Selected AbstractsHealing Patterns Revealed in Middle School Boys' Experiences of Being Bullied Using Roger's Science of Unitary Human Beings (SUHB)JOURNAL OF CHILD AND ADOLESCENT PSYCHIATRIC NURSING, Issue 3 2010Danny G. Willis DNS, PMHCNS-BC PROBLEM:, Although two of the primary risk factors for being bullied include "male" and "middle school" status, a gap in knowledge exists of middle school boys' personal accounts and meanings of being bullied and their healing. METHODS:, Giorgi's descriptive phenomenological approach using open-ended semi-structured individual interviews was used to collect and analyze evidence related to middle school boys' lived experiences of being bullied and healing. Roger's Science of Unitary Human Beings (SUHB) guided interpretation of the healing patterns. FINDINGS:, Three patterns of healing were identified in boys' experiences: meaning-making, self-transcendence, and nonviolently claiming personal power. CONCLUSIONS:, Evidence of healing patterns exists in middle school boys' experiences of being bullied, offering a foundation for further research and practice focused on healing. When working with middle school boys who have been bullied, nurses need to ask about their experiences and promote their healing. [source] Healing patterns in calvarial bone defects following guided bone regeneration in ratsJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 9 2002A micro-CT scan analysis Abstract Objective: The objective of this study was to evaluate healing patterns of critical-size calvarial bone defects treated according to principles of guided bone regeneration using micro-CT scan analysis. Specifically, the contribution of bone, periosteum and dura mater to the amount and mineralization of newly formed bone was evaluated. Material and Methods: Surgically induced, critical-size calvarial bone defects in 48 adult male Wistar rats received the following: an occlusive expanded polytetrafluoroethylene (ePTFE) membrane at the exo- and endocranial aspect (OO; n = 12); an occlusive membrane at the exocranial and a perforated membrane at the endocranial aspect (OP; n = 12); a perforated membrane at the exocranial and an occlusive membrane at the endocranial aspect (PO; n = 12); and a perforated membrane at the exo- and endocranial aspect (PP; n = 12). The animals were euthanized at 4 weeks for quantitative analysis of bone volume fraction and mineralization in the region of interest (ROI) as well as in the external, middle and central area of the defect using micro-CT. Results: Bone volume fraction ranged from 31.4% (OP) to 24.5% (PP). No differences were found among the groups. Bone volume fraction and mineralization in the middle area were significantly greater in group OP than in group PP, and in the central area in group OO and PO than in group PP. Conclusions: The results of this study suggest that use of occlusive ePTFE membranes enhances bone formation and maturation in the calvarial skeleton. When occlusion of endo- and exocranial tissues was compromised by membrane perforation, impaired bone formation and mineralization were observed. [source] Recurrent trauma histories of two ,unlucky teeth': 42-month follow-upDENTAL TRAUMATOLOGY, Issue 5 2008Zuhal K The fracture type, severity of dislocation, mobility of fragments and diastasis have negative influence on the healing process. The aim of this study was to describe the treatment and the 42-month follow-up period of three trauma histories in a 12-year-old patient in 1 year and to emphasize the negative effects of recurrent traumas on the healing pattern and prognosis of root fractures. [source] Healing of 400 intra-alveolar root fractures.DENTAL TRAUMATOLOGY, Issue 4 2004Abstract,,, This is the second part of a retrospective study of 400 root-fractured permanent incisors. In this article, the effect of various treatment procedures is analyzed. Treatment delay, i.e. treatment later than 24 h after injury, did not change the root fracture healing pattern, healing with hard tissue between fragments (HH1), interposition of bone and/or periodontal ligament (PDL) or pulp necrosis (NEC). When initial displacement did not exceed 1 mm, optimal repositioning appeared to significantly enhance both the likelihood of pulpal healing and hard tissue repair (HH1). Significant differences in healing were found among the different splinting techniques. The lowest frequency of healing was found with cap splints and the highest with fiberglass or KevlarŪ splints. The latter splinting procedure showed almost the same healing result as non-splinting. Comparison between non-splinting and splinting for non-displaced teeth was found to reveal no benefit from splinting. With respect to root fractures with displacement, too few cases were available for analysis. No beneficial effect of splinting periods greater than 4 weeks could be demonstrated. The administration of antibiotics had