Carotid stent failure: results of surgical rescue.

AIM: Little data is available on surgical "rescue" of failed carotid stents (CAS). We have analyzed a series of CAS failures treated by conventional open surgery. REPORT: Five patients underwent surgery after CAS failure, either electively (4) or as an emergency (1). Elective surgical "rescue" was for stent restenosis (2 cases) or stent misplacement (2 cases). Emergency surgery was performed for entrapment of the protection system in the stent. Surgical rescue was accomplished by perimedial endarterectomy and "en bloc" plaque and stent extraction in 3 cases, and by vein bypass in 2 cases, with no neurological complications. CONCLUSION: Surgical rescue of failed CAS is effective.

Alcoholics Anonymous and other 12-step programmes for alcohol dependence.

BACKGROUND: Alcoholics Anonymous (AA) is an international organization of recovering alcoholics that offers emotional support through self-help groups and a model of abstinence for people recovering from alcohol dependence, using a 12-step approach. Although it is the most common, AA is not the only 12-step intervention available there are other 12-step approaches (labelled Twelve Step Facilitation (TSF)). OBJECTIVES: To assess the effectiveness of AA or TSF programmes compared to other psychosocial interventions in reducing alcohol intake, achieving abstinence, maintaining abstinence, improving the quality of life of affected people and their families, and reducing alcohol associated accidents and health problems. SEARCH STRATEGY: We searched the Specialized Register of Trials of the Cochrane Group on Drugs and Alcohol, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE from 1966, EMBASE from 1980, CINAHL from 1982, PsychINFO from 1967. Searches were updated in February 2005. We also inspected lists of references for relevant studies. SELECTION CRITERIA: Studies involving adults (<18) of both genders with alcohol dependence attending on a voluntary or coerced basis AA or TSF programmes comparing no treatment, other psychological interventions, 12-step variants. DATA COLLECTION AND ANALYSIS: One reviewer (MF) assessed studies for inclusion and extracted data using a pre-defined data extraction form. Studies were evaluated for methodological quality and discussed by all reviewers. MAIN RESULTS: Eight trials involving 3417 people were included. AA may help patients to accept treatment and keep patients in treatment more than alternative treatments, though the evidence for this is from one small study that combined AA with other interventions and should not be regarded as conclusive. Other studies reported similar retention rates regardless of treatment group. Three studies compared AA combined with other interventions against other treatments and found few differences in the amount of drinks and percentage of drinking days. Severity of addiction and drinking consequence did not seem to be differentially influenced by TSF versus comparison treatment interventions, and no conclusive differences in treatment drop out rates were reported. Included studies did not allow a conclusive assessment of the effect of TSF in promoting complete abstinence. AUTHORS' CONCLUSIONS: No experimental studies unequivocally demonstrated the effectiveness of AA or TSF approaches for reducing alcohol dependence or problems. One large study focused on the prognostic factors associated with interventions that were assumed to be successful rather than on the effectiveness of interventions themselves, so more efficacy studies are needed.

Evidence of a selective epitope loss of anti-transglutaminase immunoreactivity in gluten-free diet celiac sera: a new tool to distinguish disease-specific immunoreactivities.

The aim of the present study was to evaluate the epitope specific humoral human tissue transglutaminase (tTG) immunoreactivity against 3 different human recombinant tTG constructs [(full-length tTG (a.a. 1-687), tTG (a.a. 227-687); tTG (a.a. 473-687)] before and after the introduction of a gluten-free diet (GFD). To this end, sera from 64 celiac disease (CD) subjects on a gluten-containing diet (44 f, 20 m) and after 0.6 +/- 0.3 years and 2.1 +/- 1.3 years of GFD were studied using a quantitative radioimmunoprecipitation assay. All 64 CD patients at diagnosis were full-length anti-tTG (a.a. 1-687)Ab positive. These Abs significantly decreased in frequency and titer after 6 months and 2 years of GFD. However, at low titers, 64.1% (41/64) of CD patients were still fl-tTG (a.a. 1-687)Ab positive after 2 years of GFD. At disease diagnosis, 70.3% (45/64) of the CD patients had Abs directed against fragments (227-687) and/or (473-687) of the tTG protein. This percentage, after 2 years of GFD, significantly decreased to 18.7%, whereas almost 50% of GFD patients had no tTG (227-687) and tTG (473-687) fragment reactivity, but only persistent, low-titer full-length tTG (1-687)Abs. We suggest that the selective loss of immunoreactivity against tTG (227-687) and tTG (473-687) fragments in CD patients with a GFD, could be due to quantitative decrease of autoreactivity driven by tTG-gliadin interaction underlying celiac disease pathogenesis.

