Surgical treatment of temporoparietooccipital cortical dysplasia in infants: report of two cases.

PURPOSE: Extensive multilobar cortical dysplasia in infants commonly is first seen with catastrophic epilepsy and poses a therapeutic challenge with respect to control of epilepsy, brain development, and psychosocial outcome. Experience with surgical treatment of these lesions is limited, often not very encouraging, and holds a higher operative risk when compared with that in older children and adults. METHODS: Two infants were evaluated for surgical control of catastrophic epilepsy present since birth, along with a significant psychomotor developmental delay. Magnetic resonance imaging showed multilobar cortical dysplasia (temporoparietooccipital) with a good electroclinical correlation. They were treated with a temporal lobectomy and posterior (parietooccipital) disconnection. RESULTS: Both infants had excellent postoperative recovery and at follow-up (1.5 and 3.5 years) evaluation had total control of seizures with a definite "catch up" in their development, both motor and cognitive. No long-term complications have been detected to date. CONCLUSIONS: The incorporation of disconnective techniques in the surgery for extensive multilobar cortical dysplasia in infants has made it possible to achieve excellent seizure results by maximizing the extent of surgical treatment to include the entire epileptogenic zone. These techniques decrease perioperative morbidity, and we believe would decrease the potential for the development of long-term complications associated with large brain excisions.

Rivascolarizzazione miocardica con arteria radiale: tecniche chirurgiche a confronto e risultati a breve termine [Myocardial revascularization and radial artery: different surgical strategies and short-term results]

BACKGROUND: The radial artery is routinely used as a graft for surgical arterial myocardial revascularization. The proximal radial artery anastomosis site remains unknown. In this study, we analyzed the short-term results and the operative risk determinants after having used four different common techniques for radial artery implantation. METHODS: From January 2000 to December 2004, 571 patients underwent coronary artery bypass grafting with radial arteries. Data were analyzed for the entire population and for subgroups following the proximal radial artery anastomosis site: 140 T-graft with the mammary artery (group A), 316 free-grafts with the proximal anastomosis to the ascending aorta (group B), 55 mammary arteries in situ elongated with the radial artery (group C) and 60 radial arteries elongated with a piece of mammary artery and anastomosed to the ascending aorta (group D). RESULTS: The mean age was 53.8 +/- 7.7 years; 55.5% of patients had a previous myocardial infarction and 73% presented with a satisfactory left ventricular function. A complete arterial myocardial revascularization was achieved in 532 cases (93.2%) and 90.2% of the procedures were performed under cardiopulmonary bypass and cardioplegic arrest. The operative mortality rate was 0.9%, a postoperative myocardial infarction was diagnosed in 19 patients (3.3%), an intra-aortic balloon pump was used in 10 patients (1.7%) and a mechanical circulatory device was implanted in 2 patients. The radial artery harvesting site remained always free from complications. The proximal radial artery anastomosis site was not a determinant of early hospital mortality. Group C showed a higher risk of postoperative myocardial infarction (p = 0.09), together with female gender (p = 0.003), hypertension (p = 0.059) and a longer cardiopulmonary bypass time. CONCLUSIONS: The radial artery and the mammary artery can guarantee multiple arterial revascularization also for patients with contraindications to double mammary artery use. The four most common techniques for proximal radial artery anastomosis are not related to a higher operative risk and they can be used alternatively to reach the best surgical results

Hidradenitis suppurativa of the groin treated by radical excision and defect closure by medial thigh lift: aesthetic surgery meets reconstructive surgery.

INTRODUCTION: Hidradenitis suppurativa of the groin is a chronic, relapsing inflammatory disease of the skin and subcutaneous tissues. Radical surgical excision is the treatment of choice. Often split-skin grafting or wound healing by secondary intention are used for defect closure, sometimes with disfiguring results. We describe our experience with radical excision of localised inguinal hidradenitis suppurativa and immediate defect closure with a medial thigh lift. PATIENTS AND METHODS: Our hospital database was searched for all patients presenting to our institution for surgical treatment of hidradenitis suppurativa between 2001 and 2006. Only patients with hidradenitis confined to the groin were included. Exclusion criteria were simple abscess incisions, recurrence after previous grafting or flap surgery and extension of the disease outside the groin and presence of clinical signs of infection at the time of surgery. We documented patient demographics, sizes of defects, complications, time of follow-up, recurrences and patient satisfaction. RESULTS: A total of 8 patients with localised inguinal hidradenitis suppurativa were identified and 15 thigh lifts were performed. Defect size assessed on pathologic examination of the excised specimens averaged 15.9 cm x 4.3 cm x 1.3 cm (length x width x depth). All wounds but one healed primarily. Functional and aesthetic results were satisfactory. No major complications and no irritations of the genital area were observed. No recurrences were observed either. CONCLUSION: We propose the medial thigh lift to be considered for immediate defect closure after radical excision of localised inguinal hidradenitis suppurativa provided that no perifocal signs of infection are present after debridement.

