Abstract
Background From 2000 to today, the use of information technology in the medical field is increasingly widespread, reaching a new milestone following the COVID 19 syndemia. It is increasingly evident that wireless monitoring allows patients to be followed more easily, detecting complications early at home and allowing to limit the contagion of healthcare personnel by reducing the interaction with patients in hospital rooms Methods A pilot Multicenter Open-label Randomized Controlled Trial (RCT) was performing comparing wearable wireless vital parameters continuous monitoring (WVPCM) system and regular monitoring. Data were collected to provide a clinical-economic impact (costs, program effectiveness and QALY gains) of complex patients (CPs) discharged from Internal Medicine Units. Cost were estimated by mean of the identification, measuring and valorisation of the resources uptake. Results 143 patients (37 M/38 F, mean age: 78.7 years). Major complications: respiratory failure detection (6,5 vs 3,8); reduction of sudden deaths (9.3% vs 16% experimental); care-related infections (6,5 vs 7,5), glycemic decompensation (4,3 vs 1,9). Hospital readmission within 21 days were 7% vs 11%. Relevant cost driver was time spent by nurses: 58 minutes/day/patient (vs 132) allow to save €54-90/patient. One way and multiway sensitivity analyses confirmed the robustness of our results with nearly 99% of the replications involved Conclusions WVPCM, detecting early complication during the post-discharge CPs monitoring, may facilitate a timely response ensuring a more appropriate management of complex patients seen (>25% of total admissions), reduce the time to diagnosis, improve efficiency/efficacy of disease management and reduce unnecessary clinic visits and hospital (re)admissions. The miniaturized technologies can improve patient adherence and assure better quality of life. WVPCM allows patients to be sent home safely and to effectively integrate Hospital and Community services. Key messages Wearable wireless vital parameters continuous monitoring (WVPCM) system reduce time and cost of nursing. Wearable wireless vital parameters continuous monitoring (WVPCM) system can detect early complication improve patient adherence and assure better quality of life.

Nutritional strategies for psoriasis: current scientific evidence in clinical trials. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2019; 22:8537-8551. [PMID: 30556896 DOI: 10.26355/eurrev_201812_16554] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Indexed: 11/12/2022]
Abstract
OBJECTIVE Several nutritional strategies for the management of psoriasis are promising. Even if recent data support that nutrition may play a pivotal role in prevention and co-treatment and despite patient's concerns regarding the best nutritional habits, the consensus regarding the nutritional strategies to be adopted lacks in clinical settings. In this manuscript, the effects of several nutritional strategies for psoriasis patients such as hypocaloric diet, vitamin D, fish oil, selenium, and zinc supplementation were systematically reviewed. Randomized controlled trials (RCTs) on beneficial botanical oral supplements were also included in the analysis. MATERIALS AND METHODS For each topic, a search was conducted in MEDLINE electronic databases for articles published in English between January 1, 1990 and September 2018. Two independent reviewers assessed and extracted the data. Only controlled clinical trials were selected. RESULTS The evidence regarding the current nutritional strategies for psoriasis patients were summarized and translated into a global, comprehensible recommendation. CONCLUSIONS Weight loss combined with a healthy lifestyle was shown to be very beneficial for patients with moderate to severe disease with a significant reduction of the Psoriasis Area and Severity Index (PASI) score. Currently, oral vitamin D supplementation for prevention or treatment of psoriasis in adults with normal vitamin D levels is not recommended; however, psoriasis patients with a deficit in plasma vitamin D levels are advised to complement with oral supplements to prevent psoriasis-related comorbidities. Instead of zinc, selenium, and omega 3 supplements have been proven beneficial for psoriasis patients. Among botanical species, Dunaliella bardawil (D. bardawil), Tripterygium wilfordii (T. wilfordii), Azadirachta indica (A. indica), Curcuma longa (C. longa), and HESA-A are the most beneficial. In conclusion, a close cooperation between nutritionists and dermatologists may be useful for the management of psoriasis.

