Abstract
INTRODUCTION Whilst inherited medullary thyroid cancer has been extensively reported, familial non-medullary thyroid cancer is a rare and less well described clinical entity. Familial forms of the disease demonstrate more aggressive features than sporadic non-medullary thyroid cancer. PRESENTATION OF CASE A 54 year old lady was referred with globus on a background of a longstanding goitre. Three first degree relatives had a history of non-medullary thyroid carcinoma. Investigations revealed a papillary thyroid carcinoma and the patient proceeded to total thyroidectomy and ipsilateral Level VI neck dissection, followed by adjuvant radioiodine ablation. DISCUSSION Familial papillary thyroid carcinoma syndrome is defined as three or more first degree relatives diagnosed with the disease in the absence of other known associated syndromes. It is often associated with the presence of benign thyroid disorders, and is characterised by the early onset of multi-focal bilateral locally advanced tumours. CONCLUSION Familial papillary thyroid cancer is a rare clinical entity but should be considered where ≥3 first degree relatives are diagnosed with non-medullary thyroid cancer. It is necessary to exclude other familial tumour syndromes to make the diagnosis. It demonstrates more aggressive features with higher rates of local recurrence than its sporadic counterpart, and therefore mandates more aggressive management than might otherwise be indicated. Screening of first degree relatives should be considered. SUMMARY The case of a 54 year old female diagnosed with familial non-medullary thyroid carcinoma is reported.

Abstract
AIM There is debate about whether the traditional three-tiered grading of anal intraepithelial neoplasia (AIN) should be replaced by a more reproducible two-tiered system. In this study, we review our experience with AIN to determine the most suitable classification system. METHOD We performed a retrospective review of all histological reports over a 19 year period. All specimens were graded on haemataloxin and eosin appearance and those with dysplasia had immunohistochemistry for p16 and Ki67 performed. RESULTS Cases included 25 condyloma acuminata, 11 dysplastic cases and 24 invasive squamous cell carcinomas. On review, 18 were classified as condyloma acuminata without dysplasia. Seven had AIN I, five had AIN II and six had AIN III when using a three-tiered system. All cases classified as dysplastic (n = 18) showed an increased proliferation index as measured by Ki67. p16 positivity was seen in all AIN III, two AIN II and none of the AIN I cases. Recurrence was not observed in any of the AIN I cases. Five of eleven AIN II and AIN III cases recurred or persisted at a similar, higher or lower grade. Both of the AIN II cases which recurred or persisted were p16 positive. None of the AIN II cases that were p16 negative recurred. Three of the p16-positive AIN III cases did not recur. None of the 18 AIN cases progressed to carcinoma. CONCLUSION The findings support the slow progression of AIN as described in the literature. In our small series, a two-tiered system with further subclassification of the traditional AIN II group using p16 appears to be clinically useful.

Abstract
We report a case of Castleman's Disease (CD), hyaline vascular subtype involving the biliary tract with obstruction. A 43 year old man presented with a 5 week history of abdominal and back pain with biliary obstructive symptoms. He was jaundiced with persistently high LFTs. Radiological investigation revealed a stricture in the extrahepatic biliary tract. The clinical impression at the time was of sclerosing cholangitis with bile duct cholangiocarcinoma. A Whipple's procedure was performed. Histology and immunohistochemistry supported the histologic diagnosis of CD of hyaline vascular subtype. There was no evidence of disease elsewhere and the patient was disease free after a 6 year follow-up. Our case describes the hyaline vascular subtype of CD, a relatively rare disease occurring in a previously undescribed location.

Abstract
Fluorodeoxyglucose (FDG) whole body positron emission computed tomography (PET-CT) detects clinically occult malignancy. The aim of this study was to assess the prevalence and significance of focal thyroid 18F - fluorodeoxyglucose uptake. A retrospective review of all patients who had FDG PET-CT examinations, in a single tertiary referral centre was performed. PET scan findings and the final pathological diagnosis were collated. 2105 scans were reviewed. Focal uptake was identified in 35 (1.66%) patients. Final surgical histology was available on eight patients, which confirmed papillary carcinoma in four (20%) patients and lymphoma and metastatic disease in two patients respectively. This gave an overall malignancy rate in focal thyroid uptake of at least 33%. Thyroid incidentalomas occurred with a frequency of 2.13%, with an associated malignancy rate of at least 33% in focal thyroid uptake. The high malignancy rate associated with focal thyroid uptake mandates further investigation in medically fit patients.

