RESUMO

Chronic migraine is a debilitating headache, whose treatment is often complicated by the concomitant overuse of symptomatic medication and by the poor efficacy of standard prophylactic treatments. The PREEMPT studies have demonstrated the efficacy and tolerability of onabotulinum toxin A (Botox(®)) in the treatment of this headache type. Data about its use in clinical practice are still scarce. Our study evaluated all subjects with chronic migraine who were treated with onabotulinum toxin A between February 2014 and November 2015 at the Parma Headache Centre. Botox was injected according to the PREEMPT paradigm every 3 months. The data about variations in the number of headache days and in symptomatic medication intake before and after the Botox injections were collected from the patients' headache diaries. The study also evaluated tolerability to treatment, disability, and depressive symptoms. Of the 52 treated subjects, 14 received Botox treatment for at least 9 months and showed a significant decrease in the median number of headache days (from 19 to 14.5, p = 0.011) and in the median number of days of symptomatic medications intake and symptomatic drugs. Overall, the treatment was well tolerated. The average MIDAS and BDI-II scores after 9 months were reduced, though not significantly. The treatment with Botox proved effective and well tolerated in our clinical practice. Further studies on larger patient samples will help shed light on the persistence of the drug's effect at long term and identify the predictive factors of response to treatment.

RESUMO

In cultural-heritage-related indoor environments, biological particles represent a hazard not only for cultural property, but also for operators and visitors. Reliable environmental monitoring methods are essential for examining each situation and assessing the effectiveness of preventive measures. We propose an integrated approach to the study of biological pollution in indoor environments such as libraries and archives. This approach includes microbial air and surface sampling, as well as an investigation of allergens and pollens. Part of this monitoring plan has been applied at the Palatina Library in Parma, Italy. However, wider collections of data are needed to fully understand the phenomena related with biological contamination, define reliable contamination threshold values, and implement appropriate preventive measures.

RESUMO

BACKGROUND: In some countries, community health workers (CHWs) act as a bridge between the health care delivery system and the community, and ensure primary health care. It is essential to improve health worker education and training; however, in remote areas such as rural Senegal villages, these CHWs are often unable to leave their home community for training and education. We set out to perform a training program in a village in Senegal and to evaluate its effectiveness in that village. METHODS: We prepared a training program to be based on face-to-face lessons and practical exercises; a nurse from the university of Parma carried out the training of the CHW in loco for a period of four weeks. After six months, the nurse with an anthropologist returned to the village to verify the results of the training program. RESULTS: The CHW had retained most of what she had been taught, but her opinion about the training program was not altogether positive, given that the absence of a working health centre in the village and an insufficient period of practical experience in a hospital. The village community did not understand the role of the CHW and was not informed that there was a training program to help increase her technical know-how. CONCLUSIONS: This experience confirmed the important role of the CHW in rural areas in a poor region in Senegal, in the absence of other professional healthcare figures readily accessible to the population. Nonetheless, in order to properly carry out the role of CHWs, an adequate theoretical and practical training is necessary.

RESUMO

A hospital case record study was carried out enlisting urgently hospitalized subjects for chronic obstructive pulmonary disease (COPD) in order to study the percentage values variations of Vital Capacity (VC), Forced Vital Capacity (FVC) and maximum expiratory volume in 1 second (FEV1) based on atmospheric pollution trend in Parma city evaluated by PM10, NO2 and O3 concentrations. The results showed an association only between PM10 and hospitalizations for COPD with statistically significant differences between PM10 concentrations assessed 3-4 days before hospitalizations of the study subjects and the ones established in the days without any hospitalization. The regression analysis between PM10 and respiratory function concerning PM10 concentration at 24, 48, 72, 96 hours before the hospitalization showed significant association between FVC% and FEV1% and PM10 concentrations at 96 hours. The calculated odd ratio resulted equal to 1016 (L.C. 1001-1032) which corresponds to an increase of hospitalization probability for COPD equal to 1.6% for PM10 increment unit.

