A 2-mo-old, female blue-and-yellow macaw (Ara ararauna) presented with severe abdominal distension, pain, and respiratory distress. Ultrasonographic examination detected a heterogeneous mass with multiple anechoic areas, compatible with a multilocular cyst, occupying most of the coelomic cavity. Postmortem examination revealed a mass of 12.0 × 8.5 × 5.0 cm, which had an irregular surface and was connected by a pedicle to the ileum. This mass compressed and displaced the liver, proventriculus, gizzard, and intestines cranially to the left...

A Meckel's diverticulum is a vestigial remnant present in approximately 2% of the population. Fewer than 10% of patients with a Meckel's diverticulum develop clinical complications, and such findings are exceedingly rare in the geriatric population. We present a case of perforated Meckel's diverticulitis with a fistulous tract involving the anterior abdominal wall in an 85-year-old male.

BACKGROUND: The anterior transpetrosal approach (ATPA), during which the trigeminal nerve is manipulated, has a risk of eliciting the trigemino-cardiac reflex (TCR). The objective of this study was to assess the risk of the TCR during the ATPA. METHODS: The surgical records of 92 patients who had surgical treatment via the ATPA at the Keio university hospital between December 2005 and June 2015 were retrospectively analyzed. They were divided into two groups on the basis of the occurrence of the TCR during surgery, and their clinical and tumor characteristics were compared...

INTRODUCTION: Meckel's diverticulum (MD) commonly presents as gastrointestinal bleeding in the pediatric population and intestinal obstruction in adults. There is no consensus for surgical excision of an incidentally diagnosed MD. We present a hitherto unreported vascular cause of intestinal gangrene due to MD. CASE PRESENTATION: A 16year old boy was referred as an acute abdomen for tertiary hospital management. Clinical examination and CT suggested small bowel obstruction and emergency laparotomy was performed...

INTRODUCTION: Enterovesical fistulas usually result from diverticulitis, Crohn's disease, or colorectal cancer. A perforated Meckel's diverticulum can exceptionally result in an vesico-diverticulum fistula, as noted in only seven previously reported cases. CASE REPORT: A 35-year old Arabic male, quadriplegic,who presented epigastralgia evolving for a week, associated with abdominal distension and cloudy urine. On examination he was feverish (38.5°C), dehydrated with tenderness in the entire distended abdomen; rectal examination revealed a hypotonic sphincter with no other abnormality...

We report a patient with diffuse peritonitis due to perforation of Meckel's diverticulum. This patient was referred to the operating room and underwent bowel resection segment encompassing the area of the diverticulum and terminoterminal primary enteroanastomosis on two levels with good evolution. The diverticulum complications are often related to the presence of ectopic mucosa, specially the gastric and pancreatic type. Since preoperative diagnosis is difficult and infrequent, in most cases this anomaly is confirmed only during surgery...

Human ciliopathies are a class of multi-organ genetic disorders caused by defects of proteins expressed at the primary cilium, an organelle present on the cell surface of almost all cell types. Thus far, dozens of causative genes for ciliopathies have been identified and many of them are known to cause allelic disease. Of particular interest is the TMEM67 gene, encoding the transmembrane protein meckelin. The involvement of the mutant TMEM67 gene is known to be associated with a broad range of clinical presentations, namely Joubert syndrome 6 (JBTS6), nephronophthisis 11 (NPHP11), Bardet-Biedel syndrome (BBS), COACH syndrome, and lethal Meckel syndrome type 3 (MKS3)...

BACKGROUND: Trigeminal neuralgia (TN) is the most common type of facial neuralgia with incidence of 26.8/100,000 person year. In general, this scenario is characterized by a lancinating, unilateral, paroxysmal pain in the area of the fifth cranial nerve. Several treatment methods, including the injection of ethyl alcohol or butyl alcohol into the ganglion, the glycerol injection into the trigeminal cistern, peripheral nerve divisions, the radiofrequency thermocoagulation of the preganglionic fibers, and radiosurgery has been used for TN...

Meckel's diverticulum (MD) is the most common gastro-intestinal congenital malformation (approximately 2% in the overall population). The lifetime risk of related complications is estimated at 4%. These include gastro-intestinal bleeding, obstruction or diverticular inflammation. Diagnosis is difficult and rarely made, and imaging, especially in the case of complicated disease, is often not helpful; however exploratory laparoscopy is an important diagnostic tool. The probability of onset of complication decreases with age, and the diagnosis of MD in the adult is therefore often incidental...