the paradoxical effect of promoting both HH1 and NEC. No explanation could be found. It was concluded that, optimal repositioning seems to favor healing. Furthermore, the chosen splinting method appears to be related to healing of root fractures, with a preference to pulp healing and healing fusion of fragments to a certain flexibility of the splint and possibly also non-traumatogenic splint application. Splinting for more than 4 weeks was not found to influence the healing pattern. A certain treatment delay (a few days) appears not to result in inferior healing. The role of antibiotics upon fracture healing is questionable. [source] Differential cytokine activity and morphology during wound healing in the neonatal and adult rat skinJOURNAL OF CELLULAR AND MOLECULAR MEDICINE, Issue 6 2007W. Wagner Abstract Wound-healing mechanisms change during transition from prenatal to postnatal stage. Cytokines are known to play a key role in this process. The current study investigated the differential cytokine activity and healing morphology during healing of incisional skin wounds in rats of the ages neonatal (p0), 3 days old (p3) and adult, after six different healing times (2 hrs to 30 days). All seven tested cytokines (Transforming Growth Factor (TGF) ,, TGF,1, ,,2 and ,,3, IGF 1, Platelet Derived Growth Factor A (PDGF A), basic Fibroblast Growth Factor (bFGF) exhibited higher expression in the adult wounds than at the ages p0 and p3. Expression typically peaked between 12 hrs and 3 days post-wounding, and was not detectable any more at days 10 and 30. The neonate specimen showed more rapid re-epithelialization, far less inflammation and scarring, and larger restitution of original tissue architecture than their adult counterparts, resembling a prenatal healing pattern. The results may encourage the use of neonatal rat skin as a wound-healing model for further studies, instead of the more complicated prenatal animal models. Secondly, the data may recommend inhibition of PDGF A, basic FGF or TGF-,1 as therapeutic targets in efforts to optimize wound healing in the adult organism. [source] Immediate implants at fresh extraction sockets: bone healing in four different implant systemsJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 8 2009Massimo De Sanctis Abstract Objectives: To describe the differences in bone healing, when placing four different implant systems in fresh extraction sockets. Material and Methods: Eight beagle dogs received implants randomly installed into the distal socket of three P3 and four P4. Four-implant systems were evaluated. Each animal provided four test implant sites. All animals were sacrificed at 6 weeks after implant placement, providing specimens for histo-morphometric analysis of bone to implant contact (BIC), bone area, new bone formation, as well as histometric measurements of the ridge alterations. Results: No statistically significant difference was observed among the four-implant systems. The mean BIC % ranged between 58.5% and 72.1%. Bone modelling of the buccal plate was marked and amounted approximately to 2.5 mm, independently of the system used. Conclusion: This study failed to demonstrate differences in the healing pattern after 6 weeks when placing four different implant systems in fresh extraction sockets. In spite of achieving predictable osteointegration with the four implants studied, the occurrence of buccal bone resorption may limit the use of this surgical approach. [source] Post-pathological keel-loss compensation in ammonoid growthLETHAIA, Issue 1 2002ALAIN MORARD Among the various pathologies documented in ammonoids, impairs affecting the apertural margin may have long-lasting sequelae on subsequent shell geometry. An interesting healing pattern, known as sculptural compensation, led to the permanent replacement of an ornament by adjacent sculptural elements. Moreover, in several ventrally impaired individuals the symmetry was preserved. Those developed annular ribs in place of any previous ventral ornamentation (keel, sulcus or smooth area). This phenomenon is known from diverse ammonite families. Monestieria resouchei (Monestier 1931), type species of ,Monestieriinae' Sapunov 1965, displays exactly that type of annularly-ribbed morphology and has been shown to be otherwise similar to species of Grammoceratinae Buckman 1904 occurring in the same beds, thus corroborating its pathological nature and leading to the rejection of that taxon. Now, keel absence in Praehaploceras Monestier 1931 and Buckmanites Guex 1973 cannot be explained by the same process as they do not have annular ribs. Moreover, the absence of any clue of malformation, their relative frequency and specific characteristics exclude the previously suggested synonymies with Pseudolioceras Buckman 1889 as equivalent pathological forms. In consequence, their rehabilitation is herein proposed. They should be included within