Exaggerating, mislabeling or simulating obsessive-compulsive symptoms: Case reports of patients claiming to have obsessive-compulsive disorder

Background: There are no reported cases of factitious or simulated obsessive compulsive disorder (OCD). However, over the last years, our clinic has come across a number of individuals that seem to exaggerate, mislabel or even intentionally produce obsessive and/or compulsive symptoms in order to be diagnosed with OCD.Methods: In this study, experienced clinicians working on a university-based OCD clinic were requested to provide clinical vignettes of patients who, despite having a formal diagnosis of OCD, were felt to display non-genuine forms of this condition.Results: Ten non-consecutive patients with a self-proclaimed diagnosis of OCD were identified and described. Although patients were diagnosed with OCD according to various structured interviews, they exhibited diverse combinations of the following features: (i) overly technical and/or doctrinaire description of their symptoms, (ii) mounting irritability, as the interviewer attempts to unveil the underlying nature of these descriptions; (iii) marked shifts in symptom patterns and disease course; (iv) an affirmative yes pattern of response to interview questions; (v) multiple Axis I psychiatric disorders; (vi) cluster B features; (vii) an erratic pattern of treatment response; and (viii) excessive or contradictory drug-related side effects.Conclusions: In sum, reliance on overly structured assessments conducted by insufficiently trained or naive personnel may result in invalid OCD diagnoses, particularly those that leave no room for clinical judgment.

Exogenous bacterial osteomyelitis in 52 dogs: a retrospective study of etiology and in vitro antimicrobial susceptibility profile (2000-2013)

Background: Most clinical cases of osteomyelitis in dogs involve infectious agents, especially bacteria and fungi. The characterization of these microorganisms may aid in the prevention and treatment of disease.Objective: The aim of this study was to evaluate retrospectively microbiological cultures and in vitro antimicrobial susceptibility profile of isolates from 52 cases of bacterial osteomyelitis in long bones of dogs over 2000-2013. In 78% of the cases injuries were caused by a motor vehicle accident, but there were a few cases of dog bites (17%) and ascending infection due to pododermatitis (5%).Animals and methods: The isolated microorganisms were identified based on conventional phenotypic methods. In vitro disk diffusion test was performed using 30 different antimicrobials.Results: The isolates were obtained from femur (28%), humerus (16%), tibia (31%), and radius/ulna (25%). Among 52 cases, culture was positive in 88% of cases. Thirteen genus of different species of microorganisms were isolated. The most common microorganisms isolated were Staphylococcus spp. and Escherichia coli followed by Streptococcus spp., enteric bacteria, Corynebacterium sp. and anaerobic bacteria. In 42% of cases cultures were mixed. The most effective drugs against isolated bacteria were amoxicillin and clavulanate potassium (79%) followed by ceftriaxone (69%). High-resistance rates were documented against azithromycin (80%), penicillin (59%), and clindamycin (59%).Conclusions: The present study highlights diverse etiologic agents in cases of infectious bacterial osteomyelitis, with predominance of Staphylococcus genus, and reinforces the importance of obtaining cultures and susceptibility profiles given the high rates of antimicrobial resistance.

Retrospective study of 32 encephalic tumors diagnosed by advanced - image magnetic resonance imaging and computed tomography

The incidence of encephalic tumors in dogs and cats has increased in recent years due to the constant advancement of methods of specialist Diagnostic Imaging: Magnetic Resonance Imaging (MRI) and Computed Tomography (CT), used in small animals. These tools, which were distant in the past, are now becoming increasingly important as an additional aid to the identification of tumor processes in the Central Nervous System. The objective, of the present study, was describe imaging findings obtained in 32 cases of encephalic tumors, through techniques of CT and MR imaging procedures during the years 2004 to 2011. Were diagnosed 19/32 by MRI and 13/32 by CT, being the most affected breed Boxer (9/32), the mean age was 10 years.

Manifestation of molar-incisor hypomineralisation in twins: clinical case reports

Molar-incisor hypomineralisation is a qualitative defect of dental tissue of systemic origin affecting one or more permanent first molars and sometimes the permanent incisors as well. There are still no conclusive data on the aetiology of this hypomineralisation, however, systemic factors such as respiratory diseases and prenatal and perinatal complications are regarded as possible causes. The objective is to present three clinical cases of twins, one Monozygotic and two Dizygotic Twins with molar-incisor hypomineralisation, showing evidence of its manifestation as well as clinical the characteristics and aetiological factors involved. The clinical findings involving twins suggest that ameloblasts are specifically affected in their developmental phase, which includes a number of factors. Although prenatal and perinatal complications are not decisive in the development of molar-incisor hypomineralization, it is suggested a possible genetic susceptibility to the disease. Prospective observational studies using a population sample containing data on the last three months of gestation to the eruption of permanent teeth are needed to confirm the causeeffect relationships.

