One-piece resection is considered to be a gold standard of EMR, as it provides accurate histological assessment and reduces the risk of local recurrence. Endoscopic submucosal dissection (ESD) is a new technique developed to obtain one-piece resection even for large and ulcerative lesions. The present study aims to identify the technical feasibility, operation time and complications from a large consecutive series. Methods:, We reviewed all patients with EGC who underwent ESD using the IT knife at National Cancer Center Hospital in the period between January 2000 and December 2003. Results:, During the study period of 4 years we identified a total of 1033 EGC lesions in 945 consecutive patients who underwent ESD using the IT knife. We found a one-piece resection rate (OPRR) of 98% (1008/1033). Our OPRR with tumor-free margins was 93% (957/1033). On subgroup analysis it was found to be 86% (271/314) among large lesions (, 21 mm) and 89% (216/243) among ulcerative lesions. The overall non-evaluable resection rate was 1.8% (19/1033). The median operation time was 60 min (range; 10,540 min). Evidence of immediate bleeding was found in 7%. Delayed bleeding after ESD was seen in 6% and perforation in 4% of the cases. All cases with complications except one were successfully treated by endoscopic treatment. Conclusion:, The present study shows the technical feasibility of ESD, which provides one-piece resections even in large and ulcerative EGC. [source] ANALYSIS OF COMPLICATIONS FOLLOWING SURGICAL TREATMENT OF BENIGN PAROTID DISEASE,ANZ JOURNAL OF SURGERY, Issue 3 2008S. A. Reza Nouraei Background: The objective of the study was to study the incidence of, and risk factors for developing complications following parotidectomy for benign disease, to improve preoperative patient counselling and better inform future surgical management. Methods: An 11-year retrospective review of 162 parotidectomies for benign disease, collecting and analysing data about presentation, investigations, surgical treatment, postoperative facial nerve function, Frey's syndrome and other surgical complications. Results: The mean age at presentation was 58 years. The commonest pathology was benign pleomorphic adenoma (43%), followed by Warthin's tumour (30%) and chronic sialadenitis (22%). Sialadenitis was a significant risk factor for facial nerve palsy and increased the incidence of salivary fistulas. Parotid duct ligation increased the risk of nerve palsy in the distribution of zygomatic and buccal branches. Operations for Warthin's tumour were associated with an increased risk of dysfunction of the cervical branch of the nerve. Half the patients had intraoperative facial nerve stimulation and this did not influence the likelihood of facial paresis. The recovery of facial nerve function showed a biphasic distribution, with 90% of patients having normal function within 12 months, followed by a slower recovery rate for up to 2 years. Conclusion: The incidence of postoperative complications was influenced by the pathology, with inflammatory lesions significantly increasing the risk of facial nerve dysfunction and other complications, but also by variations in surgical practice, such as parotid duct ligation. Overall, the incidence of permanent facial paralysis was less than 2%, but temporary nerve palsy was common at 40%, with most patients regaining normal function within 1 year of the operation. [source] COMPLICATIONS OF INTERNAL FIXATION IN PAEDIATRIC FRACTURESANZ JOURNAL OF SURGERY, Issue 10 2007Audi B. Widjaja Background: Most displaced fractures in children can be managed by closed treatment. Internal fixation of fractures is sometimes required to achieve satisfactory reduction with certain fractures. The aim of this study was to document the rate of complications associated with internal fixation of fractures in the paediatric age group. Methods: A retrospective study was carried out on 268 consecutive children who had internal fixation of fractures from January 2000 to July 2004. The complications were categorized as major or minor. Results: The average age was 9.2 years (range, 1.4,16.9). There were 327 fractures. Fifty-nine children had fractures of two bones. Humeral fractures accounted for 45.7% of fractures, forearm fractures 31.3%, tibial and fibular fractures 14.1% and femoral fractures 4.9%. There were 27 children (10%) with major complications and 49 children (18%) with minor complications. There were 18 children (6.7%) with both major and minor complications. A total of 66 (24.6%) children had complications. There were 23 children (8.5%) requiring further surgery. Conclusions: In this study, 24.6% of children had complications associated with internal fixation. The risk of complications should be considered when electing to proceed with surgical