AIM: To compare the difference of expression of Bcl-2 and Bax in extrahepatic biliary tract carcinoma and dysplasia, and to analyze the role of Bcl-2 and Bax proteins in the progression from dysplasia to carcinoma and to evaluate the correlation of Bcl-2/Bax protein expression with the biological behaviors. METHODS: Expressions of Bcl-2 and Bax were examined immunohistochemically in 27 cases of extrahepatic biliary tract carcinomas (bile duct carcinoma: n = 21, carcinoma of ampulla of Vater: n = 6), and 10 cases of atypical dysplasia. Five cases of normal biliary epithelial tissues were used as controls. A semiquantitative scoring system was used to assess the Bcl-2 and Bax reactivity. RESULTS: The expression of Bcl-2 was observed in 10 out of 27 (37.0%) invasive carcinomas, 1 out of 10 dysplasias, none out of 5 normal epithelial tissues. Bax expression rate was 74.1% (20/27) in invasive carcinoma, 30% (3/10) in dysplasia, and 40% (2/5) in normal biliary epithelium. Bcl-2 and Bax activities were more intense in carcinoma than in dysplasia, with no significant difference in Bcl-2 expression (P = 0.110), and significant difference in Bax expression (P = 0.038). Level of Bax expression was higher in invasive carcinoma than in dysplasia and normal tissue (P = 0.012). Bcl-2 expression was correlated to Bax expression (P = 0.0059). However, Bcl-2/Bax expression had no correlation with histological subtype, grade of differentiation, or level of invasion. CONCLUSION: Increased Bcl-2/Bax expression from dysplasia to invasive tumors supports the view that this is the usual route for the development of extrahepatic biliary tract carcinoma. Bcl-2/Bax may be involved, at least in part, in the apoptotic activity in extrahepatic biliary carcinoma. PMID:14606101

2017-03-01

A 67-year-old man was admitted to our hospital after episodes of syncope preceded by malaise and diffuse neck and chest discomfort. No family history of cardiac disease was reported. Laboratory workup was within normal limits, including D-dimers, serum troponin I and arterial blood gases. The electrocardiogram showed sinus rhythm with T-wave inversion in leads V1 to V3. Computed tomography angiography to investigate pulmonary embolism showed no abnormal findings. Transthoracic echocardiography (TTE) displayed massive enlargement of the right ventricle with intact interatrial septum and no pulmonary hypertension. Cardiac magnetic resonance imaging (MRI) confirmed right ventricular (RV) dilatation and revealed marked hypokinesia/akinesia of the lateral wall. Exercise stress testing was negative for ischemia. According to the 2010 Task Force criteria for arrhythmogenic right ventricular dysplasia (ARVD), this patient presented two major criteria (global or regional dysfunction and structural alterations: by MRI, regional RV akinesia or dyskinesia or dyssynchronous RV contraction and RV ejection fraction ≤40%, and repolarization abnormalities: inverted T waves in right precordial leads [V1, V2, and V3]); and one minor criterion (>500 ventricular extrasystoles per 24 hours by Holter), and so a diagnosis of ARVD was made. After electrophysiologic study (EPS) the patient received an implantable cardioverter-defibrillator (ICD). This late clinical presentation of ARVD highlights the importance of TTE screening, possibly complemented by MRI. The associated risk of sudden death was assessed by EPS leading to the implantation of an ICD. Genetic association studies should be offered to the offspring of all ARVD patients.

Background: Punctate or stippled cartilaginous calcifications are associated with many conditions, including chromosomal, infectious, endocrine, and teratogenic etiologies. Some of these conditions are clinically mild, while others are lethal. Accurate diagnosis can prove instrumental in clinical management and in genetic counseling. Objective: To describe the diagnostic radiographic features seen in Pacman dysplasia, a distinct autosomal recessive, lethal skeletal dysplasia. Materials and methods: We present the fourth reported case of Pacman dysplasia and compare the findings seen in our patient with the three previously described patients. Results: Invariable and variable radiographic findings were seen in all four cases of histologically proven Pacman dysplasia. Conclusion: Pacman dysplasia presents both constant and variable diagnostic radiographic features. (orig.)

Inflammatory myofibroblastic tumor appendix with concomitant mucosal dysplasia, simulating pseudomyxoma on preoperative aspiration cytology

2012-01-01

Full Text Available Inflammatory myofibroblastic tumor (IMT has been described as a pseudosarcomatous proliferation of spindled myofibroblasts admixed with lymphoplasmacytic cells. The various terminologies like inflammatory pseudotumor, plasma cell granuloma, and inflammatory myofibrohistiocytic proliferation, used to describe this entity, highlight the controversial etiopathogenesis of this relatively indolent neoplasm. IMT has now been described in different anatomic locations. However, cases occurring in the gastrointestinal tract are rare with very few cases described in the appendix. We present a case of inflammatory myofibroblastic tumor appendix with mucosal dysplasia in a 41-year-old male, presenting with abdominal pain and lump in the right iliac fossa. Aspiration cytology yielded few atypical epithelial cells and spindle cells in a mucinous background, suggesting the possibility of pseudomyxoma peritonei. Awareness of IMT appendix with rare presence of mucosal dysplasia may help in preventing overzealous resection, especially in situations that on preoperative evaluation may suggest malignancy.

The aim of this study was to assess the prevalence and risk factors predictive of dysplasia among women seen in a gynecologic oncology service with the cytologic diagnosis of atypical squamous cells of undetermined significance (ASCUS) on Papanicolaou smears obtained by the ThinPrep method. Patients with ASCUS ThinPrep Papanicolaou smears seen at the Division of Gynecologic Oncology, University of Vermont, between 1997 and 1999 were identified. The cytologic smears were reviewed and subtyped into reactive or suggestive of squamous intraepithelial lesion (SIL). The charts of these patients were reviewed and the following information was abstracted: age, gravidity, parity, menopausal status, use of hormonal replacement therapy, smoking, history of pelvic cancer, history of radiation therapy, history of abnormal Papanicolaou smear and its treatment, history of human papillomavirus (HPV) infection, and follow-up information including results of repeat Papanicolaou smears, colposcopy, and biopsies. The prevalence of dysplasia was calculated. The demographic features of women with ASCUS, reactive, were compared with those with ASCUS, SIL, using a two-sample t test, chi(2), and Fisher's exact test. Risk factors predictive of dysplasia were calculated using the odds ratio and the 95% confidence interval. P ASCUS on ThinPrep Papanicolaou smear were identified; 63 patients had ASCUS, reactive, and 63 patients had ASCUS, SIL. The demographic features of both groups were similar. The overall prevalence of dysplasia was 15.9% and was significantly higher among women with ASCUS, SIL, than among women with ASCUS, reactive (25.4% versus 6.4%, P = 0.003). The type of ASCUS cytology (reactive versus SIL), smoking, and history of HPV were significant risk factors for dysplasia (P = 0.003, 0.037, and 0. 042, respectively). The prevalence of dysplasia among women seen in a gynecologic oncology service with ASCUS cytology on ThinPrep Papanicolaou smears is 15.9%. Women with ASCUS favor

Asphyxiating Thoracic Dysplasia is the most frequent form of Small Thorax - Short Rib Syndromes. Asphyxiating Thoracic Dysplasia in two patients with different clinical course is reported. Radiographic examination is the only method to diagnose Asphyxiating Thoracic Dysplasia with certainty. The correct diagnosis is important for prognostication and genetic counseling. It also excludes the necessity of further, often expensive investigations. (author)

The Greig cephalopolysyndactyly syndrome

Directory of Open Access Journals (Sweden)

Biesecker Leslie G

2008-04-01

Full Text Available Abstract The Greig cephalopolysyndactyly syndrome (GCPS is a pleiotropic, multiple congenital anomaly syndrome. It is rare, but precise estimates of incidence are difficult to determine, as ascertainment is erratic (estimated range 1–9/1,000,000. The primary findings include hypertelorism, macrocephaly with frontal bossing, and polysyndactyly. The polydactyly is most commonly preaxial of the feet and postaxial in the hands, with variable cutaneous syndactyly, but the limb findings vary significantly. Other low frequency findings include central nervous system (CNS anomalies, hernias, and cognitive impairment. GCPS is caused by loss of function mutations in the GLI3 transcription factor gene and is inherited in an autosomal dominant pattern. The disorder is allelic to the Pallister-Hall syndrome and one form of the acrocallosal syndrome. Clinical diagnosis is challenging because the findings of GCPS are relatively non-specific, and no specific and sensitive clinical have been delineated. For this reason, we have proposed a combined clinical-molecular definition for the syndrome. A presumptive diagnosis of GCPS can be made if the patient has the classic triad of preaxial polydactyly with cutaneous syndactyly of at least one limb, hypertelorism, and macrocephaly. Patients with a phenotype consistent with GCPS (but which may not manifest all three attributes listed above and a GLI3 mutation may be diagnosed definitively with GCPS. In addition, persons with a GCPS-consistent phenotype who are related to a definitively diagnosed family member in a pattern consistent with autosomal dominant inheritance may be diagnosed definitively as well. Antenatal molecular diagnosis is technically straightforward to perform. Differential diagnoses include preaxial polydactyly type 4, the GCPS contiguous gene syndrome, acrocallosal syndrome, Gorlin syndrome, Carpenter syndrome, and Teebi syndrome. Treatment of the disorder is symptomatic, with plastic or

Bone dysplasias comprise of a condition where the normal bone is replaced with fibrous tissue. Periapical Cemento-Osseous Dysplasia (PCOD) is a benign fibro-osseous condition where bone tissue is supplanted with fibrous tissue and cementum-like material. This condition affects mostly mandibular anterior region and rarely occurs in the maxilla. PCOD is seen above 30 years of age and has slight female predilection. Generally the teeth related to such lesions appear to be vital and are usually asymptomatic. These lesions are mostly seen during routine radiographic examination whose presentation may vary from complete radiolucency to dense radiopacity. The advent of Cone Beam Computed Tomography (CBCT) has brought a massive change in the field of dentistry which has become an important tool for diagnosis. Hence we hereby present an unusual case of cemento-osseous dysplasia in an unfamiliar location with an atypical presentation. The shape of the pathology was completely idiosyncratic and different from an orthodox lesion of COD, as the lesion was observed to grow out of the palatal surface with a prominent palatal expansion. This case highlights the importance of CBCT in radiographic diagnosis and in evaluating the characteristics of such lesion, which present with high diagnostic dilemma.

Spondyloepiphyseal dysplasia congenita is a form of primarily short trunk dwarfism, that is manifest at birth but generally has not been regarded as a cause of lethal neonatal dwarfism. Seven neonates with severe dwarfism are presented. The first survived the newborn period, but the other six were early neonatal deaths. All displayed the clinical and radiologic features of spondyloepiphyseal dysplasia congenita. The striking similarities between spondyloepiphyseal dysplasia congenita and achondrogenesis type 2 are discussed. (orig.) [de

Full Text Available Skeletal dysplasias are challenging for diagnostics and treatment. We present a series of fifteen patients with different forms of skeletal dysplasias with age ranged from 6 to 17 years with variable clinical presentations managed as a part of the project of scientific cooperation between Turner Paediatric Orthopaedic Institute and Orthopaedic Hospital Vienna-Speising. The spectrum of diagnoses included multiple epiphyseal dysplasia, spondyloepiphyseal dysplasia congenita, diastrophic dysplasia, metaphyseal dysplasia, spondylometaphyseal dysplasia, Stickler syndrome, Kniest dysplasia, and anauxetic dysplasia. Complex treatment, which included axial correction and juxta-articular realignment, was performed as a single-stage, or consecutive surgery. Surgical techniques included corrective osteotomies with internal fixation, guided growth technique and external fixation devices. Best results (full axial correction, normal alignment of the joint were achieved in 8 patients, including 2 patients with metaphyseal dysplasia, 2 patients with multiple epyphyseal dysplasia, 2 patients with spondyloepyphyseal dysplasia, patient with Stickler syndrome and patient with spondylometaphyseal dysplasia. Good results (partial correction at the present time were seen in 4 patients (2 patients with Kniest dysplasia, 1 - with multiple epyphyseal dysplasia and 1 - with anauxetic dysplasia. Satisfactory results (non-progressive condition in previous progression were obtained in 2 patients with diastrophic dysplasia, and poor results (progression of the deformity - in 1 patient with diastrophic dysplasia. Positive results in most of the cases of our series make promising future for usage of complex approach for orthopedic management of children with skeletal dysplasias; advanced international cooperation is productive and helpful for diagnostics and management of rare diseases.

The Bone Dysplasia Ontology: integrating genotype and phenotype information in the skeletal dysplasia domain

Directory of Open Access Journals (Sweden)

Groza Tudor

2012-03-01

Full Text Available Abstract Background Skeletal dysplasias are a rare and heterogeneous group of genetic disorders affecting skeletal development. Patients with skeletal dysplasias suffer from many complex medical issues including degenerative joint disease and neurological complications. Because the data and expertise associated with this field is both sparse and disparate, significant benefits will potentially accrue from the availability of an ontology that provides a shared conceptualisation of the domain knowledge and enables data integration, cross-referencing and advanced reasoning across the relevant but distributed data sources. Results We introduce the design considerations and implementation details of the Bone Dysplasia Ontology. We also describe the different components of the ontology, including a comprehensive and formal representation of the skeletal dysplasia domain as well as the related genotypes and phenotypes. We then briefly describe SKELETOME, a community-driven knowledge curation platform that is underpinned by the Bone Dysplasia Ontology. SKELETOME enables domain experts to use, refine and extend and apply the ontology without any prior ontology engineering experience--to advance the body of knowledge in the skeletal dysplasia field. Conclusions The Bone Dysplasia Ontology represents the most comprehensive structured knowledge source for the skeletal dysplasias domain. It provides the means for integrating and annotating clinical and research data, not only at the generic domain knowledge level, but also at the level of individual patient case studies. It enables links between individual cases and publicly available genotype and phenotype resources based on a community-driven curation process that ensures a shared conceptualisation of the domain knowledge and its continuous incremental evolution.

TRPV4 related skeletal dysplasias: a phenotypic spectrum highlighted byclinical, radiographic, and molecular studies in 21 new families

Directory of Open Access Journals (Sweden)

Sillence David

2011-06-01

Full Text Available Abstract Background The TRPV4 gene encodes a calcium-permeable ion-channel that is widely expressed, responds to many different stimuli and participates in an extraordinarily wide range of physiologic processes. Autosomal dominant brachyolmia, spondylometaphyseal dysplasia Kozlowski type (SMDK and metatropic dysplasia (MD are currently considered three distinct skeletal dysplasias with some shared clinical features, including short stature, platyspondyly, and progressive scoliosis. Recently, TRPV4 mutations have been found in patients diagnosed with these skeletal phenotypes. Methods and Results We critically analysed the clinical and radiographic data on 26 subjects from 21 families, all of whom had a clinical diagnosis of one of the conditions described above: 15 with MD; 9 with SMDK; and 2 with brachyolmia. We sequenced TRPV4 and identified 9 different mutations in 22 patients, 4 previously described, and 5 novel. There were 4 mutation-negative cases: one with MD and one with SMDK, both displaying atypical clinical and radiographic features for these diagnoses; and two with brachyolmia, who had isolated spine changes and no metaphyseal involvement. Conclusions Our data suggest the TRPV4 skeletal dysplasias represent a continuum of severity with areas of phenotypic overlap, even within the same family. We propose that AD brachyolmia lies at the mildest end of this spectrum and, since all cases described with this diagnosis and TRPV4 mutations display metaphyseal changes, we suggest that it is not a distinct entity but represents the mildest phenotypic expression of SMDK.

The purpose of this study is to analyze the demographic, clinical, and radiographic presentations of osseous dysplasia of the jaws in western Pennsylvania patients and its associated complications. The clinical records and radiographs of patients diagnosed with osseous (cement-osseous) dysplasia were retrieved from the electronic health record of the University of Pittsburgh, School of Dental Medicine from 2007 to 2012. All cases were reviewed; the WHO criteria and classification for osseous dysplasia was used. Clinical and demographic data, radiographic findings, and final diagnoses were collected and analyzed. 35 cases of osseous dysplasia were retrieved over the six-year period.The majority (33) were females [94.3%], with ages ranging from 26 to 89 years, with a mean age of 53.9 years +/- standard deviation of 15.6 years, 32 [91.4%] were African Americans and 3 [8.6%] were Caucasians. 17 [48.6%] were florid osseous dysplasia, 13 [37.1%] periapical osseous dysplasia and 5 [14.3%] focal osseous dysplasia. Of the 35 patients only 8 [22.9%] patients were symptomatic. All florid osseous dysplasia patients were African American females, with 7 of the patients being symptomatic and the commonest symptom being pain. Also, all periapical osseous dysplasia patients were African Americans (12 females and 1 male), with 1 of the patients presenting with widening of the diastema. Of the focal osseous dysplasia patients, 3 were Caucasians and 2 African American (4 females and 1 male). The cases occurred mostly in African American females with a peak incidence in the fifth and sixth decades of life; most cases occurred in the mandible. The commonest form of osseous dysplasias was the florid osseous dysplasia which is most likely to present with symptoms.

To explore differences in blood cytokine profiles among distinct bronchopulmonary dysplasia (BPD) patterns. We evaluated blood spots collected from 943 infants born at ≤1000 g and surviving to 28 days on postnatal days 1, 3, 7, 14, and 21 for 25 cytokines. Infants were assigned to the following lung disease patterns: (1) no lung disease (NLD); (2) respiratory distress syndrome without BPD; (3) classic BPD (persistent exposure to supplemental oxygen until 28 days of age); or (4) atypical BPD (period without supplemental oxygen before 28 days). Median cytokine levels for infants with BPD were compared with the IQR of results among infants with NLD. The distribution of enrolled infants by group was as follows: 69 (NLD), 73 (respiratory distress syndrome), 381 (classic BPD), and 160 (atypical BPD). The remaining 260 infants could not be classified because of missing data (104) or not fitting a predefined pattern (156). Median levels of 3 cytokines (elevated interleukin [IL]-8, matrix metalloproteinase-9; decreased granulocyte macrophage colony-stimulating factor) fell outside the IQR for at least 2 time points in both infants with atypical and classic BPD. Profiles of 7 cytokines (IL-6, IL-10, IL-18, macrophage inflammatory protein-1α, C-reactive protein, brain-derived neurotrophic factor, regulated on activation, normal T cell expressed and secreted) differed between infants with classic and atypical BPD. Blood cytokine profiles may differ between infants developing classic and atypical BPD. These dissimilarities suggest the possibility that differing mechanisms could explain the varied patterns of pathophysiology of lung disease in extremely premature infants.

Focal cortical dysplasia is a malformation of cortical development, which is the most common cause of medically refractory epilepsy in the pediatric population and the second/third most common etiology of medically intractable seizures in adults. Both genetic and acquired factors are involved in the pathogenesis of cortical dysplasia. Numerous classifications of the complex structural abnormalities of focal cortical dysplasia have been proposed – from Taylor et al. in 1971 to the last modification of Palmini classification made by Blumcke in 2011. In general, three types of cortical dysplasia are recognized. Type I focal cortical dysplasia with mild symptomatic expression and late onset, is more often seen in adults, with changes present in the temporal lobe. Clinical symptoms are more severe in type II of cortical dysplasia usually seen in children. In this type, more extensive changes occur outside the temporal lobe with predilection for the frontal lobes. New type III is one of the above dysplasias with associated another principal lesion as hippocampal sclerosis, tumor, vascular malformation or acquired pathology during early life. Brain MRI imaging shows abnormalities in the majority of type II dysplasias and in only some of type I cortical dysplasias. The most common findings on MRI imaging include: focal cortical thickening or thinning, areas of focal brain atrophy, blurring of the gray-white junction, increased signal on T2- and FLAIR-weighted images in the gray and subcortical white matter often tapering toward the ventricle. On the basis of the MRI findings, it is possible to differentiate between type I and type II cortical dysplasia. A complete resection of the epileptogenic zone is required for seizure-free life. MRI imaging is very helpful to identify those patients who are likely to benefit from surgical treatment in a group of patients with drug-resistant epilepsy. However, in type I cortical dysplasia, MR imaging is often normal, and also in both

Full Text Available Ectodermal dysplasias are a large hereditary group of disorders which are usually manifested as X-linked recessive disorders and have a full expression in males, whereas females show little to no signs of the disorder. The two most common types of ectodermal dysplasias are hypohidrotic ectodermal dysplasia (Christ-Siemens-Touraine syndrome and hidrotic ectodermal dysplasia (Clouston syndrome. Hypohidrotic ectodermal dysplasia is characterized by hypodontia, hypotrichosis, and hypohidrosis. Here, we present two female sibling cases of hypohidrotic ectodermal dysplasia.

At a workshop coordinated by the WHO Collaborating Centre for Oral Cancer and Precancer in the United Kingdom issues related to potentially malignant disorders of the oral cavity were discussed by an expert group. The consensus views of the Working Group are presented in a series of papers....... In this report, we review the oral epithelial dysplasia classification systems. The three classification schemes [oral epithelial dysplasia scoring system, squamous intraepithelial neoplasia and Ljubljana classification] were presented and the Working Group recommended epithelial dysplasia grading for routine...... use. Although most oral pathologists possibly recognize and accept the criteria for grading epithelial dysplasia, firstly based on architectural features and then of cytology, there is great variability in their interpretation of the presence, degree and significance of the individual criteria...

Bone scintigraphy in polyostotic fibrous dysplasia

Fibrous dysplasia is a benign skeletal disorder of unknown aetiology. Fibrous dysplasia characteristically involves the fibrous replacement of portions of the medullary cavities of a single bone (monostotic) or multiple bones (polyostotic). Bones typically involved include the femurs, tibiae, ribs and maxillae. The polyostotic form may be accompanied by skin pigmentation and endocrine abnormalities (McCune Allbright Syndrome). Radiological findings in fibrous dysplasia are variable, ranging from completely radiolucent to radio-opaque lesions, depending on the amount of fibrous or osseous tissue deposited in the medulla. The most common radiographic finding is that of a ground glass-like semi-opaque lesion. Case reports on scintigraphic manifestation of fibrous dysplasia are scanty. We present radiological and scintigraphic findings of polyostotic fibrous dysplasia in a young male. (authors). 3 refs., 1 fig.

Jansen type of spondylometaphyseal dysplasia

International Nuclear Information System (INIS)

Campbell, J.B.; Kozlowski, K.; Lejman, T.; Sulko, J.

2000-01-01

Metaphyseal dysplasia, type Jansen (JMD), is a rare skeletal dysplasia with characteristic radiographic abnormalities. Of the various types of metaphyseal dysplasia, JMD shows the most severe alteration in metaphyseal architecture. All of the long tubular bones, including those of the hands and feet, show metaphyseal irregularity with a fragmented appearance and slight widening. The adjacent physes are abnormally widened, while the epiphyses tend to be slightly enlarged, rounded but otherwise normal. The spine in infancy and childhood usually appears normal. This report describes a young girl with metaphyseal changes typical of JMD except for the hands and feet, which appeared normal. She also showed very unusual abnormalities of the spine. This appears, therefore, to represent a unique osteochondrodysplasia for which we propose the term spondylometaphyseal dysplasia, type Jansen. (orig.)

Gracile bone dysplasias constitute a group of disorders characterised by extremely slender bones with or without fractures. We report four newborns, two of whom showed multiple fractures. Two babies had osteocraniostenosis and one had features of oligohydramnios sequence. The diagnosis in the fourth newborn, which showed thin long bones and clavicles and extremely thin, poorly ossified ribs, is uncertain. Exact diagnosis of a gracile bone dysplasia is important for genetic counselling and medico-legal reasons. (orig.)

Patients with extensive ulcerative colitis (UC) of longer than 8 years duration are at high risk for the development of colorectal cancer. The cancers in these patients appear to develop in a stepwise manner with progressive histological changes from negative for dysplasia → indefinite for dysplasia → dysplasia → cancer. The aim of this study was to determine the timing and extent of genomic instability in the progression of UC dysplasia and cancer. Using two polymerase chain reaction (PCR)-based DNA fingerprinting methods, arbitrarily primed PCR and intersimple sequence repeat PCR, we assessed DNA sequence variation in biopsies across the spectrum of cancerous, dysplastic, and nondysplastic mucosa. UC patients with dysplasia/cancer had substantial genomic instability in both their dysplastic and nondysplastic colonic mucosa, whereas instability was not present in the majority of UC patients without dysplasia/cancer. The degree of instability in nondysplastic tissue was similar to that of dysplastic/cancerous mucosa from the same patient, suggesting that this instability was widespread and reached the maximum level early in neoplastic progression. These results suggest that UC patients who develop dysplasia or cancer have an underlying process of genomic instability in their colonic mucosa whereas UC patients who are dysplasia-free do not.

In contrast to longitudinal deficiencies, phocomelia is considered a transverse, intercalated segmental dysplasia. Most patients demonstrate severe, but not otherwise classifiable, upper-extremity deformities, which usually cannot be placed into one of three previously described phocomelia groups. Additionally, these phocomelic extremities do not demonstrate true segmental deficits; the limb is also abnormal proximal and distal to the segmental defect. The purpose of this investigation was to present evidence that upper-extremity abnormalities in patients previously diagnosed as having phocomelia in fact represent a proximal continuum of radial or ulnar longitudinal dysplasia. The charts and radiographs of forty-one patients (sixty extremities) diagnosed as having upper-extremity phocomelia were reviewed retrospectively. On the basis of the findings on the radiographs, the disorders were categorized into three groups: (1) proximal radial longitudinal dysplasia, which was characterized by an absent proximal part of the humerus, a nearly normal distal part of the humerus, a completely absent radius, and a radial-sided hand dysplasia; (2) proximal ulnar longitudinal dysplasia, characterized by a short one-bone upper extremity that bifurcated distally and by severe hand abnormalities compatible with ulnar dysplasia; and (3) severe combined dysplasia, with type A characterized by an absence of the forearm segment (i.e., the radius and ulna) and type B characterized by absence of the arm and forearm (i.e., the hand attached to the thorax). Twenty-nine limbs in sixteen patients could be classified as having proximal radial longitudinal dysplasia. Systemic medical conditions such as thrombocytopenia-absent radius syndrome were common in those patients, but additional musculoskeletal conditions were rare. Twenty limbs in seventeen patients could be classified as having proximal ulnar longitudinal dysplasia. Associated musculoskeletal abnormalities, such as proximal femoral

To present a case of expansive focal cemento-osseous dysplasia and emphasize the importance of differential diagnosis. Cemento-osseous dysplasia is categorized into three subtypes on the basis of the clinical and radiographic features: Periapical, focal and florid. The focal type exhibits a single site of involvement in any tooth-bearing or edentulous area of the jaws. These lesions are usually asymptomatic; therefore, they are frequently diagnosed incidentally during routine radiographic examinations. Lesions are usually benign, show limited growth, and do not require further surgical intervention, but periodic follow-up is recommended because occasionally, this type of dysplasia progresses into florid osseous dysplasia and simple bone cysts are formed. A 24-year-old female patient was referred to our clinic for swelling in the left edentulous mandibular premolarmolar region and felt discomfort when she wore her prosthetics. She had no pain, tenderness or paresthesia. Clinical examination showed that the swelling in the posterior mandible that was firm, nonfluctuant and covered by normal mucosa. On panoramic radiography and computed tomography, a well defined lesion of approximately 1.5 cm in diameter of mixed density was observed. The swelling increased slightly in size over 2 years making it difficult to use prosthetics and, therefore, the lesion was totally excised under local anesthesia, and surgical specimens were submitted for histopathological examination. The histopathological diagnosis was focal cemento-osseous dysplasia. In the present case, because of the increasing size of the swelling making it difficult to use prosthetics, young age of the patient and localization of the lesion, in the initial examination, cemento-ossifying fibroma was suspected, and the lesion was excised surgically; the histopathological diagnosis confirmed it as focal cemento-osseous dysplasia. We present a case of expansive focal cemento-osseous dysplasia. Differential diagnosis

Full Text Available Hereditary hypohidrotic ectodermal dysplasia, also called the Christ-Siemens-Touraine Syndrome is characterized by congenital dysplasia of one or more ectodermal structures and is manifested by hypohidrosis, hypotrichosis and hypodontia. It is usually an X-linked recessive mendelian character which is rarely seen in males. It results from abnormal morphogenesis of cutaneous and oral embryonic ectoderm. Patients with this disorder exhibit smooth , thin and dry skin, fine and blond scanty hair. Intra-orally anodontia or hypodontia, with impaired development of alveolar process is seen. A case report of a rare case of this disorder in a female patient aged 18 years is hereby presented.

Full Text Available In this thesis, our purpose is to show that using physiotherapy on patients with hip dysplasia from the very beginning, in the first months of life, helps treating them faster. Common literature proposes to use physiotherapy on patients with hip dysplasia either after their recovery or in the terminal phase of recovery, claiming that any earlier intervention will prolong the hip recovery. The effects of hip dysplasia reflect over the whole musculoskeletal system, while it hinders the knees (genu valgum, the ankles (ankle valgus, calcaneal valgus and the spine (scoliosis especially at the lumbar level. The most spectacular are at the hip level, that is why we made an analytical evaluation only for this joint. To show the importance of physiotherapy for children with hip dysplasia we started from the hypothesis: untimely treatment for children with hip dysplasia has improved results in functional recovery and in obtaining a better stability, without the necessity of orthopedics or surgical interventions. The research methods used in this study are: the observation method, the bibliographic study method, the experimental method, the graphics method and the statistical mathematical method to process the data and to represent the results graphically. In the end, the results obtained are significantly different from the initial evaluations and we came to the conclusion that starting an untimely analytical kinetic treatment and globally personalizing it to every patient improves stability and biomechanical parameters for the hip.

Ectodermal dysplasia: a genetic review.

Ectodermal dysplasia is a rare hereditary disorder with a characteristic physiognomy. It is a genetic disorder affecting the development or function of the teeth, hair, nails and sweat glands. Depending on the particular syndrome ectodermal dysplasia can also affect the skin, the lens or retina of the eye, parts of the inner ear, the development of fingers and toes, the nerves and other parts of the body. Each syndrome usually involves a different combination of symptoms, which can range from mild to severe. The history and lessons learned from hypohidrotic ectodermal dysplasia (HED) may serve as an example for unraveling of the cause and pathogenesis of other ectodermal dysplasia syndromes by demonstrating that phenotypically identical syndromes can be caused by mutations in different genes (EDA, EDAR, EDARADD), that mutations in the same gene can lead to different phenotypes and that mutations in the genes further downstream in the same signaling pathway (NEMO) may modify the phenotype quite profoundly. The aim of this paper is to describe and discuss the etiology, genetic review, clinical manifestations and treatment options of this hereditary disorder.

Full Text Available The bony pelvis is constituted by the ilium, ischium, pubis, and sacrum. The pelvic radiograph is an important component of the skeletal survey performed in suspected skeletal dysplasia. Most of the common skeletal dysplasias have either minor or major radiological abnormalities; hence, knowledge of the normal radiological appearance of bony pelvis is vital for recognizing the early signs of various skeletal dysplasias. This article discusses many common and some uncommon radiological findings on pelvic radiographs along with the specific dysplasia in which they are seen; common differential diagnostic considerations are also discussed.

In a longitudinal case-control study, we followed 81 subjects with dysplasia of the hip and 136 control subjects without dysplasia for ten years assessing radiological evidence of degeneration of the hip at admission and follow-up. There were no cases of subluxation in the group with dysplasia....... Neither subjects with dysplasia nor controls had radiological signs of ongoing degenerative disease at admission. The primary radiological discriminator of degeneration of the hip was a change in the minimum joint space width over time. There were no significant differences between these with dysplasia...... and controls in regard to age, body mass index or occupational exposure to daily repeated lifting at admission.We found no significant differences in the reduction of the joint space width at follow-up between subjects with dysplasia and the control subjects nor in self-reported pain in the hip...

Since January 1984 all newborns and infants with skeletal dysplasias and chromosomal aberrations were investigated by hip US, in addition to plain x-ray surveys. The authors observed one chondroectodermal dysplasia, one congenital spondyloepiphysial dysplasia, one cleidocranial dysplasia, one fibrochondrogenesis, two diastrophic dysplasias, and eight trisomies. The abnormalities of the hip joints could be demonstrated, and were compared with the findings on plain films. Especially skeletal dysplasias with abundant presence of cartilage were well visible. The newborn with trisomies showed normal hip joints. In the authors' opinion, all newborns with skeletal dysplasias should be investigated by hip sonography, in addition to skeletal radiography

Congenital dysplasia of the humerus is very rare. It is characteristically seen in omodysplasia and has also been reported as one of the associated features of Larsen's syndrome. We report a 4-year-old girl with bilateral humero-ulnar dysplasia, with dislocation of the elbows, facial dysmorphism, ball-and-socket ankles and foot deformities. Although the elbow dysplasia is similar to that seen in Larsen's syndrome, other pathognomic features of Larsen's syndrome were absent. The changes seen in the elbows in this patient are also different from those encountered in omodysplasia. We believe that this condition may be a distinct form of skeletal dysplasia hitherto undescribed. (orig.)

The aim of this retrospective hospital-based study was to elucidate the dentomaxillofacial characteristics of ectodermal dysplasia. Six Japanese individuals (one male and five female; age range, 12.7-27.2 years) underwent comprehensive examinations, including history recording, cephalometric analysis, panoramic radiography, and analysis of dental models. All the subjects had two or more major manifestations for clinical diagnosis of ectodermal dysplasia (e.g., defects of hair, teeth, nails, and sweat glands). They presented hypodontia (mean number of missing teeth, 9.5; range, 5-14), especially in the premolar region, and enamel dysplasia. Five subjects had bilateral molar occlusion, whereas one subject had unilateral molar occlusion. The common skeletal features were small facial height, maxillary hypoplasia, counterclockwise rotation of the mandible, and mandibular protrusion. Interestingly, the maxillary first molars were located in higher positions and the upper anterior facial height was smaller than the Japanese norm. The results suggest that vertical and anteroposterior maxillary growth retardation, rather than lack of occlusal support due to hypodontia, leads to reduced anterior facial height in individuals with ectodermal dysplasia. © 2014 Japanese Teratology Society.

Chondroectodermal dysplasia: a rare syndrome.

Dana Tahririan

2014-06-01

Full Text Available Chondroectodermal dysplasia (Ellis-Van Creveld syndrome is a rare autosomal recessive congenital abnormality. This syndrome is characterized by a spectrum of clinical findings, among which chondrodystrophy, polydactyly, ectodermal dysplasia, and congenital cardiac anomalies are the most common. It is imperative to not overlook the cardiac complications in patients with this syndrome during dental procedures. The case presented here, although quite rare, was detected under normal conditions and can be alarming for dental care providers. Clinical reports outline the classical and unusual oral and dental manifestations, which help health care providers diagnose chondroectodermal dysplasia, and refer patients with this syndrome to appropriate health care professionals to receive treatment to prevent further cardiac complications and bone deformities.

2015-01-01

Full Text Available Fibrous dysplasia is a benign fibroosseous bone dysplasia that can involve single (monostotic or multiple (polyostotic bones. Monostotic form is more frequent in the jaws. It is termed as craniofacial fibrous dysplasia, when it involves, though rarely, adjacent craniofacial bones. A 16-year-old girl consulted for a painless swelling in the right posterior mandible for two years. Panoramic radiography revealed ground-glass ill-defined lesions in the three different regions of the maxilla and mandible. Axial CT scan (bone window showed multiple lesions involving skull base and facial bones. Despite lesions in the skull base, the patient had no abnormal neurological findings. The lesion was diagnosed as fibrous dysplasia based on radiological and histopathological examination. In this paper, CT findings and differential diagnosis of CFD are discussed. CT is a useful imaging technique for CFD cases.

The aim of this prospective study was to improve the quality of life of and reduce morbidity for patients with ectodermal dysplasia by assessing their actual and potential ENT pathologies, and offering methods of prevention and treatment. The study was conducted between 2006 and 2008 and included 23 patients diagnosed with ectodermal dysplasia. The major symptoms of ectodermal dysplasia were evaluated. Patient histories were obtained in all cases, and a complete head and neck examination was carried out. Of the 23 patients (11 males and 12 females, aged 5 to 45 years) diagnosed with ectodermal dysplasia, 22 had hypohidrotic ectodermal dysplasia and 1 had ectrodactyly-ectodermal dysplasia-clefting syndrome. In all patients diagnosed with hypohidrotic ectodermal dysplasia, the salivary glands were examined by ultrasonography and, when necessary, by scintigraphy. Hearing defects in patients with otologic problems were determined by audiometric examination: 39.1% of the patients had hearing loss, 43.5% had otitis media, and 39.1% had impacted cerumen. The most common rhinologic findings were saddle nose deformity in 56.5%, nasal obstruction and nasal dryness (52.2% each), and chronic rhinitis/rhinosinusitis (34.8%). The most common oral and oropharyngeal findings were difficulty chewing in 82.6% and dry mouth in 78.3%. All 23 patients had required dental work. Because this disorder affects several aspects of the body, its treatment requires a multidisciplinary approach, with the otolaryngologist being a vital part of the management team.

