Summary: The anterior cruciate ligament (ACL) is the most commonly injured knee ligament. Currently there are two commonly used surgical procedures: middle third patellar tendon grafts (bone-patellar tendon-bone: BTB) and semitendinosus autografts or semitendinosus combined with gracilis tendon autografts (ST/G). Purpose. The aim of this study is to compare the rehabilitation results over time of amateur sportsmen who have undergone anterior cruciate ligament (ACL) reconstruction surgery by means of one of the two most commonly used procedures: middle third patellar tendon grafts (bone-patellar tendon-bone: BTB) and semitendinosus and gracilis tendon autografts (ST/G). Method. 30 subjects divided into two groups, (15 BTB and 15 ST / G), were evaluated during rehabilitation and at three follow-up periods (16 weeks, 24 weeks, 2 years). Evaluation involved clinical examination, isokinetic tests, and functional rating scales: Lysholm and IKDC. Results. The clinical evaluation resulted in the following mean values: the value of the Lysholm score was 78 in both group at 16 weeks, 91 in group A and 94 in group B at 24 weeks, 98 in group A and 99 in group B at 2 years; the value of the IKDC score was 14 in group A and 15 in group B at 16 weeks, 12 in group A and 14 in group B at 24 weeks, 14 in group A and 15 in group B at 2 years. No major complications occurred during rehabilatation Conclusions. Subjects in both groups showed good neoligament stability up to the 24-week follow up. At the 2-year follow-up the subjects of group B showed poor neoligament stability that prevented the return to the previous level of sporting activity; all the subjects with high intensity sports activity needed a greater muscle strengthening. No statistically significant differences between the two groups are seen., Competing Interests: The authors of this article have no conflict of interests to disclose., (Copyright© by GIMLE.)

HLA typing requests for association studies of immune-mediated diseases are often redundant and inadequate. We designed a series of meta-analyses to evaluate the accuracy of typing and distribution of HLA alleles predisposing to diseases, aiming at developing an app that can help doctors in choosing the most suitable molecular analysis. The first study was on celiac disease (CD) and HLA-DQ in children. We searched all english articles published in the main bibliographic databases up to May 2016. The search strategy has been developed using controlled terms (e.g. MeSH) and free terms. We identified 1885 articles. 1334 abstracts were examined. 46 manuscripts were evaluated, and 13 studies were included in the meta-analysis (740 CD and 943 controls). The risk of developing CD in children with allelic variants encoding the HLA-DQ2.5 and/or HLA-DQ8 molecules has been confirmed. The greatest CD risk resides in carriers of two DQ2.5 molecules, i.e. subjects homozygous for the DQB1*02:01 and DQA1*05 alleles (OR=5.4, 95 % CI=4.1-6.8) compared to any other DQ genotype. Carriers of two DQB1*02:01 (chain β2) alleles and one DQA1*05 (chain α5) allele have the same risk (p=0.8089) of DQ2.5 homozygotes (OR=5.3%, 95 CI=4,1 to 6.5). We found no differences between DQ8/β2 and DQ2.5/DQ8, nor between β2/DQX and DQ2.5/X. We suggest a two-step process: first typing the DQB1*02:01 allele and, in case of a negative result, full typing of HLA-DQ.

Balance and spatial orientation complaints, generically defined as "dizziness", are frequent in the elderly. They can cause a greater or lesser degree of handicap, and be associated with a greater or lesser degree of cognitive impairment and anxiety-depression symptoms. We examined 163 patients, referred for these complaints to the otoneurological outpatient services of 6 university hospital centres of the northern and central Italy, performing a bedside vestibular examination. The test allowed to distinguish between subjects with specific vestibular disorders (mainly BVP, Menière's disease and vestibular neuritis) and subjects in who the vestibular examination was not significant, and whose dizziness probably resulted from impairment or disease in multiple systems. The evaluation of the degree of handicap, using the Dizziness Handicap Inventory, showed that in the former group the physical parameters were significantly impaired with respect of a group of 81 age matched healthy controls, whereas the functional and emotional parameters were not. The evaluation of the degree of anxiety-depression, using the Hospital Anxiety Depression Scale, showed that all elderly people with balance and spatial orientation complaints present a degree of anxiety, but not of depression, greater than the controls, irrespective of the vestibular or extravestibular origin of the symptoms. The evaluation of the cognitive level, using the Mini Mental Test, showed that it is similar to the cognitive level in the controls when, according to the results of the otoneurological examination, the balance and spatial orientation complaints are due to vestibular disorders, but it is impaired when these symptoms are related to a dizziness of multifactorial aetiology. The presence of comorbidities is also higher in these patients. It is likely that in the elderly balance and spatial orientation complaints not caused by specific vestibular disorders are due to a dizziness of multifactorial origin, both organic and psychic, that can be classified as a geriatric syndrome.