RESUMO

BACKGROUND: Infection is one of the most feared complications of surgery. New instrumentation is being developed to reduce deposition of bacteria. METHODS: We investigated 45 major surgical procedures (21 radical nephrectomies [RN] and 24 radical retropubic prostatectomies [RRP]) in our urology department during 2007. In about one-half of the interventions, an ultraclean air flow mobile (UAF) unit was used. Bacterial sedimentation was evaluated by nitrocellulose membranes placed on the instrument tray and by settle plates positioned at four points in the operating room. In 27 operations, an additional membrane was located near the incision. RESULTS: Bacterial counts on the nitrocellulose membranes during RN were 230 colony-forming units (cfu)/m(2)/h with the UAF unit and 2,254 cfu/m(2)/h without the unit (p = 0.001). During RRP, the values were 288 cfu/m(2)/h and 3,126 cfu/m(2)/h respectively (p = 0.001). The membrane placed near the incision during RN showed a microbial count of 1,235 cfu/m(2)/h with the UAF unit and 5,093 cfu/m(2)/h without the unit (p = 0.002); during RRP, the values were 1,845 cfu/m(2)/h and 3,790 cfu/m(2)/h, respectively (difference not significant). Bacterial contamination detected by settle plates during RN showed a mean value of 2,273 cfu/m(2)/h when the UAF unit was used and 2,054 cfu/m(2)/h without the unit; during RRP, the values were 2,332 cfu/m(2)/h and 2,629 cfu/m(2)/h with and without the UAF unit, respectively (NS). No statistically significant differences were detected in the clinical data registered in patients operated on under standard conditions and while the UAF unit was functioning. CONCLUSIONS: The UAF appears able to reduce microbial contamination at the operating table, reaching a bacterial number obtained in ultraclean operating theatres.

RESUMO

PURPOSE: This study is aimed at verifying if the surgeon's experience has an impact on the risk of conversion to open surgery of laparoscopic left colectomy performed in obese patients. METHODS: A multiple logistic regression analysis was performed of 181 laparoscopic left hemicolectomies completed between April 2001 and June 2006. The results were analysed statistically in relation to the learning curve, by comparing factors that could have had an impact on the risk of conversion in the first 91 cases and in the last 90 cases. RESULTS: The overall conversion rate was 11%. Only weight level was found to be predictive of conversion to open surgery. No death was observed. Sixteen patients presented postoperative complications (8.8%), with no significant differences between obese and nonobese patients (P=0.95). The conversion rate was higher in the group of the first 91 cases: 15.6% versus 6.6% (P=0.05). Average body mass index of converted patients resulted as being higher than that of nonconverted ones (29.97+/-3.76 vs. 25.48+/-3.72; P<0.001) during the first period of the learning curve, but the difference was not observed during the second period (P=0.87). On multiple logistic regression analysis, obesity was found to be predictive of conversion only during the first period. CONCLUSIONS: The data indicate that the laparoscopic colorectal surgery is feasible and effective in obese patients both when the surgeon is expert in laparoscopic colorectal resection and at the initial phase of the experience. At the initial phase of the experience obesity constitutes a higher risk of conversion to open surgery.

RESUMO

OBJECTIVE: The objective of this study was to assess the relationship between active smoking as well as environmental tobacco smoke (ETS) exposure and severe small for gestational age (SGA) at term in a sample of pregnant Italian women. METHODS: A case-control study was conducted in nine cities in Italy between October 1999 and September 2000. Cases of severe SGA were singleton, live born, at term children with a birth weight 10(th) percentile for gestational age. A total of 84 cases of severe SGA and 858 controls were analyzed. A self-administered questionnaire was used to assess active smoking and ETS exposure, as well as potential confounders. RESULTS: Multivariate logistic regression analysis showed a relationship between active smoking during pregnancy and severe SGA (adjusted odds ratio (OR) 2.10, 95% confidence interval (CI) 1.13-3.68). ETS exposure was associated with severe SGA (adjusted OR 2.51, 95% CI 1.59-3.95) with a dose-response relationship to the number of smokers in the home.

