Abstract
PURPOSE Although honeycombing is one of the key features for the diagnosis of idiopathic pulmonary fibrosis (IPF), its origin and evolution are still poorly understood. The aim of our study was to analyse the natural history of honeycombing in patients treated with single-lung transplantation. MATERIALS AND METHODS We considered seven patients who underwent single-lung transplantation; two of them (28.6%) were excluded from our analysis because they died in the posttransplantation period, whereas the remaining five (71.4%) were evaluated with computed tomography (CT) over 67.6±38.56 months. Each CT scan was assessed for disease extension and cyst size (visual score and size of target cysts); CT scans acquired after 2006 were also assessed for native lung volume. RESULTS All patients showed disease progression (with a concurrent reduction in lung volume in two, 40%) and a progression of honeycombing, with increased number and size of cysts in four (80%). We observed dimensional changes in all target cysts (enlargement or reduction); three patients (60%) also had radiological evidence of complications, such as spontaneous rupture with pneumothorax and development of mycetomas within the cysts. CONCLUSIONS Honeycombing is a dynamic process in which the overall trend is represented by a dimensional increase in cystic pattern; however, single cysts may have a different evolution (enlargement, reduction or complications). This behaviour could be explained by the variety of the pathogenetic processes underlying honeycombing, with cysts that may present abnormal communication with the airway, including the development of a check-valve mechanism.

Abstract
SLE begins with renal symptoms in about 30-50% of the patients and after 10 years over 70% of them has complications. In the last years the medical therapy improved the outcome of SLE and its complications. Presently, the survival for lupus nephritis is 80% after five years. The nephritis treatment is divided into remission-inducing treatment that is followed by remission-maintaining treatment. Moreover, it is considered the therapy for preventing or reducing toxic and side-effects from drugs and the therapy for flare-ups. To initiate the specific therapy is important to consider the histological class (WHO). In the remission-inducing treatment steroids are used alone for 3-6 months in class IIB or in association with cyclophosphamide in classes III-IV and V and for flare-ups. For remission-maintaining treatment steroids are used in association with azathioprine. The drugs improved the outcome of nephritis but produced side-effects that determined the suspension of the drug and/or reduction of dosage and/or the use of other drugs like mycophenolate mofetil or rituximab.

Abstract
The aim of this study was to assess the prevalence of genetic changes in either the HIV reverse transcriptase (RT) or protease (Pro) genes in a cohort of patients naïve for anti-retroviral therapy. Of 61 patients, 43 (70.5%) were infected with HIV strains harbouring at least one resistance-related mutation, with 41 (67.2%) harbouring newly recognised treatment-related mutations. Among the 61 patients, the prevalence of specific mutations in the RT gene was as follows: 39A, 1.6%; 43E, 1.6%; and 228H, 1.6%. The prevalence of specific mutations in the Pro gene was as follows: 11I, 1.6%; 13V, 26.2%; 35D, 19.6%; 45R, 1.6%; 58E, 1.6%; 62V, 31%; 72V, 11.4%; 72M, 6.5%; 72T, 3.2%; 75I, 1.6%; and 89M, 13%. A higher prevalence of newly recognised mutations was found in strains from patients infected through sexual practices (30/36 = 83.4% vs. 11/25 = 44%; p 0.0023; OR 10.91; 95% CI 3.14-40.39). These findings support the use of resistance testing in patients naïve for anti-retroviral therapy, and suggest that the possible impact of newly recognised treatment-related mutations on clinical outcome requires further investigation.

Abstract
Hemodialysis patients on maintenance erythropoietin need an adequate supply of iron to optimize therapy and achieve and maintain target levels of hemoglobin. Evaluation of iron stores and early detection of iron deficiency are essential for management of erythropoiesis in chronic renal failure, but there is still no single biochemical or hematological parameter that is sensitive or specific enough to completely describe the distribution of iron in the body. Serum transferrin receptor (sTfR) is a marker of iron that is available for erythropoiesis. We selected 2 clinical cases in which hemodialysis patients were receiving maintenance erythropoietin. To suggest how sTfR can be used in its double diagnostic meaning according to the clinical context of the patient, sTfR was evaluated in one case as a marker of iron deficiency and in the other as a marker of erythropoiesis. The association of sTfR with hematological parameters of iron-deficient erythropoiesis (reticulocyte hemoglobin content, percentage of hypochromic erythrocytes, ratio of reticulocyte hemoglobin content to hemoglobin content) and parameters of stimulated erythropoiesis (absolute reticulocyte count, immature reticulocyte fraction) increases the accuracy of sTfR in its double diagnostic power.

