Abstract
Objective A quarter of all cardiac tumors are malignant, and most (~ 95%) are sarcomas. It is the most aggressive malignant cardiac tumor carrying the worst prognosis. Tumor involvement with the vital intracardiac structures makes it difficult for complete surgical resection. We aimed to study the role of complete surgical resection and its importance in long-term outcomes. Methods We analyzed published literature from 2002 to 2022 using PubMed. Cases reported adult, intracardiac sarcomas, and received surgical resections were included. We reviewed 132 published case reports, including and analyzed the following variables: demographics, clinical presentations, diagnostic imaging modality, the extent of surgical resection, pathological diagnosis, tumor location, postoperative chemo-radiation therapy, and follow-up (including re-operation, local and distant recurrence). Results A total of 135 patients are included from 132 articles. The mean age was 46.69 (18-86) and 76 patients were females. The main complaints were dyspnea (70%) and chest pain (32%). Performed investigations were transthoracic echocardiography (TTE) in 114/135 (84%), computer tomography (CT) scan 89/135 (66%), trans-esophageal echocardiography (TOE) 22%, and cardiac magnetic resonance imaging (MRI) 29%. The most common location was the atrium (left 46%, right 30%). Complete surgical resection was performed in 91 cases (67%), and frozen section was performed in 62 patients (43 positives). Incomplete resections were in 42 cases. Patients who underwent complete surgical resection had mean survival of 14.58 months and median of 10.5 months, compared to incomplete resection patients with 9.12 months and 6.5 months respectively. Conclusion Our review shows complete surgical resection results in better short- and long-term outcomes in intracardiac sarcoma patients. Furthermore, combining chemo-radiotherapy has additional benefits towards long-term survival.

Abstract
BACKGROUND Control computerized tomography (cCT) is routinely used in many cystectomy centres before the final treatment cycle in patients with muscle-invasive urinary bladder cancer (MIBC) undergoing neoadjuvant chemotherapy (NAC). This is for evaluating response or nonresponse to NAC treatment. In a real-world retrospective cohort, we intended to evaluate the frequency of changed individual treatment strategies following cCT and to investigate any discrepancies between cCT-results on nodal staging and final pN-stages. METHODS We performed a retrospective data-based, multicenter study of 242 MIBC-patients, staged cT2N0M0-cT4aN0M0, having undergone NAC and radical cystectomy (RC) between 2008 and 2019 at four Swedish cystectomy centres. Statistical analysis was performed using IBM SPSS statistics 26. RESULTS Overall, 139/242 patients were examined with cCT. Six patients were staged as progressive at cCT and 5/139 (3.6%) underwent a change of previously planned treatment strategy. 2/6 patients with suspected progression (33%) did not change strategy and underwent all preplanned NAC-cycles plus RC. Only 1/6 patients assigned as progressive at the cCT, showed progression in the postoperative pathology specimen. In total 133/139 patients were considered being without progress on cCT, yet 28/133 (21%) presented with nodal progression at postoperative pathology examinations. Only 1/29 patients with histopathologically verified nodal dissemination were detected with cCT, thus 28/29 (96.6%) with pN + were undetected. The sensitivity for cCT to predict pTNM was 17% CI [0%-64%] and the specificity was 78% CI [71%-86%]. CONCLUSIONS CCT prior to the final treatment cycle of NAC in MIBC, leads to a low percentage of treatment strategy changes and cCT cannot accurately predict pN-status.

