Abstract
Cadmium (Cd) is a transition heavy metal that is able to accumulate in the central nervous system and may induce cell death through reactive oxygen species (ROS)-mediated mechanisms and inactivating the antioxidant processes, becoming an important risk factor for neurodegenerative diseases. The antioxidant effects of cannabinoid receptor modulation have been extensively described, and, in particular, β-Caryophyllene (BCP), a plant-derived cannabinoid 2 receptor (CB2R) agonist, not only showed significant antioxidant properties but also anti-inflammatory, analgesic, and neuroprotective effects. Therefore, the aim of the present study was to evaluate BCP effects in a model of Cd-induced toxicity in the neuroblastoma SH-SY5Y cell line used to reproduce Cd intoxication in humans. SH-SY5Y cells were pre-treated with BCP (25, 50, and 100 μM) for 24 h. The day after, cells were challenged with cadmium chloride (CdCl2; 10 μM) for 24 h to induce neuronal toxicity. CdCl2 increased ROS accumulation, and BCP treatment significantly reduced ROS production at concentrations of 50 and 100 μM. In addition, CdCl2 significantly decreased the protein level of nuclear factor erythroid 2-related factor 2 (Nrf2) compared to unstimulated cells; the treatment with BCP at a concentration of 50 μM markedly increased Nrf2 expression, thus confirming the BCP anti-oxidant effect. Moreover, BCP treatment preserved cells from death, regulated the apoptosis pathway, and showed a significant anti-inflammatory effect, thus reducing the pro-inflammatory cytokines increased by the CdCl2 challenge. The results indicated that BCP preserved neuronal damage induced by Cd and might represent a future candidate for protection in neurotoxic conditions.

Abstract
Many natural substances commonly found in healthy diets have been studied for their potential to reduce male infertility associated with varicocele. A positive role of selenium (Se) or lycopene alone was demonstrated in experimental varicocele, while no data are available on their association. One group of male Sprague-Dawley rats was sham operated and daily treated with Se (3 mg/kg, i.p.), lycopene (1 mg/kg, i.p.), or their association. A second group underwent surgery to induce varicocele. Sham and half of the varicocele animals were sacrificed after twenty-eight days, while the residual animals were treated for one more month and then sacrificed. In varicocele animals, testosterone levels and testes weight were reduced, Hypoxia Inducible Factor-1α (HIF-1α) expression was absent in the tubules and increased in Leydig cells, caspare-3 was increased, seminiferous epithelium showed evident structural changes, and many apoptotic germ cells were demonstrated with TUNEL assay. The treatment with lycopene or Se alone significantly increased testis weight and testosterone levels, reduced apoptosis and caspase-3 expression, improved the tubular organization, decreased HIF-1α positivity of Leydig cells, and restored its tubular positivity. Lycopene or Se association showed a better influence on all biochemical and morphological parameters. Therefore, the nutraceutical association of lycopene plus Se might be considered a possible therapeutic tool, together with surgery, in the treatment of male infertility. However, long-term experimental and clinical studies are necessary to evaluate sperm quantity and quality.

Abstract
Introduction Central precocious puberty (CPP) results from premature activation of hypothalamic-pituitary-gonadal axis, with the consequent increase of gonadotropin-releasing hormone (GnRH); GnRH agonists (GnRHa) represent the gold-standard therapy in children with CPP although their use might be responsible for pituitary GnRH receptors down-regulation, that in turn suppresses luteinizing hormone (LH) and follicle stimulating hormone (FSH) and blocks of gonadal sex hormones release. The most prescribed GnRHa in the clinical practice are leuprolide and triptorelin, whose use is generally safe and well tolerated; however, mild menopausal-like side effects could appear. The aim of the present study was to investigate and compare the efficacy and tolerability profile of leuprolide and triptorelin in CPP patients. Methods 110 girls affected by CPP were enrolled in this retrospective study, carried out from 2018 to 2020. The enrolled patients received leuprolide (n = 48) or triptorelin (n = 62). Efficacy was investigated by the means of clinical parameters and radiological changes and side effects were also recorded to evaluate the possible relationship between the two GnRHa treatments and side effects appearance. Results At baseline triptorelin patients had significantly higher LH and LH peak levels than leuprolide patients, whereas no significant difference in other patient characteristics was observed between the two groups. The leuprolide treatment lasted 971 days [790-1,171 days] while the duration of triptorelin administration was 792 days [760-1,003 days] (p < 0.001). Overall 46 (41.8%) of the studied patients reported mild menopausal-like symptoms: among these 27 were treated with triptorelin and 19 with leuprolide (p = 0.558). Patients treated with triptorelin, or leuprolide showed headache (27.4% vs. 16.7%), mood swings (12.9% vs. 16.7%), increased appetite (12.9% vs. 18.8%) and nausea (1.6% vs. 10.4%) respectively. Moreover, the onset of side effects appearance related to GnRHa therapy significantly reduces with the increase of the initial bone age (p = 0.038). Conclusion Leuprolide and triptorelin treatment appear to be effective and safe without significant difference between the two drugs in term of efficacy and tolerability, making both good options for treating CPP.

