Fisher MD Objective:. To ascertain the immediate and short-term side effects of fractional photothermolysis for the treatment of a variety of skin disorders involving the face, neck, chest, and hands. Methods. Physician-administered questionnaires were given during 60 follow-up visits for fractional photothermolysis treatment for a variety of facial skin disorders in patients with skin types ranging from I to IV. The questionnaire addressed 14 possible side effects, pain, and limitation of social activities. In addition, all patients were asked about any additional side effects not mentioned in the survey. An analysis of the data was performed once 60 surveys had been collected. Results. All patients (100%) undergoing fractional photothermolysis had transient post-treatment erythema. Other frequently reported post-treatment side effects were transient and included facial edema (82%), dry skin (86.6%), flaking (60%), a few (one to three) small, superficial scratches (46.6%), pruritis (37%), and bronzing (26.6%). Other more rarely reported effects included transient increased sensitivity (10%) and acneiform eruption (10%). Most patients reported that the pain level was easily tolerated, with an average pain score of 4.6 on a scale of 10. Most patients (72%) reported limiting social engagements for an average of 2 days after treatment. There were no long-lasting adverse events noted in our survey. Conclusion. Fractional photothermolysis to treat dermatologic conditions on the face, neck, chest, and hands is a well-tolerated and safe procedure with several immediate, and slightly delayed, post-treatment side effects. In our experience, these side effects were transient and limited to erythema, edema, dry skin, flaking skin, superficial scratches, pruritis, increased sensitivity, and acneiform eruption. Importantly, we did not see the development of post-treatment scarring, herpetic activation, hypopigmentation, hyperpigmentation, persistent erythema, persistent edema, or infection. [source] Tumescent Liposuction Report Performance Measurement Initiative: National Survey ResultsDERMATOLOGIC SURGERY, Issue 7 2004William Hanke MD Background. This study was created by the Accreditation Association for Ambulatory Health Care Institute for Quality Improvement to measure clinical performance and improvement opportunities for physicians and ambulatory health-care organizations. Data were collected prospectively between February 2001 and August 2002. Thirty-nine study centers participated, and 688 patients who had tumescent liposuction were surveyed and followed for 6 months. Objective. The objective was to determine patient satisfaction with tumescent liposuction and examine current liposuction practice and the safety of tumescent liposuction in a representative cohort of patients. Methods. The Accreditation Association for Ambulatory Health Care Institute for Quality Improvement collected prospective data from February 2001 to August 2002 from 68 organizations registered for this study. Ultimately 39 organizations submitted 688 useable cases performed totally with local anesthesia, "tumescent technique." Results. The overall clinical complication rate found in the Accreditation Association for Ambulatory Health Care Institute for Quality Improvement study was 0.7% (5 of 702). There was a minor complication rate of 0.57%. The major complication rate was 0.14% with one patient requiring hospitalization. Seventy-five percent of the patients reported no discomfort during their procedures. Of the 59% of patients who responded to a 6-month postoperative survey, 91% were positive about their decision to have liposuction (rating of 4 or 5 on a scale of 1,5) and 84% had high levels (4 or 5 on a scale of 1,5) of overall satisfaction with the procedure. Conclusions. Our findings are consistent with others in that tumescent liposuction is a safe procedure with a low complication rate and high patient satisfaction. [source] Bradycardia and sinus arrest during percutaneous ethanol injection therapy for hepatocellular carcinomaEUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 3 2004A. Ferlitsch Abstract Background, Percutaneous ethanol injection (PEI) is an established method in the treatment of hepatocellular carcinoma (HCC) and considered a safe procedure, with severe complications occurring rarely. Cardiac arrhythmias have not been reported to date. Aim of the study was to investigate the occurrence of dysrhythmias during PEI. Patients and methods, Twenty-six consecutive patients with inoperable HCC were included. During ultrasound-guided PEI with 95% ethanol, electrocardiogram (ECG) monitoring was performed before starting and continuously during PEI. Results, During PEI a significant reduction in mean heart rate (> 20%) was seen in 15 of 26 (58%) patients. In 11 of 26 patients (42%) occurrence of sinuatrial block (SAB) or atrioventricular block (AVB) was observed after a median time of 9 s (range 4,50) from the start of PEI with a median length of 24 s (range 12,480). Clinical symptoms were seen in two patients, including episodes of unconsciousness, seizure-like symptoms in both and a respiratory arrest during PEI in one patient, requiring mechanical ventilation. In four of 12 patients with repeat interventions, dysrhythmias were reproducible during monthly performed procedures. There was a significant association between the occurrence of SAB or AVB and the amount of instilled alcohol (P = 0·03) and post-PEI serum ethanol levels (P = 0·03). Conclusions, Bradycardia and block formation occur frequently during PEI. These symptoms could be explained by a vasovagal reaction and/or the direct effect of ethanol on the sinus node or the right atrial conduction system. Ethanol dose is an important factor for the occurrence of SAB/AVB. ECG-monitoring seems mandatory during PEI. Prophylactic use of intravenously administered Atropine might be useful. [source] Elective coronary angioplasty with 60 s balloon inflation does not cause peroxidative injuryEUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 3 2002K. Cedro Abstract Background The aim of this study was to evaluate the