RESUMEN
BACKGROUND: The overall incidence of colorectal cancer is decreasing in much of the world, yet the incidence in those under 50 years of age is increasing (early onset colorectal cancer (EOCRC)). The reasons for this are unclear. This study was undertaken to describe the clinical, pathological and familial characteristics of patients with EOCRC and their oncological outcomes and compare this with previously published data on late onset colorectal cancer (LOCRC). METHODS: A retrospective review of all patients diagnosed with EOCRC in Canterbury between 2010 and 2017 was conducted. Data was collected on demographics, family history, treatment, and oncologic outcomes. Kaplan-Meier survival curves were calculated to assess overall survival based on disease stage. RESULTS: During the study period (2010-2017) there were 3340 colorectal cancers diagnosed in Canterbury, of which 201 (6%) were in patients under 50 years (range: 17-49). Of these, 87 (43.3%) were female and 125 (62.2%) were aged between 40 and 49 years. 28 (13.9%) were associated with hereditary conditions. Of the 201 patients, 139 (69.2%) had rectal or left-sided cancers. 142 (70.6%) patients presented with either stage 3 or 4 disease and the 5-year overall survival by stage was 79.1% and 14.4%, respectively. CONCLUSION: EOCRC is increasing and usually presents as distal left sided cancers, and often at an advanced stage. They do not appear to have the common risk factors of family history or inherited pre-disposition for colorectal cancer. Planning by healthcare providers for this epidemiological change is imperative in investigating symptomatic patients under 50 and optimizing early detection and prevention.

BACKGROUND: Anterior glenohumeral instability occurs most commonly in those aged 15-29, with 72% of individuals younger than 22 years suffering recurrent episodes; collision athletes are at particular risk. In the setting of subcritical glenoid bone loss, arthroscopic Bankart repair is widely used despite concerns of recurrent dislocations when compared with open techniques. Furthermore, indications for bone-block procedures are evolving with the Latarjet procedure being favored amongst recent authors as a primary stabilization method in elite and contact athletes. OBJECTIVE: To determine the efficacy of open modified Bankart stabilization in treating anterior glenohumeral instability in young collision athletes. METHODS: This was a retrospective review of outcomes of consecutive patients aged 15-20 years who underwent unilateral or bilateral open stabilization for recurrent anterior glenohumeral instability over a 7-year period (2007-2015). The cohort was selected as recent literature suggests that this is the group with the highest redislocation rate and poorest outcomes. Outcome assessments included redislocation rate, return to sport, pain score, patient-related satisfaction scores, and the Western Ontario Shoulder Instability Index. RESULTS: A total of 60 patients (55 male: 5 female) of mean age 18 years (range: 15-20 years) were available for follow-up at 7 years. All but 3 were competitive athletes with 18 competing regionally and 9 internationally; rugby union and rugby league represent the most common sports. Fifty-five of 60 (92%) have returned to their desired level of sport with 62% of athletes returning to their previous level of competition sport and 1 retuning at a higher level. The mean postoperative pain score was 2.5/10. The mean time to return to play was 14 months (range: 5-48 months). Eight of 60 shoulders reported redislocation (13%), 7 of these being traumatic dislocations after return to high-impact sporting activities. At 7 years of follow-up, 4 of 60 shoulders (7%) had undergone revision surgery. CONCLUSION: Young collision athletes represent a challenging cohort of instability patients. This study of open modified Bankart in young collision sport athletes revealed excellent outcomes with 92% return to sport and a low revision rate. The results from this cohort rival those of arthroscopic repair. The open procedure described here in this 7-year series represents a robust, reliable technique that could be considered as an alternative to arthroscopic Bankart due to concern for recurrence, while avoiding potential morbidity and complication of bone-block procedures. There is still a role for the open modified Bankart procedure in treating traumatic anterior instability.

AIM: The risk of developing colorectal cancer (CRC) in Crohn's disease (CD) has been variably reported. Chronic inflammation is associated with an increased risk of neoplasia; variable outcomes in CD possibly reflect the heterogeneous nature of the disease. The aim of this work was to characterize the risk of CRC in a New Zealand population-based cohort of CD patients with colonic inflammation. METHOD: A review of all participants with CD in the population-based Canterbury Inflammatory Bowel Disease Study was conducted. Data on demographics, endoscopic surveillance, presence of dysplasia/neoplasia and oncological outcome were extracted. The age-adjusted standardized incidence ratio (SIR) was used to compare the incidence of CRC in the cohort with the incidence of CRC in the New Zealand population in 2006. RESULTS: Data on 649 patients with CD were collected. Four hundred and thirty-six participants (58% female) with ileocolonic or colonic CD were included for analysis. CRC was diagnosed in 13 patients (62% female). The median age at CRC diagnosis was 58.5 years, and the mean duration of CD prior to diagnosis of CRC was 20.4 years. When compared with the New Zealand population (using census data), the overall age-adjusted SIR was 4.1 (95% CI 2.4-7.1). CONCLUSION: This population-based cohort of patients with colonic CD shows a significantly increased risk of CRC compared with the general population. This is consistent with the colonic location of inflammation increasing the risk of neoplasia. Inclusion of patients with isolated upper gastrointestinal/ileal CD in similar studies may mask the truly increased risk for patients with long-standing colonic inflammation.

BACKGROUND: Failure rates of up to 20% have been reported after fasciotomy for chronic exertional compartment syndrome (CECS). There is some evidence that postoperative failure and complication rates are higher in the posterior compartments of the lower leg than the anterolateral compartments. Isolated compartment surgery may put patients at risk of requiring revision surgery because of the risk of developing posterior compartment disease. HYPOTHESIS: Isolated anterolateral fasciotomy for CECS, in the absence of posterior compartment symptoms, produces satisfactory functional outcomes. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Between 2006 and 2012, patients who had positive intracompartment pressure-testing findings and who underwent isolated anterolateral fasciotomy release for CECS were given a self-administered questionnaire. The minimum follow-up was 3 years. The questionnaire addressed time to return to sport and ongoing symptoms. A visual analog scale was used to assess pain during exercise before and after surgery (score: 0, no pain; 10, worst pain imaginable); overall satisfaction with the procedure was assessed as well. Of 31 eligible patients, 20 patients (36 legs operated on) were assessed. RESULTS: Postoperatively, 90% of participants returned to the same or higher level of sport. The mean pain score during exercise before surgery was 8.17, whereas it was 1.74 after surgery. The overall mean patient satisfaction score was 8.64. Only 1 leg (2.8%) went on to develop posterior compartment syndrome. CONCLUSION: Isolated anterolateral fasciotomy for CECS produced excellent functional outcomes. Our rate of recurrence was low compared with those found in the literature, and 90% of participants returned to their same or higher level of sport postoperatively.
