MRgFUS may provide a safe and effective noninvasive alternative for the palliation of pain, caused by bone metastases.

Resection yields superior results, yet the majority of surgeons ablate, probably because it is easier, requires a shorter operating time, leads to fewer cases of Horner's syndrome, and because resympathectomy eventually overcomes initial failure.

Introduction The Accreditation and Certification of Hernia Centers and Surgeons (ACCESS) Group of the European Hernia Society (EHS) recognizes that there is a growing need to train specialist abdominal wall surgeons. The most important and relevant argument for this proposal and statement is the growing acceptance of the increasing complexity of abdominal wall surgery due to newer techniques, more challenging cases and the required 'tailored' approach to such surgery. There is now also an increasing public awareness with social media, whereby optimal treatment results are demanded by patients. However, to date the complexity of abdominal wall surgery has not been properly or adequately defined in the current literature. Methods A systematic search of the available literature was performed in May 2019 using Medline, PubMed, Scopus, Embase, Springer Link, and the Cochrane Library, with 75 publications identified as relevant. In addition, an analysis of data from the Herniamed Hernia Registry was performed. The percentage of patients with hernia-or patient-related characteristics which unfavorably impacted the outcome of inguinal and incisional hernia repair was also calculated. Results All present guidelines for abdominal wall surgery recommend the utilization of a 'tailored' approach. This relies on the prerequisite that any surgical technique used has already been mastered, as well as the recognized learning curves for each of the several techniques that can be used for both inguinal hernia (Lichtenstein, TEP, TAPP, Shouldice) and incisional hernia repairs (laparoscopic IPOM, open sublay, open IPOM, open onlay, open or endoscopic component separation technique).Other hernia-and patient-related characteristics that have recognized complexity include emergency surgery, obesity, recurrent hernias, bilateral inguinal hernias, groin hernia in women, scrotal hernias, large defects, high ASA scores, > 80 years of age, increased medical risk factors and previous lower abdominal surgery. The proportion of patients with at least one of these characteristics in the Herniamed Hernia Registry in the case of both inguinal and incisional hernia is noted to be relatively high at around 70%. In general surgery training approximately 50-100 hernia repairs on average are performed by each trainee, with around only 25 laparo-endoscopic procedures. Conclusion A tailored approach is now employed and seen more so in hernia surgery and this fact is referred to and highlighted in the contemporaneous hernia guidelines published to date. In addition, with the increasing complexity of abdominal wall surgery, the number of procedures actually performed by trainees is no longer considered adequate to overcome any recognized learning curve. Therefore, to supplement general surgery training young surgeons should be offered a clinical fellowship to obtain an additional qualification as an abdominal wall surgeon and thus improve their clinical and operative experience under supervision in this field. Practicing general surgeons with a special int...

Primary palmar hyperhidrosis (HH) is a pathological condition of overperspiration caused by excessive secretion of the eccrine sweat glands, the etiology of which is unknown. This disorder affects a small but significant proportion of the young population all over the world. Neither systemic nor topical drugs have been found to satisfactorily alleviate the symptoms. Although the topical injection of botulinum has recently been reported to reduce the amount of local perspiration, long-term results are required before a definitive evaluation of this method can be made. Hypnosis, psychotherapy, and biofeedback have been beneficial in a limited-number of cases. While radiation achieves atrophy of the sweat glands, its detrimental effects prohibit its use. Iontophoresis has attained some satisfactory results but it has not been assessed long term. Percutaneous computed tomography-guided phenol sympathicolysis achieves excellent immediate results, but its long-term failure rate is prohibitive. Furthermore, percutaneous radiofrequency sympathicolysis may be an effective procedure, but its long-term results are not superior to surgical sympathectomy. On the other hand, surgical upper dorsal (T2-T3) sympathectomy achieves excellent long-term results and the thoracoscopic approach has supplanted the open procedures. Despite some sequelae, mainly in the form of neuralgia and compensatory sweating which cannot be predicted and may be distressing, surgical sympathectomy remains the best treatment for palmar hyperhidrosis.

Objective-Endothelial dysfunction and vascular dysregulation contribute to the pathological effects of radiation on tissues. The objectives of this study were to assess the acute effect of irradiation on acetylcholine (Ach)-induced dilation of gut submucosal microvessels. Methods and Results-Rats were exposed in vivo to 1 to 9 cGy in 3 fractions per week on alternate days for 3 successive weeks for a total dose of up to 2250 cGy. Submucosal microvessels were isolated after varying levels of irradiation. Diameters of isolated vessels were measured using videomicroscopy, and the dose-response relationship to Ach was determined. Dihydroethidine and 2Ј, 7Ј-dichlorodihydrofluorescein diacetate fluorescent probes were used to assess reactive oxygen species (ROS) production. After constriction (30% to 50%) with endothelin, dilation to graded doses of Ach (10 Ϫ9 Ϫ10 Ϫ4 M) was observed in control vessels (maximal dilation [MD] 87Ϯ3%; nϭ7). However, Ach-induced dilation was reduced in vessels from irradiated rats (MDϭ3Ϯ9%; nϭ7; PϭϽ0.05 versus controls). Significant increases in superoxide and peroxides were observed in irradiated microvessels. Irradiated microvessels pretreated with superoxide dismutase-mimetic demonstrated significant improvement in Ach-induced vasodilation compared with irradiation alone, suggesting that superoxide contributes to impaired dilation to Ach after irradiation. Conclusions-Radiation

The potential of an in situ gel-forming adhesive was examined as a hemostatic surgical sealant. The gel-forming mechanism for this adhesive mimics the last stages of blood coagulation but uses nonblood proteins. Specifically, gelatin is used as the structural protein and a calcium-independent microbial transglutaminase (mTG) is used as the crosslinking enzyme. In vitro burst pressure tests with porcine skin demonstrate that the gelatin-mTG adhesive forms a gel within 30 min under moist conditions and this gel can restrain pressures of 200 mmHg. In vivo tests with a rat liver wound model showed that the gelatin-mTG adhesive achieves complete hemostasis in 2.5 min and the gel (i.e., the biomimetic clot) offers substantial adhesive and cohesive strength. Complete hemostasis was also observed in 2.5 min after the gelatin-mTG adhesive was applied to a briskly bleeding rat femoral artery wound. In a large animal porcine model, a femoral artery wound that resulted in extensive bleeding was sealed in 4 min by (i) clamping the artery for temporary hemostasis, (ii) removing excess blood, and (iii) applying the gelatin-mTG adhesive. Thus, the biomimetic gelatin-mTG adhesive may provide a simple, safe, and cost-effective surgical sealant.

Despite the large number of postoperative long-term sequelae, 88.5% of patients expressed subjective satisfaction from the procedure. Obtaining 100% of dry hands on mid-term follow-up makes this approach rewarding.
