Diagnostic Difficulties of Neurological Complications After Surgical Treatment of Acute Ascending Aorta Disection - A Case Report

Adverse drug reactions deteriorate patient state, delay proper diagnosis and therapy. Drug-induced extrapyramidal syndromes caused by use of receptor D2 antagonists are relatively rare. We present a case of acute dystonia with upper limbs tremors after medication with metoclopramide and neuroleptic drugs in young patient operated on acute aortic dissection. Besides a rare comlication in the shape of right temporo-maxillary joint luxation and somatic symptoms of anxiety reaction occured, what made difficult the proper diagnosis and fast treatment.

Abstract

The hyperfine fields and atomic ordering in Ni1− xFexMnGe (x = 0.1, 0.2, 0.3) alloys were investigated using X-ray diffraction and Mössbauer spectroscopy at room temperature. The X-ray diffraction measurements show that the samples with x = 0.2, 0.3 crystallized in the hexagonal Ni2In-type of structure, whereas in the sample with x = 0.1, the coexistence of two phases, Ni2In- and orthorhombic TiNiSi-type of structures, were found. The Mössbauer spectra measured with x = 0.2, 0.3 show three doublets with different values of isomer shift (IS) and quadrupole splitting (QS) related to three different local surroundings of Fe atoms in the hexagonal Ni2In-type structure. It was shown that Fe atoms in the hexagonal Ni2In-type structure of as-cast Ni1− xFexMnGe alloys are preferentially located in Ni sites and small amount of Fe is located in Mn and probably in Ge sites. The spectrum for x = 0.1 shows the doublets in the central part of spectrum and a broad sextet. The doublets originate from the Fe atoms in the paramagnetic state of hexagonal Ni2In-type structure, whereas the sextet results from the Fe atoms in orthorhombic TiNiSi-type structure.
