- Abstract
Purpose: We had for objective to assess odontogenic disorders associated to a congenital piriform aperture stenosis and to study their various presentations., Methods: Twelve patients presenting with a congenital piriform aperture stenosis, 1 week to 3 months of age, were retrospectively included from 1998 to 2008. All patients underwent an initial CT scan to evaluate the temporary dental germs., Results: Deciduous dental germs were abnormal in 75% of the cases. Thirty-three percent had a single median maxillary central incisor., Discussion: The concept of solitary median maxillary central incisor syndrome makes for a more pathophysiological approach of this type of disease, with various clinical presentations, corresponding to various levels of severity of a same pathological process., (Copyright © 2013 Elsevier Masson SAS.

- Abstract
The present paper intends to review diagnosis and treatment issues of bladder neck anastomosis stricture after radical prostatectomy for localised prostate cancer. Even though cancer control is not necessarily a concern, quality of life may be greatly altered. Patients may suffer from dysuria, urgency and the feeling of incomplete bladder emptying. Flowmetry, cystoscopy and cystography contribute to its diagnosis. Treatment should be graded according to the severity of the disease and the quality of life of the patient. Cold-Knife incisions and pneumatic dilatation are the first line treatments. Holmium laser shows good results on the stricture in a second line treatment. A two-stage strategy with an endoluminal stent followed by artificial urinary sphincter implant is the ultimate option to manage severe strictures, while maintaining acceptable quality of life. Continence sparing is the challenge of the treatment of this type of stricture., (Copyright (c) 2009 Elsevier Masson SAS. All rights reserved.)

- Abstract
Aim of Study: To report cases from Vietnam of intestinal tuberculosis disease, which is uncommon but did not disappear in occidental countries., Materials and Methods: Seventy-six patients were included in this retrospective study. Mean age was 40 years and sex ratio M/F was 6. Diagnosis was established on pathological examination of resected specimen or on presence of Mycobacterium tuberculosis or by polymerase chain reaction., Results: Intestinal obstruction or subobstruction was the most usual symptom (68%), and thereafter peritoneal symptoms with pain and tenderness (17%). Five patients had intractable digestive haemorrhage. Thirty-six patients had no past history or active pulmonary tuberculosis (47%). Lesions of stenosis on barium enema and thickness of intestinal wall on CT-scan were not specific. Sixty-two patients were operated on (82%) and 14 were not. Surgical techniques differed according symptoms, site and type of lesions. Intestinal resections were performed in half of the patients, others undergoing stomies or enterolysis. There were eight postoperative deaths (13% of patients operated on), seven out of these deaths were attributable to cachexy. In the postoperative period, all the patients were medically treated and follow-up in the antituberculosis centre of Hanoi., Conclusion: Symptomatology and operative findings of intestinal tuberculosis are similar to those observed in Crohn's disease, and sometimes in amoeboma or lymphoma. In face of stenosis and intestinal wall thickness, probability of intestinal tuberculosis is high in endemic area, but diagnosis must be suspected in occidental countries, mainly in patients immigrated coming from these areas, patients with immuno-deficiency even if they did not have past or present pulmonary tuberculosis.

- Abstract
Publications of central veins stenoses were still frequently related though improvements of the catheter quality and the catheterism procedures since the 1980's. The review of the literature during the period of 1980-2000 helped us in observations as following: Global incidence was 15.6% in subclavian vein stenoses (SVSC), 2.7% in jugular stenoses (SVJ) and 0-3.8% in femoral stenoses (SVF). The "non-symptomatic" SVSC, detected by Venograms, represented only 23-33% of all SVSC publications but they showed higher incidence in the patients than "symptomatic" SVSC: 41% versus 3.3% just as for non-symptomatic SVJ: 9% versus 1.6% in symptomatic SVJ. Venograms with "in-arm-injections" mostly used by authors should underevaluated the incidence of SVJ. Mecanisms were betterly detailed with SVSC than SVJ and SVF (Catheter quality, venous lesions by portions and artérialisation by fistulas, anatomic constraints of the subclavian vein in the triangle space behind the clavicular, fibrin sleeve, thrombus and microtraumatism of the Veins walls...). Global results of the treatment, though improvement with angioplasty-Stent, remained disappointing by early recurrences. Worsened dialysis adequacy and life quality of the patients should be the issues. The number of the catheters currently used in temporary accesses, including the subclavian veins, and in permanent accesses was still higher than DOQI/NKF recommendations. Anticipated creations of Fistulas should be one efficient prevention.