ongoing controversial issue of whether ischemia/reperfusion during elective coronary angioplasty evokes myocardial peroxidative injury. Design We measured indicators of free radical damage to lipids (free malondialdehyde) and proteins (sulphydryl groups) in coronary sinus blood in 19 patients with stable angina who were undergoing elective angioplasty for isolated stenosis of the proximal left anterior descending coronary artery. Ischemia induced by 60 s balloon inflations was confirmed by lactate washout into coronary sinus after deflation, with immediate and 1 min samples. Peroxidative injury was assessed from washout of (a) malondialdehyde measured directly by high performance liquid chromatography and (b) reduced sulphydryl groups, inverse marker of protein oxidative stress. Results Mean lactate concentration immediately after each deflation increased by 120,150% of the initial value, confirming ischemia and showing that blood originated largely from the ischemic region. Lack of myocardial production of malondialdehyde was confirmed by (a) no arteriovenous differences in individual basal concentrations (aortic, range 0·33,12·03 nmol mL,1, mean 7·82; coronary sinus blood, range 0·52,15·82 nmol mL,1, mean 8·18), and (b) after deflations, mean concentrations were not significantly different from preocclusion value. There was no decrease in concentration of sulphydryl groups throughout angioplasty. Conclusion Elective coronary angioplasty with 60 s balloon inflations is a safe procedure that does not induce peroxidative myocardial injury as assessed by methods used in the present study. [source] A systematic review on the diagnosis and treatment of primary (idiopathic) dystonia and dystonia plus syndromes: report of an EFNS/MDS-ES Task ForceEUROPEAN JOURNAL OF NEUROLOGY, Issue 5 2006A. Albanese chairman To review the literature on primary dystonia and dystonia plus and to provide evidence-based recommendations. Primary dystonia and dystonia plus are chronic and often disabling conditions with a widespread spectrum mainly in young people. Computerized MEDLINE and EMBASE literature reviews (1966,1967 February 2005) were conducted. The Cochrane Library was searched for relevant citations. Diagnosis and classification of dystonia are highly relevant for providing appropriate management and prognostic information, and genetic counselling. Expert observation is suggested. DYT-1 gene testing in conjunction with genetic counselling is recommended for patients with primary dystonia with onset before age 30 years and in those with an affected relative with early onset. Positive genetic testing for dystonia (e.g. DYT-1) is not sufficient to make diagnosis of dystonia. Individuals with myoclonus should be tested for the epsilon-sarcoglycan gene (DYT-11). A levodopa trial is warranted in every patient with early onset dystonia without an alternative diagnosis. Brain imaging is not routinely required when there is a confident diagnosis of primary dystonia in adult patients, whereas it is necessary in the paediatric population. Botulinum toxin (BoNT) type A (or type B if there is resistance to type A) can be regarded as first line treatment for primary cranial (excluding oromandibular) or cervical dystonia and can be effective in writing dystonia. Actual evidence is lacking on direct comparison of the clinical efficacy and safety of BoNT-A vs. BoNT-B. Pallidal deep brain stimulation (DBS) is considered a good option, particularly for generalized or cervical dystonia, after medication or BoNT have failed to provide adequate improvement. Selective peripheral denervation is a safe procedure that is indicated exclusively in cervical dystonia. Intrathecal baclofen can be indicated in patients where secondary dystonia is combined with spasticity. The absolute and comparative efficacy and tolerability of drugs in dystonia, including anticholinergic and antidopaminergic drugs, is poorly documented and no evidence-based recommendations can be made to guide prescribing. [source] Ruptured pseudoaneurysm of the internal maxillary artery complicating CT-guided fine-needle aspiration in an irradiated, surgical bedHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 12 2007John C. Oh BA Abstract Background. CT-guided fine-needle aspiration (FNA) is a safe procedure, but major complications can occur rarely. Pseudoaneurysm rupture in the head and neck region following CT-guided FNA is an emergency that can result in life-threatening hemorrhage. This case emphasizes the salient risk factors for pseudoaneurysm formation and rupture in the head and neck region following CT-guided FNA. Methods. A patient was seen with oral and facial hemorrhage as a result of a ruptured pseudoaneurysm 11 weeks following CT-guided FNA in a previously irradiated surgical bed. Results. The patient was treated with coil embolization in and around the pseudoaneurysm and discharged without any further complications. Conclusions. Although CT-guided FNA is a safe and effective procedure, some patients may be at increased risk for rare but major complications. Caution should be used in proceeding with CT-guided FNA in an irradiated surgical bed of the head and neck. © 2007 Wiley Periodicals, Inc. Head Neck, 2007 [source] Results of laparoscopic splenectomy for treatment of malignant conditionsHPB, Issue 4 2001E M Targarona Background Laparoscopic splenectomy (LS) is widely accepted for treatment of benign diseases, but there are few reports of its use in cases of haematological malignancy. In addition, comparative studies with open operation are lacking. Malignant haematological diseases have specific clinical features - notably splenomegaly and impaired general health - which can impact on the immediate outcome after LS. The immediate outcome of LS comparing benign with malignant diagnoses has been analysed in a prospective series of 137 operations. Patients and methods Between February 1993 and April 2000, 137 patients with a wide range of splenic disorders received LS. Clinical data and immediate outcome were prospectively recorded, and age, diagnosis, operation time, perioperative transfusion requirement, spleen