The trimethoprim-sulphamethoxazole TMP-SMX ; combination antibiotic is an extremely common medication given for treatment of a variety of infections. The most common side-eects of this drug are neutropenia and the dermal and systemic hypersensitivity reactions associated with sulphonamides [1]. TMPSMX has also been associated with two major forms of nephrotoxicity, acute interstitial nephritis [2] and a decrease in creatinine clearance with mild elevation in serum creatinine [3]. In recent years, the adverse eect of hyperkalaemia has been reported in AIDS patients 710 days after the start of high doses of TMP-SMX therapy for treatment of Pneumocystis carinii pneumonia [4, 5] and in hospitalized patients treated with standard doses of TMP-SMX [6 ]. The mechanism for the hyperkalaemia was established as blockade of sodium channels by TMP-SMX, leading to reduced renal potassium excretion. The sodium-channel blocking eect of TMP-SMX is similar to that of amiloride [47 ]. Voltage-dependent distal renal tubular acidosis RTA ; induced by standard doses of TMP-SMX has not been previously reported. Herein we present a case of this form of distal RTA with hyperkalaemia in a patient receiving standard doses of TMP-SMX for prolonged treatment of a urinary tract infection.
Characteristics ASICs are membrane protein complexes formed by four subunits among the six characterized isoforms Fig. 1 ; . The isoforms are coded by four different genes, two of them spliced in two variants: ASIC1a and ASIC1b, ASIC2a and ASIC2b, ASIC3 and ASIC4 Chen et al. 1998; Garcia-Anoveros et al. 1997; Grunder et al. 2000; Lingueglia et al. 1997; Waldmann et al. 1997a; Waldmann et al. 1997b ; . Each subunit is 510 to 560 amino-acids long, with two transmembrane domains and a large extracellular loop, and belongs to the ENaC DEG ASIC family Fig. 2 ; Waldmann and Lazdunski 1998 ; . The properties of the channels i.e. activation and inactivation kinetics, pH sensitivity, ion selectivity ; vary according to their subunit composition. For example, ASIC1a opens transiently for pH values from 7.2 and under with a pH50 of 6.2, and is sodium selective Waldmann et al. 1997b ; Fig. 3 ; . ASIC3 generates a biphasic current: the transient current is followed by a sustained current that lasts as long as the pH is low Waldmann et al. 1997a ; Fig. 3 ; . It has been associated with cardiac ischemic pain Sutherland et al. 2001 ; , and ASIC3-deficient mice display alterations in the modulation of high-intensity pain stimuli Chen et al. 2002 ; . Some isoforms have no activity when expressed alone: the isoform ASIC2b modifies the properties of the other subunits when present in heteromeric complexes Lingueglia et al. 1997 the isoform ASIC4 has absolutely no activity, either alone or with other isoforms Grunder et al. 2000 ; . The association of ASIC3 and ASIC2b forms a channel with an ion selectivity and a pH sensitivity that is similar to those of an endogenous native current widely expressed on sensory neurons Benson et al. 2002; Lingueglia et al. 1997 ; , and that can participate in the sustained neuronal activity observed in lasting acidic pain states such as inflammatory and ischemic pain. ASIC isoforms can be localized exclusively in sensory neurons and particularly nociceptors ASIC1b and ASIC3 ; , or in both sensory and central neurons ASIC1a, ASIC2a and 2b ; . Their role as pH-sensors on sensory neurons occurs particularly in pathophysiological situations when tissue pH decreases. During inflammation, ischemia, around a fracture or a tumor, the extracellular pH can be lower than 6. This acidosis is directly responsible for pain feelings, and bicarbonate solutions used to be infused in arthritic joints to diminish pain. ASIC currents are sensitive to amiloride but with relatively low affinities around 10 M ; . ASIC1a is also potently inhibited by a peptidic toxin isolated from tarantula venom Escoubas et al. 2000 ; . It has been shown that NSAIDs directly block recombinant and native ASIC currents Voilley et al. 2001 ; . Ibuprofen and flurbiprofen inhibit ASIC1a-containing channels, and aspirin, salicylate and diclofenac inhibit ASIC3-containing chan.
