Clinical course of hypertrophic cardiomyopathy patients implanted with a transvenous or subcutaneous defibrillator. Europace 2023; 25:euad270. [PMID: 37724686 PMCID: PMC10507661 DOI: 10.1093/europace/euad270] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 08/09/2023] [Indexed: 09/21/2023] Open
Abstract
AIMS The implantable cardioverter-defibrillator (ICD) is a life-saving therapy in patients with hypertrophic cardiomyopathy (HCM) at risk of sudden cardiac death. Implantable cardioverter-defibrillator complications are of concern. The subcutaneous ICD (S-ICD) does not use transvenous leads and is expected to reduce complications. However, it does not provide bradycardia and anti-tachycardia pacing (ATP). The aim of this study was to compare appropriate and inappropriate ICD interventions, complications, disease-related adverse events and mortality between HCM patients implanted with a S- or transvenous (TV)-ICD. METHODS AND RESULTS Consecutive HCM patients implanted with a S- (n = 216) or TV-ICD (n = 211) were enrolled. Propensity-adjusted cumulative Kaplan-Meier curves and multivariate Cox proportional hazard ratios were used to compare 5-year event-free survival and the risk of events. The S-ICD patients had lower 5-year risk of appropriate (HR: 0.32; 95%CI: 0.15-0.65; P = 0.002) and inappropriate (HR: 0.44; 95%CI: 0.20-0.95; P = 0.038) ICD interventions, driven by a high incidence of ATP therapy in the TV-ICD group. The S- and TV-ICD patients experienced similar 5-year rate of device-related complications, albeit the risk of major lead-related complications was lower in S-ICD patients (HR: 0.17; 95%CI: 0.038-0.79; P = 0.023). The TV- and S-ICD patients displayed similar risk of disease-related complications (HR: 0.64; 95%CI: 0.27-1.52; P = 0.309) and mortality (HR: 0.74; 95%CI: 0.29-1.87; P = 0.521). CONCLUSION Hypertrophic cardiomyopathy patients implanted with a S-ICD had lower 5-year risk of appropriate and inappropriate ICD therapies as well as of major lead-related complications as compared to those implanted with a TV-ICD. Long-term comparative follow-up studies will clarify whether the lower incidence of major lead-related complications will translate into a morbidity or survival benefit.

Abstract
MID1 is an E3 ubiquitin ligase of the Tripartite Motif (TRIM) subfamily of RING-containing proteins, hence also known as TRIM18. MID1 is a microtubule-binding protein found in complex with the catalytic subunit of PP2A (PP2Ac) and its regulatory subunit alpha 4 (α4). To date, several substrates and interactors of MID1 have been described, providing evidence for the involvement of MID1 in a plethora of essential biological processes, especially during embryonic development. Mutations in the MID1 gene are responsible of the X-linked form of Opitz syndrome (XLOS), a multiple congenital disease characterised by defects in the development of midline structures during embryogenesis. Here, we review MID1-related physiological mechanisms as well as the pathological implication of the MID1 gene in XLOS and in other clinical conditions.

Abstract
BACKGROUND the purpose of this study is to compare the therapeutic effects of extracorporeal shock wave therapy (ESWT) to those of cryoultrasound (Cryo-US) therapy in chronic lateral epicondylitis during a 12-month period. METHODS single-blinded, randomized, controlled study of 80 participants treated for chronic LE with 3 ESWT sessions at 48/72-hours intervals (n=40) or 12 Cryo-US therapy sessions (4 sessions per week) (n=40). VAS and satisfactory results, considered as the sum of excellent and good scores in the Roles and Maudsley score, were used as outcome measures at baseline and 3, 6 and 12 months post-treatment. RESULTS the results show statistically significant differences in VAS between the two groups at 6 (p<0.001) and 12 months (p<0.001) in favour of the ESWT Group. At 12 months, a difference of more than 2 points in the VAS between the two groups is demonstrated in favour of the ESWT Group. Considering satisfactory results, significant differences between the two groups are observed at 6 (p=0.003) and 12 months (p <0.001) in favour of the ESWT Group where patients achieve a satisfactory rate over 50%. CONCLUSIONS ESWT has better clinical therapeutic results at 6- and 12-month follow-up as compared to Cryo-US therapy. LEVEL OF EVIDENCE 1B.

