RESUMO

The supraclavicular artery island flap (SCAIF) is a thin and pliable pedicled flap that is easy and quick to harvest. Thanks to its particular features and high reliability, it is best indicated for the elderly or most fragile patients. SCAIF is very versatile, as it can be used for reconstruction of oral cavity, oropharynx, hypopharynx, facial and cervical skin and tracheostomal defects. We began using this flap in four Italian tertiary referral centres, with several indications, both as first treatment and as salvage surgery. The aim of the study was to demonstrate the easy reproducibility of the flap among four different centres. A series of 28 patients underwent head and neck reconstructions with SCAIF with no recorded complications during flap harvesting. After the very first cases, harvesting time was approximately 45 minutes; 24 patients had successful flap integration at the recipient site, while the remaining 4 suffered from partial flap necrosis, two of whom needed revision surgery. Other minor complications were reported at the recipient site, always at the most distal and most delicate portion of the flap. Donor site was always closed primarily, with only three cases of partial suture dehiscence. We only selected the most fragile patients for SCAIF reconstruction, such as the elderly or those with one or more comorbidities; for this reason, we reported some serious systemic complications and one intraoperative death. SCAIF is an easy reproducible flap, with multiple possible indications. Its use as an alternative to free flaps in the head and neck region is nowadays under discussion. Its use should be encouraged among head and neck surgeons thanks to its various advantages.

RESUMO

The introduction of microvascular free flaps has revolutionised modern reconstructive surgery. Unfortunately, access to training opportunities at standardised training courses is limited and expensive. We designed a pilot study on microvascular anastomoses with the aim of verifying if a short course, easily reproducible, could transmit microvascular skills to participants; if the chosen pre-test was predictive of final performance; and if age could influence the outcome. A total of 30 participants (10 students, 10 residents and 10 surgeons) without any previous microvascular experience were instructed and tested during a single 3 to 5 hour course. The two microanastomoses evaluated were the first ever performed by each participant. More than the half of the cohort was able to produce both patent microanastomoses in less than 2 hours; two-thirds of the attempted microanastomoses were patent. The pretest predicted decent scores from poor performances with a sensitivity of 61.5%, specificity of 100%, positive predictive value of 100% and negative predictive value of 40%. Students and residents obtained significantly higher scores than surgeons. Since our course model is short, cost-effective and highly reproducible, it could be introduced and implemented anywhere as an educational prospect for preselecting young residents showing talent and natural predisposition and having ambitions towards microvascular reconstructive surgery.

RESUMO

BACKGROUND AND AIMS: A high prevalence of atherosclerotic lesions characterizes patients with chronic kidney disease, though there is little data on the relationship between kidney function and atherosclerotic changes in the healthy population or in people with no known renal impairment. The aim of our study was to analyze, in a comprehensive general population with no known kidney disease, the relationship between renal function and subclinical carotid atherosclerotic damage. METHODS AND RESULTS: A general real-life population of 611 participants (233 males and 378 females; age ≥18 years) with no known kidney failure was selected for the study. The glomerular filtration rate (GFR) was estimated according to the CKD-EPI equation. Carotid intima-media thickness (c-IMT) and plaques were assessed by duplex Doppler ultrasonography of the carotid vessels. The main laboratory and metabolic parameters were evaluated in all participants. When we divided the overall study population into tertiles according to GFR values (I tertile <85; II tertile: 85-99; III tertile >99 ml/min/1.73 m2), the c-IMT mean values and the prevalence of carotid plaques decreased with the increasing tertile of GFR. On univariate analysis, c-IMT was significantly correlated with eGFR (r = -0.33; p < 0.001), serum creatinine (r = 0.17; p < 0.001), and other variables such as age, systolic blood pressure, waist circumference, fasting or random glycemia, and glycated hemoglobin (HbA1c). On multiple regression analysis, serum creatinine was associated with c-IMT (ß = 0.069; p = 0.017), independent of other covariates. CONCLUSION: Our study seems to suggest the importance of early identification of people with near normal or mildly decreased renal function due to its association with carotid atherosclerosis.

