Numerical limit analyses have been used to evaluate the stability of the 17th Street Canal I-wall levee during Hurricane Katrina. The potential formation of a water-filled gap along the canal-side soil-wall interface at failure is included in both the lowerand upper-bound formulations. The analyses replicate published two-dimensional (2D) cross sections and soil properties developed in forensic...

Introduction: Meatoplasty is the final and essential step in performing effective canal wall down surgery for chronic otitis media. In this article we review some previous techniques and discuss our preferred method. Materials and Methods: In this observational case series study, we used this technique in 53 patients (28 male and 25 female) between January 2005 and January 2008. Our survey was ...

OBJECTIVE To determine functional results after lateral semicircular canal fenestration on congenital conductive hearing loss. STUDY DESIGN Case series with chart review. SETTING Amir-Alam otolaryngology tertiary referral center. SUBJECTS AND METHODS Twenty patients with congenital oval window malformations who were not candidates for ossicular reconstruction underwent lateral semicircula...

Dumb bell shaped tumours have been reported infrequently in literature of which the usual ones being retroperitoneal tumours extending to the scrotum via the inguinal canal or extending through the femoral canal and presenting in the thigh. Cases of a thigh liposarcoma extending to the retroperitoneum are very rare. We could come across only publications in this regard 5. We report a patient wi...

OBJECTIVES An important factor that interferes with the bonding between the root canal wall and resin cement is the root canal sealer remnant. There is controversy about the effect of eugenol-containing sealers on the bond strength between resin cements and fiber post. The aim of this study was to evaluate the effect of the type of endodontic sealer on the bond strength of FRC posts cemented wi...

Chronic otitis media (COM) is completely treated with a single procedure in most patients but may require multiple surgeries in some cases. The main goals of open cavity mastoidectomy are to completely eradicate the disease, create a large enough meatus for examination and mastoid air cells, and provide a self-cleaning epithelized dry cavity, and achieve maximum hearing. In this report, we pres...

Hunter et al summarized their 10 years’ experience of only 7 patients undergoing cochlear implant (CI) surgery after previous canal wall-down mastoidectomy using a single-layer external auditory canal overclosure technique. The authors seem to be surprised that their findings of 2 ear canal failures contradict the experience of 303 patients reported in the literature—including our own study. In...

Anterior abdominal wall defects can be difficult and daunting problems to solve anywhere in the world. These musculofascial defects may range from simple incisional hernias following previous laparotomy to complex open abdominal wounds with exposed viscera and enteric fistulas following traumatic injury or necrotizing fasciitis. These latter wounds are commonly associated with significant funct...
