patients (mean age, 15.7 years; SD, 2.4 years; range, 11.6-22 years) (mean Cobb angle, 53°; SD, 5.3°; range, 42°-63°) were selected. Inclusion criteria were a clinical diagnosis of adolescent idiopathic scoliosis, female, and Lenke type 1 adolescent idiopathic scoliosis with the major curve confined to the thoracic spine. Using three-dimensional image analysis software, the pedicle width, inner cortical pedicle width, pedicle height, inner cortical pedicle height, pedicle length, chord length, transverse pedicle angle, and sagittal pedicle angles were measured. Randomly selected scans were remeasured by two of the authors and the reproducibility of the measurement definitions was validated through limit of agreement analysis. The concave pedicle widths were smaller compared with the convex pedicle widths at T7, T8, and T9 by 37% (3.44 mm ± 1.16 mm vs 4

    Using {sup 123}I-MIBG (metaiodobenzylguanidine) and {sup 201}Tl imagings, an examination concerning the relation between the hypertrophic region and its sympathetic nervous function was done. Subjects were 12 normal adults (4 males and 8 females, mean age 61.3 yr), 13 patients with asymmetrical hypertrophic cardiomyopathy (10 males and 3 females, 63.9 yr) and 13 patients with apical hypertrophy (9 males and 4 females, 67.2 yr). The SPECT apparatus was Toshiba two-gated gamma camera GCA 7200A. At 20 min and 3 hr after intravenous injection of 111 MBq of {sup 123}I-MIBG, myocardial SPECT and planar images were obtained with collimator LEHR under following conditions: photoelectric peak 159 KeV, window width 20%, matrix size 64 x 64 (256 x 256 for the planar image), step angle 6deg, 40 sec/step and 180deg for 1 camera. In another day, {sup 201}Tl SPECT and planar imagings were performed 10 min after intravenous injection of 111 MBq of {sup 201}Tl for the photoelectric peak 72 KeV under similar conditions to above. SPECT images were reconstructed using Butterworth filter and Shepp and Logan filter. Images were examined for the defect score, myocardium/mediastinum ratio, whole heart washout rate and regional washout rate. In the asymmetrical hypertrophic myopathy, abnormal sympathetic nerve function was recognized on the regions regardless of their disease severity while in the apical hypertrophy, abnormality was restricted on the apical region. Therefore, the two diseases were found different from each other from the aspect of sympathetic nerve functions. (K.H.)

    Full Text Available Objective: To learn about the experiences of adolescents diagnosed with idiopathic scoliosis. Method: Integrative review of the literature published within a specified time frame. Results: For both sexes, the predominant clinical symptom of this condition appears to be the negative effect that the deformity exerts on perceived self-image. Quantitative studies used numerical scores to assess perceptions of body image but did not analyse emotional aspects. Patients treated surgically were found to have a better self-image than patients treated with a brace. Quality of life was improved by a reduction in the magnitude of the curve. Conclusion: Spinal deformity exerts a psychological effect on adolescent girls.

    Although the use of corticosteroids in juvenile idiopathic arthritis (JIA) is now much more limited owing to the availability of methotrexate and biological agents, there are clinical scenarios where it is still indicated. For example, corticosteroids may be indicated for intraarticular injections to prevent joint deformities, as a "bridge" drug to relieve symptoms in polyarticular disease while waiting for methotrexate and biologics to exert their full therapeutic effects, and in the treatment of chronic iridocyclitis, macrophage activation syndrome, and systemic JIA, although the advent of interleukin (IL)-1 and IL-6 blockers has greatly reduced the latter indication.

    Full Text Available Abstract Background To elucidate further the pathogenesis of sporadic, idiopathic pulmonary arterial hypertension (IPAH and identify potential therapeutic avenues, differential gene expression in IPAH was examined by suppression subtractive hybridisation (SSH. Methods Peripheral lung samples were obtained immediately after removal from patients undergoing lung transplant for IPAH without familial disease, and control tissues consisted of similarly sampled pieces of donor lungs not utilised during transplantation. Pools of lung mRNA from IPAH cases containing plexiform lesions and normal donor lungs were used to generate the tester and driver cDNA libraries, respectively. A subtracted IPAH cDNA library was made by SSH. Clones isolated from this subtracted library were examined for up regulated expression in IPAH using dot blot arrays of positive colony PCR products using both pooled cDNA libraries as probes. Clones verified as being upregulated were sequenced. For two genes the increase in expression was verified by northern blotting and data analysed using Student's unpaired two-tailed t-test. Results We present preliminary findings concerning candidate genes upregulated in IPAH. Twenty-seven upregulated genes were identified out of 192 clones examined. Upregulation in individual cases of IPAH was shown by northern blot for tissue inhibitor of metalloproteinase-3 and decorin (P Conclusion Four of the up regulated genes, magic roundabout, hevin, thrombomodulin and sucrose non-fermenting protein-related kinase-1 are expressed specifically by endothelial cells and one, muscleblind-1, by muscle cells, suggesting that they may be associated with plexiform lesions and hypertrophic arterial wall remodelling, respectively.

    Full Text Available Background: Several studies have suggested higher incidence of osteoporosis in patients with idiopathic scoliosis in comparison with the normal population. The aim of this study was to assess the prevalence of low bone mass among adolescent girls with idiopathic scoliosis.Methods: In this cross-sectional study performed in shafa Hospital in Tehran, Iran during 2011-2012, we recruited fifty-seven 12- to-20-year old girls with idiopathic scoliosis and compared them with 100 age-matched healthy girls. The patients had no other diseases including neuromuscular disorders, congenital vertebral anomalies or a history of spinal surgery. Bone mineral densities (BMD of the hip and spine were evaluated and compared in all 157 participants using dual X-ray absorptiometry (DXA. Standard BMD (sBMD was also calculated at the lumbar spine. Results: Analysis of the data revealed that hip BMD was significantly (P=0.004 lower in patients with idiopathic scoliosis versus the controls. Moreover, BMD and sBMD of the Spine were also significantly lower in the patients (respectively, P=0.030 and P=0.030. Curve location had no effect on the values of hip BMD, spine BMD or spine sBMD (respectively, P=0.061 and P=0.274 and P=0.208.Finally, with more severe curves a lower bone mass was detected for sBMD and spine BMD (respectively, P=0.017 and P=0.016, but it was not significant for hip BMD (P=0.069.Conclusion: Adolescent girls with idiopathic scoliosis had lower bone mass compared with their healthy peers. The lower bone mass was correlated with the severity of the curve but not its location.

    Multiple myeloma (MM) is a malignancy of the plasma cell characterized by migration and localization to the bone marrow where cells then disseminate and facilitate the formation of bone lesions.It is associated with a constellation of disease manifestations,apart from osteolytic lesions,anemia and immuno-suppression due to loss of normal hematopoieric stem cell function,and cardiac amyloidosis due to monoclonal immunoglobulin secretion as well[1].Amyloid infiltration of the heart may frequently masquerade as hypertrophic cardiomyopathy (HCM).HCM,of which underlying cause and pathogenesis are largely unknown,is characterized by left and/or right ventricular hypertrophy,with predominant involvement of the interventricular septum in the absence of other causes of hypertrophy,such as hypertension or valvular heart diseases[2].While excessive hypertrophy of the myocardium is most commonly associated with myocyte hypertrophy,infiltration with amyloid always needs to be considered.In this report we presented two cases of multiple myeloma that mimicked hypertrophic cardiomyopathy so closely that it required bone marrow or endomyocardial biopsy to establish the diagnosis.

    2011-10-01

    Full Text Available Abstract Background The gene family KCNE1-5, which encode modulating β-subunits of several repolarising K+-ion channels, has been associated with genetic cardiac diseases such as long QT syndrome, atrial fibrillation and Brugada syndrome. The minK peptide, encoded by KCNE1, is attached to the Z-disc of the sarcomere as well as the T-tubules of the sarcolemma. It has been suggested that minK forms part of an "electro-mechanical feed-back" which links cardiomyocyte stretching to changes in ion channel function. We examined whether mutations in KCNE genes were associated with hypertrophic cardiomyopathy (HCM, a genetic disease associated with an improper hypertrophic response. Results The coding regions of KCNE1, KCNE2, KCNE3, KCNE4, and KCNE5 were examined, by direct DNA sequencing, in a cohort of 93 unrelated HCM probands and 188 blood donor controls. Fifteen genetic variants, four previously unknown, were identified in the HCM probands. Eight variants were non-synonymous and one was located in the 3'UTR-region of KCNE4. No disease-causing mutations were found and no significant difference in the frequency of genetic variants was found between HCM probands and controls. Two variants of likely functional significance were found in controls only. Conclusions Mutations in KCNE genes are not a common cause of HCM and polymorphisms in these genes do not seem to be associated with a propensity to develop arrhythmia

    Hypertrophic osteoarthropathy(HOA) is a clinical syndrome consisting of clubbing, periostitis and synovitis. Most frequent causes of hypertrophic osteoarthropathy are intrathoracic neoplasms, among which the bronchogenic carcinoma ranks the highest. But computed tomographic evaluation of intrathoracic neoplasm associated with HOA has been seldom reported. The purpose of this study is to evaluate CT findings of intrathoracic neoplasm associated with HOA, and to infer possible mechanism. Seven cases of intrathoracic neoplasm associated with HOA were included in our study. Diagnoses of HOA were made by Tc99m bone scintigraphy or plain radiography. The findings of chest CT scans were reviewed retrospectively, with main interests on their size, location and internal characteristics, ect. Seven cases of intrathoracic neoplasm consisted of five bronchogenic carcinomas and two thymic tumors. The size of intrathoracic tumors were relatively large ranging from 6cm to 13cm(average 8.0cm). All thoracic neoplasms showed wide pleural contact, and one of them invaded thoracic wall. The range of length of pleural contact was 5-18cm(average 9.9cm). All of seven patients had internal necrosis, and one of them showed cavitation in thoracic mass. Intrathoracic neoplasms associated with HOA had a tendency to be large, to contain internal necrosis, and to widely abut the thoracic pleura.

    Abstract We report the case of a 17‐year‐old female patient with known hypertrophic cardiomyopathy and a Wolff‐Parkinson‐White syndrome. She came to our department for further evaluation of a new diagnosed dilated cardiomyopathy characterized by an enlargement of the left ventricle and a fall in ejection fraction. Clinically, she complained about atypical chest pain, arrhythmic episodes with presyncopal events, and dyspnea (NYHA III) during the last 6 months. Non‐invasive and invasive examinations including magnetic resonance imaging, electrophysiological examinations, and angiography did not lead to a conclusive diagnosis. Therefore, endomyocardial biopsies (EMBs) were taken to investigate whether a specific myocardial disease caused the impairment of the left ventricular function. EMB analysis resulted in the diagnosis of a virus‐negative, active myocarditis. Based on this diagnosis, an immunosuppressive treatment with prednisolone and azathioprine was started, which led to an improvement of cardiac function and symptoms within 3 months after initiating therapy. In conclusion, we show that external stress triggered by myocarditis can induce a reversible transition from a hypertrophic cardiomyopathy to a dilated cardiomyopathy phenotype. This case strongly underlines the need for a thorough and invasive examination of heart failure of unknown causes, including EMB investigations as recommend by the actual ESC position statement.

    Encouraging family communication is an integral component of genetic counseling; therefore, we sought to identify factors impacting communication to family members at risk for Hypertrophic Cardiomyopathy (HCM). Participants (N = 383) completed an online survey assessing: 1) demographics (gender, genetic test results, HCM family history, and disease severity); 2) illness representations; 3) family functioning and cohesiveness; 4) coping styles; 5) comprehension of HCM autosomal dominant inheritance; and 6) communication of HCM risk information to at-risk relatives. Participants were a national sample of individuals with HCM, recruited through the Hypertrophic Cardiomyopathy Association. Data from 183 participants were analyzed using a logistic regression analysis, with family communication as a dichotomous dependent variable. We found that female gender and higher comprehension of autosomal dominant inheritance were significant predictors of participants' communication of HCM risk information to all their siblings and children. Our results suggest that utilizing interventions that promote patient comprehension (e.g., a teaching-focused model of genetic counseling) are important and may positively impact family communication within families with HCM.

    Study design Are there neuro-anatomical abnormalities associated with idiopathic scoliosis (IS)? Posterior Basicranium (PBA) reflects cerebellum growth and contains vestibular organs, two structures suspected to be involved in scoliosis. Objective The aim of this study was to compare posterior basicranium asymmetry (PBA) in Idiopathic scoliosis (IS) and normal subjects. Method: To measure the shape of PBA in 3D, we defined an intra-cranial frame of reference based on CNS and guided by embryology of the neural tube. Measurements concerned three directions of space referred to a specific intra cranial referential. Data acquisition was performed with T2 MRI (G.E. Excite 1.5T, mode Fiesta). We explored a scoliosis group of 76 women and 20 men with a mean age of 17, 2 and a control group of 26 women and 16 men, with a mean age of 27, 7. Results: IS revealed a significant asymmetry of PBA (Pr>|t|<.0001) in 3 directions of space compared to the control group. This asymmetry was more pronounced in antero-posterior...

    Full Text Available Atherosclerosis is a chronic inflammatory disease of the arteries. Clinical consequences of the atherosclerotic process occur in the adult population, however atherosclerotic process begins in childhood. The classic risk factors for atherosclerosis include obesity, dyslipidaemia, age, gender or family history. In recent years, attention has been drawn to the similarity between atherosclerotic inflammatory processes and inflammatory changes in the course of systemic connective tissue disease, in particular systemic lupus etythematosus (SLE or rheumatoid arthritis (RA. There is also observed the similarity of the pathogenetic background of development of atherosclerosis and juvenile idiopathic arthritis (JIA. Elevated levels of pro-inflammatory cytokines are observed in the course of juvenile idiopathic arthritis. Also homocysteine concentrations, which may play a significant role in the development of atherosclerotic lesions, are observed higher in patients with JIA. Some studies revealed higher carotid intima-media thickness (IMT index values in children with JIA. In view of the fact that atherosclerotic process begins as early as in childhood, the introduction of appropriate preventive measures in children is a matter of utmost importance.

    Spinal cord herniation following surgery is an extremely uncommon clinical condition with very few reports in published literature. This condition usually occurs as a spontaneous idiopathic phenomenon often in the thoracic spine or following a scenario of post traumatic spinal cord/nerve root injury. Rarely has it been reported following spinal cord tumor surgery. To document a case of cervical spinal cord herniation as a late onset complication following spinal cord tumor surgery with an atypical presentation of monoparesis. Case report. We describe the clinical presentation, operative procedure, post operative outcome and review of literature of this rare clinical condition. A 57-year-old man presented with right upper limb monoparesis due to a spinal cord herniation 6 years after a cervical intradural meningioma excision. The patients underwent surgery to reduce the herniation and duroplasty with subsequent complete resolution of symptoms. Spinal cord herniation must be considered as differential diagnosis in scenarios of spinal cord tumor excision presenting with late onset neurological deficit. These cases may present as paraparesis, Brown-sequard syndrome and rarely as in our case as monoparesis.

    Idiopathic scoliosis (IS) affects 3% of children worldwide, yet the mechanisms underlying this spinal deformity remain unknown. Here we show that ptk7 mutant zebrafish, a faithful developmental model of IS, exhibit defects in ependymal cell cilia development and cerebrospinal fluid (CSF) flow. Transgenic reintroduction of Ptk7 in motile ciliated lineages prevents scoliosis in ptk7 mutants, and mutation of multiple independent cilia motility genes yields IS phenotypes. We define a finite developmental window for motile cilia in zebrafish spine morphogenesis. Notably, restoration of cilia motility after the onset of scoliosis blocks spinal curve progression. Together, our results indicate a critical role for cilia-driven CSF flow in spine development, implicate irregularities in CSF flow as an underlying biological cause of IS, and suggest that noninvasive therapeutic intervention may prevent severe scoliosis.

