National survey of anatomical pathology centres in Italy: the questionnaire.

OBJECTIVES: To obtain a picture of the work done in Italian anatomical pathology centres in 2014, and evaluate differences between the various centres in terms of the workloads of medical and non-medical staff. METHODS: A self-administered questionnaire designed by a SIAPEC working group was e-mailed to 256 centres and subsequently collected by the Anatomical Pathology Service of Bolzano. QlikView software was used to prepare the final database and check the quality of the data, which were processed using version 18.0 of SPSS for Windows statistical software. RESULTS: The questionnaire was completed by 120 of the centres (46.9%), which were staffed by a mean number of 6.6 physicians (range 1-24), 1.6 biologists (range 0-7), 10.8 laboratory technicians (range 2-47) and 2.2 administrative personnel (range 0-9). During 2014, the centres carried out a mean of 15,000 histology examinations (range 3,215-50,680), almost 11,700 immunohistochemistry examinations (range 0-54,359), and a mean of 1,471 molecular biology examinations (range 0-31,322) relating to a mean of 704 patients (range 0-9,434), and a mean of 16,509 cytology examinations (range 0-150,000) relating to 13,383 patients (range 0-120,000). Each centre physician issued a mean of 2,444 histology examinations reports (range 613-11,000); the ratio between the number of immunohistochemistry examinations and the number of histology examinations was 0.8 (range 0-2.7); and each laboratory technician had a mean overall annual workload of 3,072 histology, molecular biology and cytology examinations (range 793-9,882/year). These values varied widely among the participating centres. The mean ratio between the number of histology examinations carried out and the number of physicians was 1,982.77:1 a year in the small centres (< 10,000 histology cases/year), 2,627:1 a year in the medium-sized centres (10-24,999 histology cases/year), and 2,881.34:1 in the large centres (> 25,000 histology cases/year). There were significant differences between the small and medium-sized centres (p = 0.004) and between the small and large centres (p = 0.001), but not between the medium-sized and large centres.The ratio between the total number of histology, molecular biology and cytology examinations and the number of laboratory technicians was 1,963.34 in the small centres (< 10,000 examinations/year), 2,717.11 in the medium-sized centres (10,000-24,999 examinations/year), and 3,531.56 in the large centres (≥ 25,000 examinations/year). There were significant differences between the small and large centres (p = 0.001) and between the medium-sized and large centres (p = 0.004), but not between the small and medium-sized centres. CONCLUSIONS: The data collected by means of this survey provide an important, albeit partial, point of reference concerning the status of Italian anatomical pathology centres and their recent, everyday working situation.

Iodine Extravasation Quantification on Dual-Energy CT of the Brain Performed after Mechanical Thrombectomy for Acute Ischemic Stroke Can Predict Hemorrhagic Complications.

BACKGROUND AND PURPOSE: Intracerebral hemorrhage represents a potentially severe complication of revascularization of acute ischemic stroke. The aim of our study was to assess the capability of iodine extravasation quantification on dual-energy CT performed immediately after mechanical thrombectomy to predict hemorrhagic complications. MATERIALS AND METHODS: Because this was a retrospective study, the need for informed consent was waived. Eighty-five consecutive patients who underwent brain dual-energy CT immediately after mechanical thrombectomy for acute ischemic stroke between August 2013 and January 2017 were included. Two radiologists independently evaluated dual-energy CT images for the presence of parenchymal hyperdensity, iodine extravasation, and hemorrhage. Maximum iodine concentration was measured. Follow-up CT examinations performed until patient discharge were reviewed for intracerebral hemorrhage development. The correlation between dual-energy CT parameters and intracerebral hemorrhage development was analyzed by the Mann-Whitney U test and Fisher exact test. Receiver operating characteristic curves were generated for continuous variables. RESULTS: Thirteen of 85 patients (15.3%) developed hemorrhage. On postoperative dual-energy CT, parenchymal hyperdensities and iodine extravasation were present in 100% of the patients who developed intracerebral hemorrhage and in 56.3% of the patients who did not (P = .002 for both). Signs of bleeding were present in 35.7% of the patients who developed intracerebral hemorrhage and in none of the patients who did not (P < .001). Median maximum iodine concentration was 2.63 mg/mL in the patients who developed intracerebral hemorrhage and 1.4 mg/mL in the patients who did not (P < .001). Maximum iodine concentration showed an area under the curve of 0.89 for identifying patients developing intracerebral hemorrhage. CONCLUSIONS: The presence of parenchymal hyperdensity with a maximum iodine concentration of >1.35 mg/mL may identify patients developing intracerebral hemorrhage with 100% sensitivity and 67.6% specificity.

