The major sources of fluorine in the stratosphere are CFC-11 and CFC-12. During the decomposition process, fluorine is first present in the form of carbonyl compounds (e.g. carbonyl fluoride (COF2)). Given its long life time, COF2 is the second most abundant stratospheric fluorine reservoir. Earliest, COF2 vertical distributions were derived from occultation measurements performed by the ATMOS instrument during the SPACELAB-3 Space Shuttle mission in 1985. The Canadian FTIR spectrometer ACE-FTS, onboard the SCISAT-1 satellite, is the first instrument since the last ATMOS flight in 1994, to record COF2 vertical profiles from space. Four years of ACE-FTS occultation measurements are presently available. Several COF2 IR absorption lines located either in the so-called InSb (1-5 µm) and MCT (2-16 µm) spectral ranges can be used to determine its total column from ground-based high-resolution FTIR observations. In addition, we have proposed, during the EGU General Assembly 2007, an original retrieval procedure that allows us to derive information on the COF2 vertical distribution, between 17 and 30 km, from ground-based FTIR spectra recorded at Jungfraujoch. This “multi-microwindows multi-spectra” approach, using the SFIT-2 v3.91 algorithm, has been completely characterized in terms of fitting strategy and information content. Some examples of COF2 vertical profiles inversions were also presented. This year, we will complete the characterization of the multi-microwindows multi-spectra fitting procedure by exposing the full error budget affecting our COF2 partial and total columns products. Also, comparisons with COF2 model runs generated by the 3D CTM KASIMA (KArlsruhe SImulation model of the Middle Atmosphere) will be presented and critically discussed. [less ▲]

Recent studies have suggested the involvement of a unique population of cells at the cervical squamo-columnar junction (SCJ) in the pathogenesis of early (squamous intraepithelial lesion or SIL) and advanced (squamous cell and adeno-carcinomas) cervical neoplasia. However, there is little evidence to date showing that SCJ cells harbour carcinogenic HPV or are instrumental in the initial phases of neoplasia. This study was designed to 1) determine if normal-appearing SCJ cells contained evidence of carcinogenic HPV infection and 2) trace their transition to early SIL. Sections of cervix from high-risk reproductive age women were selected and SCJ cells were analyzed by using several techniques which increasingly implicated HPV infection: HPV DNA (genotyping and in situ hybridization)/RNA (PCR), immunostaining for HPV16 E2 (an early marker of HPV infection), p16ink4, Ki67 and HPV L1 protein. In 22 cases with a history of SIL and no evidence of preneoplastic lesion in the excision specimen, HPV DNA was isolated from 8 of 10 with visible SCJ cells, 6 of which were HPV16/18 DNA positive. In 5 of these latter cases, the SCJ cells were positive for p16ink4 and/or HPV E2. Transcriptionally active HPV infection (E6/E7 mRNAs) was also detected in micro-dissected SCJ cells. Early squamous atypia associated with the SCJ cells demonstrated in addition diffuse p16ink4 immunoreactivity, elevated proliferative index and rare L1 antigen positivity. We present for the first time direct evidence that normal-appearing SCJ cells can be infected by carcinogenic HPV. They initially express HPV E2 and their progression to SIL is heralded by an expanding metaplastic progeny with increased proliferation and p16ink4 expression. Whether certain SCJs are more vulnerable than others to carcinogenic HPV genotypes and what variables determine transition to high grade SIL remain unresolved, but the common event appears to be a vulnerable cell at the SCJ.

AIM: To report the experience of the CHU Sart Tilman, University of Liege, Belgium, in the management of appendiceal carinoid tumor. METHODS: A retrospective review of 1237 appendectomies performed in one single centre from January 2000 to May 2004, was undertaken. Analysis of demographic data, clinical presentation, histopathology, operative reports and outcome was presented. RESULTS: Among the 1237 appendectomies, 5 appendiceal carcinoid tumors were identified (0.4%) in 4 male and 1 female patients, with a mean age of 29.2 years (range: 6-82 years). Acute appendicitis was the clinical presentation for all patients. Four patients underwent open appendectomy and one a laparoscopic procedure. One patient was reoperated to complete the excision of mesoappendix. All tumors were located at the tip of the appendix with a mean diameter of 0.6 cm (range: 0.3-1.0 cm). No adjuvant therapy was performed. All patients were alive and disease-free during a mean follow-up of 33 mo. CONCLUSION: Appendiceal carcinoid tumor most often presents as appendicitis. In most cases, it is found incidentally during appendectomies and its diagnosis is rarely suspected before histological examination. Appendiceal carcinoid tumor can be managed by simple appendectomy and resection of the mesoappendix, if its size is <= 1 cm. (C) 2006 The WJG Press. All rights reserved. [less ▲]

