THE STUDY OF ACCLIMATIZATION OF GRAPES OF MEDITERRANEAN ORIGIN TO THE WEATHER CONDITIONS OF THE WINE-GROWING REGIONS OF SEGARCEA
This study was carried out during 2019-2020 on plots belonging to the wine-growing areas of Segarcea, famous wine areas in point of extracting red wine with remarkable qualities in the south of the country. The significance of the work consists in improving the useful climate of the wi ne area of Segarcea by introducing into the culture beside black grapes varieties, renowned varieties like Feteascăneagră, Merlot, Cabernet-Sauvignon, Pinot noir, etc., other grape varieties of Mediteranean origin, such as Syrah and Marselan. The aim is to rigorously monitor the weather conditions with a direct impact on the soils with a production potential, observing the dynamics of its establishment and maturation index for each variety during the period studied
Carotid paragangliomas: case report and imaging review
Background: Presentation of case reviews depicting the imaging characteristics of carotid paragangliomas, associated with a thorough analysis of the anatomical morphological features and the current therapeutic strategies.Materials and methods: We present the cases of 3 patients diagnosed with carotid paragangliomas in our clinic, illustrating diagnostic imaging elements by computer tomography (CT) and magnetic resonance imaging (MRI), but also the postoperative aspect of the carotid system, with respective anatomical, clinical and surgical considerations.Results: The imaging aspect of the carotid paragangliomas is characterised by a mass of soft tissue with intense contrast enhancement and with “salt and pepper” MRI appearance on conventional spin-echo sequences. The postoperative evolution of the patients included in the article was favourable, without any perioperative complications or signs of local tumour recurrence.Conclusions: Carotid paragangliomas are rare, often asymptomatic tumours, but with potential for increased malignancy, which raises the need for good knowledge of the cervical region pathology as well as the features of neuroendocrine tumours. CT and MRI examinations are essential for diagnosis, staging and, implicitly, for establishing the therapeutic strategy
Spinal schwannomatosis of the cauda equina in the absence of neurofibromatosis: Case report and treatment strategies
Schwannomatosis is a rare tumor syndrome characterized by the presence of multiple benign non-vestibular, non-intradermal schwannomas and by the absence of neurofibromatosis type 1 or 2 syndromes. Multiple schwannomas are clinically and genetically distinct from neurofibromatosis, and the main treatment in case of symptomatic lesions is represented by surgical resection. In case of asymptomatic lesions, the indicated treatment is neuroimaging follow-up (MRI). We are presenting the case of a patient with three schwannomas of the cauda equina, as well as the treatment strategy in the case of this rare pathology

Choledocoscopy in the surgery of mechanical jaundice
Universitatea de medicina si farmacie “Gr. T. Popa”, Iasi, clinica a IV-a chirurgie, Al XI-lea Congres al Asociației Chirurgilor „Nicolae Anestiadi” din Republica Moldova și cea de-a XXXIII-a Reuniune a Chirurgilor din Moldova „Iacomi-Răzeșu” 27-30 septembrie 2011Scopul lucrării: Diversitatea etiopatogenică a icterului mecanic justifică explorarea coledocoscopică, necesară unui diagnostic de certitudine. Material
şi metodă: Între anii 2002 - 2011 am utilizat coledocoscopul flexibil la 58 de pacienți internați cu icter mecanic. La 21 (36,2 %) dintre aceştia icterul
s-au dovedit a fi de etiologie neoplazică: 5 (8,6 %) cazuri cu ampulom vaterian (care au beneficiat de duodenopancreatectomie cefalică), 14 (24,1 %)
cazuri cu neoplasm al capului de pancreas şi două (3.4 %) cazuri cu colangiocarcinom). Ceilalți 37 (63,8 %) de pacienți au avut o etiologie litiazică,
la care coledocolitotomia asistată coledocoscopic şi asociată colecistectomiei a permis vindecarea. Rezultate. Discuții: Dintre pacienții cu suspiciune
de icter mecanic neoplazic, în două (3,4 %) cazuri a fost necesară coledocoscopia care a certificat diagnosticul de colangiocarcinom atât prin aspectul
imagistic, dar mai ales datorită posibilității prelevării biopsiei şi examenului histopatologic. În explorarea icterului mecanic. cu etiologie litiazică examenul
