Abstract
Excited-state spectroscopy from the first experiment at the Facility for Rare Isotope Beams (FRIB) is reported. A 24(2)-μs isomer was observed with the FRIB Decay Station initiator (FDSi) through a cascade of 224- and 401-keV γ rays in coincidence with ^{32}Na nuclei. This is the only known microsecond isomer (1 μs≤T_{1/2}<1 ms) in the region. This nucleus is at the heart of the N=20 island of shape inversion and is at the crossroads of the spherical shell-model, deformed shell-model, and ab initio theories. It can be represented as the coupling of a proton hole and neutron particle to ^{32}Mg, ^{32}Mg+π^{-1}+ν^{+1}. This odd-odd coupling and isomer formation provides a sensitive measure of the underlying shape degrees of freedom of ^{32}Mg, where the onset of spherical-to-deformed shape inversion begins with a low-lying deformed 2^{+} state at 885 keV and a low-lying shape-coexisting 0_{2}^{+} state at 1058 keV. We suggest two possible explanations for the 625-keV isomer in ^{32}Na: a 6^{-} spherical shape isomer that decays by E2 or a 0^{+} deformed spin isomer that decays by M2. The present results and calculations are most consistent with the latter, indicating that the low-lying states are dominated by deformation.

Abstract
A selective and sensitive liquid chromatography-tandem mass spectrometry method was developed and validated for accurate determination of CHF6550 and its main metabolite in rat plasma and lung homogenate samples. All biological samples were prepared by simple protein precipitation method using deuterated internal standards. The analytes were separated on a HSS T3 analytical column with 3.2 min run time at flow rate of 0.5 mL/min. The detection was performed on a triple-quadrupole tandem mass spectrometer equipped with positive-ion electrospray ionization by selected-reaction monitoring of the transitions at m/z 735.3 → 98.0 for CHF6550 and m/z 638.3 → 319.2 and 638.3 → 376.2 for CHF6671. The calibration curves for plasma samples were linear between 50 and 50000 pg/mL for both analytes. The calibration curves for lung homogenate samples were linear within 0.1-100 ng/mL for CHF6550 and 0.3-300 ng/mL for CHF6671. The method was successfully applied to a 4-week toxicity study.

Abstract
New half-lives for exotic isotopes approaching the neutron drip-line in the vicinity of N∼28 for Z=12-15 were measured at the Facility for Rare Isotope Beams (FRIB) with the FRIB decay station initiator. The first experimental results are compared to the latest quasiparticle random phase approximation and shell-model calculations. Overall, the measured half-lives are consistent with the available theoretical descriptions and suggest a well-developed region of deformation below ^{48}Ca in the N=28 isotones. The erosion of the Z=14 subshell closure in Si is experimentally confirmed at N=28, and a reduction in the ^{38}Mg half-life is observed as compared with its isotopic neighbors, which does not seem to be predicted well based on the decay energy and deformation trends. This highlights the need for both additional data in this very exotic region, and for more advanced theoretical efforts.

Abstract
UNLABELLED Available reports dealing with acute nonspecific mesenteric lymphadenitis do not address the total duration of symptoms. However, it is commonly assumed a time for recovery ≤ 4 weeks. The purpose of this report was to investigate the course of acute nonspecific mesenteric lymphadenitis in childhood. A review was made of the patients aged ≤ 16 years in whom the diagnosis of acute nonspecific mesenteric lymphadenitis was established between 2011 and 2015 at the Pediatric Emergency Unit. The records of the Pediatric Emergency Unit, those of the referring family doctors, and the results of a structured telephone interview with each family were used. Forty-four patients (25 girls and 19 boys) aged 2.5 to 16, median 8.2, years were included. A bimodal distribution in duration of symptoms was observed: symptoms persisted for ≤ 2 weeks in 22 patients and 3 to 10 weeks in 22. Clinical and laboratory characteristics were similar in children with symptoms persisting for 2 weeks or less 28 and in those with symptoms persisting for 3-10 weeks. CONCLUSION In patients affected with acute nonspecific mesenteric lymphadenitis, it is advantageous to think of the time span for recovery in terms of ≥ 4 weeks. What is Known: • Mesenteric adenitis is a self-limiting inflammatory condition with well-characterized clinical presentation and imaging features. • A total duration of symptoms of ≤ 4 weeks is usually hypothesized. What is New: • Symptoms persist for 3 to 10 weeks in half of the patients. • At presentation, clinical and laboratory characteristics are similar in children with symptoms persisting for 2 weeks or less and in those with 45 symptoms persisting for 3-10 weeks.

