Abstract: Since 1980s, the use of dermal regeneration templates (DRT) for reconstructive purposes has been described in Literature.1 The authors present their experience of 13 patients treated with integra dermal regeneration template and a single-stage surgery for different indications like oncologic reconstruction, trauma injuries, and preprosthetic surgery in the maxillo-facial district.The authors retrospectively reviewed a total of 13 patients treated with DRT at Maxillo-Facial Department of S. Maria Hospital in Terni.Inclusion criteria included the presence of a defect nonapproachable primarily or by secondary intention with an easy locoregional flap reconstruction, a complete clinical record, and a minimum 6 months follow-up.A total of 12 patients underwent surgical reconstruction with DRT at the S. Maria Hospital from June 2018 to February 2020.During follow-up, all patients in which intraoral reconstruction was performed showed first signs of re-mucosization and neovascularization after 10 days.Only in 1 patient (8%) a seroma underneath the silicon sheet was observed. Afterward, the patient healed correctly with no other complications.Dermal regeneration template represents an option that should be considered in the head and neck district reconstruction, especially for intraoral defects where, thanks to its long-term functional results and limited alternatives, should represent a relevant choice., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 by Mutaz B.

- Abstract
: Cocaine is the most commonly used recreational drug among young adults with levels reaching epidemics proportions. This accelerated rate of use is due mainly to easy access and administration, reduced cost, and, importantly, underestimation of the drug risks. Cocaine, instead, is responsible of endothelial dysfunction and accelerated atherosclerosis with consequent organ damage. Cocaine abuse is not only associated with central necrotizing vasculitis, but it is also appeared to play a role in the development of peripheral vasoconstriction with symptoms similar to Buerger's disease. The current study reports a middle-aged man addicted to cocaine for 20 years. The patient presents several cardiovascular disease risk factors and manifestations, including diabetes mellitus and hypertension. Additionally, arteriography showed complete left posterior tibial artery obstruction with distal collateral vessels and severe leftfoot ischemia. For clinical worsening 1 month later, the patient underwent another arteriography. Although angioplasty of posterior tibial artery showed recovery of blood flow, immediately after treatment (selective percutaneous transluminal angioplasty of posterior tibial artery, dilation with balloon without stenting), a return to pretreatment blood flow 2 min later was observed. This transient change was mediated by severe vasospasm resulting in a complete re-obstruction of the vessel. The poor vascular manifestations are most probably due to cocaine-necrotizing vasculitis subsequent to endothelial dysfunction and accelerated atherosclerosis usually associated with cardiovascular risk factors. Therefore, treatments of young cocaine addicts presenting many cardiovascular risk factors and manifestations should always be carefully investigated and cautiously approached, especially in those with poor outcomes.

- Abstract
The authors present a rare patient of right synovial chondromatosis (SC) of the temporomandibular joint in which diagnosis was late and delay led to SC extension to the cranial base. Synovial chondromatosis is a rare benign disorder characterized by multiple cartilaginous free-floating nodules originated from the synovial membrane of large articular joints of the body. Differential diagnosis is with neoplasm and radical surgical removal is essential. The patient came to the authors' observation complaining about long-lasting temporomandibular joint dysfunction. The patient already underwent either functional or medical therapy in times without any improvement. Clinical examination showed limited mouth opening and swelling of the right preauricolar region with no signs of facial nerve palsy and without paresthesia or hearing loss. No history of recent trauma was recorded. Magnetic resonance imaging showed a mucous-like hyperintense mass with small hypointense spots inside. A preoperative computed tomography scan was performed and showed a mass extending from the superior aspect of the temporomandibular joint to the glenoid fossa, which was partially eroded. The patient underwent either open joint surgery or arthroscopy of the superior joint space and a large number of chondrocytes were removed. No complications were recorded postoperatively and the patient completely recovered after 6 months. Histology confirmed the diagnosis of synovial condromatosys of the right temporomandibular joint.

