Oral V2 receptor antagonist (RWJ-351647) in patients with cirrhosis and ascites: a randomized, double-blind, placebo-controlled, single ascending dose study.

BACKGROUND: RWJ-351647 is a selective V2 receptor antagonist that inhibits vasopressin-induced water reabsorption in the kidney. AIM: To investigate the safety and tolerability of RWJ-351647 compared with placebo after single oral dose administration to patients with cirrhosis and ascites, on a stable treatment with furosemide and spironolactone. METHODS: Single oral doses of 1, 2 and 5 mg of RWJ-351647 were administered to 24 patients with ascites on stable concomitant diuretic treatment. RESULTS: RWJ-351647 had a tmax of 1 to 1.1 h and mean half-life of 10.4-17.4 h. There was no affect on the pharmacokinetics of concomitant diuretics. Increases in cumulative urine volume and free water excretion, and a decrease in urine osmolality were noted in a dose-dependent manner reaching the statistical significance at the 5-mg dose. Four patients exhibited a decrease of > 2 kg in weight in the 24 h after dosing. RWJ-351647 was well tolerated, with no evidence of a dose-related increase in adverse events when compared with placebo. No changes in either serum chemistry or plasma AVP (arginine vasopressin) and renin levels were observed despite the observed aquaresis. CONCLUSION: RWJ-351647 is an effective aquaretic causing dose-dependent increases in urine output and free water clearance, when co-administered with conventional diuretics in patients with cirrhosis and ascites.

A retrospective evaluation of the eruption of impacted permanent incisors after extraction of supernumerary teeth.

AIMS: Delayed eruption of teeth may be caused by the presence of one or more supernumerary teeth. The purpose of this study was to evaluate findings, predisposing factors and differentiate different techniques used that affect the outcome following removal of supernumerary teeth. A comprehensive literature review was also undertaken. METHODS: A longitudinal retrospective study was carried out at the Royal Liverpool Children's Hospital. A total of 120 patients were identified from the general anesthesia records that had supernumeraries extracted. Only 43 cases had delayed eruption of teeth caused by supernumeraries. The pre and post extraction record data collected were the gender, radiographic assessment, position of the supernumerary, age at time of referral and extraction of the supernumerary, age at time of eruption of the impacted tooth and the orthodontic and surgical management. RESULTS: The mean age of referral was 9.1 years with a male to female ratio of 4.4:1. There was a greater predilection for supernumeraries to be on the left side and be positioned palatally. Tuberculate type supernumeraries were the most frequent followed by the conical type. Spontaneous eruption of the impacted tooth occurred in 49% of cases. Eruption of the impacted tooth within eighteen months following removal of the supernumerary was observed in 91% of cases. The chronological age and space availability were the two factors that were critical in determining if eruption was spontaneous following removal of the supernumerary. CONCLUSIONS: The findings of this study reiterates the fact that given early referral, sufficient space and time, the majority of teeth prevented from erupting by a supernumerary tooth would erupt spontaneously following removal of the supernumerary alone. Randomized multi-centre prospective studies are suggested.

[Diastolic dysfunction in liver cirrhosis].

The presence of a hyperdynamic circulation in cirrhotic liver is currently a well established concept. The first studies of cardiac function in patients with cirrhosis suggested the existence of an alcoholic cardiomyopathy. More recently, altered left ventricular response to physiological and/or pharmacological stimuli in patients with post-viral liver cirrhosis has been established, and clinically insignificant diastolic cardiac function has also been observed. Neurohumoral hyperactivity and hyperdynamic circulation, which are associated with chronic exposure to the cardiodepressant substances present in advanced liver disease, play a decisive role in the genesis of this process. The lack of relaxation of the left ventricle and alteration in the pattern of transmitral flow, both of which are characteristics of this clinical entity, are easily detected by echocardiography. The growing evidence of diastolic dysfunction in liver cirrhosis, particularly in decompensated cirrhosis, suggests the clinical importance of the problem, thus introducing the concept of "cirrhotic cardiomyopathy". Greater insight into this phenomenon could help to decrease cardiovascular risk, especially during maneuvers commonly used in the treatment of the complications of liver cirrhosis, such as paracentesis, transjugular intrahepatic portosystemic shunt stent implantation, and liver transplantation.

