RESUMO
A contact investigation following a case of infectious tuberculosis (TB) reported in a call centre in Milan (Italy) led to the identification of three additional cases that had occurred in employees of the same workplace during the previous 5 years, one of whom was the probable source case. Thirty-three latent infections were also identified. At the time of diagnosis, the source case, because of fear of stigma related to TB, claimed to be unemployed and a contact investigation was not performed in the workplace. Cases were linked through genotyping of Mycobacterium tuberculosis. TB stigma has been described frequently, mainly in high-incidence settings, and is known to influence health-seeking behaviours and treatment adherence. The findings in this report highlight that TB-associated stigma may also lead to incomplete contact investigations. Little is known about the causes and impact of TB-related stigma in low-incidence countries and this warrants further exploration. Research is also needed to evaluate the effectiveness of specific interviewing techniques and training interventions for staff in reducing feelings of stigma in TB patients. Finally, the outbreak emphasizes the importance of integrating routine contact investigations with genotyping.

We describe a foodborne outbreak in Italy caused by enteroinvasive Escherichia coli (EIEC), an enteric pathogen uncommon in industrialized countries. On 14 April 2012 a number of employees of the city of Milan Fire Brigade (FB) were admitted to hospital with severe diarrhoea after attending their canteen. Thirty-two patients were hospitalized and a total of 109 cases were identified. A case-control study conducted on 83 cases and 32 controls attending the canteen without having symptoms identified cooked vegetables to be significantly associated with the disease. Stool samples collected from 62 subjects were screened for enteric pathogens using PCR-based commercial kits: 17 cases and two asymptomatic kitchen-workers were positive for the Shigella marker gene ipaH; an ipaH-positive EIEC strain O96:H19 was isolated from six cases. EIEC may cause serious dysentery-like outbreaks even in Western European countries. Microbiologists should be aware of microbiological procedures to detect EIEC, to be applied especially when no common enteric pathogens are identified.

INTRODUCTION: The authors report their experience about the intraoperative manometry in the achalasia surgical treatment. PATIENTS AND METHODS: We have considered 239 patients with achalasia observed from 1994 to 2006; only 79 continued the path diagnostic therapeutic and 31 underwent Heller longitudinal miotomy, with Dor anti-reflux plastic in 25 patients and in 6 Nissen anti-reflux plastic. In 24 we performed the intraoperative manometry (MI) recording the high pressure areas. RESULTS: The patients underwent Heller's procedure with manometric check of the gastric muscular fibre sectioned areas reported the disappearance of the dysphagia. Three of the operated ones without using the MI complained about the persistence of mild dysphagia and it did not depend from the antireflux surgical procedure used. CONCLUSIONS: Our findings confirm that the extramucosal miotomy is the treatment of choice for the achalasia and suggest that by MI a complete miotomy is allowed mostly on the gastric side where the muscular fibres get an important role in the maintenance of the high pressure areas.

INTRODUCTION: Starting from the observation of 9 cases of giant infected pancreatic cysts, which occurred from 1994 to 2004 at the Department of Oncological and Surgical Studies, the Authors' aim has been to evaluate whether a more thorough necrosectomy, carried-out under video-endoscopic control, associated with a nose-gastro-cavity tube, which ensures a continuous cleansing of the newly-formed cavity, and an appropriate positioning of the drainages, could reduce the morbidity and allow a shorter recovery of the infected pseudocysts. PATIENTS AND METHODS: Of 73 cases of acute pancreatitis, observed from 1994 to 2004, 9 showed severe and acute pancreatitis, which included giant pseudocysts, as revealed by the abdomen angio-TC. Our nine septic patients underwent cysto-gastro-anastomosis, necrosectomy, intraoperative cleansing of the cavity with an antibiotic solution and positioning of multiple drainages. Three of these patients also underwent a thorough and targeted necrosectomy, assisted by a trans-anastomotic video-endoscopy. A nose-gastro-cavity tube has been placed in all the patients. RESULTS: The disappearance of the septic state in our three patients who underwent a targeted video-assisted necrosectomy occurred after three days of treatment; moreover, the abdomen angio-TC on the 5th postoperative day showed the disappearance of the necrotic areas. The recovery of these three patients was significantly shorter, compared to those undergoing traditional treatment (cysto-gastro-anastomosis, standard necrosectomy and positioning of abdominal drainages). CONCLUSIONS: Our surgical video-assisted technique demonstrated that, with a slight increase in the operative time, a better control over sepsis may be accomplished, as well as a reduction of the post-operative morbidity, which leads to shorter hospitalisation of patients with infected pancreatic pseudocysts.