Interventions hybrides et malformations cardiaques congénitales [Hybrid procedures in congenital heart disease]

La complexité croissante de la prise en charge des malformations cardiaques congénitales impose des interventions chirurgicales et des cathétérismes cardiaques interventionnels fréquents. Chacune de ces techniques a ces limitations propres. Les interventions hybrides associent les avantages de la chirurgie cardiaque et du cathétérisme interventionnel. Dans notre expérience, les thérapies hybrides permettent de diminuer le temps de circulation extracorporelle, de diminuer la morbidité des interventions chirurgicales, de raccourcir le séjour du patient aux soins intensifs. Pour certaines malformations cardiaques congénitales complexes pour lesquelles il n'existe pas de chirurgie ou de thérapie interventionnelle idéale, les interventions hybrides sont en train de s'imposer comme la prise en charge incontournable. Increasing complexity in management of congenital heart disease imposes more frequent surgeries and interventions. Each technique has its own limitations, which could impair the anticipated result. Hybrid procedures join the advantages of cardiac surgery and interventions, creating a synergy in the management of these patients with cardiac anomalies. In our experience, hybrid procedures shorten cardiopulmonary bypass, reduce morbidity of surgery and reduce duration of stay in the intensive care unit. For some complex congenital heart diseases for which there are no ideal surgical or interventional options, hybrid procedures are becoming increasingly important in their management. Finally hybrid procedures allow surgeons and cardiologist to achieve complex procedures that could not be possible in another way

Measures to prevent surgical site infections: what surgeons (should) do.

BACKGROUND: The present study was designed to evaluate surgeons' strategies and adherence to preventive measures against surgical site infections (SSIs). MATERIALS AND METHODS: All surgeons participating in a prospective Swiss multicentric surveillance program for SSIs received a questionnaire developed from the 2008 National (United Kingdom) Institute for Health and Clinical Excellence (NICE) clinical guidelines on prevention and treatment of SSIs. We focused on perioperative management and surgical technique in hernia surgery, cholecystectomy, appendectomy, and colon surgery (COL). RESULTS: Forty-five of 50 surgeons contacted (90%) responded. Smoking cessation and nutritional screening are regularly propagated by 1/3 and 1/2 of surgeons, respectively. Thirty-eight percent practice bowel preparation before COL. Preoperative hair removal is routinely (90%) performed in the operating room with electric clippers. About 50% administer antibiotic prophylaxis within 30 min before incision. Intra-abdominal drains are common after COL (43%). Two thirds of respondents apply nonocclusive wound dressings that are manipulated after hand disinfection (87%). Dressings are usually changed on postoperative day (POD) 2 (75%), and wounds remain undressed on POD 2-3 or 4-5 (36% each). CONCLUSIONS: Surgeons' strategies to prevent SSIs still differ widely. The adherence to the current NICE guidelines is low for many procedures regardless of the available level of evidence. Further research should provide convincing data in order to justify standardization of perioperative management.

Termination of pregnancy among teenagers - why more surgical terminations?