Sepsis in cirrhosis: report on the 7th meeting of the International Ascites Club.

Sepsis is a systemic inflammatory response to the presence of infection, mediated via the production of many cytokines, including tumour necrosis factor (TNF-), interleukin (IL)-6, and IL-1, which cause changes in the circulation and in the coagulation cascade. There is stagnation of blood flow and poor oxygenation, subclinical coagulopathy with elevated D-dimers, and increased production of superoxide from nitric oxide synthase. All of these changes favour endothelial apoptosis and necrosis as well as increased oxidant stress. Reduced levels of activated protein C, which is normally anti-inflammatory and antiapoptotic, can lead to further tissue injury. Cirrhotic patients are particularly susceptible to bacterial infections because of increased bacterial translocation, possibly related to liver dysfunction and reduced reticuloendothelial function. Sepsis ensues when there is overactivation of pathways involved in the development of the sepsis syndrome, associated with complications such as renal failure, encephalopathy, gastrointestinal bleed, and shock with decreased survival. Thus the treating physician needs to be vigilant in diagnosing and treating bacterial infections in cirrhosis early, in order to prevent the development and downward spiral of the sepsis syndrome. Recent advances in management strategies of infections in cirrhosis have helped to improve the prognosis of these patients. These include the use of prophylactic antibiotics in patients with gastrointestinal bleed to prevent infection and the use of albumin in patients with spontaneous bacterial peritonitis to reduce the incidence of renal impairment. The use of antibiotics has to be judicious, as their indiscriminate use can lead to antibiotic resistance with potentially disastrous consequences.

Sustained response after a 2-year course of lamivudine treatment of hepatitis B e antigen-negative chronic hepatitis B.

Lamivudine has demonstrated efficacy for the treatment of hepatitis B e antigen-negative chronic hepatitis B (e-CHB). However, treatment withdrawal after 1 year has been associated with a high rate of relapse while long-term treatment is associated with increasing risks of drug resistance. We report our treatment experience of 50 Chinese-Canadian patients with e-CHB. All patients received lamivudine for 2 years. Treatment was withdrawn at month 24 in patients who had undetectable hepatitis B virus (HBV) DNA by PCR and normal aminotransferases during the second year of therapy. All patients had HBV genotype B or C. Biochemical response at months 6, 12 and 24 was 74%, 71% and 66%, respectively. HBV DNA was undetectable at months 6, 12 and 24 by hybrid capture and PCR assays in 100%, 92% and 86%; and 94%, 88% and 74% patients, respectively. The cumulative rates of genotypic resistance (GR) after 1 and 2 years were 15% and 25%, respectively. Four (44%) patients with GR experienced a hepatitis flare. The probability of clinical and virological relapse 6, 12, and 18 months after treatment withdrawal were 12% and 30%, 18% and 50%, and 30% and 50%, respectively. Reinstitution of lamivudine resulted in prompt virological and biochemical responses. Our study demonstrates that a sustained response can be achieved after a 2-year course of lamivudine in a subset of patients with e-CHB.

Suicidal mercury injection into the upper limb: a case study.

We report a rare case of self-injection of mercury into the subcutaneous tissue of the upper limb. A multi-disciplinary management approach was adopted including cooperation between toxicologists, orthopaedic surgeons, radiologists and environment safety personnel. Surgical removal of mercury under radiological screening and systemic intoxication treated by chelating agents, namely dimercaprol and succimer. Serial serum and urine mercury levels showed an initial rise despite surgical removal and returned to normal after a prolonged period of time. Safety precautions were taken during surgery to avoid inadvertent intoxication of staff. Contamination of the operation theatre was monitored by the amount of mercury vapour released into the air. All personnels involved in the management of the patient did not show any evidence of mercury intoxication.

Small-cell carcinoma of the cervix: fourteen years of experience at a single institution using a combined-modality regimen of involved-field irradiation and platinum-based combination chemotherapy.

