- Acute appendicitis (AA) is among the most common cause of acute abdominal pain. Diagnosis of AA is challenging; a variable combination of clinical signs and symptoms has been used together with laboratory findings in several scoring systems proposed for suggesting the probability of AA and the possible subsequent management pathway. The role of imaging in the diagnosis of AA is still debated, with variable use of US, CT and MRI in different settings worldwide. Up to date, comprehensive clinical guidelines for diagnosis and management of AA have never been issued. In July 2015, during the 3rd World Congress of the WSES, held in Jerusalem (Israel), a panel of experts including an Organizational Committee and Scientific Committee and Scientific Secretariat, participated to a Consensus Conference where eight panelists presented a number of statements developed for each of the eight main questions about diagnosis and management of AA. The statements were then voted, eventually modified and finally approved by the participants to The Consensus Conference and lately by the board of co-authors. The current paper is reporting the definitive Guidelines Statements on each of the following topics: 1) Diagnostic efficiency of clinical scoring systems, 2) Role of Imaging, 3) Non-operative treatment for uncomplicated appendicitis, 4) Timing of appendectomy and in-hospital delay, 5) Surgical treatment 6) Scoring systems for intra-operative grading of appendicitis and their clinical usefulness 7) Non-surgical treatment for complicated appendicitis: abscess or phlegmon 8) Pre-operative and post-operative antibiotics.

- Copy number variation of the C4 complement components, C4A and C4B, has been associated with systemic inflammatory autoimmune diseases. We asked if C4 copy number variation is connected to the autoimmune repertoire in systemic lupus erythematosus (SLE), primary Sjögren's syndrome (pSS) or myositis.Using targeted DNA sequencing, we determined the copy number and genetic variants of C4 in 2,290 well-characterised Scandinavian patients with SLE, pSS or myositis, and 1,251 healthy controls.A prominent relationship was observed between C4A copy number and the presence of SSA/SSB autoantibodies, which was shared between the three diseases. The strongest association was detected for patients with autoantibodies against both SSA and SSB and 0 C4A copies when compared to healthy controls (OR=18.0; CI95% : 10.2-33.3), whereas a weaker association was seen for patients without SSA/SSB autoantibodies (OR=3.1; CI95% : 1.7-5.5). The copy number of C4 correlated positively with C4 plasma levels. Further, a common loss-of-function variant in C4A leading to reduced plasma C4 was more prevalent in SLE patients with a low copy number of C4A. Functionally, we showed that absence of C4A reduced the individuals' capacity to deposit C4b on immune complexes.We show that a low C4A copy number more strongly is associated with the autoantibody repertoire than with the clinically defined disease entities. These results may have implication for understanding the aetiopathogenetic mechanisms of systemic inflammatory autoimmune diseases, and for patient stratification when taking the genetic profile into account.

Ingår i: Acta Oncologica. - 0284-186X .- 1651-226X. ; 49:4, s. 454-459

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: There is still no complete agreement about the proper treatment of differentiated thyroid cancer (DTC). MATERIAL AND METHODS: All patients (n=130) with DTC in a defined population, treated with surgery between 1985 and 1999, were carefully followed up (median 13.1 years). Fifty three were operated with subtotal and 77 with total thyroidectomy. Twenty seven percent of the patients in the subtotal group and 56% of those in the total thyroidectomy group had postoperative radioiodine ablation. Thirty nine patients had papillary cancers incidentally detected during surgery for benign disorders (median size 7 (1-30) mm). Living patients answered the Swedish version of the SF-36 health survey. RESULTS: Eleven of 106 patients considered tumour-free after primary surgery developed recurrences during follow-up. Fifteen patients (12%) died from DTC but only one within stage I-II (1.2%). No patient below 50 years of age at diagnosis died from DTC. Only three of 29 patients with isolated loco-regional spreading of their disease at the time of diagnosis have died from thyroid cancer. There was no statistically significant difference in the 10 year cancer-specific survival rate between those operated with subtotal or total thyroidectomy--irrespective of stage. Survival rate was significantly better for papillary than for follicular cancer. Mental and physical quality of life among patients treated for DTC were similar to the healthy Swedish population. CONCLUSIONS: Patients with DTC stage I-II (according to TNM) or low-risk (according to AMES) have an excellent prognosis. Treatment as well as follow-up should not be exaggerated.

