Neoplasms of the bony orbit and contents except the eyeball.
Orbital Diseases
Diseases of the bony orbit and contents except the eyeball.
Orbit
Bony cavity that holds the eyeball and its associated tissues and appendages.
Orbital Fractures
Fractures of the bones in the orbit, which include parts of the frontal, ethmoidal, lacrimal, and sphenoid bones and the maxilla and zygoma.
Orbital Pseudotumor
A nonspecific tumor-like inflammatory lesion in the ORBIT of the eye. It is usually composed of mature LYMPHOCYTES; PLASMA CELLS; MACROPHAGES; LEUKOCYTES with varying degrees of FIBROSIS. Orbital pseudotumors are often associated with inflammation of the extraocular muscles (ORBITAL MYOSITIS) or inflammation of the lacrimal glands (DACRYOADENITIS).
Orbital Cellulitis
Inflammation of the loose connective tissues around the ORBIT, bony structure around the eyeball. It is characterized by PAIN; EDEMA of the CONJUNCTIVA; swelling of the EYELIDS; EXOPHTHALMOS; limited eye movement; and loss of vision.
Exophthalmos
Abnormal protrusion of both eyes; may be caused by endocrine gland malfunction, malignancy, injury, or paralysis of the extrinsic muscles of the eye.
Graves Ophthalmopathy
An autoimmune disorder of the EYE, occurring in patients with Graves disease. Subtypes include congestive (inflammation of the orbital connective tissue), myopathic (swelling and dysfunction of the extraocular muscles), and mixed congestive-myopathic ophthalmopathy.
Eye, Artificial
A ready-made or custom-made prosthesis of glass or plastic shaped and colored to resemble the anterior portion of a normal eye and used for cosmetic reasons. It is attached to the anterior portion of an orbital implant (ORBITAL IMPLANTS) which is placed in the socket of an enucleated or eviscerated eye. (From Dorland, 28th ed)
Pancreatic Neoplasms
Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
Orbital Myositis
Inflammation of the extraocular muscle of the eye. It is characterized by swelling which can lead to ischemia, fibrosis, or ORBITAL PSEUDOTUMOR.
Neoplasms
New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.
Neoplasms, Cystic, Mucinous, and Serous
Neoplasms containing cyst-like formations or producing mucin or serum.
Oculomotor Muscles
The muscles that move the eye. Included in this group are the medial rectus, lateral rectus, superior rectus, inferior rectus, inferior oblique, superior oblique, musculus orbitalis, and levator palpebrae superioris.
Eye Enucleation
The surgical removal of the eyeball leaving the eye muscles and remaining orbital contents intact.
Orbit Evisceration
The surgical removal of the contents of the orbit. This includes the eyeball, blood vessels, muscles, fat, nerve supply, and periosteum. It should be differentiated from EYE EVISCERATION which removes the inner contents of the eye, leaving the sclera intact.
Eye Neoplasms
Tumors or cancer of the EYE.
Ophthalmologic Surgical Procedures
Surgery performed on the eye or any of its parts.
Neoplasms, Multiple Primary
Two or more abnormal growths of tissue occurring simultaneously and presumed to be of separate origin. The neoplasms may be histologically the same or different, and may be found in the same or different sites.
Skin Neoplasms
Tumors or cancer of the SKIN.
Tomography, X-Ray Computed
Tomography using x-ray transmission and a computer algorithm to reconstruct the image.
Diplopia
A visual symptom in which a single object is perceived by the visual cortex as two objects rather than one. Disorders associated with this condition include REFRACTIVE ERRORS; STRABISMUS; OCULOMOTOR NERVE DISEASES; TROCHLEAR NERVE DISEASES; ABDUCENS NERVE DISEASES; and diseases of the BRAIN STEM and OCCIPITAL LOBE.
Cellulitis
An acute, diffuse, and suppurative inflammation of loose connective tissue, particularly the deep subcutaneous tissues, and sometimes muscle, which is most commonly seen as a result of infection of a wound, ulcer, or other skin lesions.
Neoplasms, Second Primary
Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause.
Kidney Neoplasms
Tumors or cancers of the KIDNEY.
Graves Disease
A common form of hyperthyroidism with a diffuse hyperplastic GOITER. It is an autoimmune disorder that produces antibodies against the THYROID STIMULATING HORMONE RECEPTOR. These autoantibodies activate the TSH receptor, thereby stimulating the THYROID GLAND and hypersecretion of THYROID HORMONES. These autoantibodies can also affect the eyes (GRAVES OPHTHALMOPATHY) and the skin (Graves dermopathy).
Adenocarcinoma, Mucinous
An adenocarcinoma producing mucin in significant amounts. (From Dorland, 27th ed)
Thyroid Neoplasms
Tumors or cancer of the THYROID GLAND.
Myeloproliferative Disorders
Conditions which cause proliferation of hemopoietically active tissue or of tissue which has embryonic hemopoietic potential. They all involve dysregulation of multipotent MYELOID PROGENITOR CELLS, most often caused by a mutation in the JAK2 PROTEIN TYROSINE KINASE.
Eyelids
Each of the upper and lower folds of SKIN which cover the EYE when closed.
Lacrimal Apparatus Diseases
Diseases of the lacrimal apparatus.