- Abstract
Objectives: Celiac disease (CD) represents a spectrum, which includes cases with minor histological abnormalities (potential CD). The aim of this work is to evaluate the contribution of immunohistochemical analysis of duodenal biopsies to the diagnosis of gluten-related minor enteropathy., Methods: Duodenal biopsies from 56 patients with untreated CD and 56 controls were analyzed for CD3 and γδ intraepithelial lymphocyte number, γδ/CD3 ratio, and density of CD25+ lamina propria cells. A discriminant equation was obtained by which 61 more biopsies with normal villous architecture were blindly evaluated., Results: All of the immunohistochemical parameters were significantly different between patients with CD and controls. None of the single parameters showed sufficient specificity for CD. The combination of all of the 4 markers resulted in the following discriminant equation: discriminant score (Dscore) = (CD3 × 0.06) - (γδ × 0.119) + (CD25 × 0.012) + (γδ/CD3 × 0.131) - 4.709. Using this Dscore, patients were correctly classified as celiac or controls in 97.3% of the cases. When this equation was applied to a validation set of 61 patients with normal villous architecture and unknown diagnosis, 92.9% of those with a positive score turned out to be patients with potential CD. A normal score, however, did not exclude this condition., Conclusions: Immunohistochemistry represents a specific tool for the diagnosis of CD, but does lack sensitivity in detecting all of the potential CD cases.

- Abstract
Objectives: In children younger than 2 years of age, a diagnosis of celiac disease (CD) is difficult to make because anti-endomysium (anti-EMA)/anti-tissue transglutaminase 2 (anti-TG2) antibodies are less sensitive than in older children. The aim of our study was to evaluate how many children younger than 2 years of age and diagnosed with CD, were negative for serum anti-TG2 antibodies and to test the hypothesis that in these patients, TG2-specific IgA deposits could instead be present at mucosal level., Patients and Methods: A total of 104 children younger than 2 years of age and 179 children older than 2 years, all of whom had been diagnosed with CD, were investigated for serum CD-associated antibodies (anti-gliadin [AGA] IgA and IgG, EMA-IgA, anti-TG2-IgA). The presence of intestinal anti-TG2 extracellular IgA deposits was searched by using double immunofluorescence in 56 of the patients younger than 2 years of age and in 40 of those who were older than 2 years., Results: In children with CD who were younger than 2 years of age, high levels of AGA-IgA were found in 93/104 (89%) and 98/104 (94%) were found of have high levels of AGA-IgG. In children older than the age of 2 years with CD, 120/179 (67%) had high levels of AGA-IgA and 151/179 (84%) had high levels of AGA-IgG. Serum EMA were present in 92/104 (88%) in the younger group and in 176/179 (98%) of the older group. Ninety-one of 104 children (87%) younger and 172/179 (96%) older than 2 years showed high serum levels of anti-TG2. Finally, 41/56 (73%) children younger than 2 years and all of the 40 children (100%) older than 2 years of age showed mucosal anti-TG2-IgA deposits., Conclusions: EMA and anti-TG2-antibody measurements show higher sensitivity for the diagnosis of CD in children older than 2 years compared with younger children. The search for mucosal deposits of anti-TG2-IgA does not improve the diagnostic performance.

- Abstract
Objectives: Anti-tissue transglutaminase (anti-TG2) immunoglobulin A (IgA) autoantibodies are detectable in the serum of most patients with untreated celiac disease (CD). Their deposits in the intestine of patients with CD with severe enteropathy are considered specific for this condition. The histological spectrum of CD includes cases with normal villous architecture. The aim of this study was to look for anti-TG2 IgA deposits in the intestine of children with normal villous architecture and to relate them with other markers of gluten sensitivity., Patients and Methods: A total of 57 children with normal duodenal villous architecture and markers of gluten sensitivity were considered. Of those, 39 showed positive serum anti-endomysium antibodies and/or high levels of anti-TG2 antibodies (group 1), and 18 were seronegative with only a greater density of gammadelta intraepithelial lymphocytes (group 2). Thirty-four children with no markers of gluten sensitivity and a normal mucosa represented the control group (group 3). The duodenal sections of all patients were investigated for deposited anti-TG2 IgA by double immunofluorescence. Human lymphocyte antigen molecular typing was performed., Results: In group 1 and in group 2, 33 of 39 children (85%) and 12 of 18 children (66%) showed subepithelial anti-TG2 IgA intestinal deposits, respectively. Only in 3 of 34 (8.8%) children with no markers of gluten sensitivity were anti-TG2 IgA deposits noted., Conclusions: A subgroup of children with no serum CD-associated autoantibodies, but greater density of gammadelta intraepithelial lymphocytes, shows a clear anti-TG2 IgA deposition in the duodenal mucosa. These children must be investigated further for possible gluten sensitivity.

