- BACKGROUND: Approximately half of trauma patients develop post-traumatic depression. It is suggested that beta-blockade impairs trauma memory recollection, reducing depressive symptoms. This study investigates the effect of early beta-blockade on depression following severe traumatic injuries in patients without significant brain injury.METHODS: Patients were identified by retrospectively reviewing the trauma registry at an urban university hospital between 2007 and 2011. Severe extracranial injuries were defined as extracranial injuries with Abbreviated Injury Scale score ≥3, intracranial Abbreviated Injury Scale score <3 and an Injury Severity Score ≥16. In-hospital deaths and patients prescribed antidepressant therapy ≤1 year prior to admission were excluded. Patients were stratified into groups based on pre-admission beta-blocker status. The primary outcome was post-traumatic depression, defined as receiving antidepressants ≤1 year following trauma.RESULTS: Five hundred and ninety-six patients met the inclusion criteria with 11.4% prescribed pre-admission beta-blockade. Patients receiving beta-blockers were significantly older (57 ± 18 vs. 42 ± 17 years, p < 0.001) with lower Glasgow Coma Scale score (12 ± 3 vs. 14 ± 2, p < 0.001). The beta-blocked cohort spent significantly longer in hospital (21 ± 20 vs. 15 ± 17 days, p < 0.01) and intensive care (4 ± 7 vs. 3 ± 5 days, p = 0.01). A forward logistic regression model was applied and predicted lack of beta-blockade to be associated with increased risk of depression (OR 2.7, 95% CI 1.1-7.2, p = 0.04). After adjusting for group differences, patients lacking beta-blockers demonstrated an increased risk of depression (AOR 3.3, 95% CI 1.2-8.6, p = 0.02).CONCLUSIONS: Pre-admission beta-blockade is associated with a significantly reduced risk of depression following severe traumatic injury. Further investigation is needed to determine the beneficial effects of beta-blockade in these instances.

- BACKGROUND: Emergency surgery for colon cancer carries significant morbidity, and studies show more than doubled mortality when comparing elective to emergency surgery. The relationship between postoperative complications and survival has been outlined. Beta-blocker therapy has been linked to improved postoperative outcomes. This study aims to assess the impact of postoperative complications on long-term survival following emergency surgery for colon cancer and to determine whether beta-blockade can reduce complications.STUDY DESIGN: This cohort study utilized the prospective Swedish Colorectal Cancer Registry to identify adults undergoing emergency colon cancer surgery between 2011 and 2016. Prescription data for preoperative beta-blocker therapy were collected from the national drug registry. Cox regression was used to evaluate the effect of beta-blocker exposure and complications on 1-year mortality, and Poisson regression was used to evaluate beta-blocker exposure in patients with major complications.RESULTS: A total of 3139 patients were included with a mean age of 73.1 [12.4] of which 671 (21.4%) were prescribed beta-blockers prior to surgery. Major complications occurred in 375 (11.9%) patients. Those suffering major complications showed a threefold increase in 1-year mortality (adjusted HR = 3.29; 95% CI 2.75-3.94; p < 0.001). Beta-blocker use was linked to a 60% risk reduction in 1-year mortality (adjusted HR = 0.40; 95% CI 0.26-0.62; p < 0.001) but did not show a statistically significant association with reductions in major complications (adjusted IRR = 0.77; 95% CI 0.59-1.00; p = 0.055).CONCLUSION: The development of major complications after emergency colon cancer surgery is associated with increased mortality during one year after surgery. Beta-blocker therapy may protect against postoperative complications.