Ectodermal dysplasia (ED) syndrome comprises a large, heterogeneous group of inherited disorders that are defined by primary defects in the development of 2 or more tissues derived from the embryonic ectoderm. The tissues primarily involved are the skin and its appendages (including hair follicles, eccrine glands, sebaceous glands, nails) and teeth. The clinical features include sparse hair, abnormal or missing teeth, and an inability to sweat due to lack of sweat glands. One such case report of ectodermal dysplasia is presented here.

A five-and-a-half-year-old girl started experiencing progressive left hemiparesis at age two and a half years. At age five years and four months she started presenting clusters of asymmetric periodic epileptic spasms with no hypsarrhythmia. The ictal EEG showed periodic, constant and stereotyped complexes. Serial brain imaging revealed progressive atrophy of the right hemisphere with increased T2 signal on MRI. She underwent a right hemispherotomy, and histological examination showed signs of inflammation and features of focal cortical dysplasia (FCD). She has been seizure-free for 16 months. This case is unique in the following aspects: the presence of typical Rasmussen encephalitis features of progressive unilateral brain involvement without seizures, a delay of almost three years prior to seizure onset; an atypical seizure type presentation with periodic epileptic spasms and the presence of FCD associated with inflammatory changes.

2006-01-01

Flattening of the epiphyses of long bones is seen in several skeletal dysplasias and standardized measurements on a radiograph of the knee to detect skeletal dysplasias using this feature have been described. Since then only two other studies in which this method was used have been published, and both included only a small number of children and neither had a control group. In addition, the Dutch National Working Group on Skeletal Dysplasias began to have doubts about the reliability of the method. We therefore decided to re-evaluate its accuracy in a population of children with and without a skeletal dysplasia. To determine the diagnostic value of standardized measurements on conventional AP radiographs of the knee in children with a skeletal dysplasia. Subjects and methods: We measured the distal femoral metaphysis and epiphysis according to the published method on conventional AP radiographs of the knee in 45 healthy children and 52 children with a skeletal dysplasia. We compared graphically the height of the distal femoral epiphysis with its width and with the width of the femoral metaphysis. Receiver operating characteristic (ROC) curves were calculated for each group of children. All graphs showed a considerable overlap between children with a skeletal dysplasia and healthy children. The size of the area under the ROC curves for the different groups was small, varying between 0.567 and 0.653. This method does not discriminate between children with a skeletal dysplasia and healthy children. We therefore consider it to be of little diagnostic value. (orig.)

An Uncommon Reason of Osteoporosis: Spondyloepiphyseal Dysplasia Congenita

Directory of Open Access Journals (Sweden)

2017-12-01

Full Text Available Skeletal dysplasia is a complex and rare disease group that presents with clinical and radiological findings that differ from classical metabolic bone diseases in which bone and cartilage tissue are affected together. Spondyloepiphyseal dysplasia conjenita with involvement of the spine and long bone epiphyses is seen with short stature and short body from birth. Although bone deformities such as shortness of neck and vertebrae, kyphosis, scoliosis, pectus carinatum, genu varum or valgum are frequent, association with osteopenia/osteoporosis has been rarely reported. Although spondyloepiphyseal dysplasia tarda and osteopenia are coexisting in the literature, there is no evidence of the association of spondyloepiphyseal dysplasia tarda and conjunctiva with osteoporosis. In our case report, we presented a patient who was applied to our center with short stature, diagnosed with osteoporosis and spondyloepiphyseal dysplasia congenita by detecting femur head aplasia in radiological imaging.

McCune-Albright syndrome (MAS) is an uncommon polyostotic manifestation of fibrous dysplasia in association with at least one endocrinopathy that is mostly associated with precocious puberty and hyperpigmented skin macules named café-au-lait spots. We present an atypical manifestation of McCune-Albright syndrome in a 19-year-old man with the uncommon association of polyostotic fibrous dysplasia and gigantism in the absence of café-au-lait spots and precocious puberty. He presented with a height increase to 202 cm in the previous 3 years, which had become more progressive in the few months prior. Physical examination revealed only a mild facial asymmetry; however, a computed tomography (CT) scan discovered vast areas of voluminous bones with ground-glass density and thickening involving the craniofacial bones and skull base. Magnetic resonance imaging (MRI) found a right stalk shift of the pituitary with a 20 mm pituitary adenoma. We describe the diagnostic and endoscopic endonasal transsphenoidal approach for excision of the tumor. Georg Thieme Verlag KG Stuttgart · New York.

Florid cemento-osseous dysplasia is a benign and rare tumor of the jaws. It is more commonly seen in middle-aged black women. Most cases are asymptomatic and are found during routine radiographic examination. We report two complicated cases of florid cemento-osseous dysplasia, one with facial deformity and the other with chronic osteitis. The diagnosis of florid cemento-osseous dysplasia is based on clinical and radiological features. The lesions are commonly bilateral and symmetrical. Copyright © 2011.

Ectodermal dysplasias are a large group of syndromes characterized by anomalies in the structures of ectodermal origin. There are 2 major types of this disorder, based on clinical findings: hypohidrotic ectodermal dysplasia and hidrotic ectodermal dysplasia. This clinical classification is very important because clinical professionals involved with this disease need first a clear and practical method of diagnosis. The main oral manifestation of ectodermal dysplasia may be expressed as hypodontia. Thus, dental professionals may be the first to diagnose ectodermal dysplasia. The present article reports one case of each of the main types (hypohidrotic and hidrotic) of ectodermal dysplasia and the authors review the literature regarding the pathogenesis, clinical features, and therapeutic management of this condition.

Kaftan, H; Adamaszek, M; Hosemann, W

2006-08-01

Mondini dysplasia is a rare malformation of the inner ear commonly associated with loss of hearing and vestibular function. Children with Mondini dysplasia are predisposed to developing a spontaneous cerebrospinal fluid (CSF) leak and recurrent meningitis. If there is no CSF leak but a unilateral hearing loss, the condition may go undiagnosed for years. We describe a 65-year-old man with unrecognized unilateral Mondini dysplasia who presented with CSF leak and meningoencephalitis after minor head trauma. Two operative interventions were undertaken to close the defect properly. Patients with Mondini dysplasia or their parents should be cautioned about the potential hazards of any head trauma.

2010-10-01

Focal cemento-osseous dysplasia is a benign fibro-osseous condition that can be seen in dentate and edentulous patients. It is an asymptomatic lesion and needs no treatment; however follow-up is essential due to the possibility that focal cemento-osseous dysplasia can progress to a condition called florid osseous dysplasia that involves multiple sites. A case report is presented here, along with a review of the differential diagnoses considered in order to reach a final diagnosis of focal cemento-osseous dysplasia.

Ectodermal dysplasia is a complex group of familial disorders with numerous clinical characteristics, with an incidence of 7 in 10000 born alive children. Ectodermal dysplasia affects structures of ectodermal origin like the skin and its appendages as well as other non-ectodermal structures. The most common sites of involvement are the defects in the skin, hair, teeth, nails and sweat glands,which are of ectodermal origin. Though the dermatologists and paediatricians often manage such cases, we report one case of ectodermal dysplasia presenting with atrophic rhinitis.

PurposeTo describe our experience with a large cohort (411 patients from 288 families) of various forms of skeletal dysplasia who were molecularly characterized.MethodsDetailed phenotyping and next-generation sequencing (panel and exome).ResultsOur analysis revealed 224 pathogenic/likely pathogenic variants (54 (24%) of which are novel) in 123 genes with established or tentative links to skeletal dysplasia. In addition, we propose 5 genes as candidate disease genes with suggestive biological links (WNT3A, SUCO, RIN1, DIP2C, and PAN2). Phenotypically, we note that our cohort spans 36 established phenotypic categories by the International Skeletal Dysplasia Nosology, as well as 18 novel skeletal dysplasia phenotypes that could not be classified under these categories, e.g., the novel C3orf17-related skeletal dysplasia. We also describe novel phenotypic aspects of well-known disease genes, e.g., PGAP3-related Toriello-Carey syndrome-like phenotype. We note a strong founder effect for many genes in our cohort, which allowed us to calculate a minimum disease burden for the autosomal recessive forms of skeletal dysplasia in our population (7.16E-04), which is much higher than the global average.ConclusionBy expanding the phenotypic, allelic, and locus heterogeneity of skeletal dysplasia in humans, we hope our study will improve the diagnostic rate of patients with these conditions.GENETICS in MEDICINE advance online publication, 5 April 2018; doi:10.1038/gim.2018.50.

Congenital pulmonary valve stenosis and patent ductus arteriosus are common congenital heart defects in dogs. However, concurrence of atypical pulmonary valve stenosis and patent ductus arteriosus is uncommon. This report describes the anatomic, histopathologic, and echocardiographic features in a dog with concomitant pulmonary valve stenosis and patent ductus arteriosus with atypical pulmonary valve dysplasia that included a fibrous band of tissue. A 1.5-year-old intact female Chihuahua dog weighing 3.3 kg presented with a continuous grade VI cardiac murmur, poor exercise tolerance, and an intermittent cough. Echocardiography indicated pulmonary valve stenosis, a thickened dysplastic valve without annular hypoplasia, and a type IIA patent ductus arteriosus. The pulmonary valve was thick line-shaped in systole and dome-shaped towards the right ventricular outflow tract in diastole. The dog suffered a fatal cardiac arrest during an attempted balloon pulmonary valvuloplasty. Necropsy revealed pulmonary valve dysplasia, commissural fusion, and incomplete opening and closing of the pulmonary valve because of a fibrous band of tissue causing adhesion between the right ventricular outflow tract and the dysplastic intermediate cusp of the valve. A fibrous band of tissue between the right ventricular outflow track and the pulmonary valve should be considered as a cause of pulmonary valve stenosis. Pulmonary valve stenosis and patent ductus arteriosus can have conflicting effects on diastolic and systolic dysfunction, respectively. Therefore, beta-blockers should always be used carefully, particularly in patients with a heart defect where there is concern about left ventricular systolic function.

Renal dysplasia and MRI: a clinician's perspective

Energy Technology Data Exchange (ETDEWEB)

Greenbaum, Larry A. [Emory University, Division of Pediatric Nephrology, Children' s Healthcare of Atlanta, Atlanta, GA (United States)

2008-01-15

Renal dysplasia is a common abnormality in children. The role of MRI in evaluating children with renal dysplasia is evolving. More information is clearly necessary before MRI replaces conventional imaging modalities. In order to appropriately use MRI, the radiologist must have an understanding of the clinical questions that are important in the management of children with renal dysplasia. This review provides background information on renal dysplasia for the pediatric radiologist. The focus is on unilateral disease, especially multicystic dysplastic kidneys, and bilateral dysplasia, which is the most common cause of kidney failure in children. The emphasis is on the important clinical issues, and the potential of MRI as a methodology for providing clinically useful information not otherwise available from other imaging modalities. (orig.)

The scapula as a window to the diagnosis of skeletal dysplasias

International Nuclear Information System (INIS)

Mortier, G.R.; Rimoin, D.L.; Lachman, R.S.

1997-01-01

Evaluation of the scapula can be useful in the diagnosis of skeletal dysplasias and helpful for the classification and delineation of new entities. A review of 2100 computerized cases of skeletal dysplasias in the International Skeletal Dysplasia Registry was performed. We found that the Luton type of platyspondylic lethal skeletal dysplasia differed radiographically from the San Diego type and Torrance type by the presence of two spikes at the inferior angle of the scapula. Hypoplasia of the body of the scapula, which is characteristic for campomelic dysplasia but not for kyphomelic dysplasia, is also present in Antley-Bixler syndrome. Radiographic and clinical similarities between campomelic dysplasia and Antley-Bixler syndrome suggest that they might be related disorders and that the latter condition should be included in the bent-bone dysplasia group. Similarity between the metaphyseal regions of the scapula and the metaphyses of the long tubular bones in the different types of short-rib polydactyly syndrome illustrates the importance of evaluation of the scapula in this group as well as in other well-defined or unknown osteochondrodysplasias.

2015-01-01

To evaluate the possible relationship between flexible flat foot and developmental hip dysplasia in children between six and 15 years of age. Cross-sectional study including 65 patients that had undergone surgery due to residual hip dysplasia or hip dislocation and compared against 75 healthy patients. Flexible flat foot prevalence was measured in each group, with the results showing that 61% of the group with residual hip dysplasia or hip dislocation had this condition, vs. 12% in the healthy group. The statistical analysis shows that the chances of suffering from flexible flat foot, are five times greater in the hip dysplasia or hip dislocation group, than in the healthy group. There is no evidence in the literature showing a relationship between these two conditions, even though they have a common etiology. This study shows a potential measurable relation between this two conditions. Patients with hip dysplasia or dislocation may have a higher chance of presenting flexible flat foot during late childhood, adolescence and adulthood, a fact that suggests a relationship between these two pathologies. Also, patients who seek assistance for the first time because of a flexible flat foot condition without having been evaluated during the first year of life for hip dysplasia, would be better off if evaluated for residual hip dysplasia.

We sought to determine whether cervical dysplasia in the absence of an excisional procedure is associated with an increased risk of preterm birth (PTB) and whether that risk is independent of the presence of a short cervix. This is a cohort study including women with a singleton pregnancy who underwent routine cervical length assessment between 18-23 6/7 weeks of gestation, stratified by cervical dysplasia (ie, no prior dysplasia, prior dysplasia but no excisional procedure, or prior excisional procedure). The frequency of a short cervix (≤2.5 cm) and PTB were compared between groups and multivariable analyses were performed to identify whether: (1) dysplasia alone or a prior excisional procedure was associated with PTB; and (2) whether these factors remained independently associated with PTB after adjusting for the presence of a short cervix. Of the 18,528 women who met inclusion criteria, 3023 (16.3%) had prior dysplasia alone and 1356 (7.3%) had a prior excisional procedure. The frequency of a short cervix for women without dysplasia, with prior dysplasia alone, or with a prior excisional procedure was 0.8%, 1.0%, and 2.2%, respectively (P cervix.

2017-01-01

BACKGROUND: The development of hip dysplasia is associated with several risk factors. 1 of these risk factors is gender, since 80% of patients with symptomatic hip dysplasia are females. Another risk factor for hip dysplasia is familial predisposition of hip dysplasia. Several studies indicate...... that the risk of hip dysplasia is increased with familial prevalence of hip dysplasia. However, little is known about the association between the familial prevalence and gender and the development of hip dysplasia. PURPOSE: The aim of the study was to estimate the prevalence of hip dysplasia among relatives...... to Danish patients with hip dysplasia operated with periacetabular osteotomy (PAO), and the degree of relationship of affected family members. Furthermore, to assess the association between gender and family predisposition in the same group of patients. METHOD: The study is a cross-sectional study...

Secondary influences and ectopic causes of canine hip dysplasia. Critical constructive thoughts to hip dysplasia diagnostics and to current breeding strategies

This article questions the stagnation of breeding results by hip dysplasia screening and its current etiology. The ''Coxa Valga Antetorta'', anteversion of the hip joint and ''soft tissue displasia'' are discussed besides a multitude of primary diseases leading to growth deformities and other diseases in the hip. Ectopic primary causes like malformation of the spine leading to a secondary ''dysplatic'' osteoarthritis of the hip (functional secondary dysplasia) are also discussed in this article. Recent and very promising breeding strategies (estimation of the breeding value) in the battle against hip dysplasia are presented. Biochemical, immunological and structural aspects are presented as a not totally utopic perspecitive. Molecular genetic markers for hip dysplasia will offer in the near future a possibility to detect carriers ct the disease by a blood sample ion before clinical manifestation

In human genetics and orthopedics quite different answers have been given to the question of hereditary transmission and frequency of hip dysplasia in families of children with congenital hip dislocation. We therefore have made roentgenometric measurements of 110 parents of children with congenital hip dislocation. In 25% we found abnormal flat acetabulae, whereas 12% had pathologic deep hips. This may propose a new concept of morphology of congenital hip dysplasia.

Full Text Available Thanatophoric dysplasia is the lethal skeletal dysplasia characterized by marked underdevelopment of the skeleton and short-limb dwarfism. The child will be having a short neck, narrow thoracic cage and protuberant abdomen. Other anatomical features include a relatively enlarged head with frontal bossing, prominent eyes, hypertelorism and the depressed nasal bridge. The diagnosis is usually made with the ultrasonography in the second trimester. In this study we report a case of this rare entity with emphasis on its anatomical features, abnormalities and clinical profile with relevant review of literature.

Papillary bile duct dysplasia in primary sclerosing cholangitis.

Ludwig, J; Wahlstrom, H E; Batts, K P; Wiesner, R H

1992-06-01

A 62-year-old man with a 20-year history of chronic ulcerative colitis and a 9-year history of primary sclerosing cholangitis (PSC) underwent orthotopic liver transplantation because of symptoms related to PSC and cholangiographic features compatible with a biliary neoplasm. Study of the excised liver revealed papillary mucosal lesions in the common hepatic duct and the right and left hepatic ducts as well as cholangiectases and other features typically associated with PSC. The papillary lesions consisted of abundant fibrovascular stroma covered by biliary epithelium with low-grade and high-grade dysplasia. Some periductal glands were also dysplastic. These features distinguished papillary dysplasia from classic biliary papillomatosis. Only one focus of microinvasion was found; there were no metastases. Among 60 cases of PSC in whom the entire liver could be studied after orthotopic liver transplantation, this was the only instance of unequivocal dysplasia. However, in one specimen, papillary hyperplasia was found. Detailed macroscopic and microscopic rereview of 23 livers from our patients with the longest history of PSC (range, 5-24 years) failed to reveal any additional cases with dysplasia. It is concluded that (a) papillary mucosal lesions in PSC may represent papillary dysplasia without invasion; (b) these lesions may evolve from papillary hyperplasia; (c) the process may be largely, if not entirely, in situ; and (d) the prevalence of dysplasia and carcinoma of bile ducts may be less than the 7%-9% reported in the literature for malignancies associated with PSC.

Full Text Available The rare form of skeletal dysplasia is thanatophoric dysplasia. The meaning for thanatophoric dysplasia is death bearing which is derived from Greek word. It occurs 1in 20,000 to 50,000. It is mainly due to mutations in the fibroblast growth factor receptor 3gene. Features of thanatophoric dysplasia are frontal bossing, prominent eyes, narrow thorax, protruded abdomen and bowed legs. The knowledge about this condition is useful in the fields of Anatomy, Paediatrics, Obstetrics and Gynaecology, Ultrasonagraphy and Genetics, for future research purpose.

Full Text Available The ectodermal dysplasias are congenital, non-progressive and diffuse disorders affecting primarily the tissues derived from ectoderm. Over a period, their classification has become confusing due to indiscriminate use of them “ectodermal dysplasia” for numerous syndromes with a defect in one or more epidermal defect in each element of skin; their precise classification appears difficult as yet. Only X-linked recessive ectodermal dysplasia (Christ-Siemens-Touraine syndrome remains best defined. This paper describes three cases of ectodermal dysplasias highlighting their overlapping features.

1980-07-01

Spondyloepiphyseal dysplasia congenita is a form of primarily short trunk dwarfism, that is manifest at birth but generally has not been regarded as a cause of lethal neonatal dwarfism. Seven neonates with severe dwarfism are presented. The first survived the newborn period, but the other six were early neonatal deaths. All displayed the clinical and radiologic features of spondyloepiphyseal dysplasia congenita. The striking similarities between spondyloepiphyseal dysplasia congenita and achondrogenesis type 2 are discussed.

We report what we think is the first treatment of oral dysplasia with 5% imiquimod cream. A 60-year-old man presented with varying degrees of dysplasia on the soft palate. A cover plate was fabricated and the patient was prescribed 5% imiquimod cream, a topical imunomodulator, for six weeks. The lesion improved and histological examination of an incisional biopsy found no features of dysplasia. This case highlights the efficacy of imiquimod cream in the treatment of dysplasia, and the need for development of a preparation suitable for the oral mucosa. Copyright © 2016.

Ectodermal dysplasia is a rare congenital disease that affects the ectodermal structures. It is characterized by hypotrichosis, hypohidrosis and hypodontia. A 14-year-old boy with ectodermal dysplasia presenting with oligodontia and marked resorption of the maxillary and mandibular alveolar ridges is reported. Prosthetic rehabilitation in the form of a maxillary and mandibular partial denture was made with metal crowns on existing lower teeth to achieve appropriate vertical dimension. Significant improvement in speech, masticatory function and facial esthetics was achieved. Removable prosthodontics can provide an acceptable solution to esthetic, functional and psychological rehabilitation in patients with ectodermal dysplasia.

Oral cancer is one of the most frequent cancers in the world. It arises from epithelial dysplasia. Hence, identifying these lesions in an early stage could prevent their malignant transformation. The aim of the present work was to assess the cell proliferative activity of minichromosome maintenance protein (MCM-2) in oral epithelial dysplastic lesions and to correlate the results with different grades of epithelial dysplasia in an attempt to use MCM-2 in the early detection of malignancy. MCM-2 expression was determined by the nuclear count in a total of 30 oral epithelial dysplastic specimens roughly classified into 10 cases of mild, moderate, and severe dysplasia. Five cases of early invasive squamous-cell carcinomas and 5 cases of epithelial hyperplasia were also included. The MCM-2 immunostaining was found to increase gradually from mild to moderate to severe dysplasia and reached its maximum value in early invasive squamous cell carcinoma. MCM-2 is of prognostic value in cases of oral dysplasia that have a tendency to undergo malignant transformation.

Craniofacial fibrous dysplasia - A review of current management techniques

2012-01-01

Full Text Available Fibrous dysplasia is a pathologic condition of bone of unknown etiology with no apparent familial, hereditary or congenital basis. Lichtenstein first coined the term in 1938 and in 1942 he and Jaffe separated it from other fibro-osseous lesions. It is a bone tumor that, although benign, has the potential to cause significant cosmetic and functional disturbance, particularly in the craniofacial skeleton. Its management poses significant challenges to the surgeon. Craniofacial fibrous dysplasia is 1 of 3 types of fibrous dysplasia that can affect the bones of the craniofacial complex, including the mandible and maxilla. Fibrous dysplasia is a skeletal developmental disorder of the bone-forming mesenchyme that manifests as a defect in osteoblastic differentiation and maturation. It is a lesion of unknown etiology, uncertain pathogenesis, and diverse histopathology. Fibrous dysplasia represents about 2, 5% of all bone tumors and over 7% of all benign tumours. Over the years, we have gained a better understanding of its etiology, clinical behavior, and both surgical and non-surgical treatments.

Rachid, Milene A; Demaula, Christopher D; Scott, Danny W; Miller, William H; Senter, David A; Myers, Sherry

2003-06-01

Recurrent or persistent follicular dysplasia and interface dermatitis are described in nine Boxers. Data on age, sex, seasonality of alopecia and histopathological features of the follicular dysplasia in these nine Boxers are comparable with those described in previous reports. The interface dermatitis was characterized by multifocal annular crusted lesions confined to the areas of follicular dysplasia. The inflammatory lesions were neither pruritic nor painful and affected dogs were otherwise healthy. Histopathologically the clinically inflammatory lesions were characterized as an interface dermatitis. Immunohistochemical studies failed to demonstrate immunoglobulins or complement at the basement membrane zone or within blood vessel walls. In dogs with recurrent or persistent disease, the follicular dysplasia and interface dermatitis ran identical, concurrent courses of spontaneous remission and recurrence, or persistence, respectively. One dog with persistent disease was treated successfully with tetracycline and niacinamide for the interface dermatitis, and melatonin for the follicular dysplasia. Although the aetiopathogenesis of this newly described condition and the relationship between the two histological reaction patterns are not known, photoperiod and genetic predisposition appear to play a role.

Mondini dysplasia

Recent advances in imaging technique, including high resolution thin section computed tomography scanning and magnetic resonance imaging (MRI), permit the easy diagnosis of congenital malformations of the osseous labyrinth, which have so far been lumped together as 'Mondini dysplasia'. In the present study, the anatomic patterns from the radiogrpahic appearance and the clinical manifestation were examined in 18 patients (23 ears) with radiographic abnormalities of the inner ear. The most common abnormal configuration was a large vestibule (20 of 23 ears). This anomaly of the vestibule often involved the lateral semicircular canal, revealed as a round high signal zone on T2-weighted MRI. However, a large vestibule was not always associated with an abnormal cochlea. Abnormal cochleas were found in 8 of the 20 ears with a large vestibule, and most of these 8 ears had total or profound deafness. But 4 of the 10 ears with residual hearing had low tone deafness and 6 had fluctuating hearing loss, which was frequently associated with attacks of dizziness. These clinical manifestations of Mondini dysplasia are similar to those of patients with endolymphatic hydrops. (author)

Sessile serrated adenomas with dysplasia: morphological patterns and correlations with MLH1 immunohistochemistry.

2017-12-01

Sessile serrated adenomas are the precursor polyp of approximately 20% of colorectal carcinomas. Sessile serrated adenomas with dysplasia are rarely encountered and represent an intermediate step to malignant progression, frequently associated with loss of MLH1 expression. Accurate diagnosis of these lesions is important to facilitate appropriate surveillance, particularly because progression from dysplasia to carcinoma can be rapid. The current World Health Organization classification describes two main patterns of dysplasia occurring in sessile serrated adenomas, namely, serrated and conventional. However, this may not adequately reflect the spectrum of changes seen by pathologists in routine practice. Furthermore, subtle patterns of dysplasia that are nevertheless associated with loss of MLH1 expression are not encompassed in this classification. We performed a morphological analysis of 266 sessile serrated adenomas with dysplasia with concurrent MLH1 immunohistochemistry with the aims of better defining the spectrum of dysplasia occurring in these lesions and correlating dysplasia patterns with MLH1 expression. We found that dysplasia can be divided morphologically into four major patterns, comprising minimal deviation (19%), serrated (12%), adenomatous (8%) and not otherwise specified (79%) groups. Minimal deviation dysplasia is defined by minor architectural and cytological changes that typically requires loss of MLH1 immunohistochemical expression to support the diagnosis. Serrated dysplasia and adenomatous dysplasia have distinctive histological features and are less frequently associated with loss of MLH1 expression (13 and 5%, respectively). Finally, dysplasia not otherwise specified encompasses most cases and shows a diverse range of morphological changes that do not fall into the other subgroups and are frequently associated with loss of MLH1 expression (83%). This morphological classification of sessile serrated adenomas with dysplasia may represent an

Full Text Available Bilateral anophthalmia is a rare entity and association with septo-optic dysplasia is an even rare condition. The condition is characterized by absent eyeballs in the presence of eyelids, conjunctiva or lacrimal apparatus. Though anophthalmia can be diagnosed clinically, imaging plays a crucial role in delineating the associated anomalies. In addition, often clinical anophthalmia may prove to be severe microphthalmia on imaging. We describe the imaging findings in an infant with bilateral anophthalmia and septo-optic dysplasia.

Comparison of three methods to diagnose hip dysplasia in dogs

Sharma, Vikas; Mohindroo, J.

2009-01-01

The present study was designed to compare the usefulness of goniometry, radiography and distraction index in diagnosis of hip dysplasia in dogs. During the study 25 clinical cases (50 joints) suspected for hip dysplasia were evaluated. Norberg angle was found to have a significant positive correlation with extension, flexion, abduction, and adduction angles and a significant negative correlation with distraction index (DI) measurements. It could be inferred that all the six parameters (NA, DI, extension, flexion, abduction, and adduction) were reliable indicators for early diagnosis of hip dysplasia.Goniometry could be used as a safe and easy method for preliminary suspicion of hip dysplasia

Full Text Available This paper to describe a case of dysontogenic urethral metaplasia in a one month old mongrel feline who also had bilateral renal dysplasia. Dysontogenic metaplasia in cats are scarce and this change may be associated with renal dysplasia and/or lower urinary tract. The animal had history of abdominal enlargement since birth and dysuria, eliminating urine only dropwise. Due to the poor prognosis we opted for euthanasia. At necropsy was observed enlarged and distended bladder, reduced kidneys and dilated and tortuous ureters. The urethra was thickened, hard to cut, and histologically, was replacing the connective tissue, cartilage and endochondral ossification areas, which features dysontogenic metaplasia. Both kidneys presented primitive appearance featuring dysplasia. Dysontogenic metaplasia in urinary tract feline with renal dysplasia, has not been described.

Adamantinoma, osteofibrous dysplasia and differentiated adamantinoma

International Nuclear Information System (INIS)

Kahn, Leonard B.

2003-01-01

For just over 100 years, adamantinoma has been recognized as a primary bone tumor with epithelial characteristics and predominantly involving the tibia. Osteofibrous dysplasia is a fibro-osseous lesion also predominantly confined to the tibia with radiologic features similar to those of adamantinoma. This lesion has been shown by immunohistochemical studies to frequently contain cytokeratin-positive epithelial cells. More recently, a third group of cases with clinical and radiologic features similar to those of osteofibrous dysplasia have demonstrated more overt strands of epithelial cells within a fibro-osseous background and have been categorized as ''differentiated'', ''regressive'', ''juvenile intracortical'' or ''osteofibrous dysplasia-like'' adamantinoma. Cytokeratin subset immunohistochemical stains and cytogenetic studies performed in recent years suggest a common histogenesis for these three entities. This article reviews the clinical, radiologic and pathologic features of these entities as well as their prognostic significance. It also reviews the results of the immunohistochemical and cytogenetic studies which establish a common histogenetic relationship. (orig.)

Variable manifestations of dysplasia epiphysealis hemimelica

Azouz, E.M.; Slomic, A.M.; Marton, D.; Rigault, P.; Finidori, G.

1985-01-01

Dysplasia epiphysealis hemimelica (DEH) is an osteocartilaginous overgrowth involving one or multiple epiphyses or ossification centers, usually in a lower extremity on one side of the body. Characteristically the involvement is hemimelic, i.e., either the medial or lateral part of the ossification center is involved. The authors have studied 24 patients with DEH and are adding 15 new cases to the literature. Because of the variable manifestations of the dysplasia and its different degrees of involvement in the affected children, they have subdivided it into localized, classical and generalized. In the generalized form, there is involvement of a whole lower extremity from the pelvis to the foot, and some of these patients show megaepiphyses with enlargement of a whole epiphyseal center, not only its medial or lateral part. The authors have also described and illustrated other special features of the dysplasia especially the advanced bone age and the metaphyseal and growth plate involvement.

Full Text Available Fibrous dysplasia (FD is a condition characterized by excessive proliferation of bone forming mesenchymal cells which can affect one bone (monostotic type or multiple bones (polyostotic type. It is predominantly noticed in adolescents and young adults. Fibrous dysplasia affecting the jaws is an uncommon condition. The most commonly affected facial bone is the maxilla, with facial asymmetry being the chief complaint. The lesion in many instances is confused with ossifying fibroma (OF. Diagnosis of these two lesions has to be done based on clinical, radiographic, and microscopic findings. Here, we present a case of fibrous dysplasia of maxilla in a nine-year-old boy mimicking juvenile ossifying fibroma.

Ectodermal dysplasia and sickle cell anaemia are inherited disorders that affect, respectively, the tissues derived from the embryonic ectoderm and the production of erythrocytes by the bone marrow. The simultaneous occurrence of both disorders is extremely rare. This is a case of both ectodermal dysplasia and sickle cell anaemia reported in a 6-year-old. The patient had been diagnosed with sickle cell anaemia for only six months when he sought treatment presenting with the following: hypotrichosis, dry skin, periocular hyperpigmentation, protruding lips, hypodontia, and morphologically altered teeth. The clinical features combined with his medical history led to the diagnosis of ectodermal dysplasia. Dentists should be prepared to recognise patterns that escape normality to aid in the diagnosis of systemic changes, even in patients with other previous diagnoses.

2005-01-01

Cleidocranial dysplasia is a rare, autosomal dominant congenital disorder. A 12-year-old female visited with chief complaint of unerupted permanent teeth. Also her father showed severe class III malocclusion. The extraoral radiography and computed tomography showed delayed closure of the cranial sutures and underdevelopment of maxilla, maxillary sinuses, and frontal sinus. Both clavicles were underdeveloped and thoracic rib cage was bell-shaped. Both zygomatic process appeared as hypoplastic feature. There were many unerupted permanent and supernumerary teeth in the maxilla and mandible. We examined location and number of the unerupted teeth using 3D CT. Finally we could conclude this case was cleidocranial dysplasia based on the clinico-radiologic findings.

Focal cemento-osseous dysplasia (FCOD) is a benign fibroosseous condition that can be seen in dentulous and edentulous patients. It is an asymptomatic lesion and needs no treatment; however, follow-up is essential due to the possibility that it can progress to a condition called florid cemento-osseous dysplasia. We report a case of FCOD of mandible in a 25-year-old female. Clinically, the lesion resembled periapical pathosis of odontogenic origin. An attempt has been made to discuss the clinical and histopathologic features along with differential diagnosis of cemento-osseous dysplasia.

Is There a Relationship between Ovarian Epithelial Dysplasia and Infertility?

Directory of Open Access Journals (Sweden)

Gautier Chene

2012-01-01

Full Text Available Aim. Ovarian epithelial dysplasia was initially described in material from prophylactic oophorectomies performed in patients at genetic risk of ovarian cancer. Similar histopathological abnormalities have been revealed after ovulation stimulation. Since infertility is also a risk factor for ovarian neoplasia, the aim of this study was to study the relationship between infertility and ovarian dysplasia. Methods. We blindly reviewed 127 histopathological slides of adnexectomies or ovarian cystectomies according to three groups—an exposed group to ovulation induction (n = 30, an infertile group without stimulation (n = 35, and a spontaneously fertile control group (n = 62—in order to design an eleven histopathological criteria scoring system. Results. The ovarian dysplasia score was significantly higher in exposed group whereas dysplasia score was low in infertile and control groups (resp., 8.21 in exposed group, 3.69 for infertile patients, and 3.62 for the controls. In the subgroup with refractory infertility there was a trend towards a more severe dysplasia score (8.53 in ovulation induction group and 5.1 in infertile group. Conclusion. These results raise questions as to the responsibility of drugs used to induce ovulation and/or infertility itself in the genesis of ovarian epithelial dysplasia.

Assessment of hip dysplasia and osteoarthritis: Variability of different methods

Troelsen, Anders; Elmengaard, Brian; Soeballe, Kjeld; Roemer, Lone; Kring, Soeren

2010-01-01

Background: Reliable assessment of hip dysplasia and osteoarthritis is crucial in young adults who may benefit from joint-preserving surgery. Purpose: To investigate the variability of different methods for diagnostic assessment of hip dysplasia and osteoarthritis. Material and Methods: By each of four observers, two assessments were done by vision and two by angle construction. For both methods, the intra- and interobserver variability of center-edge and acetabular index angle assessment were analyzed. The observers' ability to diagnose hip dysplasia and osteoarthritis were assessed. All measures were compared to those made on computed tomography scan. Results: Intra- and interobserver variability of angle assessment was less when angles were drawn compared with assessment by vision, and the observers' ability to diagnose hip dysplasia improved when angles were drawn. Assessment of osteoarthritis in general showed poor agreement with findings on computed tomography scan. Conclusion: We recommend that angles always should be drawn for assessment of hip dysplasia on pelvic radiographs. Given the inherent variability of diagnostic assessment of hip dysplasia, a computed tomography scan could be considered in patients with relevant hip symptoms and a center-edge angle between 20 deg and 30 deg. Osteoarthritis should be assessed by measuring the joint space width or by classifying the Toennis grade as either 0-1 or 2-3

Takamine, Yuji; Field, Fiona M.; Lachman, Ralph S.; Rimoin, David L.

2004-01-01

Occipital projections of the cranium have been reported in a number of skeletal dysplasias and syndromes. We observed two cases of atelosteogenesis type I with a bony occipital projection. This finding has neither been noted nor reported in any form of atelosteogenesis. This led us to search the International Skeletal Dysplasia Registry for occipital projections, and we found them in four other syndromes in which they had not been reported. Thus occipital spurs are a non-diagnostic feature that can be found in at least ten distinct disorders as well as a normal variant. (orig.)

Canine hip dysplasia: significance of early bony spurring

International Nuclear Information System (INIS)

Morgan, J.P.

1987-01-01

It is the purpose of this study to call attention to new bone production that often occurs early in the sequence of pathological changes associated with canine hip dysplasia. New bone production extending to bony remodeling, as well as femoral head subluxation, both occur in the sequence of pathologic changes associated with canine hip dysplasia. Subluxation is considered primary, while osteoarthrosis is a secondary feature, and both are used in the diagnosis of canine hip dysplasia. This report concerns the significance of the presence of a solitary bony osteophyte, or spur, that is frequently evident on the caudal aspect of the femoral neck as viewed on the conventional ventrodorsal projection. This report utilizes findings from pelvic radiographs of 605 dogs (five breeds). There was a greater frequency (54%)of this bony change in cases diagnosed radiographically as dysplastic than in cases diagnosed as normal(15%).Thus, it is suggested that this minimal radiographic change can be used as an indicator of early canine hip dysplasia, especially in the absence of subluxation of the femoral head

Patellofemoral dysplasia is a major predisposing factor for instability of the patellofemoral joint. However, there is no consensus as to whether patellofemoral dysplasia is genetic in origin, caused by imbalanced forces producing maltracking and remodelling of the trochlea during infancy and growth, or due to other unknown and unexplored factors. The biomechanical effects of patellofemoral dysplasia on patellar stability and on surgical procedures have not been fully investigated. Also, different anatomical and demographic risk factors have been suggested, in an attempt to identify the recurrent dislocators. Therefore, a comprehensive evaluation of all the radiographic, MRI and CT parameters can help the clinician to assess patients with primary and recurrent patellar dislocation and guide management. Patellofemoral dysplasia still represents an extremely challenging condition to manage. Its controversial aetiology and its complex biomechanical behaviour continue to pose more questions than answers to the research community, which reflects the lack of universally accepted guidelines for the correct treatment. However, due to the complexity of this condition, an extremely personalised approach should be reserved for each patient, in considering and addressing the anatomical abnormalities responsible for the symptoms.

