Abstract Aim:, To evaluate the learning curve of hand-assisted retroperitoneoscopic nephrectomy (HALS) performed by less-experienced surgeons. Methods:, The operative records of 166 patients, including 103 with renal tumors and 63 with renal pelvic or ureteral tumors, who underwent HALS performed by 18 less-experienced urologists were reviewed. Results:, The insufflation time in the first four cases was significantly longer than that in the sixteenth and later cases. The insufflation time in cases 5,10 was 14,24 min longer than that in the cases 16 onward, although the differences were not significant. The estimated blood loss did not differ in each group of cases. The complication rate in early cases, in which the operators' experience was five cases or less, was 6% (4/71), while that in later cases was also 7% (7/95). In the analysis of the learning curve of a single surgeon who performed 57 procedures, the insufflation time in cases 1,5 was significantly longer than in cases 41,57. The insufflation times in cases 5,10 were 45 min longer than those in cases 41,57, although the difference was not significant. The estimated blood loss did not differ in each group of cases. Complications did not seem related to operation experience. Conclusion:, In HALS, 5,10 cases were necessary for less-experienced urologists to gain average operating skills for this procedure. It may be reasonable for less-experienced surgeons to begin standard laparoscopic procedures after experiencing 10 cases of the present procedure. [source]


Laparoscopic pyeloplasty for ureteropelvic junction obstruction: Outcome of initial 12 procedures

Abstract Background:, Open pyeloplasty has been the gold standard for surgical treatment of ureteropelvic junction (UPJ) obstruction, enjoying a long-term success rate exceeding 90%. Unfortunately, this procedure requires a muscle incision that entails some degree of morbidity. We have, therefore, investigated the feasibility of laparoscopic pyeloplasty for UPJ obstruction and report here the outcomes of our early cases. The median follow up is 25 months (range, 12,42 months). Methods:, Between March 1999 and September 2001 we performed laparoscopic pyeloplasty on 12 ureters in 11 patients presenting with symptomatic hydronephrosis, secondary to a short stenosis of the UPJ or to ventrally crossing vessels; bilateral pyeloplasty was performed as a single procedure in one patient. We performed dismembered Anderson,Hynes pyeloplasty, Fenger plasty and Y-V plasty in eight, two and two ureters, respectively. All procedures were carried out transperitoneally. Results:, The procedure was completed successfully in all cases. Crossing vessels were noted in six of 12 ureters (50.0%). Mean operative time and blood loss in 11 patients (including one bilateral case) were 272.8 min (range, 175,480 min) and 96.4 mL (range, 20,340 mL), respectively. Postoperative complications were noted in two patients (18.2%): one instance of prolonged urine leakage and one anastomotic re-stricture. Eleven of 12 ureters (91.6%) demonstrated a patent UPJ on excretory urography and/or improvement of renal function on diuretic renography at a minimum follow up of 12 months. Conclusion:, Although the procedure requires advanced laparoscopic skills, it can be safely and successfully completed as frequently as the conventional open procedure. Laparoscopic pyeloplasty seems to be a valuable alternative to open pyeloplasty for UPJ obstruction. [source]


Psychiatric injury in breach of a relationship

LEGAL STUDIES, Issue 1 2007
Peter Handford
The distinction between primary and secondary victims confirmed by Page v Smith has caused major problems in English psychiatric damage law. The House of Lords has suggested that the search for principle has been called off, and that the only sensible strategy is to say ,thus far and no farther'. This paper suggests that one way forward is to recognise that it is not only persons who are physically proximate to an ,accident' who should be put in a special category: any case in which there is some sort of pre-existing relationship between claimant and defendant should be regarded as different from the standard secondary victim scenario. The relationship concept, first recognised in the USA and now adopted by the Court of Appeal, can be found in embryo form in the early cases. [source]


Changing Perceptions of Non-Consensual Sex Crime: The Mediation of a Local Newspaper

THE HOWARD JOURNAL OF CRIMINAL JUSTICE, Issue 5 2009
KEITH SOOTHILL
Abstract: This article aims to consider all cases of non-consensual sex crime involving a court appearance that were reported in a local newspaper, the Lancaster Guardian, over a period of 120 years (1860,1979). Searching over 6,000 editions of a local newspaper, there are huge shifts in the outcome of non-consensual cases over the 120 years. There is evidence of a lively direct interest from the local populace in some of the early cases, but it is only since the Second World War that more sustained coverage of cases are featured in the newspaper. There is a clear shift over time in the type of cases that receive more media attention. [source]


