VIRTUS is the first United Kingdom (UK) military personal armour system to provide components that are capable of protecting the whole face from low velocity ballistic projectiles. Protection is modular, using a helmet worn with ballistic eyewear, a visor, and a mandibular guard. When all four components are worn together the face is completely covered, but the heat, discomfort, and weight may not be optimal in all types of combat. We organized a Delphi consensus group analysis with 29 military consultant surgeons from the UK, United States, Canada, Australia, and New Zealand to identify a potential hierarchy of functional facial units in order of importance that require protection. We identified the causes of those facial injuries that are hardest to reconstruct, and the most effective combinations of facial protection. Protection is required from both penetrating projectiles and burns. There was strong consensus that blunt injury to the facial skeleton was currently not a military priority. Functional units that should be prioritised are eyes and eyelids, followed consecutively by the nose, lips, and ears. Twenty-nine respondents felt that the visor was more important than the mandibular guard if only one piece was to be worn. Essential cover of the brain and eyes is achieved from all directions using a combination of helmet and visor. Nasal cover currently requires the mandibular guard unless the visor can be modified to cover it as well. Any such prototype would need extensive ergonomics and assessment of integration, as any changes would have to be acceptable to the people who wear them in the long term.

The purpose of this review was to determine if postoperative sequelae (facial swelling, trismus, pain) and neurological complications are reduced when mandibular third molars are surgically extracted using a piezoelectric device for osteotomy compared with conventional rotary burs, and to determine if there is a difference in operating time between the two techniques. Clinical trials were identified through a search (April 2015) on the PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL) and Google Scholar databases. Studies were assessed by study type, characteristics of participants, sample size, surgical technique, cointerventions, outcomes, risk of bias, and findings. We calculated a Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) rating of confidence in the effect estimates. We identified 2515 citations and found 15 eligible clinical trials. Patients who had osteotomies with the piezoelectric device had less facial swelling (standard mean difference -1.15; 95% CI -2.02 to -0.27; p<0.0001), trismus (greater maximum mouth opening, standard mean difference 0.78; 95% CI 0.56 to 1.00; p=0.33) and pain (standard mean difference -0.84; 95% CI -1.55 to -0.13; p<0.0001) at day 1, less facial swelling at day 7 (standard mean difference -0.98; 95% CI -1.52 to -0.44; p=0.05), and a reduced risk of neurological complications (odds ratio (OR) 0.28; 95% CI 0.09 to 0.89; p=0.79). Trismus at day 7 and pain at day 5 did not differ significantly between the two methods. Operating time was longer with the piezoelectric device (standard mean difference 0.83; 95% CI 0.57 to 1.09; p=0.001). The confidence in the effect estimates was low or very low across all outcomes. The findings raise the possibility of an improved clinical healing response to osteotomy with the piezoelectric device compared with one performed with conventional rotary burs for surgical extractions of mandibular third molars.

A Rare Case Report of Thoracic Ectopia Cordis: An Obstetrician’s Point of View in Multidisciplinary Approach

Ectopia cordis is a rare congenital anomaly associated with the heart positioned outside of the thoracic cavity either partially or completely. It can be associated with other congenital abnormalities. Overall, the prognosis for infants with ectopia cordis is very poor but depends greatly on the type and severity of ectopia cordis and intracardiac and associated malformations. We present one case of a fetus with prenatally diagnosed thoracic ectopia cordis with intracardiac defects and omphalocele, all the abnormalities seen in pentalogy of Cantrell except a diaphragmatic defect. Considering poor prognosis for fetus, conservative management of prenatal care has been chosen. At the 42nd gestational week, during the active stage of labor, due to fetal distress, cesarean section was performed at a tertiary level hospital. The condition of the infant was impairing rapidly and the newborn succumbed within 24 hours. We discuss the perinatal care concerning this rare anomaly.

Lack of mutation of DICER1 and FOXL2 genes in microcystic stromal tumor of the ovary

Abstract

Microcystic stromal tumors (MCST), first described in 2009 by Irving et al., are rare ovarian neoplasms. The entity was introduced into the 2014 WHO classification of tumors of female reproductive organs in the group of sex cord-stromal tumors, which is rather heterogeneous. We studied three cases of ovarian tumor with the characteristic morphological features and immunohistochemical marker profiles of MCST. The three tumors showed micro, and macrocystic patterns with solid areas, and were composed of small round to spindle-shaped cells, without atypia. The tumors diffusely and strongly expressed CD10, FOXL2, and nuclear β-catenin, but without immmunoreactivity for hormone receptors, calretinin, or inhibin. Genome analyses showed no somatic mutation of exon 1 of the FOXL2 gene and of exons 24 and 25 of DICER1 gene, the latter not having been reported previously. The patients are well, without evidence of tumor progression 1 to 10 years after diagnosis.

The absence of FOXL2 and DICER1 gene mutation, along with strong FOXL2 immunoreactivity provides additional evidence to place MCST within pure gonadal stromal rather than sex cord ovarian tumors.
