Ultrasound-assisted Thoracic Intervertebral Foramen Block. A Cadaveric Study.

BACKGROUND: A thoracic paravertebral block can be a useful opioid-sparing technique for controlling postoperative pain after thoracic and visceral abdominal surgery. OBJECTIVES: Our aim was to assess dye spread into the ventral branch, connecting branch, sympathetic trunk, thoracic paravertebral space, and epidural space after performing a modified ultrasound-assisted thoracic paravertebral block via the intervertebral foramen. STUDY DESIGN: This was a nonrandomized cadaveric study. SETTING: The cadavers were kept at the Department of Anatomopathology of the San Salvatore Academic Hospital of L'Aquila (L'Aquila, Italy). METHODS: We performed a bilateral thoracic paravertebral block via the intervertebral foramen at the second, fifth, ninth, and twelfth thoracic vertebrae. A linear array ultrasound transducer was used. Then, cadaveric dissection was performed. A Tuohy needle was gently inserted in-plane with the ultrasound beam in a lateromedial direction to contact the spinous process. Subsequently, the needle tip was advanced 2 mm along the transverse process of the vertebra, and 5 mL of methylene blue 1% dye was injected at each level. Then, 2 continuous catheter sets were inserted. RESULTS: Forty intervertebral foramen blocks were performed in 5 cadavers. For 38 injection sites, we found dye on both sides of the thoracic paravertebral space and epidural space at each level of puncture. The retropleural organs were also stained. In 2 cases, methylene blue accumulated intramuscularly at the level of the twelfth thoracic vertebra. RESULTS: The spread of dye into the ventral rami, communicating rami, and sympathetic trunk in the thoracic paravertebral space and the epidural space was assessed. We also evaluated the position and the distance (mm) between the catheter tip and the thoracic intervertebral foramen content. Finally, puncturing of intervertebral blood vessels, nerve rootlet and root damage, lung and pleural injuries, and the extent of intramuscular dye accumulation were evaluated and recorded as iatrogenic complications related to the anesthetic procedure. Forty thoracic paravertebral blocks in 5 cadavers were performed. For 38 injection sites, we found dye on both sides of the thoracic paravertebral space and the epidural space at each level of puncture. The ventral rami, the communicating rami, and the sympathetic trunk were also stained. In 2 cases, methylene blue accumulated intramuscularly at the level of the twelfth thoracic vertebra. LIMITATIONS: The first limitation of this study is its small sample size. In addition, the study design did not consider or measure the width of the transverse processes. Another limitation is that the ultrasound beam could not identify the thoracic intervertebral foramen content or the needle tip behind the acoustic shadow of the transverse and vertebral articular processes. CONCLUSION: Paravertebral block via the thoracic intervertebral foramen achieved consistent dye spread into the thoracic paravertebral space and epidural space, capturing retropleural organs.

Investigating Unhealthy Behaviors Associated with SF-36 Domains in Women with Endometriosis-Findings from a Web-Based Survey Data Set.

Unhealthy behaviors may contribute to the development and the progression of chronic diseases with negative consequences on patients' quality of life. The present study aimed to investigate the relationship between unhealthy behaviors (physical inactivity, tobacco consumption, and alcohol consumption) and health-related quality of life, measured with the SF-36 questionnaire, in women with endometriosis. To achieve this, data from a previous cross-sectional web survey among Italian adult women were analyzed. A total of 1045 responses were included in the analysis. Among the SF-36 subscales, the lowest score was recorded in the energy/fatigue domain: mean = 35.536 (Standard Deviation = 18.452). Smoking and physically inactive women had lower scores than non-smoking and physically active women, respectively, in each SF-36 domain. Women who drank more than one unit of alcohol a day, on average, reported lower scores than women with an alcohol intake <1 unit a day, for the following SF-36 domains: role limitations due to physical health, role limitations due to emotional problems, and emotional well-being. The multivariable analysis evidenced that employment, physical inactivity, and tobacco consumption were significant predictors for each SF-36 domain (p < 0.05). Physical inactivity and tobacco consumption had negative effects on the SF-36 subscales. Our results showed the need to monitor unhealthy behaviors to improve the overall well-being of women with endometriosis. Tailored strategies addressing smoking cessation, promoting physical activity, and moderating alcohol intake may aid in enhancing health-related quality of life in this vulnerable population.

Safety and effectiveness of prilocaine for spinal anesthesia in day surgery setting: a retrospective study on a sample of 3291 patients.

