    We aimed to investigate the role of surgical excision in treating granulomatous lobular mastitis. We performed a retrospective chart review of patients with granulomatous lobular mastitis treated from March 2008 to March 2014. We analyzed clinical features and therapeutic modalities and compared the patient outcomes based on treatment. During the study period, a total of 34 patients were diagnosed with granulomatous lobular mastitis and treated. Initial treatments included wide excision (18), oral steroids after incision and drainage (14), and antibiotic therapy (2). The patients receiving only antibiotic therapy showed no improvement after 1 month and wide excision was then performed. Wide excision resulted in nine case of delayed wound healing with fistula. These patients were treated with oral steroids for 1.5-5 months, with subsequent improvement. Overall, 11 out of 20 patients who had underwent wide excision showed improvement without additional treatment. Fourteen patients who had initially received oral steroids for 1 to 6 months (average, 2.8 months) after incision and drainage showed complete remission. During the median follow-up period with 45.5 months (range, 22-98 months), six patients (17.6%) experienced recurrence. Wide excision group experienced recurrence in five (25%) and steroid and drainage group experienced recurrence in one (7.1%). All six recurrences responded to additional steroid therapy for average 3.5 months. Most wide excision group left extensive breast scarring with deformation that was not in steroid and drainage group. Wide excision resulted high recurrence than steroid and drainage group and left extensive scarring. Steroid therapy with or without abscess drainage may be the first choice of treatment for majority cases with granulomatous lobular mastitis.

    Full Text Available BackgroundBecause there are numerous methods for reconstruction of the lower lip, it is not easy to choose the optimal method. In choosing the surgical method for lower lip reconstruction, we obtained acceptable outcomes based on our treatment strategy, which included either a barrel-shaped excision or the Webster modification of the Bernard operation. We report on the surgical outcomes based on our treatment strategy.MethodsThis study included 26 patients who underwent lower lip reconstructive surgery from September 1996 to September 2010. The operation was done using either a barrel-shaped excision or the Webster modification, considering the location of the defect, the size of the defect, and the amount of residual tissue on the lateral side of the vermilion after excision.ResultsIn our series, 3 patients underwent a single barrel-shaped excision, and nine patients underwent a double barrel-shaped excision. In addition, the unilateral Webster modification was performed on in 6 patients, and there were eight cases of bilateral Webster modification. All of the patients except one were satisfied with the postoperative shape of the lip. In one case both recurrence and dehiscence occurred. One patient had a good postoperative lip shape, but had difficulty wearing a denture, and also underwent commissuroplasty. Furthermore, there were two patients who complained of drooling, and 4 with paresthesia.ConclusionsA soft tissue defect resulting from wide excision of a lower lip malignancy can be successfully reconstructed using only one of two surgical methods: the barrel-shaped excision or the Webster modification of the Bernard operation.

    The best surgical treatment modalities for subungual squamous cell carcinoma (SUSCC) without bone invasion need to be determined. The limited available data on Mohs micrographic surgery do not demonstrate its use as a standard procedure. A previous study in a limited series of patients has shown that wide surgical excision of the nail unit was associated with a low rate of recurrence. To confirm the efficiency of wide surgical excision of the nail unit with full-thickness skin graft reconstruction on a series of patients with SUSCC with an extended follow-up and to evaluate short- and long-term postoperative morbidity and patient satisfaction. A consecutive series of 55 patients with biopsy-proven SUSCC without bone invasion treated by wide surgical excision of the nail unit followed by full-thickness skin graft reconstruction from January 1, 2000, to August 31, 2012 were included. After a minimum follow-up of 5 years, the recurrences were collected from the referring physicians. Statistical analysis was conducted from January 1 to June 30, 2016. Demographic data, pathologic characteristics of tumors, postoperative follow-up, and recurrences were collected from medical records. Patients' satisfaction with surgery, quality of life, and delayed postoperative morbidity (functional outcome and sensory disorders) were assessed from a questionnaire mailed to patients and physicians. Among the 55 patients (23 women and 32 men; mean age, 64 years), the mean follow-up was 6.6 years (range, 5.0-11.2 years), with a minimum follow-up of 5 years. Fifty-two questionnaires (95%) were returned. Two recurrences were observed. Minor early postoperative complications, such as graft infection and delayed wound healing, were seen in 6 patients; 8 patients experienced severe pain. Late postoperative complications included hypersensitivity to mechanical shocks (39 of 51 patients [76%]), mildly increased sensitivity to cold (38 of 51 patients [75%]), loss of fine touch sensation (17 of 35

    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.

    2011-01-01

    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

    Surgery is the only curative treatment for removal of the persistent sinus tracts in the skin that are characteristic of severe hidradenitis suppurativa (HS). Complete resection of the affected tissue by wide excision is currently regarded as the preferred surgical technique in these cases. However, relatively large amounts of healthy tissue are removed with this method and suitable skin-tissue-saving techniques aiming at creating less-extensive surgical defects are therefore needed in severe HS. We describe a skin-tissue-saving surgical technique for HS Hurley stage II-III disease: the Skin-Tissue-sparing Excision with Electrosurgical Peeling (STEEP) procedure. In contrast to wide excisions that generally reach into the deep subcutaneous fat, the fat is maximally spared with the STEEP procedure by performing successive tangential excisions of lesional tissue until the epithelialized bottom of the sinus tracts has been reached. From here, secondary intention healing can occur. In addition, fibrotic tissue is completely removed in the same manner as this also serves as a source of recurrence. This tissue-sparing technique results in low recurrence rates, high patient satisfaction with relatively short healing times and favourable cosmetic outcomes without contractures. © 2014 European Academy of Dermatology and Venereology.

    Complete mesocolic excision provides a correct anatomical plane for colon cancer surgery. However, manifestation of the surgical plane during laparoscopic complete mesocolic excision versus in computed tomography images remains to be examined. Patients who underwent laparoscopic complete mesocolic excision for right-sided colon cancer underwent an abdominal computed tomography scan. The spatial relationship of the intraoperative surgical planes were examined, and then computed tomography reconstruction methods were applied. The resulting images were analyzed. In 44 right-sided colon cancer patients, the surgical plane for laparoscopic complete mesocolic excision was found to be composed of three surgical planes that were identified by computed tomography imaging with cross-sectional multiplanar reconstruction, maximum intensity projection, and volume reconstruction. For the operations performed, the mean bleeding volume was 73±32.3 ml and the mean number of harvested lymph nodes was 22±9.7. The follow-up period ranged from 6-40 months (mean 21.2), and only two patients had distant metastases. The laparoscopic complete mesocolic excision surgical plane for right-sided colon cancer is composed of three surgical planes. When these surgical planes were identified, laparoscopic complete mesocolic excision was a safe and effective procedure for the resection of colon cancer.

    Here, we present the clinical presentation and surgical outcomes of women with symptomatic urethral prolapse presenting to our institution over 20 years, and seek to provide treatment recommendations for management of symptomatic urethral prolapse and caruncle. A retrospective review of medical records from female patients who underwent surgery for symptomatic urethral prolapse from June 1995 to August 2015 was performed. Surgical technique consisted of a four-quadrant excisional approach for repair of urethral prolapse. A total of 26 patients were identified with a mean age of 38.8 years (range 3-81). The most common presentations were vaginal bleeding, hematuria, pain, and dysuria. All patients underwent surgical excision of urethral prolapse via a standard approach. Follow-up data was available in 24 patients. Six patients experienced temporary postoperative bleeding, and one patient required placement of a Foley catheter for tamponade. One patient experienced temporary postoperative urinary retention requiring Foley catheter placement. Three patients had visible recurrence of urethral prolapse, for which one later underwent re-excision. Surgical excision of urethral prolapse is a reasonable treatment option in patients who have tried conservative management without relief, as well as in those who present with severe symptoms. Possible complications following excision include postoperative bleeding and recurrence, and patients must be counseled accordingly. In this work, we propose a treatment algorithm for symptomatic urethral prolapse. © 2017 Wiley Periodicals, Inc.

    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.

    We previously described an endoscopic-assisted transvaginal mesh excision technique. This study compares surgical outcomes after transvaginal mesh excision vs endoscopic-assisted transvaginal mesh excision. In addition, we reviewed our postoperative outcomes with excision via laparotomy. This was an inclusive retrospective analysis of patients presenting to our institution from 1997 to 2006 for surgical management of vaginal erosion of permanent mesh after sacrocolpopexy. Three techniques were utilized: transvaginal, endoscopic-assisted transvaginal, and laparotomy. For the patients undergoing transvaginal excision, data recorded included number and type of excisions performed, number of prior excisions performed at outside facilities, intraoperative and postoperative complications (including blood transfusions, pelvic abscess, or bowel complications), use of postoperative antibiotics, persistent symptoms of vaginal bleeding and discharge at follow-up, and demographic characteristics. The intraoperative and postoperative complications and the postoperative symptoms were recorded for the laparotomy cases. Thirty-one patients underwent transvaginal mesh excision during this time period: 17 endoscopic-assisted transvaginal and 14 transvaginal without endoscope assistance. In addition, a total of 7 patients underwent abdominal excision via laparotomy. Comparison of the 2 vaginal methods revealed no difference in the demographics or success rate, with success defined as no symptoms at follow-up. Endoscopic-assisted transvaginal excision was successful in 7 of 17 patients and transvaginal without endoscopic assistance in 9 of 13 patients (1 patient excluded for lack of follow-up data) for a total vaginal success rate of 53.3%. No intraoperative and only minor postoperative complications occurred with either vaginal method. Three patients underwent 3 vaginal attempts to achieve complete symptom resolution. The average follow-up time for the entire vaginal group was 14

    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.

    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.

    Full Text Available Achieving a level of technical skill and confidence in surgical operations is the main goal of plastic surgical training. Operating rooms were accepted as the practical teaching venues of the traditional apprenticeship model. However, increased patient population, time, and ethical and legal considerations made preoperation room practical work a must for plastic surgical training. There are several plastic surgical teaching models and simulators which are very useful in preoperation room practical training and the evaluation of plastic surgery residents. The full thickness skin with its vascular network excised in abdominoplasty procedures is an easily obtainable real human tissue which could be used as a training model in plastic surgery.

    A retrospective study was carried out to compare the overall standard of surgical excision of malignant melanomas (MMs) between general practitioners (GPs) and hospital specialists before and after the introduction of the UK melanoma guidelines between 1989 and 2006. In total, 213 melanoma excision reports were examined and surgical excision margins recorded. The results showed a significant difference in the rate of adequate surgical excision margins (at all levels of Breslow thickness) between GPs and hospital specialists, with hospital specialists excising melanomas with safe surgical excision margins at a significantly higher rate compared with GPs. Since the introduction of the guidelines in 2002, GPs showed a significant improvement in the completeness of melanoma excision but remained poor at prehistology diagnosis and in particular at taking adequate excision margins. Implementation of the guidelines has not produced significant improvements in adequacy of excision margins in both primary and secondary care. The results show that hospital specialists maintained a high standard of prehistological diagnosis and completeness of excision throughout the time of the study, performing at a significantly higher standard compared with GPs. Our conclusions concur with the UK melanoma guidelines and the National Institute for Health and Clinical Excellence guidelines, which suggest that lesions suspicious for melanoma should be urgently referred to a dermatologist or plastic surgeon for surgical excision and should not be surgically excised in primary care, particularly if lesions have a Breslow thickness > 2 mm. We suggest that the new guidelines need to be more aggressively implemented in primary care and guidance introduced to improve the accuracy of diagnosis, with better training provided for GPs.

    Full Text Available Purpose: The aim of the study is to improve operative speed and precision of haemangiomas excision. Methods: Case-report: haemangioma is a common affection of the 8% of the population during the neonatal period. In complicated cases and involution sequelae surgical treatment is the first choice. The Authors propose a surgical refinement to prevent intraoperative bleeding. Methods: several suture stitches were placed around the hemangioma. The edges of the lesion became more defined, thus allowing accurate excision. Results and Conclusions: Haemangiomas are characterized by rich blood supply. Surgery is often hindered by massive bleeding and Temporary placement of full-thickness sutures, surrounding the hemangioma, allowed a noticeable improvement in hemostasis precision and greater definition of the margins of the hemangioma.

    Lower local recurrence rates and better overall survival are associated with complete mesocolic excision with central vascular ligation for treatment of colon cancer. To accomplish this, surgeons need to pay special attention to the surgical anatomical planes and vascular anatomy of the colon. However, surgical education in this area has been neglected. The aim of this study is to define the correct surgical anatomical planes for complete mesocolic excision with central vascular ligation and to demonstrate the correct dissection technique for protecting anatomical structures. Macroscopic and microscopic surgical dissections were performed on 12 cadavers in the anatomy laboratory and on autopsy specimens. The dissections were recorded as video clips. Dissections were performed in accordance with the complete mesocolic excision technique on 10 male and 2 female cadavers. Vascular structures, autonomic nerves, and related fascias were shown. Within each step of the surgical procedure, important anatomical structures were displayed on still images captured from videos by animations. Three crucial steps for complete mesocolic excision with central vascular ligation are demonstrated on the cadavers: 1) full mobilization of the superior mesenteric root following the embryological planes between the visceral and the parietal fascias; 2) mobilization of the mesocolon from the duodenum and the pancreas and identification of vascular structures, especially the veins around the pancreas; and 3) central vascular ligation of the colonic vessels at their origin, taking into account the vascular variations within the mesocolonic vessels and the autonomic nerves around the superior mesenteric artery. The limitation of this study was the number of the cadavers used. Successful complete mesocolic excision with central vascular ligation depends on an accurate knowledge of the surgical anatomical planes and the vascular anatomy of the colon.

    Full Text Available We report a case of isolated ossification of iliopsoas with ankylosis of the left hip in a 27-year-old female. The patient was diagnosed to have Moyamoya disease, a rare chronic occlusive disorder of cerebrovascular circulation following an acute onset of hemiplegia. The patient presented 9 months later to us with ankylosis of left hip which was successfully treated by surgical excision of the heterotopic bone and there was no recurrence at the end of 5 years. A review of literature failed to reveal a similar case with isolated and complete ossification of iliopsoas muscle associated with Moyamoya disease which required surgical intervention. Surgical excision resulted in dramatic improvement in the quality of life. Surgical excision of neurogenic type of heterotopic ossification is a very successful procedure and timely intervention after maturity of mass is very important to prevent the onset of secondary complications and to avoid recurrence.

    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)

    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.

    Despite the standard management of non-palpable breast cancer (needle core biopsy diagnostic, accurate preoperative localization), there are differences in some cases between the malignant histo-pathological finding in diagnostic biopsy results and negative histo-pathological finding after surgical excision. The aim of this study is to evaluate this incidence and classifying them under three category: failure of surgical excision after preoperative identification; removal of the tumor was already completed by percutaneous biopsy; percutaneous biopsy true false positive. We conducted a study based on prospective database, all patients included in this study had partial mastectomy for ductal carcinoma in-situ or invasive cancer which was diagnosed by needle core biopsy and normal/benign after surgery. Regarding the partial mastectomy, 1863 was performed in the last three years in our center. Thirty-seven patients (2%) correspond our study criteria. After discussion of cases in our multidisciplinary reunion, 6 patients (16%) were considered as failure of surgical excision, 26 patients (70%) as true removal of the whole lesion in the core, and 5 patients (13%) as true false-positive cores. This is the first study witch investigate all factors that influence the results of negative final histo-pathological finding of surgical excision of the tumor after malignant diagnostic needle core biopsy. This rare situation need a multidisciplinary meeting to analyse all the steps of management and to determine causes of those false results and try to find adequate management to solve this problem.

  12. 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

    2013-01-01

    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....

    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.

    Non-atypical papillomas (NAPs) diagnosed on core needle biopsy (CNB) frequently undergo surgical excision due to highly variable upstaging rates. The purpose of this study is to document our dual-institution upgrade rates of NAPs diagnosed on core needle biopsy and review the upgrade rates reported in the literature. Following IRB approval, CNB results from Duke University (7/1/2004-6/30/2014) and the University of North Carolina Chapel Hill (1/1/04-6/30/2013) were reviewed to identify non-atypical papillomas. All cases with surgical excision or 2 years of imaging follow up were included. In addition, a literature review identified 60 published studies on upgrades of NAPs diagnosed at CNB. Cases in our cohort and the published literature were reviewed for confounding factors: [1] missing radiologic-pathologic concordance and/or discordance, [2] papillomas included with high-risk lesions, [3] high risk lesions counted as upgrades, [4] review by a nonspecialized breast pathologist, and [5] cancer incidentally detected. Of the 388 CNBs in our dual-institution cohort, 136 (35%) patients underwent surgical excision and 252 (65%) patients had imaging follow up. After controlling for confounders, no cancers (0/388) were found at surgical excision or during follow up imaging. The literature review upstaging rate was 4.0% (166/4157) but 1.8% (4/227) after excluding studies with confounders. The combined upstaging rate from the literature and this study was 0.6% (4/615). The upstaging rate for CNB diagnosed NAPs was 0% in our cohort and 0.6% overall after adjusting for confounders. This low rate does not warrant reflexive surgical excision and diagnostic imaging follow up should be discretionary. Copyright © 2018 Elsevier Inc. All rights reserved.

    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.

    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.

    To compare the frequency of recurrence following aspiration and injection of steroid versus surgical excision in the treatment of wrist ganglion. Study Design: Randomized controlled trial.Place and Duration of Study: General surgical department, Combined Military Hospital, Rawalpindi, Pakistan, from Jan 2010 to Dec 2010. Material and Methods: Sixty patients of clinically diagnosed wrist ganglia were randomized into groups 'A' and 'B' with 30 patients in each group. After approval by the hospital ethical committee, patients in group 'A' were subjected to aspiration and injection of methyl-prednisolone acetate 40 mg/ml and those in group 'B' underwent surgical excision of the ganglion. Patients were explained the procedure they were subjected to and they were also counselled about the risk of recurrence after a particular procedure and after that informed written consent was obtained from them. Patients were followed up at intervals of 2 weeks, 6 weeks, 3 months and 6 months after the procedure to look for recurrence in both groups. Results: On follow up at 6 months, 12 (40%) patients in group A while only 2 (6.66%) patients in group B had recurrence of the ganglion. No complications were noted. This difference was found to be statistically significant (p=0.0023). Conclusion: Recurrence of wrist ganglion is considerably less in patients treated with surgical excision and should be preferred over aspiration and steroid injection. (author)

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

    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.

    Tumour size and the quality of its complete surgical removal are the main prognostic factors in rectal cancer treatment. The number of postoperative local recurrences depends on whether the mesorectum has been completely removed - total mesorectal excision (TME) - and whether tumour-free resection margins have been achieved. The surgery itself and its quality depend on the accuracy of preoperative diagnosis and detection of risk areas in the rectum and mesorectum, on the surgeons skills, and finally on pathological assessment evaluating whether complete tumour excision has been accomplished including circumferential margins of the tumour, and whether mesorectal excision is complete. The aim of our study was to implement and standardize a new method of evaluation of the quality of the surgical procedure - TME - in rectal cancer treatment using an assessment of its circumferential margins (CRO) and completeness of the excision. The study consisted of two parts. The first, multi-centre retrospective phase with 288 patients analysed individual partial parameters of the diagnosis, operations and histological examinations of the rectal cancer. Critical points were identified and a unified follow-up protocol was prepared. In the second, prospective part of this study 600 patients were monitored parametrically focusing on the quality of the TME and its effect on the oncological treatment results. The proportion of patients with restaging following neoadjuvant therapy increased from 60.0% to 81.7% based on preoperative diagnosis. The number of specimens missing an assessment of the mesorectal excision quality decreased from 52.9% in the retrospective part of to the study to 22.8% in the prospective part. The proportion of actually complete TMEs rose from 22.6% to 26.0%, and that of nearly complete TMEs from 10.1% to 24.0%. The introduction of parametric monitoring into routine clinical practice improved the quality of pre-treatment and preoperative diagnosis, examination of

    Congenital rectal duplication cyst is a rare entity treated with surgical excision. Without treatment, a rectal duplication cyst may cause a variety of complications, most notably, transforming into a malignancy. We report on a 7-week-old girl who was found to have a rectal duplication cyst. The rectal duplication cyst was successfully excised laparoscopically. Rectal duplication cysts are rare alimentary tract anomalies generally discovered during childhood. Complications include symptoms arising from the cyst and the possibility of malignant degeneration. They are typically managed by surgical excision.

    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.

    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

    2007-01-01

    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.

    Full Text Available Abstract Coexistence of coronary artery disease and cancer with both requiring surgical treatment at the same time is rare. A 52 year male undergoing elective coronary artery bypass grafting was incidentally discovered to have a large soft tissue mass of variable consistency with cartilaginous elements arising from the right costal margin and adjoining ribs by a broad attachment and protruding into right pleural cavity. Frozen section suggested it to be either a chondrosarcoma or a teratoma. A wide excision of the mass with the adjoining muscle and periosteum along with quadruple coronary artery bypass grafting was done. This report is unusual on account of a being the first reported case in world literature of concomitant excision of chondrosarcoma and coronary artery bypass grafting and b the conservative management of the incidentally discovered chondrosarcoma by wide excision rather than chest wall resection with no local recurrence to date. Pathology of chondrosarcoma, in particular, and various management strategies when coronary artery disease and cancer coexist, in general, is discussed.

    2014-11-01

    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

    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.

    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.

    Complications of synthetic midurethral sling surgery include bladder outlet obstruction, mesh extrusion, and vaginal pain. A treatment of these complications is transvaginal mesh removal. The objectives of this video are to present cases of complications after sling placement and describe techniques to help with successful sling removal. Three patients are presented in this video. One experienced urinary hesitancy and was found to have bladder outlet obstruction on urodynamic study. The second patient presented to the clinic with diminished force of stream and significant dyspareunia. The last patient presented with mesh extrusion. After discussion of management options, all three patients wished to pursue transvaginal sling excision. All patients had successful removal of a portion of their synthetic midurethral sling. This video presents techniques to aide with dissection, mesh excision and prevention of further mesh complications. These include using an individualized surgical technique based on patient presentation and surgeon expertise, planning surgical incisions based on where mesh can be identified or palpated, using a cystoscope sheath or urethral dilator to identify any bladder outlet obstruction, and using a knife blade to identify mesh from surrounding tissue. Sling excision can be successfully performed with careful surgical technique and dissection.

    Full Text Available Mucoceles are nonneoplastic cystic lesions of major and minor salivary glands which result from the accumulation of mucus. These lesions are most commonly seen in children. Though usually these lesions can be treated by local surgical excision, in our case, to avoid intraoperative surgical complications like bleeding and edema and to enable better healing, excision was done using a diode laser in the wavelength of 940 nm.

    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.

    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. 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. 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. Surgical management with complete surgical excision is essential to achieve optimal EFS in patients with BI-ALCL. © 2015 by American Society of Clinical Oncology.

    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

  20. Aggressive surgical management of craniopharyngiomas

    Full Text Available Surgical treatment of craniopharyngiomas is challenging and despite advancements it continues to pose a challenge. Proponents of subtotal resection in conjunction with radiotherapy argue that this less aggressive approach can yield appropriate results with the lower morbidity. On the contrary, other argument is that gross total resection is superior. Though surgical management of craniopharyngioma is challenging due to its location and important surrounding neurovascular structures, optimal surgical results can be expected following radical surgical excision. Radical excision of craniopharyngiomas is associated with excellent long-term recurrence free survival. Radiation induced long-term complications can be altogether avoided by excising these tumors completely.

  1. 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

    2016-01-01

    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.

    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.

    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.

    Full Text Available Background: Mucocele is a common benign neoplasm of oral soft tissues and the most common after fibroma. It generally occurs in the lower lip and its treatment includes excision of cyst and the responsible salivary gland, in order to prevent recurrences. Aims: To evaluate the capability of three different lasers in performing the excision of labial mucocele with two different techniques. Materials and Methods: In the presented cases, excision was performed using two different techniques (circumferential incision technique and mucosal preservation technique and three different laser wavelengths (Er,Cr:YSGG 2780 nm, diode 808 nm, and KTP 532 nm. Results: All the tested lasers, regardless of wavelength, showed many advantages (bloodless surgical field, no postoperative pain, relative speed, and easy execution. The most useful surgical technique depends on clinical features of the lesion. Conclusion: Tested lasers, with both techniques, are helpful in the management of labial mucocele.

    The optimal surgical approach (wide local excision (WLE) vs. Mohs micrographic surgery (MOHS)) for treating Merkel cell carcinoma (MCC) is yet to be determined. To compare survival outcomes in patients with early stage MCC treated with MOHS versus WLE. A retrospective review of all cases in the National Cancer Data Base (NCDB) of MCC of clinical Stage I-II MCC treated with WLE or MOHS was performed. 1,795 cases of Stage I-II MCC were identified who underwent WLE (N=1,685) or MOHS (N=110). There was no difference in residual tumor on surgical margins between the two treatment groups (p=0.588). On multivariate analysis, there was no difference in overall survival between the treatment modalities (adjusted HR 1.02; 95% CI 0.72-1.45, p=0.897). There was no difference in overall survival between the two groups on propensity score matched analysis. Disease specific survival was not reported as this data in not available in the NCDB. MOHS appears to be as effective as WLE in treating early stage MCC. Copyright © 2018. Published by Elsevier Inc.

    To compare the efficacy and tolerability of surgical excision and radiotherapy with those of cryotherapy and intralesional steroid treatment of keloids. Twenty-six patients with a total of 76 keloids were enrolled in this study. Nineteen patients with 44 keloids underwent surgical excision combined with immediate 12-Gy irradiation (group A) while the remaining 9 patients with 32 keloids received multiple sessions of intralesional steroid treatment after cryotherapy which continued until flattening of lesion(s) occurred (group B). Two patients were included in both treatment groups. All patients were followed up at regular intervals for at least 1 year. In both treatment groups, keloids responded well without any major side effect. While patients of group A were all satisfied, those of group B (with a mean number of treatment sessions of 5.84 +/- 2.51) experienced more side effects, a more prolonged course, a higher recurrence rate and less satisfaction. This study showed that surgery plus immediate postoperative irradiation was an effective and relatively safe choice for treatment of keloids. Although cryotherapy combined with intralesional steroids was associated with more side effects and higher relapse rates, it could be a good choice for small and newly formed keloids.

    To compare the efficacy of carbon dioxide (CO(2)) laser with cutting diathermy as a cutting device in surgical excision of early carcinoma tongue. Experimental study. Combined Military Hospital (CMH), Rawalpindi and CMH, Lahore, from July 2008 to July 2011. Twenty two biopsy proven cases of T(1) and early T(2) squamous cell carcinoma of tongue were divided in two equal groups of 11 each labeled as A and B. Tumor was excised by CO(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's exact test. P-value of < 0.05 was considered significant. 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 T(1) while 7/11 (63.6%) had T(2) stage tumor. In group B, 5/11 (45.4%) were having T1 and 6/11 (54.5%) were having stage T(2) 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). Early carcinoma tongue is better removed by laser than electrocautery in terms of postoperative morbidity, per-operative blood loss, postoperative pain and oral swelling.

    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.

    Full Text Available Purpose. The purpose of this study was to compare the surgical and pathological variables which impact rate of re-excision following breast conserving therapy (BCS with or without concurrent additional margin excision (AM. Methods. The pathology database was queried for all patients with DCIS from January 2004 to September 2008. Pathologic assessment included volume of excision, subtype, size, distance from margin, grade, necrosis, multifocality, calcifications, and ER/PR status. Results. 405 cases were identified and 201 underwent BCS, 151-BCS-AM, and 53-mastectomy. Among the 201 BCS patients, 190 underwent re-excision for close or involved margins. 129 of these were treated with BCS and 61 with BCS-AM (P<.0001. The incidence of residual DCIS in the re-excision specimens was 32% (n=65 for BCS and 22% (n=33 for BCS-AM (P<.05. For both the BCS and the BCS-AM cohorts, volume of tissue excised is inversely correlated to the rate of re-excision (P=.0284. Multifocality (P=.0002 and ER status (P=.0382 were also significant predictors for rate of re-excision and variation in surgical technique was insignificant. Conclusions. The rate of positive margins, re-excision, and residual disease was significantly higher in patients with lower volume of excision. The performance of concurrent additional margin excision increases the efficacy of BCS for DCIS.

    Breast cancer is the most common form of cancer and the second leading cause of death amongst women in Europe. Amongst five invasive cancers per 1000 women detected in screening, 2.7 were localization (WGL). With the clinical setting shifting towards earlier non-palpable breast lesions being detected through screening, we investigated whether the current standard in assisting surgical excision of these lesions, WGL, yields the best therapeutic outcome for women with breast cancer. To assess the therapeutic outcomes of any new form of guided surgical intervention for non-palpable breast lesions against wire-guided localization, the current gold standard. We searched the Cochrane Breast Cancer Group's (CBCG) Specialized Register, MEDLINE (via PubMed), the Cochrane Central Register of Controlled Trials (CENTRAL), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) search portal from the earliest available date up to 30 March 2015. We also handsearched recent conference proceedings and sought information from experts in the field. Two review authors, BC and RJ, independently screened by title and abstract the studies we had identified through the search strategy; when this was inconclusive, they examined the full-text article for inclusion. We resolved any discrepancies regarding eligibility by discussion with a third review author, RA. Three review authors, BC, JW, and RJ, independently extracted data using a standardized data sheet. We performed all analyses using Review Manager (RevMan) or the R meta package, and in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. We reported results via a graphical assessment using forest plots showing the study estimates. We considered and discussed additional subgroup and sensitivity analyses. We identified 11 randomized controlled trials (RCTs) that met the inclusion criteria of this Cochrane review and included eight trials in the meta-analyses. Six RCTs

    Full Text Available BackgroundFacial capillary malformations (CMs rarely recede; they often become darker and raised in proportion to their growth. These malformations may hypertrophy in adulthood, resulting in increased disfigurement and dysfunction. Laser treatment is considered a first-line therapy for focal CMs, but thick wide lesions, which are accompanied by hypertrophy and have a well-circumscribed nodularity, may be treated with surgical excision and reconstruction.MethodsWe retrospectively reviewed the records of 25 consecutive patients who had undergone complete or partial excisions of facial capillary malformations in our unit. After the excisions, the defects that encompassed their facial aesthetic units were subsequently covered by various methods, including primary closures, local flaps, expanded flaps, split-thickness skin grafts, and full thickness skin grafts.ResultsThe data demonstrated satisfactory results and reliability. Our patients were treated without significant complications, and all of the patients were moderately or fully satisfied with the outcome of their surgeries.ConclusionsAmong the many reconstructive options for adult patients with facial capillary malformations, thick split-thickness skin grafts can be a good choice for the coverage of widely excised wounds.

    Full Text Available Basal cell carcinoma (BCC is the most common skin cancer worldwide. The WHO has defined it as “a locally invasive, slowly spreading tumor which rarely metastasizes, arising in the epidermis or hair follicles and in which the peripheral cells usually simulate the basal cells of the epidermis.” Here we discuss the management of BCCs of central face with surgical excision and reconstruction with forehead flap as single modality treatment. Material and Methods. This is a retrospective review of 50 patients who underwent surgical excision of BCC involving the facial region followed by primary reconstruction using forehead flaps at a single institution. There were 20 males and 30 females, mean age of 59 years. Results. No recurrence at primary site was observed during the follow-up of 1–4 yrs. There was no ectropion or exposure sequela. However, epiphora was evident. Size of lesions ranged from 2 to 6 cm. Keloid formation was seen in 2 (4% patients. Functional and cosmetic outcomes were satisfactory. Conclusion. For the face, the best reconstructive effort eventually fails in the face of tumor recurrence. The forehead flap represents one of the best methods for repair of extensive facial defects. Complete tumor extirpation, the primary event, is the key.

    Gynecomastia is a common aesthetic problem faced by men with reported incidence as high as 65% with serious psychosocial impact. Although various techniques of liposculpture combined with glandular excision is the standard of treatment, many of the glandular excision techniques have inherent limitations and complications such as leaving a long scar, long operative time, contour abnormalities, and increased risk of hematoma. Here, we describe an innovative "the orange peel excision of gland (OPEG) technique" which overcomes these limitations with excellent cosmetic results. A total of 38 breasts were operated in 20 patients (18 bilateral and 2 unilateral). All the patients underwent suction-assisted liposuction and glandular excision under general anesthesia by our OPEG technique. The average operative time per breast was 60 minutes. One patient had a small hematoma which did not require evacuation. The patient satisfaction rate was 95%. The technique has reduced operative time and avoids residual gland and hematoma with excellent aesthetic outcome.

    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)

    The purpose of this study is to describe an endoscope-assisted surgical technique for the excision of branchial cleft cysts and compare it to the standard approach. Retrospective case series review. Twenty-seven cases described as branchial cleft excisions performed by a single surgeon at one academic medical center were identified between 2007 and 2014. Twenty-five cases (8 endoscopic, 17 standard approach) were included in the study. Cases were excluded if final pathology was malignant. Patient charts were reviewed, and two techniques were compared through analysis of incision size, operative time, and surgical outcomes. This study showed that the length of incision required for the endoscopic approach (mean = 2.13 ± 0.23) was significantly less than that of the standard approach (mean = 4.10 ± 1.46, P = 0.008) despite the fact that there was no significant difference in cyst size between the two groups (P = 0.09). The other variables examined, including operative time and surgical outcomes, were not significantly different between the two groups. This transcervical endoscope-assisted approach to branchial cleft cyst excision is a viable option for uncomplicated cases. It provides better cosmetic results than the standard approach and does not negatively affect outcomes, increase operative time, or result in recurrence. 4.

    2015-05-01

    Full Text Available Surgical treatment of gynecomastia could present unique challenges for the plastic surgeon. Achieving a good balance between effectiveness of the selected approach and the satisfactory aesthetic outcome often is a difficult endeavor. Optimal surgical treatment involves a combination of liposuction and direct excision. In the present study the charts of 11 patients treated with suction-assisted liposuction and direct surgical excision were retrospectively reviewed; a special emphasis is placed on the surgical technique. The mean follow-up period of the patients was 11.6 months. No infection, hematoma, nipple-areola complex necrosis and nipple retraction was encountered in this series. The combined surgical treatment of gynecomastia has shown to be a reliable technique in both small and moderate breast enlargement including those with skin excess.

    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.

    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.

    The elliptical (fusiform) excision is a basic tool of cutaneous surgery. To assess the design, functionality, ease of construction, and aesthetic outcomes of the ellipse. A systematic review of elliptical designs and their site-specific benefits and limitations. In particular, we consider the (1). context of prevailing relaxed skin tension lines and tissue laxity; and (2). removal of the smallest possible amount of tissue around the lesion and in the "dog-ears." Attention is focused on intuitive methods that can be reproducibly planned and executed. Elliptical variations are easily designed and can be adapted to many situations. The eccentric parallelogram excision is offered as a new technique that minimizes notching and focal tension in the center of an elliptical closure. Conclusion The elliptical (fusiform) excision is an efficient, elegant, and versatile technique that will remain a mainstay of the cutaneous surgical armamentarium.

