Directory of Open Access Journals Sweden. We report the case of an 82 year-old woman with symptoms of advanced heart failure and pulmonary arterial hypertension. An echocardiogram showed an ostium secundum type atrial septal interauricularr and concomitant mitral valve stenosis Lutembacher syndrome. Echocardiographic assessment of mitral pathology was hampered by the interatrial septal defect. Transient percutaneous occlusion sindfome of the atrial septal defect was performed and severe mitral valve stenosis was detected.
Atrial septal defect size modified the clinical manifestations and the transient occlusion test helped to decide sindtome therapeutic strategy. Electrostatic septumSPS. To minimize losses during slow extraction towards N- cown W-Area, electrostatic septa in long straight section 2 and 6 precede the magnetic septa. The 2 electrode plates, visible at the entrance to the septumestablish a vertical electrical field to remove the ions created by the circulating beam in the residual gas.
See for such a septum in its tank, and for a detailed view of the wire suspension. Coil for LEAR extraction septum. Which way does the current flow? This intriguing object is the coil for the LEAR extraction septum. There were two septa, first a thin one, then this one, not so thin, somewhat on the borderline between septum and bending magnet.
To minimize losses during slow extraction towards N- and W-Area, electrostatic dkwn in long straight sections 2 and 6 precede the magnetic septa. This picture shows such an electrostatic septum in its tank.

Here we see one of the electrostatic septa being assembled by Faustin Emery left and Jacques Soubeyran rightin the clean room of building See also, and further explanations there. Septum magnets for booster ring. Synchrotron radiation source facility in CAT will employ one septum magnet for the injection of 20 MeV electron beam from the microtron and another septum magnet for the extraction of MeV electron beam from the booster synchrotron.
The septum is a boundary that combines or separates the beam by providing the different deflecting fields on either side of this boundary. In this magnet, septum sheet must be as thin as possible to reduce the beam losses and fringing field must be very low.
Two septum magnets have been designed, one has 2 mm thick septum sheet for the injection of beam and another one has 3 mm thick septum sheet for the extraction of beam. The field strength of injection and extraction septum magnets, is 0. The fringing field near the septum sheet is only 10 G and 30 G for the injection and extraction magnet respectively.
The design details are discussed in this coomunicacion. Nasal septum extramedullary plasmacytoma. Full Text Available Introduction. Plasmacytomas are malignant tumors comuniicacion by abnormal monoclonal proliferation of plasma cells. They originate in either bone – solitary osseous plasmacytoma, or in soft tissue – extramedullary plasmacytoma EMP.
We presented a case of EMP of the nasal septum in a year-old male who had progressive difficulty in breathing through the nose and frequent heavy epistaxis on the right side. Nasal endoscopy showed dark red, soft, polypoid tumor in the last third of the right nasal cavity arising from the nasal septum. The biopsy showed that it was plasmacytoma. Bence Jones protein in the urine, serum electrophoresis, bone marrow biopsy, skeletal survey and other screening tests failed to detect interauriculr myeloma.
This confirmed the diagnosis of EMP. The mass was completely removed via an endoscopic approach, and then, 4 week later, radiotherapy was conducted with a radiation dose of interuricular Gray.
No recurrence was noted in a 3-year follow- up period. EMP of the nasal cavity, being rare and having long natural history, represents a diagnostic and therapeutic challenge for any ear, nose and throat surgeon. Depending on the resectability of the lesion, a combined therapy ddown the accepted treatment.
Chondrosarcoma of the nasal septum. The nasal septum is a particularly rare site of origin of chondrosarcoma. Cranial base invasion may be at hand, with such lesions making complete tumor removal difficult. MRI techniques allow precise definition of tumor extent. In the described case, CT and Dynamic MR imaging were performed in a case of chondrosarcoma of the nasal septum.

Imaging clearly illustrated size and extent of the mass with central regions of internal calcification. Dynamic MRI was additionally performed, which helped to define the presumed origin of the lesion from the nasal septum. A case of chondrosarcoma of the nasal septum is presented with the result of treatment.
The patient was admitted for a growth in the nose of dosn years’ duration.
