  5. A retrospective study of surgically excised phaeochromocytomas in Newfoundland, Canada

    Directory of Open Access Journals (Sweden)

    Joanna Holland


    Full Text Available Objective: A retrospective study detailing the circumstances surrounding diagnosis and treatment of pheochromocytomas with the associated genetic disorders. Materials and Methods: All patients with surgically excised pheochromocytomas in the Health Sciences Center, St. John′s, Newfoundland, Canada between January 2001 and December 2010 were retrospectively analyzed to determine associated familial syndromes, age, tumor size, symptomatology, and percentage of paragangliomas and bilateral pheochromocytomas. Pathology specimen reports, adrenalectomy lists and Meditech (electronic medical record diagnostic codes provided a comprehensive database for this study. Results: Twenty-four patients were studied; familial disorder patients comprised 42% (10/24. Average age at diagnosis was 57 among the sporadic and 34 in familial disorder groups (P = 0.006. Average tumor size was 4.5 cm in the sporadic group and 3 cm in the familial disorder group (P = 0.19. All atypical cases including bilateral or extra-adrenal tumors and malignancy occurred in familial disorder patients. Conclusions: The proportion of familial disorder patients (42% was higher in this study than would be expected, likely a result of the relatively high incidence of hereditary autosomal dominant disorders within Newfoundland. Among familial disorder patients, the average younger age at diagnosis and the smaller tumor size suggest syndromic pheochromocytomas may develop earlier, however they are more likely to be diagnosed sooner due to biochemical surveillance testing in known genetic disorder patients. We also demonstrate a relatively high incidence of surgically resected pheochromocytomas of 4.679/million/year in Newfoundland.

  6. Misdiagnosis of cutaneous leishmaniasis and recurrence after surgical excision. (United States)

    Bailey, Mark S; Langman, G


    Cutaneous Leishmaniasis (CL) occurs in British troops deployed to Belize, Afghanistan, Iraq and elsewhere. From 1998 to 2009, 156 (45%) of 343 confirmed cases seen in the UK were in military personnel. CL is a rare disease and requires specialist clinical management because numerous pitfalls exist during diagnosis and treatment. A 19-year-old soldier developed CL on his neck 6 weeks after taking part in jungle warfare training in Belize. However, this was not suspected and the diagnosis was not made from either a skin biopsy or following surgical excision. The travel history and the patient's own photograph prompted retrospective investigations that confirmed this was CL due to Leishmania mexicana. Three months after surgery, the disease recurred locally and was treated appropriately with a good outcome. British military personnel with suspected CL should be referred to the UK Role 4 Military Infectious Diseases & Tropical Medicine Service. Published by the BMJ Publishing Group Limited.

  7. Surgical Excision of Benign Papillomas Diagnosed with Core Biopsy: A Community Hospital Approach

    International Nuclear Information System (INIS)

    Rozentsvayg, Eka; Carver, Kristen; Borkar, Sunita; Mathew, Melvy; Enis, Sean; Friedman, Paul


    Our goal was to assess the value of surgical excision of benign papillomas of the breast diagnosed on percutaneous core biopsy by determining the frequency of upgrade to malignancies and high risk lesions on a final surgical pathology. We reviewed 67 patients who had biopsies yielding benign papilloma and underwent subsequent surgical excision. Surgical pathology of the excised lesions was compared with initial core biopsy pathology results. 54 patients had concordant benign core and excisional pathology. Cancer (ductal carcinoma in situ and invasive ductal carcinoma) was diagnosed in five (7%) patients. Surgery revealed high-risk lesions in 8 (12%) patients, including atypical ductal hyperplasia, atypical lobular hyperplasia, and lobular carcinoma in situ. Cancer and high risk lesions accounted for 13 (19%) upstaging events from benign papilloma diagnosis. Our data suggests that surgical excision is warranted with core pathology of benign papilloma

  8. Frequency and outcomes of biopsy-proven fibroadenomas recommended for surgical excision. (United States)

    Lee, Shimwoo; Mercado, Cecilia L; Cangiarella, Joan F; Chhor, Chloe M


    Our aim was to investigate the outcomes of fibroadenomas recommended for surgical excision due to large size (>2cm) or interval growth. A retrospective review of our institutional radiology database from 2007 to 2015 was performed. We identified 167 biopsy-proven fibroadenomas recommended for surgical consultation. Of these, 75 (45%) cases actually underwent excision, 7 (9%, 95% CI: 4-18%) of which were upgraded to phyllodes tumors upon histopathological examination. Our results support the current recommendation to surgically excise breast lesions diagnosed as fibroadenomas with size >2cm or with interval growth due to the considerable risk of finding phyllodes tumors.

    Conclusions: Although reduction of residual tumor at reexcision is noted with both BCC and even more so with SCC, the rate at which this occurs is not sufficient that a general recommendation to forgo surgical excision can be made.

  10. Phyllodes tumor diagnosed after ultrasound-guided vacuum-assisted excision: should it be followed by surgical excision? (United States)

    Youk, Ji Hyun; Kim, Hana; Kim, Eun-Kyung; Son, Eun Ju; Kim, Min Jung; Kim, Jeong-Ah


    Our aim was to retrospectively evaluate the results of ultrasound (US)-guided vacuum-assisted excision (US-VAE) of phyllodes tumors (PTs). A total of 41 PTs diagnosed at US-VAE followed by surgery (n = 27) or at least 2 y of US monitoring (n = 14) were included. By comparison of US-VAE pathology with surgical histology or follow-up US results, cases were divided into upgraded (malignant) and non-upgraded (benign) groups. These two groups were compared with respect to clinical, procedural and US features. Among 27 surgical cases, 2 (8.7%) of 23 benign PTs were upgraded to malignant PTs. The Breast Imaging Reporting and Data System category was retrospectively assigned as 4a (50%) or 4b (50%) in the upgraded group (n = 2) and 3 (64%) or 4a (36%) in the non-upgraded group (n = 39) (p = 0.018). Residual tumor was observed at the site of US-VAE in 15 of 27 surgical cases and 0 of 14 US follow-up cases (36.6%, 15/41). Given the rates of upgrade to malignancy (8.7%) and residual tumor (36.6%), PTs diagnosed after US-VAE should be surgically excised.

  11. New Surgical Approach for treatment of complex vesicovaginal fistula. Vesical autoplasty; Avances en la cirugia de la fistula vesicovaginal compleja. Autoplastia vesical

    Energy Technology Data Exchange (ETDEWEB)

    Gil-Vernet Vila, J. M.


    Although currently complex ve sico-vaginal fistulae are an uncommon finding, their solution still remains a problem since no effective surgical technique is yet available. We describe a new vesical autoplasty procedure for solving this entity. Once the fistulae has been thoroughly resected and its borders have been unfolded, a graft is obtained from the posterior-superior vesical wall, which is then slid down to the vesical neck thereby covering great extensions where tissue has been lost, even in the presence of low-capacity bladders. This new operation has led to a 100% cure rate of the 42 consecutive cases of vesico-vaginal fistulae operated on and that had undergone repeated surgery using other thecniques. (Author) 8 refs.

    Full Text Available Nicolás Crim, María Elena Forniés-Paz, Rodolfo Monti, Evangelina Espósito, Juan Pablo Maccio, Julio A Urrets-Zavalía Department of Ophthalmology, University Clinic Reina Fabiola, Universidad Católica de Córdoba, Argentina Background: Although frequently underdiagnosed, squamous cell carcinoma is the most commonly observed malignancy of the conjunctiva. Multiple different treatments have been proposed to date. The purpose of this paper is to report our experience in the treatment of In situ carcinoma of the conjunctiva by surgical excision associated with cryotherapy. Methods: Four eyes in four consecutive patients (two men and two women of average age 53.2 (range 39–71 years at the time of diagnosis of ocular surface squamous neoplasia were treated by simple surgical excision and cryotherapy of the resulting surgical bed margins. In all cases, the diagnosis of in situ carcinoma was confirmed histopathologically. Results: On histopathology, the edges of the surgical specimens were free of malignant cells in three of four patients. All patients showed excellent evolution without recurrence. Mean follow-up was 6.5 (range 2–14 years. Conclusion: In situ carcinoma of the conjunctiva may be simply and successfully treated with surgical excision and cryotherapy.

  14. [Management of urachal remnants in children: Is surgical excision mandatory?]. (United States)

    Heuga, B; Mouttalib, S; Bouali, O; Juricic, M; Galinier, P; Abbo, O


    The classical management of urachal remants consists in surgical resection, in order to prevent infections and long term malignancies. However, some reports have recently spread a wait and see management. The aim of our study was to report the results of the surgical management in our center. We conducted a retrospective, monocentric review of all patients managed for urachal remnants from January 2005 to December 2014. Thirty-five patients have been operated during the study period (18 girls and 17 boys). Mean age at surgery was 4,9±4,4 years old. Twenty-seven patients were referred due to symptoms whereas 8 were discovered incidentally (4 by ultrasound scan and 4 during laparoscopy). Among them, 10 were urachal cysts, 15 were urachus sinusa and 10 were patent urachus. Thirty were operated using an open approach and 5 using a laparoscopic approach. Mean length of stay was 3,8±1,7days (1-10) with a mean duration of bladder drainage of 2,5±1 days. No major complications occurred. No abnormal tissue was discovered at the histological analysis. Presentation of urachal remnants is variable but surgical outcomes remain excellent in our experience. When symptoms occur, the surgical decision is easy, but when the diagnosis is incidental, the decision is much more complicated. Official guidelines could ease the decision process and the management of urachal anomalies. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  17. Surgical Approaches to First Branchial Cleft Anomaly Excision: A Case Series

    Directory of Open Access Journals (Sweden)

    Lourdes Quintanilla-Dieck


    Full Text Available Objectives. First branchial cleft anomalies (BCAs constitute a rare entity with variable clinical presentations and anatomic findings. Given the high rate of recurrence with incomplete excision, identification of the entire tract during surgical treatment is of paramount importance. The objectives of this paper were to present five anatomic variations of first BCAs and describe the presentation, evaluation, and surgical approach to each one. Methods. A retrospective case review and literature review were performed. We describe patient characteristics, presentation, evaluation, and surgical approach of five patients with first BCAs. Results. Age at definitive surgical treatment ranged from 8 months to 7 years. Various clinical presentations were encountered, some of which were atypical for first BCAs. All had preoperative imaging demonstrating the tract. Four surgical approaches required a superficial parotidectomy with identification of the facial nerve, one of which revealed an aberrant facial nerve. In one case the tract was found to travel into the angle of the mandible, terminating as a mandibular cyst. This required en bloc excision that included the lateral cortex of the mandible. Conclusions. First BCAs have variable presentations. Complete surgical excision can be challenging. Therefore, careful preoperative planning and the recognition of atypical variants during surgery are essential.

    Yaghoubi, A.R.; Raeesi, K.


    Assessment of surgical pathology of excised heart valves in a referral hospital in Iran in a five years period. This retrospective descriptive study was done from 2002 to 2005 in Rajaie heart center in Tehran, Iran. Surgery and pathology records of patients who underwent valve replacement or repair surgery were reviewed. Of 1563 patients 738 (47.2%) underwent mitral, 565 (36.1%) aortic, and 215 (14%) multivalve operation. Most common pathology of mitral valve was rheumatic (68%), while degenerative calcific pathology was dominant in aortic valve (52%). Rheumatic involvement was 46%, and degenerative pathology was common in tricuspid and pulmonary valves (50% and 67%, respectively). Time trend analysis shows no significant variation in excised valves pathology or pattern from 2002 to 2005 (p=0.112). Rheumatic pathology in excised heart valves is still common in this referral heart center in Iran, and no obvious change in this pattern was found during a 5 years period. (author)

  20. Osteochondroma of the mandibular condyle: surgical excision followed by occlusal stabilization. (United States)

    Yoo, Ji-Yeon; Choi, Byung-Joon; Kwon, Yong-Dae; Lee, Deok-Won; Ohe, Joo-Young; Suh, Joon-Ho


    Osteochondroma of the mandibular condyle in adults can be treated by surgical excision, condylectomy followed by costochondral graft or orthognathic surgery. Such complex treatment plan may not be appropriate for patients with old age, affected with chronic osteochondroma of the condyle. In this clinical report, we present a patient with osteochondroma of the condyle treated by surgical excision. The patient's postoperative occlusion was a contraindication for orthognathic surgery because of the severe abrasion of the teeth and the chronic compensation of the dentition to the deviated mandible. Surgical excision of the lesion was carried out under general anesthesia, and the remaining condylar head was salvaged as much as possible. No graft materials or posthodontic condyle reconstruction was carried out. Because there was no occlusal stop to secure the mandible in a centric relation position of the condyle, a stabilization splint was delivered to position the condyle in a relatively stable position. The stability of the condyle position was evaluated by follow-up cone beam computed tomographic scans of the pathologic and the contralateral condyle, along with clinical factors such as occlusal contact points and mandible movements assayed by ARCUSdigma (KaVo). After significant condylar position was achieved, full prosthodontic reconstruction was performed to both the patient's and the dentist's satisfaction.

  2. Olfactory groove meningioma: discussion of clinical presentation and surgical outcomes following excision via the subcranial approach. (United States)

    Pepper, Jon-Paul; Hecht, Sarah L; Gebarski, Stephen S; Lin, Erin M; Sullivan, Stephen E; Marentette, Lawrence J


    To describe surgical outcomes and radiographic features of olfactory groove meningiomas treated by excision through the subcranial approach. Special emphasis is placed on paranasal sinus and orbit involvement. Retrospective review of a series of patients. Nineteen patients underwent excision of olfactory groove meningioma (OGM) via the transglabellar/subcranial approach between December 1995 and November 2009. Nine patients had previously undergone prior resection at outside institutions, and four had prior radiotherapy in addition to a prior excision. Transglabellar/subcranial surgical approach to the anterior skull base was performed. Tumor histology included three World Health Organization (WHO) grade III lesions, one WHO grade II lesion, and 15 WHO grade I lesions. Fourteen patients had evidence of extension into the paranasal sinuses, with the ethmoid sinus being most commonly involved. Kaplan-Meier estimates of mean overall and disease-free survival were 121.45 months and 93.03 months, respectively. The mean follow-up interval was 41.0 months, and at the time of data analysis three patients had recurrent tumors. Seven (36.8%) patients experienced a major complication in the perioperative period; there were no perioperative mortalities. Orbit invasion was observed in four patients, with optic nerve impingement in 11 patients. Of these, three patients had long-term diplopia. No patients experienced worsening of preoperative visual acuity. Olfactory groove meningiomas demonstrate a propensity to spread into the paranasal sinuses, particularly in recurrent cases. Given a tendency for infiltrative recurrence along the skull base, this disease represents an important area of collaboration between neurosurgery and otolaryngology. The subcranial approach offers excellent surgical access for excision, particularly for recurrences that involve the paranasal sinuses and optic apparatus.

  3. Genotypic and antimicrobial characterisation of Propionibacterium acnes isolates from surgically excised lumbar disc herniations

    DEFF Research Database (Denmark)

    Rollason, Jess; McDowell, Andrew; Albert, Hanne B


    The anaerobic skin commensal Propionibacterium acnes is an underestimated cause of human infections and clinical conditions. Previous studies have suggested a role for the bacterium in lumbar disc herniation and infection. To further investigate this, five biopsy samples were surgically excised...... from each of 64 patients with lumbar disc herniation. P. acnes and other bacteria were detected by anaerobic culture, followed by biochemical and PCR-based identification. In total, 24/64 (38%) patients had evidence of P. acnes in their excised herniated disc tissue. Using recA and mAb typing methods...... isolate collection (63%) suggests that the role of P. acnes in lumbar disc herniation should not be readily dismissed....

  4. Recurrent vulvar carcinoma: complex surgical treatment via perineal excision and reconstruction with musculocutaneous flap

    Directory of Open Access Journals (Sweden)

    Dragoș Popa


    Full Text Available Vulvar cancer is a malignant disease having a low frequency and with well-established surgical and oncological treatments based on the stage of the disease. The most important therapeutic problem encountered is represented by cases of perineal local regional recurrence, which are common in patients with large primary tumors and can occur even if the margins of the resection had no tumoral invasion. We present a case study of a 64-year-old patient diagnosed one year ago with squamous vulvar carcinoma (G3 for which a vulvectomy was performed after neoadjuvant radiotherapy. The patient later developed local recurrence with invasion of the anal sphincter, creating a delicate problem regarding a surgical approach. The size and the extent of the recurrent tumor required a complex surgical intervention using a mixed surgical team of general surgeons and plastic surgeons. Surgical intervention with a large excision of the recurrent cancer along with amputation of the inferior rectum via perineal route, and creation of a left iliac anus was performed. The perineal defect was covered via a musculocutaneous flap using the gracilis muscle. The immediate post-operative evolution was favorable.

  5. Recurrent Scedosporium apiospermum mycetoma successfully treated by surgical excision and voriconazole

    Directory of Open Access Journals (Sweden)

    Chi-Hsuan Chiang


    Full Text Available Scedosporium apiospermum is an emerging opportunistic fungus that can cause localized infection in healthy hosts or severe disseminated disease in immunocompromised hosts. Most cases are reported in Western Europe, Australia, and North America. We report a 52-year-old immunocompetent Taiwanese woman who presented with a 6-year history of recurrent asymptomatic papulonodular lesions on her right foot after minor trauma. Deep fungal infection caused by Scedosporium sp. was diagnosed after a skin biopsy with fungal culture of the skin specimen. She underwent two surgical excisions, each followed by a 4-month course of oral itraconazole and intralesional injections of amphotericin B as well, but similar lesions recurred at the same location 1 year later. She had another surgical excision and the pathological findings showed mycetoma. The fungus was identified as S. apiospermum by PCR assay of fungal culture specimen using the internal transcriber spacers (ITS1, similarity 99.4%; ITS2, similarity 100% and the D1–D2 (similarity 99.0% regions of the ribosomal operon. After 4 months of oral voriconazole (400 mg/day, no recurrence was noted in the subsequent 2 years.

  6. Lateral pedicle graft for repair of residual gingival defect following complete surgical excision of a pyogenic granuloma


    Awadhesh Kumar Singh; Abhisek Gautam


    The pyogenic granuloma, one of the gingival lesions, has recurrence rate of 16%. To minimize the recurrence rate, it must be completely excised. Complete surgical excision can result in residual gingival defect. McCrea repaired residual gingival defect by subepithelial connective tissue graft with lateral mucogingival pedicle flap, and Choudhary et al. managed residual gingival defect by subepithelial connective tissue graft only. The aim of this case report was to use lateral pedicle graft f...

  7. Sinotomy technique versus surgical excision with primary closure technique in pilonidal sinus disease

    Directory of Open Access Journals (Sweden)

    Seyfi Emir


    Full Text Available Pilonidal disease is a common chronic disorder mainly seen in the sacrococcygeal region, especially in young males. Many surgical treatment modalities have been suggested, but an ideal and widely accepted treatment has yet to be established. The aim of this study was to compare quality of life of patients treated with the sinotomy technique with quality of life of patients treated with surgical excision plus primary closure technique by means of quality of life questionnaire. The data of patients who had been treated for pilonidal sinus in our clinic from September 2010 to June 2012 were analyzed retrospectively. Forty patients were treated with sinotomy technique and 40 patients were treated with surgical excision plus primary closure technique. Time to return to work and to time to complete wound healing were evaluated. All patients were asked to fill the questionnaire after complete healing occurred. Postoperative complications were bleeding in 2.5%, infection in 3.75% and fever in 2.5% patients. There were no significant differences between the two groups in terms of complete healing (p=0.1 and sport times (p=0.1. There were significant differences between the groups in terms of length of hospital stay (p≤0.001, time off work (p≤0.001,times to sitting on toilet and walking without pain (p=0.002 and p≤0.001,respectively. The mean postoperative VAS scores were 5.2±3.2 and 2.8±2.2, respectively (p=0.02. The technique of sinotomy with good wound and surrounding skin care seems to be an ideal approach with high chance of cure. The patients returned to their routine in a short period of time.

  8. [Conservative surgical treatment of renal carcinoma. Personal experience with 29 surgical excisions of tumors]. (United States)

    Villani, U; Pastorello, M


    From 1980 to 1988, elective conservative surgery (tumorectomy by enucleo-resection) was performed for renal cell carcinoma at stage I in 29 patients. An accurate preoperative renal investigation was carried out to identify the exact extension of the tumor and to study all the parenchimal situation, through IVP, ultrasound, CT scanning and, particularly, conventional selective angiography. The operative technique employed was: lymphadenectomy, peri-pararenal fat extirpation, in situ tumor enucleation by circular incision of the renal capsule and blunt dissection of the renal parenchyma with 2 cm safety margin to the tumor; multiple biopsies in the "bed" of resection for histopathologic peroperative evaluation; careful examination of the pseudocapsule and surrounding renal tissue; hemostasis. Follow-up was 10-113 months (mean 40,34 months). 2 of 29 patients died for progression of disease (at 52nd and 16yh month from surgery, 2/29 died for non-neoplastic reasons; 25/29 pts are living without local recurrences or distant metastases. In the same period (1980-1988), radical nephrectomy was performed for renal tumors at stage I in 34 patients. In an average observation period of 49,67 months, 2/34 patients died for progression of disease; 3/34 pts died for non-neoplastic reasons. 1/34 patient is living with pulmonar metastases and 28/34 are living without evidence of cancer. From this study we have got the conclusion that elective renal-sparing excision of the tumor (with macro-micro examination of the abscission surfaces) should be considered as a curative treatment in the case of low stage single tumors smaller than 7 cm, peripherally located in renal cortex, with unbroken pseudocapsule.

  9. Lateral pedicle graft for repair of residual gingival defect following complete surgical excision of a pyogenic granuloma

    Directory of Open Access Journals (Sweden)

    Awadhesh Kumar Singh


    Full Text Available The pyogenic granuloma, one of the gingival lesions, has recurrence rate of 16%. To minimize the recurrence rate, it must be completely excised. Complete surgical excision can result in residual gingival defect. McCrea repaired residual gingival defect by subepithelial connective tissue graft with lateral mucogingival pedicle flap, and Choudhary et al. managed residual gingival defect by subepithelial connective tissue graft only. The aim of this case report was to use lateral pedicle graft for repair of residual gingival defect following complete surgical excision of a pyogenic granuloma. A patient with pyogenic granuloma on labial surface of maxillary central incisors was treated by complete surgical excision, and residual gingival defect was repaired by lateral pedicle graft. A lateral pedicle graft was raised as full-thickness up to mucogingival line and partial-thickness apical to mucogingival line from the left side of residual gingival defect. After 6 months, no recurrence was noticed. Thus, lateral pedicle graft can be potentially used for repair of residual gingival defect following complete surgical excision of a pyogenic granuloma.

  10. Surgical excision for recurrent herpes simplex virus 2 (HSV-2) anogenital infection in a patient with human immunodeficiency virus (HIV). (United States)

    Arinze, Folasade; Shaver, Aaron; Raffanti, Stephen


    Recurrent anogenital herpes simplex virus infections are common in patients with human immunodeficiency virus (HIV), of whom approximately 5% develop resistance to acyclovir. We present a case of a 49-year-old man with HIV who had an 8-year history of recurrent left inguinal herpes simplex virus type 2 ulcerations. He initially responded to oral acyclovir, but developed resistance to acyclovir and eventually foscarnet. The lesion progressed to a large hypertrophic mass that required surgical excision, which led to resolution without recurrences. Our case highlights the importance of surgical excision as a treatment option in refractory herpes simplex virus anogenital infections.

  12. Measurement of the uniaxial elasticity of oral mucosa in vivo after CO2-laser evaporation and surgical excision. (United States)

    Roodenburg, J L; ten Bosch, J J; Borsboom, P C


    The stress-strain relation of oral mucosa of dogs was measured before and 6 weeks after surgical removal of mucosa. Both CO2-laser evaporation and excision were employed. Measurements were done with a miniature tensile tester, especially developed for this purpose. The load-strain ratio of the healed mucosa was proportional to the histologically determined thickness of the healed epithelium and scar tissue together. Laser evaporation caused a 75% increase, excision almost a threefold increase of the load-strain ratio compared with untreated tissue.

    Tanaydin, V; Beugels, J; Piatkowski, A; Colla, C; van den Kerckhove, E; Hugenholtz, G C G; van der Hulst, R R


    Mechanical pressure is increasingly applied as a means to prevent or treat keloid scars. The aim of this study is to analyze the long-term efficacy of our custom-molded pressure-adjustable earclips to prevent keloid recurrence after surgical excision. Using our custom-molded earclip, 88 patients who had undergone ear surgery for keloid scars were treated for 12 h a day for 6-18 months. The mean follow-up was 6.5 years. The primary outcome was the recurrence of keloids with patient satisfaction being the secondary outcome as assessed by Patient and Observer Scale (POSAS). Keloid scars did not recur in 70.5% of treated patients. The Fitzpatrick scale, which classifies human skin by type, was significantly different between the recurrence and nonrecurrence group. Differences in other patient characteristics were not found between both groups. All parameters mentioned in the POSAS patient scale drastically improved after therapy. There were no severe side effects observed after the therapy. Our pressure-adjustable earclip model is an effective tool in the prevention of ear keloid recurrence and is associated with high patient satisfaction. Its benefits should prompt further studies on its value as an adjuvant therapy to surgery in keloid treatment. Level III on the Evidence Rating Scale for Therapeutic Studies.

    Khalil Ullah; Badsha, S.; Khan, A.; Kiani, M.R.; Ahmed, S.A.


    Objective: To examine the prevalence, age, sex and topographical distribution of the rheumatic heart diseases and its morphology. Design: A cross sectional descriptive study. Place and Duration of Study: Pathology Department, Army Medical College, Rawalpindi between 1981-1990. Patients and Methods: Five hundred and twenty six surgically excised cardiac valves and biopsies were studied in the laboratory in the light of clinical data. Results: Carditis constituted 87.4 % of the cardiac valvular disease with 23.5% active and 71% healed rheumatic lesions. About 5.5% had morphological appearances consistent with RHD. The lesions affected mitral valves (37.0%), aortic valve (22.1%), mitral and aortic valves together (21.0%) and atrial appendages (19.0%). Presentation was mostly as mitral stenosis either isolated (49.2% ) or combined (31.0%), aortic stenosis (11.7% ) and aortic incompetence with regurgitation (7.3%). Conclusion: Rheumatic carditis constitutes a significant proportion of cardiac valvular disease and affects comparatively younger age, with slight male preponderance and primarily affects mitral valve.

    To correlate the mammographic and ultrasonographic findings with the pathologic results in women undergoing hormone replacement therapy (HRT), and to determine the characteristic clinical, mammographic or histologic findings of breast cancer in these patients. Twenty-five breast lesions in 25 patients aged 44-65 (mean, 55.5) years undergoing HRT were surgically removed due to abnormal mammographic findings or the presence of palpable masses. Mammograms in all patients and ultrasonograms in 23 were retrospectively analyzed in terms of the shape and margin of the mass, and microcalcifications, and the imaging findings were correlated with the pathologic results. As a control group, 45 cancer patients not undergoing HRT were selected. Using the student t test, detection methods, tumor size, mammographic findings, and the proportion of intraductal cancers were compared between to two groups. Surgical excision revealed ten benign lesions (four fibroadenomas and six cases of fibrocystic change) and 15 cancers (three intraductal and twelve invasive ductal cancers). Abnormal findings at mammography were a mass in 16 cases, clustered microcalcifications in seven, and a mass with microcalcifications in two. Mammography showed that all four circumscribed masses were benign. Five of seven ill-defined masses (71%) and all six spiculated masses were malignant. Three of seven cases (43%) with microcalcifications, and both with a mass and microcalcification, were malignant. In two cases in which ultrasonography revealed cystic lesions, histologic examination showed that fibrocystic change had occurred. Compared to non-HRT-related cancers, HRT-related cancers were more often detected by mammography (60% vs 16%; p<0.001), smaller (17 mm vs 24 mm, p<0.01), showed microcalcification only (20% vs 13%; p<0.05), and were intraductal (20% vs 7%; p<0.01). In patients with HRT, mammographic findings of an ill-defined or spiculated mass, or one with microcalcifications, were associated with

  16. High-Risk Breast Lesions: A Machine Learning Model to Predict Pathologic Upgrade and Reduce Unnecessary Surgical Excision. (United States)

    Bahl, Manisha; Barzilay, Regina; Yedidia, Adam B; Locascio, Nicholas J; Yu, Lili; Lehman, Constance D


    Purpose To develop a machine learning model that allows high-risk breast lesions (HRLs) diagnosed with image-guided needle biopsy that require surgical excision to be distinguished from HRLs that are at low risk for upgrade to cancer at surgery and thus could be surveilled. Materials and Methods Consecutive patients with biopsy-proven HRLs who underwent surgery or at least 2 years of imaging follow-up from June 2006 to April 2015 were identified. A random forest machine learning model was developed to identify HRLs at low risk for upgrade to cancer. Traditional features such as age and HRL histologic results were used in the model, as were text features from the biopsy pathologic report. Results One thousand six HRLs were identified, with a cancer upgrade rate of 11.4% (115 of 1006). A machine learning random forest model was developed with 671 HRLs and tested with an independent set of 335 HRLs. Among the most important traditional features were age and HRL histologic results (eg, atypical ductal hyperplasia). An important text feature from the pathologic reports was "severely atypical." Instead of surgical excision of all HRLs, if those categorized with the model to be at low risk for upgrade were surveilled and the remainder were excised, then 97.4% (37 of 38) of malignancies would have been diagnosed at surgery, and 30.6% (91 of 297) of surgeries of benign lesions could have been avoided. Conclusion This study provides proof of concept that a machine learning model can be applied to predict the risk of upgrade of HRLs to cancer. Use of this model could decrease unnecessary surgery by nearly one-third and could help guide clinical decision making with regard to surveillance versus surgical excision of HRLs. © RSNA, 2017.

  17. Serum levels of renin, angiotensin-converting enzyme and angiotensin II in patients treated by surgical excision, propranolol and captopril for problematic proliferating infantile haemangioma. (United States)

    Sulzberger, L; Baillie, R; Itinteang, T; de Jong, S; Marsh, R; Leadbitter, P; Tan, S T


    The role of the renin-angiotensin system (RAS) in the biology of infantile haemangioma (IH) and its accelerated involution induced by β-blockers was first proposed in 2010. This led to the first clinical trial in 2012 using low-dose captopril, an angiotensin-converting enzyme (ACE) inhibitor, demonstrating a similar response in these tumours. This study aimed to compare serial serum levels of the components of the RAS in patients before and after surgical excision, propranolol or captopril treatment for problematic proliferating IH. Patients with problematic proliferating IH underwent measurements of serum levels of plasma renin activity (PRA), ACE and angiotensin II (ATII) before, and 1-2 and 6 months following surgical excision, propranolol or captopril treatment. This study included 27 patients undergoing surgical excision (n = 8), propranolol (n = 11) and captopril (n = 8) treatment. Treatment with either surgical excision or propranolol resulted in significant decrease in the mean levels of PRA. Surgical excision or captopril treatment led to significant decline in the mean levels of ATII. All three treatment modalities had no significant effect on the mean levels of ACE. This study demonstrates the effect of surgical excision, propranolol and captopril treatment in lowering the levels of PRA and ATII, but not ACE, supporting a mechanistic role for the RAS in the biology of IH.

  18. Xylazine-ketamine immobilization and propofol anesthesia for surgical excision of sebaceous adenoma in a jaguar (Panthera onca

    Directory of Open Access Journals (Sweden)

    M. Bharathidasan


    Full Text Available Aim: A captive male jaguar (Panthera onca was anaesthetized for surgical excision of a tumor at the left belly fold under xylazine-ketamine immobilization and propofol anesthesia. The objective was to assess the dose of xylazine and ketamine required to abolish ear flick reflex for safe approach when the jaguar was under chemical immobilization and efficacy of propofol induced anesthesia. Materials and Methods: A male jaguar (P. onca aged 14 years and weighing approximately 90 kg was subjected to chemical immobilization using a combination of xylazine and ketamine using a blow pipe. The jaguar was approached after the absence of ear flick reflex and transported to zoo Operation Theater. Propofol was administered intravenously to induce and maintain anesthesia. The tumor was excised using thermocautery and subjected to histopathology. Results: Ear flick reflex was stimulated at 5 and 10 min after immobilization and observed shaking of head and movement of fore limb following administration of xylazine and ketamine. Dose of xylazine and ketamine required for chemical immobilization, characterized by absence of ear flick reflex was 1.0 and 3.5 mg/kg body weight respectively, and was achieved in 13 min. The surgical plane of anesthesia was maintained for 11 min following administration of propofol at a dose of 2 mg/kg body weight intravenously. The jaguar recovered in 41 min following surgery. The excised tumor was confirmed as sebaceous adenoma on histopathological examination. The animal recovered uneventfully, and no recurrence of the tumor was noticed in 3 months follow-up period. Conclusion: The total dose xylazine and ketamine required for chemical immobilization with absence of ear flick reflex was 1.0 and 3.5 mg/kg body weight respectively. Further, administration of propofol intravenously, at a dose of 2 mg/kg maintained anesthesia for 11 min. Histopathological examination of the excised tumor at the belly fold was confirmed as sebaceous

  20. [Local excision of rectal tumors. Indications, preoperative diagnosis, surgical technique and results]. (United States)

    Heintz, A; Braunstein, S; Menke, H


    Between January 1986 and October 1991 255 patients with rectal tumors were treated by local excision. In 239 patients local excision was performed by transanal endoscopic microsurgery, 16 tumors were removed with the retractor developed by Parks. Operative mortality was 1% in 189 local removed adenomas, complications were observed in two patients (2.1%), local recurrences in seven patients (3.7%). 66 rectal carcinomas were treated by local excision (operative mortality 1%, complication rate 3%). In one of 28 local excised "low risk" T1-carcinomas a recurrence was observed. Five of eleven local treated patients with "high risk" tumors developed a recurrence. Endosonography was of utmost importance in preoperative staging of rectal tumors. Between June 1987 and October 1991 204 patients with rectal tumors (92 sessile adenomas, 30 T1-carcinomas and 82 advanced carcinomas) were examined preoperatively by endosonography. The diagnosis of an adenoma or a T1-carcinoma was made with a sensitivity of 0.9, although no differentiation was possible between adenomas and T1-carcinomas. Results of digital examination were comparable to endosonography, under condition that digital examination was complete. Insufficient information was obtained from the endosonographic detection of lymph-node metastatic spread.

  1. Surgical therapy of Peyronie's disease by partial plaque excision and grafting with collagen fleece: feasibility study of a new technique. (United States)

    Hatzichristodoulou, G; Gschwend, J E; Lahme, S


    Surgery is gold-standard for correction of Peyronie's curvature. Grafting is preferred in advanced deviations. We present our novel surgical technique and early results of grafting with collagen fleece. Patients with stable Peyronie's disease (PD) were included. Grafting was performed by a ready-to-use collagen fleece coated with tissue sealant (TachoSil, Nycomed, Konstanz, Germany), following partial plaque excision/incision. Results of correction were documented by artificial erection. In all, n=70 consecutive patients underwent surgery. Mean patient age was 56.4 years (range: 33-72); 88.6% of patients had dorsal deviation, 11.4% lateral or ventral deviation. Grafting after partial plaque excision was performed in 61 patients (87.1%), after plaque incision in 2 (2.9%) patients. In the former patients, mean operative time was 94.2 min (range: 65-165). Totally straightness was achieved in 83.6%. Three patients required surgical drainage because of subcutaneous haematoma formation. After mean early follow-up of 5.2 days (range: 2-15), glans sensation was normal in 56 patients (91.8%). Seven patients (10.0%) underwent Nesbit procedure alone. Grafting by collagen fleece in PD is feasible and promising. Major advantages are decreased operative times and easy application. Moreover, an additional haemostatic effect is provided. However, long-term clinical outcomes are necessary to confirm these encouraging findings.

    Purpose Breast implant–associated anaplastic large-cell lymphoma (BI-ALCL) is a rare type of T-cell lymphoma that arises around breast implants. The optimal management of this disease has not been established. The goal of this study is to evaluate the efficacy of different therapies used in patients with BI-ALCL to determine an optimal treatment approach. Patients and Methods In this study, we applied strict criteria to pathologic findings, assessed therapies used, and conducted a clinical follow-up of 87 patients with BI-ALCL, including 50 previously reported in the literature and 37 unreported. A Prentice, Williams, and Peterson model was used to assess the rate of events for each therapeutic intervention. Results The median and mean follow-up times were 45 and 30 months, respectively (range, 3 to 217 months). The median overall survival (OS) time after diagnosis of BI-ALCL was 13 years, and the OS rate was 93% and 89% at 3 and 5 years, respectively. Patients with lymphoma confined by the fibrous capsule surrounding the implant had better event-free survival (EFS) and OS than did patients with lymphoma that had spread beyond the capsule (P = .03). Patients who underwent a complete surgical excision that consisted of total capsulectomy with breast implant removal had better OS (P = .022) and EFS (P = .014) than did patients who received partial capsulectomy, systemic chemotherapy, or radiation therapy. Conclusion Surgical management with complete surgical excision is essential to achieve optimal EFS in patients with BI-ALCL. PMID:26628470

  4. Surgical planning for microsurgical excision of cerebral arterio-venous malformations using virtual reality technology. (United States)

    Ng, Ivan; Hwang, Peter Y K; Kumar, Dinesh; Lee, Cheng Kiang; Kockro, Ralf A; Sitoh, Y Y


    To evaluate the feasibility of surgical planning using a virtual reality platform workstation in the treatment of cerebral arterio-venous malformations (AVMs) Patient-specific data of multiple imaging modalities were co-registered, fused and displayed as a 3D stereoscopic object on the Dextroscope, a virtual reality surgical planning platform. This system allows for manipulation of 3D data and for the user to evaluate and appreciate the angio-architecture of the nidus with regards to position and spatial relationships of critical feeders and draining veins. We evaluated the ability of the Dextroscope to influence surgical planning by providing a better understanding of the angio-architecture as well as its impact on the surgeon's pre- and intra-operative confidence and ability to tackle these lesions. Twenty four patients were studied. The mean age was 29.65 years. Following pre-surgical planning on the Dextroscope, 23 patients underwent microsurgical resection after pre-surgical virtual reality planning, during which all had documented complete resection of the AVM. Planning on the virtual reality platform allowed for identification of critical feeders and draining vessels in all patients. The appreciation of the complex patient specific angio-architecture to establish a surgical plan was found to be invaluable in the conduct of the procedure and was found to enhance the surgeon's confidence significantly. Surgical planning of resection of an AVM with a virtual reality system allowed detailed and comprehensive analysis of 3D multi-modality imaging data and, in our experience, proved very helpful in establishing a good surgical strategy, enhancing intra-operative spatial orientation and increasing surgeon's confidence.

  5. New minimally invasive surgical approach for excision of left atrial myxoma. (United States)

    Spadaccio, Cristiano; Elkasrawy, Karim; Sutherland, Fraser W H


    A novel minimally invasive technique for left atrial myxoma surgery involving a combination of mini-sternotomy and restricted left atrial dome incision is described. Surgery is performed through a mini-J sternotomy at third intercostal space and a standard aorto-right atrial cannulation. Exposure of cardiac mass is obtained by a restricted incision of the left atrial dome which provides excellent view of the entire interatrial septum. Base of the tumor base is clearly visualized making the en-bloc excision extremely easy. Three cases were successfully treated with this technique and discharged with mild analgesic requirements. The limited invasiveness and the avoidance of wide incisions in the heart chambers are points of strength of this approach and allow to overcome the limitations of the currently used interatrial groove or transeptal approaches, as scarce visualization of the septum and site of tumor attachment and risk of conduction disturbances or traumatic injury to the mass.

  7. Surgical excision for mediastinal synovial sarcoma with limited response to chemoradiotherapy. (United States)

    Kara, H Volkan; Javidfar, Jeffrey; D'Amico, Thomas A


    Primary synovial sarcoma of the mediastinum is an exceedingly rare neoplasm. We describe a 31-year-old woman who had an incidental diagnosis of mediastinal mass. Histopathology and immunohistochemistry analysis confirmed the diagnosis of primary mediastinal synovial sarcoma. The patient underwent concurrent chemotherapy and radiotherapy, with minimal response radiologically. Resection was subsequently performed, with negative margins. The histopathologic examination revealed the diagnosis with a limited pathologic response. Because of the rarity of primary mediastinal synovial sarcoma, the optimal therapy is still unclear. We report this case of induction therapy followed by en bloc surgical resection. Copyright © 2014 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

  8. Radical treatment of extensive nevoid hyperkeratosis of the areola and breast with surgical excision after mild response to topical agents: A case report

    Directory of Open Access Journals (Sweden)

    Ilaria Tocco-Tussardi, MD


    Conclusion: Indications for surgical treatment of NHNA can be: unsatisfying response to topical agents; young patients who want to restore the aesthetic appearance of the breast; and patients with concomitant indication for corrective surgery of the breast. Advantages are: predictable time of healing; predictable final result; radical excision of the affected tissue; and possibility of histologic analysis of the whole areola. In rare cases of lesions extending to the breast, preliminary treatment with topical agents can limit the extent of excision. Management and treatment should always be tailor-made for each individual case.

  9. Use of adjuvant carboplatin for treatment of dogs with oral malignant melanoma following surgical excision. (United States)

    Dank, G; Rassnick, K M; Sokolovsky, Y; Garrett, L D; Post, G S; Kitchell, B E; Sellon, R K; Kleiter, M; Northrup, N; Segev, G


    Melanoma is the most common oral malignancy in dogs. This retrospective study evaluated adjuvant carboplatin chemotherapy (with or without radiation therapy) in 17 dogs with malignant oral melanoma following surgical resection. The median dosage and number of doses of carboplatin administered to the 17 dogs was 300 mg m(-2) (range, 150-300 mg m(-2)) and 4 (range, 2-11), respectively. The overall median progression-free survival for all dogs was 259 days [95% confidence interval (CI95), 119-399 days]. The first progression-free survival event was local recurrence in seven dogs (41%) and metastases in seven dogs (41%). The median overall survival for all dogs was 440 days (CI95, 247-633 days). The tumour was the cause of death in 10 dogs (59%). On the basis of this study, systemic therapy with carboplatin may be an appropriate adjunct to local treatment for canine malignant melanoma, although future prospective controlled studies are needed to compare treatment modalities for this aggressive neoplasia. © 2012 John Wiley & Sons Ltd.

  10. Preoperative Embolization Reduces the Risk of Cathecolamines Release at the Time of Surgical Excision of Large Pelvic Extra-Adrenal Sympathetic Paraganglioma

    Directory of Open Access Journals (Sweden)

    Nicola Di Daniele


    Full Text Available A 30-year-old woman with severe hypertension was admitted to the hospital with a history of headache, palpitations, and diaphoresis following sexual intercourse. Twenty-four hour urinary excretion of free catecholamines and metabolites was markedly increased as was serum chromogranin A. Computed tomography scan revealed a large mass in the left adnex site and magnetic resonance imaging confirmed the computer tomography finding, suggesting the presence of extra-adrenal sympathetic paraganglioma. I-metaiodobenzyl guanidine scintigram revealed an increased uptake in the same area. Transcatheter arterial embolization of the mass resulted in marked decreases in blood pressure and urinary excretion of free catecholamines and metabolites. Surgical excision of the mass was then accomplished without complication. Preoperative embolization is a useful and safe procedure which may reduce the risk of catecholamines release at the time of surgical excision in large pelvic extra-adrenal sympathetic paraganglioma.

  12. Results of surgical excision and evaluation of factors associated with survival time in dogs with lingual neoplasia: 97 cases (1995-2008). (United States)

    Culp, William T N; Ehrhart, Nicole; Withrow, Stephen J; Rebhun, Robert B; Boston, Sarah; Buracco, Paolo; Reiter, Alexander M; Schallberger, Sandra P; Aldridge, Charles F; Kent, Michael S; Mayhew, Philipp D; Brown, Dorothy C


    To describe the clinical characteristics, treatments, outcomes, and factors associated with survival time in a cohort of dogs with lingual neoplasia that underwent surgical excision. Retrospective case series. Animals-97 client-owned dogs. Medical records of dogs with a lingual tumor examined between 1995 and 2008 were reviewed. Records were included if a lingual tumor was confirmed by histologic examination and surgical excision of the mass was attempted. Data were recorded and analyzed to identify prognostic factors. Clinical signs were mostly related to the oral cavity. For 93 dogs, marginal excision, subtotal glossectomy, and near-total glossectomy were performed in 35 (38%), 55 (59%), and 3 (3%), respectively. Surgery-related complications were rare, but 27 (28%) dogs had tumor recurrence. The most common histopathologic diagnoses for the 97 dogs were squamous cell carcinoma (31 [32%]) and malignant melanoma (29 [30%]). Eighteen (19%) dogs developed metastatic disease, and the overall median survival time was 483 days. Median survival time was 216 days for dogs with squamous cell carcinoma and 241 days for dogs with malignant melanoma. Dogs with lingual tumors ≥ 2 cm in diameter at diagnosis had a significantly shorter survival time than did dogs with tumors melanoma predominate. A thorough physical examination to identify lingual tumors at an early stage and surgical treatment after tumor identification are recommended because tumor size significantly affected survival time.

  13. Understanding the surgical pitfalls in total mesorectal excision: Investigating the histology of the perirectal fascia and the pelvic autonomic nerves. (United States)

    Kraima, A C; West, N P; Treanor, D; Magee, D R; Bleys, R L A W; Rutten, H J T; van de Velde, C J H; Quirke, P; DeRuiter, M C


    Excellent understanding of fasciae and nerves surrounding the rectum is necessary for total mesorectal excision (TME). However, fasciae anterolateral to the rectum and surrounding the low rectum are still poorly understood. We studied the perirectal fascia enfolding the extraperitoneally located part of the rectum in en-bloc cadaveric specimens and the University Medical Center Utrecht (UMCU) pelvic dataset, and describe implications for TME. Four donated human adult cadaveric specimens (two males, two females) were obtained through the Leeds GIFT Research Tissue Programme. Paraffin-embedded blocks were produced and serially sectioned at 50 and 250 μm intervals. Whole mount sections were stained with haematoxylin & eosin, Masson's trichrome and Millers' elastin. Additionally, the UMCU pelvic dataset including digitalised cryosections of a female pelvis in three axes was studied. The mid and lower rectum were surrounded by a multi-layered perirectal fascia, of which the mesorectal fascia (MRF) and parietal fascia bordered the 'holy plane'. There was no extra constant fascia forming a potential surgical plane. Nerves ran laterally to the MRF. More caudally, the mesorectal fat strongly reduced and the MRF approached the rectal muscularis propria. The MRF had a variable appearance in terms of thickness and completeness, most prominently at the anterolateral lower rectum. Dissection onto the MRF allows nerve preservation in TME. Rectal surgeons are challenged in doing so as the MRF varies in thickness and shows gaps, most prominently at the anterolateral lower rectum. At this site, the risk of entering the mesorectum is great and may result in an incomplete specimen. Copyright © 2015 Elsevier Ltd. All rights reserved.

  14. Incidence of Incomplete Excision in Surgically Treated Cutaneous Squamous Cell Carcinoma and Identification of the Related Risk Factors

    Directory of Open Access Journals (Sweden)

    Sara Sabouri Rad


    Full Text Available Squamous cell carcinoma (SCC is the second most common type of skin cancer with potential risks for metastasis and recurrence if left untreated or incompletely excised. This case series study was designed to determine the frequency of incompletely excised SCCs and the related risk factors. A total of 273 SCCs (253 patients excised in Razi dermatology hospital of Tehran from 2006-2008, were evaluated and were analyzed by Chi-square or t-test. The incidence of incomplete excision was 17.58 % and deep margin involvement was observed in 73% of lesions. Risk factors associated with incomplete excision of SCCs were being female, location of the tumors (in particular the lesions on lateral canthus, upper lip, foot, forehead, cheek, neck, nose and ear, large lesions and grafting method of repair. There was no statistically significant difference for the age, degree of histological differentiation, childhood history of radiotherapy for tinea capitis and the type of anesthesia. More care should be taken for high risk SCCs as complete excision avoids potential risk of recurrence and metastasis.

    Basal Cell Carcinomas (BCCs) are common cutaneous neoplasms that mainly affect fair-skinned subjects, in sun-exposed areas of the body. The treatment of choice of BCCs is represented by surgical excision and different techniques are available, in order to allow the complete eradication of the tumour with the best cosmetic results. In this paper we describe the Surgical Excision with Stained Margin Technique (SMET) and we report its efficacy for the treatment of BCCs of the head and neck region. We retrospectively studied 177 BCCs of the head and neck region treated by SMET: a surgical technique in which each specimen is cut vertically like a bread-loaf in multiple sections of 1 mm thickness, after marking peripheral margins. We observed an overall recurrence rate of 4.5% after SMET (mean follow-up=26 months), with higher rate in aggressive subtypes (p=0.04). BCCs located in high-risk sites and those previously undergone to other non-radical therapies required 2 or more procedures (p=0.008 and 0.002, respectively), while no correlation was observed between the number of SMET procedures and recurrence rate. In our experience, since low recurrence rate was obtained by SMET, we suggest that it may be taken into consideration as surgical option for BCCs of the head and neck region.

E-mail: The reconstructive surgery has been growing in veterinary medicine, whether in reconstruction tissue caused by trauma or even when there is an extensive tumor resection. This report aims to discuss about a female dog, assisted at the Teaching Hospital of an Educational Institution, which had an ulcerated nodule in the lateral portion of nasal flow plan, with suggestive diagnosis of malignant melanoma, concluded through cytology and referred for surgery. After resection of the tumor, the incision of skin and subcutaneous divulsion for production pedicle flap of advance. After surgery, it was applied with a padded bandage and gauze sheath on the face of the animal. During both the post-operative immediate period and in the following days the retail tissue showed rosy and healthy, with no sign of necrosis or dehiscence. The animal was observed until the day 30 after surgery, where there was local hair growth and good aesthetic appearance, which leads to the conclusion that the pedicle flap advance was an appropriate choice in this case, solving the matter about the animal’s health and looking from the owner’s point of view.

    To compare the efficacy of carbon dioxide (CO/sub 2/) laser with cutting diathermy as a cutting device in surgical excision of early carcinoma tongue. Study Design: Experimental study. Place and Duration of Study: Combined Military Hospital (CMH), Rawalpindi and CMH, Lahore, from July 2008 to July 2011. Methodology: Twenty two biopsy proven cases of T1 and early T2 squamous cell carcinoma of tongue were divided in two equal groups of 11 each labeled as A and B. Tumor was excised by CO/sub 2/ laser in group A while cutting diathermy was done in group B. For both groups tumor excision time, per-operative blood loss, postoperative oral swelling and pain was recorded. Excision time of tumor was assessed in minutes and amount of blood loss in milliliters till complete hemostasis after removal of primary tumor. Postoperatively patients were assessed on 12 hourly basis for 48 hours for pain. Pain was analyzed on visual analogue score 1 - 10. Oral swelling was assessed once after 24 hours and labeled as mild, moderate and severe. Independent sample t-test was applied for analysis of excision time, postoperative pain and per-operative blood loss for both groups. Postoperative swelling was analyzed using Fisher exact test. P-value of < 0.05 was considered significant. Results: The mean age at diagnosis in group A was 49.36 ± 5.27 years, while in group B patients had mean age of 50.73 ± 8.13 years. In group A, 4/11 (36.3%) patients were having tumor stage T1 while 7/11 (63.6%) had T2 stage tumor. In group B, 5/11 (45.4%) were having T1 and 6/11 (54.5%) were having stage T2 tumor. Excision time was significantly shorter for group B (p=0.003), but group A had less postoperative pain (p=0.001), less per-operative blood loss (p=0.001) and less postoperative oral swelling (p=0.021). Conclusion: Early carcinoma tongue is better removed by laser than electrocautery in terms of postoperative morbidity, per-operative blood loss, postoperative pain and oral swelling. (author)

We analyze and apply an alternative to black hole excision based on smoothing the interior of black holes with arbitrary initial data, and solving the vacuum Einstein evolution equations everywhere. By deriving the constraint propagation system for our hyperbolic formulation of the BSSN evolution system we rigorously prove that the constraints propagate causally and so any constraint violations introduced inside the black holes cannot affect the exterior spacetime. We present evolutions of Cook-Pfeiffer binary black hole initial configurations showing that these techniques appear to work robustly for generic data. We also present evidence from spherically symmetric evolutions that for the gauge conditions used the same stationary end-state is approached irrespective of the choice of initial data and smoothing procedure

    Full Text Available CONTEXT (BACKGROUND Pterygium is a frequently occurring progressive ocular surface disorder which is a fleshy triangular wing shaped growth, encroaching from conjunctiva on cornea. Pterygium is frequent in hot, dry, dusty environment and prevalence is 0.3% to 29%. Surgical removal is main treatment for pterygium. The recurrence rate after pterygium surgery varies according to type of surgery. Various surgical modalities tried like simple excision, bare sclera technique, amniotic membrane transplantation and conjunctival autografting. AIM To compare surgical outcome of patient’s own blood Vs 10-0 Nylon for conjunctival autografting in pterygium excision. SETTINGS AND DESIGN It is a prospective randomised interventional control trial, with a sample size of minimum 30 patients in each group studied in a tertiary care hospital from Oct. 2013 to Dec. 2015. METHODS AND MATERIAL Out of 63 patients who underwent pterygium excision, patient’s own blood was used in 32 patients (Group A and 10-0 Nylon suture was used in 31 patients (Group B for conjunctival autografting. All patients were followed up regularly on postoperative day 1, 8, 30, 90 and 180. Variables for postoperative assessment were pain, watering, irritation, redness, graft displacement, graft loss and recurrence. STATISTICAL ANALYSIS Statistical analysis was performed using SPSS 13.0 (SPSS, Chicago. Outcome variables between the two groups were compared using the non-parametric Mann–Whitney U Test. RESULTS The mean surgical time of group B (31.48±6.15 min is significantly high as compared to group A (19.71±5.13 min with p<0.001. The regression analysis revealed that except surgery type, no other variable had significant impact on the duration of surgery. Postoperative symptoms are less in group A as compared to group B. Group B showed two recurrences whereas no recurrence was seen in group A. CONCLUSIONS Conjunctival autografting by patient’s own blood is better than 10-0 Nylon

    We wanted to evaluate the effectiveness of breast magnetic resonance (MR) imaging as a preoperative evaluation modality, as compared with ultrasonography (US) imaging, and we wanted to determine the correlation of MRI and US with using the whole-excised breast histopathology as the standard reference. (Check this and adjust it as needed.) From October 2004 to March 2008, among the 245 patients with breast cancer, 82 patients underwent modified radical mastectomy (MRM). Seven patients were excluded due to receiving neoadjuvant chemotherapy before MRI (n=4) or mammotome excision (n=2) or non-visualization of the mass on US and MR imaging (n=1). The remaining 76 breasts in 75 women (one bilateral) were examined preoperatively with MR imaging and US. On US, 42 cases showed unifocal cancer, 16 showed multifocal cancer and 18 showed multicentric breast cancers. On MRI, 39 cases showed unifocal cancer, 11 showed multifocal cancer and 26 showed multicentric breast cancers. We assessed the US findings to identify the patients who were eligible for breast conservative surgery, and then we evaluated the cancers that were treated with conversion to MRM based on the MR imaging. Histopathologic analysis revealed 45 unifocal, 10 multifocal and 22 multicentric breast cancers. Fifty five of the 76 breasts were indicated for MRM based on the US findings due to multicentric cancers (n=18), unifocal or multifocal lesions near the nipple (n=31), or unifocal or multifocal lesions showing extension towards the nipple (n=6). The remaining 21 breasts were classified as suitable for BCS on US, but 5 patients who desired MRM were excluded. Sixteen breasts were altered to MRM based on the additional findings that were suspicious for malignancy on the MR imaging. Among them, 14 (88%) breasts were adequately converted on the surgical plan to MRM based on the histopathologic verification. The remaining 2 breasts had been overestimated. Breast MRI has a significant effect for the preoperative

    The utility and reliability of assessing molecular biomarkers for translational applications on pre-operative core biopsy specimens assume consistency of molecular profiles with larger surgical specimens. Whether DNA methylation in ductal carcinoma in situ (DCIS), measured in core biopsy and surgical specimens are similar, remains unclear. Here, we compared genome-scale DNA methylation measured in matched core biopsy and surgical specimens from DCIS, including specific DNA methylation biomarkers of subsequent invasive cancer. DNA was extracted from guided 2mm cores of formalin fixed paraffin embedded (FFPE) specimens, bisulfite-modified, and measured on the Illumina HumanMethylation450 BeadChip. DNA methylation profiles of core biopsies exhibited high concordance with matched surgical specimens. Within-subject variability in DNA methylation was significantly lower than between-subject variability (all Pcore biopsy and surgical specimens, 15%, and a pathway analysis of these CpGs indicated enrichment for genes related with wound healing. Our results indicate that DNA methylation measured in core biopsies are representative of the matched surgical specimens and suggest that DCIS biomarkers measured in core biopsies can inform clinical decision-making.

