Radiofrequency Echographic Multi Spectrometry (REMS) Technology for Bone Health Status Evaluation in Kidney Transplant Recipients.

: A significant loss in bone density and strength occurs during the post-renal-transplant period with higher susceptibility to fracture. The study aims to compare the performance of the Radiofrequency Echographic Multi Spectrometry (REMS) in the bone mineral density assessment with the conventional dual-energy X-ray absorptiometry (DXA) in a cohort of kidney transplant recipients (KTR). : A cohort of 40 patients underwent both DXA and REMS examinations on the lumbar spine and/or proximal femur.

Arterial stiffness and cardiovascular risk in patients with nephrolithiasis: a 10-year prospective study.

Background: Nephrolithiasis is frequently associated with cardiovascular diseases. These conditions present common risk factors: systemic inflammation that promotes oxidative stress leading to arterial wall stiffening may also play a role in plaque formation predisposing to nephrolithiasis.

Objectives: The aim of this study was to evaluate arterial stiffness indices at baseline and after a 10-year follow-up, in patients with nephrolithiasis compared with patients without.

Could synovial fluid be a useful substrate for the forensic analysis of diatoms?

To date, synovial fluid has not been the subject of targeted analysis as a possible substrate to search for the presence of diatoms in the forensic context of drowning. However, its unique characteristics of production and isolation from the external environment could make it suitable for this purpose, similar to what has already been demonstrated in the literature for vitreous humor. By considering this, synovial fluid was analyzed in a specific case that came to our attention, where the coexisting signs of polytrauma and drowning were documented during autopsy, demonstrating a period of vitality during immersion.

Methods: For this purpose we used two different colorimetric techniques known in the literature, namely 0.2% sodium rhodizonate (Na-R-Ba 0.

Long-Term Bone Mineral Density Changes in Kidney Transplant Recipients Treated with Denosumab: A Retrospective Study with Nonequivalent Control Group.

Data on the effectiveness of denosumab on osteoporosis after kidney transplantation are limited. We investigated the long-term bone mineral density (BMD) changes in kidney transplant recipients (KTRs) treated with denosumab compared to untreated KTRs. We enrolled KTRs treated with denosumab 60 mg/6 months for 4 years.

Forensic pilot application of rehydrating solutions on human cadaveric skin: what are the effects on hemorrhagic infiltrates?

The microscopic evaluation of hemorrhagic infiltrates is crucial in forensic diagnostics, but it proves challenging in corificated and mummified cadavers. In these cases, pre-treatment with rehydrating solutions is recommended, although their effects on the hemorrhagic infiltrate are not well understood. In this pilot study, we microscopically investigated the effect of two different rehydrating solutions-Sandison's solution and fabric softener-on well-preserved human cadaveric skin samples taken from areas affected by an ecchymotic lesion, comparing them with direct fixation in formalin.

Association analysis of 10 candidate genes causing Mendelian calcium nephrolithiasis in the INCIPE study: a South European general population cohort.

Background: Idiopathic calcium nephrolithiasis (ICN) is a common condition with a complex phenotype influenced by both environmental and genetic factors. In our study we investigated the association of allelic variants with the history of nephrolithiasis.

Methods: We genotyped and selected 10 candidate genes potentially related to ICN from 3046 subjects participating in the INCIPE survey cohort (Initiative on Nephropathy, of relevance to public health, which is Chronic, possibly in its Initial stages, and carries a Potential risk of major clinical End-points), a study enrolling subjects from the general population in the Veneto region in Italy.

Utility and diagnostic value of postmortem microbiology associated with histology for forensic purposes.

Nowadays, the diagnostic value of postmortem microbiological investigations is still a debated topic, but postmortem microbiology (PMM) remains a discipline with great forensic potential. To evaluate the usefulness and diagnostic-forensic value of postmortem microbiological cultures, it has been conducted a study on cadaveric material sampled during autopsy aiming to identify the correct cause of death. The study analyzed 45 cadavers subjected to judicial autopsy, divided into two groups based on the presence or absence of external or internal macroscopic autopsy signs suggesting infectious pathology.

Elastic fiber degradation as a possible indicator for PMI estimation on mummified and corified skin: a pilot study.

Mummified and corified bodies are particularly complex scenarios to investigate, starting from identifying the post-mortem interval (PMI), even more so in indoor environments. In these bodies, the skin has the peculiar feature to resist for a long time. Among its components, there are elastic fibers, which are characterized by intrinsic resistance to post-mortem degenerative phenomena.

Radiofrequency echographic multi-spectrometry and DXA for the evaluation of bone mineral density in a peritoneal dialysis setting.

