OBJECTIVE: In Europe, a great number of investigations and studies followed up to develop safer techniques performed by physicians only. Successful dedicated medical protocols included the implant of single fibers with ex- tractable root. The aim of our study was to evaluate the efficacy of biocompatible artificial hair implants in patients with androgenetic alopecia. PATIENTS AND METHODS: 682 patients (488 males and 184 females) aged between 25 and 70 years old, with diagnosed AGA, requiring no invasive nor surgical hair restoration, with problems of baldness and refusing surgical options appealed to the Second Opinion Medical Consulting (Modena, Italy), and were included in the present protocol. Before the treatment, all patients underwent a test implant to rule out hypersensitivity by implanting 100 fibers on a selected skin spot. If no reaction was detected, five weeks later 5001,200 fibers were further implanted per session at a minimum interval of 5 weeks until the required aesthetic result was achieved. RESULTS: The average number of sessions for each patient was 5. The average number of implanted fibers was 2,100 (ranging from 800 to 12,000). The treated scalp area returned to normal appearance and tenderness in 3 days. CONCLUSIONS: The socio-phycological benefit and the life quality improvement of our patients have been the focus of the study. On our side, the accurate selection, small hair units for each implant session, customized dermatological consultation and the use of highly biocompatible fibers have been the proper strategy to achieve the goal.

BACKGROUND: In parallel with the increase in requests for filler injections, reported complications (immediate or delayed and transient or permanent) increased too. CASE REPORT: In the presented case report, a patient reported a delayed complication of filler injection. The complaints of the patient and the objective evaluation revealed the presence of multiple lip nodules, that were painful both spontaneously and at the touch, after 10 years from a lip filler injection. The surgical excision of the neoformations permitted the complete healing of the lesions. The histological analysis showed a not specific pattern, showing a material encapsulated by a tissue reaction, confirming that the possible cause of the multiple injuries could be attributable to the injection received years earlier. CONCLUSIONS: The professional who intends to perform filler injections needs a complete training process, both from a theoretical and practical point of view. Also, the patients must be informed of the possible risks associated with each product. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To contribute toward the identification of population-based clinical and histopathological profile of oral squamous cell carcinoma (OSCC), this study was undertaken at the Regional Cancer Centre of Odisha (AHRCC), India. PATIENTS AND METHODS: This retrospective study included all patients diagnosed with OSCC registered at AHRCC, Odisha from 1st January 2015 to 31st December 2018. Demographic, clinical, and pathological data of each patient were retrieved from patient records. Patients with incomplete records were excluded. No postoperative treatment details were collected. RESULTS: The study included 851 cases of OSCC with the mean age of the population found to be 53.8±14.2 years. Male to female ratio was found to be 2.18:1. Gingivobuccal complex was the most common site of OSCC. While 679 patients were reported to undergo incision biopsy only 172 patients underwent excision biopsy in four years. Well differentiation (n=782) is the most common histological grading. The median clinical size of the tumour was 4 cm. Upon analyzing histological parameters in excision specimens lymphovascular and perineural invasion were seen in 38 and 26 cases, respectively. Cervical lymph node metastasis was seen in 42 cases out of 172 excision specimens (24%). 63.23% of cases presented with a depth of invasion between 5 to 10 mm. CONCLUSIONS: This is the largest comprehensive data from the regional cancer center of Odisha population which highlights the demographic, clinical, and histopathological data reported to date.

OBJECTIVE: Treacher Collins syndrome (TCS) is a rare congenital disorder of craniofacial development. TCS occurs with an incidence of 1:50,000, and more than 60% of TCS cases have no previous family history and arise as the result of de novo mutations. The high rate of de novo mutations, together with the extreme variability in the degree to which individuals can be affected, makes the provision of genetic counseling extremely complicated. Consequently, every case of TCS is unique and needs to be assessed individually. Patients with TCS frequently undergo multiple reconstructive surgeries from birth through adulthood, which rarely are fully corrective in the long-term. The nascent field of regenerative medicine offers the promise to improve some of these treatments. In particular, structural fat grafting (SFG) seems to be a good strategy not only to restore the normal volume and contour of the face, but also to provide a source of adipose-derived stem cells (ADSCS) with a multilineage differentiation potential. In this work, we present genetical analyses of AD-SC affected by TCS. MATERIALS AND METHODS: ADSCs from were analyzed for their stemness properties and shared many characteristics with those of a healthy subject. Screening of the genome of the TCS patient using array-Comparative Genomic Hybridization allowed us to identify some chromosomal imbalances that are probably associated with TCS. RESULTS: We found that some alterations, involving the TIMELESS gene, were usually associated with embryonic stem cells. CONCLUSIONS: With the aim to improve the final results, we need to consider combining knowledge of genetic alterations and expression profiles as a fundamental step before starting with surgical procedures.

OBJECTIVE: Recently, Zirconia and polyaryletherketone (PEEK) have attracted increasing interest as reliable and safe materials in dental applications, mainly because of their good biomechanical characteristics. The aim of this study was to investigate the response to different loads by prosthetic frameworks for supported fixed partial dentures (FPDs), thus simulating osseointegrated implants. MATERIALS AND METHODS: The specimens were divided into two groups (n= 5 each). Group A: FDPs in zirconia-ceramic; Group B: FDPs in PEEK-composite. These 2 groups were subjected to vertical loads so to evaluate structural deformation; then, they have been analyzed by scanning electron microscopy (SEM) at different magnifications. RESULTS: In tested samples, different types of mechanical failures have been observed. In Zirconia-specimens, chipping is the main failure noticed in this study, mostly in distal margins of the structure. Also, peek-specimens show failure and fracture. CONCLUSIONS: Zirconia and PEEK could be considered both good materials, but several investigations are needed to use these materials as an alternative to metals for fixed partial dentures.

OBJECTIVE: Ascorbyl palmitate is a fat-soluble ester of vitamin C and is used as an antioxidant food additive. While literature reports that ascorbyl palmitate can prevent exacerbation of pain and improve the quality of life of patients suffering from pain, this is not yet supported by clinical trial data. Our study aimed to investigate the effectiveness of ascorbyl palmitate in managing trigeminal neuralgia. PATIENTS AND METHODS: This study was carried out in a single-centre clinical trial in which subjects suffering from trigeminal neuralgia (N=11) were included. All patients were on carbamazepine when first included and, after washout period, received Ascorbyl palmitate. Eligible patients had the most severe trigeminal neuralgia pain in the oral cavity or pain on touching trigger zones, aged 20 years or older, were capable of proper assessment of the severity of pain and their condition, and had experienced multiple episodes of intraoral pain for at least 3 months with a pain intensity of more than 4 points on the numerical rating scale. The Brief Pain Questionnaire was used to evaluate patient’s quality of life. RESULTS: A total of 11 patients were included with a mean age 55.36±10.67 years (7 males, 4 females). Most patients had compression by the superior cerebellar artery and vascular loops upon magnetic resonance examination. The mean numerical rating scale score for carbamazepine after one month was 7.9±0.56 (95% CI 7.49, 8.30). Similarly, for ascorbyl palmitate was 5.5±1.50 (95% CI 4.42, 6.57) (p<0.001). CONCLUSIONS: Ascorbyl palmitate can be used as an adjunct intervention in managing trigeminal neuralgia pain. According to the results, ascorbyl palmitate prevents frequent exacerbation of pain and improves patient quality of life. [ABSTRACT FROM AUTHOR]