Dysregulated Th1/Th17 response in advanced appendicitis
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: The pathogenesis of appendicitis, the most common abdominal emergency for surgical intervention, is still unknown. Epidemiological differences between perforated and nonperforated appendicitis, polymorphism in the interleukin (IL)-6 gene associated with severity of appendicitis and a more pronounced Th1/Th17-like deviation in advanced compared to phlegmonous appendicitis has been reported. Altogether these findings may indicate that appendicitis harbours two different entities with different immuno-pathogenesis, one progressing to gangrene and perforation and one resolving. In this study we aimed to further investigate systemic cytokine profiles in a large sample of patients, with advanced and phlegmonous appendicitis from a Th1, Th2, Th17 and innate perspective, and also clarify if time as duration of symptoms could explain the differences.Methods: Blood samples were preoperatively collected from patients with advanced (n=61) and phlegmonous appendicitis (n=108). The Th1-associated (IFN-γ, IL-12p70), Th2-associated (IL-4, IL-5), Th17-associated (IL-17, IL-6, CCL20, CCL2) and innate-associated (IL-1β, IL-6, MPO, CXCL8, GM-CSF), markers were analyzed in plasma using multiplex bead assay.Results: Patients with advanced appendicitis had increased levels of IL-6 (P=0.0001), CCL2 (P=0.001), MPO (P=0.039), IL-12p70 (P=0.010) and CCL20 (P=0.002) as compared to phlegmonous appendicitis and age, sex or duration of symptoms at sampling could not explain the differences.Conclusion: The findings suggest a dysregulated Th1/Th17 type inflammation in advanced appendicitis, already early in the disease course, that eventuates in gangrene and perforation and gives further support to the notion of appendicitis as two entities.

- Objective To analyze associations of maternal, fetal, gestational, and perinatal factors with necrotizing enterocolitis in a matched case-control study based on routinely collected, nationwide register data. Study design All infants born in 1987 through 2009 with a diagnosis of necrotizing enterocolitis in any of the Swedish national health care registers were identified. For each case up to 6 controls, matched for birth year and gestational age, were selected. The resulting study population consisted of 720 cases and 3,567 controls. Information on socioeconomic data about the mother, maternal morbidity, pregnancy related diagnoses, perinatal diagnoses of the infant, and procedures in the perinatal period, was obtained for all cases and controls and analyzed with univariable and multivariable logistic regressions for the whole study population as well as for subgroups according to gestational age. Results In the study population as a whole, we found independent positive associations with necrotizing enterocolitis for isoimmunization, fetal distress, cesarean section, neonatal bacterial infection including sepsis, erythrocyte transfusion, persistent ductus arteriosus, cardiac malformation, gastrointestinal malformation, and chromosomal abnormality. Negative associations were found for maternal weight, preeclampsia, maternal urinary infection, premature rupture of the membranes, and birthweight. Different patterns of associations were seen in the subgroups of different gestational age. Conclusion With some interesting exceptions, especially in negative associations, the results of this large, population based study, are in keeping with earlier studies. Although restrained by the limitations of register data, the findings mirror conceivable pathophysiological processes and underline that NEC is a multifactorial disease. © 2018 Ahle et al.

- Nonsurgical treatment with antibiotics has recently been proposed as the first line of treatment for noncomplicated appendicitis. This has met with considerable interest, illustrated by the number of reviews and meta-analyses, which exceed the number of original reports of the issue. The results in these studies are seriously biased due to inclusion of patients with resolving appendicitis. At a time when we need to reduce inappropriate use of antibiotics in the struggle against the increasing rate of antibiotics resistance, there must be strong requirements of a proven effect and an improved cost-benefit ratio before antibiotics treatment is introduced for a new group of patients. These requirements have not yet been met for nonsurgical treatment with antibiotics for assumed uncomplicated appendicitis. Due to the high rate of spontaneous resolution, a randomized placebo-controlled trial is needed that can compare the efficiency of antibiotics treatment and expectant management in this group of patients. Antibiotics treatment, however, remains indicated for treatment of perforated appendicitis with localized abscess or phlegmone and in selected surgical high-risk patients.

