Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL): a good practice guide, pictorial review, and new perspectives.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare but emerging T-cell non-Hodgkin lymphoma. It has two distinct subtypes, "effusion-only" or "mass-forming" disease, arising around implants in patients with in situ or previous history of textured-surface breast implants. The clinical, histopathological and imaging features are unique and nuanced as compared to primary breast malignancy and other lymphoma categories. Prompt recognition and diagnosis triggers referral to appropriate BIA-ALCL centres and initiation of treatment, with potential for excellent prognosis. Definitive management of both subtypes involves implant and capsule removal; systemic therapy is reserved for mass-forming disease and advanced-stage disease. There have been recent crucial advances in the diagnostic pathway, with publication of national and international guidelines: from the UK Medicines Healthcare products Regulatory Agency (MHRA) Plastic, Reconstructive and Aesthetic Surgery Expert Advisory Group (PRASEAG), and the United States National Comprehensive Cancer Network (NCCN). This review provides a practical guide to the clinical work-up of BIA-ALCL, enabling optimisation of the diagnostic imaging pathway, with representative cases.

[Mitral stenosis and acute hemolytic anemia after mitraclip]. / Sténose mitrale et anémie hémolytique aiguë après mitraclip.

Mitraclip corrects mitral regurgitation in a less invasive way than cardiac surgery. These procedures are becoming widespread with the emergence of new complications. We report a rare case of mitral stenosis associated with acute hemolytic anemia after mitraclip treatment in an 82-year-old patient. The cause of this stenosis in our case is linked to the placement of two clips and an increase gradient in post-procedure. The mechanism of hemolysis could be due to the persistence of mitral leaks resulting in strong collisions against the clip.

Treatment of mandibular osteoradionecrosis by periosteal free flaps.

Mandibular osteoradionecrosis (ORN) is one of the most serious complications of radiotherapy of the head and neck, and is characterised by hypoxia, hypovascularisation, and hypocellularity. Periosteal free flaps have intrinsic osteogenic, and extrinsic neoangiogenic, properties that are related to the periosteum. Our objective was to present our experience with the use of periosteal free flaps in the treatment of ORN (Notani class I or II) that are refractory to conservative management or have a large area of bone (≥2 cm) exposed. We organised a single-centre, retrospective study between 2003 and 2013 and describe the management of 11 patients (4 women and 7 men) who were being treated for refractory mandibular ORN. Thirteen periosteal free flaps were used: inner femoral condylar periosteum (n = 4), iliac crest (n = 1), external brachial with humeral periosteum (n = 1), and forearm with radial periosteum (n = 7). During follow-up we found three acute complications (haematoma, partial necrosis, and total vascular necrosis) that required immediate construction of a second periosteal free flap. There were also two chronic complications (fistula and post-traumatic fracture). With only one progressive lesion identified, the ORN was stopped in 11/12 patients. Two examples of osteoconduction were identified on postoperative images at six months and two years. Because of its osteoconductive and neoangiogenic capacities, the periosteal free flap seems to offer a real biological dimension to the treatment of ORN, and its efficiency favours its early revascularisation.

[Pseudo-aneurysm of mitro-aortic continuity: a rare complication after aortic valve replacement]. / Le pseudo-anévrisme du trigone fibreux aorto-mitral : une complication rare du remplacement valvulaire aortique chirurgical.

Pseudo-aneurysm of the fibrous continuity zone between the aortic and mitral valves, the so-called "mitral-aortic intervalvular fibrosa" is a rare complication of acute infective endocarditis, rarely after an aortic valve replacement. We report the case of a large pseudo-aneurysm occurred in a 70-year-old man, who had a history of surgical aortic valve replacement 3 years before. There were no biological or clinical evidence for infective acute endocarditis. The originality of this observation can be summarized in three points: the late onset after surgery, the absence of any infectious context and the chronic nature of pseudo-aneurysm, without any complication during a follow-up of 12 months. Transesophageal echocardiography remains the best diagnostic tool.

[Part III: free periosteal flaps as a treatment for mandibular osteoradionecrosis]. / Partie III : les lambeaux libres périostés dans le traitement des ostéoradionécroses mandibulaires.