treatment. Closed treatment should always be attempted in children unless there is a good indication for internal fixation. [source] RISK FACTORS FOR POSTOPERATIVE PULMONARY COMPLICATIONS IN UPPER ABDOMINAL SURGERYANZ JOURNAL OF SURGERY, Issue 3 2007Fikret Kanat Background: Pulmonary complications are the most frequent cause of postoperative morbidity and mortality in upper abdominal surgery (UAS). We aimed to examine the influence of possible preoperative, operative and postoperative risk factors on the development of early postoperative pulmonary complications (POPC) after UAS. Methods: A prospective study of 60 consecutive patients was conducted who underwent elective UAS in general surgical unit. Each patient's preoperative respiratory status was assessed by an experienced chest physician using clinical examination, chest radiographs, spirometry and blood gas analysis . Anaesthetical risks, surgical indications, operation time, incision type, duration of nasogastric catheter and mobilization time were noted. Forty-eight hours after the operation, pulmonary examinations of the patients were repeated. Results: Postoperative pulmonary complications were observed in 35 patients (58.3%). The most common complication was pneumonia, followed by pneumonitis, atelectasis, bronchitis, pulmonary emboli and acute respiratory failure. The presence of preoperative respiratory symptoms and the spirometric parameter of forced expiratory volume in 1 s/forced vital capacity were the most valuable risk factors for early prediction of POPC. The sensitivity, specificity and diagnostic efficiency of the presence of preoperative respiratory symptoms in the POPC prediction were 70, 61 and 66%, respectively. Conclusion: We recommend a detailed pulmonary examination and spirometry in patients who will undergo UAS by chest physicians to identify the patients at high risk for POPC, to manage respiratory problems of the patients before surgery and also to help surgeons to take early measures in such patients before a most likely POPC occurrence. Improvement of lung function in those patients at risk for POPC before operation may decrease morbidity in surgical patients. [source] THE NATURE OF FIRE AND ITS COMPLICATIONS: THEOPHRASTUS' DE IGNE 1,10BULLETIN OF THE INSTITUTE OF CLASSICAL STUDIES, Issue 1 2010MARLEIN VAN RAALTE This article offers a running commentary on De igne 1,10 (with text and translation). The way in which Theophrastus sets out to ascribe to the simple body of fire characteristics of terrestrial, burning fire, and only gradually dismisses his focus on fire (and its alter ego of heat) as a principle seems to indicate an early stage of his thought. On the other hand, a formal analysis of the text shows that the argument bears an unmistakably Theophrastean stamp. Finally it is argued that it cannot be inferred from De igne that Theophrastus adhered to the Aristotelian concept of aithêr, and that it is also very unlikely that he did so. The relevant passages from Theophrastus' botanical treatises and Metaphysics confirm this picture. Even the quite explicit testimonies from Philoponus and Julian seem to allow of an interpretation that does not involve Theophrastus having adopted this Aristotelian concept. [source] Design, surgical technique and complications MOOKPACTA OPHTHALMOLOGICA, Issue 2009GC FALCINELLI Purpose To describe design, surgical technique of the modified osteo-odonto-keratoprosthesis (MOOKP),originated from Strampelli's OOKP, with the modifications and the innovations made by Falcinelli, between these thoseones of the last years to the first stage of the procedure, never published. Methods First stage:abstraction of the mono-rooted tooth with surrounding root and bone. Preparation of the lamina to which, in the dentine central part,the PMMA optic cylinder is glued.Burying of the lamina for 3 months (subcutaneoos pocket). New modification:opening of the A.C., complete removal of the iris, lens cryo-extraction,anterior vitrectomy.Intermediate stage: after 1 month covering of the eye surface by buccal mucosa. Final stage: after3 months implant of the lamina on the eye with insertion in A.C. of the cylinder after corneal trephining,covering with buccal mucosa previously detached. Results MOOKP COMPLICATIONS- 1- Intraoperative, easy to be cured. 2- After the 1st stage and intermediate stage: all easily treatable. 