RESUMO
BACKGROUND AND OBJECTIVES: Among orbital tumors, metastatic lesions have a prevalence of 1% to 13%; on the other hand, breast cancer is the most common malignancy causing orbital metastases. The aim of this study is to present our experience dealing with orbital metastases caused by breast cancer, to assess characteristics and clinic-pathological data of patients suffering from this rare occurrence and to find indexes related with their prognosis and survival. METHODS: Records of 28 patients diagnosed with orbital metastases from breast cancer at the Department of Ophthalmology, Humanitas Clinical and Research Centre of Milano over a 27-year period (1992-2018) were retrieved and analyzed. RESULTS: Mean patients' age at breast cancer diagnosis was 56.29 ± 14.63 years. Mean time interval between breast cancer diagnosis and orbital metastasis occurrence was 5 ± 4.17 years. All lesions were estrogen receptor-positive; 79% of patients harbored progesterone receptor-positive lesions. Interestingly, the majority of deceased patients presented orbital lesions with MIB-1 index >50% (P = .0265) and had concomitant lung metastases (P = .0452). CONCLUSIONS: The occurrence of orbital metastasis from breast cancer represents a challenging finding. Patients' clinical picture can include exophthalmos, edema, tumefaction, proptosis and/or diplopia. Significant symptomatic improvement can be achieved through surgery and other adjuvant treatments, such as radiation therapy and chemotherapy.

TBI is the main cause of death and disability in individuals aged 1-45 in Western countries. One of the main challenges of TBI at present is the lack of specific diagnostic biomarkers, especially for mild TBI (mTBI), which remains currently difficult to value in clinical practice. In this context MiRNAs may be important mediators of the profound molecular and cellular changes that occur after TBI in both the short and the long term. Recently, plasma miRNAs profiling in human TBI, have revealed dynamic temporal regulation of miRNA expression within the cortex. Aim of this study was to select a specific miRNAs panel for mTBI, by focusing the research on the prognostic meaning of miRNAs in the hours following the trauma, in order to be able to use this MIRNAs as potential biomarkers useful for monitoring the follow up of mild TBI. Serum levels of 17 miRNAs were measured by RT-quantitative polymerase chain reaction (qPCR) in 20 patients with mTBI at three different time-points (0 h, 24 h, 48 h) and in 10 controls. For 15 miRNAs we found a significant differences in the comparison among the three time points: for each of these miRNAs the values were greater at baseline and progressively reduced at 24 h and 48 h. These data allow us to consider the miRNAs included in panel as sensitive and specific biomarkers for mTBI, useful in monitoring the post-trauma period.

This prospective study evaluated the intraoperative ultrasound scan (IUSS) for nonpalpable breast lesions' detection. A total of 108 consecutive female patients underwent surgery using IUSS: Frozen sections demonstrated clear margins in 95.5% of neoplastic patients. Only four (4.5%) patients underwent local re-excision in the same operation. IUSS demonstrated to be quick, accurate, useful, effective, and safe for the intraoperative management of neoplastic nonpalpable breast lesions when performed by a surgeon who has undergone US training, particularly for people in whom alternative approaches can show some limitations due to contraindications or because of scheduling constraints, costs, and patient discomfort.

PURPOSE: The role of augmented internal anal sphincter (IAS) tone in the genesis of posterior chronic anal fissure (CAPF) is still unknown. Lateral internal sphincterotomy is the most employed surgical procedure, nevertheless it is burdened by high risk post-operative anal incontinence. The aim of our study is to evaluate results of sphincter saving procedure with post-operative pharmacological sphincterotomy for patients affected by CAPF with IAS hypertonia. Methods: We enrolled 30 patients, undergone fissurectomy and anoplasty with V-Y cutaneous flap advancement; all patients received topical administration of nifedipine 0.3% and lidocaine 1.5% ointment-based therapy before and for 15 days after surgery. The primary goal was patient's complete healing and the evaluation of incontinence and recurrence rate; the secondary goal included the evaluation of manometry parameters, symptom relief and complications related to nifedipine and lidocaine administration. Results: All wounds healed within 40 days after surgery. We didn't observe any de novo postoperative anal incontinence case. We reported 2 cases of recurrences, healed after conservative therapy. We didn't report any local complications related to the administration of the ointment therapy; with whom all patients reported a good compliance. Conclusions: Fissurectomy and anoplasty with V-Y cutaneous advancement flap and topical administration of nifedipine and lidocaine, is an effective treatment for CAPF with IAS hypertonia.

