Support the use of beta-blockers, CCBs, and nitrates after CABG. The results of this review point to an urgent need for additional studies investigating cardiac medical therapy in the post-CABG patient.
In our ICU we have experience with more than 150 retrograde jugular cannulations performed by senior intensivists and we reported six carotid artery punctures and one erroneous positioning in the subarachnoid space. We are surprised that authors with much more experience than ours do not report major complications other than carotid artery puncture. In fact many cases of complications after jugular catheterization have been reported. Zullo, Wallerson and Lang [1] for example described the formation of a fistula between the common carotid artery and internal jugular vein. Robinson, Jewkes and Kendall [2] noted a vertebrovertebral arteriovenous fistula as a complication of internal jugular catheterization. In difficult cases these and other authors [35] suggest the use of two-dimensional imaging echography coupled to colour Doppler examination to guide central venous cannulation. McGee and Mallory [6] included spinal cord cannulation and neck haematomas causing severe compression and obliteration of the trachea. In conclusion, we believe that the possibility of rare but dramatic complications exists and we should be able to prevent and recognize these rare complications. We suggest radiographic examination and, when it is useful for doubtful catheter positioning, even contrast media. P. FUMAGALLI F. LUSENTI C. MARTINI R.

Tarceva and gemzar for pancreatic cancer
Excess1973, i would say alot of your mom's good responce is due to the avastin as like tarceva when it works it is an amazing drug.
By DEAN OLSEN STAFF WRITER A new drug that interferes with cell reproduction will be tested to find out if it improves an already innovative technique for treating head and neck cancer, doctors at Southern Illinois University School of Medicine said Wednesday. In a first-of-its-kind treatment that will be offered only in Springfield, 20 patients with advanced-stage tumors will receive the drug Tarceva in addition to a treatment that targets tumors with chemotherapy, according to SIU doctors at the school's Sim- monsCooper Cancer Institute. Doctors believe Tarceva, already proven to enhance chemotherapy for lung- and pancreatic-cancer patients, will help prevent recurrence of tumors of the mouth, tongue and throat, as well. "We're targeting our therapy with 'smart weapons' here, " said Dr. Krishna Rao, an SIU oncologist who is conducting the study with institute director Dr. K. Thomas Robbins. "This is a war on cancer, " Rao said. "We've called in the Army and the Navy, and now we're bringing in the Air Force." The National Cancer Institute estimates that 39, 000 Americans develop head and neck cancers each year, accounting for about 3 percent to 5 percent of all cancers in the United States. The cancers often are associated with smoking and excess alcohol consumption. The clinical trial at SIU has received approval from the U.S. Food and Drug Administration and will be funded with a , 000 to , 000 grant from California-based Genentech Inc., maker of Tarceva. If the yearlong trial shows positive results, it could be expanded to other cities, said Rao, 38, a native of India who came to SIU in 2002 from the Fred Hutchinson Cancer Research Center in Seattle. "We feel we're on the cutting edge with this, but it's also building on what we've been able to achieve thus far, " he said. For seven weeks, patients will receive a type of chemotherapy pioneered in the 1990s by Robbins, a head and neck cancer surgeon, when he was on the faculty of the University of Tennessee. Robbins, 57, a native of Newfoundland, Canada, brought the treatment to Springfield when he joined SIU in 2003. Through a catheter in the neck, patients receive the chemotherapy drug cisplatin in an artery that feeds the tumor - so the cancer receives a concentrated dose. To help reduce side effects of the chemotherapy elsewhere in the body, the patient receives intravenous doses of a chemical compound and tarka.
As being either primary or secondary in origin. The primary forms tend to be idiopathic, unassociated with other diseases, and are either acute or chronic in nature. Conversely, the secondary forms are seen in conjunction with another disease process such as diabetes and amyloidosis ; or alternatively occur owing to a known biochemical or structural deficiency or after exposure to known toxic agents such as alcohol and heavy metals ; . A brief description of each subtype follows, along with references for the reader who desires a more in-depth discussion.