Immunoglobulin VH gene expression among extranodal marginal zone B-cell lymphomas of the ocular adnexa. (1/350)

PURPOSE: Most lymphomas of the ocular adnexa are primary extranodal non-Hodgkin's lymphomas of the B-cell type, with the most common lymphoma subtype being the extranodal marginal-zone B-cell lymphoma (EMZL). Analysis of somatic mutations in the variable (V) region of the Ig heavy (H)-chain gene segment suggests that EMZL development in other locations is dependent on antigen stimulation. The purpose of this study was to analyze the presence of somatic hypermutations in clonally rearranged Ig H-chain V genes of this lymphoma entity in the ocular adnexa and to estimate whether the mutation pattern is compatible with antigen selection. METHODS: Twenty-six cases of EMZL of the ocular adnexa were diagnosed on the basis of morphology, histology, and immunohistology. A nested polymerase chain reaction (PCR) was performed on DNA extracted from paraffin sections. The isolated PCR products were sequenced and compared with published VH germline segments to determine the number of somatic mutations in the complementarity-determining region (CDR) 2 and framework (FW) region 3. RESULTS: The number of somatic mutations in the cases of EMZL varied between 0 and 24: Five cases involved 0 to 3 somatic mutations, and the remaining 21 cases involved 4 to 24 mutations. Based on the ratio of replacement (R) to silent (S) mutations in the CDR2 or FW3 regions, antigen selection seems to have occurred in 60% of ocular adnexal EMZL. The VH3 family was the most commonly expressed germline VH family (54%), followed by VH4 (23%), with biased usage of the latter. Some germline VH1 genes used included DP-8, DP-10, DP-53, DP-63 (VH4.21), and DP-49, which are frequently used by autoantibodies (e.g., rheumatoid factors) and natural autoantibodies. CONCLUSIONS: EMZLs of the ocular adnexa have an Ig H-chain mutation pattern that supports the concept that they represent a clonal expansion of post-germinal-center memory B-cells in most instances. In two thirds of cases, antigen selection may have occurred, and autoantibodies may have a role in their development.  (+info)

Prenatal sonographic features of embryonal rhabdomyosarcoma. (2/350)

We describe a case of fetal rhabdomyosarcoma detected during the third trimester of pregnancy by prenatal sonography. At 33 weeks' gestation, sonography performed because of suspected polyhydramnios showed a solid mass of 120 x 54 mm arising from the anterior wall of the fetal thoracic cage. Another mass within the left maxillary area which originated from the left orbital floor was also detected. In the abdomen, there were multiple round masses in and around the liver. As the previous scan at 28 weeks had appeared normal, the multiple masses which became visible and enlarged rapidly in different locations led us to believe that there was fetal cancer. The most likely diagnosis was rhabdomyosarcoma (which was later confirmed), because it is the most prevalent soft-tissue tumor in children and may develop within or outside muscle anywhere in the body and at any age. Two other reported cases which were detected by prenatal ultrasound examination are also discussed.  (+info)

Orbital lymphangioma: an analysis of 26 patients. (3/350)

AIM: To evaluate retrospective data on the clinical findings, histological features, radiological diagnosis, and management outcomes in orbital lymphangioma. METHODS: Data on 26 orbital lymphangioma patients managed over 16 years were re-evaluated. The computed tomograph and magnetic resonance scans and histological slides were reviewed. Parametric techniques were used to assess correlations among clinical, radiological, and histopathological factors. RESULTS: At presentation proptosis was present in 85%, ptosis in 73%, and restrictive eye movements in 46% of patients. The accuracy of the initial radiology interpretations was 77%. 24 cases required one or more surgeries. The mean follow up was 9.2 years (range 1-14 years). 58% of patients developed recurrences. In cases that recurred, motility restriction was significantly more frequent at initial examination than cases without recurrence (p < 0.05). After therapy, 75% of patients were satisfied with their visual function and cosmetic appearance. CONCLUSIONS: Conservative management of orbital lymphangioma with multiple partial resections may achieve satisfactory results.  (+info)

Cavernous hemangiomas of the orbit: MR imaging. (4/350)

PURPOSE: To describe the MR imaging findings in eight patients with cavernous hemangioma of the orbit. METHODS: CT, MR imaging and echographic studies of eight patients with cavernous hemangioma localized in the orbit were reviewed. All patients presented with a progressive symptomatology: in seven cases with a painless proptosis, in one case with a failing of visual acuity of the concerned eye. The patients were examined with T2- and T1-weighted spin echo sequences, before and after intravenous administration of Gadolinium*, in axial, coronal and sagittal planes. In seven patients, a fat saturation prepulse was given after the Gd-enhanced study. Two patients were also examined with CT scan, with and without intravenous contrast administration. Three patients underwent a Doppler color-coded transorbital sonography. The analyzed criteria were: location, form, margins, size, signal or density. Seven patients underwent surgery with pathologically proved cavernous hemangioma. In one patient, therapy was conservative, because of the absence of significant clinical complaints. RESULTS: In all cases, MRI showed a well-defined intraconal mass. The lesions were homogeneous, isointense to muscle on the T1-weighted sequence and hyperintense to muscle on the T2-weighted sequences. In five cases, a peripheral rim, hypointense to the mass on the T1- and T2-weighted sequences could be observed. After Gadolinium*, six lesions showed initial central patchy enhancement. On the three following T1-Gadolinium* sequences, these lesions showed total and homogeneous filling. In two patients, the lesions showed immediate homogeneous enhancement. On CT, the orbital masses were spontaneously hyperdense, with associated focus of microcalcifications. On echography, the lesions appeared hyperechogenic, heterogeneous, with individualization of small areas of very slow flow. CONCLUSION: From the analysis of the MR appearance of an intraconal, well-defined mass, associating homogeneous signal, isointense to muscle on T1-weighted sequence, hyperintense on T2-weighted sequence, and especially progressive filling on Gd-enhanced sequences, the diagnosis of cavernous hemangioma may be highly suggestive, in a patient presenting a painless progressive proptosis.  (+info)

