Arthrogryposis multiplex congenita

From 1975 to 2004 a total of 38 children handicapped by congenital multiple arthrogryposis were cared for. The congenital joint contractures demand a major effort in terms of surgical reconstruction. In the case of distal arthrogryposis the chances that patients will be able to walk without help are good, while those with amyoplasia are likely to be dependent on mobility aids throughout their lives. The ultimate goal of treatment for patients is to develop into self-confident adults who can cope with life despite their handicaps. The hip in arthrogryposis shows variable forms of pathology, ranging from the almost normal hip to hip contractures with dislocation. Its treatment has some limited advantages, but hardly improves mobility. The knee contractures are actively treated to allow patients to sit, stand and walk better. The club foot and the rocker-bottom foot need sophisticated conservative and operative treatments. If conservative manipulation of bilateral extension contractures of the elbow fails operative treatment is carried out on the dominant side. For shoulder, hand and finger contractures conservative manipulation brings about little improvement, and surgical approaches help hardly at all.     

Comparison of polymerase chain reaction with standard methods in the diagnosis ofMycobacterium tuberculosis infection

The polymerase chain reaction (PCR) method was evaluated in the detection ofMycobacterium tuberculosis in comparison with direct microscopy and culture procedures including the standard radiometric system (Bactec). Amplified DNA fragments from clinical samples were analyzed by dot-blot and non-radioactive oligonucleotide hybridization techniques or by agarose gel electrophoresis. The results revealed nested PCR to be the method of choice. The combination of three culture methods could detectMycobacterium tuberculosis in only 79 % of PCR-positive cases. The mean time required to achieve a positive culture result was 17 days in contrast to the PCR method requiring only two to three days. The nested PCR assay provided rapid and reliable results allowing a definitive diagnosis particularly in a number of samples which were negative on culture.     

Ein neues Zeichen zum Nachweis der Schußabgabe durch eigene Hand?

Zusammenfassung Es wird über zwei Fälle von tödlichen Kopfschüssen berichtet (Einschußwunden rechte Schläfe, absolute Nahschüsse, Kaliber 7,65 bzw. 9 mm), bei denen im Spalt des rechten Schultergelenks Blutungen festgestellt werden konnten. Diese werden durch Überdehnung bei Schußabgabe und extremer Gelenkposition erklärt. Sie könnten, sollten sie sich in einem größeren Obduktionsgut bestätigen, ein Hinweis für eigene Hand sein.     

Inter-observer and intra-observer reliability in the radiographic measurements of paediatric forefoot alignment

BackgroundFoot bones in children have more rounded shapes in radiograms than adults. Thus, the goal of this work was assessing inter- and intra-observer reliability in paediatric forefoot angle measurements.Material and methodsSix forefoot angles in 34 AP standing paediatric foot radiographs were measured by 5 researchers. A classic statistical analysis with use of IBM SPSS Statistics 25 was performed and a new method with two-way analysis of variance was applied.ResultsResults of statistical analysis revealed the properties of a subjective assessment related to specific angles. Kilmartin’s angle, calcaneus-fifth metatarsal angle and first ray angle are the most reliable; metatarsus adductus angle should be used with great caution in pediatric population. Engel’s angle is the most difficult for measuring and measurement error is the highest.ConclusionThe power of paediatric forefoot measurements is various. Several angles are reliable, while Engle’s angle is the most doubtful.     

The Role of One-Stage Exchange for Prosthetic Joint Infection

Purpose of Review

In an era of increasing numbers of hip and knee replacements, strategies to manage prosthetic joint infection (PJI) that are effective at infection control with good patient-reported outcomes and cost containment for health systems are needed. Interest in single-stage exchange for PJI is rising and we assess evidence from the last 5 years related to this treatment strategy.

Recent Findings

Only five series for total knee replacement and ten series for total hip replacement have been reported in the last five years. More review articles and opinion pieces have been written. Reinfection rates in these recent studies range from 0 to 65%, but a meta-analysis and systematic review of all studies showed a reinfection rate of 7.6% (95% CI 3.4–13.1) and 8.8% (95% CI 7.2–10.6) for single-stage and two-stage revisions respectively. There is emerging evidence to support single-stage revision in the setting of significant bony deficiency and atypical PJIs such as fungal infections.

Summary

Prospective randomised studies are recruiting and are necessary to guide the direction of single-stage revision selection criteria. The onus of surgical excellence in mechanical removal of implants, necrotic tissue, and biofilms lies with the arthroplasty surgeon and must remain the cornerstone of treatment. Single-stage revision may be considered the first-line treatment for all PJIs unless the organism is unknown, the patient is systemically septic, or there is a poor tissue envelope.

     

The AAGP Scholars Program: Predictors of Pursuing Geriatric Psychiatry Fellowship Training

ObjectiveThe American Association for Geriatric Psychiatry (AAGP) Scholars Program was developed to recruit trainees into geriatric psychiatry fellowships and is considered a pipeline for fellowship recruitment. Nonetheless, the number of trainees entering geriatric psychiatry fellowship is declining, making it important to identify modifiable factors that may influence trainees’ decisions to pursue fellowship. We analyzed survey data from Scholars Program participants to identify demographic characteristics, attitudes toward program components, and behaviors after the program that were independently associated with the decision to pursue fellowship.MethodsWeb-based surveys were distributed to all 289 former Scholars participants (2010–2018), whether or not they had completed geriatric psychiatry fellowships. We conducted a hierarchical binary logistic regression analysis to examine demographics, program components, and behaviors after the program associated with deciding to pursue geriatric psychiatry fellowship.ResultsSixty-one percent of Scholars decided to pursue geriatric psychiatry fellowship. Attending more than one AAGP annual meeting (relative variance explained [RVE] = 34.2%), maintaining membership in the AAGP (RVE = 28.2%), and rating the Scholars Program as important for meeting potential collaborators (RVE = 26.6%) explained the vast majority of variance in the decision to pursue geriatric psychiatry fellowship.ConclusionNearly two-thirds of Scholars Program participants decided to pursue geriatric psychiatry fellowship, suggesting the existing program is an effective fellowship recruitment pipeline. Moreover, greater involvement in the AAGP longitudinally may positively influence Scholars to pursue fellowship. Creative approaches that encourage Scholars to develop collaborations, maintain AAGP membership, and regularly attend AAGP annual meetings may help attract more trainees into geriatric psychiatry.
