Abstract
OBJECTIVE To identify the latest advances in suction devices and evaluate their effect in Retrograde intrarenal surgery (RIRS) and ureteroscopy for stones. BASIC PROCEDURES A systematic literature search was performed on 4th January 2023 using Scopus, PubMed, and EMBASE. Only English papers were included; both pediatric and adult studies were accepted. Duplicate studies, case reports, letters to the editor, and meeting abstracts were excluded. MAIN FINDINGS Twenty-one papers were selected. Several methods have been proposed for suction use in RIRS, such as through the ureteral access sheath or directly to the scope. Artificial intelligence can also regulate this system, monitoring pressure and perfusion flow values. All the proposed techniques showed satisfactory perioperative results for operative time, stone-free rate (SFR), and residual fragments. Moreover, the reduction of intrarenal pressure (induced by aspiration) was also associated with a lower infection rate. Even the studies that considered kidney stones with a diameter of 20 mm or higher reported higher SFR and reduced postoperative complications. However, the lack of well-defined settings for suction pressure and fluid flow prevents the standardization of the procedure. CONCLUSION Aspiration device in the surgical treatment of urinary stones favours a higher SFR, reducing infectious complications, as supported by the included studies. RIRS with a suction system provided to be a natural successor to the traditional technique, regulating intrarenal pressure and aspirating fine dust.

Abstract
OBJECTIVE This retrospective study aimed at ascertaining the clinical usefulness of nebulized myo-inositol in the management of patients affected by bronchiectasis. PATIENTS AND METHODS 19 patients, aged between 63 and 73 years old, with bronchiectasis, were treated for 15 days with nebulized myo-inositol or placebo. Lung functionality [forced expiratory volume in the 1st second (FEV1)], solid content of expectorate, and surfactant tension were analyzed. RESULTS All patients treated with nebulized myo-inositol had a significant decrease in the percentage of solid content in the expectorate (T0 7.9±2.8% vs. T1 5.2±2.7%; p<0.001) and surfactant tension (T0 81.5±6.9 mN/m vs. T1 77.4±7.2 mN/m; p<0.001). Among treated patients, these variations correlated with FEV1 (rs=- 0.79; p<0.01) and forced expiratory flow at 25-75% of FVC (FEF25-75%) (rs=-0.81; p<0.01) scores. Also, variation of surfactant tension correlated with FEV1 (rs= -0.74; p<0.05) score. CONCLUSIONS Nebulized myo-inositol increases lung functionality and mucus clearance in patients affected by bronchiectasis.

Abstract
OBJECTIVE The human papilloma virus (HPV) is the etiological agent of cervical cancer in more than 95% of cases worldwide. Although most HPV infections clear up on their own and most pre-cancerous lesions spontaneously resolve, in some cases, they can persist, leading to lesions which may progress towards invasive cervical cancer. MATERIALS AND METHODS We evaluated the effects of the association of epigallocatechin gallate (EGCG) + folic acid (FA) + vitamin B12 (B12) + hyaluronic acid (HA) on HPV-positive cervical cancer cells (HeLa). RESULTS The association of EGCG + FA + B12 + HA induced a significant increase of apoptosis and p53 gene expression with a concomitant decrease of E6/E7 gene expression, a marker of HPV infection. CONCLUSIONS This study provides for the first-time evidence on the potential additive activity of EGCG + FA + B12 + HA in counteracting HPV infection, by increasing apoptosis and p53 expression in HPV-infected cervical HeLa cells.

Abstract
OBJECTIVE The aim of our study was to test if oral high hyaluronic acid (HMW-HA) administration was effective in contrasting induced preterm birth (PTB) in female Wistar rats. MATERIALS AND METHODS A total of 24 pregnant rats were pretreated with placebo or low (2.5 mg/day)/high dose (5 mg/day) of HMW-HA (day 15) and then induced to delivery with mifepristone plus prostaglandin E2 (PGE2) (3 mg/100 µL + 0.5 mg/animal) on the 19th day of pregnancy. The delivery time was recorded and the messenger RNA (mRNA) levels of pro-inflammatory cytokines [tumor necrosis factor-α (TNF-α), interleukin (IL)1β, IL-6] were detected in the uterine tissues by real-time polymerase chain reaction (real PCR). Immunohistochemistry was performed alongside. RESULTS Oral HMW-HA was well absorbed in the body and was able to significantly delay the timing of delivery and decrease mRNA synthesis of pro-inflammatory cytokines. CONCLUSIONS HMW-HA, by acting in the management of PTB, may represent a new approach to protecting physiological pregnancy.