A six-month-old Rhodesian ridgeback dog was presented for evaluation of facial swelling. Chronic renal failure was clinically diagnosed based on urinalysis, biochemical changes and ultrasonography. The facial swelling was due to fibrous osteodystrophy, which was evident on survey radiographs of the skull. On post mortem examination, chronic renal failure as a result of renal dysplasia was confirmed. This is the first reported case of renal dysplasia in this breed of dog

Cemento-osseous dysplasia in Jamaica: review of six cases.

Ogunsalu, C; Miles, D

2005-09-01

Six cases of cemento-osseous dysplasia (COD) of the jaw bone in Jamaicans are reviewed. Five were documented over a 15-year period (1980-1995). These include a case of florid cemento-osseous dysplasia (previously called gigantiform cementoma). Three of the initial cases were histologically diagnosed as gigantiform cementoma. There was no indication in the patient's case file whether these were familial or non-familial. The other two cases were diagnosed histologically as periapical cemento-osseous dysplasia and cementoblastoma respectively. Based on the current understanding of the nature of florid-cemento-osseous dysplasia (FLCOD), a new case was diagnosed as such solely on radiological findings. This single case of FLCOD is reported and discussed against the background of other cemento-osseous lesions. Special emphasis is placed on the radiology of COD in this paper. The confirmative role of radiology without the need for histophathology and treatment for asymptomatic FLCOD is emphasized.

Sharma, B.G.

2003-01-01

A new type of rare bone dysplasia is described, which shares some common features with spondylo-meta-epiphyseal dysplasia: short limb-abnormal calcification type and lethal metatropic dysplasia. Besides these features, the present case has some additional unusual features. Facial malformation was very obvious and of a different type. The nose and nares were completely flattened. Hypertrophied acetabular bones, round densities on the ilia, premature ossification of many epiphyses and carpal bones, curvilinear calcifications in some joints, fusion of the ischiopubic rami, calcification of many costal cartilages and thick sclerotic base of the skull were a few of the significant findings. On the basis of the clinical and radiological features, the condition has been named ''spondylo-epi-metaphyseal dysplasia: mixed type''. (orig.)

Choi, Karp Shik [Dept. of Dental Radiology, College of Dentistry, Kyungpook National University, Daegu (Korea, Republic of)

1999-02-15

The author observed and compared the radiographic features of 49 cases of the fibrous dysplasia and 14 cases of the ossifying fibroma in the osteoblastic or mature stage radiologically and histopathologically. The obtained results were as follows: 1. Fibrous dysplasia occurred most frequently in the 2nd decade, but ossifying fibroma in the 3rd and 4th decades, and both lesions occurred with slight predilection in females. 2. In most cases, chief complaints were painless facial swelling. And 61.1% of fibrous dysplasia occurred in the maxilla, 92.9% of ossifying fibroma in the mandible, and most of these lesions occurred in the premolar-molar region. 3. In the mandibular lesions, ossifying fibroma was shown more oval and round shape, but fibrous dysplasia was shown fusiform shape. 4. Fibrous dysplasia was shown homogeneously distributed, complete radiopaque shadow at 63%, and ossifying fibroma was shown concentric, mixed appearance of radiolucent and radiopaque shadow at 92.9%. 5. Fibrous dysplasia was entirely shown poorly outlined and blended to normal surrounding bone, but ossifying fibroma was shown well-defined border. 6. Cortical thinning and expansion were observed in these lesions, but degree of cortical expansion was more severe in ossifying fibroma than fibrous dysplasia. 7. Loss of lamina dura, tooth displacement, and displacement of mandibular canal were observed in both lesions, but root resorption was observed in ossifying fibroma only.

Aim: To prove that bilateral hereditary micro-epiphyseal dysplasia (BHMED), first described by Elsbach in 1959, is a distinct disorder radiologically as well as clinically, compared with multiple epiphyseal dysplasia (MED). Material and Methods: We used the data of the revised pedigree with 84 family members, performed a medical history, physical examination and made a radiological evaluation for defining a clinical and radiological phenotype of BHMED family members. We used blood samples for genetic analysis. Results: Although there is a clear clinical picture of the dysplasia, the radiological signs are more reliable for making the diagnosis. Especially the typical deformity of the hip and knee joint are diagnostic for BHMED. By linkage analysis we excluded linkage with the three known MED-loci (EDM1, EDM2 and EDM3). Conclusion: BHMED is indeed an entity that is distinct from common multiple epiphyseal dysplasia (MED), clinically, as well as radiologically and genetically. (orig.) [German] Ziel: Es sollte dargelegt werden, dass sich eine vererbliche, laterale Mikro-Epiphysendysplasie (BHMED), Erstbeschreibung durch Elsbach 1959, klinisch, radiologisch und genetisch von einer mutiplen Epiphysendysplasie (MED) unterscheidet. Material und Methode: Anhand der Daten eines ueberarbeiteten Stammbaumes mit 84 Familienmitgliedern wurde der medizinische Werdegang rekonstruiert. Es erfolgte eine physische Untersuchung der Familienmitglieder. Schliesslich wurde eine radiologische Auswertung durchgefuehrt, um einen klinischen und radiologischen Phaenotyp der von BHMED betroffenen Familienmitglieder zu definieren. Fuer eine genetische Analyse wurden Blutproben entnommen. Ergebnisse: Obwohl es ein deutliches klinisches Bild einer Dysplasie gibt, sind die radiologischen Kennzeichen fuer die Diagnose zuverlaessiger. Insbesondere die typische Deformation der Huefte und des Kniegelenks ist diagnostisch fuer BHMED. Durch Linkage-Analyse konnte eine Verbindung zu den drei bekannten

Background: Reliable assessment of hip dysplasia and osteoarthritis is crucial in young adults who may benefit from joint-preserving surgery. Purpose: To investigate the variability of different methods for diagnostic assessment of hip dysplasia and osteoarthritis. Material and Methods: By each of four observers, two assessments were done by vision and two by angle construction. For both methods, the intra- and interobserver variability of center-edge and acetabular index angle assessment were analyzed. The observers' ability to diagnose hip dysplasia and osteoarthritis were assessed. All measures were compared to those made on computed tomography scan. Results: Intra- and interobserver variability of angle assessment was less when angles were drawn compared with assessment by vision, and the observers' ability to diagnose hip dysplasia improved when angles were drawn. Assessment of osteoarthritis in general showed poor agreement with findings on computed tomography scan. Conclusion: We recommend that angles always should be drawn for assessment of hip dysplasia on pelvic radiographs. Given the inherent variability of diagnostic assessment of hip dysplasia, a computed tomography scan could be considered in patients with relevant hip symptoms and a center-edge angle between 20 deg and 30 deg. Osteoarthritis should be assessed by measuring the joint space width or by classifying the Toennis grade as either 0-1 or 2-3

This paper describes a clinical case of a male with hypohidrotic ectodermal dysplasia submitted to rehabilitation and occlusal dental interventions with follow-up from 3 to 14 years of age. Due to the severe effects on function and esthetics, the clinical manifestations of ectodermal dysplasia exert a negative impact on quality of life. However, oral rehabilitation in childhood poses a challenge due to growth and development. A male with hypohidrotic ectodermal dysplasia began dental intervention at the age of 3 years. The clinical and radiographic exams revealed the absence of several primary and permanent teeth and abnormal shape of the primary maxillary incisors. The facial characteristics were compatible with hypohidrotic ectodermal dysplasia, such as a prominent brow, everted lips, fattened bridge of the nose and small vertical facial height. The treatment proposed involved rehabilitation through successive temporary partial dentures, functional orthopedics of the jaws, esthetic reconstruction of the anterior teeth, timely occlusal intervention and preventive actions for the control of dental caries and plaque. The present case demonstrates that early care plays a fundamental role in minimizing the biopsychosocial consequences of hypohidrotic ectodermal dysplasia and preparing the patient for future oral rehabilitation. Although, the literature offers a number of papers describing dental treatment for ectodermal dysplasia, few cases include long-term follow-up and the use of a functional orthopedic appliance in combination with removable dentures in such patients.

Ectodermal dysplasia is a hereditary disease characterized by congenital dysplasia of one or more ectodermal structure and other accessory appendages. The oral manifestations are anodontia and poor bony foundation which impairs both esthetic as well as the masticatory function. The prosthodontic management of patients with such dysplastic condition necessitates a multidisciplinary approach. This case report describes the prosthodontic oral rehabilitation of a 16 years old female pediatric patient with ectodermal dysplasia. How to cite this article: Singh T, Singh R, Singh GP, Singh JP.

Odonto-onycho-dermal dysplasia (OODD) is a rare form of ectodermal dysplasia characterized by severe oligodontia, onychodysplasia, palmoplantar hyperkeratosis, dry skin, hypotrichosis, and hyperhidrosis of the palms and soles. The ectodermal dysplasias resulting from biallelic mutations in the WNT10A gene result in highly variable phenotypes, ranging from isolated tooth agenesis to OODD and Schöpf-Schulz-Passarge syndrome (SSPS). We identified a female patient, with consanguineous parents, who was clinically diagnosed with OODD. Genetic testing showed that she was homozygous for a previously reported pathogenic mutation in the WNT10A gene, c.321C > A, p.Cys107*. The skin and nail abnormalities were for many years interpreted as psoriasis and treated accordingly. A thorough clinical examination revealed hypotrichosis and hyperhidrosis of the soles and dental examination revealed agenesis of permanent teeth except the two maxillary central incisors. Skin biopsies from the hyperkeratotic palms and soles showed the characteristic changes of eccrine syringofibroadenomatosis, which has been described in patients with ectodermal dysplasias. Together with a family history of tooth anomalies, this lead to the clinical suspicion of a hereditary ectodermal dysplasia. This case illustrates the challenges of diagnosing ectodermal dysplasia like OODD and highlights the relevance of interdisciplinary cooperation in the diagnosis of rare conditions.

Dogs with hip dysplasia are commonly presented to veterinarians for evaluation. Although many causes of the condition have been proposed, a definitive cause has not been established. The multifactorial nature of canine hip dysplasia can confuse client education and management ofthe disease. The basic concept involved is the biomechanical imbalance between the forces on the coxofemoral joint and the associated muscle mass; the result is joint laxity in young, growing dogs. This laxity leads to incongruity; the eventual result is degenerative joint disease. Canine hip dysplasia can affect any breed but is most often reported in large and giant breeds. Understanding the pathophysiology and biomechanics involved with this developmental disease is important in providing clients with diagnostic, therapeutic, and prognostic information. The selection of treatment is influenced by the following factors:the age, health, and intended use of the patient; clinical signs; diagnostic findings; the availability of treatment; and the financial constraints of the owner. This article discusses the current concepts concerning the pathophysiology and biomechanics of canine hip dysplasia and outlines diagnostic and therapeutic options. The objective of the article is to provide practitioners with a reference for decision making and client education

Cleidocranial dysplasia is a rare and autosomal dominant disorder characterized by aplasia or hypoplasia of the clavicles, an open fontanelle, dental abnormalities, and short stature. A 17-year-old female who presented with short stature and subsequent delay in eruption of permanent teeth is described. she showed the abnormal hypermobility of the shoulder, ocular hypertelorism and concave nasal bridge. Radiographs revealed the underdeveloped maxilla, defect of the cranium in the fontanelle region, and aplasia of the clavicles. Characteristically, panoramic view revealed near parallel-sided borders of the ascending ramus and downward curvature of the zygomatic arch with hypoplasia. The prolonged retention of deciduous teeth with delayed eruption of permanent teeth and multiple embedded supernumerary teeth were striking. Radiographic and clinical investigations revealed Cleidocranial dysplasia.

This article aims to report a case of known ectrodactyly ectodermal dysplasia in a young male patient who subsequently was found to have a retinal tear and localized retinal detachment. This is a case report of a 22-year-old white male patient with a history of ectrodactyly ectodermal dysplasia. Our patient initially presented with an acute exacerbation of bilateral, red, irritated eyes. No recent changes in vision were reported. The patient's ocular surface disease was consistent with ectrodermal dysplasia syndrome. However, a dilated fundus examination revealed an asymptomatic retinal tear with a surrounding localized retinal detachment. In this case, the patient presented with longstanding ocular surface disease known to be associated with this patient's inherited ectoderm disorder. In addition, this patient revealed a retinal tear, raising the possibility that patients with inherited congenital ectodermal dysplasia could be at risk for damaged structures originating from the neural ectoderm. In this heterogeneous disease, we are contributing to the existing literature a case of ectodermal dysplasia syndrome with obvious ectodermal complications that also had retinal findings leading us to speculate question if neural ectoderm could also be involved in this inherited disease.

Tricho-odonto-onycho-dermal dysplasia and WNT10A mutations.

We report on three novel (IVS2+1G>A splice site, c.1066G>T, and c.1039G>T, and one previously reported (c.637G>A) WNT10A mutations in three patients affected with odonto-onycho-dermal dysplasia (OODD; OMIM 275980). OODD is a rare form of autosomal recessive ectodermal dysplasia involving hair, teeth, nails, and skin, characterized by hypodontia (tooth agenesis), smooth tongue with marked reduction of filiform and fungiform papillae, nail dysplasia, dry skin, palmoplantar keratoderma, and hyperhidrosis of palms and soles. The novel IVS+1G>A splice site mutation is predicted to cause significant protein alteration. The other novel mutations we found including c.1066G>T and c.1039G>T are predicted to cause p.Gly356Cys and p.Glu347X, respectively. Barrel-shaped mandibular incisors and severe hypodontia appear to be associated with homozygous or compound heterozygous mutations of WNT10A. The name "tricho-odonto-onycho-dermal dysplasia" is suggested to replace "odonto-onycho-dermal dysplasia" because hair anomalies including hypotrichosis and slow-growing hair have been reported in numerous reported patients with this syndrome. © 2014 Wiley Periodicals, Inc.

Fibrous dysplasia is believed to be a hamartomatous developmental lesion of unknown origin. This disease is divided into monostotic and polyostotic fibrous dysplasia. Polyostotic type can be divided into craniofacial type, Lichtenstein-Jaffe type, and McCune-Albright syndrome. In this case, a 31-year-old female presented spontaneous loss of right mandibular teeth before 5 years and has shown continuous expansion of right mandibular alveolus. Through the radiographic view, the coarse pattern of the mixed radiopaque-lucent lesion was seen on the right mandibular body, and there was diffuse pattern of the mixed radiopaque-lucent lesion with ill-defined margin in the left mandibular body. In the right calvarium, the lesion had cotton-wool appearance. Partial excision for contouring, multiple extraction, and alveoloplasty were accomplished under general anesthesia for supportive treatment. Finally we could conclude this case was polyostotic fibrous dysplasia of cranio-maxillofacial area based on the clinical, radiologic finding, and histopathologic examination.

Cortical dysplasia is the most common cause of pediatric refractory epilepsy. MRI detection of epileptogenic lesion is associated with good postsurgical outcome. Additional electrophysiological information is suggested to be helpful in localization of cortical dysplasia. Educational measures were taken to increase the awareness of cortical dysplasia at our institution in the context of a recent International League Against Epilepsy (ILAE 2011) classification of cortical dysplasia. To determine changes in the rate of prospective identification of cortical dysplasia on an initial radiology report and also evaluate the benefit of MRI review as part of a multidisciplinary epilepsy conference in identifying previously overlooked MRI findings. We retrospectively evaluated surgically treated children with refractory epilepsy from 2007 to 2014 with cortical dysplasia on histopathology. We analyzed the initial radiology report, preoperative MRI interpretation at multidisciplinary epilepsy conference and subsequent retrospective MRI review with knowledge of the resection site. We recorded additional electrophysiological data and the presence of lobar concordance with the MRI findings. Of 78 children (44 MRI lesional) evaluated, 18 had initially overlooked MRI findings. Comparing 2007-2010 to 2011-2014, there was improvement in the rate of overlooked findings on the initial radiology report (54% vs. 13% of lesional cases, respectively; P = 0.008). The majority (72%) were identified at a multidisciplinary conference with lobar concordance of findings with at least one additional electrophysiological investigation in 89%. Awareness of current classification schemes of cortical dysplasia and image review in the context of a multidisciplinary conference can lead to improved MRI detection of cortical dysplasia in children.

We retrospectively evaluated surgically treated children with refractory epilepsy from 2007 to 2014 with cortical dysplasia on histopathology. We analyzed the initial radiology report, preoperative MRI interpretation at multidisciplinary epilepsy conference and subsequent retrospective MRI review with knowledge of the resection site. We recorded additional electrophysiological data and the presence of lobar concordance with the MRI findings. Of 78 children (44 MRI lesional) evaluated, 18 had initially overlooked MRI findings. Comparing 2007-2010 to 2011-2014, there was improvement in the rate of overlooked findings on the initial radiology report (54% vs. 13% of lesional cases, respectively; P = 0.008). The majority (72%) were identified at a multidisciplinary conference with lobar concordance of findings with at least one additional electrophysiological investigation in 89%. Awareness of current classification schemes of cortical dysplasia and image review in the context of a multidisciplinary conference can lead to improved MRI detection of cortical dysplasia in children.

We report a family in which two sibs have both achondroplasia and pseudoachondroplastic dysplasia. The mother has achondroplasia and the father has pseudoachondroplastic dysplasia, which he had inherited from his father. Both children appeared typical of achondroplasia at birth. By 1 1/2 years they had developed a fixed lumbar kyphosis with gibbus and had additional x ray changes unusual for just achondroplasia and suggestive of pseudoachondroplastic dysplasia. Subsequently both children have...

Cho, Su Beom; Koh, Kwang Joon

1995-01-01

Few cases of florid osseous dysplasia has been described as a condition that characteristically affects the jaws. It usually manifests as multiple radiopaque masses distributed throughout the jaws. Confusion exists about the relationship of florid osseous dysplasia, gigantiform cementoma, chronic sclerosing osteomyelitis, sclerosing osteitis or multiple enostosis. Authors experienced a case of florid osseous dysplasia of the jaws in 52-year-old female on the basis of clinical, radiographic and histopathologic findings. The characteristic features are as follows: 1. In clinical examination, there was no clinical sign and symptoms except extrated area. And there was no facial asymmetry. 2. Radiograms show round or lobular dense radiopaque masses surrounded by radiolucent bands in lower molar teeth area bilaterally. And slight increased radiopacities in maxillary molar teeth area bilaterllay. There was no expansion or thinning of buccal and lingual cortical bones. There is no displacement or resorption of involved teeth. In right side of mandible, mandibular canal is displaced inferiorly due to mass. 3. Photomicrograms show densely mineralized sclerotic acellular masses with empty lacunae. Pattern is suggestive of cementum, although it could be considered sclerotic bone. In the periphery, lesion consisting of moderately cellular fibrous tissue in calcified products are deposited.

Callea, Michele; Vinciguerra, Agatino; Willoughby, Colin E; Deroma, Laura; Clarich, Gabriella

2013-01-01

Ectodermal dysplasia is a rare disease which affects at least two ectodermal-derived structures such as hair, nails, skin, sweat glands and teeth. Approximately 200 different conditions have been classified as an ectodermal dysplasia and X-linked hypohidrotic ectodermal dysplasia (XHED) represents the commonest form. Clinically, XHED is characterized by hypotrichosis, hypohidrosis and hypodontia. A variety of ocular manifestations have been reported in XHED, the most common being dryness of eyes due to tear deficiency and instability of the film secondary to the absence of meibomian gland function. Here we report a child with the distinctive clinical features of XHED confirmed with molecular diagnosis who presented with infantile bilateral glaucoma, in addition to the classical ocular involvement in XHED.

Human papilloma virus infection and cervical dysplasia.

2012-01-01

Pap testing is considered to be the best screening tool for cervical cancer but there is currently great interest in the possible application of human papilloma virus (HPV) testing to supplement Pap screening for cervical cancer. To determine the prevalence of high-risk HPV types in the studied population and to explore the association between high-risk HPV types and cervical dysplasia. Cross-sectional study conducted at the Iasi Cuza Voda Obstetrics-Gynecology Hospital and Suceava County Hospital. 332 women who underwent colposcopy for cervical lesions between 2006 and 2011 were included in this study. The overall prevalence of HPV was 57.23%. HPV prevalence differs significantly in the three age groups up to 50 years. It was highest in patients below the age of 40 and progressively lower with advancing age. The overall prevalence of cervical dysplasia was 56.62%. The prevalence of cervical dysplasia was highest in the age groups up to 40 years. The most important determinant of HPV infection is age. Persistence of HPV appears to be associated with progression to squamous intraepithelial lesion. Dysplasia is often missed in a cervical sample either because of human error in screening and interpretation, or because of suboptimal quality of Pap smear. Incorporation of HPV testing into the present Pap screening program has the potential of making screening for cervical cancer more effective, and a necessary prelude to assessing this is by determining the prevalence of the high-risk types.

Bronchopulmonary dysplasia is the most common sequelae related to very low birth weight infants, mostly with those of extremely low birth weight. Even with advances in prevention and treatment of respiratory distress syndrome associated with prematurity, there is still no decrease in the incidence in this population, although a change in its clinical expression and severity has been observed. There are, however, differences in its frequency between health centres, probably due to a non-homogeneously used clinical definition. In this article, the Committee of Standards of the Spanish Society of Neonatology wishes to review the current diagnosis criteria of bronchopulmonary dysplasia to reduce, as much as possible, these inter-centre differences.

Chung, Gyung Ho; Lee, Sang Yong; Kim, Chong So; Kim, Young Kon; Lee, Young Hwan; Jeong, Su Hyun

2002-01-01

To describe curved planar reconstruction imaging (CPR) and determine its usefulness in the evaluation of focal cortical dysplasia of the brain. In 17 cases of focal cortical dysplasia (cortical dysplasia (n=9), schizencephaly (n=5), and heterotopia (n=3), CPR images were created using a multiplanar reconstruction program and imaging data obtained during T1 magnetization prepared rapid acquisition gradient-echo MR imaging. We assessed the precise configuration of abnormalities and their relation to adjacent gyri and sulci. CPRI showed the brain cortex as a 2D panoramic image, demonstrating the precise configurations and locations of dysplasia-associated abnormalities and their relation to adjacent gyri and sulci, and the precise shape of the gray-white matter interface. CPRI can provide important radiological information about the extension and configuration of focal cortical dysplasia, and its relation to neighboring cortical structures. We believe that CPRI should form an essential part of the routine investigation os suspected cases of focal cortical dysplasia

MR urography has the potential to significantly improve our understanding of the relationship between reflux nephropathy, pyelonephritis, vesicoureteric reflux and renal dysplasia. MR urography utilizes multiple parameters to assess both renal anatomy and function and provides a more complete characterization of acquired and congenital disease. Pyelonephritis and renal scarring can be distinguished by assessing the parenchymal contours and signal intensity. Characteristic imaging features of renal dysplasia include small size, subcortical cysts, disorganized architecture, decreased and patchy contrast enhancement as well as a dysmorphic pelvicalyceal system. Because of its ability to subdivide and categorize this heterogeneous group of disorders, it seems inevitable that MR urography will replace DMSA renal scintigraphy as the gold standard for assessment of pyelonephritis and renal scarring. MR urography will contribute to our understanding of renal dysplasia and its relationship to reflux nephropathy. (orig.)

Rasmussen's encephalitis is a rare syndrome characterized by intractable seizures, often associated with epilepsia partialis continua and symptoms of progressive hemispheric dysfunction. Seizures are usually the hallmark of presentation, but antiepileptic drug treatment fails in most patients and is ineffective against epilepsia partialis continua, which often requires surgical intervention. Co-occurrence of focal cortical dysplasia has only rarely been described and may have implications regarding pathophysiology and management. We describe a rare case of dual pathology of Rasmussen's encephalitis presenting as a focal cortical dysplasia (FCD) and discuss the literature on this topic. PMID:25667877

Kim, Kyung Soo; Lee, Sang Wook; Cho, Young Jun; Kim, Young Sook

1983-01-01

Fibrous dysplasia of bone is a skeletal development anomaly of unknown etiology characterized by single or multiple areas of fibrous tissue replacement of medullary cavity of one or more bones. The disease may be localized to single bone (monostotic form) or may affect multiple bones (polyostotic form). Eighteen cases of fibrous dysplasia diagnosed by roentgenlogic or histologic assessment at Chosun University Hospital, Chosun University Hospital and Kwangju Christian Hospital during recent ten tears were analyzed clinically and radiologically. The results were as follows: 1. 16 case of them had monostotic involvement, and 2 cases showed polyostotic disease, but none of our series presented Albright's syndrome. 2. The male to female ratio in this series was 10 : 8, but then 2 polyostotic forms of them were females. In age distribution, peak incidence at the time of diagnosis was in the age group of second decade (10 cases). 3. Maxilla (6 cases) and femur (4 case) were frequently involved sites in patients with monostotic lesion, whereas polyostotic lesions diffusely affected skull, pelvis, ribs and limb bones. 4. The clinical symptoms according to the extent and site of disease were very variable, which were localized painless or painful swelling, nasal obstruction, deformity of face or extremity and incidentally during routine roentgen study. 5. The chemical abnormality of blood serum was moderate degree of elevated serum alkaline phosphatase in only one patients with monostotic lesion. 6. The main radiologic findings of fibrous dysplasia were relatively well circumscribed single or multiloculated cystilike appearance, bone expansion, cortical thinning and/or erosion, bony deformity and pathologic fracture, but especially in maxilla, dense homogenous area with expanding lesion was observed in our series

Recent studies have emphasized the role of podoplanin in oral lesions at risk of malignant transformation. We investigated a group of oral leukoplakias (OLs) to determine a possible relation between altered podoplanin expression and dysplasia, and to compare the results with those obtained by other, widely used biomarkers. The population consisted of 40 consecutive patients with a clinical and histological diagnosis of OL. Thirty-two OLs did not show dysplasia, whereas eight lesions presented with dysplasia. Immunohistochemical expression of podoplanin, p53 and Ki67 was analyzed in all samples. All three biomarkers were positive in seven of eight dysplastic OLs. Among the 32 OLs without dysplasia, Ki67 and p53 showed positive values in 21 and 10 samples respectively, whereas podoplanin was positive in only one case. Multiple logistic regression showed that podoplanin was the most powerful variable (Chi square 9.77; p < .01) statistically related to the presence of dysplasia. In addition, podoplanin showed a higher specificity value (96.87%) than Ki67 (34.37%) and p53 (68.75%). Podoplanin seems to be a reliable means of discriminating lesions with epithelial dysplasia and could be introduced in routine practice as a marker to discriminate OLs at risk of developing cancer.

Recent advances in MRI have revealed congenital brain malformations and subtle developmental abnormalities of the cerebral and cerebellar cortical architecture. Typical cerebellar cortical dysplasia as a newly categorized cerebellar malformation, has been seen in patients with Fukuyama congenital muscular dystrophy. Cerebellar cortical dysplasia occurs at the embryonic stage and is often observed in healthy newborns. It is also incidentally and initially detected in adults without symptoms. To the best of our knowledge, cerebellar dysplasia without any related disorders is very rare. We describe the MRI findings in one patient with disorganized foliation of both cerebellar hemispheres without a related disorder or syndrome

Bagley, R.S.; Harrington, M.L.; Tucker, R.L.; Sande, R.D.; Root, C.R.; Kramer, R.W.

1996-01-01

Occipital dysplasia was found in association with cervical spinal cord abnormalities in two dogs. One dog presented for tetraparesis and cervical hyperesthesia, the other for historical cervical hyperesthesia and mild paraparesis. In dog 1, a midline cervical spinal cord defect consistent with a communicating syrinx was found. In the other dog, a presumptive syringo/hydromyelia of the cervical spinal cord was found on magnetic resonance imaging. While occipital dysplasia alone is not thought to cause any clinical abnormalities, the dogs of this report suggest that intramedullary central nervous system abnormalities may be present concurrently with occipital dysplasia and should be considered as a possible cause of the clinical signs. The relationship between occipital dysplasia and syringo/hydromyelia in these dogs remains unclear, however, similar associated abnormalities are occasionally found in humans with Chiari malformation

2002-01-01

Objective: To study the characteristics of fibrous dysplasia of bone in bone imaging and evaluate the diagnostic value of radionuclide bone scan in fibrous dysplasia of bone. Methods: All 42 cases of fibrous dysplasia of bone patients had radionuclide bone scan performed and compared with other imaging modalities. A retrospective study method was used to analyze the imaging results. Results: Although fibrous dysplasia of bone showed uptake of 99m Tc-MDP in the images, its appearance characteristic was different from those metastatic bone tumors and other bone diseases. Combining with X rays and other imaging modalities can improve the diagnostic accuracy of this disease. Conclusion: Radionuclide bone scan has got certain value in the diagnosis of fibrous dysplasia of bone. Combining with other imaging modality can make up its disadvantage of low specificity

The transcription factor p63 is critically important for skin development and maintenance. Processes that require p63 include epidermal lineage commitment, epidermal differentiation, cell adhesion, and basement membrane formation. Not surprisingly, alterations in the p63 pathway underlie a subset of ectodermal dysplasias, developmental syndromes in which the skin and skin appendages do not develop normally. This review summarizes the current understanding of the role of p63 in normal development and ectodermal dysplasias. PMID:20445549

Ectodermal dysplasia comprises a group of disorders affecting ectodermal tissues. Severity depends on the genetic aberration; hyperpyrexia secondary to absence of sweat glands is a common complication. Treatment is supportive. This case report describes a 1-month, 27-day-old male infant with a diagnosis of X-linked recessive anhidrotic ectodermal dysplasia. On the day of his death, his mother swaddled him in a blanket and placed him on the couch at 5:30 am. When she picked him up at 8:00 am, he was unresponsive. At the emergency department, his rectal temperature was 40°C. Postmortem blood culture was positive for group B streptococcus, a possible etiology for fever. It is vital to teach parents that close monitoring of children with ectodermal dysplasia is necessary, as an increase in body temperature can become life threatening. © 2014 American Academy of Forensic Sciences.

Reports on perianal atypical leiomyoma, a perianal tumor, are rare. We confirmed a perianal atypical leiomyoma by its clinical presentation, magnetic resonance imaging findings, and immunohistochemistry. A 28-year-old female with a perianal mass found more than 4 years ago. The 5cm_4cm_4cm sized mass was located on the left side of the anus and vagina; The magnetic resonance imaging (MRI) scan revealed: A 4.1cm × 5.2cm × 4.9cm sized round mass was observed on the left side of the circumference. Perianal atypical leiomyoma. anal peripheral mass resection was performed under lumbar anesthesia. The postoperative course was uneventful, healing, the patient was discharged. Perianal atypical leiomyomas are benign tumors, but with the clinically atypical leiomyoma, it is sometimes difficult to distinguish between potential malignant smooth muscle tumors,and there may be malignant changes. Surgery should ensure complete resection, and to avoid postoperative recurrence, there should be a regular follow-up.

Full Text Available Ectodermal dysplasia is a rare hereditary disorder with a characteristic physiognomy. The ectodermal dysplasia constitutes a group of hereditary disorders whose clinical manifestation can be defects in ectodermal structures. The case of a 11-year-old child with hypohidrotic ectodermal dysplasia and partial anodontia is presented. Affected children require extensive dental treatment to restore appearance and help the development of a positive self image. Partial denture was provided to encourage a normal psychological development and to improve the function of the stomatognatic system. It is important for the patient and the dentist to understand that continued monitoring for dental problems is necessary. This paper had an objective to relate and discuss a case of hypohidrotic ectodermal dysplasia, with the approach of the influence of an esthetic rehabilitation and functional alternative in the improvement of the quality of life.

Displasia broncopulmonar Bronchopulmonary dysplasia

2005-04-01

Full Text Available OBJETIVO: Apresentar uma ampla revisão da literatura sobre displasia broncopulmonar, abordando novas definições, fisiopatologia, prevenção, tratamento, prognóstico e evolução. FONTE DOS DADOS: Foram selecionados os artigos mais relevantes sobre o tema, desde a sua descrição inicial, em 1967, pesquisados na MEDLINE. SÍNTESE DOS DADOS: A displasia broncopulmonar é considerada uma das principais causas de doença pulmonar crônica em lactentes. Está associada a hospitalizações freqüentes e prolongadas, especialmente por doenças pulmonares, altos índices de mortalidade e alterações no desenvolvimento neuropsicomotor e no crescimento pôndero-estatural. A patogênese é complexa e influenciada principalmente por prematuridade, infecção, oxigênio suplementar e ventilação mecânica. A prevenção envolve o acompanhamento pré-natal adequado, a prevenção do parto prematuro, o uso pré-natal do corticosteróide, a terapia de reposição de surfactante e o uso de estratégias ventilatórias "protetoras". O tratamento do paciente com displasia broncopulmonar demanda uma equipe multidisciplinar. Quando indicada, a suplementação de oxigênio é de extrema importância. Apesar de maior risco de morbimortalidade nos primeiros anos de vida, a evolução em longo prazo é favorável na maioria das vezes. CONCLUSÕES: A displasia broncopulmonar vem sendo profundamente estudada na tentativa de identificação das suas causas e possibilidades de prevenção e de tratamento. Ainda existem controvérsias quanto a esses assuntos e também em relação ao prognóstico desses pacientes, especialmente quando se trata da evolução tardia da "nova" displasia broncopulmonar.OBJECTIVE: To present a wide-ranging review of the literature on bronchopulmonary dysplasia, covering new definitions, pathophysiology, prevention, treatment, prognosis and progression.

Zorko, B.; Ivanusa, T.; Pelc, R.

2005-01-01

The aim of the study was to evaluate the effects of progression of CHD and degenerative joint disease on a working capability of population of police working dogs. In the first part of the study, we reviewed the whole health documentation of all dogs and gathered all necessary radiographs of hip joints that were taken at first initial procurement. In the second part, clinical examination and radiographs of all dogs were taken 60 months after first examination and the progression of hip dysplasia was evaluated by the FCI scheme. All dogs were male, 35 German shepherds and 5 Rottweilers. The Norberg-Olsson angle in the first set of radiographs was 105.54 +/- 3.22 deg in 37 dogs without hip dysplasia and 100.17 +/- 2.99 deg in 3 dogs with initial mild dysplasia. In the second set of radiographs taken after 60 months of service the Norberg- Olsson angle was 105.60 +/- 3.67 deg in 23 dogs with no signs of hip dysplasia and 101.62 +/- 4.49 deg in 17 dogs with hip dysplasia. On the first set of radiographs, secondary degenerative changes were found in 3 dogs with initial mild dysplasia (7.5 %) and in 14 dogs (35 %) on second radiographs. The position of the centre of the femoral head on first radiographs was outside of dorsal acetabular rim in 25 (31.25 %) of estimated hip joints (n = 80); at the level of the rim in 30 (37.5 %) and inside in 25 (31.25 %). On second radiographs it was outside in 41 (51.25 %); at the level of the rim in 26 (32.5 %); and inside in 13 (31.25 %) of estimated hip joints. The mean femoral angle of inclination for all 40 dogs was 132.50 +/- 4.39? deg . If it has occured, the increase in degree of hip dysplasia was generally more than one degree. In 57.5 % of cases hip dysplasia was not determined on second radiographs. All dogs with some degree of hip dysplasia were German shepherds, but only one of them had clinical symptoms connected to CHD. The progression of hip dysplasia did not correlate with work period of the dogs, and has no influence on

Wozniak, Rachel A F; Gonzalez, Mithra; Aquavella, James V

2016-07-01

To describe the complex surgical management and novel medical approach for a keratoprosthesis (KPro Boston type I) in a monocular, 73-year-old patient with ectodermal dysplasia and chronic, noninfectious corneal necrosis. Best-corrected visual acuity (BCVA) was measured with Snellen letters. Surgical intervention included an amniotic membrane graft, complete replacement of the KPro, conjunctival flap graft, corneal donor tissue grafts combined with inferior rectus muscle advancement, periosteal tissue graft, tarso-conjunctival flap construction, and symblepharolysis. Infliximab was used as a medical adjunctive therapy. Initial KPro placement provided a BCVA of 20/25 and long-term stability. Subsequent chronic melting at the optic border necessitated numerous surgeries to prevent extrusion and failure. Ultimate fistulization was addressed with the formation of a surgical pocket. The addition of infliximab promoted ocular surface stability, and the patient has maintained a BCVA of 20/80. Ectodermal dysplasia can result in eyelid and corneal abnormalities, requiring a KPro for visual restoration. In the setting of chronic, sterile corneal melt, novel surgical approaches and the off-label use of infliximab allowed for visual rehabilitation.

Cabrera, M.N.B.; Wang, E.H.M.

1993-01-01

Classical Pott's disease is described as a two-vertebrae disease with the destruction of the intervening invertebral disc. Computerized tomography has been used in the differential diagnosis of spine infections and neoplasms. We reviewed CT scans of patients seen at the Philippine General Hospital over a two-year period with atypical presentations of atypical tuberculous spondylitis. We used the computerized tomography findings described as characteristic of classical Pott's disease as criteria in evaluating the CT scans of patients diagnosed to have Atypical Pott's Disease. Although the number of patients prevented sensitivity and specificity studies to be done, our results strongly suggest that the same CT criteria used to diagnose Classical Pott's Disease may also be used to diagnose Pott's disease in its atypical form.

