Knowledge and attitudes on influenza vaccination among Italian physicians specialized in respiratory infections: an Italian Respiratory Society (SIP/IRS) web-based survey.

INTRODUCTION: Influenza epidemics are one of the main causes of morbidity and mortality worldwide. Influenza vaccination is considered the most important public health intervention to prevent seasonal influenza infection. European health authority policies focus on patient protection by vaccinating both these subjects and their care-givers, including health-care workers (HCWs). The aim of this survey is to investigate knowledge about influenza vaccination and intention to get vaccinated among Italian HCWs who take care patients with respiratory disease. METHODS: An anonymous web-based survey was addressed to members of the Italian Respiratory Society (IRS). RESULTS: Among the 1,776 IRS members who have been invited to the survey, 144 (8.1%) completed the survey (97 men; median age 59 years; 85.4% Respiratory Disease). The vast majority recommended vaccination to all their patients (81%). More than two thirds of respondents considered influenza vaccination safe for immunocompromised patients. More than 50% of respondents underwent seasonal influenza vaccination in 2015 and 68% declared the intention to undergo vaccination in 2016 epidemic season. Reasons for having vaccination mainly referred to 'protect oneself from influenza' (63%), 'protect patients' (31%) or household members' (6%). The main reasons for vaccination refusal were 'lack of time' (45%), 'concerns about side effects' (22%), 'do not get influenza easily and/or not afraid of influenza infection' (22%) and 'disagreement with indication of vaccination for HCWs' (9%). CONCLUSIONS: The promotion of better knowledge and attitude towards influenza vaccination among Italian specialists remains an unmet goal and should be addressed by appropriate multifaceted interventions.

Immunomodulatory effects of pidotimod in adults with community-acquired pneumonia undergoing standard antibiotic therapy.

The morbidity and mortality of community-acquired pneumonia (CAP) are still elevated and two aspects seem to contribute to a worse outcome: an uncontrolled inflammatory reaction and an inadequate immune response. Adjuvants, including corticosteroids and intravenous immunoglobulins, have been proposed to counterbalance these effects but their efficacy is only partial. We examined the immunomodulatory activity of Pidotimod (PDT), a synthetic dipeptide molecule in adult patients hospitalized for CAP. Sixteen patients with a diagnosis of CAP and a PSI score III or IV and/or a CURB-65 0-2 were randomized to receive either levofloxacin 500 mg b.i.d. alone or levofloxacin plus PDT (800mg, 2 daily doses). Blood samples were drawn at baseline (T0), before initiation of therapy, as well as 3 (T3), and 5 (T5) days after initiation of therapy. Immunologic and clinical parameters were analyzed at each time point. Supplementation of antibiotic therapy with PDT resulted in an upregulation of antimicrobial and of immunomodulatory proteins as well as in an increased percentage of Toll like receptor (TLR)2- and TLR4, and of CD80- and CD86-expressing immune cells. Notably, Pidotimod supplementation was also associated with a robust reduction of TNFα-producing immune cells. No significant differences were observed in clinical parameters. These results confirm that supplementation of antibiotic therapy with Pidotimod in patients with CAP results in a potentially beneficial modulation of innate immunity.

The role of vaccination in preventing pneumococcal disease in adults.

Pneumococcal infections, including pneumonia and invasive disease, are major sources of morbidity and mortality worldwide. Prevention of the first acquisition of Streptococcus pneumoniae through the use of vaccines represents an effective method to reduce the burden of the disease in both children and adults. Two vaccines are currently available in adults: a pneumococcal polysaccharide vaccine (PPV23) that includes 23 purified capsular polysaccharide antigens and a pneumococcal protein-conjugate vaccine (PCV13) that includes capsular polysaccharide antigens covalently linked to a non-toxic protein. The PPV23 induces a humoral immune response and since it has been licensed has been the subject of debates and controversies. Numerous studies and meta-analyses have shown that PPV23 protects against invasive pneumococcal disease, although there are conflicting data regarding its efficacy for the prevention of pneumonia. Vaccination with PCV13 stimulates good antibody responses as well as mucosal immunity and suppresses colonization. A conjugate vaccine can be expected to have benefits over a polysaccharide vaccine because of the characteristics of a T-cell-dependent response in terms of affinity, maturation of antibodies with repeated exposure, induction of immunological memory and long-lasting immunity. PCV13 has demonstrated all of these characteristics in children and fundamental differences in adults are not expected. The efficacy in adults is currently being investigated and results will be available soon.

Compliance with anti-H1N1 vaccine among healthcare workers and general population.

