OTTAWA, ONTARIO -- A renewable energy group has asked the Canadian government to renounce its ambitious plan to increase the number of installations of ground-source heat pumps. According to Refocus, the international renewable energy magazine, the Earth Energy Society of Canada is concerned that the establishment of unrealistic targets will taint the reputation of the ground-source heat pump industry. The government's Sustainable Development Strategy calls for the installation of 25, 000 commercial ground-source heat pumps in Canada by 2008. In a letter to Energy Minister John Efford, a representative of the Earth Energy Society of Canada wrote, "Natural Resources Canada has no intention of meeting that target; there is no action plan, no strategy, and no support, as there is for wind and ethanol Without an action plan and with no support, that target is doomed to failure and the earth energy industry would prefer not to be labeled as such.

Malabsorbed FA is vigorously fermented by the colonic flora. Compared with equivalent amounts oflactulose, the hydrogen production following FA was ofsimilar magnitude even though the contents ofactual fructose polymers in the product was not 100%. The more prolonged OCITs of FA compared with lactulose is in itself unlikely to influence FA-induced hydrogen production 1 5 ; . larger colonic bacterial hydrogen production after ingestion of the FA substrate compared with lactulose therefore cannot be excluded. Complete or nearly complete fermentation of cereal FA and inulin was demonstrated in rat hindgut 28.

Ability are useful in screening, assessing treatment, and predicting the prognosis.20-21 IP is most commonly assessed by differential urinary excretion of lactulose and mannitol.19 Lactulose is a larger molecule than mannitol, such that a relative increase in the presence of lactulose signifies hyperpermeability. Successful treatment of IBD is matched by a significant reduction in the lactulose: mannitol ratio, indicative of improved permeability.20 Testing was conducted by Great Smokies Diagnostic Laboratories, Ashville, NC. Disease severity was assessed using the Crohn's Disease Activity Index, 21 and each patient completed before and after global symptom assessments. According to practice guidelines developed under the auspices of the American College of Gastroenterology, patient and clinician global assessments correlate well to IBD activity for use in clinical research.22 IP and symptom scores were analyzed for treatment and control subjects separately by T-tests. A P-value of 0.05 was required for statistical significance. In order to standardize starting points and analyze test patients against control patients, percent changes in scores were calculated [% change score1-score2 ; score1x100%], with analysis by ANOVA. Study 2: HIV The site for the study was a large urban private medical practice with approximately 400 HIV-positive patients. Thirty-two patients were selected over a 2-month period, based on the following inclusion criteria: HIV-positive, ability to provide informed consent, ability to adhere to daily supplement regimen, life expectancy of at least 6 months, age greater than 18 years, absence of any OIs, compliance with uninterrupted HAART for at least 6 months, and viral load of less than 50 copies mL; and the following exclusion criteria: female gender, life expectancy of less than 6 months, opportunistic malignancy requiring systematic chemotherapy within 30 days of study entry, the presence of any OIs, or concurrent use or prior use of anabolic agents appetite stimulants corticosteroids within 30 days of study entry. The outcome-based study design was randomized, double-blind, and placebo-controlled. Patients were evaluated monthly for a total study duration of 5 months. The treatment group n 18 ; received the fish peptide supplement, while the placebo group n 14 ; received the barley placebo, 2 x 500mg capsules TID. Patient questionnaires and clinician interviews were used to assess changes in intestinal symptoms and quality-of-life issues, while routine blood testing was used to identify any changes in disease status. The use of questionnaires for evaluating quality-of-life issues related to HAART and nutritional support has been documented.23 Interviews and blood tests were conducted monthly. Statistical analysis was performed using T-tests.