Spinal anesthesia is considered safe and reliable for most surgical procedures involving the lower part of the body, but its use in the ambulatory setting requires drugs with rapid onset and regression of the motor and sensory block-like prilocaine.The purpose of this study is to retrospectively analyze data from 3291 procedures recorded in our institutional database, to better define the safety profile of spinal prilocaine and the incidence of complications and side effects.All clinical data, prospectively collected from 2011 to 2019 in an Italian tertiary hospital, of patients treated with spinal anesthesia performed with 40 mg of hyperbaric 2% prilocaine, according to our internal protocol of day surgery, were analyzed.Surgical procedures included saphenectomy (28.5%, n = 937), knee arthroscopy (26.8%, n = 882), proctologic surgery (15.16%, n = 499), and inguinal canal surgery (14.9%, n = 491).Anesthesia-related complication was represented by urinary retention (1.09%, n = 36), lipotimia (0.75%, n = 25), and postoperative nausea (0.33%, n = 11); arrhythmic events were uncommon (0.18%, n = 6). One case of persistent hypotension and 2 cases of persistent hypertension were reported.Persistent motor or sensory block (lasting more than 5 h) was experienced by 7 patients. One patient (0.03%), who underwent knee arthroscopy, experienced pelvic pain lasting for 6 h, compatible with a transient neurological symptom.Proctologic surgery was a factor associated with unplanned admission due to anesthesia-related complications (OR = 4.9; 95% CI: 2-14%).The number of complications related to the method was low as well as the need for hospitalization. This drug is valid and safe for the most performed day surgery procedures; however, further trials are needed to investigate the incidence of complications in the days following the procedure.

Excisional Hemorrhoidectomy Versus Dearterialization With Mucopexy for the Treatment of Grade III Hemorrhoidal Disease: The EMODART3 Multicenter Study.

BACKGROUND: Over the past few decades, several surgical approaches have been proposed to treat hemorrhoids. OBJECTIVE: This multicenter study aimed to compare transanal hemorrhoidal artery ligation and conventional excisional hemorrhoidectomy for grade III hemorrhoidal disease. DESIGN: Multicenter retrospective study. SETTINGS: Any center belonging to the Italian Society of Colorectal Surgery in which at least 30 surgical procedures per year for hemorrhoidal disease were performed was able to join the study. PATIENTS: Clinical data from patients with Goligher's grade III hemorrhoidal disease who underwent excisional hemorrhoidectomy or hemorrhoidal artery ligation were retrospectively analyzed after a 24-month follow-up period. MAIN OUTCOME MEASURES: The primary aims were to evaluate the adoption of 2 different surgical techniques and to compare them in terms of symptoms, postoperative adverse events, and recurrences at a 24-month follow-up. RESULTS: Data from 1681 patients were analyzed. The results of both groups were comparable in terms of postoperative clinical score by multiple regression analysis and matched case-control analysis. Patients who underwent excisional hemorrhoidectomy had a significantly higher risk of postoperative complication (adjusted OR = 1.58; p = 0.006). A secondary analysis highlighted that excisional hemorrhoidectomy performed with new devices and hemorrhoidal artery ligation reported a significantly lower risk for complications than excisional hemorrhoidectomy performed with traditional monopolar diathermy. At the 24-month follow-up assessment, recurrence was significantly higher in the hemorrhoidal artery ligation group (adjusted OR = 0.50; p = 0.001). A secondary analysis did not show a higher risk of recurrences based on the type of device. LIMITATIONS: The retrospective design and the self-reported nature of data from different centers. CONCLUSIONS: Hemorrhoidal artery ligation is an effective option for grade III hemorrhoidal disease; however, it is burdened by a high risk of recurrences. Excisional hemorrhoidectomy performed with newer devices is competitive in terms of postoperative complications.HEMORROIDECTOMÍA POR ESCISIÓN VERSUS DESARTERIALIZACIÓN CON MUCOPEXIA PARA EL TRATAMIENTO DE LA ENFERMEDAD HEMORROIDAL DE GRADO 3: EL ESTUDIO MULTICÉNTRICO EMODART3ANTECEDENTES:En las últimas décadas se han propuesto varios abordajes quirúrgicos para el tratamiento de las hemorroides.OBJETIVO:Este estudio multicéntrico tiene como objetivo comparar la ligadura de la arteria hemorroidal transanal y la hemorroidectomía por escisión convencional para la enfermedad hemorroidal de grado III.DISEÑO:Estudio retrospectivo multicéntrico.ÁMBITO:Cualquier centro perteneciente a la Sociedad Italiana de Cirugía Colorrectal en el que se realizaron al menos 30 procedimientos quirúrgicos por año para la enfermedad hemorroidal pudo participar en el estudio.PACIENTES:Los datos clínicos de pacientes con enfermedad hemorroidal de grado III de Goligher que se sometieron a hemorroidectomía por escisión o ligadura de arterias hemorroidales se analizaron retrospectivamente después de un período de seguimiento de 24 meses.PRINCIPALES MEDIDAS DE RESULTADO:Los objetivos primarios fueron evaluar la adopción de dos técnicas quirúrgicas diferentes y compararlas en términos de síntomas, eventos adversos posoperatorios y recurrencias a los 24 meses de seguimiento.RESULTADOS:Se analizaron datos de 1681 pacientes. Los 2 grupos resultaron ser comparables en términos de puntuación clínica posoperatoria mediante análisis de regresión múltiple y análisis de casos y controles emparejados. Los pacientes sometidos a hemorroidectomía excisional tuvieron un riesgo significativamente mayor de complicaciones posoperatorias (odds ratio ajustado = 1,58; p = 0,006). Un análisis secundario destacó que la hemorroidectomía por escisión realizada con nuevos dispositivos y la ligadura de la arteria hemorroidal informaron un riesgo significativamente menor de complicaciones que la hemorroidectomía por escisión realizada con diatermia monopolar tradicional. En la evaluación de seguimiento de 24 meses, la recurrencia fue significativamente mayor en el grupo de ligadura de la arteria hemorroidal (razón de probabilidad ajustada = 0,50; p = 0,001). Un análisis secundario no mostró un mayor riesgo de recurrencias según el tipo de dispositivo.LIMITACIONES:El diseño retrospectivo y el carácter autoinformado de los datos de diferentes centros.CONCLUSIÓN:HAL es una opción efectiva para la enfermedad hemorroidal grado III; sin embargo, se ve afectado por un alto riesgo de recurrencias. La hemorroidectomía por escisión realizada con dispositivos más nuevos es competitiva en términos de complicaciones posoperatorias. (Traducción-Dr Yolanda Colorado ).