3- After the prosthesis implant, more severe: a) Prosthesis complications which affect mainly the mucosa, easy to be cured, or the lamina and the cylinder, more rare, difficult to be cured. b) Eye complications: retinal detachment, not frequent and easily cured. Retroprosthetic membranes, very rare. Endophthalmites, very difficult to treat, fortunately rare. Conclusion Biological properties Strampelli's osteo-odonto lamina (OOL)with Falcinelli's surgical modifications make of MOOKP a KPro with best results, teorically without duration limits in the less and in the very severe cases of corneal and anterior oculare surfice alterations like the last stage of dray eye. [source] ROLE OF MACROPHAGES IN COMPLICATIONS OF TYPE 2 DIABETESCLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, Issue 10 2007GH TeschArticle first published online: 15 AUG 200 SUMMARY 1Macrophage accumulation is a feature of Type 2 diabetes and is associated with the development of diabetic complications (nephropathy, atherosclerosis, neuropathy and retinopathy). The present article reviews the current evidence that macrophages contribute to the complications of Type 2 diabetes. 2Macrophage-depletion studies in rodent models have demonstrated a causal role for macrophages in the development of diabetic complications. 3Components of the diabetic milieu (high glucose, advanced glycation end-products and oxidized low-density lipoprotein) promote macrophage accumulation (via induction of chemokines and adhesion molecules) and macrophage activation within diabetic tissues. 4Macrophages mediate diabetic injury through a variety of mechanisms, including production of reactive oxygen species, cytokines and proteases, which result in tissue damage leading to sclerosis. 5A number of existing and experimental therapies can indirectly reduce macrophage-mediated injury in diabetic complications. The present article discusses the use of these therapies, given alone and in combination, in suppressing macrophage accumulation and activity. 6In conclusion, current evidence supports a critical role for macrophages in the evolution of diabetic complications. Present therapies are limited in slowing the progression of macrophage-mediated injury. Novel strategies that are more specific at targeting macrophages may provide better protection against the development of Type 2 diabetic complications. [source] Clinical investigation of traumatic injuries in Yeditepe University, Turkey during the last 3 yearsDENTAL TRAUMATOLOGY, Issue 4 2005Nuket Sandalli Abstract,,, The aim of this study was to evaluate etiology, types of traumatic dental injuries, treatment and to determine the incidence of complications according to dental injuries in patients who referred to Yeditepe University, Faculty of Dentistry, Istanbul, Turkey. The study was based on the clinical data of the 161 traumatized teeth in 92 patients. WHO classification slightly modified by Andreasen & Andreasen for dental trauma was used. The causes and localization of trauma, traumatized teeth classification, treatment and complications were evaluated both primary and permanent teeth. The distribution of complications according to diagnosis and treatment of the injured teeth were evaluated. Of 35 (38%) girls and 56 (72%) boys with a mean age 7.6 ± 3.5 (ranging 1,14.2) participated to study and the mean followed up was 1.72 ± 1.28 years (ranging 0.10,3.8 years). From the 161 affected teeth, 69 (42.9%) were in primary teeth and 92 (57.1%) in permanent teeth. The highest frequency of trauma occurred in the 6,12 year age group. Overall boys significantly outnumbered girls by approximately 1:1.6. The most common type of injury in the primary and permanent teeth was seen as luxation (38%) and enamel fracture (20%) of the maxillary central incisors, respectively. Falls were the major sources of trauma both the primary (90%) and the permanent teeth (84%). In the primary dentition, the most common type of soft tissue injury is contusion (62.5%) and in the permanent dentition, it is laceration (49%). The most of the treatment choice was determined as examination only and extraction in primary teeth (58 and 24.6%, respectively) while it was applied as restoration and pulpectomy in permanent teeth (31.5 and 18.5%, respectively). Complications were recorded on 37 teeth (23%) with a most common type of necrosis (10.5%) and dental abscess (7.4%). Necrosis was more frequent in luxation whereas dental abscess were in crown fracture with pulpal involvement in both dentitions. The study showed that boys were more prone to dental traumas than girls. Falls were more frequent trauma type with a high complication risk. It reveals that the time of the immediate treatment showed the important predisposing factors that increase the success of treatment and decrease the risk of complication. The correct diagnosis of dental injuries is more important for eliminating the occurrence of complications. [source] Single-tooth implant treatment in the anterior region of the maxilla for treatment of tooth loss after trauma: a retrospective clinical and interview studyDENTAL TRAUMATOLOGY, Issue 3 2003Lars Andersson Abstract,,, The aim of this study was to evaluate the results of