Abstract
This paper presents, for the first time, a method for the rapid quantification of β-carotene in olive oil by Raman spectroscopy. Using a 532 nm Raman laser source, our procedure requires only one drop (100 µL) of oil, for β-carotene content to be determined. Results show that β-carotene content is associated with the lutein/β-carotene ratio, a parameter whose value describes how healthy the olives were before processing, specifically whether an olive fly attack occurred. Since olive fly attacks are not always visible to the oil producers, this method gives them the means to control the validity of the prevention strategies they adopted.

Abstract
OBJECTIVE Oral treatment with inositol hexaphosphate (InsP6) has shown to be efficient in decreasing adverse effects in patients with breast cancer under chemotherapy. This study was aimed at evaluating and comparing the efficacy of topical InsP6 in improving quality of life in women treated with anticancer drugs. PATIENTS AND METHODS The study was a double-blind, randomized controlled trial (RCT) with allocation concealment of 20 patients in two groups, one (experimental) applied 4% topical formulation of InsP6 once a day, whereas the second one (control) a gel containing hyaluronic acid. InsP6 therapy started 6 weeks after lumpectomy. Blood tests were monitored in both groups and quality of life was assessed using standardized QLQ-C30 and QLQ-BR23. RESULTS Patients who applied InsP6 on the breast significantly improved their quality of life and functional status reducing side effects compared to control group; moreover, after treatment, a significant difference between the two groups was observed in the white blood cells and platelets count values. CONCLUSIONS Topical InsP6 treatment has demonstrated to be effective and safe in preventing and/or mitigating chemotherapy-induced side effects as well as the preserving quality of life in women with ductal breast cancer.

Abstract
BACKGROUND The aim of this study was to compare the safety and efficacy of RIRS in men ≥65 years to those <65 years. MATERIALS AND METHODS Patients who underwent RIRS were prospectively collected from March 2013 to March 2014 in 5 European centers. Perioperative outcomes and complications in elderly men were compared with men <65 years. Univariable and multivariable analyses were performed for factors predicting overall complications. The groups were compared using Mann-Whitney U test. Categorical variables were compared using chi-squared test and the Yates correction or the Fisher's exact test. RESULTS A total of 399 patients with renal stones were included, 308 (77.19%) were aged <65 years, 91 (22.8%) were aged ≥65 years. Elderly patients were more likely to have higher ASA scores (35.7% vs 92.3%; p < 001), Charlson Comorbidity Index (1.8 vs. 5.2, p < 0.001), hyperlipidemia (10.06% vs. 30.76%; p = 0,0005) and coronary heart disease (5.51% vs. 17.58; p = 0.005) compared to younger cohort. Perioperative outcomes (stone free rate, operative time and re-intervention rate) did not show differences between the two groups (p > 0.05). Surgical and medical complication rates were similar between the cohorts (14.28% vs 9.89%; p = 0.38). Multivariate analysis did not identify any predictive factors of complications among the two groups (p > 0.05). CONCLUSIONS In this study, elderly RIRS patients had comparable short term efficacy and perioperative complications to younger patients, despite a higher prevalence of comorbidity. Age itself should not be considered as a risk factor for the development of complications in patients undergoing RIRS for renal stone.

Abstract
The aim of this study is to evaluate if surgical experience could influence the outcomes of retrograde intrarenal surgery (RIRS) in terms of stone clearance and complication rate. Patients from five institutions were included in this study. Patients were divided into two groups. Group 1: patients treated by three surgeons in the early phase of learning curve (surgical experience <100 procedures); Group 2: cases operated by two surgeons with great endourological experience (>400 procedures). Patients and stone characteristics, outcome and complications were analyzed. Multivariable regression model was used. Differences between groups were estimated using propensity scores to adjust for the bias inherent to the different characteristics. 381 RIRS were analyzed (Group 1: 150 RIRS; Group 2: 231 RIRS). Clinical data and stone parameters were comparable. The SFR was 70 % in Group 1 and 77.9 % in Group 2 (p = 0.082). Operative time was significantly shorter in the Group 2 (76.3 vs. 53.1 min, p = 0.001). The overall complication rate was significantly lower in Group 2 (20.7 vs. 8.7, p = 0.001). At unadjusted analysis, a non-significant difference was found between centers on SFR (OR 1.51 95 % CI 0.95-2.41). Conversely, a significant difference was found on overall complications (OR 0.36 95 %CI 0.20-0.67) with lower overall complication in Group 2. This study shows that surgeon experience influences the outcomes of RIRS mainly in terms of safety. Further studies will be needed to assess the exact number of procedures necessary to obtain a plateau in the rate of complications and success.