Outcomes for early rectal cancer managed with transanal endoscopic microsurgery: a 5-year follow-up study.

BACKGROUND: This study aimed to evaluate the long-term risk of local and distant recurrence as well as the survival of patients with early rectal cancer treated using transanal endoscopic microsurgery (TEM). METHODS: The study reviewed 69 patients with Tis/T1/T2 rectal cancer treated using full-thickness excision between 1991 and 1999. The pathology T-stages included 25 Tis, 23 T1, and 21 T2. The median follow-up period was 6.5 years (range 5-10.2 years). RESULTS: The overall local recurrence rate was 8.7%. The 5-year local recurrence rate was 8% for Tis, 8.6% for T1, and 9.5% for T2. All six patients with recurrence were managed surgically. The 5-year disease-specific survival rate was 100% for Tis, 100% for T1, and 70% for T2. The overall cancer-related mortality rate was 7.2%. CONCLUSIONS: After local excision of early rectal cancer, a substantial local recurrence rate is observed. Patients with recurrent Tis/T1 cancers who undergo a salvage operation may achieve good long-term outcome. Local treatment without adjuvant therapy for T2 rectal cancers appears inadequate.

Methadone at tapered doses for the management of opioid withdrawal.

BACKGROUND: Despite widespread use in many countries the evidence of tapered methadone's efficacy in managing opioid withdrawal has not been systematically evaluated. OBJECTIVES: To evaluate the effectiveness of tapered methadone compared with other detoxification treatments and placebo in managing opioid withdrawal on completion of detoxification and relapse rate. SEARCH STRATEGY: We searched: Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2005), MEDLINE (January 1966 to December 2004), EMBASE (January 1988 to December 2004), PsycINFO (January 1985 to December 2004), and reference lists of articles. We also contacted manufacturers and researchers in the field. SELECTION CRITERIA: All randomised controlled trials which focus on the use of tapered methadone versus all other pharmacological detoxification treatments or placebo for the treatment of opiate withdrawal. DATA COLLECTION AND ANALYSIS: Two reviewers assessed the included studies. Any doubt about how to rate the studies were resolved by discussion with a third reviewer. Study quality was assessed according to the criteria indicated in Cochrane Reviews Handbook 4.2. (Alderson 2004) MAIN RESULTS: Sixteen trials involving 1187 people were included. Comparing methadone versus any other pharmacological treatment we observed no clinical difference between the two treatments in terms of completion of treatment, relative risk (RR) 1.12; 95% CI 0.94 to 1.34 and results at follow-up RR 1.17; 95% CI 0.72 to 1.92. It was impossible to pool data for the other outcomes but the results of the studies did not show significant differences between the considered treatments. These results were confirmed also when we considered the single comparisons: methadone with: adrenergic agonists (11 studies), other opioid agonists (four studies), chlordiazepoxide (study). Comparing methadone with placebo (one study) more severe withdrawal and more drop outs were found in the placebo group. The results indicate that the medications used in the included studies are similar in terms of overall effectiveness, although symptoms experienced by participants differed according to the medication used and the program adopted. AUTHORS' CONCLUSIONS: Data from literature are hardly comparable; programs vary widely with regard to duration, design and treatment objectives, impairing the application of meta-analysis. The studies included in this review confirm that slow tapering with temporary substitution of long acting opioids, accompanied by medical supervision and ancillary medications can reduce withdrawal severity. Nevertheless the majority of patients relapsed to heroin use.

