- Summary. The aim of this study was to examine the prevalence and incidence of HIV and hepatitis B and C (HBV and HCV) among injecting drug users in a Swedish needle exchange programme (NEP) and to identify risk factors for blood-borne transmission. A series of serum samples from NEP participants enrolled from 1997 to 2005 were tested for markers of HIV, HBV and HCV (including retrospective testing for HCV RNA in the last anti-HCV-negative sample from each anti-HCV seroconverter). Prevalence and incidence were correlated with self-reported baseline characteristics. Among 831 participants available for follow-up, one was HIV positive at baseline and two seroconverted to anti-HIV during the follow-up of 2433 HIV-negative person-years [incidence 0.08 per 100 person-years at risk (pyr); compared to 0.0 in a previous assessment of the same NEP covering 1990-1993]. The corresponding values for HBV were 3.4/100 pyr (1990-1993: 11.7) and for HCV 38.3/100 pyr (1990-1993: 27.3). HCV seroconversions occurred mostly during the first year after NEP enrolment. Of the 332 cases testing anti-HCV negative at enrolment, 37 were positive for HCV RNA in the same baseline sample (adjusted HCV incidence 31.5/100 pyr). HCV seroconversion during follow-up was significantly associated with mixed injection use of amphetamine and heroin, and a history of incarceration at baseline. In this NEP setting, HIV prevalence and incidence remained low and HBV incidence declined because of vaccination, but transmission of HCV was persistently high. HCV RNA testing in anti-HCV-negative NEP participants led to more accurate identification of timepoints for transmission.

- Objectives: Simple decompression is an accepted surgical treatment of ulnar nerve entrapment at the elbow (UNE). Our purpose was to evaluate the outcome and potential predictors for the outcome after simple decompression in UNE.Methods: All surgically treated UNE cases (from 2004-2008) at our department were studied retrospectively. Out of 285 primary surgeries, 242 primary simple ulnar nerve decompressions were included. Medical records, including electrophysiologic protocols, were reviewed and postoperative outcome was graded: 1) cured/improved and 2) unchanged/worsened symptoms, based on surgeon-evaluated outcome.Results: Of the 242 simple decompressions (122 males and 120 females; median age 50.5 years), 101 cases were students, retired, un-employed, or on a long-term sick-leave and 112 had manual, blue-collar type of careers. 189 cases were cured or improved, while 53 cases had no change in, or even worsened, symptoms. Gender, presence of smoking, or associated diseases did not affect outcome, while a tendency was observed for higher age, a manual occupation and constant symptoms. Out of 196 cases electrophysiologically examined,155 cases showed signs of ulnar nerve affection (56 reduced conduction velocity; 19 conduction block; 80 axonal degeneration; latter two groups significantly worse outcome).Conclusion: Patients with a preoperatively electrophysiologically diagnosed nerve conduction block or axonal degeneration have higher risk of not being cured or improved after simple decompression in UNE. Older patients, those with a manual profession, and constant symptoms of UNE tend to be less improved after surgery.

- Objectives: Knowledge is scarce about the outcome of revision surgery for recurrent or persistent ulnar nerve entrapmentat the elbow (UNE). We studied the outcome of subcutaneous (SCT) and submuscular (SMT) ulnar nerve transpositionsdue to UNE, analyzing both primary and revision surgeries, aiming to identify predictors for revision surgery.Methods: All surgically treated UNE cases (2004-2008) at our department were studied retrospectively. The initial population of surgically treated patients included 285 primary and 52 revision surgeries. Forty-three of the former were transpositions (15 SCT and 28 SMT) and 44 (7 SCT and 37 SMT) of the latter, which were the ones included in the present study.Medical records, including electrophysiological protocols, were reviewed and the postoperative outcome was graded as 1)cured/improved, and 2) unchanged/exacerbated symptoms, based on the patient-reported and surgeon-evaluated outcome.Results: The frequency of concomitant systemic diseases (p<0.001), musculoskeletal conditions (p=0.029) and CTS(p=0.048) was higher in revision than in primary surgery cases. Both primary (79%) and revision SMT (76%) cases had ahigh frequency of ulnar nerve subluxation. Primary SMT cases had a higher frequency of ulnar nerve impact found throughelectrophysiological examination (p=0.045), while revision SMT cases had normal electrophysiological findings or reducedulnar nerve conduction velocity (not significant; p=0.10). The satisfaction rate was 79-93% of primary transposition surgeries and 73-86% of revision transposition surgeries.Conclusion: Patients with comorbidity with other systemic diseases, musculoskeletal conditions or concomitant CTS havea higher risk of UNE relapse and need revision surgery. Surgeons should assess any tendency for peroperative subluxationat primary surgery for UNE, proceeding with concomitant transposition of the nerve to minimize the need for revision surgery.Key words: Ulnar nerve, entrapment, submuscular ulnar nerve transposition, subcutaneous ulnar nerve transposition,electrophysiology, outcome