Abstract
A retrospective review was made of the bacteriological and medical records of patients with culture-confirmed pulmonary tuberculosis who attended the IRCCS San Matteo Polyclinic of Pavia, between 1990 and 2000. Altogether, 279 patients were included in the survey: 220 new cases and 59 prior treatment cases. Resistance to at least one drug, and resistance to both isoniazid and rifampicin (MDR) were more common among previously treated patients than among new cases (86.4% vs. 34.1%, and 44% vs. 5.9%, respectively). While the frequency of resistance to any drug showed no variation in the period examined, a trend toward a progressive decrease in the frequency of primary MDR-TB was observed (from 11.9% in 1990-1992 to 1.3% in 1998-2000). The level of resistance observed in our study suggests that all isolates of Mycobacterium tuberculosis should be tested for drug susceptibility, especially when obtained from patients who report a previous episode of the disease.

Abstract
In this study we evaluated the antibacterial activity of mastic gum, a resin obtained from the Pistacia lentiscus tree, against clinical isolates of Helicobacter pylori. The minimal bactericidal concentrations (MBCs) were obtained by a microdilution assay. Mastic gum killed 50% of the strains tested at a concentration of 125 microg/ml and 90% at a concentration of 500 microg/ml. The influence of sub-MBCs of mastic gum on the morphologies of H. pylori was evaluated by transmission electron microscopy. The lentiscus resin induced blebbing, morphological abnormalities and cellular fragmentation in H. pylori cells.

Abstract
Although the short- and medium-term (5-10 years) outcome of patients with lupus nephritis has been studied extensively, there are very few data on the second and subsequent decades. We studied outcome in 110 local patients investigated at a single centre before 1986, who all had potential follow-up of more than 10 years (actual 2-31 years, median 15.5 years). At last follow-up, 40 patients were dead and 70 alive, nine of whom were on maintenance dialysis or transplanted, actuarial survivals being 84%, 72%, 62%, 61% and 54% at 5, 10, 15, 20 and 25 years for the group as a whole. Survival was better in the cohort 1976-86 (n = 60) than in that from 1963-75 (n = 50) (90, 81 and 76% vs. 78, 56 and 43% at 5, 10 and 15 years, p < 0.001). Sepsis (12) and myocardial infarction (8) were the principal causes of death. Of living patients with renal function, 38% had normal urine and renal function, 11 were off all treatment (19%), 62% had persistent proteinuria and 18% had reduced but generally stable renal function. Renal failure, in those patients who developed it, occurred during the first decade and none of 67 patients actually followed more than 10 years subsequently went into renal failure. Induction treatment was with prednisolone, combined with azathioprine in more severe forms of nephritis, and from the middle 1970s to 1986, 30 with methylprednisolone and in 12 cases plasma exchange. Seventeen other patients were treated using oral cyclophosphamide during the 1960s. No patient received i.v. cyclophosphamide as induction therapy, although nine patients had this form of treatment later, largely because of non-compliance. Serious complications of lupus and/or its treatment occurred in 49%: sepsis in 32, ischaemic heart disease in 20, thrombosis in one and avascular necrosis of bone in eight. In contrast, fracturing osteoporosis occurred in only three, and cataracts requiring surgery and diabetes mellitus in none. The very long-term outlook of lupus nephritis, especially its more severe forms, has improved, but that with current management strategies only a minority of patients are able to stop treatment altogether, and the incidence of serious complications is high.

Abstract
A single Polymerase Chain Reaction (PCR) within the rpoV gene was developed to rapidly distinguish mycobacteria isolated from clinical specimens. The species identifications of Mycobacterium avium complex (MAC) and Mycobacterium tuberculosis were congruent with standard typing techniques. The analysis was targeted toward the identification of species-specific markers for the clinically relevant M. tuberculosis and M. avium. In addition, HaeIII digestion of the amplification products yielded isolates-specific bands.

