Chertsey Outcome Score for Trauma: Development and validation of a newunifying patient reported outcome measure for orthopaedic trauma

Purpose: Lately there is an increasing tendency of using Patient Reported Outcome Measures (PROMs) as a final indicator of the outcome of many surgical treatments in orthopaedics and in other medical specialties. Currently there are many outcome scores in orthopaedics and most of them are site specific. In the contrary there is a lack of trauma specific outcome scores. Methods: We have designed a new PROM especially for orthopaedic trauma patients, in order to measure in what extent the patients manage to return to their pre-injury state. This score uses as baseline the preinjury status of the patient and has the aim to determine the percentage of rehabilitation after treatment for any injury. Results: A total of 60 Chertsey Outcome Score for Trauma (COST) questionnaires were gathered in our outpatients department. The participants were 57% male (aged 46.81 years ± 18.5 years) and the questionnaires collected at mean 10 months post-injury. A Cronbach''s Alpha value of 0.89 was identified for the whole construct. The three dimensions of the scale had good internal consistency as well (Cronbach''s Alpha test values 0.74, 0.84 and 0.81 for symptoms, function and mental status respectively). Strong/moderate correlation (Spearman''s Rho test 0.43e0.65) was observed between the respective physical/mental dimensions of the COST and SF-12v2 questionnaires. Conclusion: There is a need among the orthopaedic trauma society for a specific PROM of trauma. COST is a useful and easy to use tool for every trauma surgeon.     

Increased incidence of life-threatening ventricular arrhythmias in implantable defibrillator patients after the World Trade Center attack

OBJECTIVES: This study was designed to evaluate whether the destruction of the World Trade Center (WTC) on September 11, 2001 (9/11), led to an increased frequency of ventricular arrhythmias among patients fitted with an implantable cardioverter-defibrillator (ICD). BACKGROUND: The WTC attack induced psychological distress. Because ICDs store all serious arrhythmias for months, the attack provided a unique opportunity to compare pre- and post-9/11 frequencies of potentially lethal arrhythmias among ICD patients. METHODS: Two hundred consecutive ICD patients who presented for regularly scheduled follow-up to six affiliated clinics were recruited into this observational study. The electrograms stored in the ICDs for the three months before 9/11 and 13 months thereafter were scrutinized in a blinded manner (relative to date) for all ventricular tachyarrhythmias (tachycardia or fibrillation) triggering ICD therapy. RESULTS: The frequency of tachyarrhythmias increased significantly for the 30 days post-9/11 (p = 0.004) relative to all other months between May 2001 and October 2002. In the 30 days post-9/11, 16 patients (8%) demonstrated tachyarrhythmias, compared with only seven (3.5%) in the preceding 30 days, representing a 2.3-fold increase in risk (95% confidence interval 1.1 to 4.9; p = 0.03). The first arrhythmic event did not occur for three days following 9/11, with events accumulating in a progressive non-clustered pattern. CONCLUSIONS: Ventricular arrhythmias increased by more than twofold among ICD patients following the WTC attack. The delay in onset and the non-clustered pattern of these events differ sharply from effects following other disasters, suggesting that subacute stress may have served to promote this arrhythmogenesis.     

Gastrointestinal perforation in children due to blunt abdominal trauma in Hazara,Northern Pakistan

A retrospective study of 25 children with gastrointestinal perforation due to blunt abdominal trauma in a single region of Pakistan is presented. The age, sex, aetiology, site of perforation, abdominal and X-ray findings, associated injuries, surgical procedures and outcome were analysed. There were 20 boys and 5 girls: mean age was 10 years. The injuries were the result of road traffic accidents 12 (48%), falls 11 (44%) and 'struck by animals' two (8%). Associated injuries occurred in 19 (76%). On admission 20 (80%) patients had peritonitis while 18 (72%) had pneumoperitoneum. Mean time from trauma to admission was 10 hours and admission to operation was 5 hours. Ileum was the most common site of perforation. Simple closure was the most common surgical procedure. Complications occurred in nine (36%) patients--six (24%) died. Delay in presentation and operation was associated with increased morbidity and mortality. Frequent evaluation of the child and abdominal X-rays are still the important tools for early diagnosis of gastrointestinal perforation following blunt abdominal trauma.

Familial atrial fibrillation is a genetically heterogeneous disorder

OBJECTIVES: The aims of this study were to identify and characterize familial cases of atrial fibrillation (AF) in our clinical practice and to determine whether AF is genetically heterogeneous. BACKGROUND: Atrial fibrillation is not generally regarded as a heritable disorder, yet a genetic locus for familial AF was previously mapped to chromosome 10. METHODS: Of 2,610 patients seen in our arrhythmia clinic during an 18-month study period, 914 (35%) were diagnosed with AF. Familial cases were identified by history and medical records review. Four multi-generation families with autosomal dominant AF (FAF 1 to 4) were tested for linkage to the chromosome 10 AF locus. RESULTS: Fifty probands (5% of all AF patients; 15% of lone AF patients) were identified with lone AF (age 41 +/- 9 years) and a positive family history (1 to 9 additional relatives affected). In FAF 1 to 3, AF was associated with rapid ventricular response. In contrast, AF in FAF-4 was associated with a slow ventricular response and, with progression of the disease, junctional rhythm and cardiomyopathy. Genotyping of FAF 1 to 4 with deoxyribonucleic acid markers spanning the chromosome 10q22-q24 region excluded linkage of AF to this locus. In FAF-4, linkage was also excluded to the chromosome 3p22-p25 and lamin A/C loci associated with familial AF, conduction system disease, and dilated cardiomyopathy. CONCLUSIONS: Familial AF is more common than previously recognized, highlighting the importance of genetics in disease pathogenesis. In four families with AF, we have excluded linkage to chromosome 10q22-q24, establishing that at least two disease genes are responsible for this disorder.