The prevalence of Escherichia coli among the uropathogens routinely isolated in non-hospital laboratories (Labs) and its susceptibility profiles were investigated. Thirty-three Labs were selected throughout Italy. In vitro assays were performed by means of disk diffusion according to the CLSI. Females were prevalent (79.9%) and the mean patient age was 58.6 (sd 20.4) years. Overall, the prevalence of E. coli was 55.3% (1375 strains), with Enterococcus spp 10.2 %, Proteus mirabilis 4.8%, coagulase-negative staphylococci 4.3% and Klebsiella 3.8% being the next most frequently encountered species. High compliance with quality control program was observed. Susceptibility figures in E. coli were consistently low for many antimicrobial agents such as ampicillin (51.3%) and co-trimoxazole (74.6%) and higher for others such as gentamicin (87.9%) and ceftazidime (95.1%). Resistance rates were higher among male patients and increased according to the patient's age.

The authors present a case of gallstone intermittent ileus caused by the passage of a big gallstone (about 4 cm in diameter) in the intestinal lumen, through a cholecystoduodenal fistula. They emphasize the peculiarity of the case for the characteristics of symptoms and for casual diagnostic check-up with a ultrasonography. The disease is not frequently diagnosed; today it has a safe recognition by modern imaging. The symptoms can be intermittent and, even when there are the classic signs of intestinal occlusion, the site of the occlusion is various. With a timely endoscopical or surgical approach (open or laparoscopic) it is possible to reduce mortality of patients treated in emergency.

Old age cannot be considered as an absolute risk factor in the surgical treatment of inguinal hernia, which can also be stated for the majority of elderly people pathologies. The opportunity of surgically treating a wider range of individuals has been made possible thanks to the use of both modern, less invasive surgical techniques and easy-to-handle anaesthetic medicines, as well as a new concept of elderly-customer-friendly sanitary planning. The evaluation of the risks is multifactorial; consequently, in the case of elderly cardiopath individuals, suffering from inguinal hernia, one has to reconsider both the type of anaesthetic and the surgical technique to be performed, in view of the increased risks, as against the case of non cardiopath, elderly patients. The modern tension-free techniques have demonstrated in cardiopath patients the same advantages which have been observed in elderly non cardiopath patients, such as a faster functional recuperation as well as no significant percentage difference related to the early and late complications following the operation.

The Authors, on the basis of a case of giant spleen cyst with positive tumoral markers, analyse some epidemiological and clinical aspects related to splenic non parasitic cysts. They affirm the priority of the conservative surgery, whenever possible, followed by an appropriate follow-up, although in this case their therapeutic choice was radical, due to the lack of residual parenchyma. In accordance with the data of several publications, as well as on the basis of the results obtained, the conservative approaches have been reevaluated, above all in view of the modern findings related to the function of the spleen. The conservative approach cannot be carried out in the following cases: neoplastic diseases, increase of the tumoral markers serum levels, total involvement of the splenic parenchyma by cysts.