Phase II window of idarubicin in children with extraocular retinoblastoma. (5/350)

PURPOSE: The aim of this study was to evaluate in an upfront phase II study the response to idarubicin in children with extraocular retinoblastoma. PATIENTS AND METHODS: The starting dose of idarubicin was 15 mg/m(2)/d (days 1 and 2) weeks 0 and 3. After an interim evaluation, the dose was reduced to 10 mg/m(2)/d (days 1 and 2) weeks 0 and 3 because of hematopoietic toxicity. Response was evaluated at week 6. RESULTS: At the Hospital JP Garrahan (Buenos Aires, Argentina), 10 patients (five bilateral) were entered onto the study from 1995 to 1998. A total of 19 cycles were administered. Extraocular sites included orbit (n = 10), bone marrow (n = 3), bone (n = 1), lymph node (n = 1), and CNS (n = 1). The response rate was 60% (95% confidence interval, 30% to 90%). One complete response was achieved, in addition to five partial responses, two cases of stable disease, and two cases of progressive disease. All patients with bone marrow involvement achieved complete clearance of tumor cells. The patient with CNS disease had progressive disease. All patients had severe hematopoietic toxicity (grade 4 neutropenia and grade 3/4 thrombocytopenia after most cycles). Other toxicities included grade 2 diarrhea in 30%. No echocardiographic changes were detected. CONCLUSION: Idarubicin is active in extraocular retinoblastoma. The activity of this drug should be explored in future phase III studies.  (+info)

Combined fat- and water-suppressed MR imaging of orbital tumors. (6/350)

BACKGROUND AND PURPOSE: The use of a high-resolution T2-weighted MR sequence, which suppresses signal from both fat and water, has been shown to be highly effective for depicting areas of inflammatory damage within the optic nerve. The ability of this sequence to show neoplastic and inflammatory orbital lesions, which may mimic neuritis, is unknown. This study was designed to examine the characteristics of such a sequence for the investigation of orbital mass lesions. METHODS: Twenty-eight patients with known or suspected mass lesions of the orbit and six healthy volunteers were recruited for study. Imaging was performed with a 1.5-T MR unit. Participants were examined by selective partial inversion recovery (SPIR) sequences with T2-weighted fast spin-echo acquisition, selective partial inversion recovery/fluid attenuated inversion recovery (SPIR/FLAIR) sequences with fast spin-echo acquisition, short tau inversion recovery (STIR) sequences with fast spin-echo acquisition, and SPIR sequences with contrast-enhanced T1-weighted fast spin-echo acquisition. Two neuroradiologists, using a randomised, blinded method, scored images for lesion presence and extent. Lesion extent was defined as the number of images with visible abnormality, and was compared with the standard of reference established at a later date by consensus review of all imaging sequences. The ability of the sequences to show the presence and extent of pathologic lesions was compared. RESULTS: The SPIR/FLAIR sequence showed both the presence and extent of orbital masses significantly better than did either STIR or T2-weighted SPIR sequences (P<.01 and P<.001, respectively). Contrast-enhanced T1-weighted SPIR images ranked better than SPIR/FLAIR images, although the difference failed to reach statistical significance. In the orbital apex, the SPIR/FLAIR technique was superior to all other techniques used. This reflected its ability to distinguish enhancing, pathologic lesions from enhancing, normal anatomy. CONCLUSION: SPIR/FLAIR is an appropriate screening technique for orbital masses and offers significant advantages over currently used fat-suppressed sequences for the investigation of orbital disease.  (+info)

Recurrent proptotic diplopia due to congestive expansion of cavernous haemangioma with relapsing right-sided cardiac failure. (7/350)

A 75-year-old man with a recent history of pulmonary embolism, presented with collapse followed by a gran mal seizure and right-sided non-pulsatile proptosis. On recovery, he had diplopia on lateral and upward gaze and signs of congestive cardiac failure. Further pulmonary embolism was proven by lung scintigraphy. Computed tomography of his orbits confirmed a contrast-enhancing space-occupying lesion of the medial wall of the right orbit, with no intracranial abnormality. The patient was investigated for metastatic tumour as a possible cause of the space-occupying lesion and the unprovoked thromboembolic event, but no evidence of malignancy was found. The orbital lesion was not biopsied because of the risk of bleeding from anticoagulation. Three weeks later, the patient represented with recurrent cardiac failure, proptosis, and diplopia. A transorbital ultrasound confirmed an encapsulated, well-defined vascular lesion, with typical appearances and Doppler flow characteristics of a cavernous haemangioma. Diuretic therapy abolished the proptosis and diplopia in tandem with relief of the cardiac failure. This is the first description of recurrent proptosis with diplopia due to recurrent congestive expansion of an orbital cavernous haemangioma.  (+info)

