RESUMO
INTRODUCTION: Fine-needle aspiration cytology (FNAC) is a basic step in the diagnosis of salivary gland tumors that have a wide variety of histological types. The recent Milan system for reporting salivary gland cytopathology (MSRSGC) can correlate the risk of malignancy with precise cytological features. A revised version was recently proposed to improve the surgical relevance and facilitate uniform management. MATERIAL AND METHODS: A multicenter study retrospectively used the original and revised MSRSGC criteria to classify a series of patients who received surgery after FNAC. RESULTS: We enrolled 503 patients from three tertiary centers. The risk of malignancy for the MSRSGC resulted 19.5% in cat. I, 14.3% in cat. II, 17.6% in cat. III, 3.6% in cat. IVa, 24.6% in cat. IVb, 66.7% in cat. V, and 96.8% in cat. VI. The results from the revised MSRSGC were consistent with the original values. CONCLUSION: The MSRSGC is a promising classification system. In our opinion, the revised version of the MSRSGC supplements FNAC with some crucial clinical information and can better identify the appropriate treatment in each category.
RESUMO
AIMS: This pilot study aimed to evaluate prospectively the use of inlet radiographs of the hip as an alternative method of the assessment of reduction after the surgical treatment of developmental dysplasia of the hip (DDH). PATIENTS AND METHODS: The children in this study underwent surgery between January 2013 and January 2015. All had inlet radiographs and CT scans post-operatively. Data were analysed by determining inter-observer reliability and intra-observer reproducibility, using the kappa value (K). Differences were settled by discussion between the two observers until a consensus was reached. The sensitivity and specificity of the radiographic and CT results were compared. A total of 26 radiographs were obtained from 23 children, with a mean age of 2.38 years (one to five). RESULTS: Similar high levels of intra- and inter-observer agreement were observed (K = 0.834, 95% confidence interval (CI)). There was a high agreement between the radiographic and CT results (K = 0.834, 5% CI), with excellent sensitivity and a specificity of 95.5%. CONCLUSION: These results suggest that inlet radiographs may be a reliable method of assessing the reduction of the hip after the surgical treatment of DDH.

OBJECTIVE: Analysing most relevant clinical features and concordance between different functional scales in patients with advanced medical diseases (PAMD). METHODS: Cross-sectional multicentre study that included PAMD (heart, lung, kidney, liver, and neurological diseases) in hospital settings from February 2009 to October 2010. We analysed clinical, biological and functional features in performing activities of daily living (ADL) by medians of Barthel Index (BI); additionally we assessed their performance status by medians of Eastern Cooperative Oncology Group-Performance Status (ECOG-PS) and Palliative Performance Scale (PPS) scores. We evaluated the concordance of these instruments in assessing functional impairment by κ and intraclass correlation coefficient tests. RESULTS: 1847 patients were included (average age 79â years, 50.1% men). Most common symptoms were dyspnoea (62.31%), asthenia (23%) and delirium (20.14%). Functional assessment showed a high prevalence of severe or total impairment in performing basic ADL by medians of used instruments (BI median=35 (IQR=70), and 52.1% of patients with severe-total impairment; ECOG-PS median=2 (IQR 30), and 44% of patients with severe-total impairment; and PPS median=50 (IQR 30), and 32% of patients with severe-total impairment). Concordance among these instruments was acceptably good (κ indexes ranging from 0.653 to 0.745 (p<0.0001)). CONCLUSIONS: PAMD represent a population with severe functional impairment, which requires a multidisciplinary approach for proper management. Assessment of functional ability in this population by BI, ECOG-PS, and PPS showed good concordance.

Laxatives abuse has been associated with an increased risk for colon cancer. However, little is known about laxatives long-term carcinogenic potential in experimental studies. The present study was designed to investigate the effects of bisacodyl (4.3 and 43 mg/kg) and cascara (140 and 420 mg/kg) on azoxymethane (AOM)-induced aberrant crypt foci (ACF) and tumors. Animals, divided in 10 groups were treated with AOM and laxatives (alone or in combination) for 13 weeks. At the end of treatment animals were killed and the colon removed and analysed for the determination of ACF and tumors. Bisacodyl (4.3 and 43 mg/kg), given alone, did not induce the development of colonic ACF and tumors. Bisacodyl (4.3 mg/kg) coupled with AOM increased the number of crypt per focus, but not the number of tumors. Bisacodyl (43 mg/kg) significantly increased the number of crypt per focus and tumors. Cascara (140 and 420 mg/kg) did not induce the development of colonic ACF and tumors and did not modify the number of AOM-induced ACF and tumors. The results of the present study indicate a possible promoting effect of bisacodyl on rat colon carcinogenesis (especially at higher doses) and absence of any promoting or initiating activity of a laxative and diarrhoeal dose of cascara.

Current evidence suggests that aberrant crypt foci (ACF) can be used to evaluate agents for their potential colon carcinogenic activity. The aim of the present study was to determine whether senna pod extract (SE) itself induces ACF and tumors in the rat colon or increases the development of ACF and tumors induced by azoxymethane (AOM). A daily administration of SE 10 mg/kg by mouth for 13-28 weeks produced a weak laxative effect but did not itself cause the appearance of ACF or tumors. The numbers of ACF and tumors induced by AOM were, however, increased by a dose of SE (100 mg/kg) able to induce chronic diarrhea over three months. These results suggest that SE does not cause the appearance of ACF or tumors in the rat colon nor does it have a promoting effect when given to rats at a dose that produces laxation (10 mg/kg), whereas a diarrhogenic dose (100 mg/kg) increases the appearance of tumors induced by AOM.
