Cervical cancer is rare, " she continues, "especially if you have a history of normal Pap tests. And even if you have an early, small cancer less than one centimeter ; , there's nearly a 100 percent chance of being disease-free for at least five years." The ACS recommends annual Pap tests and pelvic exams beginning within three years after a woman first has vaginal intercourse and no later than age 21. After age 30, with three normal, consecutive test results, screening can stretch to every two to three years. Ask your doctor what's best for you. Each year, sexually transmitted diseases STDs ; affect more than 13 million Americans two-thirds of them younger than 25 ; , reports the National Institute of Allergy and Infectious Diseases. Often, STDs show no symptoms, particularly in women, though the infection can still be transmitted to other sex partners. The most common STDs include the following: Chlamydia--Because most people do not have symptoms, chlamydia may not be noticed until it causes severe problems. Left untreated, this STD can cause women and men to become sterile. G onor rhea--Sy mptoms a re of ten m i ld nonexistent ; and are easily mistaken for a bladder or vaginal infection. Antibiotics can cure this STD. HPV human papillomavirus ; --Symptom-free and incurable, HPV can cause abnormal Pap tests and possibly lead to cervical cancer. Early detection is the key to preventing complications from HPV see page 11 ; . Genital herpes--This condition is detectable only when lesions are present. Medication can help relieve the painful blisters that come and go. Syphilis--This disease begins with a painless sore that, if left untreated, can cause illness in the long term. If detected early, it can be easily treated. Trichomoniasis--This curable STD may bring about a yellow-green vaginal discharge with a strong odor, and discomfort during urination and intercourse. continued on page 10.

Dexamethasone for men
Between postnatal risk factors and study outcomes; these limitations also must be considered when interpreting our results. The validity of the PVL and IVH definitions that were used in this study also can be debated given concerns of the incompleteness of the current IVH staging method, crude conceptualization of PVL, and exclusion of ventricular enlargement and cerebellar or brainstem lesions, as done in this study, to reflect accurately the spectrum of neonatal white matter damage that neuropathologically correlates to neurodevelopmental morbidity.34 Furthermore, the reliability of neonatal cranial ultrasounds for routine detection of neuropathologic entities may be lower than believed by neonatal practitioners.35, 36 For these reasons, we are planning a neurodevelopmental follow-up of this cohort when they reach 18 to 22 months' corrected age to assess further the possible differential long-term neurodevelopmental effects of dexamethason4 and betamethasone not reflected by neonatal cranial ultrasound imaging. Conclusion The current study provides evidence that betamethasone statistically reduces the risk for neonatal death, whereas dexamethaxone does not, in agreement with the findings by Crowley.7 Furthermore, there were notable trends for a reduced risk for adverse neonatal outcomes associated with betamethasone compared with dexamethasone for IVH and severe ROP. However, there were no alterations in risk for PVL associated with either antenatal steroid compared with each other or with the absence of antenatal steroid exposure. On the basis of these findings and those of other authors, a randomized, clinical trial on the differing fetal and neonatal effects of dexamethasone and betamethasone should be considered. Given that no such clinical trial yet has been performed, the findings of the current study have implications regarding the selection of antenatal steroid for standard prophylactic purposes. Given the current body of literature favoring the use of betamethasone versus dexamethasone, it may be in the best interest of neonates to receive antenatal betamethasone rather than antenatal dexamethasone when the option is available to do so.

More is being discovered about this condition. There are controversies as to the role of allergy and diet manipulation, and how many people are actually helped by diet. Furthermore, sometimes symptoms may improve with diet manipulation, but the underlying inflammation may still persist. At this time it is not clear how aggressive treatment should be in all cases; should we aim to settle the symptoms, or try to control the underlying inflammation as well? More patients are being reported with symptoms during the pollen season, suggesting that inhaled allergen or perhaps swallowed pollen ; may cause problems in some people.

2.85 billion This $30 billion a year is one of the easiest and largest sources of savings available to the Federal Government. By negotiating for all drugs, Congress could save enough money to not only fund current SCHIP obligations but would have enough savings to expand it to cover nearly all uninsured American Children. Although ultimately a political decision, it is also worth examining who could benefit from these savings. Of the $692 million in potential savings for Missouri, approximately $231 million a year would go to Missouri seniors who would pay less under their Part D plans. As the very raison d'etre of Part D is to help these struggling seniors access.

