introduction: leukoplakia is the most common precancerous lesion of the oral mucosa and may range microscopically form benign hyperkeratosis to invasive squamous cell carcinoma. p53 is a tumor suppressor protein; whereas, proliferative cell nuclear antigen (pcna) is a proliferative marker. the aim of this study was to evaluate the immunohistochemical expressions of p53 and pcna in oral leukopla...
schimke immuno-osseous dysplasia is a rare autosomal recessive multisystem disorder characterized by steroid-resistant nephrotic syndrome, immunodeficiency, and spondyloepiphy-seal dysplasia. mutations in swi/snf2 related, matrix associated, actin dependent regulator of chromatin, subfamily a-like 1 (smarcal1) gene are responsible for the disease. the present report describes, for the first tim...
it is sometimes difficult to recognize a jaw lesion as osteosarcoma, ossifying fibroma or fibrous dysplasia in routine hematoxylin and eosin staining and a more accurate technique is needed to differentiate these lesions. many studies have shown the potential usefulness of silver-stained nucleolar organizer region (agnor) parameters for the diagnosis of various neoplasms. this study was car...
Çamptomelic dysplasia is a fatal infantile dysplasia characterized by lower limb bowing and mesomelic dwarfism. Most of this skeletal dysplasia occur through spontaneous mutation, but recessive autosomic recession is also likely. Prenatal diagnosis is considered with ultrasonography and amniocentesis. Postnatal diagnosis is characterized by mesomelic dwarfism with limb bowing, pulmonary h...
OBJECTIVES. To clarify the use of ultrasonography by determining the frequency of developmental dysplasia of the hip among breech-presented Chinese neonates in Hong Kong. DESIGN. Prospective case series. SETTING. Regional hospital, Hong Kong. PATIENTS. All breech-presented Chinese neonates born during January 2008 to June 2009 were included (except premature neonates). They were examined clinic...
Apoptosis and proliferation are processes associated with the development and progression of breast cancer. The sensitivity of tumour cells to the induction of apoptosis depends on the balance between pro- and anti-apoptotic proteins. The expression of Bak and Bcl-2 was examined using an immunohistochemical method in 71 primary breast cancers. Furthermore, Bcl-2 and Bak were assessed in the nor...
OBJECTIVE To improve the prenatal diagnosis of thanatophoric dysplasia by defining the change in fetal size across gestation and the frequency of sonographic features, and developing non-invasive molecular genetic diagnosis based on cell-free fetal DNA (cffDNA) in maternal plasma. METHODS Fetuses with a confirmed diagnosis of thanatophoric dysplasia were ascertained, records reviewed, sonogra...
in this case report we will describe a rare association between anhyrotic ectodermal dysplasia (aed) and immunodeficiency and autoimmunity [in our case: idiopathic thrombocytopenic purpura (itp) and crohn disease]. aed is a rare congenital disorder characterized by sparse hair, abnormal teeth and anhidrosis due to lack of eccrine glands. the survey of 87 cases with (aed) revealed only one irrit...
Transmantle dysplasia is a rare type of focal cortical dysplasia (FCD) characterized by expansion of the cortex from the deep white matter to the surface and in which there is a FCD IIA or IIB pathologic pattern. To characterize possible mechanisms underlying this regional disorder of radial migrating cells, we studied the expression patterns of neocortical layer-specific markers using immunohi...