    Chronic urticaria is the most common skin diseases, characterized by chronic cutaneous lesions which severely debilitates patients in several aspects of their everyday life. Vitamin D is known to exert several actions in the immune system and to influence function and differentiation of mast cells, central role players in the pathogenesis of chronic idiopathic urticaria. This study was performed to evaluate the relationship between vitamin D levels and susceptibility to chronic idiopathic urticaria. One hundred and fourteen patients with chronic idiopathic urticaria were recruited in this study along with one hundred and eighty seven sex-matched and age-matched healthy volunteers as the control group. For each patient, urticaria activity score was calculated and autologous serum skin test was done. Vitamin D metabolic statue was measured in serum as 25 hydroxyvitamin D using enzyme immunoassay method. Patients with chronic idiopathic urticaria significantly showed lower levels of vitamin D. Vitamin D deficiency was significantly associated with increased susceptibility to chronic idiopathic urticaria. There was a significant positive correlation between vitamin D levels and urticaria activity score. This study showed that patients with chronic idiopathic urticaria had reduced levels of vitamin D, while vitamin D deficiency could increase susceptibility to chronic idiopathic urticaria.

    Cerebral palsy patients who undergo posterior spinal instrumentation for scoliosis are at a greater risk of surgical site infection compared to adolescents with idiopathic scoliosis. Many infecting organisms are reported. Risk factors include patients' specific factors, nutritional status as well as surgery related factors. Although surgical management is still controversial, it is always based on irrigation and debridement followed or not by implant removal. The purpose of this paper is to review the pathophysiology of surgical site infection in this patient population and to propose a treatment algorithm, based on a thorough review of the current literature and personal experience.

    Objective To study the function of focal adhesion kinase (FAK) in the formation of hyper-trophic scar and its interrelationship with integrin α1. Methods Original fibroblasts from human hypertrophic scar and human normal dermis were cultured, and immanocytochemistry was applied to detect localization of expres-sion of FAK and integrin α1 in hypertrophic scar and human normal skin fibroblasts. The expression of integrin α1 was detected before and after FAK antibody blocking hypertrophic scar fibroblasts (HSFB) 48 h later. Meanwhile the collagen synthesis was evaluated by [3H] -proline incorporation and HSFB cell proliferation was measured by MTT method. Results The expression of FAK and integrin α1 of hypertrophic scar fibroblasts was higher than that of the normal skin fibroblasts significantly (P <0. 01). The expression of integrinct, was reduced after FAK be-ing blocked (P<0.01). Meanwhile the collagen synthesis of human scar-derived fibroblasts by [3H] -proline incor-poration was depressed respectively (P<0.01). The cell proliferation was inhibited by using 1:100 and 1:200 FAK antibody with MTT method (P<0.01). Conclusion FAK is the key point of signal transmission pathway medi-ated by integrin α1, which regulates protein synthesis of integrin α1, it may play an important role in the prolifera-tion and constriction of hypertrophic scar. FAK antibody can inhibit the collagen synthesis and cell proliferation of hypertrophic scar fibroblasts.

    Alterations in sensory processing have been demonstrated in chronic low back and neck pain. However, it has not been yet systematically summarized how early these changes occur in spinal pain. This systematic review examines the available literature measuring somatosensory function in acute (<6 weeks) and subacute (6-12 weeks) spinal pain. The protocol for this review has been registered on the International Prospective Register of Systematic Reviews (PROSPERO). An electronic search of 4 databases was conducted to retrieve studies assessing somatosensory function by quantitative sensory testing in adults with spinal pain of up to 12 weeks duration. Two reviewers independently screened the studies and assessed the risk of bias. Studies were grouped according to spinal pain condition (whiplash injury, idiopathic neck pain, and nonspecific low back pain), and, where possible, meta-analyses were performed for comparable results. Fifteen studies were included. Sources of bias included lack of assessor blinding, unclear sampling methods, and lack of control for confounders. We found that: (1) there is consistent evidence for thermal and widespread mechanical pain hypersensitivity in the acute stage of whiplash, (2) there is no evidence for pain hypersensitivity in the acute and subacute stage of idiopathic neck pain, although the body of evidence is small, and (3) hyperalgesia and spinal cord hyperexcitability have been detected in early stages of nonspecific low back pain, although evidence about widespread effects are conflicting. Future longitudinal research using multiple sensory modalities and standardized testing may reveal the involvement of somatosensory changes in the development and maintenance of chronic pain.

    Idiopathic subglottic stenosis is a narrowing of the trachea at the level of the cricoid cartilage of unknown etiology. It is a rare condition for which the real incidence has never been established owing to the difficulty of making the diagnosis. Although there is a female preponderance, no familial cases have been reported in the literature. We describe two pairs of sisters as well as a mother and daughter presenting with idiopathic subglottic stenosis. All known causes of tracheal stenosis were excluded, including prolonged intubation, surgery, autoimmune and inflammatory disorders, infection and gastroesophageal reflux disease. These are the first cases reported in the literature that suggest a genetic predisposition for idiopathic subglottic stenosis.

    Full Text Available BACKGROUND Meningiomas of the spinal canal are common tumours with the incidence of 25 percent of all spinal cord tumours. But multiple spinal canal meningiomas are rare in compare to solitary lesions and account for 2 to 3.5% of all spinal meningiomas. Most of the reported cases are both intra cranial and spinal. Exclusive involvement of the spinal canal by multiple meningiomas are very rare. We could find only sixteen cases in the literature to the best of our knowledge. Exclusive multiple spinal canal meningiomas occurring in the first two decades of life are seldom reported in the literature. We are presenting a case of multiple spinal canal meningiomas in a young patient of 17 years, who was earlier operated for single lesion. We analysed the literature, with illustration of our case. MATERIALS AND METHODS In September 2016, we performed a literature search for multiple spinal canal meningiomas involving exclusively the spinal canal with no limitation for language and publication date. The search was conducted through http://pubmed.com, a wellknown worldwide internet medical address. To the best of our knowledge, we could find only sixteen cases of multiple meningiomas exclusively confined to the spinal canal. Exclusive multiple spinal canal meningiomas occurring in the first two decades of life are seldom reported in the literature. We are presenting a case of multiple spinal canal meningiomas in a young patient of 17 years, who was earlier operated for solitary intradural extra medullary spinal canal meningioma at D4-D6 level, again presented with spastic quadriparesis of two years duration and MRI whole spine demonstrated multiple intradural extra medullary lesions, which were excised completely and the histopathological diagnosis was transitional meningioma. RESULTS Patient recovered from his weakness and sensory symptoms gradually and bladder and bowel symptoms improved gradually over a period of two to three weeks. CONCLUSION Multiple

    Sarcoidosis is a multisystem, granulomatous disease of unknown etiology often seen in young adults, with cardiac involvement in more than one-quarter of sarcoid patients. The clinical presentation of cardiac sarcoid depends upon the location and extent of myocardium involved. Although cardiac sarcoid may produce asymmetrical septal hypertrophy, it is most commonly considered in the differential diagnosis of dilated cardiomyopathy. The hypertrophic stage of cardiac sarcoid is rarely seen. We describe a case of cardiac sarcoid in a young patient wherein a distinctive appearance of the cardiac sarcoid spectrum from "hypertrophic" stage to thinned/scarred stage, masquerading as hypertrophic cardiomyopathy followed by dilated cardiomyopathy, is demonstrated.

    The prevalence of congenital heart disease in infants with Down syndrome is 40%, compared with 0.3% in children who have normal chromosomes. Atrioventricular and ventricular septal defects are often associated with chromosomal aberrations, such as in trisomy 21, whereas hypertrophic cardiomyopathy is chiefly thought to be secondary to specific gene mutations. We found only one reported case of congenital hypertrophic cardiomyopathy and atrioventricular septal defect in an infant with Down syndrome. Here, we report atrioventricular septal defect, hypertrophic cardiomyopathy, and pulmonary vein stenosis in a neonate with Down syndrome-an apparently unique combination. In addition, we discuss the relevant medical literature.

    Hypertrophic cardiomyopathy (HCM) is an autosomal dominant heart disease that is the most common genetic cardiac disorder. The disease is characterized by excessive thickening of the left ventricular myocardium. The anterior portion of the interventricular ventricular septum is often involved. Asymmetric hypertrophy of apical site, left ventricular free wall, and right ventricle are less common in hypertrophic cardiomyopathy that occur in 1% cases. We report a case of a patient with an unusual type of hypertrophic cardiomyopathy and Wolf Parkinson White (WPW) presenting with pulmonary edema.

    Scoliosis progression during adolescence is closely related to patient maturity. Maturity has various indicators, including chronological age, height and weight changes, and skeletal and sexual maturation. It is not certain which of these indicators correlates most strongly with scoliosis progression. The purpose of the present study was to evaluate various maturity measurements and how they relate to scoliosis progression. Physically immature girls with idiopathic scoliosis were evaluated every six months through their growth spurt with serial spinal radiographs; hand skeletal ages; Oxford pelvic scores; Risser sign determinations; height; weight; sexual staging; and serologic studies of the levels of selected growth factors, estradiol, bone-specific alkaline phosphatase, and osteocalcin. These measurements were then correlated with the curve-acceleration phase. The period and pattern of curve acceleration began during Risser stage 0 for all patients. Skeletal maturation scores derived with the use of the Tanner-Whitehouse-III RUS method, particularly those for the metacarpals and phalanges, were superior to all other indicators of maturity. Regression of the scores provided good estimates of maturity relative to the period of curve progression (Pearson r = 0.93). The initiation of this period occurred simultaneously with digital changes from Tanner-Whitehouse-III stage F to G. At this stage, curves also separated into rapid, moderate, and low-acceleration patterns, with specific curve types in the rapid and moderate-acceleration groups. The low-acceleration group was not confined to a specific curve type. The curve-acceleration phase separates curves into various types of curve progression. The Tanner-Whitehouse-III RUS scores are highly correlated with timing relative to the curve-acceleration phase and provide better maturity determination and prognosis determination during adolescence than the other parameters tested.

    The diagnosis of hypertrophic cardiomyopathy (HCM) is based on clinical, echocardiographic and in some cases genetic findings. However, prognostication remains limited except in the subset of patients with high-risk indicators for sudden cardiac death. Additional methods are needed for risk stratification and to guide clinical management in HCM. We reviewed the available data regarding natriuretic peptides and troponins in HCM. Plasma levels of natriuretic peptides, and to a lesser extent serum levels of troponins, correlate with established disease markers, including left ventricular thickness, symptom status, and left ventricular hemodynamics by Doppler measurements. As a reflection of left ventricular filling pressure, natriuretic peptides may provide an objective measure of the efficacy of a specific therapy. Both natriuretic peptides and troponins predict clinical risk in HCM independently of established risk factors, and their prognostic power is additive. Routine measurement of biomarker levels therefore may be useful in the clinical evaluation and management of patients with HCM.

    2012-03-01

    Surgical site infection (SSI) occurs at the site of surgery within 1 month of an operation or within 1 year of an operation if a foreign body is implanted as part of the surgery. Most SSIs (about 70%) are superficial infections involving the skin and subcutaneous tissues only. The remaining infections are more serious and can involve tissues under the skin, organs, or implanted material. Hypertrophic scars( HSs) occur frequently on particular sites, including the anterior chest wall. The anterior chest wall is frequently subjected to skin stretching caused by the natural daily movements of the body. Most cases of SSIs and HSs can be prevented by (1) suture technique modification to prevent high stretching tension and ischemia, and (2) appropriate wound care after surgery. It would be useful to avoid subjecting wounded skin to sustained mechanical force, thereby permitting the wound to rest and heal normally.

    Hypertrophic cardiomyopathy (HCM) is the most common monogenic genetic cardiac disease, with an estimated prevalence of 1:500 in the general population. Clinically, HCM is characterized by hypertrophy of the left ventricle (LV) walls, especially the septum, usually asymmetric, in the absence of any cardiac or systemic disease that leads to a secondary hypertrophy. The clinical course of the disease has a large inter- and intrafamilial heterogeneity, ranging from mild symptoms of heart failure late in life to the onset of sudden cardiac death at a young age and is caused by a mutation in one of the genes that encode a protein from the sarcomere, Z-disc or intracellular calcium modulators. Although many genes and mutations are already known to cause HCM, the molecular pathways that lead to the phenotype are still unclear. This review focus on the molecular mechanisms of HCM, the pathways from mutation to clinical phenotype and how the disease's genotype correlates with phenotype.

    Full Text Available In nerve entrapment syndromes, an electrodiagnostic study during physical examination would usually suffice to assess localization of injury. However, in daily clinical practice, sometimes it may be necessary to depict the insight; in other words to use an imaging tool. From this point of view, with its manifold advantages, ultrasound (US is superior to other imaging technologies such as magnetic resonance imaging (MRI. According to a study, US increased the sensitivity of electrodiagnostic studies from 78% to 98%. By presenting a patient with cubital tunnel syndrome caused by hypertrophic scarring, we wanted to highlight the complementary role of US in nerve entrapment syndromes in confirming the entrapment, as well as the usefulness of it in the follow-up period of burn patients.

    Hypertrophic osteoarthropathy (HOA) is an incompletely understood syndrome characterized by digital clubbing and periosteal proliferation of long bones and it is commonly associated with primary lung tumors. Bone scintigraphy is a sensitive method in detecting HOA and characteristic findings have been reported. We present the case of a man with newly diagnosed non-small cell lung cancer, unremarkable clinical examination and blood tests and no digital clubbing. During disease staging, however, bone scintigraphy showed intense calcaneal cortical proliferation bilaterally without involvement of other parts of the skeleton. Cortical reaction of both calcanei resolved significantly after chemotherapy. This case indicates that HOA may manifest with isolated calcaneal periostitis bilaterally, which is a new addition to the literature.

    Despite the significant progress that has been made in identifying disease-associated mutations, the utility of the Hypertrophic Cardiomyopathy (HCM) genetic test is limited by a lack of understanding of the background genetic variation inherent to these sarcomeric genes in seemingly healthy subjects. This study represents the first comprehensive analysis of genetic variation in 427 ostensibly healthy individuals for the HCM genetic test using the “Gold Standard” Sanger sequencing method validating the background rate identified in the publically available exomes. While mutations are clearly over-represented in disease, a background rate as high as ~5% among healthy individuals prevents diagnostic certainty. To this end, we have identified a number of estimated predictive value-based associations including gene-specific, topology, and conservation methods generating an algorithm aiding in the probabilistic interpretation of an HCM genetic test.

    A 26-year-old male patient gradually developed muscular atrophy of the right lower leg over a two-year period. Neurological examination revealed absent Achilles tendon reflex and muscular atrophy of the right lower leg and right hamstring muscles. Conduction velocity of the F waves was delayed in the right posterior tibial nerve. A computerized tomography scan and magnetic resonance imaging revealed a mass lesion along the proximal segment of the right sciatic nerve. Exploration revealed a fusiformly swollen sciatic nerve. Histological examination showed that a swollen segment of the sciatic nerve was filled with onion-bulb formations of perineurial cells, consistent with the diagnosis of localized hypertrophic neuropathy. This condition should be added to several etiologies of monomelic amyotrophy. Electrophysiological studies and neuroimaging techniques were useful in obtaining differential diagnosis.

    Hypertrophic cardiomyopathy (HCM) is a genetic cardiac disease primarily caused by mutations in genes coding for sarcomeric proteins. A molecular-genetic etiology can be established in ~60% of cases. Evolutionarily conserved mitochondrial DNA (mtDNA) haplogroups are susceptibility factors for HCM....... Several polymorphic mtDNA variants are associated with a variety of late-onset degenerative diseases and affect mitochondrial function. We examined the role of private, non-haplogroup associated, mitochondrial variants in the etiology of HCM. In 87 Danish HCM patients, full mtDNA sequencing revealed 446......>G, and MT-CYB: m.15024G>A, p.C93Y remained. A detailed analysis of these variants indicated that none of them are likely to cause HCM. In conclusion, private mtDNA mutations are frequent, but they are rarely, if ever, associated with HCM....