A six-year retrospective study of maxillofacial fractures from radiographic findings in Brazil

Objective: this study aimed to present the causes and prevalence of maxillofacial fractures that occurred in the region of Araraquara-SP – Brazil, during a 6-year period. Methods: information regarding age, gender, etiology, and maxillofacial fracture site, as well as type of radiographic examination were evaluated. Data were gathered from the radiographic examination and radiographic report of the Division of Dentomaxillofacial Radiology, and from charts of the Division of Oral and Maxillofacial Surgery of patients attending for maxillofacial fractures from 2004 to 2009. A descriptive statistical analysis was developed using Epi-Info 3.5.1. Results: from a total of 11,728 patients assisted, 407 patients presented maxillofacial fractures. The prevalent age ranged from 21 to 30 years old. From the total patients, 322 were men and 85 were women (ratio of men to women was 3.8:1). Panoramic radiography (n = 306) was most frequently used to observe maxillofacial fractures. Mandibular fractures were frequent in the body of the mandible (n = 127), followed by symphysis (n = 102), and the prevalent cause was traffic accidents (n = 161). Conclusion: more than half of affected individuals were younger than 40 years of age. The body of the mandible was the most common fracture location visualized by panoramic radiography for traffic accidents and fights.

Orbital wall reconstruction with titanium mesh:Retrospective study of 24 patients

The aim of this study was to evaluate the efficacy and safety of traumatic orbital defect reconstruction with titanium mesh. A retrospective study was made. Evaluations were made after a minimum postoperative follow-up of 12 months, looking for the main complications. Twenty-four patients were included in this evaluation; 19 were male (79.1%) and 5 (20.8%) were female. The main injury etiology was vehicle accidents (50%) followed by other causes. Fourteen patients (58.3%) presented orbital floor fractures, and 10 had more than one wall fractured (41.6%). Permanent infraorbital nerve hypoesthesia was observed in two patients (8.3%), enophthalmos occurred in five patients (20.8%), and exophthalmos was found in two patients (8.3%). Four patients (16.6%) still presented evidence of residual prolapsed intraorbital content, and one of those needed further surgical correction; sinusitis occurred in one patient (4.1%). Titanium mesh is a reliable option for orbital reconstruction, despite some complications found in this sample.

Survival rate of osseointegrated implants in atrophic maxillae grafted with calvarial bone: a retrospective study

The aim of this study was to evaluate the clinical survival rate of osseointegrated implants placed in the atrophic maxilla that has been reconstructed by means of autogenous bone grafts harvested from a cranial calvarial site. Further, we sought to analyse the level of pen-implant bone after prosthetic rehabilitation and to determine subjective patient satisfaction with the treatment performed. This study conformed to the STROBE guidelines regarding retrospective studies. Twenty-five patients who had received osseointegrated implants with late loading in the reconstructed atrophic maxilla were included in the study. The survival rate and level of pen-implant bone loss were evaluated. A questionnaire related to the surgical and prosthetic procedures was completed. The observed implant survival rate was 92.35%. The mean bone loss recorded was 1.76 mm in the maxilla and 1.54 mm in the mandible. The results of the questionnaire indicated a high level of patient satisfaction, little surgical discomfort, and that the patients would recommend the procedure and would undergo the treatment again. From the results obtained, it is concluded that the cranial calvarial site is an excellent donor area; calvarial grafts provided stability and maintenance of bone volume over the course of up to 11 years.

Direct retrospective comparison of adalimumab and infliximab in preventing early postoperative endoscopic recurrence after ileocaecal resection for crohn's disease: results from the MULTIPER database

Both adalimumab [ADA] and infliximab [IFX] seem to be effective in the prevention of early postoperative endoscopic recurrence [EPER] after ileocaecal resection in Crohn's disease [CD] patients. There is lack of data with direct comparison between the two agents in the postoperative scenario. The aim of this study was to compare the rates of EPER in patients treated with ADA and IFX after ileocaecal resection for CD. This was a multicentre retrospective analysis of EPER rates in CD patients after ileocaecal resections, from seven referral centres in three countries. Endoscopic recurrence was defined as Rutgeerts' score ≥ i2. The patients were allocated according to treatment to two groups: ADA or IFX. The EPER rates were compared between the two treatment groups. Among the 168 patients included in the database, 96 received anti-tumour necrosis factor [TNF] agents after resection [37 in the ADA and 59 in the IFX groups] and were included in this comparative study. The groups were comparable in all baseline characteristics, mainly age, gender, previous resections, perianal CD, and mono or combination therapy. EPER was identified in 9/37 [24.32%] in the ADA group vs 16/59 [27.12%] in the IFX group [p = 0.815]. In this retrospective direct comparison between ADA and IFX therapy after ileocaecal resection, there was no significant difference between the two anti-TNF agents in terms of EPER rates. However, prospective randomised studies are needed to confirm these data and better define the role of each agent in the prevention of EPER.