Evaluation of the efficacy of a haemostatic matrix for control of intraoperative and postoperative bleeding in major lung surgery: a prospective randomized study. Eur J Cardiothorac Surg 2014; 48:679-83. [PMID: 25543176 DOI: 10.1093/ejcts/ezu484] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2014] [Accepted: 11/25/2014] [Indexed: 11/12/2022] Open
Abstract
OBJECTIVES This prospective randomized study was designed to assess the safety and efficacy of a haemostatic matrix in intraoperative bleeding control and prevention of postoperative bleeding after major lung surgery. METHODS One hundred and twenty patients undergoing major lung resection and presenting with intraoperative persistent active bleeding have been prospectively enrolled and randomly assigned to receive [Floseal® group (FG)] or not (control group) the application of Floseal® to the bleeding site and to the site of the hilar dissection. To evaluate the efficacy of the product, several intraoperative and postoperative data were compared between the two groups. RESULTS No adverse event related to the haemostatic matrix application occurred. The intraoperative haemostasis rate at 3 (primary end-point), 6 and 10 min was significantly higher and the mean time to haemostasis was significantly shorter in the FG. The quantity of chest drain fluids did not show significant differences at 24, 48 and 72 h between the two groups. Postoperative haemoglobin-level variation was significantly lower in patients of the FG (-0.7 ± 0.66 vs -2.3 ± 5.87 g/dl; P = 0.04). Similarly, haematocrit variation was lower in the haemostatic group (-2.6 ± 2.19 vs -4.2 ± 3.71; P = 0.006). The chest drain duration resulted significantly shorter in the FG (10.3 ± 5.05 vs 13.3 ± 6.28 days; P = 0.005). In-hospital stay was shorter in the FG (6.4 ± 2.9 vs 8.1 ± 5.42 days; P = 0.044). CONCLUSIONS In conclusion, the application of Floseal® in major lung resections proved safe and effective in increasing the intraoperative successful haemostasis rate and in reducing postoperative variation in haemoglobin and haematocrit levels. The sealant use was also related with a significantly shorter chest drain duration and hospitalization.

Abstract
AIM Dysphonia and hearing loss are underestimated conditions in the elderly, despite their significant prevalence (18% and 50%, respectively) and their sociopsychological implications. Previous studies have shown that the reason for this lack of consideration is related to the general misconception of a simple age-related issue, as well as to the reduced communication requirements of this population, which can result in infrequent requests/supply of care. The purpose of the present study was to evaluate, within an elderly population, the subjective perception of hearing and voice dysfunctions, the resulting changes in communication skills, and the perception of handicap and disability. METHODS Four anonymous questionnaires were administered to 400 participants (218 men, 182 women) aged older than 65 years, some of whom (276) were hospitalized and some of whom (124) were outpatients. The questionnaires consisted of questions regarding age-related changes in voice, multiple-choice questions on the qualitative characteristics of the voice, questions regarding verbo-acoustic communication (hearing), the Voice Handicap Index, and the Self Assessment of Communication regarding the perception of hearing loss-related handicap and disability. Statistical correlations were calculated for voice dysfunction between the perception of disability and the clinical assessment of voice quality obtained by the Grade, Roughness, Breathiness, Asthenia, Strain scale, and between the perception of disability and the demand for care. RESULTS More than half of the elderly patients reported not perceiving voice changes throughout their lives. Most of the participants were satisfied with their own voices, although 65% of them judged them to be qualitatively altered, and in 31.5% of the participants, pathology was found on phoniatric evaluation. Low scores for vocal handicap (Voice Handicap Index) were found, and the type of perceived disability was mainly physical, although the association between Voice Handicap Index scores and Grade, Roughness, Breathiness, Asthenia, Strain was statistically significant. A total of 62% of the patients perceived hearing changes over their lifetimes not related to previous ear infections, but significantly correlated with a family history of hearing problems and with the need for specialist consultations. However, the perception of hearing loss handicaps and disability showed lower mean values, showing that older patients recognized dysfunction, but did not consider it to be a disability. CONCLUSIONS The present study showed that, despite the relevant incidence of hearing and voice disorders among the elderly population, the implications for communication abilities seems to be underestimated. Hence, it appears to be extremely important to undergo specialist screening consultations to detect eventual voice and hearing alterations, and to correct them with appropriate therapeutic strategies.