Cone beam computed tomography for the assessment of linear scleroderma of the face.

BACKGROUND: To date, standardized methods for assessing the disease progression of linear scleroderma of the face (LSF) are lacking. OBJECTIVES: We investigated whether Cone Beam Computed Tomography (CBCT) may represent a reliable tool for assessing linear scleroderma of the face (LSF). METHODS: Ten patients with LSF and five age-matched controls underwent CBCT assessment. The transverse sections at three anatomic levels of the maxillofacial bones were analyzed. Measurements of soft tissue and total thickness of both affected and unaffected side of the face were made by a standardized methodology. Six raters evaluated CBCTs twice and blindly one from the other. The intra- and inter-rater reliability was assessed by the Intraclass Correlation Coefficient (ICC). RESULTS: CBCT was fast and well tolerated by the patients. The inter-rater concordance for the total thickness was excellent, mean ICC 0.75 for patients, 0.89 for controls. The mean ICC for soft tissue thickness was 0.49 for patients, 0.66 for controls. 58.3% of the measurements for patients and 91.2% of those for controls showed excellent ICC results (≥ 0.75). The intra-rater concordance resulted optimal (ICC 0.77-0.99). CONCLUSIONS: CBCT is a reliable technique to assess skin and bony changes of LSF.

Second-look surgery plus HIPEC for patients with colorectal cancer at high risk of peritoneal carcinomatosis: Should we resect the initial anastomosis? An observational study.

BACKGROUND: Cytoreductive surgery (CCRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) improves the overall survival in selected cases of peritoneal carcinomatosis (PC) of colorectal origin. Second-look surgery in asymptomatic patients at high risk of developing PC has shown encouraging results. This study aims at identifying cases in which initial anastomosis should be resected. METHODS: Patients treated by second-look surgery and HIPEC were identified from a prospective database. High-risk was defined as synchronous resected and minimal PC, ovarian metastasis or perforated primary tumor. Patients were divided in two groups based on intra-operative evaluation of the anastomosis: possibly-invaded (PI) and unlikely-invaded (UI). PI was defined as 1) PC away from the anastomosis, 2) nodules resting on the anastomosis 3) anastomotic stenosis or anastomotic thickening. Anastomosis in the PI group were resected. RESULTS: Forty patients were included: 12 in the PI group and 28 in the UI group. Incidence of pathological anastomotic invasion was 42% (5 on 12 patients) in the PI group. In the UI group, 2 patients had anastomotic recurrence, both associated with peritoneal recurrence. Morbidity and mortality was not influenced by anastomosis resection. The presence of suspicious nodules on the anastomosis had a sensitivity of 100% and a specificity of 89% in predicting anastomotic invasion. CONCLUSION: In second-look surgery and HIPEC for colorectal cancer at high-risk of PC, anastomosis should be resected when overlying PC nodules are found. This attitude is supported by high sensitivity of this finding for anastomotic invasion and low morbidity related to anastomotic resection.

Patients' quality of life after allogeneic haematopoietic stem cell transplantation: mixed-methods study.

Allogeneic haematopoietic stem cell transplantation (HSCT) is an increasingly widespread therapy method. It is associated with many socio-psychological and physical risks. Forty-four subjects, who were clinically monitored at the Bolzano BMT Centre including a follow-up period of at least 3 months, completed the questionnaire Functional Assessment of Chronic Illness Therapy-Bone Marrow Transplantation (version 4). Semi-structured, problem-oriented interviews were conducted with seven randomly selected subjects, the results of which were subjected to a summarising content analysis according to Mayring. The results from the quantitative and qualitative parts were compared based on triangulation. In the random sample, 22.7% stated that they were highly satisfied with their current quality of life (QOL). Throughout all dimensions of the questionnaire, women showed lower scores than men. The results revealed a positive correlation between the post-HSCT period and QOL (r(s)=0.338, P=0.025), especially regarding the social/family (r(s)=0.411, P=0.006) and emotional well-being (r(s)=0.306, P=0.043). The interviews primarily revealed dependence and inability to work. The support received from family, friends and hospital staff and the shift in priorities because of the transplantation were perceived as positive. The comparison mainly leads to corresponding results of the quantitative and qualitative parts of the study. Patient self-rating using questionnaires and interviews plays a direct and relevant role in the assessment of the QOL after allogeneic HSCT.

Complementary and Alternative Medicine (CAM) in paediatric rheumatology: a European perspective.