Emotional arousal and valence in patients with fibromyalgia: a pilot study.

The pathogenesis of pain in fibromyalgia is still not completely understood. A disrupted emotional modulation could affect the physiology of nociception and contributes to an altered perception of pain. The aim of this study was to test the role of emotional arousal and valence in pain susceptibility in fibromyalgia using the International Affective Picture System (IAPS) paradigm and the Fibromyalgia Severity Scale (FSS). The study focused on comparing emotional arousal and valence between patients with fibromyalgia and the control group. The secondary objective was to examine the correlation between emotional indices and scores on the FSS and the duration of the disease. The 20 patients with fibromyalgia enrolled showed a higher mean arousal score for all the stimuli, including a higher score for unpleasant and socially unpleasant stimuli. The valence scores for social-relevant stimuli were also higher. Increased arousal to unpleasant and socially unpleasant images and increased valence of them correlated with the duration of the disease and the severity of symptoms and could reflect impairment in social cognition and marked sensitivity to pain in interaction with central nociceptive dysregulation.

Arterial Blood Gas and Rotational Thromboelastometry Parameters in Healthy Rescuers Incidentally Exposed to Nitroglycerin, Nitrogen Compounds, and Combustion Products.

INTRODUCTION: Acute exposure to nitrogen compounds combined with a massive inhalation of air pollutants can influence respiratory and cardiovascular symptoms and coagulation abnormalities in accidentally exposed healthy adults during cave detonation operations. METHODS: Italian alpine and cave rescuers widened a cave in the Abisso Luca Kralj in Trieste, Italy. Volunteers inside the cave were accidentally exposed to the fumes from an uncontrolled detonation of blasting gelatin microcharges. We performed a retrospective cohort study on the clinical data, arterial blood gas analysis, and rotational thromboelastometry parameters from the rescuers involved in the accident. RESULTS: Ninety-three healthy rescuers were involved in the uncontrolled detonation: 47 volunteers handled a mixture of nitrogen compounds (blaster group), and 46 volunteers did not (nonblaster group). After the accident, statistically significant differences (P<0.05) in arterial blood gas values were observed between the groups, with a pattern of mild respiratory acidosis with hypercapnia in the nonblaster group and severe mixed acid-base disorder with hypoxia and hypercapnia in the blaster group. Mild hyperfibrinolysis was observed in 44 volunteers in the blaster group, as were associated bleeding symptoms in 34 volunteers; no significant coagulation modifications were recorded in the nonblaster group. CONCLUSIONS: Respiratory acidosis with hypoxia, hypercapnia, a compensatory metabolic response, and mild hyperfibrinolysis were probably related to the combined effect of nitrogen compounds and the inhaled toxic products of detonation. Therefore, each element exerts a determinant effect on promoting the biological toxicity of the others.