Population protection through vaccination against infectious diseases has been one of the major achievements of public health care. The recent H1N1 influenza virus pandemic reopened the discussion on the strategic arrangements for vaccination in the face of spreading infection. Even though vaccination against a pandemic strain is considered to be one of the most effective countermeasures for protecting individuals, the general acceptance of H1N1 influenza vaccination has been low worldwide. The understanding of the potential health risks of the novel influenza A (H1N1) strain, the distrust of vaccinations and concerns about vaccine safety are the main reasons reported by the public for not undergoing vaccination. Concern about vaccine safety and distrust of health authorities are the commonest reasons given for low compliance with vaccination by healthcare workers. Better communication strategies to improve vaccination acceptance by the general population and by healthcare workers are required.

Understanding the burden of pneumococcal disease in adults.

Streptococcus pneumoniae causes different types of acute, invasive and non-invasive clinical infections, being the most frequently detected pathogen responsible for community-acquired pneumonia. Pneumococcal pneumonia is accompanied by bacteraemia in 10-30% of cases. Streptococcus pneumoniae is gaining resistance to the in vitro activity of several antimicrobial agents and, even if questions remain regarding the clinical impact of this phenomenon, more and more reports indicate that antibiotic resistance can lead to more treatment failures if not higher mortality. Use of the 23-valent anti-pneumococcal vaccine appears to offer subpotimal protection against pneumococcal disease, particularly among high-risk adult populations. Vaccination against S. pneumoniae with new conjugate vaccines seems to be the most promising field for real improvement in the management of pneumococcal infections in adults.

When is a technically successful peripheral angioplasty effective in preventing above-the-ankle amputation in diabetic patients with critical limb ischaemia?

AIM: To determine parameters predictive of avoidance of major (above-the-ankle) amputation after a technically successful peripheral angioplasty (PTA) in patients with diabetes with critical limb ischaemia. METHODS: From January 1999 to December 2003, 420 consecutive patients with diabetes admitted to hospital because of critical limb ischaemia underwent peripheral angiography and concomitant technically successful PTA. Transcutaneous oxygen tension (TcPO(2)) was measured before and after PTA. Major amputation at 30 days was recorded. RESULTS: After PTA, the iliac-femoral-popliteal axis was patent in all patients. In 67 patients, all three crural arteries were patent, in 143 patients 2 crural arteries were patent, and in 186 patients one crural artery was patent (104 peroneal, 62 anterior tibial, 20 posterior tibial). In 24 patients, all three crural arteries were occluded. Twenty-two major amputations were performed. Of these, 15 were performed in the 24 patients with occlusion of all the infrapopliteal arteries. Seven of the 186 patients in whom only the peroneal artery was patent required amputation. In patients not requiring amputation, TcPO(2) increased from 15.5 +/- 11.9 to 45.0 +/- 12.0 mmHg (P = 0.000), while in those requiring amputation, TcPO(2) increased from 9.6 +/- 7.7 to 18.6 +/- 8.1 mmHg (P < 0.082). Multivariate analysis indicated an independent role of occlusion of infrapopliteal arteries after PTA (OR 8.20 for every crural obstructed artery, P = 0.022, CI 1.35-49.6) and TcPO(2) after PTA (OR 0.80 for increase of 1 mmHg, P < 0.001, CI 0.74-0.88). CONCLUSIONS: In patients with diabetes, PTA is effective in avoiding major amputation, provided recanalization occurs in at least one tibial artery down to the foot. In a few patients, re-canalization of the peroneal artery alone is not sufficient to avoid major amputation.

Early and five-year amputation and survival rate of diabetic patients with critical limb ischemia: data of a cohort study of 564 patients.