Relation between bruxism and dental implants

OBJECTIVE: The aim of this study was to gather information and discuss the predictability of implant-supported prostheses in patients with bruxism by performing a literature review. METHODS: In order to select the studies included in this review, a detailed search was performed in PubMed and Medline databases, using the following key words: bruxism, dental implants, implant supported prosthesis, and dental restoration failure. Items that were included are: case reports, randomized controlled trials, in vitro studies, literature and systematic reviews, with or without meta-analysis, of the last 20 years that addressed the theme. Articles without abstracts, animal studies, articles in languages other than English and articles from journals unrelated to the dental field were excluded. RESULTS: after analysis according to inclusion and exclusion criteria, 28 articles were selected from a total of 54. It is known from the array of scientific articles which have assessed, either through retrospective, prospective or experimental studies, that the biomechanical and biological impact of bruxism on implant-supported prostheses is small, and that the literature has contributed little to exemplify the prosthetic limits of safety for the specialist from a clinical point of view. CONCLUSION: Although there is still no general consensus on this matter, most of the literature review articles do provide clinical guidelines that contribute to implant supported prostheses longevity and stability in patients with bruxism.

Auditoria em Saúde: justificativas de glosas no setor odontológico

Objective – To collecting data about the main explanations for glosses and demonstrating the percentage of production loss in the odontologic procedures. Methods – It is about an epidemiological study of historical series, retrospective and quantitative, based on the data collection of DATASUS information system and reports realized by the city of Aquidauana/MS audit system from 2001 to 2010. Results – The results show that in this period, 921.300 odontologic procedures were presented as production; being 223.226 (24,2%) individual procedures and 698.074 (75,8%) collective. There were 23.881 (2,6%) glosses, being 10.158 (42,5%) in the collective procedures and 13.723 (57,5%) in the individual ones. The main cause for glosses related to individual procedures was the repetition of procedures for the same patient and the same tooth (42,4%). In the collective activities, it was the non-accomplishment of the oral health collective program (68,9%). There was an increase of loss in the individual procedures going from less than 5% in the period of 2001 to 2007; to 5,8 % in 2008; 8,9% in 2009 and 14,1 % in 2010 and in the collective procedures the loss reached 4% in 2010. Conclusion – It was concluded that the most frequent cause of glosses explanation was the repetition of procedures for the same patient and the same tooth in the individual cases and the non-accomplishment of the oral health collective program in the collective activities. The importance of the audit system as a trust-worthy instrument for the managers in the planning and evaluation of health actions with the intention of guarantee the solution of the serv-ices provided.

Clinical evaluation of the bicoronal flap in the treatament of facial fractures: retrospective study of 132 patients

The aim of the present study was to evaluate the postoperative complications of bicoronal flaps used to treat facial fractures. One hundred and thirty two patients that received bicoronal flaps for the treatment of upper and middle third facial fractures were called for clinical and radiographic examination. Minimum follow-up was 1 year and all patients had charts with adequate information about their perioperative care pertinent to the study. Results showed as complications hypoesthesia (17%), partial unilateral frontal motor deficit (11%), infection (3%), hypertrophic scars (3%), varying degrees of alopecia (18%), seroma or hematoma in the immediate postoperative period (5%). The flap provided wide surgical access to the upper and middle facial thirds with very few serious complications, most frequently allowing good aesthetic results.

Phytogeographic retrospective in ecotonal areas guided by soil attributes

Re-establishing deforested ecosystems to pre-settlement vegetation is difficult, especially in ecotonal areas, due to lack of knowledge about the original physiognomy. Our objective was to use a soils database that included chemical and physical parameters to distinguish soil samples of forest from those of savannah sites in a municipality located in the southeastern Brazil region. Discriminant analysis (DA) was used to determine the original biome vegetation (forest or savannah) in ecotone regions that have been converted to pasture and are degraded. First, soils of pristine forest and savannah sites were tested, resulting in a reference database to compare to the degraded soils. Although the data presented, in general had a high level of similarity among the two biomes, some differences occurred that were sufficient for DA to distinguish the sites and classify the soil samples taken from grassy areas into forest or savannah. The soils from pastured areas presented quality worse than the soils of the pristine areas. Through DA analysis we observed that, from seven soil samples collected from grassy areas, five were most likely originally forest biome and two were savannah, ratified by a complementary cluster analysis carried out with the database of these samples. The model here proposed is pioneer. However, the users should keep in mind that using this technology, i.e., establishing a regional-level database of soil features, using soil samples collected both from pristine and degraded areas is critical for success of the project, especially because of the ecological and regional particularities of each biome.
