The exposure of healthy volunteers to 200 ppm 1,1,1-trichloroethane increases the concentration of proinflammatory cytokines in nasal secretions
1999
Objectives: Irritating effects of organic solvents have usually been measured by means of questionnaires. The aim of the present study was to evaluate the sensitivity of different methods of detecting subclinical irritating effects. Methods: Twelve healthy, non-smoking students were exposed to 200 ppm and to 20 ppm 1,1,1-trichloroethane in an exposure chamber, using a crossover design. The amounts of interleukins (IL)-1β, IL-6 and IL-8 and prostaglandin E2 (PGE2) in nasal secretions were measured. Mucociliary transport time was determined with the saccharine test. Ciliary beat frequency of nasal epithelial cells was measured with video-interference contrast microscopy. Subjective symptoms w…
Long-term results (7 to 10 years) of endoscopic papillotomy for choledocholithiasis. Multivariate analysis of prognostic factors for the recurrence o…
1998
Abstract Background: The long-term outcome after endoscopic papillotomy is poorly defined. The aim of this study was to determine the long-term results of this method in the treatment of common duct calculi and to determine which prognostic factors are associated with the relapse of biliary symptoms. Methods: Between 1985 and 1988, 223 consecutive (149 women, mean age 67.9 years) patients underwent endoscopic papillotomy for duct stones; 127 had already undergone cholecystectomy or underwent this operation during the same hospitalization. Follow-up data were obtained retrospectively from the patients and patients' relatives and general practitioners. Results: The procedure was successful in…
Long term follow up of patients with chronic pancreatitis and pancreatic stones treated with extracorporeal shock wave lithotripsy
1999
BACKGROUNDThere have been conflicting reports as to whether pancreatic ductal drainage achieved by endoscopy and lithotripsy improves the clinical outcome of patients with chronic pancreatitis.AIMSTo determine the clinical outcome in patients with chronic pancreatitis who received extracorporeal shock wave lithotripsy (ESWL), and were followed up for two to eight years.METHODSEighty patients with severe chronic pancreatitis and endoscopically unretrievable obstructive stones underwent ESWL with a piezoelectric lithotripter between 1989 and 1996. Clinical status, relief of symptoms, further endoscopic or surgical interventions, and mortality were defined.RESULTSForty three (54%) patients wer…
Familial Sotos syndrome caused by a novel missense mutation, C2175S, in NSD1 and associated with normal intelligence, insulin dependent diabetes, bro…
2009
We report a familial Sotos syndrome in two children, boy and girl, aged 17 and 8 years, and in their 44 year old mother, who displayed normal intelligence at adult age, but suffered from insulin dependent diabetes mellitus, bronchial asthma, and severe lipedema. The underlying missense mutation, C2175S, occurred in a conserved segment of the NSD1 gene. Our findings confirm that familial cases of SS are more likely to carry missense mutations. This case report may prove useful to avoid underestimation of the recurrence rate of SS, and to demonstrate that the developmental delay may normalize, enabling an independent life and having an own family.
Prostaglandin E2 activates the ciliary beat frequency of cultured human nasal mucosa via the second messenger cyclic adenosine monophosphate.
2001
Prostaglandins influence the ciliary beat frequency (CBF) of ciliated nasal epithelial cells and a stimulatory effect has been described for prostaglandin E2 (PGE2). Until now, it is not known whether PGE2 has direct ciliostimulatory properties or acts through a second messenger. In this study we investigated whether cyclic adenosine monophosphate (cAMP) is implicated in the signal transduction pathway of PGE2-induced activation of CBF. Ciliated cells of the nasal mucosa were cultured for up to 5 days whereafter the culture medium was removed and the cells were incubated with different concentrations of test solutions. The ciliated cells were recorded under a phase-contrast microscope and v…
The importance of citrates in treatment and prophylaxis of calcium oxalate urinary stones
2017
About 10% of the people is the subject of an episode of kidney stones during their lifetime, about 70% of these people undergoes relapses. About 80% of the urinary stones contains calcium, of wich 80% is formed of calcium oxalate, in pure form or associated with calcium phosphate. Therefore we can saythat in most cases (about 65%) the urinary stones are composedof calcium oxalate. Use of supplements of potassium citrate and magnesium citrate can help in the prevention of kidney stones of calcium oxalate, but mostly they can be used in the days before a shockwaves lithotripsy treatment to make the stones more fragile to the effect of the shock waves. A case of successful treatment with magne…
Impact of Gallbladder Status on the Outcome in Patients with Retained Bile Duct Stones Treated with Extracorporeal Shockwave Lithotripsy
2002
BACKGROUND AND STUDY AIMS The use of endoscopic therapy in combination with lithotripsy techniques has become increasingly common in patients with complicated common bile duct stones. In many units, although this is controversial, cholecystectomy is then performed, because of possible subsequent cholecystitis and recurrence of choledocholithiasis. The aim of this study was to investigate whether gallbladder status influences the long-term outcome in patients after extracorporeal shockwave lithotripsy (ESWL) of common bile duct stones. PATIENTS AND METHODS Recruited for the study were 120 patients with an average age of 68 years (range 28 - 86). They were selected from 137 consecutive patien…
Single-incision laparoscopic cholecystectomy: Our experience and review of literature
2016
Aim After the revolution in the surgery of gallbladder stones represented by the laparoscopic cholecystectomy, we tried a new technique that further maximize the aesthetic results and that at the same time is of easy learning for young surgeons. Patients and methods From January 2011 to December 2012 we performed at our department 320 cholecystectomy: 27 in laparotomy and 293 in laparoscopy. Of these, 88 underwent to Single Incision Laparoscopic Surgery (SILS), namely the Single Incision Laparoscopic Cholecystectomy (SILC), in recruited patients aged between 19-65 years; 56 patients were females and 32 were males. Results The laparoscopic cholecystectomy with the SILS methodology is a safe …
Complementary feeding and "donner les bases du goût" (providing the foundation of taste). A qualitative approach to understand weaning practices, att…
2013
http://www.sciencedirect.com/science/article/pii/S0195666313003814; International audience; Complementary feeding (CF) practices vary within and across cultures but have been investigated only to a very limited extent. It is however important to understand CF practices and how they differ, as CF sets the foundation for children's later food choices. The present study was set out to examine practices, attitudes and experiences of CF including the introduction of vegetables amongst French mothers (n = 18, 25-39 years). Thematic analysis of transcribed focus groups and interviews revealed the perceived importance of the weaning period, as a critical milestone for infants' development but with …
Doppler and B-mode ultrasound for avascular nephrotomy.
1983
AbstractDoppler sonography for intraoperative localization of the intrarenal arteries combined with B-scan sonography for intraoperative visualization of stones allows complete stone removal via small radial nephrotomies for which clamping of the renal artery is no longer necessary. Since September 1980 we used this technique on 35 patients with staghorn or recurrent calculi. The main advantages of this technique are exact and quick stone localization, minimal loss of renal function owing to preservation of the intrarenal vascular system, and no need for renal ischemia and cooling.