RESUMO

Nowadays, the transposition of microvascular free flaps is the most popular method for management of head and neck defects. However, not all patients are suitable candidates for free flap reconstruction. In addition, not every defect requires a free flap transfer to achieve good functional results. The aim of this study was to assess whether pedicled flap reconstruction of head and neck defects is inferior to microvascular free flap reconstruction in terms of complications, functionality and prognosis. The records of consecutive patients who underwent free flap or pedicled flap reconstruction after head and neck cancer ablation from 2006 to 2015, from a single surgeon, in the AOUC Hospital, Florence Italy were analysed. A total of 93 patients, the majority with oral cancer (n = 59), were included, of which 64 were pedicled flap reconstructions (69%). The results showed no significant differences in terms of functional outcome, flap necrosis and complications in each type of reconstruction. Multivariate regression analysis of flap necrosis and functional impairments showed no associated factors. Multivariate regression analysis of complicated flap healing showed that only comorbidities remained an explaining factor (p = 0.019). Survival analysis and proportional hazard regression analysis regarding cancer relapse or distant metastasis, showed no significant differences in prognosis of patients concerning both types of reconstruction. In this retrospective, non-randomised study cohort, pedicled flaps were not significantly inferior to free flaps for reconstruction of head and neck defects, considering functionality, complications and prognosis.

RESUMO

OBJECTIVES: Investigators hypothesized that cancer stem cells (CSCs) could play a role in determining cancer progression by metastasizing to cervical lymph node (N+) and then influencing prognosis of head and neck squamous cell carcinomas (HNSCCs) patients. DESIGN: To identify CSCs in HNSCCs and their clonogenic capacity. SETTING: In vitro study. PARTICIPANTS: Putative CSCs from 29 primary HNSCCs and 19 corresponding node metastases were analyzed. MAIN OUTCOME MEASURES: Immunohistochemical (IHC) was performed, and CSCs' clonogenic in vitro capacity was tested; ones epithelial nature of cancer cells forming colonies was confirmed by a second IHC, fluorescence-activated cell sorting (FACS) analysis helped in counting CD44/CD133-CSCs markers percentage expression in HNSCC tumour-derived cultures. RESULTS: Immunohistochemical showed CD44 (93.1%) and CD133 (10.34%) expression; FACS-analysis showed the enrichment of CD44/CD133 cancer cells, with the highest clonogenic capacity of CD44+-subpopulation; a higher CD44 rates were documented from N+ subcultures than from original tumours (P < 0.05). CONCLUSIONS: A putative cancer stem-like cell population is detectable in HNSCCs, and our findings show their in vitro clonogenic capacity by demonstrating that CD44+-cultured cells are the main population proliferating obtained by N+ HNSCC metastases, emphasizing their possible role in tumour progression.

RESUMO

A 23-year-old man was admitted to hospital with a 12-day history of daily fever. A clinical history revealed that 10 months previously, the patient had been splenectomized and polytransfused for a severe blunt trauma. On admission, laboratory data revealed significant leukocytosis (33,230/ul). The patient's general clinical conditions rapidly worsened into a severe systemic inflammatory response syndrome in four days. After 10 days of broad-spectrum antibiotic treatment, the temperature curve was unmodified and severe leukocytosis persisted (44,300 ul) with absolute lymphocytosis. Laboratory tests ruled out hematological diseases, pneumonia, abscesses and endocarditis. In the light of IgM positivity for CMV (unconfirmed by PCR) and with the support of a PubMed search, we commenced a salvage treatment with intravenous ganciclovir, suspecting a viral infection or reactivation. After two days of therapy, an immediate defervescence was observed with a remarkable clinical improvement. After 10 days, the clinical syndrome had been completely resolved and the patient was discharged in good, general clinical health.

RESUMO

BACKGROUND: Few studies examined the risk factors of asymptomatic bacteriuria, showing contradictory results. Our study aimed to examine the association between different clinical and laboratory parameters and asymptomatic bacteriuria in internal medicine patients. MATERIALS AND METHODS: 330 consecutive hospitalized subjects, asymptomatic for urinary tract infections (UTIs), underwent to microscopic examination of urine specimens. 100 subjects were positive for microscopic bacteriuria and were recruited into the study. At the quantitative urine culture 31 subjects of study population were positive while 69 subjects were negative for bacteriuria. RESULTS: The analysis of clinical characteristics showed that the two groups of subjects (positive and negative urine culture for bacteriuria) were significant different (p<0.05) about obesity (76.7% vs 42% respectively), metabolic syndrome (80.6% vs 44,9%), cholelithiasis (35.5% vs 13,2%) and iron deficiency anemia (80.6% vs 53,6%). The univariate analysis showed that only obesity, cholelithiasis and iron deficiency anemia were positively associated with positive urine culture for bacteriuria (Odds Ratios [OR]=3.79, p=0.0003; OR=2,65, p=0.0091; OR=2.63, p=0.0097; respectively). However, the multivariate analysis by logistic regression showed that only obesity and iron deficiency anemia, independently associated with positive urine culture for bacteriuria (OR=3.9695, p=0.0075; OR=3.1569, p=0.03420 respectively). CONCLUSIONS: This study shows that obesity and iron deficiency anemia are independent risk factors for asymptomatic bacteriuria.

