Purpose of review: After it was first described in 1939, medullary sponge kidney (MSK) received relatively little attention. This was because it was believed to have a low prevalence and because it was considered a benign condition. Studies in recent years have been changing these convictions however, hence the present review. Recent findings: Insight has been obtained on the genetic basis of this disease, supporting the hypothesis that MSK is due to a disruption at the 'ureteric bud-metanephric mesenchyme' interface. This explains why so many tubular defects coexist in this disease, and particularly a distal tubular acidification defect of which the highly prevalent metabolic bone disease is one very important consequence. In addition to the typical clinical phenotype of recurrent stone disease, other clinical profiles have now been recognized, that is, an indolent, almost asymptomatic MSK, and a rare form characterized by intractable, excruciating pain. Summary: Findings suggest the need for a more comprehensive clinical characterization of MSK patients. The genetic grounds for the condition warrant further investigation, and reliable methods are needed to diagnose MSK. © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins. Source

Heparanase is the unique and specific functional endoglycosidase capable of cleaving heparan sulfate (HS) chains. It exerts its enzymatic activity catalyzing the cleavage of the β (1, 4)-glycosidic bond between glucuronic acid and glucosamine residue. HS cleavage results in remodelling of the extracellular matrix as well as in regulating the release of many HS-linked molecules such as growth factors, cytokines and enzymes involved in inflammation, wound healing and tumour invasion. A pro-metastatic and pro-angiogenic role for this enzyme has been widely demonstrated in many primary human tumours since high levels of heparanase correlate with lymph node and distant metastasis, elevated micro vessel density and reduced survival of cancer patients. Recently, data have been reported that heparanase regulates heparan sulfate proteoglycan syndecan-1 and promotes its shedding from the cell surface. Shed syndecan-1 in turn controls tumour growth, metastasis and neo-angiogenesis mainly by promoting growth-factor signaling in the tumour milieu. Considering that, once inactivated, there are no other molecules capable of performing the same function, it is evident how this enzyme may be an effective and attractive drug target. Several heparanase inhibitors have been developed and some of them have undergone clinical trials showing efficacy against tumours. In this mini-review we will discuss current knowledge of heparanase involvement in cancer as well as its targeted inhibition as a promising therapeutic option in tumour treatment. © 2014 Bentham Science Publishers.

Oligodontia may compromise the harmonious development of the masticatory system. The quantity and quality of agenesis determines the type of approach and the complexity of rehabilitative therapy. We present a case of a patient affected by oligodontia and maxillo-mandibular skeletal alterations, corrected by orthodontic and orthognatic surgical treatment, assisted by prosthetic-presurgical rehabilitation of the lower arch. After surgery the occlusion was finally restored by a definitive prosthesis modeled on the presurgical one and supported by the same residual dental elements. Photographic and cephalometric analysis have shown the stability of the results at 20 years follow-up. The case presented shows that the final prosthesis on the residual teeth in patients affected by oligodontia may represent a possible alternative to implanto-prosthetic rehabilitation, presenting lower cost and requiring less time for definitive occlusal rehabilitation.

Patients with primary and secondary chronic glomerular diseases are at significant risk for progression to end-stage renal disease. Unfortunately the treatment armamentarium is relatively limited in terms both of available agents and of specificity. Experimental evidence supports the idea that heparin-derived agents and glycosaminoglycans (GAGs) favorably affect primary and secondary renal diseases. While a number of clinical exploratory studies have addressed the effect of these agents in microalbuminuric and macroalbuminuric diabetic patients, very few have investigated their activity in nondiabetic renal conditions. This paper will review the experimental and clinical evidence on the use of GAGs in renal disease other than diabetic nephropathy, following the reports of experimental findings supporting their use and the possible mechanisms involved: anticoagulant and antiproliferative activity, effect on growth factors (PDGF, FGF2 and TGF-β1), inhibition of heparanase, macrophage renal infiltration and of the renin-angiotensin system, and decrease in proteinuria. Targeting these pathogenic loops with GAG treatment might be revealed to be very rewarding from a clinical point of view. Prospective randomized controlled trials with large case populations and definite entry criteria are clearly indicated. © 2010 Società Italiana di Nefrologia. Source

There are few studies on maxillomandibular skeletal alterations. Twenty-one patients with unilateral coronal craniosynostosis were analysed and compared with controls. Landmarks analysed were: sella-nasion-point A and B angles, point A-nasion-point B angle, interincisal angle, angle of superior incisor axis on the sella-nasion plane, lower incisor to mandibular plane angle, Frankfort mandibular plane angle, zygomatic-frontal suture (Z), point on the most concave part of pyramidal apophysis of the upper maxilla (Mx), antegonial incisure (AG), upper (UMT) and lower (LMT) molar teeth. Differences were significant for class II dentoskeletal occlusion (p<0.0001), mandibular hyperdivergence (p<0.0001), lingualization of superior incisor (p<0.005), deviation of inferior interincisal contralateral line to the synostosis (p<0.0001) in the plagiocephalic population. Compared with contralateral counterpoints, Z (p<0.05), Mx (p<0.005) and UMT (p<0.0005) on the affected side were closer to the midline; AG (p<0.0005) and LMT (p<0.05) were further from it. On the frontal plane, Z, Mx, UMT, LMT and AG on the affected side were higher. Vertical and transversal contraction of the jaw of the synostotic side and laterodeviation of the mandibular interincisal line of the contralateral synostotic were clear. The altered position of the glenoid cavity, anteriorized in unilateral coronal craniosynostosis, could be the cause of mandibular dentoskeletal asymmetry.