Knowledge and attitudes of Italian medical oncologists and palliative care physicians toward medical use of cannabis in cancer care: a national survey.

PURPOSE: Despite advances in supportive care, cancer-related symptoms tend to be persistent regardless of cancer type, stage of disease, or treatment received. There is an increasing prescription for complementary and alternative medicines, such as medical cannabis (MC). Knowledge and attitudes of Italian medical oncologists and palliative care physicians toward medical cannabis in cancer care remain unknown. METHODS: We conducted a cross-sectional study to investigate the knowledge and attitude toward MC prescription among cancer care professionals in Italy. All invited participants received an email with the electronic questionnaire accessible through a direct link. RESULTS: Among the 2616 members who received the invitation, 475 replied to the questionnaire and were considered for the survey analysis. The most prescribed formulations among those available in Italy were cannabis FM2. The most frequent clinical indications for the use of MC were pain, gastrointestinal, and mood disorders. Only 9 responders reported MC-related side effects like anxiety insomnia and muscle spasms. The question regarding the normative references for MC prescription and use in Italy had conflicting results: only 14% indicated the exact legislative reference. CONCLUSION: Our study highlights a significant discrepancy between personal attitudes, prescription levels, and actual knowledge on MC. This represent a critical issue that should be systemically faced, building educational programs and national guidelines that sublimate personal physicians' beliefs and predispositions, resulting in a robust science-based MC practice. Only through coordinated interventions on science and health policy of MC, there will be success of safety and efficacy, ensuring the best knowledge for the best outcomes.

Proctologic Surgery Prioritization After the Lockdown: Development of a Scoring System.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic has shown a very critical impact on surgical procedures all over the world. Italy faced the deepest impact from the beginning of March 2020. Elective operations, screening, and follow-up visits had been suspended giving priority to urgent and oncologic surgery. PATIENTS: An observational study was carried out in the Surgical Coloproctology Unit of the Val Vibrata Hospital on 152 patients awaiting a proctological surgical treatment during the national lockdown. METHODS: In order to monitor the health status of patients and reschedule postlockdown surgical activities, patients were interviewed by telephone submitting a questionnaire based upon the judgment of an expert senior clinician. Following the interview, we calculated a severity index for all the proctologic diseases (hemorrhoidal disease, anal fissure, anal sepsis, slow transit or obstructed defecation, incontinence), classifying the patients according to the score. Mean age of patients was 53 (±16) years, and there were 84 males (55.3%) and 68 females (44.7%). In total, 31% of our patients suffered from anal fissure, 28% suffered from hemorrhoidal disease, 14% suffered from anal sepsis, and the remaining patients suffered from benign anorectal diseases to a lesser extent. RESULTS: A total of 137 patients were available and divided into three classes: priority surgery (PS) with 49 patients (36.2%), deferrable surgery (DS) with 25 patients (18.1%), and long-term surgery (L-TS) with 63 patients (45.6%). There was a significant correlation between the perceived health status reported during the interview and the priority class index (Spearman's rho = 0.97, p < 0.001).Differences related to age and sex were not significant (F-test = 0.43, p = 0.653; chi-squared test = 0.693, p = 0.707). 49 patients in class PS needed a prompt surgical treatment, while 24 patients allocated in class DS and 65 patients allocated in class L-TS could wait for a new ride plan for surgery. CONCLUSION: New tools, such as this simple score obtained during the telephone interview, can be useful for prioritization of patients on the waiting list for surgical coloproctology after the lockdown without further clinical examination and hospital access.

A systematic review of contralateral carotid stenosis progression after carotid endarterectomy.