- Abstract
Chronic recurrent temporomandibular joint (TMJ) dislocation is defined as the complete loss of articular relationships, during mouth-wide opening, between the articular fossa of the temporal bone and the condyle-disk complex. The most frequent pathogenetic factors involved in chronic recurrent dislocation of the TMJ are supposed to be trauma, abnormal chewing movements, TMJ ligaments, capsule laxity, and masticatory muscles disorders. In fact, TMJ dislocation occurs more frequently in people with general joint laxity and in patients with internal derangement of the TMJ or with occlusal disturbance. Management of TMJ dislocation remains a challenge. Eminectomy, whose validity has been demonstrated by several authors, acts on the bony obstacle, preventing condylar locking, but does not have a therapeutic effect on TMJ ligament and capsular laxity or masticatory muscle incoordination, which seem to be the real cause of TMJ dislocation in most cases. The authors present a mini-invasive modified technique of eminectomy, which aims to act on both the obstacle and the cause with respect and restoration of TMJ biomechanical constraints.

- Abstract
The authors historically review bibliographic research concepts and define globalization in time. Moreover, recent free online data exchange is important in terms of medical progress, scientific updating and patient-care improving. In the author's opinion, data globalization is favoring medical knowledge flow even more. The concept of a traditional library has radically changed over time, gradually missing their pivotal role in research activity. To date, the birth of the Internet and its sudden development has given a great boost to the spread of worldwide information, quickly and cheaply. Nevertheless, besides the advantages, the Internet also hides misleading risks. In this paper, the professional Medline source is compared to common Internet sources. The authors state that Internet sources have a great importance in the spread of medical knowledge. They conclude, however, that the risk of too much available information could lead to a decrease in quality.

- Abstract
Objective: Chronic gastrointestinal symptoms and histologic changes of the esophagus unresponsive to standard treatments for gastroesophageal reflux disease (GERD) may be improved by the use of elemental formulas. The aim of our study was to evaluate the efficacy of a dietary trial in neurologically impaired children unresponsive to medical and surgical therapy for GERD., Methods: Nine children (three boys and six girls; median age, 44 months; range, 13-180 months) affected by cerebral palsy associated with severe mental retardation and with long-standing history of GERD were fed the elemental formula, Neocate, for a minimum of 4 weeks. Before and after the dietary trial, each child underwent endoscopy with esophageal biopsy and a cellobiose/mannitol sugar permeability test. The diagnosis of GERD was based on the microscopic changes of the esophagus., Results: Before the dietary trial, according to conventional histologic criteria, esophagitis was considered moderate in seven children and mild in two. Five of nine patients also had abnormal sugar permeability test results. During and after the dietary trial, seven of nine patients experienced resolution of their long-term symptom complaints. Furthermore, after the dietary trial, both endoscopic ( < 0.01) and histologic ( < 0.05) findings significantly improved. At 6-month follow-up, progressive reintroduction of individual dietary proteins, except for cow's milk protein, did not cause reappearance of the symptoms., Conclusions: In neurologically impaired children unresponsive to conventional antireflux treatments, a course of a highly restricted diet with an amino acid-based formula may bring an immediate and sustained, endoscopically and histologically proven improvement in long-standing gastrointestinal symptoms and esophagitis.