OBJECTIVE: To evaluate the early and late major amputation and survival rates and related risk factors in diabetic patients with critical limb ischemia (CLI). DESIGN: Retrospective study. METHODS: Revascularization feasibility, major amputation, survival rate and related risk factors were recorded in 564 diabetic patients consecutively hospitalized for CLI from 1999 to 2003 and followed until June 2005. RESULTS: Peripheral angioplasty (PTA) was carried out in 420 (74.5%), bypass graft (BPG) in 117 (20.7%) patients. In 27 (4.8%) patients both PTA and BPG were not possible. Twenty-three above-the-ankle amputations (4.1%) were performed at 30 days: 6 in PTA patients, 3 in BPG patients, 14 in non revascularized patients. In the follow-up of 558 patients (98.9%), 62 repeated PTAs and 9 new BPGs, 32 new major amputations (16 in PTA patients, 14 in BPG patients and 2 in non-revascularized patients) were performed. Major amputation was associated with absence of revascularization (OR 35.9, p < 0.001, CI 12.9-99.7), occlusion of each of the three crural arteries (OR 8.20, p = 0.022, CI 1.35-49.6), wound infection (OR 2.1, p = 0.004 CI 1.3-3.6), dialysis (OR 4.7, p = 0.001 CI 1.9-11.7) increase in TcPO2 after revascularization (OR 0.80, p < 0.001 CI 0.74-0.87). One hundred seventy three patients died during follow-up and this was associated with age (HR 1.05, p < 0.001 CI 1.03-1.07), history of cardiac disease (HR 2.16, p < 0.001 CI 1.53-3.06), dialysis (HR 3.52, p < 0.001 CI 2.08-5.97), absence of revascularization (HR 1.68, p < 0.001, CI 1.29-2.19) and impaired ejection fraction (HR 1.08, p < 0.001, CI 1.05-1.09). CONCLUSIONS: In diabetic patients with CLI the revascularization is feasible in most cases and allows a low rate of early major amputation. This rate is higher in the follow-up period. Major amputation is very high in patients where revascularization is not feasible while the high mortality rate is due to the serious comorbidities observed in these patients.

Peripheral angioplasty as the first-choice revascularization procedure in diabetic patients with critical limb ischemia: prospective study of 993 consecutive patients hospitalized and followed between 1999 and 2003.

OBJECTIVE: To evaluate the effectiveness of peripheral angioplasty (PTA) as the first-choice revascularisation procedure in diabetic patients with critical limb ischemia (CLI). DESIGN: Prospective study. METHODS: PTA was employed as first choice revascularisation in a consecutive series of diabetic patients hospitalized for CLI between January 1999 and December 2003. RESULTS: PTA was successful performed in 993 patients. Seventeen (1.7%) major amputations were carried out. One death and 33 non-fatal complications were observed. Mean follow-up was 26+/-15 months. Clinical restenosis was observed in 87 patients. The 5 years primary patency was 88%, 95% CI 86-91%. During follow-up 119 (12.0%) patients died at a rate of 6.7% per year. CONCLUSIONS: PTA as the first choice revascularisation procedure is feasible, safe and effective for limb salvage in a high percentage of diabetic patients. Clinical restenosis was an infrequent event and PTA could successfully be repeated in most cases.

Extensive use of peripheral angioplasty, particularly infrapopliteal, in the treatment of ischaemic diabetic foot ulcers: clinical results of a multicentric study of 221 consecutive diabetic subjects.

OBJECTIVE: To evaluate the feasibility, technical effectiveness and limb salvage potential of percutaneous transluminal angioplasty (PTA), particularly infrapopliteal, in diabetic subjects with ischaemic foot ulcer. DESIGN: Intervention study with PTA in consecutive series. SETTING: Six Diabetology Foot Centres and one Cardiovascular Catheterization Laboratory in Italy. SUBJECTS: Two hundred and twenty-one consecutive diabetic subjects hospitalized for ischaemic foot ulcer. INTERVENTION: Peripheral arterial occlusive disease (PAOD) was investigated by means of foot pulses assessment, ankle-brachial-index (ABI), transcutaneous oxygen tension (TcPO2) and duplex scanning. If non-invasive parameters suggested PAOD, angiography was performed and a PTA was carried out during the same session. MAIN OUTCOME MEASURES: PTA feasibility, improvement of ABI and TcPO2, limb salvage rate, clinical recurrence. RESULTS: On angiography, two patients had stenoses which were <50% of the vessel diameter. PTA was performed in 191 (85.3%) of the 219 subjects with stenoses >50%, even when longer than 10 cm and/or multiple/calcified. In 11 patients (5.8%) PTA was performed in the proximal axis exclusively, in 81 (42.4%) patients in the infrapopliteal axis exclusively and in 99 (51.8%) in both the femoropopliteal and infrapopliteal axis. Both ABI and TcPO2 improved significantly after PTA (P < 0.0001). Clinical recurrence occurred in 14 subjects: 10 of whom underwent a second successful PTA. Of the 191 patients who underwent PTA, 10 (5.2%) underwent an above-the-ankle amputation. CONCLUSIONS: PTA, including infrapopliteal, is feasible in most diabetic subjects with ischaemic foot ulcer and is effective for foot revascularization. Clinical recurrence was infrequent and the procedure could successfully be repeated in most cases. In subjects treated successfully with PTA the above-the-ankle amputation rate was low. PTA should be considered as the revascularization treatment of first choice in all diabetic subjects with foot ulcer and PAOD.

A single blind comparison of amisulpride, fluoxetine and clomipramine in the treatment of restricting anorectics.