  4.  Surgical excision of extensive anal condylomata is a safe operation without risk of anal stenosis

    Directory of Open Access Journals (Sweden)

    Konrad Wroński


    Full Text Available  Introduction:Anal condylomata acuminata was a well-known disease in ancient times but in recent years there has been a rapidly increasing number of people who suffer from this disease. The main cause of this disease is infection of human papilloma virus (HPV which occurs through sexual contact.Currently there are three different ways to treat anal condylomata. Small changes of anal condylomata can be treated with local therapeutic agents, but the best results of treatment of extensive changes are obtained by surgical techniques.Material/Methods:The study group consisted of 30 patients with diagnosed extensive anal condylomata who underwent surgery in Mikolaj Pirogow High Specialized Hospital in Lodz. The survey was conducted from 2007 to 2011. Patients had been directed to the surgical ward by general surgeons and practitioners, proctologists and urologists. The diagnosis was made after proctological assessment in the knee-chest position.Results:All patients underwent surgery and had complete macroscopic electroexcision of anal condylomata. In the research group there was no mortality. Postoperative complications occurred in 4 (13.3�20patients – postoperative bleeding. Strong pain was present in 14 (46.7�20patients but only in the postoperative period. During postoperative follow-up there was no observed infection in the anal region or recurrence of disease. In the operated group there were no observed cosmetic deformations of the anus and/or the anal canal, narrow anal canal or functional fecal incontinence symptoms.Conclusions:Surgical treatment of anal condylomata is an effective and safe method for the patient. In our research there were no serious postoperative complications or recurrence of the disease during the follow-up period.

  5. Surgical correction of Peyronie's disease via tunica albuginea plication or partial plaque excision with pericardial graft: long-term follow up. (United States)

    Taylor, Frederick L; Levine, Laurence A


    Limited publications exist regarding long-term outcomes of surgical correction for Peyronie's Disease (PD). To report on long-term postoperative parameters including rigidity, curvature, length, sensation, function, and patient satisfaction in men with PD treated surgically via Tunica Albuginea Plication (TAP) or Partial Plaque Excision with Tutoplast Human Pericardial Grafting (PEG). Objective and subjective data regarding patients who underwent either TAP or PEG. We report on 142 patients (61 TAP and 81 PEG) with both objective data and subjective patient reports on their postoperative experience. Patients underwent either TAP or PEG following our previously published algorithm. Data was collected via chart review and an internally generated survey, in which patients were asked about their rigidity, straightness, penile length, sensation, sexual function and satisfaction. Average follow up for TAP patients was 72 months (range 8-147) and 58 months (range 6-185) for PEG patients. At survey time, 93% of TAP and 91% of PEG patients reported curvatures of less than 30o. Rigidity was reportedly as good as or better than preoperative in 81% of TAP and 68% of PEG patients, and was adequate for coitus in 90% of TAP and 79% of PEG patients with or without the use of PDE5i. Objective flaccid stretched penile length measurements obtained pre and postoperatively show an average overall length gain of 0.6 cm (range -3.5-3.5) for TAP and 0.2 cm (range -1.5-2.0) for PEG patients. Sensation was reportedly as good as or better than preoperative in 69% of both TAP and PEG patients; 98% of TAP patients and 90% of PEG are able to achieve orgasm. 82% of TAP patients and 75% of PEG patients were either very satisfied or satisfied. Our long-term results support both TAP and PEG as durable surgical therapy for men with clinically significant PD.

    Purpose: To compare the outcome of patients with invasive breast cancer both with and without lobular carcinoma in situ (LCIS)-positive/close surgical margins after breast-conserving treatment. Methods and Materials: We retrospectively studied 2358 patients with T1-T2 invasive breast cancer treated with lumpectomy and radiation therapy from January 1980 to December 2009. Median age was 57 years (range, 24-91 years). There were 82 patients (3.5%) with positive/close LCIS margins (<0.2 cm) and 2232 patients (95.7%) with negative margins. A total of 1789 patients (76%) had negative lymph nodes. Patients who received neoadjuvant chemotherapy were excluded. A total of 1783 patients (76%) received adjuvant systemic therapy. Multivariable analysis (MVA) was performed using Cox's proportional hazards model. Results: The 5-year cumulative incidence of locoregional recurrence (LRR) was 3.2% (95% confidence interval [CI] 2.5%-4.1%) for the 2232 patients with LCIS-negative surgical margins (median follow-up 104 months) and 2.8% (95% CI 0.7%-10.8%) for the 82 patients with LCIS-positive/close surgical margins (median follow-up 90 months). This was not statistically significant (P=.5). On MVA, LCIS-positive margins after the final surgery were not associated with increased risk of LRR (hazard ratio [HR] 3.4, 95% CI 0.5-24.5, P=.2). Statistically significant prognostic variables on Cox's MVA for risk of LRR included systemic therapy (HR 0.5, 95% CI 0.33-0.75, P=.001), number of positive lymph nodes (HR 1.11, 95% CI 1.05-1.18, P=.001), menopausal status (HR 0.96, 95% CI 0.95-0.98, P=.001), and histopathologic grade (grade 3 vs grade 1/2) (HR 2.6, 95% CI 1.4-4.7, P=.003). Conclusion: Our results suggest that the presence of LCIS at the surgical margin after lumpectomy does not increase the risk of LRR or the final outcome. These findings suggest that re-excision or mastectomy in patients with LCIS-positive/close final surgical margins is unnecessary.

  7. Surgical management of lower urinary mesh perforation after mid-urethral polypropylene mesh sling: mesh excision, urinary tract reconstruction and concomitant pubovaginal sling with autologous rectus fascia. (United States)

    Shah, Ketul; Nikolavsky, Dmitriy; Gilsdorf, Daniel; Flynn, Brian J


    We present our management of lower urinary tract (LUT) mesh perforation after mid-urethral polypropylene mesh sling using a novel combination of surgical techniques including total or near total mesh excision, urinary tract reconstruction, and concomitant pubovaginal sling with autologous rectus fascia in a single operation. We retrospectively reviewed the medical records of 189 patients undergoing transvaginal removal of polypropylene mesh from the lower urinary tract or vagina. The focus of this study is 21 patients with LUT mesh perforation after mid-urethral polypropylene mesh sling. We excluded patients with LUT mesh perforation from prolapse kits (n = 4) or sutures (n = 11), or mesh that was removed because of isolated vaginal wall exposure without concomitant LUT perforation (n = 164). Twenty-one patients underwent surgical removal of mesh through a transvaginal approach or combined transvaginal/abdominal approaches. The location of the perforation was the urethra in 14 and the bladder in 7. The mean follow-up was 22 months. There were no major intraoperative complications. All patients had complete resolution of the mesh complication and the primary symptom. Of the patients with urethral perforation, continence was achieved in 10 out of 14 (71.5 %). Of the patients with bladder perforation, continence was achieved in all 7. Total or near total removal of lower urinary tract (LUT) mesh perforation after mid-urethral polypropylene mesh sling can completely resolve LUT mesh perforation in a single operation. A concomitant pubovaginal sling can be safely performed in efforts to treat existing SUI or avoid future surgery for SUI.

    Full Text Available Background: Breast cancer is a major cause of morbidity and mortality worldwide. Certain lesions encountered on mammography require histological assessment of biopsy samples to identify benign versus malignant disease. Stereotactic vacuum-assisted breast biopsy (SVAB is a useful technique, especially for non-palpable microcalcific lesions, and was introduced at our institution in 2011.Objectives: To determine whether the histological underestimation from 9-gauge SVABs performed at our institution is within acceptable limits.Method: In this cross-sectional study, 9-gauge stereotactic biopsy histology results and breast imaging and reporting data system (BI-RADS findings of 158 lesions (from 153 patients were analysed and the histological findings compared with surgical excision histology results (54 lesions to determine histological underestimation (upgrade rates.Results: One out of eight cases of ductal carcinoma in situ (DCIS was underestimated, yielding a DCIS underestimation rate of 12.5%.Conclusion: The DCIS underestimation obtained from the present study in our institution was on a par with other authors’ findings and was therefore within acceptable limits. Atypical ductal hyperplasia underestimation could not be reliably obtained with the small study population.Keywords: Stereotactic vacuum assisted breast biopsy; histological underestimation; histological upgrade

    Full Text Available Objective: To determine the diagnostic accuracy of ultrasound-guided 14-gauge core-needle breast biopsy (CNB correlation with surgical excision or long term follow-up. Methods: One hundred and fifteen breast lesions which had undergone ultrasound-guided 14-gauge core-needle breast biopsy from May 2003 to Aug 2010 in the Breast Diagnostic Center, King Chulalongkorn Memorial Hospital were included in this study. Clinical history, palpability of the lesion, site of the lesion, the prebiopsy lesion size, ultrasound characteristic, level of suspicion according to the BIRADS classification, number of samples taken and pathologic results of CNB were reviewed and correlated with pathologic results of subsequent open surgery. For benign lesions without surgery, we correlated the result of CNB with stability of the lesion at or more than two-year interval follow-up. The accuracy rate, sensitivity, specificity, false positive rate, false negative rate, positive predictive value and negative predictive value were accessed. The falsenegative diagnoses of core needle biopsy were reviewed in detail. Procedural complications were also observed. Results: Among 115 lesions, 114 lesions were in female and 1 lesion was in male with their mean age of 50.87 years old (ranging from 27-72, 91 lesions were palpable (79.13%, 24 were non-palpable (20.87%. The prebiopsy size was 3.2 cm in diameter ranging from 0.5-20.0 cm. The pathologic results for the CNB were malignancy in 77.39% (89 lesions, high-risk in 0.87% (1 lesion and benign in 21.17% (25 lesions. Five patients were negative for malignancy by core needle biopsy but positive for malignancy by surgical procedure. The sensitivity was 94.68%. The specificity was 100%. The false negative rate was 5.3%. The positive predictive value was 100%. The negative predictive value was 80.76%. The accuracy was 95.65%. There was no false positive case. Conclusions: Core needle biopsy under ultrasound guidance is a minimally

    A case of an arteriovenous malformation (AVM) of the cerebellum and brainstem at the cerebellopontine angle is reported. Though a postoperative angiogram after the first operation indicated complete excision of the lesion, the patient returned with subarachnoid haemorrhage, and an angiogram indicated reappearance of the lesion. Total excision was carried out at the second operation.

    The role of minimally invasive surgery of gastrointestinal stromal tumours (GISTs) of the stomach remains uncertain especially for large and/or difficult located tumours. We are hereby presenting a single-centre series of robot-assisted resections using the da Vinci Surgical System (Si or Xi). Data of patients undergoing robot-assisted treatment of gastric GIST were retrieved from the prospectively collected institutional database and a retrospective analysis was performed. Patients were stratified according to size and location of the tumour. Difficult cases (DCs) were considered for size if tumour was> 50 mm and/or for location if the tumour was Type II, III or IV sec. Privette/Al-Thani classification. Between May 2010 and February 2017, 12 consecutive patients underwent robot-assisted treatment of GIST at our institution. DCs were 10/12 cases (83.3%), of which 6/10 (50%) for location, 2/10 (25%) for size and 2/10 (25%) for both. The da Vinci Si was used in 8 patients, of which 6 (75%) were DC, and the da Vinci Xi in 4, all of which (100%) were DC. In all patients, excision was by wedge resection. All lesions had microscopically negative resection margins. There was no conversion to open surgery, no tumour ruptures or spillage and no intraoperative complications. Our experience suggests a positive role of the robot da Vinci in getting gastric GIST removal with a conservative approach, regardless of size and location site. Comparative studies with a greater number of patients are necessary for a more robust assessment.

    Robotic rectal resection with da Vinci Si has some technical limitations, which could be overcome by the new da Vinci Xi. We compare short-term surgical and functional outcomes following robotic rectal resection with total mesorectal excision for cancer, with the da Vinci Xi (Xi-RobTME group) and the da Vinci Si (Si-RobTME group). The first consecutive 30 Xi-RobTME were compared with a Si-RobTME control group of 30 patients, selected using a one-to-one case-matched methodology from our prospectively collected Institutional database, comprising all cases performed between April 2010 and September 2016 by a single surgeon. Perioperative outcomes were compared. The impact of minimally invasive TME on autonomic function and quality of life was analyzed with specific questionnaires. The docking and overall operative time were shorter in the Xi-RobTME group (p  25 kg/m 2 was necessary in ten patients (45 vs. 0%, p < 0.001) and in six patients (37 vs. 0%, p < 0.05), in the Si-RobTME and Xi-RobTME groups, respectively. There were no differences in conversion rate, mean hospital stay, pathological data, and in functional outcomes between the two groups before and at 1 year after surgery. The technical advantages offered by the da Vinci Xi seem to be mainly associated with a shorter docking and operative time and with superior ability to perform a fully-robotic approach. Clinical and functional outcomes seem not to be improved, with the introduction of the new Xi platform.

  13. Malignant melanoma of the conjunctiva – successful surgical excision of the primary tumor and reconstruction by conjunctival auto transplantation from the contralateral eye. (United States)

    Sivkova, N; Chokoeva, A A; Dobrev, H; Staribratova, D; Belovezhdov, V; Tchernev, G; Wollina, U


    Malignant melanoma of the conjunctiva is a rare tumor with incidence of 0.5 cases/year per million population. It may also occur as de novo, as on the basis of preexisting melanocytic lesions (nevus or freckle) or most often from the so-called primary acquired melanosis of the conjuctiva (PAM). It metastasizes mainly lymphogenic and hematogenous. The size of the primary tumor lesion, histopathological findings and absolute tumor thickness are essential for unfavorable prognosis. Conjunctival auto transplantation from the other eye is modern and innovative, but also a seldomly feasible method of reconstruction after conjunctival excision of tumors in this area. We present a rare case of a 75-year-old patient with epithelioid cell malignant melanoma of the bulbar conjunctiva of the right eye, which de novo occurred, successfully treated by excision of the primary tumor and subsequent reconstruction by conjunctival auto transplant from the other eye. A very good therapeutic and aesthetic result was achieved.

    To develop an approach for radiology-pathology fusion of ex vivo histology of surgically excised pulmonary nodules with pre-operative CT, to radiologically map spatial extent of the invasive adenocarcinomatous component of the nodule. Six subjects (age: 75 ± 11 years) with pre-operative CT and surgically excised ground-glass nodules (size: 22.5 ± 5.1 mm) with a significant invasive adenocarcinomatous component (>5 mm) were included. The pathologist outlined disease extent on digitized histology specimens; two radiologists and a pulmonary critical care physician delineated the entire nodule on CT (in-plane resolution: <0.8 mm, inter-slice distance: 1-5 mm). We introduced a novel reconstruction approach to localize histology slices in 3D relative to each other while using CT scan as spatial constraint. This enabled the spatial mapping of the extent of tumour invasion from histology onto CT. Good overlap of the 3D reconstructed histology and the nodule outlined on CT was observed (65.9 ± 5.2%). Reduction in 3D misalignment of corresponding anatomical landmarks on histology and CT was observed (1.97 ± 0.42 mm). Moreover, the CT attenuation (HU) distributions were different when comparing invasive and in situ regions. This proof-of-concept study suggests that our fusion method can enable the spatial mapping of the invasive adenocarcinomatous component from 2D histology slices onto in vivo CT. (orig.)

  15. A useful alternative approach for the treatment of well-demarcated Basal cell carcinoma: surgical excision and margin control with tzanck smear test. (United States)

    Baba, Mete; Durdu, Murat; Seçkin, Deniz


    To analyze the accuracy of the Tzanck smear test (TST) for margin control in surgery for well-demarcated basal cell carcinoma (BCC). Twenty-one patients with well-demarcated BCC were included in this study. After local anesthesia, the tumors were excised. The pathologist examined the frozen sections. If the tumor cells were observed in the margin, a re-excision was done. This procedure was repeated until the margin was tumor free. After each excision, Tzanck smear samples were taken from the defect area. The samples obtained were stained with May-Grünwald-Giemsa and examined. The accuracy of TST was then analyzed by comparison of the TST results with those of frozen section examination. The sensitivity and specificity of TST for margin assessment were 1.00 (95% confidence interval (CI)=1.00-1.00) and 0.99 (95% CI=0.98-1.00), respectively. Positive and negative predictive values and the diagnostic accuracy for TST were 0.94 (95% CI=0.84-1.05), 1.00 (95% CI=1.00-1.00), and 1.00 (95% CI=0.99-1.00), respectively. No recurrences were observed in the average 2-year follow-up period. The high accuracy of TST for margin control is encouraging to develop a practical alternative approach for the treatment of well-demarcated BCC.

  16. Penile prosthesis implant with bi-triangular excision and graft for surgical therapy of Peyronie’s disease: A case report

    Directory of Open Access Journals (Sweden)

    Alexandre de Freitas Miranda


    Full Text Available We present a case of a 65-year-old man, who presented with moderate erectile dysfunction and a dorsal penile deviation of 60° caused by Peyronie’s disease. The patient underwent bi-triangularshaped plaque excision, followed by grafting and implantation of inflatable penile prosthesis. Complete penile straightening, without mechanical or geometric abnormalities, was achieved using bi-triangular excision and grafting. Postoperatively, the patient reported high satisfaction with the results and could perform sexual intercourse naturally. This novel technique corrects any degree of penile curvature, permits malleable and semi-rigid penile prosthesis implantation, avoids penile length loss, and eliminates additional incisions. To our knowledge, this case is the first in the literature in which the bi-triangular technique was successfully used for penile prosthesis implantation secondary to Peyronie’s disease. This new technique appears to be a good solution to correct penile curvature during penile prosthesis implantation for the treatment of Peyronie’s disease associated with erectile dysfunction.

  17. Giant rhinophyma: Excision with coblation assisted surgery

    Directory of Open Access Journals (Sweden)

    Caner Sahin


    Full Text Available An 83-year-old man presented with an unusually severe case of rhinophyma. Giant rhinopyhma is very rare in literature. The giant lesion was widely excised using sharp surgical incision and coblation assisted surgery. Using direct coblation to the nasal dorsum may cause edema in the surrounding tissue. There was minimal edema in surrounding tissue using this technique. A full thickness-skin graft was applied after excision. Cosmetic and functional postoperative results were satisfactory.

  18. Standard wide local excision or bilateral reduction mammoplasty in large-breasted women with small tumours: Surgical and patient-reported outcomes. (United States)

    Di Micco, R; O'Connell, R L; Barry, P A; Roche, N; MacNeill, F A; Rusby, J E


    Oncoplastic breast surgery is used to extend the role of breast-conserving surgery (BCS) to women with an unfavourable tumour to breast volume ratio. However, large-breasted women with a relatively small breast cancer may be offered bilateral reduction mammoplasty (BRM) despite being suitable for standard BCS as the more complex surgery may have advantages in terms of patient satisfaction and reduced adverse effects of radiotherapy. This retrospective study evaluated surgical and patient-reported outcome measures (PROMs) in large-breasted women with early ( 0.05). Limitations of this study mean it can only be regarded as hypothesis-generating. Nonetheless, the trends merit a prospective study to investigate the optimal management of smaller breast cancers in larger-breasted women.

    International Nuclear Information System (INIS)

    Schmitz-Winnenthal, Friedrich H; Schmidt, Thomas; Lehmann, Monika; Beckhove, Philipp; Kieser, Meinhard; Ho, Anthony D; Dreger, Peter; Büchler, Markus W


    Pancreatic cancer is the third most common cancer related cause of death. Even in the 15% of patients who are eligible for surgical resection the outlook is dismal with less than 10% of patients surviving after 5 years. Allogeneic hematopoietic (allo-HSCT) stem cell transplantation is an established treatment capable of to providing cure in a variety of hematopoietic malignancies. Best results are achieved when the underlying neoplasm has been turned into a stage of minimal disease by chemotherapy. Allo-HSCT in advanced solid tumors including pancreatic cancer have been of limited success, however studies of allo-HSCT in solid tumors in minimal disease situations have never been performed. The aim of this trial is to provide evidence for the clinical value of allo-HSCT in pancreatic cancer put into a minimal disease status by effective surgical resection and standard adjuvant chemotherapy. The STEM PACE trial is a single center, phase II study to evaluate adjuvant allogeneic hematopoietic stem cell transplantation in pancreatic cancer after surgical resection. The study will evaluate as primary endpoint 2 year progression free survival and will generate first time state-of-the-art scientific clinical evidence if allo-HSCT is feasible and if it can provide long term disease control in patients with effectively resected pancreatic cancer. Screened eligible patients after surgical resection and standard adjuvant chemotherapy with HLA matched related stem cell donor can participate. Patients without a matched donor will be used as a historical control. Study patients will undergo standard conditioning for allo-HSCT followed by transplantation of allogeneic unmanipulated peripheral blood stem cells. The follow up of the patients will continue for 2 years. Secondary endpoints will be evaluated on 7 postintervention visits. The principal question addressed in this trial is whether allo-HSCT can change the unfavourable natural course of this disease. The underlying

  20. An arteriovenous fistula following chalazion excision

    Directory of Open Access Journals (Sweden)

    Dias-Amborcar Yuri


    Full Text Available An arteriovenous fistula secondary to a chalazion is a rare occurrence. It may follow spontaneous necrosis or surgical trauma. Digital subtraction angiography and identification of the arterial feeders combined with direct puncture of the nidus and embolization is recommended, as surgical excision becomes much easier and results in a complete excision of the lesion. Conchal cartilage graft is a useful lining material for reconstruction of the tarsal plate due to its natural curvature. It restores lid integrity and ensures a stable and functional eyelid.

  1. Recalcitrant aseptic atrophic non-union of the shaft of the humerus after failure of surgical treatment: management by excision of non-union, bone grafting and stabilization by LCP in different modes. (United States)

    Babhulkar, Sudhir; Babhulkar, Sushrut; Vasudev, Aditya


    Non-union of the humeral shaft is infrequently noticed after surgical fixation. Sixty eight patients whose osteosynthesis of humeral shaft had failed leading to non-union were identified over a duration of 10 years from (January 2006 to December 2015). Clinical and radiographical follow-up was available for 64 patients (4 patients were lost for follow-up), with a mean age of 58 years (range 25-78 years). All patients had aseptic atrophic non-union of either: proximal shaft (n=12), mid shaft (n=38), and lower shaft (n=14). All these patients had failure of primary fixation, with a minimum duration from 36 to 110 weeks. Non-unions were operated by excision of non-union, autogenous bone grafting and osteosynthesis by locking compression plating. Adequate fixation of non-union with bone grafting was achieved in all patients. All non-unions healed well at an average of 16 weeks (range 6-36 weeks). The mean length of follow-up was 120 weeks (range 60-250 weeks). The mean range of movements following healing of non-union was forward flexion of 140°, external rotation and internal rotation of 30° at shoulder and average fixed flexion deformity of 10° and flexion of 130° at elbow. Two patients had postoperative radial nerve palsy because of neuropraxia, which recovered in eight weeks. Three patient developed superficial infections at the iliac crest, which settled with antibiotics, dressings in 3 weeks time and two patients had some discomfort over the fibular graft harvest site. In all patients complete clinical and radiological union was achieved with satisfactory outcome in terms of relief of symptoms and functional improvement in the range of movements. The main points in surgical treatment were complete excision of non-union, correction of deformity, use of plenty of corticocancellous graft, furthermore the use of intramedullary fibula and osteosynthesis by long locking compression plating in different modes of fixation provided good to excellent results and

  2. An Evaluation of the Diagnostic Accuracy of the Grade of Preoperative Biopsy Compared to Surgical Excision in Chondrosarcoma of the Long Bones

    Directory of Open Access Journals (Sweden)

    Robert Jennings


    Full Text Available Chondrosarcoma is the second most common primary malignant bone tumour. Distinguishing between grades is not necessarily straightforward and may alter the disease management. We evaluated the correlation between histological grading of the preoperative image-guided needle biopsy and the resection specimen of 78 consecutive cases of chondrosarcoma of the femur, humerus, and tibia. In 11 instances, there was a discrepancy in histological grade between the biopsy and surgical specimen. Therefore, there was an 85.9% (67/78 accuracy rate for pre-operative histological grading of chondrosarcoma, based on needle biopsy. However, the accuracy of the diagnostic biopsy to distinguish low-grade from high-grade chondrosarcoma was 93.6% (73/78. We conclude that accurate image-guided biopsy is a very useful adjunct in determining histological grade of chondrosarcoma and the subsequent treatment plan. At present, a multidisciplinary approach, comprising experienced orthopaedic surgeons, radiologists, and pathologists, offers the most reliable means of accurately diagnosing and grading of chondrosarcoma of long bones.

  3. Arthroscopic Excision of a Symptomatic Meso-acromiale


    Stetson, William B.; McIntyre, J. Alex; Mazza, Genevieve R.


    The surgical technique for the management of a symptomatic os acromiale remains unclear. Several operative techniques have been described including open excision, open reduction?internal fixation (ORIF), arthroscopic acromioplasty or subacromial decompression, and arthroscopic excision. There are 4 types of os acromiale, with the meso-acromion being the most common and difficult to treat. The excision of a pre-acromion arthroscopically or in an open manner usually produces satisfactory result...

    Vastardis, Iraklis [Ophthalmology Clinic Pallas, Olten (Switzerland); Pajic, Bojan; Pajic-Eggspuehler, Brigitte [Swiss Eye Research Foundation - ORASIS Eye Clinic, Reinach (Switzerland); Greiner, Richard H. [Radiooncology, Cantonal Hospital Luzern (Switzerland); Aebersold, Daniel M. [Dept. of Radiation Oncology, Inselspital, Bern Univ. Hospital (Switzerland)


    Purpose: to evaluate the consecutive treatment results regarding pterygium recurrence and the efficacy of exclusive strontium-/yttrium-90 {beta}-irradiation for primary and recurrent pterygia and to analyze the functional outcome. Patients and Methods: Between October 1974 and December 2005, 58 primary and 21 recurrent pterygia were exclusively treated with strontium-/yttrium-90 {beta}-irradiation with doses ranging from 3,600 to 5,500 cGy. The follow-up time was 46.6 {+-} 26.7 months, with a median of 46.5 months. Results: the treatment led to a size reduction in all pterygia (p < 0.0001). Neither recurrences nor side effects were observed during therapy and follow-up in this study. Best-corrected visual acuity increased (p = 0.0064). Corneal astigmatism was reduced in recurrent pterygia (p = 0.009). Conclusion: exclusive strontium-/yttrium-90 {beta}-irradiation of pterygia is a very efficient and well-tolerated treatment, with remarkable aesthetic and rehabilitative results in comparison to conventional treatments, especially for recurrent lesions which have undergone prior surgical excision.

    Directory of Open Access Journals (Sweden)

    Sangwan S


    Full Text Available Background : Lumbar disc herniation often causes sciatica. Many different techniques have been advocated with the aim of least possible damage to other structures while dealing with prolapsed disc surgically in the properly selected and indicated cases. Methods : Twenty six patients with clinical symptoms and signs of prolapsed lumbar intervertebral disc having radiological correlation by MRI study were subjected to disc excision by interlaminar fenestration method. Results : The assessment at follow-up showed excellent results in 17 patients, good in 6 patients, fair in 2 patients and poor in 1 patient. The mean preoperative and postoperative Visual Analogue Scores were 9.34 ±0.84 and 2.19 ±0.84 on scale of 0-10 respectively. These were statistically significant (p value< 0.001, paired t test. No significant complications were recorded. Conclusion : Procedures of interlaminar fenestration and open disc excision under direct vision offers sufficient adequate exposure for lumbar disc excision with a smaller incision, lesser morbidity, shorter convalescence, early return to work and comparable overall results in the centers where recent laser and endoscopy facilities are not available.

  6. Ulnar nerve entrapment complicating radial head excision

    Directory of Open Access Journals (Sweden)

    Kevin Parfait Bienvenu Bouhelo-Pam

    Full Text Available Introduction: Several mechanisms are involved in ischemia or mechanical compression of ulnar nerve at the elbow. Presentation of case: We hereby present the case of a road accident victim, who received a radial head excision for an isolated fracture of the radial head and complicated by onset of cubital tunnel syndrome. This outcome could be the consequence of an iatrogenic valgus of the elbow due to excision of the radial head. Hitherto the surgical treatment of choice it is gradually been abandoned due to development of radial head implant arthroplasty. However, this management option is still being performed in some rural centers with low resources. Discussion: The radial head plays an important role in the stability of the elbow and his iatrogenic deformity can be complicated by cubital tunnel syndrome. Conclusion: An ulnar nerve release was performed with favorable outcome. Keywords: Cubital tunnel syndrome, Peripheral nerve palsy, Radial head excision, Elbow valgus

  7. Value of histopathologic analysis of subcutis excisions by general practitioners

    Directory of Open Access Journals (Sweden)

    Verweij Wim


    Full Text Available Abstract Background Only around 60% of skin lesions excised by GPs are referred to a pathologist. Clinical diagnoses of skin excisions by GPs may not be very accurate. Subcutis excisions are rarely done by GPs, and there is hence little information in the literature on the histopathological yield of subcutis excisions by GPs with regard to malignancies. The aim of this study was to evaluate the yield of histopathological investigation of a relatively large group of subcutis excisions by GPs, with special emphasis on discrepancies between clinical and histopathological diagnoses of malignancy. Methods We investigated a series of 90 subcutis excisions, which was derived from a database of consecutive GP submissions from the years 1999–2000 where in the same time period 4595 skin excisions were performed by the same group of GPs. This underlines the apparent reluctance of GPs to perform subcutis excisions. Results The final diagnosis was benign in 88 cases (97.8% and malignant in 2 cases (2.2%. Seven cases had no clinical diagnosis, all of which were benign. Of the 83 clinically benign cases, 81 (97.6% were indeed benign and 2 (2.4% were malignant: one Merkel cell carcinoma and one dermatofibrosarcoma protuberans. The former was clinically thought to be a lipoma, and the latter a trichilemmal cyst. The dermatofibrosarcoma protuberans presented at the age of 27, and the Merkel cell carcinoma at the age of 60. Both were incompletely removed and required re-excision by a surgical oncologist. Conclusion Histopathological investigation of subcutis excisions by GPs yields unexpected and rare malignancies in about 2% of cases that may initially be excised inadequately. Based on these data, and because of the relatively rareness of these type of excisions, it could be argued that it may be worthwhile to have all subcutis excisions by GPs routinely investigated by histopathology.

  8. The Versajet water dissector: a new tool for tangential excision. (United States)

    Klein, Matthew B; Hunter, Sue; Heimbach, David M; Engrav, Loren H; Honari, Shari; Gallery, Ellen; Kiriluk, Diane-Marie; Gibran, Nicole S


    Goulian and Watson knives work well for tangential burn excision on large flat areas. They do not work well in small areas and in areas with a three-dimensional structure. The Versajet Hydrosurgery System (Smith and Nephew, Key Largo, FL) is a new waterjet-powered surgical tool designed for wound excision. The small size of the cutting nozzle and the ability to easily maneuver the water dissector into small spaces makes it a potentially useful tool for excision of burns of the eyelids, digits and web spaces. The Versajet Hydrosurgery System contains a power console that propels saline through a handheld cutting device. This stream of pressurized saline functions as a knife. We have used the Versajet for burn excision in 44 patients. Although there is a learning curve for both surgeons using and operating room staff setting up the device, the Versajet provides a relatively facile method for excision of challenging aesthetic and functional areas.

  9. Excise Taxes with Multiproduct Transactions


    Stephen F. Hamilton


    I examine excise taxes levied on multiproduct retailers. Excise taxes reduce equilibrium output and decrease equilibrium product variety in the short run, but taxes can raise output per product in the long run and induce entry. Excise taxes are overshifted into prices in a wide range of cases, including under linear and concave demand conditions, and excise taxes shift less than one-for-one into prices only when demand is highly convex. Multiproduct transactions substantively alter the effici...

    New Nuclear Medicine techniques to help the surgeon in the operation room are now being introduced. They aim to get a better location of the objective or a shorter duration of the surgical process. The selective radio guided biopsy of the sentinel node included in the clinical practise guidelines for the surgery of tumours as breast cancer and malignant melanoma is the paradigm of this new techniques. Other techniques are intraoperatory detection with probes or portable gamma cameras of tumour lesions as parathyroid adenomas, metastatic neuroendocrine tumours and other tumours. (Author) 16 refs.

  11. Robotic Extramucosal Excision of Bladder Wall Leiomyoma

    Directory of Open Access Journals (Sweden)

    Khalid E. Al-Othman


    Full Text Available Introduction: Multiple case reports and reviews have been described in the literature for bladder wall leiomyoma resection via different approaches. The minimally invasive partial cystectomy remains the most widely accepted technique; however, case reports for enucleation of bladder wall leiomyoma have also been described. The purpose of this video is to demonstrate the robotic extramucosal excision of a bladder wall leiomyoma, without cystotomy, but with complete removal of the muscular layer. Materials and Methods: A 35-year old male present with lower urinary tract symptoms and imaging showed bladder wall mass with histopathology showed leiomyoma. The patient consented for mass excision with the possibility of a partial cystectomy. The patient was placed in the supine, 30-degree Trendelenburg position during the procedure. A total of 4 ports were inserted. A 3-arm da Vinci robotic surgical system was docked, and the arms were connected. Extramucosal excision was accomplished without cystotomy and muscle approximation was achieved by 2 0 Vicryle. Result: The operative time was 90 minutes, blood loss of approximately 50mL and the patient was discharged after 72 hours with no immediate complications and a 6 months follow-up showed no recurrence. Conclusion: Such a technique results in complete excision of the tumor, without cystotomy, and also maintains an intact mucosa. These steps, in addition to decreasing the risk of local recurrence, also shorten the period of postoperative catheterization and hospitalization.

  12. Nasal base narrowing: the combined alar base excision technique. (United States)

    Foda, Hossam M T


    To evaluate the role of the combined alar base excision technique in narrowing the nasal base and correcting excessive alar flare. The study included 60 cases presenting with a wide nasal base and excessive alar flaring. The surgical procedure combined an external alar wedge resection with an internal vestibular floor excision. All cases were followed up for a mean of 32 (range, 12-144) months. Nasal tip modification and correction of any preexisting caudal septal deformities were always completed before the nasal base narrowing. The mean width of the external alar wedge excised was 7.2 (range, 4-11) mm, whereas the mean width of the sill excision was 3.1 (range, 2-7) mm. Completing the internal excision first resulted in a more conservative external resection, thus avoiding any blunting of the alar-facial crease. No cases of postoperative bleeding, infection, or keloid formation were encountered, and the external alar wedge excision healed with an inconspicuous scar that was well hidden in the depth of the alar-facial crease. Finally, the risk of notching of the alar rim, which can occur at the junction of the external and internal excisions, was significantly reduced by adopting a 2-layered closure of the vestibular floor (P = .01). The combined alar base excision resulted in effective narrowing of the nasal base with elimination of excessive alar flare. Commonly feared complications, such as blunting of the alar-facial crease or notching of the alar rim, were avoided by using simple modifications in the technique of excision and closure.

  13. Sacrococcygeal teratoma excision: a vertical rather than transverse ...

    African Journals Online (AJOL)

    Overall, we did not find the vertical approach to add any extra limitations to the surgical exposure or dissection; meanwhile, it provided a well-recognized cosmetic advantage. Conclusion: The vertical posterior sagittal approach for excision of SCT is both feasible and advantageous in terms of the cosmetic outcome.

    Lutz, Charles J; Bhamidipati, Castigliano M; Ford, Brant; Swartz, Mike; Hauser, Michael; Kyobe, Moses; Dilip, Karikehalli


    : Left ventricular thrombus is a rare entity usually associated with myocardial infarction. The daVinci Surgical System (Intuitive Surgical, Inc., Sunnyvale, Calif) offers excellent visualization of the mitral subvalvular apparatus and should provide an effective means to excise a left ventricular mass. : A 34-year-old man presented to an outside institution with fever of unknown origin and ulcerative colitis. As part of this workup, he underwent a transthoracic echocardiogram and subsequently a transesophageal echocardiogram that showed a 2-cm left ventricular apical pedunculated mass. He was referred to our institution for excision of this ventricular mass. Because of the pedunculated nature of the mass, he was deemed a candidate for a robotic-assisted minimally invasive approach. : The patient underwent successful robotic-assisted excision of a left ventricular mass. Total robotic time was 15 minutes. Pathology revealed that the mass was a left ventricular thrombus. The patient experienced an uneventful recovery and was discharged home in 4 days. : Left ventricular mass excision can be safely performed with the daVinci Surgical System. The daVinci Surgical System offers excellent visualization of the entire left ventricular cavity.

  16. Trans-sphenoidal excision of craniopharyngiomas.

    Directory of Open Access Journals (Sweden)

    Nagpal R


    Full Text Available Craniopharyngiomas have been by and large excised by the transcranial route. Since 1982, 11 patients have been operated by the traus-sphensidal route in the department. The clinical features with which they were presented, diagnostic investigations, details of surgical procedures and follow-up analysis is being presented here. A retrospective study of radiological investigation was done to determine the features that help decide the choice of surgical approach to these lesions. Only lesions that were primarily intrasellar, cystic and those that expanded the sella could be treated by the trans-sphenoidal route. Associated suprasellar extensions could also be removed. Predominantly calcified or firm, fleshy tumours lent themselves poorly to removal by the trans-sphenoidal route.

    Cha, Yoon Ki; Kim, Ji Young; Jeong, Myeong Ja; Kim, Jae Hyung; Kim, Soung Hee; Kim, Soo Hyun; Jun, Woo Sun; Park, Kyeong Mee; Yang, Keun Ho


    Myofibroblastoma of the breast is a rare benign mesenchymal tumor that is known to occur in middle-aged and elderly men, yet there are some recent reports showing no certain difference for the gender distribution of this malady. Localized mass excision can usually provide a complete cure. To the best of our knowledge, there have been no reports of metastasis or recurrence of this tumor. Here we describe the sonographic findings of a case of recurrent myofibroblastoma after surgical excision for suspected fibroadenomas in both breasts of a 25-year-old woman

  20. "How I do it"--plastic surgery: practical suggestions on facial plastic surgery. Surgical excision and primary reconstruction of a moderate size tumor involving the nasal tip and dorsum. (United States)

    Henley-Cohn, J


    A moderate size tumor of the nasal tip and dorsum is excised and the large defect is primarily reconstructed with local flaps without obliteration of natural convexities and concavities. This is achieved by judicious utilization of numerous techniques. The techniques utilized are a V to Y advancement that produce a partial mobilization of the nasal dorsal skin, a full reduction rhinoplasty that dropped the nasal bony roof allowing for further mobilization of the nasal dorsal skin and allowed for tip elevation. A third technique that was utilized was a Z plasty as applied to correction of raised webs. The excess dorsal skin was converted into the needed length to close the tip defect. The patient tolerated this procedure well. His postoperative course was without complications. Postoperative results were good, but there was some persistent tip elevation that perhaps gave him a too youthful appearance for his age (Fig. 2). A novel use of V to Y advancement, Z plasty, and reduction rhinoplasty is described when used concurrently to primarily close a defect of the nasal tip and dorsum.

    Full Text Available OBJECTIVE: to analyze the value of fine needle aspiration and the rates of postoperative complications in patients undergoing resection of the submandibular gland. METHODS: we analyzed the records of patients treated with resection of the gland from January 1995 to December 2008. The data collected included age, gender, findings on clinical history, surgical procedure, results of fine needle aspiration (FNA, pathological diagnosis and complications. RESULTS: 117 patients were studied, aged 12-89 years (mean 48, 70 women and 47 men. Thirty-nine patients (33.3% were affected by inflammatory diseases (28 patients with lithiasis, 70 had benign tumors, and malignant tumors, eight. Regarding FNA, the sensitivity and specificity were 85.7% and 100%, respectively. Nine patients (7.7% had temporary paralysis of the marginal mandibular nerve and one had permanent paralysis. CONCLUSION: resection of the submandibular gland is a safe procedure, with low complication rates.

  2. Laparoscopic Radiofrequency Ablation Combined with Surgical Excision for Exophytic Renal Angiomyolipoma: A Novel Technique Based on Tumor Vasculature Features of Enhancing Renal Masses Toward Hilar Off-Clamping Nephron-Sparing Surgery. (United States)

    Xiong, Wei; Ran, Qing; Du, Yangchun; Lv, Ji; Chen, Fang; Zhong, Shan; Guo, Pu; Dou, Ke; Sun, Minghan


    Symptomatic angiomyolipoma (AML) and asymptomatic AML larger than 4 cm in size are usually treated with nephron-sparing surgery or transarterial embolization. We used radiofrequency ablation to treat the vascular pedicle of exophytic AML with low R.E.N.A.L. nephrometry score and investigated its feasibility for hilar off-clamping nephron-sparing surgery. Contrast-enhanced computed tomography (CT) showed enhanced, well-defined lipomatous tumors with a maximum diameter of 4-8 cm in the kidney of 15 patients. Results indicated that the exophytic tumors featured in the enlarged tumor vasculatures extended into the parenchyma of the involved kidney. The patients underwent radiofrequency ablation by using a Cool-tip™ probe placed into the root of the AML mass from different directions under laparoscopic ultrasonography guidance. After sealing the vascular pedicle of the tumor, the bloodless tumors were resected en bloc without renal hilar clamping or suturing the resection defect of the kidney. All patients underwent the procedure smoothly, and no perioperative complications occurred. The contrast-enhanced CT scan showed small defects in the contrast-enhanced renal parenchyma at third month after the procedure, and the decrease in function of the treated kidneys was radiofrequency ablation based on the tumor vasculature features of a renal mass is an alternative to hilar clamping in laparoscopic nephron-sparing surgery. Laparoscopic radiofrequency ablation and tumor excision are a definitive and safe minimally invasive procedure that allows the successful removal of exophytic sporadic AML mass with low R.E.N.A.L. nephrometry score.

    Hamid, Raashid; Hafeez, Aadil; Darzi, Ashraf M; Zaroo, Inam; Owais, Habib; Akhter, Afrozah


    The main objective of the present study was to study the outcome of surgical treatment of dermatofibrosarcoma protuberans. This study included 45 patients both retrospective and prospective from December 1995 to December 2010. Out of 45 patients, 30 were males and 15 females with the male to female ratio of 2:1. Mean age of presentation was 38.4 + 13.2 years. Commonest mode of presentation was raised firm multinodular lesion with fixity to overlying skin. Site distribution was 42.22% trunk, 57.88% extremities and head and neck. None of the patients had lymph node involvement All patients underwent wide local excision. On histological examination, 8 patients had positive margins. Overall recurrence rate was 22.22%. (please clarify what is the difference between the rate of recurrence following surgery and the overall recurrence rate) Only 2 patients developed metastasis to lungs in the course of their follow-up. Out of 45 patients, 35 remained recurrence free over a varying period of 5 months to 13 years (mean 68 months). Ten patients developed one or more local recurrences. Average time from initial treatment to recurrence was 32 months. All patients with recurrent tumors were subjected to salvage treatment, i.e., re-excision. Average recurrence-free period was 36 + 44 months within a mean follow-up of 68 months. Because of the potential of local recurrence, therapy for DFSP should be directed toward adequate local excision of the primary lesion. Minimal resection should include a surrounding margin, comprising 3-cm margin of normal skin and removal of underlying deep fascia. Compromising on margins invites higher chances of local recurrence.

  4. Lingual Thyroid Excision with Transoral Robotic Surgery

    Full Text Available Ectopic thyroid gland may be detected at any place between foramen caecaum and normal thyroid localization due to inadequacy of the embryological migration of the thyroid gland. It has a prevalence varying between 1/10.000 and 1/100000 in the community. Usually follow-up without treatment is preferred except for obstructive symptoms, bleeding, and suspicion of malignity. Main symptoms are dysphagia, dysphonia, bleeding, dyspnea, and obstructive sleep apnea. In symptomatic cases, the first described method in surgical treatment is open approach since it is a region difficult to have access to. However, this approach has an increased risk of morbidity and postoperative complications. Transoral robotic surgery, which is a minimally invasive surgical procedure, has advantages such as larger three-dimensional point of view and ease of manipulation due to robotic instruments. In this report, a case at the age of 49 who presented to our clinic with obstructive symptoms increasing within the last year and was found to have lingual thyroid and underwent excision of ectopic thyroid tissue by da Vinci surgical system is presented.

  5. [Treatment of Buruli ulcer desease by excision and skin graft]. (United States)

    Ouattara, D; Meningaud, J P; Kaba, L; Sica, A; Asse, H


    Buruli ulcer is the most common mycobacteria disease after leprosy and tuberculosis. The purpose of our study is to make our contribution to the surgical treatment of Buruli ulcer and to asses our results. One hundred eighteen patients presenting progressive Buruli ulcers were operated on. The surgical procedure included excisions for necrotic lesions and grafts for clean wounds. The results were estimated on the time of hospitalization and appearance of complications. Seventy-three patients (62%) were subjected to excision followed by thin skin grafts and 35 patients (30%) were subjected to grafts only. The number of excision times varies from 1 to 7 per patient and from 1 to 4 for the skin grafts. All our patients heal within a period of 120 days with extremes going from 14 to 265 days. We deplored 26 complications (22%): eight new focus, seven infectious complications, six recurrences, five stiffnesses and ankyloses. The treatment of Buruli ulcer by excision and grafts is efficient but does not prevent recurrences and new focus from happening and for their prevention, it is necessary to discover pharmaceutical molecules that are efficient on Mycobacterium ulcerans.

    Malik, Vinod


    BACKGROUND: Basal cell carcinomas are the most prevalent of all skin cancers worldwide and form the majority of the surgical workload for most modern cutaneous malignancy centres. Primary surgical removal of basal cell carcinomas remains the gold standard of treatment but, despite almost two centuries of surgical experience, rates of incomplete surgical excision of up to 50% are still reported. The aim of this study was to assess, quantify and perform comparative analysis of the outcomes and predictive factors of consecutive primarily-excised basal cell carcinomas in a tertiary centre over a six-year period. METHODS: Retrospective audit was conducted on all patients who underwent surgical excision of basal cell carcinomas from January 2000 to December 2005. Assessment parameters included patient biographics, tumour management differences and detailed histopathological analysis of tumour margins and subtypes. RESULTS: One thousand eight hundred and thirty two basal cell carcinomas were excised from 1329 patients over the designated time period. Two hundred and fifty one (14%) lesions were incompletely excised with 135 (7.4%) involving the peripheral margin only, 48 (2.6%) the deep margin only and 41 (2.2%) involving both. Nasal location was the most common predictor of incomplete excision. CONCLUSIONS: Overall basal cell carcinomas excision rates compared favourably with international reported standards but attention to a variety of surgical and histological risk factors may improve this further.

    Zemba, M; Stamate, Alina-Cristina; Avram, Corina Ioana; Sîrbu, Laura Nicoleta Urucu; Camburu, Raluca Lăcrămioara; Ochinciuc, Uliana; Burcea, M


    Surgical treatment for conjunctival neoplasms, with wide local excision, with or without supplemental cryotherapy to the surgical margins represents the treatment of choice for this pathology. In some cases, these neoplasms can be diffuse or multifocal, with borders that are difficult to detect clinically, such that topical therapies offer a more efficient method for treating the entire ocular surface, delivering high drug concentrations at this level, with negligible systemic side effects. Beginning from the clinical case of a patient diagnosed with conjunctival intraepithelial neoplasia, we try to present other therapeutical alternatives, although in this case the therapeutical approach was the classic one.

  9. The effects of chalazion excision on corneal surface aberrations. (United States)

    Park, Young Min; Lee, Jong Soo


    This study is the first to consider the effects of chalazion on corneal surface aberrations taking into account of corneal zones, and to establish the size standard for the excision of chalazion. Twenty three eyes from 23 patients with central upper eyelid chalazion larger than 3mm were recruited in this prospective study. The participants were classified into two groups, depending on size of the lesion: Group 1 with lesion size 3-5mm and Group 2 with lesion size >5mm Chalazion was excised by standard transconjunctival vertical incision. Corneal surface aberrations were measured using a Galilei™ analyzer and an auto-refractometer before and 2 months after the excision. Corneal astigmatism in all patients decreased significantly in both auto refractometer (P=0.012) and Galilei™ (P=0.020) measurements after chalazion excision. RMS of total HOAs decreased significantly in 6mm (P=0.043) and 3mm zone (P=0.051). The RMS of Zernike orders in the vertical and horizontal trefoil decreased significantly in 6mm (P=0.035) and 3mm (P=0.041) zone. Group 2 showed a significant decrease in corneal astigmatism in both auto refractometer (P=0.040) and Galilei™ (P=0.017) parameters after chalazion excision. Group 1 showed an insignificant decrease in corneal astigmatism. Unlike Group 1, the RMS of total HOAs and vertical and horizontal trefoil in 6mm zone decreased significantly in Group 2 (Pchalazion increases astigmatism and HOAs, especially at the peripheral cornea. Significantly induced astigmatism and HOAs are caused by chalazion >5mm in size. Thus, we recommend the surgical excision of chalazion >5mm in size to reduce corneal surface aberrations.

  10. Nasal encephalocele: endoscopic excision with anesthetic consideration. (United States)

    Abdel-Aziz, Mosaad; El-Bosraty, Hussam; Qotb, Mohamed; El-Hamamsy, Mostafa; El-Sonbaty, Mohamed; Abdel-Badie, Hazem; Zynabdeen, Mustapha


    Nasal encephalocele may presents as a nasal mass, its treatment is surgical and it should be done early in life. When removal is indicated, there are multiple surgical approaches; including lateral rhinotomy, a transnasal approach and a coronal flap approach. However, the treatment of a basal intranasal encephalocele using transnasal endoscopic approach could obviates the possible morbidity associated with other approaches. The aim of this study was to evaluate the efficacy of endoscopic removal of intranasal encephalocele, also to document the role of anesthetist in the operative and postoperative periods. Nine cases with nasal encephalocele were included in this study; CT and/or MRI were used in their examination. The lesions were removed via transnasal endoscopic approach. Preoperative evaluation, intervention and postoperative follow-up were presented with discussion of anesthesia used for those children. The lesions of all patients were removed successfully with no recurrence through the follow-up period of at least 21 months. No cases showed morbidity or mortality intra- or post-operatively. Endoscopic excision of intranasal encephalocele is an effective method with high success rate. Anesthetist plays an important role in the operative and postoperative period, even during the endoscopic follow up; sedation of the children is usually needed.

    Full Text Available An 81-year-old woman was admitted with a nodular cutaneous melanoma of the abdominal wall involving the umbilicus. After performing wide excision with 2 cm margin of the melanoma, umbilical reconstruction and defect closure were planned. After careful consideration, we decided to use an island pedicle flap which allowed closure of the defect and reconstruction of the umbilicus.

  13. Deficiency of UV-induced excision repair in human thymocytes

    International Nuclear Information System (INIS)

    Gensler, H.L.; Lindberg, R.E.; Pinnas, J.L.; Jones, J.F.


    The capacity of human thymocytes and of differentiated lymphocytes circulating in peripheral blood to perform unscheduled DNA synthesis (a measure of nucleotide excision repair) after UV irradiation was measured by radioautographic analysis. Only 4% of immature T lymphocytes, but 68% of circulating lymphocytes exhibited unscheduled DNA synthesis. When UV sensitivity of peripheral blood lymphocytes and thymocytes from the same donor were compared, the thymocytes, in each case, were significantly more UV sensitive than were the circulating lymphocytes. Peripheral blood lymphocytes from subjects undergoing halothane and morphine anesthesia during surgery showed 56% less excision repair capacity than those from unanesthetized donors. The difference occurred in the number of cells capable of repair rather than in the extent of repair synthesis per cell. Ultraviolet-induced unscheduled DNA synthesis occurred in only 3% of the thymocytes removed from rats killed by cervical dislocation. Therefore, the deficiency of excision repair was observed in rat thymocytes which had not been affected by anesthesia or surgical trauma. The results indicate that immature T-cells are deficient in nucleotide excision repair whereas the majority of mature peripheral blood lymphocytes exhibit such repair. (author)

    DEFF Research Database (Denmark)

    Maynard, Scott; de Souza-Pinto, Nadja C; Scheibye-Knudsen, Morten


    The main source of mitochondrial DNA (mtDNA) damage is reactive oxygen species (ROS) generated during normal cellular metabolism. The main mtDNA lesions generated by ROS are base modifications, such as the ubiquitous 8-oxoguanine (8-oxoG) lesion; however, base loss and strand breaks may also occur....... Many human diseases are associated with mtDNA mutations and thus maintaining mtDNA integrity is critical. All of these lesions are repaired primarily by the base excision repair (BER) pathway. It is now known that mammalian mitochondria have BER, which, similarly to nuclear BER, is catalyzed by DNA...

  16. Surgical Treatment of Skin Tumors

    Directory of Open Access Journals (Sweden)



    Full Text Available When we mention about surgical treatment of any tumor residing on the skin independent of its benign or malignant nature, the first method we recall is excision. Elliptical excision is the mainstay of the dermatologic surgery. Each excision ends with a defect for which we are responsible to repair functionally and cosmetically. The diameter of the tumor we excised and the safety margin used for excision determine the diameter of the final defect. After achieving tumor free lateral and deep margins with the appropriate surgical method, we decide between the repair options of second intention healing, primary repair, flaps, full or split thickness grafts, considering the diameter and the anatomic localization of the defect, for the best functional and cosmetic result for that specific defect. This review overviews not only the most common dermatologic surgical methods, but also Mohs surgery which is a method rarely used in our country, although it is the treatment of choice for the treatment of high risk basal cell carcinoma (BCC and squamous cell carcinoma (SCC.

  17. The Surgical Treatment of Mycetoma.

    Directory of Open Access Journals (Sweden)

    Suleiman Hussein Suleiman


    Full Text Available Surgical intervention is an integral component in the diagnosis and management of mycetoma. Surgical treatment is indicated for small, localised lesions and massive lesions to reduce the mycetoma load and to enable better response to medical therapy. It is also a life-saving procedure in patients with massive disease and sepsis. Surgical options for mycetoma treatment range from a wide local surgical excision to repetitive debridement excisions to amputation of the affected part. Adequate anaesthesia, a bloodless field, wide local excision with adequate safety margins in a suitable surgical facility, and expert surgeons are mandatory to achieve the best surgical outcome. Surgical intervention in mycetoma is associated with considerable morbidity, deformities, and disabilities, particularly in advanced disease. These complications can be reduced by educating patients to seek medical advice earlier when the lesion is small, localised, and amenable to surgery. There is no evidence for mycetoma hospital cross infection. This communication is based on the authors' experience in managing over 7,200 mycetoma patients treated at the Mycetoma Research Centre, University of Khartoum, Sudan.

    Holt, D; Prymak, C; Evans, S


    Two dogs with tumors in the left nasal vestibule were treated by surgical excision of the affected part of the nose. Radiation and chemopotentiation were used in one dog, which remained tumor-free after 12 months. When recovering from anesthesia, the second dog developed respiratory distress associated with upper airway obstruction and failure to mouth breathe. The dog was successfully treated by temporary tracheostomy and remained tumor-free after 3 months. Surgery preserved the function of the right nostril and gave an acceptable cosmetic result in both cases.

    The present study reports the clinical results of excision of a symptomatic os trigonum using an endoscopic procedure in professional ballet dancers. The hypothesis was that posterior endoscopic excision of the os trigonum would be safe and effective in treating posterior ankle impingement syndrome related to the os trigonum. Twelve professional dancers underwent excision of a symptomatic os trigonum for PAIS using a posterior endoscopic technique after failure of conservative treatment. The patients were evaluated pre- and postoperatively according to the American Orthopaedic Foot and Ankle Society hindfoot scale score, the Tegner activity scale score, and the visual analog scale score. The surgical time, timing of a return to sports, patient satisfaction, and any complications related to the procedure were recorded. The average postoperative follow-up duration was 38.9 ± 20.6 (range 12 to 72) months. The mean Tegner activity scale score increased from 4.3 ± 0.8 (range 3 to 5) preoperatively to 9 ± 0.2 postoperatively (p os trigonum using a 2-portal technique after failure of conservative treatment is characterized by excellent results with low morbidity.