single-tooth implant treatment in patients where teeth have been lost as a result of trauma. Also, the patients' and professionals' opinions regarding the final outcome of treatment were assessed. Thirty-four patients with 42 lost teeth were evaluated by clinical and radiographic examinations and interviews 2,5 years after treatment. A professional who had not taken part in the treatment evaluated the implant crowns. Central maxillary incisors were the most frequently lost and replaced teeth after trauma (75%) followed by lateral incisors (21%). In patients with incomplete growth, implant treatment was generally postponed until completion of growth. Lack of space was treated by presurgical orthodontics (7%) or by selecting an implant with a reduced diameter (5%). Deficiency of bone was seen in 17% and was treated by bone grafting or local augmentation prior to implant surgery. Patients who had lost two or more teeth after trauma were all subjected to bone grafting. Preservation of roots in the alveolar process seemed to maintain the bone volume enabling better conditions for later implant placement. Forty-one implants (97.6%) were integrated successfully. Complications were few and of minor importance (9.5% before and 12% after cementation of crowns) and could all be managed. No or minimal bone loss was seen. In general, the patients felt that they received good care and that they were well informed about their treatment. Some patients reported that the local anesthesia procedure was not pain-free, but 71% of the patients experienced the treatment as pain-free. For each of the variables (color, shape, height, and size of the crowns), the highest degree of satisfaction was noted in 93,98% of the patients and 91,95% of the single evaluating professional. Given that the patients have finished growth and a careful treatment planning and timing are performed, the functional and esthetical outcome of single-tooth implant treatment today is excellent and can be recommended for replacing tooth losses after trauma in the anterior region of the maxilla. [source] Complications of Sclerotherapy: An UpdateDERMATOLOGIC SURGERY, Issue 2010FACPH, JEAN-JÉRÔME GUEX MD OBJECTIVES To describe, determine the incidence of, and explain the adverse reactions associated with the use of sclerotherapy and sclerosing agents. MATERIAL AND METHODS Review of current literature and personal research, with special attention to the French registry of 12,173 sclerotherapy sessions. RESULTS The nature and incidence of side effects of sclerosing agents vary according to the injection form: liquid or foam. They must be differentiated from complications of the method, which are less specific and often related to an inappropriate technique. Severe adverse events are rare, especially in relation to the billions of injections administered. CONCLUSION Complications and side effects of sclerotherapy are uncommon; the method has demonstrated its safety, with 0.22% of complications per session with liquid sclerosant and 0.58% with foamed sclerosant, but several points remain unclear, and more research is needed. Patient's informed consent can be better obtained thanks to the current knowledge herein summarized. Jean-Jérôme Guex, MD, FACPh, has received an honorarium from Bioform (USA). [source] Fractionated Laser Skin Resurfacing Treatment Complications: A ReviewDERMATOLOGIC SURGERY, Issue 3 2010ANDREI I. METELITSA MD BACKGROUND Fractional photothermolysis represents a new modality of laser skin resurfacing that was developed to provide a successful clinical response while minimizing postoperative recovery and limiting treatment complications. OBJECTIVES To review all of the reported complications that develop as a result of fractional ablative and nonablative laser skin resurfacing. METHODS A literature review was based on a MEDLINE search (1998,2009) for English-language articles related to laser treatment complications and fractional skin resurfacing. Articles presenting the highest level of evidence and the most recent reports were preferentially selected. RESULTS Complications with fractional laser skin resurfacing represent a full spectrum of severity and can be longlasting. In general, a greater likelihood of developing post-treatment complications is seen in sensitive cutaneous areas and in patients with intrinsically darker skin phototypes or predisposing medical risk factors. CONCLUSIONS Although the overall rate of complications associated with fractional laser skin resurfacing is much lower than with traditional ablative techniques, recent reports suggest that serious complications can develop. An appreciation of all of the complications associated with fractional laser skin resurfacing is important, especially given that many of them can be potentially prevented.