Acute HCV infection is the initial infection period of the hepatitis C virus. Most people will develop few or mild symptoms, but some will experience fatigue, nausea, vomiting, and loss of appetite. The goal of nutrition therapy during this stage is to provide adequate nutrition to help the liver cells heal and regenerate. This means getting enough calories, protein, and micronutrients vitamins and minerals ; to maintain weight. In some cases, a low fat diet is helpful. Avoid alcohol. Chronic HCV infection pre-cirrhotic ; can extend over many years, during which mild or intermittent symptoms may occur. Chronic inflammation can ultimately result in liver damage, fibrosis, steatosis fatty liver ; , cirrhosis, or cancer. Eating a nutritious diet with moderate physical activity is recommended. No specific dietary modifications are required unless symptoms are present, which should be addressed individually see Part I of this article ; . Chronic HCV infection cirrhosis ; develops as fibrosis and irreversible scarring that progressively damage the liver. Most people with cirrhosis have compensated disease with few symptoms, in which case nutritional guidelines do not change. However, cirrhosis can gradually become decompensated, which results in numerous metabolic and nutritional complications. Malnutrition can have an independent negative effect on disease progression and survival. The principle causes are metabolic abnormalities glucose intolerance and breakdown of the body's proteins ; , inadequate dietary intake because of loss of appetite and gastrointestinal symptoms, and maldigestion or malabsorption, especially of fat. Hepatic encephalopathy HE ; , or impaired mental function, may occur in advanced liver disease when scar tissue prevents normal flow of blood through the liver. The damaged liver has difficulty processing the products of protein metabolism, especially ammonia, leading to protein intolerance. Prolonged low protein diets are no longer used to treat HE, but they may be used briefly in conjunction with medications. Lactulose is often prescribed to induce two to three soft bowel movements daily, which help clear the ammonia.
The effects of alcohols on lactose have been studied extensively during the last few years 2, 3, 4, ; . Among alcohols, methanol was most studied. Alcohols are suitable for removal of water from c~-lactose hydrate to produce crystals of stable anhydrous lactose. Lactose also may be crystallized from aqueous-alcoholic solutions. The c~1 3 ratio of the lactose precipitate from aqueous-alcoholic solutions depends on the conditions of crystallization; however, pure 3-1actose cannot be obtained by this method 3, 5 ; . Alkali causes isomerization of reducing sugars. Lactose is converted into lactulose followed by the rapid degradation of the latter into a and leuprolide.
Would have resulted in insignificant changes to the data. Lactulose recovery was significantly greater at 2.9310.67 versus 0.1790.11% between TPN and enteral groups, respectively. Similarly, PEG 4000 recovery was 12.784.11 versus 0.96.24% between the same groups. In order to assure pre- and post-intestinal factors did not affect recovery of the paracellular markers, we used mannitol, absorbed via the transcellular route, as a controlling factor and recovery was notably reduced in the TPN group when compared to the enteral group, 52.993.86 versus 68.353.94%, respectively. Mannitol is often used with lactulose to correct for the latter's recovery, as the two markers are not metabolized before or in the small bowel, empty similarly from the stomach, and are cleared the same from the kidneys 5 ; . When lactulose mannitol ratios were used to corroborate recovery data, the results were no different 0.05040.0100 vs. 0.00230.0014, TPN vs. ENT ; . Intestinal inflammation Figures 3 ; Myeloperoxidase activity, expressed as millunits of activity per milligram of protein mUmg protein-1 ; , was used as an indirect indicator of inflammation. One unit of activity equals one micromole of substrate catalyzed in one minute at 25C. Our findings showed a significant increase in enzyme activity in the proximal jejunum, 4.630.47 vs. 2.160.39 mUmg protein-1, and a trends towards increased activity in the distal ileum, 5.660.58 vs. 4.030.66 mUmg protein-1 p 0.08 ; , of the TPN group when compared to controls. Weak, but significant, correlation estimates were found for myeloperoxidase activity and recovery of lactulose and PEG 4000, R2 0.32 p 0.003 ; and R2 0.38 p 0.003 ; , respectively, when the animals were assessed collectively. No such correlation was found for bacterial translocation and either myeloperoxidase activity or permeability. Bacterial translocation Table 3.