- Abstract
Central venous stenosis (ST) and thrombosis (TB) related to catheter (KT) had been reported mostly for the subclavian vein. We performed a systematic cavographic study to evaluate the prevalence of these complications in 51 hemodialysis patients with present or previous history of tunneled internal jugular catheter. Each of them had used one or several KT (1.8 +/- 1.4 KT) for a mean 28 +/- 26 month cumulative time (i.e. 43,584 days total exposure time). Fifty percent of the KT were PermCath Quinton and 50% were Twincath (uncuffed) or CS 100 (cuffed) Medcomp. Twenty-seven had no ST (53%, group I), 24 had one or several significant ST (47%, group II) of superior Vena Cava (SVC, n = 4), inferior Vena Cava (IVC, n = 1), Brachio-cephalic Vein (BCV, n = 5) and subclavian vein (SC, n = 10), or a TB of SVC (n = 1), IVC (n = 3), BCV (n = 3), SC (n = 2). This accounts for an incidence of 0.55 ST or TB/1000 patient-days. Five of the twelve subclavian ST and TB had no history of previous subclavian catheter. Comparison between the two groups showed no differences according to age, time on dialysis, diabetes, hematocrit, CRP, cumulative time with catheter, catheter-related infections, type of catheter and anticoagulant treatment. IVC catheter tip's position is an important risk factor for TB and ST (4/6). Twelve group II patients had ST or TB-related symptoms, with a functional AV fistula in 9 cases. Eleven patients underwent repeated percutaneous angioplasty with 4 additional Wallstents and in 2 cases an AV fistula need to be closed. Central venous ST and TB after a jugular KT is extremely frequent, mostly without any symptoms. Consequences on peripheral or central vascular access, cost and poor long-term patency rate of angioplasty are of major importance. These results incite us to further reduce the catheter use in dialysis patients.

- Abstract
The aim of this study was to assess the immediate efficacy and the medium-term risks and results of percutaneous transluminal coronary angioplasty (PTCA) in early post-infarction unstable angina. Thirty-six patients were included for a series of 248 consecutive PTCA procedures performed between December 1985 and January 1989. The average age was 56 years (range 35 to 84 years). The initial infarct was anterior (N = 16), inferior (N = 15), lateral (N = 5), without a Q wave (N = 22), transmural (N = 14) and treated by thrombolysis in 42 p. 100 of cases. The interval between initial infarction and PTCA was 16 +/- 3 days. A primary success was obtained in 33 cases (92%). One patient died of electromechanical dissociation at the beginning of the procedure. Two infarcts occurred due to acute coronary occlusions. None of the patients required emergency coronary bypass surgery. The specific risk of PTCA in early post-infarction unstable angina is acute coronary occlusion. This complication was observed in 9 patients (25%) and it required immediate repeat PTCA, associated with thrombolytic therapy in four cases. Coronary occlusion was more common in patients with transmural infarcts than in those without Q-waves (43% vs 14%; p less than 0.01) and in patients treated initially by thrombolysis compared with those not treated by thrombolysis (40% vs 15%; p less than 0.05). No fatalities or reinfarctions occurred during follow-up (average 9 +/- 8 months, range 2 to 35 months). A good clinical result was maintained in 71 per cent of patients treated by PTCA alone. Seven repeat PTCA procedures and 3 coronary bypass operations were performed during follow-up.(ABSTRACT TRUNCATED AT 250 WORDS)

- Abstract
The aim of this prospective study was to compare the incidence of restenosis after percutaneous transluminal coronary angioplasty (PTCA) in patients with stable and unstable angina before the procedure. Between January 1984 and February 1986, 344 patients with stable angina and 228 patients with unstable angina underwent PTCA. The primary success rate was 86.3 per cent in patients with stable angina (297 patients) and 87.7 per cent in patients with unstable angina (200 patients). The patients were recalled for systematic control coronary arteriography at 30, 60, 90, 120 or 150 days, and was obtained in 83.8 per cent of patients with stable angina and in 86 per cent of patients with unstable angina. The degree of stenosis before and the angiographic changes after PTCA and at control coronary arteriography were evaluated by a computer-assisted automatic contour detection system. The three criteria of restenosis were: 1) over 50 per cent loss of the benefit of PTCA, 2) residual post-PTCA stenosis increasing from less than 50 per cent to more than 50 per cent at control arteriography, 3) a decrease in the minimum intraluminal diameter of at least 0.72 mm with respect to the immediate post-PTCA result. A comparison between the two groups of patients showed that the average age was slightly greater in patients with unstable angina (56 +/- 9 years vs 58 +/- 9 years, p = 0.047). Apart from this difference, the two groups were comparable with regards to the average number of lesions dilated per patient, the date of control arteriography, the severity of the coronary artery disease and previous bypass surgery, angioplasty and infarction.(ABSTRACT TRUNCATED AT 250 WORDS)