[source] Utility of Intralesional Sclerotherapy with 3% Sodium Tetradecyl Sulphate in Cutaneous Vascular MalformationsDERMATOLOGIC SURGERY, Issue 3 2010MNAMS, SUJAY KHANDPUR MBBS BACKGROUND Vascular malformations have devastating cosmetic effects in addition to being associated with pain and bleeding. Sclerotherapy has been successfully used in treating complicated hemangiomas and vascular malformations. OBJECTIVES To assess the efficacy of sclerotherapy with 3% sodium tetradecyl sulphate (STS) in venous and lymphatic malformations. MATERIALS AND METHOD We performed sclerotherapy with 3% STS in 13 patients with venous malformations and microcystic lymphatic malformation, all low-flow malformations and with extent predominantly to the subcutis, confirmed using Doppler ultrasound. Lesions were located on the face, lower lip, flanks, buttocks, and extremities. Patients presented for cosmetic reasons, pain, or bleeding. Sclerotherapy was undertaken as an office procedure without any radiological guidance and therapy repeated every 3 weeks. Therapeutic efficacy was assessed subjectively clinically and photographically. RESULTS The lesions regressed by 90% to 100% in 11 cases after a mean of four injections, with no improvement in two cases (one each of venous malformation and lymphatic malformation). Complications included cutaneous blister formation, erosions, and crusting at injection site in seven cases and atrophic scarring in four patients. CONCLUSIONS Sclerotherapy with 3% STS is a simple, safe, and effective modality for venous malformations and can be undertaken as an office procedure in lesions limited to the subcutis. The authors have indicated no significant interest with commercial supporters. [source] The Nature of Long-Term Fillers and the Risk of ComplicationsDERMATOLOGIC SURGERY, Issue 2009FAAD, GARY D.

McGUIRE BS BACKGROUND The upper third of the face is integral to our perception of youth and beauty. While the eyelids anchor this facial cosmetic unit, the eyebrows and forehead are intrinsically linked to the upper eyelids, and their position and texture play an important role in creating pleasing eyes as well as conveying mood and youth. The most common browlifts are performed with endoscopic visualization. Yet, this technique requires special equipment and a prolonged learning curve. OBJECTIVE To demonstrate a novel pretrichial technique and to review different browlift methods and their potential adverse effects. METHODS Case series and review of the literature. RESULTS The pretrichial browlift results in a mild to moderate browlift with secondary smoothing of the forehead topography. Aside from bruising and swelling, it results in minimal adverse effects. Other techniques are also effective but may create a larger scar such as a direct browlift, may be more difficult in terms of approach such as the browpexy, or require endoscopes. CONCLUSION Browlifts are an important procedure in rejuvenating the upper third of the face and improving the overall facial aesthetic appearance. The pretrichial browlift is a less invasive open technique that is safe and effective for the appropriate patient. [source] Complications of Minor Skin Surgery Performed under Local AnesthesiaDERMATOLOGIC SURGERY, Issue 8 2008AVSHALOM SHALOM MD BACKGROUND Minor surgical procedures performed under local anesthesia are the most common surgical procedures routinely carried out in every plastic surgical practice. OBJECTIVE The objective was to evaluate the prevalence of immediate local and systemic complications of such procedures. METHODS AND MATERIALS Records of 2,600 procedures performed under local anesthesia on 2,431 patients between November 2001 and May 2004 were reviewed. Local anesthetic complications and all surgical-related complications were recorded. RESULTS Procedure-related complications were 51 presyncope (1.9%), 4 true syncope (0.16%), 2 minor burns (0.08%), and 1 facial laceration (0.04%). CONCLUSIONS True allergic reaction to lidocaine is extremely rare and none was noted in our study. Most patients who claimed that they had suffered from such a reaction were probably experiencing symptoms related to intravenous injection administration, a reaction to the added vasoconstrictor (adrenaline), or a vasovagal reaction, which is a common trait among young adults. [source] Side Effects and Complications of Fractional Laser Photothermolysis: Experience with 961 TreatmentsDERMATOLOGIC SURGERY, Issue 3 2008EMMY M. GRABER MD BACKGROUND A novel 1,550-nm erbium-doped laser (Fraxel, Reliant Technologies Inc.) has been shown to