Discussion Urine samples from patients with severeburns present an analytical challenge tothe clinical chemist. Our experience has been that many analytical assays of urine from normal and sicksubjects cannot necessarily be appliedto urine from burn patients.he enzymatic T assay of urinary lactulose is a prime example. The method outlinedby Behrens et al. 6 ; involvesan enzymatic hydrolysis oflactulose to fructose and galactose, followed the conversion fructose glucose by of to 6-phosphate. Lactulose ismeasured indirectly by converting glucose 6-phosphate to gluconate 6-phosphate and monitoring at 340 nm the reduction of NADP. We have found that urine from patients with severe burns frequentlycontainscompounds that interfere with the enzyme assaysused to determinelactulosen i urine. Although filtration ofthe urine througha cationexchangecolumn removes these compounds, this procedure is time-consuming and increases the chance of dilution errors. Moreover, theenzymaticassay forman.
Lactulose reaches the colon unchanged, where the bacteria of the intestines metabolise it, producing a number of short chain fatty acids. This process initiates a large number of effects in the gastrointestinal tract: Lactulose Lactulose promotes the inhibits development of and levemir.
The amount of starch which escapes digestion in the human small bowel each day is difficult to quantify. Table IX shows results from a series of ileostomy studies in humans. From the table it will be seen that cereal starches are on the whole well digested, with only 2 to 3% escaping in ileostomy effluent, unless the starch has been processed and retrogradation has taken place RS3 ; . The same is true for freshly cooked potato, but once cooled 12% becomes amylase resistant. Banana starch escapes digestion almost entirely. In another series of ileostomy studies, CHAPMAN et al. [74] found only 2.4% 1.9 g ; of starch malabsorbed from meals of wheat and potato starch, while WOLEVER et al. [79] found total carbohydrate passing to the large intestine after test meals to be 11% 9.5 g ; from white bread, 8% 7.7 g ; from wholemeal bread and 18% 20.8 g ; from red kidney beans. In studies of healthy people intubated so that direct measurement of carbohydrate passing through the ileum could be made, STEPHEN et al. [80] found that 6% and 9% 2.1 and 4.8 g ; of the carbohydrate from two mixed meals were malabsorbed. A number of studies of starch digestion have relied on the appearance in breath of hydrogen generated during fermentation as an index of starch breakdown. The amount of hydrogen in breath is compared to that released during fermentation of a known amount of carbohydrate such as lactulose and, from this ratio, quantitative data for starch absorption are derived. For example, LEVITT's group, in a series of studies using breath hydrogen as a marker of carbohydrate.
Probably all forms of hepatic encephalopathy have their basis in a disorder of nitrogen metabolism. Ammonia NH3 ; is formed in the bowel by the action of urease-containing organisms on dietary protein and is carried to the liver in the portal circulation. However, the NH3 fails to be converted to urea because of hepatocellular disease or portalsystemic shunting of blood, usually both. As a result, excessive amounts of NH3 reach the systemic circulation and interfere with cerebral metabolism in a way that is not fully understood. The clinical syndrome of hepatic coma consists essentially of a disorder of consciousness, ranging from confusion to stupor and coma, accompanied by a characteristic movement disorder and EEG abnormality. The disorder of movement, loosely referred to as a "flapping tremor, " is in reality an intermittency of sustained muscle contraction asterixis ; . The EEG changes occur early in the evolution of the syndrome and take the form of synchronous bursts of high-voltage slow delta ; waves, which appear first in the frontal regions and then replace all normal activity as coma deepens. A fluctuating rigidity of the limbs, reflex sucking and grasping, and sometimes Babinski signs and focal or generalized seizures round out the clinical picture. The blood NH3 concentration, measured in arterial blood samples, usually exceeds 200 g dL and corresponds roughly to the depth of stupor and coma. Hepatic coma is often precipitated by high protein intake or gastrointestinal hemorrhage. Hypoxia, hypokalemia, electrolyte depletion, and excessive diuresis are contributory