Paediatricians' attitudes toward pain in children with severe cognitive impairment. A regional survey.

INTRODUCTION: pain is a frequent and relevant problem in children with severe cognitive impairments. Assessing pain in these patients can be difficult. Specific observational tools such as the Collignon Giusiano Questionnaire or the Non-communicating Children's Pain Checklist ( NCCPC) are available, but their use is not widespread. Children with severe cognitive impairment are frequently in need of painful procedures but data about availability of procedural sedation in this setting are limited. OBJECTIVE OF THE STUDY: to evaluate paediatricians' attitudes toward pain in children with severe cognitive impairment by measuring the use of specific pain scales and the use of analgesia or procedural sedation in course of a frequent procedure such as botulinum toxin injection. METHODS: phone interview with the doctor on duty of 56 paediatric wards in 3 regions of the North East of Italy, addressing the routine use of pain scales, and the use of specific observational tools for non communicating children. A phone interview was also conducted in 4 centers routinely practicing botulinum toxin injection about the use of analgesia or procedural sedation. RESULTS: 1 centre out of 55 reported to use specific scales for children with cognitive impairment, specifically the Collignon Giusiano Questionnaire. No centre used procedural sedation for botulinum toxin injection. CONCLUSION: in the investigated area there is a lack of attention to pain in children with severe cognitive impairment. Specific educational efforts should be done to improve the quality of care in this setting.

A geo-chemo-mechanical study of a highly polluted marine system (Taranto, Italy) for the enhancement of the conceptual site model.

The paper presents the results of the analysis of the geo-chemo-mechanical data gathered through an innovative multidisciplinary investigation campaign in the Mar Piccolo basin, a heavily polluted marine bay aside the town of Taranto (Southern Italy). The basin is part of an area declared at high environmental risk by the Italian government. The cutting-edge approach to the environmental characterization of the site was promoted by the Special Commissioner for urgent measures of reclamation, environmental improvements and redevelopment of Taranto and involved experts from several research fields, who cooperated to gather a new insight into the origin, distribution, mobility and fate of the contaminants within the basin. The investigation campaign was designed to implement advanced research methodologies and testing strategies. Differently from traditional investigation campaigns, aimed solely at the assessment of the contamination state within sediments lying in the top layers, the new campaign provided an interpretation of the geo-chemo-mechanical properties and state of the sediments forming the deposit at the seafloor. The integrated, multidisciplinary and holistic approach, that considered geotechnical engineering, electrical and electronical engineering, geological, sedimentological, mineralogical, hydraulic engineering, hydrological, chemical, geochemical, biological fields, supported a comprehensive understanding of the influence of the contamination on the hydro-mechanical properties of the sediments, which need to be accounted for in the selection and design of the risk mitigation measures. The findings of the research represent the input ingredients of the conceptual model of the site, premise to model the evolutionary contamination scenarios within the basin, of guidance for the environmental risk management. The study testifies the importance of the cooperative approach among researchers of different fields to fulfil the interpretation of complex polluted eco-systems.

Rapid improvement of symptomatology with pantoprazole, amoxycillin and metronidazole in Helicobacter pylori-positive duodenal ulcer patients.