Background: Development of seroma after incisional hernia repair is a common complication. Our study aims to compare the outcomes of sublay incisional hernia repairs with or without spray instillation of fibrin glue. Methods: We enrolled fifty patients undergoing incisional hernia repair. In all patients a suction drain was placed in the subcutaneous space. In one group (FG) 4 ml fibrin glue was instilled in the subcutaneous space. In the control group (C) patients did not receive any prevention measure. Wounds fluids were collected on post-operative day 1 (POD) and once daily until drain removal. All patients were followed up by ultrasound on POD 15, 20, 40, 60. Results: Drain fluid production, even if in significantly greater amount in the C group (p 0.01) as compared with the FG group, decreased after POD 1 in both groups. Drain was removed on POD-5 in 80% of FG patients and in 36% of C patients (p 0.01). No infective or bleeding complications were detected. In group FG average hospital stay was of 5.5 ÃÂ+- 2 days versus 7.1 +- 1.5 days in group C (p 0.01). At ultrasounds examination, seroma development was similar among two groups. Conclusions: Spray instillation of fibrin glue during the surgical repair reduces amount of drained fluid and hospital stay without increasing surgical complications. However, seroma occurrence was not significantly reduced.

Transoral endoscopic thyroidectomy by vestibular approach (TOETVA) represents an innovative and scarless technique for thyroid surgery. The procedure is conducted via a three-port technique at the oral vestibule using a 10mm port for the 30° endoscope and two additional 5mm ports for the dissecting and coagulating instruments. Patients meeting the following criteria can be considered as candidates for TOETVA: (a) an ultrasonographically (US) estimated thyroid diameter =10cm; (b) US-estimated gland volume =45mL; (c) nodule size =50mm; (d) presence of a benign tumor, such as a thyroid cyst or a single- or multinodular goiter; (e) Bethesda 3 and/or 4 categories, and (f) papillary microcar-cinoma without the evidence of metastasis. Beyond the classic complications of thyroid surgery, namely cervical hematoma, recurrent laryngeal nerve injury and hypoparathyroidism, novel consequences can occur as mental nerve (MN) injury. In this paper, leading experts in the field report on their current clinical experience with the TOETVA approach for thyroid gland surgery, with emphasis given to tips and tricks to avoid and manage MN injury.

The aim of the present investigation was to systematically analyse the literature on the facial bone reconstruction defect using marine collagen or not and to evaluate a predictable treatment for their clinical management. The revision has been performed by searched MEDLINE and EMBASE databases from 2007 to 2017. Clinical trials and animal in vitro studies that had reported the application of bone substitutes or not for bone reconstruction defect and using marine collagen or other bone substitute material were recorded following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The first selection involved 1201 citations. After screening and evaluation of suitability, 39 articles were added at the revision process. Numerous discrepancies among the papers about bone defects morphology, surgical protocols, and selection of biomaterials were found. All selected manuscripts considered the final clinical success after the facial bone reconstruction applying bone substitutes. However, the scientific evidence regarding the vantage of the appliance of a biomaterial versus autologous bone still remains debated. Marine collagen seems to favor the dimensional stability of the graft and it could be an excellent carrier for growth factors.