factors. Measures that lower the blood NH3--low-protein diet, oral neomycin and neomycin enemas to reduce urease-producing bacteria in the gastrointestinal tract ; , and the use of lactulose which acidifies the bowel contents ; --are of therapeutic benefit and lend support to the ammonia intoxication hypothesis. In the Reye syndrome of children, an acute viral infection varicella, influenza B, and others ; precipitates the rapid development of fever, vomiting, an enlarging fatty liver, convulsions, stupor and coma, with decorticate or decerebrate rigidity, loss of brainstem reflexes, and death, all within a few days. The CSF is under high pressure but is acellular. NH3 levels may exceed 500 mg dL. SGOT levels are also high several thousand units ; . At autopsy the liver cells are filled with fine droplets of fat, which are also present in renal tubules, myocardium, and skeletal muscle fibers. The brain is swollen and cerebral and cerebellar herniations are evident, with only secondary hypoxic changes. Control of fever, ventilation, osmolality of blood, electrolyte balance, and blood NH3 before coma develops has resulted in a significant reduction in mortality. The control of intracranial pressure by methods outlined in Chap. 29 may improve outcome. In young children, salicylates given for a respiratory infection are believed to precipitate this syndrome. Knowledge of this effect and avoidance of aspirin are prob and levetiracetam!

Are specific, IO6strain SJ162 cells Lac-Lu- ; cells were spread onto a set of LUG plates at 30" and allowed to grow overnight at the expense of the glycerol to form a lawn of -2 X lo9cells. On day 1 the day after plating ; , cells were washedfrom a subset of those plates, concentrated, and spread onto Lac medium to determine the frequency and distribution ofClass I Lac%- ; mutants. After several days incubation, during which time Class I1 LacfLuf ; adaptive mutants appear as colonies on the LUG plates, the colonies were eliminated. The remaining cells were washed from the plates, concentrated, and spread onto Lac medium to determine the frequency and distribution ofClass I Lac'Lu- ; mutants. If the frequency and distribution of Class I Lac + Lu- ; mutants remained unchanged, this wouldbe strong evidence that adaptive mutations are specific. Survival of Class I Lac'Lu- ; mutants during selection on lactulose: During prolonged selection for lactulose utilization on LUG medium, Class I1 Lac'Lu + ; mutations are advantageous, whereas Class I Lac'Lu- ; mutations are expected to be neutral. study the specTo ificity ofadaptive mutagenesis by determining themutation rate at the unselected Class I site during selection for mutations at the Class I1 site, it is necessary to know that Class I mutations are not deleterious during selection on lactulose. A Class I Lac'Lu- ; mutant of strain SJ162 was spread onto LUGplates at 1.2 X lo6 cells per plate. Plugs were removed from the plates daily, suspended in sterile buffer, and plated to estimate the number of viable cells. Over a period of 8 days the numberof viable cells remained unchanged the slope of viable cells us. time was 0.51 2 5.0 day", and p, the probability that the slope was indistinguishable from zero was 0.82 ; . This result suggests that any unselected Class I Lac'Lu- ; mutants that arose during selection on lactulose would survive and be detected. Do Class I mutants occurduring prolonged selection on lactulose? About lo6 SJ162 cells were spread onto each of 204 LUG plates and incubated at 30". The following day Day the cells were washed 1 ; from 32 plates, aliquots from 10 of the samples were diluted andplated to determine the numberof viable cellsper plate. Each sample was concentrated by centrifugation and plated onto a Lac plate at 37" to determine the distribution of Class I Lac + Lu- ; mutants per plate. There was a lawn of 2.9 2 0.4 X lo9 cells per LUG plate, and Figure 2B shows the distribution of Class I Lac'Lu- ; mutants as determined by counting the number of colonies on the Lac plates after 2 days incubation. Those 32 plates constitute a Luria-Delbruck fluctuation test LURIA and DELBRUCK 1943 ; , and theClass I mutation rate during the growth of those cultures from 10" to 2.9 X lo9 cells can be estimated from Po, the proportion of plates in which there were no Class I Lac'Lu- ; mutants. POwas 0.438, thus the average number of mutations per plate was -ln Po ; 0.83, which is amutation rate 2.8 X 10"' per cell division.
