ABSTRACT

PURPOSE: To assess the clinical utility of chest computed tomography (CT) reports for non-small-cell lung cancer (NSCLC) staging generated by inexperienced readers using structured reporting (SR) templates from the Royal College of Radiologists (RCR-SR) and the Italian Society of Medical and Interventional Radiology (SIRM-SR), compared to traditional non-systematic reports (NSR). METHODS: In a cohort of 30 NSCLC patients, six third-year radiology residents reported CT examinations in two 2-month-apart separate sessions using NSR in the first and NSR, RCR-SR, or SIRM-SR in the second. Couples of expert radiologists and thoracic oncologists in consensus evaluated completeness, accuracy, and clarity. All the quality indicators were expressed on a 100-point scale. The Wilcoxon signed ranks, and Wilcoxon-Mann Whitney tests were used for statistical analyses. RESULTS: Results showed significantly higher completeness for RCR-SR (90 %) and SIRM-SR (100 %) compared to NSR (70 %) in the second session (all p < 0.001). SIRM-SR demonstrated superior accuracy (70 % vs. 55 %, p < 0.001) over NSR, while RCR-SR and NSR accuracy did not significantly differ (60 % vs. 62.5 %, p = 0.06). In the second session, RCR-SR and SIRM-SR surpassed NSR in completeness, accuracy, and clarity (all p < 0.001, except p = 0.04 for accuracy between RCR-SR and NSR). SIRM-SR outperformed RCR-SR in completeness (100 % vs. 90 %, p < 0.001) and accuracy (70 % vs. 62.5 %, p = 0.002), with equivalent clarity (90 % for both, p = 0.27). CONCLUSIONS: Inexperienced readers using RCR-SR and SIRM-SR demonstrated high-quality reporting, indicating their potential in radiology residency programs to enhance reporting skills for NSCLC staging and effective interaction with all the physicians involved in managing NSCLC patients.

ABSTRACT

The increasing complexity of academia, with its demanding working conditions and uncertain career opportunities, may affect the mental health of academics and potentially lead to mental health problems. The aim of this study is to determine the prevalence of depressive and anxiety symptoms in the academic population of the University of Udine and to compare symptoms in senior and younger academics and administrative staff.A cross-sectional survey was conducted between June and December 2020, involving academic and administrative staff in all departments. The prevalence of depressive and anxiety symptoms was assessed using the PHQ-9 and GAD-7 tools. The relationship between mental health outcomes and job role was analyzed using nonparametric tests and ordinal logistic regression.A total of 366 individuals participated: 109 junior academics, 146 senior and 111 administrative staff. The proportion of women was 55.7% and the mean age was 47.9 years. The prevalence of depressive and anxiety symptoms in the studied population was 25.7% (95% IC 21.5-30.4) and 22.7% (95% IC 18.7-27.2) respectively, with junior academics having the higher prevalence of both symptoms. Univariate models suggest a higher risk for anxiety symptoms OR 1.89 (1.13-3.17) for women.The prevalence of depressive symptoms is higher in our academic community than in the general population, especially among junior academics. These findings may reflect the impact of uncertain career and challenging environment on the mental health of young academics. Universities should provide more support to young academics so that they can contribute effectively and healthily to the advancement of research.