Abstract
Plants lack the adaptive immunity mechanisms of jawed vertebrates, so they rely on innate immune responses to defense themselves from pathogens. The plant immune system perceives the presence of pathogens by recognition of molecules known as pathogen-associated molecular patterns (PAMPs). PAMPs have several common characteristics, including highly conserved structures, essential for the microorganism but absent in host organisms. Plants can specifically recognize PAMPs using a large set of receptors and can respond with appropriate defenses by activating a multicomponent and multilayered response. Lipopolysaccharides (LPSs) and lipooligosaccharides (LOSs) are major components of the cell surface of Gram-negative bacteria with diverse roles in bacterial pathogenesis of animals and plants that include elicitation of host defenses. Little is known on the mechanisms of perception of these molecules by plants and the associated signal transduction pathways that trigger plant immunity.Here we addressed the question whether the defense signaling pathway in Arabidopsis thaliana was triggered by LOS from Xanthomonas campestris pv. campestris (Xcc), using proteomic and transcriptomic approaches. By using affinity capture strategies with immobilized LOS and LC-MS/MS analyses, we identified 8 putative LOS protein ligands. Further investigation of these interactors led to the definition that LOS challenge is able to activate a signal transduction pathway that uses nodal regulators in common with salicylic acid-mediated pathway. Moreover, we proved evidence that Xcc LOS are responsible for oxidative burst in Arabidopsis either in infiltrated or systemic leaves. In addition, gene expression studies highlighted the presence of gene network involved in reactive oxygen species transduction pathway.

Abstract
PURPOSE To evaluate the effectiveness and safety of retrograde intrarenal surgery (RIRS) for stones up to 2 cm in diameter in patients with solitary kidney. METHODS From January 2008 to January 2013, we prospectively enrolled all consecutive patients with solitary kidney and renal stones. Plain abdominal computed tomography scan was performed preoperatively and 1 month after the procedure to assess the stone-free rates (SFR). Serum creatinine levels were detected preoperatively, at day 1 postoperatively, at 1 month postoperatively, and then every 6 months postoperatively. RESULTS During the study period, we prospectively enrolled a total of 29 patients. The mean age was 55.7 ± 12.3 years; the mean stone size was 1.3 ± 0.4 cm. The primary SFR was 72.4 %; the secondary SFR was 93.1 %. The mean number of procedures per patient was 1.24. The mean serum creatinine levels were 1.5 ± 0.6, 1.6 ± 0.7, 1.6 ± 0.6, and 1.7 ± 0.7 mg/dl preoperatively, at 1 day after RIRS, at 1 month after RIRS, and at 1 year after RIRS, respectively, without detection of any statistical difference (p = 0.76). Median follow-up time was 35.7 ± 19.3 (12-72) months, but that was available for only 18 patients. The mean serum creatinine level at the last follow-up was 1.7 ± 0.9 mg/dl. No major complications were recorded. Grade I complications occurred in eight patients (27.4 %). CONCLUSIONS RIRS is safe and effective in the treatment of renal stones in patients with solitary kidney, without worsening renal function.

Abstract
BACKGROUND AND PURPOSE Urinary symptoms associated with multiple sclerosis (MS) are common and negatively impact on quality of life, representing a considerable psychosocial and economic burden, often requiring care and hospitalization. Although the importance of identifying and adequately treating urinary symptoms in MS is now well recognized, there is no information, to date, about the real prevalence and impact of bladder symptoms in patients with clinically isolated syndromes (CISs) suggestive of MS. METHODS The aim of the present study was to investigate, in a cohort of patients with a diagnosis of CIS suggestive of MS, the prevalence of urinary tract symptoms, their impact on quality of life measures and their association with functional urodynamic dysfunctions. Patients underwent a complete neurological and urological visit, urodynamic investigation and the MSQoL-54 questionnaire. RESULTS Twenty-eight consecutive patients presenting with CISs were enrolled in the study; 53.6% of CIS patients reported urinary symptoms, 46.7% reporting irritative symptoms, 33.3% both irritative and obstructive symptoms and 20% obstructive symptoms alone. Urodynamic abnormalities were observed in 57.1% of the CIS patients. In 17.9% of the CIS patients urodynamic dysfunctions were asymptomatic. The presence of urinary symptoms was associated with lower scores on specific quality of life domains, particularly in women with obstructive symptoms. CONCLUSIONS A high prevalence of urinary symptoms and urodynamic dysfunctions in patients with CISs and an association of urinary symptoms with quality of life measures were found. These results highlight the importance of identifying and optimally treating urinary symptoms also at the very early stages of MS.