M. Klinger

2009-01-01

Full Text Available Background. Female patients presenting amastia associated with ectodermal dysplasia are not frequently encountered, but they are of great clinical interest and surgically demanding. Traditionally, skin alterations related to Ectodermal Dysplasia have addressed plastic surgeons to perform a two-stage approach in amastia associated with this congenital pathologic condition. This article describes an alternative method for correcting this deformity trough a mammary reconstruction in one surgical stage. Materials and Methods. We report a case of 26-year-old female patient with bilateral amastia associated with ectodermal dysplasia. Amastia in this patient was treated with implantation of subpectoral silicone gel prostheses, without previously breast tissue expansion. Results. At 18 months of follow-up after surgey, there were no complications and excellent cosmetic results were achieved. Patient and surgeon satisfaction was high and the patient underwent a bilateral areola-tattoo. Conclusions. One-stage mammary reconstruction have showed to be a reliable and effective technique also when amastia is associated with Ectodermal Dysplasia, suggesting a still satisfying biomechanical performance of the skin in this pathology.

Numerous studies have examined determinants leading to preponderance of women in major depressive disorder (MDD), which is particularly accentuated for the atypical depression subtype. It is thus of interest to explore the specific indirect effects influencing the association between sex and established depression subtypes. The data of 1624 subjects with a lifetime diagnosis of MDD derived from the population-based PsyCoLaus data were used. An atypical (n=256), a melancholic (n=422), a combined atypical and melancholic features subtype (n=198), and an unspecified MDD group (n=748) were constructed according to the DSM-IV specifiers. Path models with direct and indirect effects were applied to the data. Partial mediation of the female-related atypical and combined atypical-melancholic depression subtypes was found. Early anxiety disorders and high emotion-orientated coping acted as mediating variables between sex and the atypical depression subtype. In contrast, high Body Mass Index (BMI) served as a suppression variable, also concerning the association between sex and the combined atypical-melancholic subtype. The latter association was additionally mediated by an early age of MDD onset and early/late anxiety disorders. The use of cross-sectional data does not allow causal conclusions. This is the first study that provides evidence for a differentiation of the general mechanisms explaining sex differences of overall MDD by depression subtypes. Determinants affecting the pathways begin early in life. Since some of them are primarily of behavioral nature, the present findings could be a valuable target in mental health care.

We describe a recently noted association of congenital (infantile) pseudarthrosis of the lower leg with osteofibrous dysplasia. The patient was a 2-year-old boy who presented with a deformed left ankle joint and three cutaneous cafe-au-lait spots. Radiography demonstrated pseudarthrosis of the left distal fibula and a round lucent lesion adjacent to the proximal part of the pseudarthrosis. Histologically, the surgically removed fibula with pseudarthrosis showed a fibromatosis-like fibrovascular proliferation and nonspecific reparative changes. The focal lucent area demonstrated a fibro-osseous lesion, which was histologically identical to osteofibrous dysplasia. This case provides further evidence that osteofibrous dysplasia may be associated with congenital (infantile) pseudarthrosis of the lower leg. (orig.)

Full Text Available Hereditary Ectodermal Dysplasia is an inherited disorder commonly involving skin, teeth, hair, and nails. We have observed ectodermal dysplasia (EDs in 11 individuals over two generations in one family. Smooth, dry, thin skin was seen in most affected individuals. All had fine, slow-growing scalp hair and body hair and some had sparse eyebrows and short eyelashes. Nearly all showed decrease in sweating. Severe teeth abnormalities were seen in all patients and fingernail abnormalities were not so severe but toenail abnormalities were seen in all patients. No other abnormalities were seen in affected individuals in this family. It is very rare to find such a large family having ectodermal dysplasia.

2018-05-01

Ongoing advancements in neonatal care since the late 1980s have led to increased numbers of premature infants surviving well beyond the neonatal period. As a result of increased survival, many individuals born preterm manifest chronic respiratory symptoms throughout infancy, childhood, and adult life. The archetypical respiratory disease of prematurity, bronchopulmonary dysplasia, is the second most common chronic pediatric respiratory disease after asthma. However, there are several commonly held misconceptions. These misconceptions include that bronchopulmonary dysplasia is rare, that bronchopulmonary dysplasia resolves within the first few years of life, and that bronchopulmonary dysplasia does not impact respiratory health in adult life. This focused review describes a spectrum of respiratory conditions that individuals born prematurely may experience throughout their lifespan. Specifically, this review provides quantitative estimates of the number of individuals with alveolar, airway, and vascular phenotypes associated with bronchopulmonary dysplasia, as well as non-bronchopulmonary dysplasia respiratory phenotypes such as airway malacia, obstructive sleep apnea, and control of breathing issues. Furthermore, this review illustrates what is known about the potential for progression and/or lack of resolution of these respiratory phenotypes in childhood and adult life. Recognizing the spectrum of respiratory phenotypes associated with individuals born preterm and providing comprehensive and personalized care to these individuals may help to modulate adverse respiratory outcomes in later life.

Endoscopic Therapeutic Approach for Dysplasia in Inflammatory Bowel Disease

Directory of Open Access Journals (Sweden)

Sung Noh Hong

2017-09-01

Full Text Available Long-standing intestinal inflammation in patients with inflammatory bowel disease (IBD induces dysplastic change in the intestinal mucosa and increases the risk of subsequent colorectal cancer. The evolving endoscopic techniques and technologies, including dye spraying methods and high-definition images, have been replacing random biopsies and have been revealed as more practical and efficient for detection of dysplasia in IBD patients. In addition, they have potential usefulness in detailed characterization of lesions and in the assessment of endoscopic resectability. Most dysplastic lesions without an unclear margin, definite ulceration, non-lifting sign, and high index of malignant change with suspicion for lymph node or distant metastases can be removed endoscopically. However, endoscopic resection of dysplasia in chronic IBD patients is usually difficult because it is often complicated by submucosal fibrosis. In patients with dysplasias that demonstrate submucosa fibrosis or a large size (≥20 mm, endoscopic submucosal dissection (ESD or ESD with snaring (simplified or hybrid ESD is an alternative option and may avoid a colectomy. However, a standardized endoscopic therapeutic approach for dysplasia in IBD has not been established yet, and dedicated specialized endoscopists with interest in IBD are needed to fully investigate recent emerging techniques and technologies.

Madsen, J.S.; Reimann, I.; Svalastoga, E.

1991-01-01

In humans, delayed ossification of the caput femoris is often seen associated with hip dysplasia in babies. This phenomenon may possibly exist in dogs. In this study, the radiographic appearance of the caput femoris of 13 German shepherd dogs was examined. The dogs underwent pelvic radiography at the age of 14 to 15 days, six weeks, and 12 months. A significant relationship was shown between hip dysplasia and the late appearance of the epiphysis of the caput femoris (P=0–02). At the age of 14 to 15 days it was not possible to see both epiphyses in 54 per cent of the dogs. All of these dogs had hip dysplasia when they were 12 months old. This was in contrast to the six dogs which had both epiphyses visible when they were 14 to 15 days old. At 12 months of age, four of these dogs (67 per cent) did not show any sign of hip dysplasia

Remember the periroot sheet in orthodontic treatment of ectodermal dysplasia patients

Directory of Open Access Journals (Sweden)

Izabella Vest Hansen

2014-01-01

Full Text Available Introduction: Root resorption has various etiologies. Recent studies have demonstrated a periroot sheet covering the root. The outermost layer of this sheet is the Malassez′ epithelial layer. Tooth malformations are seen in ectodermal dysplasia and it is believed that the ectodermal layer in the periroot sheet differs in cases of ectodermal dysplasia. Case reports: Three cases of unexpected severe root resorption are demonstrated. Two cases were diagnosed with ectodermal dysplasia and the third appeared with thin, curly hair and absence of eyebrows but no ectodermal diagnosis. In the ectodermal cases, there were severe orthodontically provoked resorptions on the teeth that appeared to be permanent but were possibly primary. In the third case, there was heavy resorption on permanent teeth due to orthodontic treatment. Discussion: The orthodontist should be aware that aggressive resorption can occur in cases not diagnosed with ectodermal dysplasia but with signs of ectodermal deviations, and that tooth morphology, hair, and skin are important to observe before proceeding with treatment.

Trochlear dysplasia appears in different geometrical variations. The Dejour classification is widely used to grade the severity of trochlear dysplasia and to decide on treatment. To investigate the effect of trochlear dysplasia on patellofemoral biomechanics and to determine if different types of trochlear dysplasia have different effects on patellofemoral biomechanics. Controlled laboratory study. Trochlear dysplasia was simulated in 4 cadaveric knees by replacing the native cadaveric trochlea with different types of custom-made trochlear implants, manufactured with 3-dimensional printing. For each knee, 5 trochlear implants were designed: 1 implant simulated the native trochlea (control condition), and 4 implants simulated 4 types of trochlear dysplasia. The knees were subjected to 3 biomechanical tests: a squat simulation, an open chain extension simulation, and a patellar stability test. The patellofemoral kinematics, contact area, contact pressure, and stability were compared between the control condition (replica implants) and the trochlear dysplastic condition and among the subgroups of trochlear dysplasia. The patellofemoral joint in the trochlear dysplastic group showed increased internal rotation, lateral tilt, and lateral translation; increased contact pressures; decreased contact areas; and decreased stability when compared with the control group. Within the trochlear dysplastic group, the implants graded as Dejour type D showed the largest deviations for the kinematical parameters, and the implants graded as Dejour types B and D showed the largest deviations for the patellofemoral contact areas and pressures. Patellofemoral kinematics, contact area, contact pressure, and stability are significantly affected by trochlear dysplasia. Of all types of trochlear dysplasia, the models characterized with a pronounced trochlear bump showed the largest deviations in patellofemoral biomechanics. Investigating the relationship between the shape of the trochlea and

Odonto-onycho-dermal dysplasia is a rare autosomal recessive syndrome in which the presenting phenotype is dry hair, severe hypodontia, smooth tongue with marked reduction of fungiform and filiform papillae, onychodysplasia, keratoderma and hyperhidrosis of palms and soles, and hyperkeratosis of the skin. We studied three consanguineous Lebanese Muslim Shiite families that included six individuals affected with odonto-onycho-dermal dysplasia. Using a homozygosity-mapping strategy, we assigned the disease locus to an ~9-cM region at chromosome 2q35-q36.2, located between markers rs16853834 and D2S353, with a maximum multipoint LOD score of 5.7. Screening of candidate genes in this region led us to identify the same c.697G-->T (p.Glu233X) homozygous nonsense mutation in exon 3 of the WNT10A gene in all patients. At the protein level, the mutation is predicted to result in a premature truncated protein of 232 aa instead of 417 aa. This is the first report to our knowledge of a human phenotype resulting from a mutation in WNT10A, and it is the first demonstration of an ectodermal dysplasia caused by an altered WNT signaling pathway, expanding the list of WNT-related diseases.

Extrarenal fibromuscular dysplasia causing gastrointestinal bleeding without other manifestations and especially sparing renal vasculature is uncommon. The diagnosis of this entity is usually made by radiographic appearance and the treatment is controversial. To our knowledge only seven cases of visceral fibromuscular dysplasia as a primary manifestation of the disease have been described, symptoms range from abdominal pain to gangrene. This is the first case of visceral fibromuscular dysplasia presenting with otherwise asymptomatic gastrointestinal bleeding, without bowel necrosis or ischemic changes. We provide a review of the literature.

Craniofacial features of cleidocranial dysplasia

Chin-Yun Pan

2017-12-01

Full Text Available Cleidocranial dysplasia (CCD is an autosomal-dominant malformation syndrome affecting bones and teeth. The most common skeletal and dental abnormalities in affected individuals are hypoplastic/aplastic clavicles, open fontanelles, short stature, retention of primary teeth, delayed eruption of permanent teeth, supernumerary teeth, and multiple impacted teeth. Treatment of CCD requires a multidisciplinary approach that may include dental corrections, orthognathic surgery and cranioplasty along with management of any complications of CCD. Early diagnosis of this condition enables application of the treatment strategy that provides the best quality of life to such patients. Notably, Runx2 gene mutations have been identified in CCD patients. Therefore, further elucidation of the molecular mechanism of supernumerary teeth formation related to Runx2 mutations may improve understanding of dental development in CCD. The insights into CCD pathogenesis may assist in the development of new treatments for CCD. Keywords: cleidocranial dysplasia, mutation, Runx2, supernumerary teeth

Full Text Available Optic nerve hypoplasia can be associated with other central nervous system malformations. When associated with the absence of the septum pellucidum or thinning of corpus callosum and pituitary hypoplasia, it is termed septo-optic dysplasia. Pachygyria is a rare congenital disorder characterized by a defect in migration of cerebral neurons resulting in failure of cortical gyri to develop.We report a case of a young learning-disabled male presenting with decreased vision, nystagmus, esotropia,, and seizures since childhood. Fundoscopy revealed bilateral optic nerve hypoplasia. Growth hormone levels were reduced. Magnetic resonance imaging revealed thinned optic nerves, optic chiasma and pituitary infundibulum, absent septum pellucidum, box-shaped ventricles and right frontal cortical thickening with few and broad gyri.This case report highlights a rare case of septo-optic dysplasia with pachygyria. It also emphasizes that every patient with optic nerve hypoplasia should have an endocrinal and neurological evaluation and neuro-radiographic imaging for associated abnormalities.

Boomerang dysplasia (BD) is a perinatal lethal osteochondrodysplasia, characterised by absence or underossification of the limb bones and vertebrae. The BD phenotype is similar to a group of disorders including atelosteogenesis I, atelosteogenesis III, and dominantly inherited Larsen syndrome that we have recently shown to be associated with mutations in FLNB, the gene encoding the actin binding cytoskeletal protein, filamin B. We report the identification of mutations in FLNB in two unrelated individuals with boomerang dysplasia. The resultant substitutions, L171R and S235P, lie within the calponin homology 2 region of the actin binding domain of filamin B and occur at sites that are evolutionarily well conserved. These findings expand the phenotypic spectrum resulting from mutations in FLNB and underline the central role this protein plays during skeletogenesis in humans.

Full Text Available Ectodermal dysplasia is a rare congenital disease that affects several ectodermal structures. This disease is usually transmitted as an x-linked recessive trait in which the gene is carried by female and manifested in male. The orofacial characteristics of ectodermal dysplasia include anodontia or hypodontia, congenital teeth, underdevelopment of alveolar ridges and it is not uncommon for the face of an affected child to take on the appearance characteristic of old age, a prominent forehead, protuberant lips, a depressed nasal bridge, hypotricosis, and hypohidrosis. The treatment to manage orogacial disfigurement may afford the patient some measure of confidence, esthetics, function and speech. This case report describes the diagnosis and treatment of ectodermal dysplasia in an 18 year patient. The treatment included removable complete denture.

Ectodermal dysplasia syndrome is a hereditary disease of ectodermal origin. Appearances of nail dystrophy, alopecia or hypotrichosis, saddle nose deformity, and palmoplantar hyperkeratosis are usually associated with a lack of sweat glands as well as partial or complete absence of teeth. These manifestations are usually corrected only with oral rehabilitation by mounting dentures. In this study, plastic rehabilitation was developed to correct the special features of patients with ectodermal dysplasia. Four men and 1 woman with ectodermal dysplasia syndrome were treated. Four patients showed dysostosis of the midface, and rhinoplasty with costal bone was performed, whereas cosmetic operation aiming to repair soft tissue defects was adopted for the last patient. After plastic corrections, all 5 patients were satisfied with the results and had no social embarrassment.

The demands of hip strength and motion in ballet are high. Hip disorders, such as cam and pincer deformities or dysplasia, may affect dance performance. However, the prevalence of these radiographic findings is unknown. To determine the prevalence of radiographic cam and pincer deformities, borderline dysplasia, and dysplasia in a professional ballet company. Cross-sectional study; Level of evidence, 3. An institutional review board-approved cross-sectional investigation of a professional ballet company was undertaken. Male and female adult dancers were eligible for inclusion. Four plain radiographs were obtained (standing anteroposterior pelvis, bilateral false profile, and supine Dunn 45°) and verified for adequacy. Cam and pincer deformities, dysplasia, borderline dysplasia, and osteoarthritis were defined. All plain radiographic parameters were measured and analyzed on available radiographs. Student t test, chi-square test (and Fisher exact test), and Spearman correlation analyses were performed to compare sexes, groups, and the effect of select radiographic criteria. A total of 47 dancers were analyzed (21 males, 26 females; mean age (±SD), 23.8 ± 5.4 years). Cam deformity was identified in 25.5% (24/94) of hips and 31.9% (15/47) of subjects, with a significantly greater prevalence in male dancers than females (48% hips and 57% subjects vs 8% hips and 12% subjects; P ballet company, a high prevalence of radiographic abnormalities was found, including cam and pincer deformity and dysplasia. The results also revealed several sex-related differences of these abnormalities in this unique population. The long-term implications of these findings in this group of elite athletes remain unknown, and this issue warrants future investigation. © 2015 The Author(s).

The aim of this study was to investigate fascin and podoplanin expression in oral dysplasia and carcinoma in situ (CIS) immunohistochemically, and to evaluate their relationship to histopathological diagnosis based on architectural and cytological features. Fascin and podoplanin expression patterns were analyzed immunohistologically in 26 specimens of oral lesions, including benign disease (hyperplasia, papilloma, and others), intraepithelial neoplasia/borderline disease (dysplasia), and malignant disease (CIS, invasive squamous cell carcinoma). Fascin expression was scored into four original categories, and podoplanin expression was scored into five previously established categories. The relationship between the immunohistochemically determined scores of fascin and podoplanin expression and the architectural and cytological features in the hematoxylin-eosin-stained slides was analyzed statistically. The immunostaining scores for fascin and podoplanin were significantly higher in dysplasia and CIS than in benign disease (p=0.0011, p=0.00036), and they were significantly higher in dysplasia than in benign disease (p=0.0087, p=0.0032). In all cases of invasive SCC, fascin was expressed mainly in the cytoplasm of the tumor cells and fascin expression extended from the destruction of the basal layer of the epithelium to the upper layer of the epithelium and podoplanin was expressed in the cytoplasm and membrane of the tumor cells. This was the first report of up-regulation of fascin in oral dysplasia. Our results suggest that it would be helpful for improving the diagnostic accuracy of oral dysplasia and CIS to assess the expression of fascin and podoplanin immunohistochemically

Definitive diagnosis of pediatric ulcerative colitis (UC) may be particularly challenging since isolated colitis with overlapping features is common in pediatric Crohn's disease (CD), while atypical phenotypes of UC are not uncommon. The Paris classification allows more accurate phenotyping...... of atypical inflammatory bowel disease (IBD) patients. Our aim was to identify the prevalence of atypical disease patterns in new-onset pediatric UC using the Paris classification....

Recurring fibrous dysplasia of anthro maxillary with cranial base invasion

Directory of Open Access Journals (Sweden)

Sousa, Kátia Maria Marabuco de

2009-09-01

Full Text Available Introduction: Fibrous dysplasia is an osseous lesion with an unknown etiology. It is characterized by the osseous maturation insufficiency. It may affect any bone, but the affection of craniofacial bones is the most critical for otorhinolaryngology. Maxilla is the most affected facial bone and the orbitary invasion is an uncommon event. The symptoms are unspecific and for its low suspicion and uncommonness, the diagnosis is generally late. The monostotic form presents a slow growth and asymptomatic course and needs to be followed up. The polyostotic type has a progressive behavior and is associated to recurrence and complications. Objective: To present two cases of patients with fibrous dysplasia diagnosis and describe the clinical presentation, radiological findings and the treatment of this pathology. Cases Report: Two cases of fibrous dysplasia are reported, which initially presented unspecific symptomatology, but with characteristic radiologic signs. They were submitted to surgical treatment for resection of the lesions and evolved with frequent recurrences with extensive affection of the facial sinuses, one patient had cranial base invasion and frontal craniotomy was needed for tumoral excision. Final Comments: Fibrous dysplasia is an uncommon osteopathy. The tomography is the choice method for characterization of the tumoral expansion, and helps in the surgical planning. The surgical strategy is indicated for symptomatic lesions, functions alterations or anatomic disorders. This article describes two uncommon manifestations of recurrent fibrous dysplasia with an extensive affection of anthro maxillary, ethmoidal and sphenoid sinuses, in addition to orbitary and cranial base invasion.

Human orthopoxvirus (OPV) infections in Europe are usually caused by cowpox virus (CPXV). The genetic heterogeneity of CPXVs may in part be due to recombination with other OPV species. We describe the characterization of an atypical CPXV (CPXV-No-H2) isolated from a human patient in Norway. CPXV-No-H2 was characterized on the basis of A-type inclusion (ATI) phenotype as well as the DNA region containing the p4c and atip open reading frames. CPXV-No-H2 produced atypical V(+/) ATI, in which virions are on the surface of ATI but not within the ATI matrix. Phylogenetic analysis showed that the atip gene of CPXV-No-H2 clustered closely with that of ectromelia virus (ECTV) with a bootstrap support of 100% whereas its p4c gene is diverged compared to homologues in other OPV species. By recombination analysis we identified a putative crossover event at nucleotide 147, downstream the start of the atip gene. Our results suggest that CPXV-No-H2 originated from a recombination between CPXV and ECTV. Our findings are relevant to the evolution of OPVs. Copyright © 2011 Elsevier B.V. All rights reserved.

Background X-linked hypohidrotic ectodermal dysplasia (XLHED), the most common form of ectodermal dysplasia, is caused by mutations in the gene EDA. While only affected men develop the full-blown clinical picture, females who are heterozygous for an EDA mutation often also show symptoms such as hypodontia, hypotrichosis and hypohidrosis. These women may also suffer from malformations of the mammary gland which represent not just a cosmetic problem but can limit their breastfeeding capability. This paper summarizes the findings of the first systematic study on the impact of hypohidrotic ectodermal dysplasia on breastfeeding. Patients Thirty-eight adult female members of the German-Swiss-Austrian ectodermal dysplasia patient support group participated in a structured interview; most of them also agreed to a photodocumentation of their mammary region. Thirty-one women carried mutations in EDA (Group A) and seven were affected by other forms of hypohidrotic ectodermal dysplasia (Group B). Results 39 % of the women of Group A reported that their breasts were of different size or entirely absent on one side. In Group B, 86 % of the women reported differently sized or even absent breasts; two of these women lacked both breasts entirely. Most women described their nipples as exceptionally flat. 10 % of the women of Group A had more than two nipples. The high percentage of deviations from the norm was confirmed in the photodocumentation. Both groups had few or no sebaceous glands of Montgomery in the areolar region. Around 80 % of interviewed women had children and had attempted to breastfeed their first child. 67 % of the mothers in Group A had had difficulty in breastfeeding their infants and generally attributed this difficulty to their flat nipples. All of the mothers in Group B reported difficulties in breastfeeding; 60 % had not been able to breastfeed their first child. Conclusion Mothers with hypohidrotic ectodermal dysplasia very often have difficulty

Atypical Cutaneous Manifestations in Syphilis.

Although the diversity of the clinical manifestations of syphilis is well-known, atypical presentations can also occur. Such atypical presentations are associated with a high risk of transmission as a result of diagnostic confusion and treatment delays owing to the disease's ability to mimic other common skin diseases, deviate from classic clinical presentations, and adopt unique forms. Cases of atypical syphilis have been described most frequently in patients with concomitant human immunodeficiency virus (HIV) infection. Because the incidence of syphilis has been growing over recent years -particularly in patients with HIV co-infection- dermatologists need to be familiar with the less well-known clinical presentations of this venereal disease.

The aim of this study was the characterization of a new subtype of high-grade cervical squamous intraepithelial lesion (HSIL) with enlarged cells containing bizarre nuclei: so-called bizarre cell dysplasia (BCD). A total of 29 cervical cone biopsy samples of this type of dysplasia were studied. Multi-target polymerase chain reaction and in situ hybridization human papillomavirus (HPV) detection was performed in all cases. BCD was defined as a subtype of HSIL characterized by the presence of large dysplastic cells with abnormal, large pleomorphic nuclei or multinucleation causing nucleomegaly. This results in bizarre nuclear shapes. Bizarre cells are scattered throughout the whole thickness of the dysplastic squamous epithelium. The BCD lesions arise within the conventional/classic high grade or "bland" type squamous dysplasia HSIL. Statistically they were significantly associated with HVP type 16. A significant association with other studied viruses (Herpes simplex virus [HSV]1, HSV2, Varicella zoster virus, Epstein-Barr virus, cytomegalovirus, human herpesvirus 6, and human polyomaviruses BK and JC) was not confirmed. BCD involves cytologically characteristic morphologic changes that are recognizable, but which may pose some risk of misdiagnosis as low-grade squamous intraepithelial lesion due to the enlargement of dysplastic cells and multinucleation. Based on the unique histological, cytological and biological features of BCD including strong association with HPV 16 infection, we believe that this is a specific, and so far unrecognized variant of HSIL. © 2017 Japan Society of Obstetrics and Gynecology.

A skeletal dysplasia with previously unreported features is presented. Its evolution was characterized by growth abnormalities of bones without involvement of other organs. Advanced bone age, increased stature and irregular epiphyseal ossification with stippling of the main long bones were documented. Physeal overgrowth was massive in the left proximal humerus and femur. Furthermore, the hip joint appeared fused with an abundant mass of pathological calcific tissue extending from the femur to the ilium. Pathological epiphyses were characterized by anarchic cartilaginous proliferation with multiple ossification centres, while lamellar bone apposition and remodelling were normal. The observed bone changes were different from those in any previously reported syndrome, metabolic defect or bone dysplasia. However, they clearly indicated a defect of endochondral ossification with some resemblance to phenotypes observed in dysplasia epiphysealis hemimelica. (orig.)

2014-01-01

Full Text Available We describe a case of anhidrotic ectodermal dysplasia (AED with an autosomal recessive mode of inheritance, a very rare entity, in a 2-year-old female child of two asymptomatic, consanguineous parents. Their previous child also had a similar condition. Autosomal recessive AED (AR-AED can have its full expression both in males and females and it is clinically indistinguishable from the x-linked recessive AED (XL-AED, which is the most common type of ectodermal dysplasia. Unlike the partially symptomatic carriers of XL-AED, the heterozygotes of AR-AED are phenotypically asymptomatic.

Hip dysplasia is a common developmental disorder of the dog, consisting of varying degrees of hip laxity, progressive remodeling of the structures of the hip, and subsequent development of osteoarthritis. It is a juvenile-onset condition, with clinical signs often first evident at 4 to 12 months of age. A tentative diagnosis of hip dysplasia can be made based on signalment, history, and physical examination findings. The Ortolani test is a valuable tool for identifying juvenile dogs affected with this condition. Further diagnostics can then be prioritized, contributing to prompt diagnosis and appropriate treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

The Diagnostic importance of clinical and radiologic features of the Multiple Cemento-osseous dysplasia

Han, M. R.; Kim, Y. H.; Kang, B. C.

1998-01-01

This case was diagnosed as multiple cementoosseous dysplasia on the basis of clinical and radiological features but was diagnosed as ossifying fibroma on the basis of histopathological feature. The histopathologic features of the multiple cementoosseous dysplasia and cementoossifying fibroma have common features of cementum, fibrous network and bone. Multiple cementoosseous dysplasia is reactive lesion and shows restricted lesion size, occurred on anterior and posterior tooth of the mandible and needs no treatment except periodic follow up. But Cementoossifying fibroma is the true neoplasm and grows continuously and needs surgical removal. The final diagnosis of the multiple cementoosseous dysplasia requires good correlation of the clinical histopathological, and radiological features.

Full Text Available Ectodermal dysplasia is a hereditary disorder associated with abnormal development of embryonic ectodermally-derived organs including teeth, nails, hair and sweat glands. Hypodontia of the primary and permanent dentition is the most common oral finding. Therefore, affected patients need dental prosthetic treatments during their developmental years. This report presents two cases of children affected by ectodermal dysplasia with anodontia. Oral rehabilitation was accomplished with removable acrylic prostheses. Treatment had major impacts on self-esteem, masticatory function, speech and facial esthetic.

2014-01-01

Full Text Available Background. Capabilities of assessing functional condition of the respiratory system in young children, including patients with bronchopulmonary dysplasia, are extremely limited, as little children do not cooperate with doctors in the course of diagnostic procedures. Results of use of a modern instrumental diagnostic method in this group of patients is of doubtless interest. The study was aimed at tracking changes in functional condition of the respiratory system in children with bronchopulmonary dysplasia during follow-up. Methods. Quite breathing flowmetry during natural sleep. Results. The article presents the authors’ data obtained by means of analyzing external respiratory function in children with bronchopulmonary dysplasia using a modern method of quiet breathing flowmetry; it is also reasonable to use relative parameters of the external respiratory function as diagnostic criteria of bronchoobstructive syndrome at bronchopulmonary dysplasia and criteria of effectiveness of N-acetylcysteine mucolytic therapy. Conclusion. Quiet breathing flowmetry may be used to diagnose bronchoobstructive syndrome and assess effectiveness of the treatment thereof in children with bronchopulmonary dysplasia.

Full Text Available Ectodermal dysplasia is characterized by the absence or defects of two or more ectodermally derived structures. Anodontia or hypodontia is the most striking dental manifestation. In severe hypodontia, there is lack of alveolar development with consequent protrusion and eversion of the lips. Patients with anhidrotic forms suffer from heat intolerance due to lack of sweat glands and mild infections may lead to death in infancy from hyperthermia. A case of a 4-year-old child with anhidrotic ectodermal dysplasia with partial anodontia is presented. Dental, oral, and physical features were taken into consideration in diagnosis and treatment planning for this patient. Clinical management consisted of removable partial prosthesis in maxillary arch and complete denture prosthesis in mandibular arch. The main aim of the treatment was to improve psychological development and to promote better functioning of the stomatognathic system.

Elbow dysplasia in the dog : pathophysiology, diagnosis and control : review article

Directory of Open Access Journals (Sweden)

R.M. Kirberger

1998-07-01

Full Text Available Elbow dysplasia is a non-specific term denoting abnormal development of the elbow. Elbow dysplasia encompasses the clinical and radiographic manifestation of ununited anconeal process, fragmented medial coronoid process, osteochondritis dissecans, erosive cartilage lesions and elbow incongruity. The net result is elbow arthrosis, which may be clinically inapparent or result in marked lameness. These conditions may be diagnosed by means of routine or special radiographic views and other imaging modalities, or the precise cause of the arthrosis or lameness may remain undetermined. Breeds most commonly affected are the rottweiler, Bernese mountain dog, Labrador and golden retriever and the German shepherd dog. Certain breeds are more susceptible to a particular form of elbow dysplasia and more than 1 component may occur simultaneously. The various conditions are thought to result from osteochondrosis of the articular or physeal cartilage that results in disparate growth of the radius and ulna. Heritability has been proven for this polygenic condition and screening programmes to select suitable breeding stock have been initiated in several countries and have decreased the incidence of elbow dysplasia.

Cardio-facio-cutaneous syndrome (CFC), Noonan syndrome (NS), and Costello syndrome are a group of diseases that belong to the RASopathies. The syndromes share clinical features making diagnosis a challenge. To investigate the phenotype and genotype of a 10-year-old Iraqi girl with overlapping features of CFC, NS, and Costello syndromes, with additional features of ectodermal dysplasia. DNA was examined by exome sequencing and protein expression by immunohistochemistry. Exome sequencing identified a mutation in the SOS1 gene and a de novo deletion in the FOXI2 gene which was neither present in the international databases, nor in 400 chromosomes from the same population. Based on immunohistochemical staining, FOXI2 was identified in the basal cell layer of the skin and overlapped with the expression of P63, a major player in ectodermal dysplasia. We therefore suggest screening for FOXI2 mutation in the setting of ectodermal features that are not associated with genes known to contribute to ectodermal dysplasia.

Full Text Available Introduction: Ectodermal dysplasia (ED is a hereditary disorder associated with developmental disorders of two or more structures of ectodermal embryonic origin. Hypodontia or anodontia of the primary and permanent dentition, poorly developed alveolar ridges and improper maxillo – mandibular relations, are the most common oral manifestations. Management of patients with ectodermal dysplasia requires a multidisciplinary team approach. Case presentation: A 6.5 year-old boy with hypohidrotic ectodermal dysplasia (HED presented in this article, had typical features of HED: hypohidrosis, hypotrichosis, severe hypodontia, atrophic alveolar ridges, old-looking facial expression. According to the patient’s age and clinical findings, removable complete over-denture prosthesis in both arches was the treatment of choice. Conclusion: In patients with ED, it is important to establish correct maxillo – mandibular relations and normal function of the dento-facial system (chewing, swallowing, and speaking. Prosthodontic treatment has a major impact on aesthetics and functions,facilitates psychological development and improves emotional condition and social life of the patient.

2015-01-01

Osseous dysplasias are the most common subtype of fibro-osseous lesions of the maxillofacial bones. They are benign and often present as incidental asymptomatic lesions. Diagnosis can be made with clinical and radiographic examination. This article reports the case of a 47-year-old man with a huge cementifying osseous dysplasia of the maxilla that presented with secondary infection after teeth extraction and repair of oroantral fistula. A subtotal maxillectomy had to be done after conservative treatment failed to resolve the infection. Biopsy, tooth extraction or surgical trauma to the affected bones of osseous dysplasia could easily lead to severe secondary infection, the treatment of which may be very difficult, and thus should be avoided if possible.

Ectodermal dysplasias form a complex, nosologic group of diseases with defects in at least 2 ectodermal structures. A retrospective study of patients with ectodermal dysplasia seen at our department over a period of 19 years (1994-2013) was performed. The study population consisted of 67 patients covering 17 different diagnoses. Forty-five families were identified of which 26 were sporadic cases with no affected family members. In 27 tested families a disease-causing mutation was identified in 23 families. Eleven mutations were novel mutations. To our knowledge, we present the first large ectodermal dysplasia cohort focusing on clinical manifestations in combination with mutational analysis. We recommend a nationwide study to estimate the prevalence of the ectodermal dysplasia and to ensure relevant molecular genetic testing which may form the basis of a national ectodermal dysplasia database.

Forty-three patients with maxillo-nasal dysplasia have been subjected to a radiographic examination of the cervical spine. In 44.2 per cent malformations of the cervical vertebrae of a minor or major type were revealed. Dysplasia of the vertebral bodies related to persistence of the chorda dorsalis, a very rare malformation, was found in six cases. No correlation between the incidence or serverity of the malformations and the degree of malocclusion of the jaws and facial deformity, characteristic of Binder syndrome, were noted. The maxillo-nasal dysplasia and the spinal malformations probably have a common cause during the embryologic stage. (orig.)

Oculodentodigital dysplasia is caused by mutations in the GJA1 gene. Oculodentodigital dysplasia presents with a spectrum of clinical features including craniofacial, ocular, dental, and limb anomalies. Although recent findings implicate the major role of GJA1 during cardiac organogenesis, congenital heart defects are infrequently reported in oculodentodigital dysplasia. Here we report on two patients with GJA1 mutations presenting with cardiac malformations and type III syndactyly. Patient 1 presented with pulmonary atresia, an intact septum, right ventricular hypoplasia and tricuspid stenosis. The infant had a small nose, thin columella and bilateral 4-5 syndactyly of the fingers. A de novo c.226C>T (p.Arg76Cys) mutation was identified. Patient 2 presented at 6 months with a ventricular septal defect. The child had hypoplastic alae nasi with a thin columella and bilateral 4-5 syndactyly of the digits. A de novo missense mutation, c.145C>G (p.Gln49Glu) was found. Our two patients underscore the importance of cardiac evaluations as part of the initial workup for patients with findings of oculodentodigital dysplasia. Conversely, those patients with type III syndactyly and congenital heart defect should be screened for GJA1 mutations. © 2013 Wiley Periodicals, Inc.

Full Text Available Introduction: Cement osseous dysplasia is the most common lesion of the family fibrous dysplasia which normal bone is replaced with fibrous tissue and several mineralized material. These lesions may be seen in association with various lesions. Companionship of this lesion with odontoma has been reported rarely. Case report: A 44-year-old female in one year ago has admitted to Shahid Sadoughi Faculty of Dentistry Yazd for treatment of mandibular left third molar. In panoramic radiography in the mandibular left first molar region, a mixed lesion of radiolucent-radiopaque with a corticated borderwas seen. Small swelling was observed in this area. Microscopically, the diagnosis of osseous dysplasia with odontoma for the lesion was confirmed. Conclusion: The reason of companionship of cement osseous lesions whit other lesions is not completely clear and it requires further evaluation.

Co-occurence of florid cemento-osseous dysplasia and simple bone cyst: a case report.

