Transvestibular Urethrolysis.

2011

Bladder outlet obstruction with obstructive and irritative urinary symptoms may be a complication of surgery for female urinary incontinence. In presence of persistent symptoms the therapy is surgical and usually consists in an accurate urethrolysis. The way of approach is generally transvaginal. In this paper we propose and describe our experience with a transvestibular approach.From 1995 to 2009 18 women who had undergone anti-incontinence surgery (TVT 12 pts, TOT 3 pts, Burch retropubic colposuspension 3 pts) with obstruction and/or irritative symptoms underwent to a transvestibular urethrolysys. Five patients had urinary retention the other patients had post voiding residual urine100 ml…

Trans-visceral migration of retained surgical gauze as a cause of intestinal obstruction: a case report

2008

AbstractIntroductionA retained surgical sponge in the abdomen is uncommon although it is likely that this finding is underreported in the medical literature. The intravisceral migration of retained surgical gauze is even rarer, as demonstrated by the very few cases reported.Case presentationThree years after undergoing anterior resection of the rectum, a 75-year-old man presented with symptoms of small bowel obstruction. Plain abdominal radiography and CT showed a radio-opaque marker; a foreign body was suspected, probably a piece of retained surgical gauze. An ileotomy of about 5 cm. was performed to confirm this diagnosis and remove the gauze.ConclusionAlthough rare, retained gauze in the…

Treatment of Pulmonary Disease of Cystic Fibrosis: A Comprehensive Review.

2021

Cystic fibrosis (CF) is a genetic disease that causes absence or dysfunction of a protein named transmembrane conductance regulatory protein (CFTR) that works as an anion channel. As a result, the secretions of the organs where CFTR is expressed are very viscous, so their functionality is altered. The main cause of morbidity is due to the involvement of the respiratory system as a result of recurrent respiratory infections by different pathogens. In recent decades, survival has been increasing, rising by around age 50. This is due to the monitoring of patients in multidisciplinary units, early diagnosis with neonatal screening, and advances in treatments. In this chapter, we will approach t…

Direct measurement of left ventricular outflow tract by transthoracic real-time 3D-echocardiography increases accuracy in assessment of aortic valve …

2007

Evaluation of aortic valve stenosis is a major clinical application of echocardiography. The widely employed continuity equation requires determination of the left ventricular outflow tract (LVOT) area. We aimed at testing whether direct area measurement in a volume data set is superior to conventional calculation from the LVOT diameter.We performed LVOT measurement in 20 normal subjects and 83 patients with moderate to severe aortic stenosis with a transthoracic real-time three-dimensional echocardiography (3D-TTE) technique in two systolic frames. The off-line 3D-evaluation allows full choice of section planes within the acquired volume data set. The aortic valve area was calculated from …

Deep learning architectures for automatic detection of viable myocardiac segments

2021

Thesis abstract: Deep learning architectures for automatic detection of viable myocardiac segmentsAccurate myocardial segmentation in LGE-MRI is an important purpose for diagnosis assistance of infarcted patients. Nevertheless, manual delineation of target volumes is time-consuming and depends on intra- and inter-observer variability. This thesis aims at developing efficient deep learning-based methods for automatically segmenting myocardial tissues (healthy myocardium, myocardial infarction, and microvascular obstruction) on LGE-MRI. In this regard, we first proposed a 2.5D SegU-Net model based on a fusion framework (U-Net and SegNet) to learn different feature representations adaptively. …

Relationship between rhinitis duration and worsening of nasal function

2008

BackgroundWhile it is well known that asthma is characterized by airway remodeling, few studies instead have investigated this issue in patients with allergic rhinitis (AR).ObjectiveThe aim of the study was to evaluate nasal function, ie, nasal airflow, in a cohort of patients with persistent AR (PER).MethodsOne hundred patients, 50 with short-term and 50 with long-term PER, were prospectively and consecutively evaluated, clinically evaluated by visit, skin prick test, and rhinomanometry.ResultsNasal airflow values were significantly lower (median flow: 348 mL/sec) in patients with long-term rhinitis (median duration nine years) as compared to patients with short-term (median duration one y…

Radiofrequency volumetric tissue reduction (RFVTR) of inferior turbinates: a new method in the treatment of chronic nasal obstruction.

2001

Twenty-two Caucasians (16 male and 6 female) with chronic bilateral nasal obstruction due to hypertrophic inferior turbinates were followed up over a three-month period. They were assessed by clinical examination, as active anterior rhinometry, and acoustic rhinometry before and after topical decongestion, preoperatively and three months after surgery. All patients were treated by application of radiofrequency-volumetric-tissue reduction (RFVTR, or somnoplasty) to both inferior turbinates. Initial postoperative edematous response disappeared during the first week after RFVTR. Three months postoperatively 20 of 22 patients (91%) reported subjective improvement of nasal patency. The average …

The impact of in-situ balloon occlusion of the renal artery and hypothermic perfusion on renal blood flow

1978

Unilateral renal blood flow was evaluated in-situ in 13 dogs by cineangiodensitometry and microsphere distribution studies before and after intermittent balloon occlusion with and without hypothermic perfusion of one kidney. The contralateral kidney served as control. No significant difference in renal blood flow and vascular resistance was noted before, and 5, 30 and 60 minutes after unilateral intra-arterial manipulation. Compartmental flow distribution studies in 5 dogs revealed no evidence of alteration of intra-renal haemodynamics. In a clinical pilot study, unilateral renal blood flow measured by cineangiodensitometry showed no change of clinical significance 5 and 60 minutes after in…

Pilotpētījums par nazālo elpceļu obstrukcijas kvantitatīvo noteikšanu

2020

Pilotpētījums par nazālo elpceļu obstrukcijas kvantificēšanu Ievads Nazālā obstrukcija ir izplatīta problēma visā pasaulē, kas ievērojami ietekmē cilvēka dzīves kvalitāti. Neskatoties uz šīs problēmas prevalenci, pieejamās obstrukcijas pakāpes mērīšanas metodes ir neprecīzas. Ir novērota vāja korelācija starp kvantificēto obstrukcijas pakāpi, kas tiek iegūta lietojot mūsdienu metodes un kvalitatīvo obstrukcijas pakāpi, ko apraksta pacienti. Mērķis Šī ekperimentālā pētījuma mērķis ir, pirmkārt, radīt innovatīvu instrumentu, kas simulē specifiskas deguna obstrukcijas pakāpes. Tas būtu instruments, kas spētu potenciāli kvantificēt pacientu subjektīvās sajūtas par deguna obstrukciju. Otrkārt, m…