INTRODUCTION: Parathyroid autotransplantation is an easy procedure with a low complication rate. We adopted the transplantation into the sternocleidomastoid muscle, which allows an easier and time-saving surgical procedure using the same surgical incision. METHODS: In this study, we retrospectively reviewed the records of 396 consecutive patients, who underwent total thyroidectomy for benign thyroid disease. In all cases in which a parathyroid was damaged or inadvertently removed, the gland was transplanted; before the autotransplantation, the parathyroid tissue was put in a cell culture nutrient solution for 5 min, afterward fragmented, and then was transplanted in the sternocleidomastoid muscle. To demonstrate a beneficial effect of the cell nutrient solution step, we compared data of transplanted patients with a control group of cases (n = 190) undergoing a standard immediate autotransplantation. RESULTS: We divided patients in two main groups: group A (n = 160) including subjects that underwent one or more parathyroid gland autotransplantation using the cell nutrient solution, and group B (n = 236) concerning those who were not transplanted. Among patients, 62 hypocalcemias occurred, 40 in the group A and 22 in the group B (P < 0.001): 91.9 % were transient and 8.1 % (5 patients) definitive, all pertaining to the group B. Among controls (group C), 42 hypocalcemias occurred (P = 0.616 vs. group A and P = 0.002 vs. group B) and 3/42 became definitive (P = 0.096 vs. group A and P = 0.121 vs. group B). All differences concerning pre- and postoperative calcium values were statistically significant (P < 0.001). CONCLUSIONS: We recommend the routine parathyroid autotransplantation, when a vascular damage is certain or suspected, in order to reduce the rate of permanent hypoparathyroidism, using a cell culture nutrient solution before gland transplantation.

Multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS) are two different central nervous system pathology that, according to the most accredited hypotheses, recognize a different etiopathogenesis. The simultaneous occurrence of MS and ALS is quite unusual. To our knowledge, only three cases have been so far described by clinical, laboratory, and post-mortem studies. We report four new cases of this peculiar combination that have been observed and are herein described, included their human leukocyte antigen (HLA) profile studies. On the basis that three out of four patients in our case series presented HLA-B*18:01A, we may hypothesize that this antigen could play a role in developing both diseases.

Simultaneous performance of motor and cognitive tasks may compete for common brain network resources in aging or patients with some neurological diseases, suggesting the occurrence of a cognitive-motor interference. While this phenomenon has been well described for multiple sclerosis (MS) patients, it never has been tested on asymptomatic subject with magnetic resonance imaging (MRI) findings suggestive of demyelinating disease (i.e., radiologically isolated syndrome: RIS). In this pilot study, 10 RIS subjects and 10 sex/age-matched healthy controls were tested by means of static posturography under eyes opened (single-task trial) and while performing two different cognitive tasks (semantic modified word list generation for first dual-task trial and phonemic semantic modified word list generation for second dual-task trial), to estimate the dual-task cost (DTC) of standing balance. In our sample, under cognitive interference (without any substantial differences between semantic and phonemic modified word list generation), the RIS group showed significance differences in CoP (center of pressure) total sway area, ellipse eccentricity, CoP sway path length, CoP median sway velocity along the AP (anteroposterior) axis and along the ML (mediolateral) axis, reflecting a higher negative DTC respect to healthy subjects (which have simply shown a statistical trend, failing to reach a significance, in some trials). The phenomenon of cognitive-motor interference might be unmasked by a dual-task posturography in RIS subjects, too. We hypothesize that this approach could be useful to early reveal the presence of a demyelinating disease and to reach a MS diagnosis in subjects otherwise classified as RIS.

The aim of this paper is to underline the mechanical properties of dental single crown prosthodontics materials in order to differentiate the possibility of using each material for typical clinical condition and masticatory load. Objective of the investigation is to highlight the stress distribution over different common dental crowns by using computer-aided design software and a three-dimensional virtual model. By using engineering systems of analyses like FEM and Von Mises investigations it has been highlighted the strength over simulated lower first premolar crowns made by chrome cobalt alloy, golden alloy, dental resin, and zirconia. The prosthodontics crown models have been created and put on simulated chewing stresses. The three-dimensional models were subjected to axial and oblique forces and both guaranteed expected results over simulated masticatory cycle. Dental resin presented the low value of fracture while high values have been recorded for the metal alloy and zirconia. Clinicians should choose the better prosthetic solution for the teeth they want to restore and replace. Both prosthetic dental crowns offer long-term success if applied following the manufacture guide limitations and suggestions.