In the last years, the introduction and employment in surgery of the dissectors of last generation (ultrasounds, radiofrequency, etc.) have contributed to a remarkable improvement and simplification of the performances and the surgical techniques. The present study has the aim to verify, on the basis of the experience made in the last two years and through a careful comparisons with operations performed in the usual way, the advantages of employment of ultrasonic dissector in thyroid surgery and if besides such advantages it is possible to obtain real and substantial reductions of the complications. To such aim a randomized perspective study has been lead, confronting two groups of 60 patients, submitted to total thyroidectomy in Chair of General Surgery and Surgical Physiopathology of the University of Palermo-Complex Operating Unit of General Surgery. In all patients have been considered age, sex, histological diagnosis, length of the incision, time (from the incision until suture of skin), entity of the bleeding, hospital stay, post-operative consequences and total costs of thyroidectomy. The elaboration of the obtained data shows the advantages following to the use of the dissectors of last generation: reduction of the times, reduction of the complications, better tolerance of the operation by patients, better rationalization of the resources.

Cerebral cavernous malformations (CCMs) are vascular abnormalities that may cause seizures, headaches, intracerebral hemorrhages, and focal neurological deficits; they can also be clinically silent and occur as a sporadic or an autosomal dominant condition. Three genes have been identified as causing familial CCM: KRIT1/CCM1, MGC4607/CCM2, and PDCD10/CCM3, mapping, respectively, on chromosomes 7q, 7p, and 3q. Here, we report an Italian family affected by CCM due to a MGC4607 gene mutation, on exon 4. All the affected subjects suffered from seizures, and some of them underwent surgery for removal of a cavernous angioma. Brain MRI showed multiple lesions consistent with CCMs in all patients. Spinal and cutaneous cavernous angiomas were present too. This report underlines the need for a careful interdisciplinarity among neurologists, neuroradiologists, neurosurgeons, geneticists, ophthalmologists, and dermatologists for a total evaluation of the different manifestations of familial CCM. This points out that only referral centers are organized to offer a multidisciplinary management of this disease.

This is the first report of a severe case of Mycobacterium chelonae keratitis; it occurred in a 26-year-old man after he had undergone excimer laser photorefractive keratectomy for the correction of severe myopia, once the epithelium was already healed. The diagnosis was made by culture results and acid-fast staining of corneal scrapings. Topical ciprofloxacin sodium, 0.3 mg/mL, plus amikacin sodium, 10 mg/mL, and oral clarithromycin sodium led to remission of the ulceration after 3 months of therapy. Subsequent topical corticosteroid therapy led to complete visual recovery during 1 year of follow-up. There may be an increased risk of severe keratitis during the first postoperative months in eyes that have already undergone photorefractive keratectomy, due to the presence of some microepithelial defects symptomatically negative and not easily detectable by slit-lamp examination.

MB-Redox is a new manual culture system designed for the recovery of mycobacteria from clinical specimens. It consists of a liquid medium (modified Kirchner medium) containing a redox indicator, a colorless tetrazolium salt, which is reduced to colored formazan by actively growing mycobacteria. Acid fast bacilli (AFB) are easily detected in the medium as pink to purple pinhead-sized particles. We report the results of a multicenter study (involving four Italian microbiology laboratories processing 2370 clinical specimens) aiming to evaluate the recovery rates of AFB and time required for their detection by using the MB-Redox medium. Two different protocols were set up: in Protocol A (1580 specimens) the performance of MB-Redox was compared with those of the radiometric BACTEC 460 TB system (B460) and Löwenstein-Jensen medium (L-J), whereas in Protocol B (790 specimens) it was compared with those of the Mycobacteria Growth Indicator Tube (MGIT) and L-J. A total of 213 mycobacteria were recovered, including 172 Mycobacterium tuberculosis complex (MTB) isolates and 41 nontuberculous mycobacteria (NTM) isolates. In Protocol A, recovery rates were 81% for MB-Redox system, 84% for B460 system, and 77% for L-J. In Protocol B the recovery rates by individual system were 87, 83, and 76% for MB-Redox, MGIT, and L-J, respectively. Differences in both the protocols were not statistically significant. The MB-Redox system plus L-J (Combination 1) recovered 94% of the isolates in Protocol A and 93% in Protocol B, while B460 plus L-J (Combination 2) and MGIT plus L-J (Combination 3) detected 91 and 89% of all mycobacteria isolates respectively. No statistically significant differences were found among the combinations. The mean time to detection of mycobacteria was 16.3 days in Protocol A and 19.1 days in Protocol B with the MB-Redox system, 22.4 and 25.9 days with L-J, 13.2 days with B460, and 18.2 days with MGIT. The contamination rates were 2.1, 2.0, 1.9, and 3.6 for MB-Redox, B460, MGIT, and L-J respectively. The MB-Redox is a reliable, nonradiometric system for growth and detection of mycobacteria. When used in combination with a solid medium it proved to be an effective replacement for B460. The MB Redox system is a labor-intensive method requiring much handling during the visual reading procedures.

