Ectopic pancreas also known as heterotopic pancreas (HP) is a rare congenital anomaly, mainly found as incidental finding during autopsy or abdominal exploration for an other condition. Incidence rate is probably underestimated as patients are mostly asymptomatic; otherwise, it is capable of producing symptoms depending on its location, size, often appearing in the 4th-to-6th decades. Complications such as inflammation, obstruction, bleeding, and malignancy degeneration must be considered. Pediatrics cases are very rare, generally concerning HP within Meckel's diverticulum, manifesting by gastrointestinal bleeding and intussusception...

OBJECTIVE: The anterior transpetrosal (ATP) approach is the most appropriate approach for petroclival meningiomas, which are typically located from the dorsum sellae to the upper border of the internal acoustic meatus (IAM). Although neurosurgeons can resect over this area if the tumor is detached from the dura, tumors within the indication area for petroclival meningiomas is insufficient for the selection of the ATP approach because it can be difficult to evaluate whether the tumor is attached or only touching the dura...

OBJECTIVE The transpterygoid extension of the endoscopic endonasal approach provides exposure of the petrous apex, Meckel's cave, paraclival area, and the infratemporal fossa. Safe and efficient localization of the lacerum segment of the internal carotid artery (ICA) is a crucial part of such exposure. The aim of this study is to introduce a novel landmark for localization of the lacerum ICA. METHODS Ten cadaveric heads were prepared for transnasal endoscopic dissection. The floor of the sphenoid sinus was drilled to expose an extension of the pharyngobasilar fascia between the sphenoid floor and the pterygoid process (the pterygoclival ligament)...

CEP290 mutations cause a spectrum of ciliopathies from Leber congenital amaurosis type 10 (LCA10) to embryo-lethal Meckel syndrome (MKS). Using panel-based molecular diagnosis testing for inherited retinal diseases, we identified two individuals with some preserved vision despite biallelism for presumably truncating CEP290 mutations. The first one carried a homozygous 1 base-pair deletion in exon 17, introducing a premature termination codon (PTC) in exon 18 (c.1666del; p.Ile556Phefs*17). mRNA analysis revealed a basal exon skipping (BES) of exon 18, providing mutant cells with the ability to escape protein truncation, while disrupting the reading frame in controls...

Impairment or stimulation of the immune system by ionizing radiation (IR) impacts on immune surveillance of tumor cells and non-malignant cells and can either foster therapy response or side effects/toxicities of radiation therapy. For a better understanding of the mechanisms by which IR modulates T-cell activation and alters functional properties of these immune cells, we exposed human immortalized Jurkat cells and peripheral blood lymphocytes (PBL) to X-ray doses between 0.1 and 5 Gy. This resulted in cellular responses, which are typically observed also in naïve T-lymphocytes in response of T-cell receptor immune stimulation or mitogens...

Identification of biological markers predicting the onset of neoplasia in patients with long-standing ulcerative colitis (UC) could allow for risk stratification in this population. In this study, we retrospectively identified subjects with chronic UC who developed colon neoplasia ( n = 16) matched to UC patients who never developed neoplasia. RNA was extracted from archived colonic biopsies obtained at an interval of 1-2 years prior and 3-5 years prior to the onset of neoplasia. miRNA expression was assessed using Nanostring arrays in 12 subjects, and significantly up-regulated miRNAs were evaluated by real time pcr in the entire cohort of patients...

BACKGROUND: In contrast to conventional mandatory ventilation, a new ventilation mode, expiratory ventilation assistance (EVA), linearises the expiratory tracheal pressure decline. OBJECTIVE: We hypothesised that due to a recruiting effect, linearised expiration oxygenates better than volume controlled ventilation (VCV). We compared the EVA with VCV mode with regard to gas exchange, ventilation volumes and pressures and lung aeration in a model of peri-operative mandatory ventilation in healthy pigs...

Meckel's diverticulum is a congenital anomaly which can become complicated or remain asymptomatic throughout life. During pregnancy, however, diverticulum infection could become a serious complication. Diverticulum necrosis and perforation are complications that increase morbidity in pregnancy, both maternal and fetal. The rarity of the condition and the maternal physiological changes in pregnancy make the diagnosis difficult. We present the case of a Meckel's diverticulum gangrene in third trimester pregnancy, atypical case due to advanced pregnancy where the risk-benefit balance was carefully evaluated on one hand because of the risk of infection associated with expectant management and on the other hand the risk and complications of iatrogenic preterm premature birth...

We report a case of a patient presenting with small bowel obstruction secondary to an enteric ileal duplication cyst. Although common in infancy, they are rarely seen in adults. Radiologically they may be difficult to distinguish from a Meckel diverticulum and often the diagnosis is made retrospectively. Optimal management of the asymptomatic adult is unclear.

BACKGROUND: Neoplasms located in Meckel's cave account for 0.2-0.5% of all intracranial tumors. This area is the site of many types of pathological lesions, most often trigeminal nerve schwannomas and meningiomas. Melanin-containing tumors are very rare in this area. These tumor types can be suspected if the MR-characteristics of a tumor has some differences in comparison with other types of central nervous system neoplasms. In fact, differential diagnosis of melanotic tumors is based mainly on the histopathological criteria and immunohistochemical profile...

Background: Craniofacial malformations are among the most common congenital anomalies. Cranial neural crest cells (CNCCs) form craniofacial structures involving multiple cellular processes, perturbations of which contribute to craniofacial malformations. Adhesion of cells to the extracellular matrix mediates bidirectional interactions of the cells with their extracellular environment that plays an important role in craniofacial morphogenesis. Talin (tln) is crucial in cell-matrix adhesion between cells, but its role in craniofacial morphogenesis is poorly understood...

RATIONALE: Annular pancreas (AP) is recognized as a cause of duodenal obstruction in children, while children with Meckel's diverticulum (MD) are usually asymptomatic. Here we present a rare case with both AP and MD, which was identified by abdominal exploration during diamond-shaped duodenoduodenostomy. PATIENT CONCERNS: A "double-bubble" sign was found by ultrasound at 35 week of pregnancy. After 39 weeks of pregnancy, the male patient was transferred to the Department of General Surgery, Children's Hospital of Soochow University because of a suspected duodenal stenosis...

Maximal anaerobic exercise, is a short high intensity effort, involves activation of the hypothalamus-pituitary-adrenal axis, and may suggest hypoalgesic effects. In addition, this exercise-induced muscle pain may contribute to hypoalgesia via the pain inhibits pain phenomenon, which is related to the diffuse noxious inhibitory control (DNIC) mechanism. We aimed to investigate whether: 1) a single bout of 30 s maximal anaerobic exercise has an analgesic effect on experimental pain sensitivity; 2) DNIC is the underlying mechanism of anaerobic exercise-induced hypoalgesia (EIH)...
