The aim of this article is to provide a state-of-the-art review for treatment of acute, total proximal hamstring tendon ruptures. For total proximal hamstring tendon ruptures, early (<2-3 w) surgical refixation minimizes muscle atrophy and facilitates a somewhat predictable time course for healing and rehabilitation. A postoperative rehabilitation program is detailed that has been used by one physical therapist for the past 7 years on over 200 patients with surgical repair for total proximal hamstring tendon rupture. One re-rupture has occurred, 7 months after surgery, following the rehabilitation program described herein. The rehabilitation program, including avoidance of postoperative bracing, appears effective for total proximal hamstring ruptures. Early surgery together with a specific rehabilitation program appears to be the treatment of choice for timely and safe return to sport and an active lifestyle.

Circulation: Arrhythmia and Electrophysiology | Year: 2015
Background - Early diagnosis and risk stratification is of clinical importance in the long QT syndrome (LQTS), however, little genotype-specific data are available regarding fetal LQTS. We investigate third trimester fetal heart rate, routinely recorded within public maternal health care, as a possible marker for LQT1 genotype and phenotype. Methods and Results - This retrospective study includes 184 fetuses from 2 LQT1 founder populations segregating p.Y111C and p.R518X (74 noncarriers and 110 KCNQ1 mutation carriers, whereof 13 double mutation carriers). Pedigree-based measured genotype analysis revealed significant associations between fetal heart rate, genotype, and phenotype; mean third trimester prelabor fetal heart rates obtained from obstetric records (gestational week 29-41) were lower per added mutation (no mutation, 143±5 beats per minute; single mutation, 134±8 beats per minute; double mutations, 111±6 beats per minute; P<0.0001), and lower in symptomatic versus asymptomatic mutation carriers (122±10 versus 137±9 beats per minute; P<0.0001). Strong correlations between fetal heart rate and neonatal heart rate (r=0.700; P<0.001), and postnatal QTc (r=-0.762; P<0.001) were found. In a multivariable model, fetal genotype explained the majority of variance in fetal heart rate (-10 beats per minute per added mutation; P<1.0×10 -23). Arrhythmia symptoms and intrauterine β-blocker exposure each predicted -7 beats per minute, P<0.0001. Conclusions - In this study including 184 fetuses from 2 LQT1 founder populations, third trimester fetal heart rate discriminated between fetal genotypes and correlated with severity of postnatal cardiac phenotype. This finding strengthens the role of fetal heart rate in the early detection and risk stratification of LQTS, particularly for fetuses with double mutations, at high risk of early life-threatening arrhythmias. © 2015 American Heart Association, Inc.

Background and Aims: During the last decades, a multitude of different treatments for chronic liver disease have been introduced. New surveillance programs have been established to detect esophageal varices and liver cancer. The aims of our study were to assess whether the prognosis for patients hospitalized with liver diseases between 1969 and 2006 had improved and to study the differences in mortality and complications between patients with alcoholic liver disease and nonalcoholic liver diseases.Methods: We used the Swedish Hospital Discharge Register and Cause of Death Register at the National Board of Health and Welfare in Sweden between 1969 and 2006 to identify and follow-up a cohort of patients with liver disease according to the International Classification of Diseases-8, -9, and -10.Results: There were 36,462 patients hospitalized with alcoholic and 95,842 with nonalcoholic liver diseases. The main finding was that patients hospitalized with alcoholic liver disease had an increased mortality risk, compared to patient with nonalcoholic liver disease, 1.89 (1.85 to 1.92). In addition, the patients with alcoholic liver disease had an increased risk for esophageal varices and liver cancer. There was a reduced risk for hospitalization with esophageal varices for patients with nonalcoholic liver disease up to 1998.Conclusions: We found that the prognosis for patients hospitalized with chronic liver diseases had not improved. Patients with alcoholic liver disease have an increased risk of complications, which suggest that the disease is more aggressive and are in need of closer follow-up than other chronic liver diseases. © 2010 by the Research Society on Alcoholism.

Purpose: The aim of this study was to determine if mechanical bowel preparation (MBP) influences the intramucosal bacterial colony count in the colon. Materials and methods: Macroscopically normal colon mucosa was collected from 37 patients (20 with and 17 without MBP) who were undergoing elective colorectal surgery at three hospitals. The biopsies were processed and cultured in the same laboratory. Colony counts of the common pathogens Escherichia coli and Bacteroides: as well as of total bacteria were conducted. The study groups were comparable with regard to age, gender, antibiotics use, diagnosis and type of resection. Results: MBP did not influence the median colony count of E. coli, Bacteroides or total bacteria in our study. Conclusions: MBP did not affect the intramucosal bacterial count in this study. Further studies are suggested to confirm these findings. © Springer-Verlag 2009.