Abstract
Chronic glucocorticoid (GC) therapy is the most common cause of iatrogenic osteoporosis and represents an important risk factor for osteoporosis and bone fractures. New therapeutic approaches are required in order to treat osteoporosis and reduce the side effects related to the use of anti-osteoporotic drugs. In this context, previous studies reported the efficacy of some isoflavones and carotenoids, such as lycopene and genistein, on the reduction of the risk of fracture related to osteoporosis. The aim of this study was to investigate the effects of a combined oral treatment, consisting of genistein and lycopene, in an experimental model of glucocorticoid-induced osteoporosis (GIO). GIO was induced by subcutaneous injection of methylprednisolone (MP, 30 mg/kg) for 60 days, whereas the control group (Sham) received saline solution only. Following induction, MP animals randomly were assigned to receive alendronate, genistein, lycopene, or the association of genistein and lycopene or saline solution for additional 60 days together with MP. Femurs obtained from the Sham group were used for osteoblasts extraction; they were then incubated with dexamethasone (DEX) for 24 h to be then treated with lycopene or genistein or the association of lycopene and genistein for an additional 24 h. Treatments with lycopene and genistein restored the impaired mineralization of cells observed following DEX treatment and stimulated osteoblast differentiation by increasing the depressed expression of bALP and RUNX2 (p < 0.0001). Wnt5a, β-catenin, and Nrf-2 expression were significantly increased following genistein and lycopene treatment (p < 0.0001), thus confirming their antioxidant activity as well as their ability in stimulating osteoblast function, mostly when genistein and lycopene were used in association. The combined treatment of genistein and lycopene improved the bone damage induced by glucocorticoids and significantly restored the normal architecture of bones as well as adequate interconnectivity of bone trabeculae, thus increasing bone mineral density parameters. The obtained data demonstrated that genistein and lycopene but in particular their association might prevent GC’s adverse effects, thus stimulating bone formation and reducing bone resorption, improving bone structure and microarchitecture, through different molecular pathways, such as the Wnt/β-catenin and the Nrf-2 signaling.

Abstract
Background: Antibiotics are prescribed for children both in hospital and community settings, particularly at preschool age. Italy shows a high rate of inappropriate antibiotic prescriptions which may represent a serious problem in the hospital scenario. Thus, the aim of this study was to investigate appropriateness of antibiotic prescribing in the context of different paediatric subspecialties in a hospital setting. Methods: Antibiotics prescribing was retrospectively analysed in paediatric patients (0–18 years) admitted in the emergency paediatrics, general paediatrics, paediatric nephrology and rheumatology units between January and December 2019. Patients were stratified by age in neonates, infants, toddlers, children and adolescents. Assessments were conducted by trained local assessors and appropriateness was classified as appropriate, inappropriate and not assessable. Results: Empirical antibiotics were mainly prescribed following a diagnosis of respiratory, gastrointestinal and/or urinary infection. A total of 825 antibiotic prescriptions were recorded in the three subspecialties; 462 antibiotic prescriptions (56%) out of 825 were assessed as inappropriate and 55 prescriptions (6.7%) were not assessable. Inappropriateness considerably varied within subspecialties: the risk of inappropriate antibiotic prescribing was higher in emergency paediatrics and general paediatric than in children, according to age. Ceftriaxone and clarithromycin were the most inappropriate prescribed antibiotics in the emergency paediatrics whereas amoxicillin/clavulanic acid represented the most inappropriate antibiotic prescribed in general paediatrics. Conclusion: The present data may be useful in order to reduce inappropriate antibiotic prescribing in the paediatric setting; antibiotic stewardship and clinical improvement programs in hospital paediatric care are strongly recommended.