2011-01-01

The purpose of this report is to present a rare case of co-occurrence of florid cemento-osseous dysplasia with simple bone cyst in a middle aged Asian woman. Most of the reported cases are isolated cases of simple bone cyst or florid cemento-osseous dysplasia, but co-occurrence of these two entities is extremely rare. The authors report a 41 year old female patient with co-occurrence of mandibular florid cemento-osseous dysplasia with simple bone cyst. A thorough clinical and radiological examination was carried out. It was diagnosed mandibular cyst with possible co-occurrence of florid cemento-osseous dysplasia. Surgical exploration of the multilocular lesion was applied. Since, the patient was symptomatic at the time of presentation utmost caution was taken during the surgical procedure as florid cemento-osseous dysplasia is associated with hypo-vascularity of the affected bone. Based on histopathological, as well as supporting clinico-radiological findings a confirmative diagnosis of florid cemento-osseous dysplasia co-occurring with simple bone cyst was made. Patient was followed-up for a period of six months and was reported to be asymptomatic. Timely diagnosis and well planned treatment is important to obtain a good prognosis when a rare co-occurrence of two or more bone lesions affects the jaws.

p53 expression and mutation analysis of odontogenic cysts with and without dysplasia.

Science.gov (United States)

Cox, Darren P

2012-01-01

Overexpression of p53 protein is well described in odontogenic cystic lesions (OCLs), including those with epithelial dysplasia; however, most p53 antibodies stain both wild-type and mutated p53 protein and may not reflect genotype. Direct sequencing of the p53 gene has not identified mutations in OCLs with dysplasia. The purpose of this study was to determine the molecular basis of p53 expression in several types of OCLs with and without dysplasia. The study material comprised 13 OCLs: odontogenic keratocyst (n = 5), orthokeratinized odontogenic cyst (n = 5), dentigerous cyst (n = 2), lateral periodontal cyst (n = 1), and unspecified developmental odontogenic cyst (UDOC) (n = 1). Five of these had features of mild or moderate epithelial dysplasia. One intraosseous squamous cell carcinoma (SCC) that was believed to have arisen from an antecedent dysplastic orthokeratinized OC was also included. Immunohistochemistry was performed using the DO7 monoclonal antibody that recognizes wild-type and mutated p53. DNA was extracted from microdissected tissue for all samples and exons 4 to 8 of the p53 gene direct sequenced. In 4 of 5 OCLs with dysplasia there was strong nuclear staining of basal and suprabasal cells. In all cases without dysplasia, nuclear expression in basal cells was either negative or weak and was absent in suprabasal cell nuclei. A mutation in exon 6 of the p53 gene (E224D) was identified in both the dysplastic orthokeratinized OC and the subsequent intraosseous SCC. OCLs with features of dysplasia show increased expression of p53 protein that does not reflect p53 mutational status. One dysplastic OC shared the same p53 mutation with a subsequent intraosseous SCC, indicating that p53 mutation may be associated with malignant transformation in this case.

We report a family in which two sibs have both achondroplasia and pseudoachondroplastic dysplasia. The mother has achondroplasia and the father has pseudoachondroplastic dysplasia, which he had inherited from his father. Both children appeared typical of achondroplasia at birth. By 1 1/2 years they had developed a fixed lumbar kyphosis with gibbus and had additional x ray changes unusual for just achondroplasia and suggestive of pseudoachondroplastic dysplasia. Subsequently both children have shown characteristic features of both conditions and have grown less well than expected for achondroplasia. Radiographs show the striking synergistic effects of the two conditions. MRI in both sibs confirmed brain stem compression at the foramen magnum. This may be an important complication and should be actively sought in any double heterozygote. Images PMID:7966194

Radiographic signs of acetabular dysplasia of the adult hip

1981-06-01

Many papers have been published about the different types of measurements used in the evaluation of hip dysplasia in the pediatric age group. However, there are no publications that deal with this topic regarding adults. The authors present an initial series of measurements of the angle of the roof of the acetabulum in 100 randomized asymptomatic adult males. The normal value ranged from -10/sup 0/ to +10/sup 0/. These measurements were correlated with those described by Wiberg. The combination of both methods yields highly reliable information in the evaluation of hip dysplasia.

Trochlear dysplasia is a well-described risk factor for recurrent patellofemoral instability. Despite its clear association with the incidence of patellofemoral instability, it is unclear whether the presence of high-grade trochlear dysplasia influences clinical outcome after patellofemoral stabilization. The purpose of this study was to assess whether trochlear dysplasia influenced patient-reported, disease-specific outcomes in surgically treated patellar instability patients, when risk factors were addressed in accordance with the à la carte surgical approach to the treatment of patellofemoral instability. The study design is of a case series. A total of 318 patellar stabilization procedures were performed during the study period. Of these procedures, 260 had adequate lateral radiographs and complete Banff Patellar Instability Instrument (BPII) scores available for assessment. A Pearson r correlation was calculated between four characteristics of trochlear dysplasia, the BPII total and the BPII symptoms, and physical complaints scores, a mean of 24 months following patellofemoral stabilization. Independent t -tests were performed between stratified trochlear dysplasia groups (no/low grade and high grade) and all BPII measures. There was a statistically significant correlation between measures of trochlear dysplasia and quality-of-life physical symptoms scores, an average of 2 years following patellofemoral stabilization surgery. The BPII symptoms and physical complaints domain score, as well as the individual weakness and stiffness questions, correlated with the classification of trochlear dysplasia as well as the presence of a trochlear bump ( p  patellofemoral stabilization surgery. There was a significant correlation between patient-reported physical symptoms after surgery and high-grade trochlear dysplasia.

This study was carried out to determine the underestimation rate of carcinoma upon surgical biopsy after a diagnosis of flat epithelial atypia and atypical ductal hyperplasia and 11-gauge vacuum-assisted breast biopsy. A retrospective review was conducted of 476 vacuum-assisted breast biopsy performed from May 2005 to January 2007 and a total of 70 cases of atypia were identified. Fifty cases (71%) were categorized as pure atypical ductal hyperplasia, 18 (26%) as pure flat epithelial atypia and two (3%) as concomitant flat epithelial atypia and atypical ductal hyperplasia. Each group were compared with the subsequent open surgical specimens. Surgical biopsy was performed in 44 patients with atypical ductal hyperplasia, 15 patients with flat epithelial atypia, and two patients with flat epithelial atypia and atypical ductal hyperplasia. Five cases of atypical ductal hyperplasia were upgraded to ductal carcinoma in situ, three cases of flat epithelial atypia yielded one ductal carcinoma in situ and two cases of invasive ductal carcinoma, and one case of flat epithelial atypia/atypical ductal hyperplasia had invasive ductal carcinoma. The overall rate of malignancy was 16% for atypical ductal hyperplasia (including flat epithelial atypia/atypical ductal hyperplasia patients) and 20% for flat epithelial atypia. The presence of flat epithelial atypia and atypical ductal hyperplasia at biopsy requires careful consideration, and surgical excision should be suggested.

We can Diagnose it if we Consider it. Diagnostic Pitfall for Placenta: Placental Mesenchymal Dysplasia

Full Text Available Placental mesenchymal dysplasia is an increasingly recognizable abnormality. Early cases have been confused with partial hydatidiform mole. Placental mesenchymal dysplasia is probably under-diagnosed because of being an unfamiliar clinical entity and also mistaken for gestational trophoblastic disease due to the similar sonographic findings of two entities. In this report, we describe the clinical, gross, and histopathological findings of placental mesenchymal dysplasia in two cases. The 33-week-preterm baby of a 26-year-old woman with cardiovascular disease and 342 gram placenta and the 19-week fetus with trisomy 21 of a 40 year-old woman were terminated. Macroscopically thick-walled vessels and microscopically hydropic villous with peripherally localized thick-walled vessels without trophoblastic cell proliferation were observed in both cases. These two cases represent a rare placental anomaly that is benign but it is challenging to distinguish placental mesenchymal dysplasia from an incomplete mole. Placental mesenchymal dysplasia should be included in the differential diagnosis of sonographic findings that show a normal appearing fetus and a placenta with cystic lesions. Placental mesenchymal dysplasia is associated with pregnancy-related hypertension. In conclusion, the most important point is “you can diagnose it if you consider it”.

Patients with pancolitis and long-standing ulcerative colitis are at increased risk of developing colorectal cancer, so it is advisable to colonoscopic surveillance. The objective of this study was to identify the endoscopic visualization system of imaging with narrowband and overexpression of the p53 protein as procedures useful for the research of Dysplasia in patients with ulcerative colitis and pancolitis, of eight or more years of evolution. A prospective, descriptive study was performed on 50 patients. The Fisher exact probability test was used for the statistical study and of square Chi, with a level of significance α = 0.05. Shown with narrow-band image increases the likelihood of finding suggestive areas of Dysplasia, reduces the amount of biopsy and gets a higher proportion of diagnoses of Dysplasia in fewer samples (70.4%). The overexpression of the p53 protein was associated with the presence of dysplasia (80.0%) p < 0.001 and is immunoexpress in samples with a high degree of severity of dysplasia and the low grade. Concluded that imaging with narrowband system and overexpression of the p53 protein are procedures useful for the research of Dysplasia in these patients. (author)

Kaposiform hemangioendothelioma (KHE) is a rare vascular tumor of early childhood and infancy. Kasabach-Merritt phenomenon, a common complication of KHE, is characterized by life-threatening thrombocytopenia, hemolytic anemia, and consumption coagulopathy. There may be atypical cases that do not present with Kasabach-Merritt phenomenon and do have atypical imaging findings. Knowledge of atypical imaging features may assist radiologists in identifying KHE. In this report, we present a 4-year-old case of KHE with atypical ultrasound findings.

Neurobiological abnormalities underlying atypical depression have previously been suggested. The purpose of this study was to explore differences at functional brain imaging between depressed patients with and without atypical features and healthy controls. Twenty-three out-patients with chronic depressive disorder recruited from a service for patients with audiological symptoms were investigated. Eleven fulfilled the DSM-IV criteria for atypical depression (mood reactivity and at least two of the following: weight gain, hypersomnia, leaden paralysis and interpersonal rejection sensitivity). Twenty-three healthy subjects served as controls. Voxel-based analysis was applied to explore differences in {sup 99m}Tc-HMPAO uptake between groups. Patients in the atypical group had a higher prevalence of bilateral hearing impairment and higher depression and somatic distress ratings at the time of SPECT. Significantly higher tracer uptake was found bilaterally in the atypical group as compared with the non-atypicals in the sensorimotor (Brodmann areas, BA1-3) and premotor cortex in the superior frontal gyri (BA6), in the middle frontal cortex (BA8), in the parietal associative cortex (BA5, BA7) and in the inferior parietal lobule (BA40). Significantly lower tracer distribution was found in the right hemisphere in the non-atypicals compared with the controls in BA6, BA8, BA44, BA45 and BA46 in the frontal cortex, in the orbito-frontal cortex (BA11, BA47), in the postcentral parietal cortex (BA2) and in the multimodal association parietal cortex (BA40). The differences found between atypical and non-atypical depressed patients suggest different neurobiological substrates in these patient groups. The putative links with the clinical features of atypical depression are discussed. These findings encourage the use of functional neuroimaging in psychiatric disorders. (orig.)

2005-04-01

Persistent reports have linked atypical antipsychotics with diabetes, yet causative mechanisms responsible for this linkage are unclear. Goals of this review are to outline the pathogenesis of nonimmune diabetes and to survey the available literature related to why antipsychotics may lead to this disease. We accessed the literature regarding atypical antipsychotics and glucose homeostasis using PubMed. The search included English-language publications from 1990 through October 2004. Keywords used included atypical antipsychotics plus one of the following: glucose, insulin, glucose tolerance, obesity, or diabetes. In addition, we culled information from published abstracts from several national and international scientific meetings for the years 2001 through 2004, including the American Diabetes Association, the International Congress on Schizophrenia Research, and the American College of Neuropsychopharmacology. The latter search was necessary because of the paucity of well-controlled prospective studies. We examined publications with significant new data or publications that contributed to the overall comprehension of the impact of atypical antipsychotics on glucose metabolism. We favored original peer-reviewed articles and were less likely to cite single case studies and/or anecdotal information. Approximately 75% of the fewer than 150 identified articles were examined and included in this review. Validity of data was evaluated using the existence of peer-review status as well as our own experience with methodology described in the specific articles. The metabolic profile caused by atypical antipsychotic treatment resembles type 2 diabetes. These agents cause weight gain in treated subjects and may induce obesity in both visceral and subcutaneous depots, as occurs in diabetes. Insulin resistance, usually associated with obesity, occurs to varying degrees with different antipsychotics, although more comparative studies with direct assessment of resistance are

Arrhythmogenic right ventricular dysplasia: A case report

Directory of Open Access Journals (Sweden)

Tessa Negrín Valdés

2015-10-01

Full Text Available Arrhythmogenic right ventricular dysplasia is a heart muscle disease that predominantly affects the right ventricle, bringing about the replacement of normal myocardium with fatty or fibrofatty tissue and causing sudden death in young individuals. Ventricular tachycardia is an important clinical manifestation, although there are reports of right or global heart failure. The diagnosis is confirmed by echocardiography and magnetic resonance imaging. The case of a 65-year-old former smoker, with hypertension and ischemic heart disease, a history of effort syncope symptoms and proven non-sustained ventricular tachycardia, with morphology of left bundle branch block, is reported. Relevant diagnostic studies were performed, and echocardiographic elements which were compatible with arrhythmogenic right ventricular dysplasia were found. Therefore, an implantable cardioverter defibrillator was implanted, after which the patient has had a favorable outcome.

ATYPICAL ANTIPSYCHOTICS USE IN CHILDREN AND ADOLESCENTS

Nataša Potočnik-Dajčman

2002-06-01

Full Text Available Background. Classical antipsychotics – neuroleptics are one of the most frequently prescribed psychotropic drugs in child psychiatry. Atypical antipsychotics are used for the same indications – psychotic (schizophrenia as well as unpsychotic disorders (pervasive developmental disorders, mood disorders, conduct disorders and tics disorders. It is surprising that the studies on their use with regard to this age group are rather rare. They are carried out on a small number of samples and only exceptionally double blind. This article summarizes published clinical experience with atypical antipsychotics in children and adolescents. A short overview of pharmacodynamics, pharmacokinetics and side effects is given. Schizophrenia and pervasive developmental disorders are major indications for use of atypical antipsychotics in children and adolescents, but they have also been successfully used for other disorders such as aggressive behaviour, tics and anorexia nervosa.Conclusions. With better side-effect profile, some of the atypical antipsychotics are expected to be doctrinally recognised as the first-line treatment for childhood schizophrenia and pervasive developmental disorders. However, more long-term studies carried out on a larger sample are needed. Atypical antipsychotics are already used in everyday practice as first-line treatment of childhood and adolescents schizophrenia.

Accurate understanding of the cause of the underlying pathology in children with diastrophic dysplasia would help in designing targeted management of their locomotion. Diastrophic dysplasia was diagnosed in twelve patients (nine girls and three boys; age range 1-14 years), all of whom presented with small stature and apparent short extremities. Club foot (mostly talipes equinovarus) was the most frequent and consistent abnormality. Concomitant abnormalities such as hip flexion contracture, flexion contractures of the knees with excessive valgus deformity and lateral patellar subluxation, were also encountered. Muscle ultrasound and muscle magnetic resonance imaging imaging showed no myopathic changes and muscle biopsies and the respiratory chain were normal. Serum choline kinase and plasma lactate concentrations were normal. Surgical correction of the foot and ankle in patients with diastrophic dysplasia is extremely difficult because of the markedly distorted anatomy. In all of these children, plantigrade foot was achieved along with the improved function of the locomotor system. Mutations of the diastrophic dysplasia sulfate transporter (also known as solute carrier family 26 member 2) were encountered. Arthrogryposis multiplex is the usual terminology used to describe the abnormality in infants with multiple contractures. Diligent orthopaedic care should be provided based on an accurate understanding of the associated syndromes in such children. © 2014 Chinese Orthopaedic Association and Wiley Publishing Asia Pty Ltd.

The chemokine system is a fundamental component of cancer-related inflammation involved in all stages of cancer development. It controls not only leukocyte infiltration in primary tumors but also angiogenesis, cancer cell proliferation, and migration to metastatic sites. Atypical chemokine receptors are a new, emerging class of regulators of the chemokine system. They control chemokine bioavailability by scavenging, transporting, or storing chemokines. They can also regulate the activity of canonical chemokine receptors with which they share the ligands by forming heterodimers or by modulating their expression levels or signaling activity. Here, we summarize recent results about the role of these receptors (atypical chemokine receptor 1/Duffy antigen receptor for chemokine, atypical chemokine receptor 2/D6, atypical chemokine receptor 3/CXC-chemokine receptor 7, and atypical chemokine receptor 4/CC-chemokine receptor-like 1) on the tumorigenesis process, indicating that their effects are strictly dependent on the cell type on which they are expressed and on their coexpression with other chemokine receptors. Indeed, atypical chemokine receptors inhibit tumor growth and progression through their activity as negative regulators of chemokine bioavailability, whereas, on the contrary, they can promote tumorigenesis when they regulate the signaling of other chemokine receptors, such as CXC-chemokine receptor 4. Thus, atypical chemokine receptors are key components of the regulatory network of inflammation and immunity in cancer and may have a major effect on anti-inflammatory and immunotherapeutic strategies. © Society for Leukocyte Biology.

Primary cellular meningeal defects cause neocortical dysplasia and dyslamination

Objective Cortical malformations are important causes of neurological morbidity, but in many cases their etiology is poorly understood. Mice with Foxc1 mutations have cellular defects in meningeal development. We use hypomorphic and null alleles of Foxc1 to study the effect of meningeal defects on neocortical organization. Methods Embryos with loss of Foxc1 activity were generated using the hypomorphic Foxc1hith allele and the null Foxc1lacZ allele. Immunohistologic analysis was used to assess cerebral basement membrane integrity, marginal zone heterotopia formation, neuronal overmigration, meningeal defects, and changes in basement membrane composition. Dysplasia severity was quantified using two measures. Results Cortical dysplasia resembling cobblestone cortex, with basement membrane breakdown and lamination defects, is seen in Foxc1 mutants. As Foxc1 activity was reduced, abnormalities in basement membrane integrity, heterotopia formation, neuronal overmigration, and meningeal development appeared earlier in gestation and were more severe. Surprisingly, the basement membrane appeared intact at early stages of development in the face of severe deficits in meningeal development. Prominent defects in basement membrane integrity appeared as development proceeded. Molecular analysis of basement membrane laminin subunits demonstrated that loss of the meninges led to changes in basement membrane composition. Interpretation Cortical dysplasia can be caused by cellular defects in the meninges. The meninges are not required for basement membrane establishment but are needed for remodeling as the brain expands. Specific changes in basement membrane composition may contribute to subsequent breakdown. Our study raises the possibility that primary meningeal defects may cortical dysplasia in some cases.

The objective of this article is to attract the attention of clinical physicians to the rare but extremely relevant clinical pathology of mesenchymal dysplasias (Marfan syndrome, Ehlers-Danlos syndrome, hereditary hemorrhagic telangiectasia) and especially specific characteristics of such diseases during pregnancy. Connective tissue pathology can cover different organs and systems, symptoms of the same disease can vary in different patients thus making diagnostics significantly difficult. Here clinical diagnostic criteria and methods of molecular diagnostics of diseases are described. The pathogenesis of mesenchymal dysplasias is not currently well understood. For the patients with mesenchymal dysplasias pregnancy is fraught with high risk of life-threatening complications. The preferred delivery method for such patients is caesarean section.

Ectodermal dysplasia is a hereditary disorder of ectodermal origin. A 12-year-old boy was referred for management of the oral manifestations of his ectodermal dysplasia. An overdenture retained by natural teeth for the maxilla and a double-crown-retained denture for the mandible were made. Double-crown-retained dentures may be modified into complete dentures if the abutment teeth are lost. The patient was instructed to maintain oral hygiene and return periodically for follow-up visits. This report describes a potential routine approach to restoring the appearance, function, and psyche of a growing boy with ectodermal dysplasia.

Fibrous dysplasia is characterized by a progressive replacement of normal bone elements by fibrous tissue. The temporal bone is rarely involved. In this location, complications such as facial deformity, conductive hearing loss and facial peripheral neural involvement can occur. Positive diagnosis can be established with computerized tomography which also enables assessment of extension and detection of complications. We report a case of a 27-year-old man with extensive fibrous dysplasia of the right temporal bone presenting with conductive hearing loss secondary to progressive stenosis of the external auditory canal. Computerized tomography of the temporal region was performed. (authors)

The skin, hair and nail changes in four distinct ectodermal dysplasia syndromes are compared and reviewed. These syndromes comprise Christ-Siemens-Touraine syndrome; ectrodactyly, ectodermal dysplasia and cleft lip/palate syndrome; ankyloblepharon-ectodermal defects-cleft lip/palate syndrome and Rapp-Hodgkin syndrome. A comprehensive overview of the dermatological signs and symptoms in these syndromes was generated from the database of the Ectodermal Dysplasia Network Germany, the clinical findings in the patients seen in our department and an extensive review of the literature. The findings included abnormalities of skin, sweating, hair and nails. These clinical findings are discussed in relation to the underlying molecular defects known to play a role in these four ectodermal dysplasia syndromes.

Atypical sexual behavior during sleep.

Guilleminault, Christian; Moscovitch, Adam; Yuen, Kin; Poyares, Dalva

2002-01-01

This article reports a case series of atypical sexual behavior during sleep, which is often harmful to patients or bed partners. Eleven subjects underwent clinical evaluation of complaints of sleep-related atypical sexual behavior. Complaints included violent masturbation, sexual assaults, and continuous (and loud) sexual vocalizations during sleep. One case was a medical-legal case. Sleep logs, clinical evaluations, sleep questionnaires, structured psychiatric interviews, polysomnography, actigraphy, home electroencephalographic monitoring during sleep, and clinical electroencephalographic monitoring while awake and asleep were used to determine clinical diagnoses. Atypical sexual behaviors during sleep were associated with feelings of guilt, shame, and depression. Because of these feelings, patients and bed partners often tolerated the abnormal behavior for long periods of time without seeking medical attention. The following pathologic sleep disorders were demonstrated on polysomnography: partial complex seizures, sleep-disordered breathing, stage 3 to 4 non-rapid eye movement (REM) sleep parasomnias, and REM sleep behavior disorder. These findings were concurrent with morning amnesia. The atypical behaviors were related to different syndromes despite the similarity of complaints from bed partners. In most cases the disturbing and often harmful symptoms were controlled when counseling was instituted and sleep disorders were treated. In some cases treatment of seizures or psychiatric disorders was also needed. Clonazepam with simultaneous psychotherapy was the most common successful treatment combination. The addition of antidepressant or antiepileptic medications was required in specific cases.

Full Text Available Fibrous dysplasia is a disturbance of bone metabolism that is classified as a benign fibro-osseous lesion. Fibrous connective tissue, containing abnormal bone, replaces normal bone. The etiology of fibrous dysplasia is unknown. The radiographic appearance of the irregularly shaped trabeculae aids in the differential diagnosis. Occurring most commonly in the second decade of life, the lesions of fibrous dysplasia can be surgically recontoured for esthetic or functional purposes once they become dormant. Here, we report a case of bilateral fibrous dysplasia in a 7 year old male patient and its diagnostic work-up.

The objectives of this study were to define the clinical syndrome of retinal dysplasia and persistent primary vitreous in Miniature Schnauzer dogs and determine the etiology. We examined 106 Miniature Schnauzers using a biomicroscope and indirect ophthalmoscope. The anterior and posterior segments of affected dogs were photographed. Four enucleated eyes were examined using routine light microscopy and scanning electron microscopy. A pedigree was constructed and related dogs were test-bred to define the mode of inheritance of this syndrome. Congenital retinal dysplasia was confirmed in 24 of 106 related Miniature Schnauzer dogs. Physical and postmortem examinations revealed that congenital abnormalities were limited to the eyes. Biomicroscopic, indirect ophthalmoscopic, and neuro-ophthalmic examinations confirmed that some of these dogs were blind secondary to bilateral retinal dysplasia and detachment (nonattachment) (n = 13), and the remainder had generalized retinal dysplasia (n = 11). Fifteen of these dogs were also diagnosed with unilateral (n = 9) or bilateral (n = 6) persistent hyperplastic primary vitreous. Nutritional, infectious, or toxic etiologies were not evident on physical, postmortem, light microscopic, or transmitting and scanning electron microscopic examination of four affected Miniature Schnauzers. We examined the pedigree and determined that an autosomal recessive mode of inheritance was most likely. Three test-bred litters including those from affected parents, carrier and affected parents, and carrier parents confirmed this mode of inheritance. This study confirms that retinal dysplasia and persistent hyperplastic primary vitreous is a congenital abnormality that is inherited as an autosomal recessive condition in Miniature Schnauzers.

Can a more detailed evaluation of excision margins refine cytologic follow-up of women post-LLETZ for high-grade dysplasia?

LENUS (Irish Health Repository)

Treacy, Ann

2010-09-01

The relationship between dysplastic changes in the cervical epithelium and progression to in situ carcinoma and invasive carcinoma has been extensively studied. The removal of dysplastic epithelium through the long loop excision of the transformation zone (LLETZ) in 95% of the cases is curative. About 18% to 37% of LLETZ specimens with dysplasia at the margins have recurrent\\/residual disease. Earlier small studies suggest that the degree of dysplasia at the margins could predict for recurrence and allow a risk-based stratification of follow-up. We tested this hypothesis in a large group of women post-LLETZ for high-grade dysplasia with follow-up histology and cytology over a 12-year period. The cases were divided according to the excision margin status for dysplasia and if positive, low-grade or high-grade dysplasia. The groups were compared to assess whether the LLETZ specimens\\' margin status had an impact on the subsequent cytology or histology results. Positive follow-up results were defined as any grade of dysplasia in cytology or histology. Two thousand three hundred twenty-one women had LLETZs containing high-grade dysplasia over the 12-year period. One thousand five hundred thirty-four (66.1%) women had full histology and cytology follow-up available. Eight hundred twenty (53.4%) LLETZ specimens had positive margins and 714 (46.6%) had negative margins. The grade of dysplasia at the margins was available in 796 cases (97%) with 115 (15%) showing low-grade dysplasia and 680 (85%) high-grade dysplasia. One hundred seventy (20.7%) of the specimens with positive margins had positive follow-up results compared with 105 (14.7%) of the specimens with negative margins. The presence of dysplasia at an LLETZ margin is associated with dysplasia on follow-up cytology and histology (P=0.0021); however, the grade of dysplasia at the excision margin is not predictive of recurrent\\/residual dysplasia.

Full Text Available Cleidocranial dysplasia (CCD, is an autosomal dominant disorder with a prevalence of 1 in 1,000,000 individuals. It is generally characterized by orofacial manifestations, including enamel hypoplasia, retained primary teeth, and impacted permanent and supernumerary teeth. The successful treatment involving a timing intervention (orthodontic-maxillofacial surgeons-restorative is already described. However, the restorative treatment might improve the aesthetic final result in dentistry management for patients with cleidocranial dysplasia. Objective. Therefore, this clinical report presents a conservative restorative management (enamel microabrasion, dental bleaching, and direct composite resin for aesthetic solution for a patient with CCD. Clinical Considerations. The cosmetic remodeling is a conservative, secure, and low cost therapy that can be associated with other procedures such as enamel microabrasion and dental bleaching to achieve optimal outcome. Additionally, the Golden Proportion can be used to guide dental remodeling to improve the harmony of the smile and the facial composition. Conclusions. Thus, dentists must know and be able to treat dental aesthetic problems in cleidocranial dysplasia patients. The intention of this paper is to describe a restorative approach with the cosmetic remodeling teeth (by grinding or addicting material associated with enamel microabrasion and dental bleaching to reestablish the form, shape, and color of smile for patients with cleidocranial dysplasia.

Patients with skeletal dysplasia frequently require surgery. This patient population has an increased risk for peri-operative complications related to the anatomy of their upper airway, abnormalities of tracheal-bronchial morphology and function; deformity of their chest wall; abnormal mobility of their upper cervical spine; and associated issues with general health and body habitus. Utilizing evidence analysis and expert opinion, this study aims to describe best practices regarding the peri-operative management of patients with skeletal dysplasia. A panel of 13 multidisciplinary international experts participated in a Delphi process that included a thorough literature review; a list of 22 possible care recommendations; two rounds of anonymous voting; and a face to face meeting. Those recommendations with more than 80% agreement were considered as consensual. Consensus was reached to support 19 recommendations for best pre-operative management of patients with skeletal dysplasia. These recommendations include pre-operative pulmonary, polysomnography; cardiac, and neurological evaluations; imaging of the cervical spine; and anesthetic management of patients with a difficult airway for intubation and extubation. The goals of this consensus based best practice guideline are to provide a minimum of standardized care, reduce perioperative complications, and improve clinical outcomes for patients with skeletal dysplasia. © 2017 Wiley Periodicals, Inc.

Directory of Open Access Journals (Sweden)

Xueqing Chen

Full Text Available The aim of this study is to survey and compare the development of auditory skills in young children with Mondini dysplasia and profoundly-deaf young children with radiologically normal inner ears over a period of 3 years after cochlear implantation. A total of 545 young children (age 7 to 36 months with prelingual, severe to profound hearing loss participated in this study. All children received cochlear implantation. Based on whether or not there was a Mondini dysplasia as diagnosed with CT scanning, the subjects were divided into 2 groups: (A 514 young children with radiologically normal inner ears and (B 31 young children with Mondini dysplasia. The Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS was used to assess the children's auditory skills that include vocalization changes, spontaneous alerting to sounds in everyday living environments, and the ability to derive meaning from sounds. The assessment was performed prior to surgery and at 1, 3, 6, 9, 12, 24, and 36 months after implant device switch-on. The mean scores for overall auditory skills were not significantly different between groups A and B at pre-surgery, 1, 12, 24, and 36 months post-surgery, but were significantly different at 3, 6, and 9 months post-surgery. The mean scores for all auditory skills in children with Mondini dysplasia showed significant improvement over time. The mean scores for the three subcategories of auditory skills in children with Mondini dysplasia also showed significant differences at pre-surgery, 1, 3, 6, and 9 months, however, there were no significant differences at 12, 24, and 36 months. Overall, the auditory skills of young children with Mondini dysplasia developed rapidly after cochlear implantation, in a similar manner to that of young children with radiologically normal inner ears. Cochlear implantation is an effective intervention for young children with Mondini dysplasia.

Cemento-osseous dysplasia is a jaw disorder characterized by a reactive process in which normal bone is replaced by connective tissue matrix. There are different Cemento-osseous dysplasia entities. The treatment of these lesions, once diagnosed by radiology, is not required because generally they are asymptomatic. The localization is in the tooth-bearing areas of the jaws and its distribution is symmetric. In this case report, a 57-year-old Caucasian female patient was referred to our attention complaining of painful inflammatory events localized in the right angle of the jaw. The radiographic appearance, the distribution of several lesions and the positive vitality test of the involved teeth, supported the diagnosis of Florid Cemento-osseous dysplasia. Because of the symptomatology, the patient was submitted to surgery and the lesion and the second inferior right molar were removed. The histological examination of the specimens confirmed the diagnosis. Many lesions that may exhibit a similar sclerotic appearance on conventional radiographs have to be differentiated and dental imaging can be used to discriminate between Florid COD and other lesions. Diagnosis of Florid Cemento-osseous dysplasia can be made with accurate clinical and radiographic assessment. In asymptomatic cases no treatment is required and the patient should have regular follow-up, but in this symptomatic case it was necessary to proceed with surgical intervention. The surgery treatment in the symptomatic case had a favourable prognosis and the two years follow-up has shown a complete healing. Given the abow, it is concluded that the choice of treatment must be selective according to the disease sites. Key words: Cemento-ossifying dysplasia, fibro-osseous lesions, florid cemento-osseous dysplasia, cementoma.

1999-01-01

We report on a female fetus of 24 weeks whose clinical and radiological findings were compatible with boomerang dysplasia (BD). However, histopathology was unusual with a lateral fan shaped diaphyseal ossification. This has never been described either in typical atelosteogenesis I (AT-I) or in BD. The purpose of this report is to find out if this condition is a separate lethal bone dysplasia or another histological feature of the nosological group of AT-I and BD.

Skeletal dysplasias related to genetic etiologies have rarely been reported for past populations. This report presents the skeletal characteristics of an individual with dwarfism-related skeletal dysplasia from South Korea. To assess abnormal deformities, morphological features, metric data, and computed tomography scans are analyzed. Differential diagnoses include achondroplasia or hypochondroplasia, chondrodysplasia, multiple epiphyseal dysplasia, thalassemia-related hemolytic anemia, and lysosomal storage disease. The diffused deformities in the upper-limb bones and several coarsened features of the craniofacial bones indicate the most likely diagnosis to have been a certain type of lysosomal storage disease. The skeletal remains of EP-III-4-No.107 from the Eunpyeong site, although incomplete and fragmented, provide important clues to the paleopathological diagnosis of skeletal dysplasias.

Cemento-osseous dysplasias are a group of disorders known to originate from periodontal ligament tissue and involve, essentially, the same pathological process. They are usually classified into three main groups: periapical, florid, and focal cemental dysplasias depending on their extent and radiographic appearances. Radiographically, florid cementoosseous dysplasia (FCOD) appears as dense, lobulated masses, often symmetrically located in various regions of the jaws. The best management for the asymptomatic FCOD patient consists of regular recall examinations with prophylaxis. The management of the symptomatic patient is more difficult. A case of FCOD occurring in a 52-year-old edentulous Korean female is reported which is rare with regard to race and sex.

Ectodermal dysplasia encompasses more than 200 clinically distinct entities, which affect at least two structures derived from the ectoderm, including the skin, hair, nails, teeth, sweat glands, and sebaceous glands. X-linked hypohidrotic ectodermal dysplasia is the most common type and is caused by mutation of the EDA gene that encodes Ectodysplasin-A. It occurs in less than 1 in 100 000 individuals and is clinically characterized by hypodontia, hypohidrosis, hypotrichosis, and eye dis orders. We present a child evaluated in a multidisciplinary manner with clinical and molecular diagnosis of X-linked hypohidrotic ectodermal dysplasia with type missense mutation c.1133C> T; p.T378M in EDA gene.

Full Text Available In Sweden, where screening ends at the age of 60, about 30% of the cervical cancer cases occur in women older than 60. The aim of the present study was to investigate the prevalence of HPV and cervical dysplasia in women of 60 years and above.From September 2013 until June 2015, 1051 women aged 60-89 years (mean 68 years were sampled for an HPV test when attending an outpatient gynecology clinic. Women with positive results had a second HPV test and liquid based cytology (LBC, after 3.5 months on average. Those with a positive second HPV test were examined by colposcopy, and biopsy and a sample for LBC was obtained.The prevalence of HPV was 4.1%, (95%CI 3.0-5.5, n = 43 at the first test, and at the second test 2.6% remained positive (95%CI 1.7-3.8, n = 27. The majority of women positive in both HPV tests, had dysplasia in histology, 81.5% (22/27 (4 CIN 2-0.4%, 18 CIN 1-1.7%. HPV-related dysplasia was found in 2.1%, (95%CI 1.3-3.2, n = 22 of the 1051 women. Four of the 22 women with positive HPV tests also had abnormal cytology, one ASCUS and three CIN 1. No cancer or glandular dysplasia was detected.A significant proportion of elderly women were found to have a persistent cervical HPV infection. Among them there was a high prevalence of CIN diagnosed by histology. The HPV test showed high sensitivity and specificity in detecting CIN in elderly women, while cytology showed extremely low sensitivity.

Dysplasia within sessile serrated polyps (SSPs) is difficult to detect and may be mistaken for an adenoma, risking incomplete resection of the background serrated tissue, and is strongly implicated in interval cancer after colonoscopy. The use of endoscopic imaging to detect dysplasia within SSPs has not been systematically studied. Consecutively detected SSPs ≥8 mm in size were evaluated by using a standardized imaging protocol at a tertiary-care endoscopy center over 3 years. Lesions suspected as SSPs were analyzed with high-definition white light then narrow-band imaging. A demarcated area with a neoplastic pit pattern (Kudo type III/IV, NICE type II) was sought among the serrated tissue. If this was detected, the lesion was labeled dysplastic (sessile serrated polyp with dysplasia); if not, it was labeled non-dysplastic (sessile serrated polyp without dysplasia). Histopathology was reviewed by 2 blinded specialist GI pathologists. A total of 141 SSPs were assessed in 83 patients. Median lesion size was 15.0 mm (interquartile range 10-20), and 54.6% were in the right side of the colon. Endoscopic evidence of dysplasia was detected in 36 of 141 (25.5%) SSPs; of these, 5 of 36 (13.9%) lacked dysplasia at histopathology. Two of 105 (1.9%) endoscopically designated non-dysplastic SSPs had dysplasia at histopathology. Endoscopic imaging, therefore, had an accuracy of 95.0% (95% confidence interval [CI], 90.1%-97.6%) and a negative predictive value of 98.1% (95% CI, 92.6%-99.7%) for detection of dysplasia within SSPs. Dysplasia within SSPs can be detected accurately by using a simple, broadly applicable endoscopic imaging protocol that allows complete resection. Independent validation of this protocol and its dissemination to the wider endoscopic community may have a significant impact on rates of interval cancer.

Epileptogenicity of cortical dysplasia in temporal lobe dual pathology: an electrophysiological study with invasive recordings.