PURPOSE: To determine the efficacy and toxicity of a combined-modality regimen of irradiation with platinum-based combination chemotherapy in small-cell carcinoma of the cervix (SCCC). PATIENTS AND METHODS: Thirty-four patients with SCCC were seen and treated at the British Columbia Cancer Agency between May 1988 and November 2002. Two protocols were used, SMCC (May 1988 to December 1995) and SMCC2 (January 1996 to November 2002). Both protocols used cisplatin, etoposide, and involved-field irradiation (essentially pelvis plus or minus para-aortics) with concurrent chemotherapy. In addition, SMCC2 included carboplatin and paclitaxel, and the para-aortics were irradiated routinely. RESULTS: Thirty-one patients received either SMCC (n = 17) or SMCC2 (n = 14), and three patients did not (disease too extensive, n = 1; patient refusal, n = 1; and alternative regimen, n = 1). For the 31 patients treated on one of the protocols, the 3-year overall and failure-free survival (FFS) rates were 60% and 57%, respectively. The results were equivalent for SMCC and SMCC2. Radiologic stage was the only independent predictor for FFS (80% at 3 years for stage I and II patients v 38% at 3 years for stage III and IV patients). Distant failure (28%) was the most common cause of failure, with local failure occurring in 13% of patients. The switch to SMCC2 did not improve efficacy but did lessen the toxicity. CONCLUSION: SCCC can be successfully treated in approximately 55% of patients with a combination of irradiation and platinum-based chemotherapy. Disease extent predicts for chance of curability.

Radiation induced mucositis: co-ordinating a research agenda.

AIMS: A one-day workshop was hosted by the Symptom Control Committee of the National Cancer Institute of Canada, Clinical Trials Group (NCIC-CTG), in conjunction with the October 2002 annual meeting of the Canadian Association of Radiation Oncologists in Toronto, Ontario. The primary intention of the workshop was to direct the future research agenda of the Symptom Control Committee. Large group presentations were held initially to review the contemporary research issues of four selected areas of interest: fatigue, brain metastasis, bone metastasis and radiation-induced mucositis. Panel members were then charged with the identification of specific research proposals that could be considered for further development. Research questions were to be clinically relevant and currently appropriate. Any additional information needed before the launch of any potential trial was also requested. In this paper, we will review and summarise the outcomes from the radiation-induced mucositis sessions. MATERIALS AND METHODS: Thirty-four participants participated in the large group sessions and contributed to one of four panel discussions on selected supportive care issues relevant to radiation oncologists. RESULTS: Three potential and non-overlapping research questions were identified; two involving mucositis management in patients receiving radical radiation for head and neck cancer, and a third for patients with advanced lung cancer undergoing combined radiation and chemotherapy and at risk for the development of symptomatic oesophagitis. CONCLUSION: The workshop successfully identified three potential research questions. The large group and the smaller panel discussions successfully established consensus on important aspects of future study designs. The current 'standard of care', appropriate experimental treatments, primary outcomes of interest and study population parameters were each important issues that were discussed. The importance of developing meaningful biological assays was reviewed, as was the need to ensure the appropriate storage of biological samples from patients for future study.

Ectopic synaptogenesis during retinal degeneration in the royal college of surgeons rat.

Rod photoreceptor-specific mutations cause ectopic synapses to form between cone photoreceptor terminals and rod bipolar cell dendrites in degenerating retinas of rhodopsin transgenic (P347L) pigs and retinal degeneration mice. Since the mutations occur in rod photoreceptor-specific genes in these two models, it is not known if ectopic synaptogenesis occurs specifically due to some rod photoreceptor cell-autonomous properties of a mutation or as a general consequence of photoreceptor degeneration. In the Royal College of Surgeons (RCS) rat, a mutation in the receptor tyrosine kinase gene, Mertk, causes failure of the retinal pigment epithelial (RPE) cells to phagocytose shed photoreceptor outer segments; subsequently, both rod and cone photoreceptors die. The non-phagocytic phenotype of the RCS rat is RPE cell-autonomous and the photoreceptors degenerate secondarily. Here we show that in 35-day-old RCS rats, where a majority of rod and cone photoreceptors remained, rod bipolar cell dendrites had abnormal (flat-contact type) synaptic contacts with rod and cone terminals. Demonstration of ectopic synapses in the RCS rat suggested that ectopic synaptogenesis could occur as a result of photoreceptor degeneration, even when the rods and cones were developmentally normal. This further supported the hypothesis that ectopic synaptogenesis may be a common step in the disease progression of different forms of retinal degeneration that include photoreceptor death as a feature, such as retinitis pigmentosa.

