When a Pathological Forearm Fracture Led to Explore the Neck: About a Case.

The majority of patients with parathyroid carcinoma (PC) have significant clinical signs and simultaneous symptoms related to the unregulated hypersecretion of parathyroid hormone (PTH) by the tumor. The aim of this case was to report a patient presenting an isolated bone fracture leading to the diagnosis of PC. A 20-years-old female patient presenting a fracture of both bones of the forearm following a fall from her own height. Imageries showed diffuse bone demineralization. Biology revealed malignant hypercalcemia at 4.1 mmol/L and PTH at 1331 pg/mL. Bone densitometry showed severe osteoporosis with a femoral and lumbar T-score < - 3DS. Imageries showed a right parathyroid mass of 32 mm. An one-piece excision of the pathological gland, right thyroid lobectomy and ipsilateral central lymph node dissection were performed. Postoperatively, the patient presented a hungry bone syndrome with severe hypocalcemia and required substitutive treatment. PTH on day 1 was normal. Pathology analysis found a PC with Ki67 at 3%, lymph node removal was negative. Complete one-piece surgical excision is the only potentially curative treatment for PC. Preoperative suspicion and intraoperative recognition of malignant features is important in order to propose an appropriate compartmental surgery, which can provide the lowest possible recurrence rate.

Performance of 18F-sodium fluoride positron emission tomography with computed tomography to assess inflammatory and structural sacroiliitis on magnetic resonance imaging and computed tomography, respectively, in axial spondyloarthritis.

PURPOSE: To assess increased sacroiliac joint (SIJ) uptake on 18F-NaF PET/CT and to compare with MRI for inflammation and with CT scan for structural damages in a population of 23 patients with spondyloarthritis (SpA). METHODS: Twenty-three patients with active SpA according to the Assessment of SpondyloArthritis international Society (ASAS) and/or modified NY criteria were included. All patients had a pelvic radiograph, MRI, and CT scan of the SIJ and 18F-NaF PET/CT examinations within a month, analyzed by three blinded readers. MRIs were assessed according to the ASAS criteria and SPARCC method. On CT scans, erosion and ankylosis were quantified using the same methodology. On the 18F-NaF PET, abnormal uptake was assessed using a qualitative method inspired by the ASAS criteria and two quantitative approaches (the PET-activity score according to the SPARCC method and Maximum Standardized Uptake Value (SUVmax)). RESULTS: Structural sacroiliitis was observed on 7 radiographs and 10 CT scans; 10 MRIs showed inflammatory sacroiliitis, and 20 patients had a positive PET. The inter-reader reliability was good for the PET activity score and good to excellent for the SUVmax. A positive PET was not correlated with a positive MRI or with a structural sacroiliitis on CT scan. The PET-activity score and SUVmax were correlated with the SPARCC inflammation score but not with erosion or ankylosis scores on CT scan. CONCLUSION: Abnormal uptake by the SIJ on 18F-NaF PET is more frequent than inflammatory and structural sacroiliitis in a population of SpA patients. The PET activity score and SUVmax had good correlations with inflammatory sacroiliitis but not with structural lesions on CT scan.

Performance of 18F-sodium fluoride positron emission tomography with computed tomography to assess inflammatory and structural sacroiliitis on magnetic resonance imaging in axial spondyloarthritis.