Important progress has been made in the treatment of liver metastases of advanced colorectal cancer. Surgery with curative intent, when possible, shows evidence of prolonged survival. Response rate and overall survival can be improved with modern polychemotherapy. Cytotoxic drug combinations and sequential treatments sometimes make surgery possible for initially non resectable lesions. Impact of loco-regional treatment such as hepatic arterial infusion chemotherapy must be defined in randomised trials. Radiofrequency ablation is also currently evaluated in clinical trials. In this review the benefit of each treatment is discussed. [less ▲]

La carcinomatose péritonéale est définie comme l'envahissement néoplasique secondaire du péritoine. Cette entité peut amener de nombreuses difficultés, à la fois sur le plan de son diagnostic, de sa mise au point et de la recherche de son origine ainsi que pour son traitement. Le cas clinique que nous relatons illustre les difficultés pouvant être rencontrées par l'équipe soignante face à une carcinomatose péritonéale et décrit l'importance d'une approche multidisciplinaire pour sa prise en charge. Lorsque son origine n'est pas déterminée avant l'instauration du traitement, la carcinomatose péritonéale entre dans le cadre des carcinomes de primitif inconnu (CAPI). Chez une femme, une telle présentation de CAPI en fait une entité particulière, facteur de meilleur pronostic, pour laquelle un traitement plus spécifique doit être instauré en première intention.

Merkel cell carcinoma is a skin malignancy showing an increasing trend of incidence in the white population. Its viral origin due to the MC polyomavirus is likely. The diagnosis relies on the histological and targeted immunopathological examinations. Histoprognostic criteria remain to be defined. An assessment using medical imaging is important to establish. Treatments rely on surgery and radiotherapy. Chemotherapy is mandatory at the metastatic stage. Some biotherapies are potentially active. [less ▲]

Dans le cadre de la prise en charge multidisciplinaire du carcinome intracanalaire du sein (carcinome intra-canalaire in situ = DCIS = Ductal Carcinoma In Situ), on évoque souvent la possibilité de renoncer à la radiothérapie complémentaire après un geste de chirurgie conservatrice. S’il est vrai que la radiothérapie, dans ce contexte, n’apporte pas de bénéfice en survie, il n’en reste pas moins qu’on observe à long terme un effet bénéfique en contrôle local. Il existe un effet significativement marqué sur le taux de rechute de type DCIS et de type invasif dans les différentes études randomisées destinées à éclaircir la problématique du rôle de la radiothérapie. La question est de savoir si on peut distinguer un sous-groupe de patientes pour qui le contrôle local n’est pas modifié par l’adjonction d’une radiothérapie adjuvante. Pour l’instant, nous ne sommes pas à même de définir ce sous-groupe, car les critères de sélection n’ont pas été mis à l’épreuve dans le cadre d’un essai randomisé. Faute de ces données, il nous semble plus adéquat de proposer jusqu’à preuve du contraire, une radiothérapie aux patientes opérées, même si l’intervention est a priori radicale, mais conservatrice, et même si les facteurs pronostiques semblent plutôt favorables. Cependant, la radiothérapie n’est pas indiquée après une mastectomie. [less ▲]

OBJECTIVE: Adults with type 1 diabetes may have abnormal alterations in heart rate variability (HRV) due to cardiac autonomic neuropathy. This prospective study was performed to determine whether HRV can be used to detect subclinical autonomic neuropathy in diabetic children. RESEARCH DESIGN AND METHODS: We examined five time domain and three frequency domain HRV indices determined from 24-h Holter recordings in 73 diabetic children and adolescents aged 3-18 years (mean 12.1 years) with a mean duration of diabetes of 55 months. The measures were compared with normal ranges. Z scores were established for each parameter and were compared with classic risk factors of other diabetic complications. RESULTS: Most HRV indices were significantly depressed in children aged > or = 11 years, and the levels of HRV abnormalities were significantly correlated with long-term metabolic control (mean GHb for 4 years) in that age-group. In younger patients, HRV indices were within the normal range and were not correlated with the level of metabolic control. Illness duration and microalbuminuria but not short-term metabolic control (most recent GHb) were also independently predictive of HRV abnormalities. CONCLUSIONS: These results suggest that early puberty is a critical period for the development of diabetic cardiac autonomic dysfunction. Therefore, all type 1 diabetic patients should be screened for this complication by HRV analysis beginning at the first stage of puberty regardless of illness duration, microalbuminuria, and level of metabolic control.