Introduction: In 2012, a study by K. Chatziioannidou and S-C. Renteria showed that teenagers chose to undergo a surgical termination of pregnancy (TOP) more often than a medical TOP (mifepristone followed by misoprostol) when they decided to terminate a pregnancy. It also showed that the teenagers' choice for a medical versus surgical method is inversely proportional to the adults' choice although the efficiency of the medical method showed even better results for teenagers than for adults. According to the hypothesis made, the reasons for this choice might be influenced by the following facts: (i) the belated call to make an appointment, the medical procedure not being available after 9 weeks of gestation; (ii) the imperative request for confidentiality; (iii) the beliefs and subjective appreciation of the medical staff. Objectives: The aim of this retrospective and qualitative study is to analyse the reasons why, in case of a TOP, teenagers chose the surgical method more often than their adult counterparts. Material: (i) All teenagers who were admitted for an abortive procedure during 2011 in the in- or outpatient ward. (ii) The professional team (midwives and sexual and reproductive counsellors) in charge in the case of a TOP request. Methods: The information about the patient's history and the biopsycho- social data was retrieved from the patient files filled out by midwives and sexual and reproductive health counsellors during the first appointment for a TOP request or during its process. The professionals' appreciation was evaluated by means of a semi-structured questionnaire. Results: Concerning the choice of the method for a pregnancy termination, the results of our research show that: (i) Out of 47 teenagers, 27 chose the surgical method and 17 the medical method. (ii) Three had a second trimester abortion (which includes use of the medical method). (iii) Fifteen teenagers out of the 27 who chose a surgical method consulted between the 9th and 14th weeks of amenorrhoea and therefore did not have any other choice. The reasons for their 'late arrival' will be explained in detail. The 12 teenagers who arrived before the 8th week of amenorrhoea and chose to undertake abortion by suction & curettage under general anaesthesia did it for the following reasons: (i) Four were afraid of bleeding and pain. (ii) Five thought that the organisation of the surgical procedure was easier. (iii) Two did not trust the abortion pill. (iv) One was taken to her mother's gynaecologist where she had a D&C. Confidentiality was requested nine times out of 27 when choosing the surgical method, and six times out of 17 when choosing the medical method. Therefore, although confidentiality concerns a third of the teenagers' pregnancy termination requests, it does not seem to be a significant element for the choice of the method. As for the subjective appreciation of the professionals, the first results of the discussions seem to show that teenagers were reluctant or resistant towards the medical method. Conclusion: This study shows that the reasons why teenagers still prefer the use of the surgical over the medical method compared to adults, seem to include the late request for an appointment, fear of pain and bleeding and organisational issues. Confidentiality does not seem to greatly influence the teenagers' choice. Nonetheless, medical professionals seem to favour the suction curettage procedure performed under anesthesia because they associate young age with vulnerability and psychological frailty and consequently diminished ability to cope with pain and emotional distress during the medical procedures.

Multidisciplinary approach of lumbo-sacral chordoma: From oncological treatment to reconstructive surgery.

Lumbo-sacral chordoma is a rare, slow-growing tumor, arising from embryonic nothocordal remnants. Wide en bloc excision with clear margins remains mandatory to achieve satisfactory recurrence rates and disease-free survival. No chemotherapy has been demonstrated to be effective and radiotherapy is only marginally effective. Tyrosine kinase receptor inhibitors have showed encouraging results in locally advanced and metastatic chordoma. Reconstructive surgery may become very complex. Multidisciplinary approach in tertiary hospitals is always necessary. J. Surg. Oncol. 2015; 112:544-554. © 2015 Wiley Periodicals, Inc.

'Fast-implantable' aortic valve implantation and concomitant mitral procedures.

Concomitant aortic and mitral valve replacement or concomitant aortic valve replacement and mitral repair can be a challenge for the cardiac surgeon: in particular, because of their structure and design, two bioprosthetic heart valves or an aortic valve prosthesis and a rigid mitral ring can interfere at the level of the mitroaortic junction. Therefore, when a mitral bioprosthesis or a rigid mitral ring is already in place and a surgical aortic valve replacement becomes necessary, or when older high-risk patients require concomitant mitral and aortic procedures, the new 'fast-implantable' aortic valve system (Intuity valve, Edwards Lifesciences, Irvine, CA, USA) can represent a smart alternative to standard aortic bioprosthesis. Unfortunately, this is still controversial (risk of interference). However, transcatheter aortic valve replacements have been performed in patients with previously implanted mitral valves or mitral rings. Interestingly, we learned that there is no interference (or not significant interference) among the standard valve and the stent valve. Consequently, we can assume that a fast-implantable valve can also be safely placed next to a biological mitral valve or next to a rigid mitral ring without risks of distortion, malpositioning, high gradient or paravalvular leak. This paper describes two cases: a concomitant Intuity aortic valve and bioprosthetic mitral valve implantation and a concomitant Intuity aortic valve and mitral ring implantation.

Aortic root morphology: a paradigm for successful reconstruction.

Aortic root (AoR) components provide synchronous and precise 3D deformation of the aortic root during the cardiac cycle in order to ensure closure and opening of the three leaflets over a lifetime. Any deviation from the natural 3D morphology, such as with AoR annulus dilatation, enlarged sinuses and/or dilatation of the sinotubular junction, as in the case of ascending aortic dilatation, may result in disruption of the natural AoR function. Surgical treatment of AoR pathology has two modalities: the replacement of the aortic valve by artificial prosthesis or by preservation of the three leaflets and reconstruction of the aortic root components. Currently, there are two basic aortic root reconstruction procedures: aortic root sparing and aortic valve reimplantation techniques. Regardless of the technique used, the restoration of adequate cusp coaptation, is from a technical point of view, the most important element to consider. To achieve this, there are two requirements that need to be met: (i) the valve coaptation should be superior to the level of the aortic root base by at least 8 mm and (ii) the coaptation height per se has to be ≥5 mm. Successful restoration of the aortic root requires adequate technical skills, detailed knowledge of aortic root anatomy and topography, and also knowledge of the spatial pattern of AoR elements. Recently, there has been growing interest in aortic root reconstructive procedures as well their modifications. As such, the aim of this review is to analyse aortic root topography and 3D anatomy from a surgical point of view. The review also focuses on potential risk regions that one should be aware of before the surgical journey into the 'deep waters area' of the AoR begins.