    This study was a multicenter evaluation of the SAVI SCOUT(®) breast localization and surgical guidance system using micro-impulse radar technology for the removal of nonpalpable breast lesions. The study was designed to validate the results of a recent 50-patient pilot study in a larger multi-institution trial. The primary endpoints were the rates of successful reflector placement, localization, and removal. This multicenter, prospective trial enrolled patients scheduled to have excisional biopsy or breast-conserving surgery of a nonpalpable breast lesion. From March to November 2015, 154 patients were consented and evaluated by 20 radiologists and 16 surgeons at 11 participating centers. Patients had SCOUT(®) reflectors placed up to 7 days before surgery, and placement was confirmed by mammography or ultrasonography. Implanted reflectors were detected by the SCOUT(®) handpiece and console. Presence of the reflector in the excised surgical specimen was confirmed radiographically, and specimens were sent for routine pathology. SCOUT(®) reflectors were successfully placed in 153 of 154 patients. In one case, the reflector was placed at a distance from the target that required a wire to be placed. All 154 lesions and reflectors were successfully removed during surgery. For 101 patients with a preoperative diagnosis of cancer, 86 (85.1 %) had clear margins, and 17 (16.8 %) patients required margin reexcision. SCOUT(®) provides a reliable and effective alternative method for the localization and surgical excision of nonpalpable breast lesions using no wires or radioactive materials, with excellent patient, radiologist, and surgeon acceptance.

    Basal-cell carcinoma is the most common form of skin cancer and its incidence is increasing worldwide. We aimed to assess the effectiveness of imiquimod cream versus surgical excision in patients with low-risk basal-cell carcinoma. We did a multicentre, parallel-group, pragmatic, non-inferiority, randomised controlled trial at 12 centres in the UK, in which patients were recruited between June 19, 2003, and Feb 22, 2007, with 3 year follow-up from June 26, 2006, to May 26, 2010. Participants of any age were eligible if they had histologically confirmed primary nodular or superficial basal-cell carcinoma at low-risk sites. We excluded patients with morphoeic or recurrent basal-cell carcinoma and those with Gorlin syndrome. Participants were randomly assigned (1:1) via computer-generated blocked randomisation, stratified by centre and tumour type, to receive either imiquimod 5% cream once daily for 6 weeks (superficial) or 12 weeks (nodular), or surgical excision with a 4 mm margin. The randomisation sequence was concealed from study investigators. Because of the nature of the interventions, masking of participants was not possible and masking of outcome assessors was only partly possible. The trial statistician was masked to allocation until all analyses had been done. The primary outcome was the proportion of participants with clinical success, defined as absence of initial treatment failure or signs of recurrence at 3 years from start of treatment. We used a prespecified non-inferiority margin of a relative risk (RR) of 0.87. Analysis was by a modified intention-to-treat population and per protocol. This study is registered as an International Standard Randomised Controlled Trial (ISRCTN48755084), and with ClinicalTrials.gov, number NCT00066872. 501 participants were randomly assigned to the imiquimod group (n=254) or the surgical excision group (n=247). At year 3, 401 (80%) patients were included in the modified intention-to-treat group. At 3 years, 178 (84%) of

    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.

    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 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.

  5. Excision Hemorrhoidectomy: New Methods to Improve the Outcomes of an Old Technique

    2016-02-01

    Full Text Available Context Hemorrhoidal disease is the most common anorectal disorder that requires surgical intervention. Hemorrhoids require treatment when they result in symptoms such as bleeding or prolapse. Surgical intervention is indicated for significant prolapse, and a number of accepted and viable methods are available for treating prolapsing hemorrhoids that do not reduce spontaneously (Grade III and IV. Excision hemorrhoidectomy remains the gold standard treatment for Grade III and IV hemorrhoids despite great interest in alternative procedures such as stapled hemorrhoidopexy and Doppler-guided hemorrhoidal artery ligation with mucopexy. A large body of evidence demonstrates that excision hemorrhoidectomy is an effective, safe, and affordable procedure. Nevertheless, the main drawback of excision hemorrhoidectomy remains its notorious association with significant postoperative pain. Evidence Acquisition A comprehensive literature search was conducted through MEDLINE and the Cochrane database of systematic reviews. Only prospective case-controlled studies, review articles, and meta-analyses were considered. Results Many strategies have been put forward in the literature to address the issue of pain after excision hemorrhoidectomy. These strategies can be broadly categorized into surgical techniques (e.g., LigaSure hemorrhoidectomy and pharmacological adjuncts (e.g., intradermal methylene blue and chemical sphincterotomy with glyceryl trinitrate ointment. In recent years, meta-analyses and randomized controlled trials have been performed to evaluate their effects. Conclusions This article evaluates the evidence behind these strategies and outlines the new methods available to improve the outcomes of an old technique.

    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.

    Pilonidal sinus (PS) is an infectious and inflammatory disease of sacrococcygeal region. Current methods include; surgical excision with/without suturing the defect, rhomboid excision and flap and chemical substance application. In this study, crystallized phenol application was compared to excision and primary closure. This retrospective study included pediatric patients with PS who were treated with excision and primer closure technique and phenol application. The patients' medical data were analyzed retrospectively. This study included 117 patients with PS. There were 52 girls (44%) and 65 boys (56%). Mean age of children was 15.6 (12-20) years. Excision and primary closure were applied to 77 patients (66%) and phenol was applied to 40 patients (34%). The children in phenol group were discharged on the operation day; mean hospitalization time in the excision and primary closure group was 2.7 (1-14) days. Mean follow up was 44.6 (8-82) months for primary excision and closure group and 8.1 (1-19) months for phenol group. Although many surgical and non-surgical treatment modalities have been described for PS, the optimal one remains unknown. Limited with the retrospective nature of the data, crystallized phenol application seems a feasible minimal invasive alternative to primary closure of PS with lower recurrence and complication rates in children.

    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

    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

    Branchial cleft anomalies are well described, with the second arch anomaly being the commonest. Following surgical excision, recurrence occurs in 2 to 22 per cent of cases, and is believed to be due largely to incomplete resection. This report aims to describe a simple surgical technique for treatment of second branchial cleft sinus in the older paediatric age group and adults. An 11-year-old girl underwent surgical excision of a second branchial sinus. Prior to surgery, she was assessed by means of an imaging sonogram, and by direct methylene blue dye injection into the sinus on the operating table, followed by insertion of a metallic probe. Dissection was of the 'step ladder' incision type, but the incision was completed via an oropharyngeal approach. Histological examination of the lesion after excision established the diagnosis. No recurrence had been observed at the time of writing. Although they are congenital lesions, second branchial cleft abnormalities usually present in the older paediatric age group or even in adulthood. In the case reported, a simple combined approach ensured completeness of resection.

    Although oncoplastic breast surgery is used to resect larger tumors with lower re-excision rates compared to standard wide local excision (sWLE), criticisms of oncoplastic surgery include a longer-albeit, well concealed-scar, longer operating time and hospital stay, and increased risk of complications. Round block technique has been reported to be very suitable for patients with relatively smaller breasts and minimal ptosis. We aim to determine if round block technique will result in operative parameters comparable with sWLE. Breast cancer patients who underwent a round block procedure from 1st May 2014 to 31st January 2016 were included in the study. These patients were then matched for the type of axillary procedure, on a one to one basis, with breast cancer patients who had undergone sWLE from 1st August 2011 to 31st January 2016. The operative parameters between the 2 groups were compared. 22 patients were included in the study. Patient demographics and histologic parameters were similar in the 2 groups. No complications were reported in either group. The mean operating time was 122 and 114 minutes in the round block and sWLE groups, respectively (P=0.64). Length of stay was similar in the 2 groups (P=0.11). Round block patients had better cosmesis and lower re-excision rates. A higher rate of recurrence was observed in the sWLE group. The round block technique has comparable operative parameters to sWLE with no evidence of increased complications. Lower re-excision rate and better cosmesis were observed in the round block patients suggesting that the round block technique is not only comparable in general, but may have advantages to sWLE in selected cases.

    2002-01-01

    Full Text Available In the second half of the 20 century, echosonography has been used in many medical specialties. In 1992 and 1993 highfrequencies echosonography was used in the examination of irritant and allergic skin lesions in order to examine the effects of different therapeuthical agents on the skin lesions [1-4]. Hoffmann used highfrequencies echosonography in the examination of healing of skin lesions [3]. By their incidence skin tumors are the largest group of newly discovered tumors, and their usual location is on the face [5-7]. By clinical examination it is not possible to precisely determine the depth of tumor border; therefore, the radically performed surgical excision is the only correct surgical treatment. The aim of this study was to estimate the results of preoperatively performed high frequencies echosonography in order to reduce the number of incorrectly performed surgical excisions of skin tumors. The group was composed of 40 patients with 45 tumors, who first underwent echosonographic diagnostic procedure (20 MHz, Hadsund electronic, Hadsund Technology, Denmark and then surgical excision; patients in control group (45 patients with 45 tumors were only subjected to surgical excision. Excised tumors were then pathohistologically analyzed, and measurements of tumor depth progression were performed. Margins of pathohistological specimen were controlled for the presence of tumor cells. Results of measurements of tumor depth obtained by echosonography and pathohistological measurements were compared. By Jate's modification of c2 test results regarding correct and incorrect surgical excision in patients and control group were compared. By linear regression analysis results of tumor depth obtained by echosonographic and pathohistologic examinations were compared. Hypoechogen zone echosonographic results were used like criteria for tumor expansion. Results of tumor depth measurements are presented in Table 1. Linear regression analysis showed (R = 0

    2011-01-01

    Hemorrhoids are common human afflictions known since the dawn of history. Surgical management of this condition has made tremendous progress from complex ligation and excision procedures in the past to simpler techniques that allow the patient to return to normal life within a short period. Newer techniques try to improve on the post-operative complications of older ones. The surgical options for the management of hemorrhoids today are many. Capturing all in a single article may be difficult if not impossible. The aim of this study therefore is to present in a concise form some of the common surgical options in current literature, highlighting some important post operative complications. Current literature is searched using MEDLINE, EMBASE and the Cochrane library. The conclusion is that even though there are many surgical options in the management of hemorrhoids today, most employ the ligature and excision technique with newer ones having reduced post operative pain and bleeding.

    Groin pain after transobturator synthetic mesh placement can be recalcitrant to conservative therapy and ultimately requires surgical excision. We describe our experiences with and technique of obturator foramen dissection for mesh excision. The records of 8 patients treated from 2005 to 2010, were reviewed. Obturator dissection was performed via a lateral groin incision over the inferior pubic ramus at the level of the obturator foramen, typically in conjunction with orthopedic surgery. Five patients had transobturator mid urethral sling surgery for stress urinary incontinence, 2 had mid urethral sling and trocar based anterior vaginal wall mesh kits with transobturator passage of mesh arms for stress urinary incontinence and pelvic organ prolapse, and 1 had an anterior vaginal wall mesh kit for pelvic organ prolapse. Patients had 0 to 2 prior transvaginal mesh excisions before obturator surgery. All patients presented with intractable pain in the area of the obturator foramen and/or medial groin for which conservative treatment measures had failed. Six patients underwent concurrent vaginal and obturator dissection and 2 underwent obturator dissection alone. In all cases residual mesh (3 to 11 cm) was identified and excised from the obturator foramen. Mesh was closely associated to or traversing the adductor longus muscle and tendon with significant fibrous reaction in all cases. Postoperatively 5 patients were cured of pain and/or infection, and 3 reported no or some improvement at a mean followup of 6 months (range 1 to 12). Our experience suggests that surgical excision of residual mesh can alleviate many of the symptoms in many patients. In all cases mesh remnants were identified and removed, and typically involved neuromuscular structures adjacent to the obturator foramen.

    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.

    Little is known about the spectrum of pediatric skin disorders requiring biopsy/excision, their indication, impact on further management, and the accuracy of clinical diagnosis. We aimed to address these questions in the patient population seen at our Swiss University referral center for Pediatric Dermatology and Plastic Surgery. All skin biopsies/excisions performed in patients aged ≤ 16 years over a period of 2 years were retrospectively analyzed. A total of 506 samples were included. The majority of biopsies/excisions (n = 413, 82%) was performed for tumors, cysts, and hamartomas and 18% for other skin conditions. Malignant tumors were found in 12 samples (2%) from four patients. In 121 (24%) patients, the histopathology had an important impact on patient management. In 80 (16%) cases, the pathology did not match with the clinical diagnosis. In 382 (75%) cases, excision was the treatment of choice. Of these, the indication for surgery was based on patient's request in 181 (47%) cases. Surgical interventions for pediatric skin disorders are performed for diagnostic and therapeutic reasons. In this cohort, histopathology was essential for treatment in one quarter of cases. Skin tumors, cysts, and hamartomas often require excision during childhood, with families' request and esthetic considerations playing an important role. What is Known: • The spectrum of pediatric skin conditions has been studied in outpatient, inpatient, and emergency settings. • In contrast, no data exist on the spectrum of pediatric skin disorders undergoing biopsy/excision specifically. What is New: • We analyze biopsies/excisions in children, focusing on diagnosis, indication, and impact on patient management. • Surgical interventions for skin disorders in children are often performed for tumors and hamartomas with esthetic considerations playing a relevant role. If used for diagnostic purposes, they are often performed to confirm or rule out severe skin disease.

    Osteochondritis dissecans (OCD) is a disorder of subchondral bone that causes adverse effects on the overlying cartilage and commonly affects the knee. The incidence of OCD and its long-term effect on the knee joint are controversial. Hypothesis/Purpose: The purpose of this study was to (1) evaluate the rate of osteoarthritis and knee arthroplasty in a population-based cohort of patients with OCD lesions treated operatively and (2) evaluate factors that may predispose patients to knee osteoarthritis and arthroplasty. The investigators hypothesized that OCD lesions diagnosed after skeletal maturity and treatment with fragment excision would be predictive of a diagnosis of osteoarthritis. Cohort study; Level of evidence, 3. The investigators identified 221 patients (mean ± SD age, 26.1 ± 13.6 years) with OCD lesions treated operatively between 1976 and 2010 and followed for 16.3 ± 11.4 years (mean ± SD) from diagnosis. Information related to the diagnosis, laterality of lesion, details of treatment, and progression to osteoarthritis was obtained from the medical record. Surgical treatment was classified as fragment excision, fragment preservation (lesion drilling and/or fragment fixation), or chondral defect grafting (osteochondral allograft or autograft). Factors predictive of osteoarthritis and arthroplasty were examined. There were 134 patients in the fragment excision group, 78 patients in the fragment preservation group, and 9 patients in the chondral defect grafting group. In the fragment excision group, the cumulative incidence of osteoarthritis was 12.0% at 5 years, 17.0% at 10 years, 26.0% at 15 years, 39.0% at 20 years, and 70% at 30 years. The cumulative incidence of arthroplasty was 2.0% at 5 years, 4.0% at 10 years, 4.0% at 15 years, 10.0% at 20 years, and 32.0% at 30 years. In the fragment preservation group, the cumulative incidence of osteoarthritis was 3.0% at 5 years, 7.0% at 10 years, 16.0% at 15 years, 25.0% at 20 years, and 51% at 30 years

    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

    First branchial cleft anomalies are uncommon, and only sporadic case reports are published in the literature. They account for 1% to 8% of all the branchial abnormalities. The often variable presentation and tract siting of first arch fistulae have led to misdiagnosis. The misdiagnosis results in inappropriate/ineffective treatment and recurrence of the sinus tract. We present a 19-year-old woman who presented to the ENT outpatient department with episodic discharge from a long-standing fistula anterior to the left sternomastoid muscle. This was associated with repeated episodes of ipsilateral tonsillitis. In relation to the history and because of the position of the fistula, a diagnosis of second branchial arch fistula was made. An attempt at excision was unfortunately followed by early recurrence of discharge. At review following the procedure, a defect of the left tympanic membrane in the form of a fibrous band was noted, and a revised diagnosis of first branchial arch sinus was made. Wide surgical excision of the tract with partial parotidectomy was performed. An uneventful postoperative course followed, with no recurrence of symptoms after 24 months of review. We discuss the case, the diagnostic pathway, and the wide local excision technique used for removal of branchial fistulae. Copyright © 2011 Elsevier Inc. All rights reserved.

    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)

    The purpose of this study was to determine the frequency of carcinoma at percutaneous directional vacuum-assisted removal (DVAR) in women with imaging-histologic discordance during ultrasound (US)-guided automated core needle biopsy, and to determine the role of DVAR in breast lesions with imaging-histologic discordance. A US-guided 14-gauge automated core needle biopsy was performed on 837 consecutive lesions. Imaging-histologic discordance was prospectively considered in 33 of 634 benign biopsies. DVAR was recommended in those lesions. Among the 33 lesions, 26 lesions that underwent subsequent DVAR or surgical excision made up our study population. Medical records, imaging studies, and histologic findings were reviewed. Among the 26 lesions, 18 lesions underwent subsequent US-guided DVAR, with 8-gauge probes for 15 of the lesions, and 11-gauge for three of the lesions. Two lesions were diagnosed as having carcinoma (2/18, 11.1% of upgrade rate; 3.1-32.8% CI). The remaining eight lesions underwent subsequent surgical excision, and carcinoma was diagnosed in one case (12.5% of upgrade rate; 2.2-47.1% CI). A US-guided DVAR of the breast mass with imaging-histologic discordance during US-guided 14-gauge automated core needle biopsy is a valuable alternative to surgery as a means of obtaining a definitive histological diagnosis.

    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

    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.

    PURPOSE: A number of authors have demonstrated the importance of using surgical clips to define the tumor bed in the treatment planning of early stage breast cancer. The clips have been useful in delineating the borders of the tangential fields especially for very medial and very lateral lesions as well as the boost volume. If surgical clips better define the tumor bed then a reduction in true or marginal recurrences should be appreciated. We sought to compare the incidence of breast recurrence in women with and without surgical clips controlling for other recognized prognostic factors. METHODS AND MATERIALS: Between 1980 and 1992, 1364 women with clinical Stage I or II invasive breast cancer underwent excisional biopsy, axillary dissection, and definitive irradiation. Median follow-up was 60 months. Median age was 55 years. Seventy-one percent of patients were path N0, 22% had 1-3 nodes and 7% had {>=} 4 nodes. Sixty-one percent were ER positive and 49% PR positive. Margin status was negative in 62%, positive in 10%, close in 9%, and unknown in 19%. Fifty-seven percent of women underwent a reexcision. Adjuvant chemotherapy {+-} tamoxifen was administered in 29%, and tamoxifen alone in 17%. Surgical clips were placed in the excision cavity in 556 patients while the other 808 did not have clips placed. All patients had a boost to the tumor bed. Patients had their boost planned with CT scanning or stereo shift radiographs. No significant differences between the 2 groups were noted for median age, T stage, nodal status, race, ER/PR receptor status, region irradiated, or tumor location. Patients without clips had negative margins less often, a higher rate of unknown or positive margins and more often received no adjuvant therapy compared to patients with surgical clips. RESULTS: Twenty-three and 27 patients with and without surgical clips, respectively developed a true or marginal recurrence in the treated breast. The actuarial probability of a breast recurrence was 2

    2014-01-01

    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.

    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

    A 22-years-old female patient at 171 cm and 67 kg visited the Department of Breast Surgery of the hospital with a mass accompanied with pain on the left side breast as chief complaints. Since physical examination revealed a suspected huge mass, breast surgeon decided to perform surgical excision and requested anesthesia to our department. Surgery of breast tumor is often under local anesthesia. However, in case of big size tumor, surgery is usually performed under general anesthesia. The patient feared general anesthesia. Unlike abdominal surgery, there is no need to control visceral pain for breast and anterior thoracic wall surgery. Therefore, we decided to perform resection under regional anesthesia. Herein, we report a successful anesthetic and pain management of the patient undergoing excision of a huge breast fibroadenoma under regional anesthesia using Pecs II and internal intercostal plane block.

    Surgical excision of meningioma is often complicated by significant blood loss requiring blood transfusion with its attendant risks. Although tranexamic acid is used to reduce perioperative blood loss, its blood conservation effect is uncertain in neurosurgery. Sixty adults undergoing elective craniotomy for meningioma excision were randomized to receive either tranexamic acid or placebo, initiated prior to skin incision. Patients in the tranexamic acid group received intravenous bolus of 20mg/kg over 20min followed by an infusion of 1mg/kg/h till the conclusion of surgery. Intraoperative blood loss, transfusion requirements and estimation of surgical hemostasis using a 5-grade scale were noted. Postoperatively, the extent of tumor excision on CT scan and complications were observed. Demographics, tumor characteristics, amount of fluid infusion, and duration of surgery and anesthesia were comparable between the two groups. The amount of blood loss was significantly less in tranexamic acid group compared to placebo (830mlvs 1124ml; p=0.03). The transfusion requirement was less in tranexamic acid group (p>0.05). The patients in tranexamic acid group fared better on a 5-grade surgical hemostasis scale with more patients showing good hemostasis (p=0.007). There were no significant differences between the groups with regards to extent of tumor removal, perioperative complications, hospital stay or neurologic outcome. To conclude, administration of tranexamic acid significantly reduced blood loss in patients undergoing excision of meningioma. Fewer patients in the tranexamic acid group received blood transfusions. Surgical field hemostasis was better achieved in patients who received tranexamic acid. Copyright © 2017 Elsevier Ltd. All rights reserved.

    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.

    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.

    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.

    Synovial chondromatosis (SC) is an uncommon disease characterized by a benign nodular cartilaginous proliferation arising from the joint synovium, bursae, or tendon sheaths. Although the temporomandibular joint is rarely affected by neoplastic lesions, SC is the most common neoplastic lesion of this joint. The treatment of this disease consists in the extraoral surgery with a wide removal of the lesion; in this study, the authors described a more conservative intraoral surgical approach. Patient with SC of temporomandibular joint typically refer a limitation in the mouth opening, together with a persistent not physiological mandibular protrusion and an appearance of a neoformation located at the right preauricular region: the authors reported 1 scholar patient. After biopsy of the neoformation, confirming the synovial chondromatosis, the patient underwent thus to the surgical excision of the tumor, via authors' conservative transoral approach, to facilitate the enucleation of the neoformation. The mass fully involved the pterygo-maxillary fossa with involvement of the parotid lodge and of the right TMJ: this multifocal extension suggested for a trans-oral surgical procedure, in the light of the suspicion of a possible malignant nature of the neoplasm. Our intraoral conservative approach to surgery is aimed to reduce the presence of unaesthetic scars in preauricular and facial regions, with surgical results undoubtedly comparable to the traditional surgical techniques much more aggressive. Our technique could be a valid, alternative, and safe approach to treat this rare and complex kind of oncological disease.

    Full Text Available Reconstruction of the eyelids after skin cancer excision can be challenging. Surgical treatment options are multiple; deep anatomy knowledge of lamellar components is mandatory to choose the most adequate surgical planning. Eyelids’ role in vision and social relationship is critical; both function and aesthetics are tough to restore. Using a flap provides a satisfying texture and colour match with adjacent tissues and ensures short contraction during healing; furthermore, grafts are sometimes necessary to achieve pleasing results. Hundreds of surgical techniques have been described aiming for eyelid reconstruction; in our paper, we want to provide for our audience the most reliable and useful procedures for subtotal and total eyelid reconstruction following NMSC full-thickness excision.

    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.

    Margin status is important in guiding decisions to re-excise following breast-conserving surgery (BCS) for breast cancer. The College of American Pathologists (CAP) developed guidelines to standardize pathology reporting; however, compliance with margin documentation guidelines has been shown to vary. The aim of this retrospective study was to determine whether compliance with CAP guidelines affects re-excision and mastectomy rates. We identified 1423 patients diagnosed with breast cancer between 1998 and 2006 who underwent BCS with negative margins. CAP compliance was categorized as maximal, minimal, or non-compliant. Statistical analyses were performed comparing the frequency of re-excision and mastectomy after initial BCS according to CAP margin reporting guideline compliance. Data were adjusted for provider facility by including a clustering variable within the regression model. Patients with non-compliant margin reporting were 1.7 times more likely to undergo re-excision and/or mastectomy than those with maximally compliant reporting. Level of compliance was most strongly associated with the frequency of mastectomy; non-compliant margin reporting was associated with a 2.5-fold increase in mastectomy rates compared to maximally compliant reporting. The results did not substantially change when the analyses accounted for clustering at the provider facility level. Our findings suggest that compliance with CAP guidelines in pathology reporting may be associated with variation in re-excision and mastectomy rates following BCS. Copyright © 2015 Elsevier Ltd.

    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 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.

    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.

    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.

    2010-01-01

    Background and purpose: To compare partial-breast clinical target volumes generated using a standard 15 mm margin (CTV standard ) with those generated using three-dimensional surgical excision margins (CTV tailored30 ) in women who have undergone wide local excision (WLE) for breast cancer. Material and methods: Thirty-five women underwent WLE with placement of clips in the anterior, deep and coronal excision cavity walls. Distances from tumour to each of six margins were measured microscopically. Tumour bed was defined on kV-CT images using clips. CTV standard was generated by adding a uniform three-dimensional 15 mm margin, and CTV tailored30 was generated by adding 30 mm minus the excision margin in three-dimensions. Concordance between CTV standard and CTV tailored30 was quantified using conformity (CoI), geographical-miss (GMI) and normal-tissue (NTI) indices. An external-beam partial-breast irradiation (PBI) plan was generated to cover 95% of CTV standard with the 95% isodose. Percentage-volume coverage of CTV tailored30 by the 95% isodose was measured. Results: Median (range) coronal, superficial and deep excision margins were 15.0 (0.5-76.0) mm, 4.0 (0.0-60.0) mm and 4.0 (0.5-35.0) mm, respectively. Median CoI, GMI and NTI were 0.62, 0.16 and 0.20, respectively. Median coverage of CTV tailored30 by the PBI-plan was 97.7% (range 84.9-100.0%). CTV tailored30 was inadequately covered by the 95% isodose in 4/29 cases. In three cases, the excision margin in the direction of inadequate coverage was ≤2 mm. Conclusions: CTVs based on 3D excision margin data are discordant with those defined using a standard uniform 15 mm TB-CTV margin. In women with narrow excision margins, the standard TB-CTV margin could result in a geographical miss. Therefore, wider TB-CTV margins should be considered where re-excision does not occur.

    Full Text Available Aims. Hidrocystomas are benign cystic growths of the apocrine and eccrine sweat glands. These cystic lesions have been well documented on the face, head, and neck, but rarely in the external auditory canal. Presentation of Case. A 67-year-old woman presented with a bluish cystic mass partially occluding the external auditory canal and interfering with hearing aid use. Lesion was excised completely via a transcanal endoscopic approach with excellent cosmetic results, no canal stenosis, and no recurrence at 1-year follow-up. Discussion. We present a rare eccrine hidrocystoma of the external auditory canal and successful excision of this benign lesion. We describe the surgical management using a transcanal endoscopic approach and follow-up results. An eccrine gland cyst that presents as a mass occluding the external auditory canal is quite rare. There are only a few such cases reported in the literature. These masses can be mistaken for basal cell carcinomas or cholesterol granulomas but can be easily differentiated using histopathology. Conclusion. Eccrine hidrocystoma is a cystic lesion of sweat glands, rarely found in the external auditory canal. A characteristic bluish hue aids in diagnosis and surgical excision using ear endoscopy provides excellent control.

  11. Recurrent pannus formation causing prosthetic aortic valve dysfunction: is excision without valve re-replacement applicable?

    Darwazah, Ahmad K

    2012-06-29

    Prosthetic valve dysfunction at aortic position is commonly caused by pannus formation. The exact etiology is not known. It arises from ventricular aspect of the prosthesis encroaching its leaflets causing stenosis or it may remain localized causing left ventricular outflow tract obstruction without affecting valve function.The difference in location entails different approaches in management. Such a pathology requires surgical excision of the pannus with or without valve re-replacement.A recurrent pannus was observed in a female patient who needed repeated surgical intervention to excise a localized pannus without re-replacement of a well functioning prosthetic valve.Management of our case presents several questions, whether recurrence of pannus is caused by sparing the prosthetic valve, is it simply an exaggeration of an inflammatory healing process in certain individuals or is it ideal to re-replace the valve despite a well preserved function.

    Accessory breasts have received little attention in the surgical fields, although the condition is quite common in the female population, with 2-6% of women suffering from it. Its convexity and cyclic pain make women feel embarrassed and uncomfortable, so patients often desire surgical excision to improve their appearances and to remove the pain. A total of 967 patients who had been treated by an excision of accessory breast tissue with liposuction using minimal incision from September 2013 to Dec 2015 at the Damsoyu Hospital were analyzed for clinical factors retrospectively. All 967 patients were female. There were 514 (53.2%) unmarried patients and 453 (46.8%) married patients. The major clinical manifestation was the problem in the appearance with cyclic pain in both unmarried and married groups (82.7 vs. 87.9%). Three types of accessory breasts were observed: 779 (80.6%) breast tissue only in axillae, 182 (18.8%) breast tissue with accessory nipple, and 6 (0.6%) breast tissue with accessory nipple-areolar complex. The mean operation time was 58 min. All cyclic axillar pain in our cases was resolved after the operation. Postoperative complications developed in 160 patients (16.55%). Among them, seroma after operation was the most common (11.27%). In our study, 95.65% of the patients were satisfied with the cosmetic outcomes. The surgical excision of accessory breasts with liposuction through the minimal incision is a safe and effective method to make women feel comfortable in clinical manifestations and be satisfied with their cosmetic axillar line.

    Papillary lesions of the breast range from benign to atypical to malignant. Although papillomas without frank cancer are benign, their management remains controversial. When a core needle biopsy of a lesion yields a diagnosis of intraductal papilloma with atypia, excision is generally recommended to rule out a concurrent malignant neoplasm. For intraductal papillomas without atypia, however, recommendations for excision versus observation are variable. The aims of this study are to evaluate the rate of concurrent malignancies for intraductal papilloma diagnosed on core needle biopsy and to assess the long-term risk of developing cancer after the diagnosis of a papillary lesion. This single institution retrospective study analyzed 259 patients that were diagnosed with intraductal papilloma (IDP) by core needle biopsy from 1995 to 2010. Patients were grouped by initial diagnosis into three groups (papilloma without atypia, papilloma with atypia, and papilloma with atypical duct hyperplasia or atypical lobular hyperplasia (ADH/ALH) and followed up for long-term outcomes. After a core needle biopsy showing IDP with atypia or IDP + ADH/ALH, surgical excision yielded a diagnosis of concomitant invasive or ductal in situ cancer in greater that 30% of cases. For intraductal papilloma without atypia, the likelihood of cancer was much lower. Moreover, even with excision, the finding of intraductal papilloma with atypia carries a significant risk of developing cancer long-term, and such patients should be followed carefully and perhaps should be considered for chemoprevention. © 2017 Wiley Periodicals, Inc.

    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.)

    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.

    To study the relationship between surgical management and prognosis of adrenocortical carcinoma (ACC) in order to guide the surgical management of ACC. Clinical data of 45 cases of ACC treated in our hospital were retrospectively analyzed. The 45 cases included 3 cases in stage I, 12 cases in stage II, 7 cases in stage III, and 23 cases in stage IV. 17 cases underwent complete excision, 14 cases underwent palliative excision, 8 cases had non-operative treatment and 6 cases gave up treatment. All patients were followed up from 2 to 141 months. The average survival time of 31 patients with surgery was 32.46 months, and the average survival time of 14 patients without surgery was 4.75 months. There were statistically significant differences between the two groups (p 0.05). Surgery is considered to be the only method to cure ACC. For ACC in stage I and II, tumor resection is the most effective treatment, and second surgical operation is recommended for local recurrence. For ACC in stage III, extensive surgical operation is recommended, and for ACC in stage IV, surgical operation has no effect on the prognosis. Copyright © 2012 S. Karger AG, Basel.

    To compare transanal endoscopic microsurgery (TEMS) with conventional transanal excision (TAE) in terms of the quality of resection, local recurrence, and survival rates in patients with stage I rectal cancer. Although TEMS is often considered a superior surgical technique to TAE, it is poorly suited for excising tumors in the lower third of the rectum. Such tumors may confer a worse prognosis. We retrospectively reviewed information on all patients with stage pT1 and pT2 rectal adenocarcinoma who underwent local excision from 1997 through mid-2006. We excluded patients with node-positive, metastatic, recurrent, previously irradiated, or snare-excised tumors. Our study included 42 TEMS and 129 TAE patients. We found no significant differences in patient characteristics, adjuvant therapy, tumor stage, or adverse histopathologic features. In the TAE group, 52 (40%) of tumors were TEMS group, only 1 (2%) (P = 0.0001). Surgical margins were less often positive in the TEMS group (2%) than in the TAE group (16%) (P = 0.017). For patients with tumors > or =5 cm from the AV, the estimated 5-year disease-free survival (DFS) rate was similar between the TEMS group (84.1%) and the TAE group (76.1%) (P = 0.651). But within the TAE group, the estimated 5-year DFS rate was better for patients with tumors > or =5 cm from the AV (76.1%) vs. TEMS or TAE) itself--were independent predictors of local recurrence and DFS. The quality of resection is better with TEMS than with TAE. However, the apparently better oncologic outcomes with TEMS can be partly explained by case selection of lower-risk tumors of the upper rectum.

    Full Text Available Renal clear cell carcinoma (RCCC is a neoplasia resistant to radio and chemotherapy, with surgical treatment being the procedure that is recognized for its curative treatment. This case report demonstrates the success of an aggressive surgical treatment for consecutive and late metachronous metastases following radical nephrectomy. CASE REPORT: Asymptomatic 50-year old man. During a routine examination, an incidental mass was found by renal ultrasonography. He underwent right radical nephrectomy due to RCCC in June 1992. During the follow-up metastases were evidenced in cerebellum on the seventh year, and in left lung and pancreas on the eighth year following the radical nephrectomy, with all of them successfully treated by surgical excision. COMMENTS: The surgical excision of consecutive and late metachronous metastases in different organs arising from RCCC is feasible, being a good therapeutic alternative in selected cases.

    To examine the most common presenting complaints of active-duty service members with isolated dorsal wrist ganglions and to determine the rate of return to unrestricted duty after open excision. Surgical records at 2 military facilities were screened to identify male and female active duty service members undergoing isolated open excision of dorsal wrist ganglions from January 1, 2006 to January 1, 2014. Electronic medical records and service disability databases were searched to identify the most common presenting symptoms and to determine whether patients returned to unrestricted active duty after surgery. Postoperative outcomes examined were pain persisting greater than 4 weeks after surgery, stiffness requiring formal occupational therapy treatment, surgical wound complications, and recurrence. A total of 125 active duty military personnel (Army, 54; Navy, 43; and Marine Corps, 28) met criteria for inclusion. Mean follow-up was 45 months. Fifteen percent (8 of 54) of the Army personnel were given permanent waivers from performing push-ups owing to persistent pain and stiffness. Pain persisting greater than 4 weeks after surgery was an independent predictor of eventual need for a permanent push-up waiver. The overall recurrence incidence was 9%. No demographic or perioperative factors were associated with recurrence. Patients whose occupation or activities require forceful wrist extension should be counseled on the considerable risk of residual pain and functional limitations that may occur after open dorsal wrist ganglion excision.

    Full Text Available Radial head excision has always been a safe commonly used surgical procedure with a satisfactory clinical outcome for isolated comminuted radial head fractures. However, diagnosis of elbow instability is still very challenging and often underestimated in routine orthopaedic evaluation. We present the case of a 21-years old female treated with excision after radial head fracture, resulting in elbow instability. The patient underwent revision surgery after four weeks. We believe that ligament reconstruction without radial head substitution is a safe alternative choice for Mason III radial head fractures accompanied by complex ligament lesions.

