We report a case of a 42-year-old male patient who was transferred to our emergency department suffering from a gunshot wound in his left lateral thigh. The patient was haemodynamically stable, and the physical examination of the abdomen and thorax was unremarkable. There was no obvious exit point and there were no other injuries. The radiologic control of the left thigh showed an intact femur and multiple pellets within the adjacent soft tissues. Routine X-ray evaluation of the thorax revealed a small-sized round object of metal density—possibly a migrated pellet—in the proximity of the right heart atrium. Computed tomography imaging confirmed this finding and showed no other cardiac or mediastinal injury. Ultrasonography of the heart was unremarkable as well. The patient was managed conservatively for the discovered pellet, and remained asymptomatic throughout the entire hospital stay, and 6 months after the discharge. Pellet migration or embolism should be suspected in any gunshot victim without a corresponding exit wound or when the signs and symptoms do not correlate with the suspected course of the missile. Conservative management remains the first choice in asymptomatic patients, although close monitoring at first and regular observation after discharge are indicated.

Low Dose Computed Tomography

Existing fractional-order Perona-Malik Diffusion (FOPMD) algorithms used in noise suppressing suffer from undesired artifacts and speckle effect, which hamper FOPMD used in low-dosed X-ray computed tomography (LDCT) imaging. In this paper, we propose a new FOPMD method for low-dose computed tomography (LDCT) imaging, which is called regularized fully spatial FOPMD (RFS-FOPMD), whose numerical scheme is also given based on Grünwald-Letnikov derivative (G-L derivative). Here, fully spatial FOPMD represents all the integer-order derivatives (IODs) in the right hand of Perona-Malik Diffusion (PMD) which are replaced by fractional-order derivatives (FODs). Since the new scheme has advantages of both regularization and FOPMD, it has good abilities in singularities preserving while suppressing noise. Some real sinogram of LDCT are used to compare the different performances not only for some classical but also for some state-of-art diffusion schemes. These schemes include PMD, regularized PMD (RPMD), and FOPMD in (Hu et al. 2012). Experimental results show that besides good ability in edge preserving, the new scheme also has good stability for iteration number and can avoid artifacts and speckle effect with suitable parameters.

Objectives: Multiple myeloma (MM) is characterized by the occurrence of osteolytic lesions. MM treatment usually involves antiresorptive drugs (mainly bisphosphonates). Case Report: A patient with an MM presented osteolytic lesions of the mandible. Extraction of teeth 45 and 46 was performed 5 years after the diagnosis of periodontitis. Four months later, osteonecrosis of the jaw (ONJ) was diagnosed at the extraction site. X-ray showed an extension of osteolytic lesions on the right side, close to the extraction site, without modification of the lesions on the left side. Two months later, a curettage was performed because of a painful bone sequestration. X-ray showed an extension of the osteolytic lesions on the right side. Results: Histological analysis found a vascularized plasmacytoma of the soft tissues around the ONJ. Analysis of the bone showed mixed lesions with osteonecrotic areas and living bone resorbed by active osteoclasts surrounding a plasmacytoma. The surface area of the osteolytic foci has considerably increased only close to the extraction site. Conclusions: Tooth extraction triggered an ONJ associated with bisphosphonate treatment. However, it also seemed to induce a considerable proliferation of plasma cells at the extraction site; we hypothesize that it is due to the increase in bone remodeling related to the surgical trauma.

This study analyzes the earliest known case of surgical extraction of the lower third molars, observed in a cranial series from Pucará de Tilcara fortress (15th–16th centuries AD), northwestern Argentina, excavated in 1908–1910. Crania were transported to the Kunstkamera in 1910 under an exchange project. Traces of dental surgery were registered in the mandible of a male aged ~40. Both third molars had been extracted after the removal of soft tissues and parts of the alveoli. Teeth were extracted by scraping alveolar walls with semicircular movements. The results of scanning electron microscopy, X-ray fluorescence, and X-ray microanalysis suggest that a stone tool was used. The results of macroscopic and CT analysis suggest that the surgery was motivated by the exacerbation of chronic periodontal disease and probably by caries. The left third molar was extracted without complications 2–3 months before the individual’s death. On the right side, the pathological process continued, culminating in osteomyelitis and its complications. The surgeon’s skill notwithstanding, the extraction of the right third molar did not cure the patient, who died, apparently following the destructive stage of acute osteomyelitis complicated by orofacial phlegmon. Our findings suggest that the level of dental surgery practiced in the Inca Empire was ahead of the diagnostic expertise.

