Microvascular reconstruction of the mouth, face and jaws. Oromandibular reconstruction – free fibula flap
We present our experience with the free fibula flap used for oromandibular reconstruction; this was undertaken in 21 patients following resective surgery for malignant pathology, cytologically benign but biologically aggressive odontogenic pathology and radiation induced osteonecrosis. We also review the history, surgical anatomy, surgical assessment and potential complications that are relevant to the free fibula flap.

Comparison of Everolimus-Eluting and Sirolimus-Eluting Coronary Stents: 1-Year Outcomes from the Randomized Evaluation of Sirolimus-Eluting Versus Everolimus-Eluting Stent Trial (RESET).
CONCLUSIONS: One-year clinical and angiographic outcome after EES implantation was non-inferior to and not different from that after SES implantation in a stable coronary artery disease population with relatively less complex coronary anatomy. One-year clinical outcome after both EES- and SES-use was excellent with low rate of TLR and very low rate of stent thrombosis.

Tunicamycin Inhibits PDGF-BB-Induced Proliferation and Migration of Vascular Smooth Muscle Cells Through Induction of HO-1.
In this study, we found that pretreatment with tunicamycin (Tm), an ER stress inducer, significantly inhibited platelet-derived growth factor (PDGF)-BB-induced VSMC proliferation and migration in a dose-dependent manner without causing significant apoptosis. Tm stimulated the expression of the antioxidant gene heme oxygenase-1 (HO-1) both at the transcriptional and translational levels, while reducing phosphorylation and activation of mitogen-activated protein (MAP) kinases. The negative regulative effects of Tm were associated with a decrease in cyclins and cyclin-dependent kinases (CDKs) activation. More importantly, HO-...

Reversed intestinal malrotation with concurrent cecal carcinoma
AbstractA 57‐year‐old man was admitted with a type 2 (ulcerated with clear margin) cancer in the cecum. Contrast‐enhanced CT showed that the superior mesenteric vein was anterior to the superior mesenteric artery, and the patient was suspected of having intestinal malrotation. A laparoscopic‐assisted ileocecal resection was performed. At operation, the cecum and the transverse colon passed through the root of the mesentery behind the superior mesenteric artery with the duodenum. Therefore, this was thought to be a reversed‐type intestinal malrotation. After the operation, 3D‐CT colonography with duodenography i...

Postnatal alteration of collapsin response mediator protein 4 mRNA expression in the mouse brain.
Abstract Collapsin response mediator protein 4 (CRMP4) is a molecular marker for immature neurons but only limited information is available on the spatiotemporal gene expression changes of Crmp4 in the developing rodent. In the present study, the variation of CRMP4 mRNA expression in the mouse brain was investigated from postnatal day (PD) 0 (the day of birth) to adulthood by in situ hybridization. The hybridization signals were broadly detected on PD0 and regional changes in expression during development were noted. Expression patterns of CRMP4 mRNA were classified into the following three types: (i) signals that ...

The oblique branch trap in the harvest of the anterolateral thigh myocutaneous flap
AbstractA 67‐year‐old man with squamous cell carcinoma underwent reconstruction with a free anterolateral thigh myocutaneous flap. Unroofing the skin perforators found that the skin perforators originated from the oblique branch of the lateral circumflex femoral artery with no connections with the descending branch. Thus, the flap was harvested based on the oblique branch, leaving the descending branch in situ. Reconstruction was completed uneventfully and he had an excellent outcome at 1‐year follow‐up. The anterolateral thigh myocutaneous flap was reputed to be a technically easy flap to harvest. The perforators ...

Genomic analysis of the appearance of testicular oocytes in MRL/MpJ mice
In this study we focused on the autosomal genes and examined their relationship with this phenotype by analyzing the progeny from crosses between MRL mice and other strains. We first observed the male F1 progeny from the crosses between female A/J, C57BL/6 (B6), BALB/c, C3H/He, or DBA/2 mice and male MRL mice, and two consomic strains, male B6-YMRL and MRL-YB6. Testicular oocytes that were morphologically similar to those of MRL mice were detected in all mouse strains except BALBMRLF1; however, the incidence of testicular oocytes was significantly lower than that in MRL mice. The appearance of testicular oocytes in MR...

Two-handed endoscopic-directed vestibular nerve sectioning: case series and review of the literature.
Conclusions The endoscopic-directed approach represents a safe and effective method for performing vestibular nerve sectioning. Until now, the endoscope has been used primarily as an adjunct to the operating microscope in surgery at the cerebellopontine angle. In addition, previous endoscopic techniques typically require a third hand to manipulate the endoscope. With the 2-handed endoscopic-directed technique, however, the endoscope is used as the primary means of visualization, and the unique design of this endoscope allows for a bimanual procedure without the requirement of a cosurgeon. Advantages of using this techniqu...

