Book (other academic/artistic)abstract
- Akut ortopedi beskriver hur man handlägger patienter som kommer till akutmottagningen med skador eller sjukdomstillstånd i rörelseapparaten. För varje tillstånd beskrivs kortfattat vad läsaren ska och kan göra själv, men också när det är lämpligt att konsultera en mer erfaren kollega.Boken inleds med att kort beskriva undersökningsmetodik, preoperativ bedömning, ortopediska skador och smärttillstånd samt praktiska råd rörande smärtlindring, injektioner/punktioner och gipsteknik. Därefter följer huvudavsnittet som omfattar alla de skador, smärttillstånd och infektioner som kan drabba respektive kroppsdel. Boken avslutas med ett avsnitt om posttraumatiska och postoperativa tillstånd.Akut ortopedi är skriven främst för medicinstudenter, AT-läkare och nyblivna jourhavande i ortopedi, men är också lämplig för övrig personal som är verksam på landets akutmottagningar. Boken vänder sig också till läkare och sjuksköterskor inom primärvården liksom till sjukgymnaster och arbetsterapeuter som arbetar med patienter med ortopediska besvär. Priset gäller för varje separat artikel i serien.

Journal article (peer-reviewed)abstract
- Background/Aims: There is an established association between the multiple endocrine neoplasia type 1 (MEN 1) syndrome and foregut carcinoids. Some registry studies also indicate that offspring to carcinoid patients run an increased risk of developing a carcinoid tumor themselves. However, there are only scattered reports of gastrointestinal carcinoids in two generations. The aim of this study was to describe the clinical characteristics as well as the histopathological, immunohistochemical (IHC) and genetic data of metastasizing ileal carcinoids in three consecutive first-degree relatives. Methods: The histopathological and IHC analyses were performed on newly cut sections of the tumor specimens and included growth pattern, proliferation index (Ki67) as well as expression of established neuroendocrine markers and recently introduced cocaine-amphetamine-regulated transcript (CART). The genetic analyses were focused on establishing whether a connection with the MEN 1 syndrome existed in this family, by means of mutation screening using polymerase chain reaction, multiple ligation-dependent probe amplification, and genotyping using fluorescent-labeled microsatellite markers. Results: Histopathology and IHC revealed that the tumors were virtually identical, with only minor differences in proliferation index and expression of CART. Genetic analyses indicated that the inheritance of the small bowel carcinoids in the family was not linked to the MEN1 gene. Conclusion: Metastasizing small bowel carcinoids have been found in first-degree relatives in three consecutive generations. All three tumors were very similar when characterized by histopathology and IHC. Based on clinical findings and genetic analyses, it seems unlikely, although not completely excluded, that inheritance was linked to the MEN 1 syndrome. Copyright (c) 2010 S. Karger AG, Basel

Doctoral thesis (other academic/artistic)abstract
- Small bowel carcinoid tumours arising from enterochromaffin cells in the jejunum and ileum are neuroendocrine tumours (NETs) characterized by secretion of serotonin, tachykinins and other bioactive substances. These substances may lead to the typical carcinoid syndrome as well as pronounced fibrosis locally and in the heart. Although the most frequent histological subtype of malignancy in the small bowel, small bowel carcinoids are rare and therefore difficult to study. We found that previous studies either described selected patients at referral centres, or were based on limited data from large registries. The main objective of this thesis was to investigate small bowel carcinoid patients from a geographically defined cohort with no selection bias.PAPERS I AND IIThe aims of papers I and II were to investigate the incidence, histopathological characteristics, stage atdiagnosis, symptomatology, surgical treatment, prognostic factors and survival of small bowel carcinoid.All patients resident in Jönköping County when diagnosed with small bowel carcinoid between 1960 and2005 were eligible for inclusion. After thorough review of medical records and reexamination of availabletumour specimens, 145 patients were included.A higher incidence of small bowel carcinoid than previously described was found: 1.12 per 100,000 persons and year. The incidence increased during the study period. Symptoms were most often uncharacteristic: the carcinoid syndrome was seen in only 13% of symptomatic patients. Many small bowel carcinoid tumours presented as surgical emergencies without preceding symptoms, often as intestinal obstruction (35%) caused by mesenteric fibrosis. The majority of small bowel carcinoid tumours had metastasized to the mesentery or the liver at diagnosis. Disease-specific survival after 5 years was 75.0% and after 10 years 63.5%. Independent prognostic factors for worse disease-specific survival were higher age at diagnosis, more advanced disease stage at diagnosis and incomplete tumour resection. Completeness of resection was of particular importance in patients with regional metastases.PAPER IIIThere are previous case reports describing small bowel carcinoid in two first-degree relatives, but it is unknown whether this represents hereditary disease forms or chance. Paper III was the first article to describe metastasizing ileal carcinoid tumours in three consecutive generations − strongly suggestive of a hereditary disease form.PAPER IVWe recently demonstrated expression of cocaine- and amphetamine-regulated transcript (CART) in several types of NETs, including small bowel carcinoid. The aim of paper IV was to investigate whether content of CART in small bowel carcinoid tumours is associated with tumour characteristics, symptoms and survival. CART expression was examined in all available tumour specimens from the patients in Papers I and II − 97 patients were included.Presence of CART IR tumour cells was associated with histological grade, but not with stage or age. CART expression in small bowel carcinoid tumours was not associated with clinical symptoms. Increasing levels of CART IR in small bowel carcinoid tumour cells was associated with worse disease-specific survival. CART was also found to increase cell viability in an enteroendocrine cell line in vitro. The results suggest that CART could be used as a prognostic biomarker and that CART is a potential anti-tumour treatment target.