ABSTRACT

BACKGROUND: Thyroid dysfunction has been observed in patients with COVID-19, and endocrinologists are requested to understand this clinical issue. Pandemic-related restrictions and reorganization of healthcare services may affect thyroid disease management. OBJECTIVE AND METHODS: To analyze and discuss the relationship between COVID-19 and thyroid diseases from several perspectives. PubMed/MEDLINE, Google Scholar, Scopus, ClinicalTrial.gov were searched for this purpose by using free text words and medical subject headings as follows: "sars cov 2", "covid 19", "subacute thyroiditis", "atypical thyroiditis", "chronic thyroiditis", "hashimoto's thyroiditis", "graves' disease", "thyroid nodule", "differentiated thyroid cancer", "medullary thyroid cancer", "methimazole", "levothyroxine", "multikinase inhibitor", "remdesivir", "tocilizumab". Data were collected, analyzed, and discussed to answer the following clinical questions: "What evidence suggests that COVID-19 may induce detrimental consequences on thyroid function?"; "Could previous or concomitant thyroid diseases deteriorate the prognosis of COVID-19 once the infection has occurred?"; "Could medical management of thyroid diseases influence the clinical course of COVID-19?"; "Does medical management of COVID-19 interfere with thyroid function?"; "Are there defined strategies to better manage endocrine diseases despite restrictive measures and in-hospital and ambulatory activities reorganizations?". RESULTS: SARS-CoV-2 may induce thyroid dysfunction that is usually reversible, including subclinical and atypical thyroiditis. Patients with baseline thyroid diseases are not at higher risk of contracting or transmitting SARS-CoV-2, and baseline thyroid dysfunction does not foster a worse progression of COVID-19. However, it is unclear whether low levels of free triiodothyronine, observed in seriously ill patients with COVID-19, may worsen the disease's clinical progression and, consequently, if triiodothyronine supplementation could be a tool for reducing this burden. Glucocorticoids and heparin may affect thyroid hormone secretion and measurement, respectively, leading to possible misdiagnosis of thyroid dysfunction in severe cases of COVID-19. High-risk thyroid nodules require a fine-needle aspiration without relevant delay, whereas other non-urgent diagnostic procedures and therapeutic interventions should be postponed. DISCUSSION: Currently, we know that SARS-CoV-2 could lead to short-term and reversible thyroid dysfunction, but thyroid diseases seem not to affect the progression of COVID-19. Adequate management of patients with thyroid diseases remains essential during the pandemic, but it could be compromised because of healthcare service restrictions. Endocrine care centers should continuously recognize and classify priority cases for in-person visits and therapeutic procedures. Telemedicine may be a useful tool for managing patients not requiring in-person visits.

ABSTRACT

In this article, the authors propose a specific Myofunctional Therapy Protocol for patients with altered lingual frenulum. In such cases tongue muscles are hypofunctioning and their range of motion is reduced. To compensate for this limitation, dysfunctional lingual motor patterns are established, such as the use of some muscles at the expense of others; this negatively affects the development and functions of the stomatognathic system. The Myofunctional Therapy Protocol presented in this pilot study was developed with the aim of making the muscles of the tongue, the floor of the mouth and the soft palate more coordinated, and increasing muscle contraction strength, in order to produce improvements on the muscle tone, on orofacial and nasal functions and a better wound healing and functional recovery in the case of surgical therapy (frenulotomy).

ABSTRACT

In this manuscript we aimed at the simultaneous separation and quantification of Gemcitabine and Irinotecan hydrochloride (injected both as single components and in combination) from Sprague Dawley rat plasma by using a validated method obtained through the use of a High Performance Liquid Chromatography (HPLC)-diode array detector (DAD). Gemcitabine and Irinotecan hydrochloride were detected and quantified using a Zorbax Extend C-18 column (250 mm × 4.6 mm; 5 µm particle size) in gradient elution mode. The chromatographic analyses were carried out in 15 min. The analytical mode was calibrated and validated in the concentration range from 0.1 to 18 µg/mL both for Gemcitabine and Irinotecan hydrochloride. Sprague Dawley rat plasma was used to perform the analysis. 3-methylxanthine was the internal standard. The weighted-matrix matched standard curves of Gemcitabine and Irinotecan hydrochloride showed a good linearity up to 18 µg/mL. Parallelism tests were also performed to evaluate whether the over-range samples could be analyzed after dilution without affecting the analytical performance. The intra- and inter-day precision (RSD%) values of Gemcitabine and Irinotecan hydrochloride were ≤7.14% and ≤11.5%, respectively. The intra- and inter-day trueness (Bias%) values were in the range from -11.5% to 1.70% for both drugs. The analytical mode performance was further tested after collecting Sprague Dawley rat plasma following a single-dose administration of chemotherapeutics or their association. The validated HPLC-DAD method allowed the simultaneous quantification of Gemcitabine and Irinotecan hydrochloride in the rat plasma, besides the evaluation of the pharmacokinetic parameters and drug delivery.