Background: The aim of this real-life cross-sectional explorative study was to compare radiofrequency echographic multi-spectrometry (REMS) with dual-energy X-rays absorptiometry (DXA) in the BMD assessment of patients receiving peritoneal dialysis (PD). Furthermore, we investigated the relationship between lumbar aortic calcifications (AOCs) and the DXA lumbar measurements.

Methods: Consecutive patients referring to the PD clinic of our hospital were included.

Outcomes in AB0 Incompatible Living Donor Kidney Transplantation: A Case - Control Study.

Background: Patients waiting for a kidney transplant by far exceed available organs. AB0 incompatible living donor kidney transplantation (AB0i LDKT) represents an additional therapeutic strategy, but with higher risk for complications. We aimed at evaluating outcomes of AB0i LDKTs compared to compatible (AB0c) controls at our Institution.

Postmortem Diagnosis of Invasive Disseminated Aspergillosis After Tongue Piercing.

Severe fungal infections caused by highly invasive fungi such as Aspergillus are not easy to diagnose and often have a poor prognosis. In these cases, the nonspecific symptoms may make clinical diagnosis challenging, and consequently, the autopsy and postmortem histological investigations acquire a crucial role. We report the case of a young man in good health who died of septic shock 3 weeks after having had a tongue piercing.

Technical note: A comparison between rehydrating solutions in the pretreatment of mummified and corified skin for forensic microscopic examination.

Microscopic examination of mummified or corified skin may be of extreme importance for forensic purposes. However, standard histological samples in these cases are low-end, and preparation is burdened by several problems and so are diagnostic results: an improvement of these types of specimens is therefore advantageous. This study aims to identify the best performing rehydration solution among a fabric softener, a body lotion, and Sandison's rehydrating solution.

Use of cadaveric vitreous humor as an innovative substrate for diatoms research and forensic diagnosis of drowning.

The search for diatoms is the test that most of all may contribute to the forensic diagnosis of drowning. Diatoms can be extracted through different methods, which are all complex and long. In this preliminary study, we assessed human vitreous humor as an innovative substrate on which to research diatoms.

Analysis of the corrosive effects of hydrochloric acid (HCl) on human bone: Preliminary microscopic study and observations for forensic purposes.

The destruction of a corpse in caustic acid can cause complex forensic scenarios to deal with. Furthermore, the literature on the subject is poor, having been the few studies carried out only on animal bones. We carried out an experimental analysis on human cranial, ribs, vertebrae, and femur bone fragments.

Histotopography of haemorrhagic infiltration in the hanging cutaneous furrow: Where to look for haemorrhagic infiltration in hanging.

The forensic evidence of hanging is based on the autopsy demonstration of the traces left by the noose or the ligature on the neck, as well as on the histological assessment of the hanging mark vitality. However, the specific topography of haemorrhagic infiltration in the context of the cervical damaged tissues involved in hanging is not known. We carried out an extensive microscopic examination to identify if haemorrhagic infiltration in hanging appeared in specific topographic locations that could have been considered as elective.

Paradoxal dyeing affinity's inversion of the connective tissue at Goldner's Masson trichrome staining as a peculiar characteristic of compressed and exsiccated cadaveric skin.

The microscopic examination of a hanging cutaneous furrow, stained with Goldner's Masson trichrome staining, highlighted an abnormal dyeing inversion affinity of the connective tissue - red instead of green - located in the region of maximal cutaneous compression and exsiccation. To identify if this different stainability could be considered as an intrinsic characteristic of all biological tissues compressed and exsiccated, we have assessed different cadaveric skin samples that underwent traumatic detrimental phenomena that can produce such effects. We collected skin fragments from 24 corpses deceased because of gunshot injuries, electrocution, hanging, and heat-induced lesions, sampling the areas directly involved, as well as skin specimens to use as a control.

Lethal extracranial hemorrhage due to intracranial clivalchordoma: An autopsy case.

We present a case of a 48-year-old man's unexpected death affected by a relapsed clivalchordoma. After partial excision surgery of the neoplasm, he manifested 5 days later, in conditions of well-being, a sudden lethal extracranial hemorrhage from nose and mouth. The autopsy examination and the subsequent histological investigations did not allow us to clarify the exact origin of the bleeding.

Look before washing and cleaning: A caveat to pathologists and anthropologists.

Partially or totally skeletonized bodies are undoubtedly the most challenging scenario to deal with for forensic pathologists and anthropologists. Indeed, in such cases, being able to figure out the cause and manner of death is often tricky. Human remains require to be washed and cleaned before a thorough assessment of any signs of trauma.

The frequently dismissed importance of properly sampling skin bruises.

The correct interpretation of skin lesions is a crucial issue in forensic medicine. Many macroscopic and microscopic vital reaction markers and molecules have been studied in the past years in order to estimate the timing of injuries. However, literature lacks information regarding how to perform sampling to obtain a more reliable and accurate response.