    2014-08-01

    Full Text Available Hypertrophic cardiomyopathy (HCM has been recently recognized as the most common inherited cardiovascular disorder, affecting 1 in 500 adults worldwide. HCM is characterized by myocyte hypertrophy resulting in thickening of the ventricular wall, myocyte disarray, interstitial and/or replacement fibrosis, decreased ventricular cavity volume and diastolic dysfunction. HCM is also the most common cause of sudden death in the young. A large proportion of patients diagnosed with HCM have mutations in sarcomeric proteins. However, it is unclear how these mutations lead to the cardiac phenotype, which is variable even in patients carrying the same causal mutation. Abnormalities in calcium cycling, oxidative stress, mitochondrial dysfunction and energetic deficiency have been described, constituting the basis of therapies in experimental models of HCM and HCM patients. This review focuses on evidence supporting the role of cellular metabolism and mitochondria in HCM.

A hypertrophic lateral frenum in the upper left canine region was detected. A great depression in the gingival rodet separated the anterior maxillary segment from the posterior one and also decreased the lip mobility in this region. A frenectomy was performed when the patient was 11 months old and the clinical follow-up was done up to the age of 30 months. There was normalization in the vestibular insertion of the lateral frenum, lip mobility, physiological development of the maxilla, and eruption of the upper incisors, canines, and first primary molars. Infants should go to a dental examination precociously in order to detect possible congenital and development alterations.

    We report cases of serious arrhythmias associated with apical hypertrophic cardiomyopathy (AHCM). Thirty-one patients were referred to our institute to undergo further assessment of their AHCM from 1988 to 1999. Three patients with nonsustained ventricular tachycardia demonstrated an {sup 123}I-MIBG regional reduction in the tracer uptake. In two patients with ventricular fibrillation (VF), the findings from {sup 123}I-MIBG imaging revealed regional sympathetic denervation in the inferior and lateral regions. Electrophysiologic study demonstrated reproducible induction of VF in aborted sudden death and presyncopal patients, resulting in the need for an implantable defibrillator device and amiodarone in each patient. Patients with refractory atrial fibrillation with a rapid ventricular response suffered from serious congestive heart failure. A prudent assessment and strategy in patients with this disease would be indispensable in avoiding a disastrous outcome. (author)

  10. Hypertrophic cardiomyopathy and ultra-endurance running - two incompatible entities?

    Directory of Open Access Journals (Sweden)

    Wilson Mathew G

    2011-11-01

    Full Text Available Abstract Regular and prolonged exercise is associated with increased left ventricular wall thickness that can overlap with hypertrophic cardiomyopathy (HCM. Differentiating physiological from pathological hypertrophy has important implications, since HCM is the commonest cause of exercise-related sudden cardiac death in young individuals. Most deaths have been reported in intermittent 'start-stop' sports such as football (soccer and basketball. The theory is that individuals with HCM are unable to augment stroke volume sufficiently to meet the demands of endurance sports and are accordingly 'selected-out' of participation in such events. We report the case of an ultra-endurance athlete with 25 years of > 50 km competitive running experience, with genetically confirmed HCM; thereby demonstrating that these can be two compatible entities.

    Full Text Available Idiopathic inflammatory myopathies (IIM are a heterogeneous group of disease with complex clinical features. It has been sub-classified as: (1 Dermatomyositis, (2 Polymyositis, and (3 Inclusion body myositis (IBM. Nowadays, there are some studies in literature suggest necrotizing autoimmune myopathy and immune-mediated necrotizing myopathy should also be added to this group of disease. There is a debate in the diagnosis of IIMs and up until now, about 12 criteria systems have been proposed. Some of the criteria systems have been used widely such as Griggs et al.'s proposal for IBM. Clinical findings, autoantibodies, enzymes, electrophysiological, and muscle biopsy findings are diagnostic tools. Because of diseases' complexity, none of the findings are diagnostic alone. In this study, we discussed the diagnostic criteria of IMMs and described detailed morphological features. [J Interdiscipl Histopathol 2016; 4(2.000: 41-45

    2017-01-01

    Renal infarction is a rare cause of referral to the emergency department, with very low estimated incidence (0.004%–0.007%). Usually, it manifests in patients aged 60–70 with risk factors for thromboembolism, mostly related to heart disease, atrial fibrillation in particular. We report a case of idiopathic segmental renal infarction in a 38-year-old patient, presenting with acute abdominal pain with no previous known history or risk factors for thromboembolic diseases. Because of its aspecific clinical presentation, this condition can mimic more frequent pathologies including pyelonephritis, nephrolithiasis, or as in our case appendicitis. Here we highlight the extremely ambiguous presentation of renal infarct and the importance for clinicians to be aware of this condition, particularly in patients without clear risk factors, as it usually has a good prognosis after appropriate anticoagulant therapy.

    Idiopathic arterial calcification in infancy is usually fatal with death in early life and diagnosis at post mortem. This report describes a unique, late presentation with hypertension and cardiac failure in a child aged 33 months, found to have widespread arterial calcification at radiological imaging. The calcium-phosphate axis was normal and there was no other demonstrable cause for calcification. Additionally, the histological features of arterial calcification at renal biopsy paralleled the findings in infants with this disorder. The late presentation in this case is unusual and has not been previously reported. Ultrasound and CT are sensitive for calcification, and the disease should be suspected in children presenting with cardiac or respiratory manifestations and features of arterial calcification, where no metabolic cause is established.

    Full Text Available Many patients with idiopathic pulmonary fibrosis (IPF complain of chronic refractory cough. Chronic cough is a distressing and disabling symptom with a major impact on quality of life. During recent years, progress has been made in gaining insight into the pathogenesis of cough in IPF, which is most probably “multifactorial” and influenced by mechanical, biochemical and neurosensory changes, with an important role for comorbidities as well. Clinical trials of cough treatment in IPF are emerging, and cough is increasingly included as a secondary end-point in trials assessing new compounds for IPF. It is important that such studies include adequate end-points to assess cough both objectively and subjectively. This article summarises the latest insights into chronic cough in IPF. It describes the different theories regarding the pathophysiology of cough, reviews the different methods to assess cough and deals with recent and future developments in the treatment of cough in IPF.

    Control of disease activity and recovery of function are major issues in the treatment of children and adolescents suffering from juvenile idiopathic arthritis (JIA). Functional therapies including physiotherapy are important components in the multidisciplinary teamwork and each phase of the disease requires different strategies. While in the active phase of the disease pain alleviation is the main focus, the inactive phase requires strategies for improving motility and function. During remission the aim is to regain general fitness by sports activities. These phase adapted strategies must be individually designed and usually require a combination of different measures including physiotherapy, occupational therapy, massage as well as other physical procedures and sport therapy. There are only few controlled studies investigating the effectiveness of physical therapies in JIA and many strategies are derived from long-standing experience. New results from physiology and sport sciences have contributed to the development in recent years. This report summarizes the basics and main strategies of physical therapy in JIA.

    2009-12-01

    Building on seminal studies of the last 20 years, genetic testing for hypertrophic cardiomyopathy (HCM) has become a clinical reality in the form of targeted exonic sequencing of known disease-causing genes. This has been driven primarily by the decreasing cost of sequencing, but the high profile of genome-wide association studies, the launch of direct-to-consumer genetic testing, and new legislative protection have also played important roles. In the clinical management of hypertrophic cardiomyopathy, genetic testing is primarily used for family screening. An increasing role is recognized, however, in diagnostic settings: in the differential diagnosis of HCM; in the differentiation of HCM from hypertensive or athlete's heart; and more rarely in preimplantation genetic diagnosis. Aside from diagnostic clarification and family screening, use of the genetic test for guiding therapy remains controversial, with data currently too limited to derive a reliable mutation risk prediction from within the phenotypic noise of different modifying genomes. Meanwhile, the power of genetic testing derives from the confidence with which a mutation can be called present or absent in a given individual. This confidence contrasts with our more limited ability to judge the significance of mutations for which co-segregation has not been demonstrated. These variants of "unknown" significance represent the greatest challenge to the wider adoption of genetic testing in HCM. Looking forward, next-generation sequencing technologies promise to revolutionize the current approach as whole genome sequencing will soon be available for the cost of today's targeted panel. In summary, our future will be characterized not by lack of genetic information but by our ability to effectively parse it.

    AIM To determine acute kidney in jury (AKI) incidence and potential risk factors of AKI in children undergoing spinal instrumentation surgery. METHODS AKI incidence in children undergoing spinal instrumentation surgery at British Columbia Children’s Hospital between January 2006 and December 2008 was determined by the Acute Kidney Injury Networ classification using serum creatinine and urine output criteria. During this specific time period, all patients following spinal surgery were monitored in the pediatric intensive care unit and had an indwelling Foley catheter permitting hourly urine output recording. Cases of AKI were identified from our database. From the remaining cohort, we selected group-matched controls that did not satisfy criteria for AKI. The controls were matched for sex, age and underlying diagnosis (idiopathic vs non-idiopathic scoliosis). RESULTS Thirty five of 208 patients met criteria for AKI with an incidence of 17% (95%CI: 12%-23%). Of all children who developed AKI, 17 (49%) developed mild AKI (AKI Stage 1), 17 (49%) developed moderate AKI (Stage 2) and 1 patient (3%) met criteria for severe AKI (Stage 3). An inverse relationship was observed with AKI incidence and the amount of fluids received intra-operatively. An inverse relationship was observed with AKI incidence and the amount of fluids received intra-operatively classified by fluid tertiles: 70% incidence in those that received the least amount of fluids vs 29% that received the most fluids (> 7.9, P = 0.02). Patients who developed AKI were more frequently exposed to nephrotoxins (non steroidal anti inflammatory drugs or aminoglycosides) than control patients during their peri-operative course (60% vs 22%, P < 0.001). CONCLUSION We observed a high incidence of AKI following spinal instrumentation surgery in children that is potentially related to the frequent use of nephrotoxins and the amount of fluid administered peri-operatively.

    Case report. To report a very unusual spinal meningioma, mimicking an intramedullary spinal tumor. Spinal meningiomas, usually associated with signs and symptoms of cord or nerve root compression, are generally encountered in women aged over 40. Radiologic diagnosis is often established by their intradural extramedullary location on magnetic resonance images. A 60-year-old woman had a 6-month history of progressive weakness in her upper extremities, difficulty in walking, and cervical pain radiating through both arms. Neurologic examination revealed motor strength deficiency in all her extremities, with extensor reflexes, clonus, and bilateral hyper-reflexiveness. A sensory deficit was present all over her body. Magnetic resonance images revealed that the spinal cord appeared expanded with an ill-defined, homogeneously contrast-enhanced, lobulated, eccentric mass at the C1-C3 level. The patient was operated with a preliminary diagnosis of an intramedullary tumor. At surgery, the mass was found to be extramedullary, and gross total resection was performed. Histopathological examination revealed a meningioma characterized by the presence of fibrous and meningothelial components. The patient was able to ambulate with a cane, and extremity strength and sensation improved 2 months after surgery. Spinal meningiomas can mimic intramedullary tumors, and should be considered in differential diagnosis of intradural tumors with atypical appearance.

    Full Text Available We report two cases of spontaneous spinal epidural hematoma with different clinical presentations without precipitating factors and a brief review of the literature. Our case first developed acute and had progressive cervical spinal cord signs that determined emergency decompressive laminectomy. On the other hand, the second patient, who was chronic, was operated almost five months after the initial symptoms and the radiological diagnosis was a large facet cyst. Early surgical intervention is the chosen treatment for spontaneous spinal epidural hematomas. Spinal surgeons should bear in mind that spontaneous spinal epidural hematomas may have different clinical presentations according to their location in order to perform a differential diagnosis.Fueron relatados dos casos de hematoma epidural espinal espontáneo con diferentes presentaciones clínicas sin factores precipitantes, y fue hecha una breve revisión de la literatura.

    Idiopathic scoliosis predominantly afflicts adolescents. Adolescents with mild curvatures do not generally have any symptoms. However spinal fusion is indicated when the deformity exceeds 45°. Treatment is thus necessary to prevent and/or reduce the progression of curvatures to that below which surgery is indicated. Conservative treatment of adolescent idiopathic scoliosis includes observation, scoliosis-specific exercises (SSE) and bracing. There is increasing evidence suggesting that SSE and brace treatment can significantly limit the progression of spinal curvatures. In growing adolescents with curvatures more than 20°, bracing is indicated and should be used in conjunction with SSE. The effectiveness of bracing varies according to the type of brace applied to the patient. In general rigid braces are preferable to soft flexible braces, as the latter falls short of halting curvatures progression. Also, preliminary evidence suggests that asymmetric braces which enable over-correction provide more correction when compared with symmetrical braces. Recently it has also been reported that high quality bracing can also reduce curvatures exceeding 45° in over 70% of growing adolescents. This new knowledge might possibly increase the threshold of surgical indications to beyond 50° or above in the near future.

    Objectives Hypertrophic cardiomyopathy, a primary disorder of the myocardium, is the most common cardiac disease in cats. However, determination of myocardial deformation with two-dimensional speckle-tracking echocardiography in cats with various stages of hypertrophic cardiomyopathy has not yet been reported. This study was designed to measure quantitatively multidirectional myocardial deformations of cats with hypertrophic cardiomyopathy. Methods Thirty-two client-owned cats with hypertrophic cardiomyopathy and 14 healthy cats serving as controls were enrolled and underwent assessment of myocardial deformation (peak systolic strain and strain rate) in the longitudinal, radial and circumferential directions. Results Longitudinal and radial deformations were reduced in cats with hypertrophic cardiomyopathy, despite normal systolic function determined by conventional echocardiography. Cats with severely symptomatic hypertrophic cardiomyopathy also had lower peak systolic circumferential strain, in addition to longitudinal and radial strain. Conclusions and relevance Longitudinal and radial deformation may be helpful in the diagnosis of hypertrophic cardiomyopathy. Additionally, the lower circumferential deformation in cats with severe hypertrophic cardiomyopathy may contribute to clinical findings of decompensation, and seems to be related to severe cardiac clinical signs. Indices of multidirectional myocardial deformations by two-dimensional speckle-tracking echocardiography may be useful markers and help to distinguish between cats with hypertrophic cardiomyopathy and healthy cats. Additionally, they may provide more detailed assessment of contractile function in cats with hypertrophic cardiomyopathy.

    Background: extracranial seeding of glioblastoma multiforme (GBM) is very rare and its development depends on several factors. This case report describes two patients suffering from GBM with spinal seeding. In both cases, the anatomic localization of the primary tumor close to the cerebrospinal fluid (CSF) was the main factor for spinal seeding. Case reports: two patients with GBM and spinal seeding are presented. After diagnosis of spinal seeding, both patients were highly symptomatic from their spinal lesions. Case 1 experienced severe pain requiring opiates, and case 2 had paresis of lower limbs as well as urinary retention/incontinence. Both patients were treated with spinal radiation therapy. Nevertheless, they died 3 months after diagnosis of spinal seeding. Results: in both patients the diagnosis of spinal seeding was made at the time of cranial recurrence. Both tumors showed close contact to the CSF initially. Even though the patients underwent intensive treatment, it was not possible to keep them in a symptom-free state. Conclusion: because of short survival periods, patients deserve optimal pain management and dedicated palliative care. (orig.)

  16. Spinal tuberculosis: A review

    Garg, Ravindra Kumar; Somvanshi, Dilip Singh

    2011-01-01

    Spinal tuberculosis is a destructive form of tuberculosis. It accounts for approximately half of all cases of musculoskeletal tuberculosis. Spinal tuberculosis is more common in children and young adults. The incidence of spinal tuberculosis is increasing in developed nations. Genetic susceptibility to spinal tuberculosis has recently been demonstrated. Characteristically, there is destruction of the intervertebral disk space and the adjacent vertebral bodies, collapse of the spinal elements, and anterior wedging leading to kyphosis and gibbus formation. The thoracic region of vertebral column is most frequently affected. Formation of a ‘cold’ abscess around the lesion is another characteristic feature. The incidence of multi-level noncontiguous vertebral tuberculosis occurs more frequently than previously recognized. Common clinical manifestations include constitutional symptoms, back pain, spinal tenderness, paraplegia, and spinal deformities. For the diagnosis of spinal tuberculosis magnetic resonance imaging is more sensitive imaging technique than x-ray and more specific than computed tomography. Magnetic resonance imaging frequently demonstrates involvement of the vertebral bodies on either side of the disk, disk destruction, cold abscess, vertebral collapse, and presence of vertebral column deformities. Neuroimaging-guided needle biopsy from the affected site in the center of the vertebral body is the gold standard technique for early histopathological diagnosis. Antituberculous treatment remains the cornerstone of treatment. Surgery may be required in selected cases, e.g. large abscess formation, severe kyphosis, an evolving neurological deficit, or lack of response to medical treatment. With early diagnosis and early treatment, prognosis is generally good. PMID:22118251

    Hypertrophic adenoids with otitis media with effusion is a common infectious disease and present a serious otological problem in children. Cytokines, potent inflammatory mediators, play important role in the initiation of immunological response in otitis media. Adenoids excised due to hypertrophy with or without chronic otitis media with effusion were used to isolate mononuclear cells. Secretion of cytokines by non-stimulated and PHA-stimulated cells was determined by specific ELISAs. We found a significant increase in the production of IL-5 and TNF-α secreted by adenoidal cells of children with otitis media with effusion compared to group with hypertrophic adenoids. No differences were found in the secretion of IL-8, IL-6, and IL-10 between these two groups of patients. Our results suggest a difference between the immunological responses in the course of hypertrophic adenoids with otitis media as compared to hypertrophic adenoids.