Influence of the Mediterranean diet on carotid intima-media thickness in hypercholesterolaemic children: a 12-month intervention study. Nutr Metab Cardiovasc Dis 2014; 24:75-82. [PMID: 23809150 DOI: 10.1016/j.numecd.2013.04.005] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2012] [Revised: 04/11/2013] [Accepted: 04/16/2013] [Indexed: 11/28/2022]
Abstract
BACKGROUND AND AIMS The Mediterranean diet has been recognised as having a protective role on the cardiovascular system due to its low lipid and high antioxidant content. Lipid profile and oxidant status represent two important risk factors related to endothelial dysfunction, even at early stages of cardiovascular diseases. The aim of the study was to evaluate the influence of a 12-month Mediterranean diet on the variation of lipid profile and carotid intima-media thickness (cIMT) in pre-pubertal hypercholesterolaemic children. METHODS AND RESULTS We performed a cross-sectional study comparing lipid profile and cIMT in a group of 68 pre-pubertal children (36 with hypercholesterolaemia and 32 controls). In addition, in the hypercholesterolaemic children a 12-month intervention programme with a Mediterranean diet was started to evaluate the variation of lipid profile and cIMT. At baseline, hypercholesterolaemic children showed a significantly higher cIMT (both right and left carotid artery) compared to controls (both p < 0.05). After 12 months of diet intervention, a significant reduction of total cholesterol, LDL-cholesterol and cIMT was documented (all p < 0.05). Furthermore, at the end of follow-up, delta body mass index-Standard Deviation score and delta LDL-cholesterol were significantly and independently related to the changes of cIMT (both p < 0.05). CONCLUSION The Mediterranean diet represents a valid approach in the treatment of hypercholesterolaemia even during childhood.

Abstract
BACKGROUND The aim of this paper was to determine if there were any significant differences between the effects of fentanyl delivered as a bolus or remifentanil delivered as a continuous infusion on the QT interval and QT dispersion (QTD) during the induction of anesthesia and tracheal intubation. METHODS This was a prospective, randomized and single blind study. A total of 50 ASA I-II patients scheduled to undergo elective minor abdominal surgery were divided into two groups. In the remifentanil group (N=25), patients received a continuous infusion (c.i.) of remifentanil (0.25 mcg/kg · min). In the fentanyl group (N=25), a bolus dose of fentanyl (2.0 mcg/kg) was administered. The QT interval, the difference between QTmax and QTmin (QTD), the heart rate-corrected QT (QTc) and the QT dispersion (QTcD) were calculated using a 12-lead computerized electrocardiogram (ECG). RESULTS In both groups, there was no significant change in QT or QTc intervals during the study period. In the remifentanil group, a significant decrease in QTD and QTcD was observed during induction compared with baseline values (P<0.05). There was a significant increase in QTD at 1 min and in QTcD at 1 and 3 min after intubation in the fentanyl group (P<0.05). CONCLUSION Both remifentanil and fentanyl did not prolong the QT interval. QTD decreased after the induction of anesthesia and did not increase after tracheal intubation in patients receiving c.i. remifentanil in comparison with fentanyl. Overall, remifentanil infusion may be the opioid-based treatment regimen of choice in patients at risk of dysrhythmias.

Abstract
BACKGROUND The aim of the study was to evaluate the effects of pneumoperitoneum and head-up position on autonomic cardiac function changes during inhalational or total intravenous anesthesia by using the analysis of QT dispersion and heart rate variability (HRV). METHODS In this prospective, single-blind study, 30 patients scheduled for elective laparoscopic cholecystectomy were randomly divided in two groups: a sevoflurane-based inhalational anesthesia group (N=15) and an intravenous anesthesia group with propofol (N=15). Propofol 2.0 mg/kg-1 and cisatracurium 0.15 mg/kg-1 during induction of anesthesia and Remifentanil as titrated infusion for analgesia were used in both groups. Pneumoperitoneum was established at 12 mmHg with patients in the supine position. ECG was recorded before the induction of anesthesia; 1 and 3 min after pneumoperitoneum (supine position); 1 and 3 min after shifting the patient to a head-up position (HUP) of 60 degrees; after abdominal deflation; and after awakening. RR interval, QT interval, corrected QT interval (QTc), QT interval dispersion (QTD), corrected QT interval dispersion (QTcD), low-frequency power (LF), high-frequency power (HF) and LF/HF ratio were recorded. RESULTS The LF/HF ratio increased significantly after 3 min HUP in the SEVO group (P<0.05). QTD and QTcD increased significantly at 3 min after abdominal insufflation and at 1 and 3 min after HUP in both groups (P<0.05). CONCLUSION Statistically significant increases of QTD and QTcD occurred during pneumoperitoneum and HUP, regardless of the anesthetic techniques used. In patients receiving inhalational anesthesia, the LF/HF ratio increased significantly after HUP.