  4. Base excision repair in sugarcane

    Directory of Open Access Journals (Sweden)

    Agnez-Lima Lucymara F.


    Full Text Available DNA damage can be induced by a large number of physical and chemical agents from the environment as well as compounds produced by cellular metabolism. This type of damage can interfere with cellular processes such as replication and transcription, resulting in cell death and/or mutations. The low frequency of mutagenesis in cells is due to the presence of enzymatic pathways which repair damaged DNA. Several DNA repair genes (mainly from bacteria, yeasts and mammals have been cloned and their products characterized. The high conservation, especially in eukaryotes, of the majority of genes related to DNA repair argues for their importance in the maintenance of life on earth. In plants, our understanding of DNA repair pathways is still very poor, the first plant repair genes having only been cloned in 1997 and the mechanisms of their products have not yet been characterized. The objective of our data mining work was to identify genes related to the base excision repair (BER pathway, which are present in the database of the Sugarcane Expressed Sequence Tag (SUCEST Project. This search was performed by tblastn program. We identified sugarcane clusters homologous to the majority of BER proteins used in the analysis and a high degree of conservation was observed. The best results were obtained with BER proteins from Arabidopsis thaliana. For some sugarcane BER genes, the presence of more than one form of mRNA is possible, as shown by the occurrence of more than one homologous EST cluster.

    Harling, Leanne; Athanasiou, Thanos; Ashrafian, Hutan; Kokotsakis, John; Brown, Virginia; Nathan, Anthony; Casula, Roberto


    Papillary fibroelastomas are rare primary tumours of cardiac origin accounting for approximately 10% of all primary cardiac neoplasms. Due to a high thromboembolic risk, surgical excision is the mainstay of treatment in these patients and median sternotomy the most widely used approach. We describe the case of a 43 year-old lady presenting with acute myocardial infarction secondary to aortic valve papillary fibroelastoma subsequently excised using a minimal access technique. From our experience mini-sternotomy offers excellent exposure and allows for safe resection in such cases, improving cosmesis without compromising either intra or post-operative outcome.

  11. Effects of chalazion excision on ocular aberrations. (United States)

    Sabermoghaddam, Ali A; Zarei-Ghanavati, Siamak; Abrishami, Mojtaba


    The goal of this study was to compare higher-order aberrations before and after upper lid chalazion excision. Fourteen eyes from 12 patients (8 females, mean age: 28.7 ± 2.7 years) with upper lid chalazion were enrolled in this prospective interventional case series. Chalazia were excised by standard transconjunctival vertical incision. Ocular aberrations were evaluated by aberrometry (ZyWave) before and 2 months after chalazion excision. Root mean square of total higher-order aberrations decreased from 0.67 ± 0.12 to 0.43 ± 0.15 μm (P = 0.012) after excision. The root mean square of Zernike orders in the vertical and horizontal trefoil and horizontal coma were decreased after excision. Orbscan IIz tomography showed a statistically significant decrease in 5 mm zone irregularity (P = 0.027) and an increase in minimum simulated keratometry after surgery (P = 0.046). Chalazion increases higher-order aberrations, as measured by the Hartmann-Shack aberrometer, which could affect the preoperative evaluation and results of refractive surgery, especially wavefront-guided approaches. Chalazion excision could reduce ocular aberrations and is recommended before refractive surgeries.

  12. Conservative treatment of rectal cancer with local excision and postoperative radiation therapy

    International Nuclear Information System (INIS)

    Minsky, B.D.


    The conventional surgical treatment for patients with potentially curable transmural and/or node positive rectal cancer is a low anterior resection or abdominoperineal resection. Recently, there has been increasing interest in the use of local excision and postoperative radiation therapy as primary therapy for selected rectal cancers. The limited data suggest that the approach of local excision and postoperative radiation therapy should be limited to patients with either T 1 tumours with adverse pathological factors or T 2 tumours. Transmural tumours, which have a 24% local failure rate, are treated more effectively with standard surgery and pre- or postoperative therapy. The results of local excision and postoperative radiation therapy are encouraging, but more experience is needed to determine if this approach ultimately has similar local control and survival rates as standard surgery.

  13. Frontal recurrence of medulloblastoma five years after excision and craniospinal irradiation

    Directory of Open Access Journals (Sweden)

    Roka Y


    Full Text Available Medulloblastomas were originally classified under gliomas of the cerebellum until Bailey and Cushing in 1925 named these tumors as medulloblastoma. At present these tumors are classified under primitive neuroectodermal tumor. Surgical excision followed by craniospinal irradiation is the treatment of choice. A 13-year-old-girl operated for posterior fossa medulloblastoma 5 years ago presented with history of headache and vomiting on and off for 4 days in late August 2008. The MRI showed left frontal tumor which on excision was reported as medulloblastoma. Even after optimal treatment reports of recurrence abound in literature. The most common location is in the posterior fossa, followed by spinal, supratentorial, and uncommonly, systemic metastases. We conclude that medulloblastomas are highly aggressive tumor with high local recurrences if the initial excision is incomplete and that recurrence in the supratentorial area although uncommon is still a possibility. This mandates regular follow up of these children till adulthood to catch early recurrences and metastatic disease.

    Full Text Available Abstract Background Bony ankylosis of elbow is challenging and difficult problem to treat. The options are excision arthroplasty and total elbow replacement. We report our midterm results on nine patients, who underwent inverted 'V' osteotomy excision arthroplasty in our hospital with good functional results. Materials Our case series includes 9 patients (seven males and two females with the mean age of 34 years (13-56 years. Five patients had trauma, two had pyogenic arthritis, one had tuberculous arthritis, and one had pyogenic arthritis following surgical fixation. Results The average duration of follow up is 65 months (45 months-80 months. The mean Mayo's elbow performance score (MEPS preoperatively was 48 (35-70. The MEPS at final follow up was 80 (60-95. With no movement at elbow and fixed in various degrees of either flexion or extension preoperatively, the mean preoperative position of elbow was 64°(30°to 100°. The mean post operative range of motion at final follow up was 27°of extension (20-500, 116°of flexion (1100-1300, and the arc of motion was 88°(800-1000. One patient had ulnar nerve neuropraxia and another patient developed median nerve neuropraxia, and both recovered completely in six weeks. No patient had symptomatic instability of the elbow. All patients were asymptomatic except one patient, who had pain mainly on heavy activities. Conclusion We conclude that inverted 'V' osteotomy excision arthroplasty is a viable option in the treatment of bony ankylosis of the elbow in young patients.

    To determine prognostic factors for and compare outcome among dogs with oral malignant melanoma following excision with or without various systemic adjuvant therapies. Retrospective case series. 151 dogs with naturally occurring oral malignant melanomas treated by excision with or without adjuvant therapies from 2001 to 2012. Case accrual was solicited from Veterinary Society of Surgical Oncology members via an email list service. Information collected from case records included signalment, tumor staging, tumor characteristics, type of surgical excision, histologic diagnosis, adjuvant therapy, and survival time. The overall median survival time was 346 days. Results of multivariate analysis indicated that tumor size, patient age, and intralesional excision (vs marginal, wide, or radical excision) were considered poor prognostic indicators. All other demographic and clinical variables were not significantly associated with survival time after adjusting for the aforementioned 3 variables. A clear survival benefit was not evident with any systemic adjuvant therapy, including vaccination against melanoma or chemotherapy; however, the number of dogs in each treatment group was small. Ninety-eight dogs received no postoperative adjuvant therapy, and there was no difference in survival time between dogs that did (335 days) and did not (352 days) receive systemic adjuvant therapy. For dogs with oral malignant melanoma, increasing tumor size and age were negative prognostic factors. Complete excision of all macroscopic tumor burden improved survival time. Long-term survival was possible following surgery alone. Although systemic adjuvant therapy was not found to improve survival time, this could have been due to type II error.

  17. Oncoplastic breast conserving surgery with tailored needle-guided excision. (United States)

    Hernanz, Fernando; González-Noriega, Mónica; Sánchez, Sonia; Paz, Lucia; Muñoz, Pedro; Hermana, Sandra


    Breast conserving surgery (BCS) administered with oncoplastic approach (OBCS), when it is required, is currently the gold standard for the treatment of early breast cancer. Wire-guided localization (WL) is the most popular technique used to help surgeon in breast cancer excision. Currently, a universal and undeniable goal is to minimize the rate of positive margins and re-excision operation after BCS improving cosmetic outcome and decreasing health care costs. This study is aimed to report our experience combining OBCS and tailored WL as surgical approach for early breast cancers. We performed a retrospective study on 148 breast cancer patients who were treated with OBCS and tailored WL, which consists in individualization of the number and location of wires depending on patient particularities, in our Breast Unit from March 2013 to December 2015. A multivariate analysis was used to determine the association between clinic-pathologic variables, which can be known preoperatively, and margin status. The rate of affected margins was 13.5% and 10.8% patients underwent re-interventions for oncologic reasons. Multifocality was strongly associated with involved margins [odds ratio (OR) 4.67]. OBCS together with tailored WL obtains an acceptable rate of positive margins and high rate of final BCS.

  18. Transaxillary Subcutaneouscopic Excision of Fibroadenoma of the Breast in Children: The Covert Scar Approach. (United States)

    Gonzalez, Mirtha; Pimpalwar, Ashwin


    Fibroadenoma is a common condition in adolescent girls. Most tumors are excised either through a periareolar approach or the inframammary approach. Both approaches produce visible scars in adolescent girls. We propose a new cosmetic approach to this lesion and report our experience with the transaxillary subcutaneouscopic approach for excision of the fibroadenoma of the breast. The purpose of this case report is to delineate an innovative surgical approach to resection of a breast fibroadenoma that yields an adequate resection without possible damage to the ductal system while optimizing cosmetic results by avoiding scars. We retrospectively reviewed the medical records of four adolescent girls who underwent the above approach for excision of fibroadenoma of the breast. The age range was 14-16 years. There were no complications in all 4 patients. The final result at the 3-month follow-up revealed an esthetically pleasing skin incision that healed well and was hidden by the natural skin fold of the axilla. Transaxillary subcutaneouscopic excision of fibroadenoma of the breast in children is a safe and effective technique and should be considered for excision of benign breast lesions in children.

    Gambichler, T; Senger, E; Rapp, S; Alamouti, D; Altmeyer, P; Hoffmann, K


    Shave excision is an established surgical method for removing benign skin lesions for cosmetic and functional reasons. Usually superficial shave excision is performed with a common scalpel blade for the removal of papular nevi. However, there is little known about deep shave excision of macular melanocytic nevi with the razor blade technique. The present study was undertaken to evaluate the cosmetic outcome of deep shave excision of macular melanocytic nevi with the razor blade technique. Moreover, its potency for sufficient removal of these lesions was investigated. Within routine skin cancer screening 45 outpatients with a total of 77 macular melanocytic nevi were prospectively recruited. Deep shave excisions of these lesions were performed with a double-edged razor blade followed by chemical hemostasis. Histologically all specimens were processed and evaluated in a routine manner. After 6 months the physician and patients evaluated the shave sites for cosmetic outcome with a score graded from 1 to 4 (1 = excellent; 2 = good; 3 = moderate; 4 = poor). Histologically 88% (68 of 77) of the melanocytic lesions were described as completely excised and 60% (46 of 77) were diagnosed as atypical melanocytic nevi; 12% (9 of 77) of the nevi were incompletely excised on the depth. On average, the deep margin of the specimens (n = 77) was 0.5 mm (range 0-1.8 mm) and the lateral margin was 2 mm (range 0.3-8.2 mm). After 6 months 56 shave sites could be reassessed. We observed mild hypopigmentation in 52% (29 of 56), hyperpigmentation in 32% (18 of 56), and erythema in 23% (13 of 56). Recurrent nevi occurred in 13% (7 of 56). The evaluation of the cosmetic outcome by the patients (mean score 1.7) achieved better results than the evaluation by the physician (mean score 2.5). The cosmetic results showed no significant (P >.05) differences in various anatomic sites. Our data confirm that deep razor blade excision presents a highly useful and inexpensive method for the removal of

    Full Text Available Introduction: This report presents a case of anorectal malignant melanoma treated with combined laparoscopic abdomino-endoscopic perineal total mesorectal excision. Presentation of case: An 82-year-old female presented with hematochezia. Colonoscopy revealed a 5-cm tumor in the anorectal junction, and biopsy specimen showed malignant melanoma. Modified ransanal total mesorectal excision was performed to get the sufficient surgical resection margins. After lymph node dissection in usual manner, mobilizing the rectum to the level of levator ani muscle. Then a skin incision was made around the anus and the transperineal access platform was placed. The fat tissue of the ischioanal fossa was divided until the levator ani muscle was exposed. The oral side of the colon was transected and specimen was extracted through the perineal incision site. Then stoma was placed laparoscopically. Discussion: This procedure provides not only better exposure of the extralevator surgical field, but also efficient resection margins compared with the conventional andominoperineal resection. Conclusion: To the best of our knowledge, this is the first report of combined laparoscopic abdomino-endoscopic perineal total mesorectal excision for anorectal malignant melanoma. Our experience showed safety and feasible option for anorectal malignant diseases.

    Full Text Available Correct surgical therapy considers radical excision of tumor formation, what can be certificated by absence of tumor cells on histopathological specimen margins.The aim of this investigation is to estimate incidence of presence of tumor cells on histopathological specimen margins in cases of intraoral carcinomas, surgically excised in macroscopically normal tissue with different wideness of normal tissue zone and relation to postoperative survival of this patients with intraoral carcinomas.Fifty seven patients with intraoral carcinomas were divided in three groups according to wideness of zone of excision in macroscopically normal tissue. Lowest percent of presence of tumor cells on margins of histopathological specimens were in group of patients with zone of excision behind zone of indurations of soft tissue, but patients from this group had shortest postoperative survival period. Presence of tumor cells on margins of histopathological specimens of excided intraoral carcinomas was found in high number of 81,07%.It can be said that presence of tumor cells on margins of histopathological specimens of exceeded intraoral carcinomas was found in extremely high number of 81,07%, but direct statistical significant relation in-between wideness of surgical excision and postoperative survival period was not found what show that another factors connected with postoperative survival of this patients must be examine.

    Pareja, Fresia; Corben, Adriana; Brennan, Sandra; Murray, Melissa P.; Bowser, Zenica; Jakate, Kiran; Sebastiano, Christopher; Morrow, Monica; Morris, Elizabeth; Brogi, Edi


    Background The surgical management of breast intraductal papilloma without atypia (IDP) identified at core needle biopsy (CNB) is controversial. We assessed the rate of upgrade to carcinoma at surgical excision, and identified parameters predictive of upgrade. Methods We identified women with CNB diagnosis of intraductal papilloma without atypia or carcinoma at our center between 2003 and 2013. Radiologic-pathologic concordance was assessed for all cases, and discordant cases were excluded. We correlated the radiologic and clinicopathologic features of patients with CNB diagnosis of IDP with upgrade to carcinoma at surgical excision. Results Our study population consists of 189 women with 196 IDPs; 166 women (171 IDPs) underwent excision. The upgrade rate was 2.3% (4/171). The upgrade lesions were 2 invasive lobular carcinomas and 2 cases of ductal carcinoma in situ (DCIS). One case of DCIS involved the residual IDP, whereas the other 3 carcinomas were ≥8 mm away. Twenty-four women (25 IDPs) did not undergo excision, and had stable imaging at follow-up (median of 23.5 months). Conclusions The upgrade rate at excision of IDP diagnosed at CNB with radiologic-pathologic concordance is 2.3%. Our findings suggest that observation is appropriate for patients with radiologic-pathologic concordant CNB yielding IDP, regardless of its size. PMID:27315013

    To determine the overall long-term postoperative clinical and functional results of high-level amateur athletes after hook of hamate excision, based on complications; return to sport; Disabilities of the Arm, Shoulder, and Hand (DASH) score; and a self-reported questionnaire. We evaluated 11 patients representing 12 cases of hook of hamate excision. All patients were high-level amateur athletes (rising collegiate or collegiate level). We performed a retrospective chart review to elicit information pertaining to the patient's injury. We assessed long-term postoperative outcomes with a self-reported questionnaire, the DASH form, and the DASH Sport/Performing Arts Module form. All patients successfully returned to full participation in their respective sports an average of 6 weeks after surgery. The average postoperative DASH score was less than 1, and all patients scored a 0 on the DASH Sports form. There was a significant improvement in preoperative pain after surgical intervention. There was no significant difference between preinjury and postoperative performance scores. Finally, every patient was very satisfied with the surgical outcome. There was only 1 postoperative complication in which a patient developed transient ulnar nerve paresthesias, which completely resolved by 6 weeks after surgery. Surgical excision of hook of hamate fractures in high-level amateur athletes allows for successful return to sports participation at preinjury performance levels, achievement of normal function as measured by validated objective outcome measures, significant reduction in pain, and high overall patient satisfaction. We consider surgical excision to be a safe and effective technique to restore normal function and hasten return to play for high-level amateur athletes. Therapeutic IV.

    Full Text Available Carotid body tumours are rare tumours arising from chemoreceptor cells at the bifurcation of carotid artery. They are highly vascular and mostly benign but with potential to turn into malignancy. Even though tumours are nearly always non functional, catecholamineproducing tumours do exist and can produce paroxysmal hypertension. As surgical removal is the commonest mode of treatment, anaesthetic management poses several challenges. Here we report a case of carotid body tumour excision with an eventful perioperative course.

    Full Text Available Introduction: Treatment of oral melanomas utilizes the surgical excision-resection (Culp et al., 2013 and/or radiation therapy (Proulx et al., 2003, chemotherapy with carboplatin (Brockley et al., 2013, immunotherapy (Ottnod et al., 2013. Treatment based on surgical excision is usually palliative (Freeman et al., 2003. Aims: In the literature even though there are data concerning the prognosis of oral melanomas in dogs after surgery, are missing data after laser excision. Taking into account these findings we wished to present our experience regarding three cases of oral melanoma recurrence and immediate and long term laser surgery results. Materials and Methods: The casuistry consisted of three dogs with recurrent oral malignant melanomas, subjected to surgical reintervention. The initial diagnosis was melanotic melanoma in stage I or II. The animals were brought back at different time intervals from originally excision with electric scalpel. Before reintervention, dogs were subjected to clinical, paraclinical exam and biopsy. Excision of the tumor mass was made with an optical fiber hawing a diameter of 400µm, at a power of 10W and a wavelength of 940 nm with a diode laser. At 1, 2, 3, 6 and 12 months after laser reintervention the dogs were reexamined. Results: Average time in which appeared canine oral melanoma relapse was 58.6 days. After reexamination all cases where reinstatement in stage I. Operators times were held in conditions of comfort with wide access, minimum bleeding, effective hemostasis. After surgery at 24 hours on the intervention place a slight local redness, without swelling and bleeding was observed. Palpation revealed initially also a slight local sensitivity which completely disappeared in 48 hours. There were no grasping and chewing disturbances. Macroscopic healing occurred in 7-9 days. At last recheck performed at 12 months there were no evidences of tumour recurrence or metastasis. Conclusion: Diode laser excision

  12. Method and device for intraoperative imaging of lumpectomy specimens to provide feedback to breast surgeon for prompt re-excision during the same procedure (United States)

    Krol, Andrzej; Hemingway, Susan; Kort, Kara; de la Rosa, Gustavo; Adhikary, Ravi; Masrani, Deepa; Feiglin, David; O'Connell, Avice; Nagarajan, Mahesh; Yang, Chien-Chun; Wismüller, Axel


    Breast conserving therapy (BCT) of breast cancer is now widely accepted due to improved cosmetic outcome and improved patients' quality of life. One of the critical issues in performing breast-conserving surgery is trying to achieve microscopically clear surgical margins while maintaining excellent cosmesis. Unfortunately, unacceptably close or positive surgical margins occur in at least 20-25% of all patients undergoing BCT requiring repeat surgical excision days or weeks later, as permanent histopathology routinely takes days to complete. Our aim is to develop a better method for intraoperative imaging of non-palpable breast malignancies excised by wire or needle localization. Providing non-deformed three dimensional imaging of the excised breast tissue should allow more accurate assessment of tumor margins and consequently allow further excision at the time of initial surgery thus limiting the enormous financial and emotional burden of additional surgery. We have designed and constructed a device that allows preservation of the excised breast tissue in its natural anatomic position relative to the breast as it is imaged to assess adequate excision. We performed initial tests with needle-guided lumpectomy specimens using micro-CT and digital breast tomosynthesis (DBT). Our device consists of a plastic sphere inside a cylindrical holder. The surgeon inserts a freshly excised piece of breast tissue into the sphere and matches its anatomic orientation with the fiducial markers on the sphere. A custom-shaped foam is placed inside the sphere to prevent specimen deformation due to gravity. DBT followed by micro-CT images of the specimen were obtained. We confirmed that our device preserved spatial orientation of the excised breast tissue and that the location error was lower than 10mm and 10 degrees. The initial obtained results indicate that breast lesions containing microcalcifications allow a good 3D imaging of margins providing immediate intraoperative feedback for

    Objective To estimate the effectiveness and safety of laparoscopic surgical excision of rectovaginal endometriosis. Design A multicentre, prospective cohort study. Setting 51 hospitals accredited as specialist endometriosis centres. Participants 5162 women of reproductive age with rectovaginal endometriosis of which 4721 women had planned laparoscopic excision. Interventions Laparoscopic surgical excision of rectovaginal endometriosis requiring dissection of the pararectal space. Main outcome measures Standardised symptom questionnaires enquiring about chronic pelvic pain, bladder and bowel symptoms, analgesia use and quality of life (EuroQol) completed prior to surgery and at 6, 12 and 24 months postoperatively. Serious perioperative and postoperative complications including major haemorrhage, infection and visceral injury were recorded. Results At 6 months postsurgery, there were significant reductions in premenstrual, menstrual and non-cyclical pelvic pain, deep dyspareunia, dyschezia, low back pain and bladder pain. In addition, there were significant reductions in voiding difficulty, bowel frequency, urgency, incomplete emptying, constipation and passing blood. These reductions were maintained at 2 years, with the exception of voiding difficulty. Global quality of life significantly improved from a median pretreatment score of 55/100 to 80/100 at 6 months. There was a significant improvement in quality of life in all measured domains and in quality-adjusted life years. These improvements were sustained at 2 years. All analgesia use was reduced and, in particular, opiate use fell from 28.1% prior to surgery to 16.1% at 6 months. The overall incidence of complications was 6.8% (321/4721). Gastrointestinal complications (enterotomy, anastomotic leak or fistula) occurred in 52 (1.1%) operations and of the urinary tract (ureteric/bladder injury or leak) in 49 (1.0%) procedures. Conclusion Laparoscopic surgical excision of rectovaginal endometriosis

  17. Staged Soft Tissue Reconstruction Following Sarcoma Excision with Anticipated Large Cutaneous Defects: An Oncologically Safe Alternative (United States)

    Siegel, Geoffrey W; Kuzon, William M.; Hasen, Jill M; Biermann, J. Sybil


    Background We hypothesized that select patients undergoing planned soft tissue sarcoma (STS) excision with anticipated skin and soft tissue deficits could be treated with a two stage surgical procedure which would allow some flexibility in coverage options while not significantly increasing local recurrence rate or wound complication rate. Methods A retrospective review was undertaken in a series of consecutive patients with a minimum 2-year follow-up treated by a single orthopedic oncologist and a single reconstructive plastic surgeon who were managed with a staged approach STS excision and reconstruction. Results There were 73 patients identified over a ten-year period that underwent staged STS excision and soft tissue reconstruction. There were 12 (16%) initial positive margins resected to negative final margins, and a variety of coverage procedures performed. Wound complication rate was 21%. Local recurrence rate was 11%. Conclusion Staged STS excision and reconstruction is an acceptable tool in the armamentarium of the orthopedic oncologist for managing major soft tissue deficits without an increase in local recurrence rates.

  18. Excision versus trichloroacetic acid (TCA) chemocauterization for branchial sinus of the pyriform fossa. (United States)

    Hwang, Jihee; Kim, Seong Chul; Kim, Dae Yeon; Namgoong, Jung-Man; Nam, Soon Yuhl; Roh, Jong-Lyel


    We analyzed the outcomes of open surgical excision and endoscopic trichloroacetic acid (TCA) chemocauterization for the treatment of branchial sinus of the pyriform fossa (BSPF). We retrospectively reviewed the records of 27 patients (16 males and 11 females) who were treated for BSPF at the Asan Medical Center between 1996 and 2013. The median age of the 27 patients was 4.5years (range, 0 to 15years). Before definitive surgery, 19 (70.3%) of the patients had histories of neck infection, and 16 (59.2%) patients had neck abscesses that were drained. The lesions were predominantly located on the left side (26 of 27; 96.2%). Excisions were performed for 14 (48.1%) patients. TCA chemocauterizations were performed for 13 patients. After a median follow-up period of 5.5years, 11 patients developed recurrence. The recurrence rates were not significantly different between the excision and chemocauterization groups (35.7% vs 46.1%, respectively, p=0.704). All of the recurred patients were successfully treated with repeated chemocauterization or reexcision. Analyses of the risk factors for recurrence revealed that a previous infection history tended to increase the rate of recurrence (90.9% vs 56.2%, p=0.090). Our experience suggests that the outcomes of excision and TCA chemocauterization are not significantly different. Additional studies are needed to reach a consensus regarding the best treatment strategy for BSPF. Copyright © 2015 Elsevier Inc. All rights reserved.

    Murat Korkmaz


    Full Text Available Background: Ingrown toenails (IT is a very common problem leading to significant associated morbidity. The articles related to phenolization for matrix removal in teenagers with IT are not enough in the foot surgery literature. Aims: To compare the postoperative recovery periods, complication rate, and tolerability of partial matrix excision and segmental phenolization in teenagers with IT. Materials and Methods: Thirty-nine patients (13-17 years with 48 IT were randomly divided into two groups and were treated with partial matrix excision (Group I and segmental phenolization (Group II. We assessed the recurrence rates, postoperative complications, duration of analgesic usage, and time to return to daily activities. Results: There was no significant difference between the demographic and clinical data of the two groups. Three patients in Group I and two patients in Group II experienced moderate pain postoperatively. These patients used analgesics for 3 days. The rates of postoperative complications and recurrences between the two groups showed no statistically significant difference ( P = 0.688. The time to return to normal daily activities was significantly shorter in Group II patients than in Group I patients ( P < 0.05. Conclusions: Partial matrix excision is a very safe model of therapy in the surgical treatment of teenagers with IT. It has low recurrence rate and minimal postoperative morbidity. We concluded that segmental phenolization is also as safe as partial matrix excision in the treatment of IT and patients return to their daily activities in less time with this treatment modality.

  20. Pleomorphic adenomas: post-operative radiotherapy is unnecessary following primary incomplete excision: a retrospective review. (United States)

    Robertson, B F; Robertson, G A; Shoaib, T; Soutar, D S; Morley, S; Robertson, A G


    Current standard treatment of Pleomorphic Salivary Adenoma (PSA) of the Parotid Gland is by surgical excision. The management of incomplete excision remains undecided with post-operative radiotherapy advocated by some and observation by others. 190 patients who underwent resection of PSA of the parotid gland within the West of Scotland region from 1981 to 2008 were identified and data collected. 78/190 patients had a primary incomplete excision. 25/78 received post-operative radiotherapy and 53 were observed. Recurrences occurred in 11/53 in those observed and in 1/25 of those who received radiotherapy. 21/25 complained of significant side effects from the radiotherapy. 38 surgeons performed 190 procedures, with a range of experience from 1 to28 procedures. Radiotherapy does appear to reduce recurrence with incomplete excision, however it is associated with significant side effects. We therefore feel radiotherapy should not be routinely recommended. Subspecialisation should be adopted to increase the operating surgeon's experience. Copyright © 2014 British Association of Plastic, Reconstructive and Aesthetic Surgeons. Published by Elsevier Ltd.

  1. Keratoacanthoma centrifugum marginatum: unresponsive to oral retinoid and successfully treated with wide local excision.

    Directory of Open Access Journals (Sweden)

    Kapildev Das


    Full Text Available We describe a case of a 65-year-old male presenting with a large plaque with a rolled-out interrupted margin, atrophic center, and island of normal skin over the left arm. It grew peripherally with central healing, and there was a history of recurrence after inadequate excision. Investigations ruled out other clin­ical mimickers; namely, squamous cell carcinoma, lupus vulgaris, botryomycosis, and blastomycosis-like pyoderma. Histopathological sections showed irregularly shaped craters filled with keratin and epithelial pearl but no evidence of granuloma or cellular atypia. Clinico­pathological correlation proved the lesion to be keratoacanthoma centrifugum marginatum (KCM, a rare variant of keratoacanthoma, which spreads centrifugally, attains a huge size, and never involutes spontaneously. Treatment of KCM has been a problem always and, in our case, systemic retinoid (acitretin for three months proved ineffective. The patient also had a history of recurrence following surgical intervention previously, necessitating wide excision to achieve complete clearance of tumor cells. Hence, after failure of retinoid therapy, the decision of excision with a 1-centimeter margin was taken and the large defect was closed by a split thickness skin graft. The graft uptake was satisfactory, and the patient is being followed-up presently and shows no signs of recurrence after six months, highlighting wide local excision as a useful treatment option.

    Full Text Available AIM:To find the risk factors related to the reproliferation of the pterygial tissue after excision and graft surgery.METHODS:Charts of 130 eyes of 130 patients who had pterygial excision from March 2006 to April 2011 were reviewed. Preoperative pterygium morphology, surgical methods, and adjunctive treatments were statistically analyzed for their relationship with recurrence.RESULTS: During the follow-up period, recurrence was observed in 20 eyes (15.4%. None of the preoperative morphologic features were affected the rate of the recurrence. However, an age < 40y [P =0.085, odds ratio (OR 3.609, 95% confidence interval (CI 0.838-15.540] and amniotic membrane graft instead of conjunctival autograft (P =0.002, OR 9.093, 95% CI 2.316-35.698 were statistically significant risk factors for recurrence. Multivariate analysis revealed that intraoperative mitomycin C (MMC (P=0.072, OR 0.298, 95% CI 0.080-1.115 decreased the rate of recurrence.CONCLUSION:Younger age is a risk factor for reproliferation of pterygial tissue after excision and amniotic membrane transplantation (AMT are less effective in preventing recurrence of pterygium after excision based on the comparison between conjunctival autograft and AMT. Intraoperative MMC application and conjunctival autograft reduce recurrence.

    Libby R. Copeland-Halperin


    Full Text Available Background. Lipomas are benign tumors of mature fat cells. They can be removed by liposuction, yet this technique is seldom employed because of concerns that removal may be incomplete and recurrence may be more frequent than after conventional excision. Objectives. We assessed the short- and long-term clinical outcomes and recurrence of combined liposuction and limited surgical excision of subcutaneous lipomas. Methods. From 2003 to 2012, 25 patients with 48 lipomas were treated with liposuction followed by direct excision through the same incision to remove residual lipomatous tissue. Initial postoperative follow-up ranged from 1 week to 3 months, and long-term outcomes, complications, and recurrence were surveyed 1 to 10 years postoperatively. Results. Lipomas on the head, neck, trunk, and extremities ranged from 1 to 15 cm in diameter. Early postoperative hematoma and seromas were managed by aspiration. Among 23 survey respondents (92%, patients were uniformly pleased with the cosmetic results; none reported recurrent lipoma. Conclusions. The combination of liposuction and excision is a safe alternative for lipoma removal; malignancy and recurrence are uncommon. Liposuction performed through a small incision provides satisfactory aesthetic results in most cases. Once reduced in size, residual lipomatous and capsular tissue can be removed without expanding the incision. These favorable outcomes support wider application of this technique in appropriate cases.

  4. Combined excision and intralesional bevacizumab for sebaceous carcinoma of the eyelid in an Amur tiger (Panthera tigris altaica). (United States)

    Edelmann, Michele L; Utter, Mary L; Klein, Lin V; Wotman, Kathryn L


    An 18-year-old zoo-kept female Amur tiger presented with an approximately 5 mm diameter lateral canthal eyelid mass in the left eye which grossly appeared red and irregular. The mass was completely excised via lateral canthoplasty. Histopathologic evaluation was consistent with a diagnosis of sebaceous cell carcinoma, which is a potentially aggressive cutaneous neoplasm. The sebaceous carcinoma recurred within 3 months and slowly increased in size until a second surgical excision was performed 9 months following the first surgery. The second surgical excision was combined with intralesional injection of 10 mg of the antiangiogenic drug bevacizumab. Histology confirmed the diagnosis. The tiger was euthanized 16 months postoperatively for reasons unrelated to, and without recurrence of, the eyelid neoplasm. At postmortem, no gross periocular or metastatic lesions were noted, and histopathology of the lateral canthus provided no evidence of recurrence. Surgical excision combined with intralesional bevacizumab treatment induced life-long resolution of the sebaceous carcinoma. Bevacizumab treatment may be associated with the regression of periocular angiogenic proliferative conditions, including neoplasia, by inhibiting angiogenesis. © 2012 American College of Veterinary Ophthalmologists.

  5. Multidirectional Vector Excision Leads to Better Outcomes than Traditional Elliptical Excision of Facial Congenital Melanocytic Nevus

    Directory of Open Access Journals (Sweden)

    Seung Il Oh


    Full Text Available Background The elliptical excision is the standard method of removing benign skin lesions,such as congenital melanocytic nevi. This technique allows for primary closure, with little to nodog-ear deformity, but may sacrifice normal tissue adjacent to the lesion, resulting in scarswhich are unnecessarily long. This study was designed to compare the predicted results ofelliptical excision with those resulting from our excision technique.Methods Eighty-two patients with congenital melanocytic nevus on the face were prospectivelystudied. Each lesion was examined and an optimal ellipse was designed and marked onthe skin. After an incision on one side of the nevus margin, subcutaneous undermining wasperformed in the appropriate direction. The skin flap was pulled up and approximated alongseveral vectors to minimize the occurrence of dog-ear deformity.Results Overall, the final wound length was 21.1% shorter than that achieved by ellipticalexcision. Only 8.5% of the patients required dog-ear repair. There was no significant distortionof critical facial structures. All of the scars were deemed aesthetically acceptable based ontheir Patient and Observer Scar Assessment Scale scores.Conclusions When compared to elliptical excision, our technique appears to minimize dogeardeformity and decrease the final wound length. This technique should be considered analternative method for excision of facial nevi.

  6. Soft-tissue nail-fold excision: a definitive treatment for ingrown toenails (United States)

    Chapeskie, Henry; Kovac, Jason R.


    Background Ingrown toenail, or onychocryptosis, is a common source of morbidity worldwide. The current standard of care focuses on the nail as the causative agent, and, in cases that are resistant to medical management, surgical correction via nail avulsion and phenol matrix ablation is used. Unfortunately, this treatment leads to poor cosmetic results, high rates of recurrence and low patient satisfaction. Methods We retrospectively reviewed a case series of 124 consecutive patients who underwent surgical correction of ingrown toenails from 1988 to 2004. We recorded the operative technique and postoperative wound healing via photographs. We assessed outcomes and patient satisfaction using self-reports and 7-point Likert scale questionnaires. Results Our surgical approach involved the excision of excessive nail-fold granulation tissue with preservation of the nail and its matrix. In total, 72.5% of patients were under the age of 29 (69.4% men). Before surgical intervention, 78.8% of patients scored their pain as severe, 69.9% had difficulty wearing normal footwear and 64.3% had difficulty with normal activities because of their ingrown toenails. A total of 212 surgical sites were analyzed, with a median follow-up of 8 years. No recurrences were identified in any patients (100%, n = 124). Overall, 94.3% (n = 116) stated that they were highly satisfied with the procedure. Only 1.6% (n = 2) reported a loss of sensation at the surgical site. Conclusion Surgical correction of ingrown toenails via soft-tissue excision of the nail folds, coupled with preservation of the nail and its matrix, had excellent cosmetic results, no recurrences and high rates of patient satisfaction.

    Pelizzone, Igor; Vitolo, Gaetano D; D'Acierno, Massimo; Stefanello, Damiano; Forlani, Annalisa; Broich, Guido


    To describe our experience with lateral approach for excision of maxillary pseudo-odontomas and to illustrate surgical outcomes and postoperative complications in seven pet prairie dogs. Excision of 11 maxillary pseudo-odontomas was performed in seven prairie dogs with a lateral approach technique and clinical presentation, duration of surgery, time and type of post-surgical complications, presence or absence of symptom recurrence, time to follow-up, overall survival time and causes of death of each case were recorded. Duration of surgery, postoperative hospitalization and time to autonomous feeding were 54.8 min, 58 h and 1 day, respectively. Recurrence of respiratory symptoms was observed in four cases. Mean follow-up time was 632 days. Six out of seven cases were still alive at the end of the study. The lateral approach to excision showed good and promising results for treatment of maxillary pseudo-odontomas in prairie dogs.

  8. Characteristics of 64 sarcoma patients referred to a sarcoma center after unplanned excision. (United States)

    Dyrop, Heidi Buvarp; Safwat, Akmal; Vedsted, Peter; Maretty-Kongstad, Katja; Hansen, Bjarne Hauge; Jørgensen, Peter Holmberg; Baad-Hansen, Thomas; Keller, Johnny


    Unplanned excision of sarcoma before referral to specialist centers can affect prognosis and surgical outcome. The diagnostic pathway of these patients is uncertain and needs to be reviewed. We aimed to describe patient and tumor characteristics, initial symptoms, initial and final diagnosis, and explore reasons for unplanned excision in this patient group. From a previous study on 258 sarcoma patients, we identified 64 patients referred after surgery. Medical records were reviewed. The majority were soft tissue sarcomas, most often with thoracic location. Leiomyosarcoma was the most frequent final diagnosis, lipoma, and fibroma/dermatofibroma the most frequent initial diagnoses. Fifty percent were superficial small tumors, and 60.9% had not received diagnostic imaging before surgery. Fifty percent were referred from public surgical departments, and 1/3 from private specialists. Twenty-three patients had initial presence of alarm symptoms registered before surgery, the remaining 2/3 fell outside referral criteria or alarm symptoms were not discovered. Patients referred after unplanned excision often have small superficial tumors and the majority fall outside of defined referral criteria. Referral criteria are not a guarantee for detection of all sarcomas and surgeons should always be aware of the possibility of malignancy when removing a tumor. © 2016 Wiley Periodicals, Inc.

  9. Antihistaminic and cardiorespiratory effects of diphenhydramine hydrochloride in anesthetized dogs undergoing excision of mast cell tumors. (United States)

    Sanchez, Andrea; Valverde, Alexander; Sinclair, Melissa; Mosley, Cornelia; Singh, Ameet; Mutsaers, Anthony J; Hanna, Brad; Johnson, Ron; Gu, Yu; Beaudoin-Kimble, Michelle


    OBJECTIVE To evaluate the effects of IV diphenhydramine hydrochloride administration on cardiorespiratory variables in anesthetized dogs undergoing mast cell tumor (MCT) excision. DESIGN Randomized, blinded clinical trial. ANIMALS 16 client-owned dogs with MCTs. PROCEDURES In a standardized isoflurane anesthesia session that included mechanical ventilation, dogs received diphenhydramine hydrochloride (1 mg/kg [0.45 mg/lb], IV; n = 8) or an equivalent volume of saline (0.9% NaCl) solution (IV; control treatment; 8) 10 minutes after induction. Cardiorespiratory variables were recorded throughout anesthesia and MCT excision, and blood samples for determination of plasma diphenhydramine and histamine concentrations were collected prior to premedication (baseline), throughout anesthesia, and 2 hours after extubation. RESULTS Cardiorespiratory values in both treatment groups were acceptable for anesthetized dogs. Mean ± SD diastolic arterial blood pressure was significantly lower in the diphenhydramine versus control group during tumor dissection (52 ± 10 mm Hg vs 62 ± 9 mm Hg) and surgical closure (51 ± 10 mm Hg vs 65 ± 9 mm Hg). Mean arterial blood pressure was significantly lower in the diphenhydramine versus control group during surgical closure (65 ± 12 mm Hg vs 78 ± 11 mm Hg), despite a higher cardiac index value. Plasma histamine concentrations were nonsignificantly higher than baseline during maximal manipulation of the tumor and surgical preparation in the diphenhydramine group and during surgical dissection in the control group. CONCLUSIONS AND CLINICAL RELEVANCE IV administration of diphenhydramine prior to MCT excision had no clear clinical cardiorespiratory benefits over placebo in isoflurane-anesthetized dogs.

  11. Robot-Assisted Excision of a Retroperitoneal Mass Between the Left Renal Artery and Vein (United States)

    Lehrfeld, Todd; Natale, Rachel; Sharma, Saurabh; Mendoza, Pierre J.; Schwab, Charles W.


    Background: Extra-adrenal pheochromocytomas are rare. Minimally invasive techniques have been utilized for incidentally discovered masses with successful results. Methods: We present a case of a 64-year-old female with a 3.5-cm mass located between her left renal artery and vein, treated by a 4-port robot-assisted transperitoneal laparoscopic approach. Results: Careful dissection of the tumor away from the renal hilum was accomplished without major vascular injury. A pedicle to the tumor was identified and ligated. The pathology demonstrated a benign pheochromocytoma. To our knowledge, this is the first report of a peri-hilar excision of a pheochromocytoma using this approach. Conclusion: Extra-adrenal pheochromocytomas are rare and can present in difficult locations. While surgical excision may be challenging, the da Vinci Robot may be used effectively and safely for the treatment of these perihilar masses. PMID:21333207

  12. The impact of use of an intraoperative margin assessment device on re-excision rates. (United States)

    Sebastian, Molly; Akbari, Stephanie; Anglin, Beth; Lin, Erin H; Police, Alice M


    Historically there has been a high rate of surgical interventions to obtain clear margins for breast cancer patients undergoing breast conserving local therapy. An intraoperative margin assessment tool (MarginProbe) has been approved for use in the US since 2013. This study is the first compilation of data from routine use of the device, to assess the impact of device utilization on re-excision rates. We present a retrospective, observational, review from groups of consecutive patients, before and after the implementation of intraoperative use of the device during lumpectomy procedures. Lesions were localized by standard methods. The intraoperative margin assessment device was used on all circumferential margins of the main specimen, but not on any additional shavings. A positive reading by the device led to an additional shaving of the corresponding cavity location. Specimens were also, when feasible, imaged intra-operatively by X-ray, and additional shavings were taken if needed based on clinical assessment. For each surgeon, historical re-excision rates were established based on a consecutive set of patients from a time period proximal to initiation of use of the device. From March 2013 to April 2014 the device was routinely used by 4 surgeons in 3 centers. In total, 165 cases lumpectomy cases were performed. Positive margins resulted in additional re-excision procedures in 9.7% (16/165) of the cases. The corresponding historical set from 2012 and 2013 consisted of 186 Lumpectomy cases, in which additional re-excision procedures were performed in 25.8% (48/186) of the cases. The reduction in the rate of re-excision procedures was significant 62% (P interest may include an analysis of the effect of using the device on the shavings intra-operatively.

  13. Performance and role of the breast lesion excision system (BLES) in small clusters of suspicious microcalcifications. (United States)

    Scaperrotta, Gianfranco; Ferranti, Claudio; Capalbo, Emanuela; Paolini, Biagio; Marchesini, Monica; Suman, Laura; Folini, Cristina; Mariani, Luigi; Panizza, Pietro


    To assess the diagnostic performance of the BLES as a biopsy tool in patients with ≤ 1 cm clusters of BIRADS 4 microcalcifications, in order to possibly avoid surgical excision in selected patients. This is a retrospective study of 105 patients undergone to stereotactic breast biopsy with the BLES. It excises a single specimen containing the whole mammographic target, allowing better histological assessment due to preserved architecture. Our case series consists of 41 carcinomas (39%) and 64 benign lesions (61%). Cancer involved the specimen margins in 20/41 cases (48.8%) or was close to them (≤ 1 mm) in 14 cases (34.1%); margins were disease-free in only 7 DCIS (17.1%). At subsequent excision of 39/41 malignant cases, underestimation occurred for 5/32 DCIS (15.6%), residual disease was found in 15/39 cancers (38.5%) and no cancer in 19/39 cases (48.7%). For DCIS cases, no residual disease occurred for 66.7% G1-G2 cases and for 35.3% G3 cases (P=0.1556) as well as in 83.3%, 40.0% and 43.8% cases respectively for negative, close and positive BLES margins (P=0.2576). The BLES is a good option for removal of small clusters of breast microcalcifications, giving better histological interpretation, lower underestimation rates and possibly reducing the need of subsequent surgical excision in selected patients.

  14. Supra-aural gossypiboma: case report of a retained textile surgical sponge in an unusual location. (United States)

    Chawla, N; Gupta, N; Dhawan, N


    Gossypiboma or retained surgical sponge is an infrequently encountered surgical complication, more so in the head and neck region. A literature search did not reveal a previously reported case of retained or concealed surgical sponge after microscopic ear surgery. We present a unique and previously unreported case of a 25-year-old male who presented with a cystic swelling in the right supra-aural region 5 months post-modified radical mastoidectomy of the right ear. Surgical excision of the swelling revealed a retained surgical sponge. We emphasise the importance of counting surgical sponges after every surgical step to minimise the incidence of such retained surgical items.

  15. Oncoplastic Breast-Conserving Surgery Reduces Mastectomy and Postoperative Re-excision Rates. (United States)

    Crown, Angelena; Wechter, Debra G; Grumley, Janie W


    Oncoplastic breast-conserving surgery (BCS) integrates partial mastectomy with plastic surgery techniques to facilitate breast cancer resection with clear surgical margins and preservation of breast cosmesis. In 2011, oncoplastic BCS was adopted as standard surgical treatment for breast cancer patients at Virginia Mason Medical Center, Seattle, WA. This single-institution retrospective review evaluates the mastectomy and postoperative re-excision rates before and after adoption of oncoplastic BCS. All patients undergoing surgical treatment of breast cancer were identified from institutional databases for the periods January 2009 through December 2010 [standard surgery group (SS)] and January 2013 through September 2014 [oncoplastic surgery group (OS)]. A total of 812 patients were evaluated; 425 patients were treated in the SS group compared with 387 patients in the OS group. The mastectomy rate in the SS group was 34% compared with 15% in the OS group (p Oncoplastic BCS significantly reduced the rates of mastectomy and postoperative re-excision in breast cancer patients while treating larger cancers. This study suggests that use of OS techniques can effectively treat larger cancers while maximizing breast cosmesis and minimizing the need to resort to mastectomy.

  16. Teaching elliptical excision skills to novice medical students: a randomized controlled study comparing low- and high-fidelity bench models. (United States)

    Denadai, Rafael; Oshiiwa, Marie; Saad-Hossne, Rogério


    The search for alternative and effective forms of training simulation is needed due to ethical and medico-legal aspects involved in training surgical skills on living patients, human cadavers and living animals. To evaluate if the bench model fidelity interferes in the acquisition of elliptical excision skills by novice medical students. Forty novice medical students were randomly assigned to 5 practice conditions with instructor-directed elliptical excision skills' training (n = 8): didactic materials (control); organic bench model (low-fidelity); ethylene-vinyl acetate bench model (low-fidelity); chicken legs' skin bench model (high-fidelity); or pig foot skin bench model (high-fidelity). Pre- and post-tests were applied. Global rating scale, effect size, and self-perceived confidence based on Likert scale were used to evaluate all elliptical excision performances. The analysis showed that after training, the students practicing on bench models had better performance based on Global rating scale (all P skills (all P 0.05) between the groups that trained on bench models. The magnitude of the effect (basic cutaneous surgery skills' training) was considered large (>0.80) in all measurements. The acquisition of elliptical excision skills after instructor-directed training on low-fidelity bench models was similar to the training on high-fidelity bench models; and there was a more substantial increase in elliptical excision performances of students that trained on all simulators compared to the learning on didactic materials.

    Alonso, S.; Arenas, J.; Fernandez, F.; Gil, S.; Guirau, M. D. [Hospital General Universitario de Alicante (Spain)


    The detailed radiological study of the anatomy of the nasal cavities and paranasal sinus is essential prior to endoscopic sinus surgery since, on the one hand, it discloses the extent of the disease and, on the other hand, it aids in the detection of the numerous anatomic variants, some of which are of great interest to the endoscopic as the lack of preoperative knowledge of them may increase the risk of complications. the objective of the present report is to review these variants, stressing those that may be associated with a greater surgical risk. Although coronal computed tomography is the technique of choice for pre endoscopy examination, certain structures and anatomic variants are better viewed in axial images. These exceptions include anterior and posterior walls of the frontal sinuses, the anatomic relationships between posterior ethmoid complex and the sphenoid sinus, the relationships between the sphenoid sinus and the optic nerve, and the detection of Onodi cells. Thus, we recommend that the radiological examination include both coronal and axial images. (Author) 16 refs.

  1. Total mesorectal excision training in soft cadaver: feasibility and clinical application. (United States)

    Tantiphlachiva, Kasaya; Suansawan, Channarong


    The major problem in the treatment of rectal cancer is local recurrence. After the introduction of total mesorectal excision (TME), the recurrent rate decreased from 100% to around 10%. The purpose of the present study was to evaluate the quality of organ and tissue plane preservation in soft cadaver and to assess the feasibility to perform the procedure (mobilization of colon and rectum, total mesorectal excision and stapler anastomosis) in soft cadaver. Colorectal Division, Department of Surgery and Surgical Training Center Department of Anatomy, Faculty of Medicine, Chulalongkorn University. Prospective descriptive study. Seven soft cadavers were used for total mesorectal excision (TME) training. These procedures were performed by 21 participants (1 soft cadaver for 3 participants). The procedures were done under the supervision of experienced colorectal surgeons. The successfulness, satisfaction in performing the procedure and the quality of organ preservation were evaluated using standardized questionnaires. Participants were satisfied about TME training in soft cadaver (mean 8.24-8.71) and rated that soft cadavers were good in terms of internal organs and tissue plane preservation (mean 7.19-8.19) (0 = extremely unsatisfied, 10 = extremely satisfied). Training of TME in soft cadaver is feasible. The similarity in tissue quality (texture, consistency, color) of the preserved organs to that of the living and the good feel of performing the procedure make the trainee better understand the techniques and improve their skills.

  2. Physical Therapy Rehabilitation of an Adolescent Preprofessional Dancer Following Os Trigonum Excision: A Case Report. (United States)

    Filipa, Alyson; Barton, Kelli


    Study Design Case report. Background An os trigonum can be a source of pain for dancers due to impingement during repetitive ankle plantar flexion movements. Following excision of an os trigonum, it is important to have a gradual, progressive return-to-dance program for optimal recovery. The purpose of this case report is to describe the postoperative management and return-to-dance progression of an adolescent dancer post os trigonum excision. Case Description An adolescent preprofessional female dancer had an extensive history of left posterior heel pain, beginning at age 8, that led to surgical removal of an os trigonum at age 15. Post surgery, the patient was seen for a total of 22 visits over the course of 20 weeks. Treatment included therapeutic exercises, neuromuscular re-education, and manual therapy. Return-to-dance tests and guidelines were used to safely progress to full, unrestricted dance participation. Outcomes The dancer had a full return of ankle range of motion, strength, and balance, improved patient-reported outcome scores, and was able to fully return to dance participation. Discussion Treating a dancer following os trigonum excision should involve a screen for hypermobility, clear communication with the dance instructor, awareness of dance-specific biomechanics, and proper reintegration into dance participation. Level of Evidence Therapy, level 5. J Orthop Sports Phys Ther 2018;48(3):194-203. Epub 7 Nov 2017. doi:10.2519/jospt.2018.7508.

  3. Intralesional excision with topical intralesional cryotherapy improves the treatment of keloid scarring in a paediatric patient. (United States)

    Reissis, D; Tickunas, T; Agha, R A; Greig, Avh


    Recurrent keloid scarring has a significant impact on quality of life. Management is complex, particularly for scars resistant to conventional treatments and in paediatric cases where radiotherapy is not a suitable adjunct to surgical excision. We present the case of a nine-year-old African Caribbean girl with multiple large and recurrent keloid scars on both ears and bilateral sensorineural deafness. Following repeated intralesional excisions, corticosteroid and botulinum toxin injections, she continued to experience rapid recurrence of her keloids, worsening pain and pruritus. She was no longer able to wear her hearing aids because of the large size of the keloids. We employed a novel technique using topical intralesional cryotherapy, applying liquid nitrogen intraoperatively to the inside of the skin flaps immediately post-intralesional keloid excision and before wound closure. At 26-month follow-up a good aesthetic and symptomatic result was achieved, with minimal hypopigmentation, significantly reduced scar volume and significantly slowed recurrence. We discuss this case and review the current literature on the use of topical intralesional cryotherapy for keloid scarring.

  4. Excision of a large abdominal wall lipoma improved bowel passage in a Proteus syndrome patient (United States)

    Nakayama, Yoshifumi; Kusuda, Shinichi; Nagata, Naoki; Yamaguchi, Koji


    Proteus syndrome is an extremely rare congenital disorder that produces multifocal overgrowth of tissue. This report presents a surgical case of a large lipoma in the abdominal wall of a patient with Proteus syndrome. She was diagnosed with Proteus syndrome based on certain diagnostic criteria. The neoplasm increased in size gradually, producing hemihypertrophy of her left lower extremity and trunk, and spread to her retroperitoneum and her left abdominal wall. She experienced gradually progressive constipation, nausea, vomiting, and abdominal pain. Computed tomography (CT) of the abdomen demonstrated a large mass in the subcutaneous adipose tissue of the left lower abdominal wall which measured 12 cm × 8 cm x 6 cm in diameter and encased the left colon. This mass in the abdominal wall was excised. The weight of the excised mass was 1550 g. The histopathological diagnosis of this mass was lipoma. After surgery, the encasement of the left colon was improved, and the patient was able to move her bowels twice per day. The excision of the large lipoma in the abdominal wall contributed to the improved bowel passage in this patient with Proteus syndrome. PMID:19598310

  5. Application of Mini-abdominoplasty after Conservative Excision of Extensive Cesarean Scar Endometriosis

    Directory of Open Access Journals (Sweden)

    Eui Tai Lee


    Full Text Available Endometriosis is defined as the presence of functioning endometrial tissue outside the uterine cavity, and the standard treatment is extensive surgical excision. Cesarean scar endometriosis is a type of cutaneous endometriosis arising on or near a Cesarean section scar. A 44-year-old woman presented with a 9×6 cm sized dark-brown, stony-hard, irregular, lower abdominal mass of four years duration. The patient had a history of two Cesarean deliveries, 14 and 16 years ago. Suspecting endometriosis, we excised the tumor conservatively rather than extensively to prevent incisional hernia considering the benign nature of the tumor and the low possibility of recurrence because the patient's age was near menopause, along with simultaneous bilateral salpingo-oophorectomy that was performed in this case. On reconstruction, mini-abdominoplasty was adopted to avoid possible wound complications and cosmetic deformities. The patient was satisfied with the cosmetic results, and neither recurrence nor functional problems occurred during the 1-year follow-up period. Plastic surgeons should keep in mind the possibility of cutaneous endometriosis in an abdominal mass of a female of reproductive age with a previous history of pelvic or intra-abdominal surgery. An optimal result from oncological, functional, and cosmetic standpoints can be achieved with conservative excision followed by mini-abdominoplasty of extensive Cesarean scar endometriosis.

An optimal result from oncological, functional, and cosmetic standpoints can beachieved with conservative excision followed by mini-abdominoplasty of extensive Cesareanscar endometriosis.

  7. Hemostatic step-by-step procedure to control presacral bleeding during laparoscopic total mesorectal excision. (United States)

    D'Ambra, Luigi; Berti, Stefano; Bonfante, Pierfrancesco; Bianchi, Claudio; Gianquinto, Daniela; Falco, Emilio


    A new procedure of hemostasis during laparoscopic total mesorectal excision is described. In our surgical department, from January 2004 to December 2007, 128 patients underwent laparoscopic total mesorectal excision. Among them, 47 patients underwent laparoscopic anterior resection after preoperative radiotherapy, 68 patients underwent laparoscopic anterior resection without preoperative radiotherapy, and 13 patients underwent laparoscopic abdominal perineal amputation. In seven laparoscopic rectal surgery cases, we encountered unstoppable presacral bleeding, not amenable by conventional hemostatic solutions. In these cases we applied a simple staging hemostatic procedure. We first performed local compression: tamponing with a small gauze or absorbable fabric hemostat. If bleeding did not stop, we localized an epiploic or omental scrap and excised it by using bipolar forceps and use it as a plug on the tip of a grasping forceps. This plug is then put on the bleeding source and monopolar coagulation is applied by electrified dissecting forceps through the interposed grasping forceps. If bleeding did not stop, we used a little scrap of bovine pericardium graft and tacked it to the bleeding site using endoscopic helicoidal protack. Our experience suggests that this hemostatic step-by-step procedure is a valid option to control persistent presacral hemorrhages.