- Conclusion: Alpha B-crystallin was found to be an independent prognostic marker for poor prognosis in oral cavity tumours. For oropharyngeal cancer, alpha B-crystallin had no prognostic value. Objective: The aim of this study was to see if earlier findings of alpha B-crystallin as an independent prognostic marker, and SPARC/osteonectin, PAI-1 and uPA as a prognostic combination for poor outcome in squamous cell carcinoma (SCC) of the head and neck could be confirmed in a new set of tumours. Methods: In a consecutive series of patients, assessed and primarily treated at a tertiary referral centre, histological sections from 55 patients with oral and SCC (OOPHSSC) with complete clinical data and follow-up were obtained. Oral and oropharyngeal tumours were studied separately. Immunohistochemical detection of alpha B-crystallin, SPARC/osteonectin, PAI-1 and uPA expression was performed. Results: Thirty-five patients had an oral tumour and 20 patients an oropharyngeal tumour. Twenty-five oral tumours stained negatively and 10 positively for alpha B-crystallin. For oropharyngeal tumours the figures were 15 negatively and 5 positively. Median disease-specific survival (DSS) for both sites was 33.8 and 11.9 months, for negative and positive alpha B-crystallin staining, respectively (p=0.046). For the oral cavity, median DSS was 27.3 months for negative tumours and 7.5 months for positive tumours (p=0.012). Corresponding figures for oropharyngeal tumours were 33.8 and 34.1 months (p=0.95). Thus, significance in survival was only found in oral cavity tumours. In multivariate analyses there were no significant differences in DSS in the oropharyngeal group when adjusted for tumour size (T status) and presence of neck node metastasis (N status). In the oral cavity group, the significantly better DSS for negative tumours became even stronger when adjusted for T and N status. No statistical difference was found in DSS between positive and negative staining for SPARC/osteonectin, PAI-1 or uPA.

- CONCLUSION: No statistically significant 5-year survival difference was seen in patients with oral and oropharyngeal squamous cell carcinoma (OOPSCC) between high-risk HPV-positive and -negative groups in this population-based study. OBJECTIVES: To see if the formerly observed higher risk for recurrence or second primary tumour (SPT) in high-risk HPV-positive patients with OOPSCC corresponds to worse survival. METHODS: A total of 128 consecutive, previously untreated patients with OOPSCC, who were part of a population-based case-control study in southern Sweden during 2000-2004, were included. A mouthwash sample was collected and exfoliated cells were collected with cotton-tipped swabs from the tonsillar fossa and the tumour. Specimens were analysed for HPV DNA using nested polymerase chain reaction (PCR). Disease-specific survival (DSS) and DSS difference between HPV-negative and HPV-positive patients were calculated. The relationship between age, stage, high-risk HPV status and DSS was assessed. Oral and oropharyngeal tumours were assessed separately. RESULTS: Mean DSS in months was 80.7/68.6 (high-risk HPV-negative/high-risk HPV-positive) for oral cavity tumours (p = 0.18) and 67.6/78.3 (high-risk HPV-negative/high-risk HPV-positive) for oropharyngeal tumours (p = 0.47). For oral cavity tumours, age, T status, N status and stage all showed significant differences in DSS. For oropharyngeal tumours, no significant difference regarding DSS was found.

- More than a million childhood diarrhoeal episodes occur worldwide each year, and in developed countries a considerable part of them are caused by viral infections. In this study, we aimed to search for genetic variants associated with diarrhoeal disease in young children by meta-analyzing genome-wide association studies, and to elucidate plausible biological mechanisms. The study was conducted in the context of the Early Genetics and Lifecourse Epidemiology (EAGLE) consortium. Data about diarrhoeal disease in two time windows (around 1 year of age and around 2 years of age) was obtained via parental questionnaires, doctor interviews or medical records. Standard quality control and statistical tests were applied to the 1000 Genomes imputed genotypic data. The meta-analysis (N=5758) followed by replication (N=3784) identified a genome-wide significant association between rs8111874 and diarrhoea at age 1 year. Conditional analysis suggested that the causal variant could be rs601338 (W154X) in the FUT2 gene. Children with the A allele, which results in a truncated FUT2 protein, had lower risk of diarrhoea. FUT2 participates in the production of histo-blood group antigens and has previously been implicated in the susceptibility to infections, including Rotavirus and Norovirus Gene-set enrichment analysis suggested pathways related to the histo-blood group antigen production, and the regulation of ion transport and blood pressure. Among others, the gastrointestinal tract, and the immune and neuro-secretory systems were detected as relevant organs. In summary, this genome-wide association meta-analysis suggests the implication of the FUT2 gene in diarrhoeal disease in young children from the general population.

- Welding fume consists of metal fumes, e.g., manganese (Mn) and gases, e.g., ozone. Particles in the respirable dust (RD) size range dominate. Exposure to welding fume could cause short- and long-term respiratory effects. The prevalence of work-related symptoms among mild steel welders was studied, and the occupational exposure to welding fumes was quantified by repeated measurements of RD, respirable Mn, and ozone. Also the variance components were studied.