RESUMO

BACKGROUND: The harmonic scalpel (HS) has been used successfully in several head and neck surgical procedures. Some authors highlighted its advantages in reducing operative time, blood loss, and damages to surrounding tissue. In our study, we compared the results obtained during parotidectomy using the HS with the traditional approach to determine the benefits of the HS. METHODS: 130 patients with benign parotid tumors were enrolled and randomized into two groups for this prospective study. 63 patients underwent HS parotidectomy, and 67 patients received a parotidectomy using cold instruments and bipolar electrocautery hemostatic control (CI). 20 HS and 2 CI patients did not meet the inclusion criteria requirements, and were excluded. RESULTS: The admission time was significantly shorter in the HS group than the CI group (3.9 ± 1.2 days and 4.7 ± 1.4 days, respectively, p < 0.01). In the early post-operative period, 84% of HS patients and 60% of CI cases showed no facial nerve impairment (p = 0.01). Significantly more CI patients than HS patients showed the onset of Frey's syndrome (29% and 9%, respectively, p = 0.01). Multivariate stepwise regression analysis confirmed the reduction in admission length (Odds Ratio (OR): 0.62; p = 0.02) and the lower risk of Frey's syndrome (OR: 0.29; p = 0.04) in HS compared to CI parotidectomies. CONCLUSIONS: In parotid surgery, the HS is useful in preventing Frey's syndrome and reducing early transitory facial nerve dysfunction and admission times, and results in decreased medical costs and increased quality of life.

RESUMO

Reconstructive surgery of the head and neck region has undergone tremendous advancement over the past three decades, and the success rate of free tissue transfers has risen to greater than 95%. It must always be considered that not all patients are ideal candidates for free flap reconstruction, and also that not every defect strictly requires a free flap transfer to achieve good functional results. At our institution, free flap reconstruction is first choice, although we use pedicled alternative flaps for most weak patients suffering from severe comorbidities, and for pretreated patients presenting a second primary or a recurrent cancer. From July 2006 to May 2010, 54 consecutive patients underwent soft tissue reconstruction of oral cavity and oropharyngeal defects. We divided the cohort in three groups: Group 1 (G1): 16 patients in good general conditions that received free radial forearm flap reconstruction; Group 2 (G2): 18 high-risk patients that received a reconstruction with infrahyoid flap; Group 3 (G3): 20 patients that received temporal flap (10 cases) or pectoral flap (10 cases) reconstruction. We must highlight that pedicled alternative flaps were used in elderly, unfavourable and weak patients, where usually the medical costs tend to rise rather than decrease. We compared the healthcare costs of the three groups, calculating real costs in each group from review of medical records and operating room registers, and calculating the corresponding DRG system reimbursement. For real costs, we found a statistically significant difference among groups: in G1 the average total cost per patient was € 22,924, in G2 it was € 18,037 and in G3 was € 19,872 (p = 0.043). The amount of the refund, based on the DRG system, was € 7,650 per patient, independently of the type of surgery. Our analysis shows that the use of alternative non-microvascular techniques, in high-risk patients, is functionally and oncologically sound, and can even produce a cost savings. In particular, the infrahyoid flap (G2) ensures excellent functional results, accompanied by the best economic savings in the worst group of patients. Our data reflect a large disconnection between the DRG system and actual treatment costs.