INTRODUCTION: The vascularized periosteal free flap transposes a non-irradiated soft tissue with neo-angiogenesis, bone induction, and osteogenesis qualities. Its technique and interest are studied for early osteoradionecrosis. MATERIAL AND METHOD: A retrospective study was made between 1992 and 2002. Thirty-four patients were selected among the 59 cases operated for osteoradionecrosis; all patients were classified stage II and I on the Epstein scale. Twenty-six patients were reconstructed using a non-periosteum free flap (bone, muscular or cutaneous flap), and eight patients were reconstructed using a "periosteum free flap". The study was clinical, radiological, and histological. RESULTS: Osteoradionecrosis evolved for two of the eight patients having undergone periosteum free flap surgery. Operative morbidity and the number of reoperation were less important than for the rest of the series. The reconstruction was satisfactory on a functional and esthetic level. A bone production was noted for two patients of the "periosteum" group. DISCUSSION: Periosteum free flap surgery is an alternative for early osteoradionecrosis. The periosteum brings osteo-induction and osteogenesis, and revascularization recorded clinically, radiologically, and histologically, even on an irradiated area.

[Mandibular osteoradionecrosis: part I: severity factors]. / Ostéoradionécroses mandibulaires: partie I: facteurs de gravité

INTRODUCTION: The severe evolution for some patient presenting with osteoradionecrosis, even if classified in the same stages as other patients, suggests that there are aggravating factors. MATERIAL AND METHOD: A retrospective study was made between 1992 and 2002 on all patient operated for mandibular osteoradionecrosis. Fifty-nine patients were included and the mandibular defects were reconstructed with a bone or a composite free flap (fibula 21%, iliac crest 49%, scapula 6%, antebrachial 3%), and with a periosteal free flap (13%). RESULTS: The study included severe cases (87% of stage II or III) operated on several times without success. Free flap reconstruction was successful in 90% of the cases. However, complications were present in 60% of cases (24% minor complications, 48% major complications), and were more frequent with a higher stage. The analysis allowed identifying morbidity factors. DISCUSSION: Studying the morbidity allowed identifying severity factors of osteoradionecrosis; spontaneous onset, important irradiation (important dose, bone proximity of the tumor, bilateral damage), vascular damage (symphyseal localization, lack of sequestrum, facial artery ligature, active tobacco addiction), actinomycosis colonization, non-observance of medical treatment. Understanding aggravating factors should allow us to offer more efficient surgery on an early osteoradionecrosis stage, also decreasing the morbidity linked to reconstructive surgery.

[Treatment of acute coronary syndrome in a small volume center: "survival rate in hospital and at 2 years of follow up"]. / Prise en charge de syndrome coronarien aigu dans un centre de petit volume: "Survie hospitalière et suivi à deux ans"

UNLABELLED: We report our experience of the treatment of the coronary syndrome ST+ in a small volume center. PATIENTS AND METHODS: For a period of 1 year (September 2004 to September 2005), 110 patients were treated by emergency coronarography at the hospital in Vichy (France). These patients were followed up for a period of 2 years. RESULTS: This population was relatively elderly: 43.6% of the patients were above 75 years of age. One hundred patients (91%) were treated by emergency angioplasty with a success rate of 88%. The average waiting time for treatment in the coronarography ward is 55 minutes and 35 seconds. Mortality in hospital is 6.36% for the totally of the population. It should be noted that 10.9% of these patients were admitted in a state of cardiogenic shock (12 patients), 3 of whom (25%) have died. 3 of these received a CPIA. At the end of an average follow-up of 21.44 months the survival rate is 83.6%, including and incident-free survival rate of 61.8%. CONCLUSION: These results, comparable with what has been published in the literature, confirm the effectiveness of emergency coronary angioplasty as a method of revascularization even in a small volume center, in respect both of the survival rate in hospital and also of incident-free survival at 2 years.

[Management of antiplatelet therapy: a case report]. / Gestion des anti-agrégants plaquettaires en préopératoire: à propos d'un cas.