The areas to be excised from the infrabrow and intrabrow skin were decided upon and the area of hair transplantation was planned in the suprabrow area and the tail of the eyebrow. The skin was removed and the excised intrabrow skin was dissected into single follicular units. Tiny incisions were made with a scalpel, and grafts were inserted using fine forceps.Results: Almost all transplanted eyebrow follicles took successfully, resulting in eyebrows of a desirable shape as planned preoperatively. The reshaped eyebrows had a natural appearance since the transplanted hairs were similar to those of the original eyebrow. The eyelids still looked youthful rather than operated-on. Finally, the evidence of blepharoplasty was hardly visible and patient satisfaction was quite high. The patients felt more ease in opening their eyes and obtained a wider visual field.Conclusion: Our study demonstrated excellent results with hair transplantation from eyebrow to eyebrow, a finding which, to our knowledge, has not been previously reported. Our method can be used for selected patients, especially men, with moderate to severe dermatochalasis, who find a reduction or change in the shape of the eyebrow unacceptable.Keywords: blepharoplasty, dermatochalasis, follicular unit transplantation, eyebrow reconstruction

    Surgical site infection (SSI) following minor surgery contributes to patient morbidity and compromises cosmetic outcomes. The purpose of this study was to determine the incidence of and risk factors for SSI after dermatological surgery in general practice.   A prospective, observational study which assessed infection among 972 patients was conducted in regional north Queensland, Australia. Consecutive patients presenting for minor skin excisions were invited to participate. Wounds were assessed for SSI at the time of removal of sutures. Infection occurred in 85 of the 972 excisions; thus, the overall incidence of infection was 8.7% (95% confidence interval 6.5-11.0). Excisions in the upper (Prisk factors for wound infection. The length of the excision (Prisk factors for infection. Diabetes was not found to be an independent risk factor for infection (P=0.891). Prophylactic antibiotics are probably prescribed excessively or inappropriately for dermatological surgery, and overall we wish to discourage their use. The results of this study may encourage the more judicial use of prophylactic antibiotics by defining high-risk procedures, such as excisions from the extremities, excision of BCC or SCC, and larger excisions, and patients who are at high risk for infection, such as ex-smokers. © 2012 The International Society of Dermatology.

  19. Surgical Treatment of Tattoo Complications. (United States)

    Sepehri, Mitra; Jørgensen, Bo


    With a continuing increase in the number of tattoos performed worldwide, the need to treat tattoo complications is growing. Earlier treatments of chronic inflammatory tattoo reactions were dominated by a medical approach, or with no active intervention. In this chapter, we will address modern surgical approaches applied to situations when medical treatment is inefficient and lasers are not applicable. Dermatome shaving is positioned as first-line treatment of allergic tattoo reactions and also indicated in a number of other tattoo reactions, supplemented with excision in selected cases. The methods allow fundamental treatment with removal of the culprit pigment from the dermis. The different instruments, surgical methods, and treatment schedules are reviewed, and a guide to surgeons is presented. Postoperative treatments and the long-term outcomes are described in detail. An algorithm on specialist treatment and follow-up of tattoo reactions, which can be practiced in other countries, is presented. © 2017 S. Karger AG, Basel.

  20. Analysis of the concordance rates between core needle biopsy and surgical excision in patients with breast cancer Análise das taxas de concordância entre a biópsia com agulha grossa e a excisão cirúrgica em pacientes com câncer de mama

    Directory of Open Access Journals (Sweden)

    Marcos Desidério Ricci


    Full Text Available OBJECTIVE: To evaluate whether immunohistochemical marker studies performed on core needle biopsy (CNB specimens accurately reflect the marker status of the tumor obtained from final surgical specimen. METHODS: This was a retrospective study that used the database of the Division of Mastology of the Hospital das Clínicas, São Paulo, Brazil. Sixty-nine patients submitted to ultrasound-guided CNB diagnosed with breast cancer were retrospectively analyzed. Immunohistochemistry (IHC on core biopsy specimens was compared to that of excisional biopsy regarding estrogen receptor (ER, progesterone receptor (PR, human epidermal gowth factor receptor 2 gene (HER2, p53, and Ki67. The analysis of the concordance between CNB and surgical biopsy was performed using the kappa (k coefficient (95% CI. RESULTS: A perfect concordance between the labeling in the surgical specimens and the preoperative biopsies in p53 (k = 1.0; 95% CI: 0.76-1.0 was identified. There was an almost perfect concordance for ER (k = 0.89; 95% CI: 0.65-1.0 and a substantial concordance for PR (k = 0.70; 95% CI: 0.46-0.93. HER2 (k = 0.61; 95% CI: 0.38-0.84 and Ki-67 (k = 0.74; 95% CI: 0.58-0.98 obtained a substantial concordance this analysis. CONCLUSION: The results of this study indicate that the immunohistochemical analysis of ER, PR, Ki-67, and p53 from core biopsy specimens provided results that accurately reflect the marker status of the tumor. The concordance rate of HER2 was less consistent; although it produced substantial concordance, values were very close to moderate concordance.OBJETIVO: Avaliar se a análise dos marcadores imunoistoquímicos obtidos por meio de espécimes de core biopsy (CB refletem com precisão o perfil dos marcadores tumorais obtidos por biópsia cirúrgica excisional (BCE.

  1. Alar base reduction: the boomerang-shaped excision. (United States)

    Foda, Hossam M T


    A boomerang-shaped alar base excision is described to narrow the nasal base and correct the excessive alar flare. The boomerang excision combined the external alar wedge resection with an internal vestibular floor excision. The internal excision was inclined 30 to 45 degrees laterally to form the inner limb of the boomerang. The study included 46 patients presenting with wide nasal base and excessive alar flaring. All cases were followed for a mean period of 18 months (range, 8 to 36 months). The laterally oriented vestibular floor excision allowed for maximum preservation of the natural curvature of the alar rim where it meets the nostril floor and upon its closure resulted in a considerable medialization of alar lobule, which significantly reduced the amount of alar flare and the amount of external alar excision needed. This external alar excision measured, on average, 3.8 mm (range, 2 to 8 mm), which is significantly less than that needed when a standard vertical internal excision was used ( P < 0.0001). Such conservative external excisions eliminated the risk of obliterating the natural alar-facial crease, which did not occur in any of our cases. No cases of postoperative bleeding, infection, or vestibular stenosis were encountered. Keloid or hypertrophic scar formation was not encountered; however, dermabrasion of the scars was needed in three (6.5%) cases to eliminate apparent suture track marks. The boomerang alar base excision proved to be a safe and effective technique for narrowing the nasal base and elimination of the excessive flaring and resulted in a natural, well-proportioned nasal base with no obvious scarring. © Thieme Medical Publishers.

  2. Surgical consideration of cervical dumbbell tumors. (United States)

    Tomii, Masato; Itoh, Yasunobu; Numazawa, Shinichi; Watanabe, Kazuo


    Nineteen patients with cervical dumbbell tumors treated surgically were analyzed retrospectively. Surgical strategies for dumbbell tumor were discussed from the perspective of safe, less-invasive surgery. Patients included 6 men and 13 women, with a mean age at the time of surgery of 48.3 years (range, 25-70 years). Underlying pathologies included 16 schwannomas, 2 neurofibromas, and 1 double tumor (schwannoma and meningioma). According to Eden's classification, one patient was classified as Type 1, 5 as Type 2, 8 as Type 3, and 5 as Type 4. In 13 cases, tumors were excised through the posterior approach alone, compared to five cases using the anterior approach. One case was excised using combined anterior and posterior approaches. Facetectomy was not performed in 18 cases. In one case, the facet joint on one side had already destroyed and needed instrumentation. Tumors were totally excised in all cases. Postoperatively, the patients did not display any further neurological deficit, with the exception of transient radiculopathy in two patients. Major surgical complications and cerebrospinal fluid leakage were not seen. Tumor recurrence and spinal segmental instability were not found during follow-up period (mean, 41.6 months). Dumbbell tumor surgery requires sufficient debulking of the epidural and paravertebral mass, using intraoperative nerve stimulation and Doppler ultrasonography to detect the vertebral artery. When using a posterior approach, recapping laminoplasty using an ultrasonic bone curette is very useful to remove tumor without sacrificing facet joints.

  3. When pathological and radiological correlation is achieved, excision of fibroadenoma with lobular neoplasia on core biopsy is not warranted. (United States)

    Fives, C; O'Neill, C J; Murphy, R; Corrigan, M A; O'Sullivan, M J; Feeley, L; Bennett, M W; O'Connell, F; Browne, T J


    The diagnosis and management of lobular neoplasia (LN) including lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH) remains controversial. Current management options after a core needle biopsy (CNB) with lobular neoplasia (LN) incorporating both ALH and LCIS include excision biopsy or careful clinical and radiologic follow up. A retrospective analysis of the surgical database at Cork University Hospital was performed to identify all core needle biopsies from January 1st 2010 to 31st December 2013 with a diagnosis of FA who subsequently underwent surgical excision biopsy. All cases with associated LN including ALH and classical LCIS were selected. We excluded cases with coexistent ductal carcinoma in situ (DCIS), invasive carcinoma, LN associated with necrosis, pleomorphic lobular carcinoma in situ (PLCIS) or lesions which would require excision in their own right (papilloma, radial scar, atypical ductal hyperplasia (ADH) or flat epithelial atypia (FEA)). Cases in which the radiologic targeted mass was discordant with a diagnosis of FA were also excluded. 2878 consecutive CNB with a diagnosis of FA were identified. 25 cases had a diagnosis of concomitant ALH or classical LCIS. Our study cohort consisted of 21 women with a mean age 53 years (age range 41-70 years). The core biopsy diagnosis was of LCIS and FA in 16 cases and ALH and FA in 5 cases. On excision biopsy, a FA was confirmed in all 21 cases. In addition to the FA, residual LCIS was present in 14 cases with residual ALH in 2 cases. One of the twenty-one cases (4.8%) was upgraded to invasive ductal carcinoma on excision. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Directory of Open Access Journals (Sweden)

    Tommaso Agostini


    Full Text Available Background: Silicone oil injection can cause several complications including pain, cellulitis, abscesses, skin compromise, migration, embolism and multiorgan failure. Oil-infested tissue excision remains the solely treatment to prevent such complications. Objectives: The authors evaluate tumor-like excision of the oil-infested tissue as a treatment for patients experiencing silicone injections in the lower limbs, to both preserve aesthetic appearance and solve further risk of complication from silicone. Methods: Between January 2004 and January 2011 a total of 12 consecutive, nonrandomized female patients underwent surgical management of siliconoma of the lower limb. The mean age was 41-years, range from 22 to 61 years and all patients didn't referred comorbidities. Eight siliconomas were located on the leg and 4 were on the thigh. The mean area of siliconoma was 35 cm2, range from 25 to 60 cm2. Each patient was evaluated by ultrasonography and EchocolorDoppler of the soft tissue and in order to achieve a “staging” of siliconoma. Results: Healing was uneventful in all cases. Three patients (25% suffering hypertrophic scarring underwent further injection of corticosteroids to improve hypertrophic scars quality. Two patients (16.6% required a further session of structural fat grafting to improve thigh's profile. All patients were satisfied with the cosmetic results and indispositions requiring medical therapy disappeared. Conclusions: Tumor-like excision and immediate reconstruction appears to be a safe and consistent surgical option that preserves aesthetic appearance for patients victims of illegal oil silicone injection of the lower limbs.

  7. Laryngeal schwannoma excised under a microlaryngoscope without tracheotomy: A case report (United States)



    Schwannomas are benign encapsulated tumors arising from Schwann cells in the peripheral nervous system. Between 25 and 45% of schwannomas occur in the head and neck region. Schwannomas of the larynx are extremely rare with an incidence of 0.1–1.5% in all benign laryngeal tumors. Laryngeal schwannomas usually occur in females aged between their 4th and 5th decades. The most successful curative method is surgical resection. When selecting the surgical method, the size and location of the tumor, as well as the requests of the patient, should be considered. The present case report describes a 29-year-old female patient with symptoms of hoarseness and dyspnea on exertion. Through endoscopic biopsy, histopathology revealed a schwannoma. Considering the symptoms, age and preferences of the patient, the method of trans-oral microlaryngoscopic excision without tracheotomy was used to excise the tumor located in the aryepiglottic fold. Results from a short-term follow-up showed the postoperative result to be satisfactory. PMID:24669270

  8. The Evaluation of a Modified Dufourmentel Flap after S-Type Excision for Pilonidal Sinus Disease

    Murat Yildar


    Full Text Available Purpose. The use of an S-type oblique excision with a bilateral gluteus maximus advancement flap has recently been described for the surgical treatment of sacrococcygeal pilonidal sinus (SPS. Its use in wide lesions has been limited due to the need for a full-thickness flap. We describe the use of an S-type oblique incision together with the Dufourmentel flap in wide lesions. Method. Twenty-one patients were treated using a technique including an S-shaped oblique excision of the sinus tract and a broad-pedicled full-thickness flap resembling a Dufourmentel flap to close the defect. Results. Of the 21 patients, 19 (90.5% were male and 2 (9.5% were female. Their mean age was (range 15–36 years. The mean follow-up period was (range 6–23 months. The postoperative complication rate was 4.8% (one patient, and recurrence was seen in one patient (4.8%. The mean return-to-work time was (range 10–18 days. None of the patients reported dissatisfaction with the cosmetic results. Conclusions. This new technique achieved low morbidity and recurrence rates. We anticipate that this will become an important technique in the surgical treatment of SPS if the observed success is confirmed by randomized prospective trials.

  9. Uptake of benzyladenine by excised watermelon cotyledons. (United States)

    Lampugnani, M G; Fantelli, R; Longo, G P; Longo, C P; Rossi, G


    The uptake of 8-[(14)C]N(6)-benzyladenine (BA) was studied in excised watermelon (Citrullus vulgaris Schrad.) cotyledons 24 hours after the start of imbibition. The passive nature of this uptake is suggested by the following evidence: (a) no sign of saturation on increasing external concentration of BA; (b) no decrease in uptake under conditions that inhibit ATP synthesis; (c) no change in amount of radioactivity absorbed when cotyledons are frozen and thawed before the uptake test. About two-thirds of the radioactivity taken up is released after 12 hours of washing. If the washing is performed at 2 C very little radioactivity is released.There seems to be a correlation between the level of radioactivity (i.e. of BA + derivatives) present in the cotyledons and the magnitude of hormonal responses that are observed four days after uptake. This relationship holds regardless of whether a given level of radioactivity has been reached after a short period of uptake or after a long period of uptake followed by washing.

  10. Phonation threshold flow in elongated excised larynges. (United States)

    Jiang, Jack J; Regner, Michael F; Tao, Chao; Pauls, Steven


    This study proposes the use of a new parameter of vocal aerodynamics, phonation threshold flow (PTF). The sensitivities of the PTF and the phonation threshold pressure (PTP) were quantitatively compared to the percent of vocal fold elongation from physiologic length. Ten excised canine larynges were mounted on a bench apparatus capable of controlling vocal fold elongation. Subglottal airflow was gradually increased until the onset of phonation. Elongation of the vocal folds was varied from +0% (physiologic length) to +15%, and the PTF and PTP were measured. The mean PTFs at physiologic vocal fold length ranged from 101 to 217 mL/s. No statistically significant relationship was found to exist between the size of the larynx and the measured PTF values (p = .404). The average percent change of PTF compared to the magnitude of elongation was found to be statistically significant (p < .001). The data indicated that the PTF was proportional to the percent of vocal fold elongation. The PTF was positively correlated with vocal fold elongation and the PTP for small magnitudes of elongation. The results suggest that the PTF may be indicative of the biomechanical properties of the vocal folds, thus providing a possibly valuable tool in the clinical evaluation of laryngeal function.

  11. Development of a long-term ovine model of cutaneous burn and smoke inhalation injury and the effects of early excision and skin autografting (United States)

    Yamamoto, Yusuke; Enkhbaatar, Perenlei; Sakurai, Hiroyuki; Rehberg, Sebastian; Asmussen, Sven; Ito, Hiroshi; Sousse, Linda E.; Cox, Robert A.; Deyo, Donald J.; Traber, Lillian D.; Traber, Maret G.; Herndon, David N.; Traber, Daniel L.


    Smoke inhalation injury frequently increases the risk of pneumonia and mortality in burn patients. The pathophysiology of acute lung injury secondary to burn and smoke inhalation is well studied, but long-term pulmonary function, especially the process of lung tissue healing following burn and smoke inhalation, has not been fully investigated. By contrast, early burn excision has become the standard of care in the management of major burn injury. While many clinical studies and small-animal experiments support the concept of early burn wound excision, and show improved survival and infectious outcomes, we have developed a new chronic ovine model of burn and smoke inhalation injury with early excision and skin grafting that can be used to investigate lung pathophysiology over a period of 3 weeks. Materials and methods Eighteen female sheep were surgically prepared for this study under isoflurane anesthesia. The animals were divided into three groups: an Early Excision group (20% TBSA, third-degree cutaneous burn and 36 breaths of cotton smoke followed by early excision and skin autografting at 24 h after injury, n = 6), a Control group (20% TBSA, third-degree cutaneous burn and 36 breaths of cotton smoke without early excision, n = 6) and a Sham group (no injury, no early excision, n = 6). After induced injury, all sheep were placed on a ventilator and fluid-resuscitated with Lactated Ringers solution (4 mL/% TBS/kg). At 24 h post-injury, early excision was carried out to fascia, and skin grafting with meshed autografts (20/1000 in., 1:4 ratio) was performed under isoflurane anesthesia. At 48 h post-injury, weaning from ventilator was begun if PaO2/FiO2 was above 250 and sheep were monitored for 3 weeks. Results At 96 h post-injury, all animals were weaned from ventilator. There are no significant differences in PaO2/FiO2 between Early Excision and Control groups at any points. All animals were survived for 3 weeks without infectious complication in Early Excision

  12. The Strategy of Excise Taxation of Tobacco Products in Ukraine

    Directory of Open Access Journals (Sweden)

    Pasichnyi Mykola D.


    Full Text Available The article is aimed at disclosing and improving approaches to the development of a strategy of excise tax policy in Ukraine, taking into account the foreign experience of harmonizing tax legislation in this sphere. An analysis of the implementation of the EU directives on the regulation of the minimum excise tax liability for the payment of excise taxes on tobacco products in the countries with transformational economies has been carried out. It has been found that, in cases of excessive tax pressure, the equilibrium of the market is disrupted, its shadow component is growing, and the overall economic efficiency level decreases. It has been determined that for the period of 2007-2016 the availability index for cigarettes in Ukraine decreased 2,3 times, which in some way demotivated their consumption. However, the change in the approach of calculation of ad valorem rate for the excise tax and introduction of the excise tax on the sub-excise goods sold by the retailers led to manipulative actions by the major actors in the market concerning the price of cigarettes, which impacted both the increase in the availability of cigarettes in 2016 and the decline in budget revenues. Regulation of the minimum excise duty is the most effective instrument of fiscal policy to achieve goals in the area of limitation of smoking.

  13. Characteristics of thymine dimer excision from xeroderma pigmentosum chromatin

    International Nuclear Information System (INIS)

    Fujiwara, Y.; Kano, Y.


    We investigated thymine dimer excision from xeroderma pigmentosum (XP) chromatin in the cell-free reconstruction system. The normal-cell extract performed specific dimer excision from native chromatin and DNA isolated from 100 J/m 2 -irradiated cells. Such an excision in vitro was rapid and required high concentrations of extract. The extracts of XP group A, C and G cells were unable to excise from their own native-chromatin, but capable of excising from chromatin deprived of loosely bound nonhistone proteins with 0.35 M NaCl, as were from purified DNA. Thus, group A, C and G cells are most likely to be defective in the specific XP factors facilitating the excising activity under multicomponent regulation at the chromatin level. Further, either of group A, C and G extracts successfully complemented the native chromatin of the alternative groups. Uniquely, the XP group D extract excised dimers from native chromatin in the normal fashion under the condition. These results suggest that XP group A, C, D and G cells examined may not be defective in the dimer specific endonuclease and exonuclease per se. 19 references, 3 figures, 2 tables

  14. [Laparoscopic rectal excision for cancer using total mesorectaol excision (TME). Long term outcome of a series of 179 patients]. (United States)

    Lechaux, D; Redon, Y; Trebuchet, G; Lecalve, J L; Campion, J P; Meunier, B


    The purpose of this study was to evaluate the outcomes and the five-year survival of 179 consecutive patients with rectal carcinoma operated with a laparoscopic procedure between April 1992 and April 2003. Patients with obstructing, bulky cancers were excluded from this study. Tumor stage was defined according to the TNM classification. Preoperative radiation therapy was offered to T(3) N(0) or N(+) patients (45 Gy). The laparoscopic-assisted technique included total mesorectal excision (TME), primary high vascular ligation, centrifugal dissection of the mesentery, and "no touch" technique. All the N+ patients received adjuvant chemotherapy. The outcomes were defined as five-years recurrence (local recurrence and distant metastasis) and the diseases-free survival. The survival rates were calculated with the Kaplan-Meier test. There were 108 males and 71 females, median age was 67 (range 39-88). There were 61 upper rectum localizations (34%), 68 middle rectum (38%) and 50 low rectum (28%). Twenty-nine patients required open conversion (16%). Surgical operative morbidity was 24% and medical morbidity was 4%. There were 60 stage I (40%), 25 stage II (16%), 49 stage III (32%), and 16 stage IV (10%). Ninety patients (71%) are alive and disease free, ten (5%) are alive with disease recurrence, and 37 patients (20%) are deceased. Only one case of trocar site implantation occurred after curative resection during an average follow up of 76 months. Five-year observed survival rate were 85% for stage I, 70% for stage II, and 63% for stage III. In our experience laparoscopic rectal resection could be done safely. The oncologic outcome was similar to that of open surgery. Further randomized trials will be necessary to confirm the value of this technique.

    We report on 30 symptomatic cases of carpal boss which were treated surgically. The condition represents a highly localized degenerative arthritis at the base of the middle metacarpal, and is seen primarily in relatively young patients. Symptomatic relief was obtained by excision of degenerated tissue in all these patients.

  17. Combination of Surgical Drainage and Renal Artery Embolization: An Alternative Treatment for Xanthogranulomatous Pyelonephritis

    Energy Technology Data Exchange (ETDEWEB)

    Upasani, Anand, E-mail: [Great Ormond Street Hospital, Department of Paediatric Urology (United Kingdom); Barnacle, Alex, E-mail:; Roebuck, Derek, E-mail:; Cherian, Abraham, E-mail: [Great Ormond Street Hospital (United Kingdom)


    Conventionally, xanthogranulomatous pyelonephritis is treated with antibiotics and drainage of abscess followed by nephrectomy for definitive treatment. Surgical excision of the affected kidney carries risk of significant complications. An alternative treatment modality is described in the form of embolization of the renal artery to devascularise the renal parenchyma and ablate the renal tissue, thus avoiding a major surgical procedure and the significant risks involved.

  19. Trapezium excision and suture suspensionplasty (TESS) for the treatment of thumb carpometacarpal arthritis. (United States)

    Putnam, Matthew D; Meyer, Nicholas J; Baker, Daniel; Brehmer, Jess; Carlson, Brent D


    Basilar thumb arthritis, or first carpometacarpal arthritis, is a common condition affecting older women and some men. It is estimated that as many as one third of postmenopausal woman are affected. Surgical treatment of this condition includes options ranging from arthrodesis to prosthetic arthroplasty. Intermediate options include complete or partial trapezial excision with or without interposition of a cushioning/stabilizing material (auto source, allo source, synthetic source). A multitude of methods appear to offer similar end results, although some methods definitely involve more surgical work and perhaps greater patient risk. Through retrospective evaluation of a cohort of patients who underwent suture suspensionplasty, we determined the postoperative effect on strength, motion, patient satisfaction, complications, and radiographic maintenance of the scaphoid-metacarpal distance. This review shows the method to be clinically effective and, by comparison with a more traditional ligament reconstruction trapezial interposition arthroplasty, the method does not require use of autograft or allograft tendon and has fewer surgical steps. Forty-four patients were included in this retrospective study. The results showed that 91% of patients were satisfied with the procedure. Pinch and grip strength remained the same preoperatively and postoperatively. A Disabilities of the Arm, Shoulder, and Hand patient-reported outcome instrument (DASH) scores averaged 30 at final follow-up. Three patients developed a late complication requiring further surgical intervention. In summary, this technique appears to be technically reproducible, requires no additional tendon material, and achieves objectively and subjectively similar results to other reported procedures used to manage first CMC Arthritis.

  20. Robot-Assisted Excision of a Pararectal Gastrointestinal Stromal Tumor in a Patient with Previous Ileal Neobladder

    Directory of Open Access Journals (Sweden)

    A. Ploumidis


    Full Text Available Gastrointestinal stromal tumors (GISTs are the most frequent mesenchymal tumors of the gastrointestinal tract with surgical resection remaining the cornerstone of therapy. Pararectal lesions are considered to be technically difficult and pose in some cases a challenge. We report, to the best of our knowledge, the first robotic-assisted pararectal GIST excision. A 43-year-old man was referred to our center with pararectal GIST recurrence, despite treatment with targeted therapy. Eleven years ago, he underwent extensive abdominal surgery including cystoprostatectomy with ileal neobladder diversion due to GIST resection in the rectoprostatic space. Robot-assisted surgical resection was successfully performed without the need for temporary colostomy. The postoperative course of the patient was uneventful, and the pathology report confirmed a GIST recurrence with negative surgical margins and pelvic lymph nodes free of any tumor. Robotic-assisted pelvic surgery can be extended to incorporate excision of pararectal GISTs, as a safe, less invasive surgical alternative with promising oncological results and minimal injury to adjacent structures.

  1. Development of excise on automotive fuels in the neighbouring countries

    International Nuclear Information System (INIS)

    Bleijenberg, A.N.; Janse, P.


    The political options for the Netherlands to implement the pricing policy for road traffic by means of an increase of excise, as formulated in the Second Transport Structure Plan (SVV-2), are limited by the excise level in neighbouring countries. Therefore, a study on the title subject has been carried out. First, an overview is given of the historical development of sales prices since 1980 for Belgium, Germany, Luxembourg and France with special attention for the large price differences. Next, insight into the effects of a price difference at the borders is given. Subsequently the development in the policy of the European Union with regard to harmonization of excise tariffs is discussed. Environmental organizations in Belgium and Luxembourg were contacted to learn about the expected development of excises in those countries. 5 figs., 6 tabs., 4 appendices, 10 refs

  5. Genomic island excisions in Bordetella petrii

    Directory of Open Access Journals (Sweden)

    Levillain Erwan


    Full Text Available Abstract Background Among the members of the genus Bordetella B. petrii is unique, since it is the only species isolated from the environment, while the pathogenic Bordetellae are obligately associated with host organisms. Another feature distinguishing B. petrii from the other sequenced Bordetellae is the presence of a large number of mobile genetic elements including several large genomic regions with typical characteristics of genomic islands collectively known as integrative and conjugative elements (ICEs. These elements mainly encode accessory metabolic factors enabling this bacterium to grow on a large repertoire of aromatic compounds. Results During in vitro culture of Bordetella petrii colony variants appear frequently. We show that this variability can be attributed to the presence of a large number of metastable mobile genetic elements on its chromosome. In fact, the genome sequence of B. petrii revealed the presence of at least seven large genomic islands mostly encoding accessory metabolic functions involved in the degradation of aromatic compounds and detoxification of heavy metals. Four of these islands (termed GI1 to GI3 and GI6 are highly related to ICEclc of Pseudomonas knackmussii sp. strain B13. Here we present first data about the molecular characterization of these islands. We defined the exact borders of each island and we show that during standard culture of the bacteria these islands get excised from the chromosome. For all but one of these islands (GI5 we could detect circular intermediates. For the clc-like elements GI1 to GI3 of B. petrii we provide evidence that tandem insertion of these islands which all encode highly related integrases and attachment sites may also lead to incorporation of genomic DNA which originally was not part of the island and to the formation of huge composite islands. By integration of a tetracycline resistance cassette into GI3 we found this island to be rather unstable and to be lost from

  6. Surgical treatment of thymoma. (United States)

    Miller, Quintessa; Moulton, Michael J; Pratt, Jerry


    A case report is presented of a 66-year-old white woman with a 3-month history of atypical chest pain and shortness of breath. A lateral chest radiograph demonstrated an anterior mediastinal density. A subsequent computed tomography (CT) scan revealed a mass in the right anterolateral mediastinum. Fine-needle aspiration (FNA) revealed tumor cells positive for cytokeratin and negative for leukocyte common antigen. The differential diagnosis at that time included thymoma versus thymic carcinoid. She underwent a median sternotomy with complete thymectomy. The pathology revealed a large thymoma with microinvasion into the surrounding adipose tissue. She had an uneventful postoperative course and later underwent adjuvant radiation therapy. Surgical treatment of thymoma is discussed, with emphasis on diagnosis and treatment. Although some patients may present with symptoms caused by involvement of surrounding structures, most thymomas are discovered incidentally on chest radiograph. Various diagnostic procedures can aid the surgeon in ruling out other neoplasms, such as lymphoma or germ cell tumors. Prognosis is not based on histology, but on the tumor's gross characteristics at operation. Benign tumors are noninvasive and encapsulated. All patients with potentially resectable lesions should undergo en-bloc excision. Radiation or chemotherapy should be instituted in more advanced tumors.

  8. Length of Distal Resection Margin after Partial Mesorectal Excision for Upper Rectal Cancer Estimated by Magnetic Resonance Imaging

    DEFF Research Database (Denmark)

    Bondeven, Peter; Hagemann-Madsen, Rikke Hjarnø; Bro, Lise

    BACKGROUND: Rectal cancer requires surgery for cure. Partial mesorectal excision (PME) is suggested for tumours in the upper rectum and implies transection of the mesorectum perpendicular to the bowel a minimum of 5 cm below the tumour. Reports have shown distal mesorectal tumour spread of up to 5...... cm from the primary tumour; therefore, guidelines for cancer of the upper rectum recommend PME with a distal resection margin (DRM) of at least 5 cm or total mesorectal excision (TME). PME exerts a hazard of removing less than 5 cm - leaving microscopic tumour cells that have spread in the mesorectum....... Studies at our department have shown inadequate DRM in 75 % of the patients estimated by post-operative MRI of the pelvis and by measurements of the histopathological specimen. Correspondingly, a higher rate of local recurrence in patients surgically treated with PME for rectal cancer - compared to TME...

  9. Artificial Dermis Graft on the Mandible Lacking Periosteum After Excision of an Ossifying Fibroma: A Case Report

    Directory of Open Access Journals (Sweden)

    Chun-Ming Chen


    Full Text Available Collagen-based grafts have often been used as artificial tissue substitutes for the repair of tissue and organ defects. It is common surgical knowledge that autogenous or artificial skin grafts take well on the intact periosteum of bone. However, many experienced surgeons indicate that auto-genous or artificial skin grafts subsist poorly on the bone surface without periosteum. Therefore, primary closure is usually recommended in the wound healing of exposed bone. Vestibuloplasty might be needed to create enough depth of vestibule in the future. In this case report, we describe a peripheral ossifying fibroma surgically excised leaving a bony defect, which was covered by a piece of artificial dermis. Satisfactory result of the repaired surgical defect showed no need of vestibuloplasty after 6 years of follow-up.

  12. Providers issue brief: tobacco: excise taxes: year end report-2003. (United States)

    McKinley, Andrew


    All 50 states, the District of Columbia, and the federal government impose excise taxes on cigarettes and have done so for many years. State tobacco taxes range from a high of $2.05 per pack of cigarettes in New Jersey to a low of $0.03 in Virginia per pack. The federal government levies an excise tax that increased by $0.05 on Jan. 1, 2002, to $0.39 per package. Cigarette taxes are directed at the consumer, while taxes on other tobacco products focus on the wholesaler. In the 2002 legislative sessions, 33 states proposed increases in cigarette excise taxes as a means of addressing budget shortfalls; 20 states enacted increases. Increasing tobacco excise taxes may decrease tobacco usage and increase state revenue. Increasing cigarette taxes is a means of generating revenue that generally is supported by public opinion. For instance, a 2003 poll in Ohio found that 63 percent of the public favored increasing cigarette excise taxes as long as the revenue is used for health care purposes. Cigarette excise taxes was again an area of substantial legislative interest and activity due to continued state budget deficits. A February 2003 NCSL study of state budget shortfalls indicated that the current cumulative budget gap is approximately $25.7 billion for fiscal year (FY) 2003. State revenues were sluggish and generally most failed to meet budgeted levels. At least 30 states noted that general fund collections were below budgeted estimates, and 12 states reported that collections failed to meet revised levels. Although the additional tax revenue generated by raising excise taxes may not eliminate state budget shortfalls, the revenue may provide funds for specific state programs.This issue brief provides an overview of the policy issue, a brief history of tobacco taxation in the 50 states and the District of Columbia, an overview of legislative activity in 2003, and a state-by-state map of state tobacco taxes.

  13. Transvaginal Excision of an Eroded Sacrocolpopexy Mesh by Using Single-Incision Laparoscopic Surgery Equipment. (United States)

    Mohr, Stefan; Siegenthaler, Franziska; Imboden, Sara; Kuhn, Annette; Mueller, Michael D

    To show a new technique of using single-incision laparoscopic surgery (SILS) equipment in vaginal surgery to create a "pneumovagina." Explanatory video demonstrating the technique and intraoperative findings. University hospital. The 68-year-old patient was referred with a vaginal mesh erosion that resulted in abscess formation at the vaginal apex. The patient was symptomatic with an increasingly foul-smelling vaginal discharge for about 1 year. She had a laparoscopic sacrocolpopexy in a remote hospital 22 months before the current operation and had a total abdominal hysterectomy 15 years ago. The, patient's history was uneventful without dyspareunia, incontinence or voiding difficulties, and she was otherwise content with the sacrocolpopexy result. The local institutional review board granted exemption for this publication. Frequently, pelvic organ prolapse can only be effectively treated if the surgical procedure comprises support of the central compartment. Laparoscopic sacrocolpopexy shows superior outcomes for this indication, with success rates of up to 96%. However, a rare side effect of laparoscopic sacrocolpopexy is mesh erosion, occurring in up to 2.4% [1]. These erosions are usually treated laparoscopically [2]. In this video we show an alternative route for excision of a symptomatic exposed mesh by using a transvaginal approach: The SILS trocar is used vaginally for abscess irrigation and mesh excision with minimally invasive instruments. For treatment of the abscess and removal of the exposed mesh, the SILS trocar was placed vaginally, and laparoscopic instruments were used. The abscess was incised, cleansed and irrigated, debrided, and the mesh excised. Because no mesh material was exposed after excision, the vagina was not closed to avoid creating a cavity with the risk of promoting reabscess formation, and secondary wound healing was anticipated. Laparoscopy was used to confirm that no intra-abdominal lesion coexisted or occurred. There were

  14. Intermediate and Long-term Outcomes of Giant Fibroadenoma Excision in Adolescent and Young Adult Patients. (United States)

    Cerrato, Felecia E; Pruthi, Sandhya; Boughey, Judy C; Simmons, Patricia S; Salje, Barbara; Nuzzi, Laura C; Lemaine, Valerie; Labow, Brian I


    Giant fibroadenomas (5 cm or greater) are benign breast masses that often present in adolescence and require surgical excision. Long-term outcomes, recurrence rates, and the need for additional reconstructive surgery in this population are unknown. Patients aged 11-25 years whose pathology reports indicated the presence of a giant fibroadenoma were eligible for this study. Medical records were reviewed for presentation, treatment, and outcomes. A subset of patients completed an investigator-designed long-term outcome survey to measure additional outcomes and the desire or need for subsequent reconstructive surgery. Forty-six patients with at least one giant fibroadenoma (mean size 7.4 ± 2.8 cm) were identified. Most patients underwent excision with a periaroeolar incision (n = 31), and an enucleation technique (n = 41), and four patients underwent immediate breast reconstruction. Thirty-three patients had complete medical records with a mean follow-up time of 2.2 ± 4.1 years and no complaints of asymmetry, additional breast deformities, or reconstructive surgery procedures documented. In addition, nine patients completed the investigator-designed survey with a mean follow-up time of 10.1 ± 8.7 years (range 1.5-27.0). Three of these patients reported postoperative breast asymmetry and the desire to pursue reconstructive surgery. Aesthetic outcomes of giant fibroadenoma excision may be satisfactory for many patients without immediate reconstruction, but for others, the need for reconstructive surgery may arise during development. Providers should address this potential need prior to discussing treatment options and during postoperative follow-up. Caution should be exercised before recommending immediate reconstruction. © 2015 Wiley Periodicals, Inc.

  15. Surgical Treatment in Uveal Tumors

    Directory of Open Access Journals (Sweden)

    Kaan Gündüz


    Full Text Available Surgical treatment in uveal tumors can be done via iridectomy, partial lamellar sclerouvectomy (PLSU and endoresection. Iridectomy is done in iris tumors without angle and ciliary body involvement. PLSU is performed in tumors with ciliary body and choroidal involvement. For this operation, a partial thickness scleral flap is dissected, the intraocular tumor is excised, and the flap is sutured back in position. PLSU surgery is done in iridociliary and ciliary body tumors with less than 3 clock hours of iris and ciliary body involvement and in choroidal tumors with a base diameter less than 15 mm. However, it can be employed in any size tumor for biopsy purposes. Potential complications of PLSU surgery include vitreous hemorrhage, cataract, retinal detachment, and endophthalmitis. Endoresection is a technique whereby the intraocular tumor is excised using vitrectomy techniques. The rationale for performing endoresection is based on the fact that irradiated uveal melanomas may be associated with exudation and neovascular glaucoma and removing the dead tumor tissue may contribute to better visual outcome. There are some centers where endoresection is done without prior radiotherapy. Allegedly, avoidance of radiation retinopathy and papillopathy are the main advantages of using endoresection without prior radiotherapy. (Turk J Ophthalmol 2014; 44: Supplement 29-34

  16. Surgical treatment of a canine intranasal meningoencephalocele. (United States)

    Martlé, Valentine A; Caemaert, Jacques; Tshamala, Mulenda; Van Soens, Iris; Bhatti, Sofie F M; Gielen, Ingrid; Piron, Koen; Chiers, Koen; Tiemessen, Ilse; Van Ham, Luc M


    To report the clinical signs, diagnosis, and surgical treatment of an intranasal meningoencephalocele in a dog. Case report. Female Border collie, 5 months old. A right intranasal meningoencephalocele was identified by computed tomography and magnetic resonance imaging. The lesion was approached by a modified transfrontal craniotomy. Surgical closure of the defect at the level of the cribriform plate and removal of extruded brain tissue resulted in regression of lacrimation and coincided with absence of seizuring. Treatment with phenobarbital was gradually reduced and stopped at 7 months after surgery. At 28 months the dog remained free of seizures. Meningoencephalocele, although rare, can cause seizures in dogs and can be treated surgically. A transfrontal craniotomy with excision of the meningoencephalocele and closure of the defect can be an effective treatment for an intranasal meningoencephalocele in dogs.

  17. Quantification of surgical blood loss. (United States)

    Lee, Marcel H; Ingvertsen, Britt T; Kirpensteijn, Jolle; Jensen, Asger L; Kristensen, Annemarie T


    To compare gravimetric and colorimetric methods of quantifying surgical blood loss, and to determine if there is a correlation between preoperative hemostatic tests (buccal mucosa bleeding time [BMBT] and intraoperative blood loss). Prospective clinical study. Dogs (n=15) admitted for cutaneous tumor excision, orthopedic procedure, or exploratory laparotomy. Intraoperative blood loss was quantified by measuring irrigation fluid and weighing surgical sponges used for blood and fluid collection during surgery. Results of gravimetric measurements were then correlated to blood loss quantified using spectrophotometric analysis of hemoglobin (Hb) content. Hemostatic variables including BMBT were measured before surgery and compared with the calculated amount of blood loss. Blood loss quantified by gravimetric measurement showed a significant correlation with colorimetric determination of Hb content in surgical sponges and collected irrigation fluid (r=0.93, P<.0001). BMBT correlated weakly but significantly with intraoperative blood loss (r=0.56, P<.05). Quantifying intraoperative blood loss using spectrophotometric Hb analysis accurately assessed the amount of blood loss; however, it is a time-consuming procedure, primarily applicable as a research tool. Gravimetric evaluation of intraoperative blood loss was found to be an accurate method, which can be recommended for use in a clinical setting. Estimation of blood loss using a gravimetric method is accurate and applicable in the clinical setting and provides surgeons with a simple and objective tool to evaluate intraoperative blood loss.

  18. Arthroscopic excision of an ununited ossicle due to Osgood-Schlatter disease. (United States)

    Beyzadeoglu, Tahsin; Inan, Muharrem; Bekler, Halil; Altintas, Faik


    Surgical excision of the ossicles has been suggested for unresolved sequelae of Osgood-Schlatter disease in adults resistant to conservative measures. A 24-year-old, male semiprofessional soccer player had anterior knee pain during sports activity and climbing stairs that had been treated conservatively for 2 years. On physical examination, there was a permanent tibial tubercle with pain. On radiographic examination, an ununited ossicle was seen beneath the patellar tendon. Arthroscopy was performed through the standard low anterolateral and anteromedial portals close to the patellar tendon. Soft tissue at the retropatellar surface and the inflamed infrapatellar fat pad beneath the patellar tendon were debrided with a motorized shaver. Localization of the ununited ossicle was performed by use of an image intensifier. The ossicle was separated from the surrounding soft tissue with a motorized shaver and removed by use of a grasper. After excision of the ossicle, the inflamed surface of the retropatellar tendon was also debrided. The contouring of the irregular surface of the tibial tubercle was performed by use of a motorized bur. After 6 weeks, the patient returned to sports activities without any restrictions. This study showed that all of the described procedures might be done arthroscopically and sports activity may be allowed earlier.

  19. A new dry eye mouse model produced by exorbital and intraorbital lacrimal gland excision. (United States)

    Shinomiya, Katsuhiko; Ueta, Mayumi; Kinoshita, Shigeru


    Chronic dry eye is an increasingly prevalent condition worldwide, with resulting loss of visual function and quality of life. Relevant, repeatable, and stable animal models of dry eye are still needed. We have developed an improved surgical mouse model for dry eye based on severe aqueous fluid deficiency, by excising both the exorbital and intraorbital lacrimal glands (ELG and ILG, respectively) of mice. After ELG plus ILG excision, dry eye symptoms were evaluated using fluorescein infiltration observation, tear production measurement, and histological evaluation of ocular surface. Tear production in the model mice was significantly decreased compared with the controls. The corneal fluorescein infiltration score of the model mice was also significantly increased compared with the controls. Histological examination revealed significant severe inflammatory changes in the cornea, conjunctiva or meibomian glands of the model mice after surgery. In the observation of LysM-eGFP (+/-) mice tissues, postsurgical infiltration of green fluorescent neutrophils was observed in the ocular surface tissues. We theorize that the inflammatory changes on the ocular surface of this model were induced secondarily by persistent severe tear reduction. The mouse model will be useful for investigations of both pathophysiology as well as new therapies for tear-volume-reduction type dry eye.

  20. Total Mesorectal Excision, an erroneous anatomical term for the gold standard in rectal cancer treatment. (United States)

    Rodríguez-Luna, María Rita; Guarneros-Zárate, Joaquín E; Tueme-Izaguirre, Jorge


    In 1986 Professor R J Heald published in The Lancet his new technique which he called Total Mesorectal Excision; today this is the gold standard for the surgical management of rectal cancer. In Total Mesorectal Excision (TME), the mesorectum is the term used to describe all the peri-rectal connective tissue including the posterior sheath of the endopelvic fascia containing the peri-rectal neurovascular structures. However, the mesenterium is a defined structure composed of a double layer of peritoneum which does not include the endopelvic fascia and the lateral rectal stalks, so these should not be included in the term 'mesorectum'. In our globalized medical culture it is important to use anatomic terms approved by the International Federation of Associations of Anatomists, as contained in the Terminologia Anatomica produced by the Federative International Programme for Anatomical Terminology (FIPAT). The term mesorectum is not listed in the Terminologia Anatomica. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.

  1. Uracil excision repair in Mycobacterium tuberculosis cell-free extracts. (United States)

    Kumar, Pradeep; Bharti, Sanjay Kumar; Varshney, Umesh


    Uracil excision repair is ubiquitous in all domains of life and initiated by uracil DNA glycosylases (UDGs) which excise the promutagenic base, uracil, from DNA to leave behind an abasic site (AP-site). Repair of the resulting AP-sites requires an AP-endonuclease, a DNA polymerase, and a DNA ligase whose combined activities result in either short-patch or long-patch repair. Mycobacterium tuberculosis, the causative agent of tuberculosis, has an increased risk of accumulating uracils because of its G + C-rich genome, and its niche inside host macrophages where it is exposed to reactive nitrogen and oxygen species, two major causes of cytosine deamination (to uracil) in DNA. In vitro assays to study DNA repair in this important human pathogen are limited. To study uracil excision repair in mycobacteria, we have established assay conditions using cell-free extracts of M. tuberculosis and M. smegmatis (a fast-growing mycobacterium) and oligomer or plasmid DNA substrates. We show that in mycobacteria, uracil excision repair is completed primarily via long-patch repair. In addition, we show that M. tuberculosis UdgB, a newly characterized family 5 UDG, substitutes for the highly conserved family 1 UDG, Ung, thereby suggesting that UdgB might function as backup enzyme for uracil excision repair in mycobacteria.

  2. Quantification of the Learning Curve for Arthroscopic Os Trigonum Excision. (United States)

    Yamakado, Kotaro


    The purpose of the present study was to quantify the learning curve for arthroscopic os trigonum excision using the log-linear model. Twenty-three consecutive feet underwent arthroscopic os trigonum excision and release of the flexor hallucis longus. The required time from the beginning of shaving of the soft tissue until completion of os trigonum excision and release of the flexor hallucis longus (van Dijk time) was recorded. Regression analysis was applied to predict the required time on the basis of the cumulative case volume after logarithmic transformation of both statistics. The mean required time was 35.2 (range 9 to 90) minutes. After logarithmic transformation, a significant linear correlation was observed between the required time and the cumulative case volume (p = .0043). The best-fit linear equation was calculated as log (y, estimated required time)  = -0.41 log (x, case volume) + 1.86, resulting in an estimated learning rate of 75.3% (= 2 -0.41 ). The results showed an overall time reduction in arthroscopic os trigonum excision in support of a learning curve effect with an ~75% learning rate, indicating that the required time for arthroscopic os trigonum excision can decrease by ≤25% when the cumulative volume of cases has doubled.

  3. Re-excision rates of invasive ductal carcinoma with lobular features compared with invasive ductal carcinomas and invasive lobular carcinomas of the breast. (United States)

    Arps, David P; Jorns, Julie M; Zhao, Lili; Bensenhaver, Jessica; Kleer, Celina G; Pang, Judy C


    Invasive ductal carcinoma (IDC) with lobular features (IDC-L) is not recognized as a subtype of breast cancer. We previously showed that IDC-L may be a variant of IDC with clinicopathological characteristics more similar to invasive lobular carcinoma (ILC). We sought to determine the re-excision rates of IDC-L compared with ILC and IDC, and the feasibility of diagnosing IDC-L on core biopsies. Surgical procedure, multiple tumor foci, tumor size, and residual invasive carcinoma on re-excision were recorded for IDC-L (n = 178), IDC (n = 636), and ILC (n = 251). Re-excision rates were calculated by excluding mastectomy as first procedure cases and including only re-excisions for invasive carcinoma. Slides of correlating core biopsies for IDC-L cases initially diagnosed as IDC were re-reviewed. For T2 tumors (2.1-5.0 cm), re-excision rates for IDC-L (76 %) and ILC (88 %) were higher than that for IDC (42 %) (p = 0.003). Multiple tumor foci were more common in IDC-L (31 %) and ILC (26 %) than IDC (7 %) (p < 0.0001), which was a significant factor in higher re-excision rates when compared with a single tumor focus (p < 0.001). Ninety-two of 149 patients (62 %) with IDC-L were diagnosed on core biopsies. Of the 44 patients initially diagnosed as IDC, 30 were re-reviewed, of which 24 (80 %) were re-classified as IDC-L. Similar to ILC, re-excision rates for IDC-L are higher than IDC for larger tumors. Patients may need to be counseled about the higher likelihood of additional procedures to achieve negative margins. This underscores the importance of distinguishing IDC-L from IDC on core biopsies.

  5. Shaved margin histopathology and imprint cytology for assessment of excision in canine mast cell tumors and soft tissue sarcomas. (United States)

    Milovancev, Milan; Townsend, Kaitlin L; Gorman, Elena; Bracha, Shay; Curran, Katie; Russell, Duncan S


    To determine the feasibility and agreement of margin assessment by imprint cytology, shaved margin histopathology, and radial section histopathology in canine cutaneous and subcutaneous mast cell tumors (MCT) and soft tissue sarcomas (STS). Prospective clinical study. Three hundred and forty margins from 72 excised tumors (52 MCT and 20 STS) in 54 client-owned dogs. Imprint cytology samples were acquired by pressing glass slides to the cut surgical margin of the freshly excised surgical specimen. Shaved margin samples were obtained from the patient wound bed using a scalpel immediately prior to closure. Radial section histopathology was performed as part of routine histopathologic processing. All margins were assessed as either positive or negative for presence of tumor cells at the surgical margin. Agreement among methods was calculated using Fleiss Kappa coefficients and an association of method, margin direction, and tumor type with positive margin status was evaluated using a general linear mixed model. Positive margin detection rates differed for MCT (imprint cytology 21%, radial section histopathology 9%, and shaved margin histopathology 3%; P histopathology are feasible, but their results are frequently disparate from routine radial section histopathology. Future studies are needed to evaluate the correlation of each method with local recurrence rates. © 2017 The American College of Veterinary Surgeons.

    P. Rosatelli


    Full Text Available A thirteen-year-old female spayed with a history of hydronephrosis was presented for a routine abdominal ultrasonographic exam. The imaging exam showed a mass involving the pancreas and a large mass affecting the spleen. Exploratory laparotomy evidenced a mass in the pancreas and another involving one-third of the spleen. The patient had partial pancreatectomy and splenectomy. The histopathology report came back with a diagnosis of pancreatic carcinoma. Adjuvant chemotherapy was declined. The cat is still free of gross tumor recurrence and metastatic disease after twenty-six months. Early diagnosed and aggressively treated feline pancreatic carcinoma might yield a favorable prognosis.

  7. Probe-guided surgery: metastases of a papillary thyroid carcinoma. Surgical Excision

    Kowadlo, A.R.; Zund, S.; Perez Irigoyen, C.


    A male patient with papillary thyroid cancer -follicular variety- is chosen to be presented. After thyroidectomy, lymphadenectomy and therapeutic dose of radioiodine treatments, cancer relapse was observed. After thyrotrophin suppressive therapy with l-thyroxine, a high serum thyroglobulin concentration was observed. The Ultrasonography (US) and Magnetic Resonance (MR) images showed visible node structures in the neck. This node structures were probably going to concentrate I-131 as seen in the fi rst whole body scan after therapeutic dose. Therefore a radio-guided surgery was planned as the best choice. (Institute Gustave Roussy protocol). A therapeutic dose of radioiodine (I-131) was given and up to the 4th day a whole body scan was performed. In the 5th day a gamma- probe-guided surgery was performed as well, and localized metastatic foci in the pretracheal region and under right recurrent laryngeal nerve. No other foci were identified ed with the probe at surgery. Forty eight hours after surgery a new whole-body scan was made again. The procedure was successful. The metastatic lesions were completely dissected. The last whole body scan showed that radioiodine concentration had disappeared at all. Forty fi ve days and three months after surgery under levothyroxine treatment, the serum thyroglobulin level concentration decrease to very low values. (authors) [es

    A scar in the upper extremities sometimes leads to onset of keloid, whose treatment is difficult and many treatment methods have been tried. Recently our hospital has performed electron beam radiation for treatment of keloid. In this report, we describe our examination on patients with keloid in the upper extremities who visited our hospital and underwent electron beam irradiation in these past 7 years. The patients were 9 males and 15 females, age between 9 and 84 (average age 26.6 years). Treatments included the following: Total ablation of keloid plus electron beam radiation, electron beam radiation alone, localized administration of triamcinolone. Treatment evaluation and presence or absence of pigmentation was examined. Electron beam radiation was performed with a total of 25 Gy for consecutive 5 days by 5 Gy electron beam since 1 week after keloid ablation with sufficient informed consent. Onset site of 24 patients with keloid in the upper extremities was the shoulder in 12 patients, the upper arm in 11, and the elbow in one patient. Development cause was BCG inoculation in 8 patients, wound associated with surgery in 6, unknown cause in 6, and others in 4 patients. The number of patients who were followed-up after treatment was 16 for each examination respectively, and mean followed-up period was 2 years and 10 months. Postoperative evaluation for ablation plus electron beam was good in 1 patient and fair in 6, that for electron beam radiation alone was good in 1, fair in 2, and unknown in 2, and that for triamcinolone was fair in 2, poor in 4, and unknown in 1 patient. Postoperative pigmentation was observed in all the patients immediately after radiation, and at the time of final follow-up, in 6 (33%) out of 9 patients confirmed. Ablation plus electron beam irradiation for keloid in the upper extremities was effective. However, this treatment cannot avoid a possibility of cancerogenesis. Thus, sufficient explanation and consent may be essential after full consideration of its application. A number of iatrogenic keloid cases such as BCG are observed. Thus, change in inoculation site may be necessary. (author)

  9. Elbow joint kinematics after excision of the radial head

    DEFF Research Database (Denmark)

    Jensen, Steen Lund; Olsen, Bo Sanderhoff; Søjbjerg, Jens Ole


    The contribution of the radial head to elbow joint kinematics was studied in 7 osteoligamentous elbow preparations. During unloaded flexion and extension, radial head excision induced a maximum varus displacement of 1.6 degrees with 20 degrees of joint flexion and a maximum external rotation of 3.......2 degrees at 110 degrees of flexion. With application of a 0.75-Nm load, radial head excision induced a maximum laxity of 3.3 degrees at 20 degrees of flexion in forced varus and a maximum laxity of 8.9 degrees at 10 degrees of flexion in forced external rotation. No laxity was observed in forced valgus...... or internal rotation. The results were independent of the rotation of the forearm. This study indicates that the radial head acts as stabilizer to the elbow joint in forced varus and in forced external rotation. The results suggest that fractures of the radial head cannot be treated by simple excision without...

  10. Total excision of intramedullary epidermoid cyst in one case

    Directory of Open Access Journals (Sweden)

    PU Ke


    Full Text Available Clinical experience of total excision in a 14-year-old female with intramedullary epidermoid cyst was reported. The patient with L3-4 intramedullary epidermoid cyst underwent total excision through posterior median approach under microscopy. The patient was admitted for progressive strephexopodia and urinary and fecal incontinence. Preoperative imaging examination showed scoliosis, incontionous L4-S1 and abnormal signal of L3-4. Total excision and spinal remodeling were performed under intraoperative neurophysiological monitoning. Epidermoid cyst and its membrane were totally removed without aseptic meningitis after surgery, and the neurologic symptoms of the patient were gradually improved. Completely removing the membrane of epidermoid cyst is the key point to prevent recurrence and aseptic meningitis postoperatively. Dissection should be strictly in accordance with the boundaries of the membrane and the spinal cord, in order to avoid spinal cord injury.