The Journal of Immunology Fig. 3C ; . The sequence identity in the minimal promoter region is 67%. However, only a minority of sites bound by transcription factors were coordinate on the two promoters. One of these coordinate transcription factor-binding regions was identified as site A in the promoters of both KIR2DL4 and KIR3DL1. The sequences at these sites are highly similar, but no specific binding was observed when probes of these sequences in isolation were used in EMSAs data not shown ; . This is possibly due to weak or cooperative binding of transcription factors to these sites that would be disrupted during the EMSA procedure. Transcription factors with a high score potential to bind KIR2DL4 site A include AREB-6 and SMAD-3, and AREB-6 has a potential binding site around KIR3DL1 site A. The sequence similarities of the KIR2DL4 and KIR3DL1 A sites make them good candidates as sequences binding a common KIR transcription factor. The other conserved binding region is that of KIR2DL4 site E and the gene-proximal part of KIR3DL1 site D. The sequence at these sites corresponds to a potential RUNX AML transcription factor-binding site. The functional activity of these sites is supported, as the 108 to 98 deletions of each KIR promoter bisected these sites and reduced the activity of each promoter Fig. 1, C and E ; . The remainder of the sites identified by DNase I footprinting are disparate between the KIR3DL1 and KIR2DL4 promoters. Site B of KIR2DL4 includes strong candidate sequences for binding Nkx, AP-1, TCF-2, MYC-MAX, and GATA-3. A lower scoring sequence is present for IFN regulatory factor 2 IRF-2 ; binding. The strongest candidates for binding KIR2DL4 site C are members of the AP-1 family. KIR2DL4 site D corresponds to a CREB ATF or an AP-1 binding site, and KIR2DL4 site F is a potential binding site for RUNX family members, AP-1, estrogen receptor, and ROR -1. In the KIR3DL1 promoter, site B is a potential binding site for TCF-2, AP-1, and the estrogen receptor. Potential factors binding to KIR3DL1 site C include STAT, Ets family members, and YY-1. The gene distal part of KIR3DL1 site D is a potential binding sequence for CREB and the estrogen receptor, and the KIR3DL1 site E is a binding sequence for E2F, NF-1, and SP-1, although it may be directly involved in core promoter activity as a TF IIB recognition element see below ; . KIR2DL4 site G and KIR3DL1 site F are coordinate with the transcription initiation sites Another marked difference between the two KIR promoters was observed in the positions of the final DNase I-protected sites. These sites, KIR2DL4 site G, and KIR3DL1 site F, corresponded with the 5 ends of cDNAs generated by a 5 RACE analysis Fig. 4 ; . This coincidence of the transcription initiation sites with the transcription factor-binding sites suggests that they are generated by components of the transcription initiation apparatus. In support of this role, neither KIR2DL4 site G nor KIR3DL1 site F in isolation bound YT-Indy nuclear extracts with sequence specificity in EMSA data not shown ; . The 5 cDNA ends of the KIR transcripts generated by 5 RACE were heterogeneous, but tightly clustered just upstream of the translation initiation site. Heterogeneous transcription start sites are often present in promoters without TATA boxes 38 ; . A potential TATA box AAATAAC ; is present at positions 65 to 59 the KIR3DL1 promoter. Its sequence differs substantially from the canonical TATAAA, although certain divergent sequences can act as TATA boxes 39 ; . A sequence GGGCGCC ; corresponding to a TF IIB recognition element BRE ; is present immediately upstream of this TATA box within KIR3DL1 site E. These elements serve to increase the affinity of TF IIB and therefore may confer functionality to the KIR3DL1 TATA box 40 ; . No consensus TATA box was observed in the KIR2DL4 promoter, but.

