Predicting and reducing cranioplasty infections by clinical, radiographic and operative parameters - A historical cohort study.

Cranioplasty is a relatively straightforward and common procedure, yet it carries a substantial rate of infection that causes major morbidity and mortality. The authors' objective was to assess the effect of various variables on the risk of developing post-cranioplasty infections, and to enable the prediction and reduction of its incidence, contributing to an improved patient-selection. The medical records, microbiologic cultures, imaging studies and operative reports of patients who have undergone cranioplasty between the years 2008-2014 at Sheba Medical Center, a tertiary care teaching hospital in Tel-Hashomer, Israel, were reviewed and evaluated for potential predictive factors of infection. Cox regression was applied for uni- as well as multi-variate analyses, and a Kaplan-Meier curve and Log-Rank test were used to describe the association between neurological deficit prior to operation and occurrence of infection. Eighty-eight patients who had undergone cranioplasties using autologous as well as various artificial materials were included in the study. The overall rate of infection was 13.6%; median time to infection was 30.5 days (interquartile range: 17.35-43.5). Pre-operative degree of neurological disability was the strongest predictor for infection in both uni- and multi-variate analyses (Hazard ratio [HR]=18.9, 95% confidence interval [CI]: 1.9-187 p=0.014). Patients admitted due to trauma (HR=7.04 CI: 0.9-54.6, p=0.062) and autologous graft material (HR=2.88, 95% CI: 0.92-9.09, p=0.07) were associated with a trend toward a higher risk for infection. In conclusion, careful patient selection is a key concept in avoiding harmful post-cranioplasty infections. Modified Rankin Score yields a well-established tool that predicts the risk of infection.

The scope and variety of combined baccalaureate-MD programs in the United States.

The landscape of combined baccalaureate-MD programs has changed substantially in the last two decades but has not been documented in detail. The authors review the current state of these programs and discuss opportunities for future study of their evolving role and potential impact.In 2011, using a definition of baccalaureate-MD program built on prior research, the authors reviewed Association of American Medical Colleges sources and medical school Web sites to identify and characterize 81 active programs. In addition, they surveyed the 57 medical schools offering those programs; 31 schools with 39 programs responded. The resulting database inventories the number and distribution of programs; institutional affiliations; missions or goals; length; size; admissions criteria; curricula; and retention requirements.Since the inception of combined programs in 1961, their number and curricular length have increased. Pressures that spurred earlier programs remain evident in the goals of today's programs: attract talented high school or early college students, especially from diverse backgrounds; prepare physicians to meet societal needs; and offer an enriched premedical environment. Baccalaureate educational activities achieve program goals through special courses, medical experiences, community service, and learning communities tailored to students' needs. Admission and retention criteria are comparable to those of traditional medical schools.Combined baccalaureate-MD programs have evolved along several paths during the last half century and have enriched the baccalaureate experiences of medical students. Shifting expectations for the selection and education of future physicians warrant focused research on these programs to document their effectiveness in addressing those expectations.

Implant-retained feeding aid prosthesis for a patient following total glossectomy and laryngectomy: a clinical report.

This clinical report describes the prosthetic management of a patient following total glossectomy and total laryngectomy that severely compromised his oral function, caused facial disfigurement, and limited the patient's quality of life. A feeding aid prosthesis was designed to address the patient's chief complaint of difficulty in feeding and mastication. The prosthesis was designed as an implant-retained overdenture with a lingual metal plate to facilitate food introduction into the oropharynx. This treatment improved mastication, appearance, and the quality of the patient's social life.

Medical students' experience of academic review and promotions committees.

BACKGROUND: Like all medical schools, Northeastern Ohio Universities College of Medicine (NEOUCOM) has an elaborate committee system for academic review and promotions (ARP). Little research exists locally or nationally on this system. PURPOSE: E-mail invitations to all 420 NEOUCOM currently enrolled students were sent seeking their participation in a qualitative study that involved interviewing students who had appeared before an ARP committee at any time for any reason to understand how they experienced the process. METHOD: NUD*IST software was used to analyze the data generated by the interviews. RESULTS: The invitation drew 19 volunteers from the pool of 84 students who, at the time of the messages, had appeared before an ARP committee at least once. Themes were discovered surrounding students' perceptions of the committee's purpose, their experience of it, their beliefs about students' honesty when appearing before the committee, how they felt about themselves after a committee appearance, and how they would improve the process of academic review.

A preplanned surgical obturator prosthesis for alternative resection lines in the anterior region.

A technique is described that enables adaptation of a surgical obturator to accommodate anterior teeth that may or may not be resected with the lesion at surgery. This is designed and fabricated by placing additional clasps on the teeth in question and providing for a clasp on one of the anterior teeth that can be determined at the time of surgery, thereby allowing anterior retention of the obturator immediately postoperatively. This technique is cost-effective and useful, especially if no prosthodontist is available at the time of surgery to perform obturator modifications.