Heroin maintenance for chronic heroin dependents.

BACKGROUND: Many medications have been used for stabilizing heroin users: Methadone, Buprenorphine and LAAM. The present review focus on the prescription of heroin to heroin dependents. OBJECTIVES: To assess the efficacy and acceptability of heroin maintenance versus methadone or other substitution treatments for opioid dependence, in retaining patients in treatment; reducing the use of illicit substances and improving health and social functioning. SEARCH STRATEGY: The Cochrane Central Register of Trials (CENTRAL) issue 1, 2005; MEDLINE 1966-2005, EMBASE 1980-2005 and CINAHL till 2005 (on OVID) were searched. There was no language or publication year restrictions. Many researchers were contacted for information. SELECTION CRITERIA: Randomised controlled trials of heroin (alone or combined with methadone) maintenance treatment compared with any other pharmacological treatments for heroin dependents. DATA COLLECTION AND ANALYSIS: The trials were independently assessed for inclusion and methodological quality by the reviewers. Data were extracted independently and double checked. Studies were not pooled together because of heterogeneity. MAIN RESULTS: 2400 references were obtained and 20 studies were eligible, 4 met the inclusion criteria for a total of 577 patients. The studies could not be analysed cumulatively because of heterogeneity of interventions and outcomes. Retention in treatment: no groups difference was found in two studies; one study (N=96) found RR=2.82 (95% CI 1.70-4.68) favouring heroin; one study (N=235) found RR 0.79 (95%CI 0.68-0.90) favouring methadone. Relapse to illegal heroin use (self- reported): in one study people using heroin in treatment was 64% (heroin group)and 59% (methadone group); in the other study the RR of heroin use was 0.33 (95%CI 0.15-0.72) favouring heroin. Criminal offence: one study showed the potential of heroin prescription in reducing the risk of being charged RR 0.32 (95% CI 0.14-0.78). Social functioning: two studies did not show statistical difference between intervention groups, and two studies considered criminal offence and social functioning as part of a multidomain outcome measure showing improvements among those treated with heroin plus methadone over those on methadone only. AUTHORS' CONCLUSIONS: No definitive conclusions about the overall effectiveness of heroin prescription is possible. Results favouring heroin treatment come from studies conducted in countries where easily accessible Methadone Maintenance Treatment at effective dosages is available. In those studies heroin prescription was addressed to patients who had failed previous methadone treatments. The present review contains information about ongoing trials which results will be integrated as soon as available.

Psychosocial treatment for opiate abuse and dependence.