Advances in Molecular Genetics of Hirschsprung's Disease.
Abstract Hirschsprung's disease (HSCR) is a developmental disorder of the enteric nervous system, which occurs due to the failure of neural crest cells to fully colonize the gut during embryonic development. It is characterized by the absence of the enteric ganglia in a variable length of the intestine. Substantial progress has been made in understanding the genetic basis of HSCR with the help of advanced genetic analysis techniques and animal models. More than 11 genes have been found to be involved in the pathogenesis of HSCR. The RET gene is the most important susceptibility gene involved in HSCR with both codin...

Global and regional alterations of hippocampal anatomy in long‐term meditation practitioners
AbstractStudies linking meditation and brain structure are still relatively sparse, but the hippocampus is consistently implicated as one of the structures altered in meditation practitioners. To explore hippocampal features in the framework of meditation, we analyzed high‐resolution structural magnetic resonance imaging data from 30 long‐term meditators and 30 controls, closely matched for sex, age, and handedness. Hippocampal formations were manually traced following established protocols. In addition to calculating left and right hippocampal volumes (global measures), regional variations in surface morphology were d...

Cancer cachexia alters intracellular surfactant metabolism but not total alveolar surface area
Abstract Dyspnoea is frequently observed in cancer cachectic patients. Little is known whether this is accompanied by structural or functional alterations of the lung. We hypothesized that in analogy to calorie restriction cancer cachexia leads to loss of alveolar surface area and surfactant. Mice were subjected to subcutaneous injection of Lewis lung carcinoma cells (tumour group, TG) or saline (control group, CG). Twenty-one days later blood samples and the lungs were taken. Using design-based stereology, the alveolar surface area and the lamellar body (Lb) content were quantified. Messenger RNA expression...

Three-dimensional shape differences in the bony pelvis of women with pelvic floor disorders
Conclusions Pelvic shape in women with PFDs is characterized by the proportional mediolateral enlargement of the pelvic midplane and ischial eversion near the subpubic arch, consistent with inferolateral migration of the attachment points for the levator ani and correspondingly lateral displacement. These movements may result in increased strain on the pelvic floor’s muscular and connective tissues, increasing the risk of failure over a woman’s lifetime.

Neural Stem Cells Enhance Nerve Regeneration after Sciatic Nerve Injury in Rats
Abstract With the development of tissue engineering and the shortage of autologous nerve grafts in nerve reconstruction, cell transplantation in a conduit is an alternative strategy to improve nerve regeneration. The present study evaluated the effects and mechanism of brain-derived neural stem cells (NSCs) on sciatic nerve injury in rats. At the transection of the sciatic nerve, a 10-mm gap between the nerve stumps was bridged with a silicon conduit filled with 5 × 105 NSCs. In control experiments, the conduit was filled with nerve growth factor (NGF) or normal saline (NS). The functional and morpholog...

The distribution of HCN2-positive cells in the gastrointestinal tract of mice.
This study investigated the distribution of HCN2-positive cells in the mouse GI tract using immunohistochemistry. To identify the nature of these HCN2 cells, anti-ChAT and anti-Kit antibodies were used to co-label neurons and the interstitial cells of Cajal (ICCs), respectively. Additionally, differences in the distribution of HCN2-positive cells within the GI tract were also analyzed. Our results showed that HCN2 channels were mainly located within the myenteric neurons of the enteric nervous system in the GI tract. Double-staining revealed that HCN2-positive neurons were labeled by ChAT, indicating that these HCN2-positi...

Greater saphenous vein evaluation from computed tomography angiography as a potential alternative to conventional ultrasonography
Conclusions: Indirect venography by CTA correlates well with US for GSV mapping in the lower extremity and offers significant reduction in imaging-related preoperative charges. CTA is sensitive and accurate for detecting GSVs that are appropriate for bypass. Furthermore, CTA allows AP and lateral evaluation of the GSV throughout its anatomic course. As CTA is often performed prior to arterial bypass, indirect evaluation of the GSV using preoperative CTA should be considered a promising alternative to the use of US.

