Pancreaticopleural fistula: Report of two cases and review of literature
Authors: Ranjan Piyush , Bansal Rinkesh , Sachdeva Munish , Kumar Mandhir
Published: May 2014

Pancreaticopleural fistula is a rare clinical problem. It is seen rarely in acute and chronic pancreatitis or after pancreatic duct trauma. It poses a diagnostic challenge. It may be silent or can present with predominant chest or abdominal symptoms. The diagnosis should be suspected if a patient presents with pleural effusion in a setting of pancreatitis or alcohol intake. The significantly raised amylase in the pleural fluid offers an important clue to the diagnosis. Computed tomography is the initial imaging of choice, which defines the pancreatic as well as chest abnormalities. The therapeutic options include medical, endoscopic, as well as surgical interventions. Although, there is no data comparing the endoscopic and surgical interventions, patients are generally treated with medical and endoscopic therapies. Surgery is reserved for those who fail medical and endoscopic therapies. Here we report two cases of pancreaticopleural fistulas that were treated successfully by endoscopic retrograde cholangiopancreatography and placement of a plastic stent in the main pancreatic duct.

Authors: Fluch Martin G. , Leary Ian J.
Published: May 2014

In dimension 3 and above, Bredon cohomology gives an accurate purely algebraic description of the minimal dimension of the classifying space for actions of a group with stabilisers in any given family of subgroups. For some Coxeter groups and the family of virtually cyclic subgroups we show that the Bredon cohomological dimension is 2 while the Bredon geometric dimension is 3.

Published: May 2014

Although malnutrition and malaria co-occur among individuals and populations globally, effects of nutritional status on risk for parasitemia and clinical illness remain poorly understood. We investigated associations between Plasmodium falciparum infection, nutrition, and food security in a cross-sectional survey of 365 Batwa pygmies in Kanungu District, Uganda in January of 2013. We identified 4.1% parasite prevalence among individuals over 5 years old. Severe food insecurity was associated with increased risk for positive rapid immunochromatographic test outcome (adjusted relative risk [ARR] = 13.09; 95% confidence interval [95% CI] = 2.23–76.79). High age/sex-adjusted mid-upper arm circumference was associated with decreased risk for positive test among individuals who were not severely food-insecure (ARR = 0.37; 95% CI = 0.19–0.69). Within Batwa pygmy communities, where malnutrition and food insecurity are common, individuals who are particularly undernourished or severely food-insecure may have elevated risk for P. falciparum parasitemia. This finding may motivate integrated control of malaria and malnutrition in low-transmission settings.
The Development of an Authentic Professional Identity on Role-Emerging Placements
Authors: Clarke Channine , Martin Marion , Sadlo Gaynor , de-Visser Richard
Published: May 2014

Introduction:

Role-emerging placements are increasingly used to help occupational therapy students develop the skills, knowledge, and attributes needed to become the therapists of tomorrow. Whilst literature on role-emerging placements is growing, studies have tended to be general placement evaluations, with only a limited number exploring students' experiences in detail.

Method:

This study used interpretative phenomenological analysis to gain a deeper understanding of how five MSc pre-registration occupational therapy students experienced and ascribed meaning to their role-emerging placements.

Findings:

The role-emerging placements acted as a strong catalyst for the students' ontological development (that is, their understanding of self and development of ways of being and enacting occupational therapy practice). Through engaging in challenging and autonomous learning experiences, students developed deeper insights into who they were becoming as professionals, leading to a professional identity of their own making.