BACKGROUND: Substance dependence is a major social and public health problem; therefore it is a priority to develop effective treatments. The treatment of opioid dependence is complex. Previous Cochrane reviews have explored the efficacy of pharmacotherapy for opiate dependence. This current review focuses on the role of psychosocial interventions alone for the treatment of opiate dependence. There are many different psychosocial interventions offered to opiate addicts, which are widely spread. There is some evidence for the effectiveness of psychosocial interventions, but no systematic review has even been carried out. OBJECTIVES: To assess the efficacy and acceptability of psychosocial interventions alone for treating opiate use disorders. SEARCH STRATEGY: Electronic searches of Cochrane Library, EMBASE, MEDLINE, and LILACS; reference searching; personal communication; conference abstracts; unpublished trials; book chapters on treatment of opioid abuse/ dependence. SELECTION CRITERIA: The inclusion criteria for all randomised-controlled trials were that they should focus on psychosocial interventions alone for treating opioid use disorders. DATA COLLECTION AND ANALYSIS: Reviewers extracted the data independently using relative risks, weighted mean difference and number needed to treat estimated, when possible. The reviewers assumed that people who died or dropped out had no improvement (intention to treat analysis) and tested the sensitivity of the final results to this assumption. MAIN RESULTS: Five studies fit the study criteria. These analysed Contingency Management, Brief Reinforcement Based Intensive Outpatient Therapy coupled with Contingency Management, Cue Exposure therapy, Alternative Program for Methadone Maintenance Treatment Program Drop-outs (MMTP) and Enhanced Outreach-Counselling Program. All the treatments were studied against the control (standard) treatment; therefore it was not possible to identify which type of psychosocial therapy was most effective. The main findings were that both Enhanced Outreach Counselling and Brief Reinforcement Based Intensive Outpatient Therapy coupled with Contingency Management had significantly better outcomes than standard therapy within treatment. This was regarding relapse to opioid use, re-enrollment in treatment and retention in treatment. At 1-month and 3- month follow up the effects of Reinforcement Based Intensive Outpatient Therapy were not sustained. There was no further follow up of the Enhanced Outreach Counselling group. The Alternative Program for MMTP Drop-outs and the behavioural therapies of Cue Exposure and Contingency Management alone were no better than the control (standard) therapy. As the studies were heterogeneous, it was not possible to pool the results and perform a meta-analysis. AUTHORS' CONCLUSIONS: The available evidence has low numbers and is heterogeneous. At present psychosocial treatments alone are not adequately proved treatment modalities or superior to any other type of treatment. It is important to develop a better evidence base for psychosocial interventions to assist in future rationale planning of opioid use drug treatment services. Large-scale randomised trials are required with longer follow up stating methods of randomisation, allocation concealment and blinding. Where possible this should include intention to treat analysis, with power calculations performed prior to the trial. These studies can be designed and delivered to provide usable data for better understanding of this important component of intervention in the field of dependence.

Pre-operative assessment of extramural invasion and sphincteral involvement in rectal cancer by magnetic resonance imaging with phased-array coil.

OBJECTIVE: Pre-operative staging of rectal cancer should identify patients with extrarectal spread, who might benefit from pre-operative radiotherapy, and patients with minimal sphincteral involvement, who can avoid permanent colostomy. The aim of this study was to assess the accuracy of Magnetic Resonance Imaging (MRI) to predict tumour stage and sphincter status. PATIENTS AND METHODS: Thirty-three patients with a rectal tumour were pre-operatively assessed by MRI with a phased-array coil. Imaging results were correlated with the final pathological findings. RESULTS: The overall accuracy of pre-operative staging with MRI was 88% (k = 0.75) for extramural tumour invasion and 59% (k = 0.26) for lymph node metastases. MRI correctly evaluated the infiltration of the anal sphincters in 87% of patients (7 of 8 patients with low rectal tumour). CONCLUSION: MRI provides the surgeon with valuable information regarding extramural tumour spread and sphincteral involvement, enabling appropriate selection of patients for pre-operative adjuvant therapy or sphincter-saving surgery.

Methadone at tapered doses for the management of opioid withdrawal.

