Authors: Wu JiaQi , Jiang Jiu-Hui , Xu Li , Liang Cheng , Bai YunYang , Zou Wei 
Published: October 2014

ABSTRACT

Objective:
To evaluate if the improved accelerated osteogenic orthodontics (IAOO) procedure could speed Class III surgical patients' preoperative orthodontic treatment duration and, if yes, to what extent. This study was also designed to determine whether or not an IAOO procedure affects the tooth-moving pattern during extraction space closure.

Materials and Methods:
The samples in this study consisted of 24 Class III surgical patients. Twelve skeletal Class III surgery patients served as an experimental group (group 1) and the others as a control group (group 2). Before treatment, the maxillary first premolars were removed. For group 1, after the maxillary dental arch was aligned and leveled (T2), IAOO procedures were performed in the maxillary alveolar bone. Except for this IAOO procedure in group 1, all 24 patients experienced similar combined orthodontic and orthognathic treatment. Study casts of the maxillary dentitions were made before orthodontic treatment (T1) and after extraction space closure (T3). All of the casts were laser scanned, and the amount of movement of the maxillary central incisor, canine, and first molar, as well as arch widths, were digitally measured and analyzed by using the three-dimensional model superimposition method.

Results:
The time durations T3–T2 were significantly reduced in group 1 by 8.65 ± 2.67 months and for T3–T1 were reduced by 6.39 ± 2.00 months (P &lt; .001). Meanwhile, the tooth movement rates were all higher in group 1 (P &lt; .05). There were no significant differences in the amount of teeth movement in the sagittal, vertical, and transverse dimensions between the two groups (P &gt; .05).

Conclusion:
The IAOO can reduce the surgical orthodontic treatment time for the skeletal Class III surgical patient by more than half a year on average. The IAOO procedures do not save anchorage.
Correlation between objective and subjective evaluation of profile in bimaxillary protrusion patients after orthodontic treatment
Authors: Huang Yi-Ping , Li Wei-ran 
Published: October 2014

ABSTRACT

Objective:
To correlate the objective cephalometric measurements with subjective facial esthetics in patients with bimaxillary protrusion.

Materials and Methods:
The sample consisted of 60 Asian-Chinese patients with bimaxillary protrusion who met the inclusion criteria. The facial esthetics of posttreatment profile and the change of profile on standardized lateral photographs were rated by a panel of 10 orthodontists and a panel of 10 lay persons with bimaxillary protrusion. All of the pretreatment and posttreatment cephalograms were digitized and traced. Twenty-five cephalometric measurements were constructed and analyzed. Correlations between the subjective facial esthetic scores and each cephalometric measurement were evaluated.

Results:
The cephalometric measurements correlated with the facial esthetic scores of posttreatment profile given by the orthodontist and the lay persons were basically the same. For the evaluation of posttreatment profile in bimaxillary protrusion patients, the upper and lower lip to E-line, upper and lower incisor tip to AP plane, Pg-NB distance, mentolabial angle, and sulcus depth correlated significantly with the esthetic score. For the evaluation of profile change during orthodontic treatment, retraction of upper incisor relative to AP plane or the perpendicular line through sella (line Y), change of upper incisor inclination, change of mentolabial sulcus depth, and retraction of lips relative to E-line were correlated positively with the esthetic value.

Conclusions:
Cephalometric measurements of lip position, incisor position, and chin morphology were key parameters correlated to facial esthetics.
Expressives and Expressivity
Authors: McCready Eric 
Published: October 2014

AbstractThis paper considers the questions of translatability and expressive power. It is argued that truthconditional content is always translatable, and does not produce differences in expressive power. Most nontruth- conditional content—presupposition, ‘side effects’ such as anaphora, and conventional implicature—is shown to not always translate successfully, but still not to produce genuine differences in expressivity. This last property appears to clearly hold only of terms which introduce expressive content: only for such content is genuine incommensurability found in natural language. Some implications of these findings are discussed.

