Abstract
Melatonin is a highly conserved molecule produced in the human pineal gland as a hormone. It is known for its essential biological effects, such as antioxidant activity, circadian rhythm regulator, and immunomodulatory effects. The gut is one of the primary known sources of melatonin. The gut microbiota helps produce melatonin from tryptophan, and melatonin has been shown to have a beneficial effect on gut barrier function and microbial population. Dysbiosis of the intestinal microbiota is associated with bacterial imbalance and decreased beneficial microbial metabolites, including melatonin. In this way, low melatonin levels may be related to several human diseases. Melatonin has shown both preventive and therapeutic effects against various conditions, including neurological diseases such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis. This review was aimed to discuss the role of melatonin in the body, and to describe the possible relationship between gut microbiota and melatonin production, as well as the potential therapeutic effects of melatonin on neurological diseases.

Abstract
BACKGROUND The incidence of thyroid carcinoma has been increasing worldwide and surgery is the primary treatment. Central compartment dissection of the neck is a very delicate procedure given the risks of recurrent laryngeal nerve injury and hypoparathyroidism. METHODS This paper gives a detailed description of this surgical technique in a patient affected by papillary carcinoma of the thyroid gland, supported by highly representative iconographic materials from a tertiary department. RESULTS A stepwise description is provided, along with high-quality pictures and specific tips and tricks. Although neck dissection is a well-codified procedure, the fine details of this surgical technique are not currently available and are still the prerogative of the expert surgeon. CONCLUSION The central neck compartment contains several vulnerable structures; damage to these structures would affect patients' lives, possibly permanently. Anatomical knowledge and standardisation are needed for all surgeons, particularly new surgeons (such as residents) who cannot rely simply on experience.

Abstract
Radiomics focuses on extracting a large number of quantitative imaging features and testing both their correlation with clinical characteristics and their prognostic and predictive values. We propose a radiomic approach using magnetic resonance imaging (MRI) to decode the tumor phenotype and local recurrence in oropharyngeal squamous cell carcinoma (OPSCC). The contrast-enhanced T1-weighted sequences from baseline MRI examinations of OPSCC patients treated between 2008 and 2016 were retrospectively selected. Radiomic features were extracted using the IBEX software, and hiegrarchical clustering was applied to reduce features redundancy. The association of each radiomic feature with tumor grading and stage, HPV status, loco-regional recurrence within 2 years, considered as main endpoints, was assessed by univariate analysis and then corrected for multiple testing. Statistical analysis was performed with SAS/STAT® software. Thirty-two eligible cases were identified. For each patient, 1286 radiomic features were extracted, subsequently grouped into 16 clusters. Higher grading (G3 vs. G1/G2) was associated with lower values of GOH/65Percentile and GOH/85Percentile features (p=0.04 and 0.01, respectively). Positive HPV status was associated with higher values of GOH/10Percentile (p=0.03) and lower values of GOH/90Percentile (p=0.03). Loco-regional recurrence within 2 years was associated with higher values of GLCM3/4-7Correlation (p=0.04) and lower values of GLCM3/2-1InformationMeasureCorr1 (p=0.04). Results lost the statistical significance after correction for multiple testing. T stage was significantly correlated with 9 features, 4 of which (GLCM25/180-4InformationMeasureCorr2, Shape/MeanBreadth, GLCM25/90-1InverseDiffMomentNorm, and GLCM3/6-1InformationMeasureCorr1) retained statistical significance after False Discovery Rate correction. MRI-based radiomics is a feasible and promising approach for the prediction of tumor phenotype and local recurrence in OPSCC. Some radiomic features seem to be correlated with tumor characteristics and oncologic outcome however, larger collaborative studies are warranted in order to increase the statistical power and to obtain robust and validated results.

Abstract
Abstract
A column high-performance liquid chromatography (HPLC) method was developed for the determination of glucosamine in dosage forms. Glucosamine was derivatized by addition of a solution containing orthophthaldialdehyde. The HPLC separation was achieved on a Spherimage 80 ODS2 column (250 4 mm id, 5 μm particle size) using an isocratic mobile phase containing phosphate buffermethanol (90 + 10, v/v, pH 6.50) and methanoltetrahydrofuran (97 + 3, v/v) in proportions of 85 + 15 at a flow rate of 1 mL/min, followed by fluorescence detection. The method was validated for specificity, linearity, accuracy, precision, limit of detection (LOD), and limit of quantitation (LOQ). The detector response for glucosamine HCl was linear over the concentration range of 0.120 μg/mL with a correlation coefficient of 0.9980. The accuracy was between 99.4 and 100.8%. The LOD and the LOQ were 0.009 and 0.027 μg/mL, respectively. The method was applied to determination of glucosamine in solid dosage forms.

