Treatment timing and multidisciplinary approach in Apert syndrome

Apert syndrome is a rare congenital disorder characterized by craniosynostosis, midface hypoplasia and symmetric syndactyly of hands and feet. Abnormalities associated with Apert syndrome include premature fusion of coronal sutures system (coronal sutures and less frequently lambdoid suture) resulting in brachiturricephalic dismorphism and impaired skull base growth. After this brief explanation it is clear that these anatomical abnormalities may have a negative impact on the ability to perform essential functions. Due to the complexity of the syndrome a multidisciplinary (respiratory, cerebral, maxillo-mandibular, dental, ophthalmic and orthopaedic) approach is necessary in treating the psychological, aesthetic and functional issues. The aim of this paper is to analyse the different functional issues and surgical methods trying to enhance results through a treatment plan which includes different specialities involved in Apert syndrome treatment. Reduced intellectual capacity is associated to the high number of general anaesthesia the small patients are subject to. Therefore the diagnostic and therapeutic treatment plan in these patients has established integrated and tailored surgical procedures based on the patients’ age in order to reduce the number of general anaesthesia, thus simplifying therapy for both Apert patients and their family members

Surgical management of the acromegalic face: Could the aesthetic improvement of the face influence the patient's QoL? Combined surgical approach

Acromegaly is a chronic and progressive disease related to a disorder of growth hormone production. It may present with a variety of clinical signs and a dento-facial deformity and this results in a loss of self-esteem and a reduction of Quality of Life. Presentation of case: A 38-years–old male patient, affected by acromegaly with class III malocclusion, noticeable nose deformity and macroglossia was treated. Bi-maxillary orthognathic surgery and partial glossectomy have been performed in one-step surgey. Open rhinoplasty was done in a second step. Both dento-skeletal class III and restoration of the facial appearance have been solved. Dento-skeletal class III was completly solved together with the restoration of the facial appearance and the patient satisfaction has been achieved. Conclusions: This case report describes the successful and stable treatment of an adult patient affected by acromegaly

Three-dimensional comparison of the maxillary surfaces through ICP-Type algorithm: accuracy evaluation of CAD/CAM technologies in orthognathic surgery

Purpose: This retrospective study aims to compare the accuracy of two different CAD/CAM systems in orthognathic surgery. The novelty of this work lies in the method of evaluating the accuracy, i.e., using an Iterative Closest Point (ICP) algorithm, which matches a pair of 2D or 3D point clouds with unknown dependencies of the transition from scan s(k) to scan s(k+1). Methods: The study population was composed of ten patients who presented to the Maxillofacial Surgery Department of the University “Sapienza” of Rome for the evaluation and management of skeletal malocclusions. The patients were divided into two groups, depending on the technique used: group 1: splintless group (custom-made cutting guide and plates); group 2: splint group (using a 3D-printed splint). STL files were imported into Geomagic® Control X™ software, which allows for comparison and analysis using an ICP algorithm. The RMSE parameter (3D error) was used to calculate the accuracy. In addition, data were compared in two different patient subgroups. The first subgroup only underwent a monobloc Le Fort I osteotomy (p-value = 0.02), and the second subgroup underwent a Le Fort I osteotomy associated with a segmental osteotomy of the maxilla (p-value = 0.23). Results: Group 1 showed a 3D error of 1.22 mm ± SD 0.456, while group 2 showed a 3D error of 1.63 mm ± SD 0.303. These results have allowed us to compare the accuracy of the two CAD/CAM systems (p-value = 0.09). Conclusions: The ICP algorithm provided a reproducible method of comparison. The splintless method would seem more accurate (p-value = 0.02) in transferring the surgical programming into the operating room when only a Le Fort I osteotomy is to be performed

Sviluppo di composti di ossidazione in olio extra vergine di oliva durante la frittura: influenza della cultivar e del processo di estrazione

An experimental investigation was carried out in order to assess the influence of the cultivar and of the oil extraction process on the evolution of the oxidation compounds in extra virgin olive oil during frying. In order to do this oils from two Sardinian cultivars, obtained by two different oil extraction processes have been used to fry potato chips. The oils extracted from the potato chips were analyzed to evaluate the oxidative degradation and the antioxidant capacity. The results obtained showed that the differences observed for the oxidation triacylglycerol and polar compounds content in the extracted oils reflect the differences observed in the starting oils, while, as regards the triacylglycerol oligopolymers, the oils showed a different behavior during frying, indicating a slower polymerization rate in the oils characterized by a better quality. Un’indagine sperimentale è stata condotta allo scopo di valutare l’influenza della cultivar e del processo di estrazione dell’olio sullo sviluppo di composti di ossidazione in olio extra vergine di oliva sottoposto a frittura. Allo scopo oli monovarietali, provenienti da due cultivar sarde, ottenuti applicando due differenti tecnologie di estrazione sono stati impiegati per la frittura di patatine. L’olio estratto da queste è stato sottoposto ad indagini analitiche utili per la valutazione dei fenomeni di ossidazione e della capacità antiossidante. I risultati ottenuti hanno evidenziato che le differenze riscontrate per il contenuto in triacilgliceroli ossidati e in composti polari negli oli estratti dalle patate rispecchiavano quelle degli oli di partenza, mentre per il contenuto in oligopolimeri dei triacilgliceroli è stato evidenziato un comportamento differente degli oli nel corso della frittura, ad indicazione di una minore polimerizzazione negli oli caratterizzati da migliore qualità iniziale

