Residual disability and psychosocial status after Guillain Barré syndrome: a 3 to 5 year follow-up study
No full textGuillain-Barré syndrome (GBS) is the most common cause of acute not-traumatic neuromuscular paralysis. Even if the disease usually has a good prognosis, recovery is not always complete and residual motor or sensory signs may remain. Little is known on the incidence of disability and long term psychosocial status in GBS. We present the results of a 3 to 5 year follow-up study of the residual signs, including fatigue, pain and psychosocial status in 75 GBS patients, aged from 20–82 years (mean 56). The functional grading at the onset and at the follow up was performed using the Hughes scale and the data about residual symptoms were obtained at the follow up by phone interview. Among the 56 patients interviewed, 44 (78%) were asymptomatic or had minimal signs of neuropathy (0–1 grade of Hughes scale), 7 (13%) remained moderately disabled (grade 2), 4 (7%) were unable to walk independently (grade 3), and one patient died. 51 (92%) were able to live independently at home while only 3 (5%) needed continuous or partial assistance. 33% of patients (18) reported fatigue in all their activities while 27% (15) had residual pain, which rarely caused restriction in daily living. 23% of patients (13) changed or temporarily or definitively suspended their job. 59% reached the maximum improvement in the first year while 21% continued to improve in the three following years. We observed that patients>40 years old were more severely impaired than the younger ones (76% vs 60% of patients had grade 4 or 5 of Hughes scale) while permanent disability was only observed in those aged>60 years (14% of patients vs none of the younger patients had grade 3). No difference was found in the outcome between patients with or without assisted ventilation. Patients reaching maximal worsening within 10 days achieved maximal improvement more quickly and remained less disabled than the others while those with>10 days plateau duration remained more severely impaired than those with a shorter duratio
SUCRALFATE, RANITIDINE AND NO TREATMENT IN GASTRIC ULCER MANAGEMENT - A MULTICENTER, PROSPECTIVE, RANDOMIZED, 24 - MONTH FOLLOW-UP WITH A STUDY OF RISK FACTORS OF RELAPSE
No full textThis multicenter, prospective, randomized, open, long-term study compares sucralfate (2 g daily) with ranitidine (150 mg daily) and no treatment in gastric ulcer (GU). We report the results of the second year of a scheduled 3-year follow-up, the outcome of the 1 st year has been reported earlier. The 24-month follow-up was completed by 142 patients who were continuously either treated with the drug randomly assigned at the beginning of the study or left untreated (i.e. 32 patients took 150 mg ranitidine at bedtime, 29 took 1 g sucralfate twice daily and 81 were left untreated, 23 of whom came from the ranitidine group, 19 from the sucralfate group and 39 from the untreated group). Seven patients dropped out and 26 subjects relapsed (5 under ranitidine, 4 under sucralfate and 17 untreated cases). Ranitidine versus previous ranitidine, sucralfate versus previous sucralfate and each one versus no treatment showed comparable relapse rates. An additional study, using Cox's models, showed that three variables have a significant correlation with relapse during the 1 st year of follow-up: therapy carried out (p = 0.0025), symptoms (p = 0.0047) and family history of ulcer (p = 0.0392). In conclusion, both ranitidine 150 mg and sucralfate 2 g proved effective in reducing GU relapse as compared with no treatment, an effect which does not seem to persist during the 2nd year of therapy, when the 'no treatment' option may be taken into account
Adherence to AIOM (Italian Association of Medical Oncology) lung cancer guidelines in Italian clinical practice: Results from the RIGHT-3 (research for the identification of the most effective and highly accepted clinical guidelines for cancer treatment) study
No full textObjectives: Clinical practice guidelines represent a key tool to improve quality and reduce variability of cancer care. In 2004, Italian Association of Medical Oncology (AIOM) launched the RIGHT (research for the identification of the most effective and highly accepted clinical guidelines for cancer treatment) program. The third step, RIGHT-3, evaluated the concordance between AIOM lung cancer guidelines and Italian clinical practice. Materials and methods: RIGHT-3 was a retrospective observational study, conducted in 53 Italian centers treating lung cancer. Sampling from AIOM database of 230 centers was stratified by presence of thoracic surgery and geographic distribution. To describe the adherence to AIOM guidelines (2009 edition), 11 indicators regarding diagnostic and treatment procedures were identified. Patients with non-small-cell lung cancer (NSCLC) diagnosis