Abstract
SUMMARY Head and neck (H&N) tumours are a heterogeneous group of neoplasms with 5-year relative survival ranging from about 25% for the hypopharynx to 60% for the larynx in Europe. To improve survival rates, along with therapeutic improvements, it is important to standardise and optimise care received by patients with H&N tumours across different healthcare providers. To reach this goal, it is necessary to evaluate adherence to standards of received care at a population level. Published guidelines can serve as the basis to develop indicators, which can be computed from administrative health databases, measuring the adherence to specific recommendations at the individual level in unselected H&N cancer patients, identified from a population cancer register. We developed a set of indicators and calculated them in a cohort of 2007-2012 incident cases of H&N tumours in the cancer register of the Milan province (n = 1441 cases). The study cohort was mainly composed of men (77%) and patients older than 50 years (89%). Surgery was the most frequently employed treatment (66%). Ten percent of patients had no recorded treatment. Timing between cyto-histological assessment and first therapy for those having a recorded microscopic verification procedure was ≤ 60 days for 90.4% of patients undergoing surgery, 86.3% of those undergoing radiotherapy, and 90.7% of patients receiving chemotherapy. Eighty-three percent of patients underwent cyto-histological assessment in the 180 days before the first treatment. Evaluation by a pain therapist, opioid therapy or hospitalisation for palliative therapy in the 90 days before death was performed in 51% of patients who eventually died of cancer. This is the first Italian study defining and calculating quality indicators to monitor adherence to standards of care received by H&N cancer patients at a population level.

Abstract
Contamination of food producing animals by veterinary drug residues, particularly quinolones, is an essential issue in food safety that causes increasing concern in consumers. The aim of this study was to investigate the occurrence of enrofloxacin and its main metabolite, ciprofloxacin, in chicken tissue samples slaughtered in Tabriz, Iran. Totally 250 samples including liver, muscle, gizzard, heart, and skin were studied. Dispersive liquid-liquid microextraction technique (DLLME) was used as a simple, high performance, low-cost, and fast sample pre-treatment method followed by a high-performance liquid chromatography with UV detection for quantitative analysis. The residues of enrofloxacin were detected and quantified in 26 liver (52%) and 10 skin (20%) samples and ciprofloxacin residues were detected in 3 skin (6%) samples and accurately determined in 15 liver (30%) samples; however they were not detected in gizzard, heart, and muscle samples. The results showed the accumulation of enrofloxacin and ciprofloxacin residues in chicken liver and skin.

Abstract
Malignant metastases to the thyroid are rare and are even rarer from a colorectal primary. As these metastases are often asymptomatic, they are usually discovered incidentally on imaging performed as follow-up for the primary tumour. In this report, we present a case of metastatic sigmoid adenocarcinoma to the thyroid diagnosed and treated at our institution.

Abstract
BACKGROUND AND OBJECTIVE The purpose of the present study was to compare the bioavailability of a new methyldopa (CAS 555-30-6) tablet formulation with that of a reference formulation in 12 healthy male subjects using a modified HPLC method. METHODS The study was designed as an open label, single-dose, randomized study with a cross-over design. Under fasting conditions, each subject received one 250-mg tablet orally as a single dose of a test or reference formulation on two treatment days. The treatment periods were separated by a one-week washout period. The blood samples were collected at different time points after each administration and determined using a rapid and reliable modified HPLC method. The method used was validated for specificity, accuracy, precision and sensitivity. The pharmacokinetic parameters (Cmax, AUC0-t, AUC0-infinity) were statistically compared by analysis of variance (ANOVA) for test and reference formulations. RESULTS AND DISCUSSION All validation criteria for the developed HPLC method were in acceptable range. The maximum plasma concentration (Cmax) of alpha-methyldopa was 270.3-1864.9 ng/ml for the test and 224.5-1585.6 ng/ml for the reference formulation. The mean AUC0-infinity of alpha-methyldopa was 2002.1-10614.8 and 2076.8- 9056.3 ng x h/ml for the test and reference formulation, respectively. The calculated 90% confidence intervals for the mean test/reference ratios of mentioned parameters were 92.48-115.94, and 88.82-101.13 which are in the bioequivalence range. The statistical tests did not show any statistical differences between formulations suggesting that methyldopa tablet of test and reference can be considered as bioequivalent preparations. CONCLUSION A rapid and reliable HPLC method with fluorescence detector was developed to analyze alpha-methyldopa in human plasma. Based on the obtained results the test formulation of alpha-methyldopa is bioequivalent to the reference formulation.