    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.

    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.

  6. Recurrent pannus formation causing prosthetic aortic valve dysfunction: Is excision without valve re-replacement applicable?

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Abstract Prosthetic valve dysfunction at aortic position is commonly caused by pannus formation. The exact etiology is not known. It arises from ventricular aspect of the prosthesis encroaching its leaflets causing stenosis or it may remain localized causing left ventricular outflow tract obstruction without affecting valve function. The difference in location entails different approaches in management. Such a pathology requires surgical excision of the pannus with or without valve re-replacement. A recurrent pannus was observed in a female patient who needed repeated surgical intervention to excise a localized pannus without re-replacement of a well functioning prosthetic valve. Management of our case presents several questions, whether recurrence of pannus is caused by sparing the prosthetic valve, is it simply an exaggeration of an inflammatory healing process in certain individuals or is it ideal to re-replace the valve despite a well preserved function.

    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.

    Surgeons share an interest with other physicians in establishing the diagnosis and prognosis of solid tumors in pediatric patients. This is in addition to the specific concern with the techniques of biopsy, staging, and excision of localized or metastatic disease. The surgeon is interested in all studies which predict the success or failure of attempts at total excision, which facilitate or increase the safety of complete or partial tumor removal, as well as those studies which clarify the overall prognosis. Within each of the following sections the surgeon's interests are discussed as follows: (1) relative to general studies and (2) relative to specific studies which influence techniques of biopsy and surgical staging or excision

    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

    2013-12-01

    Cases of femoral head and neck excision arthroplasty are infrequently reported in reptiles, and details of surgical technique and clinical outcome in chelonia are lacking. An adult female leopard tortoise (Stigmochelys pardalis) was presented with chronic non-weight-bearing lameness of the left hind limb. Examination and radiography were consistent with coxofemoral luxation, and as a result of the chronic presentation, surgical intervention was recommended. A cranial approach to the joint via the prefemoral fossa afforded good surgical exposure. A depressed lytic acetabular lesion was noted during the procedure, postulated to be a result of abnormal wear from the luxated femoral head. A fiberglass prop was used during recovery to allow extension of the limb without full weight-bearing. Lameness persisted postoperatively, but limb usage significantly improved.

    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.

    Full Text Available Purpose: Wide local excision (WLE is the preferred treatment of dermatofibrosarcoma protuberans (DFSP. The aim is to achieve negtive margins. We followed the impact of radiotherapy used postoperatively for both margin-negative and margin-positive DFSP tumors. Materials and Methods: Outcome of treatment of 36 patients of DFSP treated at our hospital was assessed. Thirty patients received radiotherapy postoperatively and six patients received radiotherapy alone. The maximum dimension of the lesion was 15 cm 2 . Patients were followed up for varying periods of time for any recurrence. Results: 10-year actuarial local control rate was determined. Local control was realized in six patients who were treated with radiotherapy alone. 30 patients were treated by radiotherapy and surgery. Out of these 30 patients, there were 6 local failures (failure rate 10%. Actuarial control rate was 82%. The failures were among patients who had positive margins. Conclusion: Radiotherapy is effective, and it decreases the recurrence rate in the treatment of DFSP. It is especially helpful in margin-positive disease. This appears true for patients treated with radiotherapy alone or radiotherapy used postoperatively.

    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

    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{sup 1} sphere' which may introduce numerical instabilities into the evolution. In this paper I describe an alternate scheme which uses multiple {l_brace}r x (angular coordinates){r_brace} 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 {gamma}-tilde{sup i} (I use a scheme which requires ghost zones which are twice as wide for the BSSN conformal factor {phi} as for {gamma}-tilde{sup 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{sup 2} = 0.6, I present evolutions to t {approx}> 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.

    Excision of arteriovenous malformations (AVMs) is known to carry a risk of postoperative hemorrhage, postulated to be the result of normal perfusion pressure breakthrough. It is also possible that AVMs may cause a steal effect, reducing perfusion in nearby vessels. There is currently no simple method of visualizing the presence or absence of steal effect intraoperatively. We hypothesized that the infrared thermographic (heat sensitive) imaging of perilesional brain may be useful for detecting reduced perfusion due to steal. Moreover, we hypothesized that if steal effect was present, it could impact on ocular perfusion and thereby temperature. Our objective was, therefore, to investigate whether perilesional cortical and ocular temperature (OT) may be a marker of steal effect. We intraoperatively acquired conventional and thermal images of the surgical field and eyes bilaterally, pre- and post-excisions of a large left hemisphere AVM. We found OT asymmetry preoperatively, which was absent after the AVM was excised. Intraoperative thermal images showed an increase of perilesional temperature, although this could be confounded by generalized changes in cortical perfusion due to anesthetics or surgery.

    Epulis is a benign hyperplasia of the oral soft tissues. Surgical excision always extends to the periosteum and includes scaling of adjacent teeth to remove any possible irritants. The esthetics of the soft tissues may be compromised, however. This article studies three cases in which an immediate laterally positioned flap (LRF) was used to repair mucogingival defects after epulis biopsies. After 24 months, the color and shape of the surgical areas were healthy and stable, nearly complete root coverage was evident, and no lesions reoccurred. For repairing gingival defects after biopsy, LRF appears to be minimally traumatic while promoting esthetic outcomes.

    Introduction: Epulis granulomatosa is a lesion which grows from an extraction socket. It can be misdiagnosed with lesions of the same clinical appearance such as: foreign body or pyogenic granuloma, or as a herniation of the maxillary sinus. The most common treatment is surgical excision. Case report: The present article reports an Epulis granulomatosa which was removed with diode laser (810 nm) due to child’s fear related to traditional surgical instruments and bleeding. Results and conclusion: Lasers are useful for soft tissue surgery in modern dentistry, especially in relation to pediatric patients due to the rapid and regular wound healing without sutures.

    There are limited data in the literature that describe the management of Peyronie's disease (PD) with severe compound curvature, which often requires additional straightening procedures after plaque excision and grafting (PEG) to achieve functional penile straightening (compound curvature treated with PEG and supplemental tunica albuginea plication (TAP). We performed a retrospective chart review of patients with PD and acute angulation who underwent PEG (group 1) and patients with compound curvature who underwent PEG with TAP (group 2) between 2007 and 2016. Primary post-operative outcomes of interest include change in penile curvature, change in measured stretched penile length, and subjective report on penile sensation and sexually induced penile rigidity. 240 Men with PD were included in the study, of which 79 (33%) patients in group 1 underwent PEG and 161 (67%) in group 2 underwent PEG and TAP. There was no difference in associated PD co-morbidities including age, hypertension, hyperlipidemia, hypogonadism, diabetes, or tobacco use. After artificial induction of erection with intracorporal trimix injection, the average primary curvature was 73 (range, 20-120) degrees for group 1 compared to 79 (range, 35-140) degrees for group 2 (P = .01). Group 2 had an average secondary curvature of 36 (20-80 degrees). After completion of PEG, men in group 2 had an average residual curvature of 30 (range, 20-50) degrees which required 1-6 TAPs to achieve functional straightness (compound curvature to date. Limitations of this study include the retrospective nature of the analysis as well as the lack of a validated objective measurement of erectile function after penile straightening. Our study found no baseline difference in underlying co-morbidities in men with severe compound curvature compared with men with acute severe angulated curvature. Men with severe compound curvature represent a severe and under-recognized population of men with PD who can be surgically

    Intramedullary ependymomas are uncommon tumors that can occur within the medullary substance of the spinal cord. Despite this difficult location, they are typically benign tumors that can most often be removed completely with an acceptable surgical risk. Therefore, the recommended management approach is usually surgical excision. This review will consider the historical context in which surgeons began treating these tumors and then review the more recent literature that guides their current management.

    A vaginal introital defect case and its symptomatology have never been published before. The objective of this presentation was to describe symptoms associated with an acquired sensation of wide vagina and to present a new surgical treatment for anterior vaginal introital defects. A 42-year-old, Caucasian woman, G4P4013, presented with a sensation of wide vagina at the vaginal opening and a history of colpoperineoplasty, without mesh, for the same condition 4 years prior. Clinical evaluation documented anterior vaginal introital defects and the absence of vaginal site-specific defects. Reconstruction of a vaginal introital defect was completed without complications. Surgical resolution of symptoms and signs of this condition were noted. Anterior vaginal introitoplasty can assist in the management of an acquired sensation of wide vagina.

    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)

    Objective. To describe the effects of surgical treatment and complications in 46 patients with carotid body tumor (CBT). Method. Retrospective study on surgical treatment and complications was carried out in 46 cases of CBT which were surgically treated with different kind of procedures. Result. All procedures performed successfully except that the CBT was not excised in 4 cases. No operative mortality was observed. There were 2 postoperative hemiplegia, 4 hypoglossal nerve impairment,2 glossopharyngeal nerve impairment, 1 vagus nerve impairment, and 1 accessory nerve impairment. One patient presented postoperative cranial nerve impairment in glossopharyngeal, vagus and hypoglossal nerves. Two patients developed local recurrence during the long-term follow-up. Conclusion. Complete surgical excision was possible in each patient if the diagnosis had been correctly made through selective preoperative angiography, vessel ultrasound Doppler and other examinations.Reasonable surgical procedure and Matas training were necessary to the successful surgical treatment and thus decrease the complicative incidence rate of carotid chemodectomas.

    Arthroscopy is an advancing field in orthopedics, the applications of which have been expanding over time. Traditionally, excision of ganglion cysts has been done in an open fashion. However, more recently, studies show outcomes following arthroscopic excision to be as good as open excision. Cosmetically, the incisions are smaller and heal faster following arthroscopy. In addition, there is the suggested benefit that patients will regain function and return to work faster following arthroscopic excision. More prospective studies comparing open and arthroscopic excision of ganglion cysts need to be done in order to delineate if there is a true functional benefit. Copyright © 2014 Elsevier Inc.

    Traditionally, surgical education has been confined to operating and lecture theaters. Access to the World Wide Web and services, such as YouTube and iTunes has expanded enormously. Each week throughout Ireland, nonconsultant hospital doctors work hard to create presentations for surgical teaching. Once presented, these valuable presentations are often never used again. We aimed to compile surgical presentations online and establish a new online surgical education tool. We also sought to measure the effect of this educational tool on surgical presentation quality. Surgical presentations from Cork University Hospital and Beaumont Hospital presented between January 2010 and April 2011 were uploaded to http://www.pilgrimshospital.com/presentations. A YouTube channel and iTunes application were created. Web site hits were monitored. Quality of presentations was assessed by 4 independent senior surgical judges using a validated PowerPoint assessment form. Judges were randomly given 6 presentations; 3 presentations were pre-web site setup and 3 were post-web site setup. Once uploading commenced, presenters were informed. A total of 89 presentations have been uploaded to date. This includes 55 cases, 17 journal club, and 17 short bullet presentations. This has been associated with 46,037 web site page views. Establishment of the web site was associated with a significant improvement in the quality of presentations. Mean scores for pre- and post-web site group were 6.2 vs 7.7 out of 9 respectively, p = 0.037. This novel educational tool provides a unique method to enable surgical education become more accessible to trainees, while also improving the overall quality of surgical teaching PowerPoint presentations.

    To analyze our experience in translating the concept of total mesorectal excision to "no-touch" complete removal of an intact mesocolonic envelope (complete mesocolic excision), along with central vascular ligation and apical node dissection, in the surgical treatment of right-sided colonic cancers, comparing "mesocolic" to less radical "non-mesocolic" planes of surgery in respect to quality of the surgical specimen and long-term oncologic outcome. A total of 115 patients with right-sided colonic cancers were retrospectively enrolled from 2008 to 2013 and operated on following the intent of minimally invasive complete mesocolic excision with central vascular ligation. Morbidity and mortality were 22.6% and 1.7%, respectively. Mesocolic, intramesocolic, and muscularis propria planes of resection were achieved in 65.2%, 21.7%, and 13% of cases, respectively, with significant impact for mesenteric plane of surgery on R0 resection rate (97.3%), circumferential resection margin plane of surgery, with R0 resection rate and overall survival falling to 72% and 60%, respectively, and with circumferential resection margin planes of "standard" surgery, significantly impacting loco-regional control and thus overall survival. © The Finnish Surgical Society 2014.

    Full Text Available 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

    2016-01-01

    Full Text Available Endometriosis is defined as the presence of endometrial mucosa (glands and stroma abnormally implanted in locations other than the uterine cavity. Deep infiltrating endometriosis (DIE is considered the most aggressive presentation of the disease, penetrating more than 5 mm in affected tissues, and it is reported in approximately 20% of all women with endometriosis. DIE can cause a complete distortion of the pelvic anatomy and it mainly involves uterosacral ligaments, bladder, rectovaginal septum, rectum, and rectosigmoid colon. This review describes the state of the art in laparoscopic approach for DIE with a special interest in intestinal involvement, according to recent literature findings. Our attention has been focused particularly on full-thickness excision versus shaving technique in deep endometriosis intestinal involvement. Particularly, the aim of this paper is clarifying from the clinical and methodological points of view the best surgical treatment of deep intestinal endometriosis, since there is no standard of care in the literature and in different surgical settings. Indeed, this review tries to suggest when it is advisable to manage the full-thickness excision or the shaving technique, also analyzing perioperative management, main complications, and surgical outcomes.

    Full Text Available We report a four-year-old boy with a nevus covering all the plantar side of his second finger on the left foot. He was also affected by congenital phimosis. Surgical excision of the nevus was indicated, but the skin defect would have been too large to be directly closed. The foreskin was taken as a full-thickness skin graft to cover the cutaneous defect of the finger. The graft intake was favourable and provided a functional repair with good aesthetic characteristic.

  14. Global-genome Nucleotide Excision Repair Controlled by Ubiquitin/Sumo Modifiers

    Directory of Open Access Journals (Sweden)

    Peter eRuethemann

    2016-04-01

    Full Text Available Global-genome nucleotide excision repair (GG-NER prevents genome instability by excising a wide range of structurally unrelated DNA base adducts and crosslinks induced by chemical carcinogens, ultraviolet (UV radiation or intracellular metabolic by-products. As a versatile damage sensor, xeroderma pigmentosum group C (XPC protein initiates this generic defense reaction by locating the damage and recruiting the subunits of a large lesion demarcation complex that, in turn, triggers the excision of aberrant DNA by endonucleases. In the very special case of a DNA repair response to UV radiation, the function of this XPC initiator is tightly controlled by the dual action of cullin-type CRL4DDB2 and sumo-targeted RNF111 ubiquitin ligases. This twofold protein ubiquitination system promotes GG-NER reactions by spatially and temporally regulating the interaction of XPC protein with damaged DNA across the nucleosome landscape of chromatin. In the absence of either CRL4DDB2 or RNF111, the DNA excision repair of UV lesions is inefficient, indicating that these two ubiquitin ligases play a critical role in mitigating the adverse biological effects of UV light in the exposed skin.

    2014-01-01

    Various conservative approaches have been utilized to manage large periapical lesions. This article presents a relatively new, very conservative technique known as surgical fenestration which is both diagnostic and curative. The technique involves partially excising the cystic lining, gently curetting the cystic cavity, performing copious irrigation, and closing the surgical site. This technique allows for decompression and allows the clinician the freedom to take a biopsy of the lesion, as well as perform other procedures such as root resection and retrograde sealing, if required. As the procedure does not perform a complete excision of the cystic lining, it is both minimally invasive and cost-effective. The technique and the concepts involved are reviewed in 4 cases treated with this novel surgical approach.

    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.

    Scrotal lymphedema (scrotal elephantiasis) is uncommon outside of filariasis endemic regions. We present a case of a 65-year-old with idiopathic lymphedema of the scrotum and functional impairment of the penis. The patient underwent surgical excision of the edematous subcutaneous tissues and plastic reconstruction of his penis and scrotum. Three years later, the patient showed no signs of local recurrence, had complete restoration of urinary and sexual function and was extremely satisfied with the result. Surgical management was an effective strategy in the management of scrotal lymphedema in this case.

    We present a pure transvaginal approach to the removal of eroded mesh involving the bladder secondary to placement of transvaginal mesh for management of pelvic organ prolapse (POP) using a mesh kit. Although technically challenging, we demonstrate the feasibility of a purely transvaginal approach, avoiding a potentially more morbid transabdominal approach. The video presents the surgical technique of pure transvaginal excision of mesh erosion involving the bladder after mesh placement using a prolapse kit was performed. This video shows that purely transvaginal removal of mesh erosion involving the bladder can be done safely and is feasible.

    Despite the fact that the hallucal sesamoids play a crucial role in forefoot mechanics, disorders resulting from pathology of these structures are often overlooked or misdiagnosed. Avascular necrosis (AVN) of the hallucal sesamoids is a rare condition that must be differentiated from other pathologies, such as fractures, pseudarthrosis or osteomyelitis. We report on two patients with AVN of the fibular (lateral) hallucal sesamoid (Morbus Renander). In both patients the necrotic part of the fibular sesamoid was excised surgically after failed conservative therapy. The followup was 29 and 26 months. The clinical and radiological results showed a complete relief of pain in both patients without any complications or forefoot deformities. Recent literature and own experiences support non-operative initial management including anti-inflammatory medications, shoe modification and temporary limited weight bearing. If symptoms persist, surgical treatment with excision of the necrotic part of the sesamoid may be an alternative. Consideration by the surgeon should be given to protecting the neurovascular bundle and reattaching intrinsic tendons and ligaments if necessary. Satisfying results can be achieved by surgical removal.

  20. The effect of coracoacromial ligament excision and acromioplasty on the amount of rotator cuff force production necessary to restore intact glenohumeral biomechanics.

    Coracoacromial ligament (CAL) excision and acromioplasty increase superior and anterosuperior glenohumeral translation. It is unknown how much of an increase in rotator cuff force production is required to re-establish intact glenohumeral biomechanics after these surgical procedures. We hypothesized that, after CAL excision and acromioplasty, an increase in rotator cuff force production would not be necessary to reproduce the anterosuperior and superior translations of the intact specimens. Nine cadaveric shoulders were subjected to loading in the superior and anterosuperior directions in the intact state after CAL excision, acromioplasty, and recording of the translations. The rotator cuff force was then increased to normalize glenohumeral biomechanics. After CAL excision at 150 and 200 N of loading, an increase in the rotator cuff force by 25% decreased anterosuperior translation to the point where there was no significant difference from the intact specimen's translation. After acromioplasty (and CAL excision) at 150 and 200 N, an increase in the rotator cuff force of 25% and 30%, respectively, decreased superior translation to the point where there was no significant difference from the intact specimen's translation. At 150 to 200 N of loading, CAL excision and acromioplasty increase the rotator cuff force required to maintain normal glenohumeral biomechanics by 25% to 30%. After a subacromial decompression, the rotator cuff has an increased force production requirement to maintain baseline glenohumeral mechanics. Under many circumstances, in vivo force requirements may be even greater after surgical attenuation of the coracoacromial arch. Basic Science Study; Biomechanics.

    Radial head excision has always been a safe commonly used surgical procedure with a satisfactory clinical outcome for isolated comminuted radial head fractures. However, diagnosis of elbow instability is still very challenging and often underestimated in routine orthopaedic evaluation. We present the case of a 21-years old female treated with excision after radial head fracture, resulting in elbow instability. The patient underwent revision surgery after four weeks. We believe that ligament reconstruction without radial head substitution is a safe alternative choice for Mason III radial head fractures accompanied by complex ligament lesions.

    Full Text Available Sarcomas arising from the chest wall account for less than 20% of all soft tissue sarcomas, and at this site, primitive tumors are the most frequent to occur. Leiomyosarcoma is a malignant smooth muscle tumor and the best outcomes are achieved with wide surgical excision. Although advancements have been made in treatment protocols, leiomyosarcoma remains one of the more difficult soft tissue sarcoma to treat. Currently, general local control is obtained with surgical treatment with wide negative margins. We describe the case of a 50-year-old man who underwent a chest wall resection involving a wide portion of the pectoralis major and minor muscle, the serratus and part of the second, third and fourth ribs of the left side. The full-thickness chest wall defect of 10 × 8 cm was closed using a non-cross-linked acellular dermal matrix (Egis® placed in two layers, beneath the rib plane and over it. A successful repair was achieved with no incisional herniation and with complete tissue regeneration, allowing natural respiratory movements. No complications were observed in the postoperative course. Biological non-cross-linked matrix, derived from porcine dermis, behaves like a scaffold supporting tissue regeneration; it can be successfully used as an alternative to synthetic mesh for chest wall reconstruction.

    Purpose To evaluate outcomes of Savi Scout (Cianna Medical, Aliso Viejo, Calif) reflector-guided localization and excision of breast lesions by analyzing reflector placement, localization, and removal, along with target excision and rates of repeat excision (referred to as re-excision). Materials and Methods A single-institution retrospective review of 100 women who underwent breast lesion localization and excision by using the Savi Scout surgical guidance system from June 2015 to May 2016 was performed. By using image guidance 0-8 days before surgery, 123 nonradioactive, infrared-activated, electromagnetic wave reflectors were percutaneously inserted adjacent to or within 111 breast targets. Twenty patients had two or three reflectors placed for bracketing or for localizing multiple lesions, and when ipsilateral, they were placed as close as 2.6 cm apart. Target and reflector were localized intraoperatively by one of two breast surgeons who used a handpiece that emitted infrared light and electromagnetic waves. Radiographs of the specimen and pathologic analysis helped verify target and reflector removal. Target to reflector distance was measured on the mammogram and radiograph of the specimen, and reflector depth was measured on the mammogram. Pathologic analysis was reviewed. Re-excision rates and complications were recorded. By using statistics software, descriptive statistics were generated with 95% confidence intervals (CIs) calculated. Results By using sonographic (40 of 123; 32.5%; 95% CI: 24.9%, 41.2%) or mammographic (83 of 123; 67.5%; 95% CI: 58.8% 75.1%) guidance, 123 (100%; 95% CI: 96.4%, 100%) reflectors were placed. Mean mammographic target to reflector distance was 0.3 cm. All 123 (100%; 95% CI: 96.4%, 100%) targets and reflectors were excised. Pathologic analysis yielded 54 of 110 malignancies (49.1%; 95% CI: 39.9%, 58.3%; average, 1.0 cm; range, 0.1-5 cm), 32 high-risk lesions (29.1%; 95% CI: 21.4%, 38.2%), and 24 benign lesions (21.8%; 95% CI

    In the clinic of dermatological surgery, I Department of Dermatology Silesian Medical Academy in Katowice 328 patients were treated surgically for granuloma teleangiectodes in the years 1973-1988. Two methods were used: excision of the lesion and curettage with electrocoagulation of the base of the lesion. After excision the wound was closed by approximation of its margins or local plastic procedure (285 cases) and by covering it with a free full-thickness skin graft (3 cases). Curettage and electrocoagulation was used in 43 cases, mainly due to the location of the lesion (in 90% on fingers). After granuloma excision no recurrences were observed, while after curettage and electrocoagulation recurrences developed in 20% of cases.

    In-office laryngeal surgery is taking on a more commonplace role in the treatment of laryngeal disorders. The potassium-titanyl-phosphate (KTP) laser has been a resourceful adjunct to the management of patients with mucosal lesions of the vocal cords. However, a paucity of data exists for its use in postintubation granulomas treated in-office. A 43-year-old female presented with voice hoarseness and found to have a large obstructing postintubation granuloma which was treated by in-office KTP laser and en masse excision. We report the successful case of a patient receiving in-office treatment for a large vocal process granuloma using the KTP laser with en masse excision. The combined use of the KTP laser and forceps in-office can be valuable to the surgical management of vocal process granulomas, given their numerous recurrences. New avenues in office-based surgical management of laryngeal disorders can offer accessibility and decreased morbidity to patients. Copyright © 2016 The Voice Foundation. Published by Elsevier Inc.

    2012-07-01

    Sacral colpopexy may be complicated by mesh exposure, and the surgical treatment of mesh exposure typically results in minor postoperative morbidity and few delayed complications. A 75-year-old woman presented 7 years after a laparoscopic sacral colpopexy, with Mersilene mesh, with an apical mesh exposure. She underwent an uncomplicated transvaginal excision and was asymptomatic until 8 months later when she presented with vaginal drainage and a sacral abscess. This was successfully treated with laparoscopic enterolysis, drainage of the abscess, and explantation of the remaining mesh. Incomplete excision of exposed colpopexy mesh can lead to ascending infection and sacral abscess. Laparoscopic drainage and mesh removal may be considered in these patients.

    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.

    Peyronie's disease (PD) is a debilitating disorder in which collagen deposition, fibrosis, and plaques in the tunica albuginea result in penile curvature, shortening, and pain. For severe curvatures requiring plaque incision or excision with grafting (PIEG), a subcoronal circumcising incision with penile degloving has historically been used. The aim of this study was to report our unique approach to PIEG via a longitudinal "window" incision for the correction of PD, minimizing the surgical manipulation and dissection accompanying the traditional circumcising incisional approach that may lead to increased postoperative edema, pain, and prolonged healing time. A patient presented with a stable, painless, 90-degree midshaft leftward curvature causing penetration difficulties and painful intercourse for his partner. His Sexual Health Inventory for Men (SHIM) score was 23. The patient opted for surgical correction with plaque excision and grafting via a 4-cm longitudinal incision overlying the point of maximal curvature along the left lateral penile shaft. This direct access to the left corpus cavernosum and plaque, along with dissecting skin, dartos, and Buck's fascia, created a window with sufficient exposure for excision and patch grafting. The main outcome measures were objective data and subjective data in men undergoing PIEG via lateral longitudinal "window" incision for PD repair. The plaque was excised and a porcine small intestinal submucosa graft was sewn in. Intraoperative artificial tumescence at the end of surgery revealed complete correction of the curvature. The patient experienced painless rigid erections by postoperative day three with minimal penile edema. By postoperative week four, he could successfully partake in coitus. His SHIM score remained unchanged. At maximum follow-up 6 months postoperatively, he still endorsed excellent cosmetic and functional outcomes with spontaneous unassisted erections and no recurrence of his curvature. A lateral

    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.

    Branchial abnormalities occur when there is disturbance in the maturation of the branchial apparatus during fetal development. Branchial anomalies are congenital lesions usually present in childhood, even if they can be diagnosed later for enlargement or infection. A correct diagnosis will lead to proper management: complete surgical excision is the treatment of choice. The purpose of this article is to present clinical features, diagnostic methods and surgical treatment of branchial anomalies in childhood, based on a series of 50 patients. We conducted a retrospective analysis of a total of 50 pediatric patients operated from June 2005 to June 2014 for the presence of branchial cleft anomalies. 27 cases (54 %) presented a second branchial cleft fistula and 11 cases (22 %) a second branchial cleft cyst and one case (2 %) presented both cyst and sinus of the second branchial cleft; four cases (8 %) presented first branchial cleft cyst whereas four cases (8 %) a first branchial cleft sinus and two cases (4 %) a first branchial cleft fistula; one case (2 %) presented a piriform sinus fistula (third branchial cleft). None of our patients presented anomalies of the fourth branchial cleft. All patients underwent surgical treatment and lesions have been removed by excision or fistulectomy. No post-surgical complication occurred. The rate of recurrence was 4 %. Pre-operative diagnosis supplies important information to the surgeon for a proper therapy: a complete excision of the lesion without inflammatory signs is essential to avoid re-intervention and to achieve a good outcome.

    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.

    The authors report their personal experience of the "excision and primary suture" operating technique in the surgical treatment of pilonidal sinus. A rapid recovery by postoperative day 10 was achieved in 58 out of 60 cases treated (96.7%). Dehiscence of the surgical wound was observed in 2 cases (3.3%) following ischemic lesion caused by decubitus of the cutaneous margins and healing occurred by second intenti. No cases of short- or long-term recidivation were observed. The advantages of this method are the early return to working activities, minor patient discomfort and the reduced risk that the surgical would might become infected. Three basic stages for the successful outcome of this type of surgery have been identified as follows: 1) Although and accurate tricotomy of the sacro-coccigeal region. Antibiotic therapy is started about 2 hours before surgery. 2) The precise execution of the surgical technique. 3) The continuation of antibiotic therapy until postoperative day 7. Compressive medication is removed on postoperative day 4. If these three basic stages are respected, no cases of recidivation will occur.

    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.

    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

    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

    Full Text Available Nevus comedonicus is a rare epidermal abnormality of the pilosebaceous unit, which is congenital in most patients but may also appear early in childhood. It may be localized or have an extensive involvement, the latter showing a unilateral predominance with only a few cases presenting bilaterally. Extensive nevus comedonicus can be associated with musculoskeletal defects, eye and neurological involvement, which constitutes nevus comedonicus syndrome. Uncomplicated nevus comedonicus can be treated with topical keratolytics, diode, erbium laser, and ultrapulse CO2 laser. Surgical excision can be performed to ensure complete removal and nonrecurrence. This case report refers to a young male patient with extensive nevus comedonicus present over left chest, left axilla, and left upper back without systemic involvement, treated with staged surgical excision and resurfacing.

    Abstract Prosthetic valve dysfunction at aortic position is commonly caused by pannus formation. The exact etiology is not known. It arises from ventricular aspect of the prosthesis encroaching its leaflets causing stenosis or it may remain localized causing left ventricular outflow tract obstruction without affecting valve function. The difference in location entails different approaches in management. Such a pathology requires surgical excision of the pannus with or without valve re-replace...

    2017-11-01

    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.

    Advances in computer imaging and technology have facilitated enhancement in surgical planning with a 3-dimensional model of the surgical plan of action utilizing advanced visualization tools in order to plan individual interactive operations with the aid of the dextroscope. This provides a proper 3-dimensional imaging insight to the pathological anatomy and sets a new dimension in collaboration for training and education. The case of a seventeen-year-old female, being operated with the aid of a preoperative 3-dimensional virtual reality planning and the practical application of the neurosurgical operation, is presented. This young lady presented with a two-year history of recurrent episodes of severe, global, throbbing headache with episodes of projectile vomiting associated with shoulder pain which progressively worsened. She had no obvious neurological deficits on clinical examination. CT and MRI showed a contrast-enhancing midline posterior fossa space-occupying lesion. Utilizing virtual imaging technology with the aid of a dextroscope which generates stereoscopic images, a 3-dimensional image was produced with the CT and MRI images. A preoperative planning for excision of the lesion was made and a real-time 3-dimensional volume was produced and surgical planning with the dextroscope was made and the lesion excised. Virtual reality has brought new proportions in 3-dimensional planning and management of various complex neuroanatomical problems that are faced during various operations. Integration of 3-dimensional imaging with stereoscopic vision makes understanding the complex anatomy easier and helps improve decision making in patient management.

    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 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.

    To review fibrosis of fluocinolone acetonide (FA) implants in subjects with CAPN5 autosomal dominant neovascular inflammatory vitreoretinopathy (ADNIV). A retrospective case series was assembled from ADNIV patients in which there was fibrotic encapsulation of a fluocinolone acetonide implant. CAPN5 genotypes and surgical repair techniques were reviewed. Two eyes of two ADNIV patients developed a fibrotic capsule over the fluocinolone acetonide implant. Both patients had Stage IV disease. Patient A had a c.731T > C mutation in the CAPN5 gene and patient B had a c.728G > T mutation. The fibrotic membrane was surgically excised and the implant function was restored. The exuberant fibrotic response in later stages of ADNIV may be resistant to local immunosuppression with steroids. Surgical excision of fibrotic membranes over FA implants can reestablish local steroid delivery in cases of severe proliferative vitreoretinopathy.

    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.

    Introduction Peyronie’s disease (PD) is a debilitating disorder in which collagen deposition, fibrosis, and plaques in the tunica albuginea result in penile curvature, shortening, and pain. For severe curvatures requiring plaque incision or excision with grafting (PIEG), a subcoronal circumcising incision with penile degloving has historically been used. Aims The aim of this study was to report our unique approach to PIEG via a longitudinal “window” incision for the correction of PD, minimizing the surgical manipulation and dissection accompanying the traditional circumcising incisional approach that may lead to increased postoperative edema, pain, and prolonged healing time. Methods A patient presented with a stable, painless, 90-degree midshaft leftward curvature causing penetration difficulties and painful intercourse for his partner. His Sexual Health Inventory for Men (SHIM) score was 23. The patient opted for surgical correction with plaque excision and grafting via a 4-cm longitudinal incision overlying the point of maximal curvature along the left lateral penile shaft. This direct access to the left corpus cavernosum and plaque, along with dissecting skin, dartos, and Buck’s fascia, created a window with sufficient exposure for excision and patch grafting. Main Outcome Measures The main outcome measures were objective data and subjective data in men undergoing PIEG via lateral longitudinal “window” incision for PD repair. Results The plaque was excised and a porcine small intestinal submucosa graft was sewn in. Intraoperative artificial tumescence at the end of surgery revealed complete correction of the curvature. The patient experienced painless rigid erections by postoperative day three with minimal penile edema. By postoperative week four, he could successfully partake in coitus. His SHIM score remained unchanged. At maximum follow-up 6 months postoperatively, he still endorsed excellent cosmetic and functional outcomes with spontaneous

    Nowadays surgical intervention is an essential part of the treatment of idiopathic gynecomastia. Choosing the right method is crucial and is based on the current status in the clinical and histological evaluation. Before finalizing the process of choosing a specific method a prior interdisciplinary evaluation of the patient is necessary to ascertain clear indications for a surgical intervention. Liposuction is one of the methods which have become popular in recent years. The advantages are the possible combination with traditional techniques, such as subcutaneous mastectomy or periareolar mastopexy. The main indication is for gynecomastia stage IIa/b and is justifiable due to the reduction in surgical complications and scarring. Furthermore this technique provides an excellent aesthetical outcome for the patient. A total of 162 patients suffering from gynecomastia stages I-III (according to Simon) were surgically treated between 2000 and 2010 and these cases were retrospectively evaluated. The results showed a decline in the use of a T-shaped incision in combination with subcutaneous mastectomy with periareolar tightening compared to an increase in the use of subcutaneous mastectomy in combination with liposuction. The excised tissue should always be sent for histological examination to make sure no malignant cells were present.