ABSTRACT

Magnetic resonance-guided high intensity focused ultrasound (MR-HIFU) has been clinically shown to be effective for palliative pain management in patients suffering from skeletal metastasis. The underlying mechanism is supposed to be periosteal denervation caused by ablative temperatures reached through ultrasound heating of the cortex. The challenge is exact temperature control during sonication as MR-based thermometry approaches for bone tissue are currently not available. Thus, in contrast to the MR-HIFU ablation of soft tissue, a thermometry feedback to the HIFU is lacking, and the treatment of bone metastasis is entirely based on temperature information acquired in the soft tissue adjacent to the bone surface. However, heating of the adjacent tissue depends on the exact sonication protocol and requires extensive modelling to estimate the actual temperature of the cortex. Here we develop a computational model to calculate the spatial temperature evolution in bone and the adjacent tissue during sonication. First, a ray-tracing technique is used to compute the heat production in each spatial point serving as a source term for the second part, where the actual temperature is calculated as a function of space and time by solving the Pennes bio-heat equation. Importantly, our model includes shear waves that arise at the bone interface as well as all geometrical considerations of transducer and bone geometry. The model was compared with a theoretical approach based on the far field approximation and an MR-HIFU experiment using a bone phantom. Furthermore, we investigated the contribution of shear waves to the heat production and resulting temperatures in bone. The temperature evolution predicted by our model was in accordance with the far field approximation and agreed well with the experimental data obtained in phantoms. Our model allows the simulation of the HIFU treatments of bone metastasis in patients and can be extended to a planning tool prior to MR-HIFU treatments.

ABSTRACT

Our aim was to compare the outcome of implants inserted in maxillary sinuses augmented with anorganic bovine bone grafts compared with those augmented with mixed 50:50 bovine and autologous bone grafts. Twenty sinuses with 1-4mm of residual crestal height below the maxillary sinuses were randomised into two groups according to a parallel group design (n=10 in each). Sinuses were grafted using a lateral approach. In one group the grafts were 50:50 anorganic bovine bone and autologous bone and in the other anorganic bovine bone alone. After 7 months, 32 implants had been inserted. Outcome measures were survival of implants, complications, marginal changes in the height of the bone, and soft tissue variables (pocket probing depth and bleeding on probing). Probabilities of less than 0.05 were accepted as significant. No patient failed to complete the trial and no implant had failed at 1 year. There were some minor complications. After 12 months, the mean (SD) marginal bone loss (mm) was 1.06 (0.61) in the 50:50 group and 1.19 (0.53) in the anorganic bovine group. The mean (SD) values for pocket probing depth (mm) and bleeding on probing (score) were 2.49 (0.38) and 1.59 (0.82) in the 50:50 group and 2.31 (0.64) and 1.36 (0.87) in the anorganic bovine group (neither difference was significant). The present data are consistent with the hypothesis that the outcome of implants inserted in sinuses grafted with either material is comparable.

ABSTRACT

Continuity defects in bone after resection of the jaw may cause problems, and osseo-myocutaneous free flaps are the gold standard for their reconstruction. Implant-supported prosthetic rehabilitation is reliable with these microvascular options, although it is still a serious challenge. The aim of this prospective clinical study was to describe the advantages of implants restored according to a computer-assisted surgical protocol. A group of 10 consecutive patients (both sexes) had already been treated and followed up for at least 1 year after prosthetic loading. The NobelGuide protocol had to be modified to adapt the technique for these patients who had had reconstructions. A total of 56 fixtures were installed and, when possible, immediately loaded (overall survival of implants 95%). Every patient was given correct provisional prosthetic rehabilitation, which was most satisfactory as far as chewing, social functioning, and overall quality of life were concerned. Three-dimensional computed tomographic (CT) examination showed a mean (SD) marginal bone loss of 1.06 (0.5)mm. We used a modified technique of computer-assisted implant surgery in jaws that had been reconstructed with free flaps; from these preliminary findings this approach seems valid when it comes to function, improving prosthetic restoration, and aesthetics.