OBJECTIVE: Progression of contralateral carotid artery stenosis after carotid endarterectomy (CEA) has been described by several authors. The aim of this study is to determine such disease progression and its related transient ischemic attacks (TIAs) or strokes by reviewing the existing literature. METHODS: We performed a systematic literature review to select randomized controlled trials and observational studies reporting outcomes of patients treated by CEA and with concomitant contralateral carotid stenosis, regardless its degree of stenosis. The study was registered in the International Prospective Register of Systematic Reviews (PROSPERO registration number: CRD42019127595). The primary study end point was the progression of contralateral carotid artery stenosis after CEA, and the secondary end point was incidence of TIAs and strokes owing to contralateral carotid stenosis. RESULTS: Seventeen studies were retrieved, reporting data on a total of 7679 patients who had undergone CEA, in particular they were one post hoc analysis of a randomized controlled trial, nine prospective, and seven retrospective observational studies. Among these patients, follow-up information on the contralateral carotid artery was available for 5454 cases. Disease progression was observed in 18% of patients: single class progression from mild (<50%) and from moderate (50%-70%) stenosis was observed in 15% and 23% of cases, respectively. We found 105 TIAs (4%) and 88 strokes (3%) among 2781 patients with stenosis progression, based on result from 11 studies. CONCLUSIONS: We found a progression of contralateral carotid stenosis in a significant number of patients treated with CEA and with baseline carotid stenosis. This systematic literature review suggests that patients with moderate contralateral carotid stenosis demonstrate more rapid progression to significant or symptomatic stenosis than patients with mild contralateral stenosis.

Intermediate Cervical Plexus Block in the Management of Persistent Postoperative Pain Post Carotid Endarterectomy: A Prospective, Randomized, Controlled, Clinical Trial.

BACKGROUND: The mechanisms of persistent postoperative pain (PPP) with neuropathic features after carotid endarterectomy (CEA) are multifaceted and are incompletely understood. OBJECTIVES: The aim of this research was to assess whether the ultrasound-guided (USG) intermediate cervical plexus block (ICPB) could provide better control of PPP and neuropathic disturbances (NPDs) after CEA than the USG superficial cervical plexus block (SCPB). STUDY DESIGN: Prospective, randomized, controlled, clinical trial. SETTING: This clinical trial was conducted at the SS Filippo and Nicola Academic Hospital of Avezzano (L'Aquila, Italy). METHODS: Patients who were scheduled for primary CEA were chosen. In the experimental group, the USG-ICPB was performed unilaterally, at the level of the third cervical vertebra. The needle was inserted into the deep lamina of the deep fascia of the neck, between the posterior border of the middle scalene muscle and the anterior border of the posterior scalene muscle. Three milliliters saline solution was injected into the opening of the deep lamina, and 20 mL 0.375% levobupivacaine was injected. In the control group, the anesthetic target was located at the inferior border of the sternocleidomastoid muscle at the level of the third cervical vertebra. The needle was superficially inserted below the skin, and 2 to 3 mL saline solution was injected into the opening of the superficial lamina of the deep fascia of the neck. A total of 20 mL 0.375% isobaric levobupivacaine was subsequently injected.The primary outcome measure was the proportion of patients with PPP on movement and at rest 3 months after surgery. The secondary outcome measures were NPD assessment scores using the von Frey hair test and the Lindblom test, opioid and pregabalin consumption. Adverse effects were also recorded. RESULTS: A total of 98 consecutive patients were enrolled and randomized to receive either a USG-SCPB (control group, n = 49) or a USG-ICPB (experimental group, n = 49). The sensory blockade was longer in the experimental group. Three months after surgery, the proportions of patients with PPP on movement were significantly different between the experimental and control groups (33%, 95% confidence intervals [CI], 20%-47% vs. 71%, 95% CI, 57%-83%; P < 0.001), whereas there were no differences in the proportions of patients with pain at rest between groups (31%, 95% CI, 18%-45% vs. 49%, 95% CI, 34%-64%; P = 0.063). The proportions of patients with NPDs were not different between the groups, whereas the sizes of the areas of interest (cm2) were significantly different. LIMITATIONS: A limitation of this study is that we assessed NPDs for only 3 months using the von Frey hair test and the Lindblom test without additional instrumental techniques. Additionally, there are many risk factors for NPDs after CEA. For this reason, another limitation of this research is that we neglected to consider the relationship between the choice of anesthetic block and the presence of these risk factors. CONCLUSIONS: The USG-ICPB provided long-lasting analgesia during the postoperative period and might mitigate the development of NPDs, thereby decreasing the analgesic drug requirement. KEY WORDS: Carotid endarterectomy, intermediate cervical plexus block, myofascial planes of neck, neuropathic disturbances, persistent postoperative pain, superficial cervical plexus blocks, ultrasound guidance, vascular disease.