Maternal and neonatal factors influencing premature birth and low birth weight in Australia.

This study identified the influences of neonatal and maternal factors on premature birth and low birth weight in New South Wales, Australia. Bivariate and multivariate analyses were used to explore the association of selected neonatal and maternal characteristics with premature birth and low birth weight. The findings of this study showed that premature birth and low birth weight rate significantly varied by infant sex, maternal age, marital status, Aboriginality, parity, maternal smoking behaviour during pregnancy and maternal hypertension. First-born infants, and infants born to mothers aged less than 20 years, or who were single, separated/divorced, Aboriginal or who smoked during the pregnancy, were at increased risk of being premature or of low birth weight. This study also found that risk factors for premature births and low birth weight were similar in both singleton and multiple births. Gestational age was confirmed to be the single most important risk factor for low birth weight. The findings of this study suggest that in order to reduce the incidence of low birth weight and premature births, health improvement strategies should focus on anti-smoking campaigns during pregnancy and other healthcare programmes targeted at the socially disadvantaged populations identified in the study.

Portopulmonary hypertension in decompensated cirrhosis with refractory ascites.

BACKGROUND: The prevalence of portopulmonary hypertension (PPHTN) in patients with cirrhosis and refractory ascites is unknown. Its presence may preclude patients from receiving a transjugular intrahepatic portosystemic shunt or liver transplantation as a definitive treatment for their end stage cirrhosis. PURPOSE: To determine the prevalence, possible aetiological factors, and predictive factors for the development of PPHTN in these patients. METHODS: Sixty two patients (53 males, nine females; mean age 54.5 (1.4) years) with biopsy proven cirrhosis and refractory ascites underwent angiographic measurements of pulmonary and splanchnic haemodynamics. Endothelin 1 levels were measured from the pulmonary artery. Forty nine patients underwent radionuclide angiography for measurements of central blood volume, pulmonary vascular, and cardiac chamber volumes. Forty seven patients also underwent two dimensional echocardiography for measurements of cardiac structural and functional parameters. Cardiac output, and systemic and pulmonary vascular resistance were calculated. RESULTS: Ten patients (16.1%) fulfilled the criteria for PPHTN (mean pulmonary artery pressure >/= 25 mm Hg and pulmonary vascular resistance >/= 120 dynxs/cm(5)), with significantly higher mean right atrial (15.4 (1.2) v 7.9 (0.5) mm Hg; p<0.001), and right ventricular pressures (24.7 (1.5) v 14.7 (0.6) mm Hg; p<0.001), and endothelin 1 levels (3.04 (0.40) v 1.98 (0.12) pg/ml; p=0.02). No significant differences in any of the other parameters measured were detected between the two groups. A right atrial pressure of >/= 14 mm Hg had a 83% positive predictive value for the presence of PPHTN. CONCLUSIONS: Portopulmonary hypertension is common in cirrhosis with refractory ascites, possibly due to excess endothelin 1 in the pulmonary circulation. An elevated right atrial pressure >/= 14 mm Hg predicts the presence of PPHTN, which may be helpful in deciding management options in these patients.

Prophylaxis of radiation-associated mucositis in conventionally treated patients with head and neck cancer: a double-blind, phase III, randomized, controlled trial evaluating the clinical efficacy of an antimicrobial lozenge using a validated mucositis scoring system.

PURPOSE: Mucositis occurs in almost all patients treated with radiotherapy for head and neck cancer. The aim of this multicenter, double-blind, prospective, randomized trial was to evaluate the clinical efficacy of an economically viable antimicrobial lozenge (bacitracin, clotrimazole, and gentamicin [BcoG]) in the alleviation of radiation-induced mucositis in patients with head and neck cancer. PATIENTS AND METHODS: One hundred thirty-seven eligible patients were randomized to treatment with either antimicrobial lozenge (69 patients) or placebo lozenge (68 patients). The primary end point of the study was the time to development of severe mucositis from the start of radiotherapy. Secondary end points included severity and duration of mucositis, pain measurement, radiation therapy interruption, and quality of life. Mucositis was scored using a validated mucositis scoring system. RESULTS: Toxicity profiles were similar between the two arms of the study. The median time to development of severe mucositis from the start of radiotherapy was 3.61 weeks on BCoG and 3.96 weeks on placebo (P =.61). There were no statistically significant differences between the arms in the extent of severe mucositis as measured by physician, in oral toxicities as recorded by patients, or in radiotherapy delays. CONCLUSION: This study was conducted on the basis of a pilot study that demonstrated the BCoG lozenge to be tolerable and microbiologically efficacious. A validated mucositis scoring system was used. However, in this group of patients treated with conventional radiotherapy, the lozenge did not impact significantly on the severity of mucositis. Whether such a lozenge would be beneficial in treatment situations where rate of severe mucositis is higher (ie, in patients treated with unconventional fractionation or with concomitant chemotherapy) is unknown.