BACKGROUND/AIMS: To evaluate the efficacy and tolerability of a new 1-week triple therapy regimen consisting of pantoprazole, amoxycillin and metronidazole. METHODOLOGY: The study involved 51 Helicobacter pylori (H. pylori) positive patients (M:30, F:21, mean age: 52.5 years, range: 24-75) affected with duodenal ulcer in active phase. At baseline and 6 weeks after the completion of treatment, clinical assessment, endoscopy with gastric biopsies, rapid urease test, 13C urea breath test, and serum laboratory analyses were performed. All patients were treated with pantoprazole 40 mg once daily, plus amoxycillin 1 gram tid and metronidazole 250 mg tid for 1 week, and pantoprazole 40 mg once daily for a second week. A clinical diary for daily assessment of symptoms and side effects was completed by patients during the treatment period. RESULTS: Three patients were discontinued from the study. Six weeks after therapy, the ulcer was healed in 47 of 48 patients (97.9%, 95% CI = 93.9-100). The cure rates of H. pylori infection, expressed using both the intention-to-treat and per protocol analyses, were 80.4% (95% CI = 69.5-91.3) and 85.4% (95% CI = 75.4-95.4), respectively. The therapy led to a significant, rapid disappearance or reduction in daytime epigastric pain, from 68.8% on day 1 to 82.2% on day 3 (p < 0.001) and in nocturnal epigastric pain, from 80.6% on day 1 to 93.3% on day 3 (p < 0.001). After 2 weeks of treatment, the percentage of patients completely free of pain was 82.2% for daytime pain and 90.3% for nocturnal pain. A rapid improvement in acid regurgitation, heartburn, nausea and vomiting was also observed with a median value of symptom disappearance of 2 days. The percentages of patients completely symptom-free were 37.5% after 1 day, 54.1% after 3 days, 75% after 2 weeks, and 83.3% after 2 months. H. pylori-cured patients showed a significant decrease in the histological activity of both antral (p = 0.0001) and body (p < 0.008) gastritis. Mild to moderate adverse events were reported by 15 patients. CONCLUSIONS: One week triple therapy with pantoprazole in combination with amoxycillin and metronidazole, followed by a second week of pantoprazole, was well tolerated and highly effective for the 1) rapid improvement or resolution of symptoms; 2) healing of the DU; 3) eradication of H. pylori infection; and, 4) reduction of histological signs of chronic gastritis activity.

[Effects of cyclosporin A on various indices of cholestasis in kidney transplant recipients]. / Effetti della ciclosporina A su alcuni indici di colestasi nei trapiantati renali.

A cholestatic syndrome has been reported as one of the main side effects of CyA therapy. The aim of the present study was to evaluate frequency and degree of severity of the cholestatic syndrome in a group of patients with renal transplant treated with CyA. In 55 patients we evaluated both clinical: jaundice, pruritus, presence of biliary lithiasis and biochemical parameters: total serum biliary salts (TBS), total bilirubin (TB), alkaline phosphatase (AP), gammaglutamyl transpeptidase (GGT), transaminase (AST, ALT), cholesterol (CT), triglycerides (TG), HDL-cholesterol (HDL-C) and compared them with a control group matched for sex and age. In the transplant patients significantly higher values of TBS, TB, AP (p < 0.05) were found; 55% of the patients had above mean values of at least one of the classical parameters of liver function and an higher frequency of biliary lithiasis was also found, in the absence of the classical risk factors. However, none of the patients presented severe signs of hepatic disease and to date it has never been necessary to stop treatment. In conclusion, our study shows that the dosage of CyA used at present is quite safe; however, it is necessary to monitor in these patients some parameters of liver function to prevent the minor side effects we observed from progressing into more serious damage.

[Therapy of resistant duodenal ulcer]. / Terapia dell'ulcera duodenale resistente.

Significant progress has been made in the treatment of duodenal ulcers since cimetidine went on the market. Furthermore widespread use of the H2 blockers has enable us to identify a group of patients who take 8-12 weeks to heal, despite effective treatment and who are now known as "slow" or non-responders. In tackling the problem of ulcers resistant to medical treatment, the paper details the possibilities offered by current solutions on the basis of personal experience as well as reports in the literature. The results obtainable by surgery are also assessed with emphasis on the identification of suitable patients for and the appropriate timing of his surgical option. Finally a therapeutic flow-chart providing guidelines for the rational selection of therapeutic strategies that still had to be based on uncodified personal preferences is proposed.

[Role of endoscopy in lymphomatous pathology of the digestive tract]. / Il ruolo dell'endoscopia nella patologia linfomatosa del tubo digerente.

Increasingly frequent reports of lymphoma with a gastro-intestinal primary location have stimulated much interest. Symptomatology has been shown not to be very specific, and scarcely different to that of other gastro-intestinal pathologics, both benign and malignant. The identification of some endoscopic pictures which suggest a lymphomatosic pathology and the possibility of collecting targeted biopsy samples, have placed endoscopy among the most important tests in the diagnostic and staging phase of gastro-intestinal lymphoma. This technique plays an equally important role in the follow-up period, since it allows the therapeutic efficacy of treatment to be assessed and the early identification of possible relapses.