RESUMO

BACKGROUND: Neuropsychological rehabilitation efficacy in multiple sclerosis (MS) is a currently investigated issue. We reported, in a single blind controlled study, that an intensive short duration cognitive training of attention and executive functions significantly improves the treated functions and reduces depression in MS. The persistence of these effects over time are unknown. OBJECTIVE: To evaluate the persistence over time of neuropsychological improvement due to cognitive training nine months after rehabilitation onset. METHODS: This is a single blind randomized controlled study. 24 MS patients were randomly assigned to experimental group (n=13) and received PC assisted neuropsychological treatment for three months, or to control group (n=11), receiving no treatment. Patients were submitted to neuropsychological evaluation, depression and quality of life questionnaires at baseline, three months and nine months later. RESULTS: Nine months follow up compared to baseline evaluation shows a statistically significant improvement (p<0.05) in attention, information processing and executive functions tests (PASAT 3″, COWA/S, WCSTpe), in depression and quality of life questionnaires in rehabilitated patients only. reliable change index (RCI) and modified RCI confirmed the clinical significance of this improvement in rehabilitated patients. CONCLUSIONS: Three months intensive neuropsychological rehabilitation of attention, information processing and executive functions induces a long lasting and clinically relevant neuropsychological improvement over time and a persistent depression and quality of life amelioration in patients with RR MS.

RESUMO

The aim of the study was to evaluate the efficacy and potential pitfalls of selective neck dissection of levels II-IV in controlling occult neck disease in clinically negative neck (cN0) of patients with laryngeal squamous cell carcinoma. Charts of 96 consecutive cN0 laryngeal cancer patients undergoing 122 neck dissections at the University of Florence from January 2000 to December 2004 were reviewed. N0 neck was defined with contrast enhanced computed tomography scan. Occult neck disease rate was 12.5%, involvement per level was: 47.6% at level II, 38.1% at level III, 9.5% at level IV. Six patients developed neck recurrence (6.25%) after selective neck dissection of levels II-IV within the first two years after treatment. In conclusion, selective neck dissection of levels II-IV is effective in N0 laryngeal squamous cell carcinoma; posterior limits of surgical resection are missing therefore if post-operative radiation is required, the field should be extended beyond the dissected levels. The low incidence of occult neck disease indicates the need to refine treatment strategy, restricting elective neck dissection only to supraglottic T2 with epilaryngeal involvement, supraglottic T3-4 and glottic T4 tumours, and considering a "wait and see" protocol implemented with imaging techniques and cytological assessments for other lesions.

RESUMO

BACKGROUND AND AIMS: Metabolic syndrome (MS) has been mainly related to insulin resistance, but the role of changes in insulin secretion has not been thoroughly investigated. METHODS AND RESULTS: Using an oral glucose tolerance test (OGTT) we studied beta-cell function and insulin sensitivity in subjects with normal fasting glucose with and without MS, and their relationship to fatty liver which was evaluated by abdominal-ultrasonography. In MS early phase insulin secretion, as measured by insulinogenic index (IG(30)), was increased (p<0.05) independently from insulin sensitivity. Furthermore IG(30) was progressively higher as the number of factors needed for the diagnosis of MS increased (p<0.01). Insulin and C-peptide AUC were also increased (p<0.01 and p<0.05, respectively) but, in contrast to IG(30), these differences disappeared when ISI was used as a covariate. After OGTT, 51% of the subjects with MS had altered post-load glucose tolerance compared to 24.9% without MS (p<0.01). In both groups, the altered glucose tolerance was associated with a similar IG(30) reduction. In normo-tolerant subjects with MS the IG(30) was higher (+54.1%, p<0.01), and this elevation occurred irrespective of ISI; however, the beta-cell compensatory capacity for insulin resistance (disposition index) was impaired (p<0.001). Fatty liver was more frequent (p<0.001) and more severe (p<0.01) in MS, and it was significantly related to total AUC-insulin (p<0.001), independently from ISI. CONCLUSION: These findings indicate that the prevalence of altered tolerance is more frequent in subjects with normal fasting glucose and MS. The hyperinsulinemia might not only be an adaptive response to insulin resistance, but a primary defect of beta-cell function contributing to glucose intolerance.