1. The study evaluated the efficacy of amisulpride, fluoxetine and clomipramine at the beginning of the re-feeding phase of the treatment of restricting anorexia nervosa according to DSM-IV criteria. 2. 13 patients, mean weight 37.61 kg +/- 9.80 SD, were treated with clomipramine at a mean dosage of 57.69 mg +/- 25.79 SD; 10 patients, mean weight 40.90 kg +/- 6.98 SD, were treated with fluoxetine at a mean dosage of 28.00 mg +/- 10.32 SD; 12 patients, mean weight 38.41 kg +/- 8.33 SD, were treated with amisulpride at a mean dosage of 50.00 mg +/- 0.00 SD. 3. Clinical evaluation was carried out under single-blind condition at basal time and after three months by a structured clinical interview, the Eating Disorder Interview based on Long Interval Follow-up Evaluation (LIFE II BEI). 4. Patients treated with amisulpride showed a more significant increase (p=0.016) of mean weight. Concerning weight phobia, body image disturbance and amenorrhoea, no significant difference resulted.

Effectiveness and safety of a nonremovable fiberglass off-bearing cast versus a therapeutic shoe in the treatment of neuropathic foot ulcers: a randomized study.

OBJECTIVE: To evaluate and compare the rate of reduction of the surface area of neuropathic plantar ulcers in diabetic patients treated with nonremovable rigidity-differentiated fiberglass off-bearing casts or a cloth shoe with a rigid sole with unloading alkaform insoles. The secondary aim was to evaluate the side effects and degree of patient acceptance of treatment. RESEARCH DESIGN AND METHODS: Fifty diabetic patients with neuropathic plantar ulcers were consecutively enrolled and randomized to one of two treatment groups. Of the 50 patients, 24 were treated with a specialized cloth shoe with a rigid sole and an unloading alkaform insole (shoe group), and 26 patients were treated with a nonremovable off-bearing fiberglass cast (cast group). All patients in both study groups returned to the clinic for weekly control visits. Their ulcers were treated with a standard dressing. Tracings of the ulcer area using a transparent dressing were performed on the day of entry to the study and after 30 days of treatment. The presence of new ulcerations caused by the use of the pressure-relief apparatus was recorded. Patient acceptance of the treatment was measured using a visual analog scale. RESULTS: At the end of the treatment period, an 8.3% increase of the ulcer area was observed in two patients in the shoe group, whereas in the cast group, no patient presented an increase. The reduction of the ulcer area was statistically more rapid in the cast group (Mann-Whitney test, P = 0.0004). Furthermore, the number of ulcers completely healed at the 30-day time point was 13 (50%) in the cast group and 5 (20.8%) in the shoe group (P = 0.03). In both groups, no side effects were recorded. The average score +/- SD of patient acceptance was 91.15 +/- 9.9 in the shoe group and 88.33 +/- 17.3 (NS) in the cast group. CONCLUSIONS: Our study has shown a significant difference in the speed of the reduction of neuropathic plantar ulcers treated with a fiberglass cast compared with a specialized cloth shoe. The use of fiberglass material with variable rigidity has also shown two important results: the elimination of side effects including ulcers caused by the cast, and high patient acceptance. These data show that the use of off-bearing casts made with fiberglass bandages of variable rigidity is the elective treatment of neuropathic plantar ulcers.

Eating Attitudes Test and culture: a study in northern and southern Italy.

The EAT (Eating Attitudes Test) has been widely used to compare eating morbidity in cultural groups and variations in it have been taken as indicative of cultural differences. This study assumed the existence of cultural differences between the north and the south of Italy. The EAT scores of female students from a northern and a southern Italian high school were compared. They were both higher than in other European studies, though there were no significant differences between the two groups. The result could be due to sampling limitations, but could also indicate that the EAT is not a reliable yardstick of cultural differences.

Psychiatric symptoms do not correlate with cognitive decline, motor symptoms, or CAG repeat length in Huntington's disease.