    Spontaneous spinal cord herniation through a dural defect is an unusual condition. This entity has been probably underestimated before the introduction of MRI. We report a case of a 49-year-old man with a progressive Brown-Sequard syndrome. MRI and CT myelogram showed a ventrally displaced spinal cord at level T6-T7 and expansion of the posterior subarachnoid space. Through a laminectomy, a spinal cord herniation was identified and reduced. The anterior dural defect was repaired with a patch of lyophilized dura. The patient recovered muscle power but there was no improvement of the sensory disturbance. The diagnosis of spontaneous spinal cord herniation must be considered when progressive myelopathy occurs in middle-aged patients, without signs of spinal cord compression and typical radiological findings. Surgical treatment may halt the progressive deficits and even yield improvement in many cases.

    Full Text Available Background: Hypertrophic cardiomyopathy is a rather common hereditary disease with an autozomal dominant character, caused by mutations of genes that code for proteins of the cardiac sarcomere. The observed prevalence of this disease is much lower in pediatric patients compared to adults, because it’s late gene expression. Hypertrophic cardiomyopathy presenting in infancy has been shown to have a very high mortality.

    Idiopathic ophthalmodynia and idiopathic rhinalgia were described a few years ago. These conditions seem specific pain syndromes with a distinctive location in the eye or in the nose. We aimed to present a new prospective series in order to verify the consistency of these syndromes. We performed a descriptive study of all patients referred to our regional neurologic clinics from 2010 to 2014 because of facial pain exclusively felt in the eye or in the nose fulfilling the proposed diagnostic criteria for idiopathic ophthalmodynia and idiopathic rhinalgia. There were 9 patients with idiopathic ophthalmodynia and 7 patients with idiopathic rhinalgia, with a clear female preponderance, and a mean age at onset in the fifth decade. The pain was usually moderate and the temporal pattern was generally chronic. Only one patient reported accompaniments (hypersensitivity to the light and to the flow of air in the symptomatic eye). Preventive treatment with amitriptyline, pregabalin, or gabapentin was partially or totally effective. The clinical features of this new series parallels those of the original description, thus indicating that both idiopathic ophthalmodynia and idiopathic rhinalgia have clear-cut clinical pictures with excellent consistency both inter- and intra-individually. © 2015 American Headache Society.

    Introduction Despite its high incidence and severe morbidity, the physiopathogenesis of adolescent idiopathic scoliosis (AIS) is still unknown. Here, we looked for early anomalies in AIS which are likely to be the cause of spinal deformity and could also be targeted by early treatments. We focused on the vestibular system, which is suspected of acting in AIS pathogenesis and which exhibits an end organ with size and shape fixed before birth. We hypothesize that, in adolescents with idiopathic scoliosis, vestibular morphological anomalies were already present at birth and could possibly have caused other abnormalities. Materials and Methods The vestibular organ of 18 adolescents with AIS and 9 controls were evaluated with MRI in a prospective case controlled study. We studied lateral semicircular canal orientation and the three semicircular canal positions relative to the midline. Lateral semicircular canal function was also evaluated by vestibulonystagmography after bithermal caloric stimulation. Results The left lateral semicircular canal was more vertical and further from the midline in AIS (p = 0.01) and these two parameters were highly correlated (r = -0.6; p = 0.02). These morphological anomalies were associated with functional anomalies in AIS (lower excitability, higher canal paresis), but were not significantly different from controls (p>0.05). Conclusion Adolescents with idiopathic scoliosis exhibit morphological vestibular asymmetry, probably determined well before birth. Since the vestibular system influences the vestibulospinal pathway, the hypothalamus, and the cerebellum, this indicates that the vestibular system is a possible cause of later morphological, hormonal and neurosensory anomalies observed in AIS. Moreover, the simple lateral SCC MRI measurement demonstrated here could be used for early detection of AIS, selection of children for close follow-up, and initiation of preventive treatment before spinal deformity occurs.

    Full Text Available A osteoartropatia hipertrófica primária é uma síndrome rara, caracterizada pela presença de baqueteamento digital de mãos e pés, aumento das extremidades e de tecidos periarticulares secundários à proliferação óssea, fisionomia facial grosseira, dor e edema articular. A forma primária representa 3 a 5% de todos os casos de osteoartropatia hipertrófica e tem como fatores etiológicos influência genética, anormalidade da atividade fibroblástica e alteração no suprimento sanguíneo periférico. Apresenta evolução crônica e insidiosa, alternando fases de exacerbação com períodos assintomáticos. As manifestações clínicas são variáveis. A denominação síndrome completa é reservada aos casos com paquidermia (espessamento cutâneo da face e couro cabeludo, periostite e cutis vertici gyrata; síndrome incompleta, quando não há envolvimento do couro cabeludo; e frustra, quando se observa paquidermia com periostite mínima ou ausente. Os autores descrevem um homem branco de 39 anos diagnosticado com a forma primária da osteoartropatia hipertrófica. A partir do relato de caso, discutem-se características clínicas, radiológicas e a abordagem terapêutica dessa patologia.Primary hypertrophic osteoarthropathy is a rare syndrome, consisting of clubbed hands, fingers, and feet digits; enlarged extremities secondary to periarticular and bone proliferation; thickened facial skin; painful and swollen joints. The idiopathic form represents 3 to 5 per cent of all cases of hypertrophic osteoarthropaty. Genetic influence, abnormal fibroblasts activity, and changes of the peripherical blood flow appear to be significant on the pathogenesis. Clinical manifestations are variable: the term complete syndrome is used for the patient with pachydermia, coarsening of the face skin and scalp, periostitis, and cutis verticis gyrata; the incomplete form, when there is no sparing of the scalp; and the frusted form for pachydermia with

    Hypertrophic scarring is a frequent fibroproliferative complication following deep dermal burns leading to impaired function and lifelong disfigurement. Decorin reduces fibrosis and induces regeneration in many tissues, and is significantly downregulated in hypertrophic scar and normal deep dermal fibroblasts. It was hypothesized that microRNAs in these fibroblasts downregulate decorin and blocking them would increase decorin and may prevent hypertrophic scarring. Lower decorin levels were fo...

    Objective:The present study was designed to use an in vivo rabbit ear scar model to investigate the efficacy of systemic administration of endostatin in inhibiting scar formation.Methods:Eight male New Zealand white rabbits were randomly assigned to two groups.Scar model was established by making six full skin defect wounds in each ear.For the intervention group,intraperitoneal injection of endostatin was performed each day after the wound healed (about 15 d post wounding).For the control group,equal volume of saline was injected.Thickness of scars in each group was measured by sliding caliper and the scar microcirculatory perfusion was assessed by laser Doppler flowmetry on Days 15,21,28,and 35 post wounding.Rabbits were euthanatized and their scars were harvested for histological and proteomic analyses on Day 35 post wounding.Results:Macroscopically,scars of the control group were thicker than those of the intervention group.Significant differences between the two groups were observed on Days 21 and 35 (p<0.05).Scar thickness,measured by scar elevation index (SEI) at Day 35 post wounding,was significantly reduced in the intervention group (1.09±0.19) compared with the controls (1.36±0.28).Microvessel density (MVD) observed in the intervention group (1.73±0.94) was significantly lower than that of the control group (5.63±1.78)on Day 35.The distribution of collagen fibers in scars treated with endostatin was relatively regular,while collagen fibers in untreated controls were thicker and showed disordered alignment.Western blot analysis showed that the expressions of type Ⅰ collagen and Bcl-2 were depressed by injection of endostatin.Conclusions:Our results from the rabbit ear hypertrophic scar model indicate that systemic application of endostatin could inhibit local hypertrophic scar formation,possibly through reducing scar vascularization and angiogenesis.Our results indicated that endostatin may promote the apoptosis of endothelial cells and block their

    Full Text Available Purpose. Adolescent idiopathic scoliosis (AIS, the most common pediatric spinal deformity, is considered a complex genetic disease. Causing genes and pathogenesis of AIS are still unclear. This study was designed to identify differentially expressed long noncoding RNAs (lncRNAs involving the pathogenesis of AIS. Methods. We first performed comprehensive screening of lncRNA and mRNA in AIS patients and healthy children using Agilent human lncRNA + mRNA Array V3.0 microarray. LncRNAs expression in different AIS patients was further evaluated using quantitative PCR. Results. A total of 139 lncRNAs and 546 mRNAs were differentially expressed between AIS patients and healthy control. GO and Pathway analysis showed that these mRNAs might be involved in bone mineralization, neuromuscular junction, skeletal system morphogenesis, nucleotide and nucleic acid metabolism, and regulation of signal pathway. Four lncRNAs (ENST00000440778.1, ENST00000602322.1, ENST00000414894.1, and TCONS_00028768 were differentially expressed between different patients when grouped according to age, height, classification, severity of scoliosis, and Risser grade. Conclusions. This study demonstrates the abnormal expression of lncRNAs and mRNAs in AIS, and the expression of some lncRNAs was related to clinical features. This study is helpful for further understanding of lncRNAs in pathogenesis, treatment, and prognosis of AIS.

    Full Text Available Idiopathic pulmonary fibrosis or cryptogenic fibrosing alveolitis is a form of chronic, progressive interstitial lung disease causing scarring of lung tissue and usually affect adults. Treatment is usually aimed at controlling inflammation and thus slowing the process of fibrosis. With only few patients responding to treatment and the disease being ultimately fatal with poor progression, the underlying lesion was considered to be fibrotic rather than inflammatory. Fibrotic foci, deposition of collagen, and lack of inflammatory cells are a predominant finding. Pirfenidone and N-acetyl cysteine are the only effective pharmacotherapy available till date. Interim results of PANTHER Trial clearly indicate more risk with triple therapy. However, in Indian patients, trial of steroid therapy may be tried when there is doubt of chronic hypersensitivity pneumonitis. BIBF 1120 has also shown positive results in Phase II clinical trial and shows a positive response in deteriorating lung function. Supplemental oxygen, education of patient, pulmonary rehabilitation, and Streptococcus pneumoniae and influenza vaccine are the most important supportive care. Pulmonary rehabilitation should be used as a treatment in the majority of patients. [Int J Basic Clin Pharmacol 2014; 3(5.000: 761-763

    Idiopathic normal pressure hydrocephalus (iNPH) is a late-onset surgically alleviated, progressive disease. We characterize a potential familial subgroup of iNPH in a nation-wide Finnish cohort of 375 shunt-operated iNPH-patients. The patients were questionnaired and phone-interviewed, whether they have relatives with either diagnosed iNPH or disease-related symptomatology. Then pedigrees of all families with more than one iNPH-case were drawn. Eighteen patients (4.8%) from 12 separate pedigrees had at least one shunt-operated relative whereas 42 patients (11%) had relatives with two or more triad symptoms. According to multivariate logistic regression analysis, familial iNPH-patients had up to 3-fold risk of clinical dementia compared to sporadic iNPH patients. This risk was independent from diagnosed Alzheimer's disease and APOE ε4 genotype. This study describes a familial entity of iNPH offering a novel approach to discover the potential genetic characteristics of iNPH. Discovered pedigrees offer an intriguing opportunity to conduct longitudinal studies targeting potential preclinical signs of iNPH. Copyright © 2016 Elsevier B.V. All rights reserved.

    Because it is a very rare isolated lesion, we decided to present this case of idiopathic pulmonary artery aneurysm (IPAA) and review the cases published in the literature in order to correlate our clinical and imaging findings, as well as management based on patient data. IPAA was first described in a case of autopsy by Bristowe in 1860 and later in 1947 by Deterling and Claggett, whose prevalence was lower than eight to one hundred thousand. Although the use of diagnostic imaging methods has been applied in a very large population in recent decades, this lesion has been most often described in postmortem examinations. Therefore, it is important to be aware of possible clinical symptoms, at times non-specific, as well as the signs on imaging studies. In this study, therefore, the report of a case of an asymptomatic patient whose diagnosis was done through color Doppler echocardiography in a routine test in 2012, later confirmed by simple chest computed tomography (chest CT) and cardiac catheterization as IPAA and its branches. We discussed the literature available and the possibilities for treatment and the use of color Doppler echocardiography as an initial diagnostic tool for such a rare and intriguing disease. (author)

    Full Text Available The detection of any atypical extraoral or intraoral features warrants a thorough investigation, even if the patient is asymptomatic or unaware of these. At times, dental findings help in the diagnosis of an underlying systemic problem. These findings may or may not be associated with any syndrome. Thus, thorough examination and exhaustive investigations should be carried out for every atypical finding to ensure optimal oral and general health for the patient. Case Description: This is a case report of seventeen year old male who presented with peculiar/atypical dentition which ′told the tale′ and led to the diagnosis of underlying endocrinological problem about which the parents were totally unaware. The patient was short with central obesity and microcephaly. Intraorally, there was presence of thirty six microdonts. Consultation with pediatrician and endocrinologist, and thorough investigations confirmed the condition to be of ′Idiopathic Hypergonadotropic Hypogonadism′. The patient underwent not only oral rehabilitation, but also timely consultation and treatment from a pediatrician and an endocrinologist.

    Fistula-in-ano is the most common form of perineal sep- sis. Typically, a fistula includes an internal opening, a track, and an external opening. The external opening might acutely appear following infection and/or an abs-cess, or more insiduously in a chronic manner. Mana-gement includes control of infection, assessment of the fistulous track in relation to the anal sphincter muscle, and finally, definitive treatment of the fistula. Fistulo-tomy was the most commonly used mode of manage-ment, but concerns about post-fistulotomy incontinence prompted the use of sphincter preserving techniques such as advancement flaps, fibrin glue, collagen fistula plug, ligation of the intersphincteric fistula track, and stem cells. Many descriptive and comparative studies have evaluated these different techniques with variable outcomes. The lack of consistent results, level I eviden-ce, or long-term follow-up, as well as the heterogeneity of fistula pathology has prevented a definitive treatment algorithm. This article will review the most commonly available modalities and techniques for managing idio-pathic fistula-in-ano.

    To evaluate the efficacy of zonisamide as a monotherapy in dogs with idiopathic epileptic seizure. The experiment was conducted on 10 dogs with idiopathic epilepsy that were treated at the Seoul National University Hospital for Animals. A diagnosis was conducted based on physical and neurologic examination, complete blood count and chemical analysis, magnetic resonance imaging and cerebrospinal fluid analyses. Idiopathic epilepsy was diagnosed when all of these examinations were normal. Oral zonisamide was administrated to 10 dogs with idiopathic epilepsy at 5-15 mg/kg per os every 12 h to achieve a concentration of zonisamide in serum of 10-40 μg/mL. The frequency of seizures before and after the administration of zonisamide therapy was recorded and the concentrations of zonisamide in serum were measured. Six (60%) of the dogs were favourable responders to treatment, showing a ≥50% reduction in monthly frequency of seizures. Of the remaining four, two dogs did not show a reduction and the other two showed an increase in frequency of seizures. The mean dosage of zonisamide for favourable responders was 7.92 (SD 3.79) mg/kg, which was administered orally twice a day. Only one dog, which was one of the unfavourable responders in the whole study, experienced mild side effects. Among the dogs treated with oral zonisamide, 60% responded favourably. The effect of zonisamide as an anticonvulsant drug was demonstrated in this study. Based on these results, zonisamide monotherapy is effective in some dogs with idiopathic epilepsy.