  11. Development of a positron probe for localization and excision of brain tumours during surgery

    The survival outcome of patients suffering from gliomas is directly linked to the complete surgical resection of the tumour. To help the surgeons to delineate precisely the boundaries of the tumour, we developed an intraoperative positron probe with background noise rejection capability. The probe was designed to be directly coupled to the excision tool such that detection and removal of the radiolabelled tumours could be simultaneous. The device consists of two exchangeable detection heads composed of clear and plastic scintillating fibres. Each head is coupled to an optic fibre bundle that exports the scintillating light to a photodetection and processing electronic module placed outside the operative wound. The background rejection method is based on a real-time subtraction technique. The measured probe sensitivity for {sup 18}F was 1.1 cps kBq{sup -1} ml{sup -1} for the small head and 3.4 cps kBq{sup -1} ml{sup -1} for the large head. The mean spatial resolution was 1.6 mm FWHM on the detector surface. The {gamma}-ray rejection efficiency measured by realistic brain phantom modelling of the surgical cavity was 99.4%. This phantom also demonstrated the ability of the probe to detect tumour discs as small as 5 mm in diameter (20 mg) for tumour-to-background ratios higher than 3:1 and with an acquisition time around 4 s at each scanning step. These results indicate that our detector could be a useful complement to existing techniques for the accurate excision of brain tumour tissue and more generally to improve the efficiency of radio-guided cancer surgery.

    Aim: The main objective of the study was to describe the use of skin fold advancement flaps (SFAFs) and other reconstructive techniques for closure of large skin defects following mammary tumor excision in dogs. Materials and Methods: Twelve dogs underwent reconstruction of large ventral skin defects following mammary tumor excision with wide margins. Skin fold flaps (flank fold flap and elbow fold flap) were elevated from the flank and elbow region, respectively, and transposed and sutured onto the large ventral skin defect following mastectomy in all the dogs. In addition to the skin fold flaps, other reconstructive techniques such as undermining, walking sutures, and tension-relieving suture techniques were followed during surgery in the closure of large skin defects without skin tension and compromising limb mobility. The skin flap viability was assessed subjectively by gross observation of the flap such as color, temperature, capillary perfusion, and cosmetic appearance, and scoring (1-4) was done. Tissue samples were collected from a surgical site on days 3, 6, and 12 post-operatively for histopathological evaluation and healing status of the skin flap. Results: All the surgical wounds healed primarily, without any major complications and the skin flap remained healthy throughout the healing process post-operatively. Distal flap necrosis was noticed in one case and necrosis of skin flap between two suture lines was noticed in another case in which the necrotized distal portion healed by secondary intention after 7 days. The mean survival of subdermal plexus flap in the above cases was 98% which was a subjective evaluation based on surface area of the skin defect measured by Image’ J software and the flap dimensions. The average healing of skin flap in days was 14.91±0.86. Conclusion: The SFAFs along with other reconstructive techniques help in the reconstruction of large ventral skin defects following mastectomy in dogs without much compromising limb

  14. Product analysis and initial reliability testing of the total mesorectal excision-quality assessment instrument. (United States)

    Simunovic, Marko R; DeNardi, Franco G; Coates, Angela J; Szalay, David A; Eva, Kevin W


    Product analysis of rectal cancer resection specimens before specimen fixation may provide an immediate and relevant evaluation of surgical performance. We tested the interrater reliability (IRR) of a product analysis tool called the Total Mesorectal Excision-Quality Assessment Instrument (TME-QA). Participants included two gold standard raters, five pathology assistants, and eight pathologists. Domains of the TME-QA reflect total mesorectal excision principles including: (1) completeness of mesorectal margin; (2) completeness of mesorectum; (3) coning of distal mesorectum; (4) physical defects; and (5) overall specimen quality. Specimens were scored independently. We used the generalizability theory to assess the tool's internal consistency and IRR. There were 39 specimens and 120 ratings. Mean overall specimen quality scores for the gold standard raters, pathologists, and assistants were 4.43, 4.43, and 4.50, respectively (p > 0.85). IRR for the first nine items was 0.68 for the full sample, 0.62 for assistants alone, 0.63 for pathologists alone, and 0.74 for gold standard raters alone. IRR for the item overall specimen quality was 0.67 for the full sample, 0.45 for assistants, 0.80 for pathologists, and 0.86 for gold standard raters. IRR increased for all groups when scores were averaged across two raters. Assessment of surgical specimens using the TME-QA may provide rapid and relevant feedback to surgeons about their technical performance. Our results show good internal consistency and IRR when the TME-QA is used by pathologists. However, for pathology assistants, multiple ratings with the averaging of scores may be needed.

  15. Black-hole excision with multiple grid patches

    International Nuclear Information System (INIS)

    Thornburg, Jonathan


    When using black-hole excision to numerically evolve a black-hole spacetime with no continuous symmetries, most 3 + 1 finite differencing codes use a Cartesian grid. It is difficult to do excision on such a grid because the natural r = constant excision surface must be approximated either by a very different shape such as a contained cube, or by an irregular and non-smooth 'LEGO 1 sphere' which may introduce numerical instabilities into the evolution. In this paper I describe an alternate scheme which uses multiple {r x (angular coordinates)} grid patches, each patch using a different (nonsingular) choice of angular coordinates. This allows excision on a smooth r = constant 2-sphere. I discuss the key design choices in such a multiple-patch scheme, including the choice of ghost-zone versus internal-boundary treatment of the interpatch boundaries (I use a ghost-zone scheme), the number and shape of the patches (I use a 6-patch 'inflated-cube' scheme), the details of how the ghost zones are 'synchronized' by interpolation from neighbouring patches, the tensor basis for the Einstein equations in each patch, and the handling of non-tensor field variables such as the BSSN Γ-tilde i (I use a scheme which requires ghost zones which are twice as wide for the BSSN conformal factor φ as for Γ-tilde i and the other BSSN field variables). I present sample numerical results from a prototype implementation of this scheme. This code simulates the time evolution of the (asymptotically flat) spacetime around a single (excised) black hole, using fourth-order finite differencing in space and time. Using Kerr initial data with J/m 2 = 0.6, I present evolutions to t ∼> 1500m. The lifetime of these evolutions appears to be limited only by outer boundary instabilities, not by any excision instabilities or by any problems inherent to the multiple-patch scheme

  16. Tibial tuberosity excision for symptomatic Osgood-Schlatter disease. (United States)

    Flowers, M J; Bhadreshwar, D R


    A modified Ferciot procedure was used to excise the tibial tubercle in patients with persistently symptomatic Osgood-Schlatter disease. Forty-two knees in 35 patients were reviewed at a mean follow-up of 5 years to assess outcome. The results revealed relief of pain in 95% of patients and reduction of prominence in 85.5% with minimal complication, in particular no evidence of genu recurvatum. The pathogenesis of the condition is outlined, and some of the theories and treatment modalities discussed. Tibial tubercle excision is recommended as the treatment of choice in those few cases that fail with conservative treatment.

    Several blood conservation strategies have been tried with the purpose of reducing homologons blood transfusion. PATIENTS #ENTITYSTARTX00026; In a prospective randomized study, the potential benefits of acute normovolemic hemodilution (ANH) with autologous transfusion were investigated as a blood conservation technique in surgical excision of intracranial meningioma. Over a period of 2 years, 40 patients undergoing excision of intracranial meningioma were randomly assigned to two groups of 20 patients each. Group I (Control Group) received conventional homologous blood intraoperatively and were not subjected to ANH. In Group II (ANH Group), Acute Normovolemic Hemodilution was initiated to a target hematocrit of 30% after induction of anesthesia. Parameters studied included changes in hemoglobin, hematocrit and hemodynamic parameters. The mean value of blood withdrawn in ANH group was 802.5 ± 208 ml. This was replaced simultaneously with an equal volume of 6% Hydroxyethyl starch to maintain normovolemia. There was no statistically significant variation in mean hemoglobin levels between the two groups at various stages of study. Hematocrit decreased significantly in both the groups at various stages as compared to preoperative values , the decrease being more but insignificant in group II. Changes in heart rate and mean blood pressure were similar and without statistically significant differences in either group at various stages of study. The amount of surgical blood loss in group I was 835.29 ± 684.37 ml, as compared to 865 + 409.78 ml in group II. The difference was statistically insignificant (p>0.05). The mean volume of homologous blood transfused in group I was 864.71 ± 349.89 ml, as compared to 165 ± 299.6 ml in group II which was statistically significant (p<0.05). In group II (ANH Group) only 5 patients (25%) required homologous blood whereas in group I I all patients (100%) needed homologous blood. We conclude that acute normovolemic hemodilution up to

  1. Surgical endodontics. (United States)

    Carrotte, P


    Root canal treatment usually fails because infection remains within the root canal. An orthograde attempt at re-treatment should always be considered first. However, when surgery is indicated, modern microtechniques coupled with surgical magnification will lead to a better prognosis. Careful management of the hard and soft tissues is essential, specially designed ultrasonic tips should be used for root end preparation which should ideally be sealed with MTA. All cases should be followed up until healing is seen, or failure accepted, and should form a part of clinical audit.

  2. "The lobbying strategy is to keep excise as low as possible" - tobacco industry excise taxation policy in Ukraine (United States)


    Background Tobacco taxes are one of the most effective ways to reduce tobacco use. Transnational tobacco companies (TTCs) claim they wish to develop and secure excise systems that benefit both governments and the profitability of the companies themselves. The objective of the paper is to use the case of Ukraine, with its inconsistent history of excise tax changes in 1992-2008, to explore tobacco industry taxation strategies and tactics, and their implications for governmental revenues. Methods Details of tobacco industry policy on tobacco taxation in Ukraine were obtained by searching tobacco industry internal documents and various published reports. Results Even before entering the market in Ukraine, TTCs had made efforts to change the excise system in the country. In 1993-1994, TTCs lobbied the Ukrainian Government, and succeeded in achieving a lowering in tobacco tax. This, however, did not produce revenue increase they promised the Government. In 1996-1998, Ukrainian authorities increased excise several times, ignoring the wishes of TTCs, caused significant growth in revenue. Due to TTCs lobbying activities in 1999-2007 the tax increases were very moderate and it resulted in increased tobacco consumption in Ukraine. In 2008, despite the TTCs position, excise rates were increased twice and it was very beneficial for revenues. Conclusions The Framework Convention on Tobacco Control includes provisions both on tobacco taxation policy and on protection of public health policy from vested interests of tobacco industry. This paper provides arguments why tobacco taxation policy should also be protected from vested interests of tobacco industry. TTCs taxation strategy appears to be consistent: keep excise as low as possible. Apparent conflicts between TTCs concerning tax structures often hide their real aim to change tax structures for competing interests without increasing total tax incidence. Governments, that aim to reduce levels of tobacco use, should not allow

  3. Arthroscopic Excision of a Huge Ununited Ossicle Due to Osgood-Schlatter Disease in an Adult Patient. (United States)

    Zhi-Yao, L I


    Surgical excision of the ununited ossicles has been suggested for unresolved sequelae of Osgood-Schlatter disease in adults resistant to conservative measures. We report a case where arthroscopy was used to excise the ossicles. A bird eye view from the superolateral portal was helpful in the arthroscopic procedure for excision of the deep low lesion. A 32-year-old, male driver had anterior knee pain during walking and sports activity that had been treated conservatively for 3 months. On physical examination, there was a prominent tibial tubercle, but without palpable pain. There was obvious pain when the knee was approaching full extension. On image, a huge ununited ossicle was seen behind the patellar tendon, intruding into the joint space, and there was another two small ununited ossicles beneath the bow-shaped patellar tendon. Arthroscopy was performed through a three portals technique, and a bird eye view was achieved from the superolateral portal. The ossicles were separated from the surrounding soft tissue with a motorized shaver. The small ununited ossicles were removed by use of a grasper. The huge ossicle was removed by use of a motorized bur, and the contouring of the irregular surface of the tibial tubercle was performed. After 3 months, the patient returned to sports activities without any restrictions. This report shows that a huge ossicle can cause impingement in anterior knee compartment, and it can be easily removed arthroscopically under assistance of an additional portal.

  4. Comparison of postoperative quality of life for patients who undergo atrial myxoma excision with robotically assisted versus conventional surgery. (United States)

    Yang, Ming; Yao, Minghui; Wang, Gang; Xiao, Cangsong; Wu, Yang; Zhang, Huajun; Gao, Changqing


    Robotically assisted cardiac surgery is an alternative to conventional, open-chest surgery. Although studies have been done on the clinical effect, morbidity, and mortality of robotically assisted atrial myxoma excision, few have addressed surgical outcomes, such as pain, quality of life (QOL), and length of sick leave from work. In this study, our aim was to evaluate these clinical variables among patients after they undergo robotically assisted atrial myxoma excision surgery. Between January 2007 and January 2013, a total of 93 patients underwent either conventional sternotomy or robotically assisted atrial myxoma excision in our unit. The 36-item Medical Outcomes Study Short Form Survey was used to assess the clinical outcomes in these patients postoperatively, at day 30 and 6 months. The QOL scores for 7 of 8 variables in the robotically assisted group were significantly higher than those in the conventional group at postoperative day 30 (P myxoma surgery is excellent with the robotically assisted approach, which may enable early return to employment and satisfactory recovery.

  5. Anatomy of the transverse colon revisited with respect to complete mesocolic excision and possible pathways of aberrant lymphatic tumor spread. (United States)

    Stelzner, Sigmar; Hohenberger, Werner; Weber, Klaus; West, Nicholas P; Witzigmann, Helmut; Wedel, Thilo


    Although lymph node metastases to pancreatic and gastroepiploic lymph node stations in transverse colon cancer have been described, the mode of lymphatic spread in this area remains unclear. This study was undertaken to describe possible pathways of aberrant lymphatic spread in the complex anatomic area of the proximal superior mesenteric artery and vein, the greater omentum, and the lower pancreatic border. Abdominal specimens obtained from four cadaveric donors were dissected according to the principles of complete mesocolic excision. The vascular architecture of the transverse colon was scrutinized in search of possible pathways of lymphatic spread to the pancreatic and gastroepiploic lymph nodes. Vascular connections between the transverse colon and the greater omentum at the level of both the hepatic and the splenic flexures could be identified. In addition, small vessels running from the transverse mesocolon to the lower pancreatic border in the area between the middle colic artery and the inferior mesenteric vein were demonstrated. Moreover, venous tributaries to the gastrocolic trunk could be exposed to highlight its surgical importance as a guiding structure for complete mesocolic excision. The technical feasibility to clearly separate embryologic compartments by predefined tissue planes in complete mesocolic excision was confirmed. However, the vicinity of all three endodermal intestinal segments (foregut, midgut, and hindgut) obviously gives way to vascular connections that might serve as potential pathways for lymphatic metastatic spread of transverse colon cancer.

  6. Successful surgical repair of tricuspid valve endocarditis. (United States)

    Salhiyyah, Kareem; Senanayake, Eshan; Cooper, Graham J


    Surgical treatment of tricuspid valve endocarditis is challenging especially in intravenous drug users. We present a case of a 30-year-old male active drug user with anterior leaflet endocarditis treated successfully with valve repair. This was achieved through excision of the vegetation with part of the leaflet. Bovine pericardium was used to close the defect. The edges were reinforced with Teflon pledgeted polytetrafluoroethylene Gore-Tex neochordae (W.L. Gore & Associates, Flagstaff, AZ, USA). An annuloplasty ring was used to reinforce the whole annulus. Repair was competent and the patient recovered well. This technique is simple and effective and should be considered for similar cases.

    The incorporation of the nuclear medicine to the surgical current practice In the treatment of the cancer of breast, by means of the application of radioactive isotopes, have supposed a great achievement not only in the surgical and predicted results but also in the surgical skills more effective and less aggressive. The systematic research of the marking and extirpation of Sentinel Lymph Node is avoiding in the early cancer the linfadenectomy axilar. The application of the ROLL and SNOLL skills is being determinant in the extirpation with trustworthy margins of the non-palpable lesions cancer, with big safety instead harpoons that we used before.

    Nelson de Souza Liboni


    Full Text Available Objectives: To describe the results of the surgical technique of pilonidalcyst excision with margins and primary closure of the operative woundwith support suturing. Methods: Twenty-eight patients with pilonidaldisease admitted to a private clinic between 1999 and 2006 underwentsurgical treatment by means of an elliptical longitudinal medial incisionproportional to the palpable tumor size and excision of cyst with 2-cmmargins above, below and laterally, and primary closure of the wound.To reduce the tension in the operative wound, suturing was performed,with a single support stitch of horizontal U-shape. The patients werefollowed up for periods ranging from 6 months to 3 years. Results:Two patients developed abscesses at the surgical site (7.1%, andone required complete opening of the operative wound for drainage.Both underwent excision and primary closure again. The pathologicalexamination demonstrated that these were not cases of relapse, butof recurrent abscess. No cases of non-infected collection (seroma andhematoma, spontaneous dehiscence of the operative wound or diseaserecurrence were recorded. Conclusions: The technique of pilonidal cystexcision with margins and primary closure of the wound reinforcedwith support suturing seems to be attractive, since it is characterizedby low complexity and low infection rate. Studies with larger samplesare needed to validate this surgical technique.

  17. Microendoscopic excision of C2 osteoid osteoma: a technical report. (United States)

    Kulkarni, Arvind G; Dhruv, Abhilash N; Bassi, Anupreet J


    Case report and description of technique. To describe a microendoscopic posterior approach for excision of an osteoid osteoma of C2. Microendoscopic techniques are widely used in the management of degenerative disorders of the spine. This is the first report of their use in the management of an osteoid osteoma via the posterior approach. A 12-year-old-boy presented with left-sided neck pain of 3-month duration. Investigations revealed an osteoid osteoma of C2 lamina-lateral mass complex. The patient underwent a posterior microendoscopic excision using 18-mm diameter METRx system (Medtronic Sofamor Danek, Memphis, TN) of tubular retractors. A postoperative computed tomographic scan was done and preoperative and postoperative visual analogue scale and Neck Disability Index were evaluated. The patient was periodically followed up for 1 year. The postoperative computed tomographic scan revealed complete excision of the tumor. The visual analogue scale score for neck pain improved from 3/5 (preoperative) to 0/5 (postoperative) and Neck Disability Index from 33.33 (preoperative) to 0 (postoperative) at 1-year follow-up. Microendoscopic techniques can be extended to excise lesions of the spine. It is a safe procedure in experienced hands. The advantages are minimal morbidity, minimal postoperative pain and discomfort, less analgesic dependence, and better cosmesis. The authors recommend this technique for accessible lesions involving the spine.

  3. Loop electrosurgical excision procedure in vulvar intraepithelial neoplasia treatment. (United States)

    Vlastos, Anne-Thérèse; Levy, Larry B; Malpica, Anais; Follen, Michele


    OBJECTIVE.: Our objective was to compare by response rate the therapeutic options of loop electrosurgical excision procedure (LEEP), laser therapy, and wide local excision in managing high-grade vulvar intraepithelial neoplasia in a pilot study for a randomized clinical trial. MATERIALS AND METHODS.: Between 1995 and 1999, 109 patients presenting with vulvar lesions were registered at a comprehensive cancer center and 2 associated colposcopy clinics. From these 109, we identified 74 patients with lesions histologically proven to be vulvar intraepithelial neoplasia who underwent treatment with CO2 laser, wide local excision, or LEEP. Clinical and pathological features were reviewed retrospectively. Wilcoxon rank sum test and life table analyses were used to compare groups. Response rates for this retrospective study will be used to calculate the sample size for a prospective clinical trial. RESULTS.: Our population was similar to others reported in the literature in age, range of diagnoses, and follow-up. Only 1 of 74 patients (1%) had invasive cancer. In a subset of 62 patients treated for the first time, LEEP and wide local excision were equal in their ability to achieve complete response. Laser ablation was the least successful of all methods (10/20 with laser, 3/20 with LEEP, and 2/22 with wide local excision experienced recurrences [p = .04]). No statistically significant differences among the 3 were noted in time to recurrence (p = .24). Age, age at first intercourse, and number of sexual partners were not correlated with recurrence and did not confound the results. Using a chi approximation, an alpha error of 0.05, and a power of 0.80, researchers should enroll 25 patients per arm if improvement over standard therapy is expected to be 40%, 45 if expected to be 30%, and 95 if expected to be 20%. CONCLUSIONS.: Because of differences in recurrence rate and length of hospital stay and indications of potential differences in cost found in this pilot, LEEP merits

  4. Does the insertion of more than one wire allow successful excision of large clusters of malignant calcification?

    Energy Technology Data Exchange (ETDEWEB)

    Cordiner, C.M.; Litherland, J.C.; Young, I.E


    AIM: To determine whether the insertion of more than one localization wire for larger areas of malignant microcalcification reduces the need for re-excision. METHOD: This is a retrospective study of 101 cases of malignant calcifications preoperatively marked by one or more wires. Surgical and histopathology data were obtained from hospital records. Mammograms and specimen radiographs were evaluated without knowledge of the eventual outcome, i.e., whether further surgery was required or not. All cases had a preoperative diagnosis of malignancy. RESULT: In this study the group of patients in which two or more wires were inserted had mammographically larger lesions (p < 0.000001) but did not have a greater chance of needing re-excision (p = 0.822). Mammograms that demonstrated flecks of microcalcification outlying the main cluster were also more likely to require further surgery (p < 0.01). Calcifications associated with high-grade ductal carcinoma in situ (DCIS) had three times the risk of requiring further surgery (p < 0.01). However, as reported in other studies re-excision was not related to breast size (p = 0.63) [Kollias J, Gill PG, Beamond B, Rossi H, Langlois S, Vernon-Roberts E. Clinical and radiological predictors of complete excision in breast-conserving surgery for primary breast cancer. Aust N Z J Surg 1998;68:702-6]. CONCLUSION: It was previously suggested that the risk of re-excision for DCIS is related to the size of the initial lesion [Cheng L, Al-Kaisi NK, Gordon NH, Liu AY, Gebrail F, Shenk RR. Relationship between the size and margins of ductal carcinoma in situ of the breast and residual disease. J Nat Cancer Inst 1997;89:1356-60]. However, in the present study larger clusters of microcalcification that have been 'bracketed' by two or more wires do not appear to have a greater requirement for re-excision. Grading of the malignant microcalcifications preoperatively may encourage the surgeon to take a wider margin. Careful examination of

  5. Os Trigonum Excision in Dancers via an Open Posteromedial Approach. (United States)

    Heyer, Jessica H; Rose, Donald J


    An os trigonum is a potential source of posterior ankle pain in dancers, often associated with flexor hallucis longus (FHL) pathology. Options for operative excision include open excision, subtalar arthroscopy, and posterior endoscopy. The purpose of this paper was to present a series of dancers who underwent excision of a symptomatic os trigonum via an open posteromedial approach. This study is a retrospective case series of 40 ankles in 38 dancers who underwent os trigonum excision via an open posteromedial approach with FHL tenolysis between 2000 and 2013. All patients were interviewed and charts retrospectively analyzed. Collected variables included pre- and postoperative pain level, time to return to dance, and subjective satisfaction. The average age was 19.2 years; ballet was the primary dance form in 36 (95%) of patient-cases. Eight (20%) of the patient-cases were professional dancers, and 30 (75%) were students or preprofessional dancers. Average preoperative pain level was 7.7/10, which decreased to 0.6/10 postoperatively. Seventeen (42.5%) experienced concurrent preoperation-associated FHL symptomatology, all of whom experienced relief postoperatively. The average time to return to dance was 7.9 weeks, and time to pain-free dance was 17.7 weeks. Of the 37 patient-cases desiring to return to dance, 35 (94.6%) returned to their preoperative level of dance. There were no neurovascular or other major complications. Four (10%) had minor wound complications that resolved, and 38 cases (95%) considered the procedure a success. Open posteromedial excision of an os trigonum in dancers provided satisfactory pain relief, return to dance, and complication rates compared to other approaches, and allowed for identifying and treating any associated FHL pathology. Level IV, retrospective case series.

  6. Complete mesocolic excision an assessment of feasibility and outcome. (United States)

    Bertelsen, Claus Anders


    Surgery is the most important factor for radical treatment of colon cancer, and the long-term prognosis can be improved by improving the surgical treatment without increased risk of perioperative mortality. Complete mesocolic excision (CME), in which more extensive lymph node (LN) dissection is performed, has been shown in single-centre studies with historical controls to be associated with better oncological outcome. However, better evidence is needed. The main purpose of this PhD thesis was to investigate whether CME could be implemented in a colorectal surgical department in Denmark, whether more extensive dissection could demonstrate LN metastases outside the mesocolon, and to demonstrate a possible association between CME and improved oncological results without increased risk of perioperative mortality. This thesis includes five articles. Two articles (IV and V) are based on the population of patients undergoing elective resection for colon cancer in the Capital Region from June 2008 to December 2013. Two articles (II and III) are based on data from the local colon database in Hillerød, and the last article (I) is a systematic review concerning the risk of metastases from colon cancer to the central LNs in the mesocolon. Article I found a risk of metastases in central LNs to be reported in 1-22% of the cases of right-sided colon cancers, and in up to 12% of the cases with sigmoid tumours. The populations included and methods used in the studies were very heterogeneous and no definitive conclusions can be drawn. It was shown in article II that the surgical quality, i.e. quality of the specimens assessed by the pathologists, improved with implementation of CME in Hillerød. The vascular tie was higher, and the implementation was not associated with an increased risk of perioperative mortality. Article III demonstrated a risk of LN metastases in the gastrocolic ligament along the stomach for tumours located in the transverse colon, in the ascending or

    Full Text Available A patient undergoing surgery faces great physiologic and psychologic stress. so nutritional demands are greatly increased during this period and deficiencies can easily develop. If these deficiencies are allowed to develop and are not in screening, serious malnutrition and clinical problem can occur. Therefore careful attention must be given to a patient's nutritional status in preparation of surgery, as well as to the individual nutritional needs. If these needs are met, complications are less likely developing. Natural resources provide for rapid recovery. Proper nutrition can speed healing in surgical patients with major trauma, severe malnutition, burns, and other severe illnesses. New techniques for tube feeding, intravenous nutrition for patients with serious weight loss due to gastrointestinal disorders, and use of supplements can hasten wound healing and shorten recovery times.

  8. Antibiotics for infection prevention after excision of the cervical transformation zone. (United States)

    Kietpeerakool, Chumnan; Chumworathayi, Bandit; Thinkhamrop, Jadsada; Ussahgij, Butsakorn; Lumbiganon, Pisake


    Excision of the transformation zone of the cervix is the most commonly used approach to treat cervical precancerous lesions (cervical intraepithelial neoplasia (CIN)) to reduce the risk of developing cervical cancer. As the excision of the transformation zone leaves a raw area on the cervix, there is a risk of infection following the procedure. The incidence of infection after cold knife conization (CKC) is 36%, whereas the incidence for large loop excision of the transformation zone (LLETZ, also known as loop electrical excision procedure (LEEP)) is much lower (0.8% to 14.4%). Prophalytic antibiotics may prevent an infection developing and are often prescribed for CKC. However, there are no formal recommendations regarding the use of prophylactic antibiotics for infection prevention in women undergoing surgical excisional treatment for cervical precancerous lesions. To evaluate the effectiveness and safety of antibiotics for infection prevention following excision of the cervical transformation zone. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2016, Issue 4), MEDLINE, Embase, LILACS to May 2016. We also checked registers of clinical trials, citation lists of included studies, key textbooks and previous systematic reviews for potentially relevant studies SELECTION CRITERIA: We included randomised controlled trials (RCTs) evaluating the effectiveness and safety of prophylactic antibiotics versus a placebo or no treatment in women having excision of the cervical transformation zone, regardless of the type of surgical excisional method used. We used standard methodological procedures expected by Cochrane. Two review authors independently selected potentially relevant trials, extracted data, and assessed risk of bias, compared results and resolved disagreements by discussion. We contacted investigators for additional data, where possible. Of the 370 records that we identified as a result of the search (excluding duplicates), we regarded

  11. Midsubstance Tendinopathy, Surgical Management. (United States)

    DeCarbo, William T; Bullock, Mark J


    Noninsertional Achilles tendinopathy often responds to nonoperative treatment. When nonoperative treatment fails, the clinician must distinguish between paratendinopathy and noninsertional tendinopathy. In paratendinopathy, myofibroblasts synthesize collagen, causing adhesions, and the paratenon may be released or excised. If a core area of tendinopathy is identified on MRI, the area is excised longitudinally and repaired with a side-to-side suture. If greater than 50% of the tendon diameter is excised, the authors recommend a short flexor hallucis longus tendon transfer with an interference screw. A turndown flap of the gastrocnemius aponeurosis is also described with good results. Copyright © 2016 Elsevier Inc. All rights reserved.

  12. Development and evaluation of a connective tissue phantom model for subsurface visualization of cancers requiring wide local excision (United States)

    Samkoe, Kimberley S.; Bates, Brent D.; Tselepidakis, Niki N.; DSouza, Alisha V.; Gunn, Jason R.; Ramkumar, Dipak B.; Paulsen, Keith D.; Pogue, Brian W.; Henderson, Eric R.


    Wide local excision (WLE) of tumors with negative margins remains a challenge because surgeons cannot directly visualize the mass. Fluorescence-guided surgery (FGS) may improve surgical accuracy; however, conventional methods with direct surface tumor visualization are not immediately applicable, and properties of tissues surrounding the cancer must be considered. We developed a phantom model for sarcoma resection with the near-infrared fluorophore IRDye 800CW and used it to iteratively define the properties of connective tissues that typically surround sarcoma tumors. We then tested the ability of a blinded surgeon to resect fluorescent tumor-simulating inclusions with ˜1-cm margins using predetermined target fluorescence intensities and a Solaris open-air fluorescence imaging system. In connective tissue-simulating phantoms, fluorescence intensity decreased with increasing blood concentration and increased with increasing intralipid concentrations. Fluorescent inclusions could be resolved at ≥1-cm depth in all inclusion concentrations and sizes tested. When inclusion depth was held constant, fluorescence intensity decreased with decreasing volume. Using targeted fluorescence intensities, a blinded surgeon was able to successfully excise inclusions with ˜1-cm margins from fat- and muscle-simulating phantoms with inclusion-to-background contrast ratios as low as 2∶1. Indirect, subsurface FGS is a promising tool for surgical resection of cancers requiring WLE.

    Ifeacho, S N; Bajaj, Y; Jephson, C G; Albert, D M


    An assessment of the rate of surgical site infections associated with elective paediatric otolaryngology surgical procedures. Prospective data was collected for a 3-week period for all children undergoing surgery where either mucosa or skin was breached. The parents of the children were requested to complete a questionnaire at 30 days after the operation. Data was collected on 80 consecutive cases. The majority of cases were admitted on the day of the procedure. The procedures included adenotonsillectomy (24), grommets (12), cochlear implantation (6), bone-anchored hearing aid (2), submandibular gland excision (1), branchial sinus excision (1), cystic hygroma excision (3), nasal glioma excision (1), microlaryngobronchoscopy (13), tracheostomy (3) and other procedures (14). Nearly half the cases had more than one operation done at the same time. 26/80 (32.5%) patients had a temporary or permanent implant inserted at the time of operation (grommet, bone-anchored hearing aid, cochlear implant). 25/80 (31%) operative fields were classed as clean and 55/80 (68.7%) as clean contaminated operations. The duration of the operation varied from 6 min to 142 min. Hospital antibiotic protocol was adhered to in 69/80 (86.3%) cases but not in 11/80 cases. In our series, 3/80 (3.7%) patients had an infection in the postoperative period. Surgical site infections do occur at an appreciable rate in paediatric otolaryngology. With the potential for serious consequences, reduction in the risk of surgical site infections is important. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Wang, Kai; Wang, Zhi; Huang, Weiqing


    Halo congenital melanocytic nevus (CMN) associated with vitiligo is rare, especially with regard to CMN excision. Only two reports of excision of halo CMN following repigmentation of vitiligo are found in the literature. We present a case of a girl with halo CMN and periorbital vitiligo. The halo CMN was excised and followed by spontaneous improvement of vitiligo. The result suggests excision of the inciting lesion may be a promising way to control vitiligo. © 2015 Wiley Periodicals, Inc.

  17. Trends in inpatient setting laminectomy for excision of herniated intervertebral disc: Population-based estimates from the US nationwide inpatient sample. (United States)

    Walcott, Brian P; Hanak, Brian W; Caracci, James R; Redjal, Navid; Nahed, Brian V; Kahle, Kristopher T; Coumans, Jean-Valery C E


    Herniated intervertebral discs can result in pain and neurological compromise. Treatment for this condition is categorized as surgical or non-surgical. We sought to identify trends in inpatient surgical management of herniated intervertebral discs using a national database. Patient discharges identified with a principal procedure relating to laminectomy for excision of herniated intervertebral disc were selected from the Nationwide Inpatient Sample (Healthcare Cost and Utilization Project - Agency for Healthcare Research and Quality, Rockville, MD), under the auspices of a data user agreement. These surgical patients did not undergo instrumented fusion. To account for the Nationwide Inpatient Sample weighting schema, design-adjusted analyses were used. The estimates of standard errors were calculated using SUDAAN software (Research Triangle International, NC, USA). This software is based on the International Classification of Diseases, 9(th) Revision, Clinical Modification (ICD-9-CM); a uniform and standardized coding system. Using International Classification of Disease 9(th) Revision clinical modifier (ICD-9 CM) procedure code 80.51, we were able to identify disc excision, in part or whole, by laminotomy or hemilaminectomy. The incidence of laminectomy for the excision of herniated intervertebral disc has decreased dramatically from 1993 where 266,152 cases were reported [CI = 22,342]. In 2007, only 123,398 cases were identified [CI = 12,438]. The average length of stay in 1993 was 4 days [CI = 0.17], and in 2007 it decreased to just 2 days [CI = 0.17]. Both these comparisons were significantly different at P herniated intervertebral disc has decreased significantly. This trend is multifactorial and is likely related to developments in outcomes research, the growing popularity of alternative procedures (intervertebral instrumented fusion), and transition to an ambulatory setting of surgical care.

  18. Surgical management of generalized gingival enlargement - a case series

    International Nuclear Information System (INIS)

    Akhtar, M.U.; Nazir, A.; Montmorency College of Dentistry, Lahore; Kiran, S.; Montmorency College of Dentistry, Lahore


    Generalized gingival enlargement is characterized by massive and exuberant gingival overgrowth that poses social, aesthetic, phonetic and functional problems for the patient. Therefore, it requires meticulous management. Objective: To describe the surgical management of generalized gingival enlargement by electrosurgical excision of patients presenting to a tertiary care centre. Study Design: Case series. Materials and Methods: The study was conducted at the Department of Oral and Maxillofacial Surgery, de'Montmorency College of Dentistry, Lahore, from January 2010 to December 2012. A total of sixteen patients were operated by using electrosurgical approach under general anaesthesia for surgical excision of generalized gingival enlargement. Results: All of the sixteen patients, 11 males and 5 females, showed excellent healing postoperatively without any recurrent gingival overgrowth. Discussion: To the best of our knowledge, the current study presents the largest case series of generalized gingival enlargement. Most of these cases were with massive disease due to lack of information of the study population about their disease, delay in referral by the general dental practitioners, painless and innocent nature of the problem. Early referral of such patients to tertiary care centers can prevent the patients from social and psychological embarrassment. Conclusion: Electrosurgical excision is an excellent surgical technique for management of generalized gingival enlargement. Moreover, cross comparative studies are required to establish some diagnostic and therapeutic standards for such patients. (author)

A control group was selected from 18 consecutive patients who underwent an isolated atrial myxoma excision via conventional sternotomy. Preoperative patient characteristics were similar between the two study groups. Postoperative health-related quality of life (HRQoL) was also evaluated. All robotic operations were completed successfully using the da Vinci™ telesurgical system. There was no mortality in either of the two study groups. Procedure, cardiopulmonary bypass, aortic occlusion, and ventilation times were shorter in the sternotomy group when compared to the robotic group. Length of stay was statistically significantly shorter in the robotically assisted group. Postoperative quality of life did not differ between the two study groups. We conclude that robotically assisted surgery is a feasible method for treating atrial myxomas.

  3. Excise Tax Avoidance: The Case of State Cigarette Taxes (United States)

    DeCicca, Philip; Kenkel, Donald; Liu, Feng


    We conduct an applied welfare economics analysis of cigarette tax avoidance. We develop an extension of the standard formula for the optimal Pigouvian corrective tax to incorporate the possibility that consumers avoid the tax by making purchases in nearby lower-tax jurisdictions. To provide a key parameter for our formula, we estimate a structural endogenous switching regression model of border-crossing and cigarette prices. In illustrative calculations, we find that for many states, after taking into account tax avoidance the optimal tax is at least 20 percent smaller than the standard Pigouvian tax that simply internalizes external costs. Our empirical estimate that tax avoidance strongly responds to the price differential is the main reason for this result. We also use our results to examine the benefits of replacing avoidable state excise taxes with a harder-to-avoid federal excise tax on cigarettes. PMID:24140760

    Santosh Kumar Sinha


    Full Text Available Hydatid disease is still prevalent in developing countries, and isolated cardiac hydatid cysts are the rarest presentation. We report a 40-year-old nondiabetic, nonhypertensive female who presented with low-grade fever for 2 months shortness of breath and orthopnea for 2 weeks. Transthoracic echocardiography revealed a large, round cystic lesion with multiple daughter cysts without any obvious intraluminal detached membranes with mass effect on the left ventricular outflow tract. After total excision, residual tissue was closed with Teflon patch. Germinative membrane and hundreds of daughter cysts were seen. Following total excision of the cyst from myocardium, myocardial cavity was washed thoroughly with 10% Betadine solution. Pathological examination confirmed the diagnosis of hydatid cyst. Preoperatively started albendazole was continued for 4 weeks even after the operation. On follow-up after 4 weeks, the patient is doing well and cardiac imaging showed normal contours of the heart.

  6. Robot-Assisted Laparoscopic Excision of Ureteral and Ureteropelvic Junction Fibroepithelial Polyps in Children. (United States)

    Osbun, Nathan; Ellison, Jonathan S; Lendvay, Thomas S


    Fibroepithelial polyps of the ureter are a rare cause of asymptomatic and symptomatic upper urinary tract obstruction in children. While these lesions can often be managed endoscopically, large or multifocal polyps may preclude such an approach. We aim to describe our institutional experience with robot-assisted laparoscopic treatment of ureteral polyps and show that a robotic approach is an effective alternative for large or multifocal polyps. Four children were identified with ureteral polyps over a 5-year period and underwent transperitoneal robot-assisted laparoscopic excision. Patients presented with flank pain and/or worsening hydronephrosis. All patients were evaluated preoperatively with ultrasound and Tc99m-mercaptoacetyltriglycine (MAG3) diuretic renogram or MR urogram. Retrograde pyelography corroborated the diagnosis of ureteral polyps. We reviewed the charts of these patients and compared the specific robotic approach for each patient, length of hospitalization, surgical complications, need for additional procedures, and resolution of symptoms and hydronephrosis. In one patient, more than 20 polyps were identified over a long ureteral segment and all were excised; for the remaining three patients, 1 to 2 polyps were found. Mean postoperative length of stay was 1.5 days. One patient developed a ureteral stricture requiring repeat ureteroureterostomy, and another patient required repeat retrograde pyelography for gross hematuria that occurred several months after surgery. No polyps or obstruction was observed on retrograde pyelography in these patients. Mean duration of follow-up was 29 months (9-62 months). Symptoms and degree of hydronephrosis have improved in the three patients who have been followed for at least 12 months. Robot-assisted laparoscopy is a safe and feasible alternative to endoscopic treatment of fibroepithelial ureteral polyps. The robotic platform may be preferred in cases of multifocal or large ureteral polyps, or in cases in which a

  7. Increased Ac excision (iae): Arabidopsis thaliana mutations affecting Ac transposition

    Jarvis, P.; Belzile, F.; Page, T.; Dean, C.


    The maize transposable element Ac is highly active in the heterologous hosts tobacco and tomato, but shows very much reduced levels of activity in Arabidopsis. A mutagenesis experiment was undertaken with the aim of identifying Arabidopsis host factors responsible for the observed low levels of Ac activity. Seed from a line carrying a single copy of the Ac element inserted into the streptomycin phosphotransferase (SPT) reporter fusion, and which displayed typically low levels of Ac activity, were mutagenized using gamma rays. Nineteen mutants displaying high levels of somatic Ac activity, as judged by their highly variegated phenotypes, were isolated after screening the M2 generation on streptomycin-containing medium. The mutations fall into two complementation groups, iae1 and iae2, are unlinked to the SPT::Ac locus and segregate in a Mendelian fashion. The iae1 mutation is recessive and the iae2 mutation is semi-dominant. The iae1 and iae2 mutants show 550- and 70-fold increases, respectively, in the average number of Ac excision sectors per cotyledon. The IAE1 locus maps to chromosome 2, whereas the SPT::Ac reporter maps to chromosome 3. A molecular study of Ac activity in the iae1 mutant confirmed the very high levels of Ac excision predicted using the phenotypic assay, but revealed only low levels of Ac re-insertion. Analyses of germinal transposition in the iae1 mutant demonstrated an average germinal excision frequency of 3% and a frequency of independent Ac re-insertions following germinal excision of 22%. The iae mutants represents a possible means of improving the efficiency of Ac/Ds transposon tagging systems in Arabidopsis, and will enable the dissection of host involvement in Ac transposition and the mechanisms employed for controlling transposable element activity

    The regulatory framework concerning the new excise duty appears as complex and unfinished, raising more questions than providing answers. The duty will entail a significant expense item for the businesses liable to register and it is therefore important to have an overview of how the regulatory framework should be understood. Errors made since 1 January 2007 may lead to future reassessments of duties, with interest (author) (ml)

  11. [Efficacy of the surgical treatment for malignant heart tumors]. (United States)

    Vitovskiĭ, R M


    Peculiarities of malignant cardiac tumors surgical treatment were studied, basing on analysis of 33 observations. Rhabdomyosarcoma was diagnosed in 9 patients, angiosarcoma--in 11, leyomyosarcoma--in 6, malignant mixoma--in 4, fibrosarcoma, chondrosarcoma and liposarcoma--each as a single observation. Special attention was paid to guarantee the maximal radicalism in the tumor excision, what made it necessary in 8 observations to perform additive surgical procedures, such as interatrial septum and atrial walls plasty, plastic operations on cardiac valves and the valves prostheses. The operation volume extension did not influence significantly its immediate result.

    Khan, F. A.; Niazi, S. P. K.; Khan, D. A.


    Objective: To compare the corneal astigmatism before and after the excision of pterygium and also to determine the correlation of pterygium size with the postoperative corneal astigmatism. Study Design: Cross-sectional interventional study. Place and Duration of Study: Eye Department, Combined Military Hospital, Abbottabad, from May 2011 to March 2012. Methodology: Thirty patients underwent pterygium excision. Pre-operatively Snellen visual acuity, manifest refraction and slit lamp examination was done. The size of the pterygium was recorded in mm by projecting a horizontal slit lamp beam from the limbus to the apex. All the pterygium were equal to or greater than 2.5 mm. Keratometry was performed with an automated keratometer. Keratometric data was recorded pre-operatively and at 28 days postoperatively. Wilcoxon signed rank test was used for comparing the pre-operative and the postoperative corneal astigmatism. Spearman's rank order was calculated to observe correlation of pterygium size with the postoperative astigmatism. Results: The median (mean rank) pre-operative astigmatism of 2.25 (15.50) reduced to a median (mean rank) postoperative astigmatism of 1.30 (14.96). This decrease in the postoperative astigmatism was statistically significant (p < 0.001). There was a statistically non-significant correlation between the postoperative astigmatism and the pterygium size (rs = -0.29, p = 0.12). Conclusion: Pterygium excision caused significant reduction in corneal astigmatism. (author)

  13. Effect of chalazion excision on refractive error and corneal topography. (United States)

    Bagheri, Abbas; Hasani, Hamid R; Karimian, Farid; Abrishami, Mohammad; Yazdani, Shahin


    To evaluate refractive and corneal topographic changes following excision of chalazia. This prospective noncomparative quasi-experimental clinical trial includes consecutive patients older than 7 years with chalazia of minimum duration of 1 month who underwent excision of the lesions by an internal or external approach. Overall, 253 lids from 228 eyes of 195 patients including 110 female subjects with mean age of 31-/+14 years (range 7-71) were studied. Mean duration of presenting symptoms was 4-/+2.8 months (range 1-24). Lesions were equally distributed in medial, central, and lateral areas of the eyelids. The chalazia were single in 172 (88.2%) and multiple in 23 (11.8%) patients. Mean change in best-corrected visual acuity, spherical equivalent refractive error, and difference of keratometry (corneal astigmatism) were 0.0004-/+0.007 logMAR (p=0.3), -0.06-/+0.6 D (p=0.1), and 0.34-/+0.35 (pChalazion excision can decrease corneal astigmatism and irregularity, which is more prominent in single, firm, and central upper lid lesions. These findings may have implications in pediatric patients at risk for amblyopia.

  14. Excised larynx evaluation of subthyroid cartilage approach to medialization thyroplasty. (United States)

    Thompson, James D; Hoffman, Matthew R; Scholp, Austin; Devine, Erin E; Jiang, Jack J; McCulloch, Timothy M


    To describe an alternative approach to medialization thyroplasty involving dissection underneath the thyroid cartilage with placement of a Gore-Tex implant, and to evaluate its effect on a range of phonatory measures using an excised canine larynx model. Animal model. On each of eight excised canine larynges, the conditions of normal, paralysis, medialization thyroplasty by standard transthyroid cartilage approach, and medialization thyroplasty by experimental subthyroid cartilage approach were performed. Aerodynamic, acoustic, and mucosal wave parameters were measured for each condition. Compared to the vocal fold paralysis state, both the transthyroid and subthyroid approaches for Gore-Tex insertion resulted in significant decreases in phonation threshold pressure and phonation threshold flow. Both approaches also significantly decreased percent jitter, decreased percent shimmer, and improved signal-to-noise ratio. The mucosal wave was preserved after insertion of the Gore-Tex implant for both approaches. For all the phonatory measures except phonation threshold flow, there were no significant differences between the transthyroid and subthyroid approaches. Gore-Tex implantation via a subthyroid approach in an excised canine larynx model can produce effective medialization, preserve the mucosal wave, and significantly improve aerodynamic and acoustic parameters without meaningful difference compared to a traditional transthyroid approach. The subthyroid approach does not require creation of a thyroid cartilage window and could be a potentially valuable alternative method of performing medialization thyroplasty. NA.

  15. Surgical Treatment of Classic Kaposi’s Sarcoma in the Lower Extremity

    Directory of Open Access Journals (Sweden)

    Adem Topkara


    Full Text Available Objective: Classic Kaposi’s sarcoma is an indolent, angioproliferative tumor that is usually observed in the lower extremities of elderly men. Depending on their stages, skin lesions are maculonodular or vegetative ulcerated masses. Visceral organ or lymph node involvement may rarely occur. There is no gold standard treatment for local diseases. Surgical excision, radiotherapy, chemotherapy, and cryotherapy can be performed. This retrospective study aimed to evaluate the long-term results of surgical excision and skin graft repair of stage I and II classic Kaposi’s sarcoma skin lesions around the foot and ankle. Material and Methods: Eleven patients were included. The patients’ age and gender, location of lesion, surgical treatment, follow-up period, and recurrence were evaluated by retrospectively examining patient records. For the surgical treatment, the lesion was excised with a 0.5-cm safe skin margin. The defect area was repaired with full-thickness skin grafts that were obtained from the inguinal region in all patients. Results: Eight of the patients were male and three were female. The average age of the patients was 69 (54–84 years. All patients were completely cured. The average follow-up period was 1.8 (1–3 years. No recurrence was observed in any of the patients at the end of the follow-up period. Conclusion: Classic Kaposi’s sarcoma skin lesions in the lower extremity can be completely cured by surgical excision, with no recurrence risk. After surgical excision, using a full-thickness skin graft for repairing primary cutaneous defects, particularly those in the soles, is a simple and reliable method.

    To explore the efficacies of treating patients with large area third-degree burns by tangential excision and skin grafting for subcutaneous tissue wounds. From January 2002 to December 2013, the medical records were retrospectively reviewed for 31 consecutive adult patients with a third-degree burn area exceeding 70% and undergoing tangential excision and skin grafting on subcutaneous tissue wound (TESGSTW) for the first time within 7 days postburn at Burn Center, Affiliated Jinan Central Hospital, Shandong University. For 31 patients, wounds with relative integrity eschar underwent TESGSTW by stages. Tourniquet was not used in some extremities. The relevant clinical data including patient condition on admission, causes of death, blood loss of tangential excision wound, surgical procedures and efficacies in cured group were analyzed. Average age, burn total area and third-degree burn area of 31 patients were (32.4 ± 12.8) years, (89.0 ± 6.2)% and (80.4 ± 7.6)% respectively. There were inhalation injury (n = 25, 80.6%) and early-stage shock before hospitalization (n = 22, 71.0%). Among 18 cured ones (58.1%), 2 patients had a third-degree burn area ≥ 90%. And 13 patients (41.9%) died and 10 of them died at 4 to 19 days postburn. Burn area was a risk factor of burn mortality. Sepsis and multiple organ dysfunction syndrome (MODS) were major mortality causes. Four patients died from early-stage sepsis. Within 14 days postburn, average blood loss volume per 1% tangential excision area in non-tourniquet group was slightly higher than that in the tourniquet group, but the difference was insignificant. For 18 cured patients, TESGSTW were performed 41 times. For 14 patients (77.8%), TESGSTW was performed twice. The average time of the first tangential excision was (4.1 ± 0.6) days postburn, the time interval between the first two tangential excisions was (6.4 ± 2.0) days, the first tangential excision area (33.8 ± 7.6)% and accumulated tangential excision area (58

    Transanal total mesorectal excision (taTME) is an emerging surgical technique for rectal cancer. However, the oncological and perioperative outcomes are controversial when compared with conventional laparoscopic total mesorectal excision (laTME). A systematic review and meta-analysis based on Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines was conducted in PubMed, Embase and Cochrane database. All original studies published in English that compared taTME with laTME were included for critical appraisal and meta-analysis. Data synthesis and statistical analysis were carried out using RevMan 5.3 software. A total of seven studies including 573 patients (taTME group = 270; laTME group = 303) were included in our meta-analysis. Concerning the oncological outcomes, no differences were observed in harvested lymph nodes, distal resection margin (DRM) and positive DRM between the two groups. However, the taTME group showed a higher rate of achievement of complete grading of mesorectal quality (OR = 1.75, 95% CI = 1.02-3.01, P = 0.04), a longer circumferential resection margin (CRM) and less involvement of positive CRM (CRM: WMD = 0.96, 95% CI = 0.60-1.31, P CRM: OR = 0.39, 95% CI = 0.17-0.86, P = 0.02). Concerning the perioperative outcomes, the results for hospital stay, intraoperative complications and readmission were comparable between the two groups. However, the taTME group showed shorter operation times (WMD = -23.45, 95% CI = -37.43 to -9.46, P <0.01), a lower rate of conversion (OR = 0.29, 95% CI = 0.11-0.81, P = 0.02) and a higher rate of mobilization of the splenic flexure (OR = 2.34, 95% CI = 0.99-5.54, P = 0.05). Although the incidence of anastomotic leakage, ileus and urinary morbidity showed no difference between the groups, a significantly lower rate of overall postoperative complications (OR = 0.65, 95% CI = 0.45-0.95, P = 0.03) was

    Siegel, Michael; Grundman, Jody; DeJong, William; Naimi, Timothy S; King, Charles; Albers, Alison B; Williams, Rebecca S; Jernigan, David H


    The authors investigated the relationship between state excise taxes and liquor prices in 8 states, using 2012 data for 45 brands. The authors made 6042 price observations among 177 liquor stores with online prices. Using a hierarchical model, the authors examined the relationship between excise taxes and product prices. State excise taxes were significantly related to liquor prices, with an estimated pass-through rate of 0.93. The proportion of price accounted for by excise taxes averaged 7.0%. The authors find that excise taxes do increase the price of alcohol, but states are not taking advantage of this opportunity to reduce alcohol-related morbidity and mortality.

  20. Presentation and Surgical Management of Duodenal Duplication in Adults

    Directory of Open Access Journals (Sweden)

    Caroline C. Jadlowiec


    Full Text Available Duodenal duplications in adults are exceedingly rare and their diagnosis remains difficult as symptoms are largely nonspecific. Clinical presentations include pancreatitis, biliary obstruction, gastrointestinal bleeding from ectopic gastric mucosa, and malignancy. A case of duodenal duplication in a 59-year-old female is presented, and her treatment course is reviewed with description of combined surgical and endoscopic approach to repair, along with a review of historic and current recommendations for management. Traditionally, gastrointestinal duplications have been treated with surgical resection; however, for duodenal duplications, the anatomic proximity to the biliopancreatic ampulla makes surgical management challenging. Recently, advances in endoscopy have improved the clinical success of cystic intraluminal duodenal duplications. Despite these advances, surgical resection is still recommended for extraluminal tubular duplications although combined techniques may be necessary for long tubular duplications. For duodenal duplications, a combined approach of partial excision combined with mucosal stripping may offer advantage.

  1. Acute felon and paronychia: Antibiotics not necessary after surgical treatment. Prospective study of 46 patients. (United States)

    Pierrart, Jérôme; Delgrande, Damien; Mamane, William; Tordjman, Daniel; Masmejean, Emmanuel H


    Paronychia and felon are the most common infections of the hand. Surgical treatment is required once an abscess develops, but systematic use of postoperative antibiotic therapy remains open for discussion. Antibiotics both favor the selection of resistant bacteria and increase the cost of treatment. To our knowledge, no study has demonstrated their benefit following excision, yet many practitioners prescribe them systematically and empirically. In our current practices, we do not use antibiotic coverage following excision of uncomplicated paronychia or felon (no signs of arthritis, osteitis, flexor tenosynovitis, lymphangitis), except in potentially at-risk patients (immunosuppressed, diabetic, cardiac valve prosthesis recipient). Since this approach seems to lead to good outcomes, our objective was to evaluate them clinically in this study. Our prospective study included 46 patients who were not considered at risk. There were 26 cases of paronychia, 3 cases of felon and 17 patients presenting both paronychia and felon. All cases were abscessed and uncomplicated. All patients underwent surgical excision, and none received postoperative antibiotics. Follow-up took place on the day after surgery, at days 7, 14, 21 and 45. The main criterion for evaluation was healing of the infection and the wound. We recorded 45 cases of healing with no complications and a single case of recurrence. Surgical excision of paronychia or felon without antibiotic coverage gives excellent results with only rare recurrence. The single failure can be attributed to inadequate excision. Antibiotic therapy has no role in managing uncomplicated felon or paronychia in patients who are otherwise not at risk. Successful treatment depends above all on the completeness of the surgical excision. Copyright © 2016 SFCM. Published by Elsevier Masson SAS. All rights reserved.

  2. Laparoscopic Excision Versus Ablation for Endometriosis-associated Pain: An Updated Systematic Review and Meta-analysis. (United States)

    Pundir, Jyotsna; Omanwa, Kireki; Kovoor, Elias; Pundir, Vishal; Lancaster, Gillian; Barton-Smith, Peter

    The aim of this study was to update the evidence on the surgical management of endometriosis-associated pain. Does laparoscopic excision offer any benefits over laparoscopic ablation? This is a systematic review and meta-analysis in which we searched MEDLINE, Embase, Institute for Scientific Information conference proceedings, the International Standard Randomised Controlled Trial Number registry, the Register and Meta-register for randomized controlled trials, the World Health Organization trials search portal, the Cochrane Library, and the British Library of electronic theses. Three randomized controlled trials were included, which enrolled 335 participants with a sample size per study ranging from 24 to 178 participants. Of these 3 studies, data from 2 could be pooled for meta-analysis. The primary outcome measure was the reduction in the visual analog scale score for dysmenorrhea. The secondary outcome measures included the reduction in the visual analog scale score for dyspareunia, dyschezia, and chronic pelvic pain and the reduction in Endometriosis Health Profile-30 core pain scores. The meta-analysis showed that the excision group had a significantly greater reduction in symptoms of dysmenorrhea (mean difference [MD] = 0.99; 95% confidence interval [CI], -0.02 to 2.00; p = .05) and dyschezia (MD = 1.31; 95% CI, 0.33-2.29; p = .009) compared with ablation. The symptoms of dyspareunia showed a nonsignificant benefit with excision (MD = 0.96; 95% CI, -0.07 to 1.99; p = .07). Data from 1 study showed a significant reduction in chronic pelvic pain (MD = 2.57; 95% CI, 1.27-3.87; p = .0001) and Endometriosis Health Profile-30 core pain scores (MD = 13.20; 95% CI, 3.70-22.70; p = .006) with the excision group compared with the ablation group. The limited available evidence shows that at 12 months postsurgery, symptoms of dysmenorrhea, dyschezia, and chronic pelvic pain secondary to endometriosis showed a significantly greater improvement with

  3. Excision of reprogramming transgenes improves the differentiation potential of iPS cells generated with a single excisable vector. (United States)

    Sommer, Cesar A; Sommer, Andreia Gianotti; Longmire, Tyler A; Christodoulou, Constantina; Thomas, Dolly D; Gostissa, Monica; Alt, Fred W; Murphy, George J; Kotton, Darrell N; Mostoslavsky, Gustavo


    The residual presence of integrated transgenes following the derivation of induced pluripotent stem (iPS) cells is highly undesirable. Here we demonstrate efficient derivation of iPS cells free of exogenous reprogramming transgenes using an excisable polycistronic lentiviral vector. A novel version of this vector containing a reporter fluorochrome allows direct visualization of vector excision in living iPS cells in real time. We find that removal of the reprogramming vector markedly improves the developmental potential of iPS cells and significantly augments their capacity to undergo directed differentiation in vitro. We further propose that methods to efficiently excise reprogramming transgenes with minimal culture passaging, such as those demonstrated here, are critical since we find that iPS cells may acquire chromosomal abnormalities, such as trisomy of chromosome 8, similar to embryonic stem cells after expansion in culture. Our findings illustrate an efficient method for the generation of transgene-free iPS cells and emphasize the potential beneficial effects that may result from elimination of integrated reprogramming factors. In addition, our results underscore the consequences of long-term culture that will need to be taken into account for the clinical application of iPS cells.

