Central odontogenic fibroma: a case report

Central odontogenic fibroma is a rare odontogenic neoplasm that originates from odontogenic ectomesenchyme. Here, a case of central odontogenic fibroma in a 17-year-old male is reported. Since the present case showed a multilocular radiolucency with partially ill-defined border between the right mandibular condyle and the distal root of the right mandibular third molar, differential diagnosis involved a wide range of pathosis from benign lesions like ameoloblastic fibroma and odontogenic myxoma to more aggressive lesions such as desmoplastic fibroma, juvenile aggressive fibromatosis, or fibrosarcoma

Central odontogenic fibroma: a case report with long-term follow-up

An osteolytic tumour of the mandible with prominent expansive growth on the alveolar ridge and displacement of the involved teeth is described in a 28-year-old man. The lesion was diagnosed as a central odontogenic fibroma, an uncommon benign neoplasm derived from dental apparatus, and was removed by curettage. The patient remains asymptomatic after thirteen years of follow-up, which supports the claimed indolent behavior of this poorly documented disease and the adequacy of a conservative surgical treatment

On the question of accumulation of ice-melt water south of the ice in the Chukchi Sea.

The processes controlling the distribution of melt water from the retreating ice edge in summer in the Chukchi Sea were examined in order to provide evidence of the flow regime. Current and salinity data from the National Oceanographic Data Center (NODC) files and from four MIZPAC cruises were utilized in this work. An increase in melt-water content towards the ice in the approximately 30 km wide icemelt zone as well as an abrupt salinity decrease were observed. This effect was presumed to be due to scattering of ice from a diffuse ice margin accompanied by melting. North of the ice edge the fresh-water content was greater 2 than that of southerly water by an amount (150-200 gm/cm ) equivalent to the thickness of the ice cover. These findings together with an independent comparison of transport times and ice satellite data produce good evidence that the current flows faster than the ice retreats during summer in the eastern half of the Chukchi Sea.http://archive.org/details/onquestionofaccu00handLieutenant, United States NavyApproved for public release; distribution is unlimited

LEVEL OF OBJECT RELATIONS AND MARITAL ADJUSTMENT INFLUENCING PARENTS\u27 CHOICE OF CHILDBIRTH PROCEDURE (OBSTETRICS)

This study was designed to improve the understanding of the factors that influenced a couple\u27s choice of childbirth procedure for their first child. It was hypothesized that parents who chose prepared childbirth (PCB), with its emphasis on marital cooperation and active participation, would have higher levels of object relations and marital adjustment than those who chose the traditional childbirth procedure (TCB) with its reliance on the obstetrical use of anesthesia and instrumentation. All of the 30 couples in the PCB group and none of the 30 couples in the TCB group attended Lamaze classes. All subjects were married, between 21 and 30 years old, had completed high school, lived in the Danbury, Connecticut area, were Caucasian, reported no history of psychiatric hospitalizations and the expectant mothers were in their third trimester of pregnancy. There were no significant differences in ages, number of years of schooling completed, number of years married and socioeconomic status. No expectant mothers were included if they required specialized childbirth procedure because of known medical preconditions. The level of object relations was judged using the Krohn Object Representation Scale applied to the manifest content of a dream submitted by 110 of the 120 subjects. The degree of marital adjustment was measured by the Dyadic Adjustment Scale (DAS), a self-administered questionnaire. The results supported the hypothesis that the PCB group would have significantly greater marital adjustment. The PCB group did not have a higher level of object relations. There was no significant association between the level of object relations and the degree of marital adjustment. For PCB spouses only, there was a significant association between husbands\u27 and wives\u27 levels of object relations. Also, there was a significant association between PCB spouses on four DAS subscales, satisfaction, cohesion, affection and total adjustment whereas TCB spouses were significantly associated on one, total marital adjustment. Both groups responded to questions in a way that minimized marital differences. The findings may suggest that, in this middle class sample, the choice of PCB, heretofore not considered capricious behavior, may now be more related to the trendiness of childbirth preparation because of its current popularity

Power-Aware Video Decoding using Real-Time Event

Multimediaap p lications have to receive su#cient resource allocations to maintain their desired levels of Quality of Service (QoS). On the other hand, in mobile environments, the devices on which these ap p lications must run have to minimizep ower consump tion top rolongbattery life. Our work focuses on the QoS issues in the event-driven distribution of multimedia streams between mobile users, where a source p rovides interactive video in the form of streams of data events to multip le remote sinks. This pp er addresses the p ower-aware execution of event handlers at such event sinks. In p rticular, an adapg ve apR1 ach to the dynamic selection of a suitable CPU clock frequency of a mobile device is shown sup erior to non-adapg vep ower management. This apA' ach (a) minimizesp ower consumpF on while also (b) guaranteeing that a given event handler finishes its execution withinap p lication-sp ecific timingconstraints. This is realized by dynamically measuringthep rogress of event handler functions and then usingthis information to re-adjust the clock frequency for the current event and to select ap - pg p riate clock frequencies for future events