OBJECTIVES: To assess increased sacroiliac joint (SIJ) uptake on 18F-NaF PET/CT according to a qualitative and quantitative approach and to compare with MRI SIJ assessments for structural and inflammatory sacroiliitis in a population of 23 patients with spondyloarthritis (SpA) (IDRCB: 2012-A00568-35; ClinicalTrials.gov: NCT 02869100). METHODS: This single-center prospective study included 23 patients with active SpA according to the ASAS and/or modified NY criteria. All patients had a pelvic AP-view radiograph, MRI of the SIJ and 18F-NaF PET/CT examinations within a month, which were analysed by three blinded readers. For MRI data, the SIJs were assessed according to the ASAS criteria and SPARCC method for scoring structural lesions (erosion, sclerosis, fat metaplasia, backfill and ankylosis) and inflammation. On the 18F-NaF PET, the SIJs were scored according to a slice-by-slice approach. Abnormal uptake was assessed using a qualitative method inspired by the ASAS criteria and two quantitative approaches (the PET-activity score according to the SPARCC method and the maximum standardised uptake value (SUVmax) for each SIJ). RESULTS: Structural sacroiliitis was observed on 7 radiographs and 15 MRIs. 10 MRIs showed inflammatory sacroiliitis (mean SPARCC 18.7). Twenty patients had a positive PET with a mean PET-activity score of 18.2 (±8.7). The mean SUVmax for a positive PET was 1.78 vs. 1.45 for a negative one. The inter-reader reliability was good for the PET activity score (ICC= 0.56 [IC-95: 0.32; 0.76]) and good to excellent for the SUVmax (ICC=0.70-0.90 [IC-95: 0.41; 0.96]). According to a binary approach, a positive PET was not correlated with a positive MRI for structural sacroiliitis. The PET-activity score (r=0.61, p=0.001) and SUVmax (r=0.56, p=0.004) were correlated with the SPARCC inflammation score but not with structural sacroiliitis or for SPARCC structural lesions. CONCLUSIONS: Abnormal uptake by the SIJ on 18F-NaF PET is more frequent (87.0%) than inflammatory (43.5%) and structural sacroiliitis (65.2%) on MRI in a population of SpA patients. The PET activity score and SUVmax had good correlations with inflammatory sacroiliitis but not with structural lesions on MRI.

[Environment and addictive behaviors]. / Conduites addictives et environnement.

Consumer society creates the emergence of addictive behaviors and environments of the subject "shape" the use of psychoactive substances. The family approach is to search out a guilt of members to understand family dynamics and enable young people to emancipate themselves from the family model. The social environment contributes to the marginalization of drug users "pathologizing" his conduct. Offer help without preconditions and a relationship based on a therapeutic alliance can contribute decisively to the recovery of an addict. The prison is a place of initiation of use and consumption of psychoactive substances despite the offer of specialized treatment. Measures of risk reduction of HCV/HIV infection and alternatives to incarceration should complete it. At workplace, consumption can be considered as a mean of doping to be more "efficient", but also as an attempt to withstand the stresses and changes in working conditions in the context of individualization and a loss of marks related to the new way of organizing work.

[Alcohol, an addiction like any other]. / L'alcool, une addiction comme les autres.

The current treatment available to people in difficulty with regard to their consumption of alcohol is not merely limited to forced abstinence. It benefits from the advances made in addictology and research into treatment based on the concept of controlled consumption. In the framework of a therapeutic alliance, multidisciplinary teams offer medication-based treatments and individualised and diversified psycho-social treatment.

Transfusion related acute lung injury (TRALI) caused by red blood cell transfusion involving residual plasma anti-HLA antibodies: a report on two cases and general considerations.

TRALI is considered a serious hazard among immune complications of blood transfusion and its occurrence is admitted to be globally underestimated. Each type of blood product is likely to cause TRALI. We report here on two consecutive observations of TRALI caused by red blood cell concentrates, in which anti-HLA class I and class II antibodies resulting from post-gravitational allo-immunization were evidenced in donors. HLA class I and II antigenic community between recipients and donors' husbands were found and strong reacting IgG antibodies directed at several of those common antigens were detected in the donors' serum. Both donors had more than 3 pregnancies, raising the issue of blood donor selection or of plasma reduction for cellular products.

Coniosetin, a novel tetramic acid antibiotic from Coniochaeta ellipsoidea DSM 13856.

The coprophilic ascomycete Coniochaeta ellipsoidea DSM 13856 forms the new antibiotic coniosetin (1) in surface cultures grown on a medium containing malt extract and oatmeal. The structure of the compound C25H35NO4, MW 413, was determined by 2D-NMR and mass spectrometric studies. Coniosetin belongs to the class of tetramic acids; it consists of a substituted aliphatic bicyclic ring system linked to a tetramic acid subunit through a carbonyl center. The absolute configuration was determined by measuring its circular dichroism spectrum and comparing the data with those of equisetin. Coniosetin has a pronounced antibacterial and antifungal action, inhibiting even multi drug-resistant strains of Staphylococcus aureus at a concentration of 0.3 microg/ml, though it is inactive against Gram-negative bacteria.