Abstract
An 18-month-old male entire Bloodhound dog was presented with a six-week history of progressive inspiratory dyspnoea, stridor, dysphonia and exercise intolerance. CT scan performed elsewhere had revealed the presence of an unencapsulated nodular mass (3x1x5 cm) dorsal to the larynx and first tracheal rings. Laryngoscopy demonstrated the presence of bilateral laryngeal paralysis and distorted laryngeal architecture suggestive of extraluminal compression. Histopathology results of incisional biopsies from the mass were suggestive of a benign non-neoplastic muscular lesion. Surgery was performed to manage laryngeal paralysis and attempt mass excision. A second histopathology examination confirmed an inflammatory and dysplastic lesion suggestive of a pseudotumour. All clinical signs resolved after surgery and at the 13 months follow-up the dog remains asymptomatic. To the authors’ knowledge, this is the first report of a case of laryngeal paralysis caused by a muscle pseudotumour in a young dog.

Abstract
In recent years, low vitamin D status has been proposed as a putative risk factor for allergic diseases. A growing body of literature reports low vitamin D levels in atopic patients and supports an association between vitamin D deficiency and risk of adverse asthma and allergies outcomes. Therefore, it has been speculated that vitamin D supplementation may either prevent or reduce the risk of allergic diseases. Birth cohort studies addressing the role of vitamin D intake during pregnancy have shown conflicting results regarding allergy outcomes in offspring. Currently, only a few studies have tried to supplement vitamin D in asthmatic patients, often as an add-on therapy to standard asthma controller medications, and results are not all consistent. There is emerging data to show that vitamin D can enhance the antiinflammatory effects of glucocorticoids and potentially be used as adjuvant therapy in steroid-resistant asthma. Recent in vivo data suggest that vitamin D supplementation may also reduce the severity of atopic dermatitis. This review examines the existing relevant literature focusing on vitamin D supplementation in the treatment of allergic diseases.

Abstract
Antibacterial drugs are used worldwide for the control of American and, less often, European foulbrood. Their administration is mostly uncontrolled and applied without approved protocols and instructions for use as well as precautionary recommendations. Consequently, this practice is responsible for the contamination of beehive products and contributes to the problem of food safety. According to this situation, 4672 analyses were carried out on 5303 honeys collected from 2001 to 2007. These samples were investigated for antibacterial residues of tetracyclines, sulphonamides, streptomycin, chloramphenicol and tylosin. Honeys were classified according to their origin: imported honey and honey from the Italian market. In the last group (only for samples collected from 2001 to 2004), another type of honey was distinguished: that of local honey. A total of 6.3% of all samples were positive for the antibacterial drugs analysed; in particular, 6.8% of imported honeys and 6.1% of honeys on the Italian market. Only 1.7% of local honey had antibacterial residues. These results are indicative of a rather frequent presence of antibacterial drug residues in both Italian and imported honeys. Furthermore, the data showed that among the active substances analysed, sulphonamides are the most used antibacterial substance followed by tetracyclines, streptomycin, tylosin, and chloramphenicol. Finally, a continuous monitoring programme is needed, accompanied by an education programme to beekeepers on proper hive management.

Abstract
Atopic dermatitis (AD) is a common skin disease characterized by a complex pathogenesis not completely understood despite numerous studies to date. The clinical patterns result from interactions between genetic disorders determining abnormalities in the epidermis differentiation complex, modification of the cutaneous barrier, and dysfunction of immune responses. Several studies have shown that an alteration of the skin barrier combined with immune dysfunction is important for the onset, maintenance, and risk of exacerbations of the disease. In recent years, new aspects regarding the pathogenesis of the disease, such as the effects of vitamin D (VD) on immunity at the skin level and the role of certain microorganisms (particularly Staphylococcus and Malassezia species) on eczema exacerbations, have been evaluated. This article provides an overview of the evidences supporting the link between VD (deficiency) and microorganisms (skin colonization/sensitization) in AD pathogenesis, based on comprehensive review of the literature. By considering different aspects of disease, it might be possible to improve our understanding, particularly in those patients refractory to conventional treatments. An electronic research strategy was used to search in Medline Pub-Med Library using as research words AD, exacerbation, VD, Staphylococcus aureus (SA), and Malassezia. The results were downloaded and analyzed for systematic review. Few studies actually consider the relationship between VD deficiency (VDD), AD, and SA and Malassezia, but many suggest a correlation between these factors. VDs play a major role against microorganisms in the development of AD and should be considered when treating patients.

Abstract
A sensitive and specific method based on high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS), for the simultaneous determination of lincomycin and five macrolide antibiotics in honey, was developed and validated. The analytes were extracted with Tris buffer 0.1 M, pH 10.5, and cleaned-up by a single solid-phase extraction step on OASIS HLB column. The chromatographic separation of analytes was performed on a Synergi Hydro-RP reversed-phase column using a gradient programme of aqueous 0.01 M ammonium acetate, pH 3.5, and acetonitrile as the mobile phase, at a flow rate 0.25 ml min-1. The detection of analytes was achieved by positive ionization electrospray in multiple reaction-monitoring mode. Two characteristic transitions were monitored for each substance. The following analytical parameters were validated according to the guidelines laid down by European Commission Decision 2002/657/EC (European Commission 2002): linearity, specificity, decision limit (CCalpha), detection capability (CCbeta), repeatability, within-laboratory reproducibility, recovery and ruggedness.