weight, conversion rate, accessory incision, hospital stay and complications were analysed. Results The series included 100 benign cases and 37 suspected malignancies. In patients with malignant diseases the mean age was greater (37 years [3,85] vs 60 years [27,82], p <0.01), LS took longer (138 min [60,400] vs 161 min [75,300], p <0.05) and an accessory incision for spleen retrieval was required more frequently (18% vs 93%, p <0.01) because the spleen was larger (279 g [60,1640] vs 1210 g [248,3100], p <0.01). However, the rate of conversion to open operation (5% vs 14%), postoperative morbidity rate (13% vs 22%) and transfusion requirement (15% vs 26%) did not differ between benign and malignant cases. Hospital stay was longer in malignant cases (3.7 days [2,14] vs 5 days [2,14], p <0.05). Conclusion LS is a safe procedure in patients with malignant disease requiring splenectomy in spite of the longer operative time and the higher conversion rate.

Gibbs No abstract is available for this article. [source] D2 gastrectomy , a safe operation in experienced hands,INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 6 2005R.S. Date Summary In the contemporary practice, surgery is the only potentially curative treatment available for gastric cancer. However, there is no consensus on the extent of surgical resection. Advantages of D2 gastrectomy in terms of morbidity, mortality, local recurrence and survival are confirmed in Japanese as well as some European trials. In our hospital, all patients with operable gastric cancer are treated with D2 gastrectomy along with splenectomy and distal pancreatectomy followed by jejunal pouch reconstruction. The study was undertaken to evaluate our practice in terms of postoperative morbidity and mortality. All the patients who had total gastrectomy for gastric carcinoma from January 1995 to December 2000 were included in the study. During this 6-year period, 33 patients underwent potentially curative D2 gastrectomy. Postoperative morbidity and mortality were 18 and 9%, respectively. There were no anastomotic leaks. Three (9%) patients developed dysphasia, of which two (6%) had anastomotic stricture requiring dilatation. We feel D2 gastrectomy with splenectomy and distal pancreatectomy when performed electively is a safe procedure in experienced hands. Oesophago-jejunal anastomosis can be safely performed using circular stapler. [source] Bilateral ankle arthritis with mediastinal lymphadenopathy: a clinician's perspectiveINTERNATIONAL JOURNAL OF RHEUMATIC DISEASES, Issue 3 2006Lalit DUGGAL Abstract Aim:, This study is a clinician's perspective of the association of bilateral ankle arthritis with mediastinal lymphadenopathy. Method:, Forty-three patients with bilateral ankle arthritis with mediastinal lymphadenopathy were included in a 14-month prospective follow-up study in our hospital. Complete history, examination and investigations were carried out. Result:, There were 27 female and 16 male patients. Ankle arthritis with tuberculous mediastinal lymphadenopathy was associated in 58.13%, sarcoidosis in 32.5% and 9.3% were non-specific. The patients were clustered in the spring-summer months. Erythema nodosum was found in 14.3%, polyarticular presentation in 25%. Thirteen out of 43 patients (28.2%) had biopsy/fine needle aspiration (FNA), of which 69.23% had histopathological evidence of tuberculosis. Conclusion:, The aetiology of bilateral ankle arthritis associated with mediastinal lymphadenopathy may be tuberculosis as opposed to sarcoidosis. There is a seasonal clustering of these cases. FNA of mediastinal lymphadenopathy is a fairly safe procedure and should be carried out when feasible, for confirmation of diagnosis. [source] Dorsal onlay augmentation urethroplasty with small intestinal submucosa: Modified Barbagli technique for strictures of the bulbar urethraINTERNATIONAL JOURNAL OF UROLOGY, Issue 11 2006IVO I DONKOV Aim: To present the results from one clinic's experience of using small intestinal submucosa (SIS) in augmentation urethroplasty for management of strictures of the bulbar urethra. Methods: Urethral surgery was performed in nine men with strictures 4,6 cm. All of the patients were evaluated by history, physical examination, retrograde urethrogram, and uroflowmetry. Four layers of SIS were soaked in saline or Ringer's solution for 15 minutes at 37°C, and the inner surface of the patch was gently fenestrated with a thin scalpel. The patch was spread-fixed onto the tunica albuginea. The mucosa was sutured to the submucosal graft first at 2,3 mm inwards from the SIS margins, then the spongiosum tissue was attached to the margins with interrupted absorbable sutures. Results: Of the nine patients who underwent augmentation urethroplasty using SIS, only one had re-stricture at 6 months due to urethral infection. At 18 months after the surgery the uroflowmetry of the other eight patients was 20,21 mL/s. In terms of complications, six patients reported having post-micturition dribbling, and seven patients reported lack of morning erections for 35,69 days after surgery. Conclusions: Using SIS is a safe procedure; however, long-term follow-up is needed to substantiate the good short-term results. [source] Hand-assisted retroperitoneoscopic radical nephrectomy: Initial experienceINTERNATIONAL JOURNAL OF UROLOGY, Issue 9 2002AKIHIRO KAWAUCHI Abstract Objectives: To report our initial experience of hand-assisted retroperitoneoscopic radical nephrectomy for stage T1 renal tumors. Methods: The clinical data on 22 consecutive patients who had undergone hand-assisted retroperitoneoscopic radical nephrectomy and 22 who had undergone open radical nephrectomy were reviewed. The operation was performed with a hand placed retroperitoneally through a pararectal longitudal 7,7.5 cm incision using a LAP DISC. Results: The total operating time was between 2.3 and 5.8 h (mean: 3.4 h). The estimated blood loss was between 15 and 650 mL (mean: 170 mL). The complication rate was 9% (2/22). No conversions to open procedure occurred. In comparison to open radical nephrectomy, the operating time was similar (3.4 vs 3.9 h) whereas the estimated