Abstract
The combination of a proton pump inhibitor and two antibiotics (clarithromycin plus amoxicillin or metronidazole) has been the recommended first-line therapy since the first guidelines for Helicobacter pylori (H. pylori) infection in children were published. In recent years, the success of eradication therapies has declined, in part due to the development of H. pylori resistant strains. Alternative anti-H. pylori treatments are currently becoming more popular than the traditional eradication methods. Components that may be used either as a monotherapy or, in combination with antimicrobials, resulting in a more effective anti-H. pylori therapy have been investigated in depth by several researchers. One of the potential therapies is probiotic cultures; promising results have been observed in initial studies with numerous probiotic strains. Nevertheless, many questions remain unanswered. In this article, we comprehensively review the possible mechanisms of action of probiotics on H. pylori infection, and present the results of published studies using probiotics as possible agents to control H. pylori infection in children. The effect of the addition of probiotics to the standard H. pylori eradication therapy for the prevention of antibiotic associated side-effects is also discussed.

The value of neurosurgical and intraoperative magnetic resonance imaging and diffusion tensor imaging tractography in clinically integrated neuroanatomy modules: a cross-sectional study. ANATOMICAL SCIENCES EDUCATION 2013; 6:294-306.

Abstract
Neuroanatomy is considered to be one of the most difficult anatomical subjects for students. To provide motivation and improve learning outcomes in this area, clinical cases and neurosurgical images from diffusion tensor imaging (DTI) tractographies produced using an intraoperative magnetic resonance imaging apparatus (MRI/DTI) were presented and discussed during integrated second-year neuroanatomy, neuroradiology, and neurosurgery lectures over the 2008-2011 period. Anonymous questionnaires, evaluated according to the Likert scale, demonstrated that students appreciated this teaching procedure. Academic performance (examination grades for neuroanatomy) of the students who attended all integrated lectures of neuroanatomy, was slightly though significantly higher compared to that of students who attended these lectures only occasionally or not at all (P=0.04). Significantly better results were obtained during the national progress test (focusing on morphology) by students who attended the MRI/DTI-assisted lectures, compared to those who did so only in part or not at all, compared to the average student participating in the national test. These results were obtained by students attending the second, third and, in particular, the fourth year (P≤0.0001) courses during the three academic years mentioned earlier. This integrated neuroanatomy model can positively direct students in the direction of their future professional careers without any extra expense to the university. In conclusion, interactive learning tools, such as lectures integrated with intraoperative MRI/DTI images, motivate students to study and enhance their neuroanatomy education.

Abstract
UNLABELLED A successful therapy needs high level of adherence consisting in right drug intake in terms of persistence and compliance. Our study suggests adherence is higher if spot (less than 30 days) therapies are excluded; the analysis of spot therapy causes underlines the importance of the interpersonal aspects of medical practice. INTRODUCTION A successful therapy needs a high level of adherence consisting in right drug intake in terms of persistence and compliance. The aim of this study was to evaluate anti-osteoporotic therapies recorded in general practitioner databases in the area of Rome, which used the same computerized medical record management. The study focused on evaluating therapy adherence, any adherence changes excluding spot therapies (less than 30 days), and any cause of early therapy discontinuation in a subgroup of patients randomly selected. METHODS Thirty-one databases were evaluated, including a total of 6,390 anti-osteoporotic therapies: 5,853 were prescribed to women and 537 to men. The prescribed drugs were: vitamin D (13 %), calcium (8.7 %), vitamin D + calcium (40.1 %), raloxifene (3.3 %), alendronate (16.4 %), risedronate (7.7 %), clodronate (10.4 %), or other drugs (0.4 %). Spot therapies represented 53.7 % of the total prescriptions. The difference between adherence in the total group (24.64 %) and the group excluding spot therapies (43.38 %) is significant. The main factors influencing low adherence were side effects (27 %), misinformation given by the physician (17 %), insufficient motivation (9 %), difficult intake (9 %), and no perceived benefits (9 %). RESULTS Our study suggests adherence is high and similar to other chronic diseases if spot therapies are excluded. The analysis of spot therapy causes suggests that an important role is played by the physician and the interpersonal aspects of medical practice, especially at the first prescriptions. CONCLUSIONS The physician should collaborate with patients in choosing a personalized medical treatment. Reducing spot therapy could be the real goal in order to improve anti-osteoporotic therapy adherence.

