Review
INTRODUCTION
The definition of severe recurrent throat infections is arbitrary, but recent criteria have defined severe tonsillitis as: five or more episodes of true tonsillitis a year; symptoms for at least 1 year; and episodes that are disabling and prevent normal functioning. Diagnosis of acute tonsillitis is clinical, and it can be difficult to distinguish viral from bacterial infections. Rapid antigen testing has a very low sensitivity in the diagnosis of bacterial tonsillitis, but more accurate tests take longer to deliver results. Bacteria are cultured from few people with tonsillitis. Other causes include infectious mononucleosis from Epstein-Barr virus infection, cytomegalovirus, toxoplasmosis, HIV, hepatitis A, and rubella.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of tonsillectomy in children and adults with acute recurrent or chronic throat infections? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 15 studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review, we present information relating to the effectiveness and safety of the following interventions: cold-steel tonsillectomy and diathermy tonsillectomy.

Review
BACKGROUND
The integrity of healthy skin plays a crucial role in maintaining physiological homeostasis of the human body. The skin is the largest organ system of the body. As such, it plays pivotal roles in the protection against mechanical forces and infections, fluid imbalance, and thermal dysregulation. At the same time, it allows for flexibility to enable joint function in some areas of the body and more rigid fixation to hinder shifting of the palm or foot sole. Many instances lead to inadequate wound healing which necessitates medical intervention. Chronic conditions such as diabetes mellitus or peripheral vascular disease can lead to impaired wound healing. Acute trauma such as degloving or large-scale thermal injuries are followed by a loss of skin organ function rendering the organism vulnerable to infections, thermal dysregulation, and fluid loss.
METHODS
For this update article, we have reviewed the actual literature on skin wound healing purposes focusing on the main phases of wound healing, i.e., inflammation, proliferation, epithelialization, angiogenesis, remodeling, and scarring.
RESULTS
The reader will get briefed on new insights and up-to-date concepts in skin wound healing. The macrophage as a key player in the inflammatory phase will be highlighted. During the epithelialization process, we will present the different concepts of how the wound will get closed, e.g., leapfrogging, lamellipodial crawling, shuffling, and the stem cell niche. The neovascularization represents an essential component in wound healing due to its fundamental impact from the very beginning after skin injury until the end of the wound remodeling. Here, the distinct pattern of the neovascularization process and the special new functions of the pericyte will be underscored. At the end, this update will present 3 topics of high interest in skin wound healing issues, dealing with scarring, tissue engineering, and plasma application.
CONCLUSION
Although wound healing mechanisms and specific cell functions in wound repair have been delineated in part, many underlying pathophysiological processes are still unknown. The purpose of the following update on skin wound healing is to focus on the different phases and to brief the reader on the current knowledge and new insights. Skin wound healing is a complex process, which is dependent on many cell types and mediators interacting in a highly sophisticated temporal sequence. Although some interactions during the healing process are crucial, redundancy is high and other cells or mediators can adopt functions or signaling without major complications.

Meta-Analysis
BACKGROUND
Endometriosis is associated with pain and infertility. Surgical interventions aim to remove visible areas of endometriosis and restore the anatomy.
OBJECTIVES
To assess the effectiveness and safety of laparoscopic surgery in the treatment of pain and infertility associated with endometriosis.
SEARCH METHODS
This review has drawn on the search strategy developed by the Cochrane Gynaecology and Fertility Group including searching the Cochrane Gynaecology and Fertility Group's specialised register, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, reference lists for relevant trials, and trial registries from inception to April 2020.
SELECTION CRITERIA
We selected randomised controlled trials (RCTs) that compared the effectiveness and safety of laparoscopic surgery with any other laparoscopic or robotic intervention, holistic or medical treatment, or diagnostic laparoscopy only.
DATA COLLECTION AND ANALYSIS
Two review authors independently performed selection of studies, assessment of trial quality and extraction of relevant data with disagreements resolved by a third review author. We collected data for the core outcome set for endometriosis. Primary outcomes included overall pain and live birth. We evaluated the quality of evidence using GRADE methods.