blood loss was significantly less in this procedure (170 vs 495 mL). During the convalescence period the patients revealed significantly less postoperative pain, shorter intervals to resuming oral intake and more rapid return to normal activities compared to the open radical nephrectomy patients. Conclusion: Hand-assisted retroperitoneoscopic radical nephrectomy is an effective and safe procedure for T1 renal tumors. [source] Regional anticoagulation and antiaggregation for CVVH in critically ill patients: a prospective, randomized, controlled pilot studyACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 1 2010L. P. FABBRI Background: The aim of this study is to assess the efficacy and clinical safety of regional anticoagulation (heparin pre-filter plus post-filter protamine) plus antiaggregation (pre-filter prostacyclin) [Group 1 (G1)] vs. only systemic heparin anticoagulation without antiaggregation [Group 2 (G2)] in critically ill patients with acute renal failure undergoing continuous veno-venous haemofiltration (CVVH). Methods: One hundred and ten patients were randomized in a prospective, controlled pilot study. G1 patients received 1000 U/h pre-filter heparin, 10 mg/h post-filter protamine sulphate and 4 ng/kg/min pre-filter prostacyclin, while G2 patients received 1000 U/h pre-filter heparin. The haemofilter transmembrane pressure (TMP) and lifespan, as well as the platelet count were observed 1 h before, and at 6, 12, 18, 24 and 36 h from the beginning of CVVH. Results: Haemofilter TMP remained unchanged in G1 while it increased up to three times in G2 (P=0.0002). The median filter lifespan was 68 h in G1 and 19 h in G2. The rate of spontaneous circuit failure was 24% in G1 and 93% in G2 (P=0.0001). The platelet count was stable over the treatment period in G1 while in G2 it decreased progressively (P=0.0073). Conclusion: In critically ill patients suffering from acute renal failure, regional anticoagulation with pre-filter heparin and post-filter protamine plus antiaggregation during CVVH is a simple and safe procedure that prevents increases in filter TMP and increases circuit life time compared with systemic anticoagulation with pre-filter heparin only. [source] Predictors of Failure to Cure Atrial Fibrillation with the Mini-Maze OperationJOURNAL OF CARDIAC SURGERY, Issue 1 2004Zoltan A. Szalay M.D. A reduction in the number of right and left atrial incisions could decrease the operative time. The aim of this study was to assess the results of a mini-maze operation and to define predictors of its failure. Methods: Between 1995 and 2000, 72 patients (mean age 64 ± 9 years) undergoing cardiac surgery had a concomitant mini-maze operation for symptomatic chronic atrial fibrillation. Three and 12 months postoperatively, heart rhythm and left atrial transport functions were assessed by electrophysiology, echocardiography, and magnetic resonance imaging. Multivariate analysis was performed to identify predictors of failure of the mini-maze operation. Results: Operative mortality was 1.4% (1/72). Death during follow-up occurred in 5.6% of patients (4/71), in one due to chronic heart failure. After 1 year, 80% of patients (48/60) were either in sinus rhythm (n = 43; 72%) or had a pacemaker (n = 5; 8%) implanted due to sick sinus syndrome. Intermittent and chronic atrial fibrillation was found in 20% of patients (12/60). Preoperative duration of atrial fibrillation (p = 0.05), preoperative left atrial diameter (p = 0.001), preoperative right atrial diameter (p = 0.02), a reduced left ventricular ejection fraction (p = 0.03), an increased left ventricular end-diastolic diameter (p = 0.04), and the presence of mitral valve stenosis (p = 0.001) were found to be univariate predictors of failure of the mini-maze operation 1 year postoperatively. Multivariate analysis defined preoperative diagnosis of mitral valve stenosis (p = 0.005; OR 117.5), longer duration of preoperative atrial fibrillation (p = 0.01; OR 1.33), and increased preoperative left ventricular end-systolic diameter (p = 0.02; OR 1.2) as incremental independent risk factors for failure of the mini-maze operation to cure chronic atrial fibrillation. Conclusion: The mini-maze operation is a safe procedure with similar results to that of Cox's Maze-III operation. The less-invasive mini-maze operation could be applicable even to patients with severely reduced left ventricular function, in whom complex cardiac surgery has to be performed concomitantly as well as in those presenting severe comorbidities. (J Card Surg 2004;19:1-6) [source] Does the presence of a mesh have an effect on the testicular blood flow after surgical repair of indirect inguinal hernia?JOURNAL OF CLINICAL ULTRASOUND, Issue 2 2009Selma Uysal Ramadan MD Abstract Purpose. Modern treatment of inguinal hernias includes prosthetic mesh repairs. However, direct contact of the mesh to the vessels in the inguinal canal and perimesh fibrosis may have a negative impact on testicular flow. The aim of this prospective study was to evaluate the effect of mesh implantation/perimesh fibrosis on testicular flow after repair of indirect inguinal hernias (IIHs). Method. Forty-eight male patients with unilateral IIH were included. Both testicular parenchyma were assessed using gray-scale sonography, and color/spectral Doppler sonography was performed to evaluate testicular arterial impedance, perfusion, and venous flow. Measurements were made bilaterally at the level of the inguinal canal 1 day before and at the end of the 2nd month after the operation. Results. There was no difference in testicular and echotexture perfusion between the hernia and the control sides pre- and postoperatively. No venous thrombosis was found. In all groups, resistance index and pulsatility index, measured at 4 levels, were highest in the proximal inguinal canal and lowest at the extratesticular,intrascrotal level (p < 0.05). For all Doppler parameters there was no significant difference between the pre- and postoperative measurements on both the hernia and the control sides. Conclusion. Mesh implantation/perimesh fibrosis does not adversely affect ipsilateral testicular