Continuous Wound Infiltration of Local Anesthetics in Postoperative Pain Management: Safety, Efficacy and Current Perspectives.

Local infiltration and continuous infusion of surgical wound with anesthetics are parts of multimodal analgesia for postoperative pain control. The techniques, given the simplicity of execution that does not increase the timing of the intervention and does not require additional technical skills, are applied in several kinds of surgeries. The continuous wound infiltration can be used for days and a variety of continuous delivery methods can be chosen, including patient-controlled analgesia, continuous infusion or intermittent bolus. The purpose of this narrative review is to analyze the literature, in particular by researching the safety, efficacy and current perspectives of continuous wound infiltration for postoperative pain management in different surgical settings. We have identified 203 articles and 95 of these have been taken into consideration: 17 for the lower limb surgery; 7 for the upper limb surgery, 51 for the laparotomy/laparoscopic surgery of the abdominopelvic area, 13 studies regarding breast surgery and 7 for cardiothoracic surgery. The analysis of these studies reveals that the technique has a variable effectiveness based on the type of structure involved: it is better in structures rich in subcutaneous and connective tissue, while the effectiveness is limited in anatomic districts with a greater variability of innervation. However, regardless the heterogeneity of results, a general reduction in pain intensity and in opioid consumption has been observed with continuous wound infiltration: it is an excellent analgesic technique that can be included in the multimodal treatment of postoperative pain or represents a valid alternative when other options are contraindicated.

The PERSONS score: A new tool for cancer patients' symptom assessment in simultaneous care and home care settings.

BACKGROUND: Scientific societies recommend early interaction between oncologic and supportive care, but there is still a lack of systematic evaluations regarding symptoms from the perspective of oncologists. PATIENTS AND METHODS: The aim of this prospective study was to evaluate the PERSONS score, in both "simultaneous care" and "supportive care" settings using the Edmonton Symptom Assessment Scale (ESAS) as a comparator. RESULTS: From November 2017 to April 2018, 67 and 110 consecutive patients were enrolled in outpatient and home care cohorts, respectively. The final study population comprised 163 patients. There were no significant changes over time in the total PERSONS scores and total ESAS scale. The intra-interviewer reliability (ICC2,1) and inter-interviewer reliability (ICC2,k) showed good reproducibility (test-retest) in each group of patients: 0.60 (0.49-0.70) and 0.82 (0.75-0.87), respectively, for the home care patients and 0.73 (0.62-0.81) and 0.89 (0.83-0.93), respectively, for the outpatient cohort. There were high correlations between PERSONS and ESAS, both at the baseline and final assessments. The mean PERSONS and ESAS scores between the home care patients and outpatients were not different at the baseline and final assessments. Receiver operating characteristics (ROC) curve for the PERSONS total score revealed good diagnostic ability. Area under the curve (AUC) was 0.825 and 0.805 for improvement and deterioration, respectively. CONCLUSIONS: The PERSONS score is an easy to apply tool for symptom assessment. Importantly, the PERSONS score showed high concordance with the established ESAS scale and, therefore, provides an alternative for everyday use in supportive care assessment.

What cancer patients actually know regarding medical cannabis? A cross-sectional survey with a critical analysis of the current attitudes.

BACKGROUND: In Italy medical cannabis is a prescription drug since 1998. Even though it could not be considered a therapy as such, it is indicated as a symptomatic treatment also in cancer patients, to cure iatrogenic nausea/vomiting and chronic pain. PATIENTS AND METHODS: We conducted a knowledge survey about medical cannabis among cancer patients referred to two outpatient cancer care centers and a home care service. RESULTS: From February to April 2018, 232 patient were enrolled; 210 patients were on active disease-oriented treatment (90.5%), while 22 (9.5%) not. Eighty-one percent of the patients have heard about medical cannabis, but only 2% from healthcare professionals. Thirty-four percent of responders thought about using cannabis to treat one or more of their own health problems, especially pain (55%). Despite that, 18% of the participants believe that medical cannabis could have negative effects on their own symptoms. Patients with high educational level better knew cannabis (odds ratio = 3.52; 95% confidence interval: 1.07-11.53), and medical cannabis (odds ratio = 3.21; 95% confidence interval: 1.48-6.98), when compared to patient with low educational level. Patients who were on active disease-oriented treatment better knew medical cannabis (odds ratio = 3.91; 95% confidence interval: 1.26-12.11) compared to "out of treatment" patients. Metastatic patients were less informed about medical cannabis compared to patients on adjuvant treatment. CONCLUSIONS: Our survey shows that most of Italian cancer patients know medical cannabis and a third of them have considered using cannabis to treat one (or more) of their own health problems. In the same time, they are poorly informed and do not tend to ask for information about medical cannabis to healthcare professionals.