Abstract
Background
Orthotopic heart transplantation is the most effective long-term therapy for end-stage heart disease. Denervation of transplanted heart with the loss of autonomic modulation, vasculopathy, utilization of immunosuppressant drugs, and risk of allograft rejection may result in change in the prevalence of arrhythmias in transplanted hearts.
Purpose
To describe the trends, distribution and the clinical impact of arrhythmias in transplanted hearts in a large nationwide population.
Methods
We queried the National Inpatient Sample with administrative codes. Cardiac transplant patients were identified using procedure ICD-9-CM codes 37.5 and 33.6. Common arrhythmias were extracted using appropriate validated ICD-9-CM codes. Statistical Analysis System (SAS) version 9.4 was used for analysis of data.
Results
There was a total of 30,020 hospitalizations of heart transplant recipients between 1999 and 2014 in the United States and 16342 (54.4%) of these had arrhythmias. The prevalence of total arrhythmias increased from 53.6% (n=1,158) in 1999 to 67.3% (n=1,575) in 2014. The most common arrhythmia was atrial fibrillation (26.83%) followed by ventricular tachycardia (22.86%) and the prevalence of individual arrhythmias is as shown in Figure 1.
Cardiogenic shock was higher in transplanted hearts with arrhythmias when compared with patients without arrhythmias (25.96% vs 18.18%; p<0.001). Transplant recipients with arrhythmias were also associated with an increased use of mechanical circulatory device (18.22% vs 12.67%, p<0.001). The use of implantable cardiac defibrillators and permanent pacemaker was also higher in the arrhythmia group (2.19% vs 0.63% and 40.43% vs 30.24% respectively, p<0.0001). However, there was no significant difference in inpatient mortality between transplant recipients with arrhythmias and without arrhythmias (7.72% vs 6.90%, p=0.225). Further, there was no significant difference in frequency of strokes between the groups (4.98% vs 5.08%; p=0.857).
The total hospital cost when adjusted for inflation was significantly higher in the arrhythmic patients, with an average cost of about $570,415±9,590 vs $439,707±8362 in patients without arrhythmias (p<0.0001). The mean length of hospitalization was 44.2±0.8 days in patients with arrhythmias compared to 33.9±0.8 days in patients without arrhythmias (p<0.0001).
Conclusion
A significant proportion of patients with heart transplant have cardiac arrhythmias and are associated with worse in-hospital outcomes of cardiogenic shock, increased length of stay, and cost of hospitalization. However, they are not associated with worse inpatient mortality.

Abstract
Abstract
Introduction
Cardiopulmonary exercise testing (CPET) has an established role in the clinical evaluation of exercise intolerance and in the risk stratification of patients with heart failure. There is limited data assessing its prognostic utility in the evaluation of patients with Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC). The predisposition of patients with ARVC for ventricular arrhythmias and sudden cardiac death has led to recommendations for exercise restrictions and limits our understanding of how the impairment in oxygen extraction and cardiac output impact disease progression and outcomes in these patients.
Purpose
We examined the association between CPET indices and event free survival (time to mortality or cardiac transplantation) in patients with Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC).
Methods
Patients with definite ARVC based on 2010 task force criteria and genetically positive were enrolled into our institutional ARVC registry. 43 patients underwent CPET and have been included in our analyses. Indications for testing included: Evaluation of exercise-induced palpitations/arrhythmias or syncope (37%), pharmacotherapy optimization (28%), heart failure evaluation (19%), and ARVC management decisions (16%). CPET data (peak oxygen consumption (pVO2), respiratory exchange ratio (RER), and ventilatory efficiency (VE/VCO2) were assessed in patients at time of initial evaluation. Median follow-up time was 4.9 years (IQR 9 years).
Results
126 patients were studied (age 43.7+ 15 yrs; 41% women; LVEF 57+ 11%; 15% with LVEF <50%) and 43 underwent CPET evaluation. 41 patients (95%) performed at near maximal effort (RER >1) and no fatal events were reported during testing. During the follow up period, the outcome (death or cardiac transplantation) occurred in 31 patients. On Kaplan Meier analysis, pVO2 ≤14 mL/kg/min was associated with worse outcomes (unadjusted p<0.001). Peak oxygen consumption (pVO2) ≤14 mL/kg/min and ventilatory efficiency (VE/VCO2) >34 were associated with shorter event free survival (HR 5.58, p=0.002 and HR 5.56 p=0.005, respectively). After adjusting for age, sex, and right ventricular function, the association between peak oxygen consumption (pVO2) and event free survival remained significant (p=0.02).
Conclusions
In patients with ARVC, peak oxygen consumption (pVO2) was a prognostic indicator of worse outcomes. Our findings suggest a potential role for pVO2 in disease surveillance and early assessment for advanced heart failure therapies.