Abstract
BACKGROUND Although botulinum toxin (BoNT/A) injected into the detrusor muscle improves overactive bladder symptoms in patients with neurogenic detrusor overactivity, how it does so remains unclear. In this study, we investigated whether BoNT/A improves detrusor overactivity by modulating bladder afferent activity. METHODS To do so, during urodynamic assessment, we tested the soleus muscle Hoffmann (H) reflex during bladder filling before and after intradetrusor BoNT/A in patients with Parkinson's disease (PD) and in patients with complete chronic spinal cord lesion (SCI) and detrusor overactivity refractory to conventional therapy. Healthy subjects underwent H reflex studies during urodynamic assessment and acted as controls. RESULTS Our findings show that BoNT/A injected into the detrusor muscle effectively reduces clinical overactive bladder symptoms in patients with PD and SCI. In healthy subjects and patients with PD, bladder filling [at maximum cystometric capacity, (MCC)] significantly decreased the H reflex size, whereas in patients with SCI, it slightly facilitated the H reflex size. At MCC, in patients with PD, BoNT/A significantly reduced the expected H reflex inhibition, whereas in those with SCI, BoNT/A turned the H reflex facilitation at maximum bladder filling into a slight inhibition. CONCLUSIONS These findings show that BoNT/A injected into the detrusor muscle in patients with PD and SCI modulates bladder afferent activity. Modulation of bladder afferents possibly explains why BoNT/A improves detrusor overactivity.

Embryonic morphogenetic field induces phenotypic reversion in cancer cells. Review article. Curr Pharm Biotechnol 2011; 12:243-53.

Abstract
Cancer cells introduced into developing embryos can be committed to a complete reversion of their malignant phenotype. It is unlikely that such effects could be ascribed to only few molecular components interacting according to a simple linear-dynamics model, and they claim against the somatic mutation theory of cancer. Some 50 years ago, Needham and Waddington speculated that cancer represents an escape from morphogenetic field like those which guide embryonic development. Indeed, disruption of the morphogenetic field of a tissue can promote the onset as well as the progression of cancer. On the other hand, placing tumor cells into a "normal" morphogenetic field - like that of an embryonic tissue - one can reverse malignant phenotype, "reprogramming" tumor into normal cells. According to the theoretical framework provided by the thermodynamics of dissipative systems, morphogenetic fields could be considered as distinct attractors, to which cell behaviors are converging. Cancer-attractors are likely positioned somewhat close to embryonic-attractors. Indeed, tumors share several morphological and ultra-structural features with embryonic cells. The recovering of an "embryonic-like" cell shape might enable the gene regulatory network to reactivate embryonic programs, and consequently to express antigenic and biochemical embryonic characters. This condition confers to cancer an unusual sensitivity to embryonic regulatory cues. Thus, it is not surprising that cancer cells exposed to specific embryonic morphogenetic fields undergoes significant modifications, eventually leading to a complete phenotypic reversion.

Zebrafish stem cell differentiation stage factors suppress Bcl-xL release and enhance 5-Fu-mediated apoptosis in colon cancer cells. Curr Pharm Biotechnol 2011; 12:261-7.

Abstract
Stem cell differentiation stage factors (SCDSF), taken from Zebrafish embryos during the stage in which totipotent stem cells are differentiating into pluripotent stem cells, have been shown to inhibit proliferation and induce apoptosis in colon tumors. In order to ascertain if these embryonic factors could synergistically/additively interact with 5-Fluorouracil (5-Fu), whole cell-count, flow-cytometry analysis and apoptotic parameters were recorded in human colon cancer cells (Caco2) treated with Zebrafish stem cell differentiation stage factors (SCDSF 3 µg/ml) in association or not with 5-Fu in the sub-pharmacological therapeutic range (0.01 mg/ml). Cell proliferation was significantly reduced by SCDSF, meanwhile SCDSF+5-Fu leads to an almost complete growth-inhibition. SCDSF produces a significant apoptotic effect, meanwhile the association with 5-FU leads to an enhanced additive apoptotic rate at both 24 and 72 hrs. SCDSF alone and in association with 5-Fu trigger both the extrinsic and the intrinsic apoptotic pathways, activating caspase-8, -3 and -7. SCDSF and 5-Fu alone exerted opposite effects on Bax and Bcl-xL proteins, meanwhile SCDSF+5-Fu induced an almost complete suppression of Bcl-xL release and a dramatic increase in the Bax/Bcl-xL ratio. These data suggest that zebrafish embryo factors could improve chemotherapy efficacy by reducing anti-apoptotic proteins involved in drug-resistance processes.