We report a personal case of myocardial infarction with flurbiprofen used instead of clopidogrel before an operation. We re-examined the literature concerning the management of the antiagregant treatment of the patient with angioplasty and/or stent who needs surgery. This management proves to be delicate and all the questions that it raises have not so far been answered in particular with regard to the problem of resistance to aspirin. Anyway this personal observation supports our view that contrary to certain recomendations flurbiprofène is not a satisfactory alternative to aspirin either with or without thiénopyridine.

[Mediatisation and "facial graft" or "to whom belongs the facial graft"?]. / Médiatisation et "greffe de visage" ou "à qui appartient la greffe de visage"?

Mediatisation of a scientific event could be neither controlled, nor verifiable. The experience which has been lived through the first worldwide allotransplantation of composite tissues of the face confirms that the actors of a surgical innovation are not the owners. Because there is neither confidentiality nor possible patent. Curiously the scientific world, providing with a sharing ethic, which rightly privileges the free spreading of knowledge in the way that most people could benefit of it. Obviously it is made without denied controversy, for truth as purpose. This scientific word that way joins the media one, with a specific ethic of the duty of information, but also interested in mercantile preoccupations quick to cultivate controversy not to enlighten this truth but to better sell pictures or papers. Than the author should only sustain this instrumentation which could certainly flatter him, and from which he could used, but in reality that paralysed him a little to go on in serenity with his shadow worker way.

[The "tako-tsubo" syndrome: report of two cases]. / Le syndrome de "tako-tsubo": à propos de deux cas.

The "tako-tsubo" syndrome, initially described by Japanese authors is an apical akinesis of the left ventricule without significant coronary artery disease, with a moderate elevation of troponine I. We report 2 cases of women (with an average age of 68 years). They were refered for suspected acute coronary syndrome including on admission chest pain and ST segment elevation. Cardiac ultrasonography shew an apical akinesis. Coronary angiography didn't show significant coronary lesion. A moderate elevation of troponine was noted but no significant elevation of CPK. The prognosis has been excellent for these 2 patients. We observed a ventricular tachycardia due to QT lengthening in 1 case treated anteriorly by Flecaïn which spontaneously resolved. The first month, the electrocardiogram and cardiac ultrasonography anomalies disappeared totally. The treatment is based on beta-blockers, aspirin, statines, ACE. In the two cases, we didn't find arguments for myocarditis, recanalized thrombosis, coronary spasm, pheochromocytomas, but a risk factor is inboth: emotional stress. Maybe the diagnosis could be easier with the submillimeter cardiac computed tomography.

[Results of percutaneous coronary intervention in a hospital with a low case load]. / Angioplastie coronaire dans un centre de petit volume.

Since efficacy of small volume centers performing coronary and angioplasty is questioned, we present our data for 2003. In 2003, 669 coronary examinations were performed in our unit (average age 68 years, 67% men) with 215 angioplasties. We take charge essentially Acute Coronary Syndrome (99%), with 37% ACS ST +. The radical approach was taken in 15% of cases. We used anti GP IIb/IIIa in 67% of cases (only abciximab), the rate of stenting was 84% with 43.6% of Direct Stenting. The primary angiographic results were good in 98% of cases. The rate of Restenosis was 6%. The hospital mortality was 2.8%. So we think that coronary and angioplasty in a small volume center can be performed with safety and a level of success in accordance with the data of the literature.

Human S-antigen determinant recognition in uveitis.

PURPOSE: Soluble antigen (S-Ag) is a member of the arrestin family of protein with which it shares a high level of homology. It is an immunologically privileged retinal antigen that can elicit experimental autoimmune uveitis (EAU) and is thought to be a target for ocular inflammatory diseases. This study was conducted to identify in humans, the immunogenic determinants of human S-Ag and to establish whether a specific response profile occurs in particular ocular inflammatory conditions. METHODS: Peripheral blood lymphocyte responses were measured against a panel of 40 overlapping synthetic peptides of human S-Ag in patients with chronic uveitis and compared with control subjects. Patients with Behçet disease, sarcoidosis, Vogt-Koyanagi-Harada, and sympathetic ophthalmia were tested. RESULTS: A limited number of immunodominant determinants were identified for Behçet disease and sarcoidosis. These were all located at sites of limited homology with other known arrestins. In addition, several individual patients had prominent proliferative responses to multiple determinants well above that of control subjects. This determinant spread was observed in all disease entities except sympathetic ophthalmia, which did not show any immunoreactivity to S-Ag. Significant response shifts were also noted over time in two patients. CONCLUSIONS: The results indicate that there are specific immunodominant determinants to human S-Ag in patients with certain forms of uveitis. However, in individual patients, response is not limited to these determinants. In the chronic stage of disease, response is spread over many determinants.

