Fibrin associated large B-cell lymphoma accidentally identified in a breast implant capsule: a molecular report of a rare entity.

Breast implant-associated (BIA) lymphoma is a rare malignancy, typically originating from T-cells; however, few cases of diffuse large B-cell lymphoma (LBCL) have been recently described. These cases share major features: Epstein-Barr virus positivity and a favorable prognosis with surgical intervention alone, hinting at a potential link to fibrin-associated LBCL (FA-LBCL). This study presents the first case of BIA-FA-LBCL in Italy and one of the few assessed from a molecular standpoint so far.

Light chain deposition disease: pathogenesis, clinical characteristics and treatment strategies.

Light chain deposition disease (LCDD) is a rare hematologic disorder characterized by the deposition of non-amyloid monoclonal light chains in several organs. Together with renal impairment is being the primary morbidity associated with this disease. Due to its rarity, randomized clinical trials lack to explore treatment strategies and there are no approved or universally accepted standard of care treatment options.

Bone turnover profile and muscular status in major orthopaedic surgery: a case series.

BACKGROUND Sarcopenia refers to a chronic loss of skeletal muscle mass, often associated with hypovitaminosis D and advanced age, which involves a greater risk of falls and fractures. The association of sarcopenia and osteoporosis defines osteo-sarcopenia. In this work, the authors analyzed the osteometabolic profile and the loco-regional muscular state of patients undergoing major orthopedic surgery, in order to define the incidence of district osteosarcopenic states, linked to a condition of disuse.

A Multisystem Mitochondrial Disease Caused by a Novel MT-TL1 mtDNA Variant: A Case Report.

Background: Mitochondrial tRNA (MTT) genes are hotspot for mitochondrial DNA mutation and are responsible of half mitochondrial disease. MTT mutations are associated with a broad spectrum of phenotype often with complex multisystem involvement and complex genotype-phenotype correlations. MT-TL1 mutations, among which the m.

A new technique of ultrasound guided percutaneous renal biopsy by perforated probe and perpendicular needle trajectory.

The percutaneous biopsy of native kidneys according to the classical methodology is performed under real time ultrasound guidance with the needle introduction along a trajectory of about 30°, aimed to the lower pole of the kidney. Recently, a variant of the classical technique has been introduced by which a perforated ultrasound probe is used to guide the needle along a perpendicular trajectory to the terminal section of the lower kidney pole where the front and back margins of the cortical kidney tissue join each other without renal sinus interposition so to offer to the needle a 3-4 cm thick cortical tissue front which allows to obtain a cortical tissue sample suitable for histological examination even with a single needle pass, while at the same time limiting the possibility of damaging the smaller kidney calices of the lower group whose lesion causes hematuria. In this paper, we present a large survey (50 patients) to compare to data from the literature obtained by using similar needle gauge and with a similar follow-up period after biopsy.

[A variant of the classic technique of ultrasound guided percutaneous renal biopsy: the perpendicular entry by longitudinal viewing planes with a perforated probe].

The percutaneous biopsy of native kidneys according to the classic methodology, takes place with the introduction of the needle and its guide with ultrasound sagittal viewing planes, with a 30-degree angle, up to the lower pole of the kidney. Since the longitudinal axis of the kidneys converges towards the spine with a sharp angle, we observed that starting from a longitudinal scan of the kidney (conducted along the posterior axillary line with the patient prone) you can drive the needle by a perforated probe through a shorter path perpendicular to the end section of the lower pole of the kidney where the front and rear rims of the cortex bearings without the renal sinus interposed so increasing the chance to obtain, even with a single pass, a good sample of cortical tissue while limiting the possibility to damage the lower chalices that may cause hematuria. We biopsied in that manner 26 patients and we compared the data with those reported in the literature performed with the same needle gauge and post-biopsy monitoring period.