Evaluation of the Reliability of Hamular Notch-Incisive Papilla Plane (HIP) in Establishing Occlusal Plane
Authors: Thapa Dipak 
Published: October 2014

Introduction: There are various recommendations, using both soft tissue and hard tissue landmarks, for the determination ofocclusal plane in dentistry. However, their reliability and accuracy has always been questioned. Hamular notch-Incisive papillaPlane (HIP) is one of such landmarks which is stated to be parallel to occlusal plane; however its reliability needs to be evaluated.Objective: To find the relationship between hamular notch-incisive papilla plane and occlusal plane in dentulous subjects.Materials & Method: 48 dentate subjects with normal Class I occlusion participated in the study. Their maxillary impressionswere made and casts were poured. Each cast was then mounted in the surveyor and HIP plane made parallel to the floorby tripoding method. With the cast in this relation, the vertical distance between HIP and various reference points of occlusalplanes were measured using digital Vernier Caliper. Wilcoxon test was used to find the statistical difference (p<0.05).Result: During evaluation of data, none of the cast showed absolute parallelism between occlusal plane and HIP plane. Themean vertical distance between HIP and incisal edge (INC) was 6.44 mm, whereas between HIP-6RMP and HIP-6LMP were6.41 mm and 6.12 mm respectively. About 81% cases showed parallelism within the range of 2 mm. 2-related sample statistic testshowed no statistically difference (p<0.05) between HIP-INC and HIP-6RMP; and HIP-INC and HIP-6LMP.Conclusion: HIP plane tends to be parallel to occlusal plane and can be used as a clinical guideline in the determination ofinclination of the occlusal plane.DOI: http://dx.doi.org/10.3126/ojn.v4i1.11311 Orthodontic Journal of Nepal Vol.4(1) 2014; 45-47
Pollinator‐mediated competition influences selection for flower‐color displacement in sympatric monkeyflowers
Authors: Grossenbacher Dena L. , Stanton Maureen L. 
Published: October 2014

•Premise of study:When coflowering plant species share pollinators, pollinator‐mediated competition may favor divergent floral characters associated with pollinator attraction. One potential outcome of this process is that sympatric populations will display increased divergence in floral traits compared with allopatric populations. We developed a new system to study the pattern and process of character displacement. In the central Sierra Nevada of California, USA,Mimulus bicoloris a spring wildflower with two flower‐color morphs, one of which resembles cofloweringM. guttatus.•Methods:We documented a fine‐scale geographic pattern of character displacement in sympatric and allopatric patches and, using experimental arrays, measured seed set inM. bicolorcolor morphs in the presence versus absence ofM. guttatus.•Key results:In sympatric arrays yellow,guttatus‐likeM. bicolormorphs had lower relative fitness (0.35 ± 0.05) and reduced conspecific pollen deposition compared with the distinct alternative morph, whereas in allopatric arrays yellow,guttatus‐like morphs were occasionally strongly favored.•Conclusions:Pollinator‐mediated competition withM. guttatusis consistent with ecological character displacement inM. bicolorand likely contributes to a geographic pattern of character displacement.
Remnants of populations provide effective source material for reintroduction of an endangered Hawaiian plant, Schiedea kaalae (Caryophyllaceae)
Authors: Weisenberger Lauren A. , Weller Stephen G. , Sakai Ann K. 
Published: October 2014

• Premise of the study: Reintroductions may be essential to prevent extinction of many critically endangered species. Ideally, reintroduction efforts rely on adjacent source populations, but limited source material may necessitate crossing individuals from different and possibly distant populations. To determine the consequences of integrating multiple populations in reintroductions, we investigated levels of inbreeding depression, outbreeding depression, and heterosis for populations of Schiedea kaalae (Caryophyllaceae), an endangered species endemic to the Wai‘anae and Ko‘olau Mountains of O‘ahu, Hawai‘i. The possibility of gene flow among plants was explored through pollinator observations.• Methods: Individuals from ex situ living collections of nine populations were hand‐pollinated with pollen from the same plant, plants from the same population (for three populations only), or plants from different populations. Progeny were outplanted into two common gardens, one in each mountain range on O‘ahu. Cumulative fitness was estimated using several independent life history stages.• Key results: Inbreeding depression was minimal, and no outbreeding depression was detected. In contrast, strong heterosis was evident in progeny from between‐population crosses, which had higher relative fitness than progeny from self‐pollinations or within‐population crosses. Observations of floral visitors provided the first evidence that biotic pollination may be important for this species.• Conclusions: Results demonstrate the ability to conduct genetic rescue of rare species and suggest that reintroductions may be most successful using heterotic individuals from crosses between populations and at sites where pollinators are present and promote outcrossing.