Relevance of rosette patterns in variants of papillary thyroid carcinoma

IntroductionThe detection of rosette‐like clusters (RLC) of follicular cells in thyroid carcinoma has been reported mostly in the columnar cell variant of papillary thyroid carcinoma (PTC). Despite the fact that diagnosing variants of PTC is no longer encouraged by The Bethesda System for Reporting Thyroid Cytopathology, the identification of cytomorphological features such as RLC linked with these tumours might help reduce possible misinterpretation in thyroid fine needle aspiration (FNA) cytology. We accordingly investigated the potential correlation of architectural patterns including RLC with PTC variants.MethodsWe analysed 225 thyroid FNA cytology cases diagnosed as suspicious for malignancy (SFM) and positive for malignancy (M) over a 1‐year time where all samples had corresponding histology. We also included 150 benign lesions from the same period. The presence of RLC vs similar appearing solid clusters, papillary structures and microfollicles were evaluated. We also performed immunocytochemistry and molecular testing for BRAFV600E.ResultsWe included 100 (44.4%) SFM favouring PTC and 125 (55.6%) M cases with cyto‐histological correlation. On histology, all SFM and M cases showed malignancy including 140 (62.2%) classic PTC and 85 (37.8%) PTC variants. The cytomorphological patterns in all FNA samples included solid (74%), papillary (89%), microfollicular (70%), and pseudo‐RLC morphology (25.7%). We identified only pseudo‐RLC in 33 FNA specimens from PTC variant cases that included tall cell variant (42.4%), hobnail variant (21.2%) and miscellaneous variants (36.3%) of PTC. No definitive RLC were detected in our series. Immunocytochemistry and BRAFV600E were not specifically linked with an RLC pattern.ConclusionsThese findings demonstrate that in our dataset the architectural pattern of RLC was not recognised within PTC variants. However, we did identify a pseudo‐RLC pattern that was observed in association with tall cell variant and hobnail variant cases of PTC.The findings discussed in the present study demonstrate that certain architectural patterns such as rosette‐like clusters (RLC) may be recognized more frequently in specific PTC variants that may be helpful in reducing their misinterpretation. In the series presented, RLCs were observed mostly in association with tall cell and hobnail variants of PTC.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/163372/2/cyt12885_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/163372/1/cyt12885.pd

Antifungal susceptibility of invasive yeast isolates in Italy: the GISIA3 study in critically ill patients

<p>Abstract</p> <p>Background</p> <p>Yeasts are a common cause of invasive fungal infections in critically ill patients. Antifungal susceptibility testing results of clinically significant fungal strains are of interest to physicians, enabling them to adopt appropriate strategies for empiric and prophylactic therapies. We investigated the antifungal susceptibility of yeasts isolated over a 2-year period from hospitalised patients with invasive yeast infections.</p> <p>Methods</p> <p>638 yeasts were isolated from the blood, central venous catheters and sterile fluids of 578 patients on general and surgical intensive care units and surgical wards. Etest strips and Sensititre panels were used to test the susceptibility of the isolates to amphotericin B, anidulafungin, caspofungin, fluconazole, itraconazole, posaconazole and voriconazole in 13 laboratories centres (LC) and two co-ordinating centres (CC). The Clinical and Laboratory Standards Institute (CLSI) reference broth microdilution method was used at the CCs for comparison.</p> <p>Results</p> <p>Etest and Sensititre (LC/CC) MIC₉₀values were, respectively: amphotericin B 0.5/0.38, 1/1 mg/L; anidulafungin 2/1.5 and 1/1 mg/L; caspofungin 1/0.75 and 0.5/0.5 mg/L; fluconazole 12/8 and 16/16 mg/L; itraconazole 1/1.5, 0.5/0.5 mg/L; posaconazole 0.5 mg/L and voriconazole 0.25 mg/L for all. The overall MIC₉₀values were influenced by the reduced susceptibility of <it>Candida parapsilosis </it>isolates to echinocandins and a reduced or lack of susceptibility of <it>Candida glabrata </it>and <it>Candida krusei </it>to azoles, in particular fluconazole and itraconazole. Comparison of the LC and CC results showed good Essential Agreement (90.3% for Etest and 92.9% for Sensititre), and even higher Categorical Agreement (93.9% for Etest and 96% for Sensititre); differences were observed according to the species, method, and antifungal drug. No cross-resistance between echinocandins and triazoles was detected.</p> <p>Conclusions</p> <p>Our data confirm the different antifungal susceptibility patterns among species, and highlight the need to perform antifungal susceptibility testing of clinically relevant yeasts. With the exception of a few species (e.g. <it>C. glabrata </it>for azoles and <it>C. parapsilosis </it>for echinocandins), the findings of our study suggest that two of the most widely used commercial methods (Etest and Sensititre) provide valid and reproducible results.</p

Design and baseline characteristics of the finerenone in reducing cardiovascular mortality and morbidity in diabetic kidney disease trial

Background: Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD) while revealing only a low risk of hyperkalemia. However, the effect of finerenone on CV and renal outcomes has not yet been investigated in long-term trials. Patients and Methods: The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate >= 25 mL/min/1.73 m(2) and albuminuria (urinary albumin-to-creatinine ratio >= 30 to <= 5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level alpha = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure. Conclusions: FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen.
