RESUMO
AIM: Significant recent changes in management of locally advanced rectal cancer (LARC) include preoperative staging, use of extended neoadjuvant therapies and minimally invasive surgery (MIS). This study was aimed at characterizing these changes and associated short-term outcomes. METHOD: We retrospectively analysed treatment and outcome data from patients with T3/4 or N+ LARC ≤ 15 cm from the anal verge who were evaluated at a comprehensive cancer centre in 2009-2015. RESULTS: In total, 798 patients were identified and grouped into five cohorts based on treatment year: 2009-2010, 2011, 2012, 2013 and 2014-2015. Temporal changes included increased reliance on MRI staging, from 57% in 2009-2010 to 98% in 2014-2015 (P < 0.001); increased use of total neoadjuvant therapy, from 17% to 76% (P < 0.001); and increased use of MIS, from 33% to 70% (P < 0.001). Concurrently, median hospital stay decreased (from 7 to 5 days; P < 0.001), as did the rates of Grade III-V complications (from 13% to 7%; P < 0.05), surgical site infections (from 24% to 8%; P < 0.001), anastomotic leak (from 11% to 3%; P < 0.05) and positive circumferential resection margin (from 9% to 4%; P < 0.05). TNM downstaging increased from 62% to 74% (P = 0.002). CONCLUSION: Shifts toward MRI-based staging, total neoadjuvant therapy and MIS occurred between 2009 and 2015. Over the same period, treatment responses improved, and lengths of stay and the incidence of complications decreased.

BACKGROUND: Centenarians are the fastest rising age group in Ireland. Hip fractures most commonly affect older adults and are associated with significant morbidity and mortality, as well as the financial cost of healthcare resources. Despite this, very little is known regarding hip fractures in centenarians. The aim of this study was to investigate our experience with hip fractures in this group and to record the cost of treating these fractures to identify both the social and economic impact these injuries impose on the health system. METHODS: The study was a retrospective data review at a major trauma centre. Nine proximal femoral fractures from June 2010-2016 were identified through a stepwise analysis of theatre data and patient notes. Time of death was recorded directly from patient records or by contacting the patient's general practitioner. With the assistance of the hospital finance department, individual inpatient costs were calculated using length of stay, theatre time and implant costs. RESULTS: Over the 7-year period we examined nine patients over 100 years of age were managed operatively for hip fractures with an average inpatient cost of 14,898. The mean age at the time of fracture was 101 years and 7 months. Eight of the patients were female and there was one male. Our inpatient, 30-day and 1-year mortality rate were 22, 22, and 71%. CONCLUSIONS: The 1-year mortality rate of any person aged 100 years or older is thought to be 67% for men and 59% for women. This suggests that the 1-year mortality rate of 71% in this current study is only slightly worse than the usual life expectancy of a person older than 100 years of age. Our data suggest that the extreme elderly should be offered operative management.

PURPOSE: To describe the clinical and CT imaging features of goblet cell carcinoid (GCC) neoplasm of the appendix. METHODS AND MATERIALS: A computer search of pathology and radiology records over a 19-year period at our two institutions was performed using the search string "goblet". In the patients with appendiceal GCC neoplasms who had abdominopelvic CT, imaging findings were categorized, blinded to gross and surgical description, as: "Appendicitis", "Prominent appendix without peri-appendiceal infiltration", "Mass" or "Normal appendix". The CT appearance was correlated with an accepted pathological classification of: low grade GCC, signet ring cell adenocarcinoma ex, and poorly differentiated adenocarcinoma ex GCC group. RESULTS: Twenty-seven patients (age range, 28-80 years; mean age, 52 years; 15 female, 12 male) with pathology-proven appendiceal GCC neoplasm had CT scans that were reviewed. Patients presented with acute appendicitis (n=12), abdominal pain not typical for appendicitis (n=14) and incidental finding (n=1). CT imaging showed 9 Appendicitis, 9 Prominent appendices without peri-appendiceal infiltration, 7 Masses and 2 Normal appendices. Appendicitis (8/9) usually correlated with typical low grade GCC on pathology. In contrast, the majority of Masses and Prominent Appendices without peri-appendiceal infiltration were pathologically confirmed to be signet ring cell adenocarcinoma ex GCC. Poorly differentiated adenocarcinoma ex GCC was seen in only a small minority of patients. Hyperattenuation of the appendiceal neoplasm was seen in a majority of cases. CONCLUSIONS: GCC neoplasm of the appendix should be considered in the differential diagnosis in patients with primary appendiceal malignancy. Our cases demonstrated close correlation between our predefined CT pattern and the pathological classification.

No cerebrospinal fluid (CSF) abnormalities are found in HIV-positive patients in long-term follow-up after standard syphilis treatment. Syphilis has been reported to have immunological effects on HIV infection and HIV is known to modulate both the manifestations of syphilis and the serological response to therapy. HIV-positive patients who had been diagnosed with and treated for syphilis prior to 2007 were identified. Patients were consented for lumbar puncture. Serum HIV viral load, CD4 count and CSF were recorded. Thirty-five patients with previously diagnosed and treated syphilis underwent lumbar puncture. Thirty-four patients had a normal neurological exam. Only one patient had an abnormal mean white cell count (10.7 cells per high-power field). The finding that those with previously diagnosed syphilis had normal CSF and clinical findings is reassuring and supports the practice of using standard syphilis therapy in HIV-positive patients.