OBJECTIVES: To analyse the use of complementary and alternative medicine (CAM) in children with rheumatic diseases, treated at a paediatric rheumatology centre in Italy. METHODS: Parents of children with different kinds of chronic rheumatic diseases anonymously completed a questionnaire about their children's past or current use of CAM. Two groups of patients were analysed: Group A consisted of children who were still attending the centre; Group B consisted of children who had not attended the clinic for more than one year. RESULTS: 150 completed surveys were analysed: 22 paediatric patients (14.7%), 10/100 in group A and 12/50 in group B, used CAM to treat their diseases. The therapies used the most were homeopathy, herbal remedies, vitamins and minerals. We observed a significantly greater use of CAM among patients who had not attended the clinic for more than one year (24%) as compared to those who were regularly checked (10%) (p=0.02). Parents' use of CAM was significantly related to its use for their children (p=0.001). A poor outcome, probably related to the exclusive use of alternative treatments, was observed in three out of six patients who had completely stopped using traditional immunosuppressive drugs. CONCLUSIONS: Physicians should be aware of the use of CAM particularly in patients who skip their regular check-ups. The use of CAM to treat childhood rheumatic conditions in Italy seems to be less frequent than in North America.

Factors affecting survival in juvenile systemic sclerosis.

OBJECTIVES: To determine whether demographic, clinical and immunological features may predict the outcome in juvenile SSc (JSSc). METHODS: Clinical and laboratory characteristics of patients with JSSc collected from paediatric rheumatology centres worldwide were analysed. First, univariate tests identified those features significantly related with fatal outcome, and then multivariate logistic regression analysis was applied to determine the predictors of mortality. RESULTS: One hundred and thirty-four patients from 40 centres were eligible for the analysis. Sixteen patients died and a rapidly fatal course was observed in most of them: 4/16 died within 1 yr after diagnosis and 10/16 within 5 yrs. At the moment of diagnosis, patients with poor outcome showed a significantly higher frequency of internal organ involvement, particularly cardiac, respiratory and gastrointestinal systems. No significant difference emerged for entity of skin, vascular and musculo-skeletal involvement, nor for auto-antibodies profile and laboratory tests. Multivariate analysis showed the following factors to be significant predictors of mortality: fibrosis on chest X-rays [odds ratio (OR) 11.2], raised creatinine levels (OR 22.7) and pericarditis (OR 41.3), while a short disease duration at diagnosis conferred protection (OR 0.3). CONCLUSIONS: All patients with JSSc and fatal outcome were affected by the diffuse form of the disease, and most of them showed a very rapid progression and early signs of internal organ involvement. This suggests that, in children, SSc may have two possible courses: a rapid development of internal organ failure leading to severe disability and eventually to death, or a slow course of the disease with lower mortality.

Distinctive clinical features of pediatric systemic lupus erythematosus in three different age classes.

It is estimated that around 20% of patients with systemic lupus erythematosus (SLE) have their onset in childhood but there have been conflicting data about the prevalence and severity of the clinical features in different age classes. We conducted this study to analyse the clinical features of patients with pediatric SLE (pSLE) with onset in infancy, prepubertal and postpubertal age. The charts of patients followed at the Department of Pediatrics, University of Padua, who met the criteria for SLE diagnosis, were reviewed. Patients were divided into three groups based on age at disease onset: group A, patients < or =2 years old, group B patients aged between 2 and 10 years, group C patients between 11 and 16 years of age. The clinical and laboratory characteristics of each group were compared. Forty-two patients with pSLE entered the study: 2 were diagnosed before the age of 2 years, 11 between 2 and 10 years and 29 between 10 and 16 years. Eleven more patients with infantile (onset <2 years) SLE (iSLE) were found by a systematic literature search on PubMed and EmBASE and added for analysis to the group A. The female preponderance was significant only in postpubertal patients (F:M = 6.3: 1) whereas the other two groups presented a similar F:M ratio (1.2: 1). In comparison with the other two groups, iSLE showed a significantly higher prevalence of cardiovascular and pulmonary involvement, anemia and thrombocytopenia and a shorter disease duration at time of diagnosis. The postpubertal group showed a higher frequency of musculoskeletal involvement and leukopenia. In prepubertal patients there was no female preponderance and the frequency of clinical features was intermediate between infantile and postpubertal patients. Complement fractions level, antinuclear antibodies (ANA), anti-dsDNA, anti-cardiolipin antibodies and lupus anti-coagulant autoantibodies were not significantly different in the three groups. In general, the prevalence of internal organs involvement in pSLE seems to decrease with age. In infants, SLE is more severe than in the following ages. Postpubertal patients have a strong female preponderance and more specific signs of disease at onset. Prepubertal patients have an intermediate disease severity and no gender predilection.

A new computerized method for the assessment of skin lesions in localized scleroderma.