RESUMO

AIMS: Occlusive coronary artery disease (CAD) is associated with left ventricular (LV) remodeling, LV systolic dysfunction, and heart failure. The BEAUTIFUL Echo substudy aimed to evaluate the effects of heart rate reduction with ivabradine on LV size (primary end-point: change in LV end-systolic volume index [LVESVI]) and function and the cardiac biomarker N-terminal pro-brain natriuretic peptide (NT-proBNP). METHODS AND RESULTS: The substudy was carried out in 86 centers participating in the BEAUTIFUL study. 2D echocardiography was performed at baseline, and after 3 and 12 months in patients with stable CAD and LV systolic dysfunction receiving ivabradine or placebo at the same time-points. All data were read and analyzed centrally. Of 525 patients completing the study, 426 had adequate echocardiographic readings (n = 220 ivabradine; n = 206 placebo). Treatment with ivabradine was associated with a decrease in the primary end-point LVESVI (change from baseline to last value, -1.48 ± 13.00 mL/m(2)) versus an increase with placebo (1.85 ± 10.54 mL/m(2)) (P=0.018). There was an increase in LV ejection fraction with ivabradine (2.00 ± 7.02%) versus no change with placebo (0.01 ± 6.20%) (P=0.009). Reduction in LVESVI was related to the degree of heart rate reduction with ivabradine. There were no differences in any other echocardiographic parameters or NT-proBNP. Change in LVESVI was related to the log change in NT-proBNP in the ivabradine group only (r = 0.18, P = 0.006). CONCLUSIONS: Our observations suggest that ivabradine may reverse detrimental LV remodeling in patients with CAD and LV systolic dysfunction.

RESUMO

AIM: Patients with heterozygous familial hypercholesterolemia (FH) have an increased risk of premature myocardial infarction, stroke, and surgical revascularization, and an increased rate of progression of carotid intima-media thickness (IMT). The most commonly used drugs for cholesterol lowering, statins, have a limited action in these patients. Ezetimibe, a novel compound, selectively inhibits cholesterol uptake and when associated with statins has an additional low-density lipoprotein cholesterol (LDL-C) reducing effect. The aim of this study is to evaluate the effects of long-term combined Ezetimibe/Simvastatin (EZE/SIMVA) therapy (30 months) on the lipidic pattern, inflammatory markers, and carotid IMT in patients with FH subdivided into two groups: one with a history of acute myocardial infarction (IMA) and the other with carotid atherosclerotic plaques but no history of cardiovascular events. METHODS: All patients enrolled in this study (group A: patients with a history of IMA; group B, patients with carotid lesions but no history of cardiovascular events) were submitted to a 6-week period of isocaloric diet and to a 4-week lipid-lowering wash-out period before study entry. After the wash-out period at baseline (time 0) and then every two months total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), and apolipoprotein B and A1 were determined. LDL-C levels were calculated. Fibrinogen and hs-CRP at baseline and at 6, 18, and 30 months were determined. All patients were submitted to an ultrasonographic evaluation of the carotid intima-media thickness at baseline, 18 and 30 months. The scheduled duration time of the study was 30 months. At the beginning of the study all patients were assigned to receive the combined EZE/SIMVA treatment 10/20 mg per day. After two months, patients who had not reached the respective LDL-C targets proposed by NCEP ATPIII (<70 mg/dL for patients with a history of IMA and <100 mg/dL for patients with carotid lesions) were assigned to receive EZE/SIMVA 10/40 mg per day and, after four months, patients who had not reached the respective LDL-C targets were assigned to receive EZE/SIMVA 10/80 mg per day. RESULTS: At the end-point, significant reductions (P<0.001) of about 70% in LDL-C, of 57% in total cholesterol (TC), of 46% in Apo-B, and of 46% in hs-C-reactive protein (hs-CRP) were observed in both groups compared to baseline. Also, triglyceride and fibrinogen levels were significantly (P<0.01) reduced, respectively by 26% and 15% compared to baseline. The EZE/SIMVA association resulted in significant increases in HDL-C (P<0.01) of 11% and in Apo-A1 (P<0.05) by 9% and in significant (P<0.001) reductions of the mean of the carotid IMT in both groups. The EZE/SIMVA treatment was generally well-tolerated, with a safety profile on laboratory parameters. During the 30-month scheduled period of the study, no patient in either group presented any further cardiovascular events. CONCLUSION: In patients with FH, combined EZE/SIMVA treatment resulted in a significant LDL-C lowering, achieving the goals proposed by NCEP ATP III, in a significant improvement of all the lipidic and inflammatory patterns, and above all in a progressive decrease of the carotid IMT. Although the results of ongoing randomized controlled trials are required before making any definitive conclusions, our results support the hypothesis of stabilizing effect of EZE/SIMVA on the atherosclerotic disease both in primary and in secondary prevention.