Carpal tunnel release can be performed under general or local anaesthetic. However, many surgeons believe the upper arm tourniquet is not tolerated by the patient when awake. We use a forearm tourniquet for carpal tunnel decompression under local anaesthesia. The aim of this study is to assess patient tolerance of the technique. Between January 1st 1996 and December 31st 2000, 74 patients had carpal tunnel release performed using local anaesthesia. We sent a postal questionnaire to each, asking the patient to rate different aspects of the procedure. Fifty-eight patients replied (78% response). Forty-four of the respondents (76%) tolerated the tourniquet well, finding it to be 'no problem' or only 'mildly painful'. The same number reported they would prefer to have local anaesthesia again in the event of their requiring a similar operation on their hand. We believe carpal tunnel release using local anaesthetic and a forearm tourniquet is well tolerated by the patient.

Anterior plates are used to increase the initial stability of anterior cervical spine fusions; however, plating has been suggested to cause graft stress shielding, leading to reduced fusion rates. The objectives of this study were to quantify the effects of graft size and plating (static versus dynamic) and the role of the posterior elements on load transmission in anterior cervical fusion. A C5 corpectomy was performed on six human cervical spines (C3-C7). An instrumented height-adjustable graft and dynamic cervical plate were used to measure axial load transmission. Each specimen underwent axial compressive testing with dynamic and static plate configurations, optimal and undersized graft heights, and posterior elements intact and removed. Dynamic plating allowed significantly more load transmission by the graft, particularly in the undersized graft configuration. The posterior elements play a significant role in load transmission.

We prospectively studied the use of intercostal EMG monitoring as an indicator of the accuracy of the placement of pedicle screws in the thoracic spine. We investigated 95 thoracic pedicles in 17 patients. Before insertion of the screw, the surgeon recorded his assessment of the integrity of the pedicle track. We then stimulated the track using a K-wire pedicle probe connected to a constant current stimulator. A compound muscle action potential (CMAP) was recorded from the appropriate intercostal or abdominal muscles. Postoperative CT was performed to establish the position of the screw. The stimulus intensity required to evoke a muscle response was correlated with the position of the screw on the CT scan. There were eight unrecognised breaches of the pedicle. Using 7.0 mA as a threshold, the sensitivity of EMG was 0.50 in detecting a breached pedicle and the specificity was 0.83. Thoracic pedicle screws were accurately placed in more than 90% of patients. EMG monitoring did not significantly improve the reliability of placement of the screw.

OBJECTIVES: To report experience with transverse sacral fracture, an uncommon injury frequently associated with neurologic deficit, and to perform a meta-analysis of the literature in order to define the role of decompression for the management of sacral fractures. DESIGN: A review of 7 cases. SETTING: A university-affiliated tertiary care centre. PATIENTS: Seven patients with transverse fractures of the sacrum. The mean follow-up was 13 months. INTERVENTIONS: A review of the clinical data and a search of the literature for studies that reported on 4 or more patients with a transverse sacral fracture. MAIN OUTCOME MEASURES: Mechanism of injury, type of neurologic deficit and its management. RESULTS: The most common mechanism in the 7 study patients was a fall from a height. Six patients had neurologic deficits, mostly in the form of bowel or bladder disturbance. Five of these were treated with surgical decompression, and 4 of them had an improvement in neurologic function. The 7 original studies from the literature dealt with a total of 55 patients. As in the study patients, falls from a height and motor vehicle accidents predominated as the mechanisms of injury. In contrast to patients in this study, 20 of 48 patients in the literature review with neurologic deficits were treated conservatively. CONCLUSIONS: The outcomes in this study are similar to those reported in the literature. The place of surgical decompression for patients with neurologic deficit cannot be clearly determined from the evidence currently available.

Wiskott-Aldrich syndrome (WAS) is a rare inherited disorder characterised by thrombocytopenia, eczema, and immunodeficiency. Bone marrow transplantation (BMT) is a well-established modality of treatment now routinely used and often curative. We report the case of a boy who developed osteopenia and sustained multiple long-bone fractures over a 5-year period after bone marrow transplant for WAS. The femora and tibiae of both lower limbs were involved with a clinical presentation similar to osteogenesis imperfecta. After commencing calcitriol treatment at the age of 8 years, the patient has not sustained any further fractures. He is now 11 years old. Although short-term changes in bone metabolism after BMT have been documented, the occurrence of repeated fractures associated with osteopenia has not been previously reported.

We use a braided polyester suture in place of cerclage wire in tension band fixations. The objective of this study was to test the biomechanical properties of this technique. Sixteen cadaveric patellae were fractured and repaired by modified tension band fixation. Eight were fixed using eighteen gauge stainless steel wire as a tension band and eight using braided polyester. All specimens were subjected to tensile testing. Polyester was 75.0% as strong as wire. For dynamic testing, the patellae of seven cadaveric knees were fractured and then fixed with polyester tension bands. These were mounted in a device capable of extending the knees from 90 degrees to neutral against an applied force. None of the fixations failed. Three of the specimens fixed using 18 gauge stainless steel wire were compared with three fixed using polyester over 2000 cycles of knee flexion and extension. Polyester performed as well as wire. We conclude that polyester is an acceptable alternative to wire in tension band fixation.

We report four cases with six episodes of concurrent carpal and elbow fractures or dislocations. Few such combinations of injuries have been reported in the literature. We discuss the mechanism and management of such injuries and conclude that elbow injuries should be suspected in severe carpal injuries. Surgical treatment may be required in their management.

The recent increase in lawsuits against health care personnel makes it advisable that dietitians recognize the potential for legal liability as they practice their profession. Whatever the exact nature of a dietitian's daily duties, an awareness and understanding of the concepts governing the law of malpractice will enable him/her to minimize exposure to liability. To accomplish this, the dietitian should exercise at least a standard of care accepted as competence for the profession. By so doing, the dietitian can insure not only less exposure to malpractice suits, but also attainment of an important goal: delivery of high-quality care to patients.
