Longitudinal clinical and radiographic evaluation of severely intruded permanent incisors in a pediatric population

Intrusion is defined as the axial dislodgment of the tooth into its socket and is considered one of the most severe types of dental trauma. This longitudinal outcome study was undertaken to evaluate clinically and radiographically severely intruded permanent incisors in a population of children and adolescents. All cases were treated between September 2003 and February 2008 in a dental trauma service. Clinical and radiographic data were collected from 12 patients (eight males and four females) that represented 15 permanent maxillary incisors. Mean age at the time of injury was 8 years and 9 months (range 7-14 years and 8 months). Mean time elapsed to follow-up was 26.6 months (range 10-51 months). The analysis of data showed that tooth intrusion was twice as frequent in males. The maxillary central incisors were the most commonly intruded teeth (93.3%), and falling at home was the main etiologic factor (60%). More than half of the cases (53.3%) were multiple intrusions, 73.3% of the intruded teeth had incomplete root formation and 66.6% of the teeth suffered other injuries concomitant to intrusion. Immediate surgical repositioning was the treatment of choice in 66.7% of the cases, while watchful waiting for the tooth to return to its pre-injury position was adopted in 33.3% of the cases. The teeth that suffered additional injuries to the intrusive luxation presented a fivefold increased relative risk of developing pulp necrosis. The immature teeth had six times more chances of presenting pulp canal obliteration that the mature teeth and a lower risk of developing root resorption. The most frequent post-injury complications were pulp necrosis (73.3%), marginal bone loss (60%), inflammatory root resorption (40%), pulp canal obliteration (26.7%) and replacement root resorption (20%). From the results of this study, it was not possible to determine whether the type immediate treatment had any influence on the appearance of sequelae like pulp necrosis and root resorption after intrusive luxation, but the existence of additional injuries and the stage of root development influenced the clinical case outcome in a negative and positive manner, respectively.

Comparação do equilíbrio e qualidade de vida entre idosos institucionalizados e não-institucionalizados

Introduction: the improvements on the health area increased the brazilians life expectative. Because of it, more people becomes elder, passing through various common processes of aging, as the balance decrease. Resulting form this the risk of fall increase, and this has a negative impact on the quality of life. As more people become elder the institutionalization tax increase. Objectives: compare the balance and quality of life between institutionalized and non-institutionalized elders; correlate the Berg Balance Scale (BBS) with the Timed Up and Go test (TUG) and with the questionnaire “The Medical Outcome Study 36 – Item Short-Form Health Survey” (SF-36). Methods: were evaluated 20 elders, ten institutionalized (GI) and ten non-institutionalized (GNI). To the balance assessment were used the BBS and the TUG, the quality of life was evaluated using the SF-36. The signifi cance level was set to 5% (p<0,05). The GraphPad Prism 5# was used to analyze the data. To identify the distribution of the data was applied the Shapiro-Wilk test. In the comparison between groups, the normal distributed data were analyzed with the Unpaired Student t test. The non-normal distributed data were analyzed with the Mann-Whitney non-parametric test. The correlations were analyzed with the Pearson (normal data) and Spearman’s (non-normal data) tests. Results: the age average for each group was 72,8±8,36 years (GI) e 67,4±3,53 years (GNI). The GNI had a better performance than the GI in the BBS (*p=0,0017) as in the TUG (*p<0,0002). There wasn’t difference between the quality of life. There was correlation between EEB and TUG (-0,8907 for the GI and -0,7180 for the GNI) and between EEB and the functional capacity domain from the SF-36 (0,7657). Conclusion: the non-institutionalized elders presented best balance. It was found good correlation between TUG and BBS. In the studied sample, to be institutionalized didn’t infl uenced the quality of life.