MAIN RESULTS
We included 14 RCTs. The studies randomised 1563 women with endometriosis. Four RCTs compared laparoscopic ablation or excision with diagnostic laparoscopy only. Two RCTs compared laparoscopic excision with diagnostic laparoscopy only. One RCT compared laparoscopic ablation or excision with laparoscopic ablation or excision and uterine suspension. Two RCTs compared laparoscopic ablation and uterine nerve transection with diagnostic laparoscopy only. One RCT compared laparoscopic ablation with diagnostic laparoscopy and gonadotropin-releasing hormone (GnRH) analogues. Two RCTs compared laparoscopic ablation with laparoscopic excision. One RCT compared laparoscopic ablation or excision with helium thermal coagulator with laparoscopic ablation or excision with electrodiathermy. One RCT compared conservative laparoscopic surgery with laparoscopic colorectal resection of deep endometriosis infiltrating the rectum. Common limitations in the primary studies included lack of clearly described blinding, failure to fully describe methods of randomisation and allocation concealment, and poor reporting of outcome data. Laparoscopic treatment versus diagnostic laparoscopy We are uncertain of the effect of laparoscopic treatment on overall pain scores compared to diagnostic laparoscopy only at six months (mean difference (MD) 0.90, 95% confidence interval (CI) 0.31 to 1.49; 1 RCT, 16 participants; very low quality evidence) and at 12 months (MD 1.65, 95% CI 1.11 to 2.19; 1 RCT, 16 participants; very low quality evidence), where a positive value means pain relief (the higher the score, the more pain relief) and a negative value reflects pain increase (the lower the score, the worse the increase in pain). No studies looked at live birth. We are uncertain of the effect of laparoscopic treatment on quality of life compared to diagnostic laparoscopy only: EuroQol-5D index summary at six months (MD 0.03, 95% CI -0.12 to 0.18; 1 RCT, 39 participants; low quality evidence), 12-item Short Form (SF-12) mental health component (MD 2.30, 95% CI -4.50 to 9.10; 1 RCT, 39 participants; low quality evidence) and SF-12 physical health component (MD 2.70, 95% CI -2.90 to 8.30; 1 RCT, 39 participants; low quality evidence). Laparoscopic treatment probably improves viable intrauterine pregnancy rate compared to diagnostic laparoscopy only (odds ratio (OR) 1.89, 95% CI 1.25 to 2.86; 3 RCTs, 528 participants; I = 0%; moderate quality evidence). We are uncertain of the effect of laparoscopic treatment compared to diagnostic laparoscopy only on ectopic pregnancy (MD 1.18, 95% CI 0.10 to 13.48; 1 RCT, 100 participants; low quality evidence) and miscarriage (MD 0.94, 95% CI 0.35 to 2.54; 2 RCTs, 112 participants; low quality evidence). There was limited reporting of adverse events. No conversions to laparotomy were reported in both groups (1 RCT, 341 participants). Laparoscopic ablation and uterine nerve transection versus diagnostic laparoscopy We are uncertain of the effect of laparoscopic ablation and uterine nerve transection on adverse events (more specifically vascular injury) compared to diagnostic laparoscopy only (OR 0.33, 95% CI 0.01 to 8.32; 1 RCT, 141 participants; low quality evidence). No studies looked at overall pain scores (at six and 12 months), live birth, quality of life, viable intrauterine pregnancy confirmed by ultrasound, ectopic pregnancy and miscarriage. Laparoscopic ablation versus laparoscopic excision There was insufficient evidence to determine whether there was a difference in overall pain, measured at 12 months, for laparoscopic ablation compared with laparoscopic excision (MD 0.00, 95% CI -1.22 to 1.22; 1 RCT, 103 participants; very low quality evidence). No studies looked at overall pain scores at six months, live birth, quality of life, viable intrauterine pregnancy confirmed by ultrasound, ectopic pregnancy, miscarriage and adverse events. Helium thermal coagulator versus electrodiathermy We are uncertain whether helium thermal coagulator compared to electrodiathermy improves quality of life using the 30-item Endometriosis Health Profile (EHP-30) at nine months, when considering the components: pain (MD 6.68, 95% CI -3.07 to 16.43; 1 RCT, 119 participants; very low quality evidence), control and powerlessness (MD 4.79, 95% CI -6.92 to 16.50; 1 RCT, 119 participants; very low quality evidence), emotional well-being (MD 6.17, 95% CI -3.95 to 16.29; 1 RCT, 119 participants; very low quality evidence) and social support (MD 5.62, 95% CI -6.21 to 17.45; 1 RCT, 119 participants; very low quality evidence). Adverse events were not estimable. No studies looked at overall pain scores (at six and 12 months), live birth, viable intrauterine pregnancy confirmed by ultrasound, ectopic pregnancy and miscarriage.