Abstract
BACKGROUND Although guidelines exist for advanced and variant bladder cancer management, evidence is limited/conflicting in some areas and the optimal approach remains controversial. OBJECTIVE To bring together a large multidisciplinary group of experts to develop consensus statements on controversial topics in bladder cancer management. DESIGN A steering committee compiled proposed statements regarding advanced and variant bladder cancer management which were assessed by 113 experts in a Delphi survey. Statements not reaching consensus were reviewed; those prioritised were revised by a panel of 45 experts before voting during a consensus conference. SETTING Online Delphi survey and consensus conference. PARTICIPANTS The European Association of Urology (EAU), the European Society for Medical Oncology (ESMO), experts in bladder cancer management. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Statements were ranked by experts according to their level of agreement: 1-3 (disagree), 4-6 (equivocal), 7-9 (agree). A priori (level 1) consensus was defined as ≥70% agreement and ≤15% disagreement, or vice versa. In the Delphi survey, a second analysis was restricted to stakeholder group(s) considered to have adequate expertise relating to each statement (to achieve level 2 consensus). RESULTS AND LIMITATIONS Overall, 116 statements were included in the Delphi survey. Of these, 33 (28%) statements achieved level 1 consensus and 49 (42%) statements achieved level 1 or 2 consensus. At the consensus conference, 22 of 27 (81%) statements achieved consensus. These consensus statements provide further guidance across a broad range of topics, including the management of variant histologies, the role/limitations of prognostic biomarkers in clinical decision making, bladder preservation strategies, modern radiotherapy techniques, the management of oligometastatic disease and the evolving role of checkpoint inhibitor therapy in metastatic disease. CONCLUSIONS These consensus statements provide further guidance on controversial topics in advanced and variant bladder cancer management until a time where further evidence is available to guide our approach.

Abstract
Tissue‐resident memory T (TRM) cells are CD8+ T lymphocytes that reside in the tissues, including tumours. This T cell subset possesses a magnitude of cytotoxicity, but its epigenetic regulation has not been studied. Here, we investigate the impact of perforin DNA methylation in TRM cells and correlate it with their functional potential. Fifty‐three urothelial urinary bladder cancer (UBC) patients were recruited prospectively. The DNA methylation status of the perforin gene (PRF1) locus in TRM cells was investigated by pyrosequencing. Flow cytometry with ViSNE analysis and in‐vitro stimulation were used to evaluate TRM cell phenotypes. We discovered that tumour TRM cells have low DNA methylation in the PRF1 locus (32·9% methylation), which corresponds to increased numbers of perforin‐expressing TRM cells. Surprisingly, programmed cell death 1 (PD‐1) expression is high in tumour TRM cells, suggesting exhaustion. Following interleukin‐15 and T cell receptor stimulation, perforin and T‐bet expressions are enhanced, indicating that TRM cells from tumours are not terminally exhausted. Moreover, a high number of TRM cells infiltrating the tumours corresponds to lower tumour stage in patients. In conclusion, TRM cells from UBC tumours are epigenetically cytotoxic with signs of exhaustion. This finding identifies TRM cells as potential new targets for cancer immunotherapy.