Science.gov (United States)

Fauser, Susanne; Schulze-Bonhage, Andreas

2006-01-01

Hippocampal sclerosis is often associated with macroscopic or microscopic dysplasia in the temporal neocortex (TN). The relevance of such a dual pathology with regard to epileptogenesis is unclear. This study investigates the role of both pathologies in the generation of ictal and interictal activity. Ictal (113 seizures) and interictal data from invasive EEG recordings with simultaneous depth electrodes in the hippocampus and subdural electrodes over the TN were analysed retrospectively in 12 patients with variable degrees of hippocampal sclerosis and different types of histologically confirmed temporal cortical dysplasia [all male, age at epilepsy onset 25 Hz) and repetitive sharp waves. The interictal patterns over the TN were similar to those seen over extratemporal focal cortical dysplasias. Simultaneous recordings from the hippocampus and the TN strongly suggest that dysplastic tissue in the TN is often epileptogenic. The quantitative contribution of the hippocampus to seizure generation corresponded with the degree of hippocampal pathology, whereas different subtypes of cortical dysplasia did not affect its relative contribution to seizure generation and even mild forms of dysplasia were epileptogenic.

2018-01-01

Cleidocranial dysplasia is a type of skeletal dysplasia, which is primarily characterized by delayed ossification of skeletal structures. It causes facial and oral abnormalities, resulting in difficult airway management and neuraxial anesthesia. The patient was a 24-year-old primipara (height 138 cm, weight 42 kg) with a hypoplastic right clavicle, patent fontanelles, dental malalignment, and a high palate. She was diagnosed with cleidocranial dysplasia at birth, although gene examination has not been performed. The fetus was confirmed to have short limbs and large fontanelles during an examination performed at 28 weeks gestation, suspected to have cleidocranial dysplasia. The mother was scheduled for a cesarean section at 37 weeks and 1 day due to cephalopelvic disproportion. Preoperative radiography and magnetic resonance imaging revealed no vertebral and spinal abnormalities, which allowed combined spinal-epidural analgesia (CSEA) to be performed. The surgery was safely concluded under CSEA with no intraoperative respiratory or circulatory problems. Patients with cleidocranial dysplasia exhibit facial, oral abnormalities, and often vertebral abnormalities. Imaging assessments before neuraxial anesthesia and careful preparation for airway management are required.

Molecular genetic analysis of consanguineous Pakistani families with autosomal recessive hypohidrotic ectodermal dysplasia.

Bibi, Nosheen; Ahmad, Saeed; Ahmad, Wasim; Naeem, Muhammad

2011-02-01

Hypohidrotic ectodermal dysplasia is an inherited disorder characterized by defective development of teeth, hairs and sweat glands. X-linked hypohidrotic ectodermal dysplasia is caused by mutations in the EDA gene, and autosomal forms of hypohidrotic ectodermal dysplasia are caused by mutations in either the EDAR or the EDARADD genes. To study the molecular genetic cause of autosomal recessive hypohidrotic ectodermal dysplasia in three consanguineous Pakistani families (A, B and C), genotyping of 13 individuals was carried out by using polymorphic microsatellite markers that are closely linked to the EDAR gene on chromosome 2q11-q13 and the EDARADD gene on chromosome 1q42.2-q43. The results revealed linkage in the three families to the EDAR locus. Sequence analysis of the coding exons and splice junctions of the EDAR gene revealed two mutations: a novel non-sense mutation (p.E124X) in the probands of families A and B and a missense mutation (p.G382S) in the proband of family C. In addition, two synonymous single-nucleotide polymorphisms were also identified. The finding of mutations in Pakistani families extends the body of evidence that supports the importance of EDAR for the development of hypohidrotic ectodermal dysplasia. © 2010 The Authors.

Mondini's dysplasia is a developmental anomaly of the middle ear characterized by cochlear malformation with dilation of the vestibular aquaduct, vestibule, and ampullar ends of the semicircular canals. These deformities may result in a connection between subarachnoid space and the middle ear resulting in recurrent episodes of meningitis. Additionally, it is commonly associated with hearing impairment. We describe here a boy with recurrent meningitis and unilateral sensorineural hearing loss. Mondini dysplasia was demonstrated with computed tomographic scans of the temporal bones in the search for pathogenesis of recurrent meningitis.

Bani, Mehmet; Tezkirecioglu, Ali Melih; Akal, Nese; Tuzuner, Tamer

2010-01-01

Ectodermal dysplasia is a hereditary disorder that occurs as a consequence of disturbances in the ectoderm of the developing embryo. The triad of nail dystrophy, alopecia or hypotrichosis and palmoplantar hyperkeratosis is usually accompanied by a lack of sweat glands and a partial or complete absence of primary and/or permanent dentition. Two case reports illustrating the prosthetic rehabilitation of 2 young boys with anhidrotic ectodermal dysplasia associated with severe anodontia are presented. Since the oral rehabilitation of these cases is often difficult; particularly in pediatric patients, treatment should be administered by a multidisciplinary team involving pediatric dentistry, orthodontics, prosthodontics and oral-maxillofacial surgery.

A 51 year old man with severe degenerative joint disease, short stature, barrel chest deformity, platyspondyly, a narrow pelvis, small iliac bones, dysplastic femoral heads and necks, notching of the patellae and flattening of the femoral intercondylar notches has been described as an example of Spondyloepiphyseal dysplasia tarda SDT. The entity was discussed in detail. The notching of the patellae has not been reported in association with SDT to the authors' knowledge. Characteristic features of SDT allow it to be differentiated from other arthropathies and dysplasias and these distinctions have been emphasized in the discussion. The diagnosis in this case can only be considered presumptively proved. (orig./MG)

We present a child with irregular ossification of tubular bone epiphyses, short bones, and spine. The radiographic evolution of bones undergoing endochondral ossification was followed from the age of 1 year 9 months to 6 years. The unusual features demonstrated in this child made classification difficult: pseudoachondroplasia was excluded because no mutations of the COMP gene were found. Considering the evolution of the radiographic appearances, the most likely diagnosis would seem to be an unusual form of spondyloepiphyseal dysplasia, mimicking some aspects of multiple epiphyseal dysplasia. Endochondral ossification was diffusely altered with a mixture of epiphyseal ossification delay associated with acceleration and early fusion. This case was a unique presentation within the family, suggesting a mutation in the affected child. (orig.)

The unusual features demonstrated in this child made classification difficult: pseudoachondroplasia was excluded because no mutations of the COMP gene were found. Considering the evolution of the radiographic appearances, the most likely diagnosis would seem to be an unusual form of spondyloepiphyseal dysplasia, mimicking some aspects of multiple epiphyseal dysplasia. Endochondral ossification was diffusely altered with a mixture of epiphyseal ossification delay associated with acceleration and early fusion. This case was a unique presentation within the family, suggesting a mutation in the affected child. (orig.)

Full Text Available Abstract Aims The aim of this study was to find out the characteristic morphology of malignant atypical cells which were missed on routine cytology of urine. Materials and methods In this retrospective study, we examined detailed cytomorphology of 18 cases of atypical urinary cytology which were missed on routine examination and were further proved on histopathology as transitional cell carcinoma (TCC of bladder. The cytological features of these cases were compared with 10 cases of benign urine samples. Results There were 11 cases of high grade TCC and 7 cases of low grade TCC on histopathology of the atypical urine samples. Necrosis in the background and necrosed papillae were mostly seen in malignant atypical cells. The comet cells and cells with India ink nuclei (single cells with deep black structure-less nuclei were only observed in malignant atypical cells. The most consistent features in malignant atypical cells were: i high nuclear and cytoplasmic (N/C ratio ii nuclear pleomorphism iii nuclear margin irregularity iv hyperchromasia and v chromatin abnormalities Conclusion The present study emphasizes that nuclear features such as high N/C ratio, hyperchromasia and chromatin abnormalities are particularly useful for assessing the malignant atypical cells. Other cytological features such as comet cells and cells with India ink nuclei are also helpful for diagnosis but have limited value because they are less frequently seen.

Aim. Cemento-osseous dysplasia (COD) represents a rare group of benign fibroosseous disorders, while osteogenic sarcoma (OS) on the hand, is a malignant tumour of ominous prognosis. A combination of COD and OS is rare and sparsely reported in literature. There are only four reported cases known to the authors. The aim of this paper is to report additional cases of COD occurring concurrently with OS. Materials and Methods. The clinicoradiologic findings and histological analysis of mandibular lesions in two patients who reported at the Dental Centre of the University College Hospital, Ibadan, Nigeria, are presented. Results. The two patients were diagnosed of mandible osteosarcoma occurring concurrently with bilateral mandibular focal cemento-osseous dysplasia. Conclusion. The simultaneous occurrence of osteosarcoma and cemento-osseous dysplasia raises the question of whether COD has transformed into OS or a collision tumour has occurred and their simultaneous occurrence is just a coincidence.

Full Text Available Developmental dysplasia of the hip (DDH or congenital hip dysplasia (CDH is the most prevalent developmental childhood hip disorder. It includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. The natural history of neglected DDH in adults is highly variable. The mean age of onset of symptoms is 34.5 years for dysplastic DDH, 32.5 years for low dislocation, 31.2 years for high dislocation with a false acetabulum, and 46.4 years for high dislocation without a false acetabulum. Thorough understanding of the bony and soft tissue deformities induced by dysplasia is crucial for the success of total hip arthroplasty. It is important to evaluate the existing acetabular deformity three-dimensionally, and customize the correction in accordance with the quantity and location of ace tabular deficiencies. Acetabular reconstruction in patients with DDH is hallenging. Interpretation of published data is difficult and should be done with caution because most series include patients with different types of hip disease. In general, the complication rate associated with THA is higher in patients with hip dysplasia than it is in patients with osteoarthritis. Overall, clinical and functional outcomes following THA in patients hip dysplasia (DDH differ from those treated for primary hip osteoarthritis, possibly due to the lower age and level of activity. Although function scores decline with age, the scores for pain and range of motion presented with a statistically significant improvement in the long-term.

Objective : Ectrodactyly-ectodermal dysplasia-clefting syndrome is a congenital anomaly characterized by ectodermal dysplasia, ectrodactyly, cleft lip and palate, and lacrimal duct anomalies. Because this syndrome is frequently accompanied by a congenital lack of teeth, narrow palate, and malocclusion, comprehensive orthodontic intervention is required. Design : To highlight the specific dental and maxillofacial characteristics of ectrodactyly-ectodermal dysplasia-clefting syndrome, six Japanese individuals diagnosed with the syndrome are described here. Patients : The subjects consisted of two boys and four girls (age range, 6.0 to 13.9 years) diagnosed with ectrodactyly-ectodermal dysplasia-clefting syndrome by medical and dental specialists. Their conditions included ectodermal dysplasia (hypodontia, microdontia, enamel hypoplasia, and abnormalities in hair and nails), cleft lip and/or palate, and ectrodactyly. Cephalograms, panoramic x-rays, and dental casts were taken; systemic complications were recorded at the first visit to our dental hospital. Results : All individuals had severe oligodontia with 9 to 18 missing teeth. The missing teeth were mainly maxillary and mandibular incisors and second bicuspids, arranged in a symmetrical manner. Cephalometric analysis showed retruded and short maxilla due to cleft lip and/or palate. It is interesting that all individuals showed a characteristically shaped mandibular symphysis with a retruded point B. It is likely that this unusual symphyseal morphology is due to the lack of mandibular incisors. Conclusions : This study demonstrates the presence of severe oligodontia in the incisal and premolar regions and describes a characteristic maxillary and mandibular structure in Japanese individuals with ectrodactyly-ectodermal dysplasia-clefting syndrome.

Placental Mesenchymal Dysplasia: A Case Report

Full Text Available Introduction. A rare case of histologically proven placental mesenchymal dysplasia (PMD with fetal omphalocele in a 22-year-old patient is reported. Material and Methods. Antenatal ultrasound of this patient showed hydropic placenta with a live fetus of 17 weeks period of gestation associated with omphalocele. Cordocentesis detected the diploid karyotype of the fetus. Patient, when prognosticated, choose to terminate the pregnancy in view of high incidence of fetal and placental anomalies. Subsequent histopathological examination of placenta established the diagnosis to be placental mesenchymal dysplasia. Conclusion. On clinical and ultrasonic grounds, suspicion of P.M.D. arises when hydropic placenta with a live fetus presents in second trimester of pregnancy. Cordocentesis can detect the diploid karyotype of the fetus in such cases. As this condition is prognostically better than triploid partial mole, continuation of pregnancy can sometimes be considered after through antenatal screening and patient counseling. However, a definite diagnosis of P.M.D. is made only on placental histology by absence of trophoblast hyperplasia and trophoblastic inclusions.

The spondylo and spondylometaphyseal dysplasias (SMDs) are characterized by vertebral changes and metaphyseal abnormalities of the tubular bones, which produce a phenotypic spectrum of disorders from the mild autosomal-dominant brachyolmia to SMD Kozlowski to autosomal-dominant metatropic dysplasia. Investigations have recently drawn on the similar radiographic features of those conditions to define a new family of skeletal dysplasias caused by mutations in the transient receptor potential cation channel vanilloid 4 (TRPV4). This review demonstrates the significance of radiography in the discovery of a new bone dysplasia family due to mutations in a single gene. (orig.)

Background. ''Metatropic dysplasia variants'' are a group of bone dysplasias whose skeletal abnormalities are similar to, but milder than, those of classical metatropic dysplasia. The genetic and phenotypic heterogeneity has not been thoroughly elucidated. Objective. The objective was to designate a distinct subtype of these metatropic dysplasia variants. Materials and methods. The subjects were four Japanese patients, two sporadic cases and two siblings, who all had identical skeletal changes. The radiological features in these patients were compared with those of previously reported metatropic dysplasia variants. Results. Moderate platyspondyly with pear-shaped and/or anterior-tongued vertebral bodies, halberd pelvis, and dumbbell deformity of the tubular bones were regarded as hallmarks of metatropic dysplasia variants. The peculiar skeletal change in our patients was advanced carpal skeletal age in childhood, unlike most patients reported as metatropic dysplasia variants who manifest delayed carpal ossification. Another hallmark was congenital dislocation of the radial heads. A description of a patient with similar skeletal changes was found in the literature. Conclusion. These patients are considered to represent a distinct subgroup of metatropic dysplasia variants. It remains unknown whether the present siblings represent an autosomal recessive trait or an autosomal dominant trait with germinal mosaicism related to increased paternal age. (orig.)

Radiofrequency ablation of Barrett's esophagus with low-grade dysplasia is recommended in recent American College of Gastroenterology guidelines, with endoscopic surveillance considered a reasonable alternative. Few studies have directly compared outcomes of radiofrequency ablation to surveillance and those that have are limited by short duration of follow-up. This study aims to compare the long-term effectiveness of radiofrequency ablation versus endoscopic surveillance in a large, longitudinal cohort of patients with Barrett's esophagus, and low-grade dysplasia.We conducted a retrospective analysis of patients with confirmed low-grade dysplasia at a single academic medical center from 1991 to 2014. Patients progressing to high-grade dysplasia or esophageal adenocarcinoma within one year of index LGD endoscopy were defined as missed dysplasia and excluded. Risk factors for progression were assessed via Cox proportional hazards model. Comparison of progression risk was conducted using a Kaplan-Meier analysis. Subset analyses were conducted to examine the effect of reintroducing early progressors and excluding patients diagnosed prior to the advent of ablative therapy. Of 173 total patients, 79 (45.7%) underwent radiofrequency ablation while 94 (54.3%) were untreated, with median follow up of 90 months. Seven (8.9%) patients progressed to high-grade dysplasia or adenocarcinoma despite ablation, compared with 14 (14.9%) undergoing surveillance (P = 0.44). This effect was preserved when patients diagnosed prior to the introduction of radiofrequency ablation were excluded (8.9% vs 13%, P = 0.68). Reintroduction of patients progressing within the first year of follow-up resulted in a trend toward significance for ablation versus surveillance (11.1% vs 23.8%, P = 0.053).In conclusion, progression to high-grade dysplasia or adenocarcinoma was not significantly reduced in the radiofrequency ablation cohort when compared to surveillance. Despite recent studies

Early detection of oral squamous cell carcinoma (OSCC) remains one of the most efficient ways to ensure patient survival and improved quality of life. Although specific biomarkers related to OSCC have been investigated, a useful biomarker that assesses the transition potential of potentially malignant lesion to OSCC remains to be found. Osteopontin (OPN) has been recognized as an important factor in tumorigenesis and their expression in OSCC have been investigated earlier. In the present study, evaluation of OPN expression in premalignant and malignant lesions has been carried out to assess their possible role as a biomarker in the early diagnosis and prognosis of OSCC. The objective of this study is to evaluate the role of OPN as a biomarker in the diagnosis and prognosis of OSCC. The study group consisted of archival paraffin-embedded blocks of ten cases each of varying grades of OSCC, oral epithelial dysplasias and epithelial hyperplasias. Sections were subjected to immunohistochemical staining for the biomarker OPN. A positive OPN expression was noticed in epithelial dysplasias and SCC arising from the oral epithelium. A progressive increase in the intensity of staining was seen with increasing grades of dysplasias and a decrease in OPN expression with an increase in grades was observed in OSCC. The expression of OPN in full thickness of epithelium in severe dysplasias, carcinoma in situ, and in the superficial epithelium of OSCC suggest the possibility of considering OPN expression in full epithelial thickness in dysplasias as an indicator for malignant transformation.

Central ossifying fibroma, periapical cemento-osseous dysplasia and complex odontoma occurring in the same jaw

Full Text Available Central ossifying fibroma is a rare, benign fibro-osseous lesion that arises from the periodontal ligament. Periapical cemento-osseous dysplasia is another variant of fibro-osseous lesion which occurs in the anterior region of the mandible of females. Odontoma is a benign odontogenic tumor that contains enamel, dentine cement and pulp tissue. A 46-year-old woman was referred to the Department of Oral Medicine, School of Dentistry, Tehran University of Medical Sciences, with two nonpainful swellings on both sides of the mandible, which had been slowly growing over a period of one year. Our differential diagnosis was florid cemento-osseous dysplasia, focal cemento-osseous dysplasia for the right side, complex odontoma for the left side and periapical cement-osseous dysplasia for the anterior side. The historical feature revealed ossifying fibroma, complex odontoma and periapical cemento-osseous dysplasia. The occurrence of these three lesions in the same jaw has been rarely reported in the literature. The relationship between the occurrence of these three lesions is not obvious it could be coincidental. It seems that more case reports are needed to establish the relationship between them.

Francisella tularensis is a gram-negative coccobacillus that causes a condition commonly referred to as tularemia. There has been a dramatic increase in tularemia cases reported in South Dakota, many of which were challenging to diagnose due to atypical clinical manifestations. We describe an interesting case of pneumonic tularemia and summarize six similar cases, several of which presented with lung nodules suggestive of malignancy. According to the literature, this is only the third outbreak of pneumonic tularemia reported in the U.S. We believe it is important for clinicians to be aware of the increased incidence of tularemia in the area and to be vigilant in the diagnosis and management of these atypically presenting cases.

Full Text Available Musculoskeletal system is a complex assembly of tissues which acts as scaffold for the body and enables locomotion. It is often overlooked that different components of this system may biomechanically interact and affect each other. Skeletal dysplasias are diseases predominantly affecting the development of the osseous skeleton. However, in some cases skeletal dysplasia patients are referred to neuromuscular clinics prior to the correct skeletal diagnosis. The muscular complications seen in these cases are usually mild and may stem directly from the muscle defect and/or from the altered interactions between the individual components of the musculoskeletal system. A correct early diagnosis may enable better management of the patients and a better quality of life. This paper attempts to summarise the different components of the musculoskeletal system which are affected in skeletal dysplasias and lists several interesting examples of such diseases in order to enable better understanding of the complexity of human musculoskeletal system.

Despite advances in antenatal imaging and genetic techniques, post-delivery post-mortem foetal radiography remains the key investigation in accurate diagnosis of skeletal dysplasia manifesting in the foetus. Foetal radiography is best performed using pathology-specimen radiography equipment and is often carried out in the pathology department without involvement of the radiology unit. However, paediatric radiologists may be asked to interpret post-mortem foetal radiographs when an abnormality is suspected. Many foetal radiographs are carried out before 20 weeks' gestation, and the interpreting radiologist needs to be familiar with the range of normal post-mortem foetal appearances at different gestational ages, as well as the appearances of some of the more commonly presenting skeletal dysplasias, and will benefit from a systematic approach when assessing more challenging cases. In this pictorial essay, we illustrate various normal post-mortem foetal radiographic appearances, give examples of commonly occurring skeletal dysplasias, and describe an approach to establishing more difficult diagnoses.

In the nosological structure of renovascular hypertensions fibromuscular dysplasia of the renal arteries by incidence ranks second after atherosclerosis. The illness affects mainly women, more frequently young and having borne a child. Hypertension in such patients is usually characterized by high values of the diastolic pressure, and leads to early neurologic complaints such as headache, sight impairment, vertigo and Meniere-like syndromes. Morphological and functional changes are likewise described. Some of the literature statements concerning the etiopathogenesis and classification of fibromuscular dysplasia are critically assayed. The success of the surgical management depends on the timely established exact diagnosis, and angiography appears to be the only method of primary importance in this respect.

Mondini dysplasia, also known as Mondini malformation, is a developmental abnormality of the inner and middle ears that can cause hearing loss, cerebrospinal fluid (CSF) leakage, and recurrent bacterial meningitis (RBM), which is defined as two or more episodes of meningitis separated by a period of convalescence and the complete resolution of all signs and symptoms. An accurate diagnosis of the underlying pathology is crucial to prevent further episodes from occurring. Herein, we present a three-year-old boy with RBM and unilateral sensorineural hearing loss. During the evaluation to determine the etiology of the RBM, cystic malformation in the cochlea and vestibular dilatation consistent with Mondini dysplasia were detected via computerized tomography (CT) of the temporal bone.

Through August 2013, 105 cases of intracranial extraventricular neurocytoma (EVN) had been described; 6% were located in cerebellum and 22% were atypical EVN. A rare morphologic form of neurocytoma, atypical EVN has had only 24 cases reported to date. Its prognosis is poorer than the typical central neurocytoma. This case report describes an atypical cerebellar EVN, a form that has not been reported yet, hence the interest of this article. We emphasise its cystic nature and mural nodule, in an infrequent presentation. EVN are low-incidence tumours that we need to take into consideration when making the differential diagnosis of cystic cerebellar lesions with mural nodule. Given that the prognosis of atypical EVNs depends on the atypical nature and on the grade of resection, medical follow up has to be more constant, due to the greater degree of recurrence.

Mechanical ventilation is an important potentially modifiable risk factor for the development of bronchopulmonary dysplasia. Effective use of noninvasive respiratory support reduces the risk of lung injury. Lung volume recruitment and avoidance of excessive tidal volume are key elements of lung-protective ventilation strategies. Avoidance of oxidative stress, less invasive methods of surfactant administration, and high-frequency ventilation are also important factors in lung injury prevention. Copyright © 2015 Elsevier Inc.

The tongue squamous cell carcinomas (SCCs) are characterized by high mitotic activity, and early detection is desirable. Overexpression of the DNA replication-initiation proteins has been associated with dysplasia and malignancy. Our aim was to determine whether these proteins are useful biomarkers for assessing the development of tongue SCC. We analyzed the mRNA expression of CDC6, CDT1, MCM2 and CDC45 in formalin-fixed, paraffin-embedded benign and malignant tongue tissues using quantitative real-time PCR followed by statistical analysis. We found that the expression levels are significantly higher in malignant SCC than mild precancerous epithelial dysplasia, and the expression levels in general increase with increasing grade of precancerous lesions from mild, moderate to severe epithelial dysplasia. CDC6 and CDC45 expression is dependent of the dysplasia grade and lymph node status. CDT1 expression is higher in severe dysplasia than in mild and moderate dysplasia. MCM2 expression is dependent of the dysplasia grade, lymph node status and clinical stage. The expression of the four genes is independent of tumor size or histological grade. A simple linear regression analysis revealed a linear increase in the mRNA levels of the four genes from the mild to severe dysplasia and SCC. A strong association was established between CDC6 and CDT1, and between MCM2 and CDC45 expression. The nonparametric receiver operating characteristic analysis suggested that MCM2 and CDC45 had a higher accuracy than CDC6 and CDT1 for distinguishing dysplasia from tongue SCC. These proteins can be used as biomarkers to distinguish precancerous dysplasia from SCC and are useful for early detection and diagnosis of SCC as an adjunct to clinicopathological parameters

To investigate the difference in amide proton transfer (APT)-weighted signals between benign and atypical meningiomas and determine the value of APT imaging for differentiating the two. Fifty-seven patients with pathologically diagnosed meningiomas (benign, 44; atypical, 13), who underwent preoperative MRI with APT imaging between December 2014 and August 2016 were included. We compared normalised magnetisation transfer ratio asymmetry (nMTR{sub asym}) values between benign and atypical meningiomas on APT-weighted images. Conventional MRI features were qualitatively assessed. Both imaging features were evaluated by multivariable logistic regression analysis. The discriminative value of MRI with and without nMTR{sub asym} was evaluated. The nMTR{sub asym} of atypical meningiomas was significantly greater than that of benign meningiomas (2.46% vs. 1.67%; P < 0.001). In conventional MR images, benign and atypical meningiomas exhibited significant differences in maximum tumour diameter, non-skull base location, and heterogeneous enhancement. On multivariable logistic regression analysis, high nMTR{sub asym} was an independent predictor of atypical meningiomas (adjusted OR, 11.227; P = 0.014). The diagnostic performance of MRI improved with nMTR{sub asym} for predicting atypical meningiomas. Atypical meningiomas exhibited significantly higher APT-weighted signal intensities than benign meningiomas. The discriminative value of conventional MRI improved significantly when combined with APT imaging for diagnosis of atypical meningioma. (orig.)

Full Text Available Purpose: to analyze and scientifically substantiate peculiarities of cause-effect relationship of hip dysplasia in pre-school children. Material and Methods: analysis and systematization of scientific and methodological literature, medical histories, anamneses, interviews and questionings. Results: it is specified that failure to timely identify and eliminate the symptoms of hip dysplasia in pre-school children leads to negative consequences, namely limited amplitude of hip joint movements; lower limp muscle weakness; valgus and varus deformations of lower limp; increasing of L-lordosis; skewness of hip bones; scoliosis; claudication. Conclusions: the modern state of the problem of hip dysplasia in pre-school children is analyzed. The cause-effect relationship is defined, their mutual transition is projected. All cause-effect relationships are in direct proportion and in constant interaction: the cause the forms effect and the effect influences the cause

Ectodermal dysplasia is a rare congenital disease that affects several structures of ectodermal origin. The most commonly related oral characteristics are hypodontia, malformed teeth and underdeveloped alveolar ridges. New alternative treatments are needed due to the failure of the conventional prosthesis retention. This case report outlines the oral rehabilitation treatment of a 9-year-old girl with ectodermal dysplasia. The treatment was performed with conventional prosthesis upon mini-implants. The mini-implants provided prosthetic retention. The patient reported a good adaptation of the dental prosthesis and satisfaction with the treatment. The increased self-esteem improved the socialization skills of the girl. In this case report, use of prosthesis with mini-implants was satisfactory for prosthetic retention. However, clinical studies with long-term follow-up are needed to test the mini-implants as an alternative for oral rehabilitation of children with ectodermal dysplasia.

Full Text Available Ectodermal dysplasias are rare conditions with a triad of hypotrichosis, anodontia and anhidrosis. In literature review there have been only a few reports of anesthetic management of patients with ectodermal dysplasias. Hyperthermia is a very serious risk which may occur due to the defect of sweat glands. The present case involves a 10-year-old child with ectodermal dysplasia who presented with an acute abdomen and was considered for an emergency surgery. Our aim was to demonstrate the successful management of this case using a combination of general and epidural anesthesia. It is important for anesthesiologist to have information about this syndrome in case of emergency operations, since it can prevent serious complications and even save lives.

Full Text Available Introduction. When dealing with issues of access and planning of training and competitive pressures special interest cause the person with signs of connective tissue dysplasia.Aim. Improvement of medical support of training process of athletes with signs of connective tissue dysplasia.Materials and methods. 188 athletes are examined, including 59 with signs of connective tissue dysplasia. There are made the basic group. Signs of systemic involvement of connective tissue are determined using anthropometry and somatoscopy. An echocardiographic examination is conducted for all athletes at rest and during bicycle ergometry in regenerative period conducted.Results. Underweight body, acromacria, hypermobility of joints and flat feet are often observed with signs of systemic involvement of connective tissue.During veloergometry it was established deterioration of myocardial relaxation during diastole core group of athletes while performing load average power, which led to a drop in ejection fraction at submaximal levels of exertion.Conclusions. Existence of connective tissue dysplasia in athletes with different prognosis states requires sports physicians an in-depth analysis and differential diagnosis of clinical forms in order to prevent complications during training and competitive pressures. Early signs of cardiac strain while performing physical activity in athletes with signs of connective tissue dysplasia were symptoms of myocardial relaxation on indicators of diastolic heart function. Ejection fraction at rest remained at normal levels

The brain CTs of 54 endogenous psychotics (27 males, 27 females) who were less than 40 years of age and were first adimitted in Aichi Medical University from 1982 to 1986, and 20 controls (10 males, 10 females) were examined. Using Mitsuda's classification, we devided all the cases into 29 schizophrenics (18 males, 11 females) and 25 atypical psychotics (9 males, 16 females). In order to investigate the differences of CT findings between the two patient groups, the 3rd ventricle index (the ratio of 3rd ventricle width to the internal diameter of the skull), Evans'ratio, lateral ventricle brain ratio (VBR), Sylvian fissure to brain ratio, 4th ventricle to cerebellum ratio were determined. Schizophrenics had larger 3rd and lateral ventricles as well as Sylvian fissures when compared to controls, but atypical psychotics had not. Moreover, schizophrenics had larger 3rd and lateral ventricle than atypical psychotics. But in widths of Sylvian fissures there was no statistical significant difference between the two groups. Ventricle enlargements of schizophrenics did not correlate with duration of illness as well as age, and were not results of prior psychiatric treatment such as medication and EST. Therefore the following is suggested that, this abnormal CT findings predate the onset of schizophrenic psychoses. In atypical psychotics the changes of Sylvian fissures correlated with duration of illness, but not with age. Such observations may possibly suggest that recurrence of the illness might finally attain irreversible changes even in atypical psychotics. Finally, the heterogeneity of schizophrenia and the independence of atypical psychosis were also discussed. (author) 53 refs

Little data exists on the original morphology of acetabular dysplasia obtained from patients without radiographic advanced osteoarthritic changes. The aim of this study was to investigate the distribution and degree of acetabular dysplasia in a large number of patients showing no advanced degenerative changes using three-dimensional computed tomography (3DCT). Eighty-four dysplastic hips in 55 consecutive patients were studied. All 84 hips were in pre- or early osteoarthritis without radiographic evidence of joint space narrowing, formation of osteophytes or cysts, or deformity of femoral heads. The mean age at the time of CT scan was 35 years (range 15-64 years). 3D images were reconstructed and analyzed using recent computer imaging software (INTAGE Realia and Volume Player). Deficiency types and degrees of acetabular dysplasia were precisely evaluated using these computer software. The average Harris hip score at CT scans was 82 points. Twenty-two hips (26%) were classified as anterior deficiency, 17 hips (20%) as posterior deficiency, and 45 hips (54%) as lateral deficiency. No significant difference was found in the Harris hip score among these groups. The analysis of various measurements indicated wide variations. There was a significant correlation between the Harris hip score and the acetabular coverage (p < 0.001). Our results indicated wide variety of deficiency type and degree of acetabular dysplasia. Hips with greater acetabular coverage tended to have a higher Harris hip score. (orig.)

Chondroectodermal dysplasia (Ellis van Creveld syndrome: A report of three cases with review of literature

Directory of Open Access Journals (Sweden)

Kurian K

2007-01-01

Full Text Available Chondroectodermal dysplasia is a rare mesenchymal - ectodermal dysplasia first described in 1940 by Richard W.B. Ellis and Simon van Creveld now known as Ellis van Creveld syndrome. It is also known as Mesvectodermal dysplasia. Majority of cases were characteristically seen in one particular inbred population from the Amish community of Lancaster County, Pennsylvania, U.S.A. The syndrome manifests with several skeletal anomalies, oral mucosal and dental anomalies, congenital cardiac defects and nail dysplasia. Ellis van Creveld syndrome may be differentiated from other chondrodystrophies like achondroplasia, chondroplasia punctata, asphyxiating thorasic dystrophy and Morquio′s syndrome. The presence of oral mucosal and dental alterations like notching of the lower alveolar process, fusion of the upper lip with gingival mucosal margin, occasional presence of neonatal teeth, oligodontia and conical shape of anterior teeth will confirm the diagnosis of Ellis van Creveld syndrome and hence its importance to dentists.

The Use of Electroconvulsive Therapy in Atypical Psychotic Presentations

Vasu, Devi

2007-01-01

Convulsive therapy and its progeny, electroconvulsive therapy (ECT), were originally used for the treatment of catatonic schizophrenia, and there is little doubt that ECT remains an effective intervention for the treatment of schizophrenia. However, current practice tends to favor the use of ECT in severe or treatment refractory affective disorders, and its use in schizophrenia and other nonaffective (atypical) psychotic disorders has become controversial. Case reports have suggested a role for ECT in two specific atypical psychotic disorders: Cotard's syndrome and cycloid psychosis. In this article, we review the atypical psychotic disorders and report a series of five case examples that signify the role of ECT in atypical psychotic presentations, particularly when the symptoms resemble those found in Cotard's syndrome and cycloid psychosis.

The association between congenital pseudoarthrosis and osteofibrous dysplasia of the tibia and fibula is a rare entity that has been recently recognized. We report a male newborn who was found to have swelling and deformity of the left lower leg. Radiographs and magnetic resonance imaging showed an extensive destructive lesion of the tibial shaft, with dysplastic congenital pseudoarthrosis of the lower fibula. Histopathologial examination confirmed the diagnosis of congenital pseudoarthrosis of the tibia and fibula with underlying osteofibrous dysplasia involving both bones. Immunohistochemical stains showed cytokeratin positivity. (orig.)

Full Text Available Aim. To study the immunohistochemical expression of matrix metalloproteinase and tissue inhibitors of matrix metalloproteinase-2 in different histological grades of tobacco associated epithelial dysplasia and correlate the association between these proteases. Potentially malignant oral disorders (PMODs progressing to oral cancer are related to the severity of epithelial dysplasia. Methods. A retrospective immunohistochemical study was carried out on 30 clinically and histologically proven cases of leukoplakia with dysplasia and 10 cases of normal buccal mucosa using anti-MMP-2 and anti-TIMP-2 monoclonal antibodies. Results. Mann Whitney U test, for comparing the expression of both MMP-2 and TIMP-2 in normal mucosa with dysplasia, was highly significant (P<0.001. Kruskal-Wallis test to compare the median score of MMP-2 and TIMP-2 in different grades of dysplasia showed statistical significance (P<0.001, and a Spearman’s correlation between MMP-2 and TIMP-2 through different grades of dysplasia and cells observed showed positive correlation. Conclusion. Concomitant increase in the expression of both MMP-2 and TIMP-2 suggested that the activation of MMP-2 is dependent on TIMP-2 acting as a cofactor. Changes in TIMP-2 levels are considered important because they directly affect the level of MMP-2 activity.

In human cancers, podoplanin expression and its correlation with tumour invasive potential raise its possible role as a diagnostic and prognostic marker for cancer. To investigate the immunohistochemical expression of podoplanin in laryngeal Squamous Cell Carcinoma (SCC) and dysplasia. This study included a total of 60 archived, formalin fixed, paraffin embedded tissue blocks of 40 cases of laryngeal SCC and 20 cases of dysplastic lesions. The samples were immunohistochemically analysed for podoplanin expression. Podoplanin expression was significantly higher in laryngeal SCC (90%) than laryngeal dysplastic lesions (55%) (p-value=0.002). The expression of podoplanin was significantly increased with the higher grades of dysplasia (p-value=0.016). A significant positive correlation was detected between podoplanin expression in laryngeal SCC and depth of tumour invasion (p-value=0.035), and stage (p-value=0.026). The high expression of podoplanin in laryngeal SCC and its significant correlation with poor prognostic parameters recommends podoplanin as a prognostic marker in laryngeal SCC. In addition, increased podoplanin expression with higher grades of dysplasia, supports its role in malignant transformation and allows us to recommend its evaluation in premalignant lesions.

To show the different forms of radiological presentations of aspergilloma, emphasizing the importance of recognizing the atypical forms. The explorations of 11 patients with aspergilloma were examined retrospectively between 1993 and 1997. These patients were studied using conventional X-rays and computed tomography (CT): Typical and atypical radiological findings were observed. In two patients, who presented recurrent hemoptysis, a percutaneous installation of amphotericin B was carried out with tomographic control. Out of the 11 patients, two were female and nine male. In eight of the cases the radiological findings showed an intercavity injury with different evolutionary forms, while in three of the cases there was a progressive pleural swelling. In the two patients treated pertinaciously, no significant radiological changes were observed, however, neither of them showed hemoptysis again. The pleural swelling adjacent to the cavity and/or the swelling of the cavity wall are atypical radiological presentations of the aspergilloma, that can accompany or precede the appearance of this illness.