be effective in the treatment of photodamaged skin and scars with minimal postoperative recovery; however, studies evaluating its side effects and complication rates have been limited. PURPOSE The purpose was to determine the frequency and range of side effects and complications associated with fractional photothermolysis treatment. METHODS A retrospective evaluation of 961 successive 1,550-nm erbium-doped laser treatments in patients of various skin phototypes (I,V) was conducted in a single center. Side effects and complications of treatment, including time of onset and duration, were identified and tabulated. Patient demographics and laser parameters were also assessed. RESULTS Seventy-three treatments (7.6%) resulted in development of complications. The most frequent complications were acneiform eruptions (1.87%) and herpes simplex virus outbreaks (1.77%). Side effects and complications were equally distributed across different ages, skin types, body locations, laser parameters, and underlying skin conditions, except for postinflammatory hyperpigmentation, which occurred with increased frequency in patients with darker skin phototypes. CONCLUSIONS Fractional laser skin treatment is associated with a relatively low complication rate. Side effects and complications observed in this study were temporary and did not result in long-term or significantly severe sequelae (e.g., scarring). [source] Early and Late Complications after a Nonabsorbable Hydrogel Polymer Injection: A Series of 14 Patients and Novel ManagementDERMATOLOGIC SURGERY, Issue 2007OREN GOLDAN MD First page of article [source] Sentinel Lymph Node Biopsy in Cutaneous Squamous Cell Carcinoma: A Systematic Review of the English LiteratureDERMATOLOGIC SURGERY, Issue 11 2006AMY SIMON ROSS MD BACKGROUND Although most cutaneous squamous cell carcinoma (SCC) is curable by a variety of treatment modalities, a small subset of tumors recur, metastasize, and result in death. Although risk factors for metastasis have been described, there are little data available on appropriate workup and staging of patients with high-risk SCC. OBJECTIVE We reviewed reported cases and case series of SCC in which sentinel lymph node biopsy (SLNB) was performed to determine whether further research is warranted in developing SLNB as a staging tool for patients with high-risk SCC. METHODS The English medical literature was reviewed for reports of SLNB in patients with cutaneous SCC. Data from anogenital and nonanogenital cases were collected and analyzed separately. The percentage of cases with a positive sentinel lymph node (SLN) was calculated. False negative and nondetection rates were tabulated. Rates of local recurrence, nodal and distant metastasis, and disease-specific death were reported. RESULTS A total of 607 patients with anogenital SCC and 85 patients with nonanogenital SCC were included in the analysis. A SLN could not be identified in 3% of anogenital and 4% of nonanogenital cases. SLNB was positive in 24% of anogenital and 21% of nonanogenital patients. False-negative rates as determined by completion lymphadenectomy were 4% (8/213) and 5% (1/20), respectively. Most false-negative results were reported in studies from 2000 or earlier in which the combination of radioisotope and blue dye was not used in the SLN localization process. Complications were reported rarely and were limited to hematoma, seroma, cutaneous lymphatic fistula, wound infection, and dehiscence. CONCLUSIONS Owing to the lack of controlled studies, it is premature to draw conclusions regarding the utility of SLNB in SCC. The available data, however, suggest that SLNB accurately diagnoses subclinical lymph node metastasis with few false-negative results and low morbidity. Controlled studies are needed to demonstrate whether early detection of subclinical nodal metastasis will lead to improved disease-free or overall survival for patients with high-risk SCC. [source] Nonablative Laser Surgery for Pigmented SkinDERMATOLOGIC SURGERY, Issue 10 2005David J. Goldberg MD Background. Nonablative laser surgery has been proven to improve early photodamaged skin and acne scars. These techniques include treatments with lasers, light sources, and/or radiofrequency devices. Objectives. To review the history of nonablative technology and its applicability to darker skin types and to provide an objective look at the various published studies documenting the efficacy of nonablative technology. Conclusion. Nonablative laser surgery can improve skin quality and acne scars in all skin types. Complications are rare but can