    The Society of Surgical Oncology and American Society of Radiation Oncology consensus statement was the first professional guideline in breast oncology to declare "no ink on tumor" as a negative margin in patients with stages I/II breast cancer undergoing breast-conservation therapy. We sought to analyze the financial impact of this guideline at our institution using a historic cohort. We identified women undergoing re-excision after breast-conserving surgery for invasive breast cancer from 2010 through 2013 using a prospectively maintained institutional database. Clinical and billing data were extracted from the medical record and from administrative resources using CPT codes. Descriptive statistics were used in data analysis. Of 254 women in the study population, 238 (93.7%) had stage I/II disease and 182 (71.7%) had invasive disease with ductal carcinoma in situ. A subcohort of 83 patients (32.7%) who underwent breast-conservation therapy for stage I/II disease without neoadjuvant chemotherapy had negative margins after the index procedure, per the Society of Surgical Oncology and American Society of Radiation Oncology guideline. The majority had invasive ductal carcinoma (n = 70 [84.3%]) and had invasive disease (n = 45 [54.2%]), and/or ductal carcinoma in situ (n = 49 [59.0%]) within 1 mm of the specimen margin. Seventy-nine patients underwent 1 re-excision and 4 patients underwent 2 re-excisions, accounting for 81 hours of operative time. Considering facility fees and primary surgeon billing alone, the overall estimated cost reduction would have been $195,919, or $2,360 per affected patient, under the guideline recommendations. Implementation of the Society of Surgical Oncology and American Society of Radiation Oncology consensus guideline holds great potential to optimize resource use. Application of the guideline to a retrospective cohort at our institution would have decreased the overall re-excision rate by 5.6% and reduced costs by nearly $200

    Scedosporium apiospermum is an emerging opportunistic filamentous fungus, which is notorious for its high levels of antifungal-resistance. It is able to cause localized cutaneous or subcutaneous infections in both immunocompromised and immunocompetent persons, pulmonary infections in patients with predisposing pulmonary diseases and invasive mycoses in immunocompromised patients. Subcutaneous infections caused by this fungus frequently show chronic mycetomatous manifestation. We report the case of a 70-year-old immunocompromised man, who developed a fungal mycetomatous infection on his right leg. There was no history of trauma; the aetiological agent was identified by microscopic examination and ITS sequencing. This is the second reported case of S. apiospermum subcutaneous infections in Hungary, which was successfully treated by surgical excision and terbinafine treatment. After 7 months, the patient remained asymptomatic. Considering the antifungal susceptibility and increasing incidence of the fungus, Scedosporium related subcutaneous infections reported in the past quarter of century in European countries were also reviewed. Corticosteroid treatment represents a serious risk factor of S. apiospermum infections, especially if the patient get in touch with manure-enriched or polluted soil or water. Such infections have emerged several times in European countries in the past decades. The presented data suggest that besides the commonly applied voriconazole, terbinafine may be an alternative for the therapy of mycetomatous Scedosporium infections.

    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.

    Full Text Available In the midst of on-going non-illicit practice of silicone or paraffin injection to enlarge penis, the author reported 3 cases of surgical treatment to resurface the body of the penis after excision of the destructed penile skin using full thickness skin graft. The skin excision was performed technically through penile body degloving procedure. Full thickness skin graft was then applied as a single sheet donor tissue to cover the denuded penile body spirally. The full thickness graft, which is relatively easy to be performed, is no doubt much thinner than a skin flap, while it also bears a smaller degree of secondary contraction than split skin graft. The color of the skin is considerably matched as it comes from the groin, which is a nearby area of penis. The size and skin sensitization of the penis looks to be natural. The only disadvantage is the common possibility of either spiral or circular junctional scar in between graft edges and between the graft and the penile mucosa and skin to develop hypertrophic scar. However, this possible scar problem applies also to any other surgical scar with any donor tissue. Fortunately, the 3 cases posed no scar problem and normal appearance. All the patients have also regained their normal sexual function. (Med J Indones 2011; 20:222-5Keywords: full thickness skin graft, paraffinoma, siliconoma, sexual function

    Subungual keratoacanthoma (SUKA) is a rare form of keratoacanthoma, with the majority of the lesions appearing as rapidly growing, painful hyperkeratotic masses located under the distal nail plate of the thumb. In some cases, SUKA causes damage to the underlying bone. The first case presented here was treated by surgical excision alone, and human papilloma virus (HPV) type 6 was detected in the tissue samples. The second case was treated by surgical excision plus curettage; however, HPV was not detected, and tumor cells were not found in the curettage material. There was near complete improvement in both the clinical appearance and the distal phalanx destruction, with no recurrence at the final follow-up in either patient (30 and 14 months, respectively). Overall, simple excision alone or in combination with curettage seemed to be sufficient in the treatment of SUKA; however, the etiopathogenetic role of HPV in SUKA remains controversial, as in its classical form.

    2011-11-01

    Full Text Available Purpose: To describe a reconstructive technique of the superior eyelid with flaps and free grafts after excision of a basal cell carcinoma. Methods: Single case report of a 79-year-old woman who presented to our hospital with a basal cell carcinoma of the upper eyelid margin with initial erosion. Results: A large and full-thickness excision of the carcinoma was performed. The reconstruction technique should be customized to the individual patient. In this case, the use of a full-thickness tarsal graft from the contralateral upper eyelid, followed by an ipsilateral bipedicled flap and finally by a skin graft, was an effective surgical procedure, performed in one stage, without complications, and with good functional and esthetic results. Conclusions: Malignant neoplasms represent the leading cause of plastic reconstruction in the orbital region. Surgical techniques must be individualized for each patient and for each type of carcinoma. Reconstructive techniques with free grafts and flaps yield excellent results in the orbital region, particularly when some advice and a few fundamental rules are followed, namely accurate hemostasis of the receiving graft bed by moderate use of diathermy, careful suturing of the edges, and application of a compressive dressing for at least 4 days. Postoperative complications are very rare.

    Purpose: To review and describe our institution's outcomes in patients treated with external beam radiotherapy after keloid excision. Methods and Materials: This was a retrospective study. Patients who received radiotherapy between July 1994 and January 2004 after keloid excision were identified. A questionnaire was mailed regarding sociodemographic factors, early and late radiation toxicities, the need for additional therapy, and satisfaction level. All patients had received a total of 15 Gy in three daily 5-Gy fractions. Treatment started within 24 h after surgery and was delivered on a Siemens orthovoltage machine. The data were analyzed using the STATA statistical package. Results: A total of 234 patients were approached. The response rate was 41%, and 75% were female. The mean age was 36.5 years (range, 16-69 years). The patients were mainly of European (53.1%) or African (19.8%) descent. For early toxicity outcomes, 54.2% reported skin redness and 24% reported skin peeling. For late toxicity outcomes, 27% reported telangiectasia and 62% reported permanent skin color changes. No association was found with gender, skin color, or age for the late toxicity outcomes. Of the patients responding, 14.6% required adjuvant treatment. On a visual scale of 1-10 for the satisfaction level, 60% reported a satisfaction level of ≥8. Telangiectasia was the most significant predictor of a low satisfaction level (≤3, p < 0.005). Conclusion: The results of our study have shown that orthovoltage-based radiotherapy after surgical excision for keloids is a good method for the prevention of relapse. It is well tolerated, causes little toxicity, and leads to a high patient satisfaction level

    Bilateral axillary hidradenitis is a chronic, suppurative, and scarring disease that is most effectively treated by complete excision of all hair-bearing tissues. We assessed our staged procedure for excision and placement of a split-thickness skin graft for bilateral axillary hidradenitis in terms of costs, outcomes, and timing of excision. An IRB approved retrospective case analysis was performed on patients that underwent bilateral axillary hidradenitis skin excision with eventual placement of split-thickness skin grafting using the current LSUHSC/University Health hidradenitis surgical treatment protocol. Using ICD-9 codes (705.83) and CPT codes (11041, 11042, 11451, 11600, 11601, 11602, 11603, 11604) we reviewed cases performed at our institution from 1 January 2008 to 24 Febuary 2014 and we selected patients based on bilateral axillary involvement (alone) and >1 year history of active disease. Patients were excluded if resection of tissue encompassed regions outside of the immediately adjacent axillary. A total of seven patients matching criteria for bilateral axillary hidradenitis were selected for analysis. Clinical course, cost and surgical techniques were assessed. Of the seven patients, six required admission throughout their treatment due to lack of funding making use of negative pressure wound therapy at home not possible. These patients stayed an average of 10 days with a mean hospital charge of $35,178 and a mean hospital provider charge of $10,019. No recurrence was demonstrated. All patients attained full range of motion, post grafting. No patient required a further operation due to graft failure. Split-thickness skin grafting without use of bilayer dermal regenerative templates yielded definitive results with acceptable cosmesis and functionality, without the added cost of treatments such as a bilayer dermal regenerative template.

    To evaluate the clinical course after early surgical treatment with excision of retinal hemangioblastomas (RHs) before development of major complications. Interventional case series of four eyes (four patients) with a peripheral RH that had not yet been treated by laser or cryotherapy prior to surgery. All eyes underwent 23-gauge vitrectomy with lesion excision. One patient underwent ligation of the feeder vessel prior to lesion excision. Best-corrected visual acuity and clinical course were assessed during a follow-up period of at least 4 years. Four patients (mean age 27.3 years; range 19-32) were included, of whom two had von Hippel-Lindau syndrome. Visual acuity improved in three patients (mean 4.8 lines; range 3-10) and remained stable at 0.0 logMAR in one patient. There were no intraoperative complications. Postoperative complications included transient mild vitreous haemorrhage (n = 2), and local epiretinal membrane formation at the excision location (n = 1). At 4 years postoperatively, there were no long-term complications. There was one case of a new lesion, which was effectively treated with laser. Vitrectomy with RH excision seems to be an effective approach for larger RHs and could be considered an early treatment option in selected cases. Postoperative complications were limited in scope of this case series. Important points to consider during vitrectomy are effective closure of feeder and draining vessels as well as complete removal of posterior hyaloid and epiretinal membranes in order to avoid postoperative vitreous haemorrhage and proliferative vitreoretinopathy. © 2016 Acta Ophthalmologica Scandinavica Foundation.

  3. Circumferential scouting punch biopsies to delineate surgical margin for dermatofibrosarcoma protuberans

    Directory of Open Access Journals (Sweden)

    Tsung-Mao Huang

    2012-03-01

    Full Text Available Dermatofibrosarcoma protuberans (DFSP is an uncommon soft-tissue tumor involving the dermis and subcutaneous tissue with a high local recurrence rate after standard excision. Mohs micrographic surgery offers a lower recurrence rate. However, the procedure requires multiple stages of excision with intraoperative histopathological mapping, which is time consuming and expensive. We report our experience of using circumferential scouting punch biopsy technique in five patients to determine in advance the resection margins for DFSP prior to wide excision. Multiple 4 mm punches, usually eight in number, were performed 1–2.5 cm around the palpable borders of DFSP to delineate the resection margins in five consecutive patients. Tumors were excised at a later date along the margin defined by these biopsies and the wounds were repaired with skin graft. The operation was completed in 2 hours in all cases excluding one that required frozen sections for deep margin. No recurrence was noted 2–10 years after the operations. The results suggest that circumferential scouting punch biopsies before wide excision may be an alternative method to define the resection margins for DFSP when Mohs surgery is not available.

    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.

    In the surgical treatment of rectal cancer, a clear circumferential resection margin and distal resection margin should be obtained. The aim of this study was to determine the morbidity, mortality, survival outcome, and local failure after total mesorectal excision (TME) in the surgical treatment of rectal cancer. This retrospective study was conducted on 101 patients treated for rectal cancer using low anterior resection (LAR), abdominoperinial resection (APR), or Hartmaan's technique. In all operative procedures, total mesorectal excisions (TMEs) were done. The patients were treated from November 2000 to April 2011 in the South Egypt Cancer Institute (SECI) of Assuit University (Egypt). Neo-adjuvant therapy was given to those patients with serosalin filtration, lymph node involvement, and sexual and urinary function impairment. Data were analyzed using IBM-SPSS version 21, and survival rates were estimated using the Kaplan-Meier method. One hundred one patients were evaluable (61 males, 40 females). Regarding the operative procedure used, it was: (APR), LAR, Hartmaan's technique in 15.8%, 71.3%, and 12.9% of patients, respectively. Operation-related mortality during the 30 days after surgery was 3%. The operations resulted in morbidity in 25% of the patients, anastomotic site leak in 5.9% of the patients, urinary dysfynction in 9.9% of the patients, and erectile dysfunction in 15.8% of the male patients. Regarding safety margin, the median distances were distal/radial margin, 23/12 mm, distal limit 7 cm. Median lymph nodes harvest 19 nodes. Primary tumor locations were anteriorly 23.8%, laterally 13.9%, posteriorly 38.6%, and circumferential 23.8%. Protective stoma 16.8%. Primary Tumor TNM classification (T1, T2, T3, and T4; 3, 28.7, 55.4, and 12.9%, respectively). Nodes Metastases (N0, N1, and N2; 57.4, 31.7, and 10.9%, respectively).

    To quantify the impact of excision margins on disease-specific survival of patients with primary cutaneous melanoma. Current guidelines recommend narrow margins for the treatment of primary melanoma, although available evidence on this subject is not unequivocal and not always appropriately analyzed. A systematic review of randomized controlled trials (RCT) addressing the issue of wide versus narrow excision margins was performed. Meta-analysis methods for time-to-event data were used to extract hazard ratios(HR) and their 95% confidence intervals (CI) from eligible studies, and ultimately to estimate the summary effect of excision margins on patients' survival. The 5 eligible RCT enrolled a total of 3295 patients who were allocated to wide (3-5 cm) or narrow (1-2 cm) excision of their primary tumor. The data of locoregional disease-free (LDFS), disease-free (DFS),disease-specific (DSS), and overall (OS) survival were available for 3, 5, 3, and 5 RCT, respectively. The meta-analysis suggested that narrow margins might be associated with an increased risk of both locoregional disease recurrence (HR: 1.30, CI: 1.07-1.57; P = 0.01) and death by disease (HR: 1.28, CI:1.07-1.53, P = 0.01). As regards DFS, the borderline disadvantage (HR:1.13, CI: 0.995-1.28; P = 0.06) becomes significant when considering RCT that enrolled patients with thicker melanoma (HR: 1.19, CI: 1.02-1.39, P =0.03). When death by any cause (OS) was analyzed, no risk difference was found. The lack of DSS data from all the available RCT does not allow to draw definitive conclusions. However, current evidence appears sufficient to question the common belief that narrow excision margins are as safe as wide margins in the management of primary melanoma, that calls for further investigation in this field.

    The purpose of the present work has been to evaluate surgical treatment of gynecomastia performed by liposuction combined with subcutaneous mastectomy. It was designed as a prospective consecutive registration of 21 patients (28 breasts) operated in a four month period. Treatment was done in local anaesthesia in the out-patient clinic. Treatment was in one patient complicated with a haematoma. In 86% of cases the patients were satisfied with the postoperative result. Liposuction combined with surgical excision of the gland performed as an out-patient treatment in local anaesthesia is followed by few complications and good cosmetic results.

    To analyze early postoperative period in patients with diffuse pulmonary emphysema after palliative surgical correction of respiratory failure. The study included 196 patients who underwent bullectomy (n=111) and surgical reduction of pulmonary volume (n=85). Overall morbidity and mortality were 40.8% and 12.2% respectively. Among patients older than 60 years these values were significantly higher (58.0% and 22.6% respectively). It was shown that age over 60 years is associated with high risk of complications and mortality after excision of large and giant bulls. In patients pulmonary volume. Selection of patients for palliative surgical correction of respiratory failure is generally corresponded to that for lung transplantation. However, these methods should be considered complementary rather competing.

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

    Clear cell hidradenocarcinoma (CCH) is an exceedingly rare and highly malignant tumor of the eccrine sweat glands. Its treatment is extremely difficult due to the characteristically aggressive clinical course including repeated local recurrence and uncontrollable distal metastasis coming along with a very poor prognosis. Most published case studies recommend a wide surgical excision followed by adjuvant conservative therapy, which is generally considered to be the standard treatment. Two cases of nodular CCH of the scalp either presenting as a singular primary lesion or at an already metastatic stage were analyzed retrospectively. Wide local excision of the tumor couldn't prevent the primary carcinoma from recurring and metastasizing. Both cases received various therapies but the results were unsatisfactory. Although most authors have recommended that early wide surgical excision of the tumor is a feasible therapeutic measurement, our results raise doubts on the efficacy of this treatment strategy. As alternative approaches (i.e. chemotherapy, radiotherapy) are similarly controversial, further studies and a wide exchange of clinical experiences are crucial.

    Next to surgical margins, yield of lymph nodes, and length of bowel resected, macroscopic completeness of mesorectal excision may serve as another quality control of total mesorectal excision (TME). In this study, the macroscopic completeness of laparoscopic TME was evaluated. A series of 25 patients with rectal cancer were managed laparoscopically (LTME) and included in this study. The pathologic specimens of the LTME group were prospectively examined and matched with a historical group of resection specimens from patients who had undergone open TME (OTME). The two groups were matched for gender and type of resection (low anterior or abdominoperineal resection). Special care was given to the macroscopic judgment concerning the completeness of the mesorectum. A three-grade scoring system showed no differences between the LTME and OTME groups. The current study supports the hypothesis that oncologic resection using laparoscopic TME is feasible and adequate.

    Purpose: To evaluate the long-term toxicity, cosmesis, and local control of accelerated partial breast irradiation with implant brachytherapy after wide local excision for Stage T1N0 breast cancer (BCa). Materials and Methods: Between 1997 and 2001, 50 patients with Stage T1N0M0 BCa were treated in a Phase I-II protocol using low-dose-rate accelerated partial breast irradiation with implant brachytherapy after wide local excision and lymph node surgery. The total dose was escalated in three groups: 50 Gy (n = 20), 55 Gy (n = 17), and 60 Gy (n = 13). Patient- and physician-assessed breast cosmesis, patient satisfaction, toxicity, mammographic abnormalities, repeat biopsies, and disease status were prospectively evaluated at each visit. Kendall's tau ({tau}{sub {beta}}) and logistic regression analyses were used to correlate outcomes with dose, implant volume, patient age, and systemic therapy. Results: The median follow-up period was 11.2 years (range, 4-14). The patient satisfaction rate was 67%, 67% reported good-excellent cosmesis, and 54% had moderate-severe fibrosis. Higher dose was correlated with worse cosmetic outcome ({tau}{sub {beta}} 0.6, p < .0001), lower patient satisfaction ({tau}{sub {beta}} 0.5, p < .001), and worse fibrosis ({tau}{sub {beta}} 0.4, p = .0024). Of the 50 patients, 35% had fat necrosis and 34% developed telangiectasias {>=}1 cm{sup 2}. Grade 3-4 late skin and subcutaneous toxicities were seen in 4 patients (9%) and 6 patients (13%), respectively, and both correlated with higher dose ({tau}{sub {beta}} 0.3-0.5, p {<=} .01). One patient had Grade 4 skin ulceration and fat necrosis requiring surgery. Mammographic abnormalities were seen in 32% of the patients, and 30% underwent repeat biopsy, of which 73% were benign. Six patients had ipsilateral breast recurrence: five elsewhere in the breast, and one at the implant site. One patient died of metastatic BCa after recurrence.

    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.

    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.

    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.

    Current standard of care for full-thickness burn is excision followed by autologous split-thickness skin graft placement. Skin grafts are also frequently used to cover surgical wounds not amenable to linear closure. While all grafts have potential to contract, clinical observation suggests that antecedent thermal injury worsens contraction and impairs functional and aesthetic outcomes. This study evaluates the impact of antecedent full-thickness burn on split-thickness skin graft scar outcomes and the potential mediating factors. Full-thickness contact burns (100°C, 30s) were created on the backs of anesthetized female Yorkshire Pigs. After seven days, burn eschar was tangentially excised and covered with 12/1000th inch (300μm) split-thickness skin graft. For comparison, unburned wounds were created by sharp excision to fat before graft application. From 7 to 120days post-grafting, planimetric measurements, digital imaging and biopsies for histology, immunohistochemistry and gene expression were obtained. At 120days post-grafting, the Observer Scar Assessment Scale, colorimetry, contour analysis and optical graft height assessments were performed. Twenty-nine porcine wounds were analyzed. All measured metrics of clinical skin quality were significantly worse (pskin graft quality, likely by multiple mechanisms including burn-related inflammation, microscopically inadequate excision, and dysregulation of tissue remodeling. A valid, reliable, clinically relevant model of full-thickness burn, excision and skin replacement therapy has been demonstrated. Future research to enhance quality of skin replacement therapies should be directed toward modulation of inflammation and assessments for complete excision. Copyright © 2016 Elsevier Ltd and ISBI.

    Chemical burns are rare but often lead to deep cutaneous lesions. Alkali agents have a deep and long lasting penetrating power, causing burns that evolve over several days. The local treatment for these patients is excision of the wound and split thickness skin graft. Early excision and immediate skin grafting of alkali burns are more likely to be complicated by graft failure and delayed wound healing. We propose a two-step method that delays skin grafting until two-three days after burn wound excision. Our population included 25 controls and 16 cases. Men were predominant with a mean age of 41.9 years. In 78% of cases, burns were located on the lower limbs. The mean delay between the burn and excision was 16.5 days. In cases, the skin graft was performed at a mean of 11.3 days after the initial excision. We did not unveil any significant difference between both groups for the total skin surface affected, topography of the burns and the causal agent. Wound healing was significantly shorter in cases vs controls (37.5 days vs 50.3 days; P<0.025). Furthermore, we observed a decreased number of graft failures in cases vs controls (13.3% vs 46.7%; P=0.059). Our study shows the relevance of a two-step surgical strategy in patients with alkali chemical burns. Early excision followed by interval skin grafting is associated with quicker wound healing and decreased rate of graft failure. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

    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.

  2. Repair of DNA-polypeptide crosslinks by human excision nuclease

    2006-03-01

    DNA-protein crosslinks are relatively common DNA lesions that form during the physiological processing of DNA by replication and recombination proteins, by side reactions of base excision repair enzymes, and by cellular exposure to bifunctional DNA-damaging agents such as platinum compounds. The mechanism by which pathological DNA-protein crosslinks are repaired in humans is not known. In this study, we investigated the mechanism of recognition and repair of protein-DNA and oligopeptide-DNA crosslinks by the human excision nuclease. Under our assay conditions, the human nucleotide excision repair system did not remove a 16-kDa protein crosslinked to DNA at a detectable level. However, 4- and 12-aa-long oligopeptides crosslinked to the DNA backbone were recognized by some of the damage recognition factors of the human excision nuclease with moderate selectivity and were excised from DNA at relatively efficient rates. Our data suggest that, if coupled with proteolytic degradation of the crosslinked protein, the human excision nuclease may be the major enzyme system for eliminating protein-DNA crosslinks from the genome. damage recognition | nucleotide excision repair

    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.

    Full Text Available Background : Several blood conservation strategies have been tried with the purpose of reducing homologons blood transfusion. Patients & Methods : 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. Results : 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. Conclusion : We conclude

    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.

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.

    Full Text Available Purpose: The treatment of oral mucosal lesions and mucosal hypertrophy in particular, is most often achieved by an excision with or without covering the surface of the wound. The platelet rich fibrin membrane (PRFm is an autogenous product containing platelets and leukocytes and their secreted growth factors and cytokines. The purpose of the presented clinical case is to describe a new, recent technique used for the covering of mucosal wounds left after the removal of pathological lesions. Material and Methods: On a single patient mucosal hypertrophy was removed by an excision with scalpel and the resulting surgical wound was covered with an autogenous PRF membrane. Postoperatively the healing process was followed on the 7th, 14th and 30th day. Results: The healing period went smoothly with minimal postoperative discomfort and no complications. Conclusion: The results of the presented clinical case demonstrate that the PRF membrane can successfully be used to cover postoperative mucosal defects.

    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 the

    Elephantiasis nostras verrucosa (ENV) is a rare cutaneous sequela of chronic lymphedema. Treatment of ENV remains poorly elucidated but has historically involved conservative management aimed at relieving the underlying lymphedema, with a few cases managed by surgical intervention. We report a case of a 27-year-old male with primary lymphedema complicated by large painful ENV lesions on his left foot that we excised surgically with good functional and cosmetic results as validated by the patient. To our knowledge, this is the first report of a case of ENV with a pedunculated morphology and the presence of a deep invasive stalk. Copyright © 2015 American College of Foot and Ankle Surgeons.

    Improvement in any human activity is preconditioned by inspection of results and providing feedback used for modification of the processes applied. Comparison of experts experience in the given field is another indispensable part leading to optimisation and improvement of processes, and optimally to implementation of standards. For the purpose of objective comparison and assessment of the processes, it is always necessary to describe the processes in a parametric way, to obtain representative data, to assess the achieved results, and to provide unquestionable and data-driven feedback based on such analysis. This may lead to a consensus on the definition of standards in the given area of health care. Total mesorectal excision (TME) is a standard procedure of rectal cancer (C20) surgical treatment. However, the quality of performed procedures varies in different health care facilities, which is given, among others, by internal processes and surgeons experience. Assessment of surgical treatment results is therefore of key importance. A pathologist who assesses the resected tissue can provide valuable feedback in this respect. An information system for the parametric assessment of TME performance is described in our article, including technical background in the form of a multicentre clinical registry and the structure of observed parameters. We consider the proposed system of TME parametric assessment as significant for improvement of TME performance, aimed at reducing local recurrences and at improving the overall prognosis of patients. rectal cancer total mesorectal excision parametric data clinical registries TME registry.

    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.

    The giant intracranial meningioma (GIM) constitutes a different spectrum of brain tumors that invade the vital neurovascular structures, which makes the primary mode of treatment, surgery, a technically challenging one. The surgery for GIM is unique because of the large size of the tumor, prominent vascularity, entangling and limited visualization of various neurovascular structures, and severe cerebral edema. This study reports the authors surgical experience of 80 GIM cases, the operative challenges and surgical outcome. A retrospective analysis of 80 patients with histologically proven meningioma (≥5 cm) who underwent surgical treatment at Louisiana State University Health Sciences Center (Shreveport, Louisiana, USA) over a 20-year period (1995-2015) is presented. The clinical and radiologic data were collected from the hospital database. The tumors were categorized into histologic groups according to World Health Organization (WHO) classification. The relevant statistical analysis of the study was conducted using SPSS software, version 22.0. The study included 27 male patients (33.8%) and 53 female patients (66.3%). The mean age of the cohort was 56 years (56.3±16.1). The mean size of the tumor was 56.4 ±4 mm with a range from 50 mm to 84 mm. Skull base was the most common location of GIM (57 patients, 71.3%). Simpson grade 1 excision was achieved in 9 patients (11.3%), whereas grade 2 excision was achieved in 57 patients (71.3%); 80% of the tumors belonged to WHO grade 1. The operative mortality was seen in 4 patients (5%). Regression analysis showed that age, sex, location of the tumor, neuronavigation, Simpson grade of excision, and histology of tumor were the factors that significantly affected the recurrence-free survival (RFS). The surgery for GIM is unique in different ways. As surgery for GIM is formidable, radiologic characteristics can be useful adjuncts for planning an effective and safe surgical strategy. The factors such as young age, male sex

  19. 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...

    2017-01-01

    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.

    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 Non-transecting anastomotic urethroplasty – is three types of urethroplasty, which are united on the principle resection of bulbar urethra with sparing of corpus spongiosum and antegrade blood flow through it. The article describes the surgical technique of urethroplasty: dorsal strictureplasty by Heineke–Mikulicz; strictureplasty by Mundy; vessel-sparing anastomotic urethroplasty by Jordan. Obligatory conditions of the non-transecting anastomotic urethroplasty are a non traumatic etiology, length of the stricture not more than 1–1.5 cm, and its localization in the proximal bulbar urethra. Strictureplasty by Heineke–Mikulicz is a dorsal longitudinal incision of the urethra on the area of stricture and subsequent suturing the defect transversely. Strictureplasty by Mundy is a dorsal longitudinal urethrotomy, excision of the affected mucosa inside the lumen of the urethra and transversely urethral closure according to Heineke–Mikulicz, s principle. Vessel-sparing anastomotic urethroplasty by Jordan is circular excision of the urethral mucosa without crossing of corpus spongiosum and incoming into it bulbar arteries and thereby preserving the antegrade blood flow through the urethra.

    2015-01-01

    Full Text Available The surgical management of maxillary pathosis results in direct communication between the oral and nasal cavity, imposing problems such as nasal regurgitation, unintelligent speech, difficulty in deglutition and compromised esthetics. A restoration of these defects is not always possible surgically, but prosthetic rehabilitation is an established treatment modality. Early rehabilitation can improve the quality of life and reduce the psychological trauma caused by surgical excision. Surgical and interim obturators placed during the initial phase can improve the outcome of the definitive prosthesis. This article presents a case report of a patient with partial maxillectomy who has been rehabilitated with a delayed surgical and an interim obturator.

    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 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.

    2006-01-01

    Purpose: To identify factors in breast cancer patients that predict the pathologic results of re-excision for close or positive margins and to determine the effect on local control. Methods and Materials: We divided 1,044 patients with Stage I-II breast cancer with a close (≤2 mm) or positive margin after initial excision into three groups. Group 1 included 199 patients without additional excision, Group 2 included 546 patients with re-excision found to be free of cancer, and Group 3 included 299 patients with re-excision and residual cancer. All patients were treated with radiotherapy with a median follow-up of 6.7 years. Results: The 10-year local control rate was 95% for Group 1 and 94% for Groups 2 and 3 (p = 0.788). Of the 846 patients, 65% had no residual disease on re-excision and 35% did have residual tumor. The factors significantly associated with positive re-excision findings were initial positive margins, positive nodes, Stage T2 tumor, and an extensive intraductal component. The 10-year local control rate was 95% for Group 2 vs. 91% for Group 3 (p = 0.038). Conclusion: The low recurrence rates seen in this study suggest that selected patients with non-negative margins, particularly those with a low risk of having residual disease at re-excision, may be treated with radiotherapy

    Numerous methods of gynecomastia repair have been described to accomplish removal of breast tissue. Our multimodality surgical approach for the treatment of gynecomastia combines the use of power-assisted superficial cross-chest liposuction with direct pull-through excision of the breast parenchyma under endoscopic supervision. Seventeen patients, aging 17-39, underwent this multimodality approach. According to Simon's grading, 3 patients had grade 1, 5 had grade 2a, 6 had grade 2b, and 3 had grade 3 gynecomastia. Power-assisted liposuction was performed with a 3- or 4-mm triple-hole cannula inserted through the contralateral periareolar medial incision to suction the contralateral prepectoral fatty breast. At the end of the liposuction, the fibrous tissue was easily pulled through the ipsilateral stab wound and excised under endoscopic control. Follow-up time ranged from 6 to 34 months. The amount of fat removed by liposuction varied from 100-800 mL per breast, and the amount of breast parenchyma removed by excision varied from 20-110 g. All patients recovered remarkably well. No complications were recorded. All patients were satisfied with their results. This technique enables an effective treatment of both the fatty and fibrous tissue of the male breast and avoids skin redundancy due to skin contraction. A smooth masculine breast contour is consistently achieved without the stigma of this type of surgery.

    From 1973 to 1988 in the Dermatological Surgery Unit of the 1st Department of Dermatology of the Silesian School of Medicine in Katowice 82 patients were treated surgically for keratoacanthoma. In 76 patients the defect was closed by simple bringing closer the edges or by local plastic surgery, in 6 patients it was covered with free full-thickness skin grafts. The preparations of the excised tumors from various places were examined histologically. In three cases the texture of carcinoma spinocellulare was found in the base of the tumor. In 98% of the patients the wounds healed by first intention.

    2012-01-01

    Oral submucous fibrosis is a chronic debilitating disease characterized by gradually increasing fibrosis of the oral cavity and pharynx, mainly the buccal mucosa, resulting in trismus. The highest incidence of oral submucous fibrosis is seen in South India due to various deleterious habits. In spite of the numerous medical modalities employed in the management of oral submucous fibrosis, occasionally surgical intervention becomes inevitable. Various surgical approaches have been used to reconstruct the surgical defects following excision of fibrous bands. Full thickness skin grafts have been described in the literature with variable outcomes. In the present study a 38-year-old male presented with severe oral submucous fibrosis of the buccal mucosa, which was successfully treated and reconstructed using full thickness skin graft with stable functional result after one year of treatment. An integrated review of the literature regarding etiology, histopathology, diagnostic, and treatment modalities of the disease follows. PMID:23304568

  10. Trends in the Surgical Correction of Gynecomastia.

    2015-05-01

    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.

    The objective of this study was to investigate the clinical characteristics and surgical modality of plasma cell mastitis (PCM). A total of 93 breasts of 91 female patients with PCM from June 2003 to June 2010 (unilateral in 89 patients and bilateral in two patients) were investigated in this study. All breasts were divided into two groups: the direct excision group (DE group) received focused excision and nipple retraction correction; and the incision drainage group (ID group) received these procedures only in the event of failing at least two incision drainages. Clinical characteristics, extent of excision, and prognosis were compared between two groups. There were 53 breasts in the DE group and 40 breasts in the ID group. No significant differences were noted in the number of retracted nipples and abscesses in the first visit or extent of disease between two groups (P > 0.05). However, during surgery, 3.85 ± 0.97 abscesses per breast were detectable in the ID group, which was significantly higher than 1.21 ± 0.06 abscesses per breast in the DE group. The ID group had significantly higher inflammation and excised extent compared with the DE group (P culture was negative for pus of 39 nonrupturing abscesses. Congenital nipple retraction may be the primary cause of PCM. Early and complete focused excision and nipple retraction correction are effective treatment methods.

    Full Text Available This research simulates the effect of imposing excise tax on plastic container of drinks towards economic performance of beverage industry in Indonesia and governmentâ˘A ´Zs tax revenue. The results showed that by imposing excise tax on plastic cups and plastic bottles the government would lose tax revenue from value added tax (PPN and corporate income tax (PPh badan more than they gain additional revenue from excise tax. Hence, imposing excise tax on drink containers should serve a clear purpose and an undeniable reason. This paper recommends the government to develop proper excise infrastructure to extend the goods or services to be taxed. This paper also recommends the required stages for extending the excise tax.

    2011-08-01

    Inguinal hernia repair is one of the most common operation in surgical practice. Despite its common occurrence, hernia often poses a surgical dilemma even for a skilled surgeon. The unexpected hernial content constitutes one of these cases. Although the often-reported, unusual contents of a hernia sac include ovary, fallopian tube, vermiform appendix, Meckel diverticulum, and urinary bladder, the herniation of a large ovarian cyst into the inguinal canal has been hardly reported. Majority of the ovarian cysts are asymptomatic or present with vague lower abdominal pain, whereas the presentation of a large ovarian cyst as an inguinolabial swelling as in our patient is extremely rare. We present here one of the few reported cases of a laparoscopic excision of a large ovarian cyst herniating into the inguinal canal and discuss the pathogenesis of an ovarian cyst as hernial content, the advantages and concerns of a laparoscopic approach in resecting large ovarian cysts, and simultaneous management of the inguinal hernia.