Abstract
BACKGROUND To assess the long-term patency of the biologic prosthetic conduit used for reconstruction of the superior vena cava (SVC) by magnetic resonance imaging (MRI). METHODS Patients undergoing oncologic resection and reconstruction of the SVC by a bovine pericardial prosthesis (January 2003 to April 2010) have been studied after 1 year (if surviving) by MRI for the assessment of the conduit long-term patency. Results were compared with those of a control group of patients with normal SVC. Blood flow and area of lumen section at 3 different levels (proximal, middle, distal) were analyzed. RESULTS Sixteen consecutive patients surviving after 1 year from surgery out of 17 (9 lung cancer, 8 mediastinal malignancy) undergoing SVC reconstruction were included. One patient died postoperatively and was not included. Sixteen patients with similar demographic characteristics were studied in the control group. Mean blood flow was 18.4±3.5 mL/sec (range 14.3 to 25.7) in patients with reconstructed SVC and 20.8±4.1 mL/sec (range 15.3 to 27.7) in the control group. Mean area of the conduit lumen section was 2.2±0.6 cm2 (range 1.6 to 3.6) at proximal level, 2.9±1.3 cm2 at middle level (range 1.3 to 5.7), and 2.1±0.9 cm2 (range 0.5 to 4) at distal level in the reconstructed group, and 2.6±0.7 cm2 (range 1.8 to 4.2), 2.7±0.7 cm2 (range 1.9 to 4.3), and 2.4±0.3 cm2 (range 1.8 to 3.1), respectively, at proximal, middle, and distal levels in the control group. Differences between the 2 groups were not significant (p>0.05). CONCLUSIONS The MRI assessment in terms of blood flow and area of lumen section at 3 different levels confirms that bovine pericardial conduit used for SVC replacement shows an optimal patency over the long term.

Abstract
BACKGROUND Tendinopathies represent a serious challenge for orthopaedic surgeons involved in treatment of athletes. PURPOSE To compare the effectiveness and safety of platelet-rich plasma (PRP) injections and focused extracorporeal shock wave therapy (ESWT) in athletes with jumper's knee. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS Forty-six consecutive athletes with jumper's knee were selected for this study and randomized into 2 treatment groups: 2 autologous PRP injections over 2 weeks under ultrasound guidance (PRP group; n = 23), and 3 sessions of focused extracorporeal shock wave therapy (2.400 impulses at 0.17-0.25 mJ/mm(2) per session) (ESWT group; n = 23). The outcome measures were Victorian Institute of Sports Assessment-Patella (VISA-P) questionnaire, pain visual analog scale (VAS), and modified Blazina scale. A reviewer who was blinded as to the group allocation of participants performed outcome assessments before treatment and at 2, 6, and 12 months after treatment. Nonparametric tests were used for within-group (Friedman/Wilcoxon test) and between-group (Kruskal-Wallis/Fisher test) testing, and the significance level was set at .05. RESULTS The 2 groups were homogeneous in terms of age, sex, level of sports participation, and pretreatment clinical status. Patients in both groups showed statistically significant improvement of symptoms at all follow-up assessments. The VISA-P, VAS, and modified Blazina scale scores showed no significant differences between groups at 2-month follow-up (P = .635, .360, and .339, respectively). The PRP group showed significantly better improvement than the ESWT group in VISA-P, VAS scores at 6- and 12-month follow-up, and modified Blazina scale score at 12-month follow-up (P < .05 for all). CONCLUSION Therapeutic injections of PRP lead to better midterm clinical results compared with focused ESWT in the treatment of jumper's knee in athletes.