flow. Mesh application is still a safe procedure in male patients in whom testicular function is important. © 2008 Wiley Periodicals, Inc. J Clin Ultrasound, 2009 [source] Intratumoural chemotherapy of lung cancer for diagnosis and treatment of draining lymph node metastasisJOURNAL OF PHARMACY AND PHARMACOLOGY: AN INTERNATI ONAL JOURNAL OF PHARMACEUTICAL SCIENCE, Issue 3 2010Firuz Celikoglu Abstract Objectives Reviewed here is the potential effectiveness of cytotoxic drugs delivered by intratumoural injection into endobronchial tumours through a bronchoscope for the treatment of non-small cell lung cancer and the diagnosis of occult or obvious cancer cell metastasis to mediastinal lymph nodes. Key findings Intratumoural lymphatic treatment may be achieved by injection of cisplatin or other cytotoxic drugs into the malignant tissue located in the lumen of the airways or in the peribronchial structures using a needle catheter through a flexible bronchoscope. This procedure is termed endobronchial intratumoural chemotherapy and its use before systemic chemotherapy and/or radiotherapy or surgery may provide a prophylactic or therapeutic treatment for eradication of micrometastases or occult metastases that migrate to the regional lymph nodes draining the tumour area. Conclusions To better elucidate the mode of action of direct injection of cytotoxic drugs into tumours, we review the physiology of lymphatic drainage and sentinel lymph node function. In this light, the potential efficacy of intratumoural chemotherapy for prophylaxis and locoregional therapy of cancer metastasis via the sentinel and regional lymph nodes is indicated. Randomized multicenter clinical studies are needed to evaluate this new and safe procedure designed to improve the condition of non-small cell lung cancer patients and prolong their survival. [source] Assessment of open versus laparoscopy-assisted gastrectomy in lymph node-positive early gastric cancer: A retrospective cohort analysisJOURNAL OF SURGICAL ONCOLOGY, Issue 1 2010Ji Yeong An MD Abstract Background Laparoscopy-assisted gastrectomy (LAG) is still limited for early gastric cancer (EGC) with low possibility of lymph node (LN) metastasis, due to the concern for incomplete LN dissection and controversial long-term outcomes. We assessed oncological outcomes of laparoscopy-assisted versus open gastrectomy (OG) for patients with LN positive EGC. Methods Between 2003 and 2007, 204 patients underwent surgery for LN positive EGC. We evaluated adequacy of LN dissection and early and long-term outcomes after OG (n,=,162) and LAG (n,=,42). Results Operative time was longer but hospital stay was shorter for LAG than OG. Postoperative complications occurred in 14 patients (8.6%) after OG and 1 patient (2.4%) after LAG (P,=,0.316). Mean number of retrieved LNs and number of retrieved and metastatic LNs for each station did not differ between the two groups. During median 35 months of follow-up, 14 patients (8.6%) developed recurrence after OG, compared with 4 patients (9.5%) after LAG (P,=,0.769). Overall 5-year disease-free survival was 89.9% and 89.7% after OG and LAG. Status of LN metastasis was the only independent prognostic factor for disease-free survival. Conclusions LAG is an oncologically safe procedure even for LN positive EGC. Adequate LN dissection and comparable long-term outcomes to OG can be achieved by LAG. J. Surg. Oncol. J. Surg.

[source] European Federation of Neurological Societies/Peripheral Nerve Society Guideline on the use of skin biopsy in the diagnosis of small fiber neuropathy.JOURNAL OF THE PERIPHERAL NERVOUS SYSTEM, Issue 2 2010Report of a joint task force of the European Federation of Neurological Societies, the Peripheral Nerve Society Revision of the guidelines on the use of skin biopsy in the diagnosis of peripheral neuropathy, published in 2005, has become appropriate due to publication of more relevant papers. Most of the new studies focused on small fiber neuropathy (SFN), a subtype of neuropathy for which the diagnosis was first developed through skin biopsy examination. This revision focuses on the use of this technique to diagnose SFN. Task force members searched the Medline database from 2005, the year of the publication of the first EFNS guideline, to June 30th, 2009. All pertinent papers were rated according to the EFNS and PNS guidance. After a consensus meeting, the task force members created a manuscript that was subsequently revised by two experts (JML and JVS) in the field of peripheral neuropathy and clinical neurophysiology, who were not previously involved in the use of skin biopsy. Distal leg skin biopsy with quantification of the linear density of intraepidermal nerve fibers (IENF), using generally agreed upon counting rules, is a reliable and efficient technique to assess the diagnosis of SFN (level A recommendation). Normative reference values are available for bright-field immunohistochemistry (level A recommendation) but not yet for confocal immunofluorescence or the blister technique. The morphometric analysis of IENF density, either performed with bright-field or immunofluorescence microscopy, should always refer to normative values matched for age (level A recommendation). Newly established laboratories should undergo adequate training in a well established skin biopsy laboratory and provide their own stratified age and gender-matched normative values, intra- and interobserver reliability, and interlaboratory agreement. Quality control of the procedure at all levels is mandatory (Good Practice Point). Procedures to quantify subepidermal nerve fibers and autonomic innervated structures, including erector pili muscles, and skin vessels are under development but need to be confirmed by further studies. Sweat gland innervation can be examined using an unbiased stereologic technique recently proposed (level B recommendation). A reduced IENF density is associated with the risk of developing neuropathic pain (level B recommendation), but it does not correlate with its intensity. Serial skin biopsies might be useful for detecting early changes of IENF density, which predict the progression