RESUMO

Air microbial sampling is a subject of great interest in different fields of human activity; however, generally accepted indications, concerning both the sampling methods to be used and the interpretation of the results, are still lacking. The whole theme is greatly debated and several problems remains to be solved. The aim of this article is to provide knowledge relating to the problems associated with air microbial sampling, underlining the aspects to be considered in order to choice the sampling method on the basis of the objective of the sampling itself and on the knowledge of the characteristics and limits of the different methods.

RESUMO

BACKGROUND: The aim of the study was to evaluate the effectiveness of subtotal colectomy with cecorectal anastomosis (SCCA) in the treatment of slow-transit constipation, not just in terms of symptom resolution but also the overall impact on patients' quality of life. METHODS: Between 1991 and 2005, 43 patients underwent SCCA at our institution, 22 for slow-transit constipation (STC) and 21 for other types of colic diffuse disease (non-slow-transit constipation: NSTC), the latter being considered controls. A total of 29 patients (17 affected by STC) were administered a 50-item telephonic questionnaire, including the Gastrointestinal Quality of Life Index (GIQLI), the Wexner constipation and incontinence scale (WC, WI), and individual willingness to repeat the procedure. Questionnaire data and other parameters such as age, sex, length of follow-up, complications, and length of hospital stay were analyzed and compared, in order to evaluate possible correlations between the parameters and their related impact on quality of life, procedural effectiveness in terms of symptomatic regression, qualitative differences related to pathology (constipation versus non-constipation), and surgical approach (laparotomy versus video-laparo-assisted procedure). RESULTS: There were no procedure-related deaths in this series (mortality: 0%); however, we found two complications in the STC group (9.1%), one requiring reoperation. The GIQLI mean score for the STC group was 115.5 +/- 20.5 (mean score for healthy people 125.8 +/- 13), and the WC mean score passed from a preoperative value of 20.3 to a postoperative value of 2.6. Regression analysis revealed a significant correlation between GIQLI and urgency and abdominal pain, and abdominal pain correlated significantly with pathology (STC). A high number of patients (88.2% in STC) expressed a willingness to repeat the procedure given the same preoperative conditions. CONCLUSIONS: Comparing our results to those of the most homogeneous literature data, SCCA does not appear to be inferior to subtotal colectomy with ileorectal anastomosis (IRA) in terms of therapeutic effectiveness, postoperative mortality and morbidity, or overall impact on quality of life.

RESUMO

BACKGROUND: It is still a matter of debate as to whether resective surgery of the primary tumor may prolong the survival of patients affected by incurable colorectal cancer (CRC). The main goal of this retrospective study, carried out on patients not undergoing any therapy other than surgery, was to quantify the benefit of primary tumor removal in patients with differently presenting incurable CRC. METHODS: One hundred and thirty consecutive patients were operated on for incurable CRC (83 undergoing resective and 47 non-resective procedures). With the purpose of comparing homogenous populations and of identifying patients who may benefit from primary tumor resection, the patients were classified according to classes of disease, based on the "metastatic pattern" and the "resectability of primary tumor." RESULTS: In patients with "resectable" primary tumors, resective procedures are associated with longer median survival than after non-resective ones (9 months vs 3). Only patients with distant spread without neoplastic ascites/carcinosis benefit from primary tumor removal (median survival: 9 months vs 3). Morbidity and mortality of resective procedures is not significantly different from that of non-resective surgery, either in the population studied or in any of the groups considered. CONCLUSIONS: Palliative resection of primary CRC should be pursued in patients with unresectable distant metastasis (without carcinomatosis), and, intraoperatively, whenever the primary tumor is technically resectable.

