BACKGROUND: Microvascular decompression for patients with trigeminal neuralgia (TGN) is widely accepted as one of the modalities of treatment. The standard approach has been retrosigmoid suboccipital craniotomy with placement of a Teflon pledget to cushion the trigeminal nerve from the offending artery, or cauterize and divide the offending vein(s). However, in cases of severe compression caused by a large artery, the standard decompression technique may not be effective. OBJECTIVE: To describe a unique technique of vasculopexy of the ectatic basilar artery to the tentorium in a patient with TGN attributed to a severely ectatic and tortuous basilar artery...

Intrathoracic common carotid artery bifurcations are an anatomic anomaly with such rarity that only six cases have been reported to date. The true incidence of and preferred treatment options for a diseased intrathoracic common carotid artery bifurcation or internal carotid artery (ICA) have not been clearly described. This case report describes a 72-year-old man who experienced a postoperative right hemispheric stoke after an aortic valve replacement, radiofrequency maze procedure, and left atrial appendage clip...

Posterior nutcracker syndrome occurs when a retroaortic left renal vein becomes compressed between the abdominal aorta and the lumbar spine. Although open surgical approaches remain the treatment of choice, endovascular stenting has been used successfully. We describe a case of a 28-year-old man who presented with microscopic hematuria, left-sided flank pain, and testicular swelling. Computed tomography findings were consistent with posterior nutcracker syndrome. He underwent a novel hybrid operation that included left renal vein transposition followed by endovascular stenting...

We present a novel surgical technique for lower limb revascularization after resection of an aneurysm of the persistent sciatic artery that had led to recurrent peripheral embolization and severe ischemia. The superficial femoral artery in this patient was hypoplastic, and the sciatic artery continued into the popliteal artery as the source of blood supply to the lower leg. For revascularization, we used the distally pedicled healthy two-thirds of the persistent sciatic artery, transposed it from its posterior position to a nearly anatomic anteromedial position, and anastomosed it to the proximal superficial femoral artery...

Over the past 30 years, advances in antineoplastic treatment led to a significant increase in the survival of patients with childhood cancer. In Europe and the United States, 82% of children, adolescents, and young adults survive 5 years from the cancer diagnosis and the majority achieves long-term survival into adulthood. The impact of cancer therapy on fertility is related to the age of the patient and to the duration, dose/intensity, and type of treatment. Exposure to chemotherapy or to radiation to gonads or pituitary brings long-term complications of cancer-directed therapies that include effects on reproductive capacity...

BACKGROUND: The resection of large soft-tissue sarcoma requires reconstruction with free flaps. The choice of recipient vessels is crucial for the success of surgery. PATIENTS: We report four cases with large soft-tissue sarcomas with complex anatomical relationships: two tumors of the thigh surrounding the femoral neurovascular structures and two tumors of the abdomen with infiltration of the thorax and the abdomen. All cases received multimodal interdisciplinary treatment...

Background: Habitual patellar dislocation is a rare condition affecting children. The growth plates are open in children and any surgical intervention should take that in to consideration. We are describing a modified four in one technique for habitual patellar dislocation, which is a soft tissue procedure without the use of any implant. Method: In this study we included 6 children (4 females and 2 males) with open growth plates, which were diagnosed with habitual patellar dislocation...

Primate-specific Alu short interspersed elements (SINEs) as well as rodent-specific B and ID (B/ID) SINEs can promote Staufen-mediated decay (SMD) when present in mRNA 3'-untranslated regions (3'-UTRs). The transposable nature of SINEs, their presence in long noncoding RNAs, their interactions with Staufen, and their rapid divergence in different evolutionary lineages suggest they could have generated substantial modification of posttranscriptional gene-control networks during mammalian evolution. Some of the variation in SMD regulation produced by SINE insertion might have had a similar regulatory effect in separate mammalian lineages, leading to parallel evolution of the Staufen network by independent expansion of lineage-specific SINEs...

Transposition of great arteries (TGA) can be associated with left ventricle outflow tract (LVOT) obstruction. In the presence of ventricular septal defect (VSD), septal leaflet of tricuspid valve may prolapse through perimembranous VSD or rarely tricuspid valve tissue may override to produce LVOT obstruction. Occasionally, this may be mistaken for vegetation due to associated pulmonary valve endocarditis. We report a case of d-TGA with presumptive pulmonary valve endocarditis and LVOT obstruction that was found to be due to tricuspid valve straddling on transesophageal echocardiography, resulting in change in the surgical plan and thus avoiding catastrophe...