Studies indicate that persistent Salmonella colonization occurs in poultry that are infected early in life, leading to both food safety and public health concerns. Development of improved preharvest Salmonella management strategies is needed to reduce poultry product contamination. The objective of this study was to evaluate the efficacy of a product containing medium chain fatty acids (MCFA) for reducing early Salmonella colonization in turkey poults. Day-of-hatch turkeys were provided a standard starter diet supplemented with MCFA at 0 (negative and positive controls), 1...

Meckel's diverticulum is the most prevalent congenital abnormality of the gastrointestinal tract. Clinical symptoms can result in pain, bleeding and perforation caused by peptic ulceration. Among all imaging modalities, Tc-99m pertechnetate scintigraphy is the most sensitive method for Meckel's diverticulum diagnosis, but only mentioned in a few publications. We report the case of a young child with rectal bleeding related hemorrhagic Meckel's diverticulum. Endoscopy and ultrasound were normal. The diagnosis was done by scintigraphy with technetium revealing an accumulation of radiotracer by mucous cells in ectopic gastric mucosa, which allows a detection of Meckel's diverticulum...

We report an otherwise healthy 32-year-old man with portal hypertension, variceal bleeding, and congenital hepatic fibrosis with ductal plate malformation. Genetic screening identified two TMEM67 mutations. Biallelic TMEM67 mutations are known to cause Joubert/Meckel syndrome or nephronopthisis with hepatic fibrosis, but have never been found in isolated hepatic fibrosis.

The symptomatic presentation of Meckel's diverticulum (MD) depends on a person's age, sex, and presence or absence of ectopic gastric tissue. There are no differences in the prevalence of asymptomatic MD between males and females; however, symptomatic MD has a distinct male predominance with a male-to-female ratio ranging from 2:1 to 5:1 in children. Furthermore, if the ectopic tissue contains gastric mucosa, MD has a greater chance of becoming symptomatic. Studies have shown that acid secretion is more likely to occur in male infants compared to female infants...

We investigate a ternary system that consists of itraconazole (ITZ) and two polymers: povidone K12 and Carbopol 907. The interactions between these two polymers and their effects on the properties of ternary ITZ amorphous solid dispersions (ASDs) are studied. These two polymers can form a water-insoluble complex in acidic aqueous media. The critical pH is determined to be 4.17. The weight percentage of Carbopol 907 in the interpolymer complex range from 59 to 70%, depending on the initial ratios between these two polymers in the starting solutions...

BACKGROUND: Meckel-Gruber syndrome (MKS, OMIM #607361) is a rare pre- or perinatal lethal autosomal recessive ciliopathy caused by mutations in at least 12 known genes. It has a clinical and genetic overlap with other viable ciliopathies, especially Joubert syndrome and Joubert syndrome-related disorders. MKS is characterized by multicystic kidney dysplasia, central nervous system malformations (usually occipital encephalocele), ductal plate malformation of the liver, and postaxial polydactyly...

The cellular interaction with the extracellular matrix (ECM) modulates many key processes such as proliferation, migration, differentiation and survival. In addition, cells cultured under 3D conditions in presence of an ECM display a marked radioresistance towards ionizing radiation (IR) in comparison to conventionally 2D cultured cells. This process, also known as "cell-adhesion-mediated-radio-resistance" (CAM-RR), has been linked to the chromatin structure that differs between cells cultured on stiff surfaces versus cell grown on soft planar supports or in 3D environments...

Diverticular bleeding of the small bowel is rare and occurs primarily in adults aged more than 60 years. In younger adults, Meckel's diverticulum, a true diverticulum that congenitally occurs in the distal ileum, is the most common cause of diverticular bleeding of the small bowel. Unlike Meckel's diverticula, other kinds of small bowel diverticula are not congenital and their incidence is related to age. Furthermore, congenital true diverticular bleeding of the jejunum in adults is very rare. We report the case of a 24-year-old man with subepithelial tumor-like lesion accompanied with obscure overt gastrointestinal bleeding (OOGIB)...