RESUMO

The aim of this study was to assess the relationship between preterm/early preterm delivery and active smoking as well as environmental tobacco smoke (ETS) exposure in a sample of pregnant Italian women. A case-control study was conducted in nine cities in Italy between October 1999 and September 2000. Cases of preterm birth were singleton babies born before the 37th gestational week; babies born before the 35th gestational week were considered early preterm births. Controls were babies with gestational ages >or= 37th week. A total of 299 preterm cases (including 105 early preterm) and 855 controls were analysed. A self-administered questionnaire was used to assess active smoking and ETS exposure, as well as potential confounders. Multivariable logistic regression analysis showed a relationship between active smoking during pregnancy and preterm/early preterm delivery [adjusted ORs: 1.53; 95% CI 1.05, 2.21 and 2.00; 95% CI 1.16, 3.45, respectively]. A dose-response relationship was found for the number of cigarettes smoked daily. The adjusted ORs were 1.54 and 1.69 for preterm babies and 1.90 and 2.46 for early preterm babies for 1-10 and >10 cigarettes/day respectively. ETS exposure was associated with early preterm delivery [adjusted OR 1.56; 95% CI 0.99, 2.46] with a dose-response relationship with the number of smokers in the home. Smoking during pregnancy was strongly associated with preterm delivery with a dose-response effect. ETS exposure in non-smoking women was associated only with early preterm delivery.

RESUMO

PURPOSE: The objective of this study was to quantify the risk of conversion to open surgery of laparoscopic left hemicolectomy at an early stage of the learning curve. METHODS: A multiple logistic regression analysis of 100 laparoscopic left hemicolectomies completed between April 2001 and May 2004 was performed. RESULTS: The overall conversion rate was 12%. At univariate analysis, 2 factors were found to be predictive of conversion to open surgery: malignancy (17.2% vs. 5%; P=0.046), and weight level (<60 kg=6.1%; 60 to 90 kg=11.3%; >90 kg=28.6%; P=0.049). At multiple logistic regression, the risk of conversion rose only for patients weighing more than 90 kg. CONCLUSIONS: On the basis of the results of this study, the surgeon will be able to quantify the risk of conversion to laparotomy with some precision in order to obtain the informed consent of the first 100 patients to whom laparoscopic left hemicolectomy is proposed.

RESUMO

BACKGROUND: Short-term outcome and anorectal function results after laparoscopic hemicolectomy for colon cancer were compared with results after laparoscopic hemicolectomy for benign diseases. METHODS: A total of 108 patients who underwent laparoscopic left colectomy (60 for colon cancer, 48 for diverticulitis or polyposis) were enrolled in the study. Left hemicolectomy in patients affected by cancer was performed by high ligation of the inferior mesenteric artery. A questionnaire concerning anorectal function was mailed to patients 6 months after surgery. RESULTS: Complications were more frequent in the cancer group than in the benign disease group: overall morbidity rate (29.6% versus 8.7%; P = 0.009), diarrhea during the first 6 postoperative months (58.7% versus 34.1%; P = 0.022), and anorectal function problems (fecal incontinence and/or the inability to discriminate between gas and stool, and/or urgency, and/or tenesmus) (65.2% versus 31.7%; P = 0.002). DISCUSSION: The level of ligation of the lower mesenteric artery and damage at the lower mesenteric ganglion could explain the poorer anorectal function outcome in the colon cancer group.

RESUMO

BACKGROUND: The aim of this study was to evaluate the subjective anorectal function in patients with left hemicolectomy and to clarify the clinical factors influencing postoperative anorectal function problems. MATERIALS AND METHODS: One hundred and twenty one patients who underwent left hemicolectomy from April 2002 to December 2003 were enrolled in this study and sent questionnaires concerning anorectal function. Left hemicolectomy in patients with cancer was performed by high ligation of the inferior mesenteric artery; in patients with diverticulitis or polyposis, the inferior mesenteric artery was cut just below the branch of the left colonic artery. One hundred patients replied to the questionnaire: 52 men and 48 women, aged 37 to 85, with a mean age of 66.6 years. Differences were analyzed for statistical significance by the Chi square test and by logistic regression. RESULTS: Anorectal function problems was present in 33% of patients: female gender (P = 0.02), laparoscopic surgery (P = 0.04), and postoperative diarrhea (P = 0.04) had significant independent effects on anorectal function problems. Transient early fecal incontinence was observed in 16% of patients and laparoscopic surgery had significant independent effects on this problem (P = 0.04). Inability to discriminate between gas and stool, tenesmus, or urgency were present in 21%, 18%, and 17% of cases, respectively, and were independently associated respectively with laparoscopic surgery (P = 0.005) and postoperative diarrhea (P = 0.019) (P = 0.015). CONCLUSION: In our study the following two issues were clarified: anorectal function problems are frequent after left hemicolectomy, and the laparoscopic technique is linked to poor postoperative anorectal function. The technical methods of high ligation of the inferior mesenteric artery could explain this result.