Bilateral Orbital Metastasis of Follicular Thyroid Carcinoma: a Rare Case ReportBilateral Orbital Metastasis of Follicular Thyroid Carcinoma: a Rare Case Report
Follicular thyroid carcinoma (FTC) is the second most common type of thyroid cancer after papillary carcinoma. It usually grows slowly and is clinically indolent; but rarely, its aggressive forms with distant metastases can occur. We report here an uncommon case of bilateral orbital metastasis of FTC. A 70-year-old woman presented with bilateral exophtalmus and past medical history of thyroid nodule surgery 15 years ago. Radiologic evaluation showed massive bilateral orbital mass with extension to calvarium. Tumor decompressed and removed with the suction and curettage and the patient was treated with chemoradiotherapy after operation. Pathologic examination showed metastatic follicular thyroid carcinoma. Although orbital metastasis of follicular thyroid carcinoma is uncommon, FTC should be considered as a potential primary neoplasm in a patient with orbital mass

Orbital Rhabdomyosarcoma with a good life prognosis after surgical treatment in a 14-year-old patient - Open Medicine - Volume...
The orbital rhabdomyosarcoma is one of the most frequent malignant orbital tumours in children. At this age, the common histological types are the embryonal and alveolar type. The onset is mainly under the age of 16. Without a recent and correct treatment it can give metastasis in lung and bone. The hereby paper presents one clinical case of a teenager presented at the ophthalmological consultation for a small tumor located in the superomedial part of the orbit. Computed tomography (CT) and magnetic resonance imaging (MRI) supported the diagnosis revealing the location and extension of the tumor. During the surgery, we discovered two small tumors and the histological examination revealed an embryonal type of orbital rhabdomyosarcoma. After the surgery, the patient followed an oncological treatment consisting of chemotherapy and local radiotherapy. The prognosis for life was favorable, linked with the recent diagnosis and treatment, the histological type and the good response at the oncological ...

Pictorial Review of Histopathologically Diagnosed Orbital Tumors - American Journal of Ophthalmic Clinical TrialsPictorial Review of Histopathologically Diagnosed Orbital Tumors - American Journal of Ophthalmic Clinical Trials
A systemic radiological approach to examining the images is needed to reach a differential diagnosis. The images should be studied for lesion appearance, localization, contrast enhancement, bony orbit evaluation, and detection of calcifications.[3,4]. The lesion appearance on imaging includes; solid or cystic, well circumscribed or ill-defined, and localized or infiltrative.[4] Comparing the density of the lesion with that of the vitreous body can help to identify a solid lesion, whose density is higher than that of vitreous on CT images.[4]. Orbital tumors can be localized anatomically to within the globe/intraocular or intraconal or in the extraconal space, the orbital apex, the extraocular muscles, or the lacrimal gland. CT remains the modality of choice for evaluation of the bony orbit and paranasal sinuses. MRI is preferred to evaluate the optic nerve and chiasm.[3,4]. Contrast enhancement aids in the characterization of orbital masses. Moderate to marked enhancement is usually noted in ...

Comparative evaluation of orbital lesions by ultrasonography and computed tomography | International Journal of Current Research
Introduction: Ultrasonography has proved its accuracy in orbital imaging by virtue of its high frequency probes and b mode imaging. The CT extends privilege of perfect anatomical images and better delineation using intravenous contrast. The current study evaluated clinical and radiological presentation of various orbital lesions; and compared diagnostic accuracy of USG and CT. Material and methods: A prospective observational study was planned at a tertiary teaching institute on 100 patients referred to radiology department for ultrasonography and computed tomography of orbit. Patients with lesions arising primarily from orbit or spread from adjacent structures were included in the study. Observations: Majority of patients were pediatric; common etiology being retinoblastoma and infection. The central orbital space was most predisposed in inflammatory and vascular lesions: and, peripheral orbital space in neoplastic, trauma, congenital, lacrimal gland and fossa lesions. The diagnostic ...

halo orbit
A halo orbit is a type of orbit around an L1, L2, or L3 Lagrangian point. It is periodic, in that it follows same path each cycle other than the slow degradation due to the points instability (which can be handled by stationkeeping). Such orbits can allow a line of sight around the body in the middle, such as an orbit beyond the Moon that always has a line of sight to stations on Earth. They also help allow multiple spacecraft to operate at (near) the same point, such as all the spacecraft at Earth-Sun L1 and L2. Two other kinds of orbits are possible for use at the L1-L3 points: a Lissajous orbit, which is not periodic in the same sense. With each cycle, the path is different, but I believe they remain in a cylinder-like thin curved volume. Lissajous orbits are now more commonly used than halo orbits. A Lyapunov orbit is also aperiodic, but remains in a plane. I suspect halo orbits and Lyapunov orbits can be looked at as special cases of Lissajous orbits, but I havent seen this stated. ...