BACKGROUND: Despite widespread use in many countries of tapered methadone for detoxification from opiate dependence, the evidence of efficacy to prevent relapse and promote lifestyle change has not been systematically evaluated. OBJECTIVES: To determine whether tapered methadone is effective to manage opioids withdrawal. SEARCH STRATEGY: We searched: the Cochrane Controlled Trials Register (Issue 1, 2000), MEDLINE (OVID 1966-2000), EMBASE (1980-2000); scan of reference list of relevant articles; personal communication; conference abstracts; unpublished trials from pharmaceutical industry; Internet (NIDA, Clinical Trials.org, BMJ). SELECTION CRITERIA: All randomised controlled trials focused on tapered methadone (length of treatment max 30 days) versus all other pharmacological detoxification treatments, placebo and different modalities of methadone detoxification programs for the treatment of opiate withdrawal. DATA COLLECTION AND ANALYSIS: One reviewer (LA) assessed studies for inclusion and undertook data extraction. Inclusion decisions and the overall process were confirmed by consultation between reviewers. Where possible analysis was carried out according to the "intention to treat" principles. MAIN RESULTS: 20 studies were included in the review, with 1357 participants. 10 studies compared methadone with adrenergic agonists, 7 studies compared different modalities of methadone detoxification, 2 studies compared methadone with other opioid agonists, 1 study with chlordiazepoxide, 1 with placebo. The conclusions of the 10 studies that compared methadone with adrenergic agonists showed no substantial clinical difference of the two treatments in terms of retention in treatment, degree of discomfort and detoxification success rates. The conclusions of the 6 studies that compare different methadone reduction schedules, showed that different types of methadone withdrawal schedule produce different responses in terms of withdrawal symptoms and severity of them. Regarding the studies that compare methadone with other opioid agonists, methadyl acetate performed similarly to methadone on most process and outcome measures, while methadone reduced severity of withdrawal and had fewer drop-outs than did propoxyphene. Using chlordiazepoxide vs methadone, the results suggest that the two drugs had similar results in terms of overall effectiveness. Comparing methadone with placebo more severe withdrawal and more drop outs were founded in the placebo group. The results indicate that tapered methadone and other medications used in the included studies are effective in the treatment of the heroin withdrawal syndrome, although symptoms experienced by subjects differed according to the medication used and the program adopted. It seems that regardless of which medication is selected for heroin detoxification, the rates of subsequent heroin abstinence are about equal. This suggests that the medications are similar in terms of overall effectiveness. Improvements were achieved when other services such as counseling and other supporting services were offered contemporaneously with detoxification. REVIEWERS' CONCLUSIONS: Data from literature are hardly comparable; programs vary widely with regard to duration, design and treatment objectives, impairing the application of meta-analysis. Results of many outcomes could not be summarised because they were presented either in graphical form or provided only statistical tests and p-values. For most studies standard deviation for continuous variables were not provided. The studies included in this review confirm that slow tapering with temporary substitution of long acting opioids, accompanied by medical supervision and ancillary medications can reduce withdrawal severity. Nevertheless the majority of patients relapsed to heroin use. However this cannot be considered a goal for a detoxification as heroin dependence is a chronic, relapsing disorder and the goal of detoxification should be to remove or reduce dependence on heroin in a controlled and human fashion and not a treatment for heroin dependence.

Psychosocial combined with agonist maintenance treatments versus agonist maintenance treatments alone for treatment of opioid dependence.

BACKGROUND: Methadone maintenance at proper doses is effective in retaining patients in treatment and suppressing heroin use. Questions remain regarding the efficacy of the psychosocial services that are offered by most maintenance programs. OBJECTIVES: To evaluate the effectiveness of any psychosocial plus any agonist maintenance treatment versus any agonist treatment alone in retaining patients in treatment, reducing the use of substances and improving health and social status. SEARCH STRATEGY: We searched the Cochrane Central Register of Trials (CENTRAL) issue 3, 2003; MEDLINE 1966-2003; EMBASE 1980-2003; PsycINFO 1985-2003; relevant web sites; scan of reference list of relevant articles. There were no language or publication restrictions. SELECTION CRITERIA: RCTs which focus on any psychosocial plus any agonist compared to any agonist maintenance intervention for opiate dependence. People aged less than 18 and pregnant women were excluded. Psychosocial in combination with antagonist maintenance treatment are excluded too. DATA COLLECTION AND ANALYSIS: The trials were independently assessed for inclusion and methodological quality by the reviewers. Data were extracted independently and double checked. MAIN RESULTS: The searching process resulted in the identification of 77 different studies: 12 studies met the inclusion criteria. These studies considered 8 different psychosocial interventions and 1 pharmacological treatment: Methadone Maintenance (MMT). The results show additional benefit in adding any psychosocial treatment to standard methadone maintenance treatment in relation to the use of heroin during the treatment RR 0.69 (95% CI 0.53-0.91); no statistically significant additional benefit was shown in terms of retention in treatment RR 0.94 (95% CI 0.85-1.02); and results at follow-up RR 0.90 (95% CI 0.76-1.07). REVIEWERS' CONCLUSIONS: The present evidence suggests that adding any psychosocial support to Standard MMT significantly improves the non-use of heroin during treatment. Retention in treatment and results at follow-up are also improved, although this findings did not achieve statistical significance. Insufficient evidence is available on other possible relevant outcomes such as Psychiatric symptoms/psychological distress, Quality of life. Limitations to this review are imposed by the heterogeneity of the trials both in the interventions and the assessment of outcomes. Results of studies were sometimes in disagreement and because of lack of detailed information no meta analysis could be performed to analyse the results related to the outcomes more often reported as positive results in the single studies. Duration of the studies was also too short to analyse other relevant outcomes such as mortality. In order to study the possible added value of any psychosocial treatment over an already effective treatment such as standard MMT, only big multi-site studies could be considered which define experimental interventions and outcomes in the most standardized way as possible.