AUTHORS' CONCLUSIONS
Compared to diagnostic laparoscopy only, it is uncertain whether laparoscopic surgery reduces overall pain associated with minimal to severe endometriosis. No data were reported on live birth. There is moderate quality evidence that laparoscopic surgery increases viable intrauterine pregnancy rates confirmed by ultrasound compared to diagnostic laparoscopy only. No studies were found that looked at live birth for any of the comparisons. Further research is needed considering the management of different subtypes of endometriosis and comparing laparoscopic interventions with lifestyle and medical interventions. There was insufficient evidence on adverse events to allow any conclusions to be drawn regarding safety.

Review
Operating room fires are rare but devastating events. Guidelines are available for the prevention and management of surgical fires; however, these recommendations are based on expert opinion and case series. The three components of an operating room fire are present in virtually all surgical procedures: an oxidizer (oxygen, nitrous oxide), an ignition source (i.e., laser, "Bovie"), and a fuel. This review analyzes each fire ingredient to determine the optimal clinical strategy to reduce the risk of fire. Surgical checklists, team training, and the specific management of an operating room fire are also reviewed.

Review
Stereoelectroencephalography-guided radiofrequency-thermocoagulation (SEEG-guided RF-TC) consists of coupling SEEG investigation with RF-TC stereotactic lesioning directly through the recording electrodes. In this systematic review the surgical technique, indications, and outcomes are described. Maximum accuracy is reached when a frame-based procedure with a robotic assistance and a per-operative vascular X-ray imaging are performed. Monitoring of the lesioning procedure based on the impedance, a sharp modification of which indicates that the thermocoagulation has reached its maximum volume, allows the optimization of the lesion size. The first indication concerns patients in whom a SEEG is required to determine whether surgery is feasible and in whom resection is indeed possible. Even if surgery is performed owing to insufficient efficacy of SEEG-guided RF-TC, the procedure remains interesting owing to its high positive predictive value for good outcome after surgery. The second indication concerns patients in whom phase I non-invasive investigations have concluded to surgical contraindication and who may still undergo SEEG in a purely therapeutic perspective (small deep zones inaccessible to surgery and network nodes of large epileptic networks). Lastly, SEEG-guided RF-TC can be considered as a first-line treatment for periventricular nodular heterotopia (PNH). Independently of indication, the overall seizure-free rate is 23% and the responder rate is 58%. The best results are obtained for PNH (38% seizure-free and 81% responders), while the worst results have been reported for temporal lobe-epilepsy in a dedicated study. The overall complication rate is 2.5%. More evidence is needed to help determine the exact place of SEEG-guided RF-TC in the surgical management algorithm.

BACKGROUND
Primary liver tumours and liver metastases from colorectal carcinoma are two of the most common malignant tumours to affect the liver. The liver is second only to the lymph nodes as the most common site for metastatic disease. More than half of the people with metastatic liver disease will die from metastatic complications. Electrocoagulation by diathermy is a method used to destroy tumour tissue, using a high-frequency electric current generating high temperatures, applied locally with an electrode (needle, blade, or ball). The objective of this method is to destroy the tumour completely, if possible, in a single session. With the time, electrocoagulation by diathermy has been replaced by other techniques, but the evidence is unclear.