ABSTRACT

OBJECTIVE: To analyze the differences in anatomical, clinical and echocardiographic characteristics of women and men undergoing PMV and to evaluate the relationship between sex, PMV success, and immediate and long-term clinical outcome. BACKGROUND: Rheumatic mitral stenosis (MS) is predominantly a disease of middle-aged women. Percutaneous mitral valvuloplasty (PMV) has become the standard of care for suitable patients. However little is known about the relationship between sex, PMV success, and procedural outcome. METHODS AND RESULTS: We evaluated measures of procedural success and clinical outcome in consecutive patients (839 women and 176 men) who underwent PMV. Despite a lower baseline echocardiographic score (7.47 ± 2.15 vs. 8.02 ± 2.18, P = 0.002), women were less likely to achieve PMV success (69% vs. 83%, adjusted OR 0.44, 95% CI 0.27-0.74, P = 0.002), and had a smaller post-procedural MV area (1.86 ± 0.7 vs. 2.07 ± 0.7 cm(2), P < 0.001). Overall procedural and in-hospital complication rates did not differ significantly between women and men. However, women were significantly more likely to develop severe MR immediately post PMV (adjusted OR 2.41, 95% CI 1.0-5.83, P = 0.05) and to undergo MV surgery (adjusted HR 1.54, 95% CI 1.03-2.3, P = 0.037) after a median follow-up of 3.1 years. CONCLUSIONS: Compared to men, women with rheumatic MS who undergo PMV are less likely to have a successful outcome and more likely to require MV surgery on long-term follow-up despite more favorable baseline MV anatomy.

ABSTRACT

Dental pulp is a heterogeneous microenviroment where unipotent progenitor and pluripotent mesenchymal stem cells cohabit. In this study we investigated whether human dental pulp stromal (stem) cells (DP-SCs) committed to the angiogenic fate. DP-SCs showed the specific mesenchymal immunophenotypical profile positive for CD29, CD44, CD73, CD105, CD166 and negative for CD14, CD34, CD45, in accordance with that reported for bone marrow-derived SCs. The Oct-4 expression in DP-SCs, evaluated through RT-PCR analysis, increased in relation with the number of the passages in cell culture and decreased after angiogenic induction. In agreement with their multipotency, DP-SCs differentiated toward osteogenic and adipogenic commitments. In angiogenic experiments, differentiation of DP-SCs, through vascular endothelial growth factor (VEGF) induction, was evaluated by in vitro matrigel assay and by cytometric analysis. Accordingly, endothelial-specific markers like Flt-1 and KDR were basally expressed and they increased after exposure to VEGF together with the occurrence of ICAM-1 and von Willebrand factor positive cells. In addition, VEGF-induced DP-SCs maintained endothelial cell-like features when cultured in a 3-D fibrin mesh, displaying focal organization into capillary-like structures. The DP-SC angiogenic potential may prove a remarkable tool for novel approaches to developing tissue-engineered vascular grafts which are useful when vascularization of ischemic tissues is required.