Abstract
General anesthetics and contrast media can cause anaphylactic as well as anaphylactoid reactions. These events are of great concern to radiologists and anesthesiologists because of their relatively high prevalence, possible threat to life, and medical-legal consequences. Points discussed in this review are the critical evaluation of risk factors affecting prevention strategies, the need to be aware of pathogenic mechanisms relevant to prevention strategies, the use of alternative products if a culprit agent is known, the recognition of early signs of a reaction, the need to keep records of reactions on a patient's medical chart, the planning of prophylactic therapy, recommended actions after a reaction to an anesthetic or contrast medium, and the suggested establishment of allergy-anesthesiology centers to improve cooperation, and medical-legal issues. As any drug or contrast medium administered during general anesthesia or a diagnostic procedure can induce a potentially life-threatening or fatal event even in the absence of any evident risk factor in the patient's medical history or clinical status, we usually premedicate susceptible individuals at least to attenuate the severity of an unpredictable reaction, although we cannot rely on the efficacy of premedication to completely prevent a severe event. These recommendations, which are based on the literature and on the experience of our working group, aim to provide useful information for physicians and other specialists who operate in the absence of an allergy consultant.

Abstract
AIM Maps and nomograms are routinely used to evaluate acid-base equilibrium (ABE), but often require previous skilled practice and time to be used in the clinical setting; moreover, some definite alterations may be missed. The aim of this study was to evaluate the new slide rule (patented by Authors) for the rapid, precise and complete assessment and diagnosis of altered blood gas analysis (ABG) parameters and compare it to traditional methods. METHODS Once pH, bicarbonate and PaCO(2) values are known by arterial blood gas analysis (ABG), the slide rule can calculate, show and instantly diagnose the related alteration, including possible mixed partial compensated ones. In this regard, 330 patients coming from 6 (4 national and 2 foreign) clinics were studied; each patient underwent evaluation of ABG alterations using traditional methods and the slide rule immediately thereafter. RESULTS The results of consecutive evaluations on involved patients made by specialists in all clinics were in agreement; nonetheless, the slide rule was far more user friendly, rapid and complete in the ABE alterations' diagnostic range, in comparison with traditional methods. CONCLUSION All involved specialists confirmed that the new slide rule was able to rapidly diagnose ABE alterations, including mixed or partially compensated ones that may be missed by traditional methods.

Abstract
Heart allograft outcome is unpredictable and acute rejection episodes still occur despite the improvement of immunosuppressive regimens. We therefore investigated whether the immunopathological profile of endomyocardial biopsies might underlie the variations in the clinical course of a graft. Biopsies from transplanted patients were analysed by histology, immunohistochemistry (associated with digital image analysis), confocal and electron microscopy to determine the type and the functional state of leukocytes infiltrating the myocardium, together with their ultrastructural features and those of the graft itself. In comparison with biopsies with grade 0R or grade 1R rejection, those from patients with grade 2R rejection displayed significant infiltration of macrophages, T lymphocytes, and CD83+ and DC-SIGN+ dendritic cells. Fifty-seven per cent were invaded by CD20+B lymphocytes, most of which expressed CD69 activation marker and cooperated in interleukin-12 production, and by CD69+CD94+NK cells expressing interferon-gamma. Ultrastructural signs of myocyte degeneration and microvessel rupture by NK cells were frequent. These patients developed recurrent episodes of acute allograft rejection. Endomyocardial B and NK infiltrates are involved in the dynamics of allograft rejection and are associated with a high risk of its recurrence. Immunopathological assessment of endomyocardial biopsies may thus serve to forecast the probable outcome of a heart allograft.