Evaluation of haplotype sharing on 12p13 As outlined above, a transmission disequilibrium at TNFRSF1A markers was observed among all CF families and the same TNFRSF1A intragenic background was enriched among our concordant mildly affected siblings. We have evaluated the 12p13 haplotypes of our CF patients to describe the chromosomal segment that is shared among all CF sibs carrying the allele 10 ; at D12S889. Results of the haplotype reconstruction for D12S889 and the SNPs typed in CD9, FLJ10665, TNFRSF1A and SCNN1A are displayed in Tables 3a and 3b. At rs740842-D12S889 codon 35 of FLJ10665 to intron 1 of TNFRSF1A ; , most chromosomes carry T 10 ; but the rare haplotype C 10 ; is observed in four families indicating an ancestral recombination breakpoint between rs740842 and D12S889. For D12S889-rs2228576 intron 1 of TNFRSF1A to codon 663 of SCNN1A ; , most chromosomes carry the haplotype 10 ; G while the recombined haplotype 10 ; A was seen in two families. Hence, direct reconstruction of haplotypes allowed us to The amiloride-sensitive sodium channel ENaC is known for its role in body electrolyte and water regulation Rossier et al. 2002 ; . Mutations within ENaC subunits cause hereditary hypertension known as Liddle's syndrome OMIM 177200 ; and the salt-wasting disease pseudohypoaldosteronism type 1 OMIM 264350 ; . Altered sodium absorption was observed in lung diseases such as respiratory distress syndrome Barker et al 1997 ; and pulmonary edema Scherrer et al. 1999 ; . ENaC regulates the liquid balance at birth during the transition from the liquid-filled fetal lung to the air-filled organ Barker et al. 1998 ; whereby all ENaC subunits are regulated at the transcriptional level Talbot et al. 1999 ; . We have analyzed 37 F508del-CFTR homozygous CF sibling pairs at 12p13 and 16p12 markers to learn whether CF disease severity is modulated by SCNN1A, SCNN1B and SCNN1G, encoding the three subunits of ENaC, respectively. The CF sib pairs enrolled within this study have been selected from a set of more than 300 patient pairs on the basis of their homogeneous mutation genotype in the disease-causing gene CFTR and their informative.

S you are aware, as of January, 2005, the province will be expanding eligibility for the publiclyfunded meningococcal C conjugate, pneumococcal conjugate and varicella vaccines. Information below updates you on these developments. We recognize that although these vaccines are publicly-funded, their eligibility criteria fall far short of universal access. This has put parents and physicians in difficult positions, parents pondering the risk-benefit issues of waiting for their child to qualify or purchasing the vaccine s ; commercially, physicians having to at times defend these vaccination policy decisions without full information as to the reasons justifications for eligibility restrictions. The Ontario Medical Association and College of Physicians and Surgeons of Ontario are aware of these issues and are preparing materials for physicians to address these concerns that will hopefully be available in the coming months. Meningococcal C Conjugate Vaccines and Teens Effective January 2005 all Grade 7 students i.e. 12 years of age ; and high school students born between 1986 and 1990 i.e. 15-19 years of age ; will become eligible for publiclyfunded meningococcal C conjugate vaccine. Public Health Departments across the province will be providing schoolbased clinics for these age groups, which in Niagara Region will run from January to May. For Grade 7 students, the meningococcal vaccine will be offered in conjunction with the second dose of the hepatitis B vaccine.

Pharmacokinetic differences exist between ACE inhibitors. However, whether or not these differences result in meaningful clinical differences remains unclear. The onset of action for most of the ACE inhibitors is within 1 hour, with ramipril taking between 1-2 hours. Food slows the absorption of the ACE inhibitors to some extent, with the exception of enalapril and lisinopril. Moexipril and captopril have reported reductions in concentration by 70-80% and 30-40%, respectively, when taken with food. Also, with the exception of captopril and lisinopril, most of the ACE inhibitors are rapidly converted to their active metabolites. Another difference between the ACE inhibitors that has been a topic of debate is the differences in tissue binding between the various agents. For example, ramipril and quinapril both have a high affinity to the ACE enzyme in tissues. It has been postulated that the higher the affinity to the tissue, the tighter the drug is bound, and the longer its duration of action. However, studies have concluded that all ACE inhibitor products can reach maximal efficacy provided they are given in doses high enough to achieve this effect without causing serious side effects.28 Table 3 includes the pharmacokinetic properties for each of the ACE inhibitors.

I going through this just this week with a patient who was placed on an aromatase inhibitor after chemotherapy and in fact now about a year and a half later has resumed periods. So this alarms us because these aromatase inhibitors, while they are very good drugs are not known to be effective in women who have functioning ovaries. A lack of periods is not the same thing as a lack of functioning ovaries so we have to be very careful and endep.