ABSTRACT

BACKGROUND: In amnestic mild cognitive impairment (aMCI), functional neuronal connectivity may be altered, as suggested by quantitative EEG and neuroimaging data. In young healthy humans, the execution of linguistic tasks modifies the excitability of the hand area of the dominant primary motor cortex (M1(hand)), as tested by transcranial magnetic stimulation (TMS). We used TMS to investigate functional connectivity between language-related cortical areas and M1(hand) in aMCI. METHODS: Ten elderly women with aMCI and 10 age-matched women were recruited. All participants were right handed and underwent a neuropsychological evaluation. In the first TMS experiment, participants performed three different tasks: reading aloud, viewing of non-letter strings (baseline), and nonverbal oral movements. The second experiment included the baseline condition and three visual searching/matching tasks using letters, geometric shapes, or digits as target stimuli. RESULTS: In controls, motor evoked potentials (MEP) elicited by suprathreshold TMS of the left M1(hand) were significantly larger during reading aloud (170% baseline) than during nonverbal oral movements, whereas no difference was seen for right M1(hand) stimulation. Similarly, MEP elicited by left M1(hand) stimulation during letter and shape searching/matching tasks were significantly larger compared to digit task. In contrast, linguistic task performance did not produce any significant MEP modulation in patients with aMCI, although neuropsychological evaluation showed normal language abilities. CONCLUSIONS: Findings suggest that functional connectivity between the language-related brain regions and the dominant M1(hand) may be altered in amnestic mild cognitive impairment. Follow-up studies will reveal whether transcranial magnetic stimulation application during linguistic tasks may contribute to characterize the risk of conversion to Alzheimer disease.

ABSTRACT

Three-dimensional reconstruction of the anterior mouth floor and ventral tongue after ablative surgery can be achieved using several techniques. The ideal reconstruction should be accomplished with the same or similar type of tissue, and cheek axial myomucosal flaps based on the branches of facial or internal maxillary arteries seem ideal for this purpose. From March 2005 to May 2007, 23 patients underwent cheek axial myomucosal flap reconstruction after oral cancer surgical ablation. Thanks to their thinness and pliability, these flaps were frequently shaped to obtain an accurate reconstruction. According to Whetzel's hypothesis, an intraoral flap designed to include the axial vessel of one area can safely carry the mucosa of a neighbouring vascular area. The authors describe a large buccinator myomucosal island flap based on the branches of the facial artery and formed in a trilobed shape in order to capture the adjacent buccal mucosal angiosome from the internal maxillary artery. The flap provided the correct anatomical oral reconstruction for the anterior mouth floor and ventral tongue. The function of the tongue, oral intake and mastication were not impaired. The trilobed buccinator myomucosal island flap is a suitable option for the three-dimensional reconstruction of the anterior mouth floor and ventral tongue.

ABSTRACT

The reconstruction of large maxillofacial defects generally requires harvesting bone from extra-oral sites. The main source of autogenous bone is the iliac crest. This donor site is used to obtain bone for augmentation in orthopaedic surgery, neurosurgery, and oral and maxillofacial surgery, where the main indications are secondary and tertiary osteoplasty in patients with cleft-lip and palate, reconstruction of bony defects after operations for tumours, and augmentation of severe atrophy of the alveolar crest in preprosthetic surgery. A review of the literature on complications following bone harvesting from the anterior iliac crest reveals persistent pain, nerve injury, haemorrhage, limping, persistent gait abnormalities, conspicuous scarring, bone contour alteration, infection, fracture, meralgia paraesthetica, peritonitis, and herniation. The authors report an unusual complication: a huge iliac abscess that appeared 4 years after bimaxillary surgery involving iliac bone grafts.

ABSTRACT

Nowadays, microsurgery performed for oral reconstruction of cancer patients, has become the standard treatment in restoring oral functions. The free radial forearm flap (FRFF) is still apparently the first reconstructive choice in oral cavity cancers. Recently the anterolateral thigh flap (ALTF) seemed to challenge the superiority of FRFF. The lack of functional data on which to base this recent supposition is the reason for this new research. Twenty reconstructed patients were enrolled for this study. Speech, swallowing, and donor site complications were studied to assess differences between the two techniques. Results show that difference in function between ALTF and FRFF groups is statistically insignificant. Donor site risks and complications seem to be the only variables among groups. These variables may be used as indicators when making a surgical choice.

