RESUMO
We aimed to investigate the national trends in the incidence and management of slipped capital femoral epiphysis (SCFE) and to report the need for reoperations. We included all <19-year-old patients hospitalised for SCFE in 2004-2014 in mainland Finland (n=159). Data from the Finnish Care Register for Health Care, Statistics Finland, and Turku University Hospital patient charts were analyse for the incidence of SCFE in 2004-2012, the length of stay, and the type of surgery with respect to age, gender, study year, and season. The reoperations and rehospitalisations in 2004-2014 for SCFE were analysed for 2-10 years after surgery. In 2004 to 2012, primary surgery for SCFE was performed for 126 children. The average annual incidence of SCFE was 1.06/100 000 (95% confidence interval [CI], 0.81-1.38) in girls and 1.35/100 000 (95% CI 1.07-1.70) in boys. The median age at surgery was lower in girls than in boys (11 and 13 years, respectively, p<0.0001). During the study period, there was no significant change in the incidence of SCFE (p=0.9330), the type of primary procedures performed (p=0.9988), or the length of stay after the primary procedure (p=0.2396). However, the length of stay after percutaneous screw fixation was shorter compared with open reduction and fixation (mean 3.4 and 7.9 days, respectively, p<0.0001). There was no significant difference in the rate of reoperations according to the type of primary surgery. In conclusion, the incidence of SCFE and the proportion of different primary surgeries have recently remained stable in Finland.

BACKGROUND: Western Ontario shoulder instability index (WOSI) is a widely used disease-specific self-assessment measurement tool for patients with shoulder instability. The main aim of this study was to translate and cross culturally adapt the WOSI into Finnish language and to test its measurement properties. METHODS: WOSI was translated in Finnish and adapted into an electronic user interface. 62 male patients with traumatic anteroinferior shoulder instability, programmed for stabilizing shoulder surgery, answered the questionnaire twice preoperatively (2 and 0 weeks), and twice postoperatively (3 and 12 months). Additional scoring tools, such as satisfaction to treatment outcome, subjective shoulder value (SSV), Oxford shoulder instability index (OSIS) and Constant score (CS), were used as comparators. The reliability, validity and responsiveness of WOSI were investigated through statistical analysis. RESULTS: Preoperative test-retest results were available for 49 patients, and 54 patients were available at final follow up. The mean WOSI was 57.8 (SD 20.3), 70.4 (SD 18.9), and 85.9 (SD 15.5), at baseline, 3, and 12 months, respectively. There was a statistically significant mean improvement of 28.8 (SD 24.5) in WOSI between baseline and 12 months (p < 0.0001). The intraclass correlation coefficient for the preoperative WOSI was excellent 0.91. At 12 months WOSI had an excellent Pearson's correlation coefficient both with SSV (0.69), OSIS (-0.81), and poor with CS (0.25) scores, confirming our a priori hypothesis. There were no detected floor nor ceiling effects for WOSI pre- or postoperatively. The calculated minimal detectable change was 9.2 and the estimated minimal clinically important difference 13.4 to 18.1. CONCLUSION: Finnish version of WOSI is a reliable and valid tool for assessing health state and improvement after operative treatment of shoulder instability in young male patients.

BACKGROUND: Up to 30% of patients with temporomandibular disorder (TMD) run the risk of progressing to chronic pain with significant disability. This prospective cohort study assessed the effects of baseline pain and general health and psychosocial factors on the presence of clinically significant pain in patients with TMD pain at 1 year after initial consultation. METHODS: 263 primary care patients with TMD pain were included. At the baseline, patients completed a pain questionnaire including a wide range of putative prognostic factors, which were assessed using validated self-report scales. The outcome, clinically significant pain at 1 year was defined as grades IV and III and grades II and I with any disability points on the Graded Chronic Pain Scale (GCPS). Multivariable logistic regression was used to study the association between the outcome and each predictor variable. RESULTS: At 1 year, 26.9% of the patients reported clinically significant pain. The number of previous healthcare visits (OR 1.19, 95% CI 1.02-1.39), pain intensity/dysfunction of other pain conditions (OR 1.35, 95% CI 1.07-1.69), the number of other pain conditions (OR 1.31, 95% CI 0.98-1.74), the number of disability days (OR 1.05, 95% CI 1.00-1.12), and perceived ability to control pain (OR 0.79, 95% CI 0.61-1.01) were associated with the outcome. The area under the curve (AUC) for the whole model indicated acceptable discriminative ability (0.74, 95% CI 0.66-0.82). CONCLUSIONS: Reporting several previous healthcare visits and comorbid pains with high pain intensity and disability signal increased risk for poor prognosis of TMD pain. SIGNIFICANCE: About 27% of primary care TMD pain patients reported clinically significant pain at 1 year after initial consultation. Reporting several previous healthcare visits and comorbid pains with high pain intensity and disability were associated with poor prognosis of TMD pain.

