objectives: new digital two-dimensional imaging systems are considered as an easily accessible modality for sinonasal evaluation. the aim of this study was to assess the diagnostic efficacy of digital waters’ and caldwell’s radiographic views for evaluation of sinonasal area. materials and methods: a total of 273 patients fulfilling the inclusion criteria were enrolled in this descriptive-analy...

Introdouction: The mapping of ghost images of the maxilla and the nasal cavity, which are complex structures, is very important. The position of objects that create a ghost image can differ when using various devices. The purpose of this investigation was to study the mapping of ghost images of the maxilla and the nasal cavity using a Cranex D digital panoramic machine. Materials and methods: ...

OBJECTIVE To determine whether regional hypoperfusion of the interventricular septum occurs during ventilation with positive end-expiratory pressure. DESIGN Animal study. ANIMALS Anesthetized, closed chest dogs (n = 8). INTERVENTIONS Induction of experimental adult respiratory distress syndrome (ARDS) and then ventilation with 10, 15, and 20 cm H2O of positive end-expiratory pressure. M...

During cytokinesis, fission yeast and other fungi and bacteria grow a septum that divides the cell in two. In fission yeast closure of the circular septum hole by the β-glucan synthases (Bgs) and other glucan synthases in the plasma membrane is tightly coupled to constriction of an actomyosin contractile ring attached to the membrane. It is unknown how septum growth is coordinated over scales o...

ume overload was created in open-chest dogs by pumping blood from the left atrium to the right atrium. In seven of eight dogs changes in interventricular septum motion were produced acutely at shunt flow as low as 500 cc/min. When the shunt was decreased or stopped, interventricular septum motion returned to normal. Shunts producing left ventricular volume overload (aorta to left atrium and rig...

Premenarchial Transverse vaginal septum is a benign condition. The septum may be found in the upper, middle or lower vagina. A case report of a premenarchial girl with transverse vaginal septum managed at the university college hospital, Ibadan, in January 2009. Diagnosis was made following a history of primary amenorrhea, cyclical low abdominal pain and pelvic examination which revealed a vagi...

a 47-year-old man presented as a dyspnea and fatigue. a transthoracic echocardi-ography (tte) performed to assess valvar heart disease and left ventricular (lv) function showed a large hydatid cysts in the inter ventricular septum bulging to posterior of heart and compressing its overlying muscle as whitish round mass. the patient underwent elective surgery by evacuation of septal hydatid cysts...

Background Uterine rupture in a term pregnancy is an adverse and rare event with serious maternal and fetal consequences. The history of uterine septum resection is considered as a risk factor for uterine rupture. Women with such circumstances are thus recommended to be considered as having a high-risk pregnancy. Accordingly, their prenatal care should be implemented in shorter intervals during...

The neural crest origin of the aortopulmonary septum has led us to investigate the septum for a special function, and we designed the present study to assess the alteration, if any, in the dimensions of the aortopulmonary septum in hypertension. The dimensions of the aortopulmonary septum were measured by echocardiography in 36 hypertensive and 36 age- and sex-matched normotensive subjects. Ech...

BACKGROUND The Le Fort I osteotomy is one of the most widely used and useful procedure to correct the dentofacial deformities of the midface. The changes of the maxilla position affect to overlying soft tissue including the nasal structure. Postoperative nasal septum deviation is a rare and unpredicted outcome after the surgery. There are only a few reports reporting the management of this comp...