OBJECTIVES
To assess the beneficial and harmful effects of electrocoagulation by diathermy, administered alone or with another intervention, versus no intervention, other ablation methods, or systemic treatments in people with liver metastases.
SEARCH METHODS
We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, MEDLINE Ovid, Embase Ovid, LILACS, Science Citation Index Expanded, Conference Proceedings Citation Index - Science, CINAHL, ClinicalTrials.gov, ICTRP, and FDA to October 2020.
SELECTION CRITERIA
We considered all randomised trials that assessed beneficial and harmful effects of electrocoagulation by diathermy, administered alone or with another intervention, versus comparators, in people with liver metastases, regardless of the location of the primary tumour.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. We assessed risk of bias of the included trial using predefined risk of bias domains, and presented the review results incorporating the certainty of the evidence using GRADE.
MAIN RESULTS
We included one randomised clinical trial with 306 participants (175 males; 131 females) who had undergone resection of the sigmoid colon, and who had five or more visible and palpable hepatic metastases. The diagnosis was confirmed by histological assessment (biopsy) and by carcinoembryonic antigen (CEA) level. The trial was conducted in Iraq. The age of participants ranged between 38 and 79 years. The participants were randomised to four different study groups. The liver metastases were biopsied and treated (only once) in three of the groups: 75 received electrocoagulation by diathermy alone, 76 received electrocoagulation plus allopurinol, 78 received electrocoagulation plus dimethyl sulphoxide. In the fourth intervention group, 77 participants functioning as controls received a vehicle solution of allopurinol 5 mL 4 x a day by mouth; the metastases were left untouched. The status of the liver and lungs was followed by ultrasound investigations, without the use of a contrast agent. Participants were followed for five years. The analyses are based on per-protocol data only analysing 223 participants. We judged the trial to be at high risk of bias. After excluding 'nonevaluable patients', the groups seemed comparable for baseline characteristics. Mortality due to disease spread at five-year follow-up was 98% in the electrocoagulation group (57/58 evaluable people); 87% in the electrocoagulation plus allopurinol group (46/53 evaluable people); 86% in the electrocoagulation plus dimethyl sulphoxide group (49/57 evaluable people); and 100% in the control group (55/55 evaluable people). We observed no difference in mortality between the electrocoagulation alone group versus the control group (risk ratio (RR) 0.98, 95% confidence interval (CI) 0.94 to 1.03; 113 participants; very low-certainty evidence). We observed lower mortality in the electrocoagulation combined with allopurinol or dimethyl sulphoxide group versus the control group (RR 0.87, 95% CI 0.80 to 0.95; 165 participants; low-certainty evidence). We are very uncertain regarding post-operative deaths between the electrocoagulation alone group versus the control group (RR 1.03, 95% CI 0.07 to 16.12; 152 participants; very low-certainty evidence) and between the electrocoagulation combined with allopurinol or dimethyl sulphoxide groups versus the control group (RR 1.00, 95% CI 0.09 to 10.86; 231 participants; very low-certainty evidence). The trial authors did not report data on number of participants with other adverse events and complications, recurrence of liver metastases, time to progression of liver metastases, tumour response measures, and health-related quality of life. Data on failure to clear liver metastases were not provided for the control group. There was no information on funding or conflict of interest. We identified no ongoing trials.
AUTHORS' CONCLUSIONS
The evidence on the beneficial and harmful effects of electrocoagulation alone or in combination with allopurinol or dimethyl sulphoxide in people with liver metastases is insufficient, as it is based on one randomised clinical trial at low to very low certainty. It is very uncertain if there is a difference in all-cause mortality and post-operative mortality between electrocoagulation alone versus control. It is also uncertain if electrocoagulation in combination with allopurinol or dimethyl sulphoxide may result in a slight reduction of all-cause mortality in comparison with a vehicle solution of allopurinol (control). It is very uncertain if there is a difference in post-operative mortality between the electrocoagulation combined with allopurinol or dimethyl sulphoxide group versus control. Data on other adverse events and complications, failure to clear liver metastases or recurrence of liver metastases, time to progression of liver metastases, tumour response measures, and health-related quality of life were most lacking or insufficiently reported for analysis. Electrocoagulation by diathermy is no longer used in the described way, and this may explain the lack of further trials.