of neuropathy, and to assess degeneration and regeneration of IENF (level C recommendation). However, further studies are warranted to confirm the potential usefulness of skin biopsy with measurement of IENF density as an outcome measure in clinical practice and research. Skin biopsy has not so far been useful for identifying the etiology of SFN. Finally, we emphasize that 3-mm skin biopsy at the ankle is a safe procedure based on the experience of 10 laboratories reporting absence of serious side effects in approximately 35,000 biopsies and a mere 0.19% incidence of non-serious side effects in about 15 years of practice (Good Practice Point). [source] Prospective evaluation of flex-rigid pleuroscopy for indeterminate pleural effusion: Accuracy, safety and outcomeRESPIROLOGY, Issue 6 2007Pyng LEE Objective: This study aimed to assess prospectively the accuracy, safety and outcome of flex-rigid pleuroscopy in the diagnosis of patients with indeterminate pleural effusions. Methods: Included in the study were all patients with unilateral exudative pleural effusions of unknown aetiology who underwent diagnostic flex-rigid pleuroscopy from July 2003 to June 2005, and were followed until December 2005. The procedure was conducted in the endoscopy suite under local anaesthesia and, where indicated, talc poudrage was carried out at the same time. Clinical data, length of hospitalization, chest tube drainage, outcome, diagnostic accuracy of pleuroscopy and procedure-related adverse events were recorded prospectively. Results: Fifty-one patients were recruited (20 male and 31 female). Median age was 53 years (range 45,67). Flex-rigid pleuroscopy was 96% accurate and yielded a diagnosis in 49 out of 51 patients. It was safely carried out without need for surgical intervention, blood transfusion or endotracheal intubation. Culture-negative fever was observed in eight patients (16%), and five patients (10%) required additional analgesia for postoperative pain. Duration of chest tube drainage and length of stay for patients who underwent diagnostic pleuroscopy were 1 and 2 days, respectively, while they were both 3 days when talc poudrage was carried out. Success rates with pleuroscopic talc pleurodesis for malignant pleural effusions were 94%, 92% and 89.5% at 3, 6 and 12 months, respectively, and the 30-day mortality was 0%. Conclusion: Flex-rigid pleuroscopy is a safe procedure with a high diagnostic accuracy and should be considered for the evaluation of indeterminate pleural effusion. [source] ORIGINAL RESEARCH,SURGERY: Short Term Impact on Female Sexual Function of Pelvic Floor Reconstruction with the Prolift ProcedureTHE JOURNAL OF SEXUAL MEDICINE, Issue 11 2009Tsung-Hsien Su MD ABSTRACT Introduction., The Prolift system is an effective and safe procedure using mesh reinforcement for vaginal reconstruction of pelvic organ prolapse (POP), but its effect on sexual function is unclear. Aim., To evaluate the impact of transvaginal pelvic reconstruction with Prolift on female sexual function at 6 months post-operatively. Methods., Thirty-three sexually active women who underwent Prolift mesh pelvic floor reconstruction for symptomatic POP were evaluated before and 6 months after surgery. Their sexual function was assessed by using the short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) before and after surgery. The quality of life was also evaluated with the short forms of the Urogenital Distress Inventory (UDI-6) and the Incontinence Impact Questionnaire (IIQ-7) as a control for efficacy of the procedure. The Pelvic Organ Prolapse Quantification system was used to evaluate the degree of prolapse. Main Outcome Measures., PISQ-12 scores at 6 months post-operatively. Results., The total PISQ-12 score decreased from 29.5 ± 9.0 to 19.3 ± 14.7 (P < 0.001), indicating worsening of sexual function 6 months post-operatively. The behavioral, physical, and partner-related domains of PISQ-12 were each significantly reduced (5.2 ± 3.7 vs. 2.9 ± 3.7, P = 0.016; 15.4 ± 4.7 vs. 10.4 ± 8.6, P = 0.001; 8.9 ± 3.8 vs. 6.4 ± 5.5, P = 0.01, respectively). UDI-6 and IIQ-7 scores were significantly improved at the 6-month follow-up, as was anatomic recovery. Of the 33 subjects, 24 (73%) had worse sexual function 6 months after the procedure. Conclusion., The Prolift procedure provided an effective anatomic cure of POP, but it had an adverse effect on sexual function at 6 months after surgery.

[source] Conservative Management of Vestibular Schwannomas: An Effective Strategy,THE LARYNGOSCOPE, Issue 6 2008Gian Gaetano Ferri MD Abstract Objectives: Stimulated by the availability of a larger sample of patients and a longer follow-up period, we update our experience with conservative management of vestibular schwannomas. Study Design: Patients with intracanalicular and small/medium-sized tumors have been followed prospectively at a tertiary referral center. Methods: One hundred twenty-three patients affected by sporadic vestibular schwannoma were primarily observed by means of magnetic resonance imaging scans. In case of significant tumor growth (,2 mm), patients were either surgically treated or submitted to radiotherapy, but, not rarely, they continued to follow the "wait-and-scan" policy. Tumor-size changes over time were also evaluated with hearing function. Statistical analysis with predictive growth factors was performed. Results: Almost two thirds (64.5%) of the cases did not show tumor growth during the entire period of observation (mean follow-up period, 4.8 yrs). Among growing tumors, 16 patients were surgically treated with no complications or facial nerve palsy. Less than half (45.5%) of the patients presented useful hearing (classes A and B of the American Academy of Otolaryngology,Head and Neck Surgery classification) at diagnosis, and 41 (73.2%) patients had preserved hearing during follow-up independently from the tumor growth rate. Conclusions: Conservative management of vestibular schwannoma appears to be a safe procedure because most tumors do not grow and surgical outcomes are not affected by possible delays. In the great majority of cases, useful hearing is maintained