Endovenous Laser Ablation with 1,470-nm Diode with Tumescence Anesthesia and Saphenofemoral Ligation: Propensity Score Match Comparison.

BACKGROUND: The aim of this study is to compare 2 groups of patients treated for great saphenous vein (GSV) reflux with open surgical saphenofemoral ligation (SFL) and endovenous laser ablation (EVLA). METHODS: Consecutive patients with primary unilateral GSV reflux undergoing EVLA treatment since 2014 were enrolled, and another series of patients treated with SFL was considered. The patients were stratified according to treatment and the results were compared using the propensity score (1:1). The covariables were age, gender, body mass index, CEAP (Clinical class, Etiology, Anatomy and Pathophysiology) staging, and GSV and saphenofemoral junction diameters. Primary outcomes were GSV occlusion or recurrent groin varicose veins at 1 year after treatment. Secondary outcomes included vein thrombosis, hyperpigmentation, paresthesia, postoperative pain, analgesic requirement, and ecchymosis assessed at discharge and CEAP stage and quality of life (QoL) assessment 1 month after surgery. RESULTS: A total of 123 patients were included in the study: 59 were treated with EVLA and 64 with SFL. At 12 months, we observed 10 recurrent groin varicose veins after SFL (15.6%) and 6 GSV recanalization after EVLA (10.2%, P = 0.369). Extra-saphenous recurrent varicose veins were observed in 36 patients (29.3%): 20 in the open group (31.2%) and 16 in EVLA group (27.1%, P = 0.615). After matching procedure 74 patients were analyzed (37 patients by group), logistic regression model showed that the risk of outcome was not associated with the surgical treatment (odds ratio 1.76, 95% confidence interval 0.52-6.01). CONCLUSIONS: Both techniques to treat saphenous impairment have demonstrated to be safe, with good results in terms of efficacy and symptomatic improvement at follow-up. EVLA with 1,470 nm seems to have lower rates of recurrence and good perceived QoL. Tumescent anesthesia is a good option with good results and may be extended to open surgical ligation.

Energy drinks consumption in Italian adolescents: preliminary data of social, psychological and behavioral features.

BACKGROUND: The aim of this study was to investigate the prevalence of energy drink (ED) consumption and the associations with social, psychological and behavioral features among an Italian adolescent sample. METHODS: A cross-sectional prevalence study of 450 Italian adolescents attending middle school was conducted. The Italian versions of the European Food Safety Authority's adolescent Energy Drinks Questionnaire and of the Depression and Anxiety in Youth Scale (DAYS) were administered to evaluate ED use and its psychological correlates. Odds ratios (OR) with 95% confidence intervals (CI) were calculated using a logistic model to estimate the associations between ED consumption and socio-demographic characteristics, psychological factors and risky behaviors. RESULTS: The prevalence of ED consumers was 57%, of whom 49% used alcohol mixed with ED. A total of 9% exhibited high chronic consumption, 31% average chronic consumption and 8% high acute consumption. Males were significantly more likely to use ED (OR=2.7, 95% CI: 1.8-4.0, P=0.00) and to engage in high acute consumption (OR=4.0, 95% CI: 1.1-13.8, P=0.03). Regular smoking was associated with ED use (OR=3.4, 95% CI: 1.2-9.1, P=0.02). No relationship was observed between ED use and depression (OR=1.6, 95% CI: 0.9-3.0, P=0.10) and anxiety (OR=0.8, 95% CI: 0.5-1.4, P=0.44), although those who were depressed with a suggestive but not statistically significant increased risk of acute ED use (OR=2.7, 95% CI: 1.0-7.4, P=0.06). CONCLUSIONS: The prevalence of ED consumption among middle school Italian students was high and it was associated with another risky behavior, smoking, but not with anxiety or depression. About half of ED consumers used alcohol mixed with ED.