Tidskriftsartikel (refereegranskat)abstract
- Adrenocortical carcinoma (ACC) is a rare, aggressive tumor that is often detected in an advanced stage. Medical treatment with the adrenotoxic drug mitotane has been used for decades, but critical prospective trials on its role in residual disease or as an adjuvant agent after surgical resection are still lacking. The concept of a critical threshold plasma level of the drug must be confirmed in controlled studies. Because individual responsiveness cannot be predicted, the use mitotane is still advised for nonresectable disease. In case of cortisol or other steroid overproduction, several drugs (e.g., ketoconazole or aminoglutethimide) may be used. Chemotherapy with single agents (e.g., doxorubicin or cisplatin) have been disappointing, with low response rates (< 30%) and a short response duration. Part of this refractoriness may be explained by the fact that ACC tumors express the multidrug-resistance gene MDR-1. Chemotherapy with multiple agents has been tested in smaller series and has resulted in significant side effects. The best results were achieved by the combination of etoposide, doxorubicin, and cisplatin associated with mitotane, achieving a response rate of 54%, including individual complete responses. To be able to make progress in treating advanced ACC disease, adjuvant multicenter trials must be encouraged. When mitotane-based therapies are used, monitored drug levels are mandatory.

Tidskriftsartikel (refereegranskat)abstract
- Liver metastases imply a major problem in patients with carcinoid tumors. Patients with localized disease should always undergo resection for cure. Patients with distant metastatic disease can also undergo resection for potential cure or symptom palliation because of the slow growth rate of many carcinoid tumors. In patients with the midgut carcinoid syndrome and bilobar hepatic disease we have performed primary surgery to relieve such symptoms as intestinal obstruction and ischemia, followed by successive embolizations of the hepatic arteries to reduce functional tumor burden in the liver. For optimal palliation, all patients with residual tumor were treated by octreotide. In a consecutive series of 64 patients with the midgut carcinoid syndrome we thus attained a 5-year survival rate of 70%. Fourteen of the patients underwent intentionally curative surgery (e.g., primary surgery followed by liver surgery). Of these patients, none died from their tumor disease during the period of study. The value of adjunctive interferon therapy is currently under evaluation.

- Background: The role of surgery in global health has gained greater attention in recent years. Approximately 1.8 billion children below 15 years live in low- and middle-income countries (LMIC). Many surgical conditions affect children. Therefore, paediatric surgery requires specific emphasis. Left unattended, the consequences can be dire. Despite this, there is a paucity of data regarding prevalence of surgical conditions in children in LMIC. The present objective was to investigate the prevalence of paediatric surgical conditions in children in a defined geographical area in Eastern Uganda.Method: A cross-sectional study was carried out in the Iganga-Mayuge Health and Demographic Surveillance Site located in Eastern Uganda. Through a two-stage, cluster-based sampling process, 490 households from 49 villages were randomly selected, generating a study population of 1581 children. The children’s caregivers were interviewed, and the children were physically examined by two medical doctors to identify any surgical conditions.Results: The interview was performed with 1581 children, and 1054 were physically examined. Among these, the overall prevalence of any surgical condition was 16.0 per cent (n = 169). Of these, 39 per cent had an unmet surgical need (66 of 169). This is equivalent to a 6.3 per cent prevalence of current unmet surgical need. The most common groups of surgical condition were congenital anomalies and trauma-related conditions.Conclusion: Surgical conditions in children are common in eastern Uganda. The unmet need for surgery is high. With a growing population, the need for paediatric surgical capacity will increase even further. The health care system must be reinforced to provide services for children with surgical conditions if United Nations Sustainability Development Goal 3 is to be achieved by 2030.

- Background: Prophylactic central neck dissection in patients with papillary thyroid carcinoma is controversial. Sentinel node biopsy might be an adjunct to optimize surgical treatment for these patients. Earlier studies reported inconsistent detection rates and diagnostic value of this technique, and the role of sentinel lymph node biopsy in thyroid cancer needs to be established. Patients and methods: During a single-center prospective interventional study between 2010 and 2017, sentinel lymph node biopsy using 99mTc-nanocolloidal albumin tracer was performed on patients undergoing thyroid surgery for suspected thyroid cancer by fine needle aspiration cytology. All eligible patients without clinical lymph node involvement were invited to participate. Central neck dissection was performed on all patients after the detection of sentinel lymph nodes. Results: Ninety-six patients participated in the study. The detection rates of the sentinel node were 67% and 45% by scintigraphy and intraoperative gamma probe, respectively. The detection rate was not associated with Bethesda score, malignancy, or presence of lymph node metastases. Sensitivity, negative predictive value, and accuracy were 80%, 97%, and 98%, respectively, for the sentinel node to represent the status of lymph node metastasis in the central neck compartment. The false negative rate was 20%. Conclusion: Sentinel lymph node biopsy had a low detection rate and only moderate sensitivity in patients with suspected thyroid carcinoma and is not a useful adjunct to surgery in the context of current treatment concepts.