    Correction of gynecomastia in males is a frequently performed aesthetic procedure. Various surgical options involving the removal of excess skin, fat, or glandular tissue have been described. However, poor aesthetic outcomes, including a flat or depressed pectoral area, limit the success of these techniques. The authors sought to determine patient satisfaction with the results of upper chest augmentation by direct intrapectoral fat injection in conjunction with surgical correction of gynecomastia. In this prospective study, 26 patients underwent liposuction and glandular excision, glandular excision alone, or Benelli-type skin excision. All patients received intramuscular fat injections in predetermined zones of the pectoralis major (PM). The mean volume of fat injected was 160 mL (range, 80-220 mL per breast) bilaterally. Patients were monitored for an average of 16 months (range, 8-24 months). Hematoma formation and consequent infraareolar depression was noted in 1 patient and was corrected by secondary lipografting. Mean patient satisfaction was rated as 8.4 on a scale of 1 (unsatisfactory) to 10 (highly satisfactory). Autologous intrapectoral fat injection performed simultaneously with gynecomastia correction can produce a masculine appearance. The long-term viability of fat cells injected into the PM needs to be determined. 4 Therapeutic. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

    2018-05-01

    Vocal fold cysts are benign mid-membranous lesions of the true vocal fold, classified as mucus retention or epidermal inclusion cysts. Treatment is surgical excision with or without postoperative voice therapy. A retrospective review was performed of the demographics, treatment approach, and outcomes of patients treated for vocal fold cysts between 2009 and 2014. Voice Handicap Index (VHI)-10 scores before and after treatment were compared using the Wilcoxon Rank-Sum test and the two-tailed Student's t test. Videostroboscopy examinations were reviewed for posttreatment changes in vibratory characteristics of the vocal folds. Twenty-five patients were identified, and one was excluded for incomplete records. Mean age was 41.9 years (66.7% female), and mean follow-up time was 5.58 months. Microflap excision was pursued by 21/24 (87.5%) patients, with 14 patients (58.3%) undergoing perioperative voice therapy. One cyst recurred. Two patients elected for observation, and their cysts persisted. VHI-10 decreased from 23.8 to 6.6 (P Vocal fold cysts impact mucosal wave and glottic closure. Surgical excision resulted in low rates of recurrence, and in improvement in the mucosal wave and VHI-10. Perioperative voice therapy did not offer a significant benefit. Mucus retention cysts were the majority, in contrast to other published studies. Copyright © 2018 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Between 1987 and 1997, the tobacco industry used the issue of cigarette excise tax increases to create a political partnership with the Coalition of Labor Union Women (CLUW), a group representing female trade unionists in the U.S. This paper documents how the industry created this relationship and the lessons tobacco-control advocates can learn from the industry’s example, in order to mitigate possible unintended consequences of advocating excise tax increases In 1998, under the terms of the Master Settlement Agreement, the tobacco industry began making documents produced in litigation available publicly. Currently, approximately 50 million pages are available online, including substantial documentation of the industry–CLUW relationship. For this study, a comprehensive search of these documents was conducted. The tobacco industry encouraged CLUW’s opposition to excise tax increases by emphasizing the economic regressivity of these taxes, discussing excise taxes generically to deflect attention from cigarettes, and encouraging opposition to earmarking cigarette taxes to pay for specific programs. In addition, CLUW received at least $221,500 in financial support between 1987 and 1997 and in-kind support for its conferences, membership materials, and other services. Excise tax increases, if pursued without considering the impacts they may have on low-SES populations, may have unintended consequences. In this case, such proposals may have helped to create a relationship between CLUW and the tobacco industry. Because excise taxes are endorsed in the Framework Convention on Tobacco Control, tobacco-control advocates must understand how to build relationships with low-SES populations and mitigate potential alliances with the tobacco industry.

    Full Text Available Merkel’s cell carcinoma is a rare cutaneous tumor that can affect a wide variety of sites throughout the body. Commonly, it affects the skin alone and the management of limited disease can be confusing since the natural history of the disease involves distant metastasis. Traditional management has required wide local excision with negative margins of resection. We describe a case treated with local therapy alone and review the literature to suggest that complete microscopic excision may not be required if adjuvant radiotherapy is used.

    Lasers have made tremendous progress in the field of dentistry and have turned out to be crucial in oral surgery as collateral approach for soft tissue surgery. This rapid progress can be attributed to the fact that lasers allow efficient execution of soft tissue procedures with excellent hemostasis and field visibility. When matched to scalpel, electrocautery or high frequency devices, lasers offer maximum postoperative patient comfort. Four patients agreed to undergo surgical removal of benign lesions of the oral cavity. 810 nm diode lasers were used in continuous wave mode for excisional biopsy. The specimens were sent for histopathological examination and patients were assessed on intraoperative and postoperative complications. Diode laser surgery was rapid, bloodless and well accepted by patients and led to complete resolution of the lesions. The excised specimen proved adequate for histopathological examination. Hemostasis was achieved immediately after the procedure with minimal postoperative problems, discomfort and scarring. We conclude that diode lasers are rapidly becoming the standard of care in contemporary dental practice and can be employed in procedures requiring excisional biopsy of oral soft tissue lesions with minimal problems in histopathological diagnosis.

    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

    2016-09-01

    Full Text Available Objective: Tragus is a part of the external ear that develops from the first branchial arch. Accessory ear is a congenital external ear anomaly and has skin elevation containing remnant cartilage. The auricle develops between the 4th and 12th week of the embryonic stage, which groove the tissue from the 1st and 2nd branchial arches. Histologically, the lesions include a rugated epidermis with a thin layer stratum corneum, tiny mature hair follicles, fat lobules, and connective tissue framework that may include a central cartilage core. The aim of this study was to evaluate the accessory tragus lesions with our clinical surgical treatment results. Material and Methods: Lesions usually located anterior to the tragus and along an imaginary line drawn from the tragus to the angle of the mouth. Twelve patients admitted to our clinic between October 2011 and November 2014 were included in this study. Results: Seven boys and five girls between two–13 years old underwent operation. In total, 28 accessory ears were excised. No complications were observed during the procedure, and no complaints were noted in the postoperative period. Conclusion: Generally, limited anomaly is associated with the first and second branchial arch anomalies. Surgical excision is the standard treatment for the lesions which usually due to the esthetic concerns.

    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.

    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.

    During a period of 10 years (1977-1986) 40 cases of tumour of the pineal region have been treated at the Istituto Neurologico "C. Besta"-of Milan. Out of these 40 cases, 27 (67.5%) were in the paediatric (10-15 years) or juvenile (15-20 years) age at the time of operation. Since 1983 a specific diagnostic and therapeutic protocol has been adopted and thereafter direct surgical removal of the tumour was performed only when the neuroradiological investigations were highly suggestive of a benign extrinsic lesion. Sixteen cases in this series underwent direct surgical removal; in the remaining 24 cases stereotactic biopsy of the tumour was performed in the first instance. On the basis of the histological diagnosis obtained by this procedure surgical excision of the tumour (9 cases) or radiotherapy (15 cases) was then performed. 25 cases underwent surgical removal of the lesion. In all the cases the infratentorial supracerebellar approach as introduced by Krause and then modified by Stein was adopted. On analysis of the data of this series it was observed that in 25% of the cases completely benign resectable tumours were found; in 25% of the cases astrocytoma (grade I-II) which could be treated at least by partial removal were present; in 30% of the cases radiosensitive lesions were encountered. In the remaining 20% of the cases highly malignant tumours were found which should be treated only by radiotherapy and/or chemotherapy.

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

    2017-06-01

    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.

    effects on five-year disease-free survival (OR 1.02; 95% CI 0.76 to1.38, 4 studies, N = 943). The estimated effects of laparoscopic and open TME on local recurrence and overall survival were similar, although confidence intervals were wide, both with moderate quality evidence (local recurrence: OR 0.89; 95% CI 0.57 to1.39 and overall survival rate: OR 1.15; 95% CI 0.87 to1.52). There was moderate to high quality evidence that the number of resected lymph nodes and surgical margins were similar between the two groups.For the short-term results, length of hospital stay was reduced by two days (95% CI -3.22 to -1.10), moderate quality evidence), and the time to first defecation was shorter in the LTME group (-0.86 days; 95% CI -1.17 to -0.54). There was moderate quality evidence that 30 days morbidity were similar in both groups (OR 0.94; 95% CI 0.8 to 1.1). There were fewer wound infections (OR 0.68; 95% CI 0.50 to 0.93) and fewer bleeding complications (OR 0.30; 95% CI 0.10 to 0.93) in the LTME group.There was no clear evidence of any differences in quality of life after LTME or OTME regarding functional recovery, bladder and sexual function. The costs were higher for LTME with differences up to GBP 2000 for direct costs only. We have found moderate quality evidence that laparoscopic total mesorectal excision (TME) has similar effects to open TME on long term survival outcomes for the treatment of rectal cancer. The quality of the evidence was downgraded due to imprecision and further research could impact on our confidence in this result. There is moderate quality evidence that it leads to better short-term post-surgical outcomes in terms of recovery for non-locally advanced rectal cancer. Currently results are consistent in showing a similar disease-free survival and overall survival, and for recurrences after at least three years and up to 10 years, although due to imprecision we cannot rule out superiority of either approach. We await long-term data from a number of

    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.

    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.

    1977-01-01

    The behaviour of MUT-mutants of P.mirabilis to perform certain steps of excision repair after U.V.-irradiation is described. MUT-mutants introduce single-strand breaks in the DNA immediately after U.V.-irradiation, but their ability to excise pyrimidine dimers from the DNA is very diminished. Moreover, they are not able to accomplish the excision repair by rejoining of the single-strand breaks. The connection between the incomplete excision repair and the mutator phenotype of these mutants is discussed. (author)

    Aim: To investigate alternative possibilities for the intraoperative evaluation of surgical margins after bone resection utilizing more conventional hospital infrastructure technologies. Materials and methods: A small pilot study was performed using digital mammograph imaging intraoperatively on 16 surgical specimens of bone tumours or malignancies with bone infiltration of the head and neck area, with the aim of evaluating the resection margins. Results: In thirteen cases the intraoperative specimen images indicated clinically complete excision. In two cases incomplete resection or close proximity of margins was detected, which required additional resection. Conclusions: The results indicated that intraoperative specimen radiography can prove useful in evaluating completeness of excision. The significance of intraoperative assessment of surgical margin is of paramount importance when immediate reconstruction is performed. This proposed method is cheap, easy to perform and fast. Its cost–benefit ratio is superior than that of any other available technique. Intraoperative analysis of specimens with digital mammography imaging can potentially become a useful tool for immediate evaluation of osseous margins after resection

Methods: A retrospective case series was assembled from ADNIV patients in which there was fibrotic encapsulation of a fluocinolone acetonide implant. CAPN5 genotypes and surgical repair techniques were reviewed. Results: Two eyes of two ADNIV patients developed a fibrotic capsule over the fluocinolone acetonide implant. Both patients had Stage IV disease. Patient A had a c.731T > C mutation in the CAPN5 gene and patient B had a c.728G > T mutation. The fibrotic membrane was surgically excised and the implant function was restored. Conclusion: The exuberant fibrotic response in later stages of ADNIV may be resistant to local immunosuppression with steroids. Surgical excision of fibrotic membranes over FA implants can reestablish local steroid delivery in cases of severe proliferative vitreoretinopathy.

    2011-01-01

    The aim of this study was to evaluate the impact of radioguided occult lesion localization (ROLL) in the correct location and excision of malignant breast lesions, and analyze if these results are affected by the histology and tumor size. A total of 105 patients with occult breast lesions were studied. The mean age was 55 years. An intralesional dose of 18.5 MBq of 99mTc-labeled macroaggregated human albumin (AMA) was administered using stereotaxic mammography or ultrasound. Surgical resection was carried out with the help of a gammadetector probe. In the histological study, disease-free margin was defined by a distance between the tumor lesion and the surgical margin of more than 1 mm. The possible influence of tumor histology and lesion diameter with respect to free/affected margins was analyzed. Correct radiotracer placement was achieved in 100/105 of the cases (95.2%). In the remaining 5 cases (4.8%), radiotracer placement was incorrect, with 2 of them being malignant lesions that were found by macroscopic inspection, and the other 3 having benign pathology. Among the malignant lesions (44 cases), correct placement of the radiotracer was achieved in 42 cases (95.5%). Of these 42 malignant lesions, in which the ROLL was correctly performed, free surgical margins were obtained in 24 cases (57.1%), while the other 18 (42.9%) had infiltrated surgical margins. The most common histological type among the malignant lesions was invasive ductal carcinoma (71.4%). The histological types with an increased frequency of infiltration of surgical margins were invasive and microinvasive cancer (94.4%). All the affected margins were in lesions greater than 10 mm, and the highest incidence was in those between 20 and 30 mm (55.5%). In our experience, the advantages of the ROLL technique are a precise localization of malignant breast lesions (95.5%) and an increased probability of a complete excision with free margins in more than one half of them. Nevertheless, special

    Full Text Available Post-operative recurrence in mycetoma after adequate medical and surgical treatment is common and a serious problem. It has health, socio-economic and psychological detrimental effects on patients and families. It is with this in mind, we set out to determine the predictors of post-operative recurrence in mycetoma. The study included 1013 patients with Madurella mycetomatis causing eumycetoma who underwent surgical excision at the Mycetoma Research Centre, Khartoum, Sudan in the period 1991-2015. The clinical records of these patients were reviewed and relevant information was collected using a pre-designed data collection sheet. The study showed, 276 patients (27.2% of the studied population developed post-operative recurrence, 217 were males (78.6% and 59 were females (21.4%. Their age ranged between 5 to 70 years with a mean of 32 years. The disease duration at presentation ranged between 2 months and 17 years. The majority of the patients 118 (42.8% had mycetoma of 1 year duration. In this study, students were the most affected; 105 (38% followed by workers 70 (25.4%, then farmers 48(17.3%. The majority of the patients were from the Central Sudan 207 (75%, Western Sudan 53 (19.2% while 11 patients (4% were from the Northern part. Past history of surgical intervention performed elsewhere was reported in 196 patients (71.1%. Family history of mycetoma was reported in 50 patients (18.1%. The foot was the most affected site, 245 (88.7%, followed by the hand seen in 19 (6.8% patients and 44 (4.5% had different sites involvement. Most of the patients 258 (93.5% had wide local surgical excisions while 18 had major amputation. The model predicted that the certain groups have a high risk of recurrence, and these include patients with disease duration greater than 10 years and extra-pedal mycetoma. Patients with disease duration between [5-10] years, with pedal mycetoma, who had previous surgery, with positive family history and underwent wide local

    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.

    2013-05-01

    First branchial cleft (FBC) anomalies are uncommon. The aim of this retrospective clinical study is to describe our experience in dealing with these sporadically reported lesions. Eighteen cases presenting with various FBC anomalies managed surgically during an 8-year period at a tertiary referral medical institution were included. Ten were males (56 %) and eight females (44 %) with age range 3-18 years. Anomaly was right-sided in 12 cases (67 %). None were bilateral. Nine patients (50 %) had prior abscess incision and drainage procedures ranging from 1 to 9 times. Two also had previous unsuccessful surgical excisions. Clinical presentations included discharging tract openings in external auditory canal/conchal bowl (n = 9), periauricular (n = 6), or upper neck (n = 4); cystic postauricular, parotid or upper neck swellings (n = 5); and eczematous scars (n = 9). Three distinct anatomical types were encountered: sinuses (n = 7), fistulas (n = 6), and cysts (n = 5). Complete surgical excision required superficial parotidectomy in 11 patients (61 %). Anomaly was deep to facial nerve (FN) in three cases (17 %), in-between its branches in two (11 %) and superficial (but sometimes adherent to the nerve) in remaining cases (72 %). Continuous intraoperative electrophysiological FN monitoring was used in all cases. Two cases had postoperative temporary lower FN paresis that recovered within 2 months. No further anomaly manifestation was observed after 49.8 months' mean postoperative follow-up (range 10-107 months). This study has shown that awareness of different presentations and readiness to identify and protect FN during surgery is essential for successful management of FBC anomalies. Intraoperative electrophysiological FN monitoring can help in that respect.

  17. Investigational Paradigms in Downscoring and Upscoring DCIS: Surgical Management Review

    Full Text Available Counseling patients with DCIS in a rational manner can be extremely difficult when the range of treatment criteria results in diverse and confusing clinical recommendations. Surgeons need tools that quantify measurable prognostic factors to be used in conjunction with clinical experience for the complex decision-making process. Combination of statistically significant tumor recurrence predictors and lesion parameters obtained after initial excision suggests that patients with DCIS can be stratified into specific subsets allowing a scientifically based discussion. The goal is to choose the treatment regimen that will significantly benefit each patient group without subjecting the patients to unnecessary risks. Exploring the effectiveness of complete excision may offer a starting place in a new way of reasoning and conceiving surgical modalities in terms of “downscoring” or “upscoring” patient risk, perhaps changing clinical approach. Reexcison may lower the specific subsets' score and improve local recurrence-free survival also by revealing a larger tumor size, a higher nuclear grade, or an involved margin and so suggesting the best management. It seems, that the key could be identifying significant relapse predictive factors, according to validated risk investigation models, whose value is modifiable by the surgical approach which avails of different diagnostic and therapeutic potentials to be optimal. Certainly DCIS clinical question cannot have a single curative mode due to heterogeneity of pathological lesions and histologic classification.

    Discussion of the case reports of nine patients treated for desmoid tumours in the light of 62 such cases described in the relevant literature between 1975 and 1979. Among the patients analysed for the purposes of this study 9 had desmoid tumours treated at our clinic, while the other 60 cases were described in the relevant literature of the past 5 years. The methods used in this cohort were surgery for 37 patients, radiation for 20 patients, excision and post-surgical radiation for 5 patients and various other treatments for the remaining cases. Careful analysis and assessment of the results led to the conclusion that the vast majority of desmoids can be expected to show a satisfactory response to radiation, even though no clear therapeutic superiority could be established for either radical excision or radiation. If surgery is chosen, this should be carried out with the aim of removing all of the tumour. In circumstances precluding radical excision it appears wise to use post-surgical radiation. Follow-up examinations should be carried out in all patients so as to permit immediate diagnosis and treatment of any recurrent tumours. Each desmoid tumour is to be treated on an individual basis. In small tumours it is safer to remove not only the lesion itself but also some of the surrounding intact tissue, tumours at a more advanced stage should be subjected to radiation or both surgery and subsequent radiotherapy.

  19. Trends in the Surgical Correction of Gynecomastia

    2015-01-01

    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

    2017-03-01

    Full Text Available Objective: The webbed neck deformity or pterygium colli is the number one symptom of the Turner syndrome that leads the patient to consult a doctor. Various but rare surgical approaches have been described to correct this deformity. We reviewed our experience with the surgical correction of the pterygium colli.Methods: Through five clinical cases, we describe the surgical technique with a lateral approach which provides a better control of the operative site, allows for the excision of the underlying trapezial fascial web, thus preventing recurrence seen in the posterior approach, and restores a normal hairline. Results: No postoperative wound infection occurred. No recurrence was observed through 24 months. Three patients developed hypertrophic scars.Conclusion: The lateral approach associated with an advanced flap and a Z-plasty is an effective technique for correction of this neck deformity. The presence of a multidisciplinary team, formed with maxillofacial and plastic surgeons, endocrinologists and psychologists, is required to treat these patients allowing reintegration into society and family.

    With the introduction of total mesorectal excision (TME) for treatment of rectal cancer, the prognosis of patients with rectal cancer is improved. With this better prognosis, there is a growing awareness about the quality of life of patients after rectal carcinoma. Laparoscopic total mesorectal excision (LTME) for rectal cancer offers several advantages in comparison with open total mesorectal excision (OTME), including greater patient comfort and an earlier return to daily activities while preserving the oncologic radicality of the procedure. Moreover, laparoscopy allows good exposure of the pelvic cavity because of magnification and good illumination. The laparoscope seems to facilitate pelvic dissection including identification and preservation of critical structures such as the autonomic nervous system. The technique for laparoscopic autonomic nerve preserving total mesorectal excision is reported. A three- or four-port technique is used. Vascular ligation, sharp mesorectal dissection and identification and preservation of the autonomic pelvic nerves are described.

    Locally aggressive benign lesions of the jaws, such as odontogenic keratocysts and ameloblastomas, require complete excision in view of the high incidence of recurrence after incomplete surgical removal. Because of the limitations of conventional radiology as the sole technique for determining the extent of these lesions, the use of 99m-technetium-labeled bone-imaging agents is suggested. This method of defining the location of surgical margins is based on the agent's sensitivity as an indicator of subtle changes in bone metabolism. A case of an unusually large recurrent odontogenic keratocyst is presented in which the planning of the surgical procedure was predicated on the results of a bone scan of the jaws in addition to conventional radiology. This diagnostic procedure, especially when used in conjunction with conventional radiology, appears to be of considerable value in defining the extent of a variety of oral-maxillofacial bony lesions.

    Altogether 324 patients with skin basilomas, 559 with recurrent basiloma and 38 with squamous-cell carcinoma of the skin were treated by means of impulse neodymium laser radiation. A follow-up period was up to 7 years. It was shown that impulse laser radiation is a highly effective means of treating skin cancer, having a number of advantages over the radiation and surgical methods. Laser radiation is also highly effective in the treatment of basiloma relapses. If relapses accounted for by the development of a radioresistant tumour occur at the sites where surgical eXcision yields an unstatisfactory cosmetic effect, laser therapy should be considered a method of choice

    Idiopathic granulomatous lobular mastitis (IGLM) is a rare chronic inflammatory disease of the breast with obscure etiology that mimics invasive carcinoma both clinically and radiologically. The treatment of IGLM remains controversial. The aim of proper management is to use a combination of medical and surgical treatment of this benign condition to achieve a good cosmetic result and low recurrence rate. A retrospective analysis of 19 patients with IGLM is performed based on the findings of clinical, radiological, and pathological examinations. The results of two treatments are presented: medical treatment with oral corticosteroids, and consecutive surgical excision after a follow-up period of 20 months (range, 6-75 months). The majority of patients treated in this paper were young (mean, 34 years) parous women with a history of hormonal medication use. The main clinical finding is large, irregular, and painful mass. Hypoechoic lobulated, irregular tubular or oval shaped masses had been imaged by ultrasound. Mammographic findings were an ill-defined mass, enlarged axillary lymph nodes, asymmetric density, and architectural distortion. Diagnoses of IGLM had been established by cytological or histological examination. Symptoms subside and inflammatory changes regressed with medical treatment. The remaining lesions were excised by consecutive breast conserving surgery. The disease recurred in one patient during the follow-up period. IGLM is an inflammatory breast disease found in young women who present with a large painful irregular mass, which mimics carcinoma, as a physical change. Breast imaging modalities are not helpful to differentiate IGLM from invasive cancer. The correct diagnosis is established by cytological or histological examination. Medical treatment with corticosteroids provides significant regression of the inflammatory disease, allowing more conservative surgery. Consecutive surgical excision of the remaining lesions with good cosmetic results

  6. Surface characterization of retinal tissues for the enhancement of vitreoretinal surgical methods

    Science.gov (United States)

    Valentin-Rodriguez, Celimar

    Diabetic retinopathy is the most common ophthalmic complication of diabetes and the leading cause of blindness among adults, ages 30 to 70. Surgery to remove scar tissue in the eye is the only corrective treatment once the retina is affected. Visual recovery is often hampered by retinal trauma during surgery and by low patient compliance. Our work in this project aimed to improve vitreoretinal surgical methods from information gathered by sensitive surface analysis of pre-retinal tissues found at the vitreoretinal interface. Atomic force microscopy characterization of human retinal tissues revealed that surgically excised inner limiting membrane (ILM) has a heterogeneous surface and is mainly composed of globular and fibrous structures. ILM tissues also show low adhesion for clean unmodified surfaces as opposed to those with functional groups attractive to those on the ILM surface, due to their charge. Based on these observations, layer-by-layer films with embedded gold nanoparticles with a positive outer charge were designed. These modifications increased the adhesion between surgical instruments and ILM by increasing the roughness and tuning the film surface charge. These films proved to be stable under physiological conditions. Finally, the effect of vital dyes on the topographical characteristics of ILMs was characterized and new imaging modes to further reveal ILM topography were utilized. Roughness and adhesion force data suggest that second generation dyes have no effect on the surface nanostructure of ILMs, but increase adhesion at the tip sample interface. This project clearly illustrates that physicochemical information from tissues can be used to rationally re-design surgical procedures, in this case for tissue removal purposes. This rational design method can be applied to other soft tissue excision procedures as is the case of cataract surgery or laparoscopic removal of endometrial tissue.

    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.

    Experiments were performed to distinguish between two possible modes of hyperthermia-induced inhibition of thymine base damage excision from the DNA of CHO cells: (1) heat denaturation of excision enzyme(s) or (2) heat-induced alteration of the substrate for damage excision (chromatin). While hyperthermia (45 0 C, 15 min) had no apparent effect on the capacity of the excision enzymes to excise damage from DNA it had a dramatic effect (ca. 80% inhibition) on the ability of chromatin to serve as a substrate for unheated enzymes. These results suggest that hyperthermia-induced radiosensitization of CHO cells may be due primarily to lesions in the cellular chromatin

    To evaluate the efficacy and safety of the early surgical excision of periorbital haemangiomas with an ultrasonic scalpel in infants at risk of visual impairment. A retrospective analysis of 67 infants diagnosed to be at risk of amblyopia from periorbital haemangiomas, treated consecutively with the Dissectron between 1994 and 2005. Ophthalmic outcome parameters included the pre- and postoperative measurement of visual axis occlusion, strabismus, astigmatism, and degree of amblyopia. Visual performance showed an overall improvement of 30% following treatment. Seventy-six patients were found to have abnormal ophthalmic examinations preoperatively, compared to 46 following surgery. After surgery, visual axis occlusion decreased from 73 to 6%; amblyopia decreased from 67 to 22%, strabismus decreased from 26 to 18% and astigmatism (>onedioptre) decreased from 66 to 31%. Mean astigmatism values decreased from 3.5 to 1.9 dioptres. No new cases of astigmatism, strabismus or amblyopia were diagnosed postoperatively. Three minor complications resolved with conservative treatment. All patients were satisfied with the outcome of their surgery. Early surgical excision of periorbital haemangiomas using the Dissectron in infants with an established risk of visual impairment is a safe and effective alternative to pharmacological therapy. The use of the Dissectron is associated with reduced operative times and a shorter hospital stay.

    Surgical excision of tumor is a critical factor in the management of breast cancer. The most common surgical procedure is breast-conserving surgery. The surgeon's goal is to remove the tumor and a rim of healthy tissue surrounding the tumor: the surgical margin. A major issue in breast-conserving surgery is the absence of a reliable tool to guide the surgeon in intraoperatively assessing the margin. A number of techniques have been proposed; however, the re-excision rate remains high and has been reported to be in the range 30-60%. New tools are needed to address this issue. Optical coherence elastography (OCE) shows promise as a tool for intraoperative tumor margin assessment in breast-conserving surgery. Further advances towards clinical translation are limited by long scan times and small fields of view. In particular, scanning over sufficient areas to assess the entire margin in an intraoperative timeframe has not been shown to be feasible. Here, we present a protocol allowing ~75% of the surgical margins to be assessed within 30 minutes. To achieve this, we have incorporated a 65 mm-diameter (internal), wide-aperture annular piezoelectric transducer, allowing the entire surface of the excised tumor mass to be automatically imaged in an OCT mosaic comprised of 10 × 10 mm tiles. As OCT is effective in identifying adipose tissue, our protocol uses the wide-field OCT to selectively guide subsequent local OCE scanning to regions of solid tissue which often present low contrast in OCT images. We present promising examples from freshly excised human breast tissue.

    The current technique for locating nonpalpable breast lesions is wire localization (WL). Radioactive seed localization and intraoperative ultrasound were developed to improve difficulties with WL. The SAVI SCOUT surgical guidance system was developed to improve these methods. The SCOUT system is a non-radioactive, FDA-cleared medical device that uses electromagnetic wave technology to provide real-time guidance during excisional breast procedures. Consenting patients underwent localization and excision using an implantable electromagnetic wave reflective device (reflector) and a detector handpiece with a console. Using image guidance, the reflector was placed up to 7 days before the surgical procedure. The primary end points of the study were successful reflector placement, localization, and retrieval. The secondary end points were percentage of clear margins, reexcision rates, days of placement before excision, and physician comparison with WL. This study analyzed 50 patients. The reflectors were placed under mammographic guidance (n = 18, 36 %) or ultrasound guidance (n = 32, 64 %). Of the 50 patients, 10 (20 %) underwent excisional biopsy and 40 (80 %) had a lumpectomy. The lesion and reflector were successfully removed in all 50 patients, and no adverse events occurred. Of the 41 patients who had in situ and/or invasive carcinoma identified, 38 (93 %) had clear margins and 3 (7 %) were recommended for reexcision. These data suggest that the SCOUT system is safe and effective for guiding the excision of nonpalpable breast lesions and a viable alternative to standard localization options. A larger prospective, multi-institution trial of SCOUT currently is underway to validate these findings.

    Full Text Available ABSTRACT Dermoids are congenital lesions representing normal tissue in abnormal location. Orbital dermoid cysts are divided into superficial and deep dermoids. Depending on type and location, superficial ocular dermoid cysts are divided into limbal, dermoid cyst and epibulbar dermoid cyst or dermolipoma. The most common location for the epibulbar dermoid cyst is inferotemporal region of eye. They are usually asymptomatic or may present with inflammatory response due to leakage of cyst contents or may cause local irritation due to protruding hair and do cause cosmetic blemish to a school going child. For local irritation and cosmetic reasons, complete surgical excision with intact capsule of epibulbar dermoid cyst is mandatory to prevent acute inflammatory response and its recurrence. In this article we are presenting the clinical features and surgical management of an inferotemporal epibulbar dermoid in a male patient.

    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.

    There is no universally agreed policy for treating keloid scars of the ear lobe following piercing. We treated 35 patients (34 women) for high-risk ear-lobe keloids; the average age was 24 years (range: 16-44 years). All had failed to respond to prior treatment with massage and silicone, and corticosteroid injection. The keloids were excised extralesionally and the defects were closed with interrupted prolene sutures. The operative scar was covered with topical 2% lignocaine-0.25% chlorhexidine sterile lubricant gel under a transparent adhesive dressing. Adjuvant postoperative radiotherapy of 10 Gy, applied as 100 kV photons (4 mm high-voltage therapy (HVT) Al), was given within 24 h of surgery. All keloid scars were controlled at 4 weeks' follow-up. At 1 year, three out of 34 cases followed up had relapsed (probability of control: 91.2%). At 5 years, a further four out of the remaining 31 patients had relapsed (cumulative probability of control at 5 years: 79.4%). There were no cases of serious toxicity.

    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.

  17. Uracil excision repair in Mycobacterium tuberculosis cell-free extracts.

    2011-05-01

    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.

    2010-05-01

    Skin tumours of the anterior auricular concha are not uncommon. Wider excision and immediate reconstruction are required to reduce the risks of recurrence of the disease, cartilage infection and external ear distortion. Many surgical methods have been described for reconstruction of conchal defects. Post-auricular island flaps, such as the revolving-door (RD) flap, and full-thickness skin grafts (FTSGs) are the most-performed procedures. Although the RD flap has been fully described, it is not widely accepted and many surgeons, in their daily practice, prefer to use FTSG. It is a common experience that FTSGs are more subjected to centripetal contraction, decreasing the structural firmness of the conchal cavity and affecting functional and aesthetic outcomes. Furthermore, FTSGs are more prone to delay in wound healing due to the difficult access to this region that hinders adequate tie-over dressings. Between March 2003 and January 2007, 40 patients affected by T1 and T2 non-melanotic skin cancer and T1 melanoma of the anterior conchal surface of the external ear were included in a prospective study and randomly assigned to the RD reconstructed group or to the FTSG reconstructed group to investigate, compare and define advantages and disadvantages of both the techniques. Visual Analogue Scale (VAS) was used to evaluate the overall outcome and the colour and texture match. No flap or skin graft total loss was observed. Six patients (30%) showed partial failure of FTSG. The RD group demonstrated excellent cosmetic outcome, ideal colour match, adequate structure of external ear, projection and shape. Wilcoxon matched-pairs rank-sum test demonstrated statistically significant higher scores for the RD group compared to the FTSG group (p<0.0001). The RD harvesting technique is easy and quicker than the FTSG technique. RD flap should be considered as the first choice for reconstruction of anterior auricular conchal defects following wider excision of skin tumours

    Congenital choledochal cyst (CChC) has a very low frequency in our population; it is more frequent among females and its pattern of inheritance is multifactorial. The frequency of CChC in our population was 1 per 20,000 to 1 per 30,000 hospitalized patients in the pediatrics department of the Hospital Juarez and Hospital Infantil de Tacubaya, respectively. Four new cases of CChC are reported, two school children and two teenagers. Pre-operative diagnosis was accomplished clinically, which is the most precise non-invasive method. The most effective actual diagnostic methods include ultrasonography, CAT scan, and basic laboratory data, which can corroborate the clinical diagnosis of CChC with 100% certainty. The surgical treatment of CChC is controversial, but the surgical procedures of choice are choledochocystojejunostomy with total cyst removal, Roux's Y, and cholecystectomy. One case was treated with latero-terminal choledochocystojejunostomy and 3 cases with total removal of the cyst. The results were excellent.

    Skin cancers are the most common types of cancer and their incidence has shown an increase of ∼4 to 8% per year over the last 40 years. The majority of skin cancers (∼97%) are non-melanoma skin cancers, mainly represented by basal cell (80%) and squamous cell carcinomas (20%). The use of intra-operative frozen section remains controversial in the surgical treatment of non-melanoma skin cancer, being commonly considered an optional tool, the reliability and effectiveness of which remain questionable. A large retrospective study was conducted to examine 670 surgical excisions of non-melanoma skin cancers of the head and neck in 481 patients over a period of nine years, between May, 2002 and December, 2011, at the Plastic and Reconstructive Surgery Unit of the University of Pavia, Salvatore Maugeri Research and Care Institute, Pavia, Italy. Results demonstrated the paradoxical ineffectiveness of an intra-operative frozen section biopsy in pursuing higher rates of radical excision in non-melanoma skin cancers. Nevertheless, a more detailed analysis on the use of frozen sections focusing on the various anatomical sites of the body demonstrated a reverse trend in the eyelids and canthi, where a higher success rate (87.50 vs. 69.77%) in the surgical treatment of non-melanoma skin cancers was obtained with the use of an intra-operative frozen section biopsy. Results of the present study suggested that intra-operative frozen section biopsy be routinely used in the surgical treatment of nonmelanoma skin tumors involving the eyelids and canthi.

  1. Impact of cigarette taxation policy on excise revenues and cigarette consumption in Uzbekistan

    Full Text Available BACKGROUND: In 2012, Uzbekistan ratified the Framework Convention on Tobacco Control, which states that price and tax measures are an effective means of reducing tobacco consumption. We aimed to explore the effect of taxation policies on revenues and cigarette consumption. METHODS: Data on tax rates, revenues, cigarette sales were taken from national reports. To forecast potential revenues, a scenario analysis was performed. RESULTS: In 1991-2004, ad valorem excise system was in place in Uzbekistan, which was later replaced by the specific excise system. In 1997-2011, the nominal average excise has increased by a factor of twenty, but in real terms, after a sharp increase in 1999, average excise declined annually and increased only in 2010-2011. Annual cigarette sales per capita of adult population in 1999-2007 constituted 17-25 cigarette packs, while in 2008-2011 it increased to 30-37 packs. Four scenarios of excise tax increases in 2012 were developed: one actual scenario based on the rates effective in Uzbekistan in 2012, and three hypothetical ones anticipating excise rates increase by 1.5, 2 and 3-fold. With actual excise increase in 2012, the inflation-adjusted budget revenues would grow by 5%, and with three hypothetical - by 17%, 35% and 66% respectively, despite the decline of tax-paid cigarette sales. CONCLUSION: Stabilization or reduction in cigarette excises in Uzbekistan in 2002-2008 led to a decline in real excise revenues and the growth of cigarette sales. In 1999 and 2010-2011, excises were significantly increased and the real revenues have risen, despite the decline in cigarette sales. As cigarette prices are low, the illegal outflow of cigarettes from Uzbekistan apparently exceeds the illegal inflow. A significant increase in cigarette excise (1.5-3 fold can both increase budget revenues and reduce cigarette consumption, with greater increase yielding more benefits.