  4. Multilevel en bloc spondylectomy and chest wall excision via a simultaneous anterior and posterior approach for Ewing sarcoma. (United States)

    Samartzis, Dino; Marco, Rex A W; Benjamin, Robert; Vaporciyan, Ara; Rhines, Laurence D


    A case study of a patient with Ewing sarcoma of T8 and T9 with paravertebral and chest wall involvement, who underwent neoadjuvant chemotherapy and subsequent multilevel en bloc spondylectomy and chest wall excision using a simultaneous anterior and posterior approach. To show the feasibility of treating Ewing sarcoma of the thoracic spine with paravertebral and chest wall extension by multiagent chemotherapy followed by a multilevel en bloc spondylectomy and chest wall excision using a simultaneous anterior and posterior approach. Ewing sarcoma is a primary malignant bone tumor that occasionally involves the spinal column. Most patients with Ewing sarcoma of the spine are treated with systemic chemotherapy followed by definitive local control. Radiation therapy is the usual mode of local control in these patients because the spinal column has historically been considered a surgically inaccessible site where wide surgical margins are difficult to obtain. However, en bloc spondylectomy techniques have been described that can probably further decrease the risk of local recurrence, thereby minimizing or even eliminating the need for radiation therapy. To our knowledge, a combined en bloc spondylectomy and chest wall excision in a patient with Ewing sarcoma in the spine has not been previously reported. Neoadjuvant chemotherapy consisting of vincristine, doxorubicin, and cyclophosphamide was administered. After completion of the chemotherapy, an en bloc spondylectomy of T8 and T9 with removal of the chest wall was achieved using a simultaneous anterior and posterior approach to the spine. A stackable carbon fiber cage filled with autograft and allograft bone was inserted between T7 and T10. The spine was stabilized with anterior and posterior instrumentation. The chest wall was reconstructed with contoured polymethylmethacrylate and polypropylene (Marlex, Textile Development Associates, Inc., Franklin Square, NY) mesh. The patient maintained normal neurologic function

  5. Surgical treatment of basal cell carcinoma: an algorithm based on the literature* (United States)

    Luz, Flávio Barbosa; Ferron, Camila; Cardoso, Gilberto Perez


    Although basal cell carcinoma can be effectively managed through surgical excision, the most suitable surgical margins have not yet been fully determined. Furthermore, micrographic surgery is not readily available in many places around the world. A review of the literature regarding the surgical treatment of basal cell carcinoma was conducted in order to develop an algorithm for the surgical treatment of basal cell carcinoma that could help the choice of surgical technique and safety margins, considering the major factors that affect cure rates. Through this review, it was found that surgical margins of 4mm seem to be suitable for small, primary, well-defined basal cell carcinomas, although some good results can be achieved with smaller margins and the use of margin control surgical techniques. For treatment of high-risk and recurrent tumors, margins of 5-6 mm or margin control of the surgical excision is required. Previous treatment, histological subtype, site and size of the lesion should be considered in surgical planning because these factors have been proven to affect cure rates. Thus, considering these factors, the algorithm can be a useful tool, especially for places where micrographic surgery is not widely available. PMID:26131869

  6. Robot-assisted complete excision of choledochal cyst type I, hepaticojejunostomy and extracorporeal Roux-en-y anastomosis: a case report and review literature (United States)


    For Choledochal cyst type I, complete excision of cyst with Roux-en-Y hepaticojejunostomy anastomosis is the treatment of choice. It has been performed laparoscopically with the advancement of laparoscopic skill. Recently, a telemanipulative robotic surgical system was introduced, providing laparoscopic instruments with wrist-arm technology and 3-dimensional visualization of the operative field. We present a case of robot-assisted total excision of a choledochal cyst type I and biliary reconstruction in a 14-year-old girl. No intraoperative complications or technical problems were encountered. An intraabdominal collection occurred and was successfully treated with continuous percutaneous drainage. At one-year follow-up, she is doing well without evidence of recurrent cholangitis. PMID:20937150

    A detailed understanding of renal surgical anatomy is necessary to optimize preoperative planning and operative technique and provide a basis for improved outcomes. To evaluate the literature regarding pertinent surgical anatomy of the kidney and related structures, nephrometry scoring systems, and current surgical strategies for partial nephrectomy (PN). A literature review was conducted. Surgical renal anatomy fundamentally impacts PN surgery. The renal artery divides into anterior and posterior divisions, from which approximately five segmental terminal arteries originate. The renal veins are not terminal. Variations in the vascular and lymphatic channels are common; thus, concurrent lymphadenectomy is not routinely indicated during PN for cT1 renal masses in the setting of clinically negative lymph nodes. Renal-protocol contrast-enhanced computed tomography or magnetic resonance imaging is used for standard imaging. Anatomy-based nephrometry scoring systems allow standardized academic reporting of tumor characteristics and predict PN outcomes (complications, remnant function, possibly histology). Anatomy-based novel surgical approaches may reduce ischemic time during PN; these include early unclamping, segmental clamping, tumor-specific clamping (zero ischemia), and unclamped PN. Cancer cure after PN relies on complete resection, which can be achieved by thin margins. Post-PN renal function is impacted by kidney quality, remnant quantity, and ischemia type and duration. Surgical renal anatomy underpins imaging, nephrometry scoring systems, and vascular control techniques that reduce global renal ischemia and may impact post-PN function. A contemporary ideal PN excises the tumor with a thin negative margin, delicately secures the tumor bed to maximize vascularized remnant parenchyma, and minimizes global ischemia to the renal remnant with minimal complications. In this report we review renal surgical anatomy. Renal mass imaging allows detailed delineation of the

    Full Text Available Abstract Background The effect of Total Mesorectal Excision (TME on sexual function in the male is well documented. However, there is little literature in female patients. The aim of this study was to review the pelvic autonomic nervous anatomy in the female and to perform a retrospective audit of urinary and sexual function in women following surgery for rectal cancer where TME had been performed. Urogenital dysfunction was assessed through interview and questionnaire. Method Twenty-three questionnaires, eighteen returned, were sent to women with a mean age 65.5 yrs (range 34–86. All had undergone total mesorectal excision for rectal cancer between 1998–2001. Mean follow-up was 18.8 months (range 3–35. Results Preoperatively 5/18 (28% were sexually active, 3/18 (17% of patients described urinary frequency and nocturia and 7/18 (39% described symptoms of stress incontinence prior to surgery. Postoperatively all sexually active patients remained active although all described some discomfort with penetration. Two of the patients sexually active described reduced libido secondary to the stoma. Postoperative urinary symptoms developed with 59% reporting the development of nocturia, 18% developed stress incontinence and one patient required a permanent catheter. Of those with symptoms, 80% persisted longer than three months from surgery. Symptoms were predominant in those patients with low rectal cancers, particularly those undergoing abdomino-perineal excision and in those who had previously undergone abdominal hysterectomy. Conclusion The treatment of rectal cancer involves surgery to the pelvic floor. Despite nerve preservation this is associated with the development of worsening nocturia and stress incontinence. This is most marked in those patients who had previously undergone a hysterectomy. Further studies are warranted to assess the interaction with previous gynaecological surgery.

  9. Per-anal excision of large, rectal, villous adenomas. (United States)

    Featherstone, J M; Grabham, J A; Fozard, J B


    Considering the malignant potential of villous adenoma of the rectum, complete resection at the first intervention is desirable and yet many series suggest that a high recurrence rate must be expected. The experience of one colorectal surgeon in the management of this condition is described. Between 1993 and 2000, 50 patients underwent per-anal resection of villous adenoma. The procedure was conducted in the prone jackknife position unless contraindicated, with dissection performed using a diathermy blade, with particular attention to circumferential and deep margins of excision. The mean distance of the proximal margin of the tumor from the dentate line was 5.6 (range, 0.5-11) cm. The mean length of the tumor was 5.2 (range, 0.5-9) cm. Mean anesthetic time was 27 (range, 10-110) minutes, and median hospital stay was two (range, 1-14) days. There was no significant perioperative morbidity and no mortality. On histology of ten patients, there were foci of adenocarcinoma. Excision was complete histologically in 49 patients. The median follow-up was 30 (range, 6-91) months. The patient with incomplete excision developed a probable recurrence after six months, which was ablated with diathermy (residual tumor rate, 2.1 percent). Two patients have subsequently developed villous adenoma at different sites within the rectum (metachronous tumor rate, 4.3 percent). Many series of this procedure report recurrence in up to 36 percent and significant complication in up to 19 percent of patients. Transanal endoscopic microsurgery has achieved recurrence rates of 2.8 percent and low complication rates but for economic reasons has failed to find a widespread role. This article demonstrates that large, villous tumors of the low and mid rectum can be simply and effectively treated by per-anal resection with recurrence rates equivalent to transanal endoscopic microsurgery.

  10. Ultrasound diagnosis and laparoscopic excision of an interstitial ectopic pregnancy. (United States)

    Wood, C; Hurley, V


    Interstitial tubal pregnancy occurs in about 5% of ectopic tubal pregnancies and is associated with an increased risk of severe haemorrhage (1). Diagnosis prior to rupture of the pregnancy into the peritoneal cavity is very important to avoid haemorrhage. Its presence has been considered to be a contraindication to laparoscopic surgery (2), although most ectopic pregnancies can be managed laparoscopically by an experienced endoscopist. We report the diagnosis of an interstitial pregnancy by ultrasound before rupture and treatment by laparoscopic excision of the pregnancy.

    BACKGROUND: Laparoscopic total mesorectal excision (LaTME) has improved short-term outcomes of rectal cancer surgery with comparable oncological results to open approach. LaTME can be difficult in the lower most part of the rectum, leading potentially to higher rates of complications, conversion...... of conversion, operating time and hospital stay. RESULTS: In total, 50 patients were included (TaTME = 25, LaTME = 25). The groups were comparative in demographic data and tumour characteristics. Circumferential resection margin was positive in one patient in TaTME group versus four patients in LaTME group (P=0...

  12. Excision arthroplasty for management of coxofemoral luxation in pet birds. (United States)

    MacCoy, D M


    Coxofemoral luxation, although not a common injury, can cause considerable pelvic limb dysfunction in pet birds. Luxation usually is craniodorsal, as it is in dogs. Previously recommended treatments have not always been effective in managing the injury. Sequelae can include dorsolateral deviation of the pelvic limb, with loss of function and bumblefoot in the nonluxated limb, owing to abnormal weight-bearing. Excision arthroplasty combined with a muscular sling constructed from a segment of the iliofibularis muscle was used to treat coxofemoral luxation in a hyacinth macaw, a moluccan cockatoo, and an African gray parrot. The outcome was excellent in 2 of the 3 birds.

    We study the numerical propagation of waves through future null infinity in a conformally compactified spacetime. We introduce an artificial cosmological constant, which allows us some control over the causal structure near null infinity. We exploit this freedom to ensure that all light cones are tilted outward in a region near null infinity, which allows us to impose excision-style boundary conditions in our finite-difference code. In this preliminary study we consider electromagnetic waves propagating in a static, conformally compactified spacetime

  14. Base excision repair mechanisms and relevance to cancer susceptibility

    International Nuclear Information System (INIS)

    Dogliotti, E.; Wilson, S.H.


    The base excision repair (BER) pathway is considered the predominant DNA repair system in mammalian cells for eliminating small DNA lesions generated at DNA bases either exogenously by environmental agents or endogenously by normal cellular metabolic processes (e.g. production of oxyradical species, alkylating agents, etc). The main goal of this project is the understanding of the involvement of BER in genome stability and in particular in sporadic cancer development associated with inflammation such as gastric cancer (GC). A major risk factor of GC is the infection by Helicobacter pylori, which causes oxidative stress. Oxidative DNA damage is mainly repaired by BER

  15. Arthroscopic Excision of a Huge Ununited Ossicle Due to Osgood-Schlatter Disease in an Adult Patient

    Directory of Open Access Journals (Sweden)

    LI Zhi-yao


    Full Text Available Introduction: Surgical excision of the ununited ossicles has been suggested for unresolved sequelae of Osgood-Schlatter disease in adults resistant to conservative measures. We report a case where arthroscopy was used to excise the ossicles. A bird eye view from the superolateral portal was helpful in the arthroscopic procedure for excision of the deep low lesion. Case Report: A 32-year-old, male driver had anterior knee pain during walking and sports activity that had been treated conservatively for 3 months. On physical examination, there was a prominent tibial tubercle, but without palpable pain. There was obvious pain when the knee was approaching full extension. On image, a huge ununited ossicle was seen behind the patellar tendon, intruding into the joint space, and there was another two small ununited ossicles beneath the bow-shaped patellar tendon. Arthroscopy was performed through a three portals technique, and a bird eye view was achieved from the superolateral portal. The ossicles were separated from the surrounding soft tissue with a motorized shaver. The small ununited ossicles were removed by use of a grasper. The huge ossicle was removed by use of a motorized bur, and the contouring of the irregular surface of the tibial tubercle was performed. After 3 months, the patient returned to sports activities without any restrictions. Conclusion: This report shows that a huge ossicle can cause impingement in anterior knee compartment, and it can be easily removed arthroscopically under assistance of an additional portal. Keywords: Osgood-Schlatter disease; Knee; Arthroscopy; Superolateral portal.

  16. Mucosal tolerance disruption favors disease progression in an extraorbital lacrimal gland excision model of murine dry eye. (United States)

    Guzmán, Mauricio; Keitelman, Irene; Sabbione, Florencia; Trevani, Analía S; Giordano, Mirta N; Galletti, Jeremías G


    Dry eye is a highly prevalent immune disorder characterized by a dysfunctional tear film and a Th1/Th17 T cell response at the ocular surface. The specificity of these pathogenic effector T cells remains to be determined, but auto-reactivity is considered likely. However, we have previously shown that ocular mucosal tolerance to an exogenous antigen is disrupted in a scopolamine-induced murine dry eye model and that it is actually responsible for disease progression. Here we report comparable findings in an entirely different murine model of dry eye that involves resection of the extraorbital lacrimal glands but no systemic muscarinic receptor blockade. Upon ocular instillation of ovalbumin, a delayed breakdown in mucosal tolerance to this antigen was observed in excised but not in sham-operated mice, which was mediated by interferon γ- and interleukin 17-producing antigen-specific T cells. Consistently, antigen-specific regulatory T cells were detectable in sham-operated but not in excised mice. As for other models of ocular surface disorders, epithelial activation of the NF-κB pathway by desiccating stress was determinant in the mucosal immune outcome. Underscoring the role of mucosal tolerance disruption in dry eye pathogenesis, its prevention by a topical NF-κB inhibitor led to reduced corneal damage in excised mice. Altogether these results show that surgically originated desiccating stress also initiates an abnormal Th1/Th17 T cell response to harmless exogenous antigens that reach the ocular surface. This event might actually contribute to corneal damage and challenges the conception of dry eye as a strictly autoimmune disease. Copyright © 2016 Elsevier Ltd. All rights reserved.

  17. Micro-surgical endodontics. (United States)

    Eliyas, S; Vere, J; Ali, Z; Harris, I


    Non-surgical endodontic retreatment is the treatment of choice for endodontically treated teeth with recurrent or residual disease in the majority of cases. In some cases, surgical endodontic treatment is indicated. Successful micro-surgical endodontic treatment depends on the accuracy of diagnosis, appropriate case selection, the quality of the surgical skills, and the application of the most appropriate haemostatic agents and biomaterials. This article describes the armamentarium and technical procedures involved in performing micro-surgical endodontics to a high standard.

  18. [Application of transanal total mesorectal excision in radical surgery for rectal cancer]. (United States)

    He, Liu; Xiao, Yi


    Transanal total mesorectal excision (taTME) is a novel operative approach of the radical surgery for rectal cancer, and has been a hot topic in colorectal surgery for years. TaTME aims to solve some problems from previous TME, such as exposure of peripheral mid-lower rectal space, judge of distal cutting margin, and to carry out completely minimal invasive operation. According to the degree of completion of different surgical approach, taTME can be divided into laparoscopic assisted taTME (hybrid taTME) and fully through the anal approach to complete the taTME (pure taTME). At present, the anal operation equipment suitable for taTME is divided into two types: transnasal endoscopic microsurgical platform (TEM-TME) and transnasal minimally invasive surgical platform (TAMIS-TME). Until now, there is no consensus on the indications of taTME. For the treatment of some special circumstances resulting in surgical difficulties, such as low rectal cancer, male, obesity, patients with narrow pelvis, tumor depth of invasion to the surrounding tissue, tumor diameter >4 cm, tissue distortions by neoadjuvant therapy and refractory benign disease, taTME has potential advantages. As for contraindications, obstructive rectal cancer, emergency surgery and advanced tumors should currently be regarded as contraindications of taTME. It was reported that taTME was safe and feasible, and had a satisfactory short-term outcomes in several centers in China. The operation is characterized by good TME quality, distal margin and circumferential margins, especially in overweight patients with narrow pelvis. The surgical principle is the eternal cornerstone to ensure the radical tumor resection and the safety of patients. The laparoscopic technique is widely used in China and surgeons are going to be skilled with laparoscopic surgeries for low rectal cancers. This situation postpones the development of taTME. It is challenging and disputing to advocate taTME to replace transabdominal

    Arezzo, Alberto; Mintz, Yoav; Allaix, Marco Ettore; Arolfo, Simone; Bonino, Marco; Gerboni, Giada; Brancadoro, Margherita; Cianchetti, Matteo; Menciassi, Arianna; Wurdemann, Helge; Noh, Yohan; Althoefer, Kaspar; Fras, Jan; Glowka, Jakob; Nawrat, Zbigniew; Cassidy, Gavin; Walker, Rich; Morino, Mario


    Sponsored by the European Commission, the FP7 STIFF-FLOP project aimed at developing a STIFFness controllable Flexible and Learn-able manipulator for surgical operations, in order to overcome the current limitations of rigid-link robotic technology. Herein, we describe the first cadaveric series of total mesorectal excision (TME) using a soft and flexible robotic arm for optic vision in a cadaver model. TME assisted by the STIFF-FLOP robotic optics was successfully performed in two embalmed male human cadavers. The soft and flexible optic prototype consisted of two modules, each measuring 60 mm in length and 14.3 mm in maximum outer diameter. The robot was attached to a rigid shaft connected to an anthropomorphic manipulator robot arm with six degrees of freedom. The controller device was equipped with two joysticks. The cadavers (BMI 25 and 28 kg/m 2 ) were prepared according to the Thiel embalming method. The procedure was performed using three standard laparoscopic instruments for traction and dissection, with the aid of a 30° rigid optics in the rear for documentation. Following mobilization of the left colonic flexure and division of the inferior mesenteric vessels, TME was completed down to the pelvic floor. The STIFF-FLOP robotic optic arm seemed to acquire superior angles of vision of the surgical field in the pelvis, resulting in an intact mesorectum in both cases. Completion times of the procedures were 165 and 145 min, respectively. No intraoperative complications occurred. No technical failures were registered. The STIFF-FLOP soft and flexible robotic optic arm proved effective in assisting a laparoscopic TME in human cadavers, with a superior field of vision compared to the standard laparoscopic vision, especially low in the pelvis. The introduction of soft and flexible robotic devices may aid in overcoming the technical challenges of difficult laparoscopic procedures based on standard rigid instruments.

    Rominger, Marga B; Steinmetz, Carolin; Westerman, Ronny; Ramaswamy, Annette; Albert, Ute-Susann


    In this study we evaluated mammographic, histological and immunohistochemical findings for microcalcification-associated breast cancer with regards to breast-conserving therapy, recurrence and survival rate. We retrospectively analyzed 99 consecutive, non-palpable and microcalcification-associated breast cancers (94 women) that were treated surgically between January 2002 and December 2003 at a national academic breast cancer center. Calcifications were classified according to the Breast Imaging Reporting and Data System (BI-RADS). Descriptors, surgical outcome and histological findings were assessed. Recurrences and survival rates were evaluated based on medical records, standardized patient questionnaires and/or contacting the physician. 42 of the 99 lesions (42.4%) were invasive carcinomas, 57 (57.6%) were pure ductal carcinoma in situ (DCIS). 6 out of 99 (6.1%) lesions were triple negative, and 29 (29.3%) were HER2/neu positive. Successful first excision rate was 76/99 lesions (76.8%). Breast conservation was achieved in 73.7% (73/99). 10 women showed local recurrences without negatively impacting survival. The recurrences included round/punctate, amorphous, fine pleomorphic, and fine linear or fine-linear branching descriptors. The breast cancer-specific long-term survival rate was 91/94 (96.8%) for a mean follow-up of 81.4 months. The 3 patients who died due to breast carcinoma showed fine pleomorphic calcifications, and had nodal-positive invasive carcinoma at diagnosis. Microcalcification-associated breast cancers are frequently treated with breast-conserving therapy. Continuous clinical and mammographic follow-up is recommended for all descriptors.

  1. [Associated vessel heteromorphosis in laparoscopic complete mesocolic excision and solutions to intraoperative hemorrhage]. (United States)

    Jiao, Yurong; He, Jinjie; Li, Jun; Xu, Dong; Ding, Kefeng


    Vessel identification and dissection are the key processes of laparoscopic complete mesocolic excision (CME). Vascular injury will lead to complications such as prolonged operative time, intraoperative hemorrhage and ischemia of anastomotic stoma. Superior mesenteric artery (SMA), superior mesenteric vein(SMV), gastrointestinal trunk, left colic artery(LCA), sigmoid artery and marginal vessels in the mesentery have been found with possibility of heteromorphosis, which requires better operative techniques. Surgeons should recognize those vessel heteromorphosis carefully during operations and adjust strategies to avoid intraoperative hemorrhage. Preoperative abdominal computed tomography angiography(CTA) with three-dimensional reconstruction can find vessel heteromorphosis within surgical area before operation. Adequate dissection of veins instead of violent separation will decrease intraoperative bleeding and be helpful for dealing with the potential hemorrhage. When intraoperative hemorrhage occurs, surgeons need to control the bleeding by simple compression or vascular clips depending on the different situations. When the bleeding can not be stopped by laparoscopic operation, surgeons should turn to open surgery without hesitation.

    Robert, A-L; Nicolas, F; Lavoué, V; Henno, S; Mesbah, H; Porée, P; Levêque, J


    To assess whether there is a correlation between the length of a conization specimen and the length of the cervix measured by vaginal ultrasonography after the operation Prospective observational study including patients less than 45 years with measurement of cervical length before and the day of the conization, and measuring the histological length of the specimen. Among the 40 patients enrolled, the average ultrasound measurements before conization was 26.9 mm (± 4.9 mm) against 18.1mm (± 4.4mm) after conization with a mean difference of 8.8mm (± 2.4mm) (difference statistically significant Pcervix length remove by loop-excision in our series is 33% (± 8.5%). A good correlation between the measurements of the specimen and the cervical ultrasound length before and after conization was found, as a significant reduction in cervical length after conization. The precise length of the specimen should be known in case of pregnancy and the prevention of prematurity due to conization rests on selected indications and efficient surgical technique.

  3. Direct simultaneous measurement of intraglottal geometry and velocity fields in excised larynges. (United States)

    Khosla, Sid; Oren, Liran; Ying, Jun; Gutmark, Ephraim


    Current theories regarding the mechanisms of phonation are based on assumptions about the aerodynamics between the vocal folds during the closing phase of vocal fold vibration. However, many of these fundamental assumptions have never been validated in a tissue model. In this study, the main objective was to determine the aerodynamics (velocity fields) and the geometry of the medial surface of the vocal folds during the closing phase of vibration. The main hypothesis is that intraglottal vortices are produced during vocal fold closing when the glottal duct has a divergent shape and that these vortices are associated with negative pressures. Experiments using seven excised canine larynges. The particle imaging velocimetry (PIV) method was used to determine the velocity fields at low, mid-, and high subglottal pressures for each larynx. Modifications were made to previously described PIV methodology to allow the measurement of both the intraglottal velocity fields and the position of the medial aspects of the vocal fold. At relatively low subglottal pressures, little to no intraglottal vortices were seen. At mid- and high subglottal pressures, the flow separation vortices occurred and produced maximum negative pressures, relative to atmospheric, of -2.6 to -14.6 cm H2 O. Possible physiological and surgical implications are discussed. Intraglottal vortices produce significant negative pressures at mid- and high subglottal pressures. These vortices may be important in increasing maximum flow declination rate and acoustic intensity. N/A. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    Perniciaro, G; Franchelli, S; Rainero, M L; Santi, P L


    The general increase in the incidence of malignant melanoma has caused a more massive presence at the level of special sites such as the face, posing problems of the reconstruction from a cosmetic point of view. The widespread move away from large margins of exercise (3-5 cm) towards margins of approximately 1 cm surrounding the lesion, together with the improved prognosis for this pathology on the face compared to other sites, calls for greater attention to be paid to the reconstructive techniques used. Since surgery is the only solution "quoad vitam" for the patient, it is now preferable to attempt to offer the patient both a complete exeresis of the neoplasia and a satisfactory cosmetic result. In this study the authors report four cases involving the excision of malignant melanoma in the cervico-cephalic district and their consequent reconstruction using special surgical techniques.

  6. Surgical handicraft: teaching and learning surgical skills. (United States)

    Barnes, R W


    Surgeons choose their profession with a strong desire to excel at manual therapeutic skills. Although we mime our mentors, we have often received the torch of technique in the absence of a systematic program to optimally develop our manual dexterity. The operating room is the ultimate arena to refine one's technical ability, but a surgical skills laboratory should assume increasing importance in introducing the trainee to the many nuances of the fine manual motor skills necessary for optimal surgical technique. Surgical educators should address the science of surgical handicraft in a manner similar to the science of preoperative and postoperative surgical principles that have been espoused over the past 40 years. Although it has been euphemistically said that "you can teach a monkey to operate," few of us have broken the process down into the basic elements to accomplish such a goal. In view of the increasing complexity of operations and equipment, the constraints on animal laboratories and teaching caseloads, and the mounting economic and medico-legal pressures, the development of optimal surgical skills should be a major objective of every surgical training program. By developing novel programs and scientifically evaluating the results of such endeavors, surgical faculties may find increased academic rewards for being a good teacher.

  7. Excision repair of ultraviolet damage in mammalian cells: evidence for two steps in the excision of pyrimidine dimers

    International Nuclear Information System (INIS)

    Williams, J.I.; Cleaver, J.E.


    The incidence of pyrimidine dimer formation and the kinetics of DNA repair in African green monkey kidney CV-1 cells after ultraviolet (uv) irradiation were studied by measuring survival, T4 endonuclease V-sensitive sites, the fraction of pyrimidine dimers in acid-insoluble DNA as determined by thin layer chromatography (TLC), and repair replication. CV-1 cells exhibit a survival curve with extrapolation number n = 7.8 and D 0 = 2.5 J/m 2 . Pyrimidine dimers were lost from acid-insoluble DNA more slowly than endonuclease-sensitive sites were lost from or new bases were incorporated into high molecular weight DNA during the course of repair. Growth of CV-1 cultures in [ 3 H]thymidine or x irradiation (2 or 10 krads) 24 h before uv irradiation had no effect on repair replication induced by 25 J/m 2 of uv. These results suggest that pyrimidine dimer excision measurements by TLC are probably unaffected by radiation from high levels of incorporated radionuclides. The endonuclease-sensitive site and TLC measurements can be reconciled by the assumption that pyrimidine dimers are excised from high molecular weight DNA in acid-insoluble oligonucleotides that are slowly degraded to acid-soluble fragments

  8. State-Specific Liquor Excise Taxes and Retail Prices in Eight U.S. States, 2012


    Siegel, Michael; Grundman, Jody; DeJong, William; Naimi, Timothy S.; King, Charles; Albers, Alison B.; Williams, Rebecca S.; Jernigan, David H.


    We investigated the relationship between state excise taxes and liquor prices in eight states, using 2012 data for 45 brands. We made 6,042 price observations among 177 liquor stores with online prices. Using a hierarchical model, we examined the relationship between excise taxes and product prices. State excise taxes were significantly related to liquor prices, with an estimated pass-through rate of 0.93. The proportion of price accounted for by excise taxes averaged 7.0%. We find that excis...

    To examine perioperative mortality, long-term survival, causes of death, and prognostic factors for dogs and cats undergoing surgical excision of thymic epithelial tumors (TETs). Multi-institutional case series. Eighty dogs and 32 cats. Follow-up information was obtained for dogs and cats that underwent surgical excision of a TET between 2001 and 2012. Perioperative mortality was 20% in dogs and 22% in cats. No independent risk factors for perioperative mortality were identified. The estimated median survival time for all dogs was 1.69 years (95% CI 0.56-4.32) and the 1- and 4-year survival rates were 55% (95% CI 44-67) and 44% (95% CI 32-56). The estimated median survival time for all cats was 3.71 years (95% CI 0.56-unestimatable) and the 1- and 4-year survival rates were 70% (95% CI 53-87) and 47% (95% CI 0-100). Of animals that survived to discharge, 42% of dogs and 20% of cats eventually died of TET-related causes. The presence of paraneoplastic syndromes (hazard ratio [HR] 5.78, 95% CI 1.64-20.45, P = .007) or incomplete histologic margins (HR 6.09, 95% CI 1.50-24.72, P = .01) were independently associated with decreased survival in dogs. No significant predictors of survival were identified in cats. Conclusions regarding the effect of chemotherapy or radiation therapy could not be made. While there is substantial risk of perioperative death in dogs and cats undergoing surgery for TETs, many animals that survive to discharge have prolonged survival. Survival is significantly decreased in dogs with paraneoplastic syndromes or incomplete histologic margins. © Copyright 2014 by The American College of Veterinary Surgeons.

    The American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) classification was developed to risk stratify breast lesions and guide surgical management based on imaging. Previous studies validating BI-RADS for US do not include pediatric patients. Most pediatric breast masses present as palpable lesions and frequently undergo ultrasound, which is often accompanied with a BI-RADS classification. Our study aimed to correlate BI-RADS with pathology findings to assess applicability of the classification system to pediatric patients. We performed a retrospective review of all patients who underwent excision of a breast mass at a single center from July 2010 to November 2013. We identified all patients who underwent preoperative ultrasound with BI-RADS classification. Demographic data, imaging results, and surgical pathology were analyzed and correlated. A total of 119 palpable masses were excised from 105 pediatric patients during the study period. Of 119 masses, 81 had preoperative ultrasound, and BI-RADS categories were given to 51 masses. Of these 51, all patients were female and the average age was 15.9 years. BI-RADS 4 was given to 25 of 51 masses (49%), and 100% of these lesions had benign pathology, the most common being fibroadenoma. Treatment algorithm based on BI-RADS classification may not be valid in pediatric patients. In this study, all patients with a BI-RADS 4 lesion had benign pathology. BI-RADS classification may overstate the risk of malignancy or need for biopsy in this population. Further validation of BI-RADS classification with large scale studies is needed in pediatric and adolescent patients. Copyright © 2015 Elsevier Inc. All rights reserved.

  12. Trends in the Surgical Correction of Gynecomastia (United States)

    Brown, Rodger H.; Chang, Daniel K.; Siy, Richard; Friedman, Jeffrey


    Gynecomastia refers to the enlargement of the male breast due to a proliferation of ductal, stromal, and/or fatty tissue. Although it is a common condition affecting up to 65% of men, not all cases require surgical intervention. Contemporary surgical techniques in the treatment of gynecomastia have become increasingly less invasive with the advent of liposuction and its variants, including power-assisted and ultrasound-assisted liposuction. These techniques, however, have been largely limited in their inability to address significant skin excess and ptosis. For mild to moderate gynecomastia, newer techniques using arthroscopic morcellation and endoscopic techniques promise to address the fibrous component, while minimizing scar burden by utilizing liposuction incisions. Nevertheless, direct excision through periareolar incisions remains a mainstay in treatment algorithms for its simplicity and avoidance of additional instrumentation. This is particularly true for more severe cases of gynecomastia requiring skin resection. In the most severe cases with significant skin redundancy and ptosis, breast amputation with free nipple grafting remains an effective option. Surgical treatment should be individualized to each patient, combining techniques to provide adequate resection and optimize aesthetic results. PMID:26528088

  13. Cervical chordoma managed with multidisciplinary surgical approach. (United States)

    Ahsan, Farhan; Inglis, Tom; Allison, Robert; Inglis, Grahame S


    This paper describes the interdisciplinary management of a 62-year-old man who presented with a cervical chordoma of C2/3. This is a rare neoplasm of the axial skeleton which is usually treated surgically. This is technically challenging due to the surrounding anatomy and requirement for wide exposure. A number of surgical approaches have been described to access the clivus and upper cervical spine. This case involved both the Orthopaedic and Otolaryngology Head and Neck Surgery departments. Trotter's surgical technique was used to gain access for excision of the cervical chordoma and there was collaboration with an Orthopaedic Biotechnology Company in which a bio-model of the spine was created and a corpectomy cage specific to the patient developed. This approach allowed excellent visualisation of the tumour and the unique cage and plate achieved immediate stability and long term fusion. An interdisciplinary approach should be used in the management of upper cervical chordomas to facilitate tumour resection and reduce the potential for recurrence. © 2010 The Authors.

  17. Laser excision of a mucocele: A case report

    Directory of Open Access Journals (Sweden)

    Rajashree Ganguly


    Full Text Available A mucous cyst (mucocele, mucous retention cyst, ranula, and epulis is usually a painless, thin sac on the inner surface of the lips. It contains clear fluid. It is painless but can be bothersome. The cyst is thought to be caused due to sucking of the lip membranes between the teeth. A mucous cyst is common and harmless. However, if left untreated, it can organize and form a permanent bump on the inner surface of the lip. A mucous cyst is called ranula when it occurs on the floor of the mouth and epulis when it occurs on the gums. The sac may also be formed around the jewellery (piercings that has been inserted into the lips or the tongue. This article highlights the use of lasers in the treatment of the excision of mucocele.

  18. [A case of giant thyroid tumor locally excised]. (United States)

    Enomoto, Katsuhisa; Sakurai, Kenichi


    A case was a 59-year-old woman. We noted a cervical swelling more than 30 years ago but we neglected it. We also confirmed hypothyroidism and the patient's progress was satisfactory with an internal treatment. However, the cervical swelling gradually became enlarged, we operated on her. Cervical echography findings revealed whole thyroid gland swells. Cervical CT also showed a thyroid swelling which pressed into the trachea. Total thyroidectomy was performed. Histopathological laboratory findings were of nodular hyperplasia with chronic thyroiditis. The thyroid tumor weighted 240 g, and the size was about 10 × 10 × 3.8 cm. We observed a postoperative temporary hypothyroidism. In case that the thyroid function was stable and a low possibility of malignancy in the laboratory findings, we should follow the disease progress carefully. Furthermore, it is important that a local excision has to be carefully performed because of a gradual enlargement of the disease accompanied with accessory symptom as well as a cosmetic attractiveness.

  19. Quantifying Long-term Retention of Excised Fat Grafts

    DEFF Research Database (Denmark)

    Herly, Mikkel; Ørholt, Mathias; Glovinski, Peter V.


    Background: Predicting the degree of fat graft retention is essential whenplanning reconstruction or augmentation with free fat grafting. Most surgeonsobserve volume loss over time after fat grafting; however, the portion lost toresorption after surgery is still poorly defined, and the time...... to reach steadystate is unknown. Methods: The authors compiled a retrospective, longitudinal cohort of patientswith vestibular schwannoma who had undergone ablative surgery and reconstructionwith excised fat between the years 2006 and 2015. Fat volume retentionwas quantified by computed tomography....... The average baseline graft volumewas 18.1 ± 4.8 ml. The average time to reach steady state was 806 days aftertransplantation. By this time, the average fat graft retention was 50.6 percent(95 percent CI, 46.4 to 54.7 percent). No statistically significant association wasfound between baseline graft volume...

  20. Chromatin Dynamics during Nucleotide Excision Repair: Histones on the Move (United States)

    Adam, Salomé; Polo, Sophie E.


    It has been a long-standing question how DNA damage repair proceeds in a nuclear environment where DNA is packaged into chromatin. Several decades of analysis combining in vitro and in vivo studies in various model organisms ranging from yeast to human have markedly increased our understanding of the mechanisms underlying chromatin disorganization upon damage detection and re-assembly after repair. Here, we review the methods that have been developed over the years to delineate chromatin alterations in response to DNA damage by focusing on the well-characterized Nucleotide Excision Repair (NER) pathway. We also highlight how these methods have provided key mechanistic insight into histone dynamics coupled to repair in mammals, raising new issues about the maintenance of chromatin integrity. In particular, we discuss how NER factors and central players in chromatin dynamics such as histone modifiers, nucleosome remodeling factors, and histone chaperones function to mobilize histones during repair.

  1. [Meta-analysis of extralevator abdominoperineal excision for rectal cancer]. (United States)

    Chen, Yilin; Chi, Pan


    To evaluate the efficacy of extralevator abdominoperineal excision (ELAPE) of rectal cancer. PubMed, Cochrane Library and Embase database were searched for clinical studies comparing the ELAPE and abdominoperineal excision (APE) for rectal cancer between 2007 and 2016. Two reviewers independently screened the articles and extracted the data. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the observational studies and the score more than 5 points was the inclusion criteria. Cochrane Handbook for Systematic Reviews of Interventions v5.1.0 was used to evaluate the quality of the randomized controlled trials (RCT). Intra-operative perforation rate, circumferential resection margin (CRM) involvement, local recurrence rate, perineal wound complications were brought into meta-analysis by Review Manager 5.3 software. A total of 556 articles were retrieved and 12 articles were enrolled finally, including 11 observational studies and 1 RCT study. All the 12 articles were high quality (scores of all observational studies were more than 11 points, RCT study accorded with 6 criteria of the quality evaluation). A total of 3 788 patients were enrolled, including 2 141 cases of ELAPE and 1 647 cases of APE. Meta-analysis revealed that intra-operative perforation rate of ELAPE was lower than APE (RR=0.52, 95%CI:0.34-0.79, P=0.002). There were no significant differences between two groups in CRM involvement (RR=0.72, 95%CI:0.49-1.07, P=0.10), local recurrence rate (OR=0.55, 95%CI:0.24-1.29, P=0.17) and perineal wound complications (RR=0.94, 95%CI:0.58-1.53, P=0.800). Compared with APE, ELAPE reduces the intra-operative perforation rate, and does not increase the perineal wound complications, but it has no advantages in decreasing the CRM involvement and local recurrence rate.

  2. Framing the policy debate over spirits excise tax in Poland. (United States)

    Zatoński, Mateusz; Hawkins, Benjamin; McKee, Martin


    Industry lobbying remains an obstacle to effective health-oriented alcohol policy. In 2013, an increase in excise tax on spirits was announced by the Polish government. This article presents a qualitative analysis of the public debate that ensued on the potential economic, health and social effects of the policy. It focuses on how competing groups, including industry actors, framed their position and sought to dominate the debate. Online archives of five Polish national newspapers, two spirits trade associations, and parliamentary and ministerial archives were searched. A thematic content analysis of the identified sources was conducted. The overall findings were compared with existing research on the framing of the Minimum Unit Pricing (MUP) debate in the UK. A total of 155 sources were analysed. Two main frames were identified: health, and economic The spirits industry successfully promoted the economic frame in their own publications and in the media. The debate was dominated by arguments about potential growth of the grey market and losses in tax revenue that might result from the excise tax increase. The framing of the debate in Poland differed from the framing of the MUP debate in the United Kingdom. The Polish public health community was unsuccessful in making health considerations a significant element of the alcohol policy debate. The strategies pursued by UK health advocates offer lessons for how to make a more substantial impact on media coverage and promote health-oriented legislation. © The Author 2016.

  3. Reverse-hybrid robotic mesorectal excision for rectal cancer. (United States)

    Park, In Ja; You, Y Nancy; Schlette, Erika; Nguyen, Sa; Skibber, John M; Rodriguez-Bigas, Miguel A; Chang, George J


    The robotic system offers potential technical advantages over laparoscopy for total mesorectal excision with radical lymphadenectomy for rectal cancer. However, the requirement for fixed docking limits its utility when the working volume is large or patient repositioning is required. The purpose of this study was to evaluate short-term outcomes associated with a novel setup to perform total mesorectal excision and radical lymphadenectomy for rectal cancer by the use of a "reverse" hybrid robotic-laparoscopic approach. This is a prospective consecutive cohort observational study of patients who underwent robotic rectal cancer resection from January 2009 to March 2011. During the study period, a technique of reverse-hybrid robotic-laparoscopic rectal resection with radical lymphadenectomy was developed. This technique involves reversal of the operative sequence with lymphovascular and rectal dissection to precede proximal colonic mobilization. This technique evolved from a conventional-hybrid resection with laparoscopic vascular control, colonic mobilization, and robotic pelvic dissection. Perioperative and short-term oncologic outcomes were analyzed. Thirty patients underwent reverse-hybrid resection. Median tumor location was 5 cm (interquartile range 3-9) from the anal verge. Median BMI was 27.6 (interquartile range 25.0-32.1 kg/m). Twenty (66.7%) received neoadjuvant chemoradiation. There were no conversions. Median blood loss was 100 mL (interquartile range 75-200). Total operation time was a median 369 (interquartile range 306-410) minutes. Median docking time was 6 (interquartile range 5-8) minutes, and console time was 98 (interquartile range 88-140) minutes. Resection was R0 in all patients; no patients had an incomplete mesorectal resection. Six patients (20%) underwent extended lymph node dissection or en bloc resection. Reverse-hybrid robotic surgery for rectal cancer maximizes the therapeutic applicability of the robotic and conventional laparoscopic

  4. Determining whether excision of all fibroepithelial lesions of the breast is needed to exclude phyllodes tumor: upgrade rate of fibroepithelial lesions of the breast to phyllodes tumor. (United States)

    Van Osdol, Andrew D; Landercasper, Jeffrey; Andersen, Jeremiah J; Ellis, Richard L; Gensch, Erin M; Johnson, Jeanne M; De Maiffe, Brooke; Marcou, Kristen A; Al-Hamadani, Mohammed; Vang, Choua A


    Fibroepithelial lesions (FELs) are a common histologic finding on core needle biopsy (CNB) of the breast. Fibroepithelial lesions include fibroadenoma and phyllodes tumor, which can be difficult to distinguish with an initial CNB. An institutional experience was reviewed from February 12, 2001, to January 4, 2007, to determine the safety of selective rather than routine excision of FELs and to determine the factors associated with upgrading diagnosis of FELs to phyllodes tumors without definitive phyllodes tumor diagnosis by CNB. Of 313 patients, 261 (83%) with FELs diagnosed by CNB received observation with long-term follow-up (mean, 8 years). Of the observed patients, 3 (1%) were diagnosed with phyllodes tumor on follow-up. Eighteen of 52 patients (35%) who received excision had an upgrade of diagnosis to phyllodes tumor. Sensitivity and specificity of the pathologist's comment of concern for phyllodes tumor on a CNB demonstrating FELs without definitive phyllodes tumor diagnosis were 82% and 93%, respectively. Our policy of selective excision of FELs without definitive phyllodes tumor diagnosis resulted in safe avoidance of many surgical procedures.

  5. Breast surgical specimen radiographs: How reliable are they?

    International Nuclear Information System (INIS)

    Britton, P.D.; Sonoda, L.I.; Yamamoto, A.K.; Koo, B.; Soh, E.; Goud, A.


    Radiography of the excised surgical specimen following wire guided localisation of impalpable breast lesions is standard surgical practice. The aims of the study were to establish the reliability of the breast specimen radiograph (SR) in determining lesion excision and to determine whether the radiographic margin correlated with the histological margin. The clinical, imaging, SR and pathological details of 106 patients with a pre-operative diagnosis of breast cancer were retrospectively reviewed. The reliability of orientation was estimated and the appearance and distance from the mammographic abnormality to each radial margin were measured and correlated with surgical histological findings. The overall accuracy of the specimen radiograph in determining whether the mammographic lesion was present was 99%. The SR could be orientated 'very reliably' or 'reliably' in 80% of patients however in only 48% of patients did the closest margin on the SR correspond with the same nearest margin at final histology. A maximum measurement of 11 mm or more from the lesion to the specimen edge was associated with a 77% likelihood of having a clear final histological margin (taken as 5 mm or more) and if <11 mm a 58% chance of having involved final histological margins. There was however a wide overlap in the results with patients having an apparently wide SR margin but histologically involved margins and vice versa. The SR is reliable at determining whether the target lesion has been removed. The correlation of SR margin orientation and measurement with final histological measurement is however far less reliable.

  9. Carpal boss: effect of wedge excision depth on third carpometacarpal joint stability. (United States)

    Vermeulen, G M; de With, M C J; Bleys, R L A W; Schuurman, A H


    We hypothesize that carpal-metacarpal (CMC) instability after carpal boss wedge excision is not caused only by damage to the dorsal ligament but mainly depends on the depth of the bony resection. To test our hypothesis, this study analyzes the effect of wedge excisions with different depths (0, 15%, 35%, 55% of the third CMC joint) and the effect of different forces (0, 50, 100 N.m) on the stability (measured as the passive flexion) of the third CMC joint using 12 fresh-frozen human cadaver wrists. The passive flexion is defined as the increase in angular motion of the third CMC joint and represents change in stability during flexion of the joint. The results show that the mean passive flexion measured in the wedge excisions of 15% and 35% of the joint did not differ from that of neutral controls. Joints analyzed after a 55% wedge excision showed a significant increase in angular motion (increased passive flexion). This relates to the 50 N.m as well as the 100 N.m loaded test position. This study shows that a wedge excision of clinically applicable depth of 35% does not create instability during flexion of the third CMC joint when loaded with physiologically relevant forces. Yet an extended and hardly clinically relevant 55% wedge excision results in a change in stability of the joint. To prevent instability when performing a wedge excision for symptomatic carpal boss, care must be taken to avoid excisions that exceed 35% of the third CMC joint.

  10. Recent trends in tobacco sales, excise revenues, and affordability in the former USSR countries

    Directory of Open Access Journals (Sweden)

    Konstantin Krasovsky


    Cigarette sales in the region decreased in 2008-2015 and the key factor for the decline was the reduction of tobacco affordability. Only the substantial increase in excise rates can guarantee both revenue growth and the reduction of tobacco consumption. To reduce tobacco consumption, excise rates should be increased annually taking into account inflation and income growth.

  11. Posterior Endoscopic Excision of Os Trigonum in Professional National Ballet Dancers. (United States)

    Ballal, Moez S; Roche, Andy; Brodrick, Anna; Williams, R Lloyd; Calder, James D F


    Previous studies have compared the outcomes after open and endoscopic excision of an os trigonum in patients of mixed professions. No studies have compared the differences in outcomes between the 2 procedures in elite ballet dancers. From October 2005 to February 2010, 35 professional ballet dancers underwent excision of a symptomatic os trigonum of the ankle after a failed period of nonoperative treatment. Of the 35 patients, 13 (37.1%) underwent endoscopic excision and 22 (62.9%) open excision. We compared the outcomes, complications, and time to return to dancing. The open excision group experienced a significantly greater incidence of flexor hallucis longus tendon decompression compared with the endoscopic group. The endoscopic release group returned to full dance earlier at a mean of 9.8 (range 6.5 to 16.1) weeks and those undergoing open excision returned to full dance at a mean of 14.9 (range 9 to 20) weeks (p = .001). No major complications developed in either group, such as deep infection or nerve or vessel injury. We have concluded that both techniques are safe and effective in the treatment of symptomatic os trigonum in professional ballet dancers. Endoscopic excision of the os trigonum offers a more rapid return to full dance compared with open excision. Copyright © 2016 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.

  13. Parenteral corticosteroids followed by early surgical resection of large amblyogenic eyelid hemangiomas in infants

    Directory of Open Access Journals (Sweden)

    El Essawy R


    Full Text Available Rania El Essawy,1 Rasha Essameldin Galal21Department of Ophthalmology, 2Department of Pediatrics, Faculty of Medicine, Cairo University, Cairo, EgyptBackground: The purpose of this study was to evaluate the results and complications of early surgical resection of large amblyogenic subdermal eyelid hemangiomas in infants after prior short-term parenteral administration of corticosteroids.Methods: Sixteen infants were given dexamethasone 2 mg/kg/day in two divided doses for three consecutive days prior to scheduled surgical excision of large eyelid hemangiomas. The lesions were accessed via an upper eyelid crease, subeyebrow incision, or a lower eyelid subciliary incision.Results: In all cases, surgical excision of the entire lesion was possible with no significant intraoperative or postoperative complications. The levator muscle/aponeurosis complex was involved in 31.25% of cases and was managed by reinsertion or repositioning without resection. A satisfactory lid position and contour with immediate clearing of the visual axis was achieved in all but one case (93.8%.Conclusion: Parenteral corticosteroids helped in reducing volume and blood flow from the hemangiomas, allowing for very early total excision of large subdermal infantile hemangiomas without significant intraoperative hemorrhage. This resulted in immediate elimination of any reason for occlusion amblyopia. Long-term follow-up of visual development in these patients would help to demonstrate the effectiveness of this strategy compared with more conservative measures.Keywords: large eyelid hemangiomas, early surgical resection, parenteral corticosteroids

  14. Novel modified surgical treatment of auricular pseudocyst using plastic sheet compression. (United States)

    Shan, Yamin; Xu, Jing; Cai, Changping; Wang, Shili; Zhang, Hao


    To introduce a novel modified surgical procedure of excision of anterior cartilage of the pseudocyst along with plastic sheet compression for the treatment of auricular pseudocyst and ascertain the effect of the surgical modality of this disease. A retrospective study. Medical college hospital. Eighty-seven auricular pseudocyst patients were subjected to excision of the anterior cartilage of the pseudocyst followed by plastic sheet compression from July 2006 to September 2013. The effects of the operation were evaluated. Eighty patients were males and 7 were females. The median age was 52 years old. The lesions of 86 patients were unilateral and only 1 was bilateral. The clinical features presented a hemispheric painless swelling, which was seen on the ventral side of the auricle, usually the scaphoid and triangular fossa. The average major axis of the pseudocyst was 1.7 ± 0.6 cm. The patients underwent excision of anterior cartilage of the pseudocyst along with plastic sheet compression. The average follow-up period was 51.9 ± 19.1 months. No recurrence was observed with this technique, and the appearance of the auricle was cosmetically acceptable. Our novel modified surgical procedure of excision of anterior cartilage of pseudocyst along with plastic sheet compression is an effective surgical management for the auricular pseudocyst. The advantages of a simple technique, a short-term therapeutic period, and no recurrence made the surgical procedure worth recommending as the definitive treatment of auricular pseudocysts. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

    There is variation in margin policy for breast conserving therapy (BCT) in the UK and Ireland. In response to the Society of Surgical Oncology and American Society for Radiation Oncology (SSO-ASTRO) margin consensus ('no ink on tumour' for invasive and 2 mm for ductal carcinoma in situ [DCIS]) and the Association of Breast Surgery (ABS) consensus (1 mm for invasive and DCIS), we report on current margin practice and unit infrastructure in the UK and Ireland and describe how these factors impact on re-excision rates. A trainee collaborative-led multicentre prospective study was conducted in the UK and Ireland between 1st February and 31st May 2016. Data were collected on consecutive BCT patients and on local infrastructure and policies. A total of 79 sites participated in the data collection (75% screening units; average 372 cancers annually, range 70-900). For DCIS, 53.2% of units accept 1 mm and 38% accept 2-mm margins. For invasive disease 77.2% accept 1 mm and 13.9% accept 'no ink on tumour'. A total of 2858 patients underwent BCT with a mean re-excision rate of 17.2% across units (range 0-41%). The re-excision rate would be reduced to 15% if all units applied SSO-ASTRO guidelines and to 14.8% if all units followed ABS guidelines. Of those who required re-operation, 65% had disease present at margin. There continues to be large variation in margin policy and re-excision rates across units. Altering margin policies to follow either SSO-ASTRO or ABS guidelines would result in a modest reduction in the national re-excision rate. Most re-excisions are for involved margins rather than close margins. Copyright © 2017 Elsevier Ltd. All rights reserved.

  17. Complete 3rd cranial nerve dysfunction postdeflation/ excision of an encasing pituitary macroadenoma intrasellular cyst: A Case Report

    Directory of Open Access Journals (Sweden)

    Ng C. S.


    Full Text Available Central nervous system injury in particular cranial nerve palsy has been reported to be as high as 2%. Such prevalence of palsy generally attributed to surgical manipulation at the cavernous sinus, especially incurring the abducens nerve. We report the first case of acute oculomotor nerve sequel to the release of cystic fluid wrapping the nerve following a transsphenoidal excision of pituitary macroadenoma in a 57-year-old woman. She attended with the presentation of acute excruciating headache associated with partial drooping of right eye. The computed tomography and magnetic resonance imaging (MRI were consistent with pituitary apoplexy of an underlying pituitary macroadenoma. Urgent transsphenoidal hypophysectomy was done. Intra-operatively, cystic fluid was aspirated during pituitary tumour dissection. At the same time, curettage was employed to removal residual tumour after the tumour biopsy. Immediate post-operative assessment noted complete right eye ptosis, with clinical evidence of complete right third and fourth nerve palsies. MRI was repeated a week later in view of such palsy non-resolution. However, no local compression or edema noted. Observation and monitoring were opted versus surgical revision. Propitiously the aforementioned cranial nerve palsies persist for a month and subsequently subsided. In this case, we highlight the potential deleterious impact of aspirating cystic component and curettaging during pituitary surgery. Likely postulated accounts for such occurrence include sudden release of fluid pressure with resultant cystic traction on its enfolding cranial nerves and subsequent neuropraxia. We aim to invite comments that could enlighten us on this gray area.

  18. [Clinical application of pelvic floor reconstruction in extralevator abdominoperineal excision for low rectal cancer]. (United States)

    Ge, Wei; Chen, Gang; Jiang, Songsong; Wang, Hao


    To investigate the safety and clinical significance of pelvic floor reconstruction in extralevator abdominoperineal excision(ELAPE) for advanced low rectal cancer. The clinical efficacy was retrospectively analyzed in 30 patients with low rectal cancer who underwent ELAPE from January 2013 to December 2016 in Nanjing Drum Tower Hospital, the affiliated Hospital of Nanjing University Medical School. There were 21 male patients and 9 female, with an average age of 61.7 years old. We used 13*15 cm Biodesign biologic meshes(Cook, China) for the reconstruction and the procedure involved soaking in saline solution for 5 minutes and fixation of the mesh to the cut edges of the levators by non-absorbable 2-0 sutures. A perineal drain was used and was removed when drainage was minimal. Potassium permanganate was used for hip bath after removing the stitches. The surgical procedure, postoperative complications, prognosis and follow-up of all these patients were documented. The operations of all patients were completed successfully. ELAPE could remove more para cancer tissues in the distant rectum. There was no rectum perforation, and the circumferential resection margins of all specimens were proved to be negative. During the follow-up of 21 months, only 2 patients suffered incision infection and healed uneventfully after strengthening the dressing. No one developed perineal breakdown, bulge or intestinal obstruction, as well as local recurrence and pelvic floor hernia. There was also no complication related to mesh. The average hospitalization time was 10 days (9-15 days). The ELAPE could render a low occurrence of intraoperative perforations and circumferential resection margins. Reconstruction of pelvic floor with biologic meshmight lower the complication incidences associated with the perineal region.