OBJECTIVE: To assess the ability of 59 clinical microbiology laboratories distributed throughout Italy to correctly identify and detect reduced susceptibility to glycopeptides in staphylococci and VanA-, VanB- or VanC-mediated glycopeptide resistance in enterococci. METHODS: Eight test strains comprising three staphylococci (S. aureus ATCC 29212 and two vancomycin-intermediate S. haemolyticus [11105301, 10030683Y]) and five enterococci (E. faecalis ATCC 29212, E. faecalis ATCC 51299 VanB, E. faecium AIB40 VanA, E. faecalis V583 VanB and E. gallinarum AIB39 VanC1) were distributed to 59 Italian clinical microbiology laboratories. Each isolate was blind-coded, and laboratories were instructed to identify the strains and test isolates for susceptibility to teicoplanin and vancomycin using their standard methods. Results were assessed against consensus test results obtained by a reference laboratory. In addition, to complement data interpretation, laboratories were asked to provide retrospective routine test results from their respective hospitals. RESULTS: All 59 laboratories participating in the study completed the susceptibility testing and provided data for analysis. A total of 53 laboratories provided retrospective routine data. Overall, laboratories were able to identify isolates to the genus level successfully. E. gallinarum and S. haemolyticus posed problems for species identification, with only 40.6 and 71.2%, respectively, of results reported correctly; most incorrect results were reported as 'other species'. For enterococcal test strains, VanA phenotypes were detected correctly by 96.6% of laboratories; VanB by 30.5% (E. faecalis ATCC 51299) and 88.1% (E. faecalis V583); and VanC1 by 67.8%. For staphylococcal test strains, 28.8% (S. haemolyticus 11105301) and 23.7% (S. haemolyticus 10030683Y) of the laboratories were able to detect reduced susceptibility to vancomycin. Errors in detecting vancomycin resistance in VanB and VanC1 enterococci were made with all methods, most noticeably by disk diffusion users. For staphylococci, most errors in reporting vancomycin-intermediate resistance occurred with disk diffusion and Vitek (software version 5.04) users. Overall, considerably fewer errors occurred with the detection of teicoplanin resistance, especially for staphylococci. For 1999, routine results show that 41/1749 (2.4%) of E. faecium, 220/11 180 (2.0%) of E. faecalis, 29/24 927 (0.12%) of S. aureus and 54/22 102 (0.24%) of coagulase-negative staphylococci were reported as resistant to vancomycin. CONCLUSION: Italian laboratories are able to identify staphylococci and enterococci adequately, although all methodologies used have problems in identifying E. gallinarum and coagulase-negative staphylococci to the species level. While VanA phenotypes were efficiently detected, problems were experienced in detecting VanB and VanC phenotypes. The majority of laboratories were unable to detect reduced vancomycin susceptibility in staphylococci adequately, especially with disk diffusion and older Vitek systems. Teicoplanin appeared useful as a marker for detecting vancomycin resistance, particularly with disk diffusion. Should enterococcal VanB or staphylococcal glycopeptide-intermediate phenotypes become prevalent in Italy, it is likely that they would be under-detected. New systems under development, such as Vitek2, should improve this situation.