Abstract
A 9-year-old, intact male Doberman Pinscher was examined because of anorexia and weakness. Results of a CBC showed severe, microcytic, hypochromic anemia with mild eosinophilia (2944 cells/microL, reference interval 100-1250/microL) and thrombocytosis. Hypoferremia, hypoferritinemia, and a positive fecal occult blood test supported a diagnosis of iron deficiency anemia secondary to chronic intestinal hemorrhage. Abdominal ultrasound evaluation showed a thickened small intestinal loop, of which representative specimens were obtained during exploratory laparotomy. Histologically, the intestinal wall was infiltrated by a neoplastic population of large, round, lymphoid cells with vesicular chromatin, 1 or more prominent nucleoli, and a high number of mitotic figures. The cells were closely admixed with mature eosinophils, but were negative for metachromatic granules with toluidine blue. Immunohistochemically, tumor cells were positive for CD3, and negative for CD21, Pan B, and CD79a. A diagnosis of intestinal T-cell lymphoma was made. Chemotherapy was begun, with 30 mg/m;2 of doxorubicin administered intravenously every 3 weeks. Eosinophil concentration was 880/microL 2 weeks after surgery (on day 15 after presentation) but increased markedly to 62,914/microL on day 30, 62,400/microL on day 37, and 39,444/microL on day 58 after presentation. An association between hypereosinophilia and T-cell lymphoma is well established in human patients, in whom production of IL-5 by neoplastic T cells has been demonstrated. Hypereosinophilia has been reported only rarely with intestinal lymphoma in cats and horses, and with T-cell lymphoma in dogs.

Abstract
Several techniques for castration of cryptorchid cats have been described. In this case report, the use of laparoscopy for castration of a bilateral cryptorchid cat (with testes located in the abdomen) is described. Three trocars were inserted into the abdominal cavity, the testicles were easily identified adjacent to the urinary bladder. Haemostasis of the gubernaculum testis and spermatic cord was achieved with bipolar cauterisation. The testicles were easily removed in approximately 20 min. To the authors' knowledge this is the first report of the use of laparoscopy for the treatment of cryptorchidism in cats.

Abstract
The authors report a rare case of non-familial cherubism with a six-year follow-up. After an analysis of the hereditary transmission of the disease, the authors evaluate the anatomopathological and radiological characteristics and differential diagnosis, and then discuss possible therapies in the light of the latest research. They underline the important role of CT in identifying lesions which may not be diagnosed by simple X-ray with orthopantomography and highlight the importance of taking extreme care to conserve as much dental and bone tissue as possible during surgery.

Abstract
The apical granuloma, the periapical abcess and the radicular cyst are the most frequent between the inflammatory odontogenic lesions of the jaws. These three lesions are caused by the necrosis of the pulp but are very different between each other from an histological point of view and they can correspond to different stages of the same pathological process considering the fact that from a granuloma can arise a periapical abcess or a radicular cyst and from a radicular cyst and abcess can originate. About these three pathological processes we discuss in this article the clinical, radiographical, ethiological, microscopical features, we suggest the treatment and the differential diagnosis.

Abstract
The Authors presented the clinical report of an apical scar because of the rareness of the case and because of the interesting differential diagnosis: this lesion has a cystic radiological aspect and must be differentiated from the real odontogenic cysts of the jaws; the apical scar does not belong to the cystic pathology and represents just a defect of the healing process: no treatment is requested as the apical scar mustn't be considered a pathology.

Abstract
The Authors conclude the chapter about the central intraosseous developmental odontogenic cysts. Some of them are very rare, others are very similar histogenetically with other more frequent cystic lesions of the jaws. Notwithstanding the radiographic and macroscopic aspect apparently similar, these lesions are very different between each other in their biological activity. The classification, suggested by Hoffman, Jacoway and Krolls lists these lesions from the least to the most aggressive. We have here considered the multiple nevoid basal cell carcinoma syndrome, also known as Gorlin-Goltz syndrome, associated to one or more keratinized maxillary cysts, the calcifying odontogenic cyst, the more frequent and well known dentigerous cyst, the lateral periodontal cyst with its uncertain etiology and the harmless eruption cyst.

Abstract
Discussing the central intraosseous developmental odontogenic cysts of the jaws the Authors have followed the classification suggested by Hoffman et Al. that lists the lesions according to their biological activity. After a short foreword about the most important stages of the embryological dental development, grouped in six phases, the Authors referred to the principal concepts emerging from the literature about the most aggressive developmental odontogenic cysts of the jaws: the primordial cyst and the odontogenic keratocyst of which they have outlined a definition, and referred to the clinical, radiological, ethiological and microscopical data, the treatment and the differential diagnosis.