PURPOSE: Maxillofacial injuries are frequently associated with multiple trauma and can determine functional and aesthetic bad outcomes. The severity of maxillofacial injuries may be considerable and can divert clinicians' attention from other concomitant injuries which is less evident but potentially life-threatening. The aim of this study was to find out the concomitant injuries in patients referred to the Emergency Department (ED) of the University Hospital of Messina (North-East Sicily, Italy) for maxillofacial traumas. METHODS: We retrospectively evaluated data of 240,833 patients admitted at the ED of the University Hospital of Messina from January 2008 to December 2015 because of maxillofacial injuries leading to hospitalization and surgical treatment. Patients who primarily received treatment care at different institutions, pediatric trauma patients and adult patients who were transferred in accordance with pre-existing agreements in case of paucity of beds were excluded. Finally we included 447 (0.2%) patients over the 8 years. Data were evaluated with emphasis on epidemiology (age, gender, mechanism of trauma), primary survey and abnormalities and pattern of trauma. RESULTS: The most frequent cause of maxillofacial trauma was road accidents (319 patients, 71.4%), among which motorcycle ones were prevalent. The maxillofacial injured who presented major lesions were 98 patients and minor lesions occurred in 349 patients; 443 (99.1%) patients underwent maxillofacial surgery, immediate or delayed depending on the severity of concomitant injuries (χ2 = 557.2, p < 0.0001). Five concomitant neglected lesions were found to be associated with severe maxillofacial traumas (χ2 = 17.13, p < 0.0001 vs minor lesions). All of the neglected lesions occurred in paucisymptomatic patients who showed painless abdomen, no hemodynamic instability, no signs of hematoma of anterior and posterior abdominal wall or other suspicious clinical signs and symptoms. CONCLUSION: Among the patients admitted firstly in other surgical wards different from the Maxillofacial Surgery Unit, diagnosis was more difficult, especially for blunt abdominal traumas, in which patients showed only vague and nonspecific symptoms concealing serious and life-threatening injuries. We recommend the routine use of whole body CT scan, when the maxillofacial injuries appear prevalent, mainly in patients affected by maxillofacial major lesions.

Penetrating cervical lesions caused by a foreign body are rare events. The neck is a complex and delicate body region, given the important vascular structures it holds. The most frequent fatal complications often involve vascular injuries, and as a consequence, the mortality rate increases by approximately 50%. Civilian patients are mainly victims of violence or motor vehicle accidents and rural accidents involving neck are not very common. When a cervical lesion is because of a wooden foreign body, infectious risk increases for its organic peculiarity. The authors report a rural nonfatal cervical lesion in a civilian, and its management.

Cancer anorexia-cachexia syndrome (CACS) is the most frequent paraneoplastic syndrome occurring in half of all oncologic patients and is considered as a poor prognosticator. Patients usually present with weight loss, lipolysis, muscle wasting, anorexia, chronic nausea, inflammation, and asthenia. The etiopathogenesis of CACS is still poorly understood, although several factors and biological pathways are known to be involved. Because of the complexity of this multifactorial condition, a single agent therapy may not be sufficient. Indeed, there is a tendency toward an integrated multiple approach including nonpharmacological and pharmacological treatments. However, despite encouraging preliminary results, currently there is not enough evidence to support a change in clinical practice. This review provides a brief and practical summary of the diagnosis, pathogenesis, and treatment of CACS. Future perspectives will also be discussed.

The medical approach to disasters has been always a problematic issue for emergency departments. The authors of this paper reflect on possible efficient solutions for managing a massive influx of casualties in an Emergency Department, by analysing the responses to previous local catastrophic events, such as the collision of 'Segesta Jet', the great fire of Patti, the floods of Giampilieri/Scaletta and Saponara. The authors' point to a need for providing more extensive training of medical students in clinical aspects of disaster medicine.
