Improved immediate postoperative pain following laparoscopic inguinal herniorrhaphy using self-adhering mesh. The importance of clinical practice guidelines
Over the past decades, clinical guidelines have increasingly been accepted as a fundamental tool to improve the quality of care received by patients. We recognize the important contributions made by Hernia in helping surgeons at the bedside become more efficient, through the publication of the most recent international guidelines for groin hernia managemen
Environmental mineralogy in the mining area of Montevecchio Ponente (SW Sardinia)
The Montevecchio mining area (Arbus – Guspini, Sardinia SW) has been exploited for centuries, for the
extraction of lead and zinc minerals.
The following work focuses on the study and characterization of the sources and contaminants present in
the “Cantieri Sanna” from the area of Montevecchio Ponente.
There is a large amount of mining residues in the area downstream of the washing plants, affected by
important erosion phenomena, which involve a solid transport of contaminants in solution.
These mineral residues were characterized by diffractometric (XRD) and chemical analysis (ICP-MS), after
their solubilization. The whitish biomineral patinas present along the Rio Roia Cani were also analyzed by
means of diffractometric analysis and a scanning electron microscope (SEM).
From the analysis carried out, the presence of secondary phases emerged, such as: epsomite, glaucocerinite,
goethite, hydroxyapatite, minium, nantokite, plumbojarosite and zincite, indicating a remarkable reactivity
of the tailings with atmospheric agents; these results made it possible to identify tailings as a source of
contamination. Furthermore, the presence of sub-economic contents of rare earths elements (REE), more
particularly of light rare earths elements (LREE), and of Al, Fe, Pb and Zn emerged.
Biomineralization occurs in the area was found in the streambed of rio Roja Cani; it appears like that which
forms in the bed of the rio Naracauli, described in detail in Medas et al. (2014).
SEM-EDS analysis confirm that biomineralization is mediated by bacterial activity, due to the filamentous
and tubular structures present in biofilms; furthermore, the presence of zinc and oxygen emerges from the
compositional maps, confirming that the biomineralization is composed of hydrozincite, as revealed by the
XRD analysis.
We argued that this biomineralization rules natural attenuation of zinc as already found in rio Naracauli

Can plasma levels of N-terminal pro-brain natriuretic peptide be useful in predicting the risk of developing chronic pulmonary hypertension in patients with pulmonary embolism?
Periprosthetic femoral fractures: Risk factors and current options to treatment
The incidence and complexity of the femoral fracture around a previously implanted prosthetic component has been increasing over the last ten years, and treatment can be complex, expensive and associated with an increased risk of local and systemic complications. The surgical treatment options for periprosthetic fractures include open reduction and internal fixation of bone or revision arthroplasty. This review focuses on the current surgical techniques and the pharmacological therapy to provide biological support for the enhancement of bone healing