over time. Because of the irregular behavior of the tumor, periodic neuroradiologic scans are mandatory to limit late surgical risks. [source] Combined Anterior-to-Posterior and Posterior-to-Anterior Approach to Paranasal Sinus Surgery: An Update,THE LARYNGOSCOPE, Issue 4 2006FACS, Steven D. Schaefer MD Abstract Objectives: To develop an anatomically and functionally based approach to endoscopic intranasal ethmoidectomy; to develop such an approach using the salient features of the anterior-to-posterior (AP) and posterior-to-anterior (PA) intranasal sinus operations; to assess the safety of this form of ethmoidectomy in a patient population. Study Design: Retrospective chart review of patients undergoing ethmoidectomy by the authors or by residents under their direct supervision. Setting: University teaching hospital. Results: Two thousand three hundred and forty-four patients underwent either unilateral or bilateral ethmoidectomies between April 1992 and August 2005. A complication rate of 0.34% was observed. Conclusions: Combining an AP approach to conserve sinus anatomy with a PA approach to avoid surgery directed toward the skull base provides a functional and safe procedure, as demonstrated by the reported results. [source] 2509 Living Donor Nephrectomies, Morbidity and Mortality, Including the UK Introduction of Laparoscopic Donor SurgeryAMERICAN JOURNAL OF TRANSPLANTATION, Issue 11 2007V. G. Hadjianastassiou The worldwide expansion of laparoscopic, at the expense of open, donor nephrectomy (DN) has been driven on the basis of faster convalescence for the donor. However, concerns have been expressed over the safety of the laparoscopic procedure. The UK Transplant National Registry collecting mandatory information on all living kidney donations in the country was analyzed for donations between November 2000 (start of living donor follow-up data reporting) to June 2006 to assess the safety of living DN, after the recent introduction of the laparoscopic procedure in the United Kingdom. Twenty-four transplant units reported data on 2509 donors (601 laparoscopic, 1800 open and 108 [4.3%] unspecified); 46.5% male; mean donor age: 46 years. There was one death 3 months postdischarge and a further five deaths beyond 1 year postdischarge. The mean length of stay was 1.5 days less for the laparoscopic procedure (p < 0.001). The risk of major morbidity for all donors was 4.9% (laparoscopic = 4.5%, open = 5.1%, p = 0.549). The overall rate of any morbidity was 14.3% (laparoscopic = 10.3%, open = 15.7%, p = 0.001). Living donation has remained a safe procedure in the UK during the learning curve of introduction of the laparoscopic procedure. The latter offers measurable advantages to the donor in terms of reduced length of stay and morbidity. [source] The actual incidence of papaverine-induced priapism in patients with erectile dysfunction following penile colour Doppler ultrasonographyANDROLOGIA, Issue 1 2010M. Kilic Summary Penile color Doppler sonography is a valuable method for evaluating erectile dysfunction. However, there are some concerns about the safety of this method due to the intracorporeal pharmacological injection, which may cause priapism as a complication, resulting in penile fibrosis. To evaluate the actual incidence of papaverine-induced priapism in patients with erectile dysfunction (ED) who underwent penile colour Doppler sonography and to determine the safety of this diagnostic tool, a retrospective study was conducted using the database of our institution. A total of 672 men with ED underwent penile color Doppler ultrasonography with the intracorporeal injection of 60 mg papaverine hydrochloride. The patient characteristics of priapism cases were retrospectively evaluated. Priapism in 18 of the 672 patients (2.68%) was successfully treated with blood aspiration, irrigation and injection of an ,-agonist medication, when needed. Patients with priapism were younger compared with those without priapism; mean age 45 ± 12.51 (20,68) versus 50.93 ± 12.04 (17,78) (P < 0.001). Penile Doppler ultrasound is a safe procedure in evaluating erectile dysfunction. The incidence of priapism, which is the most important complication of this procedure, is low and can be managed successfully with conservative approaches. [source] Pancreaticoduodenectomy , outcomes from an Australian institutionANZ JOURNAL OF SURGERY, Issue 9 2010Kelvin H.K. Kwok Abstract Background:, Operative morbidity and mortality rates have improved markedly since the first single-stage pancreaticoduodenectomy (PD) was performed by A. O. Whipple in 1940. There is a lack of published data regarding outcomes of PD from Australian centres. The aim of this study was primarily to establish post-operative morbidity and mortality rates of an Australian unit, and secondly, to investigate the value of preoperative investigation with endoscopic ultrasound and laparoscopy upon tumour stage and survival following PD. Method:, A retrospective analysis was conducted on consecutive patients undergoing PD at St Vincent's Hospital from 1990 to 2006. Data were collected with particular reference to preoperative investigations, including endoscopic ultrasonography (EUS) and staging laparoscopy, and post-operative complications. Patient survival was determined from the hospital and consultant surgeons' records and telephone interviews with the patients' general practitioners. Results:, Eighty-one patients underwent PD, of which 58 were Whipple's procedures and 23 were pylorus-preserving pancreaticoduodenectomies (PPPD). Twenty-six patients had EUS, and 22 had a staging laparoscopy before PD. The post-operative morbidity rate was 55% and included intra-abdominal collections (17%), major haemorrhage (10.7%), pancreatic anastomotic leakage (9%) and delayed gastric emptying (22%). The operative (30-day) mortality rate was 1.6%. There was no survival advantage in the EUS or the laparoscopy group. Conclusion:, EUS and laparoscopy are useful modalities in the preoperative investigation and staging of patients being considered for PD. PD is a safe procedure with acceptable complication rates when carried out in a specialist