Conclusion:

Having to continually reflect on and verbalize the core essence and contribution of occupational therapy, students developed clarity of understanding about the uniqueness of the profession. This is important in light of the historical difficulty occupational therapists have had in articulating their unique role and professional identity.
Enabling Occupational Therapy: Moving beyond the Generalist vs Specialist Debate in Community Mental Health
Authors: Michetti Jennifer , Dieleman Crystal
Published: May 2014

Occupational therapists working in community mental health teams continue to debate their role within a case management model of service. They are caught between a service system, requiring them to work as generalist care coordinators, and a profession working to distinguish itself in a multi-disciplinary context. This opinion piece moves beyond the debate of generalist/specialist roles to propose that occupational therapists can define their role and increase awareness of the profession's value by demonstrating leadership in everyday practice. The Leadership in Enabling Occupation Model is presented as a reflective tool for enabling occupational therapy contributions within community mental health care.
Home Safety for Children with Autistic Spectrum Disorder: Local Authority Occupational Therapy Intervention
Authors: Boyle Paul , Haines David , Lovelock Linda , Innes Kati
Published: May 2014

Introduction:

Health and social care agencies are encouraged to provide child-centred services that respond to needs that change over time. There is evidence that occupational therapists are concerned about how to respond to issues of harmful behaviour in the home environment whilst promoting child development. This study explored occupational therapists' experiences regarding harmful behaviour and the safety of children with Autistic Spectrum Disorder.

Method:

Seven community occupational therapists, employed by a local authority and working in social care, participated in two focus groups.

Findings:

An inductive thematic analysis identified five broad themes. These were: ‘assessment is complex’, ‘child development and the home environment’, ‘importance of family-centred services’, ‘the need for additional services’, and ‘management of the disabled facilities grant’.

Conclusion:

Local authority occupational therapists prioritize supporting families to keep children safe. It is necessary to adapt the home to reduce hazards and for alternative interventions to be made available to address behavioural and sensory needs. Services such as sensory integration are lacking, and where they are available access is difficult. It is common for disabled facilities grants to fund adaptations; however, management of grants could be improved to meet the needs of these children and their families.
Evaluating the Impact of Audits and Feedback as Methods for Implementation of Evidence in Stroke Rehabilitation
Authors: Kristensen Hanne , Hounsgaard Lise
Published: May 2014

Introduction:

This paper evaluates audits and feedback as methods to increase implementation of evidence in stroke rehabilitation.

Method:

The study used an action research approach and theories of knowledge translation. A sample of 22 occupational therapists participated from two Danish hospitals that admitted stroke patients. Data collection methods included audits of occupational therapy medical records, documentations of daily practice, and collaborative discussions. Active feedback and discussions of the findings took place, at a group level in four local clinical audits. Data analysis of daily self-reported recordings and audits was descriptive. Audit data were analysed using descriptive statistics. A phenomenological hermeneutical interpretive methodology was used for analysing qualitative data.

Findings:

Audits and feedback were based on clear standards and contextual developing action plans. Daily practice in both settings adapted to the clinical guidelines. Implementations of the standardized assessment tools seemed to be the most successful.

Conclusion:

The effects of audit and feedback profited from the active participation of the therapists, as well as local gatekeepers having formal responsibilities for implementing change. The process was strengthened by providing the audits and feedback more than once. The effect of audits and feedback was positively influenced by being in line with current conceptual frameworks, local policies, and values.

Authors: Borges Alvaro Henrique , Bandéca Matheus Coelho , Leite Fabio Renato Manzolli , Leite Amauri Antiquera , Sampaio José Eduardo Cezar , Pinto Shelon Cristina Souza , Fontanari Lucas Amaral , Cavassim Rodrigo
Published: May 2014