occur. Future studies are required to compare the efficacy of the various nonablative technologies. DAVID J. GOLDBERG, MD, HAS INDICATED NO SIGNIFICANT INTEREST WITH COMMERCIAL SUPPORTERS. [source] Immediate and Midterm Complications of Sclerotherapy: Report of a Prospective Multicenter Registry of 12,173 Sclerotherapy SessionsDERMATOLOGIC SURGERY, Issue 2 2005FACPH, Jean-Jérôme Guex MD Background Growing interest in sclerotherapy has emphasized the need for complete knowledge of all aspects of this method. Objective To precisely delineate the actual incidence of immediate and delayed untoward events of daily sclerotherapy. Methods A multicenter prospective registry was established in 22 phlebology clinics to report their activity and complications. Results During the study period, 12,173 sessions of sclerotherapy were carried out, 5,434 with liquid, 6,395 with foam, and 344 using both. Four thousand eighty-eight (33.9%) sessions were carried out with ultrasound guidance. Forty-nine incidents or accidents (0.4%) occurred, of which 12 were with liquid and 37 with foam. These were reported during the time of the study and an additional 1-month follow-up. Most numerous were 20 cases of visual disturbances (in 19 cases, foam or air block was used); all resolved shortly, without any after-effects. A femoral vein thrombosis was the only severe adverse event in this study. Conclusions This study demonstrates that sclerotherapy is a safe technique.

[source] Complications from Injectable Polyacrylamide Gel, a New Nonbiodegradable Soft Tissue FillerDERMATOLOGIC SURGERY, Issue 12p2 2004Snehal P. Amin Background. Polyacrylamide gels, containing a hydrogel composed of polyacrylamide and water, are used for soft tissue augmentation and contour correction. There are no reports of significant complications after injection of this material into the face. Objective. We report an inflammatory reaction after injection of polyacrylamide gels for zygomatic facial augmentation. Methods. A retrospective chart review of single case is presented. Results. An inflammatory reaction at the sites of polyacrylamide gels injection was noted at 1 month after initial injection. Despite two ensuing courses of broad-spectrum antibiotics, the patient presented to us with persistent draining nodules. Intralesional steroid injections resulted in prompt resolution and no recurrence. Conclusion. Inflammatory reactions have been noted in patients receiving polyacrylamide gels for breast augmentation. Facial polyacrylamide gels injections may also be associated with an inflammatory reaction that responds to intralesional steroids. With increasing availability of a variety of soft tissue fillers, dermatologists should be aware of this delayed complication from polyacrylamide gels. [source] Sclerosing Foam in the Treatment of Varicose Veins and Telangiectases: History and Analysis of Safety and ComplicationsDERMATOLOGIC SURGERY, Issue 1 2002Alessandro Frullini MD objective. To review the use of sclerosing foam in the treatment of varicose veins, to describe the different techniques of foam preparation, and to report the complications of our 3-year experience with this treatment. method. From November 1997 to the end of October 2000, 453 patients were treated with a sclerosing foam for large, medium, and minor varicosities with sodium tetradecylsulfate (STS) or polidocanol (POL). A first group of 257 patients (90 for minor varicosities and 167 for medium to large veins) received a sclerosing foam according to the Monfreux technique. From December 1999 to October 2000, 196 patients were treated with a sclerosing foam prepared according to Tessari's method (36 for minor size veins or teleangectasias and 170 for medium-large veins). Every patient was studied with (color-flow) duplex scanning before and after the treatment and large vein injections were administered under duplex guide. results. The immediate success rate was 88.1% in the first group for the medium-large veins. In the same districts we registered an early success rate in 93.3% for the patients treated with the Tessari's method. The complication rate (mostly minor complications) was 8.5% in the first group and 7.1% in the second group. conclusion. The use of sclerosing foam may become an established therapy in the treatment of varicose veins with a high success rate, low cost, and low major complication rate. According to our actual experience and knowledge, the safe amount of foam should not exceed the 3-ml limit, but further advancements could come from standardization of the foam preparation technique.