Continuous wound infusion and local infiltration analgesia for postoperative pain and rehabilitation after total hip arthroplasty.

BACKGROUND: Total hip arthroplasty is one of the most common procedures in orthopedic surgery. We hypothesized that local infiltration of analgesia and continuous wound infusion of anesthetics in the first 72 hours after surgery could provide more effective postoperative analgesia with better rehabilitation. METHODS: A double-blind, randomized, controlled study was conducted with 96 patients who underwent total hip arthroplasty. The patients were randomized to receive either a local infiltration analgesia and continuous wound infusion of anesthetics or a local infiltration analgesia and continuous wound infusion of saline solution. The patients in both groups received subarachnoid anesthesia and a local infiltration analgesia. A multihole catheter was placed next to the implant and connected to an electronic pump containing a 300-mL solution of 0.2% levobupivacaine (experimental group) or saline (control group). RESULTS: A total of 96 consecutive patients were enrolled and randomized. Of these, 48 patients received local infiltration analgesia and continuous wound infusion of local anesthetics, and the remainder received local infiltration analgesia and continuous wound infusion of saline solution. The analysis showed a significant main effect of treatment on the postoperative incident of pain (Ftreat(1,93)=22.62, P=0.000) and on resting pain during the post-surgery follow-up (Ftreat(1,93)=15.62, P=0.0002). The pain scores during the rehabilitation period were significantly less in the experimental group. Analgesic consumption was less in the experimental group. CONCLUSIONS: The addition of continuous wound infusion of anesthetics to local infiltration analgesia provided an extended analgesic effect associated with good rehabilitation performance.

Selection Bias in Colorectal Surgery in a Non-Tertiary Hospital: Laparoscopic Versus Open Surgery.

INTRODUCTION: Laparoscopy is used increasingly to treat malignant and benign colorectal surgical diseases. However, this practice is still not offered to all patients. Many barriers halt the widespread use of laparoscopic colorectal surgery. Both surgeon's and patient's factors contribute to limit a wider use of laparoscopy in colorectal surgery. MATERIALS AND METHODS: We retrospectively analyzed 408 consecutive colorectal resections in a 4-year period, to find out if a selection bias exists in using laparotomy or laparoscopy for colorectal surgical diseases, and which factors are associated with a poor use of laparoscopy or to a preferred laparotomy. RESULTS: In our practice, advanced disease, American Society of Anesthesiologist class III and IV, and emergency status are all patient-related factors associated with laparotomy. Surgeon's age more than 52 years and lack of laparoscopic training are surgeon-related factors that negatively affect the chance of being operated on with the laparoscopic technique. CONCLUSIONS: An extensive laparoscopic colorectal training and a supporting environment, especially during the night shift, are needed to facilitate the use of laparoscopy in colorectal surgery avoiding a bias in selecting surgical candidates to one technique or another.

Office hysteroscopic-guided selective tubal chromopertubation: acceptability, feasibility and diagnostic accuracy of this new diagnostic non-invasive technique in infertile women.

The aim of this study was to evaluate accuracy, tolerability and side effects of office hysteroscopic-guided chromoperturbations in infertile women without anaesthesia. Forty-nine infertile women underwent the procedure to evaluate tubal patency and the uterine cavity. Women with unilateral or bilateral tubal stenosis at hysteroscopy with chromoperturbation, and women with bilateral tubal patency who did not conceive during the period of six months, underwent laparoscopy with chromoperturbation. The results obtained from hysteroscopy and laparoscopy in the assessment of tubal patency were compared. Sensitivity, specificity, accuracy, positive-predictive value and negative-predictive value were used to describe diagnostic performance. Pain and tolerance were assessed during procedure using a visual analogue scale (VAS). Side effects or late complications and pregnancy rate were also recorded three and six months after the procedure. The specificity was 87.8% (95% CI: 73.80-95.90), sensitivity was 85.7% (95% CI 57.20-98.20), positive and negative predictive values were 70.6% (95% CI: 44.00-89) and 94.7% (95% CI: 82.30-99.40), respectively. Pregnancy rate (PR) within six months after performance of hysteroscopy with chromoperturbation was 27%. Office hysteroscopy-guided selective chromoperturbation in infertile patients is a valid technique to evaluate tubal patency and uterine cavity.