PURPOSE: Reproducibility of two different methods for quantifying fiber tracts by using a diffusion tensor imaging (DTI) sequence suitable for clinical magnetic resonance imaging (MRI) protocols was evaluated. METHODS: DTI of 15 subjects was used to analyze intra-rater and inter-rater reproducibility. Another 10 subjects underwent MRI twice for assessment of between-scan reliability. Ten long association tracts were defined by fiber tracking using inclusion and exclusion regions of interest (ROIs). Whole-tract analysis and tractography-based core analysis were performed, and the effect of fractional anisotropy (FA 0.15/0.30) and turning angle threshold (27°/60°) on reproducibility was evaluated. Additionally, ROI measurements were performed in the core of the tracts. RESULTS: For the tract-based methods, intra-rater and inter-rater reliabilities of FA and mean diffusivity (MD) measurements were excellent. Between-scan reproducibility was good or excellent in 127 of 130 of the measurements. There was no systematic difference in the reproducibility of the FA, MD, and volume measurements depending on the FA or turning angle threshold. For the cross-sectional ROI measurements, reliability showed large variation from poor to excellent depending on the tract. CONCLUSIONS: Compared with the commonly used cross-sectional core ROI method, the tract-based analyses seem to be a more robust way to identify and measure white matter tracts of interest, and provide a novel reproducible tool to perform core analysis.

OBJECTIVE: Endocannabinoids and neuropeptide Y (NPY) promote energy storage via central and peripheral mechanisms. In the hypothalamus, the two systems were suggested to interact. To investigate such interplay also in non-hypothalamic tissues, we evaluated endocannabinoid levels in obese OE-NPY(DßH) mice, which overexpress NPY in the noradrenergic neurons in the sympathetic nervous system and the brain. METHODS: The levels of the endocannabinoids anandamide and 2-arachidonoylglycerol (2-AG) were measured in key regulatory tissues, that is, hypothalamus, pancreas, epididymal white adipose tissue (WAT), liver and soleus muscle, over the development of metabolic dysfunctions in OE-NPY(DßH) mice. The effects of a 5-week treatment with the CB1 receptor inverse agonist AM251 on adiposity and glucose metabolism were studied. RESULTS: 2-AG levels were increased in the hypothalamus and epididymal WAT of pre-obese and obese OE-NPY(DßH) mice. Anandamide levels in adipose tissue and pancreas were increased at 4 months concomitantly with higher fat mass and impaired glucose tolerance. CB1 receptor blockage reduced body weight gain and glucose intolerance in OE-NPY(DßH) to the level of vehicle-treated wild-type mice. CONCLUSIONS: Altered endocannabinoid tone may underlie some of the metabolic dysfunctions in OE-NPY(DßH) mice, which can be attenuated with CB1 inverse agonism suggesting interactions between endocannabinoids and NPY also in the periphery. CB1 receptors may offer a target for the pharmacological treatment of the metabolic syndrome with altered NPY levels.
RESUMO
BACKGROUND: Both pregnancy and high vitamin D concentration seem to generate a protective environment against multiple sclerosis (MS) relapses. Longitudinal case-control analysis of vitamin D concentrations during pregnancy and lactation of MS mothers is lacking. AIMS OF THE STUDY: To examine serum 25-hydroxyvitamin-D3 levels of MS patients during and after pregnancy and compare these to the levels measured in healthy controls. METHODS: Fifteen relapsing-remitting MS mothers underwent repeated testing for 25-hydroxyvitamin-D3 at 10-12, 26-28 and 35-37 gestational weeks and 1, 3 and 6 months post-partum. An identical series of samples was collected from six control mothers. RESULTS: The prevalence of vitamin D deficiency (<50 nmol/l) during pregnancy was high (73%) among MS patients. Vitamin D levels were significantly higher during pregnancy when compared to early post-partum values among MS patients. At the end of the follow-up period, the vitamin D levels returned to levels observed in early pregnancy. In healthy controls, the alterations during and after pregnancy were similar in nature, but the vitamin D concentrations were higher at all time points when compared to MS patients (P = 0.037). CONCLUSIONS: Vitamin D deficiency during the pregnancy and lactation seems to be common in mothers with MS and needs to be treated adequately.

