Intravenous treprostinil sodium can provide sustained improvements in exercise capacity and haemodynamics, according to data presented by Vallerie McLaughlin, associate professor of medicine and director of the pulmonary hypertension programme, University of Michigan. In this open-label, multi-centre study, 47 PAH patients were treated with intravenous treprostinil either as initial therapy de novo; n 16 ; or as replacement for epoprostenol transition; n 31 ; . At one year, data were available for 16 patients five de novo and 11 transition ; . In the de novo group, six-minute walk distance increased from 323 35m at baseline to 454 43m at one year mean increase 131m; P 0.06 ; . Distances were unchanged in the transition group 482 18m to 482 12m; P 0.96 ; . The de novo group also experienced significant improvements in mean pulmonary artery pressure 66 9mmHg at baseline to 48 7mmHg at one year; P 0.006 ; , cardiac index 1.5 0.1L min m2 to 2.5 0.2L min m2; P 0.04 ; , and pulmonary vascular resistance 37 5 Wood units.m2 to 16 4 Wood units.m2; P 0.01 ; . Dr McLaughlin concluded that the clinical efficacy of intravenous treprostinil appears to be maintained at one year and that it may be an effective alternative to intravenous epoprostenol in selected PAH patients

Quality of life QOL ; .Simpler regimens may improve adherence and QOL, and thereby help to ensure long-term efficacy, safety, and tolerability. Methods: This 48-week, open-label, randomized, multicenter study compares patients with an undetectable viral load at baseline on a twice daily BID ; or more frequently dosed standard of care SOC ; regimen who were randomized 2: 1 ; to switch to a once daily QD ; regimen of stavudine extended-release, lamivudine, and efavirenz d4T XR + 3TC + EFV ; or continue on their SOC regimen.A 12 week planned interim analysis evaluated patient adherence, satisfaction, preference, and QOL at baseline and Week 12 using the ACTG Adherence Questionnaire, Medication Event Monitoring System MEMS ; caps, Subject Treatment Satisfaction Preference Surveys, the Functional Assessment of HIV Infection FAHI ; , and the Illness Intrusiveness Rating Scale IIRS ; . Results: Of 101 patients randomized, 94 patients 62 on d4T XR + 3TC + EFV, 32 on SOC ; remained in the study after Week 12.Based on the Adherence Questionnaire 79% of the d4T XR + 3TC + EFV and 55% of the SOC patients did not miss any doses of medications over the 4 preceding days and followed medication specific directions at Week 12 p 0.017 ; .MEMS cap data collected through week 12 confirmed that D4T XR + 3TC + EFV patients had better adherence mean 96%, median 99% ; than SOC patients mean 83%, median 95% ; p 0.001 ; . D4T XR + 3TC + EFV patients reported greater treatment satisfaction compared with SOC patients for 6 of the 7 questions on the survey. Most d4T XR + 3TC + EFV patients 93.5% ; preferred this regimen to their previous SOC regimen p 0.001 ; .There were no significant QOL changes for either group based on the FAHI and IIRS. Conclusion: Twelve weeks after switching from a SOC regimen to d4T XR + 3TC + EFV, the majority of patients preferred d4T + 3TC + EFV QD compared to their previous regimen. Individuals on d4T XR + 3TC + EFV exhibited significantly better adherence and treatment satisfaction than those on a BID or more frequently dosed HAART regimen. Data regarding efficacy and safety will be presented at a later date.