Abstract
The aim of curative surgical oncology is to remove the primary tumour with a wide margin of normal tissue. What constitutes a sufficiently wide margin particularly in oral cancer is fundamentally unclear. The currently accepted standard is to remove the primary lesion with a 1.5-2 cm circumferential macroscopic margin. In the last ten years, anatomical considerations in the approach to primary, advanced and untreated tumours of the tongue led us to develop and improve a new surgical approach to their demolition and reconstruction. From July 1999 to July 2009, at the European Institute of Oncology in Milano, Italy, 155 patients were treated, while defining and refining the concept of compartmental tongue surgery (CTS) and its main components: 1) anatomical approach to the disease that requires removal of the primary lesion and all of the potential pathways of progression--muscular, lymphatic and vascular; 2) identification of a distinct territory at risk of metastatic representation of the disease: the parenchymal structures between the primary tumour and the cervical lymphatic chain that include the muscular (mylohyoid), neuro-vascular (lingual nerve and vein) and glandular (sublingual and submandibular) tissues; 3) preparation for a rational reconstruction in consideration of a functional defect resulting from this anatomical demolition.

Abstract
Prophylactic central neck dissection in papillary thyroid cancer is controversial. In this retrospective cohort study, the aim was to assess possible advantages of prophylactic central neck dissection with total thyroidectomy in cN0 papillary thyroid cancer. A total of 244 consecutive patients with papillary thyroid cancer, without clinical and ultrasound nodal metastases (cN0), were evaluated out of 1373 patients operated for a thyroid disease at the Istituto Europeo di Oncologia, Milan, Italy from 1994 to 2006. Of these 244 patients, 126 (Group A) underwent thyroidectomy with central neck dissection, while 118 (Group B) underwent thyroidectomy alone. Demographic, clinical and pathological features were analysed. Overall recurrence rate was 6.3% (8/126) in Group A and 7.7% (9/118) in Group B, with a mean follow-up of 47 (Group A) and 64 (Group B) months. In Group A patients, 47% were pN1a and all patients with recurrence had nodal involvement (p = 0.002). Survival rate did not differ in the two groups. Nine patients were lost to follow-up. Group A patients were older and their tumours were larger in size; according to the pT distribution, a higher extra-capsular invasion rate was observed. The two groups were equivalent as far as concerns histological high risk variants and multifocality. Nodal metastases correlated with stage: pT1-2 vs. pT3-T4a, p = 0.0036. A lower risk of nodal metastases was related to thyroiditis (p = 0.0034). In conclusion, central neck metastases were predictive of recurrence without influencing prognosis. From data obtained, possible greatest efficacy of central neck dissection in pT3-4 papillary thyroid cancer without thyroiditis is suggested.

Abstract
Chitin was prepared from Persian Gulf shrimp (Metapenaeus monoceros), and then, the obtained chitin was hydrolyzed by hydrochloric acid solutions. The production yield of glucosamine hydrochloride from chitin was optimized, and the effect of three factors (acid concentration, acid to chitin ratio, and reaction time) was investigated. A Box-Behnken design by Minitab software created 12 reactions with different conditions. Each reaction was performed in two replicates. Response surface methodology was used for predicting the glucosamine preparation. The optimum conditions for glucosamine hydrochloride preparation were 30 and 37% hydrochloric acid, 9:1 (v/w) acid solution to solid ratio, and 4 h of reaction time. Time ratio and time acid concentrations were the effective factors on the yield.

Abstract
A column high-performance liquid chromatography (HPLC) method was developed for the determination of glucosamine in dosage forms. Glucosamine was derivatized by addition of a solution containing orthophthaldialdehyde. The HPLC separation was achieved on a Spherimage 80 ODS2 column (250 x 4 mm id, 5 microm particle size) using an isocratic mobile phase containing phosphate buffer-methanol (90 + 10, v/v, pH 6.50) and methanol-tetrahydrofuran (97 + 3, v/v) in proportions of 85 + 15 at a flow rate of 1 mL/min, followed by fluorescence detection. The method was validated for specificity, linearity, accuracy, precision, limit of detection (LOD), and limit of quantitation (LOQ). The detector response for glucosamine HCI was linear over the concentration range of 0.1-20 microg/mL with a correlation coefficient of 0.9980. The accuracy was between 99.4 and 100.8%. The LOD and the LOQ were 0.009 and 0.027 microg/mL, respectively. The method was applied to determination of glucosamine in solid dosage forms.