Journal article (peer-reviewed)abstract
- Background: This retrospective study describes the epidemiology of small bowel carcinoids in a geographically defined population, with no other selection bias. Methods: All patients (n = 145) resident in Jönkoping County when diagnosed with carcinoid in the jejunum or ileum from 1960 to 2005 were included. Medical records were reviewed in detail, and tumor specimens were histopathologically and immunohistochemically reexamined when required (n = 44). Results: The annual age-adjusted incidence of small bowel carcinoids was 1.12 (95% confidence interval 0.95-1.31) per 100,000 persons. Median age at diagnosis was 69 years. The predominating presenting symptom was uncharacteristic abdominal pain (50%), whereas a smaller number suffered from typical flushes (13%). Surprisingly, 14% presented with overt gastrointestinal hemorrhage. Most of the patients diagnosed based on their symptoms had metastases at diagnosis (44% regional, 40% distant). Metastasized tumors by definition belong to World Health Organization (WHO) histopathologic group 2; and when reexamined, most (83%) of the localized tumors were also found to belong to WHO group 2. Conclusions: In comparison to previous reports, a higher age-adjusted incidence of small bowel carcinoids was observed, and the patients were clearly older at the time of diagnosis. Even with metastatic disease, the presenting symptoms were usually uncharacteristic, and the carcinoid syndrome was infrequently seen.

Journal article (peer-reviewed)abstract
- Purpose: Cocaine- and amphetamine-regulated transcript (CART) peptide exerts several regulatory functions acting both as neurotransmitter and hormone. We recently showed that CART is expressed in various neuroendocrine tumors, including small bowel carcinoid. The main objective of the present study was to examine whether CART expression is associated with survival in small bowel carcinoid patients. Secondary aims were to assess if CART expression is associated with other tumor characteristics or clinical symptoms.Experimental Design: Specimens from 97 patients with small bowel carcinoids were examined for CART expression using immunohistochemistry and in situ hybridization. A CART score was introduced based on the proportion of CART immunoreactive cells. On inclusion, specimens were examined by routine histopathological methods and detailed clinical patient data were retrieved. The effect of CART on cell viability was assessed in vitro using an enteroendocrine cell line.Results: Expression of CART (P = 0.011), and increasing CART score (P = 0.033) were associated with worse disease-specific survival. Adjusting for age, disease stage and tumor grade in multivariable analysis, CART expression was still associated with worse survival (Low CART hazard ratio (HR) 5.47, 95% confidence interval (CI) 0.71 to 42.46; and High CART HR 9.44, 95% CI 1.14 to 78.14). Expression of CART correlated with higher tumor grade, but not with age or disease stage, neither with weight loss or any other symptom. Supporting our clinical data, we found that CART promoted tumor cell viability in vitro.Conclusion: Expression of CART in small bowel carcinoid tumors is associated with worse survival.

Journal article (peer-reviewed)abstract
- Purpose: Total lobectomy is currently recommended also in benign thyroid disease in order to reduce the risk of goitre recurrence, an approach claimed not to increase post-operative morbidity. The aim of the study was to analyse risk factors for recurrent laryngeal nerve (RLN) palsy during neck surgery, with particular interest in complications after total lobectomy and subtotal resection, respectively.Methods: All consecutive patients operated for thyroid and parathyroid diseases at one institution between 1984 and 2011 were prospectively recorded, and 1,322 patients were included. Patients with permanent post-operative RLN palsy were re-examined in 2011.Results: The risk of permanent RLN palsy after parathyroid surgery was 0.3 %. Patients operated for thyroid cancer had a 5.9 % risk of permanent nerve injury, higher than that of patients with benign thyroid disease (1.4 %; P = 0.029). Independent risk factors for RLN paralysis after benign thyroid surgery were intrathoracic goitre (odds ratio (OR), 3.57; 95 % confidence interval, 1.70-7.48), ipsilateral redo-surgery (OR, 3.64; 1.00-13.28) and total lobectomy (OR, 2.41; 1.05-5.55). At long-time follow-up (median, 10 years), 7 of 12 patients with permanent RLN palsy still suffered moderate or severe symptoms.Conclusions: RLN paralysis is an infrequent complication after neck surgery, but with major negative impact on patients' well-being when permanent. Hemithyroidectomy/total thyroidectomy is increasingly preferred over subtotal resection in multinodular goitre. This is supported by an increased risk of RLN injury during redo-surgery for recurrency but should be carefully weighed against individual risk factors for nerve palsy, including surgical experience and volume.