Escala de coma de Glasgow e qualidade de vida pós-trauma cranioencefálico

OBJETIVO: Avaliar o desempenho de diferentes escores da Escala de Coma de Glasgow (ECGl) observados nas primeiras 72 horas pós trauma perante a qualidade de vida e mudança percebida do estado de saúde, após um ano do evento traumático. MÉTODOS: Estudo de abordagem quantitativa, observacional, longitudinal, descritivo e correlacional com vítimas de trauma cranioencefálico contuso (TCEC) avaliadas, diariamente durante a internação hospitalar, e após um ano por meio do Medical Outcome Study 36-item Short Form Health Survey (SF-36). RESULTADOS: sob as curvas Reciever Operator Characteristics dos valores da ECGl referentes à mudança percebida do estado de saúde não apresentaram diferença significativa e variaram de 0,63 a 0,71. Correlação, estatisticamente significante, porém fraca, foi observada entre os escores da ECGl e alguns dos domínios do SF-36. CONCLUSÃO: Verificou-se que os diferentes valores da ECGl apresentaram limitações para que fossem aplicados na prática clínica para estimar as consequências do TCEC a longo prazo.

More accurate component alignment in navigated total knee arthroplasty has no clinical benefit at 5-year follow-up

Computer navigation in total knee arthroplasty is somewhat controversial. We have previously shown that femoral component positioning is more accurate with computed navigation than with conventional implantation techniques, but the clinical impact of this is unknown. We now report the 5-year outcome of our previously reported 2-year outcome study.

Differences between first episode schizophrenia and schizoaffective disorder

Background The diagnostic and clinical overlap between schizophrenia and schizoaffective disorder is an important nosological issue in psychiatry that is yet to be resolved. The aim of this study was to compare the clinical and functional characteristics of an epidemiological treated cohort of first episode patients with an 18-month discharge diagnosis of schizophrenia (FES) or schizoaffective disorder (FESA). Methods This study was part of the larger First Episode Psychosis Outcome Study (FEPOS) which involved a medical file audit study of all 786 patients treated at the Early Psychosis Prevention and Intervention Centre between 1998 and 2000. Of this cohort, 283 patients had an 18-month discharge diagnosis of FES and 64 had a diagnosis of FESA. DSM-IV diagnoses and clinical and functional ratings were derived and validated by two consultant psychiatrists. Results Compared to FES patients, those with FESA were significantly more likely to have a later age of onset (p=.004), longer prodrome (p=.020), and a longer duration of untreated psychosis (p<.001). At service entry, FESA patients presented with a higher illness severity (p=.020), largely due to the presence of more severe manic symptoms (p<.001). FESA patients also had a greater number of subsequent inpatient admissions (p=.017), had more severe depressive symptoms (p=.011), and higher levels of functioning at discharge. Discussion The findings support the notion that these might be considered two discernable disorders; however, further research is required to ascertain the ways and extent to which these disorders are discriminable at presentation and over time.

Small is beautiful: why profundaplasty should not be forgotten

BACKGROUND: Surgical profundaplasty (SP)is used mainly as an adjunct to endovascular management of peripheral vascular disease (PAD) today. Results from earlier series of profundaplasty alone have been controversial, especially regarding its hemodynamic effect. The question is: Can profundaplasty alone still be useful? Our aim was to evaluate its role in the modern management of vascular patients. METHODS: This was a retrospective outcome study. A consecutive series of 97 patients (106 legs) from January 2000 through December 2003 were included. In 55 (52%) legs, the superficial femoral artery was occluded. These patients were included in the current analysis. Of these patients 14 (25%) were female. Mean age was 71 ((11) years. Nineteen (35%) were diabetic. The indication for operation was claudication in 29 (53%), critical leg ischemia (CLI) in 26 (47%), either with rest pain in 17 (31%), or ulcer/gangrene in 9 (16%). Endarterectomy with patch angioplasty with bovine pericardium was performed in all cases. Mean follow-up was 33 ( 14 months. Mean preoperative ankle brachial index (ABI) was 0.6. Sustained clinical efficacy was defined as upward shift of 1 or greater on the Rutherford scale without repeat target limb revascularization (TLR) or amputation. Mortality, morbidity, need for TLR, or amputation were separate endpoints. RESULTS: Postoperatively, ABI was significantly improved (mean = 0.7), in 24 (44%) by more than 0.15. At three years, cumulative clinical success rate was 80%. Overall, patients with claudication had a better outcome than those with CLI (p = 0.04). Two (4%) major amputations and 2 (4%) minor ones were performed, all in patients with CLI. None of the 9 (16%) ulcers healed. CONCLUSION: Profundaplasty is still a valuable option for patients with femoral PAD and claudication without tissue loss. It is a straightforward procedure that combines good efficacy with low complication rates. Further endovascular treatment may be facilitated. It is not useful for patients with the combination of critical ischemia and tissue loss.