This study analyzes the clot stabilization on root surfaces of teeth impregnated with cotinine and nicotine and the influence of the scaling in the adhesion of blood components, observing the influence of new exposition to nicotine and/or cotinine after scaling. Fifteen human teeth extracted due to periodontal disease of non-smokers patients were selected and manually scaled. Four dentin blocks were obtained from each tooth (n = 60). Samples received blood application or reimpregnation with nicotine and/or cotinine, depending on the groups. Group 1: PBS immersion + root scaling + blood; group 2: nicotine + root scaling + blood; group 3: nicotine + root scaling + nicotine reapplication + blood; group 4: cotinine + root scaling + blood; group 5: cotinine + root scaling + cotinine reapplication+ blood; group 6: nicotine and cotinine + root scaling + nicotine and cotinine + blood. Samples were kept in 2 ml of each substance for 24 hours. Each group received a blood drop and was analyzed by SEM. The higher amount of blood components was present in teeth exposed to cotinine and the groups submitted to scaling and blood application in comparison with groups that received reapplication of toxic substances after scaling. The greater toxic effect on root dentin surface was after the exposure to nicotine and cotinine. Results suggest that periodontal healing may be delayed in smokers due to the direct inhibition of clot stabilization on the root surface when nicotine and cotinine are present concomitantly.

In vitro Retention Loss of Attachment-retained Removable Partial Denture
Authors: Can Gülsen , Özmumcu Baransel , Altinci Pinar
Published: May 2014

Aim

To investigate the importance of attachment types on the retention loss of extracoronal attachment-retained removable partial dentures depending on the usage period.

Materials and methods

In order to observe the retention loss of 5 different attachments (OT Strategy, OT Strategy-metal protected, Vario-stud-snap and Vario-soft 3 and ERA-RV) over time, attachment-retained partial dentures representing Kennedy II mod. I case were placed in a custom-made, retention test machine. For each minute, eight separating and joining movements were performed and retention values (Newton) of the attachments were recorded by computer. The retention tests implemented in 540,1080 and 2160 cycles. The data were evaluated statistically according to the two-way ANOVA and Tukey parametrical tests.

Results

The slide type attachment providing the best retention force was observed to be the most worn out by this process (p < 0.01) while the ball type attachments, which typically have the lesser retention force, showed less retention loss (p < 0.01).

Conclusion

It can be concluded that the retention attributes of the attachment-retained dentures were affected by the specific type of precision attachment as well as the usage period.

Clinical significance

Precision attachments with ball-type plastic matrices may be recommended for the clinical use due to their retention stability over time.

Effect of Lycopene in the Treatment of Periodontal Disease: A Clinical Study
Authors: Belludi Sphoorthi Anup , Verma Shiras , Banthia Ruchi , Bhusari Prashanth , Parwani Simran , Kedia Sameer , Saiprasad SV
Published: May 2014

Purpose

Several epidemiologic studies have suggested a role of tomato products in decreasing the risk of the development of diseases related to oxidative stress (cancer and other chronic diseases). Oxidative stress may result in periodontal tissue damage either directly or indirectly. Lycopene, a powerful antioxidant and the main carotenoid in tomato products possesses the greatest quenching ability of singlet oxygen among the various carotenoids and is effective in protecting blood lymphocytes from NOO-radical damage. Hence, the aim of the present study is to compare the effect of systemically administered lycopene as an adjunct to scaling and root planing in patients with gingivitis and periodontitis.

Materials and methods

Twenty systemically healthy patients were involved in a randomized, double-blind, parallel study and based on their clinical signs were divided into two groups of mild to moderate periodontitis (A) and moderate gingivitis (B). The subjects under the groups A and B were randomly distributed between the two treatment groups: test group (n = 5), 4 mg lycopene/day for 2 weeks with oral prophylaxis (full mouth scaling and root planing (SRP) completed within 24 hours) and controls (n = 5), receiving only oral prophylaxis. Pre- and post-therapeutic periodontal parameters were evaluated.

Results

In group A, statistically significant improvement in CAL was reported in test group as compared to control group. In group B, the difference between pretreatment and post-treatment bleeding on probing scores was found to be statistically non-significant in both groups.

Conclusion

Results show that lycopene is a promising treatment modality as an adjunct to full mouth SRP of the oral cavity in patients with moderate periodontal disease.

Clinical significance

Modulation of the free radical production seems to be essential for the inhibition of tissue destruction, and treatment with antioxidants, like lycopene, which is the most potent among them will block the production of free ROS or its effects might prove to be therapeutically valuable.