Abstract
AIM The aim of this study was to evaluate the haemodynamic changes in patients undergoing cytoreductive surgery and intraperitoneal hyperthermic chemotherapy (IPHC) using an echo-Doppler device (Hemosonic 100). METHODS EXPERIMENTAL DESIGN haemodynamic and cardiac function variables during IPHC, using a closed abdomen technique, were measured with the use of a non-invasive esophageal echo-Doppler monitor. SETTING operating room in an oncologic surgery department in hospital. Fifteen patients, ASA II or III with age ranging from 59 to 66 years were successively studied. All patients were under general anaesthesia with sevoflurane, remifentanil as titrated infusion, and cisatracurium for muscle relaxation. The standard monitoring included ECG, capnometry, invasive measurement of blood pressure and central venous pressure, pulsoximetry, diuresis, esophageal and tympanic temperature. Haemodynamic changes evaluated by an echo-Doppler device were recorded at predetermined times. RESULTS A significant reduction in stroke volume (SV) and aortic blood flow (ABF) values was recorded (P<0.05) during the abdominal cavity filling, followed by a significant increase in total systemic vascular resistance values (P<0.05). A significant increase in SV, ABF and left ventricular ejection time was recorded 90 min after the start of IPHC procedure (P<0.05) when the body temperature increased. Peak velocity and acceleration values increased significantly at the same time. CONCLUSIONS These results suggest that the echo-Doppler device (Hemosonic 100) provided an easy-to-handle, non-invasive and reliable tool to monitor changes in cardiac parameters during IPHC.

Abstract
AIM The transition from intraoperative analgesia to postoperative analgesia must be planned carefully after remifentanil-based anesthesia, due to the short duration of action of remifentanil. The aim of this study is to compare the efficacy and safety of 2 transition strategies using sufentanil or tramadol for early postoperative pain relief in patients who had major abdominal surgery under general anesthesia with remifentanil/sevoflurane. METHODS Sixty patients participated in this double-blind, prospective study and were randomly assigned to either sufentanil (S) group or tramadol (T) group. Twenty minutes before the end of surgery the patients received either a bolus of 0.15 microg kg(-1) sufentanil (group S) or tramadol 100 mg (group T). Mean arterial pressure (MAP), heart rate (HR) and rate pressure product (RPP=systolic arterial pressure (SAP)xHR), analgesia by a verbal rating score (VRS) and sedation by a sedation score (SS) were evaluated at emergence from anesthesia. RESULTS A statistically significant difference in HR between the 2 groups was recorded at extubation (78+/-13 in group S vs 86+/-24 in group T). A significant decrease of RPP values at extubation and 5 minutes later were found in group S in comparison with group T. VRS values were significantly lower in sufentanil group at 5 and 10 minutes after awakening. CONCLUSIONS Sufentanil provided more effective transition analgesia in comparison with tramadol. The effects of remifentanil dissipated rapidly and analgesia with major opioids was required. A bolus dose of sufentanil 0.15 microg kg(-1) was efficacious in controlling the hemodynamic parameters at awakening from anesthesia. The lower HR values and, consequently the lower RPP values are of utmost importance especially in the aged cardiovascular risk patient.

Abstract
OBJECTIVES The aim of the study was to assess whether the well-tolerated serotonin re-uptake inhibitor paroxetine hydrochloride could prevent vasovagal syncope in young patients resistant to or intolerant of previous traditional therapies. BACKGROUND Serotonergic mechanisms may play a major role in the pathophysiology of neurocardiogenic syncope, and serotonin re-uptake inhibitors have been recently reported to be effective in preventing episodes. METHODS Forty-one consecutive young patients (13 male and 28 female), aged less than thirty years with recurrent syncope and positive head-up tilt test, and in whom standard therapies with beta-blocking, vagolytic, negative inotropic or mineral corticoid agents were ineffectual, poorly tolerated or contraindicated, randomly received either paroxetine at 20 mg once a day or a placebo. A head-up tilt test was then re-performed after one month of treatment, and the clinical effect was noted over a mean follow-up of 27.1 +/- 6.6 months. RESULTS The response rates (negative tilt test) after one month of treatment were 57.1 versus 33.3% (p < 0.001) in the paroxetine and placebo groups, respectively. During follow-up, spontaneous syncope was observed in 4 patients (19%) in the paroxetine group and in 12 patients (60%) in the placebo group (p < 0.001). Only one patient (4.8%) asked to be discontinued from the drug for severe recurrent headache. CONCLUSIONS Paroxetine significantly improved symptoms of young patients with recurrent vasovagal syncope unresponsive to or intolerant of traditional medications and was well tolerated by patients.

