[Anterior cervical spine hyperostosis--a rare cause of difficult intubation in emergency]. / Hiperostoza cervicala anterioara--o cauza rara de intubatie dificila în urgenta.

DISH (Diffuse idiopathic skeletal hyperostosis) of cervical spine is a rare condition which causes dysphagia in 23% of cases and occasionally dyspnea. The authors report the case of a 74 years old male, known with progressive dysphagia and recurrent episodes of dysphonia and dyspnea, who suffered a sudden episode of respiratory distress that need finaly tracheotomy after ineffective attempts of orotracheal intubation.

Neighbouring relations of the posterior ethmoid studied by axial computed tomography.

The anatomy of the paranasal sinuses is variable and it is important to appreciate their clinical and surgical significance. During both posterior ethmoid and sphenoid sinus surgery, but also for endoscopic approach of pituitary, a good knowledge of the anatomy is essential for understanding the pathological process and to prevent surgical complications (optic nerve, internal carotid artery injury during surgery). Although coronal Computerized Tomography (CT) is the routine procedure performed for functional endoscopic sinus surgery (FESS), axial CT is most useful in demonstrating the anatomy of the posterior ethmoid and the sphenoid sinus. The authors comment the posterior ethmoid cells and its variable relationship with the sphenoid sinus and its intimate association with the optic nerve, for using a pictorial axial CT by studying 50 CT head region.

[Anatomical variations of landmarks in endoscopic surgery of the paranasal sinuses revealed by MRI imaging]. / Variante anatomice ale reperelor din chirurgia endoscopica a sinusurilor paranazale evidentiate imagistic prin RMN.

Continue development of endoscopic techniques of rinosinusal approach involves knowledge about the anatomy of this region, with a three-dimensional orientation before surgery, a therapeutic plan well thought, anticipating the gesture controller, taking into account the particularities of each case. Endoscopic surgical anatomic variants parts at this level can be well identified by imaging methods (CT, MRI). CT study of patients who are candidates for surgery Fess is on top, as the technique of choice. MRI is the imaging method to supply the CT data, providing a study carried out the normal anatomy and standard deviation of the numerous variants, single or in combination. This paper aims a randomized retrospective study of 120 MRI of the head and face region, to investigate and highlight the anatomical variations of structures at this level of impact and those with sinusitis etiopatologia, as well as those with operative risk (bleeding complications, ocular, vital risk) to determine the prevalence in the general population and have to compare the data with the literature. Using all sections (axial, sagittal and coronal) with the aid of different sequences (T1, T2, Flair and diffusion) allowed study of three-dimensional images of whole rhino-sinus-related pathology. Anatomic variations of surgical landmarks have investigated a wide range of expression, which are unique or associated with a complex architecture, with sufficient accuracy and visible on MRI. Their prevalence in the group studied was generally consistent with the literature studied.

[Nickel and magnesium effects in the rat kidney, treated with acid retinoic. Comparative study]. / Efectele comparative ale nichelului si magneziului asupra rinichiului de sobolan Tratat experimental cu acid retinoic.

UNLABELLED: Magnesium and nickel are ions with an important role in the human body, but their effects are not completely understood. AIM: To clarify the actions of magnesium and nickel on the rat kidney, which was experimentally treated with retinoic acid, an important therapeutic agent. MATERIAL AND METHOD: The first lot of animals was the witness lot and didn't receive any substance. The second lot received retinoic acid, 50 mg/kg weight/day for 30 days. The third lot received retinoic acid in the same way and magnesium acexamate, 0.5 mEq /kg weight/day for 30 days. The fourth lot received retinoic acid in the same way and NiCl2, 0.5 mEq /kg weight/day for 30 days. RESULTS: The retinoic acid has a toxic effect on the rat kidney. The magnesium decreases this toxic effect but the nickel increases this toxic effect and destroys some urinary tubes.

[Chief teratogenic factors in facial abnormalities]. / Principalii factori teratogeni la nivelul fetei.

Congenital anomalies of the face mainly originate in chromosomal and teratogenic factors. Cleft lip and cleft palate are common anomalies of the face and palate. Cleft lip, with or without cleft palate, occurs about once in 1000 births. Cleft palate occurs about once in 2500 births. Most cases of cleft lip and palate are determined by multiple factors, genetic and nongenetic, each causing only a minor developmental disturbance. This is called multifactorial inheritance. The purpose of this study is a review on teratogenic factors with action on the newborn face.

[Modern morpho-functional concepts in cephalic arterial distribution]. / Conceptii morfo-functionale moderne in distributia arteriala cefalica.

The present paper provides a general morphofunctional study of the oro-maxillary-facial cephalic arterial area that shows some particular hemodynamic characteristics. The internal maxillary artery supplies a very large territory, with numerous and wide anastomoses. In order to understand the hemodynamic characteristics of this artery, we analyzed some older theories, such as: Ludwig von Bertalanffy's General Systems Theory, Walter Zimmermann's Telome Theory, and some general rheological principles also.

[Temporo-mandibular joint. Morpho-functional considerations]. / Consideratii morfo-functionale asupra articulatiei temporo-mandibulare.

The temporo-mandibular joint is distinguished from most other synovial joints of the body by two features: 1. the two jointed components carry teeth whose position and occlusion introduce a very strong influence on the movements of the temporo-mandibular joint and 2. its articular surfaces are not covered by hyaline cartilage, but by a dense, fibrous tissue. This paper describes the parts of the temporo-mandibular joint: the articular surfaces (the condylar process of the mandible and the glenoid part of the temporal bone), the fibrocartilaginous disc which is interposed between the mandibular and the temporal surface, the fibrous capsule of the temporo-mandibular joint and the ligaments of this joint. All these parts present a very strong adaptation at the important functions of the temporo-mandibular joint.

[Anatomic and anthropologic considerations on mandible]. / Consideratii anatomice si antropologice asupra mandibulei.

The mandible is one of the most important bones of the face, by its function in the temporomandibular joint and by its role in the facial aesthetics. From this reason, our article makes some measurements on the mandible (the mandibular length, the bicondylar breath and the mandibular index). We made the measurements on 20 masculine and feminine skulls.