OBJECTIVE: Up to now, no validated tools are in use for the assessment of the skin lesions in localized scleroderma (LS). The aim of this study is to evaluate the performance of a new computerized skin score (CSS) method for the measurement of circumscribed lesions in LS. METHODS: The study consisted of three phases: set up of the CSS technique, measurement of target lesions of LS patients, assessment of intra- and inter-rater reliability. The CSS technique consists in delimitating the indurate lesion on an adhesive transparent film, transferring it over a cardboard and then calculating the affected area with a specifically created software. The technique was explained to a panel of 10 physicians with different expertise in LS (three paediatric rheumatologists, two dermatologists, five paediatric residents). All participants, singularly and blindly to the others, examined 10 consecutive patients twice after a time interval of at least 6 h. The intra-observer variability was evaluated by the repeatability coefficient and the inter-rater reliability by the intra-class correlation coefficient (ICC). RESULTS: The repeatability coefficients were good, ranging between 1.90 and 7.03. The mean values of skin scores were not significantly different among the examiners. The ICC for indurate area calculation were high in both the experts (0.97) and the residents (0.91-0.94). CONCLUSIONS: CSS has shown to be a reliable method to assess the skin lesions in patients with LS. It is reproducible, easy to use and, with the support of the CSS software, applicable worldwide.

Immunocytochemistry of p16INK4a in liquid-based cervicovaginal specimens with modified Papanicolaou counterstaining.

AIM: To evaluate the feasibility and value of a modified Papanicolaou counterstain for p16(INK4a) immunostaining in liquid-based cervicovaginal samples. METHODS: Immunocytochemical analyses were carried out with p16(INK4a) and modified Papanicolaou counterstain on 81 liquid-based samples, including 23 of within normal limits (WNL), 6 of low-grade squamous intraepithelial lesion (LSIL), 20 of high-grade squamous intraepithelial lesion (HSIL), 16 of atypical squamous cells of undetermined significance (ASC-US) and 16 of atypical squamous cells, high-grade lesion cannot be excluded (ASC-H). Results were compared with histological or cytological follow-up. For comparison, samples from 29 more cases (10 of LSIL, 10 of ASC-H and 9 of HSIL) were immunostained with p16(INK4a) and conventionally counterstained with haematoxylin. The intensity of immunostaining in cases of squamous intraepithelial lesion (SIL) was assessed using a 0-3 scoring system. Interobserver agreement was calculated by kappa statistics. RESULTS: Expression of p16(INK4a) was detected in 3 of 23 cases of WNL, 4 of 6 cases of LSIL, all cases of HSIL, 5 of 16 cases of ASC-US and 13 of 16 cases of ASC-H. Excluding two cases with no residual dysplastic cells in the immunocytochemistry, all cases of cervical intraepithelial neoplasia (CIN)2 or CIN3 at follow-up expressed p16(INK4a) and none of the p16(INK4a)-negative cases showed a high-grade lesion at follow-up. No evident differences in pattern or intensity of p16(INK4a) expression were observed between the specimens of the study and control groups. Interobserver agreement was significantly better in the study group than in the group with conventional immunostaining (combined kappa 0.773 v 0.549; p<0.05), and still better, albeit statistically not significant, than with conventional immunostaining and cervical smear test together (combined kappa 0.773 v 0.642). CONCLUSION: Immunocytochemistry with p16(INK4a) and modified Papanicolaou counterstain may add to the cervicovaginal cytology the full potentiality of p16(INK4a) without the need of a further slide and the risk of loss of dysplastic cells, yet maintaining the typical morphological features of the smear test.

Laparostomy in the treatment of severe peritonitis: a review of 60 cases.

The aim of this study was to evaluate the use of laparostomy in the management of patients with severe abdominal infections. From June 1992 to December 2000 sixty patients with severe peritonitis were treated with laparostomy and studied retrospectively. Thirty-eight had post-operative peritonitis. Twelve patients had necrotic pancreatitis. Five patients had peritonitis due to ischemic colitis. Two patients had hemoperitoneum following multiple abdominal operations, and three patientshad severe wound dehiscence. The APACHE II score was used to determine the severity of patients' condition. The median age was 46 years, the mean APACHE II score was 19.7, and the observed mortality was 38.3%. The incidence of spontaneous fistulation of the exposed loop of intestine was 13.3%. In 11 patients abdominal wall closure was accomplished by primary intention. Incisional hernias were inevitable in the rest of patient and were repaired 1 years after surgery. Laparostomy is a good way to manage patients with severe peritonitis but it should be performed before irreversible septic shock and subsequent multi organ failure develop.