Abstract
The recently developed ESP Culture System II (AccuMed, Chicago, Ill.) was compared with radiometric BACTEC 460TB (Becton Dickinson, Towson, Md.) and with Lowenstein-Jensen medium for recovery of mycobacteria from over 2,500 clinical specimens both of respiratory and nonrespiratory origin, including blood. The majority of the 219 mycobacterial isolates (129) belonged to the Mycobacterium tuberculosis complex, followed by 37 isolates of the Mycobacterium avium complex (MAC) and 53 isolates of eight other mycobacterial species. Rates of recovery obtained with BACTEC, ESP, and Lowenstein-Jensen medium were 89, 79, and 64%, respectively, with such differences being statistically significant. Different media and systems appeared to behave differently when the more frequently detected organisms were considered: M. tuberculosis complex isolates grew better with BACTEC, and MAC isolates grew better with ESP. An analysis of the combinations of Lowenstein-Jensen medium with BACTEC and with ESP did not reveal significant differences in recovery rates. With regard to the times needed for the detection of positive cultures, they were significantly longer on Lowenstein-Jensen medium (average, 28 days) than with the remaining two systems, between which there was no difference (average, 18 days). We conclude, therefore, that the ESP system, when used in combination with a solid medium, performs as well as the thoroughly validated radiometric BACTEC system and offers the advantages of full automation and absence of radioisotopes.

Abstract
Mycobacteria Growth Indicator Tube (MGIT) is a recently introduced rapid growth detection method which uses an oxygen quenched fluorescent indicator. The present study evaluated the ability of this new method to determine the drug susceptibility of Mycobacterium avium complex (MAC). Thirty strains recovered from patients with AIDS were tested for susceptibility to clarithromycin, rifabutin, ciprofloxacin, azithromycin and amikacin using MGIT. Results were compared to susceptibilities determined by the agar dilution method. The results obtained showed a 100% correlation between MGIT and the agar dilution method for rifabutin and clarithromycin. There was a 100% correlation between the two methods for azithromycin against 27 strains. MGIT was well correlated with the agar dilution method for detecting resistance to clarithromycin, rifabutin and azithromycin in 4 days, but the correlation was poor when susceptibilities to ciprofloxacin and amikacin were determined. This rapid method is non-radiometric, noninvasive and does not require any special instruments.

Abstract
Mycobacterium celatum is a recently described species which, on the basis of conventional tests, may be misidentified as Mycobacterium xenopi or as belonging to the Mycobacterium avium complex. Only genomic sequencing or high-performance liquid chromatography of cell wall mycolic acids can presently allow a correct identification of this mycobacterium. Two cases of infection due to M. celatum, in AIDS patients, are described here. The quantitative susceptibility pattern of the isolates to a wide spectrum of drugs is also reported.

Abstract
A 24-year-old HIV negative unemployed intravenous heroin addict with teeth in poor condition was admitted to hospital with left hemiparesis; CT scan of the brain revealed a hypodense area in the right parietal region. He was apyrexial with marked leukocytosis and raised ESR, had an aortic diastolic murmur and an echocardiogram showed marked aortic insufficiency with possible small vegetations on the anterior leaflet of the mitral valve. Lactobacillus Casei was isolated from repeated blood cultures. Therapy with penicillin G together with netilmicin for 6 weeks led to improvement of his clinical status and an echocardiogram on discharge showed clear improvement. Regression of the cerebral lesions was also demonstrated on CT scan. We conclude that lactobacillus species should be sought in all haemoculture negative endocarditis in the presence of tooth disease.

Abstract
Six volunteers received intravenously a single 1 g dose of cefoxitin or cefotetan. The 2 groups were crossed after a week of washout. Five strains each of Escherichia coli, Klebsiella pneumoniae, Bacteroides fragilis and Bacteroides thetaiotaomicron susceptible to the administered drugs were tested for serum bactericidal activity (SBA). Blood samples were obtained before and 0.5, 3.0 and 12.0 hours after antibiotic injection. SBA was determined using microtitre procedures. Anaerobic bacteria were incubated in an anaerobic chamber. Cefotetan showed a very high SBA both against aerobes and anaerobes over the 12 hour sampling time. Cefoxitin reached satisfactory SBA values only 0.5 hours after administration.

Abstract
Cefotaxime is a new broad-spectrum injectable cephalosporin which is stable to most beta-lactamases. In this study we have evaluated the antibacterial activity of cefotaxime comparatively with the activity of cephalotin against 66 Gram-negative bacteria and 31 Gram-positive bacteria by using an automated antimicrobial susceptibility determination system. Cefotaxime was markedly more active than cephalotin against Klebsiella pneumoniae, Proteus, Enterobacter, Escherichia coli and Serratia. Against Gram-positive clinical isolates cefotaxime was less active than cephalotin. Regrowth was observed mainly with cephalotin against Gram-negative clinical isolates, therefore the results obtained after a few hours with automated system should be carefully interpreted.