OBJECTIVE: Studies on the presenting symptoms of glioma in adults in the age of readily available MRI imaging are scarce. This study investigates presenting symptoms of glioma and assesses the correlations of the presenting symptoms with patient age and histopathological class of the tumor. MATERIALS AND METHODS: A retrospective review of the medical records of histologically verified glioma patients treated in Turku University Hospital, during 2006-2010, was conducted. The associations between the presenting symptoms and other covariates were assessed individually. RESULTS: One hundred and fifty patients were ascertained. The most common presenting symptoms of glioma were seizure and cognitive disorder. Patients presenting with seizures were younger than patients with cognitive disorders, and the grade of the tumor was also found to significantly correlate with the most common presenting symptoms. Age group and tumor grade were statistically significant factors of cognitive disorder (P = 0.0037 and P = 0.0069) and age group of seizure (P = 0.0065). The associations between the presenting symptoms and the anatomical location, spread into adjacent brain areas, or laterality of the tumor or site of diagnosis were found to be statistically insignificant. Headache was not a common presenting symptom in glioma patients. CONCLUSIONS: The main presenting symptoms of glioma in adults in the MRI age still are seizures and cognitive disorder. Patient age and tumor grade correlate positively with the incidence of cognitive disorder and patient age negatively with incidence of seizure as a presenting symptom. Headache is an uncommon manifestation and does not appear as a sole symptom.

Acrylic occlusal appliances (OAs) have been used for temporomandibular disorders and sleep bruxism, but the effects of the treatment are still insufficiently evaluated. Two all-night polysomnographic recordings were made in a sleep laboratory on 14 bruxists (9 females and 5 males with mean age of 27·5 years). The measurement included basic polysomnography with additional masseter muscle electromyogram and movement recording (static charge-sensitive bed method) using randomisation. The base night recording was followed by the second study night after 8 weeks regular use of OA. The OA was made on the occlusal surface of the teeth of the upper jaw, and it was used at night time during the study period. With the OA, rapid eye movement sleep changed from 23·3% to 19·6% (P = 0·078), and slow wave sleep increased significantly from 10·2% to 14·7% (P = 0·039). Masseter contraction (MC) episodes occurred with similar frequency (9·7 vs. 10·5 episodes per hour, P = 0·272). The intensity of the rhythmic MC bursts within an episode decreased from 5·5 to 4·4 (P = 0·027). The groups were post hoc divided into responders and non-responders using a 20% change in MC episode per hour as a cut-off point. The results indicated that 43% of bruxists increased activity (negative responders), while 36% decreased (positive responders), and in 21%, there was no change in the level. It is concluded that OA does not have significant feedback inhibition on masseter muscle motor activity during sleep. However, OA may increase slow wave sleep.

We have compared three different methods of treating symptomatic non-traumatic tears of the supraspinatus tendon in patients above 55 years of age. A total of 180 shoulders (173 patients) with supraspinatus tendon tears were randomly allocated into one of three groups (each of 60 shoulders); physiotherapy (group 1), acromioplasty and physiotherapy (group 2) and rotator cuff repair, acromioplasty and physiotherapy (group 3). The Constant score was assessed and followed up by an independent observer pre-operatively and at three, six and twelve months after the intervention. Of these, 167 shoulders were available for assessment at one year (follow-up rate of 92.8%). There were 55 shoulders in group 1 (24 in males and 31 in females, mean age 65 years (55 to 79)), 57 in group 2 (29 male and 28 female, mean age 65 years (55 to 79)) and 55 shoulders in group 3 (26 male and 29 female, mean age 65 years (55 to 81)). There were no between-group differences in the Constant score at final follow-up: 74.1 (sd 14.2), 77.2 (sd 13.0) and 77.9 (sd 12.1) in groups 1, 2 and 3, respectively (p = 0.34). The mean change in the Constant score was 17.0, 17.5, and 19.8, respectively (p = 0.34). These results suggest that at one-year follow-up, operative treatment is no better than conservative treatment with regard to non-traumatic supraspinatus tears, and that conservative treatment should be considered as the primary method of treatment for this condition.