coledocoscopic permite vizualizarea calculilor în 16 (27,5 %) cazuri la care celelalte explorări imagistice erau neconcludente. În toate cazurile
controlul coledocoscopic a certificat absența calculilor în calea biliarặ principalặ la finalul intervenției, oferind astfel siguranță privind acuratețea
actului chirurgical. Concluzii: Coledocoscopia aduce siguranță în chirurgia căii biliare principale atât în ceea ce priveşte diagnosticul, permițând
vizualizarea şi prelevarea biopsiei în leziunile tumorale ale căii biliare principale cât şi în tratamentul litiazei biliare, oferind posibilitatea controlului
imediat (intraoperator) al căii biliare principale după coledocolitotomie.Abstract. Background. The diverse etiology of mechanical jaundice requires a choledocoscopy to allow a correct diagnosis. Methods: Between 2002
and 2011, we used flexible choledocoscope, in 58 patients with mechanical jaundice admitted in our clinic. 21 (36, 2 %) cases proved to be of neoplastic
etiology: 5 (8, 6%) cases diagnosed with vaterian ampuloma (treated by cephalic duodenopancreatectomy), 14 (24, 1 %) cases with pancreatic head
cancer and two (3, 4 %) cases with cholangiocarcinoma. The remaining 37 (63, 8 %) cases were caused by lithiasis, treated by choledocolhitotomy associated with choledocoscopy and cholecystectomy. Results. Discussion: Among patients with suspected neoplastic mechanical jaundice, in two (3.4 %)
cases choledocoscopy was necessary, in order to sustained the diagnosis of colangiocarcinoma, by macroscopically appearance, and also by the biopsy
sampling and histological examination. In mechanical jaundice of lithiasis etiology, the choledocoscopy permitted the visualization of stones in 16 (27,
5%) cases in which, other imagistic investigations were inconclusive. In all cases choledocoscopic control certified the absence of gallstones in the bile
duct at the end of the surgical procedure, and thereby provides safety of the surgical act. Conclusions: Choledocoscopy adds certainty in the main bile
duct surgery both in terms of correct diagnosis, allowing visualization and biopsy sampling of the main bile duct in tumor lesions and in treatment
of gallstone disease, allowing immediate control of the main bile duct after choledocolithotomy
Extradural autologous temporal muscle graft mimicking a meningioma: Case report
Meningiomas are the most common dural tumour, but there are also many other dural masses which mimic their appearances, such as neoplastic and non-neoplastic lesions. In this paper we report another mass which may mimic a dural lesion, namely a muscle graft harvested from the temporal site and left in situ, used to achieve haemostasis in a posttraumatic temporal extradural hematoma in a young male patient. Solid knowledge of differentiating neuroimaging characteristics of dural masses, as well as its corroboration with the patient’s medical history are extremely helpful in establishing an accurate diagnostic
The employee as 'Dish of the Day’:human resource management and the ethics of consumption
This article examines the ethical implications of the growing integration of consumption into the heart of the employment relationship. Human resource management (HRM) practices increasingly draw upon the values and practices of consumption, constructing employees as the ‘consumers’ of ‘cafeteria-style’ benefits and development opportunities. However, at the same time employees are expected to market themselves as items to be consumed on a corporate menu. In relation to this simultaneous position of consumer/consumed, the employee is expected to actively engage in the commodification of themselves, performing an appropriate organizational identity as a necessary part of being a successful employee. This article argues that the relationship between HRM and the simultaneously consuming/consumed employee affects the conditions of possibility for ethical relations within organizational life. It is argued that the underlying ‘ethos’ for the integration of consumption values into HRM practices encourages a self-reflecting, self-absorbed subject, drawing upon a narrow view of individualised autonomy and choice. Referring to Levinas’ perspective that the primary ethical relation is that of responsibility and openness to the Other, it is concluded that these HRM practices affect the possibility for ethical being