Authors: Jalaluddin Md , Ahamed Shabeer , Khalid Imran , Moon Ninad , Shafi TK , Ali Fareedi Mukram
Published: May 2014

Background

Local delivery of antimicrobial agents provides higher concentration of the drug in the periodontal site for longer periods than systemically delivered methods. In the present study an attempt is made to know the efficacy of controlled local drug delivery of doxycycline as an adjunctive treatment in the management of chronic periodontitis.

Materials and methods

A total of 12 patients, diagnosed as Chronic Periodontitis in the age of 25 to 55 years, were selected of both the sexes in this study. They were divided into Experimental group consisted of 30 sites who received complete scaling and root planing (SRP) followed by placement of Atridox gel and control group consisted of 30 sites who received only SRP. Clinical parameters were recorded at, baseline, days 30, 90 and 180. Parameters were plaque index, gingival index, gingival bleeding index and microbial analysis, probing pocket depth and Clinical attachment level (CAL). The microbiological analysis was done at baseline visit and at 90th day. Probing pocket depth and CAL were recorded only on day 0 and 180th day.

Results

In 180 days study, both the groups exhibited a significant improvement in periodontal status. Significant gain in attachment level was observed in both the group. Between both the groups the clinical parameters in the experimental groups exhibited better results as compared to the control group. Both the groups exhibited significant reduction in the number of spirochetes.

Conclusion

Combination therapy of SRP and 10% DH gel demonstrated better results at all levels suggesting that this therapy can play a significant role as an adjunct to SRP in the management of chronic periodontitis.

Effects of Bimax and Segmental Surgeries for Correction of Bimaxillary Dentoalveolar Protrusion Class I on Soft Tissue Parameters: Upper lip Thickness and Curvature, Nasolabial Angle and Nasal Prominence
Authors: Rahpeyma Amin , Khajehahmadi Saeedeh
Published: May 2014

Aim

Results of this study can show if bimax surgery for posterior repositioning of maxilla and correction of BPCLI has priority to the currently used segmental orthognathic surgery or not.

Materials and methods

This study was done on 40 whiteskinned Iranian patients with bimaxillary dentoalveolar protrusion class I (BPCLI) who sought treatment for their deformity. In the first group, treatment includes segmental surgery for backward replacement of anterior segment of the upper and lower jaw. In the second group, treatment was bimax surgery, in which whole upper and lower jaw moved backward. Twenty patients were included in each group. For this purpose, we measured upper lip thickness (ULT, distance between LS and IA), nose prominence (NP, distance between nasal tip and the perpendicular line from upper lip vermilion on FHP), subsulcus depth (SSD, distance of SLS from this perpendicular line), SN to H line distance and finally, nasolabial angle (NLA) before and after surgery.

Results

In our study, 65% of patients were female and the mean of age was 27 (17-39) years old. The mean of SNA, SNB, ANB and INA in our patients were 81.7 ± 2.9, 78.8 ± 2.8, 4.50 ± 1.4 and 120 ± 8.7, respectively. All variables except SSD were analyzed with t-test to compare the results of two methods of surgery. Differences in the values of NP, NLA, SN to H line distance and ULT before and after segmental and bimax surgeries between before and after surgery were significant. After surgeries, ULT and the SN to H line distance reduced significantly, and NLA became corrected to its normal range (90-110).

Conclusion

The results of this study showed that bimax and segmental surgeries can effectively correct BPCLI. Because of possible dental and periodontal complications of segmental surgery, we highly recommend bimax surgery for treatment of BPCLI.

Authors: de Toledo Leonardo Renato , Chávez-Andrade Gisselle Moraima , Kuga Milton Carlos , Duarte Marco Antonio Hungaro , Keine Katia Cristina , Anna-Junior Arnaldo Sant , Só Marcus Vinicius Reis
Published: May 2014

Aim

This study investigated the flowability, setting time, pH, calcium release and bond strength of a MTA-based cement (MTA Fillapex®) compared to AH Plus and Sealapex.