We report on a case, ulcerative colitis and another of Crohn's disease. During a relapse which was unresponsive to conventional therapy, acid-fast bacilli were found in colonic biopsies. Conventional therapy was substituted with antimycobacterial chemotherapy (rifampicin, isoniazid and ethambutol) which was responsible for a marked improvement. However, a relapse occurred during chemotherapy and no acid-fast bacilli were found. The patients became responsive to sulphasalazine and corticosteroid therapy once again. It appears that Mycobacteria play a collateral role in inflammatory bowel disease and that once they have been eliminated the original disease re-emerges.

Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) profiles of bacterial proteins have been successfully used for taxonomical purposes. More recently this technique has been applied to epidemiological investigations in respect of various micro-organisms including Neisseria meningitidis, Staphylococcus aureus and Clostridium difficile. The main limitations of the methods so far described are lack of standardisation in extraction and separation as well as in the analysis of results. Although reproducibility in the same laboratory has been shown to be satisfactory, comparison of results among laboratories is still difficult. Moreover, assessment of differences and/or similarities among chromatograms or autoradiographs showing many bands depends upon qualitative descriptions. Interpretation of densitometric scannings is laborious and time-consuming. In this paper we present our experience of a completely standardised, fully computer-controlled procedure for SDS-PAGE (AMBIS System) in analysing 35S-methionine-labelled total proteins. The methodology proved very useful in monitoring a hospital outbreak of Serratia marcescens. It allowed us to make quantitative comparison in a shorter time as well as to handle easily a great amount of data and usefully integrate it with those obtained with other systems such as serotyping. Furthermore, when the two systems are used together, more precise information can be gained. In this epidemic, serotyping indicated the presence of two groups which would have been missed by PAGE analysis alone. Electrophoretotyping, however, focused on similarities of cellular proteins among the epidemic strains. This allowed us to distinguish them from epidemiologically unrelated strains of the same serogroup.(ABSTRACT TRUNCATED AT 250 WORDS)

BACKGROUND: According to Italian Law, second trimester termination of pregnancy is allowed for life threatening conditions or for severe psychological distress, linked or not to prenatal diagnosis of foetal abnormalities. Socio-demographic factors related to this condition have been analysed. METHODS: Clinical records of 330 patients admitted during the years 1988-1997 to the Obstetrics and Gynaecology Department, University of Bari, Italy, for voluntary second trimester abortion, were examined. Maternal psychiatric indications have been given in nearly all of the cases. In 123 cases the indications were secondary to the women suffering a psychiatric disorder due to foetal pathologies. In 205 cases--where poor social conditions were more frequent--the indication was given on the ground of a psychiatric disorder linked to the pregnancy itself. RESULTS: Significantly higher incidence of teenagers (23.3%) and singles (50%) in women who underwent a late abortion. Students were 16.4% in this group. In primary psychiatric indication singles prevail (74.4%) and students represent 23.6% while in secondary psychiatric indication the married were 84.7%, students only 4.8%. In primary psychiatric indication 32.5% of women aged nineteen or less, while in secondary psychiatric indication this percentage was 8%. CONCLUSIONS: Among patients who have a late abortion, teenagers students and singles are prevalent, these patients have significantly more primary psychiatric indications, not linked to foetal abnormalities. The high percentage of teenagers with primary psychiatric indication could depend on inadequate information and social service. Reduction of mid-trimester terminations of pregnancy can be significantly achieved intervening in this group of young women. On the other hand, in secondary indications earlier diagnosis of foetal abnormalities must be encouraged (villocentesis instead of amniocentesis) and abortion discouraged when the foetal pathology is minor, treatable or unlikely to significantly impair the future quality of life.