- BACKGROUND: Mortality caused by acute pancreatitis in patients admitted to the hospital has been thoroughly investigated, but knowledge regarding outpatient fatalities is far from complete. The purpose of this study was to assess the incidence and clinical characteristics of patients who have died due to acute pancreatitis occurring outside the hospital. METHODS: Deaths caused by acute pancreatitis in the southern part of Sweden during 1994-2008 were identified at the Department of Forensic Medicine, Lund. A retrospective review of all cases was performed. RESULTS: A total of 50 patients were included, representing approximately 50 of 292 (17%) of all deaths due to acute pancreatitis in the region during this period of time. Median age was 54 (47-69) years and the majority-37 (74%)-were men. The main etiology was alcohol, seen in at least 35 (70%) patients. Twelve (24%) patients were obese. The duration of abdominal pain, in evaluable cases, was 3.0 (1.6-6.2) days. Profound signs of pancreatitis were seen in all patients; 35 (70%) had a necrotising disease according to histopathological examination. Pulmonary changes were common, e.g., bronchopneumonia, pleural effusion, or edema, and all but four had fatty liver. Massive intra-abdominal bleeding was seen in one patient. At least eight patients had a mental disorder, and three were homeless. CONCLUSIONS: Fatal acute pancreatitis occurring outside the hospital accounts for a substantial part of all deaths due to the disease. The incidence seems to decline, and no variation in season was seen. Alcohol was the predominant etiology. Many of the patients lived alone and in poor social conditions.

- The diagnosis of appendicitis is difficult and resource consuming. New inflammatory markers have been proposed for the diagnosis of appendicitis, but their utility in combination with traditional diagnostic variables has not been tested. Our objective is to explore the potential of new inflammatory markers for improving the diagnosis of appendicitis. The diagnostic properties of the six most promising out of 21 new inflammatory markers (interleukin [IL]-6, chemokine ligand [CXCL]-8, chemokine C-C motif ligand [CCL]-2, serum amyloid A [SAA], matrix metalloproteinase [MMP]-9, and myeloperoxidase [MPO]) were compared with traditional diagnostic variables included in the Appendicitis Inflammatory Response (AIR) score (right iliac fossa pain, vomiting, rebound tenderness, guarding, white blood cell [WBC] count, proportion neutrophils, C-reactive protein and body temperature) in 432 patients with suspected appendicitis by uni- and multivariable regression models. Of the new inflammatory variables, SAA, MPO, and MMP9 were the strongest discriminators for all appendicitis (receiver operating characteristics [ROC] 0.71) and SAA was the strongest discriminator for advanced appendicitis (ROC 0.80) compared with defence or rebound tenderness, which were the strongest traditional discriminators for all appendicitis (ROC 0.84) and the WBC count for advanced appendicitis (ROC 0.89). CCL2 was the strongest independent discriminator beside the AIR score variables in a multivariable model. The AIR score had an ROC area of 0.91 and could correctly classify 58.3 % of the patients, with an accuracy of 92.9 %. This was not improved by inclusion of the new inflammatory markers. The conventional diagnostic variables for appendicitis, as combined in the AIR score, is an efficient screening instrument for classifying patients as low-, indeterminate-, or high-risk for appendicitis. The addition of the new inflammatory variables did not improve diagnostic performance further.

