RESUMEN
BACKGROUND: The discharge letter is a key component of the communication pathway between the hospital and primary care. Accuracy and timeliness of delivery are crucial to ensure continuity of patient care. Electronic discharge summaries (EDS) and prescriptions have been shown to improve quality of discharge information for general practitioners (GPs). The aim of this study was to evaluate the effect of a new EDS on GP satisfaction levels and accuracy of discharge diagnosis. METHODS: A GP survey was carried out whereby semi-structured interviews were conducted with 13 GPs from three primary care centres who receive a high volume of discharge letters from the hospital. A chart review was carried out on 90 charts to compare accuracy of ICD-10 coding of Non-Consultant Hospital Doctors (NCHDs) with that of trained Hopital In-Patient Enquiry (HIPE) coders. RESULTS: GP satisfaction levels were over 90 % with most aspects of the EDS, including amount of information (97 %), accuracy (95 %), GP information and follow-up (97 %) and medications (91 %). 70 % of GPs received the EDS within 2 weeks. ICD-10 coding of discharge diagnosis by NCHDs had an accuracy of 33 %, compared with 95.6 % when done by trained coders (p < 0.00001). CONCLUSION: The introduction of the EDS and prescription has led to improved quality of timeliness of communication with primary care. It has led to a very high satisfaction rating with GPs. ICD-10 coding was found to be grossly inaccurate when carried out by NCHDs and it is more appropriate for this task to be carried out by trained coders.

BACKGROUND: Laparoscopic adrenalectomy is an attractive alternative to the traditional open approach in the surgical excision of an adrenal gland. It has replaced open adrenalectomy in our institution and we review our experience to date. METHODS: All cases of laparoscopic adrenalectomies in our hospital over eight years (from 2001 to May 2009) were retrospectively reviewed. Patient demographics, diagnosis, length of hospital stay, histology and all operative and post-operative details were evaluated. RESULTS: Fifty-five laparoscopic adrenalectomies (LA) were performed on 51 patients over eight years. The mean age was 48 years (Range 16-86 years) with the male: female ratio 1:2. Twenty-three cases had a right adrenalectomy, 24 had a left adrenalectomy and the remaining four patients had bilateral adrenalectomies. 91% were successfully completed laparoscopically with five converted to an open approach. Adenomas (functional and non functional) were the leading indication for LA, followed by phaeochromocytomas. Other indications for LA included Cushing's disease, adrenal malignancies and rarer pathologies. There was one mortality from necrotising pancreatitis following a left adrenalectomy for severe Cushing's disease, with subsequent death 10 days later. CONCLUSION: Laparoscopic adrenalectomy is effective for the treatment of adrenal tumours, fulfilling the criteria for the ideal minimally invasive procedure. It has replaced the traditional open approach in our centre and is a safe and effective alternative. However, in the case of severe Cushing's disease, laparoscopic adrenalectomy has the potential for significant adverse outcomes and mortality.

Mucinous cystadenomas of the appendix are rare, with significant malignant potential [Lo and Sarr in Hepatogastroenterology 50(50):432-437, 2003]. Carcinoid tumours are similarly uncommon, rarely occurring in Meckel's diverticula but are still the commonest tumour of Meckel's diverticulae [Nies et al. in Dis Colon Rectum 35(6):589-596, 1992; Modlin and Lye in Cancer 97(4):934-959, 2003; Sutter et al. in Schweiz Med Wochenschr Suppl 89:20S-24S, 1997; Weber and McFadden DW in J Clin Gastroenterol 11(6):682-686, 1989]. A 77-year-old woman presented to our clinic with a 6-week history of non-specific lower abdominal pain. A pelvic ultrasound showed an 8 × 3 × 2.5 cm mass in the right iliac fossa. Colonoscopy and CT confirmed this mass and also revealed a left colonic tumor. At laparotomy, three tumours were identified; in the appendix, a Meckel's diverticulum, and the descending colon. A subtotal colectomy and diverticulectomy were performed. Histology confirmed a T3N0 Dukes B colonic adenocarcinoma, a carcinoid of Meckel's diverticulum and a mucinous adenoma of the appendix. The patient is tumor free to date, 5 years after presentation. The presence of three synchronous tumours of different histological origin in the gastrointestinal tract has not previously been described in the literature.