Abstract
OBJECTIVE To explore the relationship between cannabis use and self-reported dimensions of psychosis in a population of university students presenting for any reason to primary care. METHOD One thousand and forty-nine students attending the Student Health Unit, National University of Ireland, Galway, completed self-report questionnaires on alcohol and substance misuse, non-clinical dimensions of psychosis [Community Assessment of Psychic Experiences (CAPE)], anxiety and depression [Hospital Anxiety and Depression Scale (HADS)]. Association of cannabis use with psychiatric symptoms was explored whilst controlling for confounds. RESULTS More frequent cannabis use was independently associated with greater intensity of positive, negative and depressive psychotic symptoms. The earlier the age of onset of cannabis use, the more positive psychotic symptoms were reported. CONCLUSION These findings support the hypotheses that cannabis use increases the risk of developing psychotic symptoms and that this risk is further increased in those individuals who use cannabis more heavily and commence it at a younger age.

Abstract
Ad5/35 chimeric oncolytic viruses (OVs) have earlier been shown to increase the level of vector transduction, intratumoral virus spread and survival in a number of xenograft models when compared with Ad5-based viruses. Because radiation and chemotherapy are the current standards of care for most cancer indications, Ad5/35 OVs have been tested here in combination with either radiation or chemotherapy in a head and neck cancer (HNC) xenograft model to determine whether such combination therapies enhance the potency of the virus, thereby leading to a greater therapeutic effect. In mice treated with either Ad5 OV (OV-5) or Ad5/35 chimeric OV (OV-5T35H), there was a delay in tumor progression compared with animals treated with phosphate-buffered saline (PBS) alone. When Ad5/35 chimeric OV and radiation were used in combination, there was a further delay in tumor progression, which resulted in a significant increase in the mean survival time of tumor-bearing mice compared with Ad5/35 or Ad5 OV monotherapy or to the combination of Ad5 OV with radiation, which was significantly less potent (P<0.0001) compared with the Ad5/35 OV plus radiation combination. Similarly, a combination of Ad5/35 chimeric OV with cisplatin significantly delayed tumor progression compared with Ad5/35 OV or Ad5 OV virus alone or with the combination of Ad5 virus with cisplatin (P<0.01). In summary, the combination of the potent Ad5/35 chimeric OV with either radiation or chemotherapy leads to significantly increased survival of mice bearing highly aggressive tumors, and may therefore offer an effective treatment strategy for patients with difficult to treat HNC.

Abstract
BACKGROUND Locally advanced rectal cancer is frequently treated with neoadjuvant chemoradiotherapy to reduce local recurrence and possibly improve survival. The tumor response to chemoradiotherapy is variable and may influence the prognosis after surgery. This study assessed tumor regression and its influence on survival in patients with rectal cancer treated with chemoradiotherapy followed by curative surgery. METHODS One hundred twenty-six patients with locally advanced rectal cancer (T3/T4 or N1/N2) were treated with chemoradiotherapy followed by total mesorectal excision. Patients received long-course radiotherapy (50 Gy in 25 fractions) in combination with 5-flourouracil over 5 weeks. By means of a standardized approach, tumor regression was graded in the resection specimen using a 3-point system related to tumor regression grade (TRG): complete or near-complete response (TRG1), partial response (TRG2), or no response (TRG3). RESULTS The 5-year disease-free survival was 72% (median follow-up 37 months), and 7% of patients had local recurrence. Chemoradiotherapy produced downstaging in 60% of patients; 21% of patients experienced TRG1. TRG1 correlated with a pathological T0/1 or N0 status. Five-year disease-free survival after chemoradiotherapy and surgery was significantly better in TRG1 patients (100%) compared with TRG2 (71%) and TRG3 (66%) (P = .01). CONCLUSION Tumor regression grade measured on a 3-point system predicts outcome after chemoradiotherapy and surgery for locally advanced rectal cancer.

Abstract
In designating the thymic origin of the cells, the T in T cell seems simple enough, and the impressive unfolding of how the differentiation and selection of conventional CD4 and CD8 T cells are supported by the uniquely capable thymic stroma seems prima facie to leave little left to uncover. But, as the initial uncovering of T-cell receptor (TCR) gamma-chain genes forewarned, there are myriad "unconventional T cell" subtypes whose development is not easily explained by current understanding. Such cells, either TCR alphabeta(+) or TCR gamma delta(+), rarely express either CD4 (a coreceptor for major histocompatibility complex (MHC) II) or CD8 alphabeta (a coreceptor for MHC I).(2) Instead, they are CD4, CD8 double-negative (DN) or express a homomeric CD8 alpha alpha molecule. However, rather than being mere fringe players, worthy only of "page 2, column 3,"(3) these unconventional T cells compose a substantial fraction of perhaps the most abundant and most active T cells in the body--the intraepithelial lymphocytes (IELs)--that populate several body surfaces, including the gut. There, they seemingly contribute to the physiologic homeostasis that embraces epithelial integrity, the measured immune response to commensals, and the adaptive tolerance toward self-antigens. When this homeostasis is disrupted, IELs may also contribute to inflammatory and wound-healing responses. Given this, a strong interest in their origin is appropriate.