Introduction: Extramedullar plasmocytoma (EMP) is a plasma cell disease, such as solitary plasmocytoma of the bone and multiple myeloma. It is developed in the soft tissues. Observation: A 79-year-old patient consulted for a painful tumefaction of the gum associated to a radiolucent area on the right side of the mandible on the panoramic x-ray. After surgical enucleation, histological examination showed that the diagnosis was either an IgA extramedullar plasmocytoma or a multiple myeloma. The spreading assessment eliminated the diagnosis of multiple myeloma. The patient was then treated with radiotherapy. Discussion: EMP is a rare tumoral disease. Few cases described oral localisation. The main differential diagnosis, that must be excluded is multiple myeloma. Transformation in multiple myeloma exists. The first intention treatment is radiotherapy of the lesion. Conclusion: EMP of the oral cavity is very rare. After treatment, follow-up is required to detect second localisation or progression in multiple myeloma.

Abstract Introduction. Being a default transradial access center we have encountered the need for alternative to the right radial artery. Determining the most frequent alternative access strategy for PCI in STEMI patientswasthe focus of our study. We sought to analyze whether the wrist access strategy impacts procedure time and success rate particularly for the STEMI interventions where time is of paramount importance. Methods. During four years, in our Center 2624 consecutive all-comers STEMI patients underwent urgent coronary intervention. TRA was used as the first-choice access strategy. We sought to assess crossover rate and safety of preferable access strategy. Crossover occurred according to the operator's decision. Primary outcomes were: access site crossover rate and In Lab time, secondary outcomes were PCI time, X-ray time, mortality and MACE at 30 days and at 6 months. Results. Overall crossover rate from default radial was 5.4% (144 out of 2624 patients). We treated 98.7% (2589) patients by wrist access and only 1.3% (35) patients with TFA. Crossover towards left radial occurred in 47.9% (69 out of 144 patients), towards ulnar 27.8% (40 patients) and towards TFA only 24.3% (35 patients). The meanIn-Lab time 40.4±17.7 minutes, PCI time was 21.4±7.4 min, X-ray time 9.2±4.7 minutes. Survival outcomes at 30 days were: MACE rate of 6.6% (174 patients), mortality rate of 5.0% (131 patients). At six months MACE rate was 8.6% and mortality rate was 5.6%. Conclusions. Default radial access is associated with alow crossover rate. Crossover towards femoral occurred less frequent than ulnar artery access.Complete wrist access strategy is safe and feasible for STEMI interventions with low mortality and MACE rate in unselected all-comers cohort.

Currently, more than 58 skeletal anomalies and pathologies are known in the recent Squamata reptiles. In this paper, eight pathologies of a complex nature are described in Agamidae and Lacertidae: Paralaudakia caucasia (Eichwald, 1831) and Lacerta agilis Linnaeus, 1758. Description of tail pathologies was carried out based on the analysis of X-ray images and on the results of computer microtomography. In the specimen of P. caucasia (ЗИН 19116.1) complete ablation of the caudal vertebra was revealed, which provoked the detachment of chevron and the proliferation of soft tissues. In some Agamidae, after pseudoautotomy, partial ablation of the caudal vertebra occurs to promote wound healing. Complete ablation of the distal caudal vertebra has not been previously reported in literature. In females of L. agilis, deformation of the right transverse process of the vertebra with “false bifurcation” without the formation of a cartilaginous tube (VOLSU 98.2), scoliosis, hematoma and callus on the cartilaginous tube were noted, as well as the absence of an autotomy plane in the postpygal vertebra (ZIN 31549). An unusual pathology in L. agilis (ZIN 31549) is the absence of an autotomy plane in the postpigal vertebra and of its anterior neural spine. The loss of the plane of autotomy during ontogeny is characteristic of some Iguanidae, but it has not been previously noted in Lacertidae. The described cases of anomalies expand the spectrum of known pathologies in reptiles.

Low temperature x-ray microanalysis (LTXM) of solid biological materials has been documented for Lemna minor L. root tips. This discussion will be limited to a demonstration of LTXM for measuring relative elemental distributions of P,S,Cl and K species within whole cells of tobacco leaves.Mature Wisconsin-38 tobacco was grown in the greenhouse at the University of California, Berkeley and picked daily from the mid-stalk position (leaf #9). The tissue was excised from the right of the mid rib and rapidly frozen in liquid nitrogen slush. It was then placed into an Amray biochamber and maintained at 103K. Fracture faces of the tissue were prepared and carbon-coated in the biochamber. The prepared sample was transferred from the biochamber to the Amray 1000A SEM equipped with a cold stage to maintain low temperatures at 103K. Analyses were performed using a tungsten source with accelerating voltages of 17.5 to 20 KV and beam currents from 1-2nA.