  2. Radical vs. Conservative Surgical Treatment of Hepatic Hydatid Cyst: A 10- Year Experience

    2009-07-01

    Full Text Available Introduction: Hepatic hydatid cyst is caused by echinococcosis granulosis. It is a major health problem in endemic areas. The modern treatment of hydatid cysts of the liver varies from surgical intervention to percutaneous drainage or medical therapy. A high rate of complications following percutaneous drainage, and ineffectiveness of medical therapy have shown not to be the definitive treatments for the disease. Thus, surgery is still the best choice for the treatment of hydatid cyst of the liver. Surgical treatment methods can be divided into radical and conservative approaches. There is controversy regarding efficacy of the two surgical methods. In this study, we aimed to present a retrospective evaluation of the two surgical methods in patients treated for the hepatic hydatid cyst. Methods: This retrospective study reviewed medical records of 135 patients who underwent surgery for hepatic hydatid cyst from 1997 to 2007. Surgery comprised conservative methods (evacuation of the cyst content and excision of the inner cyst layers and radical methods (total excision of the cyst and removal of its outer layer. Results: One hundred thirty five patients underwent liver surgery. Conservative surgery was performed for 71 (53%, whereas, the remaining 64 patients (47% underwent radical surgery. Postoperative complications were 28% and 19%, respectively. Recurrence of the cyst in the conservative and radical surgery groups was noted to be 12.5 and 1.5%, respectively. The mean length of hospital stay was shorter in the radical surgery group (5 vs. 15 days. Conclusion: Radical surgery may be the preferred treatment for the hepatic hydatid cyst because of its low rate of postoperative complications and recurrence, as well as short hospital stay. Selection of the most appropriate treatment depends on the size, number, and location of the cyst(s, and presence of cystobiliary communications, and the availability of an experienced surgeon.

    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

    The purpose of this prospective cohort study was to evaluate patient-based outcomes and complications following excision of mucous cysts, joint debridement, and closure with one of three types of local flaps. From 2000-2011, 35 consecutive patients with 37 digital mucous cysts were treated surgically. The surgical procedure included excision of the cyst together with the attenuated skin, joint debridement on the affected side including capsulectomy, and removal of osteophytes. Depending on the size and location of the cyst, the skin defect was covered by a transposition flap (31 cysts), an advancement flap (two cysts), or a rotation flap (four cysts). At an average follow-up time of 4 years, 4 months, there was no wound infection, flap necrosis, or joint stiffness. Preoperative nail ridging resolved in seven of nine fingers, and no nail deformities developed after surgery. One cyst, treated with a transposition flap, recurred 10 months after surgery. The average satisfaction score for the affected finger significantly improved from 4.3 to 6.8, and the average pain score decreased from 4.7 to 2.3. This treatment protocol provides reliable results. Patients were satisfied with the reduction of associated pain and the postoperative appearance of the treated finger, and postoperative complications were minimal.

    There is a wide variability in the management of acute cholecystitis. A survey among the members of the Spanish Association of Surgeons (AEC) analyzed the preferences of Spanish surgeons for its surgical management. The majority of the 771 responders didn't declare any subspecialty (41.6%), 21% were HPB surgeons, followed by colorectal and upper-GI specialities. Early cholecystectomy during the first admission is the preferred method of management of 92.3% of surgeons, but only 42.7% succeed in adopting this practice. The most frequent reasons for changing their preferred practice were: Patients not fit for surgery (43.6%) and lack of availability of emergency operating room (35.2%). A total of 88.9% perform surgery laparoscopically. The majority of AEC surgeons advise index admission cholecystectomy for acute cholecystitis, although only half of them succeed in its actual implementation. There is room for improvement in the management of acute cholecystitis in Spanish hospitals. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

    The purpose of this study was to assess the safety and the accuracy of surgical navigation technology in the resection of severe ankylosis of the mandibular condyle with the middle cranial fossa. The computed tomography scan data were transferred to a Windows-based computer workstation, and the patient's individual anatomy was assessed in multiplanar views at the workstation. In the operation, the patient and the virtual image were matched by individual registration with the reference points which were set on the skull bone surface and the teeth. Then, the real-time navigation can be performed. The acquisition of the data sets was uncomplicated, and image quality was sufficient to assess the operative result in 2 cases. Both of the operations were performed successfully with the guidance of real-time navigation. The application of surgical navigation has enhanced the safety and the accuracy of the surgery for bony ankylosis of temporomandibular joint. The use of surgical navigation resulted in the promotion of accurate and safe surgical excision of the ankylosed skull base tissue.

    Subungual melanoma (SUM) is a rare entity, comprising approximately 0·7-3·5% of all melanoma subtypes. SUM histopathologically belongs to the acral lentiginous pathological subtype of malignant melanoma. Its diagnosis is helped by dermoscopy but pathological examination of doubtful cases is required. Classical management of SUM is based on radical surgery, namely distal phalanx amputation. Conservative treatment with nonamputative wide excision of the nail unit followed by a skin graft has been insufficiently reported in the medical literature even though it is performed in many centres. To report a series of patients with in situ or minimally invasive SUM treated by conservative surgery, to investigate the postoperative evolution and to evaluate the outcome with a review of the literature. We performed a retrospective extraction study from our melanoma register of all patients with in situ and minimally invasive SUM treated with conservative surgery in the University Hospital Department of Dermatology, Lyon, France from 2004 to 2009. The patient demographics, disease presentation, delay to diagnosis, histopathology and postoperative evolution were reviewed. Seven cases of SUM treated as such were identified in our melanoma database. All cases had a clinical presentation of melanonychia striata. The mean delay to diagnosis was 2years. Surgical excision of the entire nail unit with a 5-10mm safety margin without bone resection followed by full-thickness skin graft taken from the arm was performed in all cases. No recurrence was observed with a mean follow-up of 45months. Functional results were found satisfactory by all patients and their referring physicians. Sixty-two other cases have been found in the literature and are also discussed. Conservative surgical management in patients with in situ or minimally invasive SUM is a procedure with good cosmetic and functional outcome and, in our cases as well as in the literature, the prognosis is not changed. © 2011

    Full Text Available Background: The effectiveness of care for patients with leukoplakia depends on how timely and accurately the disease was diagnosed and also by the subsequent choice of the optimal method of treatment. In recent decades, surgery is increasingly using methods that are alternative to standard surgical methods. Purpose: to justify, develop and evaluate treatment algorithm of verrucous and erosive-ulcerative forms of oral leukoplakia with a SIN2 histological structure. Materials and Methods: to achieve this goal, a comprehensive clinical and laboratory examination of 155 patients with oral leukoplakia was performed, which appealed to the Department of Therapeutic Dentistry of the  Bogomolets National Medical University in the period from 2011 to 2015. All patients underwent clinical and laboratory tests. Results: after removal of the affected area of the mucosa by radiation of an erbium laser, wound healing under fibrinous plaque was observed at 7.0 ± 0.5 days. When excision of the mucous membrane with a scalpel, the healing took place under the iodinine swab through the granulation phase for 14.0 ± 1.5 days. In patients after the operation of excision of the area of verrucous or erosive-ulcerative oral mucosa leukoplakia with laser radiation without antimicrobial and anti-inflammatory therapy on the third day, in 95% of cases there is no pain syndrome and collateral edema in the postoperative area. After traditional treatment, despite the use of antibiotics and non-steroidal anti-inflammatory drugs, 56% of patients complained of pain, and 62% had collateral edema. Conclusions: the use of ErrYAG laser laser radiation in the surgical treatment of patients with verrucous and erosive-ulcerative forms of leukoplakia promotes acceleration of healing processes of a postoperative wound twice as fast as in the control group. The use of laser technology reduces the risk of inflammatory purulent complications and helps to prevent the recurrence of the

    Full Text Available Objectives: Mycotic pseudoaneurysms of the extracranial internal carotid artery are rare, and their management often represents a challenge, but treatment is necessary due to the high risk of rupture and distal brain embolization. Systemic antibiotics associated with open surgical excision of the infected tissues and carotid reconstruction using autologous grafts are the treatment of choice. The use of endovascular techniques still remains controversial in infective fields; however, it can be an attractive alternative in high-risk patients or more often as a “temporary” solution to achieve immediate bleeding control for a safe surgical reconstruction. Methods: We discuss the unusual case of an extracranial right internal carotid artery mycotic pseudoaneurysm following methicillin-resistant Staphylococcus aureus infection, in a patient with poor general conditions. Results and Conclusion: The lesion was successfully treated using a hybrid endovascular and surgical procedure.

    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.

    Full Text Available Objective: The major factor for developing malignant skin cancers is sunlight exposure. This study aimed to evaluate the demographics of patients with skin cancers who underwent surgery in Diyarbakır where the population is exposed to more sunlight than most other Turkish cities. Methods: The medical records of patients who underwent surgery for malignant skin cancer excision between 2011 and 2016 were searched using University Hospital’s patient database program. Data about patients’ demographics, cancer features, and the surgical techniques performed were collected. Results: Over a 5-year period, 190 patients underwent surgical excision. The male to female ratio was 1.56, and the mean age was 65.8 ± 15.7 (range, 20-94 years. The most common skin cancer was basal cell carcinoma (n=138, 72.7%, followed by squamous cell carcinoma (n=45, 23.7% and malignant melanoma (n=5, 2.6%. The most common surgery was primary excision, which was performed in 90 of 190 patients (47.36%; tissue reconstruction with a skin graft or flap surgery was required for the remaining 100 (52.63%, showing a significant difference (p<0.001. Conclusion: Basal cell carcinoma is the most common skin cancer, and less than half of the patients sought treatment immediately after they recognized the lesion. The public should be educated about skin cancers to increase early diagnosis and encourage timely treatment, thereby decreasing morbidity and mortality from skin cancer.

  14. Mucosal tolerance disruption favors disease progression in an extraorbital lacrimal gland excision model of murine dry eye.

    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.

    Holbrook, Charlotte; Misra, Devesh

    2012-07-01

    Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? Urethral prolapse (UP) is a rare condition, with a suggested incidence of one in 3000. It occurs most often in prepubertal, primarily Black, girls. The underlying cause of this condition remains uncertain, although a lack of oestrogen is thought to have a role, owing to the preponderance of the condition in the prepubertal and postmenopausal age groups. A popular theory is that the problem arises as a consequence of poor attachments between the two layers of smooth muscle surrounding the urethra, combined with episodic increases in intraabdominal pressure. The most common presentation of UP is genital bleeding or a mass. The classical appearance of UP (i.e. the 'doughnut' sign) enables diagnosis to be made easily on clinical grounds alone. Optimum management of UP is less certain, with opinion divided on the merits of conservative therapy vs surgical excision. Conservative therapy aims to reduce mucosal oedema, improve local hygiene and counteract lack of oestrogen by using a combination of any or all of the following: Sitz baths, topical oestrogen cream, antibacterial wash/soap and topical antibiotics. Surgical management of UP involves excision of the prolapsed mucosa circumferentially. Several authors have reported success with surgical excision, but it carries a risk of developing stenosis of the urethral opening. The present study supports previously reported findings by other authors in terms of demographics and clinical presentation. Patient ages ranged from 2 to 15 years and all girls were of Black race. They most commonly presented with a mass (8/21 patients) or bleeding (6/21 patients) and diagnosis was confirmed on clinical examination, although one required a general anaesthetic (GA) to complete the examination. The present study shows that, in mild cases (usually where there is a mass without symptoms), UP can be successfully managed using

  19. Surgical treatment and management of the severely burn patient: Review and update.

    Science.gov (United States)

    Gacto-Sanchez, P

    Since one of the main challenges in treating acute burn injuries is preventing infection, early excising of the eschar and covering of the wound becomes critical. Non-viable tissue is removed by initial aggressive surgical debridement. Many surgical options for covering the wound bed have been described, although split-thickness skin grafts remain the standard for the rapid and permanent closure of full-thickness burns. Significant advances made in the past decades have greatly improved burns patient care, as such that major future improvements in survival rates seem to be more difficult. Research into stem cells, grafting, biomarkers, inflammation control, and rehabilitation will continue to improve individualized care and create new treatment options for these patients.

    In 2014, SSO-ASTRO published guidelines which recommended "no ink on tumor" as adequate margins for patients undergoing breast conservation for invasive breast cancer. In 2016, new SSO-ASTRO-ASCO guidelines recommended 2 mm margins for DCIS. We evaluated whether these guidelines affected re-excision rates at our institution. Patients treated with breast conservation surgery from January 1, 2010-March 1, 2016 were identified. Re-excision rates, tumor characteristics, and presence of residual disease were recorded. The 2016 guidelines were retrospectively applied to the same cohort and expected re-excision rates calculated. Re-excision rates did not significantly decline before and after 2014 guideline adoption (11.9% before, 10.9% after; p = 0.65) or when the 2016 guidelines were retrospectively applied (8.4%; p = 0.10). The 2014 and 2016 guidelines had minimal impact on our re-excision rates, as most re-excisions were done for DCIS and 2016 guidelines supported our prior institutional practices of 2 mm margins for these patients.

    Full Text Available Breast masses in children, though rare, present a difficult clinical challenge as they can represent a wide variety of entities from benign fibroadenomas to phyllodes tumors. Rapidly growing or recurrent masses can be particularly concerning to patients, families and physicians alike. Clinical examination and conventional imaging modalities are not efficacious in distinguishing between different tumor types and surgical excision is often recommended for both final diagnosis and for treatment of large or rapidly growing masses. While surgical excision can result in significant long-term deformity of the breast there are some surgical techniques that can be used to limit deformity and/or aid in future reconstruction. Here we present a case of recurrent giant juvenile fibroadenoma with a review of the clinical presentation, diagnostic tools and treatment options.

    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.

    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.

    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.

    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.

    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.

    Full Text Available Here we review our development of, and results with, high resolution studies on global genome nucleotide excision repair (GGNER in Saccharomyces cerevisiae. We have focused on how GGNER relates to histone acetylation for its functioning and we have identified the histone acetyl tranferase Gcn5 and acetylation at lysines 9/14 of histone H3 as a major factor in enabling efficient repair. We consider results employing primarily MFA2 as a model gene, but also those with URA3 located at subtelomeric sequences. In the latter case we also see a role for acetylation at histone H4. We then go on to outline the development of a high resolution genome-wide approach that enables one to examine correlations between histone modifications and the nucleotide excision repair (NER of UV-induced cyclobutane pyrimidine dimers throughout entire genomes. This is an approach that will enable rapid advances in understanding the complexities of how compacted chromatin in chromosomes is processed to access DNA damage and then returned to its pre-damaged status to maintain epigenetic codes.

    To determine the feasibility of using a mouse tumor model as a microsurgical training tool for otolaryngology-head and neck surgery (OHNS) trainees. Animal study. We injected athymic nude mice with human cutaneous squamous cell carcinoma (A431 cell line) deep to the parotid region overlying the masseter muscle. We sacrificed the animals 1 to 3 weeks postinjection, once a visible tumor growth was confirmed. We then asked 10 OHNS trainees to excise the tumor with preservation of the facial nerves under a high-magnification dissecting microscope. The trainees graded the tasks in several areas of specific measures using a visual analogue scale (VAS) including 1) tumor texture, 2) surgical realism, 3) usefulness, and 4) difficulty of the task. Noticeable tumor growth occurred within 5 days following A431 cell injection and reached measureable size (0.5-1.5 cm) within 1 to 3 weeks. The tumor displaced the facial nerve laterally and medially, with few demonstrating infiltration of the nerve. VAS scores (± standard deviation) were 8.1 (± 1.7), 7.7 (± 2.5), 9.0 (± 0.9) and 6.6 (± 1.9) for tumor texture, surgical realism, usefulness, and the difficulty of the task, respectively. We demonstrate a novel, reliable and cost-effective mouse model for simulating tumor extirpation microsurgery with preservation of important neural structures. OHNS trainees have found this simulation model to be realistic, useful, and appropriately challenging. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    Linegar, Daniel J; van Walbeek, Corne

    2018-01-01

    Introduction 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. Data 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. Methods 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. Findings 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. Conclusion 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.

    Carlos Ramon Silveira Mendes

    2015-07-01

    Full Text Available Introduction: Colorectal cancer is a serious public health problem. In 1982, Heald managed to reduce mortality by standardizing the total excision of mesorectum. The use of transanal endoscopic microsurgery has emerged to allow resection of rectal tumors as a minimally invasive method. With the association of Transanal Endoscopic Operation with total excision of mesorectum, it was possible to develop a new approach for total excision of mesorectum. Surgical technique: The procedure is started by the perineal time with Transanal Endoscopic Operation device; introduction of Transanal Endoscopic Operation system follows, with exposure of the lesion with a circumferential incision at a distance between 2 and 4 cm from distal tumor margin after making a purse string suture to close the rectal stump. Then, dissection is carried out by the posterior portion until reaching the presacral avascular fascia, completing the mesorectal circumferential dissection until the peritoneal reflection. After this step, a laparoscopic procedure is performed with the use of three trocars, with mobilization of splenic flexure and ligation of the inferior mesenteric artery, as well as confection of a protective ileostomy. Then, transanal removal of the surgical specimen is performed, and the procedure goes on with a coloanal anastomosis. Resumo: Introdução: O câncer colorretal é um serio problema de saúde publica. Em 1982, Heald conseguiu reduzir a mortalidade com a padronização da excisão total do mesoreto. O uso da Microcirurgia endoscópica transanal surgiu para proporcionar ressecções de tumores de reto como método minimamente invasivo. Com a associação do TEO a ETM foi possível desenvolver uma nova abordagem para ETM. Técnica cirúrgica: O procedimento é iniciado pelo tempo perineal com o aparelho de TEO. Em seguida o sistema TEO é introduzido, com exposição da lesão por meio de uma incisão circunferencial a cerca de 2 a 4 cm da margem distal

    Nodular hidradenocarcinoma was first reported as clear-cell eccrine carcinoma by Keasby and Hadley in 1954 (Cancer 1954;7:934-52) and rare malignant tumor. Several synonyms and related terms for nodular hidradenocarcinoma have appeared in the literature. They have potential for uncontrollable local recurrence, tend to metastasize, and often cause death. Most cases have been reported in the pathology literature with limited clinical information. We report a 27-year-old woman with nodular hidradenocarcinoma on the scalp. The management of rare cases is not well defined. In our case, she was only treated with a wide local excision, and no recurrence was observed 2 years after excision. Most authors have concluded that early wide surgical excision of the tumor is the treatment of choice. The efficiency of adjuvant therapy generally has not established.

    Because definitive long-term results are not yet available, the oncological safety of laparoscopic surgery for treatment of rectal cancer remains unproven. The aim of this prospective non-randomised study was to assess the feasibility and short-term outcome of laparoscopic total mesorectal excision (LTME) after 25--30 Gy preoperative radiotherapy and to compare the results with a matched-control group of open TME (OTME). A series of 41 patients with primary rectal cancer underwent LTME for rectal cancer and were matched with a historical control group of 41 patients who underwent OTME. Both groups received preoperative short-term radiotherapy. There was no mortality in the LTME group and 2% mortality in the OTME group. The overall postoperative morbidity was 37% in the LTME group and 51% in the OTME group, including an anastomotic leakage of 9 and 14% in the LTME and OTME groups respectively. A positive circumferential margin was found in 7% of patients in the LTME group and in 12% of the patients in the OTME group. This study shows that LTME is technically feasible and can be performed safely. We show at least a similar surgical completeness using a laparoscopic technique compared with open surgery.

    To expose our experience in the diagnostic and surgical treatment of neurogenic heterotopic ossification of the hip. We designed an observational retrospective descriptive study including 20 patients (30 hips) with neurogenic heterotopic ossification of the hip secondary to spinal cord injury attended in our institution in the last 10 years, with a minimum of one year follow-up. Medical files and imaging studies were reviewed. The study variables analyzed were: type and localization of neurogenic heterotopic ossification, pre-post excision range of motion, level and aetiology of spinal cord injury, ASIA score, smoking history, surgical approach and complications associated with surgery. A total of 20 patients were treated with resection of heterotopic ossification in 30 hips. 16 patients presented ASIA A spinal cord injury and 4 ASIA B spinal cord injury. Preoperatively all the patients had severe ankylosis in the hip that made sitting in a wheel chair and activities such as repositioning and hygiene difficult. The average postoperative motion at the follow-up evaluation was 90° in flexion, 20° of internal rotation and 40° of external rotation. Immediately after surgery all the patients followed a specific intensive physiotherapy regime for the hip and celecoxib 200 mg was administrated daily orally for a month to prevent recurrence of heterotopic bone formation. None of the patients reviewed suffered a recurrence of heterotopic bone formation. Surgical excision of hip ossification in order to achieve functional ROM of the hip is the best treatment for patients with neurogenic heterotopic ossification of the hip. Copyright © 2018 SECOT.

    Full Text Available Introduction: Pancreatic pseudocysts are frequent complications after acute and chronic pancreatitis. They are diagnosed in 6–18% of patients with the history of acute pancreatitis and in 20–40% cases with chronic pancreatitis. The aim of the study was to analyse early results of surgical treatment of pancreatic acute and chronic pseudocysts based on our experience. Material and methods: The retrospective analysis was based on early results of surgical treatment of 46 patients aged between 20 and 78 (33 males and 13 females who underwent treatment of acute (n = 26 and chronic (n = 20 pancreatic pseudocysts from November 2005 to July 2011 at the Second Department of General and Gastrointestinal Surgery and Surgical Oncology of the Alimentary Tract in Lublin. Results: The choice of a surgical method of treatment depended on the size, localisation, thickness of pseudocystic wall and changes in the main pancreatic duct. We used the following surgical methods: cystogastrostomy (Jurasz procedure was conducted in 22 patients (47.8%, Roux-en-Y cystojejunostomy was performed in 19 cases (41.3%, complete excision of the pseudocyst was possible in two patients (4.3% and cystoduodenostomy – in one case (2.1%. Also, in single cases external drainage (2.1% and cystopancreaticojejunostomy of Puestow (2.1% were applied. Forty-four patients (95.6% were cured. Early postoperative complications were observed in 2 patients (4.4%. Two reoperations (4.4% were required. Early postoperative mortality was 0%. Conclusions: Classic internal drainage procedures, known since the 19th century, are still effective methods of treatment in acute and chronic pancreatic pseudocysts.

    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).

    2018-03-25

    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.

    Full Text Available A 60-year-old male patient presented with complaints of persistent red to a brown-colored plaque on his scrotum, with duration of approximately three years. The patient had been treated with oral and topical antifungals for inguinal tinea for several months and after that with topical corticosteroids for eczema for several more months. None of the regimens achieved any therapeutic effect. The histopathological evaluation revealed the presence of atypical keratinocytes in all layers of the epidermis with the altered epidermal pattern, spread parabasal mitotic activity, without secondary satellites, multiple dyskeratotic cells and multinucleated cells. The diagnosis of an intraepithelial non-invasive squamous cell carcinoma, associated with koilocytic dysplasia and hyperplasia was made, meeting the criteria for Bowen disease. An elliptic surgical excision of the lesion was made, while the defect was closed with single stitches, with excellent therapeutic and aesthetic result. First described by John T. Bowen in 1912, Bowen disease (BD represents a squamous cell carcinoma (SCC in situ with the potential for significant lateral spread. Treatment options include the application of topical 5-flurorouracil cream – useful in non-hairy areas, imiquimod cream or destructive methods such as radiation, curettage, cryotherapy, laser ablation and photodynamic therapy, especially useful in nail bed involvement. Despite the early lesions, surgical excision is the preferred treatment option, regarding the potential malignant transformation risk.

    1965-01-01

    The cell population kinetics of excised, cultured pea roots was studied with the use of tritiated thymidine and colchicine to determine (1) the influence of excision, (2) the influence of sucrose concentration, (3) the average mitotic cycle duration, and (4) the duration of mitosis and the G 1, S, and G 2 periods of interphase.1 The results indicate that the process of excision causes a drop in the frequency of mitotic figures when performed either at the beginning of the culture period or after 100 hours in culture. This initial decrease in frequency of cell division is independent of sucrose concentration, but the subsequent rise in frequency of division, after 12 hours in culture, is dependent upon sucrose concentration. Two per cent sucrose maintains the shortest mitotic cycle duration. The use of colchicine indicated an average cycle duration of 20 hours, whereas the use of tritiated thymidine produced an average cycle duration of 17 hours. PMID:5857253

  6. Recombinant methods for screening human DNA excision repair proficiency

    International Nuclear Information System (INIS)

    Athas, W.F.

    1988-01-01

    A method for measuring DNA excision repair in response to ultraviolet radiation (UV)-induced DNA damage has been developed, validated, and field-tested in cultured human lymphocytes. The methodology is amenable to population-based screening and should facilitate future epidemiologic studies seeking to investigate associations between excision repair proficiency and cancer susceptibility. The impetus for such endeavors derives from the belief that the high incidence of skin cancer in the genetic disorder xeroderma pigmentosum (XP) primarily is a result of the reduced capacity of patients cells to repair UV-induced DNA damage. For assay, UV-irradiated non-replicating recombinant plasmid DNA harboring a chloramphenicol acetyltransferase (CAT) indicator gene is introduced into lymphocytes using DEAE-dextran short-term transfection conditions. Exposure to UV induces transcriptionally-inactivating DNA photoproducts in the plasmid DNA which inactivate CAT gene expression. Excision repair of the damaged CAT gene is monitored indirectly as a function of reactivated CAT enzyme activity following a 40 hour repair/expression incubation period

    2014-03-12

    We describe a case where full-thickness excision of a rectal lesion caused massive surgical emphysema and subsequent hypercarbia with associated difficulties with ventilation. This unique case highlights the risks of respiratory failure with extraperitoneal insufflation as in this case and as more commonly with intraperitoneal insufflation. Transanal endoscopic microsurgery (TEMS) is a technique that is being increasingly used in the management of large and early malignant rectal polyps. We reviewed the literature in order to understand the case and to highlight factors that should minimise any adverse sequelae. In the presence of ventilatory difficulties secondary to postoperative surgical emphysema, whether via extraperitoneal insufflation as described here or with intraperitoneal insufflation (as in laparoscopy), consider decreasing gas pressures, expediting the procedure, delaying extubation and prolonged close monitoring in recovery with possible admission to a high dependency unit (HDU) or intensive care unit (ICU).

    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.

    Although survival outcomes have been evaluated between those undergoing a planned primary excision and those undergoing a reexcision following an unplanned resection, the financial implications associated with a reexcision have yet to be elucidated. A query for financial data (professional, technical, indirect charges) for soft tissue sarcoma excisions from 2005 to 2008 was performed. A total of 304 patients (200 primary excisions and 104 reexcisions) were identified. Wilcoxon rank sum tests and χ2 or Fisher's exact tests were used to compare differences in demographics and tumor characteristics. Multivariable linear regression analyses were performed with bootstrapping techniques. The average professional charge for a primary excision was $9,694 and $12,896 for a reexcision (pfinancial burden nearly doubles.

    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

    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.

    We present a numerical code designed to study astrophysical phenomena involving dynamical spacetimes containing black holes in the presence of relativistic hydrodynamic matter. We present evolutions of the collapse of a fluid star from the onset of collapse to the settling of the resulting black hole to a final stationary state. In order to evolve stably after the black hole forms, we excise a region inside the hole before a singularity is encountered. This excision region is introduced after the appearance of an apparent horizon, but while a significant amount of matter remains outside the hole. We test our code by evolving accurately a vacuum Schwarzschild black hole, a relativistic Bondi accretion flow onto a black hole, Oppenheimer-Snyder dust collapse, and the collapse of nonrotating and rotating stars. These systems are tracked reliably for hundreds of M following excision, where M is the mass of the black hole. We perform these tests both in axisymmetry and in full 3+1 dimensions. We then apply our code to study the effect of the stellar spin parameter J/M 2 on the final outcome of gravitational collapse of rapidly rotating n=1 polytropes. We find that a black hole forms only if J/M 2 2 >1, the collapsing star forms a torus which fragments into nonaxisymmetric clumps, capable of generating appreciable 'splash' gravitational radiation

    Objective: To find out the optimal primary surgical treatment options for infected pseudoaneurysm in intravenous drug abusers. Study Design: Cross sectional descriptive study. Place and Duration of Study: Department of Vascular Surgery, Combined Military Hospital Lahore, from Jan 2010 to Jun 2015. Material and Methods: A total of 31 consecutive patients with a history of intravenous drug abuse and an infected pseudoaneurysm in the groin or elbow, presenting in emergency department; were included in this study. All patients were primarily treated with ligation of the artery, excision of infected pseudoaneurysm and debridement of necrotic tissues. Only one patient underwent additional revascularization procedure. Results: All patients who underwent ligation and excision procedures did well initially. One (3.2%) patient developed severe distal ischemia after ligation of femoral artery within first 24 hours, so extra anatomic revascularization procedure was performed. Five (16.1%) patients required revascularization procedure after 16 weeks due to disabling distal ischemia. No amputation was needed and mortality rate was zero. Conclusion: Primary ligation of the artery with excision of infected pseudoaneurysm and necrotic material was found the optimal initial management for infected pseudoaneurysm in intravenous drug addicts. Ischemic complications if develop should be treated with early or late revascularization.

    The excision of large retroperitoneal masses poses a challenge for every surgeon. Sometimes the urologist must face situations that do not fit to any conventional approach or technique previously described. Obtaining adequate exposure for safe and oncologically correct management of these masses is based, on many cases, in the mobilization of anatomical adjacent structures to generate a sufficient field in abdominal areas of difficult access. Complex visceral mobilization maneuvers derived from multivisceral transplantation organ procurement surgery provides ancillary techniques that used properly facilitate their successful resolution. The main purpose of this paper is the description of these surgical maneuvers essential to increase both exposure and vascular control in addressing the ever-dreaded high-volume retroperitoneal masses.

    Lonicera japonica Thunb. (Caprifoliaceae), a widely used traditional Chinese medicinal plant, is used to treat some infectious diseases and it may have uses as a healthy food and applications in cosmetics and as an ornamental groundcover. The ethanol extract of the flowering aerial parts of L. japonica (LJEE) was investigated for its healing efficiency in a rat excision wound model. Excision wounds were inflicted upon three groups of eight rats each. Healing was assessed by the rate of wound contraction in skin wound sites in rats treated with simple ointment base, 10% (w/w) LJEE ointment, or the reference standard drug, 0.2% (w/w) nitrofurazone ointment. The effects of LJEE on the contents of hydroxyproline and hexosamine during healing were estimated. The antimicrobial activity of LJEE against microorganisms was also assessed. The in vivo anti-inflammatory activity of LJEE was investigated to understand the mechanism of wound healing. LJEE exhibited significant antimicrobial activity against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Candida albicans, and Candida tropicalis. The ointment formulation prepared with 10% (w/w) LJEE exhibited potent wound healing capacity as evidenced by the wound contraction in the excision wound model. The contents of hydroxyproline and hexosamine also correlated with the observed healing pattern. These findings were supported by the histopathological characteristics of healed wound sections, as greater tissue regeneration, more fibroblasts, and angiogenesis were observed in the 10% (w/w) LJEE ointment-treated group. The results also indicated that LJEE possesses potent anti-inflammatory activity, as it enhanced the production of anti-inflammatory cytokines that suppress proinflammatory cytokine production. The results suggest that the antimicrobial and anti-inflammatory activities of LJEE act synergistically to accelerate wound repair.

    Full Text Available Background. Sweat gland carcinoma is a rare malignancy with a high metastatic potential seen more commonly in elderly patients. The scalp is the most common site of occurrence and it usually spreads to regional lymph nodes. Liver, lungs, and bones are the most common sites of distant metastasis. Late lung metastasis of sweat gland adenocarcinoma after a time span of 5 years is extremely rare. Aim. We report a patient with late lung metastasis of a primary sweat gland carcinoma 10 years after initial surgical resection. Conclusion. Sweat gland carcinomas are rare cancers with a poor prognosis. Surgery in the form of wide local excision and lymph node dissection is the mainstay of treatment. Late pulmonary metastases with a latency of 10 years have never been reported in the literature. This is the first clinical documentation of late lung metastasis from sweat gland carcinoma with a latency period of 10 years.

    Since the first use of robotic surgical system in 2000, the robot-assisted technology has gained wide popularity throughout the world. Robot-assisted surgical training is a complex issue that requires significant efforts from students and teacher. During the last two decades, simulation-based training had received active development due to wide-spread occurrence and popularization of laparoscopic and robot-assisted surgical techniques. We performed a systematic review to identify the currently available simulators for robot-assisted surgery. We searched the Medline and Pubmed, English sources of literature data, using the following key words and phrases: "robotics", "robotic surgery", "computer assisted surgery", "simulation", "computer simulation", "virtual reality", "surgical training", and "surgical education". There were identified 565 publications, which meet the key words and phrases; 19 publications were selected for the final analysis. It was established that simulation-based training is the most promising teaching tool that can be used in the training of the next generation robotic surgeons. Today the use of simulators to train surgeons is validated. Price of devices is an obvious barrier for inclusion in the program for training of robotic surgeons, but the lack of this tool will result in a sharp increase in the duration of specialists training.

    1997-01-01

    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

    Cells from a xeroderma pigmentosum patient XP2B1 who has reached 17 years of age with no keratoses or skin tumours constitute a new, 7th complementation group G. These cells exhibit a low residual level of excision repair, 2% of normal after a UV dose of 5 J/m 2 and an impairment of post-replication repair characteristic of excision-defective XPs. They are also sensitive to the lethal effects of UV and defective in host-cell reactivation of UV-irradiated SV40 DNA. (Auth.)

  1. Specifically requesting surgical tattoo removal: are deep personal motivations involved?

    Koljonen, V; Kluger, N

    2012-06-01

      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.

    To investigate the safety, feasibility and long-term outcomes of laparoscopic complete mesocolic excision for the transverse colon cancer. Clinical data of 61 patients who underwent laparoscopic complete mesocolic excision for transverse colon cancer (transverse group) in our department from January 2011 to January 2014 were retrospectively analyzed, which were compared with those of 155 patients undergoing laparoscopic complete mesocolic excision for ascending colon cancer (ascending group) and 230 patients undergoing laparoscopic complete mesocolic excision for sigmoid colon cancer (sigmoid group). Differences in operative details, postoperative recovery, postoperative complications and long-term survival among 3 groups were evaluated. No significant differences in the baseline information were found among 3 groups(all P>0.05). The average operative time was significantly longer in transverse group as compared to ascending group and sigmoid group [(192.1±58.7) min vs. (172.2±54.7) min and (169.1±53.6) min]( P0.05). A total of 436 patients received postoperative follow-up of median 36 (5 to 67) months. The overall 5-year survival rate was 73.1%, 73.7% and 74.8%, and the 5-year disease-free survival rate was 71.5%, 71.1% and 72.7% in transverse, ascending and sigmoid colon cancer groups respectively, whose differences were not significant among 3 groups (all P>0.05). Laparoscopic complete mesocolic excision for transverse colon cancer is safe and feasible with slightly longer operation time, and has quite good long-term oncologic efficacy.