Materials and methods

For the flowability test, the ISO 6876:2001 specification was utilized and for the setting time test, the ASTM C266-03 specification was utilized. For the pH and calcium release measurements, 10 samples were prepared for each group and analyzed for several different periods. For the push-out test, dentin disks were distributed into three groups, according to the cement utilized and into three subgroups, according to the root third (n = 10). After obturation, the specimens underwent push-out testing. The data were compared statistically using a significance level of 5%.

Results

The flowability of all materials was found to be similar (p > 0.05). The setting times were different among the groups tested (MTA Fillapex < Sealapex < AH Plus) (p < 0.05). At days 7 and 28, the MTA Fillapex presented the higher pH values (p < 0.05). At 24 hours and at 14 days, the calcium release of the MTA Fillapex was similar to that of Sealapex (p > 0.05). AH Plus presented the lowest pH and calcium release values (p < 0.05). In all root thirds, the adhesion to the dentin of the MTA Fillapex and Sealapex were significantly lower than that of AH Plus (p < 0.05).

Conclusion

MTA Fillapex and Sealapex presented several similar properties and both were found to be different than AH Plus.

Clinical significance

This study evaluated the physicochemical and mechanical properties of new MTA-based root canal cement, in order to use this scaler in root canal fillings. MTA Fillapex showed satisfactory properties for clinical use.

Authors: Reddy N Simhachalam , Narendra R , Reddy Sashi Deepth , Purna CR Sashi , Shekar M Chandra , Balasubramanyam S
Published: May 2014

The denture bases made by using polymethyl methacrylates of Acrylic resin family have excellent physical properties, simple to process and easy to reline, rebase and repair. One of the inherent disadvantages of this material is the liability to break during function. The strength assessment of acrylic resins have been made generally by transverse deflection tests.

Aim

To evaluate the impact strength valves of certain brands of commercially available denture base resins and suggest their suitability.

Materials and methods

The denture bases we made using polymethyl methacrylates of acrylic resin family because they have excellent physical properties, simple to process and easy to reline and rebase. Six commercial brands of polymethyl methacrylate, namely Stellon (DPI-India), Acralyn-H (Asian Acrylate, India), Trevalon (Dentsply-England), Lucitone 199 (Dentsply/ York division), Acralyn-H (Super Unbreakable), Trevalon HI (Dentsply, Detray division, England) were tested by breaking them using Analog Pendulum (ASTM D 256).

Results

From the entire study the maximum impact strength was reported for Acralyn-H super unbreakable (Asian Acrylates, India) 62.19 joules.

Conclusion

All the analysis led to conclusion that there is basic change in material composition within and among the different groups of denture base resins.

Clinical implications

The complete dentures made using denture base resins with high impact strength valves (e.g. Acralyn-H super unbreakable) will be more durable and can be used by the patient for considerable period of time, i.e. beyond 4 to 5 years.

Palatal Vault Depth Influence on the Flexural Strength of Two Heat Cure Acrylic Denture Base Resins: An in vitro Study
Authors: Reddy B Madan Mohan , Himabindu M , Padmaja B Indira , Sunil M , Reddy N Raja
Published: May 2014

Complete dentures often fracture during normal masticatory function. The reason could be due to the shape of the palate, i.e. deep, medium or shallow palatal vault. This in vitro study was performed to determine the relationship of palatal vault depth and flexural strength of two different permanent denture base resins. Edentulous maxillary casts of patients were collected from the department of prosthodontics, among these the cast with the deepest palatal vault was selected. The specimens were then subjected for flexural strength on universal testing machine. The results revealed that the denture bases fabricated on medium palatal vault depth were best in the flexural strength and denture bases on shallow palatal vault depth faired the least. Among the resins the denture bases fabricated using high impact heat cure resin, were better than the denture bases fabricated using regular heat cure resin. All these results were statistically significant except the results between the regular heat cure denture bases and high impact heat cure denture bases fabricated on the deep palatal vault depth. Also the comparison of fracture energies of denture bases fabricated on deep palatal vault with high impact heat cure resin to denture bases fabricated on medium and shallow palatal vaults with high impact heat cure resin were not significant. It was also observed that all the specimens have fractured in the midline.