Abstract
INTRODUCTION Referral to colposcopy following a single mildly dyskaryotic smear is becoming more widely recommended in the developed world. This has workload and cost implications. AIM To investigate if stratification of mildly dyskaryotic smears by age group might allow selection of populations that could be followed by repeat cytology initially. METHODS The study set was of all women with a diagnosis of dyskaryosis between July 2004 and June 2005 in an opportunistic screening programme. The dyskaryosis was divided into high grade (moderate and severe) and low grade and ratios of high to low grade were calculated for age groups. The age intervals were under 20 years, and every 5 years from 20 to 54 years. RESULTS In the study period, a total of 34 180 cervical smears were examined. Of these, 2326 women were diagnosed with dyskaryosis, (1566 (67%) low grade, 760 (33%) high grade) in the given age groups. This gave an overall ratio of high grade to low grade of 1:2. Ratios of high-grade dyskaryosis to low-grade dyskaryosis stayed relatively constant throughout the age intervals from 20 to 54 years of age, Pearson correlation coefficient 0.91, p = 0.0014. CONCLUSION The ratios of incidences of grades of dyskaryosis remained constant throughout the age intervals suggesting that selective patterns of referral to colposcopy based on patient's age at diagnosis of mild dyskaryosis are not applicable.

Abstract
OBJECTIVE Large loop excision of the transformation zone (LLETZ) has become standard of care in the management of cervical squamous neoplasia and with cone biopsy glandular intraepithelial neoplasia. Controversy remains about the long-term effects of this traumatic procedure. The aim of this study was to count and compare the number of endocervical glandular cell groups in pre- and post-LLETZ cervical preparations using liquid-based cytology to establish a cyto-morphological correlate of destruction of the transformation zone. METHODS The cytology/histology correlation audit records of the Cytopathology Department of St Luke's Hospital in 2003 and early 2004 were used to select patients with a cytological diagnosis of high grade dyskaryosis followed by LLETZ. Only those cases with post-LLETZ cytological follow-up were selected. Cases using conventional smears were excluded. One hundred and twenty slides (60 pairs of slides) in total were retrieved. The cases underwent review and all groups of >3 glandular cells in each slide were counted by AM while blinded as to whether smears were pre- or post-LLETZ. Medians were compared using a Mann-Whitney U-test. RESULTS The median number of groups of endocervical glandular cells of the pre-treatment group was 5.5 and of the post-treatment group was 2.0. There were significantly fewer endocervical glandular cell groups in the post-LLETZ population (P = 0.03). CONCLUSIONS The number of endocervical glandular groups in cervical cytological preparations decreases significantly following LLETZ procedure. This suggests that cytological follow-up may not be as useful in glandular neoplasia cases. Few or absent glandular cell groups in post-LLETZ preparations may have implications for adequacy assessment.

Abstract
BACKGROUND Endometriosis depends on oestrogenic stimulation for its continued growth, accounting for its prevalence during reproductive years. There is doubt among clinicians regarding its existence in postmenopausal women in the absence of exogenous or endogenous sex hormones. We postulated that endometriosis occurring in postmenopausal women would show a different morphologic and immunohistochemical profile to the disease occurring in premenopausal women. METHODS We reviewed the most recent 100 cases of endometriosis in our department plus all cases occurring in women aged > or =50 dating back to 1999. Cases were divided into <50 (n = 91), 50-59 (8) and > or =60 (6), and analysed for extent of disease, proportions of epithelium and stroma, and amount of haemorrhage. Immunohistochemistry for oestrogen receptor (OR), progesterone receptor (PR) and CD10 was performed and analysed on all cases aged > or =50 and on controls <50. RESULTS There was statistically less disease in older women when cases occurring in the cervix and in scars were excluded (p = 0.0191). There was no statistical difference in the proportions of epithelium or stroma, but there was a statistical difference in the amount of haemorrhage (p = 0.0154) with older women showing less haemorrhage. There was no significant difference in immunohistochemical profile. CONCLUSIONS Endometriosis does occur in postmenopausal women but is less common, is present in smaller volumes, and is less active. It has the same immunohistochemical profile as the disease occurring in premenopausal women and we infer from this that it has the potential to reactivate given the appropriate stimulation.

