The basic concept of this technique is that mitral regurgitation can be corrected simply by suturing together the edges of the mitral leaflets just at the site where regurgitation occurs. In particular the free edge of the diseased leaflet is anchored to the corresponding edge of the opposing leaflet exactly where the regurgitant jet is located. When the jet of regurgitation is in the central p...

Ileal pouch-anal anastomosis surgery can be complicated by anastomotic leaks, leading to the formation of abscess and chronic sinus that have been routinely managed by a surgical approach. We developed the endoscopic needle knife sinusotomy (NKSi) technique, which has become a valid alternative. The basic principle of endoscopic NKSi is dissection and drainage of the sinus through its orifice i...

A 78-year-old man with a history of hypertension, dyslipidemia, and diabetes mellitus was referred to our hospital for the evaluation of a systolic murmur. Echocardiography showed severe aortic stenosis with a pressure gradient of 79.7 mmHg; aortic orifice size, 0.46 cm; and regurgitation, grade III (ejection fraction, 50.5%). Computed tomography revealed marked calcification adhering to the ao...

An equation was derived to describe the variation of the gas number density within the region between the orifice and the skimmer of an electrospray ionization mass spectrometer. The equation was used to develop a semi-quantitative model to predict the value of orifice voltages that lead to ion fragmentation within this region. This model made it possible to predict the types of solvent adducts...

The influence of liquid surface tension on the bubble formation from both rigid and flexible orifice has been investigated. The liquid phases under test are aqueous solutions with butanol or surfactants (cationic, non-ionic and anionic); static and dynamic measurements of liquid surface tension have been performed to characterise them. This study shows that the effect of surface tension on the ...

FIgure 2: Resolved erythema and secretion on the vulva, after treatment with zinc How to cite this article: Jiang S, Zhang Y, Zou X. Condyloma acuminata at urethral orifice complicated with hemophilia A. An Bras Dermatol. 2017;92(2):289-90. cause ulcer, bleeding, and damage to surrounding normal tissues, the urethral orifice would bleed during the treatment due to the deficiency of coagulant fa...

Ag/AgCl reference electrodes fabricated from pulled quartz tubes with orifice radii of 20 nm to 20 μm were characterized in KCl solutions of different concentrations by cyclic voltammetry. Linear current-voltage (i-V) dependence was observed with micropipet electrodes (with micrometer-sized tips) with the same concentration (0.01-1 M) of KCl inside and outside the pipet, but current rectificati...

OBJECTIVES We attempted to determine the accuracy and pitfalls of calculating the mitral regurgitant orifice area with the proximal isovelocity surface area method in a clinical series that included patients with valvular prolapse and eccentric jets. BACKGROUND The effective regurgitant orifice area, a measure of lesion severity of mitral regurgitation, can be calculated by the proximal isove...

Aim. To investigate the effect of orifice cavity depth on the sealing ability of Fusio, Fuji II, Fuji IX, and MTA"G". Materials and Methods. Ninety-two canals in extracted mandibular premolars were prepared, obturated, and randomly grouped into 4 groups. Each group was subgrouped for a 2 mm and 3 mm orifice cavity depth (n = 10). The remaining roots were divided to serve as positive and negativ...

Thirty-five children with pulmonary stenosis were catheterized from 1 day to 9 years of age and recatheterized after 2 weeks to 15 years. Right ventricular systolic pressure rose in 24 and the increase was greater in those under than over 5 years old. Pulmonary valve orifice area per square metre of body surface area increased in 12, but did not change in 3, and fell in 17; absolute decrease in...
