We reviewed 36 cases of forearm deformity caused by multiple osteochondromas in 30 patients and classified them into three types: Type I showed a combination of ulnar shortening and bowing of the radius secondary to osteochondromas of the distal ulna (22 forearms). Type II showed dislocation of the radial head, either with osteochondromas of the proximal radius (Type IIa, two forearms) or secondary to more distal involvement (Type IIb, five forearms). Type III had relative radial shortening due to osteochrondromas at the distal radius (seven forearms). Operations were performed on 16 forearms in 13 patients, with 92% of satisfactory results. For Type I deformity, excision of osteochondromas, immediate ulnar lengthening and corrective osteotomy of the radius are recommended. For Type IIa, excision of the radial head is necessary, and for Type IIb, we advise gradual lengthening of the ulna using an external fixator. Excision of osteochondromas alone gave good results in Type III deformity. Our classification gives a reliable indication of the prognosis and is a guide to the choice of surgical treatment.

Neurotization of the MCN by surgically connecting ICNs is a safe, reliable, and effective procedure for reconstruction of the brachial plexus in patients suffering from birth-related palsy.

BackgroundMajor curriculum reform of undergraduate medical education occurred during the past decades in the United Kingdom (UK); however, the effects of the hidden curriculum, which influence the choice of primary care as a career, have not been sufficiently recognized. While Japan, where traditionally few institutions systematically foster primary care physicians and very few have truly embraced family medicine as their guiding discipline, has also experienced meaningful curriculum reform, the effect of the hidden curriculum is not well known. The aim of this study is to identify themes pertaining to the students' perceptions of the hidden curriculum affecting undergraduate medical education in bedside learning in Japan.MethodsSemi-structured interviews with thematic content analysis were implemented. Undergraduate year-5 students from a Japanese medical school at a Japanese teaching hospital were recruited. Interview were planned to last between 30 to 60 minutes each, over an 8-month period in 2007. The interviewees' perceptions concerning the quality of teaching in their bedside learning and related experiences were collected and analysed thematically.ResultsTwenty five medical students (18 males and 7 females, mean age 25 years old) consented to participate in the interviews, and seven main themes emerged: "the perception of education as having a low priority," "the prevalence of positive/negative role models," "the persistence of hierarchy and exclusivity," "the existence of gender issues," "an overburdened medical knowledge," "human relationships with colleagues and medical team members," and "first experience from the practical wards and their patients."ConclusionsBoth similarities and differences were found when comparing the results to those of previous studies in the UK. Some effects of the hidden curriculum in medical education likely exist in common between the UK and Japan, despite the differences in their demographic backgrounds, cultures and philosophies.

BackgroundWorking in multidisciplinary teams is indispensable for ensuring high-quality care for elderly people in Japan’s rapidly aging society. However, health professionals often experience difficulty collaborating in practice because of their different educational backgrounds, ideas, and the roles of each profession. In this qualitative descriptive study, we reveal how to build interdisciplinary collaboration in multidisciplinary teams.MethodsSemi-structured interviews were conducted with a total of 26 medical professionals, including physicians, nurses, public health nurses, medical social workers, and clerical personnel. Each participant worked as a team member of community-based integrated care. The central topic of the interviews was what the participants needed to establish collaboration during the care of elderly residents. Each interview lasted for about 60 minutes. All the interviews were recorded, transcribed verbatim, and subjected to content analysis.ResultsThe analysis yielded the following three categories concerning the necessary elements of building collaboration: 1) two types of meeting configuration; 2) building good communication; and 3) effective leadership. The two meetings described in the first category – “community care meetings” and “individual care meetings” – were aimed at bringing together the disciplines and discussing individual cases, respectively. Building good communication referred to the activities that help professionals understand each other’s ideas and roles within community-based integrated care. Effective leadership referred to the presence of two distinctive human resources that could coordinate disciplines and move the team forward to achieve goals.ConclusionTaken together, our results indicate that these three factors are important for establishing collaborative medical teams according to health professionals. Regular meetings and good communication facilitated by effective leadership can promote collaborative practice and mutual understanding between various professions.

Growth and differentiation factor 5 (GDF5) has been implicated in chondrogenesis and joint formation, and an association of GDF5 and osteoarthritis (OA) has been reported recently. However, the in vivo function of GDF5 remains mostly unclarified. Although various human GDF5 mutations and their phenotypic consequences have been described, only loss-of-function mutations that cause brachypodism (shortening and joint ankylosis of the digits) have been reported in mice. Here, we report a new Gdf5 allele derived from a large-scale N-ethyl-N-nitrosourea mutagenesis screen. This allele carries an amino acid substitution (W408R) in a highly conserved region of the active signaling domain of the GDF5 protein. The mutation is semi-dominant, showing brachypodism and ankylosis in heterozygotes and much more severe brachypodism, ankylosis of the knee joint and malformation with early-onset OA of the elbow joint in homozygotes. The mutant GDF5 protein is secreted and dimerizes normally, but inhibits the function of the wild-type GDF5 protein in a dominant-negative fashion. This study further highlights a critical role of GDF5 in joint formation and the development of OA, and this mouse should serve as a good model for OA.

BackgroundPost-treatment follow-up visits for gynecological cancer survivors should provide opportunities for management of adverse physical/psychological effects of therapy and early recurrence detection. However, the adequacy of such visits in Japan is poorly documented. We qualitatively explored care-seeking experiences of Japanese gynecological cancer survivors and deduced factors influencing care-seeking behaviors and treatment access.MethodsWe conducted 4 semi-structured focus groups comprising altogether 28 Japanese gynecological cancer survivors to collect a variety of participants’ post-treatment care-seeking behaviors through active interaction with participants. Factors influencing access to treatment for adverse effects were analyzed qualitatively.ResultsSurvivors sought care through specialty clinic visits when regular post-treatment gynecological follow-ups were inadequate or when symptoms seemed to be non-treatment related. Information provided by hospital staff during initial treatment influenced patients’ understanding and response to adverse effects. Lack of knowledge and inaccurate symptom interpretation delayed help-seeking, exacerbating symptoms. Gynecologists’ attitudes during follow-ups frequently led survivors to cope with symptoms on their own. Information from mass media, Internet, and support groups helped patients understand symptoms and facilitated care seeking.ConclusionsPost-treatment adverse effects are often untreated during follow-up visits. Awareness of possible post-treatment adverse effects is important for gynecological cancer survivors in order to obtain appropriate care if the need arises. Consultation during the follow-up visit is essential for continuity in care.
