[Splenic sarcoidosis diagnosed by US-guided biopsy: About a case]

INTRODUCTION

Splenic localisation of sarcoidosis is common but rare as unique location. We report a case diagnosed by US-guided biopsy.

OBSERVATION

A 42-year-old woman presented atypic and recidivant epigastric pain. Abdominal ultrasound showed splenic hypoechoic nodules not characterizable with CT or MRI. PET-CT revealed hypermetabolism without any other abnormal metabolic activity. US-guided biopsy with small needle achieved diagnosis of isolated splenic sarcoidosis.

CONCLUSION

Diagnosis of splenic nodular sarcoidosis can be challenging without any other localization. Splenic biopsy achieved diagnosis. This procedure is associated with a low risk of complications - in particular hemorragic ones. Diagnostic splenectomy should be an exceptional intervention.

[Early detection of autism spectrum disorders]

The evaluation of the development of young children had to consider the possible detection of neurodevelopmental disorders in particular autism spectrum disorders. When a child of 18 months has a developmental language delay or a defect in social contact, the hypothesis of autism must be considered through a clinical evaluation. We will point out some clinical guidelines and some early signs to detect the trouble and to propose early treatment interventions. This will help to develop specific skills of the child aiming at influencing positively clinical evolution and reducing mental retardation.

Microscopic evaluation regarding time behavior of orthodontic cements used for disjunctor cementing

In order to fulfill their function, orthodontic devices must be cemented on teeth using orthodontic rings. The retention of the orthodontic ring is influenced mainly by the type of dental-ring adhesion. This study was initiated to determine possible microleakage events while using zinc phosphate cement Adhesor (Spofa Dental), conventional glass ionomer Ketac Cem (3M ESPE) and Fuji Ortho (GC) and a compomer Transbond Plus (3M Unitek). The results of the study are consistent with those reported in the literature reference, the compomer is the preferred adhesive material for cementing the orthodontic rings, compared to conventional glass ionomer cements and zinc-phosphate cement.

Intervention of the occlusion relations in the appearance of the modifications in sagittal and transversal plan in the anomalies of the class III angle

During the development of the neuronic and visceral cranium, an important number of factors, not only genetic, but also functional, led to the apparition of some different aspects of growing at the level of each section: the basis of the cranium, the basis of the maxillary, dental alveolus, dental arch. All these "aggravating" or "compensatory" changes are added to the level of the occlusion plan, leading to the establishment of the occlusion relations in the three plans. From now on, the occlusion will directly influence the development at the level of the above-described sections.

De-Nol in the treatment of reflux esophagitis

Twenty-eight patients with histologically proven reflux esophagitis were randomly allocated to receive either De-Nol (tripotassium dicitrate bismuthate) or placebo for three weeks. Significant decreases in symptoms frequency and severity were noted in De-Nol group comparing with placebo group (p less than 0.01). Objective improvement in esophageal endoscopic appearance was obtained in 78.5% of the patients treated with De-Nol and only in 14.2% of those receiving placebo. De-Nol appears to be an effective drug in the treatment of reflux esophagitis, but this should be confirmed by further studies.

Protein content and thyroid hormone release in vitro by differentiated thyroid cancer cells in the presence of estradiol, dehydroepiandrosterone, polypeptidic hormones and pesticides

The reactivity of thyroid cancer cells treated with estradiol (E) and dehydroepiandrosterone (DHA) in the presence of other hormones (TSH, STH, insulin), myopeptide and some pesticides (aminotriazole--ATA, atrazine--ATZ, prometryne--P and ATC) proved to be active in the culture medium. Protein synthesis in sclerosing folliculo-papillary cancer cells under the treatment applied is more markedly inhibited by DHA than by E in the culture medium is compared to the control lots. Tg1 and T3 release into the culture medium under the action of T4 and TSH decreases progressively going from the control to the treated lots, in the presence of E and DHA. STH inhibits Tg1 and T3 secretion in thyroid follicular carcinoma, whether or not E or DHA are present in the culture medium.