BACKGROUND: Pyogenic liver abscess is a rare but potentially serious condition. It has traditionally been treated by open drainage; however interventional radiology is now becoming the standard of care. METHODS: All cases of liver abscesses admitted to a tertiary hospital over thirteen years (1995-2007) were retrospectively reviewed. Patient demographics, length of hospital stay, predisposing factors as well as cultured organisms were evaluated. Imaging techniques as well as patient management were also recorded. RESULTS: There were 66 hospital admissions of 61 patients with liver abscesses, 0.032% (66/205,079) of the total hospital admissions for the time period. Mean age was 61 years (range 26-90 years), male (36/61) 59%: female (25/61) 41%. Average hospital stay was 23 days (Range 1-84 days) and there were no deaths. 39 of 61 patients (64%) had a single abscess (90% right lobe). 20 of 61 patients (33%) had undergone a recent intra-abdominal procedure. Escherichia coli (10/61) and Enterococci (8/61) were the most frequent organisms isolated. Radiological intervention was performed in 50 of 61 (82%, 51% ultrasound and 31% CT guided). 9 of 61 (15%) were managed conservatively, while one case was managed surgically and another with endoscopic sphincterotomy and stent placement. CONCLUSIONS: Pyogenic liver abscesses are uncommon, and while associated with significant morbidity and prolonged hospital stay, mortality is now rare. Radiological intervention and anti-microbial therapy are the mainstay of treatment, and operative intervention is now rarely required.

INTRODUCTION: AAA screening programmes have proven to be beneficial and cost effective worldwide for males greater than 65 years of age, with 4.9% males of 65-75 years of age having an un-diagnosed AAA at screening, resulting in a 42% reduction in the risk of rupture in an English population. This study assessed the incidence of AAA and risk factors for atherosclerosis in Irish males of 55-75 years. METHODS: From April 2006 to December 2007, males between the ages of 55 and 75 years, living within the catchment area of Blanchardstown Hospital were invited for AAA screening using duplex ultrasound and cardiovascular risk factor screening. RESULTS: 1.9% (17/904) of the study population had previously un-diagnosed aneurysms detected, with sizes ranging from 3.0 cm to 5.8 cm (0.6% in 55-65 years old (yo) and 4.2% in 65-75 yo, p<0.01). 33% (302/904) of patients had hyperlipidaemia, while 16% of those with a previous diagnosis of hyperlipidaemia, were inadequately controlled on the test date. 31% of patients had a single elevated blood pressure reading, meriting further investigation for possible hypertension. 3% (28/904) of all patients had a raised glucose levels which had not previously been identified and of those who had a previous history of DM, 46% had abnormal glucose levels. 16% of patients (93/573) were morbidly obese (BMI>30) and 64% (292/573) were overweight. CONCLUSION: The incidence of AAAs in 65-75-year-old men is similar to international figures. This study confirms that screening for hyperlipidaemia, hypercholesterolaemia, obesity and hypertension may be worthwhile in all males over 55 years, while AAA screening should be reserved for 65-75-year-old Irish males.

Primary appendiceal neoplasms are a rare clinical and pathological entity. We report a case of synchronous appendiceal tumours of different histological types which presented as a symptomatic palpable and radiologically apparent mass in the right iliac fossa. This case demonstrates the importance of pre-operative diagnosis of these neoplasms, as it may alter the surgical approach and obviate the need for additional surgery. Furthermore, some of the controversies associated with the management of an appendix mass in the elderly population are discussed.