Abstract
BACKGROUND Recurrent syncope represents a debilitating disorder and quality of life deteriorates as a function of recurrence of symptoms. Although the administration of beta-blockers, vasoconstrictors, fludrocortisone, and serotonin reuptake inhibitors may be helpful in preventing episodes, many patients are intolerant of or respond poorly to these agents. Orthostatic training has been reported to be effective in preventing refractory syncope. Thus, to determine whether a tilt training program could prevent symptoms in adolescents, the following controlled study was undertaken. METHODS AND RESULTS Forty-seven consecutive adolescents (18 male and 29 female, mean age 16.0+/-2.2 years) with recurrent syncope and positive head-up tilt test refractory to previous traditional therapies were distributed between 2 groups, depending on their consent (24 patients) or refusal (controls, 23 patients) to enter the program. Orthostatic training was started, in the presence of a family member, with a series of 5 in-hospital sessions. The 24 patients and their relatives were then instructed to perform the tilt training at home by standing against a wall twice a day for a planned duration of up to 40 minutes, depending on the in-hospital orthostatic tolerance. Head-up tilt response was reevaluated after 1 month, and the clinical effect was noted over a mean follow-up of 18. 2+/-5.3 months (range 15 to 23); 26.1% of patients in the control group and 95.8% of patients in the training group became tilt-negative (P<0.0001). Spontaneous syncope was observed in 56.5% versus 0% in the control and training group, respectively (P<0.0001). CONCLUSIONS Orthostatic training was found to significantly improve symptoms of adolescents with neurocardiogenic syncope unresponsive to or intolerant of traditional medications. Twice-a-day training sessions of 40 minutes were well accepted by patients.

Abstract
Head-up tilt test was introduced in clinical practice to assess vasovagal syncope and its use has further been extended to evaluate the efficacy of drug administration in these patients. Nevertheless, the effects of tilt test on vasovagal syncope have never been compared with those obtained by ethylephrine or propranolol administration. One hundred and sixty-nine consecutive patients with vasovagal syncope and positive baseline or nitrate-potentiated tilt test (60 degrees upright position for 45 min, or until syncope occurred; 5 mg sublingual isosorbide dinitrate administration if no symptoms occurred) were randomly distributed among three groups: Group A (57 control patients discharged without medical therapy); Group B (56 patients discharged with 75 mg/die ethylephrine); Group C (56 patients discharged with 80 mg/die propranolol). Tilt test was repeated after 1 month, while clinical outcome was evaluated monthly for a mean follow-up of 37.1 +/- 15.6 months. No significant differences in acute tilt-induced syncope recurrence rates were obtained among groups at test repetition since 70.2% of Group A, 69.6% of Group B and 62.5% of Group C experienced syncope. At 3-year follow-up 82.4% of Group A, 83.9% of Group B and 87.5% of Group C (NS among groups) remained symptom free, the most important clinical result being obtained in untreated patients. These data suggest that tilt test execution may prevent syncope recurrence as ethylephrine or propranolol administration. Irrespective of the therapeutical choice, the "controlled reproduction" of symptoms and some psychophysical training of patients to avoid precipitating circumstances, to recognize early symptoms promptly to be reverted by Trendelemburg position, may produce the same clinical improvement as (empiric) ethylephrine or propranolol therapy.

Abstract
The availability of sensitive methods for detecting and localising the feline immunodeficiency virus (FIV) may help shed light on its role in generating tissue damage observed during infection. As immunohistochemical and in situ hybridisation techniques might not be sufficiently sensitive for this type of study, we adapted to FIV PCR-in situ hybridisation (PCR-ISH) that combine the extreme sensitivity of PCR with the precise localisation provided by ISH. The steps important for the success of PCR-ISH, such as sample preparation, permeabilisation, amplification profile, type of labels, and hybridisation conditions were optimised using paraformaldehyde-fixed and formalin-fixed paraffin-embedded sections of cells infected in vitro with FIV. As controls for amplification, the feline tumor necrosis factor-alpha gene (TNF-alpha) and the non-related EBNA-1 gene of the human Epstein-Barr virus were used. Once the method proved sufficiently sensitive and specific with these cells, the PCR-ISH assay was applied to paraffin sections of the lymph nodes, spleen and central nervous system of a 2-year FIV infected cat that, at the time of challenge, harboured low copy numbers of proviral genomes. Comparison of the results of PCR-ISH, competitive PCR and immunohistochemical analysis are described.