Laser-Doppler measurements of spinal cord blood flow changes during hemilaminectomy in chondrodystrophic dogs with disk extrusion

OBJECTIVES: (1) To assess spinal cord blood flow (SCBF) during surgical treatment of disk extrusion in dogs and (2) to investigate associations between SCBF, clinical signs, presurgical MRI images, and 24-hour surgical outcome. STUDY DESIGN: Cohort study. ANIMALS: Chondrodystrophic dogs with thoracolumbar disk extrusion (n=12). METHODS: Diagnosis was based on clinical signs and MRI findings, and confirmed at surgery. Regional SCBF was measured intraoperatively by laser-Doppler flowmetry before, immediately after surgical spinal cord decompression, and after 15 minutes of lavaging the lesion. Care was taken to ensure a standardized surgical procedure to minimize factors that could influence measurement readings. RESULTS: A significant increase in intraoperative SCBF was found in all dogs (Wilcoxon's signed-rank test; P=.05) immediately after spinal cord decompression and after 15 minutes. Changes in SCBF were not associated with duration of clinical signs; initial or 24-hour neurologic status; or degree of spinal cord compression assessed by MRI. CONCLUSION: SCBF increases immediately after spinal cord decompression in dogs with disk herniation; however, increased SCBF was not associated with a diminished 24-hour neurologic status. CLINICAL RELEVANCE: An increase in SCBF does not appear to be either associated with the degree of spinal cord compression or of a magnitude sufficient to outweigh the benefit of surgical decompression by resulting in clinically relevant changes in 24-hour outcome.

Partnering with Parents: Promising Approaches to Improve Reunification Outcomes for Children in Foster Care

Family reunification is one of the central tenents of the child welfare system, yet research supporting effective practices to promote safe reunifications is limited. As a departure from previous initiatives, the Parent Partner (PP) program enlists as staff mothers and fathers who have experienced child removal, services, and reunification. This study examines outcomes for children served by the PP program. The experimental group includes 236 children whose parents were served by a Parent Partner and a matched comparison group of 55 children whose parents were served by the public child welfare agency in 2004, before the Parent Partner program was established. Cases were examined 12 months following case opening to determine reunification status. Results from the outcome study indicate that reunification may be more likely for children whose parents were served by Parent Partners. Although there are limitations to the data, findings from this study suggest that the Parent Partner model may hold promise as a child welfare intervention designed to support reunification.

Dominance of chemokine ligand 2 and matrix metalloproteinase-2 and -9 and suppression of pro-inflammatory cytokines in the epidural compartment after intervertebral disc extrusion in a canine model