Mass over the eyelidMass over the eyelid
Management of any orbital tumor depends upon whether it is likely to be benign or cancerous. Well-localized benign tumors are often removed completely, using minimally invasive techniques via hidden incisions. Though orbital tumors can also be removed by a neurosurgeon via a brain-surgery approach, it is far less invasive to get it done from an orbital surgeon. Histopathological confirmation is the best way to ensure complete removal and to know the exact diagnosis. Reconstruction of the orbit after removal of the mass is dependent on the size and location of the defect. Various reconstruction options are available ...

The OP is inherently a less accurate plane to measure on account of the lack of precise landmarks. Zollikofer et al. (2005) and Brunet and Allemand (2005) did not provide details of how they measured the orientation of the OP, but judging from the illustrations it was obtained by drawing a vertical line in the middle of the orbit extending from the anterodorsal margin of the orbit to the antero-ventral edge of the orbit immediately beneath the former point. There are four main difficulties with this measurement, the first being that the left and right sides of the same skull may be different (in fact each orbit has its own OP). The second, and a more serious difficulty is that the upper and lower margins of the orbits are curved dorsoventrally (strongly) and mediolaterally (gently), and thus it is difficult to define precise points for consistent measurements between individuals or successive measurements in the same individual, and thus of obtaining reliable results for the orientation of the ...

The Orbit and Ear
Once the structures in the orbit are learned, you should then try to understand how the muscles act on the eye to move it. This knowledge is necessary in clinical situations when you examine the eye during a full physical examination or after head injuries. In order to fully understand the movements of the eyeball you should realize that the eyeball moves around three axes: (1) vertical, (2) horizontal and (3) anteroposterior. Movements around the vertical axis are abduction and adduction, around the horizontal axis, elevation and depression and around the anteroposterior axis, medial and lateral rotation. This last movement usually requires the use of special equipment to see it, so we wont consider it at this time ...

Virgin Orbits LauncherOne meets Cosmic Girl 747 | VirginVirgin Orbits LauncherOne meets Cosmic Girl 747 | Virgin
To add some context, heres a few quick facts about LauncherOne. At 70 feet, it is twice the length of a London bus and will travel at more than 20 times the speed of sound. The rocket weighs 57,000 pounds, which is the equivalent to 25 small family cars. Launcher Ones payload will carry satellites that could be as small as a loaf of bread and as large as a household fridge. Cosmic Girl is the first 747 in history that has been converted to launch rockets. This means it can fly thousands of miles in any direction at 24 hours notice to deliver to the right orbit. Currently, people have to wait between 18 and 24 months for manufacturing and a ground launch.. A week earlier, I got to visit the team at our home in Long Beach and see the progress taking place first-hand. I also got to take a sneak peek inside Cosmic Girl too. It was amazing seeing the modified 747 looking so different from her days as part of our Virgin Atlantic fleet. Its the ultimate upcycling!. ...

Branches of periodic orbits for the planar restricted 3-body problemBranches of periodic orbits for the planar restricted 3-body problem
We describe a method for studying the existence and the linear stability of branches of periodic solutions for a dynamical system with a parameter. We apply the method to the planar restricted 3-body problem extending the results of [A]. More precisely, we prove the existence of some continuous branches of periodic orbits with the energy or the masses of the primaries as parameters, and provide an approximation of the orbits with rigorous bounds. We prove the linear stability or instability of the orbits.

Orbit itself does not have releases, per se, since the 3rd party jars that are bundled have already been released. But, we will still use the Eclipse Simultaneous Release rhythm to set deadlines for ourselves and promote and retain bundles. An Orbit milestone will be considered the same as the base Eclipse platform. This is a statement of time, as opposed to content, since for anyone else in the Simultaneous Release to use an Orbit Bundle, it would have to be ready (and final) at least a week or two before their milestone deadline. Our continuous builds produce bundles (builds) in the committers area. Their purpose is for the committers to have something to see or download and confirm all is as they expect it to be. These builds are often short lived and can be deleted without notice. Once per week, currently by Monday noon (Eastern time), the latest continuous build will be copied over to the downloads area. These are similar or analogous to weekly Integration Builds, and will be retained in ...

Interesting orbital diseases, besides tumors, include malformations and inflammatory, traumatic, degenerative and dysthyroid diseases, whose incidence depends on factors such as genetic predisposition, sex, race and, especially, age. The two leading diseases in terms of incidence are inflammatory forms and cysts, while dysthyroid orbital disease ranks third, followed by vascular malformations, which rank first for prevalence in adolescents. Traumatisms come fifth, followed by tumors in the sixth place. Until the age of 20, hemangioma is the most frequent orbital disease that alone is the fourth overall cause in terms of incidence. In the 20-60 years of age group the disease is dominated by dysthyroid orbital disease (ca 60% of cases), followed by tumors. In patients aged over 60, dysthyroid orbital disease rank first for incidence, almost at the same level with tumors. Often orbital tumors are rather hard to diagnose as the clinical events triggered by both neoplastic and non-neoplastic diseases ...