May be localized primarily to mitochondria in heart and other organs11 and that Kir 6.2 is localized to the sarcolemma, it appears that these 2 channels are differentially regulated under acute and chronic conditions. It is interesting to speculate that these 2 channels may also play different roles in the response to acute or chronic ischemia. In this regard, evidence is rapidly accumulating that the KATP channel may be the end effector molecule responsible for the cardioprotective effects of both the early and delayed phases of ischemic preconditioning15; therefore, future studies like the present one by Jovanovic et al4 using recombinant KATP subunits should allow us to better understand the role and function of KATP channel subtypes in producing cardioprotection and lead to the development of site-specific pharmacological agents that may have potential therapeutic uses.
INTRODUCTION Multiple myeloma MM ; is a plasma cell cancer characterised by paraproteins in the serum or urine and a bone marrow plasmacytosis of over 10%. Common symptoms include bone pain, recurrent or persistent infection, anaemia, renal impairment or a combination of these [1]. There is currently no cure for MM. The 5-year survival rate has been estimated as 19%, however precise figures are difficult to obtain [2, 3]. Treatment for myeloma has changed beyond recognition in the past decade. Initial or induction chemotherapy is indicated for the management of symptomatic MM and to slow progression of the disease. Current treatments include melphalan or cyclophosphamide both with or without prednisolone ; , combination regimens including these alkylating agents, VAD vincristine and doxorubicin with high dose dexamethasone ; and related regimens, or high dose dexamethasone alone [1]. High dose therapy HDT ; comprising of high dose melphalan or total body irradiation with autologous stem cell transplantation is increasingly being used [1, 2]. Time to disease progression may be prolonged with interferon maintenance therapy [2]. Bone pain is treated with analgesics, radiation and bisphosphonates [1]. Almost all patients will eventually relapse with an expected survival time of 6 to months [1, 4]. Treatment options for relapsed disease include repeating the initial chemotherapy, use of high dose dexamethasone HDD ; alone, use of thalidomide, or double hemibody irradiation [1]. DRUG ACTION Bortezomib, a modified dipeptidyl boronic acid, is a selective, reversible inhibitor of the 26S proteasome, a multi-enzyme complex present in mammalian cells. These proteasomes catalyse the breakdown of proteins involved in cell division. Inhibition of proteasome activity disrupts the cell cycle, leading to cell death. Cancer cells are more sensitive to the action of bortezomib than normal cells [5, 6]. Bortezomib has a mean elimination halflife of 9 to hours at doses ranging from 1.45 to 2.00 mg m2 in patients with advanced malignancies. The pharmacoki2 netics of bortezomib have not been fully characterised at the dose recommended for the treatment of multiple myeloma. It is metabolised primarily by the cytochrome P450 enzymes, including 3A4 and 2D6. The effects of age, gender, and race on the pharmacokinetics of bortezomib have not been evaluated. No pharmacokinetic studies have been conducted in patients with renal or hepatic impairment [6]. PROPOSED INDICATION Millenium Bortezomib Velcade, Pharmaceuticals Inc Ortho Biotech ; was granted a CPMP Positive Opinion, under exceptional circumstances, in January 2004 for the treatment of patients with multiple myeloma who have received at least two prior therapies, and have demonstrated disease progression whilst taking the last therapy. Treatment should be administered under the supervision of a physician qualified and experienced in the use of chemotherapeutic agents. PROPOSED COST COURSE Bortezomib is given intravenously in a cycle of 1.3 mg m2 twice weekly for 2 weeks followed by a 10-day drug-free interval [6]. In the main phase II trial the mean number of cycles administered was six [6]. The Summary of Product Characteristics will limit the number of cycles administered to a patient to a maximum of eight [Personal communication, Ortho Biotech, January 2004]. Although the final UK price is to be determined, the cost per cycle of treatment is expected to be in the region of 2, 800 to 3, 200 [Personal communication, Ortho Biotech, March 2004]. EFFICACY Bortezomib, either alone or in combination with dexamethasone, for the treatment of relapsed, refractory MM has been evaluated in two open-label phase II trials and results from a phase III study are awaited. Efficacy has been assessed in terms of clinical response. Phase II trials The SUMMIT trial This was an open label, multicentre study including 202 patients with relapsed.

Soluble tTg Immunostaining. Detection of soluble tTg on formalin-fixed, paraffin-embedded sections showed little detectable staining in the normal kidney Figure 1, A ; . Any immunostaining was predominantly in the glomerulus in a pattern that would be consistent with a mesangial distribution. Occasionally, some very faint staining was seen in the extracellular areas. In biopsy samples, increased immunostainable tTg was detected in both glomerular and tubular compartments Figure 1, B through D ; . Glomerular staining appeared to be generally mesangial in nature Figure 1, C ; and was associated with areas of hypercellularity, with significant correlation between the two R2 0.73, P 0.001 ; .