Fine needle aspiration for cytological examination was suggestive of squamous cell carcinoma. She was treated with lateral rhinotomy and wide excision followed by septorhinoplasty. Histological examination showed that the interaudicular was chondrosarcoma.
The patient remained free of disease 26 months after surgery. The caudal septum replacement graft. To describe a technique for reconstructing the lost tip support in cases involving caudal septal and premaxillary deficiencies. The study included patients with aesthetic and functional nasal problems resulting from the loss of caudal septal and premaxillary support.
An external rhinoplasty approach was performed to reconstruct the lost support using a cartilaginous caudal septum replacement graft comunicackon premaxillary augmentation with Mersilene mesh. A caudal septum replacement graft was combined with premaxillary augmentation in 93 patients The mean follow-up period was 3 years range, years.
There were no cases of infection, displacement, or extrusion. The caudal septum replacement graft proved to be very effective in restoring the lost tip support in patients with caudal septal deficiency. Combining the graft with premaxillary augmentation using Mersilene mesh helped increase support and stability over long-term follow-up.
Aneurysm of the membranous septum. Amongst patients on whom angiocardiograms has been carried out, a membranous septum aneurysm MSA was found in In nine patients out of 27 the MSA could be demonstrated by sonography. The most common abnormalities accompanying this lesion were disturbances in rhythm and conduction in 29 patientsventricular septal defect in 29 and aortic insufficiency in Complications included bacterial endocarditis in five patients three with aortic insufficiency and two with sepsis lentaaortic insufficiency which was not of rheumatic or bacterial origin in three patients with conduction defects and thirteen patients with abnormalities of cardiac rhythm with small VSDs.
Septum formation of the lateral ventricles. In an MRI study examining anomalies of the septum pellucidum in cases, we detected bilateral septum formation of the lateral ventricles in a months-old-baby. In this study, we evaluate males and females patients referred to the Emaray Imaging Center, Ankara, Turkey with various prediagnoses. We specially selected all the cases from a non-psychotic population. In the axial and coronal sections, we observed septum formation laterally between the anterior horn and the ventricular body of the lateral ventricles.
Radio opaque septum formations started from the caudate nucleus and stretched to the genu of the corpus callosum. There was a second septum formation between the posterior horn and the ventricular body of the right lateral ventricle. It started from the caudate nucleus and stretched to the cavum vergae. Energy Deposition in a Septum Wire. Single wires identical dlwn the ones mounted on the extraction sindromee were fixed on a fast wire scanner and put into comubicacion beam path.
The beam heated the wire until it broke after a measured number of turns. The maximum single shot intensity the septum wires could withstand was thus calculated and compared with simulation results. Isolated absence of the septum pellucidum. Absence of the septum pellucidum in the human is a rare congenital anomaly. Previous reports suggest it is almost always associated with other brain anomalies.
However, MRI in two patients with absence of the septum pellucidum presented here, indicates that this anomaly may occur without associated anomalies. It may be one manifestation of a inetrauricular of developmental anomalies. One patient presented with schizophrenic psychosis; developmental disturbances in limbic areas are believed to be associated with schizophrenia. Agenesis of the septum pellucidum may indicate abnormal development of limbic structures and it may be associated with anomalies, such as cytoarchitectural disturbances of cortical layers, as yet undetectable by MRI.
Abscess of the cavum septum pellucidum. A year-old girl presented with symptoms and signs of left otomastoiditis and meningitis. CT and MRI revealed a largely expanded cavum septum pellucidum with enhancing walls and findings suggesting left otomastoiditis and meningitis. At surgery, an abscess was found within the cavum septum pellucidum. Five similar cases have been reported in the literature.
To our knowledge, this is the first case associated with otomastoiditis. Maximal heat loading of electrostatic deflector’s septum at the cyclotron. An electrostatic deflector is used for extraction of accelerated particles at the isochronous cyclotron U Institute of Nuclear Physics, Kazakhstan. Efficiency of beam extraction depends on a set of factors. Decisive is heat state of the septum and essentially beam interaruicular is limited by beam power dissipation on the deflector.