Cross activity of orthologous WRKY transcription factors in wheat and Arabidopsis. JOURNAL OF EXPERIMENTAL BOTANY 2011; 62:1975-90.

Abstract
WRKY proteins are transcription factors involved in many plant processes including plant responses to pathogens. Here, the cross activity of TaWRKY78 from the monocot wheat and AtWRKY20 from the dicot Arabidopsis on the cognate promoters of the orthologous PR4-type genes wPR4e and AtHEL of wheat and Arabidopsis, respectively, was investigated. In vitro analysis showed the ability of TaWRKY78 to bind a -17/+80 region of the wPR4e promoter, containing one cis-acting W-box. Moreover, transient expression analysis performed on both TaWRKY78 and AtWRKY20 showed their ability to recognize the cognate cis-acting elements present in the wPR4e and AtHEL promoters, respectively. Finally, this paper provides evidence that both transcription factors are able to cross-regulate the orthologous PR4 genes with an efficiency slightly lower than that exerted on the cognate promoters. The observation that orthologous genes are subjected to similar transcriptional control by orthologous transcription factors demonstrates that the terminal stages of signal transduction pathways leading to defence are conserved and suggests a fundamental role of PR4 genes in plant defence. Moreover, these results corroborate the hypothesis that gene orthology imply similar gene function and that diversification between monocot and dicot has most likely occurred after the specialization of WRKY function.

Effect of botulinum neurotoxin on the urinary bladder: novel insights on mechanism of action. MINERVA UROL NEFROL 2010; 62:259-271.

Abstract
Botulinum neurotoxins (BoNTs) recently tarted to be used in common urologic practice for the treatment of neurogenic and non neurogenic detrusor overactivity (DO) refractory to all conventional treatments. The rationale was that botulinum toxin, particularly BoNT type A (BoNT/A), was able to block the presynaptic release of acetylcholine (ACh) from the parasympathetic efferent nerves thus paralyzing the detrusor smooth muscle, an action similar to that performed in skeletal muscles. With the present review we aimed at assessing the state of the art on the mechanisms of function of botulinum toxins in the management of urological dysfunctions. We searched PubMed using the medical subject heading (MeSH) term botulinum toxin in conjunction with any of the following terms: mechanism of action, bladder, afferent and efferent nervous transmission, urothelium and suburothelium, detrusor overactivity. Review articles and published abstracts were identified by limiting for review and abstract, respectively. The reference list of review and original papers were reviewed to identify any missed papers. A similar search strategy was applied in EMBASE using identical EMTREE terms. Recent evidences in in vivo and in in vitro studies suggest that in addition to a direct effect on detrusor motor innervation, BoNT/A also modulates intrinsic bladder reflexes through a multimodal effect on sensory pathways. Such mechanisms may contribute to the efficiency of this treatment and partly explain how it affects abnormal detrusor contractions more markedly than voluntary bladder emptying.

Abstract
Spinosad, a naturally occurring product of the fermentation of the bacterium Saccharopolyspora spinosa, is a highly effective bioinsecticide against a broad range of agriculturally important insect pests, and this agent has an excellent environmental and mammalian toxicological profile. In this study the efficacy of a Spinosad-based product (Laser 4.8% emulsifiable concentrate) was evaluated in laboratory bioassays against laboratory-reared mosquito strains of 3 species of medical importance: Aedes aegypti, Anopheles stephensi, and Culex pipiens. Spinosad was particularly effective against larval Aedes and Culex, with a less marked activity against anophelines (24-h median lethal concentration = 0.0096, 0.0064, and 0.039 mg/liter, respectively), showing a persistence of the insecticide action of about 6 wk in laboratory containers. The activity of the Spinosad-based product against adult mosquitoes (toxicity by ingestion and a possible irritant or repellent effect on gravid females) also was evaluated. Results are discussed and compared with those available in the literature.

