Mandibular symphyseal distraction osteogenesis (MSDO) is an alternative strategy to correct mandibular transverse deficiencies and dental crowding. Only a limited number of practitioners have reported their clinical experience and potential complications of this procedure to widen the mandible in a large case series. This study involved retrospective analysis of 40 patients who underwent mandibular symphyseal distraction osteogenesis. Three different types of distractor were used to widen the mandible: tooth-borne in 21 patients, bone-borne in 5 patients and hybrid (both bone and tooth-borne) in 14 patients. The distraction amount ranged from 7 to 11 mm (mean 7.31 mm). While 39 patients underwent successful mandibular symphyseal distraction, there was one failure. Most of the complications were experienced in bone-borne distractors, such as breakage of the distractor rod, gingival recession, secondary infection and ptosis of the chin. In the light of these findings, it is suggested that a lingually placed tooth-borne hyrax appliance is more suitable and reliable than the other distraction devices. Further larger studies are needed in order to better evaluate the effectiveness of bone-borne or hybrid devices.

The aim of the study was to analyse the rate of complications of orbital endoimplantation in patients operated from 2002 to 2014 at the Eye Clinic of the Lithuanian University of Health Sciences and to compare it with the results in the literature. Enucleation must be performed very carefully in order to prevent any additional trauma, infection, deformation, and to create an optimal conjunctival socket. However, complications occur despite efforts and qualified surgeons. The most common complications described in the literature are thinning and cysts of the conjunctiva, a foreign body reaction, secretion, symblepharons, fornix deficiency, ptosis, permanent pain, dislocation, migration and protrusion of the implant, a primary or secondary infection, and implant extrusion. From 2002 to 2014, 128 patients underwent orbital endoimplantation surgery at the Eye Clinic. The most common complications were conjunctival erosion (five patients, or 2.9%), cysts (nine patients, or 7%), and implant extrusion (five patients, or 2.9%). The type and rate of complications were very similar to the data in the literature.

Sepsis is recognized as a life-threatening organ dysfunctional disease that is caused by dysregulated host responses to infection. Up to now, sepsis still remains a dominant cause of multiple organ dysfunction syndrome (MODS) and death among severe condition patients. Pyroptosis, originally named after the Greek words "pyro" and "ptosis" in 2001, has been defined as a specific programmed cell death characterized by release of inflammatory cytokines. During sepsis, pyroptosis is required for defense against bacterial infection because appropriate pyroptosis can minimize tissue damage. Even so, pyroptosis when overactivated can result in septic shock, MODS, or increased risk of secondary infection. Proteolytic cleavage of gasdermin D (GSDMD) by caspase-1, caspase-4, caspase-5, and caspase-11 is an essential step for the execution of pyroptosis in activated innate immune cells and endothelial cells stimulated by cytosolic lipopolysaccharide (LPS). Cleaved GSDMD also triggers NACHT, LRR, and PYD domain-containing protein (NLRP) 3-mediated activation of caspase-1 via an intrinsic pathway, while the precise mechanism underlying GSDMD-induced NLRP 3 activation remains unclear. Hence, this study provides an overview of the recent advances in the molecular mechanisms underlying pyroptosis in sepsis.