BACKGROUND: The aim of this work is to demonstrate the high effectiveness of preoperative diagnosis by echotomographic study of thyroid nodules through color-Doppler sonography integrated by B-mode. The authors performed both B-mode ultrasonography and color-Doppler sonography on 125 patients expecting total thyroidectomy surgical intervention, without a previous evaluation of a number of other already performed clinical and instrumental tests. After the intervention, we compared the histologic test with the data drawn from the ultrasound scan, in order to demonstrate that color-Doppler sonography is able to provide for additional diagnostic information in the preoperative period. METHODS: One hundred and twenty five patients with thyroid pathologies were examined by both B-mode and color-Doppler sonography. Two diagnoses were made for each clinical case: the first supported by B-mode data, the second based on vascularity. Our aim was to check color-Doppler's ability to provide new information in the ultrasound diagnosis. All patients underwent a total thyroidectomy surgical intervention. The data were examined by K concordance test. RESULTS: Ultrasound data were compared with the histologic test, which showed 118 (97.4%) benign and 7 (5.6%) malignant lesions. B-mode ultrasound test gave a correct diagnosis in 115 (97%) out of 118 benign lesions and in 4 (57%) out of 7 malignant lesions, while 3 (2.5%) out of 118 cases were false positive and 3 (42.8%) out of 7 were false negative. In those cases showing a wrong conventional ultrasound diagnosis, after the integration of B-mode with color-Doppler results, a decrease was recorded in both false negative and false positive. CONCLUSIONS: Even if no correspondence was found between the different aspects of blood flow and the histologic types of lesions, this experience proves that the color-Doppler test has a high predictive value of benignity in cases with pattern I II and IV, while lesions with pattern III should be more carefully examined, since both malignant and benign lesions belong to this group. From the data drawn from this study, we are able to infer that color-Doppler sonography is undoubtedly an advantage not only in terms of cutting the false negatives, but also in the aim of obtaining a higher effectiveness in the screening of goitrogenic pathology.

Malignant mixed müllerian tumors (MMMT) of the ovary are rare, aggressive and rapidly progressive tumors. According to the available literature, the presence of metastatic disease rarely permits long term survival. We report on a 64-year old patient with stage IV ovarian MMMT who achieved a surgically-documented complete response (CR) after 6 cycles of carboplatin, mesna, ifosfamide, cis-platin. Pelvic recurrence was diagnosed 14 months later; the patient received 6 cycles of the same regimen used as first-line chemotherapy which resulted in a second complete response lasting for 4 months. The patient died 37 months after initial diagnosis due to intestinal occlusion.

A prospective randomized study was conducted at the Department of Obstetrics and Gynecology, University of Bari to compare two antimicrobial regimens, amoxicillin-clavulanic acid with cefazolin as ultra-short term prophylaxis in laparotomic gynecologic surgery. Patients were randomly allocated to receive a single dose of amoxicillin-clavulanic acid (2.2 g) [Group A] or cefazolin (2 g) [Group B] 30 minutes before surgery. Each patient was assessed daily until discharge for fever and the presence of infection of the surgical wound, urinary tract and respiratory tract. In the amoxicillin-clavulanic acid (Group A) and cefazolin (Group B) groups, overall 258 and 253 patients, respectively were evaluable for prophylactic efficacy at hospital discharge. Infectious complications were infrequent in both arms. Febrile morbidity occurred in 16 (6.3%) and 21 (8.1%) patients respectively in the amoxicillin-clavulanic acid and cefazolin groups. Wound infection and urinary tract infection were also higher but not significantly in the cefazolin group (0.8% versus 0% and 2.7% versus 2.0% respectively). There was no respiratory tract infection or septic death in either group. It is concluded that ultra-short term prophylaxis with both amoxicillin-clavulanic acid and cefazolin is safe and effective in elective laparotomic gynecologic surgery.