The researchers concluded that patients with nsclc who demonstrate disease control with iressa and do not have egfr mutations appear to have benefit from treatment with tarceva once their cancer progresses following treatment with iressa and taxol.
It cannot explain the origin of matter. Answer: Matter is eternal. It cannot explain the complexity of matter. Answer: Billions of years of evolution are responsible for the complexity of matter. It cannot explain the emergence of life. Answer: Primordial life evolved from biopolymers that evolved from inorganic compounds. It cannot explain the appearance of God-consciousness in man. Answer: This too was the product of evolution.

Estimation of half-maximal inhibition of HERG channels None of the compounds induced significant resting state block. The amount of inhibition during 3 min preincubation was either absent or very small o10% ; . Use-dependent HERG channel block was estimated as peak tail current inhibition. The tail currents were measured at 40 mV, after a step to 20 mV. The concentrationinhibition curves were fitted using the Hill equation IHERG; drug IHERG; control 100 A 1 C IC50 nH A; where IC50 is the concentration at which HERG inhibition is half-maximal, C is the applied drug concentration, A is the fraction of HERG current that is not blocked and nH is the Hill coefficient and tazorac.
Recent accomplishments have been collaborative studies with our partners especially in Canada and Scandinavia looking at therapeutic options in first-line ovarian cancer. The TEC versus TC 55985 ; trial has now been reported as showing no survival advantage with the triple-drug regime. The recently closed 55012 trial, looking at sequential doublets in first-line ovarian cancer, is currently undergoing analysis. Meanwhile, the Gynaecological Cancer Group has just opened a very exciting study investigating erlotinib Tarceva ; as maintenance therapy after first-line treatment with carboplatin and paclitaxel in ovarian cancer 55041 ; . This clinical trial has a major TR component. However, probably the most important clinical trial the group is conducting at present 55971 ; compares neo-adjuvant chemotherapy prior to surgery to the gold standard of primary debulking surgery followed by chemotherapy. This study is close to its recruitment target of 700 patients and should thus close this year. The results of the 55971 trial will have a massive impact on clinical practice. In second-line studies on ovarian cancer we have recently collaborated with the German group AGO looking at carboplatin and gemcitabine versus carboplatin alone 55001 ; , showing a superiority in progression-free survival for this combined drug regime. The group is about to open the 55051 CALYPSO study in platinum sensitive disease in which we will be working as joint partners of the French group GINECO. In this study, carboplatin and liposomal doxorubicin will be compared to carboplatin and paclitaxel. For relapsed disease we have built on the pioneering work of Maria van der Burg looking at dose-dense weekly carboplatin paclitaxel which in phase-2 studies has shown outstanding potential and activity in Platinum resistant disease where historically poor response rates have been observed. Linked into all these studies is a strong component of translational research. We are increasingly recognising the importance of quality assurance and quality control.We also hope that some of our more active members will be collaborating within the new drug development programme which has several projects that may incorporate ovarian cancer. In cervix cancer, the Gynaecological Cancer Group is also involved in a study of enormous international potential the 55994 study which compares neo-adjuvant chemotherapy prior to surgery against concomitant chemoradiation. This study is coming up towards the half-way mark and because of the declining incidence of cervix cancer in Western Europe we are looking for other partners to help support and maintain this study in terms of accrual. Future directions include newer agents such as anti-angiogenesis drugs and we are working with other groups in phase-1 and phase-2 studies while we gear towards a new phase-3. New-imaging studies are also important as they may help to define optimal treatment strategies and these include PET CT as well as dynamic MRI studies which are helping to define new drug developments . For endometrial cancers, the TAP versus AP study 55984 ; has recruited poorly, like all other international endometrial cancer studies, and it will probably close this year. Future directions involve looking at newer molecular targeted agents including the mTOR pathway inhibitors. The increasing global incidence of endometrial cancer will make this more important as the years go by and uterine cancer becomes more prevalent than ovarian cancer in Western countries.