Abstract
Neuropathological changes have been described associated with feline immunodeficiency virus (FIV) infection. The objective of our study was to characterize the lesions found in the brain and spinal cord of experimentally FIV-infected cats and to quantify, by morphometric analysis, the intensity of gliosis found in these subjects at different time post infection (pi). The brains and spinal cords appeared grossly normal. Gray matter of cortical and subcortical structures showed a moderate to pronounced gliosis particularly in all cerebral cortex and hippocampus. Morphometric analysis demonstrated that GFAP immunoreactivity was markedly higher in infected animals. Gliosis was present 15 days pi and did not appear to progress during the infection, whereas neuronal changes when present were observed only in long-term infected animals (15-23 months pi). In a large proportion of infected cats a diffuse gliosis of white matter and vacuolar myelinopathy was also present. Despite some discrepancies observed between neuropathological changes in FIV-infected animals and HIV-infected individuals, the presence in the cerebral cortex of cats with FIV infection of alterations similar to those observed in AIDS patients demonstrates that FIV is an interesting animal model particularly that may be useful for clarifying the pathogenesis of neuropathological changes associated with HIV infection.

Abstract
The mechanism of Fe-induced peroxidation of arachidonic acid (AA) in small unilamellar vesicles (SUV) of dipalmitoylphosphatidylcholine (DPPC) and dipalmitoylphosphatidylethanolamine (DPPE) was studied below and above gel to liquid-crystalline phase transition temperature (Tm). In both liposomes the AA peroxidation resulted higher in the temperature range below Tm, but the extent of malonyldialdehyde (MDA) formation was dramatically lower in DPPE vesicles when compared with corresponding DPPC liposomes. A possible explanation for this is discussed.

Abstract
Posteroinferior infarction often complicated by the contemporaneous antero-septal necrosis due to anterior descending coronary artery critical stenosis. To confirm the value of VCG in the diagnosis of these two necrosis as regards ECG, the Authors have studied with echocardiogram, 19 patients with postero infarction, with or without inferior necrosis. The results were: frequent association of antero-septal infarction in postero-inferior necrosis; morphological and chronological VCG criteria in the diagnosis of postero-septal infarct; VCG use as bloodless method, to distinguish among the subjects with postero necrosis, the patients who must be subjected coronary angiography.

Abstract
Prophylactic antibiotics are prescribed frequently at pacemaker placements despite a paucity of data indicating effectiveness. Battery pack replacement procedures usually are not followed by infections and prophylactic antibiotics in this setting are controversial. Pacing wire and battery pack placement have higher infection rate (about 5%), thus antibiotics may be useful in the prevention of serious infections. In this study three different schemes of antibiotics prophylaxis (local prophylaxis, Short term prophylaxis, conventional postoperative prophylaxis) were compared in 72 patients receiving permanent transvenous cardiac pacemakers. No significant differences were found among these three groups also if S.T.P. showed a greatest simplicity.

Abstract
Data relating to 9 years of definitive electrostimulation in the Abruzzo region are presented. An account is given of the epidemiology, the indications for implantation, the stimulation and control technology, and the complications. It is pointed out that the implantability index rose from 1976 to 1978 to reach values of 130.5 implants/mil/inhab. This is in comparable with that in the literature. The technologies and modalities are rapidly developing, and a definitive picture cannot be drawn as yet. Further cognitive investigations are envisaged.

Abstract
Personal observations of 22 patients with permanent inhibited ventricular PM for SSS during the period July 1976-February 1979 and re-examined with electrophysiological study after a follow-up made for an average period 25,5 months (14 to 49 months), after PM inhibition from the outside are presented. Patients were divided into 2 groups (group 1 with bradycardia and group 2 with brady-tachy arrhythmia). In spite of relative exiguity and uniformity of this casuistry, the conclusion is drawn that CSNRT and atropine test were more significant than SACT, in particular in forms with less pathological electrophysiological parameters.

Abstract
The Authors, after illustrating the pharmacological and physiological characteristics of CT 1341 (Althesin Glaxo), have experimented this medicine in medico-piloted delivery under narcosis on two homogenous groups of 20 patients each. The Authors have evidenced the lack of any harmful effect on the proceeding of labour, the viability of the infant, the delivery of the placenta and on post-partum, provided that a time of induction not too premature with regard to the evolution of labour be respected.