    Full Text Available Calcinosis cutis is an uncommon disorder characterized by deposition of insoluble calcium salts in the skin. Based on the etiology of the deposition calcinosis cutis may be devided into four major groups namely metastatic, dystrophic, idiopathic, and iatrogenic. The pathophysiology of calcinosis cutis remains unclear. The dystrophic form is the most common whereas the idiopathic one is the rarest. Idiopathic calcinosis cutis occurs in the absence of any identifiable causes and is not associated with drug use. Idiopathic calcinosis cutis has two major types called localized (circumscript and generalized (universalis. Localized type generally involves the vulva, scrotum, penis and breast. A definitive diagnosis requires the histologic demonstration of the accumulation of calcium in the skin and exclusion of other clinic types.There is not an effective treatment for the disease. A 47-year-old woman referred to our outpatient clinic for painless, yellowish-white nodules on her hand enduring for 30 years. A diagnosis of idiopathic calcinosis cutis was made by clinical and histological findings. We present this case because localization of lesions in our case was previously unreported in the literature to our knowledge.

    Hypertrophic scar is one of the unique fibrotic diseases in human. Intraepidermal blister is a common clinical symptom following the hypertrophic scar formation. However, little is known about the reason of blister creation. In this study, we selected three patients with hypertrophic scar as manifested by raised, erythematous, pruritic, blister and thickened appearance undergoing scar resection. The first scar sample was 6 months after burn from the neck of a 3 years old male patient with 10 score by Vancouver Scar Scale (VSS). The second scar sample was 12 months after burn from the dorsal foot of a 16 years old female patient with 13 score by VSS. The third one was 9 months after burn from the elbow of a 34 years old male patients with 13 score by VSS. In order to understand the molecular mechanism of blister formation, we screened the different protein expression between hypertrophic scar and normal skin tissue by means of isobaric tags for relative and absolute quantitation (iTRAQ) labeling technology and high throughput 2D LC-MS/MS. There were 48 proteins found to be downregulated in hypertrophic scar. Among the downregulated ones, plakophilin1 (PKP1), plakophilin3 (PKP3) and desmoplakin (DSP) were the desmosome-related proteins which were validated by immunohistochemistry and western blotting assay. Transmission electron microscopy further showed the considerably reduced size and intensity of hemidesmosome and desmosome in hypertrophic scar tissue, compared to control normal skin. Our data indicted for the first time that downregulation of DSP, PKP1 and PKP3 in hypertrophic scar might be responsible for intraepidermal blister formation. Copyright © 2015 Elsevier Ltd and ISBI.

  7. MicroRNA-21 regulates hTERT via PTEN in hypertrophic scar fibroblasts.

    Directory of Open Access Journals (Sweden)

    Hua-Yu Zhu

    Full Text Available BACKGROUND: As an important oncogenic miRNA, microRNA-21 (miR-21 is associated with various malignant diseases. However, the precise biological function of miR-21 and its molecular mechanism in hypertrophic scar fibroblast cells has not been fully elucidated. METHODOLOGY/PRINCIPAL FINDINGS: Quantitative Real-Time PCR (qRT-PCR analysis revealed significant upregulation of miR-21 in hypertrophic scar fibroblast cells compared with that in normal skin fibroblast cells. The effects of miR-21 were then assessed in MTT and apoptosis assays through in vitro transfection with a miR-21 mimic or inhibitor. Next, PTEN (phosphatase and tensin homologue deleted on chromosome ten was identified as a target gene of miR-21 in hypertrophic scar fibroblast cells. Furthermore, Western-blot and qRT-PCR analyses revealed that miR-21 increased the expression of human telomerase reverse transcriptase (hTERT via the PTEN/PI3K/AKT pathway. Introduction of PTEN cDNA led to a remarkable depletion of hTERT and PI3K/AKT at the protein level as well as inhibition of miR-21-induced proliferation. In addition, Western-blot and qRT-PCR analyses confirmed that hTERT was the downstream target of PTEN. Finally, miR-21 and PTEN RNA expression levels in hypertrophic scar tissue samples were examined. Immunohistochemistry assays revealed an inverse correlation between PTEN and hTERT levels in high miR-21 RNA expressing-hypertrophic scar tissues. CONCLUSIONS/SIGNIFICANCE: These data indicate that miR-21 regulates hTERT expression via the PTEN/PI3K/AKT signaling pathway by directly targeting PTEN, therefore controlling hypertrophic scar fibroblast cell growth. MiR-21 may be a potential novel molecular target for the treatment of hypertrophic scarring.

    Hypertrophic cardiomyopathy (HCM) is a primary disease of the sarcomere, with considerable genetic heterogeneity and variability in phenotypic expression, whose main complication is sudden cardiac death (SCD). Genetic aspects of HCM, its molecular pathophysiology and genotype-phenotype relationships are the subject of this review, which is aimed at better understanding of practical management in this patient population. As HCM is a genetic disease whose initial manifestation can be sudden death, it is essential to establish the diagnosis at an early stage, to proceed with risk stratification and implementation of SCD prevention strategies, and to promote genetic counseling of patients and screening of their families. Detection of pathological mutations through progressive sequencing of the genes most commonly involved is the most efficient way to diagnose HCM, even in the absence of clinical evidence of the disease. Identification of individuals at high risk of SCD is a major challenge in the management of this population, since SCD can be prevented by use of an implantable cardioverter-defibrillator. The selection of patients for prophylactic implantation of these devices, particularly those who have only one major risk factor, is currently the subject of controversy.

    Hypertrophic Cardiomyopathy (HCM) is an inherited heart disease that affects as much as one in 500 individuals, and is the most common cause of sudden death in young athletes. The myocardium becomes abnormally thick in HCM and deforms the internal geometry of the left ventricle (LV). Previous studies have shown that a vortex is formed during diastolic filling, and further that the dilated LV morphology seen in systolic heart failure results in altering the filling vortex from elliptical to spherical shape. We have also previously shown that increasing LV wall stiffness decreases the filling vortex circulation. However, alterations to intraventricular filling fluid dynamics due to an obstructive LV morphology and locally elevated wall stiffness (in the hypertrophied region) have not been previously examined from a mechanistic standpoint. We conducted an experimental study using an idealized HCM physical model and compared the intraventricular flow fields obtained from 2D PIV to a baseline LV physical model with lower wall stiffness and anatomical geometry. The obstruction in the HCM model leads to earlier breakdown of the filling vortex as compared to the anatomical LV. Intraventricular filling in both models under increased heart rates will be discussed.

    Full Text Available BACKGROUND: Hypertrophic cardiomyopathy (HCM is one of the less common forms of primary cardiomyopathies. There is little data available on HCM in Indian literature. AIMS: To assess the incidence and analyse the clinicopathological features of HCM. SETTINGS: Analysis of data of 15 years from a tertiary care centre. METHODS AND MATERIAL: The clinical and pathological data in fourteen cases of HCM with respect to their gross and microscopic features and clinical presentation were reviewed. RESULTS: Incidence of HCM amongst the autopsied primary cardiomyopathies (N = 101 was 13.9% (n=14. Males were affected more. Common presenting symptoms were exertional dyspnoea, angina and palpitations. Concentric and asymmetric hypertrophy was equally seen. Obliterative small vessel disease was noted in 50% of the cases. Although significant myofibre disarray (>5% was seen in all fourteen cases, it could be demonstrated in only 40- 50% of an average of twenty sections studied. Type IA myofibre disarray was the commonest. Six of the fourteen patients died suddenly. Cardiac failure was the commonest cause of death. CONCLUSIONS: Myofibre disarray is a highly sensitive and specific marker for HCM only when considered in a quantitative rather than a qualitative fashion. In this context, the rationale for performing endomyocardial biopsy is to rule out mimics of HCM.

    Nonfamilial cardiomyopathies in childhood have been only sporadically ascribed to endocrine disorders. We report on a 4-month-old male infant presenting with Cushing's syndrome associated with excessive body weight (8.9 kg; >97th percentile) and features of virilization (Tanner stage 2 for pubic hair development). Abdominal sonography showed a large adrenal tumor. Echocardiography revealed myocardial hypertrophy with severe subaortic obstruction. Blood tests showed excessive androgen and cortisol serum levels with absent circadian rhythm as well as suppressed corticotropin. Urine catecholamine levels were within the normal range. Tumor resection with general anesthesia was performed after preparation with antihypertensive and anticongestive drug therapy. Continuous intravenous hydrocortisone substitution was started intraoperatively and subsequently tapered and switched to oral administration after 12 days. A gradual reduction in glucocorticoid substitution and its discontinuation after a total duration of 9 months were well tolerated. Histopathologic workup revealed an adrenocortical tumor of intermediate dignity. Postoperative tumor staging excluded both residual primary tumor and metastases. Both a normalization of body weight and myocardial mass were observed. The present article is, to our knowledge, the first to describe severe hypertrophic obstructive cardiomyopathy caused by an adrenocortical tumor and provides novel detailed data on postoperative glucocorticoid management.

    Christian M Hagen

    Full Text Available Hypertrophic cardiomyopathy (HCM is a genetic cardiac disease primarily caused by mutations in genes coding for sarcomeric proteins. A molecular-genetic etiology can be established in ~60% of cases. Evolutionarily conserved mitochondrial DNA (mtDNA haplogroups are susceptibility factors for HCM. Several polymorphic mtDNA variants are associated with a variety of late-onset degenerative diseases and affect mitochondrial function. We examined the role of private, non-haplogroup associated, mitochondrial variants in the etiology of HCM. In 87 Danish HCM patients, full mtDNA sequencing revealed 446 variants. After elimination of 312 (69.9% non-coding and synonymous variants, a further 109 (24.4% with a global prevalence > 0.1%, three (0.7% haplogroup associated and 19 (2.0% variants with a low predicted in silico likelihood of pathogenicity, three variants: MT-TC: m.5772G>A, MT-TF: m.644A>G, and MT-CYB: m.15024G>A, p.C93Y remained. A detailed analysis of these variants indicated that none of them are likely to cause HCM. In conclusion, private mtDNA mutations are frequent, but they are rarely, if ever, associated with HCM.

    Full Text Available Keloids and hypertrophic scars (HTS are the result of overgrowth of fibrous tissue, following healing of a cutaneous injury, and cause morbidity. There are several treatment modalities which are useful for the management of keloids, though no single modality is completely effective. The most commonly used modalities are pressure, silicone gel sheet, intralesional steroids, 5-fluorouracil (5 FU, cryotherapy, surgical excision, and lasers. They may be used either singly or, as is done more commonly, in combinations. Any qualified dermatologist who has attained postgraduate qualification in dermatology can treat keloids and HTS. Some procedures, such as cryosurgery and surgical excision, may require additional training in dermatologic surgery. Most modalities for keloids, including intralesional injections and mechanical therapies such as pressure and silicone gel based products, can be given/prescribed on OPD basis. Surgical excision requires a minor operation theater with the facility to handle emergencies. It is important to counsel the patient about the nature of the problem. One should realize that keloid will only improve and not disappear completely. Patients should be informed about the high recurrence rates. Different modalities carry risk of adverse effects and complications and the treating physician needs to be aware of these and patients should be informed about them.

    2013-07-01

    Full Text Available Summary: The development of cutaneous pathological scars, namely, hypertrophic scars (HSs and keloids, involves complex pathways, and the exact mechanisms by which they are initiated, evolved, and regulated remain to be fully elucidated. The generally held concepts that keloids and HSs represent “aberrant wound healing” or that they are “characterized by hyalinized collagen bundles” have done little to promote their accurate clinicopathological classification or to stimulate research into the specific causes of these scars and effective preventative therapies. To overcome this barrier, we review here the most recent findings regarding the pathology and pathogenesis of keloids and HSs. The aberrations of HSs and keloids in terms of the inflammation, proliferation, and remodeling phases of the wound healing process are described. In particular, the significant roles that the extracellular matrix and the epidermal and dermal layers of skin play in scar pathogenesis are examined. Finally, the current hypotheses of pathological scar etiology that should be tested by basic and clinical investigators are detailed. Therapies that have been found to be effective are described, including several that evolved directly from the aforementioned etiology hypotheses. A better understanding of pathological scar etiology and manifestations will improve the clinical and histopathological classification and treatment of these important lesions.

    Full Text Available Aim. To study the structure of co-morbidities, especially connective tissue undifferentiated dysplasia syndrome (CTDS, in patients with hypertrophic cardiomyopathy (HCM to develop an algorithm of complex examination of patients.Material and methods. Patients with HCM (n=186; 88 men and 78 women were examined. The diagnosis of HCM was based on current guidelines; molecular genetic study was performed in the absence of phenotypic manifestations. Echocardiography and standard examination of cardiac patient were performed in all patients to identify comorbidities. Genotyping of polymorphisms of 12 modifying genes was performed in 61 patients and 61 people in the control group.Results. HCM was most often associated with uterine myoma (52%, cardiac and extracardiac congenital malformations (50%, and thyroid diseases (37%. Combination of HCM with different variants of connective tissue dysplasia was found in 17% of patients (mitral valve prolapse – 6.3%, tricuspid valve prolapse – 2.7%, supplemental chords – 4.5%, bivalve aortic disease – 1.8%, increased left ventricular trabeculation – 3.6%, atrial septal aneurysm – 3.6%, membranous ventricular septal defect – 1.8%.Conclusion. CTDS is one of the most often associated disorders in patients with HCM. The study of the association of CTDS and HCM, the nature of their genetic structure and similarity of pathogenesis require further study.

    Full Text Available Chondrocytes communicate with each other mainly via diffusible signals rather than direct cell-to-cell contact. The chondrogenic differentiation of mesenchymal stem cells (MSCs is well regulated by the interactions of varieties of growth factors, cytokines, and signaling molecules. A number of critical signaling molecules have been identified to regulate the differentiation of chondrocyte from mesenchymal progenitor cells to their terminal maturation of hypertrophic chondrocytes, including bone morphogenetic proteins (BMPs, SRY-related high-mobility group-box gene 9 (Sox9, parathyroid hormone-related peptide (PTHrP, Indian hedgehog (Ihh, fibroblast growth factor receptor 3 (FGFR3, and β-catenin. Except for these molecules, other factors such as adenosine, O2 tension, and reactive oxygen species (ROS also have a vital role in cartilage formation and chondrocyte maturation. Here, we outlined the complex transcriptional network and the function of key factors in this network that determine and regulate the genetic program of chondrogenesis and chondrocyte differentiation.

    The exercise heart rate (HR) profile and its relation to cardiac function and arrhythmias were investigated in patients with hypertrophic cardiomyopathy (HC). Chronotropic response (CR) and heart rate recovery (HRR) were computed during and after treadmill exercise testing in 273 patients with HC and 95 age-matched healthy controls. Patients with HC had higher prevalence of chronotropic incompetence and lower HRR1-5min compared with controls. Exercise capacity, diastolic function (assessed by E/e') and left atrial volume index were associated with HRR1min and CR in HC. Septal myectomy was associated with reduction in chronotropic incompetence but did not affect HRR1min. In conclusion, impaired CR and HRR1min are associated with advanced disease and do not appear to be independent clinical markers indicating high-risk status in HC. Improving CR by titrating doses of negative chronotropic agents, myectomy, and atrial pacing may be useful to increase exercise capacity in patients with HC. Copyright © 2015 Elsevier Inc.

    Hypertrophic osteoarthropathy (HOA) is a clinico-radiological syndrome characterized by digital clubbing, periosteal proliferation, bone pain, synovitis and arthralgia, all of these being commonly symmetrical. It is occasionally associated with nasopharyngeal lymphoepitheliomas and may develop before or after development of lung metastases in these patients. We report a case of a healthy 22-year-old female who presented to our institution with pain and swelling in the thighs and legs. She had a history of childhood nasopharyngeal lymphoepithelioma. Radiographs of the knees were negative. Magnetic resonance imaging (MRI) showed features suggestive of bilateral periostitis. Because of the propensity of the rare childhood nasopharyngeal lymphoepithelioma to present with HOA, this entity was included in the differential diagnosis. A subsequent chest radiograph and CT demonstrated a lung and mediastinal mass that were histologically confirmed to be metastatic. To the best of our knowledge, HOA and metastases from nasopharyngeal lymphoepithelioma occurring after such a long time interval have not been previously reported. Early demonstration and consideration of HOA on the basis of MRI, lead to expeditious and appropriate subsequent investigation. (orig.)