Multiple sclerosis: Distribution of inflammatory cells in newly forming lesions,

ANNALS OF NEUROLOGY, Issue 6 2009
Andrew P. D. Henderson MBBS
Objective CD4 T-cell,dependent macrophage activation directed against a myelin or oligodendrocyte antigen is generally thought to be the mechanism causing myelin destruction in multiple sclerosis (MS). However, areas within expanding MS lesions may exhibit prominent oligodendrocyte loss and apoptosis in the absence of infiltrating lymphocytes. The present study was designed to further investigate the inflammatory profile of different regions within rapidly expanding MS lesions. Methods Twenty-six active lesions from 11 patients with early MS were serially sectioned and immunostained for T and B cells, plasma cells, ramified microglia, macrophages, monocytes, and CD209-positive dendritic cells. Cell counts were compared in prephagocytic, phagocytic, and immediately postphagocytic areas. Results Parenchymal T and B cells were largely absent in areas of initial oligodendrocyte loss and in areas of degenerate and dead myelin infiltrated by myelin phagocytes. In contrast, trailing areas of complete demyelination packed with lipid macrophages, and, in some lesions, regenerating oligodendrocytes, showed large numbers of T cells, B cells, and immunoglobulin G (IgG)-positive plasma cells. Lesions in 2 exceptionally early cases contained relatively few T and B cells, and no IgG-positive plasma cells. Interpretation Early loss of oligodendrocytes is a prominent feature in tissue bordering rapidly expanding MS lesions. Macrophage activity is largely an innate scavenging response to the presence of degenerate and dead myelin. Adaptive immune activity involving T and B cells is conspicuous chiefly in recently demyelinated tissue, which may show signs of oligodendrocyte regeneration. The findings suggest that plaque formation has some basis other than destructive cell-mediated immunity directed against a myelin or oligodendrocyte antigen. Ann Neurol 2009;66:739,753 [source]


Frequent occurrence of B-cell lymphomas in angioimmunoblastic T-cell lymphoma and proliferation of Epstein,Barr virus-infected cells in early cases

BRITISH JOURNAL OF HAEMATOLOGY, Issue 6 2007
Klaus Willenbrock
Summary Secondary lymphomas occurring in the setting of angioimmunoblastic T-cell lymphoma (AILT) are considered to be rare. Their occurrence has been attributed to Epstein,Barr virus (EBV)-associated lymphoproliferations. A previous study detected a dysregulated hypermutation process in B-cells of AILT. The present study aimed at estimating the frequency of B-cell lymphomas in AILT. By studying the expression of EBV and activation-induced cytidine deaminase (AID) as an indicator of hypermutating cells, we assessed whether B-cell lymphoproliferations in AILT were strictly associated with EBV and whether hypermutation might contribute to lymphomagenesis. Among 161 cases of AILT, diagnosed between 1996 and 2005 at the lymph node registry, Frankfurt, Germany, 19 cases were detected that also had B-cell non-Hodgkin lymphoma (NHL) and two cases had classical Hodgkin lymphoma (HL). EBV was detected in tumour cells of 7/18 NHL and both HL, suggesting that factors other than EBV contribute to lymphomagenesis. AID was expressed in AILT in large cells disseminated in the tissue, implying that the process of somatic hypermutation is ongoing in AILT, although the GC architecture is disrupted. This might be relevant in the development of secondary lymphomas. [source]


Community-based multiple screening model,,§¶

CANCER, Issue 8 2004
387 participants Taiwan community-based integrated screening group, Design, analysis of 4, implementation
Abstract BACKGROUND Multiple disease screening may have several advantages over single disease screening because of the economics of scale, with the high yield of detecting asymptomatic diseases, the identification of multiple diseases or risk factors simultaneously, the enhancement of the attendance rate, and the efficiency of follow-up. METHODS An integrated model of community-based multiple screening was designed and conducted between 1999 and 2001 in Keelung, Taiwan. The authors used a Papanicolaou (Pap) smear screening program as a base to integrate other screening regimens encompassing four other neoplastic diseases and three nonneoplastic chronic diseases. Screening methods, the interscreening interval, and the follow-up for each screening regimen were designed based on evidence-based literature and current national screening policy. RESULTS A total of 42,387 subjects participated in the screening activities. A 25% increase in the attendance rate for Pap smear screening was demonstrated after the introduction of multiple disease screening programs. At the first screen, this program yielded a total of 677 asymptomatic neoplasms (16.0 per 1000), including a large proportion of precancerous lesions and small presymptomatic tumors without lymph node involvement. The association between the occurrence of neoplasm and the presence of comorbid nonneoplastic chronic disease was found to be statistically significant (odds ratio, 1.64; 95% confidence interval, 1.38,1.94 [P < 0.05]). The authors also identified 5314 subjects with metabolic syndrome who were at a greater risk for colorectal and oral neoplasias. CONCLUSIONS The results of the current study demonstrate that an outreach and community-based multiple screening program not only enhances attendance rates but also has a high yield of early cases of various diseases simultaneously, and provides a natural opportunity to elucidate the correlation between neoplastic disease and nonneoplastic chronic disease.