BACKGROUND: Adult intussusception is an uncommon surgical presentation AIMS: We report a case of adult intussusception, review the literature and discuss the optimal management. METHODS: We describe a woman who presented with severe abdominal pain and a large supra-umbilical mass. Ileocolic intussception was confirmed on CT, and a laparotomy and en-bloc resection were carried out. Postoperatively she made an uneventful recovery. CONCLUSION: Adult intussusception is a rare clinical presentation. En-bloc resection should be the surgical treatment of choice in the majority of cases due to the high percentage of malignant lead points.

Gene therapy-induced expression of immunostimulatory molecules at tumor cell level may evoke antitumor immune mechanisms by recruiting and enhancing viability of antigen-processing cells and specific tumoricidal lymphocytes. The antitumor efficacy of a plasmid, coding for granulocyte-macrophage colony-stimulating factor (GM-CSF) and the B7-1 costimulatory immune molecule, delivered into growing solid tumors by electroporation was investigated.

RESUMEN
Many patients with various types of cancers have already by the time of presentation, micrometastases in their tissues and are left after treatment in a minimal residual disease state [Am J Gastroenterol 95(12), 2000]. To prevent tumour recurrence these patients require a systemic based therapy, but current modalities are limited by toxicity or lack of efficacy. We have previously reported that immune reactivity to the primary tumour is an important regulator of micrometastases and determinant of prognosis. This suggests that recruitment of specific anti-tumour mechanisms within the primary tumour could be used advantageously for tumour control as either primary or neo-adjuvant treatments. Recently, we have focused on methods of stimulating immune eradication of solid tumours and minimal residual disease using gene therapy approaches. Gene therapy is now a realistic prospect and a number of delivery approaches have been explored, including the use of viral and non-viral vectors. Non-viral vectors have received significant attention since, in spite of their relative delivery inefficiency, they may be safer and have greater potential for delivery of larger genetic units. By in vivo electroporation of the primary tumour with plasmid expressing GM-CSF and B7-1, we aim to stimulate immune eradication of the treated tumour and associated metastases. In this symposium report, we describe an effective gene based approach for cancer immunotherapy by inducing cytokine and immune co-stimulatory molecule expression by the growing cells of the primary tumour using a plasmid electroporation gene delivery strategy. We discuss the potential for enhancement of this therapy by its application as a neoadjuvant to surgical excision and by its use in combination with suppressor T cell depletion.

SUMMARY. Esophageal squamous carcinomas induce regional immune suppression in the domain of the tumor while the global immune system remains intact. We report a patient with a squamous esophageal carcinoma, who was discovered at esophagectomy to have paraesophageal lymph node metastases from a prostatic adenocarcinoma. No other sites of metastatic disease were identified. This supports the concept that regional immune suppression by esophageal squamous cancers facilitates growth of metastases in the local lymph nodes.

Oral administration of antigens induces antigen-specific systemic immune tolerance (Oral Tolerance). We postulate that the poorer prognosis of foregut cancers might, in part be explained by the systemic immune tolerizing effect of tumor specific antigens shed into and processed by the gut immune system thus conferring a growth advantage specific to individual cancers. Immunocompetent Balb/c mice were fed by gavage, either tumor tissue (JBS/CarB) in phosphate buffered saline (PBS) or PBS alone, daily for 14 days. On day 15 either subcutaneous tumors were induced or animals were immunized with cells in adjuvant. JBS tumors appeared earlier and grew faster in the JBS tumor fed mice than in either the PBS (P = 0.025) or CarB (P = 0.168) fed animals. The delayed type hypersensitivity response in tolerized mice was significantly abrogated (P < 0.01) compared to controls. These experiments demonstrate antigen specific oral immune tolerance for tumors, which is reflected in a faster growth rate and impaired delayed type hypersensitivity response. Similar mechanisms may be operational in human esophagogastric malignancy and may in part explain their poorer outcome.