Abstract
Recent studies indicate that chemotherapeutic agents may increase the anti-tumoral immune response. Based on the pivotal role of dendritic cells (DCs) in host tumour-specific immune responses, we investigated the effect of commonly used chemotherapeutic drugs dexamethasone, doxorubicin, cisplatin and irinotecan and glucocorticoids on monocyte-derived DCs (moDCs). Dexamethasone displayed the strongest inhibitory effect on DC differentiation. The effect of cisplatin and irinotecan was moderate, while only weak effects were noticed for doxorubicin. Surprisingly, when the functional consequence of chemotherapy-treated CD14(+) monocytes and their capacity to activate CD4(+) T responders cells were investigated, cisplatin-treated monocytes gave rise to increased T cell proliferation. However, dexamethasone, doxorubicin and irinotecan-pretreated monocytes did not stimulate any increased T cell proliferation. Further investigation of this observation revealed that cisplatin treatment during DC differentiation up-regulated significantly the interferon (IFN)-β transcript. By contrast, no effect was evident on the expression of interleukin (IL)-1β, tumour necrosis factor (TNF)-α, IL-6 or IFN-α transcripts. Blocking IFN-β attenuated the cisplatin-enhanced T cell proliferation significantly. In conclusion, cisplatin treatment enhanced the immune stimulatory ability of human monocytes, a mechanism mediated mainly by the increased production of IFN-β.

Abstract
CONTEXT New data regarding treatment of muscle-invasive and metastatic bladder cancer (MiM-BC) has emerged and led to an update of the European Association of Urology (EAU) guidelines for MiM-BC. OBJECTIVE To review the new EAU guidelines for MiM-BC with a specific focus on treatment. EVIDENCE ACQUISITION New literature published since the last update of the EAU guidelines in 2008 was obtained from Medline, the Cochrane Database of Systematic Reviews, and reference lists in publications and review articles and comprehensively screened by a group of urologists, oncologists, and a radiologist appointed by the EAU Guidelines Office. Previous recommendations based on the older literature on this subject were also taken into account. Levels of evidence (LEs) and grades of recommendations (GRs) were added based on a system modified from the Oxford Centre for Evidence-based Medicine Levels of Evidence. EVIDENCE SYNTHESIS Current data demonstrate that neoadjuvant chemotherapy in conjunction with radical cystectomy (RC) is recommended in certain constellations of MiM-BC. RC remains the basic treatment of choice in localised invasive disease for both sexes. An attempt has been made to define the extent of surgery under standard conditions in both sexes. An orthotopic bladder substitute should be offered to both male and female patients lacking any contraindications, such as no tumour at the level of urethral dissection. In contrast to neoadjuvant chemotherapy, current advice recommends the use of adjuvant chemotherapy only within clinical trials. Multimodality bladder-preserving treatment in localised disease is currently regarded only as an alternative in selected, well-informed, and compliant patients for whom cystectomy is not considered for medical or personal reasons. In metastatic disease, the first-line treatment for patients fit enough to sustain cisplatin remains cisplatin-containing combination chemotherapy. With the advent of vinflunine, second-line chemotherapy has become available. CONCLUSIONS In the treatment of localised invasive bladder cancer (BCa), the standard treatment remains radical surgical removal of the bladder within standard limits, including as-yet-unspecified regional lymph nodes. However, the addition of neoadjuvant chemotherapy must be considered for certain specific patient groups. A new drug for second-line chemotherapy (vinflunine) in metastatic disease has been approved and is recommended.