Balance and spatial orientation complaints are very frequent in the elderly. The aetiology of these complaints may be related to specific peripheral or central vestibular disorders or to an extravestibular dizziness resulting from impairment or disease in multiple systems. A preliminary diagnostic orientation, permitting the patient to be referred to the most appropriate specialist (otologist, neurologist, consultant in internal medicine, psychiatrist, physical therapist) would be very useful. We examined 163 patients, referred for balance and spatial orientation complaints to the otoneurological outpatient services of 6 university hospital centres in the northern and central Italy, by a detailed questionnaire about characteristics, frequency, duration of any dizziness symptom and by a bedside vestibular examination. The questions were designed to determine whether the patients suffered from true vertigo, considered to be an expression of a vestibular disorder, or of an aspecific dizziness of multifactorial origin. Comparison of the conclusions of the vestibular examination and the diagnostic hypotheses deduced from the clinical history showed a high degree of concordance (Cohen Index 70.5%). To the patient, vertigo and dizziness are synonymous. By asking appropriate questions, a clearer picture should begin to emerge from the patient complaints so that distinction between psychogenic, nonvestibular and vestibular causes can be made. The importance of obtaining a good history cannot be overemphasized. A correct and rigorous approach by the general practitioner could be of great utility both for the health of the patient and for the efficiency of the national health service. The vestibular examination proved that about half the patients (80/163) suffered from vestibular disorders, mainly of peripheral origin (BPV, Menière's disease, vestibular neuritis).

Objective: To evaluate the efficacy of a program to control nosocomial spread of methicillin-resistant Staphylococcus aureus (MRSA)., Methods: Analysis of the incidence of infection and contamination due to MRSA in patients admitted to the hospital of Cremona 6 months before and 3 years after the introduction of the guidelines (July 1997)., Results: During the 42 months of the study period, on 80705 admissions, 511 cases of MRSA contamination/infection were identified, the incidence being 0.57 cases per 100 admissions. The infection rate dropped from 0.34 (IC95%: 0.25-0.45) in the first 6 months of the study, before the introduction of guidelines, to 0.17 (IC95%: 0.14-0.20) in the following 3 years (p=0.01). Severe infection decreased from 0.18 to 0.1 per 100 admissions, with a 44% decrease (p=0.058), while mild infections diminished from 0.16 to 0.07 per 100 admissions (p=0.045). Methicillin resistance among nosocomial isolates of Staphylococcus aureus was reduced from 53 % to 35 % (p<0.0001)., Conclusions: The introduction of a program to control the nosocomial spread of MRSA proved effective in reducing both the incidence of infection and the methicillin-resistance of Staphylococcus aureus isolates. The cost effectiveness of the program seems very favourable.

Purpose: We addressed the issue of the relationship between the general practitioner (GP) and the radiotherapist to improve the quality of care of cancer patients., Material and Methods: The study consisted in evaluating medical requests and phone interviews, with a questionnaire with yes/no and multiple choice answers to the following 5 questions: 1) Do you think a cancer diagnosis is always a hopeless death sentence? 2) Is it professionally rewarding to cure a cancer patient? 3) Are you satisfied with your relationship, as a general practitioner, with oncologic reference centers? 4) Is it more wearing for a general practitioner to manage a cancer than a noncancer patient? 5) Would you answer a questionnaire about the relationship between the general practitioner, the cancer patient and the oncologist? We evaluated 1590 medical requests and made 401 phone interviews; 255 colleagues (70%) answered the questionnaire., Results: Medical requests were correctly and completely formulated by GPs in 45% of cases. A cancer diagnosis was not considered a hopeless death sentence in 90.9% of cases and 76% of GPs considered it professionally rewarding to cure a cancer patient. 75.6% of GPs considered it more wearing to manage a cancer than a noncancer patient, and female GPs felt this more strongly than their male counterparts. Irrespective of gender, GPs over 50 years of age tend to consider cancer a hopeless and fatal disease. The relationship with oncologic centers was considered satisfactory in 86.2% of cases. However, since cancer patients need greater medical care, GPs would like a closer cooperation with oncologists., Discussion and Conclusions: The great interest GPs took in this study encourages further investigation through a more in depth questionnaire designed with the help of GPs themselves and interested statisticians.

Introduction: Calcification of the ductus and ligamentum Botalli with no cardio-respiratory symptoms is normally a sign of their closure. However, as the calcification can be associated with a patent duct or a ductal aneurysm, its presence must not be misinterpreted. The frequency and the different patterns of this calcification must be known, as well as is diagnostic relevance. It is also important to differentiate it from other types of upper mediastinal calcification., Material and Methods: Thirty-two cases of ducts Botalli calcification were collected over 16 years, during which time period 38,476 children (24,095 males, 14,381 females) were submitted to chest radiography. Patient populations were divided into the following age-groups: preterms-newborns; 2-3 months; 4-6 months; 7-12 months; 2-3 years; 4-6 years; 7-10 years; 11 years on. We studied the ductus Botalli according to the following parameters; conspicuity, location, size and shape of the calcification; prevalence of the radiographic finding in 1,000 patients by gender and age; persistence of the finding in follow-up examinations., Results: The calcification was found in left mediastinal site at the posterior aspect of the 4-6th ribs, ranging 1-6 mm in length, and 1-4 mm in width. It had a round, comma-like or elongated shape. In all, 32 cases of ductal calcification (.83/1000) were found: 14 (44%) were in males (age range 7 months-12 years), 18 (56%) in females (age range 11 months-10 years). Age range analysis shows that the calcification is distributed more evenly in the male population with the highest number of calcified ducts (5 = 94/1000) found in the 4-6 year age group and a relative prevalence in the age group 7-12 months (2 cases = 1.05/1000). A marked prevalence is found in females 4-6 years old (11 cases = 3.8/1000). The duct calcification was an occasional finding during chest radiography for other, more severe conditions in 9 of 14 males and in 6 of 18 females., Conclusions: No data can be found in the literature on the frequency of ductus Botalli calcification at chest radiography: our results indicate it to be less than 1/1000 (.83/1000). We have found a prevalence of ductus calcification (1.25/1000) in females even though females are less numerous in our population. The ductal calcification is often associated with severe, mostly hematologic, diseases. We believe that the conspicuity of the calcification is due to its density more than to its shape and size. Literature data indicate that ductus calcification may still be visible 6 months to 8 years after its discovery: our results, although on a small series, confirm this observation. The clinical significance of the calcification is still unclear.