Absence of a pharmacokinetic interaction between digoxin and levofloxacin.

BACKGROUND: Levofloxacin, a broad-spectrum fluoroquinolone, may enhance digoxin bioavailability by eliminating intestinal flora that metabolize digoxin. Moreover, levofloxacin, which is eliminated primarily by glomerular filtration and active tubular secretion, may alter the elimination rate of digoxin. Because of the narrow therapeutic index of digoxin, it is important to evaluate the potential for interaction with levofloxacin when administered concomitantly. METHODS: This was a placebo-controlled, randomized, double-blind, two-phase crossover study. Twelve healthy subjects (six males and six females) received 500 mg twice/day oral doses of levofloxacin or placebo for 6 days and a single oral dose of 0.4 mg digoxin on the morning of study day 5 along with levofloxacin or placebo. RESULTS: There was no significant effect of levofloxacin on the pharmacokinetics (Cmax, AUC, and other disposition parameters) of oral digoxin. Steady-state levofloxacin absorption and disposition kinetics were also similar in the presence or absence of digoxin. CONCLUSIONS: Results of this study suggest that an important pharmacokinetic interaction between levofloxacin and digoxin is unlikely to occur when administered concomitantly.

Penetration of levofloxacin into skin tissue after oral administration of multiple 750 mg once-daily doses.

OBJECTIVE: To probe the pharmacokinetic basis for the use of levofloxacin for complicated skin and skin-structure infections (SSSIs) at a once-daily dosage of 750 mg by investigating its penetration into skin tissue. METHOD: Ten healthy volunteers were administered three oral, once-daily 750 mg doses of levofloxacin, and levofloxacin concentrations were subsequently measured over time (0.5-24 h) in skin-punch biopsy tissue and plasma. RESULTS: Skin tissue concentrations consistently exceeded those in plasma at every time point, with tissue/plasma ratios of 1.37 +/- 0.81 for peak concentration and 1.97 +/- 0.35 for area under the concentration versus time curve. Three of the ten subjects reported treatment-emergent adverse events (AEs) that were considered unrelated to treatment. An 11th subject who had enrolled in the study withdrew after AEs of mild severity that were possibly related to the study drug. CONCLUSION: The results support the clinical usage of levofloxacin 750 mg once-daily for complicated SSSIs.

Transcript levels of the eukaryotic translation initiation factor 5A gene peak at early G(1) phase of the cell cycle in the dinoflagellate Crypthecodinium cohnii.

A cDNA encoding a eukaryotic translation initiation factor 5A (eIF-5A) homolog in heterotrophic dinoflagellate Crypthecodinium cohnii (CceIF-5A) was isolated through random sequencing of a cDNA library. The predicted amino acid sequence possesses the 12 strictly conserved amino acids around lysine 52 (equivalent to lysine 50 or 51 in other eukaryotes). A single 1.2-kb band was detected in Northern blot analysis. In synchronized C. cohnii cells, the transcript level peaked at early G(1) and decreased dramatically on the entry to S phase. Although this has not been previously reported, studies of budding yeast (Saccharomyces cerevisiae) and certain mammalian cell types suggest a role for eIF-5A in the G(1)/S transition of the eukaryotic cell cycle. Phylogenetic trees constructed with 26 other published eIF-5A sequences suggest that CceIF-5A, while falling within the eukaryotic branches, forms a lineage separate from those of the plants, animals, and archaebacteria. The posttranslational modification of eIF-5A by a transfer of a 4-aminobutyl moiety from spermidine to conserved lysine 50 or 51, forming amino acid hypusine, is the only demonstrated specific function of polyamines in cell proliferation. It has been suggested that polyamines stimulate population growth of bloom-forming dinoflagellates in the sea. We demonstrate here putrescine-stimulated cell proliferation. Furthermore, ornithine decarboxylase inhibitor D-difluoromethylornithine and the specific hypusination inhibitor N-guanyl-1,7-diaminoheptane exhibited inhibitory effects in two species of dinoflagellates. The possible links of polyamines and saxitoxin synthesis to the arginine cycle are also discussed.