Surgical techniques for maxillary bone grafting - literature review

For oral rehabilitation with implant-supported prostheses, there are required procedures to create the bone volume needed for installation of the implants. Thus, bone grafts from intraoral or extraoral donor sites represent a very favorable opportunity. This study aimed to review the literature on the subject, seeking to discuss parameters for the indications, advantages and complications of techniques for autogenous bone grafts.

Paddy Hartley: of faces and facades

Paddy Hartley's work is primarily concerned with the ways in which the human face can be repaired, manipulated and recontextualised, and the questions these processes raise about our concepts of beauty and disfigurement. Incorporating surgical and pharmaceutical equipment as well as steel, scrap metal, digital embroidery and textiles, Hartley sets out a critique of how we think about the face today. Taking as a starting point records of facially injured servicemen of the First World War and the pioneering surgery they underwent, Project Facade examines the impact of disfigurement on the human psyche, as well as tracing the development of early facial reconstructive surgery. His Face Corsets, meanwhile, examines attitudes towards cosmetic surgery and the beauty industry, providing a non-surgical means to brutally mimic the results of cosmetic procedures and beyond. The series gained notoriety and success in a wide variety of popular publications both nationally and internationally, and continue to feature in contemporary textiles and fashion publications. Paddy Hartley: Of Faces and Facades brings together these works in book form for the first time, presenting previously unpublished texts from David Houston Jones and Marjorie Gehrhardt, as well as drawings and photographs which document a remarkable creative process and a history that is still insufficiently explored.

Mesenchymal Stem Cells and Bovine Bone Mineral in Sinus Lift Procedures-An Experimental Study in Sheep

Introduction: New reconstructive and less invasive methods have been searched to optimize bone formation and osseointegration of dental implants in maxillary sinus augmentation. Purpose: The aim of the presented ovine split-mouth study was to compare bovine bone mineral (BBM) alone and in combination with mesenchymal stem cells (MSCs) regarding their potential in sinus augmentation. Material and Methods: Bilateral sinus floor augmentations were performed in six adult sheep. BBM and MSCs were placed into the test side and only BBM in the contra-lateral control side of each sheep. Animals were sacrificed after 8 and 16 weeks. Augmentation sites were analyzed by computed tomography, histology, and histomorphometry. Results: The initial volumes of both sides were similar and did not change significantly with time. A tight connection between the particles of BBM and the new bone was observed histologically. Bone formation was significantly (p = 0.027) faster by 49% in the test sides. Conclusion: The combination of BBM and MSCs accelerated new bone formation in this model of maxillary sinus augmentation. This could allow early placement of implants.

Immediate reconstruction following breast-conserving surgery: Management of the positive surgical margins and influence on secondary reconstruction

The efficacy of breast-conserving Surgery for the local control of early breast cancer has been repeatedly evidenced. Although immediate reconstruction following breast-conserving Surgery has been described, little information is available regarding surgical management in reoperative settings due to positive margins. We studied the influence of intraoperatively assessed and postoperatively controlled Surgical margin status on the type of breast-conserving Surgery and report our results regarding complications in a reoperative breast reconstruction scenario. All patients were seen by a multidisciplinary team who recommended breast-conserving surgery. According to the breast volume, ptosis and tumor size/location, the patients were also evaluated by a plastic Surgeon, who recommended reconstruction with the appropriate technique. Intraoperative assessment Of Surgical margins was determined by histological examination of frozen sections. The mean follow-up time was 48 months. Two hundred and eighteen patients (88.5%) underwent breast-conserving Surgery and immediate reconstruction. Twelve (5.5%) patients had a positive tumor margin after review of the permanent section. All patients underwent re-exploration. In 1.3%, a second reconstructive technique was indicated and in 2.2% a skin-sparing mastectomy with total reconstruction was performed. Our findings support the important role of the intraoperative assessment of surgical margins and its interference in the selection of reconstruction techniques and negative margins: however, it will not guarantee complete excision of the tumor.