Abstract
Liver resection is considered the therapeutic gold standard for primary and metastatic liver neoplasms. The reduction of postoperative complications and mortality has resulted in a more aggressive approach to hepatic malignancies. For the most part, results of liver surgery have been published by highly experienced institutions, but the observations of highly specialized units results may not reflect the current status of hepatic surgery, underestimating mortality and complications. The objective of this study is to evaluate morbidity and mortality as a result of liver resection for primary and metastatic lesions, analyzing a large number of studies with a meta-analytic process taking into account the overdispersion of data. An extensive literature search has been conducted, and 148 papers published between January 2000 and April 2008, including a total of 36,629 patients from both high-volume and low volume institutions, were included in the meta-analysis. A beta binomial model was used to provide a robust estimate of the summary event rate by pooling overdispersion binomial data from different studies. Overall morbidity and mortality after liver surgery were 29.32 per cent and 3.15 per cent, respectively. Significantly higher postoperative mortality was observed after liver resection for hepatocellular carcinomas and primary hepatic tumors. The application of a beta binomial model to correct for overdispersion of liver surgery data showed significantly higher postoperative mortality rates in patients with hepatocellular carcinomas or primary hepatic tumors after liver resection.

We present results of a study of the decay J/ψ → ωηπ+ π- using a sample of (225.2 ± 2.8) × 10(6) J/ψ events collected by the BESIII detector, and report the observation of a new process J/ψ → ωX(1870) with a statistical significance of 7.2σ, in which X(1870) decays to a(0)(±)(980)π±. Fitting to ηπ+ π- mass spectrum yields a mass M = 1877.3 ± 6.3(stat)(-7.4)(+3.4)(syst) MeV/c(2), a width Γ = 57 ± 12(stat)(-4)(+19)(syst) MeV/c(2), and a product branching fraction B(J/ψ → ωX) × B(X→a(0)(±)(980)π±) × B(a(0) (±)(980) → ηπ±) = [1.50 ± 0.26(stat)(-0.36)(+0.72) (syst)] × 10(-4). Signals for J/ψ → ωf(1)(1285) and J/ψ → ω η(1405) are also clearly observed and measured.

Abstract
Using (106±4)×10⁻⁶ ψ(3686) events accumulated with the BESIII detector at the BEPCII e⁺e⁻ collider, we present the first measurement of decays of χ(c1) to vector meson pairs φφ, ωω, and ωφ. The branching fractions are measured to be (4.4±0.3±0.5)×10⁻⁴, (6.0±0.3±0.7)×10⁻⁴, and (2.2±0.6±0.2)×10⁻⁵, for χ(c1)→φφ, ωω, and ωφ, respectively, which indicates that the hadron helicity selection rule is significantly violated in χ(cJ) decays. In addition, the measurement of χ(cJ)→ωφ provides the first indication of the rate of doubly OZI-suppressed χ(cJ) decay. Finally, we present improved measurements for the branching fractions of χ(c0) and χ(c2) to vector meson pairs.

Confirmation of the X(1835) and observation of the resonances X(2120) and X(2370) in J/ψ→γπ+π-η'. PHYSICAL REVIEW LETTERS 2011; 106:072002.

Abstract
With a sample of (225.2±2.8)×10(6) J/ψ events registered in the BESIII detector, J/ψ→γπ(+)π(-)η(') is studied using two η(') decay modes: η(')→π(+)π(-)η and η(')→γρ(0). The X(1835), which was previously observed by BESII, is confirmed with a statistical significance that is larger than 20σ. In addition, in the π(+)π(-)η(') invariant-mass spectrum, the X(2120) and the X(2370), are observed with statistical significances larger than 7.2σ and 6.4σ, respectively. For the X(1835), the angular distribution of the radiative photon is consistent with expectations for a pseudoscalar.

Abstract
The decays ψ'→γπ(0), γη and γη' are studied using data collected with the BESIII detector at the BEPCII e(+)e(-) collider. The processes ψ'→γπ(0) and ψ'→γη are observed for the first time with signal significances of 4.6σ and 4.3σ, respectively. The branching fractions are determined to be B(ψ'→γπ(0))=(1.58±0.40±0.13)×10(-6), B(ψ'→γη)=(1.38±0.48±0.09)×10(-6), and B(ψ'→γη')=(126±3±8)×10(-6), where the first errors are statistical and the second ones systematic.