  6. Metabolism of lipids in experimental hypertrophic hearts of rabbits

    Revis, N.W.; Cameron, A.J.V.

    1979-06-01

    Cardiac hypertrophy was induced in rabbits by subcutaneous injection of thyroxine or isoprenaline or by surgically constricting the abdominal aorta. Alterations in lipid metabolism were observed in these hypertrophic hearts. Thyroxine or isoprenaline treatment increased the fatty acids in the serum and stimulated a marked increase in total lipids, triglycerides, and fatty acids in the hypertrophied myocardium. Coarctation of the aorta, in contrast, induced a significant increase in these lipids without significantly affecting serum free fatty acids. Histochemical and morphological studies confirmed an increase in neutral lipids. It is suggested that the observed increase in fatty acids in the heart following thyroxine or isoprenaline treatment is related to the increase in serum free fatty acids, which is followed by an increase in the removal of serum fatty acids by the heart. However, the amount of serum fatty acids that is removed exceeds the amount that is oxidized, which leads to an increase in lipid stores. The increase in lipid stores in the heart following coarctation of the aorta probably corresponds to the decrease in myocardial concentrations of carnitine. Serum lipid levels following coarctation were not significantly different from those of controls.

  7. Hypertrophic cardiomyopathy: from gene defect to clinical disease

    Institute of Scientific and Technical Information of China (English)

    Major advances have been made over the last decade in our understanding of the molecular basis ofseveral cardiac conditions. Hypertrophic cardiomyopathy (HCM) was the first cardiac disorder in whicha genetic basis was identified and as such, has acted as a paradigm for the study of an inherited cardiacdisorder. HCM can result in clinical symptoms ranging from no symptoms to severe heart failure andpremature sudden death. HCM is the commonest cause of sudden death in those aged less than 35 years,including competitive athletes. At least ten genes have now been identified, defects in which cause HCM.All of these genes encode proteins which comprise the basic contractile unit of the heart, i.e. the sarcomere.While much is now known about which genes cause disease and the various clinical presentations, very littleis known about how these gene defects cause disease, and what factors modify the expression of the mutantgenes. Studies in both cell culture and animal models of HCM are now beginning to shed light on thesignalling pathways involved in HCM, and the role of both environmental and genetic modifying factors.Understanding these mechanisms will ultimately improve our knowledge of the basic biology of heart musclefunction, and will therefore provide new avenues for treating cardiovascular disease in man.

    Idiopathic scoliosis is a three-dimensional deformity of the spine. The most common form is diagnosed in adolescence. While adolescent idiopathic scoliosis (AIS) can progress during growth and cause a surface deformity, it is usually not symptomatic. However, in adulthood, if the final spinal curvature surpasses a certain critical threshold, the risk of health problems and curve progression is increased. To evaluate the efficacy of bracing for adolescents with AIS versus no treatment or other treatments, on quality of life, disability, pulmonary disorders, progression of the curve, and psychological and cosmetic issues. We searched CENTRAL, MEDLINE, EMBASE, five other databases, and two trials registers up to February 2015 for relevant clinical trials. We also checked the reference lists of relevant articles and conducted an extensive handsearch of grey literature. Randomized controlled trials (RCTs) and prospective controlled cohort studies comparing braces with no treatment, other treatment, surgery, and different types of braces for adolescent with AIS. We used standard methodological procedures expected by The Cochrane Collaboration. We included seven studies (662 participants). Five were planned as RCTs and two as prospective controlled trials. One RCT failed completely, another was continued as an observational study, reporting also the results of the participants that had been randomized.There was very low quality evidence from one small RCT (111 participants) that quality of life (QoL) during treatment did not differ significantly between rigid bracing and observation (mean difference (MD) -2.10, 95% confidence interval (CI) -7.69 to 3.49). There was very low quality evidence from a subgroup of 77 adolescents from one prospective cohort study showing that QoL, back pain, psychological, and cosmetic issues did not differ significantly between rigid bracing and observation in the long term (16 years).Results of the secondary outcomes showed that there was low

    Syncope due to idiopathic AV block is characterized by: 1) ECG documentation (usually by means of prolonged ECG monitoring) of paroxysmal complete AV block with one or multiple consecutive pauses, without P-P cycle lengthening or PR interval prolongation, not triggered by atrial or ventricular premature beats nor by rate variations; 2) long history of recurrent syncope without prodromes; 3) absence of cardiac and ECG abnormalities; 4) absence of progression to persistent forms of AV block; 5) efficacy of cardiac pacing therapy. The patients affected by idiopathic AV block have low baseline adenosine plasma level values and show an increased susceptibility to exogenous adenosine. The APL value of the patients with idiopathic AV block is much lower than patients affected by vasovagal syncope who have high adenosine values. Copyright © 2015 Elsevier Inc. All rights reserved.

    1985-03-01

    A study of 130 scoliotic children with curves measuring 10 degrees or more has been performed in order to elucidate the importance of stature, growth and development. Girls with adolescent idiopathic curves measuring 15 degrees or more were taller than girls with smaller idiopathic curves and taller than those whose scoliosis was secondary to leg-length inequality (pelvic tilt scoliosis). No differences were observed as regards growth velocity or development. The increased standing height may be genetic but the uncoiling effect of the normal kyphosis to give a flat lateral profile is a more likely cause. The familial trend in idiopathic scoliosis may therefore be explained by the genetically determined shape of the spine in the median (sagittal) plane.

    Full Text Available The paper describes a clinical case of idiopathic generalized epilepsy with a variable phenotype, a similar type of epileptiform activity in the second stage of sleep, and a similar genotype in siblings. The onset of seizures was observed after closed brain injury in both cases. The sister had myoclonic seizures and her brother had generalized convulsive seizures late in the evening. Idiopathic generalized epilepsy with generalized convulsive seizures appears as generalized tonic-clonic seizures on awakening. But in a number of cases, these seizures may occur when going to sleep. The brother has supposedly idiopathic generalized epilepsy with generalized tonicclonic seizures and his sister has juvenile myoclonic epilepsy, as indicated by her age, hereditary predisposition, phenobarbital-provoked seizures (the latter are also observed in his brother, an electrographic pattern, and the efficacy of Keppra and Topamax.

    Regeneration after spinal cord injury is a serious health issue and there is no treatment for ailing patients. To understand regeneration of the spinal cord we used a system where regeneration occurs naturally, such as the lamprey. In this work, we analyzed the stress response of the spinal cord to tensile loading and obtained the mechanical properties of the cord both in vitro and in vivo. Physiological measurements showed that the spinal cord is pre-stressed to a strain of 10%, and during sinusoidal swimming, there is a local strain of 5% concentrated evenly at the mid-body and caudal sections. We found that the mechanical properties are homogeneous along the body and independent of the meninges. The mechanical behavior of the spinal cord can be characterized by a non-linear viscoelastic model, described by a modulus of 20 KPa for strains up to 15% and a modulus of 0.5 MPa for strains above 15%, in agreement with experimental data. However, this model does not offer a full understanding of the behavior of the spinal cord fibers. Using polymer physics we developed a model that relates the stress response as a function of the number of fibers.

    Non-specific interstitial pneumonia (NSIP) is an interstitial lung disease that may be idiopathic or secondary to connective tissue disease, toxins or numerous other causes. Idiopathic NSIP is a rare diagnosis and requires exclusion of these other possible causes. Patients typically present in mid-adulthood with dyspnoea, cough and often constitutional symptoms including fever and fatigue. The disease has a female predominance, and more than 50% of patients have never smoked. Physical exam features mild hypoxaemia and inspiratory rales. Pulmonary function tests demonstrate restriction and a low diffusing capacity for carbon monoxide. High-resolution computed tomography abnormalities include predominantly lower lobe subpleural reticular changes, traction bronchiectasis and ground-glass opacities; honeycombing is rarely seen. An evaluation of the underlying pathology is necessary for a firm diagnosis. Histologically, alveolar and interstitial mononuclear cell inflammation and fibrosis are seen in a temporally uniform pattern with preserved underlying alveolar architecture. NSIP must be differentiated from other parenchymal lung diseases including idiopathic pulmonary fibrosis and hypersensitivity pneumonitis. A thorough exposure history and assessment for underlying connective tissue diseases are highly important, as positive findings in these categories would likely denote a case of secondary NSIP. A multi-disciplinary discussion that includes pulmonologist(s), radiologist(s) and pathologist(s) assists in reaching a consensus diagnosis and improves diagnostic accuracy. Treatment of idiopathic NSIP, although not well proven, is generally instituted in the form of immunosuppression. Prognosis is favourable compared with idiopathic pulmonary fibrosis, although the diagnosis still carries an attributable mortality. Herein we will summarize the clinical characteristics and management of idiopathic NSIP.

    Patients undergoing posterior spinal instrumentation and fusion surgery for adolescent idiopathic scoliosis were admitted to the intensive care unit until two years ago, at which time we changed our protocol to admit these patients to the general hospital floor following a brief stay in a postanesthesia care unit. This study compared postoperative management on a hospital floor with that in the intensive care unit for patients with adolescent idiopathic scoliosis undergoing posterior spinal fusion. A retrospective review of 124 consecutive patients with adolescent idiopathic scoliosis treated with spinal fusion from August 2007 to August 2010 was performed. Inclusion criteria were a diagnosis of adolescent idiopathic scoliosis and posterior spinal instrumentation and fusion surgery. Of 124 patients, sixty-six were managed postoperatively in the intensive care unit and fifty-eight, on the hospital floor. The mean age at the time of surgery was fourteen years. A mean of eleven vertebral levels (range, six to fifteen levels) were fused. No significant difference between the groups was found with respect to the mean age at the time of surgery, mean weight, mean preoperative and postoperative Cobb angles, and mean number of levels fused (p ≥ 0.12). However, the use of analgesic and antianxiety medication, number of postoperative blood tests, days of hospital stay, and number of physical therapy sessions were significantly decreased in the floor group compared with the intensive care unit group (p ≤ 0.05). No patient from the floor group had to be admitted to the intensive care unit. The mean charge was $33,121 for the floor group and $39,252 for the intensive care unit group (p floor, rather than in an intensive care unit, was associated with a shorter hospital stay, fewer blood tests, less analgesic and antianxiety medication usage, and fewer physical therapy sessions at this high-volume, academic, tertiary-care children's hospital.

    Idiopathic nephrotic syndrome represents the most common type of primary glomerular disease in children: glucocorticoids (GCs) are the first-line therapy, even if considerable interindividual differences in their efficacy and side effects have been reported. Immunosuppressive and anti-inflammatory effects of these drugs are mainly due to the GC-mediated transcription regulation of pro- and anti-inflammatory genes. This mechanism of action is the result of a complex multistep pathway that involves the glucocorticoid receptor and several other proteins, encoded by polymorphic genes. Aim of this review is to highlight the current knowledge on genetic variants that could affect GC response, particularly focusing on children with idiopathic nephrotic syndrome.

    Some patients with dystonic movements and postures not known to be caused by environmental or degenerative disorders can be segregated from classical-appearing idiopathic torsion dystonia on the basis of distinctive clinical and pharmacologic features. Many of them should be considered within the family of dystonia, as clinical variants of idiopathic torsion dystonia, while others are better classified as being part of other families of dyskinesias. In the former group are paradoxical dystonia, myoclonic dystonia, diurnal dystonia, and dopa-responsive dystonia. The latter group consists of dystonic tics and the various entities comprising paroxysmal dystonia, namely kinesigenic, nonkinesigenic and hypnogenic dystonia.

    The term "osteoarthritis" has classically been defined as a low-inflammatory arthritic condition. The term "osteoarthrosis," a synonym for osteoarthritis in the medical orthopedic literature, has recently come to be identified in the dental/temporomandibular joint (TMJ) disorders literature with any noninflammatory arthritic condition that results in similar degenerative changes as in osteoarthritis. The term "idiopathic condylar resorption," also known as "progressive condylar resorption," is described as a dysfunctional remodeling of the TMJ manifested by morphologic change, decreased ramal height, progressive mandibular retrusion in the adult, or decreased mandibular growth in the juvenile. This article discusses the diagnosis and management of osteoarthritic TMJ disorders and idiopathic condylar resorption.

    Introduction. Most spinal-cord-injured patients have constipation. One-third develop chronic abdominal pain 10 years or more after injury. Nevertheless, very little is known about the nature of abdominal pain after spinal cord injury (SCI). It may be neuropathic or caused by constipation. Aim. To compare characteristics of abdominal pain in SCI with able-bodied with chronic idiopathic constipation (CIC). Subjects and Methods. 21 SCI and 15 CIC patients were referred for treatment of bowel symptoms. Constipation-related symptoms were assessed with the Cleveland Constipation Scoring System and the International Spinal Cord Injury Basic Bowel Function Data Set. Characteristics of abdominal pain were described using the Brief Danish Pain Questionnaire. Total gastrointestinal transit times (GITT) were measured by radiopaque markers. Results. Seventeen (81%) SCI and 14 (93%) CIC patients reported abdominal pain or discomfort within the last month (P = 0.38). Pain was considered more intense by CIC than by SCI patients (P GITT. Conclusion. Most characteristics of abdominal pain among SCI patients resemble those of CIC. This indicates that constipation is a major cause of pain after SCI. PMID:24159329

    Hypertrophic cardiomyopathy is caused by mutations in genes encoding sarcomeric proteins. Its variable phenotype suggests the existence of modifier genes. Myocyte enhancer factor (MEF) 2C could be important in this process given its role as transcriptional regulator of several cardiac genes. Any variant affecting MEF2C expression and/or function may impact on hypertrophic cardiomyopathy clinical manifestations. In this candidate gene approach, we screened 209 Caucasian hypertrophic cardiomyopathy patients and 313 healthy controls for genetic variants in MEF2C gene by single-strand conformation polymorphism analysis and direct sequencing. Functional analyses were performed with transient transfections of luciferase reporter constructions. Three new variants in non-coding exon 1 were found both in patients and controls with similar frequencies. One-way ANOVA analyses showed a greater left ventricular outflow tract obstruction (p = 0.011) in patients with 10C+10C genotype of the c.-450C(8_10) variant. Moreover, one patient was heterozygous for two rare variants simultaneously. This patient presented thicker left ventricular wall than her relatives carrying the same sarcomeric mutation. In vitro assays additionally showed a slightly increased transcriptional activity for both rare MEF2C alleles. In conclusion, our data suggest that 15 bp-deletion and C-insertion in the 5'UTR region of MEF2C could affect hypertrophic cardiomyopathy, potentially by affecting expression of MEF2C and therefore, the expression of their target cardiac proteins that are implicated in the hypertrophic process.

    Full Text Available OBJECTIVE: The aim of the present study was to explore the potential for hematoporphyrin monomethyl ether-Sonodynamic Therapy (HMME-SDT treatment of hypertrophic scars within rabbit ears. METHODS: 60 white rabbits were randomly divided into five groups: (1 untreated controls, (2 lesioned, (3 lesioned + HMME, (4 lesioned + US (Ultrasound, and (5 lesioned +HMME-SDT. After induction of a lesion upon the ears of the rabbits, hypertrophic scars were assessed at 14, 28, 42 and 56 days post-lesion +/- treatment. Assessments consisted of visual inspection in the change of the skin, scar formation pathological morphology by hematoxylin and eosin (HE staining technique with optical microscopy, calculation of a hypertrophic index, fibroblastic density measures, and observation of collagen changes in the scar tissue by Van Gieson's (VGStain along with calculation of collagen area density. RESULTS: With continued HMME-SDT treatment there was a gradual improvement in all parameters over the duration of the experiment. The lesion-induced scars of rabbits receiving HMME-SDT treatment were soft, the size was reduced, hyperplasia was flat and the color pale. The fibroblasts and collagens were reduced and the collagens were light red, sparse and orderly. The hypertrophic index was reduced, since the fibroblastic density was lowered and collagen area density was decreased. CONCLUSION: HMME is an effective sonosensitizer and the combination of HMME-SDT treatment can exert significant benefits in reducing the formation of hypertrophic scars.

