Sialolitiasis parotídea del conducto de Stensen

2006

La litiasis salival es una afectación consistente en la obstrucción mecánica de una glándula salival o de su conducto excretor, debido a la formación de concreciones calcáreas o sialolitos, lo que determina una ectasía salival, pudiendo provocar la dilatación posterior de la glándula. La sialolitiasis supone el 30 % de la patología salival y afecta principalmente a las glándulas submaxilares (83 a 94 %), seguida por la glándula parótida (4 a 10 %) y las glándulas sublinguales (1 a 7 %). En este trabajo presentamos el caso de un paciente varón de 45 años que presentaba mal olor y sabor de boca en el momento de las comidas y afecto de un cálculo salival a nivel del conducto de Stensen izquier…

Electromagnetically generated extracorporeal shock waves for gallstone lithotripsy: in vitro experiments and clinical relevance.

1989

. First generation shock wave sources have been proved to disintegrate gallstones effectively, but they require the immersion of the patient's body in a tank of water. A recently developed second generation shock wave source (Siemens-Lithostar, Erlangen, FRG) generates shock waves electromagnetically. It presents several novel features. In particular the waterbath can be omitted and due to lower shock wave pressure general anaesthesia is not required. In vitro studies showed that 36 out of 38 gallstones (11–30 mm in diameter) could be disintegrated. Two concrements resisting lithotripsy were pure white cholesterol stones. Independent of shape, size, and composition (cholesterol or pigment) …

Sialoendoscopy: state of the art, challenges and further perspectives. Round Table, 101st SIO National Congress, Catania 2014

2015

This draft of the Official Round Table held during the 101(st) SIO National Congress is an updated review on sialoendoscopy, a technique used for diagnosis and treatment of obstructive pathologies of salivary glands in a minimally invasive fashion. This review treats many aspects of salivary gland endoscopy, starting from anatomy to deal with the more advanced surgical techniques and analyses the main decisional algorithms proposed in the literature. In addition, particular attention was directed to the current limitations of this technique and to the potential developments that sialoendoscopy could have in the near future.Questo testo è un estratto della Tavola Rotonda Istituzionale tenuta…

Towards data-driven medical imaging using natural language processing in patients with suspected urolithiasis.

2020

Abstract Objective The majority of radiological reports are still written as free text and lack structure. Further evaluation of free-text reports is difficult to achieve without a great deal of manual effort, and is not possible in everyday clinical practice. This study aims to automatically capture clinical information and positive hit rates from narrative radiological reports of suspected urolithiasis using natural language processing (NLP). Methods Narrative reports of low dose computed tomography (CT) of the retroperitoneum from April 2016 to July 2018 (n = 1714) were analyzed using NLP. These free-text reports were automatically structured based on RadLex concepts. Manual feedback was…

A temporary endoscopic solution that significantly improves the prognosis of Bouveret’s syndrome

1991

We report the case of a 73-year-old woman who was hospitalized for mild abdominal pain after her referral following a diagnostic assessment of acute lithiasic cholecystitis. After the spontaneus regression of her painful symptoms and fever and several days of well-being, her clinically acute abdominal features suddenly showed an obstruction of the upper gastrointestinal tract. An emergency esophagogastroduodenoscopy (EGDS) confirmed that a large gallstone completely obstructed the pylorus as previously demonstrated by an ultrasound examination of the gallbladder. During the course of endoscopy, removal of the gallstone from the duodenum was achieved by pulling it into the stomach; the patie…

Changes in gallbladder motor function during the female cycle — a risk factor leading to gallstone formation?

1982

The gallbladder volume of eight women with stable cycles was determined by sonography. Furthermore, gallbladder contraction — following an orally administered fatty meal and the spontaneous refilling of the empty gallbladder — was quantitatively examined. The formula of a rotation ellipsoid, which has been proven to be adequately accurate in in vitro studies, was used for calculating the gallbladder volume. In the gestagen phase (21st or 22nd day) the intraindividual studies showed greater fasting volumes, higher residual volumes after contraction, slower gallbladder emptying, and retarded refilling of the empty gallbladder as compared to the estrogen phase (12th or 13th day). The hormonall…

PATHOPHYSIOLOGY AND CLINICAL ASPECTS OF URINARY LITHIASIS

2007

Urine is a complex balanced solution containing dissociated and non-dissociated solutes. Any variation in urine saturation grade (number of crystals dissolved in a volume of urine), urinary pH and the concentration of crystallization inhibitors can break the normal existing balance and lead to urolithiasis. In the present article we analyze the principal mechanisms (absorptive, renal, resorptive) of hypercalciuria. It will be also shown how heredity directly influences the clinical aspects of cystine, xanthine and oxalate lithiasis and how diet, in association with metabolic disorders, interferes in uric acid and oxalate stone formation. Finally, we report on the roles of urinary tract malf…
