Once considered an uncommon complication, its diagnosis has increased due to increased attention and advances in medical technology. Common symptoms of the syrinx are a sensory loss of the dissociated type with pain and temperature loss and the preservation of fine touch and vibratory sensation. Eventually, a deterioration of motor function with muscle wasting may occur. CASE PRESENTATION We present the case of a 36-year-old woman who sustained a sport accident in 1996, resulting in AIS A, T7 paraplegia. She underwent a magnetic resonance imaging (MRI) examination because of neck and left shoulder pain that resolved after a short anti-inflammatory treatment. The MRI showed a large cavity involving the cord beneath T6 and the medulla. Septations were present at both the spinal cord and medulla levels. With regard to vertebral status, the MRI showed the presence of severe kyphosis at the fracture level together with spinal cord compression. The neurological examination was normal except for the pre-existing paraplegia and of a slight heat and pain sensation deficit in the C8 dermatome. DISCUSSION We discuss the need of regular follow-up examinations as even large syrines with involvement of the brainstem may be asymptomatic. We also discuss the possible pathogenetic factors including the type of treatment of the vertebral lesion.The intrinsic apoptotic pathway is controlled by the BCL-2 family of proteins, which exhibit either a pro-death or pro-survival function. Gene knockout studies revealed that different pro-survival BCL-2 proteins are critical for the survival of distinct cell types, although overlapping functions amongst such proteins have also been identified. In the process of studying mice lacking single alleles of Mcl-1 (Mcl-1+/-), Bcl-2 (Bcl-2+/-), or both in combination (Mcl-1+/-Bcl-2+/-), we observed that Mcl-1+/-Bcl-2+/- mice weighed less when compared with their wild-type littermates as they aged. Body composition analysis demonstrated that while fat mass was similar to wild-type controls, lean mass was significantly reduced in Mcl-1+/-, Bcl-2+/-, and, most strikingly in Mcl-1+/-Bcl-2+/- mice. The weights of several tissues including the heart, tibialis anterior, and kidney were likewise reduced in Mcl-1+/-Bcl-2+/- mice. When lean mass and specific tissue weights were expressed relative to body weight, these differences were no longer significant, indicating that that Mcl-1+/-Bcl-2+/- mice, and to a lesser extent Mcl-1+/- and Bcl-2+/- mice, are smaller than their wild-type counterparts. Consistently, the anal-naso length was reduced in Mcl-1+/-Bcl-2+/- mice. While minor reductions in size were observed in female Mcl-1+/-Bcl-2+/- mice, these effects were most prominent in males. Notably, Mcl-1+/-Bcl-2+/- males had markedly smaller testes even after accounting for differences in body weight. Collectively, these data reveal that combined loss of a single allele of Mcl-1 and Bcl-2, while not overtly impairing organismal development, leads to a reduction in animal size.Deleted in azoospermia-like (DAZL) is an RNA-binding protein critical for gamete development. In full-grown oocytes, the DAZL protein increases 4-fold during reentry into the meiotic cell cycle. Here, we have investigated the functional significance of this accumulation at a genome-wide level. Depletion of DAZL causes a block in maturation and widespread disruption in the pattern of ribosome loading on maternal transcripts. In addition to decreased translation, DAZL depletion also causes translational activation of a distinct subset of mRNAs both in quiescent and maturing oocytes, a function recapitulated with YFP-3'UTR reporters. DAZL binds to mRNAs whose translation is both repressed and activated during maturation. Injection of recombinant DAZL protein in DAZL-depleted oocytes rescues the translation and maturation to MII. Mutagenesis of putative DAZL-binding sites in these mRNAs mimics the effect of DAZL depletion. These findings demonstrate that DAZL regulates translation of maternal mRNAs, functioning both as the translational repressor and activator during oocyte maturation.Stent graft devices for the treatment of abdominal aortic aneurysms (AAAs) are being increasingly used worldwide. Yet, during modelling and optimization of these devices, as well as in clinical practice, vascular sections are idealized, possibly compromising the effectiveness of the intervention. In this study, we challenge the commonly used approximation of the circular cross-section of the aorta and identify the implications of this approximation to the mechanical assessment of stent grafts. Using computed tomography angiography (CTA) data from 258 AAA patients, the lumen of the aneurysmal neck was analysed. The cross-section of the aortic neck was found to be an independent variable, uncorrelated to other geometrical aspects of the region, and its shape was non-circular reaching elliptical ratios as low as 0.77. These results were used to design a finite element analysis (FEA) study for the assessment of a ring stent bundle deployed under a variety of aortic cross-sections. Results showed that the most common clinical approximations of the vascular cross-section can be a source of significant error when calculating the maximum stent strains (underestimated by up to 69%) and radial forces (overestimated by up to 13%). Nevertheless, a less frequently used average approximation was shown to yield satisfactory results (5% and 2% of divergence respectively).We applied continuous intraoperative neuromonitoring (CIONM) during video-assisted thoracoscopic surgery (VATS) lobectomy for left lung cancer and evaluated its safety and usefulness. An electrode was attached to a double-lumen tube, and placed at vocal cord level to detect the EMG signal evoked by vocal cord movement. Before 4 L lymph node dissection, an automatic periodic stimulation device was applied to the vagus nerve to stimulate vagus nerve continuously. Surgery was suspended if the amplitude decreased lower than the threshold and was resumed when the amplitude recovered. Ten patients (6 male, 4 female) were enrolled. FLT3-IN-3 CIONM was successfully performed in all patients without technical failure, and there was no hemodynamic instability. Amplitude decreased below the threshold in four patients. One patient did not recover amplitude and experienced transient vocal cord palsy. In the three other patients, the amplitude recovered above the threshold and no vocal cord palsy occurred. The six patients who did not exhibit amplitude decrease experienced no vocal cord palsy.