Some antidepressants may be useful in chronic pain because they effectively reduce anxiety and improve sleep without the risks of habit-forming medications. Some people with chronic pain are depressed, and treating the depression may also help reduce the perception of pain. Many people with chronic pain find that antidepressants, along with learning other pain management skills, can help them regain control of their lives and keep their pain under control. ANTIDEPRESSANT SIDE EFFECTS The most common side effects of antidepressants are drowsiness, constipation, dry mouth, and blurred vision. Some people experience nightmares or an increased heart rate. While some people experience minimal side effects, for others, the side effects can be as bad as the pain. It is worth noting that different antidepressants have different side effects, and tolerance to these side effects can develop with use. Some cause more sleepiness, some less. Although some lower sex drive, desire may actually increase as pain, sleep, and mood improve. Some may lower blood pressure, while others raise it. Some increase appetite while others do not. Several may cause dizziness. If a person's pain is helped by an antidepressant but the side effects are troublesome, it may be possible to change medications. The benefit may be retained while reducing the undesirable side effects. Some of these drugs, especially the tricyclic group, can be fatal in overdose and should only be available and prescribed in limited supply. BENEFITS OF ANTIDEPRESSANTS IN CHRONIC PAIN The optimal role for antidepressants in chronic pain is still being defined as research progresses. These qualities seem clear, however. They do not have the potential to cause stomach inflammation and bleeding, as do the anti-inflammatory drugs. They do not seem to interfere with the body's internal pain fighting mechanisms; in fact, they probably strengthen them by increasing the effects of chemical messengers, such as norepinephrine and serotonin, in the nervous system. Many act as sedatives to promote a good night's sleep. Sleep deprivation is often one of the major obstacles in coping with chronic pain. In fact, with severe sleep deprivation, one cannot cope with much of anything. They may help to reduce depression, for example, amil0ride diabetes.

USE OF INSULIN GLARGINE WITH TIGHT GLYCEMIC CONTROL IN CRITICALLY ILL SURGICAL PATIENTS Rayf Aboezz, Marilyn J. Borst, John Fath, Thomas Papadimos, Deana Sievert, Gregory B. Siegel, Martin Ohlinger The University of Toledo College of Pharmacy and Medical College of Ohio, University of Toledo, Medical Center, 3000 Arlington Avenue, Toledo, OH, 43614 rayf.aboezz utoledo Background: Hyperglycemia is common in diabetic and nondiabetic critically ill patients. Using tight glycemic control to maintain normoglycemia 80-110mg dl ; significantly reduces mortality, organ dysfunction, length of stay, and rate of infection in critically ill surgical patients. Hypoglycemia is the main disadvantage. Subcutaneous insulin glargine mimics endogenous insulin action because it has no peak, and has a steady time action profile over 24 hours. Insulin glargine had a flat concentration action profile mimicking continuous subcutaneous infusion of insulin lispro. When compared with insulin NPH, insulin glargine was associated with less nocturnal hypoglycemia and lower post prandial glucose levels in type 2 diabetic patients. No studies have been performed in the use of long acting insulin e.g. insulin glargine, with the tight glycemic control in critically ill patients. Purpose: To compare glycemic control using our current tight glycemic protocol to the current tight glycemic protocol plus insulin glargine in critically ill surgical patients. Methodology: This will be an open label retrospective and prospective study. Ten retrospective critically ill surgical patients greater than 18 years of age receiving mechanical ventilation with tight glycemic control will be compared to ten prospective consecutive patients assigned to tight glycemic control plus insulin glargine for 5 days. The insulin glargine dose will be 70% of the total insulin dose over the previous 24 hours. The dose will be given as a subcutaneous injection at 10: 00 every day with additional insulin given based on the tight glycemic control protocol used by the Surgical Critical Care Service. Primary endpoints will be percentage of blood glucose values higher than 139mg dl and less than 100mg dl. Secondary endpoints include number of dextrose rescue doses per patient days, total number of insulin units per 24 hours, and average blood glucose. Results: Pending. Conclusion: Pending. Learning Objectives: Describe the advantages of tight glycemic control to maintain normoglycemia in diabetic and non-diabetic critically ill patients. Describe the role of insulin glargine in improving tight glycemic control in critically ill patients. Self Assessment Questions: What are the advantages of maintaining normoglycemia in critically ill patients? What is the potential role of insulin glargine in improving tight glycemic control in critically ill patients? and chlorthalidone.