Harpoceratinae Neumayr 1875. [source] Ventilation Time of the Middle Ear in Otitis Media With Effusion (OME) After CO2 Laser MyringotomyTHE LARYNGOSCOPE, Issue 4 2002Benedikt Sedlmaier MD Abstract Objective The aim of this study was to investigate the transtympanic ventilation time, the healing course of the tympanic membrane, the early and late complications, and the recurrence rate of otitis media with effusion (OME) within 6 months after CO2 laser myringotomy with the CO2 laser otoscope Otoscan. Study Design Prospective clinical study. Materials and Methods In this study, laser myringotomy was performed with the CO2 laser otoscope Otoscan in a patient population comprising 81 children (159 ears) with a history of otitis media with effusion (OME) associated with adenoidal and sometimes tonsillar hyperplasia. The procedure on the tympanic membrane was accordingly combined with an adenoidectomy, a CO2 laser tonsillotomy, or a tonsillectomy and therefore performed under insufflation anesthesia. In all ears, approximately 2 mm circular perforations were created in the lower anterior quadrants with a power of 12 to 15 W, a pulse duration of 180 msec, and a scanned area of 2.2 mm in diameter. Results None of the children showed postoperative impairment of cochleovestibular function such as sensorineural hearing loss or nystagmus. Otomicroscopic and videoendoscopic monitoring documented the closure time and healing pattern of tympanic membrane perforations. The mean closure time was found to be 16.35 days (minimum, 8 days; maximum, 34 days). As a rule, an onion-skin-like membrane of keratinized material was seen in the former myringotomy perforations at the time of closure. At the follow-up 6 months later, the condition of the tympanic membrane of 129 ears (81.1%) could be checked by otomicroscopy and videoendoscopy and the hearing ability by audiometry and tympanometry. The CO2 laser myringotomy sites appeared normal and irritation-free. Two of the tympanic membranes examined (1.6%) showed atrophic scar formation, and 1 (0.8%) had a perforation with a diameter of 0.3 mm. The perforation was seen closed in a control otoscopy 15 months postoperatively. OME recurred in 26.3% of the ears seen intraoperatively with mucous secretion (n = 38) and in 13.5% of the ears with serous secretion (n = 37;P <.05). Conclusion The most important principle in treating OME is ventilation of the tympanic cavity. CO2 laser myringotomy achieves this through a self-healing perforation in which its diameter roughly determines the duration of transtympanic ventilation. Laser myringotomy competes with ventilation tube insertion in the treatment of OME. It may be a useful alternative in the surgical management of secretory otitis media.

[source] A comparison between immediate loading and immediate restoration in cases of partial posterior mandibular edentulism: a 3-year randomized clinical trialCLINICAL ORAL IMPLANTS RESEARCH, Issue 7 2010Marco Degidi Abstract Objective: The aim of this study was to compare the survival rate, the bone loss and soft-tissue healing patterns of immediately loaded and immediately restored implants in cases of partial posterior mandibular edentulism. Material and methods: Fifty patients with partial posterior mandibular edentulism were randomly selected for two treatments: 25 were included in the immediate loading group (test) and 25 in the immediate restoration group (control). All implants were placed in healed sites with a torque of >25 N cm. The temporary prosthesis of the immediate restoration group was placed so as to avoid occlusal contact in centric and lateral excursions. Both groups received fully occluding final restorations 6 months after surgery. Mean marginal bone loss was assessed at 6-, 12-, 24- and 36-month follow-up examinations by a blinded examiner. Results: A total of 100 implants were placed in the period between February 2004 and October 2006, of which 42 (42%) were for men and 58 (58%) for women. Five and 7 weeks after surgery, mobility of one implant was assessed in one (4%) patient in the test group and one (4%) patient in the control group, respectively. At the 36-month follow-up, the accumulated mean marginal bone loss was 0.987 mm (SD=0.375) for the immediate restoration group (n=48) and 0.947 mm (SD=0.323) for the immediate loading group (n=48). There was no statistically significant difference (P>0.05) for the tested outcome measures between the two procedures. Conclusions: This study was unable to detect any statistically significant difference in the survival rate, bone loss and soft tissue healing patterns between the immediately loaded and the immediately restored implants in cases of partial posterior mandibular edentulism. The immediate temporary rehabilitation of the partially edentulous posterior mandible is a predictable procedure using both procedures. To cite this article: Degidi M, Nardi D, Piattelli A.