[Prevalence of biliary lithiasis in chronic liver disease]. / Prevalenza della litiasi biliare in epatopatici cronici.

The prevalence of cholelithiasis was determined by ultrasound in 168 patients affected by chronic liver disease and compared to 828 subjects of the general population. We found an increase of cholelithiasis in chronic liver patients (p less than 0.004). This difference persisted separating the subjects in males (p less than 0.003) but not in females (p less than 0.08). Examined by age groups, patients demonstrated, like in the control group, an increase of frequency with the increase in age. We did not find any association with BMI, cholesterolemia, triglyceridemia, albuminemia and gammaglobulinemia levels. A significant association was found in the total (p less than 0.003) and indirect (p less than 0.0001) bilirubinemia. Finally, there was no significant association with the etiology of the liver disease. Even though there was a greater association with alcoholic and cryptogenetic liver disease.

[Ursodeoxycholic acid for the treatment of chronic diseases of the liver. Short-term results]. / L'acido ursodesossicolico nel trattamento delle malattie croniche di fegato. Risultati a breve termine.

The tolerance and the effect of ursodehoxycholic acid (UDCA) on the level of transaminases and gammaglutamyl-transpeptidase (GGT) has been estimated, over the short term, in 27 patients affected by compensated liver cirrhosis in comparison to 24 patients, representing the control group. The results were good with regard to GGT values, as a meaningful reduction was observed during the first month of therapy which then improved in the next five months. There was also a significant reduction in transaminase levels at the end of the second month of therapy, which was maintained until treatment was stopped; mean values however were not within the normal range. These results, together with tolerance of the drug confirm a role of UDCA in the treatment of chronic liver diseases in an advanced stage.

Basal ganglia calcifications and ALS syndrome.

We report the case of a patient with idiopathic hypoparathyroidism and unusually large symmetrical calcifications in the basal ganglia, thalami, cerebellar hemispheres and brainstem, who clinically presented an ALS-like syndrome. We discuss the possible role of abnormal calcium metabolism in the pathogenesis of motoneuron disease.

The stomach in liver cirrhosis. Endoscopic, morphological, and clinical correlations.

The stomachs of cirrhotic patients are frequently subject to a number of alterations, detectable by endoscopy, the presence of which indicates a disturbance in the mucosa. Several investigators believe that portal hypertension plays an etiopathogenetic role. Three groups of subjects were studied prospectively: 83 cirrhotic patients with portal hypertension, 53 cirrhotic patients without portal hypertension, and 135 control subjects. Snake skin, scarlatina rash, and petechia were the most frequent endoscopic findings in the cirrhotic patients with portal hypertension (P less than 0.001); these findings were also most frequently present in association with each other in this group. There was no correlation between the endoscopic findings, the clinical gravity of liver cirrhosis (Child-Pugh grade), and the gravity of esophageal varices (Beppu score). There were no characteristic inflammatory findings in the gastric mucosa. Hypergastrinemia was often observed in cirrhotic patients with and without angiodysplasias.

The duodenum in liver cirrhosis: endoscopic, morphological and clinical findings.

Endoscopic studies were performed to determine whether changes occurred in the duodenum related to portal hypertension in patients with liver cirrhosis. The total of 271 patients studied were subdivided into three groups: 83 patients with liver cirrhosis and portal hypertension, 53 with liver cirrhosis but no portal hypertension, and 135 controls. In the duodenum of cirrhotic patients with portal hypertension several changes were observed on endoscopy that were also present in the other two groups. Atrophy and vascular malformations, however, were present only in the duodenum of cirrhotic patients with portal hypertension, although in only a few patients and with statistical significance only for vascular malformations (p less than 0.01, phi = 0.21). Eleven percent of the patients had more than one endoscopic finding, but the associations of findings were without statistical significance. No statistically significant correlation was observed between the clinical severity of cirrhosis or the severity of esophageal varices and the endoscopic findings. Finally, there was no statistically significant difference between the histological findings of duodenitis in the three groups of patients.