    Complexity and operative risks of complete mesocolic excision (CME) seem to be important drawbacks to generalize this procedure in the surgical treatment of right colon cancer. Robotic systems have been developed to improve quality and outcomes of minimal invasive surgery. The aim of this study was to evaluate the feasibility of robotic right-sided CME and present our initial experience. A retrospective review of 37 patients undergoing totally robotic right-sided CME between February 2015 and November 2017 was performed. All the operations were carried out using the key principles of both CME with intracorporeal anastomosis and no-touch technique. Data on perioperative clinical findings and short-term outcomes were analyzed. There were 20 men and 17 women with a mean age of 64.4 ± 13.5 years and a body mass index of 26.8 ± 5.7 kg/m 2 . The mean operative time and estimated blood loss were 289.8 ± 85.3 min and 77.4 ± 70.5 ml, respectively. Conversion to laparoscopy occurred in one patient (2.7%). All the surgical margins were clear and the mesocolic plane surgery was achieved in 27 (72.9%) of the cases. The mean number of harvested lymph nodes was 41.8 ± 11.9 (median, 40; range 22-65). The mean length of hospital stay was 6.6 ± 3.7 days. The intraoperative and postoperative complication rates were 5.4 and 21.6%, respectively. We believe that use of robot for right-sided CME is feasible and appears to provide remarkably a high number of harvested lymph nodes with good specimen quality.

    2013-01-01

    Aim: To ascertain the negative predictive value (NPV) for atypia and malignancy of 14 G core biopsy of papillomas and to determine whether lesion type influences the likelihood of malignancy at lesion excision. Materials and methods: Ninety-six lesions with a 14 G core biopsy diagnosis of benign papilloma without atypia in 95 women were included. The imaging features (mass or microcalcification), biopsy mode, and number of core samples taken were documented. All patients subsequently underwent lesion excision with either extensive vacuum-assisted biopsy (VAB; 72 lesions) or surgery (24 lesions). Mammographic follow-up of at least 2 years was available for 32 lesions that were benign at VAB. Results: Atypia or malignancy was found more commonly in association with microcalcification (six of 29 lesions: 21%; median number of nine 14 G cores) than a mass (five of 67 lesions: 7%; median number of three 14 G cores), although the difference does not reach statistical significance (p = 0.088). The NPV of a 14 G core biopsy diagnosis of papilloma for atypia or malignancy is 89% (85/96). Disease underestimation may be more common in microcalcification lesions despite the greater number of cores obtained. Conclusion: Excision (using VAB or surgically) of all papillomas diagnosed as benign on 14 G needle core biopsy is recommended. Surgery may be more appropriate than VAB for some microcalcification lesions unless they are small and can be confidently removed in their entirety using VAB

    In a three-year prospective study, computed tomographic (CT) and surgical findings were compared for nine large breed dogs with lumbosacral stenosis. Surgically-excised tissue was examined histologically in seven dogs and additional necropsy evaluation was performed in one dog. The CT abnormalities observed at sites of confirmed cauda equina compression were: loss of epidural fat, increased soft tissue opacity, bulging of the intervertebral disc margin, spondylosis, thecal sac displacement, narrowed intervertebral foramen, narrowed vertebral canal, thickened articular process, articular process subluxation, articular process osteophyte, and telescoped sacral lamina. The CT characteristics of lumbosacral degenerative disease and discospondylitis were similar to those described in humans. In three dogs, CT findings at the site of cauda equina compression were consistent with congenital or developmental spinal stenosis, but the method of surgical exposure precluded confirmation. Epidural fibrosis (eight dogs) and multi-level CT abnormalities (six dogs) were identified but the cause(s) and significance were unknown

    To evaluate wrist strength and kinematics after pisiform excision and preservation of its soft tissue confluence for pisotriquetral instability and arthritis. We evaluated 12 patients, (14 wrists) subjectively and objectively an average of 7.5 years after pisiform excision. Three additional patients were interviewed by phone. Subjective evaluation included inquiry about pain and satisfaction with the treatment. Objective testing included measuring wrist flexion and extension range of motion, grip strength, and static and dynamic flexion and ulnar deviation strengths of the operative hand compared with the nonsurgical normal hand. Four patients had concomitant ulnar nerve decompression at the wrist. All patients were satisfied with the outcome. Wrist flexion averaged 99% and wrist extension averaged 95% of the nonsurgical hand. Mean grip strength of the operative hand was 90% of the nonsurgical hand. Mean static flexion strength of the operative hand was 94% of the nonsurgical hand, whereas mean dynamic flexion strength was 113%. Mean static ulnar deviation strength of the operative hand was 87% of the nonsurgical hand. The mean dynamic ulnar deviation strength of the operative hand was 103% of the nonsurgical hand. Soft tissue confluence-preserving pisiform excision relieved pain and retained wrist motion and static and dynamic strength. Associated ulnar nerve compression was a confounding factor that may have affected outcomes. Therapeutic IV. Copyright © 2014 American Society for Surgery of the Hand. Published by Elsevier Inc.

    2015-04-01

    Parapharyngeal space tumors are rare head and neck neoplasms, and most are benign lesions. Complete excision of these tumors is difficult because of the complexity of the surrounding anatomic structures. The algorithm for excision of these tumors is typically based on the tumor's characteristics; excision is performed via approaches such as the trans-oral route, the trans-cervical route, and even a combination of the trans-parotid route and mandibulotomy. However, each of these approaches is associated with some complications. Endoscope-assisted minimally invasive surgery is being increasingly employed for surgeries in the head and neck regions. It has the advantage of leaving no facial scars, and ensures better patient comfort after the operation. Here, we report the use of endoscope-assisted trans-oral surgery for excision of parapharyngeal space tumors. The technique yields an excellent outcome and should be a feasible, safe, and economic method for these patients. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  11. Incomplete excision repair process after UV-irradiation in MUT-mutants of Proteus mirabillis

    International Nuclear Information System (INIS)

    Stoerl, K.

    1977-01-01

    MUT-mutants of P. mirabilis seem to be able to perform the incision step in the course of excision repair. In contrast to the corresponding wildtype strains with MUT-mutants the number of single-strand breaks formed after UV-irradiation is independent of the UV-dose up to about 720 erg/mm 2 . Incubation in minimal medium over a longer time does not result in completion of excision repair; about 3-6 single-strand breaks in the DNA of these mutants remain open. Likewise, the low molecular weight of the newly synthesized daughter DNA confirms an incompletely proceeding or delayed repair process. As a possible reason for the mutator phenotype an alteration of the DNA-polymerase playing a role in excision and resynthesis steps of excision repair is discussed. (author)

    2017-01-01

    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.

    International Nuclear Information System (INIS)

    Richardson, J.L.

    1981-01-01

    The data presented examine the relationship between postlaryngectomy communication method, and the extent of total laryngectomy and the use of radiation therapy. The expectations of speech therapy providers were also examined. The author interviewed 60 laryngectomy patients who were six months to 3 1/2 years postsurgery. Surgeries were grouped into four categories and correlated with communication method. The relationship was statistically significant with the most apparent deterrent effect exhibited only for the most extreme surgical excisions.

    A wide spectrum of DNA lesions are repaired by the nucleotide-excision repair (NER) pathway in both eukaryotic and prokaryotic cells. We have developed a cell-free system in Saccharomyces cerevisiae that supports NER. NER was monitored by measuring repair synthesis in DNA treated with cisplatin or with UV radiation. Repair synthesis in vitro was defective in extracts of rad1, rad2, and rad10 mutant cells, all of which have mutations in genes whose products are known to be required for NER in vivo. Additionally, repair synthesis was complemented by mixing different mutant extracts, or by adding purified Rad1 or Rad10 protein to rad1 or rad10 mutant extracts, respectively. The latter observation demonstrates that the Rad1 and Rad10 proteins directly participate in the biochemical pathway of NER. NER supported by nuclear extracts requires ATP and Mg 2+ and is stimulated by polyethylene glycol and by small amounts of whole cell extract containing overexpressed Rad2 protein. The nuclear extracts also contain base-excision repair activity that is present at wild-type levels in rad mutant extracts. This cell-free system is expected to facilitate studies on the biochemical pathway of NER in S. cerevisiae

  17. Scar endometrioma following obstetric surgical incisions: retrospective study on 33 cases and review of the literature

    Directory of Open Access Journals (Sweden)

    Guilherme Karam Corrêa Leite

    Full Text Available CONTEXT AND OBJECTIVE: The incidence of scar endometrioma ranges from 0.03 to 3.5%. Certain factors relating to knowledge of the clinical history of the disease make correct diagnosis and treatment difficult. The aim here was to identify the clinical pattern of the disease and show surgical results. The literature on this topic was reviewed. DESIGN AND SETTING: Retrospective descriptive study at Hospital Municipal Maternidade - Escola Dr. Mário de Moraes Altenfelder Silva. METHODS: Data from the medical records of patients with preoperative diagnoses of scar endometrioma who underwent operations between 2001 and 2007 were surveyed and reviewed. The postoperative diagnosis came from histopathological analysis. The main information surveyed was age, obstetric antecedents, symptoms, tumor location, size and palpation, duration of complaint, diagnosis and treatment. All patients underwent tumor excision with a safety margin. RESULTS: There were 33 patients, of mean age 30.1 ± 5.0 years (range: 18-41 years. The total incidence was 0.11%: 0.29% in cesarean sections and 0.01% in vaginal deliveries. Twenty-nine tumors (87.9% were located in cesarean scars, two (6.0% in episiotomy scars and two (6.0% in the umbilical region. The main symptom was localized cyclical pain (66.7%, of mean duration 30.5 months (± 23. Surgical treatment was successful in all cases. CONCLUSION: This is an uncommon disease. The most important diagnostic characteristic is coincidence of painful symptoms with menstruation. Patients undergoing cesarean section are at greatest risk: relative risk of 27.37 (P < 0.01. The surgical treatment of choice is excision of the endometrioma with a safety margin.

    Lack of reliable assays for DNA repair has largely prevented measurements of DNA repair from being included in human biomonitoring studies. Using newly developed modifications of the comet assay we tested whether a fruit- and antioxidant-rich plant-based intervention could affect base excision repair (BER) and nucleotide excision repair (NER) in a group of 102 male volunteers. BER and NER repair capacities were measured in lymphocytes before and after a dietary intervention lasting 8 weeks. The study had one control group, one group consuming three kiwifruits per day and one group consuming a variety of antioxidant-rich fruits and plant products in addition to their normal diet. DNA strand breaks were reduced following consumption of both kiwifruits (13%, p = 0.05) and antioxidant-rich plant products (20%, p = 0.02). Increased BER (55%, p = 0.01) and reduced NER (-39%, p plant products. Reduced NER was also observed in the kiwifruit group (-38%, p = 0.05), but BER was not affected in this group. Here we have demonstrated that DNA repair is affected by diet and that modified versions of the comet assay can be used to assess activity of different DNA repair pathways in human biomonitoring studies.

    2014-01-01

    Central polydactyly is the least common form of foot polydactyly, and the intercalary location of the duplicated ray makes the surgical exposure, excision, and closure more complex. For these reasons there is little consensus concerning the optimal technique for surgical management. A retrospective case series of 22 patients with 27 feet with central polydactyly, treated surgically by the dorsal and plantar advancement flap technique, was performed. Change in width of the forefoot was measured from radiographs by the metatarsal gap ratio. Functional outcomes were assessed by the Foot and Ankle Ability Measure. Signficant narrowing of the forefoot, as measured radiographically by the metatarsal gap ratio, was achieved after surgery (Psports, and overall function categories. The few reports of less than normal foot function were related to shoe wear issues and incisional scarring that was painful or cosmetically unappealing. The radiographic and functional outcomes after surgical management of central polydactyly with the dorsal and plantar advancement flap technique are excellent. The technique successfully narrows the forefoot on radiographs, and this narrowing is maintained with growth over time. However, families should be advised that persistent perceived widening of the forefoot relative to normal is common, despite successful radiographic narrowing after surgery. IV.

    Cancer is caused by the loss of controlled cell growth due to mutational (in)activation of critical genes known to be involved in cell cycle regulation. Three main mechanisms are known to be involved in the prevention of cells from becoming cancerous; DNA repair and cell cycle control, important to remove DNA damage before it will be fixed into mutations and apoptosis, resulting in the elimination of cells containing severe DNA damage. Several human syndromes are known to have (partially) deficiencies in these pathways, and are therefore highly cancer prone. Examples are xeroderma pigmentosum (XP) caused by an inborn defect in the nucleotide excision repair (NER) pathway and the Li-Fraumeni syndrome, which is the result of a germ line mutation in the p53 gene. XP patients develop skin cancer on sun exposed areas at a relatively early age, whereas Li-Fraumeni patients spontaneously develop a wide variety of early onset tumors, including sarcomas, leukemia's and mammary gland carcinomas. Several mouse models have been generated to mimic these human syndromes, providing us information about the role of these particular gene defects in the tumorigenesis process. In this review, spontaneous phenotypes of mice deficient for nucleotide excision repair and/or the p53 gene will be described, together with their responses upon exposure to either chemical carcinogens or radiation. Furthermore, possible applications of these and newly generated mouse models for cancer will be given.

  3. Pathogenicity Island Cross Talk Mediated by Recombination Directionality Factors Facilitates Excision from the Chromosome.

    Science.gov (United States)

    Carpenter, Megan R; Rozovsky, Sharon; Boyd, E Fidelma

    2015-12-14

    Pathogenicity islands (PAIs) are mobile integrated genetic elements (MIGEs) that contain a diverse range of virulence factors and are essential in the evolution of pathogenic bacteria. PAIs are widespread among bacteria and integrate into the host genome, commonly at a tRNA locus, via integrase-mediated site-specific recombination. The excision of PAIs is the first step in the horizontal transfer of these elements and is not well understood. In this study, we examined the role of recombination directionality factors (RDFs) and their relationship with integrases in the excision of two PAIs essential for Vibrio cholerae host colonization: Vibrio pathogenicity island 1 (VPI-1) and VPI-2. VPI-1 does not contain an RDF, which allowed us to answer the question of whether RDFs are an absolute requirement for excision. We found that an RDF was required for efficient excision of VPI-2 but not VPI-1 and that RDFs can induce excision of both islands. Expression data revealed that the RDFs act as transcriptional repressors to both VPI-1- and VPI-2-encoded integrases. We demonstrated that the RDFs Vibrio excision factor A (VefA) and VefB bind at the attachment sites (overlapping the int promoter region) of VPI-1 and VPI-2, thus supporting this mode of integrase repression. In addition, V. cholerae RDFs are promiscuous due to their dual functions of promoting excision of both VPI-1 and VPI-2 and acting as negative transcriptional regulators of the integrases. This is the first demonstration of cross talk between PAIs mediated via RDFs which reveals the complex interactions that occur between separately acquired MIGEs. Deciphering the mechanisms of pathogenicity island excision is necessary for understanding the evolution and spread of these elements to their nonpathogenic counterparts. Such mechanistic insight would assist in predicting the mobility of uncharacterized genetic elements. This study identified extensive RDF-mediated cross talk between two nonhomologous VPIs and

  5. Cigarette Excise Taxes in Context: Cautionary Lessons from the U.S. Experience.

    Science.gov (United States)

    Campbell, Richard B; Balbach, Edith D

    2015-01-01

    Cigarette excise taxes are an important tool in the World Health Organization Framework Convention on Tobacco Control strategy for reducing global tobacco consumption. However, contemporary tobacco control efforts also coincide with the proliferation of neoliberal economic programs calling for the withdrawal of state activity from the economy to facilitate trade. In this environment, cigarette excise taxes may be seen less as an instrument of tobacco control than a feature of an economic program that is punitive to lower-income people. This article reviews collaboration between progressive organizations in the United States and the tobacco industry in the 1980s and 1990s, documenting potential sources of unanticipated resistance to excise taxes and highlighting the tobacco industry's capacity to engage in policy issues through third-party surrogates. It is important for those implementing cigarette excise tax increases to distance tobacco control objectives from larger economic policy measures and for tobacco control advocates to build alliances with organizations working for economic fairness in order to address mutual concerns. © SAGE Publications 2015.

    Evaluation of surgical skills and competency are important aspects of the medical education process. Measurable and reproducible methods of assessment with objective feedback are essential components of surgical training. Objective Structured Assessment of Technical Skills (OSATS) is widely used across the medical specialties and otolaryngology-specific tools have been developed and validated for sinus and mastoid surgery. Although assessment of surgical skills can be time-consuming and requires human and financial resources, new evaluation methods and emerging technology may alleviate these barriers while also improving data collection practices.

    2017-03-01

    The aim of this study was to review the experience of surgical treatment of low-grade chondrosarcoma and to assess the long-term oncological and functional outcomes between intralesional curettage and wide excision. We included 11 patients with central low-grade chondrosarcoma lesions treated with intralesional curettage or wide excision from 1998 to 2013. Seven patients were treated with intralesional curettage and local adjuvant treatment (Group A), and four patients were treated with wide excision and reconstructive surgery (Group B). The mean age of patients was 43.8±17.6 years (range, 20-71 years), and the mean duration of follow-up was 84.4±47.6 months (range, 48-194 months). Group A had a significantly lower complication rate than Group B; three complications were documented in Group B (0% vs. 75%, p=0.024). The operative time (177.1 hours vs. 366.3 hours, p=0.010) and the hospital stay (6.6 days vs. 12.5 days, p=0.010) were significantly shorter in Group A. There was one local recurrence in Group A without statistical significance. Also, there were no differences between intralesional curettage and wide excision with respect to the blood loss. No metastasis disease occurred in either group during the follow-up period. The Musculoskeletal Tumor Society (MSTS) scores in Groups A and B were 99.0±2.5 and 94.2±4.2, respectively, with statistically significant difference (p=0.048). Extended intralesional curettage has the benefits of good MSTS score, shorter operative time, shorter hospital stay, and lower complication rate without increasing local recurrence in central low-grade chondrosarcoma. For central low-grade chondrosarcoma, we suggest extended curettage to decrease soft tissue damage and surgical risk. Copyright © 2016. Published by Elsevier Taiwan LLC.

    2010-03-16

    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. 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. 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.

  9. Union women, the tobacco industry, and excise taxes: a lesson in unintended consequences.

    Balbach, Edith D; Campbell, Richard B

    2009-08-01

    Between 1987 and 1997, the tobacco industry used the issue of cigarette excise tax increases to create a political partnership with the Coalition of Labor Union Women (CLUW), a group representing female trade unionists in the U.S. This paper documents how the industry created this relationship and the lessons tobacco-control advocates can learn from the industry's example, in order to mitigate possible unintended consequences of advocating excise tax increases. In 1998, under the terms of the Master Settlement Agreement, the tobacco industry began making documents produced in litigation available publicly. Currently, approximately 50 million pages are available online, including substantial documentation of the industry-CLUW relationship. For this study, a comprehensive search of these documents was conducted. The tobacco industry encouraged CLUW's opposition to excise tax increases by emphasizing the economic regressivity of these taxes, discussing excise taxes generically to deflect attention from cigarettes, and encouraging opposition to earmarking cigarette taxes to pay for specific programs. In addition, CLUW received at least $221,500 in financial support between 1987 and 1997 and in-kind support for its conferences, membership materials, and other services. Excise tax increases, if pursued without considering the impacts they may have on low-SES populations, may have unintended consequences. In this case, such proposals may have helped to create a relationship between CLUW and the tobacco industry. Because excise taxes are endorsed in the Framework Convention on Tobacco Control, tobacco-control advocates must understand how to build relationships with low-SES populations and mitigate potential alliances with the tobacco industry.

  10. Methods of reconstruction for bone defect after tumor excision: a review of alternatives.

    Nishida, Jun; Shimamura, Tadashi

    2008-08-01

    Bone defect is a common problem encountered in the treatment of musculoskeletal tumor surgery. Allograft is a commonly used technique to reconstruct a large osseous defect following tumor excision in the United States and some European countries, and relatively good results have been reported because of its biologic nature. However, with the use of an allograft, there are concerns of transmission of infectious diseases, immunological reactions, and social or religious refusal in some regions in the world. Under these circumstances, vascularized autogenous fibular or iliac bone grafts are commonly used techniques and bone lengthening techniques using external fixation have been reported recently. These procedures utilize viable bone. In addition to these procedures, some biological reconstructive techniques utilizing nonviable bone have been performed as surgical alternatives for allografts using treated recycling bone including irradiated or pasteurized resected bone graft and reconstruction using an autograft containing tumor treated by liquid nitrogen. Although each technique has its proper advantages and disadvantages, the clinical results are similar to the allograft, and numerous techniques are now available as reasonable alternatives for allografts.

    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)

  12. Region of Interest Selection Interface for Wide-Angle Arthroscope

    2015-01-01

    Full Text Available We have proposed a new interface for an wide-angle endoscope for solo surgery. The wide-angle arthroscopic view and magnified region of interest (ROI within the wide view were shown simultaneously. With a camera affixed to surgical instruments, the position of the ROI could be determined by manipulating the surgical instrument. Image features acquired by the A-KAZE approach were used to estimate the change of position of the surgical instrument by tracking the features every time the camera moved. We examined the accuracy of ROI selection using three different images, which were different-sized square arrays and tested phantom experiments. When the number of ROIs was twelve, the success rate was best, and the rate diminished as the size of ROIs decreased. The experimental results showed that the method of using a camera without additional sensors satisfied the appropriate accuracy required for ROI selection, and this interface was helpful in performing surgery with fewer assistants.

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

    Science.gov (United States)

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

    2013-11-01

    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.

  18. Successful surgical treatment of intractable hemifacial spasm: A case report and review of cerebellar hamartomas of the floor of the fourth ventricle

    Directory of Open Access Journals (Sweden)

    Joseph H. Miller

    2016-12-01

    Full Text Available Introduction: Hamartomas involving the floor of the fourth ventricle and cerebellum are rare, but can be associated with medically recalcitrant hemifacial spasm. These lesions present early in the neonatal or infantile period and respond well to surgical excision. Case Report: A 3-month-old white male presented with recurrent left hemifacial spasm, left eye deviation, and absent movement of the extremities. The patient was found to have a left eccentric lesion in the floor of the fourth ventricle and cerebellum. The patient showed no improvement with medical therapy by 6 months of age. He was taken to the operating room for suboccipital craniotomy and removal of the posterior arch of C1 followed by intralesional recording of epileptogenic activity and gross total resection of the lesion. After histologic analysis, the lesion was determined to be ectopic cerebral tissue consistent with a hamartoma. Postoperative MRI showed complete removal of the lesion, and the patient exhibited complete remission of his hemifacial spasm and associated symptoms. Conclusions: Hamartomas involving the floor of the fourth ventricle can present with hemifacial spasm and respond well to surgical excision. Keywords: Cerebellar, Seizure, Epilepsy, Hamartoma

  19. Correlation of needle core biopsy with excision histology in screen-detected B3 lesions: the Merrion Breast Screening Unit experience.

    LENUS (Irish Health Repository)

    Hayes, B D

    2012-02-01

    AIMS: Needle core biopsy (NCB) is a widely-used technique for non-operative evaluation of screen-detected breast lesions. Although most NCBs are B2 (benign) or B5 (malignant), some fall into the B3 category of "uncertain malignant potential". This study aims to categorise the lesions prompting a B3 NCB in the Merrion Breast Screening Unit, and establish the incidence of malignancy on subsequent excision biopsy. METHODS: Patients attending the Merrion Breast Screening Unit in Dublin between 2000 and 2008 who had a B3 NCB were identified. The NCB pathology reports were reviewed and the diagnosis correlated with excision histology; the latter was classified as benign, atypical or malignant. Lesion-specific positive predictive values (PPVs) for malignancy were derived. RESULTS: 141 patients with a B3 NCB were identified. The most frequent lesions on NCB were radial scar (RS; n = 57), atypical intraductal epithelial proliferation (AIDEP; n = 25) and papillary lesion (n = 24). The final diagnosis was malignant in 22 patients (16%), atypical in 40 (28%) and benign in 79 (56%). Two of the patients with a malignant diagnosis had invasive carcinoma. The lesion-specific PPVs were: lobular neoplasia 50%, AIDEP 32%, columnar cell lesion with atypia 12.5%, RS 12.3%, papillary lesion 8.3%, suspected phyllodes tumour 7.7%, and spindle cell lesion 0%. Atypia on RS NCB predicted an atypical or malignant excision diagnosis, but atypia on papillary lesion NCB did not. CONCLUSIONS: One-sixth of B3 NCBs in this series proved to be malignant on excision. The PPV for malignancy varied according to lesion type.

    Ye, Yingjiang; Shen, Zhanlong; Wang, Shan

    2014-11-01

    Abominoperineal resection (APR) is the main approach of lower rectal cancer treatment. Recently, it was found that conventional APR had higher incidence rate of positive circumferential resection margin(CRM) and intraoperative perforation (IOP), which was the crucial reason of local recurrence and worse prognosis. Extralevator abdominoperineal excision(ELAPE) procedure was proposed by European panels including surgeons, radiologist and pathologists, and considered to lower the positive rates of CRM and IOP. Definitive surgical planes and anatomic landmarks are the cores of this procedure, which are the prerequisite for the guarantee of safety and smoothness of surgery. To realize the anatomy of muscles, fascias, blood vessels and nervous of perineal region is the base of carrying out ELAPE procedure. In this paper, we introduce the key anatomy related to ELAPE procedure and summarize the principle of ELAPE procedure as "two planes and four landmarks", which will be beneficial to the popularization and application.

    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.

    Megarectum in association with anorectal malformation contributes to chronic constipation and fecal incontinence. Resection of megarectum in anorectal malformation improves bowel function, but neuropathy and poor sphincter quality may affect the outcome of fecal continence adversely. The aim of this study was to evaluate the benefits of resection of megarectum in anorectal malformation and to ascertain the impact of anal sphincter quality and neuropathy on the outcome. We studied 62 children with intractable fecal incontinence after repair of anorectal malformation between January 1991 and January 2005. All patients were investigated with anorectal manometry and anal endosonography under ketamine anesthesia. On endosonography, an intact or scarred internal anal sphincter (IAS) was classified as good and a fragmented or absent IAS as poor. On manometry, a resting anal sphincter pressure equal to or more than 30 mm Hg was classified as good and a lower pressure as poor. Functional assessment of fecal continence was done before and after excision of megarectum using a modified Wingfield scores. Sixteen children had excision of megarectum with median age of 9 years (range, 2-15 years) and postoperative follow-up of 5 years (range, 1-10 years). Seven had formation of antegrade continent enema stoma before excision of megarectum. Children were classified into three groups of anomalies: low (n = 6), intermediate (n = 4), and high (n = 6). All children were incontinent of feces. After excision of megarectum, of the 9 children with good IAS and no neuropathy, 7 became continent of feces. Of the remaining 7 children, 4 had poor IAS and 3 had neuropathy, 5 of whom required an antegrade continent enema stoma to be clean. Excision of megarectum in children who had previous repair of anorectal malformation results in fecal continence in the presence of a good IAS and absence of neuropathy. Patients with a poor IAS or neuropathy will often require artificial means of fecal

  5. Abscisic Acid accumulates at positive turgor potential in excised soybean seedling growing zones.

    Science.gov (United States)

    Creelman, R A; Mullet, J E

    1991-04-01

    Abscisic acid (ABA) accumulated in soybean (Glycine max [L.] Merr. cv Williams) hypocotyl elongating regions when seedlings were transferred to low water potential vermiculite (Psi = -0.3 megapascals) even though positive turgor is retained in this tissue. Accumulation of ABA in growing zones could occur from de novo biosynthesis within this tissue or transport from adjacent nongrowing zones. Both growing and nongrowing hypocotyl and root tissues accumulated significant levels of ABA when excised and dehydrated to reduce turgor. Surprisingly, excised growing zones (which experienced no water loss) also accumulated ABA when incubated in darkness for 4 hours at 100% relative humidity and 29 degrees C. Induction of ABA accumulation in the excised elongating region of the hypocotyl was not caused by disruption of root pressure or wounding. While excision of hypocotyl elongating regions induced ABA accumulation, no change in either extensin or p33 mRNA levels was observed. Accumulation of extensin or p33 mRNA required more severe wounding. This suggests that ABA is not involved in the response of these genes in wounded tissue and that wound signals are not causing ABA accumulation in excised tissue. Accumulation of ABA in excised elongating regions was correlated with growth inhibition and a decline in turgor to the yield threshold (Psi;(p) = 0.37 megapascals; R Matyssek, S Maruyama, JS Boyer [1988] Plant Physiol 86: 1163-1167). Inhibiting hypocotyl growth by transferring seedlings to lower temperatures or light did not cause ABA accumulation. We conclude that induction of ABA accumulation in growing zones is more sensitive to changes in turgor than the induction which occurs in mature tissues.

    Full Text Available Abstract Background Bacillus anthracis is considered to be a recently emerged clone within the Bacillus cereus sensu lato group. The B. anthracis genome sequence contains four putative lambdoid prophages. We undertook this study in order to understand whether the four prophages are unique to B. anthracis and whether they produce active phages. Results More than 300 geographically and temporally divergent isolates of B. anthracis and its near neighbors were screened by PCR for the presence of specific DNA sequences from each prophage region. Every isolate of B. anthracis screened by PCR was found to produce all four phage-specific amplicons whereas none of the non-B. anthracis isolates, produced more than one phage-specific amplicon. Excision of prophages could be detected by a PCR based assay for attP sites on extra-chromosomal phage circles and for attB sites on phage-excised chromosomes. SYBR-green real-time PCR assays indicated that prophage excision occurs at very low frequencies (2 × 10-5 - 8 × 10-8/cell. Induction with mitomycin C increased the frequency of excision of one of the prophages by approximately 250 fold. All four prophages appear to be defective since, mitomycin C induced culture did not release any viable phage particle or lyse the cells or reveal any phage particle under electron microscopic examination. Conclusion The retention of all four putative prophage regions across all tested strains of B. anthracis is further evidence of the very recent emergence of this lineage and the prophage regions may be useful for differentiating the B. anthracis chromosome from that of its neighbors. All four prophages can excise at low frequencies, but are apparently defective in phage production.

    2012-01-01

    Surgical therapy remains the gold standard treatment for Peyronie's Disease (PD). Surgical options include plication, grafting, and placement of inflatable penile prosthesis (IPP). Postoperative erectile dysfunction (ED) is a potential complication for PD surgery without IPP. We present our large series follow-up to evaluate preoperative risk factors for postoperative ED. The aim of this study is to evaluate preoperative risk factors for the development of ED following surgical correction of PD taking into account the degree of curvature, graft size, surgical approach, hypertension, hyperlipidemia, diabetes, smoking history, preoperative use of phosphodiesterase 5 inhibitors (PDE5), and preoperative duplex ultrasound findings including peak systolic and end diastolic velocities and resistive index. We identified 218 men undergoing either tunica albuginea plication (TAP) or partial plaque excision with pericardial grafting for PD following a previously published algorithm between November 1992 and April 2007. Preoperative and postoperative erectile function, curvature characteristics, presence of vascular risk factors, and duplex ultrasound findings were available on 109 patients. Our primary outcome measure is the development of ED after surgery for PD. Ten percent of TAP and 21% of plaque excision with grafting patients developed postoperative ED. Neither curve direction (P = 0.76), graft area (P = 0.78), surgical approach (P = 0.12), chronic hypertension (P = 0.51), hyperlipidemia (P = 0.87), diabetes (P = 0.69), nor smoking history (P = 0.99) were significant predictors of postoperative ED. No combination of risk factors was found to be predictive of postoperative ED. Preoperative use of PDE5 was not a significant predictor of postoperative ED (P = 0.33). Neither peak systolic, end diastolic, nor resistive index were significant predictors of ED (P = 0.28, 0.28, and 0.25, respectively). This long-term follow-up of a large published series suggests that neither

    Gynecomastia is a common disorder observed in male plastic surgery patients. Treatment options may include observation, surgical excision, or liposuction techniques. Congenital herniated nipple is a more rare condition, especially in male patients. We present the case of a 12-year-old boy with bilateral gynecomastia and herniated nipple-areolar complexes. A staged repair was undertaken in this patient with grade 2 gynecomastia. The first operation was ultrasonic liposuction bilaterally, yielding 200 mL of aspirate from the left and 400 mL on the right, to correct the gynecomastia. The second procedure, performed 6 months later, was a bilateral periareolar mastopexy to repair the herniated nipple-areolar complexes. The result of the first procedure was flattened and symmetrical breast tissue bilaterally, essentially a correction of the gynecomastia. The herniated nipples were still present, however. Bilateral periareolar mastopexies were then performed with resulting reduction of the herniations. There were no complications with either procedure, and a good cosmetic result was achieved. A staged surgical approach was successful in correcting both conditions with an excellent aesthetic result and the advantage of decreased risk for nipple complications.

  13. Palliative Interventional and Surgical Therapy for Unresectable Pancreatic Cancer

    2011-01-01

    Palliative treatment concepts are considered in patients with non-curatively resectable and/or metastasized pancreatic cancer. However, patients without metastases, but presented with marginally resectable or locally non-resectable tumors should not be treated by a palliative therapeutic approach. These patients should be enrolled in neoadjuvant radiochemotherapy trials because a potentially curative resection can be achieved in approximately one-third of them after finishing treatment and restaging. Within the scope of best possible palliative care, resection of the primary cancer together with excision of metastases represents a therapeutic option to be contemplated in selected cases. Comprehensive palliative therapy is based on treatment of bile duct or duodenal obstruction for certain locally unresectable or metastasized advanced pancreatic cancer. However, endoscopic or percutaneous stenting procedures and surgical bypass provide safe and highly effective therapeutic alternatives. In case of operative drainage of the biliary tract (biliodigestive anastomosis), the prophylactic creation of a gastro-intestinal bypass (double bypass) is recommended. The decision to perform a surgical versus an endoscopic procedure for palliation depends to a great extent on the tumor stage and the estimated prognosis, and should be determined by an interdisciplinary team for each patient individually

    Current local treatment of vulvar cancer is wide tumor excision and radical vulvectomy based on functional anatomy established from the adult and on the view of radial progressive tumor permeation. Standard surgery is associated with a considerable local failure rate and severe disturbance of the patients' body image. Vulvar field resection (VFR) is based on ontogenetic anatomy and on the concept of local tumor spread within permissive compartments. VFR combined with anatomical reconstruction (AR) is proposed as a new surgical approach to the treatment of vulvar cancer. A prospective trial was launched to test the compartment theory for vulvar cancer and to assess safety and effectiveness of the new therapy. In 54 consecutive patients 46 tumors were locally confined to the tissue compartment differentiated from the vulvar anlage. The 8 tumors having transgressed into adjacent tissue compartments of different embryonic origins exhibited signs of advanced malignant progression. 38 patients with vulvar cancer, stages T1-3 were treated with VFR and AR. The perioperative complication rate was low. At 19 (3-50) months follow-up no patient failed locally. 33 patients estimated their body image as undisturbed. Vulvar cancer permeates within ontogenetic tissue compartments and surgical treatment with VFR and AR appears to be safe and effective. Patients should benefit from the new approach as local tumor control is high and the preserved tissue can be successfully used for restoration of vulvar form and function. Confirmatory trials with more patients and longer follow-up are suggested. Copyright © 2010 Elsevier Inc. All rights reserved.

