Cyberspace Betrayal: Attachment in an Era of Virtual Connection

Electronic technology has yielded new forms of relationship bonding as well as unique aspects of betrayal and ruptures in attachment. Four key characteristics of betrayal that differentiate online from offline experience will be identified. The inherent ambiguities in defining online sexual infidelity will point to a need to professionally define the parameters of internet betrayal in light of the ever expanding electronic revolution.     

The effect of casting procedures on rotational misfit in castable abutments

PURPOSE: Misfit of implant components has been linked to restorative complications such as screw loosening. Although previous studies have shown a correlation between rotational misfit and screw loosening, the impact of casting procedures on rotational misfit is lacking. The aim of this in vitro study was to evaluate the effect of casting procedures on rotational misfit of cast abutments when compared to machined titanium abutments. MATERIALS AND METHODS: Forty-eight external hexagonal implants and 48 abutments were placed in 4 groups of 12 samples each: (1) machined titanium abutments, (2) premachined palladium abutments cast-on with palladium, (3) plastic burnout abutments cast with nickel chromium, and (4) plastic burnout abutments cast with cobalt chromium. Rotational misfit between the external hexagon of the implant and the internal hexagon of the abutment was measured using standardized techniques and recorded in degrees. Mean values for each group were analyzed with analysis of variance and Tukey test. RESULTS: The mean rotational misfit was 1.21 +/- 0.57 degrees for machined titanium abutments, 1.77 +/- 130 degrees for cast-on abutments, 1.98 +/- 0.72 degrees for cast NiCr abutments, and 2.79 +/- 1.13 degrees for cast CoCr abutments. Significantly greater rotational misfit was recorded with cast CoCr abutments when compared to machined titanium abutments (P < .05). CONCLUSION: Rotational misfit was less than 2 degrees for all groups except for cast CoCr abutments, which demonstrated a significantly greater rotational misfit.     

Risk of imbalance in elderly people with impaired hearing or vision

We evaluated the effect of impaired hearing and vision on balance in a sample of 977 elderly people residing in the community. Of the sample, 21% reported balance problems, 27% vision problems, and 30% hearing problems. The increased relative risk for balance problems was 1.7 for each 10-year age increment. Women were 1.7 times more likely to report balance problems than were men. The relative risk of imbalance with impaired vision decreased with age from 2.8 in those aged 65-69 years to 1.0 in those over 85 years. There was no age-hearing interaction, the relative risk for impaired hearing is 1.6. It appears that impaired vision and hearing are important risk factors for imbalance and perhaps falls and injury.     

The colitis of Behcet's disease: A separate entity?

Summary An additional case of Behcet's disease with colonic involvement has been presented. This association is rare, as only 13 prior cases with adequate data were available for comparison. Controversy exists as to whether these cases represented true involvement of the colon by Behcet's disease, coincidental inflammatory bowel disease and Behcet's disease, or merely autoimmune phenomena associated with inflammatory bowel disease. Unusual colonoscopic lesions noted in our patient and other features enumerated in the text suggested to us that at least some of these cases represented primary Behcet's disease involving the colon.     

Chronic conditions policies: oral health,a felt absence

The global health scenario shows an epidemic of non‐communicable diseases that lead to long‐term chronic conditions, some of which are incurable. Many infectious diseases, owing to their development and length, also generate chronic conditions. Similarly, non‐morbid states, such as pregnancy, and some life cycles such as adolescence and ageing, follow the same logic. Among all these chronic conditions there is a significant interrelationship with oral health, both in parallel events and common risk factors. This article presents cross‐sectional qualitative research into World Health Organisation recommended health policies to address chronic conditions. Several documents published by the organisation were analysed to verify the presence of references to oral health in relation to chronic conditions, particularly cardiovascular diseases and diabetes as these most frequently have oral manifestations. The analysis showed no significant references to oral health or its indicators within the published texts. The study recognises the value of the work developed by the World Health Organisation, as well as its worldwide leadership role in the development of health policies for chronic conditions. This article proposes a coalition of dentistry organisations that could, in a more forceful and collective way, advocate for a greater presence of oral health in drafting policies addressing chronic conditions.     

Take-home lead poisoning in a child from his father's occupational exposure

With the publication of revised CDC guidelines in 1991, concern about childhood lead poisoning has increased. Exposure to lead-based paint and paint dust is currently considered the major source of lead poisoning in the United States. We describe a child who had elevated BLL related to lead-contaminated clothing that the father brought home from his workplace. © 1996 Wiley-Liss, Inc.     

Interscalene anesthesia for shoulder arthroscopy in a community-sized military hospital

The first 100 consecutive shoulder arthroscopic procedures performed under interscalene anesthesia at a small community-sized military hospital are the basis of this report. This method of anesthesia was compared with 100 shoulder arthroscopies performed in a previous 2-year time period under general anesthesia. A variety of arthroscopic and subsequent open reconstructive procedures about the shoulder were performed using both techniques. Using the interscalene method, 87 regional blocks were entirely successful. Thirteen patients required conversion to general anesthesia for adequate pain control; however, 4 of these had a complete block in the recovery room and required no postoperative narcotics. Seven patients required supplementation with local anesthetic when an open procedure became necessary. There were no major complications. Minor complications included 5 patients with transient Horner's syndrome, 4 patients who experienced anxiety, which was controlled with sedation, and 3 with nausea or pruritus. Interscalene anesthesia provided excellent intraoperative and postoperative analgesia with low morbidity. On a subsequent questionnaire, all patients with a successful block reported that they were extremely satisfied with their experience. Ten patients who had previous shoulder surgery under general anesthesia preferred the interscalene method. In summary, interscalene anesthesia proved to be an excellent method of anesthesia for shoulder arthroscopy. The technique is reproducible within the resources available in most community-level hospitals.
