Long-term follow-up of successful orthodontic-periodontal treatment of localized aggressive periodontitis: a case report

This report describes a case of localized aggressive periodontitis (localized juvenile periodontitis) that was jointly treated with conventional periodontal therapy, selective extractions to eliminate localized areas of vertical bone loss, and orthodontic therapy. A 20-year follow-up is described in this report. The success of periodontal treatment in a case such as this depends on making an accurate diagnosis, providing periodontal treatment to control the disease, and providing regular periodontal maintenance during and after orthodontic treatment.     

Treatments of unilateral neglect: a review

OBJECTIVES: To review the existing literature on treatments of unilateral neglect, to synthesize findings, and to offer recommendations for future studies. DATA SOURCES: Computerized databases including MEDLINE and PsychINFO. STUDY SELECTION: All studies investigating treatment(s) of unilateral neglect. DATA EXTRACTION: Authors reviewed design and other methodologic issues. DATA SYNTHESIS: Unilateral neglect is a common consequence of right-hemisphere stroke. It is well recognized that the disorder is heterogeneous and has numerous subtypes. There have been numerous studies showing that arousal, hemispheric activation, and spatial attention treatments may all improve neglect, at least transiently. Despite these promising outcomes, little consensus exists as to whether 1 treatment is more efficacious than others, in part because cross-study differences in methodology render meta-analyses difficult, and in part because many studies fail to document duration of treatment effects or generalization to daily activities. One possibility is that these varied and diverse treatments may all be effective, reflecting redundancy in neural circuits devoted to attention and action in space, and consequent flexibility of the spatial processing system. It remains possible, however, that different subtypes of neglect may respond differentially to treatment of various sorts. Most existing studies of neglect have relied on very small populations of neglect patients, whose neglect is characterized only generally. CONCLUSION: Methodologic shortcomings hinder assessment of the efficacy of various types of neglect treatment. In the future, these shortcomings could be addressed with larger studies of well-characterized patients that evaluate duration of treatment effects and include functional measures. In addition, the role of overarching variables, such as reduced arousal, requires consideration. The ultimate goal of these studies might be the development of triaging strategies wherein neglect patients are assigned to treatments of most likely benefit on the basis of neuroanatomic and behavioral profiles.     

Integrating public health students into interprofessional education

ABSTRACT

Recognizing the public health professional are critical members of interprofessional teams, the Council on Education for Public Health (CEPH) recently added a required Masters of Public Health (MPH) student competency focused on interprofessional education (IPE). A student-centered approach to the design and evaluation of an emergency preparedness-focused curricular program to meet the interprofessional needs of MPH students was used to meet this expectation at the University of Washington. Curriculum design was informed by two 80-minute listening sessions with MPH students to better understand their current interprofessional educational experiences and needs, and how an emergency preparedness-focused two-hour Interprofessional Active Learning Series (iPALS) session could help them develop interprofessional competency. The resultant iPALS session was assessed with a short, paper-based questionnaire. We found MPH students have an interest in participating in IPE, and that all students who participated in the emergency preparedness-focused iPALS session reported significant increases in their interprofessional and disaster response abilities based on their pre- and post-session evaluations. Student-centered IPE curriculum focused on emergency preparedness can enhance the self-reported ability of students across the health sciences to perform on interprofessional teams while engaging in a topic that has relevance to MPH students.     

Complete nucleotide sequence of a 92-kilobase plasmid harboring the CTX-M-15 extended-spectrum beta-lactamase involved in an outbreak in long-term-care facilities in Toronto, Canada

A major outbreak involving an Escherichia coli strain that was resistant to expanded-spectrum cephalosporins occurred in Toronto and surrounding regions in 2000 to 2002. We report the complete sequence of a plasmid, pC15-1a, that was found associated with the outbreak strain. Plasmid pC15-1a is a circular molecule of 92,353 bp consisting of two distinct regions. The first is a 64-kb region that is essentially homologous to the non-R-determinant region of plasmid R100 except for several point mutations, a few small insertions and deletions, and the absence of Tn10. The second is a 28.4-kb multidrug resistance region (MDR) that has replaced the R-determinant region of the R100 progenitor and consists mostly of transposons or partial transposons and five copies of the insertion element IS26. All drug resistance genes found in pC15-1a, including the beta-lactamase genes bla(CTX-M-15), bla(OXA-1), and bla(TEM-1), the tetracycline resistance gene tetA, and aminoglycoside resistance genes aac(6')-Ib and aac(3)-II, are located in the MDR. The bla(CTX-M-15) gene was found downstream of ISEcp1as part of a transposition unit, as determined from the surrounding sequence. Examination of the plasmids from CTX-M-15-harboring strains isolated from hospitals across Canada showed that pC15-1a was found in several strains isolated from a site in western Canada. Comparison of pC15-1a and pCTX15, found in an E. coli strain isolated in India in 1999, revealed that the plasmids had several features in common, including an R100 backbone and several of the resistance genes, including bla(CTX-M-15), bla(TEM-1), bla(OXA-1), tetA, and aac(6')-Ib.     

Characterization and Treatment of Local Recurrence Following Breast Conservation for Ductal Carcinoma In Situ

Purpose

The optimal treatment strategy for ductal carcinoma in situ (DCIS) continues to evolve and should consider the consequences of initial treatment on the likelihood, type, and treatment of recurrences.

Methods

We conducted a retrospective cohort study using two data sources of patients who experienced a recurrence (DCIS or invasive cancer) following breast-conserving surgery (BCS) for index DCIS: patients with an index DCIS diagnosed from 1997 to 2008 at the academic institutions of the National Comprehensive Cancer Network (NCCN; N = 88) and patients with an index DCIS diagnosed from 1990 to 2001 at community-based integrated healthcare delivery sites of the Health Maintenance Organization Cancer Research Network (CRN) (N = 182).