BACKGROUND CONTEXT In canine intervertebral disc (IVD) disease, a useful animal model, only little is known about the inflammatory response in the epidural space. PURPOSE To determine messenger RNA (mRNA) expressions of selected cytokines, chemokines, and matrix metalloproteinases (MMPs) qualitatively and semiquantitatively over the course of the disease and to correlate results to neurologic status and outcome. STUDY DESIGN/SETTING Prospective study using extruded IVD material of dogs with thoracolumbar IVD extrusion. PATIENT SAMPLE Seventy affected and 13 control (24 samples) dogs. OUTCOME MEASURES Duration of neurologic signs, pretreatment, neurologic grade, severity of pain, and outcome were recorded. After diagnostic imaging, decompressive surgery was performed. METHODS Messenger RNA expressions of interleukin (IL)-1β, IL-2, IL-4, IL-6, IL-8, IL-10, tumor necrosis factor (TNF), interferon (IFN)γ, MMP-2, MMP-9, chemokine ligand (CCL)2, CCL3, and three housekeeping genes was determined in the collected epidural material by Panomics 2.0 QuantiGene Plex technology. Relative mRNA expression and fold changes were calculated. Relative mRNA expression was correlated statistically to clinical parameters. RESULTS Fold changes of TNF, IL-1β, IL-2, IL-4, IL-6, IL-10, IFNγ, and CCL3 were clearly downregulated in all stages of the disease. MMP-9 was downregulated in the acute stage and upregulated in the subacute and chronic phase. Interleukin-8 was upregulated in acute cases. MMP-2 showed mild and CCL2 strong upregulation over the whole course of the disease. In dogs with severe pain, CCL3 and IFNγ were significantly higher compared with dogs without pain (p=.017/.020). Dogs pretreated with nonsteroidal anti-inflammatory drugs revealed significantly lower mRNA expression of IL-8 (p=.017). CONCLUSIONS The high CCL2 levels and upregulated MMPs combined with downregulated T-cell cytokines and suppressed pro-inflammatory genes in extruded canine disc material indicate that the epidural reaction is dominated by infiltrating monocytes differentiating into macrophages with tissue remodeling functions. These results will help to understand the pathogenic processes representing the basis for novel therapeutic approaches. The canine IVD disease model will be rewarding in this process.

Laboratory recommendations for scoring deep molecular responses following treatment for chronic myeloid leukemia.

Treatment of chronic myeloid leukemia (CML) with tyrosine kinase inhibitors has advanced to a stage where many patients achieve very low or undetectable levels of disease. Remarkably, some of these patients remain in sustained remission when treatment is withdrawn, suggesting that they may be at least operationally cured of their disease. Accurate definition of deep molecular responses (MRs) is therefore increasingly important for optimal patient management and comparison of independent data sets. We previously published proposals for broad standardized definitions of MR at different levels of sensitivity. Here we present detailed laboratory recommendations, developed as part of the European Treatment and Outcome Study for CML (EUTOS), to enable testing laboratories to score MR in a reproducible manner for CML patients expressing the most common BCR-ABL1 variants.Leukemia advance online publication, 27 February 2015; doi:10.1038/leu.2015.29.

Evaluation of the success of medical management for presumptive thoracolumbar intervertebral disk herniation in dogs.

OBJECTIVE To determine the success of medical management of presumptive thoracolumbar disk herniation in dogs and the variables associated with treatment outcome. STUDY DESIGN Retrospective case series. ANIMALS Dogs (n=223) with presumptive thoracolumbar disk herniation. METHODS Medical records from 2 clinics were used to identify affected dogs, and owners were mailed a questionnaire about success of therapy, recurrence of clinical signs, and quality of life (QOL) as interpreted by the owner. Signalment, duration and degree of neurologic dysfunction, and medication administration were determined from medical records. RESULTS Eighty-three percent of dogs (185/223) were ambulatory at initial evaluation. Successful treatment was reported for 54.7% of dogs, with 30.9% having recurrence of clinical signs and 14.4% classified as therapeutic failures. From bivariable logistic regression, glucocorticoid administration was negatively associated with success (P=.008; odds ratio [OR]=.48) and QOL scores (P=.004; OR=.48). The duration of cage rest was not significantly associated with success or QOL. Nonambulatory dogs were more likely to have lower QOL scores (P=.01; OR=2.34). CONCLUSIONS Medical management can lead to an acceptable outcome in many dogs with presumptive thoracolumbar disk herniation. Cage rest duration does not seem to affect outcome and glucocorticoids may negatively impact success and QOL. The conclusions in this report should be interpreted cautiously because of the retrospective data collection and the use of client self-administered questionnaire follow-up. CLINICAL RELEVANCE These results provide an insight into the success of medical management for presumptive thoracolumbar disk herniation in dogs and may allow for refinement of treatment protocols.