- Background: Obstructive left colon carcinoma (OLCC) is a challenging matter in terms of obstruction release as well of oncological issues. Several options are available and no guidelines are established. The paper aims to generate evidenced based recommendations on management of OLCC. Methods: The PubMed and Cochrane Library databases were queried for publications focusing on OLCC published prior to April 2010. A extensive retrieval, analyses, and grading of the literature was undertaken. The findings of the research were presented and largely discussed among panellist and audience at the Consensus Conference of the World Society of Emergency Surgery (WSES) and Peritoneum and Surgery (PnS) Society held in Bologna July 2010. Comparisons of techniques are presented and final committee recommendation are enounced. Results: Hartmann's procedure should be preferred to loop colostomy (Grade 2B). Hartmann's procedure offers no survival benefit compared to segmental colonic resection with primary anastomosis (Grade 2C+); Hartmann's procedure should be considered in patients with high surgical risk (Grade 2C). Total colectomy and segmental colectomy with intraoperative colonic irrigation are associated with same mortality/morbidity, however total colectomy is associated with higher rates impaired bowel function (Grade 1A). Segmental resection and primary anastomosis either with manual decompression or intraoperative colonic irrigation are associated with same mortality/morbidity rate (Grade 1A). In palliation stent placement is associated with similar mortality/morbidity rates and shorter hospital stay (Grade 2B). Stents as a bridge to surgery seems associated with lower mortality rate, shorter hospital stay, and a lower colostomy formation rate (Grade 1B). Conclusions: Loop colostomy and staged procedure should be adopted in case of dramatic scenario, when neoadjuvant therapy could be expected. Hartmann's procedure should be performed in case of high risk of anastomotic dehiscence. Subtotal and total colectomy should be attempted when cecal perforation or in case of synchronous colonic neoplasm. Primary resection and anastomosis with manual decompression seems the procedure of choice. Colonic stents represent the best option when skills are available. The literature power is relatively poor and the existing RCT are often not sufficiently robust in design thus, among 6 possible treatment modalities, only 2 reached the Grade A.

- Background and aims Acute appendicitis (AA) is among the most common causes of acute abdominal pain. Diagnosis of AA is still challenging and some controversies on its management are still present among different settings and practice patterns worldwide. In July 2015, the World Society of Emergency Surgery (WSES) organized in Jerusalem the first consensus conference on the diagnosis and treatment of AA in adult patients with the intention of producing evidence-based guidelines. An updated consensus conference took place in Nijemegen in June 2019 and the guidelines have now been updated in order to provide evidence-based statements and recommendations in keeping with varying clinical practice: use of clinical scores and imaging in diagnosing AA, indications and timing for surgery, use of non-operative management and antibiotics, laparoscopy and surgical techniques, intra-operative scoring, and peri-operative antibiotic therapy. Methods This executive manuscript summarizes the WSES guidelines for the diagnosis and treatment of AA. Literature search has been updated up to 2019 and statements and recommendations have been developed according to the GRADE methodology. The statements were voted, eventually modified, and finally approved by the participants to the consensus conference and by the board of co-authors, using a Delphi methodology for voting whenever there was controversy on a statement or a recommendation. Several tables highlighting the research topics and questions, search syntaxes, and the statements and the WSES evidence-based recommendations are provided. Finally, two different practical clinical algorithms are provided in the form of a flow chart for both adults and pediatric (< 16 years old) patients. Conclusions The 2020 WSES guidelines on AA aim to provide updated evidence-based statements and recommendations on each of the following topics: (1) diagnosis, (2) non-operative management for uncomplicated AA, (3) timing of appendectomy and in-hospital delay, (4) surgical treatment, (5) intra-operative grading of AA, (6) ,management of perforated AA with phlegmon or abscess, and (7) peri-operative antibiotic therapy.