    Fixed subaortic stenosis is considered to be an acquired condition. It is often associated with congenital heart disease, creating a turbulence in the left ventricle outflow tract. Familial forms of fixed subaortic stenosis are very unusual. We report a remarkable familial cluster in which fixed subaortic stenosis is associated with hypertrophic cardiomyopathy. Fourteen relatives of a patient affected with hypertrophic cardiomyopathy and fixed subaortic stenosis underwent cardiological examination, electrocardiogram and echo-doppler study. Two of the proband's sisters showed an association between asymmetrical hypertrophic cardiomyopathy and fixed subaortic stenosis. The brother presented a subaortic ridge and concentric left ventricular hypertrophy. The other members of the family (another brother and the third-generation relatives) were unaffected. While the association between fixed subaortic stenosis and hypertrophic cardiomyopathy has commonly been reported, there is little in the literature to suggest the family-related nature of this association. The familial occurrence of this association reveals genetic transmission, with a recessive autosomal pattern of inheritance. This finding goes against the usual autosomal dominant pattern of inheritance in hypertrophic cardiomyopathy. Familial studies of FSS are needed in order to gain a better understanding of the genetic background of these patients.

    Pressure overload induces hypertrophic growth of the heart and in the long term this condition can lead to cardiomyopathy and heart failure. Several miRNAs are upregulated in heart failure. However, it is not clear, which miRNAs (if any) are induced during the early hypertrophic growth phase...... was highly induced in animals with aortic banding. Out of 13 miRs that have previously been reported to be associated with late-stage pressure-overload-induced hypertrophy and heart failure only four (miR-23a, miR-27b, miR-125b and miR-195) were induced during early hypertrophic growth. These miRs were....... To investigate whether the upregulation of miRNAs is an integrated part of hypertrophic growth or an effect of cardiac disease we investigated miRNA expression in early hypertrophic development. Hypertrophy was induced by banding of the ascending aorta of male rats. After 14 days, the heart left ventricle weight...

    Full Text Available Hypertrophic scarring is a common proliferative disorder of dermal fibroblasts characterized by collagen overproduction and excessive deposition of extracellular matrix (ECM. There is no consensus about the best therapeutics to produce complete and permanent improvement of scars with few side effects. To investigate the therapeutic effects of oleanolic acid (OA on hypertrophic scars and explore the possible mechanism of action involved, a rabbit ear model with hypertrophic scars was established. OA (2.5%, 5%, and 10% was given once daily to the scars for 28 consecutive days. As a result, OA significantly alleviated formed hypertrophic scars on rabbit ears. The levels of TGF-β1, MMP-1, TIMP-1, and collagens I and III were notably decreased, and the number of apoptosis cells and mRNA expression of MMP-2, caspase-3, and caspase-9 were markedly increased in the scar tissue. The scar elevation index (SEI was also evidently reduced. Histological findings exhibited significant amelioration of the collagen tissue. These results suggest that OA has the favorable curative effects on formed hypertrophic scars in the rabbit ear model, and the possible mechanism of action is that OA decreases HSFs proliferation and increases HSFs apoptosis by reduction of P311 gene expression and TGF-β1 production, inhibition of TIMP-1 secretion, enhancement of MMP-2 activity, and subsequently facilitation of degradation of collagen types I and III.

    Objective To determine the clinical application of pulsed Doppler tissue imaging in assessing the left ventricular diastolic function and in discriminating between normal subjects and patients with hypertrophic cardiomyopathy with various stages of diastolic dysfunction.Methods We measured the peak diastolic velocities of mitral annulus in 81 patients with hypertrophic cardiomyopathy with various stages of diastolic dysfunction and 50 normal volunteers by Doppler tissue imaging using the apical window at 2-chamber and long apical views, respectively. The myocardial velocities were determined with use of variance F statistical analysis.Results Early diastolic myocardial velocities ofmitral annulus were higher in normal subjects than in patients with hypertrophic cardiomyopathy with either delayed relaxation, pseudonormal filling, or restrictive filling. However, peak myocardial velocities of mitral annulus during atrial contraction were similar in normal subjects and patients with hypertrophic cardiomyopathy.Conclusion Doppler tissue imaging can directly reflect upon left diastolic ventricular function. Early phase of diastole was the best discriminator between control subjects and patients with hypertrophic cardiomyopathy.

    The value of tissue strain imaging (SI) in regional myocardial systolic anddiastolic function assessment was studied. In 18 patients with nonobstructive hypertrophic cardiomyopathy (HCM) and 20 age-matched healthy subjects, regional myocardial longitudinal peak systolic strain in eject time (represented by εet) was measured at basal, mid and apical segments of septal, lateral and posterior walls of the left ventricle (LV) and compared between groups. εet had no significant difference between segments in control group (P>0.05), which displayed a decreasing trend from basal segments to apical ones. εet in the HCM group was significantly decreased (P<0. 05) as compared with that in the healthy group. In the HCM group, εet in the midseptum was significantly less than at the basal and apical septum, and was also less than at the rest LV walls in the same group (P<0.01). The systolic reversed εet was noticed in 35 % of the hypertrophic segments in HCM group. Significantly negative correlation existed between the absolute value of εet and wall thickness in the midseptum (r=- 0.83). The post-systolic strain(PSS) segment number the and amplitudes in healthy group were significantly less than those in HCM group (P<0.05). Both regional myocardial systolic and diastolic functions were impaired in hypertrophic or non-hypertrophic segments in patients with the HCM, especially in hypertrophic segments. Strain imaging technique is a sensitive and accura tool in myocardial dysfunction assessment.

    Congenital spinal malformations form a complex and heterogeneous group of disorders whose pathogenesis is best explained embryologically. Radiologically, it is important to formulate a diagnosis when the disorder first becomes symptomatic. However, it is also crucial to detect complications of the disorder or of the respective therapeutic interventions in the further course of the disease such as hydromyelia or re-tethering after repair of a meningomyelocele. Moreover, once a congenital spinal malformation is diagnosed, associated malformations should be sought after. A possible syndromal classification such as in OEIS- or VACTERL-syndromes should also be considered. (orig.) [German] Kongenitale spinale Malformationen stellen eine komplexe Gruppe an Stoerungen dar, deren Genese sich am einfachsten aus der Embryologie heraus erklaeren laesst. Bei der klinisch-radiologischen Begutachtung ist zunaechst ihre korrekte Klassifikation im Rahmen der Erstdiagnose wichtig. Im weiteren Verlauf ist es jedoch zudem entscheidend, moegliche Komplikationen wie beispielsweise eine Hydromyelie oder ein Wiederanheften des Myelons nach Operation einer Spina bifida aperta zu erkennen. Zudem sollte bei der Diagnosestellung einer kongenitalen spinalen Malformation immer auch auf assoziierte Fehlbildungen, wie z.B. die Diastematomyelie oder das intraspinale Lipom bei der Spina bifida aperta, sowie auf eine moegliche syndromale Einordnung wie beispielsweise beim OEIS-oder VACTERL-Syndrom geachtet werden.

    Because it may cause paralysis, injury to the spine is one of the most feared traumas, and spinal cord injury is a major cause of disability. In the USA approximately 10,000 traumatic cervical spine fractures and 4000 traumatic thoracolumbar fractures are diagnosed each year. Although the number of individuals sustaining paralysis is far less than those with moderate or severe brain injury, the socioeconomic costs are significant. Since most of the spinal trauma patients survive their injuries, almost one out of 1000 inhabitants in the USA are currently being cared for partial or complete paralysis. Little controversy exists regarding the need for accurate and emergent imaging assessment of the traumatized spine in order to evaluate spinal stability and integrity of neural elements. Because clinicians fear missing occult spine injuries, they obtain radiographs for nearly all patients who present with blunt trauma. We are influenced on one side by fear of litigation and the possible devastating medical, psychologic and financial consequences of cervical spine injury, and on the other side by pressure to reduce health care costs. A set of clinical and/or anamnestic criteria, however, can be very useful in identifying patients who have an extremely low probability of injury and who consequently have no need for imaging studies. Multidetector (or multislice) computed tomography (MDCT) is the preferred primary imaging modality in blunt spinal trauma patients who do need imaging. Not only is CT more accurate in diagnosing spinal injury, it also reduces imaging time and patient manipulation. Evidence-based research has established that MDCT improves patient outcome and saves money in comparison to plain film. This review discusses the use, advantages and disadvantages of the different imaging techniques used in spinal trauma patients and the criteria used in selecting patients who do not need imaging. Finally an overview of different types of spinal injuries is given

    Measurements obtained in 50 spinal CT studies of patients referred for suspected lumbosacral nerve root compression, were compared to those of a group of 30 individuals asymptomatic in this respect, who had been referred for abdominal pathology. Transverse ligamentous interfacet and transverse dural dimensions were significantly reduced in the sciatica group, with usually normal interpedicular and sagittal dimensions ruling out idiopathic developmental stenosis. The borderline value for ligamentous interfacet distance (ILD) at L4-5 appeared to be 11 mm.

    Full Text Available Background: End-stage hypertrophic cardiomyopathy (HCM is complicated by substantial adverse events. However, few studies have focused on electrocardiographic features and their prognostic values in HCM. This study aimed to evaluate the clinical manifestations and prognostic value of electrocardiography in patients with end-stage HCM. Methods: End-stage HCM patients were enrolled from a total of 1844 consecutive HCM patients from April 2002 to November 2013 at Fuwai Hospital. Clinical data, including medical history, electrocardiography, and echocardiography, were analyzed. Cox hazards regression analysis was used to assess the risk factors for cardiovascular mortality. Results: End-stage HCM was identified in 99 (5.4% patients, averaged at 52 ± 16 years old at entry. Atrial fibrillation was observed in 53 patients and mural thrombus in 19 patients. During 3.9 ± 3.0 years of follow-up, embolic stroke, refractory heart failure, and death or transplantation were observed in 20, 39, and 51 patients, respectively. The incidence of annual mortality was 13.2%. Multivariate Cox hazards regression analysis identified New York Heart Association Class (NYHA III/IV at entry (hazard ratio [HR]: 1.99; 95% confidence interval [CI]: 1.05-3.80; P = 0.036, left bundle branch block (LBBB (HR: 2.80; 95% CI: 1.47-5.31; P = 0.002, and an abnormal Q wave (HR: 2.21; 95% CI: 1.16-4.23; P = 0.016 as independent predictors of cardiovascular death, in accordance with all-cause death and heart failure-related death. Conclusions: LBBB and an abnormal Q wave are risk factors of cardiovascular mortality in end-stage HCM and provide new evidence for early intervention. Susceptibility of end-stage HCM patients to mural thrombus and embolic events warrants further attention.

    In abnormal skin wound healing, hypertrophic scars (HS) are characterized by excessive fibroblast hypercellularity and an overproduction of collagen, leading to atypical extracellular matrix (ECM) remodeling. Although the exact mechanisms of HS remain unclear, decreased HS fibroblast (HSFB) apoptosis and increased proliferation are evident in the development of HS. In this study, the contribution of the second mitochondria-derived activator of caspases/direct inhibitor of apoptosis protein (IAP)-binding protein with a low isoelectric point (pI) (Smac/DIABLO), an apoptosis-promoting protein released from the mitochondria, was investigated in human normal skin and HSFB cultures. The expression of Smac/DIABLO is usually decreased in many malignant tumors compared with normal tissues. Immunohistochemical analysis of skin tissues and the western blot analyses of fibroblasts revealed that the expression of Smac/DIABLO was lower in HS tissues compared with normal skin tissues. Of note, adenovirus-mediated Smac/DIABLO overexpression in the cultured HSFBs significantly reduced cell proliferation, as detected by the cell counting kit-8, and increased caspase-3 and -9 activity, as detected by spectrofluorimetry. In addition, it increased apoptosis, as detected by fluorescence-activated cell sorting (FACS). Furthermore, we found that the silencing of Smac with siRNA in the HSFBs induced a noticeable decrease in caspase-3 and -9 activity, leading to a significant reduction in apoptosis. In addition, the mRNA expression of type I and III pro-collagen detected in the HSFBs was significantly increased following the silencing of Smac with siRNA and was inhibited following Smac/DIABLO overexpression, as shown by real-time RT-PCR. In conclusion, Smac/DIABLO decreases the proliferation and increases the apoptosis of HSFBs. To our knowledge, the data from our study suggest for the first time that Smac/DIABLO is a novel therapeutic target for HS.

    Social determinants of health play an important role in explaining poor health outcomes across many chronic disease states. The impact of the social gradient in the setting of an inherited heart disease, hypertrophic cardiomyopathy (HCM), has not been investigated. This study sought to profile the socioeconomic status of patients attending a specialized multidisciplinary clinic and to determine the impact on clinical factors, psychosocial wellbeing and adherence to medical advice. Patients with HCM and at-risk relatives attending a specialized multidisciplinary clinic in Sydney Australia between 2011 and 2013 were included. Clinical, socioeconomic, geographic remoteness and adherence data were available. A broader clinic and registry-based group completed a survey including psychological wellbeing, health-related quality of life, Morisky Medication Adherence Scale and individual-level socioeconomic information. Over a 3-year period, 486 patients were seen in the specialized clinic. There was an over-representation of patients from socioeconomically advantaged and the least geographically remote areas. Socioeconomic disadvantage was associated with comorbidities, poor psychological wellbeing and health-related quality of life, lower understanding of HCM and more complex clinical management issues such as NYHA class, atrial fibrillation and left ventricular outflow tract obstruction. Approximately 10% of patients were non-adherent to medical advice, and poor medication adherence was seen in 30% of HCM patients with associated factors being younger age, minority ethnicity, anxiety and poor mental quality of life. Of all the patients attending a specialized cardiac genetic clinic, there is an overrepresentation of patients from very advantaged and major metropolitan areas and suggests that those most in need of a multidisciplinary approach to care are not accessing it.

    Yield of causative variants in hypertrophic cardiomyopathy (HCM) is increased in some probands, suggesting different clinical subgroups of disease occur. We hypothesized that a negative family history and no sarcomere mutations represent a nonfamilial subgroup of HCM. We sought to determine the prevalence, natural history, and potential clinical implications of this nonfamilial subgroup of HCM. Four hundred and thirteen unrelated probands with HCM seen in a specialized HCM center between 2002 and 2015 and genetic testing performed were included in this retrospective cohort study. There were 251 (61%) probands with no reported family history of HCM, including 166 (40% of total) probands with no sarcomere mutation, that is, nonfamilial HCM. Quantified family pedigree data revealed no difference in mean number of first-degree relatives screened between nonfamilial and sarcomere-positive groups. Adjusted predictors of nonfamilial status were older age (odds ratio, 1.04; 95% confidence interval, 1.02-1.06; P=0.0001), male sex (odds ratio, 1.96; 95% confidence interval, 1.11-3.45; P=0.02), hypertension (odds ratio, 2.80; 95% confidence interval, 1.57-5.00; P=0.0005), and nonasymmetric septal morphology (odds ratio, 3.41; 95% confidence interval, 1.64-7.08; P=0.001). They had a less severe clinical course with greater event-free survival from major cardiac events (P=0.04) compared with sarcomere-positive HCM probands. Genotype prediction scores showed good performance in identifying genotype-positive patients (area under the curve, 0.71-0.75) and, in combination with pedigree characteristics, were further improved. Approximately 40% of HCM probands have a nonfamilial subtype, with later onset and less severe clinical course. We propose a revised clinical pathway for management, highlighting the role of genetic testing, a detailed pedigree, and refined clinical surveillance recommendations for family members. © 2017 American Heart Association, Inc.