- Background: The clinical diagnosis of appendicitis is a subjective synthesis of information from variables with ill-defined diagnostic value. This process could be improved by using a scoring system that includes objective variables that reflect the inflammatory response. This study describes the construction and evaluation of a new clinical appendicitis score. Methods: Data were collected prospectively from 545 patients admitted for suspected appendicitis at four hospitals. The score was constructed from eight variables with independent diagnostic value (right-lower-quadrant pain, rebound tenderness, muscular defense, WBC count, proportion neutrophils, CRP, body temperature, and vomiting) in 316 randomly selected patients and evaluated on the remaining 229 patients. Ordered logistic regression was used to obtain a high discriminating power with focus on advanced appendicitis. Diagnostic performance was compared with the Alvarado score. Results: The ROC area of the new score was 0.97 for advanced appendicitis and 0.93 for all appendicitis compared with 0.92 (p = 0.0027) and 0.88 (p = 0.0007), respectively, for the Alvarado score. Sixty-three percent of the patients were classified into the low- or high-probability group with an accuracy of 97.2%, leaving 37% for further investigation. Seventy-three percent of the nonappendicitis patients, 67% of the advanced appendicitis, and 37% of all appendicitis patients were correctly classified into the low- and high-probability zone, respectively. Conclusion: This simple clinical score can correctly classify the majority of patients with suspected appendicitis, leaving the need for diagnostic imaging or diagnostic laparoscopy to the smaller group of patients with an indeterminate scoring result. © 2008 Société Internationale de Chirurgie.

- Background Patients with suspicion of appendicitis present with a wide range of severity. Score-based risk stratification can optimise the management of these patients. This prospective study validates the Appendicitis Inflammatory Response (AIR) score in patients with suspicion of appendicitis. Method Consecutive patients over the age of five with suspicion of appendicitis presenting at 25 Swedish hospitals emergency departments were prospectively included. The diagnostic properties of the AIR score are estimated. Results Some 3878 patients were included, 821 with uncomplicated and 724 with complicated appendicitis, 1986 with non-specific abdominal pain and 347 with other diagnoses. The score performed better in detecting complicated appendicitis (ROC area 0.89 (95% confidence interval (CI) 0.88-0.90) versus 0.83 (CI 0.82-0.84) for any appendicitis, p < 0.001), in patients below age 15 years and in patients with >47 h duration of symptoms (ROC area 0.93, CI 0.90-0.95 for complicated and 0.87, CI 0.84-0.90 for any appendicitis in both categories). Complicated appendicitis is unlikely at AIR score <4 points (Negative Predictive Value 99%, CI 98-100%). Appendicitis is likely at AIR score >8 points, especially in young patients (positive predictive value (PPV) 96%, CI 90-100%) and men (PPV 89%, CI 84-93%). Conclusions The AIR score has high sensitivity for complicated appendicitis and identifies subgroups with low probability of complicated appendicitis or high probability of appendicitis. The discriminating capacity is high in children and patients with long duration of symptoms. It performs equally well in both sexes. This verifies the AIR score as a valid decision support.

- Civilians constitute 33-51% of victims in armed conflicts. Several reports on civilian injuries exist, but few have focused on injuries afflicting females. We analyzed routinely collected data on weapon-related injuries from the International Committee of the Red Cross (ICRC) hospital in northwestern Pakistan in order to define injury patterns and types of surgical treatment for females. A total of 3028 patient files (376 females) from consecutively admitted patients to the ICRC-hospital in Peshawar from February 2009 to May 2012 were included. Information regarding injury-mechanism, time since injury, vital parameters at admission, type of injury, treatment and basic outcome was extracted from the files and analyzed. Comparisons between gender and age-groups were done by cross-table analyses or nonparametric tests. Females were younger than males (20 vs. 25 years), arrived sooner after injury (24 vs. 48 h) (p amp;lt; 0.001 for both) and were victims of bombs and missiles more frequently (64.4 vs. 54.6%) (p amp;lt; 0.001). Vital parameters such as systolic blood pressure (110 vs. 113 mmHg) and pulse rate (100 vs. 86) were more affected at admission (p amp;lt; 0.001 for both). Females were subjected to surgery (83.0 vs. 77.4%) (p amp;lt; 0.05) and were given blood transfusions more often (18.8 vs. 13.6%) (p amp;lt; 0.01). No differences in amputations or in-hospital mortality were found. Females treated at the ICRC-hospital in northwestern Pakistan are markedly affected by indiscriminate weapons such as bombs and missiles. Their average consumption of surgery is greater than for males, and this might be relevant in planning for staffing and facility needs in similar contexts.