who had first visit in 2010 were divided into 3 groups, based on TNM stage: I-II-IIIA (5 indicators), IIIB (3 indicators) and IV (3 indicators). Results: 708 patients were enrolled; 680 were eligible: 225 patients in stage I-II-IIIA; 156 patients in stage IIIB; 299 patients in stage IV. Cyto-histological diagnosis was available in 96%, 97%, 96% of stage I-II-IIIA, IIIB, IV respectively. Positron-emission tomography was performed in 64% of stage I-II-IIIA and 46% of stage IIIB. 88% of stage I-II patients eligible for surgery underwent lobectomy; after surgery, 61% of stage II and 57% of stage IIIA patients received adjuvant chemotherapy. Among stage IIIB patients who received combined chemo- radiotherapy, sequential approach was more common than concomitant treatment (86% vs. 14%). Among stage IV patients, 87% received platinum-based first-line treatment, and 70% received second-line. Conclusion: The RIGHT-3 study showed that, in 2010, adherence to Italian NSCLC guidelines was high for many indicators (including those related to treatment of stage IV patients), but lower for some diagnostic procedures. Guidelines adherence monitoring can be useful to reduce variability in cancer care
Randomised study comparing 48 and 96 weeks peginterferon α-2a therapy in genotype D HBeAg-negative chronic hepatitis B
No full textObjective: Treatment with peginterferon α-2a (PegIFN) for 48 weeks is the standard of care for selected HBeAg-negative patients chronically infected with hepatitis B virus (HBV), but with limited treatment efficacy. A study was undertaken to investigate whether treatment extension to 96 weeks improves the outcome in this patient population. Methods: 128 HBeAg-negative patients (120 genotype D) were randomised to weekly 180 mg PegIFN for 48 weeks (group A, n=51), 180 μg PegIFN for 48 weeks followed by 135 mg weekly for an additional 48 weeks (group B, n=52) or 180 μg PegIFN plus lamivudine (100 mg/day) for 48 weeks then 135 μg PegIFN for 48 weeks (group C, n=25). Endpoints were alanine aminotransferase normalisation plus HBV DNA <3400 IU/ml (primary), HBV DNA <2000 IU/ml and HBsAg clearance at 48 weeks after treatment. Results: Forty-eight weeks after treatment, six patients in group A and 13 in group B achieved alanine aminotransferase normalisation plus HBV DNA <3400 IU/ml (11.8% vs 25.0%, p=0.08), 6 vs 15 patients had HBV DNA <2000 IU/ml (11.8% vs 28.8%, p=0.03), 0 vs 3 achieved HBsAg clearance (0% vs 5.8%, p=0.24) and 0 vs 5 had HBsAg <10 IU/ml (0% vs 9.6%, p=0.06). While extended PegIFN treatment was the strongest independent predictor of response, the combination with lamivudine did not improve responses. Discontinuation rates were similar among the groups (19.6%, 23.1%, 32.0%, p=0.81) and were mostly due to PegIFN-related adverse events. Conclusions: In HBeAg-negative genotype D patients with chronic hepatitis B, PegIFN treatment for 96 weeks was well tolerated and the post-treatment virological response improved significantly compared with 48 weeks of treatment.

Effect of interferon-alpha on progression of cirrhosis to hepatocellular carcinoma: a retrospective cohort study.
No full textAbstract
BACKGROUND:
There is debate about whether interferon-alpha treatment lowers the risk of progression to hepatocellular carcinoma in patients with chronic viral hepatitis and cirrhosis and whether any effect is limited to certain subgroups. We investigated these issues by retrospective analysis of data for 913 patients from Italy and Argentina.
METHODS:
21 centres reported patients from their records who had chronic viral hepatitis and Child's A cirrhosis, were positive for HBsAg or hepatitis-C-virus antibodies (anti-HCV), and had been screened yearly for at least 3 years by ultrasonography and alpha-1-fetoprotein testing. Prognostic risk factors for hepatocellular carcinoma defined by multivariate Cox regression analysis and individual observation time were used for group matching and conditional logistic regression analysis of the independent interferon-alpha treatment effect.
FINDINGS:
After group matching, the number of patients was reduced to 637. Age, male sex, and portal hypertension were significant risk factors for hepatocellular carcinoma (each p < 0.001); hepatic inflammation (p = 0.21) and iron storage (p = 0.18) were also included in the model 66 (19%) of 356 untreated patients and 29 (10%) of 281 treated patients developed hepatocellular carcinoma (relative risk 1.99 [95% CI 1.09-3.64]); the corresponding proportions for anti-HCV-positive patients were 48 (18.5%) of 259 versus 21 (9.1%) of 232 (3.14 [1.46-6.80]), and those for hepatitis-B-virus-infected (HBV) patients were 18 (10%) of 97 and eight (16%) of 49 (0.98 [0.33-2.92]). Among anti-HCV patients without HBV markers, 29 (20%) of 129 untreated and six (5%) of 116 treated patients developed hepatocellular carcinoma (6.28 [1.65-23.8]).