Psychosocial and pharmacological treatments versus pharmacological treatments for opioid detoxification.

BACKGROUND: Different pharmacological approaches aimed at opioid detoxification are effective. Nevertheless a majority of patients relapse to heroin use, and relapses are a substantial problem in the rehabilitation of dependent heroin users. Some studies have suggested that the sorts of symptoms which are most distressing to addicts during detoxification are psychological symptoms rather than physiological symptoms associated with the withdrawal syndrome. OBJECTIVES: To evaluate the effectiveness of any psychosocial plus any pharmacological interventions versus any pharmacological alone for opioid detoxification, in helping patients to complete the treatment, reduce the use of substances and improve health and social status. SEARCH STRATEGY: We searched the Cochrane Central Register of Trials (CENTRAL) issue 3, 2003; MEDLINE 1966-2003; EMBASE 1980-2003; PsycINFO 1985-2003; relevant web sites; scan of reference list of relevant articles. There were no language or publication restrictions. SELECTION CRITERIA: Randomised controlled trials which focus on any psychosocial associated with any pharmacological intervention aimed at opioid detoxification. People less than 18 years of age and pregnant women were excluded. DATA COLLECTION AND ANALYSIS: The trials were independently assessed for inclusion and methodological quality by three reviewers. Data were extracted independently and double checked. MAIN RESULTS: The searching process resulted in the identification of 77 different studies: 8 studies met inclusion criteria. These studies considered 5 different psychosocial interventions and 2 substitution detoxification treatments: Methadone and Buprenorphine. The results show promising benefit from adding any psychosocial treatment to any substitution detoxification treatment in terms of completion of treatment RR 1.68 (95% CI 1.11-2.55), results at follow-up RR 2.43 (95% CI 1.61-3.66), and compliance RR 0.48 (95% CI 0.38-0.59). In respect of the use of heroin during the treatment, the differences were not statistically significant but favoured the combined treatments. REVIEWERS' CONCLUSIONS: Psychosocial treatments offered in addition to pharmacological detoxification treatments are effective in terms of completion of treatment, results at follow-up and compliance. Although a treatment, like detoxification, that exclusively attenuates the severity of opiate withdrawal symptoms can be at best partially effective for a chronic relapsing disorder like opiate dependence, this type of treatment is an essential step prior to longer-term drug-free treatment and it is desirable to develop adjunct psychosocial approaches that might make detoxification more effective. Limitations to this review are imposed by the heterogeneity of the assessment of outcomes. Because of lack of detailed information no meta analysis could be performed to analyse the results related to several outcomes.

Ultrasound of the elbow.

The elbow is an important synovial hinge joint of the upper extremity. This joint represents a common site of musculoskeletal symptomatology, affecting all age groups. The advantages of ultrasound imaging of the elbow include easy availability, multiplanar capability and the ability to assess structures dynamically. Patient symptomatology and site of maximal tenderness can be directly correlated with imaging findings. Comparison is easily made with the contralateral side. Particular strengths include the ability to assess para-articular structures, such as regional tendons and ligaments, in addition to assessment of joint effusions, loose bodies and regional bursae. With operator experience and excellent technique, ultrasound is a valuable imaging tool for assessment of disorders of the elbow joint.