The marginal zone (MZ) was originally defined as an anatomical compartment within the spleen located around primary or secondary follicles and containing B cells with distinct phenotypic and functional characteristics. The MZ of the spleen is believed to be positioned in such a way that it primarily encounters blood borne pathogens. Later, primary mucosa-associated lymphoid tissues (MALT) of e.g. Waldeyers ring, Peyers patches and appendix, locations known for a significant influx of Ags, were also found to contain a marginal zone. MZ B cells in mice and rats express essentially unmutated IgV genes and are supposed to be non-recirculating.29 On the other hand, human MZ B cells of both spleen and Peyers patches do harbor mutated IgV genes and recirculate (Figure 2).30-32 Human splenic MZ B cells are IgM IgD and co-express the B-cell markers CD20, CD22 and CD79a/b, the memory B-cell marker CD27, the complement receptors CD18/CD11b, CD21 and CD35, and the anti-apoptotic molecule BCL-2.

Imaging an Orbital Mass: The EssentialImaging an Orbital Mass: The Essential
Looking for or discovering an orbital mass may raise many questions. To provide at least partial answers, we will target the most frequent pathologies encountered and propose for each of them a practical presentation including specific clinical tips, imaging protocol and characteristic features. The lesion may be disclosed during a brain Computed Tomography (CT) or Magnetic Resonance Imaging (MRI), or alternatively looked for because it causes symptoms such as exophthalmos and visual or oculomotor alteration. Imaging plays a major part in etiological diagnosis and patient management. If MRI remains the principal imaging method, CT scan and ultrasound (US) with Colour Doppler flow imaging (CDFI) may be very helpful. These different imaging techniques may be associated, depending on the lesion. The orbital MRI protocol performed in our institution includes the following sequences: thin (3 mm) axial T1-weighted, coronal T2-weighted or T2-weighted Dixon, axial diffusion-weighted, then after contrast ...

Magnetic Resonance Imaging in Orbital Pathologies: A Pictorial ReviewMagnetic Resonance Imaging in Orbital Pathologies: A Pictorial Review
Orbital lesions form a wide range of pathologies that pose challenges in diagnosis, management and treatment. The soft tissue detail provided by magnetic resonance imaging (MRI) allows for better lesion characterization. MRI therefore plays a crucial role, especially in cases where history and clinical evaluation are inconclusive [1]. There are several approaches for the correct diagnosis of orbital pathology. A common diagnostic strategy is the localization of the pathology into the four main orbital compartments [2]: the ocular compartment or globe, the muscle cone and the intraconal and extraconal spaces (Figure 1). The muscle cone contains recti muscles and their fasciae; on its base, the globe is present, and the optic canal figures the apex. The globe is encircled by the Tenons capsule, which has three layers: the sclera, uvea and retina. The extraconal space includes the superior and inferior oblique muscles, levator muscle complex, the lacrimal gland and the orbital fat. The aim of this ...

E-mail: [email protected] Following a complete preoperative study that did not contraindicate surgery, a decision was taken to operate the patient with general anesthesia using a bicoronal approach from the ipsilateral preauricular region to the contralateral preauricular region, separating the skin mass underneath the subperiosteal and temporal fascia and starting from the zygomatic arch and frontal eminence. An approach was made through the entire external rim of the right orbit and right malar area, together with an osteotomy of the malar bone (lateral orbitotomy). The periorbit was then incised and an intraconal approach was made to the lesion, which had the appearance of a hemangioma and was well defined. It was resected and the surrounding tissue pulled away. The reconstruction of the zygomatic arch and the frontal eminence was carried out with flat miniplates.. The macroscopic examination of the histologic study showed a nodular formation with a diameter of 2.5 cm, which was well ...

To report the clinical experience of eye sparing surgery (ESS) and adjuvant carbon-ion or proton radiotherapy (CIRT or PRT) for orbital malignancies. An analysis of the retrospective data registry from the Shanghai Proton and Heavy Ion Center for patients with orbital tumors was conducted. The 2-year local progression-free, regional recurrence-free, distant metastasis-free, progression-free, and overall survival (LPFS, RRFS, DMFS, PFS, OS) rates as well as associated prognostic indicators were analyzed. Radiotherapy-induced acute and late toxicities were summarized. Between 7/2014 to 5/2018, 22 patients with orbital malignancies of various pathologies received ESS followed by CIRT (18), PRT (1), or PRT + CIRT boost (3). With a median follow-up of 20.25 (range 3.8-38.8) months, the 2-year OS, PFS, LPFS, RRFS, and DMFS rates were 100, 57.9, 92.9, 93.3, and 72.8%, respectively. No acute severe (i.e., ≥grade 3) toxicity was observed. Two patients experienced severe visual impairment as late toxicities.

Eccentricity of an Orbit - Windows to the UniverseEccentricity of an Orbit - Windows to the Universe
You may think that most objects in space that orbit something else move in circles, but that isnt the case. Although some objects follow circular orbits, most orbits are shaped more like stretched out circles or ovals. Mathematicians and astronomers call this oval shape an ellipse.. An ellipse can be very long and thin, or it can be quite round - almost like a circle. Scientists use a special term, eccentricity, to describe how round or how stretched out an ellipse is. If the eccentricity of an ellipse is close to one (like 0.8 or 0.9), the ellipse is long and skinny. If the eccentricity is close to zero, the ellipse is more like a circle.. The eccentricity of Earths orbit is very small, so Earths orbit is nearly circular. Earths orbital eccentricity is less than 0.02. The orbit of Pluto is the most eccentric of any planet in our Solar System. Plutos orbital eccentricity is almost 0.25. Many comets have extremely eccentric orbits. Halleys Comet, for instance, has an orbital ...