INTERPRETATION:
Interferon treatment lowered the rate of progression to hepatocellular carcinoma two fold. The risk reduction was apparently greater for patients with chronic hepatitis C and no evidence of HBV infection. Future studies should stratify HCV-infected patients by HBV status
The role of cumulative physical work load in symptomatic knee osteoarthritis : a case-control study in Germany
No full textObjectives To examine the dose-response relationship between cumulative exposure to kneeling and squatting as well as to lifting and carrying of loads and symptomatic knee osteoarthritis (OA) in a population-based case-control study. Methods In five orthopedic clinics and five practices we recruited 295 male patients aged 25 to 70 with radiographically confirmed knee osteoarthritis associated with chronic complaints. A total of 327 male control subjects were recruited. Data were gathered in a structured personal interview. To calculate cumulative exposure, the self-reported duration of kneeling and squatting as well as the duration of lifting and carrying of loads were summed up over the entire working life. Results The results of our study support a dose-response relationship between kneeling/squatting and symptomatic knee osteoarthritis. For a cumulative exposure to kneeling and squatting > 10.800 hours, the risk of having radiographically confirmed knee osteoarthritis as measured by the odds ratio (adjusted for age, region, weight, jogging/athletics, and lifting or carrying of loads) is 2.4 (95% CI 1.1-5.0) compared to unexposed subjects. Lifting and carrying of loads is significantly associated with knee osteoarthritis independent of kneeling or similar activities. Conclusions As the knee osteoarthritis risk is strongly elevated in occupations that involve both kneeling/squatting and heavy lifting/carrying, preventive efforts should particularly focus on these "high-risk occupations"
All repair and reconstruction. Techniques from the SANTI study group
No full textBackground: Combining an anterior cruciate ligament (ACL) reconstruction with an anterolateral ligament (ALL) reconstruction results in significant advantages including reduced graft rupture rates, a lower risk of reoperation for secondary meniscectomy, improved knee stability, and higher rates of return to preinjury levels of sport. Indications: The previously reported indications for combined ACL and ALL reconstruction are as follows: ACL reconstruction revision; high-grade pivot shift test; long-term ACL rupture; young patients; pivoting activities; concomitant medial meniscus repair, and, specifically, regarding the ALL repair, it must be an acute surgery (within 15 days from injury). Technique Description: Several modern techniques have been described to repair and reconstruct the ALL. This technical note details a number of these techniques performed by the Scientific Anterior Cruciate Ligament Network International (SANTI) Study Group. Results: First, we describe a combined ACL reconstruction and double-bundle ALL reconstruction using hamstring autograft. Secondly, we describe a single-bundle ALL reconstruction using gracilis autograft. Thirdly, we describe an ALL reconstruction technique using a knotless soft anchor, which provides shallow fixation and prevents tunnel convergence. Finally, we describe a technique for ALL repair. Conclusion: Several techniques have been described to repair and reconstruct the ALL, all offering significant advantages over an isolated ACL reconstruction.

Intraocular pressure-lowering effect of latanoprost monotherapy versus latanoprost or pilocarpine in combination with timolol: a randomized, observed-masked multicenter study in patient with open-angle glaucoma
No full textPURPOSE:
To compare intraocular pressure (IOP) after adding either latanoprost or pilocarpine to timolol treatment or switching to latanoprost monotherapy in glaucomatous eyes in which IOP was inadequately controlled with timolol.
METHODS:
This 6-month randomized study comprised 148 patients with primary open-angle or pseudoexfoliation glaucoma, which was inadequately controlled with topical beta-adrenergic antagonists. After a 2- to 4-week run-in period with timolol 0.5% twice daily, patients were assigned in randomized fashion to three study groups: one group received add-on therapy of latanoprost 0.005% once daily, the second group received add-on therapy of pilocarpine 2% three times daily, and the third group switched to latanoprost 0.005% once daily. Mean diurnal IOP was measured at baseline and after 3 and 6 months of treatment.
RESULTS:
At 6 months, 128 patients had completed the study. Diurnal IOP was significantly reduced from baseline in all groups. Adding latanoprost to timolol treatment reduced diurnal IOP by 6.1+/-0.3 mmHg (-28%), adding pilocarpine to timolol treatment reduced diurnal IOP by 4.2+/-0.3 mmHg (-19%), and switching from timolol to latanoprost monotherapy reduced diurnal IOP by 5.5+/-0.3 mmHg (-25%).
CONCLUSION:
A significantly greater reduction in diurnal IOP was achieved after addition of latanoprost than after addition of pilocarpine in patients in whom IOP was not adequately controlled with timolol alone. Further, the results of this study indicate that a switch to latanoprost monotherapy can be attempted before combination treatment is initiated