    Full Text Available BackgroundAfter skin tumor excision on the face, extremities, or trunk, the choice of treatment for a skin defect is highly variable. Many surgeons prefer to use a local flap rather than a skin graft or free flap for small- or moderately-sized circular defects. We have used unilateral or bilateral V-Y advancement flaps, especially on the face. Here we evaluated the functional and aesthetic results of this technique.MethodsAll of the patients were pathologically diagnosed with squamous cell carcinoma (SCC, basal cell carcinoma (BCC, or malignant melanoma or premalignant lesion (Bowen's disease. Thirty-two patients underwent V-Y advancement flap repair (11 unilateral and 21 bilateral from January 2007 to June 2011. We analyzed the patients' age and satisfaction, and location and size of defect. The patients were followed up for 6 months or more.ResultsThere were 22 women and 10 men. The ages ranged from 47 to 93 years with a mean age of 66 years. The causes were SCC in 15 cases, BCC in 13 cases, malignant melanoma in 1 case, Bowen's disease in 2 cases, and another cause in 1 case. The tumor locations were the face in 28 patients, and the scalp, upper limb, and flank each in one patient. All of the flaps survived and the aesthetic results were good. Postoperative recovery was usually rapid, and no complication or tumor recurrence was observed.ConclusionsThe V-Y advancement flap is often used not only for facial circular defects but also for defects of the trunk and extremities. Its advantages are less scarring and superior aesthetic results as compared with other local flap methods, because of less scarification of adjacent tissue and because it is an easy surgical technique.

  20. Treatment of Giant Fibroadenoma in Young Women: Results after Tumor Excision without Reconstructive Surgery (United States)

    Hille-Betz, U.; Klapdor, R.; Henseler, H.; Soergel, P.; Länger, F.


    Introduction: Giant fibroadenoma (GFA) of the breast is defined as fibroadenoma larger than 5 cm, usually presenting unilaterally and manifesting as breast asymmetry or deformity of the breast. Material and Methods: A retrospective database search was done of all patients with giant fibroadenoma who underwent surgery for GFA in the breast center of Hanover Medical School between 2007 and 2014; all patients with GFA were followed up. Data were analyzed with regard to tumor and patient characteristics and esthetic outcome. Results: A total of 13 patients with symptomatic GFA underwent surgery between 2007 and 2014. Mean patient age was 21.2 years (range 14–31 years). In 8 of 13 patients the tumor had resulted in breast deformity and/or breast asymmetry. Average size of the mass was 10.2 cm (range 8.5–12 cm) and average weight was 203.6 g (range 151.2–323.5 g). Initial clinical suspicion of GFA was confirmed by ultrasound examination. Preoperative core biopsy revealed fibroadenoma in 8/13 cases, cellular fibroepithelial lesions with a differential diagnosis of benign phyllodes tumor in 3 cases and unspecific histological findings in the remaining 2 cases. Conclusion: Excision was done using an inframammary or periareolar approach without reconstructive plasty. The cosmetic results were good, as were the outcomes on follow-up. We therefore favor this surgical technique to treat giant fibroadenoma of similar size to those described above. PMID:26500369

  1. Impact of neoadjuvant treatment on total mesorectal excision for ultra-low rectal cancers

    Fan Joe FM


    Full Text Available Abstract Background This study reviewed the impact of pre-operative chemoradiotherapy or post-operative chemotherapy and/or radiotherapy on total mesorectal excision (TME for ultralow rectal cancers that required either low anterior resection with peranal coloanal anastomosis or abdomino-perineal resection (APR. We examined surgical complications, local recurrence and survival. Methods Of the 1270 patients who underwent radical resection for rectal cancer from 1994 till 2007, 180 with tumors within 4 cm with either peranal coloanal anastomosis or APR were analyzed. Patients were compared in groups that had surgery only (Group A, pre-operative chemoradiotherapy (Group B, and post-operative therapy (Group C. Results There were 115 males and the mean age was 65.43 years (range 30-89. APR was performed in 134 patients while 46 had a sphincter-preserving resection with peranal coloanal anastomosis. The mean follow-up period was 52.98 months (range: 0.57 to 178.9. There were 69, 58 and 53 patients in Groups A, B, and C, respectively. Nine patients in Group B could go on to have sphincter-saving rectal resection. The overall peri-operative complication rate was 43.4% in Group A vs. 29.3% in Group B vs. 39.6% in Group C, respectively. The local recurrence rate was significantly lower in Group B (8.6.9% vs. 21.7% in Group A vs. 33.9% in Group C p . The 5-year cancer-specific survival rates for Group A was 49.3%, Group B was 69.9% and Group C was 38.8% (p = 0.14. Conclusion Pre-operative chemoradiation in low rectal cancer is not associated with a higher incidence of peri-operative complications and its benefits may include reduction local recurrence.

  2. Proximal row carpectomy versus scaphoid excision and intercarpal arthrodesis: intraoperative assessment and procedure selection. (United States)

    Zinberg, Ephraim M; Chi, Ying


    To demonstrate the relative frequency of degenerative changes of the radiolunate and capitolunate joints in osteoarthritis of the wrist as seen by direct visualization, and to demonstrate the disparity between findings on preoperative radiographs and direct visualization. We reviewed 18 consecutive patients who underwent either a proximal row carpectomy (PRC) or a scaphoid excision and 4-corner arthrodesis (SEFCA) for symptomatic degenerative arthritis of the wrist. In each case, the articular surfaces of the radiolunate and capitolunate joints were inspected intraoperatively; based on the relative degree of degenerative changes, either a PRC or an SEFCA was performed. We compared preoperative radiographs and the predicted procedure based on them with intraoperative findings and the procedure actually performed. Of 18 wrists, 15 had more severe degenerative changes on the proximal articular surface of the lunate than on the capitate head and underwent a PRC; the remaining 3 had more severe changes on the capitate head than on the proximal surface of the lunate and underwent an SEFCA. In contrast, preoperative radiographs in 13 of the 18 cases revealed degenerative changes at the capitolunate joint and minimal or no changes at the radiolunate joint. An SEFCA was the predicted procedure in all 13, but was performed in 3. The remaining 10 underwent a PRC. Preoperative radiographs did not correlate well with intraoperative findings in the assessment of degenerative changes at the radiolunate and capitolunate joints, with changes at the radiolunate joint often underestimated. Our findings contradict the widely held contention that the radiolunate joint is consistently spared in osteoarthritis. The lunate fossa of the radius appears to be consistently spared, but not the proximal surface of the lunate. We recommend intraoperative assessment of the articular surfaces, rather than preoperative radiographs, for selection of the surgical procedure. Therapeutic IV. Copyright

  3. Results of surgical treatment of anterior abdominal wall desmoid tumours : 13 cases reviewed with literature. (United States)

    Yabanoglu, H; Karagulle, E; Aytac, H O; Caliskan, K; Canpolat, T; Koc, Z; Akdur, A C; Moray, G; Haberal, M


    We retrospectively evaluated the results of surgical treatment for anterior abdominal wall -desmoid tumours. Records for 13 patients operated on for desmoid tumours from 1997-2013 were searched for age, gender, abdominal/pelvic surgical history, pregnancy, Gardner's syndrome, pre-operative radiological examinations, tumour size, multifocality, surgical procedure, tumour presence at surgical margins, recurrence, morbidity, and mortality. Local recurrence-free survival probabilities were estimated by the Kaplan-Meier method and stratified by various clinicopathological variables. There were 11 female (84,6%) and 2 male (15,4%) patients with a median age of 36 years. Seven (53,8%) -patients had previous abdominal/pelvic surgery, five (38,5%) had a history of pregnancy, and one (7,6%) had Gardner's Syndrome. Two (15,3%) patients had multifocality on their pre-operative radiological examinations. Mean tumour -diameter was 4,6 cm (SD 3,2 cm ; range 2-12 cm). After the excision of the masses in five (38,5%) patients, synthetic materials were used to close the abdominal wall defects. Two (15,3%) patients with positive surgical margins after -surgery were re-operated. Three (23%) patients required a second surgical intervention after the mass excisions were performed. Mean follow-up time was 56,7 months. Recurrence was observed in three patients during follow-up. Increased tumour size, history of previous abdominal/pelvic surgery, and the presence of multifocality had a negative effect on local recurrence-free survival. There was no mortality during follow-up. Desmoid tumours are characterized by high recurrence, even after proper surgical excisions. Preoperative differential diagnoses of these tumours should be done and a post-operative follow-up protocol should be followed. Copyright© Acta Chirurgica Belgica.

  4. [Sequential intervention with primary excision and Limberg plastic surgery procedure for treatment of sacrococcygeal pilonidal sinus : Results of a pilot study]. (United States)

    Ardelt, M; Dittmar, Y; Scheuerlein, H; Fahrner, R; Rauchfuß, F; Settmacher, U


    The current German S3 guidelines recommend radical excision for pilonidal sinus disease. Furthermore, the Karydakis operation and the plastic surgery procedure according to Limberg are also recommended. Contrary to the S2 guidelines of 2008, these two plastic surgery procedures for coverage are recommended for the treatment of the first-time manifestation of this disease. Most studies on the classical Limberg plastic surgical procedure are comparative in nature and describe a simultaneous intervention from which patients with an abscess are excluded. The aim of this present study was to analyze the results of a sequential procedure including primary excision followed by a Limberg plastic surgery procedure for the treatment of acute abscesses and chronic pilonidal sinus disease. From July 2010 to June 2013 a total of 50 patients with pilonidal sinus disease were treated at the University Hospital Jena with an initial radical excision. In accordance with the Association of the Scientific Medical Societies in Germany (AWMF) guidelines which were valid during that time, patients were offered plastic surgery coverage for recurrence prophylaxis and in cases of recurrence a Limberg plastic surgery procedure was recommended. Of the 50 patients 22 opted for a Limberg plastic surgery procedure during the interval. The mean follow-up after the Limberg plastic surgery procedure was 20.1 months (range 2-36 months). During the follow-up period, there were no recurrences (0 %) but four major complications (18.2 %) and one minor complication (4.5 %) were observed. This concept can be applied in cases of acute abscess formation and in chronic pilonidal sinus disease. The patient's decision with respect to a Limberg plastic surgery procedure for recurrence prophylaxis does not have to be made immediately. In addition, the Limberg plastic surgery procedure is performed in an infection-free stage. The second inpatient stay, second surgical procedure and prolonged time off work are a

    Hidradenitis suppurativa (HS) is a chronic inflammatory disease of apocrine-bearing skin. Treatment is challenging and long-standing. Surgery is one of the treatment options with varying reported success rates. This study provides a comprehensive systematic review of surgical approaches in the management of HS. A systematic literature search and meta-analysis of proportions were performed on the included studies. Of a total of 1147 retrieved articles, 22 were included in the analysis. These were the estimated average recurrences: wide excision, 13.0% (95% confidence interval [CI], 5.0-22.0%); local incision, 22.0% (95% CI, 10.0-37.0%); and deroofing, 27.0% (95% CI, 23.0-31.0%). In the wide excision group, recurrence rates were as follows: 15% (95% CI, 0-72%) for primary closure, 8% (95% CI, 2.0-16.0%) for using flaps, and 6.0% (95% CI, 0.0-24.0%) for grafting. The secondary intention healing option was most commonly chosen after local excision and deroofing. There was poor quality evidence and potential improper reporting of the results. This systematic review found lower recurrence rates with wide excision, using skin flaps or skin grafts as the closure methods. The heterogeneity of the patient populations was high and statistically significant within and across all types of excisions. Copyright © 2015 American Academy of Dermatology, Inc.

    Conclusions: The recurrence of cysts is rare after complete excision, particularly when rupture is prevented. Methylene blue injection is useful for ensuring complete excision and, therefore, to prevent recurrence. [Hand Microsurg 2016; 5(1.000: 1-6

  7. Unusual case of orbital apex syndrome after chalazion excision. (United States)

    Milia, Maria; Lefatzis, Nikolaos; Papakosta, Veroniki; Theodossiadis, Panagiotis; Papathanassiou, Miltiadis


    Orbital apex syndrome represents a heterogeneous group of disorders. It involves damage to the third, fourth and sixth nerves and the ophthalmic division of the fifth cranial nerve, and results in optic neuropathy. An 80-year-old man presented to our emergency clinic with left acute visual loss and three-day history of ocular pain. His medical and ophthalmic history involved diagnosis of lung cancer and chalazion excision two weeks prior to presentation. There was total left ophthalmoplegia, vision was 'no light perception' and he had a relative afferent pupillary defect. An urgent computed tomography scan of the orbits showed sub-periosteal abscess on the lateral wall of the orbit extending to the optic canal. The muscle cone was unaffected. The diagnosis was orbital apex syndrome. He underwent urgent drainage of the abscess and Staphylococcus aureus was identified with Gram stain. He was systemically administered intravenous antibiotics and steroids. His visual acuity and ophthalmoplegia improved rapidly 12 hours after surgery. Prompt diagnosis and treatment in cases of orbital apex syndrome, especially in immunocompromised patients, is important to prevent visual and life-threatening complications. © 2012 The Authors.

  8. Enhanced excision repair activity in mammalian cells after ionizing radiation

    International Nuclear Information System (INIS)

    Bases, R.; Franklin, W.A.; Moy, T.; Mendez, F.


    Monkey CV-1 cells which had received 5 Gy 12 h before harvesting lysates from their cultures contained approximately three times as much DNA excision repair enzyme activity as unirradiated cells, determined in crude cell lysates by the release of intermediate mobility DNA fragments and fragments with 3'-phosphoryl ends from 5'- 32 P-end labelled irradiated 95 bp αDNA. Different 3'-termini endow fragments with differing mobilities, signifying steps in the processing of radiation damaged DNA. Similar results were obtained when Krebs II mouse tumour cells growing in mice as ascites received 5Gy 12 h before harvest. Enzyme activities from CV-1 cells and from Krebs II cells were partially purified as 60-70 kDa proteins on Superose 12 or Ultrogel AcA-54 columns. Divalent cations were not required for enzyme activity. A 23 nucleotide long defined duplex oligodeoxynucleotide substrate containing a single 8-oxodG residue was also very actively cleaved by partially purified cell enzymes. 8-oxoguanine is a major product of ionizing radiation's action on DNA and recognized by the enzymes described here.

  9. Characterization of the anisotropic mechanical properties of excised human skin. (United States)

    Ní Annaidh, Aisling; Bruyère, Karine; Destrade, Michel; Gilchrist, Michael D; Otténio, Mélanie


    The mechanical properties of skin are important for a number of applications including surgery, dermatology, impact biomechanics and forensic science. In this study, we have investigated the influence of location and orientation on the deformation characteristics of 56 samples of excised human skin. Uniaxial tensile tests were carried out at a strain rate of 0.012 s(-1) on skin from the back. Digital Image Correlation was used for 2D strain measurement and a histological examination of the dermis was also performed. The mean ultimate tensile strength (UTS) was 21.6±8.4 MPa, the mean failure strain 54%±17%, the mean initial slope 1.18±0.88 MPa, the mean elastic modulus 83.3±34.9 MPa and the mean strain energy was 3.6±1.6 MJ/m(3). A multivariate analysis of variance has shown that these mechanical properties of skin are dependent upon the orientation of the Langer lines (Pskin using a structural constitutive model.

  10. Implication of Posttranslational Histone Modifications in Nucleotide Excision Repair

    Directory of Open Access Journals (Sweden)

    Shisheng Li


    Full Text Available Histones are highly alkaline proteins that package and order the DNA into chromatin in eukaryotic cells. Nucleotide excision repair (NER is a conserved multistep reaction that removes a wide range of generally bulky and/or helix-distorting DNA lesions. Although the core biochemical mechanism of NER is relatively well known, how cells detect and repair lesions in diverse chromatin environments is still under intensive research. As with all DNA-related processes, the NER machinery must deal with the presence of organized chromatin and the physical obstacles it presents. A huge catalogue of posttranslational histone modifications has been documented. Although a comprehensive understanding of most of these modifications is still lacking, they are believed to be important regulatory elements for many biological processes, including DNA replication and repair, transcription and cell cycle control. Some of these modifications, including acetylation, methylation, phosphorylation and ubiquitination on the four core histones (H2A, H2B, H3 and H4 or the histone H2A variant H2AX, have been found to be implicated in different stages of the NER process. This review will summarize our recent understanding in this area.

  11. Germline excision of transgenes in Aedes aegypti by homing endonucleases. (United States)

    Aryan, Azadeh; Anderson, Michelle A E; Myles, Kevin M; Adelman, Zach N


    Aedes (Ae.) aegypti is the primary vector for dengue viruses (serotypes1-4) and chikungunya virus. Homing endonucleases (HEs) are ancient selfish elements that catalyze double-stranded DNA breaks (DSB) in a highly specific manner. In this report, we show that the HEs Y2-I-AniI, I-CreI and I-SceI are all capable of catalyzing the excision of genomic segments from the Ae. aegypti genome in a heritable manner. Y2-I-AniI demonstrated the highest efficiency at two independent genomic targets, with 20-40% of Y2-I-AniI-treated individuals producing offspring that had lost the target transgene. HE-induced DSBs were found to be repaired via the single-strand annealing (SSA) and non-homologous end-joining (NHEJ) pathways in a manner dependent on the availability of direct repeat sequences in the transgene. These results support the development of HE-based gene editing and gene drive strategies in Ae. aegypti, and confirm the utility of HEs in the manipulation and modification of transgenes in this important vector.

    To quantify iodine uptake in articular cartilage as a marker of glycosaminoglycan (GAG) content using multi-energy spectral CT. We incubated a 25-mm strip of excised osteoarthritic human tibial plateau in 50 % ionic iodine contrast and imaged it using a small-animal spectral scanner with a cadmium telluride photon-processing detector to quantify the iodine through the thickness of the articular cartilage. We imaged both spectroscopic phantoms and osteoarthritic tibial plateau samples. The iodine distribution as an inverse marker of GAG content was presented in the form of 2D and 3D images after applying a basis material decomposition technique to separate iodine in cartilage from bone. We compared this result with a histological section stained for GAG. The iodine in cartilage could be distinguished from subchondral bone and quantified using multi-energy CT. The articular cartilage showed variation in iodine concentration throughout its thickness which appeared to be inversely related to GAG distribution observed in histological sections. Multi-energy CT can quantify ionic iodine contrast (as a marker of GAG content) within articular cartilage and distinguish it from bone by exploiting the energy-specific attenuation profiles of the associated materials.

  13. Retropharyngeal Schwannoma Excised Through a Transoral Approach: A Case Report

    Directory of Open Access Journals (Sweden)

    Chia-Ying Hsieh


    Full Text Available The contents of the retropharyngeal space are limited to fat and retropharyngeal nodes. Primary tumors originating from the retropharyngeal space are rare. More than 25% of schwannomas are found in the head and neck region, and they are rarely found in the retropharyngeal space. Here, we report the case of a 44-year-old woman with a schwannoma confined to the left retropharyngeal space, who presented with snoring and a mild lump in the throat sensation. Physical examination revealed anterior bulging of the left oropharyngeal wall, with intact mucosa. Magnetic resonance imaging showed a well-defined, encapsulated tumor in the left retropharyngeal space with bright signal intensity on T2-weighted images and low signal intensity on T1-weighted images, which was strongly enhanced after gadolinium administration. The tumor was removed through a transoral approach, resulting in a short postoperative recovery time without complications. The pathologic diagnosis was schwannoma. The patient has been well and free of tumor recurrence for 2 years. From anatomic and physiologic viewpoints, excision through a transoral approach is a good choice for a confined retropharyngeal schwannoma.

    Full Text Available ABSTRACT Objective To assess how raising cigarette excise taxes in Peru might impact cigarette consumption, and to determine if higher taxes would be regressive. Methods Total demand price elasticity was estimated by income groups using two datasets: quarterly time-series data from 1993 – 2012 and data from a cross-sectional survey of income and expenses conducted in 2008 – 2009 . A functional form of the cigarette demand in Peru was specified using the quarterly data set, and the demand price elasticity was estimated for the short and long run. Using the second data set and Deaton methodology, the implementation of elasticity estimation and by groups’ elasticity was done in a two-step procedure. Results Demand price elasticity was −0.7, implying that a 10% price increase via a new tax would reduce consumption by 7%. Demand price elasticity estimations by income group suggested that poorer families are not more price sensitive than richer ones, which implies that increasing cigarette taxes could be regressive. Conclusions Increasing cigarette taxes is the most efficient policy for inducing a reduction in smoking. However, in the case of Peru, an increase in cigarette taxes could be regressive.

  16. Total Humeral Endoprosthetic Replacement following Excision of Malignant Bone Tumors

    Directory of Open Access Journals (Sweden)

    Suhel Kotwal


    Full Text Available Humerus is a common site for malignant tumors. Advances in adjuvant therapies and reconstructive methods provide salvage of the upper limb with improved outcomes. Reports of limb salvage with total humeral replacement in extensive humeral tumors are sparse. We undertook a retrospective study of 20 patients who underwent total humeral endoprosthetic replacement as limb salvage following excision of extensile malignant tumor from 1990 to 2011. With an average followup of 42.9, functional and oncological outcomes were analyzed. Ten patients were still alive at the time of review. Mean estimated blood loss was 1131 mL and duration of surgery was 314 minutes. Deep infection was encountered in one patient requiring debridement while mechanical loosening of ulnar component was identified in one patient. Subluxation of prosthetic humeral head was noted in 3 patients. Mean active shoulder abduction was 12.5° and active flexion was 15°. Incompetence of abduction mechanism was the major determinant of poor active functional outcome. Mean elbow flexion was 103.5° with 30.5° flexion contracture in 10 patients with good and useful hand function. Average MSTS score was 71.5%. Total humeral replacement is a reliable treatment option in restoring mechanical stability and reasonable functional results without compromising patient survival, with low complication rate.

  17. Extralevator Abdominal Perineal Excision Versus Standard Abdominal Perineal Excision: Impact on Quality of the Resected Specimen and Postoperative Morbidity. (United States)

    Habr-Gama, Angelita; São Julião, Guilherme P; Mattacheo, Adrian; de Campos-Lobato, Luiz Felipe; Aleman, Edgar; Vailati, Bruna B; Gama-Rodrigues, Joaquim; Perez, Rodrigo Oliva


    Abdominal perineal excision (APE) has been associated with a high risk of positive circumferential resection margin (CRM+) and local recurrence rates in the treatment of rectal cancer. An alternative extralevator approach (ELAPE) has been suggested to improve the quality of resection by avoiding coning of the specimen decreasing the risk of tumor perforation and CRM+. The aim of this study is to compare the quality of the resected specimen and postoperative complication rates between ELAPE and "standard" APE. All patients between 1998 and 2014 undergoing abdominal perineal excision for primary or recurrent rectal cancer at a single Institution were reviewed. Between 1998 and 2008, all patients underwent standard APE. In 2009 ELAPE was introduced at our Institution and all patients requiring APE underwent this alternative procedure (ELAPE). The groups were compared according to pathological characteristics, specimen quality (CRM status, perforation and failure to provide the rectum and anus in a single specimen-fragmentation) and postoperative morbidity. Fifty patients underwent standard APEs, while 22 underwent ELAPE. There were no differences in CRM+ (10.6 vs. 13.6%; p = 0.70) or tumor perforation rates (8 vs. 0%; p = 0.30) between APE and ELAPE. However, ELAPE were less likely to result in a fragmented specimen (42 vs. 4%; p = 0.002). Advanced pT-stage was also a risk factor for specimen fragmentation (p = 0.03). There were no differences in severe (Grade 3/4) postoperative morbidity (13 vs. 10%; p = 0.5). Perineal wound dehiscences were less frequent among ELAPE (52 vs 13%; p < 0.01). Despite short follow-up (median 21 mo.), 2-year local recurrence-free survival was better for patients undergoing ELAPE when compared to APE (87 vs. 49%; p = 0.04). ELAPE may be safely implemented into routine clinical practice with no increase in postoperative morbidity and considerable improvements in the quality of the resected specimen of patients with low rectal

  18. Cigarette price minimization strategies in the United States: price reductions and responsiveness to excise taxes. (United States)

    Pesko, Michael F; Licht, Andrea S; Kruger, Judy M


    Because cigarette price minimization strategies can provide substantial price reductions for individuals continuing their usual smoking behaviors following federal and state cigarette excise tax increases, we examined independent price reductions compensating for overlapping strategies. The possible availability of larger independent price reduction opportunities in states with higher cigarette excise taxes is explored. Regression analysis used the 2006-2007 Tobacco Use Supplement of the Current Population Survey (N = 26,826) to explore national and state-level independent price reductions that smokers obtained from purchasing cigarettes (a) by the carton, (b) in a state with a lower average after-tax cigarette price than in the state of residence, and (c) in "some other way," including online or in another country. Price reductions from these strategies are estimated jointly to compensate for known overlapping strategies. Each strategy reduced the price of cigarettes by 64-94 cents per pack. These price reductions are 9%-22% lower than conventionally estimated results not compensating for overlapping strategies. Price reductions vary substantially by state. Following cigarette excise tax increases, the price reduction available from purchasing cigarettes by cartons increased. Additionally, the price reduction from purchasing cigarettes in a state with a lower average after-tax cigarette price is positively associated with state cigarette excise tax rates and border state cigarette excise tax rate differentials. Findings from this large, nationally representative study of cigarette smokers suggest that price reductions are larger in states with higher cigarette excise taxes, and increase as cigarette excise taxes rise.

    Meimarakis G


    Full Text Available Abstract Background Infection of the spleen with echinococcus is a rare clinical entity. Because the diagnosis of a splenic infestation with echinococcus is sometimes delayed, large hydatid cysts or pseudotumors may develop, demanding a differential surgical approach to cure the disease. Methods In a retrospective study 10 patients out of 250 with abdominal echinococcosis (4% were identified to have splenic infestation, either limited to the spleen (n = 4 or with synchronous involvement of the liver (n = 4, major omentum (n = 1, or the liver and lung (n = 1. Only one patient had alveolar echinococcosis whereas the others showed hydatid cysts of the spleen. Surgical therapy included splenectomy in 7 patients or partial cyst excision combined with omentoplasty in 3 patients. In case of liver involvement, pericystectomy was carried out simultaneously. Results There was no mortality. Postoperative complications were observed in 4 patients. Hospital stay and morbidity were not influenced when splenic procedures were combined with pericystectomies of the liver. Mean follow- up was 8.8 years and all of the patients are free of recurrence at this time. Conclusions Splenectomy should be the preferred treatment of hydatid cysts but partial cystectomy is suitable when the cysts are located at the margins of the spleen. Due to low morbidity rates, simultaneous treatment of splenic and liver hydatid cysts is recom mended.

    Full Text Available Objective: Freiberg disesase is an avascular necrosis of the 2nd and 3rd metatarsal head and which kind of surgical option to be used is controversial in symptomatic patients. In this study the results of the advanced stage Freiberg’s disease patients, who were treated with surgery were evaluated. Methods: 12 patients (8 female, 4 male whose pain could not be solved with conservative method and underwent surgery (6 debridement, 3 osteotomy, 3 excision of the metatarsal head were included in this study. Themean age of the patients 19.1 (range 13- 31 and the mean follow-up 30.8(range 25-94 months. According to the Smillie classification 3 patients had type 5, 8 patients had type 4 and 1 patient had type 3 osteonecrosis. The results of the patients were evaluated according to Lesser Metatarsophalangeal-Interphalangeal Scale. Results: According to Lesser MetatarsophalangealInterphalangeal Scale 3 patients (%25 had excellent, 6 patients (%50 had good and 3 patients had poor results were obtained. 2 of 3 patients with poor results were type 5, and 1 patient was type 4 and all three patients underwent joint debridement. Conclusion:The method of surgical treatment of Freiberg disease determined according to the stage of the disease. Debridement alone in the treatment of patients with late stage is not enough, it should be combined with other methods.

  3. Substrate overlap and functional competition between human nucleotide excision repair and Escherichia coli photolyase and (A)BC excision nuclease

    International Nuclear Information System (INIS)

    Sibghat-Ullah; Sancar, Z.


    Human cell free extract prepared by the method of Manley et al. carries out repair synthesis on UV-irradiated DNA. Removal of pyrimidine dimers by photoreactivation with DNA photolyase reduces repair synthesis by about 50%. With excess enzyme in the reaction mixture photolyase reduced the repair signal by the same amount even in the absence of photoreactivating light, presumably by binding to pyrimidine dimers and interfering with the binding of human damage recognition protein. Similarly, the UvrB subunit of Escherichia coli (A)BC excinuclease when loaded onto UV-irradiated or psoralen-adducted DNA inhibited repair synthesis by cell-free extract by 75-80%. The opposite was true also as HeLa cell free extract specifically inhibited the photorepair of a thymine dimer by DNA photolyase and its removal by (A)BC excinuclease. Cell-free extracts from xeroderma pigmentosum (XP) complementation groups A and C were equally effective in blocking the E. coli repair proteins, while extracts from complementation groups D and E were ineffective in blocking the E. coli enzyme. These results suggest that XP-D and XP-E cells are defective in the damage recognition subunits(s) of human excision nuclease

    Hammond, G.W.; Tehranzadeh, J.; Hoang, B.H. [University of California, Irvine, Department of Orthopaedic Surgery, Orange (United States); Gu, M. [University of California, Irvine, Department of Pathology, Orange (United States)


    A case of soft tissue recurrence of chondroblastoma after attempted en bloc excision and endoprosthetic replacement is described. This tumor in the proximal humerus recurred after initial curettage and was subsequently treated by attempted en bloc excision with positive microscopic margins. The patient then presented with a large soft tissue recurrence surrounding the endoprosthesis. This periprosthetic recurrence necessitated re-excision and revision of the endoprosthesis. Recurrence is not uncommon following curettage of chondroblastoma. However, less is known about soft tissue recurrence after en bloc resection of this tumor with positive margins. A subset of chondroblastoma may exist with more locally aggressive behavior. (orig.)

  5. DNA excision repair as a component of adaptation to low doses of ionizing radiation Escherichia coli

    International Nuclear Information System (INIS)

    Huang, H.; Claycamp, H.G.


    In this study the authors examined whether or not DNA excision repair is a component of adaptation induced by very low-dose ionizing radiation in Escherichia coli, a well-characterized prokaryote, and investigated the relationship between enhanced excision repair and the SOS response. Their data suggest that there seems to be narrow 'windows' of dose-effect for the induction of SOS-independent DNA excision repair. Being similar to mammalian cell studies, the dose range for this effect was about 200-fold less than D 37 for radiation survival. (author)

    CERN Document Server

    Zhuravel, D V


    The influence of the irradiation of different kinds on the indication of the structural mutations in the bacteria Escherichia coli is considered. The regularities of the Tn10 precise excision after accelerated ^{4}He and ^{12}C ions irradiations with different linear energy transfer (LET) were investigated. Dose dependences of the survival and relative frequency of the Tn10 precise excision were obtained. It was shown, that the relative frequency of the Tn10 precise excision is the exponential function from the irradiation dose. Relative biological efficiency (RBE), and relative genetic efficiency (RGE) were calculated, and were treated as the function of the LET.

    Mortelmans, K.; Friedberg, E.C.; Slor, H.; Thomas, G.; Cleaver, J.E.


    Crude extracts of normal human diploid fibroblasts and of human peripheral blood lymphocytes excise thymine dimers from purified ultraviolet-irradiated DNA, or from the DNA presumably present as chromatin in unfractionated cell-free preparations of cells that had been labeled with [ 3 H]thymidine. Extracts of xeroderma pigmentosum cells from complementation groups A, C, and D also excise thymine dimers from purified DNA, but extracts of group A cells do not excise dimers from the DNA of radioactively labeled unfractionated cell-free preparations

  8. A pilot randomized study comparing extralevator with conventional abdominoperineal excision for low rectal cancer after neoadjuvant chemoradiation. (United States)

    Seshadri, R A; West, N P; Sundersingh, S


    The aims of this study were to assess the feasibility of performing an extralevator abdominoperineal excision (ELAPE) after neoadjuvant chemoradiation (NCRT), to compare the rates of circumferential resection margin (CRM) involvement and intra-operative perforation (IOP) of the specimen, and to assess the amount of tissue removed around the muscularis propria (MP)/internal sphincter (IS) of the lower rectum in patients with low rectal cancer undergoing ELAPE compared with conventional abdominoperineal excision (CAPE) after NCRT. This was an open-label, parallel-arm pilot randomized trial conducted in India. Twenty patients were randomized to one of the study arms. The surgical specimens were fixed, serially cross-sectioned and photographed. Using specialized morphometry software, the amount of tissue resected with each operation was measured. There was a nonsignificant trend towards more IOPs (30% vs 0%, P = 0.06) and a higher CRM involvement rate (40% vs 20%, P = 0.32) in the CAPE arm. ELAPE removed a significantly greater amount of tissue around the IS/MP when compared with CAPE (mean ± SD: 1911.39 ± 382 mm 2 vs 1132.03 ± 371 mm 2 , P CRM was significantly greater in the ELAPE arm both in the posterior (mean ± SD: 28.28 ± 3 mm vs 9.63 ± 3 mm, P CRM involvement when compared with CAPE, even after NCRT.

  9. Standard versus extralevator abdominoperineal excision and oncologic outcomes for patients with distal rectal cancer: A meta-analysis. (United States)

    Zhang, Yunfeng; Wang, Duo; Zhu, Lizhe; Wang, Bin; Ma, Xiaoxia; Shi, Bohui; Yan, Yu; Zhou, Can


    The role of extralevator abdominoperineal excision (ELAPE) for distal rectal cancer remains controversial, and the procedure is not widely accepted or practiced. An electronic search of Medline, EMBASE, Web of Science, and similar databases for articles in English was performed from the inception of the study until October 31, 2017. Two reviewers extracted information and independently assessed the quality of included studies by the methodological index for nonrandomized studies, then data were analyzed with Review Manager 5.3 software and Stata version 12.0 software. Our meta-analysis included 17 studies with 3479 patients, of whom 1915 (55.0%) underwent ELAPE and 1564 (44.0%) underwent abdominoperineal excision (APE). Compared with patients undergoing APE, patients undergoing ELAPE had a significant reduced risk of no more than 3 years local recurrence (LR) (risk ratio [RR] = 0.27, 95% confidence interval [CI] = 0.08-0.94), 3-year mortality (odds ratio [OR] = 0.45, 95% CI = 0.20-0.97), intraoperative bowel perforation (IBP) involvement (RR = 0.48, 95% CI = 0.31-0.74), and circumferential resection margin (CRM) positivity (RR = 0.66, 95% CI = 0.43-1.00) at the threshold level. The application of ELAPE is more effective in reducing the chance of 3 years LR, mortality, IBP involvement and CRM positivity than conventional APE, and worthy of being widely applied in surgical treatment of the distal rectal cancer.

  10. Endoscopic Versus Open Excision of Os Trigonum for the Treatment of Posterior Ankle Impingement Syndrome in an Athletic Population: A Randomized Controlled Study With 5-Year Follow-up. (United States)

    Georgiannos, Dimitrios; Bisbinas, Ilias


    Open surgical excision of the os trigonum has been the traditional treatment for posterior ankle impingement syndrome (PAIS). However, the endoscopic excision has recently become quite popular. Purpose/Hypothesis: The purpose of our study was to compare the results of endoscopic versus open excision of a symptomatic os trigonum for the treatment of PAIS in an athletic population. It was hypothesized that the endoscopic technique would be superior to the open technique regarding functional outcomes, pain, and time to return to training and the previous sports level. Randomized controlled trial; Level of evidence, 2. From 2008 to 2011, 52 athletes underwent a symptomatic os trigonum excision; 26 athletes had an open procedure (group A) and 26 had an endoscopic procedure (group B). The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score and the Visual Analog Score-Foot and Ankle (VAS-FA) were obtained, and the time to return to training and to previous sports level was recorded. Patients in group B appeared to have significant improvement of AOFAS hindfoot score compared with those in group A ( P os trigonum is a safe and effective treatment option for athletes who require early return to their previous sports level.

  11. Deriving DICOM surgical extensions from surgical workflows (United States)

    Burgert, O.; Neumuth, T.; Gessat, M.; Jacobs, S.; Lemke, H. U.


    The generation, storage, transfer, and representation of image data in radiology are standardized by DICOM. To cover the needs of image guided surgery or computer assisted surgery in general one needs to handle patient information besides image data. A large number of objects must be defined in DICOM to address the needs of surgery. We propose an analysis process based on Surgical Workflows that helps to identify these objects together with use cases and requirements motivating for their specification. As the first result we confirmed the need for the specification of representation and transfer of geometric models. The analysis of Surgical Workflows has shown that geometric models are widely used to represent planned procedure steps, surgical tools, anatomical structures, or prosthesis in the context of surgical planning, image guided surgery, augmented reality, and simulation. By now, the models are stored and transferred in several file formats bare of contextual information. The standardization of data types including contextual information and specifications for handling of geometric models allows a broader usage of such models. This paper explains the specification process leading to Geometry Mesh Service Object Pair classes. This process can be a template for the definition of further DICOM classes.

  12. Two-stage surgical removal of large complex odontoma. (United States)

    Chrcanovic, Bruno Ramos; Jaeger, Filipe; Freire-Maia, Belini


    The surgical treatment of a large complex odontoma in the mandibular angle is reported. Four possible surgical approaches to remove a benign tumor in the mandibular angle are discussed. A two-stage surgical treatment was chosen; first, removing most part of the lesion and preserving the second molar, decreasing the risk of a pathological mandibular fracture. A maxillo-mandibular fixation for a period of 4 weeks was used. The patient was oriented to maintain a soft diet. The second surgical stage occurred 3 months after the first one due to the significant bone consolidation observed, reducing the possibility of a mandibular fracture. The remaining lesion and the second molar were then completely removed. This case demonstrates the value of the tridimensional computed tomography in treatment planning prior to any definitive surgery. A computed tomography should be made in every case of intraosseous lesion in order to establish the intraosseous extent of the tumor, cortical perforation, and soft tissue involvement for precise guidance for the surgical planning. It is recommended that the surgeon considers excision by an intraoral, lingual approach when indicated, and in two stages, when an extremely thin mandibular base is present.

  13. Oncological outcome after laparoscopic abdominoperineal excision of the rectum. (United States)

    Jefferies, M T; Evans, M D; Hilton, J; Chandrasekaran, T V; Beynon, J; Khot, U


    Abdominoperineal excision of the rectum (APER) for cancer has been associated with higher circumferential resection margin (CRM) involvement and failure of local disease control. The aim of this study was to investigate whether the introduction of laparoscopic APER altered the incidence of CRM involvement. Consecutive patients undergoing open or laparoscopic APER for adenocarcinomas of the rectum were studied. Patient demographics, preoperative staging, neoadjuvant treatment, operative findings, length of stay and pathological details were collected from operative and radiology databases and compared. There were 16 laparoscopic and 25 open APER performed over a 3-year period. Neoadjuvant therapy was given to 43.8% (7/16) of the laparoscopic group and 56.0% (14/25) of the open group. Complete laparoscopic resection was possible in 14 (87.5%) of 16 patients. The median harvested number of nodes was 14 (4-33) in both groups. The median length of stay was 7 (3-13) and 15 (9-40) days in the laparoscopic and open groups (P CRM was clear in all cases. There was no local recurrence in either group at a median follow-up of 23 months. There were no in-hospital deaths and no significant differences in overall survival. There were no significant differences in preoperative or postoperative histopathological T stage between the two groups (P = 0.057 and P = 0.121). Laparoscopic APER for selected rectal cancers can achieve comparable oncological outcome to open surgery but is associated with a much shorter length of stay. Patient and tumour characteristics must be taken into consideration when deciding on a laparoscopic approach for low rectal cancer. © 2011 The Authors.

  14. Radiation induced base excision repair (BER): a mechanistic mathematical approach. (United States)

    Rahmanian, Shirin; Taleei, Reza; Nikjoo, Hooshang


    This paper presents a mechanistic model of base excision repair (BER) pathway for the repair of single-stand breaks (SSBs) and oxidized base lesions produced by ionizing radiation (IR). The model is based on law of mass action kinetics to translate the biochemical processes involved, step-by-step, in the BER pathway to translate into mathematical equations. The BER is divided into two subpathways, short-patch repair (SPR) and long-patch repair (LPR). SPR involves in replacement of single nucleotide via Pol β and ligation of the ends via XRCC1 and Ligase III, while LPR involves in replacement of multiple nucleotides via PCNA, Pol δ/ɛ and FEN 1, and ligation via Ligase I. A hallmark of IR is the production of closely spaced lesions within a turn of DNA helix (named complex lesions), which have been attributed to a slower repair process. The model presented considers fast and slow component of BER kinetics by assigning SPR for simple lesions and LPR for complex lesions. In the absence of in vivo reaction rate constants for the BER proteins, we have deduced a set of rate constants based on different published experimental measurements including accumulation kinetics obtained from UVA irradiation, overall SSB repair kinetic experiments, and overall BER kinetics from live-cell imaging experiments. The model was further used to calculate the repair kinetics of complex base lesions via the LPR subpathway and compared to foci kinetic experiments for cells irradiated with γ rays, Si, and Fe ions. The model calculation show good agreement with experimental measurements for both overall repair and repair of complex lesions. Furthermore, using the model we explored different mechanisms responsible for inhibition of repair when higher LET and HZE particles are used and concluded that increasing the damage complexity can inhibit initiation of LPR after the AP site removal step in BER.

  15. Base excision repair deficiency in acute myeloid leukemia

    International Nuclear Information System (INIS)

    Scheer, N.M.


    Acute myeloid leukemia (AML) is an aggressive malignancy of the hematopoietic system arising from a transformed myeloid progenitor cell. Genomic instability is the hallmark of AML and characterized by a variety of cytogenetic and molecular abnormalities. Whereas 10% to 20% of AML cases reflect long-term sequelae of cytotoxic therapies for a primary disorder, the etiology for the majority of AMLs remains unknown. The integrity of DNA is under continuous attack from a variety of exogenous and endogenous DNA damaging agents. The majority of DNA damage is caused by constantly generated reactive oxygen species (ROS) resulting from metabolic by-products. Base excision repair (BER) is the major DNA repair mechanism dealing with DNA base lesions that are induced by oxidative stress or alkylation. In this study we investigated the BER in AML. Primary AML patients samples as well as AML cell lines were treated with hydrogen peroxide (H 2 O 2 ). DNA damage induction and repair was monitored by the alkaline comet assay. In 15/30 leukemic samples from patients with therapy-related AML, in 13/35 with de novo AML and 14/26 with AML following a myelodysplastic syndrome, significantly reduced single strand breaks (SSBs) representing BER intermediates were found. In contrast, normal SSB formation was seen in mononuclear cells of 30 healthy individuals and 30/31 purified hematopoietic stem- and progenitor cell preparations obtained from umbilical cord blood. Additionally, in 5/10 analyzed AML cell lines, no SSBs were formed upon H 2 O 2 treatment, either. Differences in intracellular ROS concentrations or apoptosis could be excluded as reason for this phenomenon. A significantly diminished cleavage capacity for 7,8-dihydro-8-oxoguanine as well as for Furan was observed in cell lines that exhibited no SSB formation. These data demonstrate for the first time that initial steps of BER are impaired in a proportion of AML cell lines and leukemic cells from patients with different forms of

  16. Ku80-deleted cells are defective at base excision repair

    Li, Han; Marple, Teresa; Hasty, Paul


    Graphical abstract: - Highlights: • Ku80-deleted cells are hypersensitive to ROS and alkylating agents. • Cells deleted for Ku80, but not Ku70 or Lig4, have reduced BER capacity. • OGG1 rescues hypersensitivity to H 2 O 2 and paraquat in Ku80-mutant cells. • Cells deleted for Ku80, but not Lig4, are defective at repairing AP sites. • Cells deleted for Ku80, but not Lig4 or Brca2 exon 27, exhibit increased PAR. - Abstract: Ku80 forms a heterodimer with Ku70, called Ku, that repairs DNA double-strand breaks (DSBs) via the nonhomologous end joining (NHEJ) pathway. As a consequence of deleting NHEJ, Ku80-mutant cells are hypersensitive to agents that cause DNA DSBs like ionizing radiation. Here we show that Ku80 deletion also decreased resistance to ROS and alkylating agents that typically cause base lesions and single-strand breaks (SSBs). This is unusual since base excision repair (BER), not NHEJ, typically repairs these types of lesions. However, we show that deletion of another NHEJ protein, DNA ligase IV (Lig4), did not cause hypersensitivity to these agents. In addition, the ROS and alkylating agents did not induce γ-H2AX foci that are diagnostic of DSBs. Furthermore, deletion of Ku80, but not Lig4 or Ku70, reduced BER capacity. Ku80 deletion also impaired BER at the initial lesion recognition/strand scission step; thus, involvement of a DSB is unlikely. Therefore, our data suggests that Ku80 deletion impairs BER via a mechanism that does not repair DSBs

    Keratoconus (KC) is a degenerative corneal disorder for which the exact pathogenesis is not yet known. Oxidative stress is reported to be associated with this disease. The stress may damage corneal biomolecules, including DNA, and such damage is primarily removed by base excision repair (BER). Variation in genes encoding BER components may influence the effectiveness of corneal cells to cope with oxidative stress. In the present work we genotyped 5 polymorphisms of 4 BER genes in 284 patients and 353 controls. The A/A genotype of the c.–1370T>A polymorphism of the DNA polymerase γ (POLG) gene was associated with increased occurrence of KC, while the A/T genotype was associated with decreased occurrence of KC. The A/G genotype and the A allele of the c.1196A>G polymorphism of the X-ray repair cross-complementing group 1 (XRCC1) were associated with increased, and the G/G genotype and the G allele, with decreased KC occurrence. Also, the C/T and T as well as C/C genotypes and alleles of the c.580C>T polymorphism of the same gene displayed relationship with KC occurrence. Neither the g.46438521G>C polymorphism of the Nei endonuclease VIII-like 1 (NEIL1) nor the c.2285T>C polymorphism of the poly(ADP-ribose) polymerase-1 (PARP-1) was associated with KC. In conclusion, the variability of the XRCC1 and POLG genes may play a role in KC pathogenesis and determine the risk of this disease. PMID:25356504

  19. Induced macrophage activation in live excised atherosclerotic plaque. (United States)

    Prebble, Hannah; Cross, Sean; Marks, Edward; Healy, Joe; Searle, Emily; Aamir, Raja; Butler, Anthony; Roake, Justin; Hock, Barry; Anderson, Nigel; Gieseg, Steven P


    Atherosclerotic plaques are complex tissues containing many different cell types. Macrophages contribute to inflammation, formation of the necrotic core, and plaque rupture. We examined whether macrophages in plaque can be activated and compared this to monolayer cells. The volume of calcium in the plaque was compared to the level of macrophage activation measured by total neopterin output. Carotid plaque samples were cut into 3 mm sections and cultured for up to 96 h. Live sections were stimulated with interferon-γ, phytohaemagglutinin or phorbol 12-myristate 13-acetate. Macrophage activation and oxidative stress were monitored by total neopterin (oxidized and non-oxidized 7,8-dihydroneopterin) and neopterin levels every 24 h for up to 4 d. The calcium content of two plaques was investigated by spectral imaging. Direct stimulation of macrophages in plaque sections with interferon-γ caused a sustained increase in neopterin (p = .037) and total neopterin (p = .003). The addition of phorbol 12-myristate 13-acetate to plaque had no significant effect on total neopterin production (p = .073) but increased neopterin (p = .037) whereas phytohaemagglutinin caused a significant increase in both neopterin and total neopterin (p = .0279 and .0168). There was an inverse association (R 2  = 0.91) between the volume of calcium and macrophage activation as measured by total neopterin production in stimulated plaque tissue. Resident macrophages within excised carotid plaque activated either directly or indirectly generate the biomarkers 7,8-dihydroneopterin and neopterin. Macrophage activation rather than the oxidative environment is associated with plaque calcification. Copyright © 2018 Elsevier GmbH. All rights reserved.

  20. Loop electrosurgical excision procedure with an intrauterine device in place. (United States)

    Bailey, Amelia P; Darracott, Mixon M


    Patients using an intrauterine device (IUD) who require a loop electrosurgical excision procedure (LEEP) for cervical dysplasia have traditionally had the IUD removed prior to the procedure. The only other options have been methods that lead to suboptimal sampling or risk cutting the strings. Our study suggests a procedure for performing the LEEP without removing the IUD, and review of the literature suggests that this method has not been reported before. The LEEP is performed using a conization electrode or a cone biopsy excisor. After noting that the IUD strings are of adequate length, a 0-polyglactin free tie is secured around the visible portion of the IUD strings without applying tension on the strings. A large, sterile absorbent-tipped applicator with a hollow handle becomes an 8 cm hollow plastic tube by removing the cotton tip with sterile scissors. The long end of the suture is threaded through the sterile tube. Without pulling on the IUD, the tube is then passed over the strings into the cervical canal approximately 2.5 cm to protect the strings from the excisor well into the cervical canal. Then, the LEEP is performed. After the specimen is removed, hemostasis can be obtained using a ball cautery electrode, keeping the protecting tube with the enclosed IUD strings out of the way. The tube is then carefully removed. The suture is now cut close to the polyglactin knot around the IUD strings, making certain not to shorten the IUD strings and making certain the visible length of the strings is the same as before the procedure. Ferric subsulfate is applied to the operative area to provide continued hemostasis. Follow-up for the LEEP is unchanged. This procedure may be performed on either levonorgestrel-releasing or copper IUDs. Copyright 2010 Mosby, Inc. All rights reserved.

    Graphical abstract: - Highlights: • Ku80-deleted cells are hypersensitive to ROS and alkylating agents. • Cells deleted for Ku80, but not Ku70 or Lig4, have reduced BER capacity. • OGG1 rescues hypersensitivity to H{sub 2}O{sub 2} and paraquat in Ku80-mutant cells. • Cells deleted for Ku80, but not Lig4, are defective at repairing AP sites. • Cells deleted for Ku80, but not Lig4 or Brca2 exon 27, exhibit increased PAR. - Abstract: Ku80 forms a heterodimer with Ku70, called Ku, that repairs DNA double-strand breaks (DSBs) via the nonhomologous end joining (NHEJ) pathway. As a consequence of deleting NHEJ, Ku80-mutant cells are hypersensitive to agents that cause DNA DSBs like ionizing radiation. Here we show that Ku80 deletion also decreased resistance to ROS and alkylating agents that typically cause base lesions and single-strand breaks (SSBs). This is unusual since base excision repair (BER), not NHEJ, typically repairs these types of lesions. However, we show that deletion of another NHEJ protein, DNA ligase IV (Lig4), did not cause hypersensitivity to these agents. In addition, the ROS and alkylating agents did not induce γ-H2AX foci that are diagnostic of DSBs. Furthermore, deletion of Ku80, but not Lig4 or Ku70, reduced BER capacity. Ku80 deletion also impaired BER at the initial lesion recognition/strand scission step; thus, involvement of a DSB is unlikely. Therefore, our data suggests that Ku80 deletion impairs BER via a mechanism that does not repair DSBs.

  7. Novel surgical approach for axillary hidradenitis suppurativa using a bilayer dermal regeneration template: a retrospective case study. (United States)

    Gonzaga, Teresa A; Endorf, Frederick W; Mohr, William J; Ahrenholz, David H


    Hidradenitis suppurativa (HS) is a chronic debilitating disease of apocrine gland-bearing skin characterized by recurrent abscesses with subsequent rupture, scarring, and draining sinus tracts, most frequently affecting the axillary, inguinal, and anogenital regions. Conservative and temporizing treatment methods have been used to treat mild to moderate disease, but wide local excision of affected tissue is necessary for advanced disease. This creates a large soft tissue defect for which there is no consensus for reconstruction. Recovery is hampered by disease recurrence, tissue necrosis, and reoperation. The authors have described in this case study an alternative surgical approach to treat severe HS. All surgical procedures were performed by dedicated burn surgeons at a regional burn center using a two-stage surgical approach. The first stage is a wide local excision of all affected axillary tissue with immediate placement of a bilayer dermal regeneration template to cover the defect. This is secured with a negative pressure wound therapy dressing. The second stage uses a thin split thickness skin graft to close the wound. Results of four patients are presented. There were no recurrences of HS. Two patients required reoperations to address granulation tissue overgrowth and small areas of autograft loss. One patient experienced skin substitute loss as a result of infection. Inadequate excision of HS is the leading cause of disease recurrence. Using a bilayer dermal regeneration template with subsequent skin graft, surgeons can be aggressive in their excision of HS, achieving satisfactory functional and cosmetic results and minimizing axillary recurrence.

    Biuk, Dubravka; Matić, Suzana; Barać, Josip; Vuković, Marija Jelić; Biuk, Egon; Matić, Mate


    The aim of the study was to compare the length of treatment and efficiency of applied therapy in two groups of patients with chalazion who underwent surgical procedure or got triamcinolone application in chalazion. Our study included 30 patients with chalazions that persisted for about one month. All of them were resistant to applied topical antimicrobial therapy. These patients were devided in two groups. 15 patients underwent surgical procedure that included incision, excochleation and excision of the capsule of chalazion, while other 15 patients underwent triamcinolone aplication directly in chalazion (dosage of 2-4 mg). Patients were followed up a day after therapy, two weeks after therapy and one month after applied therapy. We found that chalazion treatment with triamcinolone application directly in the lesion was to be more comfortable for patients, took less time to treat and needed no additional topical antimicrobial therapy.

  9. Thoracolumbar extradural arachnoid cyst--three surgical case reports. (United States)

    Tomii, Masato; Mizuno, Junichi; Takeda, Masaaki; Matsushima, Tadao; Itoh, Yasunobu; Numazawa, Shinichi; Matsuoka, Hidenori; Watanabe, Kazuo


    Three cases of symptomatic extradural arachnoid cyst were treated by surgery. Total excision of the cyst followed by tight closure of the fistula by suture was achieved in all 3 cases. Surgery improved the neurological deficits but urinary incontinence persisted in all three patients. Obliteration of the fistula is considered to be important at surgery from the etiological perspective of the cyst. There are many surgical options, but surgical removal of the cyst and obliteration of the communication usually leads to prompt improvement in neurological deficits. Instability, malalignment, and worsening scoliosis are well-recognized postoperative complications of excessive laminotomy, but the exposure should be wide enough to cover the cyst completely at the operation. Wide exposure of the entire cyst is preferable to avoid missing the fistula and to identify any adhesions or fistula between the cyst and the dura. Identification of the fistula location based on preoperative imaging studies is also important.

  10. Surgical treatment of an unusual case of pelvic extramedullary hematopoiesis. (United States)

    Khen-Dunlop, Naziha; Girot, Robert; Brunelle, Francis; Révillon, Yann; Nihoul-Fékété, Claire; Sarnacki, Sabine


    Extramedullary hematopoiesis affects about 15% of the patients treated for thalassemia intermedia. Usually seen in adulthood, the most common location is the paraspinal region. Diagnosis and treatment of extramedullary hematopoiesis located in the pelvis of a young 15-year-old girl is discussed. The young age of the patient and the uncommon site of the mass first lead to the diagnosis of an ovarian dermoid cyst. Because of the clinical history and the typical feature on computed tomography scan, extramedullary hematopoiesis was concluded. A specific treatment based on blood transfusion and hydroxyurea was first proposed but remained inefficient. Surgical excision was thus successfully performed. Whereas surgery is limited to spinal cord compression in paraspinal extramedullary hematopoiesis, this observation argues for surgical treatment in symptomatic intraabdominal extramedullary hematopoiesis when medical treatment fails.

  11. Evaluation of adjuvant carboplatin chemotherapy in the management of surgically excised anal sac apocrine gland adenocarcinoma in dogs. (United States)

    Wouda, R M; Borrego, J; Keuler, N S; Stein, T


    There is no widely accepted standard of care for canine anal sac apocrine gland adenocarcinoma (ASAGAC). Surgery alone is inadequate in many cases, but the benefit of adjuvant chemotherapy is not well established. The primary objective of this retrospective study was to evaluate the role of carboplatin chemotherapy in the post-operative management of ASAGAC. Seventy-four dogs with naturally occurring ASAGAC underwent surgery. Forty-four dogs received adjuvant carboplatin and 30 did not. Median overall survival (OS) was 703 days. Median time to progression (TTP) was 384 days. Only primary tumour size and lymph node metastasis at diagnosis significantly impacted the outcome. Differences in OS and TTP, between the dogs that received adjuvant carboplatin and those that did not, failed to reach statistical significance. Treatment of progressive disease, whilst not limited to chemotherapy, significantly prolonged the survival. This study shows that adjuvant carboplatin chemotherapy is well tolerated and may have a role in the management of dogs with ASAGAC. © 2013 John Wiley & Sons Ltd.