RESUMO

Polychlorinated Biphenyls are synthetic chlorinated hydrocarbon compounds whose commercial production started in the thirties and that have been widely used in the electro-technical industry. Although their production was stopped over 25 years ago, the Stockholm Convention included these compounds among the list of Persistent Organic Pollutants (POPs). In fact, humans continue to be exposed to the toxic effects of PCBs because of their resistance to chemical and biological decomposition, their capacity of bio-accumulation and their long half-life. Studies performed so far have pointed out a possible association between exposure to Polychlorinated Biphenyls and increased risk of developing some types of cancer (breast, prostate, testicular, ovarian and uterine cancers); it has also been suggested that these compounds may act as disruptive endocrine and cause infertility as well as other hormone-regulated disorders. PCBs accumulate in organisms through the food chain, and food is therefore the main exposure source for humans: it accounts for over 90% of exposure, the highest concentrations being found in fish (such as salmon and shellfish), dairy products (especially milk and butter) and animal fat. Moreover, waste-heaps, illegal disposal of oil waste and combustion of certain waste products in incineration plants represent sources of environmental pollution. The highest levels of PCBs in the environment were found in the early 1970s; since then concentrations of Polychlorinated Biphenyls have gradually decreased in all environmental components (water, air, earth and sediments), in fish, in other food products and lastly also in humans, thus suggesting that the associated risks have also likewise diminished.

RESUMO

The first studies conducted to evaluate a possible association between air pollution and mortality date back to the serious events that occurred in the Mosa Valley, Belgium (1930), in the small city of Donora ("killer fog" incident of 1948) and in London (1952). The latter episode led to the introduction of air pollution control policies. Following the introduction of air pollution control measures in economically advanced cities in the 60s and 70s, the concentration levels of pollutants reached were believed, for many years, to be risk free. However, despite improvements in air quality achieved by many industrialized countries the negative effects of air pollution remain today an important public health problem. Among all air pollutants, particulate matter is the type of air pollution that causes the most numerous and serious effects on human health, because of the broad range of diverse toxic substances it contains,. For this reason, when assessing human health risk, PM10 may be considered to be a reliable indicator of the impact of global air pollution. Various epidemiologic studies conducted in the last 10 years, such as the Air Pollution and Health-European Approach (APHEA) project, the National Morbidity, Mortality and Air Pollution (NMMAPS) Study and Italian Meta-analysis of Studies on the short-term effects of Air pollution (MISA), have shown that current ambient concentrations of PM10 may lead to increased mortality and morbidity. Various studies have reported mean increases in mortality below 1% for 10 ?g/mc increases of ambient PM10. Studies have also underscored the role of particulate matter in aggravating cardiorespiratory diseases and consequently increasing hospital admissions. Air quality standards have been recently revised by legislation. The EU has issued a directive that sets limiting values and, where appropriate, threshold values, for the different air pollutants.

RESUMO

No laws currently exist regarding the treatment of spa pool water, since it is not completely logical that these should have the same requirements as normal swimming pools. The problem arises especially with regards to the use of chlorine as a disinfectant, which may actually annulate the therapeutic effects of spring waters by altering their physical-chemical characteristics. Possible choices may be represented by frequent replacement of pool water, which may be easily achievable for small pools but more difficult to implement for larger pools, or by alternative disinfection methods such as ozone or ultraviolet rays. The efficacy of these methods must be shown through frequent chemical and microbiological analyses and future, to be hoped-for laws or guidelines, will need to be aimed at defining safety performance standards rather than prescribing analytical intervention and control methods. Beyond the choice of disinfection method, it is extremely important to highlight some relevant hygienic measures that bathers should take and that play a fundamental role in preventing infectious diseases which may be acquired in pools. The most important of these include: showering before entering the pool, wearing slippers around the pool, not urinating in the pool, not bathing if affected by diarrhea, wearing a bathing cap, avoiding the use of contact lenses while bathing and avoiding exchanging towels. Pool managers have the important role of avoiding overcrowding of the facilities and ensuring that all technological systems function properly.