Background We explored the relationship between virological response in the first year of treatment and long-term outcomes in the BENCHMRK studies. Methods Patients failing antiretroviral treatment with 3-class resistant HIV-1 received double-blinded raltegravir (or placebo) with optimized background therapy (OBT) until week 156, followed by open-label raltegravir with OBT up to week 240. In this exploratory analysis of patients randomized to raltegravir, virological response over weeks 16–48 was categorized as continuous suppression (CS; viral RNA [vRNA] always <50 copies/ml), low-level viraemia (LLV; vRNA always <400 copies/ml, >50 copies/ml at least once), or not suppressed (NS; vRNA >400 copies/ml at least once). The association between these first-year vRNA response categories and baseline factors was analysed with univariate and multi-variate models. Virological and immunological outcomes for years 2–5 were assessed by first-year vRNA response category (observed failure approach). Results Baseline vRNA, baseline CD4+ T-cell count and rapid viral decay (vRNA <50 copies/ml between weeks 2–12) correlated with first-year vRNA response ( P<0.001); only rapid viral decay remained significant by multiple regression. Virological response rates were similar in the LLV and CS groups and lowest in the NS group. CD4+ T-cell count increased through week 240 in the CS and LLV groups. Time to loss of virological response (confirmed vRNA ≥400 copies/ml) through week 240 did not support as strong a difference between the LLV and CS groups (log-rank P=0.11) as previously reported through weeks 156 and 192 ( P<0.05). Conclusions Treatment-experienced patients on a raltegravir-based regimen with early LLV may have long-term virological and immunological benefit when their therapy is maintained.
Urgences thérapeutiques et éthiques dans la prise en charge de patients en soins palliatifs : utilité d'une fiche de transmissions médicales dans le cadre de l'organisation des soins de premiers recours

Published: October 2014

La prise en charge en urgence de patients en fin de vie nécessite de connaître précisément les vœux du patient. Bien que les soins palliatifs se développent depuis une vingtaine d’années en France, il n’existe pas a l’heure actuelle une fiche de transmissions médicales standardisée. Pour répondre à cette problématique ; nous avons mené une étude analytique descriptive a été menée à partir d’un questionnaire – élaboré en 2010 – interrogeant les médecins généralistes libéraux de Mayenne sur l’utilité d’une fiche de transmissions médicales – intitulée « SAMU urgences pallia 53 » – concernant les patients en soins palliatifs. L’étude montre que les médecins déclarent quasi unanimement cette fiche comme importante et utile. Plus de quatre-vingt pour cent des médecins déclarant être mal informés ont souhaité bénéficier d’une nouvelle formation à propos de cette fiche. Le faible taux de réponse ne permet pas de dresser des conclusions sur les pratiques médicales des médecins généralistes libéraux mais apporte des éléments utiles dans un domaine encore peu exploré. Le bilan à un an de la mise en place de la fiche SAMU urgences pallia 53 dans la Mayenne s’avérant positif, une étude sera menée incessamment afin d’évaluer la faisabilité de la mise en place de cet outil dans le département du Maine-et-Loire.
Découverte d'une anomalie génétique et information de la parentèle
Authors: Truchet Didier 
Published: October 2014

La possibilité de révéler l’existence d’une anomalie génétique par un simple examen médical renouvelle la problématique de la conciliation entre respect du secret médical et nécessité de protéger la santé d’autrui : le patient demandeur de l’examen n’est pas seul concerné par son résultat, sa famille l’est aussi. Didier Truchet analyse avec précision les droits et obligations de chacun – médecin ou patient – tels qu’ils ressortent de la loi du 7 juillet 2011.

Background:

A recommendation in the Institute of Medicine’s report,
The Future of Nursing: Leading Change, Advancing Health
, challenges the nursing profession to enhance nursing’s leadership role in health care redesign.

Method:
This descriptive, correlational, cross-sectional study examined the self-perceived leadership behaviors of RNs enrolled in a clinical ladder career pathway. A self-report survey was conducted using the Leadership Practice Inventory and a demographic questionnaire.

Results:
Significant associations between continuous and categorical demographic factors and ladder levels were reported. Nurses with more experience showed fewer leadership behaviors.

Conclusion:
Leadership development is necessary for nurses in all areas of practice. The findings from this study provide evidence of the strengths and weaknesses in leadership behaviors of staff clinical RNs who often make frontline decisions for patients.