Robbins, Ivan M., Leslie L. Cuiper, C. Michael Stein, Alastair J. J. Wood, Huai B. He, Richard Parker, and Brian W. Christman. Angiotensin II mediates systemic rebound hypertension after cessation of prostacyclin infusion in sheep. J. Appl. Physiol. 85 2 ; : 731737, 1998.--Prostacyclin or epoprostenol ; , an arachidonic acid metabolite, is an effective treatment for patients with primary pulmonary hypertension. Interruption of chronic prostacyclin infusion can result in recurrent symptoms of dyspnea and fatigue. The etiology of this phenomenon is unknown. We hypothesized that sympathoadrenal activation could lead to increased vascular tone after abrupt termination of the infusion. To evaluate this effect, we monitored six chronically instrumented, awake sheep during and after infusion of prostacyclin. Prostacyclin decreased mean arterial pressure MAP ; by 14% and increased cardiac output by 33%. After the infusion ceased, MAP rebounded 23% above baseline, and cardiac output decreased by 28% from peak values within 10 min. We were unable to demonstrate an increase in norepinephrine levels after cessation of prostacyclin, nor did -adrenergic blockade affect postinfusion hemodynamics. However, plasma renin activity increased 10-fold at peak infusion and remained elevated for up to 2 after discontinuation of prostacyclin. Coinfusion of the angiotensin II-receptor antagonist L-158, 809 resulted in complete abrogation of the postcessation rise in MAP. We conclude that renin-angiotensin system activation is primarily responsible for systemic hypertension occurring after abrupt cessation of prostacyclin infusion in sheep and that angiotensin II receptor blockade prevents this response. Our data do not support a role for sympathetic nervous system activation in the systemic pressor response after prostacyclin infusion. prostaglandin I2; epoprostenol; pulmonary hypertension; renin; norepinephrine.

Coronary disease. During the study period in which 17 patients were operated, four patients were excluded on the following basis: ejection fractions of 0. 15 less and no left ventricular aneurysm four of four patients ; , critical but inoperable coronary artery disease two of four patients ; , and moderate to severe mitral insufficiency two of four patients ; . Of these four patients, one died from recurrent arrhythmias and one died of amiodarone pulmonary toxicity and recurrent VT. Participation in this clinical investigational protocol required patient consent to serial electrophysiologic studies and gated nuclear ventriculograms preoperatively and at 1 to weeks, at 6 to 12 weeks, and at 1 year postoperatively. Preoperative electrophysiologic studies were performed to establish that the VT was inducible, to establish a preliminary localization of the " site of origin" of VT by endocardial catheter mapping when feasible ; and to evaluate the response to pharmacologic inter~ ventions by serial electrophysiologic study when appropriate. Cardiac catheterization and angiography were performed for assessment of hemodynamic status, and biplane left ventriculography was used to assess ventricular function; coronary arteriography was also performed. Gated nuclear ventriculograms were obtained for serial assessment of wall motion abnormalities and ejection fraction. Telephone contact with each patient was maintained on a and erbitux.
Data remotely for consultation. The remote specialist responded quickly, which the family perceived as helpful while they waited for an appointment with a local specialist. Outcome of telehealth consultation was consistent with the in-person evaluation two months later. The Family in Case #2 opted for telehealth evaluation because it was unclear when a local in-person evaluation could be arranged. The family was delighted to be able to send their child to a new school much sooner than would have otherwise been possible. Conclusion: Families with autism perceived Telehealth as a reliable vehicle for accessing specialty care. In addition, the application of the videophone technology demonstrated the practicality of accessing remote resources during a time of emergency. PS1.33 ASSESSMENT PROTOCOL FOR CLINICAL, NEUROLOGICAL, AND NEUROIMAGING CHARACTERIZATION OF NON-VERBAL AUTISTIC CHILDREN IN VENEZUELA . A PILOT STUDY Joaquin A Pea, Cecilia Montiel-Nava, Enoe Medrano, Isabel Montiel-Barbero, Eduardo Mora-La Cruz, Jos A Chacn, Postgrado de Neurologa Peditrica-La Universidad del Zulia Background: With the advent of standardized diagnostic tools expert clinicians are now able to diagnose autism reliably. Objective: In this study we present preliminary findings of the assessment protocol developed to identify and characterize non-verbal autistic children in Venezuela. Methods: participants of this study were recruited thru advertisement in local newspapers. The inclusion criteria was having a diagnosis of Autistic Syndrome according to the ADOS-G, receptive language lower than 36 months according to the VABS. Children with another medical condition were excluded. Written informed consent was obtained from all parents or guardians of the subjects. Each patient was assessed using: the VABS, a Developmental History, ADOS-G, Neurological Examination, karyotyping and screening of X-Fragile EEG , SPECT brain perfusion imaging with Tc-99m ECD, and H-MRS. Results: Of the 33 children, 8 had receptive language abilities above 36 months; and 4 had an additional medical condition ataxia, seizures, hemiparesis, and heart disease ; , causing them to be excluded. Patients exhibited less perfusion in the left brain hemisphere in all of the ROI. These findings represent a decrease in the values of brain perfusion and confirm the existence of a dysfunction in the areas related to language, which leads to an anomalous hemispheric specialization in non-verbal autistic children Conclusion By following a standardized assessment protocol the identification of ASD in our research facility is more accurate. Furthermore, data obtain through physical, neurological, neuroimaging and genetic information for each case will lead to a better understanding of the comorbid features of ASD.