Clinical implications

Palatal vault depth significantly affected the flexural strength of heat cure resin. The most frequent mechanical failure of heat cure resin is fracture especially at the midline. The denture bases fabricated using high impact heat cure resin had best flexural strength than the denture bases fabricated using regular heat cure resin which reduced the fractures.

Authors: Shet RGK , Yadav Rishi Dev , Rao Srinivasa , Patel Ruchi , Suvvati Priyalatha , Sadar Leena R
Published: May 2014

There is disagreement about the association between missing teeth and the presence of temporomandibular disorder (TMD).

Aim

To investigate whether, the span of edentulousness, gender, number of quadrants involved, pathological migration and the type of kennedy's classification are related to the temporomandibular joint (TMJ) dysfunction signs.

Materials and methods

Clinical examination of 250 patients (males 99 and females 151) was done among the age group of 35 to 45 years. The patients were partially edentulous for 6 months or more and did not wear any kind of prosthesis.

Results

Among 250 subjects, females showed more TMJ dysfunction signs. Clicking sounds were present in 46.5%, mandibular deviation was present in 40% of individuals, TMJ tenderness was observed in 32% and masseter was involved in 32% of individual. Temporomandibular joint dysfunction signs in relation to pathologic migration of teeth show that clicking and mandibular deviation was present in 54.5 and 49.2% and among muscles masseter muscle tenderness 41.9% was more commonly present. Masseter muscle tenderness 64.1% was seen in individuals who were edentulous for more than 5 years.

Conclusion

Females subjects had a significantly higher prevalence of TMJ dysfunction signs then male subjects. As the span and time of edentulousness, the number of missing teeth and the number of quadrant involved increased, the signs of dysfunction became more prevalent. Among the TMJ dysfunction signs deviation and clicking sound were most frequently observed. The masseter muscle was most commonly affected and demonstrated muscle tenderness.

Results

Nearly half of the subjects clean their dentures daily once. Participants from the younger age group and who had been wearing dentures since 2 years maintain better frequency of cleaning. The majority of these subjects used water and brush for denture cleansing. After seeing the condition, half of the dentures were rated as good 50.3%, followed by fair and poor as 29.5 and 20.2% respectively.

Clinical significance

Poor condition of complete dentures seen in the population is mainly due to irregularly cleansing habits and also less usage of cleansing solutions. Dentists should give proper instructions regarding maintenance of denture hygiene.

Authors: Reddy Ajay , Vasudevan Sanjay , Renuka J Valli , Sylvia D Sharon , Challa Radhika , Padmakanth M
Published: May 2014

Objectives

To determine and correlate the effect of clomiphene citrate, Letrozole in women undergoing infertility treatment on the gingival inflammatory status.

Materials and Methods

The present study is a randomized controlled clinical trial which consisted of 26 women using CC for three menstrual cycles, 26 women using CC for more than three cycles, 26 women using Letrozole. All subjects were clinically examined for plaque levels (Plaque Index), gingival inflammation, bleeding on probing (Gingival Index, Sulcus Bleeding Index). Scaling was done to all patients and all periodontal parameters were reassessed 1 month after scaling. The results were compared with a control group of 26 women matched for age, educational status and professional level, and oral habits and who had never used ovulation drugs.

Results

Baseline scores of all the test groups showed higher amount of plaque levels and inflammation compared to control. (p < 0.05). After scaling a significant reduction in inflammation was observed in all the test groups along with the control group (p < 0.0001), but women using the drugs showed persistence of inflammation compared to control (p < 0.01).