OBJECTIVES: To investigate the hypothesis that psychiatric disturbances in Huntington's disease are related to degree of cognitive or motor compromise and to determine correlations between CAG repeat length within the gene for Huntington's disease and disease severity. DESIGN: Consecutive series of patients with Huntington's disease. SETTING: Neurological specialty hospital. PATIENTS: Seventeen men and 12 women from 24 families. MAIN OUTCOME MEASURES: The Hamilton Psychiatric and Anxiety Rating Scales and Brief Psychiatric Rating Scale were used to assess psychiatric disturbances; Folstein's Quantified Neurological Examination to evaluate motor status; and the Mini-Mental State Examination, Raven Progressive Matrices), Phonemic Verbal Fluency Test, Short Tale Test, Visual Search Test, and Benton's Visual Orientation Line Test to evaluate cognitive function. The length of the CAG repeat sequence in the Huntington's gene was determined by quantitative polymerase chain reaction. RESULTS: Cognitive test scores correlated significantly with each other; of these, results of the Visual Search and Short Tale tests correlated significantly with the Folstein's Quantified Neurological Examination score (P = .05 and P = .03, respectively). Results of the Folstein's Quantified Neurological Examination also correlated with the illness duration and the length of the CAG repeat. Although psychiatric scores correlated significantly among themselves (P < .01), neither cognitive compromise, motor deterioration, nor CAG length were related to the extent of psychiatric compromise. Patients who were depressed when they were examined tended to have a history of psychiatric disorders. CONCLUSIONS: The lack of correlation between disease severity and psychiatric disturbances indicates that psychiatric disorders progress nonlinearly, possibly because of differential degeneration of the striatal-cortical circuits; the possibility that psychiatric disorders are prevalent in certain families with a member who has Huntington's disease is being further investigated. The lack of correlation between CAG length and cognitive and psychiatric variables needs further investigation.

Neurobiological and psychopharmacological basis in the therapy of bulimia and anorexia.

1. Eating disorders can be found in several psychiatric pathologies: schizophrenia, delusional disorder (somatic type), bipolar disorders, major depressive disorder, borderline personality disorder, generalized anxiety disorder, body dysmorphic disorder, somatization disorder and conversion disorder. 2. Although their clinical features have been defined, relatively little is known about the role of neurobiological patterns in the pathogenesis of these disorders. Several CNS neurotransmitters and neuromodulators are involved in the regulation of eating behavior in animals and have been implicated in symptoms such as depression and anxiety often observed in patients with eating disorders. The authors will review some studies on NA, DA, 5-HT, beta-endorphins, CRH, VP, OT, CCK, NPY and PYY involved in eating disorders. Furthermore, we will highlight some of the studies on drug therapy of eating disorders taking into account the effects of these agents on neurotransmitters and neuromodulators. 3. Antidepressant drugs have long been used for anorexia nervosa and bulimia, these disorders been claimed to be affective equivalent. Antidepressant agents seem to be effective in reducing the frequency of binge-eating episodes, purging behavior and depressive symptomatology. It is notable that antidepressant agents have been proved to be effective in patients with chronic bulimic symptoms, even in cases persisting for many years and in patients who had repeatedly failed courses of alternative therapeutic approaches. In all of the positive studies, antidepressant agents appeared effective even in bulimic subjects who did not display concomitant depression. 4. Few controlled studies on use of medications for anorexia nervosa have been published. Central serotonergic receptor-blocking compounds such as cyproheptadine cause marked increase in appetite and body weight. Zinc supplementation or cisapride could be a therapeutic option in addition to psychological and other approaches in anorexia nervosa. 5. There is no therapy as yet which is fully effective in alimentary disorders. Psychotropic drugs give some relief from symptoms, but they cannot cure the disorders. An integrated approach, either pharmacological or psychological, is still recommendable.

Maternal uniparental disomy for chromosome 14.

A girl carrying a de novo balanced 13-14 robertsonian translocation showed a clinical phenotype with severe hypotonia, hyperextensible joints, frontal bossing, asymmetric face, no mental retardation, severe scoliosis and motor delay. In situ hybridization analysis on chromosome spreads revealed the presence of the two centromeres in the rearranged chromosomes. Molecular analysis on genomic DNA showed the presence in the proposita of two chromosomes 14 of maternal origin and no chromosome 14 from the father indicating a maternal monocentric uniparental disomy for chromosome 14 (mUPD14). Our patient shows several similarities with other reported cases of mUPD14, suggesting imprinting of a region(s) of chromosome 14 and defining a possible mUPD14 Syndrome.

[Paratesticular rhabdomyosarcoma]. / Rabdomiosarcoma paratesticular.

Report of one paratesticular RMS in a 28 year-old male. The paper includes a review of the various clinical, etiopathogenic and therapeutic features involved. RMS is a neoplasia difficult to diagnose through M.O. and, quite often, it is necessary to use immunohistochemical techniques in order to discover some of the muscular fibre markers, such as Desmin, Myosin and Myoglobin. Several theories have been put forward to explain its origin, and the most widely accepted defends an origin in a poorly differentiated mesenchymal tissue. The advantages of retroperitoneal lymphadenectomy following orchiectomy are discussed as treatment.