Abstract
Oral surgery has undergone dramatic developments in recent years due to the use of biomaterials. The aim of the present review is to provide a general overview of the current biomaterials used in oral surgery and to comprehensively outline their impact on post-operative wound healing. A search in Medline was performed, including hand searching. Combinations of searching terms and several criteria were applied for study identification, selection, and inclusion. The literature was searched for reviews published up to July 2020. Reviews evaluating the clinical and histological effects of biomaterials on post-operative wound healing in oral surgical procedures were included. Review selection was performed by two independent reviewers. Disagreements were resolved by a third reviewer, and 41 reviews were included in the final selection. The selected papers covered a wide range of biomaterials such as stem cells, bone grafts, and growth factors. Bioengineering and biomaterials development represent one of the most promising perspectives for the future of oral surgery. In particular, stem cells and growth factors are polarizing the focus of this ever-evolving field, continuously improving standard surgical techniques, and granting access to new approaches.

Abstract
BACKGROUND A potential approach to the treatment of morbid obesity is reduction of gastric emptying to achieve satiety. Botulinum toxin A (Btx-A) is a long-acting inhibitor of acetylcholine-mediated peristalsis, which is mainly responsible for gastric motility. AIM To investigate whether botulinum toxin A, injected in the antrum of obese patients, delays gastric emptying. METHODS In a double_blind study, 18 healthy obese subjects (body mass index >30) were randomized into three groups (BTX133, BTX200 and Saline); they received Btx-A133U, Btx-A200U, or saline under endoscopic control. Gastric emptying was tested by scintigraphy before and 10 days after treatment. Body weight variations and appetite sensation were recorded after 5 weeks. RESULTS Fourteen patients completed the study. The botulinum toxin A-treated groups showed weight reduction, which was not statistically significant. The effects on gastric emptying were variable. Most of the botulinum toxin A treated patients reported a reduced appetite. CONCLUSION This pilot clinical trial suggests potential activity of botulinum toxin A for the manipulation of appetite.

Abstract
BACKGROUND/AIMS To study the tolerability of propionyl-L-carnitine administered as rectal irrigation and its efficacy in improving the clinical picture of distal ulcerative colitis. METHODOLOGY Ten male subjects (aged 18 to 55 years, with a body mass index ranging from 21 to 25 Kg/m2) with distal ulcerative colitis were treated with propionyl-L-carnitine enemas (6 g in 200 mL physiological solution) twice a day over 120 minutes each. All subjects had a disease activity index from 0 to 1. A clinical, laboratory, endoscopy and biopsy evaluation was performed at baseline and 14 days after treatment. Serum tumor necrosis factor-alpha and interleukin-2 concentration was measured. RESULTS No side effects were reported by the entire patient population and the clinical conditions remained constant throughout the study period. The disease activity index improved significantly between the beginning and the end of the study in 80% of the patients. Histologic features (mucosal erosion, distortion of crypt architecture, inflammation and lamina propria gap) significantly improved in all treated patients. Serum interleukin-2 levels did not change significantly after propionyl-L-carnitine treatment (respectively: 14.7 +/- 15.8 before vs. 9.9 +/- 13.2 pg/mL), while tumor necrosis factor-alpha levels were undetectable both before and after propionyl-L-carnitine administration. CONCLUSIONS The topical treatment with a new formulation containing propionyl-L-carnitine seems to be safe and effective in improving the histologic features in patients with inactive or mild ulcerative colitis, as an alternative to conventional therapy.

Abstract
The liver has a pivotal role in drug metabolism and hepatic drug reactions are frequent events, accounting for 5% of cases of jaundice or acute hepatitis in the community. The importance of hepatic drug reactions lies not only in their frequency, but also in the great number of molecules that can cause this type of lesions and in their variable gravity. This review will show the main factors implicated in drug metabolism which can explain the different susceptibility in developing hepatic drug reaction, the possibility that it may manifest as a wide spectrum of clinical syndromes or that a single agent may cause more than one lesion (a relevant problem not only for the clinician, but also for the pathologist).

Abstract
One of the main goals of weight reduction in morbidly obese subjects is its benefit on coronary heart disease (CHD) risk. A cross-sectional study was designed to randomly assign 79 morbidly obese subjects (27 men and 52 women; age: 30-45 years) either to a diet protocol (20 kcal per kg fat-free mass (FFM); 55% carbohydrates, 30% fat, and 15% proteins) or to malabsorptive surgery (biliopancreatic diversion). Fatness parameters, measured by dual-energy X-ray absorptiometry, lipid profile, insulin, leptin, sex steroid hormones and sex hormone-binding globulin (SHBG) levels were compared at baseline and 1 year after the beginning of the study. The data showed that plasma SHBG levels, but not testosterone levels, correlated negatively to fasting insulin levels and positively to HDL-cholesterol in both men and women. Total leptin levels were significantly lower (P<0.0001) in post-BPD subjects of both sexes compared to dietary treated obese subjects. The logarithm of plasma leptin correlated significantly and positively with insulin but negatively with SHBG.A step-down regression analysis showed that FFM and SHBG, but not insulin levels, were the most powerful independent variables for predicting HDL-cholesterol levels in morbidly obese patients. The negative relationship between SHBG levels and CHD risk appears to be mediated by a concomitant variation in body fatness. Finally, in obese patients, SHBG levels seem to be an indicator of total adiposity rather than an index of an altered insulin/glucose homeostasis.

