BACKGROUND AND PURPOSE Although first-choice therapy for the ranula is surgery, this choice presents technical difficulties and frequent recurrences because of insufficient surgery. We evaluated the efficacy of OK-432 sclerosis of the plunging ranula as a substitute for surgery. METHODS Twenty-one patients with plunging ranula were treated with intralesional injection of OK-432. The liquid co...

OBJECTIVES/HYPOTHESIS To describe clinical characteristics of oral mucoceles/ranulas, with a focus on human immunodeficiency virus (HIV)-related salivary gland diseases. STUDY DESIGN A descriptive and clinical study, with review of patient data. MATERIAL AND METHODS We reviewed 113 referred cases of oral mucocele. The following anatomical sites were identified: lip, tongue, and floor of the...

Plunging ranulas are rare; report of this condition is particularly limited in our environment. We present case series in children; with all cases having both oral and cervical components. It is important to note this type of presentation of plunging ranula and their appropriate management.

85 The physiography of the area is dominated by glaciated landforms carved in gneiss of the Fiordland Complex. The gneiss is generally dioritic, with gradations to quartzo-feldspathic and amphibolitic varieties, and is cut by mainly barren pegmatite veins; epidote is abundant. The rocks commonly show signs of post-consolidational shearing and crushing. There is a well defined zone of strongly c...

This paper represents a first step towards the development of two-phase CFD methods for small and large scale ship hydrodynamic applications. Two-phase level set approaches are being implemented in CFDShip-Iowa to extend the modeling capabilities of the current version 4 along with complementary experiments for validation. The experiments are conducted in an open channel flume using bottom moun...

We explore the presence of torques at the inner edges of geometrically-thin black hole accretion disks using 3-dimensional magnetohydrodynamic (MHD) simulations in a pseudo-Newtonian potential. By varying the saturation level of the magnetorotational instability that leads to angular momentum transport, we show that the dynamics of gas inside the radius of marginal stability varies depending up...

OBJECTIVE The purpose of this study was to clarify the pathogenesis of plunging ranulas in regard of the pathway of lesion propagation using CT scans. MATERIALS AND METHODS We retrospectively reviewed CT scans of 41 patients with plunging ranula. We divided plunging ranulas into two types: type 1 was defined as those directly passing through a defect of the mylohyoid muscle with the presence ...

The capacity of rainbow trout to experience fear was assessed using an avoidance learning task. Each of 13 fish was placed individually into a two-chambered shuttle tank where it could be subjected to the putative frightening stimulus of a plunging dip net in either chamber. The fish could escape from the stimulus by swimming through a doorway to the other chamber. The fish escaped from the plu...