    The aim of this study was to compare three methods of postoperative feeding after pyloromyotomy for hypertrophic pyloric stenosis (HPS). The authors reviewed retrospectively the charts of 308 patients who underwent pyloromyotomy for HPS from 1984 to 1997. Nineteen patients had prolonged hospitalization for other reasons and were excluded from the study, leaving 289 patients for analysis. All procedures were performed by a single group of pediatric surgeons. The individual preferences of these surgeons resulted in three different feeding schedules: R, strictly regimented (>12 hours nothing by mouth, then incremental feeding over > or =24 hours), I, intermediate (>8 hours nothing by mouth, then incremental feeding over lib (lib feedings). Of the 289 patients, 248 (80.5%) were boys. The average age of the patients was 5.64 weeks (range, 1 to 21 weeks). A total of 265 of 289 (92%) were full term. Thirty-nine of 289 (13.5%) had a family history positive for pyloric stenosis. A total of 104 of 289 (36%) were first-born infants, 89 of 289 (31%) were second born. The diagnosis of pyloric stenosis was made by a combination of physical examination findings and diagnostic image for most patients. An "olive" was palpated in 60.6% of the patients. Sixty percent (60.4%) of patients had an upper gastrointestinal series performed, and 42.5% were examined by ultrasonography. Overall, 53% of the patients had postoperative emesis. Only 3.5% had emesis that persisted greater than 48 hours after surgery. Patients fed ad lib after pyloromyotomy had slightly more emesis (2.2 A v. 1.2 R, and 0.7 I episodes, P = .002), but tolerated full feedings sooner than patients fed with a regimented or intermediate schedule. No patient required additional therapy or readmission after tolerating two consecutive full feedings, suggesting that this might be a suitable discharge criterion for most patients with HPS.

  18. Biventricular / Left Ventricular Pacing in Hypertrophic Obstructive Cardiomyopathy: An Overview

    Directory of Open Access Journals (Sweden)

    Radu Vatasescu, MD

    2012-05-01

    Full Text Available Hypertrophic cardiomyopathy (HCM is an autosomal dominant inherited genetic disease characterized by compensatory pathological left ventricle (LV hypertrophy due to sarcomere dysfunction. In an important proportion of patients with HCM, the site and extent of cardiac hypertrophy results in severe obstruction to LV outflow tract (LVOT, contributing to disabling symptoms and increasing the risk of sudden cardiac death (SCD. In patients with progressive and/or refractory symptoms despite optimal pharmacological treatment, invasive therapies that diminish or abolish LVOT obstruction relieve heart failure-related symptoms, improve quality of life and could be associated with long-term survival similar to that observed in the general population. The gold standard in this respect is surgical septal myectomy, which might be supplementary associated with a reduction in SCD. Percutaneous techniques, particularly alcohol septal ablation (ASA and more recently radiofrequency (RF septal ablation, can achieve LVOT gradient reduction and symptomatic benefit in a large proportion of HOCM patients at the cost of a supposedly limited septal myocardial necrosis and a 10-20% risk of chronic atrioventricular block. After an initial period of enthusiasm, standard DDD pacing failed to show in randomized trials significant LVOT gradient reductions and objective improvement in exercise capacity. However, case reports and recent small pilot studies suggested that atrial synchronous LV or biventricular (biV pacing significantly reduce LVOT obstruction and improve symptoms (acutely as well as long-term in a large proportion of severely symptomatic HOCM patients not suitable to other gradient reduction therapies. Moreover, biV/LV pacing in HOCM seems to be associated with significant LV reverse remodelling.

    Research into the pathophysiology and treatment of hypertrophic scar (HSc) remains limited by the heterogeneity of scar and the imprecision with which its severity is measured. The objective of this study was to test the interrater reliability and concurrent validity of the Cutometer measurement of elasticity, the Mexameter measurement of erythema and pigmentation, and total thickness measure of the DermaScan C relative to the modified Vancouver Scar Scale (mVSS) in patient-matched normal skin, normal scar, and HSc. Three independent investigators evaluated 128 sites (severe HSc, moderate or mild HSc, donor site, and normal skin) on 32 burn survivors using all of the above measurement tools. The intraclass correlation coefficient, which was used to measure interrater reliability, reflects the inherent amount of error in the measure and is considered acceptable when it is >0.75. Interrater reliability of the totals of the height, pliability, and vascularity subscales of the mVSS fell below the acceptable limit ( congruent with0.50). The individual subscales of the mVSS fell well below the acceptable level (0.89) for each study site with the exception of severe scar. Mexameter and DermaScan C reliability measurements were acceptable for all sites (>0.82). Concurrent validity correlations with the mVSS were significant except for the comparison of the mVSS pliability subscale and the Cutometer maximum deformation measure comparison in severe scar. In conclusion, the Mexameter and DermaScan C measurements of scar color and thickness of all sites, as well as the Cutometer measurement of elasticity in all but the most severe scars shows high interrater reliability. Their significant concurrent validity with the mVSS confirms that these tools are measuring the same traits as the mVSS, and in a more objective way.

    Objectives To investigate the clinical manifestations of hypertrophic cardiomyopathy (HCM), and to find out the clinical clues to avoid misdiagnosis and provide reference for future clinical diagnosis and treatment. Methods A retrospective analysis of 42 consecutive patients with HCM hospitalized in our hospital between January 1995 and December 2002 was explored. Based on the family history of HCM, clinical manifestations, electrocardiogram, echocardiogram, coronary angiography and left ventriculography, the clinical characteristics between HCM patients with left ventricular outflow tract obstruction (HOCM) and HCM patients without obstruction (HNOCM) were compared. The causes of misdiagnosis and losing diagnosis were analysis.Results 13 patients were in HOCM group and 29 patients were in HNOCM group. More patients with syncope were in HOCM group than in HNOCM group (6/13 vs. 2/29, P < 0.05). Patients with ejective murmur were in HOCM group only (P < 0.01). Left ventricular outflow tract pressure gradient (LVOTPG)only observed in HOCM group (P<0.01). Ventricular tachycardia was seen in both groups. 28 out of 42 patients (66.67%) had misdiagnosis, and 4 out of 42 patients (9.53%) had losing diagnosis. Thus, coronary heart disease (CHD) had the highest rate of misdiagnosis. There were 20 CHD patients (71.43%)among 28 patients with misdiagnosis. Hypertension was in 3, congenital heart in 2, cerebro-embolism in 2, and myocarditis in 1. Conclusions For a patient with family history or sudden death history of HCM,unexplained syncope episodes, chest pain (angina),especially in young, an ejection murmur along the left sternum border, the presence of narrow and deep Q waves, or inversion of giant T waves in V3-V6, atrial fibrillation and /or cerebra-embolism echocardiogram should be given. CAG and LVG are necessary only if the result of echo is negative, and the patients with suspected HCM or CHD.

    Hypertrophic pachymeningitis (HP) is an important neurologic complication of granulomatosis with polyangiitis (GPA, formerly Wegener's granulomatosis). The aim of this study is to investigate the clinical features, radiological findings, and diagnostic pitfalls of GPA-related HP. A retrospective chart review was performed to screen patients diagnosed with GPA at Samsung Medical Center between 1997 and 2016. Neurologic manifestation, laboratory findings, neuroimaging data, and clinical course were evaluated in all patients. Characteristics of patients with HP were compared to those of patients without HP. Sixty-five patients with GPA were identified. Twenty-five of these patients had central nervous system involvement. HP (N = 9, 36%) was the second most common radiologic finding. Other neurologic findings included stroke (N = 7, 28%) and granulomatous disease (N = 10, 40%). Patients with HP had lower incidences of systemic manifestations (N = 2, 22.2% vs. N = 38, 67.9%, p = 0.013 in the lung and N = 1, 11.1% vs. N = 28, 50.0%, p = 0.030 in the kidney) than those without HP. Six patients with GPA-related HP were MPO-ANCA positive (66.7%) and two had PR3-ANCA (22.2%). Most of the patients with HP presented with headache (N = 8, 88.9%) at a rate that is similar to those of primary headache disorders (migraine, tension-type, and stabbing) and other secondary headache disorders (postural type and meningitis). Patients with HP rarely had neurologic deficits (N = 3, 37.5%). Different clinical or radiologic features may be observed in GPA-related HP. Early recognition and accurate diagnosis of GPA-related HP are needed in addition to neuroimaging findings.

    Myomesin plays an important structural and functional role in the M-band of striated muscles. The C-terminal domain 13 of myomesin dimerises and forms antiparallel strands which cross-link neighboring Myosin filaments and titin in the M-line of the sarcomeres. These interactions stabilise the contractile apparatus during striated muscle contraction. Since myomesin is an important component of the M-band we screened the myomesin gene for genetic variants in patients with hypertrophic cardiomyopathy (HCM). We identified the missense mutation V1490I in domain 12 of myomesin in a family with inherited HCM. Analytical ultracentrifugation experiments, circular dichroism spectra, and surface plasmon resonance spectroscopy of myomesin fragments were carried out to investigate the effects of the mutation V1490I on structure and function of myomesin domains 11-13 and 12-13. Both the wild type and mutated myomesin domains My11-13 revealed similar secondary structures and formed stable dimers. Mutated myomesin domains My11-13 and My12-13 dimers revealed a reduced thermal stability and a significantly decreased dimerisation affinity, showing disturbed functional properties of V1490I mutated myomesin. However, monomeric myomesin domains My11-12, i.e. without dimerisation domain 13 showed no difference in thermal stability between wild type and V1490I mutated myomesin. In conclusion, the V1490I mutation associated with HCM lead to myomesin proteins with abnormal functional properties which affect dimerisation properties of myomesin domain 13. These effects may contribute to the pathogenesis of HCM. Copyright © 2011 Elsevier Inc. All rights reserved.

  3. A Murine Hypertrophic Cardiomyopathy Model: The DBA/2J Strain.

    Directory of Open Access Journals (Sweden)

    Wenyuan Zhao

    Full Text Available Familial hypertrophic cardiomyopathy (HCM is attributed to mutations in genes that encode for the sarcomere proteins, especially Mybpc3 and Myh7. Genotype-phenotype correlation studies show significant variability in HCM phenotypes among affected individuals with identical causal mutations. Morphological changes and clinical expression of HCM are the result of interactions with modifier genes. With the exceptions of angiotensin converting enzyme, these modifiers have not been identified. Although mouse models have been used to investigate the genetics of many complex diseases, natural murine models for HCM are still lacking. In this study we show that the DBA/2J (D2 strain of mouse has sequence variants in Mybpc3 and Myh7, relative to widely used C57BL/6J (B6 reference strain and the key features of human HCM. Four-month-old of male D2 mice exhibit hallmarks of HCM including increased heart weight and cardiomyocyte size relative to B6 mice, as well as elevated markers for cardiac hypertrophy including β-myosin heavy chain (MHC, atrial natriuretic peptide (ANP, brain natriuretic peptide (BNP, and skeletal muscle alpha actin (α1-actin. Furthermore, cardiac interstitial fibrosis, another feature of HCM, is also evident in the D2 strain, and is accompanied by up-regulation of type I collagen and α-smooth muscle actin (SMA-markers of fibrosis. Of great interest, blood pressure and cardiac function are within the normal range in the D2 strain, demonstrating that cardiac hypertrophy and fibrosis are not secondary to hypertension, myocardial infarction, or heart failure. Because D2 and B6 strains have been used to generate a large family of recombinant inbred strains, the BXD cohort, the D2 model can be effectively exploited for in-depth genetic analysis of HCM susceptibility and modifier screens.

    Objective:Several studies have analyzed the clinical profiles of patients diagnosed with hypertrophic cardiomyopathy(HCM). We sought to identify its characteristics in a regional cohort of Nanjing and its adjacent region. Methods:Clinical profiles of 121 referred patients were collected and analyzed retrospectively. Data including family history, clinical symptoms, electrocardiography and recent echocardiography were collected. Results: The mean age of this population was 42±17 years(range from 6 to 76) at diagnosis of HCM. Most patients were male(60%). 48 patients(39.7%) has a family history, 19 had a sudden death in a first degree relative and 96(792,%) were recognized with cardiac symptoms. Left ventricular outflow obstruction (gradient≥30 mmHg at rest) was presented in 26(21.5%) patients. ECG abnormalities comprised of arrhythmia in 54(51.4%) and abnormal T wave in 72(68.6%) patients. FS were higher in female than male(P=0.001). Among younger patients(age ≤ 50 years), LVDd and LVWP were smaller in females than males(P=0.042 & 0.023 respectvely). In older patients(age > 50 years), LVDs was higher in male(P= 0.016) and EF was higher in female (P=0.048). Conclusion:HCM patients in the region are almost diagnosed with the presentation of cardiac symptoms; those without any symptoms could be recognized by ECG and family screening. Most cardiac hypertrophy affects the interventricular septum. LVDd, LVWP, LVDs, FS and EF showed significant differences related to age and gender.

    An insertion/deletion (I/D) polymorphism of the angiotensin I converting enzyme (ACE) gene is a useful predictor of human plasma ACE levels. ACE levels tend to be lowest in subjects with ACE genotype DD and intermediate in subjects with ACE genotype ID. Angiotensin II (Ang II) as a product of ACE is a cardiac growth factor and produces a marked hypertrophy of the chick myocyte in cell culture. Rat experiments also suggest that a small dose of ACE inhibitor that does not affect the afterload results in prevention or regression of cardiac hypertrophy. In order to study the relationship of ACE and the severity of hypertrophy, the ACE genotype has been determined in 28 patients with a clinical diagnosis of familial hypertrophic cardiomyopathy (FHC) and 51 normal subjects. The respective frequencies of I and D alleles were: 0.52 and 0.48 (in FHC patients) and 0.44 and 0.56 (in the normal controls). There was no significant difference in the allele frequencies between FHC and normal subjects ({chi}{sup 2}=0.023, p>0.05). The II, ID, and DD genotypes were present in 7, 15, and 6 FHC patients, respectively. The averages of maximal thickness of the interventricular septum measured by echocardiography or at autopsy were 18 {plus_minus}3, 19{plus_minus}4, and 19{plus_minus}3 mm in II, ID and DD genotypes, respectively. The ACE gene polymorphism did not correlate with the severity of left ventricular hypertrophy in FHC patients (r{sub s}=0.231, p>0.05). These results do not necessarily exclude the possible effect of Ang II on the hypertrophy since the latter may be produced through the action of chymase in the human ventricles. However, ACE gene polymorphism is not a useful predictor of the severity of myocardial hypertrophy in FHC patients.

    This study aims at investigating the efficiency of bimodal spectroscopy in detection of hypertrophic scar tissue on a preclinical model. Fluorescence and Diffuse Reflectance spectra were collected from 55 scars deliberately created on ears of 20 rabbits, amongst which some received tacrolimus injection to provide non-hypertrophic scar tissue. The spectroscopic data measured on hypertrophic and non-hypertrophic scar tissues were used for developing our classification algorithm. Spectral features were extracted from corrected data and analyzed to classify the scar tissues into hypertrophic or non-hypertrophic. The Algorithm was developed using k-NN classifier and validated by comparing to histological classification result with Leave-One-Out cross validation. Bimodal spectroscopy showed promising results in detecting hypertrophic tissue (sensibility 90.5%, specificity 94.4%). The features used for classification were extracted from the autofluorescence spectra collected at 4 CEFS with excitations at 360, 410, and 420 nm. This indicates the hypertrophic process may involve change in concentration of several fluorophores (collagen, elastin and NADH) excited in this range, or modification in volume of explored tissue layers (epidermis and dermis) due to tissue thickening.

    Radiofrequency ablation (RFA) has been shown to be very effective in the treatment of supraventricular tachycardias and has replaced surgical ablation. Only a few reports of RFA for idiopathic ventricular tachycardia (VT) have appeared in the literature during the last two years. This paper presents our experience with RFA for idiopathic VT in 19 patients. In all patients the diagnostic study and therapeutic RFA were combined in a single procedure. Pacemapping were used to guide the site of RFA in patients with VT arising from the RV. Local activation time (LAT), Purkinje potentials (PP) and pacemapping were used to guide RFA in those patients with LV septal tachycardias. Idiopathic VT frequently arises from the RVOT and inferobasal portion of the LV septum. These tachycardias can be diagnosed on clinical and ECG grounds. RFA for idiopathic VT arising from these areas has a high success rate and this mode of treatment should be considered as a nonpharmacological curative treatment for symptomatic patients. 13 refs., 3 tabs., 4 figs.

    Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in childhood. The pathogenesis of JIA is thought to be the result of a combination of host genetic and environmental triggers. However, the precise factors that determine one's susceptibility to JIA remain to be unravelled. The