Abstract
CONTEXT New data regarding diagnosis and treatment of muscle-invasive and metastatic bladder cancer (MiM-BC) has emerged and led to an update of the European Association of Urology (EAU) guidelines for MiM-BC. OBJECTIVE To review the new EAU guidelines for MiM-BC. EVIDENCE ACQUISITION A comprehensive workup of the literature obtained from Medline, the Cochrane central register of systematic reviews, and reference lists in publications and review articles was developed and screened by a group of urologists, oncologists, and radiologist appointed by the EAU Guideline Committee. Previous recommendations based on the older literature on this subject were taken into account. Levels of evidence and grade of guideline recommendations were added, modified from the Oxford Centre for Evidence-based Medicine Levels of Evidence. EVIDENCE SYNTHESIS The diagnosis of muscle-invasive bladder cancer (BCa) is made by transurethral resection (TUR) and following histopathologic evaluation. Patients with confirmed muscle-invasive BCa should be staged by computed tomography (CT) scans of the chest, abdomen, and pelvis, if available. Adjuvant chemotherapy is currently only advised within clinical trials. Radical cystectomy (RC) is the treatment of choice for both sexes, and lymph node dissection should be an integral part of cystectomy. An orthotopic bladder substitute should be offered to both male and female patients lacking any contraindications, such as no tumour at the level of urethral dissection. Multimodality bladder-preserving treatment in localised disease is currently regarded only as an alternative in selected, well-informed, and compliant patients for whom cystectomy is not considered for clinical or personal reasons. An appropriate schedule for disease monitoring should be based on: a) natural timing of recurrence; b) probability of disease recurrence; c) functional deterioration at particular sites; and d) consideration of treatment of a recurrence. In metastatic disease, the first-line treatment for patients fit enough to sustain cisplatin is cisplatin-containing combination chemotherapy. Presently, there is no standard second-line chemotherapy. CONCLUSIONS These EAU guidelines are a short, comprehensive overview of the updated guidelines of (MiM-BC) as recently published in the EAU guidelines and also available in the National Guideline Clearinghouse.

Abstract
The management and prognostication of patients with urothelial carcinomas (UCs), the most common histological type of bladder cancer, is mainly based on clinicopathological parameters. Several markers have been proposed to monitor this disease, including individual cell cycle-related proteins such as p53, pRb, p16, p21 and p27. Other putative markers are the oncogene products of FGFR3 and the ErbB family, proliferation markers including Ki-67, Aurora-A and survivin and different components within the immune system. In this review, a total of 12 parameters were evaluated and their discriminatory power compared. It is concluded that, in single-marker analyses, the proliferation markers Ki-67, survivin and Aurora-A offer the best potential to predict disease progression since they were all able to demonstrate independent prognostic power in repeated studies. Markers related to the immune system (e.g. CD8+ cells, regulatory T cells and cyclooxygenase-2 expression) or oncogene products of the ErbB family and FGFR3 are less powerful predictors of outcome or have not been equally well studied. The cell cycle-related proteins p53, pRb, p16, p21 and p27 have been extensively studied, but their usefulness as single prognostic markers remains unclear. However, in multimarker analyses, these markers appear to add prognostic information, indicating that they may contribute to more accurate treatment of UC.

Abstract
Being the first lymph node to receive drainage from the tumour area, the sentinel node offers a unique possibility to obtain tumour‐reactive lymphocytes. We investigated antitumour immune responses in sentinel nodes from patients with bladder cancer, by assaying tumour‐specific proliferation and TCR Vβ repertoires. During tumour surgery, sentinel lymph nodes were identified by peri‐tumoural injection of blue dye. Fresh specimens of tumour, sentinel and nonsentinel lymph nodes were obtained, and single‐cell suspensions were prepared. Cells were assayed for reactivity against autologous tumour extract in [3H]‐thymidine incorporation assays and characterized by flow cytometry. Parallel analyses of the expression of Vβ gene families were performed with padlock probes, linear oligonucleotides which upon target recognition can be converted to circular molecules by a ligase. Probes were reacted with cDNA prepared from magnetically separated CD4+ cells, and the TCR repertoire was determined by hybridizing the products to oligonucleotide microarrays. Dose‐dependent proliferation in response to tumour extract could be detected in sentinel lymph nodes. Common clonal expansions were detected among tumour‐infiltrating lymphocytes and in sentinel lymph nodes. Nonsentinel lymph nodes displayed a divergent TCR Vβ repertoire. These results indicate an ongoing immune response against tumour antigens in sentinel nodes, draining urinary bladder cancer. Identification of sentinel lymph nodes makes it possible to obtain tumour‐reactive lymphocytes for use in adoptive immunotherapy.