The effect of orbit plane precession is used to place a plurality of satellites into one or more desired orbit planes. The satellites are distributed within each desired orbit plane in a selected configuration. The satellites are transported into orbit on one or more frame structures referred to as pallets. When more than one pallet is used, they are placed on top of each other in a stack. After the stack of the pallets has been launched into an initial, elliptical orbit, the pallets are separated sequentially from the stack at selected time intervals. Thrust is applied to transfer a first pallet from the initial orbit to a first, circular orbit, wherein the initial and first orbits are in planes that process at different predetermined initial and first rates, respectively. After waiting for a predetermined time while the initial orbit plane and the first orbit plane precess with respect to each other, thrust is applied to the next pallet to transfer it into a next, circular orbit in a next orbit

Hybridisation - Mixing Up Orbitals with sp, sp2, sp3 | Biochem.co - Biochem & Science NotesHybridisation - Mixing Up Orbitals with sp, sp2, sp3 | Biochem.co - Biochem & Science Notes
Only 2 of the 2p orbitals are used in sp2 hybridisation; in contrast to the 3 used in sp3 hybridisation (you should be seeing where the numbers come from!).. This leaves us with 3 sp3-orbitals and 1 p-orbital to bond with. 2 of the sp3 orbitals are used for forming σ-bonds with the 2 hydrogens, while the remaining sp3 orbital binds with the other carbon to form a σ-bond and the p-orbital bonds with a p-orbital from the other carbon to form a π-bond.. Every double bond (regardless of what atoms it joins) consists of a π-bond and a σ-bond.. ...

Chemistry: Covalent Compounds Get MysteriousChemistry: Covalent Compounds Get Mysterious
None of what youve learned so far is wrong. However, your understanding of bonding in covalent compounds isnt yet complete. Specifically, while we know that electrons are shared between two atoms in a covalent molecule, we dont have any ideas about the locations of these electrons. As you might imagine, theyre located within orbitals, but what sort of orbitals exist between two atoms?. Why are orbitals important? As it turns out, covalent bonds are formed when two orbitals from different atoms, each of which have one electron in them, overlap so that these two electrons are shared. Because these orbitals need to overlap for a bond to be formed, its important that we understand the shapes of orbitals that are formed in covalent compounds.. Before we can fully understand the true nature of orbitals in covalent compounds, we must see whats incomplete about our current understanding of orbitals and electrons. Imagine CH4. The type of diagram we saw in Getting to Know Covalent Compounds makes ...

Orbits are presented for four ninth-magnitude stars about which the only spectroscopic datum previously known is the HD type, K0 in each case. The most interesting of the four stars is perhaps HD 145677, whose lack of proper motion suggests a high luminosity, which is hardly compatible with the shortness (4.4 days) of its orbital period.

Sixth Orbit Catalog, Calibration Candidates
A few words of warning are in order! First, all calibration candidate orbits are NOT of the same quality, however much we would like them to be! Before using a set of elements please examine the elements, figures, etc. carefully to check whether that orbit appears to be of proper scale and sufficient quality for your purposes. Also, using measurements of double stars to calibrate the measurement of other double stars is certainly circular (or, if you will, Keplerian). We strongly advocate the use of other absolute calibration techniques such as a slit mask (cf, McAlister et al. 1987, AJ, 93, 688; Hartkopf et al. 1997, AJ, 114, 1639; or Douglass et al. 1997, ApJS, 111, 289) or at least star trails (for east-west orientation) if at all possible. When double stars are necessary for scale calibration, the set provided should be adequate; however, the measures you determine will only be as accurate as the calibration systems you use. The use of these systems for identification of higher-order ...

Examples: Satellite television broadcasting, weather and reconnaissance satellites.. A geosynchronous orbit is one that is in sync with the rotation of Earth: it takes geosynchronous satellites exactly one day to complete one orbit. If a geosynchronous satellite is placed in the same plane as the equator then that satellite is said to be geostationary - relative to an observer on Earth it remains in the same place in the sky all the time. This means that the antennae used to communicate with geostationary satellites can remain in a fixed position - they do not have to move to track the satellite as it moves across the sky.. The idea of a geostationary satellite was popularised by the science fiction author Arthur C. Clarke in an article for Wireless World magazine entitled Extra-Terrestrial Relays - Can Rocket Stations Give World-wide Radio Coverage? so geostationary orbits are sometimes known as Clarke Orbits.. Calculating the height of a geostationary orbit is relatively simple. Any object ...

Elliptic orbit - WikipediaElliptic orbit - Wikipedia
The state of an orbiting body at any given time is defined by the orbiting bodys position and velocity with respect to the central body, which can be represented by the three-dimensional Cartesian coordinates (position of the orbiting body represented by x, y, and z) and the similar Cartesian components of the orbiting bodys velocity. This set of six variables, together with time, are called the orbital state vectors. Given the masses of the two bodies they determine the full orbit. The two most general cases with these 6 degrees of freedom are the elliptic and the hyperbolic orbit. Special cases with fewer degrees of freedom are the circular and parabolic orbit. Because at least six variables are absolutely required to completely represent an elliptic orbit with this set of parameters, then six variables are required to represent an orbit with any set of parameters. Another set of six parameters that are commonly used are the orbital elements. ...

