#1
Yang Xu, Myung Chan Gye
Citrate esters have been considered as alternatives to phthalate plasticizers. Being considered to have low toxicity in mammals, their toxicological information for aquatic animals remains poorly understood. We examined the developmental toxicity of citrate esters including tributyl O-acetylcitrate (ATBC), triethyl 2-acetylcitrate (ATEC), and trihexyl O-acetylcitrate (ATHC) together with dibutyl phthalate (DBP) based on the frog embryo teratogenesis assay-Xenopus (FETAX). ATBC has the lowest 96 h LC50 and 96 h EC50 values...

BACKGROUND: Several techniques have been described for the percutaneous treatment of trigeminal neuralgia; however, each has significant drawbacks. We propose a new technique for percutaneous balloon compression of the trigeminal ganglion and distal trigeminal nerve using electromagnetic (EM) neuronavigation. METHODS: The procedure was performed in 17 consecutive patients with trigeminal neuralgia. Patients were then followed up with telephone interview. We also performed a cadaveric validation study to further investigate the accuracy of the technique using dye...

Meckel's cave is a dural recess in the posteromedial portion of the middle cranial fossa that acts as a conduit for the trigeminal nerve between the prepontine cistern and the cavernous sinus, and houses the Gasserian ganglion and proximal rootlets of the trigeminal nerve. It serves as a major pathway in perineural spread of pathologies such as head and neck neoplasms, automatically upstaging tumours, and is a key structure to assess in cases of trigeminal neuralgia. The purpose of this pictorial review is threefold: (1) to review the normal anatomy of Meckel's cave; (2) to describe imaging findings that identify disease involving Meckel's cave; (3) to present case examples of trigeminal and non-trigeminal processes affecting Meckel's cave...

The mammalian middle ear represents one of the most fundamental features defining this class of vertebrates. However, the origin and the developmental process of the incus in the human remains controversial. The present study seeks to demonstrate all the steps of development and integration of the incus within the middle ear. We examined histological sections of 55 human embryos and foetuses at 6 to 13 weeks of development. At 6 weeks of development (16 Carnegie Stage), the incus anlage was found to be lateral to this vein at the cranial end of the first pharyngeal arch...

PURPOSE: Meckel's diverticulum (MD) is a common congenital anomaly caused by failure of involution of the omphalomesenteric duct. Enthusiasm for minimally invasive surgery (MIS) in children has burgeoned as technologies have advanced, but the outcomes of laparoscopic resection in comparison to open laparotomy for MD remain poorly defined. We queried a large national database to compare current practice patterns and clinical outcomes between surgical approaches for MD in the pediatric population...

The case of an 11-year-old boy with an orange-associated ileus in the setting of a mesodiverticular band from a Meckel's diverticulum is reported herein. Computed tomography showed a small bowel feces sign. He underwent laparoscopic-assisted surgery, and intraoperative findings revealed a Meckel's diverticulum associated with a mesodiverticular band distal to dilated small bowel. After resection of the Meckel's diverticulum and inspection of the intestinal contents proximal to the obstruction, it was apparent that undigested food material was impacted proximal to the obstruction...

OBJECTIVE Despite the advances in skull base techniques, large petroclival meningiomas (PCMs) still pose a challenge to neurosurgeons. The authors' objective of this study was to describe a pretemporal trans-Meckel's cave transtentorial approach for large PCMs and to report the surgical outcomes. METHODS From 2014 to 2017, patients harboring large PCMs (> 3 cm) and undergoing their first resection via this procedure at the authors' institute were included. In combination with pretemporal transcavernous and anterior transpetrosal approaches, the trans-Meckel's cave transtentorial route was created...

OBJECTIVE Meningiomas arising from the cavernous sinus (CS) continue to be a significant technical challenge, and resection continues to carry a relatively higher risk of neurological morbidity in patients with these lesions because of the tumor's proximity to neurovascular structures. The authors report the surgical outcomes of 9 patients with primary CS meningiomas (CSMs) that were surgically treated using a minimal anterior and posterior combined (MAPC) transpetrosal approach, and they emphasize the usefulness of the approach...

MEDICAL HISTORY AND CLINICAL FINDINGS:  A 43-year old male patient was admitted because of diffuse abdominal discomfort for two days, which had started in the upper abdomen; medical history, no previous surgical interventions at the abdomen. INVESTIGATIONS:  Gastroscopy and abdominal ultrasound revealed only a mild gastritis. Laboratory parameters: showed only a slight leucocytosis (10 610/µL). On the 1st day of the hospital stay, the patient developed a worsening of the abdominal symptoms with distended abdomen, sounding bowel movements and recurrent vomiting, which were interpreted as acute abdomen by the surgeon on call leading to the indication of a surgical intervention...

INTRODUCTION: Gastrointestinal Stromal Tumors (GISTs) are a rare slow growing malignancy, accounting for less than 1% of all gastrointestinal (GI) tract tumors. These tumors are usually discovered incidentally by endoscopy, surgery or radiology. However on occasions they may present with significant symptoms including GI blood loss. This case report discusses an atypical presentation of a GIST in a 57-year-old female. CASE PRESENTATION: A 57-year-old woman presented to the emergency department following one episode of melena...

We report a case of a vesicoenteric fistula arising from an adenocarcinoma of ectopic pancreatic tissue in a Meckel diverticulum in a 58-year-old man. The patient suffered from refractory micturition pain and increased urinary frequency. Computerized tomography with a contrast agent showed a ring-shaped enhanced mass near the dome of the urinary bladder. Magnetic resonance imaging showed a cystic mass close to the urinary bladder with partly irregular wall and fistula formation to the urinary bladder. Surgical findings showed a Meckel diverticulum in the ileum, which formed a fistula with the urinary bladder, and Meckel diverticulectomy and partial cystectomy were performed...

The association between omphalomesenteric duct remnants and other digestive tract malformations is not rare. Most associated anomalies are reported with Meckel's diverticulum. We report two associated anomalies which were never reported: an ileal stenosis and an ileal duplication. Surgeons must be aware of associated anomalies to prevent post-operative complications.

OBJECTIVE: To describe an endoscopic anterolateral surgical route to the lateral portion of Meckel's cave. METHODS: A sublabial transmaxillary transpterygoid approach was performed in 6 cadaveric heads (12 sides). A craniectomy was drilled between the foramen rotundum (FR) and foramen ovale (FO) with defined borders. Extradural dissection was performed up to the V2-V3 junction of the trigeminal ganglion. The working space was analyzed using anatomical measurements...

Many actin filaments in animal cells are co-polymers of actin and tropomyosin. For many of these co-polymers, non-muscle myosin II associates to establish a contractile network. However, the temporal relationship of these 3 proteins in the de novo assembly of actin filaments is not known. Intravital subcellular microscopy of secretory granule exocytosis allows the visualisation and quantitation of the formation of an actin scaffold in real time with the added advantage that it occurs in a living mammal, under physiological conditions...