Abstract
PURPOSE Transitional cell carcinoma (TCC) of the prostate/prostatic urethra is a risk factor for urethral recurrence after radical cystoprostatectomy for TCC. Using conventional sectioning techniques, prostate involvement (prostatic urethra, acini, ducts and/or stroma) has been detected in a range of 10-20% of the patients, whereas transversal whole mount sectioning has revealed 43 % prostate involvement in two reported series. Due to different mechanisms of prostate involvement (intraurethral, extravesical and direct overgrowth into the prostatic stroma), preoperative transurethral biopsies of the prostate might not accurately determine such involvement. In this study we examine the prostate using a longitudinal whole mount sectioning technique, correlate TCC of the prostate with the characteristics of the bladder tumour and, thus, validate the preoperative transurethral resection biopsies. MATERIAL AND METHODS Patients scheduled for cystoprostatectomy or cystoprostatourethrectomy were investigated by preoperative resection biopsies from the prostatic urethra and mapping of the bladder. The cystectomy specimen was fixated with the bladder filled with formalin, and the prostate and bladder neck examined using longitudinal whole mount sectioning. RESULTS In 13 of the 43 (30%), patients TCC was identified in the prostate. Of these 13 patients, 9 had been identified in the preoperative resection biopsies from the prostatic urethra. Of the patients with prostatic involvement, 46% had carcinoma in situ (Cis) in the bladder neck/trigone and 38% had multifocal Cis in the bladder. Comparing this to the group of patients without prostatic involvement, the respectively figures are 20% and 23%. A tumour in the trigone, either invasive or Cis, was detected in 5/13 patients with prostatic involvement as compared to one patient (3%) without TCC of the prostate. Multiple bladder tumours were more common in patients with prostatic involvement and were larger (3.2 cm compared to 2.2 cm). CONCLUSIONS Preoperative resection biopsies from the prostatic urethra do not always detect TCC in the prostate. Cis in the bladder neck/trigone or multifocal and multiple bladder tumours could be risk factors for prostate involvement of TCC.

Abstract
PURPOSE Lymph node status is one of the most important prognostic factors in muscle-invasive bladder cancer. The extent of lymphadenectomy performed in conjunction with cystectomy and the question as to whether this is a staging or therapeutic intervention are matters of discussion. The aim of this study was to evaluate the sentinel node (SN) concept and to correlate findings with tumour status in excised regional lymph nodes. MATERIAL AND METHOD 26 patients scheduled for cystectomy were investigated with preoperative lymphoscintigraphy, peroperative dye detection (Patent Blue) and dynamic lymphoscintigraphy (Nanocoll or Albures 50 MBq/ml). The substances were injected adjacent to the tumour in the detrusor muscle. RESULTS Sentinel nodes were detected in 21 of the 26 of the investigated patients. 7/21 SN were located outside the obturator fossa. Of the eight patients with lymph node metastasis, five displayed metastasis in lymph nodes outside the obturator fossa. There was one false negative SN in a patient with multifocal tumour, while in the other seven patients with lymph node metastasis, these were detected in the SN. CONCLUSION Sentinel node detection is possible in most cases of bladder cancer scheduled for cystectomy. The significance of utilizing this method to detect lymph node metastasis outside the obturator fossa warrants further investigation.