Balloon versus patch angioplasty as an adjuvant treatment to surgical thrombectomy of hemodialysis grafts.

BACKGROUND: Transluminal balloon angioplasty offers advantages to patch angioplasty. We evaluated the primary patency of thrombosed hemodialysis grafts that had undergone balloon angioplasty versus patch angioplasty as a salvage method. METHODS: We reviewed our experience with 22 consecutive intraoperative balloon angioplasties that were done in a 6-months period. The balloons used were noncompliant high pressure balloons. The balloon results were compared with those of 22 patients who had undergone patch angioplasties by the same surgeons. Age, gender, average time between graft insertion and revision, and number of prior revisions were analyzed. The two groups (patch and balloon) had similar ages (57 versus 58 years, respectively), gender distribution (12 women, 11 men versus 11 women and 11 men), average time of revisions before that particular procedure (15 versus 12 months), and average times of revisions before that procedure. RESULTS: Primary patencies of the patch and balloon group were respectively 86% versus 77% at 1 month, 45% versus 40% at 3 months, and 17% versus 28% at 6 months. There was no statistically significant difference between the two groups. Complications were comparable in both groups. CONCLUSION: Balloon angioplasty offers advantages to patch angioplasty, and we have shown similar patency rates. We recommend balloon angioplasty as a comparable method to salvage dialysis access grafts.

[Spontaneous dissection of coronary arteries. Apropos of 2 new cases with favourable course]. / Dissections spontanées des artères coronaires. A propos de deux nouveaux cas avec évolution favorable.

The authors report two new cases of spontaneous coronary dissection and discuss the real frequency of this disease as well as their generally reported poor prognosis. One case was a 32-year-old female migraine-sufferer treated by beta-blockers, who developed a rudimentary anterior myocardial infarction. The other case was a 43-year-old man who presented with a threatened anterior myocardial infarction without myolysis documented by cardiac enzymes. Both patients were smokers and both had an excellent outcome, clinically and on stress tests, with a follow-up on medical treatment alone of thirty months for the first case and fourteen months for the second case. These two new cases had a good prognosis, in contrast with the majority of cases published.

[Myocardial diverticulum of the left ventricle. Review of the literature apropos of a case]. / Diverticule myocardique du ventricule gauche. Revue de la littérature à propos d'un cas.

Left ventricular myocardial diverticular rare, as they represent 0.05% of all forms of diagnosed congenital heart disease. The circumstances of diagnosis are as variable as the multiplicity of symptoms with which they are associated. Consequently, treatments (or very often conservative management) are also varied and a standardized procedure has not been defined in this field, apart from a common sense approach.

Human S-antigen: presence of multiple immunogenic and immunopathogenic sites in the Lewis rat.

To identify the immunogenic and immunopathogenic sites present in human S-Antigen (S-Ag), 40 overlapping peptides that span the whole length of the S-Ag molecule were synthesized and tested in the Lewis rat model of experimental autoimmune uveitis. The most pathogenic sequences were 180-200, 340-360 and 350-370. Ten peptide sequences were identified that induced visible inflammation in the eye. A total of 23 peptides gave an in-vitro proliferative response following immunization in animals. The ability to generate an immune response was not linked to the pathogenic capacity of the sequence. The most pathogenic sequence, 340-360, was only weakly proliferative. Peptide 180-200 and peptide 340-360 gave higher T-cell proliferative responses, but these were lower than the maximal proliferative response observed with non-pathogenic sequences. In animals immunized with whole S-Ag, the majority of the determinants did not elicit a proliferative response, indicating that in S-Ag, the majority of the immunogenic determinants are cryptic and are not presented by the APC located in the lymph nodes.