CURRENT KNOWLEDGE ON HIV-ASSOCIATED PLASMABLASTIC LYMPHOMA
Authors: Bibas Michele , Castillo Jorge J 
Published: October 2014

HIV-associated PBL is an AIDS-defining cancer, classified by WHO as distinct entity of aggressive DLBCL. To date less than 250 cases have been published, of them17 are pediatric. The pathogenesis of this rare disease is related to immunodefiency, chronic immune stimulation and EBV. Clinically is a rapid growing destructive disease mainly of oral cavity, but frequently involves extraoral and extranodal sites. The diagnosis requires tissue mass or lymph node biopsy, but core needle or fine needle biopsy is acceptable for difficult access sites. Immunophenotype is CD45, CD20, CD79a negative and CD38, CD138, MUM1 positive, EBER and KI67 is >80%. Frequently is diagnosed in patients with low CD4+ and high viral load, however is reported also in patients on effective cART and high CD4. Treatment administered is usually CHOP or CHOP-like regimens, more intensive regimens as CODOX-M/IVAC or DA-EPOCH are possible options. Intensification with ABMT in CR1 may be considered for fit patients. Rituximab is not useful for this CD20- disease. Bortezomib and new drugs were used at case report level, with transient response. CNS prophylaxis is mandatory. Use of cART is recommended during chemotherapy, keeping in mind the possible overlapping toxicities. For refractory/relapsed patients, therapy is usually considered palliative, however in chemosensitive disease intensification + ABMT or new drugs may be considered. Factors affecting outcome are achieving complete remission, PS, clinical stage, MYC , IPI. Reported median PFS ranges between 6-7 months and median OS ranges between 11-13 months. Long term survivor are reported but mostly in pediatric patients. Due to the scarcity of data on this subtype of NHL we suggest that the diagnosis and the management of HIV-positive PBL patients should be performed in specialized centers.

Published: October 2014

ABSTRACT

Background
The effect of environmental allergy on laryngeal and pharyngeal complaints is not well understood. The goal of this study was to determine the prevalence of laryngeal and pharyngeal symptoms in patients with environmental inhalant allergy.

Methods
A retrospective review was conducted of all patients undergoing allergy skin testing between 2006 and 2009. Patients with positive skin tests were included and were classified as ‘mild’ or ‘extensive’ reactors based on skin testing results. Data regarding laryngeal and pharyngeal complaints, as well as ocular and nasal symptoms, had been systematically documented for all patients. The prevalence of these complaints was calculated in each group of reactors and overall.

Results
The prevalence of laryngeal and pharyngeal complaints was 42.0% overall, 45.5% among the mild reactors, and 39.3% in the extensive reactors. No patients complained of hoarseness or were felt to have dysphonia. There was no statistically significant difference between the mild and extensive reactors (p = 0.78). The prevalence of ocular and/or nasal symptoms was 96.0, 90.9 and 100%, respectively.

Conclusion
The prevalence of laryngeal and pharyngeal complaints in allergy sufferers was low in this study. Given the conflicting literature on this topic, there is insufficient evidence to establish a causal link between environmental allergy and laryngeal and pharyngeal symptoms.

Published: October 2014

ABSTRACT

Background
Spinal muscular atrophy is a rare autosomal recessive neurodegenerative disorder. We report a case of 62-year-old female of spinal muscular atrophy presenting with bilateral vocal fold paralysis, her diagnosis and management.

Objective
Case report of a case of spinal muscular atrophy presenting with bilateral vocal fold paralysis.

Conclusion
Spinomuscular atrophy though rarely associated with laryngeal symptoms should be kept in mind as a possible etiology of bilateral vocal fold paralysis. The surgical decision and the postoperative sequeale will be affected due to the presence of this disease and thus a high index of suspicion is required.

Near-total Laryngectomy: An Oncologically Safe Alternative
Authors: Verma Hitesh 
Published: October 2014

ABSTRACT
Traditional treatment for advanced transglottic laryngeal and hypopharyngeal cancers is wide field laryngectomy. Patients who undergo wide field laryngectomy must also undergo voice rehabilitation with a prosthesis, electrolarynx or esophageal speech. These are associated with complications, such as bloating of the stomach, stenosis, aspiration and difficulty with hygiene of the TEP prosthesis. Near-total laryngectomy is a surgical treatment modality, where speech is maintained by way of a dynamic myomucosal shunt. It was specially designed to overcome the serious complications of adynamic tracheoesophageal shunt methods.