This study showed a trend but no statistical significance towards haemodynamics or clinical improvement due to the combination of bosentan and epoprostenol therapy in patients with pulmonary arterial hypertension and ergotamine.
The results presented in this study showed a significant reduction of neointimal hyperplasia and hence restenosis after experimental implantation of Palmaz-Schatz stents coated with a PLA polymer, releasing r-PEG hirudin and iloprost. The histopathological examination revealed no apparent inflammatory reaction after 28 days. Considering the failure of oral pharmacological treatments to reduce restenosis after interventional stent implantation in humans, the method of local drug delivery deserves further attention

Why the disparity? The EUROCARE results showed that in some countries cancer patients stand a better chance of survival than in others. The reasons will vary from cancer to cancer. In colorectal cancers, good quality surgery is known to be critical in avoiding recurrences. In breast cancer, expert surgery, radiotherapy and appropriate drugs all play a role. Catching the cancer early and getting the diagnostic work-up right are enormously important. Evidence showing the relative contribution made by each factor on survival rates would be very helpful for policy makers deciding where to concentrate their resources

SPECIAL SECTION: predominantly accumulated in mucosa of colon, stomach and bladder, with little in the submucosa and smooth muscle layers. Subsequent light treatment resulted in mucosal ablation only. Three patients were administered oral ALA, and biopsy samples demonstrated preferential PpIX accumulation after 46 h. Following topical application only in normal skin after 4 h, a 12 interval was required in order for tumor cells situated in lower dermis to become maximally fluorescent19. At 308 nm, the optimal performance of the excimer laser is 30 mJ pulse at one-half peak power for 10.9 ns. Generation of the 630 nm high energy beam used in PDT requires coupling the excimer laser to a system containing 2 molar Rhodamine B dye in ethanol23. Recently, a new high-power red laser diode and system Panasonic, Osaka, Japan ; was developed for PDT. This system has a wavelength of 664 nm and a power output of 500 mW cm2 CW ; in tissue. Diode laser has considerable potential for PDT involving current sensitizers, especially Npe6. Furthermore, this system is compact 49 20 40 light weight 20 kg ; , easy to operate and only needs 100 VAC 3 A power supply with no maintenance.

The 2 women who reported scalp pruritus for pruritus complete blood cell count, liver function tests, and measurement of levels of blood urea nitrogen, creatinine, glucose, and thyroid stimulating hormone ; . A psychiatric cause or overlay has been reported in patients with chronic pain syndromes or cutaneous dysesthesias.1, 2, 9-12 In fact, chronic pain has been referred to as a "depressive equivalent."9 Many of the chronic pain syndromes were initially thought to represent a psychiatric disorder only. However, one must be cautious when reviewing data describing a personality profile or a psychiatric disorder associated with any chronic condition, particularly a painful one.3, 13 Is a psychiatric disturbance ie, depression ; the cause of chronic pain or does experiencing chronic pain result in symptoms of depression? A subset of chronic pain sufferers probably do have an underlying psychiatric illness causing their symptoms. However, in the experience of Bowers, 13 "most of the cutaneous mucosal pain syndromes are notcaused into the chronic pain syndromes now suggests that they may represent a neurologic dysfunction that in some cases is associated with a secondary psychiatric component. It is interesting that 5 of our patients had 1 or more physician-diagnosed psychiatric disorders. Dysthymic dis and epoprostenol.