Reference to Disturbance of Sexual Function. New England J. Med. 245: 121 July 26 ; , 1951. The secondary effects of sympathectomy with especial reference to sexual functions was studied by analysis of questionnaires from 161 patients. Procedures included lumbodorsal splanchnicectomy, lumbar sympathectomy, transthoracic sympathectomy and splanchnicectomy, and upper dorsal sympathectomy. Bilateral lumbar sympathectomy led to a change in sexual function in 63 per cent of the patients so treated. Anatomic variations from patient to patient are felt to be responsible for unpredictable responses to the various procedures em and lantus.

Extraordinarily strong, this peptide was assumed to be abundantly expressed in hemocytes. Among RNAs from various tissues of the horseshoe crab, hepatopancreas, heart, stomach, intestine, muscle, brain, and coxal gland ; , RNA from the heart showed an intense band with the same mobility as that of the hemocytes. RNA from the brain also showed a relatively intense band. The other tissues examined showed a faint band with longer exposure of the film. It was not clear, however, whether these bands were derived from small amounts of contamination by hemocytes in the dissected tissues or whether they actually were expression of small amounts of tachyplesin. Southern Blot Analysis-The gene of the tachyplesin precursor was examined by Southern blot analysis of the XTPNICl insert used for Northern blotting Fig. 5 ; . The genomic DNA was completely digested by four different restriction enzymes EcoRI, HindIII, PstI, and XM ; , none of which digested the obtained cDNA. The relatively large bands strongly hybridized with the probe. In the EcoRI digest, three bands, approximately 11.0, 9.5, and 8.5 kbp, were observed. Three bands 17.0, 14.5, and 11.0 kbp ; in the Hind111 digest, two bands 29.0 and 11.0 kbp ; in the PstI digest, and two bands 18.5 and 2.5 kbp ; in the XbaI digest were also observed, respectively.

Although commonly considered to be "non-absorbable" in the human gastrointestinal tract, some lactulose is in fact absorbed 6, 7 ; . Absorption of lactulose has been demonstrated, e.g., from the human mouth and from rat small intestine 6 ; . Indeed, Laker and Menzies 7 ; exploited lactulose absorption as an indicator of intestinal permeability and demonstrated its renal excretion. The peak concentration of lactulose in plasma was 24 mg L after ingestion of 10 g lactulose 7 ; . Our patient received 180 g, almost 20 times as much, daily for several days. Her estimated peak plasma lactulose of 10 g L, the presence of renal impairment, appears to be consistent with the report of Laker and Menzies 7 ; . Evidently, absorption of lactulose produces a hyperosmolar state and an artifactual increase in serum creatinine, mimicking pre-renal azotemia. An increase of creatinine in serum of a patient with hepatic coma the type of patient treated with lactulose ; also suggests the onset of an hepatorenal syndrome. For these reasons, the artefactua.l increase of serum creatinine may be especially misleading. Alternative methods for creatinine measurement must be considered in patients who are undergoing treatment with lactulose.