Procutase versus 1% silver sulphadiazine in the treatment of minor burns. Burns 2010; 36:871-5. [PMID: 20079572 DOI: 10.1016/j.burns.2009.10.021] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2008] [Revised: 10/22/2009] [Accepted: 10/26/2009] [Indexed: 11/30/2022]
Abstract
The purpose of this randomised comparative study was to evaluate the use of silver sulphadiazine (SSD) 1% cream (Group A) with the use of Procutase (Group B) in treating burns with a TBSA <10% and a depth not greater than 2nd degree burns and thus suitable for outpatient management. The two groups were similar in age, gender, race, and extent of burn. Procutase is an ionic hydrogel composed of natural hydrophilic polymers in an active ionic solution with an inhibitor of matrix metalloproteinases MMP-1, -3 and -9 (collagenase/gelatinase). Subjects were seen in follow-up biweekly, and wounds of patients in SSD group were compared with those of Procutase group for healing time, pain score at dressing change, compliance with therapy and complication rate. The result of this study showed that Procutase treated patients had statistically significantly less pain and shorter wound healing time. Procutase can be used successfully in patients with burns that do not require hospital admission.

Abstract
UNLABELLED The aim of the present study waw to assess efficacy and safety of radio-immunotherapy with Zevalin (RIT-Z) in heavily pre-treated, rituximab-refractory patients. PATIENTS AND METHODS We studied 12 patients with indolent lymphoma and 7 with aggressive lymphoma. The median number of prior rituximab-containing treatments was 2; overall, 3 therapies had been previously given. Ten patients received RIT-Z as salvage therapy, 9 at high risk of relapse received RIT-Z as consolidation. Staging and follow-up were obtained by positron-emission tomography. Outcomes assessed were failure-free survival (FFS) and time to next treatment (TTNT). RESULTS Overall FFS and TTNT were 5 and 11 months, respectively; median follow-up 13 months. Major findings were i) no long-term remissions observed in 7 patients who had not responded to their most recent therapy and ii) lack of association between any pre-therapy variables analysed and outcomes. Different subgroups showed no difference in terms of toxicity. CONCLUSION We encourage the use of RIT-Z as a consolidation for pre-treated patients with both indolent and aggressive lymphoma.

Inverse correlation between morning plasma cortisol levels and MMPI psychasthenia and depression scale scores in victims of mobbing with adjustment disorders. NEURO ENDOCRINOLOGY LETTERS 2007; 28:610-613.

Abstract
OBJECTIVES Evidence in the literature suggests stress-related changes of hypothalamus-pituitary-adrenal (HPA) axis in mobbing. We investigated the association between HPA activity and psychological profiles in mobbing, using a multidisciplinary approach. DESIGN Forty-eight victims of mobbing were evaluated by a working group of the Departments of Occupational Medicine, Psychiatry and Internal Medicine. After an informed consent, a detailed occupational history, a psychiatric interview with Minnesota Multiphasic Personality Inventory 2 (MMPI-2) administration and a blood sample (8:00 AM) for the determination of basal adrenocorticotropin (ACTH), cortisol and dehydroepiandrosterone sulphate (DHEAS) plasma levels were collected. Twenty-six patients received an overnight dexamethasone (dex) test. RESULTS Mean ACTH, cortisol and DHEAS levels were within normal ranges. The dex-test response was normal, with a significant hormone suppression (ACTH p<0.001, cortisol p<0.001, DHEAS p<0.001). The correlations between basal hormones and the psychometric scales of MMPI-2 revealed that cortisol was significantly and negatively related to Psychasthenia (Pt, p=0.003) and Depression (D, p=0.006), while DHEAS showed a significant negative correlation to Hysteria (Hy, p=0.008). Basal ACTH levels were not significantly related to psychometric scales. CONCLUSION A significant inverse correlation between morning plasma cortisol levels and psychometric parameters in victims of mobbing with adjustment disorders was observed. A larger group of patients is necessary to identify and validate a cut-off cortisol level that may become an innovative biological parameter for the diagnosis and follow-up in victims of mobbing.