Abstract
Inflammatory bowel diseases (IBD) are often characterized by impairment of nutritional status. Crohn's disease (CD) patients, especially in the active phase of disease, show a reduced body weight, due to the reduction of lipid stores, in spite of lean mass depletion. Fat mass reduction has been correlated to an increased utilization of lipids as fuel substrate. The alterations of nutritional status are able, in turn, to influence, as independent factors, the disease course and patient prognosis. A disease's treatment based only on pharmacologic therapy, especially on corticosteroid use in the active phases, often does not take into account the relevant need for preserving a normal nutritional status. In this connection, enteral nutrition has been shown to be able to improve nutritional status and induce and maintain remission. We present some of the possible mechanisms of efficacy of enteral feeding and some rules to attempt to treat patients with IBD, especially those with Crohn's disease.

Abstract
One of the major complications found in patients affected by malignancy of the gastrointestinal tract is represented by an alteration of nutritional status, up to real cachexia. The factors responsible for the severe nutritional deficiencies are: metabolic alterations, which involve carbohydrate, lipid and protein metabolism; the reduced availability of nutritional substrates, due to neoplastic growth that, by expanding locally or destroying the affected organ, determines alterations of deglutition, digestion and food absorption; the effects of surgical therapy, radiotherapy and chemotherapy, which are able to cause temporary or permanent nutritional deficiencies; the effects of immunological mediators, and above all of tumor necrosis factor-alpha (TNF-alpha). In fact, TNF-alpha is considered the main mediator of cancer cachexia as it is responsible for different metabolic alterations, both directly and by the activation of other mediators, such as lipid mobilizing factor (LMF) and protein mobilizing factor (PMF). In addition, a negative energy balance in cancer patients could occur as a consequence of increased energy requirements. In this connection, patients with different neoplasia localisation, show high or within the normal range energy expenditure values. These data indicate that the increase in energy metabolism is not likely to represent the main determining factor in neoplastic cachexia. In conclusion, since patients affected by malignancy of the gastrointestinal tract showed a reduction in body weight, fat and fat-free mass, accurate evaluation of nutritional status should be useful in the management and follow-up of these patients.

Abstract
An impairment of nutritional status up to real malnutrition can frequently be associated to gastrointestinal diseases. The diseases of the gastrointestinal tract can be divided into five groups: those hampering the nutrient physiological transit (especially neoplastic diseases); those affecting the intestinal mucosa (such as chronic inflammatory bowel disease); those determining intraluminal maldigestion; the hepato-biliary diseases and finally, the diseases of the pancreas. In order to correctly evaluate the nutritional status of an individual, besides the determination of the common biochemical parameters, body composition by direct and indirect techniques and energy metabolism by indirect calorimetry should be measured. Patients affected by Crohn's disease showed a lower fat mass content along with higher lipid oxidation compared to patients affected by ulcerative colitis. Patients with coeliac disease at diagnosis had a reduction in both fat and fat-free mass content along with an increased utilisation of carbohydrates as fuel substrate. There are many factors potentially leading to severe malnutrition in pancreatic diseases, especially in the acute form. Due to the primary role played by the liver in the metabolism of energy substrates, an impaired nutritional status might be commonly found in cirrhotic patients. In this connection, our group reported an increased energy expenditure and lipid oxidation, and an insulin-resistant state in compensated liver cirrhotic patients. These alterations seemed to precede and probably to lead to liver-disease-related malnutrition.

Abstract
PURPOSE To describe an unusual presentation of posterior scleritis in a healthy young patient. METHOD We reviewed the medical record of 21-year-old man for clinical presentation, course, and ancillary studies. RESULTS The healthy patient had a painless, bilateral posterior scleritis that presented with a combination of circumscribed fundus masses and exudative macular detachment. On fluorescein angiography, different hyper-fluorescent patterns characterized the two manifestations of posterior scleritis. An ultrasound confirmed the scleral thickening. Fundoscopic abnormalities resolved with oral prednisone. CONCLUSION Pain is not always present in this disease. A combination of exudative macular detachment and circumscribed fundus masses can be a form of presentation in posterior scleritis.