Review
Epilepsy related to malformations of cortical development is frequently drug resistant or requires heavy medication, therefore surgery is key in their management. The role of stereotactic surgery has recently changed the diagnosis and treatment of focal cortical dysplasias (FCD), hypothalamic hamartomas (HH) and periventricular nodular heterotopias (PNH). In HH, radiosurgery using Gammaknife leads to 60 % of seizure control and is associated with excellent neuropsychological results without significant endocrine function impairment. The seizure control rate is even higher (more than 80 %) with monopolar multiple stereotactic thermocoagulations and Laser interstitial Thermal Therapy (LiTT). While the first technique is associated with a 2 % complications rate (but with excellent neuropsychological outcomes), the latest has up to 22 % side effects in some series. All three of these techniques have encouraging results, but controlled studies are still lacking to provide evidence-based new therapeutic algorithms. With regard to the PNH, surgical management has long been limited by the depth of the lesions and their close anatomical relations with the functional brain connectome. Stereotactic approaches required to perform a SEEG, to locate the part of the PNH responsible for the seizure onset, are later followed by a stereotactic lesioning procedure, therefore doubling the bleeding risk. That is why SEEG-guided radiofrequency-thermocoagulation (SEEG guided-RF-TC), which makes it possible to perform these two steps in a single procedure, was considered as a promising option. A recent meta-analysis confirmed this intuition and reported 38 % of seizure-free patients and 81 % of responders with only 0.3 % of complications, making this approach the first treatment line, followed by LiTT. Among the multiple advances in the FCD identification by non-invasive investigations, a new modality of per-operative diagnostic procedure, the three-dimensional electrocorticography may lead to simplify the preoperative investigation and enhance the accuracy of FCD delineation. Evidence is nevertheless still insufficient to validate this promising concept. Conventional surgical resection has also been concerned by significant conceptual advances during the past few years, in particular with the development of the hodotopic approach, initially in oncologic surgery. Associated with a better understanding of neuroplasticity in epilepsy and the setting up of functional mapping during SEEG or during awake surgery, the possibility of surgical resections grew up. A short-term perspective in this field, when surgical resection remains impossible, would be to target crucial nodes of the epileptic network, distinct from the core functional connectome.

Review
Weight regain after bariatric surgery is common and can be managed with surgical interventions or less morbid endoscopic techniques. These endoscopic approaches target structural postoperative changes that are associated with weight regain, most notably dilation of the gastrojejunal anastomosis aperture. Purse string suture placement, as well as argon plasma coagulation application to the anastomosis, may result in significant and durable weight loss. Furthermore, various endoscopic approaches may be used to safely and effectively manage other complications of bariatric surgery that may result in poor weight loss or weight regain after surgery, including fistula formation.

BACKGROUND
Corneal angiogenesis occurs as a sequel to an insult and it brings with it cells that mediate immunity as well as repair and aids in flushing toxins out. These vessels are formed in haste and leak lipid and cells, ultimately resulting in loss of transparency, lipid keratopathy and immunogenicity. So, they may need treatment prior to an optical keratoplasty.
PURPOSE
To demonstrate the procedure of Fine Needle Diathermy (FND) to treat corneal neovascularization, its indications and contraindications.
SYNOPSIS
FND uses coagulating current from a monopolar cautery unit to occlude the afferent and efferent blood vessels. FND works best at the stage of mature vessel formation. The needle is placed across a tuft of vessels or parallel to a single large vessel, being mindful of the depth and direction. FND is avoided in necrotic tissue where the blood vessel is needed for healing process. Occlusion of the vessel in these situations may result in tissue melt.
HIGHLIGHTS
Corneal neovascularization follows the stages of latent phase, active neovascularization, mature vessel formation and then regression. The treatment modality depends on the stage of angiogenesis. FND works best for neovascularization due to infectious keratitis. Keratoplasty is best performed 3 to 4 months later when regression of corneal vascularization occurs.