Options as new antifungal agents are developed. The need for new agents stems from the limited utility of amphotericin B, due to its narrow therapeutic index. Although the drug has a broad antifungal spectrum, it is associated with acute and chronic adverse effects; infusion-related fever, rigors, and chills occur in 50% to 72% of treated patients. Low dose corticosteroids e.g., hydrocortisone, 50 to 100 mg i.v. ; may be helpful in the prevention of these symptoms and some patients may develop a tolerance with repetitive dosing. Renal insufficiency is common, affecting as many as 35% to 40% of treated patients. Patients at greatest risk for nephrotoxicity with amphotericin B administration are those: older in age with creatinine or serum creatinine above normal at the beginning of therapy requiring long term amphotericin B therapy who require concomitant nephrotoxic medications aminoglycosides, cyclosporin, tacrolimus, or other immunosuppressants ; . This toxicity is manifested by azotemia, renal tubular acidosis, and potassium and magnesium wasting. It may be severe enough to require dosage reduction, premature discontinuation of amphotericin therapy, or renal dialysis. Low dose dopamine infusions, preinfusion and postinfusion sodium chloride loading, premedication with acetaminophen and or hydrocortisone, and amiloride therapy have been reported to ameliorate these toxicities. Most experts recommend high dose amphotericin B therapy 1mg kg day ; for patients who are profoundly immunocompromised and for patients with documented or suspected invasive mold.
RESULTS Effects of amiloride and bumetanide on cell exit from GO Gl-phase and entry into S-phase In order to evaluate the role ofthe two univalent-cation transporters, stimulated by growth factors, we studied the effect of their inhibitors on cell progression through the GI-phase and entry into S-phase. As a mid-G 1-phase marker we followed the induction of ODC enzyme 26 h after release Haddox et al., 1980 ; . Partially purified FGF induced cell exit from arrest in GO GI, as measured by induction of ODC enzyme activity. ODC induction was partially blocked in the presence of 0.1 mM-bumetanide, and more strongly inhibited by 1 mM-bumetanide Fig. 1 ; . A similar inhibitory effect on ODC induction was found with furosemide, another inhibitor of the Na + K co-transporter results not shown ; . Amkloride 1 mM ; strongly but not completely inhibited ODC induction by FGF Fig. 1 ; . To study the combined effect of the two inhibitors on cell exit from GO G1-phase of the cell cycle, quiescent cells were and tenoretic.

Diuretics may help reduce the risk for dementia and the rate of fractures in elderly people who have taken them for a long time. Diuretic Types. Diuretics come in many brands and are generally inexpensive. Some need to be taken once a day, others twice a day. Three primary types of diuretics exist: Thiazides. Thiazides often serve as the basis for high blood pressure treatment, either taken alone for mild to moderate hypertension or used in combination with other types of drugs. There are many thiazides and thiazide-related drugs; some common ones are chlorothiazide Diuril ; , chlorthalidone Hygroton ; , indapamide Lozol ; , and hydrochlorothiazide Esidrix, HydroDiuril ; . Loop diuretics. Loop diuretics block sodium transport in parts of the kidney; they act faster than thiazides and have a great diuretic effect. It is important therefore to control the medication and avoid dehydration and potassium loss. Loop diuretics include bumetanide Bumex ; , furosemide Lasix ; , and ethacrynic acid Edecrin ; . Potassium sparing agents. Some potassium-sparing diuretics include amiloride Midamor ; , spironolactone Aldactone ; , and triamterene Dyrenium ; . Problems with Diuretics. The loop and thiazide diuretics deplete the body's supply of potassium, which, if left untreated, increases the risk for arrhythmias. Arrhythmias are heart rhythm disturbances that can, in rare instances, lead to cardiac arrest. In such cases, physicians will either prescribe lower doses of the current diuretic, recommend potassium supplements, or use potassium-sparing diuretics either alone or in combination with a thiazide. Potassium-sparing drugs have their own risks, which include dangerously high levels of potassium in people with existing elevated levels of potassium or in those with damaged kidneys. It should be noted, however, that, in general, all diuretics are more beneficial than harmful. Common Side Effects. Common side effects of diuretics are fatigue, depression, irritability, urinary incontinence, loss of sexual drive, breast swelling in men, and allergic reactions. Diuretics can trigger attacks of gout. They may also increase the risk of gastrointestinal GI ; bleeding. Diuretics may raise cholesterol level and, used alone, they have no effect on enlarged heart size hypertrophy ; . Arrhythmias can also occur as an interaction between diuretics and certain drugs, including some antidepressants, anti-arrhythmic drugs themselves, and digitalis.