Tarceva prognosis lung cancer
Effects in the lung, supporting our observations. The aromatase enzyme catalyzes the conversion of androgens to estrogens and is expressed in the lung 37, 38 ; . No preclinical work has been done using aromatase inhibitors for lung cancer therapy; however, a recent report suggests that this approach may be worth pursuing 39 ; . In this respect, Coombes et al. reported a decreased incidence of primary lung cancer in breast cancer patients treated with exemestane after 2 to 3 years of tamoxifen therapy 4 cases ; compared with continued tamoxifen treatment 12 cases ; . Because lung tumors from both male and female patients express ERs and cell lines derived from both sexes respond to estrogens and anti-estrogens, these types of therapeutic treatments could be useful for both populations, not just women 3 ; . There are also several strategies that have been developed to target EGFR and block its activation in cancer cells. Inhibitors of this pathway include monoclonal antibodies, such as C225 cetuximab or Erbitux ; , directed against the extracellular domain of EGFR, which compete with ligand for receptor binding and prevent kinase activation. C225 is currently in phase II and III trials for the treatment of NSCLC 40 ; . Additional antibodies are in clinical development for NSCLC, including the fully humanized monoclonal antibody ABX-EGF 41 ; . The other anti-EGFR agents are the EGFR tyrosine kinase inhibitors, such as gefitinib and erlotinib OSI-774 or Tarceva ; , which prevent autophosphorylation of EGFR by physical interaction with its intracellular kinase domain 42 ; . Gefitinib is currently available for treatment of advanced NSCLC and erlotinib is in phase III clinical development. Several other EGFR-targeted compounds are in preclinical or early clinical trials for NSCLC treatment 4345 ; . Together, these data on clinical drug development of both the ER and EGFR pathways support our choice of fulvestrant and gefitinib for lung cancer treatment. One area of cross-talk that has critical importance in cancers is the interaction between ERs and growth factors. Polypeptide growth factors, such as EGF and insulin-like growth factor-I, stimulate the transcriptional activity of ERs in an estrogenindependent manner. There is evidence that EGF can directly phosphorylate nuclear ERa at Ser118 or ERh at Ser124 by phosphop44 p42 MAPK 46 ; . Recent studies suggest that there is also a nonnuclear ER that can activate phosphatidylinositol 3V -kinase and the EGFR family of receptors 6 ; . This suggests that in cells that express both EGFR and ER estrogen may stimulate cell proliferation and survival through these alternate pathways and that bidirectional signaling between these two receptors is a potent method of augmenting both estrogen and growth factor action. The rapid responses that we observed in phospho-EGFR and phospho-p44 p42 MAPK suggest that the nonnuclear ER transactivation of EGFR exists in lung cancer cells. Targeting EGFR in combination with traditional hormone therapy could be of benefit by increasing tumor cell death and preventing signaling through this alternate growth pathway. Targeting both of these pathways is not without precedence and combining therapies to target several aspects of signal transduction should have the most beneficial antitumor effects. Recently, the combination of gefitinib and fulvestrant has been tested in breast cancer cells and an additive effect was observed 25 ; . The addition of an EGFR inhibitor in combination with antihormone therapy in breast cancer patients has been proposed to combat hormone resistance. Breast cancers have also been shown to synthesize estrogens and estrogen is produced locally in tumors from postmenopausal women through the action of aromatase and telithromycin.