The sinuvertebral nerves at the craniovertebral junction: A microdissection study
AbstractBogduk et al. (1988, Spine 13:2–8) noted that the joints and ligaments at the cervico‐occipital region are susceptible to whiplash injury. The upper three cervical sinuvertebral nerves (SVNs) at the craniovertebral junction (CVJ) are thought to be responsible for mediating pain from the ligaments, dura mater, and soft tissues of the posterior cranial fossa and upper cervical column. The purpose of this study was to describe in detail the origin and course of the SVNs at C0–C1, C1–C2, and C2–C3 intervertebral levels and their anterior intraspinal distribution.

Surgical management of portal hypertension in children
The management of children with portal hypertension has dramatically changed during the past decade, with an improvement in outcome. This has been achieved by improved efficiency of endoscopic variceal control and the success of liver transplantation. Emergency surgical shunt procedures are rarely required, with acute bleeding episodes generally controlled endoscopically or, occasionally in adults, by interventional radiological procedures. Portosystemic shunts may be considered as a bridge to transplant in adults but are rarely used in this context in children. Nontransplant surgery or radiological interventions may still...

Martius flap: historical and anatomical considerations
Abstract Martius flap is used infrequently by urologists and coloproctologists for repair of fistulae in the perineal region, and is usually missing from the reconstructive palette of plastic surgeons. There is a considerable confusion regarding what the Martius flap contains. It may contain skin, fat, or muscle from the labium major region. In the original description, Heinrich Martius applied the bulbocavernous/bulbospongious muscle for repair of urethra-vaginal fistula. Nowadays, what is known as Martius flap contains the more voluminous labium major fat pad mostly independent of the above muscle. In cada...

Commentary on ‘AAA with a Challenging Neck: Early Outcomes Using the Endurant Stent-graft System’
Latest generation devices for endovascular aortic repair (EVAR) are raising an increasing interest due to the possibility to extend effective treatment to aneurysm anatomies judged unfeasible by endovascular route in the past. The Endurant Medtronic stent graft has been introduced as an improved device to manage abdominal aortic aneurysms (AAAs) with difficult necks. In this issue of EJVES, Setacci et al. showed that the Endurant can also work well on really adverse neck anatomies using compelled off-label indications such as short neck length 60° neck angle, significant thrombus or conical neck. Despite the adverse anat...

Cardiac specific ATP-sensitive K+ channel (KATP) overexpression results in embryonic lethality
In conclusion, KATP channels are present and active in embryonic myocytes, and overexpression causes in utero heart failure and results in embryonic lethality. These results suggest that the KATP channel may have an important physiological role during early cardiac development.Highlights: ► KATP currents are detected in embryonic cardiomyocytes since early cardiac development. ► Embryos overexpressing KATP demonstrate normal cardiac looping pattern. ► Transgenic mice overexpressing KATP channel subunits demonstrate embryonic lethality. ► The embryonic lethality of the KATP overexpressing embryos is a result of in utero heart failure.

MR Imaging of the Temporomandibular Joint
MR imaging allows detailed evaluation of temporomandibular (TMJ) anatomy because of its inherent tissue contrast and high resolution. Joint biomechanics can be assessed through imaging patients in the closed and open jaw positions. Despite the accuracy of MR imaging in detecting disc position, results must be interpreted together with clinical findings, because an anteriorly displaced disc can be seen in up to one-third of asymptomatic patients, and a normal disc position can be seen in up to one-quarter of symptomatic patients. Interpretation of MR imaging requires knowledge of the normal anatomy and an understanding of n...

Three-Dimensional Analysis of the Islet Vasculature.
Abstract The pancreatic islets of Langerhans are highly vascularized structures scattered throughout the pancreas that contain a capillary network 5-10 times denser than that of the exocrine pancreas. A simple method for three-dimensional (3D) analysis of this intricate intraislet vasculature has been difficult because of the intrinsic opacity of the pancreas. We developed a whole-mount imaging technique that allows relatively easy visualization of the islet vasculature. In combination with confocal microscopy and the use of 3D imaging software, we were able to readily reconstruct the 3D architecture of an islet, a...

Cortical Bone Response to the Presence of Load-Bearing Percutaneous Osseointegrated Prostheses.
Abstract Although the current percutaneous osseointegrated (OI) prosthetic attachment systems are novel clinical treatments for patients with limb loss, there have only been limited translational studies undertaken to date. To bridge this knowledge gap, from a larger study group of 86 animals that were implanted with a novel percutaneous OI implant construct, 33 sheep were randomly selected from the 0-, 3-, 6-, 9- and 12-month groups for histomorphometric analyses of periprosthetic cortical bone tissue. At necropsy, implanted and nonimplanted limbs were harvested and processed for the evaluation of cortical bone po...