Background: Pregnancy in women with liver disease may increase the risk of fetal complication. Data on disease frequencies in children born to mothers with alcoholic liver disease do not exist, although we do know that prenatal alcohol exposure may affect the fetus negatively. Aims: The aim of this study was to assess the relative risk of neuropsychiatric diseases in children who were born to mothers with chronic liver diseases. Methods: We linked the Hospital Discharge Register, Medical Birth Register and Pharmaceutical Register in Sweden between 1969 and 2009 to identify women with liver disease. We identified their children, up to the age of 16 in the Medical Birth Register, born between 1973 and 2009. Between 2005 and 2009, we identified every prescription that was dispensed to these children. Results: We identified 5 124 children of mothers with alcoholic liver disease. There were 22 960 children of mothers with non-alcoholic liver disease. For controls, we used 10 sex-, age- and birthplace-matched children. There were more children born to mothers with alcoholic liver disease before the birth who had been dispensed antiepileptics (n = 11, RR = 3.2 (1.6-6.4)), neuroleptics (n = 7, RR = 5.0 (2.0-12.5)) and drugs to treat attention deficit hyperactivity disorders (n = 22, RR = 5.9 (3.7-9.4)) compared with sex-, age- and regionally adjusted controls. Children born to mothers with non-alcoholic liver disease had significantly increased risk of being dispensed drugs to treat attention deficit disorders (RR = 2.2 (1.8-2.6)). Conclusions: Mothers with alcoholic liver disease have increased risks of having children with severe neurological and psychiatric disorders. © 2012 John Wiley & Sons A/S.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a devastating inherited disorder characterized by episodic syncope and/or sudden cardiac arrest during exercise or acute emotion in individuals without structural cardiac abnormalities. Although rare, CPVT is suspected to cause a substantial part of sudden cardiac deaths in young individuals. Mutations in RYR2, encoding the cardiac sarcoplasmic calcium channel, have been identified as causative in approximately half of all dominantly inherited CPVT cases. Applying a genome-wide linkage analysis in a large Swedish family with a severe dominantly inherited form of CPVT-like arrhythmias, we mapped the disease locus to chromosome 14q31-32. Sequencing CALM1 encoding calmodulin revealed a heterozygous missense mutation (c.161A>T [p.Asn53Ile]) segregating with the disease. A second, de novo, missense mutation (c.293A>G [p.Asn97Ser]) was subsequently identified in an individual of Iraqi origin; this individual was diagnosed with CPVT from a screening of 61 arrhythmia samples with no identified RYR2 mutations. Both CALM1 substitutions demonstrated compromised calcium binding, and p.Asn97Ser displayed an aberrant interaction with the RYR2 calmodulin-binding-domain peptide at low calcium concentrations. We conclude that calmodulin mutations can cause severe cardiac arrhythmia and that the calmodulin genes are candidates for genetic screening of individual cases and families with idiopathic ventricular tachycardia and unexplained sudden cardiac death. © 2012 The American Society of Human Genetics.

Bone Marrow Transplantation | Year: 2011
We have investigated whether hematopoietic stem cell transplantation (HSCT) before the death of children with cancer has a long-term effect on the physical and psychological well-being of the parents. A nationwide questionnaire was sent out to all bereaved parents in Sweden who had lost a child due to a malignancy from 1992 to 1997. Self-reported levels of anxiety, depression and quality of life as well as overall psychological and physical well-being in bereaved parents of children who underwent HSCT were compared with bereaved parents whose children did not receive a transplant. Bereaved parents whose children underwent HSCT had, according to a visual digital scale, an increased relative risk (RR) of long-term anxiety (RR 1.5; 95% confidence interval (CI) 1.0-2.1), poor psychological well-being (RR1.3; 95% CI 1.1-1.5), low quality of life (RR 1.4; 95% CI 1.2-1.7) and poor physical health (RR 1.3; 95% CI 1.1-1.5), whereas the State-Trait Anxiety Inventory and The Göteborg Quality of Life Instrument were non-significantly increased (RR 1.3; 95% CI 0.8-2.3 and RR 1.7; 95% CI 0.9-3.3, respectively). The risks of these consequences were further augmented in case of multiple HSCT. We suggest that bereaved parents of children undergoing HSCT may be at greater risk of decreased psychological well-being than other bereaved parents of children with cancer. © 2011 Macmillan Publishers Limited.

