Analysis and structural characterization of pigments and materials used in Nicolae Grigorescu heritage paintings.

The combination of various mobile, non-invasive techniques (IR reflectography technique, optical microscopy, XRF, Raman and NIR spectroscopies) and lab-based devices (FTIR and XPS spectroscopies, SEM-EDX microscopy) lead to the first exhaustive investigation of pigments and materials used by the famous Romanian painter Nicolae Grigorescu in three cultural heritage paintings. The study of a large number of spots and samples allowed a rigorous analysis and a far-reaching insight into his work.

[Complications of Crohn's disease (Clinical and anatomopathological observations on 13 cases)].

Malignization of Crohn disease remains the most severe complication, both due to its intrinsic gravity and to the major complications that it may induce such as: peritonitis--following suppurations and perforation of the involved intestinal segment; intestinal sub-occlusion or mechano-inflammatory occlusion, either tumoral or chronic leading to stenosis of the intestine; hemorrhage. Malignization of Crohn disease was found in 53,84% of the cases (7 out of a total of 13 cases, between 1968 and 1974). This allows to conclude that Crohn disease can be considered as a pre-cancerous disease.

[Experimental basis for a new surgical-therapeutic method for duodenal ulcer: gastric mucoslerosis].

On the basis of studies carried out by chronic experiments in dogs the authors noted, by clinical, chemical, radiological and histological methods, that the chemical sclerosis of the gastric mucosa performed with a sterile, fresh hypertonic solution of glucose at 60%, injected in the sub-mucosa, represents an intervention which is:--physiological, since the sclero-distrophy is achieved of the acid-secreting glands and "targeted" intra-gastric vago-sympathic denervation, while the storage function of the stomach is maintained;--feasible, since it can be easily performed from the technical view point, without hemorrhagic, perforative intra-operatory risks or hepato-renal toxicity;--fiable, since it was constantly accompanied by good clinical and functional results. The radiological examination of the barium passage in the stomach, antrum, pylorus and duodenum is normal.

[Carcinoid tumors of the digestive tract].

With reference to 6 cases of carcinoid tumours of the digestive tract the authors discuss the clinical aspects, emphasizing the utility of the paraclinical tests and the benefit of an early diagnosis, in the premetastatic phase, when surgery gives the best results.