This registry study was set up to evaluate the effect of smoking on the pre-operative status, intraoperative findings, and post-operative status after rotator cuff reconstruction. Five hundred seventy-six consecutive shoulders with primarily arthroscopically repaired penetrating rotator cuff tear were followed up. Tobacco consumption was recorded as pack-years. Age-adjusted Constant score was used as an outcome measure. Five hundred sixty-four patients were available for 1-year follow-up (dropout rate 2%). One hundred fourteen (20%) and 450 (80%) patients were pre-operatively recorded to be smokers and non-smokers, respectively. The gender distribution did not differ between the groups (P = 0.286). The mean age of all patients was 55 years in smokers (SD 9.1) and 61 years in non-smokers (SD 9.4) (P < 0.001). There was no statistically significant difference in pre-operative Constant score (P = 0.075) or mean size of intraoperatively measured tendon tear (P = 0.290) between the groups. At final follow-up, there was a statistically significant difference in Constant scores between smokers [71 (SE 1.4)] and non-smokers [75 (SE 0.7)] (P = 0.017). The pack-years of smoking correlated with neither the Constant score (P = 0.815) nor the size of the tear (P = 0.786). We conclude that operatively treated rotator cuff tear patients who smoked were significantly younger than non-smokers, and that smoking was associated with lower post-operative Constant score.

The Phenotype MicroArray (PM) technology was used to study the metabolic characteristics of 29 Salmonella strains belonging to seven serotypes of S. enterica spp. enterica. Strains of serotypes Typhimurium (six strains among definite phage types DTs 1, 40 and 104) and Agona (two strains) were tested for 949 substrates, Enteritidis (six strains of phage type PT1), Give, Hvittingfoss, Infantis and Newport strains (two of each) were tested for 190 substrates and seven other Agona strains for 95 substrates. The strains represented 18 genotypes in pulsed-field gel electrophoresis (PFGE). Among 949 substrates, 18 were identified that could be used to differentiate between the strains of those seven serotypes or within a single serotype. Unique metabolic differences between the Finnish endemic Typhimurium DT1 and Agona strains were detected, for example, in the metabolism of D-tagatose, D-galactonic acid gamma-lactone and L-proline as a carbon source. Thus, the PM technique is a useful tool for identifying potential differential markers on a metabolic basis that could be used for epidemiological surveillance.

In June 2008 an outbreak of gastroenteritis was registered in Sunny Beach resort situated on the Black Sea coast in Bulgaria, affecting 14 employees of a hotel, five of whom tested positive for Salmonella Enteritidis. During June-July 2008 four sporadic S. Enteritidis cases were also reported and two of them were foreign tourists. In the same period S. Enteritidis cases connected with travel to Bulgaria were reported to the European Centre for Disease Prevention and Control (ECDC) from Finland, United Kingdom, Sweden, Germany and Norway. We describe a study performed to find out relatedness between Bulgarian and Finnish S. Enteritidis isolates using phage typing (PT) and pulse-field gel electrophoresis (PFGE). Fifteen S. Enteritidis isolates from Bulgaria and 195 from Finland (including 28 from travellers to Bulgaria) were phage typed. Within Bulgarian isolates four different PTs were found and PT6c with eight strains was predominant. Nineteen out of 28 strains isolated from the Finns visiting Bulgaria belonged also to PT6c. PFGE typing (with one enzyme) of all S. Enteritidis PT6c strains (8 Bulgarian and 19 Finnish isolates) showed indistinguishable PFGE profile. The typing results thus demonstrated a link between Bulgarian and Finnish S. Enteritidis isolates. We conclude that S. Enteritidis PT6c was the cause of salmonella outbreak in Sunny Beach and was exported to Finland, and likely to the United Kingdom, Norway, Sweden and Germany.

Fine structure of nerve fibres and terminals in the rat cornea was studied after fixation with glutaraldehyde and osmium tetroxide or with potassium permanganate. Superior cervical and/or ciliary ganglionectomy as well as ophthalmic neurotomy were performed in order to verify the origin of the corneal nerves. In the control corneas axon profiles with granular vesicles were observed in the stroma. Other axons containing agranular vesicles were found both in the stroma and in the epithelium. Superior cervical ganglionectomy abolished only the axons containing granular vesicles but did not affect the corneal blink reflex. Ciliary ganglionectomy induced more conspicuous changes in both stromal and intraepithelial axon profiles. The corneal reflex was, however, normal. Some of the axons containing agranular vesicles also showed degenerative changes. However, intact axon profiles with agranular vesicles were seen even after extirpation of both the ciliary ganglion and the superior cervical ganglion (combined autonomic ganglionectomy). On the other hand, all axon profiles with agranular vesicles disappeared after coagulation of the ophthalmic and maxillary nerves (sensory denervation). This operation destroyed most of the axons in all parts of the cornea and abolished the blink reflex. It is concluded that the axon profiles in the corneal epithelium, containing agranular vesicles, are sensory axons of the trigeminal nerve. A possible role of the vesicles in sensory nerves is discussed.