Paclitaxel and carboplatin, alone or with irradiation, in advanced or recurrent endometrial cancer: a phase II study.

PURPOSE: To evaluate the efficacy of carboplatin plus paclitaxel in primarily advanced or recurrent endometrial cancers. PATIENTS AND METHODS: Four distinct patient groups received carboplatin (area under the curve, 5 to 7) plus paclitaxel 175 mg/m(2) for 3 hours at 4-week intervals: group 1 (n = 21), patients with primarily advanced, nonpapillary serous cancers; group 2 (n = 20), the same as group 1 but with papillary serous cancers; group 3 (n = 18), recurrent, nonpapillary serous cancers; and group 4 (n = 4), recurrent, papillary serous cancers. Involved-field irradiation was used in groups 1 and 2 for those with radioencompassable disease. RESULTS: Sixty-three patients were treated. Response rates to chemotherapy in the assessable patients in the four groups were 78% (95% confidence interval [CI], 51% to 100%); 60% (95% CI, 35% to 85%), 56% (95% CI, 34% to 78%), and 50%, respectively. Nineteen patients (90%) in group 1 also were irradiated, and the median failure-free survival time for all 21 patients was 23 months, with a 62% 3-year overall survival rate. Eleven patients (55%) in group 2 were irradiated, and the median failure-free survival time for all 18 patients was 18 months, with a 39% 3-year overall survival rate. The median failure-free interval in the patients in group 3 was 6 months, with a 15-month median overall survival time. Toxicity was manageable, reversible, and predominantly hematologic. Two patients developed neutropenic fever, and three patients, including these two, were hospitalized for complications. CONCLUSION: Carboplatin-paclitaxel is an efficacious, low-toxicity regimen for managing primarily advanced or recurrent endometrial cancers.

Early stage uterine papillary serous carcinoma of the endometrium: effect of adjuvant whole abdominal radiotherapy and pathologic parameters on outcome.

BACKGROUND: Uterine papillary serous carcinoma (UPSC) is an aggressive subtype of endometrial cancer, behaving like ovarian epithelial cancers and having a predilection for transperitoneal relapse. Within this subtype of uterine cancers, predictors of outcome and the role of adjuvant therapies have not been firmly established, to the authors' knowledge. METHODS: Between 1985-1995, 78 patients who had International Federation of Gynecology and Obstetrics (FIGO) Stage I, II, or IIIa UPSC (based on positive washings only) were seen at the British Columbia Cancer Agency. During this time, the authors had a policy of offering adjuvant pelvic, paraaortic and whole-abdominal radiotherapy (WART) to these patients. Fifty-eight patients received adjuvant WART, and 20 received lesser or no adjuvant therapy. The authors undertook a retrospective analysis of pathology with quantification of the percentage of papillary serous component (% PSC) and p53 expression. Pathology was retrieved and reviewed on 62 patients; p53 staining was performed on blocks from the hysterectomy specimen in 46 cases. Pathologic parameters, stage, and adjuvant therapy were correlated with clinical outcome in a multivariate analysis. RESULTS: Median follow-up was 52 months (3-139 mos) and the 5-year disease-specific survival rate was 66.2%. The 58 patients who received adjuvant WART had a significantly better 5-year disease-specific survival than those 20 patients who did not, 74.9% versus 41.3% (P = 0.04). Multivariate analysis showed that % PSC and p53 were not significant predictors of outcome for early stage UPSC. Of the factors examined, only FIGO stage and WART significantly predicted improved outcome (P = 0.02 and 0.04, respectively). CONCLUSIONS: The current study demonstrated a significant difference in the outcomes of patients who had FIGO Stage I compared with Stage II UPSC. In the current series of patients, the authors were not able to predict outcome based on % PSC or p53 expression. The current study results with WART were promising, and WART merits further study.