RESUMO

Further research was performed on the disinfectant efficacy of peracetic acid on viruses. Hepatitis A virus (HM-175 strain), Poliovirus 2 (attenuated strain) and Coxsackie virus B5 (isolated strain) were tested using peracetic acid concentrations between 160 mg/l and 1280 mg/l. Inactivation tests were carried out at +20 degrees C and at 3 different pH conditions, acid, neutral and basic. The results confirmed that HAV virus, which showed a decline with concentrations above 320 mg/l, has the highest resistance with respect to the other viruses. The other two Enteroviruses were found to be less resistant, especially in neutral and acid conditions.

RESUMO

Chlorination by-products (CBPs) in drinking water have been associated with an increased risk of adverse pregnancy outcomes, including small for gestational age at term (term-SGA) and preterm delivery. Epidemiological evidence is weakened by a generally inaccurate exposure assessment, often at an ecological level. A case control study with incident cases was performed in nine Italian towns between October 1999 and September 2000. A total of 1,194 subjects were enrolled: 343 preterm births (26th-37th not completed week of pregnancy), 239 term-SGA (from 37th completed week, and weight less than the lowest 10th percentile) and 612 controls. Exposure was assessed both by applying a questionnaire on mothers' personal habits during pregnancy and by water sampling directly at mothers' homes. Levels of trihalomethanes (THMs) were low (median: 1.10 microg l(-1)), while chlorite and chlorate concentrations were relatively high (median: 216.5 microg l(-1) for chlorites and 76.5 microg l(-1) for chlorates). Preterm birth showed no association with CBPs, while term-SGA, when chlorite levels > or =200 microg l(-1) combined with low and high levels of inhalation exposure are considered, suggested a dose-response relationship (adjusted-Odds Ratios (ORs): 1.52, 95%CI: 0.91-2.54 and 1.70, 95%CI: 0.97-3.0, respectively). A weak association with high exposure levels of either THMs (> or =30 microg l(-1)), or chlorite or chlorate (> or =200 microg l(-1)) was also found (adjusted-OR: 1.38, 95%CI: 0.92-2.07). Chlorine dioxide treatment is widespread in Italy; therefore, chlorite levels should be regularly and carefully monitored and their potential effects on pregnancy further evaluated and better understood.

RESUMO

AIMS: To study the relationships between serum IGF-1, IGFBP-3 and IGFBP-2 and interleukin (IL)-1beta and IL-6 in inflammatory bowel disease (IBD). METHODS: Thirty-seven patients (18 males, 19 females, aged 8.8-26.1 years) with IBD (Crohn's disease, CD, n = 17, and ulcerative colitis, UC, n = 20) were studied. Patients were in relapse or remission according to established criteria. Serum IGF-1, IGFBP-3, IGFBP-2, IL-1beta and IL-6 levels were determined in patients and 15 healthy controls (aged 8.2-19.0 years). RESULTS: IGF-1 levels were lower in patients with CD in relapse compared with controls (p < 0.05). IGFBP-2 levels were higher in CD in relapse compared with other groups (all p < 0.05). In CD and UC patients (n = 37), IGF-1 levels were inversely correlated with the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). IGFBP-2 levels correlated positively with ESR and IL-1beta. IL-6 levels correlated positively with ESR and CRP. IL-1beta levels were elevated in CD in relapse compared to controls (p < 0.05) and were higher in UC in relapse than in other groups (all p < 0.05). In combined CD/UC patients in relapse (n = 20), IL-1beta levels were higher (p < 0.05) in patients with recto-sigmoiditis (n = 5) than in other patients. CONCLUSIONS: IGF-1, IGFBP-2 levels were related to IL levels, disease activity and anatomical distribution, consistent with active inflammation modifying the IGF-IGFBP system, possibly relevant to disturbance of growth.