Abstract
Squamous cell carcinoma of the oral cavity represents about 2% of all malignant neoplasms and 47% of those developing in the head and neck area. The tongue is the most common site involved, and this incidence is increasing mainly in young people, possibly related to human papilloma virus infections. Prognosis depends on the stage: the 5-year survival rate of tongue squamous cell carcinoma, whatever the T stage, is 73% in pN0 cases, 40% in patients with positive nodes without extracapsular spread (pNl ECS-), and 29% when nodes are metastatic with extracapsular spread (pNl ECS+: p > or = 0.0001). Nodal micrometastases (cN0 pN1) are found in up to 50% of cN0 tongue squamous cell carcinoma patients operated on the neck. At present, no clinical, imaging staging modalities or biological markers are available to diagnose nodal micrometastases. The sentinel node biopsy has been tested since 1996 in order to find a solution to this problem. The sentinel node is the first node reached by the lymphatic stream, assuming an orderly and sequential drainage from the tumour site, and should be predictive of the nodal stage. According to the literature, sentinel node biopsy is a reliable technique in selected cN0 cases, but the procedure is still experimental and should not be performed outside validation trials. Successful application of sentinel node biopsy in the head and neck region requires surgical experience and specific technical devices, including pre-operative lymphoscintigraphy and intra-operative gamma-probe. Moreover, dynamic lymphoscintigraphy seems to be able to show the lymphatic stream from the primary tumour and could allow a selective neck dissection to be tailored thus reducing the related morbidity.

Abstract
BACKGROUND Detecting metastases to the cervical lymph nodes is the main problem in the management of squamous cell carcinoma of the tongue. We investigated the ability of sentinel node (SN) biopsy to predict neck status in 11 patients with lateral T1-T2, N0, and M0 squamous cell carcinoma of the tongue who underwent ipsilateral neck dissection 30 to 40 days after primary surgery. METHODS In 5 patients, technetium 99m-labeled particles were injected close to the operation scar on the day before neck dissection, and the labeled neck nodes were revealed by lymphoscintigraphy. The next 6 patients underwent lymphoscintigraphy both before surgery and before neck dissection. During neck dissection, the ipsilateral SNs were identified by using a hand-held probe and removed separately. RESULTS Three patients (27%) had metastatic neck nodes. In all cases, labeled nodes were revealed by scintigraphy. Ipsilateral SNs were removed from 8 patients and correctly predicted the state of the neck (6 negatives and 2 positives). Lymphoscintigraphy before and after surgery revealed that drainage was modified after surgery in 5 of 6 patients; the pre-surgery drainage pattern varied markedly among the 5 pN0 patients. CONCLUSIONS The technique allows easy and safe identification of SNs and shows promise in guiding selective neck dissection. Surgery on the primary tumor often modifies lymphatic drainage, so that SN biopsy may only be useful if the primary operation and neck dissection are performed at the same time.

Abstract
The ability to reliably predict cancer outcome could tailor therapy to the aggressiveness of the tumour to achieve the best results in terms of loco-regional control, overall survival and quality of life. Retrospective and prospective clinical trials involving large series of patients have validated some predictive clinical and pathological factors, whereas the utility of many other prognostic factors has not been established. This has led to some confusion in clinical practice. In order to clarify the significance, role and cost of these prognostic factors we carried out a Medline search of all papers published between 1993 and 1998 concerning the reliability and cost of markers with prognostic significance, in head and neck squamous cell carcinoma, and assessed the results according to a number of criteria relating to reliability and cost. Regarding reliability we classified prognostic factors into: (1) those with a proven significance based on the fact that they were unanimously reported as having an independent statistical correlation with outcome and prognosis; and (2) those for which results were not unanimous, and which significance is still controversial. Cost analysis showed a substantial difference between validated tests which are of low cost and experimental tests which are expensive. Based on these data regarding both the reliability and cost of each prognostic factor, we propose guidelines for their use in clinical practice in the year 2000.