Abstract
PURPOSE We examined the possibility for detecting sentinel nodes in patients with bladder cancer and whether the histopathological status of identified sentinel nodes reflected that of the lymphatic field. MATERIALS AND METHODS A total of 13 patients with bladder cancer who met the criteria qualifying them for radical cystectomy had intravesical injections of radioactive tracer and blue dye marker around the tumor followed by lymphoscintigraphy to visualize lymphatic drainage and detect sentinel nodes. Sentinel nodes were identified preoperatively by the blue color and increased radioactivity and were compared histopathologically with other routinely excised lymph nodes. RESULTS Sentinel nodes were detected in 85% (11 of 13) of patients. There were 4 patients who had sentinel nodes containing tumor cells, and each metastasis was only seen in the detected sentinel node. There were no false-negative sentinel nodes. Of the metastatic sentinel nodes 3 were located outside the normally excised lymph nodes of the obturator fossa. CONCLUSIONS Sentinel nodes can be detected in patients with bladder cancer. The histopathological status of the identified sentinel nodes was diagnostic for all other excised lymph nodes. Sentinel nodes often seem to be located outside the obturator lymphatic field, which is normally examined during preoperative staging of bladder cancer.

Abstract
OBJECTIVE To review published reports on arterio-ureteral fistula. METHOD Literature search. RESULTS Eighty cases were identified. Primary fistulas were mainly seen in combination with aortoiliac aneurysmal disease. Secondary fistulas were seen after pelvic cancer surgery, often with radiation, fibrosis and ureteral stenting or after vascular surgery with synthetic grafting. The dominating symptom is massive haematuria, often with circulatory impairment. The clue to a rapid and correct diagnosis is a high degree of suspicion. Most frequently diagnosis has been obtained through angiography or pyelography. When there is a ureteral stent manipulation it will often provoke bleeding and lead to diagnosis. The fistula must be excluded and a vascular reconstruction made. Most frequently this has been obtained through occlusion of the fistula and an extra-anatomic reconstruction (femoro-femoral crossover). Recently stent-grafting has been successfully used but follow-up is short. CONCLUSION Arterio-ureteral fistula is rare and should be suspected in patients with complicated pelvic surgery and massive haematuria, especially where rigid ureteral stents have been placed.

Abstract
Pycnodysostosis is a rare hereditary bone abnormality with an autosomal recessive mode of inheritance. We report the clinical, radiologic, and endocrine status of 8 children with this rare disease. All patients had the characteristic phenotype of the disorder including short stature (8 of 8), increased bone density (7 of 8), separated cranial sutures (8 of 8), large fontanel with delayed closure (8 of 8), obtuse mandibular angle (8 of 8), delayed teeth eruption (8 of 8), enamel hypoplasia (7 of 8), dysplastic acromial ends of the clavicles (6 of 8), frontal bossing (6 of 8), ocular proptosis (8 of 8), and dysplastic nails (8 of 8). Developmental evaluation according to the revised Denever developmental screening showed normal motor, fine motor-adaptive language, and personal social abilities in all the children. All had normal hepatic and renal functions. Serum calcium and phosphorus concentrations were normal. Two children had low serum alkaline phosphatase concentration. Short stature is a characteristic feature of pycnodysostosis. Seven of the 8 children were born short (length standard deviation score [SDS] = -3 to -1.5). Deceleration of linear growth was significant during the first 3 years of life. All the children had height SDS below -3 at the end of their third year of life. Although short stature is a feature of this genetic disorder, defective growth hormone (GH) secretion in response to provocation with clonidine and glucagon was found in 4 of the 8 patients. These 4 patients had pituitary hypoplasia on the magnetic resonance imaging (MRI) of their brain. In addition, 3 of these 4 patients had demyelination of the cerebrum. Patients with pycnodysostosis (n = 8) had low circulating concentrations of insulin-like growth factor-1 (IGF-1) compared with normal age-matched short children with constitutional short stature (CSS). IGF-I increased significantly after injecting GH for 3 days in these patients. Physiologic replacement with GH (18 U/m(2)/week) divided in daily evening doses subcutaneously increased IGF-1 concentration and improved linear growth velocity and height standard deviation scores (HtSDS) in the 4 children with GH deficiency. These data ruled out GH resistance and proved the usefulness of GH therapy in the management of short stature in these patients. In summary, some patients with pycnodysostosis have partial GH deficiency and low IGF-1 concentration. GH therapy markedly increases IGF-I secretion and improves their linear growth. MRI study of the brain including the hypothalamic-pituitary area is recommended in these children because of the high incidence of pituitary hypoplasia and cerebral demyelination.

