A 43 years old female presented with recurrent urinary tract infections. Her past history included a laparoscopic colposuspension aged 33 years in which mesh was stapled to the ileopectineal ligament. She developed recurrent incontinence 12 years later and underwent transvaginal tape insertion. Cystoscopy revealed two encrusted staples in her bladder which had migrated following her colposuspen...

Thanks to recent improvements, computational methods can now be used to convert triangular meshes into quadrilateral meshes so that the quadrilateral elements capture well the principal curvature directional fields of surfaces and intrinsically have surface parametric values. In this study, a quadrilateral mesh generated using the mixed integer quadrangulation technique of Bommes et al. is used...

PURPOSE To evaluate the tissue integration of a double-sided mesh after fixation in diaphragm and to study the diaphragmatic mobility by ultrasound. METHODS Twenty male Wistar rats were used. The animals were assigned into two equal groups according to the day of euthanasia. The animals were anesthetized and a 1.5 x 1.5 cm of double-layer mesh was inserted between the diaphragm and the liver....

We read with interest the paper by Ikeda et al. [1] regarding the treatment of catamenial pneumothoraces. We agree with the authors that the pathology of true catamenial pneumothorax is not clear. However, in most cases, diaphragmatic fenestrations play a role. On the left, the fenestrations are frequently plugged by the omentum. On the right, however, the liver prevents such plugging, which ac...

Gastric volvulus is an uncommon but serious surgical condition mandating an early diagnosis and surgical intervention. It may present either acutely or chronically with epigastric pain, retching and vomiting. There are two types of gastric volvulus: organo-axial and mesentero-axial. We report a case of a mesentero-axial gastric volvulus in a 49-year-old woman with a left-sided diaphragmatic her...

We develop an adaptive finite element method for island dynamics in epitaxial growth. We study a step-flow model, which consists of an adatom (adsorbed atom) diffusion equation on terraces of different height; thermodynamic boundary conditions on terrace boundaries including anisotropic line tension; and the normal velocity law for the motion of such boundaries determined by a two-sided flux, t...

Bochdalek hernia is a rare surgical condition primarily diagnosed in infants. Morgagni hernia is more commonly identified in adults. A subset of patients with a Bochdalek hernia, especially those with a right-sided defect, may also be diagnosed during adulthood. Both adult forms of CDH may be discovered incidentally or diagnosed as part of the investigation of nonspecific gastrointestinal or re...

A massive inguinoscrotal hernia extending below the midpoint of the inner thigh, in a standing position, constitute a 'giant' inguinoscrotal hernia. A 74-year-old male presented with giant left sided inguinal hernia for the last 30 years. Patient underwent open repair under general anesthesia after perioperative respiratory exercise. Standard hernia repair identified a sliding hernia containing...

multicast routing is one of the most important services in multi radio multi channel (mrmc) wireless mesh networks (wmn). multicast routing performance in wmns could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. in this paper we want to address the multicast routing problem for a given channel assignment in wmns. the channels...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...