Journal article (peer-reviewed)abstract
- Purpose: To investigate whether celiac disease risk haplotypes HLA-DQ2 and DQ8 also increase the risk for developing small intestinal neuroendocrine tumor (SI-NET).Methods: Thirty-five patients with serotonin-producing jejunal and ileal SI-NET were examined with HLA-DQ genotyping and serology for IgA anti-tissue transglutaminase (tTG) antibodies.Results: Twenty-one patients (60 %) carried HLA-DQ2 or DQ8, twice the frequency of the general population (P < 0.001). In particular DQ2 was overrepresented (P = 0.013). Gender, age, disease stage, histopathological grade, or multifocality of primary tumor did not differ between patients with DQ2 or DQ8 and patients with other HLA-DQ haplotypes. No patient in the study was diagnosed with celiac disease (latent or symptomatic) as anti-tTG antibodies were negative in all 35.Conclusion: HLA-DQ haplotypes associated with celiac disease are overrepresented also in patients with SI-NET, in particular HLA-DQ2.

Journal article (peer-reviewed)abstract
- BACKGROUND: Previous studies of small bowel carcinoid tumours usually presented overall or relative survival. This study, in addition, evaluated disease-specific survival in a cohort of patients in a geographically defined population.METHODS: Patients diagnosed with carcinoid of the jejunum or ileum in Jönköping County between 1960 and 2005 were eligible for inclusion. Available tumour specimens were re-examined to confirm the diagnosis. Medical records and pathology reports were reviewed in detail.RESULTS: A total of 145 patients were included in the study. One hundred and thirty-five patients underwent surgery in connection with the diagnosis. Resection was considered complete (R0) in 74 patients (54·8 per cent). Only two localized tumours recurred, whereas no patient with distant metastases was cured. Patients with regional metastases who underwent R0 resection had a better survival than patients with incomplete resection (P = 0·005), and a majority of patients remained recurrence-free. Median overall survival was 7·2 years and median disease-specific survival 12·3 years. In multivariable analysis, age 61-74 years (hazard ratio (HR) 3·78, 95 per cent confidence interval 1·86 to 7·68), age 75 years or more (HR 3·96, 1·79 to 8·74), distant metastases (HR 14·44, 1·59 to 131·36) and incomplete tumour resection (HR 2·71, 1·11 to 6·61) were associated with worse disease-specific survival. Later time period of diagnosis (HR 0·45, 0·24 to 0·84) was associated with better disease-specific survival.CONCLUSION: Age, disease stage and complete resection were identified as independent prognostic factors for survival in patients with small bowel carcinoid tumours. The importance of achieving R0 resection is therefore emphasized.

Journal article (peer-reviewed)abstract
- Background: Major adverse cardiac events (MACEs) are a common cause of deathafter non-cardiac surgery. Despite evidence for the benefitof aspirin for secondary prevention, it is often discontinuedin the perioperative period due to the risk of bleeding. Methods: We conducted a randomized, double-blind, placebo-controlledtrial in order to compare the effect of low-dose aspirin withthat of placebo on myocardial damage, cardiovascular, and bleedingcomplications in high-risk patients undergoing non-cardiac surgery.Aspirin (75 mg) or placebo was given 7 days before surgery andcontinued until the third postoperative day. Patients were followedup for 30 days after surgery. Results: A total of 220 patients were enrolled, 109 patients receivedaspirin and 111 received placebo. Four patients (3.7%) in theaspirin group and 10 patients (9.0%) in the placebo group hadelevated troponin T levels in the postoperative period (P=0.10).Twelve patients (5.4%) had an MACE during the first 30 postoperativedays. Two of these patients (1.8%) were in the aspirin groupand 10 patients (9.0%) were in the placebo group (P=0.02). Treatmentwith aspirin resulted in a 7.2% absolute risk reduction [95%confidence interval (CI), 1.3–13%] for postoperative MACE.The relative risk reduction was 80% (95% CI, 9.2–95%).Numbers needed to treat were 14 (95% CI, 7.6–78). No significantdifferences in bleeding complications were seen between thetwo groups. Conclusions: In high-risk patients undergoing non-cardiac surgery, perioperativeaspirin reduced the risk of MACE without increasing bleedingcomplications. However, the study was not powered to evaluatebleeding complications.