Do hypertension and diabetes mellitus influence the site of atherosclerotic plaques? LA CLINICA TERAPEUTICA 2006; 157:9-13.

Abstract
BACKGROUND The concomitant occurrence of atherosclerotic plaques in carotid, coronary and peripheral vessels has been described in a number of studies. A few studies were, on the contrary, done for determining the role of hypertension and/or type 2 diabetes mellitus for the occurrence of the atherosclerotic plaques in different anatomical sites. Moreover these studies deal with atherosclerotic lesions that are generally considered, without differentiating their morphology as a function of the underlying disease, territory, and risk factors. Primary aim of this study is, thus, to verify whether the two most common causes for atherosclerotic disease, i.e., hypertension and type 2 diabetes mellitus, may influence the site of appearance of the atherosclerotic plaque. A second aim is to verify if the anatomical site of the plaque influences plaque morphology and vulnerability. PATIENTS AND METHODS A retrospective study of 244 patients affected with type 2 diabetes mellitus or hypertension was performed; 114 subjects were affected by moderate-severe and drugs-treated hypertension (Group A); 55 were affected by type 2 diabetes mellitus in treatment with oral antidiabetic drugs (Group B); 75 were diagnosed as affected by the association hypertension and diabetes (Group C). The inclusion criteria were: exhaustive images of the cardiovascular system (coronary angiography, colour Doppler ultrasound of lower limb arteries and carotid arteries, transthoracic Doppler echocardiography ) and a serum lipid profile (total serum cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides). Three different anatomical sites: carotid axis, ilio-femoral arteries and coronary district, were considered. In each site a plaque lesion-classification was performed to describe the morphology of the plaque. RESULTS In patients with hypertension, carotid district seems to be the preferential site of onset of atherosclerotic plaques even if a statistical significant association between the two conditions was not found. Statistical evaluation didn't show significant association between different risk factors and coronary district too. On the opposite, a significant association (p < 0.001) between diabetes and the presence of atherosclerotic plaques into lower limb district was found. A very significant association (p < 0.001) between type 2-diabetes and the presence of non-ulcerative plaques was found too. CONCLUSIONS Our study underlines the relationship between vessel plaques localization and concomitant risk factors for atherosclerosis and suggests a possible difference in plaque morphology and biological behaviour related to different anatomical site.

Abstract
The typical US pattern of obstructive atelectasis consists in a triangular hypoechoic area with anechoic bands inside related to fluid-filled bronchial structures--the US fluid bronchogram sign. According to some authors, this US sign within a chest mass indicates pulmonary parenchyma disease. Furthermore, it suggests the diagnosis of lung collapse. Sixty-one patients with obstructive atelectasis confirmed with conventional radiography, conventional and computed tomography, and bronchoscopy were submitted to B-mode and color-Doppler US to assess the importance of the US fluid bronchogram sign in obstructive pulmonary atelectasis. In this condition, B-mode US showed tubular anechoic bands in 59/61 patients. Power Doppler venous sampling showed a Doppler spectrum with marked phase oscillations. Arterial sampling showed a Doppler spectrum with high distal impedance-with poor or totally absent diastolic component. To conclude, in the atelectasis area, B-mode US showed in 96% of patients some anechoic bands with no apparent pulsatility. Color-Doppler showed color flow in 100% of cases, which confirmed the vascular nature of the masses. Thus, the US fluid bronchogram, which is frequently described in the literature, was never observed in our series. Power Doppler spectral flow analysis can be useful in the diagnosis of obstructive atelectasis because it depicts the hemodynamics of atelectasis parenchyma. Indeed, the arterial spectrum with high distal resistance is consistent with the effects of hypoxia on intra-atelectatic blood vessels. Further research is necessary to assess the role of color-Doppler US in the hemodynamic study of intra-atelectatic vessels. However, our preliminary results open new perspectives for the acquisition of physiopathologic data on abnormal blood flow in obstructive atelectasis.