unit experienced in this operation. [source] Outcomes of minimally invasive surgery for phaeochromocytomaANZ JOURNAL OF SURGERY, Issue 5 2009Goswin Y. Meyer-Rochow Laparoscopic adrenalectomy is now accepted as the procedure of choice for the resection of benign adrenocortical tumours, but few studies have assessed whether the outcomes of laparoscopic adrenalectomy for adrenal phaeochromocytoma are similar to that of other adrenal tumour types. This is a retrospective cohort study. Clinical and operative data were obtained from an adrenal tumour database and hospital records. A total of 191 patients had laparoscopic adrenalectomy, of which 36 were for phaeochromocytoma, over a 12-year period. Length of hospital stay (4.8 vs 3.6 days, P= 0.03) and total operating times (183 vs 157 min, P= 0.01) were greater in the laparoscopic phaeochromocytoma resection group. Despite the greater size of the phaeochromocytomas compared to the remaining adrenal tumour types (44 mm vs 30 mm, P < 0.01), however, rate of conversion and morbidity were no different. Laparoscopic adrenalectomy for phaeochromocytoma is a safe procedure with similar outcomes to laparoscopic adrenalectomy for other adrenal tumour types. [source] Reoperative adrenal surgery: lessons learntANZ JOURNAL OF SURGERY, Issue 5 2009Charles T. Tan With the widespread use of abdominal imaging, the detection and therefore incidence of adrenal tumours is increasing. The laparoscopic approach to primary surgical resection of adrenal tumours has now become the standard of care. There is scarce published literature regarding the management and outcomes of recurrent adrenal tumours. The aim of the present study was therefore to review the authors' experience with reoperative adrenal surgery. A retrospective review of reoperative adrenalectomy cases identified from the prospectively maintained University of Sydney Endocrine Surgical Unit Database from January 1988 to July 2007 was carried out. There were nine (3.5%) reoperative adrenalectomies in six patients. Two were cases of adrenocortical carcinoma, two involved cases of familial phaeochromocytomas and two cases were due to sporadic phaeochromocytomas. Reoperative adrenal surgery is an uncommon event. During the index surgery for adrenal tumours, all adrenal tissue should be removed and knowledge of the vagaries of adrenal anatomy is essential. Reoperative adrenal surgery is a safe procedure and may confer survival benefit or symptom relief. Lifelong follow up is essential for all patients who have had surgery for functional and malignant adrenal tumours. [source] LONG-TERM OUTCOMES AFTER LAPAROSCOPIC BILE DUCT EXPLORATION: A 5-YEAR FOLLOW UP OF 150 CONSECUTIVE PATIENTSANZ JOURNAL OF SURGERY, Issue 6 2008Andrew J. M. Campbell-Lloyd Background: The treatment of common bile duct stones discovered at routine intraoperative cholangiography includes postoperative endoscopic retrograde cholangiography or intraoperative laparoscopic common bile duct exploration. Given the equivalence of short-term outcome data for these two techniques, the choice of one over the other may be influenced by long-term follow-up data. We aimed to establish the long-term outcomes following laparoscopic common bile duct exploration and compare this with endoscopic retrograde cholangiography. Methods: One hundred and fifty consecutive patients underwent laparoscopic common bile duct exploration between March 1998 and March 2006 carried out by a single surgeon. All were prospectively studied for 1 month followed by a late-term phone questionnaire ascertaining the prevalence of adverse symptoms. Patients presented with a standardized series of questions, with reports of symptoms corroborated by review of medical records. Results: In 150 patients, operations included laparoscopic transcystic exploration (135), choledochotomy (10) and choledochoduodenostomy (2). At long-term follow up (mean 63 months), 116 (77.3%) patients were traceable, with 24 (20.7%) reporting an episode of pain and 18 (15.5%) had more than a single episode of pain. There was no long-term evidence of cholangitis, stricture or pancreatitis identified in any patient. Conclusion: Laparoscopic bile duct exploration appears not to increase the incidence of long-term adverse sequelae beyond the reported prevalence of postcholecystectomy symptoms. There was no incidence of bile duct stricture, cholangitis or pancreatitis. It is a safe procedure, which obviates the need and expense of preoperative or postoperative endoscopic retrograde cholangiography in most instances. [source] Musculoskeletal tissue banking in Western Australia: review of the first ten yearsANZ JOURNAL OF SURGERY, Issue 8 2005Joyleen M. Winter Background: Musculoskeletal tissue allotransplantation has been used as a standard approach for reconstructive surgery. The present study has reviewed the banking of musculoskeletal tissue at the Perth Bone and Tissue Bank (PBTB) and provided evidence of quality assurance on musculoskeletal tissue allotransplantation. Methods: All donor tissues were processed in accordance with the Therapeutic Goods Administration's relevant codes of good manufacturing practices. Microbiological monitoring at each step of manufacture and postoperative surveying of the musculoskeletal allotransplantations were both conducted. The possible contribution of contaminants in allografts to postoperative infections was also assessed. Results: Of the 5276 donors obtained over the last 10 years, 1672 were rejected, giving an overall donor rejection rate of 32%. Milled femoral heads were the most frequently implanted allografts, followed by whole femoral heads. In the postoperative survey an infection rate of 4.9% was found (113/2321 recipients). The infectious agents were identified in 65 cases but for 60 of these there were no correlations with the positive culture test results for the allografts. The organism most commonly identified in postoperative infections was Staphylococcus species. Conclusions: The present study shows evidence that musculoskeletal tissue allotransplantation is a safe procedure when accompanied by high standards of quality assurance.