Epidemiological, clinical and therapeutic features of AIDS-related Mycobacterium kansasii infection during the HIV pandemic: an 11-year follow-up study.

OBJECTIVES: Optimal diagnosis and timely treatment of atypical mycobacteriosis, and especially Mycobacterium kansasii disease, remain a serious challenge for clinicians engaged in the management of the immunocompromised host. METHODS AND RESULTS: From more than 2700 hospitalizations (over 1800 patients) attributable to HIV-associated disorders over an 11-year period, 12 patients were found to have a confirmed M. kansasii infection. This reflects the recent reduction in the frequency of this HIV-related complication, which virtually disappeared after the introduction of potent antiretroviral combinations in 1996. In the early 1990s, the lack of effective antiretroviral regimens made frequent the association with AIDS, a mean CD4 lymphocyte count of nearly 20 cells/microL, and an extremely variable chest X-ray features. The recent detection of a further case was attributable to late recognition of very advanced HIV disease, complicated by multiple opportunistic disorders. CONCLUSIONS: Mycobacterium kansasii respiratory or disseminated infection continues to occur, and poses diagnostic problems in terms of late or missed identification as a result of slow culture and frequently concurrent opportunistic disease. Serious therapeutic difficulties also arise from the unpredictable in vitro antimicrobial susceptibility profile of these organisms, and from the need to start an effective combination therapy that does not interfere with other medications as soon as possible.

Is carotid stenosis correlated with tympanosclerosis.

AIM: Tympanosclerosis and atherosclerosis seem to have a similar inflammatory origin despite the different tissues involved. We have investigated the possible relationship between tympanosclerosis and atherosclerosis by evaluating the incidence of tympanic plaques in patients with significant carotid disease. METHODS: Between September 1(st) 2002 and April 30th 2003, we have evaluated all patients undergoing carotid surgery for significant carotid stenosis (group A). If at least 1/5 of the eardrum was occupied by plaques, then the case was considered positive. A control group of patients of similar age and no history of otological nor vascular pathologies was enrolled (group B). The 2 groups were compared statistically by Fisher's test and significance was set at p=0.05. RESULTS: Group A consisted of 84 patients. In this group 32 patients (38.1%) had tympanosclerosis; it was bilateral in 12 cases. Group B had 84 patients. In this group tympanosclerosis was present in 11 cases (13%). The difference between the 2 groups was statistically significant (p=0.005). CONCLUSION: More studies are needed before we can understand the cause of the association between these 2 pathologies. However early screening of atherosclerotic disease in patients with tympanosclerosis seems justifiable on the basis of the data of both the literature and the present study.

Heroin maintenance for chronic heroin dependents.