Brody MD Implantation of the expanded polytetrafluoroethylene (e-PTFE) implant to achieve correction of nasolabial folds or thinning lip has been fraught with complications in spite of patient acceptance since its introduction in 1997. The four most frequent postoperative complications are extrusion, movement, infection, and swelling. In examination of 86 insertions of the 3.2 mm tubular implants, these sequelae are generally manageable for the physician and patient. If the patient understands possible courses of healing, both physician and patient satisfaction may be achieved.

The realm of nail unit surgery encompasses the dermatologist as well as the hand surgeon. Nail surgery complications may include allergy to anesthetic, infection, hematoma, nail deformity, and persistent pain and swelling. Objective. To review the pertinent literature regarding nail unit surgery complications. Methods. A Medline literature search was performed for relevant publications. Results. Nail unit surgery complications appear to be relatively infrequent. The majority of postoperative nail deformity complications result from nail matrix damage. Conclusion. Complications may be reduced to a minimum by preventive measures, such as careful patient selection, sterile technique, and gentle treatment of the nail matrix. [source] Long-Term Follow-Up After Autologous Fat Grafting: Analysis of Results from 116 Patients Followed at Least 12 Months After Receiving the Last of a Minimum of Two TreatmentsDERMATOLOGIC SURGERY, Issue 12 2000Sorin Eremia MD Background. The effectiveness of long-term results for correction of facial rhytides with single or multiple autologous fat transplants remains controversial. Objective. This study is a retrospective review of short- and long-term results for 116 patients who underwent multiple autologous fat grafting sessions into the nasolabial and melolabial (lateral oral commissure) fold, and in some cases additional sites such as lips and glabella. Methods. Criteria for inclusion into the study included at least two treatment sessions and at least a 12-month follow-up evaluation after the last treatment received. A 14-gauge needle cannula was used to aspirate the donor fat and to inject the fat grafts. Results. For the nasolabial and melolabial folds, short-term results at 3,4 months were uniformly excellent. Gradual correction loss was noted between 5 and 8 months, with 25% of patients still rated as excellent and 40% as good. Most patients continued to show correction loss between 9 and 14 months. Only 3,4% of the patients truly maintained long-term correction for more than 14 months. Multiple re-treatments did not significantly increase the percent of patients showing long-term results. For the glabella, the results were very disappointing, with most patients showing complete loss of correction after 3,4 months. For lip augmentation, correction loss was slower than in the glabella, but most patients showed complete loss of correction by 5,8 months. Complications were minimal. Conclusion. Autologous fat grafting is most effective for relatively short-term improvement of facial aging changes in the nasolabial and oral commissures areas. It is less effective for lip augmentation and completely ineffective for the glabella area. [source] Proximal femoral resection for subluxation or dislocation of the hip in spastic quadriplegiaDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 7 2003Steve Ackerly MD Management of a painful or contracted hip dislocation in individuals with severe spastic quadriplegia is difficult. Clinical and radiographic results of 12 proximal femoral resection-interposition operations performed in seven non-ambulatory persons (five males, two females; mean age 14 years, 8 months; age range 6 years 11 months to 19 years 8 months) with severe spasticity were reviewed to determine if pain relief and restoration of motion were maintained. At a mean follow-up of 7 years 7 months (median 9 years 6 months) all participants maintained a good sitting position and a functional range of motion with improved hygiene. Hip pain was improved in all participants compared with their preoperative status. Proximal femur migration occurred causing slight pain in one person. Heterotopic ossification was observed but was not clinically significant. Complications included traction pin loosening and infection and a late supracondylar femur fracture 3 months after the operation. Proximal femoral resection effectively decreased pain and restored hip motion in those with severe spastic quadriplegia leading to improved sitting and perineal care.