Abstract
Colorectal cancers in 92 patients aged 45 years and under presenting over a 20-year period (1970-1990) were studied. A delay of more than 4 months in presentation was seen in 27 per cent of patients. All underwent surgery, 14 per cent emergency and 86 per cent elective, and follow-up was available for 91 patients. Overall, 14 per cent of patients had Dukes A tumours, 32 per cent Dukes B, 36 per cent Dukes C and 18 per cent Dukes 'D'. Local recurrence occurred in eight (9 per cent) of the 92 patients and overall 5- and 10-year survival rates were 61 and 59 per cent. Multivariate analysis identified independent risk factors for local recurrence to be mucinous carcinoma (relative effect 4.9) and the presence of intramural vascular invasion by tumour (relative effect 9.4). For overall survival, independent risk factors were involvement of the regional lymph nodes by tumour (relative effect 2.0), extramural invasion by tumour cells (relative effect 3.0), tumour size (relative effect 1.8) and the presence of metastatic disease at initial diagnosis (relative effect 3.7).

Abstract
This prospective study was undertaken to evaluate the risk of epilepsy after aneurysm operations. The patients were discharged after operation without any anticonvulsant prophylactic treatment and followed-up for 12 months. Out of 128 such patients 121 were submitted for final evaluation. Epilepsy was diagnosed if two or more seizure attacks occurred during that time. Such attacks occurred in 8 patients, so the risk of epilepsy was estimated at 7% for the 12 months after operation in patients without prophylactic treatment. In another 3 patients single seizures occurred during the follow-up, they were not treated with anticonvulsant drugs; seizures did not recur for up to two years. Detailed analysis of the patients with late epilepsy revealed that most of them were pre-operatively in the 3rd clinical group according to WFNS scale. The rationale for the use of prophylactic anticonvulsants after aneurysm surgery seems to be doubtful in view of this study and data from the literature.

Abstract
Behçet's disease is a chronic, recurrent disease that most commonly presents as oral and genital ulcers and iritis. It is a multisystem disease with possible cardiovascular, pulmonary, neurologic, cutaneous and articular involvement. It is most often diagnosed in the 20 to 40 year age group, and vascular and neurologic involvement worsens the prognosis. Vascular manifestations include venous and arterial occlusions, arterial aneurysm and pseudoaneurysm formation. We present the case of a young man with Behçet's disease with multiple aneurysms, pseudoaneurysms, arterial occlusions and venous thrombosis with a literature review. Surgeons must consider Behçet's disease when dealing with aneurysms in young patients.

Abstract
Contrary to an old belief, bile duct carcinoma is not a rare disorder in Egypt. Among 730 patients referred for an ERCP examination, twenty-nine consecutive patients were diagnosed as having bile duct carcinoma. The cause of this type of carcinoma remains unknown. In the present study, only seven of the 29 (24.1%) with bile duct carcinoma patients had associated gallstones. In order to investigate the possible association between typhoid carrier state and bile duct carcinoma, stool cultures were performed for Salmonella typhi and Salmonella paratyphi A and B. Nine out of 23 patients (39.1%) with bile duct carcinoma, 17 out of 50 (34%) with calcular obstructive jaundice, and 1 out of 50 (2%) healthy individuals proved to be salmonella carriers. Statistical analysis of the results confirmed the presence of a significant association between chronic fecal thyphoid carrier state and bile duct carcinoma, while that between calcular obstructive jaundice and bile duct carcinoma was not significant. In conclusion, there might be an association between chronic fecal typhoid carrier state and bile duct carcinoma.