  12. Quantitative characterization of pyrimidine dimer excision from UV-irradiated DNA (excision capacity) by cell-free extracts of the yeast Saccharomyces cerevisiae

    International Nuclear Information System (INIS)

    Bekker, M.L.; Kaboev, O.K.; Akhmedov, A.T.; Luchkina, L.A.


    Cell-free extracts from wild-type yeast (RAD + ) and from rad mutants belonging to the RAD3 epistatic group (rad1-1, rad2-1, rad3-1, rad4-1) contain activities catalyzing the excision of pyrimidine dimers (PD) from purified ultraviolet-irradiated DNA which was not pre-treated with exogenous UV-endonuclease. The level of these activities in cell-free extracts from rad mutants did not differ from that in wild-type extract and was close to the in vivo excision capacity of the latter calculated from the LD 37 (about 10 4 PD per haploid genome).

    Angiero, Francesca; Benedicenti, Stefano; Parker, Steven; Signore, Antonio; Sorrenti, Eugenio; Giacometti, Edoardo; Crippa, Rolando


    Odontomas are hamartomatous developmental malformations of the dental tissues. We present a retrospective study of recent clinical experience using erbium-doped yttrium aluminum garnet (Er:YAG) (wavelength 2940 nm) and chromium-doped yttrium scandium gallium garnet lasers (Er,Cr:YSSG) (wavelength 2780 nm) for the surgical treatment of these lesions, and score postsurgical pain. This retrospective study comprised 35 odontomas treated at the Department of Oral Pathology and Laser-Assisted Surgery, San Martino Hospital, University of Genoa, Italy. Of 35 Caucasian patients (23 male, 12 female; ages 8-35; odontomas localized at various oral subsites) those in Group 1 (n=25) had odontomas excised by laser (Er:YAG laser operating at 2940 nm, pulse width 100 msec, curved handpiece, truncated cone HPX tip, 400 μm with energy output 250-400 mJ per pulse, frequency 15 Hz; and Er, Cr: YSGG laser, power 3.5 W, frequency 20 Hz, 55% air/45% water spray, H (hard tissue) mode, pulse width 190-750 μsec variable). In Group 2 (n=10) odontomas were excised by conventional surgery. Pain was assessed using a visual analog scale (VAS). Clinical outcome was determined at 6-12 months. Complete responses were achieved in 100% of the laser-treated odontomas, which compares favorably with reported results of conventional surgery. A statistically significant difference in VAS score was found between patients treated with traditional scalpel surgery (median=4.00) and those who underwent laser surgery (median=3.00). In treating odontomas, a laser surgery protocol effectively minimizes pain, maintains an excellent clinical outcome, and requires minimal additional treatment time compared with conventional surgery.

  14. Etiologic revelation and outcome of the surgical management of idiopathic granulomatous mastitis; An Egyptian centre experience. (United States)

    Elzahaby, Islam A; Khater, Ashraf; Fathi, Adel; Hany, Islam; Abdelkhalek, Mohamed; Gaballah, Khaled; Elalfy, Amr; Hamdy, Omar


    Idiopathic granulomatous mastitis (IGM) is a chronic inflammatory condition that is confused with cancer. It usually affects women in child bearing age. The exact aetiology and pathogenesis are still unknown, and the optimal therapeutic modality has not yet been established. Treatment most frequently includes Antibiotics, corticosteroids and immunosuppressant, surgical excision, and even mastectomy. We studied a thirty cases diagnosed with IGM in our locality to find out the leading risk factors and the outcome of our surgical approach which involves excision of the lesion in continuity with duct system. Patients demographic data, history related to lactation and outcome were recorded. All patients were parous women with history of previous breast feeding for all kids. Twenty-six patients (86.66%) had a history of early incomplete nursing care to the affected breast. After our surgical approach, Twenty eight (93.3%) patients showed fast recovery with no detectable recurrences in the median follow up period (18 months) with acceptable cosmoses. History of breast feeding together with early failure of complete nursing from a single breast is the most important risk factors for development of IGM in young aged women. Surgery plays an important role in treating IGM, however, it should be directed towards excision of the present mass (s) together with the pathological and colonized duct system.

  16. Effects of early excision and aggressive enteral feeding on hypermetabolism, catabolism, and sepsis after severe burn. (United States)

    Hart, David W; Wolf, Steven E; Chinkes, David L; Beauford, Robert B; Mlcak, Ronald P; Heggers, John P; Wolfe, Robert R; Herndon, David N


    Severe burn induces a systemic hypermetabolic response, which includes increased energy expenditure, protein catabolism, and diminished immunity. We hypothesized that early burn excision and aggressive enteral feeding diminish hypermetabolism. Forty-six burned children were enrolled into a cohort analytic study. Cohorts were segregated according to time from burn to transfer to our institution for excision, grafting, and nutritional support. No subject had undergone wound excision or continuous nutritional support before transfer. Resting energy expenditure, skeletal muscle protein kinetics, the degree of bacterial colonization from quantitative cultures, and the incidence of burn sepsis were measured as outcome variables. Early, aggressive treatment did not decrease energy expenditure; however, it did markedly attenuate muscle protein catabolism when compared with delay in aggressive treatment. Wound colonization and sepsis were diminished in the early treatment group as well. Early excision and concurrent aggressive feeding attenuate muscle catabolism and improve infectious outcomes after burn.

  20. Clinical experience of surgically treating giant neurofibromatosis-1. (United States)

    Chen, Baoguo; Xu, Minghuo; Song, Huifeng; Gao, Quanwen


    The surgical treatment for giant neurofibromatosis-1 (NF-1) requires comprehensive measures. Presently, there is no systematic description of surgical treatment. Because of its high level of risk, we want to share our clinical experience. From 2011 to 2014, patients (n = 8, 5 female and 3 male patients, aging from 31 to 45 years-old) were included in the study. The tumours were located on the trunk (n = 5) or face (n = 3). In addition to routine examination, blood storage was also prepared. Preoperative consultation from related departments was critical at first. Related artery embolisation was also carried out. In the operation, we checked thromboelastography, based on which reasonable blood component transfusion was implemented. Autologous blood transfusion was also ready. An instrument of copper needle or ring ligation was used to reduce haemorrhage before the surgery. Protruding or drooping portions of the tumours were excised. A pressurised bandage was applied when the surgery was completed. After the surgery, besides the routine monitoring of vital signs, re-haemorrhage should be detected in time. Then, we should decide whether blood transfusion or surgery was required again. Expanders were implanted in one female patient with facial injuries before removing the tumour. Then, expanded flaps were applied to repair the secondary wound. According to the above clinical route, after an average of 1-year follow-up, no patients died, and other unforeseen events did not occur. Wounds healed well in all patients. The tumor was excised as much as possible. No facial nerve paralysis occurred in the facial sites. Expanded flaps necrosis WAS not encountered. It is essential to design the educational clinical route for treating NF-1 when a giant protruding tumour is advised to be excised, which can minimise the risk of surgery and assure us of the maximum range of resection. © 2016 Inc and John Wiley & Sons Ltd.

  1. Recapping hemilaminoplasty for spinal surgical disorders using ultrasonic bone curette. (United States)

    Matsuoka, Hidenori; Itoh, Yasunobu; Numazawa, Shinichi; Tomii, Masato; Watanabe, Kazuo; Hirano, Yoshitaka; Nakagawa, Hiroshi


    The authors present a novel method of the recapping hemilaminoplasty in a retrospective study of patients with spinal surgical disorders. This report describes the surgical technique and the results of hemilaminoplasty using an ultrasonic bone curette. The aim of this study was to examine the safety and effectiveness of the hemilaminoplasty technique with ultrasonic bone curette. Between April 2003 and July 2011, 33 patients with various spinal diseases (17 spinal tumors, 5 dural arteriovenous fistulas, 3 syringomyelia, 2 sacral perineural cysts, and 2 arachnoid cysts) were treated microsurgically by using an ultrasonic bone curette with scalpel blade and lightweight handpiece. The ultrasonic bone curette was used for division of lamina. After resection of the lesion, the excised lamina was replaced exactly in situ to its original anatomic position with a titanium plate and screw. Additional fusion technique was not required and the device was easy to handle. All patients were observed both neurologically and radiologically by dynamic plain radiographs and computed tomography (CT) scan. The operation was performed successfully and there were no instrument-related complications such as dural laceration, nerve root injury, and vessels injury. The mean number of resected and restored lamina was 1.7. CT confirmed primary bone fusion in all patients by 12 months after surgery. The ultrasonic bone curette is a useful instrument for recapping hemilaminoplasty in various spinal surgeries. This method allows anatomical reconstruction of the excised bone to preserve the posterior surrounding tissues.

  2. Results of surgical treatment of unresolved Osgood-Schlatter lesion. (United States)

    Orava, S; Malinen, L; Karpakka, J; Kvist, M; Leppilahti, J; Rantanen, J; Kujala, U M


    We present our experience with surgical treatment of unresolved, painful, late Osgood-Schlatter disease. In 70 operations performed in 67 patients (in three bilaterally) an ossicle under the distal patellar tendon was removed in 62 cases. In eight cases, excision of the prominent tibial tubercle and/or drilling of the epiphysis was performed. Additional procedures, such as rasping of the uneven anterior tibial surface, excision of inflammed bursa or the devitalized portion of the tendon, were done 21 times. Most patients were athletes or physically active young people. The mean age was 19.6 years. 54 operations were done on males and 16 on females. They had been followed preoperatively for 18 months and after surgery 2.2 years. The final results were excellent or good in 56, moderate in 9, poor in 3 and unknown in 2 cases. Osgood-Schlatter's disease may leave an ossicle under the distal patellar tendon, a prominent tibial tubercle or an uneven surface of anterior superior tibia. These may lead to pain and disability due to recurrent injuries or athletic exercises. Surgical treatment gives good results in chronic unresolved cases.

    We determined the average size of excision repair patches in repair of UV lesions in bacteriophage T4 by measuring the photolysis of bromodeoxyuridine incorporated during repair. The average patch was small, approximately four nucleotides long. In control experiments with the denV1 excision-deficient mutant, we encountered an artifact, a protein(s) which remained bound to phenol-extracted DNA and prevented nicking by the UV-specific endonucleases of Micrococcus luteus and bacteriophage T4

    Yang, Yingchi; Wang, Jin; Jin, Lan; Zhao, Xiaomu; Wu, Guocong; Wang, Kangli; Zhang, Zhongtao


    To verify the clinical safety of complete mesocolic excision (CME) and manufacture pathological large slices. A prospective analysis clinical data of 85 right colon cancer in patients by the same group of surgeons at the Department of General Surgery, Beijing Friendship Hospital, Capital Medical University from January 2012 to December 2013 which were divided into two groups: CME group (n=39) and traditional radical operation group (n=46) by surgical approach. CME group and control group were compared the differences of clinic and pathologic variables, precise tissues morphometry, lymph nodes harvest, mesocolic area and so on. By comparison to operation time, blood loss, postoperative complications, flatus restoring time, drainage removal time and length of stay, the security of CME was analyzed. Statistical methods included independent sample t-test, Wilcoxon rank sum test and χ(2) test. In order to manufacture pathological large slices, the CME operation specimens were fixed. The large slices were stained by routine HE staining to detection of circumferential resection margin. Mean number of total lymph nodes was increased obviously in CME group (26.8±1.9 vs. 23.2±3.4, t=4.261, P=0.000). Mean number of lymph nodes of stage Ⅰ, Ⅱ were different between two groups (25.8±3.6 vs. 18.2±4.5, 26.8±7.7 vs. 24.9±6.2, t=8.776, 2.802, P=0.000). The positive lymph nodes of CME group was higher than control group (4(7) vs. 1.5(2), P=0.032), above all with statistically significant difference. Comparing CME group with the control group, there were the larger area of mesentery ((15 555±1 263) mm(2) vs. (12 493±1 002) mm(2,) t=12.456, P=0.000), the greater distance between the tumor and the high vascular tie ((116±22) mm vs. (82±11) mm, t=9.295, P=0.000), the greater distance between the normal bowel and the high vascular tie ((92±17) mm vs. (74±10) mm, t=8.132, P=0.000) of CME, with statistically significant difference. There were no statistically significant

  7. Timing of Developmentally Programmed Excision and Circularization of Paramecium Internal Eliminated Sequences (United States)

    Bétermier, Mireille; Duharcourt, Sandra; Seitz, Hervé; Meyer, Eric


    Paramecium internal eliminated sequences (IESs) are short AT-rich DNA elements that are precisely eliminated from the germ line genome during development of the somatic macronucleus. They are flanked by one 5′-TA-3′ dinucleotide on each side, a single copy of which remains at the donor site after excision. The timing of their excision was examined in synchronized conjugating cells by quantitative PCR. Significant amplification of the germ line genome was observed prior to IES excision, which starts 12 to 14 h after initiation of conjugation and extends over a 2- to 4-h period. Following excision, two IESs were shown to form extrachromosomal circles that can be readily detected on Southern blots of genomic DNA from cells undergoing macronuclear development. On these circular molecules, covalently joined IES ends are separated by one copy of the flanking 5′-TA-3′ repeat. The similar structures of the junctions formed on the excised and donor molecules point to a central role for this dinucleotide in IES excision. PMID:10669733

  8. Surgical ethics: surgical virtue and more. (United States)

    Vercler, Christian J


    The encounter between a patient and her surgeon is unique for several reasons. The surgeon inflicts pain upon a patient for the patient's own good. An operative intervention is irreducibly personal, such that the decisions about and performance of operations are inseparable from the idiosyncrasies of the individual surgeon. Furthermore, there is a chasm of knowledge between the patient and surgeon that is difficult to cross. Hence, training in the discipline of surgery includes the inculcation of certain virtues and practices to safeguard against abuses of this relationship and to make sure that the best interests of the patient are prioritized. The stories in this issue are evidence that in contemporary practice this is not quite enough, as surgeons reflect on instances they felt were ethically challenging. Common themes include the difficulty in communicating surgical uncertainty, patient-surgeon relationships, ethical issues in surgical training, and the impact of the technological imperative on caring for dying patients.

  9. Transanal total mesorectal excision for rectal cancer: a preliminary report. (United States)

    Kang, Liang; Chen, Wen-Hao; Luo, Shuang-Ling; Luo, Yan-Xin; Liu, Zhi-Hua; Huang, Mei-Jin; Wang, Jian-Ping


    Currently, the majority cases of the novel down-to-up transanal total mesorectal excision (TaTME) were performed in a hybrid approach with conventional laparoscopic assistance because of less operative difficulty. However, although cases are limited, the successes of TaTME in a pure approach (without laparoscopic assistance) indicate that the costly and less mini-invasive hybrid TaTME could be potentially avoided. In the present single institutional, prospective study, we attempted to demonstrate the safety and feasibility of this approach in rectal cancer by evaluating the short-term results of our first 20 TaTME cases. For the majority of cases, we adopted a strategy that laparoscopic assistance was not introduced unless it was required during the planned pure TaTME procedure. A total of 20 patients (12 males and 8 females) were analyzed in this study, including 11 cases (55 %) of pure TaTME and 9 cases (45 %) of hybrid TaTME. Overall, the median operative time was 200 min (range 70-420), along with a median estimated blood loss of 50 ml (range 20-800). Morbidity rate was 20 % (one urethral injury, two urinary retentions, one anastomotic hemorrhage and one mild anastomotic leak). The median number of harvested lymph nodes was 12 (range 1-20). All specimens were intact in mesorectum without positive distal and circumferential resection margins. Among the 15 patients who were preoperatively scheduled to undertake pure TaTME, four patients (26.7 %) required converting to laparoscopic assistance. Moreover, among these 15 patients, the results of the comparative analysis between female and male subgroups favor the former, suggesting easier operation in them. This preliminary study demonstrates that TaTME in rectal cancer is safe and feasible. The strategy of not introducing laparoscopic assistance unless it is required while performing the planned pTaTME should be cautiously explored. Further studies with larger sample size and longer follow-up are warranted.

  10. Simple and surgical exodontia. (United States)

    DeBowes, Linda J


    Preemptive and postoperative pain management is part of patient care when performing extractions. Simple extractions can become complicated when tooth roots are fractured. Adequate lighting,magnification, and surgical techniques are important when per-forming surgical (complicated) extractions. Radiographs should be taken before extractions and also during the procedure to assist with difficult extractions. Adequate flap design and bone removal are necessary when performing surgical extractions. Complications, including ocular trauma, jaw fracture, and soft tissue trauma, are avoided or minimized with proper patient selection and technique.

  11. Specifically requesting surgical tattoo removal: are deep personal motivations involved? (United States)

    Koljonen, V; Kluger, N


      Motivations for tattoo removal include employment reasons, stigmata, changes in lifestyles or partners, incompatibility with present attitudes and values and clothing problems. Most studies on the motivations for tattoo removal have focused on patients seeking laser therapy. We hypothesized that patients seeking surgical tattoo removal would present with different motivations.   We analysed the characteristics and motivations of patients specifically requesting surgical tattoo removal.   We retrospectively reviewed the medical records of 16 patients in Helsinki, Finland, from 2005 to 2011. Demographic, clinical data, number of tattoos, location and size, time elapsed since tattooing, reason(s) for wanting surgical tattoo removal and surgical operations were analysed and compared with the other literature on tattoo removal.   Patients were mainly Caucasian females (ratio 3 : 1, median age of 26 years). Tattoos were all done by studio artists, most measured less than 30 cm², and were quite recent (median 5.3 years). Personal reasons accounted for 42.8% of all reasons, professional/social reasons for 37.5% and miscellaneous for 18.8%. Personal concerns were usually marital status changes, with few expressing dissatisfaction with the actual design of the tattoo. Tattoos were excised during a single procedure in 70% of the cases with only one case producing a hypertrophic scar.   Patients seeking surgical removal were aware of the limits and risks of the technique. They expressed intense personal reasons for wanting radical surgical removal. The possibility of surgical tattoo removal should be accessible to patients if the tattoo is small and discussion reveals strong personal motivation. © 2011 The Authors.

    Satava, R M


    Technological change, decreased financial support for medical education, and social oversight (in the form of the "To Err Is Human" report, HIPPA, and reduced work hours) are forcing a rethinking of the traditional model of surgical education to improve patient safety. New approaches to evaluating surgical competence, such as objective assessment, in combination with new technologies, such as the Internet and surgical simulators, provide the tools to effect a revolution in surgical education and training. Competency based upon quantifiable criteria measures must replace the traditional subjective assessment. The implementation requires accurately defining the elements of training, establishing new quantifiable metrics, stringently measuring performance against criterion, and reporting outcomes throughout the career of a surgeon.

  1. Laparoscopic adrenalectomy: Surgical techniques

    Directory of Open Access Journals (Sweden)

    Matthew J Mellon


    Full Text Available Since its first description in 1992, laparoscopic adrenalectomy has become the gold standard for the surgical treatment of most adrenal conditions. The benefits of a minimally invasive approach to adrenal resection such as decreased hospital stay, shorter recovery time and improved patient satisfaction are widely accepted. However, as this procedure becomes more widespread, critical steps of the operation must be maintained to ensure expected outcomes and success. This article reviews the surgical techniques for the laparoscopic adrenalectomy.

  2. The effect of excise tax increases on cigarette prices in South Africa. (United States)

    Linegar, Daniel J; van Walbeek, Corne


    The effectiveness of excise tax increases as a tool for reducing tobacco consumption depends largely on how the tax increases impact the retail price. We estimate this relationship in South Africa for 2001-2015. Statistics South Africa provided disaggregated cigarette price data, used in the calculation of the Consumers' Price Index. Data on the excise tax per cigarette were obtained from Budget Reviews prepared by the National Treasury of South Africa. Regression equations were estimated for each month. The month-on-month change in cigarette prices in February through April was regressed against March's excise tax change to estimate the pass-through coefficient. For the other 9 months, the month-on-month change in cigarette price was regressed against monthly dummy variables to determine the size of the non-tax-related price increase in each of these months. The analysis was performed in both nominal and real (inflation-adjusted) terms. Expressed in real terms, the excise tax was undershifted. A R1.00 (one rand) increase in the excise tax is associated with an increase in the retail price of cigarettes of R0.90 in the pre-2010 period, and R0.49 in the post-2010 period. In the pre-2010 period, the tobacco industry increased the retail price of cigarettes in July/August, independent of the excise tax increase. The discretionary July/August price increases largely disappeared after 2010, primarily because the market became more competitive. The degree of excise tax pass-through, and the magnitude of discretionary increases in cigarette prices, is significantly determined by the competitive environment in the cigarette market. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  3. Effects of early excision and grafting on cytokines and insulin resistance in burned rats. (United States)

    Chen, Xin-Long; Xia, Zhao-Fan; Ben, Dao-Feng; Duo, Wei


    Burn wound excision and grafting is a common clinical practice that decreases patient morbidity and mortality. It is not known, however, if the salutary effects of this procedure are related to effects on interleukin 6 (IL-6) and tumor necrosis factor (TNF-) α, and to reducing insulin resistance after burn. Sprague-Dawley rats were randomly divided into three groups: control, burn, burn ± excision groups. Rats in burn group were given a third-degree scald burn covering 30% total body surface area (TBSA) and no wound excision. Rats in burn ± excision group were subjected to a 30% third-degree burn followed by complete excision and allografting of the injury site within 15 min after burn. The rats in control group were treated in the same manner as the burn group, except that they were immersed in a room-temperature water. Glucose tolerance tests (GTT) were observed at 3 days after burn, euglycemic-hyperinsulinemic glucose clamps were performed at 4 days after burn and interleukin 6 (IL-6) and tumor necrosis factor (TNF-) α were determined after euglycemic-hyperinsulinemic glucose clamps. The levels of IL-6 and TNF-α increased after burn. Significant differences in GTT were observed between control and burn groups, and the rate of glucose infused measured in burned rats was significantly decreased compared with that in control at 4 days after burn. Early excision and grafting significantly decreased levels of IL-6 and TNF-α, and further reduced insulin resistance following thermal injury compared with burn group. Early excision and grafting appeared to have an effect on inflammatory mediators and further reduced insulin resistance induced by major burns. Copyright © 2010 Elsevier Ltd and ISBI.

    Full Text Available Introduction: Rhinophyma is a tumour-like enlargement of the skin of the nose, affecting dorsum nasi and the apex. While the aetiology is unknown, dermatosis rosacea can be indicated as one of the main causes. Rhinophyma is characterized by reddish, swollen bumpy surface of the nose, overgrowing of scar-like tissue and augmentation of the sebaceous glands. Epidemiologically, rhinophyma affects mainly men between the ages of 50 and 70. Purpose of the study: To present an overview of the disease based on our personal experience with the condition and the associated surgical treatment. Materials and methods: Our findings are based on the cases of four patients over a period of two years, diagnosed with the condition rhinophyma, who underwent surgical treatment in “Saint Marina” hospital. The excision was made using the “Coblator II system”. Results: Due to unresponsiveness to conventional treatment, surgical removal of the rhinophyma was necessary. Conclusion: Rhinophyma is a rare condition, causing discomfort to the patient and deforming the nose. Surgical intervention shows most effective results in the treatment of this disease.

  6. [Gastrointestinal stromal tumors: a series of 23 surgically treated cases]. (United States)

    D'Amato, A; Brini, A; Montesani, C; Pronio, A; Chessa, A; Manzi, F; Ribotta, G


    The recently introduced new nosological category, Gastro Intestinal Stromal Tumors, brought the Authors to a revision of their series and to a critical analysis of surgical behaviour for the treatment of that pathology. A series of 23 cases of GIST, observed between 1977 and 1999 has been taken into account. In the earlier cases, histopathological classification has been reviewed according to the most used criterions in international scientific literature. 17 of 23 observed tumors were located on the stomach, 4 on the duodenum and 2 on the jejunum. 20 of these cases derived from muscular tissue and 3 cases derived both from muscular and neural tissues. In 7 cases (30%) tumors were accidentally discovered during surgical intervention or diagnostic procedures for other causes. Surgical treatment was performed in all cases and consisted in 6 gastric resections, 14 gastric free-margin excisions, 2 duodenal resections and 1 jejunal resection. The follow-up (performed on 18 patients, with a minimum of 1 year, a maximum of 17 years and a median of 6 years) showed 2 deaths (11%) due to oncological causes, while 2 of the patients (11%) died for other causes. The only treatment for that group of tumors is, at the moment, surgery. Although that kind of neoplasms has mainly non-aggressive biological behaviour, a radical resection must be performed, due to the absence of macroscopic criterions to help distinguishing, during surgical intervention, aggressive tumors from non-aggressive ones.

  9. Hydatid disease of scapula and upper third of humerus treated by en bloc excision and fibular bone grafting

    Directory of Open Access Journals (Sweden)

    Chari P


    Full Text Available 35-year-old male patient presented with gradually increasing painful swelling of the right shoulder, which was incised and drained and wound persisted as a discharging sinus on the anterolateral aspect of the deltoid region with seropurulent discharge. A clinical diagnosis of tuberculosis of the shoulder was made. Plain skiagram of the right shoulder revealed multicystic lesion involving the entire scapula and upper third of the humerus with loss of joint space and pathological fracture at the junction of upper one-third and lower two-thirds of the humerus. A clinico-radiological diagnosis of hydatid disease was made. In view of the extensive involvement of the scapula with stiff shoulder and an active sinus, a two-stage surgical procedure was performed. Stage 1 consisted of en bloc excision of the scapula, upper half of the humerus and lateral end of the clavicle. Stage II surgery, consisting of fibular bone grafting. Tablet albendazole (400 mg, thrice daily was given as systemic scolicidal agent. This case is reported in view of it′s rarity and to highlight the management.

  10. The Perfect Total Mesorectal Excision Obviates the Need for Anything Else in the Management of Most Rectal Cancers. (United States)

    Heald, Richard John; Santiago, Ines; Pares, Oriol; Carvalho, Carlos; Figueiredo, Nuno


    This article discusses the local control of primary rectal cancer and its locoregional spread in the light of modern advances. In recent years, the use of neoadjuvant chemoradiation has spread widely. However, its true benefit is not always balanced with its morbidities. Often total mesorectal excision (TME) is the best option. We will discuss the indications for immediate surgery for chemoradiation in advance and the importance of a delay in the management plan. To understand this selection, it is mandatory to know the true extent of tissue at risk for tumor dissemination and spread. Considering that TME may be enough for many patients and that most local recurrences are failures of surgical technique we introduce a new concept of total mesorectal irradiation. This exploits the new reality that precise, focused neoadjuvant therapy can offer a better response with fewer complications. Together these important changes in cancer board (multidisciplinary team) planning can also offer selected patients complete control of their cancer with no need for surgery.

  11. Transparent crosslinked ultrashort peptide hydrogel dressing with high shape-fidelity accelerates healing of full-thickness excision wounds

    KAUST Repository

    Seow, Wei Yang


    Wound healing is a major burden of healthcare systems worldwide and hydrogel dressings offer a moist environment conducive to healing. We describe cysteine-containing ultrashort peptides that self-assemble spontaneously into hydrogels. After disulfide crosslinking, the optically-transparent hydrogels became significantly stiffer and exhibited high shape fidelity. The peptide sequence (LIVAGKC or LK6C) was then chosen for evaluation on mice with full-thickness excision wounds. Crosslinked LK6C hydrogels are handled easily with forceps during surgical procedures and offer an improvement over our earlier study of a non-crosslinked peptide hydrogel for burn wounds. LK6C showed low allergenic potential and failed to provoke any sensitivity when administered to guinea pigs in the Magnusson-Kligman maximization test. When applied topically as a dressing, the medium-infused LK6C hydrogel accelerated re-epithelialization compared to controls. The peptide hydrogel is thus safe for topical application and promotes a superior rate and quality of wound healing.

  12. Communicating the location of potential skin neoplasms for excision between the referring and the operating doctor--an audit of skin lesion referrals in Whanganui, New Zealand. (United States)

    Welsh, Fraser; Bullen, Naomi; Aiono, Semisi


    The importance of correctly defining the location of potential skin cancer when surgical treatment may be required is self-evident. Clear communication is essential if the professional diagnosing potential skin cancer is not the same professional providing treatment. We aimed to assess the nature of the localising information provided in referrals to the local anaesthetic skin lesion theatre in our institution. Information localising target lesions for new patients seen in our local anaesthetic skin excision theatre was recorded during a 2-month period April to May 2012 inclusive 100 patients were seen in our skin excision theatre during the study period; 16 patients were not able to identify the target skin lesion at the time they entered the operating theatre. The target lesion could not be determined from the referral text in 30/100 cases. Diagrams were provided in 19/100 cases. Photographs were provided in 3/100 cases. Pictorial and photographic means of communicating the location of suspicious lesions are under-utilised in our service. Relying on the patient or the referral text to correctly identify the lesion leaves considerable room for error. We suggest that photographic information for skin lesion referrals is adopted as a minimum standard.

  13. Comparison of the Limberg flap and bilateral gluteus maximus advancing flap following oblique excision for the treatment of pilonidal sinus disease. (United States)

    Yildar, Murat; Cavdar, Faruk


    This study was performed to compare the use of a bilateral gluteus maximus advancing flap (BGMAF) following oblique incision, which was recently described for the surgical treatment of sacrococcygeal pilonidal sinus (SPS) disease, with the widely used Limberg flap (LF) technique following a rhomboid incision. A total of 105 patients treated for SPS were evaluated retrospectively. The patients were evaluated in terms of their age, body mass index, symptoms, length of the operation, complications, postoperative hospital stay, time to return to work, postoperative cosmetic satisfaction and recurrence rate. Fifty-six of the patients were treated with BGMAF, while 49 were treated with LF. The mean follow-up was 20.5 ± 5.4 months. The mean length of the operation, hospital stay and time to return to work were shorter, while the cosmetic satisfaction score was higher in the BGMAF group compared to the LF group. There was no statistically significant difference between the groups for the other criteria. The BGMAF appears to be superior to the LF in terms of the length of the operation, time to return to work and degree of cosmetic satisfaction. It is preferable for sinuses not to require wide excision, while the LF is more appropriate for sinuses with a large post-excision defect.

  14. Surgical Outcomes of Urinary Tract Deep Infiltrating Endometriosis. (United States)

    Darwish, Basma; Stochino-Loi, Emanuela; Pasquier, Geoffroy; Dugardin, Fabrice; Defortescu, Guillaume; Abo, Carole; Roman, Horace

    To report the outcomes of surgical management of urinary tract endometriosis. Retrospective study based on prospectively recorded data (NCT02294825) (Canadian Task Force classification II-3). University tertiary referral center. Eighty-one women treated for urinary tract endometriosis between July 2009 and December 2015 were included, including 39 with bladder endometriosis, 31 with ureteral endometriosis, and 11 with both ureteral and bladder endometriosis. Owing to bilateral ureteral localization in 8 women, 50 different ureteral procedures were recorded. Procedures performed included resection of bladder endometriosis nodules, advanced ureterolysis, ureteral resection followed by end-to-end anastomosis, and ureteroneocystostomy. The main outcome measure was the outcome of the surgical management of urinary tract endometriosis. Fifty women presented with deep infiltrating endometriosis (DIE) of the bladder and underwent either full-thickness excision of the nodule (70%) or excision of the bladder wall without opening of the bladder (30%). Ureteral lesions were treated by ureterolysis in 78% of the patients and by primary segmental resection in 22%. No patient required nephrectomy. Histological analysis revealed intrinsic ureteral endometriosis in 54.5% of cases. Clavien-Dindo grade III complications were present in 16% of the patients who underwent surgery for ureteral nodules and in 8% of those who underwent surgery for bladder endometriosis. Overall delayed postoperative outcomes were favorable regarding urinary symptoms and fertility. Patients were followed up for a minimum of 12 months and a maximum of 7 years postoperatively, with no recorded recurrences. Surgical outcomes of urinary tract endometriosis are generally satisfactory; however, the risk of postoperative complications should be taken into consideration. Therefore, all such procedures should be managed by an experienced multidisciplinary team. Copyright © 2017 AAGL. Published by Elsevier Inc

  15. Generation of transgene-free mouse induced pluripotent stem cells using an excisable lentiviral system. (United States)

    Varga, E; Nemes, C; Davis, R P; Ujhelly, O; Klincumhom, N; Polgar, Z; Muenthaisong, S; Pirity, M K; Dinnyes, A


    One goal of research using induced pluripotent stem cell (iPSC) is to generate patient-specific cells which can be used to obtain multiple types of differentiated cells as disease models. Minimally or non-integrating methods to deliver the reprogramming genes are considered to be the best but they may be inefficient. Lentiviral delivery is currently among the most efficient methods but it integrates transgenes into the genome, which may affect the behavior of the iPSC if integration occurs into an important locus. Here we designed a polycistronic lentiviral construct containing four pluripotency genes with an EGFP selection marker. The cassette was excisable with the Cre-loxP system making possible the removal of the integrated transgenes from the genome. Mouse embryonic fibroblasts were reprogrammed using this viral system, rapidly resulting in large number of iPSC colonies. Based on the lowest EGFP expression level, one parental line was chosen for excision. Introduction of the Cre recombinase resulted in transgene-free iPSC subclones. The effect of the transgenes was assessed by comparing the parental iPSC with two of its transgene-free subclones. Both excised and non-excised iPSCs expressed standard pluripotency markers. The subclones obtained after Cre recombination were capable of differentiation in vitro, in contrast to the parental, non-excised cells and formed germ-line competent chimeras in vivo.

  16. Circumareolar incision-subdermal tunneling dissection for excision of multiple breast fibroadenomata

    Directory of Open Access Journals (Sweden)

    S O Agodirin


    Full Text Available Excision of multiple fibroadenomas (MF in separate breast quadrants presents difficulties of number and location of incision(s and extent of tissue dissection and may be associated with more complications and poorer cosmetic outcome. This is a report of excision of MF in multiple quadrants of the breast using a modification of subcutaneous dissection technique dubbed the circumareolar incision and subdermal tunneling (CAST dissection. After exposure of the superficial fascia with circumareolar incision, subdermal cone-wise dissection was made to allow mobilization of the segment bearing the lump(s. The lump(s were enucleated and removed. MF were removed from four breasts in three young unmarried females. The first patient had multiple adenomas removed from three quadrants of both breasts: 14 on the right and six on the left. The second patient had excision of three lumps in three separate quadrants, and the third patient had excision of two lumps in two separate quadrants. All patients had edema and bruising. One breast had wound infection and dehiscence. There were no skin necrosis, no nipple loss, and no breast distortion. All ensuing scars were camouflaged. CAST dissection was used for excision of MF in multiple quadrants of the breast with preservation of excellent cosmetic outcome of a single circumareolar incision.

    Oncoplastic surgery (OPS) consists of breast-conserving surgery (BCS) that allows for oncologically safe breast conservation and breast remodeling, thus reducing postoperative deformities. The purpose of the present study was to identify factors determining the risk of re-excision and complications after OPS. A retrospective analysis was conducted on patients who underwent OPS between 2009 and 2013, regardless of whether neoadjuvant chemotherapy was administered. Clinical and pathological factors were evaluated. Recursive partitioning analysis (RPA) was used to build regression trees for the prediction of re-excision. Amongst the 129 patients treated by OPS procedures, 30.3% required re-excision. Predictive factors for re-excision were: being overweight (p=0.02), the presence of microcalcifications on mammography (p=0.003), and tumor multifocality (p=0.03). The RPA identified five terminal nodes based on microcalcifications on mammography, being overweight and the presence of ductal carcinoma in situ. Another model included minimal invasive margins (p<0.001), being overweight (p=0.02) and the presence of microcalcifications (p=0.01) on mammography yielded a model with an area under the receiver operating characteristic curve of 0.875. Microcalcifications, tumor multifocality and being overweight were the factors identified as predictors of re-excision after OPS. These factors can serve as decisional tools before surgery.

  18. The Relationship between Tax Rate, Penalty Rate, Tax Fairness and Excise Duty Non-compliance.

    Directory of Open Access Journals (Sweden)

    Sinnasamy Perabavathi


    Full Text Available The rise of indirect tax non-compliance by taxpayers became the main concern of most of the tax authorities around the globe. In Malaysia, non complaince such as smuggling and illegal trade activities by importers involving cigarettes, liquor and imported vehicles bound under Excise Act 1976 have caused revenue losses in monetary and non-monetary aspects. Therefore, the objective of this study is to examine the relationship of tax rate, penalty rate and tax fairness of excise duty non-compliance. This study uses the Deterrence Theory as a basis theory to investigate the phenomenon of excise duty non complaince. A total of 500 excise duty offenders throughout Malaysia responded to the survey. The model was empirically tested by using Partial Least Squares (PLS with disproportionate stratified random sampling technique. The results indicated that the perception of tax rate and penalty rate are positively related while tax fairness is negatively related to excise duty non-compliance among importers.

    To evaluate the safety and feasibility of laparoscopic complete mesocolic excision via combined medial and cranial approaches with three-dimensional visualization around the gastrocolic trunk and middle colic vessels for transverse colon cancer. We evaluated prospectively collected data of 30 consecutive patients who underwent laparoscopic complete mesocolic excision between January 2010 and December 2015, 6 of whom we excluded, leaving 24 for the analysis. We assessed the completeness of excision, operative data, pathological findings, length of large bowel resected, complications, length of hospital stay, and oncological outcomes. Complete mesocolic excision completeness was graded as the mesocolic and intramesocolic planes in 21 and 3 patients, respectively. Eleven, two, eight, and three patients had T1, T2, T3, and T4a tumors, respectively; none had lymph node metastases. A mean of 18.3 lymph nodes was retrieved, and a mean of 5.4 lymph nodes was retrieved around the origin of the MCV. The mean large bowel length was 21.9 cm, operative time 274 min, intraoperative blood loss 41 mL, and length of hospital stay 15 days. There were no intraoperative and two postoperative complications. Our procedure for laparoscopic complete mesocolic excision via combined medial and cranial approaches is safe and feasible for transverse colon cancer.

  20. Excision-repair of γ-ray damaged thymine in bacterial and mammalian systems

    Hariharan, P.V.; Remsen, J.F.; Cerutti, P.A.


    The selective excision of products of the 5,6-dihydroxy-dihydrothymine type (t') for γ-irradiated or OsO 4 -oxidized DNA or synthetic poly [d(A-T)] was observed with crude extracts of Escherichia coli and isolated nuclei from human carcinoma HeLa S-3 cells and Chinese hamster ovary cells. The results with E. coli extracts allow the following conclusion: The uvrA-gene product is not required for t' excision; radiation-induced strand breakage is not required for product excision; experiments with extracts of E. coli polAexl showed that the 5' → 3' exonuclease associated with polymerase I is responsible for the removal of t'; experiments with extracts of E. coli endo I lig 4 and the ligase inhibitor nicotinamide mononucleotide showed that polynucleotide ligase accomplishes the last strand resealing step in the excision-repair of t'. Isolated nuclei from HeLa and Chinese hamster ovary cells possess the necessary enzymes for the selective excision of t' from γ-irradiated or osmium tetroxide oxidized DNA. Approximately 25 to 35 percent of the products were removed from DNA within 60 min. Unspecific DNA degradation was very low. Radiation-induced strand breakage is not required for product removal

  1. Inhibition of excision repair of DNA in u.v.-irradiated Escherichia coli by phenethyl alcohol

    International Nuclear Information System (INIS)

    Tachibana, A.; Yonei, S.


    Membrane-specific drugs such as procaine and chlorpromazine have been shown to inhibit excision repair of DNA in u.v.-irradiated E. coli. One possible mechanism is that, if association of DNA with the cell membrane is essential for excision repair, this process may be susceptible to drugs affecting the structure of cell membranes. We examined the effect of phenethyl alcohol, which is a membrane-specific drug and known to dissociate the DNA-membrane complex, on excision repair of DNA in u.v.-irradiated E. coli cells. The cells were irradiated with u.v. light and then held at 30 0 C in buffer (liquid-holding) in the presence or absence of phenethyl alcohol. It was found that phenethyl alcohol inhibits the liquid-holding recovery in both wild-type and recA strains, corresponding to its dissociating action on the DNA-membrane complex. Thus, the association of DNA with cell membrane is an important factor for excision repair in E. coli. Procaine did not show the dissociating effect, suggesting that at least two different mechanisms are responsible for the involvement of cell membrane in excision repair of DNA in E. coli. (author)

Surgery planning and simulation include construction of 3D surface models from Cone-beam CT (CBCT), dynamic cephalometry, semi-automatic mirroring, interactive cutting of bone and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intra-operative guidance. The system provides further intra-operative assistance with the help of a computer display showing jaw positions and 3D positioning guides updated in real-time during the surgical procedure. The CAS system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training and assessing the difficulties of the surgical procedures prior to the surgery. CAS has the potential to make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases.

  4. Effects of hyperthermia on radiation-induced chromosome breakage and loss in excision repair deficient Drosophila melanogaster

    International Nuclear Information System (INIS)

    Mittler, S.


    Hyperthermia increased radiosensitivity with respect to γ-ray induced chromosome loss and breakage in all stages of spermatogenesis in the wild type Oregon R strain of Drosophila melanogaster, whereas hyperthermia increased radiosensitivity to a lesser extent in cn mus(2) 201sup(D1), an excision repair mutant with 0 per cent excision capacity and in mus(3) 308sup(D1), a strain with 24 per cent excision capacity. The differences in hyperthermia-induced radiation sensitivity between the excision repair mutants and the wild strain may be due to the hyperthermia affecting the excision repair mechanism, suggesting that one of the possible mechanisms involved in hyperthermia-increased radiosensitivity is an effect on excision repair.

  7. Hemipelvectomy with laparoscopic abdominoperineal excision for epithelioid sarcoma treatment

    Directory of Open Access Journals (Sweden)

    Daniel Paulino Santana


    Full Text Available The epithelioid sarcoma (ES is an unusual variant of the sarcoma, not reaching 1% of all soft tissue sarcomas. Initially reported in 1970, it has a more aggressive variant, which was classified as the “proximal-type” in 1997. These are aggressive tumors with high rates of distant metastasis and local relapses. Isolated radio and chemotherapy responses are poor and free-margin surgical resection is the treatment of choice.This is the case report of a 25-year-old male patient diagnosed with “proximal-type” ES in the perineal region. He underwent surgical resection in another institution and was later admitted to our institution with local recurrence with rectal and left thigh muscle invasion. Neoadjuvant radio-chemotherapy was performed, followed by laparoscopic abdominoperineal rectal resection and partial left hemipelvectomy associated with left lower-limb amputation. The patient had no postoperative complications and is currently undergoing outpatient follow-up. The anatomopathological analysis showed tumor-free margins.The “proximal-type” ES is a rare soft-tissue sarcoma subtype. High local recurrence, as well as the metastasis rates, makes its treatment a challenging task. Resumo: O sarcoma epitelióide (SE é um subtipo incomum de sarcoma, não chegando a 1% dos sarcomas de partes moles. Foi inicialmente descrito em 1970, sendo que em 1997 uma variante mais agressiva foi classificada como “tipo proximal”. São tumores agressivos, com altas taxas de metástases e recidiva local, com resposta pobre à quimioterapia e radioterapia isoladas. A ressecção cirúrgica com margens livres é o tratamento padrão.Apresentamos o caso de um paciente de 25 anos com SE tipo proximal avançado em região perineal, submetido a ressecção em outro serviço, evoluindo com recidiva local com invasão do canal anal e musculatura da coxa esquerda. Foi realizado tratamento radioquimioterápico neoadjuvante seguido de ressecção cirúrgica com

  8. Comparison of the effect of nalidixic acid and thymine deprivation on excision repair in Escherichia coli

    International Nuclear Information System (INIS)

    Masek, F.; Slezarikova, V.; Sedliakova, M.


    A difference was found in the extent of inhibition of thymine dimers (TT) excision in ultraviolet (UV) irradiated cells of E. coli after preirradiation depression of protein and DNA syntheses induced by a simultaneous removal of essential amino acids (AA - ) and thymine (T - ) or by the removal of essential amino acids and the addition of nalidixic acid (NAL + ). The difference was observed in both E. coli B/r Hcr + and E. coli K12 SR20 uvr + cells. The depression of DNA synthesis by nalidixic acid as an exogenous agent inhibited TT excision to a lower degree than the depression of DNA synthesis by thymine starvation. The extent of TT excision had no appreciable effect on the restoration of the sedimentation profile of a newly synthesized DNA nor on UV resistance of cells during dark repair. A DNA molecule having the size of a molecule of nonirradiated cells became synthesized while TT were still present in the DNA. (author)

    Nørholm Morten HH


    Full Text Available Abstract Background The combined use of restriction enzymes with PCR has revolutionized molecular cloning, but is inherently restricted by the content of the manipulated DNA sequences. Uracil-excision based cloning is ligase and sequence independent and allows seamless fusion of multiple DNA sequences in simple one-tube reactions, with higher accuracy than overlapping PCR. Results Here, the addition of a highly efficient DNA polymerase and a low-background-, large-insertion- compatible site-directed mutagenesis protocol is described, largely expanding the versatility of uracil-excision DNA engineering. Conclusions The different uracil-excision based molecular tools that have been developed in an open-source fashion, constitute a comprehensive, yet simple and inexpensive toolkit for any need in molecular cloning.

  11. Carpal boss: destabilization of the third carpometacarpal joint after a wedge excision. (United States)

    Citteur, J M; Ritt, M J; Bos, K E


    In a standard carpal boss procedure, the dorsal ligament of the involved carpometacarpal joint is cut in the process of performing a wedge excision. We studied the effect of such a dorsal ligament sectioning on the joint between the capitate and middle metacarpal bone in ten fresh-frozen wrist specimens. The passive range of motion of this joint was measured with the joint loaded into flexion and extension and in the unloaded neutral position. After the dorsal ligament of the carpometacarpal joint was cut, simulating a dorsal wedge excision, the passive range of motion was measured again. Analysis indicated that this simulated wedge excision approximately doubled the passive range of motion of the carpometacarpal joint. This study shows that such a procedure disturbs the normal anatomy and creates instability of the involved joint.

  12. Plantar fascia release and calcaneal spur excision for sub-calcaneal heel pain. (United States)

    Torudom, Yingyong


    Aim of this study was to evaluate the results of open plantar fascia release and calcaneal spur excision in patients with plantar fasciitis. The author studied retrospectively the results in 16 patients who had been treated with open plantar fascia release and calcaneal spur excision from 2002 to 2008. Two patients were men and fourteen were women. Their mean age was 43.3 years (39 to 52). Based on visual analog scale the results were pain free in 12 feet and some pain in four. There are two patients with superficial skin infection which can be manage with local wound care and oral antibiotic. We conclude that open plantar fascia release and calcaneal spur excision can relieve pain in patients who resist conservative treatment.

    Chakravarti, Arnab; Willett, Christopher G.; Shellito, Paul; Kaufman, Donald; Daley, William J.


    PURPOSE: the long-term outcomes of patients undergoing local excision with or without pelvic irradiation were examined to define the role of adjuvant irradiation following local excision of T1 and T2 rectal cancers. METHODS: From January 1966 to January 1997, 114 patients underwent local excision for rectal cancer. Fifty-nine patients underwent local excision alone, and 55 patients received adjuvant pelvic irradiation (45 Gy to 65.8 Gy)+/-concurrent 5-fluorouracil chemotherapy. Outcome was assessed by treatment, stage, and pathologic features of tumor grade and lymphatic/venous vessel involvement. RESULTS: Of the 114 patients treated by local excision, 90 had T1/T2 tumors. The 5-year actuarial local control (LC) and recurrence-free survival (RFS) of these 90 patients are shown (with numbers of patients at risk at 5 years) in the table below. The 5-year actuarial local control and recurrence-free survival (RFS) for T1/T2 patients treated by local excision alone was 85% and 77%, respectively. The corresponding values for patients undergoing local excision and adjuvant irradiation alone were 88% and 78%, respectively. All 20 patients treated by adjuvant chemoradiation achieved 5-year actuarial local control and had a recurrence-free survival of 88%. The improved outcomes in the adjuvant radiation group become more impressive when the higher T stage distribution of this group is considered. Fifty-five percent of the group receiving adjuvant radiation were stage T2 compared to only 14% of patients treated by local excision alone. Subgroup analysis was performed on those features recognized as poor prognostic factors including poorly differentiated histology and lymphatic vascular invasion. Patients in the local excision alone group with one or more adverse pathologic features had reduced rates of local control compared to those with the absence of such features (38% vs. 91%, respectively, p=0.02). In comparison, the 5 patients with poor prognostic features treated by

  14. Reconstructive Surgery of the Upper Eyelid Using the Residual Tarsus after Excision of Sebaceous Gland Carcinoma

    Tatsuya Yunoki


    Full Text Available Purpose: To report a successful eyelid reconstruction performed using the residual tarsus after excision of a sebaceous gland carcinoma. Case Report: An 86-year-old woman presented with a sebaceous gland carcinoma of the upper eyelid margin. After excision of the tumor, she underwent reconstructive surgery of the superior eyelid performed using the residual tarsus. Because the tumor was localized on the upper lid margin, a tarsus of about 4–5 mm in height remained after the excision; we therefore used the residual tarsus to reconstruct the upper eyelid. No functional or cosmetic problems arose as a result of this method. Conclusions: Reconstructive surgery of the upper eyelid using the residual tarsus may be a viable option provided that surgeons can ensure a sufficient safety margin, and that more than 4 mm of the tarsus remains.

  15. 'Batman excision' of ventral skin in hypospadias repair, clue to aesthetic repair (point of technique). (United States)

    Hoebeke, P B; De Kuyper, P; Van Laecke, E


    In the hypospadiac penis the ventral skin is poorly developed, while dorsal skin is redundant. The classical Byars' flaps are a way to use the excess dorsal skin to cover the penile shaft. The appearance after Byars' flaps however is not natural. We use a more natural looking skin allocation with superior aesthetic results. The clue in this reconstruction is an inverted triangle shaped excision of ventral skin expanding over the edges of the hooded prepuce (which makes it look like Batman). After excision of the ventral skin it is possible to close the penile skin in the midline, thus mimicking the natural raphe. In case of preputial reconstruction the excised ventral skin makes the prepuce look more natural. The trend of further refining aesthetic appearance of the hypospadiac penis often neglects the penile skin reconstruction. A technique is presented by which the total penile appearances after surgery ameliorates due to better skin reconstruction.

  16. Structures of Reverse Transcriptase Pre- and Post-Excision Complexes Shed New Light on HIV-1 AZT Resistance

    Directory of Open Access Journals (Sweden)

    Walter A. Scott


    Full Text Available HIV-1 resistance to 3'-azido-2',3'-deoxythymidine (AZT, zidovudine results from mutations in reverse transcriptase that increase the ability of the enzyme to excise AZT-monophosphate after it has been incorporated. Crystal structures of complexes of wild type and mutant reverse transcriptase with double-stranded DNA with or without the excision product, AZT adenosine dinucleoside tetraphosphate (AZTppppA, have recently been reported [1]. The excision-enhancing mutations dramatically change the way the enzyme interacts with the excision product.

  17. Green and non-green callus induction from excised rice (Oryza sativa) embryos: effects of exogenous plant growth regulators (United States)

    Kim, D.; Brock, T. G.; Kaufman, P. B.


    Calli were induced either from excised rice embryos or from whole seeds in the presence of 1 to 5 mg l-1 NAA. After 12 days of culture, calli were induced only from excised rice embryos. We found that excised embryos accumulated NAA up to 6 times higher concentration than did whole seeds. In the presence of 1 to 5 mg l-1 NAA and 2 to 10 mg l-1 kinetin, chlorophyllous calli were induced from excised rice embryos. Chlorophyll contents in the callus tissue increased with increasing kinetin concentration while percent callus induction decreased. The total chlorophyll content was linearly correlated with the ratio of kinetin to NAA in the medium.

  18. Surgical resection of low-grade gliomas in eloquent areas with the guidance of the preoperative functional magnetic resonance imaging and craniometric points

    Directory of Open Access Journals (Sweden)

    Ahmed Abdullah


    Full Text Available Objectives: Surgical resection of low-grade gliomas (LGGs in eloquent areas is one of the challenges in neurosurgery, using assistant tools to facilitate effective excision with minimal postoperative neurological deficits has been previously discussed (awake craniotomy and intraoperative cortical stimulation; however, these tools could have their own limitations thus implementation of a simple and effective technique that can guide to safe excision is needed in many situations. Materials and Methods: The authors conducted a retrospective analysis of a prospectively collected data of 76 consecutive surgical cases of LGGs of these 21 cases were situated in eloquent areas. Preoperative functional magnetic resonance imaging (fMRI, pre- and post-operative MRI with volumetric analysis of the tumor size was conducted, and intraoperative determination of the craniometric points related to the tumor (navigation guided in 10 cases were studied to evaluate the effectiveness of the aforementioned tools in safe excision of the aforementioned tumors. Results: Total-near total excision in 14 (66.67% subtotal in 6 (28.57%, and biopsy in 1 case (4.57%. In long-term follow–up, only one case experienced persistent dysphasia. Conclusion: In spite of its simplicity, the identification of the safe anatomical landmarks guided by the preoperative fMRI is a useful technique that serves in safe excision of LGGs in eloquent areas. Such technique can replace intraoperative evoked potentials or the awake craniotomy in most of the cases. However, navigation-guided excision might be crucial in deeply seated and large tumors to allow safe and radical excision.

  19. Contemporary Review of Grafting Techniques for the Surgical Treatment of Peyronie's Disease. (United States)

    Hatzichristodoulou, Georgios; Osmonov, Daniar; Kübler, Hubert; Hellstrom, Wayne J G; Yafi, Faysal A


    Peyronie's disease (PD) is a benign fibrotic disorder of the tunica albuginea of the penis, which can cause penile pain, curvature, shortening, erectile dysfunction, and psychological distress. Surgery is indicated when penile curvature prevents satisfactory sexual intercourse. Plaque incision or excision with grafting has been suggested as an option in patients with a penile curvature greater than 60°, a shortened penis, and/or an hourglass or complex deformity. To provide an overview of recent studies reporting outcomes of grafting techniques and to report advances in the development of new grafting materials for PD surgery. A literature review was performed through PubMed from 2011 through 2016 regarding grafting techniques for PD. Key words used for the search were grafting techniques, grafts, graft materials, Peyronie's disease, surgical outcomes, and surgical therapy. To report on novel and promising graft materials for PD and to discuss surgical techniques, outcomes, and limitations. Discussed outcomes include postoperative penile straightening, shortening, erectile function, glans sensation, and patient satisfaction. Various surgical techniques and grafting materials can be used for the coverage of the tunica albuginea defect after partial plaque excision or incision. Autologous and non-autologous grafts have been used in this setting. A major advantage of the available "off-the-shelf" grafts is that they do not require donor site harvesting, thus decreasing morbidity and operative time. Tissue-engineered grafts represent the future, but more research is needed to further improve surgical handling and postoperative outcomes. Patients opting for grafting techniques should have sufficient erectile rigidity preoperatively. Surgeon experience, careful patient selection, patient preference, and type of penile deformity affect the choice of graft and surgical approach used.

  20. Large anterior orbital cyst as a late complication of chalazion surgical drainage. (United States)

    Alsuhaibani, A H; Al-Faky, Y H


    To present four patients who developed large cystic lesions attached to the tarsal plate at the site of previously drained chalazion. Medical records for all patients who developed cystic lesion as a complication of chalazion surgery were retrospectively reviewed for clinical and radiological findings, treatment provided, histopathological findings, and complications. Four patients (one male and three females) with a mean age of 22 years (range, 11-36 years) were enrolled in the study. A history of chalazion surgery was present in all patients at the same site of the cyst attachment to the tarsal plate. The mean interval between the presentation with the cystic lesion and the chalazion surgery was 13 weeks (range, 6-24 weeks). All patients were treated with surgical excision of the cysts, along with local triamcinolone injection. Histopathological findings of the excised cysts were consistent with chalazion. There was no evidence of recurrence or other complication observed during the follow-up visits (the minimum follow-up duration was 6 months). Anterior orbital cystic formation (prolapsed chalazion) may occur as a late complication of chalazion surgery. Surgical excision along with steroid injection was effective to manage this rare complication among our patients.