Abstract
UNLABELLED Perturbation of respiratory mechanics produced by general anesthesia and surgery is more pronounced in morbidly obese (MO) patients. Because general anesthesia induces pulmonary atelectasis in nonobese patients, we hypothesized that atelectasis formation would be particularly significant in MO patients. We investigated the importance and resorption of atelectasis after general anesthesia in MO and nonobese patients. Twenty MO patients were anesthetized for laparoscopic gastroplasty and 10 nonobese patients for laparoscopic cholecystectomy. We assessed pulmonary atelectasis by computed tomography at three different periods: before the induction of general anesthesia, immediately after tracheal extubation, and 24 h later. Already before the induction of anesthesia, MO patients had more atelectasis, expressed in the percentage of the total lung area, than nonobese patients (2.1% versus 1.0%, respectively; P < 0.01). After tracheal extubation, atelectasis had increased in both groups but remained significantly more so in the MO group (7.6% for MO patients versus 2.8% for the nonobese; P < 0.05). Twenty-four hours later, the amount of atelectasis remained unchanged in the MO patients, but we observed a complete resorption in nonobese patients (9.7% versus 1.9%, respectively; P < 0.01). General anesthesia in MO patients generated much more atelectasis than in nonobese patients. Moreover, atelectasis remained unchanged for at least 24 h in MO patients, whereas atelectasis disappeared in the nonobese. IMPLICATIONS We compared the resolution over time of pulmonary atelectasis after a laparoscopic procedure by performing computed tomography scans in two different groups of patients: 1 group had 10 nonobese patients, and in the other group there were 20 morbidly obese patients.

Abstract
The study aimed to estimate the pain related to first trimester abortion under local and general anaesthesia. One hundred and eighty-one women undergoing abortion of first trimester under local anaesthesia and 198 under general anaesthesia were interviewed 1 h after the end of the procedure. About 50% of all women described their experience as less painful than expected. Over 50% of the women described the pain during the procedure as mild or moderate according to the verbal rating scale. The step-up logistic regression analyses identified four important variables: time interval less than 2 min from local anaesthesia injection to the beginning of the procedure (RR = 3), lack of choice between local and general anaesthesia (RR = 1.9), history of frequent use of analgesics (RR = 1.9) and nulliparity (RR = 1.7). These data indicate that skillfully performed abortion with local anaesthesia is a procedure tolerated by most women. Moreover, because it carries lower risk of complications and costs less, its use should be encouraged.

Abstract
The authors herein present their personal series on the clinical evaluation of the analgesic efficacy of 2 opiodes, peridural morphine hydrochloride (0.5 mg/kg) administered to group A patients, and sublingual buprenorphine (0.4 mg) administered to group B patients in the management of post-operative pain in major abdominal surgery. The study was conducted on 44 patients, both male and female, classified as ASA II and III. Statistical analysis of cardiovascular parameters (BP and cardiac frequency), respiratory frequency and pain score showed an overlapping progression among the two groups. Spontaneous pain decreased significantly to zero at T6 (p < 0.001). However, the necessity to administer buprenorphine more frequently after the sixth hour and the consequent increase in side effects, lead us to believe that the method used for group A patients is more advantageous.

Abstract
We herein evaluated the analgesic effectiveness of low doses of buprenorphine with or without a primer and the practicality and usefulness of a constant flow disposable infusion set (Infusor Baxter 2 ml/h). Our series consists of 300 patients, seen between January 1992 and December 1993, randomly distributed in three groups of 100 patients each. All patients were informed before operation about the use of pain Visual Analogical Scale (VAS) and how the infusor works. At the end of the operation all patients had an infusor positioned with a 0.01 mg/kg supplied of buprenorphine diluted to 60 ml with Ringer's Lactate solution. In addition to this, group B patients received an i.v. primer of 0.003 mg/kg of buprenorphine diluted to 10 ml with saline solution and group C patients received an i.v. primer of 0.5 mg/kg of ketorolac diluted to 10 ml with saline solution. VAS, systolic arterial pressure, diastolic arterial pressure, heart rate, respiratory rate, request of analgesics and side effects were evaluated at one hour (T0), six hours (T1), 12 hours (T2), 24 hours (T3) and 36 hours (T4) after operation. Group B and C patients showed significant reduction in VAS compared to group A patients at T0 and T1 but the difference disappeared starting from T2. Group B and C patients showed blood pressure, heart rate and respiratory rate values significantly reduced compared to group A patients at T0 and T1. Such values however then stabilized. Side effects encountered were nausea and vomiting in different percentages in the three groups.(ABSTRACT TRUNCATED AT 250 WORDS)