The risk of spinal haematoma in patients receiving epidural catheters is estimated using routine coagulation tests, but guidelines are inconsistent in their recommendations on what to do when results indicate slight hypocoagulation. Postoperative patients are prone to thrombosis, and thromboelastometry has previously shown hypercoagulation in this setting. We aimed to better understand perioperative haemostasis by comparing results from routine and advanced tests, hypothesizing that patients undergoing major upper gastrointestinal surgery would be deficient in vitamin K-dependent coagulation factors because of malnutrition, or hypocoagulative because of accumulation of low molecular weight heparin (LMWH).Thirty-eight patients receiving epidural analgesia for major upper gastrointestinal surgery were included. We took blood at the time of preoperative epidural catheterization and at catheter withdrawal. Prothrombin time-international normalized ratio (PT-INR), activated partial thromboplastin time (aPTT) and platelet count (Plc) were analysed, and also albumin, proteins induced by vitamin K absence (PIVKA-II), rotational thromboelastometry (ROTEM), multiple electrode aggregometry (Multiplate) and activities of factors II, VII, IX, X, XI, XII and XIII.Postoperative coagulation was characterized by thrombocytosis and hyperfibrinogenaemia. Mean PT-INR increased significantly from 1.00.1 to 1.20.2 and mean aPTT increased significantly from 273 to 304s. Activity of vitamin K-dependent factors did not decrease significantly: FIX and FX activity increased. FXII and FXIII decreased significantly. Mean Plc increased from 21315310The increase in PT-INR may be caused by decreased postoperative FVII while the elevated aPTT may be caused by low FXII. The mild postoperative hypocoagulation indicated by routine tests is not consistent with thromboelastometry. The relevance of ROTEM and Multiplate in the context of moderately increased routine tests remains unclear. Trial registration number is not applicable since this is not a clinical trial.

The aim of our study was to investigate the risks of pregnancy and childbirth complications in women with autoimmune hepatitis compared to the population controls.In a nationwide cohort study of all pregnancies between 2006 and 2011 we investigated the risks of adverse pregnancy outcome in 171 births in women with diagnosed autoimmune hepatitis using the data from the Swedish Medical Birth and Patient Registries. Births to women without autoimmune hepatitis served as population controls (n = 576 642). Relative risks (RR) with 95% confidence intervals (CI) were calculated using Poisson regression models adjusting for potential confounders.Women with AIH had an increased risk of gestational diabetes (RR = 4.35, 95% CI 2.21-8.57), of preterm birth (RR = 3.21, 95% CI 1.97-4.92) and of low-birth-weight child (RR = 2.51, 95% CI 1.51-4.19). We found no statistically significant association between autoimmune hepatitis and pre-eclampsia, caesarean section, low 5-min Apgar score, small for gestational age birth, congenital malformation and neonatal mortality.Autoimmune hepatitis is a risk factor for adverse pregnancy outcomes. High quality prenatal and antenatal care is important for women with autoimmune hepatitis and their infants.

Background and purpose - Early postoperative mortality is relatively high after total hip arthroplasty (THA) that has been performed due to femoral neck fracture. However, this has rarely been investigated after adjustment for medical comorbidity and comparison with the mortality in an age-matched population. We therefore assessed early mortality in hip fracture patients treated with a THA, in the setting of a nationwide matched cohort study. Patients and methods - 24,699 patients who underwent THA due to a femoral neck fracture between 1992 and 2012 were matched with 118,518 controls. Kaplan-Meier survival analysis was used to calculate cumulative unadjusted survival, and Cox regression models were fitted to compute hazard ratios (HRs) and 95% confidence intervals (CIs), with adjustment for age, sex, comorbidity, and socioeconomic background. Results - 90-day survival was 96.3% (95% CI: 96.0-96.5) for THA cases and 98.7% (95% CI: 98.6-98.8) for control individuals, giving an adjusted HR of 2.2 (95% CI: 2.0-2.4) for THA cases compared to control individuals. Comorbidity burden increased in THA cases over time, but the adjusted risk of death within 90 days did not differ statistically significantly between the time periods investigated (1992-1998, 1999-2005, and 2006-2012). A Charlson comorbidity index of 3 or more, an American Society of Anesthesiologists (ASA) grade of 3 and above, male sex, an age of 80 years and above, an income below the first quartile, and a lower level of education were all associated with an increased risk of 90-day mortality. Interpretation - The adjusted early mortality in femoral neck fracture patients who underwent THA was about double that in a matched control population. Patients with femoral neck fracture but with no substantial comorbidity and an age of less than 80 years appear to have a low risk of early death. Patients older than 80 years and those with a Charlson comorbidity index of more than 2 have a high risk of early death, and such patients would perhaps benefit from treatment strategies other than THA, but this should be investigated further.