Abstract
OBJECTIVES The ThinPrep test was introduced into our institution on a phased basis over 3 years between January 2002 and December 2004. This study set out to assess its effect on productivity (as measured by output of cases per medical scientist per day) during the changeover period. Numbers of high and low-grade lesions and of unsatisfactory slides were also monitored. METHODS The percentage conversion from conventional preparation to liquid-based cytology (LBC) and output of cases per medical scientist per day were calculated from our database at 6-month intervals. The average backlog, average number of cases received per month and percentage of unsatisfactory and abnormal cases were calculated similarly. RESULTS Over the study period 92 084 cases were received. The percentage of cases using ThinPrep increased: from 9% in January 2002 to 73% in December 2004. During the study there was an increase in output from 17.0 to 22.3 cases per medical scientist per day, representing a 31% improvement at 73% conversion. Numbers of unsatisfactory cases decreased substantially and the numbers of low and high-grade diagnoses were relatively constant. CONCLUSIONS The change to ThinPrep has improved productivity and decreased the number of unsatisfactory cases. There was no adverse effect on quality during the changeover.

Abstract
AIMS To standardize the pathological analysis of total mesorectal excision specimens of rectal cancer following neoadjuvant chemoradiotherapy for locally advanced disease (T3/T4), including tumour regression. METHODS AND RESULTS Standardized dissection and reporting was used for 60 patients who underwent total mesorectal excision following long-course chemoradiotherapy. Tumour regression was scored by two pathologists (K.S., D.G.) using both an established 5-point tumour regression grade (TRG), and a novel 3-point grade. Both scores were evaluated for interobserver variability. A complete or near-complete pathological response (3-point TRG 1) was found in 10 patients (17%). Using the 5-point TRG, there was good agreement between both pathologists (kappa = 0.64). Using the 3-point grade, agreement was excellent (kappa = 0.84). No disease recurrence has been reported in patients with a complete, or near complete pathological response (3-point TRG 1), after a mean follow-up of 22 months. CONCLUSION Tumour regression grade is a useful method of scoring tumour response to chemoradiotherapy in rectal cancer. TRG 1 and 2 can be regarded as a complete pathological response (ypT0). A modified 3-point grade has the advantage of better reproducibility, with similar prognostic significance.

Abstract
OBJECTIVES Recent National Health Service Cervical Screening Programme (NHSCSP) guidelines suggest referral for colposcopy following an initial result of mild dyskaryosis. The aim of this study was to investigate if the number of dyskaryotic cells counted on an initial ThinPrep cervical sample showing mild dyskaryosis has predictive value. METHODS Cases of mild dyskaryosis on ThinPrep cervical samples from 2002 were retrieved from the cytology department records of St Luke's Hospital. A total of 123 sequential cases with a first-time result of mild dyskaryosis on ThinPrep slides with follow-up cytology available in the same institution were identified. While blinded to outcome, the number of dyskaryotic cells was counted in each case. Follow-up colposcopy/histology information was retrieved where indicated. The number of dyskaryotic cells counted on each slide was collated with outcome data. RESULTS Of the 123 cases, six women were lost to follow-up. Seventy-three had a negative outcome, 27 had a low-grade outcome and 17 had a high-grade outcome. Only one of 17 high-grade outcome cases had < or = 15 dyskaryotic cells on the initial slide. The distribution of women with a negative/low-grade outcome and those with a high-grade outcome with >15 and < or = 15 dyskaryotic cells on the initial slide was tested using a chi-square test (P = 0.008). The negative predictive value for a high-grade outcome when < or = 15 dyskaryotic cells were present on the initial slide was 97.7%. CONCLUSION The number of dyskaryotic cells on ThinPrep slides showing mild cervical dyskaryosis has predictive value. The number of dyskaryotic cells may be used to select women suitable for cytological rather than colposcopic follow-up.

Abstract
During a recent discussion on classification of cervical cytology, the introduction of a 'Borderline Nuclear Change - High Grade Dyskaryosis Not Excluded' (BNCH) category was proposed. BNCH cases diagnosed prospectively were retrieved from laboratory records. Questionnaires were sent to referring practitioners regarding clinicopathological outcome. Cytopathological features resulting in the BNCH classification were recorded on slide review. A total of 103 reports on conventional cervical smears diagnosed as BNCH from 1999 to 2002 were retrieved, comprising 0.096% of 107 634 smears. Of 86/103 cases with clinical follow-up, CIN2 or worse was present in 30 (35%); 15 (17%) showed a borderline/low-grade abnormality and 41 (48%) were negative. No individual cytopathological feature was predictive of high-grade disease on follow-up. The yield of high-grade abnormalities on follow-up of BNCH supports the introduction of this terminology.