Conclusion

It can be concluded from the present study that the presence of elevated levels of hormones due to the effect of ovulation induction drugs may be the reason for the gingival inflammation in test groups.

The Relationship between prosthetic status and the Geriatric Oral Health Assessment Index in a Group of Institutionalized elderly of an Indian City: A cross-sectional study
Authors: Bijle Mohammed Nadeem Ahmed , Shetty Vittal Das
Published: May 2014

Aim

To assess and compare the quality of life and oral health status among institutionalized elderly in Pune.

Materials and methods

A cross-sectional, quantitative exploratory study was conducted in persons 60 years of age in an institutionalized elderly home. The GOHAI questionnaire was completed by a single examiner, who interviewed the patients in their local language. The oral examination was carried out according to WHO oral health survey using the DMFT-index, community periodontal index (CPI), periodontal loss of attachment (PLA), prosthetic use, and needs according to criteria established by the WHO by a calibrated examiner. Descriptive analysis was carried out using absolute and relative frequencies of the qualitative variables and means with respective standard deviations for the quantitative variables. The Student's t-test was applied to compare groups.

Results

Out of the total 110 individuals interviewed for the study, 64% were males and 36% were females. Individuals with up to 20 missing teeth and individuals with more than 20 missing teeth were 20 and 80% respectively. Based on the prosthetic need, 66% individuals needed replacement of teeth by dentures in one or both arches while 34% did not need any replacement by complete denture. The mean value for physical dimension was 5.40 whereas for psychosocial dimension, pain/discomfort and behavioral dimension were 8.02, 4.58 and 7.32.

Conclusion

The quality of life was found to be more favorable in individuals with less than 20 teeth missing. The quality of life among complete denture wearers in both the arches was better as compared to the quality of life among nondenture wearers. Prosthetic replacement by complete denture helps the individuals to maintain better oral health.

Clinical significance

The data obtained from the present study may serve as a reference point for comparisons of the magnitude of quality-of-life indicators relating to oral health.

Calcifying Odontogenic Cyst: A Rare Report of A Nonneoplastic Variant associated with Cholesterol Granuloma
Authors: Aparna Manikkath , Gupta Mukund , Kamath Abhay , Solomon Monica , Pai Keerthilatha , Radhakrishnan Raghu
Published: May 2014

Aim

To report a case of a non-neoplastic variant of calcifying odontogenic cyst (COC) with the lining epithelium showing ameloblastomatous proliferation and capsule exhibiting features of a cholesterol granuloma. The importance of delineating this histologic variant from unicystic ameloblastoma and the formation of cholesterol granuloma in this variant is discussed.

Background

Calcifying odontogenic cyst is a developmental jaw cyst, which presents itself as both the neoplastic and the non-neoplastic forms. The ameloblastomatous variant of COC is often mistaken for unicystic ameloblastoma and treated aggressively.

Case report

A 68-year-old female who presented with a cystic enlargement of the posterior mandible on the right side was suggestive of unicystic ameloblastoma based on radiography and initial biopsy report. Microscopic examination of the excision specimen, however, was fitting in favor of calcifying odontogenic cyst with ameloblastomatous proliferation.

Conclusion

Identifying the non-neoplastic ameloblastomatous variant of COC from a cystic ameloblastoma is crucial as the treatment of the two lesions vary considerably.

Clinical significance

This case emphasizes the need for thorough examination of the entire surgical specimen before arriving at an appropriate diagnosis.

C-Arm Fluoroscopy: A Reliable Modality for Retrieval of Foreign Bodies in the Maxillofacial Region
Authors: Pandyan Deepak , Nandakumar N , Qayyumi Burhanuddin N
Published: May 2014

The anatomic complexity of the maxillofacial region makes the retrieval of foreign bodies a daunting task for the maxillofacial Surgeon. Moreover the inability of 2-dimensional imaging to precisely locate foreign bodies makes it challenging. The anatomic proximity of critical structures and esthetic considerations limits the access and thus poses a greater challenge for the surgeon in cases of foreign body retrieval. Hereby we propose a simple technique and a case report to support, the retrieval of small (<5 mm greatest dimension) objects from the maxillofacial region. The present technique uses a 2 dimensional mobile C arm Fluoroscopy and a needle triangulation method to precisely locate a loosened miniplate screw in the mandibular angle region.