In recent years the management and interdisciplinary treatment of oncological patients has become extremely complex due to the progress made in diagnosis and therapy. As a result, the knowledge required to treat patients can no longer be simply memorized or manually filed. Computer technology provides the ideal instrument for organizing, saving and analyzing data from head and neck tumor patients. The authors have prepared a computerized database to meet the following needs: ease of use, even for non computer savvy users; minimal ambiguity for data entry; use for both clinical and scientific purposes; possibility to create a network with similar database at other Centers; possibility to expand to include image management. The archive is based on a personal computer with an INTEL 80486 microprocessor, 40 Mb RAM, DOS 6.0. and Windows 3.1. The software includes four main routines: a) formulation and management of tables where oncological data are gathered; b) entry and management of patient-related clinical data; c) statistical processing for epidemiological and oncological research and; d) management of basic computer services. In clinical practice the database allows the following: a) preparation of a monthly chart of check-ups, b) rapid tracking of patients lost to followup, c) printout of a summary of the clinical history of each patient at the time of check-up and rapid updating at the end of the examination, d) automatic production of forms such as discharge letters and reports to be shared with related services (i.e. medical oncology, radiotherapy). In addition, the database is a powerful, versatile research tool which can promptly provide all sorts of oncological data and can automatically prepare tables, diagrams, correlations, survival curves. The system was developed from 1993 to 1995 and has been operative, with a few minor modifications and updates, since 1995. Today the database contains more than 1200 oncological cases and the system is used daily by medical and paramedical personnel alike. Approximately 15 new cases are entered a month and 80 cases updated after follow-up.

Background: The decreased availability of economic resources, opposed to the increased demand for medical assistance, requires the use of methods to assess hospital efficiency. Purpose of our study was to evaluate and quantify the "products" of a cardiology department, as well as the changes in time of their production, by means of a catalogue of medical acts, set up for the French health system (CdAM)., Methods: The study includes the 224 admissions occurring in October 1987 and the 209 admissions of October 1992. Medical acts were recorded for all admissions, by number of acts as well as by weight of acts; this weight (expressed as complexity/cost index or ICR) takes into account the use of resources in terms of medical staff and nursing staff, together with technical resources, for each act. In 1987 and 1992, 1736 and 1603 acts were performed respectively, corresponding to a total weight of 24308 and 32194 ICR., Results: The increased ICR appears to be related to an increase of invasive procedures, particularly of interventional electrophysiology and haemodynamics. By considering case mix, we observed an increment of ICR for the diagnosis of angina (from 194.3 to 227.4 ICR per patient), of arrhythmias (from 178.0 to 273.1) and of cardiomyopathy (from 95.6 to 179.7)., Conclusions: In conclusion, CdAM allows to evaluate the cardiologic activity also in the Italian situation; the ICR of each act permits to estimate the human and technical burden, with subsequent easy internal and external comparisons.

The article verifies health's state and style of life of the goldsmith people of the USSL n. 71-Valenza Po. The study, executed in the 1989 year, consisted in the distribution of a autowriting questionnaire to 565 goldsmith who are working for the majority in small factory. Questionnaire's analysis showed the young age of workers and the big experience in specific duty. The diseases of locomotor district are represented with great differences respect data of italian population. These data are plausibility induced with the postural vices during working activity. Other pathologies relevant are contact dermatitis, chronic bronchitis, bronchial asthma and optic disturb. The results of the study had induced the Authors to organize new and over deepened epidemiological studies to investigate disturbs of visus and locomotor district.

A descriptive epidemiology study carried out with the purpose of assessing the incidence of malignant bladder cancer in the province of Vercelli is reported. 833 hospitalised cases were observed in the period 1972-1981. Incidence rates were calculated on the resident population at the date of the last two national censuses. Sex, patient age and distribution in the three areas into which the province is subdivided are illustrated and discussed and trend in incidence rates in the two five-year periods 1972-1976 and 1977-1981 reported. The standardised rates are compared with those of the provinces of Turin and Varese.