ABSTRACT

Soft-tissue chondroma is an infrequent, benign, cartilaginous tumour that is uncommon in the head and neck region. Single-location chondromas rarely evolve into malignant neoplasms. Chondromas are composed of hyaline cartilage with focal calcification. There have been a few reports published of cases of soft-tissue chondroma of the neck and parapharyngeal space. Here is described a new location of this tumour in the masticatory space.

ABSTRACT

AIM: The study evaluates the repair of residual alveolar cleft through secondary bone graft, consisting in the transplantation of autologous bone to restore the continuity of the maxillary arch and achieve normal functioning and esthetics. METHODS: During 2001-2002, 15 patients (age range 9-26 years; 7 males, 8 females) were submitted to secondary bone graft at the Maxillo-facial Surgery Operative Unit, University Hospital, Sassari. Eleven patients had complete unilateral cleft, 4 had complete bilateral cleft. All patients were operated upon by the same surgeon; they received a graft of autologous bone from the iliac crest. For preoperative and postoperative evaluation at 1 year, the following were utilised: plaster casts of the tooth arches, OPT, photographs and complete clinical documentation. RESULTS: Postoperative results were: 100% formation of a bone bridge between the maxillary segments; 70% closure of oro-nasal fistula; 100% maxillary stability; 80% spontaneous eruption of the canine within the graft; 70% height of alveolar ridge level I, 25% level II, 5% level III; 70% orthodontic closure; 80% optimal periodontal condition and 20% presence of gingival recession. In 1 subject the graft site became infected, in 4 cases an oro-nasal fistula remained. CONCLUSION: This method was found to be the most valid one at present. The best period to intervene is during late childhood (9 years). Results and functional and esthetic recovery were satisfactory and encouraging to continue utilising this technique.

ABSTRACT

Synovial sarcoma is an uncommon neoplasm accounting between 8 and 10% of all soft tissue malignancies. Involvement of the head and neck region is rare. So far, fewer than 100 cases have been reported in the literature and only a few originated in the soft palate, tongue, larynx, hypopharynx, and cervical oesophagus. We report the case of a synovial sarcoma of the parapharyngeal space in a 72-year-old female, and experience in the behaviour and surgical treatment of this neoplasm is described. The patient has remained disease free for 28 months, with regular follow-up. Based upon this case and the others reported in the literature, synovial sarcoma does not have a good overall prognosis, and on account of its rarity and unpredictable biologic behaviour, surgical excision, and regular clinical and radiographic follow-up for at least 3 years are strongly recommended.

ABSTRACT

BACKGROUND: After a review of the literature, the results of a clinical study carried out on cases of extracranial arteriovenous malformations of the head and neck, are reported. METHODS: Thirteen patients with extracranial arteriovenous malformations of the head and neck have been treated at the Maxillofacial Department of the University of Parma from 1995 to 2000. Five patients observed the onset in childhood, five in adolescence and three in adulthood. Arteriovenous malformations have been classified according to Schobinger's clinical staging. Four patients with superselective embolization, one with surgical resection and the remaining eight with superselective embolization followed by radical en bloc resection have been treated. The follow-up period varied from 2 to 5 years. RESULTS: No relapses have been observed in the cases treated with surgical resection and with superselective embolization followed by radical excision. Only 1 patient treated by superselective embolization had a good outcome. This treatment can be a good palliative in the treatment pain and bleeding particularly when surgical excision would result in mutilation or disfigurement, nevertheless it is necessary a careful follow-up since the lesion treated only by superselective embolization can grow quickly and begin bleeding and aching again. CONCLUSIONS: In personal experience, according to the literature, embolic/surgical management of arteriovenous malformations is not always the treatment of choice. On the basis of clinical characteristics of the lesions, different kinds of treatments (embolization, resection, embolization followed by resection) may be chosen to obtain favorable RESULTS.