Can the Use of Antibiotics interfere with the Success of Dental Osseointegrated Implants in Diabetic Patients?
Authors: Borba Alexandre Meireles , Souza Daniel Falbo Martins , Brozoski Mariana Aparecida , Burim Rafael Augusto , Naclério-Homem Maria da Graça , Deboni Maria Cristina Zindel
Published: May 2014

Aim

The present review aims to discuss the last 10 years published data on the topic of the use of osseointegrated implants in diabetic subjects, particularly regarding the influence of antibiotics administration in the perioperative period.

Background

In the last decades, oral rehabilitation significantly has evolved particularly with the use of osseointegrated implants. Increased life expectation of population is reflecting in a greater number of diabetic patients who might require dental osseointegrated implants rehabilitation. Diabetes was considered for a long time as a contraindication for oral implant placement. In this context, the use of antibiotics is still a controversial factor when we correlate it to implant success rate.

Review results

Although 228 articles were initially selected for evaluation of proposed criteria, only 16 articles were considered valid. Among the 16 selected articles, only six articles represented clinical research that discussed the influence of the antibiotic in the success of osseointegration of dental implants in diabetic subjects. Five were retrospective studies and one a prospective research.

Conclusion

Data favors the use of antibiotics without significant side effects but clinical investigations of the need of prophylaxis antibiotic or therapeutic antibiotics are still scarce. The lack of adequate methodology is one of the main problems of the current articles. It is important to emphasize that studies should present detailed methodology in order to allow reproducibility.

Clinical significance

Permanent tooth loss is a pathological condition that affects millions of people worldwide. The possibility of successful treatment of edentulous areas through osseointegrated implants in those systemic compromised patients is a matter of scientific discussion. Although antimicrobial agents must be used rationally and carefully to avoid development of bacterial resistance, more studies are needed in order to support evidence regarding the influence of antibiotics in the success of dental implant surgery in diabetic patients.

Just ‘a little UN Committee’ or important policy driver? - The impact and effectiveness of the CEDAW Committee in New Zealand
Authors: Krommendijk Jasper
Published: May 2014

This article examines the impact and effectiveness of the process of state reporting under CEDAW in New Zealand. The particular focus is on the effectiveness of the Concluding Observations (COs) of the Committee on the Elimination of All Forms of Discrimination against Women (CEDAW Committee). It concludes that the COs of the CEDAW Committee have not driven policy or legislative changes. This is attributed to the absence of domestic mobilisation in relation to the process of reporting and CEDAW in general, but also to the limited legitimacy and persuasiveness of the CEDAW Committee in the view of Government officials. The experience with several of the COs of the Children’s Rights Committee in New Zealand and some of the COs of the CEDAW Committee in the Netherlands, however, illustrates that COs can be useful. COs can provide additional legitimacy to the demands of domestic actors advocating for change and can, hence, push an issue forward by shifting the terms of the debate.
The Uses and Abuses of Gender
Authors: Scott Joan W.
Published: May 2014

In the summer of 2011 a violent debate erupted in France over the meaning of the term gender. Catholics, parents and educators protested against a manual for biology students deemed to promote a ‘theory of gender’ that might endanger social order and corrupt young adults. The author traces the emergence of gender as a site for political strife in various context. As such the term seems to have replaced the term ‘women’ as a rallying cry for the mobilization of feminists. Gender has not only been a useful concept for feminist researchers and activists, Scott argues, but it has also been used in international politics. In the context of UN committees for policies on women, gender is used to plead for as well as against feminist policies. In addition to being used as an analytical concept, gender has become a contested political concept.
