Background and aim of this clinical case presentation is to reveal the importance of early nerve injury diagnosis and surgical treatment in war wounded patients. Methods. The author treated patients in Amman Charity Hospital were among different plastic surgery cases where limb nerve injuries with nerve grafting indication. The presented case was treated with autologus sural nerve graft. Results were evaluated at 3 months after the surgery and revealed detectable nerve conductibility at the Electromiography test. In conclusion, in cases with delayed nerve repair surgical treatment in war wounded
Epidermoid squamous-cell carcinoma is by far the most common malignant tumor of larynx (95-96%), representing 1.6-2% of cancers in men and 0.2-0.4% of malignancies in females, with a world growing incidence and a slight dominance in urban areas. By exposing cells and tissues to UV in part by non-radiative light, the excitation of naturally occurring chromophores occurs deactivations, in part via fluorescence emission. Using laser induced autofluorescence (LIAF) in natural tissues not impregnated with photosensitizers as a noninvasive autofluorescence technique for both diagnosis and intraoperative assessments of laryngeal cancer we can improve the tumor malign identification in vivo. A total of three laryngeal biopsies (i.e. three pairs of tissues, each pair containing a healthy and a tumor tissue sample extracted from the same patient) were considered in this study. The samples were collected from patients previously diagnosed with stage T3 laryngeal carcinoma. Immediately after the surgery fragments of normal tissue and neoplastic tissue were collected, fragments of which later, after freezing, were sectioned in 25-30 μm thickness slices and stretched to quartz slides. All samples were subjected to controlled laser irradiation using a pulsed diode laser (λ=375nm, pulse width=87ps, frequency 31MHz) and the autofluorescence and its lifetime were collected using two optical fibers (inner diameter 400µm and 1500µm, respectively) positioned in a 45o geometry. The signals were recorded using a spectrograph and a photo-sensor module, the output of which was fed to a digital oscilloscope. lifetime We assessed the measurements in order to identify the differences between healthy and tumoral laryngeal tissue and outlining them, in terms of differences between the laser autoinduced fluorescence averaged intensity. The results determined the usefulness of laser induced spectroscopy in the diagnosis of laryngeal squamous cell carcinoma, discriminating between the malignant and normal tissue by analyzing the differences in spectral autofluorescence intensity and autofluorescence lifetime.

A finite element simulation of the mechanical static features for a modified short hip endoprosthesis was performed. The corkscrew-like femoral stem was modified introducing more turns of the thread. By such an approach it is expected that for some cases the mechanical fixation of the prosthesis to the bone will be improved or the use of the cement for bonding is not necessary. Our scenario was estimated for titanium and stainless steel, and both materials show good safety factors. Mechanical stress is expected to be distributed more uniform in the bone for the new design with more turns of thread.
Introduction: Starting September 2010 in Romania was created the Military Emergency Medical Service (SMMU) by the Ministry of National Defense, which has as main mission to provide first aid and save the lives of military personnel during military operations using special equipped MEDEAVC aircraft. Nationwide exist the national emergency system which operates thru 112- SMURD acting in support of the civilian population. In case of accidents with multiple victims the experience has shown the need for collaboration between the two systems, in order to save lives. In the last 5 years there has been an increasing Airlift missions (MEDEVAC) with multiple victims executed by joint civil-military medical teams using military aircraft. Material and methods. This paper provides a review of the most important aspects of particularities, advantages and disadvantages of this type of medical transport using the MEDEVAC missions based study carried out by the Air Force in recent years. Results and conclusions. Performing these tasks presents challenges to mission planning, use of medical equipment and procedures, command-control system, exercise programs jointly joint medical teams and, of course, managing a large number of patients in flight. The large number of patients transported safely and in the shortest time, regardless of weather conditions recommends this type of medical intervention. Given the Romanian military presence in various theaters and that NATO strategic medical evacuation is a national responsibility, the capacity of air transport in case multiple casualties is a priority.
This study analyzes the satisfaction of the patients with radical prostatectomy according to the signs and symptoms included in the EORTC QLQ – C30 and EORTC QLQ – PR25 questionnaires, including their relation with the health state that influences the pre and postoperative life quality. Fifty patients with prostate cancer in a localized stage were studied and analyzed in a prospective manner and for a period of 12 months, before and 6 months after the radical prostatectomy. In choosing the patients, the common denominator was the use of the same postoperative plan and the lack of postoperative complications, as well as the lack of chronic diseases. Erectile dysfunction, urine incontinence were quite frequent after radical prostatectomy, while the urinary obstruction and the weak urinary stream were less frequent. In this regard, people noticed a significant decrease of life quality. Although the study addressed a small group of patients, the results are similar to those belonging to other clinical studies. Even if the aspect of life quality is more rarely taken into account, the questionnaires regarding the life quality are specific, useful and quite cheap in evaluating different therapies.
Background and objective: Contrast-enhanced ultrasound, used to assess atherosclerotic carotid plaques, improves visualization of vessel wall irregularities and depicts intraplaque neovascularization. This article illustrates the use of contrast-enhanced ultrasound in the risk assessment of carotid atherosclerotic lesions, especially in challenging plaques evaluation. Materials and methods: For 23 patients with difficult duplex ultrasound examination due to carotid tortuosity or calcifications we assessed plaque morphology (contour, echogenicity and stenosis degree) using contrast substance (Sonovue, Braco) with dedicated vascular low mechanical index CPC software. Conclusion: Contrast-enhanced ultrasound is a new, noninvasive, and safe procedure for imaging carotid atherosclerotic lesions. It is a valuable tool for evaluating the vulnerable plaque at risk for rupture and for the diagnostic of the development and severity of systemic atherosclerotic disease