Eda Kepenekli-Kadayifci

2014-01-01

Full Text Available Mondini dysplasia, also known as Mondini malformation, is a developmental abnormality of the inner and middle ears that can cause hearing loss, cerebrospinal fluid (CSF leakage, and recurrent bacterial meningitis (RBM, which is defined as two or more episodes of meningitis separated by a period of convalescence and the complete resolution of all signs and symptoms. An accurate diagnosis of the underlying pathology is crucial to prevent further episodes from occurring. Herein, we present a three-year-old boy with RBM and unilateral sensorineural hearing loss. During the evaluation to determine the etiology of the RBM, cystic malformation in the cochlea and vestibular dilatation consistent with Mondini dysplasia were detected via computerized tomography (CT of the temporal bone.

This study aims to assess the clinical utility of a rapid fiber-optic Raman spectroscopy technique developed for enhancing in vivo diagnosis of gastric precancer during endoscopic examination. We have developed a real-time fiber-optic Raman spectroscopy system capable of simultaneously acquiring both fingerprint (FP) (i.e., 800-1800 cm(-1)) and high-wavenumber (HW) (i.e., 2800-3600 cm(-1)) Raman spectra from gastric tissue in vivo at endoscopy. A total of 5792 high-quality in vivo FP/HW Raman spectra (normal (n = 5160); dysplasia (n = 155), and adenocarcinoma (n = 477)) were acquired in real-time from 441 tissue sites (normal (n = 396); dysplasia (n = 11), and adenocarcinoma (n = 34)) of 191 gastric patients (normal (n = 172); dysplasia (n = 6), and adenocarcinoma (n = 13)) undergoing routine endoscopic examinations. Partial least squares discriminant analysis (PLS-DA) together with leave-one-patient-out cross validation (LOPCV) were implemented to develop robust spectral diagnostic models. The FP/HW Raman spectra differ significantly between normal, dysplasia and adenocarcinoma of the stomach, which can be attributed to changes in proteins, lipids, nucleic acids, and the bound water content. PLS-DA and LOPCV show that the fiber-optic FP/HW Raman spectroscopy provides diagnostic sensitivities of 96.0%, 81.8% and 88.2%, and specificities of 86.7%, 95.3% and 95.6%, respectively, for the classification of normal, dysplastic and cancerous gastric tissue, superior to either the FP or HW Raman techniques alone. Further dichotomous PLS-DA analysis yields a sensitivity of 90.9% (10/11) and specificity of 95.9% (380/396) for the detection of gastric dysplasia using FP/HW Raman spectroscopy, substantiating its clinical advantages over white light reflectance endoscopy (sensitivity: 90.9% (10/11), and specificity: 51.0% (202/396)). This work demonstrates that the fiber-optic FP/HW Raman spectroscopy technique has great promise for enhancing in vivo diagnosis of gastric

Full Text Available Abstract Introduction Ectrodactyly-ectodermal dysplasia-cleft lip or palate syndrome (OMIM No. 129900 is characterized by the triad of ectrodactyly, ectodermal dysplasia and facial clefting (of the lip and/or palate. Holoprosencephaly denotes a failure in the division of the embryonic forebrain (prosencephalon into distinct lateral cerebral hemisphere. The association between ectrodactyly-ectodermal dysplasia-cleft lip or palate syndrome and holoprosencephaly is very rare. Here we report holoprosencephaly in an Egyptian infant with ectrodactyly-ectodermal dysplasia-cleft lip or palate syndrome. Case presentation An 11-month-old Egyptian female baby was referred to our institution for an evaluation of poor growth; the pregnancy and perinatal history were uneventful. On examination, her growth parameters were below the third centile, she had bilateral ectrodactyly of both hands and feet, dry rough skin, sparse hair of the scalp and operated right cleft lip and cleft palate. Computerized tomography of her brain revealed holoprosencephaly. Conclusion The importance of the early diagnosis of this syndrome should be emphasized in order to implement a multidisciplinary approach for proper management of such cases.

Hemimegalencephaly is a well-known congenital malformation. However, localized megalencephaly, which may be one of the subtypes of hemimegalencephaly, has not been separately investigated. In the present study, we attempted to characterize the clinical and magnetic resonance (MR) imaging features of localized megalencephaly in comparison with ordinary diffuse hemimegalencephaly and multilobar cortical dysplasia. MR findings for 43 patients with hemimegalencephaly and ten with multilobar cortical dysplasia, which is the differential diagnosis of localized megalencephaly, were retrospectively reviewed. Clinical findings such as the onset and severity of seizures and imaging findings including the affected area of the brain, structures outside of the hemisphere, and interval morphological changes were examined. Of the 43 patients, 11 showed signs of localized megalencephaly (25.6%). Localized megalencephaly was predominantly seen on the left side (72.7%) and had a tendency toward severe-grade seizures compared to multilobar cortical dysplasia. The frequencies of the extracerebral abnormalities in the diffuse hemimegalencephaly, localized megalencephaly, and multilobar cortical dysplasia groups were 84.4%, 36.4%, and 0.0%, respectively. There were three localized megalencephaly patients whose affected areas shrank and whose images were similar to those of multilobar cortical dysplasia. Localized megalencephaly accounts for one quarter of all hemimegalencephaly cases in this study. The incidence of extracerebral abnormalities in patients with localized hemimegalencephaly was almost half that of patients with diffuse hemimegalencephaly. Extracerebral abnormalities were absent in patients with multilobar cortical dysplasia. Associated extracerebral abnormalities may be a clue to differentiating localized megalencephaly from multilobar cortical dysplasia. (orig.)

Muscle-tendon-related abnormalities detected by ultrasonography are common in symptomatic hip dysplasia

Jacobsen, Julie Sandell; Bolvig, Lars; Hölmich, Per

2018-01-01

INTRODUCTION: Hip dysplasia is characterized by reduced acetabular coverage of the femoral head leading to an increased mechanical load on the hip joint and the acting hip muscles.

Ectodermal dysplasias are rare conditions with a triad of hypotrichosis, anodontia and anhidrosis. In literature review there have been only a few reports of anesthetic management of patients with ectodermal dysplasias. Hyperthermia is a very serious risk which may occur due to the defect of sweat glands. The present case involves a 10-year-old child with ectodermal dysplasia who presented with an acute abdomen and was considered for an emergency surgery. Our aim was to demonstrate the successful management of this case using a combination of general and epidural anesthesia. It is important for anesthesiologist to have information about this syndrome in case of emergency operations, since it can prevent serious complications and even save lives.

Science.gov (United States)

Yavuzer, R; Khilnani, R; Jackson, I T; Audet, B

1999-10-01

McCune-Albright syndrome (MAS) is a disease of noninheritable, genetic origin defined by the triad of café-au-lait pigmentation of the skin, precocious puberty, and polyostotic fibrous dysplasia. This syndrome, which affects young girls primarily, has also been reported with other endocrinopathies, and rarely with acromegaly and hyperprolactinemia. The fibrous dysplasia in MAS is of the polyostotic type and, apart from the characteristic sites such as the proximal aspects of the femur and the pelvis, the craniofacial region is frequently involved. A male patient with MAS presented with juvenile gigantism, precocious puberty, pituitary adenoma-secreting growth hormone and prolactin, hypothalamic pituitary gonadal and thyroid dysfunction, and polyostotic fibrous dysplasia causing optic nerve compression. Visual deterioration and its surgical management are presented.

Fibrous dysplasia and cherubism

Directory of Open Access Journals (Sweden)

Surajit Bhattacharya

2015-01-01

Full Text Available Fibrous dysplasia (FD is a non-malignant fibro-osseous bony lesion in which the involved bone/bones gradually get converted into expanding cystic and fibrous tissue. The underlying defect in FD is post-natal mutation of GNAS1 gene, which leads to the proliferation and activation of undifferentiated mesenchymal cells arresting the bone development in woven phase and ultimately converting them into fibro-osseous cystic tissue. Cherubism is a hereditary form of fibrous dysplasia in which the causative factor is transmission of autosomal dominant SH3BP2 gene mutation. The disease may present in two distinct forms, a less severe and limited monostotic form, and a more aggressive and more widespread polyostotic form. Polyostotic form may be associated with various endocrine abnormalities, which require active management apart from the management of FD. Management of FD is not free from controversies. While total surgical excision of the involved area and reconstruction using newer micro-vascular technique is the only definitive treatment available from the curative point of view, but this can be only offered to monostotic and very few polyostotic lesions. In polyostotic varieties on many occasions these radical surgeries are very deforming in these slow growing lesions and so their indication is highly debated. The treatment of cranio-facial fibrous dysplasia should be highly individualized, depending on the fact that the clinical behavior of lesion is variable at various ages and in individual patients. A more conservative approach in the form of aesthetic recontouring of deformed bone, orthodontic occlusal correction, and watchful expectancy may be the more accepted form of treatment in young patients. Newer generation real-time imaging guidance during recontouring surgery adds to accuracy and safety of these procedures. Regular clinical and radiological follow up is required to watch for quiescence, regression or reactivation of the disease process

Central ossifying fibroma, periapical cemento-osseous dysplasia and complex odon-toma occurring in the same jaw.

2011-05-16

Central ossifying fibroma is a rare, benign fibro-osseous lesion that arises from the periodontal ligament. Periapical cemento-osseous dysplasia is another variant of fibro-osseous lesion which occurs in the anterior region of the mandible of females. Odontoma is a benign odontogenic tumor that contains enamel, dentine cement and pulp tissue. A 46-year-old woman was referred to the Department of Oral Medicine, School of Dentistry, Tehran University of Medical Sciences, with two non-painful swellings on both sides of the mandible, which had been slowly growing over a period of one year. Our differential diagnosis was florid cemento-osseous dysplasia, focal cemento-osseous dysplasia for the right side, complex odontoma for the left side and periapical cement-osseous dysplasia for the anterior side. The historical feature revealed ossifying fibroma, complex odontoma and periapical cemento-osseous dysplasia. The occurrence of these three lesions in the same jaw has been rarely reported in the literature. The relationship between the occurrence of these three lesions is not obvious it could be coincidental. It seems that more case reports are needed to establish the relationship between them.

Full Text Available Abstract Background Atypical antipsychotics are increasingly used for treatment of mental illnesses like schizophrenia and bipolar disorder, and considered to have fewer extrapyramidal effects than older antipsychotics. Methods We examined efficacy in randomised trials of bipolar disorder where the presenting episode was either depression, or manic/mixed, comparing atypical antipsychotic with placebo or active comparator, examined withdrawals for any cause, or due to lack of efficacy or adverse events, and combined all phases for adverse event analysis. Studies were found through systematic search (PubMed, EMBASE, Cochrane Library, and data combined for analysis where there was clinical homogeneity, with especial reference to trial duration. Results In five trials (2,206 patients participants presented with a depressive episode, and in 25 trials (6,174 patients the presenting episode was manic or mixed. In 8-week studies presenting with depression, quetiapine and olanzapine produced significantly better rates of response and symptomatic remission than placebo, with NNTs of 5–6, but more adverse event withdrawals (NNH 12. With mania or mixed presentation atypical antipsychotics produced significantly better rates of response and symptomatic remission than placebo, with NNTs of about 5 up to six weeks, and 4 at 6–12 weeks, but more adverse event withdrawals (NNH of about 22 in studies of 6–12 weeks. In comparisons with established treatments, atypical antipsychotics had similar efficacy, but significantly fewer adverse event withdrawals (NNT to prevent one withdrawal about 10. In maintenance trials atypical antipsychotics had significantly fewer relapses to depression or mania than placebo or active comparator. In placebo-controlled trials, atypical antipsychotics were associated with higher rates of weight gain of ≥7% (mainly olanzapine trials, somnolence, and extrapyramidal symptoms. In active controlled trials, atypical antipsychotics

The chest radiographs of 95 patients with the new diagnosis of atypical turberculosis were reviewed to determine if any significant differences between atypical tuberculosis and that caused by Mycobacterium tuberculosis could be discerned. Findings included upper lobe involvement in B4 of the 95 patients and cavities in 76, with nearly equal groups having no, moderate, or extensive surrounding alveolar disease. Nodules were common; in six patients a nodule was the sole manifestation of disease. Adenopathy was seen in 12 of the 95 patients, atlectasis in 45, pleural thickening in 90, and effusions in three. These radiographic findings did not allow the radiographic differentiation of atypical tuberculosis from Mycobacterium tuberculosis infection

Florid cemento-osseous dysplasia (FCOD) is commonly seen in black women, but few cases have been reported in sub-Saharan Africa. This article presents two cases of FCOD seen at the University College Hospital Ibadan. Two women aged 70 and 60 years were initially diagnosed as chronic osteomyelitis but both were eventually diagnosed as florid cementoosseous dysplasia after radiological examination by orthopanthomogram. Diagnosis of florid cemento-osseous dysplasia is possible by clinical examination and the distinct radiological presentation, especially on orthopanthomogram and a biopsy may not be required.

To study the immunohistochemical expression of matrix metalloproteinase and tissue inhibitors of matrix metalloproteinase-2 in different histological grades of tobacco associated epithelial dysplasia and correlate the association between these proteases. Potentially malignant oral disorders (PMODs) progressing to oral cancer are related to the severity of epithelial dysplasia. A retrospective immunohistochemical study was carried out on 30 clinically and histologically proven cases of leukoplakia with dysplasia and 10 cases of normal buccal mucosa using anti-MMP-2 and anti-TIMP-2 monoclonal antibodies. Mann Whitney U test, for comparing the expression of both MMP-2 and TIMP-2 in normal mucosa with dysplasia, was highly significant (P correlation between MMP-2 and TIMP-2 through different grades of dysplasia and cells observed showed positive correlation. Concomitant increase in the expression of both MMP-2 and TIMP-2 suggested that the activation of MMP-2 is dependent on TIMP-2 acting as a cofactor. Changes in TIMP-2 levels are considered important because they directly affect the level of MMP-2 activity.

Ectrodactyly ectodermal dysplasia-cleft syndrome is a rare genetic syndrome with an incidence of 1/90,000 live births, characterized by cleft lip and palate, severely hypoplastic maxilla, and hypodontia. Patients diagnosed with ectrodactyly ectodermal dysplasia-cleft syndrome suffer from a severely hypoplastic maxilla that is highly difficult to treat using traditional orthognathic methods. In this study, we propose using distraction osteogenesis to achieve a major advancement while maintaining good stability and minimal relapse. To our knowledge, this is the first description of patients with this syndrome treated using distraction osteogenesis. Five patients diagnosed with ectrodactyly ectodermal dysplasia-cleft syndrome were included in the study. All patients had been operated on according to the well-established protocol of cleft lip and palate reconstruction before maxillary distraction osteogenesis. Hard and soft-tissue changes were evaluated by cone beam computed tomography and lateral cephalograms before distraction osteogenesis (T1), at the postdistraction point (T2) and after 1 year of follow-up (T3). Examination revealed marked maxillary advancement in all our patients with a significant mean difference in hard tissue parameters (condylion to A point = 18 mm; nasion-sella line to A point = 15.2 degrees) and a notable improvement in facial convexity (20.9 degrees). One year follow-up measurements demonstrated mild relapse rates of 6% in the horizontal plane. We conclude that despite the challenging anatomic and physiological features of ectrodactyly ectodermal dysplasia-cleft patients, by enhancing current surgical techniques, there is promising potential for improved patient outcomes, achieving normognathic facial appearance with implant supported rehabilitation.

Cerebral infarction attributable to cerebrovascular fibromuscular dysplasia

International Nuclear Information System (INIS)

Shimazaki, Haruo

2008-01-01

Fibromuscular dysplasia (FMD) is a noninflammatory, nonatheromatous segmental angiopathy. The renal arteries are affected most commonly, followed by the internal carotid and vertebral arteries. FMD of the internal carotid and vertebral arteries usually occurs in the extracranial portions and is mostly observed at the level of the second cervical vertebra. FMD of the intracranial arteries is rare, but tends to occur in children and young adults. FMD is more common in females than in males, and it is often observed in middle-aged women. Although the etiology of FMD is not well understood, several mechanisms have been proposed, such as genetic predisposition, hormonal factors, and arterial wall ischemia. The pathology of FMD is characterized by smooth muscle hyperplasia or thinning, elastic fiber destruction, fibrous tissue proliferation, and arterial wall disorganization. Cerebrovascular fibromuscular dysplasia (cFMD) is relatively rare in Japan but is regarded as one of the cardinal causes of stroke in the younger population. cFMD without complications causes nonspecific symptoms such as headache or vertigo, but when it results in an arterial dissection or aneurysm, it leads to cerebral infarction or subarachnoid hemorrhage. Conventional angiographic findings mostly reveal a pattern called the 'string of beads', which is pathologically correlated to medial fibromuscular dysplasia. Doppler echography, computed tomography and magnetic resonance angiography (MRA) may be useful for detecting cFMD lesions in some cases. MRA should be performed to rule out the presence of intracranial aneurysms. Antiplatelet and anticoagulation agents are prophylactics against cFMD complications. Surgical treatments such as graduated intraluminal dilatation had previously been the mainstays for treating cFMD. Percutaneous transluminal angioplasty with or without stenting has now become the preferred invasive treatment for symptomatic cFMD. (author)

We report a 35-year-old mulatto female patient with neurofibromatosis Type 1 who presented with facial asymmetry. The patient had two lesions: florid cemento-osseous dysplasia associated with peripheral giant cell granuloma. She was referred for surgical treatment of the peripheral giant cell granuloma and the florid cemento-osseous dysplasia was treated conservatively by a multidisciplinary team. So far, no changes have been observed in the patient's clinical status. We observed no recurrence of peripheral giant cell granuloma. To the best of our knowledge, the present case is the first report of a patient with neurofibromatosis Type 1 associated with a giant cell lesion and florid cemento-osseous dysplasia.

We report ocular findings from 2 children with Kniest dysplasia. Both eyes of the 2 patients had abnormal long axial length causing high myopia, and vitreoretinal degeneration. The vitreous cavity of case 1 (a 15-year-old boy) which contained fibrous clouded membranous structures floating in the retrolental space and dense opacity at the temporal-inferior portion, was optically empty. Case 2 (a 7-year-old boy) had cortical and posterior subcapsular opacity of the lens, and also veil-like vitreous opacity in the periphery. Their common retinal changes were characterized as perivascular lattice degeneration and white without pressure in various degrees. They have not yet shown cataract or retinal detachment which needs surgical treatment, but close ophthalmological follow up will be necessary for their favorable prognosis. The literature on vitreoretinal degeneration such as Wagner's disease or Stickler syndrome may indicate the relation of Kniest dysplasia to similar diseases. Because they might have different clinical courses and visual prognosis according to the original biosynthetic disorders, we emphasized the importance of orthopedic diagnosis regarding such vitreoretinal degeneration with constitutional bone diseases.

Ichthyosiform mycosis fungoides with alopecia and atypical membranous nephropathy

2011-01-01

Full Text Available We describe here a rare case of variant of mycosis fungoides (MF: ichthyosiform MF with alopecia and atypical membranous nephropathy. The diagnosis was made based on the following findings: generalized ichthyosis-like eruption, alopecia, enlarged superficial lymph nodes, proteinuria, and hematuria, the histological features of the skin biopsy from both ichthyotic and alopecic lesions with immunohistochemical staining, and the renal biopsy examination with immunofluorescence. The histological examination of ichthyotic and alopecic lesions displayed a predominant infiltration of atypical lymphocytes in the upper dermis with the characteristics of epidermotropism and folliculotropism. Immunohistochemical studies demonstrated that most infiltrated atypical lymphocytes were CD3, CD4, and CD45RO positive, whereas negative for CD5, CD7, CD20, CD30, and CD56. A renal biopsy examination revealed atypical membranous nephropathy with deposition of immunoglobulin G (IgG, IgM, IgA, C1q, and C3. In this case atypical membranous nephropathy was involved, which is very uncommon and has never been presented in the literature to date. Although ichthyosiform MF usually features a relatively favorable course, diffuse alopecia and the renal involvement in this case might indicate aggressive disease and poor prognosis.

Centrioles are conserved, self-replicating, microtubule-based, 9-fold symmetric subcellular organelles that are essential for proper cell division and function. Most cells have two centrioles and maintaining this number of centrioles is important for animal development and physiology. However, how animals gain their first two centrioles during reproduction is only partially understood. It is well established that in most animals, the centrioles are contributed to the zygote by the sperm. However, in humans and many animals, the sperm centrioles are modified in their structure and protein composition, or they appear to be missing altogether. In these animals, the origin of the first centrioles is not clear. Here, we review various hypotheses on how centrioles are gained during reproduction and describe specialized functions of the zygotic centrioles. In particular, we discuss a new and atypical centriole found in sperm and zygote, called the proximal centriole-like structure (PCL). We also discuss another type of atypical centriole, the "zombie" centriole, which is degenerated but functional. Together, the presence of centrioles, PCL, and zombie centrioles suggests a universal mechanism of centriole inheritance among animals and new causes of infertility. Since the atypical centrioles of sperm and zygote share similar functions with typical centrioles in somatic cells, they can provide unmatched insight into centriole biology.

Hip dysplasia is characterized by an excessively oblique and shallow acetabulum with insufficient coverage of the femoral head. It is a known cause of pain and the development of early osteoarthritis in young adults. The periacetabular osteotomy is the joint-preserving treatment of choice in young...... adults with symptomatic hip dysplasia. The surgical aim of this extensive procedure is to reorient the acetabulum to improve coverage and eliminate the pathological hip joint mechanics. Intraoperative assessment of the achieved acetabular reorientation is therefore crucial. The "classic" surgical...

Mondini dysplasia is a congenital malformation of the inner ear, commonly associated with hearing impairment, cerebrospinal fluid otorrhea/rhinorrhea and recurrent meningitis. Two such cases are described, with hearing impairment, cerebrospinal fluid rhinorrhea, and several episodes of meningitis. Diagnosis was confirmed by high-resolution computed tomography. After surgical correction of the malformation, there was no recurrent episode of meningitis at subsequent follow-up. To avoid the suffering and the sequelae of recurrent meningitis, an early diagnosis and prompt surgical intervention are crucial for such patients.

The use of cochlear implantation to treat patients with inner ear malformations such as Mondini dysplasia has been increasingly successful. Until now, conventional hearing aids in these patients have not performed well. Consequently, the hearing problem for patients with this condition has been somewhat improved with the use of cochlear implants. Various results of cochlear implantation have been reported in these patients so far. This is a report of 5 patients with Mondini malformation who have undergone cochlear implant surgery.

Cerebrospinal fluid otorrhea and pseudomonal meningitis in a child with Mondini dysplasia: case report.

Science.gov (United States)

Hernandez, R Nick; Changa, Abhinav R; Bassani, Luigi; Jyung, Robert W; Liu, James K

2015-09-01

Mondini dysplasia is a rare congenital inner ear malformation that presents with abnormal cochlear development with accompanied vestibular dilation and vestibular aqueduct enlargement. This dysfunctional anatomy provides the potential for sensorineural hearing deficits, cerebrospinal fluid leaks, and severe cases of recurrent meningitis. We present the case of a child with Mondini dysplasia who presented with unilateral hearing loss and cerebrospinal fluid (CSF) otorrhea that was surgically repaired through a combined middle fossa/transmeatal middle ear approach to alleviate any recurrence of infection and cerebrospinal fluid otorrhea. Postoperatively, the patient remained neurologically stable without any further CSF leakage. CSF cultures revealed a Pseudomonas aeruginosa infection, a rare occurrence within the context of Mondini dysplasia. Retrograde bacterial spread from the external ear canal into the CSF space has been theorized as the possible pathogenesis of the resulting meningitis. The patient was successfully treated with intravenous antibiotics without any neurologic complications. Although Mondini dysplasia is a rare malformation, the life-threatening sequelae of meningitis that can result from the dysfunctional anatomy makes it a condition that requires elevated clinical vigilance, especially when considering children with hearing loss associated with recurrent meningitis, otorrhea, or rhinorrhea.

The common clinical features include facial dysmorphism with thin nose, microphthalmia, syndactyly, tooth anomalies such as enamel hypoplasia, anodontia, microdontia, early tooth loss and conductive deafness. Other less common features are abnormalities of the skin and its appendages, such as brittle nails, sparse hair, and neurological abnormalities. To prevent this syndrome from being overlooked, awareness of possible symptoms is necessary. Early recognition can prevent blindness, dental problems and learning disabilities. Described here is the case of a 21-year-old male who presented to the ophthalmology outpatient department with a complaint of bilateral progressive loss of vision since childhood.

Identification of patients with oral dysplasia at high risk of cancer development and oral squamous cell carcinoma (OSCC) at increased risk of disease recurrence will enable rigorous personalized treatment. Regulated intramembranous proteolysis of Epithelial cell adhesion molecule (EpCAM) resulting in release of its intracellular domain Ep-ICD into cytoplasm and nucleus triggers oncogenic signaling. We analyzed the expression of Ep-ICD in oral dysplasia and cancer and determined its clinical significance in disease progression and prognosis. In a retrospective study, immunohistochemical analysis of nuclear and cytoplasmic Ep-ICD and EpEx (extracellular domain of EpCAM), was carried out in 115 OSCC, 97 oral dysplasia and 105 normal oral tissues, correlated with clinicopathological parameters and disease outcome over 60 months for oral dysplasia and OSCC patients. Disease-free survival (DFS) was determined by Kaplan-Meier method and multivariate Cox regression analysis. In comparison with normal oral tissues, significant increase in nuclear Ep-ICD and membrane EpEx was observed in dysplasia, and OSCC (p = 0.013 and < 0.001 respectively). Oral dysplasia patients with increased overall Ep-ICD developed cancer in short time period (mean = 47 months; p = 0.044). OSCC patients with increased nuclear Ep-ICD and membrane EpEx had significantly reduced mean DFS of 33.7 months (p = 0.018). Our study provided clinical evidence for Ep-ICD as a predictor of cancer development in patients with oral dysplasia and recurrence in OSCC patients, suggesting its potential utility in enhanced management of those patients detected to have increased risk of progression to cancer and recurrence in OSCC patients

The purpose of the study was to investigate the etiological factors and the audiological data of different types of inner ear malformations, which the authors thought might be helpful in elucidating the inter-relation among malformations and shedding light on pathogenesis. Retrospective study from 1998 to 2002 at a tertiary care university hospital. One hundred sixty consecutive children with a total of 302 affected ears undergoing high-resolution computed tomography of the temporal bone for sensorineural hearing loss were enrolled. The image results were correlated with causes and origins, hearing loss patterns, hearing levels, and audiogram configurations. Inner ear malformation was present in 114 (38%) ears. The most common malformations were enlarged vestibular aqueduct, incomplete partition of cochlea (Mondini dysplasia), large vestibule, and semicircular canal dysplasia, presenting either as isolated finding or in combination. Eighty-four (74%) ears had abnormalities confined to these four malformations; only 30 (26%) ears showed other malformations. Patients with complex of enlarged vestibular aqueduct, Mondini dysplasia, large vestibule, and semicircular canal dysplasia (EMVS complex) demonstrated a significantly higher incidence of fluctuating hearing loss (93%) and a better hearing level compared with those with other malformations. Homogeneity in audiological features among these four malformations was also disclosed. The authors identified a distinct clinical entity, the EMVS complex, which is characterized by fluctuating hearing loss and a better hearing level. The authors proposed that malformations belonging to this complex result from a common pathogenetic mechanism.

We report a case of bilateral temporal bone anomalies in a child with symptomatic congenital cytomegalovirus infection and severe, bilateral sensorineural hearing loss identified at 3 months of age. High-resolution temporal bone computed tomography (HRCT) revealed bilateral findings of a short, malformed cochlea lacking an interscalar septum, a short and wide internal auditory canal, and an enlarged vestibular aqueduct, features diagnostic of bilateral Mondini dysplasia. To determine the importance of this observation, we completed HRCT in five additional children between 7 months and 9 years of age who had evidence of symptomatic congenital cytomegalovirus infection. One child with profound sensorineural hearing loss had severe bilateral temporal bone dysplasia with a small cochlea lacking an interscalar septum, an abnormal vestibule, and a large cochlear aqueduct. Of the remaining four children, hearing thresholds ranged from normal to profoundly decreased, but their HRCT scans were normal to visual inspection. When inner ear dimensions of these temporal bones were compared with norms established by Pappas and coworkers, however, seven of the eight ears had short cochleas and narrow lateral semicircular canals, and three ears had short or narrow vestibules. These results indicate that congenital cytomegalovirus infection may cause anomalies or growth disturbances of the temporal bone.

Adolescents with atypical anorexia nervosa (AN) have lost significant weight but are not underweight. This study aimed to describe the physical and psychological morbidity of adolescents diagnosed with atypical AN, and to compare them with underweight adolescents with AN. All first presentations of atypical AN (n = 42) and full-threshold AN (n = 118) to a specialist pediatric eating disorder program between July 2010 and June 2014 were examined. Diagnosis was assessed by using the Eating Disorder Examination and anthropometric measurement. Psychological morbidity measures included eating and weight concerns, bingeing, purging, compulsive exercise, and psychiatric comorbidity. Compared with AN, more adolescents with atypical AN were premorbidly overweight or obese (71% vs 12%). They had lost more weight (17.6 kg vs 11.0 kg) over a longer period (13.3 vs 10.2 months). There was no significant difference in the frequency of bradycardia (24% vs 33%;) or orthostatic instability (43% vs 38%). We found no evidence of a difference in frequency of psychiatric comorbidities (38% vs 45%) or suicidal ideation (43% vs 39%). Distress related to eating and body image was more severe in atypical AN. Atypical AN considerably affects physical and psychological functioning, despite adolescents presenting within or above the normal weight range. There was little evidence that the morbidity of adolescents with atypical AN was any less severe than that of adolescents with full-threshold AN. The findings support the need for vigilance around weight loss in adolescents, regardless of body size. Copyright © 2016 by the American Academy of Pediatrics.

The diagnosis of skeletal dysplasias: a multidisciplinary approach

International Nuclear Information System (INIS)

Mortier, Geert R.

2001-01-01

Skeletal dysplasias are heritable connective tissue disorders affecting skeletal morphogenesis and development. They represent a heterogeneous group of genetic disorders with more than 200 different entities being delineated to date. Because of this diversity, the diagnosis of a skeletal dysplasia is usually based on a combination of clinical, radiographic, morphologic, and, in some instances, biochemical and molecular studies. Tremendous advances have been made in the elucidation of the genetic defect of several of these conditions over the past 10 years. This progress has provided us with more insights into the genes controlling normal skeletal development. It also has opened new diagnostic perspectives. For several disorders, identification of the causal gene allows us now to confirm with a molecular test the diagnosis postulated on the basis of clinical, radiographic and/or morphologic studies. It also enables us to establish the diagnosis early in pregnancy. An accurate diagnosis is not only important for proper management of the affected individual but also the cornerstone for adequate genetic counseling

Full Text Available Ectodermal dysplasia is described as heritable conditions that involve anomalies of structures derived from the ectoderm, including hypodontia. In the cases of edentulous young patients, who did not finish their craniofacial growth, treatment with conventional complete denture is a suitable alternative. The aim of this study was to report a case of mandibular edentulism treated with conventional complete denture in a thirteen-year-old patient diagnosed with hidrotic ectodermal dysplasia. Typical features, such as frontal bossing, depressed nasal bridge, protuberant lips, scarce hair, and brittle nails, were visualized during the extraoral examination. The intraoral inspection and radiographic analysis revealed oligodontia, dental malformation, and prolonged retention of deciduous teeth at maxilla and total edentulism at mandible. A conventional complete denture was planned and constructed following the same steps of technique as recommended in adults. Although this option is not a definitive treatment, the patient and his parents were satisfied with his improvement in chewing and speech, as well as with the aesthetic benefits.

Osteosclerotic metaphyseal dysplasia: a skeletal dysplasia that may mimic lead poisoning in a child with hypotonia and seizures

Mennel, Emilie A.; John, Susan D.

2003-01-01

We report the case of a 23-month-old male with hypotonia, developmental delay, and complex seizures. Radiographs revealed profound sclerosis of the metaphyses and epiphyses of the long and short bones in the extremities, with a unique pattern of distribution. Sclerosis also involved the anterior ribs, iliac crests, talus, and calcaneus. The skull and vertebral bodies appeared unaffected. Blood lead levels were normal. We believe that this constellation of clinical and radiographic abnormalities closely resembles osteosclerotic metaphyseal dysplasia (OMD) due to an autosomal recessive defect. Characteristic skeletal findings were instrumental in determining the diagnosis. OMD is a very rare sclerosing bone disorder, first described in 1993. The syndrome is characterized clinically by developmental delay of a progressive nature, hypotonia, elevated alkaline phosphatase, and late-onset spastic paraplegia. We encountered a young child with these neurologic symptoms who displayed sclerotic metaphyseal changes on hand radiographs obtained to determine the bone age. Lead poisoning, a known cause of metaphyseal sclerosis, was initially suspected. Careful analysis of the metaphyseal bone changes helped to distinguish this bone dysplasia from lead poisoning and other causes of metaphyseal sclerosis. (orig.)

Full Text Available Multiple epiphyseal dysplasia (MED is a congenital disorder of skeletal development that primarily affects the ends of long bones, causing progressive joint and bone inflammation and short stature. Mutations in several genes are responsible for pathogenesis of this disease. We are reporting a case of MED who presented with the complaints of multiple swelling of the joints which was associated with pain during movement for last seven years. The patient had flexion deformity of all the affected joints along with restriction of movement. These were associated with kyphosis, pectus carnitum, knock-knee and short stature. Radiological findings were suggestive of MED. Counseling was done with the parents regarding the etiology, progression and outcome of the disease.DOI: http://dx.doi.org/10.3329/bsmmuj.v5i1.11025 BSMMU J 2012; 5(1:57-60

We report a 35-year-old mulatto female patient with neurofibromatosis Type 1 who presented with facial asymmetry. The patient had two lesions: florid cemento-osseous dysplasia associated with peripheral giant cell granuloma. She was referred for surgical treatment of the peripheral giant cell granuloma and the florid cemento-osseous dysplasia was treated conservatively by a multidisciplinary team. So far, no changes have been observed in the patient's clinical status. We observed no recurrence of peripheral giant cell granuloma. To the best of our knowledge, the present case is the first report of a patient with neurofibromatosis Type 1 associated with a giant cell lesion and florid cemento-osseous dysplasia. PMID:28538890

Bilateral anophthalmia is a rare entity and association with septo-optic dysplasia is an even rare condition. The condition is characterized by absent eyeballs in the presence of eyelids, conjunctiva or lacrimal apparatus. Though anophthalmia can be diagnosed clinically, imaging plays a crucial role in delineating the associated anomalies. In addition, often clinical anophthalmia may prove to be severe microphthalmia on imaging. We describe the imaging findings in an infant with bilateral ano...

Science.gov (United States)

Rachmiel, Adi; Emodi, Omri; Aizenbud, Dror; Shilo, Dekel

2018-01-01

Background: Ectrodactyly ectodermal dysplasia-cleft syndrome is a rare genetic syndrome with an incidence of 1/90,000 live births, characterized by cleft lip and palate, severely hypoplastic maxilla, and hypodontia. Patients diagnosed with ectrodactyly ectodermal dysplasia-cleft syndrome suffer from a severely hypoplastic maxilla that is highly difficult to treat using traditional orthognathic methods. In this study, we propose using distraction osteogenesis to achieve a major advancement while maintaining good stability and minimal relapse. To our knowledge, this is the first description of patients with this syndrome treated using distraction osteogenesis. Methods: Five patients diagnosed with ectrodactyly ectodermal dysplasia-cleft syndrome were included in the study. All patients had been operated on according to the well-established protocol of cleft lip and palate reconstruction before maxillary distraction osteogenesis. Hard and soft-tissue changes were evaluated by cone beam computed tomography and lateral cephalograms before distraction osteogenesis (T1), at the postdistraction point (T2) and after 1 year of follow-up (T3). Results: Examination revealed marked maxillary advancement in all our patients with a significant mean difference in hard tissue parameters (condylion to A point = 18 mm; nasion-sella line to A point = 15.2 degrees) and a notable improvement in facial convexity (20.9 degrees). One year follow-up measurements demonstrated mild relapse rates of 6% in the horizontal plane. Conclusions: We conclude that despite the challenging anatomic and physiological features of ectrodactyly ectodermal dysplasia-cleft patients, by enhancing current surgical techniques, there is promising potential for improved patient outcomes, achieving normognathic facial appearance with implant supported rehabilitation.

Diagnostic and surgical management of severe chronic angle- closure glaucoma secondary to ciliary body cysts can be difficult to manage in a patient with oculodentodigital dysplasia. A 6-year old girl with oculodentodigital dysplasia, with progressive chronic angle- closure glaucoma secondary to ciliary body cysts presented to our clinic. The initial examination revealed counting fingers vision in the left eye. Intraocular pressure (IOP), as assessed by tonopen, was 31 mm Hg. Ultrasound biomicroscopy revealed ciliary body cysts in the left eye, and gonioscopy confirmed chronic angle closure. A tube shunt was placed to control the elevated IOP. A year after her tube shunt placement in the left eye, ultrasound biomiscropy was performed on her right eye and showed no ciliary body cysts. Gonioscopy in the right eye revealed an open angle to the ciliary body band. Subsequent serial gonioscopy every 3 months showed gradual narrowing of the right eye angle and finally three-and-a-half years after tube placement of the left eye, her right eye IOP became uncontrolled with medications alone and a tube shunt was similarly placed in the right eye. Intraoperative ultrasound biomicroscopy performed at the time of the right eye tube shunt revealed extensive ciliary body cysts in the right eye. Her IOP in both eyes have been well controlled since the placement of tube shunts. This is one of the first reported cases of severe chronic angle- closure glaucoma secondary to ciliary body cysts in a patient with oculodentodigital dysplasia. We believe that early screening for ciliary body cysts is important in patients with oculodentodigital dysplasia.