    Surgical procedures were performed on 25 patients suffering from late-phase intestinal tract disorders induced by irradiation. The primary diseases of these cases were almost exclusively gynecological in nature, such as cancer of the uterine cervix. Symptoms observed in these cases were overwhelming ileus followed by melena, fistulation and free perforation, as well as combination thereof. The most common portion involved was the recto-sigmoidal colon, followed by the ileo-cecum and ileum. As for the relationship of symptoms to the disordered portion, ileus was seen mainly in cases of disorders at the ileocecal portion; melena was observed exclusively in cases of disorders at the rectosigmoidal colon; fistulation was manifested mainly as recto-vaginal fistula or ileo-sigmoidal fistula; free perforation was observed at both the ileum and sigmoidal colon. Colostomy was the most frequent surgical method applied. Only 3 cases were able to undergo enterectomy. Other cases were subjected to enteroanastomosis or enterostomy. In most cases it was nearly in possible to excise the disordered portions. As for the effect of surgical procedures on symptoms, cases of melena or fistulation were all subjected to colostomy; the majority of these cases showed improvement in symptoms. Moreover, a high improvement ratio was obtained in cases of ileus which were subjected to enterectomy and enteroanastomosis. Cases of free perforation showed high improvement ratio irrespective of the surgical procedure given. As for postoperative complications, one case of free perforation at the ileum showed anastomotic leakage after partial resection. For cases suffering from late-phase intestinal tract disorders induced by irradiation, immediate resection of the disordered intestinal tract and anastomosis are ideal. However, conservative operations must be considered, based on the focal condition. (author).

    Treatment of arteriovenous malformations (AVM) located at the eloquent area has been a challenge. Awake brain mapping allows identification of a non-eloquent gyrus for intervention and can potentially facilitate resection with preservation of functions. An alternative treatment option is stereotactic radiosurgery (SRS). The objective of this study was to perform a qualitative comparison of the treatment outcome of awake AVM excision versus SRS. We conducted a 13-year retrospective review of AVM excision under awake craniotomy performed at Prince of Wales Hospital, Hong Kong, from 2003 to 2016. Patients' presentation, Spetzler-Martin (SM) grading, rate of obliteration and complication were reviewed and analyzed with the modified radiosurgery-based AVM score (RS score). Six patients had excision of AVM under awake mapping during this period of time. Two were SM Grade II and four were SM Grade III. Five located at the peri-rolandic region while one at the temporal language area. None had failed mapping. Five out of six achieved complete obliteration (83.3%). Qualitative comparative analysis had revealed better treatment outcome with awake AVM excision as compared to SRS with the obliteration rate of 100% versus 96% for RS score ≤1.00, 100% versus 78% for RS score 1.01-1.50, and 66% versus 50% for RS score >2.00 respectively. In conclusion, awake mapping and excision of AVMs at the eloquent area is feasible. Qualitative comparative analysis had revealed higher obliteration rate with awake AVM excision as compared to SRS.

    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.

    Most authors recommend excision of intraductal papillomas diagnosed on core needle biopsy. This leads to the question of whether or not excision is necessary for incidental intraductal papillomas on core needle biopsy as opposed to those corresponding to imaging findings. Using the pathology computerized data base we retrospectively identified 46 incidental intraductal papillomas diagnosed on core needle biopsy from 1/2000 to 12/2008. Clinical, radiologic, and pathologic information was gathered and correlated. All core needle biopsies were reviewed to confirm the diagnosis of incidental intraductal papillomas, and excision specimens reviewed when available. Of the 46 patients, follow-up information was available in only 38. The age of the patients ranged from 39 to 82 years (mean = 48 years). Most incidental intraductal papillomas were diagnosed by mammotome core needle biopsy (36 cases). A total of 33 cases were performed for calcifications with the following indications: clustered = 21, new = 4, pleomorphic = 3, increasing = 3, indeterminant = 2. The correlating diagnoses included the following: fibrocystic changes with calcium phosphate = 18 or calcium oxalate = 10, fibroadenoma with calcifications = 5. The three masses were: two cases of cystic papillary apocrine metaplasia (I Ultrasound and 1 MRI) and 1 fibroadenoma (Ultrasound). In all cases, the intraductal papillomas were ≤0.2 cm, were not associated with calcifications, and were incidental to them or the underlying mass. A total of 14 patients underwent excision, whereas the remaining 24 have remained radiologically stable for over 12 months. The excision specimen findings were: fibrocystic changes = 8 and intraductal papilloma = 6. With the exception of one case, all the intraductal papilloma remained incidental to imaging findings. In this solitary case, the calcifications were described as pleomorphic and corresponded to fibrocystic changes calcifications on core needle

    We developed a system to study the influence of altered gravity on carbohydrate metabolism in excised wheat leaves by means of clinorotation. The use of excised leaves in our clinostat studies offered a number of advantages over the use of whole plants, most important of which were minimization of exogenous mechanical stress and a greater amount of carbohydrate accumulation during the time of treatment. We found that horizontal clinorotation of excised wheat leaves resulted in significant reductions in the accumulation of fructose, sucrose, starch and fructan relative to control, vertically clinorotated leaves. Photosynthesis, dark respiration and the extractable activities of ADP glucose pyrophosphorylase (EC 2.7.7.27), sucrose phosphate synthase (EC 2.4.4.14), sucrose sucrose fructosyltransferase (EC 2.4.1.99), and fructan hydrolase (EC 3.2.1.80) were unchanged due to altered gravity treatment.

    To study the outcome of the management of left atrial myxoma. The diagnosis was made according to clinical presentation and echocardiographic examinations. Tumour excised under cardiopulmonary bypass using aortic and bicaval cannulation and moderate hypothermia. Variables noted were surgical approach, pathological findings and complications after surgery. Of the 12 cases, six were male and six female, with a mean age of 33.67+-6.05 years. Fatigue and fever were the most common general symptoms, and dyspnoea the most common cardiologic symptom. The pedunculated atrial tumours were excised by trans-septal approach; tumour size ranged between 1.5x1x0.7 cms to 9x8x6 cms and weight 3-140 gms. Histopathology confirmed the tumours as atrial myxomas. One patient died of cerebrovascular accident on the 3rd postoperative day. So far, there has been no recurrence of the tumours. Surgical treatment with wide excision of left atrial myxomas by trans-septal approach is a suitable approach with negligible chances of recurrence. (author)

  6. A child with xeroderma pigmentosum for excision of basal cell carcinoma

    Full Text Available Xeroderma pigmentosum (XP is characterized by hypersensitivity to sunlight, ocular involvement, and progressive neurological complications. These manifestations are due to a cellular hypersensitivity to ultraviolet radiation leading to a defect in repair of DNA by the process of nucleotide excision repair. Basal cell carcinoma which is rare in children can occur with XP. Though the XP induced changes are predominately dermatologic, pose several challenges in anaesthetic management. Hence, we are reporting a 9-year-old child with XP scheduled for excision of basal cell carcinoma under general anaesthesia.

    Subareolar abscesses beginning either in infected skin glands or in breast ducts have an extraordinary tendency to recur and to be resistant to treatment. About three-fourths of 64 patients observed had from one to many recurrences of abscess after either spontaneous or surgical drainage, and many even after wide excision of scar in an interval of quiescence. The most successful of a number of methods of treatment used was wide removal of scar and underlying chronic abscess cavity combined with removal of the ampulla and mouth of a connecting duct. In a substantial number, after either drainage or unsuccessful excision, the process gradually subsided over a period of months or years. Cancer has not been observed in any of the 64 patients.

    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.

  9. Abscisic Acid Accumulates at Positive Turgor Potential in Excised Soybean Seedling Growing Zones 1

    Creelman, Robert A.; Mullet, John E.

    1991-01-01

    Abscisic acid (ABA) accumulated in soybean (Glycine max [L.] Merr. cv Williams) hypocotyl elongating regions when seedlings were transferred to low water potential vermiculite (Ψ = −0.3 megapascals) even though positive turgor is retained in this tissue. Accumulation of ABA in growing zones could occur from de novo biosynthesis within this tissue or transport from adjacent nongrowing zones. Both growing and nongrowing hypocotyl and root tissues accumulated significant levels of ABA when excised and dehydrated to reduce turgor. Surprisingly, excised growing zones (which experienced no water loss) also accumulated ABA when incubated in darkness for 4 hours at 100% relative humidity and 29°C. Induction of ABA accumulation in the excised elongating region of the hypocotyl was not caused by disruption of root pressure or wounding. While excision of hypocotyl elongating regions induced ABA accumulation, no change in either extensin or p33 mRNA levels was observed. Accumulation of extensin or p33 mRNA required more severe wounding. This suggests that ABA is not involved in the response of these genes in wounded tissue and that wound signals are not causing ABA accumulation in excised tissue. Accumulation of ABA in excised elongating regions was correlated with growth inhibition and a decline in turgor to the yield threshold (Ψ;p = 0.37 megapascals; R Matyssek, S Maruyama, JS Boyer [1988] Plant Physiol 86: 1163-1167). Inhibiting hypocotyl growth by transferring seedlings to lower temperatures or light did not cause ABA accumulation. We conclude that induction of ABA accumulation in growing zones is more sensitive to changes in turgor than the induction which occurs in mature tissues. Images Figure 2 PMID:16668113

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

    International Nuclear Information System (INIS)

    Tachibana, A.; Yonei, S.

    1985-01-01

    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)

    2017-08-01

    Da Vinci surgical system is the most advanced minimally invasive surgical platform in the world, and this system has been widely used in cardiac surgery, urology surgery, gynecologic surgery and general surgery. Although the application of this system was relatively late in thyroid surgery, the number of thyroidectomy with Da Vinci surgical system is increasing quickly. Having reviewed recent studies and summarized clinical experience, compared with traditional open operation, the robotic thyroidectomy has the same surgical safety and effectiveness in selective patients with thyroid cancer. In this paper, several aspects on this novel operation were demonstrated, including surgical indications and contraindications, the approaches, surgical procedures and postoperative complications, in order to promote the rational application of Da Vinci surgical system in thyroidectomy.

    Parathyroid crisis, also known as a parathyroid storm, is a rare and serious complication of primary hyperparathyroidism. Four cases are reported here in which patients presented to hospital with general complaints due to hypercalcemia secondary to hyperparathyroidism. Blood test results upon admission showed high levels of serum calcium and parathyroid hormone, and medical treatment initiated to lower the calcium level was ineffective. After relevant investigations, each patient underwent surgical exploration of the parathyroid glands, followed by excision of a pathological parathyroid tumor. There was a prompt decrease in parathyroid hormone level immediately after surgery. Histology reports revealed that patients had parathyroid adenoma. All patients recovered after surgery, with serum calcium levels restored back to normal and with resolution of all symptoms of hypercalcemia. This report illustrates how often this disease is initially misdiagnosed, and how prompt appropriate surgical treatment provides the best outcome for the patient.

    thoracotomy versus tube thoracostomy and VATS versus tube thoracostomy. We pooled data for meta-analysis where appropriate. We performed a subgroup analysis for children along with a sensitivity analysis for studies that used fibrinolysis in non-surgical treatment arms.The comparison of open thoracotomy versus thoracostomy drainage included only one study in children, which reported no deaths in either treatment arm. However, the trial showed a statistically significant reduction in mean hospital stay of 5.90 days for those treated with primary thoracotomy. It also showed a statistically significant reduction in procedural complications for those treated with thoracotomy compared to thoracostomy drainage. We downgraded the quality of the evidence for length of hospital stay and procedural complications outcomes to moderate due to the small sample size.The comparison of VATS versus thoracostomy drainage included seven studies, which we pooled in a meta-analysis. There was no statistically significant difference in mortality or procedural complications between groups. This was true for both adults and children with or without fibrinolysis. However, mortality data were limited: one study reported one death in each treatment arm, and seven studies reported no deaths. There was a statistically significant reduction in mean length of hospital stay for those treated with VATS. The subgroup analysis showed the same result in adults, but there was insufficient evidence to estimate an effect for children. We could not perform a separate analysis for fibrinolysis for this outcome because all included studies used fibrinolysis in the non-surgical arms. We downgraded the quality of the evidence to low for mortality (due to wide confidence intervals and indirectness), and moderate for other outcomes in this comparison due to either high heterogeneity or wide confidence intervals. Our findings suggest there is no statistically significant difference in mortality between primary surgical and

    2016-01-01

    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...... to open surgery and probably suboptimal oncological quality. Transanal TME (TaTME) can potentially solve these problems. The aim of this study was to compare the short-term results after TaTME with those after LaTME. METHODS: A prospectively collected database of consecutive patients who underwent Ta......TME was maintained. Results were compared with those underwent LaTME in the preceding period. Patients who underwent low anterior resection or intersphincteric abdominoperineal excision (APE) were included. Primary end-points were radical resection and specimen quality. Secondary end-points were complications, rates...

    To evaluate the effectiveness of the nail-fold excision procedure in children. Prospectively collected data on patients less than 18 years of age who underwent a nail-fold excision for symptomatic ingrown toenail were analyzed. Patients were seen in 2 centers and data collected included demographics, site of ingrown toenail, complications (including recurrence), patient satisfaction, and duration of follow-up. Overall, 67 procedures were performed on 50 patients between June 2009 and July 2011 at the 2 institutions. The mean age was 14 years (range, 9-18 years) and 30 were male patients. No recurrences were seen after a follow-up for a median of 14 months (range 6-28 months). Patients were very satisfied with the cosmetic outcomes. Six minor complications occurred, including 3 patients with bleeding requiring dressing change, 2 with excessive granulation tissue, and 1 with nail growth abnormality. The nail-fold excision technique is highly effective in the pediatric population, with no recurrence, excellent cosmesis, and very high patient satisfaction. Copyright © 2013 Mosby, Inc.

    2008-08-01

    Previous research has raised questions regarding the necessity of the frontal cortex in autobiographical memory and the role that it plays in actively retrieving contextual information associated with personally relevant events. Autobiographical memory was studied in patients with unilateral excisions restricted to the frontal cortex or temporal lobe involving the amygdalo-hippocampal region and in normal controls using an event-sampling method. We examined accuracy of free recall, use of strategies during retrieval and memory for specific aspects of the autobiographical events, including temporal order. Patients with temporal lobe excisions were impaired in autobiographical recall. By contrast, patients with frontal cortical excisions exhibited normal autobiographical recall but were less likely to use temporal order spontaneously to organize event retrieval. Instruction to organize retrieval by temporal order failed to improve recall in temporal lobe patients and increased the incidence of plausible intrusion errors in left temporal patients. In contrast, patients with frontal cortical excisions now surpassed control subjects in recall of autobiographical events. Furthermore, the retrieval accuracy for the temporal order of diary events was not impaired in these patients. In a subsequent cued recall test, temporal lobe patients were impaired in their memory for the details of the diary events and their context. In conclusion, a basic impairment in autobiographical memory (including memory for temporal context) results from damage to the temporal lobe and not the frontal cortex. Patients with frontal excisions fail to use organizational strategies spontaneously to aid retrieval but can use these effectively if instructed to do so.

    Although minimally invasive surgery (MIS) affords several advantages compared to conventional open surgery, robotic MIS systems still have many limitations. One of the limitations is the non-uniform gripping force due to mechanical strings of the existing systems. To overcome this limitation, a surgical instrument with a pneumatic gripping system consisting of a compressor, catheter balloon, micro motor, and other parts is developed. This study aims to implement a surgical instrument with a pneumatic gripping system and pitching/yawing joints using micro motors and without mechanical strings based on the surgical-operation-by-wire (SOBW) concept. A 6-axis external arm for increasing degrees of freedom (DOFs) is integrated with the surgical instrument using LabVIEW® for laparoscopic procedures. The gripping force is measured over a wide range of pressures and compared with the simulated ideal step function. Furthermore, a kinematic analysis is conducted. To validate and evaluate the system's clinical applicability, a simple peg task experiment and workspace identification experiment are performed with five novice volunteers using the fundamentals of laparoscopic surgery (FLS) board kit. The master interface of the proposed system employs the hands-on-throttle-and-stick (HOTAS) controller used in aerospace engineering. To develop an improved HOTAS (iHOTAS) controller, 6-axis force/torque sensor was integrated in the special housing. The mean gripping force (after 1,000 repetitions) at a pressure of 0.3 MPa was measured to be 5.8 N. The reaction time was found to be 0.4 s, which is almost real-time. All novice volunteers could complete the simple peg task within a mean time of 176 s, and none of them exceeded the 300 s cut-off time. The system's workspace was calculated to be 11,157.0 cm3. The proposed pneumatic gripping system provides a force consistent with that of other robotic MIS systems. It provides near real-time control. It is more durable than the

    Axillary bromhidrosis has a strong negative effect on one's social life. A high success rate and few complications are criteria for a surgical treatment. The objective of this study was to evaluate a new surgical treatment modality for bromhidrosis: subcutaneous scissor with micropore. Twenty patients with bromhidrosis were treated. Patients were placed in a supine position with their treated arms abducted to 110°. After injection of 60 mL of tumescent solution into each axilla, one small incision was made at the middle axillary of the hair-bearing area. The whole hair-bearing skin was undermined at the level of the superficial fat to obtain adequate skin eversion. The flaps were everted to offer full exposure of the apocrine glands, and meticulous excision of each gland was performed. Both sides were punctured with scalpel. The micropore was used for drainage, and whose width was just 3 mm. Finally, the incisions were re-approximated, and bulky compressive dressings were applied to the area for 72 hours. Of the 40 axillae (20 patients), 34 (85.0%) showed excellent results, and six (15.0%) had good results. Malodor was significantly decreased. There were no serious complications. This technique can produce excellent results with a lower complication rate than most other surgical modalities and can be performed without costly equipment. © 2017 Wiley Periodicals, Inc.

    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 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.

    2001-01-01

    Maintenance of the correct genetic information is crucial for all living organisms because mutations are the primary cause of hereditary diseases, as well as cancer and may also be involved in aging. The importance of genomic integrity is underscored by the fact that 80 to 90% of all human cancers are ultimately due to DNA damage. Among the different repair mechanisms that have evolved to protect the genome, nucleotide excision repair (NER) is a universal pathway found in all organisms. NER removes a wide variety of bulky DNA adducts including the carcinogenic cyclobutane pyrimidine dimers induced by UV radiation, benzo(a)pyrene-guanine adducts caused by smoking and the guanine-cisplatin adducts induced by chemotherapy. The importance of this repair mechanism is reflected by three severe inherited diseases in humans, which are due to defects in NER: xeroderma pigmentosum, Cockayne's syndrome and trichothiodystrophy.

    1995-11-01

    The excised patch clamp configuration provides a unique technique for some types of single channel analyses, but maintenance of stable, long-lasting preparations may be confounded by rundown and/or rapid loss of seal. Studies were performed on the amiloride-sensitive Na+ channel, located on the apical surface of A6 cells, to determine whether the nystatin-induced open cell-attached patch could serve as an alternative configuration. Compared to excised inside-out patches, stable preparations were achieved more readily with the open cell-attached patch (9% vs. 56% of attempts). In both preparations, the current voltage (I-V) relation was linear, current amplitudes were equal at opposite equivalent clamped voltages, and Erev was zero in symmetrical Na+ solutions, indicating similar Na+ activities on the cytosolic and external surfaces of the patch. Moreover, there was no evidence that nystatin altered channel activity in the patch because slope conductance (3-4pS) and Erev (75 mV), when the bath was perfused with a high K:low Na solution (ENa = 80 mV), were nearly equal in both patch configurations. Our results therefore indicate that the nystatin-induced open cell-attached patch can serve as an alternative approach to the excised inside-out patch when experiments require modulation of univalent ions in the cytosol.

  8. Implication of Posttranslational Histone Modifications in Nucleotide Excision Repair

    2012-09-01

    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.

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

    2016-09-07

    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.

    Verneuil's disease, or hidradenitis suppurativa, is a chronic suppurative disease with a tendency to sinus formation, fibrosis, and sclerosis. It is a disease of the apocrine sweat glands and may arise from each of the localizations where apocrine glands are prominent: axilla, nipples, umbilicus, perineum, groin, and buttocks. Extensive hidradenitis suppurativa of the perineal/perianal and the gluteal regions constitute a serious social problem. In this study, we present our experience with stage III extensive hidradenitis suppurativa cases, including our treatment methods and patient outcomes. A retrospective review of the medical records from January 1990 to July 2003 of 15 patients was performed. Fifteen patients underwent treatment for extensive hidradenitis suppurativa in the gluteal, perineal/perianal, and inguinal areas with total surgical excision. All patients were men (100%) and their mean age was 42.5 (range, 23-66) years. The patients underwent a total number of 21 operations. In 11 patients wounds were left open for secondary healing, and the mean time for complete wound healing in this group was 12.2 (range, 9.5-22) weeks. Two patients underwent primary wound closure by the application of rotation flaps, and their complete healing times were observed to be approximately 2 weeks. Delayed skin grafting was used for the remaining two patients in whom the wounds had been left open after the initial operation. In this group, complete wound healing took a total of 8 weeks. Only one diverting colostomy was needed in a patient in the delayed skin-grafting group. Squamous cell carcinoma was diagnosed in the specimens of one patient treated with total excision followed by the application of a rotation flap. This patient had had complaints of gluteal discharge for approximately 30 years. The cancer recurred after 6 months in the perianal region and immediate abdominoperineal resection was performed. He died during the second postoperative month due to systemic

    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.)

    One of the major ionizing radiation products, 5,6-dihydroxydihydrothymine (thymine glycol), was measured in the DNA of Micrococcus radiodurans following exposure of cells to 6.8-MeV electrons or 254-nm ultraviolet light. Removal of 5,6-dihydroxydihydrothymine was measured in both an ionizing radiation-sensitive strain (262) and a highly radioresistant strain (the wild type W + ) of Micrococcus radiodurans. Within 30 min of incubation (33 0 C) following exposure to ultraviolet light (2400 J/m 2 ) approximately 60% of the thymine glycols were excised, whereas in the case of ionizing radiation (250 krad) only 35% were removed from the cellular DNA of the wild-type strain. In contrast less than 50% of the thymine glycols were excised from the sensitive strain. The amount of DNA degradation induced by radiation was less than 10% in both strains. The results suggest a possible correlation between reduced excision repair of base damage and increased radiation sensitivity

    Many low- and middle-income countries (LMICs) have a high prevalence of unmet surgical need. Provision of operations through surgical outreach missions, mostly led by foreign organizations, offers a way to address the problem. We sought to assess the cost-effectiveness of surgical outreach missions provided by a wholly local organization in Ghana to highlight the role local groups might play in reducing the unmet surgical need of their communities. We calculated the disability-adjusted life years (DALY) averted by surgical outreach mission activities of ApriDec Medical Outreach Group (AMOG), a Ghanaian non-governmental organization. The total cost of their activities was also calculated. Conclusions about cost-effectiveness were made according to World Health Organization (WHO)-suggested parameters. We analyzed 2008 patients who had been operated upon by AMOG since December 2011. Operations performed included hernia repairs (824 patients, 41%) and excision biopsy of soft tissue masses (364 patients, 18%). More specialized operations included thyroidectomy (103 patients, 5.1%), urological procedures (including prostatectomy) (71 patients, 3.5%), and plastic surgery (26 patients, 1.3%). Total cost of the outreach trips was $283,762, and 2079 DALY were averted; cost per DALY averted was 136.49 USD. The mission trips were "very cost-effective" per WHO parameters. There was a trend toward a lower cost per DALY averted with subsequent outreach trips organized by AMOG. Our findings suggest that providing surgical services through wholly local surgical mission trips to underserved LMIC communities might represent a cost-effective and viable option for countries seeking to reduce the growing unmet surgical needs of their populations.

    A study is presented on the excision repair of ultraviolet-irradiated PHIX 174 RFI DNA in vitro with UV-specific endonuclease from micrococcus luteus, DNA polymerase I from E. coli and DNA ligase from phage T 4 infected E. coli. Excision repair was measured by physico-chemical and by biological methods. It is shown that more than 90% of the pyrimidine dimers can be repaired in vitro and that the repaired molecules have regained full biological activity. Endonuclease III was not essential for excision repair in vitro and did not stimulate repair; from this it was concluded that UV-endo generates 3' OH endgroups. The usefulness of the methods with regard to the study of excision repair is discussed

    Preliminary data have shown encouraging results of a single intratumoral radiopharmaceutical injection that enables both sentinel node biopsy and probe-guided excision of the primary tumor in patients with nonpalpable breast cancer. The aim of the study was to evaluate this approach in a large group of patients. Lymphoscintigraphy was performed in 368 patients with nonpalpable breast cancer after intratumoral injection of (99m)Tc-nanocolloid (.2 mL, 123 MBq, 3.3 mCi) guided by ultrasound or stereotaxis. The sentinel node was pursued with the aid of vital blue dye (1.0 mL, intratumoral) and a gamma ray detection probe. In case of breast-conserving surgery, the probe was used to guide the excision. At least one sentinel node could be identified intraoperatively in 357 patients (97%), of whom 69 had involved nodes (19%). Age over 60 years was associated with less frequent nonaxillary lymphatic drainage and absence of internal mammary chain dissemination. Tumor-free margins were obtained in 262 (89%) of the 293 patients who underwent segmental excision. Re-excision of the primary tumor bed was performed in six patients (2%). During a median follow-up of 22 months, one breast recurrence and one axillary recurrence were observed. Lymphatic mapping and probe-guided tumor excision of nonpalpable breast cancer by intralesional administration of a single dose of (99m)Tc-nanocolloid and blue dye resulted in 97% identification of the sentinel node and in tumor-free margins in 89% of the patients who underwent breast-conserving surgery. Longer follow-up is needed to substantiate the accuracy and safety of this technique.

    For patients with a wide, complete, unilateral cleft lip and palate, pre-surgical maxillary orthodontic treatments have been used to reduce the alveolar gap before cheiloplasty. However, most of these treatments are complicated and laborious for patients and for medical professionals. Thus, we developed an original pre-surgical orthodontic device made with two separate acrylic resin plates connected with a spring-shaped β-titanium wire (β-TW). When the device was applied on the palate, each segment of the maxilla was automatically aligned for our target formation with the elastic force of β-titanium alloy. This study aimed to evaluate the efficacy of the new device and the size of the maxilla in comparison with the conventional Hotz procedures. A total of 47 patients with a wide unilateral cleft lip and palate were retrospectively evaluated; 33 patients were treated with our new device (β-TW plate group) and 14 were treated with a Hotz plate (HP group). We evaluated the alveolar gap reduction and the size of the maxilla between the two groups, obtaining intraoral maxillary impressions at birth, at 3 months and 1 year. The width of the alveolar gap in the β-TW plate group was significantly reduced compared with that in the HP group 1 month after the treatment (p pre-surgical orthodontic treatments.

    Abstract The aim of this study was to evaluate the pathologic responses and changes to surgical strategies following preoperative chemoradiotherapy (PCRT) in rectal cancer patients according to their clinical T stage (cT). The use of PCRT has recently been extended to less advanced disease. The authors enrolled 650 patients with cT2 to 4 mid and low rectal cancer who received both PCRT and surgical resection. The rate of total regression and the proportion of local excision were compared according to the cT category. The 3-year recurrence-free survival (RFS) rate was compared using the log-rank test according to patient cT category, pathologic stage, and type of surgical treatment. Patients with cT2 were older (P = 0.001), predominately female (P = 0.028), and had low-lying rectal cancer (P = 0.008). Pathologic total regression was achieved most frequently in cT2 patients (54% of cT2 versus 17.6% of cT3 versus 8.2% of cT4; P rectal cancer, optimal surgical treatment may be achieved with the tailored use of PCRT.

  18. Interference Excision in Spread Spectrum Communications Using Adaptive Positive Time-Frequency Analysis

    Directory of Open Access Journals (Sweden)

    Krishnan Sridhar

    2007-01-01

    Full Text Available This paper introduces a novel algorithm to excise single and multicomponent chirp-like interferences in direct sequence spread spectrum (DSSS communications. The excision algorithm consists of two stages: adaptive signal decomposition stage and directional element detection stage based on the Hough-Radon transform (HRT. Initially, the received spread spectrum signal is decomposed into its time-frequency (TF functions using an adaptive signal decomposition algorithm, and the resulting TF functions are mapped onto the TF plane. We then use a line detection algorithm based on the HRT that operates on the image of the TF plane and detects energy varying directional elements that satisfy a parametric constraint. Interference is modeled by reconstructing the corresponding TF functions detected by the HRT, and subtracted from the received signal. The proposed technique has two main advantages: (i it localizes the interferences on the TF plane with no cross-terms, thus facilitating simple filtering techniques based on thresholding of the TF functions, and is an efficient way to excise the interference; (ii it can be used for the detection of any directional interferences that can be parameterized. Simulation results with synthetic models have shown successful performance with linear and quadratic chirp interferences for single and multicomponent interference cases. The proposed method excises the interference even under very low SNR conditions of  dB, and the technique could be easily extended to any interferences that could be represented by a parametric equation in the TF plane.

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

    Huang, H.; Claycamp, H.G.

    1993-01-01

    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)

    Treatment of heterotopic ossification (HO) of the elbow is challenging and fraught with complications. Patients who sustain direct trauma to the elbow joint, the central nervous system, and thermal burns are at increased risk for development of HO. There is a paucity of studies and reports on patient's self-evaluation after the excision of the heterotopic ossification. This retrospective study assessed outcomes after excision of heterotopic ossification around the elbow in a cohort of ten patients operated from 2012 to 2015. The outcome assessment was done by the Mayo Elbow Performance index (MEPI) and the American Shoulder and Elbow Surgeons-Elbow score (ASES-E scores). The mean follow-up was 18.11 months after the operation. The Mayo Elbow Performance Score was excellent in two elbows, good in six and fair in two. The mean gain in flexion-extension arc after excision of HO was 80 degrees. All of the patients had residual flexion deformity postoperatively. Eight of the nine patients were able to do activities requiring flexion at final follow-up. Excision of HO around the elbow is associated with satisfactory patient-rated outcomes in spite of failure to regain full range of motion.

    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.

  3. Excise Tax Avoidance: The Case of State Cigarette Taxes

    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

    Spontaneous meningoencephaloceles of the lateral sphenoid sinus are rare entities, and their peculiar location represents a surgical challenge due to the importance of a wide exposure and skull base reconstruction. They are thought to arise from the congenital base defect of the lateral sphenoid or in some cases have been postulated to represent a rare manifestation of altered cerebrospinal fluid (CSF) dynamics. We report the first case in the literature of a Chiari malformation type I (CMI) and a lateral sphenoid encephalocele, revising the theoretic etiology and surgical technique of endoscopic repair. A 50-year-old woman with a surgical history of symptomatic CMI presented with episodes of spontaneous CSF rhinorrhea. Radiologic investigations revealed a left mesial temporal encephalocele herniating into the lateral recess of the sphenoid sinus and radiologic features of altered CSF dynamics, which may have played an etiologic role. An endoscopic transpterygoid excision of the encephalocele and multilayer skull base repair were performed. The association of spontaneous lateral sphenoid encephaloceles with CMI is distinctly unusual. Predisposing factors and disruption of CSF dynamics may play a major role in the development of these rare complications in patients with CMI. Because of their distinct location, transethmoid or transpterygoid endoscopic approaches represent an excellent surgical technique to treat these lesions thanks to their wide and direct visualization of the entire skull base defect following the encephalocele excision, allowing an adequate multilayer repair and lateral sphenoid recess occlusion.

  7. Do alcohol excise taxes affect traffic accidents? Evidence from Estonia.

    Science.gov (United States)

    Saar, Indrek

    2015-01-01

    This article examines the association between alcohol excise tax rates and alcohol-related traffic accidents in Estonia. Monthly time series of traffic accidents involving drunken motor vehicle drivers from 1998 through 2013 were regressed on real average alcohol excise tax rates while controlling for changes in economic conditions and the traffic environment. Specifically, regression models with autoregressive integrated moving average (ARIMA) errors were estimated in order to deal with serial correlation in residuals. Counterfactual models were also estimated in order to check the robustness of the results, using the level of non-alcohol-related traffic accidents as a dependent variable. A statistically significant (P traffic accidents was disclosed under alternative model specifications. For instance, the regression model with ARIMA (0, 1, 1)(0, 1, 1) errors revealed that a 1-unit increase in the tax rate is associated with a 1.6% decrease in the level of accidents per 100,000 population involving drunk motor vehicle drivers. No similar association was found in the cases of counterfactual models for non-alcohol-related traffic accidents. This article indicates that the level of alcohol-related traffic accidents in Estonia has been affected by changes in real average alcohol excise taxes during the period 1998-2013. Therefore, in addition to other measures, the use of alcohol taxation is warranted as a policy instrument in tackling alcohol-related traffic accidents.

    2013-12-01

    Giant solitary submandibular duct calculus and multiple calculi of the gland are extremely rare. This occurrence along with more deep and proximally placed common calculi in submandibular gland may occasionally cause a dilemma in selection of the appropriate surgical approach in the present era of sialoendoscopic surgery. There is a high chance of fracture of the stone in a proximally placed stone in the gland followed by likely dissemination of fragments of the stone into the gland parenchyma during the procedure of sialoendoscopy which is a matter of grave concern. We authors believe that excision of the submandibular gland with the stone in such a situation should still be preferred as the gold standard of treatment leaving the ductal stone for endoscopic removal.

    DNA glycosylases preserve genome integrity and define the specificity of the base excision repair pathway for discreet, detrimental modifications, and thus, the mechanisms by which glycosylases locate DNA damage are of particular interest. Bacterial AlkC and AlkD are specific for cationic alkylated nucleobases and have a distinctive HEAT-like repeat (HLR) fold. AlkD uses a unique non-base-flipping mechanism that enables excision of bulky lesions more commonly associated with nucleotide excision repair. In contrast, AlkC has a much narrower specificity for small lesions, principally N3-methyladenine (3mA). Here, we describe how AlkC selects for and excises 3mA using a non-base-flipping strategy distinct from that of AlkD. A crystal structure resembling a catalytic intermediate complex shows how AlkC uses unique HLR and immunoglobulin-like domains to induce a sharp kink in the DNA, exposing the damaged nucleobase to active site residues that project into the DNA. This active site can accommodate and excise N3-methylcytosine (3mC) and N1-methyladenine (1mA), which are also repaired by AlkB-catalyzed oxidative demethylation, providing a potential alternative mechanism for repair of these lesions in bacteria.

    The surgical management of mammary intraductal papilloma without atypia (IDP) identified at core-needle biopsy (CNB) is controversial. This study assessed the rate of upgrade to carcinoma at surgical excision (EXC). This study identified women with a CNB diagnosis of intraductal papilloma without atypia or carcinoma at a cancer center between 2003 and 2013. Radiologic-pathologic concordance was assessed for all cases, and discordant cases were excluded. The radiologic and clinicopathologic features of patients with a CNB diagnosis of IDP were correlated with an upgrade to carcinoma at EXC. The study population consists of 189 women with 196 IDPs; 166 women (171 IDPs) underwent EXC. The upgrade rate was 2.3% (4 of 171). The upgraded 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 EXC and had stable imaging on follow-up (median, 23.5 months). The upgrade rate at EXC for IDPs diagnosed at CNB with radiologic-pathologic concordance was 2.3%. These findings suggest that observation is appropriate for patients with radiologic-pathologic concordant CNB yielding IDP, regardless of its size. Cancer 2016. © 2016 American Cancer Society.

    The capacity of preparations of skin fibroblasts from normal individuals and patients with Fanconi's anemia to excise gamma-ray products of the 5,6-dihydroxydihydrothymine type from exogenous DNA was investigated. The excision capacity of whole-cell homogenates of fibroblasts from two of four patients with Fanconi's anemia was substantially below normal. This repair deficiency was further pronounced in nuclear preparations from c