Long-term gastrointestinal complications of Clostridium difficile associated diarrhea (CDAD)

Background. The incidence of Clostridium difficile -associated diarrhea (CDAD) is increasing worldwide likely because of increased use of broad spectrum antibiotics and the introduction of a clonal hyper-virulent strain called the BI strain. Short-term complications of CDAD include recurrent disease, requirement for colectomy, and persistent disease. However, data on the long-term consequences of CDAD are scarce. Among other infectious diseases (Shigella, Salmonella, and Campylobacter), long-term consequences such as irritable bowel syndrome (IBS), chronic dyspepsia/diarrhea, and other GI effects have been noted. Since the mechanism of action of these agents is similar to C.difficile, we hypothesized that patients with CDAD have greater likelihood of developing IBS and other functional gastrointestinal disorders (FGIDs) in the long-term as compared to a general sample of recently hospitalized patients. ^ Objective. To evaluate the long-term gastrointestinal complications of CDAD, (IBS, functional diarrhea, functional abdominal bloating, functional constipation and functional abdominal pain syndrome). ^ Methods. The current study was a secondary analysis of a previously completed observational case-control outcome study. Adult CDAD patients at St. Luke's Episcopal Hospital, Houston (SLEH) were followed up and interviewed by telephone six months after the initial diagnosis thereafter evaluated for the development of IBS and other FGIDs. A total of 46 patients with CDAD infection were recruited at SLEH between May-November 2007. The comparators were patients hospitalized in SLEH within one month before or after the admission of the reference case, hospital length of stay within one week longer or shorter than reference case, and age within 10 years more or less than the reference case. Cases and comparators were compared using Fisher's exact test. A p<0.05 was considered significant. ^ Results. Thirty CDAD patients responded to the questionnaires and were compared to 40 comparators. No comparator developed a FGID, while 3 (10%) CDAD patients developed new onset IBS (p=0.07), 4 (13.3%) developed new onset Functional Diarrhea (p=0.03), and 3 (10%) developed new onset Functional Constipation (p=0.07). No patient developed Functional Abdominal Bloating and Functional Abdominal Pain Syndrome. ^ Conclusion. In this study, new onset functional diarrhea was significantly more common in patients CDAD within six months after initial infection compared to matched controls.^

Policy implications of public health workforce development for disaster preparedness in the United States

Public health efforts were initiated in the United States with legislative actions for enhancing food safety and ensuring pure drinking water. Some additional policy initiatives during the early 20th century helped organize and coordinate relief efforts for victims of natural disasters. By 1950's the federal government expanded its role for providing better health and safety to the communities, and its disaster relief activities became more structured. A rise in terrorism related incidents during the late 1990's prompted new proactive policy directions. The traditional policy and program efforts for rescue, recovery, and relief measures changed focus to include disaster preparedness and countermeasures against terrorism.^ The study took a holistic approach by analyzing all major disaster related policies and programs, in regard to their structure, process, and outcome. Study determined that United States has a strong disaster preparedness agenda and appropriate programs are in place with adequate policy support, and the country is prepared to meet all possible security challenges that may arise in the future. The man-made disaster of September 11th gave a major thrust to improve security and enhance preparedness of the country. These new efforts required large additional funding from the federal government. Most existing preparedness programs at the local and national levels are run with federal funds which is insufficient in some cases. This discrepancy arises from the fact that federal funding for disaster preparedness programs at present are not allocated by the level of risks to individual states or according to the risks that can be assigned to critical infrastructures across the country. However, the increased role of the federal government in public health affairs of the states is unusual, and opposed to the spirit of our constitution where sovereignty is equally divided between the federal government and the states. There is also shortage of manpower in public health to engage in disaster preparedness activities, despite some remarkable progress following the September 11th disaster.^ Study found that there was a significant improvement in knowledge and limited number of studies showed improvement of skills, increase in confidence and improvement in message-mapping. Among healthcare and allied healthcare professionals, short-term training on disaster preparedness increased knowledge and improved personal protective equipment use with some limited improvement in confidence and skills. However, due to the heterogeneity of these studies, the results and interpretation of this systematic review may be interpreted with caution.^