PURPOSE: The "reading man" flap (RMF), a double advancement transposition cutaneous flap named for its appearance, has been described in the reconstruction of various circular skin defects, particularly in the malar region. We describe two cases where this flap was used to reconstruct the lower eyelid/periorbital region. METHODS: Two oculoplastic patients with lower eyelid basal cell carcinomas underwent Mohs micrographic excision resulting in a large skin defects...

Objectives: The aim of this study was to evaluate different anatomical variants of the anterior loop of the inferior alveolar nerve (IAN) via cone-beam computed tomography (CBCT). Materials and Methods: CBCT images of 71 patients (36 males and 35 females) were evaluated. We used the classification described by Solar for IAN evaluation. In this classification, three different types of IAN loops were introduced prior to emerging from the mental foramen. We classified patients according to this system and introduced a new, fourth type...

REVIEW
Savannah J Klein, Rachel J O'Neill
Although it was nearly 70 years ago when transposable elements (TEs) were first discovered "jumping" from one genomic location to another, TEs are now recognized as contributors to genomic innovations as well as genome instability across a wide variety of species. In this review, we illustrate the ways in which active TEs, specifically retroelements, can create novel chromosome rearrangements and impact gene expression, leading to disease in some cases and species-specific diversity in others. We explore the ways in which eukaryotic genomes have evolved defense mechanisms to temper TE activity and the ways in which TEs continue to influence genome structure despite being rendered transpositionally inactive...

The increasing survival in the adulthood of patients with congenital heart disease (CHD) has changed the epidemiology of adult CHD (ACHD) patients and has led to an increment in hospitalization rates due to heart failure (HF). ACHD patients hospitalized for HF have a five-fold higher risk of death HF than those compensated. HF occurs predominantly in patients with tetralogy of Fallot, single ventricles, and after the Mustard operation for transposition of the great arteries. Diagnostic strategies applied in acquired HF patients are usually used to evaluate ACHD patients, but sometimes this can postpone the identification of HF that can become manifest with unusual and peculiar signs or symptoms...

The reduction of effluents deriving from analytical control is a serious concern in the nuclear industry, for both production and R & D units. In this work we report an alternative methodology for the standard UV-Vis absorbance analyses for acti-nides concentration monitoring along the PUREX (Plutonium Uranium Redox Extraction) process. This methodology, based on Photonic Lab-on-a-chip (PhLoC) technology, enables drastic sampling reduction down to a few microliters, and simulta-neously allows to track concentrations over several orders of magnitude while maintaining a detection linearity range...

Congenitally corrected transposition of the great arteries (ccTGA) can occur in isolation, or in combination with other structural cardiac anomalies, most commonly ventricular septal defect, pulmonary stenosis and tricuspid valve disease. Clinical recognition can be challenging, so echocardiography is often the means by which definitive diagnosis is made. The tricuspid valve and right ventricle are on the systemic arterial side of the ccTGA circulation, and are therefore subject to progressive functional deterioration...

Objective: Strabismus with diplopia is the main orbital complication of functional endoscopic sinus surgery (FESS). This study was to analyze clinical findings, treatment and outcomes of such cases. Methods: Retrospective case series. Twenty-three cases were divided into 3 groups based on the disease severity: group A, partial transection of the medial rectus muscle, group B, complete transection of the medical rectus, group C, transection of the medial rectus combined with the other orbital injuries. Complete ophthalmology examinations, including eye alignment, eye motility, force duction test, force generation test, general eye exam, and medical imaging (orbital CT or MRI), were performed for each case...

Short interspersed elements (SINEs), which are non-autonomous transposable elements, require the transposition machinery of long interspersed elements (LINEs) to mobilize. SINEs are composed of two or more independently originating parts. The 5' region is called the "head" and is derived mainly from small RNAs, and the 3' region ("tail") originates from the 3' region of LINEs and is responsible for being recognized by counterpart LINE proteins. The origin of the middle "body" of SINEs is enigmatic, although significant sequence similarities among SINEs from very diverse species have been observed...

Genetic analyses of patients with transposition of the great arteries have identified rare copy number variations, suggesting that they may be significant to the aetiology of the disease. This paper reports the identification of a 16p11.2 microduplication, a variation that has yet to be reported in association with transposition of the great arteries. The 16p11.2 microduplication is associated with autism spectrum disorder and developmental delay, but with highly variable phenotypic effects. Autism and attention deficit disorders are observed more frequently in children with congenital heart disease than in the general population...