Phenotype among different populations e.g., approximately 20% of Chinese and 3% of Caucasians are homozygous for deficient CYP2C19 alleles and lack enzyme activity ; Daniel and Edeki, 1996 ; . Variable clinical responses to flunitrazepam have been reported Boxenbaum et al., 1978; Wickstrom et al., 1980 ; . If flunitrazepam, like diazepam, is metabolized by CYP2C19, the polymorphic expression of this enzyme may affect the clinical safety and efficacy of this drug. Poor metabolizers lacking enzyme activity might experience the sedative and amnesic effects of flunitrazepam at lower doses and for longer periods of time than those who metabolize the drug more efficiently extensive metabolizers ; . The present study investigated, in vitro and in vivo, the role of CYP2C19 and CYP3A4 in the metabolism of flunitrazepam and formation of its major metabolites desmethylflunitrazepam and 3-hydroxyflunitrazepam and tarceva.

ERLOTINIB TARCEVA ; EXPERIENCE IN A PUBLIC HEALTH SYSTEM, MINORITY PATIENT POPULATION WITH PROGRESSIVE METASTATIC NON-SMALL CELL LUNG CANCER MNSCLC ; Sunita Nathan MD * Pritesh Patel MD Jennifer Sharma MD Joyce Samuel MD John H. Stroger Jr. Hospital of Cook County, Chicago, IL PURPOSE: Erlotinib is a tyrosine kinase inhibitor used as second and third-line therapy in patients with metastatic NSCLC mNSCLC ; . We report our experience with erlotinib use in a minority patient population. METHODS: Data from 33 patients with mNSCLC treated at Cook County Hospital, Chicago, Illinois over a 2 year period were collected. Demographics, pathology of primary disease, indication for erlotinib, tolerability and response were analyzed. RESULTS: 33 patients average age 60.1 yrs, range 31-73 yrs ; were identified and analyzed as a retrospective cohort. 54.5% were African American AA ; , 3% Caucasian, 18.2% Hispanic, 21.2% Eastern European, and 3% Asian. 78.8% of patients were smokers. 21.2% were non-smokers, who were all non-AA. 87.9% of pts had failed a previous platinum-based regimen. Erlotinib was used as first line treatment in 12.1%, due to refusal of chemotherapy or poor performance status. 21 63.6% ; pts had erlotinib-related toxicities including skin rash, diarrhea and nausea. Erlotinib dose was reduced in 3 pts and discontinued in 3 pts due to toxicities. AA pts were significantly older than non-AA pts 63.4 vs 51.4 p 0.04 ; . Average duration of response DOR ; was 3.5 months m Range 2 weeks wks ; to 20m [AA 2.36m; Range 2wks to 7m, non-AA 4.87m; Range 2wks to 20m]. Non-AA pts trended towards a longer DOR than AA pts 4.87m vs 2.36m, p 0.08 ; . DOR was comparable in AA male and AA female pts 2.29m vs 2.55m ; and slightly improved in non-AA females than non-AA males 5.3m vs 4m ; . CONCLUSION: In this primarily minority-based cohort AA pts were generally older with a shorter DOR than the non-AA pts. This could be due to the non-AA cohort having a higher percent of non-smokers and probably more responsive to biologic agents. Overall erlotinib was well tolerated. Since the number of patients is small, definitive conclusions in either cohort cannot be made. Further investigation in minority patients is warranted.

Chemoprophylaxis group 66.0% versus 14.8% ; . It was impossible to distinguish early and late primary attacks during and after the malaria risk period in the second year. However, among the cases presenting before the second round of chemoprophylaxis, late primary attacks were more prevalent in the group receivt t ing chemoprophylaxis, suggesting that the proportional difference between the chet t moprophylaxis and notchemoprophylaxis groups in late primary attacks occurring after the start of the second round can be considered to be a conservative estimate, and thus it appears that our results are not greatly affected by misclassification bias. The second limitation is that the number of late primary attacks might have been overtestimated because gamet t tocytetbearing subjects can reintroduce malaria to mosquitoes outside the risk area. However, the number of secondary t and tertiary transmitted cases was probt ably small and is unlikely to have affected our results, because no cases among soldiers and few civilian cases 23 out of 609 cases in 2003 ; were reported in nontrisk areas during the study period, and most of those cases had a history of travel to malaria risk areas.5 and targretin