Geostationary Orbit, 978-613-3-86154-1, Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A geostationary orbit is a geosynchronous orbit directly above the Earths equator, with a period equal to the Earths rotational period and an orbital eccentricity of approximately zero. These characteristics are required so that, from locations on the surface of the Earth, geostationary objects appear motionless in the sky, making the GEO an orbit of great interest to operators of communications and weather satellites. Due to the constant 0° latitude and circularity of geostationary orbits, satellites in GEO differ in location by longitude only. The notion of a geosynchronous satellite for communication purposes was first published in 1928 by Herman Potodnik. The idea of a geostationary orbit was first published on a wide scale in a paper entitled Extra-Terrestrial Relays - Can Rocket Stations Give Worldwide Radio Coverage? by Arthur

Orbit OculoplastyOrbit Oculoplasty
What is Orbit & Oculoplasty? Orbit refers to the eye-socket (the cavity in the skull that holds the eye) and the surrounding structures. Diseases of the Orbit may arise from within the eye-socket or might be a secondary condition arising out of an existing illness. While some of these issues could be cosmetic, quite a few of orbital problems might affect the regular functioning of the eyes. Theres sure relief for these conditions and oculoplasty is a cosmetic/reconstructive surgical procedure that comes to the rescue of patients with eye orbit problems. Orbit - Things that cant be overlooked Its quite natural to admire those almond-shaped eyes of your child for hours. However, not all people in the world are lucky to have those perfectly shaped eyes. Some of us may have problems like drooping eyelids, protruding eyes, inturned eyelashes, etc. Earlier, people would have to live with these malformations.

  • The top 3 pediatric orbital tumors are dermoid cysts, capillary hemangiomas, and rhabdomyosarcoma. (medscape.com)
  • The top 3 adult orbital tumors are lymphoid tumors, cavernous hemangiomas, and meningiomas. (medscape.com)
  • Capillary hemangiomas are the most common orbital tumors found in children. (medscape.com)
  • Other benign orbital lesions include dermoids, lymphangiomas, and histiocytic tumors. (medscape.com)
  • Rarely, late presentation with large orbital tumors and diffuse involvement is seen [2]. (peertechzpublications.com)
  • Radiation therapy: orbital tumors. (rush.edu)
  • Optic nerve meningiomas are benign tumors arising from the arachnoid cap cells of the optic nerve sheath and represent ~20% of all orbital meningiomas , the majority of which are direct extensions from intracranial meningiomas . (radiopaedia.org)
Lesions7
  • None had isolated dacryoadenitis but in 17 eyes dacryodenitis was described in association with other types of orbital lesions. (haematologica.org)
  • retro-orbital, thyroid and oral-pharyngeal masses or lesions encompass a wide range of benign and malignant processes other than lymphoma. (medscape.com)
  • Since the orbit is a relatively small anatomical area with little wasted space, space-occupying lesions that increase orbital volume may result in proptosis of the globe and may adversely affect visual and extraocular muscle function. (medscape.com)
  • Neuroblastomas, Ewing sarcoma, Wilms tumor, and leukemias are the more common metastatic orbital lesions afflicting children. (medscape.com)
  • Superior Orbital Fissure vs Cavernous Sinus vs Orbital Apex Lesions. (medscape.com)
  • Orbital and intraocular choristomas are the most harmful lesions as orbital choristomas are frequently associated with permanent diplopia while intraocular lacrimal gland choristomas have a poor visual prognosis and are a common cause of enucleation of the eye. (aboonline.org.br)
  • CT is excellent at evaluating the bony anatomy, orbital fat, bony cortex, and for depicting the internal architecture of some fibro-osseous (see Fig. 1 ) and other bony lesions (see Fig. 2 ). (radiologykey.com)
Malignant6
  • Primary orbital tumefaction, although quite rare, encompasses a lexicon of benign and malignant neoplasia. (medscape.com)
  • Rhabdomyosarcoma, a mesenchymal tumor, is the most common primary malignant orbital tumefaction in children. (medscape.com)
  • Although a mass may be histologically benign, it can encroach on intraorbital or adjacent orbital structures and be considered anatomically or positionally malignant. (medscape.com)
  • Although it is the most frequently seen malignant neoplasm of the conjunctival epithelium, the literature suggests that it normally behaves in a nonaggressive fashion [5]. (peertechzpublications.com)
  • Malignant tumor of maxillary sinus is an uncommon neoplasm. (e-roj.org)
  • Importantly, however, the patients' symptoms may occasionally have other causes, such as a more aggressive inflammatory process or a malignant neoplasm. (radiologykey.com)
Proptosis2
  • The globe may be nonaxially displaced away by an orbital mass, whereas an axial proptosis suggests a mass within the muscle cone of the orbit. (obgynkey.com)
  • Prominence of the globe can occur with high myopia, buphthalmos, proptosis (orbital mass or idiopathic), craniosynostosis, orbital floor fractures (upper lid retracted from traction on connective tissue sheath), and as a postoperative finding from scleral buckle surgery, blepharoplasty, orbicularis myectomy, and glaucoma filtering operation with prominent bleb.