Results

Just under half of local recurrences in both cohorts were invasive cancer. While 40 % of patients in both cohorts underwent mastectomy alone at recurrence, treatment of the remaining patients varied. In the earlier CRN cohort, most other patients underwent repeat BCS (39 %) with only 18 % receiving mastectomy with reconstruction, whereas only 16 % had repeat BCS and 44 % had mastectomy with reconstruction in the NCCN cohort. Compared with patients not treated with radiation, those who received radiation for index DCIS were less likely to undergo repeat BCS (NCCN: 6.6 vs. 37 %, p = 0.001; CRN: 20 vs. 48 %, p = 0.0004) and more likely to experience surgical complications after treatment of recurrence (NCCN: 15 vs. 4 %, p = 0.17; CRN: 40 vs. 25 %, p = 0.09).

Conclusion

We found that treatment of recurrences after BCS and subsequent complications may be affected by the use of radiotherapy for the index DCIS. Initial treatment of DCIS may have long-term implications that should be considered.     

Orthosis versus no orthosis for the treatment of thoracolumbar burst fractures without neurologic injury: a multicenter prospective randomized equivalence trial

Background contextThoracolumbar burst fractures have good outcomes when treated with early ambulation and orthosis (TLSO). If equally good outcomes could be achieved with early ambulation and no brace, resource utilization would be decreased, especially in developing countries where prolonged bed rest is the default option because bracing is not available or affordable.PurposeTo determine whether TLSO is equivalent to no orthosis (NO) in the treatment of acute AO Type A3 thoracolumbar burst fractures with respect to their functional outcome at 3 months.Study designA multicentre, randomized, nonblinded equivalence trial involving three Canadian tertiary spine centers. Enrollment began in 2002 and 2-year follow-up was completed in 2011.Patient sampleInclusion criteria included AO-A3 burst fractures between T11 and L3, skeletally mature and older than 60 years, 72 hours from their injury, kyphotic deformity lower than 35°, no neurologic deficit. One hundred ten patients were assessed for eligibility for the study; 14 patients were not recruited because they resided outside the country (3), refused participation (8), or were not consented before independent ambulation (3).Outcome measuresRoland Morris Disability Questionnaire score (RMDQ) assessed at 3 months postinjury. The equivalence margin was set at δ=5 points.MethodsThe NO group was encouraged to ambulate immediately with bending restrictions for 8 weeks. The TLSO group ambulated when the brace was available and weaned from the brace after 8 to 10 weeks. The following competitive grants supported this work: VHHSC Interdisciplinary Research Grant, Zimmer/University of British Columbia Research Fund, and Hip Hip Hooray Research Grant. Aspen Medical provided the TLSOs used in this study. The authors have no financial or personal relationships that could inappropriately influence this work.ResultsForty-seven patients were enrolled into the TLSO group and 49 patients into the NO group. Forty-six participants per group were available for the primary outcome. The RMDQ score at 3 months postinjury was 6.8±5.4 (standard deviation [SD]) for the TLSO group and 7.7±6.0 (SD) in the NO group. The 95% confidence interval (?1.5 to 3.2) was within the predetermined margin of equivalence. Six patients required surgical stabilization, five of them before initial discharge.ConclusionsTreating these fractures using early ambulation without a brace avoids the cost and patient deconditioning associated with a brace and complications and costs associated with long-term bed rest if a TLSO or body cast is not available.     

Primary Gleason Grade 4 at the Positive Margin Is Associated with Metastasis and Death Among Patients with Gleason 7 Prostate Cancer Undergoing Radical Prostatectomy

Background

The presence of a positive surgical margin (PSM) at radical prostatectomy (RP) has been linked to an increased risk of biochemical recurrence and receipt of secondary therapy; however, its association with other oncologic end points remains controversial.

Objective

To evaluate the association of primary Gleason grade (GG) at the site of PSM with subsequent clinical progression and mortality among patients with Gleason score (GS) 7 prostate cancer (PCa).

Design, setting, and participants

We identified 1036 patients who underwent RP between 1996 and 2002. A single uropathologist re-reviewed all specimens noted to have a PSM to record GG at the margin.

Outcome measurements and statistical analysis

Survival was estimated using the Kaplan-Meier method. Cox models were used to analyze the association of margin primary GG with outcome.

Results and limitations

Overall, 338 men (33%) had a PSM; of those, 242 had PSM GG3 and 96 had PSM GG4. Median postoperative follow-up was 13 yr. Compared with men with PSM GG3 or a negative SM, we noted that men with PSM GG4 had significantly worse 15-yr systemic progression-free survival (74% vs 90% vs 93%, respectively; p < 0.001) and cancer-specific survival (86% vs 96% vs 97%, respectively; p = 0.002). On multivariable analysis, the presence of PSM GG4 was associated with increased risks of systemic progression (hazard ratio [HR]: 2.77; p = 0.003) and death from PCa (HR: 3.93; p = 0.02) among men with a PSM. Limitations include the relatively small rate of disease recurrence.

Conclusions

PSM primary GG4 was independently associated with adverse oncologic outcomes among men with GS7 PCa. Pending external validation, GG at the PSM may be considered for inclusion in pathologic reports and risk stratification following RP.

Patient summary

Among patients with Gleason grade 7 prostate cancer and a positive surgical margin at the time of prostatectomy, we found that higher Gleason grade at the margin was associated with worse oncologic outcomes.