BACKGROUND: Dependent heroin users are characterised by the persistence of use in spite of the difficulties they experience with health, law, social achievements and personal relationships. The present review will consider maintenance treatment in which the patients enter programs of pharmacological administration tailored to achieve patient stabilisation. Many medications have been used for this purpose such as: Methadone, Buprenorphine and LAAM. The present review will focus on maintenance treatment through the prescription of heroin. OBJECTIVES: To assess the efficacy and acceptability of heroin maintenance versus methadone or other substitution treatments for opioid dependence, in retaining patients in treatment; reducing the use of illicit substances and improving health and social functioning. SEARCH STRATEGY: The Cochrane Central Register of Trials (CENTRAL) issue 4, 2002; MEDLINE (on Silver Platter) 1966-2002; EMBASE (on OVID) 1980-2000 and CINAHL till 2000 were searched. There was no language or publication year restrictions. Many researchers were contacted for information. SELECTION CRITERIA: Randomised controlled trials of heroin (alone or combined with methadone) maintenance treatment compared with any other pharmacological treatments. DATA COLLECTION AND ANALYSIS: The trials were independently assessed for inclusion and methodological quality by the reviewers. Data were extracted independently and double checked. Studies were not pooled together because of heterogeneity. MAIN RESULTS: 2400 references were obtained and 20 studies were eligible, 4 met the inclusion criteria for a total of 577 patients. The studies included could not be analysed cumulatively because of heterogeneity of interventions and outcomes considered. Two studies compared injected heroin to oral methadone for 1 year (270 patients) but considered different outcomes; one study compared injected heroin and methadone to oral methadone for 6 months (51 patients); and one compared inhaled heroin and methadone to oral methadone for 1 year (235 patients). Retention in treatment: in two studies there was no statistical difference between groups; one study (N=90) had a RR=2.49 (95% CI 1.51-4.10) in favour of heroin; one study (N=235) had a RR 0.79 (95%CI 0.68-0.90) in favour of methadone. Relapse to illegal heroin use, based on self report: in one study the proportion of people still using heroin were 64% in the heroin group, 59% methadone group; in the other study the RR was 0.33 (95%CI 0.15-0.72) in favour of heroin. The remaining studies did not provide the data. Criminal offence: one of the two studies which provided details about this showed the potential of heroin prescription in reducing the risk of being charged RR 0.32 (95% CI 0.14-0.78). Social functioning: the two studies reporting this outcome did not show statistical difference between intervention groups. The two most recent studies considered criminal offence and social functioning as part of a multidomain outcome measure and showed higher improvement among those treated with heroin plus methadone over those on methadone only. REVIEWER'S CONCLUSIONS: No definitive conclusions about the overall effectiveness of heroin prescription is possible because of non-comparability of the experimental studies available to be included in this review. Results favouring heroin treatment come from studies conducted in countries where the treatment system is comprehensive and easy accessible Methadone Maintenance Treatment at effective dosages is available. In those studies heroin prescription was addressed to patients who had failed previous methadone treatments.

Body composition in coeliac disease adolescents on a gluten-free diet: a longitudinal study.

Our aim was to evaluate body composition in a group of coeliac disease adolescents on a gluten-free diet and to re-examine them at the end of the adolescence spurt. We studied 48 patients (group 1A), 30 age-matched healthy controls (group 2A), 11 group 1A patients after 4 years (group 1B) and 11 adolescents who were age- and sex-matched with group 1B (group 2B). Weight, height, bone mineral content, fat mass, fat-free mass (FFM) and bone mineral density were evaluated using dual-energy X-ray absorptiometry. All parameters were lower in group 1A than in group 2A subjects ( p<0.001). After 4 years, the body compartments of group 1B coeliac disease patients normalised, except for weight and FFM which remained lower than in group 2B subjects ( p<0.005). In conclusion, our study demonstrates that adolescence is a period where some parameters of body composition can still be recovered.

Celiac disease-associated transglutaminase autoantibody target domains at diagnosis are age and sex dependent.

The contribution of age and/or sex to the transglutaminase (tTG) autoantibody response in celiac disease (CD) is not known. To gain insights into transglutaminase humoral autoimmunity at CD diagnosis, our aim was to characterize the autoimmune response against three tTG constructs [(full-length tTG(a.a.1-687), tTG(a.a.227-687), and tTG(a.a.473-687)] and to investigate into its relationship with CD patients' age and sex. One hundred seventy-five newly diagnosed CD patients (115 females and 60 males), subdivided into different groups according to age and sex, were studied using a serum 35S-radioimmunoassay. We found that among full-length tTG autoantibody-positive CD subjects (175/175), 50.9% (89/175) and 83.4% (146/175) had autoantibodies against tTG(227-687) and tTG(473-687) domains, respectively. Female patients of less than 4 years expressed tTG(227-687)Abs in significantly higher percentage and mean autoantibody titers vs. all other groups investigated, and tTG(473-687)Abs in significantly higher titers with respect to adult female patients. Our data identify a subset of CD patients showing a strong humoral tTG immunoreactivity at diagnosis, thus suggesting that age and sex influence the anti-tTG autoantibody response.