RESUMO

BACKGROUND: On top of aspirin, an abciximab bolus-only regimen results in a 30% drop in platelet inhibition at 6 h as compared with the on-label regimen. The concomitant administration of high loading dose clopidogrel, by bridging with abciximab bolus, may sustain suppression of platelet activity over time. OBJECTIVES: To investigate the non-inferiority of abciximab bolus-only and concomitant high loading dose clopidogrel vs. abciximab bolus + infusion with respect to the inhibition of platelet aggregation (IPA) as determined by light transmission aggregometry. PATIENTS/METHODS: Seventy-three patients with non-ST segment elevation acute coronary syndromes underwent double-blind randomization to abciximab bolus followed by a 12-h placebo infusion and concomitant 600-mg clopidogrel vs. abciximab bolus + a 12-h infusion and 300 mg of clopidogrel. IPA was determined by light transmission aggregometry throughout 24 h. Clopidogrel poor responsiveness was defined as ≥ 50% 5 µmol L⁻¹ ADP-induced maximum platelet aggregation. RESULTS: In clopidogrel responders (n = 68), IPA after 20 µmol L⁻¹ ADP at 4 h was 89% ± 13% in the bolus-only arm vs. 92% ± 14% in the bolus + infusion arm (P = 0.011 for non-inferiority). IPA after 5 or 20 µmol L⁻¹ ADP and 5 or 15 µmol L⁻¹ TRAP and the proportion of patients showing ≥ 80% IPA did not differ at any time point, irrespective of clopidogrel responsiveness status. Thirty-day outcomes were similar, whereas hemoglobin (0.91 ± 0.8 vs. 0.5 ± 0.7 g dL⁻¹ ; P = 0.01) and platelet count mean drop (41.7 ± 57 vs. 18.6 ± 34 109 L⁻¹; P = 0.042) were significantly reduced in the bolus-only arm. CONCLUSIONS: Withholding abciximab post-bolus infusion in patients receiving high loading dose clopidogrel does not impair platelet inhibition throughout 24 h, and has the potential to improve the safety profile of the drug at reduced costs.

RESUMO

To assess the risk from exposure to occupational stress and burnout in health care workers (HCW), a cross-sectional study was planned to compare objective data that can represent potential job stressors in hospital wards and subjective symptoms reported by the workers. Medical doctors, nurses and ancillary workers of the Internal Medicine Wards of a large public hospital in Northern Italy were enrolled in the study. Three subjective questionnaires were administered: the Job Content Questionnaire, the State-Trait Anxiety Inventory, the Maslach Burnout Inventory. In addition, seven objective parameters were collected as average on the 3 months period prior to the study: a) working understaffed; b) number of patients/HCW on service; c) number of HCW on sick leave/on service; d) number of skipped days off after night shifts; e) number of sick leaves; f) number of deceased patients; g) number of accidents at work. A total group of 230 HCW were examined, employed in six different sub-units of the Medical wards. The female workers were 67.8% and the male workers 32.2%, the mean age was 37.4 years (SD 9.3) in the total group, 35.1 years (SD 7.9) in females and 42.3 years (SD 10.3) in males. The average scores of subjective and objective parameters resulted significantly higher in the same sub-units. The correlation analysis showed that the subjective questionnaires were highly inter-related. The multivariate analysis showed that the number of sick leave days was significantly related to the subjective questionnaires, and the subjective subscales of emotional exhaustion, job demand, decision latitude and STAIt were significantly related to some of the objective parameters. Therefore, the best approach to measure occupational stress is an integrated one, which involves the use of multiple subjective and objective assessment modalities.

RESUMO

BACKGROUND: A multidisciplinary intervention is necessary to tackle the occupational risk of low back disorders in manual handling ofpatients and to evaluate the effectiveness. METHODS: An intervention was carried out which included risk assessment, testing and purchasing of patient handling devices, training programmes, health surveillance and collection of quantitative and qualitative outcomes to evaluate effectiveness, in a before-after design. RESULTS: The intervention was effective in reducing exposures, increasing knowledge and skills in patient-handling techniques, decreasing low back pain prevalence and injuries related to patient handling; absenteeism seemed to show a decreasing trend. CONCLUSIONS: The multidisciplinary approach was useful in the overall management of low back pain in health care workers performing patient handling.