| In amplitude of the motor readiness potential generated by medial and lateral premotor cortex ; after treatment of normal subjects with haloperidol. Reduced D2 antagonism in the nigrostriatal dopaminergic system might enhance frontal cortical activity by reducing inhibitory output from globus pallidus 37, 38 ; . Reduced D2 antagonism in the mesoneocortical system might disinhibit pyramidal cell activity in frontal cortex by inhibiting -aminobutyric acid ; GABAergic interneuronal activity. GABAergic interneurons normally act to inhibit pyramidal cell activity, and they are the main cellular site of D2 receptors in frontal cortex 39 however, it is currently controversial whether dopamine has excitatory or inhibitory effects on these cells 4043 ; . Alternatively, it is possible that substitution of risperidone might have modulated frontal neuronal activity by a serotonergic mechanism. Risperidone has greater antagonist affinity for postsynaptic 5HT2A receptors than typical antipsychotic drugs have, and 5HT2 receptors mediate the excitatory effects of ascending projections from the brainstem raphe nuclei on GABAergic interneurons in frontal cortex 39 ; . Thus substitution of risperidone might act to disinhibit pyramidal cell activity, and so increase functional response, by blocking serotonin effects on inhibitory interneurons. A third possible mechanism is based on an interaction between dopaminergic and serotonergic systems. Serotonin has been shown to have an inhibitory effect on presynaptic dopamine release 44, 45 ; , and 5HT2 receptor antagonism has been shown to cause increased dopamine release in animal models 46 ; . Serotonergically enhanced dopamine release might in turn affect neuronal activity by either one or both of the D2 receptor-based mechanisms already described, or by D1 receptors, which are located preferentially on pyramidal cell bodies and have a critical role in optimizing frontal cortical response to working memory tasks 47 ; . Thus dopaminergic and or serotonergic effects of substituting risperidone for typical antipsychotic drugs might directly cause enhanced functional activation of prefrontal and medial premotor areas, which are known to receive a rich dopaminergic input from midbrain nuclei in the macaque monkey 48 ; . Associated changes in functional response of posterior parietal cortex were not hypothetically predicted, and dopaminergic afferentation of this cortical area has not been so well characterized in nonhuman.
Ing long-term PEG therapy did not have any adverse effects on renal function, electrolyte levels, serum albumin levels, and osmolality. Thus, long-term PEG therapy does not adversely affect fluid and electrolyte balance despite improvement in stool frequency and consistency. Nine patients had minor elevations of ALT levels, and 3 patients had minor elevation of aspartate aminotransferase levels at one point during the study. The elevation was only a few points above the reference range for our laboratory and completely resolved in all but 1 patient when remeasured while still receiving therapy. No symptoms or signs of liver disease were present in these patients. A recent study14 on liver function tests indicates no need for further evaluation if mildly elevated levels of aminotransferase are within the reference range on retesting. Due to these reasons, we believe that the transiently abnormal ALT levels were clinically insignificant and unrelated to PEG treatment. Although we did not see any major adverse effects in our study, the upper limit of the 95% confidence interval of point estimate of zero for adverse effects is approximately 4% in a sample size of 83 patients. Therefore, a study of a larger number of patients followed up for a longer duration of treatment would be required to ensure the absence of rare adverse effects. Short-term PEG therapy in adults 2 weeks ; and children 3 days ; has shown no significant change in laboratory evaluation results consisting of electrolyte profile, renal function tests, and serum chemistry analysis.6, 15 Postmarketing safety information from the manufacturer reports rare allergic reaction to PEG in the form of rashes, but no other serious adverse effects have been reported in children John McGowan, BA, Braintree Laboratories, e-mail communication, January 29, 2003 ; . Studies3, 16 in human volunteers indicate that systemic absorption of PEG is minimal estimated at 0.06% ; and renal excretion is high. Therefore, systemic toxicity of PEG is unlikely.3, 16 There are several effective medications available for long-term treatment of constipation in children, including milk of magnesia, lactulose, and mineral oil.1 However, these medications have either poor palatability or adverse effects such as abdominal pain, flatulence, or anal leakage, which may limit patient acceptance and compliance.8, 9 Most children in our study had tried other laxatives before. They all preferred PEG to other laxatives because of its palatability. Therefore, compliance with PEG and patient acceptance was excellent. Efficacy of PEG therapy for children with constipation and encopresis has been reported before.8-10 In one study, milk of magnesia was as effective as PEG 67% vs 61% ; in children with constipation and encopresis who received these therapies for 12 months.9 However, 33% of children refused to take milk of magnesia, whereas none refused PEG.9 In another crossover study, PEG therapy was as effective as lactulose for the treatment of constipation in children in a 2-week trial, but PEG was preferred by children compared with lactulose.10 In summary, PEG seems to be a safe medication for long-term treatment of constipation in children. It should be considered a favorable option for long-term therapy for children, particularly because of excellent patient acceptance.