Diastrophic dysplasia: prenatal diagnosis and review of the literature

Directory of Open Access Journals (Sweden)

Jonathan Celli Honório

Full Text Available CONTEXT Diastrophic dysplasia is a type of osteochondrodysplasia caused by homozygous mutation in the gene DTDST (diastrophic dysplasia sulfate transporter gene. Abnormalities occurring particularly in the skeletal and cartilaginous system are typical of the disease, which has an incidence of 1 in 100,000 live births. CASE REPORT The case of a pregnant woman, without any consanguineous relationship with her husband, whose fetus was diagnosed with skeletal dysplasia based on ultrasound findings and DNA tests, is described. An obstetric ultrasound scan produced in the 16th week of gestation revealed characteristics that guided the clinical diagnosis. Prominent among these characteristics were rhizomelia of the lower and upper limbs (shortening of the proximal portions and mesomelia (shortening of the intermediate portions. Both upper limbs showed marked curvature, with the first finger of the upper limbs in abduction and clinodactyly of the fifth finger. Molecular analysis using the polymerase chain reaction (PCR and gene sequencing detected mutations that had already been described in the literature for the gene DTDST, named c.862C > T and c.2147_2148insCT. Therefore, the fetus was a compound heterozygote, carrying two different mutations. CONCLUSIONS Prenatal diagnosis of this condition allowed a more realistic interpretation of the prognosis, and of the couple's reproductive future. This case report shows the contribution of molecular genetics towards the prenatal diagnosis, for which there are few descriptions in the literature.

De Jong, W F; Albrecht, M; Bánóczy, J; van der Waal, I

1984-06-01

In a combined study of the Free University, Amsterdam and the Semmelweis Medical University, Budapest, the presence of epithelial dysplasia was studied in 100 cases of oral lichen planus. The criteria of epithelial dysplasia which were used in this study correspond with those reported by the WHO Collaborating Centre for Oral Precancerous Lesions in 1978. In approximately 25% of all cases, moderate or at least mild dysplasia was observed. The number of dysplastic changes per section did not show any significant correlation with the clinical type, nor with age or sex. There were no marked differences between the Amsterdam and Budapest material. Long-term data on the follow-up were not available yet. No comment can therefore be given about the meaning of the finding of epithelial dysplasia in lichen planus being a sign of premalignancy or not.

Low risk HPV types 6/11 are responsible for some low-grade cytological abnormalities. Most economic analyses of HPV vaccination have estimated the additional benefit of HPV 6/11 protection by the quadrivalent vaccine, over the bivalent, based on reduction of genital warts but have not included reduction in repeat smears and colposcopies due to low-grade abnormalities. We investigate the contribution of HPV types 6/11 to abnormal smears and associated costs in England. The risk of borderline or mild dysplasia due to HPV 6/11 infection was estimated from a study of type-specific HPV DNA in cervical screening specimens collected throughout England. A Markov model representing 10 million women with HPV 6/11 or with no HPV infection from 24 to 64 years was developed to estimate the number of abnormal smears, subsequent repeat smears and colposcopies due to HPV 6/11 associated with borderline or mild dysplasia. Fitting was achieved by varying the force of infection, probability of borderline or mild dysplasia if HPV-uninfected or infected with HPV 6/11 and the duration of infection. The relative risks of borderline or mild dysplasia when infected with HPV 6/11 compared to not being HPV infected were 6.32 (95% credible interval 1.56-25.6) and 17.5 (1.02-300) respectively. Using best fitting parameters we find the costs incurred are between £170 and £195 per abnormal smear due to infection with HPV 6/11. In England, the impact of cytological abnormalities due to HPV 6/11 is relatively small, but not negligible. A vaccine that protects against HPV 6/11 infections could reduce costs associated with borderline and mild dysplasia, and associated colposcopies. These benefits should be considered when formulating immunisation policy, if possible. Smears and colposcopies in those uninfected with HPV far outnumber those in women infected with HPV 6/11.

Hypohidrotic ectodermal dysplasia, a potentially life-threatening heritable disorder, may be recognized already in utero by characteristic features such as oligodontia and mandibular hypoplasia. As therapeutic options and prognosis depend on the time point of diagnosis, early recognition was attempted during routine prenatal ultrasound examinations. Fetuses of nine pregnant women (one triplet and eight singleton pregnancies) with family histories of hypohidrotic ectodermal dysplasia were investigated by sonography between the 20th and 24th week of gestation. In 4 male and 2 female fetuses reduced amounts of tooth germs were detected, whereas 5 fetal subjects showed the normal amount. Three-dimensional ultrasound evaluation revealed mandibular hypoplasia in 5 of the 6 fetuses with oligodontia. Molecular genetic analysis and/or clinical findings after birth confirmed the prenatal sonographic diagnosis in each subject. In subjects with a family history of hypohidrotic ectodermal dysplasia, the diagnosis of this rare condition can be established noninvasively by sonography in the second trimester of pregnancy. Early recognition of the disorder may help to prevent dangerous hyperthermic episodes in infancy and may allow timely therapeutic interventions. © Georg Thieme Verlag KG Stuttgart · New York.

Septo-optic dysplasia (SOD) is a heterogeneous developmental malformation characterized by optic nerve hypoplasia associated with dysgenesis of the septum pellucidum and other cerebral malformations. The clinical manifestations include psychomotor retardation, visual impairment, thermoregulatory disturbances, conjugated hyperbilirubinemia and seizures. In 2000, Miller et al. first named the association of SOD and cortical dysplasia as SOD-plus. In this report, all the cases had severe clinical impairment, presenting global developmental delay and spastic motor deficits. Subsequent reports of SOD-plus also stressed the psychomotor development delay, spastic motor deficits and seizures seen in these patients, emphasizing the severity of the brain involvement. Recently, Kwak et al. reported a case of SOD-plus presenting with cortical dysplasia involving the insular cortex bilaterally. However, differently from all the previous reports, the patient had no signs or symptoms of cortical dysfunction, except for one episode of seizure. We report an additional case of SOD-plus, which presented extensive cortical malformation, with no signs or symptoms of cortical dysfunction. We suggest that similar to the classical form of SOD, the clinical presentation in patients with SOD-plus can also range from mild to extremely severe. (author)

To evaluate the diagnostic accuracy of MR imaging in the identification of labral and articular cartilage lesions in patients with acetabular dysplasia. Pre-operative MR imaging was performed on 27 hips in 25 consecutive patients (16 males, 9 females, age range 19-52 years, mean age 31.2 years) with radiographic evidence of acetabular dysplasia (centre-edge angle of Wiberg <20 degrees). The average duration of symptoms was 16.2 months. Two musculoskeletal radiologists assessed MR images in consensus for the presence of abnormality involving the acetabular labrum and adjacent acetabular articular cartilage. A high resolution, non-arthrographic technique was used to assess the labrum and labral chondral transitional zone. Surgical correlation was obtained in all cases by a single surgeon experienced in hip arthroscopy and ten patients with normal hip MRI were included to provide a control group. The acetabular labra in the dysplastic hips demonstrated abnormal signal intensity, and had an elongated appearance when compared with the control group (mean length 10.9 mm vs 6.4 mm). Morphological appearances in the labra included surface irregularity, fissures and cleft formation. MR imaging correctly identified the severity of chondral abnormality in 24 of 27 hips (89%) when compared with arthroscopic findings. MR imaging demonstrates an elongated labrum, focal intra-substance signal change and irregularity and fissuring of the margins in patients with acetabular dysplasia. Abnormality is also identified at the labral chondral transitional zone, where fissuring, focal clefts, chondral deficiency and subchondral cyst formation may be apparent. A high-resolution, non-arthrographic technique can provide an accurate preoperative assessment and evaluate the presence of premature osteoarthritis. (orig.)

To evaluate the diagnostic accuracy of MR imaging in the identification of labral and articular cartilage lesions in patients with acetabular dysplasia. Pre-operative MR imaging was performed on 27 hips in 25 consecutive patients (16 males, 9 females, age range 19-52 years, mean age 31.2 years) with radiographic evidence of acetabular dysplasia (centre-edge angle of Wiberg <20 degrees). The average duration of symptoms was 16.2 months. Two musculoskeletal radiologists assessed MR images in consensus for the presence of abnormality involving the acetabular labrum and adjacent acetabular articular cartilage. A high resolution, non-arthrographic technique was used to assess the labrum and labral chondral transitional zone. Surgical correlation was obtained in all cases by a single surgeon experienced in hip arthroscopy and ten patients with normal hip MRI were included to provide a control group. The acetabular labra in the dysplastic hips demonstrated abnormal signal intensity, and had an elongated appearance when compared with the control group (mean length 10.9 mm vs 6.4 mm).

Objective. The objective of this study was to review the problem of lumbar gibbus in children with storage diseases and bone dysplasias utilizing plain films and MR imaging. Materials and methods. Clinical histories and radiographic images in five patients with storage diseases [four mucopolysaccharidosis (MPS) and one mucolipidosis] and two with achondroplasia were reviewed. The International Skeletal Dysplasia Registry (Los Angeles, Calif.), surveyed for all patients with lumbar gibbus and skeletal dysplasias, provided 12 additional cases. Results. All patients had localized gibbus of the upper lumbar spine, characterized by anterior wedging and posterior displacement of the vertebrae at the apex of the curve, producing a beaked appearance. The curve, exaggerated in the sitting or standing position, was most severe in the two patients with MPS-IV (one of whom died). Both developed severe neurologic signs and symptoms requiring surgical intervention. In four patients, MR images demonstrated the apex of the curve to be at or below the conus. Two patients demonstrated anterior herniation of the intervertebral discs at the apex of the curve, though the signal intensity of the intervertebral discs was normal. Conclusion. Lumbar gibbus has important neurologic and orthopedic implications, and is most severe in patients with MPS. The etiology of the gibbus with vertebral beaking is multifactorial and includes poor truncal muscle tone, weight-bearing forces, growth disturbance and anterior disc herniation. The curve is generally at or below the conus. Neurologic complications are unusual, although orthopedic problems can arise. Due to their longer survival, patients with achondroplasia or Morquio`s disease are more vulnerable to eventual gibbus-related musculoskeletal complications. (orig.). With 6 figs., 2 tabs.

Full Text Available The objective of this study was to determine the demographic, clinical and survival characteristics and to identify risk factors for mortality due to tricuspid valve dysplasia in UK dogs. Records of client-owned dogs diagnosed with tricuspid valve dysplasia at a referral centre were retrospectively reviewed. Only dogs diagnosed with tricuspid valve dysplasia based on the presence of a right-sided heart murmur identified prior to one year of age, and confirmed with Doppler echocardiography, were included. Dogs with concomitant cardiac diseases, pulmonary hypertension and/or trivial tricuspid regurgitation were excluded. Analysed data included signalment, reason for presentation, clinical signs, electrocardiographic and echocardiographic features, survival status and cause of death. Survival times and risk factors for mortality were evaluated using Kaplan-Meier curves and Cox regression. Eighteen dogs met inclusion criteria. Border collies were over-represented (p= 0.014. Dogs were most frequently referred for investigation of heart murmur. The most common arrhythmia was atrial fibrillation (n=3. Median survival time from diagnosis of tricuspid valve dysplasia was 2775 days (range 1-3696 days; 95% CI 1542.41-4007.59 and from onset of right-sided congestive heart failure was 181 days (range 1-2130 days; 95% CI 0-455.59. Syncope was the sole risk factor for cardiac death. In this population of UK dogs, tricuspid valve dysplasia was uncommon but, when severe, frequently led to right-sided congestive heart failure. Prognosis was favourable for mild and moderate tricuspid dysplasia. Survival time was reduced with right-sided congestive heart failure but varied widely. Risk of cardiac death was significantly increased if syncope had occurred.

Background and objectives Atypical hemolytic uremic syndrome is characterized by vascular endothelial damage caused by complement dysregulation. Consistently, complement inhibition therapies are highly effective in most patients with atypical hemolytic uremic syndrome. Recently, it was shown that a significant percentage of patients with early-onset atypical hemolytic uremic syndrome carry mutations in diacylglycerol kinase-ε, an intracellular protein with no obvious role in complement. These data support an alternative, complement-independent mechanism leading to thrombotic microangiopathy that has implications for treatment of early-onset atypical hemolytic uremic syndrome. To get additional insights into this new form of atypical hemolytic uremic syndrome, the diacylglycerol kinase-ε gene in a cohort with atypical hemolytic uremic syndrome was analyzed. Design, setting, participants, & measurements Eighty-three patients with early-onset atypical hemolytic uremic syndrome (<2 years) enrolled in the Spanish atypical hemolytic uremic syndrome registry between 1999 and 2013 were screened for mutations in diacylglycerol kinase-ε. These patients were also fully characterized for mutations in the genes encoding factor H, membrane cofactor protein, factor I, C3, factor B, and thrombomodulin CFHRs copy number variations and rearrangements, and antifactor H antibodies. Results Four patients carried mutations in diacylglycerol kinase-ε, one p.H536Qfs*16 homozygote and three compound heterozygotes (p.W322*/p.P498R, two patients; p.Q248H/p.G484Gfs*10, one patient). Three patients also carried heterozygous mutations in thrombomodulin or C3. Extensive plasma infusions controlled atypical hemolytic uremic syndrome recurrences and prevented renal failure in the two patients with diacylglycerol kinase-ε and thrombomodulin mutations. A positive response to plasma infusions and complement inhibition treatment was also observed in the patient with concurrent diacylglycerol

Development of angle-resolved low coherence interferometry for clinical detection of dysplasia

Directory of Open Access Journals (Sweden)

Yizheng Zhu

2011-01-01

Full Text Available This review covers the development of angle-resolved low coherence interferometry (a/LCI from initial development through clinical application. In the first applications, the approach used a time-domain interferometry scheme and was validated using animal models of carcinogenesis to assess the feasibility of detecting dysplasia in situ. Further development of the approach led to Fourier-domain interferometry schemes with higher throughput and endoscope-compatible probes to enable clinical application. These later implementations have been applied to clinical studies of dysplasia in Barrett′s esophagus tissues, a metaplastic tissue type that is associated with an increased risk of esophageal adenocarcinoma. As an alternative to systematic biopsy, the a/LCI approach offers high sensitivity and specificity for detecting dysplasia in these tissues while avoiding the need for tissue removal or exogenous contrast agents. Here, the various implementations of a/LCI are discussed and the results of the preliminary animal experiments and ex vivo human tissue studies are reviewed. A review of a recent in vivo clinical study is also presented.

Objective. Arguing that additional symptoms should be added to the criteria for atypical depression. Method. Published research articles on atypical depression are reviewed. Results. (1) The original studies upon which the criteria for atypical depression were based cited fatigue, insomnia, pain, and loss of weight as characteristic symptoms. (2) Several studies of DSM depressive criteria found patients with atypical depression to exhibit high levels of insomnia, fatigue, and loss of appetite/weight. (3) Several studies have found atypical depression to be comorbid with headaches, bulimia, and body image issues. (4) Most probands who report atypical depression meet criteria for "somatic depression," defined as depression associated with several of disordered eating, poor body image, headaches, fatigue, and insomnia. The gender difference in prevalence of atypical depression results from its overlap with somatic depression. Somatic depression is associated with psychosocial measures related to gender, linking it with the descriptions of atypical depression as "reactive" appearing in the studies upon which the original criteria for atypical depression were based. Conclusion. Insomnia, disordered eating, poor body image, and aches/pains should be added as criteria for atypical depression matching criteria for somatic depression defining a reactive depressive disorder possibly distinct from endogenous melancholic depression.

2016-01-01

Full Text Available The paper is devoted to the study of the rate of urinary tract abnormalities and kidney functions in children with mild, moderate, and severe connective tissue dysplasia. Severe connective tissue dysplasia was found to prevail in children with urinary tract abnormalities and to be characterized by a variety of urodynamic urinary tract abnormalities. Urinary system infection occurred equally frequently in both patient groups and its rate did not depend on the degree of the dysplasia. Some children with severe connective dysplasia were noted to have diminished renal filtration function. High-grade vesicoureteral reflux, tubular disorders as nocturias, and lowered urine osmolarity were more common in children with severe dysplasia. Hypertension was seen equally often in both patient groups, no matter what the degree of connective tissue dysplasia.

Delayed Recurrence of Atypical Pulmonary Carcinoid Cluster: A Rare Occurrence

Salim Surani

2014-01-01

Full Text Available Carcinoid is one of the most common tumors of the gastrointestinal tract followed by the tracheobronchial tree. Bronchial carcinoid compromises 20% of total carcinoid and accounts for 1–5% of pulmonary malignancies. Carcinoid can be typical or atypical, with atypical carcinoid compromises 10% of the carcinoid tumors. Carcinoid usually presents as peripheral lung lesion or solitary endobronchial abnormality. Rarely it can present as multiple endobronchial lesion. We hereby present a rare case of an elderly gentleman who had undergone resection of right middle and lower lobe of lung for atypical carcinoid. Seven years later he presented with cough. CT scan of chest revealed right hilar mass. Flexible bronchoscopy revealed numerous endobronchial polypoid lesions in the tracheobronchial tree. Recurrent atypical carcinoid was then confirmed on biopsy.

Fibrous dysplasia is a common benign disorder of bone in which fibro-osseous tissue replaces bone spongiosa. Lesions have a typical appearance on computed tomography (CT) images and regularly show a markedly increased uptake in bone scintigraphy using {sup 99m}Tc-labelled methylene diphosphonate ({sup 99m}Tc-MDP) as radiotracer. The glucose avidity of these lesions depicted by positron emission tomography (PET) using the radiolabelled glucose derivative {sup 18}F-fluoro-2-deoxy-glucose (FDG) is less well known since FDG-PET does not have a role in the assessment of this disease. However, single cases have been reported in which fibrous dysplasia was present in patients undergoing FDG-PET scanning for oncological reasons, and no significant FDG uptake was observed for lesions identified as fibrous dysplasia. We report on a 24-year-old man with known fibrous dysplasia who underwent combined FDG-PET/CT scanning because of suspected recurrence of testicular cancer. In contrast to prior reports, a markedly elevated uptake of FDG was seen in numerous locations that were identified as fibrous dysplasia by CT. Based on this result, we conclude that fibrous dysplasia may mimick malignancy in FDG-PET and that coregistered CT may help to resolve these equivocal findings. (orig.)

We describe a series of cases of syphilis with atypical extracutaneous clinical presentation diagnosed in HIV-infected patients. Retrospective observational study. All cases of syphilis diagnosed in HIV-infected patients during the period between June 2013 and June 2016 in a tertiary hospital of the Barcelona metropolitan area were analysed. A total of 71 cases of syphilis were diagnosed, 32 of them presenting with clinical signs or symptoms. Seven of these cases (9.8% of the total and 21.8% of the symptomatic cases) had atypical presentations with extracutaneous involvement: ocular (4), gastric (1), multiple hepatic abscesses (1) and generalised adenopathies (1). Patients were treated with intramuscular or intravenous penicillin and the clinical and serological evolution was good in all of them. Extracutaneous atypical clinical presentations were observed in 21.8% of symptomatic cases of syphilis in HIV+ patients with ocular involvement being the most freqent.

2013-01-01

Objective This study examined the characteristics and outcomes of patients with major depressive disorder (MDD), with or without atypical features, who were treated with acute bilateral electroconvulsive therapy (ECT). Method Analyses were conducted with 489 patients who met DSM-IV criteria for MDD. Subjects were identified as typical or atypical on the basis of the Structured Clinical Interview for DSM-IV obtained at baseline prior to ECT. Depression symptom severity was measured by the 24-item Hamilton Rating Scale for Depression (HAM-D24) and the 30-item Inventory of Depressive Symptomatology–Self-Report (IDS-SR30). Remission was defined as at least a 60% decrease from baseline in HAM-D24 score and a total score of 10 or below on the last 2 consecutive HAM-D24 ratings. The randomized controlled trial was performed from 1997 to 2004. Results The typical (N = 453) and atypical (N = 36) groups differed in several sociodemographic and clinical variables including gender (p = .0071), age (p = .0005), treatment resistance (p = .0014), and age at first illness onset (p < .0001) and onset of current episode (p = .0008). Following an acute course of bilateral ECT, a considerable portion of both the typical (67.1%) and the atypical (80.6%) groups reached remission. The atypical group was 2.6 (95% CI = 1.1 to 6.2) times more likely to remit than the typical group after adjustment for age, psychosis, gender, clinical site, and depression severity based on the HAM-D24. Conclusion Acute ECT is an efficacious treatment for depressed patients with typical or atypical symptom features. PMID:18278988

We describe a familial syndrome of renal dysplasia, Wilms tumor, hyperplasia of the endocrine pancreas, fetal gigantism, multiple congenital anomalies and mental retardation. This condition was previously described by Perlman et al [1973, 1975] and we propose to call it the "Perlman syndrome." It appears to be transmitted as an autosomal recessive trait. The possible relationships between dysplasia, neoplasia and malformation are discussed.

Overexpression of Shox2 Leads to Congenital Dysplasia of the Temporomandibular Joint in Mice

Directory of Open Access Journals (Sweden)

Xihai Li

2014-07-01

Full Text Available Our previous study reported that inactivation of Shox2 led to dysplasia and ankylosis of the temporomandibular joint (TMJ, and that replacing Shox2 with human Shox partially rescued the phenotype with a prematurely worn out articular disc. However, the mechanisms of Shox2 activity in TMJ development remain to be elucidated. In this study, we investigated the molecular and cellular basis for the congenital dysplasia of TMJ in Wnt1-Cre; pMes-stop Shox2 mice. We found that condyle and glenoid fossa dysplasia occurs primarily in the second week after the birth. The dysplastic TMJ of Wnt1-Cre; pMes-stop Shox2 mice exhibits a loss of Collagen type I, Collagen type II, Ihh and Gli2. In situ zymography and immunohistochemistry further demonstrate an up-regulation of matrix metalloproteinases (MMPs, MMP9 and MMP13, accompanied by a significantly increased cell apoptosis. In addition, the cell proliferation and expressions of Sox9, Runx2 and Ihh are no different in the embryonic TMJ between the wild type and mutant mice. Our results show that overexpression of Shox2 leads to the loss of extracellular matrix and the increase of cell apoptosis in TMJ dysplasia by up-regulating MMPs and down-regulating the Ihh signaling pathway.

Protein-losing enteropathy is a primary or secondary manifestation of a group of conditions, and etiologies which are broadly divisible into those with mucosal injury on the basis of inflammatory and ulcerative conditions, mucosal injury without erosions or ulcerations, and lymphatic abnormalities. We describe the first case of protein-losing enteropathy in a pediatric patient, with severe skeletal dysplasia consistent with thanatophoric dysplasia type I and DNA analysis that revealed a c.1949A>T (p.Lys650Met) in exon 15 of the FGFR3 gene. She presented with protein-losing enteropathy in her 6th month. Post-mortem examination revealed lymphangiectasia in the small intestine. To our knowledge, this is the first report of intestinal lymphangiectasia as a complication of skeletal dysplasia resulting in severe protein-losing enteropathy. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Determining and understanding the definition of real estate, the complexity and diversity of these objects, a growing appearance of so-called atypical properties (such as sport stadiums, roads, boreholes, analyzing legislation and judicial practice of this field – all these issues call for a deep study of this topic. There is a conflicting arbitration practice, the subject of which is the learning of the legal nature of atypical real estate (for instance, asphalt playgrounds, car parks, fences, wells. The object of the research is the learning of the legal status of atypical real estate.

Fluid and electrolyte balance during the first week of life and risk of bronchopulmonary dysplasia in the preterm neonate

Directory of Open Access Journals (Sweden)

Gustavo Rocha

2010-01-01

Full Text Available BACKGROUND: Early fluid and electrolyte imbalances may be associated with an increased risk of bronchopulmonary dysplasia. OBJECTIVE: We sought to establish an association between fluid and electrolyte balance in the first week of life and the risk of bronchopulmonary dysplasia. METHODS: Clinical charts of 205 neonates <32 weeks gestational age and/or <1,250 g birth weight (admitted to our NICU between 1997 and 2008 were analyzed. Clinical features, fluid and electrolyte balance were analyzed for the first 7 days of life using multivariate models of generalized estimation equations. A p value <0.05 was considered significant in all of the hypothesis tests. RESULTS: The prevalence of bronchopulmonary dysplasia was 22%. Lower gestational age and birth weight, male gender, less frequent use of antenatal steroids, respiratory distress syndrome, use of surfactant, patent ductus arteriosus, duration of invasive ventilation and NICU stay were significantly associated with bronchopulmonary dysplasia. The variation in serum values of potassium, phosphorus and creatinine during the first week of life also revealed an association with bronchopulmonary dysplasia. Higher mean plasma calcium values were associated with spontaneous closure of the patent ductus arteriosus. The use of indomethacin to induce patent ductus arteriosus closure was significantly higher in bronchopulmonary dysplasia patients. CONCLUSIONS: Differences in renal function and tubular handling of potassium and phosphorus are present during the first week of life among preterm neonates who will develop bronchopulmonary dysplasia. The higher rate of patent ductus arteriosus and indomethacin use may influence these differences. Serum levels of calcium also appear to play a role in spontaneous ductus arteriosus closure.

Florid cemento-osseous dysplasia (FCOD) is one of the uncommon dysplasias affecting the maxillofacial region. The age group may vary from 19 to 76 years and typically presents in the 4th and 5th decades. In most cases patients do not have hereditary basis of disease, and only a few familial cases have been documented. As far as we know this is the 1st reported case of familial FCOD in an Indian family. The mother and son exhibited multiple sclerotic masses in both jaws. The mode of transmission appeared to be autosomal dominant with variable phenotypic expression. PMID:23198165

Radiographic features of spondylo-epimetaphyseal dysplasia with joint laxity and progressive kyphoscoliosis

Kozlowski, K.; Beighton, P.

1984-01-01

We have reviewed the radiographic features of 19 patients with spondyloepimetaphyseal dysplasia with joint laxity (SEMDJL). The salient, diagnostic radiographic manifestations are mild to moderate spondylo-epimetaphyseal dysplasia, progressive infantile kyphoscoliosis, characteristic pelvic, forearm and elbow changes and a highly abnormal bony trabecular pattern. The condition, which is inherited as an autosomal recessive, has only been observed in South Africa among Caucasians, several of whom have German names or German connections. The authors wish to bring the condition to the attention of European radiologists in an attempt to determine the geographic origin of the faulty gene. (orig.) [de

Full Text Available Congenital Disorder of Glycosylation type Ig (ALG12-CDG is part of a group of autosomal recessive conditions caused by deficiency of proteins involved in the assembly of dolichol-oligosaccharides used for protein N-glycosylation. In ALG12-CDG, the enzyme affected is encoded by the ALG12 gene. Affected individuals present clinically with neurodevelopmental delay, growth retardation, immune deficiency, male genital hypoplasia, and cardiomyopathy. A total of six individuals have been reported in the literature. Here, we present an infant with rhizomelic short stature, talipes equinovarus, platyspondyly, and joint dislocations. The infant had marked under-ossification of the pubic bones. Exome sequencing was performed and two deletions, each resulting in a frameshift, were found in ALG12. A review of the literature revealed two infants with ALG12-CDG and a severe skeletal dysplasia, including under-ossification of cervical vertebrae, pubic bones, and knees; in addition to talipes equinovarus and rhizomelic short stature. The phenotype of the individual we describe resembles pseudodiastrophic dysplasia and we discuss similarities and differences between ALG12-CDG and pseudodiastrophic dysplasia. The differential diagnosis in selected undiagnosed skeletal dysplasias should include CDGs.

Cleidocranial dysplasia (CCD) is a rare autosomal dominant skeletal dysplasia characterized by hypoplastic clavicles, late closure of the fontanels, dental problems and other skeletal features. CCD is caused by mutations, deletions or duplications in runt-related transcription factor 2 (RUNX2), which encodes for a protein essential for osteoblast differentiation and chondrocyte maturation. We describe three familial cases of CCD, misdiagnosed as rickets over three generations. No mutations were detected on standard DNA sequencing of RUNX2, but a novel deletion was identified on quantitative polymerase chain reaction (qPCR) and multiple ligation-dependent probe amplification (MLPA). The present cases indicate that CCD could be misdiagnosed as rickets, leading to inappropriate treatment, and confirm that mutations in RUNX2 are not able to be identified on standard DNA sequencing in all CCD patients, but can be identified on qPCR and MLPA. © 2015 Japan Pediatric Society.

To correlate the atypical sonographic patterns of fibroadenoma of the breast with the pathologic findings. Among 203 surgically proven 43 which were sonographically atypical fibroadenomas, were retrospectively reviewed. The diagnostic criteria for atypical variety, as seen on sonography, were an ill-defined margin, microlobulated or irregular shape, heterogeneous internal echo-pattern, posterior shadowing, microcalcification, and clefts. The atypical sonographic patterns of these 43 fibroadenomas were analysed and compared with the pathologic findings. Among 43 lesions, ill-defined margins or irregular shapes were seen in 15 cases, heterogeneous internal echo-patterns in 27, posterior attenuation in nine, and clefts in seven. Thirty-seven (86%) of the 43 were predominantly ductal or had a mixed ductal and stromal component. Eleven (73.3%) of fifteen ill-defined margin or irregular shaped lesions were caused by interdigitation of surrounding normal breast parenchyma and mass. Twenty two (81.5%) of 27 heterogeneous internal echo-pat-terns were related to dilated ducts, phyllodes features, collagen bundles, adenosis, microcalcification, or fat vacuoles. Eight (88.9%) of nine posterior attenuations were caused by collagen bundles, microcalcification, ductal proliferation or dilatation. All seven cases showing clefts revealed phyllodes features and dilated ducts. Most atypical fibroadenomas had a predominantly ductal or mixed component. Ill-defined margin or irregular shape was mainly due to interdigitation of normal surrounding parenchyma. Variable histologic features were related to the heterogeneous internal echo-pattern, posterior shadowing, and the clefts revealed by atypical sonographic findings.

Retrospective series have shown the efficacy of endoscopic spray cryotherapy in eradicating high-grade dysplasia (HGD) in Barrett's esophagus (BE); however, prospective data are lacking, and efficacy for low-grade dysplasia (LGD) is unclear. The aim of this study was to assess the efficacy and safety of spray cryotherapy in patients with LGD or HGD. A multicenter, prospective open-label registry enrolled patients with dysplastic BE. Spray cryotherapy was performed every 2-3 months until there was no endoscopic evidence of BE and no histological evidence of dysplasia, followed by surveillance endoscopies up to 2 years. Primary outcome measures were complete eradication of dysplasia (CE-D) and complete eradication of all intestinal metaplasia (CE-IM). Ninety-six subjects with Barrett's dysplasia (67% HGD; 65% long-segment BE; mean length 4.5 cm) underwent 321 treatments (mean 3.3 per subject). Mean age was 67 years, 83% were male. Eighty patients (83%) completed treatment with follow-up endoscopy (mean duration 21 months). In patients with LGD, rate of CE-D was 91% (21/23) and rate of CE-IM was 61% (14/23). In HGD, CE-D rate was 81% (46/57) and CE-IM was 65% (37/57). In patients with short-segment BE (SSBE) with any dysplasia, CE-D was achieved in 97% (30/31) and CE-IM in 77% (24/31). There were no esophageal perforations or related deaths. One subject developed a stricture, which did not require dilation. One patient was hospitalized for bleeding in the setting of non-steroidal anti-inflammatory drug use. In the largest prospective cohort to date, data suggest endoscopic spray cryotherapy is a safe and effective modality for eradication of BE with LGD or HGD, particularly with SSBE. © 2015 International Society for Diseases of the Esophagus.

Pelvic proportions in x-ray pictures of german shepherd dog, rottweiler and great dane, a contribution to hip dysplasia

Energy Technology Data Exchange (ETDEWEB)

Koeppel, E. (Veterinaermedizinische Univ., Vienna (Austria))

1983-01-01

Measurements of length and breadth were done in 439 X-ray pictures of the pelvis of German Shepherd Dog, Rottweiler and Great Dane. The relation of pelvic proportions to hip dysplasia was checked. In 66 X-ray pictures of the pelvis of young dogs the ischiadic part of the acetabulum was measured. In all breeds the ischium formed 68,8 percent of the acetabulum. Ilium and ischium showed changes in relation to hip dysplasia, which could be proved unequivocally only in Rottweilers. Changes of pelvic proportions in other breeds were not perceived. In Rottweilers also those changes can be seen distinctly only in severe cases of hip dysplasia. For the special case valid accordance with any degree of hip dysplasia could not be found.

Ocular surface involvements in ectrodactyly-ectodermal dysplasia-cleft syndrome.

Kennedy, David P; Chandler, John W; McCulley, James P

To present the ocular manifestation of 2 cases of ectrodactyly-ectodermal dysplasia-cleft syndrome, a multiple congenital anomaly syndrome caused by a single point mutation of the p63 gene that controls epidermal development and homeostasis and to present treatment options. Patient 1 presented with mild signs and symptoms of dry eye and limbal stem cell deficiency with retention of 20/30 vision. Patient 2 presented with severe signs and symptoms of limbal stem cell deficiency with diffuse corneal scarring and counting fingers vision. This second patient's course was complicated by allergic conjunctivitis and advanced steroid-induced glaucoma. The cause of visual loss in ectrodactyly-ectodermal dysplasia-cleft syndrome appears to be multifactorial and likely includes inflammation of the ocular surface, tear film abnormalities, eyelid abnormalities, and limbal stem cell deficiency. Treatment modalities including lubrication, contact lenses, and limbal stem cell transplantation are reviewed. The ophthalmic conditions seen in ectrodactyly-ectodermal dysplasia-cleft syndrome frequently lead to vision loss. Early correct diagnosis and appropriate therapy are paramount because p63 gene mutations have a critical role in maintaining the integrity of the ocular surface in the setting of limbal stem cell deficiency, especially if there are other ocular surface insults such as lid disease, meibomian gland dysfunction and toxicity from topical medications. Patients should be monitored at regular, frequent intervals; and particular attention should be taken to avoid adverse secondary effects of these conditions and medications.

Full Text Available Oculodentodigital dysplasia (ODDD, also known as oculodento-osseous dysplasia, is an extremely rare autosomal dominant disorder with high penetrance, intra- and interfamilial phenotypic variability, and advanced paternal age in sporadic cases. The incidence of this disease is not precisely known, with only 243 cases reported in the scientific literature, suggesting an incidence of around 1 in 10 million people. It is marked mainly by eye abnormalities, craniofacial dysmorphism, dental anomalies, hand and foot malformations, various skeletal defects, and mildly delayed mental development. Neurological changes may appear earlier in each subsequent generation. This case report describes a radiological diagnosis of ODDD based on physical appearance, clinical features and radiographic findings in a 16-year-old girl.

Cohort study of atypical pressure ulcers development.

Jaul, Efraim

2014-12-01

Atypical pressure ulcers (APU) are distinguished from common pressure ulcers (PU) with both unusual location and different aetiology. The occurrence and attempts to characterise APU remain unrecognised. The purpose of this cohort study was to analyse the occurrence of atypical location and the circumstances of the causation, and draw attention to the prevention and treatment by a multidisciplinary team. The cohort study spanned three and a half years totalling 174 patients. The unit incorporates two weekly combined staff meetings. One concentrates on wound assessment with treatment decisions made by the physician and nurse, and the other, a multidisciplinary team reviewing all patients and coordinating treatment. The main finding of this study identified APU occurrence rate of 21% within acquired PU over a three and a half year period. Severe spasticity constituted the largest group in this study and the most difficult to cure wounds, located in medial aspects of knees, elbows and palms. Medical devices caused the second largest occurrence of atypical wounds, located in the nape of the neck, penis and nostrils. Bony deformities were the third recognisable atypical wound group located in shoulder blades and upper spine. These three categories are definable and time observable. APU are important to be recognisable, and can be healed as well as being prevented. The prominent role of the multidisciplinary team is primary in identification, prevention and treatment. © 2013 The Authors.

KDF1, encoding keratinocyte differentiation factor 1, is mutated in a multigenerational family with ectodermal dysplasia

KAUST Repository

Shamseldin, Hanan E.

2016-11-12

Ectodermal dysplasia is a highly heterogeneous group of disorders that variably affect the derivatives of the ectoderm, primarily skin, hair, nails and teeth. TP63, itself mutated in ectodermal dysplasia, links many other ectodermal dysplasia disease genes through a regulatory network that maintains the balance between proliferation and differentiation of the epidermis and other ectodermal derivatives. The ectodermal knockout phenotype of five mouse genes that regulate and/or are regulated by TP63 (Irf6, Ikkα, Ripk4, Stratifin, and Kdf1) is strikingly similar and involves abnormal balance towards proliferation at the expense of differentiation, but only the first three have corresponding ectodermal phenotypes in humans. We describe a multigenerational Saudi family with an autosomal dominant form of hypohidrotic ectodermal dysplasia in which positional mapping and exome sequencing identified a novel variant in KDF1 that fully segregates with the phenotype. The recapitulation of the phenotype we observe in this family by the Kdf1−/− mouse suggests a causal role played by the KDF1 variant.
